What econo-physics can tell us about Korean equity market co-movements?
Authors: Shah Aasif , Deo Malabika , King Wayne 
Published: September 2016

Purpose
The purpose of this paper is to derive crucial insights from multi-scale analysis to detect equity return co-movements between Korean and emerging Asian markets.

Design/methodology/approach
Wavelet correlation, wavelet coherence and wavelet clustering measures are used to uncover Korean equity market interactions which are hard to see using any other modern econometric method and which would otherwise had remained hidden.

Findings
The authors observed that Korean equity market is strongly integrated with Asian equity markets at lower frequency scales and has a relatively weak correlation at higher frequencies. Further this correlation eventually grows strong in the interim of crises period at lower frequency scales. The authors, however, do not found any significant deviation in dendrograms generated in data clustering process from wavelet scale 2 to 6 which are associated with four and 64 weeks period, respectively. Overall the findings are relevant and have strong policy and practical implications.

Originality/value
The unique contribution of this paper is that it introduces wavelet clustering analysis to produce a nested hierarchy of similar markets at each frequency level for the first time in finance literature
Older workers: stereotypes and occupational self-efficacy
Authors: Chiesa Rita , Toderi Stefano , Dordoni Paola , Henkens Kene , Fiabane Elena Maria , Setti Ilaria 
Published: September 2016

Purpose
The purpose of this paper is to explore the relationship between organizational age stereotypes and occupational self-efficacy. First, the authors intend to test the measurement invariance of Henkens’s (2005) age stereotypes scale across two age group, respectively, under 50 and 50 years and older. Then, the moderator role of age groups in the relationship between age stereotypes and occupational self-efficacy is investigated.

Design/methodology/approach
The survey involved a large sample of 4,667 Italian bank sector’s employees.

Findings
The results show the invariance of the three dimensional structure of organizational stereotypes towards older workers scale: productivity, reliability and adaptability. Furthermore, the moderation is confirmed: the relationship between organizational age stereotypes and occupational self-efficacy is significant only for older respondents.

Research limitations/implications
Future studies should aim to replicate the findings with longitudinal designs.

Practical implications
The study suggests the importance to emphasize the positive characteristics of older workers and to reduce the presence of negative age stereotypes in the workplace, especially in order to foster the occupational self-efficacy of older workers.

Originality/value
The findings are especially relevant in view of the lack of evidence about the relationship between age stereotypes and occupational self-efficacy.
Do women only talk about “female issues”? Gender and issue discussion on Twitter
Authors: Evans Heather 
Published: September 2016

Purpose
Recent research has shown that female US House candidates were more likely to talk about so-called “female issues” on Twitter during the 2012 election (Evans and Clark, 2015). In this paper, the author extends this former work by investigating the Twitter activity of all US House representatives during their 2012 election and seven months later (June and July of 2013). The purpose of this paper is to show that women do talk more about “female issues” than men, but do not only focus on these issues.

Design/methodology/approach
This paper content analyzes the tweets sent by female and male representatives in the 113th Congress during their 2012 elections, and seven months later.

Findings
Female representatives spend significantly more time devoted to “female issues” on Twitter than male representatives, but their time is not dominated entirely by “female issues.” Even though the difference is not statistically significant, women sent more tweets about “male issues” than men both during and after the 2012 election. Women tweet more than men about “women,” but they also care about business issues, as is evidenced by that issue being one of the most discussed on Twitter by female representatives during both the election and seven months later.

Originality/value
Unlike other studies on gender and issue discussion, this paper examines a new type of communication: Twitter. Tweets are split by issue type (female/male) and the author sees that while women do discuss “female issues” more than men, they do not exclude “male issues.” This paper also shows that women focus on “female issues” both during elections and after.
Innovating with STEAM in middle school classrooms: remixing education
Authors: Herro Danielle , Quigley Cassie 
Published: September 2016

Purpose
This paper aims to broaden the conversation regarding STEAM by investigating the new form of education. The novelty of science, technology, engineering, art and mathematics (STEAM) instruction in K-12 classrooms means few cases of STEAM teaching are documented in depth.

Design/methodology/approach
As part of a larger multi-year study researching STEAM teaching practices in 14 middle school classrooms in the southeastern USA, the article first summarizes prior research findings and then presents ideas for higher education and K-12 researchers to consider when incorporating STEAM teaching in pre-service education, professional development and in classrooms. Then, the authors use a second-order narrative approach to describe three cases of teachers enacting STEAM practices in classrooms.

