An Approach for a more Objective Evaluation of Practical Projects, Used in the Training Process

Well–prepared, adaptive and sustainably developing specialists are an important competitive advantage, but also one of the main challenges for businesses. One option of the education system for creation and development of staff adequate to the needs is the development of pro jects with topics from real economy ("Practical Projects"). The objective assessment is an essential driver and motivator, and is based on a system of well-chosen, well-defined and specific criteria and indicators. An approach to a more objective evaluation of practical projects is finding more objective weights of the criteria. A natural and reasonable approach is the accumulation of opinions of proven experts and subsequent bringing out the weights from the accumulated data. The preparation and conduction of a survey among recognized experts in the field of project-based learning in mathematics, informatics and information technologies is described. The processing of the data accumulated by applying AHP, allowed us to objectively determine weights of evaluation criteria and hence to achieve the desired objectiveness.

Adaptációra vállalkozni – avagy vállalkozói szerepek megjelenése a környezet és az alkalmazkodás viszonyában (Attempting to adapt – Entreprenurial roles in the adaptation process to environmental changes)

A szerző cikkében arra a kérdésre keresi a választ, hogy a kis- és középvállalkozások vezetőinek sajátos környezethez fűződő viszonyát alapul véve milyen vállalkozói szerepek azonosíthatóak a környezeti változásokra való reagálás során. A kutatás központi kérdése, hogy a vállalkozó miként tekint magára az adaptációra a turbulensen változó környezeti viszonyok között, és magának milyen szerepet szán az alkalmazkodási folyamat során. A cikk bemutatja a vállalkozó személyiségének alapvető vonásait, külön kitérve a vállalkozó vezető személyére, majd ezt követően az adaptáció legjellemzőbb formáit és tulajdonságait helyezi középpontba. A tanulmány 14 hazai kis- és középvállalkozás vezetőjével készített interjú feldolgozásával, valamint Hortoványi és Szabó (2006a) adaptációs stratégiai típusai alapján három kategóriát azonosít a környezetfelfogás és reagálás kontextusában. ______ This paper focuses on the role of the entrepreneur in the adaptation process, how we can determine the role of the entrepreneur to environmental changes and to strategic adaptation itself. The paper begins with the presentation of the entrepreneurial models, focusing on the entrepreneurial management afterwards continues with a brief summary of the adaptation approach to strategy. Emphasizing that adaptation to changes can vary as innovation or entrepreneurship is concerned. Proactivity presents an adaptation strategy and moreover can be related to entrepreneurial behaviour and therefore characterizes the viewpoint of the entrepreneur. Entrepreneurs have to react to the changing environmental with analysis and proactive reaction, as future and innovation orientation is an integrate part of their entrepreneurial personality. Examining 14 interviews made with Hungarian entrepreneurs the paper identifies three categories which determine the role of the entrepreneurs in the adaptation process.

Relative importance of false positives in the selection process

This study investigated the role of contextual factors in personnel selection. Specifically, I explored if specific job factors such as the wage, training, available applicant pool and security concerns around a job, influenced personnel decisions. Additionally, I explored if the individual differences of decision makers played a role in how the previously mentioned job factors affected their decisions. A policy-capturing methodology was employed to determine the weight participants place on the job factors when selecting candidates for different jobs. Regression and correlational analyses were computed with the beta weights obtained from individual regression analyses. The results obtained from the two samples (student and general population) revealed that specific job characteristics did indeed influence personnel decisions. Participants were more concerned with making mistakes and thus less likely to accept candidates when selecting candidates for jobs having high salary and/or high training requirements.

Metacognitive Functions, Interest, and Student Engagement in the Writing Process: A Review of the Literature

The purpose of this paper is to draw on research that discusses the relationship between interest and metacognitive functions and its effect on engaging students in the writing process. Results indicate students who are interested in their writing activities engage in metacognitive strategies, remain focused, and complete their tasks.

