A mercantilização em contramovimento : relações de reciprocidade e coesão social na agricultura sustentada pela comunidade em Minas Gerais

Eckert, Daniele January 2016 (has links)
O modelo convencional de organização da cadeia de produção e distribuição de alimentos é baseado na dependência cada vez maior do capital financeiro e industrial, no uso de agroquímicos, adubos, fertilizantes industriais e de outras técnicas provenientes da Revolução Verde, na livre circulação de mercadorias nos países e na inserção de intermediários na cadeia de distribuição. Esse modelo representa um movimento de mercantilização da agricultura e prejudica a autonomia dos indivíduos sobre a sua reprodução material e social, fazendo com que a sociedade enfrente um incremento de pobreza, insegurança alimentar, êxodo rural, danos à saúde e ao meio ambiente, assim como uma perda do senso de comunidade e de solidariedade. Além da compreensão do conceito e das formas de expressão do movimento de mercantilização, a lente teórica, que tem origem em Karl Polanyi, possibilita capturar o conceito da pluralidade e da coexistência dos princípios de regulação econômica e também do contramovimento como uma forma de resistência e de resgate da autonomia relativa dos indivíduos. É nesse contexto que a Agricultura Sustentada pela Comunidade (CSA) surge como uma possibilidade de contramovimento ao mercado convencional de alimentos ao adicionar uma qualidade ao ato de alimentar-se pela produção agroecológica e ao reconectar produção e consumo mediante o encurtamento da cadeia de distribuição. O problema que norteou a pesquisa desta dissertação foi compreender quais seriam as formas de contramovimento que se configuram na Agricultura Sustentada pela Comunidade diante da generalização do processo de mercantilização. Por isso, o objetivo geral consistiu em compreender e analisar, em uma experiência real de CSA situada na região sudeste do Brasil, os padrões de troca não mercantil em operação e os fatores que favorecem a autonomia relativa e elevam a coesão social de produtores e consumidores que participam da experiência observada. O método empregado foi a observação participante, utilizando as técnicas da etnografia. Em termos gerais, os resultados encontrados na pesquisa sinalizam que os indivíduos não são passivos diante dos efeitos da mercantilização e articulam-se em movimentos que buscam proteção e ganho de autonomia. Os resultados confirmam a hipótese inicial de que nas atividades de CSA coexistem, com a troca de mercado, outros princípios de regulação da economia, especificamente a reciprocidade, que aparece em diversos momentos, desde as motivações para o engajamento dos indivíduos até a forma em que a própria troca é realizada. Isso porque ao privilegiar nas suas trocas o ato em vez do objeto e do interesse privado, há menção a uma relação mais humana que permite o estabelecimento de amizade, solidariedade, tolerância, fidelidade e comprometimento mútuos, mas, principalmente, possibilita a ampliação da autonomia relativa dos indivíduos e o estabelecimento de um senso de comunidade, que se faz em torno do alimento. Na pesquisa, foram identificados três fatores específicos desta eficácia: a forma de produzir o alimento, oposto ao da agricultura tradicional, o encurtamento da cadeia e as atividades em conjunto mobilizadas pelo grupo de agricultores e consumidores. Desta forma, a Agricultura Sustentada pela Comunidade constitui um contramovimento à mercantilização na agricultura e aparece como uma alternativa eficaz na construção da autonomia daqueles que estão entrelaçados nessa rede de alimentos e na ampliação da coesão social. Os resultados e conclusões apresentados ao longo da dissertação ganham relevância na medida em que contribuem com novas informações e possibilidades de atuação na reversão do êxodo rural, na diminuição da pobreza, na redução de gastos públicos em saúde com uma alimentação mais saudável, assim como na promoção de iniciativas de preservação do meio ambiente. / The conventional model of organization of the production and distribution of food chain is based on the increasing dependence on the financial and industrial capital, the use of agrochemicals, fertilizers, industrial fertilizers and other techniques from the Green Revolution, the free circulation of goods in countries and the inclusion of intermediaries in the distribution chain. This model represents a movement of commodification of agriculture and undermines the autonomy of individuals concerning their material and social reproduction, leading society to a status of poverty, food insecurity, rural exodus, damage to health and environment, as well as to a loss of sense of community and solidarity. In addition to understanding the concept and the ways of expression of the commodification movement, the theoretical approach, based on Karl Polanyi, enables to capture the concept of plurality and coexistence of the principles of economic regulation and also the countermovement as a form of resistance and rescue of the individuals’ autonomy. In this context, the Community-Supported Agriculture (CSA) emerges as a possibility of countermovement to the conventional food market to add quality to the act of feeding by the agroecological production and to reconnect production and consumption by shortening the supply chain. The problem that guided the research of this dissertation was to understand what are the forms of countermovement that are present in the Community-Supported Agriculture before the generalization of the commodification process. Therefore, the overall objective was to understand and analyze, in a real experience of CSA located in southeast region of Brazil, the patterns of non-market exchange and the elements that favor the relative autonomy and increase social cohesion among producers and consumers participating in the observed experience. The method used was participant observation, using the techniques of ethnography. In general, the results found in the study show that individuals are not passive before the effects of commodification and they articulate in movements that seek protection and autonomy. The results confirm the initial hypothesis that, in the CSA, activities coexist with the exchange market, such as other principles of regulation of economy, especially reciprocity, which appears at various times, in motivation for engagement and in the way the exchange itself is performed. This happens because, when they prioritize their exchanges act instead of the object and the private interest, they develop a more human relationship that allows the establishment of friendship, solidarity, tolerance, mutual fidelity and commitment and also enable the expansion of autonomy of individuals and establish a sense of community, which is around the food. In this study, we have identified three specific elements that contribute to the effectiveness of the process: the way of producing food, as opposed to traditional agriculture, the shortening of chain and the activities in group promoted by the group of farmers and consumers. Thus, the Community-Supported Agriculture is a countermovement to the commodification in agriculture and an effective alternative in the construction of autonomy of those who are part of this net of food and in the expansion of social cohesion. The results and conclusions presented throughout the dissertation are relevant since they contribute with new information and possibilities of actions to slowdown rural exodus, alleviate poverty, reduce public spending on health with a healthier diet, as well as to promote the development of initiatives to preserve the environment.

