An evaluation of a secondary intervention for students whose problem behaviors are escape maintained

Boyd, Roy Justin, 1982- 06 1900 (has links)
xiii, 99 p. : ill. (some col.) / Check-in-check-out (CICO) has been demonstrated to produce decreases in problematic behaviors and increases in academic engagement when used as a secondary intervention within a school-wide positive behavior support (SWPBS) framework. In general, research has suggested that CICO is most effective for children whose problem behaviors are sensitive to adult attention without modifications. However, research is lacking on secondary interventions intended for students whose problem behaviors are hypothesized to be maintained by escape or avoidance of academic tasks. Drawing from research on the utility of function-based interventions and the teaching of functional replacement behaviors to decrease problem behaviors and increase appropriate skills, a secondary intervention, Breaks are Better (BrB), was designed that builds off core features of CICO but also includes function-based components for addressing problem behavior maintained by task avoidance. Modifications included 1) defining specific expectations that were incompatible with problematic behavior during academic routines and 2) providing students with functional replacement behaviors that allowed them to recruit both brief breaks and help. Effectiveness of BrB was examined using an ABAB design across three participants whose off-task behaviors were hypothesized to be maintained, in part, by task avoidance or escape. The current study examined the following primary research questions: 1) is there a functional relation between the implementation of BrB and reduced rates of off-task behavior, and 2) is there a functional relation between the implementation of BrB and increases in the use of alternative replacement behaviors (help and break)? A functional relation was documented between the implementation of the BrB intervention and reductions in off-task behavior for two out of three participants (Gregg and Alex). However, for Diego, off-task behavior was somewhat variable during the final intervention phase. Results from the collection of contextual fit and social validity data indicated that students, teachers, and parents viewed BrB as effective, worth the required effort, and contextually appropriate for use in this school. / Committee in charge: Cynthia M.

Postoj sester a porodních asistentek k preventivním prohlídkám / Attitude to Prophylactic Check-ups among Nurses and Midwives

LENKEROVÁ, Petra January 2013 (has links)
Abstract The thesis focuses on an insight into the attitude to prophylactic check-ups among nurses and midwives. The theoretical part deals with health, prevention, prophylactic check-ups, characteristics of attitudes and education. The role of nurses and midwives in prevention, definition of competences and lifestyle problems in relation to healthcare job performance is not omitted. The aim of the thesis was to find out whether nurses and midwives themselves regularly have prophylactic check-ups and how they approach the information on necessity of prophylactic check-ups in the public. Quantitative method was applied to the research. An anonymous questionnaire research among nurses and midwives working in primary care and in hospitals was used as the data collection technique. The total number of questionnaires returned from the respondents was 270, 91 were returned from primary care and 179 from hospitals. None of the questionnaires had to be rejected for incompleteness. A pilot study was performed within the research, where 10 questionnaires were handed out evenly to the primary care sector and to the hospital sector to verify whether no serious problems with their completion occured. Thanks to their correct completion they were included into the main research. The monitored hypotheses were statistically evaluated by means of the Pearson's Chi-Square Test and Fisher?s Test with low values in contingency tables. The fact whether participation of nurses and midwives in prophylactic check-ups differs with age was evaluated. The frequency of regular prophylactic check-ups was 62 per cent at the age below 40 and 98 per cent at the age over 40. Age has significant influence on medical prophylactic check-up attendance. Education level does not have statistically significant influence on prophylactic check-up attendance. The research has not completely refuted difference in prophylactic check-up attendance according to workplace type. Nurses and midwives working in hospitals have prophylactic check-ups less regularly than those working in primary care. Nurses and midwives in primary care are demonstrably older and they go to prophylactic check-ups more regularly. The difference in approach to prophylactic check-ups among nurses and midwives according to workplace type was monitored. Nurses and midwives have positive attitude to prophylactic check-ups regardless of the type of their workplace. They belong to the most frequent activities they apply to maintenance and improvement of their health condition. Nurses and midwives are first of all motivated to regular visits of prophylactic check-ups by the care of their own health. Statistical level was achieved in the tests for the total number of nurses and midwives regularly attending prophylactic check-ups and educating patients. The research has confirmed that nurses and midwives that regularly visit prophylactic check-ups have more positive approach to providing information to clients-patients than those that do not undergo the prophylactic check-ups. Nurses and midwives in hospitals pay more attention to the disease itself and to prevention of possible complications in patients than to general prevention and prophylactic check-ups in their educational activities. With regard to the set goals the final evaluation of the research has confirmed that nurses and midwives have positive approach to prophylactic check-ups and try to visit them regularly. Respondents from the primary care are older and visit the prophylactic check-ups more regularly. Prophylactic check-ups have priority in health condition support and maintenance for the respondents. The research has shown that the respondents working in primary care as well as those from hospitals educate themselves in the field of prevention and prophylactic check-ups and are knowledgeable about legislation applicable to prophylactic check-ups.

