The Reciprocal Relationship Between Group Therapeutic Relationships and Group Member Symptom Improvement: An Archival Analysis

Rands, Aileen Marie 14 April 2022 (has links)
Researchers and clinicians have long recognized that therapeutic relationships play a fundamental role in client symptom change during treatment. At the same time, it has been proposed that improvement in client symptoms is associated with improvement in therapeutic relationships. To date, very few studies have investigated this reciprocal relationship; even fewer have examined group therapeutic relationship factors. The present study is an archival analysis on Group Questionnaire (GQ) (i.e., positive bond, positive work, and negative relationship) and Outcome Questionnaire (OQ-45) data that aims to analyze the reciprocal relationship between group therapeutic relationships and client symptom change. More specifically, this study replicates and expands upon pioneer studies in this area (i.e., Tasca & Lampard, 2012; Tasca et al., 2016b; Obeid et al., 2018). Various analyses were used to address the proposed research questions (i.e., bivariate cross-lagged panel model (CLPM), latent growth curve model with structured residuals (LGC-SR), latent change score model with change-to-change coupling (LCS-CC), and three-level multilevel models). Results indicate weak evidence of a reciprocal relationship between group therapeutic relationships and client symptom change. Further, results indicate that therapeutic relationship quality is more dominant in predicting client symptoms change compared to the reciprocal. Evidence of this was found for each subscale of the GQ as it assessed various aspects of group therapeutic relationships (i.e., positive bond, positive work, negative relationship). These results highlight the importance of group therapeutic relationships in explaining outcome.

[pt] COMEÇAR PELO FIM: PERCORRENDO A FORMAÇÃO PARA E PELO NEGATIVO NA FENOMENOLOGIA DE HEGEL / [en] TO BEGIN FROM THE END: FOLLOWING THE PROCESS OF FORMATION TO AND THROUGH THE NEGATIVE IN HEGEL S PHENOMENOLOGY

URIEL MASSALVES DE SOUZA DO NASCIMENTO 27 January 2022 (has links)
[pt] A tese busca percorrer a formação para e pelo negativo a partir da leitura do prefácio da Fenomenologia do Espírito de Hegel. A escolha por essa seção se radica em dois fundamentos específicos: primeiro, nas afirmativas hegelianas de que o fim da formação é o seu começo, agora justificado. Nesse sentido, a leitura do prefácio após o fim do livro justificaria sua existência e o faria ser um desdobramento de todo o percurso da Fenomenologia. Segundo, na própria escrita fática hegeliana que, como é sabido, escreveu o prefácio apenas ao final de todo o percurso. Isso nos indica que com a finalização do livro Hegel estava em condições de escrever um prefácio que fosse, a um só tempo, começo e fim da obra que escolheu para introduzir seus leitores ao negativo e à dialética. Para que consigamos percorrer todo o trajeto, somos levados a outras obras e, também, a outros pontos da obra. Ao fim, a capacidade de leitura do Prefácio busca se tornar, então, a explicitação da formação atingida. / [en] This thesis tries to follow closely the process of formation of the consciousness through and to the negative in Hegel s Phenomenology of Spirit. We do so by exploring Hegel s preface section to said book and we do so for the following reasons: first, Hegel himself asserts more than once that the beginning and the end are one an the same, the only difference being the fact that the end is beginning justified; secondly, Hegel himself wrote the preface (and not an epilogue, for instance) just after he finished the book, not before. Those two factors combined together seem to tell us that Hegel himself needed his own formation before he could write the section because it s rooted in the formation itself. In our theses we put forward the notion that, by the same token, if one can close read the preface, one can be said to be formed, the reading of the Preface serving as proof of the conclusion of the formative process.