Framtidens mathandel : En studie om direktförsäljning av mat från producent till konsument

Leife, Karl, Lerdell, André January 2017 (has links)
Under det senaste decenniet har det skett en förändring hos matkonsumenter i västvärlden. De aspekter som matkonsumenter tidigare fann relevanta har idag ersatts av nya, såsom att mat ska vara närproducerad, krav-märkt och hålla god kvalité. Effekten har blivit att det växt fram nya sätt att handla mat på som uppfyller dessa attribut. Ett koncept är Community Supported Agriculture (CSA), vilket i modern form innebär att privatpersoner och kommersiella aktörer kan köpa matvaror i form av direktförsäljning från lantbruk. Den här uppsatsen undersöker ett svenskt lantbruk vilket upprättat en direktförsäljning som en entreprenöriell sidoverksamhet till sitt traditionella lantbruk. Mer specifikt undersöks vilka värden som skapas för lantbrukets produkt, organisation, produktionsanläggningar och affärsrelationer, samt på vilka sätt resurserna hos några utvalda kunder till direktförsäljningen påverkas. Uppsatsen kommer fram till att nya värden skapas för lantbruket tack vare att det kan ta ut ett högre slaktpris genom direktförsäljning och att det skapar en närmare relation till sina kunder jämfört med i det traditionella lantbruket. Kunderna får tillgång till köttvaror med bättre kvalité tack vare direktförsäljningen, men behöver vara mer flexibla som organisation för att hantera lantbrukets produkter och dess leveransfrekvens.

