Role of work-family facilitation in the relationship between environment factors and outcomes in work and non-work domains.

Gopalan, Neena January 1900 (has links)
Doctor of Philosophy / Department of Psychology / Ronald G. Downey / Literature on work and family, the two important domains in an individual’s life, has focused heavily on the conflicts that could occur when individuals try to juggle between their responsibilities in the two domains. Lately, there has been enthusiasm to also study the facilitation aspects that could result from being engaged in both domains. This dissertation empirically tests the Resources-Development-Gain model (RGD), a recently developed work and family facilitation model, which include work and non-work factors that can bring facilitation. Over 500 academic faculty members from four universities completed an online survey comprised of demographic items, family and work variables, variables to measure facilitation, outcome variables in both domains, and personality variables. The hypothesized model (model 1) was analyzed using AMOS, and was found to be a poor fit. Personality factors included as moderators in the facilitation process were found to be non-significant and hence dropped from the modified model (Model 2). This was a significantly better fit. Model 3 was analyzed to see if a better fit would be obtained when personality variables were directly connected to outcome variables. As Model 3 did not add anything significant, Model 2 was accepted. The findings suggest that faculty tenure influenced their turnover intentions, with new academic faculty and full professors showing lower turnover intentions. Family support brought facilitation from one’s family to work and contributed to life satisfaction, while organizational support contributed to facilitation from one’s work to non-work life. No significant overlaps were found between work and family domains in the facilitation stage, but were observed at the outcome levels. Thus, job satisfaction in the work domain contributed to overall life satisfaction in the family domain. Satisfaction in one’s personal relations also tended to influence one’s turnover decisions. Future directions for research and recommendations are discussed.

La planification du littoral aquitain : l'héritage de la MIACA à l'épreuve du temps / Planning the Aquitaine coastline : the heritage of MIACA in the test of time

