Full textAbstract:
Cardiovascular disease (CVD) including coronary artery disease and stroke is a significant health problem in Japan regardless of well established health care and insurance system and various public campaigns and exhibitions in the contemporary Japanese society. Higher and increasing prevalence and incidence of well-known risk factor of CVD may contribute to increasing mortality and morbidity of CVD in the future. However, limited knowledge was available for understanding perceptions of risk for CVD among Japanese adults. This grounded theory study aimed to explore social psychological process in perception of risk for CVD among Japanese adults.There were a total of 26 individuals participated in this study. Participants consisted of 19 Japanese adults with at least one CVD risk factor and 7 Japanese health care providers residing or working in which a consistently high mortality rate of CVD in both men and women.The theory grounded from the data was a process to avoid serious physical, emotional, social, and financial suffering as a consequence of developing CVD or of leaving it untreated and a process to maintain a good relationship with risk for CVD among Japanese adults with CVD risk factors. This grounded theory was consisted of the central concept of perceived risk for CVD, which defined as fear, threats, sorrow, worries, and/or anxiety for possible adverse impacts on their life living with their family and suffering for loss of independence and quality of life consequent upon CVD. This central concept was followed by actions to avoid these adverse and excruciating consequences of CVD including changing behavior, taking measures to manage CVD risk, and continually evaluating their condition. Factors contributed to perception of risk for CVD among Japanese adults were seriousness and severity of consequences of CVD, susceptibility, proneness, and possibility to develop CVD, and Japanese specific contextual factors.This study may contribute to appropriately addressing perception of risk for CVD and behavior change among Japanese adults with risk factors for CVD within the unique social, cultural context of Japan. The results of this study could apply to better nursing practice for CVD risk management and health promotion in Japan.

Shakeri, Shadi. "Modeling Information Seeking Under Perceived Risk." Thesis, University of North Texas, 2018. https://digital.library.unt.edu/ark:/67531/metadc1404510/.
Full textAbstract:
Information seeking and information avoidance are the mechanisms humans natural used for coping with uncertainties and adapting to environmental stressors. Uncertainties are rooted in knowledge gaps. In social sciences, the relationship between knowledge gaps and perceived risk have received little attention. A review of the information science literature suggests that few studies have been devoted to the investigation of the role of this relationship in motivating information-seeking behavior. As an effort to address the lack of theory building in the field of information science, this study attempts to construct a model of information seeking under risk (MISR) by examining the relationships among perceived risk, knowledge gap, fear arousal, risk propensity, personal relevance, and deprivation and interest curiosity as antecedents to motivation to seek information. An experimental approach and a scenario-based survey method are employed to design the study. Partial least square structural equation modeling (PLS-SEM) analysis was conducted to test the relationships in the proposed model. Perceived risk was found to be a highly significant predictor of information seeking in moderately high-risk situations. Similarly, personal relevant has a significant negative effect on perceived risk and its interaction with knowledge gap motivates information seeking.

Full textAbstract:
Magister Psychologiae - MPsychUsing the literature on Baumrind's theory of Parenting Styles and how perceptions of these are associated to adolescent at-risk behaviour, this study set out to examine whether any parenting style increased or decreased adolescent substance use. The central aim of this study was to examine the association between perceived parenting styles and adolescent substance use. To further this, 239 grade 10 and 11 adolescent participants were drawn from 3 schools in Mitchell's Plain, a suburb in the Western Cape (with permission granted from the Education Department). This particular suburb was chosen due to the high rates of substance use and substance related crime within the area. A quantitative research design was implemented within this study. The participants were required to complete the Drug Use Disorders Identification Test (DUDIT), a questionnaire aimed at measuring drug use, and the Parental Authority Questionnaire (PAQ), aimed at measuring perceived parenting styles and a Biographical Questionnaire to provide additional information. Informed consent was obtained and the confidentiality of the schools and participants were protected. Data analysis was conducted using SPSS, a data analysis programme available at the University of the Western Cape. Results show that substance use reduction was significantly related to a perceived authoritative parenting style. However, no significant relationships could be found between perceived permissive and authoritarian parenting style. Significant difference was found in the results obtained for male and female adolescents, with males generally appearing to use more substances. It can be concluded that perceived authoritative parenting styles have an important role to play in the prevention of adolescent substance abuse.

Full textAbstract:
Purpose - The purpose of this study is to investigate behavioral factors influencing investment intentions. Design/methodology/approach – A descriptive quantitative study was conducted utilizing an online questionnaire with a total of 121 respondents. Findings - The results of the study indicated that Subjective Norm, Perceived Behavioral Control, and Perceived Consumer Effectiveness are positively related to Intention to Invest. Attitude and Perceived Risk did not reach statistical significance and no conclusions could therefore be drawn regarding the concepts. Research limitations/implications - The greatest limitation of the study is that it measures intention and not actual behavior which could be of more value, both from a theoretical and managerial perspective. The implication of the study is that it contributes to the Socially Responsible Investment literature from the intentional perspective and that it considers Generation Y, two aspects that have previously been neglected. The study further provides companies operating in SRI industry with a framework to use when acquiring customers within Generation Y. Originality/value - As recent Socially Responsible Investment research has focused almost exclusively on financial performance this study offers value in that it instead explains behavioral factors influencing the Intention to Invest. It further focuses on Generation Y which is the upcoming generation when it comes to investing that has to a large extent been neglected in the SRI literature.

