A relação entre o ambiente institucional, a gestão de recursos humanos e os resultados organizacionais

Esta tese tem como objetivo verificar as similaridades e diferenças nas práticas de Gestão De Recursos Humanos (GRH) adotadas em empresas inseridas em diferentes tipos de Ambientes Institucionais e suas relações com a percepção dos Resultados Organizacionais. Para isso, adotou-se como premissas: (i) as forças institucionais advindas do Ambiente Institucional brasileiro fazem com que as práticas de GRH das empresas que operam neste contexto tendam a convergir apresentando similaridades e que, concomitantemente, (ii) as forças oriundas das pressões do Ambiente Institucional dos países de origem das empresas fazem com que as práticas de GRH tendam a divergir das práticas locais, apresentando diferenças. Buscou-se embasamento em três teorias: a teorias da Variedades de Capitalismo; a Teoria do Sistema Nacional de Negócios e a tipologia de Economia de Mercado Hierárquico operante na América Latina, Brasil. De natureza positivista, este estudo descritivo e de abordagem contextualista contou com uma população de aproximadamente 22.052 organizações e amostra de 326 empresas. Realizou-se uma survey e fez-se uso de técnicas descritivas e de modelagem de equações estruturais no tratamento e na análise dos dados coletados. Constatou-se que, em geral, há mais similaridades do que diferenças nas práticas de GRH das empresas que operam no Brasil, indo ao encontro da premissa (i). Validou-se que o Ambiente Institucional afeta a GRH no Brasil e esta influencia na percepção dos Resultados Organizacionais das empresas, tanto as com sedes corporativas localizadas no Brasil quanto as com sede em países com economia de mercado liberal. Entretanto, a GRH não demonstrou ser influente nas organizações com sede corporativa localizadas em países de economia coordenada. Comprovou-se que a GRH faz a mediação da relação entre o Ambiente Institucional e os Resultados Organizacionais. Como contribuições, aos práticos destaca-se a reflexão sobre a forma como a GRH concebe suas práticas, quais os limites do papel da área e seu favorecimento à competitividade das empresas. Para a Rede Cranet e acadêmicos, somam-se as evidências sobre o Brasil e seu Ambiente Institucional, ainda pouco explorado. Acredita-se, também, que as análises contribuem para a tomada de decisões dos líderes empresariais ao envolver a relação ambiente e empresa. A contribuição social desta tese situa-se na possibilidade de seu uso em discussões sobre Políticas Públicas referentes a emprego, trabalho, renda, economia e educação.

Why Are German Employers Associations Declining? A Challenge to the Conventional Wisdom. CES Germany & Europe Working Papers, No. 05.3, 2005

This paper challenges the conventional explanation for declining density of German employers associations. The dominant account asserts that German trade unions have taken advantage of increased globalization since the 1980s which has made internationally active enterprises more vulnerable to production disruptions to extract additional monopoly rents from multinational employers via aggressive collective bargaining. Small firms have responded to the increased union pressures by avoiding membership employers associations, which has produced the density declines. Data, however, disconfirm the conventional explanation; compensation increases have actually become increasingly smaller over the decades. This paper presents an alternative explanation that is consistent with the data. We argue that it is the large product manufacturers rather than the trade unions that have greatly increased price pressures on parts suppliers, which has led to a disproportionate number of suppliers to quit employers associations. The paper also discusses these findings in light of the "varieties of capitalism" literature. It points out that this literature has depicted national models as too homogeneous. The decision of several German employers associations to offer different classes of membership represents an accentuation of variety within national varieties of capitalism.

