La PrEP pourrait avoir un impact sur la perception du risque du VIH et ainsi influencer les comportements sexuels d’hommes gais, bisexuels et autres hommes ayant des relations sexuelles avec d’autres hommes (gbHARSAH). Les buts de l’étude étaient 1) de comparer les caractéristiques sociodémographiques, les habitudes de vie, les comportements sexuels et relationnels, les antécédents d’infections transmissibles sexuellement et des facteurs psychosociaux liés à la prise de risque d’hommes gbHARSAH en fonction de la perception du risque du VIH et 2) d’examiner l’association entre cette perception du risque et les relations anales sans condom (RASC) selon l'utilisation de la PrEP. Cette étude descriptive corrélative consistait en une analyse secondaire de l’étude ENGAGE réalisée auprès de 945 hommes gbHARSAH. Comparativement au groupe qui se percevait moins à risque du VIH (n = 773), celui qui se percevait plus à risque (n = 172) différait quant aux comportements sexuels. Dans l’analyse non stratifiée, le risque perçu élevé du VIH était associé aux RASC (RC = 2,87; 95 % IC = 1,84 - 4,47) et l’utilisation de la PrEP était associée aux RASC (RC = 12,75; 95 % IC = 3,43 - 47,41). Dans l’analyse stratifiée, parmi les hommes qui n’étaient pas sous PrEP, seule l’association entre le risque perçu élevé du VIH et des RASC était maintenue (RC = 2,91; 95 % IC = 1,86 - 4,57). Cette étude montre l’influence de la perception du risque sur les comportements sexuels, suggérant ainsi la pertinence d’une approche globale de la prévention du VIH. / PrEP may impact self-perceived risk for HIV infection and influence the sexual behaviors among gay, bisexual and other men who have sex with men (gbMSM). The aims of this study were 1) to compare the sociodemographic characteristics and lifestyles, sexual and relational behaviors, history of sexually transmitted and blood-borne infections, and psychosocial factors related to risk-taking behaviors of gbMSM according to self-perceived risk for HIV infection, and 2) to examine the association between self-perceived risk for HIV infection and condomless anal intercourse (CAI) according to PrEP use. This descriptive and correlational study was a secondary analysis of data collected by the ENGAGE study which involved 945 gbMSM. Compared with gbMSM with lower self-perceived risk for HIV (n = 773), those with higher self-perceived risk (n = 172) differed in terms of sexual behaviors. An unstratified analysis showed high self-perceived risk for HIV infection to be associated with CAI (aOR: 2.87, 95% CI: 1.84–4.47) and PrEP use to be associated with CAI (aOR: 12.75, 95% CI: 3.43–47.41). A stratified analysis by PrEP use showed that, among gbMSM who did not use PrEP, only the association between high self-perceived risk for HIV infection and CAI was maintained (aOR: 2.91, 95% CI: 1.86–4.57). This study reveals the influence of risk perception on sexual behaviors and highlights the importance of a global approach to prevention of HIV infection.

Hot och våld på arbetsplatser har länge diskuterats och studerats. Det finns vissa yrkesgrupper som är mer drabbade än andra och läraryrket beskrivs utgöra en av dessa riskgrupper. Under de senaste åren har det rapporterats om en förändring i svenska skolmiljöer där allt fler lärare utsätts för hot och våld. Forskningen om skolvåld har traditionellt fokuserats på elevernas utsatthet vilket utgjort en kunskapslucka kring lärares exponering för hot och våld. Tillgänglig forskning indikerar att utsattheten skiljer sig åt bland lärare, därmed finns ett erkänt behov av att bredda kunskapsbasen inom forskningsområdet.  Syftet med studien var att undersöka hur förekomsten av hot och våld bland lärare ser ut i Värmland. Vidare syftade studien till att belysa vilka faktorer som bidrar till lärares utsatthet samt hur skolorna hanterar hot och våld. För att besvara studiens syfte har ett kvalitativt tillvägagångssätt tillämpats. Datainsamlingen bestod av intervjuer med fem skyddsombud från olika skolor från tre kommuner i Värmland.  I studien framkom en samstämmig uppfattning om att lärare är en utsatt grupp när det kommer till hot och våld. Utsattheten skiljer sig åt mellan olika skolor och årskurser och faktorer som erfarenhet och kön har en viss påverkan på lärares utsatthet. Hur risken att drabbas av hot och våld värderas kan påverkas av attityder och acceptansnivå. Vidare belyser studien en medvetenhet om hot och våld bland lärare. / Threats and violence in workplaces have long been discussed and studied. There are certain professional groups that are more affected than others, and the teaching profession is described as one of these risk groups. In recent years, there have been reports of a change in Swedish school environments where more and more teachers are exposed to threats and violence. Research on school violence has traditionally focused on students' vulnerability, which has created a knowledge gap regarding teachers' exposure to threats and violence. Available research indicates that vulnerability differs among teachers. Thus, there is a recognized need for further research.  The objective of the study was to investigate how threats and violence occurring in school settings among teachers are perceived in Värmland. Furthermore, the study aimed to highlight which factors contribute to teachers' vulnerability and how schools deal with threats and violence. In order to answer the objective of the study, a qualitative approach was applied. The data collection was carried out using interviews with five protection officers from different schools in three municipalities in Värmland.  The study revealed a consensus that teachers are a vulnerable group when it comes to threats and violence. Vulnerability differs between different schools and grades, and factors such as experience and gender have a certain influence on teachers' vulnerability. How the risk of being affected by threats and violence is valued can be influenced by attitudes and level of acceptance. Furthermore, the study highlights an awareness of threats and violence among teachers.

