What people do with digital multimedia broadcasting? Path analysis of structural equation modelling

Drawing from the uses and gratifications theory, this study explores the influences of informativeness, entertainment and interactivity on the Digital Multimedia Broadcasting (DMB) user dimensions such as attitude, usage, and satisfaction. Particularly, usage and satisfaction are explored as the consequences of attitude towards DMB, while informativeness, entertainment and interactivity are the antecedents of attitude towards DMB. This relational model was tested with a Structural Equation Modelling (SEM) approach. SEM results indicated that the uses and gratifications theory explains users' attitudes towards DMB. DMB users who perceive it as entertaining and informative generally show a positive attitude towards DMB. In addition, the interactivity of DMB has a significant relation with the users' positive attitudes towards DMB. Finally, this study found that DMB users with a positive attitude towards DMB watch its content more often and feel more satisfied.
Guided School Visits to Natural History Museums in Israel: Teachers' Roles

Museums are favorite and respected resources for learning worldwide. In Israel, there are two relatively large science centers and a number of small natural history museums that are visited by thousands of students. Unlike other countries, studying museum visits in Israel only emerges in the last few years. The study focused on the roles and perceptions of teachers, who visited four natural history museums with their classes. The study followed previous studies that aimed at understanding the role teachers play in class visits to museums (Griffin & Symington, 1997, Science Education, 81, 763–779; Cox-Petersen et al., 2003, Journal of Research in Science Teaching, 40, 200–218; Olsen, Cox-Petersen, & McComas, 2001, Journal of Science Teacher Education, 12, 155–173) and emphasized unique phenomena related to the Israeli system. None of the teachers interviewed for this study was an active facilitator, and in many cases the teachers had no idea regarding the field trip program and rationale. Our main findings support previous studies that indicated that teachers are hardly involved in planning and enacting the museum visit. An issue of concern, which came up in this study, is the tendency of Israeli schools to use subcontractor companies that plan and make all the museum arrangements. Unlike the common patterns described in the paper, a case study of unique teacher's function is presented as well. © 2005 Wiley Periodicals, Inc. Sci Ed89:920–935, 2005
Reduced Macular Vascular Density in Myopic Eyes

Background: Morphological changes of the vasculature system in patients with myopia have been observed by Doppler ultrasound and fundus fluorescein angiography (FFA); however, these studies have limitations. Doppler ultrasound provides low-resolution images which are mainly obtained from visualized large vessels, and FFA is an invasive examination. Optic coherence tomography (OCT) angiography is a noninvasive, high-resolution measurement for vascular density. The purpose of this study was to investigate the change of vascular density in myopic eyes using OCT angiography. Methods: This cross-sectional study includes a total of 91 eyes from 47 participants including control, moderate, and high myopia that were evaluated by OCT angiography. Patients with myopia were recruited from the Refractive Department, Shenzhen Aier Eye Hospital, from August 5, 2015 to April 1, 2016. Emmetropic eyes were from healthy volunteers. The vascular density at macula and optic disc regions, ganglion cell complex (GCC) thickness, and retinal nerve fiber layer (RNFL) thickness were measured. Their relationships with axial length (AL) and refractive error were analyzed. One-way analysis of variance (ANOVA), Pearson's correlation, and generalized estimating equation were used for statistical analysis. Results: Both superficial and deep macular vascular density were highest in control (25.64% ± 3.76% and 37.12% ± 3.66%, respectively), then in moderate myopia (21.15% ± 5.33% and 35.35% ± 5.50%, respectively), and lowest in high myopia group (19.64% ± 3.87% and 32.81% ± 6.29%, respectively) (F = 13.74 and 4.57, respectively; both P < 0.001). Both superficial (&bgr; = −0.850 and 0.460, respectively) and deep (&bgr; = −0.766 and 0.396, respectively) macular vascular density were associated with AL and spherical equivalent (all P < 0.001). Superficial macular vascular density was associated with GCC thickness (&bgr; = 0.244, P = 0.040), independent of spherical equivalent. The vascular density in optic disc region had no difference among the three groups, and it was not associated with AL, spherical equivalent, or RNFL thickness. Conclusion: Our results suggested that with the increase of myopia, the vascular density decreased in macular region, but not in optic disc region.
Space-to-time mappings and temporal concepts

