Iodine is necessary for thyroid hormones synthesis which in turn are essential for brain development during fetal and early postnatal life. In these critical periods, severe iodine deficiency can induce irreversible brain damage in the fetus and the infant, resulting in retarded cognitive and/or psychomotor development. Despite the introduction of salt iodization programs such as national measures to control iodine deficiency, some European countries, including Belgium, are still affected by Mild Iodine Deficiency (MID) and MID during pregnancy may affect neurodevelopment of the offspring. Elevated thyroid stimulating hormone (TSH) concentration (>5mU/l) at birth has been used as an indicator of iodine deficiency during late pregnancy and at the population level. This doctoral research aimed to investigate the association between neonatal TSH level, used as a surrogate marker of MID during late pregnancy, and cognitive, psychomotor and psychosocial development of preschool children. It was hypothesized that elevation of TSH at birth is associated with impaired intellectual and psychomotor development and with behavioral problems at 4-5 years. As the use of TSH as an indicator of iodine deficiency has been criticized, we have also set out to assess the potential factors influencing neonatal TSH level measured through neonatal screening using a representative sample of TSH values between 0 and 15 mIU/L. Additionally, we aimed to reevaluate the neonatal TSH cut-off (5mIU/L) used to monitor iodine status in the population. The objective was to evaluate the cut-off point from which we can observe the impairment of children’s neurodevelopment. We hypothesized that this is a good way to establish the best cut-off value for identifying iodine deficiency.The study included 315 Belgian preschool children with a TSH concentration between 0 and 15 mU/L at screening. For each sex and TSH-interval (0-1 mU/L, 1-2 mU/L, 2-3 mU/L, 3-4 mU/L, 4-5 mU/L, 5-6 mU/L, 6-7 mU/L, 7-8 mU/L, 8-9 mU/L, 9-15 mU/L) 19 newborns were randomly selected after excluding infants with congenital hypothyroidism, low birth weight and premature infants. Neonatal TSH was measured in dried blood spots collected by heel stick 3 to 5 days after birth using the Autodelphia method. Cognitive abilities and psychomotor development were assessed using respectively the Wechsler Preschool and Primary Scale of Intelligence-III and the Charlop-Atwell scale of motor coordination. Psychosocial development was measured using the Child Behavior Check List for ages 1½-5 years. In addition, the mothers completed a self-administered questionnaire in order to account for confounding factors. No association between neonatal TSH within the range of 0 to 15 mIU/L - a surrogate marker for mild iodine deficiency during pregnancy and neurocognitive development was present in Belgian preschool children. The current level of iodine deficiency in Belgium is probably not severe enough to affect the neurodevelopment of children. In this study, we were able to identify several maternal and pregnancy related determinants of neonatal TSH levels. Higher TSH levels were associated with a lifetime (up to child birth) smoking behavior in the mother, a lower weight gain during pregnancy, a longer pregnancy duration. Higher TSH levels were found in spring and winter compared to summer and autumn. It is not advised to use elevated neonatal TSH levels at birth as an indicator of iodine deficiency during late pregnancy without taking potential covariates into account. Given the fact that no association was found between TSH and developmental scores in the children, we cannot evaluate the cut-off point from which we can observe the impairment of children’s neurodevelopment. / Doctorat en Sciences psychologiques et de l'éducation / info:eu-repo/semantics/nonPublished

This paper examines Samuel Richardson's 1740 novel Pamela through two modern models of adolescent development: moral development (Kohlberg and Turiel) and psychosocial development (Erikson, Marcia, and Luyckx et al.). It argues that the novel's eponymous heroine is a complex character who moves beyond the simple stereotypes, being neither a perfect model of feminine virtue nor a coquette on the prowl for a wealthy catch. By examining the developmental arcs Pamela experiences in the novel, it is possible to read her as a typical teenage girl who achieves virtue through errors and growth rather than a static character whose virtue (or simulacrum of it) maintains a flatline.

Researchers explored the relationship among adolescent self-reported amounts of texting and self-esteem, self-construal, autonomy, and attachment. Data were collected from a high school in an urban area in the Mountain West. Participants included 180 students (53% female). Participants were asked to self-describe their volume of texting as high, medium, or low. Participants were also asked to complete the following scales: Rosenberg Self-Esteem Scale, the Self-Construal Scale, the Case Inventory, The Adolescent Autonomy Questionnaire, and The Modified Inventory of Parent and Peer Attachment. It is suggested that text messaging is more strongly related to self-esteem when texting is placed as the dependent variable for both males and females. Results showed that this was the pattern for each variable in question. Results also showed that Cognitive Autonomy mean scores were lower for females on four out of the five subscales of the autonomy measure. This finding was opposite from the mean scores of attachment, which revealed that females tend to have higher parental attachment scores than males.

