    In his study activated carbon was prepared from Helhelok stones as a raw material by using chemical activation with zinc chloride (ZnCl2) as a chemical agent with the concentration 40% for 25h at (25⁰C±2). The optimum conditions were approved in having carbonization temperature 400ᵒC for 1h to get a maximum percentage of yield 56%. Other properties of the prepared activated carbon were also studied such as pH, ash content, density, moisture content, conductivity, iodine number and methylene blue dye absorbance. Eventually the prepared activated carbon in this work has obtained good characteristics that make it play an essential role in industrial uses and compared it with commercial standard sample from B.

    What are the consequences of a managerial approach to union renewal for union behaviour? A case study of USDAW

    Get PDF
    Purpose: This paper explores the consequences of a managerialist approach to renewal for a union’s behaviour by analysing the UK’s fourth largest trade union - The Union of Shop, Distributive and Allied Workers (USDAW). Design/methodology/approach: The findings draw on in-depth semi-structured interviews with union officials. Findings: The research findings show the significance of a managerialist approach to UDSAW’s renewal strategy and its correlation with existing renewal strategies of organising and partnership. However, this was not immune to context with tensions between agency and articulation challenging the basic concept of managerialism and influencing union behaviour. Research limitations/implications: The data were collected from a single case with a small sample size. Practical implications: Unions could benefit from a managerialist approach to insure against external challenges, but tensions between democracy and efficiency will mediate any such approach to union renewal. Originality/value: This paper brings together the current disparate themes in the literature to propose a conceptual framework of three key elements of managerialism: leadership or centralised renewal strategies; performance management techniques; and the managerialisation of union roles. To date, these elements of managerialism have not been studied simultaneously in a research project and without such knowledge, we lack a comprehensive understanding of the true complexities of how unions organise and renew, both conceptually and empirically. Consequently, we argue that theories of union renewal need to better reflect the complexities of a hybrid approach that unions, such as USDAW, are adopting, particularly their achievements of internal leveraging

    Union effectiveness: In Search of the Holy Grail

    Get PDF
    YesThis article revisits the concept of union effectiveness and proposes a conceptual model to inform its study and application. Previous conceptual and empirical work is examined to identify key strengths and weaknesses, and to relate the union effectiveness concept to union renewal and other key concepts. This leads to the proposal of a Goal-System framework that builds and improves on prior research

    Anti-corruption Strategies in Afghanistan: An Alternative Approach

    Get PDF
    © 2016, © 2016 SAGE Publications. Afghanistan is one of the most corrupt countries in the world. This article provides a critical examination of Afghan anticorruption strategies based on formal anticorruption strategy, bureaucratic reform, and counter-narcotics. This article includes reference to some of the opinions of 70 semi-structured interviews conducted by the author in Kabul during May–June 2010 with anticorruption experts, rights-based organizations, civil society groups, ministries, and international and national organizations. The findings are that political interference from Afghan elites preserves corruption and deep roots of patron–client corruption—patronage networks and illicit drug trafficking interests with criminal groups for profitable gain—are difficult to combat with the existing anticorruption strategy. Hence, new approaches need to be attempted, such as, incorporating religion and ethics and empowering local leaders to combat corruption within a sixfold approach which involves (i) raising awareness, (ii) prevention, (iii) prosecution and sanctions, (iv) detection, (v) a collaborative counter-narcotics strategy, and (vi) linking religion

    Divergent mind-sets, convergent policies: Policing models against organized crime in Italy and in England within international frameworks

    Get PDF
    The fight against organized crime is a very fertile ground for policymaking at various levels. On one side, because of the perceived transnationality of the phenomenon, national states are inclined to develop harmonized responses within the European or international law frameworks. On the other side, national conceptualizations and manifestations of organized crime often make these harmonizations quite challenging. This paper shares the findings of a socio-legal investigation carried out in England and in Italy through interviews and document analysis, comparing the two national models against organized crime. The paper presents these two models ? the Italian Structure Model and the English Activity Model, which are very different in many ways ? in order to identify divergences and convergences of policies and practices. This comparative exercise not only improves our understanding of national approaches, beyond cultural, linguistic and legal boundaries, but also improves the dialogue towards concerted efforts at the international level. Nevertheless, the globalization of criminal markets and the internationalization of policies have influenced perceptions of organized crime and related policing tactics at national levels too. This paper will briefly look at international perspectives to assess to what extent divergent and convergent areas between the two models are also areas of interest and focus at the international level, in order to conclude with an enhanced understanding of both models before drawing conclusions