Niemcy jako koordynowana gospodarka rynkowa. Wymiary transformacji i perspektywy rozwoju

Przedmiotem artykułu są zmiany, jakie nastąpiły w niemieckim modelu koordynowanej gospodarki rynkowej od początku XXI wieku. Za najważniejsze z nich uznano: reformy Agendy 2010, wzrost roli zewnętrznej polityki ekonomicznej w polityce zagranicznej Niemiec oraz rozwiązania instytucjonalne, takie jak jednolity rynek wewnętrzny oraz strefa euro, które stworzyły jakościowo nowy kontekst funkcjonowania gospodarki Niemiec. Przedstawiając perspektywy rozwoju modelu koordynacyjnego postawiono tezę, iż zmiany w gospodarce niemieckiej następować będą przede wszystkim pod wpływem presji ze strony pozostałych państw europejskich, w tym zwłaszcza partnerów z Unii Gospodarczej i Walutowej, a także w odpowiedzi na problemy wewnętrzne, takie jak konieczność modernizacji infrastruktury, zwiększenia inwestycji oraz wzrostu płac. Badanie prowadzone jest metodą jakościową i odwołuje się do perspektywy instytucjonalnej różnorodności kapitalizmu (varieties of capitalism).

The Coming of Post-reflexive Society: Commodification and Language in Digital Capitalism

Language is a unique aspect of human communication because it can be used to discuss itself in its own terms. For this reason, human societies potentially have superior capacities of co-ordination, reflexive self-correction, and innovation than other animal, physical or cybernetic systems. However, this analysis also reveals that language is interconnected with the economically and technologically mediated social sphere and hence is vulnerable to abstraction, objectification, reification, and therefore ideology – all of which are antithetical to its reflexive function, whilst paradoxically being a fundamental part of it. In particular, in capitalism, language is increasingly commodified within the social domains created and affected by ubiquitous communication technologies. The advent of the so-called ‘knowledge economy’ implicates exchangeable forms of thought (language) as the fundamental commodities of this emerging system. The historical point at which a ‘knowledge economy’ emerges, then, is the critical point at which thought itself becomes a commodified ‘thing’, and language becomes its “objective” means of exchange. However, the processes by which such commodification and objectification occurs obscures the unique social relations within which these language commodities are produced. The latest economic phase of capitalism – the knowledge economy – and the obfuscating trajectory which accompanies it, we argue, is destroying the reflexive capacity of language particularly through the process of commodification. This can be seen in that the language practices that have emerged in conjunction with digital technologies are increasingly non-reflexive and therefore less capable of self-critical, conscious change.

Varieties generated by modular lattices of width four

A variety (equational class) of lattices is said to be finitely based if there exists a finite set of identities defining the variety. Let M^∞_n denote the lattice variety generated by all modular lattices of width not exceeding n. M^∞₁ and M^∞₂ are both the class of all distributive lattices and consequently finitely based. B. Jónsson has shown that M^∞₃ is also finitely based. On the other hand, K. Baker has shown that M^∞_n is not finitely based for 5 ≤ n ˂ ω. This thesis settles the finite basis problem for M^∞₄. M^∞₄ is shown to be finitely based by proving the stronger result that there exist ten varieties which properly contain M^∞₄ and such that any variety which properly contains M^∞₄ contains one of these ten varieties.

The methods developed also yield a characterization of sub-directly irreducible width four modular lattices. From this characterization further results are derived. It is shown that the free M^∞₄ lattice with n generators is finite. A variety with exactly k covers is exhibited for all k ≥ 15. It is further shown that there are 2^Ӄo sub- varieties of M^∞₄.

Fast Discrimination of Commerical Corn Varieties Based on Near Infrared Spectra

The existing methods for the discrimination of varieties of commodity corn seed are unable to process batch data and speed up identification, and very time consuming and costly. The present paper developed a new approach to the fast discrimination of varieties of commodity corn by means of near infrared spectral data. Firstly, the experiment obtained spectral data of 37 varieties of commodity corn seed with the Fourier transform near infrared spectrometer in the wavenurnber range from 4 000 to 12 000 cm (1). Secondly, the original data were pretreated using statistics method of normalization in order to eliminate noise and improve the efficiency of models. Thirdly, a new way based on sample standard deviation was used to select the characteristic spectral regions, and it can search very different wavenumbers among all wavenumbers and reduce the amount of data in part. Fourthly, principal component analysis (PCA) was used to compress spectral data into several variables, and the cumulate reliabilities of the first ten components were more than 99.98%. Finally, according to the first ten components, recognition models were established based on BPR. For every 25 samples in each variety, 15 samples were randomly selected as the training set. The remaining 10 samples of the same variety were used as the first testing set, and all the 900 samples of the other varieties were used as the second testing set. Calculation results showed that the average correctness recognition rate of the 37 varieties of corn seed was 94.3%. Testing results indicate that the discrimination method had higher precision than the discrimination of various kinds of commodity corn seed. In short, it is feasible to discriminate various varieties of commodity corn seed based on near infrared spectroscopy and BPR.

