Interactions due to hall current and rotation in a magneto-micropolar fractional order thermoelastic half-space subjected to ramp-type heating
Authors: Kumar Rajneesh , Singh Kulwinder , Pathania Devinder 
Published: May 2016

Purpose
– The purpose of this paper is to investigate a two dimensional problem in magneto-micropolar thermoelastic half-space with fractional order derivative in the presence of combined effects of hall current and rotation subjected to ramp-type heating.

Design/methodology/approach
– The fractional order theory of thermoelasticity with one relaxation time derived by Sherief et al. (2010) has been used to investigate the problem. Laplace and Fourier transform technique has been used to solve the resulting non-dimensional coupled field equations to obtain displacement, stress components and temperature distribution. A numerical inversion technique has been applied to obtain the solution in the physical domain.

Findings
– Numerical computed results of all the considered variables have been shown graphically to depict the combined effect of hall current and rotation. Some particular cases of interest are also deduced from the present study.

Originality/value
– Comparison are made in the presence and absence of hall current and rotation in a magneto-micropolar thermoelastic solid with fractional order derivative.
Macroscopic fracture behavior of nickel foam under tension
Authors: Yang Q.C. , Zhang M.J. , Liu P. S. 
Published: May 2016

Purpose
– The samples of nickel foam with porosity of about 88 percent were uniaxially tensioned at room temperature, and the phenomena of tensile fracture were compared with that from the fully dense plate of metal nickel. The purpose of this paper is to investigate the differences between their behaviors of tensile fracture.

Design/methodology/approach
– The tensile test was carried out by using the tester of CMT-series microcomputer-controlled electronic universal testing machine. The difference of tensile fracture behavior between the nickel foam and the dense metal nickel was discussed by analyzing the load-displacement curve and the microscopical fracture.

Findings
– The results indicated that, nickel foam also displayed the feature of macroscopic plastic-deformation during tension, but it showed a macroscopic brittleness much more than that of the fully dense body. The axial apparent strain at the maximum load for the foamed sample was markedly less than that for the dense one. In addition, an obviously gradual course exhibited for the foamed body during tensile failure and a rapidly instant course for the dense body correspondingly.

Originality/value
– There have been some studies on the tensile behavior for metal foams, but much less than on the compression, and the relevant works are mostly for aluminum foam. The present work provides the investigations on the difference of tensile fracture behavior between the nickel foam and the dense metal nickel, as well as that of the corresponding samples in various cases with different tensile velocities. It is found that the porosity can make a remarkable decrease of the apparent strain at the maximum load and a significant increase of the macroscopical brittleness for the metallic nickel under tension.
Jefferson County Alabama: a dark cloud looms
Authors: Guess Aundrea Kay , Broom Lowell , Reburn James 
Published: May 2016

Synopsis
Jefferson County was in a financial crisis as the commissioners faced a decision concerning whether the County should file for bankruptcy. The County was under an EPA mandate to update an outdated and overrunning sewer system. Estimates to do the work ranged from $250 million to $1.2 billion. The situation led to graft, corruption, bribery and illegal activities. More than 20 people were prosecuted in association with the illegal activities involved in financing and construction of the sewer system and four of the five commissioners were sentenced for their involvement in the corruption. Five new commissioners were elected and had to determine what to do after the down-grade of the County's bonds and warrants; the reduced revenues; and the corruption had put the County in a situation where funds were not available to continue to operate the County and provide services to its citizens. Should they declare bankruptcy or choose other paths open to them?

Research methodology
Data sources – this case is based on field research and interviews with a commissioner, court documents and from many other public sources. Extent of disguise – the case is not disguised.

Relevant courses and levels
The case can be used in graduate or upper division undergraduate courses in accounting, strategy, public administration or finance. There are several topics in the case that could be addressed: governance; economics, government and political issues, ethics, accounting, financial instruments, and strategy.

Published: May 2016

Synopsis
The Neenan Company is a construction firm based in Fort Collins, Colorado, known for their efforts in pioneering the advancement of the design/build approach to construction. With a history of industry leadership, innovative contracting methods, and ethical business practices, the company now faces management, customer relations, and financial challenges. Serious structural problems were discovered in a number of public schools and other buildings built by the company. Thrown into a whirlwind of shock, Randy Myers, President of the company, must consider how to respond to the crisis, and how to prevent these issues in the future. Written from his perspective, this case provides a platform for considering the challenges that can result from industry innovation, ethical decision-making, and crisis management.

Research methodology
For the development of this case, the authors interviewed the top management at the Neenan Company: Founder David Neenan, President Randy Myers, and Donna Smith, Vice President of Business Development. The authors also interviewed current employees, previous employees of Neenan, representatives of school buildings built by Neenan, stakeholders, other experts in the construction field and existing customers of the company. The company made internal documents available to the authors, including financial statements and quality control and assessment tools, which were provided by Ryan Dellos, Chief Financial Officer. The authors surveyed financial documents and business documents to analyze pertinent information and data relevant to the case. All the interviews were recorded, coded, and analyzed to include multiple perspectives. Extensive online research was conducted on the construction industry and The Neenan Company which included several news articles and interviews on David and Randy. Additionally, the authors carefully studied the news reports by The Denver Post and other related press materials. Experts from the construction field and financial field provided assistance with data analysis and interpretation. The authors used a variety of academic resources to draw connections between the issues faced by Neenan and concepts discussed in business courses.

