Metrics details
selenocysteine (Sec) is delivered to the ribosome by selenocysteine-specific tRNA (tRNASec) with the help of a specialized translation factor
Sec-tRNASec recodes a UGA stop codon next to a downstream mRNA stem–loop
Here we present the structures of six intermediates on the pathway of UGA recoding in Escherichia coli by single-particle cryo-electron microscopy
The structures explain the specificity of Sec-tRNASec binding by SelB and show large-scale rearrangements of Sec-tRNASec
Upon initial binding of SelB–Sec-tRNASec to the ribosome and codon reading
the 30S subunit adopts an open conformation with Sec-tRNASec covering the sarcin–ricin loop (SRL) on the 50S subunit
Subsequent codon recognition results in a local closure of the decoding site
which moves Sec-tRNASec away from the SRL and triggers a global closure of the 30S subunit shoulder domain
These results reveal how codon recognition triggers GTPase activation in translational GTPases

Xork is being studied as a potential next generation immunoglobulin G (IgG) protease that will be developed by Astellas for use with AT845
adeno-associated virus (AAV)-based treatment for Late-Onset Pompe disease (LOPD) in adults
"Currently many patients are ineligible for clinical trials with investigational AAV gene therapy products due to the presence of naturally occurring antibodies against AAV gene therapy capsids," said Carsten Brunn
President and Chief Executive Officer of Selecta
"Xork has the potential to expand access to life-changing gene therapies by addressing pre-existing immunity to AAV
Most other IgG proteases in development are derived from common human pathogens
and as a result there is a high prevalence of pre-existing antibodies against these proteases that can restrict their use
Xork is differentiated by its low cross-reactivity to pre-existing antibodies in human serum
We are thrilled to partner with Astellas as they advance their robust gene therapy portfolio through the clinic."
"We are looking forward to partnering with Selecta as we strive to expand our therapies to a broader range of patients living with debilitating diseases
This agreement provides an opportunity to deliver potentially transformative gene therapy treatments to a specific population of LOPD adult patients who might otherwise be ineligible for clinical trials or treatment with Astellas' investigational product."
Selecta will receive a $10M upfront payment and is eligible to receive up to $340M for certain additional development and commercial milestones plus royalties on any potential commercial sales where Xork is used as a pre-treatment for AT845
Selecta is responsible for the development and manufacturing of Xork and will maintain the rights for the development of additional indications beyond Pompe disease
Astellas would have the sole and exclusive right to commercialize Xork for use in Pompe disease with an Astellas gene therapy investigational or authorized product
About AT845 for the treatment of Late-Onset Pompe Disease (LOPD) Astellas is developing AT845
a novel gene replacement therapy using an AAV8 vector under a muscle-specific promotor to deliver a functional copy of the GAA gene
AT845 is being investigated to determine whether it can deliver a functional GAA gene that is efficiently transduced to express GAA directly in tissues affected by the disease

The SSIS SEL Brief Scales (SSIS SELb) are multi-informant (teacher
and student) measures that were developed to efficiently assess the SEL competencies of school-age youth in the United States
the SSIS SELb was translated into multiple languages for use in a multi-site study across six European countries (Croatia
The purpose of the current study was to examine concurrent and predictive evidence for the SEL Composite scores from the translated versions of the SSIS SELb Scales
Results indicated that SSIS SELb Composite scores demonstrated expected positive concurrent and predictive relationships with scores from the Connor-Davidson Resilience Scale (CD-RISC) and negative relationships with scores from the problem behavior scales of the Strengths and Difficulties Questionnaire (SDQ)
these patterns generally were consistent across informants (parents
and students) and samples providing initial validity evidence for the Composite score from the translated versions of the SSIS SELb Scales
Limitations and future research directions are discussed
Considering the linguistic diversity present in Europe
many countries simply do not have access to validated translations of high-quality SEL measures
an adolescent self-report measure of resilience
Although comprehensive programs have been developed to promote SEL across schools in Europe, there is a lack of assessment compendia that recommend instruments to measure SEL, due in part to the scarcity of available measures intended for use across multiple countries. Cefai et al. (2021) recommended that SEL assessments be multi-modal
and strengths-based to accurately assess students’ social and emotional skills and competencies
schools generally rely on vague guidelines for choosing an assessment
rather than a specified instrument catalog
resulting in less standardized and psychometrically valid assessment practices
most schools across Europe rely on translated versions of existing screeners with little established validity evidence
and various student self-report instruments to assess students’ SEL competencies
Summary of psychometric studies of validity measures across countries
Our research strategy was to explore validity evidence for the SSIS SELb translations via examination of concurrent and predictive validity correlations between the SSIS SELb SEL Composite and scores from the SDQ and CD-RISC across participating countries
We expected several broad outcomes to emerge:
1) Because they measure similar positive social behaviors
we expected scores from the SDQ Prosocial Behavior subscale to correlate positively and moderately with scores from the SSIS SELb SEL Composite for all informants
2) Based on prior literature establishing negative relationships between positive SEL skills and emotional behavior concerns (e.g., Elliott et al., in press; Giannakopoulos et al., 2013)
we anticipated that scores from negatively valenced SDQ subscales (Emotional Symptoms; Conduct Problems; Hyperactivity/Inattention; Peer Relationships Problems) to correlate negatively and moderately to strongly with the SSIS SELb SEL Composite Scores across informants
3) Based on established relationships between SEL and resilience (e.g., Reyes et al., 2013)
to correlate moderately positively with the SSIS SELb SEL Composite scores
These anticipated outcomes specifically are in reference to concurrent validity correlations—we expected predictive validity correlations to be weaker in magnitude relative to their concurrent validity counterparts
Beyond evaluating these overall relationships
we compared them across countries to determine whether validity evidence was substantially different for any SSIS SELb translation
Demographic characteristics of concurrent validity samples
Different demographic characteristics were available for each sample based on what information was deemed relevant for each informant. A full breakdown of demographic characteristics of participants can be found in Table 2
Reliability coefficients (Cronbach’s α) for analytic measures across countries
The SDQ is an emotional and behavioral screening questionnaire developed to measure the mental health of children and adolescents from 3 to 16 years old. This measure is comprised of five subscales, four of which assess difficulties (Emotional Symptoms, Conduct Problems, Hyperactivity/Inattention, Peer Relationships Problems), and one assesses strengths (Prosocial Behavior; Goodman, 1997)
each distributed evenly across the five subscales
All responses are rated on a 3-point Likert scale (0: “not true”; 1: “somewhat true”; 2: “certainly true”)
The responses for the Prosocial Behavior subscale are reversed in valence so that the total score indicates the overall level of severity of problem behaviors
Some exceptions to this rule for internal consistency included the Conduct Problems and Peer Relationship Problems scales of the parent and student report forms
the Greek self-report sample had notably lower test-retest reliability coefficients relative to other countries
the Romanian student self-report sample and the Greek parent report sample
Reliability coefficients for the current sample were fairly strong with the exception of the test-retest reliability coefficient for the Greek sample
In the piloting phase it was decided that 1,000 students were to be selected from each of the six participating country
clustered by group (experimental control) and by age (4–6
lower secondary and upper secondary students
The 250 students selected from each age cohort were to be allocated equally in the experimental (125) and control (125) groups
The expected total sample size (6,000) would guarantee a maximum margin of error of 1.27% assuming a 95% confidence level
Cluster sampling was used to select the schools ensuring good geographical representation (and age and school level)
while stratified sampling was used to select the students from several classrooms within the selected schools
Selected students and their respective teachers and parents then completed the respective questionnaires
The administration of questionnaires was either completed online (in the case of teachers and older students) whilst in most instances parents completed the questionnaires manually and returned them sealed to the school; in such instances the researchers from that particular country then inputted all answers in the electronic data base
The data file was accessed only by the project evaluation team led by the University of Malta
the primary school students completed the questionnaire manually in class
with data inputted into the electronic data base by the respective research teams
Ethical approval was obtained from the respective academic institutions and educational authorities and all participants gave their consent before completing the questionnaires
The project evaluation team at the University of Malta in collaboration with the project coordination team at the University of Milano-Bicocca worked with the main researchers in the six implementing countries to ensure quality implementation and evaluation of the program
including translation and use of instruments
and duration and frequency of implementation were agreed upon by the whole team to ensure consistency in program implementation and evaluation
a training support team was set to coordinate activities related to the training courses and supervisions of teachers
the translation and adaptation of the handbooks and guidelines and to organize and lead the meetings for school leaders and parents
Teachers in the experimental condition received 16 h of initial training in order to receive practical and theoretical knowledge about mental health promotion in the school context as well as tools and materials to implement the program
The training was carried out face to face and/or remotely depending on national COVID-19 health regulations
teachers also received 9 h of mentoring and monitoring by qualified program trainers
The implementing teachers were provided with a manual of activities developed by the consortium as part of the project; their students and parents also received a handbook
A set of procedures were also applied to monitor the quality of the implementation across schools and countries
These included the assessment of program’s fidelity (the extent to which the implemented intervention corresponds to the originally intended program)
dosage (which refers to how much of the intervention has been delivered)
quality (related to how well different program components have been conducted)
participants’ responsiveness (referring to the degree to which the program stimulates the interest and engagement of participants namely teachers
and parents) and adaptation (related to changes made in the original program during implementation
not all teachers were able to do 12 activities
with the number of sessions varying considerably particularly between countries due to health policies in place related to the pandemic
The majority of the 423 implementing teachers (59%) completed 10 or more activities
but 31% completed only 4 or fewer activities
small correlations ≈0.10; medium correlations ≈0.30; large correlations ≈0.50)
We completed our correlational analyses twice: first with concurrent data and second with predictive data
we used pre-test data from the broader study and included both experimental and control cases because neither group had received intervention at pre-test
we only used control cases to ensure that the provision of the intervention being tested would not influence our results
and student versions of the SSIS SELb and outcome measures; however
the CD-RISC was only used with student respondents
Mean scores and their standard deviations for all measures by country-focused samples and informants are documented in Table 4 (Concurrent validity sample) and Table 5 (Predictive validity sample). Validity correlations are presented in Table 6 and cross-country comparisons in validity correlations are found in Table 7

