The economic tradition and the constitution of science

There has been an institutional turn in the philosophy of science, which has led the discipline to become more concerned with understanding how the scientific process actually works. This paper argues that such a philosophy of science, which lies beyond only proposing a logic of science, has something to learn from economics. Economic thinking can be instrumental in understanding the actual scientific process, and in proposing proper institutions guiding scientific competition. It is, however, also argued that economics would benefit from overcoming the pure logic of choice inherent to the neoclassical approach, by further developing the institutional approach to economics.     

Is Public Service Motivation Related to Overall and Dimensional Work-Unit Performance as Indicated by Supervisors?

ABSTRACT

Due to the use of self-reported data and mixed findings, doubts have been raised about the positive relationships found between public service motivation (PSM) and performance. This study aims to provide a robust test of the PSM–performance relationship by using work-unit supervisor ratings, thereby decreasing the risk of common-source bias. Further, this study provides a robustness test by analyzing the relationship between PSM and overall performance, as well as with various dimensions thereof (output, efficiency, service outcome, responsiveness, and resilience). Survey data on employees in 55 work-units of a healthcare organization were analyzed using multiple regression. The results indicate that PSM is significantly related to overall performance but, when regressed on the separate dimensions, PSM is not significantly related to efficiency and responsiveness. The results have implications for both theory and practice as they show that whether PSM relates to performance depends on how performance is conceptualized.     

How school influences adolescents’ conflict styles

The willingness to solve conflicts without violence and to strive for a reconciliation of interests is of central significance for the continued existence of democracies. In this paper, we aim to analyze school-related determinants of adolescents’ conflict behaviour. Models predicting the conflict styles of ‘integrating’, ‘dominating’, ‘avoiding’ and ‘obliging’ were developed drawing on different school climate and school development variables. At the individual level, almost all our hypotheses were confirmed. The highest correlations were found between an open classroom climate and the participation in a class council on the one hand, and an integrating conflict style on the other. On the class level however, most of the anticipated effects did not turn out to be significant. We hope that by providing information about different school climate and school development variables’ impacts on adolescents’ conflict styles, we can contribute to a more effective promotion of constructive conflict behaviour in adolescents.     

Proletarianisation,land, income and living conditions of farm labourers in Kenya

In some areas in Sub‐Saharan Africa, a rural proletariat has emerged, mainly consisting of labourers living and working on plantations and large mixed farms. Besides these ‘full proletarians’, there are also labourers living outside the agricultural estates who perform agricultural wage labour during specific seasons only. Most of these ‘semi‐proletarians’ own a small piece of land. The study analyses the relationship between the degree of proletarianisation on the one hand, and the socio‐economic situation and living conditions of labourers on large farms in Kenya's Trans Nzoia District on the other. In doing so, a comparison is also made with a group of non‐labourers. The conclusion is that a higher degree of proletarianisation coincides with a lower income level but not necessarily poorer living conditions.     

Confessions of a Dinosaur

The old time budget officer has been all but wiped out—the species having been deprived of its natural habitat by the great smoke cloud that began to spread after the great cataclysm of 1974 when the Budget Act began to change all the rules. This, of course, is an overstatement. But it is clear—at least from the perspective of this old dinosaur—that the job of the budget officer has changed over the years, from what many perceived of as a master of financial magic to just another serf (or supervisor) in the bureaucratic feudal system.
This is not a polemic against the Budget Act or the changes that have taken place. The only thing constant about the budget process is change. Rather, it is a discussion of how these changes have affected budget officers over the decades that I have been involved in the budget business.     

