Questions persist regarding the robustness of cross-sectional estimates of effects of variables that are themselves endogenous
to the participation process. On one hand, the consequences of working on a campaign have interesting implications for democratic
society. Less benign, however, is the possibility that failure to control for reciprocal processes leads to biased estimates
of the causes of campaign participation. I use a panel of Democratic and Republican contributors interviewed following each
of the past three presidential elections (1996, 2000, and 2004) to explore the relationships between campaign participation
and three variables typically parameterized as predictors of participation: receiving a contact, ideological extremism, and
strength of party identification. The effect of strength of party identification on campaign participation proves robust;
however, I find that nearly all of the associations between contacts and participation and ideological extremism and participation
appear to extend from, not into, participation and past participation.

Does Workplace Experience Enhance Political Participation? A Critical Test of a Venerable Hypothesis
Per Adman 《Political Behavior》2008,30(1):115-138
Several schools of thought claim that citizens can develop their democratic skills at the workplace. Here I focus on the hypothesis
put forward by Carole Pateman and by Sidney Verba and colleagues that state that by practicing civic skills and democratic
decision-making at the workplace, citizens become more active in politics. I test the hypothesis with a nationally representative
panel survey of the Swedish population. My findings contradict previous empirical research as no impact on political participation
was discovered. I argue that the effects may have been overestimated in prior studies because the tests were based on cross-sectional
data: insufficient care was taken with a number of significant methodological problems. The study points to the importance
of using panel models when investigating the causes of political participation.

AbstractWhile many studies have identified an association between social class and economic preferences, we know little about the implications of changes in class location for these preferences. This article assesses how social class and intra-generational class mobility affect economic preferences drawing on longitudinal data from the British Household Panel Survey. In doing so, the article adopts a post-industrial perspective that considers horizontal and vertical class divisions. Even when time-invariant characteristics of individuals are kept constant (through fixed-effects estimation), it is found that both vertical and horizontal class location explain economic preferences. Thus, these estimations suggest that social class moulds preferences, even when accounting for factors that can lead to selection into classes. Moreover, people who change classes hold different economic preferences than their peers in the class of origin, but do not completely assimilate into their class of destination. This implies that growing intra-generational class mobility could undermine the class basis of political conflict. 相似文献

EU issue voting in European Parliament elections has been shown to be highly conditional upon levels of EU politicization. The present study analyzes this conditionality over time, hypothesizing that the effect of EU attitudes on EP vote preferences is catalyzed as EP elections draw closer. In contrast to extant cross-sectional post-election studies, we use a four-wave panel study covering the six months leading up to the Dutch EP elections of 2014, differentiating between party groups (pro, anti, mixed) and five EU attitude dimensions. We find that EU issue voting occurs for both anti- and pro-EU parties, but only increases for the latter. For mixed parties we find no effect of EU attitudes, yet their support base shifts in the anti-EU direction as the elections draw closer. The overarching image, however, is one of surprising stability: EU attitudes form a consistent part of EP voting motivations even outside EP election times. 相似文献

ABSTRACT Do framing strategies that are effective at encouraging pro-social behavior, such as participation in human rights campaigns, also mobilize support for violence within the same subjects? We use an experimental research design to examine individuals’ reactions to personal, humanizing narratives about past victimization. Participants are randomly assigned to one of eight treatment groups, which variously highlighted the humanity of the subject, the intensity of the past violence, and/or an evocative photograph of the subject that underscores her loss and vulnerability. We expect narratives that emphasize the subject’s humanity will encourage the audience to see the subject as innocent and as a victim, but also to feel angry about her experience. As a result, individuals will be more likely to defend the subject’s human rights, and to condone her use of retributive violence. We find that humanizing narratives lead respondents to simultaneously support a human rights appeal on the subject’s behalf and her use of retributive violence. Perceiving the subject in the narrative as innocent or as a victim mediates these effects, but anger often does not. 相似文献

We conducted and analyzed several internet surveys in order to understand the profile of global research integrity and ethical awareness, encompassing global population distribution. These were (1) the global distribution of Committee of Publishing Ethics (COPE) membership; (2) the global distribution of “Integrity” or “Ethics” journals; (3) the level of academic integrity awareness in European higher education institutions and (4) awareness of academic integrity in the top universities of Asia and Africa. The results of this survey series highlight seriously imbalanced awareness of research integrity and publishing ethics across the world, especially in developing areas with the highest population density. We therefore propose a new index, the “Academic Integrity Awareness Index” for future discussions across the linked spheres of publishing and research. 相似文献

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.
Key points
- Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
- Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
- These metrological principles also apply to individuation of unique objects in general.

It may be difficult to distinguish the cause of death in drowning cases without specific findings. The aim of this study was to explore the forensic value of thoracic postmortem computed tomography (PMCT) using routine images and three-dimensional (3D) image reconstructions. The imaging data of PMCT examinations of six drowning cadavers, aged 21–54 years, were analyzed. Twelve victims of sudden death from coronary artery disease (CAD) were chosen as a control group. After 3D bilateral lung images were reconstructed using image processing software, an interactive medical image control system was used to measure and analyze parameters including lung volume, lung volume ratio, mean CT value of the whole lung, and lung CT value distribution curves. Lung volume and lung volume ratio were used to assess the shape changes of the lung. Lung CT value distribution curves showed the corresponding number of pixels of the different CT values in the lung image. Lung volume was not significantly larger in drowning cases (mean 2 958 cm3) than in controls (mean 2 342 cm3). Lung volume ratio values in the drowning group (mean 0.3156) were greater than those in the control group (mean 0.2763); (P = 0.02). There was no significant difference between the drowning and control group in the mean CT value of the whole lung. There were differences between lung CT value distribution curves in drowning victims and controls, with drowning victims showing a single peak and CAD cases showing a bimodal distribution. Thoracic PMCT is helpful for the forensic medical diagnosis of drowning. Lung volume ratio and lung CT value distribution are potential indicators to distinguish between drowning and CAD. 相似文献
