Abstract
The massive influx of crude oil into the Gulf of Mexico during the Deepwater Horizon (DWH) disaster triggered dramatic microbial community shifts in surface oil slick and deep plume waters. Previous work had shown several taxa, notably DWH Oceanospirillales, Cycloclasticus and Colwellia, were found to be enriched in these waters based on their dominance in conventional clone and pyrosequencing libraries and were thought to have had a significant role in the degradation of the oil. However, this type of community analysis data failed to provide direct evidence on the functional properties, such as hydrocarbon degradation of organisms. Using DNA-based stable-isotope probing with uniformly 13C-labelled hydrocarbons, we identified several aliphatic (Alcanivorax, Marinobacter)- and polycyclic aromatic hydrocarbon (Alteromonas, Cycloclasticus, Colwellia)-degrading bacteria. We also isolated several strains (Alcanivorax, Alteromonas, Cycloclasticus, Halomonas, Marinobacter and Pseudoalteromonas) with demonstrable hydrocarbon-degrading qualities from surface slick and plume water samples collected during the active phase of the spill. Some of these organisms accounted for the majority of sequence reads representing their respective taxa in a pyrosequencing data set constructed from the same and additional water column samples. Hitherto, Alcanivorax was not identified in any of the previous water column studies analysing the microbial response to the spill and we discuss its failure to respond to the oil. Collectively, our data provide unequivocal evidence on the hydrocarbon-degrading qualities for some of the dominant taxa enriched in surface and plume waters during the DWH oil spill, and a more complete understanding of their role in the fate of the oil.
A Demographic Study of AAC/AT Needs in Hospitalized Patients
Authors: Zubow Lauren , Hurtig Richard 
Published: June 2013

Abstract
In 2012, the Joint Commission issued a mandate that accredited hospitals must take into consideration the needs of patients with complex communication needs. Stemming from this mandate came recommendations for hospitals to collect baseline data of the number of individuals in their care with complex communication needs. This is a demographic study in response to their recommendation. Researchers at the University of Iowa sampled the electronic medical records of patients across 7 days to determine the number of patients who met candidacy requirements for augmentative alternative communication or assistive technology. Our census data indicate there is a significant need for patients in acute care settings to have access to alternative communication and the nurse call systems. The need appears to be greater in the intensive care units, but is not limited to this patient population. Overall, patients had greater AT needs than AAC needs in all locations. We recommend future research to investigate service delivery models to improve communication barriers that may exist between hospital staff and patients.
A Sensitive and Accurate protein domain cLassification Tool (SALT) for short reads
Authors: Zhang Yuan , Sun Yanni , Cole James R. 
Published: June 2013

Abstract
Motivation: Protein domain classification is an important step in functional annotation for next-generation sequencing data. For RNA-Seq data of non-model organisms that lack quality or complete reference genomes, existing protein domain analysis pipelines are applied to short reads directly or to contigs that are generated using de novo sequence assembly tools. However, these strategies do not provide satisfactory performance in classifying short reads into their native domain families.
Results: We introduce SALT, a protein domain classification tool based on profile hidden Markov models and graph algorithms. SALT carefully incorporates the characteristics of reads that are sequenced from the domain regions and assembles them into contigs based on a supervised graph construction algorithm. We applied SALT to two RNA-Seq datasets of different read lengths and quantified its performance using the available protein domain annotations and the reference genomes. Compared with existing strategies, SALT showed better sensitivity and accuracy. In the third experiment, we applied SALT to a non-model organism. The experimental results demonstrated that it identified more transcribed protein domain families than other tested classifiers.

Downy Mildew from Lake Erie Vineyards is Diverse for the G143A SNP Conferring Resistance to Quinone Outside Inhibitor Fungicides
Authors: Gee Christopher T. , Chestnut Stephanie , Duberow Eilene , Collins Andrea , Shields Michael A. 
Published: June 2013

