Constructing construction careers: the case for the building trades
Authors: Callanan Gerard , Perri David 
Published: March 2020

PurposeThis paper discusses the well-publicized labor shortages in the building trades, reviews the causes for the deficiencies, and presents prescriptions for how career counselors and schools can play a critical role in encouraging young adults to consider construction occupations.Design/methodology/approachUsing data from government agencies, trade organizations, and scholarly publications, this paper describes the categories of the building trades as well as their employment trends and compensation prospects. It also reviews the personal and environmental factors that could lead to the “construction of a construction career.”FindingsThis article documents the reasons for the labor shortages in the construction industry and then offers recommendation on how younger adults could be encouraged to consider the building trades as viable career alternatives.Social implicationsLabor shortages in the construction industry have a direct and indirect deleterious effect on the economic well-being of every country. This article provides suggestions on how to inspire young adults to consider the building trades as worthwhile career pursuits.Originality/valueThere is a limited amount of scholarly attention given to career decision making related to occupations that do not require a college degree, including the building trades. This paper attempts to fill this gap in the literature by focusing on the individual characteristics and environmental factors that might prompt consideration of a career in the building trades. It also describes the educational, governmental, and corporate initiatives that work to encourage individuals, working in conjunction with their career counselors, to consider careers in the construction industry.
Validating effective managerial behaviors for the hospitality industry
Authors: Michel John W. , Tews Michael J. , Tracey J. Bruce 
Published: March 2020

Purpose
This paper aims to examine the validity of the Managerial Practices Survey (MPS). Despite voluminous work on leadership styles, few studies have examined the specific behaviors of effective leaders in the hospitality industry.

Design/methodology/approach
Data were collected from two different samples through surveys to assess the construct validity of the MPS in the hospitality industry.

Findings
The proposed four meta-category and 18 component behavior MPS framework fit the data well and both the meta-categories and component behaviors were predictive of leadership effectiveness.

Practical implications
While meta-categories may be conceptually and theoretically relevant, component leadership behaviors are more useful for applied uses, such as leadership development. When behaviors are assessed at the component level, leaders can be provided with feedback and coaching on the specific actions they can take to improve their decision-making and problem-solving capabilities and ultimately become more effective leaders.

Originality/value
This research provides a validation of the MPS and useful insights for which behaviors are most useful for managers in hospitality contexts.

Published: March 2020

PurposeThis paper is the first comprehensive investigation of the shipping industry's efficiency in five countries from the ASEAN region: Malaysia, Singapore, the Philippines, Thailand and Vietnam.Design/methodology/approachEmploying Data Envelopment Analysis and Stochastic Frontier Analysis, this paper compares efficiency dynamics of 45 international and offshore shipping providers engaged in fishing and ferrying.FindingsThe results indicate consistently diminishing efficiency from 2011 to 2017, a phenomenon that persists even in the traditionally efficient companies. Thereafter, this paper develops AltmanZ-scores for the sampled companies and notice that despite rising inefficiency, most firms remain unencumbered by bankruptcy concerns, especially those with large capital buffers.Research limitations/implicationsIn general, this paper observes a negative relationship between bankruptcy risk and efficiency. Furthermore, the paper notices that reducing inputs does not help boost efficiency.Originality/valueIn terms of novel contributions, this paper is the first (to the best of knowledge) to set aZ-score for the ASEAN-based shipping companies.

Authors: Liu Xiaoxue , Zhang Yahui , Xie Suming , Zhang Qiang , Guo Hanfei 
Published: March 2020

PurposeThe car body stiffness of express freight sliding side covered wagon decreased for the sliding and the resonance vibration based on the flexible car body has affected the dynamics performances. Dynamic loading will cause fatigue cracks and eventually lead to fatigue failure of the car body. This paper aims to investigate the influence of car body flexibility on the evaluation of the failure.Design/methodology/approachIn this paper, the railway vehicles random analysis procedure (RVRAP) is employed to study the fatigue failure of the rigid-flexibility model. Following the analysis process, the rigid-flexibility model is established and four contrastive schemes for simulation analysis are designed. To verify the results, an experimental test using the real car body structure on the vibration test plant is carried out; the RMS of dynamic stress is obtained and compared with the simulation results.FindingsThe results show that the flexibility of the car body has a crucial influence on the fatigue life.Originality/valueThe reliability is verified regarding the use of RVRAP at an appropriate stage on the antifatigue design of the vehicle.

