Full Text Available BACKGROUND: Biogeographic patterns of species invasions hold important clues to solving the recalcitrant 'who', 'where', and 'why' questions of invasion biology, but the few existing studies make no attempt to distinguish alien floras (all non-native occurrences from invasive floras (rapidly spreading species of significant management concern, nor have invasion biologists asked whether particular habitats are consistently invaded by species from particular regions. METHODOLOGY/PRINCIPAL FINDINGS: Here I describe the native floristic provenances of the 2629 alien plant taxa of the Eastern Deciduous Forest of the Eastern U.S. (EUS, and contrast these to the subset of 449 taxa that EUS management agencies have labeled 'invasive'. Although EUS alien plants come from all global floristic regions, nearly half (45% have native ranges that include central and northern Europe or the Mediterranean (39%. In contrast, EUS invasive species are most likely to come from East Asia (29%, a pattern that is magnified when the invasive pool is restricted to species that are native to a single floristic region (25% from East Asia, compared to only 11% from northern/central Europe and 2% from the Mediterranean. Moreover, East Asian invaders are mostly woody (56%, compared to just 23% of the total alien flora and are significantly more likely to invade intact forests and riparian areas than European species, which dominate managed or disturbed ecosystems. CONCLUSIONS/SIGNIFICANCE: These patterns suggest that the often-invoked 'imperialist dogma' view of global invasions equating invasion events with the spread of European colonialism is at best a restricted framework for invasion in disturbed ecosystems. This view must be superseded by a biogeographic invasion theory that is explicitly habitat-specific and can explain why particular world biotas tend to dominate particular environments.

Full Text Available Los jardines son una importante fuente de bienes y servicios para los residentes de un hogar. Su función se traduce directamente en el tipo de plantas que en ellos se cultiva. Por otro lado, la terminología usada para denominar los distintos tipos de jardín en inglés (garden, homegarden, forest garden, etc. varía según su función y propósito. Los factores que explican la diferenciación y distribución de los jardines a escala global no habían sido previamente explorados hasta ahora. En este estudio se han analizado los inventarios florísticos de 44 conjuntos de jardines de to do el mundo para explorar sus similitudes taxonómicas y los factores que configuran la distribución de su flora. Para ello, se escogieron distintas variables biofísicas y socioeconómicas a una escala apropiada de trabajo. Como resultado, los factores biofísicos y climáticos (temperatura, precipitación, evapotranspiración potencial y distancia entre asentamientos se hallaron significativamente relacionados con la distribución de las especies; no obstante, todos estos factores resultaron ser menos importantes que el GDP (PIB per cápita, utilizado aquí como indicador de los ingresos del hogar, y que se obtuvo como el principal impulsor de la composición de los jardines. También el resto de factores sociales y culturales incluidos en el análisis, como son la similitud entre las lenguas de los distintos asentamientos o la densidad de población, se encontraron como variables significativas. Cabe señalar que el presente análisis omite cierto número de variables debido a la no disponibilidad de datos. Algunas de estas variables son el tamaño del jardín o el género de su dueño, las cuales han sido reconocidas previamente como agentes influyentes en la composición vegetal de los jardines. El estudio concluye que los géneros vegetales cultivados en los conjuntos de jardines son muy diferentes entre sí y que, por lo tanto, las distinciones entre

In order to detect floristic divergence of analysed stands we applied TWINSPAN classification and ordinary Correspondence Analysis. Both analyses have shown an almost identical result of floristic composition, where 114 studied samples were grouped into seven association groups at the third twinspan classification level. These seven groups, successively from the most humid to most dry, comprising two large groups of plant associations, completely corresponding to two alliances: Forest of Pedunculate Oak and Alder and Forest of Pedunculate Oak and Hornbeam. SIMPER procedure have shown tahat within the first 20.51% of cumulative contribution, the floristic divegence among the studied forest stands includes 13 taxa: Carpinus betulus., Fraxinus angustifolia, Quercus cerris, Amorpha fruticosa, Convallaria majalis, Crataegus oxyacantha, Quercus robur, Lysimachia nummularia, Tamus communis, Galium aparine, Rubus caesius, Ulmus carpinifolia and Ajuga reptans. ANOSIM analysis were used to determine the degree of floristic discontinuity. It was largest between forest of Pedunculate Oak, Hornbeam and Turkey Oak and forest of Pedunculate Oak and Ash (statistics R = 0.8824 (p<0.001)). The lowest floristic dissimilarity was between the forest of Pedunculate Oak, Hornbeam and Turkey Oak and forest of Pedunculate Oak, Hornbeam and Turkey Oak with Lindens, where R = 0.2009 (p<0.01). Posavina floodplain forests in Serbia generally show good agreement with analogous communities in neighbouring countries in the Balkan peninsula and Central Europe. (author)

The existence of social inequalities in health is well established. One strand of research focuses on inequalities in health within a single country. A separate and newer strand of research focuses on the relationship between inequality and average population health across countries. Despite the theorization of (presumably variable) social conditions as “fundamental causes” of disease and health, the cross-national literature has focused on average, aggregate population health as the central outcome. Controversies currently surround macro-structural determinants of overall population health such as income inequality. We advance and redirect these debates by conceptualizing inequalities in health as cross-national variables that are sensitive to social conditions. Using data from 48 World Values Survey countries, representing 74% of the world’s population, we examine cross-national variation in inequalities in health. The results reveal substantial variation in health inequalities according to income, education, sex, and migrant status. While higher socioeconomic position is associated with better self-rated health around the globe, the size of the association varies across institutional context, and across dimensions of stratification. There is some evidence that education and income are more strongly associated with self-rated health than sex or migrant status. PMID:29104292

Full Text Available The prevalence and increase, specially in recent years, of diverse problems (social, economic environmental particularly in Latin America have led various sectors to question globalization as a convenient model for the development of these countries. In this article we present and analyse, in general terms, some notions, characteristics and implications of globalization, from two antagonistic versions: The first of them refers to the notion of globalization from the point of view of its creators and adepts, while the second one is based on the version ellaborated by its oponents. In this regard, we present some similarities between the first version with the dominant paradigm in science and between the second one with emergent paradigms. Thus, in the first version globalization is understood as the unique, universal, undeniable and irreversible reality, whereas in the second one various constructions regarding globalization, which signify this phenomenon as culturally and historically constructed and hence dynamic, are formulated. This second version serves us as base for analysing the impact of globalization on economically deprived communities in our continent and simultaneously for illustrating the potentialities of these communities, empowered through the contributions of community social psychology, for resisting unfavourable effects of globalization upon them

A wide range of studies show global environmental change will profoundly affect the structure, function, and dynamics of terrestrial ecosystems. The research synthesized here underscores that biocrust communities are also likely to respond significantly to global change drivers, with a large potential for modification to their abundance, composition, and function. We examine how elevated atmospheric CO2 concentrations, climate change (increased temperature and altered precipitation), and nitrogen deposition affect biocrusts and the ecosystems they inhabit. We integrate experimental and observational data, as well as physiological, community ecology, and biogeochemical perspectives. Taken together, these data highlight the potential for biocrust organisms to respond dramatically to environmental change and show how changes to biocrust community composition translate into effects on ecosystem function (e.g., carbon and nutrient cycling, soil stability, energy balance). Due to the importance of biocrusts in regulating dryland ecosystem processes and the potential for large modifications to biocrust communities, an improved understanding and predictive capacity regarding biocrust responses to environmental change are of scientific and societal relevance.

Full Text Available Citizenship is considered as a legal relationship in the basis of which is a social fact, a feeling and solidarity interest, combined with reciprocity of rights and obligations.1 Citizenship is a legal expression for the fact that the person who posses that, attributed to him by the law or by an act, is more closely associated with the population of the state of his citizenship than the population of any other state. At the moment obtaining the citizenship, it is also granted the possibility to exercise the right in international level, by the states, for the diplomatic protection of its citizens in cases when they are punished. This justifies and legitimizes the requirements of states for granting citizenship in terms of performance and behavior2 , imposing restrictions such as military service; payment of tax liabilities or exercise of jurisdiction. Citizenship is considered a fundamental category for the understanding of liberal democracy. It is considered a strategic element to understand the organization and functioning of democratic institutions (Zolo, 1994, IX. Citizenship is considered an important element as, through the sociological legal approach, it helps us to link individual rights to the political environment. It also affects the analysis of the relationship between the state level of the rights protection and the international one on which it depends, in an increasingly global society, the possibility of the effective enjoyment of the rights and freedoms. If we were to ask a simple question of who was considered a citizen, we would immediately create a circle of people who have relations with the state in terms of family background or territorial affiliation. This category of persons, considered as citizens, is easily distinguished by foreigners because they are subject to the legislation of another country, and consequently posses the rights and also must fulfil the obligations established in their own country. Thus, citizenship

First palynological data, supplemented by detrital zircon U-Pb ages, from the Fenestella Shale Formation near the Gund Village in the Banihal area of Jammu and Kashmir State, India, provide new insights into the floristic evolution of Gondwana during the Late Palaeozoic, especially in India, from where the Carboniferous-Permian macro- and microfloral records are impoverished. We also present a first approach to the palynological correlation of the Carboniferous-Permian palynoassemblages described from the various Gondwana countries. The palynomorphs from the Fenestella Shale Formation are fairly well preserved and diversified and include 11 genera and 18 species. While the trilete spores and striate bisaccate pollen grains are scarce, monosaccate pollen taxa mainly - Parasaccites, Plicatipollenites and Potonieisporites are dominant. The assemblage is most similar to the Parasaccites korbaensis palynozone of the Lower Gondwana basins of the Indian peninsula and the Stage 2 palynozone of the late Carboniferous of east Australia. Besides, it is comparable with the known Carboniferous assemblages of Pakistan, Yemen and South America; Carboniferous-early Permian assemblages of South Africa and Permian assemblages of Antarctica. The sediment source of the siliciclastic shelf and delta deposits intercalated in the Fenestella Shale Formation is a hinterland in which Precambrian rocks dominantly were exposed and the Th-U ratios of detrital zircons suggest, that most rocks exposed on the erosion level in the hinterland had a felsic composition. The youngest U-Pb zircon age of the investigated fossiliferous strata is 329 ± 16 Ma (late Visean to early Serpukhovian), providing a maximum age of deposition of the studied succession. Based on the affinities of the palynofloral assemblage and earlier palaeontological records, a warm, temperate and arid climate has been inferred for the Fenestella Shale Formation.

Full Text Available Globalization represents a controversial phenomenon both because of its complexity and because of the various implications it has on the global economy. Globalization will act simultaneously on many levels, its effects being correlated with the diversity of the angles from which this phenomenon can be approached from – economic, social, politic, cultural, philosophic etc. The article represents an incursion into the issue regarding the implications and effects of globalization grouped in several areas of analysis such as the disappearance of borders, the effects on culture, the effects on the education, the impact on labour market impact and the phenomenon of immigration, the effects of globalization in the context of the food crisis underdevelopment and poverty. To complete the analysis that points out enough elements considered to be negative, at the end of the article, there are also approached the development opportunities that globalization can offer in terms of boosting the economic exchanges, the exchange of genuine cultural values and ensuring a transfer of information at a global scale, so necessary for the scientific and technological progress. The conclusions of the article weighs the many aspects highlighted, both negative and positive, and suggests a series of useful research directions in order to fathom the complex features of this concept so controversial – globalization.
In recent years, multinational corporations were increasingly engaged in the development of standardized global workplace models. For their implementation and feasibility, it is decisive as how these standards fit the diverse regional workplace cultures. This topic was pursued in the course of a research project, comparing established workplaces in Germany, USA and Japan against global workplace standards of multinational corporations. The analysis confirmed the expected differences among local workplaces and on the other hand a predominant mainstream among global corporate workplace standards. Conspicuous however, are the fundamental differences between local models and corporate standards. For the implementation of global standards in local context, this implies multiple challenges on cultural, organizational and spatial level. The analysis findings provide information for assessing current projects and pinpointing optimization measures. The analysis framework further provides a tool to uncover and assess n...

High-quality research is essential for the generation of scientific nursing knowledge and the achievement of the Millennium Development Goals. However, the incorporation of Western bioethical principles in the study design may not be suitable, sufficient or relevant to participants in low-income countries and may indeed be harmful and disrespectful. Before engaging in global health studies, nurses must consider carefully the cultural and social context and values of the proposed setting in order to situate the research within the appropriate ethical framework. The purpose of this paper was to examine the ethical principles and considerations that guide health research conducted in international settings using the example of a qualitative study of Ugandan nurses and nurse-midwives by a Canadian researcher. The application of Western bioethical principles with their emphasis on autonomy fails to acknowledge the importance of relevant contextual aspects in the conduct of global research. Because ethics is concerned with how people interact and live together, it is essential that studies conducted across borders be respectful of, and congruent with, the values and needs of the community in which it occurs. The use of a communitarian ethical framework will allow nurse scientists to contribute to the elimination of inequities between those who enjoy prosperity and good health, and those who do not.

First, in 2000, the United Nations Millennium Goals explicitly and implicitly addressed health promotion and prevention at the global and regional levels. Second, the concern for sustainable development at the Rio Conference in 1992 was confirmed at the World Summit in Johannesburg in 2002. During the same period, in many regions including Europe, the redefinition of the roles and responsibilities of national, regional and local governments, reductions in budgets of public administrations, the privatization of community and health services, the instability of world trade, the financial system and employment, migration flows, relatively high levels of unemployment (especially among youth and young adults) have occurred in many countries in tandem with negative impacts on specific policies and programmes that are meant to promote health. Since 1990, the European Commission has been explicitly concerned about the promotion of health, environment and social policies by defining strategic agendas for the urban environment, sustainable development and governance. However, empirical studies during the 1990s show that urban areas have relatively high levels of tuberculosis, respiratory and cardiovascular diseases, cancer, adult obesity, malnutrition, tobacco smoking, poor mental health, alcohol consumption and drug abuse, sexually transmitted diseases (including AIDS), crime, homicide, violence and accidental injury and death. In addition, there is evidence that urban populations in many industrialized countries are confronted with acute new health problems stemming from exposure to persistent organic pollutants, toxic substances in building structures, radioactive waste and increasing rates of food poisoning. These threats to public health indicate an urgent need for new strategic policies and

Full Text Available A comparative analysis of the rate of growth in exports of goods and GDP is carried out, and goods exports to GDP ratio in the context of the developed countries, developing countries, and countries with the transition economy is calculated. This allows to make a conclusion about a decrease in importance of exports as a key engine of the world economic growth during the past years. The legal basis of the WTO’s activities in terms of state support for exports is described. The main reasons for the emergence of a conflict of interests between countries with different levels of economic development concerning the use of individual protectionist barriers are revealed. Potential long-term consequences of the growth of export orientation under conditions of openness of national economies are identified. The measures and tools of the country’s export promotion in foreign markets are studied. It is grounded that under conditions of destabilization of global trade regulators, effective export promotion is a mechanism for increasing the competitiveness of the national economy of Ukraine. Prospects for further research in this area are the determination of instruments to stimulate exports, which have the greatest impact on the export orientation of certain economic activities.

Essential sources of information were professional publications , statistic data of state Statistics Department, Bank of Lithuania, Euro stat. Scientific aim: Main aim of this article is to analyze the transformation of the Lithuania financial system and fined out the country’s economic growth and the financial system correlation, the main factors having a both positive and negative impact on economic growth. Findings: Findings of this article are new information in this area, which can be useful for another research. The correlation between the banks ‚ loans and GDP. However, this does not apply at the time of the economy fall. Conclusions: Economic growth in the financial sector and economic development is best visible analyzing in the correlation between the banks ‚ loans and GDP. However, this does not apply at the time of the economy fall. Banks ‚ relative indicators better reflects the weight of the financial sector and the impact on the national economy. We can see that 2011 banks relative indicators dropped to 2006 level. This shows how much the financial sector’s contribution decreased to economic development. Banks’ loans demand fall down. Lithuania has taken strict fiscal discipline and austerity measures. This have produced results quite quickly, in 2010 GDP grew by 3.4 percent, and in 2011 even 11.5 percent. Lithuania’s economy is recovering, but the financial sector and in particular banks still not recovering. The economic crisis has intervened in the banking system and has been surviving

What role sustenance of biodiversity and contrasting ecosystem services should play in achieving a sustainable future varies along philosophical, cultural, institutional, societal, and governmental divisions. Contrasting biophysical constraints and perspectives on human well-being arise both within and across countries that span the tropics and temperate zone. Direct sustenance of livelihoods from ecosystem services in East Africa contrasts with the complex and diverse relationships with the land in Mexico and the highly monetary-based economy of the United States. Lack of understanding of the contrasting contexts in which decision-making about trade-offs occurs creates impediments to collective global efforts to sustain the Earth's life support systems. While theoretical notions of the goals of sustainability science seek a unified path forward, realities on the ground present challenges. This Special Feature seeks to provide both an analytical framework and a series of case studies to illuminate impediments posed to sustainability by contrasting biophysical constraints and human perspectives on what should be sustained. The contributors aim to clarify the trade-offs posed to human welfare in sustaining biodiversity and ecosystem services and the challenges in managing for a sustainable future in which human well-being is not compromised as compared to today. Our goal is to provide novel insights on how sustainability can be achieved internationally through exploration of constraints, trade-offs, and human values examined at multiple scales, and across geographic regions from a range of cultural perspectives.

Habitat loss and climate change are primary drivers of global biodiversity loss. Species will need to track changing environmental conditions through fragmented and transformed landscapes such as KwaZulu-Natal, South Africa. Landscape connectivity is an important tool for maintaining resilience to global change. We develop a coarse-grained connectivity map between protected areas to aid decision-making for implementing corridors to maintain floristic diversity in the face of global change. The spatial location of corridors was prioritised using a biological underpinning of floristic composition that incorporated high beta diversity regions, important plant areas, climate refugia, and aligned to major climatic gradients driving floristic pattern. We used Linkage Mapper to develop the connectivity network. The resistance layer was based on land-cover categories with natural areas discounted according to their contribution towards meeting the biological objectives. Three corridor maps were developed; a conservative option for meeting minimum corridor requirements, an optimal option for meeting a target amount of 50% of the landscape and an option including linkages in highly transformed areas. The importance of various protected areas and critical linkages in maintaining landscape connectivity are discussed, disconnected protected areas and pinch points identified where the loss of small areas could compromise landscape connectivity. This framework is suggested as a way to conserve floristic diversity into the future and is recommended as an approach for other global connectivity initiatives. A lack of implementation of corridors will lead to further habitat loss and fragmentation, resulting in further risk to plant diversity.

Energy sources available in the world include: coal, oil, gas, biomass, nuclear, hydroelectric, wind, solar, refuse-based, and hydrogen. In addition, fusion had been originally proposed as the long-term source. Every form of energy generation has both advantages and disadvantages. Burning fuel for energy requirements represent about 88% from the total emission of NO x and CO 2 , and about 90% from SO 2 respectively, and about 72% from suspension powder evacuated into the atmosphere. Global warming represents a real threat and is the most visible sign of the climatic changes which take place all over the world. To reduce the emission of greenhouse gases: carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF 6 ), the 'Kyoto Protocol to the United Nations framework convention on climate change' has been adopted in 1997. According to this protocol European countries must reduce their overall emissions of greenhouse gases by at least 5% below 1990 levels in the commitment period 2008 -- 2012. In this context, because the natural resources for power generation based on the fossil fuels are decreasing and their prices are rising, nuclear power has become a real alternative for classical energy sources. It is indicated by: - Fuel is inexpensive because uranium represents a very small part of nuclear power cost and uranium sediment is found on a large scale all over the world; - No greenhouse emission or acid rain effects occur during a normal operation. Nuclear power is also named 'clean energy'; - Wastes are more compact than those of any source of energy and are stored in underground and secured deposits; - Nuclear energy has a number of advantages which warrant its use as one of the many methods of fulfilling the energy-demand of the world. Even with conservation efforts, energy demand increased and will continue to increase. Using each and every one of these forms of energy

Globalization is a phenomenon traceable historically from the beginning of time as clans and tribes migrated and learnt from each other. The article in this issue of INR by Grootjans and Newman 'Globalization and nursing: a concept analysis' (pp. 78-85) makes the case for nurses to be educated about globalization as it applies to modern health care. The concept is complex and requires insight not only into health care itself but also fields such as human migration, economics, the significance of English as a universal language and the use and availability of information technology. Writings on the impact of global technology and social capital are also important. In addressing globalization, nurses need to access research and writings well beyond the standard healthcare oeuvre. © 2013 The Author.

Icons are small signs with fixed meanings. Icons are usually context specific. For example in the context of a hotel, the client can often find icons in hotel room books and safety guides. Scandic Hotel chain, for example, currently provides the manual for its safety system in 14 languages. There are at least two major shortcomings of this system: (1) in emergency or panic situations, it is very difficult to find your own language from the leaflet, and (2) there are no Asian ...

In real life, the processing of an incoming event is continuously influenced by prior information at multiple timescales. The present study investigated how harmonic contexts at both local and global levels influence the processing of an incoming chord in an event-related potentials experiment. Chord sequences containing two phrases were presented to musically trained listeners, with the last critical chord either harmonically related or less related to its preceding context at local and/or global levels. ERPs data showed an ERAN-like effect for local context in early time window and a N5-like component for later interaction between the local context and global context. These results suggest that both the local and global contexts influence the processing of an incoming music event, and the local effect happens earlier than the global. Moreover, the interaction between the local context and global context in N5 may suggest that music syntactic integration at local level takes place prior to the integration at global level.

To assess critically the scope for public health nutrition taxation within the framework of the global tax reform agenda. Review of the tax policy literature for global policy priorities relevant to public health nutrition taxation; critical analysis of proposals for public health nutrition taxation judged against the global agenda for tax reform. The global tax reform agenda shapes decisions of tax policy makers in all countries. By understanding this agenda, public health nutritionists can make feasible taxation proposals and thus improve the development, uptake and implementation of recommendations for nutrition-related taxation. The priorities of the global tax reform agenda relevant to public health nutrition taxation are streamlining of taxes, adoption of value-added tax (VAT), minimisation of excise taxes (except to correct for externalities) and removal of import taxes in line with trade liberalisation policies. Proposals consistent with the global tax reform agenda have included excise taxes, extension of VAT to currently exempted (unhealthy) foods and tariff reductions for healthy foods. Proposals for public health nutrition taxation should (i) use existing types and rates of taxes where possible, (ii) use excise taxes that specifically address externalities, (iii) avoid differential VAT on foods and (iv) use import taxes in ways that comply with trade liberalisation priorities.

Full Text Available Globalization shows that the national State is losing the monopoly in the production of law, and this generates changes concerning the environment of application of the state legal arrangements and the role of the territory as the limit thereof. The object of this work is to offer a panorama about of the law globalization impacts on the State, the constitutional theory and the territory. The study is performed by means of the documentary review technique by using the consultation of diverse sources. Our conclusion is that the Westphalian model of State-nation has been weakened; however, globalization needs the State to be able to operate. Law has been deterritorialized and the territory continues to be a fundamental element for the contemporary State.
Full Text Available The article provides efficiency assessment regarding existing mechanisms of the U.S. national interests’ implementation at the global level in terms of international competition aggravation and formation of the new global economic competition centers. Based on comparative analysis of the leverage for U.S. leadership in global competition it has been proven that currently the highest efficiency is demonstrated by the integration strategies of the USA in Latin America focused on maximizing implementation of the economic interests of U.S. transnational corporations in the region. It has been proven that the observed profound asymmetries regarding socio-economic development of the North and Latin America countries objectively requires implementation of the effective institutional mechanisms for leveling the negative effects generated by the trade and investment liberalization processes.
The paper examines the extent to which nuclear power could help ameliorate the greenhouse problem. Topics discussed include: (1) How serious is the environmental threat posed by the greenhouse effect? (2) How large a part do fossil fuels play in producing greenhouse gases? (3) Is it possible to prevent or abate the anticipated global warming? (4) Can nuclear power play a significant role? (5) What overall approached might best reduce greenhouse emissions? Global cooperativeness in addressing the problem will be essential. 14 refs., 5 tabs

This paper argues that energy efficiency and conservation is a noncontroversial, critical, and equitable option for rich and poor alike. Although there is growing scientific and political consensus on its significance as an important option at global and national level, the political momentum for taking action is not commensurate with the potential in the sector or the urgency with which measures need to be taken to deal with climate change. The current global energy (efficiency) governance framework is diffuse. This paper submits that there are four substantive reasons why global governance should play a complementary role in promoting energy efficiency worldwide. Furthermore, given that market mechanisms are unable to rapidly mobilize energy efficiency projects and that there are no clear vested interests in this field which involves a large number of actors, there is need for a dedicated agency to promote energy efficiency and conservation. This paper provides an overview of energy efficiency options presented by IPCC, the current energy efficiency governance structure at global level, and efforts taken at supranational and national levels, and makes suggestions for a governance framework.

This publication further develops the analysis presented in the India chapter of Energy Technology Perspectives 2010 and provides insights on the implications of achieving deep energy and CO2 emission cuts in the industrial sector both for India and globally. It investigates the least-cost combination of options that can significantly reduce energy and CO2 emissions in India's industrial sector, while enabling the Indian economy to continue to grow and alleviate energy poverty. For India to play its part in helping to realise deep cuts in global CO2 emissions by the middle of the 21st century, it will need to achieve rapid economic development over the next 40 years with only a very small increase in emissions. Currently there is no precedent for such a low-CO2 development path. The challenge for India will be to achieve strong economic growth while improving energy security, but without locking in high emissions.
Full Text Available This paper has as main objective to emphasize the importance of a permanent control activity on the economic concentration operations. In order to assure an appropriate choice as concern the economic concentration to be submitted at the assessment procedure each country has its competence to establish its turnover ceilings opening the procedure in accordance with the priorities of its own economic policy. As a final conclusion, we stress that economic concentration assessment and competition policy as a whole are very dynamic activities asking permanent legal and procedural adjustments in order to take appropriately into account economic interests of the country as well as the evolutions registered on regional and global level. This approach is the most valid in the case of Romania taking into account its recent accession to the European Union and its more and more important involvement in the regional and global cooperation.

The key dynamics of the magnetotail have been researched for decades and have been associated with either three-dimensional (3-D) plasma instabilities and/or magnetic reconnection. We apply a global hybrid-Vlasov code, Vlasiator, to simulate reconnection self-consistently in the ion kinetic scales in the noon-midnight meridional plane, including both dayside and nightside reconnection regions within the same simulation box. Our simulation represents a numerical experiment, which turns off the 3-D instabilities but models ion-scale reconnection physically accurately in 2-D. We demonstrate that many known tail dynamics are present in the simulation without a full description of 3-D instabilities or without the detailed description of the electrons. While multiple reconnection sites can coexist in the plasma sheet, one reconnection point can start a global reconfiguration process, in which magnetic field lines become detached and a plasmoid is released. As the simulation run features temporally steady solar wind input, this global reconfiguration is not associated with sudden changes in the solar wind. Further, we show that lobe density variations originating from dayside reconnection may play an important role in stabilising tail reconnection.

The economics of global warming is reviewed with special emphasis on how the cost depends on the discount rate and on how costs in poor and rich regions are aggregated into a global cost estimate. Both of these factors depend on the assumptions made concerning the underlying utility and welfare functions. It is common to aggregate welfare gains and losses across generations and countries as if the utility of money were constant, but it is not. If we assume that a CO 2 -equivalent doubling implies costs equal to 1.5% of the income in both high and low income countries, a pure rate of time preference equal to zero, and a utility function which is logarithmic in income, then the marginal cost of CO 2 emissions is estimated at 260-590 USD/ton C for a time horizon in the range 300-1000 years, an estimate which is large enough to justify significant reductions of CO 2 emissions on purely economic grounds. The estimate is approximately 50-100-times larger than the estimate made by Nordhaus in his DICE model and the difference is almost completely due to the choice of discount rate and the weight given to the costs in the developing world as well as a more accurate model of the carbon cycle. Finally, the sensitivity of the marginal cost estimate with respect to several parameters is analyzed
Full Text Available Forest communities dominated by noble broad-leaved trees (maple, lime and ash in Europe are of elevated scientific and conservation interest for the European Union. In this paper, we first present a synthesis of the maple and ash forests in peninsular Italy. By classifying these forests, we distinguish seven main groups for the territory, which only broadly match the syntaxa proposed in the literature. The variability of the Apennine data is then analysed floristically and phytogeographically (using chorological components in a central-southern European context, using numerical classification, INSPAN, and direct ordination of several synoptic tables. These analyses allow us to identify six different groups of European Acer-Fraxinus communities. Canonical Variates Analysis (CVA of the geographical components confirms the existence of distinct phytogeographical groups. In particular, we highlight the clear distinction between central European (including the Alps and southern European coenoses. Among the latter there was a clear floristic and chorological distinction between Balkan and Apennine groups. These results reflect the biogeographical subdivisions of Europe, but do not support the syntaxonomical schemes proposed by other authors, which are based only on floristic-ecological information or (recently use a smaller data set of Italian relevés. This study also shows that syntaxonomical schemes above the association level should pay more attention to phytogeographical aspects rather than focus on floristic-ecological information alone, in order to propose models that are of value on a geographical scale.

Brucellosis is a common and chronic disease of cattle and other bovids that often causes reproductive disorders. Natural infection in cattle is caused by Brucella abortus and transmission typically occurs during abortions, calving, or nursing. Brucellosis is also a major zoonotic disease due to contamination of dairy products or contact with the tissues of infected animals. Brucellosis has been eradicated from most of the developed world in the last 40 years but persists in many regions-the disease remains prevalent in portions of Africa, the Middle East, Asia, and Central and South America, as well as in the Mediterranean basin. In Italy, B. abortus has persisted in southern regions in both cattle and water buffalo. Previous attempts at analyzing the phylogenetics of B. abortus in Italy have been challenging due to limited genetic variability and unresolved global population genetic structure of this pathogen. We conducted genome-wide phylogenetic analyses on 11 representative strains of B. abortus from Italy, and compared these sequences to a worldwide collection of publically available genomes. Italian isolates belong to three clades that are basal to the main and global B. abortus lineage. Using six SNP-based assays designed to identify substructure within the Italian clades, we surveyed a collection of 261 isolates and found that one clade predominates throughout endemic districts in the country, while the other two clades are more geographically restricted to portions of southern Italy. Although related strains exist worldwide, B. abortus isolates from Italy are substantially different than those found in much of the rest of Europe and North America, and are more closely related to strains from the Middle East and Asia. Our assays targeting genetic substructure within Italy allowed us to identify the major lineages quickly and inexpensively, without having to generate whole genome sequences for a large isolate collection. These findings highlight the

Changes to sources, stressors, habitats, and geographic ranges; toxicological effects; end points; and uncertainty estimation require significant changes in the implementation of ecological risk assessment (ERA). Because of the lack of analog systems and circumstances in historically studied sites, there is a likelihood of type III error. As a first step, the authors propose a decision key to aid managers and risk assessors in determining when and to what extent climate change should be incorporated. Next, when global climate change is an important factor, the authors recommend seven critical changes to ERA. First, develop conceptual cause-effect diagrams that consider relevant management decisions as well as appropriate spatial and temporal scales to include both direct and indirect effects of climate change and the stressor of management interest. Second, develop assessment end points that are expressed as ecosystem services. Third, evaluate multiple stressors and nonlinear responses-include the chemicals and the stressors related to climate change. Fourth, estimate how climate change will affect or modify management options as the impacts become manifest. Fifth, consider the direction and rate of change relative to management objectives, recognizing that both positive and negative outcomes can occur. Sixth, determine the major drivers of uncertainty, estimating and bounding stochastic uncertainty spatially, temporally, and progressively. Seventh, plan for adaptive management to account for changing environmental conditions and consequent changes to ecosystem services. Good communication is essential for making risk-related information understandable and useful for managers and stakeholders to implement a successful risk-assessment and decision-making process.

Many of medical anthropology's most pressing research questions require an understanding how infections, money, and ideas move around the globe. The Global Polio Eradication Initiative (GPEI) is a $9 billion project that has delivered 20 billion doses of oral polio vaccine in campaigns across the world. With its array of global activities, it cannot be comprehensively explored by the traditional anthropological method of research at one field site. This article describes an ethnographic study of the GPEI, a collaborative effort between researchers at eight sites in seven countries. We developed a methodology grounded in nuanced understandings of local context but structured to allow analysis of global trends. Here, we examine polio vaccine acceptance and refusal to understand how global phenomena-in this case, policy decisions by donors and global health organizations to support vaccination campaigns rather than building health systems-shape local behavior. © 2016 by the American Anthropological Association.

Floristic compositions of non-endemic plants of continental islands were related to the neighboring continents because non-endemic plant species had historically migrated to continental islands from source areas. This study attempts to identify source areas of a continental island by means of floristic analysis and to assess possible migration routes on the basis of geographical distribution ranges of plants. Large quantities of angiosperm data records were downloaded from the Global Biodiversity Information Facility (GBIF). Similarity index and cluster analysis were used to identify the floristic similarities among 22 geographical localities of Taiwan (GLTs) and 34 terrestrial ecoregions in Asia. Geographical distribution ranges of non-endemic angiosperm species in Taiwan (NEASTs) were evaluated to mirror the possible migration routes from different source areas to Taiwan. There are 3275 angiosperm species in Taiwan derived from the dataset of GBIF. Among them, 847 are endemic and 2428 are NEASTs. Geographical distribution ranges of the 2428 NEASTs were categorized into 7 distribution groups. They were widely distribution from equator to Siberia (27 species), tropical ecoregions (345 species), tropical and subtropical ecoregions (663 species), tropical to temperate ecoregions (591 species), subtropical ecoregions (265 species), subtropical to temperate ecoregions (387 species), and temperate ecoregions (150 species). Results of similarity indices and cluster analysis demonstrated that high floristic similarities were observed among GLTs at lowland and southern Taiwan and tropical and subtropical ecoregions in Asia. GLTs at high mountains were assumed to have floristic similarity with temperate ecoregions in Asia, whereas the assumption was not supported by our analysis. It is partly because of that angiosperms with tropical and subtropical distributions extend their ranges from low to high elevations in Taiwan. Subtropical ecoregions at southern China and tropical

The 'crisis in human resources' in the health sector has been described as one of the most pressing global health issues of our time. The World Health Organization (WHO) estimates that the world faces a global shortage of almost 4.3 million doctors, midwives, nurses, and other healthcare professionals. A global undersupply of these threatens the quality and sustainability of health systems worldwide. This undersupply is concurrent with globalization and the resulting liberalization of markets, which allow health workers to offer their services in countries other than those of their origin. The opportunities of health workers to seek employment abroad has led to a complex migration pattern, characterized by a flow of health professionals from low- to high-income countries. This global migration pattern has sparked a broad international debate about the consequences for health systems worldwide, including questions about sustainability, justice, and global social accountabilities. This article provides a review of this phenomenon and gives an overview of the current scope of health workforce migration patterns. It further focuses on the scientific discourse regarding health workforce migration and its effects on both high- and low-income countries in an interdependent world. The article also reviews the internal and external factors that fuel health worker migration and illustrates how health workforce migration is a classic global health issue of our time. Accordingly, it elaborates on the international community's approach to solving the workforce crisis, focusing in particular on the WHO Code of Practice, established in 2010.

Full Text Available The task of identifying named entities from the discussion texts in Web forums faces the challenge of noisy names. As the names are often misspelled or abbreviated, the conventional techniques have failed to detect the noisy names properly. In this paper we propose a global context based framework for handling the noisy names. The framework is tested on a named entity recognition system designed to identify the names from the discussion texts in a homeopathy diagnosis discussion forum. The proposed global context-based framework is found to be effective in improving the accuracy of the named entity recognition system.
Full Text Available To complement this Special Feature on global water governance, we focused on a generic challenge at the global level, namely, the degree to which water issues need to be dealt with in a centralized, concentrated, and hierarchical manner. We examined water ecosystem services and their impact on human well-being, the role of policies, indirect and direct drivers in influencing these services, and the administrative level(s at which the provision of services and potential trade-offs can be dealt with. We applied a politics of scale perspective to understand motivations for defining a problem at the global or local level and show that the multilevel approach to water governance is evolving and inevitable. We argue that a centralized overarching governance system for water is unlikely and possibly undesirable; however, there is a need for a high-level think tank and leadership to develop a cosmopolitan perspective to promote sustainable water development.