Liu, Sheng, and Bobo Tiger. "Antecedents of buying intention towards bio-cotton clothing : A quantitative study among young business students at USBE." Thesis, Umeå universitet, Företagsekonomi, 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-136479.
Full textAbstract:
Due to the growing involvement of external stakeholders including pressure groups such as Greenpeace, sustainability issues have increasingly become a focus point in the business sector. Thereby, many businesses began to integrate sustainability into their corporate mission and vision. Similar to fast food consumption, fast fashion consumption has decreased well-being of both nature and humans. With the goal of reducing harmful impact on people and planet, apparel and fashion firms such as C&A, H&M, and Nike have been gradually shifting the use of conventional cotton to bio-cotton in their production of clothing. The aim of the present thesis is therefore to investigate the influence of different factors on purchasing intention of bio-cotton clothing among young business students. In connection to this, the research question of the present study is formulated as follows: “What kind of impacts do attitude, social norm, perceived efficacy of consumer, perceived availability as well as functional, monetary, and psychological risk have on the purchase intention of bio-cotton clothing among young business students?” The present study was conducted quantitatively by using online survey method. The survey was distributed to a random sample of 220 young business students at Umeå School of Business and Economics (USBE). The research model of this study comprises seven hypotheses. Each hypothesis is assigned with a unique independent variable and a dependent variable (i.e. purchase intention). All the constructs are derived from the Theory of Planned Behaviour as well as from the Theory of Perceived Risk. Following a multiple linear regression analysis, it was revealed that independent variables including attitude, social norm, perceived efficacy of consumer, and perceived availability significantly affect the purchase intention. All influencers except perceived availability was found to have a negative influence on purchase intention. Although none of the constructs from the Theory of Perceived Risk was found to significantly affect purchase intention, a significant quantity of variance in the purchase intention was explained by all independent variables combined. This contributes to the current research gap since numerous studies have focused on the behavioural intention of organic food rather than bio-cotton clothing. This study’s findings provide insights to businesses that intend to market their bio-cotton clothing among young business students. Since the availability of bio-cotton clothing was found to be low, managers are advised to increase the visibility and benefits of such products by using online and offline communication instruments. Policy makers, especially those from developed countries, are advised to support informational campaigns to transform consumer behaviour.

Christopher, Juleen L. "An Examination of Dimensions of Perceived Behavioral Control Regarding Genetic Counseling and Testing for BRCA 1 and BRCA 2 in African-American Women at Moderate to High-Risk for Breast Cancer." Diss., Virginia Tech, 2010. http://hdl.handle.net/10919/77364.
Full textAbstract:
Breast cancer affects thousands of women each year and among those diagnosed, African-American women (AAW) make up a significant proportion that are diagnosed with early onset disease, have larger tumors, greater lymph node involvement, higher mortality and lower survival rates. Studies examining factors associated with greater breast cancer morbidity and mortality in this group have suggested that they may differ from Caucasian women in terms of certain risk factors for breast cancer; however, other evidence suggests that the risk of developing breast cancer is similar among African-American and Caucasian women who have a family history of breast cancer. As such, access to genetic counseling and testing (GC/T) services would be an important part of cancer control for this group but in this fast moving area of medicine African-American women are being "left behind".
It is unclear why AAW have not readily adopted these preventive services. In light of the paucity of evidence regarding explanations of underuse, it is possible that important factors such as perceived behavioral control (PBC) in the Theory of Planned Behavior may help explain African-American women's participation in genetic counseling and testing for BRCA 1/2. The goals of this mixed methods study were twofold; first, to explore levels of perceived behavioral control and general motivations regarding genetic counseling and testing for BRCA 1/2 in African-American women at moderate to high-risk for breast and ovarian cancer and second, to explore the dimensionality of the perceived behavioral control construct from the Theory of Planned Behavior (TPB) and its utility in understanding underuse of BRCA 1/2 genetics services in this group. African-American women are being "left behind".
Overall, women had high levels of perceived behavioral control, low knowledge and positive attitudes towards genetic counseling and testing for BRCA 1/2. Results from the principal components analysis lent support for the dimensionality of the perceived behavioral control construct suggesting that it indeed could be thought of as made up of the constructs perceived control [P-C] and perceived difficulty [P-D]. Only perceived control was found to be associated with genetic testing intentions suggesting that it was a better predictor. Neither scale was associated with genetic counseling intentions. African-American women are being "left behind".
Future research should focus on educational efforts geared towards highlighting the utility of genetic counseling in addition to genetic testing for BRCA 1/2. Theoretical implications include using two measures to assess aspects of perceived behavioral control (perceived difficulty [P-D] and perceived control [P-C]) instead of one PBC measure. Additionally, studies using the TPB model should include the constructs of spirituality and knowledge when trying to understand underuse of BRCA 1/2 genetic services in African-American women at moderate to high-risk for breast cancer. African-American women are being "left behind".Ph. D.

Severe, Marie Sandra. "Association Between Childhood Sexual Abuse and HIV-Related Risk Factors for HIV-Positive Haitian Women." FIU Digital Commons, 2015. http://digitalcommons.fiu.edu/etd/2279.
Full textAbstract:
Childhood sexual abuse (CSA) is one of the least studied HIV-related risk factors in Haiti although research in the United States and Europe has clearly established the link between childhood trauma and HIV risk behaviors. Understanding the role and impact of CSA on HIV-positive Haitian women is likely to strengthen future HIV prevention and treatment efforts aimed at this vulnerable group.
The current study was a cross-sectional examination of baseline data collected during a randomized trial of a cognitive-behavioral stress management (CBSM) intervention in Haiti. The purpose of this study was to analyze the association between CSA and sexual risk behaviors, alcohol use, and social support in a group of Haitian women, ages 17-55 (n=229), who are HIV-positive alcohol users living in Haiti. The outcomes investigated were the respondents’ level of exposure to CSA and their current HIV-related risk factors. The Theory of Gender and Power provided the theoretical framework for variable selection and associative exploration. Statistical tests included descriptive analyses, chi-square tests, analysis of variance (ANOVA), and correlations.
Results showed that women who were exposed to some level of sexual abuse during childhood had less favorable attitudes towards condom use than women who reported no exposure to sexual abuse during childhood [F(2, 217) = 5.10, p = .007]. There were no differences between exposure groups for the remaining sexual risk behaviors: multiple partners, knowledge of HIV, and sexual self-efficacy. Women who were exposed to CSA also reported higher levels of alcohol use than reported by the women in the non-exposure group. Finally, there were no differences between exposure groups for social support.
Group differences in attitudes towards condom use and levels of alcohol use among HIV-positive Haitian women demonstrate that HIV-positive individuals have different past and present experiences that affect their current beliefs and behaviors. Examining women at the beginning of their diagnosis for childhood trauma and providing targeted interventions for coping with that trauma presents a valuable research opportunity. The findings of the current study suggest that more research is required to understand the association between CSA and HIV-related risk factors in this subset of the HIV-positive population.

