Full textAbstract:
It is the aim of this thesis to consider two accounts of 1st-person utterances that are often mistakenly conflated - viz. that involving the 'no-reference' view of "I", and that of the non-assertoric thesis of avowals. The first account says that in a large range of (roughly) 'psychological' uses, 'I' is not a referring expression; the second, that avowals of 1st-personal 'immediate' experience are primarily 'expressive' and not genuine assertions. The two views are expressions of what I term 'Trojanism'. This viewpoint constitutes one side of a 'Homeric Opposition in the Metaphysics of Experience', and has been endorsed by Wittgenstein throughout his writings; it has received recent expression in Professor Anscombe's article 'The First Person'. I explore the ideas of these writers in some depth, and consider to what extent they stand up to criticism by such notable 'Greek' contenders as P.F. Strawson and Gareth Evans. I first give neutral accounts of the key-concepts on which subsequent arguments are based. These are the immunity to error through misidentification (IEM) of certain 1st-person utterances, the guaranteed reference of 'I', avowal, and the Generality Constraint. I consider the close relation of Trojanism to solipsism and behaviourism, and then assess the effectiveness of two arguments for that viewpoint - Anscombe's Tank Argument and the argument from IEM. Though each is appealing, neither is decisive; to assess Trojanism properly we need to look at the non-assertoric thesis of avowals, which alone affords the prospect of a resolution of the really intractable problems of the self generated by Cartesianism. In the course of the latter assessment I consider the different varieties of avowal, broadening the discussion beyond the over-used example 'I am in pain'. I explore Wittgenstein's notion of 'expression', and discuss how this notion may help to explain the authority a subject possesses on his mental states as expressed in avowals. My conclusion is that an expressive account of avowals can provide a satisfactory counter to the Cartesian account of authority without our needing recourse to a non-assertoric or even to a non- cognitive thesis. Discussion of self-consciousness is implicit in discussion of the Homeric Opposition, but there is in addition a short chapter on the concept itself.

Full textAbstract:
Prior research suggests that rejection sensitive individuals may find it easier to express their true selves in an online environment. The purpose of the present study was to further examine the influence of true self, which is who a person believes he or she truly is, on the relationship between rejection sensitivity and online dating site usage. Additionally, the present study investigated the role of self-disclosure in online dating site usage. Five-hundred sixty one participants completed an online survey. Consistent with prior research, results indicated that rejection sensitivity and true self predicted online dating site usage. Further, true self partially mediated the relationship between rejection sensitivity and online dating site usage. Self-disclosure in online environments, however, did not influence the relationship between rejection sensitivity and online dating site use. In addition, for those who engaged in online dating, rejection sensitivity was not related to self-disclosure in online dating profiles or in communicating with individuals met through online dating sites. True self, though, was related to both self-disclosure in online dating profiles and in communication with those met through online dating sites. These findings suggest that rejection sensitive individuals are more likely to engage in online dating because it may facilitate representation of their “true” selves. Furthermore, rejection sensitivity may not facilitate individuals’ self-disclosure in online environments, whereas the desire to share one’s “true” self may facilitate self-disclosure in online environments.

Full textAbstract:
The focal point of this thesis is on whether and how digital practices can challenge and reintroduce values and concepts related to self-awareness and spatial sensitivity. It uses prosuming practices of food and social media as a research and learning tool. Prosumption is a compound word formed by joining the words production and consumption and, in brief, it means producing for one’s own consumption. This study is conducted in the area of digital media and architecture. The main architectural interest lies in the way that place (and notions related to the private and public spheres) is perceived by its users and how this experience can be affected by prosuming social media platforms every day. In particular, this study explores if and how digital media, especially the prosuming of social media content, alters preestablished issues related to spatial sensitivity. A thorough critical examination of the prevailing views on these topics, as well as their evolution in time, is described. The present status of the matters studied is approached by a literature review and an empirical study using mainly phenomenological methods of approach. Food prosuming is explored first and the conclusions reached, related to self awareness and spatial sensitivity, are then further tested and attempts are then made to apply these to social media content prosuming. The research methods used involved in-depth interviews with 35 participants over a period of two years. Individuals who covered a spectrum of different ages, social groups and professional categories were selected for interview. Data relating to the documentation of prosuming practices of the participants, questionnaires, and personal reflections through blogging and social media practices were recorded. Furthermore, one intervention of public prosuming activity was also investigated. As it was found in food prosumerism, there is a significant difference if practiced occasionally and when practiced in the frame of habitual everydayness. This differentiation can be related to and affect issues such as privacy and the personal and social spheres. It was also found that while casual prosuming in the digital domain of social media involves aspects and values of the public domain, everydayness transforms these digital prosuming practices into familiar practices as they are habituated in the private domain. Schematically, this can be represented as: Public → Casual → Private. Everyday digital prosumerism cultivates and incorporates issues of the private domain, whereas by definition it should incorporate issues of the social domain. This is what in this thesis is referred to as issues of the public-private domain. This remark, though, affects the essence of spatial sensitivity, the understanding of the private and the social sphere and the values and tendencies involved. Our findings suggest that, in most cases of food prosuming, when sharing, the host aims to instil a specific mood for the event, to be responsible for the setting, the ambience, the atmosphere of the sharing experience with the guests and the facilitation of sharing. In the digital domain, the mood and ambience of the sharing setting might follow the same pattern as is facilitated by the host, but at the same time the process of sharing sets the mood in an accelerated process; it is co-created, continued or totally altered by the public private sphere. Prosumerism as explored so far is correlated positively to issues of selfactualization and personal wellbeing (Xie, Troye and Bagozzi, 2008). Do digital prosuming practices share the same qualities? Personal atmospheres today, or what we call in this thesis aetherspheres, incorporate values and issues cultivated and fed by the fused atmosphere of the physical and the digital domain, forming a new ethos of prosumerism and crafting new norms.

Full textAbstract:
Although the psychological effects of appearance schemas have been studied in the general population, we know little about the relation of these schemas to appearance-based rejection sensitivity. This study examined the relations among predictive variables of appearance-invested self-schemas (self-evaluative salience [SES] and motivational salience [MS]), appearance-based rejection sensitivity, and depressive affect. Self-discrepancy theory was used to theorize that when individuals experience discrepancies with self, conflict arises in self-schemas, and that this conflict relates to an increase in depressive affect and appearance-based rejection sensitivity. The sample consisted of 131 adult female college students participating in a continuing education program. Multiple regression was used to evaluate the relation between appearance-invested self-schema and depressive affect. A second multiple regression equation was conducted to evaluate the relation between appearance-invested self-schema and appearance-based rejection sensitivity. Participants with higher SES scores had significantly higher depressive affect scores and appearance-based rejection sensitivity scores. Participants with higher MS scores had significantly lower depressive affect and appearance-based rejection sensitivity scores. High SES significantly predicted more depression and sensitivity to rejection based on appearance, and high MS appeared to be a protective factor against depression and appearance based rejection. The results of the study promote positive social change by helping professionals improve treatments for individuals suffering from negative appearance-invested self-schemas, rejection sensitivity, and depression.

