A review of aeroplane spin literature is presented, including early spin research history and lessons learned from spinning trials. Despite many years of experience in spinning evaluation, it is difficult to predict spin characteristics and problems have been encountered and several prototype aeroplanes have been lost. No currently published method will reliably predict an aeroplane’s spin recovery characteristics. Quantitative data is required to study the spin motion of the aeroplane in adequate detail. An alternative method, Vision Based State Estimation, has been used to capture the spin motion. This alternative method has produced unique illustrations of the spinning research aeroplane and data has been obtained that could possibly be very challenging to obtain using traditional methods. To investigate the aerodynamic flow of a spinning aeroplane, flights have been flown using wool tufts on wing, aft fuselage and empennage for flow visualization. To complement the tuft observations, the differential pressure between the upper and lower horizontal tail and wing surfaces have been measured at selected points. Tufts indicate that a large-scale Upper Surface Vortex forms on the outside wing. This USV has also been visualized using a smoke source. The flow structures on top of both wings, and on top of the horizontal tail surfaces, have also been studied on another aeroplane model. The development of these rotational flow effects has been related to the spin motion. It is hypothesized that the flow structure of the turbulent boundary layer on the outside upper wing surface is due to additional accelerations induced by the rotational motion of the aeroplane. The dynamic effects have been discussed and their importance for the development of the spin considered. In addition, it is suggested that another dynamic effect might exist due to the additional acceleration of the turbulent boundary layer due to the rotational motion of the aeroplane. It is recommended that future spin recovery prediction methods account for dynamic effects, in addition to aerodynamic control effectiveness and aeroplane inertia, since the spin entry phase is important for the subsequent development of the spin. Finally, suggestions for future research are given.

Superstitions flourish in cultures around the word and in everyday life. Superstitions are so prevalent and influence personal and political decisions, therefore, we sought to develop a classroom demonstration of superstitious behavior that could be used to show quickly and effectively how powerful adventitious reinforcement could be in modifying behavior. An online game was developed and played by one hundred thirteen university students enrolled in a class on critical thinking. Participants gained points (reinforcement) arbitrarily during either 25% or 50% of each game's (A or B) 3 minute duration. Although points were non-contingent, students often engaged in superstations rules or patterns. Results of both self-reports and computer generated data showed, the games were successful in producing superstitious behavior patterns in about 50% of our participants. More students showed superstitious behavior in the 50% game than in the 25% game. We conclude that this is due to the higher reinforcement rate of in 50% game. For future studies, rearranging the stimulus array into a pattern that does not itself strongly control behavior could help refine the results.

The current investigation used qualitative methodology to examine adolescent girls’ perceptions of control over their eating, as well as triggers, and consequences of binge and related eating behaviors. Focus groups were completed with 19 adolescent girls (aged 13-17, 58% African American, 41% White) who endorsed the behaviors. Responses to focus group questions were qualitatively analyzed using a grounded theory approach and constant comparison coding. Results reflected a fundamental lack of awareness of the loss of control (LOC) eating behaviors. Yet, the data did reflect a central theme of the need to affirm independence and autonomy through eating behaviors via three distinct pathways; asserting physical, emotional, and relational control with food. Each strategy produces different positive and negative consequences regarding emotions and physical sensations. This study suggests that adolescent need for autonomy interacts with a sense of feeling out of control of one’s external environment and insufficient coping mechanisms may increase susceptibility to maladaptive eating behaviors.

Nowadays, we can meet with the connection of businesses throughout the globalized world making the consolidation of an increasingly gains importance. The thesis focuses on a group of bakeries that shares are publicly traded on the capital market in EU. That is why they have to prepare the consolidated financial statements in accordance with IFRS at the end of the reporting period. The thesis is divided into two thematic parts. The first part is focused on explaining the process of consolidation. Readers will learn the definitions, how to prepare consolidated financial statements and its purpose. The second part, which I regard as crucial, is focused on explaining the problems of loss of control. Both parts are explained in the illustrative examples for better understanding.

