Informal learning and competence development during a management trainee program

The purpose of this research was to study how management trainee program participants experienced the program with respect to their learning and competence development. Additionally, the purpose was also to examine what the trainees learned and how the learning occurred. Furthermore, factors affecting learning in the workplace were examined. The theoretical framework of this research was formed utilizing individual competence and informal learning frameworks. Research was conducted as a single case study and data was gathered by thematic interviews. The results of this research indicate that the trainees experienced the program as a good method for learning the overall picture of the organization and its business. Regarding competence development, especially knowledge- and cognitive competence categories were developed during the program. The best learning outcomes were achieved through learning by doing, in co-operation with others, and learning from others. The results indicate that the planning of the program and its structure have a significant effect on learning. Furthermore, a sufficient level of challenge was experienced as being important for the quality of the learning as well.

Psychological well-being of the parents and child development, behavior, and quality of life in very low birth weight infants

The parents of premature infants, especially the mothers, are at increased risk for distress. Infants born prematurely are at risk for developmental problems. The aim of this study was to investigate whether the psychological well-being of both parents is associated with child development in very low birth weight (VLBW, ≤1500g) children. The burden of prematurity-related morbidity to the children and to the family was also assessed. A cohort of 201 VLBW infants born during 2001–2006 in the Turku University Hospital, Finland, and their parents were studied (I–IV). One study included a control group (n=166) of full-term infants (IV). The psychological well-being of the parents was evaluated by assessments of depressive symptoms, parenting stress, the sense of coherence and general family functioning. Cognitive, behavioral, and socio-emotional development, and the health-related quality of life (HRQoL) of the children were determined when the children were 2 to 8 years old. The psychological well-being of the parents was associated with the cognitive, behavioral and social development of the VLBW children. The VLBW infants with prematurity-related morbidities had a poorer HRQoL and the general functioning of the family was inferior compared to the control children and their families. 64.5% of the VLBW children survived without morbidities. Most of the VLBW children did not have significant behavior problems (93%), had normal social skills (63%), had no emotional problems (64%), and had no problems in executive functioning (62%). Only 3% of the surviving VLBW infants had significant cognitive delay. In conclusion, the depressive symptoms and stress of the parents can be risk factors for disadvantageous child development, while a strong sense of coherence can be protective. Parents of the premature children with developmental delays might also experience more depressive symptoms and stress than other parents. Prematurity-related morbidities were a burden to the VLBW child as well as to the family.

Cognitive coaching : a multiple case study /

The purpose of this qualitative study was to investigate the application of Cognitive Coaching as a school-based professional development program to improve instructional thought and decision making as well as to enhance staff perceptions, coUegiality and school culture. This topic emerged from personal and professional issues related to the role ofthe reflective practitioner in improving the quality of education, yet cognizant of the fact that little professional development was available to train teachers to become reflective. This case study, positioned within the interpretive sciences, focused on three teachers and how their experiences with cognitive coaching affected their teaching practices. Their knowledge, understanding and use of the four stages of instructional thought (preactive, interactive, reflective and projective) were tested before and at the end of eight coaching cycles, and again after two months to determine whether they had continued to use the reflective process. They were also assessed on whether their attitude towards peer coaching had changed, whether their feelings about teaching had become more positive and whether their professional dialogue had increased. Three methods of data collection were selected to assess growth: interviews, observations and joumaling. Analysis primarily consisted of coding and organizing data according to emerging themes. Although the professed aim of cognitive coaching was to teach the process in order that the teachers would become self-analytical and self-modifying, this study found that the value of the coaching, after trust had been established in both the coach and the process, was in the dialoguing and the time set aside to do it. Once the coaching stopped providing the time to dialogue, to examine one's meanings and beliefs, so did the critical self-reflection. As a result ofthe cognitive coaching experience though, all participants grew in their feelings of efficacy, craftsmanship, flexibility, consciousness and interdependence. The actual and potential significance ofthis study was discussed according to implications for teacher supervision, professional development, school culture, further areas of research and to my personal growth and development.

