Selected AbstractsImplementing Affirmative Action: Global TrendsIDS BULLETIN, Issue 5 2010Julie Ballington This scoping article gives a global picture of dynamics, trends, policies and mechanisms for engaging with women's representation in political office. It discusses the kind of affirmative action introduced, and where it features vis-à-vis electoral cycles. It describes and compares candidate and reserved seats quotas and shows how electoral systems influence the possibilities of challenging power hierarchies in politics. The second part of the article reflects on the extent to which implementing quotas have been effective in engendering political representation and the conditions that allow or inhibit this. [source] International Migration at the Beginining of the Twenty-First Century: Global Trends and IssuesINTERNATIONAL SOCIAL SCIENCE JOURNAL, Issue 165 2000Stephen Castles Globalisation leads to increases in all kinds of cross-border flows, including movements of people. In recent years international migrationhas grown in volume, and is now an important factor of social transformation in all regions of the world. States classify migrants into certain categories, and seek to encourage certain types of mobility while restricting others. However,control measures are often ineffective if they are not based on understanding of the economic, social and cultural dynamics of migration. The article reviews causes and patterns of migration, and discusses some key issues: migration anddevelopment, international cooperation, settle-ment and ethnic diversity, and migration as a challenge to the nation-state. It is argued that most national governments have taken a short-term and reactive approach to migration. Effortsat international regulation are also relatively under-developed. There is a need for long-term cooperative strategies to achieve agreed goals such as: ensuring orderly migration and preventing exploitation by agents and recruiters;safeguarding the human rights of migrants; making migration an instrument of sustainable development; avoiding conflicts with populations of migrant-receiving areas, and maximising positive aspects of social and culturalchange. [source] Demography, Education, and Democracy: Global Trends and the Case of IranPOPULATION AND DEVELOPMENT REVIEW, Issue 2 2010Wolfgang Lutz Reconstructions and projections of populations by age, sex, and educational attainment for 120 countries since 1970 are used to assess the global relationship between improvements in human capital and democracy. Democracy is measured by the Freedom House indicator of political rights. Similar to an earlier study on the effects of improving educational attainment on economic growth, the greater age detail of this new dataset resolves earlier ambiguities about the effect of improving education as assessed using a global set of national time series. The results show consistently strong effects of improving overall levels of educational attainment, of a narrowing gender gap in education, and of fertility declines and the subsequent changes in age structure on improvements in the democracy indicator. This global relationship is then applied to the Islamic Republic of Iran. Over the past two decades Iran has experienced the world's most rapid fertility decline associated with massive increases in female education. The results show that based on the experience of 120 countries since 1970, Iran has a high chance of significant movement toward more democracy over the following two decades. [source] The US National Intelligence Council on Growing Global MigrationPOPULATION AND DEVELOPMENT REVIEW, Issue 4 2001Article first published online: 27 JAN 200 The National Intelligence Council, a body reporting to the Director of Central Intelligence, brings together expertise from inside and outside the US government to engage in strategic thinking on national security issues. Some of its reports, known as National Intelligence Estimates, are now issued in unclassified versions. One of these published in December2000, was entitled Global Trends 2015: A Dialogue about the Future with Nongovernment Experts. It discussed what it termed the key drivers of global change and presented a generally bleak set of scenarios of the medium-term future. (See the short review in PDR 27, no. 2, pp. 385,386.) Demographic factors,in particular, mass migration,were seen as one of the drivers. This topic is investigated further in a subsequent NIC report, Growing Global Migration and Its Implications for the United States, issued this year. The initial section of the report, headed Key Judgments, is reprinted below. The report emphasizes the economic advantages of liberal immigration policies to the advanced economies, "despite some initially higher welfare costs and some downward pressure on wages." Resistance to liberalization in European countries and Japan is seen as putting them at a competitive disadvantage to the United States. Their levels of illegal immigration, however, will inevitably increase in scale. Expectations for the US are for rises in both legal and illegal immigration. Mentioned as one of the "difficult issues" that are minor offsets to the broad gains offered by immigration is its use as a vehicle