Adaptive memory red deer algorithm for cross-dock truck scheduling with products time window
Authors: Zhou Binghai , Zong Shi 
Published: March 2021

Purpose
The cross-docking strategy has a significant influence on supply chain and logistics efficiency. This paper aims to investigate the most suitable and efficient way to schedule the transfer of logistics activities and present a meta-heuristic method of the truck scheduling problem in cross-docking logistics. A truck scheduling problem with products time window is investigated with objectives of minimizing the total product transshipment time and earliness and tardiness cost of outbound trucks.

Design/methodology/approach
This research proposed a meta-heuristic method for the truck scheduling problem with products time window. To solve the problem, a lower bound of the problem is built through a novel two-stage Lagrangian relaxation problem and on account of the NP-hard nature of the truck scheduling problem, the novel red deer algorithm with the mechanism of the heuristic oscillating local search algorithm, as well as adaptive memory programming was proposed to overcome the inferior capability of the original red deer algorithm in the aspect of local search and run time.

Findings
Theory analysis and simulation experiments on an industrial case of a cross-docking center with a product’s time window are conducted in this paper. Satisfactory results show that the performance of the red deer algorithm is enhanced due to the mechanism of heuristic oscillating local search algorithm and adaptive memory programming and the proposed method efficiently solves the real-world size case of truck scheduling problems in cross-docking with product time window.

Research limitations/implications
The consideration of products time window has very realistic significance in different logistics applications such as cold-chain logistics and pharmaceutical supply chain. Furthermore, the novel adaptive memory red deer algorithm could be modified and applied to other complex optimization scheduling problems such as scheduling problems considering energy-efficiency or other logistics strategies.

Originality/value
For the first time in the truck scheduling problem with the cross-docking strategy, the product’s time window is considered. Furthermore, a mathematical model with objectives of minimizing the total product transshipment time and earliness and tardiness cost of outbound trucks is developed. To solve the proposed problem, a novel adaptive memory red deer algorithm with the mechanism of heuristic oscillating local search algorithm was proposed to overcome the inferior capability of genetic algorithm in the aspect of local search and run time.

Authors: Khokhotva Olga , Elexpuru-Albizuri Iciar 
Published: March 2021

PurposeThe paper describes two reflective instruments: a reflective diary (RD) and a joint learning protocol (JLP) for teachers' knowledge creation in lesson study (LS), reflects on teachers' reactions and encountered challenges and draws inferences on how teachers' learning and knowledge creation could be facilitated more effectively in LS through “learning keeping.”Design/methodology/approachThis qualitative case study of an action research project utilizes the data collected through the narrative inquiry within an LS initiative with four English as a foreign language (EFL) teachers in a school in Spain.FindingsThe study suggests that the incorporation of reflective writing in LS as a method of keeping records of teachers' individual and collective reflections should be considered “a good practice” and yet another important mechanism facilitating teachers' learning in LS.Research limitations/implicationsThe study is limited by its scope since the applied LS model suggests carrying out three consecutive cycles rather than two.Originality/valueFirstly, the two proposed instruments could be of practical value to educators and facilitators employing LS as an approach to teachers' professional learning. Secondly, the study adds to the discussion on the mechanisms fostering teachers' learning in LS by emphasizing “learning keeping” as a form of record-keeping through reflective writing. Thirdly, the study is set in the new for the LS community context, in the autonomous community of the Basque Country, Spain.

Published: March 2021

Purpose
This study aims to investigate the impact of transformational leadership on the innovation of small and medium enterprises (SMEs) through employee voice behaviors. Drawing from the upper echelon theory, it is hypothesized that employee voice is the mediating mechanism through which transformational leadership affects the process and product innovation in SMEs.

Design/methodology/approach
Data was collected from 169 SMEs of Pakistan through an online self-administered questionnaire. The proposed hypotheses were tested using partial least squares structural equation modeling (PLS-SEM).

Findings
Findings confirm that transformational leadership positively affects both process and product innovation in SMEs and employee voice behavior mediates between these relationships.