Casamayor-Mongay, Myriam 07 January 2019 (has links)
La planification territoriale évolue dans sa pratique. En effet, de la gestion de l’usage des sols exclusivement menée par l’Etat central, elle intègre une dimension plus stratégique et partenariale, au fil de l’apparition des collectivités nouvellement compétentes en matière d’urbanisme, au regard des différentes lois de décentralisation de 1983,1985 et 2015. Cinquante ans après la première planification par la Mission Interministérielle pour l’Aménagement de la Côte Aquitaine (MIACA), dont l’objectif a été de développer le tourisme pour le plus grand nombre, et en tenant compte de l’élaboration actuelle d’un document stratégique par la Région Nouvelle-Aquitaine (SRADDET), il a paru intéressant d’investir le sujet des visions pour le littoral de l’ex-Aquitaine. Elles se définissent par les trajectoires de développement préférables d’une sélection de techniciens et d’élus de cet espace. Afin de les définir, la recherche de valeurs pour le littoral aquitain par des membres du GIP Littoral Aquitain a semblé être une piste intéressante. Plus précisément, il est retenu comme définition des valeurs les représentations sociales indiquant les éléments de l’histoire à conserver ou au contraire à rejeter pour l’avenir. La contribution de cette thèse a ainsi pour but de comprendre ce qui importe aux acteurs publics du littoral ex-Aquitaine de transmettre aux générations futures. Elle vise également à s’interroger sur le processus par lequel un objet historique perdure ou non dans la période contemporaine grâce aux notions d’héritage et d’hérédité inspirées de Patrick Geddes. Ce travail teste alors l’hypothèse que les objets de l’Histoire tels que la planification territoriale de la MIACA, puissent servir comme outil d’aide à la décision, dans notre cas, comme le support d’une définition d’une vision pour le littoral aquitain. Pour y parvenir, cette recherche s’appuie particulièrement sur les effets du modèle d’aménagement touristique de la MIACA qui s’étend de 1967 jusqu’à l’organisation actuelle du littoral aquitain en 2017. En outre, les actions menées par les membres du GIP Littoral Aquitain, incarnant une gouvernance devenue plus complexe depuis les lois de décentralisation, enrichissent également le propos. Concrètement, afin de rechercher les valeurs pour le littoral aquitain, d’une part les différentes représentations sociales d’une sélection de techniciens et d’élus membres du GIP Littoral Aquitain sont mises en débat. D’autre part, les gestions de la planification de la MIACA par les élus à l’échelle communale et l’évaluation de leurs effets à l’échelle régionale sont étudiées. Concernant l’échelle communale, cinq sites (Carcans-Maubuisson, Le Porge, Capbreton, Ondres et Hendaye) ont été analysés à partir des discours justifiant de la transmission ou non des objets de la MIACA et de l’évolution des décisions prises dans le cadre des documents d’urbanisme par une comparaison des POS et des PLU. / Territorial planning is changing in practice. It has shifted from a management of land use exclusively conducted by the central government towards a more strategic and partnership-based approach, since the emergence of newly competent authorities in urban planning under the different Decentralization laws of 1983, 1985 and 2015. Fifty years after the first planning territorial by the Interministerial Mission for the Development of the Aquitaine Coast (MIACA), whose objective was to develop tourism for the greatest number, and taking into account the elaboration of a strategic document by the Region of New Aquitaine (SRADDET), it seemed relevant to study the existing visions of the coastline of the former Aquitaine. They are defined as the preferable trajectories of a selected number of technicians and elected representatives of this region. More specifically, these visions stem from different social representations concerning the values of the Aquitaine coastline, which in turn are understood as what stakeholders wish to conserve or to reject for the future. The aim of this thesis is to understand what public stakeholders of coastal ex-Aquitaine seek to transmit to future generations. It also aims to question the process by which a historical object is transmitted to the contemporary period by using the notions of heredity and heritage discussed by Patrick Geddes. It is argued that historical objects such as the MIACA territorial planning can serve as a decision-making tool and, in our case, as the support of a definition of the vision of coastal Aquitaine. Therefore, the research is particularly based on the effects of the MIACA tourism development model between 1967 and the current organization of the Aquitaine coast in 2017. In addition, a study of the action undertaken by members of the GIP Littoral Aquitain, reflecting a the movement towards a more complex governance since the decentralization laws, also enriches the subject. More specifically, the values of the Aquitaine coast will be analyzed by discussing the different social representations of a selected number of technicians and elected members of GIP Littoral Aquitain. The management of MIACA's planning and practices by elected representatives at the municipal level as well as the evaluation of their effects at regional level will give relevant insights. Concerning the municipal scale, five sites (Carcans-Maubuisson, Le Porge, Capbreton, Ondres and Hendaye) have been analyzed basing on the discourses justifying or not the transmission of the objects of the MIACA and the evolution of the decisions taken in the planning documents.

Environmental impact assessment and process simulation of the tidal current energy resource in the Strait of Messina

