Much of the worlds biodiversity is located within countries with developing economies. We therefore examine how well developing nations and their scientists are represented in three international conservation biology journals (Conservation Biology, Biological Conservation, Biodiversity and Conservation). We found: (1) that 28% of studies were from lower income countries and only 15% of all papers had primary authors from these nations. Of papers from lower income countries, although 80% had at least one local author, only 47% had primary authors from the country where the study was conducted. (2) Lower income countries had more research with a strong applied focus compared to research from high-income countries. (3) In lower income countries research was often funded by international sources but the primary authors of these studies were from affluent nations. (4) The three journals differed in how well they represented lower income nations and their scientists, reflecting their editorial policies for including research from lower income nations. The main reason for the large discrepancy in a countrys output of conservation research is due to the difference in a nations ability to invest in science. However, a brief survey of authors suggests that there is a large amount of information available in lower income and non-English speaking countries that is not easily accessible to the international conservation community. Journals may therefore need to consider altering their policies if we are to improve the representation of research by scientists in lower income nations.  相似文献

The discipline of modern "risk factor" epidemiology was in its formative stages in the early 1950s, when epidemiologic studies revealed a strong association between cigarette smoking and lung cancer mortality. Many medical scientists and physicians were reluctant to accept these studies as a demonstration of causation because the methods were "statistical" and involved data collected in uncontrolled conditions outside the laboratory. But a substantial number of senior biostatisticians and epidemiologists also voiced concerns, albeit more methodologically sophisticated, about the quality of the evidence at the time. Statistical methods were just beginning to work their way into medicine and public health, and many epidemiologists and statisticians were concerned about the potential misuse of these methods by untrained investigators. When studies of smoking and lung cancer gained increasing publicity and were being used to recommend public health policies, some prominent epidemiologists and statisticians highlighted this debate in their efforts to pursue methodological reform. Participants in the debate over smoking and lung cancer saw the need for explicit and rigorous standards for evaluating etiologic hypotheses, but they held conflicting views about what those standards should be. These diverging views reflect an underlying tension within the discipline of epidemiology between the search for "objective" methods of scientific inference and the practical needs of public health research that persists today.  相似文献

In this article, we investigate the delicacy of adopting pronatalism as a public position in Italy. Mounting scientific and political knowledge about the demographic "problem" exposes a new hegemonic formation that low fertility is dangerous. Drawing on ethnographic contexts, political debates, media publications, and policy documents, we trace the "demographic emergency" and compare two policies: a monetary baby bonus and a law restricting assisted reproduction. The coexistence of incentives to counter superlow fertility with prohibitions on high-tech baby making reflect the contested governance of "social cohesion." We conclude that scholarly and popular discourses serve as a sort of "social Viagra." Ultimately, both policies sought to rejuvenate family norms. Both aimed to fortify the political terrain of a nation-state struggling to achieve and maintain modernity against a backdrop of immigration and aging. Modernity became a weapon of the state to exert control over Italian fertility practices and of its critics to deploy orientalizing representations of backwardness.  相似文献

Although the international community has taken some steps to address the risks created by the movements of ultrahazardous radioactive cargoes, important gaps still exist in the legal regime governing these activities. An apparent consensus has been reached at the International Maritime Organization (IMO) to make the Code for the Safe Carriage of Irradiated Nuclear Fuel, Plutonium, and High-Level Radioactive Wastes in Flasks Aboard Ships (the INF Code) mandatory and to seek some clarification of the standards governing shipboard safety. But still lacking are agreements regarding salvage responsibilities, liability of shippers for damages, revision of transport cask safety standards to meet maritime accident conditions, obligations to consult regarding the best routes and to provide advance notification to concerned coastal states, the preparation of environmental assessments, and contingency planning to handle shore emergencies and salvage responsibilities. Until agreements are reached on these important matters, the shipment of these extremely dangerous or "ultrahazardous" materials will continue to violate fundamental norms of international law and comity because they place coastal nations that receive no benefit from the shipments at grave risk of environmental disaster without any legal protections. Because the shipments of ultrahazardous radioactive cargoes are increasing, it is highly advisable for concerned nations to negotiate regional protocols delineating the legal regime that applies to these maritime transports. A draft model protocol is attached at the end of this article which may provide guidance on this effort. It is also appropriate for concerned nations to consider bringing a claim against the shipping nations under the dispute resolution mechanisms established by the 1982 United Nations Law of the Sea Convention. Such a claim would be based on the failure of the shipping nations to comply with their obligations under the convention to prepare and distribute environmental impact assessments, consult with affected nations, prepare emergency contingency plans, and agree to an effective liability regime in the event of an accident. Because of the grave potential risks created by these shipments and because of the failure of the shippers to meet their obligations to protect coastal nations from these risks, coastal nations may be justified under international law to take unilateral or regional action to block future shipments.  相似文献

