Selected AbstractsCombined effects of two stressors on Kenyan coral reefs are additive or antagonistic, not synergisticCONSERVATION LETTERS, Issue 2 2010Emily S. Darling Abstract A challenge for conservation science is predicting the impacts of co-occurring human activities on ecological systems. Multiple anthropogenic and natural stressors impact ecosystems globally and are expected to jeopardize their ecological functions and the success of conservation and management initiatives. The possibility that two or more stressors interact synergistically is of particular concern, but such nonadditive effects remain largely unidentified in nature. A long-term data set of hard coral cover from Kenyan reefs was used to examine the independent and interactive effects of two stressors: fishing and a temperature anomaly in 1998 that caused mass coral bleaching and mortality. While both stressors decreased coral cover, fishing by 51% and bleaching by 74%, they did not interact synergistically. Instead, their combined effect was antagonistic or weakly additive. The observed nonsynergistic response may be caused by the presence of one dominant stressor, bleaching, and cotolerance of coral taxa to both bleaching and fishing stressors. Consequently, coral bleaching has been the dominant driver of coral loss on Kenyan reefs and while marine reserves offer many benefits to reef ecosystems, they may not provide corals with a refuge from climate change. [source] THE GOOD, THE BAD AND THE UGLY: ECONOMIC PERSPECTIVES ON REGULATION IN AUSTRALIAECONOMIC PAPERS: A JOURNAL OF APPLIED ECONOMICS AND POLICY, Issue 1 2004Gary Banks Chairman The paper examines the existing scope and role of regulations in Australia. While there are many benefits from regulation, there is also a myriad of, often underplayed, costs associated with regulations. While compliance costs are large, probably the most significant costs arise from behavioural responses to regulations that reduce efficiency or compromise social goals. These adverse effects are often unanticipated and arise from complex interactions between regulations. The main reasons for regulatory failure are excessive ambition (underestimating the deficiencies of the regulatory ,solution'), capture of regulatory agencies, and poor regulatory processes and institutions. The paper offers some guidelines for producing better regulation. [source] Organochlorine contaminants in sea turtles: Correlations between whole blood and fatENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 3 2004Jennifer M. Keller Abstract Monitoring toxic organochlorine(OC)compounds is an important aspect in wildlife studies, especially in protected species such as sea turtles. The goal of this study was to determine whether blood OC concentrations can predict those in adipose tissue of sea turtles. Blood offers many benefits for monitoring OCs. It can be collected nondestructively from live turtles and can be sampled repeatedly for continuous monitoring. Organochlorine concentrations in blood may better represent the exposure levels of target tissues, but blood concentrations may fluctuate more than those in fatty tissues following recent dietary exposure or lipid mobilization. Paired fat and blood samples were collected from 44 live, juvenile loggerhead sea turtles and 10 juvenile Kemp's ridley sea turtle carcasses. Organochlorines were analyzed using gas chromatography with electron capture detection and mass spectrometry. Lipid-normalized OC concentrations measured in the blood significantly correlated to levels found in the fat samples of both species. This result suggests that sea turtle blood is a suitable alternative to fatty tissues for measuring OCs because blood concentrations reasonably represent those observed in the paired fat samples. However, blood OC concentrations calculated on a wet-mass basis were significantly and inversely correlated to lipid content in the fat samples. Therefore, caution should be used when monitoring spatial or temporal trends, as OC levels may increase in the blood following mobilization of fat stores, such as during long migrations, breeding, or disease events. [source] International Portfolio Investment: Theory, Evidence, and Institutional FrameworkFINANCIAL MARKETS, INSTITUTIONS & INSTRUMENTS, Issue 3 2001Söhnke M. Bartram At first sight, the idea of investing internationally seems exciting and full of promise because of the many benefits of international portfolio investment. By investing in foreign securities, investors can participate in the growth of other countries, hedge their consumption basket against exchange rate risk, realize diversification effects and take advantage of market segmentation on a global scale. Even though these advantages might appear attractive, the risks of and constraints for international portfolio investment must not be overlooked. In an international context, financial investments are not only subject to currency risk and political risk, but there are many institutional constraints and barriers, significant among them a host of tax issues. These constraints, while being reduced by technology and policy, support the case for internationally segmented securities markets, with concomitant benefits for those who manage to overcome the barriers in an effective manner. [source] Systemic Immunization with Unadjuvanted Whole Helicobacter pylori Protects Mice Against Heterologous ChallengeHELICOBACTER, Issue 6 2008Stacey N. Harbour Abstract Background:, Adjuvant-free vaccines have many benefits, including decreased cost and toxicity. We examined the protective effect of systemic vaccination with adjuvant-free formalin-fixed Helicobacter pylori or bacterial lysate and the ability of this vaccine