And Baby Makes Four: Predictors of Attachment Security among Preschool-Age Firstborns during the Transition to Siblinghood

The present study examined preschool-age firstborns' adjustment to siblinghood, as indexed by security of firstborn-mother attachment, in a sample of 194 2-parent families. Security of firstborn attachment decreased significantly after a secondborn's birth, but the size of the decrease was smaller among firstborns under 24 months relative to 2–5-year-olds. Mothers' marital harmony and affective involvement with firstborns predicted firstborn security before and after the baby's birth, whereas mothers' psychiatric symptoms predicted firstborn security only after the birth. Post-hoc analyses of select subgroups revealed that mothers of firstborns with high security scores before the newborn's birth, regardless of whether scores remained high or dropped after the birth, showed higher levels of psychosocial and behavioral functioning than did mothers of firstborns with consistently low security scores at both time points. However, substantial drops in firstborn security after a secondborn's birth were associated with higher maternal psychiatric symptom scores both prior to and following the birth. Results suggest that quality of firstborn adjustment to siblinghood can be predicted from both structural and familial aspects of the firstborn environment.

The main determinants of an athlete's protein needs are their training regime and habitual nutrient intake. Most athletes ingest sufficient protein in their habitual diet. Additional protein will confer only a minimal, albeit arguably important, additional advantage. Given sufficient energy intake, lean body mass can be maintained within a wide range of protein intakes. Since there is limited evidence for harmful effects of a high protein intake and there is a metabolic rationale for the efficacy of an increase in protein, if muscle hypertrophy is the goal, a higher protein intake within the context of an athlete's overall dietary requirements may be beneficial. However, there are few convincing outcome data to indicate that the ingestion of a high amount of protein (2–3?g?·?kg^?1 BW?·?day^?1, where BW?=?body weight) is necessary. Current literature suggests that it may be too simplistic to rely on recommendations of a particular amount of protein per day. Acute studies suggest that for any given amount of protein, the metabolic response is dependent on other factors, including the timing of ingestion in relation to exercise and/or other nutrients, the composition of ingested amino acids and the type of protein.     

Extending Validity Evidence for Multidimensional Measures of Coaching Competency

This study extended validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS; Myers, Feltz, Maier, Wolfe, & Reckase, 2006) by examining use of the original rating scale structure and testing how measures related to satisfaction with the head coach within teams and between teams. Motivation, game strategy, technique, and character building comprised the dimensions of coaching competency. Data were collected from athletes (N = 585) nested within intercollegiate men's (g = 8) and women's (g = 13) soccer and women's ice hockey (g = 11) teams (G = 32). Validity concerns were observed for the original rating scale structure and the predicted positive relationship between motivation competency and satisfaction with the coach between teams. Validity evidence was offered for a condensed post hoc rating scale and the predicted relationship between motivation competency and satisfaction with the coach within teams.     

Beyond “green buildings:” exploring the effects of Jevons’ Paradox on the sustainability of archival practices

The sustainability of archival institutions will be greatly affected by attempts to mitigate their carbon footprint to meet the challenges of global climate change. This paper explores how recordkeeping practices may enhance or undermine the sustainability of archives. To enhance sustainability, it is a common practice to increase the efficiency of recordkeeping practices. However, increases to efficiency may lead to a phenomenon known as Jevons’ Paradox. Jevons’ Paradox occurs when improvements in efficiency to a system or process result in an increase in use (instead of a decrease) of a resource. The failure of the paperless office demonstrates Jevons’ Paradox, and it has wide implications for the future sustainability of repositories. This paper advances the notion that “green” technologies alone are not enough to ensure sustainability. They must be deployed in concert with a systematic use of archival practices and theories for environmental sustainability to be ensured.

Major survey design issues for the IEA Third International Mathematics and Science Study

He has been involved in international comparative studies of education since 1971. His current research is focused on integrating frameworks for the assessment of learning, ability and performance. He recently completed (with T. N. Postlethwaite) a volume reporting findings of the second science study of the International Association for the Evaluation of Educational Achievement (IEA).
