REFLEXIONES ANTROPOLÓGICAS EN TORNO A LOS SISTEMAS AGROALIMENTARIOS LOCALES: LA PROBLEMÁTICA DEL DESARROLLO ENDÓGENO EN LAS COSTAS AUSTRALES CHILENAS

Our purpose in the present work is to make a methodological contribution to enrich the SYAL concept from two points of view. Firstly, as a critical reconsideration of the theory of territorial development, and more specifically SYAL development, taking into account the fact that the local institutional framework is the result of the complex - even conflictive - interaction of economic rationales based on diverse cultural logics. Secondly, as an analysis of the strategies promoted by this type of development, identifying the endogenous components which strengthen and reinforce in local actors the ability to reflectively structure and re-structure system relationships at the territorial level. The empirical-ethnographic support for these reflections is drawn from two zones of Chile's southern coastline. The first, in the southern Aysen Region, illustrates the dilemmas and responses of local-traditional economies based on small-scale fishing in the face of the sustained growth of the captive salmon production mega-industry along a large part of the coastline. The second, in the neighbouring Los Lagos Region, reports on the strategies of traditional small-scale mussel-growers in the Reloncaví Estuary, in the context of the invasion of their economic space by multinational companies and the technification of their traditional systems.endogenous development, localised agro food system, small-scale fishing, reflection, hybridisation, subjectivity, Chile., Agribusiness, Agricultural and Food Policy, Community/Rural/Urban Development, Food Consumption/Nutrition/Food Safety, Labor and Human Capital,

