Professional and academic knowledge in teachers’ research: An empowering oscillation

In this article, we study the academisation of the teaching profession in Sweden, which follows contemporary trends in other Nordic and European countries. The specific aim was to analyse 14 reports written by researching teachers enrolled in a master’s programme to investigate how they perceive, interpret and value academic and professional knowledge. The conceptual framework comprises theories concerning academic literacies and knowledge structures. The report analysis focussed on scope, aims and research questions, and how the researching teachers related to teacher knowledge and academic knowledge, normativity and a critical approach. After a preliminary analysis, the researching teachers were invited to participate in the analysis, giving their contextual understanding. The study indicates that the reports were based on empirical data and situated in a professional context, with the aim of exploring and understanding professional issues in relation to research, national policies and professional teacher experience. Report orientation was deeply nourished by teacher knowledge. The researching teachers’ contextual knowledge both benefitted and challenged academic knowledge and vice versa, with the ambition to improve practice. Accordingly, the teachers’ contextual knowledge can deepen the understanding of a research phenomenon. There was an empowering oscillation between teacher knowledge and academic knowledge in the teachers’ research.
Two stage reconstruction of flexor tendon injuries in zone II after missed injury or failed repair

Background: Reconstruction of flexor tendon injury of the hand after failed tendon repair or missed injury is a technically challenging problem. Repair of the tendon within the thin tight pulley system usually invites the formation of adhesion and failure of repair. A combination of a technique described by Paneva-Holevich and Hunter has been used for this problem with variable results. Methods: Twenty-five flexor tendons in 20 patients were reconstructed using a two-stage reconstruction of the flexor tendon injury. The preoperative condition of the finger was evaluated using Boyes and Stark grading modified by Wehbe et al. and all had a poor prognosis. The primary tendon injury was missed in nine patients. Primary tendon repair failed in seven patients and free tendon graft failed in three. One patient had two operative interventions: one failed primary tendon repair and one failed free tendon graft. The dominant hand was affected in (70%) of patients. Results: The average time between the original injury and the first stage operation was 10.6 mo. The mean follow-up after the second stage was 72 mo. The mean strength of pinch grip and power grip were 92.4% and 94.8%, respectively. The mean pulp to distal flexion crease distance was 12.32 mm. According to Buck-Gramcko scoring, excellent results were achieved in 18 fingers (72%), good in five fingers (20%), fair in one (4%), and poor in one (4%). No additional surgery was required after the second stage. Conclusions: The two-stage pedicled flexor digitorum superficialis technique provided a reliable and effective method for reconstruction of failed repair or missed injury of the flexor tendon in the hand in zone II. The modification of the technique presented in this study achieved a high rate of excellent and good results without increasing the rate of complications. Patient compliance is critical for the success of this procedure.
Asian and African Business Students: A Comparative Analysis of their Motivation, Family Support and Culture on Business Orientation

Originality/Value: This research specifies and focuses on comparative analysis of Asian and African business students, the result can be use for design the business students curriculum, therefore the business motivation indexes of Asian and African can be increase through entrepreneurship education in business schools.
How Downplaying Product Greenness Affects Performance Evaluations: Examining the Effects of Implicit and Explicit Green Signals in Advertising

Despite frequent reports that they favor products with environmental benefits, consumers often purchase conventional alternatives. One reason for this is the performance liability associated with green products, in which consumers perceive them as being less effective. This research examines the concept of “green understatement” (i.e., communication of implicit green signals) compared with “green emphasis” (i.e., communication of explicit green signals) in green product advertising as a strategy to enhance performance evaluations. We test whether, why, and when an implicit (versus explicit) advertising strategy leads to higher performance evaluation for green products. We suggest and show that implicit green signals are more effective in conditions under which consumers have more concerns about the product’s performance or have lower expectations about its greenness. More specifically, the results of two experimental studies show that implicit (versus explicit) communication about greenness leads to higher performance evaluations for products that are less commonly green (Study 1) and for products that have an optional green mode (Study 2). The findings aid in the understanding of how a green product advertising strategy may influence performance evaluations and provide managerial implications for green product promotion.
Performance Analysis of a New Switched Reluctance Motor With Two Sets of Embedded Permanent Magnets

