Evaluating the causal economic impacts of transport investments: evidence from the Madrid–Barcelona high speed rail corridor

This paper evaluates economic impacts arising from the introduction of high-speed rail (HSR) between Madrid and Barcelona. Using difference-in-differences estimation we estimate an average treatment effect for provinces with stops on the HSR line of 2.4% for economic output, 3.3% for numbers of firms, and 1.1% for labour productivity. We complement our DID results with a synthetic control analysis for Lleida and Tarragona, two provinces that we argue were assigned HSR stations largely due to their incidental location. We find that both the number of firms and labour productivity are substantially higher in these provinces than in their synthetic counterparts.     

Women’s Movements in Portugal and Spain: Democratic Processes and Policy Outcomes

Portugal and Spain underwent dramatic transformations between 1974 and the early 1980s, transitioning from dictatorships to democracies. In this article I explore why Portugal was faster than Spain in adopting key gender-rights policies (e.g., divorce, equal pay, state feminism) during the period in question. Bridging insights from the democratization, social movement, and women’s studies literatures, I argue that Portugal’s accelerated policy path on women’s rights can be explained by three complex factors: (1) the nature of the revolutionary transition, which structured options for women’s movements and for institutional actors; (2) the configuration of movement-party alliances; and (3) supranational pressures to reorganize the state-civil society relationship. The study contributes to the engendering of democratization processes in Iberia by paying close attention to the interconnected agency of women’s movements with other political actors at a time of regime transformation.     

Agricultural policies and development: A socioeconomic investigation applied to Sri Lanka

This paper explores the interrelationship between agricultural policies and development by means of a dynamically recursive, computable general equilibrium model applied to Sri Lanka. The agricultural policies investigated include elimination of the food subsidy, land reform, and technical change in agriculture. The goals considered are the levels and growth rates of GNP and employment, the distribution of income, and the real income level of the lowest income group. The study provides a quantitative assessment of the association between policies and goals and identifies the key economic mechanisms in this association.     

Distance-based approach in univariate longitudinal data analysis

In this paper, we propose a methodology to analyze longitudinal data through distances between pairs of observations (or individuals) with regard to the explanatory variables used to fit continuous response variables. Restricted maximum-likelihood and generalized least squares are used to estimate the parameters in the model. We applied this new approach to study the effect of gender and exposure on the deviant behavior variable with respect to tolerance for a group of youths studied over a period of 5 years. Were performed simulations where we compared our distance-based method with classic longitudinal analysis with both AR(1) and compound symmetry correlation structures. We compared them under Akaike and Bayesian information criterions, and the relative efficiency of the generalized variance of the errors of each model. We found small gains in the proposed model fit with regard to the classical methodology, particularly in small samples, regardless of variance, correlation, autocorrelation structure and number of time measurements.     

Racial/Ethnic Minority Community College Students' Critical Consciousness and Social Cognitive Career Outcomes

A need exists to better understand how racial/ethnic minority students' critical consciousness development in response to marginalization may be involved in their educational and career development. We therefore examined the link between critical consciousness development and career decision self-efficacy and career outcome expectations among racial/ethnic minority community college students. Following social cognitive career theory's conceptual pillars, we developed a testable model integrating critical consciousness and social cognitive variables. This model was tested with 135 racially and ethnically diverse community college students. Data analysis included path analyses and tests of model fit using structural equation modeling. Results suggested that (a) higher critical agency is linked to higher career decision self-efficacy and outcome expectations and (b) critical action and reflection have a bidirectional link and predict higher critical agency. Implications for research and practice aiming to close educational and career gaps among racial/ethnic minorities are discussed.     

A distance-based model for spatial prediction using radial basis functions

In the context of local interpolators, radial basis functions (RBFs) are known to reduce the computational time by using a subset of the data for prediction purposes. In this paper, we propose a new distance-based spatial RBFs method which allows modeling spatial continuous random variables. The trend is incorporated into a RBF according to a detrending procedure with mixed variables, among which we may have categorical variables. In order to evaluate the efficiency of the proposed method, a simulation study is carried out for a variety of practical scenarios for five distinct RBFs, incorporating principal coordinates. Finally, the proposed method is illustrated with an application of prediction of calcium concentration measured at a depth of 0–20 cm in Brazil, selecting the smoothing parameter by cross-validation.     

On intra-annual consumption-poverty in the U.S: Response to SNAP and the importance of within-year variation

We use U.S. quarterly consumption data and decomposable poverty indexes to study consumption-based intra-annual poverty and its relationship to participation in the Supplemental Nutrition Assistance Program (SNAP). Intra-annual spells of consumption-poverty account for half of the incidence and one-third of the severity of all consumption-poverty among U.S. households. Households experiencing consumption-poverty for at least one quarter, but not for the whole year, are more likely to self-select into SNAP than the general population but less likely to do so than those who are poor for the year. SNAP participation, in turn, reduces annual and intra-annual poverty.     

How leader humility helps teams to be humbler,psychologically stronger,and more effective: A moderated mediation model

We hypothesize that (a) the level of humility expressed by leaders predicts team performance through, serially, team humility and team PsyCap, and (b) the strength (i.e., consensus within the team) of the leader humility, team humility and team PsyCap moderates the paths of that hypothesized model. A sample comprising 82 teams (82 leaders; 332 team members) was collected. Team members reported leader humility, team humility and team PsyCap. Leaders reported team performance. To handle the risks of common method bias, each mediating path of the hypothesized model is based on data from two different subsamples within each team. Our model's most novel theoretical contribution is the (moderated mediated) connection between leader humility, collective humility, and team PsyCap, and this was consistently supported in our data. Our inconsistent findings dealing with the relationship between team PsyCap and performance is well established in the literature and our results in both sub-samples were in the theorized direction. The study contributes to understand why, how and when humble leaders are more effective.     

Women’s mobilisation in the Portuguese revolution: context and framing strategies

This article examines the role of women’s mobilisations related to the 1974 Portuguese revolution. An in-depth analysis of three women’s organisations through archival research and interviews with participants highlights the ways in which they participated in a cycle of contention between 1974 and 1977. Examination of framing strategies demonstrates the effects of political and cultural context. In particular, I demonstrate that movement–party alliances informed and constrained the diagnostic and prognostic frames of women’s movements on feminism and the revolution. Opportunity structures are shown to vary for different organisations within the same cycle of contention. Facing relatively closed opportunities, two of these organisations pursued framing strategies that articulated with the Left-dominated master frame of the cycle in order to carve out spaces for gender-specific demands while rejecting the label of feminism. The third organisation, instead, presented a countercultural frame that alienated the organisation from party and movement allies. Unable to overcome ideological divisions and rivalries, the three organisations perceived each other as competitors, rather than potential allies. While party–movement cooperation contributed to the emergence of a fractionalised women’s movement, it also provided important support structures to aid women’s organisations to mobilise in a cultural and political context that was closed to feminist demands.