Capitalism, the state and health care in the age of austerity:A Marxist analysis

The capacity to provide satisfactory nursing care is being increasingly compromised by current trajectories of healthcare funding and governance. The purpose of this paper is to examine how well Marxist theories of the state and its relationship with capital can explain these trajectories in this period of ever-increasing austerity. Following a brief history of the current crisis, it examines empirically the effects of the crisis, and of the current trajectory of capitalism in general, upon the funding and organization of the UK and US healthcare systems. The deleterious effect of growing income inequalities to the health of the population are also addressed. Marx’s writings on the state and its relation to the capitalist class were fragmentary, and historically and geographically specific. From them, we can extract three theoretical variants: the instrumentalist theory of the state, where the state has no autonomy from capital; the abdication theory, whereby capital abstains from direct political power and relies on the state to serve its interests; and the class-balance theory of the state, whereby the struggle between two opposed classes allows the state to assert itself. Discussion of modern Marxist interpretations include Poulantzas’s structuralist abdication theory and Miliband’s instrumentalist theory. It is concluded that, despite the pluralism of electoral democracies, the bourgeoisie do have an overweening influence upon the state. The bourgeoisie’s ownership of the means of production provides the foundation for its influence because the state is obliged to rely on it to manage the supply of goods and services and the creation of wealth. That power is further reinforced by the infiltration of the bourgeoisie into the organs of state. The level of influence has accelerated rapidly over recent decades. One of the consequences of this has been that healthcare systems have become rich pickings for the evermore confident bourgeoisie.

Geographies of Communality, Colonialism, and Capitalism: Ecology and the World-System

Drawing upon recent reworkings of world systems theory and Marx’s concept of metabolic rift, this paper attempts to ground early nineteenth-century Ireland more clearly within these metanarratives, which take the historical-ecological dynamics of the development of capitalism as their point of departure. In order to unravel the socio-spatial complexities of Irish agricultural production throughout this time, attention must be given to the prevalence of customary legal tenure, institutions of communal governance, and their interaction with the colonial apparatus, as an essential feature of Ireland’s historical geography often neglected by famine scholars. This spatially differentiated legacy of communality, embedded within a country-wide system of colonial rent, and burgeoning capitalist system of global trade, gave rise to profound regional differentiations and ecological contradictions, which became central to the distribution of distress during the Great Famine (1845-1852). Contrary to accounts which depict it as a case of discrete transition from feudalism to capitalism, Ireland’s pre-famine ecology must be understood through an analysis which emphasises these socio-spatial complexities. Consequently, this structure must be conceptualised as one in which communality, colonialism, and capitalism interact dynamically, and in varying stages of development and devolution, according to space and time.

Isolating the 'farmer' effect as a component of the advantage of growing genetically modified varieties in developing countries: a Bt cotton case study from Jalgaon, India

The present paper explores the 'farmer' effect in economic advantages often claimed for Bt cotton varieties (those with the endotoxin gene from Bacillus thuringiensis conferring resistance to some insect pests) compared to non-Bt varieties. Critics claim that much of the yield advantage of Bt cotton could be due to the fact that farmers adopting the technology are in a better position to provide inputs and management and so much of any claimed Bt advantage is an artefact rather than reflecting a real advantage of the variety per se. The present paper provides an in-depth analysis of 63 non-adopting and 94 adopting households of Bt cotton in Jalgaon, Maharashtra State, India, spanning the seasons 2002 and 2003. Results suggest that Bt adopters are indeed different from non-adopters in a number of ways. Adopters appear to specialize more on cotton (at least in terms of the land area they devote to the crop), spend more money on irrigation and grow well-performing non-Bt varieties of cotton (Bunny). Taking gross margin as the basis for comparison, Bt plots had 2.5 times the gross margin of non-Bt plots in both seasons. If only adopters are considered then the gross margin advantage of Bt plots reduces to 1.6 times that of non-Bt plots. This is still a significant advantage and could well explain the popularity of Bt in Maharashtra. However, it is clear that great care needs to be taken with such comparative studies.