Relevant courses and levels
This case has applications in entrepreneurship, small business management, business ethics, leadership, organizational structure/design, and new venture management courses at both undergraduate and graduate levels. It also contains critical areas of decision-making relevant to an advanced strategic management course. The case can be introduced at any stage of the term, and is specifically relevant to discussions focussing on innovation and growth, corporate social responsibility, ethical decision-making, stakeholder theory, entrepreneurial crisis management, and long-term venture success.

Predator refuges for conservation biological control in an intermediately disturbed system: the rise and fall of a simple solution
Authors: Liman Anna‐Sara , Eklund Karin , Björkman Christer 
Published: May 2016

Summary

Managed systems harvested at intermediate time‐scales have advantages over annual short‐cycled systems in maintaining top‐down control of insect herbivores, and the flexible harvest regimes in these systems provide opportunities for habitat management that can stabilize predator–prey population dynamics across harvests – resulting in reduced risk of pest outbreaks.

In a large‐scale field experiment, we explored whether retaining refuges, that is preserving parts of the stand to reduce predator mortality, could reduce the risk of pest insect outbreaks in willow short‐rotation coppice. Population densities of three omnivorous predator species and three outbreaking herbivorous leaf beetle species were monitored over four years after coppice (stem harvest) in eight stands with refuges (treatment) and eight stands without refuges (control). Predation pressure was estimated in years three and four.

Contrary to our predictions, leaf beetle densities were higher in stands with refuges and predator densities were higher in stands without refuges. Leaf beetle egg mortality increased with total predator density, but did not differ between stands with and without refuges.

These unexpected results can be attributed to interactions between dispersal and patch age. The altered phenology of coppiced stems may have triggered leaf beetle aggregation in refuges and migration from stands without refuges. A behavioural response to resource concentration in retained old patches likely transformed the predator refuge from a ‘source’ to a ‘sink’.

Synthesis and applications. This study shows that retaining refuges in willow short‐rotation coppice to facilitate predator population recovery after harvest can come at the cost of more attractive herbivore habitats – and thus increased pest problems. We conclude that crop refuges in systems with intermediate disturbance regimes pose new challenges for conservation biological control, in particular the need to consider how patch age affects dispersal and recolonization of both pest and predators.
Sliding doors in Brussels: A career path analysis of EU affairs managers
Authors: COEN DAVID , VANNONI MATIA 
Published: May 2016

AbstractThis article investigates the revolving doors phenomenon in the European Union (EU). It proposes a management approach that treats this phenomenon as a form of corporate political activity through which companies try to gain access to decision makers. By using sequence analysis to examine the career paths of almost 300 EU affairs managers based in public and private companies across 26 countries, three different ideal‐typical managers are identified: those EU affairs managers coming from EU institutions and public affairs; those who make a career through the private sector; and those who establish themselves in national political institutions. This identification confirms that EU institutions need different types of information and companies need EU affairs managers with different professional backgrounds able to provide it. Rather than observing a revolving door of EU officials into EU government affairs, what the authors term ‘sliding doors’ – namely the separation of careers, especially between the public and private sectors – is discerned.

ObjectiveIn the light of the high prevalence of physical comorbidities in people with psychotic illness, there is a need to explore modifiable risk factors that may contribute to this disease burden. The benefits of physical activity to both physical and mental health have been well established. We aimed to examine the prevalence and correlates of physical activity in a national sample of adults living with psychotic illness.MethodsPhysical activity was assessed in 1801 people using the International Physical Activity Questionnaire. Participants were dichotomised into low and moderate–high physical activity groups and associations between physical activity and a range of sociodemographic, clinical and physical comorbidity variables were examined using logistic regression.ResultsMore than half the participants were categorised in the moderate–high physical activity group with nearly half of the sample engaged in physical activity every day. There were significant associations between low physical activity and older age, unemployment, educational non‐participation, antipsychotic medication use, social dysfunction, self‐reported loneliness and obesity. However, there was no significant association between physical activity and sex, psychosis type, illness duration, physical comorbidity or negative symptoms.ConclusionThe findings from this study may inform future interventions designed to increase physical activity in people with psychotic illness.
Uterine leiomyosarcoma – incidence, treatment, and the impact of morcellation. A nationwide cohort study
Authors: Skorstad Mette , Kent Andrew , Lieng Marit 
Published: May 2016

