Production efficiency and constraints on profit taxation and profit distribution in economies with Ramsey taxation

In economies with Ramsey taxation, decreasing returns to scale, and private ownership, we show that second-best production efficiency is desirable when the grouping of private firms induced by the profit taxation power of the government is at least as fine as the grouping of firms induced by the institutional rules of profit distribution in the economy. The classic results of Dasgupta and Stiglitz (Rev Econ Stud 39:87–103, 1972) (of firm-specific profit taxation) and Diamond and Mirrlees (Am Econ Rev 61:8–27, 1971a; Am Econ Rev 61:261–278, 1971b) and Guesnerie (A contribution to the pure theory of taxation, 1995) (of uniform 100 % profit taxation) follow as special cases of our model. Moreover, second-best analysis shows that optimal profit taxation is a substitute for optimal intermediate input taxation. In smooth economies, proportional, lump-sum, and affine modes of profit taxation are equivalent. We rework Mirrlees (Rev Econ Stud 39:105–111, 1972) counterexample, which is posed in the context of a non-smooth economy, to show that second-best production efficiency continues to remain desirable under an affine structure of profit taxation.     

The Opportunities for Adopting Inflation Targeting in Tunisia: a Cointegration Study and Transmission Channels of Monetary Policy

The major aim of this paper is to analyze, at a first stage, the trend of inflation in Tunisia, then to conduct an overview of inflation measures and, to develop a simple inflation forecasting by applying the Box and Jenkins (Time series analysis: forecasting and control. Holden day, San Francisco, 1976) method. It is essential to understand the dynamics of the core and global inflation, and to explore the relationships that may undermine cointegration inflation via the Engle and Granger (Econometrica 55:251–276, 1987) and Johansen (J Econ Dyn Control 12:231–254, 1988) methods on control variables during a recent monthly period, ranging from 1996 to 2006. Concerning the Tunisian case, and by retracing the similar study conducted by Ndiyae and Badji (Les déterminants de l’inflation au Sénégal: Approche par les fonctions de consommations, Agence nationale de la statistique et de la méthodologie, 2008), the results have shown the existence of just a single cointegration relationship between the variables concerning a short term and long-term dynamics. Moreover, within the same spirit, a structural analysis based on structural VAR of Blanchard and Quah (Am Econ Rev 79:655–673, 1989) method has managed to identify the shocks impact on the supply and demand variables on the consumer prices index through the study of transmission channels of monetary policy. The outcomes have exposed that the relatively low impact degree of control variables on inflation in Tunisia is consistent with those carried out by Gupta and Komen (Time aggregation and the contradictions with causal relationships: can economic theory come to the rescue? 2008).     

Rap Music and the Empowerment of Today’s Youth: Evidence in Everyday Music Listening, Music Therapy, and Commercial Rap Music

Pioneers of various elements of Hip-Hop culture have been empowered through the ability to voice their reality and find a meaningful identity alongside others who found purpose and function in embracing Hip-Hop culture (Chang, Can’t stop won’t stop: A history of the hip-hop generation, 2005). This empowerment persists in various reinventions of the culture within the United States and worldwide. The present study examines whether evidence exists in research to support the value of esteem, resilience, growth, community and change as empowering dimensions outlined in the individual and community empowerment framework. Research questions ask: (1) Does youth self-expression in rap music created within music therapy sessions reflect framework dimensions? (2) Does content in commercially recognizable rap music reflect framework dimensions? (3) How well does the framework align with a model of empowerment-based positive youth development? First, data collected to examine the validity of the framework were reviewed. Next, two peer-reviewed research studies published after articulation of the original framework, were examined to investigate commonality between themes and framework dimensions. One study was in a music therapy context and another explored themes in commercial Hip-Hop recordings. Original framework data supports theorizing that rap music content actually comprises developmental narratives (Travis and Deepak, 2011; Travis and Bowman, 2012). Data in the present study further suggest that these developmental narratives are relevant for Hip-Hop in every day music engagement, in therapeutic self-expression, and within commercially available musical content. Framework dimensions also aligned with a conceptual model of positive youth development that allows specification of intervention pathways and empirically testable outcomes for Hip-Hop integrated change strategies. Results suggest that rap music is a discourse in lifespan development. Rap music’s developmental narratives may be used by practitioners, parents and researchers. The narratives exist within a framework and model that (a) provides a template for better understanding these narratives and (b) positions this understanding for use as a tool to promote and research positive change strategies for individuals and the communities that they value.     