Self -regulated learning: The role of a journal in the learning process for students and teachers

A fundamental goal of education is to equip students with self-regulatory capabilities that enable them to educate themselves. Self directedness not only contributes to success in formal instruction but also promotes lifelong learning (Bandura, 1997). The area of research on self-regulated learning is well grounded within the framework of psychological literature attributed to motivation, metacognition, strategy use and learning. This study explored past research and established the purpose of teaching students to self-regulate their learning and highlighted the fact that teachers are expected to assume a major role in the learning process. A student reflective writing journal activity was sustained for a period of two semesters in two fourth-grade mathematics classrooms. The reflective writing journal was analyzed in search of identifying strategies reported by students. Research questions were analyzed using descriptive statistics, frequency counts, cross-tabs and chi-square analyses. ^ Results based on student-use of the journals and teacher interviews indicated that the use of a reflective writing journal does promote self-regulated learning strategies to the extent which the student is engaged in the journaling process. Those students identified as highly self-regulated learners on the basis of their strategy use, were shown to consistently claim to learn math “as well or better than planned” on a weekly basis. Furthermore, good self-regulators were able to recognize specific strategies that helped them do well and change their strategies across time based on the planned learning objectives. The perspectives of the participating teachers were examined in order to establish the context in which the students were working. The effect of “planned change” and/or the resistance to change as established in previous research, from the teachers point of view, was also explored. The analysis of the journal data did establish a significant difference between students who utilized homework as a strategy. ^ Based on the journals and interviews, this study finds that the systematic use of metacognitive, motivational and/or learning strategies can have a positive effect on student's responsiveness to their learning environment. Furthermore, it reflects that teaching students “how to learn” can be a vital part of the effectiveness of any curriculum. ^

Using modeling as a co-design approach in the planning process of new care environments

Current research shows a relationship between healthcare architecture and patient-related Outcomes. The planning and designing of new healthcare environments is a complex process; the needs of the various end-users of the environment must be considered, including the patients, the patients’ significant others, and the staff. The aim of this study was to explore the experiences of healthcare professionals participating in group modelling utilizing system dynamics in the pre-design phase of new healthcare environments. We engaged healthcare professionals in a series of workshops using system dynamics to discuss the planning of healthcare environments in the beginning of a construction, and then interviewed them about their experience. An explorative and qualitative design was used to describe participants’ experiences of participating in the group modelling projects. Participants (n=20) were recruited from a larger intervention study using group modeling and system dynamics in planning and designing projects. The interviews were analysed by qualitative content analysis. Two themes were formed, representing the experiences in the group modeling process: ‘Partaking in the G-M created knowledge and empowerment’and ‘Partaking in the G-M was different from what was expected and required time and skills’. The method can support participants in design teams to focus more on their healthcare organization, their care activities and their aims rather than focusing on detailed layout solutions. This clarification is important when decisions about the design are discussed and prepared and will most likely lead to greater readiness for future building process.

Modelling interacting phenomena during the solidification of metals in the casting process

A variety of interacting complex phenomena takes place during the casting of metallic components. Here molten metal is poured into a mould cavity where it flows, cools, solidifies and then deforms in its solid state. As the metal cools, thermal gradients will promote thermal convection which will redistribute the heat around the component (usually from feeders or risers) towards the solidification front and mushy zone. Also, as the evolving solid regions of the cast component deform they will form gap at the cast-mould interface. This gap may change the rate of solidification in certain parts the casting, hence affecting the manner in which the cast component solidifies. Interaction between a cast component and its surrounding mould will also govern stress magnitudes in both the cast and mould -these may lead to defects such as cracks. This paper presents a multiphysics modelling approach to this complex process. Emphasis will be placed on the interacting phenomena taking place during the process and the modelling strategy used. Comparisons with plant data are also be given.

