AbstractCoptotermes intermedius is a damp-wood subterranean termite, which attacks timber and other woody materials with heavy losses in the southern part of Nigeria. The process leading to search for wood and eventual damage was investigated, with focus on how this search is initiated and by which of the termite castes. Results showed that minor soldiers initiate the exploratory phase of search, while the workers are involved in the eventual recruitment process. Under appropriate soldier-worker caste ratio or percentages, exploratory activities in C. intermedius may be regulated.

It has been estimated that graphology is used by over 80% of European companies as part of their personnel recruitment process. And yet, after over three decades of research into the validity of graphology as a means of assessing personality, we are left with a legacy of equivocal results. For every experiment that has provided evidence to show that graphologists are able to identify personality traits from features of handwriting, there are just as many to show that, under rigorously controlled conditions, graphologists perform no better than chance expectations. In light of this confusion, this paper takes a different approach to the subject by focusing on the rationale and modus operandi of graphology. When we take a closer look at the academic literature, we note that there is no discussion of the actual rules by which graphologists make their assessments of personality from handwriting samples. Examination of these rules reveals a practice founded upon analogy, symbolism, and metaphor in the absence of empirical studies that have established the associations between particular features of handwriting and personality traits proposed by graphologists. These rules guide both popular graphology and that practiced by professional graphologists in personnel selection.

Recently the university students are required by their institutions to have the TOEFL score in the fisrt year or in the last year of their study before graduation. Some other higher institutions require their students to submit TOEIC, not TOEFL, before graduation. Companies, in the recruitment process, require the applicants to submit TOEFL score to show their level of English proficiency. The first question is which one is more appropriate for job applicants in the compay: TOEFL  or TOEIC. Another question for university students before graduation is whether to have TOEFL  in the first year or in the last year before graduation. This article aims at answering the two questions raised. The first part will give an overview of various versions of TOEFL  and  TOEIC  and the second part proposes the appropriate English proficiency test  for the recruitment process for new employees and for the university graduates, that is, TOEIC for the company  and TOEFL  for universities  and  colleges.

Fungi have a great diversity and wide distribution at the world. It can be used as the alternative technology for controlling of subterranean termite attack, particularly genus Coptotermes knowned as the wooden destructive organism, by using entomophatogenic fungi. For the purpose of the study, several isolate sources were taken from some locations. The results show that eight numbers of pathogenic fungi was founded by screening and identification of fungi taken from 19 numbers of isolate sources. The pathogenic fungi were Beauveria sp., Penicillium brevicompactum, P. rubrum, Paecilomyces fulvus, Fusarium verticolloides, Pythium sp., and Aspergillus sp. Key words: Jamur entomopatogen, Coptotermes sp.

The landscape of paid domestic work has changed considerably in recent years with the growth in the number of housecleaning service companies in South Africa and elsewhere. Housecleaning service companies transform domestic work into a service economy where trained domestic workers render a professional cleaning service to clients. In South Africa, little is known about the factors that employers at housecleaning service companies take into consideration during the selection and recruitment process. A key feature of paid domestic work is the gender, class and race constructions of domestic workers, the vast majority of whom are women, usually women of colour, from low socio-economic backgrounds. Whether we are seeing a change in the demographic profile of domestic workers with the growth of housecleaning service companies remains unclear. This paper therefore focuses on the recruitment strategies of employers at selected housecleaning service companies in Johannesburg in an attempt to shed light on the challenges that jobseeking domestic workers may face. Open-ended interviews with managers revealed that gender, race, age, long-term unemployment, and technical and personal skills of job-seeking domestic workers have a strong impact on the recruitment process, while immigration status plays a somewhat reduced role. This paper concludes that housecleaning service companies have not changed the demographic profile of domestic workers in South Africa yet, and that paid domestic work is still predominantly a black woman’s job.

Several studies have demonstrated the biological efficacy of leaf, stem and root powders or extracts of Chromolaena odorata (L.) King and Robinson against insect pests but those that are focused on the biological efficacy of aqueous leaf extracts against Macrotermes species are scanty. Current management of termites with synthetic insecticides is being discouraged due to human and environmental hazards. Therefore, the insecticidal effectiveness of aqueous leaf extract C. odorata against Macrotermes species was investigated. Five concentrations (0, 2.5, 5.0, 7.5 and 10.0% (w/v)) of the aqueous extract of C. odorata plant were evaluated for repellency and toxicity on the worker caste of Macrotermes species following standard procedures. The filter paper impregnation technique was used for the bioassay. Percentage repellency was monitored for 30 minutes and mortality recorded at 12, 24 and 36 hours post exposure. The leaf extract of C. odorata significantly repelled 95% of Macrotermes species at the highest concentration of 10% (w/v) after 30 minutes post treatment exposure. Mortality of Macrotermes species was independent of treatment concentration, but dependent on duration of exposure. All treatment concentrations of aqueous leaf extract of C. odorata caused significant mortality against Macrotermes species ranging between 94% and 98% compared to the control; indicating very great potential for adoption and use in the management of Macrotermes species.