The college years can be a period of significant identity exploration and development. Data from a longitudinal study of psychosocial development in college and beyond was analyzed to examine the relationship between levels of identity in college and congruence between career plans made in college and later career outcomes, 10 and 20 years after graduation. Results indicated no significant relationship between level of college identity and career congruence, due to the limited variance in level of college identity development. Gender, marital status, and parental status did not influence this relationship. Support is provided for the developmental theory of Emerging Adulthood.

Dissertation (Ed.D.)--Boston University, 1986 / This qualitative study investigated the reasons why American priests resigned their ministries. Two separate analytical lenses were used. One lens included a thematic analysis of reasons for resignation, and a second lens involved a developmental study of the men applying Levinson's psychosocial theory of adult development. Regarding the developmental analysis, the intent of this study was not to confirm or refute Levinson's theory but to understand the development of the sixteen men by applying his theory. Nevertheless, the results of the developmental analysis seemed to support Levinson's postulation of alternating structure-building and structure-changing periods but appeared to question his construct of age-linked periods especially for men in middle adulthood. Although this study supported his reported developmental tasks, it found that the men in the study dealt with some of them at a later age than postulated. Consequently, the writer concluded that Levinson's theory may need to be modified when applying it to men who have committed themselves to a Catholic professional religious life-style. The men developed differently than Levinson's sample because of the unique structure of the institutional Church and priesthood that seemed to delay the men's attainment of responsibility and independence. Several implications and recommendations for further research were suggested. [TRUNCATED]

The purpose of this study was two-fold: First, to qualitatively explore mainstreamed hard of hearing adolescent athletes' psychosocial development, centering on their perspectives of cultural identity, self-concept, and self-esteem and the interaction of these psychological constructs with sport participation. Second, to follow-up with a quantitative measure objectively assessing the impact of sport participation on these psychological domains. Participants were hard of hearing adolescent athletes in the Northeast Atlantic Region, all of whom were currently engaging in some level of sport participation at the time of the study. Five mainstreamed hard of hearing athletes, three male and two female, participated in a semi-structured interview format. Interviews were performed at a time and place convenient for the participant. The purpose of the interview was to elicit detailed, authentic, rich content related to their experiences as hard of hearing athletes both in school and on the field and how these experiences have impacted their self-concept, cultural identification, and social lives. Utilizing grounded theory and adapting the consensual qualitative methods described by Hill, Knox, Thompson, Williams, and Hess (2005), seven conceptual categories and additional sub-categories were derived from the coding process. These conceptual categories and subthemes were found: (a) hearing loss, consisting of severity, age of diagnosis, assistive devices, and familial hearing status, (b) sporting background, sporting initiation, and current team standing, (c) parental roles, consisting of parental support of hearing and parental support of sport, (d) team experience, consisting of teammates, coaches, and opponents, (e) adaptations to being hard of hearing, consisting of working with coaches, on the field and in the classroom, (f) self-esteem/self-concept, consisting of biculturalism, self identity, and on the field mentality, and (g) benefits of sports, consisting of confidence, friends, and other. Participants also completed the Piers-Harris Children's Self-Concept Scale, which provides a total self-concept score and scores across six subscales: physical appearance and attributes, intellectual and school status, happiness and satisfaction, freedom from anxiety, behavioral adjustment, and popularity. All participants scored "average" or "above average" on total self-concept and the six subscales. The population did not consist of enough participants for a quantitative analysis. / Kinesiology

The purpose of this study was to explore the perspectives of academic advising at a tertiary institution in Jamaica and how it has influenced teacher-efficacy and instructional attentiveness among student teachers. The participants included twelve student teachers and four lecturers who have been intimately involved in academic advising. The student teachers selected have been engaged in academic advising for two to four years while the lecturers have been advising for ten to sixteen years. This qualitative study explored how academic advising is related to teacher efficacy and instructional attentiveness among a set of second to fourth year student teachers at a teacher training college in Jamaica. All participants were actively receiving and giving academic advising in a government-owned teacher training institution. The primary source of data was unstructured interviews with student teachers and lecturers. Data were acquired over a two-month period by means of unstructured interviews and field notes. These tools afforded the opportunity to extend the conversations and generate meaning from the responses thereby providing rich descriptive notes of the phenomenon. Data were prepared using triangulation matrices, data coding and the Constant Comparison Approach to generate categories showing patterns and relationships of meaning. The findings on the perspectives of the study participants indicate academic advising has significantly influenced teacher-efficacy among the student teachers as their level of confidence increased, appreciation of teamwork blossomed, instructional competency broadened and misbehaviors controlled. Additionally, their valuing of self and acceptance of other personalities grew immensely which positively affected their relationship with various tiers of staff in the learning environment. The interview data garnered from student teachers indicate that instructional attentiveness improved through the use of multiple teaching methods which included authentic assessment, field experience and student-centered learning. Other factors that boosted instructional attentiveness were good relationships with advisors who were understanding of their differences and commended simple efforts. As a result of the academic advising received, there are several implications for practice and policy which need to be addressed in order to help student teachers to identify their strengths and weaknesses, remain on task, avoid drop out and maintain equilibrium between academic and social experiences as they navigate their way through college. / Educational Leadership