Full textAbstract:
Background/aims. Self-compassion is an approach of kindness towards the self; encompassing self-kindness, common humanity and mindfulness (Neff, 2003b). It is thought to enable awareness that suffering is common within human experience, encouraging compassion for others. Parental sensitivity and attributions are considered to influence parent-child relationships and have been negatively associated with depression. This study aimed to explore associations between parent self-compassion, attributions of child behaviour and sensitive responding in recurrently depressed parents. Methods/participants. This was a correlational design using baseline data from a feasibility randomised controlled trial of Mindfulness-Based Cognitive Therapy. The 38 participants had experienced recurrent major depressive episodes, were in remission and had at least one child between two and six years old. Self-compassion was measured by the Self-Compassion Scale (SCS; Neff, 2003b). Parent attributions of child behaviour were assessed by semi-structured interviews and rated using the Attributions Measure (S. Scott & M. Dadds, personal communication, 2009). Sensitivity was assessed using a parent-child observation task and rated by the Coding of Attachment-Related Parenting (Matias, Scott & O’Connor, 2006). Results. Findings show significant correlations between higher SCS total scores and external attributions of positive or negative valence. The SCS subscale self-judgement was significantly negatively correlated with sensitivity. Conclusion. In conclusion, higher self-compassion was positively associated with external attributions of child behaviour in either situation. Parents with higher levels of self-compassion also showed positive associations with sensitivity. These associations support current theories suggesting self-compassion could be positively associated with parenting. Areas for future research and clinical implications are considered.

Full textAbstract:
PsychologyPh.D.
Nonsuicidal self-injury (NSSI), the deliberate self-destruction of one’s own body tissue engaged in without associated suicidal intent, is a prevalent behavior among adolescents and young adults. The current study examined whether one aspect of cognitive control, inhibitory control in response to negative emotional stimuli, is associated with repetitive engagement in NSSI. It further sought to examine whether sleep deficiency/irregularity, stress, and reward sensitivity moderate this relationship. A multi-method approach (self-report, behavioral measures, actigraphy) was employed to sensitively probe these relationships among 114 late adolescents with and without a history of repetitive NSSI. Findings suggested no relationship between inhibitory control in response to negative emotional stimuli and NSSI, as measured by a behavioral measure, but a significant positive relationship as measured by self-report. Stress and sleep irregularity, but not sleep deficiency or reward sensitivity, were associated with NSSI group status. Interaction analyses suggested that sleep irregularity and stress moderated the relationship between inhibitory control in response to negative emotional stimuli and NSSI. Results are discussed in terms of conceptual and clinical implications. Findings highlight the necessity of examining the temporal dynamics between the study’s constructs and NSSI by employing an ecologically valid approach.

Full textAbstract:
A sensitive parent-child relationship is essential in ensuring the healthy mental and physical development of an individual. Parental sensitivity can be affected by parent characteristics, such parental competence and resources as well as child characteristics, such as negative reactivity. The combination of how these parent and infant factors predict parental sensitivity has not been examined with both mothers and fathers. The current study involved 30, 4-month old infants and their mothers and fathers. Parents completed questionnaires measuring infant temperament and parental competence. They also participated in a demographic interview to measure family resources, as well as a dyadic parent-infant face-to-face play task to measure parental sensitivity. Results involving mothers indicated a moderating effect of infant temperament (e.g., negative reactivity) on the associations between parental competence (e.g., self-efficacy) and parental sensitivity. Whereas for fathers, results indicated significant main effects of infant temperament (e.g., orienting) and parental competence (e.g., self-efficacy) on parental sensitivity. The current study gives evidence and support that it is a combination of both parent characteristics and infant characteristics that affects parental sensitivity. However, this combination of characteristics is different for mothers and fathers, indicating that different factors play a part in parenting behaviors for mothers and fathers.

Full textAbstract:
Objectives: We sought to examine the gender differences between C - reactive protein (CRP) and muscle strengthening activity (MSA) in U.S. adults (≥20 years of age)
Background: Elevated levels of CRP have been shown to be associated with an increase in risk of cardiovascular disease (CVD). Studies analyzing the relationship between physical activity (PA) and CRP by gender have produced mixed results.
Methods: The sample (n=9,135) included participants in the 1999-2004 National Health and Nutrition Examination Survey (NHANES). Three categories of reported MSA participation were created: no MSA (referent group), some MSA (≥1 to/wk), and meeting the 2008 Department of Health and Human Services (DHHS) recommendation (>2 d/wk). The dependent variable was elevated CRP (>3 to 10 mg/L).
Results: Gender stratified analysis revealed significantly lower odds of having elevated CRP for women reporting some MSA (OR 0.61; 95% CI 0.45-0.83, P=0.0023), or volumes of MSA meeting the DHHS recommendation (OR 0.66; 95% CI 0.54-0.82, P=0.0004). Significantly lower odds of men having elevated CRP was observed in those reporting MSA volumes meeting the recommendation (OR 0.73; 95% CI 0.61-0.88, P=0.0011). Following adjustment for waist circumference (WC) these odds remained significant in men but not women.
Conclusions: Women reporting any MSA were found to have lower odds of having elevated CRP when compared to those reporting no MSA prior to adjustment for WC. Significantly lower odds in men were only observed in those meeting the recommendation. These results suggest that WC may mediate the associations between MSA and CRP and this relationship may be stronger in women.

Full textAbstract:
Biosensors have a multitude of important applications in basic research, environmental monitoring, biodefense, and medicine. This research aims to show that Ionic Self-Assembled Multilayers (ISAMs) adsorbed on Long Period Gratings (LPGs) can serve as a highly sensitive, robust, inexpensive optical-based biosensor platform. The ISAM technique is a layer-by-layer deposition method that builds nanometer-thick films based on the principle of Coulomb attraction between oppositely charged polyelectrolyte solutions while LPGs cause strong attenuation bands that enable an optical fiber to be extremely sensitive to changes in the surrounding environment. LPGs have been shown to be highly sensitive to the adsorption of nanoscale self-assembled films on the optical fiber cladding surface. In this work, we utilize Turnaround Point (TAP) LPGs, which possess even greater sensitivity than standard LPGs. This thesis focuses on evaluation of approaches to increasing the sensitivity of the sensor platfom, implementation of a biosensor for detection of several biomolecules, and preliminary evaluation of the potential for pH sensing.
For a thin-film coated TAP LPG, we have demonstrated that shifts in the transmitted light intensity at the resonant wavelength of the LPG can result from the variation in film thickness and/or refractive index. We have observed decreases in intensity as large a 7 dB for one bilayer of ISAM film (~1 nm), which corresponds to an 80% decrease in the transmitted light intensity at the resonant wavelength. We have also shown that the sensitivity of the TAP LPG sensor can be increased by implementing nm-thick ISAM films that have a refractive index greater than silica. Furthermore, it is shown that incorporation of silica nanoparticles into the ISAM films significantly increases sensitivity through increased surface area and thickness.
The biotin-streptavidin system was used as a model for implementaion and optimization of the ISAM-coated TAP LPG biosensor platform. Through evaluation of various biotin derivatives to maximize the amount functionalized onto the ISAM film, optimization of the ISAM film properties, and use of LPGs designed for higher sensitivity, the minimum detectable concentration of streptavidin was decreased from 0.0125 mg/ml to 12.0 ng/ml. The biosensor platform was then tested on prostate specific antigen (PSA), which is used as a clinical marker for early diagnosis of potential prostate cancer. Using a direct crosslinking approach of the monoclonal antibody to PSA into the ISAM film, a sensitivity level of 11.64 ng/ml PSA was obtained through combined optimization of the ISAM film and antibody surface coverage. Finally, the potential of ISAM TAP LPGs as pH sensors was examined based on the pH dependent swelling of ISAM films.Ph. D.

