EFFECTS OF FATHER AND MOTHER PARENTING ON CHILDREN'S MENTAL HEALTH IN HIGH‐ AND LOW‐CONFLICT DIVORCES

This article studied the relations of children's mental health problems to the warmth of their relationship with their noncustodial father and custodial mother and the level of conflict between the parents. Using a sample of 182 divorcing families, multiple regression was used to test the independent effect of father warmth, mother warmth, and interparental conflict. Results indicated that father warmth and mother warmth were both independently related to lower child‐externalizing problems. However, the relations between mother and child warmth and child‐internalizing problems were different as a function of interparental conflict and level of warmth with the other parent. Implications for court practices and policies are discussed.     

Patterns of Transnational Terrorism, 1970–1999: Alternative Time-Series Estimates

Using alternative time-series methods, this paper investigates the patterns of transnational terrorist incidents that involve one or more deaths. Initially, an updated analysis of these fatal events for 1970–1999 is presented using a standard linear model with prespecified interventions that represent significant policy and political impacts. Next, a (regime-switching) threshold autoregressive (TAR) model is applied to this fatality time series. TAR estimates indicate that increases above the mean are not sustainable during high-activity eras, but are sustainable during low-activity eras. The TAR model provides a better fit than previously tried methods for the fatality time series. By applying a Fourier approximation to the nonlinear estimates, we get improved results. The findings in this study and those in our earlier studies are then applied to suggest some policy implications in light of the tragic attacks on the World Trade Center and the Pentagon on September 11, 2001.     

An empirical analysis of alternative ways that terrorist groups end

This paper implements discrete-time survival models to ascertain the determinants behind specific endings for terrorist groups during 1970–2007. Based on multinomial logit regressions, we estimate the hazard probabilities associated with three endings for terrorist groups: splintering from internal factors, being defeated by force, and joining the political process or achieving victory. We find that different covariates differentially impact each of these endings. In a second exercise, we split our sample of 586 terrorist groups into those that started before and after the beginning of 1990. In so doing, we find that survival factors differ between the two cohorts of groups. For both exercises, the determinants of survival comprise terrorist groups’ goals, their tactics and size, and base-country characteristics. Robustness tests conclude the paper.     

Terrorist group survival: ideology, tactics, and base of operations

The paper applies survival analysis to identify the determinants of terrorist group duration. Our sample includes 367 terrorist organizations that operated during 1970?C2007. Consistent with the theory, determinants of these groups?? survival include their tactics, sizes, ideological basis, regions of operation, and base-country characteristics. Cross-sectional and panel estimates are reported. Terrorist organizations fare better if they are larger in size, diversify their attack modes, are animated by religiosity rather than secular political goals, and base their operations in the Middle East or Africa. Groups?? longevity is bolstered by democratic institutions and an intermediate level of ethnic fractionalization at home.     

Who adopts MIND/FIND in INTERPOL��s fight against international crime and terrorism?

This article determines the key factors inducing INTERPOL countries to institute MIND/FIND, a technology which facilitates systematic searches of people, motor vehicles, and documents at international transit points. This integrated solution assists countries in curbing international crime and terrorism. Based on discrete-choice models, the analysis identifies income per capita, population, democratic freedoms, and anticipated searches for suspects as the key determinants of whether INTERPOL countries install MIND/FIND. Ethnic diversity, international arrivals, cost proxies, and arrests prior to adoption are not important considerations in decisions to install MIND/FIND. External financial support is an essential factor identifying likely non-adopters who installed MIND/FIND.     

Rent-seeking with non-identical sharing rules

The primary object of this paper is to examine the role of differential sharing rules within a collective rent-seeking setting on the possible non-existence of Nash equilibrium. Focusing on groups that distribute part of the rent equally among their members and the residual according to relative effort, we show that in rent-seeking societies applying the two polar sharing rules equilibrium never exists. In the general case where groups apply different but not necessarily the polar sharing rules, we study the relationship between group variability in distributing rents and the problem of non-existence of equilibrium in the rent-seeking game.     

Rent-seeking for pure public goods

In this paper we present a formal analysis of rent-seeking for public goods by two or more groups with different numbers of individuals. We begin by considering equally wealthy groups under risk neutrality, a case which constitutes our basic model. Several surprising and interesting results emerge from the analysis of this basic case. The problem is then extended to deal with (a) groups with different wealth levels, and (b) risk aversion. This last extension brings about a further crop of interesting and useful results.     

Fighting World War III: A suggested strategy

Abstract

Utilizing a rational‐actor policymaker model, this paper presents the necessary and sufficient conditions that must be satisfied for the formation of a transnational antiterrorist institution. Such an institution would tie together nations in their struggle against international terrorism. In particular, these institutions could provide crisis management, preemptive strikes, and retaliatory strikes. After analyzing the obstacles to the formation of such institutions, we present a specific proposal for a transnational commando unit. We chose the parameters of the proposed institution so as to maximize the likelihood of initial formation. In addition, we discuss how the transnational commando unit could, if properly designed, surmount the obstacles to formation. As terrorist groups increase their cooperation and stage incidents of a transnational kind, nations will have to turn to such institutions to increase the effectiveness of commando units, eliminate safe havens, and share intelligence. Although our proposal is more modest than those often put forth, once formed, our institution could evolve over time.
