Thousands of essential workers and community members are taking part in a Week of Action in the Twin Cities to fight for a host of social demands they hope will build worker power and strengthen communities They are calling for better union contracts and a labor standards advisory board The alignment of unions, workers’ centers and community organizations, and the broad scope of their aims, is being heralded as a model of social movement unionism which emanates from more than a decade of organizing and movement building March 2 saw a kickoff event and also marked the deadline that many of these groups set to see action on the issues they are fighting for.  Several unions—representing janitors and educators who have all been working without contracts—are striking or planning to strike and holding picket lines and rallies at their workplaces thousands of janitors with SEIU Local 26 began a three-day unfair labor practice (ULP) strike in downtown Minneapolis Property workers with Local 26 are also on a ULP strike against FirstService Residential Many of these workers on strike filled a conference room to capacity for a listening session with the Minneapolis City Council on a proposed ordinance to create a cross-sectoral Labor Standards Advisory Board Workers say the board will give them a voice in their workplaces and opportunities for businesses and workers to come together to solve problems.  Michael Rubke is an overnight building attendant at FirstService Residential who is on strike today He handed Minneapolis city council members a petition with 150 property workers’ signatures “It’s difficult to talk to a company that doesn’t want to listen to you they wave their hands at us and shoo us away,” he says not just for the people in my company but the working class in general.” Maria Palacios testified alongside her daughter Jaqueline Flores Both are members of Centro de Trabajadores Unidos en La Lucha (CTUL) a worker-led group that primarily organizes in Latino communities “There are often times when we are fired and we don’t get the dignity of an explanation,” says Palacios in Spanish through a translator who was holding her baby close in a fuzzy blanket also spoke about the need for a labor standards board She was fired by her employer after giving birth “They didn’t give an explanation; they just gave me a piece of paper and said I was terminated,” says Flores the executive vice president of SEIU International also gave last-minute testimony after flying in from California to see what’s going down in Minneapolis “How is it right in 2024 that my sister gets pregnant and is fired from her job nurses with SEIU Healthcare Minnesota & Iowa will begin a one-day ULP strike across the Twin Cities construction workers with CTUL will march to urge developers to sign on to a worker-driven social responsibility model Essential workers at the front lines of industries who have faced pay cuts and heavy workloads before and during the pandemic are utilizing a moment of expired contracts across multiple sectors to escalate their fights at the same time This kind of cross-sectoral organizing is unique in the United States and has been in the works for more than a decade is an overnight building attendant with FirstService Residential He rallies with workers on strike across the Twin Cities ahead of testifying at a Minneapolis City Council listening session on a proposed ordinance for a Labor Standards Advisory Board he is constantly available for whatever emergency arises “I have been told by the residents,” he says “that I work for that they greatly appreciate the fact that I’m there holding her sleeping baby close underneath a fuzzy Winnie the Pooh blanket testified at the listening session alongside her mother Maria Palacios who works at the Amazon warehouse in Brooklyn Park Minneapolis City Council member Aisha Chughtai who represents Ward 10 and is a former organizer with SEIU is one of the authors of the proposed ordinance for a Labor Standards Advisory Board this ordinance is a way for the local government to support workers in its goal of revitalizing downtown Minneapolis who represents District 8 and the city of Duluth and leads the Senate’s Labor Committee spoke to workers at a rally outside of Ameriprise Financial headquarters in Minneapolis before workers led a march downtown “Don’t let these bosses tell you that they can’t meet your demands “These are some of the wealthiest corporations on the planet You deserve to have your most basic needs met.” Unions in Minnesota began aligning with community groups over a decade ago holding weeks of action to build solidarity and worker power across sectors The current convergence strengthened with a launch event inin October 2023 workers are fighting for and winning contracts that improve their conditions and help meet the needs of the broader community As government and business interests seek to “revitalize” downtown Minneapolis essential workers like janitors who are tasked with cleaning offices and stores are making their voices heard in economic recovery efforts Around 4,000 janitors walked off the job on Monday to participate in a three-day unfair labor practice strike against their employers who are contracted by some of the wealthiest companies  César Mendez and José Carran are janitorial workers on strike with SEIU Local 26 hoping to win benefits like retirement pensions and paid holidays Carran has worked cleaning Target stores for the past 24 years two-thirds of its members have zero dollars in their savings after decades of work.  