Management response to the demands of global fresh fruit markets: Rewarding harvesters with financial incentives

Competition in global fresh fruit markets is now much more intense than a decade ago. Producers and exporters face an increasing number of quality requirements and regulations that are costly and challenge established practices: paying harvesters by the amount they harvest and trying to control quality with sanctions. Based on a field study, this article discusses how lemon producers in northern Argentina are responding to these challenges; why some have responded only by introducing non-contractual innovations, while others by rewarding harvesters for careful performance to insure fruit quality. The findings elucidate arguments about the instrumentality of transaction costs on the choice of both managerial practices and forms of remunerating labourers. It also illustrates that added quality demands of foreign markets eased the task of harvesters, but had a varying effect on labourers' income.     

Designer Psychostimulants in Urine by Liquid Chromatography–Tandem Mass Spectrometry,

Designer psychostimulants are known by recreational drug users to produce a complex array of adrenergic and hallucinogenic effects. Many of these drugs are not targeted during routine toxicology testing and as a consequence, they are rarely reported. The purpose of this study was to develop a procedure for the detection of 15 psychostimulants in urine using liquid chromatography–tandem mass spectrometry (LC‐MS/MS), specifically 2,5‐dimethoxy‐4‐bromophenethylamine (2C‐B), 2,5‐dimethoxy‐4‐chlorophenethylamine (2C‐C), 2,5‐dimethoxy‐4‐methylphenethylamine (2C‐D), 2,5‐dimethoxy‐4‐ethylphenethylamine (2C‐E), 2,5‐dimethoxyphenethylamine (2C‐H), 2,5‐dimethoxy‐4‐iodophenethylamine (2C‐I), 2,5‐dimethoxy‐4‐ethylthiophenethylamine (2C‐T‐2), 2,5‐dimethoxy‐4‐isopropylthiophenethylamine (2C‐T‐4), 2,5‐dimethoxy‐4‐propylthiophenethylamine (2C‐T‐7), 2,5‐dimethoxy‐4‐bromoamphetamine (DOB), 2,5‐dimethoxy‐4‐chloroamphetamine (DOC), 2,5‐dimethoxy‐4‐ethylamphetamine (DOET), 2,5‐dimethoxy‐4‐iodoamphetamine (DOI), 2,5‐dimethoxy‐4‐methylamphetamine (DOM), and 4‐methylthioamphetamine (4‐MTA). Analytical recoveries using solid‐phase extraction were 64–92% and the limit of detection was 0.5 ng/mL for all drugs except 2C‐B (1 ng/mL). The assay was evaluated in terms of analytical recovery, precision, accuracy, linearity, matrix effect, and interferences. The technique allows for the simultaneous detection of 15 psychostimulants at sub‐ng/mL concentrations.     

Analysis of cognitive inhibition and flexibility in juvenile delinquents

Executive functions are still developing during adolescence. It is important to analyse if juvenile delinquency is related to a delay in the development of these functions. The objective of this study was to analyse cognitive inhibition and flexibility, two components of executive functions, in juvenile delinquents. Participants were 81 males, 17.46 ± 1.60 years old. Three groups were compared: a juvenile delinquent inmate group (IG), an age-paired group (APG), and an age- and education-paired group (AEPG). A modified Stroop task was used to assess cognitive inhibition and flexibility. The IG and the AEPG (low-education adolescents) had significantly more difficulties than the APG on inhibition; the IG and the AEPG had no significant differences. No group differences were found on flexibility. Since all low-education adolescents have difficulties on inhibition, these difficulties are not an exclusive characteristic of juvenile delinquents. Analysis of cognitive processes in juvenile delinquents must control for education to determine how specific are the difficulties found in these adolescents.     

Insurgent Strategies in the Post-Cold War: The Case of the Revolutionary Armed Forces of Colombia

This article analyzes the adaptation of the Revolutionary Armed Forces of Colombia (FARC) to the post-Cold War strategic scene. In this process of change the Colombian guerrilla organization has broken away from the traditional behavior patterns of Latin American armed groups in four key ways. First, the FARC has reduced the rigidity of its ideology in order to make its political message more attractive. Second, it has made a great effort to boost its military potential. Third, it has established independent channels of funding and arms supply. Finally, the Colombian rebels have developed a very decentralized organic structure that nevertheless maintains a sufficient degree of cohesion. These innovations have made the FARC a new model of insurgency that has managed to corner the Bogota government and destabilize a significant part of the Andean region.     

Do juvenile drug courts reduce recidivism?: Outcomes of drug court and an adolescent substance abuse program

Juvenile drug courts have emerged as “innovative” responses to juvenile drug offenders, but comparatively little is known about their operations. This paper presents results of a retrospective comparison of drug court participants to an adolescent substance abuse program (ASAP) to examine which participants fared better in terms of future recidivism. Using data collected from official case files, we compared recidivism levels for all juveniles (n = 150) terminated from drug court between 1996 and 1999 with those of a random sample of juveniles (n = 158) terminated from ASAP during 1994 and 1995. Biand multivariate analyses were conducted to identify whether significant differences existed between the groups concerning re-arrest (recidivism) over a 24-month post-release observation period. Study results highlighted by logistic regression analyses suggesting that juveniles in drug court were no more likely to recidivate than were juveniles in ASAP is a positive finding for the drug court program and is an indication that the program is working, especially given the serious nature of this juvenile offender population.
