A comparative review of the primate motor system

Primates have evolved separately from other mammals since the late Cretaceous, and during this time the two major extant primate groups, prosimians (lorises, lemurs, and tarsiers) and anthropoids (monkeys, apes, and humans) arose. Concurrently, structures within the central nervous system acquired primate characteristics. Not all of the uniquely primate features have been identified in the brain, but several are well known. The pyramidal system, the best studied motor system, shows a distinct primate pattern in its terminal connections in the spinal cord. Other descending systems are less well known, but primate specializations in the vestibular system and red nucleus have been observed. The primary and secondary motor cortices are topographically separated in primates, suggesting one basis for increased complexity. Given the size of the brain, structures in the basal ganglia are relatively enlarged in primates as compared with other mammals, whereas the cerebellum has the same relative size.

Development and initial validation of brief public domain RIASEC marker scales

Although commercially developed interest measures based on Holland’s RIASEC types are effectively used in a variety of applied settings, these measures have somewhat limited research utility due to their length and copyright restrictions placed by the test publishers. In the present study, two sets of 8-item RIASEC scales were developed using activity-based items selected from the 30-item RIASEC scales of the Interest Profiler, and two sets of 8-item RIASEC scales were developed using sets of 30 occupational job titles selected from the O∗NET database representing each Holland type. Responses to the items were obtained from three samples of college students with a total of 1024 female and 639 male participants. Results obtained in the initial development and validation process suggest that the sets of brief activity- and occupational-based RIASEC scales developed in the current study retain acceptable levels of reliability and convergent validity. The development of these brief public domain RIASEC interest measures addresses the copyright and length limitations of current scales and may be useful when conducting integrative research examining the inter-relations between Holland’s types and other individual differences measures.     

The Church in the Contemporary Ecumenical‐Missional Moment: Together towards Life in Dialogue with The Cape Town Commitment and Evangelii Gaudium

The doctrine of the church has always been important to developments in mission and ecumenism – a fact that has been true since the birth of the modern ecumenical movement and is no less so today. This article compares three recent documents – the WCC's Together towards Life (2013), the Lausanne Movement's Cape Town Commitment (2011), and Pope Francis' exhortation Evangelii Gaudium (2014) – in light of the rise of a prominent new way of expressing the role of the church in the mission of Christ (missio Dei). This theological development has significantly impacted mission and ecumenical thinking and practice in recent decades, requiring us to consider the church's relationship to mission in a new and important way. The article reveals various aspects of missio Dei theology at work in all three of these documents, and finally looks at the visionary leadership of Pope Francis in calling the Catholic Church to a joyful expression of the gospel of Christ through both words and deeds. EG does not so much address the doctrine of the church as it assumes it. Its concern is far more pastoral: “How do we more effectively and powerfully communicate the gospel in our time?”     

Spirituality Among Older African Americans

Recent changes in gerontology have drawn attention to the role of spirituality among older adults. Demographic trends suggest that the number of African Americans over the age of 65 is increasing, with the largest shift to occur in persons 85 years of age and older. Given the paucity of information available regarding the relationship between spirituality and aging along with the increase in the number of older African Americans, a literature review of these concepts is sorely needed. This paper provides a thorough profile of older African Americans, with a review of historical and cultural factors that have informed the spiritual development of this population. Additionally, attention is given to methodological issues such as definitions, measures, sampling, and research designs at the interface of development and spirituality in this population. The paper also reviews findings to date about the effects of spirituality on physical and mental health among older African Americans.     

Preparing children for medical examinations: the importance of previous medical experience

The relationship between past medical experience and children's response to preparation for medical examinations was investigated in 79 pediatric outpatients aged 3 to 12 years. Children were randomly assigned to one of five preparation conditions prior to receiving a medical examination and a throat culture: sensory information about the exam, training in coping skills (deep breathing and positive self-talk), combined sensory information and coping skills training, attention control, and no-treatment control. The results indicated that children with previous negative medical experiences demonstrated more behavioral distress during a throat culture examination that did children with previous positive or neutral medical experiences. In addition, the attention control condition appeared to increase the distress of children with previous negative medical experiences. Amount of past exposure to the specific medical procedure was not related to observed distress. The implications of these findings for the preparation of children for medical procedures are discussed.

Production and elimination of disruptive classroom behavior by systematically varying teacher's behavior

The effects of teacher behaviors on the classroom behaviors of children were investigated by systematically varying approving (praise, smiles, contacts, etc.) and disapproving (verbal reprimands, physical restraint, etc.) classes of teacher behavior. Measures were taken on both teacher and child behaviors. Each day a sample of 10 children was observed. The subject pool was a class of 28 well-behaved children in a middle-primary public school class. The results demonstrated that approving teacher responses served a positive reinforcing function in maintaining appropriate classroom behaviors. Disruptive behaviors increased each time approving teacher behavior was withdrawn. When the teacher's disapproving behaviors were tripled, increases appeared most markedly in the gross motor and noise-making categories of disruptive behavior. The findings emphasize again the important role of the teacher in producing, maintaining, and eliminating disruptive as well as pro-social classroom behavior.     

Working for Group Pride in a Slipper Factory1

In a manufacturing firm the management provides daily production goals for a number of small assembly lines, and reports daily performance scores to the workers. In the research reported here, employees were asked after each of 3 weeks what goal they privately preferred their team to have in the future. On two occasions measures also were made of their desire for group success and their views toward their team and its task. It was observed that managers and workers alike preferred very difficult group goals, that workers with greater desire for pride in group more commonly preferred harder goals, and that stress was greater as the team functioned more poorly. Results in this natural setting resembled those in laboratory experiments.
