Nós dizemos que eles são como nós precisamos que eles sejam para nos podermos ver como nos vemos. Vicissitudes identitárias nas relações inter-étnicas

Como Calhoun (1996) e Mennell (1996) referem, apesar da atenção acrescida dada às construções, estratégias e políticas da identidade, permanece uma evidente dificuldade de articulação entre diferentes corpora e, nomeadamente, daqueles que derivam da utilização de um nível micro de observação e análise e de um nível de macro-focalização. (í^om base num estudo de caso, tentaremos evidenciar que (a) os processos identitários articulam as duas dimensões de análise e que (b) o nível micro- familiar constitui o referente e o mediador simbôlico-identitário adequado da articulação entre as micro e as macro-perspectivas,^ (c) a partir do qual emerge toda uma gama de idiomas simbólicos (familialistas, instrumentais e morais). O papel desempenhado pela experiência arcaica familiar tem a ver com o facto de que é nesse nível que se cruzam os gêneros e as gerações, se negoceia e gere a dimensão identitária da sexualidade, a moral e a construção diferenciada de identidades categoriais, e são organizadas as primeiras fronteiras entre «nós» e «eles»^, ao mesmo tempo que se vai diferenciando a identidade pessoal, sob a forma da construção do «indivíduo» que será progressivamente confrontado com a transposição projectiva do(s) poder(es) intra-familiar(es) para o nível macro do poder transcendental e dos poderes de Estado.

Das inter-etnicidades em processos de inserção social diferenciadas às dinâmicas do sistema-mundo: uma abordagem estrutural-dinâmica

Em pesquisas anteriores, procurámos mostrar que (i) as representações identitárias possuem uma estrutura multidimensional, cujos níveis (pessoal, bio-cultural, sócio-histórico / político, ideal, «moral», etc.) estão inter-relacionados, e formam um sistema identitário pessoal, se bem que partilhado, em proporções variáveis, com os outros emissores identitários inseridos na mesma categoria sócio-histórica; (ii) sistema identitário esse detentor de potencialidades estratégicas (Kastersztein, 1990) - ideológicas, simbólicas e fantasmáticas -, derivadas da articulação inconsciente entre os diferentes níveis mobilizados. Tentámos evidenciar ainda, no nível mais abrangente das representações identitárias dos grupos sócio-históricos, (iii) como o grau de sobreposição e convergência das atribuições identitárias, tanto ao grupo.de identificação como aos grupos de comparação interactiva, é parcial, indiciando estratégias de maior ou menor distanciação / aproximação identitária inter-nacional ou inter-étnica; (iv) e como, no seu conjunto, as representações identitárias apresentam uma lógica e uma economia retórica, tendenciosa e performativa (pro domo sua), criando para os sujeitos, no interior dos seus grupos, e para os seus grupos identitários, na comparação com os outros, uma imagem de primo inter pares, na medida em que constroiem como «real» o «real identitariamente conveniente» e não aquele que «objectivamente » é «objectivado» (em termos de poder tecnológico, econômico ou militar).

Directed Giving: Evidence from an Inter-Household Transfer Experiment*

We investigate the determinants of giving in a lab-in-the-field experiment with large stakes. Study participants in urban Mozambique play dictator games where their counterpart is the closest person to them outside their household. Dictators share more with counterparts when they have the option of giving in kind (in the form of goods), compared to giving that must be in cash. Qualitative post-experiment responses suggest that this effect is driven by a desire to control how recipients use gifted resources. Standard economic determinants such as the rate of return to giving and the size of the endowment also affect giving, but the effects of even large changes in these determinants are significantly smaller than the effect of the in-kind option. Our results support theories of giving where the utility of givers depends on the composition (not just the level) of gift-recipient expenditures, and givers thus seek control over transferred resources.

Developing and validating a measure of the strength of the HRM system: Operationalizing the construct and relationships among its dimensions

The four studies in this article introduce a questionnaire to measure Strength of the HRM System (HRMSQ), a multidimensional construct, theoretically developed by Bowen and Ostroff (2004). Strength of the HRM System is a set of process characteristics that lead to effectiveness in conveying signals to employees that allow them to create a shared meaning of desired and appropriate work behaviours. Nine characteristics are suggested, grouped in three features: Distinctiveness, Consistency and Consensus. Study 1 developed and tested a questionnaire in a sample of workers from five different sectors. Study 2 cross-validated the measure in a sample of civil servants in a municipality. These two studies used performance appraisal as the reference HRM practice and led to a short version of the HRMSQ. Study 3 and Study 4 extend the HRMSQ to several common HRM practices. The HRMSQ is tested in two samples, of call center and several private and public organizations‟ workers (study 3). In study 4 the questionnaire is refined and tested with a sample from a hotel chain and finally cross-validated with two other samples, in the insurance and batteries sectors, leading to a longer version of the HRMSQ. Content analysis of several interviews with human resource managers and the Rasch model (1960, 1961, 1980), were used to define and select the indicators of the questionnaire. Convergent, discriminant and predictive validity of the measure are tested. The results of the four studies highlight the complexity of the relationships between the proposed characteristics and support the validity of a parsimonious measure of Strength of the HRM System.

Influence of Lean and Green on supply chain performance: an interpretive structural modelling model

This work aims to identify and rank a set of Lean and Green practices and supply chain performance measures on which managers should focus to achieve competitiveness and improve the performance of automotive supply chains. The identification of the contextual relationships among the suggested practices and measures, was performed through literature review. Their ranking was done by interviews with professionals from the automotive industry and academics with wide knowledge on the subject. The methodology of interpretive structural modelling (ISM) is a useful methodology to identify inter relationships among Lean and Green practices and supply chain performance measures and to support the evaluation of automotive supply chain performance. Using the ISM methodology, the variables under study were clustered according to their driving power and dependence power. The ISM methodology was proposed to be used in this work. The model intends to provide a better understanding of the variables that have more influence (driving variables), the others and those which are most influenced (dependent variables) by others. The information provided by this model is strategic for managers who can use it to identify which variables they should focus on in order to have competitive supply chains.
