Políticas de contenção de desmatamento, produção e mercado de terras na Amazônia: um ensaio sobre a economia local do sudeste paraense usando contas sociais alfa (CSα)

A discussão atual sobre a emissão de carbono associada ao uso agropecuário da terra em prejuízo de florestas se ressente de uma visão sistêmica, no que se refere aos fluxos econômicos propriamente, e suas interações, no que tange ao ambiente institucional que os garante. Dado que os esquemas de compensação implicam a entrada e saída de recursos em contextos econômicos amplos e sistêmicos, fundamental é discutir qual o resultado final desses fluxos sobre as condições gerais de reprodução das economias locais. As questões básicas são: a) como tais políticas poderão, a partir dos setores rurais, afetar a demanda final efetiva e, por essa via, o valor da produção e as variáveis de valor adicionado de toda a economia e b) como as variações na economia afetam as formas de uso da base natural e, portanto, o desmatamento. No que se refere às instituições, o artigo dá especial ênfase às que definem o mercado de terras, porque nele encontra o cerne de questões vitais para o que se discute. O artigo utiliza um modelo ascendente de geração de matrizes de insumo-produto para a economia local do Sudeste Paraense, incorpora nela um balanço de carbono dos setores da produção rural, encontra os multiplicadores e simula quatro situações de politica de contenção de desmatamento e redução das emissões de gases poluentes. A conclusão principal do artigo é que se faz necessário pensar políticas de contenção de desmatamento ligadas indissociavelmente a políticas de produção – a serem operadas por mecanismos que façam convergir as decisões dos agentes com perspectivas macro de desenvolvimento: local, endógeno e sustentável.

Diagnóstico da gestão e do gerenciamento dos resíduos eletroeletrônicos gerados no campus da Faculdade de Engenharia de Guaratinguetá/Unesp

Currently, in Brazil, the quantity and quality of new types of wastes, discarded without criteria in urban areas, has been responsible for considerable impacts on public health and the environment. According to a report prepared by the Institute of Applied Economic Research (IPEA), the country loses about U.S. $ 8 billion annually, due lack of waste recycling, which go directly into landfills or dumps. Among these solid wastes are waste electrical and electronic equipment (WEEE), whose characteristics are complex, by having in its composition substances of high value-added and other health hazards which require different treatment of household waste. Aiming to fill the gap in Brazilian environmental legislation, on 02/08/2010, was sanctioned the National Policy Solid Waste (Law No. 12,305), already regulated on 23/12/2010 (Decree No 7404), whose based on the following principles:reduction of waste generation and toxicity of shared responsibility, proper planning management, social inclusion of waste pickers and sustainable production and consumption. Given the above, this work presented here, aims generally present a diagnosis of the current situation of electronic waste generated in the Faculty of Engineering, Campus Guaratinguetá, FEG / UNESP, to provide data for management and management of these waste, based on sustainability, the economic losses and minimizing environmental impacts and public health related to the flow and the improper disposal of these wastes

Influência da adição de fator de crescimento fibroblástico 10 (FGF10), durante a maturação oocitária, na produção in vitro de embriões bovinos

