Pesticides overuse is a serious threat to ecosystems and wildlife, human health, and agricultural sustainability. So far, however, social scientists have not produced systematic evidence on the political–economic determinants of pesticides overuse. We argue that the agrochemical industry, as a profit‐motivated interest group, will only mobilize politically to avoid reductions in pesticides use when regulatory institutions are potentially capable of correcting a market failure. If regulatory institutions are weakened by corruption or other factors, pesticides overuse occurs with or without the influence of the agrochemical industry. We test this interactive theory systematically against quantitative data on pesticides use in 24 Organisation for Economic Co‐operation and Development countries, 1991–2003. Using corruption and other indicators to capture bureaucratic quality, we find substantively large and statistically robust interactive effects. The agrochemical industry is a crucial determinant of pesticides use in nations with low corruption, whereas the agrochemical industry has no effect on pesticides use under corrupt regulatory institutions. Troublingly, these results imply that reduced corruption may not improve actual regulatory effectiveness unless political institutions can somehow constrain the influence of special interests. 相似文献

Autosomal STR typing alone seems to be no sufficient tool for resolving deficiency cases (e.g. cases of questioned paternity or half-sibships). Therefore, we investigated whether the additional analysis of RFLP single locus probes can improve the solution of such complicated kinship cases. We analyzed 207 children and men from 101 families using the AmpFlSTRIdentifiler multiplex PCR kit and three RFLP single locus probes. A comparison between each child and all unrelated men resulted in 11,023 man / child pairs. Less than three excluding STRs were found in 125 child / unrelated man pairs (1.13%). Additional analysis of RFLP results reduced the number of ambiguous cases to 35. Half-sibling pairs were simulated using STR results from 20 cases with high paternity probabilities (group 1) and relatively low paternity probabilities (group 2). Using a commercially available computer program we calculated probabilities for 778 half-sibling pairs. In 35 pairs (4.49%) half-sibling probabilities over 90.0% could be calculated. Additional investigation of RFLP single locus probes did not lead to a more reliable evaluation of these results. The combined investigation of autosomal STRs and RFLP single locus probes can satisfactorily solve deficient paternities but does not contribute to the solution of questioned half-sibships. 相似文献

Major depression ranges among the most frequently diagnosed psychiatric disorders. Accordingly, diagnoses of depression are often underlying insurance, compensation or disability claims. This report evaluates the validity of clinicians’ diagnoses of major depression in a sample of claimants. In 2015, n = 127 consecutive cases were examined for medicolegal assessment. For all of them, a diagnosis of major depression had been established by clinicians. All testees underwent a psychiatric interview, a physical examination, they answered questionnaires for depressive symptoms according to DSM-5, embitterment disorder, post concussion syndrome (PCS) and unspecific somatic complaints. Performance and symptom validity tests were administered. Only 31% fulfilled the diagnostic criteria for DSM-5 major depression according to self-report, while none did so according to psychiatric assessment. Negative response bias was found in 64% of cases, feigned neurologic symptoms in 22%. Symptom exaggeration was indiscriminate rather than depression-specific. By self-report, 64% of the participants qualified for embitterment disorder and 93% for PCS. In conclusion, clinicians’ diagnoses of depression seem often confounded by improper assessment of the diagnostic criteria, confusion of depression with bereavement or embitterment and also by response bias. 相似文献

This article analyses the impact of widowhood upon women in early modern urban society in Holland. Widows were able to maintain their households and to minimize the discontinuity with their lives when married. A remarkably egalitarian inheritance and marital property law, access to a broad range of occupations, a privileged status, an extended poor relief system, institutionalised mutual assistance and new forms of financial provisions for widows enabled widows to survive after the loss of an adult male breadwinner. However, legal rights, social provisions and economic opportunities available to women in the Dutch Golden Age and thereafter, could not prevent social polarization after women lost their spouse. 相似文献

Early modern social institutions were modelled analogous to the family, and work within these institutions strongly depended upon the co-operation of women and men. This type of organization seems to be contradictory to processes of professionalization and bureaucratization. This article investigates to what extent professionalization and bureaucratization took place in early modern orphanages and how this influenced the gender division of work. By analyzing various occupations, remuneration and access to work in three Dutch orphanages it becomes clear that the frequently mentioned characteristics that made ‘typical’ women's work combinable with women's reproductive tasks, were not all applicable and cannot wholly explain female access to these occupations. Work was characterized by an increasing differentiation, hierarchy and, to a certain extent, bureaucratization tendencies. At the same time, the gender division sharpened. However, the late eighteenth century ideology of women as nurturers and the strong analogy to the role women were supposed to play within the household prevented exclusion from this domain. 相似文献

A model of dynamic climate governance: dream big, win small 总被引:2,自引:0,他引:2
Johannes Urpelainen 《International Environmental Agreements: Politics, Law and Economics》2013,13(2):107-125
In this article, I develop and evaluate a model of dynamic climate governance. The model is based on the premise that global warming is such a complex problem that present political realities do not allow an immediate solution to it. I propose that current mitigation activities should focus on building technological and political transformation potential to enable more ambitious climate cooperation in the future. Successful international climate cooperation could comprise a series of politically feasible “small wins” guided by a “big dream” of a comprehensive future climate regime. The analysis contributes to the emerging literature on the dynamics of climate governance by showing how coherence between multiple independent climate policies can be achieved, both across policymakers and over time. To illustrate how the model can be used, I apply it to technology agreements and North–South climate finance. 相似文献

The funding of global public goods, such as climate mitigation, presents a complex strategic problem. Potential recipients demand side payments for implementing projects that furnish global public goods, and donors can cooperate to provide the funding. We offer a game‐theoretic analysis of this problem. In our model, a recipient demands project funding. Donors can form a multilateral program to jointly fund the project. If no program is formed, bilateral funding remains a possibility. We find that donors rely on multilateralism if their preferences are relatively symmetric and domestic political constraints on funding are lax. In this case, the recipient secures large rents from project implementation. Thus, even donors with strong interests in global public good provision have incentives to oppose institutional arrangements that promote multilateral funding. These incentives have played an important role in multilateral negotiations on climate finance, especially in Cancun (2010) and Durban (2011). 相似文献

This article asks if, when, and why different groups of voters behave differently in the wake of economic downturns. We examine two Swedish elections (1994 and 2010) that were held just after two deep recessions (the financial crisis of 1991–1993 and the 2008–2009 Great Recession). We find that group differences were much larger in 2010 than they were in 1994. After the 1991–1993 recession, the government's electoral support declined across the board. In 2010, there were large differences between voters with low economic status (who were unlikely to support the government) and voters with high economic status (who were likely to do so). Our findings suggest that group differences in electoral behavior after an economic downturn depend on contextual differences across elections. We argue that future research should pay close attention to the magnitude of economic shocks, the development of asset prices (especially real estate), and changes in social policy. 相似文献
