Luxury implications of showcasing a product with its “cast” shadow
Authors: Sharma Nazuk 
Published: November 2016

Purpose
This paper aims to investigate the role of showcasing a product with its cast shadow (formed in the ad’s background by the advertised product) on consumer product perceptions.

Design/methodology/approach
Three experimentally designed studies, incorporating two product categories, demonstrate the impact of visual presentation of a product with its shadow on consumer evaluations. A total of 203 participants (MTurkers, and student respondents at a southern university) provided data for these studies through questionnaires (online as well as paper-pencil formats).

Findings
Findings reveal that the presence of a product’s cast shadow in the ad frame increases its visual acuity, which in turn enhances its luxury perceptions. Downstream, a product shadow’s presence positively impacts its overall evaluations, through enhanced product luxury perceptions. Also, consumers with high Centrality of Visual Product Aesthetics (CVPA) demonstrate a stronger liking for such product presentations.

Research limitations/implications
The current findings not only demonstrate the positive impact of product shadows on consumer perceptions, but also enrich the luxury and aesthetics literature streams.

Practical implications
Advertisers often subjectively use product shadows as stylistic tools in marketing communications. This research offers some practical guidelines to use shadows in fostering product luxury perceptions and better target aesthetically-sensitive consumers.

Originality/value
Advertising research suggests that visual styling and presentation of products significantly impacts consumer perceptions. However, the role of product shadows has not yet been empirically examined. This paper makes an attempt to test whether and how product shadows impact consumer perceptions.
Grocery shopping, a one man job? Understanding the single shopper
Authors: Tariq Ayesha , D’Souza Giles , Allaway Arthur W. 
Published: November 2016

Purpose
Single males and females are an under-studied segment of grocery shoppers. This study aims to compare the shopping habits of single males with single females and couples.

Design/methodology/approach
Structural equation modeling is used to analyze purchase history data for testing the effect of household type on shopping trip metrics and budget allocation to product categories.

Findings
Although single male shoppers differ on some trip metrics from females, differences are more pronounced between single shoppers, male or female, and couples. The study also confirms the mediating effect of trip metrics on the relationship between demographics and allocation of budget to grocery product categories.

Originality/value
The study contributes to the literature by identifying the differences and similarities between shopping behaviors of single males, single females and couples, developing an understanding of their budget allocation decisions to different product categories and testing and confirming that trip characteristics mediate the relationship between demographics and budget allocated to grocery products.
Strategic project management as an innovative approach for sustainable green campus buildings in Africa
Authors: Rwelamila Pantaleo Mutajwaa Daniel , Purushottam Neha 
Published: November 2016

Purpose
Across the African continent many colleges and universities are facing hurdles in sustaining green building initiatives. Often the barriers to green building are not purely financial, they include a significant number of non-financial issues directly connected with the way green building initiatives are integrated within the management of these higher learning institutions (HLIs). The purpose of this paper is to explore the reasons behind widespread barriers and the ways in which the barriers could be overcome through strategic project management.

Design/methodology/approach
The paper includes a critical review of existing literature on barriers to sustaining green building initiatives and an argument is built on the need to manage these initiatives as projects. Consequently it establishes that there is a seamless connection between HLIs strategies and projects, hence strategic project management as a framework to sustain the green campus culture.

Findings
Despite numerous barriers facing African HLIs in embracing green campus buildings (GCBs) as part of their permanent business undertakings; this review strongly suggest a change of direction from “traditional approaches” to strategic project management, where all green building initiatives are transformed to programmes and portfolios dealing with sub-sets of the core business of HLIs.

Practical implications
Strategic decision to include green campus building initiatives (GCBIs) as part of HLIs core strategic business projects will bring permanence in GCB thinking and resources will be allocated to GCBIs and green campus thinking may become a norm and one of the metrics for organization success.

Social implications
Strategic project as a way to creating a conducive-environment for GCBIs success will become a constant and part of the way in which African HLIs are managed.

