As cooperativas como instrumento de soerguimento das atividades em crise: vantagens, possibilidades e eventuais riscos sob o prisma da Economia Social

Esta dissertação apresenta estudo sobre o soerguimento de atividades em crise através da constituição de sociedades cooperativas por ex-empregados à luz dos princípios da Economia Social, dentro da área de concentração Pensamento Jurídico e Relações Sociais, na linha de pesquisa Empresa e Atividades Econômicas. Diante do crescente desemprego e precarização dos postos de trabalho, formas organizacionais autogestionárias, notadamente através de cooperativas, tem sido uma alternativa viável em muitos casos. A fim de demonstrar a viabilidade e utilidade de tais iniciativas, esta dissertação traçará uma evolução histórica das cooperativas e fará uma análise de sua estrutura legal (Lei n. 5.764/71) a fim de demonstrar que este tipo societário é a forma jurídica que mais se adéqua à proposta da Economia Social. A fim de atingir tal intento, a empregar-se-á o método indutivo, bem como revisão bibliográfica e análise de leis e projetos de lei na seara do Direito Societário e Direito do Trabalho, por se tratar de proposta interdisciplinar. Além disso, haverá pesquisa qualitativa e quantitativa de informações oriundas de bases de dados governamentais e de pesquisas do outros ramos do conhecimento. Ao enfrentar questões delicadas atinentes ao tema proposto buscar-se-á oferecer soluções a fim de contribuir para a maximização de tais experiências.

Community water access, availability and management in the Tonle Sap region, Cambodia.

During the rollout of CGIAR Research Program on Aquatic Agricultural Systems (AAS) in Tonle Sap in 2013, water management was highlighted as one of the key development challenges. With limited capacity to regulate water, the situation oscillates between too much water in the wet season and too little water in the dry season. Access to and availability of water were seen by local communities as major limitations for aquatic and agricultural production, impacting on functions that include the lake fishery, intensive (dry season) rice crops, recession rice, rainfed rice and floating rice by the lakeside. For both fish and rice production, water and water management are determined principally by the natural flooding of the Tonle Sap Lake. This study is based on a community survey on water access, availability and management and was conceived out of the AAS consultation process and was developed to help identify existing practices in water use and management, as well as best practices where lessons can be learned and promising activities scaled out to other communities. The community survey also aims to understand, identify and analyze constraints and opportunities related to water, and includes a gender perspective to better understand the role of women in water management and use.

Geographic and economic setting of Lake Victoria

Lake Victoria, besides being the second largest in the world after Lake Superior, is the largest tropical lake. Its waters are shared by Kenya (6% of the surface area), Uganda (43%), and Tanzania (51%). Before dramatic structural and functional changes manifested in the lake's ecosystem especially in the 1980s, fish life flourished in the lake's entire water column at all times of the year. Currently, the situation is much more different from what it was in the past. The exponential increase in the introduced Nile perch (Lates niloticus) and Nile tilapia (Oreochromis niloticus) stocks, siltation, wetland degradation and eutrophication have characterised the lake ecosystem. The two exotic species and the small native cyprinid (Rastrineobola argentea) form the basis of the commercial fishery that was once dominated by two native tilapiines (Oreochromis esculentus and Oreochromis variabilis) and five other large-bodied endemic fishes. Severe deoxygenation observed at shallow depths (Ochumba 1990; Hecky et al., 1994) indicates that a large volume of the lake is unable to sustain fish life. The Lake Victoria catchment is one of the most densely populated areas in East Africa, encompassing a population of about 30 million people. Widespread poverty resulting from high inflation rates, lack of opportunities and general unemployment have characterised the lakeside communities over much of the last two decades. The biophysical environment in which Lake Victoria exists makes the lake particularly susceptible to changes that occur as a result of human modification to the watershed or the lake itself, thus rendering benefits from the lake unsustainable.

How should governments support the emergence of new industries in leading economies?

Over the past 30 years, developed economies' approaches to supporting growth have focused on competitiveness, entrepreneurship and innovation to varying degrees. However, following the credit crisis and global recession in 2008 there has been demand for an updated narrative of growth based on the emergence of new industries. This paper provides a brief review of the available literature on how governments in leading economies can support new industries to emerge to the benefit of their national economy, discusses a number of issues for governments trying to support emerging industries, provides a framework of activities which governments considering this type of intervention should consider, and discusses the case of the regenerative medicine industry in the UK using the framework.

