Arrangements are with Daniel-Anderson Funeral Home
1959 in Paynesville to Daniel and Juanita (Renneker) Schlangen
Together they raised five children on their farm near Lake Henry
Dale was self-employed in construction and farming all his life
the Lake Henry Lions and the Knights of Columbus
always looking for a good deal and usually doing a little PR work
Even though he had everyone’s phone number memorized
he liked driving to see if someone was home instead of calling
but he travelled every back road from Renville to Sauk Centre
Holdingford to Eden Valley (he believed they were faster)
He did take one road trip with the family to Nebraska where he sat in the back because he was the only one who didn’t get car sick
He enjoyed farming when he didn’t have to fix something
Dale was always willing to start up a skid loader or tractor to make the grandkids happy
and he enjoyed teaching young people the skills of construction
Erika (Elliott) Skogen of Ramsey; nine grandchildren
He was preceded in death by his parents; and brothers
Memorials are preferred in lieu of flowers
Mass of Christian Burial celebrating the life of Dale J. Schlangen, 65, of Lake Henry will be 12:30 p.m. on Monday, January 6, 2025 at St. Margaret’s Catholic Church in Lake Henry.\nRead More
The Echo Press immediately reached out to the county’s Public Information Officer
Anderson sent a statement to the newspaper via email on Tuesday morning
“The county coordinator serves at the pleasure of the board and employment may be terminated by the board without notice
The Douglas County Board has chosen to move in a different direction and has severed employment with Heather Schlangen.”
Douglas County commissioners appointed Schlangen to serve as the Douglas County coordinator at an August 2014 board meeting
Here is Anfinson’s response: “The key issue in a situation like this is whether the action taken by the board was in any way disciplinary
a lot of information is public under the Data Practices Act
if the board claims this move wasn't disciplinary
you are nonetheless entitled under section 13.43 to any complaints or charges lodged against the employee
You're also entitled to any agreement entered into between the board and the employee relating to the severance.”
Douglas County Attorney Chad Larson responded by saying the decision to terminate the county coordinator was not the result of a disciplinary action as contemplated under Minn
"That process would generally be followed in the event that the employee could only be terminated 'for cause,' or had a contractual relationship with the county which required a formal complaint
and consideration of disciplinary action," Larson said
then 13.43 would control and specified data would be classified as public
"the official board action taken in this matter resulted in termination of an 'at-will' employee
the county board is free to terminate an 'at-will' employee for any reason
The county provided information about when and where the decision was made to discontinue Schlangen's position:
The County Board of Commissioners met in an Emergency Special Session on Monday
with the following commissioners present: Keith Englund
employee relations — generalist; and Lenae Roeser
human resources and central services assistant
seconded by Kalina to discontinue the employment of the county coordinator director or the county coordinator director may voluntarily resign
or we shall terminate her employment as of Monday
at 9 a.m.," according to the minutes of the meeting
Anfinson said if the board insists the action wasn't disciplinary
then the disclosures required under the Data Practices Act when there is a disciplinary action don't apply — although the other information he mentioned earlier is public
such as whether any charges were lodged against Schlangen
and if there was any agreement between the board and Schlangen related to severance
The Echo Press requested that information but did not receive a response by deadline
Anfinson was skeptical about the board's actions and why no reasons were given
"I will say that it's quite remarkable the board could unanimously decide to fire the county coordinator in a four-minute meeting
without any discussion," Anfinson told the Echo Press
"It certainly invites suspicion about whether the Open Meeting Law was complied with."

where tens of millions of people now face unemployment and hunger
https://twitter.com/PndmcSrvvrsUSA/status/1247714788978933761
MintPress News spoke to a number of people on the front lines attempting to keep America fed during the worst pandemic in a century
“Needs have skyrocketed not just here but around the country,” said Eleanor Goldfield
One man who called us here at D.C. Mutual Aid to request help said that he had walked several miles the day before in order to get to a local food bank only to find that they were closed
He said he was completely out of food and didn’t understand how they could just shut down operations like that.”
“New York City is facing a crisis unlike anything we’ve seen. As the economic fallout of the coronavirus pandemic continues, more New Yorkers are facing food insecurity,” said the Food Bank for New York City
It estimates that it will have to provide 15 million meals over the next 90 days
https://twitter.com/robfike/status/1248353675598336001
“We have seen a significant increase in demand for food, about 30-40 percent higher,” said Karla Bardinas of Fulfill
formerly the FoodBank of Monmouth and Ocean Counties
These meals are on top of what we were already serving as a direct result of schools and businesses being closed and people losing their jobs.”
Workers on the frontline not only have to deal with increased demand but also the very real risk of death
from complications of the coronavirus…so of course
But we all have a commitment to feeding our neighbors who are food insecure
people need our help to put food on their tables
so we are inspired to work hard to continue our mission,” Bardinas told MintPress
Both Bardinas and Goldfield said their organizations are taking strict safety precautions in an attempt to limit the spread of COVID-19

the government has declared a generalized three-week lockdown
offering 2,000 rupees (around $26) to all citizens to get them through
But locals complain this is far from enough to sustain themselves and that the poor
“It is powerful and heavy working here right now…this is the first time I’ve been in D.C
Everywhere is crushed by the horrific failings of our oppressive capitalist system,” said Goldfield
It’s horrible to see how fragile the construct of our society is
how easily it disposes of the most marginalized
it would be far worse to ignore that reality than to see it and act upon it
I’m hopeful that this work will not only see us through this crisis but create the foundations of what is to come
The great author and activist Arundhati Roy recently wrote that the current pandemic is a portal to the future: “We can choose to walk through it
dragging the carcasses of our prejudice and hatred
And ready to fight for it.” The storm might far be over
but there is the possibility to use the crisis to build a fairer society
one where the need for food banks will be relegated to the pages of history books