Concentrations of free amino acids and sugars in nine potato varieties: effects of storage and relationship with acrylamide formation

Acrylamide forms during cooking and processing predominately from the reaction of free asparagine and reducing sugars in the Maillard reaction. The identification of low free asparagine and reducing sugar varieties of crops is therefore an important target. In this study, nine varieties of potato (French fry varieties Maris Piper (from two suppliers), Pentland Dell, King Edward, Daisy, and Markies; and chipping varieties Lady Claire, Lady Rosetta, Saturna, and Hermes) grown in the United Kingdom in 2009 were analyzed at monthly intervals through storage from November 2009 to July 2010. Acrylamide formation was measured in heated flour and chips fried in oil. Analysis of variance revealed significant interactions between varieties nested within type (French fry and chipping) and storage time for most free amino acids, glucose, fructose, and acrylamide formation. Acrylamide formed in chips correlated significantly with acrylamide formed in flour and with chip color. There were significant correlations between glucose or total reducing sugar concentration and acrylamide formation in both variety types, but with fructose the correlation was much stronger for chipping than for French fry varieties. Conversely, there were significant correlations with acrylamide formation for both total free amino acid and free asparagine concentration in the French fry but not chipping varieties. The study showed the potential of variety selection for preventing unacceptable levels of acrylamide formation in potato products and the variety-dependent effect of long-term storage on acrylamide risk. It also highlighted the complex relationship between precursor concentration and acrylamide risk in potatoes.

Chronic limitations of neo-liberal capitalism and oligopolistic markets: an urgent case for socialized capital

Purpose – The purpose of this paper is to highlight the serious limitations of neo-liberal capitalism and urge for a shift to socialized capital before further economic deterioration leads to a succession of global conflicts. Design/methodology/approach – This conceptual paper adopts a macro perspective in presenting argument on how global, financial markets integration and capital flow liberalization have led to inadequate market and corporate governance measures. The argument is couched in a selected literature and is preceded by a proposed solution – the requirement for socialized capital. An analysis of the nature of socialized capital is outlined and the questions that require attention identified if a paradigm shift from neo-liberal capitalism is to take place. Findings – The need to urgently shift to a new philosophy of capitalism is overwhelming. Emphasized is that capital needs to adopt a socialised identity and is supported by investment horizons of 30 years or more. It is argued that non-market (e.g. state, NGOs, civil society) intervention is critical in setting appropriate frameworks within which socialized capital can operate. Research limitations/implications – This is a theoretical paper, in which questions are raised which require transparent, public debate. Originality/value – The paper presents the case for a fundamental reconsideration of present day markets, the role of capital and the influence of elites in determining the public good.

Acrylamide in potato crisps prepared from 20 UK-grown varieties: effects of variety and tuber storage time

Twenty varieties of field-grown potato were stored for 2 months and 6 months at 8 °C. Mean acrylamide contents in crisps prepared from all varieties at both storage times ranged from 131 μg per kg in Verdi to 5360 μg per kg in Pentland Dell. In contrast to previous studies, the longer storage period did not affect acrylamide formation significantly for most varieties, the exceptions being Innovator, where acrylamide formation increased, and Saturna, where it decreased. Four of the five varieties designated as suitable for crisping produced crisps with acrylamide levels below the European Commission indicative value of 1000 μg per kg (Saturna, Lady Rosetta, Lady Claire, and Verdi); the exception was Hermes. Two varieties more often used for French fries, Markies and Fontane, also produced crisps with less than 1000 μg per kg acrylamide. Correlations between acrylamide, its precursors and crisp colour are described, and the implications of the results for production of potato crisps are discussed.
