CSR in China Research: Salience, Focus and Nature
This article investigates the development of research in the field of CSR in China. The justification for this is that (i) there is evidence that CSR is emerging as a management practice and management field internationally; (ii) there is a general interest in the distinctiveness or comparability of management and management research in Asia and China; (iii) there is evidence that CSR is growing as a management issue in China; and (iv) yet, the mainsprings of this are very different from those in Western business systems. This article adopts a methodology used in wider analysis of CSR in management research (Lockett et al., Journal of Management Studies 43, 2006, 115) to bring forth comparisons over the salience, focus and nature of CSR in China research. It finds a rapidly growing salience of CSR in China research, albeit from a low base. It parallels Lockett et al.'s (2006) finding of a 'thickening' of CSR research focus from early concerns with Ethical issues only to greater attention to Social, Environmental and Stakeholder concerns. It also generally parallels Lockett et al.'s (2006) findings on the balance of research methodologies deployed. The significance of the findings for future CSR research in China is considered both for the notion of a CSR field of research and for our understanding of the development of CSR in China.

Begomovirus-Associated Satellite DNA Diversity Captured Through Vector-Enabled Metagenomic (VEM) Surveys Using Whiteflies (Aleyrodidae)
Monopartite begomoviruses (Geminiviridae), which are whitefly-transmitted single-stranded DNA viruses known for causing devastating crop diseases, are often associated with satellite DNAs. Since begomovirus acquisition or exchange of satellite DNAs may lead to adaptation to new plant hosts and emergence of new disease complexes, it is important to investigate the diversity and distribution of these molecules. This study reports begomovirus-associated satellite DNAs identified during a vector-enabled metagenomic (VEM) survey of begomoviruses using whiteflies collected in various locations (California (USA), Guatemala, Israel, Puerto Rico, and Spain). Protein-encoding satellite DNAs, including alphasatellites and betasatellites, were identified in Israel, Puerto Rico, and Guatemala. Novel alphasatellites were detected in samples from Guatemala and Puerto Rico, resulting in the description of a phylogenetic clade (DNA-3-type alphasatellites) dominated by New World sequences. In addition, a diversity of small (~640–750 nucleotides) satellite DNAs similar to satellites associated with begomoviruses infecting Ipomoea spp. were detected in Puerto Rico and Spain. A third class of satellite molecules, named gammasatellites, is proposed to encompass the increasing number of reported small (<1 kilobase), non-coding begomovirus-associated satellite DNAs. This VEM-based survey indicates that, although recently recovered begomovirus genomes are variations of known genetic themes, satellite DNAs hold unexplored genetic diversity.

What is the Eisenhardt Method, really?
This essay sharpens and refreshes the multi-case theory-building approach, sometimes termed The “Eisenhardt Method.” The Method’s singular aim is theory building, especially with multiple cases and theoretical logic. Its defining features (e.g. research questions without obvious answers, careful case selection, well-identified constructs and relationships, theoretical arguments, boundary conditions) reflect this aim. I begin with the influence of the 1980s, including grounded theorizing and case logic. Relying on exemplars, I illustrate the Method’s defining features. I also address common misconceptions (e.g. types of data, number of cases, performance emphasis). These miss the Method’s essence and imply a rigid template that does not exist. Instead, the Method’s relatively few defining features enable a wide variety of research possibilities. I conclude with what I would write today like a richer palette of research choices, more emphasis on time, and flexible philosophy of science. Yet the core message of theory building would remain.

\The Camera Rolls\: Using Third-Party Video in Field Research
This article draws on one citizen's efforts to document daily life in his neighborhood. The authors describe the potential benefits of third-party video—videos that people who are not social scientists have recorded and preserved—to social science research. Excerpts from a collection of police-citizen interactions illustrate key points likely to confront researchers who use third-party video. The authors address two important questions: How might the presence of a video camera affect the unfolding of interactions that are recorded in third-party videos? and How might the perspective of the videographer influence the production and preservation of these records and, in turn, what influence might this standpoint have on our analysis of the data? The authors argue that, given the ubiquity of handheld video recording devices, social scientists should develop systematic approaches to using video created by others as both a cultural record and as data.

