Expanding Microfinance in Brazil: Credit Utilisation and Performance of Small Firms

We take advantage of the natural experiment generated by the exogenous change in government policy towards microcredit to evaluate the impact of the increased supply of microcredit on the utilisation of credit by micro-entrepreneurs. Based on micro-entrepreneurs' survey and administrative data from a microcredit programme in Brazil, we show that: the increased supply of microcredit raised formal credit utilisation and this does not crowd out the use of informal credit sources; formal credit taking improves business performance; and returns are larger for women- than for men-owned firms, but males employ significantly more workers after taking formal credit than females.     

Conditional Cash Transfers,Adult Work Incentives,and Poverty

Conditional cash transfer (CCT) programmes aim to alleviate poverty through monetary and in-kind benefits, as well as reduce future incidence of poverty by encouraging investments in education, health and nutrition. The success of CCT programmes at reducing poverty depends on whether, and the extent to which, cash transfers affect adult work incentives. In this paper we examine whether the PROGRESA programme of Mexico affects adult participation in the labour market and overall adult leisure time, and we link these effects to the impact of the programme on poverty. Utilising the experimental design of PROGRESA's evaluation sample, we find that the programme does not have any significant effect on adult labour force participation and leisure time. Our findings on adult work incentives are reinforced further by the result that PROGRESA leads to a substantial reduction in poverty. The poverty reduction effects are stronger for the poverty gap and severity of poverty measures.     

Undermining cooperation: donor-patrons and the failure of political conditionality

This study extends the debate concerning the feasibility of using foreign assistance to leverage political reforms in developing countries. This research combines both quantitative and qualitative methodologies in an effort to expand on the work done by previous scholars. Conclusions of the empirical analysis point to the finding that political conditionality is most effective when close cooperation exists between donors. This coordination, however, is frequently sabotaged by self-interested donor-patrons, illustrated by the case of Cameroon and France. This pattern is generalizable and significantly undermines the overall success rate of a political conditionality approach.     

Political Aspects of Taiwan's Security in a New Asian Environment

With the announcement in 2010 that sovereignty over the South China Sea was a national interest comparable to Taiwan or Tibet, China has created a new geopolitical situation in East Asia. Although Peking would seem to expect that her neighbors, all relatively smaller than China, will accept these new claims, both initial reactions and political science theory suggest instead that a countervailing coalition will be formed to offset them. Just what Taiwan will do, however, is an important question given the island's key strategic position, its democratic government, and its increasing connectedness with China. This essay reviews the history of American approaches to East Asian alliances, arguing that at one time Washington considered dropping ties with Tokyo in favor of Peking. Then it examines the new situation, finding the United States uneasily seeking to balance China and Taiwan likely to join in.     

The effects of specialized probation and recovery management checkups (RMCs) on treatment participation,substance use,HIV risk behaviors,and recidivism among female offenders: main findings of a 3-year experiment using subject by intervention interaction analysis

Objectives

To examine the effects of specialized probation and recovery management checkups (RMCs) on participation in substance use treatment, substance use, HIV risk behaviors, and recidivism.

Methods

Women (n?=?480) released from the Cook County Jail’s Department of Women’s Justice Services were randomly assigned to either an RMC or control condition and interviewed quarterly for 3 years (greater than 90% completion per wave). At the beginning of each quarter, women were classified as currently on probation (n?=?1984) or not (n?=?2516). Current probation (subject) and experimental condition (intervention nested within probation status) at the beginning of the quarter were used to predict outcomes in the next quarter. Data included self-reports, urinalysis findings, and county and state arrest records.

Results

In the quarter after being on probation (or not), women offenders reported higher rates of participation in substance use treatment and recovery support services, as well as lower rates of substance use and HIV risk behaviors. Nevertheless, they were more likely to commit crimes and be rearrested or reincarcerated. During quarters when the women were not on probation, RMCs were associated with significant increases in participation in substance use treatment and significant reductions in substance use and HIV risk behaviors. However, RMCs had no additional quarterly benefits when women were on probation. Higher levels of substance use treatment, self-help engagement, and reduced substance use predicted reduced recidivism.

Conclusions

This study demonstrates the effects of specialized probation and RMCs (when not on probation) on favorable outcomes for criminally involved women with substance use disorders.

     

Four new illicit cocaine impurities from the oxidation of crude cocaine base: formation and characterization of the diastereomeric 2,3-dihydroxy-3-phenylpropionylecgonine methyl esters from cis- and trans-cinnamoylcocaine

Four new impurities have recently been detected in the gas chromatographic signature profiles of many illicit cocaine hydrochloride exhibits. These impurities are only seen in exhibits that have been oxidized and are most prominent in samples that have been highly oxidized. Exhibits containing these compounds were subjected to gas and liquid chromatographic-mass spectrometric analyses to determine the identity of the impurities. These impurities were subsequently synthesized to verify their structures. Four diastereomeric diols formed from the oxidation of cis- and trans-cinnamoylcocaine were characterized by nuclear magnetic resonance spectrometry, mass spectrometry, and synthesis. Oxidation of cis-cinnamoylcocaine in neutral conditions yielded (2R,3R)-dihydroxy-3-phenylpropionylecgonine methyl ester and (2S,3S)-dihydroxy-3-phenylpropionylecgonine methyl ester, while trans-cinnamoylcocaine produced (2R,3S)-dihydroxy-3-phenylpropionylecgonine methyl ester and (2S,3R)-dihydroxy-3-phenylpropionylecgonine methyl ester. The recent appearance of these new impurities suggests that some illicit cocaine processors have modified their oxidation procedures of crude cocaine base for transformation into illicit refined cocaine hydrochloride.
