Forensic Case Reports Presenting Immersion Pulmonary Edema as a Differential Diagnosis in Fatal Diving Accidents

Immersion Pulmonary Edema (IPE) reduces the transport of gases over the respiratory membrane due to edema in the interstitium and respiratory zones. IPE has previously been described in both swimmers and divers, with a few known fatal cases. We have reviewed 42 SCUBA and snorkeling‐related drowning deaths, and through a thorough analysis of each case, including both diving physiology and forensic pathology, we present IPE as a differential diagnosis to drowning in four cases. Our findings propose that; absence of watery content in the stomach and conducting airways, and liquid filled lungs without hyperexpansion, may be compatible with IPE. We suggest that IPE should be considered in cases where witness testimony reveals; no obvious signs of aspiration and rapid respiratory deterioration despite continuous breathing through an appropriate air source. The diagnosis should be based on the overall impression, including both the autopsy findings and the circumstances regarding the accident.     

Political Investment Cycles in Democracies and Autocracies

Extant research has shown considerable interest in whether host countries’ political uncertainty impedes foreign direct investment (FDI). Building upon the scholarly consensus on the adverse impact of political uncertainty on FDI, this article demonstrates that the extent to which investment climates are unpredictable varies cyclically, on the basis of election timing in democracies and leadership turnover in autocracies. The empirical results show that in presidential democracies, FDI tends to slowly increase after an executive election and then decline as the next executive election nears. However, I find that an electoral investment cycle is not found in parliamentary democracies where election timing is irregular, less predictable, and endogenous to domestic economic conditions. I also find that a similar political investment cycle exists in autocracies not through electoral cycle but through leadership tenure cycle. The level of FDI inflows tends to be relatively low early in autocrats’ tenure when political uncertainty is high and rise as autocratic leadership tenure increases over time but eventually wane again as autocratic leadership is destabilized in the late period of power transition. The findings indicate the existence of heterogeneous political investment cycles, depending on regime type.     

Exclusive contracts with private information in successive differentiated oligopolies

The purpose of this article is to analyze the incentives of manufacturers to deal exclusively with retailers in bilaterally duopolistic industries with brand differentiation by manufacturers. In contrast with the previous literature, exclusive contracts are shown to generate higher profits for manufacturers and retailers selling highly differentiated products, who thus have an incentive to insist on exclusive contracting. However, if the products are close substitutes no exclusivity will emerge in equilibrium. Furthermore, we show that exclusive contracts decrease both consumer and social welfare.     

How Do Scientists Respond to Performance-Based Incentives? Evidence From South Korea

ABSTRACT

Although a growing number of universities worldwide have adopted performance-based incentive systems to improve their ranking and reputation, empirical evidence of the effectiveness of such incentives is limited. By analyzing data on over 1,000 scientists in a Korean university over a nine-year period, the present study suggests that performance-based incentive systems may work effectively in academia. As the university increased its financial rewards for publication quantity and quality, both the number of publications and the average impact factor of the target journal improved. However, raising the minimum publication requirements for promotion increased publication quantity but reduced publication quality. To avoid unintended responses, such as replacing publication quantity for quality, any performance-related pay structure must therefore be carefully designed to reflect multiple organizational goals.     

Alliance Proximity and Effectiveness of Extended Deterrence

This article examines whether geographical proximity between defensive allies and a protégé increases the likelihood of successful extended general deterrence. I argue that proximate allies are better at making a credible deterrent threat because proximate allies are more willing and able to help alliance partners in times of crisis than distant ones. This claim is theorized by examining how geographical distance influences the international and domestic costs of alliance commitments. The empirical tests reveal that a potential aggressor is less likely to initiate a militarized dispute against a target with proximate defensive allies. Furthermore, I find that the power of proximate defensive allies is a more significant determinant of successful extended general deterrence than that of distance allies. Interestingly, I also find that the constraining effects of geographical distance on the effectiveness of extended general deterrence have been alleviated by advancements in military technologies throughout history.     

Policy learning and policy change: learning from research citations

Although the seminal article by Bennett and Howlett (Policy Sciences 25: 275–294, 1992) on policy learning and change has been one of the top five most cited articles in Policy Sciences, no attempt has yet been made to provide a citation analysis showing how its impact has evolved over time. This paper reports the findings of a study that provides a systematic analysis of the citing articles published in academic journals during the period 1992–2017.
