Ethington, Kalene Mears. "Developmental Stages Associated with Organizational Learning: An Instrument Development Study." BYU ScholarsArchive, 2019. https://scholarsarchive.byu.edu/etd/8287.
Full textAbstract:
Background: Previous research has identified four distinct developmental stages associated with organizational learning in high-performing hospital units: identity and ownership, team and respect, accountability and support, and reliability and sustainability. We designed a research instrument to measure these constructs. The purpose of this thesis was to establish the content and predictive validity of this instrument.Methods: The Organizational Learning Development Instrument (OLDI) consists of a total of 35 items in Likert-scale format. Item-level and instrument-level content validity were assessed using three cycles of cognitive interviewing with 28 nurses, and eight expert ratings. The OLDI was administered to nurses in Magnet® hospitals via a web-based survey. National Database of Nursing Quality Indicators (NDNQI) and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) reports were used for comparison of hospital performance. Predictive validity was tested using multiple linear regression. Based on a power analysis for multiple linear regression, reaching 80% power, with a medium effect size of 0.15, an alpha of 0.05, and five predictor variables, the target sample size was 92 hospital units.Results: Results from 63 inpatient units in 11 Magnet® hospitals were used. The scale- level content validity for this instrument was 0.95 and item-level content validity index scores ranged from 0.86 to 1.0, suggesting excellent content validity. No significant relationships were found between OLDI results and NDNQI measures. Significant correlations (P<.05) were found between several OLDI constructs and HCAHPS composites.Discussion: Correlations with HCAHPS scores help validate the OLDI, as well as the theory underlying the instrument. The OLDI may not have predicted NDNQI measures due to a lack of instrument sensitivity or because NDNQI results are strongly influenced by other factors. Nurse managers can use the OLDI to predict unit performance related to patient satisfaction and to determine actions that may improve unit performance. Replicating this study with a larger sample size and more diverse hospital performance and more uniform unit type could further validate this instrument.

Turner, Kara Jane. "Telomere length and distribution in three developmental stages." Thesis, University of Kent, 2015. https://kar.kent.ac.uk/47463/.
Full textAbstract:
Telomeres are specialised nucleoprotein structures present at the ends of each chromatid that function to maintain genome stability. It is well established that a gradual decline in telomere length is associated with the process of cellular ageing, and thereby to the pathobiology of age-related diseases. In addition, the localisation of the telomere at the nuclear periphery plays an important role in the spatio-temporal organisation of the genome and in ensuring faithful segregation of chromosomes during meiosis. The aims of this thesis were to investigate telomere localisation in the nucleus, and telomere length in three hitherto early stages of development, gametogenesis, preimplantation embryogenesis and the neonatal period. Specifically: 1. To test the hypothesis that telomeres localised at the nuclear periphery in sperm cells and that this organisation was altered in sub-fertile men 2. To optimise a means of assessing average telomere length using DNA from small sample sizes and using whole genome amplified DNA from single cells 3. To investigate the role of telomere length in reproductive ageing and aneuploidy generation in women by testing the hypothesis that telomere length is significantly shorter in the first polar bodies and cleavage stage embryos of older women 4. To test the hypothesis that “preterm at term” babies (i.e. premature babies assessed at the time of their due date) displayed genetic signs of premature ageing (as manifested by significantly shorter telomeres than their term born counterparts) alongside the already established clinical signs (characterised by hypertension, diabetes and altered body fat distribution) Results confirmed the peripheral distribution of telomeres in the sperm heads of normally fertile males (using both 2D and 3D imaging) plus the novel finding that telomere distribution patterns are altered in the sperm heads of infertile males. Secondly, a reliable means of measuring telomere length was optimised in order to assess average telomere length using DNA from small sample volumes (down to single cells). Using this technology, average telomere length analysis in polar bodies and embryos found no evidence to support the hypothesis that telomere length is associated with either advanced maternal age or aneuploidy generation. Similarly, results suggest that telomere length is not significantly shorter in “preterm at term” infants compared to term born controls, thus providing no evidence that telomere attrition is involved in the pathobiology of the ‘aged phenotype’ observed in preterm infants. Taken together, results from this thesis provide some novel insights into the function of these highly important features of the genome, but also highlight that a great deal remains to be uncovered in the complex molecular mechanisms that contribute to the regulation of telomere length and nuclear distribution.