Text in English / Cervical cancer accounts for 34.6% of all the female cancers in Zimbabwe. The purpose of this study was to explore the knowledge, attitudes and perceptions of female student nurses regarding cervical cancer in Zimbabwe using the Health Belief Model (HBM) as a theoretical framework. The ultimate aim was to analyse female student nurses’ risk perception of contracting cervical cancer. A quantitative, cross-sectional descriptive research design was used, using a structured questionnaire for data collection. One hundred and thirty-two (132) respondents were conveniently selected. Descriptive and inferential statistics were calculated using Statistical Package for Social Sciences (SPSS) version 21 software program. The study revealed that 57.9% of the respondents perceive that they are at risk of developing cervical cancer. They believe that screening for cervical cancer is not embarrassing. Knowledge improved with increase in the level of study, there was lack of knowledge of HPV and cervical cancer link. More emphasis on cervical cancer should be put on curricula taught in undergraduate education earlier on in the programme. / Health Studies / M.A. (Nursing Science)

La maladie de Lyme est la maladie vectorielle la plus fréquente dans les pays tempérés et est en émergence dans plusieurs régions du monde. Plusieurs stratégies de prévention existent et comprennent des interventions qui visent les individus, comme le port de vêtements protecteurs, et d’autres qui sont implantées au niveau collectif, dont des interventions de contrôle des tiques dans l’environnement. L’efficacité de ces stratégies peut être influencée par divers facteurs, dont des facteurs sociaux tels que les connaissances, les perceptions et les comportements de la population ciblée. Elles peuvent également avoir des impacts parallèles non désirés, par exemple sur l’environnement et l’économie, et ces derniers peuvent s’opposer aux bénéfices des interventions jusqu’à remettre en cause la pertinence de leur mise en œuvre. Aussi, ces facteurs sociaux et les impacts des interventions sont susceptibles de varier selon la population ciblée et en fonction du contexte épidémiologique et social. L’objectif de cette thèse était donc d’étudier les principaux facteurs sociaux et enjeux d’importance à considérer pour évaluer l’efficacité et prioriser des interventions de prévention pour la maladie de Lyme dans deux populations exposées à des contextes différents, notamment en ce qui concerne leur situation épidémiologique, soient au Québec, où l’incidence de la maladie de Lyme est faible mais en émergence, et en Suisse, où elle est élevée et endémique depuis plus de trois décennies. L’approche choisie et le devis général de l’étude sont basés sur deux modèles théoriques principaux, soient le modèle des croyances relatives à la santé et celui de l’aide à la décision multicritère. Dans un premier temps, les facteurs associés à la perception du risque pour la maladie de Lyme, c’est-à-dire l’évaluation cognitive d’une personne face au risque auquel elle fait face, ont été étudiés. Les résultats suggèrent que les facteurs significatifs sont différents dans les deux régions à l’étude. Ensuite, l’impact des connaissances, de l’exposition, et des perceptions sur l’adoption de comportements préventifs individuels et sur l’acceptabilité des interventions de contrôle des tiques (acaricides, modifications de l’habitat, contrôle des cervidés) a été comparé. Les résultats suggèrent que l’impact des facteurs varierait en fonction du type du comportement et des interventions, mais que la perception de l’efficacité est un facteur commun fortement associé à ces deux aspects, et pourrait être un facteur-clé à cibler lors de campagnes de communication. Les résultats montrent également que les enjeux relatifs aux interventions de contrôle des tiques tels que perçus par la population générale seraient communs dans les deux contextes de l’étude, et partagés par les intervenants impliqués dans la prévention de la maladie de Lyme. Finalement, un modèle d’analyse multicritère a été développé à l’aide d’une approche participative pour le contexte du Québec puis adapté pour le contexte suisse et a permis d’évaluer et de prioriser les interventions