In secondary schools, subjects dominate teaching and also the organizational structures. Typically, subject department heads perform a middle-management role in secondary schools and often this role is taken-for-granted and unquestioned. In this article, we examine the impact on secondary school culture and the resulting changes to practice when the department middle-management structure and roles are open to revision. We investigate the experiences of two schools that are part of a longitudinal study on reculturing and restructuring in all secondary schools in one school district in Ontario, Canada. Our research indicates that structural change initiated by school level participants is a prerequisite to real change and that structural changes preceded cultural changes. However, it is the process of creating the new structures that is the key consideration as mandating an alternative might not be facilitative of cultural change. The primary research question guiding this article is: what impact does involvement in restructuring a middle-management organizational model have on the culture of a school and the change process experienced by staff members?

Auditory Frequency Resolution in Human Infancy

Frequency resolution is a fundamental capacity of the auditory system that underlies the perception of all complex sounds. The development of this capacity has not been well characterized in humans. This investigation used a nonsimultaneous pulsation threshold technique to examine the development of infant frequency resolution. Psychophysical tuning curves were obtained for 3- and 6-month-olds and for adults at either 500, 1,000, or 4,000 Hz. Both the sensation level and the sound pressure level of the stimulus were varied for adults to determine the contribution of stimulus intensity to age differences in frequency resolution. At 500 and 1,000 Hz, 3- and 6-month-olds' tuning curve widths were equivalent to adults'. At 4,000 Hz, the 3-month-olds' tuning curves were broader than those of 6-month-olds and adults, even when absolute sound pressure level was equivalent. The maturation of psychophysical frequency resolution in infants is discussed in terms of the general development of the auditory system and of nonsensory factors that might contribute to age differences in performance.     

‘The power to squash people’: understanding girls’ relational aggression

While researchers and concerned adults alike draw attention to relational aggression among girls, how this aggression is associated with girls’ agency remains a matter of debate. In this paper we explore relational aggression among girls designated by their peers as ‘popular’ in order to understand how social power constructs girls’ agency as aggression. We locate this power, hence girls’ agency, in contradictory messages about girlhood that, although ever‐present ‘in girls heads,’ are typically absent in adult panic about girls’ aggression. Within peer culture, power comes from the ability to invoke the unspoken ‘rules’ that police the boundaries of acceptable femininity. We thus challenge the notion advanced by Pipher and others that girls’ empowerment entails (re)gaining an ‘authentic voice.’ In contrast, we suggest that such projects must be informed by an interrogation of how girls are positioned as speaking subjects.     

Infant and Toddler Child-Care Quality and Stability in Relation to Proximal and Distal Academic and Social Outcomes

This study considered the quality and stability of infant and toddler nonparental child care from 6 to 36 months in relation to language, social, and academic skills measured proximally at 36 months and distally at kindergarten. Quality was measured separately as caregiver–child verbal interactions and caregiver sensitivity, and stability was measured as having fewer sequential child-care caregivers. This longitudinal examination involved a subsample (N = 1,055) from the Family Life Project, a representative sample of families living in rural counties in the United States. Structural equation modeling revealed that children who experienced more positive caregiver–child verbal interactions had higher 36-month language skills, which indirectly led to higher kindergarten academic and social skills. Children who experienced more caregiver stability had higher kindergarten social skills.     

What do prospective students look for in higher degrees by research? A scale development study

ABSTRACT

This empirical investigation was aimed at conceptualizing, developing and validating a scale for the measurement of the quality of higher degrees by research (HDR-QUAL). For that purpose, this study specifically measured perceptions of higher degrees by research (HDR) students about the constituents of HDR quality in Pakistani tertiary education institutions. Following the 7-step process of scale development, three studies were conducted in order to develop an initial pool of scale items, establishing proposed scale validity and reliability, and assessing nomological behavior of the proposed scale. The principal component analysis with Varimax rotation method resulted in a 3-factor solution, subsequently proposing a 15-item scale. The model fit indices of measurement and the higher-order model indicated a satisfactory fit to data. Finally, the resultant three factors, i.e. financial assistance, supervisory expertise, and infrastructural support, converged into a unidimensional HDR-QUAL scale that was found positively associated with student satisfaction, thus, confirming nomological validity as well. Important policy measures and directions for future research are proposed at the end.