Parent, Justin. "Multidimenional Assessment Of Parenting Across Three Developmental Stages." ScholarWorks @ UVM, 2017. http://scholarworks.uvm.edu/graddis/613.
Full textAbstract:
BACKGROUND: The primary aim of the current study was to create a new measure of parenting practices, constituted by items from already established measures in order to advance the measurement of parenting practices in clinical and research settings. The current study utilized five stages designed to select only the best parenting items, establish a factor structure consisting of positive and negative dimensions of parenting, meaningfully consider child developmental stage, ensure strong psychometric properties, and provide initial evidence for the validity of the final measure.
METHODS: A total of 1,790 parents (44% fathers) were recruited online through Amazon's Mechanical Turk for three cohorts: Stages 1 (N = 611), 2 (N = 615), and 3 (N = 564). Each sample was equally divided by child developmental stage: Young childhood (3 to 7 years old), middle childhood (8 to 12 years old), and adolescence (13 to 17 years old). Parenting items were selected and adapted from several well-established parenting scales. Measure development followed five rigorous stages using separate samples for each set of factor analyses as advocated by methodologists. Advanced statistical methods were employed for determining final factor structure (e.g., exploratory structural equation modeling - ESEM) and reliability (omega coefficient; longitudinal ESEM), as well as providing initial support for validity (e.g., latent curve modeling - LCM).
RESULTS: Through a five-stage empirical approach, the Multidimensional Assessment of Parenting Scale (MAPS) was developed, successfully achieving all aims. The MAPS factor structure included both positive and negative dimensions of warmth/hostility and behavioral control that were appropriate for parents of children across the developmental span. Seven out of eight MAPS subscales demonstrated excellent reliability (above .80). LCM analyses provided initial support for the validity of all MAPS subscales.
DISCUSSION: Although the stages of the current study embody an empirical approach to scale development, it also has important theoretical aspects. The factor structure of the MAPS updates prior the theoretical conceptualization of parenting practices (Schaefer, 1959) in order to inform new research and applications. Future directions are discussed.

Full textAbstract:
The Norway spruce Picea abies is an economically important export to the Swedish economy. There are a number of environmental and endogenous factors that impact the generation time of this species meaning that it can take 20-25 years for a tree to mature. The long generation time creates a challenge for plant breeding programs in terms of how genetic mechanisms are able to be studied as well as how quickly trees can be produced for lumber. The characterization of gene expression patterns in the context of special tissue domains is essential to understanding the underlying functions behind complex biological systems and in the case of P. abies may prove more crucial to determining the activation of genes at specific reproductive growth points. There are several techniques available for the analysis of spatial expression profiles, however, the unique high throughput nature coupled to the morphological information provided by Spatial Transcriptomics creates new opportunities for exploratory analysis. Spatial Transcriptomics offers a distinct approach to answering fundamental questions about the genetic mechanisms that regulate reproductive phase change and cone-setting in conifers. This study focuses on spatial gene expression analysis and the integration of de novo transcriptome assembly contigs to confirm the spatial context of putatively discovered genes such as DAL1, DAL2, DAL3, and DAL10 from previous studies and to potentially localize transcripts that could not previously be identified due to the inability to obtain complete transcripts. The aim is to create a workflow to identify genes that contribute to the growth patterns in the naturally occurring acrocona mutant that could prove useful to improving tree breeding programs.

Mounla, Najwa. "Developmental Stages of Preschool Teachers in Selected Arab Gulf Countries." DigitalCommons@USU, 1996. https://digitalcommons.usu.edu/etd/2395.
Full textAbstract:
The current study focused on examining the developmental stages of preschool teachers in the Arab Gulf region. Specifically, the needs and concerns of teachers were investigated using a pretest/posttest (12-month interval) design. Participants included two greoups of preschool teachers, trained (n= 35) and untrained (n=122)
Contrary to expectations, the sequential nature of development stages of teachers did not emerge. Instead, the results showed that teachers become less concerned about teaching as they progress in their careers.
When data from the present study were factor-analyzed they yielded only two areas of concerns that seemed applicable cross-cultrally. When data were subjected to analysis of variance, results revealed that training had a significant main effect on teaching concerns while teaching experience did not. Further exploration of the category experience showed that, for Factor II, the trained group of teachers had a larger drop in their level of teaching concerns than the untrained group. This was especially evident with two subgroups, low (1 to 3) years of teaching experience and high (8 to 16) years of teaching experience. The trained group with medium (4 to 7) years of teaching experience maintained a consistently low score on both pretest and posttest. Teaching experience for Factor II appears to have a main effect in reducing the level of concerns of teachers over their teaching. This was especially evident between pretest and posttest for the low-and high-experience trained teachers.