AbstractIntroductionThe risk of morcellation of occult uterine leiomyosarcomas (LMS) during laparoscopic procedures has been under scrutiny over recent years. The objective of this study was to assess the operative treatment performed in women with uterine LMS in Norway in 2000–2012, including the number of morcellated LMS.Material and methodsRetrospective nationwide cohort study. The study participants were all women with histopathologically verified uterine LMS in Norway during 2000–2012. The data were collected from the Cancer Registry of Norway, National Patient Registry and medical records.ResultsThere were 212 women diagnosed with uterine LMS in Norway in 2000–2012. Mean age at time of diagnosis was 58.1 years (SD ± 12.5). The most frequent symptom in women suffering from LMS was abnormal uterine bleeding [110/212 (51.9%)]. LMS was histopathologically verified in 49/212 (23.1%) preoperatively. In 48/212 (22.6%), a malignant condition was suspected and they were treated accordingly. In 115/212 (54.2%), malignancy was not suspected at time of surgery and the women were treated according to the treatment protocol for fibroids. In only four patients was tissue retrieval by power morcellation conducted, accounting for 1.9% of all LMS cases.ConclusionsIn more than 50% of women suffering from LMS, a malignant diagnosis was not confirmed or suspected prior to surgery. In our material, power morcellation of LMS has not lead to reduced survival. We suggest that power morcellators may be used in surgical treatment of selected cases of premenopausal women with symptomatic, presumed benign uterine leiomyomas.

Published: May 2016

AbstractAn increasing number of suicide attempts involve the ingestion of glyphosate surfactant; hence, clinical toxicologists may encounter severe cases of glyphosate surfactant intoxication. In several other clinical conditions, serum lactate is used to predict outcome. We investigated the relationship between lactate levels and 30‐day mortality from glyphosate surfactant poisoning. This retrospective analysis involved 232 patients who were admitted to the emergency department after acute glyphosate surfactant poisoning between January 2004 and June 2014. We used a receiver operating characteristic (ROC) curve to define the optimal cut‐off point for lactate levels. A Kaplan–Meier 30‐day survival curve was then analysed in terms of the defined cut‐off level. We used multi‐variate Cox proportional hazards regression analysis to determine the risk factors for 30‐day mortality. Of the 232 patients, 29 died, yielding a case fatality rate of 12.5%. Lactate was significantly higher in non‐survivors (6.5 ± 3.1 mmol/L) than in survivors (3.3 ± 2.2 mmol/L; p < 0.001), and elevated lactate was significantly associated with 30‐day mortality. The area under the ROC curve of lactate levels was 0.836 [95% confidence interval (CI): 0.716–0.869]. Lactate levels higher than 4.7 mmol/L were associated with increased mortality in multi‐variable analysis (hazard ratio: 3.2; 95% CI: 1.1–8.7). Besides lactate, age >59 years, corrected QT interval >495 ms and potassium >5.5 mmol/L were independent risk factors for 30‐day mortality. Lactate is an independent predictor of 30‐day mortality in patients with glyphosate surfactant poisoning. Early measurement of lactate levels may be a simple and practical way to assess the severity of intoxication.
On the Combination of c- and D-Optimal Designs: General Approaches and Applications in Dose–Response Studies
Authors: Holland-Letz Tim 
Published: May 2016

Summary
Dose–response modeling in areas such as toxicology is often conducted using a parametric approach. While estimation of parameters is usually one of the goals, often the main aim of the study is the estimation of quantities derived from the parameters, such as the ED50 dose. From the view of statistical optimal design theory such an objective corresponds to a c-optimal design criterion. Unfortunately, c-optimal designs often create practical problems, and furthermore commonly do not allow actual estimation of the parameters. It is therefore useful to consider alternative designs which show good c-performance, while still being applicable in practice and allowing reasonably good general parameter estimation. In effect, using optimal design terminology this means that a reasonable performance regarding the D-criterion is expected as well. In this article, we propose several approaches to the task of combining c- and D-efficient designs, such as using mixed information functions or setting minimum requirements regarding either c- or D-efficiency, and show how to algorithmically determine optimal designs in each case. We apply all approaches to a standard situation from toxicology, and obtain a much better balance between c- and D-performance. Next, we investigate how to adapt the designs to different parameter values. Finally, we show that the methodology used here is not just limited to the combination of c- and D-designs, but can also be used to handle more general constraint situations such as limits on the cost of an experiment.

AbstractAlthough melphalan at a dose of 140 mg/m2 (MEL140) is an acceptable conditioning regimen for autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients, very few studies compared it to the most commonly used dose of 200 mg/m2 (MEL200). A retrospective review of records of MM patients (2001–2010) identified 33 patients who received MEL140 and 96 patients who received MEL200. As expected, significantly higher percentage of patients in the MEL140 arm were >65 years or had cardiac ejection fraction <50%, had Karnofsky score <80, or had creatinine >2 at the time of ASCT (P≤.01). There were no significant differences in incidence of treatment related mortality and morbidity. At a median follow‐up of 74 months from ASCT, there were no significant differences in relapse free survival (RFS) and overall survival (OS) between the two groups. Similar proportion had myeloma status improve to ≥VGPR at 3 months post‐ASCT. Usage of post‐ASCT maintenance was similar. In multivariate cox proportional hazards model, only disease status of ≥VGPR at the time of ASCT significantly improved RFS (P=.024), but not OS (P=.104). In conclusion, MM patients who received MEL140 had similar long‐term outcomes to MEL200 patients despite their older age and co‐morbidities.
