Mentoring the morally courageous: a relational cultural perspective
Authors: Simola Sheldene 
Published: August 2016

Purpose
The purpose of this paper is to elucidate the implications of relational cultural theory (RCT) for mentoring individuals who have enacted moral courage.

Design/methodology/approach
Overviews of the construct of moral courage, the nature of work-related mentoring and RCT are provided. Subsequently, the relevance and implications of RCT for understanding moral courage-related suffering, and for supporting the growth, resilience and vitality of those who have enacted moral courage are discussed.

Findings
Within RCT, moral courage-related suffering is located in disconnection, invalidation and isolation for which sufferers also feel held at fault. Self-protective behaviors, including disavowal of self, can perpetuate this suffering.

Practical implications
Five insights from RCT for supporting the growth, resilience and vitality of individuals following acts of moral courage are elaborated, including affirming efforts to activate supportive relationships; demonstrating “radical respect”; facilitating voice; engaging through mutuality and fluid expertise; and, reframing resilience.

Social implications
The dearth of attention to ways of supporting those who suffer following acts of moral courage reflects previously documented findings about the short-shrift given to issues of human health and sustainability in organizations and organizational research. Implications for policy, practice and education are described.

Originality/value
This paper extends the RCT perspective in mentoring, and addresses an important gap in the moral courage literature, namely, the identification of a theoretically grounded approach through which to support the growth, resilience and vitality of individuals who have enacted moral courage.
Proactive personality and citizenship performance
Authors: Jawahar I.M. , Liu Yongmei 
Published: August 2016

PurposeThe purpose of this paper is to examine the moderating role of political skill in the relationship between proactive personality and citizenship performance, as mediated by career satisfaction.Design/methodology/approachThe authors collected data from a diverse sample of 356 employees, and tested a moderated mediation model, in which proactive personality and political skill jointly impact career satisfaction, which in turn impacts citizenship performance.FindingsThe results indicate that career satisfaction mediates the relationship between proactive personality and two forms of citizenship performance, citizenship toward supervisor, and job/task conscientiousness. Political skill moderates these mediated relationships such that proactive individuals who are also politically skilled are more likely to demonstrate greater citizenship toward supervisor and job/task conscientiousness via increased career satisfaction.Research limitations/implicationsThe study suggests that proactive employees, due to their enhanced career satisfaction, tend to demonstrate greater organizational citizenship. Such positive tendencies are enhanced when proactive employees are equipped with political skill. Limitations include the use of cross-sectional design and single source data.Practical implicationsOrganizations and human resources managers should be aware of the importance of personal career satisfaction and interpersonal competency in building organizational citizenship. Organizations may facilitate citizenship performance by recruiting individuals high in proactive personality and political skill.Originality/valuePrior research has typically considered career satisfaction as an outcome variable. The authors examine career satisfaction as an intermediate variable leading to citizenship performance. The authors also examine the contingent effect of proactive personality.

Purpose
The aging workforce is becoming an increasingly important topic in today’s labor market. However, most scientific research and organizational policies focus on chronological age as the main determinant of successful aging. Based on life span developmental theories – primarily socioemotional selectivity theory and motivational theory of life span development – the purpose of this paper is to test the added value of using subjective age – in terms of remaining opportunities and remaining time – over and above chronological age in their associations with motivation at work and motivation to work.

Design/methodology/approach
Workers from five different divisions throughout the Netherlands (n=186) from a taxi company participated in the survey study.

Findings
The results from the regression analyses and structural equation modeling analyses support the hypotheses: when subjective age was included in the models, chronological age was virtually unrelated to workers’ intrinsic motivation, extrinsic motivation, and motivation to continue to work for one’s organization. Moreover, subjective age was strongly related to work motivation. Specifically, workers who perceived many remaining opportunities were more intrinsically and extrinsically motivated, and those who perceived a lot of remaining time were more motivated across the board.

Originality/value
The findings indicate that subjective age is an important concept to include in studies focussing on successful aging, thereby contributing to life span developmental theories. Further implications for research and practice are discussed.

Published: August 2016

Subject area
“Starting up a new company” and “development of technology-based venture”.

Study level/applicability
The target audiences for this study are advanced business or non-business undergraduate students and MBA students taking courses of entrepreneurship, management of innovation and organization theory and design.