Burgess, Debra Ann Paton. "Effects of adult developmental stages on the professional education of teachers." Scholarly Commons, 1995. https://scholarlycommons.pacific.edu/uop_etds/2482.
Full textAbstract:
The purpose of this study was to examine the stages of teaching careers and staff development preferences within the context of Levinson's (1978) adult development theory. This study found that adult development theory affects teachers' view of their careers and identified four themes across the teaching career: isolation, low perceived status, student relationships, and support networks. Additionally, this study describes what constitutes sound staff development activities. Semi structured group and individual interviews were used to collect data from 31 practicing elementary teachers in two rural northern California schools districts. The sample was selected from autobiographical and professional data questionnaire completed by 159 teachers. Grounded theory was used to analyze data and integrate into a description of teaching careers that spans a range of 30+ years of experience. Four teacher career stages were identified: early, early middle, late middle and veteran. The four themes identified in this study were constant across the teaching career, but the significance varied at each developmental stage. Results supported a differentiated model of staff development based on teacher career stages. A career long, articulated model of teacher staff development was developed, incorporating adult learning principles, reflective practice, and the role of mentor at each career stage. The recommended model in this study focuses on the needs of the teacher at each career stage and views the teacher as a fully, functioning professional. Thus, a major conclusion in this study is the need for a paradigm shift in current staff development practices that focuses on teacher rather than institutional or societal needs. Schon's (1983, 1987) model of reflective practice of conscious reflection before, during and after practice is described to promote teacher growth at each developmental career stage. Finally, this study concludes that support networks are a vital element in teacher professional development and describes the changing role of the mentor throughout the career cycle to assist in the professional growth of the individual teacher.

Full textAbstract:
The purpose of this study was to determine the impact of child-centered play therapy on children of Piaget's preoperational and concrete operations developmental stages. Piaget's assertions about the contributions of play to cognitive, affective, and social development have provided a basis for the theoretical rationale for the use of play as a therapeutic intervention. The impact of child-centered play therapy was measured by a decrease in parent-child relationship stress as measured by scores on the Child Domain, Parent Domain, and Total Stress Score of the Parenting Stress Index. This study utilized a three wave repeated measures ANOVA design to analyze the impact of child-centered play therapy on children between the ages of 3-8 who received 19-23 individual child-centered play therapy sessions. A pretest, approximate midpoint, and posttest administration was collected for use in the analysis. The population study comprised 24 children referred to the Child and Family Resource Clinic on the University of North Texas campus. Participating children were divided into two treatment groups based on their age at the time of treatment. The preoperational development treatment group consisted of 12 children aged of 3-6 years and the concrete operations development treatment group consisted of children aged 7-8 years. Nine hypotheses were tested using three wave repeated measures ANOVA and eta squared. The results of this study tentatively support the impact of child-centered play therapy with children of both the preoperational and concrete operations developmental stages. The data indicates a statistically significant difference in the impact of child-centered play therapy for children of different developmental stages.

Full textAbstract:
The aim of this thesis was to assess immune function in developmental stages of the marine mussel, Mytilus edulis. Light and electron microscopy studies were carried out to examine haemocytes of larval, postlarval and adult mussels. The susceptibility of both larval and postlarval mussels to several common marine bacteria were examined. Three species of bacteria that have been linked with disease outbreaks were studied; namely Vibrio tubiashii, Vibrio alginolyticus and Alteromonas haloplanktis. Interactive effects of pollutants (copper and phenanthrene) and food availability on the susceptibility of postlarvae to bacteria was also examined. In summary, it was found that larval M. edulis were more susceptible to the bacteria examined than postlarvae. The susceptibility of postlarvae to bacteria altered with the introduction of stressors. Food deprivation and co-exposure to phenanthrene increased the susceptibility of postlarvae to V tubiashii. However, co-exposure to copper decreased the susceptibility of the postlarvae to V tubiashii. There were shown to be strong seasonal effects that further altered the susceptibility of postlarvae to bacteria, these effects were thought to be due to nutritional status of the postlarvae as opposed to reproductive effects as the postlarvae were reproductively immature. The ontogeny of M. edulis haemocytes was examined. Blood cells were not detected in electron micrographs of D-shell larvae but were identified in both in situ in postlarval sections processed for electron microscopy as well as in haemolymph samples taken from postlarvae. A previously undescribed blood cell type was reported in postlarvae, lending support to the model put forward by Mix (1976) stating that all mussel haemocytes derive from a single cell line.

