Maximum likelihood inference of reticulate evolutionary histories
Authors: Yu Yun , Dong Jianrong , Liu Kevin J. , Nakhleh Luay 
Published: November 2014

Significance
Phylogenetic trees play a central role in biology, modeling evolutionary histories of taxa ranging from genes, to genomes, and to species. Although trees will continue to be an essential modeling tool in evolution, phenomena such as hybridization, or gene flow more generally, result in evolutionary histories that are best modeled by phylogenetic networks. Inference of such networks is complicated by the presence of other evolutionary events, such as incomplete lineage sorting (ILS). Here, we provide a maximum likelihood method for inferring reticulate evolutionary histories while accounting for ILS. The method enables new evolutionary analyses under more complex evolutionary scenarios than existing methods can handle.

Significance
Governments spend billions of dollars each year managing invasive plant species. Many invasive plants have escaped from pastures and now degrade natural areas and transform ecosystems. New pasture taxa are promoted to help achieve sustainable intensification of agriculture by increasing production without using more land. However, plant characteristics that increase production also increase invasion risk. Combined with inadequate regulation and management to establish large feed-plant populations, new taxa will likely exacerbate problems with invasive species. Livestock production accounts for 30% of the world's land area. Risks associated with invasive feed-plants have been largely overlooked, even by studies explicitly critiquing the environmental risks of sustainable intensification. We suggest a suite of protocols to reduce these risks in sustainable intensification of agriculture.
Simple battery armor to protect against gastrointestinal injury from accidental ingestion
Authors: Laulicht Bryan , Traverso Giovanni , Deshpande Vikram , Langer Robert , Karp Jeffrey M. 
Published: November 2014

Significance
Accidental battery ingestion in children is a recognized source of significant morbidity and mortality. To mitigate the risks of accidental battery ingestion, legislation has been introduced to regulate the locking of battery compartments. Regulation of battery housings has translated into modest reductions in the number of battery ingestion cases reported. We report here the fabrication of waterproof, pressure-sensitive battery coatings that are nonconductive in the low-pressure gastrointestinal tract, yet conduct in higher-pressure standard battery housings. These safer batteries are expected to reduce complications from accidental battery ingestion.
Development of a grinding‐specific performance test set‐up
Authors: Olesen C. G. , Larsen B. H. , Andresen E. L. , de Zee M. 
Published: November 2014

AbstractThe aim of this study was to develop a performance test set‐up for America's Cup grinders. The test set‐up had to mimic the on‐boat grinding activity and be capable of collecting data for analysis and evaluation of grinding performance. This study included a literature‐based analysis of grinding demands and a test protocol developed to accommodate the necessary physiological loads. This study resulted in a test protocol consisting of 10 intervals of 20 revolutions each interspersed with active resting periods of 50 s. The 20 revolutions are a combination of both forward and backward grinding and an exponentially rising resistance. A custom‐made grinding ergometer was developed with computer‐controlled resistance and capable of collecting data during the test. The data collected can be used to find measures of grinding performance such as peak power, time to complete and the decline in repeated grinding performance.
Changes in the exploited demersal fish assemblages in the Southern Grand Banks (NAFO Divisions 3NO): 2002–2013
Authors: Nogueira Adriana , Paz Xabier , González-Troncoso Diana 
Published: November 2014

Abstract
The Newfoundland Shelf supported one of the world’s greatest fisheries until the main commercial species collapsed more than two decades ago. We calculated three ecological indices for individual populations and five for community from the data obtained in the research surveys conducted by Spain in NAFO Regulatory Area Divisions 3NO between 2002 and 2013. We use data for 24 species to study the dynamics of major demersal fish assemblages (38–300, 301–600, and 601–1460 m depth) and evaluated how they have responded to different levels of exploitation. Trends and changes for individual populations (abundance and biomass, intrinsic population rate of growth, and mean length) and for all the community (ABC curves, indices of faunal diversity, proportion of non-commercial species, mean length in community and size spectra) were used to test ecological trends. Indices showed no homogeneous status and responded to different exploitation patterns, management, and environmental regimes in each assemblage. Our results show an improvement in the shallower and deeper assemblages and that fishing effort does not explain differences among each assemblage.
Relationship building with students and instructors of ESL
Authors: Martin Julia A. , Reaume Kathleen M. , Reeves Elaine M. , Wright Ryan D. 
Published: November 2014