Downy mildew (Plasmopara viticola) is a significant problem in grape vineyards throughout the growing season. Control of downy mildew is carried out with a combination of host tolerance and chemical applications. Even in vineyards planted with very tolerant varieties (e.g., Concord), control is important in years with ideal pathogen conditions. Fungicides with a single mode of action possess a very high potential for the development of resistance. Resistance has been observed often in the Quinone outside inhibitor (QoI) fungicides, such as strobilurins. We ascertained the levels of QoI resistance in downy mildew colonies on diseased leaves using CAPS-PCR to detect the glycine to alanine mutation (G143A) known to confer a qualitative level of resistance in fungal pathogens. Our data uncovered a small percentage of samples that contain G143A, suggesting an overall low level of QoI resistance. The low prevalence of the resistant single nucleotide polymorphism (SNP) suggests that QoI fungicides should remain a viable control mechanism in Lake Erie vineyards. Additionally, it appears that a viticultural region where tolerant hosts predominant and QoI use is minimal, resistance buildup in the pathogen population will be minimal.

Business school culture: customer‐focused, virtual and cooperative
Authors: Lorange Peter 
Published: June 2013

PurposeThe purpose of this paper is to examine and question aspects of the culture of the modern business school, and to investigate the possibilities for a more student oriented, more responsive, more flexible and performance‐driven culture.Design/methodology/approachThe paper is a critical discourse on the cultural conservatism of contemporary business schools, analysing the impediments to change, and examining the transformation in the business education market and among students, that demand greater responsiveness.FindingsThe paper finds that while the traditional culture of business schools is deeply embedded in professional practices and axiomatic disciplines, the seismic changes occurring in technology and social practices beyond the business school are impelling business schools to adapt and become more agile.Research limitations/implicationsWhile recognising the significance of the changes that are already occurring, it also acknowledged that there is a deeply embedded set of professional and cultural practices in university business schools that are long established and will not be readily changed, with more likely an ongoing tension between modernity and tradition.Practical implicationsThe paper provides insights into how a more flexible and responsive business school would operate and engage students.Originality/valueThe paper provides a fresh assessment of where the business schools are, and where they will have to go to continue to engage the changing demands of business and managers.
Reputational challenges for business schools: a contextual perspective
Authors: Siebert Sabina , Martin Graeme 
Published: June 2013

PurposeThe dominant variance theory approaches to researching business school reputations are based on a positivistic hypothetico‐deductive research methodology and do not adequately take into account either the different levels and types of contexts in which business schools operate or the diversity of stakeholder interests. The aim of this paper is to propose a more relevant contextualised framework for analysing the reputation of business schools that takes cognisance of the national business systems, industry/sector, university and relational contexts of the different stakeholders involved in socially constructing and enacting business school reputations. The authors also seek to explore the tensions between these often competing or unaligned agendas of stakeholders in business schools.Design/methodology/approachThis is a conceptual paper that proposes a contextualised framework for analysing the reputation of business schools. It reviews the current state of theory on business schools’ reputations, analyses their weaknesses and potential research gaps, and proposes an alternative model to the dominant universalistic positivism in understanding business school reputations.FindingsThe authors conclude that the variance theory underpinning of current research does not take into account sufficiently either the diversity of stakeholder interests or the contexts in which business schools operate. Thus, the authors propose an alternative model to the dominant universalistic positivism in understanding business school reputations. This new model is based on four levels of context: national, industry, university and relational, and acknowledges that different stakeholders might have a dominant voice at each of these levels.Originality/valueThe authors attempt to fill a gap in the existing literature on business school reputations, and make a contribution to theory of reputation management.
The future of family business education in UK business schools
Authors: Collins Lorna , Seaman Claire , Graham Stuart , Stepek Martin 
Published: June 2013

PurposeThis practitioner paper aims to question basic assumptions about management education and to argue that a new paradigm is needed for UK business schools which embraces an oft neglected, yet economically vital, stakeholder group, namely family businesses. It seeks to pose the question of why we have forgotten to teach about family business management in the management portfolio.Design/methodology/approachThe paper adopts a stakeholder approach, building on nominal stakeholder theory to justify a change to the teaching paradigm in business schools. It builds on discussions in the extant literature about failures of business schools to address modern needs.FindingsThe authors find that business schools in the UK need to begin to engage with family businesses through embracing the next generation from families in business. Policy needs to be developed that will support the next generation in a positive way by teaching about the family in business.Originality/valueThe paper aims to stimulate discussion about key stakeholders and prompt review of neglect of this key area of business study in the UK.
Green marketing in B2B organisations: an empirical analysis from the natural‐resource‐based view of the firm
Authors: Fraj Elena , Martínez Eva , Matute Jorge 
Published: June 2013

