Abstract In recent years a lively debate has emerged concerning the empirical status of the traditional proximity spatial model versus a directional model of voter choice. The central reason for this scholarly interest concerns these models' contrasting implications for parties' policy positioning, with the directional model motivating parties to present extreme policies, but the proximity model promoting centrist positions. To this point, however, there exist no studies that compute parties' optimal strategies in historical elections, for these competing models. This article addresses this issue, by examining party policy strategies in a multiparty electorate for three different vote models: (a) the proximity model, (b) a directional model (c) a mixed model which combines proximity and directional components. Each model incorporates past voting history and the random effects of unmeasured variables. Using parameter estimates derived from analyses of survey data from the 1989 Norwegian Election Study we compute — for each of these vote models — the configuration of party policy positions that maximize each party's vote share in relation to those of the other parties. We find that for each model, such a vote–maximizing configuration exists, but — for the proximity model — represents an unrealistic, tightly clustered array. A mixed proximity–directional model, however, provides by far the most convincing account of parties' actual policy strategies with regard to dispersion and vote share. 相似文献

This study uses data collected in rural Egypt to estimate a micro‐level model of the economic and demographic determinants of international migration. This model uses predicted income functions to establish origin incomes (incomes excluding remittances). Three findings are noteworthy. First, the results suggest that education may not necessarily be positively correlated with migration. Second, the data indicate that the relationship between income and migration is that of a flat, inverted U‐shaped curve. Third, when the combined effects of income and land are considered, males from poor and landless households have the highest propensity to migrate. Poverty and landlessness combine to push rural Egyptians to work abroad. 相似文献

Shuttle and Online Mediation: A Review of Available Research and Implications for Separating Couples Reporting Intimate Partner Violence or Abuse 下载免费PDF全文

Whether family law cases with a history of severe intimate partner violence and/or abuse (IPV/A cases) should have the option of settling family‐related issues using mediation is the subject of significant debate. Recommendations for potentially safer ways to mediate IPV/A cases have been developed, including shuttle and online mediation. Given the current lack of research on these forms of mediation with IPV/A cases, we review the research on shuttle and online mediation in other contexts and theorize how the findings might apply to IPV/A cases. We argue that, although online and shuttle mediation may benefit IPV/A cases, aspects of these procedures require special considerations. 相似文献

The Company You Keep: How Voters Infer Party Positions on European Integration from Governing Coalition Arrangements 下载免费PDF全文
James Adams Lawrence Ezrow Christopher Wlezien 《American journal of political science》2016,60(4):811-823
Recent studies document that voters infer parties’ left‐right positions from governing coalition arrangements. We show that citizens extend this coalition‐based heuristic to the European integration dimension and, furthermore, that citizens’ coalition‐based inferences on this issue conflict with alternative measures of party positions derived from election manifestos and expert placements. We also show that citizens’ perceptions of party positions on Europe matter, in that they drive substantial partisan sorting in the electorate. Our findings have implications for parties’ election strategies and for mass‐elite policy linkages. 相似文献

When virgin female flies were injected with 1μ of water in the thorax or had the thorax punctured, the number which subsequently
mated was significantly reduced. The effect was not immediately apparent, but increased up to 4 to 6 days after treatment
and persisted until at least 14 days post-treatment. Injection of water into the abdomen through the base of the ovipositor
did not reduce subsequent mating.
Zusammenfassung Wenn jungfr?ulichen Fliegen 1 μl Wasser in den Thorax injiziert oder ihr Thorax punktiert wurde, so wurde die Zahl derer, die sich sp?ter paarten, signifikant reduziert. Dieser Effekt wurde nicht unmittelbar offenbar, sondern wuchs an bis zu 4–6 Tage nach Behandlung und blieb mindestens bis 14 d nach Behandlung erhalten. Injektion mit Wasser ins Abdomen durch die Basis des Ovipositors reduzierte nachfolgende Paarungen nicht.相似文献

Postmortem monocular indirect ophthalmoscopy permits examination of the posterior fundus and peripheral retina even if there is less than perfect anterior segment media such as postmortem corneal clouding. Light directed through the decedent's pupil from a bright focal light source illuminates the fundus and reflected light from the retina is then projected out of the eye. An aspheric condensing lens positioned in front of the eye focuses the retinal image at the focal plane of the lens. The real inverted, laterally reversed image comprises a wide field of view permitting evaluation of the decedent's fundus for retinal hemorrhages and other lesions. 相似文献