International standard CIE S 026:2018 provides lighting professionals and field researchers in chronobiology with a method to characterize light exposures with respect to non-visual photoreception and responses
This standard defines five spectral sensitivity functions that describe optical radiation for its ability to stimulate each of the five α-opic retinal photoreceptor classes that contribute to the non-visual effects of light in humans via intrinsically-photosensitive retinal ganglion cells (ipRGCs)
The CIE also recently published an open-access α-opic toolbox that calculates all the quantities and ratios of the α-opic metrology in the photometric
based on either a measured (user-defined) spectrum or selected illuminants (A
For a wide variety of ecologically-valid conditions
the melanopsin-based photoreception of ipRGCs has been shown to account for the spectral sensitivity of non-visual responses
from shifting the timing of nocturnal sleep and melatonin secretion to regulating steady-state pupil diameter
Recent findings continue to confirm that the photopigment melanopsin also plays a role in visual responses
and that melanopsin-based photoreception may have a significant influence on brightness perception and aspects of spatial vision
Although knowledge concerning the extent to which rods and cones interact with ipRGCs in driving non-visual effects is still growing
a CIE position statement recently used melanopic equivalent daylight (D65) illuminance in preliminary guidance on applying “proper light at the proper time” to manipulate non-visual responses
Further guidance on this approach is awaited from the participants of the 2nd International Workshop on Circadian and Neurophysiological Photometry (in Manchester
The new α-opic metrology of CIE S 026 enables traceable measurements and a formal
quantitative specification of personal light exposures
we apply this metrology to everyday light sources including a natural daylight time series
This collection of examples suggests ways in which variations in the melanopic content of light over the day can be adopted in strategies that use light to support human health and well-being
melanopsin is the functional photopigment for one of these five photoreceptor types
(A–D) Schematic representation of the effects of light on the 24 h melatonin profile
This profile marks the circadian rhythm and the habitual sleep period
The latter is indicated by the horizontal dark rectangle
the light blue line represents the corresponding melatonin profile for an individual in 24 h dim light conditions
The red triangle indicates the time at which the core body temperature reaches its nadir at about 2 h before (habitual) wake-up time
The vertical rectangles denote a particular light exposure
(A) Light exposure in the morning advances the timing of melatonin secretion (i.e.
(B) Light exposure in the evening delays the timing of melatonin secretion
(C) Light exposure during the habitual sleep period acutely suppresses melatonin secretion
(D) Daytime light exposure strengthens subsequent nocturnal melatonin secretion
(E–H) Double-plotted actograms schematically showing patterns of the human sleep-wake (SW) cycle resulting from different light exposures
each starting with several days in 16L:8D and with light restricted on subsequent days
(E) Light restricted to 1 h in the morning on waking
(F) light restricted to 1 h in the late evening light
since the intrinsic period of the circadian rhythm in humans slightly exceeds 24 h
the timing of the SW cycle drifts later and later across days
(H) A theoretical example with sufficient light each morning and evening to entrain the SW cycle
Although the introduction concentrates on chronobiology
it should be noted that chronobiological responses are just a subset of non-visual responses to light
The non-visual metrology tools described in this paper
can also be applied to other retinal responses to ambient light
There are no ipRGCs in the central visual field
but outside this field their density falls off to a steady value
The maximum density of the ipRGCs is ~20–25 cells·mm−2
4 orders of magnitude lower than the maximum densities of the rods or cones
This loss of ipRGCs is accompanied by changes in cell morphology and an observable increase in randomness of the ipRGC distribution pattern
Traditional lighting practice primarily targets visual performance, comfort and other aspects of the visual domain, quantifying lighting designs and installations and light exposures using luminous flux (in lumens), illuminance (in lux) and other visually related quantities. These quantities describe the luminous sensation of a light source under photopic conditions [i.e., for luminances above 5 cd/m2 (76)]
Scotopic vision occurs while the eye is adapted to very low luminances (below 0.001 cd/m2)
The conversion between luminance and illuminance depends on the apparent source size measured in steradians
so general scotopic and photopic thresholds cannot be expressed in lux
Individually, photoreceptors follow the principle of univariance, meaning they cannot discriminate between a change in intensity and a change in wavelength (77). As such, the spectral sensitivities of the human luminous sensation for photopic and scotopic vision can be described by the spectral luminous efficiency functions V(λ) and V′(λ), respectively, see Figure 2A
can be photopically-weighted or scotopically-weighted by multiplying each wavelength by V(λ) or V′(λ)
lux or candela) are obtained after summing the result (which is now a photopically- or scotopically-weighted spectrum) over all wavelengths and multiplying the result by the corresponding efficacy constants (Km and K′m
By definition, monochromatic radiation with a frequency of 540 × 1012 Hz, (which corresponds to the wavelength 555 nm in standard air) has a luminous efficacy of 683 lm/W (78)
Since the V(λ) function reaches its peak value at 555 nm
this is where the maximum luminous efficiency for photopic vision (denoted by constant Km) equals 683 lm/W
The maximum luminous efficiency for scotopic vision (denoted by constant K′m) equals 1,700 lm/W
which follows from the relationship Km·V(555 nm) = K′m·V′(555 nm)
The ratio of the luminous output (of a source) as evaluated using the scotopic efficiency function to the luminous output evaluated using the photopic efficiency function is known as the S/P ratio
The S/P ratio is a characteristic of the spectral distribution of the light
equals 1 for monochromatic radiation with a frequency of 540 × 1012 Hz
An S/P ratio above 1 denotes that a light source is more activating to rods per (photopic) lumen than 1 lumen of monochromatic light at 555 nm
Mesopic vision occurs while the eye is adapted to light levels that are in between photopic and scotopic conditions. In this range, i.e., in the mesopic regime, the combined action of rods and cones defines the human visual response. However, ipRGCs are implicated in retinal adaptation (79) and may be involved in the regulation of mesopic and photopic visual sensitivity (80)
the relevance of melanopsin-based photoreception for brightness perception beyond laboratory settings is not yet settled and merits further investigation
the melanopsin-based photoreception of ipRGCs constitutes an important driver of non-visual responses
many lighting designers already draw on a wide understanding of the visual
architectural and psychological aspects of light and lighting
Awareness amongst lighting professionals is increasing that next to cone-dominated metrics such as correlated color temperature (CCT)
there is a need to consider melanopsin-based photoreception in specifications
All these metrics are useful tools for quantifying or comparing individual aspects within a lighting scheme
but they cannot replace an experienced designer's overall appreciation of the interplay between the diverse effects of light
NIF photoreception relates to the light arriving at the eyes from all directions
This requires recommendations framed in terms of light arriving at eye level—e.g.
measured normal to the visual axis in the vertical plane—rather than with reference to the light falling on the horizontal plane
This new International Standard defines spectral sensitivity functions
quantities and metrics to describe optical radiation for its ability to stimulate each of the five retinal photoreceptor classes that
can contribute to the non-visual effects and functions of light in humans
to describe the cone and rod action spectra
Figure 2A shows the five spectral weighting functions or action spectra, sα(λ), for the five retinal photoreceptor classes: S cone, M cone, L cone, rhodopsin and melanopsin-encoded photoreception of ipRGCs as defined in CIE S 026. For each of these five (α-opic) photoreceptors, an α-opic irradiance can be calculated from the spectral irradiance, Ee,λ, of a (test) light source, see Table 1
The α-opic irradiance of a test light divided by its illuminance
defines its α-opic efficacy of luminous radiation (α-opic ELR)
The ratio of this α-opic ELR to the α-opic ELR of standard daylight (D65) defines the α-opic daylight (D65) efficacy ratio (α-opic DER) of the test light
Table 1. Glossary of α-opic metrology (12), where sα(λ) refer to the α-opic action spectra shown in Figure 2A
Kα,v is the “α-opic stimulus per lumen,” Kα,v calculated for D65 (i.e.
Kα,vD65) is a normalization constant
There are two ways to calculate the α-opic DER: α-opic DER = α-opic ELR / α-opic ELR for D65 = α-opic EDI / illuminance
Since daylight is a naturally occurring stimulus under which we evolved, it is an interesting and relevant point of reference to evaluate and express the properties of human light conditions within the built environment. The CIE standard illuminant D65 is adopted as the reference illuminant in CIE S 026 (2018) to express each of the five α-opic irradiances as a photometric equivalent quantity
These quantities are the five α-opic equivalent daylight (D65) illuminances (α-opic EDIs)
Each α-opic EDI is expressed in lx and corresponds to the illuminance of D65 radiation that is required to provide an equal α-opic irradiance as the test light
The term “test light” used here refers to the light being considered
to differentiate it from the reference illuminant
The photometric equivalent concept adopted in S 026 is not restricted to illuminance (unit lx), and luminance (unit cd/m2). It can also be applied to other quantities such as light exposure (unit lx·h), luminous energy (unit lm·s), and luminous intensity (unit cd)
Returning to CIE S 026, when describing the spectral properties of a test light, the ratio of the α-opic EDI of a test light to its illuminance defines the α-opic DER of the test light, see Table 1
the melanopic DER represents the ratio of the melanopic flux (“M”) per photopic luminous flux (“P”) of a test light
and this dimensionless quantity can usefully be thought of as the new “M/P ratio.” By definition
this ratio is normalized to 1 for the reference illuminant D65
The S/P ratio is an established lighting metric
It equals 1 for monochromatic radiation of 555 nm
as the S/P ratio effectively uses radiation of 555 nm as its normalizing reference illuminant
the test light has the same activating effect on ipRGCs as 30 lx of radiation conforming to the spectrum of D65 daylight
a scotopic illuminance of 30 lx indicates that the test light has the same effect on rods as 30 lx of radiation at 555 nm
There are three different mainstream metrological approaches for quantifying visible optical radiation:
• radiometry based on spectral energy
• radiometry based on spectral count of photons
• photometry based on spectral luminous efficiency function for photopic vision
Km (or V′(λ) and Km′ for scotopic vision)
radiometry is described as “the field of metrology related to the physical measurement of the properties of electromagnetic radiation
including visible light.” Radiometric quantities can be unweighted
but photobiological quantities are typically weighted according to a suitable action spectrum that describes the relative efficiency of radiation as a function of wavelength in producing an effect
Figure 3 illustrates the deep connections between these three metrological approaches
etc.) in the photometric system has the analogs photopically-weighted (irradiance
radiance) in the radiometric system and the analogs photopically-weighted photon (irradiance
sr−1·m−2·s−1)
For melanopic quantities—with exactly the same units—the respective quantities are [melanopic EDI
melanopic equivalent daylight (D65) luminous flux
melanopic equivalent daylight (D65) luminance]
radiance) and melanopic photon (irradiance
for the other four α-opic quantities
melanopic equivalent daylight (D65) luminance can be abbreviated to melanopic EDL
The three approaches to metrology and the α-opic quantities corresponding to these approaches
To calculate α-opic quantities in the radiometric, photon and photometric systems, and convert from one system to another, CIE has published an interactive ExcelTM spreadsheet, the “CIE S 026 Toolbox” (90). Access to the toolbox is free on the CIE website [doi: 10.25039/S026.2018.TB]
and also an introductory video and a user guide are provided
The toolbox features include weighting functions
spectral weighting charts and a concise glossary
The CIE has proposed “integrative lighting” to be the official term for lighting that is specifically intended to integrate visual and non-visual effects, producing physiological and psychological effects on humans that are reflected in scientific evidence (59, 92)
In the context of this promising new approach
we reconsider the light that people are exposed to in their daily lives
To investigate and characterize potential light exposures in relation to non-visual responses
a number of measurements of familiar sources of light were made
where possible re-using information from previous investigations
The α-opic toolbox was used to evaluate the absolute and relative melanopic content of these sources in more detail
subject to the potential limitations of the melanopic model for predicting NIF responses to light (see Introduction)
the information provides useful context and further evidence for advice relating to light and health
All the spectral data were measured using equipment sets subject to secondary calibrations
and traceable to national standards performed
and maintained in-house (Public Health England
The data were checked against comparable alternative measurements of the same sources
Spectral equipment sets consisted of TE-cooled spectroradiometers (BW Tek
coupled via optical fibers (Newport Spectra-Physics Ltd.
Daylight characteristics analyzed relate to a clear day (29 May 2020) and a cloudy day (18 June 2020)
and are based on global spectral irradiance data from a solar monitoring laboratory at (51.575° N
measured in the horizontal plane at 5-min intervals using in-house acquisition software (Public Health England
The photographic fisheye image taken at 04:25 on 29 May 2020 in Figure 5B is part of a parallel series