Urinary excretion profiles of 11-nor-9-carboxy-Delta9-tetrahydrocannabinol. Study III. A Delta9-THC-COOH to creatinine ratio study

Huestis and Cone reported in [J. Anal. Toxicol. 22 (1998) 445] that serial monitoring of Delta9-THC-COOH/creatinine ratios in paired urine specimens collected at least 24h apart could differentiate new drug use from residual Delta(9)-THC-COOH excretion following acute marijuana use in a controlled setting. The best accuracy (85.4%) for predicting new marijuana use was for a Delta(9)-THC-COOH/creatinine ratio > or = 0.5 (dividing the Delta9-THC-COOH/creatinine ratio of specimen no. 2 by the specimen no. 1 ratio). In previous studies in this laboratory [J. Anal. Toxicol. 23 (1999) 531 and Forensic Sci. Int. 133 (2003) 26], urine specimens were collected from chronic marijuana users > or = 24 h or > = 48 h apart in an uncontrolled setting. Subjects with a history of chronic marijuana use were screened for cannabinoids with the EMIT II Plus cannabinoids assay (cut-off 50 ng/ml) followed by confirmation for Delta9-THC-COOH by GC-MS (cut-off 15 ng/ml). Creatinine was analyzed as an index of dilution. The objective of the present study was to evaluate whether creatinine corrected specimens could differentiate new marijuana or hashish use from the excretion of residual Delta(9)-THC-COOH in chronic marijuana users based on the Huestis 0.5 ratio. Urine specimens (N=376) were collected from 29 individuals > or = 96 h between urine collections. The mean urinary Delta9-THC-COOH concentration was 464.4 ng/ml, mean Delta9-THC-COOH/creatinine ratio (ng/(ml Delta9-THC-COOH mmoll creatinine)) was 36.8 and the overall mean Delta9-THC-COOH/creatinine ratio of specimen 2/mean Delta9-THC-COOH/creatinine ratio of specimen 1 was 1.37. The Huestis ratio calculation indicated new drug use in 83% of all sequentially paired urine specimens. The data were sub-divided into three groups (Groups A-C) based on mean Delta9-THC-COOH/creatinine values. Interindividual mean Delta9-THC-COOH/creatinine values ranged from 4.7 to 13.4 in Group A where 80% of paired specimens indicated new drug use (N=10) and 20.4-39.6 in Group B where 83.6% of paired specimens indicated new drug use (N=7). Individual mean Delta9-THC-COOH/creatinine values ranged from 44.2 to 120.2 in Group C where 84.5% of paired urine specimens indicated new marijuana use (N=12). Correcting Delta9-THC-COOH excretion for urinary dilution and comparing Delta9-THC-COOH/creatinine concentration ratios of sequentially paired specimens (collected > or = 96 h apart) may provide an objective indicator of ongoing marijuana or hashish use in this population.     

Victimized in Amsterdam: The organized reaction

This article deals with the effects of a unique victim assistance project for victimized tourists, the Amsterdam Tourist Assistance Service (ATAS). ATAS intervention turns out to have a direct impact on victims to the extend that the negative consequences or the victims are reduced. Besides, ATAS intervention has a function on repairing Amsterdam's image that probably was damaged aftre the victimization.

What Friends are for: The Relationships Between Body Image, Substance Use, and Peer Influence Among Finnish Adolescents

The study investigated the relationships between substance use, body image, and peer influence among Finnish adolescents. The participants (N=488, 240 boys and 248 girls), were eighth-grade high school students. The data were gathered using a questionnaire. In addition to background information, the study covered risk behaviors frequency, body satisfaction, and peer relationships. The results indicated that the levels of body satisfaction among the adolescent girls studied were lower than those among the adolescent boys. It was found that the girls engaged in more discussion with peers than the boys concerning both intimate and general matters. Moreover, having an intimate relationship with one's peers was associated with a greater tendency to drink purely in order to get drunk. However, a slightly more distant relationship with friends was associated with a greater risk for smoking. In general, dissatisfaction with one's physical appearance seemed to relate to substance use. By highlighting the relationships between adolescents’ body image, substance use, and peer influence the study gives pointers for further research, and may be suggestive in terms of the kinds of social policies that ought to be pursued in the future.MA (Educational Sciences) from the University of Turku.
