Back to the forest: exploring forest transitions in Candelaria Loxicha, Mexico

Declining profitability of agriculture and/or higher prices of forest products and services typically drive an increase in forest cover. This article examines changes in forest cover in Candelaria Loxicha, Mexico. Forest cover increased in the area as a result of coffee cultivation in coffee forest-garden systems. Dependence on forest products and services, and not prices of forest products, drive the process in our study site. Low international coffee prices and high labor demand outside the community might pull farmers out of agriculture, but they do not completely abandon the lands. A diversification in income sources prevents land abandonment and contributes to maintaining rural populations and coffee forest gardens.     

Fear of Crime Revisited: Examining the Direct and Indirect Effects of Disorder,Risk Perception,and Social Capital

Fear of crime has long been considered a significant social problem, spurring decades of academic research and leading to a variety of policy initiatives. Building on prior research, this study investigated the direct and indirect effects of demographic characteristics, social and physical disorder, and prior victimization on fear of crime. Further, it assessed the direct and indirect effects of perceived risk on fear. Finally, the research examined the extent to which social capital mediated the impact of these variables on fear. Using data from a survey of residents in a southeastern city, analyses reveal that victimization and disorder significantly predict fear of crime, and that risk perception and social capital mediate the relationship between disorder and victimization on fear. Further, structural equation models show a number of interesting indirect effects. Policy implications and directions for future research are discussed.     

Toward a concept of psychosocial maturity

Schools below the college level traditionally have been preoccupied with only one outcome of education: growth in measurable cognitive skills. While there is at present a growing recognition of the school's actual and potential role in promoting personal and social growth, a convincing model of nonacademic objectives is lacking, as is a tool for assessing children's progress toward nonacademic objectives. To this end, the authors construct a model of psychosocial maturity which specifies measurable attitudes and dispositions. The model of psychosocial maturity integrates sociological and psychological views of the person; that is, it takes into account the requirements of societies as well as the healthy development of individuals. The model outlines three general dimensions of maturity which are likely to be relevant in all societies. These are (1) the capacity to function adequately on one's own, (2) the capacity to interact adequately with others, and (3) the capacity to contribute to social cohesion. Nine attributes judged pertinent to these capacities in this society are then defined. The final sections of the paper discuss problems in the measurement of psychosocial maturity, describe the form of an instrument presently being devised, and suggest research uses of the instrument.Preparation of this paper was supported by funds from The National Institute of Education, Contract No. NE-C-00-3-0013.Received his Ph.D. trom Radeliffe College.

Trust in a Time of Increasing Diversity: On the Relationship between Ethnic Heterogeneity and Social Trust in Denmark from 1979 until Today

This article examines the impact of ethnic diversity in Danish municipalities on citizens' social trust over the last three decades. During this period, Danish society has grown increasingly ethnically diverse, and this begs the question whether this has influenced trust in others negatively. Existing evidence from the Anglo‐Saxon countries would suggest that this is the case, whereas evidence from the European continent mainly suggests that no link exists between ethnic diversity and social trust. The empirical analysis uses individual‐level data on social trust from several surveys in Denmark in the period from 1979 to 2009 coupled with diversity at the municipality level. Individual‐level measures of trust over time enable estimation of the impact of changes in ethnic diversity within municipalities on social trust and, it is argued, thereby a more precise estimate of the effect of ethnic diversity on trust. The results suggest that social trust is negatively affected by ethnic diversity. The article concludes by discussing this result and suggest avenues for further research.     

Impairment based legislative limits for driving under the influence of non-alcohol drugs in Norway

Bloodstains at crime scenes are among the most important types of evidence for forensic investigators. They can be used for DNA-profiling for verifying the suspect's identity or for pattern analysis in order to reconstruct the crime. However, until now, using bloodstains to determine the time elapsed since the crime was committed is still not possible. From a criminalistic point of view, an accurate estimation of when the crime was committed enables to verify witnesses' statements, limits the number of suspects and assesses alibis. Despite several attempts and exploration of many technologies during a century, no method has been materialized into forensic practice. This review gives an overview of an extensive search in scientific literature of techniques that address the quest for age determination of bloodstains. We found that most techniques are complementary to each other, in short as well as long term age determination. Techniques are compared concerning their sensitivity for short and long term ageing of bloodstains and concerning their possible applicability to be used on a crime scene. In addition, experimental challenges like substrate variation, interdonor variation and environmental influences are addressed. Comparison of these techniques contributes to our knowledge of the physics and biochemistry in an ageing bloodstain. Further improvement and incorporation of environmental factors are necessary to enable age determination of bloodstains to be acceptable in court.     

