Molecular basis for the exquisite sensitivity of Mycobacterium tuberculosis to isoniazid

The exceptional sensitivity of Mycobacterium tuberculosis to isonicotinic acid hydrazide (INH) lacks satisfactory definition. M. tuberculosis is a natural mutant in oxyR, a central regulator of peroxide stress response. The ahpC gene, which encodes a critical subunit of alkyl hydroperoxide reductase, is one of the targets usually controlled by oxyR in bacteria. Unlike in mycobacterial species less susceptible to INH, the expression of ahpC was below detection limits at the protein level in INH-sensitive M. tuberculosis and Mycobacterium bovis strains. In contrast, AhpC was detected in several series of isogenic INH-resistant (INHr) derivatives. In a demonstration of the critical role of ahpC in sensitivity to INH, insertional inactivation of ahpC on the chromosome of Mycobacterium smegmatis, a species naturally insensitive to INH, dramatically increased its susceptibility to this compound. These findings suggest that AhpC counteracts the action of INH and that the levels of its expression may govern the intrinsic susceptibility of mycobacteria to this front-line antituberculosis drug.

The Healthy Workplace of the 21st Century: The Benefit of Organizational Wellness Programs on Employee Health and Absenteeism

Every year, obesity rates continue to rise and have reached epidemic proportions throughout the United States. The costs associated with obesity are staggering and many researchers feel that the workplace should be the new front line in the battle for a healthier workforce. Employers must take action to address this worsening health crisis and help reduce spiraling medical costs and absenteeism rates. This capstone reviews the current literature on wellness programs and discusses different companies' approaches to wellness programs that have special emphasis on nutrition and physical activity. It also provides strategies and recommendations for companies eager to initiate a comprehensive, dynamic and directed wellness program to improve the current and future health of their workforce.

New Approaches, Alternative Avenues and Means of Access to Asylum Procedures for Persons Seeking International Protection. CEPS Liberty and Security in Europe No. 77/ January 2015

This study examines the workings of the Common European Asylum System (CEAS), in order to assess the need and potential for new approaches to ensure access to protection for people seeking it in the EU, including joint processing and distribution of asylum seekers. Rather than advocating the addition of further complexity and coercion to the CEAS, the study proposes a focus on front-line reception and streamlined refugee status determination, in order to mitigate the asylum challenges facing Member States, and vindicate the rights of asylum seekers and refugees according to the EU acquis and international legal standards. Joint processing could contribute to front-line reception and processing capacity, but is no substitute for proper investment in national systems. The Dublin system as currently configured leads inexorably to increasing coercion and detention, and must thus be reconfigured to remove coercion as a principle and ensure consistency with human rights and other fundamental values of the EU.

Still together, but apart? Kyiv’s policy towards the Donbas. OSW Commentary No. 160, February 6 2015

From the Introduction. The peace deal agreed on 5 September 2014 concerning the ceasefire in the region covered by the conflict in the Donbas brought about a significant reduction in the scale of military clashes. However, in mid-January the separatist forces, supported by the Russian military, started an offensive along the entire front line. For example, they seized the airport in Donetsk and the village of Krasnyi Partyzan. About a third of the Donetsk and the Lugansk oblasts currently remain outside Kyiv’s control (see Map). Before the war, these areas were inhabited by 6.6 million residents, 15% of Ukraine’s total population. The process launched in September 2014 in Minsk, which was intended to regulate the conflict within the so-called trilateral contact group (Ukraine, Russia, the OSCE and representatives of the separatists), resulted in an exchange of some prisoners of war, although it failed to have any political effects. Attempts at regulating the political situation were additionally complicated by the illegal ‘elections’ of leaders of the two separatist regions, the so-called Donetsk and Lugansk People’s Republics (the DPR and LPR).

Alternatives to conventional vaccines - Mediators of innate immunity

Vaccines have been described as weapons of mass protection. The eradication of many diseases is testament to their utility and effectiveness. Nevertheless, many vaccine preventable diseases remain prevalent because of political and economic barriers. Additionally, the effects of immaturity and old age, therapies that incapacitate the adaptive immune system and the multitude of strategies evolved by pathogens to evade immediate or sustained recognition by the mammalian immune system are barriers to the effectiveness of existing vaccines or development of new vaccines. In the front line of defence against the pervasiness of infection are the elements of the innate immune system. Innate immunity is under studied and poorly appreciated. However, in the first days after entry of a pathogen into the body, our entire protective response is dependant upon the various elements of our innate immune repertoire. In spite of, its place as our initial defence against infection, attention is only now turning to strategies which enhance or supplement innate immunity. This review examines the need for and potential of innate immune therapies.

