‘The cloak of competence’: Assessment dilemmas in social work education

In the face of administrative and pedagogic changes in professional social work training, educators and trainers face considerable uncertainty. Key dilemmas concern what is meant by competence, and how far it is possible to identify and reconcile technical and ideological competencies. This paper uses empirical material from a semi-participant study to explore the relevance of the concept ‘cloak of competence’, with reference to the behaviour of tutors and practice teachers. It suggests that excessive or continuous uncertainty generates avoidance or coping strategies, which lead to a resolution by the achievement of an appearance of competence. The consequences of these processes for staff development are then briefly considered.

Institutional Diversity and Performance in African Cotton Sectors

This article analyses the performance of cotton sectors across East, Southern, and West Africa, paying particular attention to the wide diversity of institutional arrangements that they now exhibit. It finds strong support for earlier contentions regarding trade‐offs between competition and coordination, and between the roles of public and private sectors. New insights provide concrete and context‐specific guidance to policy‐makers and stakeholders regarding the key challenges they will face and the risks they will need to manage as they work to improve productivity and ensure an equitable division of benefits within cotton sectors.     

纳西英雄之名的翻译:从民族文学到世界文学

In ethnic minority literature, the translation of names plays an important role in sha-ping ethnic identity. The names of an ethnic group’s folk heroes,in this case the Naxi hero Coqsseileel’ee ( in Naxi pinyin ) , or ( in Interna-tional Phonetic Alphabet ) , are not just sound se-quences, but are also full of implicit meaning that needs to be transferred. Only when this meaning is conveyed can we protect ethnic culture in transla-tion.     

Probabilistic Reliability Modeling for Oil Exploration & Production (E&P) Facilities in the Tallgrass Prairie Preserve

The aging domestic oil production infrastructure represents a high risk to the environment because of the type of fluids being handled (oil and brine) and the potential for accidental release of these fluids into sensitive ecosystems. Currently, there is not a quantitative risk model directly applicable to onshore oil exploration and production (E&P) facilities. We report on a probabilistic reliability model created for onshore exploration and production (E&P) facilities. Reliability theory, failure modes and effects analysis (FMEA), and event trees were used to develop the model estimates of the failure probability of typical oil production equipment. Monte Carlo simulation was used to translate uncertainty in input parameter values to uncertainty in the model output. The predicted failure rates were calibrated to available failure rate information by adjusting probability density function parameters used as random variates in the Monte Carlo simulations. The mean and standard deviation of normal variate distributions from which the Weibull distribution characteristic life was chosen were used as adjustable parameters in the model calibration. The model was applied to oil production leases in the Tallgrass Prairie Preserve, Oklahoma. We present the estimated failure probability due to the combination of the most significant failure modes associated with each type of equipment (pumps, tanks, and pipes). The results show that the estimated probability of failure for tanks is about the same as that for pipes, but that pumps have much lower failure probability. The model can provide necessary equipment reliability information for proactive risk management at the lease level by providing quantitative information to base allocation of maintenance resources to high-risk equipment that will minimize both lost production and ecosystem damage.     

Never the Right Age? Gender and Age‐Based Discrimination in Employment

Although UK legislation against age discrimination is required by December 2006, little is yet known about how ageism affects different age categories of employees, and the gender dimensions of ageism have also been neglected. Both issues were investigated by questionnaire survey, producing responses from over 1000 employees of a major UK financial services enterprise. The extent and manifestations of ageism were found to vary across age categories and by sex, and evidence of gendered ageism emerged. Reported examples of ageism were highest among younger and older age categories, but all age groups were affected to some degree. Across all ages, women were more likely than men to experience ageist attitudes concerning appearance or sexuality. To be effective, legislation will need to cater for the complex nature and patterns of age discrimination revealed, though the comparator problem and other complexities are such that important aspects of age prejudice, including gender dimensions, risk being overlooked.