    Voices unheard : employee voice in the new century

    Get PDF
    The concept of employee voice has attracted considerable attention in research since the 1980s primarily in the fields of Employment Relations/Human Resource Management (ER/HRM) and Organisational Behaviour (OB). Each of these disciplines focuses on different aspects of employee voice, the former examining the mechanisms for employees to have \u27a say\u27 in organisational decision-making (Freeman, Boxall, & Haynes, 2007; Gollan, Kaufman, Taras, & Wilkinson, 2015; Wilkinson & Fay, 2011) and the latter considering voice as an \u27extra-role upward communication behaviour\u27 (Morrison, 2014, p. 174) with the intent to improve organizational functioning. The purpose of voice is seen by each of these disciplines in a different way. ER/HRM perspectives are underpinned by the assumption that it is a fundamental democratic right for workers to extend a degree of control over managerial decision-making within an organisation (Kaufman, 2015; Wilkinson, Gollan, Lewin, & Marchington, 2010). Thus, everyone should have a voice and a lack of opportunities to express that voice may adversely affect workers\u27 dignity. In contrast, OB perspectives are underpinned more by a concern with organisational improvements, therefore leaving it much more to managerial discretion to reduce or change existing voice arrangements due to, for example, an economic downturn (Barry & Wilkinson, 2016)

    Common variation on 14q24.1, close to RAD51B, has been associated with breast cancer: rs999737 and rs2588809 with the risk of female breast cancer and rs1314913 with the risk of male breast cancer. The aim of this study was to investigate the role of RAD51B variants in breast cancer predisposition, particularly in the context of familial breast cancer in Finland. We sequenced the coding region of RAD51B in 168 Finnish breast cancer patients from the Helsinki region for identification of possible recurrent founder mutations. In addition, we studied the known rs999737, rs2588809, and rs1314913 SNPs and RAD51B haplotypes in 44,791 breast cancer cases and 43,583 controls from 40 studies participating in the Breast Cancer Association Consortium (BCAC) that were genotyped on a custom chip (iCOGS). We identified one putatively pathogenic missense mutation c.541C>T among the Finnish cancer patients and subsequently genotyped the mutation in additional breast cancer cases (n = 5259) and population controls (n = 3586) from Finland and Belarus. No significant association with breast cancer risk was seen in the meta-analysis of the Finnish datasets or in the large BCAC dataset. The association with previously identified risk variants rs999737, rs2588809, and rs1314913 was replicated among all breast cancer cases and also among familial cases in the BCAC dataset. The most significant association was observed for the haplotype carrying the risk-alleles of all the three SNPs both among all cases (odds ratio (OR): 1.15, 95% confidence interval (CI): 1.11–1.19, P = 8.88 x 10−16) and among familial cases (OR: 1.24, 95% CI: 1.16–1.32, P = 6.19 x 10−11), compared to the haplotype with the respective protective alleles. Our results suggest that loss-of-function mutations in RAD51B are rare, but common variation at the RAD51B region is significantly associated with familial breast cancer risk

    Adjuvant chemoradiotherapy versus radiotherapy alone in women with high-risk endometrial cancer (PORTEC-3): patterns of recurrence and post-hoc survival analysis of a randomised phase 3 trial

