competition argue for a more even spread of resources to also support pockets of excellence found in smaller universities. A central question in this debate (Harrison 2009 ) is whether there exists a critical mass in research and, if so, what is it? Here we

A cikk a társadalmi mozgalmakkal foglalkozik. Azt vizsgálja, hogy az ifjúsági társadalom elmúlt negyedszázadában milyen mozgalmi csírákat azonosíthattunk. A fogalmi magyarázatot követően a cikk arra koncentrált, hogy ezek a mozgalmak milyen sikereket, kudarcokat értek el, és miként befolyásolták az ifjúság általános beállítódását. Nyilvánvalóan fontos e téren az országos hallgatói képviselet és az alternatív hallgatói mozgalom, leginkább a HaHa és ennek középiskolai változatának elemzése. Érdekes, és külön vizsgálandó kérdés, hogy az ifjúsági társadalom nyertes és vesztes csoportjaiban azonosított két szubkultúra, a kuruc.info és a Critical Mass tudott-e mozgalommá fejlődni, és ha igen, hogyan változtatta meg a magyar fiatalok politikai közgondolkodását.

This paper argues that there are conditions for successful euro area (EA) accession, apart from fiscal rectitude. One is an ex ante critical mass of real convergence which should enhance lasting nominal convergence. Another condition is an overhaul of EA mechanisms and policies that should make it a properly functioning monetary union, which implies an adequate mix between risk-reduction and risk-sharing. It is argued that risk-sharing cannot be secured by private sector arrangements only. Entering the ERM2 is deemed to be no less demanding than euro area accession per se, especially for countries that use fl exible exchange rate regimes. The paper examines also the infl uence of production (value) chains on the efficacy of autonomous monetary and exchange rate policies when it comes to controlling external imbalances; macro-prudential policies, too, are highlighted in this regard. Steady productivity gains are a must for surmounting the middle income trap and achieving sustainable real convergence.

e-Procurement adoption by architects in the Nigerian building industry was investigated using data derived via a questionnaire survey of 75 architects in consulting and contracting firms, government and clients’ organizations. The data were analyzed using descriptive statistics, Pearson product-moment correlation and content analyses, and the results reveal that most of the organizations employing architects were not using e-Procurement. However, the very few adopters identified used e-mails and websites in communicating, exchanging project information, and sourcing for building services, materials and equipment. The key barriers to the uptake of e-Procurement among architects in the survey were unreliable power supply, low level of awareness among people; and the lack of forum to exchange ideas on e- Procurement use. The paper emphasized the need to address these challenges to ensure a critical mass uptake of e-Procurement by architects in Nigeria.

Abstract  

The scientific production measured by the number of mainstream joint publications, resulting from the cooperative research efforts between Chile and Spain, considering disciplines, application field, type of journal, impact factor, and research institutions involved, was analyzed for the 1991-2000 period. Databases from several institutions, such as the Institute for Scientific Information (ISI) in USA and other national organizations, were employed to quantify the number of publications and to determine the profile of the mutual-collaboration research groups of both countries. It was possible to establish the strong points of the mutual work in some disciplines and the formation of a critical mass of researchers, showing that the scientific cooperation between countries of emerging-economies, like Chile, and developed nations, as Spain, is possible and leads to mutual benefits.

Abstract  

The aim of this study was to draw attention to the possible existence of "quirk", inbibliographic databases and to discuss their implications. We analysed the time-trends of"publication types" (PTs) relating to clinical medicine in the most frequently searched medicaldatabase, MEDLINE. We counted the number of entries corresponding to 10 PTs indexed inMEDLINE (1963-1998) and drew up a matrix of [10 PTs × 36 years] which we analysed bycorrespondence factor analysis (CFA). The analysis showed that, although the "internal clock" ofthe database was broadly consistent, there were periods of erratic activity. Thus, observed trendsmight not always reflect true publication trends in clinical medicine but quirks in MEDLINEindexing of PTs. There may be, for instance, different limits for retrospective tagging of entriesrelating to different PTs. The time-trend for Reviews of Reported Cases differed substantiallyfrom that of other publication types.Despite the quirks, quite rational explanations could be provided for the strongest correlationsamong PTs. The main factorial map revealed how the advent of the Randomised Controlled Trial(RCT) and the accumulation of a critical mass of literature may have increased the rate ofpublication of research syntheses (meta-analyses, practice guidelines...). The RCT is now theiogold standardls in clinical investigation and is often a key component of formal "systematicreviews" of the literature. Medical journal editors have largely contributed to this situation andthus helped to foster the birth and development of a new paradigm, "evidence based medicine"which assumes that expert opinion is biased and therefore relies heavily — virtually exclusively —on critical analysis of the peer-reviewed literature. Our exploratory factor analysis, however, leadsus to question the consistency of MEDLINEs indexing procedures and also the rationale forMEDLINE's choice of descriptors. Databases have biases of their own, some of which are notindependent of expert opinion. User-friendliness should not make us forget that outputs depend onhow the databases are constructed and structured.

The acceleratory effect of potassium perchlorate on the reactivity of the red lead-silicon system has been studied by employing DTA and DSC. Supporting investigations on pure potassium perchlorate and the binary system red lead-potassium perchlorate suggest that the complex decomposition kinetics of potassium perchlorate drastically influences the oxidation of silicon. Further, the ternary system also undergoes a transition from exothermic smooth decomposition to ignition at a certain critical mass, as noted in the red lead-silicon and iron(III) oxide system. The criticality should be a result of the rise in temperature expressed as a perturbation of the steady-state energy conservation conditions, as postulated by Gray.

Bevezetés: A rezidensévek az orvosi hivatás egyik legnagyobb kihívást jelentő időszaka. Célkitűzés: Jelen vizsgálat a hazai rezidensnők (n = 380) munkamegterhelésére, munkával való elégedettségére és kiégésének feltérképezésére irányult. Módszer: Orvosok körében végzett országos reprezentatív felmérés, rezidensekre vonatkozó eredményeinek bemutatása. Az adatok szélesebb körű értelmezése céljából a válaszadó férfi rezidenseket (n = 176) kontrollcsoportként vonták be az elemzésbe. Eredmények: A rezidensnők átlagos munkaideje heti 66 óra volt, és 70%-uk túlterheltnek érezte magát. A közepes és magas fokú kiégés legnagyobb arányban a teljesítményvesztés dimenziójában jelentkezett (75,9%), ezt követte 58%-os aránnyal az érzelmi kimerülés komponense, majd a deperszonalizáció faktora (53%). A rezidensek legkevésbé munkakörülményeikkel, anyagi helyzetükkel és munkájuk nem anyagi, illetve anyagi elismerésével voltak elégedettek. A magyar egészségügyi rendszerrel való elégedetlenség mintegy 80%-os arányt mutatott, és a válaszadók közel negyede fontolgatta a külföldi munkavállalást. Következtetések: A fiatal orvosok „derékhadát” alkotó rezidensnők munkával való elégedettsége és kiégése közvetve és közvetlenül is a betegellátás meghatározó indikátora. Orv. Hetil., 2014, 155(46), 1831–1840.