A comparison of cognitive processes and components of neurological maturation in 3-and-11 year-old children

The relationship between the child's cogni tive development and neurological maturation has been of theoretical interest for many year s. Due to diff iculties such as the lack of sophisticated techniques for measur ing neurolog ical changes and a paucity of normative data, few studies exist that have attempted to correlate the two factors. Recent theory on intellectual development has proposed that neurological maturation may be a factor in the increase of short-term memory storage space. Improved technology has allowed reliable recordings of neurolog ical maturation.. In an attempt to correlate cogni tive development and neurological maturation, this study tested 3-and II-year old children. Fine motor and gross motor short-term memory tests were used to index cogni tive development. Somatosensory evoked potentials elici ted by median nerve stimulation were used to measure the time required for the sensation to pass along the nerve to specific points on the somatosensory pathway. Times were recorded for N14, N20, and P22 interpeak latencies. Maturation of the central nervous system (brain and spinal cord) and the peripheral nervous system (outside the brain and spinal cord) was indi~ated by the recorded times. Signif icant developmental di fferences occurred between 3-and ll-year-olds in memory levels, per ipheral conduction velocity and central conduction times. Linear regression analyses showed that as age increased, memory levels increased and central conduction times decreased. Between the ll-year-old groups, there were no significant differences in central or peripheral nervous system maturation between subjects who achieved a 12 plus score on the digit span test of the WISC-R and those who scored 7 or lower on the same test. Levels achieved on the experimental gross and fine motor short-term memory tests differed significantly within the ll-year-old group.

Social development of primary aged children through a movement education program

Unique in Canada, is a university based movement program offered to children aged 1-12 which is diverse and inclusive in its design to foster healthy physical, cognitive, affective and social development. The purpose of this study is to investigate how children's involvement in a weekly movement education program influences their social development. The primary-aged children involved in this research are participants in the university based Saturday morning program, The Children's Movement Program (CMP), in which creative dance, educational gymnastics and developmental games are employed to enhance optimal development. The 15 participants were systematically observed for 8 weeks as they naturally engaged in the program's activities. Interviews were conducted with both children and their caregivers throughout the duration of the program. Particular attention was paid to the perceptions of caregivers regarding the advantages of a program based upon principles of movement education. Results indicate that participation in the program increases children's opportunity to interact socially and address ways in which program content, pedagogy and context encourage social development. A figure was developed with these components to assist teachers in creating inclusive and meaningful movement experiences. 'Content' is referred to as the material to be learned or the desired outcome for the learner. 'Pedagogy' refers to the process in which the student will engage and 'Context' refers to the environment in which the experience occurs (eg. skating rink with playground balls). It is recommended that each is thoroughly addressed individually for its potential in lesson design.

Families with Children with Autism, Developmental Delay, and Typical Development: The Relationships of Parenting Self-Efficacy, Parenting Strategies, and Child Problem Behaviour

Parents of children with autism spectrum disorders (ASD) and developmental delays (DD) may experience more child problem behaviours, report lower parenting selfefficacy (PSE), and be more reactive than proactive in their parenting strategies than those who have children with typical development (TD). Differences in PSE and parenting strategies may also influence the extent to which child problem behaviours are experienced by parents who have children with ASD and DD, compared to those who have children with TD. Using a convenience sample of parents of children with ASD (n = 48), DD (n = 51), and TD (n = 72), this study examined group differences on three key variables: PSE, parenting strategies, and child problem behaviour. Results indicated that those in the DD group scored lower on PSE in preventing child problem behaviour than the ASD group. The TD group used fewer reactive strategies than the DD group, and fewer proactive strategies than both the ASD and DD groups. For the overall sample, higher reactive strategies use was found to predict higher ratings of child problem behaviour, while a greater proportion of proactive to reactive strategies use predicted lower ratings of child problem behaviour. PSE was found to moderate DD diagnosis and child problem behaviour. Implications for a behavioural (i.e., parenting strategies) or cognitive (i.e., PSE) approach to parenting are discussed.

