Authors: Singh Shivendra , Pandita Ramesh 
Published: July 2017

PurposeThe purpose of this paper is to examine the impact and role of libraries of the Institutes of Management in India in their research output. The study is based on the seven point performance evaluation parameter, whereby each individual library has been ranked on the basis of aggregate performance against each individual parameter. Some of the key parameters evaluated, include, preference of resource procurement namely, electronic or print, utilisation of library budget towards the procurement of print and electronic resources, average fund utilisation on resource procurement against each published research article and average fund utilisation on resource procurement against each faculty member. Research output against each faculty member and various other similar aspects have been evaluated.Design/methodology/approachThe study is limited to the management institutes of India, but the findings can be generalised to assess omit it the overall trend across the management institutes in general and India in particular. The study is based on 2016 ranking list of Institutes of Management in India, compiled and released by the Ministry of Human Resource and Development, Govt. of India for the period 2012-2013, 2013-2014 and 2014-2015.FindingsFrom the data analysis, it emerged that almost three-fourth of the library budget in the leading Management Institutes across India is being spent on the procurement of e-documents, mostly in the form of subscription of online journals. On average 1.18 research articles have been published by each faculty member during the period of study from each institute under study, with an average annual institutional research output of 19.63 research articles. In terms of resource allocation, on average Indian Rupees (INR) 0.986/million has been spent by each institutional library on the resource procurement against each published research article, and INR1.166/million has been spent on the resource procurement against each faculty member.Practical implicationsThe study is an attempt to seek correlation between the money spend on the procurement of resources and its direct impact on the research output of that particular institution.Originality/valueThe study is original and first of its kind, undertaken in India.
An investigation of the online presence of UK universities on Instagram
Authors: Stuart Emma , Stuart David , Thelwall Mike 
Published: July 2017

Purpose
Rising tuition fees and a growing importance on league tables has meant that university branding is becoming more of a necessity to attract prospective staff, students, and funding. Whilst university websites are an important branding tool, academic institutions are also beginning to exploit social media. Image-based social media services such as Instagram are particularly popular at the moment. It is therefore logical for universities to have a presence on popular image-based social media services such as Instagram. The purpose of this paper is to investigate the online presence of UK universities on Instagram in an initial investigation of use.

Design/methodology/approach
This study utilizes webometric data collection, and content analysis methodology.

Findings
The results indicate that at the time of data analysis for this investigation (In the Spring of 2015), UK universities had a limited presence on Instagram for general university accounts, with only 51 out of 128 institutions having an account. The most common types of images posted were humanizing (31.0 percent), showcasing (28.8 percent), and orienting (14.3 percent). Orienting images were more likely to receive likes than other image types, and crowdsourcing images were more likely to receive comments.

Originality/value
This paper gives a valuable insight into the image posting practices of UK universities on Instagram. The findings are of value to heads of marketing, online content creators, social media campaign managers, and anyone who is responsible for the marketing, branding, and promoting of a university’s services.
Making sense of comments on YouTube educational videos: a self-directed learning perspective
Authors: Lee Chei Sian , Osop Hamzah , Goh Dion Hoe-Lian , Kelni Gani 
Published: July 2017

Purpose
Through the lens of self-directed theory, the purpose of this paper is to investigate if social technologies such as YouTube will be viable to disseminate educational instructions and in the process empowering learners to take charge of their learning.

Design/methodology/approach
A total of 150 educational videos on YouTube were selected and 29,386 comments extracted using the authors’ customized extraction software application. Sentiment and qualitative content analyses were performed.

Findings
Results indicate that YouTube can play important roles in facilitating online self-directed learning (SDL) as the findings uncovered a variety of learning and social affordances of YouTube. However, caution should be exercised as high views and well-commented videos might not imply quality and credibility. This study concludes that YouTube generally provides a conducive a learning environment that affords learners the resources to meet their SDL objectives.

Research limitations/implications
To the best of knowledge, this is the first study that investigates SDL in social media by combining both qualitative content and sentiment analyses. The study shows that such a hybrid approach of combining two diverse analytical techniques provides an innovative means to make sense of comments expressed in social media.

Practical implications
The results will help educational institutions and policy-makers to craft better programs for public education and create policies to help self-directed learners in evaluating online video resources.