the correlation for Portugal (r = −0.29) was statistically larger in magnitude than the correlation for Italy (r = 0.02)
but no other correlations were statistically significantly different across countries
This study was undertaken to examine concurrent and predictive validity evidence for the Composite scores from the translated versions of the multi-informant SSIS SELb Scales. This universal screening scale was developed in the United States and based on the CASEL five competency framework (CASEL, 2015)
and parent forms of this assessment of children’s social emotional learning were translated as part of an investigation of the effectiveness of a mental health program (PROMEHS) delivered in schools across six European countries
Using existing translated versions of the SDQ
a widely used multi-informant rating scale of children’s prosocial and problem behavior
a self-report measure of resilience behaviors
assessment results for large and representative samples of children were used to provide insights regarding the theoretical construct of SEL competency and validity of scores from translated versions of the SSIS SELb Scales
This construct and social behavior representative of it was the central outcome variable of the PROMEHS project and expected to be associated with children’s mental health and school success
As expected based on our guiding theory about the development and relevance of SEL competences to children’s mental health and schooling
to support that SDQ Prosocial scores of students
were correlated positively and moderately with the SSIS SELb SEL Composite
the validity coefficients were highly consistent across the six participating countries and three informant types
with (a) concurrent correlations always stronger than their corresponding predictive correlations and (b) nearly all these correlations in the moderate to high range
These findings provide strong evidence of the convergent validity of scores from the translated SSIS SELb scales
there was substantial evidence from students’ self-ratings to support the supposition that scores from the 10-item CD-RISC correlated moderately positively with the Composite SEL scores on the SELb
across all countries (a) the concurrent validity coefficients were higher in magnitude than the predictive coefficients and (b) nearly all the indicators of the relations between the SEL and resilience scores were in the moderate range
It does suggest that students’ self-ratings should be interpreted with these considerations in mind
the fact that it held for student raters as well could also point to differential relations with negative behaviors and outcomes that could be important foundations of future validation work for the SSIS SELb and similar measures
Our cross-country comparisons also yielded some interesting and potentially important results
The most striking trend was that validity evidence
tended to be weaker in magnitude for the Portuguese SSIS SELb and stronger in magnitude for the Romanian SSIS SELb
These patterns held only for teacher and parent informants and did not seem to be present for students
Although these patterns could indicate problems with the translation of the Portuguese SSIS SELb
this seems unlikely because the differential validity relationships were only present for the SDQ Emotional Symptoms
It is possible that these SDQ scales have some translation or validity issues that need to be resolved with further research
it is possible that cultural differences in Portugal and Romania explain the weaker relationship between SEL and these social constructs in Portugal and the stronger relationship between them in Romania
Future cross-cultural research is warranted to better understand the nature and importance of SEL across European cultures
although it was not the goal of this study to consider the reliability of these translated scales
the reliability of scores from the SSIS SELb were strong and would support widespread research applications and
A notable exception to this conclusion was for the Greek SSIS SELb-S
which showed notably lower test-retest reliability than SSIS SELb scores from other informants or countries
This finding held for other informants in Greece (parents) and for other scales with Greek students (both the SDQ and the CD-RISC)
so it may have been an idiosyncratic feature of data collection of this study
further research is necessary to support the use of the SSIS SELb in Greece
Extant group studies could evaluate whether this pattern and other known patterns across extant groups (e.g.
disability status; socioeconomic status; etc.) holds with scores from translations of the SSIS SELb to further support the validity of scores from these measures
although the validity data from the study provide promising evidence for score inferences
more data are needed to support specific applications in European schools
Because the SSIS SELb was created primarily to be a universal screener
conditional probability analyses might be a most profitable next step
and base rate data would be beneficial as well
although the SSIS SELb is not scored based on norm-referenced score interpretation
further work evaluating whether its criterion-referenced scoring approach is cross-culturally equivalent would greatly support the use of the SSIS SELb in the included European countries
multi-informant study with translated versions of the SSIS SELb Scales provide support for the validity of their score inferences
the patterns of convergent and predictive validity indices for these translated measures of social emotional learning were consistent with our theoretical model of SEL competence
and were quite consistent across the six European countries with a diverse sample of children
Although additional research is necessary regarding specific applications of each translated version of the SSIS SELb Scales
concurrent and predictive relations provide promising evidence for the validity of the Composite scores across multiple informants