    Get PDF
    Background: The PORTEC-3 trial investigated the benefit of combined adjuvant chemotherapy and radiotherapy versus pelvic radiotherapy alone for women with high-risk endometrial cancer. We updated the analysis to investigate patterns of recurrence and did a post-hoc survival analysis. // Methods: In the multicentre randomised phase 3 PORTEC-3 trial, women with high-risk endometrial cancer were eligible if they had International Federation of Gynaecology and Obstetrics (FIGO) 2009 stage I, endometrioid grade 3 cancer with deep myometrial invasion or lymphovascular space invasion, or both; stage II or III disease; or stage I–III disease with serous or clear cell histology; were aged 18 years and older; and had a WHO performance status of 0–2. Participants were randomly assigned (1:1) to receive radiotherapy alone (48·6 Gy in 1·8 Gy fractions given on 5 days per week) or chemoradiotherapy (two cycles of cisplatin 50 mg/m2 given intravenously during radiotherapy, followed by four cycles of carboplatin AUC5 and paclitaxel 175 mg/m2 given intravenously), by use of a biased coin minimisation procedure with stratification for participating centre, lymphadenectomy, stage, and histological type. The co-primary endpoints were overall survival and failure-free survival. Secondary endpoints of vaginal, pelvic, and distant recurrence were analysed according to the first site of recurrence. Survival endpoints were analysed by intention-to-treat, and adjusted for stratification factors. Competing risk methods were used for failure-free survival and recurrence. We did a post-hoc analysis to analyse patterns of recurrence with 1 additional year of follow-up. The study was closed on Dec 20, 2013; follow-up is ongoing. This study is registered with ISRCTN, number ISRCTN14387080, and ClinicalTrials.gov, number NCT00411138. // Findings: Between Nov 23, 2006, and Dec 20, 2013, 686 women were enrolled, of whom 660 were eligible and evaluable (330 in the chemoradiotherapy group, and 330 in the radiotherapy-alone group). At a median follow-up of 72·6 months (IQR 59·9–85·6), 5-year overall survival was 81·4% (95% CI 77·2–85·8) with chemoradiotherapy versus 76·1% (71·6–80·9) with radiotherapy alone (adjusted hazard ratio [HR] 0·70 [95% CI 0·51–0·97], p=0·034), and 5-year failure-free survival was 76·5% (95% CI 71·5–80·7) versus 69·1% (63·8–73·8; HR 0·70 [0·52–0·94], p=0·016). Distant metastases were the first site of recurrence in most patients with a relapse, occurring in 78 of 330 women (5-year probability 21·4%; 95% CI 17·3–26·3) in the chemoradiotherapy group versus 98 of 330 (5-year probability 29·1%; 24·4–34·3) in the radiotherapy-alone group (HR 0·74 [95% CI 0·55–0·99]; p=0·047). Isolated vaginal recurrence was the first site of recurrence in one patient (0·3%; 95% CI 0·0–2·1) in both groups (HR 0·99 [95% CI 0·06–15·90]; p=0·99), and isolated pelvic recurrence was the first site of recurrence in three women (0·9% [95% CI 0·3–2·8]) in the chemoradiotherapy group versus four (0·9% [95% CI 0·3–2·8]) in the radiotherapy-alone group (HR 0·75 [95% CI 0·17–3·33]; p=0·71). At 5 years, only one grade 4 adverse event (ileus or obstruction) was reported (in the chemoradiotherapy group). At 5 years, reported grade 3 adverse events did not differ significantly between the two groups, occurring in 16 (8%) of 201 women in the chemoradiotherapy group versus ten (5%) of 187 in the radiotherapy-alone group (p=0·24). The most common grade 3 adverse event was hypertension (in four [2%] women in both groups). At 5 years, grade 2 or worse adverse events were reported in 76 (38%) of 201 women in the chemoradiotherapy group versus 43 (23%) of 187 in the radiotherapy-alone group (p=0·002). Sensory neuropathy persisted more often after chemoradiotherapy than after radiotherapy alone, with 5-year rates of grade 2 or worse neuropathy of 6% (13 of 201 women) versus 0% (0 of 187). No treatment-related deaths were reported. // Interpretation: This updated analysis shows significantly improved overall survival and failure-free survival with chemoradiotherapy versus radiotherapy alone. This treatment schedule should be discussed and recommended, especially for women with stage III or serous cancers, or both, as part of shared decision making between doctors and patients. Follow-up is ongoing to evaluate long-term survival
