L'émergence des amplificateurs à fibre et l'inévitable accroissement du débit ont drastiquement augmenté la complexité des systèmes de transmission optiques, imposant une évolution des composants photoniques. Des techniques de caractérisation fiables et précises sont alors indispensables pour mener une analyse appropriée des caractéristiques et des performances desdits composants. La réflectométrie à faible cohérence sensible à la phase est une technique bien adaptée à la détection, localisation et quantification des discontinuités d'indice dans les composants optiques et photoniques. Dans le cadre de cette thèse, elle a été appliquée à l'analyse de différents composants photoniques innovants, tels que les réseaux de Bragg à fibre, les fibres optiques spéciales et les lasers à semi-conducteurs soumis à une injection optique. Les résultats obtenus situent cette technique comme un véritable outil d'investigation qui s'avère très performant pour l'assistance et l'aide à la conception des nouvelles générations de composants photoniques.

<p>The “good girl” is today an accepted and widespread notion. It is delimited to young girls and women who are characterised to be, for example, ambitious, high performing, working too much and risks developing mental illnesses. In today’s society women are assumed to pursue their career alongside maintaining the main responsibility for the household and family. The overarching purpose of this study has been – via a hermeneutic approach and based on the theory of symbolic interactionism – to elucidate and contribute knowledge to the social role of being a “good girl” and the associated implications for a woman’s identity and career. The aim has moreover been to address the differences between the two groups of respondents: women born in the 1980s and women born in the 1960s.The study is based on six individual semi structured interviews and two group interviews. The purpose is to gain a deeper understanding of and, thereby, a better interpretation of the phenomena of “good girls”. The interviews were conducted on a sample suited to the purpose, where the younger group of respondents will have studied at least three years at the university before graduating. The older groups of respondents have studied at least four years at an academic level before taking up employment. The results show that all respondents are characterised by ambitious identities, which create conflicts between, on the one hand, how they perceive themselves and, on the one hand, how others expect them to act.</p>

<p>The purpose of this project is to study the women involved in the SOS Children’s Villages; the influence of the association on their views on life, as seen from a human-rights and a religious perspective. Questions such as why they chose to work with the association and what it gives them to do so are treated in this study.</p><p>My goal has been to study and present different aspects of something so important, but yet so unfamiliar. The method used in this project is minor field studies, which means visiting the villages, living with the families and observing their daily lives. The means of acquiring the information necessary for this study is by qualitative interviews with the mothers.</p><p>A theoretical framework has been used as a complement to the study, and it is also used to bring greater understanding to the SOS mothers and how they have shaped their lives.</p><p>My ambition with this essay is to bring out their individual experiences on how they view their own lives at present and what meaning life has given them. I have used seven of the 14 interviews conducted.</p><p>The outcome shows that several factors play important roles as to why the mothers decided to work with the association. Such factors were socioeconomic and sociopsyhologic factors. Other conclusions that were drawn after this field trip were that the women are very vulnerable to the social situation in Lebanon. They need someone to support them since the men are the primary providers. If the women do not find someone to marry they need to find another source for provision and the SOS children’s Association is one way to go. The sense of Coherence that these women had was indeed strong, they felt meaningfulness in what they did, they had comprehended the situations at hand and could manage the situations as predictable, and they have the confidence to know that everything will work out in the best way possible.</p> / Uppsatsen har givits ut som bok 2009 med titeln: "Lebanese SOS Children's Villages: Stories of the village mothers" av VDM Verlag, Saarbrücken.

<p>Syftet med denna studie är att knyta an till Högskolan i Gävles riktlinjer för ett examensarbete, undersöka betydelsen av visualisering på en arbetsplats samt kartlägga en pedagogs uppfattningar av dennes tankar med hjälp av datorprogrammet Complador. Någon tidigare forskning har inte funnits inom detta område, vilket gjorde att ett intresse väcktes hos författarna. Studien bygger på litteraturstudier samt intervjuer. För att få svar på visualiseringens betydelse valdes intervjuer med en rektor samt tre pedagoger, kartläggning av en pedagogs uppfattningar gjordes via Complador vilket ledde till resultatet i denna studie. Intervjuerna visar på att visualisering har en stor betydelse både för pedagogerna själva samt deras dagliga arbete, både som kollega och klasslärare. Kartläggningen fick pedagogen att se och reflektera över dennes uppfattningar vilket gjorde att denne ställde sig positiv till Complador.</p>

