1. Variations in Pre-Service Teachers' Career Exploration and Commitment to Teaching

Author

Hong, Ji, Greene, Barbara, Roberson, Robin, Cross Francis, Dionne, and Rapacki Keenan, Lauren

Abstract

The purpose of this study was to investigate various career paths pre-service teachers explore and the processes of establishing their commitment to becoming a teacher. A mixed-methods design was employed; 326 surveys measured the levels of pre-service teachers' career exploration and commitment using occupational identity status (achievement, moratorium, foreclosure, and diffusion), along with resilience and perceived instrumentality. Thirty-two interviews were followed to further explore detailed variations of their career decision-making journey. MANOVA analysis indicated significant differences for resilience and perceived instrumentality based on the four occupational identity statuses. Subsequent qualitative analysis identified various patterns where pre-service teachers differed in their entry motivation, negotiation for their career decision making, and the strength of their commitment to teaching. The findings of this study illuminate iterative and non-linear development of pre-service teachers' professional identity.

Poggi (a)(b), Catherine Y. Spong (a) Abstract: In humans, cerebral palsy (CP) may originate from inflammation during the second and third trimesters of gestation when preoligodendrocytes (Pre-OL) are most vulnerable to an inflammatory insult. We studied a postnatal CP model to evaluate injury that would correlate with presence of Pre-OL in human pregnancy.

26. Oral arginine-lysine does not increase growth hormone or insulin-like growth factor-I in old men

Abstract

Arginine and lysine administered to young adults has been shown to increase secretion of growth hormone (GH), which can decrease body fat, assist in nitrogen retention and increase plasma insulin-like growth factor (IFG-I) levels. Since aging is associated with lower GH secretion, the efficacy of arginine and lysine for increasing GH in older men was investigated. Two groups of healthy older males were given either a 50/50 arginine-lysine mix or a placebo for two weeks. Although absorption level was similar in both groups, the arginine-lysine treatment had minimal effect on GH and IGF-I.

Spong (a) Keywords: Down syndrome; [gamma]-aminobutyric acid; learning; N-methyl-D-aspartic acid; NAPVSIPQ; SALLRSIPA; Ts65Dn Abstract: Down syndrome (DS) affects 1/800 infants. Prenatal NAPVSIPQ (NAP) and SALLRSIPA (SAL) (NAP+SAL) prevent developmental delay in Ts65Dn mice, a mouse model of DS. We investigated whether this finding involves N-methyl-D-aspartic acid and [gamma]-aminobutyric acid (GABA) receptor subunits.

Spong Keywords: fetal alcohol syndrome; [gamma]-aminobutyric acid A (GABA); N-methyl-D-aspartate (NMDA); mouse; learning Abstract: Prenatal alcohol exposure affects 1 in 100 births in the United States and results in craniofacial dysmorphologic condition and learning disabilities. In a model for fetal alcohol syndrome, neuroprotective peptides prevented fetal death and learning deficits. The [gamma]-aminobutyric acid A (GABA) receptor subunit GABA[beta]3 plays a critical role for nervous system and palate development. Our objective was to determine whether the neuropeptides prevented alcohol-induced damage through GABA[beta]3.
