Armstrong, Jessica Lee. "Internalized Shame and Shame Tolerance in Inpatient Treatment for Substance Use Disorders." Thesis, Clark University, 2017. http://pqdtopen.proquest.com/#viewpdf?dispub=10288589.
Full textAbstract:
Internalized shame, a construct that assesses the extent to which an individual identifies with the experience of feeling deeply flawed, unworthy, and defective (Cook, 1987, 1991, 2001), has been associated with negative clinical outcomes in substance use disorders (SUDs; Harper, 2011). Tolerance for shame-related distress, or shame tolerance, has been associated with other forms of psychopathology (Schoenleber & Berenbaum, 2010, 2012), and may serve to moderate the relationship between internalized shame and SUD treatment outcomes. This mixed-methods study explores internalized shame and shame tolerance in the context of early recovery from SUDs, particularly as they are associated with inpatient treatment success and participant experiences with relapse. Self-report measures and interviews were used, and thematic analysis (Braun & Clarke, 2006) was utilized in analyzing qualitative data. Quantitative analyses did not find support for the moderating effects of shame tolerance on the impact of internalized shame on treatment outcomes in individuals with SUDs in inpatient treatment. However, there was a significant interaction between gender, prior relapse, and internalized shame, such that women with prior relapse presented with higher internalized shame and lower shame tolerance than women with no prior relapse or men in either condition. A semi-structured interview and subsequent qualitative analyses were utilized to explore participant experiences with relapse and treatment. Results revealed superordinate and subthemes related to each of three content areas – relapse experiences, abstinence in response to craving, and current treatment experiences – and interview excerpts are included to highlight each theme. Clinical implications, limitations, and future directions are discussed.

Barratt, Joanne. "An exploration of shame in PTSD treatment and psychosis." Thesis, University of Warwick, 2015. http://wrap.warwick.ac.uk/76647/.
Full textAbstract:
This thesis is an exploration of shame in Post-Traumatic Stress Disorder and Psychosis. It begins with a systematic review considering the effectiveness of psychological treatment for PTSD in reducing shame. The literature search revealed 16 articles which were included in the review. The reviewed literature suggested existing PTSD treatments effectively reduce feelings of shame and PTSD symptoms. No particular treatment or intervention component was indicated to be more effective for reducing shame in PTSD. The second chapter reports on a quantitative study that explored the relationship between shame, childhood trauma, delusional beliefs, auditory hallucinations and fears of compassion. Self-report questionnaires were completed by 30 people with psychosis. The results showed people who reported childhood trauma also reported higher levels external shame. People who reported more feelings of external shame also reported higher levels of internal shame. There was a relationship between internal shame and delusional beliefs. Fears of compassion were found to correlate with shame and delusional beliefs. Shame was not shown to mediate between childhood trauma and delusional beliefs or auditory hallucinations. The findings are considered in relation to previous research, theoretical models and therapeutic models. Clinical implications and future research are also discussed. The final paper is a reflective account of the researcher’s experiences of conducting sensitive research with a vulnerable client group. Specific consideration is afforded to the impact of the research on clinicians, participants, as well as the researcher. The journey from the idea development through to its completion is deliberated.

Full textAbstract:
The purpose of the study was to test for theoretic trends of guilt' shame (quadratic) and defensiveness (linear) across treatment for alcoholic patients. The study sample consisted of91 participants. These included adult males who were in either outpatient or inpatient treatment for alcoholism.All participants were administered a questionnaire comprised of guilt, shame, and defensiveness measures. The questionnaires also asked self rating questions as a measure of progress and had a therapist section for progress ratings. Three null hypotheses were tested using trend analysis. Two way analyses of variances were also used to examine progress variables.ResultsIt was hypothesized that guilt and shame would demonstrate quadratic relationships across treatment and that defensiveness would demonstrate a linear relationship. None of the trend 2analyses demonstrated the expected relationships. The post-hoc two-way analyses of differences in guilt, shame, and defensiveness as a function of both weeks-in-treatment and progress measures yielded few significant results.Conclusions The results of this study do not support some of the major premises concerning treatment of the alcoholic patient. Research needs include operationally defining treatment approaches and refining concepts and measures.Department of Counseling Psychology and Guidance Services

Full textAbstract:
The purpose of this study is to examine the degree to which licensed psychologists are aware of the impact of shame as an underlying cause for various types of psychopathology in clinical and forensic settings. As a self-conscious emotion underlying numerous psychodynamic concepts, shame has largely been disregarded in the mostly behavior-based diagnoses described in the Diagnostic and Statistical Manual of the American Psychiatric Association (American Psychiatric Association, 2000). However there is significant research supporting the importance of shame for conceptualization in both clinical interventions and forensic assessments. In order to examine the degree of awareness of the concept of shame as presented in numerous forensic and clinical studies, a survey was designed and disseminated among members of the American Psychological Association, the California Psychological Association, the Los Angeles County Psychological Association, the Forensic Mental Health Association of California, and the American Academy of Forensic Psychology. Although limited by small sample size, results indicated a general lack of appreciation of the importance of shame. Neither workplace setting, nor the type of educational background, nor the number of years in practice significantly predicted the number of questions answered correctly in the survey about shame. However, participants with a Psy.D. degree, in Institutional settings tended to answer guilt a significantly greater number of times than their Ph.D. non-institutional setting peers, particularly when they had been practicing for a shorter amount of time than those peers.

Full textAbstract:
Background: Eating disorders are commonly occurring illnesses that frequently cause substantial physical, emotional and psychosocial impairments (Fairburn, et al., 2008). The prevalence of this debilitating condition has led to substantial efforts by researchers and clinicians to search for different ways of understanding the illness for the sole purpose of increasing the presently poor treatment outcomes. Existing theoretical and research literature looking at the role of shame and guilt in eating disorders have put forward a convincing assertion that shame and guilt are poignant features in the psychopathology and symptomatology of the condition. However, these reports have not provided in-depth explanation into how people suffering from eating disorders experience shame and guilt and very little qualitative research has been conducted in this area. Likewise, the interwoven relationship and the differences between shame and guilt and their role in eating disorders psychopathology and symptomatology remain unclear. Aims and Method: The present study is an Interpretative Phenomenological Analysis (IPA) that recognises the uniqueness of an individual’s experience of complex phenomenon such as eating disorder. Thus it aims to explore the understanding and sense-making of shame and guilt experiences by listening to the voices of six people who have been diagnosed and treated for eating disorders using semi-structured interviewing method. The study also explores the role of shame and guilt in treatment particularly their implication in the disclosure of information in the course of treatment. Findings and Discussion: The analysis identified five main themes; the intensity of shame and guilt experience AND the pervasiveness of shame and guilt experience, Guilt and shame as integrated into all facets of the ED, Existential questioning of identity, shame and guilt lived out and developed in different context/ Locus of responsibility. Contribution to knowledge: The study provides deeper understanding of participants’ subjective experience of shame and guilt. The study highlights that shame and guilt are experiences that are intertwined with all facets of eating disorders as well as the individual’s identity. Finally, shame and guilt were described as experiences that negatively impacted on treatment process. The implications of this for counseling psychology practice are discussed, and suggestions for future research are made.

