Rent-seeking in the classroom and textbooks: Where are we after 50 years?

In this paper, we provide an overview of the influence of Tullock’s work on rent-seeking in the area of economics education. After summarizing the basic rent-seeking model in both a domestic and international context, we conduct an analysis of undergraduate and graduate textbooks in public economics. We find a majority of undergraduate texts cover rent-seeking in depth, but two texts provide zero coverage. No graduate textbook surveyed mentions rent-seeking. We conclude by summarizing the economic education literature on rent-seeking, which can be divided into either classroom experiments or popular culture examples.

     

Facts, Fictions or Reasoning. Law as the Subject Matter of Jurisprudence

This paper deals with the problems involved in the concept of knowledge in the sphere of law. Traditionally, the idea of knowledge has dealt with the presumption of given objects of information. According to this approach, knowing means finding these objects. This is the natural and understandable foundation of metaphysical or philosophical realism. Cognition and cognitive interest are directed outside the sentences by which they are described. This is the point of departure of legal positivism as well. However, it is not possible to see valid law as totally independent of language and concepts. This makes the idea of legal facts as institutional facts vague. From a practical viewpoint, the sentences of judges and legal scholars, when they present valid law, justify rather than describe. Their crucial function is interpretation. Hence, the objectivity of these sentences cannot be based on the presumption of separate objects either. Instead, it has to be based on the principles of acceptable reasoning. Moreover, the author claims that this kind of approach, united with the utilization of human rights and substantial legal principles, leads one to acknowledge objective values.

Cybercrime victimization among young people: a multi-nation study

This study examines cybercrime victimization, what some of the common characteristics of such crimes are and some of the general predictors of cybercrime victimization among teenagers and young adults. A combined four-country sample (Finland, US, Germany and UK; n = 3,506) is constructed from participants aged between 15 and 30 years old. According to the findings, online crime victimization is relatively uncommon (aggregate 6.5% of participants were victims). Slander and threat of violence were the most common forms of victimization and sexual harassment the least common. Male gender, younger age, immigrant background, urban residence, not living with parents, unemployment and less active offline social life were significant predictors for cybercrime victimization.     

Family interaction patterns and the development of social conceptions in the adolescent

The relationship between family interaction and the formation of family and life conceptions in adolescence was studied in an interactional framework. It was hypothesized that openness and constructiveness in family communication and the expression of marital conflicts are positively related to number and content of family and life conceptions. A sex difference was also hypothesized for these conceptions. Fifty-three 15-year-old girls and boys participated in the study. They were interviewed individually and afterward presented with a questionnaire on their family ratings. In addition, most parents—40 mothers and 30 fathers—answered their own questionnaires. The ratings of family interaction by adolescents and parents, respectively, correlated positively, indicating the reliability of the adolescents' ratings. The hypotheses were supported by the results. The richness of family-centered communication and the open expression of marital conflicts together with a positive emotional atmosphere were crucial to the number and content of the adolescents' social conceptions, especially family conceptions.The study is a part of a research project that deals with value orientation in adolescence. The study was supported by a grant to Dr. M. L. Rauste-von Wright from the Council for Social Science Research, the Academy of Finland. The author wishes to express her gratitude to Dr. M. L. Rauste-von Wright.Ph. Lic. in Psychology from University of Turku. Research interests include social development in adolescence, social cognition, and family interaction.     

Typing of XY (male) genotype from malignant neoplastic tissue by the amelogenin-based sex test

DNA profiling of a cancer tissue can be problematic because of genomic instability. Here we have analyzed gastrointestinal cancer specimens from 46 males, of which seven (15%) showed aberrations in determination of gender by the widely used amelogenin test. The X-type amelogenin allele in all cases remained intact. All male tumor samples showing frequent autosomal loss of heterozygosity had a decreased signal of the Y allele from the amelogenin marker. When tested with an alternate set of primers for the amelogenin locus, the Y-type allele showed loss of heterozygosity in the same seven cases. However, when amplified with 15 Y-specific STR primers, all the cancerous tissue Y chromosomes seemed to be intact. These results indicate when malignant neoplastic tissue specimens are used, that amelogenin-based gender determination should be carefully interpreted.     

Dental maturity curves in Finnish children: Demirjian's method revisited and polynomial functions for age estimation

Dental maturity was studied from 2213 dental panoramic radiographs of healthy ethnic Finns from southern Finland, aged between 2 and 19 years. The aim was to provide new Finnish maturity tables and curves and to compare the efficiency of Demirjian's method when differently weighted scores and polynomial regressions are used. The inter-ethnic variations lead us to calculate specific Finnish weighted scores. Demirjian's method gives maturity score as a function of age and seems better adapted for clinicians because, in their case, the maturity score is unknown. Polynomial functions give age as a function of maturity score and are statically adapted for age estimation studies. Finnish dental maturity tables and development curves are given for Demirjian's method and for polynomial functions. Sexual dimorphism is established for the same weighted score for girls and boys, and girls present a greater maturity than boys for all of age groups. Polynomial functions are highly reliable (0.19% of misclassifies) and the percentile method, using Finnish weighted scores, is very accurate (+/- 1.95 years on average, between 2 and 18 years of age). This suggests that polynomial functions are most useful in forensic sciences, while Demirjian's method is most useful for dental health clinicians.     

Triallelic patterns in STR loci used for paternity analysis: evidence for a duplication in chromosome 2 containing the TPOX STR locus

We report triallelic patterns in several short tandem repeat (STR) loci revealed by routine paternity testing using the commercial AMPFlSTR Profiler and AMPFlSTR SGMplus kits. One case where the TPOX-locus (2p25.3) produced three peaks from the blood sample of a child was analysed further. Quantitative polymerase chain reaction (QPCR) and STR typing of the DNAs of the family trio revealed a large (>1.59 Mb) duplication flanking the TPOX-locus in chromosome 2 in both the mother and child. The implications of such genetic anomalies for paternity testing are discussed.
