Higgins, Jolie. "Carbonate Chemistry Characterization in a Low-Inflow Estuary With Recent Seagrass Loss." DigitalCommons@CalPoly, 2019. https://digitalcommons.calpoly.edu/theses/2053.
Full textAbstract:
Estuaries are dynamic environments that are strongly affected by natural variability, as well as direct and indirect anthropogenic impacts. A better understanding of the drivers of carbon fluxes and biogeochemical variability in estuarine systems is needed, particularly with the increasing threat of ocean acidification. Morro Bay in Central California is a small nationally protected estuary, with seasonally low freshwater inputs. Since 2007, the bay has experienced a significant loss of native seagrass, Zostera marina, which is an important component of the marine ecosystem. Because seagrass photosynthesis decreases carbon dioxide and increases oxygen in the water column, the loss of seagrass has the potential to substantially change short-term carbonate chemistry and long-term carbon fluxes of an estuary. The spatial variability of carbonate chemistry was measured in Morro Bay using ship-board surveys during the low-inflow summer season and measured the temporal variability by collecting samples close to the shore from July to November. Discrete samples show an increase in total alkalinity and dissolved inorganic carbon in the mid and back bay regions, historically dominated by seagrass. Slightly lower total alkalinity and dissolved inorganic carbon were observed in the Fall season compared to the low-inflow Summer season. Analysis of the relative modification of alkalinity and dissolved inorganic carbon, paired with salinity and temperature data, contributes to an understanding of the drivers of the observed carbonate variability. This understanding may provide clues to the causes and effects of observed changes to the bay with seagrass loss. More broadly, it will inform the vulnerability of other low-inflow estuaries to future acidification and highlight the role seagrasses play in mitigating local acidification.

Hrevuš, Jan. "Non-Life Excess of Loss Reinsurance Pricing." Doctoral thesis, Vysoká škola ekonomická v Praze, 2010. http://www.nusl.cz/ntk/nusl-200014.
Full textAbstract:
Probably the most frequently used definition of reinsurance is insurance for insurance companies, by reinsurance the cedant (insurance company) cedes part of the risk to the reinsurer. Reinsurance plays nowadays a crucial role in insurance industry as it does not only reduce the reinsured's exposure, but it can also significantly reduce the required solvency capital. In past few decades various approaches to reinsurance actuarial modelling were published and many actuaries are nowadays just reinsurance specialized. The thesis provides an overview of the actuarial aspects of modelling a non-life per risk and for motor third party liability per event excess of loss reinsurance structure, according to the author's knowledge no study of such wide scope exists and various aspects have to be found in various fragmented articles published worldwide. The thesis is based on recent industry literature describing latest trends and methodologies used, the theory is compared with the praxis as the author has working experience from underwriting at CEE reinsurer and actuarial reinsurance modelling at global reinsurance broker. The sequence of topics which are dealt corresponds to sequence of the steps taken by actuary modelling reinsurance and each step is discussed in detail. Starting with data preparation and besides loss inflation, more individual claims development methods are introduced and own probabilistic model is constructed. Further, burning cost analysis and probabilistic rating focused on heavy tailed distributions are discussed. A special attention is given to exposure rating which is not commonly known discipline among actuaries outside of reinsurance industry and different methodologies for property and casualty exposure modelling are introduced including many best practice suggestions. All main approaches to the reinsurance modelling are also illustrated on either real or realistically looking data, similar to those provided by European insurance companies to their reinsurers during renewal periods.

McClelland, Duane Michael. "Estimating Life Loss for Dam Safety Risk Assessment." DigitalCommons@USU, 2000. https://digitalcommons.usu.edu/etd/4553.
Full textAbstract:
" Estimating Life Loss for Dam Safety Risk Assessment" explores the need for a new life-loss model in dam safety risk assessment, historical foundations on which that model can be built, and issues that are critical for a successful life-loss model to address. After critiquing existing life-loss models, the work presents a summary of historical insights that were derived by characterizing flood events on the level of subpopulations at risk, using nearly l 00 carefully defined variables. Building upon both conceptual and historical insights, the work culminates by presenting the conceptual basis for a new life-loss model that remains under development.
Chapter I introduces the topic of dam safety risk assessment and the central role that life-loss estimation plays in that field. Chapter II discusses important preliminary considerations in model development. Chapter Ill provides a detailed review of previous life-loss models that pertained to floods, including a critique of each. Chapter IV explores the DeKay-McClelland model in detail and raises serious concerns regarding its future use. Chapter V defines nearly l 00 variables and their respective categories for use in characterizing flood events. Chapter VI provides a detailed outline of historical insights that relate to flood events in one of 18 logical categories. Chapter VII proposes the framework for a new conceptual life-loss model-a model that is still under development and has yet to be refined or offered for testing-with sufficient details to indicate how it was developed and how it might be used. Chapter VIII provides a summary, conclusions, and recommendations for future research. Appendices A through D provide material related to over 900 pages of unpublished working documents developed while characterizing 38 flood events and nearly 200 subpopulations at risk. Appendix E offers a summary of existing software that, given additional development, might prove useful to life-loss estimation in dam safety risk assessment.

Full textAbstract:
Normative ideas of age and stage-based transitions are built into policies and practices related to aging. However, how the issues of loss and depression impact older people's experiences of transition are often less prevalent. This paper discusses the sub-theme of loss identified within data from the Late Life Transitions Project; a SSHRC funded research project. In this thesis, qualitative interviews were analyzed from 30 community-residing seniors from diverse social backgrounds. Focused exploration of the everyday ways in which older people discussed major transitions and turning points revealed a strong subtheme of loss. Findings presented are related to the types of loss, the various barriers to integrating loss, coping mechanisms and the impact of social location on loss. Such discussions inform understandings of the ways in which older people discuss and make sense of their loss, and may provide guidance to plan interventions that are more relevant to older people's late life experiences.

Aboelata, Maged A. "Conceptualization and Development of a Dam Break Life-Loss Estimation Model." DigitalCommons@USU, 2005. https://digitalcommons.usu.edu/etd/4540.
Full textAbstract:
Catastrophic events such as dam failures or severe floods are considered to be of low probability, although their consequences can be extremely high and might include loss of life. Earlier studies have linked circumstances surrounding historical darn failure events to actual loss of life and produced formulations using statistical analysis of these events. Shortcomings of these methods include the inability to adjust life-loss estimates based on the type of darn failure, global averaging of population at risk, and ignoring the dynamics of the evacuation process.
The main objective of this research is to develop a practical and improved life-loss estimation approach for use in dam safety risk assessment and emergency planning. The methodology is specifically formulated to overcome the limitations of previous. purely empirical, approaches. The approach takes into account the spatial and temporal distribution of flood water depth and velocity, fate of buildings, simulation of warning diffusion, and tracking the movement of people from their original location towards safe shelters.
The model created, called LlFESim, is designed to serve multiple function s. First, it can be used in a Deterministic Mode using best estimate inputs to obtain point estimates, or to test different policies for evacuation as well as different times of the day and for different dam breach flooding scenarios. Second, the Uncertainty Mode represents input and parameter uncertainties to provide estimates of life loss, and other variables relating to warning and evacuation effectiveness, as probability distributions. These distributions of life loss can be combined with estimates of the uncertainties in other risk assessment inputs, to obtain estimates of uncertainties in risk assessment results, including evaluations against tolerable risk guidelines.
Two communities were used to demonstrate the model performance. Deterministic Mode results display the various possible model outputs. Sensitivity analysis for the Deterministic Mode shows that the effect of warning issuance time is the dominant factor in the estimated life loss. However, other factors play an important role such as the time of day, effectiveness of the warning system, and shelter location. Uncertainty Mode results demonstrate the effect of uncertainties in model parameters and inputs on the model results.