for "transnational terrorist, narcotrafficking, and organized crime groups." The full report is available online at http://www.cia.gov/nic/pubs/index.htm. [source] Federalism: Fuzzy Global TrendsAUSTRALIAN JOURNAL OF POLITICS AND HISTORY, Issue 1 2004Ken Coghill This article examines the operation of federalism from the perspective of complex evolving socio-political systems. Emerging forms of governance that operate through a mix of formal statutory instruments, culture and the effects of fuzzy logic rather than in accordance with formal constitutional provisions are examined. The paper will canvas the implications of this approach for certain specific areas of public administration within the Australian federation. [source] Global trends in senesced-leaf nitrogen and phosphorusGLOBAL ECOLOGY, Issue 5 2009Zhiyou Yuan ABSTRACT Aim, Senesced-leaf litter plays an important role in the functioning of terrestrial ecosystems. While green-leaf nutrients have been reported to be affected by climatic factors at the global scale, the global patterns of senesced-leaf nutrients are not well understood. Location, Global. Methods, Here, bringing together a global dataset of senesced-leaf N and P spanning 1253 observations and 638 plant species at 365 sites and of associated mean climatic indices, we describe the world-wide trends in senesced-leaf N and P and their stoichiometric ratios. Results, Concentration of senesced-leaf N was highest in tropical forests, intermediate in boreal, temperate, and mediterranean forests and grasslands, and lowest in tundra, whereas P concentration was highest in grasslands, lowest in tropical forests and intermediate in other ecosystems. Tropical forests had the highest N : P and C : P ratios in senesced leaves. When all data were pooled, N concentration significantly increased, but senesced-leaf P concentration decreased with increasing mean annual temperature (MAT) and mean annual precipitation (MAP). The N : P and C : P ratios also increased with MAT and MAP, but C : N ratios decreased. Plant functional type (PFT), i.e. life-form (grass, herb, shrub or tree), phylogeny (angiosperm versus gymnosperm) and leaf habit (deciduous versus evergreen), affected senesced-leaf N, P, N : P, C : N and C : P with a ranking of senesced-leaf N from high to low: forbs , shrubs , trees > grasses, while the ranking of P was forbs , shrubs , trees < grasses. The climatic trends of senesced-leaf N and P and their stoichiometric ratios were similar between PFTs. Main conclusions, Globally, senesced-leaf N and P concentrations differed among ecosystem types, from tropical forest to tundra. Differences were significantly related to global climate variables such as MAT and MAP and also related to plant functional types. These results at the global scale suggest that nutrient feedback to soil through leaf senescence depends on both the climatic conditions and the plant composition of an ecosystem. [source] Corporate social responsibility in Malaysia , experts' views and perspectivesCORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 3 2009Jye Y. Lu Abstract The field of corporate social responsibility (CSR) has grown exponentially in the last decade and is gradually becoming a global trend. Companies are now expected to take explicitly into account all aspects of their performance, i.e., not just their financial results, but also their social and environmental performance. Therefore more organizations are now engaged in serious efforts to define and integrate CSR into all aspects of their businesses. The aim of our study is to understand this trend in Malaysia and specifically to investigate (i) The status of CSR in Malaysia; (ii) Different CSR practices in Malaysia; and (iii) Future diffusion of CSR in Malaysia. To answer these questions, we have conducted interviews with Malaysian leading experts in CSR. Our results suggests that the key issues in the journey toward wider diffusion and acceptance of CSR in Malaysia include current confusion over the meaning of CSR, the prevalent use of CSR as a PR tool, mandatory versus voluntary CSR and the role the National Mirror Committee of ISO/TMB/WG SR in this process.

[source] Rapid morphological change in stream beetle museum specimens correlates with climate changeECOLOGICAL ENTOMOLOGY, Issue 5 2008JENNIFER BABIN-FENSKE Abstract 1.,Climate change has been occurring at unprecedented rates and its impacts on biological populations is beginning to be well documented in the literature. For many species, however, long-term records are not available, and trends have not been documented. 2.,Using museum specimens from southern USA, we show that the stream-dwelling beetle Gyretes sinuatus has shown an 8% increase in body size and change in body shape (fineness ratio) from 1928 to 1988. Any directional morphological change observed over time could be an indicator of a microevolutionary response. 3.,During these 60 years, there have also been changes in temperature, precipitation, and location of collection sites. Unlike the global trend, mean annual temperature in the region has decreased, and furthermore, total annual precipitation has increased. By investigating how these various ecological and geographical variables may affect body size and shape, we can examine which pressures may promote larger and/or thinner beetles. 