Reactor design and its impact on performance and products

This chapter discusses engineering design and performance of various types of biomass transformation reactors. These reactors vary in their operating principle depending on the processing capacity and the nature of the desired end product, that is, gas, chemicals or liquid bio-oil. Mass balance around a thermal conversion reactor is usually carried out to identify the degree of conversion and obtain the amount of the various components in the product. The energy balance around the reactors is essential for determining the optimum reactor temperature and the amount of heat required to complete the overall reactions. Experimental and pilot-plant testing is essential for proper reactor design. However, it is common practice to use correlation and valid parameter values in determining the realistic reactor dimensions and configurations. Despite the recent progress in thermochemical conversion technology, reactor performance and scale up potential are the subjects of continuing research.

Content vs. process in the HRM-performance relationship:an empirical examination

This study investigates the impact of a human resource management (HRM) system, which integrates both content and process of human resource (HR) practices, on organizational performance, through collective employee reactions. The analysis is based on a sample of 1,250 Greek employees working in 133 public- and private-sector organizations, which operate in the present context of severe financial and economic crises. The findings of the structural equation modeling suggest that content and process are two inseparable faces of an HRM system that help to reveal a comprehensive picture of the HRM-organizational performance relationship. Based on the findings that collective employee reactions mediate the HRM content (i.e., organizational performance relationship) and HRM process moderates the HRM content (i.e., employee reactions relationship), the study has several theoretical and practice implications. © 2014 Wiley Periodicals, Inc.

The effectiveness of workplace coaching:a meta-analysis of learning and performance outcomes from coaching

This study presents a meta-analysis synthesizing the existing research on the effectiveness of workplace coaching. We exclusively explore workplace coaching provided by internal or external coaches and therefore exclude cases of manager-subordinate and peer coaching. We propose a framework of potential outcomes from coaching in organizations, which we examine meta-analytically (k = 17). Our analyses indicated that coaching had positive effects on organizational outcomes overall (δ = 0.36), and on specific forms of outcome criteria (skill-based δ = 0.28; affective δ = 0.51; individual-level results δ = 1.24). We also examined moderation by a number of coaching practice factors (use of multisource feedback; type of coach; coaching format; longevity of coaching). Our analyses of practice moderators indicated a significant moderation of effect size for type of coach (with effects being stronger for internal coaches compared to external coaches) and use of multisource feedback (with the use of multisource feedback resulting in smaller positive effects). We found no moderation of effect size by coaching format (comparing face-to-face, with blended face-to-face and e-coaching) or duration of coaching (number of sessions or longevity of intervention). The effect sizes give support to the potential utility of coaching in organizations. Implications for coaching research and practice are discussed.

From art for arts sake to art as means of knowing:a rationale for advancing arts-based methods in research, practice and pedagogy

This paper advances a philosophically informed rationale for the broader, reflexive and practical application of arts-based methods to benefit research, practice and pedagogy. It addresses the complexity and diversity of learning and knowing, foregrounding a cohabitative position and recognition of a plurality of research approaches, tailored and responsive to context. Appreciation of art and aesthetic experience is situated in the everyday, underpinned by multi-layered exemplars of pragmatic visual-arts narrative inquiry undertaken in the third, creative and communications sectors. Discussion considers semi-guided use of arts-based methods as a conduit for topic engagement, reflection and intersubjective agreement; alongside observation and interpretation of organically employed approaches used by participants within daily norms. Techniques span handcrafted (drawing), digital (photography), hybrid (cartooning), performance dimensions (improvised installations) and music (metaphor and structure). The process of creation, the artefact/outcome produced and experiences of consummation are all significant, with specific reflexivity impacts. Exploring methodology and epistemology, both the "doing" and its interpretation are explicated to inform method selection, replication, utility, evaluation and development of cross-media skills literacy. Approaches are found engaging, accessible and empowering, with nuanced capabilities to alter relationships with phenomena, experiences and people. By building a discursive space that reduces barriers; emancipation, interaction, polyphony, letting-go and the progressive unfolding of thoughts are supported, benefiting ways of knowing, narrative (re)construction, sensory perception and capacities to act. This can also present underexplored researcher risks in respect to emotion work, self-disclosure, identity and agenda. The paper therefore elucidates complex, intricate relationships between form and content, the represented and the representation or performance, researcher and participant, and the self and other. This benefits understanding of phenomena including personal experience, sensitive issues, empowerment, identity, transition and liminality. Observations are relevant to qualitative and mixed methods researchers and a multidisciplinary audience, with explicit identification of challenges, opportunities and implications.

