Numerical analysis of the effects of changing hydraulic parameters on saltwater intrusion in coastal aquifers
Authors: Abd-Elaty Ismail , Abd Elhamid Hany Farhat , Javadi Akbar 
Published: February 2017

PurposeThe purpose of this paper is to develop and validate a numerical model to study the effect of changing hydraulic parameters on saltwater intrusion in coastal aquifers.Design/methodology/approachThe numerical model SEAWAT is validated and applied to a hypothetical case (Henry problem) and a real case study (Biscayne aquifer, Florida, USA) for different values of hydraulic parameters including; hydraulic conductivity, porosity, dispersion, diffusion, fluid density and solute concentration. The dimensional analysis technique is used to correlate these parameters with the intrusion length.FindingsThe results show that the hydraulic parameters have a clear effect on saltwater intrusion as they increase the intrusion in some cases and decrease it in some other cases. The results indicate that changing hydraulic parameters may be used as a control method to protect coastal aquifers from saltwater intrusion.Practical implicationsThe results of the application of the model to the Biscayne aquifer in Florida showed that the intrusion can be reduced to 50 percent when the hydraulic conductivity is reduced to 50 percent. Decreasing hydraulic conductivity by injecting some relatively cheap materials such as bentonite can help to reduce the intrusion of saltwater. So the saltwater intrusion can be reduced with relatively low cost through changing some hydraulic parameters.Originality/valueA relationship to calculate intrusion length in coastal aquifer is developed and the impact of different hydraulic parameters on saltwater intrusion is highlighted. Control of saltwater intrusion using relatively cheap method is presented.
The relationship between perceived pay equity, productivity, and organizational commitment for US professionals of color
Authors: Buttner E. Holly , Lowe Kevin B. 
Published: February 2017

PurposeThe purpose of this paper is to examine: the direct effect of perceived pay equity, the interaction of perceived pay equity and productivity, and the relative effects of perceived internal and external pay equity on organizational commitment (OC) among US scholars of color.Design/methodology/approachThe study surveyed 160 professionals. Correlation and hierarchical regression were employed to test the hypotheses.FindingsPerceived pay equity directly influenced OC and interacted with scholarly productivity to affect commitment. Highly productive participants who perceived pay equity reported the highest commitment. When pay was seen as inequitable, the most productive scholars reported the lowest commitment. Perceived internal pay equity had an effect, over and above perceived external pay equity on commitment.Research limitations/implicationsThe study was conducted in one industry in the USA, so the results should be generalized cautiously. While, the data were single-source and cross-sectional, the findings were consistent with previous research.Practical implicationsFindings may be useful for minority scholars’ supervisors since they have knowledge of the productivity and salaries in the department and can provide a detailed explanation for pay differences to enhance pay equity perceptions, particularly for the most productive scholars.Originality/valueThis study adds to the equity and relative deprivation theory research investigating the effect of perceived pay equity on employee outcomes by examining perceived internal and external pay equity perceptions and productivity on OC. Results suggest that highly productive minority professionals in higher education are particularly sensitive to pay equity.
An assessment of OECD sustainable portfolios with a multi-criteria approach under uncertainty
Authors: Cortez Alejandro Klender , Rodríguez García Martha del Pilar 
Published: February 2017

