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.     

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.     

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).     

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.     

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).     

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.     

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.     

Patterns of Nonverbal Behavior Associated with Truth and Deception: Illustrations from Three Experiments

The digital age has brought with it new and powerful computer-based methods of analyzing heretofore elusive patterns of nonverbal behavior. C-BAS (Meservy 2010) is a computer-assisted behavioral observation tool for identifying and tracking nonverbal behaviors from video. THEME (Magnusson, The hidden structure of interaction: from neurons to culture patterns, IOS Press, Amsterdam, pp 4–22, 2005) is a software program that discovers patterns among discrete events in time-ordered data. Together, these tools enable more precise measurement and analysis of nonverbal behavioral dynamics. Applications to three corpora derived from interpersonal deception experiments reveal unique nonverbal patterns that distinguish deceptive from nondeceptive interactions. The first and second experiments produced serial, hierarchically related patterns of behaviors that differed in length and complexity between truthful and deceptive participants during interviews about a theft and cheating, respectively. The third experiment produced differential patterns by and among group members completing a task. Deceivers were inclined toward strategic initiations and interactional control, whereas suspicious group members adopted a more passive, possibly watchful stance. Discovery of these patterns challenges the prevailing view that nonverbal behaviors are too faint and inconsistent to identify deceptive communication. Results have numerous implications regarding the following: the development of new measurement tools locating significant effects of nonverbal behaviors, support for theory that coherent and repetitive relationships exist within and among interactants’ communication, demonstration of the role of nonverbal behaviors in deceptive communication and the dynamic and strategic nature of deception.     

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.     

Accuracy of Inferring Self- and Other-Preferences from Spontaneous Facial Expressions

Participants?? faces were covertly recorded while they rated the attractiveness of people, the decorative appeal of paintings, and the cuteness of animals. Ratings employed a continuous scale. The same participants then returned and tried to guess ratings from 3-s videotapes of themselves and other targets. Performance was above chance in all three stimulus categories, thereby replicating the results of an earlier study (North et al. in J Exp Soc Psychol 46(6):1109?C1113, 2010) but this time using a more sensitive rating procedure. Across conditions, accuracy in reading one??s own face was not reliably better than other-accuracy. We discuss our findings in the context of ??simulation?? theories of face-based emotion recognition (Goldman in The philosophy, psychology, and neuroscience of mindreading. Oxford University Press, Oxford, 2006) and the larger body of accuracy research.     

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.     

The ��Semiotic Self��: From Peirce and Mead to Wiley and Singer

Norbert Wiley (1994) provides a synthesis of Peirce??s and Mead??s views on the self. The Peirce-Mead ideal type model of the self involves the I and the me as well as the I and the you. Hence, at each moment we are a combined ??me-I-you?? in past, present and future. Milton Singer (1989) discovers the semiotic self through his anthropological research, but does not apply the concept as rigorously as one might hope. Peirce??s triadic epistemology and Pragmatism is explored to frame his contribution to the semiotic self. His categories of Firstness, Secondnes and Thirdness are briefly considered. Some anecdotal information about the self in Indic Civilization is discussed. It is argued that the INSOR model can be useful. The key is to move beyond Cartesian notions and to see the semotic self as a ??semiotic object,?? always subject to interpretation by the person engaged in symbolic interaction and exchange.     

Note on social choice allocation in exchange economies with Cobb–Douglas preferences

We show that in a pure exchange economy with two agents and a finite number of goods, there exists no strategy-proof, Pareto-efficient, and non-dictatorial social choice allocation function on any local Cobb–Douglas preference domain. This is a slight extension of a result proved by Hashimoto (2008).     

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.