Originality/value
Despite a wealth of literature on the use of technologies to support learning, the majority of work done to date has dealt in the classroom context. Studies on SDL using educational content on YouTube are limited. Hence, this research contributes by providing insights on how educational institutions can move toward the direction of building collaborative digital learning platforms with relevant educational instruction and resources to enable users to participate in lifelong self-learning and education.
External supports in reward-based crowdfunding campaigns
Authors: Bao Zheshi , Huang Taozhen 
Published: July 2017

PurposeThe purpose of this paper is to discuss some drivers which can promote reward-based crowdfunding campaigns and then compare their effects on two categories of cultural and creative projects.Design/methodology/approachThe authors first distinguished the roles of “intrinsic qualities” and “external supports” in crowdfunding campaigns. Then based on the theories of reward-based crowdfunding, impression management and social capital, a research model was built to discuss the effects of external supports and a comparative study was conducted by using data collected from Kickstarter.com.FindingsIt indicates that the three dimensions of external supports (reward support, impression support, and relationship support) have positive effects on film and video and publishing projects. Besides, the authors also found that “category of a project” can moderate the relationship between impression support and crowdfunding performance. The effect of impression support on visual works is different from that on printed works.Research limitations/implicationsThese findings not only prove that external supports actually play an important role in crowdfunding campaigns, but also reveal that for different categories of cultural and creative crowdfunding projects, the effects of external supports are different. Some other theoretical and practical implications are also provided.Originality/valueThis research reveals some details about the important role of external supports in crowdfunding campaigns and compares their effects on different categories of cultural and creative projects. It can provide useful suggestions for improving reward-based crowdfunding performance.

As such, online learning strategies may be a useful tool for improving the financial literacy of high school students. The paper aims to discuss this issue.

Design/methodology/approach
This study uses student-level (N=3,061) and school-level data (n=100) to examine the effectiveness of Soar to Savings, an online learning module that teaches key personal finance and economics concepts.

Findings
The findings show large, positive, and statistically significant gains in learning from pretest to posttest for the student-level and school-level samples.

Originality/value
The results provide evidence that Soar to Savings is an effective tool for increasing financial knowledge.
Australia's national climate: learning to adapt?
Authors: Rickards Lauren , Neale Timothy , Kearnes Matthew 
Published: July 2017

AbstractPride in Australia's extreme climate has long been a part of Australia's national identity. Today, climate continues to be enrolled in a range of nationalistic projects, including the (re)development of climate science and other responses to climate change. In this paper, we outline some of the contours of the ‘Australian national climate’, claims to know it, and four idealised responses to it: bounce back, dismissal, endurance, and migration. We argue that the deeply cultural framing of climate in Australia—in particular, Australians' emphasis on the climate's inherent variability and unknowability, and their own historical adaptability—is being exploited by the federal government and hampering climate change mitigation nationally.

AbstractObjectiveTo identify what New South Wales (NSW) farmers know about Q fever to inform preventive approaches.DesignThematic analysis of qualitative data gathered through semi‐structured individual interviews, focus groups and a community meeting.SettingRural communities in NSW, Australia.ParticipantsA total of 25 farmers participated in individual interviews (n = 4) or three focus groups, each with seven participants (n = 21). A further 27 persons, were involved in a community meeting.Main outcome measuresThemes derived from the interviews, focus groups and community meeting.ResultsKnowledge variations regarding Q fever risk and transmission highlight a need for improved risk communication. Vaccination was viewed as the preferred prevention approach; barriers were raised including time, costs, access to screening/vaccination and General Practitioner (GP) knowledge about Q fever. Local vaccination initiatives were supported.ConclusionsStrengthening existing GP knowledge and services leading to expanded provision of screening/vaccination could improve the coverage of Q fever vaccine in endemic NSW farming and rural communities.
What You Ask Is What You Get: Citizens’ Support for Military Action, But Not Diplomacy, Depends on Question Framing
Authors: Leidner Bernhard , Ginges Jeremy 
Published: July 2017