Full textAbstract:
Most people will experience rejection in the job selection process. Rejection from job opportunities is often issued via a letter from a hiring manager. These letters elicit reactions from applicants who may, in turn, have less favorable self perceptions and less favorable perceptions of the organization from which the applicant was rejected. Numerous research articles have been published that deal with delivering notification of selection and/or rejection to applicants in the job selection process. However, relatively few use a realistic laboratory design to obtain results. This study examined the effects of sensitivity and information in notifications of rejection when applicants are rejected in the job selection process. A more realistic laboratory design was used to increase the psychological fidelity of the job selection situation. One hundred forty undergraduate students participated in this study. Participants were told to imagine that they were graduate school applicants. Then, the participants completed a fake graduate school admissions test and received notification of rejection from a fake graduate school. Participants were assigned to conditions (letters varying in sensitivity and information type) randomly and the participants completed a post-notification of rejection survey that captured their self and organizational perceptions. Additionally, moderating variables were explored.M.S.

Full textAbstract:
People with high norm-based rejection sensitivity have heightened anticipatory anxiety and expectation of rejection if they do not follow norms. Under threats of rejection (e.g., when personal preferences collide with group norms), they are more intended to conform to group norms to avoid social rejection (Poon et al., 2010). Thus, they are more susceptible to peer pressure for risk-taking behaviors and have less autonomy to make decision. Research also indicates that they derive their self-worth from external sources such as success in academic and work settings (Yip et al., 2009). Thus, they experience elevated anxiety for uncertain outcome and decreased self-esteem following failure. The purpose of the present research is to examine strategies that can alleviate the negative impacts of norm-based rejection sensitivity.
Using a priming procedure, Study 1 experimentally examined the effects of promoting multiple routes to social acceptance. Participants of experimental group read stories of public figures who gained social acceptance through multiple routes such as ego strength and morals. Those stories reminded them that even if they did not follow group norms, they could still gain social acceptance through different virtues. After that, they indicated their reactions in some hypothetical scenarios involving threats of rejection and failure. As expected, those who read stories of public figures (vs. tourist spots) were less intended to conform under group pressure, more autonomous in deciding whether or not to conform, less anxious about the repercussions of non-conformity, and more inclined to expect social acceptance despite non-conformity.
Since participants who read stories of public figures may still base their self-worth on social acceptance, Study 2 aimed to remind them that others’ approval was not required for one’s self-acceptance. Using the same priming procedure as Study 1, participants of experimental group read life stories of ordinary people whose self-worth was not contingent on others’ approval. Those stories could remind them that others’ approval was not required for one’s self-acceptance. Results showed that participants of experimental group were less intended to conform, more autonomous, and less anxious about the repercussions of non-conformity. Furthermore, they reported less decline in self-esteem following social rejection.
In Study 2, those who learnt not to base their self-worth on others’ approval might be still susceptible to greater negative affect following failure in academic and work settings. Therefore, Study 3 went one step further to promote unconditional self-acceptance. Using the same experimental paradigm, participants of experimental group read a passage highlighting the idea that everyone is intrinsically valuable regardless of whether one is self-efficacious and popular. As expected, in additional to the aforementioned psychological benefits, participants being primed with unconditional self-acceptance were less anxious about failure, less likely to blame themselves for failure, and less likely to experience loss of self-worth following failure.
The three experiments shed lights on the psychological mechanisms through which multiple routes to social acceptance and self-acceptance temporarily alleviate the negative impacts of norm-based rejection sensitivity. Further studies can examine whether continuous acceptance-based and mindfulness-based interventions have long-term benefits for people with high norm-based rejection sensitivity.published_or_final_version

Full textAbstract:
The present study investigated the interrelationships between various constructs drawn from the attachment, temperament, and neuropsychology frameworks in the context of self-regulation development and maintenance. In particular, the study sought to determine whether attachment security in early childhood was a predictor of self-regulation and social competence in adolescence, and to elucidate the roles of inhibitory control (IC), maternal sensitivity, and self-control in this relationship. Structural equation modeling was used to create an integrated theoretical developmental model of self-regulation. Attachment Security at 24 months was found to be a significant predictor of Social Skills at age 15 years. In addition, IC at 54 months, Maternal Sensitivity during third grade, and Self-Control during 4 th grade, were found to be subsequent partial mediators of this relationship. Overall, results of the study suggest that foundational self-regulatory capacities such as inhibitory control evolve from patterns of sensitive caregiver-child interactions in early attachment relationships. Furthermore, these capacities appear to be maintained in part through sensitive caregiving throughout childhood and into mid-adolescence. Additional implications of these results for integrating concepts of divergent theoretical domains are also discussed.

Moore-Jervis, Sharnee. "Improving Nursing Knowledge of African American Heart Failure Self-Care Management." ScholarWorks, 2019. https://scholarworks.waldenu.edu/dissertations/7703.
Full textAbstract:
Heart failure is a complex chronic disease affecting 6.6 million people in the United States, with an annual cost of $39.2 billion per year. African Americans are at an especially high risk for poor outcomes and readmissions from heart failure complications, as they are 2.5 times more likely to develop heart failure than other ethnic groups. This disease requires a high level of patient self-care management, and evidence suggests that African Americans do not always receive culturally sensitive education, which can lead to suboptimal self-care practices. The practice-focused question for this educational program asked whether nurses of African American patients with heart failure could use a culturally sensitive health education toolkit to improve patients’ knowledge of self-care management. The purpose of this doctoral project was to determine if a culturally sensitive toolkit could increase nursing knowledge. The population focus was nurses caring for African American heart failure patients with frequent readmissions from a high-risk heart failure clinic in New Jersey. The use of Hofstede’s cultural dimensions and an exhaustive literature review guided this doctoral project. The tool used to assess participants’ pre- and post-knowledge was the cultural awareness and sensitivity tool. There were 11 participants comprised of nurses, nurse case managers, and advanced practice nurses; they exhibited a 1.92% improvement in knowledge after the education session. This outcome shows that this educational program was effective and has the potential to contribute to social change by educating nurses on providing effective, culturally sensitive self-care education to African American heart failure patients to increase their adherence to self-care practices.

Full textAbstract:
This study considers the determination of the ex ante pay-performance relationship. A single-period partial equilibrium model is used to show that the executive income can be expressed as a function of the firm's return expressed in dollar terms. The executive income is jointly determined by the opening firm size and current return, which function as a managerial talent proxy and self-selection mechanism respectively. Comparing to Jensen and Murphy (1990) wealth-based Pay-Performance Sensitivity (PPS), this research presents an income-based PPS. The alternative PPS not only overcomes a misleading misspecification in Jensen and Murphy (1990), but also corrects Rosen's (1992) argument for only including return in the pay performance relationship. This research finds empirically that both the opening firm size and stock return play a significant role in determining executive income. This study provides supplementary evidence to Murphy's (1986) Learning Model.