Prior to the growing season of 1980, the floristic/vegetational studies involved an area covering more than 120 square miles having several major soil and vegetation types. 1980 studies concentrated on a few square miles surrounding ERDA 9. The goal of the 1980 work was to obtain as much additional floristic data as possible, in part to determine if the summer flora could recover from the prolonged summer dry spell to provide a significant fall flora. Another goal was to assess the fall vegetation in terms of taxa present during this season as well as distribution, density and phenology of these taxa. Special attention was given to measuring the acorn biomass on shinnery oak (Quercus havardii) because this is an important component of the late summer and autumn food chain and may influence small mammal densities. The flora of the 1980 growing season showed considerable variation from more typical or normal flora at the WIPP site. Lack of rainfall at the opportune time and lower than normal temperatures account for this variation

Environmental mercury (Hg) contamination is an urgent global health threat. The complexity of Hg in the environment can hinder accurate determination of ecological and human health risks, particularly within the context of the rapid global changes that are altering many ecological processes, socioeconomic patterns, and other factors like infectious disease incidence, which can affect Hg exposures and health outcomes. However, the success of global Hg-reduction efforts depends on accurate assessments of their effectiveness in reducing health risks. In this paper, we examine the role that key extrinsic and intrinsic drivers play on several aspects of Hg risk to humans and organisms in the environment. We do so within three key domains of ecological and human health risk. First, we examine how extrinsic global change drivers influence pathways of Hg bioaccumulation and biomagnification through food webs. Next, we describe how extrinsic socioeconomic drivers at a global scale, and intrinsic individual-level drivers, influence human Hg exposure. Finally, we address how the adverse health effects of Hg in humans and wildlife are modulated by a range of extrinsic and intrinsic drivers within the context of rapid global change. Incorporating components of these three domains into research and monitoring will facilitate a more holistic understanding of how ecological and societal drivers interact to influence Hg health risks.
Full Text Available Recently, many researchers have been dedicated to using convolutional neural networks (CNNs to extract global-context features (GCFs for remote-sensing scene classification. Commonly, accurate classification of scenes requires knowledge about both the global context and local objects. However, unlike the natural images in which the objects cover most of the image, objects in remote-sensing images are generally small and decentralized. Thus, it is hard for vanilla CNNs to focus on both global context and small local objects. To address this issue, this paper proposes a novel end-to-end CNN by integrating the GCFs and local-object-level features (LOFs. The proposed network includes two branches, the local object branch (LOB and global semantic branch (GSB, which are used to generate the LOFs and GCFs, respectively. Then, the concatenation of features extracted from the two branches allows our method to be more discriminative in scene classification. Three challenging benchmark remote-sensing datasets were extensively experimented on; the proposed approach outperformed the existing scene classification methods and achieved state-of-the-art results for all three datasets.
Full Text Available This paper reviews information from the existing literature and the EU GMOS (Global Mercury Observation System project to assess the current scientific knowledge on global mercury releases into the atmosphere, on global atmospheric transport and deposition, and on the linkage between environmental contamination and potential impacts on human health. The review concludes that assessment of global sources and pathways of mercury in the context of human health is important for being able to monitor the effects from implementation of the Minamata Convention targets, although new research is needed on the improvement of emission inventory data, the chemical and physical behaviour of mercury in the atmosphere, the improvement of monitoring network data, predictions of future emissions and speciation, and on the subsequent effects on the environment, human health, as well as the economic costs and benefits of reducing these aspects.

Full Text Available The paper presents the transformations of species composition in the main plant communities of the Karkonosze Mts. subalpine and alpine belts during the last 35 years. The investigations of floristic changes were performed in associations: Carici (rigidae-Nardetum, Carici-Festucetum supinae, Crepidi-Calamagrostietum villose and Empetro-Vaccinietum. Signalized are also some vegetation transformations in the remaining belts. The progressing floristic degradation of plant communities in the subalpine and alpine belts consists in: (a expansion of grasses, (b decline of rare vascular plants, and (c elimination of terricolous bryophytes and lichens. In spruce forest belts declining are species connected with old-growth spruce forests like: Listera cordata and Moneses uniflora. The changes of plant communities of low mountain swards (Nardetalia caused by cessation of pasture and mowing in the cause of retreat of many rare plants, like e.g., Arnica montana. The main cause of the still lasting in the Karkonosze Mts. community transformations is the changes in soil environment connected with anthropogenic nitrogen fertilization. The large inflow of mineral nitrogen from the atmosphere (1138 mg/m2 sum for vegetation season is the reason of accelerated rate of decomposition of organic matter and intensified nitrification. The high content of nitrates in soil (5 times higher than in the Tatra Mts. swards is the reason of expansion of graminoids, mainly Deschampsia flexuosa, Calamagrostis villosa and Carex bigelowii subsp. rigida. The overfertilisation of habitats causes the retreat of rare high mountain vascular plants and the decline of terricolous bryophytes and lichens.

A glance through the Harvard Business Review reveals many suggestions and research pieces reviewing sales and marketing techniques. Most educators will be familiar with the notion that making accurate first impressions and being responsive, whilst maintaining pace is critical to engaging an audience. There are lessons to be learnt from industry that can significantly impact upon our teaching. Eisenkraft, in his address to the NSTA, proposed four essential questions. This presentation explores one of those questions: 'Why should I care?', and discusses why this question is crucial for engaging students by giving a clear purpose for developing their scientific understanding. Additionally, this presentation explores how The ISF Academy has adapted the NGSS, using the 14 Grand Engineering Challenges and the IB MYP, to provide current, authentic global contexts, in order to give credibility to the concepts, understandings and skills being learnt. The provision of global contexts across units and within lessons supports a platform for students to have the freedom to explore their own sense of social responsibility. The Science Department believes that planning lessons with tasks that elaborate on the student's new conceptualisations, has helped to transfer the student's new understanding into social behavior beyond the classroom. Furthermore, extension tasks have been used to transfer conceptual understanding between different global contexts.

Understanding modern and historical global changes requires interdisciplinary knowledge of the physical and life sciences. The Understanding Global Change website from the UC Museum of Paleontology will use a focal infographic that unifies diverse content often taught in separate K-12 science units. This visualization tool provides scientists with a structure for presenting research within the broad context of global change, and supports educators with a framework for teaching and assessing student understanding of complex global change processes. This new approach to teaching the science of global change is currently being piloted and refined based on feedback from educators and scientists in anticipation of a 2016 website launch. Global change concepts are categorized within the infographic as causes of global change (e.g., burning of fossil fuels, volcanism), ongoing Earth system processes (e.g., ocean circulation, the greenhouse effect), and the changes scientists measure in Earth's physical and biological systems (e.g., temperature, extinctions/radiations). The infographic will appear on all website content pages and provides a template for the creation of flowcharts, which are conceptual models that allow teachers and students to visualize the interdependencies and feedbacks among processes in the atmosphere, hydrosphere, biosphere, and geosphere. The development of this resource is timely given that the newly adopted Next Generation Science Standards emphasize cross-cutting concepts, including model building, and Earth system science. Flowchart activities will be available on the website to scaffold inquiry-based lessons, determine student preconceptions, and assess student content knowledge. The infographic has already served as a learning and evaluation tool during professional development workshops at UC Berkeley, Stanford University, and the Smithsonian National Museum of Natural History. At these workshops, scientists and educators used the infographic

Full Text Available The fall of the communist regime and the demise of the bipolar political order have been factors for the development of globalizing connections on the levels of the urban systems in Central and East-European states. The main social impact of this complex phenomenon is the expansion of the diffusion area for the products of global consumerism, which involves the development and the diversification of commercial services. Their localization is still a direct consequence of financial segregation; the determining agent for the degree of penetration of global consumer goods at a local level is the localization of banking investments. Considering this context, this article is correlatively analyzing localization and dispersion factors for financial (banks and banking units and commercial services (malls, international networks of hyper- and supermarkets, restaurants etc., having as case studies the Romanian urban system at a larger scale and its capital city at a micro scale.

Bayesian statistics offers a well-founded and powerful fusion methodology also for the fusion of heterogeneous information sources. However, except in special cases, the needed posterior distribution is not analytically derivable. As consequence, Bayesian fusion may cause unacceptably high computational and storage costs in practice. Local Bayesian fusion approaches aim at reducing the complexity of the Bayesian fusion methodology significantly. This is done by concentrating the actual Bayesian fusion on the potentially most task relevant parts of the domain of the Properties of Interest. Our research on these approaches is motivated by an analogy to criminal investigations where criminalists pursue clues also only locally. This publication follows previous publications on a special local Bayesian fusion technique called focussed Bayesian fusion. Here, the actual calculation of the posterior distribution gets completely restricted to a suitably chosen local context. By this, the global posterior distribution is not completely determined. Strategies for using the results of a focussed Bayesian analysis appropriately are needed. In this publication, we primarily contrast different ways of embedding the results of focussed Bayesian fusion explicitly into a global context. To obtain a unique global posterior distribution, we analyze the application of the Maximum Entropy Principle that has been shown to be successfully applicable in metrology and in different other areas. To address the special need for making further decisions subsequently to the actual fusion task, we further analyze criteria for decision making under partial information.
Full Text Available Floristic databases constitute the second level of plant information systems, after taxonomic-nomenclatural databases. This paper provided the details of data structure and available data resources to develop a floristic database, along with some explanations on taxonomic and floristic databases. Also, this paper proposed the availability and possibility of a shortcut to constructing a national floristic database through uniforming and compilation of dispersed floristic data contained in various botanical centers of Iran. Therefore, Iran could be the second country in SW Asia region to have a national floristic database, and the resulted services can be presented to national scientific community.
Immigrants depend on within-group social networks for social support during the acculturation process. Within-group social networks are linked to higher mutual concern and reciprocity, lower acculturative stress, and lower depression among immigrants Studies are limited, however, about immigrants' social support in the contexts of global connectedness and transnational connectivity. Grounded in social capital approach and immigrant health framework, this qualitative, community-based study examined the social networks of immigrant men from India to New York City. Drawing upon the participants' narratives, the author illustrates the ways that social capital influences social networking and acculturative stress in post-immigration sociocultural contexts along with its implications for community-based interventions.

The emergence of the modern styles of capoeira should be considered in the global context of the modernization of martial arts currently in progress in Europe and Asia on the one hand, and the new phase of Afro-descendant modernity on the other. The confrontation between the capoeira, jiu-jitsu and other martial arts circles led mestre Bimba to develop his regional Bahian fighting style. The revival of traditional capoeira as Angolan capoeira led by mestre Pastinha is part of the broader movement of affirmation of Afro-Bahian culture in Salvador and the growing visibility of the Afro-descendant body in the Atlantic world.

Alcohol consumption is responsible for 3.3 million deaths globally or nearly 6% of all deaths. Alcohol use contributes to both communicable and noncommunicable diseases, as well as violence and injuries. The purpose of this review is to discuss, in the context of the expansion of transnational alcohol corporations and harms associated with alcohol use, policy options for regulating exposure to alcohol marketing. We first provide an overview of the public health problem of harmful alcohol consumption and describe the association between exposure to alcohol marketing and alcohol consumption. We then discuss the growth and concentration of global alcohol corporations and their marketing practices in low- and middle-income countries, as well as in higher-income societies. We review the use and effectiveness of various approaches for regulating alcohol marketing in various countries before discussing challenges and opportunities to protect public health.

The aims of the present study were to: (1) investigate whether CORINE land cover classes reflect significant differences in floristic composition, using a very detailed CORINE land cover map (scale 1:5000); (2) decompose the relationships between floristic assemblages and three groups of explanatory variables (CORINE land cover classes, environmental characteristics and spatial structure) into unique and interactive components. Stratified sampling was used to select a set of 100-m(2) plots in each land cover class identified in the semi-natural wetland surrounding a lake in central Italy. The following six classes were considered: stable meadows, deciduous oak dominated woods, hygrophilous broadleaf dominated woods, heaths and shrublands, inland swamps, canals or watercourses. The relationship between land cover classes and floristic composition was tested using several statistical techniques in order to determine whether the results remained consistent with different procedures. The variation partitioning approach was applied to identify the relative importance of three groups of explanatory variables in relation to floristic variation. The most important predictor was land cover, which explained 20.7% of the variation in plant distribution, although the hypothesis that each land cover class could be associated with a particular floristic pattern was not verified. Multi Response Permutation Analysis did not indicate a strong floristic separability between land cover classes and only 9.5% of species showed a significant indicator value for a specific land cover class. We suggest that land cover classes linked with hygrophilous and herbaceous communities in a wetland may have floristic patterns that vary with fine scale and are not compatible with a land cover map.

Full Text Available Interactions of the national and the global in economic transformations occurring in open economic systems are substantiated. Conceptual approaches to the development of economic systems in the globalization and regionalization context are summed up. It is shown that globalization is a logical consequence of mutual influences and interactions of multiple local transformations in socio-economic systems of various levels, which planetary self-organization generates the new quality of the global economic development. It is concluded that globalization has controversial impact on the transformation capacities of national economic systems that have to operate in the unfavorable condition of the growing instability of the global economic system and rapid integration in the structures with already established economic relations. The heuristic and experimental nature of economic and institutional transformations in these countries is added by splits of national economic systems and disruptions of established production links; the outstripping liberalization of foreign economic relations, creating rather external than internal pressures on national manufacturers and making them less capable to adapt to the competitive environment; the accelerated liberalization of monetary and financial systems, opening up ways to reallocation of capital from the sluggish real sector to the more flexible sector of transactions with currencies and securities; the shrinking regulatory authorities of national governments with respect of trade, competition, tax policies or social welfare; the growing domination of TNC and outflow of productive resources from national economies, important for their self-development, thus making their economic systems structurally primitive; the sharp property differentiation within societies and the increasing shares of population with low incomes.

Full Text Available In the article author is about to maintain that discussion on regionalization asks for contextualisation within the currents of actual geopolitics, on the one hand, and wider process of globalisation and unification, on the other. In keeping with this, author in the first part deals with globalizing integrative processes with special attention played to the problem of nation-state survival. Point of analysis is given in the ambivalence of sovereignty: the very concept becomes outdated on the local level, but by the same token it is fully affirmed on the global level. On the global level we are encountered with revival of the classical concept of sovereignty. Problem of regionalization, in the second part of the article, is reconsidered as a phenomenon that is taking place between those two currents. Author maintains two related theses. First, designs of the regionalization less dependent of the authority of given state for they fall under the jurisdiction of global superpower and becomes dependant of its geostrategic planes and political demands. Second, that main reasons for Democratic Opposition of Serbia to work in favor of regionalization as a synonym for democracy is in lack of solid democratic reform and need to entrench itself in the precomposed structure of social and economic power. In this context one could forsake that we in Serbia are confronted with bright prospects of democracy at the cost of the 'hollowing out' of the state as main guarantee of it.

Human action recognition in 3D skeleton sequences has attracted a lot of research attention. Recently, Long Short-Term Memory (LSTM) networks have shown promising performance in this task due to their strengths in modeling the dependencies and dynamics in sequential data. As not all skeletal joints are informative for action recognition, and the irrelevant joints often bring noise which can degrade the performance, we need to pay more attention to the informative ones. However, the original LSTM network does not have explicit attention ability. In this paper, we propose a new class of LSTM network, Global Context-Aware Attention LSTM (GCA-LSTM), for skeleton based action recognition. This network is capable of selectively focusing on the informative joints in each frame of each skeleton sequence by using a global context memory cell. To further improve the attention capability of our network, we also introduce a recurrent attention mechanism, with which the attention performance of the network can be enhanced progressively. Moreover, we propose a stepwise training scheme in order to train our network effectively. Our approach achieves state-of-the-art performance on five challenging benchmark datasets for skeleton based action recognition.

Full Text Available Health and wellbeing are determined by a number of complex, interrelated factors. The application of design thinking to questions around health may prove valuable and complement existing approaches. A number of public health projects utilizing human centered design (HCD, or design thinking, have recently emerged, but no synthesis of the literature around these exists. The results of a scoping review of current research on human centered design for health outcomes are presented. The review aimed to understand why and how HCD can be valuable in the contexts of health related research. Results identified pertinent literature as well as gaps in information on the use of HCD for public health research, design, implementation and evaluation. A variety of contexts were identified in which design has been used for health. Global health and design thinking have different underlying conceptual models and terminology, creating some inherent tensions, which could be overcome through clear communication and documentation in collaborative projects. The review concludes with lessons learned from the review on how future projects can better integrate design thinking with global health research.

Full Text Available This paper discusses some of the problems associated with search and digital-rights management in the emerging age of interconnectivity. An open-source system called Context Driven Topologies (CDT is proposed to create one global context of geography, knowledge domains, and Internet addresses, using centralized spatial databases, geometry, and maps. The same concept can be described by different words, the same image can be interpreted a thousand ways by every viewer, but mathematics is a set of rules to ensure that certain relationships or sequences will be precisely regenerated. Therefore, unlike most of today’s digital records, CDTs are based on mathematics first, images second, words last. The aim is to permanently link the highest quality events, artifacts, ideas, and information into one record documenting the quickest paths to the most relevant information for specific data, users, and tasks. A model demonstration project using CDT to organize, search, and place information in new contexts while protecting the authors’ intent is also introduced.
Full Text Available In recent years, as a result of the hastening economic crisis, the Romanian business environment has known important changes. This paper presents and analyzes the changes caused by globalization in small and medium enterprises that exports goods and services from Bucharest. The purpose of the research was to discover the impact of global crisis upon the concerned group of enterprises and the organizational changes implemented by them. Through the research we succeeded to identify the main problems that occurred in the target group enterprises in the context of global economic crisis and what caused the reduction in their developing rhythm. Another part of the paper contains an analysis of the managers perceptions regarding the governmental anti-crisis measures and strategic and tactical changes initiated by them as a natural need to adapt to the particularities of the internal and international business environment. The final part includes the conclusions of the research and a sum of recommendations for efficient management of organizational changes in target group enterprises, with the possibility of generalizing them to all Romanian small and medium enterprises.

Recent assessments by the International Union for Conservation of Nature (IUCN) indicate the existence of about 612 recognized primate species and subspecies (IUCN RedList, 2012), but close to 50% of these taxa are at risk of extinction as a result of human action. In this article, I call attention to underlying regional and global socioeconomic contexts of primate conservation. Using information from FAO and UN databases and other sources, I examine, for the Neotropics, sub-Saharan Africa, and Southeast Asia, trends in forest loss and human demographics and social condition, discuss the impact of global market pressures upon primate habitats, and examine land-use patterns that may favor primate conservation. Between 1990 and 2010, an estimated 149 million ha of forest were lost in the three regions and additional losses are expected in the future. Global human population will increase from 7 billion in 2012 to 9 billion in 2050. Currently, 2 billion people live in the three primate range regions under high levels of poverty. Large-scale deforestation is related to global market demands, especially from developed and developing nations, for food (e.g., cattle), domestic animal feed (e.g., soybeans), biofuel-based crops (e.g., oil palm), and industrial round wood. The growth of protected areas in the three regions has been steady for several decades, but it is not enough to ensure long-term conservation of many primate taxa. Other conservations tools involving sustainable land use and biodiversity conservation corridors are required at the landscape level. The above assessment can easily be applied at the local level by primatologists, giving more precision to conservation initiatives. © 2012 Wiley Periodicals, Inc.

Similarities between the floras of geographically comparable regions of New Zealand (NZ) and the southern Andes (SA) have interested biologists for over 150 years. The present work selects vegetation types that are physiognomically similar between the two regions, compares their floristic composition, assesses the environmental factors that characterize these matching vegetation types, and determines whether phylogenetic groups of ancestral versus modern origin are represented in different proportions in their floras, in the context of their biogeographic history. Floristic relationships based on 369 genera of ten vegetation types present in both regions were investigated with correspondence analysis (CA) and ascending hierarchical clustering (AHC). The resulting ordination and classification were related to the environmental characteristics of the different vegetation types. The proportions of different phylogenetic groups between the regions (NZ, SA) were also compared, and between forest and non-forest communities. Floristic similarities between NZ and SA tend to increase from forest to non-forest vegetation, and are highest in coastal vegetation and bog. The floras of NZ and SA also differ in their phylogenetic origin, NZ being characterized by an 'excess' of genera of basal origin, especially in forests. The relatively low similarities between forests of SA and NZ are related to the former being largely of in situ South American and Gondwanan origin, whereas the latter have been mostly reconstituted though transoceanic dispersal of propagules since the Oligocene. The greater similarities among non-forest plant communities of the two regions result from varied dispersal routes, including relatively recent transoceanic dispersal for coastal vegetation, possible dispersal via a still-vegetated Antarctica especially for bog plants, and independent immigration from Northern Hemisphere sources for many genera of alpine vegetation and grassland.
Full Text Available Abstract. Study on the species composition of vascular plants in 'Chinarite' protected area in Belashtitsa village, Rodopi Municipality, Bulgaria was conducted using the floristic analysis method. A total of 147 species of vascular plants were identified, belonging to 124 genera and 51 families. The families Poaceae, Asteraceae, Lamiaceae, Brassicaceae, Apiaceae, Rosaceae and Fabaceae are the most highly represented. The comparative analysis shows that the angiosperm taxa are dominating in the studied area. Dicotyledonous plants are prevailing among them, while monocotyledonous are significantly less in number. Molinia caerulea species, identified in the present study, has not been reported to have been found so far in the Thracian lowland floristic region.

Annual resolution reconstructions of alpine temperatures are rare, particularly for the Southern Hemisphere, while no snow cover reconstructions exist. These records are essential to place in context the impact of anthropogenic global warming against historical major natural climate events such as the Roman Warm Period (RWP), Medieval Climate Anomaly (MCA) and Little Ice Age (LIA). Here we show for a marginal alpine region of Australia using a carbon isotope speleothem reconstruction, warming over the past five decades has experienced equivalent magnitude of temperature change and snow cover decline to the RWP and MCA. The current rate of warming is unmatched for the past 2000 years and seasonal snow cover is at a minimum. On scales of several decades, mean maximum temperatures have undergone considerable change ≈ ± 0.8 °C highlighting local scale susceptibility to rapid temperature change, evidence of which is often masked in regional to hemisphere scale temperature reconstructions.

Full Text Available Energy is one of the most important elements of the global economy, being the basic unit of world economic development. In the energy mix, nuclear energy - more than any other type of energy - has generated and will always generate a series of controversies. This article aims to emphasize the economic and social implications, further than the general purpose of developing nuclear energy: national energetic security. With the starting point clearly defined – the history already written by the operation of Unit 1 and 2 – the path to discover all its elements seems to be clear, although a whole range of unknown issues can rise many different interpretations. In Romania, nuclear energy produces 18% of Romania's electricity supplies. Development of Units 3 and 4 of the Cernavoda site could more than double this capacity. This will have major implications in the trading market, significantly influencing the price of electricity not only nationally, but, in the context coupling energy markets, as well as at regional level. It is also risen the question of using this additional production. Depending on the time of commissioning, this quantity of energy that now seems overmuch, can be used for export, to reduce the use of fossil fuels and to continue to obtain electricity in the context of a system based on power plants that use fossil fuels, whose lifespan is nearing completion.
In a general hospital (Hôtel-Dieu, in the center of Paris), run with a global budget, budgets determined for each unit were introduced as an experiment in 1980. Physicians were in charge of certain expenses, mainly: linen, drugs, transportation of patients to and from other hospitals within Paris, and blood fractions. The whole does not exceed 4% of the turnover (FF 20 millions in 1980) of a 67 bed internal medicine unit. Other accounts deal with the stays, admissions, prescriptions of technical acts, laboratory analyses, and X-rays. In 1980, expenses were 11% more than budgeted, but the increase in stays and particularly in admissions was significantly greater. The resulting savings were 8.8% and 18.7% for stays and admissions respectively. Psychic reactions were variable. The subsequent budgets followed the fluctuations of recorded expenses, which were fairly important in both directions. The unit budget may be an advance or a regression, in a restrictive and past-perpetuating context. The coherence between the unit budget and the global hospital budget is questionable. Physicians were willing to take part in accounting and saving. They have good reason for not enlarging their financial responsibilities. Conversely, they may give more attention to diseases of public opinion.

Full Text Available The aim of this study is to consider a new understanding of the complex and multilayered structure of Ankara music, which is situated between tradition and modernity and has become an important form of popular culture in the region, in the context of local and global relationships.. The theoretical framework of the study is based on Appadurai’s “global cultural flow” model. The ethnoscape, finanscape, mediascape, technoscape and ideoscape of Ankara music is examined in accordance with this approach to reveal the dynamics that make this music different. In the light of these findings, it is concluded that the ethnoscape of Ankara music is based on a broad demographic coalition that has created an independent music industry with a finanscape depending on production, distribution and consumption. While this type of music is represented through a network-based social structure, it gains legitimacy outside its bounds within the media environment. The “Ankara” genre and its quest for authenticity described in this work reveal the ideoscape of the new Ankara music.

Himalayas are globally important biodiversity hotspots and are facing rapid loss in floristic diversity and changing pattern of vegetation due to various biotic and abiotic factors. This has necessitated the qualitative and quantitative assessment of vegetation here. The present study was conducted in Sangla Valley of northwest Himalaya aiming to assess the structure of vegetation and its trend in the valley along the altitudinal gradient. In the forest and alpine zones of the valley, 15 communities were recorded. Study revealed 320 species belonging to 199 genera and 75 families. Asteraceae, Rosaceae, Apiaceae, and Ranunculaceae were dominant. Among genera, Artemisia followed by Polygonum, Saussurea, Berberis, and Thalictrum were dominant. Tree and shrub's density ranged from 205 to 600 and from 105 to 1030 individual per hectare, respectively, whereas herbs ranged from 22.08 to 78.95 individual/m(2). Nearly 182 species were native to the Himalaya. Maximum altitudinal distribution of few selected climate sensitive species was found to be highest in northeast and north aspects. This study gives an insight into the floristic diversity and community structure of the fragile Sangla Valley which was hitherto not available.
Full Text Available In recent years, the engagement of corporations in child trafficking has become a matter of growing importance. Many corporations have adopted global subcontracting systems and complex structures that boost their productivity and profits, but might also create more opportunities for trafficking and exploitation of both adults and children. Taking this context into account, the ways in which corporations can commit child trafficking will be explored and exemplified to highlight their diversity. This paper also offers a brief overview of the response given by international and European anti-trafficking instruments concerning corporate criminal liability for child trafficking. Moreover, the mechanisms adopted by some companies to prevent trafficking and promote transparency within their supply chains will also be addressed. Overall, this paper aims to illustrate the pivotal role of corporations from two perspectives: as potential perpetrators of this serious crime, and as necessary actors to prevent it. El compromiso empresarial sobre el tráfico infantil es un asunto de creciente importancia. Muchas corporaciones han adoptado sistemas globales de subcontrataciones y complejas estructuras que incrementan su productividad y sus beneficios, pero que también podrían crear más oportunidades para la trata y la explotación de adultos y niños. Partiendo de este contexto, se exploran y ejemplifican las diversas formas en que las corporaciones pueden cometer tráfico infantil. El artículo repasa brevemente la respuesta de los instrumentos internacionales y europeos en lo tocante a la responsabilidad penal de las corporaciones por la trata infantil, y aborda los mecanismos adoptados por algunas empresas para prevenir la trata y promover la transparencia en sus cadenas de suministro. En suma, se pretende ilustrar el rol crucial de las corporaciones desde dos puntos de vista: como potenciales perpetradores de este grave crimen y como actores necesarios

Full Text Available It suffices to browse the websites of only a few of the most noteworthy Romanian cultural organizations – including the website of the Ministry of Culture – to conclude that quality policies are missing. In fact, these are not the only policies that are missing, but this topic should be discussed in another paper. The objective of this paper is to analyze the progresses and the opportunities, as well as the problems and the challenges that the Romanian society and economy are facing as far as culture is concerned at the beginning of the new millennium, in the particular context of the global economic crisis: specifically, we will focus on the role of cultural organization managers in implementing quality management as the main factor in assuring the competitiveness needed to overcome the crisis. Cultural organization managers generally admit that a change is needed in order to cope with competitive pressure, but few understand how this change should be implemented. To avoid the issues associated with “change programs”, the management of cultural organizations must focus on the structure of processes, recognizing the roles and responsibilities of their employees in the processes in which they are involved.

The current study focuses on maternal cognitive capacities as determinants of parenting in a highly disadvantaged global context, where children's experiences at home are often the 1st and only opportunity for learning and intellectual growth. In a large sample of 1,291 biological mothers of preschool-aged children in rural Pakistan, we examined the unique association of maternal working memory skills (independent of related cognitive capacities) with cognitively stimulating parenting behaviors. Path analysis revealed that directly assessed working memory, short-term memory, and verbal intelligence independently predicted greater levels of observed maternal scaffolding behaviors. Mothers from poorer families demonstrated lower levels of working memory, short-term memory, and verbal intelligence. However, mothers' participation in an early childhood parenting intervention that ended 2 years prior to this study contributed to greater levels of working memory skills and verbal intelligence. Further, all 3 domains of maternal cognitive capacity mediated the effect of family economic resources on maternal scaffolding, and verbal intelligence also mediated the effect of early parenting intervention exposure on maternal scaffolding. The study demonstrates the unique relevance of maternal working memory for scaffolding behaviors that required continuously monitoring the child's engagement, providing assistance, and minimizing external distractions. These results highlight the importance of directly targeting maternal cognitive capacities in poor women with little or no formal education, using a 2-generation intervention approach that includes activities known to promote parental executive functioning and literacy.

Full Text Available The main objective of this article is to present the determinants of increase in agricultural commodity prices after 2006. The other specific aim is to show the factors affecting agricultural raw materials and food prices in the global context. This article is a review paper of the determinants of recent commodity and food prices spikes. However, it provides an outlook on these determinants that were the most important for the increases in the last decade. The last part of the article (conclusions to some extent is a synthesis of considerations and includes the authors’ opinions concerning determinants and an attempt to identify which ones were the most important in the growth of agricultural commodity prices. These increases in agricultural commodity prices resulted from many factors and it is very difficult to separate the individual impact of each of them, because they occurred in parallel. However, it is possible to indicate several main reasons for these price increases, which are: adverse changes in supply-demand relations in agricultural markets, increases in oil prices (and increases of the volatility of those prices, development of biofuel production from agricultural commodities (the first generation biofuels, dollar depreciation, an increase in operations of a speculative nature on commodity markets and improper economic policy that created an environment for the growth of prices of agricultural products.

Identifying Indigenous Peoples globally is complex and contested despite there being an estimated 370 million living in 70 countries. The specific context and use of locally relevant and clear definitions or characterizations of Indigenous Peoples is important for recognizing unique health risks Indigenous Peoples face, for understanding local Indigenous health aspirations and for reflecting on the need for culturally disaggregated data to plan meaningful research and health improvement programs. This paper explores perspectives on defining Indigenous Peoples and reflects on challenges in identifying Indigenous Peoples. Literature reviews and Internet searches were conducted, and some key experts were consulted. Pragmatic and political definitions by international institutions, including the United Nations, are presented as well as characterizations of Indigenous Peoples by governments and academic researchers. Assertions that Indigenous Peoples have about definitions of indigeneity are often related to maintenance of cultural integrity and sustainability of lifestyles. Described here are existing definitions and interests served by defining (or leaving undefined) such definitions, why there is no unified definition and implications of "too restrictive" a definition. Selected indigenous identities and dynamics are presented for North America, the Arctic, Australia and New Zealand, Latin America and the Caribbean, Asia and Africa. While health researchers need to understand the Indigenous Peoples with whom they work, ultimately, indigenous groups themselves best define how they wish to be viewed and identified for research purposes.

The review aims to give an update on the literature around traffic-related air pollution (TRAP) and allergic disease in the context of global urbanization, as the most populous countries in the world face severe TRAP exposure challenges. As research continues to show that gene-environment interactions and epigenetics contribute to the TRAP-allergy link, evidence around the links to climate change grows. Greenspace may provide a buffer to adverse effects of traffic on health, overall, but pose risks in terms of allergic disease. The link between traffic-related pollution and allergy continues to strengthen, in terms of supportive observational findings and mechanistic studies. Levels of TRAP across the world, particularly in Asia, continue to dramatically exceed acceptable levels, suggesting that the related adverse health consequences will accelerate. This could be counterbalanced by primary emission control and urban planning. Attention to combined effects of TRAP and allergen exposure is critical to avoiding misleading inferences drawn though examination only of isolated factors.

Full Text Available In the XIX century known as the „historical age”, a high degree of trust to history and social prestige of historical science relied on the entrenched in public consciousness the idea of continuity of historical development of a human civilization and, respectively, of the unique opportunities of the use of the past experience as a means to solve the problems of the present and to build „the bright future”. But the understanding of the dramatic experi-ence of the XX century undermined the belief in the “use of history”, and this situation has been greatly aggravated with intensification of the processes of globalization on the bor-der of XX and XXI centuries. The problems of interaction between “academic (professional history” and the wide public in the concrete societies and the changes in their relations in the context of deep social transformations proved to take place at the center of many re-searchers’ attention. Public history is purposefully overcoming the typical for historical science of the XX century alienation from „the uninitiated”; it strives to restore the interest of the consumer to the historians’ production, to propagate professional standards, histor-ical knowledge and proper understanding of the specific character of “historian’s craft” among the wide circles of the non-professionals.
Full Text Available Global migration is a topic of utmost importance in psychological research. As over 200 million people are on the move across national borders, and many more within their own countries, the processes of these migrations must be examined from different points of view and from different geographical locations. The articles in this special journal issue pointedly illustrate the role of international, national, community, and individual factors that shape these migrations. One cross-cutting theme is the importance of studying how multiple levels of context affect immigrant and migrant experiences. All six contributions, collectively, enrich the often individual-centric psychological literature. Issues of resilience and spaces of resistance emerged as a second cross-cutting theme, pointing to new directions for acculturation research and intervention. The challenge of recognizing diversity within migrant communities and among migration patterns is a third cross-cutting theme essential to address as we work toward a more equal world in which people can more freely chose whether to stay or leave their homes.

Economic efficiency tends to be an important argument when different means of environmental control are assessed and suggested. Considering that the most cost-efficient means are not the ones most frequently chosen and used, some other qualities seem to play an equally important role. I use findings from organisational theory and negotiation theory to better understand what is concealed in the black-box of decision-making and implementation. My empirical material consists of case studies of four different means of environmental control used in Sweden during the 1990s to mitigate the threat of global warming. These are an environmental tax, a licensing trial, municipal energy planning, and technology procurement. Each represents a particular discipline (economic, legal, physical planning, or technological) in which a context (planning or market) and an approach (traditional relay race or alternative process-oriented) are combined. Although each means has its particular niche, some qualities stand out as superior. Such means need to be divisible in space as well as in time. It is then easier to get started. Since it is just as easy to deviate from, rather than adhere to, the predetermined course after a while, some incentive must be given to the person in charge of implementation. In other words, the classic proverb of using sticks and carrots is still valid although it is not always taken to heart and practised. (Author)

The climate change research community's shared socioeconomic pathways (SSPs) are a set of alternative global development scenarios focused on mitigation of and adaptation to climate change. To use these scenarios as a global context that is relevant for policy guidance at regional and national levels, they have to be connected to an exploration of drivers and challenges informed by regional expertise. In this paper, we present scenarios for West Africa developed by regional stakeholders and quantified using two global economic models, GLOBIOM and IMPACT, in interaction with stakeholder-generated narratives and scenario trends and SSP assumptions. We present this process as an example of linking comparable scenarios across levels to increase coherence with global contexts, while presenting insights about the future of agriculture and food security under a range of future drivers including climate change. In these scenarios, strong economic development increases food security and agricultural development. The latter increases crop and livestock productivity leading to an expansion of agricultural area within the region while reducing the land expansion burden elsewhere. In the context of a global economy, West Africa remains a large consumer and producer of a selection of commodities. However, the growth in population coupled with rising incomes leads to increases in the region's imports. For West Africa, climate change is projected to have negative effects on both crop yields and grassland productivity, and a lack of investment may exacerbate these effects. Linking multi-stakeholder regional scenarios to the global SSPs ensures scenarios that are regionally appropriate and useful for policy development as evidenced in the case study, while allowing for a critical link to global contexts.

The number of reports on negative effects of air pollution on biodiversity is increasing. Here, examples from the literature are presented which concern effects of fluoride, deposition of nitrogen, and ozone. Today, nitrogen loads and levels of tropospheric ozone seem to be most relevant forms of air pollution affecting species diversity of the flora. Results from recent investigations of ozone effects at Liebefeld indicate that the loss of floristic diversity in permanent meadows is possible because of the high relative sensitivity of some typical species. Further studies will be necessary to validate the results obtained from experiment with single plants at the level of the intact plant community in the field, and to identify the critical level of ozone to protect the floristic biodiversity of meadows.

Full Text Available It is shown that, in the context of globalization, improved credit support for strategic sectors of the economy (for example, shipbuilding can be achieved through the creation of a banking consortium based around leasing. A dialectical method of resolution of system tasks is selected as the methodological approach. Methods used include: comparative cost analysis of the strategic lending industry supporting the formation and development of a banking consortium; integrated method at the condition modeling of making and implementation of a lease agreement, which allowed to accommodate the interests for both parties of such agreement; optimization method to select the conditions of a lease agreement; classification and analytical method to clarify the classification of lease. The study proved and developed a plan of creation a banking consortium, including options of interaction of such consortium with potential customers based on a lease agreement. The process of functioning of the lease agreement in order to optimize it for both a bank consortium-lessor and a lessee is modeled. The significant advantages of leasing compared to the traditional lending for both parties of leasing, especially when ensuring long-term projects are summarized. The results of the research can be applied in the strategic lending industries development and can reduce the level of banking risks. Applying the results of the research in the social aspect can maintain and increase the number of jobs including the banking sector. The value of the work leis in the fact that the author has developed a new approach to achive the credit support for strategic sectors of the economy through the creation of the banking consortium based around leasing, which allows to protect the interests of both parties.

