As Relações Padrasto e Enteado: aspectos psicodinâmicos

Este estudo teve por objetivos, identificar a percepção do padrasto sobre suas relações com seu(s) enteado(s) e identificar a percepção do padrasto acerca da sua função e papel na família. Utilizou-se de uma investigação clínica de referencial psicanalítico que levantou os dados por meio de entrevistas semi-dirigidas e do Desenho de família com estórias, em 3 participantes adultos e que eram padrastos. Os atendimentos foram realizados em ambiente de consultório, respeitando-se questões técnicas e éticas da pesquisa e da Psicologia em especial, tais como sigilo e consentimento dos participantes. A análise do conteúdo mostrou que havia peculiaridades em cada caso estudado, entretanto, havia fatores comuns em seus sentimentos e ações sobre a família e enteados: a) houve uma ambivalência pois tanto se perceberam como homens provedores e orientadores dos filhos e enteados, quanto havia também uma a percepção de que os sentimentos pelo filho biológico eram diferentes daqueles sentidos por seus enteados. b) todos os padrastos revelaram entraves nas relações por uma não definição clara de seu papel e função no contexto familiar, muitas vezes reforçado pelas esposas- mães, tidas como aquelas que detém o poder sobre o filho/enteado e, esta confusão gerava rivalidade entre padrasto e enteado, numa disputa pelo amor da esposa e mãe. c) do ponto de vista psíquico, foi observado que muitos conflitos os remetiam aos períodos precoces do desenvolvimento, especialmente à resolução edipiana, como numa reedição; assim, o exercício da função de padrasto se dá à base da qualidade de suas relações com seus pais na infância tal como se dá no exercício da paternidade consangüínea. De modo que, a função de padrasto, assim como a paterna se dá por um compromisso evolutivo . Sugerem-se outros trabalhos, pois se entendeu que esse tipo de estudo relacionado à Psicologia do desenvolvimento pode auxiliar em ações de saúde e prevenção em saúde mental.

Psychophysical evidence for two routes to suppression before binocular summation of signals in human vision

Visual mechanisms in primary visual cortex are suppressed by the superposition of gratings perpendicular to their preferred orientations. A clear picture of this process is needed to (i) inform functional architecture of image-processing models, (ii) identify the pathways available to support binocular rivalry, and (iii) generally advance our understanding of early vision. Here we use monoptic sine-wave gratings and cross-orientation masking (XOM) to reveal two cross-oriented suppressive pathways in humans, both of which occur before full binocular summation of signals. One is a within-eye (ipsiocular) pathway that is spatially broadband, immune to contrast adaptation and has a suppressive weight that tends to decrease with stimulus duration. The other pathway operates between the eyes (interocular), is spatially tuned, desensitizes with contrast adaptation and has a suppressive weight that increases with stimulus duration. When cross-oriented masks are presented to both eyes, masking is enhanced or diminished for conditions in which either ipsiocular or interocular pathways dominate masking, respectively. We propose that ipsiocular suppression precedes the influence of interocular suppression and tentatively associate the two effects with the lateral geniculate nucleus (or retina) and the visual cortex respectively. The interocular route is a good candidate for the initial pathway involved in binocular rivalry and predicts that interocular cross-orientation suppression should be found in cortical cells with predominantly ipsiocular drive. © 2007 IBRO.

An interpretive approach to analysing the role and value of information systems in Jordanian financial organisations

Analysing investments in ISs in order to maximise benefits has become a prime concern, especially for private corporations. No formula of equilibrium exists that could link the injected amounts and accrued returns. The relationship is simply not straightforward. This thesis is based upon empirical work which involved sketching organisational ethnographies (four organographies and a sectography) into the role and value of information systems in Jordanian financial organisations. Besides deciphering the map of impacts, it explains the attributions of the variations in the impacts of ISs which were found to be related to the internal organisational processes: culturally and politically specific considerations, economically or technically rooted factors and environmental factors. The research serves as an empirical attempt to test out the applicability of adopting the interpretive paradigm to researching organisations in a developing country. The fieldwork comprised an exploratory stage, a detailed investigation of four case studies and a survey stage encompassing 16 organisations. Primary and secondary data were collected from multiple sources using a range of instruments. The evidence highlights the fact that little long term strategic planning was pursued; the emphasis was more focused on short term planning. There was no noticeable adoption of any strategic fit principle linking IS strategy to the corporate strategy. In addition, the benefits obtained were mostly intangible. Although ISs were central to the work of the organisations surveyed as the core technology, they were considered as tools or work enablers rather than weapons for competitive rivalry. The cultural specificity of IS impacts was evident and the cultural and political considerations were key factors in explaining the attributions of the variations in the impacts of ISs in JFOs. The thesis confirms that measuring the benefits of ISs is the problematic. However, in order to gain more insight, the phenomenon of "the use of ISs" has to be studied within its context.