AbstractDrawing on past research on judgment and decision making, as well as preference reversal, we investigated the impact of question framing on support for military versus diplomatic conflict resolution strategies. In three studies with two heterogeneous samples from the United States and one representative sample from Israel, preferences for military action were substantially stronger when asked in isolation (i.e., “yes/no” [support/reject]) rather than in conjunction with the alternative of diplomacy (i.e., “either‐or” [military or diplomacy]), sometimes even causing a complete reversal from majority support for military action to majority support for diplomacy. These findings point to problems in public opinion polls and scientific research on military support (usually presenting no alternatives), and address issues important for psychology, political science, sociology, and survey methodology. In a real world context, our findings have important implications for governmental decisions on conflict resolution strategies and the implementation of policies based on public opinion.
The impact of a universal intervention targeting perfectionism in children: An exploratory controlled trial
Authors: Vekas Eva J. , Wade Tracey D. 
Published: July 2017

ObjectivesPerfectionism is considered to be an underlying mechanism of relevance to a broad array of indicators of psychological distress. The current research examined the impact of a three‐session intervention targeting perfectionism in children on perfectionism, self‐criticism, and well‐being.DesignThe design of the current study can be considered quasi‐experimental as the intervention and control classes were not randomly allocated but decided by convenience factors at the school level.MethodsStudents (aged 10.08–12.79 years) were allocated to the intervention (N = 107, 41 boys) or control condition (N = 105, 33 boys), completing self‐report assessments on perfectionism, self‐criticism, and well‐being at baseline, post‐intervention, and 3‐month follow‐up.ResultsAt post‐intervention, children in the intervention group had significantly lower perfectionism than the control group (d = 0.35, 95% confidence intervals [CI]: 0.07–0.62) and at 3‐month follow‐up had significantly higher levels of well‐being (d = 0.33, 95% CI: 0.06–0.60). As predicted by theory, decreases in perfectionism mediated the relationship between condition and improved well‐being.ConclusionsThis exploratory study provides evidence for the usefulness of a brief universal prevention programme targeting perfectionism. Future research should use more robust designs, explore longer‐term effects, and the impact on a wider range of variables, including scholastic achievement.Practitioner points

Clinical implications

Perfectionism linked with negative outcomes in children can be decreased in a classroom setting.

Decreasing perfectionism leads to improved well‐being in children.

Limitations

More rigorous designs along with better assessment of perfectionism are required in further evaluations.

The impact of perfectionism on scholastic achievement in children requires further investigation.
Guidelines for Quantitative Evaluation of Medical Visualizations on the Example of 3D Aneurysm Surface Comparisons
Authors: Saalfeld P. , Luz M. , Berg P. , Preim B. , Saalfeld S. 
Published: July 2017

AbstractMedical visualizations are highly adapted to a specific medical application scenario. Therefore, many researchers conduct qualitative evaluations with a low number of physicians or medical experts to assess the benefits of their visualization technique. Although this type of research has advantages, it is difficult to reproduce and can be subjectively biased. This makes it problematic to quantify the benefits of a new visualization technique. Quantitative evaluation can objectify research and help bringing new visualization techniques into clinical practice. To support researchers, we present guidelines to quantitatively evaluate medical visualizations, considering specific characteristics and difficulties. We demonstrate the adaptation of these guidelines on the example of comparative aneurysm surface visualizations. We developed three visualization techniques to compare aneurysm volumes. The visualization techniques depict two similar, but not identical aneurysm surface meshes. In a user study with 34 participants and five aneurysm data sets, we assessed objective measures (accuracy and required time) and subjective ratings (suitability and likeability). The provided guidelines and presentation of different stages of the evaluation allow for an easy adaptation to other application areas of medical visualization.
Aphid suitability for the predatory hoverfly Episyrphus balteatus altered with elevating atmospheric CO2 and sinigrin
Authors: Sadeghi‐Namaghi Hussein , Amiri‐Jami Alireza , Shoor Mahmoud 
Published: July 2017

