This article develops a model which tests the hypothesis that sectoral FDI flows from the United States to Mexico over a four‐year period can be explained by the ownership advantages of US multinationals. Theoretical developments in the concept of ‘ownership advantage’ are used to guide the formulation of the research. The findings suggest that direct investment into US MNEs’ affiliates in Mexico is driven by benefits derived from embedded human knowledge, technology‐embodied advantages, and possibly from scale advantages. Local R&D is negatively associated with FDI.  相似文献

Turnout is theorized to reflect elections' policy stakes. All else equal, a highly constrained policymaking context is expected to lower the potential policy stakes of a given election. This study tests if such contexts, which are characterized by multiple veto players, reduce electoral participation. According to time-series cross-sectional autoregressive dynamic lag models of turnout in 311 elections in 21 advanced industrialized democracies, additional veto players decrease turnout in both the short and long run. Moreover, the results suggest veto players conceptually fine-tune and empirically contribute to existing models of cross-national turnout. Hence this study has crucial implications for the students of electoral participation and scholars interested in the democratic outcomes of institutional design.  相似文献

Issue ownership (IO) has been an important concept in the analysis of party behaviour, party strategy and party competition for several decades. More recently, it has also been of growing interest for research on voting behaviour. Traditionally, IO has been regarded as a stable phenomenon where parties have different issue profiles and are advantaged by different political issues or issue‐areas. Recently, however, many studies have reported change and fluctuations of IO, and the same studies also makes it clear that we know surprisingly little about what might cause, or facilitate, change in issue ownership. In fact, we do not even have systematic studies of how stable issue ownership is, or how frequent shifts in issue ownership actually are. The aim of this article is to explore the extent of change and stability in issue ownership in Sweden. For this purpose, the Swedish national election studies from 1979 to 2010 are utilised. Although recent research has indicated that changes in IO have increased over time, this is not supported in the Swedish case. Instead, issue ownership seems never to have been a particularly stable phenomenon. However, in line with our theoretical expectations, we show that ownership of economic issues is more volatile compared to ownership of other issues.  相似文献

Lipset and Rokkan??s (Party system and voter alignments: cross national perspectives, Lipset and Rokkan eds., New York: Free Press, pp. 1?C64, 1967) sociological model of cleavages and the so-called ??freezing hypothesis?? dominate theorizing about party system formation. Torcal and Mainwaring (Br. J. Polit. Sci. 33:55?C84, 2003) show the relevance of a purely political cleavage for structuring the party system in the case of Chile, challenging the freezing hypothesis??s claims. They also dispute case-specific research that argues Chile??s party system still reflects a ??three-thirds?? division between Left, Right, and Center. Revisiting this debate, our study employs spatial maps of the party system. Such political-economy models are rare in studies of Latin American politics. The application here supports a democratic/authoritarian political cleavage in Chile.  相似文献

This article examines the ways in which divorce and child custody proceedings can impact employee productivity and suggests that it behooves businesses to become involved in supporting efforts to improve the process—both as a matter of community service and because it can impact their bottom line. This article further outlines some improvements that are being implemented or considered in various jurisdictions.
    Key Points for the Family Court Community
  • Divorce does not just impact the parties and their children. It also impacts the work productivity of the individuals involved.
  • The population of individuals seeking court involvement in child custody issues has changed, and new processes must be developed to address their needs.
  • There are new ideas about how to restructure the divorce process in ways that could benefit both the individuals and their employers.

This study was conducted to characterize the chemistry associated with the decomposition of human remains with the objective of identifying time-dependent biomarkers of decomposition. The purpose of this work was to develop an accurate and precise method for measuring the postmortem interval (PMI) of human remains. Eighteen subjects were placed within a decay research facility throughout a four-year time period and allowed to decompose naturally. Field autopsies were performed and tissue samples were regularly collected until the tissues decomposed to the point where they were no longer recognizable (encompassing a cumulative degree hour (CDH) range of approximately 1000 (approximately 3 weeks)). Analysis of the biomarkers (amino acids, neurotransmitters, and decompositional by-products) in various organs (liver, kidney, heart, brain, muscle) revealed distinct patterns useful for determining the PMI when based on CDHs. Proper use of the methods described herein allow for PMIs so accurate that the estimate is limited by the ability to obtain correct temperature data at a crime scene rather than sample variability.  相似文献

This article argues that prizes can help stimulate medical innovation, control costs and ensure greater access to new medicines and vaccines. The authors explore four increasingly ambitious prize options to reward medical innovation, each addressing flaws in the current patent system. The first option promotes innovation through a large prize fund linked to the impact on health outcomes; the second option rewards the sharing of knowledge, data, and technology with open source dividends; the third option awards prizes for interim benchmarks and discrete technical problems; and the final option removes the exclusive right to use patented inventions in upstream research in favor of prizes. The authors conclude that a system of prizes to reward drug development would break the link between R&D incentives and product prices, and that such a reform is needed to improve innovation and access to new medicines and vaccines.  相似文献

  • It is time for a national dialogue about the feasibility of creating out‐of‐court alternatives for separating and divorcing families.
  • Research indicates that separating parents who provide their children with consistency, emotional support, and low conflict help children successfully adapt in the transition process.

The purpose of this study was to identify and compare patterns of trauma associated with AutoPulse® CPR and manual CPR. Finalized autopsy records from 175 decedents brought to the Harris County Institute of Forensic Sciences were reviewed, 87 received manual‐only CPR, and 88 received AutoPulse® CPR (in combination with manual CPR as per standard protocol). The characteristic pattern observed in manual‐only CPR use included a high frequency of anterior rib fractures, sternal fractures, and midline chest abrasions along the sternum. The characteristic pattern observed in AutoPulse® CPR use included a high frequency of posterior rib fractures, skin abrasions located along the anterolateral chest and shoulder, vertebral fractures, and a few cases of visceral injuries including liver lacerations, splenic lacerations, and hemoperitoneum. Knowledge of the AutoPulse® CPR injury pattern can help forensic pathologists differentiate therapeutic from inflicted injuries and therefore avoid an erroneous assessment of cause and manner of death.  相似文献