préventives selon les différentes perspectives des intervenants. Les rangements produits par les modèles au Québec et en Suisse ont priorisé les interventions qui ciblent principalement les populations humaines, devant les interventions de contrôle des tiques. L’application de l’aide à la décision multicritère dans le contexte de la prévention de la maladie de Lyme a permis de développer un modèle décisionnel polyvalent et adaptable à différents contextes, dont la situation épidémiologique. Ces travaux démontrent que cette approche peut intégrer de façon rigoureuse et transparente les multiples perspectives des intervenants et les enjeux de la prévention relatifs à la santé publique, à la santé animale et environnementale, aux impacts sociaux, ainsi qu’aux considérations économiques, opérationnelles et stratégiques. L’utilisation de ces modèles en santé publique favoriserait l’adoption d’une approche « Une seule santé » pour la prévention de la maladie de Lyme et des zoonoses en général.

Several prevention strategies exist and include strategies at the individual level, such as wearing protective clothing, and at the population level, including tick control interventions in the environment. The effectiveness of these strategies can be influenced by various factors, including social factors such as knowledge, perceptions and behaviors of the target population, and by their potential impacts on various sectors such as on the environment and on the economy. Also, these social factors and impacts are likely to vary according to the epidemiological and social context of the target population. The objective of this thesis was to study the main social factors and issues of importance to consider for the prioritization of preventive interventions for Lyme disease in two populations living in different contexts, particularly with regard to their epidemiological situation, that is in Quebec, where the incidence of Lyme disease is low, but emerging, and Switzerland, where it is high and has been endemic for more than three decades. The approach and the design of this study were based on two main theoretical models, namely the Health Belief Model and the multicriteria decision analysis approach. Factors associated with risk perception, that is the cognitive assessment of a person facing a risk, for Lyme disease were studied initially in the target populations. The results suggest that factors significantly associated with a high level of risk perception are different in the two regions. Then, the impact of knowledge on Lyme disease, exposure, perceptions on the adoption of individual preventive behavior and on the acceptability of tick control interventions were compared. The data suggest that the impact of these factors varies according to the type of behavior and interventions, but that the perception of efficacy is a common factor strongly associated with both aspects, and could be targeted in communication campaigns. The results also show that issues related to tick control interventions as perceived by the participants are common in both contexts, and shared by the stakeholders involved in the prevention of Lyme disease. Finally, a multi-criteria analysis model was developed using a participatory approach for the Quebec context, adapted to the Swiss context and allowed to prioritize preventive interventions according to different stakeholder perspectives. Rankings produced by these models prioritized interventions that primarily target human populations in preference to tick control interventions. Applying the multi-criteria decision analysis approach in the context of Lyme disease prevention led to the development of a versatile decision model that can be adapted to different contexts, including the epidemiological situation. These studies show that this approach can offer a rigorous and transparent way to integrate the multiple perspectives of stakeholders and issues of prevention including those relating to public health, animal and environmental health, social impacts, as well as economic, operational and strategic considerations. Their use in public health practices could facilitate the adoption of a practical and applied “One health” approach to Lyme disease and other zoonosis prevention.