Platform Workers in Europe Evidence from the COLLEEM Survey

The recent surge of digital labour platforms has led to new forms of work organisation and tasks distribution across the workforce. This has raised several questions about the functioning and the benefits deriving from the reorganisation of work that those platforms entail and the associated risks. The European Commission assessed online platforms in a May 2016 communication, focusing on both their innovation opportunities and regulatory challenges. In June 2016 the Commission also adopted its European Agenda for the Collaborative Economy, which clarified the concept and provided some guidance on the employment status of platform workers and the EU definition of worker. The European Pillar of Social Rights aims to address some of the policy challenges associated to new forms of employment, including platform work. As accompanying initiatives, the Commission presented in December 2017 a proposal for a new Directive on transparent and predictable working conditions, and in March 2018 a proposal for a Council Recommendation on access to social protection for workers and the self-employed. A crucial issue in designing the policy response to the emergence of digital labour platforms is the lack of reliable evidence. In 2017, the JRC conducted the COLLEEM pilot survey , an initial attempt to provide quantitative evidence on platform work, responding to calls by the European Council and the European Parliament. The survey provides a basis for an initial estimation of platform work in 14 Member States . How many platform workers are there in Europe? The COLLEEM survey contains a direct measure of service provision via platforms by the respondents in 14 EU Member States. It asks whether the respondent has ever gained income from different online sources, among which there are two corresponding to labour service platforms: "providing services via online platforms, where you and the client are matched digitally, payment is conducted digitally via the platform and the work is location-independent, web-based" and "providing services via online platforms, where you and the client are matched digitally, and the payment is conducted digitally via the platform, but work is performed on-location". Estimates indicate that on average 10% of the adult population has ever used online platforms for the provision of some type of labour services. However, less than 8% do this kind of work with some frequency, and less than 6% spend a significant amount of time on it (at least 10 hours per week) or earn a significant amount of income (at least 25% of the total). Main platform workers are defined as those who earn 50% or more of their income via platforms and/or work via platforms more than 20 hours a week. They account for about 2% of the adult population on average. There are significant differences across countries: the UK has the highest incidence of platform work. Other countries with high relative values are Germany, the Netherlands, Spain, Portugal and Italy. By contrast, Finland, Sweden, France, Hungary and Slovakia show very low values compared to the rest. Who are the platform workers? The typical European platform worker is a young male, educated to a degree level. The proportion of women decreases as the intensity of platform work increases. There is, however, substantial heterogeneity across countries. The fact that most platform workers are highly educated is not surprising given that to be able to provide services via platform one needs to be a savvy internet user, and internet use tends to be correlated with higher education. Despite conventional wisdom, a typical platform worker is likely to have a family and kids. Furthermore, regardless of age, platform workers tend to have fewer years of labour market experience than the average worker. Employment status of platform workers The employment status of platform workers is a controversial issue and one of the most relevant from a policy perspective. Estimates from the COLLEEM survey reveal that when asked about their current employment situation, 75.7 % of the platform workers claimed to be an employee (68.1%) or self-employed (7.6%). A first possibility is that platform workers also have a regular job as employees or self-employed (in a more traditional sense) and are therefore covered by standard employment legislation. A second possibility is that platform workers are not really sure of their employment status and may see themselves as employees, only because they provide a certain type of service with regularity through the same platform. This is surprising because in most cases the providers of labour services via platforms are formally independent contractors rather than employees, but it also reflects the uncertainty surrounding this issue in policy and even legal debates around Europe. In short, the labour market status of platform workers remains unclear, even to themselves. Interviewed platform workers declared themselves to be self-employed (as main or side job) in 54% of the cases, while a large minority (38 %) claim to be an employee. What types of services are provided and coordinated via labour platforms? Labour services provided by digital labour platforms can be broadly distinguished as services performed digitally (i.e. micro tasks, clerical and data entry, etc.) or services performed on-location (i.e. transport, delivery, housekeeping, etc.). On average half of the overall platform workers perform both digital and on-location services. According to the level of skills required by different services we can distinguish between: i) professional services (high skills); ii) non-professionals services (medium skills) and iii) on-location services (low skills). The majority of platform workers provide more than one type of services, and are active on two or more platforms, often combining high- and low skilled activities, suggesting that some platform workers may be reducing income risk (and possibly increasing variety in work). The most common labour service provided is 'online clerical and data entry'. However, the largest proportion of platform workers provides professional services. Gender also influences the type of services provided: 'software development' and 'transport' are the most male dominated services. By contrast, 'translation' and 'on-location services' are the mostly female dominated ones. The market for digital services is global and this may lead to some specialisation on services provided for some countries. The majority of the services do not show much variety across countries; however some country patterns could be identified. Slovakia and Croatia appear to specialise in services that require a low-medium level of education. Romania is amongst the top countries for the provision of non-professionals services The Netherlands mostly provides services that require high digital skills such as software and interactive. One third of platform workers have a mismatch between the lower-skilled tasks they perform and their high level of education/skills. What are the motivations and conditions of platform work? Flexibility and autonomy are frequently mentioned motivations for platform work, but these results should be interpreted cautiously: the lack of alternatives is also mentioned as an important motive for working on platforms. The conditions of platform work are more polarised than those of regular workers. Working conditions for platform workers appear to be flexible, but also intense. Platform work can be arduous and, for some workers, involving long hours. Key policy implications The implications of digital labour platforms for work and employment are ambivalent. On the one hand, they can lower the entry barriers to the labour market, facilitate work participation through better matching procedures and ease the working conditions of specific groups (i.e. workers with strong family responsibilities, people with disabilities or health conditions, youth, people not in education, employment or training – NEETs -, older workers, long-term unemployed, people with a migrant background). On the other hand, digital labour platforms typically rely on a workforce of independent contractors whose conditions of employment, representation and social protection are at best unclear, at worst clearly unfavourable. The status of platform workers is probably the most complex policy issue at stake. The actual nature of the employment relationship is nebulous in most cases. This is particularly problematic because employment status is key for access to social security, training entitlements and coverage by legislation on working conditions. Therefore the need for a clarification of the employment status of platform workers appears obvious. The findings presented in this report suggest an emerging phenomenon of increasing importance but still modest in size. If platform work remains significant but small in the future, a two-pronged policy response is likely to suffice, focusing on (i) fully grasping its job creation and innovation opportunities and (ii) adjusting existing labour market institutions and welfare systems to the new reality and mitigating its potentially negative consequences for working careers and working conditions. Examples of this are the proposal for a directive on transparent and predictable working conditions, and the proposal for a Council Recommendation on access to social protection for workers and the self-employed in the social fairness package adopted by the Commission on 13 March 2018 as well as the targeted legislative measures adopted by some countries. However, if platform work continues to grow in size and importance to become a more significant reality in our labour markets, or if some of the key features of platform work spread across other forms of employment as already seem to be happening in some cases, policy interventions may need to be of a more ambitious nature. Indeed, a scenario of general "platformisation" of labour markets and working conditions would require a profound rethinking of labour market institutions and welfare systems. Furthermore, a scenario in which there would be a significant increase in the provision of digitally performed platform work - people providing professional and non-professional labour services from their own places of origin - might lead to more opportunities for people to provide professional and non-professional labour services from their own places of origin – on-location services excluded - through a digital single market. A serious challenge in this scenario is the increased exposure of workers to global competition. From the regulatory point of view, the categories catering for the specificities of platform workers might be in need for a review. In a labour market with more unstable working careers, a wider use of schemes based on personal accounts for workers' entitlements might be required. From the social protection point of view, progress towards insurance models not based on employment status could be necessary.JRC.B.4-Human Capital and Employmen