PurposeFollowing the natural resource based view of the firm, this paper seeks to analyse the influence of a green marketing strategy on the performance of business‐to‐business organisations. Also, it aims to explore the role of organisational resources as drivers of proactive environmental management.Design/methodology/approachA model based on structural equations with partial least squares analysis is used to test the hypotheses. This model was tested on a sample of 181 industrial organisations.FindingsThe findings confirm that managers indirectly play a key role in the design and development of green marketing strategies through the integration of environmental values into the organisational culture. They also reveal that, while market‐oriented practices directly determine economic performance, internally oriented activities indirectly influence financial results through the improvement of the firm's environmental performance.Research limitations/implicationsThis research partially integrates organisational resources as drivers of environmental behaviour, and does not explore the role of capabilities. The article proposes different implications considering the competitive consequences of a green marketing strategy.Practical implicationsThe article includes different practical implications about the effect of different environmental practices on different dimensions of organisational performance. It sheds light on the controversial link between environmental proactivity and performance.Originality/valueThis research tests empirically some of the theoretical underpinnings of the natural resource based view of the company in an under‐researched context like the business‐to‐business context.
Improving accountability through expanded measures of performance
Authors: Hamilton Laura S. , Schwartz Heather L. , Stecher Brian M. , Steele Jennifer L. 
Published: June 2013

PurposeThe purpose of this paper is to examine how test‐based accountability has influenced school and district practices and explore how states and districts might consider creating expanded systems of measures to address the shortcomings of traditional accountability. It provides research‐based guidance for entities that are developing or adopting new measures of school performance.Design/methodology/approachThe study relies on literature review, consultation with expert advisers, review of state and district documentation, and semi‐structured interviews with staff at state and local education agencies and research institutions.FindingsThe research shows mixed effects of test‐based accountability on student achievement and demonstrates that teachers and administrators change their practices in ways that respond to the incentives provided by the system. The review of state and district measurement systems shows widespread use of additional measures of constructs, such as school climate and college readiness.Research limitations/implicationsThere is a clear need for additional research on the short‐ and long‐term effects of expanded systems of measures. In particular, currently little is known about how the inclusion of input and process measures influences educators’ practices or student outcomes.Practical implicationsThe research suggests several practical steps that can be taken to promote effective systems of measurement, including providing supports for high‐quality teaching to accompany new measures, offering flexibility to respond to local needs, and conducting validity studies that address the various purposes of the measures.Originality/valueThe paper provides new information about how states and districts are expanding their systems of measures for various purposes, and informs accountability policy by highlighting the benefits and limitations of current outcomes‐based approaches to accountability and by clarifying the trade‐offs and decisions that should be considered.
Systemwide reform under pressure: a global perspective on learning and change
Authors: Stoll Louise 
Published: June 2013

PurposeThe purpose of this paper is to present the author's commentary on the special issue of Journal of Educational Administration entitled “Systemwide reform: examining districts under pressure”.Design/methodology/approachIn framing her reflections, the author has looked across the five articles in the special issue, pulling out a number of themes from the perspective of her interest in capacity for learning. This interest stems from involvement over many years in research and development in school improvement and its leadership, and the conclusion that real and meaningful educational change requires much more than superficial tinkering with structures and practices in schools and districts.FindingsThe author's comments draw heavily from her own context, England where, it could be argued, an educational policy “experiment” is taking place but she also refers to other countries’ approaches and experiences.Originality/valueThe author's own work is underpinned by social and organizational learning theories, and so she welcomes the diversity of theoretical and methodological perspectives taken by the authors in this special issue in helping to view the special issue topic from different angles.
Research watch: art therapy: a dose of treatment, an aid to social inclusion or an unnecessary indulgence?
Authors: Holttum Sue 
Published: June 2013

