Topography's crucial role in Heinrich Events
Authors: Roberts William H. G. , Valdes Paul J. , Payne Antony J. 
Published: November 2014

Significance
Heinrich Events are frequently promoted as examples of an abruptly forced climate change. Although the evidence for changes in the ice sheets, which cause these events, is clear, the pathway by which these changes can affect the climate is not. The most common explanation is that the melting icebergs released by the ice sheet cause a change in the ocean’s circulation. Here we propose that the change in the height of the ice sheet, which changes the atmospheric circulation, is just as important. We must therefore reassess the simple paradigm that the climate changes that occurred during Heinrich Events are solely the result of a change in the ocean’s circulation.

Published: November 2014

Significance
The brain is a large-scale network, not unlike many social or technological networks. Just like social networks, brain networks contain subnetworks or systems of highly related or interacting nodes (in the case of brains, nodes may represent neurons or brain areas). Using functional MRI to measure functional correlations between brain areas during periods of rest, we describe differences in brain network organization in a large group of individuals sampled across the healthy adult lifespan (20–89 y). We characterize a measure of system segregation, reflecting the degree to which the systems share connections among one another. Increasing age is accompanied by decreasing segregation of brain systems. Importantly, system segregation is predictive of measures of long-term memory function, independent of age.

Significance
Production of functional sperm and eggs requires a complex process called meiosis. Meiosis in mouse and human eggs pauses at a stage called metaphase II (MII) arrest until fertilization by sperm. After fertilization, eggs released from MII arrest complete meiosis and develop into new individuals. In analyzing the female infertility of genetically altered mice, we discovered that excess cholesterol can trick mouse eggs into behaving as though they were fertilized (released from arrest), thus disrupting the normal synchrony between fertilization and completion of meiosis and rendering them dysfunctional. These findings suggest that abnormal cholesterol metabolism may contribute to some forms of human female infertility.
Ventromedial prefrontal cortex supports affective future simulation by integrating distributed knowledge
Authors: Benoit Roland G. , Szpunar Karl K. , Schacter Daniel L. 
Published: November 2014

Significance
Decisions concerning the future are often informed by past experiences. However, in a complex world, we frequently have to make choices for prospective scenarios that we haven’t yet encountered. The present study demonstrates a critical role for the ventromedial prefrontal cortex in simulating what it may feel like to experience such future events. We show that this region contributes to integrating knowledge related to the elements that constitute the episode (e.g., the episode’s location and protagonists). Its activation then indicates the episode’s emergent or overall anticipated affective quality. By this process, the ventromedial prefrontal cortex fundamentally supports our ability to predict possible future affective states, a mechanism that can be flexibly used to augment future oriented decisions.
Inelastic and Fragmented Farm Supply Response for Second‐generation Bioenergy Feedstocks: Ex Ante Survey Evidence from Wisconsin
Authors: Mooney Daniel F. , Barham Bradford L. , Lian Chang 
Published: November 2014

AbstractSecond‐generation bioenergy feedstocks stand poised to become a key component of the nation's agricultural and energy sectors, yet few studies have examined farm supply response using survey information. We use contingent valuation data from farmers in southwestern Wisconsin to develop ex ante supply estimates for two prospective feedstocks—corn stover and switchgrass—in terms of farmers' extensive and intensive acreage decisions. Supply response is found to be price inelastic and spatially fragmented, making widespread production unlikely in the near‐term. However, heterogeneity in farmer reservation prices suggests that agglomerations or “hot spots” of feedstock supply could arise at local or regional levels.

The findings highlight the benefits to mentors and mentees and the challenges for ensuring participant engagement and ongoing development. The article concludes with an agenda for further mentoring developments in the midst of the dynamic challenges facing UK higher education institutions and the hospitality and tourism industry.Practical implicationsThe article highlights the importance of a systematic approach to developing a mentoring programme and engaging industry in a distinctive way with the transitioning of undergraduates into the workplace.Originality/valueThis article offers unique evidence of an employer engagement initiative aimed at supporting sector specific management graduates as they transition from university into industry.
Generic skills development and satisfaction with groupwork among business students
Authors: Teo Stephen T.T. , Segal Naomi , Morgan Adam C. , Kandlbinder Peter , Wang Karen Y. , Hingorani Anurag 
Published: November 2014