The susceptibility of American cockroaches, Periplaneta americana (L.); smoky brown cockroaches, P. fuliginosa (Serville); oriental cockroaches, Blatta orientalis L.; German cockroaches, Blattella germanica (L.); and brownbanded cockroaches, Supella longipalpa (F.), to Steinernema carpocapsae Weiser (All strain) was evaluated under laboratory conditions. A 1-ml water suspension containing 500,000 nematodes was placed on filter paper in a petri dish or the pad of a bait station. German, brown-banded, oriental, and smoky-brown cockroaches died within 1 d after placement in the petri dishes. The relative order for the LT50s were American greater than oriental greater than smoky-brown greater than brown-banded = German. All cockroaches actively groomed nematodes from legs and antennae of forced (petri dish) exposure. The LT50s for S. carpocapsae for nonforced (bait station) exposure were significantly greater than those for forced exposure. The LT50s were 3.25, 4.13, 9.86, and 11.38 d for brown-banded, German, oriental, and smoky-brown cockroaches, respectively. The relative order of the LT50s after forced (American greater than oriental greater than smoky-brown greater than German = brown-banded) and nonforced (American greater than smoky-brown greater than oriental greater than German greater than brown-banded) exposure to S. carpocapsae was inversely related to the moisture of their preferred habitats.  相似文献

Throughout Western societies, policy‐makers who address the problems of disadvantaged ethnic and immigrant minorities confront norms that prescribe equal or preferential treatment for these groups. Variations in these norms make significant differences in policy‐making. Based on evidence from housing and planning policies and a standardized survey of local élites in comparable German, French and US metropolitan areas, this article analyses how these norms altered logics of policy‐making. Normative differences help to explain why policies to house minorities proved more successful in the German setting than in the French. Contrasts in central‐local relations, in local government, in political parties and in the social and economic background of policy‐making fail to account for the difference that these norms make. In the American setting normative ambiguities combined with institutional, social and spatial differences to render parallel norms comparatively ineffective.  相似文献

In this article, we examine the shifting policies of sending country states towards communities living abroad, demonstrate the ways in which these are redefining the relationship between the state and its territorial boundaries, and highlight how these reconfigure conventional understandings of sovereignty, citizenship and membership. We begin by delineating the ­different types of policies that sending states are adapting in order to break down categories like "global nations policies" and to identify similarities and differences between states. We then suggest some possible explanations both for the convergence we see on the "repertoire" of policies that states employ and divergence we see in how far states are willing to go to ensure that migrants remain enduring long-distance membership. We draw on material from several countries, but look most closely at Brazil, Mexico, the Dominican Republic and Haiti.  相似文献

When it comes to interpreting others'' behaviour, we almost irrepressibly engage in the attribution of mental states (beliefs, emotions…). Such "mentalizing" can become very sophisticated, eventually endowing us with highly adaptive skills such as convincing, teaching or deceiving. Here, sophistication can be captured in terms of the depth of our recursive beliefs, as in "I think that you think that I think…" In this work, we test whether such sophisticated recursive beliefs subtend learning in the context of social interaction. We asked participants to play repeated games against artificial (Bayesian) mentalizing agents, which differ in their sophistication. Critically, we made people believe either that they were playing against each other, or that they were gambling like in a casino. Although both framings are similarly deceiving, participants win against the artificial (sophisticated) mentalizing agents in the social framing of the task, and lose in the non-social framing. Moreover, we find that participants'' choice sequences are best explained by sophisticated mentalizing Bayesian learning models only in the social framing. This study is the first demonstration of the added-value of mentalizing on learning in the context of repeated social interactions. Importantly, our results show that we would not be able to decipher intentional behaviour without a priori attributing mental states to others.  相似文献

This article explores the complex and contradictory experiences of urban American Indian drinkers. While previous anthropological accounts have emphasized the functions served by American Indian drinking, the testimony of drinkers also documents their awareness of the destructive effects of heavy drinking, particularly the way in which it often interferes with their ability to meet social obligations. Nevertheless, people often continue to use alcohol, and this means that many are profoundly ambivalent about their drinking; they see it simultaneously as something that is embedded in certain important relationships, but also something that is destructive of much that they value. Drawing on interviews with 35 self-defined problem drinkers, this article details the ambiguous nature of the American Indian experience with alcohol, highlighting the need for clinically sophisticated anthropology of alcohol, [alcohol, American Indians, functional ism, clinical approaches]  相似文献

