Population genetic structure of the maize weevil, Sitophilus zeamais, in southern Mexico
Authors: Baltzegar Jennifer , Jones Michael S. , Willcox Martha , Ramsey Janine M. , Gould Fred 
Published: February 2022

AbstractThe maize weevil, Sitophilus zeamais, is a ubiquitous pest of maize and other cereal crops worldwide and remains a threat to food security in subsistence communities. Few population genetic studies have been conducted on the maize weevil, but those that exist have shown that there is very little genetic differentiation between geographically dispersed populations and that it is likely the species has experienced a recent range expansion within the last few hundred years. While the previous studies found little genetic structure, they relied primarily on mitochondrial and nuclear microsatellite markers for their analyses. It is possible that more fine-scaled population genetic structure exists due to local population dynamics, the biological limits of natural species dispersal, and the isolated nature of subsistence farming communities. In contrast to previous studies, here, we utilized genome-wide single nucleotide polymorphism data to evaluate the genetic population structure of the maize weevil from the southern and coastal Mexican states of Oaxaca and Chiapas. Our study is the first to find significant genetic population structure in the maize weevil. Here, we show that although there continues to be gene flow between populations of maize weevil, that fine-scale genetic structure exists. It is possible that this structure is shaped by the movement and trade of maize by humans in the region, by geographic barriers to gene flow, or a combination of factors.

Authors: Lin Tao , Li Yaning , Zhao Rongjin , Ma Zekun , Xie Jianan 
Published: February 2022

Purpose
This paper aims to improve the device performance from the perspective of reducing ohmic contact resistance; the effects of different electrode structures and alloying parameters on the series resistance and power-current-voltage of laser diodes (LDs) have been investigated in this paper.

Design/methodology/approach
Four groups of p-GaAs side metal electrodes with different metal layer arrangements and thicknesses are fabricated for the investigated LDs. The investigated p-GaAs side electrodes are based on Ti/Pt/Au material and the n-GaAs side metal electrodes all have a same structure of Ni/Ge/Ni/Au/Ti/Pt/Au. The LDs with different electrodes were alloyed at 380°C for 60 s and 420°C for 80 s.

Findings
The experimental results show that the series resistance decreases by 14%–20%, the output power increases by 2%–2.2% and the conversion efficiency increases by 1.69%–2.16% for the LDs prepared with optimized alloying parameters (420°C for 80 s). The laser diode with p-GaAs side Ti/Pt/Au electrode of 30/70/100 nm has the best device characteristics under both annealing conditions.

Originality/value
The utilization of this improvement on ohmic contact property in electrode is not only very important for upgrading high-power LDs but also helpful for GaAs-based microelectronic devices such as HBT and monolithic microwave integrated circuit.

PurposeThis study aims to investigate the factors that influence the sustainable online purchase intentions of consumers during the COVID-19 pandemic. This study also examines the role of relational benefit and site commitment in the study model.Design/methodology/approachData were obtained from a survey of 356 Bangladeshi consumers who were voluntarily using the internet during the COVID-19 pandemic. Data were analyzed using partial least square structural equation modelling with Smart PLS 3.0 and SPSS V25 tools.FindingsThe results show a positive and significant relationship between consumers’ personal innovativeness and impulse purchase orientation with their relational benefit and site commitment, social influence with relational benefit, relational benefit with site commitment, site commitment with the intention to purchase. Moreover, the study found that relational benefit mediates the relationship between impulse purchase orientation and social influence with site commitment. The results also indicate that site commitment mediates the relationship between personal innovativeness and impulse purchase orientation with the intention to purchase. The results further indicate that site commitment mediates the relationship between relational benefit and intention to purchase.Practical implicationsThe findings allow online stores to consider crucial factors in their policies when making strategic decisions regarding the factors impacting consumers’ online purchasing intention during the COVID-19 pandemic.Originality/valueIn this study, a research framework is developed with a focus on the sustainable consumer intention to purchase. This study, therefore, adds to the existing literature by analyzing the factors that determine online purchase intentions during the COVID-19 pandemic in Bangladesh, given the limited number of studies on the online consumer behavioral intentions in related circumstances to COVID-19.