There are more than 600 people on the waiting list to get a plot at one of the city’s community gardens
vegetables and herbs in a 400-square-foot plot at the Moiliili Community Garden
one of 10 city-run and city-funded community gardens on Oahu
Right now the 38-year-old medical technician is growing collard greens
cassava and a smattering of native ferns and plants
He says there are times when 100% of the produce he consumes comes from this small garden
“It started off as something that I could do to grow my own food
who lives in an apartment in Makiki with no lanai or garden space
it’s had a major therapeutic and mental health impact on me
Sometimes I go to the garden literally to just be there.”
has fostered an appreciation in growing plants
the gratification I get when a seed I planted has sprouted into a plant that’s providing me food
I’m lucky, though. Where I live I have enough outdoor space to grow beans, sweet corn, kale, apple and lemon trees, carrots and beets. With so much of Oahu’s population living in condos or densely populated urban neighborhoods — and our state’s heavy reliance on imported food — the city’s community gardens program is a vital piece in food security and sustainability
and it seems like this program should get way more attention — and
Expansion is happening — slowly and maybe a bit unconventionally — but it is happening
With funding from the American Rescue Plan Act
the city was able to hire a community gardens project manager
who has been assessing the current program and looking at feasible
something Oahu residents have been requesting for years
It’s not uncommon for people to be on the waitlist for high-demand gardens — Ala Wai
the city installed seven ADA-accessible raised garden beds at the community garden next to Foster Botanical Garden
The 10-foot by 10-foot beds are high enough that a wheelchair can fit underneath them
Mines is also working with various community groups
schools and nonprofits to help them with their own urban gardens
She’s creating a comprehensive guide with information about how to start and maintain a community garden in the Islands
“The city has 50 years of expertise running the community gardens program,” she says
there are more than 600 people on the waiting list to get a plot at one of the city’s 10 community gardens
Mines says the city is planning to open its 11th garden within the next five years — its first since the 1990s
it needs consistent funding and staff support
Starting a community garden isn’t as easy as measuring out plots and assigning them to residents
That’s where creative partnerships have worked
In December 2020 the Honolulu Department of Community Services created more than 160 garden beds and planted 20 fruit trees at seven city-owned special-needs housing locations
including kupuna housing in West Loch and Manoa and shelters for homeless and at-risk families
The project was funded by a Food Security-Scaping Program seeded with CARES Act Coronavirus Relief Funds
The city’s community gardens program offered the inspiration and knowledge to this project
sustainable produce to those most affected by the pandemic
The city has also provided its expertise to Kuilima Farm, a 468-acre agricultural parcel owned by Turtle Bay Resort in Kahuku. The farm, managed by Pono Pacific
has 34 community garden plots available to North Shore organizations and residents
“Finding the land for a community garden isn’t the hardest part,” Mines says