Full textAbstract:
The literature has indicated that frequently examined patient variables at intake have shown mixed results in the prediction of dropout from outpatient substance abuse treatment. In this research sociodemographic characteristics, substance use and psychological problem severity at intake were examined as predictors of early dropout in 411 patients enrolled in a 6-month outpatient substance abuse treatment program. Early dropout was defined as participation of less than 6 weeks, the first phase of treatment. Another focus of the research was to determine how patients who dropped out of treatment early fared in terms of substance use at 6 months compared to those retained longer. It was found that being younger, unmarried or not cohabitating, and having a greater severity of employment problems at intake were associated with early treatment dropout. Substance abuse and psychological problem severity at intake were not associated with dropout from the first phase of treatment. Patients who left treatment early had some reduction in alcohol consumption at 6-month follow-up, but overall, those retained in treatment longer had better alcohol and drug use outcomes at 6 months. Both the outcomes on retention and substance use were examined in order to explore possible solutions to dropout from the perspective of health services. Despite the improvements in substance abuse for patients retained longer than 6 weeks, it was determined that only 40% of patients were retained for 6 months, thereby indicating that the majority of patients had not received the planned 6-month intervention. In response to these facts, a brief intervention consisting of 5 individual therapy sessions based on coping skills and motivational enhancement strategies was designed and manualized with participation of the clinical staff. Following this, a randomized clinical trial was conducted with 72 patients, and substance use at 6-month follow-up was compared between the brief intervention and the conventional treatment groups. At 6 months, both the brief intervention and conventional treatment groups had reductions in alcohol use compared to intake, but no conclusions could be made about drug use. The implications of the findings for substance abuse treatment service delivery are discussed.

Full textAbstract:
Aim The aim of this qualitative study was to explore Indonesian nurses’ experiences of patient education and patients’ adherence to TB treatment. Background Tuberculosis (TB) is an infectious disease that 9.6 million people in the world suffer from. Indonesia is one of the world’s 22 high-burden countries with over 320.000 cases of TB in 2014. The UN’s (United Nation) goal is to have ended the TB epidemics by the year 2030. Nurses play a central role in accomplishing adherence to treatment and prevention of TB. Method To fulfil the aim a qualitative method using semi-structured interviews was used. The interviews were recorded and transcribed. The transcribed data was analysed by using a qualitative content analysis with a manifest approach. Findings The findings, based on the result of nine interviews, showed four themes: “Strategies for patient education”, “Factors affecting patient education and adherence to treatment”, ”Outcomes of patient education” and ”Feelings and opinions about patient education”. Conclusion This study showed that the nurses use different strategies when practicing patient education. It was also shown that the nurses are well aware about patient-related factors and how they affect patient education and adherence to TB treatment. Keywords Tuberculosis, nursing care, patient education, adherence

Full textAbstract:
Nickel-Titanium (NiTi) shape memory alloys have been the focus of extensive research due to its unique characteristics such as high recoverable strain and ductility. However, solutionized samples of NiTi do not demonstrate good shape memory characteristics due to low strength for dislocation slip. Thermo-mechanical treatments are required to strengthen the matrix and improve the shape memory characteristics. Plastic deformation and the subsequent annealing is the common way to improve shape memory properties. In this case, deformation magnitude, temperature, rate, mechanism, and annealing temperature and time are all important parameters for the final shape memory properties. Equal channel angular extrusion (ECAE) is a well-known technique to severely deform materials by simple shear with no change in cross-section. In this study, Ti- 49.8 at% Ni samples are deformed by ECAE at three different temperatures near transformation temperatures. X-ray analysis, calorimetry, transmission electron microscopy and thermo-mechanical cycling techniques are utilized to investigate the effects of severe deformation and subsequent annealing treatment on shape memory properties. Martensite stabilization, formation of strain induced B2 phase, change in transformation temperatures, formation of new phases, recrystallization temperature, texture formation, and increase in strength and pseudoelastic strain are the main findings of this study.
Co-32.9 at% Ni-29.5 at% Al is a newly found ferromagnetic alloy. Its low density, high melting temperature and cheap constituents make the alloy advantageous among other shape memory alloys. Although some magnetic properties of this alloy are known, there is no report on basic shape memory characteristics of CoNiAl. In this study, effect of thermo-mechanical treatments on the microstructure and shape memory characteristics such as transformation behavior, pseudoelasticity, stages of transformation, temperature dependence of the pseudoelasticity, response to thermal and stress cycling is investigated. Formation of second phase along the grain boundaries and inside the grains, about 4% pseudoelastic and two-way shape memory strain, very narrow stress hysteresis, large pseudoelastic window (>150°C), two-stage martensitic transformation, stable response to cyclic deformation, high strength for dislocation slip, slope of Clasius-Clapeyron curve, and twinning plane are determined for the first time in literature.

Fuller, Jeannette. "Are guilt and shame in male forensic patients linked to treatment motivation and readiness?" Thesis, University of Surrey, 2017. http://epubs.surrey.ac.uk/841667/.
Full textAbstract:
This thesis includes the research, assignments and clinical placements that were undertaken for the degree of Doctor of Psychology (Clinical Psychology). The Major Research Project was focused on the concepts of guilt and shame and treatment motivation and readiness in forensic patients. Treatment motivation and readiness are important considerations in forensic settings. Models and theories of these concepts suggest affective factors such as the experience of guilt and shame are likely to have some impact on motivation and readiness for treatment. These models have been validated in general forensic settings, but although applied to forensic mental health settings, the validity of the different aspects of these models has not been directly examined with forensic mental health patients. This thesis aimed to investigate whether there was any relationship between guilt and shame and motivation and readiness for treatment in a sample of forensic patients. Part one of this thesis presents a narrative review of guilt and shame in forensic mental health participants. The findings of the review suggested that guilt and shame were relevant emotional experiences for forensic patients. Links between these emotions and motivation and readiness for treatment had not been empirically tested. Part two presents an empirical paper that investigated the association between guilt and shame and treatment motivation and readiness in patients residing in forensic mental health settings. The findings suggested that offence-related guilt was associated with readiness for treatment, whereas shame did not have a relationship with motivation or readiness. Part three presents a summary of clinical experience gained within this training programme and Part four contains the assessments completed during training.

Full textAbstract:
The purpose of my research was to investigate the sources of heterogeneity in cellular decisions that are based on both external and internal cues. I used the signaling network induced by tumor necrosis factor (TNF) as a model system to examine how the duration of a stimulus and cell shape may affects signaling and cellular decisions. First, using a microfluidic device to achieve fine control of the ligand delivery to cells, my colleagues and I found that the duration of TNF stimulation is a factor that coordinates cell fate decisions in single cells. Specifically, we found that a few seconds of exposure to TNF is sufficient to activate the NF-κB pathway and induce apoptotic cell death and that, strikingly, a 1-min pulse of TNF can be more effective at killing cells than a 1-hour pulse. Second, to study the effects of cell shape, I used a two-pronged approach. Initially, I used live-cell imaging and single-molecule fluorescence in situ hybridization (smFISH) to examine whether descriptors of cell shape correlate with NF-κB nuclear translocation and NF-κB-dependent transcription in unperturbed populations of single cells. Next, I used surface micro-patterning to impose different geometry and degrees of spreading on cells and examine NF-κB-dependent transcription in these cells. I found that descriptors that quantify cell spreading, such as cell area and nuclear area, correlate with NF-κB nuclear translocation and NF-κB-dependent transcription. In addition, imposing bigger amount of spreading on cells increased the transcript abundance for two NF-κB-dependent genes, A20 and IκBα. In contrast, the relationships between geometry-related cell shape descriptors and NF- κB-dependent transcription are more subtle and complex. Importantly, despite observing the correlations between cell spreading and NF-κB activity, I found that the effects of cell shape on NF-κB dynamics and on NF-κB-dependent transcription were small. Together, my investigations of TNF-induced signaling have shown that while the duration of treatment encodes information used in the TNF-induced cell death decision, NF-κB dynamics and NF-κB-dependent transcription are quite robust to changes in cell shape.Medical Sciences

