In Sweden 13% of the general adult population (16-84 years), with or without hearing aids (HAs), report that they have difficulties following a conversation when more than two people are involved. This means that more than one million people in Sweden (9 500 000 inhabitants in total) report subjective hearing difficulties. Observations further indicate that that people with hearing impairment (HI) have an unfavorable position in the labor market. Individuals with HI report poorer health more frequently and estimate their own health to be worse than their normally-hearing peers. Increased unemployment, early health-related retirement and sick leaves are also more common for people with hearing loss compared to the population at large. The focus of the present thesis is employees with mild-moderate aided HI in the labor market. The research project had three general aims: 1) to develop knowledge about how HI interacts with cognitive abilities, and different types of work-related sound environments and workrelated tasks, 2) develop tests and assessment methods that allow for the analysis and assessment of perceived problems in clinical settings and 3) to develop knowledge that enables the possibility to provide recommendations of room acoustics and work-related tasks for employees with HI. Four studies were carried out. The studies presented in papers I-III are quantitative laboratory studies focusing on health related quality of life, cognition and effort and disturbance perceived in different types of occupational noise (daycare, office and traffic). Paper IV is a qualitative interview study aiming at exploring the conceptions of working life among employees with mild-moderate aided HI. The results from papers I-IV clearly demonstrate that noise has negative effects on employees with mild-moderate aided HI. In addition to generating significantly greater effort and disturbance, it is further reported from the participants that noise at work in combination with a HI has an impact on daily life. This includes a sense of exposure during work hours, physical and mental fatigue after work, and withdrawal from social situations in the work environment and leisure activities. None of the participants with HI performed significantly worse on the visual working tasks employed in this project compared to their normallyhearing peers. This thesis shows that employees with HI objectively perform the employed  working tasks at a level similar to a well-matched normally-hearing control group. Instead, the findings of this thesis indicates that working in a noisy environment with a HI occurs at the expense of this group reporting significantly worse results on subjective measurements, including greater effort and disturbance, and lower physical health status. Interviews with these participants further confirm that these effects are indeed mostly due to noise at the workplace which could have a negative impact both physically, mentally and socially during and after work hours. The main findings of this thesis demonstrate that there is a need for extensive services for employees with HI even after a HA fitting. This thesis therefore emphasizes the importance of identifying the need for assistive listening devices, examining the room acoustics of the individual’s work setting and providing the workplace with information about the consequences of having a HI in order to facilitate communication at work. The latter is especially important as colleagues showing support and employers making adjustments at the workplace (technically or acoustically) are facilitating factors that would benefit both employees with HI and those with normal hearing. Additional research should focus on including and comparing other types of cognitive tests, work-related noises and working tasks. More research is also needed to unravel the complex area of research between factors such as cognitive processes, hearing and effort. / Tidigare forskning har visat att yrkesverksamma hörselskadade oftast har en mindre gynnsam position på arbetsmarknaden. Statistik visar att gruppen upplever en högre grad av trötthet och en lägre grad av arbetstillfredställelse. Avhandlingen har tre övergripande syften: 1) att utveckla ny teoretisk kunskap om hur hörselnedsättning samspelar med kognitiva förmågor, arbetsrelaterad ljudmiljö och typ av arbetsuppgifter, och 2) utveckla test- och utredningsmetoder ger möjlighet till analys och diagnos av upplevda problem samt 3) utveckla kunskap som ger möjlighet till åtgärd och anpassning av ljudmiljöer och arbetsuppgifter på arbetsplatser för hörselskadade. Projektets resultat visar på att yrkesverksamma med hörselnedsättning rapporterar en lägre fysisk hälsostatus och att en högre grad av upplevd ansträngning samt störning kan upplevas när de utför olika arbetsuppgifter i buller. Detta beror bland annat på att de kognitiva förmågorna blir mer belastade i en bullrig miljö och att hörselskadade är mer känsliga för höga bullernivåer. Djupintervjuer med gruppen visar även på att fysisk trötthet upplevs även efter jobbet som i sin tur kan leda till psykosociala konsekvenser för individen. Denna avhandling visar att de negativa effekterna av buller redan ses vid en lätt-måttlig hörselnedsättning hos en grupp som redan använder hörapparater. Från ett kliniskt perspektiv innebär det att dagens rehabiliteringsåtgärder bör vara mer omfattande än endast hörapparaturprovning för denna grupp. Tekniska hjälpmedel (FM-system, streamers, hörslinga, etc.) är viktiga för yrkesverksamma med hörselskada och information om konsekvenserna av att leva med en hörselnedsättning bör nås ut till arbetsgivare och kollegor för att underlätta kommunikation på jobbet.