Epiphaniou, Eleni. "Life triggers, sustaining mechanisms and successful weight loss : how are they related?" Thesis, University of Surrey, 2008. http://epubs.surrey.ac.uk/842818/.
Full textAbstract:
Although the majority of obese and overweight individuals successfully lose weight only a minority maintain weight loss in the long term. This thesis, through a mixed model methods approach, examined the factors which reinforced healthy behavior change in a group of obese and overweight individuals and assessed the factors which underlined sustained behavior change in the minority of individuals who successfully maintained at least 10% of their initial weight loss. In particular, the thesis focuses on the role of life events in triggering behaviour change and the impact of sustaining conditions in maintaining this change in the long term. Study 1 was a quantitative study. Members of a commercial weight loss program (N= 1093) were invited to participate in the study through an online advertisement. The aim of the study was to examine participants' different weight patterns, based on their weight history, and to assess whether these patterns were explained by participants' weight and demographic characteristics. The results showed that weight histories could be categorized into 5 independent patterns which were: a) weight cycling with overall increase, b) weight cycling with initial weight stability, c) weight cycling with return to baseline, d) weight loss and e) gradual gain. Concerning participants' demographic and weight characteristics, results also revealed significant .differences between the different weight patterns. In addition, obese and overweight individuals indicated significant differences in their weight histories. Based on their weight histories, and in particular, their percentage of weight loss, participants could be also categorized into those individuals who regained some or all of their weight loss (unsuccessful participants; N= 592) and those who managed to maintain at least 10% of their initial weight loss and which they maintained for a minimum of one year (successful participants; TV = 431). Study 2 then focused on these two groups and aimed to examine the role of life events and sustaining conditions in behavior change and behavior maintenance. Variables such as participants' health status and experiences with consultants were also included in the analysis. Results revealed significant differences between the two groups with successful participants indicating more life events, less benefits from their unhealthy behavior, more choice over their healthy behavior and more psychological beliefs about causality which were related to their behavioral solutions. Also, successful participants were more positive concerning their health status and experiences with their consultants. Study 3 applied a within subjects design which aimed to examine the differences within the successful group between Time 1 (Their heaviest) and Time 2 (sustained weight loss) in regards to their health status and sustaining conditions of disruption of function, reduction choice and solutions for their increased weight. The results showed that maintaining weight loss was linked to an improved health status, more choice and perceived benefits over the healthy behavior and an endorsement of an improved and healthier lifestyle. Study 4, using a qualitative approach, aimed to further explore whether maintenance of behavior was related not only to the sustaining mechanisms but also to a shift in identity and perception of self. 10 successful individuals were invited to participate. Using IPA results indicated that weight loss maintenance is related to an identity shift from a previously restrained individual towards a liberated person who tends to redefine themselves based on new qualities apart from their weight. Overall, this thesis indicates that the minority of individuals who are finally successful in losing and maintaining weight loss are more likely to experience some life events central to their goals and identity. These events enhance maintenance when they are accompanied by sustaining mechanisms and by a shift in mental representations about their self.

Life with Birds is an investigation of the disjunction between public and private experiences of the Vietnam war and its aftermath. The creative non-fiction component of the thesis juxtaposes historical documents with family stories, photographs and memories in order to situate military history in the home and disrupt the binaries around dominant war tropes, such as the heroic/traumatic binary. It focuses on the everyday, the small scale and the ordinary as worthy of historical and cultural attention and aims to redress the silences and erasures in bureaucracies, archives and within families by reimagining or repopulating them with found materials, a combination of information, observation and guesswork. This lyric methodology was developed using concepts of Toni Morrison’s ‘literary archaeology’, Marianne Hirsch’s ‘postmemory’ and Hélène Cixous’ l’écriture féminine, as well as Claudia Rankine’s deployment of the lyric form in Citizen.
The exegesis examines writings and discourses around war in Australia that erase the experiences and legacy of certain war veterans and their families, including mine. In it I discuss the disconnect between national mythologisation and commemoration of Anzac and Vietnam veterans and the lived experiences of veteran families, such as impacts of war trauma, bureaucratic intransigence and veteran health and suicide. This thesis highlights the ongoing negotiations between public and private lives in an attempt to broaden the conversation around the invisible or erased impacts of war in Australia, particularly for women and the children of war veterans.

Full textAbstract:
This thesis critically examines the lived effects of economic restructuring in the city of Lençóis, Bahia, Brazil. Established at height of the region’s diamond mining boom in the mid 19th century, the local economy now rests almost exclusively on ecological tourism, with the city of Lençóis serving as the principal gateway to the Chapada Diamantina National Park. Combining ethnographic research methods, archive work and the analysis of governmental programs, I consider the impacts of tourism development strategies and conservation interventions on the lives and subjectivities of local community members. As it gives rise to new projects and new demands, I explore how this shift in political economy has interacted with historical processes of social and economic exclusion, and consider its role in reshaping uses and understandings of the material landscape. Yet, in foregrounding local responses to state-led projects for development, this thesis is also concerned with possibilities for contestation and critique. In Lençóis, memories of past modes of existence continue to evoke emotional resonance for many local people, and in particular local men. Exploring the stories people told me of their past lives and present-day experiences, I consider the affective dimensions of economic change, reading attachment to loss for its productive and creative potential (Eng and Kazanjian, 2003). These alternative narratives, voiced from the perspective of those most deeply affected by economic transition, reveal critical engagement with dominant cultural and political imperatives, and indicate how, in the midst of uncertainty, local people are responding to and seeking to challenge changes to the material circumstances of their lives.

Full textAbstract:
Approximately 15 % of Swedish people experience tinnitus, but only 2.4 % of them experience severe problems. Treatment modalities for tinnitus are varied, but the most common treatment model is counselling. The majority of patients with tinnitus report some degree of hearing loss, and in addition, hearing aids have been used for many years in patients who suffer from both tinnitus and hearing impairment. The aim of the present thesis was to investigate the disease management and identify the quality of life in patients with tinnitus and sensorineural hearing loss. Both studies described here are retrospective, descriptive studies of patients who sought care for tinnitus and hearing loss at the two ENT clinics in Östergötland County, Sweden, during 2004 - 2007 and who also received a diagnosis code. A medical record review of all patients (study I contained 1672 subjects) revealed that 714 patients were diagnosed with both tinnitus and SNHL between 2004 and 2007 and could be included in study II. The results showed that 70% of our cohort had tinnitus, but many of the patients initially did not receive a diagnosis for their tinnitus. Information about the patients’ vertigo, heredity for hearing loss and tinnitus, diabetes history, cardiovascular disease history and other factors related to their health was often missing from the medical records. Our findings showed that the Stepped Care Model, which however was only used in a minority of the cases, could be effective in patients with tinnitus and could provide a better care process for these patients. Of the cohort, 56% of the patients received a diagnosis of bilateral hearing loss. The pure tone average (PTA) of the left ear was significantly higher than that of the right ear. There were 314 patients (44%) who had hearing aids out of the total of 714, even though it is likely that hearing aids could be beneficial for these patients. We found that the overall scores for the Tinnitus Handicap Inventory (THI) were higher in female patients than male patients. All patients who participated in study II estimated their life quality and general health at a good level. This could be due to the fact that they were investigated 4.5 years after they first reported their tinnitus and that tinnitus annoyance decrease over time. Further, the outcomes of study II demonstrated that the majority of patients, who were dissatisfied with the care they obtained, had no hearing aids. This could indicate a support the use of hearing aids fitting as main treatment model in patients with both tinnitus and hearing loss. Future research is needed to investigate how hearing aid professionals could motivate patients who suffer from both tinnitus and hearing loss to use hearing aids.