Authors: Aslam Ayman , Rana Irfan Ahmad , Bhatti Saad Saleem 
Published: February 2022

Purpose
Urban built-up has been increasing exponentially in the world. Urban population growth and migration are depleting the land resources and creating thermal discomfort. Cities all around the world are facing urban heat island effects and increased temperatures. This study aims to map land cover and formulate local climate zones for enhancing urban resilience against disaster and climate risks.

Design/methodology/approach
This study uses exploratory research to identify local climate zones for Lahore, Pakistan. Landsat 8 imagery was used to develop a land use land cover map. For mapping local climate zones, the standard World Urban and Access Portal Tool procedure was used.

Findings
Results have revealed that Lahore has grown exponentially. Compact low rise and open low rise were the two most common local climate zones prevalent in the city. In contrast, the outer regions of the city consisted of LCZ D (low plants) and LCZ F (bare soil).

Practical implications
This study highlights the need to consider local climate zones in future development plans and policies for ensuring sustainable, resilient and climate-friendly cities.

Originality/value
Local climate zone studies are missing in Pakistan. This study has empirically analyzed the ground situation of local climate zones for Lahore metropolitan city. This study will provide baseline support for future studies on urban heat island and climate change adaptation planning.
How boundary spanners'guanximatters: managing supply chain dependence in China
Authors: Shou Zhigang , Gong Yu , Zhang Qiyuan 
Published: February 2022

PurposeInterorganizational dependence is considered as a liability for each firm and needs to be managed properly. Rather than exploring the opportunistic outcome of dependence, the authors focus on the moderating role of supply chain boundary spanners'guanxi. This study tends to uncover the way and the conditions under which boundary spanners'guanxiinfluences dependence-opportunism relationships.Design/methodology/approachUsing a survey of 380 buyer–supplier exchanges in China, this study first examines the relationship between dependence and opportunism, then assesses the contingent role of boundary spanners'guanxiand further tests how unfairness perception and legal inefficiency alter the role ofguanxiin managing dependence.FindingsThis study finds that buyer dependence increases supplier opportunism while supplier dependence lowers supplier opportunism. Boundary spanners'guanxiweakens the opportunism-facilitating impact of buyer dependence and mitigates the opportunism-restricting effect of supplier dependence. However, unfairness perception would attenuate the value ofguanxiin restricting depended sides' opportunism but strengthen the value ofguanxiin motivating depending sides' opportunism; legal inefficiency would amplify the value ofguanxiin facilitating depending suppliers' opportunism.Originality/valueFirst, the study enriches supply chain dependence studies by incorporating interpersonalguanxiinto the investigation of dependence-opportunism relationships. Second, the study adds to the supply chain management literature by uncovering a contrasting role ofguanxiin influencing the dependence-opportunism relationship. Third, the study incorporates an agency view to uncover two boundary conditions under whichguanxiis mobilized for personal interest seeking or for organizational purposes.
Factors associated with family involvement in a family-centered care program among incarcerated French adolescents with conduct disorder
Authors: Bourion-Bédès Stéphanie , Bisch Michael , Baumann Cedric 
Published: February 2022

Purpose
This study aims to identify the patient characteristics that may influence family involvement in a family-centered care program during detention.

Design/methodology/approach
Little is known about the needs of incarcerated adolescents and their families. This exploratory study used a cross-sectional design to collect data from incarcerated adolescents with conduct disorder followed in a French outpatient psychiatric department. Logistic regression models were used to identify the sociodemographic, clinical and family characteristics of these incarcerated adolescents that could predict family involvement in their care.

Findings
Among 44 adolescents with conduct disorder, the probability of family involvement during the adolescent’s detention was 9.6 times greater (95% CI 1.2–14.4, p = 0.03) for adolescents with no than for those with cannabis substance use disorder, and family involvement decreased with the age of the adolescent (OR = 0.22, 95% CI 0.1–0.9, p = 0.04).

Research limitations/implications
Increased knowledge of the characteristics of these adolescents and their families is needed to develop programs that will increase family interventions by specialty treatment services during detention.

Originality/value
No study has yet been published on French incarcerated adolescents with conduct disorder. As conduct disorder is one of the most important mental health disorders among delinquent adolescents, this study provides knowledge about these adolescents and the need to involve their parents in their care to prevent the further escalation of problem behaviors.
The changing roles of internal auditors in the Ukrainian central government
Authors: Volodina Tamara , Grossi Giuseppe , Vakulenko Veronika 
Published: February 2022

Purpose
The purpose of this paper is to explore how internal auditors’ (IAs) roles have changed because of the diffusion of neoliberal ideologies in the Ukrainian public sector.