"Men du är ju muslim det kan väl du svara på?" : En kvalitativ intervjustudie om unga muslimska kvinnors upplevelser av religionsundervisningens framställning av islam / "But you are a Musim, can´t you answer that?" : A qualitative interview study on young Muslim women's experiences of religious education's presentation of Islam

Taddese, Mariam January 2022 (has links)
The overall aim of this study is to study what experiences young Muslim women have of religious education in Sweden. The study examines how the respondents consider Islam and Muslim women are presented in religious education. The respondents are five young Muslim women between the ages of 19 and 25. The participants have taken part in schooling in a medium-sized town located in Sweden. The participants consider the religious teaching´s portrayal of Islam and Muslim women as provocative, negative and singled out. The respondents believe that the main reason for this is the teachers lack of knowledge about Islam. The participants have experienced elements in the teaching that have affected them negatively as they felt exposed in the classroom. Islam is often presented in relation to conflicts and violence, which the participants claim creates prejudices about the religion. Since the teachers according to the respondents possess too little knowledge about Islam, the consequences according to the participants will be a superficial education. The respondents claim that the teaching of Islam and the representation of Muslim women leads to the formation of stereotypical ideas. Based on the participant´s experiences, there are several shortcomings in the religious education. Since the Swedish school´s teaching should contribute to understanding of religion in order for the students to become respectful and understanding democratic citizens, a change is required, according to the participants.

Carbon Stability of Biochar : Methods for assessment and indication / Kolstabilitet i biokol : Metoder för värdering och indication

Söderqvist, Helena January 2019 (has links)
Biochar can reduce the amount of CO2 in the atmosphere and is acknowledged as one feasible technology for negative carbon emissions. The stability of carbon in biochar is of major importance for the carbon sequestration value. A method for confident estimation of the stability is needed to make efficient priorities for the climate. The aim of this study is to identify the best available method that can be used to indicate the stability and quantify the carbon sequestration potential of biochar. The result builds on a literature review of the current state of scientific knowledge and the proposed method is tested with data from previous studies and then applied to the case of Stockholm Exergi. Biochar has a stable carbon structure, always more recalcitrant than the biomass that it derives from. However, estimations of how stable the carbon are varying a lot in the literature. Biochar is not unambiguously defined, there is rather a range of materials with different stability and the degradationis context dependent. Further discrepancy in the estimated stability derives from different experimental design and approaches to modeling the data. There is a challenge to do a proper estimation of the actual degradation, due to the long time perspective and the complexity of observation of behavior in a naturalsystem. A functional method to indicate the stability of carbon in biochar is needed because a biochar producer cannot conduct a long term trial to prove the carbon sequestration potential. Several methods have in theory the ability to indicate stability. However, the H/Corg model with the expression BC+100 emerging to be the best suited method due to its connection to measured degradation, accessibility and acceptance. The H/Corg model could be further improved by calibration and validation by collecting existing data from previous assessments. Communication of the carbon sequestration after hundred years compared to other carbon sinks should be improved to better reflect the long term carbon sequestration value of biochar. Stockholm Exergi is planning for a biochar production of 5 000 ton/year. The H/Corg method estimate that this corresponds to 9 000 – 11 500 ton CO2 per year, stable for at least hundred years. The widerange in the result derives from the different