Conclusion. The significance of risk perception in predicting behavioral intention, hence actual future behaviors, is therefore evident. Conditional measures need to be used. HIV prevention can employ conditional risk perception approaches. Health behavioral theories can be strengthened by using such conditional measures on risk perceptions. The results add to this new and growing area of risk behavior research. / Introduction. Risk perception, a core element of key health behavioral theories and health interventions, is assumed to motivate people to avoid risk behaviors. Mixed findings however prevail in the literature due to methodological issues. Many of such studies are cross-sectional, using global risk perception measures that do not condition on type of risk behavior or partnership which may affect the level of risk. / Male injecting drug users (IDU) are driving the HIV epidemic in China and bridge HIV transmission to non-IDU female populations; they may be at risk of both unprotected sex and syringe sharing. HIV prevention targeting male IDU is greatly warranted and would benefit from understanding of the relationships between risk perceptions and behaviors, in the context of health behavioral theories such as the Health Action Process Approach (HAPA) model, which had not been applied to studies targeting IDU. / Objectives. This study refined the concepts and measures of HIV-related risk perception, conditioning on different types of behaviors and partners, and extended it to include others-directed risk perceptions. The relationship between such conditional risk perception measures and both prior risk behaviors and behavioral intention to avoid sex-related and drug-related risk behaviors in the future were investigated and were compared to those involving global unconditional risk perception measures. The nature of the aforementioned relationships, being motivational or reflective was investigated. A longitudinal component validated the predictive power of behavioral intention over actual future behaviors. / Results. Almost 90% of the respondents had had unprotected sex though <20% shared syringes with others in the last 6 months. Prior syringe sharing but not unprotected sex in the last 6 months was significantly associated with global unconditional risk perception measures. The picture is totally different when risk perception measures conditioned on type of sex partner and unprotected sex or syringe sharing were used instead of the global measures---higher levels of the conditional risk perception measures were significantly associated with higher levels of behavioral intention for consistent condom use and avoidance of syringe sharing, thus supporting the motivational hypothesis. Conditional others-directed risk perceptions (perceived risk of transmitting HIV to others via unprotected sex and syringe sharing) were also associated with the aforementioned behavioral intentions to avoid risk behaviors. A pilot longitudinal study showed that behavioral intentions strongly predict actual future behaviors. Other HAPA-based variables such as self-efficacy and outcome expectancies had predictive effects on behavioral intentions, independent from those of risk perceptions. / Subjects and methods. A total of 456 sexually active male IDU were recruited from Dazhou, Sichuan and Hengyang, Hunan, via snowball sampling. With informed consent, anonymous face-to-face interviews were conducted by trained and experienced staff of the local CDC in privacy settings. / Tsui, Hi Yi. / Adviser: Joseph Lau. / Source: Dissertation Abstracts International, Volume: 72-04, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (leaves 118-130). / Electronic reproduction.

Die dauerhafte Reduktion der von Menschen verursachten Emissionen ist eine der zentralen Herausforderungen unserer Zeit. Eine Strategie zur Reduzierung von Emissionen im Mobilitätssektor sind elektrisch betriebene Fahrzeuge, die je nach Typ teilweise oder vollständig mit Strom angetrieben werden. Für die Verkehrspsychologie stellt sich nun die Frage, ob und wie schnell sich Fahrer an die Nutzung von Elektrofahrzeugen gewöhnen und welche Herausforderungen sich aus Nutzersicht ergeben. Anhand von Studien mit vollelektrischen Fahrzeugen wurden in der vorliegenden Arbeit zwei grundlegende Eigenschaften von Elektrofahrzeugen aus psychologischer Perspektive untersucht: Zum einen verfügen Elektrofahrzeuge über eine Rekuperationsfunktion, mit der es möglich ist, in Verzögerungsvorgängen kinetische in elektrische Energie umzuwandeln, also Energie rückzugewinnen und damit letztlich die Emissionen zu reduzieren. Zum anderen beschränkt sich die mögliche Emissionsreduktion von Elektrofahrzeugen nicht nur auf den CO2-Ausstoß, sondern betrifft auch die Geräuschentwicklung dieser Fahrzeuge. Fahrzeuge mit Elektroantrieb emittieren weniger Geräusche, was einerseits die Lärmbelastung durch Straßenverkehr reduzieren kann, zum anderen aber auch zu Bedenken z.B. blinder Verkehrsteilnehmer geführt hat. Gerade bei geringen Geschwindigkeiten