Propositionwise judgment aggregation: the general case

In the theory of judgment aggregation, it is known for which agendas of propositions it is possible to aggregate individual judgments into collective ones in accordance with the Arrow-inspired requirements of universal domain, collective rationality, unanimity preservation, non-dictatorship and propositionwise independence. But it is only partially known (e.g., only in the monotonic case) for which agendas it is possible to respect additional requirements, notably non-oligarchy, anonymity, no individual veto power, or extended unanimity preservation. We fully characterize the agendas for which there are such possibilities, thereby answering the most salient open questions about propositionwise judgment aggregation. Our results build on earlier results by Nehring and Puppe (Strategy-proof social choice on single-peaked domains: possibility, impossibility and the space between, 2002), Nehring (Oligarchies in judgment aggregation: a characterization, 2006), Dietrich and List (Soc Choice Welf 29(1):19–33, 2007a) and Dokow and Holzman (J Econ Theory 145(2):495–511, 2010a).     

Modeling resource flow asymmetries using condensation networks

This paper examines strict Nash networks in the noncooperative directed flow model of Bala and Goyal (Econometrica 68(5):1181–1230, 2000) with partner heterogeneity (payoff of a player in a link depends on the identity of her link partner). We focus on the asymmetries with regard to the resources obtained by players. Using the notion of condensation networks, we partition the population into groups of players who obtain the same resources and order these groups according to the resources they obtain. We show that the partner heterogeneity assumption impacts the strict Nash networks asymmetries in a different way than Galeotti (Econ Theory 29(1):163–179, 2006) player heterogeneity assumption (the payoff of a player in a link depends on her own identity).     

Sorokin as Lifelong Russian Intellectual: The Enactment of an Historically Rooted Sensibility

Prior to his 1922 emigration to Europe and thence to the United States, Pitirim Alexandrovich Sorokin had an exceptional intellectual and political career in Russia and the Soviet Union (Sorokin 1924, 1963a; Johnston 1995; Krotov 2005). Indeed, he was among the early founders of the science of sociology in his native land, where, according to a relatively recent bibliography (Sorokin 2000), he produced 162 Russian-language publications between the ages of 21 and 33. This listing includes not only book reviews and journal articles, but also substantial monographs and a two-volume theoretical treatise. While still a relatively young man, Sorokin had thus gained widespread recognition as a scholar of the first rank. He was also the initial chairperson (from 1919 to 1922) of a fledgling department of sociology at the University of Petrograd (St. Petersburg), an elected member of the national Constituent Assembly and an appointed staff member of the 1917 Provisional Government, the first democratic regime in Russia. This much would have sufficed for an entry in a sociological encyclopedia, and Sorokin’s political career has few parallels in the history of the field, other than the involvement of Emile Durkheim in French educational policy and the participation of Max Weber in creating the Weimar Republic in Germany. Nevertheless sociologists in the United States and most western historians of the field have not yet appreciated the full influence of the formative period, especially from 1905 to 1922. Lacking familiarity with Russian culture of that era and knowing little about the larger Russian socio-historical milieu, its intellectual discourse and collective memory, they have not been able to comprehend Sorokin’s outlook, behavior and professional output in the United States in relation to these earlier contextual factors. This is arguably a fundamental reason why many U.S. sociologists have tended to see Sorokin, especially since 1937, as a marginal figure and to regard his works largely as deviations from accepted social scientific practice. This paper will argue that a more adequate appreciation of Sorokin’s background and early adult life illumines both stylistic features of his works in America and also places into proper perspective several of his substantive foci that did not accord with contemporary “normal science” (Kuhn 1962). In short, despite his overall assimilation into American society and higher education, including his appointment at Harvard University and his election as president of the American Sociological Association, Sorokin should be understood in large measure as a life-long Russian intellectual. His was a Russian-born sensibility and consciousness—indeed a “Russian soul”—so deeply ingrained that it stamped his entire professional career in the United States, including his published researches, his popular sociology and his university teaching.     