The Brazilian livestock stands out for having the world largest commercial herd of cattle and leads meat exportation and production of bovine embryos. The in vitro production (IVP) of embryos is considered an effective option to overcome problems such as infertility in cows with high economic value and also for genetic improvement of cattle. The in vitro oocyte maturation is an essential step to the success of IVP, but is still considered poor when compared to in vivo maturation. Recent studies have suggeested an important role of Fibroblast Growth Factor 10 (FGF10) on the in vitro maturation of oocytes, which favored the expression of genes related to oocyte maturation and cumulus cell expansion. Aware that maturity stage influences the final production of blastocysts, we aimed study to verify if the addition of FGF10 into the maturation medium is able to affect positively the IVP of bovine embryos. Hence, FGF10 was added to maturation in five different concentrations: 0.5 ng/mL (group 0.5), 2.5 ng/mL (group 2.5), 5 ng/mL (group 5), 10 ng/mL (group 10) and 50 ng/mL (group 50). Additionally, two other maturation groups were used, group BSA (Bovine Serum Albumin, 4 mg/mL) and group FCS (Fetal Calf Serum, 10%). The rates of cleavage, morula and blastocyst were analyzed by Analysis of Variance (ANOVA), differences of P<0.05 were considered significant. Cleavage rates did not differ between the seven groups. On the other hand, morula rate on FCS group was higher than groups BSA, 0.5, 10 and 50 (P<0.05), but did not differ among groups treated with intermediate doses of FGF10 (2.5 and 5). FCS group presented higher blastocyst rate compared to all other groups that were well below the FCS group (P<0.0001). Therefore, the use of FGF10 during oocyte maturation did not affect positively embryo development on the IVP of bovine embryos

Diagnóstico e proposição de medidas para o controle das perdas de água no sistema de abastecimento de Guaratinguetá

Over the past two years, Brazil has been facing a major water crisis in its history and the state of Sao Paulo is the one that has been going through worst difficulties. In this scenario, all water users should do everything possible so that the consumption of water resources is carried out in a sustainable manner. In this context, the companies responsible for the public water supply must increase the efficiency of water resource management. It is indispensable combating losses in the public supply system. When there is a non-visible leak in a pipe, the wastewater volume can be high, but in this case, the water returns to nature and continues to participate in the hydrological cycle. The economic loss corresponds to the value added to the product water, which includes the intrinsic costs of exploration, processing and distribution. This damage results in a reduced availability of financial resources of sanitation companies to invest in environmentally friendly solutions. This study aimed to diagnose the water distribution system in the city of Guaratinguetá (SP), held by the Companhia de Serviços de Água, Esgoto e Resíduos de Guaratinguetá (SAEG), to propose measures to combat water loss. Among the proposed measures, there is the monitoring of losses, planning for replacement of old pipes and company awareness as a whole in relation to combat water losses

The firm. Techno-organizational changes, industrial relations and performances. An enquiry on Reggio Emilia local industrial system