4.,Results indicate that mean annual temperature was the most predictive variable for the change in size and shape. We suggest there is an adaptive role for temperature on body size and shape of stream dwelling organisms. 5.,We found that museum specimens can be invaluable resources of information when collection date and location information is available. We promote the use of such specimens for future studies of the morphological response to climate change. [source] Global pattern of NPP to GPP ratio derived from MODIS data: effects of ecosystem type, geographical location and climateGLOBAL ECOLOGY, Issue 3 2009Yangjian Zhang ABSTRACT Aim, To examine the global pattern of the net primary production (NPP)/gross primary production (GPP) ratio of the Earth's land area along geographical and climatic gradients. Location, The global planetary ecosystem. Methods, The 4-year average annual NPP/GPP ratio of the Earth's land area was calculated using 2000,03 Moderate Resolution Imaging Spectroradiometer (MODIS) data. The global pattern of the NPP/GPP ratio was investigated by comparing it among each typical terrestrial ecosystem and plotting it along a geographical and climatic gradient, including latitude, altitude, temperature and precipitation. Results, The global terrestrial ecosystem had an average NPP/GPP ratio value of 0.52 with minor variation from 2000 to 2003. However, the NPP/GPP ratio showed considerable spatial variation associated with ecosystem type, geographical location and climate. Densely vegetated ecosystems had a lower NPP/GPP ratio than sparsely vegetated ecosystems. Forest ecosystems had a lower NPP/GPP ratio than shrub and herbaceous ecosystems. Geographically, the NPP/GPP ratio increased with altitude. In the Southern Hemisphere, the NPP/GPP ratio decreased along latitude from 30° to 10° and it exhibited high fluctuation in the Northern Hemisphere. Climatically, the NPP/GPP ratio exhibited a decreasing trend along enhanced precipitation when it was less than 2300 mm year,1 and a static trend when the annual precipitation was over 2300 mm. The NPP/GPP ratio showed a decreasing trend along temperature when it was between ,20 °C and 10 °C, and showed an increasing trend along rising temperature when it was between ,10 °C and 20 °C. Within each ecosystem, the NPP/GPP ratio revealed a similar trend to the global trend along temperature and precipitation. Conclusions, The NPP/GPP ratio exhibited a pattern depending on the main climatic characteristics such as temperature and precipitation and geographical factors such as latitude and altitude. The findings of this research challenge the widely held assumption that the NPP/GPP ratio is consistent regardless of ecosystem type. [source] Climate variability and change in the Greater Alpine Region over the last two centuries based on multi-variable analysisINTERNATIONAL JOURNAL OF CLIMATOLOGY, Issue 15 2009Michele Brunetti Abstract An extensive analysis of the HISTALP database is presented with the aim of giving a comprehensive picture of secular climate variability and change in the Greater Alpine Region (GAR, 4,19 E, 43,49 N). The HISTALP database encompasses 242 sites and concerns temperature, pressure, precipitation, cloudiness, sunshine duration, vapour pressure and relative humidity. The analyses are based on four regional mean records representing different GAR low-level areas and on an additional mean record representing high-level locations. The first goal of the paper is to give an overview of the seasonal and annual records for the different variables, aiming to highlight both variability on decadal time scale and long-term evolution. Then it focuses on trend and correlation analysis. Trends are presented both for the period of common data availability for all regional average series and for moving windows that permit studying the trends over a wide range of timescales. Correlations among the different variables are presented both for the regional average series and for their high-pass-filtered versions. The analyses, beside highlighting a warming that is about twice as large as the global trend, also show that the different variables have responded in different ways to this warming and that the mutual interactions linking the different variables are often present only at specific temporal scales and only in parts of the GAR and in defined seasons. In spite of this complex behaviour, which may also be due to some residual inhomogeneities still affecting the data, the analyses give evidence that the HISTALP database has an excellent internal consistency and show that the availability of a multi-variable database turns out to be very useful in order to evaluate the reliability of the reconstruction of each variable and to better understand the behaviour and the mutual interactions of the different variables. Copyright © 2009 Royal Meteorological Society [source] The Development of Advanced Nursing Practice GloballyJOURNAL OF NURSING SCHOLARSHIP, Issue 3 2008Barbara Sheer Purpose: To examine the development of advanced nursing practice globally. Methods: Data were collected from documentary resources available in the International