Published: May 2016

Abstract
In this article, we present an approach based on generalized additive models (GAMs) to predict species’ distributions and abundance in Florida estuaries with habitat suitability modeling. Environmental data gathered by fisheries-independent monitoring in Tampa Bay from 1998 to 2008 were interpolated to create seasonal habitat maps for temperature, salinity, and dissolved oxygen and annual maps for depth and bottom type. We used delta-GAM models assuming either zero-adjusted gamma or beta-inflated-at-zero distributions to predict catch per unit effort (CPUE) from five habitat variables plus gear type for each estuarine species by life stage and season. Bottom type and gear type were treated as categorical predictors with reference parameterization. Three spline-fitting procedures (the penalized B-spline, cubic smoothing spline, and restricted cubic spline) were applied to the continuous predictors. Two additive, linear submodels on the log and logistic scales were used to predict CPUEs &gt;0 and CPUEs = 0, respectively, across environmental gradients. The best overall model among those estimated was identified based on the lowest Akaike information criterion. A stepwise routine was used to omit continuous predictors that had little predictive power. The model developed was then applied to interpolated habitat data to predict CPUEs across the estuary using GIS. The statistical models, coupled with the use of GIS, provide a method for predicting spatial distributions and population numbers of estuarine species’ life stages. An example is presented for juvenile pink shrimp Farfantepenaeus duorarum during the summer in Tampa Bay, Florida.

Do Elementary Students Substitute Ice Cream and Baked Goods for Healthier National School Lunch Program Meal Items?
Authors: Miller Gabrielle F. , Kropp Jaclyn D. , Gupta Sonam , Grogan Kelly A. , Mathews Anne 
Published: May 2016

AbstractWe use variation in à la carte dessert availability to determine its impact on elementary school students’ selection of reimbursable meals and healthful meal components. On days when desserts (ice cream and baked goods) were offered, students were less likely to select a reimbursable meal, and students who purchased a dessert selected fruit significantly less often. Data were collected in the Alachua County School District (Florida) for three weeks in May of 2013. These findings suggest that students substitute desserts for reimbursable meals and the healthier fruit component. Policies, such as Smart Snacks in Schools, that regulate the nutritional content of a la carte items, but do not remove a la carte items from school lunchrooms, may be less effective than intended if such substitution occurs.
Modified Bilateral Neurovascular Cheek Flap: Functional Reconstruction of Extensive Lower Lip Defects
Authors: Chowchuen Bowornsilp 
Published: May 2016

Background:
Reconstruction of extensive lower lip defects is challenging, and functional outcomes are difficult to achieve.

Methods:
A modified bilateral neurovascular cheek (MBNC) flap has been described. The data of patients with cancer of the lower lip treated with wide excision and reconstructed with the MBNC flap in the Plastic Surgery Unit, Srinagarind Hospital, Khon Kaen University, from 1966 to 2012 were reviewed.

Results:
Of the total of 143 patients included, 90.91% were women, and their age ranged from 32 to 100 years. All defects involved 70% or greater of the lower lip, which included oral commissure, buccal mucosa, or cheek skin and upper lip. All 20 patients who were followed up demonstrated good outcomes of intercommissural distance, interlabial distance, sulcus depth, and 2-point discrimination compared with normal lip parameters according to age group and satisfaction with treatment.

Conclusions:
Reconstruction of extensive lower lip defects with the MBNC flap provided good oral competence and functional outcomes. The flap provided adequate lip height and width, with proper position of oral commissure and vermilion reconstruction. The awareness about neurovascular anatomy of the lip and cheek and gentle dissection preserve the lip function. The flap overcomes the drawbacks of Karapandzic technique, which is microstomia, and of Bernard technique, which is a tight adynamic lower lip. It can be used in defects of more than two-thirds of the lip, extending to the cheek, commissural reconstruction, and secondary reconstruction.
Bowel Dysfunction and Self-management for Bowel Symptoms After Sphincter-Preserving Surgery
Authors: Hou Xiao-Ting , Pang Dong , Lu Qian , Yang Ping , Jin San-Li 
Published: May 2016

Background:
After sphincter-preserving surgery (SPS), patients with rectal cancer present multiple bowel symptoms, which significantly affect their daily lives. However, to date, few studies have been conducted in China to identify bowel symptoms and self-management behaviors and to explore the relationship between these behaviors and bowel symptoms.