Staked into the ground in front of the Ameriprise office building in downtown Minneapolis are picket signs displaying statements that describe janitors’ economic realities The workers represented by SEIU Local 26 are on a three-day ULP strike against companies like Ameriprise Financial that provide wealth management and retirement for clients while the janitors who provide essential work cleaning company headquarters lack such protections Nursing home workers rally at state capitol Agnes Cooper is a nursing home worker at Saint Therese Senior Living in New Hope Nursing home workers held a 24-hour unfair labor practice strike on Tuesday to demand a $25 minimum wage Cooper would also like to see some paid vacation time we dance!” chant nursing home workers as they bust some moves on the state Capitol steps Nursing home workers across the state have been facing low pay and understaffing leading to higher workloads and longer hours Nessa Higgins is a member of both SEIU Healthcare Minnesota & Iowa and UFCW Local 663 and has worked as a certified nursing assistant a trained medication aide and a culinary worker “I’ve been in the field 25 years and don’t have a retirement plan because they don’t pay me enough,” she says your back aching and you’re working a double shift; you gotta get up the next day and be there at 6:30 Yet people standing behind desks are getting bonuses.” Nurses with the Minnesota Nurses Association (MNA) showed up to support workers on strike Shiori Konda-Muhammad is the first vice president of MNA and has worked as a cardiovascular intensive care unit nurse at North Memorial Health in Robbinsdale many patients move to rehabilitation or longterm care and our working conditions got exponentially worse,” she says “We need safe and quality care in nursing homes so that patients don’t bounce back to the hospital.” “The work that people do to keep our offices clean and open Minnesota doesn’t work,” says State Senator Erin Murphy (D-Minn.) a registered nurse and former nursing home worker JW Moore III works as a custodian at Metro State University and is on his second day of the three-day strike by janitors with SEIU Local 26 rallying with coworkers and nursing home workers also on strike it’s too expensive just to buy ingredients to make a sandwich,” he says Workers with UFCW Local 663 from Estates at Chateau and Villas at Bryn Mawr were also on strike A delegation of Brainerd Lakes area grocery store workers who have been working without a contract for 94 days (as of Tuesday March 5) and went on strike for five days over the Christmas holiday a front-end manager at the Pequot Lakes Supervalu general merchandise and pharmacy and runs gas pumps She has been granted “special project union representation” by her union “I believe in fighting for everybody,” she says workers attending the unions’ week-long leadership school headed inside to fill the Capitol rotunda where the Minnesota Grocers Association (MGA) hosts a yearly bipartisan “bag-off.” Four elected officials from the state legislature compete to see who is the best at bagging groceries and are judged on speed and style The MGA’s “Bag Hunger” campaign seeks to partner grocers consumers and community agencies to end hunger Tom Hauser from KSTP 5 Eyewitness News emceed the event President of the Minnesota Grocers Association (MGA) Jamie Pfuhl hands Minnesota Senate minority leader Lisa Demuth first prize as workers wave picket signs and flyers Each bagger received $500 from MGA to be awarded to a charity in their constituency and a $2,000 check was also awarded to Second Harvest Heartland a hunger relief organization serving Minnesota and western Wisconsin MGA is responsible for one in 20 jobs in Minnesota Workers showed up to the event expecting to see MGA board chair which operates grocery stores in the Brainerd Lakes area the third and final day of the janitors’ ULP strike hundreds of workers and allies rallied at the Minneapolis–St which is consistently ranked as one of the best airports in the United States.  “Remember when they used to call us essential?” asks Brahim Kone Kone says the local lost five of its members during the Covid-19 pandemic has worked as a janitor cleaning MSP Airport for over a year “I’m working with people who have worked here for 20 or 30 years The wages and retirement that they are being offered is an insult to hardworking American families in inflationary times,” he says “I hope that they come up with something better so these people can keep this airport alive and keep it the best airport in America.” where he has worked for more than eight and a half years He stands with the striking janitors and union activist and former baggage handler Kip Hedges who was fired by Delta while fighting for a $15 minimum wage in 2014 Only the pilots and dispatchers at Delta have union representation but flight attendants and mechanics are also organizing a union drive “We know how much we’re losing out,” says Gores “A lot of people have a sense of rugged individualism and that beats you down and separates you from the power we have I have a lot of coworkers that are scared to speak up I’m sure there was fear in these people at one point but they understand the concept of strength in unity.” Alana Cross is a healthcare worker with SEIU Healthcare Pennsylvania who traveled to Minnesota to take part in the solidarity actions with workers this week in an act of civil disobedience after they refused to move from the street Dozens of airport police officers lined up to arrest the union activists including SEIU Local 26 political director Samantha Diaz Janitors return to work Thursday morning and expect to be back at the bargaining table on Friday Cristina Melchor is a leader with Unidos MN who has lived in Minnesota for over 20 years and suffered long-term damage to her hands at one of her jobs most of the jobs that I have access to have been through temporary agencies,” she says in Spanish through a translator “I hope that we are the last generation of frontline workers that have to harm our bodies to be able to bring sustenance to our families.” and Sierra Club joined SEIU Local 26 at Mercado Central in South Minneapolis to launch the “Block by Block” public initiative to bring clean energy and green union jobs to every neighborhood in the city the marketplace was one of the first buildings in the Lake Street business corridor to use solar energy but to commit to a 100% transition to renewable energy “We have the opportunity to impact an entire generation of workers but only if we do this right,” says Chelsie Glaubitz Gabiou president of the Minneapolis Regional Labor Federation which is working with Unidos MN and New Justice Project on sustainable pathways to long-term jobs the Minneapolis City Council approved $10 million in a climate legacy initiative to pursue climate goals like reducing energy costs creating green jobs and achieving carbon neutrality by 2050 “Minneapolis needs a Green New Deal,” says Council Member Katie Cashman chair of the Climate and Infrastructure Committee inviting everyone to its next meeting scheduled for March 14 “We need to hear your voices so we can ramp up this investment from 10 million to 100 million.” Around $1.4 million was also set aside for workforce development and another $4.7 million for weatherization Block by Block is an opportunity to ensure these funds will reach  communities that need it most Executive director of Unidos MN Emilia Gonzalez Avalos says that South Minneapolis is a sacrificial zone that suffers from historic disinvestment and pollution from nearby industrial facilities the East Phillips Neighborhood Institute and allies won almost a decade-long struggle against the city to prevent the demolition of the Roof Depot and build an urban farm with community services an iron metal processing plant whose air permit with the Minnesota Pollution Control Agency is up for renewal this year has also been under scrutiny for potentially violating the Clean Air Act Workers say that clean energy should not remain a luxury item reserved for the wealthy we would love a new modern electric stove and clean heat but we can’t afford new appliances or upgrades,” says Spencer Polk a renter with ISAIAH’s Young Adult Coalition we don’t have the power to make those changes in our building Our city leadership is going to be essential to make the clean energy transition something that benefits everyone: renters Centro de Trabajadores en La Lucha (CTUL) rally Members of Centro de Trabajadores en La Lucha (CTUL) a worker-led organization in the Twin Cities metro area have been demanding that developers like Solhem Properties which have histories of working with reportedly abusive contractors join the Building Dignity and Respect (BDR) program a worker-driven social responsibility program aiming to advance human rights and end exploitation within the construction industry non-union construction workers who are members of CTUL union members and renters rallied outside of the Solhem office in the North Loop neighborhood of Minneapolis said she saw the Solhem office’s window blinds go down while people began gathering for the rally two worker crews employed by subcontractors Fish Construction and PK Property Services reported wage theft while working on Solhem projects Workers received their wages weeks late after filing a lien and reaching out to the general contractor a group of women construction workers who have faced labor violations on Solhem projects knocked on Solhem’s door three times to ask Solhem to join BDR they read a letter addressed to CEO Curt Gunsbury out loud “While you don’t employ workers on your projects directly you set the expectations that dictate how workers are treated on your projects,” reads Socorro Cruz in Spanish through a translator With the support of her family and from CTUL Socorro and the other workers brought wage-theft complaints to the