Universality in Social Protection: An Inquiry about its Meaning and Measurement

This report aims to conceptualise universality in social protection and propose an actionable approach to measure it in a systematic and comprehensive way in the European Union. We propose to define the universality of a given Welfare State along three dimensions: the range of social needs addressed the degree to which the relevant population is covered, and the extent to which the needs are adequately covered in each case. We argue that these three dimensions can be used to measure the universality of European social systems. We discuss how this measurement could be implemented and present an illustrative operationalisation through a system of indicators for health, unemployment benefits, sickness benefits, old-age pensions, social assistance, housing, and education.JRC.B.7-Knowledge for Finance, Innovation and Growt

Zilpaterol hydrochloride improves growth performance and carcass traits without affecting wholesale cut yields of hair sheep finished in feedlot

Growth of the sheep meat industry throughout the world has been slow compared with meat industries of other domestic animals. Therefore, increasing productivity and efficiency of sheep meat production are key factors to enhance the competi- tiveness of this industry (Montossi et al. 2013). The use of β2- adrenergic agonists (β2-AA) as growth promoters has demon- strated to increase sheep meat production by improving protein deposition in muscle (Domínguez-Vara et al. 2013). The use of such technology in the lamb fattening systems could be a nutritional strategy to improve their competitiveness.Fourteen Dorper × Pelibuey ram lambs (initial body weight [BW] = 37.4 ± 1.0 kg and age = 4.5 mo) were housed in individual pens during a 30-d feeding period, and then slaughtered to determine the effects of zilpaterol hydrochloride (ZH) supplementation on productive performance, carcass characteristics and wholesale cut yields. Lambs were assigned under a randomized complete block design (initial BW as blocking factor) to one of two dietary treatments: basal diet without (control) or with 10 mg daily of ZH/lamb. Lambs fed ZH had greater (P ≤ .04) final BW, average daily gain and dry matter intake, but similar (P = .24) feed efficiency compared with control lambs. Hot and cold carcass weight, dressing percentage, longissimus muscle area and leg perimeter were greater (P ≤ .05) for ZH-fed lambs than for control lambs. With exception of blood percentage which decreased (P < .01) with ZH, wholesale cut yields and non-carcass components were unaffected (P ≥ .12) by ZH supplementation. In conclusion, ZH can be used to improve growth rate and dressing percentage, but not to increase wholesale cut yields in feedlot finishing ram lambs.This study was supported by PROMEP-SEP under the thematic network ‘Uso de Promotores de Crecimiento en Ovinos de Pelo (2014–2017

Racotumomab: an anti=idiotype vaccine related to N=glycolyl=containing=gangliosides: Preclinical and clinical data

Neu-glycolyl (NeuGc)-containing gangliosides are attractive targets for immunotherapy with anti-idiotype mAbs, because these glycolipids are not normal components of the cytoplasmic membrane in humans, but their expression has been demonstrated in several human malignant tumors. Racotumomab is an anti-idiotype mAb specific to P3 mAb, an antibody which reacts to NeuGc-containing gangliosides, sulfatides, and other antigens expressed in tumors. Preparations containing racotumomab were able to induce a strong anti-metastatic effect in tumor-bearing mice. Different Phase I clinical trials have been conducted in patients with advanced melanoma, breast cancer, and lung cancer. The results of these clinical trials demonstrated the low toxicity and the high immunogenicity of this vaccine. The induced antibodies recognized and directly killed tumor cells expressing NeuGcGM3. A Phase II/III multicenter, controlled, randomized, double blind clinical trial was conducted to evaluate the effect of aluminum hydroxide-precipitated racotumomab vaccine in overall survival in patients with advanced non-small cell lung cancer. The clinical results of this study showed a significant clinical benefit in the patients who were treated with the anti-idiotype vaccine.Fil: Vazquez, Ana M..