to induce protection against heterologous challenge. Materials and Methods:, Mice were vaccinated subcutaneously with H. pylori 11637 lysate or formalin-fixed bacteria, with or without ISCOMATRIXTM adjuvant, then orally challenged with H. pylori SS1. Serum was taken prior to challenge to examine specific antibody levels induced by the vaccinations, and protection was assessed by colony-forming assay. Results:, Vaccination with H. pylori 11637 lysate or formalin-fixed bacteria delivered systemically induced significantly higher levels of Helicobacter -specific serum IgG than the control, unvaccinated group and orally vaccinated group. After heterologous challenge with H. pylori SS1, all vaccinated groups had significantly lower levels of colonization compared with unvaccinated, control mice, regardless of the addition of adjuvant or route of delivery. Protection induced by systemic vaccination with whole bacterial preparations, without the addition of adjuvants, was only associated with a mild cellular infiltration into the gastric mucosa, with no evidence of atrophy. Conclusions:, Subcutaneous vaccination using unadjuvanted formalin-fixed H. pylori has the potential to be a simple, cost-effective approach to the development of a Helicobacter vaccine. Importantly, this vaccine was able to induce protection against heterologous challenge, a factor that would be crucial in any human Helicobacter vaccine. Further studies are required to determine mechanisms of protection and to improve protective ability. [source] Temporary Employment and Strategic Staffing in the Manufacturing SectorINDUSTRIAL RELATIONS, Issue 1 2009MATT VIDAL While prior research has identified different ways of using temporary workers to achieve numerical flexibility, quantitative analysis of temporary employment has been limited to a few key empirical indicators of demand variability that may confound important differences. Our analysis provides evidence that many manufacturers use temporary workers to achieve what we call planned and systematic numerical flexibility rather than simply in a reactive manner to deal with unexpected problems. Although temporary work may provide many benefits for employers, a key function appears to be the provision of numerical flexibility not to buffer core workers but to externalize certain jobs. [source] Implicit Theories of Organizational Power and Priming Effects on Managerial Power-Sharing Decisions: An Experimental Study,JOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 2 2004Peter T. Coleman Over 60 years of research on participative leadership has documented the many benefits of power sharing in organizations. However, a common obstacle to power sharing is the unwillingness of those with power to share it. An experimental study is presented that investigated the effects of managers' implicit theories of power in organizations on their willingness to share power with subordinates. The study proposed that chronic differences in implicit power theories (the degree of competitive vs. cooperative beliefs and ideals regarding organizational power relations) would affect managers' decisions to share or withhold power. Subliminal priming was predicted to temporarily enhance the accessibility of these differences in implicit power theories, thereby fostering or inhibiting spontaneous decisions to share power. Results indicate that the subliminal priming of competitive theories of organizational power negatively influenced managers' immediate, spontaneous decisions to share power, whereas chronic differences in their implicit theories similarly affected their more systematic decisions to share power. The theoretical and applied contributions of the study are discussed. [source] Farmers' perception of treated paper mill effluent irrigationLAND DEGRADATION AND DEVELOPMENT, Issue 3 2010P. N. Rekha Abstract The utilization of treated paper mill effluents for irrigation offers many benefits such as conservation of water resources, conversion of barren land into irrigated area, addition of nutrients to the soil and plant and above all the reduction of pollution of inland water bodies. However, the utility of this effluent irrigation programme depends mainly on farmers' acceptability, adoption and management of the scheme. Knowledge about the farmers' perception is thus very much imperative for further advocacy of the effluent irrigation programme. The determinants of farmers' perception of treated paper mill effluent irrigation is a pre-requisite for the formulation of better programmes and strategies for the support of an unobstructed adoption and for the long-term sustainability of effluent irrigation schemes. The present study was conducted to assess the farmers' perception and the determinants that influence the adoption of treated paper mill effluent irrigation by interviewing a random sample of 120 farmers, using a well-structured interview schedule in paper mill effluent irrigated area in Tamil Nadu in India. The study revealed that there exists positive significant correlation between the perception and the characteristics of the farmers viz. educational status, farm size, annual income, mass media exposure, innovativeness and risk orientation. The response analysis of the perception revealed that treated paper mill effluent as alternative assured supply of irrigation water, conversion of elevated dry lands to irrigated land, changing of cropping pattern to sugarcane, increase in socioeconomic status of the farmers, incentives and technical inputs by the paper mill authorities and above all farmers' participation in planning, implementation and management of the effluent irrigation schemes influenced the farmers to form positive perception.