PurposeThe purpose of this study is to examine variables explaining students’ positive and negative experiences of groupwork and connect country of residence with the perception of generic skills development and self‐reported satisfaction with groupwork. It also aims to examine the effect of prior training in groups from the perspective of Australian and Non‐Australian permanent residency Business students.Design/methodology/approachRespondents were 389 undergraduate and postgraduate Business students at an Australian metropolitan university. A path model was developed and analysed using partial least squares modeling.FindingsStudents’ country of residence had a significant influence on reporting of generic skill development and experience of groupwork. Self‐reported improvement in generic skills after groupwork assessment was associated with reporting of fewer negative and more positive aspects of working in groups.Research limitations/implicationsThe findings were limited by using data collected from students enrolled in one undergraduate and one postgraduate subject at the conclusion of a group assignment from one university. Future research should test the model by extending it to other universities and non‐Business units. Future research should rely on a longitudinal design, where the survey is carried out at the beginning and the end of the group assessment.Practical implicationsIt is important to ensure both domestic and international students acquire generic skills through groupwork and that prior training in groupwork takes place before group assessments.Originality/valueThe study provides empirical evidence supporting the incorporation of generic skill teaching into academic practice prior to assigning groupwork to students.
Outreach initiatives in academic libraries, 2009‐2011
Authors: Dennis Melissa 
Published: November 2014

PurposeWith outreach responsibilities on the rise in academic libraries and budgets declining or remaining stagnant, finding outreach initiatives that support the university in creative ways are on the rise. This study seeks to compare outreach initiatives by academic librarians to a project conducted by the author.Design/methodology/approachAcademic librarians with responsibilities in outreach, marketing, and promotion were targeted in a survey sent to listervs in the Summer of 2011. A total of 21 academic librarians described successful outreach initiatives. A small response rate reflects the target audience.FindingsThe survey revealed a wide range of outreach initiatives that compare funding: library, university, grant, and other. The author's project greatly exceeded the cost of all other initiatives.Research limitations/implicationsThe research identifies survey flaws and a small reach to the targeted audience. Suggestions for future research include a modified survey to the Association of Library Communications and Outreach Professionals.Practical implicationsTechnology advancements and budget restraints have put pressure on outreach librarians to provide successful programs with less funding. Many colleges and universities across the nation have inserted outreach into public services positions.Originality/valueThe literature produces limited research about successful outreach initiatives over the past five years where economic duress has been nationwide. Outreach librarians will find inspiration in the collected outreach projects undertaken at 21 colleges and universities across America to create projects with limited funding.
Nerd thrill your users
Authors: Niccole Westbrook R. , Prilop Valerie , German Elizabeth M. 
Published: November 2014

PurposeThe purpose of this paper is to present a case study in which reference librarians were a catalyst for an innovative web project designed to market digital collections to students and faculty. The web project was titled “Image Café” and offered users a taste of the materials available in the University of Houston Digital Library in an interface and format that was simple to navigate and that encouraged reuse of the materials, specifically in presentations.Design/methodology/approachThe approach to this project was a collaborative strategy in which a team of digital librarians reached out to reference librarians to engage them in more effective promotion of digital collections to students and faculty. Prior to this project, reference librarians were an under‐utilized stakeholder group whose feedback about the organization and presentation of digital collections had been difficult to implement. The Image Café project was an opportunity to pilot ideas directly from the librarians focused on outreach to students and faculty in an effort to make digital collections more approachable and discoverable for that audience.FindingsBased on initial findings, use of Image Café has been strong and consistently growing.Originality/valueThis paper provides a valuable model for building bridges between groups within libraries that do not traditionally collaborate in order to make digital collections intuitive and relevant for users.
Toward a general model for executive compensation
Authors: Farid Mamdough , Conte Vincent , Lazarus Harold 
Published: November 2014

PurposeThis paper aims to review the growing literature on the issues and variables which are impacting the determination of CEO pay for Fortune 500 and other large organizations. While many previous researchers have focused on agency theory, CEO power, market forces and board of directors governance as the most relevant issues, the authors seek to propose a general model for determining CEO pay which has a more comprehensive set of variables.Design/methodology/approachThe paper draws on existing literature to derive the variables for the proposed model.FindingsThe bulk of the literature reviewed takes an Anglo‐American point‐of‐view on the best way to manage CEO pay. There is a need for a more “balanced” and broader perspective on how to motivate CEO behavior with the needs of other stakeholders.Originality/valueThe paper provides new insights into the dynamic nature of CEO motivation and governance and by designing a general model, integrates divergent points of view into a more holistic body of knowledge.