Thesis, Högskolan i Halmstad, Akademin för ekonomi, teknik och naturvetenskap, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:hh:diva-36955.
Full textAbstract:
Background: Low back pain (LBP) is the leading cause of disability and is often accompanied with a back-related leg pain (around 60%), where those with radiating pain show worse overall clinical outcomes. Previous studies comparing these two groups have involved individuals with chronic LBP. It is not known if subjects who currently have LBP differ in pain sensitivity from those who have currently LBP accompanied with pain radiation to lower limbs. Aim: The aim of this study was to investigate whether there are differences in self-reported health and pain sensitivity between individuals currently having LBP with and without pain radiation to lower limbs. Method: Individuals with LBP (n=100) aged 40 to 70 years participated in this study. According the first question of STarT Back Pain Screening Tool about the pain radiation to leg(s), individuals were divided into two groups: radiation group (RG, n=36) and no radiation group (noRG, n=64). To gain the information about self-reported health, following questionnaires were used: Roland-Morris Disability Questionnaire, Fear-Avoidance Beliefs Questionnaire and Hospital Anxiety and Depression Scale. Pressure pain thresholds (PPTs) were measured with algometer (6 sites and 4 points of ’lower body’: gluteal and knee points). Mann-Whitney U-test was used to calculate differences on group and gender level. A logistic regression analyses was calculated (crude model), where belong to RG or not was the dependent variable and all self-reported data and PPTs were independent variables, all data were controlled for gender and age. Results: The RG reported worse disability (p=0.017), higher fear-avoidance beliefs (FAB) about physical activity (p=0.003), worse score in anxiety (p=0.002) and depression (p=0.001), and increased pain sensitivity (p=0.043) in 6 sites PPTs compared to the noRG. Higher score of disability, FAB (physical activity and work), anxiety and depression were associated with an increased risk of belonging to the RG (OR 1.05-1.50, 95% CI 1.01-1.94), controlled for gender and age. Conclusion: Individuals with LBP and pain radiation to lower limbs showed worse self-reported disability and fear-avoidance beliefs about physical activity than those with LBP only. Further, those with pain radiation were more sensitive to pain in general. Worse scores of all studied self-reported data were associated with an increased risk of belonging to the groups with pain radiation. To study gender differences larger sample sizes are needed. Individuals with LBP and pain radiation to lower limbs showed worse outcomes and therefore should receive a different treatment approach than those who have only LBP.

Full textAbstract:
Suicide is a significant public health issue in the US. Despite national and international prioritization since 1996, little definitive progress has been made in terms of identification and intervention in cases of elevated suicide risk. Forty percent of those who died by suicide attended an emergency department within a year of death. Therefore, universal suicide risk screening in emergency departments could prove a vital component to a national suicide prevention strategy. The present study empirically evaluated the universal suicide risk screening program recently implemented at Parkland Health and Hospital System. The sample consisted of patients over 18 years of age (N=333,855; Mage=42.7, 32% male) screened as part of routine clinical care from May 4th, 2015, through November 3rd, 2015. The Parkland Algorithm for Suicide Screening (PASS) is part of a clinical decision support system for responses to Columbia - Suicide Severity Rating Scale Clinical Practice Screener (C-SSRS) items, leading to an automated clinical response via three suicide risk stratification levels: no action for no risk identified, psychiatric social worker assessment for moderate risk identified, and psychiatrist/psychologist interview for high risk identified. The present study used receiver operating characteristic (ROC) curve analysis, which found the PASS predicted disposition (z=30.46, p<.001, AUC=.78, CI95=.77, .81). This study also evaluated the cutpoints separating suicide risk stratification and levels of clinical response. The results supported the first cutpoint and highlighted a need for additional data to address the second cutpoint. The results of the present study suggest that the universal suicide risk screening program at Parkland Health and Hospital System is an important step toward addressing suicide prevalence in the US.

Full textAbstract:
Based on existing theories of personality and socio-emotional functioning (e.g. Clark, 2005; Lynch, Hempel & Clark, in press) a new model is proposed and tested. The model hypothesises that (i) temperament (reward and threat sensitivity) and childhood invalidation predict problems with interpersonal functioning, (ii) this effect is mediated by self-regulatory capacity; where self-regulatory capacity comprises self-control (ranging from emotional over-control to emotional under-control) and flexible control and (iii) self-regulatory capacity itself has a quadratic relationship with interpersonal functioning. A UK community sample (n= 512) completed a self-report survey, measuring each of the aforementioned latent variables. Structural equation modelling (SEM) was used to determine the goodness-of-fit of this and variations of this model. SEM identified that a non-mediation model provided the best fit (χ²=49.403, p< 0.001; CFI=0.98; RMSEA=0.056). Good-fit was obtained for a model including flexible control as a partial mediator (χ²=269.06, p< 0.001; CFI=0.956; RMSEA=0.081) and adequate-fit for a model including over-control as a partial mediator (χ²= 91.744, p < 0.001, CFI=0.932; RMSEA= 0.096). Correlation analyses suggested that over-control and under-control correlated positively with interpersonal problems. Results from SEM provided promising initial evidence for the mediating role of self-regulatory capacity, particularly for the flexible control component. Correlation analyses provided support for the non-linear relationship between self-regulatory capacity and interpersonal functioning, whereby extreme over-control or extreme under-control is associated with interpersonal problems. Findings have implications for identifying mechanisms of change for therapeutic approaches to emotion dysregulation and for understanding the over-controlled population, which has previously been overlooked.

Mingo, Chivon A. "Identifying and Addressing Health Disparities in Black Older Adults with Osteoarthritis." Scholar Commons, 2010. http://scholarcommons.usf.edu/etd/3540.
Full textAbstract:
Osteoarthritis (OA), the most common form of arthritis in older adults, often results in pain, disability and poor psychological well-being. Compared to White adults, Black adults consistently report more pain, more activity limitations, and have different perceptions about OA. Racial disparities also exist in treatments, and prevalence of arthritis. It is imperative to have effective interventions and treatment options for older Blacks. Yet, few arthritis interventions have included Black participants in their samples, and nearly all of those have failed to report separate analyses indicating the effectiveness for Black adults, thus leaving a gap in the literature. The purpose of this study is to begin to identify factors needed to design arthritis interventions that will reduce barriers and increase appeal to Blacks.
The present dissertation consists of one study with two related parts. The first part consists of a needs assessment that examined intervention preferences, barriers to healthcare, knowledge about interventions and care, utilization, and health beliefs among Black and White adults with self-reported physician-diagnosed OA. The second part evaluated materials used in an existing arthritis intervention for acceptability. The study was based on the Arthritis Self Management Program (ASMP). Frequencies were examined to determine needs related to arthritis healthcare of Blacks and Whites recruited from the community. Independent samples t-tests and Pearson’s Chi-square analyses were examined to determine group differences between Blacks and Whites.
Blacks were more likely to report cost, lack of trust, fear of being the only person of their race, lack of recommendation from their doctor, and lack of recommendation of a family or friends as barriers to participating in arthritis interventions. In addition, Blacks were more likely to prefer the intervention content, structure and delivery, and arthritis resources presented in the needs assessment in comparison to Whites. As for the evaluation of the intervention materials, Blacks and Whites were similar on most sections.
Based on our findings we suggest that practical adaptations (e.g., cost) be made to existing arthritis interventions to increase cultural sensitivity. Such adaptations have the potential to minimize barriers and offer a program that would be appealing to Blacks with OA.