The Cue Utilization Theory establishes that all products are made of multiples cues that may be seen as surrogates for the intangible attributes that make up any given product. However, the results of many years of research have yet yielded little consensus as to the impact generated by the use of such cues. This research aims to contribute to the discussion about the importance of intrinsic cues by investigating the effects that the use of product cues that confirm the product claim may have on Claim Credibility (measured through Ad Credibility), and also on consumers’ Purchase Intention and Perceived Risk toward the product. An experiment was designed to test such effects and the results suggest the effects of the use of Claim Confirming Product Cues depend on consumer’s level of awareness about such cue, and that when consumers are aware of it, Ad Credibility and Purchase Intention increase, as Perceived Risk decreases. Such results may have implications to academicians and practitioners, as well as may provide insights for future research.

Mestrado em MarketingOs canais electrónicos, fruto do desenvolvimento tecnológico, vieram transformar por completo o relacionamento dos Bancos com os seus clientes, nos últimos anos. O canal de mobile banking, é a mais recente aposta dos Bancos em termos de canais electrónicos apresentando como principais vantagens a redução de custos e a ubiquidade, permitindo aos clientes aceder ao banco em qualquer hora e/ou local, a partir de um smartphone ou tablet com ligação à internet. No entanto, apesar das vantagens de utilização, a taxa de adopção das Apps bancárias fica muito aquém das expectactivas, pelo que se torna crucial conhecer os factores que influenciam o processo de decisão. É nesta perspectiva que surge esta investigação. Construiu-se um modelo de pesquisa resultante da combinação da Teoria da Difusão da Inovação, Risco Percebido, Confiança e características sócio demográficas. As hipóteses formuladas foram testadas, no âmbito de uma análise quantitiva, tendo por base 439 questionários recolhidos online, durante a primeira semana de Setembro de 2012. Concluiu-se que a Compatibilidade e a Complexidade são factores que influenciam directa e positivamente a adopção, de acordo com a literatura existente. Contrariamente às evidências empíricas mais consensuais, a Vantagem Relativa apresentou-se como factor inibidor e o Risco Percebido tal como a Confiança foram considerados insignificantes. O Sexo, a Idade, a Situação Profissional e o Rendimento Anual Líquido revelaram-se predictores de potenciais utilizadores das Apps bancárias.
Electronic channels, children of technological development, arrived to change the landscape of bank-client relationships completely, in the last few years. The mobile banking channel represents the banking market’s most recent bet in this field, an evolution over SMS exchange, combined with WAP, leading to banking Apps. This channel’s main advantages are cost reduction and ubiquity, which allows clients to access their accounts anywhere, at any time, from a mobile phone or tablet, provided there’s an internet connection. Despite all the advantages, the acceptance rate of mobile banking Apps has been casting a shadow over previous forecasts, making it crucial to understand what factors could be influencing the decision-making process. This study aims to shed some light on the subject. For that purpose, a research model has been put together, which combines Innovation Diffusion Theory, Perceived Risk, Trust and Social demographic aspects. The hypotheses formulated in this study have been tested, quantitatively, against 439 on-line surveys, during the first week of September, 2012. It was concluded that Compatibility and Complexity (or lack of thereof) are variables that impact positively and directly in the acceptance of mobile banking Apps, which is in accordance with existing literature. Against consensual empiric certainties, Relative Advantage proved to be an inhibiting factor and both Perceived Risk and Trust have been deemed insignificant. Gender, Age, Job Situation and Net Annual Income revealed themselves as the predictors of potential users of banking Apps.

Full textAbstract:
The aims of the current study are to examine the relation of risk taking behaviors (RTBs) with perceived risk, perceived benefit, and impulsivity and also to investigate the moderator role of impulsivity on the relationships between engagement in RTBs and the predictors of the engagement in RTBs (i.e. perceived risk and benefit) after controlling the effects of age, gender, and self esteem. In order to measure engagement in RTBs, perceived risk, and perceived benefit, Modified Risk Involvement and Perception Scale (Özmen, 2006) was adapted to Turkish culture in Study 1 by using Middle East Technical University (METU) students. The sample of Study 2 was composed of 234 METU students and a questionnaire set including demographic information sheet, Modified Risk Involvement and Perception Scale (M-RIPS) (Ö

et al., 2008), and Rosenberg Self Esteem Scale (RSES) (Rosenberg, 1965) was administered. Multiple hierarchical regression analysis was conducted with perceived risk, perceived benefit, and impulsivity as independent variables and engagement in RTBs as the dependent variable. The findings suggested that perceived risk was negatively whereas perceived benefit and impulsivity was positively related to risk taking behaviors. Moreover, as compared to perceived risk, perceived benefit was a more powerful predictor of RTB. However, it was not found any moderator role of impulsivity on the relationships between engagement in RTBs and its predictors. The strengths and limitations, as well as implications of the findings were discussed.

“Interpersonal needs and suicide risk in a sample of elderly patients”
The aim of this study is to test the contribution of interpersonal needs - thwarted belongingness and perceived burdensomeness - to the risk of suicide, assessed by the presence of suicidal ideation. It also intends to investigate the possible interaction between interpersonal needs and the respective quadratic effects, by controlling the impact of a set of variables which have, many times, a significant correlation with suicidal ideation. In this study participated 80 elderly patients recovering from an acute medical condition. According to the results, thwarted belongingness and perceived burdensomeness are correlated with suicidal ideation. However, when in a multiple regression analysis we considerate simultaneously the effect of both variables, only thwarted belongingness contributes significatively to suicide ideation prediction. No interactions effects or quadratic effects were observed between interpersonal needs variables.

