The developmental costs of high self-esteem for antisocial children

Two hypotheses--high self-esteem leads children to act on antisocial cognitions (disposition-activating hypothesis) and high self-esteem leads children to rationalize antisocial conduct (disposition-rationalizing hypothesis)--were investigated in two longitudinal studies. In Study 1 (N= 189; mean age = 11.1 years), antisocial behavior was aggression; in Study 2 (N= 407; mean age = 10.8 years) it was avoidance of the mother. In both studies, there was little evidence for the disposition-activating hypothesis but considerable support for the disposition-rationalizing hypothesis. Over time, aggressive children with high self-esteem increasingly valued the rewards that aggression offers and belittled their victims, and avoidant children with high self-esteem increasingly viewed their mother as harassing and uninvolved. For antisocial children, high self-esteem carries costs.     

The economic benefits of higher education in Cyprus: The expectations of prospective students

The paper investigates the economic benefits and costs of higher education as these are perceived by higher education candidates and labour market entrants in Cyprus. It provides further evidence on the topic after a similar study which preceded the present project by 10 years. Perceived rates of return to education are presented for two points in time, namely, 1993 and 2003. The findings point to an increasing awareness of the link between education and earnings on the part of young people, which can be linked to the country's economic development. The main influences on the respondents’ expected lifetime earnings are examined through multiple regression analysis. Gender and ability are found to be significantly related to expected earnings.     

Students’ expectations about earnings and employment and the experience of recent university graduates: Evidence from Cyprus

The employability of university graduates constitutes a major policy concern in both developed and developing nations. In this context, the present study uses self-reported data to compare the earnings and employment expectations of university students, and the realised earnings and employment paths of recent graduates. The sample consisted of 476 individuals (243 students and 233 graduates of the University of Cyprus). The analysis points to both differences and similarities in the effect of different variables on (a) the probability of employment for graduates and the probability of expected employment for students, and (b) the conditional salary of graduates and the conditional expected salary of students. The completion of postgraduate studies, the area of family residence and the department of study are the key factors affecting the graduates’ employment probability, while the students’ probability of expected employment is determined differently, namely by characteristics such as secondary education performance and studies in the business administration department. Gender and family income are among the main determinants of both the graduates’ actual earnings and the students’ expected earnings, with women earning or expecting to earn less than men, and graduates/students with higher family incomes earning or anticipating to earn more than their lower income counterparts. The findings are compared to those of similar studies in other countries.     

Free final time fractional optimal control problems

A formulation and solution scheme of free final time fractional optimal control problems is presented in this paper. The dynamic constraint is described by a fractional differential equation. Performance index considered is a function of both the state and control variables. The necessary conditions of optimality and the transversality condition are obtained using Lagrange multiplier technique. A numerical technique similar to Shooting method is used for solving the optimal conditions. Numerical example is provided to show the effectiveness of the formulation and numerical solution scheme. It is interesting to note that the final time changes with the interchange of the boundary conditions, which does not occur in classical optimal control problems.     

Managing the link between higher education and the labour market: perceptions of graduates in Greece and Cyprus

Abstract

The paper investigates the experience of employed higher education graduates in two countries with high rates of graduate unemployment. It examines the employment experience of graduates and their perceptions regarding the contribution of higher education to their employment and career prospects. Qualitative research was used to collect information from 58 university graduates in two Southern European countries, Greece and Cyprus. Respondents provided information on the skills and competencies acquired through higher education and utilised in the world of work. In both countries, modest links were reported between jobs and graduates’ field of study, as well as between knowledge and non-knowledge-based competencies acquired through higher education, and the requirements of the graduates’ jobs. The findings are used as the basis for suggestions that can enhance graduate employability and contribute to the management of the link between higher education and the labour market.     