Nurse Practitioners/Advanced Practice Nurse Network (INP/APNN) of the International Council of Nurses. The areas examined were guided by the "key informant survey on advanced nursing practice self-administered questionnaire." Two core members of the INP/APNN who have rich experience in global advanced nursing development analyzed the data. A total of 14 countries and three regions from five continents were included in the analyses. The development of advanced nursing practice in these areas is facilitated by a need for better access to care in a cost-containment era and the enhancement of nursing education to postgraduate level. The mechanism for regulation of practice is in place in some countries. Conclusions: Confirms the development of advanced practice in nursing is a global trend. Clinical Relevance: APNs can improve global health with points to enhanced education in nursing and regulation of advanced practice. [source] Renoprotective effect of Hemidesmus indicus, a herbal drug used in gentamicin-induced renal toxicityNEPHROLOGY, Issue 3 2004MANGALA S KOTNIS SUMMARY: Background and Aims: Owing to the global trend towards improved ,quality of life', there is considerable evidence of an increase in demand for medicinal plants. The WHO guidelines define basic criteria for the standardization of herbal medicines. The present work is an effort in this direction to prove the safety and efficacy of Hemidesmus indicus Linn. in the management of nephrotoxicity induced by aminoglycosides such as gentamicin. Methods and Results: Simple, quality control methods using high performance thin layer chromatographic (HPTLC) phytochemical fingerprint, proximate analysis, and the stability of the H. indicus root powder were developed. From the toxicity study using albino Swiss mice, it was observed that the drug (H. indicus) was relatively safe up to 7 g/kg bodyweight dose. Efficacy was evaluated against gentamicin-induced nephrotoxicity in albino Wister rats. The study examined animals from the following groups: no treatment, gentamicin treated, gentamicin treated recovery, and gentamicin and plant treated. Animals from all groups were killed on day 13 of the study; those from gentamicin treated group were killed on the seventh day. Assessment of the drug efficacy drug was conducted by using haematological and histological examination. Conclusion: The treatment with H. indicus helped in the management of renal impairment, which was induced by gentamicin in rats. This is evident from the results obtained for various kidney function tests for gentamicin, along with the results from the plant treated group, and is in comparison with the results found for the gentamicin recovery group. A histological examination of kidneys also supports the findings from haematological evaluations. The plant shows promise as an adjunct therapy along side aminoglycosides as it reduces nephrotoxicity caused by aminoglycosides. [source] Are Parents Investing Less Time in Children?POPULATION AND DEVELOPMENT REVIEW, Issue 4 2004Trends in Selected Industrialized Countries Trends in parental time invested in children since the 1960s are examined in 16 industrialized countries using time-use survey data. Despite the time pressures that confront today's families, parents appear to be devoting more time to children than they did 40 years ago. Results also suggest that mothers continue to devote more time to childcare than fathers, but the gender gap has been reduced. The consistency of these results across countries suggests a global trend toward an increase in parental time investment in children. Multivariate analysis of trends in parental time by type of activity was undertaken for Canada. It revealed a significant increase in parental time even after controlling for changes in the demographic composition of the population during the past few decades. [source] Autonomisation of the Thai state: some observationsPUBLIC ADMINISTRATION & DEVELOPMENT, Issue 1 2006Bidhya Bowornwathana Abstract This article argues that the recent global trend of creating autonomous or quasi-autonomous public arganisations must be understood within the particular context of the country under investigation. In the case of the Thai state, autonomisation should be seen as a transformation process from a unitary administrative system to multiple administrative systems. It is an escape from a very centralised form of government to a more decentralised one where government power is more dispersed among various public organisations. The nature of politics and administration determines the direction of the hybridisation processes of autonomisation in Thailand. The reform direction chosen by the prime minister and the relationship between politicians and bureaucrats are two key factors that dictate the direction of autonomisation.