Physical Activity and Changes in Abdominal Fat Over 18 Months: A Prospective Study of Middle-Aged Women

Davidson, Lance Eric 12 March 2003 (has links)
Objective: To investigate the extent to which changes in physical activity predict changes in abdominal fat in women over an 18-month period, while statistically controlling the effects of possible confounders, such as age, total body fat percent, and energy intake. Design: A prospective cohort design over 18 months. There was no intervention or treatment. Changes in objectively-measured physical activity were used to predict changes in abdominal fat over the study period. Subjects: 110 healthy, middle-aged women (mean: 41.3±3.3 yrs), primarily Caucasian, educated, and married. Measurements: An objective measure of physical activity (ACT) using CSA accelerometers, worn continuously for 7 consecutive days at baseline and again at follow-up. Total body fat and abdominal fat percent were assessed by dual energy x-ray absorptiometry (DEXA). Energy intake was estimated using 7-day, weighed food records for the days in which subjects wore accelerometers. Results: No significant change between baseline and follow-up means for abdominal fat, physical activity, or energy intake over the study period. Moreover, change in physical activity was not a significant predictor of change in abdominal fat, with or without statistical control of confounders. Change in energy intake was a predictor of abdominal fat (P=0.0688), and this association was strengthened after adjusting for age, baseline total body fat, and changes in physical activity. Conclusions: Apparently, when measured using accelerometers, changes in physical activity are not predictive of changes in abdominal fat over an 18-month period. However, changes in energy intake seem to predict changes in abdominal fat. Evidently, increases and decreases in abdominal fat are more a function of energy intake than physical activity in middle-aged women.

Spektrální analyzátor N1996A-503 a nejistoty měření / Spectrum Analyser N1996A-503 and Measurement Uncertainty

Trojan, Martin January 2011 (has links)
The main target of this master’s thesis is to introduce the reader with the spectrum analyzer, Agilent N1996A CSA. This work explains all the functions of this measuring instrument, control elements and presents some technical parameters. The next part of this thesis deals with the measurement of coaxial cables, so that is why a whole chapter is devoted to coaxial cables and conductors in general. The rest of this thesis deals with issues of measurement uncertainties. This part contains the general procedure for the evaluation of uncertainty, followed by a practical part. The practical part contains measurement of distance to fault and return loss. Measurements were made on 4 samples of coaxial cable. At the end of the practical parts the measured values including the uncertainties and results are summarized in the final paragraph.

Československé aerolinie v 70. a 80. letech z pohledu zaměstnanců podniku / Czechoslovak Airlines in the seventies and eighties from the viewpoint of the employees

Andraschko, Rudolf Vladimír January 2016 (has links)
This thesis deals with the career and private life of a specific group of employees of Czechoslovak airlines - cockpit crew, especially pilots - during the years 1970-1989 with a slight overlap into the 60's and 70's as the context of the work requires. This thesis is based on the method of oral history. Recordings with all the narrators were combined into integrated blocks of data, that shows how these people became pilots of Czechoslovak airlines but also how they managed to deal with everyday contact with the wide abroad, how their career progressed, how they were affected by changes in the history of Czechoslovakia and Czechoslovak airlines during the era of "Normalization". The author of this thesis tried to provide an insight into the history of pilot profession in the mentioned period based on creating a brief history of Czechoslovak airlines, archive materials concerning the trends in aviation and testimonies and interpretations of the narrators.

Kan företagsaktivism övertyga konsumenten? : En studie om hur företags sociopolitiska ställningstaganden påverkar konsumenternas attityd mot företagets varumärke / Can corporate activism convince the consumer?