Full textAbstract:
This study investigates the apparent threat assessment priorities of potential risks to safety in the school environment in the United States and whether stakeholders in Florida private schools that serve exceptional students agree with the priority given to specific identified potential threats. Faculty and staff, high school students, and the students’ parents and guardians at four Florida private schools for exceptional students rated their perceptions of the severity and likelihood of occurrence of nine potential threats identified in a review of federal and Florida state school safety laws and national and state government surveys of incident occurrences. Results showed that although violent potential threats such as an armed intruder, students bringing weapons to school, and physical assaults received priority attention in federal and state school safety laws, stakeholders in Florida private schools for exceptional students indicated that threats of a more personal nature—such as bullying, sexual harassment, and cyberbullying—were the most significant risks to the safety of their school environment. All three respondent subgroups, however, reported high ratings of their overall feelings of safety at their schools.

Full textAbstract:
Perceived risk of inherited susceptibility to cancer (ISC) historically has been determined by objective measures, which neither emphasize how people with ISC perceive their risk of cancer, nor address the meaning of being at risk. The few studies of perceived risk of ISC provide sparse data regarding the process of perceived risk. Knowledge of this process is important because perceived risk may affect how people act to reduce their cancer risk. This study tested the investigator-developed perceived risk of ISC (PRISC) model to learn about this process. The PRISC model, a latent variable (LV) model, is based on existing literature and a preliminary phenomenological study of women at high risk for breast cancer. LVs (Awareness, Perceived Risk, Fear, Support, and Action) in the PRISC model cannot be measured directly, rather, the score of the LVs is inferred through measurements of associated indicator variables. The purpose of this cross-sectional study was to: (a) estimate psychometric properties of instruments used to measure PRISC model indicator variables; (b) test the fit of the PRISC model with instrument-generated data; and (c) examine relationships among the LVs. The sample of 200 women had no cancer history and met established criteria for hereditary predisposition to breast cancer. Participants completed 12 self-report instruments. Analysis of instruments included descriptive statistics, estimates of internal consistency, and confirmatory factor analysis. Testing of the PRISC model used structural equation modeling (SEM) techniques. Psychometric analysis indicated eight instruments had acceptable standardized alpha coefficients of at least .70. Items in most scales loaded on one factor. SEM resulted in two models: one fit acceptably with the data but did not support relationships between LVs Awareness and Perceived Risk and Perceived Risk and Support. Respecification of the model (deleting Perceived Risk) resulted in poor fit with the data, but significant correlations between Awareness and Fear, Fear and Action, and Support and Action. Instability of the PRISC model indicated the need for theory-driven respecification and reconsideration of some instruments for future analysis. Although instability precludes generalization of findings, the model suggests that fear and support may positively predict action to reduce cancer risk.

Full textAbstract:
Contingency theory, with regard to risk of homeland security incidents and homeland security preparedness, has received considerable empirical support. In past research, risk has been measured subjectively as agency executives' perceived risk of specific homeland security incidents occurring within their jurisdictions. This study examines actual risk, using the objective risk factors of experience with past natural hazards, social vulnerability, and urbanization. These risk factors, used in combination, have been significantly associated with terrorism-related homeland security incidents in the United States, and are used in risk assessment models of natural hazards. Contrary to expectations, the results of this study indicate that objective risk factors were not associated with either perceived risk or preparedness. Policy implications and directions for future research are discussed.

Full textAbstract:
The literature reviewed on lot-sizing models with random yields is limited to certain random occurrences such as day to day administrative errors, minor machine repairs and random supply due to faulty delivery of parts. In reality however, the manufacturing industry faces other risks that are non random in nature. One example would be yield discrepancies caused by non random triggers such as a change in the production process, product or material. Yield uncertainties of these types are temporary in nature and usually pertain until the system stabilizes. One way of reducing the implications of such events is to have additional batches processed earlier in the production that can absorb the risk associated with the event. In this thesis, this particular approach is referred to as the anticipatory batch insertion to mitigate perceived risk.
This thesis presents an exploratory study to analyze the performance of batch insertion under various scenarios. The scenarios are determined by sensitivity of products, schedule characteristics and magnitude of risks associated with causal triggers such as a process change. The results indicate that the highest return from batch insertion can be expected when there are slightly loose production schedules, high volumes of sensitive products are produced, there are high costs associated with the risks, and the risks can be predicted with some degree of certainty.

This paper examines whether compliance with COVID-19 mitigation measures is motivated by wanting to save lives or save the economy (or both), and which implications this carries to fight the pandemic. National representative samples were collected from 24 countries (N = 25,435). The main predictors were (1) perceived risk to contract coronavirus, (2) perceived risk to suffer economic losses due to coronavirus, and (3) their interaction effect. Individual and country-level variables were added as covariates in multilevel regression models. We examined compliance with various preventive health behaviors and support for strict containment policies. Results show that perceived economic risk consistently predicted mitigation behavior and policy support—and its effects were positive. Perceived health risk had mixed effects. Only two significant interactions between health and economic risk were identified—both positive.New York University Abu Dhabi

Full textAbstract:
This research addressed the question of how information technology (IT) tools influence the perceived risk of consumers in e-commerce transactions in three phases. First, an exposure-driven model of e-commerce transaction perceived risk was developed and tested, providing a theoretical and conceptual basis for this research. Nine salient risk beliefs were modeled as formative dimensions of three risk belief categories based on prior perceived risk research: information misuse risk, performance risk, and functionality inefficiency risk. The model was tested in an online survey of 565 internet users. The results support the proposed construct of e-commerce transaction perceived risk, modeled as formed by the three proposed risk categories, validating the measurement model and finding that the construct was associated as expected with accepted e-commerce constructs in a nomological network.
In the second phase, this model was used to examine the ways in which IT tools influence those beliefs. Participants were asked to observe an example of one risk-reducing IT tool (RRIT) and to indicate their willingness to use the tool for reducing the probability of each risk category and risk dimension. This research confirmed that consumers do perceive RRIT as being useful in reducing the probabilities of risk categories, compared to their willingness to adopt a control IT tool or other RRIT for that purpose.
The final phase of this research investigates the adoption and influence of RRIT. Participants were shown an example RRIT and were asked to compare a store providing the tool to an identical website that did not provide the tool. This research supported hypotheses that perceived improvements in the probability of one or more of the risk dimensions when an RRIT is provided would lead to an intention to adopt the RRIT, and that the intention to adopt the RRIT would be associated with an improvement in attitude toward buying from a web retailer and the subsequent improvement in intention to buy from a web retailer.