The simplified spectral emissions of a candle were modeled as arising from a Planckian radiator with a color temperature of ~1,930 K (94)
the CCT falls rapidly in the hours either side of dawn
The minimum CCT occurs ~1 h either after dawn or before sunset
with a small increase in CCT to a local maximum at approximately solar noon
Atmospheric conditions may give rise to asymmetry in the spectral characteristics on either side of solar noon
In the next section we will compare this to white LED lighting
a lower melanopic DER may be appropriate at night and within spaces designed to be restful
whereas in active workplaces a higher melanopic DER and an elevated illuminance may engender a healthier daytime environment
There are two approaches for performing calculations available in the toolbox
The first is a simplified approach using the spectra from the five built-in standard illuminants (A
The second approach requires the user to enter the actual spectral data of the test light in consideration
These two approaches are chosen to illustrate why using the simplified approach (i.e.
generalizing results from standardized spectral distributions) will not always be appropriate
As the screen subtends an angle of approximately a 5th of a steradian at a viewing distance of 150 mm
melanopic EDI and melanopic photon irradiance can be obtained as follows:
we may not be able to rely on the above estimates
We assumed that the spectrum of the mobile phone conforms to LED-B3
as the spectrum from mobile phones may have a higher blue content and
is produced by three or more single color LEDs rather than by using a blue LED in combination with a yellow phosphor
In order to replace the above estimates with accurate figures
When using the toolbox with the spectral irradiance data collected for the selected LED screen [ID 13, (91)], the toolbox output sheet (see Figure 4B) gives the following results:
This spectral analysis shows that the simplified approach with the assumption that the phone's light emission conforms to LED-B3 resulted in underestimating the melanopic irradiance and EDI by almost 30%
Exposure at 150 mm distance from a phone screen (at full white power) is a plausible worst-case scenario for mobile screen use in children and young adults
but it is unlikely that the screen would be used in its brightest setting only
The mix of light and dark within the images displayed on the screen will reduce the spatially-averaged screen brightness as well as the time-averaged melanopic EDI measured at the user's eye
The brightness and the blue emissions may also be reduced in power in the evening using a suitable app
holding the phone at a further distance reduces the average melanopic EDI incident at the eye
by reducing the “visual” field occupied by the screen
these findings provide inconclusive evidence whether the melatonin suppression induced by mobile phone light emissions in the evening are at levels that raise practical concerns
the possibility still remains that prolonged evening use of indoor electric lighting may result in light exposures that are relevant for melatonin suppression