Objective:
To describe bowel symptoms among Chinese patients with rectal cancer after SPS, the self-management behaviors used, and the relationship between the symptoms and behaviors.

Methods:
A convenience sample of 175 rectal cancer patients who underwent SPS was recruited from 2 tertiary hospitals in Beijing, China, between July and December 2014. The participants completed a general information structural questionnaire, the Chinese version of the Memorial Sloan-Kettering Cancer Center Bowel Function Instrument, and the Bowel Symptoms Self-Management Behaviors Questionnaire.

Results:
The frequencies of 18 bowel symptoms ranged between 16.0% and 96.0%. Diet self-management was the most common behavior and therapy self-management was the least frequent behavior. Although therapy self-management had best effects relatively, other effective behaviors included self-management of the perianal skin and self-management of social activities. The frequency of use of self-management behaviors was significantly positively associated with bowel symptoms (r=−0.232 to −0.580, P < .01).

Conclusions:
Several bowel symptoms after SPS are highly prevalent. Patients with severe bowel symptoms are more likely to use self-management behaviors regularly; however, there is no scientific evidence that these behaviors produce satisfactory results.

Implications for Practice:
Healthcare providers should identify bowel symptoms after SPS and develop supportive interventions for the self-management of symptoms.
Brief Report: HIV-1 Infection Results in Increased Frequency of Active and Inflammatory SlanDCs that Produce High Level of IL-1β
Authors: Tufa Dejene M. , Ahmad Fareed , Chatterjee Debanjana , Ahrenstorf Gerrit , Schmidt Reinhold E. , Jacobs Roland 
Published: May 2016

Abstract:
HIV infection is marked by phenotypic and functional alterations of immune cells. Different studies have shown both numerical and functional deterioration of dendritic cells in HIV-1–infected patients. In this study, we report an increase of inflammatory 6-sulfo LacNAc dendritic cells (slanDCs) that are more activated and produce higher amounts of interleukin (IL)-1β during HIV-1 infection as compared with healthy controls. IL-1β plays a regulatory role in chronic inflammatory disorders. Therefore, our findings might reveal a compensatory regulatory function of slanDCs during HIV-1 infection.
Virtual cortical resection reveals push-pull network control preceding seizure evolution
Authors: Khambhati Ankit N. , Davis Kathryn A. , Lucas Timothy H. , Litt Brian , Bassett Danielle S. 
Published: May 2016

AbstractFor ≈ 20 million people with drug-resistant epilepsy, recurring, spontaneous seizures have a devastating impact on daily life. The efficacy of surgical treatment for controlling seizures is hindered by a poor understanding of how some seizures spread to and synchronize surrounding tissue while others remain focal. To pinpoint network regions that regulate seizure evolution, we present a novel method to assess changes in synchronizability in response to virtually lesioning cortical areas in a validated computational network model. In human patients implanted with electrocorticographic sensors, we apply our virtual cortical resection technique to time-varying functional networks and identify control regions that synchronize or desynchronize cortical areas using an antagonistic push-pull control scheme to raise or lower synchronizability. Our results suggest that synchronizability before seizures predicts seizure evolution: in focal seizures, the strongest controllers are located outside seizure-generating areas. These methods,while applied here to epilepsy, are generalizable to other brain networks, and have wide applicability in isolating and mapping functional drivers of brain dynamics in health and disease.
A survey on lean manufacturing implementation in a selected manufacturing industry in Iran
Authors: Zahraee Seyed Mojib 
Published: May 2016

Purpose
Lean manufacturing (LM) practices and tools are among the key concepts that assist managers and engineers sustain competitiveness in an expanding global market. The purpose of this paper is to identify effective practices and tools of lean manufacturing implementation in an Iranian manufacturing industry.

