Adult Perception of Emotion Intensity in Human Infant Cries: Effects of Infant Age and Cry Acoustics

The relation between adult perception of emotion intensity in the cries of 1- and 6-month-old infants and the acoustic characteristics of the cries was examined. In the first study, adults who were inexperienced in child care rated 40 cries on 3 emotion intensity scales: anger, fear, and distress. The cries of 6-month-olds were rated as being significantly more intense. Different acoustic variables accounted for emotion intensity ratings for the 2 infant ages. Peak amplitude and noisiness of the cry predicted adult judgments of intensity ratings of 1-month-olds' cries; a measure of amplitude ratio (in 2 frequency bands) was the best predictor of intensity ratings of 6-month-olds' cries. In the second study, parents of infants rated the same cries on the same scales. They also rated the older infants' cries as being more intense. The 2 adult groups did not differ on their ratings, and a regression equation derived from one adult group predicted the other adult group's rating of the same infant age better than it predicted its own ratings for the other infant age. Infant age, and its associated acoustic features, seems to be a more important determinant of adults' perception of emotion intensity than are such adult characteristics as gender or infant-care experience.     

The Relation of Parental Affect and Control Behaviors to Children's Classroom Acceptance: A Concurrent and Predictive Analysis

The present study is a longitudinal examination of the relations between parental expressions of affect and parental control behaviors and children's classroom acceptance in kindergarten and first grade. One hundred-sixteen kindergarten-aged children and their parents were videotaped during physical play sessions and parents were rated on global affective and behavioral dimensions. Ratings of classroom social acceptance were provided by teachers and peers. Results indicated that parents' expressed positive and negative affect were related to children's classroom acceptance in kindergarten and in first grade. The most powerful and consistent predictor of children's social acceptance was fathers' expressed negative affect, particularly between father-son dyads. The current study emphasizes the importance of continued examination of linkages between the family and peer systems, especially with respect to the ways in which children's experiences in the family and school environments may mutually influence social development, and points to the need for further examination of the mechanisms by which multiple social contexts may influence children's behavior in the family and in school.     

Prevalence and predictors of out‐of‐field teaching in the first five years

Many new science teachers are assigned to teach subjects in which they have not been prepared, a practice referred to as out‐of‐field (OOF) teaching. Teaching OOF has been shown to negatively influence instruction and constrain teachers’ development. In this study, we explored the extent to which new secondary science teachers were assigned OOF across their first 5 years. Analysis of this longitudinal data set indicated that these assignments were common. While new science teachers were assigned to teach a variety of subjects over their first 5 years of teaching, they were not assigned more or fewer OOF courses over time. Furthermore, results indicated that teachers in certain situations are more likely than others to be assigned to teach OOF. Even with federal legislation in the United States seeking to eliminate OOF teaching, a large portion of new secondary science teachers are assigned to teach science disciplines for which they are inadequately prepared. Based on the findings of this study, it is worth exploring policy avenues that eliminate OOF teaching. Policymakers, administrators, and teacher educators should seek to provide supports, such as science‐specific induction programs designed for new teachers who are assigned OOF, and science teacher educators should prepare prospective teachers to teach multiple science disciplines. © 2017 Wiley Periodicals, Inc.

Behaviour State Analysis in Rett Syndrome: Continuous data reliability measurement

Awareness of optimal behaviour states of children with profound intellectual disability has been reported in the literature as a potentially useful tool for planning intervention within this population. Some arguments have been raised, however, which question the reliability and validity of previously published work on behaviour state analysis. This article sheds light on the debate by presenting two stages of a study of behaviour state analysis for eight girls with Rett syndrome. The results support Mudford, Hogg, and Roberts' (1997 Mudford, OC, Hogg, J and Roberts, J. 1997. Interobserver agreement and disagreement in continuous recording exemplified by measurement of behavior state, American Journal on Mental Retardation, 102: 54–66.  [Google Scholar], 1999 Mudford, OC, Hogg, J and Roberts, J. 1999. Behavior states: Now you see them, now you don't, American Journal of Mental Retardation, 104: 385–391.  [Google Scholar]) concerns with the pooling of participant data. The results of Stage 2 also suggest, however, that most categories of behaviour state can be reliably distinguished once definitions of behaviours for each state are clearly defined.     

“Sex Hormones” in Secondary School Biology Textbooks

This study explores the extent to which the term “sex hormone” is used in science textbooks, and whether the use of the term “sex hormone” is associated with pre-empirical concepts of sex dualism, in particular the misconceptions that these so-called “sex hormones” are sex specific and restricted to sex-related physiological functioning. We found that: (1) all the texts employed the term “sex hormone”; (2) in all texts estrogen is characterized as restricted to females and testosterone is characterized as restricted to males; and (3) in all texts testosterone and estrogen are discussed as exclusively involved in sex-related physiological roles. We conclude that (1) contemporary science textbooks preserve sex-dualistic models of steroid hormones (one sex, one “sex hormone”) that were rejected by medical science in the early 20th century and (2) use of the term “sex hormone” is associated with misconceptions regarding the presence and functions of steroid hormones in male and female bodies.

MEASUREMENT OF UNIVERSITY OUTPUT: MODEL AND CASE STUDY

A model for measuring output of university departments is developed. The model includes teaching, research and other activities. The weighting factors for each activity is given. The model is applied to the departments of the College of Commerce of Kuwait University. Discussions and recommendations are presented.     

Speculative method in digital education research

The question of ‘what works’ is currently dominating educational research, often to the exclusion of other kinds of inquiries and without enough recognition of its limitations. At the same time, digital education practice, policy and research over-emphasises control, efficiency and enhancement, neglecting the ‘not-yetness’ of technologies and practices which are uncertain and risky. As a result, digital education researchers require many more kinds of questions, and methods, in order to engage appropriately with the rapidly shifting terrain of digital education, to aim beyond determining ‘what works’ and to participate in ‘intelligent problem solving’ [Biesta, G. J. J. 2010, “Why ‘What Works’ Still Won’t Work: From Evidence-Based Education to Value-Based Education.” Studies in Philosophy and Education 29 (5): 491–503] and ‘inventive problem-making’ [Michael, M. 2012, “‘What Are We Busy Doing?’ Engaging the Idiot.” Science, Technology &; Human Values 37 (5): 528–554]. This paper introduces speculative methods as they are currently used in a range of social science and art and design disciplines, and argues for the relevance of these approaches to digital education. It synthesises critiques of education’s over-reliance on evidence-based research, and explores speculative methods in terms of epistemology, temporality and audience. Practice-based examples of the ‘teacherbot’, ‘artcasting’ and the ‘tweeting book’ illustrate speculative method in action, and highlight some of the tensions such approaches can generate, as well as their value and importance in the current educational research climate.