New genre of antioxidants from renewable natural resources:synthesis and characterisation of rosemary plant-derived antioxidants and their performance in polyolefins

Several ester derivatives of rosmarinic acid (rosmarinates) were synthesised, characterised (1D and 2D NMR, UV and FTIR spectroscopy) and tested for their potential use as antioxidants derived from a renewable natural resource. The intrinsic free radical scavenging activity of the rosmarinates was assessed, initially using a modified DPPH (2, 2-diphenyl-1-picrylhydrazyl radical) method, and found to be higher than that of commercial synthetic hindered phenol antioxidants Irganox 1076 and Irganox 1010. The thermal stabilising performance of the rosmarinates in polyethylene (PE) and polypropylene (PP) was subsequently examined and compared to that of samples prepared similarly but in the presence of Irganox 1076 (in PE) and Irganox 1010 (in PP) which are typically used for polyolefin stabilisation in industrial practice. The melt stability and the long-term thermo-oxidative stability (LTTS) of processed polymers containing the antioxidants were assessed by measuring the melt flow index (MFI), melt viscosity, oxidation induction time (OIT) and long-term (accelerated) thermal ageing performance. The results show that both the melt and the thermo-oxidative stabilisation afforded by the rosmarinates, and in particular the stearyl derivative, in both PE and PP, are superior to those of Irganox 1076 and Irganox 1010, hence their potential as effective sustainable bio-based antioxidants for polymers. The rosmarinic acid used for the synthesis of the rosmarinates esters in this study was obtained from commercial rosemary extracts (AquaROX80). Furthermore, a large number of different strains of UK-grown rosemary plants (Rosmarinum officinalis) were also extracted and analysed in order to examine their antioxidant content. It was found that the carnosic and the rosmarinic acids, and to a much lesser extent the carnosol, constituted the main antioxidant components of the UK-plants, with the two acids being present at a ratio of 3:1, respectively.

Logisztikai folyamatok informatikai támogatottsága Magyarországon – fókuszban a disztribúciós logisztika = Backing logistics processes with information technology – current practice and improvement possibilities at Hungarian companies

Az elemzés egy, a Budapesti Corvinus Egyetem (BCE) Logisztika és Ellátási Lánc Menedzsment Tanszéke által végzett kérdőíves felmérés eredményeit foglalja össze. A kutatás alapvető célja, hogy felmérje és bemutassa a hazai vállalatok logisztikai, ezen belül is elsősorban disztribúciós logisztikai folyamatainak informatikai oldalról történő jelenlegi támogatottsági szintjét és a következő két-három év e téren várható fejlesztési irányait. A kutatás szisztematikusan kitért a logisztikai információs rendszer valamennyi alrendszerére, vizsgálta a különböző azonosítási megoldások elterjedtségét, a vállalatirányítási rendszer, illetve egyes moduljainak használatával kapcsolatban kialakult gyakorlatot, de a logisztika stratégiai döntéseinek informatikai támogatottságát és a használt kommunikációs technikákat is. Összességében megállapíthatjuk, hogy a logisztikai információs rendszerek fejlettségi szintje ma Magyarországon közepesnek mondható, fontos megjegyezni azonban, hogy a KKV szektor e téren is jelentős lemaradással rendelkezik. Ez természetesen azt is jelent, hogy az informatikai eszközök alkalmazásának kiterjesztésével még jelentős teljesítményjavulás érhető el. = The essay summarizes the results of a survey carried out by Corvinus University of Budapest, Department of Logistics and Supply Chain Management. Aim of the survey was to analyze and describe the actual Hungarian company practice regarding the IT support of logistics – and particularly distribution – processes, and the plans of developing it within the next 2-3 years. Survey has systematically covered all fields of logistics information system, analyzed the prevalence of different identification techniques and systems. On the whole we appoint that logistics information systems applied by Hungarian companies are on satisfactory level; however it is important to tell that SME companies are in huge lag. This means that improving logistics information system hides the possibility of considerable performance development.