Design/methodology/approach
This study used a quantitative method. Stratified random sampling and self-administrated questionnaires were sent to respondents in an Iranian manufacturing industry.

Findings
The final results indicate that processes and equipment, planning and control, supplier relationship, human resources and customer relations are significant practices in lean manufacturing in Iranian manufacturing factories. The results from this survey additionally show that lean tools such as Kaizen, 5S, setup time reduction, cellular manufacturing, continuous flow, equipment layout, product design simplicity and error proof equipment are crucial to lean manufacturing implementation.

Research limitations/implications
This study focused solely on a manufacturing industry in Iran that deals with electrical, electronic, metal, plastic, rubber and other automotive components.

Practical implications
The findings of this study emphasize some implications and suggest that reducing cost is more effective and decreased inventory is less effective on lean manufacturing implementation. The current study results should assist quality mangers, product managers and director managers as well as academicians.

Originality/value
An investigation was carried out in this study based on the current situation of Iran’s manufacturing industry to empirically examine and evaluate the effect of lean practices and tools. Besides, a very limited number of studies have been done regarding the implementation of lean thinking and practices in Iran’s manufacturing industry.
Experimental characterization and numerical analysis of the weld-region material in friction stir welded thick AA2139-T8 plates
Authors: Grujicic Mica , Snipes Jennifer , Ramaswami S , Yen Chian-Fong 
Published: May 2016

Purpose
– The weld region obtained during friction stir welding (FSW) of metallic materials (including aluminum alloys) contains typically well-defined zones, each characterized by fairly unique microstructure and properties. The purpose of this paper is to carry out combined experimental and numerical investigations of the mechanical properties of materials residing in different weld zones of FSW joints of thick AA2139-T8 plates.

Design/methodology/approach
– Within the experimental investigation, the following has been conducted: first, optical-microscopy characterization of the transverse sections of the FSW joints, in order to help identify and delineate weld zones; second, micro hardness field generation over the same transverse section in order to reconfirm the location and the extent of various weld zones; third, extraction of miniature tensile specimens from different weld zones and their experimental testing; and finally, extraction of a larger size tensile specimen spanning transversely the FSW weld and its testing. Within the computational investigation, an effort was made to: first, validate the mechanical properties obtained using the miniature tensile specimens; and second, demonstrate the need for the use of the miniature tensile specimens.

Findings
– It is argued that the availability of weld-zone material mechanical properties is critical since: first, these properties are often inferior relative to their base-metal counterparts; second, the width of the weld in thick metallic-armor is often comparable to the armor thickness, and therefore may represent a significant portion of the armor exposed-surface area; and finally, modeling of the weld-material structural response under loading requires the availability of high-fidelity/validated material constitutive models, and the development of such models requires knowledge of the weld-material mechanical properties.

Originality/value
– The importance of determining the mechanical properties of the material in different parts of the weld zone with sufficient accuracy is demonstrated.
Energy efficient and latency optimized media resource allocation
Authors: Nosrati Masoud , Karimi Ronak 
Published: May 2016

Purpose
This paper aims to provide a method for media resource allocation in Cloud systems for supporting green computing policies, as well as attempting to improve the overall performance of system by optimizing the communication latencies.

Design/methodology/approach
A common method for resource allocation is using resource agent that takes the budgets/prices of applicants/resources and creates a probability matrix of allocation according to the policies of system. Two general policies for optimization are latency optimization and green computing. Presented heuristic for latencies is so that the average latencies of communication between applicant and resource are measured, and they will affect the next decision. For gaining green computing, it is attempted to consolidate the allocated resources on smaller number of physical machines. So calculation formula of the price of each resource is modified to decrease the probability of allocating the resources on the machine with least allocated resources.

Findings
Results of proposed method indicates its success in both green computing and improving the performance. Experiments show decreasing 21.4 per cent of response time simultaneously with increasing tasks in the tested range. The maximum and minimum of saved energy is acceptable and reported as 79.2 and 16.8 per cent.

