Market Structure and Investment in the Mobile Industry

The impact of market structure, that is the number of firms and asymmetry, on investment is an important topic in the mobile industry. However, previous literature remains ambiguous about the direction of the relationship. This paper provides an empirical evidence of the impact of market structure on investment in the European mobile industry. The empirical assessment is based on a Salop model with vertical differentiation. Consistently with the prediction of this model, we find that both the number of operators and market share asymmetry have significant effects on investment. In symmetric markets, investment per operator falls with the number of operators, with larger effects for operators that lose market share more than the average. The industry investment rises with the number of operators in the short run, but eventually falls in the long run due to significant adjustment costs of investment in the mobile industry. These findings suggest that investment should be taken into account when analysing the welfare effects of market structure in the mobile industry.
Complaints of olfactory disorders: epidemiology, assessment and clinical implications

Purpose of reviewRecent studies illuminate the difficulties that patients with olfactory disorder face in daily life, which underlines the need to understand its prevalence, and to diagnose and treat these patients. The purpose of the present review is to characterize olfactory disorders and describe associated complaints, present recent insights into epidemiology, suggest procedures to assess these disorders, and discuss clinical implications. Recent findingsA compilation of previous and new studies of olfactory disorders suggests associated complaints of poor quality of life, depression, and various specific consequences. Epidemiological studies show that loss in odor sensitivity is common in both general and clinical populations, whereas dysosmia is less common in general populations but frequent in clinical populations. The most common etiologies are post-upper respiratory infection, nasal/sinus disease and head trauma. SummaryProcedures to diagnose olfactory disorders and to identify etiologies are available. Depending on etiology, certain types of treatment are often successful, such as endoscopic sinus surgery and corticosteroid administration in nasal/sinus disease. In post-upper respiratory infection and head trauma, spontaneous recovery is fairly high. In any case, it is advisable to counsel the patient with regards to strategies to cope with olfactory disorders.
Anaphylaxis in the emergency department: a paediatric perspective

Purpose of review Correct management of anaphylactic manifestations in the emergency department is crucial to prevent mortality and future episodes, in particular for paediatric patients. We make here recommendations based on a critical review of the evidence for the management of anaphylaxis in emergency department with particular emphasis on children. Recent findings Available information suggests that anaphylaxis must be promptly recognized keeping in mind the airway patency, breathing (ventilation and respiration), circulation and mental status and treated. The first treatment is epinephrine. After successful treatment of an anaphylactic episode, attention must be paid at prevention of early recurrences (biphasic anaphylaxis) and assessment of causes. Patients should not be discharged before prescribing self-injectable epinephrine and explain how and in under what circumstances it must be injected; giving an action plan to be communicated to their communities; inform the school about the possible occurrence of reactions and the appropriate avoidance and rescue measures; and consider the necessity of a Medic-Alert identification. Summary As gross differences have been described in the awareness of the disease and its management between allergists and nonallergists, allergists should interact with emergency doctors to improve education in this area.
Changes in anatomy instruction and USMLE performance: Empirical evidence on the absence of a relationship

Anatomy instruction has evolved over the past two decades as many medical schools have undergone various types of curricular reform. To provide empirical evidence about whether or not curricular changes impact the acquisition and retention of anatomy knowledge, this study investigated the effect of variation in gross anatomy course hours, curricular approach (stand‐alone versus integrated), and laboratory experience (dissection versus dissection and prosection) on USMLE Steps 1 and 2 Clinical Knowledge (CK) scores. Gross anatomy course directors at 54 United States schools provided information about their gross anatomy courses via an online survey (response rate of 42%). Survey responses were matched with USMLE scores for 6,411 examinees entering LCME‐accredited schools in 2007 and taking Step 1 for the first time in 2009. Regression analyses were conducted to examine relationships between gross anatomy instructional characteristics and USMLE performance. Step 1 total scores, Step 1 gross anatomy sub‐scores, and Step 2 CK scores were unrelated to instructional hours, controlling for MCAT scores. Examinees from schools with integrated curricula scored slightly lower on Steps 1 and 2 CK than those from stand‐alone courses (effect sizes of 2.1 and 1.9 on score scales with SDs of 22 and 20, respectively). Examinees with dissection and prosection experience performed slightly better on Step 2 CK than examinees in courses with dissection only laboratories (effect size of 1.2). Results suggest variation in course hours is unrelated to performance on Steps 1 and 2 CK. Although differences were observed in relation to curricular approach and laboratory experience, effect sizes were small. Anat Sci Educ 6: 3–10. © 2012 American Association of Anatomists.
The Role of Syllables in Anagram Solution: A Rasch Analysis