Full textAbstract:
The most natural stochastic models for describing the time evolution of the collective risk reserves of an insurance company are jump or point process models. However, there are difficulties in obtaining from such models explicit and tractable expressions for important quantities such as the probability of ruin and these have spawned the development of procedures to approximate point process models. In this thesis, the nature of weak approximations, as put forward by Iglehart (1969) and Furrer, Michna & Weron (1996), is examined closely with a view toward assessing their value. An interpretation of these approximation procedures is given and a method by which the value of weak approximations may be improved is suggested by considering their Levy-Grigelionis-Jacod characteristics.

Full textAbstract:
The purpose of the current analysis is to look at both individual and contextual predictors of perceived risk of victimization. Specifically, the present work builds directly on the contributions of Rountree and Land (1996) and goes beyond their work in several ways. The current work includes additional census tract measures and redefines a key concept index. Drawing upon routine activity theory, social disorganization theory, and social disorder theory, the current analysis includes individual, neighborhood, and census tract level predictors of perceived risk. Data collected on neighborhood characteristics and crime rates in Seattle, Washington in 1990 are used. Using a multi-stage sampling design, 5,302 individuals were surveyed. Multinomial logistic regression is used in this analysis. General support is found for routine activity theory, social disorganization theory, and social disorder theory. Most notable, however, support is found for including census tract level measures. Suggestions for future research are discussed.

ABSTRACT In the field of science and technology, the most frequently used theory to explain or predict whether a new information system will be accepted are “Theory of Reasoned Action”, “Technology Acceptance Model”, and “Theory of Planned Behavior”. Prior research showed that “Theory of Planned Behavior” helps to understand how we can change the behavior of people. The TPB is a theory which predicts deliberate behavior, because behavior can be deliberate and planned. TPB is the successor of the similar Theory of Reasoned Action. The succession was the result of the discovery that behavior appears not to be 100% voluntary and under control which resulted in the addition of perceived behavioral control. According to TPB, human action is guided by three kinds of considerations: 1.Behavioral Beliefs, 2.Normative Beliefs, and Control Beliefs. vi This research combines the “Theory of Planned Behavior” and the “Perceived Risk Theory” to study factors which influences wireless restaurant information system. Data were collected from three major cities: Taipei, Taichung, Tainan in Taiwan and Shanghai. The survey measures for the study were derived from previously published studies. The scales measuring the constructs were adapted from prior research. The actual questionnaires used in the survey are presented in appendix. The research findings show that:

The purpose of this study is to observe whether perceived risk will influence participants’ emotional display, and to compare emotion report written by participants knowing their report would be seen by their opponent with those who didn’t know. Through this contrast, an exaggeration, or gaming emotions in emotional display could be observed. There is a discussion on the differences between participants’ emotional displays from the viewpoint of prospect theory, proposing that people are risk-averse in gain situations and risk-seeking in loss situations. The study is a 2x2 experimental design, with knowing/unknowing (their components will see their emotion report) and high/ low risk as two independent variables, and the changed level of anger/ expectation as two outcome variables. There are two experiments in this study, and both of them were conducted by invented stories in questionnaire. Participants were asked to report their current emotional state and their changed level of emotion. Experiment 1 is designed as gain situation, while experiment 2 as loss situation. Two-way analysis of variance and simple main effect of factors were conducted in the study. Experiment 1 found know/not know have significant impact on anger display, but no significant impact on expectation display. Moreover, participants tend to reduce their display level of anger after knowing their report would be seen. Risks have significant impact on both anger and expectation displays. The impact from interaction of factors on emotion displays is not significant. Experiment 2 found know/ not know have no significant impact on emotion displays, and risks simply have impact on the display level of anger. As experiment 1, there is no significant impact on emotional display from factors’ interaction. In addition, the study found that participants in experiment 1 (gain situation) have lower perceived risk, and they reduced their level of anger after knowing their match will see the report, showing the tendency of risk averse. Although participants in experiment 2 (loss situation) have higher perceived risk than participants in experiment 1, the attempt to avoid anger display is not obvious. This outcome is in accordance with prospect theory. Gain and loss situations did have impact on participants’attitude toward risks, which further influence their decisions in gaming emotions.

Currently, the use of community currencies in Taiwan is promoted in the form of “Time Bank” and “Hours”, also known as the “Time dollar”. With the desire to integrate the degree of involvement and perceived risk respectively as the antecedent of the theory of planned behavior (Ajzen, 1985), this study to explore the relationships between these antecedents and the influence of "attitude"、"subjective norms" and "perceived behavioral control" on the "behavioral intentions" of community currency so as to enhance the the promotion of community currency from the perspectives of community. Data collection have been conducted a field survey from March to September, 2017. The respondents have been selcted according to the members of the county and community building centers under the platform of the national community through the website of the Ministry of Culture. After sampling from the geographical stratification (North District, Central District, Southern District, Eastern District), with 5% ~ 10% as the expected community sampling rate, there were total one to five residnets from each selected community have been adopted questionnaire. Data have been analized by structural equations modling and demostrated that：(1) In the theory of planned behavior, "subjective norms" and "perceived behavioral control" have a high correlation with "behavioral intentions", but the path of "attitudes" toward "behavioral intentions" is not significant, showing that no precise beliefs can be used as a basis for evaluation due to the emerging concepts of community currency. (2)When the degree of involvement is used as a proactive variable in the theory of planned sexual behavior, "attitude", "subjective norms" and "perceptual behavior control" appear to structural equation models to have a higher relevant toward "behavioral intentions", but some of the indicators of absolute and value-added fit have underperformed. (3) When perceptual risk is a pre-project variable in the theory of planned behavior, it is revealed in the structural equation model that "attitude", "subjective norms" and "perceptual behavior control" are negativly related to the "behavioral intentions" of community currencies. However, some of the indicators of absolute and value-added matching have underperformed. (4) From the perspective of involvement degree and perceptual risk integration into the pre-event model of the planned behavior theory, it can be found that only the involvement level shows "attitude", "subjective norms" and "perceptual behavior control" in the structural equation model would have a high correlation with the "behavioral intentions" of community currencies. However, the path of "attitude" to "behavioral intentions" is not significant, but some of the indicators of absolute and value-added matching have underperformed. The results of this study found that the degree of involvement as the positive factors will make the community in promoting the use of community currency. However, the perceptual risk becomes a negative factor to limit the intention toward community currency but not supported in structrucal equation modeling. It is hoped that the results of this study can provide the evidence and reference to promote the use of community currency.