De este modo, las entrevistas iniciales se convierten en relatos de devolución que culminan en un relato polifónico final. El proceso de investigación muestra pues, ya no solo un “nuevo modo” de investigar y evaluar; sino, que posibilita que se investigue “para”, “en” y “con” el museo, proporcionando a los participantes de la investigación espacios de reflexión para repensar, aprender y transformar su práctica profesional.
The current investigation is aimed at offering a methodological proposal to evaluate the 2.0 websites for group-interaction and social collective creation of the museums participating. These new logics of interaction, conversation and online communities constitution encorauge us to create these new museum contexts as discursive spaces and institutional practices that require a way of investigation that allows to know their process of creation and management. The biographical and narrative research with the life history as a methodological tool allows us to respond through the analysis of the experiences and speeches of the members of the participating museums. This is how the initial interviews become storytelling that culminate in a final polyphonic story. Consequently, the research process shows not only a "new way" of research and evaluating; but, that makes it possible to investigate “for”, “in” and “with” the museum, providing research participants a reflexive space to rethink and learn around their professional practice.

Full textAbstract:
The prevalence of overweight and obesity in the feline population is estimated to be 25.7% and 33.8%, respectively. Feline obesity is associated with comorbidities such as insulin resistance and hepatic lipidosis. Several risk factors are associated with obesity including middle age, neuter status, decreased activity, and diet. Obesity management is multifaceted and includes client education, diet modification, and consistent monitoring. Successful obesity management may be dependent on owner perception of their cat's quality of life during a prescribed weight loss plan. Poor quality of life perception may result in failure to complete the weight loss process. Food toys may be used to enhance environmental enrichment, allow cats to express their natural predatory behavior and overall improve owner-perceived quality of life. Therefore, we set out to investigate the role of food toys in owner-perceived quality of life of obese cats during a prescribed weight loss plan.
Fifty-five cats with a BCS > 7 were enrolled in a double-blinded weight loss study and randomized into one of two groups: food toy (n=26) or food bowl (n=29). Each cat was provided a prescribed weight loss diet and instructions. Body weight and body condition score were evaluated monthly. Additionally, owners completed a monthly questionnaire to assess their cat's quality of life.
Of the 44 cats in the final analysis, 66% (n=29) successfully completed the study and lost > 2 BCS points and/or achieved an ideal BCS of 5/9. Low-calorie vegetables were offered to the majority of cats (n= 32) due to owner reports of disruptive food seeking behavior. Of the cats offered vegetables, 87.5% (n=28) cats required a commercial palatant to consume the vegetables. All enrolled cats had a higher (p<0.0000) owner-perceive quality of life at the final visit/recheck/end of study (median QOL=110.0), as compared to the initial weight loss appointment (median QOL=126.0). The increase in quality of life was primarily driven by improvement in moving from one place to another, grooming and scratching, engaging in social activities, and playing and hunting. There was no effect (p=0.27) of food toy on owner-perceived quality of life.
Prescribed weight loss improves owner-perceived quality of life of obese cats. A single food toy (ball-style) was included in this study and did not appear to influence owner-perceived QOL. However, the role of food toys needs further investigation as there are several food toy styles that have not yet been investigated during a prescribed weight loss plan. We suspect that most/all of the 32 cats fed vegetables would have withdrawn from the study. Therefore, including vegetables in the prescribed weight loss plan appears to improve success of weight loss in obese cats.Master of Science

Full textAbstract:
The desire to achieve higher heat transfer augmentation for turbine blades is fueled by the increased power output and efficiency that is achievable with high turbine inlet temperatures. The use of internal cooling channels fitted with pin fin arrays serves as one method of accomplishing this goal. Consequently, the addition of pin fin arrays comes at the expense of increased pressure drop. Therefore the pin fin geometry must be judiciously chosen to achieve the required heat transfer rate while minimizing the associated pressure drop.
This project culminates in the measurement of both pin fin force and array pressure drop as they related to changes in the array geometry. Specifically, the effects of Reynolds number, spanwise pin spacing, streamwise pin spacing, pin aspect ratio, and flow incidence angle. Direct two-component force measurement is achieved with a cantilever beam force sensor that uses highly sensitive piezoresistive strain gauges, relating the strain at the base of the beam to the applied force. With proper characterization, forces as small as one-tenth the weight of a paper clip are successfully measured. Additionally, array pressure drop measurements are achieved using static pressure taps.
Experiments were conducted over a range of Reynolds numbers between 7,500 and 35,000. Changes in the spanwise pin spacing were shown to substantially alter the pin fin drag and array pressure drop, while changes in the streamwise pin spacing were less influential. The experimental results also showed a dramatic reduction in the pin fin drag and array pressure drop for an inline flow incidence angle. Finally, changes in the pin aspect ratio were shown to have little effect on the array pressure drop.

Full textAbstract:
Farmers are limited in the amount of specialty crops they can plant, harvest and market without adequate cooling to preserve commodities before sale. A cooler available at a farm would allow the farmer to harvest his produce earlier and take it to market at a later time. Cooling available on the farm will help a farmer to harvest commodities during peak harvest times and store it for future sale at multiple farmers markets or over a period of a week or more at a farm market. A cooler will give a farmer more logistical options. An indirect-direct evaporative pad cooling can provide cooling with high humidity which is sufficient to prolong shelf life. A cool room with window air conditioning (AC) was modified by adding indirect-direct evaporative cooling. The cool room was used for comparative study of produce shelf life under AC (with CoolBot), indirect-direct evaporative cooling (EC), residential AC (RES), and farm building (FB) storage. Results showed that FB had a lower shelf life because of non-conditioned space. RES was a table in an office building with a temperature of about 22°C. For produce with medium temperature requirements such as tomato, cucumber, and green pepper the shelf life was prolonged more in the cooler room. Strawberry and blueberry had a much longer shelf life in a cooler. The shelf life of the blueberry stored at Cooler AC was longer about two and a half fold longer than Cooler EC and RES, and five and half fold longer than FB. The shelf life of the strawberry in Cooler AC was longer one-fold than Cooler EC, two and a half fold longer than RES, and five-fold longer than FB. The shelf life of green pepper stored in Cooler AC was longer fivefold than Cooler EC and nine and a half fold longer than RES and FB. The shelf life of cucumber stored at Cooler AC was longer two fold than Cooler EC and 3.3-fold longer than RES and four fold longer than FB. The shelf life of tomato stored at Cooler AC was longer 1.25-fold than Cooler EC, 1.75 fold longer than RES and two and a half fold longer than FB. Generally stored fruits and vegetables in Cooler AC was maintained quality with minimal weight loss that allows a farmer to store their produce while maintaining shelf life. Cooler EC can be used to store produce for a shorter time with higher weight loss. Finally, FB had a shorter shelf life due to the non-conditioned space.