Microorganisms linked to Neoproterozoic microspar carbonate sedimentation in the Jilin-Liaoning area

Molar-tooth carbonate refers to a sort of rock that has ptygmatical folded structure comparable to the ivory. This kind of carbonate exists in a special time range (from Middle to Neoproterozoic). Its origin and the possibility to use it in stratigraphic correlation of the paleocontinent is the key task of the IGCP447, a project on Proterozoic molar tooth carbonates and the evolution of the earth (2001-2005). The importance lies in that the molar-tooth structure is the key to solving problems related to Precambrian biological and global geochemical events. The molar-tooth structure is associated with microorganisms. Development and recession of such carbonates have relations with the evolution process of early lives and abrupt changes in sea carbonate geochemistry. In recent years, based on researches on petrology, geochemistry and Sr isotope of molar-tooth carbonate in the Jilin-Liaoning and Xuzhou-Huaiyang area, the authors hold that it can be used as a marker for stratigraphic sequence and sedimentary facies analyses.

Impacts of anthropogenic activity on the recent evolution of the Huanghe (Yellow) River delta

Hydrological statistical data, remote sensing images, and bathymetric charts were used to study the recent evolution of the Huanghe (Yellow) River delta under human-induced interventions. It was clear that water and sediment discharge from the Huanghe River had dropped rapidly since 1970, particularly after 1986. The water and sediment discharges for the period of 1986-2000 were found to have been reduced to only 29.2% and 31.2% of those in the period of 1950-69. This was caused by human factors in the upper and middle reaches of the Huanghe River, including water diversion, damming and reservoir construction, and water and soil conservation. Based on the results from visual interpretation of processed Landsat (MSS or TMJETM+) images dated from 1976 to 2001 and two digital elevation models generated from bathymetric charts surveyed in 1976 and 1992, we found that human-induced reduction of water and sediment discharge led to coastline retrogradation, with the maximum mean recession rate of -0.51 km yr-1 over the period of 1976-98, and seabed erosion beyond the -20 m isobath between 1976 and 1992. Other impacts of human activities on the recent evolution of the Huanghe River delta, including tidal flats shrinking, artificial coastline increasing, land surface sinking and so on, were also analyzed. We found that: (i) the whole delta, including subaerial and subaqueous, has turned from a highly constructive period to a destructive phase; (ii) channelization and dredging were two of the main causes of delta destruction; (iii) land loss in the Huanghe River delta caused by submersion will be increased in the near future; (iv) the Huanghe River delta was becoming more fragile and susceptible to natural hazards.

Molecular phylogeny and biogeography of the Qinghai-Tibet Plateau endemic Nannoglottis (Asteraceae)

All taxa endemic to the Qinghai-Tibet Plateau are hypothesized to have originated in situ or from immediately adjacent areas because of the relatively recent formation of the plateau since the Pliocene, followed by the large-scaled biota extinction and recession caused by the Quaternary ice sheet. However, identification of specific progenitors remains difficult for some endemics, especially some endemic genera. Nannoglottis, with about eight species endemic to this region, is one such genus. Past taxonomic treatments have suggested its relationships with four different tribes of Asteraceae. We intend to identify the closest relatives of Nannoglottis by evaluating the level of monophyly, tribal delimitation, and systematic position of the genus by using molecular data from ndhF gene, trnL-F, and ITS region sequences. We find that all sampled species of Nannoglottis are a well-defined monophyly. This supports all recent taxonomic treatments of Nannoglottis, in which all sampled species were placed in one broadly re-circumscribed genus. Nannoglottis is most closely related to the Astereae, but stands as an isolated genus as the first diverging lineage of the tribe, without close relatives. A tentative relationship was suggested for Nannoglottis and the next lineage of the tribe was based on the ITS topology, the "basal group," which consists of seven genera from the Southern Hemisphere. Such a relationship is supported by some commonly shared plesiomorphic morphological characters. Despite the very early divergence of Nannoglottis in the Astereae, the tribe must be regarded to have its origin in Southern Hemisphere rather than in Asia, because based on all morphological, molecular, biogeographical, and fossil data, the Asteraceae and its major lineages (tribes) are supposed to have originated in the former area. Long-distance dispersal using Southeast Asia as a steppingstone from Southern Hemisphere to the Qinghai-Tibet Plateau is the most likely explanation for this unusual biogeographic link of Nannoglottis. The 23-32-million-year divergence time between Nannoglottis and the other Astereae estimated by DNA sequences predated the formation of the plateau. This estimation is further favored by the fossil record of the Asteraceae and the possible time of origin of the Astereae. Nannoglottis seems to have reached the Qinghai-Tibet area in the Oligocene-Eocene and then re-diversified with the uplift of the plateau. The molecular infragenetic phylogeny of the genus identifies two distinct clades, which reject the earlier infrageneric classification based on the arrangement of the involucral bracts and the length of the ligules, but agree well with the habits and ecological preferences of its current species. The "alpine shrub" vs. "coniferous forest" divergence within Nannoglottis was estimated at about 3.4 million years ago when the plateau began its first large-scale uplifting and the coniferous vegetation began to appear. Most of the current species at the "coniferous forest" clade of the genus are estimated to have originated from 1.02 to 1.94 million years ago, when the second and third uprisings of the plateau occurred, the climate oscillated and the habitats were strongly changed. The assumed evolution, speciation diversity, and radiation of Nannoglottis based on molecular phylogeny and divergence times agree well with the known geological and paleobotanical histories of the Qinghai-Tibet Plateau.