Authors: Wang Hongchang , Jin Cheng , Liu Houyu , Xue Zhiqiang 
Published: March 2020

PurposeAs an important part of steel bridge deck pavement, if waterproof adhesive layer performance does not meet requirements, numerous kinds of bridge deck pavement distress may be encountered. To study the adhesive behavior of rubber asphalt waterproof adhesive layers in steel bridge gussasphalt pavement, the pull-off and direct-shear tests have been used in the study to mechanically simulate steel bridge deck pavement under vehicles loading.Design/methodology/approachSeveral potentially influential factors associated with the adhesive strength of rubber asphalt are investigated including temperature, spraying quantity and environmental conditions.FindingsResults indicate that rubber asphalt was associated with good performance with respect to its use as a waterproof adhesive layer; simulated performance was negatively correlated with increasing temperatures. A necessary spraying quantity of 0.4 Lm-2is required for appropriate adhesive strength of the composite structure, with a decrease in adhesive strength noted when spraying quantity is significantly greater or less than this.Originality/valueThe current paper presents an examination of the adhesive performance of a rubber asphalt adhesive layer on steel bridge deck pouring construction, while additionally examining potentially influential factors and conditions via use of both pull-off and shear tests.
A study on the effect of long-term orientation and risk propensity on resilience
Authors: Sulphey M.M. 
Published: March 2020

PurposeResilience is the ability to recover and once again adapt former behaviours that have characterized an individual, prior to the period of disruption. It requires various qualities, resources and power to recover immediately after a traumatic event and is found related to a number of variables and concepts. The purpose of the study is to examine the relationship of long-term orientation and risk propensity on resilience using structural equation modelling (SEM).Design/methodology/approachR Program was used to perform SEM on the data collected online from 357 samples using three standardized questionnaires to measure long-term orientation, risk propensity and resilience.FindingsIt was found that long-term orientation and its factors, respect for tradition and planning, were having a positive relationship with resilience. No relationship was found between risk propensity and resilience.Originality/valueA fair review of literature has found that no previous studies have examined the relationship between long-term orientation and risk propensity on resilience. The present study is a modest effort towards this direction. The findings are indeed significant and contribute substantially to literature.

Published: March 2020

PurposeLife cycle costing (LCC) has become increasingly important in construction projects over the last decades. However, limited empirical studies have been carried out on the factors influencing its application in building projects, particularly in developing countries. The purpose of this study is to address this gap in knowledge within the Nigerian context.Design/methodology/approachPrimary data were used through the administration of questionnaires to practising quantity surveying firms in Lagos State, Nigeria. The data obtained were analysed using both descriptive and inferential statistical tools including percentages, mean item score and factor analysis.FindingsThe study identified 47 barriers to the application of LCC, and the analysis of the ranking revealed that 35 (of 47) identified barriers were considered important. Factor analysis grouped the identified barriers into four key factors namely, professional incompetence; cost implications; administrative factor and procurement options.Practical implicationsThis research is important by providing the empirical evidence on the barriers to the application of LCC in developing countries, particularly in Nigeria. For instance, the identification of important barriers to LCC use will enlighten the construction professionals to be trained in the practicalities of LCC. Moreover, the study provides implications for construction stakeholders (including governments) to draw policy recommendations that will positively improve the use of LCC in the construction industry, especially in developing countries.Originality/valueThe study will be beneficial to all the construction stakeholders by broadening their awareness about the barriers to LCC use in Nigeria and developing countries at large.