Early Development of Auditory-Verbal and Visual-Spatial Short-Term Memory: Age and Sex Effects

Memory is a multi-component cognitive ability to retain and retrieve information presented in different modalities. Research on memory development has shown that the memory capacity and the processes improve gradually from early childhood to adolescence. Findings related to the sex-differences in memory abilities in early childhood have been inconsistent. Although previous research has demonstrated the effects of the modality of stimulus presentation (auditory versus verbal) and the type of material to be remembered (visual/spatial versus auditory/verbal) on the memory processes and memory organization, the recent research with children is rather limited. The present study is a secondary analysis of data, originally collected from 530 typically developing Turkish children and adolescents. The purpose of the present study was to examine the age-related developments and sex differences in auditory-verbal and visual-spatial short-term memory (STM) in 177 typically developing male and female children, 5 to 8 years of age. Dot-Locations and Word-Lists from the Children's Memory Scale were used to measure visual-spatial and auditory-verbal STM performances, respectively. The findings of the present study suggest age-related differences in both visual-spatial and auditory-verbal STM. Sex-differences were observed only in one visual-spatial STM subtest performance. Modality comparisons revealed age- and task-related differences between auditory-verbal and visual-spatial STM performances. There were no sex-related effects in terms of modality specific performances. Overall, the results of this study provide evidence of STM development in early childhood, and these effects were mostly independent of sex and the modality of the task.

A Mixed-Method Study of Educator Knowledge and Practice Related to Student Socio-moral Development

The purpose of this study was to explore elementary educators’ knowledge of moral development, how this knowledge relates to their beliefs and sense of efficacy pertaining to character education practices and the socio-moral reasoning of their students. It was hypothesized that educators’ beliefs and practices related to character education would reflect their pedagogy rather than knowledge of moral development theory. It was further hypothesized that there would be differences in student socio-moral reasoning specifically the beliefs and desires that guide actions would differ based on grade and gender. This mixed-method study employing self-report questionnaires, open response vignettes, and semi-structured educator interviews yielded quantitative and qualitative data. Findings indicated socio-moral reasoning of students differed according to grade (age) and gender. Knowledge of moral development theory was found to vary among participants however some practices employed by educators did align with a social cognitive approach to moral development. Significant variables identified consistently among educator and student participants included, autonomy, social competence, sense of school community, and supportiveness. These variables, in conjunction with a sense of fairness, have been identified elsewhere as foundational to moral development (Nucci, 2009), and intrinsic motivation (Ryan & Deci, 2000) and are relevant to educators working to develop student socio-moral reasoning as an aspect of character.

Estime de soi et appropriation cognitive du feedback en contexte d’évaluation de potentiel : le rôle de la valence et de l’influence de la source

L’estime de soi joue un rôle central lorsqu’il est question de prédire les réactions des individus au feedback. En dépit de son influence indéniable sur les réactions des individus au feedback en contexte d’évaluation de potentiel, peu d’études se sont attardées aux facteurs pouvant en atténuer l’effet dans le cadre d’une telle démarche. Cette thèse vise à combler ce manque à travers deux articles empiriques répondant chacun à plusieurs objectifs de recherche. Dans cette optique, des données ont été amassées auprès de deux échantillons indépendants de candidats (étude 1, N = 111; étude 2, N = 153) ayant réalisé une évaluation de potentiel dans une firme-conseil spécialisée en psychologie industrielle. Le premier article vise à tester deux théories relatives à l’estime de soi s’affrontant lorsqu’il est question de prédire les réactions cognitives au feedback, la théorie de l’auto-valorisation et de l’auto-vérification. Pour mieux comprendre ce phénomène, l’influence de l’estime de soi et de la valence décisionnelle du feedback sur les deux composantes de l’appropriation cognitive du feedback en contexte d’évaluation, l’acceptation et la conscientisation, a été testé. Les résultats soutiennent les postulats de la théorie d’auto-valorisation lorsqu’il est question de prédire l’acceptation du feedback. En contrepartie, les résultats offrent peu de soutien à la théorie de l’auto-vérification dans la prédiction de la conscientisation à l’égard du feedback. Le second article vise à identifier des leviers modulables pour influencer favorablement les réactions des individus ayant une plus faible estime d’eux-mêmes. Pour ce faire, deux variables relatives à l’influence de la source ont été ciblées, la crédibilité perçue et les pratiques de confrontation constructive. Cet article comprend deux études, soit une première ayant pour objectif de valider un instrument mesurant la crédibilité perçue de la source et une seconde examinant les relations entre trois déterminants, soit l’estime de soi du candidat, la crédibilité perçue de la source et les pratiques de confrontation constructive, et deux réactions cognitives au feedback, l’acceptation et la conscientisation. Les analyses de la première étude font ressortir que l’échelle de crédibilité perçue présente des qualités psychométriques satisfaisantes et les résultats corroborent une structure unifactorielle. Les résultats de la seconde étude indiquent que les trois déterminants étudiés sont positivement reliés à l’acceptation et à la conscientisation. Les effets d’interaction significatifs font ressortir des conditions favorisant l’acceptation et la conscientisation chez les individus ayant une plus faible estime d’eux-mêmes. La crédibilité perçue atténue la relation entre l’estime de soi et l’acceptation alors que la confrontation constructive modère les relations entre l’estime de soi et, tant l’acceptation que la conscientisation. Enfin, la crédibilité perçue et la confrontation constructive interagissent dans la prédiction de la conscientisation, faisant ainsi ressortir l’importance d’établir sa crédibilité pour augmenter l’effet positif de la confrontation constructive. Les apports théorique et conceptuel de chacun des articles ainsi que les pistes d’intervention pratiques en découlant sont discutés séparément et repris dans une conclusion globale. Les retombées de cette thèse, tant sur le plan de la recherche que de l'intervention, sont également abordées dans cette dernière section.

