Sociální významy lokálních potravin a jejich spotřeby / Social meanings of local food and its consumption

Loučímová, Barbora January 2017 (has links)
Farmers markets, system of bio-boxes, community supported agriculture, yard sale and stores, is a summary of alternative forms of selling local food which can be found on our market. On the other side the newly established sections or shelves in supermarkets are starting to provide and include local food in their product range only after consumer pressure. Local food does not fall into one particular definition. Each of us under this designation can specified to what extent or distance of locality means to him. These foods have several advantages over conventional foods. Among the advantages is included growing in the Czech Republic, the absence of imports from distant countries, harvesting food at the time of ripening and more. Labeling, labeling method itself and the importance of brands is described in chapter political viewpoint.

Hierarchical Implementation of Aggregate Functions

Quevedo, Pablo 01 January 2017 (has links)
Most systems in HPC make use of hierarchical designs that allow multiple levels of parallelism to be exploited by programmers. The use of multiple multi-core/multi-processor computers to form a computer cluster supports both fine-grain and large-grain parallel computation. Aggregate function communications provide an easy to use and efficient set of mechanisms for communicating and coordinating between processing elements, but the model originally targeted only fine grain parallel hardware. This work shows that a hierarchical implementation of aggregate functions is a viable alternative to MPI (the standard Message Passing Interface library) for programming clusters that provide both fine grain and large grain execution. Performance of a prototype implementation is evaluated and compared to that of MPI.

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.

“Accumulation by Dispossession” by the Global Extractive Industry: The Case of Canada

Kinuthia, Wanyee 13 November 2013 (has links)
This thesis draws on David Harvey’s concept of “accumulation by dispossession” and an international political economy (IPE) approach centred on the institutional arrangements and power structures that privilege certain actors and values, in order to critique current capitalist practices of primitive accumulation by the global corporate extractive industry. The thesis examines how accumulation by dispossession by the global extractive industry is facilitated by the “free entry” or “free mining” principle. It does so by focusing on Canada as a leader in the global extractive industry and the spread of this country’s mining laws to other countries – in other words, the transnationalisation of norms in the global extractive industry – so as to maintain a consistent and familiar operating environment for Canadian extractive companies. The transnationalisation of norms is further promoted by key international institutions such as the World Bank, which is also the world’s largest development lender and also plays a key role in shaping the regulations that govern natural resource extraction. The thesis briefly investigates some Canadian examples of resource extraction projects, in order to demonstrate the weaknesses of Canadian mining laws, particularly the lack of protection of landowners’ rights under the free entry system and the subsequent need for “free, prior and informed consent” (FPIC). The thesis also considers some of the challenges to the adoption and implementation of the right to FPIC. These challenges include embedded institutional structures like the free entry mining system, international political economy (IPE) as shaped by international institutions and powerful corporations, as well as concerns regarding ‘local’ power structures or the legitimacy of representatives of communities affected by extractive projects. The thesis concludes that in order for Canada to be truly recognized as a leader in the global extractive industry, it must establish legal norms domestically to ensure that Canadian mining companies and residents can be held accountable when there is evidence of environmental and/or human rights violations associated with the activities of Canadian mining companies abroad. The thesis also concludes that Canada needs to address underlying structural issues such as the free entry mining system and implement FPIC, in order to curb “accumulation by dispossession” by the extractive industry, both domestically and abroad.