Full textAbstract:
Ti-Ni phase transformation behaviour is very sensitive to the thermal and mechanical history of the alloy. Thermomechanical cycling through the full transformation range may degrade the Ti-Ni functional properties (functional fatigue). These repeated transformation cycles cause changes in the SMA phase transformation behaviour due to the formation and accumulation of defects in the alloy microstructure.
The main objective of this thesis is to establish the relationships between the changes in Ti-Ni phase transformation behaviour caused by thermomechanical processes, especially in the R-phase range, and the functional properties of the Ti-Ni shape memory alloys (SMAs). Establishing these relationships should allow us to find appropriate thermomechanical processes to substantially improve the Ti-Ni one-way and two-way shape memory effects.
To achieve this objective, several experimental techniques are used including measuring variations of the electrical resistivity with temperature, X-ray diffraction, isothermal tension testing, thermal cycling under constant stress, and thermal cycling under zero stress.
This study of the phase transformation changes caused by thermomechanical processes has led to a new way of interpreting resistivity curves for calculating the transformation temperatures. Moreover, we have determined how the R-phase influences the functional properties of SMA and, finally, we have substantially improved the properties of one-way and two-way shape memory effects by using thermal processes that avoid permanent deformation of the alloy.Las transformaciones de fase en aleaciones de NiTi son altamente dependientes de la composición de la aleación, así como de la historia térmica y mecánica previa al uso de la SMA. El objetivo principal de esta tesis es establecer los vínculos existentes entre los cambios producidos en las transformaciones de fase por procesos termomecánicos y las propiedades funcionales en aleaciones con memoria de forma de Ti-Ni, tal que nos permita hallar los procesos termomecánicos más adecuados que proporcionen una mejora substancial en las propiedades funcionales de estas aleaciones. La determinación de estas relaciones, prestando especial atención a la fase-R, nos debe proporcionar las claves para incrementar las propiedades de memoria de forma y doble memoria de forma. Para la consecución de este objetivo se han usado diferentes técnicas de caracterización experimental: variación de la resistividad eléctrica con la temperatura (ER), difractometría de rayos X (DRX), ensayos de tracción isotérmicos, ciclados térmicos a tensión constante y ciclados térmicos a tensión nula. A través del estudio exhaustivo de las transformaciones de fase, se ha aportado una nueva interpretación de las curvas de resistividad para el cálculo de las temperaturas de transformación, se ha determinado la influencia de la fase-R en las propiedades funcionales de las SMA y se han mejorado substancialmente las propiedades de memoria simple y doble memoria de forma mediante procesos térmicos que evitan deformaciones permanentes antes del uso de la aleación.

La determinació d'aquestes relacions, prestant especial atenció a la fase-R, ens ha de proporcionar les claus per incrementar les propietats de memòria de forma i doble memòria de forma.

A través de l'estudi exhaustiu de les transformacions de fase, s'ha aportat una nova interpretació de les corbes de resistivitat per al càlcul de les temperatures de transformació, s'ha determinat la influència de la fase-R en les propietats funcionals de les SMA i s'han millorat substancialment les propietats de memòria simple i doble memòria de forma mitjançant processos tèrmics que eviten deformacions permanents abans de l'ús de l'aliatge.

Full textAbstract:
Hydraulic fracturing operations utilized for shale gas production result in the generation of a large volume of flowback and produced water that contain suspended material, salts, hydrocarbons, metals, chemical additives, and naturally-occurring radioactive material. The water is impounded at drilling sites or treated off-site, resulting in significant generation of residual solids. These are either buried on site or are disposed in lined landfills. The objective of this study was to determine the levels of heavy metals and other elements of concern that will leach from these residual solids when placed in typical disposal environments.
For this purpose, laboratory leaching experiments were employed wherein representative samples were brought into contact with a liquid to determine the constituents that would be leached by the liquid and potentially released into the environment. The samples used included sludge resulting from the physicochemical treatment of process water (TS), sludge solidified with cement kiln dust (SS), raw solids obtained by gravity separation of process water (RS), and drilling mud (DM). The samples were subjected to both single extraction (i.e. Shake Extraction Test, SET) and multiple extraction (i.e. Immersion Test, IT) leaching tests. For the shake extraction test, samples were mixed with a specific amount of leaching solution without renewal over a short time period. In the immersion test, samples were immersed in a specific amount of leaching solution that was periodically renewed over a longer period of time. For both these tests, analyses were performed on the filtered eluate. The tests were performed as per standards with modifications. Distilled de-ionized water, synthetic acid rain (pH ~ 4.2), weak acetic acid (pH ~ 2.88), and synthetic landfill leachate were used as leaching solutions to mimic specific disposal environments.
Alkali metals (Li, K, Na), alkaline earth metals (Ba, Ca, Mg, Sr) and a halide (Br), which are typically associated with Marcellus shale and produced waters, leached at high concentrations from most of the residual solids sample. The SS sample, due to its stabilization with CKD, had a lower extraction efficiency as compared to the unconsolidated TS and RS samples. In EF 2.9 and EF SLL, the leaching took place under acidic conditions, while for EF DDI and EF 4.2, the leaching occurred in alkaline conditions. EF 2.9 and EF SLL were determined to be the most aggressive leaching solutions, causing the maximum solubility of most inorganic elements. Thus, high amounts of most EOCs may leach from these residual solids in MSW landfills disposed under co-disposal conditions. Agitation, pH and composition of the leaching solution were determined to be important variables in evaluating the leaching potential of a sample.
The results of this study should help with the design of further research experiments being undertaken to develop environmentally responsible management/disposal strategies for these residual solids and also prove useful for regulatory authorities in their efforts to develop specific guidelines for the disposal of residuals from shale gas production operations.Master of Science

Full textAbstract:
Oil and gas were recovered from alum shale (black shale) at Kvarntorp, Närke,during a period of 24 years. One of the remnants of this industry is a 100 m highdeposit with high contents of uranium, arsenic, molybdenum, vanadium and otherelements. Presently the leakage of metals from the deposit into nearby streams israther modest but will most likely accelerate in the near future. One way to preventan uncontrolled leakage of these elements from the deposit into the environmentwould be to install a filter with an effective adsorbent that after saturation could easilybe regenerated and reused. The filter could not only be used to reduce the impact ofmetal leakage to the environment but also to reclaim valuable elements like nickel,vanadium, uranium and molybdenum. Unfortunately such a filter does not existtoday, but there are a wide range of minerals that have high adsorbing capacities andcould serve as filter components in a mineral barrier system. The adsorbingproperties of some natural minerals with respect to selected metals that are abundantin the Kvarntorp deposit are studied in this project. These minerals are bentoniteclay, (burnt clay), unburnt shale (stybb), burnt shale (rödfyr), apatite, peat andbark. In the experiments each sorbent was blended with artificial groundwater and acertain amount of metal stock solution. Samples were taken at five different pH.The results show that the two shale-products stand out from the othersand have the best adsorbing qualities for nickel, copper and zinc. At a pH over 7between 96 and 99% of the metal ions were removed from the solution.Unburned shale especially shows remarkably good results for vanadiumthroughout the tested pH range of 3,4-7,7 between 98 and 99% of the vanadium ionswere removed from the solution. Unburned shale performs best of the testedadsorbents and could probably be used as an adsorbent in a geological barrier butmore research is needed.

Full textAbstract:
Obesity and weight-management is primarily focused on improving diet, nutrition and activity levels. Some research suggests that psychological interventions may have a role in weight-management. This thesis sought to better understand whether there is a role for the use of psychological approaches in obesity. Literature Review: A review of literature examining the efficacy of cognitive-behavioural therapy (CBT) as a treatment for weight management was conducted. Ten quantitative studies were included in the review. The evidence showed that CBT had a positive effect on weight-loss in both short and long-term studies and was superior to treatment as usual, minimal or no treatment conditions. The literature was critically appraised and clinical implications were discussed. Research Report: The empirical paper examined the role of self-conscious emotions, such as shame, self-esteem and self-compassion along with psychological distress. These have emerged as important factors in the development and maintenance of eating disorders. These were investigated with regards to their relationship with eating behaviours (emotional eating, uncontrolled eating and restraint), as well as eating disorder psychopathology in a clinically obese population. Treatment-seeking obese adults (N=53) were recruited from a dietetic clinic and a range of psychometric measures completed. High levels of shame, distress and eating disorder psychopathology were shown when compared to other non-clinical populations. Results showed high levels of uncontrolled eating, and emotional eating. Internal shame was shown to have a unique contribution in the explanation of emotional eating. A number of significant positive correlations were found with shame, including emotional and uncontrolled eating. Although the sample size was small, the results indicated that shame might have an important role in eating behaviours. Psychological interventions addressing self-conscious negative emotions may be useful in weight management interventions.