It is not unknown that the evolution of firm theories has been developed along a path paved by an increasing awareness of the organizational structure importance. From the early “neoclassical” conceptualizations that intended the firm as a rational actor whose aim is to produce that amount of output, given the inputs at its disposal and in accordance to technological or environmental constraints, which maximizes the revenue (see Boulding, 1942 for a past mid century state of the art discussion) to the knowledge based theory of the firm (Nonaka & Takeuchi, 1995; Nonaka & Toyama, 2005), which recognizes in the firm a knnowledge creating entity, with specific organizational capabilities (Teece, 1996; Teece & Pisano, 1998) that allow to sustaine competitive advantages. Tracing back a map of the theory of the firm evolution, taking into account the several perspectives adopted in the history of thought, would take the length of many books. Because of that a more fruitful strategy is circumscribing the focus of the description of the literature evolution to one flow connected to a crucial question about the nature of firm’s behaviour and about the determinants of competitive advantages. In so doing I adopt a perspective that allows me to consider the organizational structure of the firm as an element according to which the different theories can be discriminated. The approach adopted starts by considering the drawbacks of the standard neoclassical theory of the firm. Discussing the most influential theoretical approaches I end up with a close examination of the knowledge based perspective of the firm. Within this perspective the firm is considered as a knowledge creating entity that produce and mange knowledge (Nonaka, Toyama, & Nagata, 2000; Nonaka & Toyama, 2005). In a knowledge intensive organization, knowledge is clearly embedded for the most part in the human capital of the individuals that compose such an organization. In a knowledge based organization, the management, in order to cope with knowledge intensive productions, ought to develop and accumulate capabilities that shape the organizational forms in a way that relies on “cross-functional processes, extensive delayering and empowerment” (Foss 2005, p.12). This mechanism contributes to determine the absorptive capacity of the firm towards specific technologies and, in so doing, it also shape the technological trajectories along which the firm moves. After having recognized the growing importance of the firm’s organizational structure in the theoretical literature concerning the firm theory, the subsequent point of the analysis is that of providing an overview of the changes that have been occurred at micro level to the firm’s organization of production. The economic actors have to deal with challenges posed by processes of internationalisation and globalization, increased and increasing competitive pressure of less developed countries on low value added production activities, changes in technologies and increased environmental turbulence and volatility. As a consequence, it has been widely recognized that the main organizational models of production that fitted well in the 20th century are now partially inadequate and processes aiming to reorganize production activities have been widespread across several economies in recent years. Recently, the emergence of a “new” form of production organization has been proposed both by scholars, practitioners and institutions: the most prominent characteristic of such a model is its recognition of the importance of employees commitment and involvement. As a consequence it is characterized by a strong accent on the human resource management and on those practices that aim to widen the autonomy and responsibility of the workers as well as increasing their commitment to the organization (Osterman, 1994; 2000; Lynch, 2007). This “model” of production organization is by many defined as High Performance Work System (HPWS). Despite the increasing diffusion of workplace practices that may be inscribed within the concept of HPWS in western countries’ companies, it is an hazard, to some extent, to speak about the emergence of a “new organizational paradigm”. The discussion about organizational changes and the diffusion of HPWP the focus cannot abstract from a discussion about the industrial relations systems, with a particular accent on the employment relationships, because of their relevance, in the same way as production organization, in determining two major outcomes of the firm: innovation and economic performances. The argument is treated starting from the issue of the Social Dialogue at macro level, both in an European perspective and Italian perspective. The model of interaction between the social parties has repercussions, at micro level, on the employment relationships, that is to say on the relations between union delegates and management or workers and management. Finding economic and social policies capable of sustaining growth and employment within a knowledge based scenario is likely to constitute the major challenge for the next generation of social pacts, which are the main social dialogue outcomes. As Acocella and Leoni (2007) put forward the social pacts may constitute an instrument to trade wage moderation for high intensity in ICT, organizational and human capital investments. Empirical evidence, especially focused on the micro level, about the positive relation between economic growth and new organizational designs coupled with ICT adoption and non adversarial industrial relations is growing. Partnership among social parties may become an instrument to enhance firm competitiveness. The outcome of the discussion is the integration of organizational changes and industrial relations elements within a unified framework: the HPWS. Such a choice may help in disentangling the potential existence of complementarities between these two aspects of the firm internal structure on economic and innovative performance. With the third chapter starts the more original part of the thesis. The data utilized in order to disentangle the relations between HPWS practices, innovation and economic performance refer to the manufacturing firms of the Reggio Emilia province with more than 50 employees. The data have been collected through face to face interviews both to management (199 respondents) and to union representatives (181 respondents). Coupled with the cross section datasets a further data source is constituted by longitudinal balance sheets (1994-2004). Collecting