Near-infrared spectroscopy (NIRS) is susceptible to signal artifacts caused by relative motion between NIRS optical fibers and the scalp
These artifacts can be very damaging to the utility of functional NIRS
particularly in challenging subject groups where motion can be unavoidable
A number of approaches to the removal of motion artifacts from NIRS data have been suggested
In this paper we systematically compare the utility of a variety of published NIRS motion correction techniques using a simulated functional activation signal added to 20 real NIRS datasets which contain motion artifacts
and Kalman filtering approaches are compared to one another and to standard approaches using the accuracy of the recovered
simulated hemodynamic response function (HRF)
Each of the four motion correction techniques we tested yields a significant reduction in the mean-squared error (MSE) and significant increase in the contrast-to-noise ratio (CNR) of the recovered HRF when compared to no correction and compared to a process of rejecting motion-contaminated trials
Spline interpolation produces the largest average reduction in MSE (55%) while wavelet analysis produces the highest average increase in CNR (39%)
we recommend the routine application of motion correction techniques (particularly spline interpolation or wavelet analysis) to minimize the impact of motion artifacts on functional NIRS data
movement of the head of the subject will invariably cause motion between each optical fiber and the scalp
This relative motion will cause a rapid shift in the optical coupling between the fiber and the scalp
which typically results in a period of high-frequency noise in the recorded NIRS data
the optical coupling is often irrevocably altered
causing a shift in the baseline measurements of HbO and HbR
Because the magnitude of this motion-induced noise is typically far greater than the changes associated with tissue hemodynamics
any changes in hemoglobin concentrations in the cerebral cortex which coincide with motion artifacts are usually so heavily contaminated that they are indiscernible
once motion artifacts have been identified
there is no well-established approach to their removal or correction
the standard approach to motion artifacts in functional NIRS data is to either attempt to insure that there are enough stimulus trials to minimize the average impact of the artifacts or simply to remove any stimulus trials that coincide with identified artifacts
Subject groups that tend to exhibit extensive motion are often also the groups for whom the duration of NIRS recording is limited
In such cases the number of stimulus trials is also limited
This can make it impossible for motion artifacts to be removed by a process of averaging
while trial rejection can reduce the effective number of stimulus trials even further
reducing the contrast-to-noise ratio (CNR) of the estimated hemodynamic response function (HRF)
Motion artifacts are typically observable in multiple NIRS channels and have a scale and frequency composition that are distinct from the background NIRS signal
a variety of signal processing approaches have emerged that attempt to reduce or remove motion artifacts from functional NIRS data
in order that the corrected data can contribute to the estimated HRF
In the context of NIRS experimental design
these motion correction methods fall in to two distinct categories: those which require some additional input beyond the standard NIRS dataset (and therefore require an alteration of experimental design) and those that do not
state-space based approach to the recovery of signals that are contaminated by noise and (assuming the NIRS time-course contains some periods of data that are motion-free) can be applied without the need for additional inputs
but it was not possible to meaningfully quantify the improvement because the true hemodynamic response was unknown
In this paper we present a systematic comparison of four recently promoted motion correction algorithms by applying them to real motion artifact contaminated NIRS data
By adding a number of synthetic HRFs to each dataset and then attempting to recover the average HRF
we are able to simulate a functional NIRS study and assess each motion correction technique in terms of the improvement in the accuracy of the recovered HRF
The accuracy of this recovery can then be compared to that achieved without motion correction and by simply removing motion-contaminated trials entirely
If the standard deviation increases by a factor exceeding SDThresh
or the peak-to-peak amplitude exceeds AMPThresh
then data from the beginning of that window to tMask seconds later is defined as motion
tMotion = 0.5 s and tMask = 2 s are effective in most cases
as we did not wish to test the validity of this detection approach here and simply needed to identify motion as accurately as possible
SDThresh was fixed individually for each dataset (at values between 12 and 20) in order to maximize the accuracy of motion identification as determined by visual inspection
(Note that the output of this algorithm is not channel-specific
signal changes which are determined to be artifact in one channel are marked as motion in all channels; this relies on the reasonable assumption that motion artifacts affect multiple channels)
an average of 10.6% of each NIRS dataset was identified as motion
The average duration of a given period of artifact was 4.2 s (though note that tMask = 2 s determines the minimum length of each motion artifact)
This suggests that the majority of artifacts are brief
and likely take the form of transient spikes
This is consistent with our experimental experience
The application of PCA transforms an N-measurement NIRS dataset into N linearly uncorrelated components
ordered by their contribution to the variance of the data
The magnitude of motion artifacts is typically much larger than the background NIRS signal
Motion artifacts are also typically present on multiple NIRS channels
The application of PCA to the filtering of NIRS data makes the assumption that motion artifacts provide the dominant contribution to the variance of the NIRS data
and that therefore the first r principle components will account purely for motion artifact
These r components can then be removed before the data is analyzed further
the PCA motion correction consists of first performing singular value decomposition on the spatial correlation matrix YTY such that:
where U is the orthogonal matrix of spatial eigenvectors and Ω is a diagonal matrix of the associated eigenvalues, both of dimensions N × N (Zhang et al., 2005)
The first r eigenvectors can then be removed from the data
where Ar is a N × N matrix with the first r diagonal elements equal to 1
The performance of PCA in removing motion artifacts from NIRS data is heavily dependent on two factors: the number of NIRS measurements in a dataset [as this defines the number of components (N)] and the number of components that are removed (r)
Note that the number of NIRS measurements is twice the number of channels as we define them: each channel consists of measurements at two different wavelengths
The optimum value of the parameter r will clearly depend on the total number of components (N) and on how many of those components constitute artifact
A simple way to approach the selection of r is to normalize the diagonal elements of the matrix Ω by their sum to produce the vector Ω˜
The nth element of Ω˜ then provides a measure of the proportion of the NIRS data variance that is accounted for by the nth component
By fixing the proportion of data variance that is to be removed (referred to from herein as σ_PCA)
the number of components to remove (r) can be defined by finding the lowest value of r for which:
We employed the discrete wavelet analysis and filtering approach described by Molavi and Dumont (2012). While a detailed description of wavelet decomposition is not provided here (see Strang and Nguyen, 1996; Molavi and Dumont, 2012) in summary each NIRS data time-course
is transformed into the wavelet domain using the general discrete wavelet transformation:
The approach described by Izzetoglu et al. (2010) was the basis for our Kalman filtering of NIRS motion artifacts
Kalman filtering is a state-based recursive technique that acts on noisy data to provide a statistically optimal estimate of the underlying signal and is essentially a two-step process
The first is to use prior knowledge of a state to make a prediction of a future state and its uncertainty
This prediction step models the state x at time = k
based on the state at time = k−1 such that:
where A is the transition model (which uses knowledge of the prior state to predict the current state) and γk is the system noise
This prediction is then compared to the actual measured state at time = k
which is modeled as a function of the true state x:
For the application of the Kalman filter to the reduction of NIRS motion artifacts, the translation model was an auto-regressive model based on the Yule–Walker method, with a model order M = 4. This was the highest model order that remained stable on application to our data, and is also that recommended by Izzetoglu et al. (2010)
The M Yule–Walker coefficients were calculated on a measurement-by-measurement basis by taking the correlation between the longest period of motion-free data and itself
The system and measurement noise were taken to be the variance of the motion-free NIRS data and the variance of the entire time-course respectively for each NIRS measurement
periods of motion were determined by the algorithm hmrMotionArtifact
Figure 1 shows an example of a single motion artifact in a period of NIRS data
and the results of the correction of that motion artifact using a band-pass filtering
and Kalman filtering (all also in combination with the same band-pass filter
A single motion artifact from one of our 20 NIRS datasets and the effect of band-pass filtering (between 0.01 and 0.5 Hz)
Note that the same band-pass filter is also applied after each motion correction technique
These amplitudes are approximately equivalent to an intensity change of 0.9% from baseline for the 690 nm channels and 2% from baseline for the 830 nm channels
Three of the eight NIRS channels from each of the 20 NIRS datasets were randomly selected and the simulated HRF was added to the OD time-course of these channels at the 25 onset positions defined by the timing vector
the automatic motion detection algorithm hmrMotionArtifact was applied to each NIRS dataset to define periods of motion after the simulated HRFs had been added to the data
Once the simulated functional dataset had been completed, it was then passed through six different processing streams. The first was the recovery of the HRF without motion correction or the rejection of trials. The data was band-pass filtered (a third order Butterworth filter between 0.01 and 0.5 Hz) to remove low-frequency drift and cardiac oscillations before being converted into HbO and HbR using the modified Beer–Lambert law (Obrig et al., 2000)
The periods of data around each of the 25 stimulus trials were then block-averaged to produce the mean HRF
The second processing stream was a standard trial rejection NIRS processing approach