Product archaeology as an educational approach asks engineering students to consider and explore the broader societal and global impacts of a product's manufacturing, distribution, use, and disposal on people, economics, and the environment. This study examined the impact of product archaeology in a project-based engineering design course on student attitudes and perceptions about engineering and abilities to extend and refine knowledge about broader contexts. Two design scenarios were created: one related to dental hygiene and one related to vaccination delivery. Design scenarios were used to (1) assess knowledge of broader contexts, and (2) test variability of student responses across different contextual situations. Results from pre- to post-surveying revealed improved student perceptions of knowledge of broader contexts. Significant differences were observed between the two design scenarios. The findings support the assumption that different design scenarios elicit consideration of different contexts and design scenarios can be constructed to target specific contextual considerations.

This study aims to determine the floristic characteristics of alien invasive seed plant species (AISPS) in China. There are a total of five hundred and thirteen AISPS, belonging to seventy families and two hundred and eighty-three genera. Seventy families were classified into nine areal types at the family level, and "Cosmopolitan" and "Pantropic" are the two main types. Two hundred and eighty-three genera were classified into twelve areal types at the genus level, and "Pantropic", "Trop. Asia & Amer. disjuncted", and "Cosmopolitan" are the three main types. These results reveal a certain degree of diversity among AISPS in China. The floristic characteristics at the family level exhibit strong pantropic characteristics. Two possible reasons for this are as follows. Firstly, southeastern China is heavily invaded by alien invasive plant species and this region has a mild climate. Secondly, southeastern China is more disturbed by human activities than other regions in China. The floristic characteristics at the genus level display strong pantropic but with abundant temperate characteristics. This may be due to that China across five climatic zones and the ecosystems in which the most alien invasive plant species occur have the same or similar climate with their natural habitat.

Full Text Available LE RECUL DES GLACIERS DU MONT KENYA DANS LE CONTEXTE GLOBAL DES TROPIQUES. Les glaciers ont commencé leur retrait autour de la moitié du XIXème siècle dans les Andes équatoriales et en Nouvelle-Guinée, mais il faut attendre la fin du XIXème siècle pour les voir entamer leur recul en Afrique de lEst. Dans cette région, la déglaciation, comme la baisse du niveau des lacs, est due à des changements hydroclimatiques survenant à la suite de modifications de la circulation atmosphérique dans lOcéan Indien. La diminution des surfaces englacées est attribuée à une réduction de la nébulosité accompagnée dune baisse des précipitations. Par la suite, un réchauffement progressif et une augmentation de lhumidité atmosphérique sont devenus les facteurs dominants. La déglaciation tend à saccentuer sous tous les Tropiques depuis deux décennies. RETROCESO DE LOS GLACIARES DEL MONTE KENYA EN EL CONTEXTO GLOBAL DE LOS TRÓPICOS. El retroceso de los glaciares empezó, en los Andes del Ecuador y en Nueva Guinea, a mediados del siglo XIX más o menos, y sólo a fines de este siglo en África del Este. En esta zona, tanto el principio del retroceso de los glaciares como el descenso del nivel de los lagos, han sido provocados por un cambio de las condiciones hidroclimáticas debido a cambios en el sector del Océano Índico. Una reducción de la nubosidad acompañada por una disminución de las precipitaciones tuvo el rol más importante en el proceso de desglaciación. Después, el progresivo recalentamiento y el aumento de la humedad atmosférica fueron los factores dominantes. La desglaciación es un fenómeno que se acentuó en todo el Trópico durante los dos últimos decenios.

This research note shares insights which resulted from a larger study into the ways in which the United Nations Educational, Scientific and Cultural Organization (UNESCO) - during 2010-2014 - used its position as coordinator of the post-Dakar Framework for Action (initiated at the World Education Forum held in 2000 and designed to reinvigorate the Education for All initiative) to help it regain some of the legitimacy it had lost in the preceding decades. The research study focused on the role of both the UNESCO Education for All Follow-up Unit and the production of the Global Monitoring Report (GMR) during the 2000s because they were at the heart of UNESCO's efforts to repair its image and renew its impact in one area of global governance, specifically in the global education policy field. The study's findings were based on an analysis of documents, archives and interviews ( n = 17) with key actors inside and outside UNESCO, including representatives of UNESCO's peer institutions.

The habitat type *9562 Grecian juniper woods (Juniperetum excelsae) includes Greek juniper (Juniperus excelsa M. Bieb.) forests and they are found mainly in the western sector of the Prespa National Park, NW Greece. Greek juniper forests are considered extremely rare for EU-28, recommending a priority habitat type in accordance with Directive 92/43/EEC. In addition, their ecological importance is great given its high plant taxa richness; they harbor most of the 900 plant taxa found in the western sector of the Park, many of them being important for EU or global scale. The accelerated invasion of deciduous hardwoods is the most significant risk for the habitat, since its rich flora is well-adapted to open light conditions produced by the open spaced Greek junipers. Also, the dense vegetated conditions deprive the regeneration of the photophilous Greek juniper. The invasion results from the lack of its natural controller, i.e. the grazing livestock. It is estimated that the total area of juniper forests for the Devas area decreased to 89% of the area of 1945 in favor of invasive hardwoods. The paper presents the analysis of the floristic diversity of the priority habitat type *9562 Grecian Juniper Woods (Juniperetum excelsae) (GJWs). Four (4) types of juniper forest ranges (GJWs) were distinguished in terms of canopy cover: (a) pure GJWs, (b) mixed open GJWs, (c) open GJWs, and (d) mixed dense GJWs. A total of 171 plant taxa were recorded, and distributed within 43 botanical families; the largest one being Leguminosae (26 taxa). The statistically estimated plant taxa richness for pure GJWs was 116.4, for mixed open 152.6, for open 57.9, and for mixed dense 90.2 taxa. The analysis of α-diversity indices did not reveal any specific trend of diversity for the four GJWs. The behavior of the variability of diversity among the four range types of GJWs was depending on the emphasis the used indices place on properties such as taxa richness or abundance. This fact was

Full Text Available With the development of globalization waves, the cross-cultural communication becomes more and more common nowadays. Chinese films, as a kind of mass media and the carrier of ideology, must meet the challenge in the world with active attitudes and take part in cross-cultural communication worldwide extensively. The context of globalization is not only a challenge but also an opportunity for Chinese films and if Chinese films want to be successful in the process of cross-cultural communication, it must find out a conjoint point between globalization and location to implement dual-coding of them. With the objective of consensus but different for the cultural demands of cross-cultural communication, the communicational strategies in culture，subject，art and operation must extensively use for reference and boldly create to renew the situation of Chinese films．

Full Text Available As a result of globalization process the world becomes more and more integrated, the role of “hard” power becomes lower, while the role of “soft” power, vice versa, increases. Sport as one of the most important spheres of human activities, faces both positive and negative effects of globalization. Sport has an important function in the concept of “soft” security, and this importance is evidenced by serious attention, paid by the United Nations and other international organizations. The UN established the International Day of port, and it organizes regular meetings and conferences devoted to sport. Plenty of the UN Organizations officially use sport to achieve their aims. Sports diplomacy is believed to have reconciling, uniting role; sport must contribute to resolution of the most part of contemporary global problems. Abilities of the Information age allow using positive effect caused by sport events with maximal benefits. There is understanding in the UN, that sport alone cannot solve all global problems, but it can relieve their consequences. Therefore sport is used to struggle over such problems, as poverty; peace and security problems; disarmament necessity; human rights and democracy problems; demography, ecology and energy problems, difficulties with medical care and provision. On the other hand, sport suffers from globalization; it loses its initial function of competition due to politicization and commercialization. Even new issues of confrontation appear because of sports. Only global governance over sport, establishment of general rules and clear goals and their joint accomplishment can allow the international sports movement become a real force in fight against global problems.

Global temperature decline associated with the Eocene-Oligocene transition resulted in extinctions of plants and animals in both marine and nonmarine environments. The extensive stratigraphic exposures, well-preserved palynological assemblages, and interbedded coal seams of the nonmarine Amphitheatre Formation, Burwash Basin, Yukon Territory, provide a comprehensive record of this transition. The formation spans a paleoclimatically significant interval otherwise poorly represented in high-latitude deposits of the northwestern Cordiller. Palynological data constrained by the chronologic and stratigraphic framework established for the Amphitheatre Formation indicate that the global temperature decline resulted in a shift from warm temperate, angiosperm-dominated to cooler temperate, gymnosperm-dominated (mainly coniferous) forest types. Petrographic compositional changes in the coals document the same plant community changes. The floristic data also indicate that, at high latitudes, there may have been a change to a wetter and less seasonal climate during the overall global cooling trend.

Full Text Available This paper investigates the international business literature of the last forty years from the incorporation of the term global cities as a reference in the construction of new theoretical contributions. A bibliometric method was performed in two stages. In the first one, the main areas of knowledge and the seminal studies addressing the concept were identified. Most research focuses on economic geography and urban studies. In the second, the approaches used specifically in international business were organized in the main journals of the area. The results show that the studies on global cities are still incipient, highlighting, among the approaches, the relation between location advantages and specific aspects of the multinational company. In addition, there is a growing interest in the development of analyzes at the subnational level represented by global cities, from different aspects such as the choice of entry mode, the role of advanced service firms, the importance of networks and the process of knowledge transfer. The combination of the perspectives of economic geography and international business, although claimed by scholars from both areas, still lacks a more robust theoretical and empirical body in regard to cities as centers of attractiveness of foreign investment in global markets. In analyzing the importance of the phenomenon of global cities, this study contributes to a better understanding of the contemporary internationalization strategies of multinational companies, highlighting the interdisciplinary potential between international business theories and economic geography.

Full Text Available The transnational ex-gay movement is an important context affecting lesbians and sexual minority women around the world. In 2015, the UN Human Rights Commissioner called for all nations to ban conversion therapies. This research investigates a neglected area of scholarship on the ex-gay movement by deconstructing and analyzing the implications of ex-gay discourses of female homosexuality in a global context. The ex-gay movement originated in the United States and has proliferated to nearly every continent. We argue that it is the main purveyor of public, anti-lesbian rhetoric today, constructing lesbianism as sinful and sick to control women’s sexuality, enforce rigid gender roles and inequality, and oppress sexual minority women. Guided by Adrienne Rich’s theory of compulsory heterosexuality and Barbara Risman’s gender structure theory, we analyze how, in ex-gay discourse, lesbianism is demeaned and demonized in the individual, interactional, and institutional dimensions of the gender structure. Finally, we examine the impact of ex-gay discourse on sexual minority women in global context.

Full Text Available Within the context of multi-cultural and multi-religious society, embedded in the process of globalization, a traditional understanding of humanism offers insufficient frameworks for an adequate comprehension of human flourishing and human search for meaning. In addition, modernity frames and evaluates in many aspects insufficiently the incomparable worth of the human person. This article offers some guidelines for further philosophical, theological and pedagogical reflection on a humanism that is more suitable for our life in the process of globalization and modernity. Such humanism continually moves us toward a better comprehension of what “human” means within a universe of divergent cultures, religions, traditions, and races. This humanism is called universal humanism , based on the Greek word kaqolou , comprising both universality and wholeness. The first part of this article analyzes some of the main characteristics of humanism in the Greek and Roman contexts, which provide historical and theoretical frameworks for universal humanism. The second part justifies the relevance and usefulness of such humanism: it helps us to transcend singular cultures, nations, political systems, religions, and, by default, to discover or explore anew the meaning of the human person on a global level. The last part of this article suggests some pedagogical attitudes that will help us to embrace and remain in a dialogical relationship with all of humanity, in order to enrich our comprehension of the incomparable worth of the human person, this time from a universal perspective.

An increasing amount of health policy is formulated at global level. At this global level, palliative care has attracted support primarily from normative institutions (WHO), not funding agencies. To attract greater global attention from policymakers, it has been argued that an international approach to research is required. However, the extent to which an international approach is being undertaken is unknown. To systematically identify and thematically synthesise all international palliative care research, defined as research involving two or more countries, or focused on the global level. Five bibliographic databases (CINAHL, Cochrane Library, ASSIA, Web of Knowledge, Psychinfo) were searched for journal articles relevant to international and global palliative care and end-of-life care. Data were extracted using a piloted extraction form and findings were synthesised. 184 studies were included, published across 75 different academic journals. Research emanates from and focuses on all world regions and there is increasing focus on the global level. Thematically, there is a high focus on Evaluation (n=53) and views of Stakeholders (n=38). The review revealed a predominantly observational research approach and few interventional studies were identified. International palliative care research is a relatively new, but growing field. However, many gaps in the evidence base remain and palliative care research continues to take place outside broader discourses of international development. The relative absence of interventional research demonstrating the effectiveness and cost-effectiveness of palliative care risks limiting the tools with which advocates can engage with international policymakers on this topic.

Accountability in global health is a commonly invoked though less commonly questioned concept. Critically reflecting on the concept and how it is put into practice, this paper focuses on the who, what, how, and where of accountability, mapping its defining features and considering them with respect to real-world circumstances. Changing dynamics in global health cooperation - such as the emergence of new health public-private partnerships and the formal inclusion of non-state actors in policy making processes - provides the backdrop to this discussion. Accountability is frequently reduced to one set of actors holding another to account. Changes in the global health landscape and in relations between actors have however made the practice of accountability more complex and contested. Currently undergoing a reframing process, participation and transparency have become core elements of a new accountability agenda alongside evaluation and redress or enforcement mechanisms. However, while accountability is about holding actors responsible for their actions, the mechanisms through which this might be done vary substantially and are far from politically neutral.Accountability in global health cooperation involves multipolar relationships between a large number of stakeholders with varying degrees of power and influence, where not all interests are realised in that relationship. Moreover, accountability differs across finance, programme and governance subfields, where each has its own set of policy processes, institutional structures, accountability relations and power asymmetries to contend with. With reference to the Global Fund to Fight HIV/AIDS, Tuberculosis and Malaria, this paper contributes to discussions on accountability by mapping out key elements of the concept and how it is put into practice, where different types of accountability battle for recognition and legitimacy. In mapping some defining features, accountability in global health cooperation is shown to be

The Earth's seven billion humans are consuming a growing proportion of the world's ecosystem products and services. Human activity has also wrought changes that rival the scale of many natural geologic processes, e.g. erosion, transport and deposition, leading to recognition of a new geological epoch, the Anthropocene. Because of these impacts, several natural systems have been pushed beyond the planetary boundaries that made the Holocene favorable for the expansion of humanity. Given these human-induced stresses on natural systems, global citizens will face an increasing number of grand challenges. Unfortunately, traditional discipline-based introductory science courses do little to prepare students for these complex, scientifically-based and technologically-centered challenges. With NSF funding, an introductory, integrated science course stressing quantitative reasoning and social context has been created at UW. The course (GEOL1600: Global Sustainability: Managing the Earth's Resources) is a lower division course designed around the energy-water-climate (EWC) nexus and integrating biology, chemistry, Earth science and physics. It melds lectures, lecture activities, reading questionnaires and labs to create a learning environment that examines the EWT nexus from a global through regional context. The focus on the EWC nexus, while important socially and intended to motivate students, also provides a coherent framework for identifying which disciplinary scientific principles and concepts to include in the course: photosynthesis and deep time (fossil fuels), biogeochemical cycles (climate), chemical reactions (combustion), electromagnetic radiation (solar power), nuclear physics (nuclear power), phase changes and diagrams (water and climate), etc. Lecture activities are used to give students the practice they need to make quantitative skills routine and automatic.

Despite ample research demonstrating the role of motivation and self-efficacy in predicting drinking in the context of abstinence, little research explicitly explores their role in the context of moderation, and none have utilized daily diary methods. The purpose of this study was to (a) explore the concordance between global self-report and daily diary composite measures of motivation and self-efficacy and (b) compare the ability of each in predicting drinking outcomes in the context of a study of brief AUD treatments focused on controlled drinking. Problem drinkers (N = 89) were assessed, provided feedback about their drinking, and randomly assigned to one of three conditions: two brief AUD treatments or a third group asked to change on their own. Global self-report (GSR) measures were administered at baseline and Week 8 (end of treatment). Daily diary composites (DDC) were created from data collected via an Interactive Voice Recording system during the week prior to baseline and the week prior to Week 8. Findings revealed some concordance between GSR and DDC at both baseline and Week 8, indicating the two methods capture some of the same construct; however, their respective relationships to drinking differed. DDC for both baseline and Week 8 significantly predicted Week 8 drinking outcomes, whereas only change in GSR significantly predicted drinking outcomes. Findings suggest that motivation and self-efficacy are important to moderated drinking, and that both GSR and daily diary methods are useful in understanding mechanisms of change in the context of moderation. Daily diary methods may provide significant advantages. Limitations and arenas for future research are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

The study of how long-term changes affect metacommunities is a relevant topic, that involves the evaluation of connections among biological assemblages across different spatio-temporal scales, in order to fully understand links between global changes and macroevolutionary patterns. We applied multivariate statistical analyses and diversity tests using a large data matrix of rodent fossil sites in order to analyse long-term faunal changes. Late Miocene rodent faunas from southwestern Europe were classified into metacommunities, presumably sharing ecological affinities, which followed temporal and environmental non-random assembly and disassembly patterns. Metacommunity dynamics of these faunas were driven by environmental changes associated with temperature variability, but there was also some influence from the aridity shifts described for this region during the late Miocene. Additionally, while variations in the structure of rodent assemblages were directly influenced by global climatic changes in the southern province, the northern sites showed a pattern of climatic influence mediated by diversity-dependent processes.

The author identifies three models of national criminal policy: the sovereign, reformist and experimental. The main criteria of such differentiation are the exposure to global influence, the criminological soundness and stability of criminal policy. The sovereign model is based on doctrine of weak state and a strong combat criminal activity. It is distinguished by the pursuit of the realization of the equality of all before the law, criminal strategic and political planning system with a clear definition of goals and objectives; criminological security. The reform of criminal policy is characterized byuncertainty goals and objectives, utopianism and pretentiousness, dependence on standards of the international organization, the lower prestige of criminology, reduction of social programs, lobbying of group interests, permanent amendments to the criminal and criminal procedure legislation. Experimental model of criminal policy is connected with approbation of such technologies of management of society that are criminal and contrary to human experience in fighting crime.Conclusions.

Full Text Available This paper draws upon findings from a research study on the relationship between fiction, citizenship, and lifelong learning. It includes interviews with authors from several genres, publishing houses, and arts councils. This paper explores many of the ambivalent outcomes of the shifting power elements in publishing that can simultaneously benefit and disadvantage the publication of a national body of fiction. Although focused on the Canadian context, fiction writers and publishers around the globe face similar challenges. Using a Foucauldian analysis, it considers the importance of fiction and adult learning in shaping discourses of citizenship and critical social learning.
Full Text Available The work studies interreligious relations and constructive dialogue between Christians and Moslems in a context of world crisis as a crisis of modernity whic epicenter is placed within western civilization. Having noticed motives of manipulative 'crisis menagement', as creating, amplifying, escalating, control and pacification of an interreligious conflict as a certain 'conflict of civilizations' by postmodern, neocolonial imperialism, the author focuses on manipulation with religious feelings in the case of Bosnian war, by the end of the 20th century. Having without doubt determined that the conflict was a political one and only sporadically a religious-civilisational one with considerable influence of neoimperial interfering using the rule 'divide and rule', it furthermore analises interetnical and interreligious relations between Christians and Moslems in Bosnia and Balcans at the beginning of the 21st century. Having noticed the growth of religionness in the whole area, and the growth of mutual confidence and a perspective that opens constructive dialgue, the work makes conclusion of being possible to gain consensus based on a 'smallest common traditional denominator', where religious and cultural identities would becama a base of cooperation and approach, and not a conflict, and of possibility of building a social alternative to neocolonial order that rules this area on these bases, in a context of the crisis of modern West.

Full Text Available Impacts of global climate change, habitat loss, and other environmental changes on the world's biota and peoples continue to increase, especially on islands and in high elevation areas. Just as floristic diversity is affected by environmental change, so too are cultural and linguistic diversity. Of the approximately 7000 extant languages in the world, fully 50% are considered to be at risk of extinction, which is considerably higher than most estimates of extinction risks to plants and animals. To maintain the integrity of plant life, it is not enough for botanic gardens to consider solely the effects of environmental change on plants within the context of major conservation strategies such as the Global Strategy for Plant Conservation and the Convention on Biological Diversity. Rather, botanic gardens should actively engage in understanding and communicating the broader impacts of environmental change to biological and cultural diversity.

Cold supply systems are directly related to solving the problems of food supply security of the country. Artificial refrigerationhas a key role in supplyingand preserving food for the population. According to the International Institute of Refrigeration (IIR, artificial refrigeration plays an important role in the social, economic, and environmental spheres. The Concept of long-term development of refrigeration engineering with the purposeof energy saving and environmental protection sets the problem of reducing energy consumption by 30-50% decreasing refrigerant leaks twice. In 2015 the proportion of refrigeration equipment supplied by import or collected in Russia from imported components ranged from 40 to 60%. Russia's entry to the World Trade Organization (WTO, contributing to the globalization of the world economy, has given a rise to the development of the refrigeration industry. Reduction of customs duties on imported equipment led to the development of Russian companies andprice cut of home equipment.The level of service maintenance of home equipmentalso has increased due to international cooperation. However, there are some drawbacks. Nowadaysall factories of refrigeration engineering in Russia mustuse their own patented technologies or pay for the use of technologies patented in other countries.There are more stringent requirements in observanceof international agreements on environmental protection ,limiton the production and use of halogenated hydrocarbons as refrigerants and refrigeration equipment, which requires additional investment for refrigeration systems and their production. It should be noted that with the development of globalization of world economies, the protection of the interests of home refrigeration engineering in order to ensure economic security is becoming extremely important.

Full Text Available European countries have taken part in the Globalization process ever since the end of the Second World War. Being active members of international institutions like the IMF, World Bank Group, NATO or the WTO, the European countries have even developed a collective entity of their own, that of the European Union. In later years, Eastern European countries like Romania have also become a part of this globalised system. It is the aim of this paper to present the effects that this integration has brought in terms of economic development and security challenges for EU member states, by taking into consideration the example of Romania.

Full Text Available The article is aimed at defining the conceptual-strategic principles of ensuring the international competitiveness of tourism enterprise. As result of research the essence and value of management of competitiveness of tourism enterprise in the conditions of globalization were considered. Factors of formation of competitive advantages, and also the reasons determining competitiveness of a tourism product have been determined. The main aspects of formation of quality of services provision have been identified. On the basis of the carried out research, the concept of integrated marketing communications has been formed, which is a combination of traditional ways of communication activity with the only synchronized communication, oriented towards establishing the multichannel relationships with different target audiences, with choosing an own marketing model for each audience. Application of the given concept would allow to optimally choose means of communication and to provide more effective realization of a tourism product at the international market of tourism services that will promote companies’ overgrowing their local status and gaining their self-importance on a global scale.

A new international initiative for plant conservation was first called for as a resolution of the International Botanical Congress in 1999. The natural home for such an initiative was considered to be the Convention on Biological Diversity (CBD), and the Conference of the Parties (COP) to the CBD agreed to consider a Global Strategy for Plant Conservation (GSPC) at its 5th meeting in 2000. It was proposed that the GSPC could provide an innovative model approach for target setting within the CBD and, prior to COP5, a series of inter-sessional papers on proposed targets and their justification were developed by plant conservation experts. Key factors that ensured the adoption of the GSPC by the CBD in 2002 included: (1) ensuring that prior to and during COP5, key Parties in each region were supportive of the Strategy; (2) setting targets at the global level and not attempting to impose these nationally; and (3) the offer by Botanic Gardens Conservation International (BGCI) to support a GSPC position in the CBD Secretariat for 3 years, which provided a clear indication of the support for the GSPC from non-governmental organizations (NGO).
Full Text Available The Romanian companies are nowadays facing process of extinction of decisions based on risk and uncertainty, as a consequence of the permanent transforming process of the economy and because of the privatization, restructuring and globalization activities. The main forms of risk are can be grouped in eight categories: economical risks, financial risks, commercial risks, manufacturing risks, political risks, social risks, juridical risks, natural risks. Through its nature the decision is referring to the future, mainly being provisional. In any decisional process developed at the company level, there are involved in the same time some economical, techniques, juridical, human and managerial variables. The economic recession generated by the chaos affecting financial systems has profoundly distressed the public, business circles and political leaders. The crisis has inexorably had negative effects on global economic growth and will have political, strategic and social consequences as well. The contents of this paper encompasses theoretical and practical aspects, quantitative and qualitative analyses, all aimed at identifying, analysing and controlling bank risks and, last but not least, at managing these risks.
Full Text Available Globalization is a reality that we cannot deny or run away from. The economic, political or social issues, even if they have a starting point, spread very quickly, covering large areas in a very short time. Modern communication systems enable crisis transfer. They also bring us information about the actions that have been taken in order to overcome those critical circumstances. Does recession have positive aspects, too? If it has, what are these positive aspects and how can they be used to produce highest benefits? We will try to describe the concepts we maintain by means of some notorious works written by authors with a vast experience, some of them being Noble Prize winners. The idea that we propose is to bring hope out of this situation generated by crisis and globalization. The economic crisis has created a huge opportunity to the mass-media system: it brings the required information to citizens from different nations. Taking this into account, mass-media has played and still plays an important part in making the people involved find solutions and communicate whenever the decision makers are trying to hide facts. With the help of innovation and transformation, letâ€™s look for solutions to develop our abilities, relationships, products, markets and results. We should never forget that the greatest and most impressive changes are often born in times of crisis.
Full Text Available The objective of this paper is to examine Romania’s capacity to fulfil the nominal convergence criteria in the current context, in order to follow the calendar proposed for euro adoption in 2015. The paper analyzed the evolution of all five criteria under the impact of the current financial crisis and also looked at the forecast provided by national and international authorities. The study was conducted considering the relative situation with the euro area. The main finding is that the actual target for euro adoption could be complied with, provided further progress is made. We have also fond that the target should be achieved as it would represent a strong stimulus for the local government to implement additional measures to reduce public indebtedness and inflationary pressure.

Full Text Available This paper presents some outside views on the emergence of Chinese constitutional thought. It shows that Chinese constitutionalism in the beginning of the 20th century did matter to the outside world and did attract a large interest on a global scale. Foreign views were quite diverse. While most observers welcomed the adoption of a constitution in principle, there were many words of caution that such a transition should not be rushed, notedly among diplomats and politicians. Foreign powers thus adopted a policy of not pressuring China to adopt a constitution. In particular, this paper redefines the role of the Japanese statesman Itô Hirobumi, who continually tried to give his advice to the Qing government up until his death in 1909.

The global warming effect due to ?greenhouse gases? is a hot topic discussed by world climate scientists today. This effect causes sea levels to rise, countries experiencing extreme weather conditions, violent storms and long dry spells. In centuries to come, these catastrophic effects can cause the spread of diseases and destroy food production and human habitat. Over one-third of the greenhouse gases come from the burning of fossil fuel to generate electricity. Nuclear power plants do not generate these gases. This paper presents the results obtained from a case study using MESSAGE, an analytical tool developed by the IAEA, which was used to evaluate Malaysia future energy requirements and strategies in addressing climate change issues.

Full Text Available Abstract The University is tasked with drawing together, transmitting and maintaining knowledge, while creating an area where the ethical "sense" required for working in the field of Biology and Biomedicine can be provided. Although scientific knowledge is present on an overwhelming scale in nature and, therefore, its discovery is unceasing, this does not mean that, as a human being, the researcher has no limitations. It is Bioethics that sets this limit. The successful spreading of knowledge, therefore, which is proclaimed with the creation of a Global Higher Education Area, should also pursue the establishment of the bioethical principles necessary for the credibility of science and its progress so that the society that it promotes and sustains becomes a reality.

Though coal remains the main fuel for power generation worldwide, concerns regarding the contribution of coal-fired power generation to global warming have also increased considerably in recent years. These concerns have somewhat eclipsed the many advantages of the use of coal for power generation. The attitudes of the public towards power generation from a particular fuel is an important factor in shaping government policy. For example, such attitudes are crucial in determining whether new coal-fired projects can proceed. This report describes current public attitudes towards coal-fired power plant in several countries both in the developed and developing world. It compares these attitudes with those reported in an earlier report on this subject produced in 2006. Since then, the publication of the IPCC report in 2007 and the greater worldwide consensus on the reality of global warming following the change in administrations in the USA and Australia would be expected to affect public attitudes. However, events in late 2009 have increased the levels of public scepticism. The report principally collates opinion poll data available on the public's attitude towards energy, environment and the use of coal for power generation. Whereas before 2006, surveys of attitudes towards energy sources commonly included coal-fired plant, more recently coal plant are rarely included, presumably as it is assumed that the public would be overwhelmingly opposed. Hence the subject has been broadened to include attitudes to climate changeand CCS. It also reports what national and international organisations say about the use of coal. It investigates what the general public and concerned organisations say should be done to reduce the greenhouse effect. Countries and regions chosen for particular focus are the USA, the European Union, the UK, India, Thailand and Australia. 121 refs., 38 figs., 26 tabs.
Full Text Available Human rights and democracy have been regarded as a mutually reinforcing couple by many political theorists to date. The internationalisation of human rights post-1945 is often said to have severed those links, however. Accounting for the legitimacy of international human rights requires exploring how human rights and democracy, once they have been decoupled or disconnected, can be recoupled or reunited across governance levels (vertically and maybe even at the same governance level (horizontally albeit beyond the state. The article does so in three steps. The first prong of the argument is dedicated to presenting the moral-political nature of human rights and their relationship to political equality and, hence, their inherent legal nature from a democratic theory perspective. The second section of the article then draws some implications for the domestic or international levels of legal recognition and specification of human rights by reference to their legitimation within the domestic democratic community. It explains the mutual relationship between human rights and citizens’ rights and where international human rights draw their democratic legitimacy from. In the third and final section, the author discusses potential changes in the nature and legitimacy of international human rights once political structures beyond the state become more democratic, and human rights and democracy are being recoupled again at various levels of governance. The European Union being one of the most advanced examples of post-national political integration, recent developments in the regime of human rights protection within the EU are discussed in this new light. In a final step, the transposition to the global level of the argument developed in the European case is assessed and the author flags issues for further research on what democratic theorists should hope for in the new global order.

The spread of evidence-based practice throughout the world has resulted in the wide adoption of empirically supported interventions (ESIs) and a growing number of controlled trials of imported and culturally adapted ESIs. This article is informed by outcome research on family-based interventions including programs listed in the American Blueprints Model and Promising Programs. Evidence from these controlled trials is mixed and, because it is comprised of both successful and unsuccessful replications of ESIs, it provides clues for the translation of promising programs in the future. At least four explanations appear plausible for the mixed results in replication trials. One has to do with methodological differences across trials. A second deals with ambiguities in the cultural adaptation process. A third explanation is that ESIs in failed replications have not been adequately implemented. A fourth source of variation derives from unanticipated contextual influences that might affect the effects of ESIs when transported to other cultures and countries. This article describes a model that allows for the differential examination of adaptations of interventions in new cultural contexts. © The Author(s) 2012.

Full Text Available A set of recent international studies reveal the scarcity of coherent entity-level estimation systems able to lead to an adequate identification and valuation of social and environmental performance, despite the large number of entities claiming their concern for the environmental impact of their business activities.The status quo is mainly caused by the lack of domain-specific accounting regulation, along with a general "information gap" in the field of the potential benefits eco-costs and externalities absorption may generate. Eco-costs and externalities absorption technologies for the costing model are still going through their experimental stages, aiming to reflect both the historicalpolitical context and the philosophical motivations of an organization's management and stakeholders. We held as appropriate (and the paper at hand will speak for the intent to promote this class of technologies for the Romanianbusiness environment, mainly by reviewing the relevant literature in the field and developing an eco-costing model able to provide cost levels consistent with the sustainable development goals.

Full Text Available Berdasarkan kajian terhadap sejarah kemunculan dan sistem operasional Bank Islam beserta kinerjanya, penulis menyimpulkan bahwa konsep bank Islam pada hakekatnya merupakan bentuk islamisasi terhadap institusi perbankan. Hanya saja proses islamisasi yang terjadi baru sebatas pada aspek-aspek yang bersifat marginal, artifisial, dan formal-institusional, seperti penggantian istilah-istilah teknis dalam dunia perbankan dengan istilah yang berasal dari fikih muamalah, penghapusan bunga, dan penolakan terhadap praktek-praktek bisnis yang haram. Selebihnya, bank Islam tidak berbeda dengan bank konvensional. Dampak dari islamisasi yang kurang substansial-komprehensif tersebut adalah timbulnya kesan bahwa bank Islam justru ‘terbelenggu’ oleh konsep-konsep fikih klasik yang mendasarinya, di mana ia cenderung kontra produktif dengan tren bisnis moderen yang senantiasa menuntut efisiensi dan fleksibilitas. Agar tetap dapat survive di masa-masa mendatang, bank Islam perlu mengevaluasi diri secara terus menerus dengan selalu membuka diri terhadap berbagai kritikan yang dialamatkan kepadanya. Konsepsi yang terlalu berorientasi kepada doktrin harus diimbangi dengan kesadaran akan fakta-fakta dan tuntutan bisnis moderen, baik yang berskala lokal maupun global. Sementara itu cita-cita Islam yang ideal, seperti pemberantasan kemiskinan, pendistribusian kekayaan secara adil, dan penciptaan lapangan kerja, harus tetap menjadi orientasi utamanya. Kata Kunci:Riba, Profit and Loss Sharing, Mudlârabah, Murâbahah, Artificial Aspects of Islam Abstract:Based on the study of the history of emergence and operation of Islamic Bank and its system performance, the author conclude that the concept of Islamic bank is essentially a form of Islamization of the banking institutions. Such Islamization are limited to the marginal, artificial, and formal-institutional aspects, such as the replacement of technical terms in the banking world with a term derived from the fiqh
Full Text Available Purpose: As part of a national research survey into the importance and implementation of six managerial competencies, this article aims to investigate the importance a national sample of reporters and first-line newsroom managers in South Africa's mainstream media attach to global awareness as a managerial competency. It also aims to establish gaps between the importance attached to and current implementation thereof by the latter. Design/Methodology/Approach: Qualitative and quantitative research designs were combined to obtain the most comprehensive view on the research problem. Quantitative data was compiled through self-administered questionnaires among first-line newsroom managers and reporters employed by the country's mainstream media. Qualitative data was obtained through semi-structured interviews and observational research. These sets of data were combined triangularly to improve validity and reliability. Quantitative data was analysed through factor analysis and effect size analysis, while qualitative data was analysed through qualitative content analysis. Findings: It was found that both respondent groups perceive first-line newsroom managers unable to implement the skills associated with the global awareness competency (given the importance they attach to it. While in some cases first-line newsroom managers themselves were more aware of their shortcomings, reporters highlighted other instances where they perceive their superiors unable to perform as expected. Implications: Given the challenges associated with globalisation, media managers need skills to identify and realise the impact of national and international changes on their business activities. South African media managers must also identify and address the challenges associated with the multilingual and multicultural backgrounds of their newsroom staff. Originality/Value: The dimensions of global awareness as a managerial competency are rooted in general management theory

We analyzed floristic variations in fern's metacommunity at the local scale and their relationship with abiotic factors in an Atlantic Forest remnant of northeastern Brazil. Floristic and environmental variations were accessed on ten plots of 10 × 20 m. We performed cluster analyses, based on Bray-Curtis dissimilarity index to establish the floristic relationship. The influence of abiotic factors: luminosity, temperature, relative air humidity and relative soil moisture was evaluated from a redundancy analysis. We found 24 species belonging to 20 genera and 12 families. The fern's flora showed high floristic heterogeneity (>75% for most of the plot's associations). The fern's metacommunity was structured along an abiotic gradient modulated by temperature, luminosity, and relative soil moisture.

Full Text Available Riparian forest has a key ecological and economic significance to productive chains associated with it. This study aimed to conduct a floristic survey of riparian forest stretches in the Gramame river, state of Paraíba, Brazilian Northeast region, and analyze the floristic similarity with Brazilian riparian vegetation fragments. We found 136 species belonging to 106 genera and 43 families. The most representative families were: Fabaceae (19 spp., Cyperaceae (16 spp., and Rubiaceae (11 spp.. The predominant habit was herbaceous and the best represented biological spectrum was camephyte. Regarding the geographic distribution, there was a predominance of widely distributed species associated with the Neotropical province. The distribution patterns have shown a low similarity between areas, and largely distributed species stand out. Similarity analysis pointed out that the area was floristically related to other two coastal areas in the Brazilian Northeast and Southeast regions. Only species typically related to estuarine environments might explain the floristic connections detected.