Chan Despite the outward appearance of depoliticization, the civil service in China today is actually being repoliticized. This paper compares the 1993 Provisional Regulations on State Civil Servants with the Civil Service Law approved by the Standing Committee of the National People's Congress of the People's Republic of China (PRC) in April 2005. The 2005 reform formalized what had been a historical pattern,the Communist Party holds tight control over leadership change and management at various levels. The Civil Service Law has turned the Communist Party of China into a political institution that has become the source of both civil service empowerment and control. Although civil service reform in China differs markedly from approaches adopted elsewhere, China is clearly expanding its political control to ensure greater leverage over the bureaucracy. In this regard, China is in line with the global trend. That said, civil service reform in China has focused on structural elements and formal reorganizations, whereas most industrialized democracies have engaged in a dialectic between individualist and corporate responses to managerial questions. An understanding of the Chinese ability to adopt reforms,while strengthening its traditional hold,provides key perspectives not only on the world's largest nation and a rapidly emerging force in global political and economic relationships but also on the Chinese experience with important public sector reforms that have occurred in many other countries over recent decades. [source] Comparison of phenology trends by land cover class: a case study in the Great Basin, USAGLOBAL CHANGE BIOLOGY, Issue 2 2008BETHANY A. BRADLEY Abstract Direct impacts of human land use and indirect impacts of anthropogenic climate change may alter land cover and associated ecosystem function, affecting ecological goods and services. Considerable work has been done to identify long-term global trends in vegetation greenness, which is associated with primary productivity, using remote sensing. Trend analysis of satellite observations is subject to error, and ecosystem change can be confused with interannual variability. However, the relative trends of land cover classes may hold clues about differential ecosystem response to environmental forcing. Our aim was to identify phenological variability and 10-year trends for the major land cover classes in the Great Basin. This case study involved two steps: a regional, phenology-based land cover classification and an identification of phenological variability and 10-year trends stratified by land cover class. The analysis used a 10-year time series of Advanced Very High Resolution Radiometer satellite data to assess regional scale land cover variability and identify change. The phenology-based regional classification was more detailed and accurate than national or global products. Phenological variability over the 10-year period was high, with substantial shifts in timing of start of season of up to 9 weeks. The mean long-term trends of montane land cover classes were significantly different from valley land cover classes due to a poor response of montane shrubland and pinyon-juniper woodland to the early 1990s drought. The differential response during the 1990s suggests that valley ecosystems may be more resilient and montane ecosystems more susceptible to prolonged drought. This type of regional-scale land cover analysis is necessary to characterize current patterns of land cover phenology, distinguish between anthropogenically driven land cover change and interannual variability, and identify ecosystems potentially susceptible to regional and global change. [source] Trends and methodological impacts in soil CO2 efflux partitioning: A metaanalytical reviewGLOBAL CHANGE BIOLOGY, Issue 6 2006JENS-ARNE SUBKE Abstract Partitioning soil carbon dioxide (CO2) efflux (RS) into autotrophic (RA; including plant roots and closely associated organisms) and heterotrophic (RH) components has received considerable attention, as differential responses of these components to environmental change have profound implications for the soil and ecosystem C balance. The increasing number of partitioning studies allows a more detailed analysis of experimental constraints than was previously possible. We present results of an exhaustive literature search of partitioning studies and analyse global trends in flux partitioning between biomes and ecosystem types by means of a metaanalysis. Across all data, an overall decline in the RH/RS ratio for increasing annual RS fluxes emerged. For forest ecosystems, boreal coniferous sites showed significantly higher (P<0.05) RH/RS ratios than temperate sites, while both temperate or tropical deciduous forests did not differ in ratios from any of the other forest types. While chronosequence studies report consistent declines in the RH/RS ratio with age, no difference could be detected for different age groups in the global data set. Different methodologies showed generally good agreement if the range of RS under which they had been measured was considered, with the exception of studies estimating RH by means of root mass regressions against RS, which resulted in consistently lower RH/RS estimates out of all methods included. Additionally, the time step over which fluxes were partitioned did not affect RH/RS ratios consistently. To put results into context, we review the most common techniques and point out the likely sources of errors associated with them. In order to improve soil CO2 efflux partitioning in future experiments, we include methodological recommendations, and also highlight the potential interactions between soil