The effect of interocular phase difference on perceived contrast

Binocular vision is traditionally treated as two processes: the fusion of similar images, and the interocular suppression of dissimilar images (e.g. binocular rivalry). Recent work has demonstrated that interocular suppression is phase-insensitive, whereas binocular summation occurs only when stimuli are in phase. But how do these processes affect our perception of binocular contrast? We measured perceived contrast using a matching paradigm for a wide range of interocular phase offsets (0–180°) and matching contrasts (2–32%). Our results revealed a complex interaction between contrast and interocular phase. At low contrasts, perceived contrast reduced monotonically with increasing phase offset, by up to a factor of 1.6. At higher contrasts the pattern was non-monotonic: perceived contrast was veridical for in-phase and antiphase conditions, and monocular presentation, but increased a little at intermediate phase angles. These findings challenge a recent model in which contrast perception is phase-invariant. The results were predicted by a binocular contrast gain control model. The model involves monocular gain controls with interocular suppression from positive and negative phase channels, followed by summation across eyes and then across space. Importantly, this model—applied to conditions with vertical disparity—has only a single (zero) disparity channel and embodies both fusion and suppression processes within a single framework.

La politique linguistique et l'avenir du Francais au Mexique:etude du cas de l'universite de Veracruz

In a linguistic context where it seems the entire world is only interested in learning English, it is worth considering the idea of whether French still has a place in Mexico. In spite of the predominance of English, there is nevertheless a feeling that French remains alive in Mexico, and indeed in certain areas has retained its strength and appeal. This hypothesis was to put to the test by exploring the current linguistic environment prevalent in the state of Veracruz. An investigation in the form of questionnaires and interviews of all those connected to the teaching of French (including students, teachers and employees and directors of language schools) shows that the desire of the Mexican government of promoting English for everyone is not necessarily consistent with the desire and expectations of the general populace. This in turn suggest the need of adopting a policy that enables us not only to take into consideration what people seem to be telling us regarding the learning of foreign learning but also of what they are not telling us. If the teaching and learning of French as a foreign language remains strong in Veracruz, it is explained much more by the long and friendly relationship that people in the state have had with French people (and their culture) than it is by any instrumental needs of learning their language. This is seen in the fact that students here consistently describe their motivation for learning French from an emotional or affective standpoint rather than from professional one. It seems that the ties between the Mexican and French people remain solid. Another interesting characteristic of students of French in Veracruz is the positive attitude they seem to have regarding languages in general, which in turn enables them to take further advantage of the benefits made available from globalization. In reality, there exists no rivalry between French and English and therefore it is unnecessary to adopt measures that would address such struggle. It is however a matter of great urgency that authorities in the arenas of politics and academia take a closer look at the policies they design regarding the study of foreign languages in general, and that they consider, specifically, a wholly alternative to the one language model of teaching and learning of foreign language – in this case English-, a model that for all intents and purposes has failed. In the midst of a globalized world, and during this current period of increased linguistic activity, the aforementioned assertions serve not only to support my initial hypothesis, but also to help shake off the dust of some out-dated belief systems and lay down the framework for a new, better informed and well thought-out policy of foreign languages planning.

Market orientation of hotels and travel services in China

China is unique both politically and economically. How this uniqueness impacts on firms'' adoption of market orientation and the impact of market orientation on business performance, however, remain unclear. This book reports a study by Dr Riliang Qu who aims to address the above knowledge void. The study employs a two-stage research strategy including interviews and a survey of 1000 hotels and travel services. The study found that government regulations restricting the firm rivalry and the shortage of competent managerial talents are among the most serious constraints to the firms'' development of market orientation along with such factors as inadequacy of government regulation on product quality and consumer protection. The findings suggest that in transitional like China, government actions could be a major force behind firms'' aspiration of being market-oriented. The study also found that the benefits of market orientation are multi-fold in that it not only improves company''s business performance but also has positive effects on customer satisfaction/retention, power in distribution channel, and corporate social responsibility.