Case overview
Yeayyy.com was a private limited company based in Bandar Baru Bangi, Selangor, a township located about 30 km south of Kuala Lumpur. It was founded by Mr Hazmin in early 2010 with a seed funding of RM150,000 (about US$50,000). By the end of 2014, its core businesses include developing mobile application (app), software and website, as well as conducting information technology (IT) training. The company had developed its own animation cartoon, Oolat Oolit, and had commercialized several mobile app inventions. These mobile apps include a Jawi (traditional Malay writing system) app, mobile games and Facebook apps which were compatible with most mobile operating systems. Since its inception, Yeayyy.com had aspired to follow the footsteps of the internationally acclaimed Malaysian home-grown animation production house, Les’ Copaque, which had produced the popular Upin Ipin series. Similar to Les’ Copaque, Yeayyy.com also planned to commercialize its in-house characters into TV series and to market related merchandises, along with its collaborative partner, CikuTree Studio. However, by the end of 2014, the company’s seed funding had depleted, thus forcing Mr Hazmin to strategize for the company’s future.

Expected learning outcomes
Understanding the process of entrepreneurship and technology-based venture development enables case analysts to apply the concepts in many situations involving business opportunities and company development.

Integrating AR services for the masses: geotagged POI transformation platform
Authors: Trojan Jakub 
Published: August 2016

Purpose
The purpose of this paper is to propose the platform for effective transformation of points of interests (POIs) into augmented reality (AR), specifically into the three major software tools – Junaio, Layar and Wikitude. The objective is to facilitate the creation of POIs for common users of these programs and, thus, encourage the general public to participate in the formation of a new concept of applications using AR and location-based services.

Design/methodology/approach
The subject of this study was analysis of methods used for POI dynamisation under the context of location-based services. This paper suggests methodology based on database format transformation. It is focused on the creation of platform for automated geotagged POI transformation into AR.

Findings
The research results in prototype of online platform which is capable to automatically transform geotagged POI to three major AR applications. It discusses also the model implementation of this platform in Czech national tourist authority.

Research limitations/implications
The paper presents a proof-of-concept of dynamisation and transformation of an unspecified number of POIs stored in a simple table database and their transformation into the AR.

Practical implications
Services of AR are brought for the masses to effectively dynamise tourist information.

Social implications
Results could make the process of multimedialising data (POIs) more suitable for masses.

Originality/value
This paper presents a proof-of-concept of dynamisation and transformation of an unspecified number of POIs stored in a simple table database and their transfer into the three major AR applications.
Hip-hop based interventions as pedagogy/therapy in STEM
Authors: Emdin Christopher , Adjapong Edmund , Levy Ian 
Published: August 2016

Purpose
This paper aims to argue that providing youth of color with opportunities to explore content while reflecting on and sharing mental health concerns is an under-focused dimension of teaching and learning that has the potential to positively impact these students’ academic achievement in science, technology, engineering and mathematics (STEM) disciplines

Design/methodology/approach
This paper used a qualitative study to interrogate a teaching/learning model through a hip-hop-based science program.

Findings
Because urban youth of color are traditionally most disengaged in STEM and also the ones who are the least likely to seek or be provided with mental health tools/services, it is suggested that there is a connection between their low academic achievement and the absence of opportunities for them to address emotions that impact their academic success. Furthermore, if these youths come from communities where mental health stressors are highly prevalent, and teaching is most restrictive, a model for teaching that considers practices that address both their academic and mental health needs becomes necessary.

Research limitations/implications
This work does not intend to devalue or undermine the role of school counselors or traditional teachers. It is believed that the role of the school counselor or social worker when youths identify themes that go beyond the scope of personal challenges is significant and that these professionals should be made available when engaging in this type of work. It is also believed that the educator who may not be privy to hip-hop can successfully engage in this type of activity with STEM students. Finally, the use of science as an exemplar for engaging in this work does not indicate that the other STEM disciplines cannot or should not explore this type of model.

Practical implications
The paper outlines a model that other educators/researchers may use and suggests ways that this brand of research may be implemented by scholars across the country.

Social implications
Through the implementation of the hip-hop-based science program as an intervention in science classrooms, students are provided the opportunity to bolster science content knowledge and knowledge of self. In addition, utilizing the hip-hop-based science program created an avenue for teachers to develop better understanding of students and their full socioemotional selves. This is especially necessary in STEM education where perceptions of students’ decisions to not engage in the disciplines are directly related to our collective unwillingness to present the subject matter in a way that goes beyond the glorification of its stoic and “old white” history.