reliable data that in turn provide reliable results needs always a great effort to which are connected uncertain results. Data at micro level are often subjected to a trade off: the wider is the geographical context to which the population surveyed belong the lesser is the amount of information usually collected (low level of resolution); the narrower is the focus on specific geographical context, the higher is the amount of information usually collected (high level of resolution). For the Italian case the evidence about the diffusion of HPWP and their effects on firm performances is still scanty and usually limited to local level studies (Cristini, et al., 2003). The thesis is also devoted to the deepening of an argument of particular interest: the existence of complementarities between the HPWS practices. It has been widely shown by empirical evidence that when HPWP are adopted in bundles they are more likely to impact on firm’s performances than when adopted in isolation (Ichniowski, Prennushi, Shaw, 1997). Is it true also for the local production system of Reggio Emilia? The empirical analysis has the precise aim of providing evidence on the relations between the HPWS dimensions and the innovative and economic performances of the firm. As far as the first line of analysis is concerned it must to be stressed the fundamental role that innovation plays in the economy (Geroski & Machin, 1993; Stoneman & Kwoon 1994, 1996; OECD, 2005; EC, 2002). On this point the evidence goes from the traditional innovations, usually approximated by R&D investment expenditure or number of patents, to the introduction and adoption of ICT, in the recent years (Brynjolfsson & Hitt, 2000). If innovation is important then it is critical to analyse its determinants. In this work it is hypothesised that organizational changes and firm level industrial relations/employment relations aspects that can be put under the heading of HPWS, influence the propensity to innovate in product, process and quality of the firm. The general argument may goes as follow: changes in production management and work organization reconfigure the absorptive capacity of the firm towards specific technologies and, in so doing, they shape the technological trajectories along which the firm moves; cooperative industrial relations may lead to smother adoption of innovations, because not contrasted by unions. From the first empirical chapter emerges that the different types of innovations seem to respond in different ways to the HPWS variables. The underlying processes of product, process and quality innovations are likely to answer to different firm’s strategies and needs. Nevertheless, it is possible to extract some general results in terms of the most influencing HPWS factors on innovative performance. The main three aspects are training coverage, employees involvement and the diffusion of bonuses. These variables show persistent and significant relations with all the three innovation types. The same do the components having such variables at their inside. In sum the aspects of the HPWS influence the propensity to innovate of the firm. At the same time, emerges a quite neat (although not always strong) evidence of complementarities presence between HPWS practices. In terns of the complementarity issue it can be said that some specific complementarities exist. Training activities, when adopted and managed in bundles, are related to the propensity to innovate. Having a sound skill base may be an element that enhances the firm’s capacity to innovate. It may enhance both the capacity to absorbe exogenous innovation and the capacity to endogenously develop innovations. The presence and diffusion of bonuses and the employees involvement also spur innovative propensity. The former because of their incentive nature and the latter because direct workers participation may increase workers commitment to the organizationa and thus their willingness to support and suggest inovations. The other line of analysis provides results on the relation between HPWS and economic performances of the firm. There have been a bulk of international empirical studies on the relation between organizational changes and economic performance (Black & Lynch 2001; Zwick 2004; Janod & Saint-Martin 2004; Huselid 1995; Huselid & Becker 1996; Cappelli & Neumark 2001), while the works aiming to capture the relations between economic performance and unions or industrial relations aspects are quite scant (Addison & Belfield, 2001; Pencavel, 2003; Machin & Stewart, 1990; Addison, 2005). In the empirical analysis the integration of the two main areas of the HPWS represent a scarcely exploited approach in the panorama of both national and international empirical studies. As remarked by Addison “although most analysis of workers representation and employee involvement/high performance work practices have been conducted in isolation – while sometimes including the other as controls – research is beginning to consider their interactions” (Addison, 2005, p.407). The analysis conducted exploiting temporal lags between dependent and covariates, possibility given by the merger of cross section and panel data, provides evidence in favour of the existence of HPWS practices impact on firm’s economic performance, differently measured. Although it does not seem to emerge robust evidence on the existence of complementarities among HPWS aspects on performances there is evidence of a general positive influence of the single practices. The results are quite sensible to the time lags, inducing to hypothesize that time varying heterogeneity is an important factor in determining the impact of organizational changes on economic performance. The implications of the analysis can be of help both to management and local level policy makers. Although the results are not simply extendible to other local production systems it may be argued that for contexts similar to the Reggio Emilia province, characterized by the presence of small and medium enterprises organized in districts and by a deep rooted unionism, with strong supporting institutions, the results and the implications here obtained can also fit well. However, a hope for future researches on the subject treated in the present work is that of collecting good quality information over wider geographical areas, possibly at national level, and repeated in time. Only in this way it is possible to solve the Gordian knot about the linkages between innovation, performance, high performance work practices and industrial relations.