Abstract Most research on metaphors that construe time as motion (motion metaphors of time) has focused on the question of whether it is the times or the person experiencing them (ego) that moves. This paper focuses on the equally important distinction between metaphors that locate times relative to ego (the ego-based metaphors Moving Ego and Moving Time) and a metaphor that locates times relative to other times (sequence is relative position on a path). Rather than a single abstract target domain TIME, these two kinds of temporal metaphor metaphorize different kinds of temporal concept—perspective-specific vs. perspective-neutral temporal concepts. Recognition of this distinction enhances the explanatory potential of conceptual metaphor theory (Lakoff and Johnson 1980). An example involves the interaction of deixis and the temporal reference crosslinguistically of vocabulary with the spatial meanings in-front and behind. More generally, this approach refines our ability to describe the temporal concepts involved in motion metaphors of time. Such temporal concepts are present not only in the target domains, but also in the source domains of motion metaphors of time, where we find space-to-time metonymy, which may play a role in motivating the metaphors. In order to distinguish such metonymy from metaphor, we need to characterize metaphor as a mapping across frames rather than domains.
Prevalence of sleep-related accidents among drivers in Saudi Arabia

INTRODUCTION: The prevalence of sleepy driving and sleep-related accidents (SRA) varies widely, and no data exist regarding the prevalence of sleepy driving in Saudi Arabia. Therefore, this study was designed to determine the prevalence and predictors of sleepy driving, near-misses, and SRA among drivers in Saudi Arabia. MATERIALS AND METHODS: A questionnaire was developed to assess sleep and driving in detail based on previously published data regarding sleepy driving. The questionnaire included 50 questions addressing socio-demographics, the Epworth Sleepiness Scale (ESS), driving items, and the Berlin Questionnaire. In total, 1,219 male drivers in public places were interviewed face-to-face. RESULTS: The included drivers had a mean age of 32.4 ± 11.7 years and displayed a mean ESS score of 7.2 ± 3.8. Among these drivers, 33.1% reported at least one near-miss accident caused by sleepiness. Among those who had actual accidents, 11.6% were attributed to sleepiness. In the past six months, drivers reported the following: 25.2% reported falling asleep at least once during, driving and 20.8% had to stop driving at least once because of severe sleepiness. Young age, feeling very sleepy during driving, and having at least one near-miss accident caused by sleepiness in the past six months were the only predictors of accidents. CONCLUSION: Sleepy driving is prevalent among male drivers in Saudi Arabia. Near-miss accidents caused by sleepiness are an important risk factor for car accidents and should be considered as a strong warning signal of future accidents.
Identifying Elements of Patient-Centered Care in Underserved Populations: A Qualitative Study of Patient Perspectives

Patient-centered care is an important goal in the delivery of healthcare. However, many patients do not engage in preventive medical care. In this pilot study, we conducted twenty in depth, semi-structured qualitative interviews at the University of Illinois at Chicago Health Sciences campus in a four month time frame. Many patients were underserved and underinsured, and we wanted to understand their experiences in the healthcare system. Using content analysis, several themes emerged from the interview data. Participants discussed the need for empathy and rapport with their providers. They identified provider behaviors that fostered a positive clinical relationship, including step-by step explanations of procedures, attention to body language and clinic atmosphere, and appropriate time management. Participants identified cost as the most common barrier to engaging in preventive care and discussed children and social support as motivating factors. A long-term relationship with a provider was an important motivator for preventive care, suggesting that the therapeutic alliance was essential to many patients. Conversely, many participants discussed a sense of dehumanization in the healthcare system, reporting that their life circumstances were overlooked, or that they were judged based on insurance status or ethnicity. We discuss implications for provider training and healthcare delivery, including the importance of patient-centered medical homes.

Hesitant Fuzzy Linguistic Term Sets for Decision Making

Dealing with uncertainty is always a challenging problem, and different tools have been proposed to deal with it. Recently, a new model that is based on hesitant fuzzy sets has been presented to manage situations in which experts hesitate between several values to assess an indicator, alternative, variable, etc. Hesitant fuzzy sets suit the modeling of quantitative settings; however, similar situations may occur in qualitative settings so that experts think of several possible linguistic values or richer expressions than a single term for an indicator, alternative, variable, etc. In this paper, the concept of a hesitant fuzzy linguistic term set is introduced to provide a linguistic and computational basis to increase the richness of linguistic elicitation based on the fuzzy linguistic approach and the use of context-free grammars by using comparative terms. Then, a multicriteria linguistic decision-making model is presented in which experts provide their assessments by eliciting linguistic expressions. This decision model manages such linguistic expressions by means of its representation using hesitant fuzzy linguistic term sets.
When the Nest Egg Cracks: Financial Consequences of Health Problems, Marital Status Changes, and Job Layoffs at Older Ages