Originality/value
This research contributes to both theoretical and practical domains by providing evidence that encouraging employees to raise their voice positively impacts product and process innovation and transformational leadership is a potential organizational factor to shape employee voice and process and product innovation. To the best knowledge, this is the first study that investigates the mediating role of employee voice between transformational leadership and process and product innovation in SMEs and developing country’s context.
Knowledge-sharing mechanisms: human resource practices and trust
Authors: Yu Huajiang , Takahashi Yoshi 
Published: March 2021

PurposeThis study sought to examine the detailed mechanism of employee perceptions of commitment-based human resource practices (CBHRPs) to employee knowledge-sharing behavior (i.e. knowledge collection and knowledge contribution) by unveiling the “black box” of trust in the workplace.Design/methodology/approachBased on data from 383 employees in China's Top Innovators in 2016, path analysis was used to test six hypotheses.FindingsEmployee perceptions of CBHRPs, namely, selection, incentives and training and development, were positively related to employees' trust in coworkers, supervisors and the organization, which in turn was positively related to employees' knowledge collection and contribution behavior. Trust in the workplace fully mediated the relationship between employee perceptions of CBHRPs and employee knowledge sharing. Among CBHRPs, training and development practices had the strongest effects on employees' knowledge-sharing behavior. Among trust, trust in coworkers was found to be the closest related to knowledge-sharing behavior. Knowledge contribution was more related to CBHRPs through trust than knowledge collection was.Practical implicationsOrganizations can employ CBHRPs to enhance trust in the workplace and encourage employees to contribute toward and collect knowledge. Organizations need to pay more attention to employees' long-term investment, such as employee training and development. Organizations can perform human resource practices consistently and ensure that all employees are aware of practices in use to enhance employees' understanding of these practices.Originality/valueThis study provides a detailed understanding of the relationship between human resource management and knowledge sharing. It also presents new empirical evidence in the research fields of human resource management and knowledge management, with implications for the development of employees' knowledge-sharing behavior.

Published: March 2021

PurposePlanning and managing the transportation services for Olympic host cities is a complex task. This paper contributes to the event management literature by presenting empirical evidence of the public transportation issues using a case study of a local community-focused Olympic host city. Key factors underpinning transportation issues outcomes are identified.Design/methodology/approachThe Rio 2016 Olympic city was selected as a case study. To develop a scale of public transportation issues, four stages of scale development were conducted: a construct definition and content domain; item generation and expert review; a quantitative study for the purification of the scale; and a quantitative study to validation of the scale. Data were collected among local citizens who lived in the Olympic host city (n = 513).FindingsThe construct of public transportation issues was assigned to five main categories: planning, infrastructures, information, insecurity and urban mobility. The scale shows internal consistency, reliability, construct validity and nomological validity. Transport issues perceived of Olympic host city tend to increase the negative social impact perceived among local citizens.Originality/valueThis study contributes to the harmful impacts discussion of hosting sport mega-events and introduces the transportation issues that the Local Organizing Committee (LOC) needs to know when hosting the Olympic Games. The scale application for the future Olympic host countries is discussed.

PurposeThis paper aims to design an optimum vertical axis wind turbine (VAWT) and assess its techno-economic performance for wind energy harvesting at high-speed railway in Malaysia.Design/methodology/approachThis project adopted AutoCAD and ANSYS modeling tools to design and optimize the blade of the turbine. The site selected has a railway of 30 km with six stops. The vertical turbines are placed 1 m apart from each other considering the optimum tip speed ratio. The power produced and net present value had been analyzed to evaluate its techno-economic viability.FindingsComputational fluid dynamics (CFD) analysis of National Advisory Committee for Aeronautics (NACA) 0020 blade has been carried out. For a turbine with wind speed of 50 m/s and swept area of 8 m2, the power generated is 245 kW. For eight trains that operate for 19 h/day with an interval of 30 min in nonpeak hours and 15 min in peak hours, total energy generated is 66 MWh/day. The average cost saved by the train stations is RM 16.7 mil/year with battery charging capacity of 12 h/day.Originality/valueWind energy harvesting is not commonly used in Malaysia due to its low wind speed ranging from 1.5 to 4.5 m/s. Conventional wind turbine requires a minimum cut-in wind speed of 11 m/s to overcome the inertia and starts generating power. Hence, this paper proposes an optimum design of VAWT to harvest an unconventional untapped wind sources from railway. The research finding complements the alternate energy harvesting technologies which can serve as reference for countries which experienced similar geographic constraints.

