    Ageratum conyzoides L. is potential allelopathic weed very useful for its antifungal and antimicrobial activity. Being environmentally safe and friendly, it has the potential to substitute synthetic fungicides. The current study, therefore, was designed to evaluate the in vitro efficacy of aqueous methanolic and n-hexane extracts of A. conyzoides against the pathogenic fungi, Fusarium solani Mart. (Sacc.), isolated from roots of egg plant (Solanum melongena). The target fungus was exposed to various concentrations (2, 4 and 6% w/v) of   aqueous, methanolic and n-hexane extracts of Inflorescence, leaf, stem and root. All the employed    concentrations of extracts of four plant parts significantly suppressed the growth of the target fungal   pathogen.  The n-hexane extracts of leaf and inflorescence caused highly significant reduction of 84% in growth of F. solani followed by stem and root extracts which caused which caused 80% and 72% reduction in growth, respectively. The same pattern in growth reduction was observed in methanolic and aqueous extracts. Among the four parts of the tested weed, different concentrations of the methanolic extract of leaf were found to be  highly effective in controlling target fungal species resulting in up to 78% reduction in fungal biomass over  control followed by inflorescence (74% reduction), stem (63% reduction) and root (59% reduction) at highest used concentration. In case of aqueous extracts, the maximum reduction was observed in leaf extract (72%) followed by inflorescence, stem and root, respectively.Key words: Ageratum conyzoides, aqueous extract, Fusarium solani, n-hexane extract, methanolic extract

    The objective of this thesis is to develop a conceptual model that determines how employee perceptions of their work environments are related to their wellbeing and behaviour. This thesis replicates and extends job demands-control-support (JDCS) theory by integrating variables associated with perceived work environment characteristics (job demands, autonomy, managerial support, and family support), general wellbeing (anxiety), job-related wellbeing (job satisfaction and organization commitment), behaviour (turnover), personal characteristics (male versus female employees), and organizational characteristics (public versus private sectors) into a coherent model. The structural equation modelling technique is used to validate of the measurement model and for examining the inter-relationships among these variables at both the individual and workplace level. For the purpose of analysis, data has been taken from 2004 Workplace Employment Relations Survey (VVERS 2004). At individual level, the findings suggest that employee perceptions of their work environment are associated with their general and job-related wellbeing. The empirical findings show that (1) higher job demands placed on employees and perceived lack of family support influence job attitudes through their effect on anxiety, (2) high job control and managerial support reduces work related anxiety and increases job satisfaction and organization commitment, and (3) male and female employees do not perceive their work environments differently. At workplace level, the findings suggest that employee shared perceptions of their work environment are associated with their wellbeing and behaviour. The empirical findings show that: (1) higher job demands placed on employees increases their work related anxiety and reduces their job satisfaction in private workplaces, (2) high job control and managerial support increases job satisfaction and organization commitment, (3) perceived lack of family support reduces organization commitment in private sector, (4) job satisfaction is the only direct antecedent of turnover, (5) of work environment characteristics, autonomy and managerial support are indirect antecedents of turnover, (6) lack of family support reduces organization commitment in private sector. Overall, the thesis indicates that while JDCS theory is useful in explaining employees psychological and health related wellbeing, extending theory to include family support and using extended theory to predict job-related wellbeing and turnover increases our understanding of the underlying phenomena

    Recruitment Methods Used by Software Industry in Pakistan: Issues and Concerns

    Get PDF
    The research aims to examine the relationship between the organization size and the recruitment methods used. It also examines the differences in recruitment methods for filling the managerial and non managerial positions and exploring possible reasons for switching between these methods among IT organizations. We found that there is a significant relationship between the organization size and the frequency of recruitment. The smaller organizations tend to recruit more frequently as compared to larger organizations. The results also show that there is significant positive relationship between the size of organization and the choice of methods for recruitment of professionals. Most software houses find it difficult to recruit individuals with adequate professional training, skills and experience. Most professionals in the industry are fresh graduates with a sound theoretical base but with inadequate practical experience and skills. Software houses can help in developing these fresh graduates in more mature professionals by offering extensive internship programs

    The present study aims to: firstly, highlight the effectiveness of using literature in ELT classes in an interesting and innovative manner in Pakistan; secondly, to help language teachers develop a thoughtful and principled approach to using literature in the language classroom; thirdly, to provide teachers with the tools for developing their own classroom materials and for using these materials in a way that is relevant to their learners’ needs. This paper explores the text of ‘Good Bye Mr. Chips’, a famous novel by James Hilton (1934) for teaching at the Intermediate level. For the analysis of data, insights are taken from the works of Dubin & Olshtain (1977), Collie & Slater (1987) and Robinette. B. W (1978). It was found that activities like role plays and a lot of pair work and group work not only caused reduction in anxiety level of students but also increased their level of interest and enthusiasm. It also concluded that for facilitating language teaching and learning, the formation of a variety of activities based on learners’ needs from carefully and properly selected texts is unavoidable. Future researchers can exploit similar literary texts following the same frameworks for language teaching purposes.El presente estudio tiene como objetivo: en primer lugar, destacar la eficacia del uso de la literatura en las clases de ELT de una manera interesante e innovadora en Pakistán; en segundo lugar, ayudar a los profesores de idiomas a desarrollar un enfoque reflexivo y basado en principios para utilizar la literatura en el aula de idiomas; tercero, proporcionar a los maestros las herramientas para desarrollar sus propios materiales de clase y para usar estos materiales de una manera que sea relevante para las necesidades de sus alumnos.