We assessed the quality of plant communities across a range of lead (Pb) and zinc (Zn) soil concentrations at a variety of sites associated with Pb mining in southeast Missouri, USA. In a novel application, two standard floristic quality measures, Mean Coefficient of Conservatism (Mean C) and Floristic Quality Index (FQI), were examined in relation to concentrations of Pb and Zn, soil nutrients, and other soil characteristics. Nonmetric Multidimensional Scaling and Regression Tree Analyses identified soil Pb and Zn concentrations as primary explanatory variables for plant community composition and indicated negative relationships between soil metals concentrations and both Mean C and FQI. Univariate regression also demonstrated significant negative relationships between metals concentrations and floristic quality. The negative effects of metals in native soils with otherwise relatively undisturbed conditions indicate that elevated soil metals concentrations adversely affect native floristic quality where no other human disturbance is evident.

Prediction of Indian summer monsoon rainfall (ISMR) is at the heart of tropical climate prediction. Despite enormous progress having been made in predicting ISMR since 1886, the operational forecasts during recent decades (1989–2012) have little skill. Here we show, with both dynamical and physical–empirical models, that this recent failure is largely due to the models' inability to capture new predictability sources emerging during recent global warming, that is, the development of the central-Pacific El Nino-Southern Oscillation (CP–ENSO), the rapid deepening of the Asian Low and the strengthening of North and South Pacific Highs during boreal spring. A physical–empirical model that captures these new predictors can produce an independent forecast skill of 0.51 for 1989–2012 and a 92-year retrospective forecast skill of 0.64 for 1921–2012. The recent low skills of the dynamical models are attributed to deficiencies in capturing the developing CP–ENSO and anomalous Asian Low. The results reveal a considerable gap between ISMR prediction skill and predictability. PMID:25981180
Energy is the driving force towards economic and social development. Global demand for energy will keep growing for many years to come due to ongoing, although reduced population growth, and due to the needs of up to 2 billion people who are still without access to commercial energy. To meet this growing demand for energy, all options have to be kept open, with fossil fuels, nuclear and hydro dominating the energy mix for the next decades, and 'new' renewables coming in only slowly. Considering the resulting strain on the environment, and looking at existing disparities in energy supply, the next few decades will not be free of tensions. A turning point may appear in the mid 21st century with world population coming to a halt, distinctly improved energy efficiency also in the Developing World, and with new technologies available. Thus, mainly challenges will determine the first half of the century, whereas chances are on hand for the second half of the century - if we act now. The single most important instrument to meet these challenges and to take advantage of the chances is a concentrated move towards energy efficiency and innovation, supported by market reform and appropriate regulation.

Full Text Available Media consumption is commonly seen as a major way of appropriating languages and cultures. Availability and accessibility of material are essential conditions for developing plurilingual cultural practices. Transnational circulation of cultural goods has reached a particular intensity in today’s world but is still marked by deep language inequalities. Combining sociolinguistic, language education, cultural sociology, and multiliteracy approaches, this study examines how plurilingual readers access books in their different languages. This qualitative analysis is based on 24 in-depth interviews with both migrant and non-migrant adults living in Western Europe. The findings indicate that printed and digital books in dominant languages circulate more easily, and through more visible and formal channels than books in dominated languages. In addition, the local and online book supply in dominant languages is generally cheaper and more varied, thus being more attractive. However, a wider range of means of access to books, and the active participation of the readers themselves in the circulation of cultural goods enable book-reading practices in less disseminated languages. Pedagogical recommendations for language teachers to encourage autonomous cultural practices among learners according to global evolutions and local specificities are provided.

Two thirds of Canadian adults participate in the workforce. Their health and that of their families can be markedly affected by the availability of paid sick leave, paid leave to care for family members' health and paid parental leave. We gathered data from all Canadian provinces and territories on these essential leave policies and compared Canadian policies with data collected on 186 United Nations (UN) countries. While Canada pays sickness benefits for 15 weeks for serious illnesses, globally at least 90 countries provide benefits for at least 26 weeks or until recovery. Moreover, within Canada only Saskatchewan and Quebec guarantee job protection if sick leave lasts over 12 days. The federal government guarantees Canadian workers six weeks of paid leave to provide care or support to gravely ill family members. Only 39 countries guarantee such leave with pay. Most, but not all, provinces guarantee workers' job protection during compassionate care leave. Eligibility for job protection during parental leave varies across the country from having no restrictions to requiring at least one year of service. Compared with Canada, many countries offer a longer duration of paid sick leave for employees and replace a higher percentage of wages lost. Internationally, Canada performs well in having policies that guarantee paid leave to care for dependants with serious illnesses, but it lags behind in the provision of paid leave to address the health needs of children or family members' with non-life-threatening conditions. Finally, while paid parental leave is of adequate duration, the wage replacement rate lowers its accessibility to families with limited means.

As described in a recently released report of the Forum of International Respiratory Societies, four of the leading causes of death in the world are chronic obstructive pulmonary disease, acute respiratory tract infections, lung cancer, and tuberculosis. A fifth, asthma, causes enormous global morbidity. Not enough progress has been made in introducing new therapies and reducing disease burden for these illnesses in the last few decades, despite generous investments and some notable progress in biomedical research. Four external and modifiable drivers are responsible for a substantial percentage of the disease burden represented by the major lung diseases: tobacco, outdoor air pollution, household air pollution, and occupational exposures to lung toxins. Especially in low- and middle-income countries, but in highly developed economies as well, pressures for economic development and lax regulation are contributing to the continued proliferation of these drivers. Public health approaches to the most common lung diseases could have enormous effects on reducing morbidity and mortality. There must be increased advocacy from and mobilization of civil society to bring attention to the drivers of lung diseases in the world. The World Health Organization should negotiate accords similar to the Framework Convention on Tobacco Control to address air pollution and occupational exposures. Large increases in funding by government agencies and nongovernmental organizations around the world are needed to identify technologies that will reduce health risks while allowing populations to enjoy the benefits of economic development. This paradigm, focused more on public health than on individual medical treatment, has the best chance of substantial reduction in the burden of lung disease around the world in the next several years.

Coffee is one of the most important global crops and provides a livelihood to millions of people living in developing countries. Coffee species have been described as being highly sensitive to climate change, as largely deduced from modeling studies based on predictions of rising temperatures and changing rainfall patterns. Here, we discuss the physiological responses of the coffee tree in the context of present and ongoing climate changes, including drought, heat, and light stresses, and interactions between these factors. We also summarize recent insights on the physiological and agronomic performance of coffee at elevated atmospheric CO 2 concentrations and highlight the key role of CO 2 in mitigating the harmful effects of heat stress. Evidence is shown suggesting that warming, per se, may be less harmful to coffee suitability than previously estimated, at least under the conditions of an adequate water supply. Finally, we discuss several mitigation strategies to improve crop performance in a changing world.

Abstract Background Full floristic data, tree demography, and biomass estimates incorporating non-tree lifeforms are seldom collected and reported for forest plots in the tropics. Established research stations serve as important repositories of such biodiversity and ecological data. With a canopy crane setup within a tropical lowland rainforest estate, the 42-ha Daintree Rainforest Observatory (DRO) in Cape Tribulation, northern Australia is a research facility of international significance. We obtained an estimate of the vascular plant species richness for the site, by surveying all vascular plant species from various mature-phase, remnant and open vegetation patches within the site. We also integrate and report the demography and basal areas of trees ≥ 10 cm diameter at breast height (dbh) in a new 1-ha core plot, an extension to the pre-existing forest 1-ha plot under the canopy crane. In addition, we report for the canopy crane plot new demography and basal areas for smaller-size shrubs and treelets subsampled from nine 20 m2 quadrats, and liana basal area and abundance from the whole plot. The DRO site has an estimated total vascular plant species richness of 441 species, of which 172 species (39%) are endemic to Australia, and 4 species are endemics to the Daintree region. The 2 x 1-ha plots contains a total of 262 vascular plant species of which 116 (1531 individuals) are tree species ≥ 10 cm dbh. We estimate a stem basal area of 34.9 m2 ha-1, of which small stems (tree saplings and shrubs rainforests globally, our meta-analysis shows that DRO forests has a comparatively high stem density and moderate species diversity, due to the influence of cyclones. These data will provide an important foundation for ecological and conservation studies in lowland tropical forest. New information We present a floristic checklist, a lifeform breakdown, and demography data from two 1-ha rainforest plots from a lowland tropical rainforest study site. We also present a

Full Text Available This paper addresses the difficult and contradictory formation, consolidation and change processes of Latin American identity from an anthropological and holistic perspective and in the context of the emergence of the world-system from the conquest, colonization and independence struggles to its current reconfiguration in the midst of transnational globalization and the alternatives to it. This approach, which we could call dynamicsynthetic, sees identity as a constantly changing open process where contradictory dynamics interact in the construction-deconstruction-reconfiguration of Latin American identity in specific historical contexts. Our continental collective identity is analyzed as the result of complex strains among various civilizational dynamics and opposing geopolitical forces. Dialectical and dialogical processes work together to allow the “reconciliation” of converse and diverse elements in innovative syntheses and create a space for dialogue that fosters what is shared to have a positive interaction, without denying the specific. In other words, they facilitate the interaction between “we” and the “others”, the “national” and the “continental”, the “local” and the “global”, enabling a better understanding of our inclusive continental nominative process: “Hispano-American”, “Ibero-American”, “Latin American”
Full Text Available This article examines the changes towards more gender-sensitive interpretations of refugee status in international and national asylum laws and policies within the context of contemporary and historical global power relations. It also analyzes the changes in the language that can be found in the international UNHCR guidelines for the protection of women asylum seekers, U.S. national guidelines for assessing gender-related asylum claims, and recent U.S. court decisions assessing the gendered claims of women. Among the analyzed court cases, the focus is on the 2005 Mohammed case due to its problematic court decision and legal interpretations. Finding the Western countries’ instrumentalization of the international refugee protection system crucial for understanding the contemporary asylum system and women asylum seekers, the argument connects the historical conditions with the way in which the protection of women refugees from “cultural” gendered violence has been articulated in asylum politics in the U.S. The author’s overall findings are that international law, governmental organizations, and liberal women’s human rights NGOs have shaped the international and national legal protection of (women asylum seekers in such a way that it reproduces global inequalities in its representation of “Third World” women and their culture, uses women asylum seekers fleeing from violence for the purpose of exercising Western cultural superiority, and covers up the restrictive and racist Western asylum politics towards immigrants and asylum seekers.

In this article, we assess the potential development of energy use for future residential heating and air conditioning in the context of climate change. In a reference scenario, global energy demand for heating is projected to increase until 2030 and then stabilize. In contrast, energy demand for air conditioning is projected to increase rapidly over the whole 2000-2100 period, mostly driven by income growth. The associated CO 2 emissions for both heating and cooling increase from 0.8 Gt C in 2000 to 2.2 Gt C in 2100, i.e. about 12% of total CO 2 emissions from energy use (the strongest increase occurs in Asia). The net effect of climate change on global energy use and emissions is relatively small as decreases in heating are compensated for by increases in cooling. However, impacts on heating and cooling individually are considerable in this scenario, with heating energy demand decreased by 34% worldwide by 2100 as a result of climate change, and air-conditioning energy demand increased by 72%. At the regional scale considerable impacts can be seen, particularly in South Asia, where energy demand for residential air conditioning could increase by around 50% due to climate change, compared with the situation without climate change

Full Text Available The 2005 UNESCO Universal Declaration of Bioethics and Human Rights (UDBHR is specifically aimed at Africa and developing countries from other regions. The acceptance of this UNESCO instrument shows that global bioethics and human rights have become part of the bioethics discourse of today. It is clear that there is a certain affinity between human rights and bioethics, which makes such a link desirable. The value of this link lies in the fact that human rights facilitate a normative universal expansion of bioethical principles. The human rights framework provides bioethical principles with some authority and political influence, an instrument that can protect people in our broken context. Human rights practice and a reformed understanding of natural law both show that humanity can reach consensus on ethical principles such as those found in the UDBHR. Consensus on the theoretical foundation of human rights is not a prerequisite for the successful utilisation of these principles.

Bracatinga (Mimosa scabrella Bentham) is an important pioneer tree species in Ombrophylous Mixed Forest of Brazil and is widely used as an energy source. In traditional agroforestry systems, regeneration is induced by fire, then pure and dense stands known as bracatinga stands (bracatingais) are formed. In the first year, annual crops are intercalated with the seedlings. At that time the seedlings are thinned, then the stands remain at a fallow period and cut at seven years old. The species is very important mainly for small landowners. We studied the understory species that occur naturally during the succession over several years in order to manage them rationally in the future and maintain the natural vegetation over time. Three to 20 year-old Bracatinga stands were sampled between 1998 and 2011. All tree species with diameter at breast height (DBH) ≥ 5 cm were measured.The floristic evolution was assessed with respect to Sociability Index, the Shannon Diversity Index and the Pielou Evenness Index. Graphs of rank/abundance over different age groups were evaluated using the Kolmogorov-Smirnov test. We identified 153 species dispersed throughout the understory and tend to become aggregated over time.
Full Text Available Through of the analysis of the floristic composition of 16 plots of half an hectare in 12 sites where the Phyto-toma raimondii, Peruvian plantcutter exists, we found that richness and diversity of plants are not related to the abundance of the bird, neither the abundance of any of the 7 species used as food or for nestting, except the algarrobo (Prosopis pallida. The most frequent species in the 12 sites were algarroboProsopis pallida(92% of the sites, vichayoCapparis ovalifolia(67%, canutilloGrabowskia boerhaviifolia(58%, sapoteCapparis scabrida(58% and realengoMaytenus octogona(25%. Besides algarrobo, canutillo seem to be a key species because in the plots where only three species occurred, those two were present. In the plots where canutillo was present, realengo did not more than expected statistically. It is alarming the decrease and few places or habitats for the occurrence and reproduction of the Peruvian plantcutter, a species considered in danger of extinction.

A floristic summary and analysis was performed on a list of the plant species that have been studied for the effects of gaseous and chemical air pollutants on vegetation in order to compare the species with the flora of North America north of Mexico. The scientific names of 2081 vascular plant species were extracted from almost 4000 journal articles stored in two large literature databases on the effects of air pollutants on plants. Three quarters of the plant species studied occur in North America, but this was only 7% of the total North American flora. Sixteen percent and 56% of all North American genera and families have been studied. The most studied genus is Pinus with 70% of the North American species studied, and the most studied family is the grass family, with 12% of the species studied. Although Pinus is ranked 86th in the North American flora, the grass family is ranked third, indicating that representation at the family level is better than at the genus level. All of the top ten families in North America are represented in the top 20 families in the air pollution effects literature, but only one genus (Lupinus) in the top ten genera in North America is represented in the top thirteen genera in the air pollution literature.

Identification of key metabolites for complex diseases is a challenging task in today's medicine and biology. A special disease is usually caused by the alteration of a series of functional related metabolites having a global influence on the metabolic network. Moreover, the metabolites in the same metabolic pathway are often associated with the same or similar disease. Based on these functional relationships between metabolites in the context of metabolic pathways, we here presented a pathway-based random walk method called PROFANCY for prioritization of candidate disease metabolites. Our strategy not only takes advantage of the global functional relationships between metabolites but also sufficiently exploits the functionally modular nature of metabolic networks. Our approach proved successful in prioritizing known metabolites for 71 diseases with an AUC value of 0.895. We also assessed the performance of PROFANCY on 16 disease classes and found that 4 classes achieved an AUC value over 0.95. To investigate the robustness of the PROFANCY, we repeated all the analyses in two metabolic networks and obtained similar results. Then we applied our approach to Alzheimer's disease (AD) and found that a top ranked candidate was potentially related to AD but had not been reported previously. Furthermore, our method was applicable to prioritize the metabolites from metabolomic profiles of prostate cancer. The PROFANCY could identify prostate cancer related-metabolites that are supported by literatures but not considered to be significantly differential by traditional differential analysis. We also developed a freely accessible web-based and R-based tool at http://bioinfo.hrbmu.edu.cn/PROFANCY. PMID:25153931

Research on Indian nurses has focused on their participation as global migrant workers for whom opportunities abroad act as an incentive for many to migrate overseas. However, little is known about the careers of Indian nurses, or the impact of a globalized health care market on nurses who remain and on the profession itself in India. To explore nurses' accounts of entry into nursing in the context of the globalisation of the nursing profession in India, and the salience of 'migration' for nurses' individual careers. Qualitative interview study (n=56). The study drew on interviews with 56 nurses from six sites in Bangalore, India. These included two government hospitals, two private hospitals, a Christian mission hospital, a private outpatient clinic and two private nursing colleges. Participants were selected purposively to include nurses from Christian and Hindu backgrounds, a range of home States, ages and seniority and to deliberately over-recruit (rare) male nurses. Interviews covered how and why nurses entered nursing, their training and career paths to date, plans for the future, their experiences of providing nursing care and attitudes towards migration. Data analysis drew on grounded theory methods. Nursing is traditionally seen as a viable career particularly for women from Christian communities in India, where it has created inter-generational 'nurse families'. In a globalizing India, nursing is becoming a job 'with prospects' transcending traditional caste, class and gender boundaries. Almost all nurses interviewed who intended seeking overseas employment envisaged migration as a short term option to satisfy career objectives - increased knowledge, skills and economic rewards - that could result in long-term professional and social status gains 'back home' in India. For others, migration was not part of their career plan: yet the increases in status that migration possibilities had brought were crucial to framing nursing as a 'suitable job' for a
Full Text Available The “employer brand” concept has recently entered the field of human resources. This study aims to analyze how the two national TV broadcasters Antena 1 and Antena 3 apply this concept and how the employer brand customizes and enhances the distinctive values of the organization through its employees. Ambler and Barrow defined for the first time the term of “employer brand”, in the Journal of Brand Management in 1996. We conducted an exploratory research in order to identify the presence of branding activities. We used the survey, the interview and the analysis of documents promoting the image of the organization. Correlated results demonstrate that high employee satisfaction leads to enhancing performance, which increases the audience ratings and improves the “brand equity”, thus making the human resource part of the organization brand and contributing to its success and international visibility. Given the early exploration of the concept, our research seeks to provide models of good practice for implementing this concept in the human resources policies of Romanian media institutions in the context of globalization.
Full Text Available The paper examines how the contextual approach to the conceptualization and the design of public administration systems can still be a viable alternative for today’s environment. By making reference to a proposed conceptual model, predominantly based on the cultural and social values in different contexts, the paper juxtaposes both the traditional Universalists and recent NPM approaches to the Contextual model by reviewing the literature on the impacts of globalization and other recent developments in the area public administration and public policy both at the national and international levels. Special attention is paid to the significance of two major elements of ethical leadership and governance for creating a viable and sustainable public administration system that incorporates and emphasizes the process of political development and enhancing the civil society based on indigenous cultural and social values. The conclusion of the paper reinforces the validity and utility of the contextual approach by including these two major elements into its original conceptual framework.

Floristic and vegetation analysis in seven Mediterranean landslides led to the understanding of the successional processes occurring in different landslide disturbed sectors. Our study showed that in landslides that occurred between 1996 and 2010 there is a clear differentiation between the three main landslide sectors (scarp, main body and foot) concerning floristic composition, vegetation structure, floristic richness, successional processes and plant functional type. Additional differences were found between landslide areas and undisturbed agricultural areas adjacent to landslides. In this study 48 floristic relevés were made using a stratified random sampling design. The main landslide body exhibits the highest floristic richness whereas the landslide scarp has the lowest coverage rate and the highest presence of characteristic species from ruderal and strongly perturbed habitats. Finally, the landslide foot shows a late stage in the succession (maquis or pre-forest stage) with a high dominance of vines. We further discuss the importance of landslides as reservoirs of biodiversity especially for Mediterranean orchids. Copyright © 2016 Elsevier B.V. All rights reserved.

The Cape Floristic Region-the world's smallest and third richest botanical hotspot-has benefited from sustained levels of taxonomic effort and exploration for almost three centuries, but how close is this to resulting in a near-complete plant species inventory? We analyse a core component of this flora over a 250-year period for trends in taxonomic effort and species discovery linked to ecological and conservation attributes. We show that >40% of the current total of species was described within the first 100 years of exploration, followed by a continued steady rate of description. We propose that analysis provides important real-world insights for other hotspots in the context of global strategic plans for biodiversity in informing considerations of the likely effort required in attaining set targets of comprehensive plant inventories. In a time of unprecedented biodiversity loss, we argue for a focused research agenda across disciplines to increase the rate of species descriptions in global biodiversity hotspots.

Biological indicators are useful tools for the assessment of ecosystem condition. Multi-metric and multi-taxa indicators may respond to a broader range of disturbances than simpler indicators, but their complexity can make them difficult to interpret, which is critical to indicator utility for ecosystem management. Floristic Quality Assessment (FQA) is an example of a biological assessment approach that has been widely tested for indicating freshwater wetland condition, but less attention has been given to clarifying the factors controlling its response. FQA quantifies the aggregate of vascular plant species tolerance to habitat degradation (conservatism), and model variants have incorporated species richness, abundance, and indigenity (native or non-native). To assess bias, we tested FQA variants in open-canopy freshwater wetlands against three independent reference measures, using practical vegetation sampling methods. FQA variants incorporating species richness did not correlate with our reference measures and were influenced by wetland size and hydrogeomorphic class. In contrast, FQA variants lacking measures of species richness responded linearly to reference measures quantifying individual and aggregate stresses, suggesting a broad response to cumulative degradation. FQA variants incorporating non-native species, and a variant additionally incorporating relative species abundance, improved performance over using only native species. We relate our empirical findings to ecological theory to clarify the functional properties and implications of the FQA variants. Our analysis indicates that (1) aggregate conservatism reliably declines with increased disturbance; (2) species richness has varying relationships with disturbance and increases with site area, confounding FQA response; and (3) non-native species signal human disturbance. We propose that incorporating species abundance can improve FQA site-level relevance with little extra sampling effort. Using our

Floristic analyses (Principal Component Analysis and Analysis of Group Indicators) at the genus level were employed to characterize and compare seasonal forest formations in northeastern Brazil. The presence--absence of 248 genera of woody plants occurring in 24 floristic surveys was correlated with geomorphology and climatic variables. The analyses were consistent and point to the existence of two floristic groups of seasonal forests in the region, one more closely related to the Atlantic Coastal Forest (mata atlântica) and the other to the xerophytic formations (caatinga) of the region. The driest seasonal forest group experiences more than 8 dry months per year and/or a total annual rainfall of <1000 mm, and is found on the ancient eroded peaks in the semi-arid core and on the western slopes of the Borborema Plateau.

Full Text Available In the context of molecularly-dated phylogenies, inferences informed by ancestral habitat reconstruction can yield valuable insights into the origins of biomes, palaeoenvironments and landforms. In this paper, we use dated phylogenies of 12 plant clades from the Cape Floristic Region (CFR in southern Africa to test hypotheses of Neogene climatic and geomorphic evolution. Our combined dataset for the CFR strengthens and refines previous palaeoenvironmental reconstructions based on a sparse, mostly offshore fossil record. Our reconstructions show remarkable consistency across all 12 clades with regard to both the types of environments identified as ancestral, and the timing of shifts to alternative conditions. They reveal that Early Miocene land surfaces of the CFR were wetter than at present and were dominated by quartzitic substrata. These conditions continue to characterize the higher-elevation settings of the Cape Fold Belt, where they have fostered the persistence of ancient fynbos lineages. The Middle Miocene (13-17 Ma saw the development of perennial to weakly-seasonal arid conditions, with the strongly seasonal rainfall regime of the west coast arising ~6.5-8 Ma. Although the Late Miocene may have seen some exposure of the underlying shale substrata, the present-day substrate diversity of the CFR lowlands was shaped by Pliocene-Pleistocene events. Particularly important was renewed erosion, following the post-African II uplift episode, and the reworking of sediments on the coastal platform as a consequence of marine transgressions and tectonic uplift. These changes facilitated adaptive radiations in some, but not all, lineages studied.

Environmental heterogeneity of Belize and southern Mexico savannahs as well as their geographical location suggest that these plant communities share floristic elements, making them conducive to a phytogeographical analysis. The aim of this study was to analyse the floristic affinities of nine savannahs of Belize and southern Mexico and to explain the similarities and differences amongst them. A binary data matrix containing 915 species was built based on the authors' own collections and on nine floristic lists already published. A second data matrix, consisting of 113 species representing trees, was also used since most literature on neotropical savannahs has focused on this life form. In addition, the ten most species-rich families as well as the characteristic species present in more than five savannahs were analysed. Floristic similarities were calculated using the Jaccard index. Dendrograms obtained in both types of analysis showed clusters with low similarity values, corresponding to geographic locations formed by the savannahs of Belize-Tabasco and the Yucatan Peninsula. The floristic affinities of the savannahs may be explained in terms of heterogeneity in climate and physiography. The Yucatan Peninsula and Belize-Tabasco groups have differences in climate type and the amount of rainfall. In addition, the Yucatan Peninsula savannahs are established at the bottom of karstic valleys, while the Belize and Tabasco savannahs develop on extensive flatlands. The savannahs of Oaxaca have the same climate type and amount of rainfall as those of the Yucatan Peninsula but they are distributed along peaks and the slopes of shale hills. Fabaceae and Poaceae mainly dominated the local floras with 121 and 116 species each; remarkably, Melastomataceae was absent in the Yucatan Peninsula and Oaxaca. Nine species occurred in five to seven savannahs, confirming that they are widespread in both Belize and southern Mexico, and the Neotropics. Geographic location and floristic

Full Text Available The purpose. Critical social philosophy of education strives to provide a radical critique of existing models of education in the so-called Western models of democracy, creating progressive alternative models. In this context, the proposed integrative metatheory, which is based on classical and modern sources, concepts, aims for a comprehensive understanding and reconstruction of the phenomenon of education. One of the main tasks in the sphere of education’s democratization today, therefore, is to bring to education the results of restructuring and democratization of the society, to reflect changes in conditions of life and thinking, experience and transformation of subjectivity in the context of the technological revolution and globalization. Methodology. The critical social theory, which developed in the framework of contemporary neo-Marxism, indicates the need for a thorough analysis of society, however, unlike other theoretical concepts and research programs in order to analyze not a fixation and a statement of the existing social givens. On the contrary, critical analysis of society involves the identification of existing antagonistic, alienating factors that distort public communication.The subject of social analysis is the whole sphere of human and non-human nature, which interacts a person depend on it, the whole system of relations between society and nature, society and man, which is covered by the historical practice of conscious – "praxis".

Globally, climate is a fundamental driver of plant species' geographical distributions, yet we still lack a good understanding of climatic variation on tropical mountains and its consequences for elevational floristic patterns. In a seasonally dry region of southern Mexico, we analysed meteorological patterns along a large elevational gradient (0-3670 m a.s.l.) and examined their relationship with changes in floristic richness. Meteorological patterns were characterised using two data sources. First, climatic information was extracted from cartography and records from a few existing meteorological stations. Additionally, air temperature and humidity were recorded hourly during 1 year with data loggers, at sites representing 200-m elevation increments. Floristic information was extracted from a database containing 10,124 records of plant collections, and organized in 200-m elevational belts. Climatic charts distinguished three climate types along the gradient, all with marked rainfall seasonality, but these bore little correspondence with the information obtained with the data loggers. Mean annual air temperature decreased with increasing elevation (lapse rate of 0.542 °C 100 m-1). Thermal oscillation was minimum around 1400 m and increased towards both extremes of the gradient. Relative humidity opposed this pattern, with maxima between 800 and 1800 m, decreasing towards the highest elevations. An analysis of temperature frequency distributions revealed meteorological features undetectable from the annual or monthly means of this variable; despite an overall gradual transition of the proportions of time recorded at different temperatures, some changes did not conform to this pattern. The first discontinuity occurred between 1000-1200 m, where dominant temperatures shifted abruptly; also noticeable was an abrupt increase of the proportion of time elapsed at 0.1-10 °C between 2400 and 2600 m. Air temperature appears to be the most influential climatic factor

The Amazon forests are among the most diverse ecosystems in the planet. Although some countries of the Amazon Basin have a fairly complete record of their plants, in Colombia much effort is still needed to have a good idea of the plant diversity patterns and floristic composition. Three one-hectare vegetation-land plots (DBH? 10 cm) were established in Vaupes, Colombia, regarding three types of forest: Colina, Terraza (Terra Firme forests) and Igapo (periodically flooded). Plant diversity was estimated and floristic composition was described classifying the most important families and species. The highest diversity was found in Colina (Fisher's ? = 160.3), followed by Terraza (? = 78.4) and Igapo (? = 44.7). Fabaceae s.l. was the most important family of all plots, but in Terraza forest the importance of Arecaceae was similar to that of Fabaceae. Floristic composition was also remarkably different amongst the three forest types, especially Igapo, which was the most dissimilar. However, both Terra Firme forests showed strong floristic differences, which may be caused by differences in abiotic factors (i.e. soils). High plant diversity reported in this study agrees with the hypothesis that central and western Amazon forests are the most diverse of the Amazon Basin.

The goal of this study is to analyze the floristic patterns and the structure of disturbed and undisturbed upland forests, in Permanent Preservation Areas (PPAs) along the Moju river, in the Brazilian state of Pará. Trees with a diameter equal to or larger than 10cm at 1.30m from the ground (DBH) ≥10cm were analyzed for the upper stratum. For the middle stratum, individuals with DBH between 4.99 and 9.99cm were sampled. Forty-five families and 221 species were found in disturbed forests, and 43 families and 208 species in undisturbed forests. Floristic similarity was high between strata and between forest types, with values above 50%. Similarity was highest between middle strata. The most species-abundant families in undisturbed forests were Fabaceae, Sapotaceae, Chrysobalanaceae and Myrtaceae; the species with the highest density there were Eschweilera grandiflora, Licania sclerophylla and Zygia cauliflora. In disturbed forests, the dominant families were Fabaceae, Sapotaceae, Lecythidaceae and Melastomataceae. The Shannon-Wiener diversity index was 3.21 for undisturbed forests and 2.85 for disturbed forests. Non-metric multidimensional scaling (MDS) analysis did not group the forests by their floristic composition in both upper and middle strata. Overall, the PPA forests along the Moju river, even if disturbed, did not show major floristic changes but substantially change their structural characteristics.

This study aimed to conduct a floristic survey of riparian forest stretches in the Gramame river, state of Paraíba, Brazilian Northeast region, and analyze the floristic similarity with Brazilian riparian vegetation fragments. We found 136 species belonging to 106 genera and 43 families. The most representative families were: Fabaceae (19 spp., Cyperaceae (16 spp., and Rubiaceae (11 spp.. The predominant habit was herbaceous and the best represented biological spectrum was camephyte. Regarding the geographic distribution, there was a predominance of widely distributed species associated with the Neotropical province. The distribution patterns have shown a low similarity between areas, and largely distributed species stand out. Similarity analysis pointed out that the area was floristically related to other two coastal areas in the Brazilian Northeast and Southeast regions. Only species typically related to estuarine environments might explain the floristic connections detected.

A case study was conducted on the forest ecosystem in the Baishuijiang River basin of China to reveal the influences of environmental factors and human disturbance on the floristic characteristics and biodiversity patterns. Field surveys of the floristic composition, environmental factors, and disturbance factors were conducted along an elevation gradient, and the relationships between biodiversity pattern and environmental factors were analyzed using CCA (canonical correspondence analysis). The results showed that the floristic composition of higher plants consisted of 197 families, 796 genera, 2165 species, 19 subspecies, 239 varietas, and 12 forma, and it was characterized by the multi-geographic composition and by the transition from tropical to temperate zones. Along an elevation gradient, the variations in α and β diversity were best described by a bimodal curve, and the peak values occurred at middle elevations. The CCA indicated that the elevation had the greatest influence on the biodiversity pattern, followed by the topographic index, slope direction, slope, slope position, slope shape, and vegetation coverage. In addition, human disturbance has greatly impacted the floristic composition and biodiversity patterns, and the biodiversity indices were higher with intermediate disturbance at middle elevations compared to higher and lower disturbances at low and high elevations, respectively. This reflected a disturbance-diversity pattern and thus revealed the obvious importance to maintain the intermediate disturbance for biodiversity conservation.

A multitemporal analysis on a humid area in Rome's archaeological site is presented; the floristic data are used as bioindicators for main environmental changes over the last 50 years. By comparing the structural, biogeographical and ecological features of today's florula with the ones of a 1955 survey, and by assessing the new, the rare and the locally disappeared species, it was possible to define and analyse the main floristic changes and their ecological meaning for this site. Our results show that the floristic richness of the area did not differ significantly from 1955. However, the species composition has changed considerably: over 40% of the species have disappeared. More than half of these were rare and typical of humid environments. Approximately the same number of species has appeared but these are mainly ruderal and widespread entities, with the overall result being a progressive and general vulgarization of the local flora. Finally, we analyse the main reasons, linked for the most part to human activities, which led to the reported floristic changes.

In disturbed forests, the dominant families were Fabaceae, Sapotaceae, Lecythidaceae and Melastomataceae. The Shannon-Wiener diversity index was 3.21 for undisturbed forests and 2.85 for disturbed forests. Non-metric multidimensional scaling (MDS analysis did not group the forests by their floristic composition in both upper and middle strata. Overall, the PPA forests along the Moju river, even if disturbed, did not show major floristic changes but substantially change their structural characteristics.

Full Text Available Repeated slash and burn cultivation creates wasteland with thorny shrubs, which then takes a long time to become secondary forests through serial stages of succession. Assisted natural regeneration through silvicultural management is a useful restoration method to accelerate succession. This survey evaluates the effectiveness of a simple silvicultural method for the rehabilitation of degraded lands to productive forest, thereby increasing floristic wealth. Field-based comparative analyses of floristic composition were carried out at a silviculturally managed forest (Popham Arboretum and a primary forest (Kaludiyapokuna Forest Reserve which is located in Dambulla in Sri Lanka. Floristic analysis was used to examine the effectiveness of silvicultural techniques for successful restoration of degraded forest in the dry zone. Nine 20 m × 20 m plots in each forest were enumerated and the vegetation ≥ 10 cm girth at breast height was quantitatively analyzed. Cluster analysis resulted in five distinguishable clusters (two from Popham Arboretum and three from Kaludiyapokuna Forest Reserve. Similarity indices were generated to compare the plots within and between sites. Floristic similarity was higher in forest reserve plots compared to arboretum plots. A total of 72 plant species belonging to 60 genera and 26 families were recorded from the study sites. Of the recorded species, Grewia damine and Syzygium cumini (Importance Value Index, IVI = 24 and 23 respectively were the ecologically co-dominant taxa at the Popham Arboretum. In contrast, Mischodon zeylanicus (IVI = 31, Schleichera oleosa (IVI = 25 and Diospyros ebenum (IVI = 21 were the abundant taxa in the forest reserve.

Floristic quality assessment is potentially an important tool for conservation efforts in the northern Great Plains of North America, but it has received little rigorous evaluation. Floristic quality assessments rely on coefficients assigned to each plant species of a region’s flora based on the conservatism of each species relative to others in the region. These “coefficients of conservatism” (C values) are assigned by a panel of experts familiar with a region’s flora. The floristic quality assessment method has faced some criticism due to the subjective nature of these assignments. To evaluate the effect of this subjectivity on floristic quality assessments, we performed separate evaluations of the native plant communities in a natural wetland complex and three restored wetland complexes. In our first assessment, we used C values assigned “subjectively” by the Northern Great Plains Floristic Quality Assessment Panel. We then performed an independent assessment using the observed distributions of species among a group of wetlands that ranged from highly disturbed to largely undisturbed (data-generated C values). Using the panel-assigned C values, mean C values (C¯">C¯C¯) of the restored wetlands rarely exceeded 3.4 and never exceeded 3.9, with the highest values occurring in the oldest restored complex; all but two wetlands in the natural wetland complex had a C¯">C¯C¯ greater than 3.9. Floristic quality indices (FQI) for the restored wetlands rarely exceeded 22 and usually reached maximums closer to 19, with higher values occurring again in the oldest restored complex; only two wetlands in the natural complex had an FQI less than 22. We observed that 95% confidence limits for species richness and percent natives overlapped greatly among wetland complexes, whereas confidence limits for both C¯">C¯C¯ and FQI overlapped little. C¯">C¯C¯ and FQI values were consistently greater when we used the datagenerated C values than when we used the

This report examines economic implications for sustainable forest management of globalization and related structural changes in the forest sector of the United States. Globalization has accelerated structural change in the U.S. forest sector, favored survival of larger and more capital-intensive enterprises, and altered historical patterns of resource use.
Globalization is often referred to as external to education - a state of affair facing the modern curriculum with numerous challenges. In this paper it is examined as internal to curriculum; analysed as a problematization in a Foucaultian sense. That is, as a complex of attentions, worries, ways...... of reasoning, producing curricular variables. The analysis is made through an example of early childhood curriculum in Danish Pre-school, and the way the curricular variable of the pre-school child comes into being through globalization as a problematization, carried forth by the comparative practices of PISA...