El-Geziry, Tarek Mohamed Ahmed January 2010 (has links)
Interest in exploring renewable energy resources has increased globally, especially with recent worldwide intentions to maintain the global climate. Looking at the oceans as a vast sustainable clean energy resource to satisfy present high humankind energy demands has been strongly recommended. Several types of renewable energy resources exist in the oceans: waves, tides, thermal and salinity variations, currents, and offshore winds. Exploiting tidal currents is considered one of the most effective approaches to the generation of electricity. Tidal turbines are deployed beneath the sea surface to transfer the kinetic energy in tidal currents to mechanical energy suitable for ongoing conversion to electricity and subsequent transmission. However, choosing a suitable site to deploy these turbines is not a trivial process. Various constraints must be satisfied subject to basic criteria dependent upon local factors, technology limitation and economic consideration. In addition, an important issue to consider is taking care to harness energy from tidal currents with minimum possible impact on the surrounding environment. The present study justifies the nomination of the Strait of Messina as an exceptional tidal current energy resource within the Mediterranean Sea basin. The maximum tidal current velocity at spring peak tide through the Strait may exceed 3 m/s. This mainly results from the tidal phase-difference (180°) between the northern (Tyrrhenian Sea) and southern (Ionian Sea) tips of the Strait, associated with a difference of 0.27 m in tidal wave amplitudes. In addition, the complex coastline configuration of the Strait plays an important role in enhancing tidal current velocities. Therefore, the Strait of Messina fulfils the basic criterion (2 m/s tidal current velocity) to be considered as a valid tidal current energy resource. This massive tidal current energy resource is assessed in the present study. A detailed full desk-based Environmental Impact Assessment (EIA) study is performed using the interactive matrix approach in order to investigate the anticipated environmental impacts on the marine ecosystem of the Strait of Messina resulting from the harnessing of energy from its tidal currents. Through the EIA study the different environmental components, both biotic and abiotic, which may be affected by the energy extraction process, are explained. In addition, the proposed key project activities are listed; the likelihood of occurrence and the magnitude of impact interaction with the environmental components are evaluated. The final judgment matrix guides to make a right decision on the proposed project. From the resulted matrix, the major impacts do not exceed 10% of the total anticipated effects. The positive point is that all the expected impacts, including the majors, can be controlled and minimised to the lowest possible limits by applying a good monitoring programme. The University of Edinburgh “Tidal Flow Development (TFD)” numerical model is used to mimic the tidal environment of the Strait of Messina in different cases. The model successfully simulates the tidal flow regime within the Strait under some exceptional conditions. Modifications to the main numerical code and coefficients were necessary in the present research to adjust the model according to each case study. In the three different cases of simulation, using these exceptional coefficients, the model simulates the main tidal characteristics of the tidal flow within the Strait. According to the results of the numerical simulation process, tidal currents are more intensive close to the eastern coast of the Strait of Messina near to Punta Pezzo. This area is far from any ferry route between Italy and Sicily. The best location to deploy tidal turbines for the energy extraction process is therefore recommended to be within these surroundings. Finally, a physical (laboratory) model is used to simulate the flow regime within the Strait of Messina. The Particle Image Velocimetry (PIV) technique was applied in the flow-table tank at the University of Edinburgh. The physical model simulates the flow behaviour within the Strait of Messina to a satisfactory degree. The cyclonic and anti-cyclonic motions observed at the southern extremity of the Strait are also very well simulated. The results of the present study assure confidence in the use of tidal currents within the Strait of Messina as a renewable energy resource. The safety of the environment must be ensured by following environmental guidelines, respecting the energy extraction limits and by applying an effective monitoring programme. The later is strongly recommended to be an adaptive one in which higher environmental authorities are able to watch, revise and control the environmental team within the project. These authorities are also able to postpone the project in case of any severe environmental case. The simulation processes emphasize the effect of morphometry and topography in enhancing tidal currents in the Strait of Messina. Moreover, numerical simulation assures that the complex morphometry and bathymetry, in addition to the open boundaries of the Strait of Messina, are challenging issues for modellers in order to mimic the real tidal current resource in the case of the Strait of Messina. The study also strongly recommends applying a more effective numerical model than TFD to assess the tidal hydrodynamical environment before and after any proposed energy extraction process. This will certainly, with the EIA of the marine ecosystem, help to make a right decision about the proposed project in order to achieve the goal of using clean and clear renewable energy resources while maintaining both natural and hydrodynamical environments to the most possible safest degree.

The Effect Of

Akincilar, Vildan 01 June 2010 (has links) (PDF)
This study aims to investigate the effects of the &ldquo / PLEASE&rdquo / (a general paragraph writing strategy ) writing strategy instruction through the Self-Regulated Strategy Development (SRSD) model on descriptive writing of fifth grade English language learners studying in a private primary school in Istanbul. The current study specifically focuses on if instruction on pre-writing planning through the SRSD model results in improvements in students&rsquo / written products, planning behaviors and self-beliefs as writers. For the study, eight fifth grade students participated in a writing club activity offered by the researcher at school. They were taught strategies for planning and drafting descriptive paragraphs, and the procedures for regulating the use of these strategies and the writing process itself. The data collection tools included comparison of students&rsquo / final pieces of writing in terms of overall quality and length, retrospective verbal protocols, individual interviews, and questionnaires all of which were conducted both at the pre-intervention and the post-intervention phases. As a result, the pre-test and the post-test writing scores indicated that each student experienced improvement in terms of overall quality and length of the written products. The strategy training helped students become more aware of the need for pre-writing planning and they started to engage in planning prior to writing in real practice. After the treatment, the students also experienced increased self-confidence.

