A proposed hybrid storage assignment framework: a case study
Authors: Sharma Sanjay , Shah Bhavin 
Published: July 2015

Purpose
– A hybrid storage assignment (combination class-volume-based) framework considering quality proximity, customer and material categorization are key distinguished contents of this paper. In spite of using individual storage allocation approach, the hybrid allocation policy performs better under certain environment. The paper aims to discuss these issues.

Design/methodology/approach
– Although it has been proved that every storage assignment policy has their advantages and limitations, one or more storage assignment policies with combination of zoning and layout design can be used together for further improvement. The authors have conducted this study at warehouse of a manufacturing firm that produce only single product with varieties of material and quality criteria. Picking optimization includes elimination of non-value-added activities like unwanted forklift and package movements, time and distance traveled for retrieval as well as storage. Other allied operations with respect to customer acceptance level and resource utilization are also considered.

Findings
– The time and distance from manufacturing point to storage location are accountable as it also contributes to picking performance.

Originality/value
– Quality-based cluster analysis is carried out to find out closeness among customers, which is used to propose algorithm with new layout design, zoning and storage allocation policy.

Authors: Ghoddousi Parviz , Poorafshar Omid , Chileshe Nicholas , Hosseini M. Reza 
Published: July 2015

Purpose– The purpose of this paper is twofold. First, it aims to highlight the main factors and items affecting the productivity of construction projects, based on the perceptions of CEOs in construction companies in Iran. Second, the study compares the elicited CEOs’ perceptions against the findings of studies based on the views of such as project managers, middle managers and employees in other levels.Design/methodology/approach– The study drew upon literature on construction work to develop a conceptual model. Further, a total of 60 CEOs from road construction companies were surveyed using a five-point Likert scale questionnaire to generate the data. The collated data were categorised and ranked according to the CEOs perceived level of importance using the relative importance index.Findings– The findings highlight the main factors and items affecting labour productivity in construction projects in Iran as perceived by CEOs, which are mainly of human resources management nature and could be attributed to motivation and managerial policy aspects. The study also recognises that factors associated with the working environment particularly safety and health are perceived as insignificant by Iranian CEOs which could be a concern for the Iranian construction industry. The discussions shed some light on the discrepancies between the perceptions of CEOs and previous studies in regards to major determinants of productivity in the construction context.Originality/value– This study is the first study aiming at discussing the perceptions of CEOs of construction companies active in construction projects in Iran. As such, the study highlights the standpoint of the main decision makers in construction companies in regards to labour productivity in the construction sector. Thus, the key contribution of the present study is providing insight into the perceptions of CEOs, who play the most vital role in strategic development of construction companies whereas previous studies have mostly focused on project or middle managers having a lower influence in determining the strategic plans of companies.
Readers’ advisory: can we take it to the next level?
Authors: Dali Keren 
Published: July 2015

Purpose– The purpose of this paper is to analyze a number of issues related to both education for and the practice of reading and readers’ advisory in library and information science (LIS). Written from the standpoint of an LIS educator, the paper is addressed to LIS professors, future and current LIS students, and public services librarians working in all types of libraries, including academic and special, because the practice of reading is no longer limited to school and public libraries. Librarians’ expertise can also benefit a larger community outside of the library walls, which would take outreach and embeddedness to an entirely new level.Design/methodology/approach– The paper analyzes the situation in LIS education and reading practices based on a vast array of published sources and the author’s personal experience as an LIS educator.Findings– The following problematic points are raised: modeling reading work and education for reading after information services and information science education, respectively; outdated pedagogical approaches; insufficient user orientation and excessive focus on materials; limiting reading activities to one to two types of libraries; insufficient community outreach; and, in general, the prevalence of responsive rather than proactive practices.Originality/value– The paper proposes some solutions for the identified problems, the implementation of which depends on the collective effort and the collective will. However, it does not offer a particularly optimistic or upbeat view on the possibility of swift and sweeping changes.

Authors: Frijns Bart , Tourani-Rad Alireza 
Published: July 2015

Purpose
– This paper aims to investigate the risk-adjusted performance of the KiwiSaver Growth funds for the period 2007-2013 in New Zealand.

Design/methodology/approach
– Performance attribution regressions are used to measure risk-adjusted performance of KiwiSaver funds.

Findings
– This paper found that there is no evidence of systematic risk-adjusted outperformance of KiwiSaver Growth funds, and in several cases, there is evidence of significant underperformance. This paper further reports substantial variation in the amount of risk-taking, and local and international stock market exposure of KiwiSaver Growth funds.