After band-pass filtering the output of hmrMotionArtifact (calculated previously) was applied such that if a stimulus trial coincided with a defined period of motion
The remaining stimuli periods were then block-averaged in order to recover the mean HRF
The first step of the remaining four processing streams consisted of the implementation of each of the four motion correction techniques: PCA
The resulting corrected data was then subjected to the same band-pass filter as the standard processing approaches
irrelevant of how effective the motion correction process may have been
were then included in the block-average calculation of the mean HRF
This entire process was repeated five times for each dataset using a different random selection of channels and a different stimulus timing vector in order to improve the robustness of the results
The result of the simulation process described above was 300 HRFs (20 datasets × 3 channels × 5 repetitions) for each of the six processing streams (no correction
Three metrics were then calculated for each processing stream
These consisted of the MSE between each recovered HRF and the true (simulated) HRF
the Pearson’s correlation coefficient (R2) between the recovered and true HRF and finally the CNR of the recovered HRF
The CNR was calculated by taking the mean of the 2 s of recovered HRF data centered at the true HRF peak time (7 s after onset) and dividing by the standard deviation of the 5 s of data prior to onset
These three metrics allow a direct comparison of the accuracy of the HRFs recovered via standard NIRS processing approaches and via each motion correction method
All metrics are calculated on the basis of the recovered HbO signal only for computational simplicity
Several of the motion correction techniques applied here require the selection of an input parameter that can significantly affect the performance of the technique
these parameters are the percentage variance to remove (σ_PCA)
the interpolation parameter (p_Spline) and the probability threshold (α_Wav) respectively and are described above
In order to optimize the performance of each of these methods
it was first necessary to perform a sensitivity analysis for each of these three techniques
The simulation described above was repeated
for a variety of values for each input parameter
Guided by the values of these parameters applied in previous publications
and α_Wav was varied from 0.01 to 0.8
trial rejection actually increases the MSE
However in this simulation the difference between the MSE for the trial rejection and no correction approaches is not significant in a two-tailed paired t-test (p = 0.18)
Figure 2. The MSE between the recovered and true HRF for 300 simulations using trial rejection (y-axis) and no correction (x-axis). Trial rejection produces an increase in MSE in 62% of cases, but there is no statistically significant difference between the MSE achieved by trial rejection and that of no correction. The red asterisks indicate the simulations corresponding to the HRFs shown in Figure 3
These three optimized parameter values were employed in all remaining analyses
Examples of recovered hemodynamic response functions
(A) Is a case where the initial (“no correction”) HRF is very poor and PCA
and wavelet approaches can be seen to improve it
(B) Is a case where the initial HRF is reasonably accurate but likely contaminated by motion
Here the HRF is improved by trial rejection and all four motion correction techniques
(C) Shows a case where the initial HRF is very accurate
Trial rejection is detrimental to the HRF as are PCA
Scatter plots showing the MSE of each HRF recovered via PCA (A)
plotted against that achieved by no correction
A clear trend is apparent for wavelet analysis (and to a lesser extent PCA) that indicates a tendency for the MSE to be increased in cases where the initial (no correction) value was low
while a decrease in MSE is reliably achieved if the initial MSE is high
Scatter plots showing the CNR of each HRF recovered via PCA (A)
Figure 4 shows scatter plots of the MSE of the 300 HRFs recovered via PCA (Figure 4A), spline (Figure 4B), wavelet (Figure 4C), and Kalman (Figure 4D)
plotted against those achieved with no correction
the MSE decreases significantly (p < 0.01
Note that the decrease is also significant for all four techniques when compared to the trial rejection approach
All four techniques produce an increase in MSE in a subset of cases (32
All four techniques also show a trend which indicates that motion correction is much more likely to have a detrimental effect if the initial (no correction) HRF has a low MSE
This is particularly clear for wavelet analysis
where an increase in MSE is common if the uncorrected value was below 10 μM2
while a decrease in MSE is assured if wavelet analysis is applied when the uncorrected MSE is greater than 20 μM2
cases where the initial CNR was between approximately 5 and 15 show a consistent improvement
particularly for wavelet and Kalman filtering
Each box plot shows the median (line and notch)
the 25th and 75th percentiles (the edges of each box) and the most extreme values not considered outliers (whiskers)
(A) shows the MSE for no correction (“None”)
and each of the four motion correction techniques
(B) shows the percentage change in MSE relative to no correction
(C,D) show R2 and CNR for no correction (“None”)
and wavelet approaches produce a median decrease in MSE of 38
Kalman filtering produces a decrease of only 21%
All four methods produce an increase in R2
and wavelet approaches are highly significant (p < 0.01) the change due to Kalman filtering is not significant (p > 0.05)
All four methods also produced a significant increase in CNR
with wavelet filtering yielding the highest median CNR at 10.9 compared to 6.9 for no correction
The pair-wise percentage change in CNR (not shown) was also greatest for wavelet analysis
The simulations performed here are designed to closely mimic a real functional NIRS experiment
but they still have a number of limitations
and our results will not apply to all datasets and all experimental paradigms
the performance of PCA is heavily dependent on the number of NIRS channels in a dataset
Another potential limitation is the choice of dataset
It is possible that the types of motion artifact
the background hemodynamic oscillations and the quality of NIRS recording are different in these 20 stroke patients than in a standard functional NIRS study
we believe these effects are likely to be negligible
One surprising result is that trial rejection does not produce a significant improvement in the recovered HRF compared to no correction (Figure 2)
This is almost certainly due to the range of the number of trials rejected in these datasets
The minimum number of trials rejected in our simulations was 7 out of 25
It is extremely likely that trial rejection would provide a significant improvement compared to no correction if only a small number of trials were initially rejected
As the proportion of rejected trials increases
the more likely it is that including those trials will produce a better HRF than rejecting them
as motion artifacts will be minimized simply by block-averaging
All four motion correction techniques produce an improvement in HRF recovery on average. Spline interpolation provides the highest average decrease in MSE (55%), reduces MSE in 80% of cases (Figure 4) and produces the highest average R2 (Figure 6) while wavelet analysis provides an average decrease in MSE of 50%, reduces MSE in 77% of cases and produces the highest average CNR (Figure 6)
best technique depends on which metrics are considered
it is clear that spline and wavelet techniques are the most successful
The results of Figures 4–6 show that in practice there will be cases where motion correction will be detrimental. The distributions shown in Figures 4A–D suggest that this is much more likely in cases where the uncorrected HRF is already very accurate
These cases of low initial MSE are the cases where the number and/or amplitude of motion artifacts is/are small
In cases where only a small proportion of stimulus trials are affected by motion artifacts
correction approaches may not be suitable and the standard approach of trial rejection would likely be preferable
This result is clearly expected for PCA and wavelet approaches
the assumptions on which the PCA and wavelet approaches are based will begin to break down and both techniques will begin to remove components of the data that have a physiological origin
The fact that wavelet analysis exhibits a clear relationship between the uncorrected MSE and the improvement it can provide may give it an advantage over spline interpolation
It may be possible to define a threshold (based on the proportion of data that is affected by motion artifact or the uncorrected CNR) that will determine whether the application of wavelet analysis is suitable and therefore avoid cases where wavelet analysis will be detrimental
Although we have attempted to apply these pre-published motion correction techniques in the manner described by their respective authors
there are a number of ways in which these techniques could potentially be improved without the need for additional external inputs or for alteration of an experimental paradigm
One obvious example is to target the PCA and Kalman approaches so as to only examine periods of data that are pre-determined as motion
Wavelet analysis takes advantage of the abnormal spatial and temporal characteristics of motion artifacts in the wavelet domain to identify and remove them
Spline interpolation requires knowledge of the location of motion artifacts throughout the dataset
and interpolation is only performed for those periods
PCA and Kalman filtering are applied to the entire NIRS time-course
including periods where we do not believe there is motion artifact
These algorithms could easy be altered so as to only be applied during periods of identified motion artifact
The variance of the NIRS signal that is due to motion artifact during periods identified as motion artifact will obviously be very large
Applying PCA with a high value of σ_PCA to only those periods may produce better results that applying PCA to the entire dataset
particularly in cases where motion is not particularly prevalent and therefore accounts for a lesser proportion of the variance of the entire dataset
Another obvious advance would be to employ trial rejection in conjunction with a given motion correction technique
It would be trivial to apply hmrMotionArtifact to identify motion artifacts still present in the corrected NIRS data and remove any stimulus trials that remain contaminated
One can also conceive of a recursive technique whereby motion correction is performed repeatedly until no motion artifacts are detected
we set out to test only those motion correction techniques that can be applied after NIRS data acquisition
without altering the experimental design and without the need for additional external inputs
While we believe this is the most relevant approach to motion correction for the majority of NIRS applications at present
We believe the application of both of these techniques can be highly beneficial to functional NIRS analysis
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest

Set in expansive grounds with an adjoining campsite, the Jochen-Klepper-Haus, a converted villa formerly belonging to the director of a porcelain manufactory, is a highly attractive location well known beyond the region. An architectural competition was initiated to extend the programme by three event halls and the necessary infrastructure with the objective of further developing the venue and making it suitable as a community centre for the Selb-Plößberg district.
As a supplement to the historic villa with its colourful clinker facade, the new building has been developed as a timber frame construction which, through its permeability, links indoor and outdoor space and thus maximises the spatial potentials of the site: the existing population of trees and clearings, the villa’s garden to the west and the view out into the surrounding landscape to the east have become reference values of the location.

While history has cast Adolf Hitler as a trailblazing propagandist
he has also been portrayed as a successful political campaign speaker - but does this narrative stand up to scientific scrutiny
Political scientists from the University of Konstanz and the Hertie School of Governance have now revisited the question as to how effective Adolf Hitler's public campaign appearances were in garnering electoral support in Weimar Germany
to be published in the American Political Science Review (APSR)
suggest that Hitler's appearances actually had a negligible impact on the Nazi's electoral fortunes before their seizure of power in 1933
Five German parliamentary (Reichstag) elections and one German presidential (Reichspraesident) election were carried out in Germany between 1927 and 1933
the National Socialist German Workers' Party (NSDAP) increased its vote share from a marginal three to an extraordinary 44 percent
New research results from Professor Peter Selb at the University of Konstanz and Dr Simon Munzert from the Hertie School of Governance show
that Adolf Hitler's 455 public appearances during this period had a surprisingly small effect on the electoral outcomes
Peter Selb and Simon Munzert base their findings on election statistics from 1,000 counties and districts as well as from 3,864 municipalities
For their analyses they include information on Hitler's campaign locations
They also take campaign event appearances of Joseph Goebbels - the second most important speaker for the Nazi movement - into account
By using the statistical method of "difference of differences" (DID)
the researchers compare election trends in areas where Hitler gave public speeches with the electoral trends from similar areas where he did not appear
"We are surprised about how marginal the effect of Hitler's election appearances was
especially when one considers contemporary witnesses and historians who have confirmed his exceptional rhetorical abilities"
their data assessment demonstrates only minor electoral effects
which were very limited in terms of geography and time
Hitler's personal involvement only had a positive effect in the run-off election for the office of German president in 1932
This election took place after an unusually short
intensive and one-sided election campaign - competitor Hindenburg did not make any public appearances - leading Hitler to garner an estimated additional one to two percentage points in terms of vote share in counties and districts in the immediate vicinity of locations where he made a public appearance before the election
The fact that Hitler's campaign is considered a most likely case for campaign effects makes these results all the more extraordinary
Hitler utilised new and sophisticated techniques
including modern technology such loudspeakers and airplanes
These provided Hitler an unparalleled geographic penetration and an unprecedented level of public attention
"It is remarkable that Hitler's public appearances and speeches as an early populist and party leader were not very influential
especially when one considers the growing body of empirical evidence confirming his propaganda successes as dictator"
Research on Germany after 1933 - when the Nazis had begun to gain totalitarian control over the state apparatus
and the emerging mass media - has demonstrated that Nazi propaganda had strong and long-lasting effects on the collective perceptions
"other studies stress the crucial role that economic and political circumstances played during this time - which includes mass unemployment and economic hardship
the alienation between established parties and the electorate
as well as weak state institutions - for the rise of the NSDAP
we can confirm that Hitler's importance as a charismatic speaker is less significant." Based on this historical evidence
the researchers recommend that one should view the accepted opinion that charismatic leaders play a key role in the rise of right-wing populist movements

Republicans Larry Wallace and Vince Nestore broke the Democrats’ 15-year
7-0 hold on Gloucester County freeholder board
Their election put the majority under scrutiny that it had not seen for more than a decade
Unfortunately, both Republicans capped their freeholder careers after a single term. Wallace is running for the Assembly. Nestore dropped a re-election bid in June
This gives voters four non-incumbents for two seats. Our choices are Republican Ed Selb and Democrat Dan Christy.
impressed our editorial board with his public safety experience
An opponent of his hometown joining the county’s regional EMS service (Harrison Township signed up anyway)
he could provide reasonable counterpoint to the Democrats’ gospel that shared services always save money and run like clockwork
Christy (don’t confuse his name with the Republican governor’s) is a carpenter’s union official
He’s recommended mostly as the best of a trio who project mediocrity
the Washington Township resident could connect with the concerns of county parents
A reservation is that he conforms to state Sen
Stephen Sweeney’s mold for big-labor candidates who show little independent thinking as freeholders
Christy deserves a shot over former Democrat freeholder Frank DiMarco
He did not serve with enough distinction to return him to the board
does not seem better prepared this time around
The freeholders’ closing of the county jail this year shut out the public until it was virtually a done deal
Selb and Love want freeholder meetings recorded for broadcast
who pushed many of the transparency reforms that the board has adopted
They’re not hanging around for second terms
— The “digital divide” cuts deep and wide across South Jersey
but a partnership of this rural township and Comcast Corp
promises to allow broadband access everywhere here by early 2024
Hopewell and Comcast will carry out a roughly $1.5 million project to extend existing broadband service to every corner of the township and its approximately 4,400 residents
The timetable places the completion date for the first-of-its-kind project 14 months from now
I’m very excited to be part of the team that’s been able to bring broadband to the entirety of Hopewell,” Mayor Paul Ritter said
someone can live in Hopewell Township and work anywhere in the country
This is something that the township has been working toward for 10 years.”