The rapid globalization of the world economy is causing fundamental changes in patterns of trade and finance. Some economists have argued that globalization has arrived and that the world is â€œflatâ€ . While the geographic scope of markets has increased, the author argues that new patterns of trade and finance are a result of the discrepancies between â€œoldâ€ countries and â€œnewâ€ .

Full Text Available Dehesa is a remarkable agroforestry system, which needs the implementation of sustainable production systems in order to reduce its deterioration. Moreover, its livestock farms need to adapt to a new global market context. As a response, the organic livestock sector has expanded not only globally but also in the region in search for increased overall sustainability. However, conversions to the organic system have been commonly carried out without analyzing farms’ feasibility to do so. This analysis is necessary before implementing any new production system in order to reduce both the diversity of externalities that the variety of contexts leads to and the vulnerability of the DDehesa ecosystem to small management changes. Within this context and in the face of this gap in knowledge, the present paper analyzes the ease of such conversions and the farms’ chances of success after conversion in the face of global changes (market and politics. Different aspects (“areas of action” were studied and integrated within the Global Conversion Index (GCI, and the legal requirement for European organic farming, organic principles, future challenges for ruminants’ production systems, as well as the lines of action for the post-2013 CAP (Common Agricultural Policy and their impacts on the beef cattle sector were taken into account. Results revealed that farms must introduce significant changes before initiating the conversion process, since they had very low scores on the GCI (42.74%, especially with regard to health and agro-ecosystem management (principle of Ecology. Regarding rearing and animal welfare (principle of justice/fairness, farms were close to the organic system. From the social point of view, active participation in manufacturing and marketing of products should be increased.

Full Text Available In order to assess the prevalence of pesticide contamination and the risk of florists’ exposure when handling cut flowers, sampling and analysis of 90 bouquets of the most commonly sold cut flowers in Belgium (50 bouquets of roses; 20 of gerberas, and 20 of chrysanthemums were carried out. The bouquets were collected from 50 florists located in the seven largest cities of Belgium (Antwerp, Brussels, Charleroi, Ghent, Leuven, Liege, and Namur and from five supermarkets located in the different regions. To have a better understanding of the route of exposure and professional practices a questionnaire was also addressed to a group of 25 florists who volunteered to take part in the survey. All florists were interviewed individually when collecting the questionnaire. The residual pesticide deposit values on cut flowers were determined in an accredited laboratory using a multi-residue (QuEChERS Quick Easy Cheap Effective Rugged Safe method and a combination of gas chromatography (GC and liquid chormatograhphy (LC analysis. A total of 107 active substances were detected from all samples; i.e., an average of about 10 active substances per bouquet. The most severely contaminated bouquet accumulated a total concentration of residues up to 97 mg/kg. Results show that roses are the most contaminated cut flowers; with an average of 14 substances detected per sample and a total concentration per rose sample of 26 mg/kg. Some active substances present an acute toxicity (acephate, methiocarb, monocrotophos, methomyl, deltamethrin, etc. and exposure can generate a direct effect on the nervous system of florists. Nevertheless, fungicides (dodemorph, propamocarb, and procymidone were the most frequently detected in samples and had the highest maximum concentrations out of all the active substances analysed. Dodemorph was the most frequently detected substance with the highest maximum concentration (41.9 mg/kg measured in the rose samples. It appears from the

The strengthening and westward shift of Pacific Walker Circulation (PWC) is observed during the recent decades. However, the relative roles of global warming and natural variability on the change in PWC unclearly remain. By conducting numerical atmospheric general circulation model (AGCM) experiments using the spatial SST patterns in the global warming and natural modes which are obtained by the multi-variate EOF analysis from three variables including precipitation, sea surface temperature (SST), and divergent zonal wind, we indicated that the westward shift and strengthening of PWC are caused by the global warming SST pattern in the global warming mode and the negative Interdecadal Pacific Oscillation-like SST pattern in the natural mode. The SST distribution of the Pacific Ocean (PO) has more influence on the changes in equatorial zonal circulations and tropical precipitation than that of the Indian Ocean (IO) and Atlantic Ocean (AO). The change in precipitation is also related to the equatorial zonal circulations variation through the upward and downward motions of the circulations. The IO and AO SST anomalies in the global warming mode can affect on the changes in equatorial zonal circulations, but the influence of PO SST disturbs the Indian Walker circulation and Atlantic Walker circulation changes by the IO and AO. The zonal shift of PWC is found to be highly associated with a zonal gradient of SST over the PO through the idealized numerical AGCM experiments and predictions of CMIP5 models.

Full Text Available A current floristic and phytogeographic knowledge of native Mexican Bromeliaceae is presented. There are 22 genera of Bromeliaceae recorded from the country that include 326 species. The genus Ursulaea with 2 species is endemic to Mexico, while Hechtia with 48 of its 50 species has its principal center of diversity in the country. Tillandsia (175 spp, Hechtia (48 spp and Pitcairnia (46 spp are the genera with the greatest number of species. We present a comparative analysis of Mexican Bromeliaceae with that of other American regions that have recently published accounts for the Family, particularly the Mesomerican area, Venezuela, Ecuador, and the Guianas. Our results led us to the conclusion that all these floras should be considered as distinct. We observe a progressive decrease of the Simpson index value related with the remoteness of the Mexican area. A general analysis of the species numbers of Mexican bromeliad genera shows a distinct preference of the species for coniferous and oak forests, followed by tropical caducifolious forests. There is also significant representation of the family in other vegetation types such as cloud forests and tropical perennifolious forests. Generally Mexican Bromeliaceae species have scarce and sparse populations and in many cases they inhabit cliffs, bluffs and scarps in restricted areas. Concerning the geographic distribution of Mexican genera, 77.27 % are neotropical, 4.54% are South American and the remainder are Mexican and Central American. The generic endemism is very low (4.54 %, even if we extend the country limits to Megamexico sensu Rzedowsi (1991 it reaches only 13.63 %. The family endemism at specific level reaches 63.07 %. There are not available data about a specific analysis of the conservation status of Mexican Bromeliaceae, but we can point out that a great number of taxa are only known from the type collection or at the most from the type locality. This can perhaps be attributed in part to

Full Text Available ABSTRACT We submitted tree species occurrence and geoclimatic data from 59 sites in a river basin in the Atlantic Forest of southeastern Brazil to ordination, ANOVA, and cluster analyses with the goals of investigating the causes of phytogeographic patterns and determining whether the six recognized subregions represent distinct floristic units. We found that both climate and space were significantly (p ≤ 0.05 important in the explanation of phytogeographic patterns. Floristic variations follow thermal gradients linked to elevation in both coastal and inland subregions. A gradient of precipitation seasonality was found to be related to floristic variation up to 100 km inland from the ocean. The temperature of the warmest quarter and the precipitation during the coldest quarter were the main predictors. The subregions Sandy Coastal Plain, Coastal Lowland, Coastal Highland, and Central Depression were recognized as distinct floristic units. Significant differences were not found between the Inland Highland and the Espinhaço Range, indicating that these subregions should compose a single floristic unit encompassing all interior highlands. Because of their ecological peculiarities, the ferric outcrops within the Espinhaço Range may constitute a special unit. The floristic units proposed here will provide important information for wiser conservation planning in the Atlantic Forest hotspot.

Full Text Available There is currently significant dissatisfaction with conventional economic theory. The unreliability of conventional theory as a predictor of future economic possibilities of catastrophes emphasizes the need for a new paradigm of political economy. This paper provides a capsule of some of the important limitations and consequences of the “old” paradigm. It proposes the necessary elements of a new paradigm and it seeks to locate the new paradigm of political economy in terms of its global reach. This requires a richer contextual approach, with the tools of contextual mapping. It has as well a focus on the global process of effective power and the emerging rule of law based constitutive processes. This is a key to the role of decision and the architecture of decision-making in political economy. We conclude with the global to local implications of the Vicos Experiment in Peru. Finally, we stress the wider lens of focus to identify the real and not the illusory generation of value. The implications here facilitate real global democratization.
Full Text Available Lake Hamun is the largest freshwater resource in Iran with area of about 3820 km2. The present study aims to evaluate the floristic elements of the studied site. Plant samples were gathered from nature, from March to July at the growing season. Life form and chorotype of plants in Lake Hamun basin were investigated. Totally 128 plant species belonging to 80 genera and 30 families were identified. Families as Poaceae, Amaranthaceae and Fabaceae were the most dominant and frequent families. Considering biological types revealed that the most frequent forms were therophytes (61% and hemicryptophytes (17%. Floristic elements of the area were mainly Iranotouranian mixed with Saharo-Arabian and Sindu-Sudanian types, although multi- and bi- regional elements were also frequent. As the lake has recently become an international conserved area, the complete biological and ecological study of the site is a necessity.

Full Text Available One of the major plant communities identified in the Marakele National Park was forest. It became clear that this major forest community contained various forest and thicket communities. Relevés compiled in the forest were classified by TWINSPAN and Braun-Blanquet procedures identified six communities that are hierarchically classified. The forests dominated by Podocarpus latifolius and Widdringtonia nodiflora represent Afromontane Forests, whereas the Buxus macowanii-dominated dry forests and Olea europaea subsp. africana represent Northern Highveld Forests. A further group of communities represent thickets on termitaria with floristic affinities to both savanna and forest. The floristic composition and relationships of the forest and thicket communities are discussed.

Floristic studies provide valuable information on species richness in a region, and are particularly important if these areas belong to less studied environments, such as rocky outcrops, that may increase our knowledge. An important aspect for species colonization includes the mechanisms of diaspores dispersal in each community; these are essential to understand its structure, dynamics, and the regeneration process, and constitute an important tool for conservation. We developed a floristic survey on a granite-gneiss outcrop with the objective to increase the knowledge on plant diversity, through a floristic similarity analysis and detection of dispersal syndromes of sampled species, in a semi-arid region of Brazil. The fieldwork included collection and observation of the botanical material in loco during a period of 12 months. A total of 161 species belonging to 127 genera and 50 families of angiosperms were recorded. Fabaceae, Asteraceae and Convolvulaceae were the most representative families in number of species. Allophylus quercifolius (Mart.) Radlk. (Capparaceae) and Lafoensia pacari A. St.-Hil. (Lythraceae) represented new records for the State of Paraiba. The autochoric syndrome was the most representative, with 51.5 % of the recorded species; the anemochory was the second most representative syndrome with 26.7 % of the species; and finally the zoochory, representing 22.3 % of the species. The floristic similarity dendrogram showed the formation of three well-defined groups, whose area with the highest value (J = 33.2) is located in a Caatinga region called Cariri Paraibano, while the lowest value observed (J = 5.2), occurred in a settled area in two geomorphological units, a crystalline complex and a plateau region. These results may be due to the varying topographic conditions and edaphic heterogeneity arising from the specific geological formation of the region. These results yet demonstrate that, in rocky outcrops, abiotic syndromes represent an

Full Text Available This study was conducted in one region of a Seasonal Semideciduous Forest located in Tapurah (Mato Grosso State, Brazil with the aim of studying its floristic and structural composition. The fixed area method was applied to 10 × 250 m clusters, allocating and measuring five clusters with five subunits of 500 m² each. Species with a diameter at breast height greater than or equal to 10 cm were considered, and the sample sufficiency of the floristic survey was verified by a species accumulation curve. The similarities between the sample subunits were calculated by the Jaccard Similarity Index, and the species diversity with the Shannon Diversity Index and Pielou Evenness Index. The horizontal vegetation structure was characterized by density, frequency, dominance and the values of ecological importance, and diametric distribution were assessed by the Spiegel procedure. The families Vochysiaceae, Fabaceae and Sapindaceae were highly represented, and Qualea paraensis, Aspidosperma discolor and Matayba arborescens were the most important species. A high diversity and low ecological dominance were found, and the diametric structure of the trees presented a negative exponential distribution. In general, the structure, floristic composition and richness of vegetation correspond to a forest with stable and autoregenerative community after selective logging.

Full Text Available We analyzed the floristics and phytosociology of three palm swamps in the municipality of Bela Vista de Goiás, located in the state of Goiás, Brazil, in the central part of the Brazilian savanna (Cerrado. The floristic surveys were conducted monthly from May 2008 to April 2009, and 310 species were recorded (seven bryophytes, 15 ferns and 288 angiosperms. Bryophytes belonged to five genera and five families; ferns belonged to nine genera and nine families; and angiosperms belonged to 134 genera and 45 families. The angiosperm families with the highest species richness were Poaceae, Cyperaceae, Asteraceae, Eriocaulaceae, Xyridaceae, Lentibulariaceae, Melastomataceae, Rubiaceae and Fabaceae. The palm swamps were divided into three zones of increasing humidity: edge, middle and core. The number of species was higher in the middle than at the edge and the core. The families with the highest cover values were Cyperaceae, Melastomataceae, Arecaceae and Poaceae. Although the palm swamps had been disturbed to varying degrees, those disturbances did not affect the flora in the middle or the core. Floristic similarity was high between these two zones within a given palm swamp and low between the edges of different palm swamps.

Full Text Available The modern world is characterized by rapid integration and globalization processes, which have both a positive and a negative impact on the development of each country. National economies operate in the midst of global uncertainty, which is becoming the platform for the formation and implementation of the State economic policy, which should not only describe the conditions for strategic development of country but also adequately respond to the risks emerging out of the complex integration processes. The failure of the State to respond in a timely and adequate manner to the risks will result in lesser benefits and positive effects of integration processes than the impact of destabilizing factors. In such circumstances, economic sovereignty becomes the most important instrument of the State through which it can defend its national economic interests and form an effective economic policy.

Full Text Available The current accounting treatment of intangible assets is far from being generally accepted and defined in the knowledge-based economy. The recognition and evaluation of internally generated trademarks is an unsolved aspect of accounting regulations in the context of a transnationalization phenomenon. On the other hand, residual goodwill cannot reflect the intellectual capital and the company's knowledge which help optimize and create durable value. To prevent an alteration of the comparability of companies’ financial statements, it is recommended that financial analysts take into account the economic goodwill based on entity economic performance and not the accounting goodwill which follows accounting regulations.

We sampled woody plants with a diameter at breast height > 2.5 cm, excluding lianas, in 50 plots of 100 m². We selected studies of coastal forests in the states of Espírito Santo and Bahia to prepare a database that would reveal patterns of floristic variation among these areas. We used t wo-way indicator species analysis for the identification of the species that occur preferentially in the coastal forests of Espírito Santo. We identified 114 species belonging to 38 families. Species richness was greatest for Myrtaceae (26 species, followed by Fabaceae (10. The Shannon index for the study area was 3.96. The estimated total density was 3,330 individuals/ha and basal area was 32.02 m²/ha. The highest importance value (IV was for Protium heptaphyllum (IV, 23.4, indicating that it is characteristic of the Espírito Santo restinga. The results of our floristic analysis indicate that the species composition of the Itaúnas restinga is influenced by the so-called tabuleiro forests (coastal lowland forests on Tertiary deposits, which are most common in northern Espírito Santo. This seems to be the main factor responsible for the gradual reduction in floristic similarity between the restingas in the north of Espírito Santo and those in the south of the state, each constituting a distinct floristic block. In addition, we generated lists of species that occur preferentially in the restinga and

Weather conditions throughout the year have a greater influence than other factors (such as soil and cultivars) on grapevine development and berry composition. Temperature affects gene expression and enzymatic activity of primary and secondary metabolism which determine grape ripening and wine characteristics. In the context of the climate change, temperatures will probably rise between 0.3°C and 1.7°C over the next 20 years. They are already rising and the physiology of grapevines is already changing. These modifications exert a profound shift in primary (sugar and organic acid balance) and secondary (phenolic and aromatic compounds) berry metabolisms and the resulting composition of wine. For example, some Bordeaux wines have a tendency toward reduced freshness and a modification of their ruby color. In this context it is necessary to understand the impact of higher temperatures on grape development, harvest procedures, and wine composition in order to preserve the typicity of the wines and to adapt winemaking processes.

In a move indicative of the enthusiastic support of precision medicine, the U.S. President Barack Obama announced the Precision Medicine Initiative in January 2015. The global precision medicine ecosystem is, thus, receiving generous support from the United States ($215 million), and numerous other governments have followed suit. In the context of precision medicine, drug treatment and prediction of its outcomes have been important for nearly six decades in the field of pharmacogenomics. The field offers an elegant solution for minimizing the effects and occurrence of adverse drug reactions (ADRs). The Clinical Pharmacogenetics Implementation Consortium (CPIC) plays an important role in this context, and it aims at specifically guiding the translation of clinically relevant and evidence-based pharmacogenomics research. In this forward-looking analysis, we make particular reference to several of the CPIC guidelines and their role in guiding the treatment of highly relevant diseases, namely cardiovascular disease, major depressive disorder, cancer, and human immunodeficiency virus, with a view to predicting and managing ADRs. In addition, we provide a list of the top 10 crosscutting opportunities and challenges facing the fields of precision medicine and pharmacogenomics, which have broad applicability independent of the drug class involved. Many of these opportunities and challenges pertain to infrastructure, study design, policy, and science culture in the early 21st century. Ultimately, rational pharmacogenomics study design and the acquisition of comprehensive phenotypic data that proportionately match the genomics data should be an imperative as we move forward toward global precision medicine.

Full Text Available The goal of this paper is to identify the main criteria based on which e-Learning is used in organizational development with positive impact on business performance. Globalization has led to a multitude of changing markets, including learning and education. While quality production systems are implemented based on imposed standards, the business knowledge of employees varies in each country, mirroring the education system provided locally. The results are individually different knowledge gaps which challenged the learning industry to develop new strategies embedded in e-learning solutions. Major contribution to theory and practice on combining vision and spoken learning is brought by the work of psychologists and professors of education (Allen, 2012; Mayer, 2009; Hattie, 2009. Their innovations offered solutions for easy access to knowledge and implementation methods, as well as the documentation of the inclusion of videos in e-learning modules (Halls, 2012, offering teachers and trainers the possibility to create a live experience to trainees engaged in e-learning programs. This paper is based on data collected internationally and our empirical research undertaken in Romania, which is Europe’s main cluster for various production industries and world’s second for IT. Based on a questionnaire, we interviewed 18 multinational companies which perform parts of their business activities in Romania. Research results show that with the implementation of an effective e-learning strategy a 40-60% cost reduction, a complete measurability of the learning process and a standardized input and outcome of trainings has been achieved. This paper aims to highlight the impact of e-learning applied for business trainings within global developing companies. This study may be applicable to state education and thus could help to reduce the gap between local education and global expectations.

The potential and role of biomass resources in developing countries for addressing global climate change concerns are highlighted using India as a case study. Promotion of technologies, which use biomass more efficiently, is seen as a key strategy to integrate the concerns of both developing countries and developed countries. The role of various biomass technologies for improving rural infrastructure and village power is discussed in detail. A vision of establishing and running a chain of rural energy service companies, operating with a basket of devices and technologies, under the general provisions of CDM, is examined for commercialization and mainstreaming of biomass technologies which have achieved reasonable levels of maturity.

This chapter focuses attention on the human side of national and firm-level competitiveness in a dynamic global business environment. It introduces the concept of human capability development into the business economics literature, arguing that competitiveness depends on the overall capability...... of people, not only in a technical sense of having required work competencies and applying them efficiently but also on work attitude and behaviours that produce inter-human trust and collaboration. The human capability development construct is defined in terms of the following four sets of factors - (1...

In rapidly developing economies, like urban India, where road traffic injury rates are among the world's highest, the corporate workplace offers a non-traditional venue for road safety interventions. In partnership with a major multinational corporation (MNC) with a large Indian workforce, this study aimed to elicit local employee perspectives on road safety to inform a global corporate health platform. The safety attitudes and behaviours of 75 employees were collected through self-report survey and focus groups in the MNC offices in Bangalore and Pune. Analysis of these data uncovered incongruity between employee knowledge of safety strategies and their enacted safety behaviours and identified local preference for interventions and policy-level actions. The methods modelled by this study offer a straightforward approach for eliciting employee perspective for local road safety interventions that fit within a global strategy to improve employee health. Study findings suggest that MNCs can employ a range of strategies to improve the road traffic safety of their employees in settings like urban India including: implementing corporate traffic safety policy, making local infrastructure changes to improve road and traffic conditions, advocating for road safety with government partners and providing employees with education and access to safety equipment and safe transportation options.

Since the nineteen seventies, high- and low-income countries have undergone a pattern of transnational economic and cultural integration known as globalization. The weight of the available evidence suggests that the effects of globalization on labor markets have increased economic inequality and various forms of economic insecurity that negatively affect workers' health. Research on the relation between labor markets and health is hampered by the social invisibility of many of these health inequalities. Empirical evidence of the impact of employment relations on health inequalities is scarce for low-income countries, small firms, rural settings, and sectors of the economy in which "informality" is widespread. Information is also scarce on the effectiveness of labor market interventions in reducing health inequalities. This pattern is likely to continue in the future unless governments adopt active labor market policies. Such policies include creating jobs through state intervention, regulating the labor market to protect employment, supporting unions, and ensuring occupational safety and health standards.

There have been numerous global calls to action to utilize human resources information systems (HRIS) to improve the availability and quality of data for strengthening the regulation and deployment of health workers. However, with no normative guidance in existence, the development of HRIS has been inconsistent and lacking in standardization, hindering the availability and use of data for health workforce planning and decision making (Riley et al., 2012). CDC and WHO partnered with the Ministry of Health in several countries to conduct HRIS functional requirements analyses and establish a Minimum Data Set (MDS) of elements essential for a global standard HRIS. As a next step, CDC advanced a study to examine the alignment of one of the HRIS it supports (in Zimbabwe) against this MDS. For this study, we created a new data collection and analysis tool to assess the extent to which Zimbabwe's CDC-supported HRIS was aligned with the WHO MDS. We performed systematic "gap analyses" in order to make prioritized recommendations for addressing the gaps, with the aim of improving the availability and quality of data on Zimbabwe's health workforce. The majority of the data elements outlined in the WHO MDS were present in the ZHRIS databases, though they were found to be missing various applicable elements. The lack of certain elements could impede functions such as health worker credential verification or equitable in-service training allocation. While the HRIS MDS treats all elements equally, our assessment revealed that not all the elements have equal significance when it comes to data utilization. Further, some of the HRIS MDS elements exceeded the current needs of regulatory bodies and the Ministry of Health and Child Care (MOHCC) in Zimbabwe. The preliminary findings of this study helped inspire the development of a more recent HRH Registry MDS subset, which is a shorter list of priority data elements recommended as a global standard for HRIS.

Globalization has transformed the workplace at the same time that increasing numbers of children live in families in which all adults work for pay outside the home. Extensive research evidence demonstrates the importance of parental involvement in the early years of a child's life. Yet, parents caring for young children may face challenges in fulfilling both work and family responsibilities under current labor force conditions. In this article, we review the evidence on the importance of parental care for meeting young children's routine care needs, preventive health care needs, and curative medical treatment requirements. We examine the evidence regarding the impact of four policies in particular on young children's health and development: parental leave, breastfeeding breaks, early childhood care and education, and leave for children's health needs. Last, we examine the availability of these policies worldwide and discuss the potential economic implications.

Ocean acidification will have many negative consequences for marine organisms and ecosystems, leading to a decline in many ecosystem services provided by the marine environment. This study reviews the effect of ocean acidification (OA) on seagrasses, assessing how this may affect their capacity to sequester carbon in the future and providing an economic valuation of these changes. If ocean acidification leads to a significant increase in above- and below-ground biomass, the capacity of seagrass to sequester carbon will be significantly increased. The associated value of this increase in sequestration capacity is approximately £500 and 600 billion globally between 2010 and 2100. A proportionally similar increase in carbon sequestration value was found for the UK. This study highlights one of the few positive stories for ocean acidification and underlines that sustainable management of seagrasses is critical to avoid their continued degradation and loss of carbon sequestration capacity.

Fire and grazing are widely used to manage grasslands for conservation purposes, but few studies have evaluated the effects of these drivers on the conservation value of plant communities measured by the floristic quality index (FQI). Further, the influence of fire and grazing on soil properties and functions are difficult for land managers and restoration practitioners to assess. The objectives of this study were to: (1) quantify the independent and interactive effects of grazing and fire frequency on floristic quality in native tallgrass prairie to provide potential benchmarks for community assessment, and (2) to explore whether floristic quality can serve as an indicator of soil structure and function for more holistic ecosystem assessments. A factorial combination of fire frequencies (1-2, 4, and 20 years return intervals) and grazing (by bison or ungrazed) treatments were sampled for plant species composition, and for several indicators of soil quality in lowland tallgrass prairie. Floristic quality, diversity, and richness were higher in grazed than ungrazed prairie over all fire frequencies (P soil bulk density were also higher in grazed prairie soil over all fire frequencies (P soil N were positively correlated with FQI (P soil N pools are more strongly influenced by grazing than fire and that floristic quality can be an indicator of total soil C and N stocks in never cultivated lowland prairie.

Globalisation, scientific and technical progress are the basis of numerous innovative therapies for oncologic and non-oncologic diseases. It is another matter how much and by whom they are desired, and whether they have to be applied. When and how often? Innovative approaches should go towards simplification, universal distribution and application while at the same time analysis between the potential initial investment and the achieved final result should be made. An illustrative example for this is the targeted therapy for melanoma with its low baseline criteria or basic rules for its surgical treatment. Another example could be the confocal microscopy in the context of dysplastic nevus syndrome. Therapies for various autoimmune diseases should also be considered critically. In the current OAMJMS issue, as well as in some of our other ideas and statements reported also in OAMJMS, we are trying to answer at least to a part of these dilemmas, to provoke a critical point of view and to ask some simple questions: "Should any innovation be considered as a face value? Which is potentially beneficial for our patients? How could we regulate the processes to minimise the need for expensive medications for certain diseases? And, of course, we are also turning to our own mistakes by visualising the results of them!
The current neoliberal context of schools presents difficult challenges in addressing persistent issues of social inequalities. In this article, first, I argue that because of today's market-driven education, the rise of fitness testing in school physical education (PE) can be seriously detrimental to young people in general and to ethnic-minority young people's embodied identity in particular. Second, I explain how the racialization process circulated by the body-at-risk discourse, sustained by the media, and reproduced by high-stakes testing in PE forces ethnic-minority young people to construct their identities through White eyes, which alienates them from a consciousness of their own identity. Third, I explore the possible uses and pitfalls of Spivak's theoretical notion of "strategic essentialism" to put forward strategies to build a positive image of the "other" while attempting to avoid the erasure of difference. Fourth, I conclude the article by suggesting how Spivak's notion of strategic essentialism can be useful in rethinking current PE fitness practices.

Full Text Available Humans and fire form a coupled and co-evolving natural-human system in Mediterranean-climate ecosystems. In this context, recent trends in landscape change, such as urban sprawl or the abandoning of agricultural and forest land management in line with new models of economic development and lifestyles, are leading to new fire scenarios. A fire scenario refers to the contextual factors of a fire regime, i.e., the environmental, socio-economic and policy drivers of wildfire initiation and propagation on different spatial and temporal scales. This is basically a landscape concept linking territorial dynamics (related to ecosystem evolution and settlement patterns with a fire regime (ignition causes; spread patterns; fire frequency, severity, extent and seasonality. The aim of this article is to identify and characterize these land-based fire scenarios in Spain on a national and regional scale, using a GIS-based methodology to perform a spatial analysis of the area attributes of homogenous fire spread patterns. To do this, the main variables considered are: land use/land cover, fuel load and recent fire history. The final objective is to reduce territorial vulnerability to forest wildfires and facilitate the adaptation of fire policies and land management systems to current challenges of preparedness and uncertainty management.

In this article, I want to show that the securitization of health issues in the name of national interests led to the militarization of health care in the context of the war against terrorism. However, the connection between health and security also gave way to the emergence of the notion of human security, thus, converging with the human right to health approach and the cosmopolitan discourse on global health. These two perspectives on the relation between health and security lead to conflicting imperatives in the current state of counter-terrorism operations. I argue that when the securitization of health concerns in the name of national security conflicts with the provision of health care in the name of universal human rights, the higher moral end must trump the prudential one. Moreover, it is a duty to promote the human right to health when liberal democracies in foreign policies directly violate this moral ideal in the name of national security.

Tropical dry forests (TDFs) have been defined as a single biome occurring mostly in the lowlands where there is a marked period of drought during the year. In the Neotropics, dry forests occur across contrasting biogeographical regions that contain high beta diversity and endemism, but also strong anthropogenic pressures that threaten their biodiversity and ecological integrity. In Colombia, TDFs occur across six regions with contrasting soils, climate, and anthropogenic pressures, therefore being ideal for studying how these variables relate to dry forest species composition, successional stage and conservation status. Here, we explore the variation in climate and soil conditions, floristic composition, forest fragment size and shape, successional stage and anthropogenic pressures in 571 dry forest fragments across Colombia. We found that TDFs should not be classified solely on rainfall seasonality, as high variation in precipitation and temperature were correlated with soil characteristics. In fact, based on environmental factors and floristic composition, the dry forests of Colombia are clustered in three distinctive groups, with high species turnover across and within regions, as reported for other TDF regions of the Neotropics. Widely distributed TDF species were found to be generalists favored by forest disturbance and the early successional stages of dry forests. On the other hand, TDF fragments were not only small in size, but highly irregular in shape in all regions, and comprising mostly early and intermediate successional stages, with very little mature forest left at the national level. At all sites, we detected at least seven anthropogenic disturbances with agriculture, cattle ranching and human infrastructure being the most pressing disturbances throughout the country. Thus, although environmental factors and floristic composition of dry forests vary across regions at the national level, dry forests are equally threatened by deforestation, degradation

Full Text Available Few studies have adequately described the floristic and structural features of natural grasslands associated with shallow basalt soils in southern Brazil. This study was carried out on natural grazing land used for livestock production in the municipality of Santana do Livramento, in the Campanha region of the state of Rio Grande do Sul, Brazil. The aim of the study was to describe the floristic and structural diversity of the area. The floristic list obtained comprises 229 plant taxa from 40 botanical families, with a predominance of the families Poaceae (62, Asteraceae (28, Fabaceae (16 and Cyperaceae (12. The estimated diversity and evenness in the community were 3.00 and 0.874, respectively. Bare soil and rock outcrops accounted for 19.3% of the area, resulting in limited forage availability. Multivariate analysis revealed two well-defined groups among the sampling units. One group showed a high degree of internal aggregation, associated with deep soils, and was characterized by the presence of tussocks, whereas the other was less aggregate and was characterized by prostrate species growing on shallow soil. Ordination analysis indicated a gradient of moisture and of soil depth in the study area, resulting in different vegetation patterns. These patterns were analogous to the vegetation physiognomies described for Uruguayan grasslands. Overall, the grassland community studied is similar to others found throughout southern Brazil, although it harbors more winter forage species. In addition, the rare grass Paspalum indecorum Mez is locally dominant in some patches, behaving similarly to P. notatum Fl., a widespread grass that dominates extensive grassland areas in southern Brazil.

This paper presents a floristic survey of the wood component of cerrado s.s. (eastern face) and gallery forest (western face) areas carried out in the southern part of the Serra de Maracaju. The dispersal syndromes and floristic relations of this portion of the Serra were compared to those of other formations from different regions of Brazil. Between October 2007 and September 2008, monthly collections identified 144 species. As for dispersal syndromes, zoochory prevails, followed by autochory and anemochory. The gallery forest is a heterogeneous formation that shelters floristic elements shared with the Atlantic rain forest, the Amazonian forest, semi-deciduous seasonal forests and dry forests of the Pantanal. Low similarity between the two areas analyzed makes this region unique and suggests that the Serra de Maracaju is greatly influenced by the semi-deciduous seasonal forests of the southeastern region.

The emissions from thermal power plants have great phytotoxic effects on plants due to changes in their morphology and physiology. A floristic study has been conducted near the Thermal Power Station at Kota in Rajasthan to estimate the impact of emissions from the thermal power plant on biota. It is observed that the whole vegetation, especially the perennial trees and shrubs, growing near the station were severely damaged due to effects of air pollutants emitted from the Thermal Power Station. Analysis of the fly ash reveals its composition as composed of silica, alumina, iron oxide etc. (author)

Using complementary metrics to evaluate phylogenetic diversity can facilitate the delimitation of floristic units and conservation priority areas. In this study, we describe the spatial patterns of phylogenetic alpha and beta diversity, phylogenetic endemism, and evolutionary distinctiveness of the hyperdiverse Ecuador Amazon forests and define priority areas for conservation. We established a network of 62 one-hectare plots in terra firme forests of Ecuadorian Amazon. In these plots, we tagged, collected, and identified every single adult tree with dbh ≥10 cm. These data were combined with a regional community phylogenetic tree to calculate different phylogenetic diversity (PD) metrics in order to create spatial models. We used Loess regression to estimate the spatial variation of taxonomic and phylogenetic beta diversity as well as phylogenetic endemism and evolutionary distinctiveness. We found evidence for the definition of three floristic districts in the Ecuadorian Amazon, supported by both taxonomic and phylogenetic diversity data. Areas with high levels of phylogenetic endemism and evolutionary distinctiveness in Ecuadorian Amazon forests are unprotected. Furthermore, these areas are severely threatened by proposed plans of oil and mining extraction at large scales and should be prioritized in conservation planning for this region.

This study investigated the floristic composition and vegetation structure among different physiognomies in Ibodi Monkey forest, Ibodi, Osun State, Southwestern Nigeria. It also assessed the effects of anthropogenic activities on the forest with a view to providing detailed information on the floristic composition structure and diversity of species of the standing vegetation of the forest.Seven plots of 25 m x 25 m dimension were established within three physiognomies in the forest; Regrowth forest (RF), Tree fallow (TF) and Cocoa plantation. (CP) A total of 209 individual woody species were encountered in the seven plots. The highest density of woody species was found in the RF (1483), followed by CP (1072) and TF (792). The basal area in CP was the highest (21.44) while RF had the lowest (2.5567) with TF having an intermediate value (6.283). Crown area also indicated that RF had the highest cover while TF had the lowest crown area. Shannon-Wiener, Evenness, Richness indices followed the order RF > TF > CP. Similarity index was highest between CP and TF and lowest between RF and CP. The study concluded that Ibodi monkey forest has been influenced by human disturbance in form of selective logging of economic species, agriculture (shifting cultivation) and seasonal bush burning.

Full Text Available This survey aimed to describe the floristic composition and structure of the epiphytic community occurring in a terra firme forest in the city of Coari, Brazil, in the Amazon region. Data collection was performed with a 1.5 ha plot method, with which upland, slope and lowland habitats were sampled. All angiosperm epiphytes and their host plants (diameter at breast height > 10 cm were sampled. We recorded 3.528 individuals in 13 families, 48 genera and 164 species. Araceae was the most prevalent family with regard to the importance value and stood out in all related parameters, followed by Bromeliaceae, Cyclanthaceae and Orchidaceae. The species with the highest epiphytic importance values were Guzmania lingulata (L. Mez. and Philodendron linnaei Kunth. The predominant life form was hemiepiphytic. Estimated floristic diversity was 3.2 (H'. The studied epiphytic community was distributed among 727 host plants belonging to 40 families, 123 genera and 324 species. One individual of Guarea convergens T.D. Penn. was the host with the highest richness and abundance of epiphytes. Stems/trunks of host plants were the most colonized segments, and the most favorable habitat for epiphytism was the lowlands, where 84.1% of species and 48.2% of epiphytic specimens were observed.

Environmental conditions such as temperature, soil, photoperiodic factors and precipitation can determine the physical environment favoring the occurrence of given species and interfere with the reproductive period of plants. This work involved monthly excursions to a slope in the Serra de Maracaju between December 2009 and November 2010. Samples were collected in eight 25 x 50 m plots, transverse to the slope, totaling 1 ha sampled. Floristic richness included 79 species distributed into 58 genera and 31 families. Floristic Similarity Analysis and Principal Component Analysis showed the occurrence of two plant formations on the slope: seasonal deciduous forest and cerradão on the eutrophic soil of the slope. Flowering and fruiting occured in the rainy season; correlation with rainfall, mean temperature and photoperiod were negative for flowering and positive for fructification. Trees and bushes presented uniform flowering and a moderately seasonal fructification, which is unexpected in seasonal environments. We discuss the implications of the patterns found and make comparisons with others studies.

Full Text Available The upper montane forests in the southern and southeastern regions of Brazil have an unusual and discontinuous geographic distribution at the top of the Atlantic coastal mountain ranges. To describe the floristic composition and structure of the Atlantic Forest near its upper altitudinal limit in southeastern Brazil, 30 plots with 10 × 10 m were installed in three forest sites between 2,200 and 2,300 m.a.s.l. at Serra Fina. The floristic composition and phytosociological structure of this forest were compared with other montane and upper montane forests. In total, 704 individuals were included, belonging to 24 species, 15 families, and 19 genera. Myrsinaceae, Myrtaceae, Symplocaceae, and Cunoniaceae were the most important families, and Myrsine gardneriana, Myrceugenia alpigena, Weinmannia humilis, and Symplocos corymboclados were the most important species. The three forest sites revealed differences in the abundance of species, density, canopy height, and number of stems per individual. The upper montane forests showed structural similarities, such as lower richness, diversity, and effective number of species, and they tended to have higher total densities and total dominance per hectare to montane forests. The most important species in these upper montane forests belong to Austral-Antartic genera or neotropical and pantropical genera that are typical of montane areas. The high number of species shared by these forests suggests past connections between the vegetation in southern Brazilian high-altitude areas.

