Targets of attack and defense in play-fighting of the Djungarian hamster Phodopus campbelli: Links to fighting and sex

Analysis of the body targets attacked and defended during play-fighting by juvenile Djungarian hamsters Phodopus campbelli revealed that about 70% of all attacks were directed at the mouth. If successfully contacted, the mouth was briefly licked and nuzzled. The remaining playful attacks were gentle bites directed at the rump, and to a lesser extent, the top of the head. During serious fighting the top of the head and the rump are targets of attack, whereas the mouth is not. Licking and nuzzling the mouth was found to be a behavior performed by adult males at the beginning of sexual encounters. Therefore, play-fighting in juvenile hamsters cannot be thought of merely as a form of “mock fighting” since the principal target is seemingly sexual, not agonistic. The data also show that of the sexual body targets contacted, adult females are more likely to defend the mouth. In this way it is suggested that targets attacked and defended during juvenile play-fighting are derived from adult contexts in which such targets are defended. This hypothesis accounts for the prevalence of agonistic targets in the play-fighting of many species, and may provide a rationale for classifying those amicable targets that are competed for during play-fighting.     

Hubert's multi-rater kappa revisited

There is a frequent need to measure the degree of agreement among R observers who independently classify n subjects within K nominal or ordinal categories. The most popular methods are usually kappa-type measurements. When R = 2, Cohen's kappa coefficient (weighted or not) is well known. When defined in the ordinal case while assuming quadratic weights, Cohen's kappa has the advantage of coinciding with the intraclass and concordance correlation coefficients. When R > 2, there are more discrepancies because the definition of the kappa coefficient depends on how the phrase ‘an agreement has occurred’ is interpreted. In this paper, Hubert's interpretation, that ‘an agreement occurs if and only if all raters agree on the categorization of an object’, is used, which leads to Hubert's (nominal) and Schuster and Smith's (ordinal) kappa coefficients. Formulae for the large-sample variances for the estimators of all these coefficients are given, allowing the latter to illustrate the different ways of carrying out inference and, with the use of simulation, to select the optimal procedure. In addition, it is shown that Schuster and Smith's kappa coefficient coincides with the intraclass and concordance correlation coefficients if the first coefficient is also defined assuming quadratic weights.     

Creation and humanity: Veli-Matti Kärkäinen's answer to the ultimate question

This article focuses on the third volume of Vel-Matti Kärkkäinen's systematic theology, titled Creation and Humanity. After a brief overview of the volume the article offers some clarification on the tenth chapter, especially on its interaction with paleontology. After that, two constructive observations follow. The first is related to Kärkkäinen's notion of the embeddedness of human nature, and the second is to further employ systems thinking in his constructive work on creation and human evolution.     

What a drag it is being relational: Developing planetary identities

Feminists scholars, among others, have long argued for a relational understanding of identity and the self. More recently queer theory and the new materialisms have taken that understanding and placed it within an evolutionary and planetary perspective. As most modern, western understandings of law, politics, and ethics take the individual as the base unit for reflection, what might this relational, planetary identity mean in terms of ethics? This brief essay explores some of the religious and theoretical supports for a relational, planetary self, and then develops a type of ethic that is based upon a critical romanticism for the planet.     

Fathers’ Dosage in Community-based Programs for Low-income Fathers

Community-based programs for low-income fathers often struggle to get fathers to attend services and activities. This paper reviews the literature examining approaches to measuring dosage in fatherhood programs, rates of dosage, influences on dosage, and the associations between dosage and fathers’ outcomes. Studies were limited to programs that conducted randomized control trials, quasi-experimental studies, and one-group pretest/post-test designs. Although most programs report low or moderate dosage levels, some programs achieve high levels of fathers’ participation in parenting, coparenting, and economic security classes. Few studies examined dosage in relation to father outcomes. All but one of seven studies reporting effects showed that higher dose levels had positive associations with outcomes such as engagement with children, parenting satisfaction and self-efficacy, perception of coparenting quality, payment of child support, and earnings from work. This paper discusses future directions for studying father's dosage in fatherhood programs.     

Parental Involvement and Adolescents’ Academic Achievement: Latent Profiles of Mother and Father Warmth as a Moderating Influence

Parental involvement in their adolescents’ education plays an important role in promoting their children's academic outcomes. Yet, more research is needed to examine the relationship between parenting practices and parental warmth as well as to consider the potential joint contribution of warmth from both fathers and mothers. Thus, the primary purpose of the current study is to examine the extent to which patterns of parental warmth across fathers and mothers moderate the association between parental involvement and adolescents’ grade point average (GPA) and school engagement behaviors. Latent profile analysis was conducted to identify disparate profiles of fathers’ and mothers’ warmth within a nationally representative sample of 2,306 youths (51% male; mean age = 15.31 years, SD = 1.50; 77% non-Hispanic White) residing in opposite-sex, two-parent families from Wave I and II of the National Longitudinal Study of Adolescent to Adult Health. Latent-class enumeration processes support a five-profile solution characterized by differences in levels of parental warmth and congruency across parents: (a) Congruent High Warmth, (b) Congruent Moderate Warmth, (c) Congruent Low Warmth, (d) Incongruent High Mother/Low Father Warmth, and (e) Incongruent Low Father/Lower Mother Warmth. Subsequent multiple linear regression analyses reveal a moderating effect for Congruent Low Warmth on the relationship between parental involvement and adolescents’ GPA. Ultimately, the results show that variation in parental warmth exists across fathers and mothers with differing impact on adolescents’ outcomes. Excluding one parent without considering the joint effects of both parents will not produce an accurate and precise understanding of parenting in research or practice.     