[source] College Football and Student Quality: An Advertising Effect or Culture and Tradition?AMERICAN JOURNAL OF ECONOMICS AND SOCIOLOGY, Issue 2 2009Article first published online: 9 APR 200, D. Randall Smith Intercollegiate sports are said to generate positive advertising that produces many benefits to the host school. Donations, applications, and the academic quality of the student body are some of the mission outcomes thought to rise with the fortunes of the football team. The present study tests these claims for three measures of the academic quality of the entering classes on a 12-year panel of the 233 colleges and universities competing at the highest levels of football. Results show clear positive effects attributable to the football program, though those effects are more the result of the football culture and tradition at the school than the on-field performance of the team. Any sports advertising effects of the football program are minimal when compared to the effects of nonathletic institutional characteristics on the quality of students enrolling at the school. [source] 1.,Globalization and Violence: The Challenge to EthicsAMERICAN JOURNAL OF ECONOMICS AND SOCIOLOGY, Issue 1 2009Edward Demenchonok Despite its many benefits, globalization has proven to harbor a good deal of violence. This is not only a matter of the proliferation of weapons of mass destruction inaugurated by the atomic bombing of Hiroshima, but includes many forms of indirect or "structural violence" resulting from the routine of economic and political institutions on the global scale. In this essay, the multifaceted phenomena of violence are approached from the standpoint of ethics. The prevailing political thinking associated with "realism" fails to address the problems of militarism and of hegemonic unilateralism. In contrast, many philosophers are critically rethinking the problem of global violence from different ethical perspectives. Despite sharing similar concerns, philosophers nevertheless differ over the role of philosophical reflection and the potentials of reason. These differences appear in two contrasting approaches associated with postmodern philosophy and discourse ethics. In the analysis of discourse ethics, attention is paid to Karl-Otto Apel's attempt of philosophically grounding a macroethics of planetary co-responsibility. At the heart of the essay is the analysis of the problem of violence, including terrorism, by Jürgen Habermas, who explains the phenomenon of violence in terms of the theory of communicative action as the breakdown of communication. Jacques Derrida's deconstruction of the notion of "terrorism" also is analyzed. According to the principle of discourse ethics, all conflicts between human beings ought to be settled in a way free of violence, through discourses and negotiations. These philosophers conclude that the reliance on force does not solve social and global problems, including those that are the source of violence. The only viable alternative is the "dialogical" multilateral relations of peaceful coexistence and cooperation among the nations for solving social and global problems. They emphasize the necessity of strengthening the international rule of law and institutions, such as a reformed United Nations.

The case illustrates two valuable points of interest: the many benefits of regional anesthesia in complex medical cases and the successful use of tourniquets in children with sickle cell disease. [source] Pesticide use in ornamental production: what are the benefits?PEST MANAGEMENT SCIENCE (FORMERLY: PESTICIDE SCIENCE), Issue 4 2009James A Bethke Abstract Pest control in ornamental production is challenging owing to the diversity of crops grown, the desired aesthetic perfection, the potential economic loss due to failure and the multitude of arthropod pests encountered. Agricultural crops of less value per acre, such as row crops, can tolerate a certain level of damage from arthropod pests without compromising yields. Damage thresholds for ornamentals, however, are essentially zero. Pesticides are a viable method of protection for such a crop in lieu of alternatives. Therefore, the purpose of this paper is to emphasize the importance of pesticides to the ornamental industry. Pesticides provide many benefits to ornamental producers, including: (1) consistent availability; (2) rapid kill; (3) reliable and consistent control; (4) increased crop production and quality; (5) they may be used to prevent movement of invasive pests; (6) they are less expensive (in general) than alternatives; (7) they may reduce plant pathogenic transmission; (8) they may be used in conjunction with natural enemies. Pesticide use will continue to be a significant strategy for dealing with arthropod pests so that ornamental producers can stay competitive in both national and international markets.