PurposeThis paper aims to analyse the differences in financial performance portfolios between sustainable and non-sustainable firms through the use of portfolio theory and OptQuest algorithms from 2007 to 2013.Design/methodology/approachThe sample consists of 1,078 firms from 15 Organisation for Economic Cooperation and Development countries. A maximisation weighted ratio is estimated by applying OptQuest algorithms to measure the portfolio performance considering a fuzzy Jensen’s alpha and the percentage of the portfolio’s performance that exceeds the market.FindingsThe results show a similar financial performance in sustainable portfolios (SP) and non-SP, but considering the uncertainty, the performance in sustainable firms was better than that of non-sustainable ones. Uncertainty was reduced, as it passed the beginning of the crisis from 2008-2009 to 2012-2013.Research limitations/implicationsThe main limitation is the different assessments of sustainability indexes in each of the countries.Practical implicationsThe results help investors assess their decisions in an uncertain economic environment and allocate their investment in not only financial terms but also social character.Social implicationsCountries with higher financial performances in SP show the efficiency in their legal environmental regulations. On the other hand, the degree of uncertainty is lower in the SP than non-SP, suggesting that sustainable firms in financial crisis could be more responsible in social claims such as good working conditions.Originality/valueThis study contributes to existing research in two ways. First, the paper studies corporate social responsibility by different continents and countries in an uncertain economic timespan. For this, the legal, cultural and socioeconomic divergences and convergences were explored. Second, the research presented an analysis of the financial performance differences between sustainable and non-SP by applying a hybrid methodology with fuzzy regression and OptQuest algorithms.
The basis for establishing one or more Europes
Authors: Gil Aluja Jaime 
Published: February 2017

Purpose
This work aims to ask for the possibility to establish one or more Europes in a heterogeneous territory where the main goal is to create a common space. The use of a specific methodology will help us to know whether it is possible to apply general policies in the whole territory or it will be necessary to adapt them to a different group of spaces.

Design/methodology/approach
Taking into account the experts’ opinions, causality relationships, grouping processes and distances techniques can be obtained to get an overall view of different groups of areas where it will be possible to develop the specific policies successfully.

Findings
Theoretically, the proposed model using fuzzy logic in grouping processes presents significant results that contribute to the theory on regional development.

Originality/value
This paper provides a new approach to solve the territorial problem to apply the European policies. Introducing these techniques, one will be able to approach the different positions to the specific areas in Europe to create a peaceful and harmonic space of cohabitation.
Sustainability, blended learning and the undergraduate communication skills classroom: negotiating engineering undergraduates’ expectations and perceptions
Authors: Sivapalan Subarna 
Published: February 2017

Purpose
This paper aims to discuss the outcomes of a study conducted to explore the perceptions and expectations of undergraduate engineering learners on the potential of incorporating sustainability within the Professional Communication Skills (PCS) module, via blended learning.

Design/methodology/approach
A mixed methods case study approach was used, using surveys, learner reflections and interviews.

Findings
Key findings include (a) learners finding a heightened sense of awareness of environmental, social and cultural dimensions of sustainability, (b) development of sustainability literacy and communication skills for the real world, (c) scepticism and apprehension of blended learning teaching and learning methods, (d) development of capacity for self-directed learning resulting from flipped learning and (e) differences in quality of peer and lecturer interaction online and in the traditional classroom set up.

Originality/value
Sivapalan’s (2015) study suggests that Malaysian engineering graduates lack sustainability knowledge, competences and values, and often struggle to cope with professional responsibilities that require them to exercise these literacies. Much of this is attributed to the lack of sustainability integration within the undergraduate engineering curriculum, and within teaching approaches used. To date, there is little research within the Malaysian engineering education context to gauge the extent to which non-technical academic modules such as the PCS module could be used as a platform to incorporate sustainability learning outcomes. Research to gauge learners’ feedback and reflections on the integration of sustainability via non-technical modules and blended learning approaches is also scarce.
Learning for sustainability in the digital world
Authors: Speight Sarah 
Published: February 2017

Purpose
The purpose of this editorial is to provide some context to this special issue and explain how the authors are linking sustainability and digital literacy.

Design/methodology/approach
Making reference to relevant literature, the paper explores how the four case studies, all written by practitioners, adopt particular approaches to learning for sustainability.

Findings
Driven by personal commitment to the sustainability agenda, the authors have found their own routes to developing effective learning for their own students or for general audiences via massive open online courses (MOOCs). Their initiatives have limited reach at present, but all signal the growing commitment within higher education to sustainability as a subject of study and pedagogic approach in teaching and learning, and to the development of digital literacy.

