Mudanças climáticas: o discurso da mídia sobre o aquecimento global

This research is aimed at discussing the ways in which social agents influence global warming, analyzing the discourse of social actors involved in the debate on climate change, since there is a wide divergence in the scientific community about how man is able to modify the climate on a global scale. In fact the debate that permeates the issues beyond the limits of science and enter into a political-economic framework that takes extraordinary proportions. This emphasis can be very unscientific in the fundamental design concepts, or even creating a trivialization of the media. The main way to convey these concepts is to disclose them in the media, but the media has enormous power to transform the concepts and often manipulate the news by creating a common sense goes against the interests of the scientific community. Thus was conducted extensive research in major newspapers and magazines that move in the country. We surveyed the first two papers which were: “Folha de S. Paulo” and “O Estado de S. Paulo”, during the period from January 2000 to December 2008, totaling 3285 units for the newspaper Folha and 2555 for the newspaper Estadão. Subsequently a survey was made of data published in two journals that move at the national level, and these are the magazines VEJA and ÉPOCA for the same period. By performing these steps, it was concluded that several factors involving the media and climate change, such as topic relevance, types of approaches, perspectives of analysis, the staff development, supplies, among other factors of utmost importance for building news. As a result we can say that the media in fulfilling its role of mediator scientific, disclosing only a vision that permeates the scientific debate. The newspaper media, especially newspapers, has an informative and instantaneous. Often this preoccupation...(Complete abstract, click electronic access below)

Interações metodológicas e interrelações humanas: alicerçando a transdisciplinaridade no campo da saúde no trabalho

This article provides reflections and discussions about the importance of human interactions and methodological interrelations to substantiate the integrity in the transdisciplinary process in teams that operate in health area. Should be taken as reference the Complexity Theory of Edgar Morin, the logic transdisciplinary of Basarab Nicolescu and the formation groups principles based on the Socionomic Theory of Jacob Levy Moreno. It was concluded that the complexity of the methodologies in the field of workplace health, are influenced by factors that intersect between the scientific interaction and human interrelationships, which allow the transdisciplinary construction. However, the constructions requires the development of professionals in their areas and in their relationship with others as a way of supporting the perspective of transdisciplinarity, ie, interaction, in which different individuals are interrelated with the methodologies and providing articulations and coconstructions from which actualize the transformations.

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.

Fattori di rischio biomeccanico e valori limite di esposizione (TLV-ACGIH®) nell’ambito dello studio di coorte della sindrome del tunnel carpale occupazionale

OBIETTIVI: Per esplorare il contributo dei fattori di rischio biomeccanico, ripetitività (hand activity level – HAL) e forza manuale (peak force - PF), nell’insorgenza della sindrome del tunnel carpale (STC), abbiamo studiato un’ampia coorte di lavoratori dell’industria, utilizzando come riferimento il valore limite di soglia (TLV©) dell’American Conference of Governmental Industrial Hygienists (ACGIH). METODI: La coorte è stata osservata dal 2000 al 2011. Abbiamo classificato l’esposizione professionale rispetto al limite di azione (AL) e al TLV dell’ACGIH in: “accettabile” (sotto AL), “intermedia” (tra AL e TLV) e “inaccettabile” (sopra TLV). Abbiamo considerato due definizioni di caso: 1) sintomi di STC; 2) sintomi e positività allo studio di conduzione nervosa (SCN). Abbiamo applicato modelli di regressione di Poisson aggiustati per sesso, età, indice di massa corporea e presenza di patologie predisponenti la malattia. RISULTATI: Nell’intera coorte (1710 lavoratori) abbiamo trovato un tasso di incidenza (IR) di sintomi di STC di 4.1 per 100 anni-persona; un IR di STC confermata dallo SCN di 1.3 per 100 anni-persona. Gli esposti “sopra TLV” presentano un rischio di sviluppare sintomi di STC di 1.76 rispetto agli esposti “sotto AL”. Un andamento simile è emerso per la seconda definizione di caso [incidence rate ratios (IRR) “sopra TLV”, 1.37 (intervallo di confidenza al 95% (IC95%) 0.84–2.23)]. Gli esposti a “carico intermedio” risultano a maggior rischio per la STC [IRR per i sintomi, 3.31 (IC95% 2.39–4.59); IRR per sintomi e SCN positivo, 2.56 (IC95% 1.47–4.43)]. Abbiamo osservato una maggior forza di associazione tra HAL e la STC. CONCLUSIONI: Abbiamo trovato un aumento di rischio di sviluppare la STC all’aumentare del carico biomeccanico: l’aumento di rischio osservato già per gli esposti a “carico intermedio” suggerisce che gli attuali valori limite potrebbero non essere sufficientemente protettivi per alcuni lavoratori. Interventi di prevenzione vanno orientati verso attività manuali ripetitive.