components that may be overlooked as a consequence of the partitioning process itself. [source] Network, exposure and rhetoric: Italian occupational fields and heterogeneity in constructing the globalized selfGLOBAL NETWORKS, Issue 4 2003Massimiliano Monaci Drawing on the findings of a broad inter-university research programme conducted in Italy, in this article we explore how individuals' transnational networks combine with other dimensions of their social experience in the production of a self-perception of their own ,global identity'. In particular, attention is focused on the structures and social spaces of everyday life in five crucial occupations (corporate managers, financial services workers, artists, media professionals and schoolteachers) where people's professional action is performed simultaneously along local and global axes. Within these groups the globalized self does not merely reflect individuals' engagement in transnational networks, but is also the outcome of a complex process including two added dimensions of social life in the job setting: (1) the degree and type of non-filtered exposure to pressures stemming from the global environment, which both constrain and enable subjective practices of coping with change and ambiguity; and (2) the degree and type of competence in the rhetorics of globalization, namely the level of access to well-known repertoires of interpretive resources for making sense of global trends. This analysis is consistent with social science conceptualizations arguing for a more nuanced understanding of globalization. In this light, not only is globalization a multidimensional process but it also produces a variety of responses and meanings by differently positioned actors. [source] Working parents with young children: cross-national comparisons of policies and programmes in three countriesINTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 4 2003Susan F. AllenArticle first published online: 10 OCT 200 Multiple global trends are putting pressure on governments to develop policies and programmes that meet the needs of families with children aged 0,3. This cross-national analysis focuses on policies and programmes of parental leave and childcare in the United States, Sweden and Japan. Cross-national studies of early childhood education and care are reviewed. National profiles are provided of demographic, economic, political and socio-cultural characteristics and of parental leave and childcare policies and programmes. Policies and programmes are compared in relation to equity of coverage and support of basic parental childrearing and child-protection responsibilities. Issues raised highlight the need for unified programmes and policies, and continuing global dialogue regarding the needs of this population. [source] Report from the 1st Japanese Urological Association-Japanese Society of Medical Oncology joint conference, 2006: ,A step towards better collaboration between urologists and medical oncologists'INTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2007Hideyuki Akaza Abstract: The 1st Japanese Urological Association,Japanese Society of Medical Oncology Joint Conference, titled ,A step towards better collaboration between urologists and medical oncologists', was held to coincide with the 44th Meeting of the Japan Society of Clinical Oncology, Tokyo, in October 2006. The main theme of the conference addressed the need for a subspecialty of medical oncologist within urology to keep abreast of advances in medical oncology. Urologists should become more involved in the postoperative management of urologic cancer. Consensus on the optimal way to move forward in the treatment of urological cancer is needed. The conference featured eight lectures surveying the present status of uro-oncology in Europe, the USA, Korea, Singapore, and Japan; the relationship between surgical oncologists and medical oncologists; global trends and international clinical trials in uro-oncology; and the future of urologic oncology. These were followed by a general discussion titled ,Achieving better collaboration between the surgical oncologist and the medical oncologist.' This report presents a roundup of the 1st Japanese Urological Association,Japanese Society of Medical Oncology Joint Conference. [source] Biotic diachroneity during the Ordovician Radiation: evidence from South ChinaLETHAIA, Issue 3 2006Renbin Zhan The Ordovician radiation was one of the most marked and sustained increases in Phanerozoic biodiversification; nevertheless it occurred against a background of minimal global climatic and environmental perturbations. Detailed investigations of the Ordovician successions on the Yangtze Platform of the South China palaeoplate indicate that: (1) the brachiopod ,- and ,-diversity changes are diachronous; (2) macroevolutionary patterns were different across the South China palaeoplate, with the Early Ordovician brachiopod radiation first occurring in normal marine, shallow-water environments and then moving gradually to both nearer-shore and offshore locations; (3) the main contributors to the initial Ordovician brachiopod radiation were the Orthida and Pentamerida; the typical Ordovician brachiopod fauna, dominated by the Orthida and Strophomenida, did