Performance evaluation of adaptive context aware rate selection algorithm (ACARS) for road safety applications in vehicular network

One of the major drawbacks for mobile nodes in wireless networks is power management. Our goal is to evaluate the performance power control scheme to be used to reduce network congestion, improve quality of service and collision avoidance in vehicular network and road safety application. Some of the importance of power control (PC) are improving spatial reuse, and increasing network capacity in mobile wireless communications. In this simulation we have evaluated the performance of existing rate algorithms compared with context Aware Rate selection algorithm (ACARS) and also seen the performance of ACARS and how it can be applied to road safety, improve network control and power management. Result shows that ACARS is able to minimize the total transmit power in the presence of propagation processes and mobility of vehicles, by adapting to the fast varying channels conditions with the Path loss exponent values that was used for that environment which is shown in the network simulation parameter. Our results have shown that ACARS is a very robust algorithm which performs very well with the effect of propagation processes that is prone to every transmitted signal in mobile networks. © 2013 IEEE.

Sustainability and supply chain management:Publications in Brazil

The number of research papers linking sustainability with supply chain management is increasing around the world. The purpose of this paper is to analyse how the publications in Brazil are considering the relationship between sustainability and supply chain management. The methodology applied consists in five major steps: (1) selection of databases and journals, (2) selection of the papers, (3) reading of papers' abstracts to select only papers that are related to business and sustainability, (4) qualitative and quantitative analysis of the selected papers' abstracts to define the main dimension of sustainability and sustainability aspect, and finally, (5) an evaluation of experts' responses to a questionnaire in the field of sustainability and supply chain in Brazil. The literature review was conducted in 120 Brazilian academic journals in which 124 papers were identified as being published in relation to sustainability, business management and companies, from 2008 until 2013. When considering the traditional Triple Bottom Line approach, the results of the analysis show that sustainability research in Brazil is focusing on the environmental dimension and SCM research is focusing on the economic dimension. Additional inputs are provided by integrating the governance dimension in the analysis to underline which actions and policies are discussed in Brazilian literature at a corporate level. The consultation of experts in the field of sustainability in Brazil was aimed at understanding better the results of the conducted literature review. One of the main conclusions is that there are large opportunities to increase publications about sustainability and SCM in the country.

GPs' perspectives on managing the NHS Health Check in primary care:a qualitative evaluation of implementation in one area of England

OBJECTIVES: To evaluate the implementation of the National Health Service (NHS) Health Check programme in one area of England from the perspective of general practitioners (GPs). DESIGN: A qualitative exploratory study was conducted with GPs and other healthcare professionals involved in delivering the NHS Health Check and with patients. This paper reports the experience of GPs and focuses on the management of the Heath Check programme in primary care. SETTING: Primary care surgeries in the Heart of Birmingham region (now under the auspices of the Birmingham Cross City Clinical Commissioning Group) were invited to take part in the larger scale evaluation. This study focuses on a subset of those surgeries whose GPs were willing to participate. PARTICIPANTS: 9 GPs from different practices volunteered. GPs served an ethnically diverse region with areas of socioeconomic deprivation. Ethnicities of participant GPs included South Asian, South Asian British, white, black British and Chinese. METHODS: Individual semistructured interviews were conducted with GPs face to face or via telephone. Thematic analysis was used to analyse verbatim transcripts. RESULTS: Themes were generated which represent GPs' experiences of managing the NHS Health Check: primary care as a commercial enterprise; 'buy in' to concordance in preventive healthcare; following protocol and support provision. These themes represent the key issues raised by GPs. They reveal variability in the implementation of NHS Health Checks. GPs also need support in allocating resources to the Health Check including training on how to conduct checks in a concordant (or collaborative) way. CONCLUSIONS: The variability observed in this small-scale evaluation corroborates existing findings suggesting a need for more standardisation. Further large-scale research is needed to determine how that could be achieved. Work needs to be done to further develop a concordant approach to lifestyle advice which involves tailored individual goal setting rather than a paternalistic advice-giving model.

The MG Rover closure and policy response: an evaluation of the Task Force model in the UK

In recent years there have been a number of high-profile plant closures in the UK. In several cases, the policy response has included setting up a task force to deal with the impacts of the closure. It can be hypothesised that task force involving multi-level working across territorial boundaries and tiers of government is crucial to devising a policy response tailored to people's needs and to ensuring success in dealing with the immediate impacts of a closure. This suggests that leadership, and vision, partnership working and community engagement, and delivery of high quality services are important. This paper looks at the case of the MG Rover closure in 2005, to examine the extent to which the policy response to the closure at the national, regional and local levels dealt effectively with the immediate impacts of the closure, and the lessons that can be learned from the experience. Such lessons are of particular relevance given the closure of the LDV van plant in Birmingham in 2009 and more broadly – such as in the case of the downsizing of the Opel operation in Europe following its takeover by Magna.