<p>In this study 165 Swedish parents of young children with Downs’s syndrome (DS) were investigated regarding their perception of the quality of the first information and support received after the birth of the child. The parents’ opinions were compared with clinical routines at the paediatric clinics regarding these issues. Strong clinical ambitions fell short, however, since 70 % of the parents felt insufficiently informed; 56 % felt unsupported, and the timing of the disclosure varied between 0 hour to >5 days. On the basis of a grounded theory analysis the parents’ written narratives regarding the quality of the first information and support were analysed to better understand the reasons underlying the parental dissatisfaction. Criticisms were raised by the parents concerning: the low communication skills by professionals; the lack of privacy; too much negative information; and an unmet desire to early meet other DS parents. </p><p>The implications of being DS parents regarding their daily life were examined by measuring parental health, stress, sense of coherence, employment and sick leave rates. Results were compared with those in a randomly selected group of parents of healthy age-matched children. The similarities between the DS and control parents were more pronounced than the differences regarding divorce rates, siblings in the family, time spent on child care, employment and sick leave rates, and their self-perceived health, stress, and sense of coherence. However, self-perceived health of the DS mothers was impaired and stress was increased. A small group of DS parents (5 mothers and 1 father) had an extremely high rate of sick leave and no such group was seen in the control parents. In addition, the DS mothers stayed at home because of the child’s sickness most frequently and the DS fathers stayed at home for this reason more than control mothers.</p><p>Conclusions: Existing guidelines for optimal first information and support of new parents of children with DS are not always followed in Sweden. Qualitative clinical improvements from the parents’ perspective are proposed. Most DS parents live an ordinary family life in respect to the measured parameters, but the risk for health deterioration, particularly in DS mothers, might need attention.</p>

<p>This dissertation has two parts. Firstly, satisfaction with life as a whole and with 10 life domains (using an instrument termed LiSat-11 with 6-graded scales) is described in a nationally representative sample aged 18-64 years (n: 2,533) and is related to some socio-demographic circumstances. Secondly, vocationally disabled people (n: 109) at an employability institute are prospectively followed in order to determine their life satisfaction and to identify early predictors of vocational rehabilitation outcome.</p><p><u>Main results</u>: Gender independently, 70 % of the national sample were satisfied with life as a whole (were happy). The ten domains formed a 4-factor pattern: ”Closeness, Health, Spare time, Provision”. Seven domains were sizeable predictors of overall life satisfaction. In a complex manner socio-demographics were predictive of (gross levels) all LiSat-11 items. Main predictors were perceived health, immigrant status and educational level. </p><p>Generally, the vocational rehabilitees had low LiSat-11 levels except for the closeness items. They had relatively poor background resources (low “sense of coherence“ level) for successful coping. Whereas a positive rehabilitation outcome was accompanied by increases in several LiSat-11 aspects, only satisfaction with the vocational situation was clearly responsive. Three early predictors of outcome were identified: belief in vocational return, educational level and sense of coherence. </p><p><u>In summary</u>: Besides providing reference values for the LiSat-11 instrument, this dissertation demonstrates that different socio-demographic factors influence different areas of concern (domains) in 18- to 64-year-old Swedes. In turn, satisfaction derived from different areas heavily influences level of overall life satisfaction. Moreover, the vocational rehabilitees generally seemed to be predisposed to being poor copers, possibly a major background of low levels of many LiSat-11 aspects. The identified set of predictors of the outcome of vocational rehabilitation emphasizes a need for focusing on psycho-social aspects within vocational rehabilitation.</p>

<p>The high prevalence of diabetes mellitus among the Sudanese population is linked to obesity, poor glycaemic control and a high rate of complications. This study investigated 1/ Leptin hormone and its correlations with different biochemical characteristics in Sudanese diabetic subjects, 2/ The impact of glycaemic control on pregnancy outcome in pregnancies with diabetes, 3/ The glycaemic response to Sudanese traditional carbohydrate foods, 4/ The influence of glucose self-monitoring on the glycaemic control among this population, 5/ The health related quality of life in Sudanese subjects with diabetes-related lower limb amputation. </p><p>Leptin was significantly lower in diabetic subjects compared with controls of same BMI in both females (P =0.0001) and males (P =0.019). In diabetic subjects, serum leptin correlated positively with the homeostatic assessment (HOMA) of both beta-cell function (P =0.018) and insulin resistance (P =.038). In controls, leptin correlated only with insulin resistance. Pregnancy complications were higher among diabetic compared with control women (P<0.0001) and varied with the type of diabetes. Infants of diabetic mothers had a higher incidence of neonatal complications than those of non-diabetic women (P<0.0001). In six Sudanese traditional carbohydrate meals over all differences in incremental AUCs were significant for both plasma glucose (P = 0.0092) and insulin (P = 0.0001). Millet porridge and wheat pancakes displayed significantly lower post-prandial glucose and insulin responses, whereas maize porridge induced a higher post-prandial glucose and insulin response. In type 2 diabetic subjects SMBG or SMUG was not related to glycaemic control. In type 1 diabetic subjects, SMBG was significantly associated with better glycaemic control, as assessed by HbA1c (P=0.02) and blood glucose at clinic visits (P=<0.0001), similar associations were found for SMUG respectively. Neither glycaemic control nor glucose self-monitoring was associated with education level. Diabetic subjects with LLA had significantly poorer HRQL compared to a reference diabetic group (P=<0.0001). Duration of diabetes and amputation had negative impact on HRQL in subjects with LLA (P=<0.0001) respectively. Diabetic subjects with LLA had decreased sense of coherence and high presence of symptoms. Improving health services at the primary level is important to reduce the complications and burden of disease in the Sudanese population.</p>
