An Evaluation Protocol for Selection of Educational Technologies for Students with Developmental Disabilities: A Demonstration Study Using iPad Apps

Mainstream technologies are widely being employed in inclusive and special education classrooms to accommodate the learning needs of students. As the evidence of their effectiveness evolves, educators and school-based therapists need tools and documentable strategies for their implementation. This research presents an evaluation protocol to guide the selection of technologies for special education needs and demonstrates its application with iPad-based learning applications for students with developmental disabilities (DD). The learning engagement of six students with DD was compared using a single-subject design when using a computer, an iPad app “chosen” through the protocol and a “random” app. A blinded reviewer observed and rated student engagement in all three learning conditions. Analysis of data indicated that three students engaged better in learning with the chosen app than with the computer and a popular random app. The engagement of five students declined when the random app was implemented. The protocol demonstrates merit in systematic selection of educational technology for students with DD.
Consumers’ Stock Preferences Beyond Expected Financial Returns: The Influence of Product and Brand Evaluations

Purpose: The purpose of the article is to examine the links between individual investors’ subjective evaluations of certain companies’ products and brands, on one hand, and their willingness and decisions to invest in those companies’ stocks, on the other. The authors challenge the traditional assumption that individuals would make stock investment decisions purely on the basis of expected financial returns and risks.Design/methodology/approach: Survey data was collected from 293 individuals who invest in the stock market of a European country and analyzed with PLS path modeling.Findings: In the clear majority of the consumers’ stock investment decisions that were analyzed, the consumers exhibited some willingness to invest in a chosen stock beyond its expected financial returns/risk. Two variables are found to elicit willingness to invest in a company’s stock beyond its financial returns: (1) the personal relevance that the individual attaches to domains (activities or areas of interest; ideas or ideals) supported or represented by the company's products and (2) the individual’s affective evaluation of the company's product brand. Research limitations/implications: Replicating the study with different companies from different industries and with consumers from different countries will be important. Overcoming a potential retrospection bias in the reported study is also a task for further research.Practical implications: The findings provide insights that can serve segmentation, targeting, and positioning when it comes to marketing a company in the stock market so as to attract investors. Originality/value: The article provides new evidence on the influence of product and brand evaluations in consumers’ stock investment decisions – suggesting that positive product evaluations elicit extra willingness to invest in a company’s stock, over and beyond its financial returns.
Lead-contaminated house dust and urban children's blood lead levels.

OBJECTIVES This study assessed the relationship between lead-contaminated house dust and urban children's blood lead levels. METHODS A random-sample survey was used to identify and enroll 205 children, 12 to 31 months of age, who had resided in the same house since at least 6 months of age. Children's blood and household dust, water, soil, and paint were analyzed for lead, and interviews were conducted to ascertain risk factors for elevated blood lead (> or = 10 micrograms/dL). RESULTS Children's mean blood lead level was 7.7 micrograms/dL. In addition to dust lead loading (micrograms of lead per square foot), independent predictors of children's blood lead were Black race, soil lead levels, ingestion of soil or dirt, lead content and condition of painted surfaces, and water lead levels. For dust lead standards of 5 micrograms/sq ft, 20 micrograms/sq ft, and 40 micrograms/sq ft on noncarpeted floors, the estimated percentages of children having blood lead levels at or above 10 micrograms/dL were 4%, 15%, and 20%, respectively, after adjusting for other significant covariates. CONCLUSIONS Lead-contaminated house dust is a significant contributor to lead intake among urban children who have low-level elevations in blood lead. A substantial proportion of children may have blood lead levels of at least 10 micrograms/dL at dust lead levels considerably lower than current standards.

Job Satisfaction: Linking Perceived Organizational Support, Organizational Justice with Work Outcomes in China

This study develops and tests a full mediation model that examines the mediating role of job satisfaction in the Chinese context, based on a survey of 424 employees in three small and medium sized enterprises. Data analysis shows a good fit with the full mediation and all four classes of antecedents (i.e., perceived organizational support, procedural, distributive, and interactional justice). Particularly, procedural justice contributes to the prediction of satisfaction. Job satisfaction is also shown to mediate most antecedentconsequence relationships, except the two between perceived organizational support (POS)—turnover and procedural justice—consequences. Furthermore, there are only four direct links, including POS to citizenship behaviors directed at individuals, distributive justice to turnover intention, interactional justice to citizenship behaviors directed at organizations and turnover. These direct links suggest that job satisfaction does not fully mediate the relationships.