Originality/value
Contemporary management approaches like strategic project management is embraced as mean for allowing under-resourced African HLIs achieving significant reduction in greenhouse gas emissions.
Effects of Media Channel, Crisis Type and Demographics on Audience Intent to Follow Instructing Information During Crisis
Authors: Park Sejin , Avery Elizabeth Johnson 
Published: November 2016

Media channel use during crisis is an underdeveloped area of crisis communication research. A thorough understanding of how and where people seek information during a crisis is central to effective crisis message strategy, and understanding how the media source of crisis information affects motivation to comply with crisis directives to audiences can further inform crisis management. A survey (N = 454) examines how audiences use media during crisis communication and reveals that (1) people use different media for information seeking during different types of crisis, (2) among demographics, age predicts preferences in information channels during crisis and (3) crisis type and age shape the relationship between media choice and intent to follow recommended behaviours. Theoretical and practical implications of the findings are discussed.
Institutions, governmental performance and the rise of political newcomers
Authors: CARRERAS MIGUEL 
Published: November 2016

AbstractThis article analyses the institutional and contextual factors that facilitate the election of political newcomers as heads of government in democratic regimes. Using data from 870 democratic elections between 1945 and 2015, it is found that political newcomers are more likely to be successful in presidential systems, in new democracies and when party systems are weakly institutionalised. The election of politically inexperienced candidates is also related to governmental performance. Political newcomers are more successful when the economic performance of the government is bad and when the government engages in high‐level corruption.
Exploring subjectivity in competency‐based assessment judgements of assessors
Authors: Bacon Rachel , Holmes Kay , Palermo Claire 
Published: November 2016

AimThe aim of this research was to measure variations in assessors’ judgements of a student dietitian's performance and to explore the influence of group discussion on their judgements.MethodsThe assessments of a student's performance, as observed from a video recording of an authentic nutrition consultation, were measured pre‐ and post‐group discussion by 26 experienced assessors using a mixed‐methods questionnaire. The instrument included a validated 7‐point visual analogue scale (VAS) rating (1 = novice; 7 = competent), a qualitative global description of performance and an assessor's confidence rating (1 = not at all confident; 10 = extremely confident). Scales were analysed descriptively and qualitative responses coded for key themes.ResultsNo agreement was found in assessors’ rating in either the pretest (median = 4, range = 5) or post‐test (median = 4, range = 4); however, the discussion led 78% of participants (20/26) to change their VAS ratings (9/26) and/or confidence levels (16/26). Three themes emerged from the thematic analysis of the participants’ global descriptions of performance: (i) discourse supports assessors to justify their judgements, identify assumptions and learn from the observations of others; (ii) discourse leads assessors to more holistic judgements; and (iii) multiple sources of evidence and student reflections are necessary for credible judgement.ConclusionsThis research questions the notion that ‘actual’ performance can be objectively measured and, rather, considers assessments as ‘interpretations’. This research calls for an integrated interpretivist student‐centred approach to competency‐based assessment.

AbstractZein fibers were successfully fabricated via solution blow spinning (SBS) using acetic acid as solvent. Surface tension, viscosity and modulus of zein solutions were respectively determined by force tensiometer and rheometer. Increases of these properties were observed with an increase of concentration from 20% to 35% (w/w). The fabrication conditions of zein fibers were initially investigated as a function of zein concentration (25% to 35% w/w), feed rate (0.04 to 0.1 mL/min) and air pressure (0.28 to 0.62 MPa). The average fiber diameter (AFD) ranged from 174 to 9595 nm based on scanning electron microscopy (SEM). A Box–Behnken experimental design (BBD) was further performed to identify and quantify the significance of above parameters. The statistical analysis showed that the linear coefficient of concentration, the quadratic term of concentration as well as the interaction between concentration and air pressure were demonstrated statistically significant. Optimal conditions, with an AFD of 138 nm, could be obtained in the SBS of zein fibers by combining a concentration of 23% (w/w), a feed rate of 0.04 mL/min and an air pressure of 0.38 MPa. The moisture sorption capacity of fibers increased slightly as AFD decreased from ∼550 to ∼200 nm, with an increase of BET surface area from 116.5 to 140.0 m2/g.

AbstractIntroductionThis study aimed to evaluate the current use of imaging technologies for planning and delivery of radiotherapy (RT) in Australia.MethodsAn online survey was emailed to all Australian RT centres in August 2015. The survey inquired about imaging practices during planning and treatment delivery processes. Participants were asked about the types of image‐guided RT (IGRT) technologies and the disease sites they were used for, reasons for implementation, frequency of imaging and future plans for IGRT use in their department.ResultsThe survey was completed by 71% of Australian RT centres. All respondents had access to computed tomography (CT) simulators and regularly co‐registered the following scans to the RT: diagnostic CT (50%), diagnostic magnetic resonance imaging (MRI) (95%), planning MRI (34%), planning positron emission tomography (PET) (26%) and diagnostic PET (97%) to aid in tumour delineation. The main reason for in‐room IGRT implementation was the use of highly conformal techniques, while the most common reason for under‐utilisation was lack of equipment capability. The most commonly used IGRT modalities were kilovoltage (kV) cone‐beam CT (CBCT) (97%), kV electronic portal image (EPI) (89%) and megavoltage (MV) EPI (75%). Overall, participants planned to increase IGRT use in planning (33%) and treatment delivery (36%).ConclusionsIGRT is widely used among Australian RT centres. On the basis of future plans of respondents, the installation of new imaging modalities is expected to increase for both planning and treatment.
Informed Preferences? The Impact of Unions on Workers' Policy Views
Authors: Kim Sung Eun , Margalit Yotam 
Published: November 2016