Understanding the role of CAP proteins in the polarization process of C. elegans

La division cellulaire asymétrique est un processus crucial dans le développement des organismes multicellulaires puisqu’elle permet la génération de la diversité cellulaire. Les cellules qui se divisent de façon asymétrique doivent tout d’abord se polariser et correctement orienter leur fuseau mitotique pour ségréger des déterminants cellulaires en deux entités distinctes. L’embryon du nématode C. elegans est un modèle robuste et largement utilisé pour étudier la division cellulaire asymétrique. Dans cet embryon, le point d'entrée du spermatozoïde détermine l'axe de polarité antéro-postérieur. Suite à la fécondation, le cortex embryonnaire est uniformément contractile et un complexe conservé formé des protéines PAR-3, PAR-6 et PKC-3 (nommé complexe PAR-3 ci-dessous) est localisé sur l'ensemble du cortex. La complétion de la méiose maternelle induit une relaxation corticale au postétieur et un flux cortical vers l’antérieur de l’embryon. Ces contractions corticales asymétriques mènent à la formation d'un domaine antérieur contenant le complexe PAR-3, tandis que le cortex postérieur, dont le complexe PAR-3 s’est délocalisé, est enrichi avec les protéines PAR-2 et PAR-1. Par conséquent, les domaines formés par les protéines PAR définissent un pôle antérieur et un pôle postérieur dans l'embryon suite au remodelage du cytosquelette. Les protéines PAR-4 et PAR-5 restent localisées de façon uniforme dans l'embryon. Curieusement, les protéines PAR exercent une régulation par rétroaction sur la contractilité corticale. Il a été montré qu’une des protéines PAR récemment identifiée, PAR-5, est orthologue à la protéine adaptatrice 14-3-3 et joue un rôle important dans la contractilité corticale. En dépit de son rôle central dans la contractilité corticale et le processus de polarisation cellulaire, le mécanisme par lequel PAR-5 régule la contractilité corticale n’est pas bien compris. Le but de ce projet est de mieux comprendre comment PAR-5 et ses interacteurs contrôlent la régulation des contractions corticales et, de ce fait, la polarité cellulaire. Dans un essai de capture de la protéine GST (GST pull-down), nous avons identifié plusieurs nouveaux interacteurs de PAR-5. Parmi ceux-ci, nous avons trouvé CAP-2 (protéine de coiffage de l'actine), qui a été identifiée dans des éxpériences de capture de 14-3-3 dans trois systèmes modèles différents. CAP-2 est un hétérodimère des protéines CAP, qui sont impliquées dans la régulation de l'actine. Nous avons trouvé que la déplétion des protéines CAP par interférence à l’ARN dans des vers de type sauvage mène à une augmentation létalité embryonnaire, ce qui suggère que ces protéines jouent un rôle important dans le développement embryonnaire. L'imagerie en temps réel d'embryons déplétés pour les protéines CAP montre qu’ils ont une diminution des contractions corticales avec un sillon de pseudoclivage mois stable, suggérant un défaut dans la régulation du cytosquelette d'actine-myosine. Ceci a également été confirmé par la diminution de la vitesse et du nombre de foci de NMY-2::GFP. En outre, ces embryons montrent une légère diminution de la taille du croissant cortical de PAR-2 lors de la phase d’établissement de la polarité. Les embryons déplétés en CAP-2 montrent également un retard dans la progression du cycle cellulaire, mais le lien entre ce phénotype et la régulation des contractions corticales reste à être précisé. La caractérisation des protéines CAP, des régulateurs du remodelage du cytosquelette, permettra d'améliorer notre compréhension des mécanismes qui sous-tendent l'établissement et le maintien de la polarité cellulaire, et donc la division cellulaire asymétrique.

The complexity in the implementation process of empowerment-based chronic kidney care: a case study

Background: This study is part of an interactive improvement intervention aimed to facilitate empowerment-based chronic kidney care using data from persons with CKD and their family members. There are many challenges to implementing empowerment-based care, and it is therefore necessary to study the implementation process. The aim of this study was to generate knowledge regarding the implementation process of an improvement intervention of empowerment for those who require chronic kidney care. Methods: A prospective single qualitative case study was chosen to follow the process of the implementation over a two year period. Twelve health care professionals were selected based on their various role(s) in the implementation of the improvement intervention. Data collection comprised of digitally recorded project group meetings, field notes of the meetings, and individual interviews before and after the improvement project. These multiple data were analyzed using qualitative latent content analysis. Results: Two facilitator themes emerged: Moving spirit and Encouragement. The healthcare professionals described a willingness to individualize care and to increase their professional development in the field of chronic kidney care. The implementation process was strongly reinforced by both the researchers working interactively with the staff, and the project group. One theme emerged as a barrier: the Limitations of the organization. Changes in the organization hindered the implementation of the intervention throughout the study period, and the lack of interplay in the organization most impeded the process. Conclusions: The findings indicated the complexity of maintaining a sustainable and lasting implementation over a period of two years. Implementing empowerment-based care was found to be facilitated by the cooperation between all involved healthcare professionals. Furthermore, long-term improvement interventions need strong encouragement from all levels of the organization to maintain engagement, even when it is initiated by the health care professionals themselves.