Authors: Yuan Chaoqing , Song Dejin , Guo Benhai , Xie Naiming 
Published: November 2014

PurposeThe purpose of this paper is to attempt to analyze the situation and trend of China's energy consumption structure and predict it.Design/methodology/approachStarting from the situation of China's energy consumption structure, a quadratic programming model is created to analyze the trend of it. A homogeneous Markov chain is chosen to predict China's energy consumption structure with the data collected from China's Statistical Yearbook. Finally, the implication of the prediction is explained.FindingsThe results are convincing: the substitution of different energies are found, China will not enter the oil era, natural gas and non‐fossil energy will rapidly develop.Practical implicationsThe results of this article can provide an important basis for the government to make a non‐fossil energy development plan and energy policies.Originality/valueThe paper succeeds in revealing and predicting China's energy consumption structure by quadratic programming and homogeneous Markov chain.
Computational intelligence techniques for communities network formation
Authors: Maries Iulia , Scarlat Emil 
Published: November 2014

PurposeThe purpose of this paper is to analyse the role of computational intelligence techniques in the process of communities' formation.Design/methodology/approachThe paper develops a high performance genetic algorithm for community formation based on collective intelligence capacity. An experimental study is presented to illustrate the algorithm.FindingsCollective intelligence does not represent the sum of individual intelligences, it is the ability of the community to complete more tasks than single individuals. The paper reveals the need for mechanisms that allow a large group of professionals to make decisions better than single individuals.Practical implicationsThe genetic algorithm proposed in the paper may be used to obtain the optimal structure of a community, in terms of number of members and their role in the community.Originality/valueThe key concept is a new fitness index, an intelligence index, which is the optimal combination between intelligence and cooperation, and allows not only community formation, but also intelligence to be the driving principle in the community formation process.
Image edge detection based on the grey prediction model and discrete wavelet transform
Authors: Wang Qiuping , Wang Tiepeng , Zhang Ke 
Published: November 2014

PurposeImage edge detection is an essential issue in image processing and computer vision. The purpose of this paper is to provide a novel and effective algorithm for image edge detection.Design/methodology/approachBecause GM (1,1) model is a typical model for tendency analysis, GM (1,1) model can be used for detecting edge. Prediction image data are close to the original image data by reason of the data being smooth in the non‐edge zone of image. The principle of edge detection by GM (1,1) model is that the predicted value at an edge point will be an overestimate or underestimate owing to the data changing drastically in the edge zone of the image. First, the edge image information is obtained by a preprocessed image subtracting from prediction image via GM (1,1). Second, median filter is used to eliminate isolated point noise in edge information images, and discrete wavelet transform is used to extract the image edge. Finally, this paper verifies the proposed algorithm by experiment.FindingsExperimental results show that the proposed algorithm has advantages such as precisely locating, abundant weak edge, and better anti‐noise performance.Practical implicationsThe algorithm proposed in the paper can precisely detect the information of edge image, and get a clear image detail.Originality/valueGrey system theory developed vigorously lays the foundation for image processing. Wavelet analysis in image processing has its characteristics. This paper combines grey prediction model with discrete wavelet transform (DWT) successfully and obtains a novel and effective algorithm for image edge detection.
A dynamic evaluation model of university leading cadre based on multivariate delay connection number
Authors: Tao Yong , Shen Feifei , Hu Mingli 
Published: November 2014