This article proposes an enhanced-torque switched reluctance motor with two sets of permanent magnets (PM-SRM) embedded inside the stator yoke and the end teeth of the neighboring modules. The PMs contribute to intensify the air-gap flux density and reduce the magnetic saturation in the stator poles. As a result, the output torque can be enhanced to a significant extent. The working principle of the proposed PM-SRM is clarified using its magnetic circuit model (MCM). The characteristics of the PM-SRM are obtained and compared with classical 12/8 and 6/5 SRMs and hybrid reluctance motors (HRMs) in terms of static and average torque and average torque per PMs volume. The steady-state performance of the PM-SRM in terms of current and torque waveforms is carried out, and the PM-SRM is compared with considered SRMs and HRMs in terms of output torque, power, and efficiency. All the comparisons demonstrate the out-performance of the proposed PM-SRM over other SRMs and HRMs. To validate the simulation results, a prototype of the PM-SRM is manufactured and the experimental results are obtained. Both the simulation and experimental results are indicative of the fact that the proposed PM-SRM can gain high torque and high PM utilization factor, simultaneously.
Still Minding the Gap? Reflecting on Transitions between Concepts of Information in Varied Domains

This conceptual paper, a contribution to the tenth anniversary Special Issue of Information, gives a cross-disciplinary review of general and unified theories of information. A selective literature review is used to update a 2013 article on bridging the gaps between conceptions of information in different domains, including material from the physical and biological sciences, from the humanities and social sciences including library and information science, and from philosophy. A variety of approaches and theories are reviewed, including those of Brenner, Brier, Burgin and Wu, Capurro, Cárdenas-García and Ireland, Hidalgo, Hofkirchner, Kolchinsky and Wolpert, Floridi, Mingers and Standing, Popper, and Stonier. The gaps between disciplinary views of information remain, although there has been progress, and increasing interest, in bridging them. The solution is likely to be either a general theory of sufficient flexibility to cope with multiple meanings of information, or multiple and distinct theories for different domains, but with a complementary nature, and ideally boundary spanning concepts.

Validity and reliability of Verbal Online Subjective Opinion (VOSO) and Modified Cooper-Harper scales in measuring of mental workload

Introduction: High mental workload is one of the important factors that results in errors in safety and occupational health scope, and its measurement has high importance. Therefore, this study aimed at determining the validity and reliability of Verbal Online Subjective Opinion (VOSO) and Modified Cooper-Harper (MCH) scales in measuring mental workload. Methods: This study was conducted on 90 male students of Iran University of Medical Sciences. In this study, forward-backward translation was used for translation of scales. Moreover, Content Validity Ratio (CVR) and Content Validity Index (CVI) were calculated considering the suggestions of 6 ergonomics and occupational health experts. The Hybrid Memory Search Task software was used to create mental workload. Convergent validity of scales was calculated using correlation of scales with reaction time and then test-retest method was used to determine the reliability of scales. Results: Content and convergent validity of scales were confirmed and correlation of both scales with reaction time were higher than 0.8. Moreover, for determination of scales reliabilities, Pearson correlation coefficient between scales values in test and retest trials were 0.86 and 0.91 for VOSO and MCH, respectively. Conclusions: It seems that in regards to confirmation of validity and reliability of VOSO and MCH in this study and their high correlation with reaction time, these scales could be used in measurement of mental workload. Validity and Reliability of Verbal Online Subjective Opinion (VOSO) and Modified Cooper-Harper Scales in Measuring of Mental Workload.
Problematising early childhood teacher registration as a mechanism to improve quality early childhood education and care

Regulatory drivers of teacher quality and teacher professionalism are increasingly being utilised in Australia and internationally to improve children’s outcomes. In the context of a recent national review on teacher registration, this article reports on findings from a small-scale study that investigated three early childhood teachers’ perceptions of teacher registration in New South Wales, Australia. The participants rejected discursive truths about the need for and benefits of teacher registration, associating this relatively new mechanism of teacher accountability as a threat to teachers’ professional practice and job satisfaction, and to centres’ provision of quality early childhood education. The findings problematise a discourse of teacher professionalism made enticing by a vow to bring early childhood teachers in from the margins of the educator sector.
Epidemiology of Irritable Bowel Syndrome in Saudi Arabia

The irritable bowel syndrome (IBS), is a clinical syndrome characterized by chronic abdominal dis-comfort, is the most mutual complaint met by gastroenterologists. IBS associated with symptoms in bowel habits, which can't be clarified by any biochemical or organic disorders. The most common symptoms include, the existence of current or recurrent abdominal pain or discomfort accompanying with bloating and altered bowel habits. These symptoms could intensely change the quality of life. Several reports confirms the existence of dysfunction of the intrinsic enteric nervous system (ENS). Several reports have revealed that inflammation and immune dysregulation disturb the sensitivity of nerve fibers. A relatively high prevalence of IBS was reported in several Saudi studies with variable study population settings. This review is mainly focused on the current status of IBS in the Kingdom Saudi Arabia (KSA) in light of the existent literature. The prevalence of IBS in Saudi Arabia among the available literature was slightly higher but relatively comparable to some worldwide reports.
Leaf Senescence in Arabidopsis thaliana and Brassica napus: From Molecular Regulation to Nutrient Remobilization Processes