Minnesota Department of Labor and Industry CTUL sent a letter to the Edina City Council outlining concerns with new Solhem projects A letter to the city council from Gunsbury denies that wage theft has occurred on any Solhem projects and calls the allegations unfounded In documents shared with Workday Magazine and In These Times PK Property Services responded to a request for Cruz’s personnel file stating that “PK Property Services does not have any record of Socorro Cruz being employed with our company.” However paychecks showing that Cruz did not receive overtime wages list Giaveno Consultants and Paul Beckfeld the owner and founder of PK Property Services We hope that they take it and read it and recognize what’s going on,” says Cruz.  from United Renters for Justice/Inquilinxs Unidxs Por Justicia (IX) spoke at the rally about the need for affordable housing to not come at the expense of workers Rodriguez spoke at a forum hosted by IX and called for county-level social housing programs CTUL members put on some street theater showing how renters and workers can recognize shared interests against common enemies.  educators with Minneapolis Federation of Teachers (MFT) Local 59 Saint Paul Federation of Educators (SPFE) Local 28 Education Minnesota and SEIU Local 284 marched and rallied with allies at the Minnesota State Capitol deputy director at progressive organization TakeAction Minnesota SPFE worked with TakeAction to mobilize support for educators’ contract fights in making healthy “SPFE has a history of bargaining for the common good and this year we are feeling the power of the partnership between our labor unions and community allies,” she says SPFE announced they reached a tentative agreement with Saint Paul Public Schools after voting to authorize a strike set for March 11 the state legislature passed unemployment insurance for hourly school workers One of the next goals for these unions is winning an education support professionals (ESP) bill of rights which would increase wages for ESPs and provide them with health insurance and professional development Educators celebrated the funding appropriated through the state legislature last year they say working conditions continue to decline our bosses didn’t get that message,” says Catina Taylor “Instead of raising pay to compete with the private sector instead of standing up to the health insurance companies … We will keep pushing at the bargaining table we will keep supporting each other and our union siblings.” Melissa Grewe is a paraeducator at Mounds View who has been on union leave to attend the weeklong leadership school “This week has taught me that our fights are the same across jobs She says there was a moment when she became nervous at the bipartisan bag-off action with UFCW Local 663 on Tuesday “To my left were two strong women standing there beside me Friday marked an end to the week of action which saw over 5,000 workers and union members on strike including janitorial workers and nursing home workers with thousands of allies from unions and community groups in support 4,000 commercial janitors with SEIU 26 reached a tentative agreement at 4 a.m the agreement includes raising wages to $20 an hour From listening sessions with local government to civil disobedience to political theater to rallies workers built and displayed their collective power Several unions are still bargaining for their next contract Workday Magazine and In These Times will be updating this piece throughout the week to document this historic convergence Amie Stager is the Associate Editor for Workday Magazine Thousands of workers gathered on the steps of the Minnesota state capitol on May 1 Historical examples of workers resisting the oligarchical forces of fascism and authoritarianism and allies rallied together on the steps of Johnston Hall which contains the office of the University of Minnesota President Rebecca Cunningham’s to protest what they criticize as the University’s failure to forcefully object to ICE’s recent abduction of a graduate student and an onslaught of University policies limiting the freedom of speech across campus the crowd challenged the University’s policy that any gathering of more than 100 people must have a permit obtained two weeks in advance Get the latest on worker culture and power Metrics details now ranked within the class Acidithiobacillia are model bacteria for the study of chemolithotrophic energy conversion under extreme conditions Knowledge of the genomic and taxonomic diversity of Acidithiobacillia is still limited we present a systematic analysis of nearly 100 genomes from the class sampled from a wide range of habitats Some of these genomes are new and others have been reclassified on the basis of advanced genomic analysis thus defining 19 Acidithiobacillia lineages ranking at different taxonomic levels This work provides the most comprehensive classification and pangenomic analysis of this deep-branching class of Proteobacteria to date The phylogenomic framework obtained illuminates not only the evolutionary past of this lineage but also the molecular evolution of relevant aerobic respiratory proteins