Summary Two isolates of Pleurotus ostreatus from North America and one from Germany are interbreedable. Under identical conditions at low temperatures, their fruiting bodies are hard to distinguish. However, shape and colour and several other characters vary with culture conditions. The American stocks fruit well at temperatures from 4 to 24 °C, the German ones only below 15 °C. Four types of hybrids between German and American Pleupotus were obtained: i) The whole fruiting process is temperature sensitive as in German Pleurotus. ii) It proceeds at 4–24 °C as in American stocks, iii) Fruiting initiation is insensitive but sporophore development is sensitive to elevated temperatures, iv) Primordia formation and initial sporophore development depend on temperatures below 15 °C, but pileus expansion and spore discharge continue above 20 °. The involvement of separate genes for the single developmental steps and the use of temperature sensitivity for commercial varieties are discussed. One sporeless strain, F42x11, with considerable fruiting bodies has been obtained. In intrastock di-mon-matings this character was dominant.  相似文献

Recently, in increasing numbers, citizens of wealthy nations are heading to poorer countries for medical care. They are traveling to the global South as medical tourists because in their home nations either they cannot get timely medical care or they cannot afford needed treatments. This essay offers a robust, particularist ethical assessment of the practice of citizens of richer nations traveling to poorer countries for healthcare.  相似文献

The predator-prey relationship between California ground squirrels (Spermophilus beecheyi) and northern Pacific rattlesnakes (Crotalus viridis) is a useful system for exploring conflict and assessment. Rattlesnakes are major predators of ground squirrel pups, but pose a less significant threat to adult squirrels. Adults approach, harass, and even attack rattlesnakes in defense of their pups. Two factors that may influence risk to both squirrel and snake during encounters are the size and body temperature of the rattlesnake. We used high-speed video to analyze the strikes of rattlesnakes of various sizes tested at different body temperatures. Results indicate that warmer snakes are more dangerous because they strike with higher velocity, greater accuracy, and less hesitation. Similarly, larger snakes are more dangerous because they can strike farther and at higher speeds, and keep their fangs embedded longer. Thus, ground squirrels would benefit from extracting information about a rattlesnake's size and temperature. The converse of our results is that cooler, smaller rattlesnakes may be more vulnerable. These snakes could mitigate their risk by avoiding dangerous adversaries and minimizing cues that divulge their weaknesses. Such tactics might explain the active probing that squirrels direct at rattlesnakes, which may function to overcome a snake's resistance to disclosing its vulnerability.  相似文献

Anthropologists have begun to publish ethnographic accounts of policy-making, but few have studied medical or health matters, despite broad acceptance in anthropology that "biopower" permeates contemporary societies. This article presents some findings from an ethnographic study of how diabetes gained recognition as a pressing public health problem in Canada. It underlines the importance of statistics for constituting power within and across nation states. Statistics imbricate people and things distributed across vast distances, but they still need to be generated and invoked by individuals to engender effects--as illustrated in this article by the contributions of researchers, aboriginal leaders, and an American actress, Mary Tyler Moore--in this case, the development of Canadian government policies justified in the name of averting and controlling diabetes. To make sense of these findings, subtle differences between two concepts coined by Michel Foucault, "biopower" and "governmentality," seem significant.  相似文献

This paper discusses the economic, legal, moral, and political difficulties in developing drugs for the developing world. It argues that large, global pharmaceutical companies have social responsibilities to the developing world, and that they may exercise these responsibilities by investing in research and development related to diseases that affect developing nations, offering discounts on drug prices, and initiating drug giveaways. However, these social responsibilities are not absolute requirements and may be balanced against other obligations and commitments in light of economic, social, legal, political, and other conditions. How a company decides to exercise its social responsibilities to the developing world depends on (1) the prospects for a reasonable profit and (2) the prospects for a productive business environment. Developing nations can either help or hinder the pharmaceutical industry's efforts to exercise social responsibility through various policies and practices. To insure that companies can make a reasonable profit, developing nations should honor pharmaceutical product patents and adhere to international intellectual property treaties, such as the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement. To insure the companies have a good business environment, developing nations should try to promote the rule of law, ethical business practices, stable currencies, reliable banking systems, free and open markets, democracy, and other conditions conducive to business. Overall, this paper advocates for reciprocity and cooperation between pharmaceutical companies and developing nations to address the problem of developing drugs for the developing world. In pursuing this cooperative approach, developing nations may use a variety of other techniques to encourage pharmaceutical companies to act responsibly, such as subsidizing pharmaceutical research, helping to design and implement research protocols, providing a guaranteed market, and bulk buying.  相似文献

This paper is on dangerous human experimentations with drugs against trypanosimiasis carried out in the former German colonies of German East Africa and Togo. Victory over trypanosomiasis could not be achieved in Berlin because animals were thought to be unsuitable for therapeutic laboratory research in the field of trypanosomiasis. The colonies themselves were necessarily chosen as laboratories and the patients with sleeping sickness became the objects of therapeutical and pharmacological research. The paper first outlines Robert Koch's trypanosomiasis research in the large sleeping sickness laboratory of German East Africa and then focuses on the escalating human experiments on trypanosomiasis in the German Musterkolonie Togo, which must be interpreted as a reaction to the starting signal given by Robert Koch in East Africa.  相似文献