The global shortage of nursing professionals educated at baccalaureate level and beyond has been highlighted. Within America, services are preparing to treat an additional 32 million individuals under the Health Reform Bill. Within South Africa nursing education outputs do not meet demands. Countries are addressing these shortages by developing advanced nurse roles which require research degrees. To evaluate a national PhD programme within the context of a nurse education strategy and a national health insurance plan. A comparative effectiveness research design was employed. The setting was in South Africa between 2011 and 2013, a county with 51.7 million inhabitants. Participants included PhD candidates, programme facilitators, supervisors and key stakeholders. Data from a one day workshop was analysed using an inductive thematic analysis. Three years of evaluation reports were analysed. A mapping of the alignment of the PhD topics with healthcare priorities, and a comparison of the development of nurse education, of the national and international funder were conducted. The evaluation reports rated the programme highly. Three themes were identified from the workshop. These were, "support" with the sub-themes of burden, leveraging and a physical supportive place; "planning" with the sub-themes of the national context and practice, and "quality" with the sub-themes of processes and monitoring and evaluation. The mapping of PhD topics revealed that research was in line with development priorities. However, further investment and infrastructural changes were necessary to sustain the programme and its impact. To address sustainability and capacity in nations scaling up nurse education and healthcare insurance, it was recommended that top-up degrees for diploma educated nurses be developed along with, the implementation of a national nursing strategy for PhD and post-doctoral training encompassing clinical practice implementation and collaboration.

Florist chrysanthemum (Chrysanthemum morifolium) is the single largest beneficiary of mutation breeding efforts across the world. Nearly 267 mutants that are documented in Mutant Variety Database of IAEA belong to chrysanthemum. Conventional breeding in chrysanthemum is hampered due to excessive length of the ray florets preventing their pollination besides self-incompatibility. Mutation breeding therefore is more amenable to induce variability. (author)

Full Text Available National herbaria with significant historical plant collections are critical to tracking floristic changes and patterns, which include the introduction and spread of non-native plant species. To explore the importance of herbarium specimen data in understanding floristic changes in Zimbabwe, the plant collections housed by the National Herbarium (SRGH in Harare, Zimbabwe were utilized with historical specimens dating back to 1870. A list of naturalised plant taxa and collection data were compiled. A total of 2916 plant specimens were recorded, comprising of 401 taxa, 237 genera and 76 plant families. Twenty eight specimens (1.0% were collected between 1870 and 1908, prior to the establishment of the National Herbarium in 1909 and 123 specimens (4.2% were collected in the first 25 years of the establishment of the institute (1909â1934. Intensive collection of herbarium specimens of casual, naturalised and invasive alien plant species occurred between 1950 and 1970. This data demonstrates the utility of plant species data housed in the National Herbaria and how such data can be used to map floristic changes and patterns.

Full Text Available In today’s changing climate, the development of robust, accurate and globally applicable models is imperative for a wider understanding of Earth’s terrestrial biosphere. Moreover, an understanding of the representation, sensitivity and coherence of such models are vital for the operationalisation of any physically based model. A Global Sensitivity Analysis (GSA was conducted on the SimSphere land biosphere model in which a meta-modelling method adopting Bayesian theory was implemented. Initially, effects of assuming uniform probability distribution functions (PDFs for the model inputs, when examining sensitivity of key quantities simulated by SimSphere at different output times, were examined. The development of topographic model input parameters (e.g., slope, aspect, and elevation were derived within a Geographic Information System (GIS before implementation within the model. The effect of time of the simulation on the sensitivity of previously examined outputs was also analysed. Results showed that simulated outputs were significantly influenced by changes in topographic input parameters, fractional vegetation cover, vegetation height and surface moisture availability in agreement with previous studies. Time of model output simulation had a significant influence on the absolute values of the output variance decomposition, but it did not seem to change the relative importance of each input parameter. Sensitivity Analysis (SA results of the newly modelled outputs allowed identification of the most responsive model inputs and interactions. Our study presents an important step forward in SimSphere verification given the increasing interest in its use both as an independent modelling and educational tool. Furthermore, this study is very timely given on-going efforts towards the development of operational products based on the synergy of SimSphere with Earth Observation (EO data. In this context, results also provide additional support for the

Full Text Available We examined floristic patterns of ten seasonal semideciduous forest sites in southeastern Brazil and conducted a central sampling of one hectare for each site, where we took samples and identified all individual living trees with DBH (diameter at breast height, 1.30 m ≥4.8 cm. Arboreal flora totaled 242 species, 163 genera, and 58 families. Fabaceae (38 species and Myrtaceae (20 species were families with the largest number of species. Only Copaifera langsdorffii and Hymenaea courbaril occurred at all sites. Multivariate analysis (detrended correspondence analysis and cluster analysis using two-way indicator species analysis (TWINSPAN indicated the formation of a group containing seven fragments in which Siparuna guianensis was the indicator species. This analysis revealed that similarities between studied fragments were due mainly to the successional stage of the community.

FQA, which uses the conservatism of plant species for particular habitats and the species richness of plant communities, is a rapid method for the assessment of habitat quality. This method is based on species composition of quadrats and coefficients of conservatism for species which assigned by experts. Floristic Quality Index (FQI) that reflects vegetation integrity and degradation of a site can be calculated by a simple formula and be used for space-time comparison of habitat quality. It has been widely used in more than ten countries including the United States and Canada. This paper presented the principle, calculation formulas and application cases of this method, with the aim to provide a simple, repeatable and comparable method to assess habitat quality for ecological managers and researchers.

The Cape Floristic Region (CFR) displays high levels of plant diversity and endemism, and has received focused botanical systematic attention. In contrast, fungal diversity patterns and co-evolutionary processes in this region have barely been investigated. Here we reconstruct molecular phylogenies using the ITS and beta-tubulin gene regions of the ophiostomatoid fungi Gondwanamyces and Ophiostoma associated with southern African Protea species. Results indicate that they evolved in close association with Protea. In contrast to Protea, Ophiostoma species migrated to the CFR from tropical and subtropical Africa, where they underwent subsequent radiation. In both Gondwanamyces and Ophiostoma vector arthropods probably facilitated long-distance migration and shorter-distance dispersal. Although ecological parameters shaped most associations between ophiostomatoid fungi and Protea, there is congruence between fungal-host-associations and the systematic classification of Protea. These results confirm that the entire biotic environment must be considered in order to understand diversity and evolution in the CFR as a whole.

The floristic diversity of an oak Andean forest was studied at the national reserve Santuario de flora y fauna de Iguaque (Boyaca, Colombia). All individuals with DAP > 2 .5 were measured and registered in ten 50 x 2 m transects for a total of 0.1 ha. There were found 384 individuals, 53 species, 27 families and 34 genera; the most species-rich were Ericaceae (7), Lauraceae (5) and Myrsinaceae (5). The results show a forest with low diversity in which a few species predominate; the species with higher important value index (ivi) were quercus humboldtii (34 %), Weinmannia tomentosa (21.2 %), Clusia inesiana (4.8 %), Viburnum tinoides (4.7 %) and Ternstroemia meridionalis (4.6 %)

Transient global ischaemia induces cell death in the CA1 layer of the hippocampus. To evaluate the functional consequences, we performed context-dependent fear conditioning. Ischaemia was induced by 2-vessel-occlusion (2VO) in gerbils. On day 6 post ischaemia or sham procedures (in control group) gerbils were placed in a test chamber and after 3 min adaption time exposed to foot-shocks (training session). On the next day the animals were placed in the same test chamber without foot-shocks (test session). As a parameter for memory performance we used the standard method of measuring the total freezing time via a cumulative time-sampling procedure during the test session. We found a significant longer total freezing time in control animals than in ischaemic animals. In addition, however, we applied a more detailed analysis of (i) quantifying the number of freezing bouts, (ii) the average duration of single freezing bouts, (iii) the activity pattern during the training and test situation and (iv) we differentially evaluated all the single time segments of the experiment. These analyses revealed that although maintenance of freezing (duration of freezing bout) was significantly lower in ischaemic animals compared to controls, the initiation of freezing (number of freezing bouts) was not significantly different between the two groups during the test session. The activity scores of ischaemic and non-ischaemic gerbils were similar during the adaption time of the training session. The foot-shock, however, induced a significantly different pattern of behaviour in the ischaemic animals, which was selectively reproduced during the test session. In conclusion, ischaemic gerbils reacted to a fearsome thread with a behavioural pattern different from unlesioned animals and they revealed this specific foot-shock induced behaviour again during the test session. This indicated that CA1 hippocampal death did not interrupt memory performance but changed expression of fear. Therefore
One feature of climate change is the increasing heat exposure in many workplaces where efficient cooling systems cannot be applied. Excessive heat exposure is a particular problem for working people because of the internal heat production when muscle work is carried out. The physiological basis for severe heat stroke, other clinical effects, and heat exhaustion is well known. One feature of this health effect of excessive workplace heat exposure is reduced work capacity, and new research has started to quantify this effect in the context of climate change. Current climate conditions in tropical and subtropical parts of the world are already so hot during the hot seasons that occupational health effects occur and work capacity for many working people is affected. The Hothaps-Soft database and software andClimateCHIP.orgwebsite make it possible to rapidly produce estimates of local heat conditions and trends. The results can be mapped to depict the spatial distribution of workplace heat stress. In South-East Asia as much as 15% to 20% of annual work hours may already be lost in heat-exposed jobs, and this may double by 2050 as global climate change progresses. By combining heat exposure data and estimates of the economic consequences, the vulnerability of many low- and middle-income countries is evident. The annual cost of reduced labor productivity at country level already in 2030 can be several percent of GDP, which means billions of US dollars even for medium-size countries. The results provide new arguments for effective climate change adaptation and mitigation policies and preventive actions in all countries. © 2015 APJPH.

We provide and discuss a floristic survey of herbaceous and subshrubby aquatic and palustrine angiosperms of Viruá National Park (VNP). The VNP is located in the northern Amazon basin and displays phytophysiognomies distributed in a mosaic where these plants occur, as flooded forests, hydromorphic white-sand savannas, "buritizais" and waterbodies. After expeditions between February/2010 and January/2015 and the analysis of specimens from regional herbaria, we list 207 species of herbaceous and subshrubby aquatic and palustrine angiosperms for the VNP, distributed in 85 genera in 37 families. We recorded six new occurrences for Brazil, two for the northern Brazilian region and 21 for Roraima state. These new occurrences, added to the other species listed here, highlight the floristic similarity between the study site and the Guiana Shield, an adjacent phytogeographical unit and geologically related to the origin of white-sand savannas.

Full Text Available This paper presents the results of a floristic survey conducted on an Atlantic Forest fragment in the state of Alagoas, Brazil. Besides, the results of a similarity analysis between ten rainforest fragments from the Brazilian east-Northeast are presented. The floristic comparison was based on binary data with regard to the presence/ absence criterion for tree species identified in the ten fragments by means of Sørensen’s similarity index. A dendrogram was prepared using cluster analysis (Jaccard’s index and canonical correspondence analysis (CCA to test the abiotic factors, which can differently influence the similarity of fragments. The fragments showed low similarity indices. The variations were due to the fact that each fragment is a patch of what once was a continuous and heterogeneous region. However, the diversity loss, including the disappearance of more demanding species, can lead, in large-scale, to homogeneity and simplification of the northeastern Atlantic Forest.

Full Text Available The structure and floristic composition of riparian forest in the sub-Andean basin of the river Yumbillo in the municipality of Yumbo, Valle del Cauca, eastern slope of the western cordillera of the Andes, Colombia were analyzed. By 20 plots of 100 m2, in the altitude range between 1500 to 2235 m., Data was recorded in individuals with a diameter of a breast height (DBH > 10 cm, floristic composition and vertical and horizontal structure by calculation of abundance, frequency, dominance and importance value index (IVI. The floristic composition consisted of 825 individuals in 93 species, 71 genera and 50 botanical families, the dominant families were Myrtaceae, Lauraceae, Melastomataceae, Moraceae, Euphorbiaceae, Fagaceae, and Tiliaceae acanthaceae. The species were heavier ecological Truco (Hyeronima sp and the most frequent were Truco (Hyeronima scabrida, Roble (Quercus humboldtii and the “Higueron de nacimiento” (Ficus Apollinaris. The highest values corresponded to species of importance such as Truco (Hyeronima scabrida Arrayan (Myrcia sp, Nacedero (Trichanthera, Otobo (Dialyanthera lehemannii and Naranjuelo (Lacistema aggregatum. Vertical structure was categorized into three strata, 508 individuals in the I (3 and 16 m, 270 in the II (17 and 23 m and 47 in the Emerging (heights above 24 m. It was concluded that the riparian forest has high and typical pioneer species of forest recovery, highlighted the presence of Medio comino (Ocotea sp threatened timber species that can be part of ecological restoration actions and floristic enrichment in areas of riparian forest and watershed protection.

Full Text Available The objective of this study was to characterize the floristic composition, vegetation structure and ecological group of tree species in a cerradão forest (Cerrado biome of Palmas, Tocantins State, Brazil. A forest inventory was performed in an area of 10.15 hectares, using systematic sampling with plots of 400 m², in which all standing trees, alive and dead, that had diameter at breast height (DBH ≥ 5 cm were sampled and identified. A linear plateau regression model (LPR was used for sample sufficiency analysis. The Shannon index (H’ was used for assess the floristic diversity, and the Importance Value Index (IVI for assess the horizontal structure. The forest was classified in three strata according to vertical structure analysis. The LPR showed that the sampling size was adequate. The predominate species in the area were Myrcia splendens, Emmotum nitens and Qualea parviflora, and species from the families Fabaceae and Chrysobalanaceae. The pioneer (613 individuals ha-1 and climax (530 individuals ha-1 species were the predominating groups. Regarding the richness index, the number of climax (57 species and pioneer (25 species species stood out. The alpha floristic diversity was 3.35 nats individuals-1 and the Pielou equability value J = 0.76. The diametric distribution showed a negative and balanced exponential pattern. Regarding the vertical stratification, the smallest amount of individuals was in the upper stratum (13% and the highest in the mid stratum (63% and in the lower stratum (24%. The use of floristic composition tools with horizontal and vertical structure analysis was effective for understand the tree community, which may be considered structured and diverse, thus able to restructure possible disturbances when preserved.

Full Text Available This objective of this study was to characterize the floristic, structural, and ecological groups and to estimate the arboreal volume and biomass of a cerradão site in Palmas, Tocantins, Brazil. A forest inventory was conducted on 10.15 ha of the study area. Plots of 400-m2 were used for systematic sampling. All standing trees (dead or alive with a breast-height diameter (DHB greater than 5 cm were identified and measured. Floristic diversity and horizontal structure were assessed using the Shannon and importance value indices, respectively. Forest vertical structure was classified into three stratata and the tree species were categorized into ecological groups. Ninety tree volumes were rigorously cubed and weighed. Fresh- and dry biomass were sampled and estimated. Mathematical models were applied and adjusted to estimate tree volume and biomass. It was observed that the species Myrcia splendens and Emmotum nitens and the families Fabaceae and Chrysobalanaceae were dominant in our study site. The pioneer (613 individuals ha-1 and climax (530 individuals ha-1 tree species group predominated. The floristic diversity index was estimated as 3.35 nats ind- 1. The vertical structure analysis indicated fewer individuals in the superior stratum (13% compared to the medium (63% and inferior (24% stratum. The Schumacher and Hall model showed better results with regard to estimated forest production. Forest volume and biomass estimates were 126.71 m³ ha-1 and 61.67 Mg ha-1, respectively. The studied cerradão area had high floristic diversity and climax species predominated. Since this cerradão is in close proximity to the Amazon biome, its volume and biomass stocks were higher than those estimated for other cerradão and forest formations within the Cerrado biome.

The Constitution of the United States is a document for economic development written by people wary of government failure at the extremes, whether too heavy handed a central government or too loose a confederation. The strong central government favored by Hamilton, Industrialists and later by forward thinking men of the 19th century created a discontinuity wherein government institutions designed to facilitate agriculture were incapable of regulating corporations operating on a national scale, which made mineral and other natural resource exploitation needed to support industrialization enormously profitable. At the same time, Agriculturalists and other conservative citizens sought to control the economy by protecting their rural interests and power. The political institutional power remained with states as agriculturalists and industrialists struggled for economic superiority in the 19th century. As Agriculture moved west, Science warned of the dangers of extending Homesteading regulations into arid regions to no avail. The west was settled in townships without concern for watersheds, carrying capacity, or climatic variability. Gold seekers ignored the consequences of massive hydraulic mining techniques. The tension resident in the Constitution between strong local control of government (states' rights) and a strong central government (nationalism) provided no institutional context to resolve mining problems or other 19th century policy problems linked to rapid population expansion and industrialization. Environmental protection in the late 20th century has been the last wave of nationalized policy solutions following the institution-building blueprint provided by electoral successes in the Progressive, New Deal, and Great Society eras. Suddenly in the 21st century, scientific warnings of dangers again go unheeded, this time as evidence of global warming mounts. Again, tension in policy making exists in all political arenas (executive, legislative and judicial at

Full Text Available ABSTRACT Studies on the natural regeneration of tree species communities are important for providing information on forest development capacity. This research aimed to evaluate the floristic-structural variations of the tree regenerative component along a topographic gradient in an ecotonal area between a Mixed Ombrophilous Forest and a Deciduous Seasonal Forest of Santa Catarina, Brazil. 30 sampling units of which all regenerating tree species individuals have been identified were allocated in the forest fragment. The sampling units were then distributed along a topographic gradient into lower, intermediate and upper sectors. Abundance, richness, Shannon's diversity index (H' and Pielou's evenness index (J have been determined for both the whole community as for each sector. The community floristic-structural organization was verified by the means of the non-metric multidimensional scaling (NMDS, the indicator species analysis and the permutational multivariate analysis of variance (PERMANOVA. Abundance differences among sectors were analyzed through the Kruskal-Wallis test with post hoc multiple nonparametric test while richness differences were verified through rarefaction. Regenerating individuals density in the upper sector [129 (21.300 ind.ha-1] was lower than both in the lower [401 (63.800 ind.ha-1] and intermediary [241 (36.300 ind.ha-1] sectors. There was variation in the floristic-structural composition (p < 0.001 among topographic positions; the lower sector was the most distinct one and showed the highest number of indicator species.

Full Text Available Although biological surveys and taxonomic revisions provide key information to ecological and evolutionary studies, there is a clear lack of floristic and phytogeographic studies of the mountainous regions of Brazil, which harbor some of the most threatened plant ecosystems on the planet. Myrtaceae has been reported to be one of the most important families in the upland areas of Brazil, as well as in the Atlantic Forest Domain. In this study, we investigated the floristic composition of Myrtaceae throughout the Espinhaço Mountain Range and adjacent highlands of central-eastern Brazil, testing the following hypotheses: floristic similarity increases with geographic proximity; and species distribution is affected by geoclimatic variables. We performed statistical analyses using a database containing records of 199 species in 19 areas and of their respective geoclimatic variables. We also performed ordination analysis using non-metric multidimensional scaling (NMDS, the first and second axes of which explained 69% and 78% of the variation, respectively. The NMDS analysis demonstrated that variations in the Myrtaceae flora are highly sensitive to geoclimatic variables and geographic proximity. The NMDS ordination also showed a predominantly south-north gradient, as did the cluster analysis. This gradient was highly correlated with variations in rainfall and temperature, which are also associated with the three domains that coincide with the Espinhaço Mountain Range.
Structural and floristic changes of the understory vegetation of gamma-irradiated aspen and maple-aspen-birch (MAB) communities in northern Wisconsin were quantified by comparing the pre- and postirradiation floristic composition and vegetational cover. A size-dependent radiosensitivity was determined among three vegetational strata, the tall shrubs being the most sensitive, low shrubs intermediate, and herbs the most resistant. Corylus cornuta, whose nuclear characteristics indicated that it could be resistant, was very sensitive and was completely eliminated at exposures of 500 r/20-hr day or higher. The cover of Rubus strigosus, minimal before irradiation, increased manifold and accounted for most of the shrub cover 2 years after the conclusion of irradiation. Among herbs, Carex pensylvanica and Luzula acuminata were very resistant, and Trillium grandiflorum, Aralia nudicaulis, Oryzopsis asperifolia, and Clintonia borealis were very sensitive. The herbaceous stratum of the aspen type appeared more resistant than that of the MAB. This difference apparently resulted from differences in floristic composition of the two communities
National herbaria with significant historical plant collections are critical to tracking floristic changes and patterns, which include the introduction and spread of non-native plant species. To explore the importance of herbarium specimen data in understanding floristic changes in Zimbabwe, the plant collections housed by the National Herbarium (SRGH) in Harare, Zimbabwe were utilized with historical specimens dating back to 1870. A list of naturalised plant taxa and collection data were compiled. A total of 2916 plant specimens were recorded, comprising of 401 taxa, 237 genera and 76 plant families. Twenty eight specimens (1.0%) were collected between 1870 and 1908, prior to the establishment of the National Herbarium in 1909 and 123 specimens (4.2%) were collected in the first 25 years of the establishment of the institute (1909-1934). Intensive collection of herbarium specimens of casual, naturalised and invasive alien plant species occurred between 1950 and 1970. This data demonstrates the utility of plant species data housed in the National Herbaria and how such data can be used to map floristic changes and patterns.

In plant communities, the species distribution patterns and their relationships with environmental factors are of central importance in ecology. In San Luis Potosí of Mexico, woodlands of Pinus cembroides and P. johannis are sympatric, but P. cembroides tends to be located in South and Southwest slopes, in more disturbed sites; unlike, P. johannis, is mostly distributed in mesic areas, in North and Northeast slopes. The aim of this study was to analyze the influence of some physical factors on the floristic similarity of pinyon pine P. cembroides and P. johannis. The study area was located in the Sierra San Miguelito, San Luis Potosí, Mexico. We selected 40 sampling units spread over an area of 50km2. In each unit, we laid out two 20m long lines perpendicular to each other, in which we recorded cover data of the plant species intercepted. We developed two data matrices, the first one including cover values of 91 species, and the second one, considering seven topographical, climatic, and solar radiation variables. We applied cluster analysis and ordination to explore the influence of environmental variables on the floristic differentiation of pinyon pine woodlands. Clustering showed six groups, the first three characterized by P. cembroides. The ordination showed that variance represented by the first three axes was 65.9%. Axis 1 was positively correlated with altitude and negatively with mean annual temperature; axes two and three, showed low correlation with the variables tested. P. cembroides woodlands and accompanying flora tend to be located in lower altitude, higher mean annual temperature, and mainly in South-Southwestern slopes. In contrast, stands of P. johannis, mixed stands of P. johannis-P. cembroides, and Quercus potosina, were usually founded in greater altitudes, mean annual temperature slightly lower, and North-Northeastern exposure. The sites of these monospecific and mixed woodlands with associated species, indicators of environmental variables

Nestedness analysis can reveal patterns of plant composition and diversity among forest patches. For nested floral assemblages, the plants occupying any one patch are a nested subset of the plants present in successively more speciose patches. Elimination of sensitive understory plants with human disturbance is one of several mechanisms hypothesized to generate nonrandom, nested floral distributions. Hypotheses explaining distributions of understory plants remain unsubstantiated across broad landscapes of varying forest types and disturbance histories. We sampled the vegetation of 51 floodplain and 55 upland forests across Illinois (USA) to examine how the diversity, composition, and nestedness of understory floras related to their overstory growth and structure (basal area), and their overall floristic conservation value (mean C). We found that plant assemblages were nested with respect to site species richness, such that rare plants indicated diverse forests. Floras were also nested with respect to site mean C and basal area (BA). However, in an opposite pattern from what we had expected, floras of high-BA stands were nested subsets of those of low-BA stands. A set of early-successional plants restricted to low-BA stands, and more importantly, the absence of a set of true forest plants in high-BA stands, accounted for this pattern. Additionally, we observed a decrease in species richness with increasing BA. These results are consistent with the hypothesis that recovery of true forest plants does not occur concurrently with overstory regeneration following massive anthropogenic disturbance. Nestedness by site mean C indicates that high conservation value (conservative) plants co-occur in highly diverse stands; these forests are assumed to be less disturbed historically. Because site mean C was uncorrelated with BA, BA-neutral disturbances such as livestock usage are suggested as accounting for between-site differences in mean C. When considered individually

Full floristic data, tree demography, and biomass estimates incorporating non-tree lifeforms are seldom collected and reported for forest plots in the tropics. Established research stations serve as important repositories of such biodiversity and ecological data. With a canopy crane setup within a tropical lowland rainforest estate, the 42-ha Daintree Rainforest Observatory (DRO) in Cape Tribulation, northern Australia is a research facility of international significance. We obtained an estimate of the vascular plant species richness for the site, by surveying all vascular plant species from various mature-phase, remnant and open vegetation patches within the site. We also integrate and report the demography and basal areas of trees ≥ 10 cm diameter at breast height (dbh) in a new 1-ha core plot, an extension to the pre-existing forest 1-ha plot under the canopy crane. In addition, we report for the canopy crane plot new demography and basal areas for smaller-size shrubs and treelets subsampled from nine 20 m(2) quadrats, and liana basal area and abundance from the whole plot. The DRO site has an estimated total vascular plant species richness of 441 species, of which 172 species (39%) are endemic to Australia, and 4 species are endemics to the Daintree region. The 2 x 1-ha plots contains a total of 262 vascular plant species of which 116 (1531 individuals) are tree species ≥ 10 cm dbh. We estimate a stem basal area of 34.9 m(2) ha(-1), of which small stems (tree saplings and shrubs analysis shows that DRO forests has a comparatively high stem density and moderate species diversity, due to the influence of cyclones. These data will provide an important foundation for ecological and conservation studies in lowland tropical forest. We present a floristic checklist, a lifeform breakdown, and demography data from two 1-ha rainforest plots from a lowland tropical rainforest study site. We also present a meta-analysis of stem densities and species diversity from

Brazil holds most of the Atlantic Forest Domain and is also one of the Rubiaceae diversity centers in the Neotropics. Despite the urban expansion in the state of Rio de Janeiro, large areas of continuous vegetation with high connectivity degree can still be found. Recently, new Rubiaceae species have been described in the Rio de Janeiro flora, which present small populations and very particular distribution. The current paper analyzed the similarity in the floristic composition of the Rubiaceae in eight Atlantic Forest remnants of Rio de Janeiro state protected by Conservation Units. We also surveyed and set guidelines for conservation of microendemic species. The similarity analysis were based on previously published studies in Área de Proteção Ambiental de Grumari, Área de Proteção Ambiental Palmares, Parque Estadual da Serra da Tiririca, Parque Nacional do Itatiaia, Parque Nacional de Jurubatiba, Reserva Biológica de Poço das Antas, Reserva Biológica do Tinguá and Reserva Ecológica de Macaé de Cima - using the PAST software (“Paleontological Statistics”) with Sørensen coefficient. The floristic similarity analysis revealed two groups with distinct physiographic characteristics and different vegetation types. Group A consisted in two Restinga areas, Área de Proteção Ambiental de Grumari and Parque Nacional de Jurubatiba, which showed strong bootstrap support (98 %). Group B included forest remnants with distinct phytophisiognomies or altitudes, but with moderate bootstrap support. Low similarity levels among the eight areas were found due to the habitats’ heterogeneity. The current study pointed out 19 microendemic species from the Atlantic Forest, they present a single-site distribution or a distribution restricted to Mountain and Metropolitan regions of Rio de Janeiro state. Concerning the conservation status of microendemic species, discrepancies between the Catalogue of Flora of Rio de Janeiro and the Red Book of Brazilian Flora (two of
Full Text Available The Cape Floristic Region—the world’s smallest and third richest botanical hotspot—has benefited from sustained levels of taxonomic effort and exploration for almost three centuries, but how close is this to resulting in a near-complete plant species inventory? We analyse a core component of this flora over a 250-year period for trends in taxonomic effort and species discovery linked to ecological and conservation attributes. We show that >40% of the current total of species was described within the first 100 years of exploration, followed by a continued steady rate of description. We propose that <1% of the flora is still to be described. We document a relatively constant cohort of taxonomists, working over 250 years at what we interpret to be their ‘taxonomic maximum.’ Rates of description of new species were independent of plant growth-form but narrow-range taxa have constituted a significantly greater proportion of species discoveries since 1950. This suggests that the fraction of undiscovered species predominantly comprises localised endemics that are thus of high conservation concern. Our analysis provides important real-world insights for other hotspots in the context of global strategic plans for biodiversity in informing considerations of the likely effort required in attaining set targets of comprehensive plant inventories. In a time of unprecedented biodiversity loss, we argue for a focused research agenda across disciplines to increase the rate of species descriptions in global biodiversity hotspots.

Full Text Available A broad overview of published and unpublished ethnobotanical surveys in the Cape Floristic Region (the traditional home of the San and Khoi communities shows that the data is incomplete. There is an urgent need to record the rich indigenous knowledge about plants in a systematic and social responsible manner in order to preserve this cultural and scientific heritage for future generations. Improved methods for quantifying data are introduced, with special reference to the simplicity and benefits of the new Matrix Method. This methodology prevents or reduces the number of false negatives, and also ensures the participation of elderly people who might be immobile. It also makes it possible to compare plant uses in different local communities. This method enables the researcher to quantify the knowledge on plant use that was preserved in a community, and to determine the relative importance of a specific plant in a more objective way. Ethical considerations for such ethnobotanical surveys are discussed, through the lens of current ethical codes and international conventions. This is an accessible approach, which can also be used in the life sciences classroom.

The present work was carried out to evaluate the floristic checklist and environmental distinctiveness of Plants of Parachinar, Kurram Agency across the year during 2014- 2015. A total of 283 species of 222 genera among 85 families were recorded. Asteraceae with (29 Sp.) was the most dominant followed by, Poaceae with (20 Sp.), Papilionaceae, Lamiaceae each with (19 Sp.), Brassicaceae (16 Sp.), Solanaceae (13 Sp.), Rosaceae (9 Sp.) and Polygonaceae (7 Sp.). While Euphorbiaceae, Caryophylaceae and Pinaceaeeach with (6 Sp.) were the co-dominant taxa. Rest of the families possessed either 5 or fewer species. Based on the habitat 252 (89.04 percent) species were grew in dry places as wild mesophytes and xerophytes. Seventeen species (6.00 percent) were cultivated while 11 species (3.88 percent) were aquatic. There were 18 spiny species (6.36 percent). Among the perennial, majority were evergreen. Three species (1.06 percent) namely Cuscutareflexa, Periplocaaphylla and P. calophyllawere leafless. The leaf lamina was simple in 230 species (81.27 percent) and 50 species (17.66 percent) contained composite foliage. Therophytes107 (37.80 percent) and nanophanerophyte 47 species (16.66 percent) respectively were dominant life form groups. Leaf spectra revealed that nanophylls with 121 species (42.75 percent) and leptophylls with 89 (31.44 percent) were dominant leaf size classes. The vegetation was also characterized by microphylls and mesophylls but of least concern. (author)

Full Text Available To ensuresustainable use of natural forests, it is necessary the development of appropriate silvicultural techniques, based on the ecology of each type of plant formation. This study aimed to characterize the horizontal structure of a Miombo forest, located in Mocuba District, Zambézia province in Mozambique, aiming to provide technical support to the development of efficient management systems forest. The forest inventory was conducted using systematic sampling process, in which the horizontal structure was characterized taking into account the forest highlighting the floristic composition, phytosociology, species diversity and diameter distribution. In the area were foud 1090 individuals from 34 species, 29 genera and 12 families. The most important species in accordance with the ecological importance value index were Fabaceae family such BrachystegiaspiciformisBenth., CordylaafricanaLour., Burkeaafricana Hook., Pterocarpusangolensis DC., which make up about 58% of all species in the area. The behavior observed for the Shannon-Wienner (H ' and Pielou (J' diversity index of 0,88 and 0,85 respectively, showed that the study area exhibits low diversity of species compared to studies in similar forests. The diameter distribution adjusted by the Meyer function showed a deficit of individuals in class 12,5 cm and 17,5 cm as a result of underutilization of individuals of lower diametric class by the local community, however, this is showing good resilience of its structure.
Full Text Available The need to conduct research on the impact of elephant on the environment prompted the construction of exclosures along two of the most important rivers in the Kruger National Park. Scientific research on these exclosures along the Sabie and Letaba rivers addresses how patterns of spatial and temporal heterogeneity of the riparian zone are affected by fire, flood and herbivory. To further assist this research programme, a vegetation survey was conducted at the Nkhuhlu exclosure site along the Sabie River to classify and map the vegetation of the area. This will provide baseline data to assess future changes in vegetation and floristic patterns due to small-scale environmental factors created by the presence/absence of herbivory and fire. Phytosociological data were analysed to identify plant communities and subsequent mapping units. Five plant communities, ten sub-communities and four variants were recognised and described in relation to prevailing soil forms. Differences in species richness, diversity and community structure of the plant communities are clearly articulated.
Full Text Available The objective of this study was to describe the floristics and the structure of tree species in the Parque Municipal Natural of Lages, SC, a remnant of mixed rain forest located in southern Brazil. For this, we allocated four plots (40 x 40m and each plot was divided into 16 sub-plots of 10 x 10m. Trees with dbh ≥ 5cm and height ≥ 1.3m were mapped, tagged and measured. The individuals were identified and voucher material was deposited in the herbarium. A total of 46 species were sampled, distributed in 39 genera and 27 families. The richest families in number of species were Myrtaceae, Lauraceae, Salicaceae and Sapindaceae. Seven species represented more than 60% of the total of individuals. The specific diversity was H’ = 3.05 nats.ind-1 (J’ = 0.81. The similarity among plots was 32 at 44%, indicating low similarity among plots. The spatial distribution of most of the species is classified as clumped, according to the Morisita index. This forest remains with a considerable richness and diversity with some endangered tree species such as Araucaria angustifolia and Dicksonia sellowiana. Due to its ecological importance for the local flora and fauna and the fragmentation process in the region, this remnant should be considered as a priority area for conservation.

A survey of the vascular flora of Yucca Mountain and vicinity, Nye County, Nevada, was conducted from March to June 1994. An annotated checklist of recorded taxa was compiled. Voucher plant specimens were collected and accessioned into the Herbarium at the University of Nevada, Las Vegas. Collection data accompanying these specimens were entered into that herbarium's electronic data base. Combined results from this survey and the works of other investigators reveal the presence of a total of 325 specific and intraspecific taxa within the area, these allocated to 162 genera and 53 families. Owing to drought conditions prevalent throughout the area, the annual floristic component was largely absent during the period of study, and it is likely much under-represented in the tabulation of results. No taxon currently listed as threatened or endangered under the Endangered Species Act was encountered during this study. Several candidate species for listing under this Act were present, and distributional data for these were recorded. No change in the status of these candidate species is recommended as the result of this survey

We used a very large dataset (>40% of all species) from the endemic-rich Cape Floristic Region (CFR) to explore the impact of different weighting techniques, coefficients to calculate similarity among the cells, and clustering approaches on biogeographical regionalisation. The results were used to revise the biogeographical subdivision of the CFR. We show that weighted data (down-weighting widespread species), similarity calculated using Kulczinsky’s second measure, and clustering using UPGMA resulted in the optimal classification. This maximized the number of endemic species, the number of centres recognized, and operational geographic units assigned to centres of endemism (CoEs). We developed a dendrogram branch order cut-off (BOC) method to locate the optimal cut-off points on the dendrogram to define candidate clusters. Kulczinsky’s second measure dendrograms were combined using consensus, identifying areas of conflict which could be due to biotic element overlap or transitional areas. Post-clustering GIS manipulation substantially enhanced the endemic composition and geographic size of candidate CoEs. Although there was broad spatial congruence with previous phytogeographic studies, our techniques allowed for the recovery of additional phytogeographic detail not previously described for the CFR.

We studied the floristic composition and distribution of the riparian forest of two hydrographical systems in a subtropical Andean region. Using uni and multivariate techniques, we tested the hypotheses that a differentiable riparian forest exists, composed by native vegetation typical of the Yungas phytogeographical province, and that the distribution of vegetation varied significantly with geomorphologic characteristics. Parallel transects along the water courses were used to collect presence-absence data of vegetation in eleven sites. Detrended Correspondence Analysis defined a group of common riparian species for the studied area (Solanum riparium, Phenax laevigatus, Tipuana tipu, Cestrum parqui, Carica quercifolia, Acacia macracantha, Celtis iguanaea, Juglans australis, Pisoniella arborescens, Baccharis salicifolia, Cinnamomum porphyrium and Eugenia uniflora) and identified two reference sites. The distribution of the riparian vegetation varied significantly with the geomorphic characteristics along the studied sites. Riparian habitats were composed by native and exotic species. A distinct riparian flora, different in structure and function from adjacent terrestrial vegetation, could not be identified. Riparian species were similar to the adjacent terrestrial strata. These species would not be limited by the proximity to the river. Anthropogenic impacts were important factors regulating the introduction and increase of exotic vegetation. The lack of regulation of some activities in the zone could cause serious problems in the integrity of this ecosystem.