Full textAbstract:
This research aimed to explore the social representation of a ‘risky identity’ with regard to
HIV. 12 students participated in the research and these participants were required to take
photographs regarding their perceptions of a ‘risky identity’. Each participant also took part
in a semi-structured interview that prompted discussion of the photographs and the different
factors perceived to influence the risk of HIV infection. These interviews were audiorecorded
and transcribed. Discourse analysis was used to analyse the data and how the
participants position the ‘other’ as more at risk of HIV infection than the self. The analysis
also revealed that the most common factor perceived to influence the risk of HIV infection is
substance use. Other factors include: gender, race, age, and socio-economic status.
Interestingly, the participants found it easier to attribute risk to behavioural and
environmental factors, whereas they were more reluctant to associate risk with factors such as
race and gender. In fact, when doing so, many of the participants emphasised the impact of
environmental and behavioural factors as a means to justify their perceptions. The risk of
justifying social representations in such a manner is that prejudiced attitudes remain, just in a
seemingly more socially acceptable form. Subsequently, it is recommended that HIV
prevention programs go beyond education to critical discussions about issues of identity and
the social representations and risk perceptions influencing sexual behaviour.

This study integrates Trust 、Perceived Risk and Transaction Cost theory to construct a model, for investigating the impact factors of intention and behavior of consumers on online group-buying. A questionnaire was adopted for data collection, there are 284 members of well-known shopping community 「ihergo」who finished the questionnaires completely, and the structure equation model (SEM) was applied to analyze the data. This study suggests 6 hypotheses, the data indicates support for 5 hypotheses but not for hypothesis H2. This study results indicate that when consumers take part in On-line Goup-Buying collective shopping activities, their Perceived Risk (PR) and Transaction Cost (TC) is affected by trust and have positive influence on both PR and TC. Finally,this study also validates that the intention and behavior of consumers on On-line Goup-Buying can be explained with the perspective of trust and transaction cost. Keywords

This study aims to explore whether the TPB can be expanded and become an integrated research model that is consisted with the trend of green consumption. Taking Y-generation as the target research group, this research investigates the relationships among health concern, food safety, and environmental protection concern towards purchasing organic food, attitude towards organic food, subjective norms, and perceived behavioral control, and purchase intention towards organic food. Second, try to understand the relationships among perceived value, perceived risk, green trust, and purchase intention towards organic food. The results show that there are positive relationships among health concern, food safety, and environmental protection concern towards purchase intention of organic food. And the relationships between attitude, subjective norms, and perceived behavioral control, and purchase intention towards organic food are also positive. Moreover, the relationships among perceived value, green trust, and purchase intention are also positive and green trust plays as a partial mediator. On the contrary, perceived risk is negatively correlated with green trust. Second, subjective norms can positively affect the attitude towards organic food, and then has a partial impact on purchase intention. Finally, the consumers’ green perceived value may influence attitude towards organic food positively and enhance purchase intention of organic food. On the whole, the hypotheses developed in this study are fully supported

Full textAbstract:
At a state university in the Pacific Northwest, the authors surveyed 477 matriculating
college students about their immunization status, knowledge, self-perceived risk, and
health risk behaviors for hepatitis A and B vaccinations. Review of immunization
records revealed that 10% of these students were completely immunized for hepatitis
A and 58.8% were completely immunized for hepatitis B. Although their knowledge
about hepatitis A and B was very good, there were no significant differences in
immunization status or health risk behaviors based on their knowledge or their self-perceived
risk of hepatitis A and B. About 66% of students perceived they had no risk
or low risk for hepatitis A and B and only 5% felt they had a high risk. In spite of the
low self-perceived risk, health risk behaviors for hepatitis A and B were common in
this population of college students. In the past twelve months, 56.2% of these
students reported being sexually active (vaginal, oral, anal sex), including 20.5% who
had two or more sexual partners. Students with multiple sexual partners reported
having unprotected sex at a high frequency: 61.3% vaginal, 81.1% oral-genital, and
13.2% anal. The non-sexual health risk behaviors were also common in this
population: 53.2% had body piercing/tattoos, and 26.5% traveled internationally to
regions with intermediate to high rates of hepatitis A (Africa, SE Asia, Central/South
America). These students who traveled internationally were more likely to be
immunized for hepatitis A, although 70% remained unimmunized. In addition,
students with multiple sexual partners or with a body piercing/tattoo were more likely
to be immunized for hepatitis B. However, about one-third of these students with
multiple sexual partners or body piercing/tattoo have not completed the hepatitis B
series. The theory of planned behavior was applied to determine factors that are
associated with college students' decision to be vaccinated for hepatitis A and B. For
hepatitis A and B vaccinations, important attitude constructs identified were 'vaccine
effectiveness, vaccine adverse effects, anticipation anxiety, inconvenience, and
vaccine expense.' The subjective norm constructs with the greatest influence for
college students were: 'parents, family doctor, and student health services staff'. The
significant perceived behavioral constructs were 'parents reminder, student health
services (SHS) reminder, and SHS hepatitis vaccine clinic.' In conclusion, there is
still a sizable portion of unvaccinated college students who possess health risk
behaviors for hepatitis A and B, such as multiple sexual partners, unprotected sexual
behaviors, body piercing/tattoos, and international travel. With a greater
understanding of college students' attitudes, subjective norms, and perceived
behavioral control college health services could develop more effective strategies to
educate unvaccinated college students about these risks and motivate them to be
immunized.Graduation date: 2003