Full textAbstract:
This dissertation uses quantitative data on city cinematography and the morphological study of filming locations to identify how differences in ways of seeing cities, as shaped by cinematographic choices, are anchored both in differences in what is physically present as well as in differences in frameworks and expectations about what might be interesting or important to see.
Four films are evaluated that are set in Los Angeles and New York, two cities recognized as paradigms in American urbanism: The Naked City (1948), The Long Goodbye (1970), Goodfellas (1990), and Pulp Fiction (1994). In general, the New York movies suggest the embeddedness of the individual in the city and its social life in ways tied closely to urban form, with the visual presentation of the street acting as an index to the position of the individual within the narrative. Los Angeles, by contrast, presents the city as a series of enclaves linked by infrastructure. The street as a sociologically relevant entity hardly exists, with the exception of a handful of chase scenes, as though only crisis can catalyze direct encounters with the streets of Los Angeles.
Within individual movies, the depiction of city form reveals directorial idioms in the presentation of the narrative. The Naked City exploits corner shots to impart greater visual interest to the presentation of activity in the streets. The Long Goodbye shows the degradation of the distinction between public and private space as concurrent with a city form and culture that resists decoding. Goodfellas develops a grammar of views on the street that corresponds to the relationships of individual characters to overlapping social groups over time. Pulp Fiction mainly presents city locations as decontextualized to focus on dialogue and relationships, to sculpt urban form to meet the exigencies of the narrative, and to all the more powerfully introduce surprise.
In the concluding chapter, the qualities of the city as presented in Goodfellas and Pulp Fiction and both of the cities are diagrammed and discussed relative to architectural precedents and ideas that might inform architectural design.

Full textAbstract:
E-cadherin (Cdh1), is a major component of epithelial adherens junctions, binds the Wnt pathway effector β-catenin and is lost at the invasive edge of colon cancers. Crypt stem cells give rise to 4 cell lineages that, with the exception of Paneth cells, travel along the crypt-villus axis over 3 days and are shed by anoikis. Gain of function of the Wnt pathway by a mutation in Adenomatous Polyposis Coli (Apc) disrupts enterocyte turnover to result in adenoma formation. Homozygote null Cdh1 is embryonic lethal, and heterozygote Cdh1 can promote Apc1638N induced adenoma formation, but we lack models that assess additional functions of Cdh1 in the adenoma to carcinoma transition. The aim of this thesis was to evaluate the effect of Cdh1 loss of function in the murine intestine, including in the setting of Wnt pathway activation. To do this, germline and intestinal specific conditional Cdh1 loss of function models were generated. Conditional homozygous deletion of Cdh1 resulted in embryonic lethality using Villin-Cre. In adults, homozygous Cdh1 loss using the tamoxifen inducible Villin-CreERT2 led to intestinal inflammation, bacteraemia and disrupted crypt-villus architecture. Combined conditional homozygous deletion of Cdh1 and Apc resulted in Wnt pathway upregulation assessed by β-catenin immunolabelling. Strain dependent effects of Cdh1 heterozygosity were apparent on the Apc heterozygote background: ApcMin/+ Cdh1+/- (C57BL/6J) had no effect on survival or adenoma phenotype compared to littermate ApcMin/+; Cdh1+/fl increased adenoma burden in Apc+/fl Vil-Cre animals (B6D2/C57BL/6J). Low frequency recombination of Apcfl/fl using Lgr5-EGFP-IRES-CreERT2 bypasses the loss of heterozygosity event relied on in heterozygous Apc tumour models achieving a large adenoma burden within 4 weeks. Cdh1 loss did not alter survival or adenoma phenotype in this model, including the development of large caecal tumours. Immunolabelling of tumours from Apcfl/fl Cdh1fl/fl animals showed persistent E-cadherin protein expression, suggesting incomplete recombination or that double homozygote enterocytes failed to survive. In vitro adenoma culture was used to test whether E-cadherin loss was incompatible with enterocyte survival in the setting of Wnt activation. Apcfl/fl Cdh1+/+ and Apcfl/fl Cdh1fl/fl adenoma were cultured in matrigel and treated with an adenovirus expressing Cre recombinase under a CMV promoter (Ad-Cre). Ad-Cre had no effect on Apcfl/fl Cdh1+/+ adenoma growth. Ad-Cre treated Apcfl/fl Cdh1fl/fl adenoma organoids showed cells where E‑cadherin loss resulted in Wnt pathway upregulation as assessed by nuclear β-catenin and Axin2 expression, and epithelial mesenchymal transition shown by upregulation of fibronectin, twist and vimentin. This work supports a role for E-cadherin in modulation of the Wnt pathway. Further investigation is required to define the cell adhesion versus Wnt regulatory functions of E-cadherin.

Full textAbstract:
Losing a spouse is as devastating an experience anyone will ever deal with in his or her life. Research, however, shows that men have a harder and longer time coping with the loss of a spouse than women. When the widower’s profession is farming, there are no resources to specifically help that individual with their loss. The purpose of this research was to gain insight into the lives of widowed farmers with particular focus on transitions in their farming operation and their family life. Through their stories, we learn what is happening before the loss of the female spouse on the farm, during the bereavement period, and how the farmer handles the situation after the bereavement period has ended. Findings indicate that the Cooperative Extension Service can play a major role in supporting our widowed farmers as they seek a new normal for their farm operation and family life. Also, farming widowers have more stress following the loss of a spouse due to the added aspect of managing the farm and the home simultaneously after the passing of their spouse. Recommendations include further expanding spousal bereavement materials to include a section for males and in particular farming widowers.