AbstractObjectiveShift work has been proposed to disturb alertness and decrease cognitive efficiency. However, studies so far have had varied findings. The aim of the present study was to compare cognitive function following shifts at different times of the day in an Australian ED context.MethodsA prospective, self‐controlled observational study was conducted on medical and nursing staff at a tertiary referral centre and regional hospital ED. Participants were required to complete the Trail Making Test (TMT), a neurocognitive test consisting of two parts (TMT‐A and TMT‐B), at baseline (at the start of the day) and at the end of their shift (day, evening or night). Related samples Wilcoxon signed‐rank tests were used to compare post‐shift TMT performance to baseline in medical and nursing staff.ResultsOver a 5‐month period, 140 ED staff were recruited including 109 doctors and 31 nurses. After a night shift, medical staff (n = 85) and nursing staff (n = 29) took longer to complete the TMT‐B by 3.4 s (P < 0.001) and 7.1 s (P = 0.01), respectively, compared to baseline. Post‐evening shift, medical staff (n = 59) took longer to complete the TMT‐A by 0.3 s (P = 0.02).ConclusionsNight shift work was associated with a longer TMT time. This may indicate a decrease in cognitive performance, in particular, visual attention, processing speed, task switching and executive function and may implicate the quality of care for patients and worker safety.
“I don't have time for drama”: Managing risk and uncertainty through network avoidance*
Authors: Fader Jamie J. 
Published: March 2021

AbstractThis study employs in‐depth interviews (n = 45) with men 25–34 years in age who live in a Philadelphia neighborhood heavily impacted by mass incarceration. It asks the following: 1) How do they perceive risk? 2) How do they organize their daily routines in response to it? 3) Are there racial differences in perceptions and adaptations to risk? Nearly all of the men of color in the study reported staying in their houses and avoiding public spaces, viewing them as unpredictable and posing an unacceptable level of risk. They worried about “drama” or the potential for interactions with others to lead to attention by the police. Their practice of “network avoidance” often meant a complete lack of engagement in their community. Network avoidance is a racialized adaptation to the expansion of the criminal legal apparatus and the unpredictable nature of men's interactions with its agents and enforcers. It reproduces the effects of incarceration by essentially turning their homes into prisons. Network avoidance effectively erases young men of color from the public sphere in the same way that incarceration removes them from their communities, with considerable costs for the men themselves and for their neighborhoods.
Putting thesystemback into training and firm performance research: A review and research agenda
Authors: Garavan Thomas N. , McCarthy Alma , Lai Yanqing , Clarke Nicholas , Carbery Ronan , Gubbins Claire , Sheehan Maura , Saunders Mark N.K. 
Published: March 2021

AbstractResearch investigating training and firm performance is currently at an inflection point; capable of recognising previous achievements but also having a focus on the future. Based on our review of 207 quantitative papers over a 40‐year period, we find that the field has converged in terms of theory and methods. Important insights have been generated yet there is scope to better understand the complex, interrelated and dynamic nature of the relationship between training and firm performance. We propose that open systems theory (OST) provides the potential to move the field forward and encourage researchers to investigate interactions and linkages between training and performance components, the role of temporal dynamics in inputs and processes, reverse causality and to broaden conceptualisations of firm performance. We consider six principles of OST, highlight productive avenues for future research and identify methodological challenges and implications.
From crafting what you do to building resilience for career commitment in the gig economy
Authors: Wong Sut I , Kost Dominique , Fieseler Christian 
Published: March 2021

AbstractThe present study investigates how individual and collaborative job crafting may help digital labourers to build resilience and career commitment in the gig economy. Results based on a time‐lagged survey from 334 digital labourers indicate that those who engaged in higher individual job crafting reported subsequently higher resilience at the outset. Moreover, high collaborative job crafting compensated for low individual crafting efforts in reaching higher resilience and subsequently higher career commitment in the gig economy. Theoretical and practical implications for sustainable careers in the gig economy are discussed.
Rock phosphate solubilization by abiotic and fungal‐produced oxalic acid: reaction parameters and bioleaching potential
Authors: Mendes Gilberto de Oliveira , Dyer Thomas , Csetenyi Laszlo , Gadd Geoffrey Michael 
Published: March 2021

SummaryOxalic acid‐producing fungi play an important role in biogeochemical transformations of rocks and minerals and possess biotechnological potential for extraction of valuable elements from primary or waste ores and other solid matrices. This research investigates the extraction of phosphate from rock phosphate (RP) by oxalic acid. Reaction parameters were derived using pure oxalic acid solutions to solubilize RP. It was found that the oxalic acid concentration was the main factor driving reaction kinetics. Excess oxalic acid could retard the reaction due to calcium oxalate encrustation on RP surfaces. However, complete P extraction was reached at stoichiometric proportions of apatite and oxalic acid. This reaction reached completion after 168 h, although most of the P (up to 75%) was released in less than 1 h. Most of the Ca released from the apatite formed sparingly soluble calcium oxalate minerals, with a predominance of whewellite over weddellite. Bioleaching of RP employing biomass‐free spent culture filtrates containing oxalic acid (100 mM) produced by Aspergillus niger extracted ~ 74% of the P contained in the RP. These findings contribute to a better understanding of the reaction between apatite and oxalic acid and provide insights for potential applications of this process for biotechnological production of phosphate fertilizer.