Full textAbstract:
Removal of xylene (a toxic compound) from aqueous solution by modified multi wall carbon nano tubes
(MWCNT) via silica as sheeted carbon nanotube (SCNT) was evaluated. The physicochemical properties of
MWCNT such as structure and availability surface were improved due to convert tubes into sheets that
cause significantly increase in xylene adsorption. The equilibrium amount (qe (mg/g)) in nano material's
dose of 1g/l, xylene concentration of 10mg/l, contact time of 10min, and pH 7, for SCNT (qe 9.8 mg/g) was
higher than single wall carbon nano tubes (SWCNT) (qe 9.2 mg/g) and MWCNT (qe 8.9 mg/g). It is concluded
that sheeted carbon nanotube due to their large surface area improve performance of xylene adsorption.
Also carbon nano tube (CNT) recycling by heating, showed better adsorption performance for recycled
SCNT. A comparison study on xylene adsorption revealed that sheeted carbon nanotube has better xylene
adsorption performance as compared to CNT, carbon and silica adsorbents. This suggests that the SCNT is
an efficient adsorbent for xylene removal in environmental pollutions cleanup.

Full textAbstract:
This thesis studied a new minimally invasive implant for scoliosis correction that aims to correct the deformity without fusing the spine, thereby allowing movement and growth in the spine following surgery. The effect of two different vertebral body implant (staple) designs on the stiffness of the spine, using calf spines as an in vitro model, was studied. The results showed that the implants decreased spinal stiffness, with associated potential damage to the growth plates due to the staple tips. There were no significant differences in stiffness between the two staple designs tested.

Zapoticla, Frank. "The Effects of Applied Strain and Heat Treatment on the Properties of NiTi Wire During Shape Setting." DigitalCommons@CalPoly, 2010. https://digitalcommons.calpoly.edu/theses/378.
Full textAbstract:
NiTi components are commonly subjected to thermo-mechanical heat treatments during production and fabrication. This study investigates the effects of applied strain of 0-10% and heat treatments of 300-600ºC for times of 2-30 minutes during shape-setting of Ti–50.8 at% Ni wire with a nominal diameter of 0.495 mm and an initial transition temperature, Af, of 12ºC. Strain was applied prior to heat treatments by coiling NiTi wire, essentially producing coiled springs, around different diameter steel mandrels to obtain different strain levels. The samples of NiTi wire under applied strain were heat treated in a salt bath, followed by a rapid quench. Transformation temperatures and mechanical properties were characterized using the differential scanning calorimeter and tensile tests. Changes in the Af, UTS, and elastic modulus due to ageing processes and applied strain were observed. Following theory, precipitation rates of Ni-rich phases generally increased with increased temperature (up to a certain point), time and applied strain levels. Reaction rates to achieve a particular Af might be faster than expected if the sample is under strain during the shape-setting process. Due to precipitation strengthening, an increase in UTS with increased heat treatment time was observed between 300-450°C; annealing processes dominate at higher temperatures, resulting in a decrease in UTS above 500°C. A decrease in UTS with increasing level of applied strain was observed. Trends in elastic modulus were highly inconsistent in this study. As shown by this study, applied strain in NiTi during heat treatment affects the Af and mechanical properties.

Full textAbstract:
Traditionally, uncertainties are handled by expanding the irradiated volume to ensure target dose coverage to a certain probability. The uncertainties arise from e.g. the uncertainty in positioning of the patient at every fraction, organ motion and in defining the region of interests on the acquired images. The applied margins are inherently population based and do not exploit the geometry of the individual patient. Probabilistic planning on the other hand incorporates the uncertainties directly into the treatment optimization and therefore has more degrees of freedom to tailor the dose distribution to the individual patient. The aim of this thesis is to create a framework for probabilistic evaluation and optimization based on the concept of dose coverage probabilities. Several computational challenges for this purpose are addressed in this thesis. The accuracy of the fraction by fraction accumulated dose depends directly on the accuracy of the deformable image registration (DIR). Using the simulation framework, we could quantify the requirements on the DIR to 2 mm or less for a 3% uncertainty in the target dose coverage. Probabilistic planning is computationally intensive since many hundred treatments must be simulated for sufficient statistical accuracy in the calculated treatment outcome. A fast dose calculation algorithm was developed based on the perturbation of a pre-calculated dose distribution with the local ratio of the simulated treatment’s fluence and the fluence of the pre-calculated dose. A speedup factor of ~1000 compared to full dose calculation was achieved with near identical dose coverage probabilities for a prostate treatment. For some body sites, such as the cervix dataset in this work, organ motion must be included for realistic treatment simulation. A statistical shape model (SSM) based on principal component analysis (PCA) provided the samples of deformation. Seven eigenmodes from the PCA was sufficient to model the dosimetric impact of the interfraction deformation. A probabilistic optimization method was developed using constructs from risk management of stock portfolios that enabled the dose planner to request a target dose coverage probability. Probabilistic optimization was for the first time applied to dataset from cervical cancer patients where the SSM provided samples of deformation. The average dose coverage probability of all patients in the dataset was within 1% of the requested.

Full textAbstract:
Abstract
Whenever a foreign material is implanted into a human body an implant–tissue interface area forms between them. In this microenvironment, interactions take place between the implant and the surrounding tissue. The implantation of a biomaterial into tissue results in injury and initiation of the inflammatory response. This host response to biomaterials is an unavoidable series of events that occur when tissue homeostasis is disturbed by the implantation process. In bone tissue, biocompatible implants must initially be capable of strong bone implant contact and subsequently, allow the normal bone remodeling cycle around the implant.
NiTi is a metal alloy composed of approximately a 50:50 ratio of nickel and titanium. It possesses shape memory and superelasticity properties, which make it an interesting biomaterial. NiTi has two phases: austenite and martensite. A decrease in temperature or applied stress induce the austenite-to-martensite transformation. Heating or removing the stress restores the parent austenite phase. The alloy in its martensite structure can be reshaped and strained several times more than a conventional metal alloy without irreversible deformation of the material. The alloy returns to its original shape as it changes from martensite-to-austenite. This transformation is seen as the macroscopic shape memory effect.
This study further investigated the biocompatibility of NiTi, especially the bone cell response to both austenite and martensite. Different surface treatments were investigated in order to improve and possibly even control NiTi's bioactivity as a bone implant material.
Osteoclasts grew and attached well on the austenite NiTi phase, but the results indicated that the biocompatibility of martensite NiTi was compromised. Oxidation of the NiTi surface improved osteoblast attachment and viability. This was due to the formation of a TiO2 surface layer of moderate thickness. Coating the NiTi surface with the extracellular matrix protein fibronectin was shown to enhance osteoblast proliferation and increase the number of cells in the G1 cell cycle stage. Austenite was more prone to show these effects than martensite. A sol-gel derived titania-silica surface treatment was observed to increase the bone implant contact of functional NiTi intramedullary nails. The surface treatment was most effective with the constant bending load provided by the NiTi nail.