Fidan, Mattias, Rosenblom, Matilda January 2021 (has links)
Metod: En kvalitativ metod med en induktiv ansats har tillämpats för denna studie. Empirin har samlats in genom fokusgruppsintervjuer, utförda vid fyra tillfällen med sammanlagt 15 deltagare. Fokusgruppssessionerna har spelats in, transkriberats, kodats, analyserats och presenterats utifrån induktiv metod, vilket även avser den tidigare forskningen. Resultat & Slutsats: Förväntningar på att företag skall uttrycka ställning för sociopolitiska frågor förekommer samtidigt som konsumenten är skeptisk till företagens underliggande motiv och trovärdighet i samband med ställningstaganden. Studien visar också att trots konsumentens skepticism har CSA en påverkan på attityden och att det beror på hur konsumentens personliga värderingar och åsikter förhåller sig till företagets ställningstagande.  Examensarbetets bidrag: Med anledning av att CSA är ett relativt nytt ämnesområde med stora begränsningar avseende tidigare forskning är förhoppningen att detta examensarbete skall bidra till ökad förståelse för fenomenet och samtidigt uppmana till vidare forskning.  Förslag till vidare forskning: Med utgångspunkt i begreppet “woke washing” föreslås vidare forskning kring hur företag kan nyttja CSA framgångsrikt. Förekommer gör även skäl att anamma uppsatsen syfte men med utgångspunkt i annan intressegrupp än konsumenten, exempelvis företagets leverantörer eller samarbetspartners. Vi föreslår även att vidare forskning fokuserar på CSA med inriktning på exempelvis så kallade lyxvarumärken då studien gett upphov till att misstänka konsumenten värderar CSA olika beroende på situation och produkt.

Block Periodization Programming: Efficacy in Subjects of Differing Strength Levels

Moquin, Paul 01 December 2020 (has links)
Physiological muscle adaptations due to resistance training are still not fully known. The rate and area of hypertrophy could drastically help or hinder athletic performance. The purpose of this study was to observe the changes in lean body mass (and related factors), relative allometrically scaled strength and absolute strength through an 11-week block periodized resistance training program. The subjects (n = 15) realized an increase in total body water (pre = 49.77Kg; post = 51.70Kg), lean body mass (pre = 67.98Kg; post = 70.63Kg), adjusted lean body mass (pre = 20.35Kg; post = 21.03Kg) and cross sectional area (pre = 32.73 cm2; post = 36.33cm2). Subjects (n= 15) were divided into either a strong (1 RM ≥ 1.75x body weight), moderate (1 RM = ≥ 1.25-1.74x body weight), or weak (1 RM < 1.25x body weight) group and data were analyzed in pre-post training. While all subjects showed gains in LBM and related factors, initial strength levels altered these adaptations. Subjects with a lower initial maximum strength level tended to make greater gains. However, due to the increase in total body water and relatively small increases in adjusted LBM, it appears, among this group, that little myofibrillar hypertrophy occurred during this short training period. These data suggest that greater accuracy for measures of alterations in LBM and related factors may require measures of total body water.

Community Supported Agriculture in Sweden and its transformative potential : A survey of farmers / Community Supported Agriculture i Sverige och dess transformativa potential : En enkätstudie av producenter