sind Elektrofahrzeuge schlechter wahrnehmbar und dadurch eine potentielle Gefahr für andere Verkehrsteilnehmer. Das erste Ziel der vorliegenden Dissertation bestand darin, die Auswirkungen einer über das Gaspedal gesteuerten Rekuperation aus verkehrspsychologischer Perspektive zu untersuchen. Die zur Nutzung der Rekuperation nötigen motorischen Fertigkeiten müssen erlernt und in unterschiedlichen Verkehrssituationen angewandt werden. Basierend auf dem Power Law of Practice (Newell & Rosenbloom, 1981) wurde der Fertigkeitserwerb bei der Nutzung der Rekuperationsfunktion eingehend betrachtet. Anhand von Fahrzeugdaten lassen sich eine sehr steile Lernkurve und damit ein kurzer Adaptationsprozess zeigen, der mit einer Powerfunktion beschrieben werden kann. Bereits innerhalb der ersten gefahrenen Kilometer nehmen die Anzahl der konventionellen Bremsmanöver und ihr zeitlicher Anteil an der gesamten Verzögerung rapide ab. Das zweite Ziel der vorliegenden Dissertation war, die Auswirkungen der geringeren Geräuschemission auf das Verkehrsgeschehen zu prüfen. Dies erfolgte jedoch nicht, wie in anderen Studien bereits dargestellt, aus Fußgängerperspektive, sondern aus der Fahrerperspektive. Da die Fahrer gerade in der Anfangsphase eine zentrale Rolle bei der Entschärfung geräuschbedingter kritischer Situationen spielen, soll die Arbeit dazu beitragen, diese Forschungslücke zu schließen, um eine umfassendere Bewertung der Geräuschthematik bei Elektrofahrzeugen zu ermöglichen. In Anlehnung an Deerys (1999) Modell zu Fahrerreaktionen auf potentielle Gefahren, wurden Risikowahrnehmung (risk perception) und Gefahrenwahrnehmung (hazard perception) als entscheidende Determinanten der Fahrerreaktion auf geräuschbedingte Gefahrensituationen identifiziert. Was die Risikowahrnehmung betrifft, so konnte gezeigt werden, dass diese sich mit zunehmender Erfahrung verändert. Risiken aufgrund der Geräuscharmut werden als weniger bedrohlich, das leise Fahren zunehmend als Beitrag zum Komfort gewertet. Zusätzlich wurden im Rahmen der Dissertation Situationen im Straßenverkehr näher untersucht, die aufgrund der Geräuscharmut von Elektrofahrzeugen auftraten. Darauf aufbauend wurde ein Katalog von geräuschbedingten Szenarien erstellt, der als empirische Grundlage für die nähere Betrachtung der Gefahrenwahrnehmung von Fahrern diente. Ergebnisse daraus resultierender Experimente zur Detektion von geräuschbedingten Gefahren (hazard detection tasks) zeigten, dass die individuelle Erfahrung mit Elektrofahrzeugen offenbar lediglich eine untergeordnete Rolle bei der Erkennung und Reaktion auf geräuschbedingte Gefahren spielt. Erfahrene Fahrer von Elektrofahrzeugen unterschieden sich nur marginal von unerfahrenen Fahrern in der Reaktion in und der Bewertung von geräuschbedingten Gefahrensituationen, was darauf hindeutet, dass geräuschbedingte Gefahrensituationen auch von Fahrern ohne extensive Erfahrung mit Elektrofahrzeugen bewältigt werden können. Das dritte, übergreifende Ziel der Dissertation bestand darin, die Bedeutung beider Eigenschaften für die Nutzerakzeptanz zu untersuchen. Neben der Untersuchung momentan existierender Barrieren (z.B. Reichweite, Preis, Batterielebensdauer), die eine weitreichende Adoption von Elektrofahrzeugen erschweren können, ist es ebenso wichtig, solche Eigenschaften zu identifizieren, die sich positiv auf das Nutzererleben auswirken. Sowohl die Rekuperation, als auch die Geräuscharmut spielen eine wichtige Rolle in der Nutzerbewertung, da beide Eigenschaften als zentrale, individuell erlebbbare Vorteile von Elektrofahrzeugen beurteilt werden. Im Hinblick auf die Geräuschemission lässt sich konstatieren, dass diese mit zunehmender Erfahrung des Fahrers fast ausschließlich als Vorteil statt als Barriere von Elektrofahrzeugen gewertet wird. Eine bemerkbare, über das Gaspedal gesteuerte Rekuperation scheint als Teil des Fahrererlebens ebenfalls eine zentrale Rolle in der Bewertung zu spielen. Ein hohes Maß an Nutzerakzeptanz und Vertrauen in das System unterstreichen die positive Evaluation einer solchen Funktionalität. Aus verkehrspsychologischer Sicht haben die angeführten Eigenschaften von Elektrofahrzeugen Auswirkungen auf verschiedene Teilaufgaben der Fahrzeugführung. So sind nicht nur motorische Fertigkeiten in der Pedalnutzung (Stabilisierungsbene) erforderlich, sondern auch komplexere kognitive Prozesse, wie z.B. der Umgang mit möglichen Gefahrensituationen aufgrund der geringen Geräuschemission (Bahnführungsebene). Insgesamt weisen die Ergebnisse der Dissertation darauf hin, dass Herausforderungen aufgrund beider oben genannten Fahrzeugeigenschaften gemeistert werden können. Zusätzlich zeigen die Ergebnisse, dass beide Eigenschaften von den Nutzern als willkommene Aspekte der technologischen Innovation geschätzt werden und somit zur allgemeinen Akzeptanz von Elektrofahrzeugen beitragen können. Da auch andere Fahrzeugkonzepte mit elektrischem Antriebsstrang diese beiden Eigenschaften aufweisen, lassen sich die gefundenen Ergebnisse auf andere Fahrzeugtypen übertragen.