Originality/value
– KiwiSaver is becoming an increasingly important investment vehicle for many New Zealanders saving for retirement. This is the first paper that considers the performance of KiwiSaver funds.
GAAP-adjusted earnings disclosures by New Zealand companies
Authors: Rainsbury Liz , Hart Carol , Buranavityawut Nonthipoth 
Published: July 2015

Purpose
– This paper aims to examine motivations for the reporting of generally accepted accounting practice (GAAP)-adjusted earnings by New Zealand companies.

Design/methodology/approach
– The study uses multivariate analysis of data from New Zealand company annual reports for the period from 2004 to 2012.

Findings
– Evidence suggests that management of some New Zealand firms are motivated to use GAAP-adjusted earnings to provide a more favourable impression of earnings. However, across firms, these adjusted earnings provide a better predictor of future earnings and provide more value-relevant information to the market than GAAP earnings. Thus, a desire to disclose a more accurate indicator of permanent earnings appears to be a strong factor in the reporting of GAAP-adjusted earnings.

Research limitations/implications
– The study uses firms listed on the New Zealand share market. The number of firms examined is small, but we compensate by studying the entire population, thus avoiding sampling issues. The results suggest that New Zealand’s regulatory response of recommending guidelines for reporting alternative earnings measures is appropriate.

Originality/value
– The study contributes to the literature on the relationship between reporting statutory earnings and non-GAAP earnings. It uses a period that includes three major events in the New Zealand economy and reporting environment: the adoption of international financial reporting standards, a change in tax law and the global financial crisis. Recognition of these events allows us to better interpret the GAAP-adjusted reporting practices taken by managers.
“He’s taken a dive”
Authors: Webb Tom , Thelwell Richard 
Published: July 2015

Purpose– The purpose of this paper is to consider the cultural similarities and differences between elite referees concerning their preparation and performance in dealing with reduced player behaviour.Design/methodology/approach– Semi-structured interviews were employed to collect the data. The 37 participants from England, Spain and Italy were selected through the use of purposive sampling, and all were working in the field of refereeing as current elite-level referees, ex-elite-level referees, referee assessors, referee coaches, or managers and administrators from bodies that manage and train referees. Inductive content analysis was employed to generate themes from the raw data.Findings– Referees have identified particular issues related specifically to player behaviour and also identified specific traits pertaining to players from certain countries. Furthermore, results demonstrate that referees have begun to alter their preparation and performance due to the pressure they perceive exists within association football and, more specifically, from the players themselves.Originality/value– This study is the first to compare cross-cultural elite referee responses regarding their preparation and performance related to player behaviour.

Published: July 2015

Purpose
– The purpose of this paper is to evaluate the influence of assembly parameters on lead-free solder joints reliability in Package-on-Package (PoP) Technology and demonstrate factors important for this issue.

Design/methodology/approach
– Two types of soldering materials and three different assembly procedures were used for assembly of PoP system. The reliability properties of assembled PoP systems were investigated using accelerated aging and periodic resistance measurements of daisy-chain solder joints systems. The purpose of such approach was to determine which soldering material (flux or solder paste) as well as which assembly process parameter (dipping depth of upper component in soldering material), would provide better reliability properties of the solder joints in the PoP system.

Findings
– It was stated that both selected flux and solder paste dedicated to assembly of PoP systems can be utilized in soldering of PoP applications. More reliable PoP systems applications require larger attention regarding materials selection and assembly parameters. It is recommended 50 per cent dipping depth of ball’s height into soldering material during upper PoP component assembly for more reliable applications. For less demanding PoP systems, the process window from 30 up to 70 per cent is acceptable. All observed failures after thermal shocks occurred in upper PoP components.

Originality/value
– This paper explains how materials and assembly parameters have influence on lead-free solder joints reliability in PoP systems. Especially, influence of process window for dipping procedure of upper components balls into soldering material was presented.

SummaryThe Sporomusa genus comprises anaerobic spore‐forming acetogenic bacteria that stain Gram‐negative. Sporomusa species typically grow with one‐carbon substrates and N‐methylated compounds. In the degradation of these compounds methyltransferases are involved. In addition, Sporomusa species can grow autotrophically with H2 and CO2, and use a variety of sugars for acetogenic growth. Here we describe a genome analysis of Sporomusa strain An4 and a proteome analysis of cells grown under five different conditions. Comparison of the genomes of Sporomusa strain An4 and Sporomusa ovata strain H1 indicated that An4 is a S. ovata strain. Proteome analysis showed a high abundance of several methyltransferases, predominantly trimethylamine methyltransferases, during growth with betaine, whereas trimethylamine is one of the main end‐products of betaine degradation. In methanol degradation methyltransferases are also involved. In methanol‐utilizing methanogens, two methyltransferases catalyse methanol conversion, methyltransferase 1 composed of subunits MtaB and MtaC and methyltransferase 2, also called MtaA. The two methyltransferase 1 subunits MtaB and MtaC were highly abundant when strain An4 was grown with methanol. However, instead of MtaA a methyltetrahydrofolate methyltransferase was synthesized. We propose a novel methanol degradation pathway in Sporomusa strain An4 that uses a methyltetrahydrofolate methyltransferase instead of MtaA.
Factors related to perceived parental approval of adult sons’ and daughters’ heterosexual engagements
Authors: Larson Jeffry H. , Malnar Marietta , Busby Dean 
Published: July 2015

