Whole-body angular momentum in a complex dance sequence: Differences across skill levels

Due to the redundant degrees of freedom (DOF) and nonlinearity of reactional kinetic elements within the human motor apparatus, controlling the complex dynamics of the human musculoskeletal system presents considerable difficulties. Based on this challenge, Bernstein (1967) viewed skill development as the process whereby the central nervous system (CNS) gains mastery of kinematic DOF and kinetic reactional elements (passive forces, moments etc.), with the highest level of skill characterised by optimal exploitation of reactional elements in the achievement of movement goals. A previous kinematic investigation into coordination differences in a complex multidirectional dance sequence demonstrated that general unfreezing of kinematic DOF occurred as dance skill progressed (Chang et al., submitted for publication). To gain insight into the role of angular reactional elements in skill, the present kinetic study investigated angular momentum and associated variables across three skill levels (beginners, intermediates, experts) within this same complex dance sequence. The results showed that the angular momenta of segments and accompanying angular reactional elements generally increased with skill level. More specifically, the findings suggested that while improvements in movement economy from cancellation of angular momentum between body segments occur early in skill progression, later in skill progression, experts utilise increased whole-body angular momentum. Although this is energetically expensive, it may enhance the aesthetic value of dance movements, and/or have mechanical advantages. Overall, the findings here provide support for Bernstein’s (1967) model of skill development. Future research should quantify the relations between energy expenditure, key biomechanical variables that reflect skill and dance aesthetics as perceived by audiences.     

“Get Off My Property”: A Personal Narrative Addressing Violence Against African Americans by Law Enforcement Post–Hurricane Katrina

Thousands of African American New Orleanians were displaced in the aftermath of Hurricane Katrina. It appeared that every African American suddenly became a suspect, “fair game” to be hunted, especially by the police. This autoethnography chronicles the author's personal background, experiences, and resulting emotions of her father's encounter with law enforcement post–Hurricane Katrina. Law enforcement–initiated interventions are explored. The article concludes with recommendations for members of the counseling profession and law enforcement. Miles de personas afroamericanas de Nueva Orleans perdieron sus hogares como consecuencia del huracán Katrina. Y de repente, cada persona afroamericana pareció convertirse en sospechosa, “presa legítima” para la caza, especialmente por parte de la policía. Esta autoetnografía documenta los orígenes personales y experiencias de la autora, así como las emociones resultantes de la interacción de su padre con las fuerzas policiales tras el huracán Katrina. Se exploran las intervenciones iniciadas por las fuerzas policiales. El artículo concluye con una serie de recomendaciones para los profesionales de la consejería y las fuerzas policiales.     

Still People of the Book A History of the Church in 100 Objects,Mike Aquilina and Grace Aquilina,Ave Maria, 2017 (ISBN 978‐1‐59471‐750‐5), 448 pp., pb $24.95

The recent turn to ‘material religion’ in the academic study of religion offers a new opportunity for scholars and practitioners to take the embodied, devotional lives of adherents seriously. In their new book, A History of the Church in 100 Objects, Mike and Grace Aquilina might be productively read as responding to this new openness on the part of scholars by presenting Roman Catholic history as told through those objects that have guided the practices of the faithful. Despite their protestations to the contrary, however, the story that they tell is still mostly determined by the authoritative interpretation of sacred texts instead of ordinary interactions with sacred objects.     

Becoming a ‘real’ Catholic: Polish migrants and lived religiosity in the UK and Ireland

The effect of migration on religiosity is a well-documented theme in the sociology of religion. Despite the rapid growth in the number of Polish Catholics in the UK and Ireland, little has been written on the spiritual and religious aspects of their journeys. This article is based on the authors’ ethnographic fieldwork with Polish migrants in the UK and Ireland. Drawing on qualitative interviews and participant observation with Polish migrants of various ages and class backgrounds, we identify three possible outcomes for individuals of Catholic faith being transplanted to a secular context: firstly, Catholic Poles continue to practise in the same way as they did in their home country; secondly, they begin to question their faith and leave the church altogether; thirdly, they take the opportunity to explore their faith in a flexible and relatively independent manner. We argue that the third possibility leads to the privatisation and intellectualisation of their Catholicism. Thus, the experience of migration gives some Polish Catholics the freedom and courage to question their beliefs, but it does not necessarily make them irreligious. In their own words, they ‘believe in the way they have always wanted to but did not dare’. In conclusion, this article highlights the secondary benefits of migration for the personal experience of religious faith.     