Audience Effects in COgnitive Task Performance in Capuchin Monkeys (Cebus apella)

Primates as a taxonomic Order have the largest brains corrected for body size in the animal kingdom. These large brains have allowed primates to evolve the capacity to demonstrate advanced cognitive processes across a wide array of abilities. Nonhuman primates are particularly adept at social learning, defined as the modification of behavior by observing the actions of others. Additionally, primates often exploit resources differently depending on their social context. In this study, capuchin monkeys (Cebus apella) were tested on a cognitive task in three social contexts to determine if social context influenced their performance on the task. The three social contexts included: alone, having a dominant individual in an adjacent compartment, and having a subordinate individual in the adjacent compartment. The benefits to this design were thatthe social context was the only variable influencing performance, whereas in previous studies investigating audience effects other animals could physically and directly influence a subject's performance in an open testing situation. Based on past studies, Ipredicted that the presence of a dominant individual would reduce cognitive task performance compared to the other conditions. The cognitive test used was a match-tosample discrimination task in which animals matched combinations of eight geometric shapes. Animals were trained on this task in an isolated context until they reached a baseline level of proficiency and were then tested in the three social contexts in a random order multiple times. Two subjects (Mt and Dv) have successfully completed trials under all conditions. Results indicated that there were no significant difference in taskperformance across the three conditions (Dv x^2 (1) = 0.42, p=0.58; Mt x^2 (1) = 0.02, p=0.88). In all conditions, subjects performed significantly above chance (i.e., 39/60 trials determined by a binomial distribution). Results are contrary to previous studies thatreport low status monkeys 'play dumb' when testing in a mixed social context, possibly because other studies did not account for aggressive interference by dominants while testing. Results of this study suggest that the mere presence of a dominant individualdoes not necessarily affect performance on a cognitive task, but rather the imminence of physical aggression is the most important factor influencing testing in a social context.

Modernity Strikes Back? A Historical Perspective on the Latest Increase in Interpersonal Violence (1960-1990)

There is a plethora of criminological explanations why criminal violence increased during the three decades between the early 1960s and the early 1990s. This paper argues that most available interpretations are lacking in three respects: they lack a historical perspective that anchors the three critical decades in a wider understanding of long-term trends; they take the nation-state as their unit of analysis and disregard important commonalities across the Western world; and they pay insufficient attention to different trends in broad categories of physical violence.This paper therefore takes a macro-level and long-term perspective on violent crime, focussing on European homicide during the past 160 years. It demonstrates that the period of increase was preceded by a long-term decline and convergence of homicide rates from the 1840s to the 1950s. Also, it shows that both the decline and the increase primarily resulted from temporal variation in the likelihood of physical aggression between men in public space. It argues that explanations of these common trends need to take into account broad long-term cultural change common to Western societies. In particular, the paper suggests that shifts in culturally transmitted and institutionally embedded ideals of the conduct of life may provide an explanation for long-term change in levels of interpersonal violence.

A feasibility study for assessing building occupants' indoor air quality expectations compared to nationally recognized standards

Indoor Air Quality (IAQ) can have significant implications for health, productivity, job performance, and operating cost. Professional experience in the field of indoor air quality suggests that high expectations (better than nationally established standards) (American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE)) of workplace indoor air quality lead to increase air quality complaints. To determine whether there is a positive association between expectations and indoor air quality complaints, a one-time descriptive and analytical cross-sectional pilot study was conducted. Area Safety Liaisons (n = 330) at University of Texas Health Science Center – Houston were asked to answer a questionnaire regarding their expectations of four workplace indoor air quality indicators i.e., (temperature, relative humidity, carbon dioxide, and carbon monoxide) and if they experienced and reported indoor air quality problems. A chi-square test for independence was used to evaluate associations among the variables of interest. The response rate was 54% (n = 177). Results did not show significant associations between expectation and indoor air quality. However, a greater proportion of Area Safety Liaisons who expected indoor air quality indicators to be better than the established standard experienced greater indoor air quality problems. Similarly, a slightly higher proportion of Area Liaisons who expected indoor air quality indicators to be better than the standard reported greater indoor air quality complaints. ^ The findings indicated that a greater proportion of Area Safety Liaisons with high expectations (conditions that are beyond what is considered normal and acceptable by ASHRAE) experienced greater indoor air quality discomfort. This result suggests a positive association between high expectations and experienced and reported indoor air quality complaints. Future studies may be able to address whether the frequency of complaints and resulting investigations can be reduced through information and education about what are acceptable conditions.^

Análisis del modelo regulatorio de la seguridad y salud en la construcción en España e integración de la prevención a través del diseño