Üzleti kapcsolatok – vállalati szemléletmód és gyakorlat = Business relationships - approach and practice in Hungary

A tanulmányunk fókuszában a vállalatközi kapcsolatok állnak. Az üzleti kapcsolatok, s ezek eredményes és hatékony menedzselése fontos értékteremtő tényező lehet. Az üzleti vállalkozások sikerét saját teljesítményük mellett üzleti partnereik (beszállítóik, alvállalkozóik, közvetítőik, megrendelőik, vevőik) teljesítménye, s a velük való kapcsolat eredményessége és hatékonysága egyaránt befolyásolja. Kutatásunkban a Versenyképesség-kutatás 2009. évi felmérésének eredményei alapján vizsgáltuk a vállalatközi kapcsolatok jellemzőit, lehetőség szerint összevetve a tapasztalatokat a korábbi hasonló felmérések (leginkább a 2004. évi, esetenként az 1996. és 1999. évi) következtetéseivel, eredményeivel. A tanulmányban a hosszú távú vállalati kapcsolatok általános jellemzését követően a kapcsolatok értékelésében megnyilvánuló vállalati szemléletmódot elemezzük, kiemelve, hogy a vállalatvezetők véleménye szerint a stabilitás, a kiszámíthatóság szempontjai általában elsődlegesek a kapcsolatokban rejlő együttműködési, fejlesztési lehetőségekhez képest. Különböző jellemzők (pl. vállalatméret, tulajdonos, teljesítmény) alapján kialakított csoportok véleményét összevetve rámutatunk, hogy az üzleti kapcsolatok megítélésében, a partnerek felé megjelenő elvárásokban a vállalatvezetők szemléletmódjában milyen eltérések észlelhetők. A tanulmány utolsó fejezetében a vevő-szállító kapcsolatokat támogató teljesítménymérési és -menedzsment eszköztárat értékeltük: a kedvező tendenciák, javuló támogatás ellenére sem állítható, hogy megfelelő, hatékony támogatást nyújtanak a vállalati információs és kontrolling rendszerek e kapcsolatok menedzseléséhez. A kutatás eredményeinek elemzése alapján látható, hogy az üzleti kapcsolatokra irányuló növekvő figyelem még kiaknázatlan lehetőségekkel párosul: a szemléletmód és a gyakorlat további fejlődése szükséges, hogy az üzleti kapcsolatok értékteremtő tényezőként a versenyképesség megalapozását, fejlesztését szolgálhassák a vállalatok szélesebb köre számára. ___________ The paper analyses the business relationships characteristics of Hungarian companies, based on data of the Competitiveness research program. Our goal was to characterize the business relationships and the causes of long term contracts and to analyse the view of different executives concerning the value of customer and supplier relationships. The last chapter of the paper evaluate the supporting role of performance measurement and management practice in the development of business relationships.

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.