namely the cytochrome bo3 ubiquinol oxidases Considering the high taxonomic rank of the Acidithiobacillia little attention has been paid to their true diversity so far thereby leaving a considerable gap in our knowledge of these extremophiles studies performed so far have (i) overlooked the existence of different taxonomic ranks within the class Acidithiobacillia (ii) involved few representative strains of each species and/or (iii) undertaken biased sampling efforts recovering strains from a limited range of habitats or geographical origins Recognizing the limits of current knowledge of Acidithiobacillia we elected to test the hypothesis that the Acidithiobacillia class encompasses a greater number of genera and species than previously acknowledged and sequence new representatives of the class from diverse environments These included unconventional and little-reported niches such as geothermal acidic watersheds and near-neutral mineral environments we have sequenced the missing genomes of type strains of validated species of acidithiobacilli This work has aimed to reconstruct a robust genome-based phylogeny enabling the exploration of the ecological and metabolic origin of acidithiobacilli on the basis of their extant representatives Our work represents the state of the art for the knowledge of these extremely acidophilic bacteria and their physiology and sheds light into their evolutionary history DNA was sequenced using Illumina sequencing technology on the HiSeq 2000 platform producing 150 bp paired reads with a targeted insert size of 500 bp To ensure robust assemblies sequencing runs yielding >1,500,000 paired-end reads per sample were further processed where nodes are the variants and the edges are the presence/absence data or the statistical correlation data and bootstrap support was set at 1000 replicates We undertook a systematic study to analyze nearly 100 Acidithiobacillus genomes recovered from strains originating at geographically widespread locations and environmentally diverse habitats, half of which were added in this study (Table S1) This collection spans cultured representatives of all validated species of the taxon and candidate lineages and sublineages Genome size, protein-coding sequences, and G + C mol% differences within and between lineages (defined by 16S rRNA gene phylogenetic analysis and oligotyping) indicated that significant genetic variations occur within the Acidithiobacillia class (Table S8) A clear example of intraclade variation is A the strain genomes of which span at least six 16S rRNA gene sequence oligotypes and have about one-third difference in gene content Data collected support the existence of larger levels of genomic divergence than those expected for genomes pertaining to strains of similar taxonomic rank thus providing a clear indication of the taxonomic breath of the Acidithiobacillia class we assessed the validity of the existing taxonomic assignments within the class using state-of-the-art genome-based methodologies The acronyms presented on the right have been subsequently used throughout the manuscript This taxonomic diversity was further corroborated by the following phylogenomic analysis were analyzed using Bayesian inference (BI) Branches of interest are highlighted in the tree and labeled accordingly Posterior node support is shown as fractions Lineages are color coded according to their taxonomic affiliation as elsewhere in the manuscript Both clades appear to be early diverging (“early branching S-oxidizers”) with respect to the majority of those in the dual physiology subclade ferrianus which branches deepest within the Acidithiobacillus dual physiology subclade In partial agreement with previous reports based upon 16S rRNA gene trees, sulfur-oxidizing Acidithiobacillus spp. cluster in a different subclade from that containing all the iron/sulfur-oxidizing acidithiobacilli (Fig. 2B) The latter form a stable and monophyletic group which appears to have originated before the split between the ‘Igneacidithiobacillus’ and the ‘Fervidacidithiobacillus’ clades Such results support the genospecies uncovered in previous sections as true species requiring formal recognition and chemotaxonomic validation which ultimately determine the physiology and lifestyle of Acidithiobacillia taxa The integrated analysis of genomic distribution and phylogenetic patterns for the proteins involved in the above-mentioned traits of sulfur metabolism sustains the concept that the last common ancestor of the class was most probably a proficient sulfur-oxidizer the most likely source of these proteins was the ancestor of iron-oxidizing Acidiferrobacter thiooxydans of the Gammaproteobacteria class typical of anaerobic or microaerobic bacteria frequently associated with terminal oxidases with high affinity for oxygen This clade of the tree includes taxa that are known to be facultative anaerobes and may thus represent the relics of an ancestral state in the evolution of acidithiobacilli metabolism with subsequent differential loss of iron metabolism and anaerobic traits All members of the class posses several terminal oxidases of both high- and low-oxygen-affinity