Oliffe Abstract Objective: Many commentaries about men's health practices and masculinities indicate that men do not typically engage with self-health or acknowledge illness, let alone openly discuss their health concerns with other men. Prostate cancer support groups (PCSGs) appear to run contrary to such ideals, yet the factors that influence men's attendance and engagement at group meetings are poorly understood. As part of a larger PCSG study, we noticed that humor was central to many group interactions and this prompted us to examine the connections between humor, health, and masculinities. Methods: A qualitative ethnographic design was used to direct fieldwork and conduct participant observations at the meetings of 16 PCSGs in British Columbia, Canada. Individual semi-structured interviews were completed with 54 men who attended PCSGs to better understand their perceptions about the use of humor at group meetings. Results: Four themes, disarming stoicism, marking the boundaries, rekindling and reformulating men's sexuality, and when humor goes south were drawn from the analyses. Overall, humor was used to promote inclusiveness, mark the boundaries for providing and receiving mutual help, and develop masculine group norms around men's sexuality. Although there were many benefits to humor there were also some instances when well-intended banter caused discomfort for attendees. Conclusions: The importance of group leadership was central to preserving the benefits of humor, and the specificities of how humor is used at PCSGs may provide direction for clinical practice and the design of future community-based men's health promotion programs.

[source] Cyclic olefin homopolymer-based microfluidics for protein crystallization and in situ X-ray diffractionACTA CRYSTALLOGRAPHICA SECTION D, Issue 9 2009Soheila Emamzadah Microfluidics is a promising technology for the rapid identification of protein crystallization conditions. However, most of the existing systems utilize silicone elastomers as the chip material which, despite its many benefits, is highly permeable to water vapour. This limits the time available for protein crystallization to less than a week. Here, the use of a cyclic olefin homopolymer-based microfluidics system for protein crystallization and in situ X-ray diffraction is described. Liquid handling in this system is performed in 2,mm thin transparent cards which contain 500 chambers, each with a volume of 320,nl. Microbatch, vapour-diffusion and free-interface diffusion protocols for protein crystallization were implemented and crystals were obtained of a number of proteins, including chicken lysozyme, bovine trypsin, a human p53 protein containing both the DNA-binding and oligomerization domains bound to DNA and a functionally important domain of Arabidopsis Morpheus' molecule 1 (MOM1). The latter two polypeptides have not been crystallized previously. For X-ray diffraction analysis, either the cards were opened to allow mounting of the crystals on loops or the crystals were exposed to X-rays in situ. For lysozyme, an entire X-ray diffraction data set at 1.5,Å resolution was collected without removing the crystal from the card. Thus, cyclic olefin homopolymer-based microfluidics systems have the potential to further automate protein crystallization and structural genomics efforts. [source] Social Welfare Reform Since the 1997 Economic Crisis in Korea: Achievement, Limits, and Future ProspectsASIAN SOCIAL WORK AND POLICY REVIEW, Issue 1 2007Inhoe Ku Social welfare reform has been implemented in Korea since the 1997 financial crisis. A dominant concern of the reform was on equality and social solidarity. A major means to this end was establishing universalistic social insurance programs like those in developed welfare states. The reform efforts produced some positive results but were not greatly successful. Income polarization and the deteriorating economic status of low-income families have become big social issues. Many low-income families have not gained many benefits from the reformed social security system. The rapid aging of the population is creating an exploding demand for social spending, risking the fiscal sustainability of major social insurance programs. The reform experience suggests that a social welfare system based on western-style universal social insurance may be too expensive to sustain and not very effective in protecting disadvantaged families in Korea. More attention is being paid to expenditure control and efficiency. Social insurance programs may need to be leaner than those in traditional welfare states. Targeted programs, such as the "making work pay" policy, are likely to be expanded more broadly to low-income families. The future of the Korean welfare state may hinge on successful employment support for working families and extensive investment in their human capital. [source] A Model for Ultrasound-Assisted Lumbar PunctureACADEMIC EMERGENCY MEDICINE, Issue 2009Matthew Herron