In regularly burned grassland on Morro Santana, Porto Alegre, RS, Brazil, we investigated differences in the floristic composition and their relation to soil properties, aspect and distance from the forest border. In 48 plots of 0.75 m2, we identified a total of 201 species from a local species pool of approximately 450 to 500 species. Most species occurred in low frequencies, showing clumpy distribution patterns in the studied area. Multivariate analysis showed that plots close to the forest edge clearly differed from plots in the open grassland concerning composition and structure. Plots exposed to the north differed from plots on the top of the hill both in the composition of species as well as in soil variables, mainly due to shallower soil in the former. No strong relation between soil properties and variation in vegetation composition could be detected at a finer scale. The studied grassland, as all grassland vegetation in southern Brazil, is very rich in species compared to other grassland formations worldwide. However, this high biodiversity and conservational value of Campos vegetation in general has so far not been recognized properly. Disturbance is essential to maintain this open vegetation type and its species richness. Fire should be considered as a management option in the absence of grazing.

The floristic composition and the structure of a humid hill forest were determined. The forest is located in the northernmost area of the Colombian Central Mountain Range. The methodology proposed by ISA-JAUM was employed in this study, from a 0.1 ha sample. Moreover, plant material was collected from clear spots, stubbles and grasslands. A total of 421 vascular plants species were found. Two hundred and thirty eight of these come from the 0.1 ha sample and only 150 had DBH> 2.5 cm, which highlights the benefits of the sample method employed, since it was possible to record a large number of epiphytic and herbaceous elements in the forest. In general, the composition matches what was previously reported in similar areas. The families Melastomataceae (32), Lauraceae (31), Rubiaceae (29) and Araceae (15) were the ones holding the largest number of species. New chorological records for the state of Antioquia were reported in this study; for instance, Colombobalanus excelsa (Fagaceae). High density of individuals (388) was found at structural level. The patterns of height and diametrical classes followed the typical distribution of disetaneous tropical forests, in which the largest amount of individuals occur in the lowest classes and few species with individuals having the greatest diameters and heights account for the major ecological weight in the forest. Despite the great diversity documented, these forests are currently subject to an intensive process of fragmentation and loss of coverage.
Full Text Available Floristic composition of boxwood (Buxus hyrcana Pojark stands in the forests of Western Haraz, distributed at the altitudinal range of 250 to 1,200 m asl, was investigated by field-walk method. Results showed that the flora of this area includes 50 families, 69 genera, and 78 plant species. Rosaceae, Orchidaceae, Dryopteridaceae, Lamiaceae and Aspleniaceae are the greatest families in this area. Chorological studies showed that the largest proportion of the flora is related to Euro-Siberian region (56.4%. Cryptophytes (32 species, Phanerophytes (26 sp. and Hemicryptophytes (16 sp., which are compromising 44%, 33.3% and 20.5% of the flora, were the most important structure groups of the biological spectrum. Abundance of Cryptophytes with Phanerophytes and Hemicryptophytes in these forests implys that there is a temperate climate with cold winter, frequently rainfall and relatively cool summer, which are suitable for growing temperate forest. Frequent occurrence of Prunus Laurocerasus trees with Daneae racemosa as a woody understory species especially in the upper parts of the studied area accompany by absence of Therophytes and relatively well distribution of ferns species, especially Asplenium scolopendrium, also implys high, favorable, moisture conditions without any disturbances in Box tree stands of these forests.

Full Text Available ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. They are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that differ from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest contain unusually high levels of plant species richness and endemism. This study aimed to inventory species of vascular plants and to describe the main habitat types found on an inselberg located in the state of Minas Gerais, in southeastern Brazil. A total of 89 species of vascular plants were recorded (belonging to 37 families, of which six were new to science. The richest family was Bromeliaceae (10 spp., followed by Cyperaceae (seven spp., Orchidaceae and Poaceae (six spp. each. Life forms were distributed in different proportions between habitats, which suggested distinct microenvironments on the inselberg. In general, habitats under similar environmental stress shared common species and life-form proportions. We argue that floristic inventories are still necessary for the development of conservation strategies and management of the unique vegetation on inselbergs in Brazil.

Full Text Available Vascular epiphytes constitute a life form that is important to maintaining the biological diversity of forest ecosystems, because they provide food resources and specialized microenvironments for fauna in the forest canopy. This study aimed to describe the floristic composition and ecological aspects of vascular epiphytes occurring in the restingas (coastal woodlands within the Algodoal-Maiandeua Environmentally Protected Area, located in the municipality of Maracanã, in the state of Pará, Brazil. We sampled five 50 × 50 m plots (three in dry restinga forest and two in floodplain restinga forest, the sampled area therefore totaling 1.25 ha. In the plots sampled, vascular epiphytes were identified and described according to their frequency, abundance, importance value (IV, functional group and vertical distribution (trunk, lower crown or upper crown of the host. For both forest types, we identified 477 individuals belonging to five families, nine genera and 11 species. The most species-rich families were Araceae and Orchidaceae. The species with the highest density, frequency and IV were the secondary hemiepiphytes Philodendron acutatum, Anthurium pentaphyllum and Philodendron muricatum, collectively accounting for 92.1% of all sampled individuals. The true epiphytes predominated. Epiphytic species richness and abundance was greater on the host trunk than in the lower or upper crown. The seasonal climate and structure of the forest favored greater abundance of secondary hemiepiphytes and a higher frequency of epiphytes on the trunks of their hosts.
Global Mindsets: Exploration and Perspectives seeks to tackle a topic that is relatively new in research and practice, and is considered by many to be critical for firms seeking to conduct global business. It argues that multiple mindsets exist (across and within organizations), that they operate...... in a global context, and that they are dynamic and undergo change and action. Part of the mindset(s) may depend upon place, situation and context where individuals and organizations operate. The book will examine the notion of "mindset" is situational and dynamic, especially in a global setting, why...... it is important for future scholars and managers and how it could be conceptualized. Global Mindsets: Exploration and Perspectives is split into two major sections; the first examines where the literature currently is with respect to the knowledge in the field and what conceptual frameworks guide the thinking...

In today’s world, change is faster than ever with rapid technological development and increasing global competition. The effects of globalization have led to more intense international competition when competitors originate from different parts of the world. Thanks to the use of new information technology, transparency has increased and made it possible for customers to compare products and prices between suppliers and prices in different markets and also buy cross-border. This puts pressure ...

Highlights: • Place is a central yet undertheorised concept within sustainability science. • Introduces an account of place as the context in which social and environmental mechanisms operate. • Uses this account to critique historical aspatial approaches to climate science and policy. • Traces out shifts towards spatially explicit approaches to climate governance. • A focus on place, heterogeneity, and context maximizes the credibility and policy-relevance of climate science. - Abstract: Place is a central concept within the sustainability sciences, yet it remains somewhat undertheorised, and its relationship to generalisation and scale is unclear. Here, we develop a mechanistic account of place as the fundamental context in which social and environmental mechanisms operate. It is premised on the view that the social and environmental sciences are typically concerned with causal processes and their interaction with context, rather than with a search for laws. We deploy our mechanistic account to critique the neglect of place that characterised the early stages of climate governance, ranging from the highly idealised general circulation and integrated assessment models used to analyze climate change, to the global institutions and technologies designed to manage it. We implicate this neglect of place in the limited progress in tackling climate change in both public and policy spheres, before tracing out recent shifts towards more spatially explicit approaches to climate change science and policy-making. These shifts reflect a move towards an ontology which acknowledges that even where causal drivers are in a sense global in nature (e.g. atmospheric levels of greenhouse gases), their impacts are often mediated through variables that are spatially clustered at multiple scales, moderated by contextual features of the local environment, and interact with the presence of other (localised) stressors in synergistic rather than additive ways. We conclude that a

Vicariance and dispersal are two important processes shaping biodiversity patterns. The South African Cape Floristic Region (CFR) is known for its high biotic diversity and endemism. However, studies on the phylogeography of endemic invertebrates in this biodiversity hotspot are still scarce. Here, we present a phylogenetic study of the flightless grasshopper genus Betiscoides, which is endemic to the CFR and strongly associated with restio plants (Restionaceae). We hypothesized that the genus originated in the southwestern part of the CFR, that differentiation within the genus is mainly an effect of vicariance and that the three known species only represent a minor fraction of the real genetic diversity of the genus. We inferred the phylogeny based on sequences of three mitochondrial and two nuclear genes from 99 Betiscoides specimens collected across the CFR. Furthermore, we conducted a SDIVA analysis to detect distributions of ancestral nodes and the possible spatial origin of these lineages. Strong differentiation among genetic lineages was shown. The ancestor of this genus was most likely distributed in the southwestern CFR. Five major lineages were detected, three of which were ancestrally distributed in the southwestern CFR. The ancestors of the two other lineages were distributed in the northern and eastern margins of the CFR. A total of 24 divergent evolutionary lineages were found, reflecting the geographical isolation of restio-dominated fynbos habitats. Dispersal played a more prominent role than expected in differentiation of Betiscoides. While the five main lineages were separated during a first phase via dispersal, differentiation occurred later and on smaller spatial scale, predominantly driven by isolation in montane refugia (i.e. vicariance). Our study also suggests that flightless insect taxa likely show high levels of differentiation in biodiversity hotspots with their taxonomy often being incomplete. Copyright © 2017 Elsevier Inc.

Excessive soil nutrients, often from agricultural runoff, have been shown to negatively impact some aspects of wetland plant communities. We measured plant-available phosphorus (Mehlich-3: MeP) in soil samples, and assessed the vascular plant community and habitat degradation at 27 emergent and 13 forested wetlands in Ohio, USA. We tested two hypotheses: (1) that an index of vegetation biological integrity based on floristic quality was lower in wetlands with higher concentrations of MeP in the soil, and (2) that higher concentrations of MeP occurred in wetlands with more habitat degradation (i.e., lower quality), as estimated by a rapid assessment method. Hypothesis (1) was supported for emergent, but not for forested wetlands. Hypothesis (2) was marginally supported (P=0.09) for emergent, but not supported for forested wetlands. The results indicate that the effect of concentration of phosphorus in wetland soils and the quality of plant species assemblages in wetlands is more complex than shown in site-specific studies and may depend in part on degree of disturbance in the surrounding watershed and dominant wetland vegetation type. Woody plants in forested wetlands are typically longer lived than herbaceous species in the understory and emergent wetlands, and may persist despite high inputs of phosphorus. Further, the forested wetlands were typically surrounded by a wide band of forest vegetation, which may provide a barrier against sedimentation and the associated phosphorus inputs to the wetland interior. Our results indicate that inferences about soil nutrient conditions made from rapid assessment methods for assessing wetland habitat condition may not be reliable. Copyright © 2016.

Full Text Available Most forests in the tropics have not only been reduced in size but have also experienced forest degradation. The delicate balance of the components of the forest ecosystem has been altered largely by the landuse systems which have resulted in the disappearance of some species and the introduction of new ones. In order to understand the influence of human disturbance caused by artisanal mining on plant biodiversity and the physical environment, this study assessed changes in vegetation characteristics using plant functional groups, such as invasive, pioneer and understory species. The study was conducted at two sites in two Southwestern states of Nigeria, Itagunmodi in Atakumosa West Local Government Area of Osun State and Olode in Oluyole Local Government Area of Oyo State. Complete enumerations of woody, non-woody and herbaceous plant species were carried out in 20 m by 20 m plots selected using stratified random sampling as representative of landuse classes: freshly mined (6 months and a control plot (secondary forest. The results showed that the control plot in Itagunmodi had undergone degradation as indicated by the presence of Alchornea laxiflora, Geophilia obvallata, Musa sapientum,Elaeis guineensis and Keetia hispida. However, if left undisturbed, it has the potential of regeneration back to its original state because of its woody tree species composition and lianas (Triclisia gilletii. In addition the forest soils in the mines had been exposed to direct insolation for a long period, and the soil structure and texture have been affected, consequently altering the viability of the seed bank. Poaceae and Papilionoideae were the most common in the freshly mined plots while invasive species were the most common in abandoned mined plots. In conclusion, the floristic composition in the mining sites has been altered and there was no clear evidence that regrowth would bring restoration of the lost ecosystem services.
Full Text Available The effect of fertilization and the harvest frequency on production and floristic characteristics of a meadow stand were assessed in a small plot trial established in 2003 in Vatín, Vysočina Region, the Czech Republic. Four levels of fertilization (none; N0 + P30 + K60 kg∙ha−1; N90 + P30 + K60 kg∙ha−1; N180 + P30 + K60 kg∙ha−1 were combined with four treatments of exploitation intensity (4 cuts per year, first cut on 15th May, every next after 45 days; 3 cuts per year, first cut on 30th May, every next after 60 days; 2 cuts per year, first cut on 15th June, next after 90 days; 2 cuts per year, first cut on 30th June, next after 90 days. Production of dry matter and proportions of guilds (grasses, legumes, and other species were evaluated. Data from 2009–2011 were used in this paper. Yields of the dry matter increased along with increasing amounts of nutrients supplied and ranged from 3.8 t∙ha−1 (non-fertilized to 9.1 t∙ha−1 (N180PK. The nutrition level had a significant effect on spread of grasses, which reached maximal proportion of 52.3 % under N180PK fertilization compared to 42.1% on non-fertilized plots. On the contrary, legumes flourished well in treatments without N-supply, attaining proportion of 6.8 % and 5.1 % on PK-fertilized and non-fertilized plot, respectively. With regard to the exploitation intensity grasses profited from extensive management by contrast to the group of other species which reached its maximum in swards harvested four times a year. Proportions of legumes did not show significant dependence on the cutting frequency.
Full Text Available Cliffs are among the environments with the most adverse conditions for living organisms because of the limited availability of soil, moisture, and nutrients, and owing to the harsh conditions of exposure. They constitute shelters for rare, endemic, and range-restricted plant taxa. A main database has been prepared which includes vascular plant taxa that are obligate or facultative chasmophytes and also contains information about their life form, chorology, protection status, occurrence in more than 135 places such as cliffs, gorges, or open rocky habitats, and their geographical distribution in the 13 phytogeographical regions of Greece based on available floristic, vegetation, and phytosociological literature and on the authors' own collections and observations. The paper presents an analysis of the total diversity of cliff plant species, as well as the diversity of obligate chasmophytic plant species, endemics, and range-restricted taxa, in addition to the results of studying the distribution patterns of different subsets of plant taxa in the different phytogeographical regions of Greece. Hemicryptophytes and chamaephytes are the dominant life forms of the chasmophytic taxa. Among 935 species and subspecies registered, 476 are obligate chasmophytes, of which the majority are Greek endemics. Hierarchical cluster analysis of different subsets of plant taxa revealed affinities of the cliff flora of different phytogeographical regions. Additionally, 15 chasmophytic taxa mentioned in Annexes II, IV, and V of EEC Directive 92/43 belong to the cliff flora, of which 10 are obligate chasmophytes and nine have a priority for protection. Eighteen taxa are included in the IUCN Red List of Threatened Species, of which four are critically endangered (CR, seven are vulnerable (VU, and three are endangered (EN. The distinct correlation between endemism and chasmophytic ecology is emphasized, since a detailed understanding of the local distribution and
Background and aims The florist's gloxinia is a familiar houseplant in the Gesneriaceae, the botanical family that includes the African violet (Saintpaulia) and other ornamental species. The gloxinia's wild progenitor is Sinningia speciosa (Lodd.) Hiern, a Brazilian endemic. Although it has been cultivated for almost 200 years, little is known about the genetic diversity in S. speciosa, how the wild populations relate to one another or even where the cultivated forms originated. Using available wild collections, preliminary phenetic and phylogenetic investigations were conducted to elucidate the interspecific relationships within S. speciosa and to infer the origins of the cultivars. Methodology Amplified fragment length polymorphism (AFLP) analysis was applied to 24 accessions of S. speciosa (17 wild collections, seven cultivars) and one accession each of Sinningia guttata and Sinningia macrophylla. A maximum likelihood (ML) tree was also calculated from an alignment of the nuclear ribosomal internal transcribed spacer sequence from the same 26 accessions. Principal results Dice/UPGMA and principal coordinates analysis of the AFLP data partitioned S. speciosa into several distinct clusters, one of which included S. macrophylla. All cultivated ‘gloxinias’ grouped together in a major cluster with plants from Rio de Janeiro. The AFLP results were compared with a phylogenetic analysis of the ribosomal spacer region, which was informative in S. speciosa. The ML tree generally supported the AFLP results, although several clades lacked strong statistical support. Conclusions Independent analyses of two different data sets show that S. speciosa is a diverse species comprised of several lineages. Genetic distance estimates calculated from the AFLP data were positively correlated with geographic distances between populations, indicating that reproductive isolation could be driving speciation in this taxon. Molecular markers are under development for population genetic

To determine the present status of plant communities and their possible association with the habitat in Malam Jabba, Swat, Pakistan. A study on the phytoecology was conducted in various ecologically important sites of Malam Jabba, Swat, Pakistan from 2002 to 2004. The altitude of these sites ranged from 1 200 m to 3 200 m. Quadrat method was used for evaluation of plants communities and the data on these attributes was converted to relative values. The plant communities were named after 3 leading species with highest importance values. Biological spectrum of the flora based on the life form was prepared by following Raunkiar's life form classes. The floristic composition and structure of the study area were found to be 200 species belonging to 75 families. Asteraceae, Lamiaceae and Poaceae were important families in the study area. The biological spectrum showed that therophytic and hemicrytophytic life form and micro-nonophyllous leaf sizes were dominant in the area. The air and soil temperatures were decreasing with increasing elevation. Both the air and soil temperatures were relatively higher in south slopes than on the northeast slopes. The vegetation analysis of the area indicated eleven plant communities around the area. The present vegetation is the relics of moist temperate coniferous forest in the area. The communities reflect highly deteriorated conditions. Both the structure and composition of the surrounding vegetation were associated with the types of habitats. The conservation of the remaining populations of the reported communities will be best achieved by proper time of sustainable harvesting. It is only possible with the participation of local communities.

Full Text Available ABSTRACT Knowledge of weed floristic composition and phytosociology are key factors for improving weed management in pastures. Information on weed species that occur in pastures in Northeast Brazil, particularly in Maranhão State is very limited. It is, therefore, important, to search for information to help farmers to control weeds in livestock farming. This paper describes the weed flora diversity and community structure parameters, including density, frequency, abundance and importance value for each weed species found in five pastures of same age and management in Maranhão State, Northeast Brazil. The weed survey was carried out using a wooden frame (80 cm x 30 cm placed randomly on the soil surface 30 times in each pasture (n = 150. Weeds were pulled out, separated by species and counted. The weed flora was represented by 996 individuals, from nine families, 15 genera and 19 species. Weed density within pastures was of 44.3 plants m-2. The weed flora was dominated by species of the Cyperaceae and Poaceae families. The most important weed species based on Importance Value were Eragrostis ciliaris (IV = 32.97, Cyperus rotundus (IV = 31,95, Cyperus luzulae (IV = 27,50, Cyperus sphacelatus (IV = 27,42, Pycreus lanceolatus (IV = 27,33 Cyperus haspan (IV = 25,72 and Eleusine indica (IV = 23,49. Weed diversity, based on Shannon Diversity Index was very high (H' = 4.37 nats ind-1. Our results could lead to improved weed management in pastures in Maranhão State, Northeast Brazil.

Full Text Available The mining activities cause intense environmental degradation, especially to the soil and vegetation. This study evaluated attributes of floristic composition and soil fertility in areas of open gold mining areas. One hundred plots of 10 × 10 m were distributed in the area effectively mined and in its surroundings. Stem circunference measures (AGC of all identified woody individuals with greater than or equal to 9 cm were taken at 0.3 m height above the ground. In all plots soil samples at 0-20 cm depth were collected for analysis of fertility attributes that are routinely evaluated. In total we observed the occurrence of 92 species and 43 families. The most abundant families were Myrtaceae, Fabaceae and Dilleniaceae; and families that had the greatest numbers of species were Fabaceae (10, Malpighiaceae (7 and Vochysiaceae (5. In the area effectively mined the species with higher importance value index (IVI were Curatella americana (89.1 Cecropia hololeuca (40.9, Roupala montana (12.5 and Pouteria ramiflora (10.2 while in surrounding of the mined area the species with the highest IVI were Myrcia multiflora (25.6, Caryocar brasiliense (15.7, Magonia pubescens (14.8 and Vatareia macrocarpa (14.4. In both areas, the soil had low pH, low availability of P, K+, Ca2+ and Mg2+ and high Al3+ saturation. In spite of the low soil fertility of the studied area, it was able to maintain an overall density of vegetation with AGC > 9 cm of 430 individuals per hectare in the effectively mined area and of 2,220 individuals per hectare in their surroundings.

Detailed field survey was carried out to assess the floristic composition, phenology, leaf and biological spectrum of Tehsil Havelian during 2011-2012. A total of 205 plant species belonging to 78 families were documented. According to plant habit there are 129 species of herbs, 38 species of trees and 38 species of shrubs. Asteraceae and Lamiaceae were dominant families with 15 species each, then Brassicaceae 11 species, Rosaceae and Papilionaceae with 10 species each. They were followed by Ranunculaceae with 9 species. All the remaining 72 families have less than 7 members. Flowering season was classified in two spells, first from March to July with 62.56% herbs, 19.48% shrubs, 18.46% trees, 2.56% grasses and 1.02% ferns. Second spell starts from August to November with 50% shrubs, 30% herbs and 20% trees. The life form classes were determined by the Raunkier's method which reveals that the most dominant life form was Therophytes with 89 species (43.68%), followed by Nanophanerophytes 26 species (12.62%), Megaphanerophytes 20 species (9.70%), Mesophanerophytes 19 species (9.22%), Chamaephytes 15 species (7.28%), Hemicryptophytes 15 species (7.28%), Geophytes 11 species (5.33%), Lianas 6 species (2.91%), Microphanerophytes 3 species (1.45%) and Neophytes with 1 species (0.48%). As for as leaf size concerned, Microphyll was the most prevalent leaf size with 98 species (47.80%), followed by Nanophyll 55 spp. (26.82%), Leptophyll 28 species (13.65%), Mesophyll 16 spp. (7.80%) and Megaphyll contributing with 8 species (3.90%). Study reflects the overall ecological scenario and may be beneficial as reference study for conservation and sustainable use of plants. (author)
Full Text Available This work aimed at knowing and evaluating the florisitc composition, the strucuture and the diversity of the regenerating species in a gully at Itumirim, MG. The gully possesses an area of 0.9 ha and was subdivided into three sectors named as arms “A”; “B” and “C”. For the structural survey of the vegetation the needle method was employed, i. e. , 574 points distributed systematically across the three arms were sampled. Each spot was stratified on the terrain as related to a topographic gradient. The indicator species analysis (ISA was used to give statistical support to the standards found. A florisitic survey was also conducted with the purpose of recording all the species of shrub-tree life form ocorring in the gully. Through the strucutural survey, it was found that the species of the group of “grass-like” and “ferns” dominated widely all the sectors. The indicator species analysis performed for each of the arms pointed out that Ludwigia elegans (Cambess. H. Hara presents high fidelity, and, therefore, can be regarded as an indicator of the sector slack for arm “A” (p = 0.002.the group of species which make up the guild “ferns” was considered an indicator for the upper third of arm “C” (p = 0.038. In the floristic survey concerning the species of shrub-tree life form, 73 species were recorded in the three arms arms 73, distributed into 63 genera and 33 botanic families. The families with highest diversities of species were Fabaceae, Asteraceae, Melastomataceae and Myrtaceae, standing for 46.6% of the total of recorded species.

Full Text Available The objective of the study was to evaluate diversity and floristic similarity of Cerrado environments, under different levels of anthropization for agricultural usage and extractivism, and to generate a database to subsidize sustainable development proposals for the North region of Minas Gerais State, and traditional agriculture systems. Four areas with different levels of anthropization were sampled, in the following environments: “Areião, Areiãozinho, Chapada de Latossolo and Tabuleiro”, whose identifications had been made from key informers in the Água Boa Community, in Rio Pardo de Minas (MG, Brazil. The sampled units were distributed in 8 parcels of 20 x 50 m, with 5 subplots. The trees with circumference at ground level of 15 cm or bigger were measured. For analysis of the phytosociology indexes the following parameters were calculated for each environment: density, dominance, frequency, basal area, and importance value. For the floristic diversity the Shannon (H' was calculated, and for the analysis of similarity the index of Jaccard index (Sij. In all the environments, it was found a total of 477 individuals, distributed in 21 families, with 48 botanical species identified, and 27 individuals not identified. The five most important (importance value families was Fabaceae/Papilionoideae, Apocynaceae, Vochysiaceae, Sapotaceae and Fabaceae/Caesalpinoideae. And the ten most important species was Pouteria ramiflora, Dalbergia miscolobium, Hancornia speciosa, Macherium opacum, Sclerolobium paniculatum var. subvelutinum, Qualea grandiflora, Aspidosperma tomentosum, Byrsonima pachyphylla, Vochysia thyrsoidea and Hymenaea stigonocarpa. The H' index was of 3.01; 2.72; 2.48 and 2.09 for “Areião, Areiãozinho, Chapada de Latossolo and Tabuleiro”, respectively. The Sij index indicated a small floristic similarity for all the combinations between the environments.

Full Text Available Objective: To analyze floristic compositions, biological spectrum and conservation status of the existing vegetation in valley. Methods: A quantitative phytosociological survey was conducted using quadrat method at different sites. Sampling was done by using quadrat method. A complete floristic list of the plant communities of the study area was compiled on the basis of plant collection. Life form and leaf spectra were constructed using the complete list of the plant communities collected from study area. Conservation status of each species was established on the basis of International Union for Conservation of Nature criteria. Results: The flora of Nikyal valley consisted of 110 species belonging to 51 families and 98 genera. Poaceae (18 spp., Asteraceae (10 spp., Lamiaceae (8 spp. and Fabaceae (7 spp. were the leading families in the area. Biological spectrums of 13 different plant communities were grouped into four plant associations on the basis of cluster analysis and detrended correspondence analysis. The data showed that hemicryptophytes (32.73% were the dominant life form in the area followed by therophytes (23.64% and nanophanerophytes (22.73% during monsoon season. Similarly, nanophyllous species (37.27% followed by microphyllous species (29.09% remained dominant during monsoon in the investigated area. Conclusions: The majority of important plant species of Nikyal valley are critically endangered, therefore effective measures for conservation of plant resources of the valley are urgently needed. We recommend the floristic life-form spectrum technique if working in sufficiently large areas, because it could provide an indication of the prevailing phytoclimate.

Full Text Available Many species extinctions have probably gone unnoticed on limestone that was destroyed before they could be sampled. Unless biodiversity surveys are intensified, the true magnitude of extinctions will never be ascertained. The objectives of this study were to determine tree species composition of limestone hills in Nyungcung and Ciampea; to determine quantitatively the dominant and less dominant species and to quantify floristic structure of the two limestone hills. Value of richness (Menhinick and evenness in Nyungcung were 3.28 and 0.826 whilst in Ciampea were 3.29 and 0.823, respectively. In term of diversity (Shannon Wiener, Nyungcung seems to be more diverse than Ciampea as indicated by the higher value of diversity index. Nyungcung has 3.225 of diversity (Shannon Wiener index while Ciampea has 2.859. The floristic composition of two sites was significantly different and mostly comprised Moraceae, Rubiaceae, and Euphorbiaceae. However, the highest presence of species were Antidesma montanum (Euphorbiaceae and Chrysophyllum lanceolatum (Sapotaceae, and Pandanus sp.

Full Text Available ABSTRACT Only a few studies regarding vascular epiphytes have been conducted in mixed ombrophilous forests (MOF in Serra da Mantiqueira, a mountainous environment in the Brazilian Atlantic Forest, where the relationships of epiphytic flora with other physiognomies are unknown. This study aimed to survey the epiphytes of a MOF remnant located in Serra da Mantiqueira, and to analyze the floristic relationships with ombrophilous forests of the Southern and Southeastern regions of Brazil. The checklist was compared with 51 other areas composed of ombrophilous forests and/or ecotones with other physiognomies using UPGMA (with Sørensen index, and canonical correspondence analysis (CCA. We recorded 138 species, and Orchidaceae and Polypodiaceae were the richest families (51 and 23 species, respectively. The UPGMA showed the importance of physiognomy and elevation in the floristic relationships, and CCA reinforced the influence of elevation, in addition to the shortest distance to the ocean and minimum annual temperature; however, in this analysis, the physiognomies showed little influence on the relationships. The epiphytic flora of MOF of Southern and Southeastern regions of Brazil has different relationships compared with the data available for shrubs and trees, suggesting a greater importance of phorophytic species than geographical distance and, to some extent, environmental variables.

We aimed to investigate the taxonomic and functional variations of tree component of Araucaria Forest (AF) areas located along an altitudinal gradient (700, 900 and 1,600 m asl), in the southern region of Brazil. The functional traits determined were leaf area, specific leaf area, wood density, maximum potential height and dispersal syndromes and deciduousness. The data were analyzed through a functional and taxonomic dissimilarity dendrograms, community-weighted mean trait values, parametric and nonparametric tests, and Principal Component Analysis. The largest floristic-structural similarity was observed between the lower altitude areas (700 and 900 m asl), whose Bray-Curtis distance was 0.63. The area at 700 m asl was characterized by a predominance of deciduous and semi-deciduous species, with a high number of self- and wind-dispersed species, whereas the area at 1,600 m asl exhibited a predominance of animal-dispersed and evergreen species. It was also observed that there were significant variations for leaf traits, basic wood density and maximum potential height. Over all altitudinal gradient, the ordinations indicated that there was no evidence of functional differentiation among dispersal and deciduousness groups. In conclusion, the evaluated Araucaria Forest areas presented high floristic-functional variation of the tree component along the altitudinal gradient.
The Floristic and structural characterization of the main forest types in the Taraira Sierra, it was carried out to give to know the forests that exist there, since there were not preliminary studies on this ecosystem, and to enlarge the knowledge on the forests of the Colombian Guayana. For the composition study and it structures of the vegetation, three parcels of study of 0.05 hectares settled down, 10m x 50m each one; two in high Catinga and one in the Arbustiva; likewise they were traveled by different places of the Sierra to collect vegetable material. According to the floristic composition, to the covering analysis, and to the Sorensen index (Cordoba, 1995) they were defined three communities, the first of them in Catinga arbustiva, Clusia spathulaefolia - Retiniphyllum truncatum that is characterized to reach heights until of 10 meters, on sandy soils with inferior slope to 7%. In the high Catinga they were two communities, Micrandra sprucei - amazon Poecilanthe and Micrandra sprucei - Tovomita clarkii, which are characterized to present a superior stratum that reaches the 20 meters high. The Taraira Sierra, makes part of the high-priority of conservation areas due to its wealth of species as much animals as vegetables, to its high endemism that is developed on poor and fragile soils of the Guianese shield and to that this ecosystem is in risk, due to the mining exploitation

In this study, 19 sites representing different habitats in Hail region were regularly visited for two years, in each site 2-5 stands were selected for investigating floristic composition and vegetation types in the area. A total of 124 species representing 34 families were recorded. The family Asteraceae is represented by the highest number of species (21 species) followed by the Poaceae (17 species) and the Brassicaceae (10 species) whereas, 15 families including Acanthaceae, Convolvulaceae, Moraceae, Nyctaginaceae and Primulaceae, are represented by a single species each. Chronological analysis of the vegetation in the area revealed the domination of Saharo-Sindian elements in the wild vegetations and of weedy species in the cultivated plots. Therophytes and chamaephytes are the dominating life forms of the vegetation spectra; therophytes represent 49.20% and chamaephytes represent 29.00% of the total species in the study area. Application of TWINISPAN and DECORANA classification and ordination techniques to the data produced seven vegetation groups. Ruderal habitats comprised two small groups A and F dominated by Phragmites australis and Imperata cylindrical (A), Euphorbia peplus and Sisymbrium irio (F), respectively. Two vegetation groups (B and G) have been recognized in the mountains and slopes dominated by Launaea mucronata, Trigonella stellata (B) and Ficus palmate and Fagonia bruguieri (G). Other two groups (C and E) inhabit the desert and mountainous wadies; these are represented by Gymnocarpos decandrus and Ochradenus baccatus (C) and Senecio glaucus subsp. coronopifolius and Rumex equisetiforme (E). On the other hand, one group (D) inhabits the cultivated plots and is represented by Plantago albicans and Rumex vesicarius, the last group also includes species restricted to the sand dune habitat of the Al-Nafud desert north of Hail city and represented by Calligonum polygonoides and Halyxolon salicornicum.

Extending research on self-other differences in perception to a global health risk, this study compares U.S. and Chinese college students' perceived H1N1 flu risk at four levels: personal, group, societal, and global. It also examines how personal experience, interpersonal communication, traditional and Internet-based media, and self-efficacy affect perception at four levels, as well as the self-other differences between the personal level and each of the other three levels. An online survey in both countries reveals an "ascending pattern," showing higher perceived risk for others than for selves. Chinese respondents perceive higher risk than U.S. respondents at all levels. Interpersonal communication predicts risk perception at four levels in the United States and at the group and societal levels in China. New media exposure exerts influence on all but the group level in China, while social networking sites (SNS) exposure predicts group- and societal-level risk perception in the United States. The overall attention paid to H1N1 information in the media affects all levels in both countries. Interaction between media exposure and attention is influential at all levels in the United States. Self-efficacy is negatively associated with risk perception in China except at the global level. Attention to media in the United States, and SNS exposure in China, explain the self-other differences in three comparisons, along with self-efficacy, which decreases the self-other gap in the United States while increasing the gap in China.

Global financing for the HIV response has reached unprecedented levels in recent years. Over US$10 billion were mobilized in 2007, an effort credited with saving the lives of millions of people living with HIV (PLHIV). A relatively unexamined aspect of the global HIV response is the role of the private sector in financing HIV/AIDS services. As the nature of the response evolves from emergency relief to long-term sustainability, understanding current and potential contributions from the private sector is critical. This paper examines trends in private sector financing, management and resource consumption related to HIV/AIDS in five sub-Saharan African countries, with a particular emphasis on the effects of recently scaled-up donor funding on private sector contributions. We analysed National Health Accounts HIV/AIDS subaccount data for Kenya, Malawi, Rwanda, Tanzania and Zambia between 2002 and 2006. HIV subaccounts provide comparable data on the flow of HIV/AIDS funding from source to use. Findings indicate that private sector contributions decreased in all countries except Tanzania. With regards to managing HIV/AIDS funds, non-governmental organizations are increasingly controlling the largest share of resources relative to other stakeholders, whereas private for-profit entities are managing fewer HIV/AIDS resources since the donor influx. The majority of HIV/AIDS funds were spent in the public sector, although a considerable amount was spent at private facilities, largely fuelled by out-of-pocket (OOP) payments. On the whole, OOP spending by PLHIV decreased over the 4-year period, with the exception of Malawi, demonstrating that PLHIV have increased access to free or subsidized HIV/AIDS services. Our findings suggest that the influx of donor funding has led to decreased private contributions for HIV/AIDS. The reduction in private sector investment and engagement raises concerns about the sustainability of HIV/AIDS programmes over the long term, particularly in

It illustrates the consequences of financial problems of foreign strategic shareholders in banks operating in Poland upon the stability of the entire banking system. It presents the proposed future directions of action to protect the stability of the banking system. It seems that in the case of a banking system as special as the Polish one, the key role will belong to the quality of the three main pillars of control over the work of banks: supervisory institutions, market discipline an corporate governance.

The current study utilizes Skinner's framework to examine the unique contributions of internal locus of control, self-efficacy, and perceived outcome control over course performance on students' academic experiences. Undergraduate students (N = 225) took part in a longitudinal study and completed two surveys (Time 1: just before their mid-term exams; Time 2: just before their final exam in the same semester). Both locus of control and self-efficacy at Time 1 predicted course-level perceived control over course performance at Time 2. Student-level perceived control over course performance at Time 2 mediated the relationship between self-efficacy at Time 1 and course-level perseverance, course-specific stress, and course enjoyment at Time 2. For global perceived stress and life satisfaction measured at Time 2, both locus of control and self-efficacy at Time 1 had only a direct effect on global perceived stress at Time 2, but only self-efficacy at Time 1 predicted life satisfaction at Time 2. Both locus of control and self-efficacy uniquely contribute to students' academic experiences. Student-level perceived control plays an important mediating role between locus of control and self-efficacy at Time 1, and course-level perseverance, course-specific stress, and course enjoyment at Time 2.