Originality/value
Digital pedagogies can support sustainability literacy by facilitating the convenient delivery of content and also by facilitating networked and collaborative learning that can cross the boundaries of culture and context.
Unseeing Chinatown: Universal Zoning, Planning Abstraction and Space of Difference
Authors: Rugkhapan Napong Tao 
Published: February 2017

AbstractThe article investigates the technical rationality behind Bangkok's recent land use zoning plans. It does so through the example of Chinatown. The plans, intended to promote urban sustainability, introduce zoning techniques such as (1) land use subcategorization to hierarchize urban districts, and (2) density zoning to encourage intensive development around transit stations. The case of Chinatown foregrounds the discussion in this article, which then, in turn, explores the two zoning techniques. I argue that both techniques are formulated through a functionalist rationality, and thus omit place‐specific conditions of land, such as local practices, histories and land tenure. Worse yet, the landed elite uses them to justify displacement and eviction. The article theorizes Chinatown as a space of difference, pointing to particularities that are unseen and thus at risk of being unmade by what is often passed off as technical expertise.
Adapting and Applying the Phenice (1969) Adult Morphological Sex Estimation Technique to Subadults
Authors: Klales Alexandra R. , Burns Tesa L. 
Published: February 2017

AbstractThis research evaluated whether adult morphological sex estimation methods of the innominate could be adapted and applied to subadults. The subpubic concavity, described by Phenice (1969) and revised by Klales et al. (2012), was modified for use with subadults. Two observers scored radiographic images from the PATRICIA database of 334 individuals of both sexes aged between 1.19 and 20.47 years. Score frequencies shifted from score 2 (straight) to higher frequencies of score 3 (convexity) in males and score 1 (concavity) in females with increasing age. Using ordinal logistic regression, sex classification was highest for the oldest age cohort at 97.2% and then decreased by age cohort. Interobserver error rendered a high level of agreement (0.806) using the intraclass correlation coefficient. Results indicate that the Klales method can be modified and applied to subadults to accurately estimate sex following the onset of puberty with a high degree of reliability and validity.
Signs of Fungal Infection in Dead Mimic the Chronic Torture
Authors: Pathak Akhilesh K. , Shukla Vaishaki Y. 
Published: February 2017

AbstractThe cases of battered woman syndrome (BWS) are very common in India. The majority of the women suffer battering by their family members especially in‐laws. The injuries occurring each time indicate their being battered, but on being questioned about these happenings, a mismatched history being given by them is the major indication of BWS. In many of the cases, the injuries present over the body either in healing stages or in association with skin diseases may mislead the forensic pathologists and investigating agencies. One such rare autopsy was conducted where the healing lesions of the chronic fungal infections were mistaken as the injuries of chronic torture. The case is presented here to remind to the forensic pathologist about the possibility of the signs of chronic fungal infections in dead, which can mimic the torture, and to discuss its medicolegal implications.
The Effect of Varying the Composition of Fingerprint Sweat Deposits on the Corrosion of Brass and Fingerprint Visibility
Authors: Cooper‐Dunn Alice , Jones Owen , Bond John W. 
Published: February 2017

AbstractCorrosion of α‐phase brass by sebaceous sweat fingerprint deposits produced identifiable impressions in a majority of samples (n = 40) 4 days after deposition. Combining sebaceous with eccrine sweat yielded a greater percentage of identifiable fingerprint deposits, although this increase was not statistically significant. Production of identifiable fingerprints from eccrine sweat deposits was dependent on the sampling time of year with deposits taken during summer months giving similar percentages of identifiable fingerprints to sebaceous deposits. A statistically significant positive correlation was found between elapsed days after deposition and identifiable eccrine (ρ = 0.787, p < 0.05), sebaceous (ρ = 0.724, p < 0.05), and eccrine/sebaceous mixture (ρ = 0.908, p < 0.01) fingerprints deposited during summer months. The summer increase in the percentage of identifiable eccrine sweat deposits was statistically significant compared to winter eccrine deposits (p < 0.0001). Observations were consistent with results obtained from artificial sebaceous and eccrine sweat.
Alteration of the Death Scene After Self‐stabbing: A Case of Sharp Force Suicide Disguised by the Victim as a Homicide?
Authors: Pelletti Guido , Visentin Sindi , Rago Claudio , Cecchetto Giovanni , Montisci Massimo 
Published: February 2017