Full textAbstract:
The present study applies early field experience theory and developmental stages theory as the basis of teacher training i n a junior college program in Taiwan. Two hundred sixty-six junior college students from two junior colleges were surveyed in order to ascertain what factors had an effect on the concept of teaching concerns. Comparisons were made among the following : with/ without preschool education background in senior high school, grade, school, age, fathers' educational levels, mothers' educational levels, and fathers' yearly income. The results indicate that early field experiences had a direct effect on teaching concerns. The students' year of study (freshmen vs sophomore) in junior college made a difference depending on whether they had been exposed to an early field experience. The groups that had a preschool education background had higher mean developmental-teaching-stage scores, in first (freshmen) study year, but lower mean scores in the second (sophomore) study year. The mean developmentalteaching- stage scores for both study years of junior college students with preschool education background were very close to each other. Junior college students without a preschool education background in senior high had a higher mean developmental-teaching-stage score in the second year than in the first year.

Full textAbstract:
<p>An individual's financial position of dependence or independence can impact a person's state of psychological well-being and his/her level of functioning in society. Being financially independent can provide a sense of security and empower an individual to increase their quality of life. However, being financially dependent on others can create a hardship of fear and uncertainty about how to feed one's family or pay the rent. A number of published studies (Kruttschnitt, 1982; Natalier, 2007; Powles, 1991; Rogers, 2004; Schneider, 2000; Strube & Barbour, 1983) have been performed for specific topics related to financial dependency; however, the various developmental stages people experience when they are financially independent or financially dependent has not yet been researched or characterized. The goals of this study are: 1) to examine and identify the developmental stages of financial dependence and independence that individuals experience over the life span, and 2) to determine the benefits and challenges people encounter as a result of experiencing each of these stages of financial dependence and independence. Gaining a greater understanding of the common experiences people have in each of these states of financial dependence and independence will enable psychology and sociology professionals to better recognize the needs and concerns of their clients.

Full textAbstract:
The purposes of this study were to determine if a kindergartener's developmental stage correlates with subsequent scholastic achievement, to determine whether developmentally younger children who repeat kindergarten attain higher academic achievement than developmental 1y younger children who do not repeat kindergarten, and to investigate the relationship between head circumference, developmental age, and achievement. Ninety-seven kindergartners of various ethnicity and socio-economic status were administered the Gesell School Readiness Screening Test to determine developmental age and were followed academically for three years. Head circumference was noted periodically to measure brain growth. The hypotheses predicted significant positive correlations between developmental age in kindergarten and scores on later achievement tests. Further, it was predicted that children below 5.3 years in developmental age who delayed entrance to first grade would score significantly higher on first grade achievement tests than match-paired promoted students. It was hypothesized that there would be significant correlations between head circumference growth and (a) gains in achievement test scores and (b) developmental age at kindergarten. The first hypothesis, tested by Pearson Product Moment Correlations, established the existence of significant correlations between developmental ages of test subjects and their scores on four academic achievement tests. The results indicated that developmental age was a better predictor of achievement test scores than chronological age. Since only five children in this study were retained in kindergarten, hypothesis 2 was analyzed descriptively. Mean scores on first grade achievement tests were higher for the retainees than for the "at risk" non-retainees. Hypothesis 3 was tested by stepwise multiple regression. At the first step, the linear trend between the independent variable, CTBS score, and the dependent variable, I TBS score, was calculated and found to be significant at the .001 level. The addition of head circumference growth to the equation did not add significantly to the prediction of I TBS scores from CTBS scores. There was a significant negative correlation between developmental age in kindergarten and head growth.

Full textAbstract:
The psychometric properties of a parent-completed developmental questionnaire for children at 6 years of age were investigated. Currently, few developmental screening instruments for 6-year-old children have been validated, and most available instruments are designed to be completed by teachers or professionals, who may not witness an optimal sample of child behavior. Thus a screening tool with robust psychometric properties is needed that can be completed by parents or caregivers who see the child across settings and time. A total of 169 children participated in this research. Data collection included online and paper completion during well child visits, in clinics, at preschool programs, and in parents' homes. A random subsample was asked to participate in reliability and convergent validity studies. Cronbach's alpha coefficient was used to measure internal consistency reliability. Results indicated a Cronbach alpha of agreement with the Child Development Inventory was used. A Confirmatory Factor Analysis with categorical data confirmed the 6-Year Ages and Stages Questionnaire domains, e.g., communication, personal social, fine motor, gross motor, and problem solving. Limitations of the current study and directions for future research are discussed.<br>10000-01-01