Systematic financial resources allocation processes:a model for critical resources mobilization and deployment for nigerian universities

Purpose – The purpose of this research is to study the perceived impact of some factors on the resources allocation processes of the Nigerian universities and to suggest a framework that will help practitioners and academics to understand and improve such processes. Design/methodology/approach – The study adopted the interpretive qualitative approach aimed at an ‘in-depth’ understanding of the resource allocation experiences of key university personnel and their perceived impact of the contextual factors affecting such processes. The analysis of individual narratives from each university established the conditions and factors impacting the resources allocation processes within each institution. Findings – The resources allocation process issues in the Nigerian universities may be categorised into people (core and peripheral units’ challenge, and politics and power); process (resources allocation processes); and resources (critical financial shortage and resources dependence response). The study also provides insight that resourcing efficiency in Nigerian universities appears strongly constrained by the rivalry among the resource managers. The efficient resources allocation process (ERAP) model is proposed to resolve the identified resourcing deficiencies. Research limitations/implications – The research is not focused to provide generalizable observations but ‘in-depth’ perceived factors and their impact on the resources allocation processes in Nigerian universities. The study is limited to the internal resources allocation issues within the universities and excludes the external funding factors. The resource managers’ responses to the identified factors may affect their internal resourcing efficiency. Further research using more empirical samples is required to obtain more widespread results and the implications for all universities. Originality/value – This study contributes a fresh literature framework to resources allocation processes focusing at ‘people’, ‘process’ and ‘resources’. Also a middle range theory triangulation is developed in relation to better understanding of resourcing process management. The study will be of interest to university managers and policy makers.

Megjegyzések a „nemzeti versenyképesség” koncepciójához és méréséhez

A vállalati, pontosabban szólva az üzleti szemléletmód persze nagymértékben indokolhatja a fejlődés koncepciójának versenyképességi koncepcióként való felfogását és a hangsúlynak a vállalatok működése, hatékonysága és eredményessége szempontjából meghatározó szerepű belső mikró- és makró-gazdasági körülményekre helyezését, sőt, a vonatkozó mutatószámok létjogosultságát is. Mindez azonban nem lehet mentség a nemzetek, illetve országok fejlődésének és a feltételezetten közöttük folyó versenynek a fölöttébb leegyszerűsítő és egyoldalú értelmezésére. _________ The working paper is the analysis of understanding and measurement of competitiveness in critical view. Competitiveness has become a very fashionable term recently, used not only in regard to the marketing of products or services, and the rivalry of enterprises but also concerning nations or rather countries. The study reviews the understanding of competitiveness, the role of corporate transnationalization and the opportunities of measurement and assessment of national competitiveness. There are several understanding of competitiveness of nations or countries, and there are also many indices to measure it. The understanding of national competitiveness is many times confused with economic development.

Hiánygazdaság − többletgazdaság. Tanulmány a piac elméletéről – II. rész = Shortage economy - surplus economy. A study on market theory II