La necesidad de mejorar la eficacia preventiva del sector de la construcción en España exige profundizar en el análisis del modelo regulatorio vigente a la vez que evaluar los resultados del mismo. Considerando que la regulación española emana de la Directiva 92/57/CEE, es preciso partir de un estudio específico de dicha referencia normativa para, seguidamente, identificar tanto las diferencias y particularidades introducidas en nuestra transposición nacional como, en su caso, la coherencia de las mismas con la regulación comunitaria. Para todo ello, la memoria realizada analiza de manera discriminada las diferencias que, cada modelo regulatorio de la UE-15, introduce en las figuras y herramientas de gestión preventiva instauradas por la citada Directiva. Adicionalmente, la presente investigación evalúa los resultados que, en términos de siniestralidad laboral, costes económicos y responsabilidades legales, han arrojado los vigentes modelos de regulación del sector a nivel comunitario (UE-15) y español. Dicho análisis permite identificar, además, aquellos estados miembros de la UE-15 que, en términos comparativos, han logrado una mayor eficacia preventiva específica en el sector de la construcción y establecer, en su caso, la correspondiente correlación con el tipo de modelo regulatorio. Por otra parte, se analiza la vinculación existente entre los accidentes de trabajo en la construcción y las decisiones tomadas en la etapa de diseño (incluyendo un estudio experimental) así como, con carácter específico, las técnicas desarrolladas para integrar los aspectos preventivos en dicha etapa. Dichas técnicas, englobadas a nivel internacional bajo la denominación de Prevention Through Design (PtD), son analizadas en detalle a la vez que se prospecciona su aplicación al modelo regulatorio español. Por último, se realiza un análisis comparativo del modelo regulatorio español frente a aquellos sistemas que, a nivel internacional, han logrado mejores resultados relativos para, en base al mismo, efectuar una propuesta justificada y pormenorizada de modificación del actual modelo regulatorio de la seguridad y salud en la construcción en España. The need to improve risk prevention efficacy in construction sites in Spain requires a deeper analysis of the current regulatory model while evaluating its results. Whereas the Spanish regulation stems from Directive 92/57/EEC, it is necessary to start from a specific study of such reference, and then pass to identify both the differences and particularities introduced in national transposition and, where appropriate, its consistency with the European regulation system. Above from that, this research analyzes how each country of the EU15 has adapted the provisions in Directive 92/57/EEC and their respective regulation of the preventive management tools introduced by it. Additionally, this research evaluates the results, in terms of workplace accidents, economic costs and liabilities, produced by the current models of sector regulation both at EU-15 and Spanish level. This analysis allows to identify also those member states of the EU-15 that, in comparison, have achieved greater efficiency in specific preventive construction sector and establish, where appropriate, the corresponding correlation with the type of regulatory model. Moreover, we analyze the link between occupational accidents in the construction and the decisions taken at the design stage (including a pilot study) and, with specificity, the techniques developed to integrate the preventive aspects in the design works. Such techniques, included internationally under the name of Prevention through Design (PtD), are analyzed in detail while collating their application routes to the Spanish regulatory model. Finally, we develop a comparative analysis of the Spanish regulatory model against those systems that, worldwide, have achieved better results relating to make a justified and detailed proposal to amend the current regulatory model and health and safety in construction in Spain.

Managing team learning in a Spanish commercial bank

Purpose – The purpose of this paper is to analyze how team management affects team-learning activities. Design/methodology/approach – The authors empirically study 68 teams as they operate in the natural business context of a major Spanish bank. Quantitative research utilizing multiple regression analyses is used to test hypotheses. Findings – The leadership behaviour (consideration, initiation of structure) displayed by the team leader plays a key role in facilitating team learning. Team leader behaviour characterised by consideration and in particular by initiation of structure are both positively related to team-learning activities. Cross-training of team members also contributes to team-learning behaviour. Research limitations/implications – A specific setting may limit the generalizability of findings. Further research may accordingly investigate to what extent these results can be generalized to other settings or other aspects of team learning. Practical implications – The leadership style adopted by the team leader, as well as cross-training of members, affect team-learning activities. These results link leadership theory to collective learning in teams and organizations, and suggest ways leaders can contribute to improved learning. Originality/value – The study provides new insight into how management of teams facilitates team-learning activities. While consideration is somewhat related to team learning, initiation of structure as well as cross-training appear as key variables.