Thesis advisor: Mary E. Walsh / Poverty has many deleterious effects on child development, including negative impacts on social-emotional health, a developmental domain schools refer to as non-cognitive skills (Dearing, 2008). Unfortunately, children growing up poor often have underdeveloped non-cognitive skills, which significantly predict academic success and well-being (Farrington et al., 2012). Integrated Student Support (ISS) is one emerging approach that holistically supports cognitive and non-cognitive student development (Moore & Emig, 2014). While ISS has been found to improve academic outcomes, limited research examines its impact on social-emotional outcomes. This study focused on one ISS intervention, City Connects, which provides tailored student support plans to every child in a school via school and community-based services (Walsh et al., 2014). The study had three aims. The first was to examine the percentage of City Connects students with and without a social-emotional-behavioral (SEB) Need across levels of risk and service characteristics (i.e., domains, intensity levels, types) in second grade (N=896). The second was to examine improvement in three teacher-rated non-cognitive student outcomes (Prosocial Behavior, Self-Regulated Learning, Academic Effort) from second-fifth grade for City Connects students with and without a SEB Need (N=896). The third was to compare improvement in the same three non-cognitive student outcomes from second-fifth grade for students with a SEB Need in City Connects schools and comparable schools without the intervention (N=1,778). Multilevel modeling assessed aims 2 and 3. Significantly more students with a SEB Need were deemed higher risk and received more health, early intervention, and SEB/counseling services compared to students without a SEB Need in City Connects schools. Further, significant improvements from second-fifth grade were found in Self-Regulated Learning and Academic Effort for City Connects students with a SEB Need compared to those without a SEB Need. Significant improvements were also found over time in Academic Effort for students with a SEB Need in City Connects schools compared to those in comparison schools. Findings support that ISS improves non-cognitive functioning for students attending high-poverty schools. / Thesis (PhD) — Boston College, 2020. / Submitted to: Boston College.

Utilizing ECLS-K:2011 data, this study compares adopted and biological children to account for the role of heritable characteristics in explaining the relationship between family environments and children's cognitive skills. I find that cognitive skills do not differ across adopted and biological children after adjusting for the systematic differences between them. I also find that the relationship between family environment and children's cognitive skills does not differ across adopted and biological children. Taken together, these results suggest that the relationship between family environment and children's cognitive skills is not spurious.

Yes / Objective: We conducted a U.K.-wide survey to collect information on people's beliefs, fears, perceptions, and attitudes to cognitive aging. Methods: This community-based aging survey included 3,146 adults aged 40 years and over. Results: Respondents believed memory might be the earliest cognitive skill to decline (mean: 59.4 years), followed by speed of thinking (mean: 64.9). Those in their 40s were more pessimistic, because they estimated cognitive changes would start up to 15 years earlier than respondents aged over 70. Having a purpose in life, healthy eating, challenging the mind, sleep, and physical activity ranked higher in terms of perceived importance for maintaining or improving cognitive skills. However, less than 50% engaged in any of these activities. Although 91% believed there are things people can do to maintain or improve their cognitive skills, more than 40% were unsure or did not know how to do so. Respondents who strongly agreed that changes in cognitive skills might be a sign of something more serious were significantly more likely to do various activities to benefit their cognitive skills. Conclusion: Results suggest that people are less aware of the potential cognitive benefits of certain activities, such as exercise and diet. It is important to build awareness about the benefits of lifestyles and activities for cognitive health. / Velux Stiftung (Project No. 1034).

Ces dernières décennies, la famille a connu des changements majeurs dans la majorité des pays de l’OCDE. D’une part, le taux de fertilité a baissé ; d’autre part, le nombre de séparation a fortement augmenté. Cette thèse se propose d’étudier les effets de ces changements de la structure familiale sur le capital humain des individus, en l’envisageant comme une nouvelle source d’inégalités. Dans un cadre micro-économique, cette thèse mobilise les outils économétriques pour les appliquer à de larges bases de données. Les trois chapitres de cette thèse présentent des résultats nouveaux sur l’effet de la séparation parentale et de la taille de la famille sur le capital humain de l’individu. Le premier chapitre porte sur l’effet de la séparation parentale en France sur la réussite professionnelle des individus, et montre un effet négatif de la séparation parentale sur le niveau d’étude et la position sociale de l’individu. En s’appuyant sur des données américaines, le second chapitre s’intéresse aux mécanismes expliquant cet effet, et en particulier, sur les changements du temps passé avec les parents. Ainsi, 30% de l’effet de la séparation parentale sur le développement socio-émotionnel des enfants serait expliqué par la baisse du temps passé avec au moins un parent présent. Le troisième chapitre considère un autre aspect de la structure familiale : la taille de la famille. Nous trouvons que l’arrivée d’un troisième enfant dans la famille diminue les compétences socio-émotionnelles des autres enfants, en particulier chez les filles. / Family has known great transformations in the last decades in a large number of OECD countries. On one hand, fertility rates have decreased. On the other hand, the number of separations has increased sharply. This thesis asks whether these major changes of family structure affect child’s human capital, being a new source of inequalities. Using very large datasets and micro-econometric methods, the three chapters present original empirical evidence on whether parental separation and family size impact individual’s human capital. The first chapter studies the effect of parental separation in France on individual’s achievement, and find a negative effect of parental separation on individual’s educational attainment and social position. Using an American dataset, the second chapter asks whether this effect is driven by changes in time spent with parents, and find that 30% of the effect of parental separation on socio-emotional skills is explained by the decrease in time spent with at least one parent present. The third chapter accounts for another aspect of family structure: the number of children. Using a British dataset, we find that having a second sibling in the United Kingdom decreases the child’s socio-emotional skills, especially for girls.

Behavioral and cognitive skills training for increasing assertive behavior in college students were compared to an equally credible expectancy-control. One significant multivariate function successfully discriminated between the behavioral and control groups, and between the cognitive and control groups. This function was interpreted as showing enhanced behavioral/cognitive construction competencies in the behavioral and cognitive groups. A second function, though not significant, suggested that the cognitive training resulted in more aggressive behavior.