Genbäck, Minna. "Uncertainty intervals and sensitivity analysis for missing data." Doctoral thesis, Umeå universitet, Statistik, 2016. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-127121.
Full textAbstract:
In this thesis we develop methods for dealing with missing data in a univariate response variable when estimating regression parameters. Missing outcome data is a problem in a number of applications, one of which is follow-up studies. In follow-up studies data is collected at two (or more) occasions, and it is common that only some of the initial participants return at the second occasion. This is the case in Paper II, where we investigate predictors of decline in self reported health in older populations in Sweden, the Netherlands and Italy. In that study, around 50% of the study participants drop out. It is common that researchers rely on the assumption that the missingness is independent of the outcome given some observed covariates. This assumption is called data missing at random (MAR) or ignorable missingness mechanism. However, MAR cannot be tested from the data, and if it does not hold, the estimators based on this assumption are biased. In the study of Paper II, we suspect that some of the individuals drop out due to bad health. If this is the case the data is not MAR. One alternative to MAR, which we pursue, is to incorporate the uncertainty due to missing data into interval estimates instead of point estimates and uncertainty intervals instead of confidence intervals. An uncertainty interval is the analog of a confidence interval but wider due to a relaxation of assumptions on the missing data. These intervals can be used to visualize the consequences deviations from MAR have on the conclusions of the study. That is, they can be used to perform a sensitivity analysis of MAR. The thesis covers different types of linear regression. In Paper I and III we have a continuous outcome, in Paper II a binary outcome, and in Paper IV we allow for mixed effects with a continuous outcome. In Paper III we estimate the effect of a treatment, which can be seen as an example of missing outcome data.

Full textAbstract:
This repeated-measures study evaluated the relative sensitivity to change of the Child Behavior Checklist/6-18 (CBCL/6-18), the Behavior Assessment System for Children-2 (BASC-2), and the Youth Outcome Questionnaire-2.01 (Y-OQ-2.01). Participants were recruited from Valley Mental Health, a community outpatient clinic in Salt Lake City, UT. There were 178 participants for 136 cases, with 134 adults and 44 adolescents. Participants provided two through five data points for a total of 548 data points. Hierarchical Linear Modeling (HLM) was conducted for three major comparisons: adult informants, adult and adolescent dyads, and adolescents. Results indicated the Y-OQ-2.01 was the most change sensitive, while the BASC-2 and CBCL/6-18 were not statistically different from each other. Results also showed that the parent-report measures were more change-sensitive than the self-report measures completed by adolescent informants. Sensitivity to change was also evaluated through the reliable change index (RCI) and the use of cut-off scores. In comparisons using the RCI, the Y-OQ-2.01 identified the most cases for reliable change. The Y-OQ-2.01 also had the greatest corroboration of its findings with the other two measures. In comparisons using cut-off scores, results are offered for three variations, as different standards were used to establish cut-off scores for the three measures. The third variation, for which cut-off scores for all three measures were adjusted to one standard deviation above the mean, is suggested to be the most appropriate when comparing measures. Those results indicated there was no statistical difference in how the measures performed relative to each other. Thus, based on the HLM and RCI results of this study, it is recommended that clinicians select the Y-OQ-2.01 for outcome use and tracking changes in child and adolescent symptoms and behaviors.

Full textAbstract:
Tjugo procent av alla människor är högkänsliga (HSP = Highly Sensitive Person), vilket innebär att de är födda med ett känsligt nervsystem. Många HSP upplever negativa konsekvenser i sin vardag som påverkar livskvaliteten. Eftersom gruppen HSP är så stor och kopplingen HSP, livskvalitet och självmedkänsla inte specifikt har undersökts, var det relevant att göra den här enkätundersökningen. De undersökta frågeställningar är: Finns det inom gruppen HSP angående variablerna: Livskvalitet, Självmedkänsla, Högkänslighet, BIS, BAS, Extraversion och Neuroticism (a) signifikanta samband mellan samtliga variablerna? (b) Till vilken grad förklarar variablerna Livskvalitet och Högkänslighet? (c) Finns det könsskillnader angående samtliga variablerna? (d) Finns det ett positivt samband mellan Högkänslighet och Ålder? De 111 deltagare var medlemmar i Sveriges Förening för Högkänsliga och samtliga var enligt självskattning HSP, som bekräftades av insamlade data. Deltagargruppen bestod av 93 kvinnor (84%) och 18 män (16%) och genomsnittsålder var 50 år, där lägsta åldern var 35 år och högsta 70. Samtliga frågeställningar har besvarats genom analysmetoderna: Pearsons korrelationsanalys, Standard Multipel Linjär Regression och T-test. Det viktigaste resultatet var att kopplingen mellan HSP och självmedkänsla bidrog med ny kunskap, där slutsatsen blev att utövandet av självmedkänsla kan bidra till att aktivt öka graden av livskvalitet för HSP. Det starkaste sambandet i studien förelåg mellan BIS och neuroticism, vilket betyder att vid en ökning av BIS, ökar graden av negativ affekt och vice versa; resultatet låg i linje med tidigare forskning. Två oväntade resultat var att (a) drivkraften (BASDrive) predicerade högkänslighet mest till skillnad från litteraturen som pekar åt BIS och neuroticism som skulle ha starkast koppling och (b) att graden av högkänslighet sjönk vid ökad ålder; vilket talar emot tidigare forskning. Uppsatsen är en relevant informationskälla för HSP och alla andra som interagerar med HSP.Twenty percent of all people are highly sensitive (HSP = Highly Sensitive Person) which means that they are born with a sensitive nervous system. Many HSP's are experiencing negative consequences in their everyday lives that affect their quality of life. As the group HSP is large and the correlation between HSP, quality of life and self-compassion is not specifically is investigated, the present study was relevant. The examined questions are: Is there within the group of HSP regarding Quality of Life, Self-compassion, High sensitivity, BIS, BAS, Extraversion and Neuroticism (a) significant correlations between the variables? (b) To what extend do the variables explain Quality of Life and High Sensitivity? (c) Are there gender differences regarding the variables? (d) Is there a positive correlation between High Sensitivity and Age? The 111 participants were members of the Sveriges Förening för Högkänsliga and all were HSP according to self-assessment, which also was confirmed by the data collected. The group of participants consisted of 93 women (84%) and 18 men (16%) and the average age was 50, where the lowest age was 35 years and the highest 70. All questions were answered by these analytical methods: Pearson's correlation analysis, Standard Multiple Linear Regression and T-test. The main outcome was that the link between HSP and self-compassion contributed to new knowledge, which concluded that the practice of Self-compassion can help to actively increase the level of quality of life for HSP's. The strongest correlation in the study was between BIS and neuroticism, which means that at an increase of BIS, the degree of negative affect also increased and vice versa; the result was in line with previous research. Two unexpected results were that (a) the driving force (BASDrive) predicted high sensitivity most, unlike the literature suggesting that BIS and neuroticism would have the strongest connection and (b) the degree of high sensitivity decreased with increase in age; which contradicts earlier research. The essay is a relevant source of information for the HSP and all others who are interacting with HSP.