Full textAbstract:
This study explored how the recovery of victims of sexual abuse is shaped by services available. Using the philosophical underpinnings of critical theory within the framework of Honneth's recognition theory this study provides an understanding of participants' experiences and views of recovery from sexual abuse. The study was conducted with ten adult survivors of sexual abuse using semi-structured individual interviews and two focus groups with eight service providers. The analysis identified that the recovery from sexual abuse is the development of a positive sense of identity reflected by participants' self-confidence, self-respect, and self-esteem. In this study this is described as the process of identity formation. Services shaped recovery from sexual abuse by providing experiences of recognition and disrespect. Recognition was given in the form of emotional support and care, cognitive respect, and social esteem that led to an improvement of participants' functioning. Disrespect was perceived by participants as they struggled with the invisibility of sexual abuse, with inequality, and with the lack of understanding, through which their overall functioning deteriorated. Recovery emerged as a dynamic process that, most of all, required from services that they provide experiences of recognition and from survivors that they accurately perceive that recognition was given to them. For recovery to occur, participants needed to balance experiences of recognition and disrespect, a process in which they needed to surrender the longing for the entirely good and benign caregiver and accept that both 'good' and 'bad' qualities reside in each caregiver, agency, therapist, or generally the 'other'. This balancing resulted in the development of self-confidence, self-respect, and self-esteem. Recovery was experienced by participants when they were able to resist disrespect and either engaged in fighting for their rights or removing themselves from situations in which their rights could be violated. Only by having a practical experience of being able to protect their physical and psychological integrity did participants become aware that they had recovered from the legacies of sexual abuse and could proceed with their lives without professional assistance.

Plowman, Suzanne F. "Self-Esteem as a Predictor of Treatment Outcome Among Women with Eating Disorders." BYU ScholarsArchive, 2007. https://scholarsarchive.byu.edu/etd/1005.
Full textAbstract:
Current empirical evidence suggests that true recovery from eating disorders is not possible without a corresponding improvement in body image and self-esteem. Ten studies in current literature evaluate this relationship between self-esteem and clinical eating disorders during inpatient treatment or during follow-up studies but do not provide both pre- (baseline) and post-treatment self-esteem scores. As a result, many questions about the nature of the relationship between eating disorders and self-esteem remain unanswered. The purpose of this study was to empirically investigate whether a comprehensive measure of self-esteem, given to women at the beginning of inpatient treatment for eating disorders, reliably predicted treatment outcome. Specific and global levels of self-esteem were determined by the Multidimensional Self-Esteem Inventory (MSEI). Pearson Product Moment Correlations run on SPSS 10 were used to determine significant results. Participants in this study included 246 women experiencing anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified who received inpatient treatment at the Center for Change (CFC), in Orem, Utah, during the years 1996 to 2003. For the purposes of this study, outcome was measured upon termination of treatment at the Center for Change. CFC discharge was based on clinical judgment of progression through the treatment program, medical stability, reduction of purging behaviors, body weight, as well as attainment of additional treatment goals designed by the therapist. The results of the current study replicate earlier research that reports that positive treatment outcome is nearly always associated with high self-esteem at discharge. These findings extend earlier research by suggesting that high levels of self-esteem at admission are associated with positive treatment outcome. This investigation, which is the first to examine self-esteem change scores between admission and discharge, found that women who experience the greatest decrease in eating disorder symptomatology are those who presented at admission with low self-esteem. Further, a significant association was found between improvements in self-esteem and decreases in eating disorder symptomatology. These findings suggest that the women who report high self-esteem at admission, or women who have low self-esteem but make dramatic improvements by discharge, are likely to experience significant reductions in disordered eating behaviors.

Mizar, Shivananda Pai. "Thermomechanical characterization of NiTiNOL and NiTiNOL based structures using ACES methodology." Digital WPI, 2006. https://digitalcommons.wpi.edu/etd-dissertations/61.
Full textAbstract:
Recent advances in materials engineering have given rise to a new class of materials known as active materials. These materials when used appropriately can aid in development of smart structural systems. Smart structural systems are adaptive in nature and can be utilized in applications that are subject to time varying loads such as aircraft wings, structures exposed to earthquakes, electrical interconnections, biomedical applications, and many more. Materials such as piezoelectric crystals, electrorheological fluids, and shape memory alloys (SMAs) constitute some of the active materials that have the innate ability to response to a load by either changing phase (e.g., liquid to solid), and recovering deformation. Active materials when combined with conventional materials (passive materials) such as polymers, stainless steel, and aluminum, can result in the development of smart structural systems (SSS). This Dissertation focuses on characterization of SMAs and structures that incorporate SMAs. This characterization is based on a hybrid analytical, computational, and experimental solutions (ACES) methodology. SMAs have a unique ability to recover extensive amounts of deformation (up to 8% strain). NiTiNOL (NOL: Naval Ordinance Lab) is the most commonly used commercially available SMA and is used in this Dissertation. NiTiNOL undergoes a solid-solid phase transformation from a low temperature phase (Martensite) to a high temperature phase (Austenite). This phase transformation is complete at a critical temperature known as the transformation temperature (TT). The low temperature phase is softer than the high temperature phase (Martensite is four times softer than Austenite). In this Dissertation, use of NiTiNOL in representative engineering applications is investigated. Today, the NiTiNOL is either in ribbon form (rectangular in cross-section) or thin sheets. In this Dissertation, NiTiNOL is embedded in parent materials, and the effect of incorporating the SMA on the dynamic behavior of the composite are studied. In addition, dynamics of thin sheet SMA is also investigated. The characterization is conducted using state-of-the- art (SOTA) ACES methodology. The ACES methodology facilitates obtaining an optimal solution that may otherwise be difficult, or even impossible, to obtain using only either an analytical, or a computational, or an experimental solution alone. For analytical solutions energy based methods are used. For computational solutions finite element method (FEM) are used. For experimental solutions time-average optoelectronic holography (OEH) and stroboscopic interferometry (SI) are used. The major contributions of this Dissertation are: 1. Temperature dependent material properties (e.g., modulus of elasticity) of NiTiNOL based on OEH measurements. 2. Thermomechanical response of representative composite materials that incorporate NiTiNOL“fibers". The Dissertation focuses on thermomechanical characterization of NiTiNOL and representative structures based on NiTiNOL; this type of an evaluation is essential in gainfully employing these materials in engineering designs.