The Internalization of the “Father” Object Among Young Men and Its Relation to Separation–Individuation Patterns, Anxiety and Depression

While the father’s influence on his offspring’s personalities and well-being has historically been neglected, literature on this topic has recently been accumulating. The father’s influence is touches upon numerous practical and ethical implications for social work, psychotherapy, and psychodiagnosis. The present study draws from Mahler’s (Mahler, Separation individuation. The selected papers of Margaret S. Mahler, 1963, 1967, 1974; Mahler et al., The psychological birth of the human infant. Symbiosis and individuation, 1975) theory of the psychological birth of the child and offers a novel focus on the pivotal internal representation of the father. According to this theory, hindered developmental processes lead to depression and anxiety. 130 students took part in the current study, in which the internal father object was examined with regard to separation–individuation processes, and the levels of anxiety and depression were recorded. The study’s results show a significant negative relation between the quality of the paternal object and levels of anxiety and depression. A theoretical model was constructed to illustrate the similarities and discrepancies in the development of depression and anxiety in light of the father object as mediated by the separation–individuation processes that were examined.     

Generalized average rules as stable Nash mechanisms to implement generalized median rules

We consider a problem in which a policy is chosen from a one-dimensional set over which voters have single-peaked preferences. While Moulin (Public Choice 35:437–455, 1980) and others subsequent works have focused on strategy-proof rules, Renault and Trannoy (Mimeo 2011) and Renault and Trannoy (J Pub Econ Theory 7:169–199, 2005) have shown that the average rule implements a generalized median rule in Nash equilibria and provide an interpretation of the parameters in Moulin’s rule. In this article, we first extend their result by showing that a wide range of voting rules which includes the average rule can implement Moulin’s rule in Nash equilibria. Moreover, we show additionally that within this class, generalized average rules are Cournot stable. That is, from any strategy profile, any best response path must converge to a Nash equilibrium.     

Old and novel methods for estimating Feral Pigeons (Columba livia f. domestica) population size: a reply to Amoruso et al. (2013)

In a recent paper Amoruso et al. (2013) proposed a novel method for estimating population size of Feral Pigeons, the Superimposed Urban Strata (SUS) method. In our reply we firstly comment on the lack of a complete review of the available literature. Secondly we point out that the SUS method does not account for birds detection probability and thus it is just a simple index of abundance as many others proposed in recent years. Thirdly, we question the approach used by the authors to evaluate the reliability of their method. To conclude, we believe that the SUS method is not truly innovative and that further investigations are needed before considering it as a reliable way for estimating Feral Pigeons populations size.     

A Critical Examination of an Urban-Based Youth Empowerment Strategy: The Teen Empowerment Program

ABSTRACT

Youths from marginalized and disenfranchised communities can be empowered to advocate for social justice through civic engagement and sociopolitical action. Examining youth empowerment programs, using critical social theory, builds upon our understanding of sociopolitical systems and oppression and provides a lens to examine mechanisms of change while applying theory to practice. Jennings, Parra-Medina, Messias, and McLoughlin (2006 Jennings, L. B., Parra-Medina, D. M., Messias, D. K. H. and McLoughlin, K. 2006. Toward a critical social theory of youth empowerment. Journal of Community Practice, 14: 31–55. [Taylor & Francis Online] , [Google Scholar]) have identified six dimensions of critical youth empowerment programs, which provide a framework for examining youth empowerment programs. This article presents the Teen Empowerment program, as implemented with high-risk youths in urban communities, and examines it along these six dimensions and provides a model for how to critically examine youth empowerment programs using this framework.     