The risk of falling into poor health, losing the ability to work or live independently, becoming widowed, and experiencing other negative events that threaten financial security increase with age. This report computes the incidence of these negative events at older ages and examines their impact on economic well-being. Over a 10-year period, more than three-quarters of adults age 51 to 61 at the beginning of the period experience job layoffs,widowhood, divorce, new health problems, or the onset of frailty among parents or in-laws. More than two-thirds of adults age 70 and older experience at least one negative shock over a nine-year period. Incidence rates are even higher at the household level for married people, who face the added risk that their spouses could develop health problems or lose their jobs. Financial consequences are especially serious for older adults who develop work disabilities or long-term care needs, or who become unemployed.
To Catch a Liar: Challenges for Research in Lie Detection Training

Can we train people to detect deception? It is the contention of this article that communication scholars should learn how to train law enforcement professionals on how to detect high stake lies, like those faced by police, judges, customs officials, immigration officials, and so forth. It is proposed that in order to know whether we can train or should bother to train people to detect deception, each training study must meet 6 challenges: (1) relevance, (2) high stakes, (3) proper training, (4) proper testing, (5) generalizability across situations, and (6) generalizability over time. Our quantitative review of the literature suggests that training does significantly raise lie detection accuracy rates. Meta-analytic findings indicate a mean effect size of r = . 20 across 20 (11 published studies) paired comparisons of lie detection training versus the control group (i.e., those without some type of training). It should be noted that the majority of the studies that attempt to train lie detectors fall short on many of the above challenges. Current research in lie detection training may actually underestimate the ability to train lie detectors due to the stimulus materials employed in most experiments.
Transitioning to Adult Mental Health Services

Longitudinal studies have demonstrated that youth with mental health problems tend to have poor outcomes in adulthood. Moreover, many young adults do not make the transition from child- to adult-focused care even when they acknowledge their need for support. This study is an investigation of the needs and experiences of late adolescents with emotional and/or behavioral problems who accessed mental health services at a local child and adolescent clinic. In general, participants did not appear ready for an institutional transition. Adolescents disclosed their fears, underscoring the importance of supportive relationships, and stated the negative expectations they had concerning adult-focused care. The implementation of clinical supports to increase adolescents’ mental health self-efficacy may promote successful service transitions.
The Effects of High School Course Taking and SAT Scores On College Major Selection

A survey study design was employed to examine the relationship between enrollment in computer and Advanced Placement courses during high school, SAT scores and subsequent selection of a STEM major in post-secondary education. Study data were collected through an online survey from a multi-school charter school system in which a variety of computer courses are offered to 9-12 grade students. The study showed that students' scores on the SAT reading section and, total composite score (reading + mathematics) had a statistically significant relationship with students' selection of a science, engineering, technology, and mathematics [STEM] major. Although there was not a statistically significant relationship between students' SAT mathematics scores, there was a pattern showing that students with higher SAT mathematics scores were more likely to choose a STEM major. We also found that there was a statistically significant relationship between the number of AP science courses and total number of AP courses taken by students and their selection of a STEM major. The final analysis revealed that there was no statistically significant difference between those who chose STEM majors and the number of computer courses taken.
Interaction and Uptake in Large Foreign Language Classrooms

Inteaction determines and affects the conditions of language acquisition especially in contexts where exposure to the target language is limited. This is believed to be successful only within the context of small classes (Chavez, 2009). This paper examines learners’ progress resulting from interaction in large classes. Using pre-, post-, and delayed post-test, results from two groups of participants (n=78 and 83) involved in the study do not show any significant difference at post- and delayed post-test. The study, therefore, rejects the argument that class size constrains interaction and instead argues that the durability of knowledge gained from interaction appears to have a stronger correlation with type of interaction, learners’ previous learning styles, proficiency, and the wider context of learning. The paper also argues that teacher-led interaction is not only possible with low proficiency, but could lead to outcomes which actually define the purpose for which language is learnt.
PSYCHIATRIC OUT-PATIENT IN A GENERAL HOSPITAL OF ADDIS ABABA DIAGNOSTIC AND SOCIODEMOGRAPHIC CHARACTERISTICS

SUMMARY Delivery of mental care in developing countries has been awfully inadequate. General hospital psychiatric units can play a significant role in providing care to the mentally ill as well as in training aspects of the health professionals. The problems of mental illness are practically same all over as has been highlighted in the paper which discusses the functioning and diagnostic and demographic data of such a unit in Ethiopia. The paper also compares the diagnostic data with that of an Indian and a British study.
Alcohol Withdrawal-Induced Seizure Susceptibility is Associated with an Upregulation of CaV1.3 Channels in the Rat Inferior Colliculus