Den sociala utvecklingsmodellen : En kvalitativ studie om mötesplatsers arbete för att stärka barn och ungas prosociala utveckling

Hallberg, Linda, Westby, Lovisa January 2023 (has links)
Det brottsförebyggande arbetet har stött på stora utmaningar i att förebygga att barn och unga rekryteras till kriminella gäng. Genom att arbeta förebyggande i tidiga åldrar och stärka barns prosociala utveckling minskar risken att unga individer utvecklar antisocialt beteende. I en mindre kommun i Sverige arbetar personal på mötesplatser, tidigare benämnt ungdomsgård, med att stärka barn och ungas prosociala utveckling. Detta arbete utformas utifrån den sociala utvecklingsmodellen [SDM]. Syftet med studien är att undersöka hur personal på mötesplatser upplever sitt arbete med att stärka barn och ungas prosociala utveckling, och hur detta kan minska nyrekrytering till kriminella gäng. Analysen baseras på fyra intervjuer. Resultaten visar att det går att arbeta med modellen för att stärka barn och ungas prosociala utveckling. Respondenterna lyfter att barn och unga behöver känna att de hör hemma någonstans och ser att mötesplatserna kan utgöra ett positivt sammanhang för dem att utvecklas i. SDM strukturerar arbetet och ger möjligheter till att minska unga individers sårbarhet för gängrekrytering, men det förebyggande arbetet måste börjas tidigt. / It is challenging to prevent youths' from getting recruited to criminal gangs. Strengthening youths' prosocial development will in parallel reduce the risk of developing antisocial behavior. In a small municipality in Sweden, youth centers are working to strengthen youths' prosocial development. Their work is based on The Social Development Model [SDM]. The purpose of the present study was to investigate how staff at these youth centers work to strengthen prosocial development in youth, and how this can reduce recruitment to criminal gangs. Four interviews with staff from the youth centers were carried out. Results showed that by employing the SDM enhances youths’ prosocial development. Youths explicitly have a need to feel that they belong somewhere. Respondents also expressed that their work with SDM at the youth centers creates a positive context where youth can develop. SDM provides structure and reduces vulnerability in youth which in turn hinders gang recruitment. Nonetheless, in order for the prevention to be successful, it has to start early.

Development and Functional Characterization of Fetal Lung Organoids

Laube, Mandy, Pietsch, Soeren, Pannicke, Thomas, Thome, Ulrich H., Fabian, Claire 24 March 2023 (has links)
Preterminfants frequently suffer frompulmonary complications due to a physiological and structural lung immaturity resulting in significant morbidity and mortality. Novel in vitro and in vivo models are required to study the underlying mechanisms of late lung maturation and to facilitate the development of new therapeutic strategies. Organoids recapitulate essential aspects of structural organization and possibly organ function, and can be used to model developmental and disease processes. We aimed at generating fetal lung organoids (LOs) and to functionally characterize this in vitro model in comparison to primary lung epithelial cells and lung explants ex vivo. LOs were generated with alveolar and endothelial cells from fetal rat lung tissue, using a Matrigel-gradient and air-liquid-interface culture conditions. Immunocytochemical analysis showed that the LOs consisted of polarized epithelial cell adhesion molecule (EpCAM)-positive cells with the apical membrane compartment facing the organoid lumen. Expression of the alveolar type 2 cell marker, RT2-70, and the Club cell marker, CC-10, were observed. Na+ transporter and surfactant protein mRNA expression were detected in the LOs. First time patch clamp analyses demonstrated the presence of several ion channels with specific electrophysiological properties, comparable to vital lung slices. Furthermore, the responsiveness of LOs to glucocorticoids was demonstrated. Finally, maturation of LOs induced by mesenchymal stem cells confirmed the convenience of the model to test and establish novel therapeutic strategies. The results showed that fetal LOs replicate key biological lung functions essential for lung maturation and therefore constitute a suitable in vitro model system to study lung development and related diseases.