Internet Gambling Among High School Students in Hong Kong

The study investigated Internet gambling involvement and pathological gambling among Hong Kong adolescents aged 12–19 years. The diagnostic and statistical manual (4th edition) multiple response format for juveniles (DSM-IV-MR-J) (Fisher in J Gambl Stud 16:253–273, 2000) was filled by 1,004 students (597 boys, 407 girls) recruited by random selection of classes. The response rate was 86.6 %. Results indicate that more respondents participated in land-based gambling than Internet gambling (63.5 vs. 3.5 %) but online gamblers are 1.5 and 3.2 times more likely to develop pathological and at-risk gambling than non-Internet gamblers. Using the DSM-IV-MR-J criteria, 5.7 and 22.9 % of the Internet gamblers could be classified as at-risk gamblers and pathological gamblers, respectively. Majority (94.3 %) wagered online at home, and 91.4 % made their first bet before 18 years. Many perceived Internet gambling as a trendy (71.4 %) and safe entertainment (54.3 %). Problematic Internet gambling was significantly associated with the male gender, school grades, online gambling frequency, amount wagered and a gambling family environment. Survey results have implications for gambling research and preventive programs.     

Physical activity and patient-reported outcomes: enhancing impact

Physical activity (PA) is beneficial for cancer survivors across the cancer trajectory. Evidence indicates physical and psychosocial benefits, and ultimately, enhanced overall quality of life, for individuals who are more versus less active (Semin Oncol Nurs 23:285–296, 2007; Cancer Epidemiol Biomarkers Prev 14:1672–1680, 2005; J Cancer Surviv 4:87–100, 2010). A number of recent reviews have been conducted that examine different patient or survivor populations and outcomes. In general, the findings across the reviews reveal potential positive associations between exercise (structured activity one engages in for the purposes of enhancing health-related fitness outcomes) and PA (any physical movement, including lifestyle types of activity) with both physical and psychological outcomes. It is important to note, however, that depending on the nature of the review and the types of studies included in the review, the strength of the findings (i.e., effect size) vary. Despite this overwhelmingly positive evidence for the benefits of PA, activity levels are very low among cancer survivors, with one study reporting only 22 % of survivors as active enough to achieve health benefits (Cancer 112(11):2475–2482, 2008). This suggests that we must begin to better understand the factors that impact the uptake and maintenance of PA among cancer survivors. These potential factors are important when considering the patient-reported outcomes to assess and can include timing (i.e., during or after treatment completion), characteristics of the cancer diagnosis and subsequent treatments (i.e., early vs. late stage cancers), and characteristics of the individual (i.e., older vs. younger).     

Are Gambling Related Cognitions in Adolescence Multidimensional?: Factor Structure of the Gambling Related Cognitions Scale

The present study examined the factor structure of the Gambling Related Cognitions Scale (GRCS); (Raylu and Oei in Addiction 99:757–769, 2004) in a large sample of adolescents (N = 1,490) between the ages of 16 and 18 years (630 males, 860 females) attending several high schools in central Ontario. Problem gambling was measured using the DSM-IV-J (Fisher in J Gambl Stud 8:263–285, 1992). A 5-factor GRCS model was found to have the best fit to the data, and gambling-related cognitions were found to be powerful predictors of disordered gambling among adolescents. However, strong associations among GRCS subscales, as well as the small amount of variance in problem gambling accounted for by specific GRCS subscales, call into question the multidimensionality of the GRCS when used with adolescents.     