Findings
Drawing on the notion of “remixing” education in the context of STEAM, the authors show how each teacher alters existing practices, instead of offering entirely new instruction, as they implement STEAM teaching.

Originality/value
With few cases of STEAM teaching detailed in the depth, this paper advances the understanding of STEAM teaching practices in K-12 classrooms.
Mind the metaphor: charting the rhetoric about introductory programming in K-12 schools
Authors: Burke Quinn 
Published: September 2016

Purpose
The purpose of this article is to review and discuss the varied ways computer programming is introduced to schools and families as a new form of learning. The paper examines the rhetoric around coding within academic journals and popular media articles over the past three decades. This article argues that despite the best intentions of media researchers and enthusiasts, if the rhetoric around computer science (CS) in all K-12 schools is to become a reality, there first needs to be a greater focus on monitoring such rhetoric and better understanding exactly how programming is presented to the wider public.

Design/methodology/approach
This paper represents an analysis of 67 peer-reviewed books and journal articles as well as news articles and editorials related to students’ learning (or needing to learn) computer programming on the K-12 level. In terms of criteria for inclusion, in addition to publication date and article readership, there were three considerations: the article needed to focus on CS on the K-12 grade levels; the article needed to focus on introductory computer programming initiatives, rather than more advanced courses/topics); the article needed to specifically focus on school-based learning environments.

Findings
Findings point to three distinct ways in which introductory coding initiatives have been portrayed (and been perceived): new literacy, “grounded” math and technical skill. Ultimately, the paper does not propose a single defining metaphor. Rather it argues that the metaphors one selects matter considerably in determining programming’s future in entering (or not entering) schools, and that educators need to make a conscientious effort to consider multiple metaphors without choosing just one.

Research limitations/implications
In terms of research limitations, the article does not purport to be an exhaustive analysis of all the metaphors that have been used to introduce CS to K-12 schools over the past 30 years. Rather it only identifies the leading metaphors from the literature, and in doing so, makes an important first step in examining the role of metaphor in the presentation of CS as a “new” course of study.

Practical implications
The article is intended for educators, researchers and administrators to gain a better understanding of what CS is (and could be) for K-12 schooling.

Social implications
The article is intended for educators, researchers and administrators to likewise understand how they, themselves, can present CS to students and families as a potential course of study.

Originality/value
There is currently considerable discussion about teaching CS in all US high schools, middle schools and even elementary schools. There is however little examination of past attempts to bring CS into K-12 schools and what these attempts may inform current advocacy.
Can incidental sighting data be used to elucidate habitat preferences and areas of suitable habitat for a cryptic species?
Authors: HAUSER Wesley R. , HEISE‐PAVLOV Sigrid R. 
Published: September 2016

AbstractThe involvement of communities in ecological studies has been shown to augment conservation efforts, especially for cryptic species. However, there is a lack of studies addressing the utility of incidental sighting records from community members in gaining knowledge on habitat preferences and distribution of suitable habitat for these organisms. This study compares preferences of the Lumholtz's tree kangaroo (Dendrolagus lumholtzi; LTK), a cryptic rainforest folivore in northeastern Australia, for various habitat and climatic variables derived from data collected during scientific projects to those derived from incidental sighting records using ArcGIS and Maxent. Incidental sighting records suggest that the species uses a wider range of altitudes, annual rainfalls, annual mean temperatures and vegetation types than predicted by scientific studies. Incidental records also show that the species can persist in areas of lower rainfall during the wettest month and lower minimum temperature during the coldest month. Both data place the species within a comparable range of rainfalls during the driest month, maximum temperatures of the warmest month and soil types. When using identified preferences to assess the extent and distribution of suitable habitat, incidental records predicted more areas of suitable habitat than scientific records with an overlap of up to 91% between them. The present study proves that incidental sighting records can be a valuable part of the study of cryptic species and should be considered complementarily alongside scientific studies to obtain comprehensive ecological information of a species that can assist in its conservation.
Phenolic Profiles, Antioxidant Activities, and Neuroprotective Properties of Mulberry (Morus atropurpurea Roxb.) Fruit Extracts from Different Ripening Stages
Authors: Yang Jiufang , Liu Xuanjun , Zhang Xiaoxu , Jin Qing , Li Jingming 
Published: September 2016