Authors: Gámez-Pérez Karla M. , Sarmiento Ana Maria , Garcia-Reyes Heriberto , Velázquez-Martínez Josué C. 
Published: March 2020

PurposeThe increase in the supply chain complexity demands new professionals who are able to deal with the new challenges faced nowadays. The purpose of this work is to propose an international university–industry collaboration model to develop supply chain management competences in students as a tool for the training of future professionals.Design/methodology/approachThis study proposes an international collaboration model to develop supply chain competences. The model consists of three main phases from the genesis of the collaboration to the assessment of the competence development. This study validates the model collaborating with one of the largest retailer companies in Mexico.FindingsResults identify collaboration good practices and point at possible improvements for the next model iteration. This study identifies four key supply chain competences as part of this model. Three didactic approaches (i.e. guidance methods) and two student’s involvement schemes were tested. The results show that professors acting as an advisor (i.e. acting as a guider without telling student directly what to do or how to do it) plus a voluntary student’s involvement in the project promote better competence development.Originality/valueThe first contribution of this research is the definition of an international collaboration model that promotes competence-based education. Also, this study documents good practices for this type of partnership. The second one refers to a large-scale model validation (i.e. 14-week experiment in nine different regions of Mexico involving a retail company, 20 professor-researchers and more than 100 students). The third contribution includes the assessment of different levels of competences development using diverse students’ participation schemes and professor’s guidance methods.
ArsH protects Pseudomonas putida from oxidative damage caused by exposure to arsenic
Authors: Páez‐Espino A. David , Nikel Pablo I. , Chavarría Max , de Lorenzo Víctor 
Published: March 2020

SummaryThe two As resistance arsRBC operons of Pseudomonas putida KT2440 are followed by a downstream gene called arsH that encodes an NADPH‐dependent flavin mononucleotide reductase. In this work, we show that the arsH1 and (to a lesser extent) arsH2 genes of P. putida KT2440 strengthened its tolerance to both inorganic As(V) and As(III) and relieved the oxidative stress undergone by cells exposed to either oxyanion. Furthermore, overexpression of arsH1 and arsH2 endowed P. putida with a high tolerance to the oxidative stress caused by diamide (a drainer of metabolic NADPH) in the absence of any arsenic. To examine whether the activity of ArsH was linked to a direct action on the arsenic compounds tested, arsH1 and arsH2 genes were expressed in Escherichia coli, which has an endogenous arsRBC operon but lacks an arsH ortholog. The resulting clones both deployed a lower production of reactive oxygen species (ROS) when exposed to As salts and had a superior endurance to physiological redox insults. These results suggest that besides the claimed direct action on organoarsenicals, ArsH contributes to relieve toxicity of As species by mediating reduction of ROS produced in vivo upon exposure to the oxyanion, e.g. by generating FMNH2 to fuel ROS‐quenching activities.
Increasing Methamphetamine Detection in Cases of Early Childhood Fatalities
Authors: Kenneally Michaela , Byard Roger W. 
Published: March 2020

AbstractAge and organ maturity can influence drug toxicity in children; however, most clinical data and literature are based on drug concentrations in adults. Therefore, the interpretation of drugs detected in children is often difficult or not possible. Retrospective reviewing of pathology and toxicology information from postmortem cases may assist in future interpretations or identify drug trends. A search of the Forensic Science SA case files was undertaken over 15 years from January 2002 to December 2016 for all children (<13 years). Of the 412 pediatric coronial cases, toxicological information was available on 373. At least one drug was detected in 94 cases with paracetamol, ibuprofen, codeine and hospital‐administrated lignocaine and morphine among the most commonly detected agents. Methamphetamine, one of the most commonly abused illicit drugs in Australia, was found in seven cases. In the methamphetamine cases, deaths were associated with shared sleeping in three, pneumonia in one, and stillbirth in one. Methamphetamine was considered potentially contributory to death in two cases. The causes of death in the remaining two cases were undetermined. As six of the seven positive cases occurred in the 2012–2016 (n = 106) timeframe, an increase has occurred over recent years in the number of infants and young children presenting to forensic autopsy in South Australia who have detectable concentrations of methamphetamine. If this is an indication of a more generalized increased childhood exposure in the community there may be significant long‐term physical and psychological effects.

