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.     

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.     

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.     

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.     

Resignifying Alan Kurdi: news photographs,memes, and the ethics of embodied vulnerability

The Turkish photojournalist Nilüfer Demir’s photograph of the drowned refugee child Alan Kurdi attained worldwide recognition as a media spectacle, initially prompting humanitarian responses and political action, but later morphing into online memes and inciting public backlash as “war porn.” The author argues here that the ethical motivations of photojournalism and memes are oppositional with regard to their representations of embodied vulnerability. While photojournalistic depictions of vulnerable bodies are motivated by an ethics of care intended to generate empathy and progressive social change, memes disrupt those affective connotations through processes of mimicry and replication. By means of a comparative semiological analysis, this paper examines the way the sign system of Demir’s photograph was mutated into memes, radically changing the ethical connotations of the former. The differing ethical affordances of news photos versus memes, and their relationship, explain the reversal of the cosmopolitan humanitarianism initially sparked by the Alan Kurdi photograph and tell us more about the ethical frictions and contrapositions at work in the contemporary media environment.     

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.

Adoptions: Follow-up from an orphanage in Bombay

The practice of adoption, though long accepted as a social phenomenon, is only recently gaining popularity in India. Due to the paucity of adequate follow-ups, evaluation of these adopted children is incomplete. For the purpose of studying the well-being of these children after adoption, they were followed-up at the various places, i.e., orphanages, institutions, juvenile courts and adoption agencies, responsible for their care. One hundred sixty children, 63 boys and 97 girls, adopted from an orphanage in the vicinity of our hospital over a period of 13 years are included in this study. There were 104 local and 56 foreign adoptions. Due to sociocultural background in Indian adoptions, males were preferred; whereas the international adoptions mostly depended on human considerations without any specific preference for the sex of the child. On follow-up, all children except three were reported to be physically healthy and well-adjusted emotionally in the new family, and well accepted by the society. Although adoption is not the only solution for an abandoned child, it may open some avenues for the betterment of socially deserted and deprived children.     

A biologically active constituent of withania somnifera (ashwagandha) with antistress activity

In Ayurvedic medicine,Withania somnifera (Ashwagandha) is well known for its anti-stress activity. A passive rat experimental model, where the animals are subjected to multiple stress of cold, hypoxia, restraint (C-H-R) has been developed to evaluate adaptogenic properties of various fractions of W. somnifera root extracts. We have carried out extraction of roots of W. somnifera with water and further isolated one of the active constituents called compound X and also tested its anti-stress activity in C-H-R model. The effect of administration of W. somnifera water suspension (360 mg/Kg bw) and compound X (20mg/Kg bw) on the fall and recovery of colonic temperature was noted. There was an increase of ≈38% and ≈54% in the time taken to attain T_rec 23°C by rats given a single dose of fresh aqueous suspension and biologically active constituent (Compound X) respectively, where as decrease in the recovery time to attain T_rec 37°C is ≈13% and ≈33% respectively, as compared to control group. It is clear that rats treated with the fresh aqueous suspension and compound X ofWithania somnifera, could withstand the multiple stress of C-H-R better than control group.