La Ordenación del Territorio en las Ciudades Globales Europeas: El caso de Madrid

En la Comunidad de Madrid el modelo de ocupación del territorio en las dos últimas décadas ha obedecido a factores de oferta del mercado y no a las necesidades de la población, ello provoca un consumo de suelo y de recursos que conducen a una sobrexplotación insostenible. Las metrópolis globales están experimentando rápidas e intensas transformaciones, basadas en los paradigmas emergentes de la globalización, la gobernanza, la metropolizacion y la dispersión de las actividades en el territorio y a través de ellos se abordan los planes de Londres, París y las tentativas de Madrid. La globalización provoca la pérdida de soberanía de las administraciones publicas y la competitividad entre las ciudades globales en Europa, Londres, Paris y Madrid, son centros de poder, de concentración y crecimiento donde se produce la dualización del espacio y donde la desigualdad participa de la restructuración urbana, concentración de pobreza frente a espacios de la nueva clase emergente en donde dominan los sectores de servicios y las tecnologías de la información. Frente al desarrollo urbano neoliberal de regulación a través del mercado y basada en criterios de eficiencia de la Nueva Gestión Pública, se vislumbra la posibilidad de que la sociedad se administre a si misma por medio de acciones voluntarias y responsables que promuevan los intereses colectivos mediante el reconocimiento de su propia identidad, introduciendo el concepto de gobernanza. Frente, a la explotación del territorio por parte de la sociedad extractiva que genera corrupcion, se propone un modelo de cooperación público-privada basado en la confianza mutua, un marco regulador estable, la transparencia y la información a cuyo flujo más homogéneo contribuirán sin duda las TICs. En todo este proceso, las regiones metropolitanas en Europa se erigen como motores del crecimiento, donde los límites administrativos son superados, en un territorio cada vez más extendido y donde los gobiernos locales tienen que organizarse mediante un proceso de cooperación en la provisión de servicios que ayuden a evitar los desequilibrios territoriales. El fenómeno de la dispersión urbana en desarrollos de baja densidad, los centros comerciales periféricos, la expulsión hacia la periferia de las actividades de menor valor añadido y la concentración de funciones directivas en el centro, conducen a una fragmentación del territorio en islas dependientes del automóvil y a procesos de exclusión social por la huida de las rentas altas y la expulsión de las rentas bajas de los centros urbanos. Se crean fragmentos monofuncionales y discontinuos, apoyados en las autovías, lugares carentes de identidad y generadores de despilfarro de recursos y una falta de sostenibilidad ambiental, económica y social. El estudio de la cultura de la planificación en Europa ayuda a comprender los diferentes enfoques en la ordenación del territorio y el proceso de convergencia entre las diferentes regiones. Los documentos de la UE se basan en la necesidad de la competitividad para el crecimiento europeo y la cohesión social y en relación al territorio en los desarrollos policéntricos, la resolución del dualismo campo-ciudad, el acceso equilibrado a las infraestructuras, la gestión prudente de la naturaleza, el patrimonio y el fomento de la identidad. Se proponen dos niveles de estudio uno actual, los últimos planes de Londres y Paris y el otro la evolución de las tentativas de planes en la Región madrileña siempre en relación a los paradigmas emergentes señalados y su reflejo en los documentos. El Plan de Londres es estratégico, con una visión a largo plazo, donde se confiere un gran interés al proceso, al papel del alcalde como líder y su adaptación a las circunstancias cambiantes, sujeto a las incertidumbres de una ciudad global. El desarrollo del mismo se concibe a través de la colaboración y cooperación entre las administraciones y actores. La estructura del documento es flexible, establece orientaciones y guías indicativas, para la redacción de los planes locales, no siendo las mismas vinculantes y con escasa representación grafica. El Plan de París es más un plan físico, similar al de otros centros europeos, trabaja sobre los sectores y sobre los territorios, con información extensa, con características de “Plan Latino” por la fuerza de la expresión gráfica, pero al mismo tiempo contiene una visión estratégica. Es vinculante en sus determinaciones y normativas, se plantea fomentar, pero también prohibir. Ambos planes tratan la competitividad internacional de sus centros urbanos, la igualdad social, la inclusión de todos los grupos sociales y la vivienda como una cuestión de dignidad humana. Londres plantea la gobernanza como cooperación entre sector público-privado y la necesaria cooperación con las regiones limítrofes, en París las relaciones están más institucionalizadas resaltando la colaboración vertical entre administraciones. Ambos plantean la densificación de nodos servidos por transporte público, modos blandos y el uso los TODs y la preservación de la infraestructura verde jerarquizada, la potenciación de la red azul y la mejora del paisaje de las periferias. En las “tentativas” de planes territoriales de Madrid se constata que estuvieron sujetas a los ciclos económicos. El primer Documento las DOT del año 1984, no planteaba crecimiento, ni económico ni demográfico, a medio plazo y por ello no proponía una modificación del modelo radio concéntrico. Se trataba de un Plan rígido volcado en la recuperación del medio rural, de la ciudad, el dimensionamiento de los crecimientos en función de las dotaciones e infraestructuras existentes. Aboga por la intervención de la administración pública y la promoción del pequeño comercio. Destaca el desequilibrio social en función de la renta, la marginación de determinados grupos sociales, el desequilibrio residencia/empleo y la excesiva densidad. Incide en la necesidad de viviendas para los más desfavorecidos mediante el alquiler, la promoción suelo público y la promoción del ferrocarril para dar accesibilidad al espacio central. Aboga por el equipamiento de proximidad y de pequeño tamaño, el tratamiento paisajístico de los límites urbanos de los núcleos y el control de las actividades ilegales señalando orientaciones para el planeamiento urbano. Las Estrategias (1989) contienen una visión: la modificación del modelo territorial, mediante la intervención pública a través de proyectos. Plantea la reestructuración