A number of randomization statistical procedures have been developed to analyze the results from single-case multiple-baseline intervention investigations. In a previous simulation study, comparisons of the various procedures revealed distinct differences among them in their ability to detect immediate abrupt intervention effects of moderate size, with some procedures (typically those with randomized intervention start points) exhibiting power that was both respectable and superior to other procedures (typically those with single fixed intervention start points). In Investigation 1 of the present follow-up simulation study, we found that when the same randomization-test procedures were applied to either delayed abrupt or immediate gradual intervention effects: (1) the powers of all of the procedures were severely diminished; and (2) in contrast to the previous study's results, the single fixed intervention start-point procedures generally outperformed those with randomized intervention start points. In Investigation 2 we additionally demonstrated that if researchers are able to successfully anticipate the specific alternative effect types, it is possible for them to formulate adjusted versions of the original randomization-test procedures that can recapture substantial proportions of the lost powers.

A third of youth in the United States are currently classified as overweight, which is impacted by the low rates of youth that meet daily physical activity recommendations. Engaging in physical activity contributes to healthy body weight and physical fitness, both of which have positive health consequences. Participating in physical activity not only aids in positive health outcomes, but research indicates that it also has a positive relationship with and effect on youths’ cognitive, academic, and behavioral outcomes. The majority of researchers conducting meta-analyses examining the effect of physical activity on youths’ cognitive, academic, and behavioral outcomes have excluded single-case design research from the data analyses. Excluding these types of designs from syntheses of the research may create an inaccurate account of the effect of physical activity on youths’ cognitive, academic, and behavioral outcomes. The current study addressed these issues by conducting a meta-analysis of single-case design studies over approximately the past 50 years to add to the current understanding of the effect of physical activity on youths’ cognitive, academic, and behavioral outcomes. Additionally, moderator analyses were conducted on numerous participant, intervention, and study characteristics that were deemed important, as indicated in the literature review. The effect size of physical activity on youths’ academic and behavioral outcomes was determined by utilizing hierarchical linear modeling of the included 81 time series from 15 single-case design studies. There were not enough data to calculate the effect size on youths’ cognitive outcomes. Significant effect sizes were found that indicate physical activity has an effect on increasing youths’ desirable behaviors (e.g.on task behavior and social skills) and decreasing youths’ undesirable behaviors (e.g. self stimulation, self-injurious behaviors, and off task behavior; ES = 1.83), as well as, increasing work completion, (ES = 2.01). No moderating effects were found other than the type of single case design moderated the effect on youths’ behavioral outcomes. The current study is important for decision makers in schools when deciding whether to increase or decrease particular students’ time spent in physical activity. Additionally, the results of the study are pertinent to other practitioners who work with youth, parents, and for youth themselves so that they can utilize physical activity interventions to help with appropriate behaviors and work completion.

In the past two decades, a need in forming strategic alliance has become increasingly important, especially for small companies. Likewise, airline alliances act as a vehicle for small carriers to obtain their superior position or to survive competition in a competitive international market where they do not appear to be a dominant player. In strategic alliances, the greater integration conveys greater benefits. However, the level of failure and success are varied among alliance members. This thesis was underpinned by the aim to conduct an in-depth study under the concept of organisational culture to reveal the key issues and barriers that appear to distort the ability of an organisation to foster success as well as to boost up its ability to obtain the benefits from the alliances to the maximum level.The empirical investigation employed a qualitative approach as a mechanism, driving this thesis through the process of research design, data collection, and data analysis. Using a single case study as a main technique, the case company of this thesis is Thai Airways. Data was collected through in-depth and semi-structured interviews. Data was analysed using thematic grouping and organised through NVIvo software.This thesis displayed the findings into two main themes. The first theme is associated with the activity to diagnose organisational culture, whereas the Competing Values Framework (CVF) was adopted as an initial framework. The main objectives are to develop a cultural profile for Thai Airways and to identify the key issues and barriers that distort the ability of Thai Airways to foster success. The key finding derived from this theme offered the identified problems and barriers derived from organisational culture. Using the Critical Success Factors (CSFs) method, the second theme is associated with the activity to identify the critical success factors for Thai Airways, deriving as a set of CSFs proposed to help enhance the ability of Thai Airways to obtain big firm's benefits. The outcome of this thesis could be considered as a new reference for the areas of organisational studies and the success of airlines, where the literature appears to be limited. More importantly, this thesis believed that the research journey offered an empirical experience reflecting a piece of organisational culture study in a non-Western context.

This study explored the use of animal-assisted therapy with students identified with a learning disability and limited reading success. Initially, reading progress was defined as the participants' comprehension rate obtained from an oral Informal Reading Inventory (IRI) passage. The nature of the Informal Reading Inventory requires the introduction of more difficult reading passages as the student's comprehension rate increases, potentially masking the overall effect of the intervention. Due to this factor and erratic student performance, which is a common characteristic of students with learning disabilities, obtaining consistent comprehension rates was difficult. Therefore, progress was defined only as total amount of time the student was engaged in reading under each condition. A reversal replication, single case design was implemented to determine the effects of reading to the therapy dog on the students' reading progress as measured by total amount of time read. The analysis indicated a statistically significant increase in the total amount of reading time as determined by the participants in the presence of the therapy dog. Positive student feedback about their experience reading with the therapy dog supported the effect of the intervention on reading progress.