Discerning the Ministries of Women

In 1988, the historic Rhodes Inter-Orthodox Symposium on the Place of Women in the Orthodox Church encouraged, among other things, fuller participation of women in the life of the church. This article reports on the results of a study that solicited the views of Orthodox Christians regarding the participation of women in the life of the church. Nearly three-quarters of respondents clearly stated or intimated that they would like to see more opportunities for women to serve in the church. One-third of the respondents identified the issue of deaconesses in their essays. Responses here revealed a great diversity of experience, education, and opinion. Nevertheless, more than half of the respondents commenting on deaconesses showed an openness to this ministry. This may be a powerful measurement indicating that exploring the pastoral need for this and other ministries may well be long overdue.     

Reaching Up,Down, In,and Around: Couple and Family Coping During the Coronavirus Pandemic

The worldwide coronavirus (COVID-19) has had profound effects on all aspects of life: physical health, the ability to travel locally or to more distant destinations, material and financial resources, and psychosocial wellbeing. Couples, families, and communities and individual persons in those relationships have struggled to cope with emerging depression, anxiety, and trauma, and the rise of relational conflict. In this article, we suggest that the existential nature of the pandemic’s challenges requires more than just the usual psychosocial interventions. We propose a taxonomy of responses to foster coping and resilience—“Reaching Up, Down, In, and Around.” “Reaching Up” includes accessing spiritual, religious, and ethical values. “Reaching Down” includes ideas and practices that foster a revised relationship with the Earth and its resources, and that engage families to participate in activities that aid the Earth’s recovery from decades of human-caused damage. “Reaching In” represents a turn towards experiences available in the mind and in shared minds in relationships that provide pleasure, excitement, joy, and peace, given that external sources of these emotions are of limited availability due to quarantine. “Reaching Around” involves reframing the mandate for “social distancing” as fostering social connection and support while maintaining physical distancing. The challenges for family therapists, whose practices are confined largely to online therapy, and who are struggling with the same fears and constraints as those persons they are attempting to help, are also discussed.     

“Together towards a Banquet”: The Feast as Promise and Resistance in Together Towards Life and Contemporary Theological Discourse

This article explores the symbol of the feast, as proposed by the 2012 World Council of Churches’ affirmation Together towards Life: Mission and Evangelism in Changing Landscapes (TTL). The feast is introduced as an appropriate hermeneutic tool to account for the multi-layered and dynamic reality of human life in the presence of others and in the presence of God. Interpreting the feast, together with TTL, as a symbol of the liberation and reconciliation of the whole creation and of the celebration of life in response to the outreaching love of God, the article reflects on some contemporary theological voices arguing that God’s invitation to the feast of God’s kingdom is a central element of Christian existence. Such feasting is, among other things, characterized by the dynamics of facing, the presence of the other, the awareness of human corporeality, and the particularization of the other that can overcome the idolatrous power of death. Entering this conversation, the present article will argue that the symbol of the feast can helpfully be understood in its two-fold dynamics of promise and resistance. While giving assurance about the transformation of all reality in the coming reign of justice and peace, the symbol of the feast, with its emphasis on inclusiveness and equality, also empowers people to resist all life-denying forces. Walking with the rest of the creation “together towards a banquet,” Christians are thus enabled, it will be asserted, to discern and actively live their vocation.     

The Strategic Practice of “Fiesta” in a Latino Protestant Church: Religious Racialization and the Performance of Ethnic Identity

Founded and led by a U.S.-born white pastor, Amor Poderoso is a nondenominational, evangelical megachurch in El Paso, Texas, almost entirely composed of Mexican-Americans, recent Mexican immigrants, and current Mexican citizens. Ethnographic fieldwork from 2014 to 2017, supplemented with interviews with pastors, worship leaders, and attendees, reveal that much of congregational life orients around intentionally showcasing “Mexican” culture through sounds, images, and artifacts that appropriate an array of idealized ethnic references (e.g., food, dress, mannerisms, clichés) from Northern Mexico. Ongoing ethnic displays do not originate spontaneously or impromptu from membership but rather serve as a form of tactical authenticity derived from U.S. racial schemas mobilized by congregational leaders as a distinctive religious resource. Weekly worship services featuring dialect-inflected Spanish preaching and singing project ethnic signals that elicit connections to both a common ancestral heritage and a common religious identity. In short, church leaders at this southern border Latino church deliberately deploy sounds, images, and artifacts to assert racialized performances of being “Mexican” for distinctly religious purposes, especially evangelization. In the process, the distinctive practices of religious racialization effectively structure church members’ ethnic and religious identities around racial tropes to buttress a cogent corporate identity for enacting institutionalized evangelical narratives and legitimating charismatic authority.