Källgren, Tom January 2021 (has links)
Modern agriculture has made great strides in terms of efficiency, yields, and profits, but has come to be characterised by a large environmental impact and resource use, global transports, poor working conditions, and a lack of contact between producers and consumers. In response to these concerns, many different initiatives commonly referred to as Alternative Food Networks (AFNs) have been established to solve some or all of these issues. One such AFN is Community Supported Agriculture (CSA) where customers of the CSA farm rather become members and pay upfront for a whole season of produce, sharing risks amongst all members and the farmer. The CSA concept, or andelsjordbruk as it is commonly known in Swedish, is still fairly unestablished in Sweden despite a few farms having been in operation since the start of the 2000s. This study aims to research some of the details regarding active CSAs in the country, as well as their potential to affect the whole national food system. The study was conducted through an online survey that garnered 17 respondents, as well as an accompanying literature review of previous works dealing with CSAs and AFNs internationally, with a focus on Sweden. In addition to this, the results of the survey were analysed with the help of Multi-Level Perspective and social innovations perspective as previously applied to AFNs.  Results of the study solidify many of the conclusions drawn by previous works while showcasing the diversity of Swedish CSAs. Some key conclusions from the respondents of this survey include that only a few farms were started more than five years ago and the model has only risen in popularity over time. The farms are run by a few people with varying degrees of external help from members of the CSA or others, and they often have other sources of income outside of the CSA side of the business. The respondents view the CSA model favourably compared to other forms of sales, mainly due to the social connection with consumers, but struggle to make it financially sustainable and thus most want to continue growing and gaining more members. The farmers are driven by several aspects of sustainability, personal fulfilment, and a drive to educate and inspire others as well as changing the food system for the better. The effects of the covid-19 pandemic were mainly felt in events and personal meetings on the farms, striking some of the key parts of the CSA model.  From both the multi-level perspective and social innovations perspective, the CSA model has a potential to affect the Swedish food system as a whole due to its replicability and high focus on inspiration and education, spreading ideas and knowledge and building social capital outside of the rules of the corporate food regime. The uncertainties regarding long-term financial viability speak against it, but these uncertainties are lessened by the farms who have been operating in the CSA model for many years and managed to thrive. / Den moderna jordbruksindustrin har gjort stora framsteg när det gäller effektivitet, skördestorlek och vinster, men har kommit att präglas av en stor miljöpåverkan och resursanvändning, globala transporter, dåliga arbetsförhållanden och brist på kontakt mellan producenter och konsumenter. Som svar på detta har många olika initiativ som vanligtvis på engelska kallas Alternative Food Networks (AFNs) etablerats för att bemöta några eller alla dessa problem. Ett sådant AFN är Community Supported Agriculture (CSA) där kunderna på CSA-gården snarare blir medlemmar och betalar i förskott för en hel säsong med råvaror vilket distribuerar risken bland alla medlemmar och lantbrukaren själv. CSA-konceptet, eller andelsjordbruk som det kallas i Sverige, är fortfarande ganska oetablerat i landet trots att några gårdar har varit i drift sedan början av 2000- talet. Denna studie syftar till att undersöka några detaljer kring aktiva CSA i landet, liksom deras potential att påverka det nationella livsmedelssystemet i stort. Studien genomfördes genom en webbaserad enkätundersökning med 17 respondenter, samt en medföljande litteraturstudie över tidigare arbeten som behandlar CSA och AFN internationellt men med fokus på Sverige. Utöver detta analyserades resultaten av undersökningen med hjälp av så kallat multi-level perspective och social innovations perspective såsom de tidigare tillämpats på AFN.  Resultaten av studien bekräftar många av slutsatserna från tidigare verk samtidigt som de visar mångfalden av svenska CSA-jordbruk. Några viktiga slutsatser från respondenterna i denna undersökning inkluderar att endast ett fåtal gårdar startades för mer än fem år sedan och att modellen har ökat i popularitet över tid, gårdarna drivs av några få personer med varierande mängd jordbrukshjälp från både medlemmar och icke- medlemmar, och de har ofta andra inkomstkällor utanför CSA-delen av verksamheten. Respondenterna har en positiv inställning till CSA-modellen jämfört med andra former av försäljning, främst på grund av den sociala kontakten med konsumenterna, men kämpar för att göra den ekonomiskt hållbar och de flesta vill därför fortsätta växa och få fler medlemmar. Lantbrukarna i denna studie drivs av flera aspekter av hållbarhet, personlig tillfredsställelse och en drivkraft för att utbilda och inspirera andra samt att förändra matsystemet till det bättre. Effekterna av covid-19-pandemin märktes främst vid evenemang och personliga möten på gårdarna, vilket slog hårt mot några av de viktigaste delarna av CSA-modellen.  Ur både multi-level perspective och social innovations perspective har CSA-modellen en potential att påverka det svenska livsmedelssystemet på grund av dess replikerbarhet och höga fokus på inspiration och utbildning, spridning av idéer och kunskap samt byggande av socialt kapital utanför reglerna för dagens livsmedelsregim. Osäkerheterna om långsiktig ekonomisk lönsamhet talar emot modellen, men dessa osäkerheter minskar tack vare de gårdar som har arbetat med CSA i många år och lyckats frodas.