PurposeThis Research Watch aims to summarise two recent and very different research publications on art therapy and comments on their ability to shed light on the usefulness of art therapy to address mental distress and enhance social inclusion.Design/methodology/approachThe author discusses a recent edition of a UK art therapy journal in which research papers focus on art therapy with people who have been given a diagnosis of personality disorder. The main methodologies are qualitative describing participants’ and/or therapists’ experiences and the role of art therapy in addressing serious mental distress. The second publication is a recent report of a large randomised controlled trial of art therapy for people given a diagnosis of schizophrenia. The author assesses the value of both publications in informing us about the usefulness of art therapy in addressing mental distress and enhancing social inclusion.FindingsIn the author's view, neither publication establishes definitively how or whether art therapy might address serious mental distress, whether labelled personality disorder or schizophrenia. However, the qualitative articles provide insight into possible helpful (and less helpful) aspects of therapy. The randomised trial should have been able to establish general principles about the effectiveness of art therapy for a specific group of people in specified contexts, but instead exemplifies many problems inherent in the pervasive research culture of putting numbers onto complex human interactions and calculating their value for money, sometimes at the expense of really understanding what is going on.Originality/valueThe author draws upon these two very different examples of research to reflect a current dilemma in UK art therapy research, and tentatively looks at possible ways forward.
Comparison of propensity for carbon disclosure between developing and developed countries
Authors: Luo Le , Tang Qingliang , Lan Yi‐Chen 
Published: June 2013

PurposeThe purpose of this paper is to investigate differences in voluntary carbon disclosure between developing and developed countries and the role of resource availability in explaining these differences.Design/methodology/approachThe authors used a sample consisting of 2,045 large firms from 15 countries and representing divergent industries that released Carbon Disclosure Project (CDP) company reports in 2009. Profitability, leverage and growth were used as proxies for the degree of resource availability and the firm's participation in the CDP was used as a proxy for carbon disclosure propensity.FindingsConsistent with the authors' predictions, the empirical results show that the carbon disclosure propensity is correlated in the right direction with resource availability proxies; this relationship is stronger in developing nations, suggesting that the shortage of resources is one reason for the lack of commitment to carbon mitigation and disclosure in these countries. The results are robust when disclosure motivation proxies are controlled for. In addition, it is shown that firms tend to disclose carbon information if their shares are owned by CDP signatories, because it allows them to be viewed as more powerful stakeholders. This finding, which enhances the validity of stakeholder theory, previously has not been documented in the literature.Research limitations/implicationsThe findings are relevant to the world's largest organisations, as determined by their market capitalisation. Thus, caution should be exercised to generalise the paper's inferences to small or medium‐sized organisations.Practical implicationsThe evidence suggests that resource shortages may constrain a firm management's carbon decisions. As the regulatory environment becomes more stringent, firms, particularly those in developing countries need to take a more proactive strategy to tackle global warming challenges and balance the need to achieve financial goals and prevent carbon pollution with their limited resources.Originality/valueAlthough prior studies typically considered external pressures that motivated voluntary environmental disclosure, the paper's results offer extra insight and suggest that resource restriction provides a complementary explanation – largely ignored in the existing literature – for variation in the carbon‐disclosure propensity of firms.
Audit quality and overvalued equity
Authors: Houmes Robert , Foley Maggie , Cebula Richard J. 
Published: June 2013

PurposeAudit quality studies document that accruals decrease when the audit firm is large, or the audit firm is an industry specialist, or the audit‐client tenure is long. The purpose of this paper is to posit that incentives related to highly‐valued equity mitigate these results, as managers use income increasing accruals to augment earnings.Design/methodology/approachTo test this assertion, the authors regress discretionary accruals on: controls, a highly valued equity indicator variable equal to 1 if the client's lagged price‐to‐earnings ratio is in the highest P/E quintile, indicator variables equal to 1 for alternative measures of audit quality, and interaction terms between the highly valued equity indicator variable and audit quality indicator variables.FindingsResults of tests show positive and statistically significant coefficients for each of the highly‐valued equity‐audit quality interaction terms, suggesting that when a firm is highly valued the accruals' decreasing effect of high quality auditors is reduced.Originality/valueBeginning with Jensen's article regarding the agency costs of overvalued equity, a stream of research examining factors associated with highly priced firms has developed. The paper extends these findings, as well as the considerable body of audit quality studies, by examining the ability of a high quality auditor to attenuate this result.