PurposeSince the present university leading cadre capability evaluations are mainly static, there is a lack of evaluation methods to address dynamic and multi‐scale‐based situations. Some important factors to address people's performances, such as the developing trends and potentialities are considered. The purpose of this paper is to attempt to propose a dynamic evaluation model based on multivariate delay connection number.Design/methodology/approachFirst, evaluation results of previous periods are taken into the current period and values of uncertain numbers are revised. Next, a dynamic evaluation model is built for university leading cadre. Last, a numerical example is used to prove its feasibility and effectiveness.FindingsThis paper promotes a corrected equal portion value method of uncertain numbers i1(τ), … ,in(τ) from the adjacent two periods to multi periods, and builds a dynamic evaluation model, which proved simple‐structured and easy to apply.Practical implicationsThe new model is applied in the evaluation of university leading cadre, and could give a more comprehensive, dynamic, scientific analysis for evaluation by model application.Originality/valueThe paper develops a novel evaluation model based on a multivariate delay connection number, which expands traditional methods from a static situation to a dynamic and multi‐scale‐based situation.

Authors: Asif Muhammad , Krogstie John 
Published: November 2014

PurposeA mobile student information system (MSIS) based on mobile computing and context‐aware application concepts can provide more user‐centric information services to students. The purpose of this paper is to describe a system for providing relevent information to students on a mobile platform.Design/methodology/approachThe research followed a design science approach, including surveys to argue for the relevance of the system and evaluation of different versions of the system using a mobile system acceptance model (MSAM).FindingsIt was found that the intention to use such services is high, in particular relative to services providing information based on localization and the personal schedule and interests of the student.Originality/valueSeveral mobile systems exist that provide generic campus information for students and this paper describes one of the few systems of this sort of personalization which have been evaluated.

Authors: Chen Kuo‐Hsiang , Shen Kai‐Shuan , Ma Min‐Yuan 
Published: November 2014

PurposeThe purpose of this study is to explore the appeal of social networking services (SNS) games from the perspectives of game usability and the functionality that is facilitated by the internet. Why players prefer SNS games to other types of games and what specific characteristics causes them to be addicted to continuous game play are the two critical issues to be probed.Design/methodology/approachThe authors interviewed 11 experts and surveyed 321 gamers using a questionnaire to gather the data about their preferences. The authors believe that a preference‐based study can reveal the underlying reasons for the appeal of SNS games. The collected data were analysed using Quantification Theory Type I.FindingsThe semantic structure of appeal, determined from the interviews of experts, shows the hierarchy of the relationship between the types of appeal or appeal factors, the reasons for gamers’ preferences, and the specific characteristics of SNS games. According to the statistical analysis, the three most important appeal factors of SNS games are “easy and convenient”, “friendly and lively” and “social interaction”, and these are affected in varying degrees by particular reasons and characteristics.Practical implicationsBased on the findings, the paper hypothesises that the popularity of Facebook SNS games can be ascribed to the design of game, which targets the psychological preferences of players.Originality/valueSNS games have become very popular due to some of their appealing characteristics. The findings provide important information for designers and researchers of Facebook SNS games. The study also contributes to the field of human‐computer interaction in cyberspace.
Service fairness and customer satisfaction in internet banking
Authors: Zhu Yu‐Qian , Chen Houn‐Gee 
Published: November 2014

PurposeThe purpose of this paper is to explore and empirically test fairness in predicting online customer satisfaction in the internet banking context. The paper also aims to further explore the mechanism through which fairness influences customer satisfaction online, i.e. identifying the mediators.Design/methodology/approachA survey is used to validate a research model based on equity theory and relationship marketing theory that incorporates fairness, trust, perceived value and customer satisfaction. A total of 331 surveys were analyzed using Partial Least Square.FindingsIn internet banking, fairness that includes distributive fairness, procedural fairness and informational fairness is positively related to customer satisfaction. Trust is identified as the key mediator of fairness to customer satisfaction.Research limitations/implicationsIn an online context, where human interactions are replaced by graphic user interfaces, fairness still plays an important role in customer satisfaction. Further comparison of online and offline context could be conducted.Practical implicationsFor online service managers, it is crucial to incorporate the fairness perspective into operations, which involves topics like segmented marketing efforts, consistency in procedures, and providing ample information to customers.Originality/valueThis research is one of the first attempts to examine fairness in internet banking, as well as to delineate the mediating process of fairness to satisfaction online.