AbstractThis paper reports a case of a 72‐year‐old woman who was found dead in her bedroom with a 4 cm vertical stab wound in the abdomen. A bloodstained knife was found in the top drawer of her bedside table. The clothes worn by the victim showed no damage. A bloodstained vest and a sweater with frontal incisions were found far from the victim, in the bathroom and in the bedroom respectively. Several bloodstains were found in every room of the apartment. The evidence found during the forensic examination and, in particular, the Bloodstain Pattern Analysis, led the investigators to determine the manner of death, being consistent with a suicide with a long‐lasting physical activity after self‐stabbing. This report describes an unusual case of “disguised suicide,” in which the victim tried to cover‐up the suicide by changing her clothes and concealing the weapon, in the last minutes of her life.
Review of axillary lesions, emphasising some distinctive imaging and pathology findings
Authors: Gupta Amber , Metcalf Cecily , Taylor Donna 
Published: February 2017

SummaryThe axilla is often included on mammography, ultrasound (US), CT and MRI. Axillary masses can arise from any of the tissue components present in this region including breast parenchyma. Aetiologies include: lymphadenopathy due to inflammation, malignancy and degenerative causes; soft tissue tumours such as haemangioma, lymphangioma, peripheral nerve sheath tumours and lipomas; post‐surgical complications such as seroma, lymphocoele and haematoma; lesions arising in accessory breast tissue such as fibroadenoma and carcinoma. Some of these entities have distinctive imaging appearances knowledge of which can be helpful in suggesting the correct diagnosis.
Transcaval core biopsy in malignant superior vena cava obstruction: Potential for single stage diagnosis and treatment
Authors: Maingard Julian , Brooks Mark 
Published: February 2017

SummarySuperior vena cava syndrome (SVCS) is secondary to obstruction of venous flow from the superior vena cava to the right atrium. Endovascular stenting is particularly useful when severe or rapidly progressive disease requires urgent treatment. In suspected mediastinal malignancy, transcaval biopsy can be combined with endovenous stenting to provide diagnosis and treatment in a single procedure. Three patients were referred for investigation and treatment of SVCS over a 20 month period. Under fluoroscopic guidance Cook Medical transjugular biopsy sets (with 20‐gauge QuickCore biopsy needles) were used and two or three core biopsy samples were obtained. Stents were utilised to treat SVC obstructions in two of three patients. Obtained samples were adequate for histological diagnosis. Diagnoses included small cell and small cell neuroendocrine carcinoma of the lung. No procedural complications were encountered. Importantly, no further invasive diagnostic procedures were required. This is a safe and effective alternative to obtain a histological diagnosis in malignant SVCS and in the appropriate clinical setting biopsy can be combined with SVC stenting in a single procedure.
Risk factors in the development of behaviour difficulties among students with special educational needs and disabilities: A multilevel analysis
Authors: Oldfield Jeremy , Humphrey Neil , Hebron Judith 
Published: February 2017

BackgroundStudents with special educational needs and disabilities (SEND) are more likely to exhibit behaviour difficulties than their typically developing peers.AimThe aim of this study was to identify specific risk factors that influence variability in behaviour difficulties among individuals with SEND.SampleThe study sample comprised 4,228 students with SEND, aged 5–15, drawn from 305 primary and secondary schools across England.MethodExplanatory variables were measured at the individual and school levels at baseline, along with a teacher‐reported measure of behaviour difficulties (assessed at baseline and at 18‐month follow‐up).ResultsHierarchical linear modelling of data revealed that differences between schools accounted for between 13% (secondary) and 15.4% (primary) of the total variance in the development of students’ behaviour difficulties, with the remainder attributable to individual differences. Statistically significant risk markers for these problems across both phases of education were being male, eligibility for free school meals, being identified as a bully, and lower academic achievement. Additional risk markers specific to each phase of education at the individual and school levels are also acknowledged.ConclusionBehaviour difficulties are affected by risks across multiple ecological levels. Addressing any one of these potential influences is therefore likely to contribute to the reduction in the problems displayed.
Progenitor genotyping reveals a complex clonal architecture in a subset of CALR‐mutated myeloproliferative neoplasms
Authors: Martin Sarah , Wright Casey M. , Scott Linda M. 
Published: February 2017