económica del territorio, la reconversión del aparato productivo, la deslocalización de actividades de escaso valor añadido y una mayor ubicuidad de la actividad económica. Incide en la difusión de la centralidad hacia el territorio del sur, equilibrándolo con el norte, tratando de recomponer empleo y residencia, integrando al desarrollo económico las periferias entre sí y con el centro. Las actuaciones de transporte consolidarían las actuaciones, modificando el modelo radio concéntrico facilitando la movilidad mediante la red de cercanías y la intermodalidad. El plan se basaba en el liderazgo del Consejero, no integrando sectores como el medio ambiente, ni estableciendo un documento de seguimiento de las actuaciones que evaluara los efectos de las políticas y su aportación al equilibrio territorial, a través de los proyectos realizados. El Documento Preparatorio de las Bases (1995), es más de un compendio o plan de planes, recoge análisis y propuestas de los documentos anteriores y de planes sectoriales de otros departamentos. Presenta una doble estructura: un plan físico integrador clásico, que abarca los sectores y territorios, y recoge las Estrategias previas añadiendo puntos fuertes, como el malestar urbano y la rehabilitación el centro. Plantea la consecución del equilibrio ambiental mediante el crecimiento de las ciudades existentes, la vertebración territorial basada en la movilidad y en la potenciación de nuevas centralidades, la mejora de la habitabilidad y rehabilitación integral del Centro Urbano de Madrid, y la modernización del tejido productivo existente. No existe una idea-fuerza que aglutine todo el documento, parte del reconocimiento de un modelo existente concentrado y congestivo, un centro urbano dual y dos periferias al este y sur con un declive urbano y obsolescencia productiva y al oeste y norte con una dispersión que amenaza al equilibrio medioambiental. Señala como aspectos relevantes, la creciente polarización y segregación social, la deslocalización industrial, la aparición de las actividades de servicios a las empresas instaladas en las áreas metropolitanas, y la dispersión de las actividades económicas en el territorio por la banalización del uso del automóvil. Se plantea el reto de hacer ciudad de la extensión suburbana y su conexión con el sistema metropolitano, mediante una red de ciudades integrada y complementaria, en búsqueda de un mayor equilibrio y solidaridad territorial. Las Bases del PRET (1997) tenían como propósito iniciar el proceso de concertación en que debe basarse la elaboración del Plan. Parte de la ciudad mediterránea compacta, y diversa, y de la necesidad de que las actividades económicas, los servicios y la residencia estén en proximidad, resolviéndolo mediante una potente red de transporte público que permitiese una accesibilidad integrada al territorio. El flujo de residencia hacia la periferia, con un modelo ajeno de vivienda unifamiliar y la concentración del empleo en el centro producen desequilibrio territorial. Madrid manifiesta siempre apostó por la densificación del espacio central urbanizado, produciendo su congestión, frente al desarrollo de nuevos suelos que permitieran su expansión territorial. Precisa que es necesario preservar los valores de centralidad de Madrid, como generador de riqueza, canalizando toda aquella demanda de centralidad, hacia espacios más periféricos. El problema de la vivienda no lo ve solo como social, sino como económico, debido a la pérdida de empleos que supone su paralización. Observa ya los crecimientos residenciales en el borde de la region por el menor valor del suelo. Plantea como la política de oferta ha dado lugar a un modelo de crecimiento fragmentado, desequilibrado, desestructurado, con fuertes déficits dotacionales y de equipamiento, que inciden en la segregación espacial de las rentas, agravando el proceso de falta de identidad morfológica y de desarraigo de los valores urbanos. El plan señalaba que la presión sobre el territorio creaba su densificación por las limitaciones de espacio, Incidía en limitar el peso de la intervención pública, no planteando propuestas de cooperación público-privado. La mayor incoherencia estriba en que los objetivos eran innovadores y coinciden en su mayoría con las propuestas estudiadas de Londres o Paris, pero se intentan implementar a través de un cambio hacia un modelo reticulado homogéneo, expansivo sobre el territorio, que supone un consumo de suelo y de infraestructuras para solucionar un problema inexistente, la gestión de la densidad. Durante las dos últimas décadas en ausencia de un plan regional, la postura neoliberal fue la de un exclusivo control de legalidad del planeamiento, los municipios entraron en un proceso de competencia para aprovechar las iniciales ventajas económicas de los crecimientos detectados, que proporcionaban una base económica “sólida” a unos municipios con escasos recursos en sus presupuestos municipales. La legislación se modifica a requerimiento de grupos interesados, no existiendo un marco estable. Se pierde la figura del plan no solo a nivel regional, si no en los sectores y el planeamiento municipal donde los municipios tiende a basarse en modificaciones puntuales con la subsiguiente pérdida del modelo urbanístico. La protección ambiental se estructura mediante un extenso nivel de figuras, con diversidad de competencias que impide su efectiva protección y control. Este proceso produce un despilfarro en la ocupación del suelo, apoyada en las infraestructuras viarias, y un crecimiento disperso y de baja densidad, cada vez más periférico, produciéndose una segmentación social por dualización del espacio en función de niveles de renta. Al amparo del boom inmobiliario, se produce una falta de política social de vivienda pública, más basada en la dinamización del mercado con producción de viviendas para rentas medias que en políticas de alquiler para determinados grupos concentrándose estas en los barrios desfavorecidos y en la periferia sur. Se produce un incremento de la vivienda unifamiliar, muchas veces amparada en políticas públicas, la misma se localiza en el oeste principalmente, en espacios de valor como el entorno del Guadarrama o con viviendas más baratas por la popularización de la tipología en la frontera de la Región. El territorio se especializa a modo de islas monofuncionales, las actividades financieras y de servicios avanzados a las empresas se localizan en el norte y oeste próximo, se pierde actividad industrial que se dispersa más al sur, muchas veces