Toxic effects of the pesticide Lindane on the eggs, yolksac fry and larvae of the fathead minnow (Pimephales promelas) were investigated over 14 days at 25 and 18°C. The general objective was to understand the effects of the pesticide on the early life stages of the fish, and to evaluate the suitability of these stages as indicators of contaminated environments.
Egg, yolk-sac and larval stages that had been exposed to 300, 120, 90, 60, 30, 10, 5, and 0 μg/L of Lindane at 25°C exhibited a 14d-LC₅₀ of 44 μg/L. Similarly, the same stages exposed to 300, 120, 90, 60, 30, 10, and 0 μg/L of Lindane at 18°C exhibited a 14d-LC₅₀ of 37 μg/L. Lower temperature thus seemed to increase the susceptibility of the fish to the pesticide.
Mortality data were also used to determine the sensitivity of the early developmental stages of fish to the pesticide. At 25°C, the larval stage was the most sensitive stage. At 18°C, on the other hand, the most sensitive stage was the yolk-sac. Results obtained from experiments in which Lindane doses were applied at different intervals within the 14d-period supported these observations.
Low temperatures had a marked effect on the sensitivity of the fathead minnow to Lindane. Embryos exposed to Lindane at 18°C showed different temporal distribution of mortality than those at 25°C. A delay in hatching and emergence of smaller larvae were also noted at 18°C.
Lordoscoliosis, edemas and hemorrhages were the most common morphological changes induced by the pesticide during the larval stage. The frequency of these abnormalities was linearly related to doses of Lindane. Impaired swimming behavior was also noted, but it was not related to dosages.<br>Master of Science

The Chinese government has announced the 2013 Guidelines for developing a national system for early detection of disability among children under 6 years of age. However, given limited resources, challenges exist with developmental measures required in the 2013 Guidelines. In order to meet the needs for a more accurate and cost-efficient measure for developmental assessment, the Ages & Stages Questionnaires:INVENTORY was translated into Simplified Chinese, and validated on a regional sample of 812 Chinese children ages from 1-25 months. Psychometric properties were examined; data from previous studies on the ASQ:INVENTORY in the U.S. were compared to identify differences between the two countries. Results indicated that the Chinese ASQ:INVENTORY was an instrument with sufficient internal consistency, reliability and validity. It was well accepted by parents and professionals in China. Findings suggested that the Chinese ASQ:INVENTORY provides a promising alternative measure for screening and diagnosing developmental delays in young children in China. Implications for future research and implementation are discussed.

Full textAbstract:
Two accessions of tepary (phaseolus acutifolius Gray var. latifolius) and navy (P. vulgaris L. 'Fleetwood') beans were studied for salt tolerance at several• developmental stages. Genotypes were germinated at 0.0 through -2.5 MPa NaCl at 25°C and 35°C for nine days. Tepary accessions had higher germination percentages and rates than navy for ≤ - 2.0 MPa at 250C and ≤ - 1.5 MPa at 35°C. Fresh weights of root plus hypocotyl decreased severely with the first increment of NaCl (-0.5 MPa) for all genotypes. Fresh weight of navy was reduced more at 35°C than at 25°C. Genotypes were stressed in vermiculite-filled trays with 0.0 through -1.5 MPa NaCl for 14 days. Final growth stage and rates of emergence were reduced at salinities ~ -0.6 MPa NaCl, and were higher in tepary than navy at -1.2 MPa. Tepary beans tended to maintain higher water and osmotic potentials, and at -0.9 MPa had less reduction in leaf area than navy beans. Fresh weights, dry weights and root:shoot ratios declined in all genotypes with increasing salinities. Plants grown hydroponically were stressed with -0.10, -0.25, and -0.50 MPa NaCl during either vegetative or reproductive stages. Navy had equal or greater fresh and dry weights of leaf, stem, and pods at -0.10 MPa, but tepary beans had equal or greater weights at the highest salinity relative to navy. Tepary had the greatest pod weight with -0.50 MPa NaCl applied during the reproductive stage. Carbon exchange rates (CER) were lower in navy than one or both tepary beans at some sampling times. Tepary beans tended to have higher leaf water and osmotic potentials than did navy. Transpiration and stomatal resistance values were similar in all genotypes, while leaf temperatures were different in white tepary versus navy. Tepary beans yielded higher than navy when grown in low and high salinity fields. Transpiration rates, leaf water and osmotic potentials, and CERs were similar or higher, while stomatal resistance and leaf temperatures were similar or lower in tepary than in navy. Plant height and stand count also were measured. Tepary was more salt tolerant than navy, exhibiting greater tolerance to NaCl at every growth stage.