PurposeESL students often do not utilize the librarian for help or attend library orientation and instruction sessions. Academic librarians and ESL composition instructors need to bridge the gap in order to help guide international students during their academic career. This paper aims to address this issue.Design/methodology/approachThis paper will describe the benefits of relationship building between a librarian and two ESL instructors at the University of Toledo and the information literacy instruction sessions created for two ESL composition classrooms.FindingsThe paper finds that librarians and ESL instructors can bridge the gap for ESL students. Understanding the needs of the international/ESL community can help librarians approach ESL instructors or the international/ESL community in a way that allows the ESL student to feel comfortable and to seek out the librarian's assistance as new needs arise.Practical implicationsThe collaboration at the University of Toledo indicates that closer relationships are needed between librarians and ESL instructors and that more than one library session is needed to help ESL students feel comfortable with librarians and libraries.Social implicationsUnderstanding the culture, values, beliefs, and practices that ESL students bring from their home countries and exhibit in the composition classroom can help librarians create programs that help define library services and help to bridge the gap between services provided by the librarian and the ESL composition instructor.Originality/valueThe very strong relationship built between the librarian and the ESL instructors had a very positive affect not only in the initial trial, but also in developing part of the curriculum for ESL composition students. This paper has great potential value for both librarians who are interested in embedding themselves in ESL programs and for ESL instructors.
“It's research made easier!” SMS and chat reference perceptions
Authors: Ruppel Margie , Vecchione Amy 
Published: November 2014

PurposeThe purpose of this paper is to discover how college students perceive text messaging reference (SMS), chat reference, and face‐to‐face reference services.Design/methodology/approachThe authors administered surveys about chat, text messaging (SMS), and face‐to‐face reference to students enrolled in a one‐credit library skills course. Survey results focus on users' willingness to return, their perceptions of chat and text messaging (SMS) reference, and the reasons they choose to utilize different communication mediums for reference service.FindingsCollege students value the availability of high‐quality, quick, convenient, personalized reference assistance, regardless of medium used.Practical implicationsAcademic libraries can personalize reference services, but also need to offer ways for patrons to ask questions anonymously.Social implicationsRobust communication contributes to the perceived usefulness and success of library reference services. Effective reference service provided at the point‐of‐need helps build positive student‐librarian relationships.Originality/valueThis study aims to contribute to reference services research by bringing new technology into consideration. It focuses on two technologies (chat and SMS reference) in light of another available method (in‐person reference desk). This study is based on a 2002 study about patron perceptions of chat reference (Ruppel and Fagan), which is compared to the current study's results.
Immigration in America: library services and information resources
Authors: Wang Hong 
Published: November 2014

PurposeThis paper aims to present an overview of information resources that have been collected, prepared, or organized by librarians in support of information, reference and research needs pertaining to immigration and immigrants in the USA. The overview seeks to shed light on how American libraries have responded to the tides of immigration along with other community services to newcomers.Design/methodology/approachThe paper approaches the topic with a brief historical overview of immigration and library services. Through a comprehensive literature review the author intends to discover the degree to which American libraries have been involved in the provision of collections and services to immigrants.FindingsThe literature review indicates that the early decades of the twentieth century left a legacy of library services to immigrants with special patterns of collection development along with various organized programs. As time went by, these services have become more sophisticated and are today integrated into services of many public and academic libraries.Originality/valueThe paper provides perspectives on the social impact of immigration and immigrants – an issue which continues to challenge both public and academic libraries. The annotated bibliography contains items that are helpful to both reference personnel and researchers from academic fields and the general adult population.
An examination of best practices and benchmarking in corporate libraries
Authors: Simon Carol 
Published: November 2014

PurposeThis paper aims to discuss best practices in corporate libraries. It is limited to libraries within the USA and excludes medical, hospital, pharmaceutical and government libraries.Design/methodology/approachDefinitions of a corporate library and best practices are presented from the literature. The absence of generally accepted best practices within corporate libraries is noted and an explanation for its absence is presented.FindingsThe literature review indicates that there is an absence of generally accepted best practices within the corporate library community. This lack of quantitative data further weakens the position of corporate libraries within their organization as they cannot compare their operations to other service units. Corporate library managers must use the language and analysis tools of upper management to align the corporate library with the larger mission of the corporation to ensure its survival.Research limitations/implicationsThe absence of quantitative data focusing on corporate library services adversely impacts the future of corporate libraries. Until the professional association(s) representing the interests of corporate libraries develop, validate and administer a survey of corporate library services and costs, corporate librarians will remain at a competitive disadvantage when discussing the future of the corporate library.Originality/valueThe paper discusses best practices in corporate libraries.
Identifying the basis of collaboration performance in facility service business
Authors: Heimbürger Markku , Dietrich Perttu 
Published: November 2014