Daily variations in the light environment are important for sleep
The knowledge base concerning the contributions and interactions of retinal photoreceptors in driving non-visual effects is becoming more mature
Although the science is by no means complete
measures of the environment expressed in terms of melanopic EDI are now thought to have ecological validity
New recommendations for future building and lighting standards are therefore expected to incorporate both minimum thresholds for daytime melanopic EDI and maximum thresholds for evening melanopic EDI
These recommendations should be carefully integrated with the visual components within existing lighting codes
One way of limiting evening melanopic EDI would be by recommending dimmer lighting
and this is more effective when simultaneously lowering melanopic DERs (i.e.
Another recommendation could be to strive for near darkness wherever people are expected to sleep at night
partly to support this expected shift in lighting practice
and partly to enable researchers to expand the evidence base for future lighting standards
Figure 5D shows that the melanopic DER for daylight on a clear day is significantly greater than the melanopic DER within a recent sample of white LED lighting with a range of CCTs. This supports the viewpoint that the LEDs sampled are relatively inefficient at producing melanopic light for a given combination of CCT and luminous flux, in agreement with others (97, 98)
might be considered a beneficial characteristic for the daytime indoor environment
Daylight entry within the built environment is a good way to achieve this
If the aim is to minimize melanopic light exposures, the lighting used at night for navigation and perceptions of safety should be restricted to lower M/P ratios. Increased daytime light exposures can reduce the adverse effects of evening light (39–46)
and daytime light exposure may be as important as avoiding bright light before bedtime
indoor electric lighting could reproduce the melanopic light exposures (and other facets) of the outdoor environment
although this entails greatly increased indoor illuminances
energy-efficient source of melanopic-rich light
and public health policies should encourage a daytime (natural) light-seeking lifestyle
especially during the first morning hours after bed and starting from the very first days after birth