Ritter and township Administrator Leo Selb said that decade-long push owes much to Greg Facemyer
first as a committeeman and finally as deputy mayor
“He was extremely instrumental in making this happen
He went up and fought with BPU (Board of Public Utilities) originally
Facemyer finished his last day as a township official at the start of the year
Ritter and Facemyer said the COVID-19 pandemic really energized the push for 100 percent township access
Areas not served by Internet cable have had to struggle along with wireless coverage
“And it’s such a great impact to a small community like ours because now we can at least compete with other businesses,” Facemyer said
“The students don’t have to go to their grandparents or a relative that does have broadband to complete tests or do their studies because at their (own) homes it’s so unreliable if they’re in an unserved area.”
also effectively rejects a competing Internet access development concept from Cumberland County
The county proposes building its own broadband infrastructure to cover Cumberland and Salem counties
the long and the short of it is the county has a very
much more complicated approach to it,” Facemyer said
“Instead of the county going to Comcast and saying
‘Do a survey of Cumberland County and tell us who is unserved.’ And they can do that through their records and their engineering department
Comcast officially declined to support that proposal
responding to a county request for its backing
evaluated the initiative as not meeting the true internet access needs of the area and also as unlikely to be financially viable
Ritter and Facemyer said the lack of access in the township
a very rural and agricultural area covering almost 30 square miles
also has been a killer to real estate activity and values
That was another major factor in the Comcast agreement
“We have had numerous circumstances where residents have contracted to sell their homes and the buyer
in their due diligence prior to settlement
find out that some residents don’t have broadband or cable TV or the Internet,” Facemyer said
“They’ve backed out of real estate transactions because they work from home or whatever reason they certainly want broadband
I think the values of the homes will improve.”
A town hall for residents who could sign up for service will be held at Hopewell Crest School on Sewall Road
and will have Comcast representatives to talk about the project
Selb said there are at least 144 houses that are unserved now
There will be no connection fee to potential customers with properties 300 feet or less from utility poles that will carry the new lines
Selb said 22 houses and three businesses fall outside the 300-foot zone
Those owners would have decisions to make about cost versus access
The project starts with at least several months of engineering work and obtaining approvals and easements
The construction will be covered by three sources of funding
including money from an approximately $1.08 million bond the Township Committee approved in September 2022
Selb says not all the bond will be used because of the other funding pieces available
Comcast is putting up $407,694 or 27 percent of the cost
The company was the only one to respond when Hopewell sought Requests for Proposals from broadband providers
Selb said the township end should be $656,791 or 43.5 percent
“And the first phase is specifically engineering money ..
They are going to pay up all those costs until their funds have been exhausted
the next step will be to go to American Rescue Plan funds.”
Selb said one challenge in getting to a deal with Comcast was getting the company to understand New Jersey law on government contracting
every town will benefit from our forging through the waters to make it happen."
Selb said Maurice River Township recently finalized a very similar agreement with Comcast
Other communities also have been in contact with questions about Hopewell’s experience
In a letter in September to Cumberland County
Comcast said the Federal Communications Commission estimates 2.7 percent of homes in Cumberland County are not in reach of “fast
reliable wired broadband networks” and another 21.6 percent could have service but do not subscribe
Ritter said the importance of broadband access today is comparable to access water and sewer services
residents will have access to its Xfinity suite of internet products
“including supersonic WiFi technology” and Flex entertainment platform
The project also is touting to residents the availability of the federal Affordable Connectivity Program
The program provides low-income households a credit of up to $30 per month toward their internet and mobile services

Gebrüder Netzsch Maschinenfabrik went on to develop machines for ceramic production
Netzsch remains a family-owned company once again headed by two brothers from Selb: Moritz and Paul Netzsch
As the fifth generation of the Netzsch family of owners
they run the company along with CFO Jens Niessner
Netzsch operates three business units: Pumps & Systems
Grinding & Dispersing and Analyzing & Testing
The company has around 210 production and sales locations worldwide
“It is important to me that we have a stable
continued development of what we do today,” says Moritz Netzsch
with all the necessary rethinking and new thinking
and bring the company into the next generation stronger than ever.”
Netzsch has had its corporate history researched from a variety of perspectives for its 150th anniversary
“Our history provides answers as to why we have existed for so long,” says Paul Netzsch
“Our slogan 'Proven Excellence' is no empty phrase
We can prove our excellence from our history
One can observe how we actively shaped entire industries over many years
Netzsch has always been able to adapt to radical changes in the corporate world or in the marketplace
Sometimes this also meant that we had to drastically reposition ourselves.” After the Second World War
and during the heyday of the porcelain industry
Netzsch built complete factories for the ceramic industry
“We want to transfer this historically grown adaptability into the future as well,” explains Moritz Netzsch
Important milestones in the company's history can be attributed to Erich Netzsch (1903–1990) and Thomas Netzsch (1946–2010)
Both managing directors have shaped the company and brought it forward with groundbreaking decisions
The discovery and further development of the Mohno pump under Erich Netzsch and the intensive internationalization under Thomas Netzsch are just two examples
“You can feel our Netzsch spirit at every location,” says CFO Jens Niessner
the perspective for the employees – this pairing sparks an aura that makes us competitive even in places where other companies with a high international profile are located.”
Netzsch Pumps & Systems has served markets worldwide for more than 60 years
sophisticated solutions for applications in every industry type

The fire extinguishers from the "Gebrüder Netzsch Maschinenfabrik” were a big seller
went on to develop machines for ceramic production that were also renowned for their quality
With the boom of the porcelain industry at that time in the Fichtelgebirge
the company finally concentrated entirely on the production of the ceramics industry equipment
the success story of a family-owned company began
which today spans the globe with its three business units "Pumps & Systems"
"Grinding & Dispersing" and "Analyzing & Testing" - with products such as the Mohno pump
with around 210 production and sales locations and more than 4,100 employees
the NETZSCH Group is once again headed by two brothers from Selb: Moritz and Paul Netzsch
This is one of the reasons why NETZSCH had its corporate history researched from a variety of perspectives for its 150th anniversary
Looking into the past not only substantiates values and successes
it also reveals the fit of a value proposition
"Our history provides answers as to why we have existed for so long
Our slogan 'Proven Excellence' is no empty phrase
NETZSCH has always been able to adapt to radical changes in the corporate world or in the marketplace
Sometimes this also meant that we had to drastically reposition ourselves," says Paul Netzsch
NETZSCH built complete factories for the ceramic industry
All of these developments ultimately led to NETZSCH positioning itself very successfully in the market with its "Analyzing & Testing"
"Grinding & Dispersing" and "Pumps & Systems" business units
"We want to transfer this historically grown adaptability into the future as well," explains Moritz Netzsch
CFO Jens Niessner is convinced: "You can feel our NETZSCH spirit at every location
the perspective for the employees - this pairing sparks an aura that makes us competitive even in places where other companies with a high international profile are located." The result: Niessner repeatedly experiences deja vu during employee interviews all over the world: "I often meet employees
and realize in conversation: the son or daughter now also works for us
Our spirit is not only inherited by the owner family
NETZSCH is planning extensive celebrations - including at all major international locations
The company will share the various facets of its history with its workforce

then the tournament should be a successful dress rehearsal for the highlight of the season
In the preliminary round we will meet Switzerland and Austria alongside Finland and Norway
That’s why the comparisons in Selb are very informative.”