Published: March 2020

AbstractBackgroundA superior lumbar hernia is a posterior ventral hernia that is rarely encountered in the clinical setting. However, no standard operative strategy exists for superior lumbar hernia repair at present.MethodsTwelve patients with primary superior lumbar hernia who underwent sublay repair via the retroperitoneal space with the Kugel patch between December 2008 and June 2019 were included in this study. The demographic, peri‐operative and post‐operative data of the patients were collected to analyse the effectiveness of this technique.ResultsAll patients underwent an uneventful operation. The median operative time was 60 min, and the median blood loss was 35 mL. The median hernia defect area was 16 cm2. Five medium‐sized Kugel patches (11 cm × 14 cm) and seven large‐sized Kugel patches (14 cm × 17 cm) were used for the repairs. The median visual analogue scale score on post‐operative day 1 was 3. The median time to removal of drainage was 3 days. The median duration of the hospital stay was 3 days. No serious post‐operative complications, including seroma, haematoma, incision or mesh infection, recurrence and chronic pain, occurred during the follow‐up period.ConclusionSublay repair for primary superior lumbar hernia with the Kugel patch shows benefits including a reliable repair, minimal invasiveness and few post‐operative complications.

AbstractThis study aims to evaluate the anti–heat stress effect of Chinese herbal medicine (CHM) prescription, rumen‐protected γ‐aminobutyric acid (RP‐GABA), and CHM plus RP‐GABA co‐medication on growth performance, apparent digestibility, and serum parameters in heat‐stressed beef cattle. Forty beef cattle were randomly divided into four groups. Control group was supplied with basal diet, while CHM, γ‐aminobutyric acid (GABA), and CHM + GABA groups were, respectively, supplied with CHM, RP‐GABA, and CHM plus RP‐GABA in basal diet. Our result indicated that CHM + GABA elevated apparent digestibility including crude protein, Ca, P, crude fat (CF) (p < .01), and neutral detergent fiber (NDF) (p < .05), but no difference was found with CF and NDF digestibility both in CHM and GABA group (p > .05). More importantly, average daily gain (ADG) was improved in CHM, GABA, and CHM + GABA groups, while average daily feed intake (ADFI) significantly increased only in CHM + GABA groups (p < .05). Meanwhile, CHM + GABA displayed notably more positive effect in serum hormones, immune globulin, ions contents, and blood inflammatory cytokines than other treatment groups and control group. These results demonstrated that both CHM and GABA are effective in alleviating heat stress response and the co‐medication has a synergistic effect on anti–heat stress.
Testing hypothetical bias in a framed field experiment
Authors: Brouwer Roy , Tarfasa Solomon 
Published: March 2020

AbstractHypothetical bias is tested based on inter‐ and intra‐respondent comparisons of choice behavior, applying a hypothetical and real choice experiment. The inter‐respondent comparison commonly applied in the environmental and agricultural economics literature consists of a control group of buyers who are asked to hypothetically choose between conventional and organic beans and an experimental group of buyers who are endowed to purchase the same beans using an identical experimental design. Hypothetical bias is tested by comparing inter‐ and intra‐respondents’ (i) hypothetical and real choices, (ii) preference parameters of the estimated choice models related to hypothetical and real choices, and (iii) hypothetical and real willingness to pay (WTP). Choices in the experimental group are highly consistent when switching from hypothetical to real choices for this study's homegrown goods. However, after being endowed, the price sensitivity of lower income households drops, suggesting a house money effect. WTP derived from actual purchases is higher than WTP based on hypothetical choices, indicating a negative hypothetical bias, but differences are only significant in the case of the inter‐respondent comparison. Actual prices paid by respondents in the field experiment appear to be considerably lower than the estimated WTP values and yield a mixed picture of hypothetical bias.
Global–Local Incompatibility: The Misperception of Reliability in Judgment Regarding Global Variables
Authors: Broomell Stephen B. 
Published: March 2020

AbstractA number of important decision domains, including decisions about hiring, global warming, and weather hazards, are characterized by a global–local incompatibility. These domains involve variables that cannot be observed by a single decision maker (DM) and require the integration of observations from locally available information cues. This paper presents a new bifocal lens model that describes how the structure of the environment can lead to a unique form of overconfidence when generalizing the reliability of the local environment to a global scale. When the local environment does not reliably reflect the global environment, they are incompatible. While local perspectives vary across DMs, global–local incompatibility can be understood using the structure of classical test theory as the difference between (a) perceived estimates of the reliability derived from the local environment and (b) the true reliability of the local environment. I model global–local incompatibility as the difference between the true and estimated reliability when the assumptions of classical test theory are violated. Using a series of case studies and an empirical study, I demonstrate the widespread utility of this framework, and I conclude by discussing implications for cognitive–ecological theory, risk communication, and overconfidence.