Full textAbstract:
Nitrogen (N) is present in proteins, enzymes, cell structures, purines and pyrimidines in DNA and RNA molecules, photosynthetic pigments, and several other types of molecules in all living organisms. Nonetheless, even though N makes up more than 78% of the atmosphere, it is reported to be the most frequent deficient nutrient in plants. Nitrate (NO3-) and ammonium (NH4+) are the N forms absorbed by plants from soil, but legume crops can establish symbiotic relationships with rhizobia bacteria, and fix N2 from the atmosphere. In soybean, increasing yield and protein content are raising the crop's N requirement; therefore, enhanced N2 fixation is seen as a reliable path to avoid the use of N fertilizers. In this study, the objective was to perform a comprehensive screening in greenhouse and field conditions of soybean genotypes for traits related to N2 fixation. The purpose was to identify among the soybean genotypes different N2 fixation profiles at early and late stages, as well as to investigate their capacity to accumulate above-ground N and supply carry-over N to following crops. The results showed different profiles among the soybean genotypes for early and late N2 fixation capacity, both in greenhouse and field evaluations. Different traits were correlated to either early or late N2 fixation activity. Soybean and winter-rye shoot dry mass were evaluated in the field to assess above-ground N accumulation and carry-over N, respectively. Soybean genotypes were identified with specific capacities to accumulate N in above-ground biomass or supply N to winter-rye. The patterns of N2 fixation identified in this study, as well as the different abilities to accumulate N above-ground or supply N to following crops, could assist in the selection of superior lines with improved N2 fixation capacity.

Full textAbstract:
Dans le contexte du changement global, la diminution de la disponibilité en oxygène (hypoxie) combinée à la hausse de la température sont deux phénomènes particulièrement présents dans les eaux côtières vers lesquelles les larves de poissons peuvent dériver à la fin de leur développement. Il est admis que les régulations mises en oeuvre par les organismes pour faire face à leur environnement au cours des premières étapes de leur vie peuvent avoir des conséquences sur leur trajectoire de vie ultérieure (plasticité développementale). Ainsi, l'objectif principal de cette thèse était d’évaluer si des conditions d'oxygénation (40% et 100% de saturation) combinées à des conditions thermiques (15 et 20 °C) au stade larvaire, pouvaient avoir des impacts durables sur la physiologie des futurs juvéniles de bar (Dicentrarchus labrax). Nos résultats ont révélé que les retards de croissance associés à la plus basse température et à l’hypoxie au stade larvaire induisent une croissance compensatrice. De plus, les analyses des réserves hépatiques en glycogène et en lipides ont révélé que le métabolisme des juvéniles pourrait être affecté par les conditions environnementales au stade larvaire. Par ailleurs, nos données indiquent que la capacité d'extraction de l'oxygène a été affectée chez des juvéniles en raison de déformations operculaires causées par l’exposition précoce à l'hypoxie. Enfin, l'exposition précoce à l'hypoxie induit une sur-expression à long terme de gènes de l'hémoglobine de juvéniles replacés en situation d’hypoxie. Globalement, nos résultats contribuent à faire avancer les connaissances sur la façon dont les poissons marins font face aux changements climatiques actuels<br>In the context of global change, decrease in oxygen availability (hypoxia) combined with rising water temperature are especially prevalent in coastal regions, towards which marine fish larvae may drift at the end of their development. It is well admitted that the physiological regulations implemented by organisms to cope with their environment during the early life stages of life can cause profound consequences in their subsequent life-history trajectory (developmental plasticity). Therefore, the main objective of this thesis was to investigate whether ecologically relevant conditions of oxygenation (40% and 100% air saturation) combined with thermic conditions (15 and 20 °C), occurring at the last stages of larval development of European sea bass (Dicentrarchus labrax) larvae, could have long-lasting impacts on juvenile physiology. Our data showed that growth depression resulting from low temperature and hypoxic conditions at larval stage induced a subsequent compensatory growth. Moreover, our analyses of hepatic glycogen and lipid stores revealed that metabolic features of juvenile could be affected by early exposure to oxygen and temperature conditions. Furthermore, our data revealed that oxygen extraction capacity was affected due to opercular deformities caused by early exposure to hypoxia. Finally, when seabass juveniles, that have been exposed to hypoxia at larval stage, were under chronic hypoxic condition they show a long-term up-regulation of hemoglobin genes. Overall, our findings contribute to make predictions of how the marine fish communities could be altered by current climate change