As to this innovative product-smart wearable devices, Roger's theory-diffusion of innovation is most widely used in predicting and explaining how people feel toward the innovation products. Besides, Technology Acceptance Model from David's research is widely be applied in understanding how people acceptance for the technology information. In addition, added the Bauer's perceived risk as extra research method in order to analysis the risk issue before consumers purchased. In summary, this study will explore the consumers purchasing behavior toward smart wearable device by using the diffusion of innovation theory, technology acceptance model and perceived risk. The regression analysis and structural equation model will be applied in this study. The hypothesis which full support is showed as follows: Perceived usefulness has significant and positive impact on usage attitude; Perceived ease of use has significant positive impact on usage attitudes; Perceived usefulness has significant positive impact on Behavioral Intention; Usage attitude has significant positive impact on behavioral intentions; Comparative advantage has significant positive impact on perceived usefulness. The hypothesis which partially support is showed as follows: Perceived ease of use has significant positive impact on Perceived usefulness; Compatibility has significant positive impact on Perceived usefulness; Observability has significant positive impact on perceived usefulness. The hypothesis which rejected in result showed as follows: Trialability has significant positive impact on the perceived usefulness; Perceived risk has significant negative impact behavioral intentions.

In online shopping environment, e-retailers continuously improve their website quality and offer richer information related to products to attract more consumers; moreover, the rate of purchasing high-tech products in online stores increases year by year. This study combined Unified Theory of Acceptance and Use of Technology (UTAUT) with Innovation Diffusion Theory (IDT), including performance expectancy, effort expectancy, virtual community building and trialability, and adopted two mediators, familiarity and perceived risk, to examine online shopping behavior. In this study, a web-based survey was employed, and the respondents were drawn from Internet users. 344 valid respondents were collected. Structural equation model (SEM) and regression analysis were adopted for data analysis. Based on the results of SEM, performance expectancy and effort expectancy positively affect website familiarity; virtual community building and trialability positively influence product familiarity. However, performance expectancy, effort expectancy, virtual community building, trialability and familiarity all have no significant effects on perceived risk. Moreover, familiarity positively influence purchase intention; perceived risk negatively affects purchase intention. According to the results of regressing, website familiarity and product familiarity have mediation effects, but perceived risk has no mediation effect. In other words, website designs indirectly affect purchase intention through familiarity. In managerial implications, this study suggests managers should provide a complete community to consumers in order to enable them to share information; furthermore, managers should also build the tryout of products on the website, so that consumers can increase familiarity about websites and products, and in turn, promote purchase intention.

The development of Internet technology has led to the popularity of Social Network Sites. In Taiwan, many enterprises have their own fan pages on Facebook. They organize promotion activities through fan pages to make their brands to be well-known. Nowadays, Facebook provides fan page owners the advertising services which seems to be a very effective way to propagate marketing messages to the potential customers, but the effectiveness of advertisement on Facebook is still unclear, because advertisement posts from unfamiliar users or brands may cause users feel uncertain about the information. This study focuses on comparing four different types of fan page recommendation methods to figure out which ones of them will reduce user’s perceived risk and increase use intention toward fan pages the most. We refer to social contagion theory and adopt the three recommender’s social stages based on the “Structural Equivalence Equals Cohesion” model to see the different effects of them. The research approach of experimental design is used in this study, which is complemented by the use of survey and personal interviews. Based on the survey data collected from 60 students, this study has six hypothesis supported. The fan page recommendation from Facebook recommendation system results in the worst performance and the recommendation from peer friend results in the best performance. The results show that fan page owners should put more energy on the promotional activities which make users to spread the page to peer friends because that will be the most effective way to get more fans.

Dissertation presented as the partial requirement for obtaining a Master's degree in Statistics and Information Management, specialization in Risk Analysis and ManagementUnderstanding of the main determinants associated to Internet and Communication Technology acceptance have received attention from international bodies and researchers (Dewan & Chen, 2014; Featherman & Pavlou, 2003; Im, Hong & Kang, 2011; Ming Chi Lee, 2009; Niehaves & Plattfaut, 2014; Shareef, Kumar, Kumar & Dwivedi, 2011; Shin, 2010; Venkatesh & Bala, 2008; Venkatesh, Thong & Xu, 2012a). The reason behind the growing interest in this issue refers to the implications of digital inequalities in social development. Technology access, income, and education seem to be main of many factors that contribute the level of digital inequality. However, providing access or increasing income will still fail to resolve the problem with low level of technology use. There is no guarantee that if more availability is given to the digitally excluded individuals, that they would increase their ICT usage. The individuals’ rational about ICT acceptance or rejection is proportional to the potential risks and opportunities an individual faces at the adoption stage. Currently, understanding the role of users´ perceived risks in relation to attitude, privacy concerns and perceived security while the ICT adoption in Poland is limited. Hence, this work aims to explain the ICT usage behaviour in the specific context of Poland. To test the developed conceptual model, this study uses the data collected in one of Polish medium size cities, the capital city of region Podlasie. The role of attitude, security and privacy issues have as a would‐be predictors of ICT acceptance, is analysed via survey directed to a representative sample of individuals. Based on the theories and previous literature, this study proposes a theoretical model of UTAUT2 theory in conjunction with attitude, privacy, and security model to be used in understanding the ICT adoption process. Theoretical and practical contributions are also outlined. Parties who should be mostly interested in the results of this study are those who provide online services to wide audience and benefit when the audience uses or absorbs the information or services provided online. Therefore, the theoretical and managerial implications of presented results should be in equal interest of: individuals and organisations active online.