Titre : Nano-plaquettes à mobilité dirigée et adhésion amplifiée pour l’administration locale: vers un nouveau traitement des maladies vésicalesAbstract : L’administration locale des médicaments, définie comme une voie d’administration où la substance active est directement administrée sur ou proche de la cible ou tissus souhaités, permet d’apporter des grandes quantités des médicaments avec moins d’effets secondaires, et permet une simplification du système nanoparticulaire du fait de la non-extravasation des médicaments. Dans ce contexte, le projet de recherche de cette thèse s’est focalisé sur la voie intra-vésicale comme voie d’administration locale car il existe un besoin clinique de la part des patients, n’étant pas encore résolu. Malgré les hypothétiques avantages fournis par l’administration locale des médicaments, la voie intra-vésicale présente certaines limitations qui diminuent l’efficacité des traitements et l’observance des patients. La plupart des médicaments pour le traitement des maladies vésicales, notamment pour le cancer de la vessie et les cystites interstitielles, sont sous forme de solutions ou suspensions administrées de manière intra-vésicale via un cathéter qui passe à travers l’urètre. Dès leur arrivée à la vessie, les substances actives sont fortement diluées par les urines et éliminées rapidement lors de la miction. Cela conduit à une diminution des concentrations des substances actives au plus proche de l’épithélium, nécessitant plusieurs instillations intra-vésicales, réalisées par des praticiens hospitaliers, pour atteindre des concentrations thérapeutiques. Il y a donc un réel besoin de développer des nouvelles formulations permettant de contrecarrer les phénomènes décrits au préalable.L’objectif de cette thèse de doctorat est de créer un nouveau système nanoparticulaire de morphologie non-sphérique qui serait susceptible d’avoir un mouvement diffèrent et dirigé ainsi qu’une adhésion amplifiée. En conséquence, nous attendons de ces systèmes qu’ils apportent des concentrations en substances actives plus importantes que les systèmes nanoparticulaires sphériques et formulations galéniques traditionnelles.Aux cours de nos travaux expérimentaux, nous avons réussi à développer un système nanoparticulaire de morphologie hexagonale et aplatie. Ces nanoparticules, appellées nano-plaquettes, sont conçues à partir de l’auto-assemblage des molécules d’α-CD et des chaines alkyles greffées sur les squelettes de polysaccharides tels que l’acide hyaluronique, la chondroïtine sulfate ou l’héparine. Ces systèmes présentent l’originalité de ne pas avoir de substance active encapsulé parce que les molécules de polymère elles mêmes agissent à la fois en tant que substance active et de véhicule. Ces nano-plaquettes ont montré un mouvement en milieu isotrope et statique très diffèrent des nano-sphères utilisées comme contrôle. En effet, la majorité d’entre elles diffuse de manière plus importante et dirigée, avec des trajectoires rectilignes. Grâce à leur mouvement et aux propriétés inhérentes liées à leur forme, ces systèmes se sont montrés particulièrement intéressants vis-à-vis des interactions avec des cellules. Ils adhèrent mieux et plus longtemps à la muqueuse vésicale, elles sont mieux internalisées par des cellules et sont éliminées plus lentement une fois adhérées à la surface de l’urothélium.Un modelé in vivo de Syndrome de la Vessie Douloureuse / Cystite Interstitielle développé chez le rat nous a permis de montrer l’efficacité thérapeutique des nano-plaquettes, notamment celle constituées d’acide hyaluronique. En effet, elles présentent une meilleure bioaccumulation dans la vessie et une meilleure activité anti-inflammatoire et de régénération de la muqueuse urothéliale.Ces systèmes nanoparticulaires, conçues lors de nos travaux de thèse, constituent une approche innovante, rationnelle et efficace pouvant ouvrir de nouvelles voies de recherche pour le traitement des maladies vésicalesTitle: Directed-mobility and enhanced-adhesion nano-platelets for local drug delivery: towards a new treatment of bladder diseases.Abstract: Local drug delivery, defined as the administration route where the drug is delivered directly or very close to its target or tissue, allows to bring large amounts of drugs with reduced side effects, in comparison with systemic administration. In this context, our research project has been focused on the intravesical drug delivery as local administration route, because there is a real need to develop new pharmaceutical formulations to thwart several limitations. Despite the advantages provided by the local drug delivery, intravesical drug delivery exhibited some issues which are decreasing the therapeutic efficacy and the patient compliance to the treatment. Most of therapies for the treatment of bladder diseases are simple drug solutions or suspensions administered intravesically by using a catheter through the urethra in order to reach easily the bladder and, consequently, the urothelium. Since the drug is administered into the bladder, drug dilution is occurring because the continuous production of urine. Furthermore, active substances are being eliminated during washout when bladder urine voiding is happening. These two processes lead to the decrease of local drug concentration close to the urothelium. Patients need repeated catheterization, performed by health care practitioners, to reach therapeutic dose of the drug. Therefor, there is a need of new drug formulations to avoid these main limitations.The main goal of this PhD thesis was to create and design a new nanoparticulate system with non-spherical shape susceptible to move in a different manner compared to spherical nanoparticles. These systems may exhibit an amplified mucoadhesion allowing to bring more important amounts of drug than classical and nanoparticle administration.During this thesis, we developed a new nanoparticulate system presenting non-spherical, hexagonal and flattened shape. The driven force for the design of these nanoparticles was the self-assembling of α-cyclodextrin molecules with alkyl chains grafted on the polymer skeleton. Polymers used belong to a polysaccharide family called glycosaminoglycans including hyaluronic acid, chondroitin sulfate or heparin. This original and innovative nanoparticulate system does not encapsulate an active drug. Our polysaccharide will act, at the same time, as the active drug and the carrier. These nanoparticles, called now nano-platelets have shown different movement behavior than the spherical ones. Indeed, they diffuse more rapidly in a straight-line way. Thanks to their oriented and directed motion and to their intrinsic properties, due to the shape, these systems have shown a better mucoadhesion on the bladder tissue, a better uptake in different cell lines and they were far less rapidly eliminated from the urothelium mucosa.An in vivo model of Bladder Painful Syndrome / Interstitial Cystitis in rats demonstrated the therapeutic efficacy of nano-platelets, especially for hyaluronic acid nanoparticles. Indeed, they demonstrated a better bioaccumulation into the bladder and a better therapeutic efficacy as anti-inflammatory and urothelium regenerating agents.These nanoparticulate systems, designed during this work, represent a new innovative, rational and effectiveness approach allowing to open new research pathways for the treatment of bladder diseases

Saedi, Soheil. "Shape Memory Behavior of Dense and Porous NiTi Alloys Fabricated by Selective Laser Melting." UKnowledge, 2017. http://uknowledge.uky.edu/me_etds/90.
Full textAbstract:
Selective Laser Melting (SLM) of Additive Manufacturing is an attractive fabrication method that employs CAD data to selectively melt the metal powder layer by layer via a laser beam and produce a 3D part. This method not only opens a new window in overcoming traditional NiTi fabrication problems but also for producing porous or complex shaped structures. The combination of SLM fabrication advantages with the unique properties of NiTi alloys, such as shape memory effect, superelasticity, high ductility, work output, corrosion, biocompatibility, etc. makes SLM NiTi alloys extremely promising for numerous applications.
The SLM process parameters such as laser power, scanning speed, spacing, and strategy used during the fabrication are determinant factors in composition, microstructural features and functional properties of the SLM NiTi alloy. Therefore, a comprehensive and systematic study has been conducted over Ni50.8 Ti49.2 (at%) alloy to understand the influence of each parameter individually. It was found that a sharp [001] texture is formed as a result of SLM fabrication which leads to improvements in the superelastic response of the alloy. It was perceived that transformation temperatures, microstructure, hardness, the intensity of formed texture and the correlated thermo-mechanical response are changed substantially with alteration of each parameter. The provided knowledge will allow choosing optimized parameters for tailoring the functional features of SLM fabricated NiTi alloys. Without going through any heat treatments, 5.77% superelasticity with more than 95% recovery ratio was obtained in as-fabricated condition only with the selection of right process parameters.
Additionally, thermal treatments can be utilized to form precipitates in Ni-rich SLM NiTi alloys fabricated by low energy density. Precipitation could significantly alter the matrix composition, transformation temperatures and strain, critical stress for transformation, and shape memory response of the alloy. Therefore, a systematic aging study has been performed to reveal the effects of aging time and temperature. It was found that although SLM fabricated samples show lower strength than the initial ingot, heat treatments can be employed to make significant improvements in shape memory response of SLM NiTi. Up to 5.5% superelastic response and perfect shape memory effect at stress levels up to 500 MPa was observed in solutionized Ni-rich SLM NiTi after 18h aging at 350ºC. For practical application, transformation temperatures were even adjusted without solution annealing and superelastic response of 5.5% was achieved at room temperature for 600C-1.5hr aged Ni-rich SLM NiTi.
The effect of porosity on strength and cyclic response of porous SLM Ni50.1 Ti49.9 (at%) were investigated for potential bone implant applications. It is shown that mechanical properties of samples such as elastic modulus, yield strength, and ductility of samples are highly porosity level and pore structure dependent. It is shown that it is feasible to decrease Young’s modulus of the SLM NiTi up to 86% by adding porosity to reduce the mismatch with that of a bone and still retain the shape memory response of SLM fabricated NiTi. The shape memory effect, as well as superelastic response of porous SLM Ni50.8Ti49.2,were also investigated at body temperature. 32 and 45% porous samples with similar behaviors, recovered 3.5% of 4% deformation at first cycle. The stabilized superelastic response was obtained after clicking experiments.