Paternal Caregivers’ Parenting Practices and Psychological Functioning among African American Youth Living in Urban Public Housing

Structural factors associated with public housing contribute to living environments that expose families to adverse life events that may in turn directly impact parenting and youth outcomes. However, despite the growth in research on fathers, research on families in public housing has practically excluded fathers and the role fathers play in the well‐being of their adolescents. Using a sample of 660 African American adolescents recruited from public housing, we examined the relationship between paternal caregivers’ (i.e., fathers’ and father figures’) parenting practices and adolescents’ depressive symptoms, attitudes toward deviance, and self‐efficacy. Using a latent profile analysis (LPA), we confirmed a four‐class model of paternal parenting practices ranging from high to low levels of monitoring and encouragement. Results from a one‐way ANOVA indicated that paternal caregivers with high (compared to moderate) levels of encouragement and monitoring were associated with youth who reported less depressive symptoms, higher levels of self‐efficacy, and less favorable attitudes toward deviance. Discriminant analysis results indicated that approximately half of the sample were correctly classified into two paternal caregiver classes. The findings provide evidence that some of these caregivers engage in parenting practices that support youths’ psychological functioning. More research is needed to determine what accounts for the variability in levels of paternal encouragement and supervision, including environmental influences, particularly for paternal caregivers exhibiting moderate‐to‐low levels of paternal encouragement and monitoring.     

Marital Expectations in Strong African American Marriages

The current exploratory study utilized a family strengths framework to identify marital expectations in 39 strong African American heterosexual marriages. Couples reflected on their marital expectations over their 10 or more years of marriage. Three themes emerged through qualitative analysis and the participants' own words were used in the presentation of the themes. African Americans indicated that there was growth in marital expectations over time, with marital expectations often beginning with unrealistic expectations that grew into more realistic expectations as their marriages progressed. Participants also indicated that core expectations in strong African American marriages included open communication, congruent values, and positive treatment of spouse. Finally, participants explained there is an “I” in marriage as they discussed the importance of autonomy within their marital relationships. Results are discussed in association with existing research and theory.     

Fear and its vicissitudes

Abstract

The USA has been a changed society since 9/11: the Zeitgeist either has a background of low-level angst, or when an attack occurs or a threat is sounded, the fear peaks and comes to the foreground for a time. Perhaps nothing demonstrates the degree to which fear permeates contemporary culture more than the continual presence of the measures the USA takes to be safe: airport security, the Patriot Act, the mining of formerly private information by the government, to name but a few. Can we account for the pervasive nature of fear solely by the devastating and deadly attacks 15 years ago, unspeakably horrifying though they were? This paper will explore this omnipresent fear in contemporary American culture from a psychoanalytic perspective, and in so doing hopes to shed light on the nature of that fear, why it is so persistent despite 15 years without any sequels, and what the consequences of that fear are for the American way of life. The discussion will be rounded out by linking this pervasive fear to the violence that is endemic to our age.     

On the emergence of American analytic philosophy

This paper is concerned with the reasons for the emergence and dominance of analytic philosophy in America. It closely examines the contents of, and changing editors at, The Philosophical Review, and provides a perspective on the contents of other leading philosophy journals. It suggests that analytic philosophy emerged prior to the 1950s in an environment characterized by a rich diversity of approaches to philosophy and that it came to dominate American philosophy at least in part due to its effective promotion by The Philosophical Review’s editors. Our picture of mid-twentieth-century American philosophy is different from existing ones, including those according to which the prominence of analytic philosophy in America was basically a matter of the natural affinity between American philosophy and analytic philosophy and those according to which the political climate at the time was hostile towards non-analytic approaches. Furthermore, our reconstruction suggests a new perspective on the nature of 1950s analytic philosophy.