Clinicians may find traditional lumbar puncture (LP) attempts fail due to indistinct landmarks in morbidly obese patients necessitating ultrasound localization or fluoroscopy. We believe a readily available teaching model is needed because many emergency physicians may be unfamiliar with ultrasound-assisted LP. Review of current literature shows that there are few commercially available LP models suitable for use with ultrasound. Those on the market are expensive and have limited reusability. We have succeeded in creating a low-cost reusable model for training health care professionals to perform ultrasound-assisted LP. We believe there will be many benefits to using this model including: increase in emergency department (ED) LP success rates, decrease in number of radiology consults for fluoroscopy, increase in patient satisfaction, decreased waiting time in the ED, and fewer complications due to fewer needle passes. This model effectively reproduces the sonographic appearance of the lumbar spine and overlying soft tissue and aids in teaching bedside ultrasound-assisted LP. The model has an opaque "skin" overlying a gel wax mold containing a lumbar spine. A catheter containing water is imbedded in the spine to simulate the spinal canal and cerebrospinal fluid. The skin allows for a more realistic procedure and can be removed for visual confirmation of a successful LP. In addition, successful needle placement will result in return of clear fluid. Construction of the model requires a commercially available lumbar spine and items found in craft stores with a total cost of approximately $100. [source] Virtual education in universities: a technological imperativeBRITISH JOURNAL OF EDUCATIONAL TECHNOLOGY, Issue 5 2001John O'Donoghue Many educational journals have debated the issue of the "virtual university". As technology is improving and evolving, such "virtuality" becomes a reality. The forecasts are that, in the not too distant future, it will be possible for courses to be completed solely by the use of the World Wide Web or Internet. These "virtual classrooms" will take the place of the solid buildings where students currently attend lectures, at set times in set rooms. The information will be gathered at the student's convenience and assignments will be handed in via this medium. There is potentially an advantage for everyone involved, from the reduced building resource costs to the availability of teaching support 24 hours a day, 7 days a week Whilst many of these studies identify the benefits of technology in education there are dissenting voices from many other quarters. However there are also arguments identifying the disadvantages to the technology based delivery systems proposed. Either way, there are going to be radical changes in the methods which students will use to tackle the workload involved in studying towards a degree. This paper will explore both sides of the argument. The main contention of this paper is that technology undoubtedly will offer many benefits for the learner, however, the pitfalls need careful consideration in the design of the learning environment. This paper uses examples from educational institutions across different cultures. [source] Is laparoscopic surgery acceptable for advanced colon cancer?CANCER SCIENCE, Issue 4 2009Seigo Kitano Laparoscopic surgery is widespread in the treatment of colorectal cancer. In Japan, a nationwide survey has shown that the rate of advanced colorectal cancer has increased gradually to 65% of total laparoscopic surgeries in 2007. Many randomized controlled trials have demonstrated that in the short term, laparoscopic surgery is feasible, safe, and has many benefits, including reduction of peri-operative mortality. In terms of long-term outcomes, four randomized controlled trials suggest that there are no differences in laparosupic and open surgery for colon cancer. However, important issues, including long-term oncological outcome, cost effectiveness, and the impact on the quality of life of patients, should be addressed in well-designed large-scale trials. In Japan, a retrospective multicenter study has demonstrated that the short-term outcomes of laparoscopic surgery are beneficial, and the long-term outcomes are the same as for open surgery. In 2004, a prospective large-scale randomized controlled trial (JCOG0404) to compare laparoscopic surgery with open surgery was started to evaluate oncological outcomes for advanced colon cancer. This trial is supported in part by a Grant-in-Aid for Cancer Research from the Japanese Ministry of Health, Labour, and Welfare. In the present study, laparoscopic surgery is found to be acceptable for stage I disease of colon cancer, whereas it is controversial for stage II/III disease because of inadequate clinical evidence. Whether laparoscopic surgery is acceptable for advanced colon cancer or not should be confirmed by the Japanese large-scale prospective randomized controlled trial (JCOG0404) in the near future.
