Classifying Speech Sonority Functional Data using a Projected Kolmogorov-Smirnov Approach

This paper addresses a linguistically motivated question of classification of functional data, namely the statistical classification of languages according to their rhythmic features. This is an important open problem in phonology. The analysis is based on the information provided by the sonority, which is an index of local regularity of the speech signal. Our main tool is the projected Kolmogorov-Smirnov test. This is a new goodness of fit test for functional data. The result obtained supports the linguistic conjecture of the existence of three rhythmic classes.     

Theory‐of‐mind during childhood: Investigating syntactic and executive contributions

Both syntax and Executive Functions (EF) are involved in Theory‐of‐Mind (ToM) but their contributory roles have mainly been studied separately. Moreover, researchers have mostly administered False Belief (FB) tasks while they may not be representative of all ToM abilities. Studies of adults give valuable information regarding whether syntax and EF are useful for ToM reasoning (i.e., Reasoning account), however, only the study of children brings direct evidence in favor of ToM emergence (i.e., Emergence account). Also, because the ToM tasks used often entail verbal and executive demands, the links observed could mostly result from such confounds (i.e., Expression account). We evaluated ToM, syntactic and EF abilities in 126 children (3‐11 y.o.) using a set of ToM tasks with minimal verbal and executive demands. Our goals were to assess (1) the hierarchical contribution of syntax and EF to ToM, (2) whether results previously obtained for FB tasks are representative of ToM in general, (3) whether the ToM‐syntax and ToM‐EF links are constant (i.e., Reasoning account) or decrease during development (i.e., Emergence accounts). Results of stepwise regression analyses showed a predominant role of syntax over EF to predict ToM abilities. The comparison of results for ToM and FB tasks showed that FB is not always representative of ToM. Finally, there was no moderating effect of age on the syntax‐ToM or EF‐ToM relations, thus suggestive of the Reasoning account rather than the Emergence account.     

Mission and Advocacy Structure: A Perspective from Human Service Organizations

Nonprofit organizations are expected to advocate for the needs of their clients. However, advocacy is often not part of organizational structure, which can create reactive rather than proactive responses. To explore this issue, this qualitative study examined the macro advocacy practices of a small group of organizations committed to advocacy. Using a mission-driven perspective, results showed that they had a common perception of advocacy, advocacy was implicit in their mission, and that while structure was elusive, decision making around advocacy was clear and issue selection was broadly informed. Recommendations such as harnessing the value placed on advocacy to create structures that can ensure it takes place and giving the charge to do advocacy to a specific staff person are included.     

Subjective Well-Being Structure: Confirmatory Factor Analysis in a Teachers’ Portuguese Sample

Authors consider that subjective well-being is a theoretical construct that includes three components: life satisfaction, positive affect and negative affect. Despite the numerous studies already conducted, divergences remain concerning how to conceptualize these components within a global structure of subjective well-being. This study aims to examine the dimensionality of the subjective well-being construct. A set of self-report questionnaires was used to assess life satisfaction, positive and negative affect in 397 teachers of primary and high schools. A model of a tripartite structure was tested using a confirmatory factor analysis. The results corroborate the premise that subjective well-being is a multidimensional construct that incorporates three components: life satisfaction, positive affect and negative affect. Our findings reinforce the viewpoint that these three components are moderately correlated and relatively independent and also strengthen the need for a complete SWB assessment that includes adequate measures of all three components.     

Pension reforms and gender: The case of Sweden

This article analyzes the effects of pension reform for men and women by comparing the outcomes in the system after reform to the outcomes under the prior system. The authors also study the incentive effects on labor supply. The size of the labor force, however, is also influenced by the rules for retirement, social insurance programs (e.g., sickness insurance and unemployment insurance), collective bargaining agreements, and seniority rules. Using a simulation model, the authors compare women's pension benefits and contributions to those of men in the new Swedish system and in the old. The analysis includes simulating the wage and employment histories of representative men and women and the pension benefits these are likely to generate under the old and new rules. After showing the results of this model, the authors describe and discuss the supplementary pension systems, that is, the negotiated collective agreement schemes and different pathways to retirement. Based on empirical evidence from Swedish and Latin America simulated data, the final section of the article discusses gender impact of pension rules and how to design pension, systems to ensure adequate pension benefits for both women and men.     