PurposeThe focus in the facility service business has traditionally been on operative level outcomes such as customer satisfaction and technical quality. These measures do not support business relationship management and co‐creative development. The article aims to propose a comprehensive theoretical framework to evaluate, develop, monitor and manage the collaborative business relation from both customer and service provider perspectives to co‐create mutual value.Design/methodology/approachThe theoretical framework for collaboration performance measurement is developed through empirical study of seven dyadic facility service procurement cases. Empirical study included 62 interviews of managers involved in relationship management on strategic, tactical and operative levels in both customer and service provider organizations.FindingsThe empirical study resulted following 13 measurement areas that indicate the collaboration performance in facility service procurement relation: customer benefits, supplier benefits, collaboration efficiency, operational fluency, conflicts recovery, flexibility and adaptability, execution capability, trust, actor incentive alignment, goal alignment and shared vision, strategic integrity, learning and development capability and uncertainty management. The article focuses on presenting the measurement areas of relational collaboration performance and discusses on their implications to performance measurement and management. Through this article the aim is to induce discussion on collaboration performance measurement and management, and challenge the colleague researchers and practitioners in the industry to comment and complement the proposed framework.Research limitations/implicationsThe results of the study introduce a new concept of collaboration performance and provide valuable and novel insight on related elements. The theoretical framework derived in this study is based on empirical data from facility services business and its suitability to a wider organizational context is not tested empirically in this study.Practical implicationsThe framework identified provides to both practitioners and researchers with an expanded viewpoint to measure and manage collaboration performance from both the service provider and customer sides.Originality/valueThe article proposes a new concept of collaboration performance and comprehensive theoretical framework for collaboration performance measurement and management.

Authors: Wu Shunxiang , Fu Changhong 
Published: November 2014

PurposeThe purpose of this paper lies in the combination of fuzzy set and interval grey set, namely, considering the fuzzy set theory, rough set theory and grey system theory. The paper then presents a unified form (or symbol system) which can be more useful to describe a wide variety of theories.Design/methodology/approachConsidering the lower bounds and upper bounds of interval grey set are classical set, this paper draws lessons from the classical set to fuzzy set transition mode which was advanced by Professor Zadeh. The paper puts forward the concept of interval fuzzy set, and then relaxes the constraints of the lower bound of interval fuzzy set to make it more widely used in actual uncertain problems.FindingsFor the examples which have been given in the paper, interval fuzzy set and its three theorems are proved practical and flexible.Practical implicationsThe theorems proved in the paper can be used as a useful extension to the classical fuzzy set, which can also be applied to fuzzy clustering, fuzzy classification, fuzzy pattern recognition and so on.Originality/valueThe paper puts forward the concept of interval fuzzy set and the three theorems of interval fuzzy set and proves their practicability and flexibility. The theorems can be used for further study on interval fuzzy set.

Authors: Li Size , Zhong Zhangdui , He Ruisi , Ai Bo 
Published: November 2014

PurposeThe purpose of this paper is to attempt to apply the theory of grey clustering evaluations in coal railway transportation on the “Datong‐Qinhuangdao” heavy haul railway line, to provide a reliable selection plan for heavy haul railway transportation.Design/methodology/approachGrey clustering evaluations are important contents of grey system. Starting from the investigation on the evaluations in coal railway transportation on the “Datong‐Qinhuangdao” line, the authors realize that the reasonable plan developed from the real equipment and wagon flow conditions for optimal organizing of trains to achieve minimum unloading time is becoming the goal of the organizing optimization. According to the theory of grey clustering evaluations, all the system parameters such as, transportation volume per year and cost of transportation, can be combined with each other through some methods. This allows the authors to apply the theory of grey clustering evaluations on the “Datong‐Qinhuangdao” heavy haul railway line, and provide a reliable selection plan for heavy haul railway transportation. The results of the statistical analysis can be used as the basic theory to serve the coal railway transportation, and are applicable to provide reliable transportation.FindingsThis paper presents the theory of grey clustering evaluations in coal railway transportation on “Datong‐Qinhuangdao” heavy haul railway line. The convincing results of the grey classes are reported, and can be used as the basic theory to provide reliable transportation.Practical implicationsThe method exposed in the paper can be used at each company's level for providing a reliable selection plan for heavy haul railway transportation. The results can also be used as the basic theory to provide reliable transportation.Originality/valueThe paper succeeds in providing a reliable selection plan for heavy haul railway transportation by using one of the newest developed theories: grey systems theory.
Shared video media and blogging online
Authors: Olofsson Anders D. , Ola Lindberg J. , Stödberg Ulf 
Published: November 2014