L'épilepsie bénigne à pointes centrotemporales : investigation cognitive et études en imagerie fonctionnelle et structurelle.

L’épilepsie bénigne à pointes centrotemporales (EPCT) est la forme la plus fréquente des épilepsies idiopathiques chez l’enfant (Fastenau et al., 2009). Le pronostic de ces patients est bon, notamment en raison de la rémission spontanée de cette épilepsie à l’adolescence; toutefois plusieurs études suggèrent la présence de troubles cognitifs et de spécificités neuroanatomiques. Il n’existe pas actuellement de consensus sur les liens entre leurs troubles cognitifs et leurs particularités neuroanatomiques et neurofonctionnelles. Dans cette thèse, notre but est de préciser le profil des enfants ayant une épilepsie bénigne à pointes centro-temporales, en investiguant les caractéristiques des patients à plusieurs niveaux: cognitif, fonctionnel, structurel. La thèse est composée de quatre articles, dont deux articles empiriques. Notre premier article a pour objectif de recenser les difficultés cognitives et affectives rapportées par les études s’intéressant aux caractéristiques des enfants ayant une épilepsie bénigne. Bien qu’une certaine variabilité soit retrouvée dans la littérature, cette revue démontre qu’une histoire d’épilepsie, même bénigne, peut être un facteur de risque pour le développement cognitif et socio-affectif des enfants. Notre revue de littérature a indiqué des troubles particuliers du langage chez ces enfants, mais aucune étude n’avait auparavant investigué spécifiquement la compréhension de lecture chez les enfants ayant une EPCT, une compétence essentielle dans le cheminement scolaire des enfants. Ainsi, nous avons développé une tâche novatrice de compréhension de lecture de phrases en imagerie par résonnance magnétique fonctionnelle (IRMf), adaptée à la population pédiatrique. Dans notre second article, nous avons validé cette tâche auprès d’enfants sains et nous avons mis en évidence une mobilisation des régions cérébrales généralement engagées dans des tâches langagières chez l’enfant sain, y compris les régions impliquées dans le traitement sémantique (Berl et al., 2010; Blumenfeld, Booth et Burman, 2006). Le troisième article de cette thèse rapporte notre investigation du réseau cérébral activé durant cette nouvelle tâche de compréhension de lecture de phrases en IRMf chez les enfants ayant une EPCT. Nos résultats suggèrent que ces derniers ont recours à l’activation d’un réseau cérébral plus large, présentant des similarités avec celui retrouvé chez les enfants dyslexiques. Par ailleurs, l’activation du striatum gauche, structure généralement associée à la réalisation de processus cognitifs complexes est uniquement retrouvée chez les enfants épileptiques. Étant donné que les enfants ayant une EPCT obtiennent des performances à la tâche d’IRMf équivalentes à celles des enfants sains, il est possible d’émettre l’hypothèse que ces différences d’activations cérébrales soient adaptatives. L’étude des relations entre les résultats neuropsychologiques, la performance à la tâche et les activations cérébrales a mis en évidence des prédicteurs différents entre les deux groupes d’enfants, suggérant qu’ils ne s’appuient pas exactement sur les mêmes processus cognitifs pour réussir la tâche. De plus, nous avons réalisé un travail d’intégration des diverses méthodologies utilisées dans les études en imagerie pondérée en diffusion chez l’enfant épileptique, ce qui constitue le quatrième article de cette thèse. Nous rapportons les diverses applications de cette méthode dans la caractérisation des anomalies structurelles subtiles de la matière blanche chez les enfants épileptiques en général. Les différentes méthodologies employées, les enjeux, et les biais potentiels relatifs aux traitements des données de diffusion y sont discutés. Enfin, pour mieux comprendre l’origine et les marqueurs de cette épilepsie, nous avons étudié les spécificités structurelles des cerveaux des enfants ayant une EPCT à l’aide d’analyses sur les données d’imagerie par résonnance magnétique. Aucune différence n’a été mise en évidence au niveau de la matière grise entre les cerveaux d’enfants sains et ceux ayant une EPCT. À l’inverse, nous rapportons des différences subtiles au niveau de la matière blanche dans notre population d’enfants épileptiques, avec une diminution de l’anisotropie fractionnelle (FA) au niveau temporal inférieur/moyen de l’hémisphère gauche, ainsi que dans l’hémisphère droit dans les régions frontales moyennes et occipitales inférieures. Ces résultats suggèrent la présence d’altérations de la matière blanche subtiles et diffuses dans le cerveau des enfants ayant une EPCT et concordent avec ceux d’autres études récentes (Ciumas et al., 2014).