of a single photon depends on Planck's constant
and the refractive index of the medium (nair

the corresponding radiometric energy is Ee = Np·h·c/λ·nair
When converting action spectra from the photon system to the radiometric energy system
once the adjustment has been applied at every wavelength
the entire action spectrum must also be renormalized so that its new maximum value is equal to 1

Stearns County dairy farms made up 22 percent of the herds highlighted by the state for top-quality milk this year
But the top producer on the Department of Agriculture's newest list
sold its cows last November after four years in the red.
the Minnesota Department of Agriculture has celebrated farms with the lowest somatic cell counts
Lower counts are better for cheese production and shelf life for bottled milk
Daniel and Jolene Schlangen have kept low somatic cell counts and been recognized for their efforts by the state and dairy cooperative First District Association for 15 years, Daniel Schlangen said.They were at the top of the state list released this month.
"We just loved what we did," Schlangen said Thursday
"We were extremely proud of what we were doing."
The couple sold off their herd late last year — about 170 red and white Holsteins
he said. "Four consecutive years of complete red ink
It's a tough time to be a farmer in the U.S

Lower somatic cell counts make milk more valuable to producers
according to a Wednesday press release from the Department of Agriculture.
"It's especially important to recognize these dairy farmers at a time when milk prices are low and the dairy industry is struggling," said Department Commissioner Dave Frederickson in the release
these producers have worked hard to improve the management of their herds to reach this level of excellence."
RELATED: Small dairy, big tech: Melrose farm has barn of the future
Minnesota groups have worked with dairy farmers for 15 years to lower somatic cell counts in an initiative called Quality Count$. It's not a matter of food safety, but quality, and relates to a cow's resistance to mastitis, inflammation of the mammary glands and udder tissue
There's been a big drop in those cell counts
as Minnesota farmers have worked to meet international standards from the European Union
"I take my hat off to those farms that are in the top 100
It's quite an honor," Fall said of the list of farms with the lowest counts
The co-op tests producers' somatic cell counts upon delivery of the milk and average the counts for the state.
"(The Schlangen's) were always our number one in First District," Fall said
"They managed their cell counts like a hawk."
The couple bought the farm from Daniel Schlangen's mother 19 years ago
His father brought in dairy cows 12 years prior to that
And four years ago he and his wife invested and added on to their barn.
"You lay it all on the line as a small farmer," he said
and they are losing $5 on every 100 pounds of milk, Schlangen said. "It makes a grown man lay down and cry

Schlangen will lead one of the company’s three regional sales divisions and report to Chief Customer Officer Steve Dietz
Schlangen joined UNFI in 2015 as a member of Supervalu’s financial analyst team
he has held a range of leadership roles of increasing responsibility
helping to generate customer profitability and supporting strategic investments across wholesale and fresh
“JJ is a collaborative leader who aligns his teams against both strategy and processes that lead to positive results for customers,” noted Dietz
“He has been a tremendous partner to me over the last several years as we have reimagined our team to focus on helping our retail customers grow
however they are positioned in the market.”
Schlangen’s most recent position was that of VP of sales strategy and operations
he helped develop and implement new sales training and processes
enabling the team to close significant new business
and contributed significantly to the creation of a superior sales and customer support organization
Schlangen earned a bachelor’s degree from the University of North Dakota and also graduated from the University of Southern California’s Food Industry Management Program
Last year, as it worked to better align leadership teams and resources to drive its customer-centric strategy and transformation agenda, UNFI promoted Erin Horvath to the role of COO
while Louis Martin became president of wholesale
Beth Schlangen met the Benton County commissioner she hoped to replace when she knocked on his door while campaigning.
"She knocked on my door and asked for my vote