not appear until the late Mid Ordovician (Undulograptus austrodentatus Biozone) when the Strophomenida apparently replaced the dominant position of the Pentamerida within the fauna; (4) different ecotypes (e.g., sessile benthos, mobile benthos together with pelagic and planktonic organisms) demonstrate substantially different macroevolutionary patterns. The Ordovician brachiopod radiation of South China was apparently earlier than that suggested by global trends together with the data available from other palaeoplates or terranes, which may be related to its unique palaeogeographic position (peri-Gondwanan terrane gradually moving to equatorial latitudes). [source] Secular trend in medical education regarding infectious diseaseMEDICAL EDUCATION, Issue 10 2003Kai Ming Chow Objective ,The paradigm of global medical health has been re-characterised by a shift in its major focus from infectious disease to chronic illness. Opinions vary as to the declining emphasis on infectious disease. This paper provides clinicians with an understanding of a secular trend in medical education regarding the topic of infectious diseases over a period of 26 years. Methods ,A survey was carried out to evaluate coverage of infectious disease topics within recent general medicine textbooks and journals. Results ,The percentage of content dedicated to infectious disease has remained static in 2 major medical textbooks, whereas a trend towards decreasing coverage was shown in 4 major medical journals. Of 901 original articles published in 2000, 16·4% covered certain aspects of infectious disease, as compared with 20·9% of 790 articles published in 1985. Increasing rates of infectious disease mortality in developing countries were not consistently matched with the trend in coverage of infectious disease topics in either medical textbooks or journals. Conclusions ,Our data demonstrate that coverage of infectious disease topics in publications issued in developed countries was more indicative of global trends in disease mortality rather than those of developing countries. Medical education and knowledge, which are usually delivered by the rich nations where influential medical textbooks and journals are published, place less emphasis on infectious disease relative to the burden infectious disease places on the developing world. [source] New paradigms for the future: keynote perspectives from The R&D Management Conference 2008R & D MANAGEMENT, Issue 1 2010Flavia Leung The R&D Management Conference 2008 theme of ,emerging and new approaches to R&D management' sought to draw out how R&D-based organizations today are changing the way they manage (in terms of novel approaches, techniques, models and tools) in face of the challenges and opportunities presented in the current environment. Six keynote presentations by executives, representing both the public and private sectors, elaborated on the following subjects reflecting their experiences on the theme: hyperconnectivity and changing R&D tenets, accelerating discoveries in human health via open access public-private partnerships, role of government in bridging the innovation gap, building sustainability and innovation in a traditional resource sector, R&D management in the aerospace sector, and leveraging diversity to build a culture of innovation. Their presentations highlighted amongst other things , global trends that are affecting how R&D organizations are operating, economic imperatives driving change in business models, working through partnerships within an open innovation environment, and leveraging the diversity presented by an increasingly globalized R&D workforce for success. Within these presentations are also challenges to researchers to generate new thinking to address current and future problems presented by the R&D environment. The keynote perspectives are summarized in this paper. [source] A family business: Women, children and smallholder sugar cane farming in FijiASIA PACIFIC VIEWPOINT, Issue 2 2003Sue Carswell Abstract: This paper highlights the contribution of women and children to the sugar industry in Fiji by examining the importance of family labour in the historical development of the smallholder system and describing the present situation for the study participants. It is based on ethnographic fieldwork conducted during 1996,97, on the island of Vanua Levu in the northern region of Fiji. The twenty smallholder households in the study comprised both Fijian and Fiji Indian respondents who relied primarily on selling sugar cane for their cash income. How inequalities within the household in terms of allocation of labour and resources are legitimated is outlined. Resource distribution within the household in regards to two important issues for the sugar industry, land and trade liberalisation, are examined. In light of global trends in trade liberalisation and probable falls in sugar prices, future strategies for survival identified by Fijian and Fiji Indian smallholders are also discussed. The case study demonstrates that the sugar industry is still largely reliant on family labour and, particularly for low socio-economic smallholders, the unremunerated labour of family members makes an essential contribution to the production of sugar cane.