Full textAbstract:
In the United States, asthma remains a major cause of frequent urgent care visits, hospitalizations, and preventable deaths among children. Nationwide, the chronic disease continues to fall disproportionately on minorities, mostly residing in urban localities. When a child is diagnosed with asthma, the parents are typically tasked with managing the child's condition. Establishing a collaborative partnership between parents and their child's primary physician is significant for improving asthma self-management among youth. Using the theory of reasoned action as a theoretical framework, this mixed-methods study examined whether a relationship exists between parental perceptions of physician cultural sensitivity and parental care in asthma treatment adherence. Phenomenology was used to explore the real-world experiences of study five ethnic minority parents and one guardian grandparent of asthmatic children aged 0–17 who shared similar perspectives. Descriptive surveys were used in combination with in-depth interviews to develop an understanding of parental perceptions on physician cultural sensitivity related to asthma treatment adherence. Overall, 108 minority parents were eligible to complete the survey. The study findings revealed that parents who feel recognized, valued, and respected by their child's physician were more likely to be engaged in shared decision-making about treatment. The findings support the potential for positive social change in terms of modifying the health care behaviors of minority parents with asthmatic children, increasing parental self-efficacy in managing their child's asthma, and improving the cultural sensitivity of physicians who serve the needs of diverse minority families.

Full textAbstract:
Diverse populations of students in public schools have led to differences in how the phrase parental involvement is understood. The problem at one local elementary preparatory school in urban Southern California was this varied understanding on what parental involvement entailed, specifically in school activities. The purpose of this study was to examine the perceptions of parents, teachers, and administrators regarding parental involvement and the influence of parental involvement on student academic progress. Bandura's theory of self-efficacy and Lee and Bowen's theory of social and cultural capital provided lenses into parental involvement and students' academic progress. A qualitative case study design was used with a purposeful sample of 5 parents, 8 teachers, and 3 administrators of 4th and 5th grade students at this preparatory elementary school. Individual interviews were transcribed and then subjected to constant comparative analysis until theoretical saturation occurred. Interpretations were then member-checked to ensure their credibility. Findings indicated all participants believed parental involvement was essential for students' academic progress, but differed in their views of the term itself. Parents believed involvement was ensuring homework completion, teachers believed parental involvement should be parent's engagement in every aspect of their child's life, and administrators believed parents were involved when they participated in school-wide committees. This project study is significant because the findings can be used by the local site leadership team to create workshops for parents, teachers, and administrators to help develop a common understanding of parental involvement and the influence parental involvement can have on student academic progress.

Full textAbstract:
The Internet of Things (IoT) has been acknowledged as one of the most innovative forms of technology since the computer, because of the influence it can have on multiple sectors of physical and virtual environments. The growth of IoT is expected to continue, by 2020 the number of connected devices is estimated to reach 50 billion. Recent developments in IoT provide an unprecedented opportunity for personalised services and other benefits. To exploit these potential benefits as best as possible, individuals are willing to provide their personal information despite potential privacy breaches. Therefore, this paper examines factors that influence the willingness to disclose personal information in the use of IoT in South Africa (SA) with the use of the privacy calculus as the theoretical underpinnings of this research. The privacy calculus accentuates that a risk-benefit trade off occurs when an individual decides to disclose their personal information, however, it is assumed that there are more factors than perceived risks and perceived benefits that influence information disclosure. After analysing previous literature, this study identified the following factors; information sensitivity, privacy concerns, social influence, perceived benefits, (perceived) privacy risks and privacy knowledge as possible key tenants in relation to willingness to disclose personal information. This research took on an objective ontological view, with the underlying epistemological stance being positivistic. The research incorporated a deductive approach, employing the use of a conceptual model which was constructed from a combination of studies orientated around privacy, the privacy calculus and the privacy paradox. Data for this research was collected using the quantitative research approach, through the use of an anonymous online questionnaire, where the targeted population was narrowed down to the general public residing within SA that make use of IoT devices and/or services. Data was collected using Qualtrics and analysed using SmartPLS 3. SmartPLS 3 was used to test for correlations between the factors which influence information disclosure in the use of IoT by utilising the complete bootstrapping method. A key finding was that the privacy paradox is apparent within SA, where individuals pursue enjoyment and predominantly use IoT for leisure purposes, while individuals are more likely to adopt self-withdrawal tendencies when faced with heightened privacy concerns or potential risks.

Full textAbstract:
Thin-film organic field effect transistors (OFETs) have attracted growing interest in recent years due to their promising electrical, optical and mechanical properties. Especially, oligothiophenes and their derivates are candidates with good prospects for application as the organic semiconducting material in such devices. They possess an extended, polarisable aromatic π-electron system that promotes a high structural arrangement of the molecules. The charge transport in the organic film is realised in the direction perpendicular to the plane of the thiophene rings via a hopping transport mechanism. Thus, a good π-π-overlap and a consequent stacking of the thiophene molecules in the film perpendicular to the gate substrate is essential to achieve excellent electric properties such as high charge carrier mobilities and low resistive losses.
The highly polarisable thiophene-based molecules are also very attractive materials that are potentially applicable as the field-sensitive organic semiconducting component of a ferroelectric OFET device. In such a device, the dielectric gate element of a conventional OFET setup is substituted by a ferroelectric substrate. The electric field that is induced by the polarisation of the ferroelectric material serves as gate field and controlls the charge injection and charge density inside the device.
In this thesis, thiophene-based molecules are investigated in detail with respect to their application as field-sensitive organic semiconducting component in a ferroelectric OFET device employing quantum-chemical ab initio and DFT-based methods. We demonstrate that the phosphonic acids can bind the organic molecules to the dielectric or ferroelectric material and well-anchored, robust self-assembled monolayers are formed. Furthermore, special focus is put on the influence of the intermolecular interactions among the organic molecules on the technologically relevant structural and electronic properties. It is found that the CN···HC hydrogen bond link the molecules into extended ribbons, but the π-π-stacking-stacking interaction is the main driving force in the self-assembly of the molecules. We also establish in detail the influence of the electric field on the phosphonic acid anchoring molecule and some quarterthiophene derivates.
For the latter, the strongest field-sensitivity is obtained for an external electric field aligned parallel to the extension of the thiophene framework. Hence, they are suitable to act as the field-sensitive organic components in devices that take advantage of a band-gap engineering. Moreover, the present results emphasise the importance of the adsorption morphology of the molecules in the film in a π-stacked fashion with their longitudinal axis oriented parallel to the (orthonormal) electric field induced by the ferroelectric substrate.