Wykluczenie społeczne wyzwaniem dla współczesnego świata

Społeczeństwo, w którym egzystuje współczesny człowiek, jest nie tyle trudne, ile bardzo złożone. Dlatego też wielu ludzi nie radzi sobie z różnymi problemami natury osobistej i społecznej. Wielu z nich doświadcza wykluczenia społecznego definiowanego jako efekt różnego rodzaju upośledzeń społecznych, wobec czego jednostka lub grupa nie może w pełni uczestniczyć w życiu gospodarczym, społecznym, ekonomicznym i politycznym społeczeństwa, do którego należy. Podmiotem wykluczenia społecznego jest przede wszystkim jednostka, która na drodze realizacji własnego humanitas została wykluczona w sposób przez siebie zawiniony lub doznała wykluczenia z powodu niewłaściwej polityki państwa. Do najważniejszych problemów lokujących się w obrębie wykluczenia autor zalicza: niepełnosprawność, bezrobocie, bezdomność, uzależnienia, samotność i ubóstwo. Scharakteryzowano przywołane powyżej obszary wykluczenia oraz podjęto próbę wskazania sposobów pomocy jednostkom, które stały się ofiarami wykluczenia. Podstawową instytucją pomagającą tym osobom jest pomoc społeczna, której pierwszym i podstawowym celem jest ulepszanie życia społecznego. Ważne miejsce zajmują w niej pracownicy socjalni, którzy jako jednostki wykształcone i kompetentne mogą wpływać na lepsze życie człowieka. Niestety, współcześnie nie zawsze w wystarczający sposób zaspokajane są podstawowe potrzeby zagubionych osób. Najsilniej dotykają one grupy i jednostki najsłabsze. Wskutek owych braków w polityce społecznej oraz w jej przedmiotowych zakresach: w polityce ludnościowej, rodzinnej, edukacyjnej, mieszkaniowej, polityce podziału dochodu, zabezpieczenia społecznego, zatrudnienia, następuje erozja najsłabszych ogniw systemu społecznego. Konieczne zatem wydaje się otwarcie polityki państwa na różne problemy społeczne, nie zawsze zawinione przez jednostkę, ale przez system, w którym się ona znalazła.

The effect of involuntary job loss on smoking intensity and relapse.

AIMS: To assess the impact of involuntary job loss due to plant closure or layoff on relapse to smoking and smoking intensity among older workers. DESIGN, PARTICIPANTS, SAMPLE: Data come from the Health and Retirement Study, a nationally representative survey of older Americans aged 51-61 in 1991 followed every 2 years beginning in 1992. The 3052 participants who were working at the initial wave and had any history of smoking comprise the main sample. METHODS: Primary outcomes are smoking relapse at wave 2 (1994) among baseline former smokers, and smoking quantity at wave 2 among baseline current smokers. As reported at the wave 2 follow-up, 6.8% of the sample experienced an involuntary job loss between waves 1 and 2. FINDINGS: Older workers have over two times greater odds of relapse subsequent to involuntary job loss than those who did not. Further, those who were current smokers prior to displacement that did not obtain new employment were found to be smoking more cigarettes, on average, post-job loss. CONCLUSIONS: The stress of job loss, along with other significant changes associated with leaving one's job, which would tend to increase cigarette consumption, must outweigh the financial hardship which would tend to reduce consumption. This highlights job loss as an important health risk factor for older smokers.

The creative masses of digital Britain

The present recession has prompted scholarly and journalistic questioning of the contributions of the cultural industries to the economy. The talent-rich metropolitan clusters of London and New York are well-placed to ride out a thoroughgoing shakeup of the media markets if they manage their infrastructure, space and resources strategically, as Richard Florida has recently argued. This seems to be the assumption behind the recent Digital Britain interim report, and Gordon Brown's remarks that a digital revolution "lies at the heart" of Britain's economic recovery and that broadband and the media industry can play a leading role in pulling the UK out of the recession. Focusing on the Digital Britain report and consultation documents, this presentation seeks to unpack some of the fundamental assumptions behind this link between digital infrastructure, creativity and profitability. In particular the implicit notion of an engaged audience of users, generating "content" as well as shaping new media platforms calls into question long-held theoretical constructions of the mass audience of consumers as spectators; instead, the audience emerges as a potential economic powerhouse, an underused resource for tomorrow's cultural industries.