AbstractThe fitness of natural enemies should be altered in response to changes in herbivore quality induced by the impact of increased atmospheric CO2 levels on plants. We studied the effect of different CO2 levels on the aphid predator Episyrphus balteatus DeGeer fed either specialist or generalist aphids reared on either of two host plants under laboratory conditions. In the host plant that contains sinigrin (black mustard), elevated CO2 increased the sinigrin content of both host plant and the specialist aphid, but reduced the already very low levels in the generalist aphid. Predator development time increased with elevated CO2, while fecundity decreased. Consequently, individual fitness decreased slightly with increasing atmospheric CO2. Sinigrin significantly decreased fecundity and increased development time of the predator. As a result, fitness was significantly lower too. The consumption rate was influenced significantly by plant and prey solely and the interactions of host plant × prey type and CO2 level × prey type. Further research on the effects of climate change parameters (e.g. greenhouse gases such as CO2, ozone (O3) and nitrogen dioxide (NO2), etc.) separately and jointly under controlled environmental conditions will help to understand the nature and direction of their effects on natural enemies as part of the tritrophic system.
A residual stress dependent multiaxial fatigue life model of welded structures
Authors: Liu Z.C. , Jiang C. , Li B.C. , Wang X.G. 
Published: July 2017

AbstractIn this paper, the influence of the residual stress on the fatigue performance of a welded structure under multiaxial loading modes is studied. First, the local stress state at weld toe is modified via introduction of the residual stress, and a new fatigue life estimation model considering the effect of the residual stress is established by modifying our recently proposed critical plane method. Second, the basic theory and procedure of the finite element simulation on the calculation of the welding residual stress are presented. Finally, a numerical simulation of an aluminum alloy flange‐to‐tube welding process is conducted, and the calculated residual stress is verified with X‐ray diffraction measurement. Furthermore, the performance of the proposed fatigue life estimation model is verified by the experimental data obtained in the fatigue test under different loading modes. It confirms that the consideration of the residual stress is important, especially under the out‐of‐phase loading mode.
Zero thermal expansion in cubic MgZrF6

Published: July 2017

AbstractIsotropic zero thermal expansion (ZTE) is rare but intriguing physical property in materials. Here, we report an isotropic ZTE property in a double ReO3‐type compound of MgZrF6, which exhibits a negligible value of coefficient of thermal expansion (αl = −7.94 × 10−7 K−1 (XRD), αl = −4.22 × 10−7 K−1 (dilatometry), 300‐675 K). The ZTE mechanism of MgZrF6 is understood by the joint studies of temperature dependence of crystal structure and lattice dynamics. Interestingly, different magnitudes of atomic displacement parameters (ADPs) for the fluorine atoms in MZrF6 (M = Ca, Ni, Mg) are found. The strong temperature sensitivity of ADPs demonstrates intensive transverse thermal vibration of fluorine atoms, which contributes essentially to the negative thermal expansion of CaZrF6. By contrast, for NiZrF6 with positive thermal expansion, the temperature response of ADPs is weak. Moderate transverse thermal vibration takes place in MgZrF6, and ZTE appears. Furthermore, lattice dynamics of MgZrF6 is studied by temperature‐dependent Raman spectroscopy, which reveals the ZTE mechanism. In particular, the F2g and Ag modes, corresponding to the bending and stretching vibrations of fluorine atoms, respectively, neither soften nor harden over the whole temperature range, which is correlated with the isotropic ZTE property of MgZrF6.
Phylogenetic estimates of diversification rate are affected by molecular rate variation
Authors: Duchêne D. A. , Hua X. , Bromham L. 
Published: July 2017

AbstractMolecular phylogenies are increasingly being used to investigate the patterns and mechanisms of macroevolution. In particular, node heights in a phylogeny can be used to detect changes in rates of diversification over time. Such analyses rest on the assumption that node heights in a phylogeny represent the timing of diversification events, which in turn rests on the assumption that evolutionary time can be accurately predicted from DNA sequence divergence. But there are many influences on the rate of molecular evolution, which might also influence node heights in molecular phylogenies, and thus affect estimates of diversification rate. In particular, a growing number of studies have revealed an association between the net diversification rate estimated from phylogenies and the rate of molecular evolution. Such an association might, by influencing the relative position of node heights, systematically bias estimates of diversification time. We simulated the evolution of DNA sequences under several scenarios where rates of diversification and molecular evolution vary through time, including models where diversification and molecular evolutionary rates are linked. We show that commonly used methods, including metric‐based, likelihood and Bayesian approaches, can have a low power to identify changes in diversification rate when molecular substitution rates vary. Furthermore, the association between the rates of speciation and molecular evolution rate can cause the signature of a slowdown or speedup in speciation rates to be lost or misidentified. These results suggest that the multiple sources of variation in molecular evolutionary rates need to be considered when inferring macroevolutionary processes from phylogenies.