An Evaluation on the Effects of Check-In/Check-Out with School-aged Children Residing in a Mental Health Treatment Facility

Stuart, Crystal Ann 01 January 2013 (has links)
School-Wide Positive Behavior Interventions and Support (SWPBIS) is an evidence- based application of Applied Behavior Analysis (ABA) to address and prevent problem behaviors from occurring, promote pro-social behaviors, and create a positive learning environment for all students. There are many secondary interventions that have been utilized within the framework of SWPBIS that have high success rates. However, the research conducted on the use of Check-In/Check-Out (CICO), a secondary intervention, has focused its attention more on its effectiveness in public elementary schools. There is a lack of research evaluating the effectiveness of CICO in alternative school settings. This study provides an extension to the literature by examining the effects of the CICO program with school-aged children residing in a mental health treatment facility. Using a concurrent multiple baseline across participants design, students were exposed to a CICO intervention strategy in which problem behaviors were targeted for reduction and academic engagement was targeted for acquisition. All three students showed substantial decreases in problem behavior and increases in academic engagement when the CICO intervention was in place.

Välbefinnande och Kognitiv Prestation : En experimentell studie om positiv sinnesstämning främjar kreativitet och flexibelt tänkande / Positive affect and cognitive performance : An experimental study exploring if positive affect promotes creativity and flexible thinking

Mariannesdotter, Joline, Sandgren, Oskar January 2014 (has links)
The purpose of the study was to investigate, through an experiment, if positive mood promotes creativity and flexible thinking. Participants were a total of 93 college students. The main hypothesis was that subjects induced with positive mood would perform better than subjects induced with negative mood, at a test reflecting creativity. To further explore the implications of priming (subliminal manipulated moods), a neutral control group was included. The cognitive test used in the study was Duncker´s The Candle Problem, a test which aims to get the subjects to apply flexible and creative thinking. The priming methods applied in the study was music and video clips. To measure the participant’s subjective mood a self-report scale, Mood Adjective Check List (MACL), was included as a successful manipulation control. The result showed a clear relationship between positive and negative priming, implying that subjects induced with positive mood performed significantly better than subjects induced with negative mood. There was no significant relationship between the groups induced with neutral and negative mood. / Syftet med studien var att genom ett experiment utforska om positiv sinnesstämning främjar kreativitet och flexibelt tänkande. Deltagarna i experimentet var totalt 93 studenter. Den huvudsakliga hypotesen var att deltagare inducerade till positivt känslotillstånd skulle prestera bättre än deltagare inducerade till negativt känslotillstånd, på ett kreativitetsreflekterande test. För att närmare undersöka påverkan av priming (subliminalt manipulerade känslotillstånd) inkluderades även en neutral kontrollgrupp. Testet som användes var Dunckers The Candle Problem. Syftet med testet var att få deltagarna att tillämpa flexibelt och kreativt tänkande. Priming-metoden som användes i experimentet bestod av musik och filmklipp. För att mäta deltagarnas subjektiva känslotillstånd tillämpades formuläret Mood Adjective Check List (MACL) som en framgångsrik manipulationskontroll. Ur resultatet utlästes en tydlig relation mellan positiv och negativ priming, att deltagare som fått positiv priming klarade testet signifikant bättre än deltagare med negativ priming. Mellan grupperna som inducerats med neutral och negativ sinnesstämning upptäcktes dock ingen signifikant relation.

Altering a Secondary Tier Intervention to Examine the Effects of Negative Reinforcement Contingencies on Elementary School Students

Swift, Stevie-Marie 01 January 2012 (has links)
Problem behaviors in the school setting have become more frequent as well as challenging for teachers and faculty to decrease while attempting to help their students attain their academic goals. Within the last decade, school-wide positive behavior support (SWPBS) has become more widespread as an evidence-based practice within the school system. SWPBS uses a multi-tiered support structure in order to affect behavior change across an entire school population. Several common secondary interventions have been utilized with high success rates. However, the research conducted thus far using the Check-In/Check-Out (CICO) program, a secondary intervention, has shown a lesser degree of success in behavior change with those students whose problem behavior is maintained by negative reinforcement or escape from aversive tasks. The current study examined the effects of the CICO program, adapted to address negative reinforcement contingencies. Using a multiple baseline across participants design, students in this study were exposed to a modified CICO intervention strategy in which problem behaviors, specifically related to the escape function as determined by a routine analysis, were targeted for reduction while academic engagement were targeted for acquisition. Results provided reductions in problem behaviors and an overall increase in academic engagement across participants with teacher implementers indicating the modified CICO program as feasible and acceptable. Implications for future research are discussed.