Identification and Analysis of Moderator Variables

Although the concept of moderator variables has been used extensively in marketing-related studies, much confusion persists as to how they are defined and identified. To alleviate this confusion, the authors present a typology of moderator variables with a framework for identifying their presence and type. Simulated data are used to illustrate and validate the proposed framework.
How leadership for an ICT reform is distributed within a school

Purpose – The purpose of this paper is to examine the process of information communication technology (ICT) reform in a government school in Singapore. The focus is on the distributed leadership actions performed by various individuals, and how the multiple leaders and their leadership practices interacted with one another.Design/methodology/approach – A naturalistic inquiry approach was adopted, involving the case study of a school in the process of implementing an instructional reform involving the use of ICT.Findings – It was found that distributed leadership for ICT implementation requires a combination of transformational leadership and instructional leadership to develop teachers’ capacity to enhance their instruction with ICT, emotional leadership to support teachers’ effort to change, and strategic management of resources to sustain teachers’ change efforts. Transformational leadership is performed mainly by senior management (SM). Instructional leadership is performed mainly by middle management .
Toxoplasma gondii peptide ligands open the gate of the HLA class I binding groove

HLA class I presentation of pathogen-derived peptide ligands is essential for CD8+ T-cell recognition of Toxoplasma gondii infected cells. Currently, little data exist pertaining to peptides that are presented after T. gondii infection. Herein we purify HLA-A*02:01 complexes from T. gondii infected cells and characterize the peptide ligands using LCMS. We identify 195 T. gondii encoded ligands originating from both secreted and cytoplasmic proteins. Surprisingly, T. gondii ligands are significantly longer than uninfected host ligands, and these longer pathogen-derived peptides maintain a canonical N-terminal binding core yet exhibit a C-terminal extension of 1–30 amino acids. Structural analysis demonstrates that binding of extended peptides opens the HLA class I F’ pocket, allowing the C-terminal extension to protrude through one end of the binding groove. In summary, we demonstrate that unrealized structural flexibility makes MHC class I receptive to parasite-derived ligands that exhibit unique C-terminal peptide extensions.

Genetic susceptibility in childhood acute leukaemias: a systematic review

Acute leukaemias (AL) correspond to 25–35% of all cancer cases in children. The aetiology is still sheltered, although several factors are implicated in causality of AL subtypes. Childhood acute leukaemias are associated with genetic syndromes (5%) and ionising radiation as risk factors. Somatic genomic alterations occur during fetal life and are initiating events to childhood leukaemia. Genetic susceptibility has been explored as a risk factor, since environmental exposure of the child to xenobiotics, direct or indirectly, can contribute to the accumulation of somatic mutations. Hence, a systematic review was conducted in order to understand the association between gene polymorphisms and childhood leukaemia risk. The search was performed in the electronic databases PubMed, Lilacs, and Scielo, selecting articles published between 1995 and 2013. This review included 90 case-control publications, which were classified into four groups: xenobiotic system (n = 50), DNA repair (n = 16), regulatory genes (n = 15), and genome wide association studies (GWAS) (n = 9). We observed that the most frequently investigated genes were: NQO1, GSTM1, GSTT1, GSTP1, CYP1A1, NAT2, CYP2D6, CYP2E1, MDR1 (ABCB1), XRCC1, ARID5B, and IKZF1. The collected evidence suggests that genetic polymorphisms in CYP2E1, GSTM1, NQO1, NAT2, MDR1, and XRCC1 are capable of modulating leukaemia risk, mainly when associated with environmental exposures, such as domestic pesticides and insecticides, smoking, trihalomethanes, alcohol consumption, and x-rays. More recently, genome wide association studies identified significant associations between genetic polymorphisms in ARID5B e IKZF1 and acute lymphoblastic leukaemia, but only a few studies have replicated these results until now. In conclusion, genetic susceptibility contributes to the risk of childhood leukaemia through the effects of gene–gene and gene–environment interactions.
Social Attachment and Juvenile Attitudes toward the Police in China