families none of which are conserved across all the class representatives alternative terminal oxidases showed differential patterns of occurrence pinpointing to different events of gene acquisition/loss A Phyletic pattern of terminal oxidases and relevant accessory proteins B Gene neighborhood of terminal oxidases in representative species of the class C Maximum likelihood phylogenetic tree of the heme A synthase CtaA genetically linked to either COX or bo3 oxidases D Extract of the sequence alignment of the COX2 subunit and its ortholog CyoA showing the copper-binding motif and its variation along acidithiobacilli taxa COX2 protein CEJ18213 is used as reference to identify key residues of the copper-binding motif This evidence strongly supports modular construction of chimeric oxidases in the Acidithiobacillia class The combination of this unique feature with the previously mentioned phylogenetic properties suggests that extant sulfur-oxidizing acidithiobacilli retain genomic and molecular remnants of the evolutionary transition of COX into CuA-lacking aa3 (ubiquinol) terminal oxidases As such remnants have not been found in other bacterial lineages it follows that Acidithiobacillia might be the originators of bo3 ubiquinol oxidases a hypothesis we will pursue in the immediate future the class Acidithiobacillia is among the basal lineages of Proteobacteria Conservation of the cysteins of the CXXXC CuA-binding motif and gene context-based association with heme A biosynthesis genes is symbolized in the right panel accordingly loss of heme A biosynthesis and complete degeneration of the CuA-binding motif brought about the transition of the A1-COX-aa3 into the A1 bo3 quinol oxidases found today in most Proteobacteria this study has significantly expanded the genomic countours of the Acidithiobacillia and highlighted important lacunae in our comprehension of the phylogenetic space occupied by the class The data and conclusions call for further exploration of unconventional environments including those that may be considered relics of the Earth’s past and for additional genomic studies of the Acidithiobacillia The phylogeny obtained thus far provides grounds to delineate the likely evolutionary scenarios of these extremophiles and further completes the emerging pamorama on the evolution of the phylum Proteobacteria In

Paulo Covarrubias and Hector Carrasco provided assistance with microbiological and molecular biology analyses at early stages of this study and Mario Vera shared strains used in this study We are grateful to Professor Aharon Oren (Hebrew University of Jerusalem Israel) for his help and advice on the projected names of novel bacterial genera and species The authors thank the authorities of the Provincial Thermal Baths Agency (EPROTEN) and the Directorate of Protected Natural Areas (ANP) of the province of Neuquén Argentina for allowing access and sampling in the Copahue-Caviahue Provincial Park and Ing Rubén Vargas (alias Caniche) for guidance during ascent to the Copahue volcano ANID–Millennium Science Initiative Program–Millennium Nucleus in the Biology of the Intestinal Microbiota Camila Rojas-Villalobos & Raquel Quatrini PROBIEN (CCT Patagonia Confluencia-CONICET Universidad Nacional Autónoma de México (UNAM) The authors declare no competing interests Publisher’s note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations Download citation DOI: https://doi.org/10.1038/s41396-021-00995-x Anyone you share the following link with will be able to read this content: a shareable link is not currently available for this article Among the most important athletics facilities in Italy the one in Giaveno was brought back to optimal conditions in 2019 Giaveno is a small municipality in the Piedmont region The Antonio Torta Stadium with adjoining grandstand is not quite as old The La Salle Sports Union athletics clubs currently train here The investment for the renovation of the outdated sports venue was intended to improve sporting facilities for Giaveno residents and young athletes in particular The facility simply lacked the necessary certification The old track at Antonio Torta Stadium dates back to 1992 and was exhibiting wear and tear the old surface was removed and the 400 m athletics track was equipped with a bright rainbow blue professional sports surface Rekortan M by Polytan It was installed in conjunction with Rekortan M in red for example as a boundary for the long jump start discus and javelin have been renovated and platforms for jumps and referees have been added Rekortan M is a coated surface whose granulate is interspersed with visible tips so it is absolutely spike-compatible and waterproof Athletes have been impressed by the benefits of the new track since June 2019: the surface stands for excellent acceleration and high tread elasticity It is also characterised by excellent damping and achieves the best values from a sports medicine perspective Privacy policy A community project steadily gaining ground and building bridges between Cuba and Italy Author: | informacion@granma.cu are proud for more than one reason: this was the first working class neighborhood