Research limitations/implications
Like other centralized solutions, the proposed method suffers from the limitations of centralized resource agent, like bottle neck. But the implementation of distributed resource agent is postponed to future work.

Originality/value
Proposed method presents heuristics for improving the performance and gaining green computing. The key feature is formulating all the details and considering pitch variables for controlling the policies of system.
User centred design and validation during the development of domestic brain computer interface applications for people with acquired brain injury and therapists: a multi-stakeholder approach
Authors: Daly Lynn Jean Mary , Armstrong Elaine , Martin Suzanne 
Published: May 2016

Purpose
– The purpose of this paper is to outline the application of user centred design (UCD) within a research project to support the design, development and evaluation of a brain computer interface (BCI) with associated home-based services and remote therapy station for people with acquired brain injury (ABI).

Design/methodology/approach
– A multi- stakeholder UCD approach was adopted to include people living with ABI, their caregivers and therapists providing rehabilitation. A three-phased iterative approach was implemented: Phase 1 was to gather user requirements, Phase 2 an iterative design phase with end user (EU) groups and therapists and finally the verification and implementation phase. The final phase had two strands of a home-based BCI evaluation with target EUs and their caregivers, alongside this, therapists evaluated the final therapist station that supports the use of the BCI at home. Ethical governance, inline with Ulster University, was awarded.

Findings
– UCD enabled the co-creation and validation of a home-based BCI system for social inclusion and rehabilitation.

Originality/value
– This was the first BCI project to adopt UCD to design and validation a novel home-based BCI system and migrate this from the lab to home. It highlights the importance of UCD to bridge the gap between the technical developers and those whom the technology is aimed at. This complex design process is essential to increase usability and reduce device abandonment.
CSR in Afghanistan: a global CSR agenda in areas of limited statehood
Authors: Azizi Sameer , Jamali Dima 
Published: May 2016

Purpose– The purpose of this paper is to explain the emergence of CSR in Afghanistan as a novel context in the South-Asian CSR debate.Design/methodology/approach– The findings of the paper are based on case studies of four corporations in the Afghan mobile telecommunications industry. Multiple sources of qualitative data are coded according to the analytical framework of the paper to generate the findings.Findings– The findings highlight that the Afghan national setting can be conceptualised as an “area of limited statehood” indicating the weak national institutional setting, which enables space for manoeuvring for non-state actors to play a pivotal role in business-society relations. The paper highlights that the CSR practices are driven by the multi-level organisational field that through a unique blend of global coercive, mimetic and normative pressures lead to convergence around explicit CSR themes.Research limitations/implications– The findings are based on CSR practices that are explicitly stated and do not include informal and/or implicit business-society practices in such contexts.Originality/value– This paper combines the literature on areas of limited statehood and the neo-institutional theory to explain the emergence of CSR the Afghan mobile telecommunications industry. The paper advocates for a shift from a national setting focus to a multi-level institutional field lens in providing contextualised explanation of the emergence of CSR in developing countries.

Authors: Arif Imtiaz , Aslam Wajeeha , Ali Muhammad 
Published: May 2016

Purpose
– The purpose of this paper is to explore how social need, social influence and convenience affect dependence on smartphones and purchasing behavior among university students in Pakistan’s emerging economy.

Design/methodology/approach
– Survey methods and non-probability purposive sampling were used to collect data from 337 respondents, and structural equation modeling was used to test the hypothesis.

Findings
– Overall the results provided evidence that social need, social influence and convenience significantly affect students’ dependence on their smartphones. A significant relationship also existed between students’ dependence on smartphones and their purchasing behavior.