These are some of the objects that kids of all abilities will be able to enjoy in Hainesport’s new playground
which volunteers started to build Saturday morning
Around 40 volunteers arrived at the site as early as 6:30 a.m
The playground will be accessible to children with developmental and physical disabilities
as all new playgrounds are required to be according to the Americans with Disabilities Act
is that special needs and non-special-needs children will be able to enjoy the space together
without even realizing that it is “special” at all
“They (will) have no idea that we’ve designed it so they can play together seamlessly,” Wiley said
There will be “able-bodied children and disabled together
The playground will be paved so as to be wheelchair-accessible
and the equipment is designed to be low to the ground or have ramps
Kids can get in with their wheelchair on a couch-shaped glider called a “Sway Fun” or get dizzy in a big spinner
which is particularly appealing to children with autism
but all kids will likely enjoy playing on the drums and musical scales
or spinning the colorful balls built into the wall
the accessible playground is being built next to a traditional playground
so that parents can watch over children playing in both areas at the same time
Volunteers will work through the weekend and officials hope the playground will be done by next week
Administrator-Clerk Leo Selb said that he expected there will be a ribbon-cutting ceremony on Sept
this would not become a reality unless the community got involved
They are not afraid to step up and help out
And not to mention that it’s a tremendous savings,” he said
Wiley estimated that using volunteer labor to set up the equipment will save the town around $30,000
located at the municipal complex off Marne Highway
came from the town’s open space and recreation fund
plus a $120,000 grant from the Burlington County Municipal Park Development Program
of Cherry Hill completed the initial site work to prepare a base for the equipment for $53,849
Two grandparents at the park on Saturday were particularly glad to help set up the equipment
Hainesport resident Jackie Agostini said her granddaughter Ava
She thinks Ava will enjoy the upright swings
“It’s an exciting concept and it’s in keeping with where we are in terms of understanding that children with special needs need to play right next to children that don’t have special needs,” Agostini said
brought up the idea of a new accessible playground at town meetings three years ago
Marco Agostini said he’s glad that Hainesport will be the first town in Burlington County to have a “state of the art” playground that is 100 percent compliant with ADA standards
“We want to give credit to the mayor and township committee … that have been supporting this project 100 percent,” he said
There are also plans for the nonprofit group Build Jake’s Place to construct an accessible playground in Delran
modeled after the Jake’s Place playground in Cherry Hill
Selb said that eventually all of the playgrounds in Hainesport will become completely accessible
HAINESPORT — The Township Committee accepted a bid Tuesday evening to construct an inclusive playground at the municipal complex off Marne Highway
the lone bid for the project was rejected because it was higher than the township had estimated
The committee decided to rebid the project this month without scaling back the scope
according to Township Administrator Leo Selb Jr
added to our projected cost for the actual playground
brings us to where we need to be for what we had estimated for the project
That total includes the playground equipment and other costs
The township has received a $120,000 grant from the Burlington County Municipal Park Development Program to pay for the project
The rest of the money will come from the town’s open space and recreation fund
“The bid we received was just about $20,000 less than the bid we had a couple of months ago,” Wisnosky said
referring to the rejected bid from Command Company Inc.
The canceled community-build day for the playground
The playground will include equipment that encourages sensory play and will be built next to an existing playground and tennis courts at the municipal complex
It will include swings that have a harness for use by children with disabilities
sensory equipment for children with autism
and a handicapped-accessible merry-go-round
The project represents the fifth phase of construction at the park

A Gebr Heinemann/Unimex joint venture has opened its latest “˜Travel Free’ Shopping Center at the Selb-AÅ¡ border crossing
The partnership between Prague-based Unimex Group and Hamburg-based trading company Gebr Heinemann trades as Travel Free s.r.o
The alliance described the new store as a “bargain haven”
with over 15,000 original branded items on offer
The border store is 30km from the German city of Hof
“Customers can select from a wide range of products made by well-known manufacturers
costs almost half as much as in the German national market and savings of up to -40% can be made on a pound of coffee while
at prices between €15 and €20 lower here than elsewhere
an exquisite perfume becomes the ideal gift for Christmas.”
In addition shoppers can choose from a wide assortment of clothing bearing the S
The Shopping Center is located just after the Selb border crossing
which is used every month by around 400,000 Germans to enter the Czech Republic
It also features a conveniently located service station at what the joint venture described as “irresistibly attractive” prices
customers will be able to dine in the Center’s restaurant or use the in-house casino
ABOUT THE ‘TRAVEL FREE’ CONCEPT
value-for-money shopping has been a feature at the Germany-Czech Republic border
Until 2004 shops located between the passport control posts could offer their goods free of customs and tax charges
However with the entry of the Czech Republic into the European Union in May 2004 the Travel Free concept became the German-Czech equivalent of travel retail at border crossings
Gebr Heinemann Manager for Eastern Europe Ralf Tiedt said: “Our many years of contact with brand owners and suppliers
in addition to our business relationships here in the Czech Republic
of the benefits of maintaining the popular border shops.”
As a result customers will continue to be able to take home up to 20lb of coffee
or 20 litres of spirits with an alcohol content by volume of less than 22%
When they pay staff in the shop check that the maximum of permitted export quantities (including 90 litres of wine or 110 litres of beer) are not being exceeded
Smokers also have reason for Christmas cheer – from the start of 2008
instead of the one carton of cigarettes previously allowed
they will now be permitted to buy as many as 800 cigarettes
From 1 January 2008 the Schengen agreement will apply to the Czech Republic
With the removal of the obligation to present their passports
Germans will be able to enter their neighbouring country even more quickly
Penetration rates are very high – Gebr Heinemann said that every second person crossing the Czech-German border buys something in a Travel Free Shop

28 November 2016) At this year's annual conference in Innsbruck
the Austrian Society for Allergology and Immunology (ÖGAI) awarded prizes to two researchers from MedUni Vienna for works in the field of immunology
Anna Gieras won the Clemens von Pirquet Prize and Regina Selb received a Dissertation Prize
the Austrian Society for Allerglogy and Immunology awards the Clemens von Pirquet Prize for outstanding works in the field of allergy research
the international panel of experts chose Anna Gieras from the Institute of Pathophysiology and Allergy Research at the Medical University of Vienna (currently with the Institute of Immunology
University Medical Center Hamburg-Eppendorf
She received the prize for her work entitled "IgE epitope proximity determines immune complex shape and effector cell activation capacity"
which has been published in the Journal of Allergy and Clinical Immunology (137 (5):1557-15565
studied genetics and microbiology at the University of Vienna
Her interest in allergy research was influenced by her mentor
Even while she was writing her dissertation at the Institute of Pathophysiology and Allergy Research at the Medical University of Vienna
she was heavily focussed on the molecular determinants of allergy-induced effector cell activation
She was able to continue this research project during her dissertation
demonstrating that the extent of an allergic reaction is determined to a large extent by the number and also the position of IgE epitopes on an allergen
she received a bursary under the "EMBL Interdisciplinary Postdocs" (EIPOD) programme and this enabled her to work on interdisciplinary research projects at the European Molecular Biology Laboratory (EMBL) in Hamburg
Gieras is working and teaching at the Institute of Immunology at the University Medical Center Hamburg-Eppendorf
where she is researching the effects of prenatal steroid treatment on immune system development
Regina Selb was born in Feldkirch (Vorarlberg) in 1983
She studied microbiology and genetics at the University of Vienna between 2003 and 2010 and
during her diploma project with Angela Witte at the MFPL
she researched haloalkaliphilic Archaea viruses
Between 2010 and 2015 she completed a PhD in immunology at MedUni Vienna
She wrote her thesis at the Department of Ear
Nose and Throat Diseases in an allergology working group led by Verena Niederberger-Leppin
the low affinity receptor for immunoglobulin E (IgE)
Regina Selb is currently working at the European Food Safety Authority (EFSA) in Parma
where she is writing a new European Guideline on the allergy risk assessment of genetically modified plants for foodstuffs and animal feed