interpretations on the H/Corg method, where the different interpretations derive from the variation that previous research result shows. This is an incentive to support further development of the method. The sequestered carbon in biochar must be protected in its application to ensure the carbon sink in a trade system. Biochar in soil, green areas and concrete face the risk of being dis/re-located. However, that is not a threat to the carbon sequestration value. Biochar and biochar in a soil product sold in bags cannot account for the biochar sequestration value detached from the product, because of the risk of incineration. The future development of biochar stability assessment should in a short term assemble the existing knowledge of conducted trials and use that with knowledge of what approaches that best corresponds to the real stability of biochar. This could decrease the observed variations in the stability assessments and be used to calibrate and validate methods that could indicate stability. In the long perspective field trials and incubation trials should be done in a standardized way to assess the degradation, designed according to best practice with long trial times and consciously extrapolated data. / Biokol kan minska halten av CO2 i atmosfären och är identifierad som en möjlig teknologi för negativa CO2 utsläpp. Biokolets stabilitet har stor betydelse för dess potential. Målet med denna studie är att identifiera den bästa tillgängliga metoden för att indikera kolets stabilitet. Resultatet bygger på en litteraturgenomgång av befintligt kunskapsläge. Den föreslagna metoden testas med biokolsdata ifrån tidigare gjorda mätningar. Kolinbindningspotentialen i Stockholm Exergi’s biokolsprojekt beräknas genom att applicera metoden på förväntad biokolsproduktion. Biokol har en stabil kolstruktur, alltid mer stabil än den biomassa den härstammar ifrån. Uppskattningar av hur stabilt biokol är varierar mycket i litteraturen. Biokol är inte entydigt definierat utan är ett spann av olika material och dessutom är stabiliteten kontext beroende. Ytterligare variationer härstammar ifrån varierande experimentdesign och olika metoder som används för extrapolation av mätdata. För att beräkna kolinbindning i biokol som produceras behövs en metod som kan visa hur stabilt kolet är.Mätmetoden är resurskrävande och därför behövs istället ett samband mellan kolets innehåll/struktur och uppvisad stabilitet som kan användas i kombination med en enklare analys av det producerade biokolet för att indikera stabilitet. I teorin finns det många metoder som kan vara funktionella men enligt denna studie är H/Corg metoden i kombination med BC+100 index mest lämpligt att använda pågrund av metodens uppvisade koppling till uppmätt stabilitet, tillgänglighet och acceptans. Stockholm Exergi planerar för en biokolsproduktion på 5000 ton/år och H/Corg metoden uppskattar att detta årligen motsvarar 9 000 – 11 500 ton CO2 stabilt i minst 100 år. Spannet som resultatet uppvisar beror av den variation av uppskattad stabilitet i litteraturen och är ett incitament för att stödja en vidareutveckling av metoden. I applikationen av biokol måste kolsänkan skyddas för att kunna ingå i ett handelssystem. För biokol till jordförbättring, grönområden i staden samt biokol i betong föreligger en möjlighet att biokolet blir omflyttat eller förloras ifrån den ursprungliga applikationen, detta medför dock inte att kolsänkan går förlorad och är därför inte ett problem för värdet av kolsänkan. Däremot bör värdet av kolsänkan av biokol som säljs i konsumentförpackningar inte frikopplas ifrån biokolsprodukten eftersom det då saknas kontroll över att kolet inte bränns. Vidare studier av stabilitet av biokol bör på kort sikt innefatta insamling av befintlig data ifrån genomförda försök. Genom kunskap om hur olika faktorer inverkar på verklig och uppskattad stabilitet kan spannet av variation bättre accepteras och minska. Vidare kan insamlad data användas för att kalibrera och validera indikationsmetoder. Kommunikationen av kolsänkan av biokol och det långsiktiga värde som skiljer biokol ifrån andra mer kortsiktiga kolsänkor bör förbättras. Långsiktiga fält och inkubationsförsök bör etableras enligt kunskap om experimentell design och hantering av data för att på ett så korrekt sätt som möjligt spegla verklig stabilitet och kolsänka.