The toxicity of fatty acid salts to German, Blattella germanica (L.), and American cockroaches, Periplaneta americana (L.), was evaluated. Potassium and sodium laurate caused up to 95% mortality of German cockroaches and 100% mortality of American cockroaches. Even-numbered potassium fatty acid salts, C8-C18 were assessed for toxicity at 0.125, 0.25, 0.5, 1, and 2% concentrations by a 30-s immersion of cockroaches. The more soluble of the fatty acid salts at 2% concentration caused 65-95% mortality of German cockroaches and 100% mortality of American cockroaches. Potassium oleate, C18, was most toxic to both German (LC50 = 0.36%) and American (LC50 = 0.17%) cockroaches. Fatty acid salt solutions on a substrate were tested by placing cockroaches in contact with treated floor tiles immediately after application (wet) or after the solutions had dried. Sodium laurate and potassium caprate caused mortality of German (62 +/- 17.4 and 58 +/- 12.6%, respectively) and American cockroaches (52 +/- 18.5 and 28 +/- 4.9%, respectively) on wet tiles, whereas potassium oleate caused mortality of German cockroaches (67 +/- 14.1%) only. Dry fatty acids caused no mortality among exposed cockroaches. Fatty acid salt solutions can be effective in killing German and American cockroaches but only when insects are thoroughly wetted with 1-2% fatty acid salt solutions.  相似文献

Rituals that defuse immediate senses of danger can perpetuate senses of powerlessness. Ambiguous language used in defensive rituals can heighten people's senses of the risks they are confronting and also compel people to perform those rituals again in the future. In this article, I illustrate this argument by examining Fijian Methodist masu sema (chain prayers), which are conducted to defuse the dangers that beset society, including curses from demonic ancestors. I argue that Fijian cultural themes of present-day human powerlessness are generated largely by competition between Methodist and chiefly authorities. "Chain prayers" are attempts to negate the power of dangerous ancestors, but in requesting God's help, ritual participants cast themselves as powerless. Verbal ambiguity in chain prayers gives "demons" lives of their own, compelling their future circulation.  相似文献

This article offers a theoretical explanation for relationships between social status and involvement in serious and persistent criminal behavior from an evolutionary perspective. The theory's central premise is that natural selection has produced females who bias their mating choices toward males who strive for status. This bias has resulted in males devoting greater time and energy to status striving (relative to females). To account for why nearly all "victimizing" forms of criminality are more common among males than among females, the theory asserts that status striving exists along a continuum of competitive/victimizing behavior. One end of this continuum is epitomized by crude (criminal) forms of the behavior that societies generally discourage and even punish. The other end consists of sophisticated (commercial) forms that societies tolerate and even encourage. According to the theory, most males begin to exhibit non-playful forms of competitive/victimizing behavior around the onset of puberty as they start their reproductive careers. Adolescent males with the greatest abilities to learn will transition quickly from crude forms of competitive/victimizing behavior to more sophisticated forms, while males who have the greatest difficulties learning will transition more slowly. A major deduction from the theory is that genes on the Y-chromosome must be affecting the brain in ways that promote status-striving behavior. This deduction needs empirical scrutiny, although it is consistent with evidence (a) that the Y-chromosome transforms would-be ovaries into testes, the latter being specialized organs for the production of testosterone, and (b) that testosterone alters brain functioning in ways that contribute to both status striving and criminality.  相似文献

Based on ethnographic research regarding public policy and grassroots organizing for midwifery in Virginia, this article explores how medical discourses around appropriate health care practices intersect with state discourses about what practices are considered "respectable" versus "pathological" for its citizens. In recent legislative debates about the legalization of direct-entry midwifery, medical officials have extended their criticism of midwifery and homebirth to mothers who resist state-sanctioned childbirth practices. This article examines how medical officials challenge the respectable mothering practices of homebirthers by linking them with women they deem pathological--child abusers, negligent mothers, and drug users--and placing them outside the cadre of "normal" American mothers who acknowledge the "logical" and "natural" superiority of biomedical childbirth practices. I also address homebirth mothers' responses, which assert that their political advocacy for midwives is a respectable mothering practice because they are responsible citizens who desire what they deem the best care for their children.  相似文献

Cockroach allergy is a widespread health problem in the world, associated with the development of asthma. The German and American cockroach species are important producers of a wide variety of allergens. Knowledge of their structure and function contributes to understand their role in allergy and to design tools for diagnosis and immunotherapy.  相似文献