Full textAbstract:
Approximately 15% of Swedish people experience tinnitus, but only 2.4% experience severe problems. Treatment modalities for tinnitus vary, but the most common treatment is counseling. The majority of patients with tinnitus report some degree of hearing loss, and hearing aids have been used for many years in patients who suffer from both tinnitus and hearing impairment. The aim of the present thesis was to investigate disease management, determine quality of life and identify treatment strategies for patients with tinnitus and sensorineural hearing loss. The first two studies described here are retrospective, descriptive studies of patients who sought care for tinnitus and hearing loss at two Ear-Nose-Throat (ENT) clinics in Östergötland County, Sweden, during the years 2004 - 2007. Study I showed that 70% of the cohort had tinnitus; however, many did not initially receive a diagnosis of tinnitus. Information about vertigo, heredity for hearing loss and tinnitus, diabetes history, cardiovascular disease history and other factors related to health was often missing from the patients’ medical records. The results could show that the overall scores using the Tinnitus Handicap Inventory (THI) were higher in female patients than in male patients. Although it is likely that hearing aids would be beneficial for the majority of these patients, 314 (44%) of the 714 total patients had hearing aids. Furthermore, the outcomes from study II demonstrated that a majority of the patients (61%) who were dissatisfied with the care they had obtained had no hearing aids. This finding may indicate that the fitting of hearing aids is an important treatment for patients with both tinnitus and hearing loss. Studies III and IV were prospective studies. Data collection was based on patients who sought care for tinnitus and/or hearing loss at the ENT clinic in Linköping during 2012-2013. In study III, 92 patients were divided into two groups: one group contained individuals with both tinnitus and hearing loss, and the other group contained patients with only hearing loss. The patients were assessed using the Reading Span test, the Hearing in Noise Test (HINT) and three questionnaires (the THI, the Hearing Handicap Inventory for Elderly and the Pittsburg Sleep Quality Index) at baseline and follow-up. The results from the age-matched subgroups (n=30+30) generated from the full clinical groups (46+46) showed significantly improved Reading Span test performance and sleep quality in patients with both tinnitus and hearing loss. Similar results were observed in our full clinical population (n=46+46). However, the interpretation of this finding is difficult due to age differences between the groups. In conclusion, hearing aid fitting had a significantly positive impact on working memory capacity and sleep quality in patients with both tinnitus and hearing loss compared with patients with only hearing loss. In study IV, a brief Motivational Interviewing (MI) guide was integrated into the hearing rehabilitation process for 23 patients with both tinnitus and hearing loss, and they were compared against a control group (n=23) of patients with both tinnitus and hearing loss who underwent traditional hearing rehabilitation. The results showed that the patients who received the brief MI guide required fewer visits to complete their hearing rehabilitation compared with the patients in the control group. In addition, there was a significant difference in THI scores between the groups, which indicated that the intervention reduced tinnitus annoyance more in the MI group. Furthermore, both groups showed higher scores at follow-up compared with baseline on the International Outcome Inventory for Hearing Aids (IOI-HA) scale, which indicated that both approaches showed a positive effect on hearing aid satisfaction. Study V was a retrospective, descriptive study that focused on a part of a Stepped Care model and included patients who participated in half-day tinnitus information meetings from 2004 to 2011 in the audiology clinic at Linköping University Hospital. A total of 426 tinnitus patients with complete questionnaires (the THI and the Hospital Anxiety and Depression Scale, HADS) were included in the study. The results showed significant decreases in scores on the THI and the anxiety module of the HADS before and after the information session. However, there were no statistically significant changes in the depression module of the HADS. In conclusion, this thesis underscores the importance of hearing impairment, cognitive variables and motivational procedures in the management of tinnitus. Multidisciplinary group information needs to be further validated.

El objetivo de este estudio realizado es para que el público tenga más en cuenta lo que un movimiento urbano o una cultura urbana puede llegar a crecer y evolucionar con el paso de tiempo. El freestyle es un movimiento que empezó por los ochenta en Brooklyn, Estados Unidos, desde ese entonces ha sido catalogado por varios calificativos negativos por el mismo hecho que iniciado en la calle, por ejemplo, la violencia, la delincuencia, etc. Con el paso del tiempo, el freestyle ha evolucionado de manera increíble. antes del 2010, solo había un evento por año, hoy en día hay más de dos eventos por mes. Esto se ha debido por varios factores, tanto como los mismos freestylers, la comunidad de freestyle, el live streaming, etc. Por ello, la pregunta de investigación es: ¿Cómo el live stream ha beneficiado el crecimiento de The Urban Roosters en los últimos 3 años? En este contexto, la investigación ha ayudado explorar esos beneficios que se ha ido otorgando con el pasar de los años y los motivos también. La pregunta de investigación se responde a través de los estudios que se ha realizado en transcurso de todo este periodo. se ha indagado por fuentes confiables que han aportado con datos importantes, de esa manera se pueda entender todo el tema a más profundidad. Si bien es cierto, ha habido varios factores importantes para el tema, se han tomado en cuento los que han sido más relevantes e importantes en transcurso de los años.The main reason of this investigation is to make the public more aware of what an urban movement or urban culture can grow and evolve over the pass of time. Freestyle is a movement that began in the eighties in Brooklyn, United States, since then it has been classified by several negative labels for the same fact that it started on the street, for example, violence, crime, etc. Over time, freestyle has grown and evolved in an incredible way. Before 2010, there was only one event per year, nowadays there are more than two events per month. This has been due to several factors, as well as the freestylers themselves, the freestyle community, live streaming, etc. So, the research question is: How has live streaming benefited The Urban Roosters' growth in the past 3 years? In this context, the research that I´ve been looking for has helped explore those benefits that have been granted over the years and the reasons as well. The research question is answered through the studies that have been carried out throughout this period. It has been investigated by reliable sources that have provided important data, so that the whole topic can be understood in more depth. Although it is true, there have been several important factors for the subject, those that have been most relevant and important over the years have been taken into account.

Full textAbstract:
The prediction of fatigue life and evaluation of onset and growth of matrix cracks and delamination for general composite laminates are studied analytically using theories of damage tolerance, residual modulus degradation and residual strength degradation. Damage onset including matrix cracks and edge delamination are predicted by using a total strain energy release rate criterion which accounts for interactive effects of matrix cracks and delamination. The analytical models for modulus degradation, matrix crack density and delamination size growth as function of fatigue stress and fatigue cycles are proposed. The proposed approach provides four choices for predicting tension-tension fatigue life and for assessing fail-safety for structures made of composite laminates. The direct relation of physical damage to fatigue life and analytical equations for calculating residual elastic moduli E$ rm{ sb1, E sb2, v sb{12}}$ and G$ sb{12}$ in terms of fatigue load and fatigue cycles are proposed. The proposed approach enables prediction of fatigue behaviour of general laminates using experimental data of a basic lay-up such as unidirectional laminate. The finite element technique was utilized to model the fatigue failure process of notched laminates. A simple example of a laminate with a central hole under tension-tension fatigue loading was performed.

Full textAbstract:
Background: Little is known about the psychological effects on life after weight loss surgery. Results from the systematic review above showed some persisting disordered psychosocial quality of life and wellbeing in longer term follow up periods in participants after the procedure when compared to control groups. This highlighted potential need for psychological intervention post-surgery and further research to provide more data on long term psychosocial impact of weight loss surgery. Even clearer was the lack of patient perspective on their experience and needs after having the surgery. Generating qualitative post-surgery data is vital as it gives health professionals detailed information on whether patients feel psychological care is needed after surgical obesity treatment and, if so, specifically what kind of care. Therefore the study aims were; 1) to explore patients’ experiences of life after weight loss surgery, discussing perceived benefits and limitations of the procedure, and realisation of patients’ expectations AND 2) triangulate patients’ experiences with the views of health professionals involved in surgery and ongoing care to examine concordance between the cohorts. Methods: Ten individuals who had had weight loss surgery between 2 to 6 years ago and eight health professionals were recruited within an NHS bariatric surgery service through purposeful sampling and individually interviewed by the researcher. The semi-structured interviews were transcribed and analysed using thematic analysis. Findings: Patients reported drastic weight loss and improvements in a range of co-morbidities in the first year that coincided with better psychological and social function. However long term experiential narratives revealed a need for psychological aftercare to support patients through physical and psychological changes. Specifically, issues of excess skin, acceptance of non-obese self and perceived prejudice following drastic weight loss were highlighted. Discussion: Overall it would seem that weight loss surgery is a great catalyst for weight loss in those suffering from severe obesity. However, this tool needs to go hand in hand with psychological support post-surgery to aid long term optimal results. In relation to health psychology, suggestions for theoretical application and health interventions to facilitate patients through postoperative adjustments after surgery are outlined as well as recommendations for better service provision.

