Experiences with and the viability of a recycling pilot project in a Cape Town township

This paper documents the experience with an NGO-initiated recycling programme in Hangberg Township, Cape Town. The 11-week trial project achieved 70% sign-up but suffered substantial drop-out. The NGO’s attempt to brand block leaders as ‘eco-heroes’ was unsuccessful and there were concerns about the distribution of project benefits. The project diverted 26% by mass of the estimated solid waste refuse stream of 2.5 kg per person per week and made R1752 from selling 1.965 tons of recycling. Some 970 kg of compostables were diverted but not processed as part of the project. Project accounts revealed a benefit–cost ratio of 0.123 in which the sale of recyclables and landfill costs avoided were the only benefits and wages and consumables the main costs. While a more equitable distribution of benefits could improve the cost–benefit ratio, there are other good reasons for donors to fund projects of this nature.     

School composition effects in Denmark: quantile regression evidence from PISA 2000

Data from the first wave of the OECD PISA study are combined with register data for Denmark to estimate the effect of the socioeconomic mix of schools on students’ test scores. A major disadvantage of the PISA design for the analysis of school composition effects is the small students-per-school samples. Adding family background data from administrative registers for all same-aged schoolmates of the PISA students helps overcome this. To compensate for endogeneity in the school composition variable, the results are conditioned on a rich set of family and school variables from the PISA data. Quantile regression results suggest differential school composition effects across the conditional reading score distribution, with students in the lower quantiles achieving the largest test score gains. Mathematics results suggest that high- and low-ability students benefit equally from attending schools with a better student intake, and most results for science are only marginally significant. These results imply that mixing students of different home backgrounds could improve equity of achievement for both reading and mathematics; however, the average skill level would improve only for reading literacy. In mathematics, mixing students would not raise average outcomes, because the detrimental effect on students in the higher quantiles would offset positive effects on those in the lower quantiles.

Employability enhancement through formal and informal learning: an empirical study among Dutch non‐academic university staff members

Although learning is generally perceived as a way to improve employees' current job performance, so far, no research has been conducted to explore the possible relationships between formal and informal learning, on the one hand, and employability, on the other. Though contemporary views stress the importance of the job as a powerful learning site, considerable research evidence underpinning these views is lacking. This paper goes into the impact of formal and informal learning upon employability. The influence of employee characteristics and organizational factors is also taken into account. An e‐questionnaire was used to collect data among 215 Dutch non‐academic university staff members. Our findings emphasize the necessity of Human Resource Development strategies that encompass a mix of formal and informal learning opportunities. In particular, participation in networks appears to be an important predictor for employability. With the outcomes of this study, we aim to contribute to the further development of theoretical insights regarding employability enhancement through learning possibilities embedded in the workplace. It seems that strategies that focus exclusively on enhancing informal on‐the‐job learning should not be encouraged. Our study is limited to one context and further research is required to investigate the generalizability of the findings to other occupations and/or countries.     

The Assessment of Information Technology Maturity in Emergency Response Organizations

In emergency response organizations, information technologies are not adequately explored. Sometimes, the mere adoption of new information technologies is not productive, as their efficient use depends on other interrelated technologies and the environment where they are installed. This work describes a model to help organizations understand their capability in respect to the adoption of these technologies. The model also helps the performing of the evaluation from different perspectives, making it suitable to collaborative evaluation. Using the proposed model, an organization can measure its maturity level in different aspects of the evaluation and guide the investment on its capabilities. Part of the model has been developed for emergency response organizations and the information technology dimension of the model has been applied to two fire department installations.     

Job insecurity and intent to leave the nursing profession in Europe

To determine the occupational factors affecting nurses' decision to leave their profession before reaching retirement age, a large epidemiological study (Nurses' early exit study – NEXT)1 1. EU-financed project QLK6-CT-2001-00475. was carried out in ten European countries. Altogether 32,037 registered nurses answered a questionnaire, covering, for example, questions on job insecurity and intention to leave nursing work. The data were analysed statistically using Chi² test and binary logistic regression models.

Concern about becoming unemployed and difficulties to find a new job if laid off was reported by 40% of the respondents. More than half of the respondents were worried about their qualitative job security (being transferred to another job or changes in work schedule), while less than 40% had concerns about becoming unable to work. Thoughts about leaving the profession were reported by 15% of the respondents.

The hypothesis, that nurses will show higher intention to leave if they experience high levels of job insecurity, was partly supported by the results of the study. The concern about the qualitative aspects of job security correlated positively with intent to leave nursing in almost all the participating countries; most strongly among the Finnish and Norwegian nurses. The relationship between the concern about employment security and intent to leave varied from country to country, probably due to differences in the labour market situation. The correlation was positive for the Dutch and British nurses while, for the Polish and German sample, nurses who reported worry about their employment security appeared to be less willing to leave the profession than those who were not too worried. The concern about being unable to work correlated positively with intent to leave in several countries, reflecting the demands of the profession.

The effects of job insecurity can be reduced if nurses feel that they are important to the health care institution they work for, and that the institution cares about them, and values their opinion.     

Strategic alliance team diversity,coordination, and effectiveness

Drawing upon literatures on strategic alliances, teams, and diversity, we propose that strategic alliance team diversity warrants further examination. We suggest that strategic alliance team coordination moderates the relationship between strategic alliance team diversity and effectiveness. Specifically, we hypothesize that coordination strengthens the negative relationship between observable diversity characteristics of nationality and gender and team effectiveness. We also argue that coordination strengthens the positive relationship between nonobservable diversity characteristic of functional background and team effectiveness. Results from 109 team members, 44 team leaders, and 34 alliance executives involved with 44 strategic alliance teams in 15 firms partially support our hypotheses.     

Associations between perceived employability,employee well-being,and its contribution to organizational success: a matter of psychological contracts?

We investigated interactions between perceived employability and employees' perceptions about psychological contract obligations made by the employer in relation to life and job satisfaction, self-rated performance, and turnover intention. We hypothesized that perceived employability relates positively to job satisfaction, life satisfaction, and self-rated performance and negatively to turnover intention under the condition of many promises. Conversely, perceived employability relates negatively to job satisfaction, life satisfaction, and self-rated performance and positively to turnover intention under the condition of few promises. Analyses using a sample of 463 workers from seven Belgian organizations showed that perceived employability was positively related to all outcomes except job satisfaction. The number of promises was positively related to job and life satisfaction, and to self-rated performance, and negatively to turnover intention. Contradictory to our expectations, with the exception of turnover intention, the relationships between perceived employability and the outcomes were relatively stronger and positive under the condition of few promises compared with many promises.     

Optimal portfolio selection via conditional convex risk measures on L p

We consider conditional convex risk measures on L ^p and show their robust representation in a standard way. Such measures are used as evaluation functionals for optimal portfolio selection in a Black&Scholes setting. We study this problem focusing on the conditional Average Value at Risk and the conditional entropic risk measure and compare the respective optimizers.