Medias presentation of the police in Malmö. A thematic analysis of three Swedish newspapers

Erlandsson, Therez January 2017 (has links)
The media can arguably be seen to have an important part in how the public view the police. A negative presentation is seen to have several grave consequences and is argued to influence the public’s confidence in the police's legitimacy. The police in Malmö have during the last decade received much attention and media coverage because of their severe issues with criminality and violence. The aim of this thesis was partly to examine how the police in Malmö is presented in printed news and what the consequences of this might be, but also to examine if the presentation of the police changed since the reorganisation of the police force in Sweden. The method used to achieve this was a thematic analysis which was used on 193 articles from three newspapers. This included a search for themes which were later compiled into measurable figures so an examination of potential trends over the covered period, the 1st of January in 2013 to the 31st December in 2016, was possible. The results showed that 71 articles were positive, 112 articles were negative and 10 articles were neutral or ambiguous. Thus, there were 41 more negative articles than positive which shows that there is a more negative presentation of the police. When examining the trends over time it showed that a change in the presentation occurs the year that the reorganisation of the police force takes effect, however, the change differs between the newspapers.

Patientens upplevelse av undertrycksbehandling och dess påverkan på livskvalitet - en litteraturstudie

Ingrup, Lina, Lindgren, Åse January 2016 (has links)
Bakgrund: Undertrycksbehandling eller Negative Pressure Wound Therapy (NPWT) är en sårbehandling som ofta används när andra behandlingar inte lyckats med läkningen av det kroniska såret. Flera forskningsstudier stödjer metodens effektivitet gällande sårläkning och bildande av granulationsvävnad, men behandlingens påverkan på patienten och dennes upplevelse av att använda behandlingen är bristfällig.Syfte: Syftet med studien var att beskriva patientens upplevelse av att genomgå undertrycksbehandling av ett sår och om behandlingen påverkar patientens livskvalitet.Metod: Litteraturstudie baserad på kvalitativa artiklar som svarade på huvudsyftet och kvantitativa artiklar som svarade på frågeställningen.Resultat: Informanterna upplevde att NPWT-enheten var ett fokus i behandlingen. Behandlingen var smärtsam och påverkade det dagliga livet och informantens självbild. Informanterna upplevde en brist på information och stöd och en inkonsekvens i vårdpersonalens kunskap och kompetens. Ingen signifikant skillnad i livskvaliteten påvisades vid jämförelse av NPWT och standard sårbehandling.Konklusion: NPWT-behandlingen upplevdes som en krävande sårbehandling där patienten utmanades både fysiskt och psykiskt. Behandlingen innebar mycket eget ansvar, var starkt förknippad med smärta och oro och ångest överskuggade målet med behandlingen. / Background: Negative Pressure Wound Therapy (NPWT) is a wound therapy, often used, when other therapies fail to heal the chronic wound. Several research studies support the effectiveness of the method regarding wound healing and granulation tissue formation, but the effect of treatment on the patient and his experience of using the treatment is lacking. Aim: The aim of the study was to describe the patient´s experience of undergoing negative pressure wound therapy and if the treatment affects the patient´s quality of life. Method: Literature review based on qualitative articles that responded to the main objective and quantitative articles that answered the research question. Results: The informants felt that the NPWT device was a focus in the treatment. The treatment was painful and affected the daily life and the informant´s self-image. The informants experienced a lack of information and support, and an inconsistency in the nursing staffs knowledge and skills. No significant difference in the quality of life were proved by comparing NPWT and standard wound treatment.Conclusion: NPWT treatment was perceived as a demanding wound treatment where the patient was challenged both physically and mentally. Treatment entailed a lot of own responsibility, was highly associated with pain and worry and anxiety overshadowed the goal of treatment.

Daily Survey of Negative Affect and Social Interactions in Young Adults with High Levels of Social Stress

Limon, Danica L. 11 August 2022 (has links)
Background: Few studies have focused on the contextual influences that impact negative affect (NA) and risk for mood disorders in young adults. Research using ecological momentary assessment (EMA) methods has shown that neurotypical adults with elevated social anxiety may be more sensitive to their social environment. To date, little is known about how types of social interactions impact autistic adults, who may show varying levels of social anxiety and social motivation. Aim: Our goal was to examine the heterogeneity in daily social experiences for autistic and socially anxious adults. Method: Using EMA surveys, we tracked daily self-reported face-to-face interactions and examined how these interactions influenced daily affect. We likewise examined how social anxiety (using the Liebowitz Social Anxiety Scale) and autism traits (using the Autism Spectrum Quotient) influenced day-to-day social experiences while controlling for potential covariates (age and biological sex). Participants consisted of 88 young adults who participated in a mental health longitudinal study. We used a multilevel model approach (MLM) to examine predictors of NA. Results: MLM analysis showed that a model with face-to-face interactions and social anxiety predictors best explained outcomes in NA. AQ scores, age, and sex covariates did not improve model fit. Social anxiety was a significant negative predictor of NA after controlling for face-to-face interaction. Conclusion: These findings highlight that autism traits do not predict NA after controlling for social anxiety, and that social anxiety interventions may improve overall moods by addressing types of interactions.

Third Line Eribulin for Triple-negative Metastatic Breast Ductal Carcinoma Resulting in Extended Progression-free Survival of 57 Months