Full textAbstract:
There is a taboo surrounding death in our North American culture. We're not sure how to talk about it, or how to connect through it. The HBO series Six Feet Under breaks this taboo with its honest, humorous and moving look at death and dying. There are important lessons to be drawn from this series. Teachers could revolutionize their classrooms as this show has revolutionized television: by dealing with issues that most tend to avoid. Parker Palmer and Mary Rose O'Reilley's views on education provide a foundation for this thesis. First, teachers need to recognize the fragility of their students as well as their own. Second, they need to appreciate that loss comes in many forms, and that mourning is often necessary. Third, teaching needs to create a space for both students and teachers to express themselves. Fourth, this space also needs to exist in order for both teachers and students to truly listen to one another. Fifth, teachers need to change their own perception of death and dying if they expect students to do the same. Last, teachers need to promote the idea of connection with the world outside the classroom. This thesis's intention is to bring awareness and acceptance around death and dying to individuals, particularly teachers, by exploring Six Feet Under through the characters' journeys, and extracting its many valuable lessons.

Full textAbstract:
La alteración de la capacidad reproductiva es un problema frecuente en nuestra sociedad, su prevalencia se sitúa en torno al 15%. Los estudios epidemiológicos realizados en Europa demuestran que las parejas que buscan una gestación lo consiguen entre un 80-85% en el primer año. Por lo tanto hay millones de personas en todo el mundo que están luchando contra los problemas reproductivos. Estos trastornos de la capacidad reproductiva se deben a múltiples factores, ocupando un lugar preeminente la edad de la mujer, no siendo ello una patología “per se” sino, una consecuencia de la evolución psicológica y social de la mujer en los últimos años. De esta forma, se observa como las alteraciones de la capacidad reproductiva, que a menudo tratamos de definir como una disfunción fisiológica más, es un hecho biológico con importantes componentes psicológicos y sociales.
El aumento de las alteraciones de la fertilidad unido a los espectaculares avances que ha experimentado la Medicina Reproductiva en la última década se ha traducido en un importante incremento del número de usuarios. Son muchas las parejas y mujeres solas que hoy en día en nuestro país se benefician de los tratamientos de fertilidad. Sin embargo, el componente emocional del problema y del proceso ha recibido mucha menos atención. Este hecho es debido en parte, a que los profesionales implicados poseen formación biomédica y basan su atención en modelos asistenciales con una visión molecular de la patología dentro de un marco conceptual sobre salud y enfermedad de mentalidad anatomoclínica, etipatogénica y fisiopatológica, que gira en torno a la eficacia y seguridad del proceso. Esta búsqueda de máximo rendimiento terapéutico ha llevado en muchas ocasiones a minimizar el impacto emocional que sufren los pacientes en estos procesos.
Este sufrimiento emocional ha sido ampliamente estudiado por profesionales de la salud mental, surgiendo la idea de crisis vital que conlleva; vulnerabilidad, depresión, ansiedad y baja autoestima.
Es, en este contexto emocional, donde los pacientes deben tomar unas decisiones que no solo van a tener repercusiones a corto plazo, sino que van a condicionar el resto de sus vidas. Dos de los factores que contribuyen de forma importante a la toma inadecuada de decisiones son: la falta de información completa sobre las consecuencias de las mismas y, la percepción de insatisfacción con el tratamiento principalmente, en la fase de estimulación ovárica (EO) con la subsecuente ansiedad generada ante la posibilidad de tener que repetir el ciclo. Estos dos factores pueden llevar a buscar el embarazo a cualquier precio.
En esta tesis se ha pretendido estudiar el impacto psicosocial para los progenitores, de las decisiones tomadas bajo un paradigma resultadista. Concretamente de los nacimientos múltiples como resultado de la aceptación de la transferencia embrionaria de dos o más embriones y por tanto el embarazo múltiple con el fin de aumentar las tasa de implantación. Una vez evidenciados estos riesgos, se desarrolló un instrumento orientado a conocer el grado de satisfacción de las pacientes en la fase de EO, con el objetivo de poder intervenir en las variables clínicas para minimizar su impacto.
La tesis doctoral que a continuación presentamos está formada por cuatro estudios que pertenecen a una misma línea de investigación. El objetivo general y común a todos ellos se focaliza en analizar las repercusiones psicosociales de pacientes que tienen más de un hijo por parto como consecuencia de un tratamiento de Fecundación In Vitro (FIV).
De los cuatro estudios que componen este trabajo doctoral, dos de ellos han sido publicados en Fertility and Sterilty. Esta es la revista oficial de la American Society for Reproductive Medicine (ASRM), con un factor de impacto de 4,175.
Otro de ellos ha sido publicado en el Journal of Psychosomatic obstetrics & Gynecology con un factor de impacto de 1,590.
También se ha publicado en la Revista Iberoamericana de Fertilidad de amplia difusión en el ámbito de la medicina reproductiva en España con un factor de impacto de 0,10.
A continuación se presentan los objetivos específicos de los estudios realizados y el método y procedimiento empleados en cada uno de ellos. Finalmente, se exponen y discuten los resultados obtenidos, haciendo referencia a los artículos originales incluidos en la tesis, y se proponen futuras líneas de investigación.Alteration of reproductive capacity is a common problem in our society; its prevalence is around 15%. Epidemiological studies in Europe show that couples seeking pregnancy achieve it between 80-85% in the first year. Therefore, there are millions of people around the world who are struggling with reproductive problems. These reproductive problems are due to multiple factors, occupying a prominent place the woman's age, it is not a pathology "per is" fate, but a consequence of the psychological and social evolution of women in recent years. In this way, seen as alterations of reproductive capacity, which we define as a physiological dysfunction most often, it is a biological fact with important psychological and social components. The increase in fertility disorders, joined with the spectacular advances that the reproductive medicine has experienced in the last decade, has resulted in a significant increase in the number of users. There are many couples and single women in our country today who benefit from fertility treatments. However, the emotional component of the problem and the process has received much less attention. This fact is due in part, to the professionals involved having biomedical training and based their attention on health care models with molecular insight into the pathology within a conceptual framework on health and disease of mentality clinicopathological, etipatogenica and pathophysiological, which revolves around the efficacy and safety of the process. This quest for maximum therapeutic performance has led in many occasions to minimize the emotional impact suffered by patients in these processes. This emotional distress has been widely studied by the mental health professionals, emerging the idea of vital crisis involving; vulnerability, depression, anxiety and low self-esteem. It is in this emotional context, where patients must make some decisions which will not only have an impact in the short term, but will condition the rest of their lives. Two of the factors that contribute significantly to the inadequate decision-making process are: lack of detailed information and the perception of dissatisfaction with the treatment mainly at the stage of ovarian stimulation (OS) with subsequent anxiety generated at the prospect of having to repeat the cycle. These two factors can lead to aiming to get pregnancy at any price. In this thesis, we have tried to study the psychosocial impact for parents, on decisions made under an overall paradigm. Specifically of multiple births as a result of accepting the embryo transfer of two or more embryos and therefore resulting in multiple pregnancy in order to increase the number of implementation. Once these risks were found, an oriented instrument was developed to know the degree of satisfaction of the patients in the OS phase, in order to be able to intervene in the clinical variables to minimize its impact. The doctoral thesis we are presenting below consists of four studies which belong to the same line of research. The general objective of them all was to and focus on analyzing the psychosocial impacts for patients having more than one child birth as a result of the In Vitro fertilization (IVF) treatment. Two of the four studies that make up this doctoral work, have been published in Fertility and Sterilty. This is the official magazine of the American Society for Reproductive Medicine (ASRM), with an impact factor of 4,175. One of them has been published in the Journal of Psychosomatic obstetrics, with an impact factor of 1,590. The fourth article has been published in the Revista Iberoamericana de Fertilidad of wide dissemination in the field of reproductive medicine in Spain with an impact factor of 0.10. Below are the specific objectives of studies and the method and procedure used in each of them. Finally, exposed and discussed the results, referring to the original articles included in the thesis, and proposed future lines of research.