High Magnetic Field Science and Its Application in the United States
The Committee to Assess the Current Status and Future Direction of High Magnetic Field Science in the United States was convened by the National Research Council in response to a request by the National Science Foundation. This report answers three questions: (1) What is the current state of high-field magnet science, engineering, and technology in the United States, and are there any conspicuous needs to be addressed? (2) What are the current science drivers and which scientific opportunities and challenges can be anticipated over the next ten years? (3) What are the principal existing and planned high magnetic field facilities outside of the United States, what roles have U.S. high field magnet development efforts played in developing those facilities, and what potentials exist for further international collaboration in this area?
A magnetic field is produced by an electrical current in a metal coil. This current exerts an expansive force on the coil, and a magnetic field is \"high\" if it challenges the strength and current-carrying capacity of the materials that create the field. Although lower magnetic fields can be achieved using commercially available magnets, research in the highest achievable fields has been, and will continue to be, most often performed in large research centers that possess the materials and systems know-how for forefront research. Only a few high field centers exist around the world; in the United States, the principal center is the National High Magnetic Field Laboratory (NHMFL).
High Magnetic Field Science and Its Application in the United States considers continued support for a centralized high-field facility such as NHFML to be the highest priority. This report contains a recommendation for the funding and siting of several new high field nuclear magnetic resonance magnets at user facilities in different regions of the United States. Continued advancement in high-magnetic field science requires substantial investments in magnets with enhanced capabilities. High Magnetic Field Science and Its Application in the United States contains recommendations for the further development of all-superconducting, hybrid, and higher field pulsed magnets that meet ambitious but achievable goals.

Measurement Instruments for the Anthropomorphism, Animacy, Likeability, Perceived Intelligence, and Perceived Safety of Robots
This study emphasizes the need for standardized measurement tools for human robot interaction (HRI). If we are to make progress in this field then we must be able to compare the results from different studies. A literature review has been performed on the measurements of five key concepts in HRI: anthropomorphism, animacy, likeability, perceived intelligence, and perceived safety. The results have been distilled into five consistent questionnaires using semantic differential scales. We report reliability and validity indicators based on several empirical studies that used these questionnaires. It is our hope that these questionnaires can be used by robot developers to monitor their progress. Psychologists are invited to further develop the questionnaires by adding new concepts, and to conduct further validations where it appears necessary.

Genetic correlations and genome-wide associations of cortical structure in general population samples of 22,824 adults
Cortical thickness, surface area and volumes vary with age and cognitive function, and in neurological and psychiatric diseases. Here we report heritability, genetic correlations and genome-wide associations of these cortical measures across the whole cortex, and in 34 anatomically predefined regions. Our discovery sample comprises 22,824 individuals from 20 cohorts within the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium and the UK Biobank. We identify genetic heterogeneity between cortical measures and brain regions, and 160 genome-wide significant associations pointing to wnt/β-catenin, TGF-β and sonic hedgehog pathways. There is enrichment for genes involved in anthropometric traits, hindbrain development, vascular and neurodegenerative disease and psychiatric conditions. These data are a rich resource for studies of the biological mechanisms behind cortical development and aging.
Cortex morphology varies with age, cognitive function, and in neurological and psychiatric diseases. Here the authors report 160 genome-wide significant associations with thickness, surface area and volume of the total cortex and 34 cortical regions from a GWAS meta-analysis in 22,824 adults.

Reproducible Research in Computational Science
Computational science has led to exciting new developments, but the nature of the work has exposed limitations in our ability to evaluate published findings. Reprodudbility has the potential to serve as a minimum standard for judging scientific claims when full independent replication of a study is not possible.

Field research in conflict environments: Methodological challenges and snowball sampling
Conducting research in conflict environments is a challenge, given their complexity and common attitudes of distrust and suspicion. Yet, conflict and methodology are usually analyzed as separate fields of interest. Methodological aspects of field work in conflict environments have not been systematically analyzed. This article addresses the central methodological problems of research conducted in conflict environments. We suggest the use of the snowball sampling method (hereafter, SSM) as an answer to these challenges. The effectiveness of this method has been recognized as significant in a variety of cases, mainly regarding marginalized populations. We claim that in conflict environments, the entire population is marginalized to some degree, making it 'hidden' from and 'hard to reach' for the outsider researcher. The marginalization explains why it is difficult to locate, access and enlist the cooperation of the research populations, which in a non-conflict context would not have been difficult to do. SSM directly addresses the fears and mistrust common to the conflict environment and increases the likelihood of trusting the researcher by introduction through a trusted social network. We demonstrate how careful use of SSM as a 'second best' but still valuable methodology can help generate cooperation. Therefore, the evaluation of SSM, its advantages and limitations in implementation in conflict environments can be an important contribution to the methodological training of researchers. In addition to its effectiveness under conditions of conflict, SSM may, in some cases, actually make the difference between research conducted under constrained conditions and research not conducted at all. Together with our experiences in the field, we supply several insights and recommendations for optimizing the use of SSM in a conflict environment.