Objectives: The purpose of this study is to examine the correlates of juvenile attitudes toward the police in the Chinese setting. It borrows from the prevailing criminological wisdom developed in the West and Confucian philosophical doctrines to shed light on how attachment to social institutions helps explain variation in juvenile sentiments of the police. Method: The data were collected from a sample of 2,679 high school students in a southwestern Chinese city. A second-order latent variable labeled social attachment is constructed and comprised of three lower order factors representing family attachment, neighborhood attachment, and school attachment. Traditional demographic background, victimization, and contact with the police variables commonly used in U.S. studies are included in the analysis. Structural equation modeling is employed to test hypothesized relationships among explanatory variables and juvenile attitudes toward the police. Results: The findings suggest that the higher order factor social attachment is the most robust predictor of juvenile evaluations of the police in China. Other commonly used demographic, socioeconomic, and police contact factors show limited utility. Conclusion: The findings lend support to propositions derived from the Western criminological theories and the eastern philosophical doctrine to a major extent. Both confirmations of expected findings and noteworthy surprises are discussed.
The Effects of Frequency of Testing on College Students in a Principles of Marketing Course

This study was designed to determine if college students perform differently when they are tested more frequently than less frequently. The purpose of this research study was: (a) to determine if there is a difference in achievement between students given weekly tests (experimental group) and students given monthly tests (control group), (b) to determine if there is a difference in knowledge retention between students given weekly tests and students given monthly tests, and (c) to determine if there is a difference in time spent studying between students given weekly tests and students given monthly tests. The research design used was a true experimental form of the posttest-only with control technique. The participants were 109 students taking Principles of Marketing at Concord College in Athens, West Virginia. Fifty were enrolled in the fall of 1996, and the study was replicated with 59 students who were enrolled in the spring of 1997. Half of each class (fall and spring) was randomly assigned to weekly testing and the other halves were assigned to monthly testing. The weekly and monthly groups were taught simultaneously by the researcher both semesters. To test for differences in achievement between the weekly group and the monthly group, the mean test scores were compared at 80-question intervals. To test for differences in knowledge retention between the weekly group and the monthly group, the mean final exam scores were compared. To test for differences in hours spent studying between the weekly group and the monthly group, the means from the self-reported study hours surveys were compared at 80-question intervals. Based on the results of analysis of covariance, the research showed a significant difference in achievement between the weekly and the monthly groups in favor of the weekly group ( p = .007). However, the difference between the weekly and monthly group final exam scores was not significant ( p = .553), and the difference between the weekly and monthly groups' self-reported study hours was also not significant ( p = .231).
Regular physical activity has differential association with reduced obesity among diverse youth in the United States

This study examined whether daily or almost daily lower-intensity physical activity was associated with reduced obesity, among 4824 African American, Hispanic, and White youth assessed in fifth and seventh grades. Regular lower-intensity physical activity was associated with reduced obesity only among Hispanic and White males and only in seventh grade, and not among youth in fifth grade, females, or African American males or females. Findings from this study suggest that the reduced obesity risk generally attributed to physical activity may not be consistent across racial/ethnic and gender groups of early adolescents.
An investigation into the impact of vacation travel on the tourist

This paper explored the impact of vacation travel on the ‘self’ using a questionnaire survey and interviews. Vacation travel emerged as a form of learning about the self, a journey of self-discovery rather than self-recovery. Travel impacts are predominantly self-centered, producing changes that provide opportunities for personal growth. Experiences leading to these changes are mainly influenced by interactions with the ‘other’. Importantly, no significant association was found between personality type and being impacted, and no difference was found between a pleasurable and a miserable experience and being impacted. Both findings offer a contribution to knowledge and a platform for further research.
Employment and Utilization of Paraeducators in Inclusive Settings

The study, undertaken in two New England states using quantitative and qualitative methodologies, investigated paraeducators' experiences in inclusive educational settings, including administrative policies, job responsibilities, training, retention, and relationships with members of the school community. Findings emphasized the need for more training for paraeducators and the importance of relationships within the educational community. We conclude with recommendations for policymakers, administrators, teachers, institutions of higher education, and paraeducators to create effective inclusive educational programs.
Führen selbstgesteuerte Arbeitszeiten zu einer Ausweitung der Arbeitsstunden? Eine Längsschnittanalyse auf der Basis des Sozio-oekonomischen Panels