built in Cuba named after one of the families of the country's most important intellectuals which has already surpassed its first century of existence there is also the noble history of its residents Those who first inhabited this neighborhood were manual workers and patriots who took up arms against the Spanish the documentary Mi Pogolotti querido (My dear Pogolotti) by Italian filmmaker Enrica Viola was presented to mark the 100th anniversary of this important area of the capital Several initiatives preceded the making of this film “El siglo de los Pogolotti en Cuba,” which gave rise to the book Dino Pogolotti which served as inspiration for two plays written in Italy and performed in Cuba with the support of the Ministry of Higher Education; the Group for the Comprehensive Development of Havana; the Marianao Municipal Assembly of People's Power; the Cuban Institute of Friendship with the Peoples; and the National Union of Writers and Artists of Cuba whose Cuban representative is Acela Caner Román Sinergia…is a project that can be very broad It’s not a project to focus on any one thing but rather if work needs to be done on the Casa de los Jóvenes (youth club) we focus on another need in the neighborhood Here in Marianao there is the Older Adults’ Association They have met with friends visiting from Italy and have performed plays We have received support from the Piedmont region of Italy There are many institutions who want to learn it’s uniting the forces we have and for each to make something unique that can be exceptional in terms of relations Sinergia plans to support the projects of the Comprehensive Transformation Workshop Depending on the needs of the Workshop and these projects Currently the Casa de los Jóvenes is being renovated This space was expanded to devote it to the youth who go there to socialize There are many artists in the Pogolotti neighborhood We participated for the first time in the last Havana Biennial thanks to the “Arte en Proceso” project We were joined by personalities such as Nelson Domínguez For us it is important that the community is involved and is reflected in this community work It is an effort for people to feel attached which is to produce an Italian and Cuban recipe book put together by members of the Marianao Older Adults’ Association and AUSER and the Italian Pensioners’ Union The (Italian) pensioners want to come to Cuba I have gained a lot from the community work in terms of the relationship I have with the people of Pogolotti very enthusiastic people with a strong sense of belonging as for many years they were very discriminated against Nobody has to knock on someone’s door asking for help These are the things I've been appreciating it is a very great pleasure to have Graziella here If you were to ask me what do we have to thank Dino Pogolotti for ‘For having given us Marcelo and Graziella' In Giaveno there is a Dino Pogolotti Society where an exhibition was recently presented that tells the story of this immigrant We hope that next year we can host an exhibition here in the Pogolotti neighborhood and that we can also show it elsewhere My interest is for our work to serve to better appreciate the Pogolotti family because they have extraordinary values which are well known here in Cuba I would like people to continue valuing the figure of Dino And may the neighborhood and people also be valued because beyond the architecture and position the most important aspect of Pogolotti is the people living here Serious work is undertaken with them and we are happy that the region the government and the authorities of Giaveno are proud It was almost a revelation for them to discover that there were such important and renowned personalities who came from there For us it has also been very good to get to know them There are things to be thankful for in life I am grateful that there are many good people in the world on the basis of what we can each humbly contribute with small actions  CONTEXT Italy in the roots of Cuban culture Dino Pogolotti (1873 - 1923) was born in Giaveno (Italy) Heemigrated to Cuba and raised a family here His son Marcelo and granddaughter Graziella became prominent Cuban intellectuals The first homes to be built in today's Pogolotti neighborhood were constructed on the family's Jesús María estate between 1910 and 1911 Graziella (1932) is one of the most prestigious Cuban intellectuals and has seen an extensive career as an essayist as well as having won important awards and recognitions for her intellectual work He was a founding member of the First European Social Painters Group He also wrote essays and was an art critic He is considered one of the icons of the Cuban artistic vanguard with topics dedicated to the analysis of the policy approved for this sector its relationship with the environment and the circular economy Interview granted by Miguel Mario Díaz-Canel Bermúdez First Secretary of the Central Committee of the Communist Party of Cuba and President of the Republic advocated on Tuesday that Biomodulin T should be part of primary health care in Cuban communities and that doctors should be prepared there to prescribe it