Full textAbstract:
In Nordic design of boiling water reactors, a deep water pool under the reactor vessel is employed for the core melt fragmentation and the long term cooling of decay heated corium debris in case of a severe accident. To assess the effectiveness of such accident management strategy the Risk-Oriented Accident Analysis Methodology has been proposed. The present work contributes to the further development of the methodology and is focused on the issue of ex-vessel debris coolability. The height and shape of the porous debris bed are among the most important factors that determine if the debris can be cooled by natural circulation of water. The bed geometry is formed in the process of melt release, fragmentation, sedimentation and packing of the debris in the pool. Bed shape is affected by the coolant flow that induces movement of particles in the pool and after settling on top of the bed. The later one is called debris bed self-leveling phenomenon. In this study, the self-leveling was investigated experimentally and analytically. Experiments were carried out in order to collect data necessary for the development of a numerical model with an empirical closure. The self-leveling model was coupled to a model for prediction of the debris bed dryout. Such coupled code allows to calculate the time necessary to have a coolable configuration of the bed. The influence of input parameters was assessed through sensitivity analysis in order to screen out the less influential parameters. Results of the risk analysis are reported as complementary cumulative distribution functions of the conditional containment failure probability (CCFP). Sensitivity analyses identified: effective particle diameter and debris bed porosity as the parameters that provide the largest contribution to the CCFP uncertainty. It is found that the effect of the initial maximum height of the bed on the CCFP is reduced by the self-leveling.Kokvattenreaktorer av nordisk typ har en djup vattenbassäng under reaktorkärlet som kan utnyttjas för att kyla härdsmältan och de fragmenterade härdresterna vid ett svårt reaktorhaveri. För att bedöma effektiviteten av en sådan haverihantering har man föreslagit användande av en riskorienterad metodik för haverianalysen (ROAAM, från engelska ”Risk-Oriented Accident Analysis Methodology”). Föreliggande projekt fokuserar på kylbarhet hos härdresterna utanför reaktortanken och bidrar till den pågående vidareutvecklingen av ROAAM till ROAAM+. Höjden på och formen för den porösa ansamlingen av härdrester (här också kallad partikelbädd) är bland de viktigaste faktorerna som avgör om resteffekten kan kylas bort med hjälp av naturlig cirkulation av vattnet i bassängen. Ansamlingens geometriska form skapas under hela processen från utsläpp av härdsmältan via fragmentering och sedimentering i bassängens botten. Formen kan sedan förändras med tiden genom att partiklar rör sig och omfördelas i kylflödet. Detta fenomen kallas en självnivellerande process. I detta arbete studeras denna självnivellerande process experimentellt och analytiskt. Experimenten utfördes i en särskild experimentuppställning utformad för att att samla in data och parametrar som behövs för att simulera fenomenet och utveckla en beräkningsmodell som sluts empiriskt. Denna modell kopplades sedan till en modell för beräkning av dryout i partikelbädden. Genom denna koppling av de två beräkningsprogrammen är det är möjligt att beräkna tiden för partikelbädden att nå en kylbar konfiguration. Inverkan av variationer i modellens indata studeras med hjälp av känslighetsanalys. Härigenom identifierades de minst inflytelserika parametrarna såsom effektiv drifttid, partikeldensitet, experimentell ovisshet i de empiriska samband som används för att sluta modellen, samt omlokaliseringstid efter det att reaktorn snabbstoppats (SCRAM). Dessa parametrar avfördes sedan från den fortsatta känslighetsanalysen. Ett artificiellt neuralt nätverk tränades för att användas i stället för den kopplade koden och möjliggöra den beräkningseffektivitet som krävs för att studera hur osäkerheter i indata förs vidare i riskanalysen. Resultaten är presenterade i form av komplementära, kumulativa fördelningsfunktioner för den betingade sannolikheten för brott på reaktorinneslutningen (CCFP, från engelska ”conditional containment failure probability”). Det visas att CCFP kan variera inom ett brett område beroende på de valda kombinationerna av frekvensfunktioner för ingångsparametrarna. Resultaten visar att effektiv partikeldiameter och hög porositet är de två parametrar som ger de största bidragen till osäkerheten i CCFP. Vi har också funnit att fenomenet självnivellering har en gynnsam inverkan på CCFP och leder till lägre utsläppsrisk. Det vore värdefullt att förfina de modeller som beskriver bildandet av den initiala partikelbädden. Detta är särskilt viktigt i de scenarier där det finns kort tid för självnivellering innan partikelbädden börjar smälta igen, dvs när man har relativt hög initial temperatur i partikelbädden och/eller hög specifik värmeeffekt.

The purpose of this study was two-fold. The first was to determine the degree of culturally responsive teaching practices and level of cultural competence of participants who teach upper elementary (grades three through six) STEM educators of predominantly Native Hawaiian students. The second purpose was to identify differences in cultural competence and culturally responsive teaching practices of those same participants identified above. These two participant groups were from the State of Hawaiʻi Department of Education’s Keonepoko and Pāhoa Elementary Schools. Both schools are from the Keaʻau-Kaʻu-Pāhoa Complex Area. The educators from Keonepoko were afforded knowledge and experiences from a culture-based professional development program known as the Moenahā School Program, while the educators from Pāhoa were not afforded these same knowledge and experiences. Using a quantitative, quasi-experimental design, data were collected via an online survey using three instruments: the Culturally Responsive Teaching Self-Efficacy Inventory (CRTSE), the Cultural Competence Self-Assessment Questionnaire (CCSAQ), and the Cultural Competence Self-Assessment Scale Demographic Information (CCSASDI). The data were analyzed using mean scores and those mean scores were compared for differences using a Mann-Whitney U test. The findings indicated the Moenahā participants had a statistically significantly higher level of cultural competence and higher degree of culturally responsive teaching practices than the non-Moenahā participants suggesting the importance of cultural competence professional development iii opportunities. These findings are applicable for teachers in schools with an higher Native Hawaiian student population.Ph. D.

