Summary

The nobility and the Netherlands Senate 1815–1830

From 1815 to 1830 the northern and southern Netherlands formed a single kingdom under Guillaume I. In this kingdom the nobility was the only social order to enjoy special political rights. The political influence the nobility could exercise as an order was primarily at the provincial level. The Corps Equestres had a role as a sort of electoral college for the Provincial Estates of the separate provinces. In 1815, after the States General had been divided into two chambers, the influence of the provinces made itself felt particularly through the elections for the Second Chamber, the members of the First Chamber, the Senate, being appointed by the king. Despite the fact that over ninety percent of them belonged to the nobility, the nobility as an order never became a political group exercising power at the national level.  相似文献

Agricultural intensification, or increasing yield, has been a persistent theme in policy interventions in African smallholder agriculture. This article focuses on two hegemonic policy models of such intensification: (1) the ‘Alvord model’ of plough-based, integrated crop-livestock farming promoted in colonial Zimbabwe; and (2) minimum-tillage mulch-based, Conservation Agriculture, as currently preached by a wide range of international agricultural research and development agencies. An analysis of smallholder farming practices in Zimbabwe's Zambezi Valley, reveals the limited inherent understanding of farmer practices in these models. It shows why many smallholder farmers in southern Africa are predisposed towards extensification rather than intensification, and suggests that widespread Conservation Agriculture adoption is unlikely.  相似文献

In recent years, voluntary associations and political organizations have increasingly relied on Internet-based mobilization campaigns, replacing traditional forms of face-to-face recruitment and mobilization. Within the literature, one can observe an intensive debate about the possible consequences of this transition. Most importantly, the question is whether political mobilization through the Internet is just as effective as mobilization in a face-to-face setting. In this article, we report on a mobilization experiment using both traditional (face-to-face) and modern (Web site) incentives for mobilization. The experiment was conducted among undergraduate students in Belgium and Canada and included a test of medium-term mobilization effects. Results suggest that the Internet is successful in transferring knowledge and raising issue salience among respondents, but neither experimental manipulation led to significant behavioral changes. We do not find any indication that among this experimental sample Internet-based mobilization would be less effective than traditional face-to-face forms of mobilization.  相似文献

We wish to describe further developments to a method previously reported on the detection of 2-phenoxyethanol in ink. The solid-phase microextraction (SPME) sampling technique, together with gas chromatography-mass spectrometry (GC-MS), has been used to quantify solvents in writing ink. In conventional approaches, the analysis of ink on documents requires some degree of destructive sampling. The methods commonly used remove ink samples from paper using a scalpel or a paper punch. To avoid document destruction, a sampling cell was constructed that allows solvents to be adsorbed directly onto the SPME fiber from the headspace above the document surface. Analytes (ink volatiles) are then desorbed from the SPME fiber on a gas chromatograph equipped with a mass selective detector (GC-MSD). With this method, it was possible to detect the presence of ink solvents on documents for a period lasting up to c. 2 years.  相似文献

Kassin et al. (Police-Induced Confessions: Risk Factors and Recommendation, 2009) provide a detailed and thoughtful analysis of how police interrogation practices might elicit false confessions from innocent suspects. The purpose of this commentary is to provide a brief review of a relatively recent development in Canadian police investigation practice and discuss how this procedure may increase the likelihood of police-induced false confessions. The so-called “Mr. Big Technique” is a non-custodial interrogation tactic wherein suspects are drawn into a supposed criminal organization (actually an elaborate police sting) and subsequently told that to move up in the organization, they must confess to a crime. In this article, we describe this remarkable interrogation technique and discuss issues relevant to the potential induction of false confessions.  相似文献

In France, Germany, Spain, and the United Kingdom, the decades from the late 1980s to the present have witnessed significant change in health policy. Although this has included the spread of internal competition and growing autonomy for certain nonstate and parastate actors, it does not follow that the mechanism at work is a "neoliberal convergence." Rather, the translation into diverse national settings of quasi-market mechanisms is accompanied by a reassertion of regulatory authority and strengthening of statist, as opposed to corporatist, management of national insurance systems. Thus the use of quasi-market tools brings state-strengthening reform. The proximate and necessary cause of this dual transformation is found in the work of small, closely integrated groups of policy professionals, whom we label "programmatic actors." While their identity differs across cases, these actors are strikingly similar in functional role and motivation. Motivated by a desire to wield authority through the promotion of programmatic ideas, rather than by material or careerist interests, these elite groups act both as importers and translators of ideas and as architects of policy. The resulting elite-driven model of policy change integrates ideational and institutionalist elements to explain programmatically coherent change despite institutional resistance and partisan instability.  相似文献

Pressure is mounting for states to become better at integrating its environmental policies into sector policy, a challenge often referred to as environmental policy integration (EPI). Policy research on EPI has grown to become a distinct and substantial field of study at the national and EU levels, where political commitment and interest in the topic have been large. In the study of international regimes, EPI analytical concepts have so far not been applied although the EPI quest is at least as important and critical at this level. This special issue addresses this gap, by combining these two sets of literature and examining various aspects of EPI in international regimes, its manifestations and its challenges. This introductory paper introduces key conceptual discussions underlying the development of this special issue, distils and discusses some of the key findings and messages from the four ensuing research articles and presents directions for future research. It finds that many EPI challenges and institutional barriers are strongly accentuated at international levels of governance, but also that similarities with the national level suggest that closer interactions between the two fields of study are warranted. At both levels, the EPI “game” is full of inherent tensions and goal conflicts, institutional constraints abound, and cognitive interactions and learning processes appear as key mechanisms to advance EPI. Suggestions for how to enhance EPI in international regimes are still tentative, and analysis beyond international relations and regime theory is needed to capture potential institutional innovations for advancing EPI.  相似文献

In case of suicide, the presence of multiple entrance wounds is always suspicious. We report the case of a man who committed suicide by shooting himself three times in the chest and the skull with a submachine gun. The weapon seems to have been initially pointed in the precordium area with a lethal lesion of the proximal aorta. Two other projectiles were fired by the weapon and hit the neck and the skull of the deceased. The presence of three entrance wounds despite a first fatal wound could finally be explained by the characteristics of the weapon and wounds. Most suicides related to multiple gunshot wounds are explained by a first nonlethal shot but the use of an automatic weapon can also be found. In these last cases, medicolegal and criminalistics aspects become important in differentiating suicide and homicide.  相似文献

The ability to identify whether a female has been pregnant or has given birth has significant implications for forensic investigations and bioarcheological research. The meaning of “scars of parturition,” their causes, and their significance are a matter of contention, with a substantial literature of re‐evaluations and tests of the relationship between pelvic scarring and parity. The aim of this study was to use meta‐analytic techniques (the methodological approach) to test whether pelvic scarring, namely dorsal pubic pitting and the preauricular groove, is a predictor of parity and sex. Meta‐analyses indicated that neither dorsal pubic pitting nor the preauricular groove are predictors of parity status, while dorsal pubic pitting is a moderate predictor of sex. A weak relationship between dorsal pubic pitting and parity was identified, but this is believed to be a product of the moderate relationship with sex. This calls into question whether any causal relationship between parity and pelvic scarring exists.  相似文献