Full textAbstract:
Change is best carried out by individual teachers, and, thus, identifying and resolving teachers concerns about an innovation is imperative in guiding the change process to a successful point of implementation. The purpose of this study was to identify concerns that teachers experienced when implementing the Information Technology curriculum in all intermediate schools in Kuwait and to examine the relationships among teachers reported stages of concern and other factors, such as gender and experience. The stages of concern, one dimension of the Concerns-Based Adoption Model (CBAM), was applied to reveal teachers concerns. The Stages of Concern Questionnaire (SoCQ) and a demographic survey were completed by 248 respondents. The SoCQ measures seven stages of concern that reflect three dimensions: self (awareness, informational, and personal); task (management); and impact (consequence, collaboration, and refocusing Group profile analysis revealed that teachers had four high concerns related to collaboration, personal, refocusing, and informational stages. Teachers also reported low concerns at the management and awareness stages. Both females and males reported collaboration as their greater concern. Teachers with more years of experience reported higher impact concerns. The analysis of individuals peak concerns revealed that the majority of the respondents were adopters of the innovation. The analysis of the first highest and second highest concerns among teachers revealed the development of three patterns of concerns: self concerns, mixed concerns, and impact concerns. Results indicated that the majority of teachers were at the mixed-concern level. With more years of experience, teachers concerns shifted from self to task and finally to impact concerns. The results of concern analysis are consistent with Fullers theory of concern development. MANOVA revealed significant differences in means between females and males at management and refocusing stages. Females had higher concerns about management; males had higher refocusing concern. However, no significant relationship was found between experience and the reported stages of concern. For successful implementation, the concerns of teachers must be resolved. The CBAM including the SoCQ is recommended to KISITP coordinators as a diagnostic tool to facilitate change and to provide appropriate staff development. Suggestions were made for future research to continue validation of the SoCQ in Arabic cultures.

Full textAbstract:
Ocean acidification is a great concern worldwide. It has important impacts on the shellfish industry. However, more information is needed to assess the impacts of ocean acidification (OA) on economically important shellfish in a realistic industry setting. The goal of this thesis was to determine the effects of OA on the early developmental stages of the Pacific oyster, Crassostrea gigas. To better represent industrial-scale oyster production than is possible in small-volume, short-term laboratory studies, experiments were conducted at the Island Scallops hatchery facility using large volume containers and appropriate time scales. In Chapter 2, I investigated the effects of acidification on fertilization and larval development to explore the potential links between vulnerability at these life stages and documented mass mortality events in hatcheries in the past. Elevated pCO₂ contributed to increased egg fertilization. However, not all fertilized eggs were viable, and elevated pCO₂ reduced the likelihood of further development to later embryonic stages, resulting in decreased overall fertilization success in C. gigas. Increased pCO₂ levels also negatively affected oyster larvae by reducing growth and reducing the production sufficiently large to be suitable for aquaculture rearing practices. Larval deformity and mortality also showed a trend towards increases in acidified conditions whereas feeding was reduced. In Chapter 3, I assessed early development in benthic juveniles to test for potential for carry-over and/or acclimation effects of prior larval exposure to elevated pCO₂. Settlement did not depend on pCO₂ conditions during the larval phase. However, metamorphosis was reduced when larvae had been exposed to elevated pCO₂ levels. Juvenile growth and condition were both reduced after juvenile’s exposure at higher pCO₂ levels, but shell strength was unaffected.