Originality/value
This paper suggests a new dimension of STEM research through an exploration of hip-hop culture and youth emotions.
Enabling affordable omnidirectional subsurface extended image volumes via probing
Authors: van Leeuwen Tristan , Kumar Rajiv , Herrmann Felix J. 
Published: August 2016

ABSTRACTImage gathers as a function of subsurface offset are an important tool for the inference of rock properties and velocity analysis in areas of complex geology. Traditionally, these gathers are thought of as multidimensional correlations of the source and receiver wavefields. The bottleneck in computing these gathers lies in the fact that one needs to store, compute, and correlate these wavefields for all shots in order to obtain the desired image gathers. Therefore, the image gathers are typically only computed for a limited number of subsurface points and for a limited range of subsurface offsets, which may cause problems in complex geological areas with large geologic dips. We overcome increasing computational and storage costs of extended image volumes by introducing a formulation that avoids explicit storage and removes the customary and expensive loop over shots found in conventional extended imaging. As a result, we end up with a matrix–vector formulation from which different image gathers can be formed and with which amplitude‐versus‐angle and wave‐equation migration velocity analysis can be performed without requiring prior information on the geologic dips. Aside from demonstrating the formation of two‐way extended image gathers for different purposes and at greatly reduced costs, we also present a new approach to conduct automatic wave‐equation‐based migration‐velocity analysis. Instead of focusing in particular offset directions and preselected subsets of subsurface points, our method focuses every subsurface point for all subsurface offset directions using a randomized probing technique. As a consequence, we obtain good velocity models at low cost for complex models without the need to provide information on the geologic dips.

Published: August 2016

Cheeses containing Agave fructans were compared with both full‐fat and reduced‐fat samples without fructans. Microstructure results showed that the cheeses obtained were very similar to the control samples (without fructans), even the full‐fat control sample, demonstrating the texturing role of the carbohydrates. Regarding the composition, a moisture content of 47.96 ± 1.45 and a good protein retention with a low‐fat content were found. Therefore, the cheese yield was not adversely affected, and no significant differences were observed in sensory aspects. Considering the health benefits of fructans and their abundance, this development could represent an innovation for dairy industry.
Review article: Why is there still a debate regarding the safety and efficacy of intravenous thrombolysis in the management of presumed acute ischaemic stroke? A systematic review and meta‐analysis
Authors: Donaldson Lachlan , Fitzgerald Emily , Flower Oliver , Delaney Anthony 
Published: August 2016

AbstractObjectiveThe objective of the present study is to independently and systematically assess the harms and benefits of intravenous thrombolysis for patients with presumed acute schaemic stroke.MethodsWe performed a systematic review and meta‐analysis of randomised clinical trials of intravenous thrombolysis compared with control in patients with presumed acute ischaemic stroke. The effectiveness of thrombolysis on functional outcome, symptomatic intracranial haemorrhage, early mortality and mortality at final follow up was assessed using a fixed‐effect meta‐analysis.ResultsA total of 26 studies that randomised 10 431 participants were included. The use of thrombolysis was associated with an increased odds of good functional outcome, estimated odds ratio (OR) 1.14 (95% confidence interval [CI] 1.04–1.25, P = 0.004), and also a significantly increased risk of symptomatic intracranial haemorrhage, estimated OR 4.28 (95% CI 3.34–5.48, P < 0.0005) and an increased risk of early mortality, estimated OR 1.51 (95% CI 1.27–1.78, P < 0.0005). There was no statistically significant evidence that the effect of recombinant tissue plasminogen activator (rt‐PA) was different from that of other thrombolytic agents. There was also an increase in mortality at final follow up associated with treatment with thrombolysis, estimated OR 1.17 (95% CI 1.06–1.30, P = 0.003), although this result was not consistent when limited to studies of rt‐PA, estimated OR 1.04 (95% CI 0.92–1.18, P = 0.49).ConclusionsThere is clear evidence of increased early mortality, increased rates of symptomatic intracranial haemorrhage and also of improved functional outcomes for patients with presumed acute ischaemic stroke treated with thrombolysis. The available data are unlikely to resolve the controversy regarding the use of intravenous thrombolysis in this population, and further randomised controlled trials are urgently required.
Nitrogen regulation of the xyl genes of Pseudomonas putida mt‐2 propagates into a significant effect of nitrate on m‐xylene mineralization in soil
Authors: Svenningsen Nanna B. , Nicolaisen Mette H. , Hansen Hans Christian B. , de Lorenzo Victor , Nybroe Ole 
Published: August 2016

SummaryThe nitrogen species available in the growth medium are key factors determining expression of xyl genes for biodegradation of aromatic compounds by Pseudomonas putida. Nitrogen compounds are frequently amended to promote degradation at polluted sites, but it remains unknown how regulation observed in the test tube is propagated into actual catabolism of, e.g. m‐xylene in soil, the natural habitat of this bacterium. To address this issue, we have developed a test‐tube‐to‐soil model system that exposes the end‐effects of remediation practices influencing gene expression of P. putida mt‐2. We found that NO3− compared with NH4+ had a stimulating effect on xyl gene expression in pure culture as well as in soil, and that this stimulation was translated into increased m‐xylene mineralization in soil. Furthermore, expression analysis of the nitrogen‐regulated genes amtB and gdhA allowed us to monitor nitrogen sensing status in both experimental systems. Hence, for nitrogen sources, regulatory patterns that emerge in soil reflect those observed in liquid cultures. The current study shows how distinct regulatory traits can lead to discrete environmental consequences; and it underpins that attempts to improve bioremediation by nitrogen amendment should integrate knowledge on their effects on growth and on catabolic gene regulation under natural conditions.