Design and Development of re configurable compact cross patch antenna for switchable polarization

Antennas are necessary and vital components of communication and radar systems, but sometimes their inability to adjust to new operating scenarios can limit system performance. Reconfigurable antennas can adjust with changing system requirements or environmental conditions and provide additional levels of functionality that may result in wider instantaneous frequency bandwidths, more extensive scan volumes, and radiation patterns with more desirable side lobe distributions. Their agility and diversity created new horizons for different types of applications especially in cognitive radio, Multiple Input Multiple Output Systems, satellites and many other applications. Reconfigurable antennas satisfy the requirements for increased functionality, such as direction finding, beam steering, radar, control and command, within a confined volume. The intelligence associated with the reconfigurable antennas revolved around switching mechanisms utilized. In the present work, we have investigated frequency reconfigurable polarization diversity antennas using two methods: 1. By using low-loss, high-isolation switches such as PIN diode, the antenna can be structurally reconfigured to maintain the elements near their resonant dimensions for different frequency bands and/or polarization. 2. Secondly, the incorporation of variable capacitors or varactors, to overcome many problems faced in using switches and their biasing. The performances of these designs have been studied using standard simulation tools used in industry/academia and they have been experimentally verified. Antenna design guidelines are also deduced by accounting the resonances. One of the major contributions of the thesis lies in the analysis of the designed antennas using FDTD based numerical computation to validate their performance.

Normative and cognitive influences on female entrepreneurial reluctance at the base of the pyramid - an explorative study of cleaning ladies in Istanbul

Previous research has considered entrepreneurship as a way out of poverty and as a chance to foster economic growth. Moreover, specifically start-ups headed by women have played an important role in the economic development and it has been argued that gender-related issues, amongst others, play a significant role for the performance of a country or region. Against this background, this qualitative study explores desires, reluctances and constraints toward entrepreneurial activities of a comparably homogenous group of potential (poor) entrepreneurs in an emerging economy—cleaning ladies in Istanbul. We focus on this particular context as still rather little is known on reasons why women do not start a business (in Turkey). We believe exploring the reasons why certain individuals choose not to become entrepreneurs is at least as telling as investigating why they do so. We draw upon the social dimensions of entrepreneurship by Shapero and Sokol (1982) alongside Institutional Theory and posit that normative and cognitive forces may shape individual decisions on entrepreneurship. We identified two basic clusters of women and discuss possible hindrance factors undermining entrepreneurial desires and limitations for entrepreneurship as well as possible avenues for policy makers (and MNCs) to foster entrepreneurship in the given community.