Background: We previously reported increased current density through L-type voltage-gated Ca2+ (CaV1) channels in inferior colliculus (IC) neurons during alcohol withdrawal. However, the molecular correlate of this increased CaV1 current is currently unknown. Methods: Rats received three daily doses of ethanol every 8 hours for 4 consecutive days; control rats received vehicle. The IC was dissected at various time intervals following alcohol withdrawal, and the mRNA and protein levels of the CaV1.3 and CaV1.2 α1 subunits were measured. In separate experiments, rats were tested for their susceptibility to alcohol withdrawal–induced seizures (AWS) 3, 24, and 48 hours after alcohol withdrawal. Results: In the alcohol-treated group, AWS were observed 24 hours after withdrawal; no seizures were observed at 3 or 48 hours. No seizures were observed at any time in the control-treated rats. Compared to control-treated rats, the mRNA level of the CaV1.3 α1 subunit was increased 1.4-fold, 1.9-fold, and 1.3-fold at 3, 24, and 48 hours, respectively. In contrast, the mRNA level of the CaV1.2 α1 subunit increased 1.5-fold and 1.4-fold at 24 and 48 hours, respectively. At 24 hours, Western blot analyses revealed that the levels of the CaV1.3 and CaV1.2 α1 subunits increased by 52% and 32%, respectively, 24 hours after alcohol withdrawal. In contrast, the CaV1.2 and CaV1.3 α1 subunits were not altered at either 3 or 48 hours during alcohol withdrawal. Conclusions: Expression of the CaV1.3 α1 subunit increased in parallel with AWS development, suggesting that altered L-type CaV1.3 channel expression is an important feature of AWS pathogenesis.
Little mermaids and pro-sumers

In this article the authors explore the ways in which social media and social network sites (SNSs) are mediating the new urban environment. Many analyses of these technologies highlight the ways in which they are predicated on surveillance techniques and how the self is increasingly entwined within them. The authors examine the processes of surveillance, and the surveillant assemblage, and how the self interacts with these technologies to produce an authentic self in mediated urban spaces. They argue that SNS technologies privilege a version of the contemporary self, limiting choice to ‘pro-sumer’ activity, and a mandatory self-surveillance. Instead of constructing an open public sphere, these technologies operate to build a ‘second city’ of commodified urban space in which the recording of banal activities in an everyday setting is the authentic lived experience of people using this technology.
Laptops for teachers: practices and possibilities

The Laptops for Teachers scheme in New Zealand provides teachers whose schools opt into the scheme access to a laptop for their exclusive use. This paper reports on the findings of the three‐year evaluation of the impact of the laptops on secondary teachers’ work. The findings indicate that school leadership has been pivotal to the provision of the technological infrastructure and organisational support needed for teacher use of the laptops. Departmental leadership has been crucial in supporting teacher use of laptops for teaching and learning. Teachers described gains in expertise, indicating that they used the laptop for a range of purposes to support their teaching. These included lesson planning and preparation, and reporting. Where teachers had easy access to a laptop‐plus‐data projector they found that students responded to material that included images and up‐to‐date real‐world examples. Colleagues were identified as the main source of professional development for the use of the laptop for teaching purposes. The findings of the study suggest schools are advised to consider how to support teachers to work collaboratively to share expertise as a way of supporting and extending teacher use of laptops.
Risk factors and comorbidities in the preclinical stages of chronic obstructive pulmonary disease.

RATIONALE There is little information about comorbidities and their risk factors in the preclinical stages of chronic obstructive pulmonary disease (COPD). OBJECTIVES This study aims to investigate the prevalence of premorbid risk factors and comorbid diseases and its association with daily physical activity in subjects detected with COPD by spirometry screening. METHODS Sixty subjects with preclinical COPD (63 ± 6 yr; 68% [n = 41] male) were compared with 60 smoking control subjects (62 ± 7 yr; 70% [n = 42] male) and 60 never-smoking control subjects (62 ± 6 yr; 57% [n = 34] male). Comorbidities (cardiovascular, metabolic, and musculoskeletal disease) and daily physical activity (by multisensor activity monitor) were measured objectively. MEASUREMENTS AND MAIN RESULTS The prevalence of premorbid risk factors and comorbid diseases was significantly higher in preclinical COPD compared with age-matched never-smoking control subjects, but was similar to smoking control subjects not suffering from COPD. In preclinical COPD and smoking control subjects, the combination of cardiovascular disease and musculoskeletal disease was the most prevalent (15% [n = 9] and 12% [n = 7], respectively). In a multivariate logistic regression analysis, physical inactivity and smoking were found to be independent risk factors for having greater than or equal to two comorbidities. CONCLUSIONS Premorbid risk factors and comorbid diseases were more prevalent in the preclinical stages of COPD and smokers without COPD. Physical inactivity and smoking were more strongly associated with the presence of comorbidities compared with airflow obstruction. Clinical trial registered with www.clinicaltrials. gov (NCT 01314807).