Published: August 2016

SummaryPoly‐γ‐glutamic acid (γ‐PGA) is a promising microbial polymer with potential applications in industry, agriculture and medicine. The use of high γ‐PGA‐producing strains is an effective approach to improve productivity of γ‐PGA. In this study, we developed a mutant, F3‐178, from Bacillus subtilis GXA‐28 using genome shuffling. The morphological characteristics of F3‐178 and GXA‐28 were not identical. Compared with GXA‐28 (18.4 ± 0.8 g l−1), the yield of γ‐PGA was 1.9‐fold higher in F3‐178 (34.3 ± 1.2 g l−1). Results from batch fermentation in 3.7 l fermenter showed that F3‐178 was satisfactory for industrial production of γ‐PGA. Metabolic studies suggested that the higher γ‐PGA yield in F3‐178 could be attributed to increased intracellular flux and uptake of extracellular glutamate. Real‐time PCR indicated that mRNA level of pgsB in F3‐178 was 18.8‐fold higher than in GXA‐28, suggesting the higher yield might be related to the overexpression of genes involved in γ‐PGA production. This study demonstrated that genome shuffling can be used for rapid improvement of γ‐PGA strains, and the possible mechanism for the improved phenotype was also explored at the metabolic and transcriptional levels.

Published: August 2016

SummaryConsidering wide utilization and high methane fluxes from anaerobic biological stabilization ponds (ABSPs), understanding the methanogenesis in ABSPs is of fundamental importance. Here we investigated the variation and impact factors of methanogenesis in seven ABSPs that spanned from the north to the south of China. Results showed that methanogen abundance (7.7 × 109–8.7 × 1010 copies g−1 dry sediment) and methanogenic activities (2.2–21.2 μmol CH4 g−1 dry sediment h−1) were considerable for all sediments. Statistical analysis demonstrated that compared with other factors (ammonium, pH, COD and TOC), mean annual temperature (MAT) showed the lowest P value and thus was the most important influencing factor for the methanogenic process. Besides, with the increasing MAT, methanogenic activity was enhanced mainly due to the shift of the dominant methanogenic pathway from acetoclastic (49.8–70.7%) in low MAT areas to hydrogenotrophic (42.0–54.6%) in high MAT areas. This shift of methanogenic pathway was also paralleled with changes in composition of bacterial communities. These results suggested that future global warming may reshape the composition of methanogen communities and lead to an increasing methane emission from ABSPs. Therefore, further research is urgently needed to globally estimate methane emissions from ABSPs and re‐examine the role of ABSPs in wastewater treatment.

Published: August 2016

SummaryObjectivesLongitudinal data are limited regarding outcomes and costs beyond 1 year after acute myocardial infarction (MI) among elderly (≥65 years old) US patients. This study examined long‐term outcomes and healthcare costs among elderly MI survivors.MethodsRetrospective analysis of 2002–2009 Medicare healthcare claims (5% random sample). Patients were ≥65 years old and survived ≥1 year without recurrent MI after MI hospitalization. Mortality, incidence of hospitalizations for stroke, major bleeding, MI, a composite endpoint (death, MI, or stroke), and nonpharmacy healthcare costs were determined.ResultsEligible patients included 16 244 STEMI, 34 576 NSTEMI, and 3109 unspecified MI. NSTEMI and unspecified MI patients had significantly higher prevalence of comorbidities than STEMI patients, except for hypertension and dyslipidemia. MI incidence declined 36% over the follow‐up (3.82/100 person‐years [PY] to 2.45/100 PY). Mortality, stroke, and bleeding decreased until the third year of follow‐up and then increased. NSTEMI and unspecified MI patients had a significantly higher incidence of death, MI, the composite, and bleeding than STEMI patients throughout follow‐up. All‐cause inpatient costs during follow‐up were 2.6‐ and 1.9‐fold higher than baseline for STEMI and NSTEMI, respectively; cardiovascular‐related inpatient costs were 3.5‐ and 2.2‐fold higher, respectively.ConclusionsRisks of mortality and cardiovascular events remain high in a Medicare population surviving >1 year after a MI. Continuing healthcare costs are doubled over pre‐MI levels up to 5 years after an MI. Secondary prevention measures beyond the acute post‐MI period may be indicated to reduce risk and cost in this chronic disease phase.