Manthri, Sukesh, Sharma, Purva, Mejbel, Haider A., Singal, Sakshi, Jaishankar, Devapiran 13 February 2020 (has links)
Eribulin is a non-taxane microtubule inhibitor approved for the treatment of metastatic breast carcinoma after two prior chemotherapeutic regimens. We report a patient with extended progression-free survival (PFS) of more than 57 months with metastatic breast carcinoma treated with eribulin in the third-line setting. A 48-year-old lady was diagnosed with stage IIA (pT2N0M0), high grade, triple-negative, invasive ductal carcinoma (IDC) of the left breast on core needle biopsy. She underwent neoadjuvant chemotherapy with adriamycin, and cyclophosphamide followed by a negative sentinel lymph node (SLN) biopsy. Subsequent mastectomy and axillary lymph node dissection revealed a 2.5 cm, high grade, triple-negative IDC with three additional lymph nodes negative for metastatic carcinoma, consistent with the initial diagnosis. Eight months into the surveillance program, the patient developed a 2.8 cm right lower lobe (RLL) lung mass with standard uptake value (SUV) of 27 on positron emission tomography-computed tomography (PET/CT). Core needle biopsy of the lung lesion revealed sheets of poorly differentiated carcinoma, immunophenotypically compatible with the initial diagnosis of breast pathology. She then commenced single-agent paclitaxel in the 1st line metastatic setting with a significant decrease in RLL lung mass to less than 1 cm with an SUV of 1.7 noted. The patient developed progression after seven months and started 2nd line gemcitabine noting initial improvement and subsequent stable disease for a period of 12 months. Eventual progression of RLL lung nodule measuring 2.1 cm with SUV of 10 noted. Initiated 3rd line eribulin with a notable response on imaging studies within three months and with no evidence of disease (NED) on scans over the subsequent 57 months. Eribulin related mild neuropathy superimposed on previous paclitaxel associated grade 2 neuropathy required a 20% eribulin dose reduction. The patient is currently clinically and radiographically stable with plateaued serum tumor markers. Our patient has shown excellent response and tolerance to eribulin with PFS of over 57 months (nineteen times the norm) which is rare.

The Influence Mechanism of Leader Negative Emotion Display on Employees' Daily Job Crafting

Weina, Yu, Tarnoff, Karen, Zhanhao, Wang 01 January 2021 (has links)
“Micro-innovation” has become the key to sustainable business success in the context of ‘intelligent businesses'. Different from technological innovation, micro-innovation calls for employees to make use of their rich practical experience and expertise while doing the most common tasks in work. They are encouraged to put forward effective small improvements, inventions and ideas which are conducive to further practical operation. Job crafting reflects such a process in which employees spontaneously design their work, optimize work requirements and resources, and finish tasks successfully. In the past decade, scholars of organizational behaviors have studied job crafting and agreed that job crafting of employees is so significant that it will lead to continuous improvement of products (services) and further promote “micro-innovation”. Job crafting is thought to be a dynamic and continuous work process which fluctuates every day. In order to fully understand the formation process of job crafting in the real world, research scholars recently have even called for the research on job crafting in the daily level, which was ignored by previous research. Thus, we intend to focus on employees' daily job crafting, and explore the influencing factors and mechanisms of employees' daily job crafting behaviors. In addition, leaders' emotion display is regarded as an immediate response to the interaction between leaders and employees, and has a more direct impact on the employees' daily job crafting behavior. Thus, we believe that leaders ' emotion display has a much higher information value on employees ' daily behaviors. Although it has been agreed that leaders are the source of positive and negative emotion of subordinates in the workplace, negative emotion is stronger determinant of subordinates' perceptions of leaders than positive emotion. Some clues in the current relevant research literature can confirm this point of view. For example, Dasborough and his colleagues (2016) have found that subordinates could perceive and recall more negative emotional events that have occurred in the past in work situations in greater depth and detail. In addition, Wang and his colleagues (2018) have emphasized that the influence of leaders' negative emotion on their subordinates is more helpful to fully understand the motivational effect of emotion on leadership. Therefore, this study intends to open the black box and investigate the influence of leaders' negative emotion display on employees' daily job crafting. Based on the theory of Emotion as Information, this study used job daily method to examine the influence mechanism of leaders' negative emotion display on subordinates' daily job crafting. This study is based on 1389 daily data from 105 employees in a Biological Industry Co., Ltd. which is located in the North of China. Empirical research has applied multilevel structural equation model to examine the mediation effect of state self-esteem and epidemic motivation, latent moderated structural equations to examine the moderating effect of Leader-Member Exchange, and bootstrapping method to examine the moderated mediation effect of state self-esteem and epidemic motivation. The following conclusions were found: 1) Leaders' negative emotion display negatively predicted subordinates' state self-esteem; Subordinates' state self-esteem positively predicted daily job crafting; The relationship between leaders' negative emotions display and daily job crafting was mediated by subordinates ‘ state self-esteem; 2) Leaders’ negative emotion display positively predicted subordinates' epidemic motivation; Subordinates' epidemic motivation positively predicted job crafting; The relationship between leaders' negative emotions display and daily job crafting was mediated by subordinates ‘ epidemic motivation; 3) Leader-member exchange relationship moderated the relationship between leader’ s negative emotion display and subordinates ‘ state self-esteem / subordinates’ epidemic motivation. 4)The mediation effect of subordinates' state self-esteem / subordinates ' epidemic motivation is moderated by Leader-member exchange relationship. The above results not only respond to the confusion of previous research about whether Leader's negative emotion show negative effect on subordinates, but also help to take a more comprehensive look at the effect of leaders ' negative emotion display on employees' daily job crafting. In addition, the research results expand the practical research of Emotion as Information theory, clarify the influence mechanism of leaders ‘ negative emotion display on employees’ daily job crafting including affective reaction path and cognition-driven path, extend emotion display to the field of job crafting research, and further deepen the research about job crafting