Full textAbstract:
Bakgrund: Anorexia Nervosa är en av den vanligaste ätstörningen och drabbar främst yngre kvinnor. Sjukdomen leder till en förvrängd kroppsuppfattning och karaktäriseras främst av viljestyrd överdriven bantning. Långvarig och grav AN kan skada kroppens organ vilket kan vara livshotande. AN är den psykiatriska sjukdomen med högst dödslighetsgrad. Det är svårt att behandla patienter med AN då det finns ett motstånd från dessa patienter på grund av att de förnekar sina beteenden. Det kan även bero på stigman kring ätstörningar som finns i samhället, vilket leder till att patienter undviker eller uteblir från behandling. Syfte: Att beskriva unga kvinnors upplevelser av att leva med anorexia nervosa. Metod: En kvalitativ analys av narrativer tillämpades på sex bloggar från Google. Bloggarna var skrivna av kvinnor i åldrarna 16–26 år. Resultat: Ur analysen framträdde tre kategorier; Att skambelägga sig själv, Självhat och Begynnande sjukdomsinsikt med sju underkategorier. Konklusion: Studien kan leda till en ökad förståelse och kunskap kring patienters upplevelser av att leva med AN, vilket kan bidra till att sjuksköterskan kan utföra en mer personcentrerad vård.Background: Anorexia Nervosa is one of the most common eating disorders and mainly affects younger women. The disease leads to a distorted body image and is characterized mainly by will-driven excessive dieting. Prolonged and severe AN can damage the body's organs which can be life-threatening. AN is a psychiatric disease with a high risk of death. It is difficult to treat patients with AN because there is resistance from these patients though they are in complete deny of their behaviour. It may also be due to the stigma surrounding eating disorders that exist in the community, which leads to patients avoiding treatments for their disease. Purpose: To describe young women's experiences of living with anorexia nervosa. Method: A qualitative analysis of narratives was applied to six blogs from Google. The blogs were written by women aged 16-26 years. Results: Three categories emerged from the analysis; To shame oneself, Selfhatred and Incipient desease insight with seven subcategories. Conclusion: The study can lead to an increased understanding and knowledge of patients' experiences of living with AN, which can help the nurse to provide a good person-centered care.

Full textAbstract:
Många människor har efter avslutad psykoterapi tankar om densamma. Kanske fanns det ämnen som inte kom att benämnas, eller om de överhuvudtaget benämndes kom att göra det i begränsad utsträckning. Uppsatsen bygger dels på en empiriskt genomförd undersökning och dels på litteraturstudier. Det är en kvalitativ studie med halvstrukturerade frågor och meningskoncentrering. Fem personer har intervjuats, minst sex månader har gått sedan psykoterapin avslutades. Syftet med studien är att undersöka de processer som utifrån ett patientperspektiv ligger bakom att visst material inte aktualiserats i psykoterapin. För att göra intervjumaterialet överskådligt delades det upp i två dimensioner. Den första dimensionen beskriver de faktorer som förorsakat den förändrade upplevelsen av terapin. Den andra dimensionen beskriver de processer som hindrar att viktigt material aktualiseras. Dessa hinder handlar dels om specifika hinder som har med den psykoterapeutiska relationen att göra och dels handlar det om hinder som har att göra med olika försvarsstrategier som patienten använt sig av under sin psykoterapi. Flera av personerna uttryckte efter avslutad terapi en besvikelse över att man i psykoterapin upplevde en brist på djup och att det var ämnen som man ibland undvikit att prata om. Det framkom att problem i samband med överföringen innebar svåra motstånd mot fördjupningen av psykoterapin. En viktig slutsats i studien var att man antingen tenderade att skuldbelägga sig själv för de svårigheter som uppstod i psykoterapin alternativt att man lade över huvudansvaret för svårigheterna på terapeuten. Skam var ett återkommande ämne i flera av intervjuerna. Hur arbetsalliansen fungerade visade sig vara helt avgörande för hur psykoterapin utvecklades.

Full textAbstract:
During the last 10 years, low pressure carburizing and high pressure gas quenching has become more popular since it is a “new” process and researchers reports that the distortion characteristics gained from these processes is improved in relation to conventional processes. The aim of this work was to investigate the distortions gained from three different heat treatment processes on main shaft gears and crown wheels. Experiments with atmospheric carburization with oil quenching and low pressure carburization with nitrogen gas quenching or oil quenching were made and distortion characteristics gained from these processes were then measured and compared. It was found that components treaded in the relatively new LPC-HPGQ process are similar and often even better than the conventional method. The larger main shaft gear improves the most with newer method but instead gets a lower core hardness and systematic diametrical shrinkage. Some measurements on the crown wheel were also improved but others were affected negatively.

Full textAbstract:
This research builds upon and explores an enigmatic set of experiences which theorists in the Object Relations tradition have characterised as regression to dependence, a return to a primitive, pre-verbal relational process presenting in some clients in psychotherapy. This research is a study of the concept of regression to dependence, its manifestation within the psychotherapy process, and facilitation within the therapeutic relationship. The Psychoanalytic theoretical positions on regression to dependence are explored, together with the Relational/Developmental perspective which recognises regression and its importance within psychotherapy. This exploration seeks to understand the experience of regression to dependence, how regression to dependence can be effectively worked within Integrative Psychotherapy, and makes recommendations for Integrative practitioners and theorists related to effective facilitation of clients, showing how the Relational/Developmental approach can effect repair. The study employs a qualitative methodology. A heuristic study was undertaken in which eleven practicing psychotherapists were interviewed and data was collected via semi-structured interviews. Most participants were interviewed twice, with a view to collecting data on both their personal experience as a client in psychotherapy and also their experiences as practitioners when working with clients who were experiencing regression to dependence. The transcripts from these interviews were analysed for emergent themes. The themes are discussed in the context of and with reference to the Psychoanalytic theoretical position and the Relational/Developmental perspective. An account is offered of how these experiences have come to be understood as recollecting difficulties in early infantile relationships. Reflections are made on the essence and qualities of a therapy that can facilitate regression to dependence in order to promote healing. Recommendations are made for the practice of Integrative Psychotherapy and the training of Integrative Psychotherapists in order to prepare them for this work. These recommendations for therapists include; having sufficient preparation, knowledge and understanding to be able to recognise and work with a regressive process emerging in the client; having an understanding of the need to facilitate this process for some clients; and to be aware of the need for particular adaptations in the therapeutic stance in some circumstances, and the difficulties which may arise. Recommendations are also offered regarding the support needed for the therapist whilst working with this process, which include the need for ongoing personal therapy, and supervision. The researcher’s personal story is an intrinsic part of the research, and as an integral part of this study is in accordance with the heuristic and autoethnographic styles, and with the practice of Integrative Psychotherapy, where the use of self is seen as a crucial clinical tool in the therapeutic process. Throughout this study reflexivity has been used regarding the personal experiences of the researcher as client, therapist and researcher.

Full textAbstract:
Background Opinion is divided with regards to the extent to which client disclosure in therapy advantages clients. Furthermore, inconsistent research findings suggest the ease with which an individual discloses is a function of multiple influences. Objectives To explore the relationship between client non-disclosure in therapy and current eating disorder (ED) symptoms in individuals who had received treatment for an EO. A second aim was to investigate factors facilitating and inhibiting client self- disclosure; in particular client shame, the therapeutic alliance, and therapist self- disclosure. Method Participants (n=120) completed an online survey comprising questionnaires and open-ended questions assessing ED symptoms, shame-proneness, non-disclosure in therapy, perceived therapist disclosure, and the therapeutic alliance. Results Shame and the therapeutic alliance were significantly related to current ED symptoms (r=.46 and r= -.19 respectively) and total client non-disclosure (r=.41 and r= -.43 respectively). Total client non-disclosure was significantly related to current ED symptoms (r=.31) and fully mediated the relationship between the therapeutic alliance and current ED symptoms. Client non-disclosure did not mediate the relationship between shame and current ED symptoms. Only therapist disclosure of 'negative feelings towards a client' was significantly related to client non-disclosure (r=.28). This relationship was partially mediated by the therapeutic alliance. Thematic analysis of open-ended questions revealed substantial variability across participants regarding the perceived helpfulness of therapist disclosure and the overall factors perceived to facilitate and inhibit client self-disclosure. Conclusions The hypothesised model whereby client non-disclosure mediated the relationship between the therapeutic alliance and current ED symptoms was supported. Furthermore, the therapeutic alliance partially mediated the relationship between therapist disclosure of negative feelings towards a client and client non- disclosure. Results suggest the strength of the therapeutic relationship, influenced by therapist disclosure, has important implications for a client's willingness to disclose and current ED symptoms.