The methodology that was used is the data collection in the field of measuring thickness of the paint protection of apparent metal structures and photographic record of the problems of works, such as pathological manifestations of steel, paint, water accumulation sites etc. With the obtained data, the spreadsheet will be filled, depending on the model suggested by Mortari, 2008. In completing the Check list, it is easier to diagnose the structure, mainly because the diagnosis is last. / Recentemente têm-se percebido que alguns edifícios construídos em estruturas de aço na Cidade de Goiânia, vêm mostrando um processo progressivo de corrosão em seus sistemas estruturais, e em parte, como por exemplo: treliças, vigas, pilares etc. Tal sucessão foi percebida visualmente, devido às condições de agressividades ligadas primordialmente ao microambiente interno das edificações, chuva e fezes de animais. A Metodologia que foi empregada é o levantamento dos dados em campo medição da espessura da tinta de proteção das estruturas metálicas aparentes e com registro fotográfico dos problemas das obras, tais como, manifestações patológicas do aço, pintura, locais de acumulo de água etc. Com os dados obtidos, será preenchida a planilha, conforme o modelo sugerido por MORTARI, 2008. Com preenchimento do Check list, fica mais fácil fazer o diagnóstico da estrutura, principalmente por que o diagnóstico está no final.

Maintenance scheduling in the electricity industry : a particular focus on a problem rising in the onshore wind industry / Planification de la maintenance d’équipements de production d’électricité : une attention particulière portée sur un problème de l’industrie éolienne terrestre

Froger, Aurélien 14 December 2016 (has links)
L’optimisation de la planification de la maintenance des équipements de production d’électricité est une question importante pour éviter des temps d’arrêt inutiles et des coûts opérationnels excessifs. Dans cette thèse, nous présentons une classification multidimensionnelle des études de Recherche Opérationnelle portant sur ce sujet. Le secteur des énergies renouvelables étant en pleine expansion, nous présentons et discutons ensuite d’un problème de maintenance de parcs éoliens terrestres. Le problème est traité sur un horizon à court terme et l’objectif est de construire un planning de maintenance qui maximise le revenu lié à production d’électricité des éoliennes tout en prenant en compte des prévisions de vent et en gérant l’affectation de techniciens. Nous présentons plusieurs modélisations du problème basées sur la programmation linéaire. Nous décrivons aussi une recherche à grands voisinages basée sur la programmation par contraintes.Cette méthode heuristique donne des résultats probants.Nous résolvons ensuite le problème avec une approche exacte basée sur une décomposition du problème. Dans cette méthode, nous construisons successivement des plannings de maintenance optimisés et rejetons, à l’aide de coupes spécifiques, ceux pour lesquels la disponibilité des techniciens est insuffisante. Les résultats suggèrent que cette méthode est la mieux adaptée pour ce problème. Enfin, pour prendre en compte l’incertitude inhérente à la prévision de vitesses de vent, nous proposons une approche robuste dans laquelle nous prenons des décisions garantissant la réalisabilité du planning de maintenance et le meilleur revenu pour les pires scénarios de vent. / Efficiently scheduling maintenance operations of generating units is key to prevent unnecessary downtime and excessive operational costs. In this work, we first present a multidimensional classification of the body of work dealing with the optimization of the maintenance scheduling in the operations research literature. Motivated by the recent emergence of the renewable energy sector as an Environmental priority to produce low-carbon power electricity, we introduce and discuss a challenging Maintenance scheduling problem rising in the onshore wind industry. Addressing the problem on a short-term horizon, the objective is to find a maintenance plan that maximizes the revenue generated by the electricity production of the turbines while taking into account wind predictions, multiple task execution modes, and technician-to-task assignment constraints. We start by presenting several integer linear Programming formulations of the problem. We then describe a constraint programming-based large neighborhood search which proves to be an efficient heuristic solution method. We then design an exact branch-and-check approach based on a decomposition of the problem. In this method, we successively build maintenance plans while discarding – using problem-specific cuts – those that cannot be performed by the technicians. The results suggest that this method is the best suited to the problem. To tackle the Inherent uncertainty on the wind speed, we also propose a robust approach in which we aim to take risk-averse decisions regarding the revenue associated with the maintenance plan and its feasibility.

Ex vivo and in vitro evaluation of the influence of the inhaler device and formulation on lung deposition of budesonide

Aloum, Fatima, Al Ayoub, Yuosef, Mohammad, Mohammad A., Obeed, Muthana, Paluch, Krzysztof J., Assi, Khaled H. 10 August 2020 (has links)
Yes / Two different types of dry powder inhalers (Easyhaler® and RS01®) were used in this work to evaluate the ex vivo and in vitro performance of a budesonide inhaled formulation with recrystallised mannitol, commercial DPI-grade mannitol, or lactose. The aerodynamic performance of the budesonide formulation with recrystallised mannitol was superior when RS01® was used (FPF = 45.8%) compared to Easyhaler® (FPF = 14%). However, the aerodynamic profile was very poor in both devices when commercial mannitol was used. Interestingly, the aerosol performance of the marketed budesonide formulation significantly improved when RS01® was used compared to Easyhaler® (the original device for the formulation). Due to the significant increases in the surface energy of the commercial mannitol formulation, the aerodynamic performance of the formulation was very poor. This work demonstrates the impact of inhaler devices on the performance of inhaled formulations and considers the particle surface energy during formulation development.