AbstractDespite declining memberships, labor unions still represent large shares of electorates worldwide. Yet their political clout remains contested. To what extent, and in what way, do unions shape workers' political preferences? We address these questions by combining unique survey data of American workers and a set of inferential strategies that exploit two sources of variation: the legal choice that workers face in joining or opting out of unions and the over‐time reversal of a union's policy position. Focusing on the issue of trade, we offer evidence that unions influence their members' policy preferences in a significant and theoretically predictable manner. In contrast, we find that self‐selection into membership accounts at most for a quarter of the observed “union effect.” The study illuminates the impact of unions in cohering workers' voice and provides insight on the role of information provision in shaping how citizens form policy preferences.

AimThe aim was to investigate the ability of a battery of pain models to detect analgesic properties of commonly used analgesics in healthy subjects.MethodsThe battery consisted of tests eliciting electrical, mechanical and thermal (contact heat and cold pressor)‐pain and included a UVB model, the thermal grill illusion and a paradigm of conditioned pain modulation. Subjects were administered fentanyl 3 μg kg–1, phenytoin 300 mg, (S)‐ketamine 10 mg and placebo (part I), or imipramine 100 mg, pregabalin 300 mg, ibuprofen 600 mg and placebo (part II). Pain measurements were performed at baseline and up to 10 h post‐dose. Endpoints were analysed using a mixed model analysis of variance.ResultsSixteen subjects (8 female) completed each part. The pain tolerance threshold (PTT) for electrical stimulation was increased (all P < 0.05) compared to placebo for (S)‐ketamine (+10.1%), phenytoin (+8.5%) and pregabalin (+10.8%). The PTT for mechanical pain was increased by pregabalin (+14.1%). The cold pressor PTT was increased by fentanyl (+17.1%) and pregabalin (+46.4%). Normal skin heat pain detection threshold was increased by (S)‐ketamine (+3.3%), fentanyl (+2.8%) and pregabalin (+4.1%). UVB treated skin pain detection threshold was increased by fentanyl (+2.6%) and ibuprofen (+4.0%). No differences in conditioned pain modulation were observed.ConclusionThis study shows that these pain models are able to detect changes in pain thresholds after administration of different classes of analgesics in healthy subjects. The analgesic compounds all showed a unique profile in their effects on the pain tasks administered.

Published: November 2016

A child's first words mark the emergence of a uniquely human ability. Theories of the developmental steps that pave the way for word production have proposed that either vocal or gestural precursors are key. These accounts were tested by assessing the developmental synchrony in the onset of babbling, pointing, and word production for 46 infants observed monthly between the ages of 9 and 18 months. Babbling and pointing did not develop in tight synchrony and babble onset alone predicted first words. Pointing and maternal education emerged as predictors of lexical knowledge only in relation to a measure taken at 18 months. This suggests a far more important role for early phonological development in the creation of the lexicon than previously thought.

BackgroundEvidence‐based approaches and early intervention have improved the long‐term prognosis of individuals with schizophrenia. However, little is known about the therapeutic processes involved in individual therapy in first‐episode psychosis. A comprehensive psychosocial/psychiatric programme for this population, NAVIGATE, includes an individual therapy component, individual resiliency training (IRT). Fidelity of clinicians’ adherence to the IRT protocol has been collected to ensure proper implementation of this manual‐based intervention. These data can provide insight into the elements of the therapeutic process in this intervention.Materials and MethodsTo achieve this goal, we first examined the factor structure of the IRT fidelity scale with exploratory factor analysis. Second, we explored the relationships among the IRT fidelity ratings with clinician years of experience and years of education, as well as client's baseline symptom severity and duration of untreated psychosis.Results and ConclusionsResults supported a 2‐factor structure of the IRT fidelity scale. Correlations between clinician years of education and fidelity ratings were statistically significant.