This study examined factors that may predict perceived parental approval of an adult child's heterosexual engagement relationship as parental approval has been shown in previous studies to be an important predictor of later couple quality and stability. A total of 4175 engaged individuals completed the RELATE inventory. Among the items in the questionnaire were measures of perceived parental approval of the relationship, parents’ marital quality, autonomy from the family of origin and couple relationship quality. The individuals also reported their age, education, length of their relationship, parents’ marital status and parents’ socioeconomic status. The results showed that adult sons’ and daughters’ age, parental marital quality, autonomy and couple relationship quality predicted parental approval. Length of the relationship and parental marital status did not influence parental approval for either gender. Clinical implications and directions for future research are discussed.Practitioner points

Perceived parental approval of an adult child's heterosexual engagement relationship should be assessed with engaged couples.
Assess current couple relationship as this is not always as high as we may assume.
Perceived quality of each partner's parents’ marriage should be discussed as to how it may affect perceptions of parental approval.
Assess differentiation of self in the family of origin and increase it using transgenerational couple therapy approaches.
Insecticide‐mediated behavioral avoidance by bean bug, Riptortus pedestris (Heteroptera: Alydidae)
Authors: Maharjan Rameswor , Jung Chuleui 
Published: July 2015

AbstractBean bug, Riptortus pedestris (Fabricius) (Heteroptera: Alydidae), is an economically important pest of soybean and tree fruit. Behavioral responses of R. pedestris to olfactory cues from insecticide‐treated foliage were assessed in a Y‐tube olfactometer. Ten insecticides were applied to kidney bean plants at the recommended dosage, and then bug avoidance was assessed at 0, 3, 5, 7 and 13 days after treatment (DAT). Each bug was allowed 5 min to choose one of the olfactometer's arms. Even though the degree of avoidance was variable to the insecticides tested, bean bugs significantly avoided the insecticide‐treated leaf. The pyrethroid bifenthrin was the most avoided of the insecticides tested. In all treatments, avoidance decreased as DAT increased. Also, the movement speed was higher to the untreated leaf than to the insecticide‐treated leaf. The degree of avoidance was positively correlated to the vapor pressure of the chemical; this finding implies the interaction of the treated chemicals and plant volatiles may be used as cues for bean bug selection of the host‐plant.

Published: July 2015

SummaryThe foliar pathogen Pseudomonas syringae pv. tomato DC3000 (Pst) leads to consistent losses in tomato crops, urging to multiply investigations on the physiological bases for its infectiveness. As other P. syringae pathovars, Pst is equipped with photoreceptors for blue and red light, mimicking the photosensing ability of host plants. In this work we have investigated Pst strains lacking the genes for a blue‐light sensing protein (PstLOV), for a bacteriophytochrome (PstBph1) or for heme‐oxygenase‐1. When grown in culturing medium, all deletion mutants presented a larger growth than wild‐type (WT) Pst under all other light conditions, with the exception of blue light which, under our experimental conditions (photon fluence rate = 40 μmol m−2 s−1), completely suppressed the growth of the deletion mutants. Each of the knockout mutants shows stronger virulence towards Arabidopsis thaliana than PstWT, as evidenced by macroscopic damages in the host tissues of infected leaves. Mutated bacteria were also identified in districts distant from the infection site using scanning electron microscopy. These results underscore the importance of Pst photoreceptors in responding to environmental light inputs and the partial protective role that they exert towards host plants during infection, diminishing virulence and invasiveness.
Normality of stock returns with event time clocks
Authors: Ling Xin 
Published: July 2015

AbstractWe introduce a different way to measure time using event clocks, with which we can observe a normal distribution of intraday stock returns. Most finance studies employ a ‘default’ time measurement that uses a calendar clock. Cumulative evidence from prior literature shows that returns with a calendar clock follow a distribution with an excess kurtosis and a heavier tail, relative to a normal distribution. We examine the distribution of intraday stock returns using different clocks. We find that returns do not follow a normal distribution with a traditional calendar clock, but do follow a normal distribution when event clocks are applied.