Modeling Crash Frequencies At Signalized Intersections In Central Flor

Kowdla, Smitha 01 January 2004 (has links)
A high percentage of highway crashes in the United States occur at intersections. These crashes result in property damage, lost productivity, injury, and even death. Identifying intersections associated with high crash rate is very important to minimize future crashes. The purpose of this study is to develop efficient means to evaluate intersections, which may require safety improvements. The area covered by the analysis in this thesis includes Orange and Seminole Counties and the City of Orlando. The aforementioned counties and city thus represent Central Florida. Each County/City provided data that consisted of signalized intersection drawings that were either in the form of electronic or hard copies, the county's extensive crash database and a list of intersections that underwent modifications during the study period. A total of 786 intersections were used in the analysis and the crash database was made up of 4271 crashes. From the signalized intersection drawings obtained from the county's traffic engineering department, a geometry database was created to classify all intersections by the number of through lanes, number of left turning lanes, Average Annual Daily Traffic and Posted Speed limits on the Major road of the intersection. In this research, crashes and their type, e.g., rear-end, left-turn and angle as well as total crashes were investigated. Numerous models were developed first using the Poisson regression and then using the Negative Binomial approach as the data showed overdispersion. The modeling process aimed to relate geometric and traffic factors to the frequency of crashes at intersections. Expected value analysis tables were also developed to determine if an intersection had an abnormally high number of crashes. These tables can be used in assisting Traffic Engineers in identifying serious safety problems at intersections. The general models illustrated that rear-end crashes were associated with high natural logarithm of AADT on the major road and the number of lanes (major intersections, e.g. 6x4/6x6), whereas AADT on the major road did not affect left-turn crashes. Intersections with the configuration 4x2/6x2 (2 through lanes at the minor roadway) or T intersections as another category experienced an increase in left-turn crashes. Angle crashes were most frequent at one-way intersections especially in the case of 4x4 intersections. Individual models that included interaction terms with one variable at a time concluded that AADT on the major road positively influenced rear-end crashes more compared to angle and left-turn crashes. As the speed increases on the minor road, the left turn crashes are affected more when compared to angle and rear-end crashes, therefore it can be concluded that left-turn crashes are most influenced by the speed limit on the minor road compared to angle crashes and then followed by rear-end crashes. As the total number of left turn lanes increased at the intersection, thereby increasing the size of the intersection, the number of rear-end crashes increased. An overall model that contained natural logarithm of AADT on major road, total number of left turn lanes at the intersection, number of through lanes on the minor road and configuration of the intersection, as independent variables, along with interaction terms, further concluded and supported the individual models that the number of crashes (rear-end, left-turn and angle) increased as the AADT on the major road increased and the number of crashes decreased as the total number of left turn lanes at the intersection increased. Also, crashes increased as the number of through lanes on the minor road increased. The variables' interaction effects with dummies representing rear-end and left-turn crashes in the final model showed that as the AADT on the major road increased, the number of rear-end crashes increased compared to left-turn and angle crashes and also that as the total number of left turn lanes at the intersection increased, the number of left-turn crashes decreased when compared to rear-end and angle crashes. Also the number of rear-end crashes increased at major four leg intersections e.g. 6x4, 6x6 etc. This thesis demonstrated the superiority of Negative Binomial regression in modeling the frequency of crashes at signalized intersections.