Design/methodology/approach
A qualitative methodological approach was applied. Data were collected from 29 semi-structured interviews with public sector auditors in Ukraine’s central government; secondary data analysis was also performed.

Findings
IAs’ role in Ukraine’s central government has changed significantly, with reforms attempting to move to performance auditing. Consequently, Ukrainian central government IAs appeared in the multi-expectation situation, due to the division of the role senders into two different areas. On one hand, IAs are expected to perform new roles set by the Ministry of Finance of Ukraine, while their traditional role as “watchdogs” is still expected by managers (heads of institutions). Diverging expectations resulted in the role conflict that impedes the change in IAs’ role and performance auditing introduction in the Ukrainian central government. Moreover, we identify factors that motivate IAs to prioritise managers’ expectations, while trying to cope with the existing role conflict in Ukraine’s central government.

Originality/value
This study makes a threefold contribution by enriching the understanding of auditors’ roles, role conflicts that public sector auditors may experience and factors that influence how auditors cope with such conflicts, through the lenses of role theory; exploring the change in roles with the emergence of performance auditing; and shedding light on public sector auditing in the less explored context of a post-Soviet country.

Published: February 2022

PurposeCOVID-19 plunged tourism off the cliff in New Zealand. What did this mean for the country, how did we respond and what is the future?Design/methodology/approachThis is a personal account, reflecting on my thoughts and experiences as Chief Executive of Tourism Industry Aotearoa.FindingsIt is a challenging time to try to predict the future given all the remaining COVID-19-related uncertainties. But there are a number of consistencies that will frame the revival of tourism in New Zealand, when international visitors do return. Government, industry and the community will all look to shape the future of tourism, and it is essential we take a balanced score card approach, building back better with a focus on value. However, we must never forget the customer, who may well have the biggest influence.Research limitations/implicationsNo specific research was completed for this article–it relies on the author's industry experience.Originality/valueWe can only have a successful tourism future in Aotearoa if we deliver a broad range of quality products and services that enable us to meet the promise of an economically, socially, culturally and environmentally sustainable destination. The author’s message is to focus on providing customer value in order to achieve that future. It is simple as that.
Predicting travel intentions using self-disclosure, trust and intimacy: the case of Tinder users during COVID-19
Authors: Munoz Kyrie Eleison 
Published: February 2022

PurposeThis paper determines how travel intentions can be predicted using self-disclosure behaviour, trust and intimacy. This case study focuses on Tinder users who utilised the application's Passport feature which allowed them to travel virtually and interact with other users around the globe amid global travel restrictions.Design/methodology/approachThis quantitative research conveniently sampled 294 Tinder users who used the Passport feature during COVID-19 pandemic lockdowns. Data were analysed using PLS-SEM.FindingsThis study revealed that self-disclosure had a significant influence towards future travel intentions. Findings show that the more users self-disclose, the more their intent to travel increase. Trust and intimacy also had significant relationship on travel intentions while intimacy had a mediating effect between self-disclosure and travel intentions.Practical implicationsTourism-oriented establishments and destination marketers should consider Tinder users as a market segment of future tourists. These users have developed travel intentions through in-app interactions and thus comprise an untapped market of potential tourists seeking for meet-ups and niche experiences in a post-pandemic era.Originality/valueThis study provides novelty in showing the predictive relationship of self-disclosure, trust and intimacy towards travel intentions. A model consisting of these constructs in the context of online interactions was also empirically tested and found adequate to predict travel intentions.

Uncovering the non-linear association between VAIC and the market value and financial performance of firms
Authors: Marzo Giuseppe , Bonnini Stefano 
Published: February 2022

Purpose
This paper aims to address empirical analyses of the association of the VAIC and its components with firms’ market and financial performance, demonstrating that the ill definition of variables and constructs is responsible for a non-linearity concealed in the VAIC formula between two of its components (the Structural Capital Efficiency and the Human Capital Efficiency).

Design/methodology/approach
Through a conceptual analysis the paper identifies and formalises the non-linearity concealed in the VAIC formula and clarifies the relevant issues through an empirical analysis of a sample of Italian listed companies.

