Working under a black cloud:how to sustain organizational identification after a merger

This article argues against the merger folklore that maintains that a merger negatively affects well-being and work attitudes primarily through the threat of job insecurity. We hold that the workplace is not only a resource for fulfilling a person's financial needs, but that it is an important component of the self-concept in terms of identification with the organization, as explained by social identity theory. We unravel the key concepts of the social identity approach relevant to the analysis of mergers and review evidence from previous studies. Then, we present a study conducted during a merger to substantiate our ideas about the effects of post-merger organizational identification above and beyond the effects of perceived job insecurity. We recommend that managers should account for these psychological effects through the provision of continuity and specific types of communication. © 2006 British Academy of Management.

The linguistic situation in Kirkuk:a sociolinguistic study

This study is concerned with the linguistic situation in the town of Kirkuk in north eastern Iraq. In this town there are three main ethnic groups: Kurds, Arabs and Turkmana with some very smell minorities such as Chaldeene, Assyrians and Armenians. The languages spoken by these three ethnic groups belong to different language Family groups. In the First cart of the study the historical background of the population, a review of the literature, both of the present linguistic situation in Kirkuk end of relevant sociolinguistics in general, and the theoretical Framework, have been discussed in detail in order to provide background to this study which is mainly concerned with the Following areas: 1. The relationships existing between ethnic background and language usage and language loyalty in Kirkuk. 2. The attitudes of Kirkukiane towards language maintenance and language shift in Kirkuk. 3. Bilingual, multilingual individual communicative competence of Kurds, Arabs and Turkmans in the languages concerned, including the degree to which such a speaker is bilingual or multilingual and the nature of bilingualism or multilingualism in different domains and situations in Kirkuk. To throw light a these areas a situationally-oriented language survey was conducted; the relevant data was collected by randomly distributed questionnaire, by parsonal interview, by personal observation of language use and language attitudes in this town. The data subjected to commuter analysis and the results proved that the were no significant and substantial correlations between the language use, attitudes and competence based on the socio-economic status of respondents in this town, on the other hand, the correlations between the ethnic backgrounds and the language, use, attitudes and competence are indisoutable.

Post-vernacular language use in a Low German linguistic community

In a time of rapid shift and loss of smaller, regional and minority languages it becomes apparent that many of them continue to play a role as post-vernacular varieties. As Shandler (2006) points out for Yiddish in the United States, some languages serve the purpose of identity-building within a community even after they have ceased to be used as a vernacular for daily communication. This occurs according to Shandler through a number of cultural practices, such as amateur theatre, music and folklore, translation, attempts to learn the language in evening classes, etc. This paper will demonstrate that the paradigm developed by Shandler for Yiddish can be applied to other linguistic communities, by comparing the post-vernacular use of Yiddish with Low German in Northern Germany. It will focus on the linguistic strategies that individuals or groups of speakers apply in order to participate in a post-vernacular language community.

Cytotoxic activity of Fagonia cretica against human breast cancer cells

In many parts of the world, plants are directly utilised for their medicinal properties. Traditional medicine from Pakistan, India and the Far East is well documented and its history is embedded in folklore. It has been documented that an aqueous extract of the desert shrub, Fagonia cretica, is a popular treatment for breast cancer in Pakistan. The administration of an aqueous extract of Fagonia cretica is reported effective at reducing tumour size and improving the quality of life of breast cancer patients, is well tolerated and does not exhibit adverse effects like vomiting, diarrhoea or alopecia which are common side effects of standard cytotoxic therapy. In the past, many pharmacologically active and chemotherapeutic compounds have been isolated from plants which subsequently have proven to be successful in clinical trials and been used as primary compounds in therapeutic regimes. Fagonia cretica has historical use as a treatment for breast cancer, yet there is little scientific evidence which shows chemotherapeutic potential towards breast tumours. Preparation and analysis of an aqueous extract of Fagonia cretica may reveal novel chemotherapeutic agents that can be used to effectively target cancer cells. An understanding of the mechanism of any activity may improve our understanding of cancer cell biology and reveal novel therapeutic targets. This thesis describes for the first time that an aqueous extract of Fagonia cretica shows potent in vitro cytotoxic activity towards breast cancer epithelial cell lines which was not seen towards normal mammary epithelial cells. Elucidation and characterisation of the cytotoxic mechanism was undertaken by analysing DNA damage, cell cycle status, apoptosis, metabolic state and expression of transcription factors and their targets. Finally, methods for the isolation and identification of active compound(s) were developed using various chromatographic techniques. An aqueous extract of Fagonia cretica was able to reduce cell viability significantly in two phenotypically different breast cancer cell lines (MCF-7 and MDA-MB-231). This activity was markedly reduced in normal mammary epithelial cells (HMEpC). Further investigation into the mode of action revealed that extract treatment induced cell cycle arrest and apoptosis in both MCF-7 and MDA-MB-231 cell lines. This coincided with the formation of DNA double stranded breaks and the DNA repair marker ?-H2AX. In MCF-7 cells, ATM/ATR activation resulted in increased p53 expression and of its transcriptional targets p21 and bax, suggesting a role for a p53-mediated response. Furthermore, inhibition of extract-induced p53 expression with siRNA reduced the cytotoxic effect against MCF-7 cells. Extract treatment was also associated with increased FOXO3a expression in MCF-7 and MDA-MB-231 cells. In the absence of functional p53, siRNA knockdown of extract-induced FOXO3a expression was completely abrogated, suggesting that FOXO3a plays a vital role in extract-induced cytotoxicity. Isolation and characterisation of the active compound(s) within the extract was attempted using liquid chromatography and mass spectrometry in conjunction with a cell viability assay. Multiple fractionations generated an active fraction that contained four major compounds as detected by mass spectrometry. However, none of these compounds were identified structurally or chemically due to constraints within the methodology.
