This paper presents a comparative analysis of the spatial price cointegration of coffee markets in Ethiopia in the pre and post Ethiopian Commodity Exchange (ECX) era using the autoregressive distributed lag (ARDL) cointegration framework. The study takes into consideration a market condition in which government policy restricts arbitrage coffee trade between coffee producing areas. Using coffee price data from 1998–2013 and applying a bounds test approach and Toda–Yamamoto Granger causality test, the study finds that the establishment of ECX has strengthened regional integration rather than a national harmony between producer markets. We also find evidence that, since the establishment of ECX, an opportunity was created for high quality coffee to dominate price formation while also allowing lower quality coffee producing areas to establish themselves. The study underlines the importance of market transparency and exchange of price information between producer markets.  相似文献

The present investigation focuses on the associations between adolescents’ insecure attachment styles (i.e., anxiety and avoidance) and their autonomous functioning in family decision making. In line with recent insights in the construct of adolescent autonomy, we combined two perspectives on autonomy, differentiating between the degree of independent versus dependent functioning and the self-endorsed and pressuring motives underlying (in)dependent functioning. A longitudinal sample of 327 adolescents (age range = 13–20 years; 64 % girls) completed questionnaires on attachment to the mother and father and on both autonomy operationalisations on two measurement moments spanning a 1-year interval. Structural equation modeling showed that attachment avoidance generally was unrelated to the degree of independent decision making and the motives underlying independent decision making, but related to more pressuring motives for dependent decision making. Anxiety, on the other hand, was associated with a lower degree of independent decision making as well as with more pressuring motives for both independent and dependent decision making. Cross-lagged paths were generally in line with these findings. Theoretical implications are outlined in the discussion.  相似文献

We used three identity processes (i.e., commitment, in-depth exploration, and reconsideration of commitment) from a recently developed model of identity formation to derive empirically identity statuses in a sample of 1952 early and middle adolescents. By means of cluster analysis, we identified five statuses: achievement, foreclosure, moratorium, searching moratorium, and diffusion. Specifically, we found an intra-status differentiation within moratorium, unraveling the positive and negative facets of this status documented in prior literature. The five clusters could be meaningfully distinguished on a number of variables, such as personality features, psychosocial problems, and parental relationships. These findings indicated that a valid distinction in identity statuses could be made in early and middle adolescence. Finally, age and ethnic background strongly affected the distribution of the participants among the five identity statuses. Implications and suggestions for future research are discussed.

This study of early adolescents from the general population examined the direction of effects adolescents’ depressive symptoms, aggression, and perceived parental rejection have on one another in a longitudinal study. Over a four-year period, data were collected yearly from 940 early adolescents (50.6% boys and 49.4% girls) who completed self-report questionnaires of depressive symptoms, aggressive behaviors, and perceived parental rejection. The longitudinal relationships of adolescent reported depressive symptoms, aggression, and perceived parental rejection were tested in multi-group structural equation models. The findings of this study demonstrate that adolescents’ depressive symptoms, aggression, and perceived parental rejection can be viewed as two unidirectional effects models that work in tandem: adolescents’ depressive symptoms longitudinally predicting perceived parental rejection and, in turn, perceived parental rejection longitudinally predicting adolescents’ aggression. Additionally, the strength of these effects diminished as the adolescents grew older and the effects were similar for both adolescent boys and girls.

ABSTRACT

This analysis re-assesses the IMF’s decision to grant debt relief to the DRC in 2010 based on the country’s poverty reduction and growth performance: would the IMF come to the same conclusion given the current knowledge available about the impact of the debt relief process on public governance and service delivery? First, it shows that, whereas the direct resource effect of this aid modality was minimal, the indirect effect was more significant: the conditionalities attached to the process helped to stabilize the economy and increased the overall budget of the Congolese state. This increased resource availability also sustainably percolated to the education sector. Second, however, the impact on social development was minimal: school enrolment increased but was hardly accompanied by extra budget per pupil, whereas more complicated challenges like disparities in access or quality of schooling were left untouched. The government’s strategy was also partly short-circuited by the electoral process.  相似文献

In 2000, the Dutch authorities lifted the ban on brothels in the Netherlands. The essence of their approach was to regulate prostitution. People of legal age could now voluntarily sell and purchase sexual services. Brothels which complied with certain licensing conditions were legalized. This paper critically assesses the logic of a position that argues that human trafficking is reduced when actors in the legalized prostitution sector are made responsible for what happens on their premises (using licensing conditions). This idea is confronted with empirical evidence about the Netherlands in general and the city of Amsterdam in particular. Furthermore, the paper addresses two questions. What are consequences of the regularization of prostitution for the criminal investigation and prosecution of sex trafficking? How do criminal justice agencies collaborate with regulatory authorities in the regulated and non-regulated sectors of the prostitution market? The main conclusion is that the screening of brothel owners and the monitoring of the compliance of licensing conditions do not create levels of transparency that enable sex trafficking to be exposed. The prostitution business retains many characteristics of an illegitimate market and the legalization and regulation of the prostitution sector has not driven out organized crime. On the contrary, fighting sex trafficking using the criminal justice system may even be harder in the legalized prostitution sector.  相似文献

Some explanations of crime among four ethnic groups in the Netherlands   总被引:1,自引:0,他引:1  
Since 1950 there has been large-scale immigration to Western Europe, mainly from Muslim countries. This paper focuses on the degree of involvement in crime of ethnic minority boys as compared to indigenous boys and on the possible causes of these crime involvements. A random sample from three ethnic minority boys (Moroccans, Turks, Surinamese) was taken. A control group consisted of indigenous boys with a comparable socioeconomic background as the minority respondents. Data were gathered about self-report and recorded delinquency, family and school life, leisure time, traditionalism, migration problems, and socioeconomic status. It appears that the arrest rates among the minority youths are substantially higher than among the comparable Dutch boys. A number of explanations are considered: strain, lack of social control, cultural dissonance, and migration problems. Results show that only social control factors explain criminality within the groups, indicating that the causes of criminality among ethnic minority boys may essentially be the same as those among the indigenous boys.  相似文献

This study investigates retrospective voting and issue voting, and their change over time in a transitioning country. Sociotropic, as well as egocentric economic evaluations, and policy issues of parties are expected to play an increasing role in party preferences of citizens over time. Data consist of 41 Hungarian cross-sectional surveys, between 1998 and 2008. Results of conditional logistic regression models reveal that voters reward incumbent parties when they see improvements in their personal or the national economic situation, and punish them if the economy deteriorates. Distance from a given party on the left–right scale also decreases the chance of voting for that party. Voting behavior is changing during transition. The evaluations of the national economy and personal situation have an increasing impact on party preferences over time. We found educational heterogeneity in the extent of economic voting.  相似文献