Managerialism and Public Housing Reform

This paper discusses market inspired changes to the delivery of public housing in Queensland, Australia during the late 1990s. These policy changes were implemented in an organisational environment dominated by managerialism. The theory and method of critical discourse analysis is used to examine how managerial subject positions were assimilated and/or creatively resisted by different actors within the public housing policy community. These themes are discussed using interview data with a range of policy actors, including policy managers, front-line housing staff and public housing tenants. The analysis suggests that policy actors who openly challenged the emerging policy and organisational direction were marginalised in changing power relations.

Room to move? Professional discretion at the frontline of welfare-to-work

Outcomes of social policies have always been mediated by the discretionary agency of front-line staff, processes which nevertheless have received insufficient attention in policy evaluation and in the social policy literature more broadly. This article takes the case example or the policy reforms associated with the Australian government's welfare-to-work agenda. Drawing on two discreet research projects undertaken at different points in the policy trajectory, the practices of social workers in Centrelink - the Commonwealth government's primary service delivery agency involved in welfare-to-work - is examined. Centrelink social workers have been and remain one of the core groups of specialist staff since the Department's inception in the late 1940s, working to improve the well being Of people in receipt of income security. Their experiences of the recent past and their expectations of the future of their professional practice as welfare reform becomes more entrenched are canvassed. In summary, the discretionary capacity of the Centrelink social workers to moderate or shape the impact of policy on income security recipients is steadily eroding as this group of professionals is increasingly captured by the emerging practices of workfare.

A INFLUÊNCIA DAS COMPETÊNCIAS COLETIVAS SOBRE A EFICÁCIA DO ATENDIMENTO AO CLIENTE

O relacionamento de longo prazo é atualmente o elemento-chave para o sucesso das organizações. Com um mercado tão competitivo, as empresas estão desenvolvendo estratégias que melhor possam satisfazer e criar valor para seus clientes. As empresas precisam definir muito bem as suas estratégias com foco na percepção de seus clientes e do mercado. Porém a criação de valor não advém apenas da qualidade de um produto, da tecnologia e da infraestrutura. Ela também tem base em valores intrínsecos como, por exemplo, as competências. Sendo assim, as empresas precisam investir nos profissionais de linha de frente para que eles desenvolvam competências e atendam às necessidades e desejos dos clientes. Este trabalho tem o intuito de demonstrar se as competências coletivas, desenvolvidas a partir da interação social de um grupo podem trazer algum(s) benefício(s) ou não para o atendimento ao cliente em termos de satisfação e criação de valor, promovendo o marketing de relacionamento. Em seu desenvolvimento, foram utilizadas como base as teorias de competência, competências coletivas, gestão do conhecimento, satisfação e criação de valor para o cliente e marketing de relacionamento. Porém, não foi possível encontrar na literatura qualquer relação entre os temas competências coletivas e marketing de relacionamento. Neste contexto, o presente trabalho teve como objetivo geral analisar como o desenvolvimento das competências coletivas de uma equipe de vendas pode influenciar a satisfação do cliente. Especificamente buscou-se a) levantar quais os principais fatores ligados à equipe de vendas que geram satisfação nos clientes; b) analisar como as competências coletivas da equipe de vendas influenciam a satisfação do cliente; c) identificar como se formam competências coletivas em uma equipe de vendas. A partir destes objetivos, o procedimento metodológico de abordagem qualitativa foi orientado pelo método de estudo de caso, com procedimentos de análise de dados de entrevistas, observação direta e levantamento de registros. Foram entrevistadas duas equipes de vendas de uma empresa multinacional no segmento de serviços para análise e proteção de crédito, envolvendo o gerente, três vendedores e um cliente de cada equipe, atendidos por estes vendedores. As observações foram realizadas em duas reuniões de vendas envolvendo vendedores e clientes, e os registros analisados referem-se a metas e número de clientes atendidos no mês. Os resultados evidenciam que as competências coletivas podem influenciar na satisfação do cliente, embora estes só percebam as competências individuais e organizacionais. Mas ficou evidente, por parte de vendedores e gerentes de equipe, que as competências coletivas, além de promover a satisfação do cliente, auxiliam no desenvolvimento e na formação de competências individuais das pessoas na área comercial.