The PMMA epidemic in Norway: comparison of fatal and non-fatal intoxications

During a 6 month period (July 2010-January 2011) we observed 12 fatal intoxications and 22 non-fatal cases related to the drug paramethoxymethamphetamine (PMMA) in Norway (4.8 mill inhabitants). This toxic designer drug, also known as "Death", is occasionally found in street drugs offered as "ecstasy" or "amphetamine". The present study aimed to evaluate the cause of death, and to compare the PMMA blood concentrations in fatal and non-fatal cases. Methods for identification and quantification of PMMA are presented. The median age of fatalities was 30 years (range 15-50) with 67% males; in non-fatal cases 27 years (20-47) with 86% males. In the 12 fatalities, the median PMMA blood concentration was 1.92 mg/L (range 0.17-3.30), which is in the reported lethal range of 0.6-3.1 mg/L in peripheral blood and 1.2-15.8 mg/L in heart blood. In the 22 non-fatal cases, the median PMMA concentration was 0.07 mg/L (range 0.01-0.65). Poly-drug use was frequent both in fatal and non-fatal cases. The PMA concentrations ranging from 0.00 to 0.26 mg/L in both groups likely represented a PMMA metabolite. Three fatalities were attributed to PMMA only, six to PMMA and other psychostimulant drugs, and three to PMMA and CNS depressant drugs, with median PMMA concentrations of 3.05 mg/L (range 1.58-3.30), 2.56 (1.52-3.23) and 0.52 mg/L (0.17-1.24), respectively. Eight victims were found dead, while death was witnessed in four cases, with symptoms of acute respiratory distress, hyperthermia, cardiac arrest, convulsions, sudden collapse and/or multiple organ failure. In summary, all fatalities attributed to PMMA had high PMMA blood concentrations compared to non-fatal cases. Our sample size was too small to evaluate a possible impact of poly-drug use. A public warning is warranted against use and overdose with illegal "ecstasy" or "speed" drugs.     

Morphine to codeine concentration ratio in blood and urine as a marker of illicit heroin use in forensic autopsy samples

A morphine to codeine ratio greater than unity (M/C>1) has been suggested as an indicator of heroin use in living individuals. The aim of this study was to examine the morphine to codeine ratio in a large population (N=2438) of forensically examined autopsy cases positive for 6-monoacetylmorphine (6-MAM) and/or morphine in blood and/or urine. Blood and urine concentrations of 6-MAM, morphine and codeine were examined using GC-MS and LC-MS/MS methods. In 6-MAM positive samples, the M/C ratio was greater than unity in 98% (N=917) of the blood samples and 96% (N=665) of the urine samples. Stratification of 6-MAM negative cases by M/C above or below unity revealed similarities in morphine and codeine concentrations in cases where M/C>1 and 6-MAM positive cases. Median blood and urine morphine concentrations were 8-10 times greater than codeine for both groups. Similarly to 6-MAM positive cases, 25-44 year-old men prevailed in the M/C>1 group. In comparison to cases where M/C ≤ 1, the M/C ratio was a hundred times higher in both 6-MAM positive and M/C>1 cases. The range of morphine concentration between the lowest and the highest quintile of codeine in M/C>1 cases was similar to that in 6-MAM positive cases. This range was much higher than for M/C ≤ 1 cases. Moreover, linear regression analyses, adjusted for age and gender, revealed a strong positive association between morphine and codeine in 6-MAM positive and M/C>1 cases. The M/C ratio appeared to be a good marker of heroin use in post-mortem cases. Both blood and urine M/C>1 can be used to separate heroin users from other cases positive for morphine and codeine.     

Biting the hand that feeds them? Abkhazia–Russia client–patron relations

ABSTRACT

The article discusses the post-Soviet de facto state of Abkhazia, and its relationship to its main patron, Russia. All patron–client nexuses are marked by a high degree of asymmetrical power – especially with de facto states, which depend upon the patron for their very survival. Thus, it is surprising to see how de facto client states repeatedly show that they are both willing and able to defy the wishes of their patrons and pursue their own agendas instead. Moreover, the patron may be willing to tolerate such rebelliousness. What can explain such “disobedient” behavior? I examine three contentious aspects of Russian–Abkhazian relations: the process leading up to the signing of an extended bilateral agreement in 2014; the tussles over how to fight crime in Abkhazia; and acrimony over Abkhazia’s reluctance to allow Russians to buy property in their country, despite massive pressure from Russian authorities.