Leaf senescence is highly regulated by transcriptional reprogramming, implying an important role for transcriptional regulators. ETHYLENE RESPONSE FACTOR4 (ERF4) was shown to be involved in senescence regulation and to exist in two different isoforms due to alternative polyadenylation of its pre-mRNA. One of these isoforms, ERF4-R, contains an ERF-associated amphiphilic repression (EAR) motif and acts as repressor, whereas the other form, ERF4-A, is lacking this motif and acts as activator. Here, we analyzed the impact of these isoforms on senescence. Both isoforms were able to complement the delayed senescence phenotype of the erf4 mutant with a tendency of ERF4-A for a slightly better complementation. However, overexpression led to accelerated senescence of 35S:ERF4-R plants but not of 35S:ERF4-A plants. We identified CATALASE3 (CAT3) as direct target gene of ERF4 in a yeast-one-hybrid screen. Both isoforms directly bind to the CAT3 promoter but have antagonistic effects on gene expression. The ratio of ERF4-A to ERF4-R mRNA changed during development, leading to a complex age-dependent regulation of CAT3 activity. The RNA-binding protein FPA shifted the R/A-ratio and fpa mutants are pointing towards a role of alternative polyadenylation regulators in senescence.
The Correlation Between Hiv/aids Knowledge And The Hiv/aids Preventive Attitude In Homeless Children At Girlan Nusantara Halfway House Of Sleman Yogyakarta In 2015

Background: Teenagers need knowledge on reproductive health as their insight to grow as adult and face the social interaction which gets more open and free. The lack of socialization on HIV/AIDS knowledge causes most of Indonesians lack of understanding the transmission of HIV/AIDS which leads to the low positive attitude towards HIV/AIDS prevention. Homeless children and housewives are the risky group which need special and serious attention. Objectives: The aims to reveal the correlation between HIV/AIDS knowledge and preventive attitude.

Conclusion: There is a significant correlation between HIV/AIDS knowledge and preventive attitude in homeless children at the Girlan Nusantara halfway house of Sleman Yogyakarta in 2015
Valuation and Long-Term Growth Expectations

A standard DCF corporate valuation usually includes a terminal value based on a long-term growth rate to reflect value from beyond the typical forecasting horizon of three to seven years. Despite often having a dominant effect on overall firm value, both the academic literature and practitioner conventions provide very little guidance on how this long-term growth rate should be determined. This paper addresses this gap: we undertake an exploratory analysis of how firms’ long-term growth is related to various firm and industry characteristics. We apply an extensive selection of potential predictors based on firm, industry, and market characteristics, in order to explain the variation in firms’ long-term growth rates. As such, we provide a predicted long-term growth rate for all firms, which can then be used as an input into a DCF valuation. We find that market prices do not seem to capture the full information that we find in long-term growth predictions. Thus, a trading strategy that goes long the decile with the highest long-term growth expectations and short the bottom decile yields positive and statistically significant abnormal returns in the range from ten to thirteen percent per year.

Forecasting Option Prices Using Discrete-Time Volatility Models Estimated at Mixed Timescales

Option pricing models traditionally have utilized continuous-time frameworks to derive solutions or Monte Carlo schemes to price the contingent claim. Typically these models were calibrated to discrete-time data using a variety of approaches. Recent work on GARCH-based option pricing models have introduced a set of models that easily can be estimated via MLE or GMM directly from discrete time spot data. This article provides a series of extensions to the standard discrete-time options pricing setup and then implements a set of various pricing approaches for a very large cross section of equity and index options against the forward-looking traded market price of these options, out of sample. The authors’ analysis provides two significant findings. First, they provide clear evidence that including autoregressive jumps in the options model is critical in determining the correct price of heavily out-of-the money and in-the-money options relatively close to maturity. Second, for longer maturity options, they show that the anticipated performance of the popular component GARCH models, which exhibit long persistence in volatility, does not materialize. They ascribe this result in part to the inherent instability of the numerical solution to the option price in the presence of component volatility. Taken together, their results suggest that when pricing options, the first best approach is to include jumps directly in the model, preferably using jumps calibrated from intraday data. TOPICS: Options, volatility measures Key Findings • This article presents a new method for estimating the parameters for a jump GARCH model. The authors provide a series of empirical tests of the efficacy of the GARCH-type option models. They analyze the S&P 500 Index and 20 individual equities sampled from the Dow Jones 30. Their out-of-sample test covers over a third of a million individually equity traded prices. • They find three primary empirical results. First, pre-filtering for jumps improves the accuracy of option models based on GARCH processes. Second, for certain stocks, models that explicitly incorporate jumps substantially outperform all other models. Third, for the S&P 500, the GARCH model estimated on jump-filtered returns appears to dominate.