A model of service performance enhancement:the role of transactional and transformational leadership

This paper is concerned with the ways in which transactional and transformational leadership styles can improve the service performance of front-line staff. Past literature on services marketing has indicated the importance of leadership but has largely ignored the parallel literature in which leadership styles have been conceptualized and operationalized (e.g., sales management, organizational psychology). This paper seeks to build upon existing services marketing theory by introducing the role of leadership styles in enhancing service performance. Consequently, a conceptual framework of the effect of transactional and transformational leadership styles on service performance, anchored in a crossdisciplinary literature review, is developed. Managerial implications and future research directions are also discussed.

Do many hands make light work? How to overcome social loafing and gain motivation in work teams

Purpose – The purpose of this paper is to challenge the assumption that process losses of individuals working in teams are unavoidable. The paper aims to challenge this assumption on the basis of social identity theory and recent research. Design/methodology/approach – The approach adopted in this paper is to review the mainstream literature providing strong evidence for motivation problems of individuals working in groups. Based on more recent literature, innovative ways to overcome these problems are discussed. Findings – A social identity-based analysis and recent findings summarized in this paper show that social loafing can be overcome and that even motivation gains in group work can be expected when groups are important for the individual group members' self-concepts. Practical implications – The paper provides human resource professionals and front-line managers with suggestions as to how individual motivation and performance might be increased when working in teams. Originality/value – The paper contributes to the literature by challenging the existing approach to reducing social loafing, i.e. individualizing workers as much as possible, and proposes a team-based approach instead to overcome motivation problems.

Local-authority led economic regeneration strategies in the aftermath of the Foot-and-Mouth Disease crisis of 2001

The Foot-and-Mouth Disease (FMD) outbreak of 2001 in the UK was completely unprecedented in its scale and severity, with over four million animals culled and a cost to the Exchequer of over £4 billion. Local authorities were at the front line in dealing with the outbreak, in coordinating the cull of livestock, the disposal of carcasses as well as attempting to deal with its aftermath and, in particular, the impact on the wider rural economy. This article examines the impacts of this crisis on three local authorities, Devon, Herefordshire and Cumbria. It examines how far the crisis acted as a catalyst in developing strategies to deal with a future outbreak as well as new local initiatives to promote regeneration in the areas most adversely affected. It focuses on developments that can be directly attributed to the crisis and shows that FMD had a considerable impact on communications and 'joined-up' activity within local authorities and with local stakeholders. © 2006, LEPU, South Bank University.

Antecedents of strategic flexibility:management cognition, firm resources and strategic options

Purpose: Current conceptualisations of strategic flexibility and its antecedents are theory-driven, which has resulted in a lack of consensus. To summarise this domain the paper aims to develop and present an a priori conceptual model of the antecedents and outcomes of strategic flexibility. Discussion and insights into the conceptual model, and the relationships specified, are made through a novel qualitative empirical approach. The implications for further research and a framework for further theoretical development are presented. Design/methodology/approach: An exploratory qualitative research design is used applying multiple data collection techniques in a branch network of a large regional retailer in the UK. The development of strategic options and the complex relationship to strategic flexibility is investigated. Findings: The number and type of strategic options developed by managers impact on the degree of strategic flexibility and also on the ability of the firm to achieve competitive differentiation. Additionally, the type of strategic option implemented by managers is dependent on the competitive situation faced at a local level. Evidence of managers' limited perception of competition was identified based on their spatial embeddedness. Research limitations/implications: A single, in-depth case study was used. The data gathered is rich and appropriate for the exploratory approach adopted here. However, generalisability of the findings is limited. Practical implications: Strategic flexibility is rooted in the ability of front-line mangers to develop and implement strategic options; this in turn facilitates competitive differentiation. Originality/value: The research presented is unique in this domain on two accounts. First, theory is developed by presenting an a priori conceptual model, and testing through in-depth qualitative data gathering. Second, insights into strategic flexibility are presented through an examination of managerial cognition, resources and strategic option generation using cognitive mapping and laddering technique. © Emerald Group Publishing Limited.