AbstractThe present work investigated the phenolic profiles (including nonanthocyanin and anthocyanin phenolics), antioxidant activities, and neuroprotective potential of mulberry fruit (MF) (Morus atropurpurea Roxb.) grown in China at different ripening stages. High‐performance liquid chromatography‐tandem mass spectrometry method (HPLC‐MS/MS) was used to identify and quantify the phenolic compounds. The antioxidant capacity, total phenolic content (TPC), total flavonoid content (TFC), and total monomeric anthocyanin content (TAC) were determined using spectrophotometric methods. The neuroprotective effects of MFs at different ripening stages were investigated using Aβ25‐35‐treated PC12 cells as the cellular model of Alzheimer's disease. Of the 19 phenolic compounds characterized from the MF extracts, the contents of rutin and anthocyanins increased and that of chlorogenic acid decreased significantly with maturity. At the fully ripened stage, MF extracts showed the highest amounts of TPC (11.23 mg gallic acid equivalents/g fresh weight), TFC (15.1 mg rutin equivalents/g fresh weight), and TAC (1177 mg cyanidin 3‐O‐glucoside equivalents/100 g fresh weight). Meanwhile, antioxidant activity of MF extracts at this stage was highest according to ABTS (an IC50 value of 4.11 μg/mL) and DPPH (an IC50 value of 10.08 μg/mL) assays. Cellular assays revealed increased cell viability in cells treated with the ripe MF extracts; compared with the control groups, the ripening fruits also increased the antioxidant enzyme levels in PC12 cells. Together, these results suggest that the antioxidant activities and neuroprotective properties of ripening MFs are related to the contents and types of phenolic compounds that are present in the fruits.
Rainforest seed rain into abandoned tropical Australian pasture is dependent on adjacent rainforest structure and extent
Authors: Charles Lachlan S. , Dwyer John M. , Mayfield Margaret M. 
Published: September 2016

AbstractIt is well known that the recovery of abandoned tropical pastures to secondary rainforest benefits from the arrival of seeds from adjacent rainforest patches. Less is known, however, about how the structural attributes of adjacent rainforest (e.g. tree density, canopy cover and tree height) impact seed rain patterns into abandoned pastures. Between 2011 and 2013, we used seed traps and ground seed surveys to track the richness and abundance of rainforest seeds entering abandoned pastures in Australia's wet tropics. We also tested how seed rain diversity is related to the distance from forest, the proportion of forest cover in the landscape and several structural attributes of adjacent forest patches, specifically average tree height, canopy cover, tree species richness and density. Almost no seeds were captured in elevated pasture seed traps, even near forest remnants. Abundant forest seeds were found in ground surveys but only within 10 m of forest edges. In ground surveys, seeds from wind‐dispersed species were more abundant, but less species rich, than animal‐dispersed species. A survey of pasture seedling recruits suggested that some forest seeds must be dispersing more than 10 m into pasture at very low frequencies, but only a few species are establishing there. Recruits were predominantly animal‐dispersed not wind‐dispersed species. In addition to distance from forest and the proportion of forest within a 100‐ to 200‐m radius of sampling sites, the richness and density of adjacent forest trees were the most important factors for explaining the probability of seed occurrence in abandoned pastures. Results suggest that without some restoration assistance, the recovery of abandoned pastures into secondary rainforest in Australia's tropical rainforests will likely be limited, at least in part, by a very low rate of seed dispersal away from forest edges and by the diversity and density of trees in adjacent remnant forests.
Systematic review shows that pathological lead points are important and frequent in intussusception and are not limited to infants
Authors: Fiegel Henning , Gfroerer Stefan , Rolle Udo 
Published: September 2016

AbstractIntussusception is the most clinically relevant cause of bowel obstruction in infancy and can be idiopathic or occur as a result of pathological lead points. The incidence of these pathological lead points varies from 0.3 to 20%, and they can be mucosal, intramural or extrinsic structures. A systematic literature review was performed from 1998 to 2016 to evaluate the incidence and types of pathological lead points in paediatric intussusception, and this identified 31 epidemiological and retrospective case cohort studies, reviews and case reports.Conclusion: Pathological lead points were frequent in intussusceptions and not limited to infants.

