We use a structural equation model with categorical observed variables. We get that participation in microcredit programmes has a positive impact on both the empowerment's dimensions considered, while partner's attitudes effect is weaker, proving that gender community norms are likely to be rooted in women's minds regardless of the partners' perceptions of women's status.

Empirical evidence highlights two main features of regional development. A generally lagging periphery with high growth rates on the one hand and a set of leading regions facing the challenge of global competitiveness on the other. There is evidence that CP support advanced economic development in lagging and peripheral regions, hence contributing to the "convergence objective". Nonetheless, effective catch-up remains circumscribed to certain very few regions. Contrarily, CP support has failed to stimulate growth potential in leading regions, failing to strengthen EU competitiveness. Evidence presented in this paper provide useful insights for the current debate about the reshaping of EU cohesion policy toward a more place-based approach.

A well known model in this field is the Fay-Herriot model, in which unobservable parameters are assumed Gaus- sian. In Hierarchical models assumptions about unobservable quantities are dicult to check. Sinharay and Stern (2003) for a special case of the Fay-Herriot model, showed that violations of

Design/methodology/approach -First, the paper investigates the determinants of unemployment outflows in these two Mediterranean labour markets. Then, the paper examines discrepancies and similarities between specific outflow determinants, especially the interactions between gender and marital status, by comparing results obtained across countries. Findings -The findings of the paper suggest that gender and marital status influence the probability of unemployment outflows in both countries, although not in the same way, especially with reference to marital status. Discrepancies also emerge in relation to the role of geographical area of residence. Originality/value -International comparisons of unemployment outflows are rather new in the literature, and as far as we know none have been performed using European Union Statistics on Income and Living Conditions data. Further, although studies quite often examine the issue of gender-related labour mobility using the European Community Household Panel survey that took place in the 1990s ), one of the main contributions of this paper is that it provides a systematic examination of the issue, considering the influence of gender and marital status differences on patterns of unemployment outflows to employment and inactivity.

Among the many methods proposed in the literature to eliminate the confounding effect of changing weather conditions, we employ a stratification of daily maxima based on regression trees. Within each stratum conditional independence and Weilbull distribution are assumed for maxima. Long-term trend is defined non-parametrically by the sequence of yearly medians. Models are estimated following the Bayesian approach. The alternative assumptions of common and stratum specific trends are compared and a model with common trend for all strata is selected for the analyzed real dataset. The conditional independence assumption is checked by the comparison with a model including an autoregressive component.

These skills include two different abilities, assertiveness and responsiveness. This study investigated the development of these abilities in early implanted children and their relationships with lexical development and some language-sensitive variables. Prospective, observational, nonrandomized study. Participants included 28 children with congenital profound sensorineural hearing loss. The mean age at device activation was 13.3 months (standard deviation [SD] ±4.2). The Social-Conversational Skills Rating Scale was used to evaluate assertiveness and responsiveness. The MacArthur-Bates Communicative Development Inventory (Words and Sentences form) was used to analyze the lexical development. The device experience was 12 months for each child, and the mean age at testing was 25.9 months (SD ±4.6). Assertiveness and responsiveness scores were within the normal range of normal-hearing age-matched peers. Age at cochlear implant activation exerted a significant impact, with the highest scores associated to the youngest patients. The residual correlations between assertiveness and responsiveness with the lexical development were positive and strongly significant (r = 0.69 and 0.73, respectively). Preoperative hearing threshold demonstrated an associated significant coefficient on the assertiveness score. Age at diagnosis and maternal education level were not correlated with the social conversational skills. Early-implanted children developed social conversational skills that are similar to normal-hearing peers matched for age 1 year after device activation. Social conversational skills and lexical development were strongly correlated, but the present study design cannot specify the direction of this relationship. Children with better preoperative residual hearing exhibited better assertive ability. 4 Laryngoscope, 2015.