Published: July 2015

AbstractAimThe objective of this systematic review was to investigate whether breastfeeding decreases the risk of malocclusions.MethodsSix databases were systematically searched to the end of October 2014. Observational and interventional studies were included. Breastfeeding was evaluated in three categories: (i) ever versus never; (ii) exclusive versus absence of exclusive; and (iii) longer periods versus shorter periods. All types of malocclusion were considered as the outcome. Pooled adjusted odds ratio and its 95% confidence interval (95%CI) were obtained from meta‐analyses. Heterogeneity was assessed with both the Q‐test and the I‐square. Funnel plots and Egger's test were employed to assess publication bias.ResultsForty‐eight studies were included in the systematic review, and 41 were included in the overall meta‐analysis (n = 27 023 participants). Subjects who were ever breastfed were less likely to develop malocclusions than those never breastfed (OR 0.34; 95% CI 0.24; 0.48), those who were exclusively breastfed presented lower risk to present malocclusion than those with absence of exclusive breastfeeding (OR 0.54; 95% CI 0.38; 0.77), and subjects longer breastfed were less likely to have malocclusions than those shorter breastfed (OR 0.40; 95% CI 0.29; 0.54).ConclusionBreastfeeding decreases the risk of malocclusions.

Published: July 2015

AimPharmacogenetic studies have identified the presence of the HLA‐A*31:01 allele as a predictor of cutaneous adverse drugs reactions (ADRs) to carbamazepine. This study aimed to ascertain the preferences of patients and clinicians to inform carbamazepine pharmacogenetic testing services.MethodsAttributes of importance to people with epilepsy and neurologists were identified through interviews and from published sources. Discrete choice experiments (DCEs) were conducted in 82 people with epilepsy and 83 neurologists. Random‐effects logit regression models were used to determine the importance of the attributes and direction of effect.ResultsIn the patient DCE, all attributes (seizure remission, reduction in seizure frequency, memory problems, skin rash and rare, severe ADRs) were significant. The estimated utility of testing was greater, at 0.52 (95% CI 0.19, 1.00) than not testing at 0.33 (95% CI –0.07, 0.81). In the physician DCE, cost, inclusion in the British National Formulary, coverage, negative predictive value (NPV) and positive predictive value (PPV) were significant. Marginal rates of substitution indicated that neurologists were willing to pay £5.87 for a 1 percentage point increase in NPV and £3.99 for a 1 percentage point increase in PPV.ConclusionThe inclusion of both patients' and clinicians' perspectives represents an important contribution to the understanding of preferences towards pharmacogenetic testing prior to initiating carbamazepine. Both groups identified different attributes but had generally consistent preferences. Patients' acceptance of a decrease in treatment benefit for a reduced chance of severe ADRs adds support for the implementation of HLA‐A*31:01 testing in routine practice.
Conventional versus accelerated corneal collagen cross‐linking in the treatment of keratoconus
Authors: Ng Alex Lap Ki , Chan Tommy CY , Cheng Arthur CK 
Published: July 2015

AbstractBackgroundThis study aims to compare the effect of conventional corneal collagen cross‐linking (CXL) with accelerated corneal collagen cross‐linking in treatment of keratoconus.DesignA comparative interventional study was employed.ParticipantsParticipants were consecutive cases of progressive keratoconus receiving either conventional (3 mW/cm2 irradiance for 30 min) or accelerated CXL (9 mW/cm2 irradiance for 10 min).MethodsClinical and topographic parameters were compared between the two groups. Postoperative corneal stromal demarcation line was measured using anterior segment optical coherence tomography.Main Outcome MeasuresClinical and topographic parameters such as corrected distant visual acuity (CDVA), maximum keratometry (Kmax), mean keratometry (Kmean), demarcation line depth were gathered from medical records.ResultsThere were a total of 26 eyes with an average follow up of 13.9 ± 6.3 months. Fourteen eyes received conventional CXL, and 12 eyes had accelerated CXL. In the conventional CXL group, CDVA improved significantly (P = 0.021). There was also a significant reduction in Kmax (P = 0.003) and Kmean (P = 0.002). In the accelerated CXL group, no significant changes were found in CDVA (P = 0.395), Kmax (P = 0.388) and Kmean (P = 0.952) postoperatively. A significantly greater reduction in Kmax and Kmean were seen in conventional CXL compared to its accelerated counterpart (P = 0.001 and 0.015, respectively). The demarcation line was deeper in eyes with conventional CXL (P = 0.013), and the depth correlated significantly with the change in Kmean (r = −0.432, P = 0.045).ConclusionConventional and accelerated CXL are effective in stabilizing keratoconus progression after a mean of 12 months. Patients undergoing conventional CXL showed clinical improvement with greater corneal flattening, which correlated with a deeper corneal stromal demarcation line. This current study is the first to report such correlation.