八八水災於2009年重創南台灣，遷村易安全地而居成為政府防災風險管理的工作重要任務之一，但政策執行時卻遭遇眾多原住民部落不願離家的抗拒，我們由此現象關注到原住民族群特殊的所在依附感，欲透過所在依附感的角度，探討其與風險知覺、防災準備行為、心理健康及心理症狀間的關係。過去文獻對防災準備行為的影響因子並無一致定論，本研究除檢驗災難風險知覺與防災準備行為的關係外，同時認為所在依附感可能對風險知覺與防災準備行為有所影響。由於關切八八原住民災民於災後的心理反應，我們將所在依附感、災難風險知覺、防災準備行為視為災後心理反應的保護因子，檢驗三保護因子分別對生活滿意度、創傷後壓力疾患症狀、憂鬱症狀的影響。本研究於災後約12-15個月，以563名八八災後回鄉居住原住民倖存者為樣本，使用所在依附量表、水災防災準備行為量表、創傷後壓力診斷量表、中文版流行病學研究中心憂鬱量表、TLSA調查中的生活滿意度指標等量表蒐集資料。結果顯示：1. 防災準備方面：生計依附感能夠顯著正向預測防災準備行為、風險可能性與風險擔心度均負向預測防災準備行為，生計依附感同時在風險知覺與防災準備行為間扮演中介變項角色，宗譜傳承及認同向度依附對防災準備行為無顯著預測力；2. 生活滿意度方面：生計依附感對生活滿意度具顯著正向預測力，但此預測力在同時考量防災準備行為時，則下降至不顯著，兩向度風險知覺、防災準備行為均無法顯著預測生活滿意度；3. PTSD症狀方面：三向度所在依附感、兩向度風險覺知、防災準備行為均無法顯著預測PTSD症狀；4. 憂鬱症狀方面：防災準備行為對憂鬱症狀具顯著負向預測力，三向度所在依附感、兩向度風險知覺均對憂鬱症狀不具顯著預測力。 / The aim of this study is to examine relationships between place attachment, risk perception, flood preparedness, mental health, and psychological symptoms after 88 flood disaster in 2009. In particular, investigation focused on three dimensions of place attachment, viz. genealogical, economic, and identity-related. Contextualized scales for place attachment, risk perception, and flood preparedness were developed. Besides, PDS, CES-D, Life Satisfaction Scale were also used in this study. Validity and reliability of the scales were established. Data were collected 12-15 months after the flood from 537 survived and still living in the same homeland aboriginals. Results show, 1. Flood preparedness: economic place attachment predicts flood preparedness positively; two dimensions of risk perception predict flood preparedness negatively, while economic place attachment plays a role as mediator in flood preparedness. 2. Life satisfaction: economic place attachment slightly predicts life satisfaction positively under no consideration to flood preparedness, whereas overall place attachment, risk perception, and flood preparedness have no influence on life satisfaction. 3. PTSD: Neither place attachment, risk perception, nor flood preparedness is related to PTSD. 4. Depression: flood preparedness shows negative impact on depression symptoms; however, place attachment and risk perception do not.