SummaryThe identification of acquired CALR mutations in patients with essential thrombocythaemia (ET) or myelofibrosis (MF) has meant that disease‐initiating mutations can now be detected in about 90% of all patients with a myeloproliferative neoplasm (MPN). Here, we show that only those CALR mutations that cause a +1 frameshift, thereby altering the carboxy‐terminus of calreticulin, promote cytokine independence in vitro; in‐frame deletions were not functional, and are unlikely to be the pathogenetic mutation underlying some MPN cases. Expression of the thrombopoietin receptor, MPL, was also necessary for factor‐independence. Although the CALR mutations are considered to occur only in JAK2 V617F‐negative cases and in a heterozygous state, progenitor genotyping revealed that this is not always true. Notably, CALR mutation‐positive MPNs can be polyclonal: in one case, two distinct CALR mutation‐positive subpopulations could be identified; in another, separate populations of JAK2 V617F‐positive and CALR‐mutated cells were present. Mitotic recombination involving chromosome 19 in a third instance resulted in the emergence of a CALR mutation‐homozygous subclone. Collectively, our studies demonstrate that occasional patients with CALR mutation‐positive ET or MF carry other MPN‐initiating genetic mutations (including JAK2 V617F), acquire “secondary mutations” before or after the CALR mutation, or evolve over time to being CALR mutation‐homozygous.

Published: February 2017

SummaryThe combination of bendamustine, bortezomib and dexamethasone (BBD) was evaluated as a first‐line therapy for multiple myeloma. The original treatment regimen of bendamustine 80 mg/m2, days 1, 4; bortezomib 1·3 mg/m2, days 1, 4, 8, 11; dexamethasone 40 mg, days 1, 2, 3, 4 on a 28‐day cycle (up to 8 cycles) was efficacious but determined relatively toxic in an interim analysis. The regimen was amended to bendamustine 80 mg/m2, days 1, 2; bortezomib 1·3 mg/m2, days 1, 8, 15; dexamethasone 20 mg, days 1, 2, 8, 9, 15, 16 every 28 days (up to 8 cycles), then maintenance 1·3 mg/m2 IV bortezomib every 2 weeks. Fifty‐nine patients were enrolled. Primary endpoint was complete response (CR) rate. The original schema was given for a median of 7 cycles (range 1–8); modified schema was given for a median of 8 cycles (range 1‐8) plus maintenance. Overall response was 91%, CR was 9%. Median follow‐up was 19·1 months; median progression‐free survival was 11·1 months and 18·9 months on the original and modified regimens, respectively. The most common Grade 3/4 adverse events were fatigue and neuropathy. The combination of BBD is tolerable and efficacious in this patient population. Modifications to decrease intensity but increase duration translated to better outcomes.

Published: February 2017

Assembly of cucurbitacin inspired estrone analogs has been previously synthesized and screened against melanoma cell lines. Further synthetic optimization was executed via installation of Azide polar functional moiety across 23, 24 α, β‐unsaturated ketone side chain using Michael addition reaction. This was followed by biological screening against melanoma cell lines employing MTT assay, in‐cell‐based ELISA assay, and Western blot analysis to monitor the potential of the synthesized analogs to inhibit the phosphorylated ERK levels. This resulted in evolution of MH‐4 possessing IC50 of 3.59 μm with significant decrease in the p‐ERK and targeting MAPK pathway.