An examination of the relationship of governance structure and performance: Evidence from banking companies in Bangladesh

Corporate governance has become increasingly important in developed and developing countries just after a series of corporate scandals and failures in a number of countries. Corporate governance structure is often viewed as a means of corporate success despite prior studies reveal mixed, somewhere conflicting and ambiguous, and somewhere no relationship between governance structure and performance. This study empirically investigates the relationship between corporate governance mechanisms and financial performance of listed banking companies in Bangladesh by using two multiple regression models. The study reveals that a good number of companies do not comply with the regulatory requirements indicating remarkable shortfall in corporate governance practice. The companies are run by the professional managers having no duality and no ownership interest for which they are compensated by high remuneration to curb agency conflict. Apart from some inconsistent relationship between some corporate variables, the corporate governance mechanisms do not appear to have significant relationship with financial performances. The findings reveal an insignificant negative impact or somewhere no impact of independent directors and non-independent non-executive directors on the level of performance that strongly support the concept that the managers are essentially worthy of trust and earn returns for the owners as claimed by stewardship theory. The study provides support for the view that while much emphasis on corporate governance mechanisms is necessary to safeguard the interest of stakeholders; corporate governance on its own, as a set of codes or standards for corporate conformance, cannot make a company successful. Companies need to balance corporate governance mechanisms with performance by adopting strategic decision and risk management with the efficient utilization of the organization’s resources.

The Role of Marketing in Corporate Competitiveness: Marketing Practice Analysis of Hungarian Companies

The objective of this article is to analyse the marketing practice of Hungarian companies. On the one hand, the role of marketing function in the company has been revealed, and on the other hand the relationship between marketing efforts and market performance has been investigated. In frame of the Hungarian Competitiveness Studies, 300 marketing executives were surveyed to rate the marketing practice of their companies, concentrating on branding, pricing policy, applied marketing channels and promotional activities. The results confirm that sophisticated marketing practice leads to higher business performance. Keywords: marketing tools, competitiveness, performance

Content and drivers of performance management in agency-type organizations of the hungarian public administration

The improving performance of public administration and the reform of public financing system have been on agenda in Hungary for many years, in accordance with the international trends. However, governments have not expected and supported creating of a performance-oriented public administration in a comprehensive and explicit way. Nevertheless, there are bottom-up initiatives at organizational level, which target performance-oriented organizational function. The research focuses on organizations of central public administration where the successful application of performance management methods is most likely based on the international literature. These are the so called agency-type organizations, which are in Hungary called autonomous state-administration organizations independent of the Government (e.g. Hungarian Competition Authority), government bureaus (e.g. Hungarian Central Statistical Office), and central offices subordinated to the government (either the cabinet or a ministry) (e.g. Hungarian Meteorological Service). The studied agencies are legally independent organizations with managerial autonomy based on public law. The purpose of this study is to get an overview on organizational level performance management tools applied by Hungarian agencies, and to reveal the reasons and drivers of the application of these tools. The empirical research is based on a mixed methods approach which combines both quantitative methods and qualitative procedures. The first – quantitative – phase of the author’s research was content analysis of homepages of the studied organizations. As a results she got information about all agencies and their practice related to some performance management tools. The second – qualitative – phase was based on semi-structured face-to-face interviews with some senior managers of agencies. The author selected the interviewees based on the results of the first phase, the relatively strong performance orientation was an important selection criteria.

Equity policy, educational practice, and limited English proficient (LEP) students in two high schools in Miami

Most studies of language minority students' performance focus on students' characteristics. This study uses qualitative methodology to examine instead how educational policies and practices affect the tracking of language minority students who are classified as limited English proficient (LEP). The placement of LEP students in core courses (English, Math, Social Studies, and Science) is seen as resulting from the interaction between school context and student characteristics. The school context includes factors such as equity policy requirements, overcrowding, attitudes regarding immigrants' academic potential, tracking, and testing practices. Interaction among these factors frequently leads to placement in lower track courses. It was found that the absence of formal tracks could be misleading to immigrant students, particularly those with high aspirations who do not understand the implications of the informal tracking system. Findings are discussed in relation to current theoretical explanations for minority student performance. ^