Schlangen will be the third woman to serve on the Benton County board in its 170-year history
Elaine Fleck was the first female commissioner in the county, according to the Benton County Historical Society
Fleck served from 1989 to 1992 and again in 1993 for two years
according to the Benton County administrator's office
Alice Trushenski
held her seat from 1993 to 2001. There hasn't been a woman on the board for nearly 20 years
Schlangen said she feels "positive" about bringing "a woman's voice … a woman's perspective" to the board.
Schlangen was in the first graduating class at Apollo High School and attended St
She worked as a nurse before retiring and lives in St
Cloud with one of her four daughters and her daughter's family. Her eldest daughter died about a year ago
Schlangen also has 11 grandchildren between the ages of 5 and 25
Schlangen serves as treasurer for the Minnesota Federation of Republican Women and has been on the boards of local Republican Party units. She's been through two candidate training programs, and she ran for St. Cloud School board in 2018 and lost.
She considered another bid for the school board this year before deciding to run for the Benton County board.

She plans to be fiscally responsible and ensure residents get the services they need
she said. Some family and friends had some problems with county services.
"I just want to make sure they're doing their jobs right and helping the people
so that everybody has a good outcome," Schlangen said.
Schlangen is not the only new member joining the board
Two commissioners — Warren Peschl and Spencer Buerkle — chose not to run for re-election

GRANITE FALLS — A former law enforcement officer will serve 15 days in jail and two years of probation
as the result of a felony conviction for reckless discharge of a firearm in a municipality
pleaded guilty May 5 to reckless discharge of a firearm in a municipality as part of an agreement in which a charge of domestic assault was dismissed
An amended sentencing order issued by the District Court in Yellow Medicine County on July 12 requires that he serve 15 days in jail with credit for four days served and probation for two years
and becomes a misdemeanor conviction on successful completion of probation
The Minnesota Board of Peace Officer Standards and Training last week completed the revocation of the defendant’s peace officer license following his felony conviction
According to information from Erik Misselt
the felony conviction stands regardless of the stay of imposition
meaning the license cannot be reinstated whether or not Schlangen successfully meets the requirements of his probation
The Minnesota Board of Peace Officer Standards and Training records show that Schlangen's license was issued in October 2014 and he had been employed during his law enforcement career with the Kanabec County and Isanti County sheriff’s offices
the Belgrade-Brooten Police Department and Upper Sioux Tribal Community Police
Schlangen was not on duty as a tribal police officer at the time of the incident for which he was charged
according to the special prosecutor for the case
Schlangen was arrested at a residence in Granite Falls shortly after 11 p.m
5 by a police officer responding to a report that the defendant had discharged a firearm in the house
The defendant and his girlfriend had been at Prairie’s Edge Casino Resort and had received a sober ride home from his parents due to being intoxicated
and the complaint alleged that Schlangen pushed the female in the house
The complaint stated that Schlangen went to the basement of the house and discharged a firearm
it was discharged,” the defendant later told a police officer after initially not answering questions about whether he fired a firearm
In an order for protection sought by the woman
she stated that he threatened suicide before going to the basement of the home and discharging a Glock handgun

Steve married Cheryl and they purchased the farm near Albany where they raised their children and established a long history of conservation work that most recently has included cover crops
The Schlangens worked with the Stearns County Soil & Water Conservation District and Waite Park Natural Resources Conservation ServiceField Office
The Schlangens have been named the Stearns County SWCD 2021 Outstanding Conservationists for Stearns County in recognition of their work to protect the area's soil and water
“Being recognized for continuing to improve our land and our story every day is quite the honor,” said Steve
“Each person has a great story to tell and should be continually improving that story every day
Be open-minded about the possibility of conservation practices and talk with other landowners and farmers to hear about their experiences while continuing to share your story.”
The Schlangens will be recognized in December at the annual convention of the Minnesota Association of Soil and Water Conservation Districts (MASWCD) in Bloomington.
The Schlangens milk 60 Holsteins with a Lely robotic milker and raise their own feed on 200 acres of corn
With funding assistance from NRCS’s Environmental Quality Incentives Program (EQIP)
the Schlangens built a manure-stacking slab that allows them to store manure and use it to apply nutrients where and when they're needed.
They also work with a Certified Crop Adviser to determine nutrient needs and conduct grid soil sampling to help select the fields needing additional or minimal nutrients
The Schlangens have participated in the NRCS Conservation Stewardship Program in 2005
the Schlangens became water-quality certified through the Minnesota Agricultural Water Quality Certification Program
which provided a whole-farm review of their operation to see where they could improve conservation efforts
“We want to make sure that the land will be here for the next generation,” said Steve
“By implementing conservation practices on our farm
we are doing the most we can to contribute to ensuring our land is here for generations and that we have clean
The Schlangens dairy farm is in the Backes Lake subwatershed
Water from their farm eventually flows into the Sauk River and then to the Mississippi River
affecting people hundreds of miles away
“The Schlangens have set an excellent example of what it means to be environmentally sound stewards of the land in Stearns County,” said Dennis Fuchs
Stearns County SWCD District Administrator
“They are open-minded on trying new ways to improve their land and serve as role models for neighboring farmers not only in the area but throughout the county with Steve’s involvement in the agricultural community.”