Data breaches happen almost every day in the United States and, according to research, the majority of these breaches occur due to a lack of security with organizations' mobile devices. Although most of the security policies related to mobile devices currently in place may meet the guidelines required by law, they often fail to prevent a data breach caused by a mobile device. The main purpose of this qualitative single case study was to explore the strategies used by security managers to prevent data breaches caused by mobile devices. The study population consisted of security managers working for a government contractor located in the southeastern region of the United States. Ludwig von Bertalanffy's general systems theory was used as the conceptual framework of this study. The data collection process included interviews with organization security managers (n = 5) and company documents and procedures (n = 13) from the target organization related to mobile device security. Data from the interviews and organizational documents were coded using thematic analysis. Methodological triangulation of the data uncovered 4 major themes: information security policies and procedures, security awareness, technology management tools, and defense-in-depth. The implications for positive social change from this study include the potential to enhance the organizations' security policies, cultivate a better security awareness training program, and improve the organizations data protection strategies. In addition, this study outlines some strategies for preventing data breaches caused by mobile devices while still providing maximum benefit to its external and internal customers.

Bråk är inkörsporten till rationella tal och en god förståelse av bråk ligger till grund för den enskilda elevens fortsatta matematikutveckling. Yngre elever, i de tidiga skolåren, har ofta en intuitiv förståelse för enkla bråk, men glappet till den mer formella undervisningen är stort. Svårigheter att lära sig bråk är genomgående och ger långtgående konsekvenser. Det är därför av stor vikt att tidigt uppmärksamma och ge stöd till de elever som möter svårigheter inom detta område. Vi har replikerat en tidigare genomförd interventionsstudie med enskild intensivundervisning kring bråk genom explicit undervisning och CRA. Interventionen fokuserar på bråk som tal, där tallinjen spelar en avgörande roll, och består av nio lektionstillfällen. Syftet med studien har varit att bidra med kunskap om interventioner i matematik samt att undersöka vilken effekt ett interventionsprogram med enskild intensivundervisning har på elever i matematiksvårigheter i årskurs 5 och 6. Syftet har också varit att undersöka om elevernas relationer till matematikämnet kan förändras av interventionen.  Studien är en experimentell fallstudie med sex deltagare, där varje individ utgör sin egen kontroll. Data har samlats in i form av resultat på olika tester och skattningar, före, under och efter interventionen. Resultatet visar på en signifikant förbättring av elevernas kunskaper om bråk som tal efter genomförd intervention. Dessutom framkommer en spridningseffekt till området bråk som del av en helhet/antal, vilket tyder på en ökad konceptuell förståelse av bråk. Elevernas kunskaper kvarstår vid ett fördröjt eftertest, fem veckor efter avslutad intervention.  Den slutsats vi drar utifrån resultatet är att en kortare intervention på individnivå, om bråk som tal med tallinjen i fokus, kan ge stor effekt på elevernas kunskaper, som kvarstår över tid. Vi kan inte dra några generella slutsatser kring huruvida elevernas relationer till matematikämnet förändras av interventionen.

Nonsuicidal self-injury (NSSI; i.e., the deliberate destruction of one’s own bodily tissue without suicidal intent and for reasons not socially sanctioned) is prevalent and associated with clinically serious consequences. There is a need for evidence-based, stand-alone treatments for this behavior as it presents across the full range of psychiatric disorders. Developing time-efficient and cost-effective interventions for NSSI has proven difficult given that the core components of treatment remain largely unknown. The aim of this study was to examine the specific effects on NSSI of mindful emotion awareness training and cognitive reappraisal, two transdiagnostic treatment strategies that directly address the functional processes that often maintain self-injury (i.e., relief or escape from aversive thoughts or feelings). Using a counterbalanced, combined series (multiple baseline and phase change) single-case experimental design, the unique and combined impact of these two four-week interventions was evaluated among diagnostically heterogeneous, self-injuring adults (N = 10; mean age = 21.3, range = 18 to 30 years). Hypotheses were that each intervention would produce clinically meaningful reductions in NSSI; adding the alternative intervention would have additive benefit for those who did not respond to the initial intervention alone; and reductions in NSSI would be maintained over a four-week follow-up phase. Results showed that 8 of 10 participants demonstrated clinically meaningful reductions in NSSI by the follow-up phase; six participants responded to one intervention alone, whereas adding the alternative intervention was associated with additive benefit for two participants. Group-based analyses indicated a statistically significant effect of study phase on NSSI (p < .001), with fewer NSSI urges and acts occurring after the interventions were introduced. The interventions were also associated with moderate to large reductions in anxiety (d = 0.89 – 1.09), depression (d = 0.79 – 1.09), and interference caused by symptoms (d = 0.61), and with improvements in skills-based mechanisms: mindful emotion awareness (d = 1.44) and reappraisal (d = 1.30). The results suggest that increasing mindful emotion awareness and cognitive reappraisal may be two key therapeutic strategies for reducing NSSI. Transdiagnostic, emotion-focused interventions delivered in time-limited formats can serve as practical yet powerful treatment approaches, especially for lower-risk self-injuring individuals.