The Fairness of Media Coverage in Question: An Analysis of Referendum Campaigns on Welfare State Issues in Switzerland

The mass media are assigned an important role in political campaigns on popular votes. This article asks how the press communicates political issues to citizens during referendum campaigns, and whether some minimal criteria for successful public deliberation are met. The press coverage of all 24 ballot votes on welfare state issues from 1995 to 2004 in Switzerland is examined, distinguishing seven criteria to judge how news coverage compares to idealized notions of the media's role in the democratic process: coverage intensity, time for public deliberation, balance in media coverage, source independence and inclusiveness, substantive coverage, and spatial homogeneity. The results of our quantitative analysis suggest that the press does fulfil these normative requirements to a reasonable extent and that fears about biased or deceitful media treatment of ballot issues are not well-founded. However, some potential for optimizing the coverage of referendum campaigns by the Swiss press does exist

Political Influence, Economic Interests and Endogenous Tax Structure in a Computable Equilibrium Framework: with Applicatioon to the United States, 1973 and 1983

A full understanding of public affairs requires the ability to distinguish between the policies that voters would like the government to adopt, and the influence that different voters or group of voters actually exert in the democratic process. We consider the properties of a computable equilibrium model of a competitive political economy in which the economic interests of groups of voters and their effective influence on equilibrium policy outcomes can be explicitly distinguished and computed. The model incorporates an amended version of the GEMTAP tax model, and is calibrated to data for the United States for 1973 and 1983. Emphasis is placed on how the aggregation of GEMTAP households into groups within which economic and political behaviour is assumed homogeneous affects the numerical representation of interests and influence for representative members of each group. Experiments with the model suggest that the changes in both interests and influence are important parts of the story behind the evolution of U.S. tax policy in the decade after 1973.

Smallholder pig production systems along a periurban-rural gradient in the Western provinces of the Democratic Republic of the Congo

In the Democratic Republic of the Congo (DRC), pigs are raised almost exclusively by smallholders either in periurban areas of major cities such as Kinshasa or in rural villages. Unfortunately, little information is available regarding pig production in the Western part of the DRC, wherefore a survey was carried out to characterize and compare 319 pig production systems in their management and feeding strategies, along a periurban - rural gradient inWestern provinces of the DRC. Pig breeding was the main source of income (43%) and half of respondents were active in mixed pig and crop production, mainly vegetable garden. Depending on the location, smallholders owned on average 18 pigs, including four sows. Piglet mortality rate varied from 9.5 to 21.8% while average weaned age ranged between 2.2 and 2.8 months. The major causes of mortality reported by the farmers were African swine fever 98 %, swine erysipelas (60 %), erysipelas trypanosomiasis (31 %), swine worm infection (17 %), and diarrhoea (12 %). The majority of the pigs were reared in pens without free roaming and fed essentially with locally available by-products and forage plants whose nature varied according with the location of the farm. The pig production systems depended on the local environment; particularly in terms of workforces, herd structure and characteristics, production parameters, pig building materials, selling price and in feed resources. It can be concluded that an improvement of Congolese pig production systems should consider (1) a reduction of inbreeding, (2) an improvement in biosafety to reduce the incidence of African swine fever and the spread of other diseases, and (3) an improvement in feeding practices.

The rise of Islamism amongst Muslim youth in the UK

The purpose of this study was to examine the possible reasons why Muslim youth are increasingly becoming attracted to radical Islam in the UK. Recent studies involving focus groups of Muslim youth across the UK and opinion surveys were used to measure youth's level of religious guidance, integration in society and feelings of hostility or of an enemy image of Islam. It was found that alienation from traditional methods of religious education, parents/ imams, is the possible first step that makes youth more vulnerable to outside Islamist groups. The second step is the lack of integration due to discrimination and feeling as an enemy within society. The enemy image includes the government's decision to invade Iraq and the perception that Muslims and Islam are under attack. There is a strong need for youth to reconcile their national and religious identities in order to be active citizens in the future.