In two experiments, we used an effective new method for experimentally manipulating local and global contexts to examine context-dependent recall. The method included video-recorded scenes of real environments, with target words superimposed over the scenes. In Experiment 1, we used a within-subjects manipulation of video contexts and compared the effects of reinstatement of a global context (15 words per context) with effects of less overloaded context cues (1 and 3 words per context) on recall. The size of the reinstatement effects in Experiment 1 show how potently video contexts can cue recall. A strong effect of cue overload was also found; reinstatement effects were smaller, but still quite robust, in the 15 words per context condition. The powerful reinstatement effect was replicated for local contexts in Experiment 2, which included a no-contexts-reinstated group, a control condition used to determine whether reinstatement of half of the cues caused biased output interference for uncued targets. The video context method is a potent way to investigate context-dependent memory.

The majority of emissions scenarios that limit warming to 2°C, and nearly all emission scenarios that do not exceed 1.5°C warming by the year 2100 require artificial removal of CO2 from the atmosphere. Carbon dioxide removal (CDR) technologies in these scenarios are required to offset emissions from sectors that are difficult or costly to decarbonize and to generate global `net negative' emissions, allowing to compensate for earlier emissions and to meet long-term climate stabilization targets after overshoot. Only a few studies have explored the Earth system response to CDR and large uncertainties exist regarding the effect of CDR on the carbon cycle and its effectiveness in reversing climate impacts after overshoot. Here we explore the effectiveness of CDR in lowering atmospheric CO2 ("carbon cycle effectiveness") and cool global climate ("cooling effectiveness"). We force the University of Victoria Earth System Climate Model, a model of intermediate complexity, with a set of negative CO2 emissions pulses of different magnitude and applied from different background atmospheric CO2 concentrations. We find the carbon cycle effectiveness of CDR - defined as the change in atmospheric CO2 per unit CO2 removed - decreases with the amount of CO2 removed from the atmosphere and increases at higher background CO2 concentrations from which CDR is applied due to nonlinear responses of carbon sinks to CO2 and climate. The cooling effectiveness - defined as the change in global mean surface air temperature per unit CO2 removed - on the other hand, is largely insensitive to the amount of CO2 removed, but decreases if CDR is applied at higher atmospheric CO2 concentrations, due to the logarithmic relationship between atmospheric CO2 and radiative forcing. Based on our results we conclude that CDR is more effective in restoring a lower atmospheric CO2 concentration and reversing impacts directly linked to CO2 at lower levels of overshoot. CDR's effectiveness in restoring a

Global health organizations frequently set disease-specific targets with the goal of eliciting adoption at the national-level; consideration of the influence of target setting on national policies, programme and health budgets is of benefit to those setting targets and those intended to respond. In 2014, the Joint United Nations Programme on HIV/AIDS set 'ambitious' treatment targets for country adoption: 90% of HIV-positive persons should know their status; 90% of those on treatment; 90% of those achieving viral suppression. Using case studies from Ghana and Uganda, we explore how the target and its associated policy content have been adopted at the national level. That is whether adoption is in rhetoric only or supported by programme, policy or budgetary changes. We review 23 (14 from Ghana, 9 from Uganda) national policy, operational and strategic documents for the HIV response and assess commitments to '90-90-90'. In-person semi-structured interviews were conducted with purposively sampled key informants (17 in Ghana, 20 in Uganda) involved in programme-planning and resource allocation within HIV to gain insight into factors facilitating adoption of 90-90-90. Interviews were transcribed and analysed thematically, inductively and deductively, guided by pre-existing policy theories, including Dolowitz and Marsh's policy transfer framework to describe features of the transfer and the Global Health Advocacy and Policy Project framework to explain observations. Regardless of notable resource constraints, transfer of the 90-90-90 targets was evident beyond rhetoric with substantial shifts in policy and programme activities. In both countries, there was evidence of attempts to minimize resource constraints by seeking programme efficiencies, prioritization of programme activities and devising domestic financing mechanisms; however, significant resource gaps persist. An effective health network, comprised of global and local actors, mediated the adoption and adaptation

This study estimates the effect of environmental parameters on the mobility of four inorganic contaminants (As, Zn, Pb and Cd) in soils from three areas in the Ebro and Meuse River basins, within the context of global change. An experimental method, applicable to various soil systems, is used to measure the effect of four global-change-sensitive parameters (temperature, gas phase composition, pH and microbial activity). The aqueous phase of batch incubations was sampled regularly to monitor toxic element concentrations in water. Statistical processing enabled discrimination of the most relevant variations in dissolved concentrations measured at different incubation times and under different experimental conditions. Gas phase composition was identified as the most sensitive parameter for toxic element solubilization. This study confirms that total soil concentrations of inorganic pollutants are irrelevant when assessing the hazard for ecosystems or water resource quality. - An experimental method applicable for different soil systems enables the determination of the effect of environmental parameters, potentially affected by global change, on the mobilization of inorganic pollutants.

Driven by insight for which new research and education requires new institutional organisation, and drawing on two decades of research and educational efforts, we devise the profile and activities of a new bioeconomy and solar energy institute at Italy's Research Council. We further articulate the institute's activities suggesting avenues on how to deploy sound and giving more useful research, education and policy advice in these crucial fields for making tomorrow's common development sustainable. The outcomes of the study are of general interest, because the transition to a solar economy is of intrinsic global nature and the challenges involved are similar in many countries. © 2017 Wiley-VCH Verlag GmbH & Co.

Hunger knows no boundaries or borders. While much research has focused on undernutrition on a national scale, this report evaluates it at subnational levels for Sub-Saharan Africa (SSA) to pinpoint hotspots where the greatest challenges exist. Undernutrition is assessed with a spatial resolution of 30 arc-minutes by investigating anthropometric data on weight and length of individuals. The impact of climate change on production of six major crops (cassava, maize, wheat, sorghum, rice and millet) is analyzed with a GIS-based Environmental Policy Integrated Climate (GEPIC) model with the same spatial resolution. Future hotspots of hunger are projected in the context of the anticipated climate, social, economic, and bio-physical changes. The results show that some regions in northern and southwestern Nigeria, Sudan and Angola with a currently high number of people with undernutrition might be able to improve their food security situation mainly through increasing purchasing power. In the near future, regions located in Ethiopia, Uganda, Rwanda and Burundi, southwestern Niger, and Madagascar are likely to remain hotspots of food insecurity, while regions located in Tanzania, Mozambique and the Democratic Republic of Congo might face more serious undernutrition. It is likely that both the groups of regions will suffer from lower capacity of importing food as well as lower per capita calorie availability, while the latter group will probably have sharper reduction in per capita calorie availability. Special attention must be paid to the hotspot areas in order to meet the hunger alleviation goals in SSA.
Globalisation, scientific and technical progress are the basis of numerous innovative therapies for oncologic and non-oncologic diseases. It is another matter how much and by whom they are desired, and whether they have to be applied. When and how often? Innovative approaches should go towards simplification, universal distribution and application while at the same time analysis between the potential initial investment and the achieved final result should be made. An illustrative example for this is the targeted therapy for melanoma with its low baseline criteria or basic rules for its surgical treatment. Another example could be the confocal microscopy in the context of dysplastic nevus syndrome. Therapies for various autoimmune diseases should also be considered critically. In the current OAMJMS issue, as well as in some of our other ideas and statements reported also in OAMJMS, we are trying to answer at least to a part of these dilemmas, to provoke a critical point of view and to ask some simple questions: “Should any innovation be considered as a face value? Which is potentially beneficial for our patients? How could we regulate the processes to minimise the need for expensive medications for certain diseases? And, of course, we are also turning to our own mistakes by visualising the results of them! PMID:29483969

The selection of proxy indicators proved a valuable basis for robust palaeo-climatic reconstructions, with the resolution ranging from multi-decadal (NAM1 over centennial (core 178 to millennial scale (core 226620. The northern Benguela experienced pronounced and rapid perturbation during the middle and late Holocene, and apparently, not all are purely local in character. In fact, numerous correlations with records from the adjacent South African subcontinent and the northern hemisphere testify to global climatic teleconnections. The Holocene Hypsithermal, for instance, is just as evident as the Little Ice Age (LIA and the Roman Warm Period. The marked SST-rise associated with the latter is substantiated by other marine and terrestrial data from the South African realm. The LIA (at least its early stages manifests itself in intensified winds and upwelling, which accords with increased rainfall receipts above the continental interior. It appears that climate signals are transferred both via the atmosphere and ocean. The combined analysis of SST and Tδ18O proved a useful tool in order to differentiate between both pathways. SSTs are primarily controlled by the intensity of atmospheric circulation features, reflecting changes of upwelling-favourable winds.

The beginning of the marble extraction activity in the Macael Area (Almería, South of Spain) date back 4000 years ago, and since then, it has been used in several and important monuments, principally, in Spain. The quality of the works carried out is more than proven. During this time, the extraction has alternated periods of activity with others of lesser or none-activity, ruling both the lives of the inhabitants of the region, and its landscape. The most well-known material extracted in the region, with international recognition, is marble "Blanco Macael" (White Macael), traditionally compared with "Carrara marble". But there are other marbles such as "Amarillo Macael", "Gris Macael" or "Anasol", as well as serpentinites that are referred as "Verde Macael" or "Verde Almería". All of them have been employed in many recent important buildings, at national and international level. The problem of this intensive activity through the years, from the point of view of the preservation of the old landscapes, is that the modern quarries have replaced the old ones, leaving few remains of the old quarries. In some cases it is possible to see Muslim vestiges (e.g. "Puntilla"), but this is an exception. Notwithstanding, the landscape of the region has a high value due to the combination of high mountains, high faces with a lot of banks, waste dumps and full restored areas. Nowadays, the surface occupied by mining exploitation, only in the closer area to Macael village, is more 8.5 km2, with more than forty active quarries and many abandoned ones. These features have helped to configure a singular and beautiful landscape, possibly unique in Spain, in relation with an historic mining activity. This is an important added value to the possible candidature of the "Blanco Macael" as a "Global Heritage Stone Resource" and the "Macael Region" as a "Global Heritage Stone Province", mostly if we consider that these designations must take into consideration the social importance of the

In 2003, nuclear power received renewed interest as a perceived climate-neutral way to meet high energy demands of large industrialized countries, such as China, India, Russia and the USA. It triggered a growing demand for uranium (U) as nuclear fuel. Dubbed the 'nuclear renaissance', the U-price rose over tenfold before the global credit crisis dampend the rush. Many efforts to capitalise on the renewed demand focused on Africa. This paper provides an overview on the type and extent of uranium mining, production and exploration on the African continent and discusses the economic benefits as well as the potential environmental and health risks and the long-term needs for remediation of legacy sites. The actual historical results of uranium mining activities in more than thirty African countries provide data against which to assess the existing risks of uranium development. The already existing uraniferous waste in several African countries threatens scarce water resources and the health of adjacent residents. Responsibility should rest with the governments and the companies to ensure that these threats are not realized.

Full Text Available The article explores the global overview of M&E from the ancient governance perspective that has been ignored by the modern government in the African contest. African M&E approach is required in the local rural municipalities due to its complex and diverse set of problems. These problems are as a result of leadership dichotomy which is witnessed between Amakhosi and municipal authorities. Amakhosi have a role to hold municipal authorities accountable from a Citizen-Based Approach. The underlying philosophy of the article is not about the discourse of the modernists and traditionalists around the evolution of M&E, but is how and in what ways M&E should be designed and planned for the implementation of a successful relevant M&E approach for local rural municipalities. The article made use of secondary data, gathered from various sources. Case studies of the international countries were also sourced through desktop to ascertain their best practice on M&E. The article concludes that the lack of M&E approach for the local government in the rural municipalities requires the Participatory Monitoring and Evaluation (PM&E approach to allow stakeholders, including Amakhosi to assess the performance ofthe rural municipalities. The study is significant to the local and internal public scholarship of public administration since it bring approaches in M&E policy in the field of public administration. For example, indigenous African knowledge is critical in knowledge management.

Purpose: – The purpose of this paper is to examine the effect of cultural intelligence (CQ) on the job performance of global managers. Design/methodology/approach: – In total, 332 global managers were surveyed from multinational companies operating in Brazil. The mediating effect of job...... satisfaction was tested on the CQ-job performance relationship. Findings: – The findings suggest that job satisfaction transmits the effect of CQ to job performance, such that global managers high in CQ exhibit more job satisfaction in an international setting, and therefore perform better at their jobs....... Practical implications: – Results imply that global managers should increase their CQ in order to improve their job satisfaction and ultimately perform better in an international context. Originality/value: – The authors make three primary contributions to the international business literature. First...
Full Text Available This paper attempts to review and reconsider the role of context in mobile learning and starts by outlining definitions of context-aware mobile learning as the technologies have become more mature, more robust and more widely available and as the notion of context has become progressively richer. The future role of context-aware mobile learning is considered within the context of the future of mobile learning as it moves from the challenges and opportunities of pedagogy and technology to the challenges and opportunities of policy, scale, sustainability, equity and engagement with augmented reality, «blended learning», «learner devices», «user-generated contexts» and the «internet of things». This is essentially a perspective on mobile learning, and other forms of technology-enhanced learning (TEL, where educators and their institutions set the agenda and manage change. There are, however, other perspectives on context. The increasing availability and use of smart-phones and other personal mobile devices with similar powerful functionality means that the experience of context for many people, in the form of personalized or location-based services, is an increasingly social and informal experience, rather than a specialist or educational experience. This is part of the transformative impact of mobility and connectedness on our societies brought about by these universal, ubiquitous and pervasive technologies. This paper contributes a revised understanding of context in the wider context (sic of the transformations taking place in our societies. These are subtle but pervasive transformations of jobs, work and the economy, of our sense of time, space and place, of knowing and learning, and of community and identity. This leads to a radical reconsideration of context as the notions of ‹self› and ‹other› are transformed.
Full Text Available Urban areas are among the most important centres of invasive plant species distribution due to their richness in alien species. Because of that, a detailed floristic analysis of perennial flowerbeds was conducted in the central parks of Belgrade. A total of 53 perennial species were found, of which 55% were the alien species planted on 75% of the research area. Among them, two species (Aster novi belgii and Solidago canadensis are invasive and six species are potentially invasive in Serbia. These are planted on 5% and 20% of the flowerbeds, respectively. We can conclude that both the experts and institutions should be informed about the invasive species and potential damages. In the meantime, planting of native decorative species should be encouraged, since they will not pose a threat to natural habitats. Also, detailed research should be conducted in order to eradicate invasive and potentially invasive species from the surfaces around the research area.

All trees with DAP >10 cm situated in 75 permanent plots of 1 ha were inventoried. 27,126 individuals trees (361 ind.ha-1), distributed in 59 botanical families, comprising 481 species were observed. The families with the largest number of species were Fabaceae (94), Araceae (65) and Arecaceae (43), comprising 43.7% of total species. The species Alexa grandiflora (4.41), Cenostigma tocantinum (2.50) and Bertholletia excelsa (2.28) showed the highest importance values (IV). The ten species with greater IV are concentrated (22%). The forest community has high species richness and can be classified as diverse age trees, heterogeneous and of medium conservation condition.

Morphological and DNA sequence characteristics of a pathogenic fungus isolated from branch cankers in Proteaceae of the South West Australian Floristic Region elucidated a new genus and species within Cryphonectriaceae (Diaporthales). The pathogen has been isolated from canker lesions in several Banksia species and Lambertia echinata subsp. citrina, and is associated with a serious decline of the rare B. verticillata. Lack of orange pigment in all observed structures except cirrhi, combined with pulvinate to globose black semi-immersed conidiomata with paraphyses, distinguishes the canker fungus from other genera of Cryphonectriaceae. This was confirmed by DNA sequence analysis of the ITS regions, β-tubulin, and LSU genes. The fungus (sexual morph unknown) is described as Luteocirrhus shearii gen. sp. nov. Lesions in seedlings of Banksia spp. following wound inoculation and subsequent recovery confirm Koch's postulates for pathogenicity. This pathogen of native Proteaceae is currently an emerging threat, particularly toward B. baxteri and B. verticillata.

Wadi Arar in the Northern border region of Saudi Arabia is one of the most important Wadis of the Kingdom. The present study provides an analysis of vegetation types, life forms, as well as floristic categories and species distribution. A total of 196 species representing 31 families of vascular plants were recorded. Compositae, Gramineae and Leguminosae were the most common families. Therophytes and chamaephytes are the most frequent life forms, indicating typical desert spectrum vegetation. The distribution of these species in the different sectors of the Wadi as well as the phytochoria for the recorded species is provided. Ninety-one species (46.5%) are typical bi-regional. Furthermore, about 105 species (53.5%) are mono- or pluriregional taxa. The highest number of species (136 or 69.5%) was recorded for annual plants, while the lowest number of species (60% or 30.5%) was recorded for perennial, short perennial or annual to biennial species.

Full Text Available The aim of the article is to determine the nature of financial integration and to justify its place in the system of measures on state regulation intended to search for a balanced model of economic growth of the country through the impossible trilemma reflecting the impossibility of simultaneous implementation of three macro-economic policies in one country, namely financial openness, monetary independence and exchange rate stability. On the basis of synthesis, analysis and comparison of different interpretations, the concept of «financial integration» is clarified. There identified signs of integration of financial markets, such as: the uniformity of rules (transparency; equal access (availability; common operating environment (involvement; equity of prices (unity; uniformity of the reaction of financial assets on the impact of external trends and news (response. The policy of financial integration, in particular its component of the free movement of capital is designed to provide additional incentives to domestic economic growth by attracting external financial resources. To stimulate the economy and prevent the unstable volatility of exchange rate, many countries seek to achieve such macroeconomic goals as openness of financial markets, independence of the monetary policy and exchange rate stability. Since the monetary authorities may choose at any moment only two of the three goals, the Mundell-Fleming trilemma determines a possibility of three different combinations of monetary targeting. At present science has not developed a unified methodological approach to determination of indices of financial integration. To assess the dynamics of financial integration the following basic indices of integration are used: KAOPEN, FINREFORM, KASHI, etc. Based on the analysis of the mentioned indices in the context of different countries, there can be made a conclusion about a possibility of combination of different policies with a tendency towards

Full Text Available Abstract Background This paper describes the process used to develop an integrated set of culturally sensitive, evidence-based counselling tools (job aids by using qualitative participatory research. The aim of the intervention was to contribute to improving infant feeding counselling services for HIV positive women in the Kilimanjaro Region of Tanzania. Methods Formative research using a combination of qualitative methods preceded the development of the intervention and mapped existing practices, perceptions and attitudes towards HIV and infant feeding (HIV/IF among mothers, counsellors and community members. Intervention Mapping (IM protocol guided the development of the overall intervention strategy. Theories of behaviour change, a review of the international HIV/IF guidelines and formative research findings contributed to the definition of performance and learning objectives. Key communication messages and colourful graphic illustrations related to infant feeding in the context of HIV were then developed and/or adapted from existing generic materials. Draft materials were field tested with intended audiences and subjected to stakeholder technical review. Results An integrated set of infant feeding counselling tools, referred to as 'job aids', was developed and included brochures on feeding methods that were found to be socially and culturally acceptable, a Question and Answer Guide for counsellors, a counselling card on the risk of transmission of HIV, and an infant feeding toolbox for demonstration. Each brochure describes the steps to ensure safer infant feeding using simple language and images based on local ideas and resources. The brochures are meant to serve as both a reference material during infant feeding counselling in the ongoing prevention of mother to child transmission (pMTCT of HIV programme and as take home material for the mother. Conclusion The study underscores the importance of formative research and a systematic theory

Highlights: • Assessing the role and performance of SDC and PSS2B in deregulated power markets. • The profit allocation of WADC as an AS provider is involved in this work. • A dual-dimensional SDC scheme for UPFC is applied to damp the power system swings. • The high share of dual-dimensional SDC shows capability of it in enhancing security. - Abstract: The problem of profit allocation of Unified Power Flow Controller-Supplementary Damping Controller (UPFC-SDC) and accelerating power PSS model (PSS2B) is an important and update issue which has not been properly directed yet. The model of UPFC-SDC that has been used in this paper is a dual-dimensional controller that first dimension of control is resulted from local signals and the second dimension is covered by global signals as additional measuring data from appropriate remote network locations, where swings are well observable. Thus, in this paper the profit allocation of Wide Area Damping Controller (WADC) is also presented as an undefined problem in security subject of deregulated power system. Assuming control action by UPFC-SDC and WADC as an Ancillary Service (AS), the contribution of UPFC-SDC in stability enhancement is evaluated. It is important to appropriately choose a criterion to assess the performance of UPFC-SDC, so that a suitable allocation of profit can be achieved. The sum of deviations of damping ratios and real part of eigenvalues is selected as Oscillation Damping Criterion (ODC). Two scenarios for valuation of small signal stability as an AS provided by UPFC-SDC is considered. The first scenario without retuning of controllers and in the second scenario controllers is retuned due to response of the market situation. A multi-objective optimization approach based on ODC, generation costs and UPFC cost is considered and then Non-Dominated Sorting Genetic Algorithm-II (NSGA-II) is utilized for solving this problem. A two area four machine test power system is considered for investigation

Full Text Available The Himalayan Kingdom of Bhutan, located in one of the global biodiversity hotspots, is endowed with abundant floral wealth, including a wide array of medicinal plants (MPs. However, over-exploitation of these resources is widespread, and only a few studies have assessed the richness and diversity of Bhutanese forests and in particular about the MP resources. A vegetation survey was conducted in Tshothang Chiwog, south-eastern Bhutan to characterize the floristic structure of the broad-leaf mixed coniferous forests with a special focus on MPs. A questionnaire survey involving 40 farmers was also conducted to assess the ethnobotanical and socioeconomic aspects of MP extraction. A total of 157 plant species (38 trees, 19 shrubs, 85 herbs and ferns, and 15 climbers, representing 74 families and 137 genera were identified from the study area, of which 69 species (14 trees, 10 shrubs, 38 herbs and ferns, and seven climbers, belonging to 41 families and 69 genera were medicinally important. The most species-rich families of medicinal plants were: Asteraceae (eight spp., Apiaceae (four spp., Polygonaceae, Brassicaceae, Zingiberaceae, and Urticaceae (three species each. Herbaceous flora exhibited the highest diversity (Simpson diversity index, D = 0.97 and Shannon-Weiner index, H′ = 5.82, followed by trees and shrubs (D = 0.95 and 0.92 and H′ = 4.86 and 3.97, respectively. All but one herb showed abundance-to-frequency ratio (A/F ≥0.05, signifying a contagious distribution pattern (large aggregated distribution. Girth class distribution of trees followed an inverse J-shaped pattern. Results of the ethnobotanic study documented 55 MPs. MP collection, as reported by the interviewees, generally improved the socioeconomic status of the people of Tshothang Chiwog. Apart from improving the livelihood security of the local people, aspects relating to health care and culture are also important. Respondents were also concerned about the declining MP wealth

Full Text Available Este artigo tem como objetivo analisar os desafios do acesso à água para consumo humano, considerando-se o contexto internacional e nacional. A partir da deliberação da ONU de que o acesso à água limpa e segura é um direito fundamental de todo ser humano são identificadas vulnerabilidades que podem se constituir em restrições ao acesso. A distribuição da água e das populações no planeta, a poluição, as políticas e gestões inadequadas produzem injustiça ambiental. A iniquidade de acesso a água constitui-se na crise contemporânea da água. A partir da década de 1980, emerge o mercado transnacional de água pelo controle privado que ocorre em três níveis principais: de mananciais superficiais e subterrâneos; de água engarrafada; e dos serviços públicos de abastecimento. Os conflitos dos usos múltiplos dos recursos hídricos, do mercado e dos problemas ambientais têm contribuído para a vulnerabilização da saúde das populações e dos ecossistemas. São necessárias políticas públicas adequadas ao exercício do direito humano fundamental de acesso a água com qualidade.The scope of this article is to analyze the challenges involved in ensuring access to water for human consumption taking the international and national context into consideration. Based on the UN declaration that access to safe and clean drinking water is a fundamental human right, vulnerabilities are identified that can consist in restrictions to access to adequate supplies. The distribution of water and the population across the planet, pollution, inadequate policies and management lead to environmental injustice. The iniquity of access to water constitutes the contemporary water crisis. From the 1980s onwards, the transnational water market emerged for private control that occurs at three main levels: surface and underground water sources; bottled water; and public water supply services.

Based on morphology, both new species belong to the Cape Clade of Indigofera, supporting a biogeographical link between the Cape Floristic Region and the Sneeuberg, as well as with the rest of the eastern Great Escarpment.
A Novel Strategy for Very-Large-Scale Cash-Crop Mapping in the Context of Weather-Related Risk Assessment, Combining Global Satellite Multispectral Datasets, Environmental Constraints, and In Situ Acquisition of Geospatial Data.
Dell'Acqua, Fabio; Iannelli, Gianni Cristian; Torres, Marco A; Martina, Mario L V
Cash crops are agricultural crops intended to be sold for profit as opposed to subsistence crops, meant to support the producer, or to support livestock. Since cash crops are intended for future sale, they translate into large financial value when considered on a wide geographical scale, so their production directly involves financial risk. At a national level, extreme weather events including destructive rain or hail, as well as drought, can have a significant impact on the overall economic balance. It is thus important to map such crops in order to set up insurance and mitigation strategies. Using locally generated data-such as municipality-level records of crop seeding-for mapping purposes implies facing a series of issues like data availability, quality, homogeneity, etc. We thus opted for a different approach relying on global datasets. Global datasets ensure homogeneity and availability of data, although sometimes at the expense of precision and accuracy. A typical global approach makes use of spaceborne remote sensing, for which different land cover classification strategies are available in literature at different levels of cost and accuracy. We selected the optimal strategy in the perspective of a global processing chain. Thanks to a specifically developed strategy for fusing unsupervised classification results with environmental constraints and other geospatial inputs including ground-based data, we managed to obtain good classification results despite the constraints placed. The overall production process was composed using "good-enough" algorithms at each step, ensuring that the precision, accuracy, and data-hunger of each algorithm was commensurate to the precision, accuracy, and amount of data available. This paper describes the tailored strategy developed on the occasion as a cooperation among different groups with diverse backgrounds, a strategy which is believed to be profitably reusable in other, similar contexts. The paper presents the problem

This work is an integral part of a project co-financed by the European Union "Environmental recovery of degraded soils and desertified land by a new technology treatment for the recovery of the land" (Life 10 ENV IT 400 "New Life"); this technology is based on a treatment (patented by m.c.m. Ecosistemi) of chemical mechanical processing of degraded soils with an initial process of disgregation of the same followed by their reconstitution incorporating soil matrices, a subsequent polycondensation with humic acids and a final restoration. The area of intervention of the New Life project lies in the municipal territory of Piacenza, where between the years 70 and 80 has been made a landfill for municipal solid waste with subsequent restoration work by placing a layer of soil cover. The first phase of the New Life project was that of a physical and chemical characterization of different cover soils of the area combined with floristic-vegetational analysis. At this stage the present study aims to compare the data related to the analysis of the vegetation with those returned by investigation of hydrological characteristics of soils performed by laboratory methods, together to confront two theoretical calculation methods for determination of hydrological parameters. The comparison of the ecological study of the vegetation with the outcomes obtained by the classical methods regarding the determination of water retention, allows you to have a picture that is as detailed as possible in describing the characteristics of the substrate. The comparison also with the two methods of calculation, which determines the hydrological character conditions in average soil condition, allows you to ascertain the actual disturbance of the soil in the area. In order to delineate the hydrological characteristics of the soils sampled, were quantified by the Maximum Water Concentration, the capacity range, the point of Withering by the method of the Tensiometric box and the Pressure Membrane

Full Text Available Variations in vegetation based on topographic location have become an interest of researchers. However, few studies have verified floristic associations related to the topographic position of a slope. In this work, we analyzed if variations in vegetation allow floristic groups to be detected in a subtropical moist forest. The vegetation was sampled in 25 plots of 400 m² distributed systematically, where individuals with a DBH ≥ 5.0 cm were measured. We sampled 1,727 individuals and 144 species. The NMDS ordination segregated three groups based on the topographic position of the slope (Monte Carlo, P ≥ 0.05; ANOSIM, P < 0.001. Euterpe edulis and Sloanea guianensis were notable in the lower and middle sections of the slope, whereas Ocotea aciphylla and Alchornea triplinervia were notable in the upper section. Some species were indicators of the analyzed sectors, such as Actinostemon concolor and Alsophila setosa in the lower section, Cyathea corcovadensis and Rudgea recurva in the middle section, and Myrcia pulchra and Podocarpus sellowii in the upper section. Our results indicate that the floristic and structural variations observed by Veloso and Klein (1959 and Klein (1980; 1984 for Vale do Itajaí in Santa Catarina are statistically valid today, because we verified the formation of different groups according to the topographic position of the slope.
Comparative method is widely used in the paper. Gini Coefficient and Percentage of Total Income of National Population by Income Quintile are utilized as main indicators, and the two results just mutually verify each other. We find that the huge inequality in China does not fit into the title of socialist country and its socialist extent is far less than the European's, even inferior to typical capitalist countries. Finally, we make a ladder target of the Gini coefficient standards for Chinese government to keep constraint by oneself.

One of the most remarkable examples of intercontinental disjunction of the North Temperate Flora involves eastern Asia and eastern and western North America. Although there has been considerable interest in this phytogeographic pattern for over 150 years (e.g., Gray, 1859; Li, 1952; Graham, 1972; Boufford and Spongberg, 1983; Wu, 1983; Tiffney, 1985a, 1985b), relationships among taxa displaying the disjunction remain obscure. Understanding phylogenetic relationships is, however, a prerequisite for historical biogeographic analyses of this distributional pattern. To understand better the relationships of taxa displaying this intercontinental disjunction, phylogenetic analyses were conducted using a variety of DNA data sets for species of four genera (Cornus, Boykinia, Tiarella, and Trautvetteria) that occur in eastern Asia, eastern North America, and western North America. An area cladogram was constructed for each of the four genera, all of which show a similar pattern of relationship: the eastern Asian species are sister to all North American species. An identical phylogenetic pattern is also found in three other taxa exhibiting this disjunction (Aralia sect. Aralia, Calycanthus, and Adiantum pedatum). The congruent phylogenetic pattern found in these seven diverse genera raises the possibility of a common origin of the eastern Asia, eastern and western North America disjunction. The data are in agreement with the long-standing hypothesis that this well-known floristic disjunction represents the fragmentation of a once continuous Mixed Mesophytic forest community and suggest that the disjunction may have involved only two major vicariance events: an initial split between Eurasia and North America, followed by the isolation of floras between eastern and western North America. However, congruence between phylogenies and geographic distributions does not necessarily indicate an identical phytogeographic history. Taxa exhibiting the same phylogenetic pattern may have
Meeting the health and social care needs of pregnant asylum seekers; midwifery students' perspectives: part 3; "the pregnant woman within the global context"; an inclusive model for midwifery education to address the needs of asylum seeking women in the UK.
Haith-Cooper, Melanie; Bradshaw, Gwendolen
to describe the conceptualisation and development of an inclusive educational model. The model is designed to facilitate pre-registration midwifery students' learning around the health and social care needs of pregnant women seeking asylum in the United Kingdom. current literature has identified a concern about the standard of maternity care experienced by asylum seeking women accessing maternity services in the United Kingdom. In response to this, a doctorate study was undertaken which focused on examining the way in which a group of midwifery students approached the provision of care for asylum seekers. This study revealed difficulties that these students had both in identifying these women's needs and also in the wider care issues in practice. Consequently, one of the recommendations was to ameliorate these difficulties through midwifery education. the key findings from this study were used together with relevant supporting literature to construct "the pregnant woman within the global context" model for midwifery education. The model is designed to facilitate a holistic assessment of need rather than focusing on the physical assessment at the expense of other aspects of care. It incorporates wider factors, on a global level, which could impact on the health and social care needs of a pregnant woman seeking asylum. It also prompts students to consider the influence of dominant discourses on perceptions of asylum seek;ing and is designed to encourage students' to question these discourses. this model can be used in midwifery education to prepare students in caring for pregnant women seeking asylum. It may be especially helpful when students have close contact with pregnant women seeking asylum, for example through caseloading. Further research is recommended to evaluate the effectiveness of this model in enhancing the care of asylum seeking women in the United Kingdom. Crown Copyright © 2012. Published by Elsevier Ltd.

Educational research has identified how science, technology, engineering, and mathematics (STEM) practice and education have underperforming metrics in racial and gender diversity, despite decades of intervention. These disparities are part of the construction of a culture of science that is alienating to these populations. Recent studies in a social science framework described as "Generative Justice" have suggested that the context of social and scientific practice might be modified to bring about more just and equitable relations among the disenfranchised by circulating the value they and their non-human allies create back to them in unalienated forms. What is not known are the underlying principles of social and material space that makes a system more or less generative. I employ an autoethnographic method at four sites: a high school science class; a farm committed to "Black and Brown liberation"; a summer program geared towards youth environmental mapping; and a summer workshop for Harlem middle school students. My findings suggest that by identifying instances where material affinity, participatory voice, and creative solidarity are mutually reinforcing, it is possible to create educational contexts that generate unalienated value, and circulate it back to the producers themselves. This cycle of generation may help explain how to create systems of justice that strengthen and grow themselves through successive iterations. The problem of lack of diversity in STEM may be addressed not merely by recruiting the best and the brightest from underrepresented populations, but by changing the context of STEM education to provide tools for its own systematic restructuring.

The Brazilian Atlantic Forest presents high levels of richness and endemism of several taxonomic groups. Within this forest, the Orchidaceae may be highlighted as the richest family of Angiosperms found there, and is highly threatened due to collection and habitat destruction. The inselbergs of the Brazilian Atlantic Forest are mostly unknown regarding their floristic composition, but the available information points to occurrence of endemic species, with adaptations to survive to this dry environment. The objectives of this study were to conduct a floristic survey of the Orchidaceae species on the Maciço do Itaoca, an inselberg located in the Northern region of the State of Rio de Janeiro, make a comparative analysis with other sites in Eastern Brazil, and discuss the geographic distribution, floristic relationships and conservation status of the orchid species present on the inselbergs. The floristic composition of the study area was compared with 24 other locations in Eastern Brazil (of which 13 are inselbergs) and the influence of the types of surrounding vegetation on the composition of the Orchidaceae flora on the inselbergs. On Maciço do Itaoca we recorded 18 species from 17 genera: Brasiliorchis picta, Brassavola tuberculata, Campylocentrum robustum; C sellowii, Catasetum luridum, Cattleya guttata, Cyclopogon congestus, Cyrtopodium glutiniferum, Leptotes bicolor, Lophiaris pumila, Miltonia moreliana, Oeceoclades maculata, Phymatochilum brasiliense, Prescottia plantaginifolia, Pseudolaelia vellozicola, Sarcoglottis fasciculata, Sophronitis cernua. and Vanilla chamissonis. The highest floristic similarity was with the Pedra da Botelha (0.43), an inselberg located in the North of Espírito Santo. This result is probably due to the similarity in altitude and distance from the coast in both areas despite the geographical distance between them. Apparently, little influence is exerted by the types of surrounding vegetation on the composition of the flora of

The disproportionate species richness of the world's biodiversity hotspots could be explained by low extinction (the evolutionary "museum") and/or high speciation (the "hot-bed") models. We test these models using the largest of the species rich plant groups that characterise the botanically diverse Cape Floristic Region (CFR): the genus Erica L. We generate a novel phylogenetic hypothesis informed by nuclear and plastid DNA sequences of c. 60 % of the c. 800 Erica species (of which 690 are endemic to the CFR), and use this to estimate clade ages (using RELTIME; BEAST), net diversification rates (GEIGER), and shifts in rates of diversification in different areas (BAMM; MuSSE). The diversity of Erica species in the CFR is the result of a single radiation within the last c. 15 million years. Compared to ancestral lineages in the Palearctic, the rate of speciation accelerated across Africa and Madagascar, with a further burst of speciation within the CFR that also exceeds the net diversification rates of other Cape clades. Erica exemplifies the "hotbed" model of assemblage through recent speciation, implying that with the advent of the modern Cape a multitude of new niches opened and were successively occupied through local species diversification.

The Greater Cape Floristic Region (GCFR) in South Africa has been extensively investigated for its phenomenal angiosperm diversity. A key emergent pattern is the occurrence of older plant lineages in the southern Fynbos biome and younger lineages in the northern Succulent Karoo biome. We know practically nothing, however, about the evolutionary history of the animals that pollinate this often highly-specialized flora. In this study, we explore the evolutionary history of an important GCFR fly pollinator, Megapalpus capensis, and ask whether it exhibits broadly congruent genetic structuring and timing of diversification to flowering plants within these biomes. We find that the oldest M. capensis lineages originated in Fynbos during the Miocene, while younger Succulent Karoo lineages diverged in the Pliocene and correspond to the proposed age of this recent biome. A strong signature of population expansion is also recovered for flies in this arid biome, consistent with recent colonization. Our first investigation into the evolutionary history of GCFR pollinators thus supports a recent origin of the SK biome, as inferred from angiosperm phylogenies, and suggests that plants and pollinators may have co-diverged within this remarkable area.