fuera de la región. Se incrementan los grandes centros comerciales colgados de las autovías y sin población en su entorno. Todo este proceso ha provocado una pérdida de utilización del transporte público y un aumento significativo del uso del vehículo privado. En la dos últimas décadas se ha producido en la región de Madrid desequilibrio territorial y segmentación social, falta de implicación de la sociedad en el territorio, dispersión del crecimiento y un incremento de los costes ambientales, sociales y económicos, situación, que solo, a través del uso racional del territorio se puede reconducir, apoyado en una planificación integrada sensible y participativa. ABSTRACT In Madrid the model of land occupation in the past two decades has been driven by market supply factors rather than the needs of the population. This results in a consumption of land and resources that leads to unsustainable overexploitation. Addressing this issue must be done through sensitive and participatory integrated planning. Global cities are experiencing rapid and intense change based on the emerging paradigms of globalization, governance, metropolization and the dispersion of activities in the territory. Through this context, a closer look will be taken at the London and Paris plans as well as the tentative plans of Madrid. Globalization causes the loss of state sovereignty and the competitiveness among global cities in Europe; London, Paris and Madrid. These are centres of power, concentration and growth where the duality of space is produced, and where inequality plays a part in urban restructuration. There are concentrated areas of poverty versus areas with a new emerging class where the services sector and information technologies are dominant. The introduction of ICTs contributes to a more homogeneous flow of information leading, us to the concept of governance. Against neoliberal urban development based on free market regulations and efficiency criteria as established by the “New Public Management”, emerge new ways where society administers itself through voluntary and responsible actions to promote collective interests by recognizing their own identity. A new model of public-private partnerships surfaces that is based on mutual trust, transparency, information and a stable regulatory framework in light of territorial exploitation by the “extractive society” that generates corruption. Throughout this process, European metropolitan regions become motors of growth where administrative boundaries are overcome in an ever expanding territory where government is organized through cooperative processes to provide services that protect against regional imbalances. Urban sprawl or low-density development as seen in peripheral shopping centres, the off-shoring of low added-value activities to the periphery, and the concentration of business and top management functions in the centre, leads to a fragmentation of the territory in automobile dependent islands and a process of social exclusion brought on by the disappearance of high incomes. Another effect is the elimination of low income populations from urban centres. In consequence, discontinuous expansions and mono-functional places that lack identity materialize supported by a highway network and high resource consumption. Studying the culture of urban planning in Europe provides better insight into different approaches to spatial planning and the process of convergence between different regions. EU documents are based on the need of competitiveness for European growth and social cohesion. In relation to polycentric development territory they are based on a necessity to solve the dualism between field and city, balanced access to infrastructures, prudent management of nature and solidifying heritage and identity Two levels of study unfold, the first being the current plans of London and Île-de-France and the second being the evolution of tentative plans for the Madrid region as related to emerging paradigms and how this is reflected in documents. The London Plan is strategic with a long-term vision that focuses on operation, the role of the mayor as a pivotal leader, and the adaptability to changing circumstances brought on by the uncertainties of a global city. Its development is conceived through collaboration and cooperation between governments and stakeholders. The document structure is flexible, providing guidance and indicative guidelines on how to draft local plans so they are not binding, and it contains scarce graphic representation. The Plan of Paris takes on a more physical form and is similar to plans of other European centres. It emphasizes sectors and territories, using extensive information, and is more characteristic of a “Latin Plan” as seen in its detailed graphic expression. However, it also contains a strategic vision. Binding in its determinations and policy, it proposes advancement but also prohibition. Both plans address the international competitiveness of urban centres, social equality, inclusion of all social groups and housing as issues of human dignity. London raises governance and cooperation between public and private sector and the need for cooperation with neighbouring regions. In Paris, the relations are more institutionalized highlighting vertical collaboration between administrations. Both propose nodes of densification served by public transportation, soft modes and the use of TOD, the preservation of a hierarchical green infrastructure, and enhancing the landscape in urban peripheries. The tentative territorial plans for the Madrid region provide evidence that they were subject to economic cycles. The first document of master guidelines (1984) does not address either economic or demographic growth in the mid term and therefore does not propose the modification of the radio-concentric model. It is a rigid plan focused on rural and urban recovery and the dimensioning of growth that depends on endowments and infrastructures. It advocates government intervention and promotes small business. The plan emphasizes social imbalance in terms of income, marginalization of certain social groups, the imbalance of residence/employment and excessive density. It stresses the need for social rent housing for the underprivileged, promotes public land, and the supports rail accessibility to the central area. It backs facilities of proximity and small size, enhancing the landscaping of city borders, controlling illegal activities and draws out guidelines for urban planning. The strategies (1989) contain a vision: Changing the territorial model through public intervention by means of projects. They bring to light economic restructuring of territory, the reconversion of the productive apparatus, relocation of low value-added activities, and greater ubiquity of economic activity. They also propose the diffusion of centrality towards southern territories, balancing it with the north in an attempt to reset employment and residence that integrates peripheral economic development both in the periphery and the centre. Transport would consolidate the project, changing the radius-concentric model and facilitating mobility through a commuter and inter-modality network. The plan derives itself from the leadership of the minister and does not integrate sectors such as environment. It also does not incorporate the existence of a written document that monitors performance to evaluate the effects of policies and their contribution to the territorial balance. The Preparatory Document of the Bases, (1995) is more a compendium, or plan of plans, that compiles analysis and proposals from previous documents and sectorial plans from other departments. It has a dual structure: An integrating physical plan covering the sectors and territories that includes the previous strategies while adding some strengths. One such point is the urban discomfort and the rehabilitation of the centre. It also poses the achievement of environmental balance through the growth of existing cities, the territorial linking based on mobility, strengthening new centres, improving the liveability and comprehensive rehabilitation of downtown Madrid, and the modernization of the existing production network. There is no one powerful idea that binds this document. This is due to the recognition of an existing concentrate and congestive model, a dual urban centre, two eastern and southern suburbs suffering from urban decay, and an obsolescent productive north and west whose dispersion threatens the environmental balance. Relevant aspects the document highlights are increasing polarization and social segregation, industrial relocation, the emergence of service activities to centralized companies in metropolitan areas and the dispersion of economic activities in the territory by the trivialization of car use. It proposes making the city from the suburban sprawl and its connection to the metropolitan system through a network of integrated and complementary cities in search of a better balance and territorial solidarity. The Bases of PRET (1997) aims to start the consultation process that must underpin the development of the plan. It stems from a compact and diverse Mediterranean city along with the need for economic activities, services and residences that are close. To resolve the issue, it presents a powerful network of public transport that allows integrated accessibility to the territory. The flow of residence to the periphery based on a foreign model of detached housing and an employment concentration in the centre produces territorial imbalance. Madrid always opted for the densification of the central space, producing its congestion, against the development of new land that would allow its territorial expansion. The document states that the necessity to preserve the values of the housing problem is not only viewed as social, but also economic due to the loss of jobs resulting from their paralysis. It notes the residential growth in the regional border due to the low price of land and argues that the policy of supply has led to a fragmented model of growth that is unbalanced, unstructured, with strong infrastructure and facility deficits that affect the spatial segregation of income and aggravate the lack of morphological identity, uprooting urban values. The pressure on the territory caused its densification due to space limitation; the proposed grid model causes land consumption and infrastructure to solve a non-problem, density. Focusing on limiting the weight of public intervention, it does not raise proposals for public-private cooperation. The biggest discrepancy is that the targets were innovative and mostly align with the proposals in London and Paris. However, it proposes to be implemented through a shift towards a uniform gridded model that is expansive over territory. During the last two decades, due to the absence of a regional plan, a neoliberal stance held exclusive control of the legality of urban planning. The municipalities entered a competition process to take advantage of initial economic benefits of such growth. This provided a “solid” economic base for some municipalities with limited resources in their municipal budgets. The law was amended without a legal stable framework at the request of stakeholders. The character of the plan is lost not only regionally, but also in the sectors and municipal planning. This tends to be based on specific changes with the loss of an urban model. Environmental protection is organized through an extensive number of protection figures with diverse competencies that prevent its effective protection. This process squanders the use of the land, backed by increasing road infrastructure, dispersed occupations with low-density growth causing a social segmentation due to space duality based on income levels. During the housing boom, there is a reduction in social public housing policy mostly due to a boost in the market of housing production for average incomes than in rental policies for needy social groups that focus on disadvantaged neighbourhoods and southern suburbs. As a result, there is an increase in single-family housing, often protected by public policy. This is located primarily in the west in areas of high environmental value such as Guadarrama. There is also cheaper housing due to the popularization of typology in the border region. There, territory works as a mono-functional islands. Financial activities and advanced services for companies are located to the north and west where industrial activity is lost as it migrates south, often outside the region. The number of large shopping centres hanging off the highway infrastructure with little to no surrounding population increases. This process leads to the loss of dependency on public transport and a significant increase in the use of private vehicles. The absence of regional planning has produced more imbalance, more social segmentation, more dispersed growth and a lot of environmental, social and economic costs that can only be redirected through rational territorial.