ABSTRACT Anagrams are frequently used by experimental psychologists interested in how the mental lexicon is organized. Until very recently, research has overlooked the importance of syllable structure in solving anagrams and assumed that solution difficulty was mainly due to frequency factors (e.g., bigram statistics). The present study uses Rasch analysis to demonstrate that the number of syllables is a very important factor influencing anagram solution difficulty for both good and poor problem solvers, with polysyllabic words being harder to solve. Furthermore, it suggests that syllable frequency may have an impact on solution times for polysyllabic words, with more frequent syllables being more difficult to solve. The study illustrates the advantages of Rasch analysis for reliable and unidimensional measurement of item difficulty.
Red Letters and Where They Are Going

Border intervention is a key element in Australia's biosecurity strategy. Mail articles are inspected, and those that are intercepted with biosecurity risk material are recorded, including the address to which the article was to be delivered. We used geo-location software to identify the delivery address of mail articles intercepted with biosecurity risk material from 2008-2011. We matched these addresses with demographic data that were recorded at a regional level from the Australian Bureau of Statistics 2011 Census. We used random forest statistical analyses to try to correlate various demographic variables at the regional level with the counts of seized mail articles. The analysis of the seizure counts against demographic characteristics suggests a high correlation between having higher numbers of university students that speak language A at home and containing the destination addresses for higher quantities of intercepted mail articles. This statistical pattern can be used to inform policy actions to try to reduce the rate at which mail articles that contain biosecurity risk material are sent to Australia.
Costs and Benefits in Item-Method Directed Forgetting: Differential Effects of Encoding and Retrieval

ABSTRACT This study examined how encoding and retrieval factors affected directed forgetting costs and benefits in an item-method procedure. Experiment 1 used a typical item-method procedure and revealed a levels-of-processing effect in overall recall. However, the deep encoding condition showed a smaller directed forgetting effect than the shallow encoding conditions. More importantly, “remember” (R) words were selectively rehearsed as indicated by greater recall from the primacy portion of the list and more apt to be recalled before “forget” (F) words. Experiment 2 showed that a deep encoding operation reduced directed forgetting costs and that directed forgetting benefits occurred only when R words were recalled before F words. These findings supported the hypotheses that encoding manipulation affected directed forgetting costs and that directed forgetting benefits were associated with output order bias. Results were discussed in terms of mechanisms that produce item-method directed forgetting.
Problem‐based learning in regional anatomy education at Peking University

Problem‐based learning (PBL) has been introduced to medical schools around the world and has increasingly become a popular pedagogical technique in Asian countries since 1990. Gross anatomy is a fundamental basic science course in virtually all medical training programs, and the methods used to teach it are under frequent scrutiny and revision. Students often struggle with the vast collection of new terms and complex relationships between structures that they must learn. To help students with this process, our department teaches separate systemic and regional anatomy courses, the latter in a PBL format. After three years of using PBL in our regional anatomy course, we have worked out a set of effective instructions that we would like to share with other medical schools. We report here evidence that our clinical PBL approach stimulates students' interest in learning and enhances anatomy education in a way that can foster better practices in our future medical work force.

Interventions to Improve the Implementation of Evidence Based Practices in Women Care

An important component of quality of care is the use of evidence-base d practices. Three studies from three different continents (Africa, Asia and Latin America) have reported the suboptimal use of evidence - based interventions in obstetric care, proving that despite scientific evidence and dissemination efforts, there are harmful and/or unnecessary procedures still used, while others that are beneficial are ignored. This illustrates the existing bridges and barriers between practice guidelines based on research findings and practitioners. A theoretical framework could help explain these barriers and possibly help target interventions to specific barriers. A review of existing literature shows that an intervention aimed to increase the use of evidence-base d practices should have the following components: increase birth attendant concern about the effectiveness of routine clinical practices, stimulate their desire to review the effectiveness of their practice, provide them with skills to perform evidence based clinical guidelines appraisal and development and establish mechanisms through key hospital leaders to implement the guidelines and sustain them over time.
Animate Objects are Detected More Frequently than Inanimate Objects in Inattentional Blindness Tasks Independently of Threat

ABSTRACT Inattentional blindness occurs when individuals are engaged in an attention-demanding task and fail to detect unexpected objects in their visual field. Two experiments examined whether certain unexpected objects are more easily detected than others. The unexpected objects were animate and threatening (e.g., snake), animate and nonthreatening (e.g., bird), inanimate and threatening (e.g., gun), or inanimate and nonthreatening (e.g., bed). Three hypotheses were tested: the snake detection hypothesis (snakes will be detected more frequently than all other objects), the animate monitoring hypothesis (animate objects will be detected more frequently than inanimate objects), and the threat superiority hypothesis (threatening objects will be detected more frequently than nonthreatening objects). Only the animate monitoring hypothesis was supported in both experiments. These results suggest that animate objects capture attention in the absence of task-relevant goals and that snakes do not show an advantage over other animate objects in inattentional blindness tasks.
Physiological testing of the high-performance athlete