A főáramlat közgazdászai elismerik, hogy a szocialista rendszert a krónikus hiány jellemezte, de úgy vélik, hogy a kapitalista rendszerben - kisebb vagy nagyobb ingadozások közepette - piaci egyensúly uralkodik. Ezzel szemben a tanulmány két piaci állapotot állít egymással szembe. Az egyikben dominálnak a túlkeresleti jelenségek, bár előfordulnak túlkínálati jelenségek is, ezt nevezi a szerző hiánygazdaságnak. A másikban dominálnak a túlkínálati jelenségek, bár előfordulnak túlkeresleti jelenségek is, amit a szerző többletgazdaságnak nevez. A tanulmány II. része összefoglalja a tanulmány fő állításait. Ezek szerint a szocialista rendszer veleszületett immanens tulajdonsága a hiánygazdaság, míg a kapitalista rendszer veleszületett immanens tulajdonsága a többletgazdaság létrehozása és állandó reprodukciója. Állami beavatkozások erősíthetik vagy gyengíthetik ezeket a genetikus tulajdonságokat, de nem szüntethetik meg. A tanulmány áttekinti a többletgazdaság kedvező és kedvezőtlen hatásait. A kedvező hatások között különleges nyomatékkal emeli ki, hogy a többlet (elsősorban többletkapacitások) nélkül nem alakulhat ki a termelők, illetve az eladók rivalizálása, ami az innovációs folyamat legfontosabb hajtóereje. A többletgazdaság általános esetének vizsgálata után különböző speciális esetekkel foglalkozik a tanulmány: a gazdaság konjunkturális hullámzásával, a hadigazdasággal, a modern kapitalizmusban mutatkozó történelmi léptékű változásokkal, valamint a szocialista rendszeren belül megjelent piacorientált reformokkal és a posztszocialista átmenettel. ____ Mainstream economists recognize that the socialist system was marked by chronic shortage, but they consider that the capitalist system exhibits market equilibrium, give or take some greater or lesser fluctuations. This study, however, contrasts two market states. One is dominated by phenomena of excess demand, though instances of excess supply appear as well; this the author calls a shortage economy. The other is dominated by phenomena of excess supply, though instances of excess demand appear as well; this the author terms a surplus economy. Part II of the study starts by summing up its main propositions. Just as the shortage economy is an intrinsic, immanent trait of the socialist system, so the creation and continual reproduction of the surplus economy is an intrinsic, immanent trait of the capitalist system. Such genetic traits may be strengthened or weakened by state intervention, but not eliminated by it. The study reviews the favourable and detrimental effects of the surplus economy. Of the favourable effects, it is emphasized that without surplus there cannot develop among producers or sellers the rivalry that provides the main impetus for the innovation process. Having examined the general case of the surplus economy, the study turns to various special cases: to the trade-cycle fluctuations of the economy, the war economy, the historic changes appearing in modern capitalism, the market-oriented reforms that appear within the socialist system, and the post-socialist transition.

Kornai DRSE-elmélete versus általános egyensúlyelmélet

Kornai János az ex post modellfilozófiát követte a DRSE-elméletében (Kornai, 2014), amely gyökeresen szakít az uralkodó neoklasszikus iskola ex ante feltételrendszerével, a szigorú egyensúlyi keretekkel, és saját premisszákat fogalmaz meg a kapitalista gazdaság működésére. Vagyis a DRSE-elmélet egy nagyon újszerű irányzatot jelöl ki a közgazdasági iskolák között. Az elmélet még csak verbális modellként értelmezhető, tartópillérei a kapitalista rendszer immanens jellemzői: a dinamizmus, a rivalizálás és a többletgazdaság. (Ezek angol megfelelőinek, a Dynamism, Rivalry, Surplus Economy kezdőbetűi szerepelnek az elmélet megnevezésében.) A többletgazdaság, azaz a túlkínálat dominanciáját a monopolista verseny, a kereslet nagyságának bizonytalansága, a schumpeteri innováció, dinamizmus, technikai haladás, teremtő rombolás, valamint a növekvő skálahozadék, a termelők és a szolgáltatók között a piacokért folyó rivalizálás váltja ki. E cikk célkitűzése, hogy megvizsgálja a DRSE-elmélet formális matematikai modellként történő megfogalmazásának lehetőségét. Ebben sajátos utat választottunk: először feltárjuk az általános egyensúlyelmélet (Walras, 1874; Neumann, 1945) irreális ex ante feltevéseit, majd megállapítjuk a DRSE premisszái közötti lehetséges összefüggéseket, amelyekben meghatározó kikötés, hogy csakúgy, mint a biológiai evolúcióban, a piacgazdaság evolúciós folyamataiban sincs fix egyensúlyi állapot, még referenciapontként sem. Az általános egyensúlyelmélet és a DRSE-elmélet egybevetése a schumpeteri evolúciós közgazdaságtan fókuszában történik.