Published: September 2016

Heparan sulfate‐specific endosulfatase‐2 (SULF‐2) can modulate the signaling of heparan sulfate proteoglycan‐binding proteins. The involvement of SULF‐2 in cancer growth varies by cancer type. The roles of SULF‐2 expression in the progression and prognosis of renal cell carcinomas (RCC) have not yet been fully clarified. In the present study, the expression levels of SULF‐2 mRNA and protein in 49 clinical RCC samples were determined by RT‐PCR and immunostaining. The existence of RCC with higher SULF‐2 expression and lower SULF‐2 expression compared to the adjacent normal kidney tissues was suggested. High SULF‐2 expression was correlated with an early clinical stage and less invasive pathological factors. Low SULF‐2 expression was correlated with an advanced stage and higher invasive factors. Three‐year cancer‐specific survival (CSS) for high SULF‐2 RCC and low SULF‐2 RCC were 100% and 71.4%, respectively (log‐rank P = 0.0019), with a significantly shorter CSS observed in low SULF‐2 RCC patients. The influence of SULF‐2 expression level on Wnt/VEGF/FGF signaling, cell viability and invasive properties was examined in three RCC cell lines, Caki‐2, ACHN and 786‐O, using a SULF‐2 suppression model involving siRNA or a SULF‐2 overexpression model involving a plasmid vector. High SULF‐2 expression enhanced Wnt signaling and Wnt‐induced cell viability, but not cell invasion. In contrast, low levels of SULF‐2 expression significantly enhanced both cell invasion and viability through the activation of VEGF/FGF pathways. RCC with lower SULF‐2 expression might have a higher potential for cell invasion and proliferation, leading to a poorer prognosis via the activation of VEGF and/or FGF signaling.

Published: September 2016

AbstractAimsThis study aimed to investigate whether an established behavioural intervention, Walking Away from Type 2 Diabetes, is effective at promoting and sustaining increased walking activity when delivered within primary care.MethodsCluster randomized controlled trial involving 10 general practices recruited from Leicestershire, UK, in 2009–2010. Eight hundred and eight (36% female) individuals with a high risk of Type 2 diabetes mellitus, identified through a validated risk score, were included. Participants in five practices were randomized to Walking Away from Type 2 Diabetes, a pragmatic 3‐h group‐based structured education programme incorporating pedometer use with annual follow‐on refresher sessions. The primary outcome was accelerometer assessed ambulatory activity (steps/day) at 12 months. Longer term maintenance was assessed at 24 and 36 months. Results were analysed using generalized estimating equation models, accounting for clustering.ResultsComplete accelerometer data for the primary outcome were available for 571 (71%) participants. Increases in ambulatory activity of 411 steps/day [95% confidence interval (CI): 117, 704] and self‐reported vigorous‐intensity physical activity of 218 metabolic equivalent min/week (95% CI: 6, 425) at 12 months were observed in the intervention group compared with control; differences between groups were not sustained at 36 months. No differences between groups were observed for markers of cardiometabolic health. Replacing missing data with multiple imputation did not affect the results.ConclusionsA pragmatic low‐resource group‐based structured education programme with pedometer use resulted in modest increases in ambulatory activity compared with control conditions after 12 months when implemented within a primary care setting to those at high risk of Type 2 diabetes mellitus; however, the results were not maintained over 36 months.

AbstractAimsTo investigate a virtual assistance‐based lifestyle intervention to reduce risk factors for Type 2 diabetes in young employees in the information technology industry in India.MethodsLIMIT (Lifestyle Modification in Information Technology) was a parallel‐group, partially blinded, randomized controlled trial. Employees in the information technology industry with ≥3 risk factors (family history of cardiometabolic disease, overweight/obesity, high blood pressure, impaired fasting glucose, hypertriglyceridaemia, high LDL cholesterol and low HDL cholesterol) from two industries were randomized to a control or an intervention (1:1) group. After initial lifestyle advice, the intervention group additionally received reinforcement through mobile phone messages (three per week) and e‐mails (two per week) for 1 year. The primary outcome was change in prevalence of overweight/obesity, analysed by intention to treat.ResultsOf 437 employees screened (mean age 36.2 ± 9.3 years; 74.8% men), 265 (61.0%) were eligible and randomized into control (n=132) or intervention (n=133) group. After 1 year, the prevalence of overweight/obesity reduced by 6.0% in the intervention group and increased by 6.8% in the control group (risk difference 11.2%; 95% CI 1.2–21.1; P=0.042). There were also significant improvements in lifestyle measurements, waist circumference, and total and LDL cholesterol in the intervention group.The number‐needed‐to‐treat to prevent one case of overweight/obesity in 1 year was 9 (95% CI 5–82), with an incremental cost of INR10665 (£112.30) per case treated/prevented. A total of 98% of participants found the intervention acceptable.ConclusionsA virtual assistance‐based lifestyle intervention was effective, cost‐effective and acceptable in reducing risk factors for diabetes in young employees in the information technology industry, and is potentially scalable.