The purpose of physiological testing (J.D. MacDougall and H.A. Wenger) what do tests measure? (H.J. Green) testing strength and power (D.G. Sale) testing aerobic power (J.S. Thoden) testing anaerobic power and capacity (C. Bouchard, Albert W. Taylor, Jean-Aime Simoneau, and Serge Dulac) Kknanthropometry (WD. Ross and M.J. Marfell-Jones) testing flexibility (C.L. Hubley-Kozey) evaluating the health status of the athlete (R. Backus and D.C. Reid) modelling elite athletic performance (E.W. Banister).
Do Alcohol Expectancy Outcomes and Valuations Mediate Peer Influences and Lifetime Alcohol Use Among Early Adolescents?

ABSTRACT Building on the theory of reasoned action (I. Ajzen & M. Fishbein, 1973, 1980; M. Fishbein & I. Ajzen, 1975) and expectancy theory, the authors examined the mediating role of alcohol expectancies in adolescent drinking behaviors by testing whether alcohol expectancy outcomes and valuations (the extent to which these outcomes are perceived as good or bad) mediate the association between peer influences and lifetime alcohol use. Early adolescents (N = 904) from 2 public middle schools in western Michigan completed a battery of questionnaires. Overall, results showed that alcohol expectancies and valuations partially mediated the relations between peer influences (peer use and peer approval) and lifetime alcohol use. The findings suggest that associating with peers who are perceived as using alcohol and approving of drinking may influence adolescents’ alcohol expectancies. The authors briefly discuss future research directions and implications for prevention.
Perceptions of adolescent wellness at a single-sex school

Although indicators of wellness among minority adolescent females decline over time, this trend has not been examined among adolescents attending single-sex, public schools. Recent evidence has shown that students attending single-sex schools have improved outcomes when compared to co-educational schools. The purpose of this study was to (a) examine whether students attending a predominantly minority single-sex school demonstrated a decline in perceived wellness; (b) identify what it means to be healthy and have a well-balanced lifestyle from the perspective of the school community (viz., students, faculty, and parents); and (c) determine how the school is promoting student wellness. Cross-sectional data were collected from students enrolled at a single-sex, public school in the Southwestern USA. Grades sixth through ninth (n = 338) completed the Survey of Adolescent Wellness (SAW) which assessed their perceived emotional, intellectual, physical, psychological, social, and spiritual wellness. In addition, samples of students (n = 411), faculty (n = 48), and parents (n = 290) answered four open-ended qualitative questions that examined their perceptions of wellness. Multivariate analysis of variance found significant decreases from grades sixth through ninth for each domain of the SAW, with the exception of social wellness. Qualitative data reflected the school's commitment to holistic wellness and strong support of the program by faculty and parents. The decline in perceived wellness among minority adolescent females in this study lends support for existing international trends. Interventions are warranted to address this decline; moreover, the unique social environment that single-sex schools provide needs further exploration.
“Applying anatomy to something I care about”: Authentic inquiry learning and student experiences of an inquiry project

Despite advances to move anatomy education away from its didactic history, there is a continued need for students to contextualize their studies to make learning more meaningful. This article investigates authentic learning in the context of an inquiry‐based approach to learning human gross anatomy. Utilizing a case‐study design with three groups of students (n = 18) and their facilitators (n = 3), methods of classroom observations, interviews, and artifact collection were utilized to investigate students' experiences of learning through an inquiry project. Qualitative data analysis through open and selective coding produced common meaningful themes of group and student experiences. Overall results demonstrate how the project served as a unique learning experience where learners engaged in the opportunity to make sense of anatomy in context of their interests and wider interdisciplinary considerations through collaborative, group‐based investigation. Results were further considered in context of theoretical frameworks of inquiry‐based and authentic learning. Results from this study demonstrate how students can engage anatomical understandings to inquire and apply disciplinary considerations to their personal lives and the world around them.