Double burden malnutrition of preschool children and its association with brain development and milk consumption

Protecting the quality of children growth and development becomes a supreme qualification for the betterment of a nation. Double burden child malnutrition is emerging worldwide which might have a strong influence to the quality of child brain development and could not be paid-off on later life. Milk places a notable portion during the infancy and childhood. Thus, the deep insight on milk consumption pattern might explain the phenomenon of double burden child malnutrition correlated to the cognitive impairments. Objective: Current study is intended (1) to examine the current face of Indonesian double burden child malnutrition: a case study in Bogor, West Java, Indonesia, (2) to investigate the association of this phenomenon with child brain development, and (3) to examine the contribution of socioeconomic status and milk consumption on this phenomenon so that able to formulate some possible solutions to encounter this problem. Design: A cross-sectional study using a structured coded questionnaire was conducted among 387 children age 5-6 years old and their parents from 8 areas in Bogor, West-Java, Indonesia on November 2012 to December 2013, to record some socioeconomic status, anthropometric measurements, and history of breast feeding. Diet and probability of milk intake was assessed by two 24 h dietary recalls and food frequency questionnaire (FFQ). Usual daily milk intake was calculated using Multiple Source Method (MSM). Some brain development indicators (IQ, EQ, learning, and memory ability) using Projective Multi-phase Orientation method was also executed to learn the correlation between double burden child malnutrition and some brain development indicator. Results and conclusions: A small picture of child double burden malnutrition is shown in Bogor, West Java, Indonesia, where prevalence of Severe Acute Malnutrition (SAM) is 27.1%, Moderate Acute Malnutrition (MAM) is 24.9%, and overnutrition is 7.7%. This phenomenon proves to impair the child brain development. The malnourished children, both under- and over- nourished children have significantly (P-value<0.05) lower memory ability compared to the normal children (memory score, N; SAM = 45.2, 60; MAM = 48.5, 61; overweight = 48.4, 43; obesity = 47.9, 60; normal = 52.4, 163). The plausible reasons behind these evidences are the lack of nutrient intake during the sprout growth period on undernourished children or increasing adiposity on overnourished children might influence the growth of hippocampus area which responsible to the memory ability. Either undernutrition or overnutrition, the preventive action on this problem is preferable to avoid ongoing cognitive performance loss of the next generation. Some possible solutions for this phenomenon are promoting breast feeding initiation and exclusive breast feeding practices for infants, supporting the consumption of a normal portion of milk (250 to 500 ml per day) for children, and breaking the chain of poverty by socioeconomic improvement. And, the national food security becomes the fundamental point for the betterment of the next. In the global context, the causes of under- and over- nutrition have to be opposed through integrated and systemic approaches for a better quality of the next generation of human beings.

"Functional Upregulation of Ca2+ -Activated K+ Channels in the Development of Substantia Nigra Dopamine Neurons"

Many connections in the basal ganglia are made around birth when animals are exposed to a host of new affective, cognitive, and sensori-motor stimuli. It is thought that dopamine modulates cortico-striatal synapses that result in the strengthening of those connections that lead to desired outcomes. We propose that there must be a time before which stimuli cannot be processed into functional connections, otherwise it would imply an effective link between stimulus, response, and reward in uterus. Consistent with these ideas, we present evidence that early in development dopamine neurons are electrically immature and do not produce high-frequency firing in response to salient stimuli. We ask first, what makes dopamine neurons immature? and second, what are the implications of this immaturity for the basal ganglia? As an answer to the first question, we find that at birth the outward current is small (3nS-V), insensitive to Ca2z, TEA, BK, and SK blockers. Rapidly after birth, the outward current increases to 15nS-V and becomes sensitive to Ca2z, TEA, BK, and SK blockers. We make a detailed analysis of the kinetics of the components of the outward currents and produce a model for BK and SK channels that we use to reproduce the outward current, and to infer the geometrical arrangement of BK and Ca2z channels in clusters. In the first cluster, T-type Ca2z and BK channels are coupled within distances of *20 nm (200 A˚). The second cluster consists of L-type Ca2z and BK channels that are spread over distances of at least 60 nm. As for the second question, we propose that early in development, the mechanism of action selection is in a ‘‘locked-in’’ state that would prevent dopamine neurons from reinforcing cortico-striatal synapses that do not have a functional experiential- based value.