Il ruolo della grande distribuzione nello sviluppo locale. Un'indagine sul contesto italiano

Supermarkets and hypermarkets still represent a relatively new retailing format in Italy and in its Southern area in particular, where they were introduced decades later than in other Western countries, such as France and the UK in Europe, and the US in America. Nowadays, these retailers have become large organisations potentially capable of influencing local development from an economic, social and urban perspective. The literature concerned with their effects on the local economy, in particular, has focused on labour markets, price dynamics, inter-type competition, instead the impact on macroeconomic factors such as GDP, value added and investments in specific sectors, as agriculture, industry and services. This study tries to fill this gap by empirically investigating associations between key characteristics of these retailers and specific macroeconomic factors.

Celestial Church of Christ in Italia. Percorsi, Spazi e Pratiche Rituali

Il lavoro che presento propone un’analisi di una chiesa africana indipendente in Italia, la Celestial Church Of Christ Worldwide (CCCW), cercando di mettere in luce il nesso tra religione, migrazione e il processo di ‘plunting churches’ (Kooning 2009) nel contesto italiano. Attraverso una ricerca sul campo, sono stati indagati i percorsi personali, familiari e comunitari dei membri di una ‘Celestial Parish’ presente nel comune di Brescia, ‘Ileri Oluwa Parish’, al fine di comprendere la natura dei processi identitari coinvolti nell’organizzazione della CCC in Italia. ‘Ileri Oluwa Parish’, in quanto luogo che denota una ‘chiesa individuale collegata ad una Diocesi’ (CCC Constitution (CCC Constitution, 107 (d) si rivela, nella materialità delle sue forme e dei ‘Devotional Services’ che in essa si svolgono, a ‘field of action’ (Lefebvre, 1991). La storia della chiesa, i fondamenti della sua dottrina e i significati comunicati attraverso le forme rituali e religiose che la stessa promuove, sono stati contestualizzati alla luce delle tensioni e delle strategie di potere che strutturano il campo. Le storie dei membri della parrocchia, percorsi di migrazione e mobilità in itinere, rappresentano la lente attraverso cui si è guardato alle relazioni vissute nel nome dello ‘Spirito’, e alla percezione stessa di ciò che gli stessi Celestians definiscono sacro, santo, puro e impuro. Lo sguardo fisso alla vita ordinaria di una Celestial parish in Italia, esteso nell’ultima parte dell’elaborato alla Celestial parish londinese, è stato fondamentale per capire l’intreccio di relazioni spirituali, reti familiari e mobilità degli individui sul territorio italiano ed europeo, processo che ribalta la condizione diasporica della CCC, trasformando una condizione di dispersione in un valore aggiunto, nella possibilità di nuove traiettorie territoriali e spazi di presenza religiosa e socioeconomica.

Effects of Initial Body Condition, Frame Size and Concentration of Dietary Energy on Carcass Value of Finished Steers

Yearling steers were sorted into four groups based on hip height and fat cover at the start of the finishing period. Each group of sorted steers was fed diets containing 0.59 or 0.64 Mcal NEg per pound of diet. The value of each carcass was determined by use of the Oklahoma State University Boxed Beef Calculator. Sorting to increase hip height decreased the percentage of Choice carcasses and fat cover, increased ribeye area, and had no effect on carcass weight or yield grades 1 and 2. Sorting to decrease initial fat cover decreased carcass weight, carcass fat cover, and percentage of choice carcasses and increased the proportion of yield grades 1 and 2 carcasses. Concentration of energy in the finishing diet had no effect on carcass measurements. Increasing the percentage of yield grades 1 and 2 carcasses did not result in increased economic value of the carcasses when quality grades were lower and when there was a wide spread between Choice and Select carcasses, as occurred in 1996. With less spread between Choice and Select, as in 1997, sorting the cattle to increase yield grades 1 and 2 resulted in increased value, especially for close-trim boxed beef. The results of this study emphasize the importance of knowing how carcasses will grade before selecting a valuebased market for selling cattle.