Findings
The paper finds that the non-linearity hidden in the VAIC formula should lead scholars to completely revise the ways they test the association of the VAIC and the market and financial performance of the firm. Useful insights are also provided for scholars interested in investigating the role of human capital, for those involved in analysing the interrelations among capitals through the introduction of interaction terms in their regression models and for researchers proposing modified versions of the VAIC. Practitioners could benefit from the paper as the non-linearity here discovered leads to a substantial of the decision-making based on the VAIC.

Originality/value
The paper offers new insights into analyses using the VAIC as it uncovers a non-linearity hidden in the VAIC, which has hitherto not been reported in the literature. The existence of this non-linearity has substantive implications for previous and future research in this domain.
Comparative performance analysis of AES encryption algorithm for various LVCMOS on different FPGAs
Authors: Bisht Neeraj , Pandey Bishwajeet , Budhani Sandeep Kumar 
Published: February 2022

Purpose
Privacy and security of personal data is the prime concern in any communication. Security algorithms play a crucial role in privacy preserving and are used extensively. Therefore, these algorithms need to be effective as well as energy-efficient. Advanced Encryption Standards (AES) is one of the efficient security algorithms. The principal purpose of this research is to design Energy efficient implementation of AES, as it is one of the important aspects for a step toward green computing.

Design/methodology/approach
This paper presents a low voltage complementary metal oxide semiconductor (LVCMOS) based energy efficient architecture for AES encryption algorithm on Field Programmable Gate Array (FPGA) platform. The experiments are performed for five different FPGAs at different input/output standards of LVCMOS. Experiments are performed separately at two frequencies (default and 1.6 GHz).

Findings
The comparative study of total on-chip power consumption for different frequency suggested that LVCMOS12 performed best for all the FPGAs. Also, Kintex-7 Low Voltage was found to be the best performing FPGA. At 1.6 GHz frequency, the authors observed 55% less on-chip power consumption when switched from Artix-7 with LVCMOS33 (maximum power consuming combination) to Kintex-7 Low Voltage with LVCMOS12. Mathematical models are developed for the proposed design.

Originality/value
The green implementation of AES algorithm based on LVCMOS standards has not been explored yet by researchers. The energy efficient implementation of AES will certainly be beneficial for society as it will consume less power and dissipate lesser heat to environment.
Aspiring to include versus implicit ‘othering’: teachers' perceptions of inclusive education in Wales
Authors: Knight Cathryn , Clegg Zoe , Conn Carmel , Hutt Matt , Crick Tom 
Published: February 2022

Wales, one of the four nations of the UK, is currently undergoing major education system‐level reform. From the curriculum, through to a new additional learning needs (ALN) system, there is a renewed focus on inclusive education. Research has shown the importance of teachers' attitudes towards inclusion in creating inclusive learning environments. This research study is based on data from a survey of teachers in Wales (n = 253) exploring their perceptions of inclusive education. Thematic analysis of open‐text responses revealed that while teachers were able to articulate the ‘ideal’ of inclusion, these positive ideals were often caveated by both implicit othering of learners with ALN and by the explicit limitations of behaviour, training, and finance and resources. This article critically evaluates the implications of teacher perceptions of inclusive education in Wales, suggesting that without a change in teacher attitudes, the vision of an inclusive education system may be compromised.
Aquatic food animals in the United States: Status quo and challenges
Authors: Jiang Xingyi , Zhao Yaqi , Tang Chunya , Appelbaum Megan , Rao Qinchun 
Published: February 2022

AbstractThis review summarizes (1) the U.S. status quo for aquatic food animal production and marketing; (2) major food safety and quality issues/concerns for aquatic food animals in the United States, including fish misbranding, finfish/shellfish allergies, pathogens, toxins and harmful residues, microplastics, and genetically engineered salmon; and (3) various U.S. regulations, guidances, and detection methods for the surveillance of fishery products. Overall, fish misbranding is the biggest challenge in the United States due to the relatively low inspection rate. In addition, due to the regulatory differences among countries, illegal animal drugs and/or pesticide residues might also be identified in imported aquatic food animals. Future regulatory and research directions could focus on further strengthening international cooperation, enhancing aquatic food animal inspection, and developing reliable, sensitive, and highly efficient detection methods.