A cikkben a szerzők megvizsgálják a tudásmenedzsment komplex rendszerfejlesztési projektekben és az informatikai auditban játszott szerepét. Fő céljuk, hogy a tudásmenedzsment-rendszerek fejlesztéséhez kapcsolódó audit támogatására értékelési modellt készítsenek. Cikkükben megvizsgálják a tudásmenedzsmentnek az IT-auditban játszott általános szerepét, az auditban érintett tudásvagyon védelmének kérdését, a tudásmenedzsment-folyamatok szerepét a rendszerfejlesztésben (auditszempontból), a kontrollok implementálását, valamint a tudásmenedzsment és az IT-audittal kapcsolatos szabványok, módszertanok kapcsolatát. Az eredmények illusztrálására egy az Európai Unió 7. keretprogramjából finanszírozott nemzetközi projekt (GUIDE, IST–2003–507498) szolgál. ________________ Authors investigate the role of knowledge management in complex system development projects and IT audit. The primary goal is to provide an evaluation framework for an assessment of the development of special knowledge management solutions. On the other hand IT audit itself is a knowledge-dependent activity. The paper analyses the role of knowledge management in IT audit in general, the protection of knowledge assets during an audit, the role of knowledge management processes during system development (from audit point of view) and in the implementation of controls, the relationship of knowledge management with audit standards. Authors investigate the specialities of KM developments from audit point of view (particularly important aspects of audit, specific control objectives) A case study, based on experiences gained from GUIDE project (IST-2003-507498 funded by the European Commission’s 6th Framework Programme) illustrates the findings.

A környezeti teljesítményértékelés módszerei (Environmental performance evaluation methods)

A környezeti teljesítmény mérésére számtalan módszer létezik. A cikk a környezeti teljesítményértékelési eszközök útvesztőjében kínál némi eligazítást azáltal, hogy hat, a gyakorlatban is többé-kevésbé használt módszert mutat be és értékel. A szerző kísérletet tesz a bemutatott módszerek összehasonlítására is aszerint, hogy kitérnek-e a környezeti és a vállalati teljesítmény kapcsolatának vizsgálatára, illetve a környezeti teljesítményt kellően átfogóan vizsgálják-e. Nagyító alá kerül az a kérdés is, hogy vajon a teljesítményértékelési módszerek alapján jól teljesítő vállalatok valóban tekinthetők-e fenntarthatónak. ________ There are numerous methods existing for evaluating corporate environmental performance. The article offers some guidance in this labyrinth by introducing and evaluating six, in practice also used methods. The author makes an attempt to compare the different methods, whether they cover the relationship between environmental and company performance, and whether they analyse different components of environmental performance comprehensively enough. The question is also covered, whether companies with excellent performance based on the methods analysed can really be regarded as sustainable companies.

Mérés és értékelés a számvitelben (Measurement and evaluation in the accounting)

A cikk kiindulópontja az a tény, hogy a számvitel, azon belül is a pénzügyi beszámolás alapvető feladata döntésekhez hasznosítható információk nyújtása a vállalkozásokkal kapcsolatba kerülő érintettek számára. A gazdasági jelenségek leképezése, számviteli transzformációja során létrejövő adatok információként való hasznosításának feltétele, hogy a pénzügyi kimutatások felhasználói tisztában legyenek a leképezés mögöttes feltételezéseivel. A cikk első része a mérés általános definíciójából kiindulva mutatja be a számviteli mérés és értékelés fogalmát, ezek összefüggését, alapvető jellemzőit. Ezt követően a pénzügyi beszámolásban jelenleg érvényesülő értékelési keretrendszert vázolja fel a nemzetközi (IFRS), illetve a magyar szabályozásból kiindulva. A cikk harmadik része a szabályozás mögött meghúzódó elméleti összefüggéseket vizsgálja, kitérve a számviteli mérés és a pénzügyi teljesítmény (jövedelem) kapcsolatára, valamint bemutatja és értékeli a számviteli méréssel kapcsolatos főbb kritikákat. ____ One of the central problems of accounting theory and accounting regulation is accounting valuation, accounting as a value assignment aspect of the representation of economic phenomena. The first part of the article, setting out from the general concept of measurement, introduces the concepts of measurement and valuation as applied in accounting, describing their interconnections and basic characteristics. Following this, based on the international (IFRS) and Hungarian regulations, the paper sketches the current valuation framework used in financial reporting. The third part of the article analyses the theoretical background of the effective regulation, while also covering the connection of accounting measurement and financial performance (income), and finally it presents and evaluates the main elements of criticism concerning measurement in accounting.

US Screening and Evaluation System of Inventions Utilized in Hungary

The commercialization of inventions is very complex and challenging therefore it requires the collaboration of several actors in an economy. Even when an invention possesses significant added value, its successful commercialization could only be executed in a stable macroeconomic and innovation environment and also if proper innovation management expertise is provided. ValDeal Innovations Zrt. was established to foster the commercialization of Hungarian, high business potential inventions by providing its business expertise. The company used an – already in various markets and countries probed – US innovation management method consisting of the tasks of technology evaluation as well as the commercialization of inventions. There were major changes necessary while probing the US method residing in the different macroeconomic circumstances and the attitudes for innovation in Hungary. The article details the above mentioned issues together with the conclusions the members of ValDeal have drawn during the innovation management process.