AbstractThe Western Land Data Assimilation System (WLDAS) is a custom instance of the NASA Land Information System that combines land surface parameters, meteorological forcing data, and satellite products within a land surface model to produce daily estimates of the water and energy budget variables for the western United States. WLDAS was configured through discussions with partners, with the goal of groundwater sustainability planning for the state of California in mind. The publicly available output dataset has a 1‐km grid resolution and spans 1979–present, which makes it suitable for water resources assessments. The data are also able to contextualize the recent drought events in California. Assimilation of Leaf Area Index, which is demonstrated herein to improve simulation over agricultural areas in California, specifically in terms of evapotranspiration in irrigation regions, will be included along with other data assimilation in subsequent releases of WLDAS.

AbstractBackgroundParity, pregnancy loss, and breastfeeding duration were found to be associated with diabetes. However, the results are inconsistent. Also, no epidemiological studies have examined the association of these reproductive factors with diabetes in the same large population. We aim to investigate the associations between parity, pregnancy loss, breastfeeding duration, and the risk of maternal diabetes in middle‐aged and elderly Chinese females.MethodsWe included 131 174 females aged ≥40 years from the REACTION study (Risk Evaluation of Cancers in Chinese Diabetic Individuals: A Longitudinal Study). Multivariable linear regression and logistic regression were used to assess the association between parity, pregnancy loss, and breastfeeding duration and type 2 diabetes.ResultsThe number of parities and breastfeeding duration were positively related to fasting plasma glucose, 2‐hour postload glucose, glycosylated hemoglobin, and homeostatic model assessment of insulin resistance. Compared with those with one birth, nulliparous women or women with 2 or ≥3 births had a significantly increased risk of diabetes. The odds ratios (OR) and 95% confidence intervals (CI) were 1.27 (1.10‐1.48), 1.17 (1.12‐1.22), and 1.28 (1.21‐1.35), respectively. Compared with women without pregnancy loss, those who underwent 2 (OR 1.09; 95% CI, 1.04‐1.14) or ≥3 pregnancy losses (OR 1.11; 95% CI, 1.04‐1.18) had an increased risk of diabetes. Moreover, women with a breastfeeding duration ≥0 to 6 months (OR 0.82; 95% CI, 0.75‐0.90) and ≥6 to 12 months (OR 0.94; 95% CI, 0.89‐0.99) had a significantly lower risk of diabetes.ConclusionsNulliparous women or women with multiparity or more than one pregnancy loss have an increased risk of diabetes in later life, while women who breastfeed more than 0 to 12 months have a lower risk of diabetes.

AbstractScale insects are hemimetabolous, showing “incomplete” metamorphosis and no true pupal stage. Ericerus pela, commonly known as the white wax scale insect (hereafter, WWS), is a wax‐producing insect found in Asia and Europe. WWS displays dramatic sexual dimorphism, with notably different metamorphic fates in males and females. Males develop into winged adults, while females are neotenic and maintain a nymph‐like appearance, which are flightless and remain stationary. Here, we report the de novo assembly of the WWS genome with a size of 638.30 Mbp (69.68 Mbp for scaffold N50) by PacBio sequencing and Hi‐C. These data allowed us to perform a robust phylogenetic analysis comprising 24,923 gene orthogroups from 16 representative insect genomes. This analysis indicated that holometabola evolved from insects with incomplete metamorphosis in the Late Carboniferous, about 50 million years earlier than previously thought. To study the distinct developmental fates of males and females, we analysed the methylome landscape in either sex. Surprisingly, WWS displayed high methylation levels (4.42% for males) when compared to other insects. We observed differential methylation patterns in males and females for genes involved in steroid and sesquiterpenoid production as well as genes acting in fatty acid metabolism pathways. We measured titre profiles for ecdysone, the principal insect steroid hormone, and juvenile hormone (a sesquiterpenoid) in both males and females, which suggested that these hormones are the primary drivers of sexually dimorphic development. Our results provide a comprehensive genomic and epigenomic resource of scale insects that provide new insights into the evolution of metamorphosis and sexual dimorphism in insects.