Full textAbstract:
Mass transit in the form of light rail is, in many ways, a new and revolutionary idea for the Greater Los Angeles Area. Although mass light rail transit did exist in Los Angeles in the form of the Pacific Electric Railways red car system, an extensive network of metro rail lines has never existed in Los Angeles County since Pacific Electric was dismantled and shut down in 1950. Because of this, the popular mode of transport in LA County has traditionally been cars, and public transport has consisted mostly of bus routes. This has all changed in the last few decades. Since the 1980s, LA County has conducted several studies and, as a result of those studies, has proposed to build an extensive network of light rail lines to connect the county. In more recent years, many of these project plans have been approved, and the MTA has overseen the construction and functioning of new railway lines that are connecting far-flung regions of LA County with Union Station in downtown LA. Currently, the MTA operates 5 light rail lines within LA county-the Blue Line, the Red Line, the Purple Line, the Green Line and the Gold Line-that extend north, south and east of downtown LA. Each of these lines has been functional for a varying amount of time, but current weekday ridership on this system of lines has crossed the 280,000 mark as off September 2009.

Full textAbstract:
Background:
The loss of photosynthesis has occurred often in eukaryotic evolution, even more than its acquisition, which occurred at least nine times independently and which generated the evolution of the supergroups Archaeplastida, Rhizaria, Chromalveolata and Excavata. This secondary loss of autotrophic capability is essential to explain the evolution of eukaryotes and the high diversity of protists, which has been severely underestimated until recently. However, the ecological and evolutionary scenarios behind this evolutionary ‘‘step back’’ are still largely unknown.
Methodology/Principal Findings:
Using a dynamic model of heterotrophic and mixotrophic flagellates and two types of prey, large bacteria and ultramicrobacteria, we examine the influence of DOC concentration, mixotroph’s photosynthetic growth rate, and external limitations of photosynthesis on the coexistence of both types of flagellates.
Our key premises are: large bacteria grow faster than small ones at high DOC concentrations, and vice versa; and heterotrophic flagellates are more efficient than the mixotrophs grazing small bacteria (both empirically supported). We show that differential efficiency in bacteria grazing, which strongly depends on cell size, is a key factor to explain the loss of photosynthesis in mixotrophs (which combine photosynthesis and bacterivory) leading to purely heterotrophic lineages. Further, we show in what
conditions an heterotroph mutant can coexist, or even out-compete, its mixotrophic ancestor, suggesting that bacterivory and cell size reduction may have been major triggers for the diversification of eukaryotes.
Conclusions/Significance:
Our results suggest that, provided the mixotroph’s photosynthetic advantage is not too large, the (small) heterotroph will also dominate in nutrient-poor environments and will readily invade a community of mixotrophs and bacteria, due to its higher efficiency exploiting the ultramicrobacteria. As carbon-limited conditions were presumably widespread throughout Earth history, such a scenario may explain the numerous transitions from phototrophy to mixotrophy and further to heterotrophy within virtually all major algal lineages. We challenge prevailing concepts that affiliated the evolution of phagotrophy with eutrophic or strongly light-limited environments only.

Thirty-six adult non-patients, ages 65 years and older, from the Muncie - Delaware County vicinity, were randomly selected from an available subject pool of screened volunteer respondents and randomly assigned to one of three analogue treatment conditions with two groups for each treatment condition. These three treatment conditions were the structured reminiscence life review group (SRLR), the Gestalt life review group (GLR) and a Wait List control group (WLC). Demographic, mental status, and Activities of Daily Living Scale (ADL) data were obtained from initial respondents by telephone interview and followed by written completion of the Symptom Checklist (SCL 90-R). The differential effects of treatment were measured by pre and post testing on four dependent variables: (1) depression, (2) congruence, (3) helplessness, and (4) ego integrity.Results indicated that neither of the two life review group psychotherapy treatments had any statistically significant effect upon the dependent variables. In a post hoc exploratory analysis, evidence emerged which suggested that the participants in the GLR treatment condition may have shown significant improvement on several state mental health variables. The dimensions of improvement for participants in the GLR were Interpersonal Sensitivity, Hostility, Depression, and Positive Symptom report as measured by the SCL 90-R. This contrasted with those in both the SRLR or WLC condition for whom no improvement was shown.Department of Counseling Psychology and Guidance Services

Full textAbstract:
Traumatic brain injury is a leading cause of death and disability in the United States. The injury is often composed of two processes: the primary injury, which can involve irreversible loss of tissue, and the secondary injury, which involves a cascade of reactive processes such as excitotoxicity that occur in the hours and days after the initial insult. Excitotoxic stimulation of neuronal circuits can lead to cellular dysfunction and modulation of neuronal sensitivity. One mechanism of dysfunction involves the calcium-regulated phosphatase, calcineurin. Calcineurin has been shown to be involved in the modulation of the neuronal post-synaptic structures known as dendritic spines. One means by which CaN regulates spine structure is through the dephosphorylation of the down-stream effector proteins such as, cofilin. This study tracks the changes in CaN activity levels as well as the phosphorylation state of cofilin in the cortex and hippocampus in each hemisphere of the laterally injured brain. We report that the lateral brain injury causes an increase in CaN activity in the hippocampus with a corresponding dephosphorylation of cofilin. Trauma-induced changes in CaN follow a slightly different time course in cortical tissue, as there is a biphasic modulation of cofilin that begins with an increased phosphorylation which is followed by an extended dephosphorylation. This dephosphorylation is partially prevented by a single post-injury injection of FK506, a calcineurin inhibitor. Since dephosphorylation of cofilin is a rate-limiting step in dendritic spine collapse, the results of this study demonstrate a potential cellular mechanism through which traumatic brain injury results in altered neuronal function.