Structure and Validity of Affect Knowledge Test (AKT) in a Sample of Italian Preschoolers

ABSTRACT The authors’ main goals were to examine whether the Affect Knowledge Test's (AKT) factor structure would be represented by a two-factor model (i.e., emotion recognition and situation knowledge) or by a one-factor model in Italian preschoolers (N = 164; M = 4.24 years, SD = 1.09 years). The concurrent validity of the AKT was further examined using measures of social competence. The findings replicated a model of emotion knowledge, with emotion recognition and situation knowledge as distinct but interrelated factors. Gender and age differences showed that older children and girls displayed higher scores in situation knowledge than younger children and boys. Additionally, our validity model of the AKT demonstrated that emotion recognition preceded situation knowledge, which in turn was positively related to children's sensitive or cooperative behaviors and negatively associated with anxious or withdrawn behaviors. Our results suggest that the use of the AKT may help the teachers to evaluate children's level on emotional knowledge that in turn might impact on children's positive social relationships within classroom in Italy.
Neuroticism and Depression in Children: The Role of Cognitive Emotion Regulation Strategies

ABSTRACT This study's general objective was to analyze whether different types of cognitive emotion regulation strategies (CERS), namely adaptive strategies—specifically positive refocusing and positive reappraisal—and maladaptive strategies—self-blame, catastrophizing, and rumination—mediated the neuroticism-depression relationship in children 9–12 years old, and whether gender and school transition moderated the relationships proposed. A self-reporting measure was administered to 315 children to evaluate said variables. The resulting data were analyzed using structural equations. The study verified that maladaptive CERS partially mediated neuroticism's relationship with depression, while adaptive CERS, though negatively associated with depression, did not show a mediating effect on this relationship. The results provide evidence of the mediating function of maladaptive CERS on the neuroticism-depression relationship. Gender and school transition did not moderate the relationships proposed. Because, by their very nature, these strategies are modifiable, these results constitute an important finding that can be transferred to the design and content of child mental health prevention and promotion programs.
Differential effects of physiological concentrations of retinoic acid in vitro on chondrogenesis and myogenesis in chick craniofacial mesenchyme.

Recent studies have shown that in the developing limb bud retinoic acid is a skeletal morphogen at physiological levels, but a potent teratogen at higher levels. Retinoic acid has also been shown to be teratogenic during facial development, but very low levels may have an as yet unspecified role in normal development. In the present study the effects of retinoic acid on chondrogenesis and myogenesis by craniofacial cells grown in micromass cell culture were investigated. Retinoic acid, at concentrations of 0.01-100 ng/ml, was supplied to cells derived from day-4 (H.H stage 23/24) chick embryo mandibular, maxillary and frontonasal processes, grown in micromass cultures for 4 days in both serum-containing and defined media. Based on Alcian-blue-staining, concentrations of retinoic acid of 0.1-1 ng/ml were found to enhance chondrogenesis by mandibular cells grown in defined medium, while greater concentrations up to 100 ng/ml inhibited chondrogenesis. By contrast, chondrogenesis was generally retarded by all concentrations of retinoic acid applied to frontonasal cells grown in defined medium and when applied to both mandibular and frontonasal cells when grown in serum-containing medium. Cells from stage-23/24 maxillae did not display any significant chondrogenic activity in either medium under these culture conditions. Unlike chondrogenesis, myogenesis in mandibular, frontonasal and maxillary cultures was greater in defined than serum-containing medium, based on the appearance of immunologically detectable muscle myosin, and was reduced considerably less in defined medium by all concentrations of retinoic acid tested. In the presence of serum however, myogenesis was retarded with increasing concentrations of retinoic acid beyond 1 ng/ml in micromass cultures from all three facial regions.

Perceived Parenting Style of Fathers and Iranian Adolescents' Self-efficacy: The Moderating Role of Gender and Education

ABSTRACT The authors examined the moderating role of adolescent's gender and father's education on the associations between perceived paternal parenting styles and self-efficacy in a socioeconomical diverse sample of Iranian ado-lescents (n = 382). Results revealed that paternal authoritative parenting was significantly and positively related to self-efficacy. Interestingly, a significant and positive relation was also found between paternal authoritarian parenting and self-efficacy. This finding might have been the result of the fact that this study was conducted as part of a collectivist culture. In addition, the results indicated that boys who perceived their fathers as highly authoritative indicated higher self-efficacy than girls did. Furthermore, the findings demonstrated that higher educational levels attenuate the negative impact of the permissive parenting style on self-efficacy. The present findings underscore the need to focus on the role of gender and father's education when assessing the link between parenting style and adolescents' self-efficacy.
Cognitive behavioural computer therapy for the anxiety disorders: A pilot study

As part of a wider attempt to improve treatment provision in primary care and to provide greater patient choice, a pilot study of a three session CD-ROM anxiety management programme was tested on 26 carefully assessed and representative long-term sufferers of anxiety disorder living in an area of high social deprivation. The aim was to test whether a successful written package could be turned into an interactive computer package capable of providing a rapid, effective and inexpensive intervention to those patients who wish such an approach. Treatment outcome to 6-month follow-up suggests that this approach was effective and was welcomed by patients.