These parks are home to 21 species of reptiles
you may hear scuffling in the dry leaves as a southern alligator lizard goes after an insect
or see a male western fence lizard doing push-up motions on a rock – displaying its blue underside as a warning to other males and an attractant to females
if you are hiking along a stream at lower elevations
watch for a western pond turtle basking on a rock
Keep your eyes open for these cold-blooded creatures: they are fascinating to watch and learn about
Fourteen of the parks' reptile species are snakes
You can get a complete checklist by visiting the NPSpecies tool below
While many fear the venomous western rattlesnake that inhabits these parks
most rattlesnake bites of people occur when the snake is being harassed or handled inappropriately
It is important to take precautions when hiking in areas where you may encounter a rattlesnake
such as avoiding tall grasses or shrubby areas where visibility is poor
and being ready to step back if you do encounter a rattlesnake
Give it space and the snake will leave you alone
It is always a good idea to hike with awareness
Some types of non-venomous snakes mimic rattlesnakes
in order to frighten away potential predators
the gopher snake does a convincing imitation of a rattlesnake
a gopher snake will flatten its head (to make it look bigger like a rattlesnake)
While gopher snakes can ward off many threats this way
a skilled observer will notice that the gopher snakes have no rattles
their eye pupils are round compared to the vertical “cat-like” pupils of rattlesnakes
and rattlesnakes have heat-sensing pits between their nostrils and their eyes
When you encounter a snake or any other wild animal – watch from a safe distance; do not handle
or threaten it; and enjoy learning about its behavior
these turtles are typically found in low gradient pool habitat hiding under banks
but the terrestrial environment is largely important for nesting
Western pond turtles primarily feed in water
Western pond turtles are California’s only widespread native turtle
Although their common name implies residence of lakes and ponds
these habitats are rare throughout their range in the Sierra Nevada
where they inhabit streams ranging up to 5000 feet in elevation
Western pond turtles are a California Species of Special Concern
Threats include non-native invasive species such as bullfrogs and trout
contaminants such as pesticides and mercury
and climate-related stress such as drought and warming temperatures

Former Benton County Commissioner Dick Soyka and a former Sauk Rapids City Council member Jared Gapinski will compete to represent a Sauk Rapids-centered district.
Scott Johnson, a farmer and school bus driver, and Christopher Winkelman, a store manager and farmer, will be on Foley-area ballots in competition for District 1 seat.
Bauerly has served on the board for two terms. Schlangen ran for the St. Cloud school board in 2018 and lost.
Bauerly, 67, lives in rural Sauk Rapids and farms corn and soybeans. He has lived in the county all but two years of his life, Bauerly said. He started farming full time in 2007 after working in the construction and concrete business, including a time as president of Bauerly Brothers and Knife River

She's also done paperwork for a trucking business in her family
Schlangen is running for county board to address homelessness
she said. "We still have problems with homelessness."
Economic development is a top issue in the race.
The east side of St. Cloud is undeveloped and run down
Bauerly expects more economic development in coming years at the business park near St
and may welcome more private aircraft.

Erik Schlangen is testing new road materials in the Netherlands
The material can heal itself through induction heating
Erik Schlangen has some problems with the current asphalt that makes up most of our roads
He says that the roads create lots of noise in populated cities where people live near heavy traffic areas
On rainy days there is a great deal of splashing when cars drive across them
His solution is to use a porous asphalt for road construction
Porous roads would allow water to drain through the surfaces
running to the side of the road or routed into collection devices
Noise would disappear into the surface due to its geometry
There are also disadvantages to a porous asphalt surface
Graveling is the main problem faced by the roads
loss of driver control and projectiles thrust into windshields
cutting small pieces of the material and inserting it into the asphalt mix
Induction heating the mixture allows the steel wool amalgam to seep into the microcracks and create a stronger product
The Dutch government took interest in Schlangen’s project and donated four hundred meters of the A58 motorway for road testing
Samples from the road were tested in the lab to find the effects of aging
Schlangen estimates that the large healing machine should go over each road every four years to double the surface life of the road
This TED talk is bookended by a demonstration where Erik takes a chunk of asphalt
breaks it with a hammer and then reassembles the pieces and placing them in a microwave
The demonstration is great and Schlangen is a very engaging and humorous speaker