Competing Drivers of Hybridity: Third-Sector Housing Organisations in Northern Ireland

This paper explores the complex process of hybridisation of third-sector housing and support organisations (TSOs) in Northern Ireland. The focus of the study is the policy field of housing-related support services, known in the UK as ‘Supporting People’. This is a hybrid policy field involving several government departments, a number of market mechanisms and two types of third-sector actors. The exercise of organisational agency to adapt to competing drivers is illuminated through mental health and homelessness case studies. The paper explores how competing external influences from the Northern Ireland Assembly, horizontal policies for the third-sector and vertical service commissioning policies interact with TSOs’ own adaptation strategies involving the deployment of robust third-sector identities. Hybridisation is found to involve not only the dominance of state drivers and the promotion of market mechanisms in both fields, but also enactment of third-sector identities. Our analysis of hybridization in this case counters Billis’ (2010) representation of third-sector identity as weak, in flux, and subject to erosion by focusing on the agency of TSOs to strategically adapt to and negotiate external drivers and thereby achieve competitive advantage. Through the enactment of identity in this adaptation process, resources such as legitimacy, charitable income and volunteers are secured. This provides opportunities for policy makers to add value if they are prepared to emphasise horizontal over vertical policy goals.     

Expected fair allocation in farsighted network formation

I consider situations in which a group of players extracts a value if they organise themselves in different network structures, and I define a solution concept to describe the decentralised decision that determines the network formation process and the allocation of the value. I demonstrate that there is a solution concept satisfying discounted expected versions of pairwise stability (Jackson and Wolinsky J Econ Theory 71:44–74, 1996) and fairness (Myerson Math Oper Res 2:225–229, 1977a) jointly with the requirement that the allocation rule be component efficient if the players’ discount factor is sufficiently low.     

Distorted Lorenz curves: models and comparisons

The economic literature contains many parametric models for the Lorenz curve. A number of these models can be obtained by distorting an original Lorenz curve $L$ by a function $h$ , giving rise to a distorted Lorenz curve ${\widetilde{L}}=h\circ L$ . In this paper, we study, in a unified framework, this family of curves. First, we explore the role of these curves in the context of the axiomatic structure of Aaberge (2001) for orderings on the set of Lorenz curves. Then, we describe some particular models and investigate how changes in the parameters in the baseline Lorenz curve $L$ affect the transformed curve ${\widetilde{L}}$ . Our results are stated in terms of preservation of some stochastic orders between two Lorenz curves when both are distorted by a common function.     

Assessment of the distributive impact of national trade reforms in Brazil

This paper quantifies the distributional and poverty effects of trade liberalization in Brazil using household survey data. We estimate the consumption and labor impact of Mercosur trade reform following the methodology suggested by Porto (J Int Econ 70:140–160, 2006) and Nicita (J Dev Econ 89(1):19–27, 2009). Results show that trade liberalization had a pro-poor effect in Brazil. This result is largely explained by two major observations: the fact that consumption good prices decreased after Brazil entered Mercosur and a close to zero labor income effect. We find that poverty decreased after national trade liberalization (both for women and men). Additionally, we obtained no significant inequality effects after national trade reforms.     

Children's Development as Participation in Everyday Practices across Different Institutions

Children participate in different institutional collectives in their everyday life. Home, school, and kindergarten are the institutional contexts that most children share. Although there are variations between home practices and school practices, they collectively share a common core framed by societal conditions. In drawing upon Vygotsky's (1998) Vygotsky, L. S. 1998. The collected works of L. S. Vygotsky (M. J. Hall, Trans., Vol. 5, Child Psychology), New York: Kluwer Academic/Plenum.  [Google Scholar] theory of the social situation of development and Hedegaard's (2009) Hedegaard, M. 2009. “Children's development from a cultural-historical approach: Children's activity in everyday local settings as foundation for their development”. In Mind, Culture, and Activity Vol. 16, 64–82. [Taylor & Francis Online] , [Google Scholar] theory of development conceptualised as the child's participation within and across several institutions at the same time, it has been possible to examine how school practices influence home practice and the child's social situation of development. A case study of an Australian child's participation across different institutions (family and school) was undertaken to capture and analyse the dynamic processes through which development was afforded. In the case study there was a large disjunction between institutional practices of the home and school that the child had to negotiate. Due to teacher knowledge of only the child's relation to the school institution, and not the home institution, the affordances for development and the child's changing relations to his environment, were invisible to the educators in this study. The findings suggest foregrounding an understanding of children's development as changes in children's activities and thereby changing their relations to reality across institutional practices in order to support a broader view of development in early childhood education.