Preliminary report on the July 10–11, 2015 explosive eruption at Volcán de Colima: Pyroclastic density currents with exceptional runouts and volume

http://dx.doi.org/10.1016/j.jvolgeores.2015.11.022Reporte preliminar acerca de una de las últimas etapas eruptivas de Volcán de Colima, análisis realizado a partir de técnicas de percepción remotaOn July 10–11, 2015 an eruption occurred at Colima volcano produced 10.5 km long pyroclastic density currents (PDCs) along the Montegrande, and 6.5 km long along the San Antonio ravines. The summit dome was destroyed and a new crater excavated and breached to the south. This new breach connects to a narrow channel that descends along Colima's southern flank and was used by a subsequent lava flow. The Montegrande PDCs represent the longest and hottest flow of this type recorded during the past 30 years but are still smaller in comparison to the 15-km long PDCs produced during the 1913 Plinian eruption. Data obtained from field reconnaissance, lahar monitoring stations, and satellite imagery suggest that at least six PDCs occurred. The two largest PDCs (H/L 0.2) were able to surmount topographic barriers or bends. Based on field reconnaissance and digital elevation models extracted from SPOT satellite imageries we estimate a minimum volume for the valley-pond and distal fan deposits of 4.5 × 106 m3. After one week, the deposits were still hot with burning trees on the surface and millimeter-sized holes from which fumes were emanating. The juvenile components of the deposits consist of gray dense blocks and vesicular dark-gray blocks and bombs with bread-crust textures and cooling joints. The mineral association of these rocks consists of plagioclase + clinopyroxene + orthopyroxene + FeTi-oxides ± olivine and resorbed hornblende in a dark glassy matrix that corresponds to an andesitic composition.CONACY

A well-conserved Plasmodium falciparum var gene shows an unusual stage-specific transcript pattern

The var multicopy gene family encodes Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) variant antigens, which, through their ability to adhere to a variety of host receptors, are thought to be important virulence factors. The predominant expression of a single cytoadherent PfEMP1 type on an infected red blood cell, and the switching between different PfEMP1 types to evade host protective antibody responses, are processes thought to be controlled at the transcriptional level. Contradictory data have been published on the timing of var gene transcription. Reverse transcription-polymerase chain reaction (RT-PCR) data suggested that transcription of the predominant var gene occurs in the later (pigmented trophozoite) stages, whereas Northern blot data indicated such transcripts only in early (ring) stages. We investigated this discrepancy by Northern blot, with probes covering a diverse var gene repertoire. We confirm that almost all var transcript types were detected only in ring stages. However, one type, the well-conserved varCSA transcript, was present constitutively in different laboratory parasites and does not appear to undergo antigenic variation. Although varCSA has been shown to encode a chondroitin sulphate A (CSA)-binding PfEMP1, we find that the presence of full-length varCSA transcripts does not correlate with the CSA-binding phenotype

Micromorphology of spodic horizons of the restinga region of São Paulo State

Os solos de restinga são pouco estudados e conhecidos no Brasil. Neste trabalho, a micromorfologia de horizontes espódicos foi investigada em quatro locais do litoral do Estado de São Paulo (Bertioga, Ilha de Cananeia, Ilha do Cardoso e Ilha Comprida). A técnica possibilitou caracterizar as diferentes formas da matéria orgânica, e, juntamente com a descrição morfológica de oito perfis de solos representativos das restingas do Estado de São Paulo, objetivou-se discutir os mecanismos envolvidos na gênese dos horizontes espódicos desses ambientes. Entre os resultados alcançados, destaca-se: a presença de revestimentos orgânicos monomórficos na superfície dos constituintes grossos da maioria dos horizontes analisados, bem como o preenchimento quase completo da porosidade entre grãos de alguns horizontes cimentados e brandos, são evidências de que a clássica teoria da mobilização, transporte e precipitação de complexos organometálicos é válida para os solos estudados. No entanto, matéria orgânica polimórfica e, ou, resíduos vegetais em diferentes estádios de decomposição foram as principais pedofeições observadas em horizontes espódicos mal drenados e sotopostos a horizontes hísticos. Nesses, a decomposição pela mesofauna e microbiológica das raízes in situ é um importante mecanismo de acumulação de matéria orgânica em profundidade e formação dos horizontes espódicos. A atuação das raízes na formação desses horizontes, no entanto, vai além da sua decomposição: a fábrica e as feições da matéria orgânica de um horizonte cimentado, incluindo remanescentes radiculares, indicaram que as raízes podem atuar na imobilização da matéria orgânica por meio de seu mecanismo de absorção seletiva. Nesse processo, a solução do solo rica em carbono orgânico dissolvido é absorvida seletivamente pelas raízes, segregando parte do carbono complexado em sua superfície e no entorno destas, absorvendo água e nutrientes. A atuação continuada desse processo leva à precipitação da matéria orgânica iluviada e segregada por meio de sua desidratação, que é condicionada pela própria absorção radicular