called Anderson's report "an impressive professional marketing brochure
a thorough and diligent review of the publicly available facts
and it is highly misleading and irresponsible."
Among the sexual abuse survivors who spoke at Wednesday’s news conference in Chicago was Cynthia Nash Yesko
a former Springfield resident who has a private practice in mental health counseling in Evanston
Yesko and three others filed a lawsuit against every diocese in Illinois for an alleged ongoing scheme to cover up sexual assault by priests
claimed that Yunker “engaged in unpermitted sexual contact” when she was 4 to 7 years old
approximately from 1972 to 1975 in Springfield
Yesko also alleged she was abused by Schlangen
which formerly stood at Eighth Street and Enos Avenue and served the Lithuanian community in Springfield
Peter and Paul stood in the 400 block of North Sixth Street
“This is a very profound day for me,” Yesko said Wednesday
Yesko said she came forward with the abuse information in 2006 because she discovered that Schlangen was still ministering as a priest at parishes in Quincy and Mendon
I was sitting in front of the diocese’s officials telling my story,” said Yesko
“Parents deserved to know (that) he was in a parish with children.”
Yesko said she never got a chance to meet with then-Bishop George Lucas
who left Springfield in 2009 to become the archbishop of Omaha
The allegations involving Yunker and Schlangen
When the diocese was made aware of the allegations
diocesan officials reported it to civil authorities and no charges were brought
the Diocesan Review Board — comprised of predominantly lay people not employed by the diocese with professional backgrounds in areas such as state and local law enforcement
and psychology and a victim and survivor of clergy abuse — reviewed the allegations and did not find them credible
"then the clock ticks and the statute of limitations runs out
And when someone like (Cynthia) Yesko makes a report of something that happened 35 or more years ago
Top officials more often than not choose not to believe the reporter
especially if it’s one survivor coming forward."
A lawsuit was filed against Niebrugge in 2004
There were no records of allegations of abuse by Martinez during his short stay in Decatur
No priests who are credibly accused in the Springfield diocese are in active ministry
BishopAccountability.org had listed another priest for the Springfield diocese
a Franciscan who worked at Quincy College in the early 1990s
Neither The Anderson Report nor the diocese named Downey
the diocese and Bishop Thomas John Paprocki professed "profound sadness and deep sorrow for the shameful wrongs and evils perpetrated during a dark chapter in our Church history where innocent believers were abused at the hands of some clergy
The extreme hurt some of our clergy caused decades ago is a disgrace
and it grieves all of us to see the suffering these sins have caused
"The Diocese of Springfield pledges continued efforts to bring healing to the victims and survivors of this evil."
The diocese has encouraged anyone with new information about any instance of abuse to call the Illinois Department of Children and Family Services Child Abuse Hotline at 1(800)-25-ABUSE and the Diocese’s Child Abuse Reporting and Investigation number at (217) 321-1155
the Anderson report includes about 400 priests and lay people who at one time served in parishes or schools or otherwise worked in the state
with accusations spanning more than a half-century
That number far exceeds the roughly 200 priests who have already been publicly identified by the six dioceses
the new report cites a much smaller number than the 690 priests that then-Illinois Attorney General Lisa Madigan said her office identified in its own investigation last year into priest sex abuse
Madigan began looking into priest sexual abuse after a report in Pennsylvania revealed widespread abuse and cover-ups not before known
Madigan's preliminary report was critical of the Illinois dioceses' handling of abuse allegations
saying their investigations were sometimes flawed and lacked transparency
but her office did not release a full list of accused priests
issued a statement before he took office in January saying he remained committed to continuing the probe
His office has not released further information on the inquiry

— Steve Schlangen makes an effort to share his sustainability practices
dairy farmer says he is “just trying to find ways to encourage other farmers … to try things that might work for them.”
“Their enthusiasm for sharing ideas and results with others has earned them a national reputation as leaders in regenerative agriculture,” U.S
Dairy said in its announcement of the awards
Some of the sustainability practices at Schlangen Dairy Farm include adding a manure stacking slab to help better manage manure use
“We had issues with getting it applied at the right time and right the place,” Steve Schlangen said
they don’t have to worry about nutrients from the manure leaching out
“We can wait until the time is right after harvest and can put it on and work it in,” he said
Injecting liquid manure also has made the farm more efficient
using a hydraulic system to control the flow
we didn’t do much tillage at all except for the manure injection,” Schlangen said
That saves time and fuel over the spreading manure and then having to work it in
Dairy says the Schlangens can count more than 30 conservation practices that also include LED lighting
Schlangen Dairy Farm has been operating since 1986 near Albany
where they have about 60 cows and farm about 200 acres
Steve Schlangen is the current chairman of the board of Associated Milk Producers Inc.
He also is part of the Headwaters Agriculture Sustainability Partnership
a central Minnesota group that tries to find sustainability practices that also enrich farm operations
including a return on investment case study of 11 Stearns County farms
He said the emphasis on carbon storage is something dairy farmers need to find a way to capitalize on
Schlangen said he understands that not every sustainability practice works at every farm but “everyone could do something

Luc Schlangen has been awarded the prestigious Wyszecki Gold Pin Award by the International Commission on Illumination (CIE)
The award is a recognition of his contribution to fundamental research in the domain of light and illumination
Schlangen's research revolves around the development and advancement of a revolutionary methodology for quantifying light
light has a profound influence on a myriad of biological processes crucial for overall well-being
circadian rhythms and cognitive functioning
Schlangen's research focusses on the impact of a specific wavelength range of light
particularly the shorter-wavelengths around 480nm
which powerfully activate a specialized photoreceptor housing the vital photopigment melanopsin within the eye
acknowledging the collaborative efforts that made this achievement possible
He emphasized the significance of the award as a token of appreciation from the global community of colleagues and experts he has had the privilege to collaborate with over the years
the Wyszecki Gold Pin Award entitles Schlangen to a lifetime of complimentary access to all activities and publications associated with the CIE
further solidifying his standing as a luminary in the field