Iniciado em 1986, o sistema utiliza captação de mananciais hídricos subterrâneos e superficiais para produzir aproximadamente 17% do volume distribuído de água na Região Metropolitana do Recife. Devido à falta de manutenção e estrutura antiga do sistema Botafogo, há uma grande perda de volume de água, gerando problemas como falta de água para a população, perdas financeiras para a Companhia Pernambucana de Saneamento e, principalmente, impactos negativos ao meio ambiente. O presente trabalho aborda os principais impactos ambientais ocasionados por perdas de água em rede de distribuição, no período de novembro de 2014 a outubro de 2015 e propõe a aplicação de uma metodologia de estruturação de problemas, SSM (Soft Systems Methodology) para apontar possíveis ações de redução dos impactos ambientais analisados. Os dados de índices de perdas por distribuição utilizados neste trabalho foram disponibilizados pela Companhia Pernambucana de Saneamento. / The responsible system for providing treated water in the city of Olinda / PE is the Botafogo system. Started in 1986, the system uses capture of underground and surface water sources to produce approximately 17% of the distributed water volume in the Metropolitan Region of Recife. Due to lack of maintenance and former Botafogo system structure, there is a large loss of water volume, causing problems such as lack of water for the population, financial losses for the Pernambuco Sanitation Company (Compesa) and mainly negative impacts to the environment. This work addresses the main environmental impacts caused by loss of water distribution network in the period from November 2014 to October 2015 and proposes to apply a problem-structuring methodology, SSM (Soft Systems Methodology) to identify possible actions of reduction of environmental impacts analyzed. Rates of data loss by distribution used in this study were provided by the Pernambuco Sanitation Company (COMPESA).

Five fan fictions based on the TV-series Shadowhunters are used to analyze the self-harming behaviors of the character Alec Lightwood, as a response to losing, and a method of regaining, control. In addition, this paper explores self-harm in relation to upbringing and culture, self-punishment, and the mental health disorders depression and anxiety. Furthermore, it employs a disability narrative perspective and utilizes two four-stage systems proposed by disability narrative theorist David A. Karp—the illness identity career and the process of adaptations—in order to demonstrate the similarities and differences between fictional and nonfictional disability narratives. The engagement in self-harm is posited to be driven by a desire to regain control, which inadvertently ends up providing the opposite: an increased loss of control, and a hindrance for recovery.

OBJECTIVE: Research has shown a clear relationship between perfectionism and other pathology including eating disorders, typically restrictive and purging disorders such as Anorexia Nervosa and Bulimia Nervosa. However, the relationship between perfectionism and loss of control eating disorder had not been explored. Similarly, we suspect there to be a relationship between perfectionism and self-discrepancy, and that shame might be a mediating variable in the relationship between these constructs and loss of control eating. This study investigated the relationship between these three variables to better understand how shame mediates or moderates the relationship between perfectionism, self-discrepancy, and loss of control eating. METHOD: In Phase 1 College students (N = 502) completed a screening survey including Frost's Multidimensional Perfectionism Scale to assess participants' levels of perfectionism, the Integrated Self Discrepancy Index to assess their self-discrepancy scores to assess their baseline perfectionism and actual:ought self-discrepancy levels. This survey also determined whether participants met the inclusion criteria for Phase 2 (N = 15), two loss of control eating episodes per week over the past two weeks, where they received a daily survey via text for 10 days assessing their level of shame and eating behaviors the previous day. At the end of the 10 days, a multi-level regression model was conducted to determine the relationship between perfectionism, self-discrepancy (actual:ought) and loss of control eating, and the role of shame in that relationship. RESULTS AND CONCLUSION: Results found shame to be a strong moderating factor for loss of control eating behaviors, holding perfectionism, and actual:ought self-discrepancy at their mean, but not when self-discrepancy and perfectionism were both higher or lower than the mean. When the discrepancy was high and perfectionism was at its mean, and when perfectionism was low and discrepancy was at its mean, shame was a robust predictor of loss of control eating. However, when perfectionism was high and discrepancy was at its mean, shame was not found to predict loss of control eating. When perfectionism was low and discrepancy was high, shame was found to be a very strong predictor of loss of control eating. Lastly, when perfectionism was high and discrepancy was low, shame was a moderate predictor of loss of control eating. This suggests that perfectionism may be a construct that may lead to more LOCE in individuals that already experience it, but it alone is not a risk factor. It may also suggest that while general maladaptive perfectionism is not a risk factor, more specific subsets could have a stronger relationship with LOCE. The results also show that actual:ought self-discrepancy is a more significant predictor of LOCE.