Originality/value
– The availability of 3G/4G mobile networks and the growth in smartphones’ computing power have meant that this form of mobile technology is in great demand. This study provides an exclusive viewpoint concerning students’ dependence on smartphones and the effect of this on their purchasing behavior, which is a subject that has not been covered previously in the Pakistani context.
Anorexic response to rapamycin does not appear to involve a central mechanism
Authors: Toklu Hale Z. , Bruce Erin B. , Sakarya Yasemin , Carter Christy S. , Morgan Drake , Matheny Michael K. , Kirichenko Nataliya , Scarpace Philip J. , Tümer Nihal 
Published: May 2016

SummaryThe authors have previously demonstrated that a low and intermittent peripheral dose of rapamycin (1 mg/kg three times/week) to rats inhibited mTORC1 signalling, but avoided the hyperlipidemia and diabetes‐like syndrome associated with higher doses of rapamycin. The dosing regimen reduced food intake, body weight, adiposity, serum leptin and triglycerides. mTORC1 signalling was inhibited in both liver and hypothalamus, suggesting some of the actions, in particular the decrease in food intake, may be the results of a central mechanism. To test this hypothesis, rapamycin (30 μg/day for 4 weeks) was infused into 23–25‐month‐old F344xBN rats by intracerebroventricular (icv) mini pumps. Our results demonstrated that central infusion did not alter food intake or body weight, although there was a tendency for a decrease in body weight towards the end of the study. mTORC1 signalling, evidenced by decreased phosphorylation of S6 protein at end of 4 weeks, was not activated in liver, hypothalamus or hindbrain. Fat and lean mass, sum of white adipose tissues, brown adipose tissue, serum glucose, insulin and leptin levels remained unchanged. Thus, these data suggest that the anorexic and body weight responses evident with peripheral rapamycin are not the result of direct central action. The tendency for decreased body weight towards the end of study, suggests that there is either a slow transport of centrally administered rapamycin into the periphery, or that there is delayed action of rapamycin at sites in the brain.
Suitability of the milk of native breeds of cows from low‐input farms for cheese production, including rennet curd texture
Authors: Wolanciuk Anna , Barłowska Joanna , Litwińczuk Zygmunt , Florek Mariusz 
Published: May 2016

The cheesemaking suitability of the milk of native cow breeds [Polish Red (RP) and White‐Backed (BG)] raised on low‐input farms was assessed. The milk of Polish Holstein‐Friesian cows raised in an intensive system constituted the reference group. Chemical composition, pH, rennet coagulation time, fat dispersion and curd texture were determined. The cows on the low‐input farms produced over 40% less milk, but with higher (P ≤ 0.01) fat content, shorter coagulation time by over 2 min and lower (P ≤ 0.05) fat dispersion. The curds from this milk were significantly springier, more cohesive and harder. The best milk indices were obtained for the RP cows.

Published: May 2016

AbstractPurposeTo study ocular morphology and visual function in relation to general growth in moderate‐to‐late preterm (MLP) children.MethodsVisual acuity (VA), refraction, optic disc parameters, biometric values and anthropometric measures were obtained from 50 eight‐year‐old MLP and 43 full‐term children. Macular parameters were examined by optical coherence tomography. Serum insulin‐like growth factor I (IGF‐I) levels were analysed at birth and at assessment and delta IGF‐I was calculated.ResultsTotal macular volume was significantly less in MLP than in controls (both eyes p < 0.01). Macular volume correlated with head circumference (HCF) at assessment [right eye (RE) p = 0.002, r = 0.67; left eyes (LE) p = 0.01, r = 0.54] and refraction (both eyes p < 0.05, r = 0.4) in the MLP children. Furthermore, central retinal thickness correlated significantly with delta IGF‐I (RE p = 0.03, r = −0.51, LE p = 0.006, r = −0.59) and refraction (both eyes p < 0.01, r = 0.5) and optic disc areas correlated with weight and height at assessment (all p < 0.05, r = 0.4). Total axial length correlated with HCF at assessment (both eyes p < 0.01, r = 0.5) and VA logMAR (both eyes p < 0.02, r = −0.4).ConclusionsMacular volume was significantly less in MLP children than in controls examined at 8 years of age. General growth of children and IGF‐I levels seem to be involved in development of ocular growth and morphology.
