An exploration of multi‐country political conflict/cooperation interdependence

Previous investigations of dynamic conflict actions and reactions among major countries have generally assumed the unit of analysis to be either a dyad or a triad. Our objective of the papa‐is to explore this assumption. The empirical analysis employs quarterly political conflict/cooperation among the United States, the (former) Soviet Union, China, Japan, and (West) Germany from 1950 to 1991. The model consists of a system of dynamic multiple regression equations. Various groups formed among mese countries are tested to find out whether they can be considered an autonomous unit of analysis. The analysis reveals several groups of countries whose political relations can be considered to be autonomous. In particular, either the United States‐the Soviet Union dyad or the United States‐the Soviet Union‐China triad is not an appropriate, autonomous unit of analysis in dynamic conflict action‐reaction models, because these countries are significantly influenced by the presence of other countries. New directions for future research are also suggested.

RETHINKING THE “NORM” OF OFFENDER GENERALITY: INVESTIGATING SPECIALIZATION IN THE SHORT‐TERM

The life‐course approach to criminal career research has devoted a good deal of attention to the generality or specialization of offending behavior. Typically, extant research demonstrates versatility on the part of offenders, yet such findings could be attributable, at least in part, to time and measurement aggregation bias. This work uses a temporally disaggregated and individualized measure of diversity in offending to determine whether the previous findings of generality hold up to shifts in methodology. Using data from a sample of serious felons, results indicated that the magnitude of specialization is greater than in prior studies. Regression results indicated that certain demographic and local life‐circumstance variables are related to the extent of diversity. Theoretical and methodological implications are identified and discussed.     

An Empirical Research on the Impact of Credit Rationing on the R&D Investment——From a Perspective of Regional Differences

This paper uses a simplified theoretical model to analyze how the credit rationing affects the firms' R&D investment, and empirically tests the spatial heterogeneity in which the credit rationing affects R&D investment based on the large sample data of industrial firms in China. The empirical research shows that, the firms that suffer the more serious the degree of credit rationing, spend less R&D investment in terms of the overall situation. Other conditions remaining unchanged, the effect of credit rationing to R&D investment has obvious spatial heterogeneity in the area, and the inhibitory effect of credit rationing is not established in all regions, which depends on the regional financial development and the regional institutional quality. All kinds of robustness tests show that this hypothesis has better robustness.     

Novel O‐propyl,S‐propyl,and N‐propyl substituted 1,4‐naphthoquinones and 1,4‐anthraquinones as potential fingermark development reagents for porous surfaces

Lawsone is a 2‐substituted‐1,4‐naphthoquinone derivative, which has been proposed as an alternative to the reagents currently used for fingermark detection on porous surfaces. 2‐substituted‐anthraquinones, which contain an additional conjugated benzene ring, have a similar chemical structure to that of lawsone. In this study, a new series of 2‐substituted‐1,4‐naphthoquinones and 2‐substituted‐1,4‐anthraquinones were synthesized and completely characterized by¹H NMR,¹³C NMR, IR, and HPLC‐TOF/MS analyses. All newly synthesized 2‐substituted‐1,4‐quinones were investigated for their ability to develop latent fingermarks on porous surfaces, and this ability was compared with that of lawsone. Each fingermark developed was graded using an established method; thus, quantitative data were attributed to each fingermark. It has been demonstrated that the 1,4 ‐ quinones react with amino acids present in latent fingermarks on selected paper surfaces to produce faint yellow‐orange impressions, which exhibit strong photoluminescence when illuminated with a forensic light source at 440 nm and observed through a red filter. None of the compounds caused background darkening. The results obtained were generally similar to those of lawsone, however, 8‐dibromo‐2‐(propylamino)naphthalene‐1,4‐dione and 5,8‐dibromo‐2‐(propylthio)naphthalene‐1,4‐dione yielded better results for copier paper and colored (blue) copier paper used in this analysis. To the best of our knowledge, this is the first study to examine the role of 1,4‐anthraquinone derivatives as potential fingermark development reagents. The results indicate that 1,4‐quinones have a potential to be used as reagents for enhancement of latent fingermarks.     

THROUGH A DIFFERENT LENS: USING FILM TO TEACH FAMILY LAW

This article discusses the aspects of narrative and character development that make films a useful tool to supplement classroom legal education. Moreover, utilizing film is particularly effective for learning and exploring the dynamics of human relationships at the center of family law cases. When designing a film and family law course instructors should seek to promote creative thinking, cultural competence, student exploration of bias and assumptions and best practices for attorneys based on the examples provided in the film. Films make the learning process more fun, but still provide substantial opportunities to broaden students' concept of the impact of law on family members.     

Private Security in Guatemala: Pathway to Its Proliferation

It has become common to explain the proliferation of private security services as causally determined by crime rates and institutional weakness. This article on the contrary argues that other explanatory factors need to be emphasised, especially for post‐war societies: institutional trajectories and political processes. The article first presents the present situation of commercial and non‐commercial private security services in Guatemala (private security companies as well as security neighbourhood committees). Against this background it reconstructs mechanisms and critical junctures through which the Guatemalan state had sourced out policing functions to the private sector during the war and traces the reinforcement of these mechanisms in post‐war society. It argues that the proliferation of private security services is an outcome of the reinforcing of an institutional pattern of public security displacement to the private sphere. The continuity of self‐defence and vigilante organisations thereby emerges as a stronger explanatory factor of the proliferation of private security services in post‐war societies than their self‐explained authorisation through high crime rates.