PurposeThe purpose of this paper is to provide an understanding of students' meaning‐making processes, as they are part of an e‐assessment practice via written blog posting upon their own, and their co‐students' performances, presented online through shared video media.Design/methodology/approachThe research relies on qualitative data to provide an analysis of students' use of the educational technology tool called VoiceThread©. These data were provided by collecting Swedish higher education students' postings and comments in relation to two video clips published in VoiceThread. The formal learning sequence model by Selander together with theories on communication and reflection were used in the analysis.FindingsThe data and the analysis show that shared video media and blogging embrace a potential to facilitate communication and reflection among online higher education students. In addition, the design of the course seems to strengthen the use of formative e‐assessment.Research limitations/implicationsThe research reported on in this paper should, preferably, be followed by additional research on educational technology, social software and e‐assessment; informed design of practices of formative e‐assessment; and the role of formative e‐assessment in the facilitating and enhancement of the students' learning and meaning‐making processes.Practical implicationsThis paper provides researched‐based ideas of ways in which teachers in online higher education can design their courses, if they want to cultivate the students' communicative and reflective skills.Originality/valueThis paper provides an important insight into the use of shared video media and blogging in online higher education, especially, the way it can be designed for within a formative e‐assessment course approach.
What do undergraduates study in heterodox economics programs? An examination of the curricula structure at 36 self‐identified programs
Authors: Nesiba Reynold F. 
Published: November 2014

PurposeThis paper aims to review the undergraduate curricular structure of 36 self‐identified heterodox economic programs in the USA, Australia, UK and Canada.Design/methodology/approachThe author gathers, summarizes, compares and contrasts the structure of 36 undergraduate heterodox departments. Departments are classified into traditional, plausibly pluralistic, and demonstrably heterodox programs. Specific examples illustrate each classification.FindingsWith notable exceptions described here, most heterodox economics programs are structured as traditional mainstream departments with a few pluralist or political economy electives available. However, 20 departments exist that require at least one heterodox course; eight require two or more.Practical implicationsA few programs have created imitable curricular structures that one would expect to significantly influence the depth and breadth of heterodox perspectives presented in the undergraduate economics major.Originality/valueThis is the first published analysis of undergraduate heterodox economics curricula. It highlights the creative structures characterizing some of the English‐speaking world's best programs and demonstrates that the curricula in most programs lack required courses in heterodox economics. The paper also provides examples of intentionally heterodox programs that may serve as models for others to emulate.
Heterodoxy in the classroom: the case of community economic development
Authors: Rosenbaum Rene P. 
Published: November 2014

PurposeThe article seeks to identify and examine HPE concepts and ideas that help teach community economic development to college students.Design/methodology/approachThe paper's discussion is situated within a descriptive account of the learning context, content and structure of a course on community economic development. Selected course readings are analyzed to identify heterodox concepts and to illustrate how they assist in helping students think critically about community economic development.FindingsThe course readings prove fruitful ground for the identification and examination of a range of heterodox concepts and ideas used to help students to think critically about community economic development issues.Research limitations/implicationsAlthough successful in examining the contributing roles of heterodoxy in teaching community economic development, the study relied on only one course syllabus.Practical implicationsThe article offers a practical way to gauge the use of heterodoxy in the classroom. It provides a case study example of how courses could be adopted to teach heterodox economic concepts and ideas.Originality/valueThe article presents a case study of the use of heterodoxy to help students think creatively and critically, and as such, provides an exemplar for other professors to adopt a similar approach.