Trabalho de Projeto apresentado como requisito parcial para obtenção do grau de Mestre em Estatística e Gestão de Informação, especialização em Gestão do Conhecimento e Inteligência de NegócioThe understanding of the main determinants of Internet banking adoption is important for banks and users. If banks understand users’ concerns, then they will be able to provide better services. In this investigation we developed a conceptual model that combined the unified theory of acceptance and use of technology (UTAUT) with perceived risk in order to explain behaviour intention and usage behaviour of Internet banking. To test the conceptual model we collected data from Portugal (249 valid cases). We found that the model explained 60 percent of intention to use variance and 81 percent of usage variance. Our findings supported some relationships of UTAUT, as performance expectancy, effort expectancy and social influence, and also the role of risk as a stronger predictor of intention. To explain usage behaviour of Internet banking the most important factor was behavioural intention.

Nesta investigação, foi desenvolvido um modelo conceptual que combina a teoria unificada da aceitação e uso de tecnologia (UTAUT) com o risco percebido, de forma a explicar e intenção e o uso do Internet banking. Para testar o modelo concetual, foram recolhidos dados em Portugal (249 casos válidos). Os resultados mostraram que o modelo explicava 60% da intenção e 81 % do uso. Foram suportadas algumas das relações do UTAUT, como a expectativa de desempenho, expectativa de esforço e a influência social, e também o papel do risco como o forte preditor da intenção. Para explicar o uso do Internet banking, o factor mais importante foi a intenção.

This study was proposed based on the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) and three constructs which include financial risk, performance risk and privacy risk to investigate the determinants controlling online shopping intention of the elementary teachers in Tainan City. Data was gathered using convenience sampling from 390 teachers in ten public elementary schools in Taiwan City. A total of 375 out of 390 questionnaires were completed and returned. Descriptive statistics, t-test, one-way ANOVA, Person product-moment correlation and regression analysis were applied for data analyses. The results of the survey are summarized as follows: 1. Social influence, hedonic motivation, price value, habit, and performance risk had significantly positive correlations with behavior intention. However, facilitating conditions had significantly negative correlations with behavior intention. 2. Behavioral intention had significantly positive correlations with behavior of use. However, facilitating conditions and habit had no significant correlations with behavior of use. The results indicated that social influence, hedonic motivation, price value, and performance risk are the main effects of controlling elementary teachers’ online shopping intention.

This study applies the Stimulus-Organism-Response (S-O-R) theory to examine the mechanisms through which customers’ perceived value might influence their online group buying behaviors. Specifically, the mediating roles of emotional states of pleasure and arousal and the moderating roles of perceived risk and herding tendency are explored to show how customers’ perceived value affects their repurchase intention and electronic world-of-mouth (e-WOM) behaviors towards online group buying. Research findings based on a sample collected from Vietnamese online group consumers show that perceived value exerts a positive influence on emotional states of customers. Moreover, emotion of pleasure produces positive effects on repurchase intention and electronic word-of-mouth. The mediating role of emotion of pleasure and the moderating effect of perceived risk are also confirmed while emotion of arousal and herding tendency are found insignificantly. The study contributes to the S-O-R theory by probing into the psychological factors that drives consumers’ cognitive attitude and their effects on online shopping behaviors. Implications and limitations are discussed as well.

Using the literature on Baumrind&rsquo
s theory of Parenting Styles and how perceptions of these are associated to adolescent at-risk behaviour, this study set out to examine whether any parenting style increased or decreased adolescent substance use. The central aim of this study was to examine the association between perceived parenting styles and adolescent substance use. To further this, 239 grade 10 and 11 adolescent participants were drawn from 3 schools in Mitchell&rsquo
s Plain, a suburb in the Western Cape (with permission granted from the Education Department). This particular suburb was chosen due to the high rates of substance use and substance related crime within the area. A quantitative research design was implemented within this study. The participants were required to complete the Drug Use Disorders Identification Test (DUDIT), a questionnaire aimed at measuring drug use, and the Parental Authority Questionnaire (PAQ), aimed at measuring perceived parenting styles and a Biographical Questionnaire to provide additional information. Informed consent was obtained and the confidentiality of the schools and participants were protected. Data analysis was conducted using SPSS, a data analysis programme available at the University of the Western Cape. Results show that substance use reduction was significantly related to a perceived authoritative parenting style. However, no significant relationships could be found between perceived permissive and authoritarian parenting style. Significant difference was found in the results obtained for male and female adolescents, with males generally appearing to use more substances. It can be concluded that perceived authoritative parenting styles have an important role to play in the prevention of adolescent substance abuse

In current digital era, the development of technology and internet has expedited the information transfer to a certain extent. While smart phones are getting more and more prevailing, internet and instant communication become much more accessible to people, and serve as a more efficient channel for people to communicate anytime and anywhere. In light of recent trends, the popularity of smart phones in Taiwan is expected to reach its climax in 2016. The mobile internet, enabling the mobile bank users to access to the bank service anytime and anywhere, not only provides great convenience to customers but also creates more business opportunities for bankers. In sum, to understand the individual intention in using mobile banking is a crutial issue. The purpose of the study is to build up the module with integrated the unified theory of acceptance and use of technology (UTAUT) with perceived risk and initial trust, in order to find out the key factors that could influence mobile bank users. This study tries to understand the mobile users’ perception, perceived risk, and the connection as well as the importance between the mobile bank service and initial trust. We collect data from people who own mobile devices or smart phones. The questionnaire survey was conducted and performed around physical banks in Taipei city, New Taipei city, Taichung city, Kaohsiung city, Tainan city etc. Interview method was taken in the survey. After data collection, the analysis was conducted by software SPSS 18.0, which took descriptive statistics to analyze basic structure such as demographic variables, and used multiple regression analysis to examine the premise of the study. The results show: 1. “initial trust” plays a vital role when it comes to user intention to mobile banking. Under UTAUT module, performance expectance and effort expectance are the strong factors to the intention, while the influence of perceived risks is limited; 2. “user intention” is the key factor to user behavior. 3. The antecedent of establishing “initial trust” should be highly valued. 4. User perception in UTAUT, perceived risks and initial trust cause the direct and indirect effects to the user intention to mobile banking. The findings provide useful information for bankers when they are working on the strategy to increase customers’ motivation in using mobile bank, so as to create more business opportunities.