Selbstgesteuerte Arbeitszeiten sind inzwischen weit verbreitet. Es gibt bereits empirische Evidenz fur die Vermutung, dass selbstgesteuerte Arbeitszeiten, so wie sie derzeit haufig praktiziert werden, zu einer Ausweitung der Arbeitsstunden fuhren. Eine alternative Erklarung dieser Ausweitung ware eine systematische Selektion in selbstgesteuerte Arbeitszeiten entlang einer personlichen Tendenz zu Mehrarbeit. In dieser Studie werden zum ersten Mal deutsche Langsschnittdaten aus dem Sozio-oekonomischen Panel (SOEP) herangezogen, die es gestatten, diese alternative Erklarung in eine empirische Untersuchung einzubeziehen. Untersucht werden drei Indikatoren der Arbeitsextensivierung: die uber die vertraglich vereinbarte Arbeitszeit hinausgehenden Stunden, unentgoltene Uberstunden und individuelle Uberbeschaftigung. Auch bei statistischer Kontrolle der Fuhrungsverantwortung sprechen die Ergebnisse fur eine Arbeitsextensivierung bei unregulierter Selbststeuerung und (unter einigen methodischen Vorbehalten) gegen eine Arbeitsextensivierung bei regulierter Selbststeuerung.
A critical review of the eyes test as a measure of social‐cognitive impairment

Sensitivity to subtle cues regarding the emotions that others are experiencing is vital for effective interactions in social situations. The “Eyes Test” has been proposed, and utilized, as a measure of mild social impairment amongst adults. In this paper we consider the nature of this impairment and identify some limitations in the use of the Eyes Test as a measure of perceiver sensitivity to the psychological state of others. In addition, 25 participants completed the “Eyes Test” in the absence of the stimulus photograph. For over half of the items, participants selected the correct item. Implications for the Eyes Test and measurement of social impairment are considered. In summary, we advocate that future tests of social impairment use targets for which the affective state is known, use objective accuracy criterion, bear in mind the differentiation between genuine and posed expressions of emotion, and consider of the impact of contextual factors.
Efficacy of double gloving technique in major and minor oral surgical procedures: A prospective study

Background: A prospective analysis was carried out over a 1-year period to assess gloves used during 100 major and 100 minor oral surgical procedures to test for efficacy of double gloving in oral surgical procedures. Purpose: The purpose of this study was to assess the efficacy of double gloving technique in preventing cross infection in both major and minor oral surgical procedures. Materials and Methods: Gloves used during 100 major and 100 minor oral surgical procedures were analyzed to check for glove perforations and skin punctures. 100 sterile gloves were tested as control. Statistical Analysis Used: Chi-square test was used to determine whether there was any difference between the expected and observed values in various categories. Results: A higher number of glove perforations was seen in minor oral surgical procedures compared with major surgeries, dominant hand compared with the nondominant, outer gloves compared with the inner, in procedures which took a longer duration of time to complete, in procedures involving wiring and in the index finger followed by the thumb and the palm. Conclusion: Double gloving technique using sterile gloves can be used as an effective means of infection control for all major and minor surgical procedures, especially high-risk procedures involving patients who maybe suffering from or carriers of blood-borne infections.
Obesity, proteinuria and progression of renal failure

Purpose of reviewRecent studies have reported an alarming increase in the incidence of obesity-related glomerulopathy, in a context of a worldwide spread of obesity. Recent findingsSeveral epidemiological investigations have confirmed that obesity is a significant risk factor for the appearance of proteinuria and end-stage renal disease in a normal population. Obesity-induced hemodynamic changes and glomerular deposition of lipids (partly mediated by sterol regulatory element-binding proteins) play an important role in the pathogenesis of obesity-related renal disease. In addition, the renin-angiotensin-aldosterone system is markedly activated in obesity, adipocytes being an important source of these hormones. Weight loss induces a marked reduction in all renin-angiotensin-aldosterone system components. Patients with reduced renal mass of any origin appeared to be particularly susceptible to the detrimental influence of obesity: body mass index was the most important risk factor for the development of proteinuria and renal insufficiency in patients with unilateral renal agenesis, unilateral nephrectomy and remnant kidneys. Weight loss induces a very important reduction in proteinuria in chronic proteinuric nephropathies of different etiologies. SummaryPrevention and treatment of obesity should be a first-line objective in the therapeutic approach of patients with diabetic and nondiabetic chronic renal diseases.