Perceived rates of return to higher education in Cyprus

The paper estimates perceived rates of return to higher education in Cyprus and uses them in logistic regression analysis in order to study the effect of economic considerations on the decision of secondary school pupils to pursue higher education. Unlike earlier studies, the data used in the computation of these rates are based wholly on the pupils' subjective estimates. The results are supportive of human capital theory: The mean rate of return to higher education estimated by higher education candidates is considerably higher than that perceived by labour market entrants. Logistic regression analysis shows the percieved rate of return to higher education, as estimated by both the elaborate and the short-cut methods, to have a significant effect on the pupils' educational intentions.     

Protective role of N-acetylcysteine against alcohol and paracetamol induced toxicity

The effect of administration of N-acetylcysteine on ethanol and paracetamol induced hepatotoxicity was studied both biochemically and histopathologically in experimental rats. The liver samples taken after twentyfour hours from the paracetamol administered normal and alcoholic animals showed high degree of necrosis and related pathological changes. In the N-acetylcysteine treated alcoholic rats and in the N-acetylcysteine pretreated paracetamol administered rats, the liver cells showed very little change and appeared almost normal as evidenced by the histopathological studies. The activities of serum transaminases and phosphatases were also high both in the alcohol treated and in the paracetamol administered animals. N-acetylcysteine treated animals partly restored the serum transaminase and phosphatase activities, and the activities of the antiperoxidative enzymes. There was also significant change in the serum and tissue lipid levels, and in the concentration of the tissue lipid peroxidation product-malondialdehyde in both the alcohol treated and in the paracetamol administered groups. N-acetylcysteine treatment brought the serum and tissue lipid levels, and the tissue malondialdehyde content towards normal.     

Factors influencing the demand for higher education: The case of Cyprus

The proportion of young people opting for third level education in Cyprus is exceptionally high, currently about 60% of the relevant age group. This has caused concern among the country's policy makers who are aware of the limited capacity of the Cyprus economy to accommodate the increasing supply of higher education graduates. In the present study, an attempt is made to identify and examine the factors influencing young Cypriots to select higher education over direct employment at the end of their secondary education. A survey was conducted among 811 final form secondary school students in Cyprus in the academic year 1993/1994. Through factor analysis, seven factors with a potential effect on the students' educational and occupational intentions were identified. They were the following: Psychological/Individual, Occupational I, Occupational II, Economic, Consumption, Secondary School Subjects, and Significant Others. These factors, along with a number of student background characteristics (gender, socioeconomic status, ability, and secondary school specialisation) were used as explanatory variables in a logistic regression model with the student's educational intentions serving as the dependent variable. The psychological/individual factor, the second occupational factor, and secondary school specialisation were shown to have a significant effect on the intention to pursue third level education. The paper points to the importance of analysing and examining student characteristics and motivational patterns in the effort to understand, and, if possible, influence trends in the demand for higher education.     

Perceptions of future and cur rent teachers on the organization of elementary schools: a dissonance approach to the investigation of job satisfaction

The study compares the satisfaction ratings of future and current elementary school teachers with respect to the main aspects of school organization and administration. Data were collected from 66 in-service teachers and 79 preservice teachers in Cyprus. The application of factor analysis on the data resulted in the identification of the following main dimensions of school organization: headmaster's role, school organization, school climate, teacher incentives/work conditions, inspector's role and teachers' role. The comparison of the satisfaction ratings of future and current teachers on the above factors produced the following findings: first, the ratings of the two groups differed significantly for the first four factors. Secondly, future teachers reported lower satisfaction ratings than their in-service counterparts in the headmaster's role, school organization and school climate factors and higher ratings on the teacher incentives/work conditions factor.These discrepancies are considered to constitute causes of concern for educational policy-makers. The high expectations of future teachers on the teacher incentives/work conditions factor are viewed as a probable subsequent cause of cognitive dissonance and job dissatisfaction. On the other hand, the low expectations of future teachers with respect to three factors (headmaster's role, school organization, school climate) are likely to reduce their initial enthusiasm for their job. The implications of the findings for teacher training programmes are discussed, and suggestions are made on ways of reducing discrepancies between the expectations of future teachers and the realities of the workplace.