Overall, these findings suggest that OA had negative impacts on multiple life history stages in C. gigas. However, the lack of larval exposure effects on juvenile growth or condition suggests an absence of carry-over effects or acclimation for juveniles. These results have important implications for the aquaculture industry and for the development of best practices for combating the effects of ocean acidification.<br>Science, Faculty of<br>Zoology, Department of<br>Graduate

Full textAbstract:
This study examined how the Compassion Project, a collective theatre and social learning program, fostered positive youth and group development. The Compassion Project involved over 200 secondary students who participated in four theatre-making and social learning phases, where they inquired upon the topic of safe and caring schools. Through the process of collective theatre-making, students co-created two original plays (The Flip Side and Focus) about their social and emotional experiences in school. A/r/tography, the arts education research methodology for this study, emphasizes living inquiry and reflective practice through the examination of the in-between spaces of art-making/researching/teaching (a/r/t). Expanding upon the field of a/r/tography, this study introduces the rendering of the fourth wall as a theatre education research lens. By conceptualizing the theatre classroom as a stage, the rendering of the fourth wall directs attention to several perspectives: to the students, teacher-directors, players, and audience on both the classroom and stage sides; to the spaces in between the imaginary world of the play and the real life experiences of the inquirers; and, to the theatre-making and reflective practices. Based on observations, interviews, circle talks, and students’ written reflections, stories, and scripts, the data are analyzed and presented throughout the dissertation. The findings are conceptualized as the social art effects, which are the benefits that result from students’ social and theatre-making actions and interactions. The conceptualization also combines psychological, pedagogical, and theatre-based theories, such as positive psychology, complexity in education, and collective theatre. As a way to organize the data, the findings on the social art effect are categorized into three components: learning systems, developmental stages, and change mechanisms. This study illustrates how students’ social conditions are critical, and precede learning conditions. Furthermore, this study emphasizes the importance of integrating social learning and complex systems theories into the curriculum as a way to optimize learning spaces and to foster positive youth and group development.

Full textAbstract:
This study focused on female elders living in age-segregated communities. It investigated the direction and strength of the relationship of Openness to Experience and Neuroticism to the resolution of Erik Erikson's Trust and Integrity stages, and to a Total Resolution score. The 62 volunteer subjects, age 67 to 99, lived in eleven retirement and/or assisted care facilities in Richmond, Virginia.;Personality domains were measured by the NEO Personality Inventory (NEO-PI). The Measures of Psychosocial Development (MPD), an instrument based on Erikson's theories, was used to assess resolution.;It was hypothesized that Openness to Experience would show a significant positive correlation with each of the resolution scores. Additional hypotheses stated that there would be a significant inverse relationship between Neuroticism and each resolution measurement.;Data from the study were submitted to product-moment correlations to test the hypotheses. In addition, step-wise multiple regression was used, to determine the extent to which personality and demographic variables explained the resolution variables.;Results indicated no significant relationship between Openness and Resolution of Trust or Resolution of Integrity. There appeared to be a statistically significant positive correlation between Openness and Total Resolution. However, subsequent regression equations revealed that Openness did not add significantly to Neuroticism in explaining the variance in Total Resolution.;Correlation data showed that Neuroticism demonstrated a significant, apparently meaningful inverse relationship to each of the three resolution scores. The Neuroticism hypotheses appeared to be confirmed in this study. Other than Neuroticism, no demographic (age, education, marital status) or personality variable helped explain the variance in the resolution scores.;The study's data and observations, combined with the results of previous research, suggested three areas of application: counseling implications, promulgation of information about elders, and the importance of intergenerational contacts. It was posited that the study results could be generalized to other female elders living in age-segregated communities. A number of suggestions for further study were included.

Full textAbstract:
The brown rot fungi belong to a group of fungal pathogens that causes considerable damage to cultivated fruits trees, particularly stone fruits and apples in the temperate regions of the World and during the postharvest with an important economic impact. In particular in Italy, it is important to monitor the Monilinia population to control economic losses associated to the peach and nectarine market.
This motivates the research steps presented in this dissertation on Monilinia Italian isolates. The Monilinia species collected from stone fruits have been identified using molecular analysis based on specific primers. The relevant role of M. fructicola was confirmed and, for the first time, it was found also on apple fruits.
To avoid the development of resistant strains and implement valid treatment strategies, the understanding of the fruit natural resistance during different developmental stages and the assessment of the Monilinia sensitivity/resistance to fungicides are required.
The relationship between the inhibition spots and the phenolic compounds in peach fruit peel was highlighted in this research.
Three methods were used to assess isolate resistance/sensitivity, the amended medium, the Spiral Gradient Endpoint Method (SGD) and the Alamar Blue method.
The PCR was used to find possible mutation points in the b-tubulin gene that is responsible for fungicide resistance. Interestingly, no mutation points were observed in resistant M. laxa isolates, suggesting that the resistance could be stimulated by environmental factors.
This lead to the study of the effect of the temperature on the resistance and the preliminary results of in vitro tests showed that maximum inhibition was observed at 30°C.