Objective: Emerging prospective evidence from mixed samples, mostly covering short-term follow-up periods, suggests that childhood loss of control (LOC) eating predicts significant impairment in mental and physical health. This study sought to investigate the natural course of childhood LOC eating over the long term and in relation to binge eating disorder (BED) diagnosis, psychopathology, and body weight trajectory in the community. Method: A total of 60 children (8-13 years) with LOC eating within the past three months and 60 demographically-matched children without LOC history were assessed with the Eating Disorder Examination adapted for Children and self-report questionnaires over a 5.5 year follow-up period. Missing data were imputed. Results: Over follow-up, 38.3% of children showed persistent LOC eating, and 28.3% revealed an onset of LOC eating. Persistent LOC eating significantly predicted onset of partial-/full-syndrome BED at follow-up. Negative prognostic effects on eating disorder psychopathology, depressive symptoms, and body mass index were non-significant. Discussion: The results indicate a moderate stability of LOC eating over the long term. LOC eating, especially if stable, was suggested as a variable risk factor of clinically relevant eating disturbances. In contrast, a prognostic value for psychopathology and body mass index was not confirmed.

(1) Background: Research on parental feeding practices and non-normative eating behavior including loss of control (LOC) eating and eating disorder psychopathology indicated separate associations of these variables with child weight status, especially in early childhood. This study cross-sectionally examined interaction effects of restriction, monitoring, pressure to eat, and children’s weight status on disordered eating in children aged 8–13 years. (2) Methods: A population-based sample of N = 904 children and their mothers completed the Eating Disorder Examination Questionnaire for Children and the Child Feeding Questionnaire. Child anthropometrics were objectively measured. Hierarchical linear and logistic regression analyses were conducted for cross-sectionally predicting global eating disorder psychopathology and recurrent LOC eating by feeding practices and child weight status for younger (8–10 years) and older (11–13 years) ages. (3) Results: Restriction x Child weight status significantly predicted global eating disorder psychopathology in younger children and recurrent LOC eating in older children. Monitoring x Child weight status significantly predicted eating disorder psychopathology in older children. A higher versus lower child weight status was associated with adverse eating behaviors, particularly in children with mothers reporting high restriction and monitoring. (4) Conclusions: Detrimental associations between higher child weight status and child eating disorder symptomatology held especially true for children whose mothers strongly control child food intake.

Objective: Loss of control (LOC) eating is a salient indicator of eating disorder psychopathology in adolescents and is associated with marked distress. While research has focused on the relevance of episode size, clinical significance of LOC eating frequency has rarely been explored. Therefore, this study aimed at identifying LOC eating prevalence with respect to its recurrence and associated variables in a community-based sample. Method: Participants were 1643 adolescents, aged 12-20 years (62.4% female). Based on EDE-Q self-report, participants were categorized as those reporting recurrent (N = 156; 9.5%), non-recurrent (N = 226; 13.8%) and no LOC eating (N = 1261; 76.7%). Results: Adolescents with recurrent LOC eating reported clinically relevant and significantly greater eating disorder psychopathology, functional impairment and distress because of LOC eating, and a significantly higher body mass index (BMI, kg/m2) than adolescents with non-recurrent and those without LOC eating. Discussion: These results underline that LOC eating is a common eating behavior among adolescents in the community associated with clinical characteristics of eating disorders, and could therefore be a risk factor for developing full- or partial-syndrome eating disorders. Further research on the classification of eating disorders in adolescents with LOC eating and severity indicators is warranted.