Collins-Colosi, Kelly Lynn. "Young Adult Narratives of Sibling Loss and Bereavement during Adolescence." ScholarWorks, 2017. https://scholarworks.waldenu.edu/dissertations/3243.
Full textAbstract:
Up to 90% of adolescents in the U.S. experience a loss of a family member or friend. However, prior research on loss of a family member has focused predominantly on the adult experience (e.g., loss of a spouse), parental bereavement (loss of a child), or grief counseling as an intervention for dealing with loss. Little is known about the sibling loss experience, particularly from the point of view of the surviving sibling who suffered the loss when they were young. Thus, the purpose of this qualitative study was to explore the narratives of young adults who experienced the loss of a sibling during adolescence, and to understand the role of family, friends, and resources. This research utilized three theoretical models: Erik Erickson's theory of Psychosocial Development, Murray Bowen's theory of Family Systems, and Theresa Rando's 6 R's theory of loss. Eight participants (all female) between 18 and 30 years who lost a sibling between 13 and 18 years were invited through posting in 4 closed sibling loss groups on Facebook. Using Reissman's thematic analysis, data from semi-structured interviews revealed five themes: returning to school (refuge vs. struggle); being there (sources of support); emotional separation (family, friends, and the lost sibling); identification of self/moving forward (turning points following the loss); and family dynamics with departed and surviving (maintaining the lost connection). Future research should intentionally sample other demographics to broaden the understanding of sibling bereavement across age, gender, ethnicity, and religion. Positive social change implications include efforts to promote training and programs sensitive to the unique needs of bereaved young adults in secondary school and college settings.

Full textAbstract:
The concept of home is integral to much research in the field of refugee studies, which has looked at the settlement of refugees in the new home of exile, return to the lost home and, more recently, a negotiation between two or more homes through transnational practices. However, studies have rarely focused on what home actually means for those compelled to leave their homes. This thesis moves beyond a structural assessment of forced migration to look at the lived experience of Greek Cypriot and Turkish Cypriot refugees in London, in order to develop a more nuanced understanding of the meaning of home. The thesis takes as its focus four key aspects of home - the spatial, temporal, material and relational - to reveal that home for the refugee is complex, multiple and in process. What the refugee loses when they are displaced is not only the physical property of the spatial home; but also the networks and social capital of the relational home; the framed memories, repetitions of daily life and future potential of the temporal home; as well as the tastes, scents and embodied experience of the material home. It is the impossibility of all these aspects ever being reassembled, even if the physical property were to be returned, which illustrates the depth of loss that exile often represents. However, in spite of the losses they have suffered, the majority of Cypriot refugees in this study also show tremendous resilience. The findings are based on narrative interviews with Greek Cypriot and Turkish Cypriot refugees, who have lived in protracted exile in London for several decades. Contributing to a narrative turn in the field, which places the refugee at the centre rather than the margins of the research, this study recognises refugees as agents in their own lives, who are victims of circumstances rather than victims per se.

Full textAbstract:
At present, the current 4G systems provide a universal platform for broadband mobile services; however, mobile traffic is still growing at an unprecedented rate and the need for more sophisticated broadband services is pushing the limits on current standards to provide even tighter integration between wireless technologies and higher speeds. This has led to the need for a new generation of mobile communications: the so-called 5G. Although 5G systems are not expected to penetrate the market until 2020, the evolution towards 5G is widely accepted to be the logical convergence of internet services with existing mobile networking standards leading to the commonly used term “mobile internet” over heterogeneous networks, with several Gbits/s data rate and very high connectivity speeds. Therefore, to support highly increasing traffic capacity and high data rates, the next generation mobile network (5G) should extend the range of frequency spectrum for mobile communication that is yet to be identified by the ITU-R. The mm-wave spectrum is the key enabling feature of the next-generation cellular system, for which the propagation channel models need to be predicted to enhance the design guidance and the practicality of the whole design transceiver system.
The present work addresses the main concepts of the propagation channel behaviour using ray tracing software package for simulation and then results were tested and compared against practical analysis in a real-time environment. The characteristics of Indoor-Indoor (LOS and NLOS), and indoor-outdoor (NLOS) propagations channels are intensively investigated at four different frequencies; 5.8 GHz, 26GHz, 28GHz and 60GHz for vertical polarized directional, omnidirectional and isotropic antennas patterns. The computed data achieved from the 3-D Shooting and Bouncing Ray (SBR) Wireless Insite based on the effect of frequency dependent electrical properties of building materials. Ray tracing technique has been utilized to predict multipath propagation characteristics in mm-wave bands at different propagation environments. Finally, the received signal power and delay spread were computed for outdoor-outdoor complex propagation channel model at 26 GHz, 28 GHz and 60GHz frequencies and results were compared to the theoretical models.

Full textAbstract:
This study is the result of observations and questions that stem from my professional role as a senior key worker with families where a child has a life-threatening or life-shortening illness. This project explores the cultures of families where a child has been diagnosed with a potentially fatal medical condition. By examining parents' accounts, other family members' accounts and professionals' accounts of the ways treatment regimes are experienced, the study indicates typical differences in the ways life-threatening and life-shortening illnesses affect family relationships. The study also examines variations in what these illnesses 'mean' for families and the ways that treatment regimes help to shape these meanings. A combination of qualitative research methods was used via in depth, semi-structured and informal interviews with families and professionals, and included participant observation. Data was collected from five informant groups: a) mothers where a child had been diagnosed with cancer or was living with a life-shortening condition; b) families of the ill children, suffering from both cancer and from a number of severe chronic medical conditions; c) well siblings living alongside an ill sibling; d) ill children themselves; e) professionals from health and psychosocial backgrounds who worked with the families. A detailed summary of the sample may be found in Appendix 1 page 291 Although limited, the findings have helped to provide a hypothesis outlining typical differences in the ways life-threatening illnesses and lifeshortening illnesses affect family relationships. They also offer health professionals and others working with ill children insight into the crises and challenges which might typically face families during the course of their children's treatment. Medical technology is successfully prolonging the lives of children diagnosed with lifethreatening and life-shortening illnesses who would not have survived the same illness some years ago. In the light of these improvements, findings from this study indicate that when the illness is life-threatening as in childhood cancer, the treatment regimes and the sudden and frequent hospitalisation of the mother and ill child impact on the daily life of the family, changing the family dynamic and creating a sense of an emotional rollercoaster ride - with horror, hope, fear, relapse and remission all part of their journey. Conversely, findings suggest that in cases of rare, often difficult to diagnose, lifeshortening conditions, the family is drawn into a life-long up-hill struggle where the medical management of the child takes priority over, and increasingly dictates, other family members' relationships, roles and activities. Unlike the intermittent but extreme crises of life-threatening illnesses such as cancer, life-shortening conditions continue for the lifetime of the child, creating enduring long-term pressures on the family. However, in both categories of illness the families' lives are entwined with various professionals who appear largely unaware of how the medical management of these illnesses drain the practical, financial and emotional resources of the family. The findings of this research raise implications for practice and future policy. I conclude by suggesting that there is a need for an increased understanding, acknowledgement and respect from professionals that the primary carers in both categories of illness are to a greater or lesser extent, experts in their own children's illnesses. NHS Trusts, Children's Hospices and Children's Agencies produce a variety of care pathways for sick children, and although training in communication with patients is already in place, there is considerable room for improving the day-to day skills and approaches of the various professionals, particularly health professionals involved in paediatrics and their communication with the parents and the ill child. There is also a need for increased understanding by professionals of the particular daily challenges faced by families with children undergoing treatment for these conditions.
