Bilateral Investment Treaties,Credible Commitment,and the Rule of (International) Law: Do BITs Promote Foreign Direct Investment?

A long line of research, beginning with Macaulay's (1963) well‐known study of “Non‐Contractual Relations in Business,” suggests that the formal trappings of domestic law often have effects on private behavior that are, at best, “indirect, subtle, and ambiguous” ( Macaulay 1984 :155). Law and society scholars have spent somewhat less time exploring whether international law's effects on behavior are similarly attenuated. In this article I examine whether foreign investors take the presence of strong formal international legal protections into account when deciding where to invest. I focus on whether the presence of bilateral investment treaties, or BITs, meaningfully influences investment decisions. I present results from a statistical analysis that examines whether the formally strongest BITs—those that guarantee investors access to international arbitration to enforce investors' international legal rights—are associated with greater investment flows. I find no clear link between treaty protections and investment, a finding consistent with past law and society research but in tension with claims common in the BIT literature that the treaties should have dramatic effects on investor behavior.     

A Critical Review of the Psychometric Evidence Base of the Child Abuse Potential Inventory

Screening for potential child abuse is an essential component of work in many child and family services. The Child Abuse Potential inventory (CAP; Milner 1986) is one measure developed to help in this task. The primary aim of this review is to critically evaluate studies reporting psychometric information of the CAP. A previous paper by Milner (Clinical Psychology Review 14(6): 547–583 1994) reviewed studies evaluating the psychometric properties of the measure up to 1994. Since then over 100 articles have been published that consider the measurement properties of this tool. This review considers 27 papers published since Milner’s (Clinical Psychology Review 14(6): 547–583 1994) review that clarify previous findings in relation to specific psychometric properties of the CAP. In particular, this review focuses on studies that provide information on the cross-cultural validity of the CAP, on the internal consistency of the CAP measure as a whole and its subscales, or on sensitivity and specificity classification rates. Studies providing information on the differential validity of the CAP (using at least two differentiated sample groups) or the efficacy of the CAP to identify change are also considered. Published evidence suggests that the CAP can help assess for a range of difficulties associated with increased risk for physical child abuse. The CAP scales have shown good internal consistency estimates across sample groups and cultures, with similar underlying themes for CAP factors reported for the different cultures studied. The differential validity of the CAP has also been shown, although sensitivity and specificity classification rates have varied. The CAP appears able to indicate some degree of pre—to post-intervention change, although further investigation is required to clarify what changes in CAP scores actually reflect. Further investigation of this measure in other countries is also required.     

Stable isotope models to predict geographic origin and cultivation conditions of marijuana

Here we describe stable isotope based models using hydrogen and carbon isotope ratios to predict geographic region-of-origin and growth environment for marijuana, with the intent of applying these models to analyses of marijuana trafficking in the USA. The models were developed on the basis of eradication specimens and border specimens seized throughout the USA. We tested reliability of the geographic region-of-origin and growth environment models with a “blind” set of 60 marijuana eradication specimens obtained from counties throughout the USA. The two geographic region-of-origin model predictions were 60–67% reliable and cultivation environment model predictions were 86% accurate for the blind specimens. We demonstrate here that stable isotope ratio analysis of marijuana seizures can significantly improve our understanding of marijuana distribution networks and it is for that purpose that these models were developed.     

To Patent or Not: Faculty Decisions and Institutional Success at Technology Transfer

We draw on qualitative data derived from field work on two university campuses to develop an explanation for widely disparate rates of new invention disclosure. We argue that faculty decisions to disclose are shaped by their perceptions of the benefits of patent protection. These incentives to disclose are magnified or minimized by the perceived costs of interacting with technology transfer offices and licensing professionals. Finally, faculty considerations of the costs and benefits of disclosure are colored by institutional environments that are supportive or oppositional to the simultaneous pursuit of academic and commercial endeavors.     

Bureaucratic discretion,social equity,and the administrative legitimacy dilemma: Complications of New Public Service

Bureaucratic discretion continues to be one of a public administrator's primary powers while at the same time being one of their most controversial. Used in a positive way, bureaucratic discretion can enhance social equity; however, this practice can create administrative legitimacy dilemmas. As such, this paper conceptually discusses the theoretical position of public administrators that contributes to their engagement in legitimacy dilemmas, which is further complicated by the tenets of New Public Service. We argue that if public administrators are engaged in authentic interactions with the public and use their discretion to reflect the interests of the public, then they are engaged in truly democratic governance. We place this argument in the context of achieving social equity and highlight an avoided question in public administration. Finally, recommendations for future research are offered as a means progressing the social equity agenda in public administration.     

Dimensions of competition in urban cannabis markets

We report the results of a survey of legal cannabis retail operators in the two largest urban centres of a Canadian province that uses a fully private model to determine the dimensions of competition between retail outlets. We find that, in addition to expected price and location competition, customer loyalty is central in the opinion of retailers. Firms also did not see the illicit market as their primary competition, instead identifying nearby legal retailers as their main competitors. Restrictions on advertising loomed large in the minds of retailers as a policy-based impediment to their success. These results are further supported by visual inspection of the exterior of all stores in one of the urban centres.