Full textAbstract:
The ecological restoration of Peninsula Shale Renosterveld is essential to redress its conservation target shortfall. The ecosystem is Critically Endangered and, along with all other renosterveld types in the Cape lowlands, declared 'totally irreplaceable'. Further to conserving all extant remnants, ecological restoration is required to play a critical part in securing biodiversity and to meeting conservation targets. Remnants of Peninsula Shale Renosterveld are situated either side of the Cape Town city bowl and, despite formal protection, areas of the ecosystem are degraded and require restoration intervention. The body of research addressing restoration in renosterveld is small, yet growing, and seed-based restoration efforts have achieved limited success. This study primarily set out to further understand community recovery through determining the effects of interventions, implemented to mimic ecological drivers, on several seed germination criteria. Thirty-two interventions (comprised of five, crossed factors: burning, tillage, herbicide-application, rodent-exclusion and seeding) were incorporated into a field experiment situated in an area that was most likely ploughed over a century ago and is currently dominated by alien, annual grasses. Additional aspects of the study included determining the physiological status of the seed from 31 harvested species (through viability and germinability tests) towards identifying key restoration species, and, assessing intervention costeffectiveness as a measure of intervention feasibility. The majority of the harvested species exhibited moderate to high levels of viability and germinability and occurred in the middle or upper key-restoration-species index range, indicating their potential for use in future restoration efforts. Seeding contributed considerably to overall community attributes, significantly increasing indigenous seedling density, species richness and canopy cover. Due to the dominance of alien, annual grasses, seeding alone was relatively ineffectual and recruitment was considerably improved when seeding was implemented in conjunction with one or more of the other interventions. These findings indicate that a lack of available seed is not the only barrier to community recovery and that competition exerted by the alien grass component plays a large role in inhibiting seedling recruitment of desirable species. Intervention effectiveness increased with the number of factors per intervention yet, fortuitously, the most effective interventions were not necessarily the most costly. Some interventions resulted in good performances and have the potential to restore self-perpetuating communities with a semblance of ecosystem composition, structure and function. There is a clear and promising way forward incorporating these findings into feasible, implementable, landscape-scale, ecological restoration strategies for Peninsula Shale Renosterveld and potentially other Critically Endangered and 'totally irreplaceable' renosterveld ecosystems.

Full textAbstract:
Laser metal deposition (LMD) offers a unique combination of process flexibility, time savings, and reduced cost in producing titanium alloy components. The current challenge in processing titanium alloys using LMD methods is understanding the complex microstructure evolution as a part is fabricated layer by layer. The current work focuses on the characterization, thermal, and microstructural modeling of multilayered Ti-6Al-4V deposits. A thermal model has been developed using finite difference techniques to predict the thermal history of LMD processes. A microstructure model that predicts the alpha phase fraction and morphology evolution was constructed to quantify the effect of thermal cycling on the as-deposited microstructure evolution. Alpha dissolution and growth are modeled assuming one-dimensional plate dissolution according to a parabolic rate law, and a Johnson-Mehl-Avrami-Kolmorgorov (JMAK) nucleation and growth model, respectively. Alpha morphology (colony-alpha and basketweave-alpha) evolution is tracked using a simplistic approach.
Characterization of the deposit has shown that a complex microstructure evolves consisting of a two distinct regions: a transient region of undeveloped microstructure and a characteristic layer that is periodically repeated throughout the deposit. The transient region contains a fine basketweave and colony-alpha morphology. The characteristic layer contains a two phase mixture of alpha+beta, with the alpha phase exhibits regions of colony-alpha (layer band) and basketweave-alpha morphology.
The different regions of microstructural contrast in the deposit are associated with thermal cycling. The thermal model results show that a heat affected zone defined by the beta transus extends approximately 3 layers into the deposit. The phase fraction model predicts the greatest variation in microstructural evolution to occur in a layer n after the deposition of layer n+3. The results of the morphology model show that increased amounts of colony-alpha form near the top of a characteristic layer. It follows that a layer band (colony-alpha region) forms as a result of heating a region of material to a peak temperature just below the beta transus, where a large amount of primary-alpha dissolves. Upon cooling, colony-alpha forms intragranularly. The coupled thermal and microstructure models offer a way to quantitatively map microstructure during LMD processing of Ti-6Al-4V.Ph. D.

Full textAbstract:
Hoarding disorder is a mental illness that affects about 2-5 % of the population. The most prominent symptoms of hoarding disorder are the inability to discard things and the excessive acquisition of possessions. The home becomes cluttered, often to the point where one no longer can use the rooms for their intended purposes. For example, one can no longer sleep in the bed or use the kitchen for cooking because of the clutter that takes up space. People with hoarding disorder often experience shame because of their disability and as a consequence they withdraw from social engagements and risk isolation. The purpose of this study was to give a literary review of treatment methods for hoarding disorder and their efficacy in Swedish, but also to show the impact of shame on treatment effect through Thomas Scheff’s theory of shame. The primary treatment method is Cognitive behavioral therapy designed especially for hoarding disorder, and has been tested in different forms such as individual-, group-, and internet based treatment. New treatments using Compassion-focused therapy and Acceptance and commitment therapy have also been developed. Studies on hoarding disorder and shame have shown a correlation between shame, symptom severity and identity. These new treatments address the shame experienced and they can hopefully increase the efficacy rate for hoarding treatment. Important factors for treatment progress were, among others, continued high motivation, frequent contact with clinician and a supportive family. A surprising result was that one study showed almost equal result in treatment led by a non-professional as a professional. More research is needed to further develop effective treatment.

I denna uppsats beskrivs situationen för mångbesökarna inom missbruks- och beroendevården. Kvalitativt intervjumaterial belyser upplevelser och erfarenheter som rör deras beroendeproblematik. De bär alla på någon form av samsjuklighet och återkommer till psykiatriska intensiv- och akutmottagningen för avgiftning på sjukhus. Att hitta sätt att avlasta den mentala smärtan är ledande genom berättelserna tillsammans med uttalade behov av att bli lyssnade på och av att bli tagna på allvar. Genom makt att påverka sin situation och kraft att förändra den i gemenskap med andra kan de lindra sin ohälsa. Pendlingen mellan nedbrytning och uppbyggnad tär på både kropp och själ, samtidigt som vården de erhåller gör att de känner sig fångade i ett ekorrhjul. Att fokusera på självuppfattning kan leda till banbrytande förändringsmöjligheter och återuppbyggnad genom att ta hänsyn till hela människans potential. Teorier kring emotionell energi, skam och stolthet förklarar hur detta är möjligt.In this study the situation for frequent attenders at substance abuse and addiction carefacilities is described. Qualitative interview data illustrates their experiences related to substance abuse. They all carry some form of co-morbidity and recurrence of psychiatric intensive care with detoxification in hospital. Finding ways to relieve mental illness is ever present in their narratives, along with the expressed needs to be listened to and to be taken seriously. The power to influence their situation and the power to change it in community with others, can relieve their illness. Commuting between formation and degradation depletes body and soul, while the care they receive makes them feel like they are caught in a ratrace. Focusing on selfperception could lead to groundbreaking opportunities for change and reconstruction by taking into account their full human potential. Theories of emotional energy, shame and pride explains how this is possible.