The research area of this work is online threat awareness within an information security context. The research was carried out on secondary school learners at boarding schools in Grahamstown. The participating learners were in Grades 8 to 12. The goals of the research included determining the actual levels of awareness, the difference between these and self-perceived levels of the participants, the assessment of risk in terms of online behaviour, and the determination of any gender differences in the answers provided by the respondents. A review of relevant literature and similar studies was carried out, and data was collected from the participating schools via an online questionnaire. This data was analysed and discussed within the frameworks of awareness of threats, online privacy social media, sexting, cyberbullying and password habits. The concepts of information security and online privacy are present throughout these discussion chapters, providing the themes for linking the discussion points together. The results of this research show that the respondents have a high level of risk. This is due to the gaps identified in actual awareness and perception, as well as the exhibition of online behaviour patterns that are considered high risk. A strong need for the construction and adoption of threat awareness programmes by these and other schools is identified, as are areas of particular need for inclusion in such programmes. Some gender differences are present, but not to the extent that, there is as significant difference between male and female respondents in terms of overall awareness, knowledge and behaviour.

Além disso, o formato padrão utilizado para comunicar os riscos é, geralmente de difícil compreensão e de pouca ajuda na tomada da decisão de investimento, pois a mencionada padronização, raramente leva em consideração os diferentes níveis de conhecimento dos investidores sobre finanças (Sachse, Jungermann, & Belting, 2012, v. 33, p. 438, tradução nossa). Alinhada a isso, a presente pesquisa utiliza questionário baseado na Teoria do Paradigma Psicométrico, para investigar as percepções de risco entre especialistas e investidores leigos sobre seis produtos financeiros. Baseado no elevado conhecimento sobre investimentos que possuem, os Certified Financial Planners foram escolhidos como grupo de controle para comparar as percepções de risco da categoria profissional melhor remunerada no Brasil, qual seja a dos médicos da Grande São Paulo (IBRE, 2009). Testes t para diferença de médias foram feitos para avaliar as percepções entre gêneros e os cinco construtos de risco, respectivamente, relacionados à volatilidade, ao desconhecimento, a desconfiança, a adversidade e as falhas regulatórias; os testes mostraram que são distintas as percepções de risco entre CFPs e médicos, com resultados muitas vezes contrários aos indicados pela literatura, assim como a maior percepção de risco entre as mulheres somente para os construtos relacionados às falhas regulatórias e desconfiança nos consultores de investimento, instituições financeiras e órgãos reguladores. O estudo mostra, ainda, que estão negativamente correlacionadas as percepções do benefício/retorno com os construtos desconfiança e falhas regulatórias somente entre os médicos, e que há diferenças de percepção importantes para o Tesouro Direto e PGBL/VGBL entre as duas categorias profissionais. Dentre os resultados encontrados destacam-se as diferentes percepções de risco sobre os construtos falhas da regulamentação e desconfiança, sugerindo que iniciativas de educação voltadas ao investidor podem não surtir o efeito esperado em razão de serem patrocinadas exatamente por instituições vistas com suspeição pelos investidores. O estudo conclui atribuindo à comunicação o papel determinante do sucesso na relação com o investidor e a necessidade que ela seja construída a partir das percepções de risco e níveis de familiaridade com investimentos dos consumidores. / Most individual investors may be overwhelmed by this vast amount of information and by its abstract nature. Furthermore, this way of informing about risk might be hardly helpful when making a particular investment decision, because this kind of standardized information neglects different levels of experience and financial literacy of the clients (Sachse, Jungermann, & Belting, 2012, v. 33, p. 438). Aware of this, this research paper will use a questionnaire in Psychometric Paradigm Theory to investigate risk perceptions among specialists and lay investors of six financial products. Certified Financial Planners were selected as the control group to assess how risk perceptions of the best-paid category in Brazil, compounded by physicians in São Paulo Metropolis (IBRE, 2009). T Tests about average differences were taken to assess gender perceptions and the five risk constructors associated with volatility, lack of knowledge, mistrust, adversity and regulatory failures; tests showed that risk perceptions are different between CFPs and physicians, with some results contradicting literature, as well as a greater perception of risks among women only to risk constructs related to regulatory failures and mistrust in investment advisors, financial institutions and regulatory bodies. The study also shows that correlations between benefit/return and constructs distrust and regulatory failures are negative only among physicians, and that there are significant perceptual differences about Tesouro Direto and PGBL/VGBL among the two professional categories. Different risk perceptions about the lack of regulation, as well as distrust, suggest that investor education initiatives may not have the expected effect, since they are sponsored by the same institutions of which investors are suspicious. Finally, the study says consumer perceptions of risk and their level of familiarity with investments are crucial, and attributes to communication the role for determining success in the relationship with investors.