Full textAbstract:
Nickel allergy is the most prevalent contact allergy and has been discussed as a possible riskfactor for hand eczema. However, hand eczema is one of the most frequently occurring skindiseases and has multifactorial origin. The aim of this thesis was to study the association between nickel allergy and hand eczema in the general population. There are only a fewpopulation-based studies previously published, that include patch testing. In addition, this thesis aimed to evaluate methods to follow the prevalence of nickel allergy.The study cohort consisted of 908 women who had been patch tested for the occurrence of nickel allergy as schoolgirls. Twenty years later, they were invited to participate in a follow-up questionnaire study. The response rate was 81%. In total, 17.6% of respondents reported handeczema after the age of 15 years and there was no statistically significant difference in the occurrence of hand eczema between those who were nickel-positive and those who were nickel negativeas schoolgirls. To further investigate possible links, another study was performed,which included a second questionnaire, a clinical investigation and patch testing. All schoolgirls from the baseline study who were still living in the area as adults were invited to participate and the participation rate was 77%. Patch test showed 30.1% nickel-positive individuals.When all participants were included in the analysis, there was no statistically significant difference between nickel-positive and nickel-negative women regarding occurrence of hand eczema. The most important risk factor for hand eczema was childhood eczema. Adjusted prevalence proportion ratio (PPR) for hand eczema after age 15 in relation to nickel patch testresults was 1.03 (95% CI 0.71--1.50) and in relation to childhood eczema 3.68 (95% CI 2.45--5.54). When women with and without history of childhood eczema were analyzed separately, the hand eczema risk was doubled in nickel-positive women without history of childhood eczema. In conclusion, the risk of hand eczema in nickel-positive women may previously havebeen overestimated. Next, the validity of self-reported nickel allergy was investigated. In the established cohort; two questions regarding nickel allergy were compared with patch test results. The validity of self-reported nickel allergy was low, and the questions regarding nickel allergy overestimated the true prevalence of nickel allergy. The positive predictive values were 59% and 60%. Another method for estimating the prevalence of nickel allergy, namely self-patch testing, was validated in the last study. In total, 191 patients from three different dermatology departments participated. The validity of self-testing for nickel allergy was adequate, with sensitivity 72%and proportion of agreement 86%.Nickelallergi är vanligt förekommande. Prevalensen i Skandinavien är 15--25% hos kvinnor och cirka 3% hos män. Sambandet mellan nickelallergi och uppkomst av handeksem har tidigare diskuterats och i vissa studier anges att 30--45% av alla individer med nickelallergi får handeksem. Det finns dock endast ett fåtal publicerade studier där personer ur normalbefolkningen har lapptestats för nickel. Handeksem ärvanligt och har ofta flera olika kombinerade orsaker. Det övergripande syftet med avhandlingen var att studera nickelallergins betydelse för uppkomst av handeksem. Detfinns ett intresse av att följa förekomsten av nickelallergi över tid, speciellt sedan det i början av 2000-talet infördes ett EU-direktiv som begränsar nickelinnehåll i klockor,smycken, metallknappar etc. Ytterligare ett syfte med avhandlingen var att utvärderaepidemiologiska metoder för att följa förekomsten av nickelallergi.Den första studien var en uppföljningsstudie av 908 flickor ur normalbefolkningen,vilka i skolåldern lapptestats med nickel. Tjugo år senare skickades en enkät till dessa kvinnor, svarsfrekvensen var hög (81%). Förekomsten av självrapporterat handeksemefter 15 års ålder var 17.6%. Det förelåg ingen signifikant skillnad i förekomst avhandeksem mellan de kvinnor som var nickelallergiska som barn jämfört med dem som inte var nickelallergiska. År 2006 utfördes ytterligare en studie, som inkluderade de kvinnor som fortfarande bodde i Örebro län. Studien omfattade en klinisk undersökning av händerna samt ett lapptest. 30% av kvinnorna var positiva för nickel.Det förelåg ingen signifikant skillnad i förekomst av handeksem mellan de som var positiva för nickel och de som var negativa. Vid separat analys av de kvinnor som angav tidigare barneksem jämfört med dem som aldrig hade haft barneksem visade det sig att risken för handeksem var dubbelt så stor hos nickelallergiker i den gruppen som aldrig hade haft barneksem. Båda studierna visade att barneksem var den största riskfaktorn för att få handeksem som vuxen, med en 3-4 gånger ökad risk. Den tredje studien var en validering av självrapporterad nickelallergi. Överensstämmelsen var låg mellan enkätfrågor gällande nickelallergi och lapptestverifierad nickelallergi. Av dem som själva bedömde sig vara nickelallergiska var endast 59% positiva enligt lapptest. För att följa förekomsten av nickelallergi i befolkningen behövs därför andra metoder. I den fjärde studien utvärderades ett självtest för nickelallergi. 191 patienter från tre olika hudkliniker i Sverige deltog i studien. Validiteten för metoden självtest var tillfredsställande, sensitiviteten var 72%och graden av överensstämmelse var 86%.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel SuperiorObjetivos: comparar os achados do auto-exame das mamas com o seu exame clÃnico no rastreamento de anormalidades mamÃrias. Verificar a freqÃÃncia dos conhecimentos e prÃticas relacionadas com o auto-exame das mamas. Estimar a sensibilidade e especificidade do auto-exame das mamas em relaÃÃo ao seu exame clÃnico. Averiguar se a sensibilidade à influenciada pelas variÃveis antropomÃtricas e sociodemogrÃficas ou pelos conhecimentos e prÃticas do auto-exame. Metodologia: estudo transversal de validaÃÃo de teste diagnÃstico, envolvendo 505 funcionÃrias de um hospital universitÃrio. Foi aplicado um questionÃrio sobre conhecimentos e prÃticas relacionadas com o auto-exame das mamas e ministrada instruÃÃo sobre o auto-exame a todas as participantes que posteriormente realizaram o auto-exame e foram submetidas a exame clÃnico por Ãnico examinador. Os intervalos de confianÃa de 95% foram calculados pelo mÃtodo de aproximaÃÃo pela distribuiÃÃo normal. ProporÃÃes foram comparadas por meio do teste do qui-quadrado e foram consideradas significativamente diferentes (teste bicaudado) quando a probabilidade de estas serem semelhantes foi menor ou igual a 0,05. Resultados: 94,06% tinham recebido informaÃÃo sobre o auto-exame, 29,90% pelo mÃdico. 32,28% realizavam o auto-exame mensalmente, 55,95% apÃs a menstruaÃÃo e o procedimento mais realizado era a palpaÃÃo durante o banho. A sensibilidade para qualquer achado foi de 37,21 % com IC 95% de 32,77%-41,82%. A sensibilidade, excluindo-se a assimetria, foi de 44,85% com IC 95% de 39,59-50,26%. A sensibilidade exclusiva para nÃdulo e espessamento (massa) foi de 52,07% com IC 95% de 43, 17%-60,87%. A especificidade para qualquer achado foi de 71,64% com IC 95% de 60,00%Â81,44%. A especificidade, excluindo-se a assimetria, foi de 80,57% com IC 95% de 74,20%-85,93%. A especificidade exclusiva para massa foi de 90,10% com IC 95% de 86,81 %-92,79%. A sensibilidade nÃo mostrou diferenÃa estatisticamente significativa quando estratificada por mama, conhecimentos e prÃticas relacionadas ao exame feito pela prÃpria e variÃveis antropomÃtricas e sociodemogrÃficas. ConclusÃo: o auto-exame à bastante conhecido por essa populaÃÃo, apresenta em relaÃÃo ao exame clÃnico uma baixa sensibilidade e especificidade, que se eleva quando analisadas exclusivamente as massas, aproximando-se da sensibilidade e especificidade da mamografia em mulheres abaixo dos 40 anos de idade

Grill, Kalle. "Anti-paternalism." Licentiate thesis, KTH, Philosophy and History of Technology, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-4065.
Full textAbstract:
This is a thesis about anti-paternalism – the liberal doctrine that we may not interfere with a person’s liberty for her own good. Empirical circumstances and moral values may certainly give us reason to avoid benevolent interference. Anti-paternalism as a normative doctrine should, however, be rejected.
Essay I concerns the definitions of paternalism and anti-paternalism. It is argued that only a definition of paternalism in terms of compound reason-actions can accommodate its special moral properties. Definitions in terms of actions, common in the literature, cannot. It is argued, furthermore, that in specifying the reason-actions in further detail, the notion of what is self-regarding, as opposed to other-regarding, is irrelevant, contrary to received opinion.
Essay II starts out with the definition of paternalism defended in essay I and claims that however this very general definition is specified, anti-paternalism is unreasonable and should be rejected. Anti-paternalism is the position that certain reasons – referring one way or the other to the good of a person, give no valid normative support to certain actions – some kind of interferences with the same person. Since the reasons in question are normally quite legitimate and important reasons for action, a convincing argument for anti-paternalism must explain why they are invalid in cases of interference. A closer look at the reasons and actions in question provides no basis for such an explanation.
Essay III considers a concrete case of benevolent interference – the withholding of information concerning uncertain threats to public health in the public’s best interest. Such a policy has been suggested in relation to the European Commission’s proposed new system for the Registration, Evaluation, and Authorisation of Chemicals (REACH). Information about uncertain threats to health from chemicals would allegedly spread anxiety and depression and thus do more harm than good. The avoidance of negative health effects is accepted as a legitimate and good reason for withholding of information, thus respecting the conclusion of essay II, that anti-paternalism should be rejected. Other reasons, however, tip the balance in favour of making the information available. These reasons include the net effects on knowledge, psychological effects, effects on private decisions and effects on political decisions.