Labor Migration between Developing Countries: The Case of Paraguay and Argentina1

Despite the historical and numerical importance of international migration between Paraguay and Argentina, the socioeconomic forces affecting the dynamics of the flow remain largely unexplored. This article contributes to the understanding of migration movements between the Latin American countries by analyzing patterns of labor migration from two Paraguayan communities to Argentina. The analysis separates the process of migration into four segments representing different migration decisions that Paraguayan men face throughout their life course: first trip, first return, recurrent trips, and duration of additional trips. Results confirm that Paraguayan migration to Argentina is closely related to individual characteristics and wealth, the extent of migrant networks and experience, and changes in macroeconomic conditions. The relative importance of these factors on migration varies depending on the aspect of migration under consideration. More generally, the analysis shows that unlike migration between Mexico and the United States, Paraguayan migrants to Argentina tend to be positively selected with respect to educational attainment and skills. This reflects the higher transferability of skills between the two countries and the absence of large urban centers attracting internal migrants in Paraguay. In addition, results show that migration between Paraguay and Argentina is very responsive to fluctuations in macroeconomic conditions, particularly income differentials and peso over‐valuation. Government policies oriented towards the regulation of migration flows in the Southern Cone should pay closer attention to the impact of macroeconomic fluctuations on migration decisions, especially in the context of the Mercosur agreement.     

Trade Balance and Income Shocks: Experience of Transition Economies

This paper investigates the major sources of changes in the trade balance of four Central European and three Baltic transition economies with an emphasis on the difference between permanent and transitory disturbances to income. In all seven countries the findings support the hypothesis that transitory disturbances to income are the main determinants of changes in the trade balance. These results seem to be fairly consistent with inter-temporal models of trade balance, which view transitory shocks to income as the main source of variations in the trade balance. These results do not seem to support the view that productivity shocks alone generate most of the variation in the trade balance.      

Civic Literacy and Social Work Education: Results From a Multi-Site Study

Given the decline in civic literacy among Americans, social work educators can no longer assume that students come prepared with the civic knowledge necessary for competent advocacy or policy practice. This article examines rates of civic knowledge among social work students at four social work education programs across the United States (U.S.). Findings indicate that although social work students score higher than the general U.S. adult population, their civic knowledge scores are still low, with nearly a third of these students falling in the failing range. Results suggest that social work students need additional content on civic knowledge.     

Behavioral and Cognitive Readiness for School: Cross-domain Associations for Children Attending Head Start

Utilizing a diverse sample of 356 four-year-old children attending Head Start, this study examined the degree to which behavioral aspects of school readiness, including classroom participation, prosocial behavior, and aggression control were related to direct assessments of child cognitive readiness (academic knowledge, executive function skills) at the start of the prekindergarten year. Classroom participation and prosocial behavior each accounted for unique variance in cognitive readiness. Aggressive behavior, in contrast, was not correlated with academic knowledge, and was associated with low levels of executive function skills. In multiple regressions, aggressive behavior paradoxically enhanced the prediction of child cognitive readiness. Profile analyses strengthened the conclusion that the promotion of competencies associated with classroom participation and prosocial behavior may be particularly critical to cognitive readiness in prekindergarten. Implications are discussed for developmental models of school readiness and preschool classroom practice.     

Economies of Scope through Multi‐unit Skill Systems: The Organization of Large Design Firms

From a study of three large design firms in Italy, the UK and the USA, we derive a distinct model of how large knowledge‐intensive business services (KIBS) firms organize to manage growth and realize economies in ways that differ from the organizational techniques that are familiar from scale and scope studies of large manufacturing enterprises. Case studies were compiled from interviews conducted at the three firms. Large design firms were selected as a contrasting context to Chandlerian manufacturing firms. Design firms were expected to differ from manufacturing firms in terms of strategy, organization and the overall possibilities of achieving economies of scale and scope. Our results show that competitive advantage of these large KIBS design firms derives from a particular multi‐unit skill system that enables the firms to exploit economies of scope. There are four distinctive organizational features of such KIBS firms. First, multiple business units within the firm play a dual role. These are able both to engage in inter‐unit coordination and resource sharing and to attract business independently, often with heterogeneous business models among units. Second, these firms develop formal organizational routines for involving multiple business units in client projects, thus facilitating the migration of clients' business from one unit to another. Third, there is an important role for cross‐unit strategic ‘insight’ agents. Fourth, these firms expand through the founding of specialized, even idiosyncratic, new business units (often with the important role of mastering new technological skills).