Kornai’s DRSE Theory Versus General Equilibrium Theory

János Kornai’s DRSE theory (Kornai, 2014) follows the ex post model philosophy which radically rejects the ex ante set of conditions laid down by the dominant neoclassical school and the stringent limits of equilibrium, and defines its own premises for the functioning of capitalist economy. In other words, the DRSE theory represents an extremely novel trend among the various schools of economics. The theory is still only a verbal model with the following supporting pillars as the immanent features of the capitalist system: dynamism, rivalry and the surplus economy. (The English name of the theory uses the initial letters of the terms Dynamism, Rivalry, Surplus Economy). The dominance of the surplus economy, that is, oversupply is replaced by monopolistic competition, uncertainty over the volume of demand, Schumpeterian innovation, dynamism, technological progress, creative destruction and increasing return to scale with rivalry between producers and service providers for markets. This paper aims to examine whether the DRSE theory can be formulated as a formal mathematical model. We have chosen a special route to do this: first we explore the unreal ex ante assumptions of general equilibrium theory (Walras, 1874; Neumann, 1945), and then we establish some of the possible connections between the premises of DRSE, which include the crucial condition that just like in biological evolution, there is no fixed steady state in the evolutionary processes of market economy, not even as a point of reference. General equilibrium theory and DRSE theory are compared in the focus of Schumpeterian evolutionary economics.

Pivot or periphery? Xinjiang's regional development and Chinese-Central Asian relations at the century's end

Xinjiang, once described by Owen Lattimore as the "pivot of Asia", has played a strategically important role in China's national defense and security. Historically linked on the famous Silk Road with Central Asia, Xinjiang was crucial to East-West economic and cultural exchanges. During the period of Russian/Soviet expansion into Central Asia and Sino-Soviet rivalry, China's need for Xinjiang's defense and territorial integrity became paramount, and consequently Xinjiang's economy was relegated to the periphery.^ The demise of the Soviet Union--which resulted in the independence of five Central Asian states--and China's reform suggest dramatic new possibilities for Xinjiang's regional development as well as interregional cooperation. As China has begun to shift regional emphasis to the interior, Xinjiang's economic development will be accelerated. With the growth of Sino/Xinjiang-Central Asian relations, Xinjiang's importance will not only be borne out in terms of defense and security, but more significantly in terms of trade and economics. At the century's end and the beginning of the 21st century, Xinjiang will likely move away from the periphery and play an increasingly pivotal role in the economy. ^

On the fundamentals of research and development (R&D) spillovers in competitive markets

Rivals may voluntarily share Research and Development (R&D) results even in the absence of any binding agreements or collusion. In a model where rival firms engage in non-cooperative independent R&D process, we used optimization and game theory analysis to study the equilibrium strategy of the firms. Our work showed that, while minimal spillover is always equilibrium, there may be another equilibrium where firms may reciprocally choose high, sometimes perfect, spillover rates. The incentive for sharing R&D output is based on firms' expectations of learning from their rivals' R&D progress in the future. This leads to strategic complementarities between the firms' choices of spillover rates and thus policy implication follows. ^ Public research agencies can contribute more to social welfare by providing research as public goods. In a non-cooperative public-private research relationship where parallel R&D is conducted, by making its R&D results accessible, the public research agency can stimulate private spillovers, even if there exists rivalry among the private firms who can benefit from such spillovers. ^

Oman's foreign policy: Foundations and practice

The object of this dissertation is to record and analyze the foreign policy of the Sultanate of Oman from the early twentieth century until 2004. It challenges the central assumption of the contemporary scholarship on the subject that Muscat's modern foreign policy begins in 1970. It is often presumed that the pre-1970 era does not merit a thorough investigation to understand Muscat's modus operandi today. This study argues that for a comprehensive understanding of Muscat's foreign policy since 1970, the frontier of the historical analysis of Oman's regional and international involvement should be pushed back to the 1930's, when the young Sultan Said assumed power over the country divided by the "Treaty" or the "Agreement" of Sib. Indeed, the thrust of this research lies at once in repudiating the conventional wisdom regarding both the persona of Sultan Said and the customary political/historical narrative of Said's reign. The critical analysis of this period is utilized to rebut the pervasive and largely inaccurate historical narrative of the events prior to 1970, to recount an original interpretation of the period, and to use the narrative as a preamble for subsequent foreign policy directions and initiatives. Furthermore, this dissertation covers the gaps in the literature resulting from the absence of any materials that either record or analyze Muscat's foreign policy from 1996 until 2004. In addition, his study provides new information and a fresh analysis of the international relations of the region, including great power rivalry, especially the competition between the United States and Great Britain, and the attitudes of major regional actors, such as Iran, Saudi Arabia, and Iraq. ^ The use of a thorough historical inquiry is vital to support the central claim of this dissertation; therefore, a large section of this dissertation is based almost exclusively on archival materials collected from the British Public Records Office, the University of Oxford and the Library of Congress. This project represents the most comprehensive use of archival materials on the subject matter to date. ^