AS RELAÇÕES ENTRE GESTÃO DA DIVERSIDADE E CULTURA ORGANIZACIONAL EM UMA EMPRESA DO SETOR PORTUÁRIO DO RIO DE JANEIRO

A cultura de uma organização é importante para que seus colaboradores possuam mesmos objetivos e valores. Porém, em busca de manter uma estratégia competitiva e agir de forma responsável na comunidade em que se encontra, a empresa precisa inovar e adaptar-se. A gestão da diversidade apresenta-se como uma válida forma de enfrentar estes novos desafios e exigências. Contudo, há muitos obstáculos para que uma gestão da diversidade seja bem-sucedida. Este estudo propõe-se em entender como a diversidade pode afetar a cultura de uma organização. Além disso, como a cultura pode afetar a estratégia de gestão da diversidade. Foi utilizado para este objetivo um estudo de caso em profundidade com seis entrevistas. As entrevistas foram apoiadas em um roteiro semi estruturado. A análise dos dados obtidos foi feita pela análise de conteúdo. De acordo com a pesquisa realizada, sugere que a cultura organizacional e a gestão da diversidade estão diretamente conectadas e que podem influenciar positivamente uma a outra, porém precisam manter um equilíbrio em suas ações para que não causem prejuízos à organização.

Automação portuária e segurança do trabalho.

Este trabalho objetiva contribuir ao estudo da automação portuária e sua influência na evolução dos acidentes do trabalho. A automação - sobrepondo-se à mecanização - desloca o homem no trabalho e do trabalho. Na contextualização fundamentam-se em retrospectiva e perspectiva aspectos do trabalho humano, da automação e fatores que configuram a atual complexidade do meio ambiente do trabalho portuário. A análise relaciona ocorrências aos processos de movimentação em porto das principais modalidades de cargas: granéis sólidos, granéis líquidos, contêineres e carga geral, apresentados na proposta METARAP - Metodologia de uso da Automação para a Redução de Acidentes Portuários. Para quantificar e permitir uma discussão sustentada utilizou-se dados de atividades dos TPAs -Trabalhadores Portuários Avulsos no Porto de Santos, no período 2009-2014, no qual foram aplicados mais de 30 milhões de homens hora de trabalho. Pelo conhecimento dos acidentes ocorridos, constatou-se redução de 53,97% na taxa de frequência e de 39,45% na taxa de gravidade, calculados por milhão de horas de exposição ao risco. São fatores referenciais da efetividade das ações desenvolvidas nesse sítio. Discute-se a importância da Segurança do Trabalho; o Meio Ambiente do Trabalho num contexto de progressiva automação de processos de produção; a importância de novas tecnologias e potencial para alcançar e consolidar sistemas ultra seguros em terminais e portos; e a ação efetiva da gestão e equipes de segurança do trabalho e da conscientização do trabalhador. Adicionalmente indicamse possibilidades de continuidade dos estudos.

Leading Safety Indicators: Proactively Monitoring Safety Performance

Traditional measures or indicators of workplace safety performance reflect unrecognized hazards, unsafe conditions, reckless behavior, and other safety program shortcomings only after a worker is injured or falls ill. In contrast to traditional or lagging indicators, leading indicators can predict poor safety performance to ensure that safety program failings are addressed before an occupational injury or illness actually occurs. This Capstone Project identified a variety of proactive safety management practices, policies, and activities shown to have a positive impact on workplace safety as leading safety indicators. The end result is a comprehensive framework of leading safety indicators that employers can use to proactively gauge safety program performance and address unrecognized hazards, unsafe conditions, reckless behavior, and other safety program deficiencies.