AbstractIntroductionOutcome of patients with standard‐risk (SR) multiple myeloma (MM) has improved; however, subsets of patients do worse than expected. We sought to identify the factors associated with inferior outcome.MethodsWe evaluated 51 patients with SR MM that received upfront autologous hematopoietic stem cell transplantation (auto‐HCT) after induction and had a progression‐free survival (PFS) of ≤18 months.ResultsThe median age of patients was 61 yr. Forty‐one (80%) patients received induction with immunomodulatory drugs, proteosome inhibitors, or combination of both. The overall response rate (ORR) after auto‐HCT was 96% (stringent complete response 23%, complete response 10%, very good partial response 22%, and partial response 39%). The median PFS was 7.8, and median overall survival (OS) was 56.3 months. On univariate analysis, concurrent light‐chain amyloidosis (AL) was associated with inferior PFS [hematological response (HR); 2.51, 95% CI; 0.64–10.58, P = 0.03] and occurrence of soft tissue plasmacytoma was associated with a significantly shorter OS (HR: 3.05, 95% CI: 0.57–16.29, P = 0.02).ConclusionOur analysis suggests that concurrent AL and soft tissue plasmacytoma were associated with shorter PFS and OS, respectively. Heterogeneity in clinical outcome of SR MM merits better tools for prognostication, such as gene expression profiling and minimal residual disease assessment to identify high‐risk patients.

Published: November 2016

Background and purposeProteinuria and estimated glomerular filtration rate (eGFR) are indicators of renal function. Whether proteinuria better predicts outcome than eGFR in stroke patients treated with intravenous thrombolysis (IVT) remains to be determined.MethodsIn this explorative multicenter IVT register based study, the presence of urine dipstick proteinuria (yes/no), reduced eGFR (<60 ml/min/1.73 m2) and the coexistence of both with regard to (i) poor 3‐month outcome (modified Rankin Scale score 3–6), (ii) death within 3 months and (iii) symptomatic intracranial hemorrhage (ECASS‐II criteria) were compared. Unadjusted and adjusted odds ratios (ORs) with 95% confidence intervals were calculated.ResultsAmongst 3398 patients, 881 (26.1%) had proteinuria and 623 (18.3%) reduced eGFR. Proteinuria [ORadjusted 1.65 (1.37–2.00) and ORadjusted 1.52 (1.24–1.88)] and reduced eGFR [ORadjusted 1.26 (1.01–1.57) and ORadjusted 1.34 (1.06–1.69)] were independently associated with poor functional outcome and death, respectively. After adding both renal markers to the models, proteinuria [ORadjusted+eGFR 1.59 (1.31–1.93)] still predicted poor outcome whilst reduced eGFR [ORadjusted+proteinuria 1.20 (0.96–1.50)] did not. Proteinuria was associated with symptomatic intracranial hemorrhage [ORadjusted 1.54 (1.09–2.17)] but not reduced eGFR [ORadjusted 0.96 (0.63–1.62)]. In 234 (6.9%) patients, proteinuria and reduced eGFR were coexistent. Such patients were at the highest risk of poor outcome [ORadjusted 2.16 (1.54–3.03)] and death [ORadjusted 2.55 (1.69–3.84)].ConclusionProteinuria and reduced eGFR were each independently associated with poor outcome and death but the statistically strongest association appeared for proteinuria. Patients with coexistent proteinuria and reduced eGFR were at the highest risk of poor outcome and death.

Background and purposeThe percentage of patients with clinical total anterior circulation infarct (TACI) syndrome treated with reperfusion therapies in the absence of intracranial large‐vessel occlusion (ILVO) was determined and their characteristics and outcome are described.MethodsData from a population‐based, prospective, externally audited registry of all stroke patients treated with intravenous thrombolysis (IVT) and endovascular therapies in Catalonia from January 2011 to December 2013 were used. Patients with a baseline TACI and initial stroke severity measured by the National Institute of Health Stroke Scale (NIHSS) ≥ 8, evaluated less than 4.5 h post‐onset, for whom a vascular study prior to treatment was available (n = 1070) were selected. Clinical characteristics, outcome and radiological data for patients treated with IVT alone (n = 605) were compared between those with detected ILVO (n = 474) and non‐ILVO patients (n = 131).ResultsA total of 1070 patients met study criteria; non‐ILVO was found in 131 (12.2%). Analysing the 605 patients treated only with IVT, no significant differences were found between non‐ILVO and ILVO patients in age, sex, risk factors, time‐to‐treatment and type of radiological studies performed. Although non‐ILVO patients had lower initial stroke severity (P < 0.001) and a better prognosis (P = 0.001), 51.3% had a poor outcome and 16% were deceased at 90 days. In 66.4% of patients without ILVO, a recent anterior territorial infarct was detected.ConclusionsIntracranial artery patency was observed in 12.2% of TACI patients evaluated within 4.5 h. Although absence of ILVO was associated with slightly better prognosis, more than half had a poor outcome at 3 months.
