Mobile learning adoption continuance: role of locus of control on its determinants
Authors: Magsayo Roche Tumlad 
Published: March 2022

Purpose
This study aims to investigate the factors affecting (i.e. determinants) the continuance of mobile learning adoption in an informal setting among higher education learners from a rural region in the Philippines. It assesses the extent of the determinants of mobile learning adoption continuance and their interrelationships and the role of a personality trait (e.g. locus of control) on its determinants.

Design/methodology/approach
This study used a rigorous literature review method that led to a mobile learning adoption continuance model. This proposed model analyzed the perceptions of higher education learners’ experiences on mobile learning adoption during the COVID-19 pandemic (i.e. informal setting). The data collection was self-administered using an online survey from a convenience sample size of 434 using adapted questionnaire instruments. The study used factor analysis by using a structural package for social sciences (SPSS) and analysis of the moment of the structure. The effect sizes of the direct effect, simple and serial mediation and interaction effects in a path model were analyzed by using user-defined estimand and orthogonalized approaches.

Findings
The findings indicate that the effect of perceived security risks along with perceived functional benefit and learner value affect the mobile learning adoption continuance. The perceived learner value mediates the perceived functional benefit relationship on mobile learning adoption continuance. Perceived security risk indirectly affects mobile learning adoption continuance through perceived functional benefit and learner value. In addition to this, the internal locus of control strengthens the positive relationship between perceived functional benefit and mobile learning adoption continuance. However, it dampens the positive relationship of perceived learner value.

Originality/value
The study provides an essential foundation on the mobile learning adoption model that focuses on its continuance. This model integrated perceived security risks, functional benefits and learner value aspects of continuance intention that higher education institutions may consider in their mobile learning initiative. It further provides evidence to intensify the important moderating role of locus of control that intervenes on the determinants of mobile learning adoption continuance.
Choosing the most economically advantageous tender using a multi-criteria decision analysis approach
Authors: Lehtonen Juha-Matti , Virtanen Kai 
Published: March 2022

Purpose
The purpose of this paper is to propose and test a multi-criteria decision analysis (MCDA) approach based on an additive value function (AVF) to select the most economically advantageous tender under European Union public procurement regulations.

Design/methodology/approach
A case study in which the AVF tender evaluation model is constructed by the procurement personnel and the results of the original, real-life public procurement evaluation model are compared to those discovered by the MCDA approach.

Findings
The AVF model captures the preferences of the procurement authority in a more reliable and transparent manner than commonly used evaluation models based on scoring formulas.

Practical implications
While commonly used in public procurement, relative scoring formulas can neither present the preferences of a procurement unit accurately nor do they enable bidders to draft bids according to these preferences. The proposed MCDA approach can achieve both.

Originality/value
The contribution of this paper is threefold. First, the successful construction of the AVF model with procurement personnel is introduced. Second, the model is used in an actual, real-life case. Third, a thoughtful comparison of features, structures and results of the AVF model and the evaluation model using scoring formulas is presented.
Evaluation of a technical information systems module for distance learning during the COVID-19 pandemic
Authors: Aryal Arun , Balan Shilpa 
Published: March 2022

PurposeIn the wake of the pandemic (COVID-19) throughout the United States, many educators had to promptly switch to online modality to continue to provide education to students with safety through physical distancing requirements. This study mainly focuses on delivering an Information Systems module aligned with the information systems curriculum model during a pandemic.Design/methodology/approachThe authors used data collection techniques from student assignments and course tasks. These data are used for the purpose of academic assessment for the Information Systems program. The student performance is assessed on a 5-point scale (1 being low and 5 being high) for the synchronous and the asynchronous tasks related to the course. The authors compared the student performance during the pandemic to the pre-pandemic semester.FindingsThis study revealed that the technical module of an information systems course can be successfully delivered during a pandemic in a remote session. However, the authors found that there is a decline in the student performance in synchronous tasks and asynchronous tasks. But the decline of the student performance in the synchronous tasks is greater than that of the asynchronous tasks. The result of this study helps the Information Systems program with their assessment and to improve their course delivery during a pandemic.Originality/valueIn this paper, the authors examine the delivery of a technical module in the field of information systems via online learning models. The authors particularly examine the synchronous and asynchronous online learning models in the delivery of the technical module. The lessons learned from transitioning to the online modality can help universities better prepare for the future during unprecedented times.
A volatile mind? Experimental evidence on dealers' biases and market volatility
Authors: Roy Trivedi Smita 
Published: March 2022

PurposeThe study tests the hypothesis that following the arrival of news in the forex market, the trader/dealers demonstrate two kinds of biases which makes markets volatile: “Recurrence bias,” the belief that news which formerly led to volatility, will again generate volatility (i.e. volatility is recurring), and “Volatility Perception Bias,” the belief that increased volatility following the arrival of a news would persist.Design/methodology/approachThe author uses a preliminary survey and three simulated trading game experiments involving professional foreign exchange dealers to understand these heuristic-led biases and the biases' impact on market volatility.FindingsThe paper finds evidence supporting the presence of both “Recurrence Bias” and “Volatility Perception Bias” and a statistically significant, positive impact of participant biases' on market heterogeneity.Originality/valueThe paper makes two important contributions: first, the use of simulated trading game experiment involving professional dealers and second, the incorporation of dealers' biases and heuristics in understanding forex volatility.
Genome and proteome analyses show the gaseous alkane degrader Desulfosarcina sp. strain BuS5 as an extreme metabolic specialist

Published: March 2022

SummaryThe metabolic potential of the sulfate‐reducing bacterium Desulfosarcina sp. strain BuS5, currently the only pure culture able to oxidize the volatile alkanes propane and butane without oxygen, was investigated via genomics, proteomics and physiology assays. Complete genome sequencing revealed that strain BuS5 encodes a single alkyl‐succinate synthase, an enzyme which apparently initiates oxidation of both propane and butane. The formed alkyl‐succinates are oxidized to CO2 via beta oxidation and the oxidative Wood–Ljungdahl pathways as shown by proteogenomics analyses. Strain BuS5 conserves energy via the canonical sulfate reduction pathway and electron bifurcation. An ability to utilize long‐chain fatty acids, mannose and oligopeptides, suggested by automated annotation pipelines, was not supported by physiology assays and in‐depth analyses of the corresponding genetic systems. Consistently, comparative genomics revealed a streamlined BuS5 genome with a remarkable paucity of catabolic modules. These results establish strain BuS5 as an exceptional metabolic specialist, able to grow only with propane and butane, for which we propose the name Desulfosarcina aeriophaga BuS5. This highly restrictive lifestyle, most likely the result of habitat‐driven evolutionary gene loss, may provide D. aeriophaga BuS5 a competitive edge in sediments impacted by natural gas seeps.Etymology: Desulfosarcina aeriophaga, aério (Greek): gas; phágos (Greek): eater; D. aeriophaga: a gas eating or gas feeding Desulfosarcina.
DO‐SRS imaging of diet regulated metabolic activities in Drosophila during aging processes

Published: March 2022

AbstractLipid metabolism plays crucial roles during aging processes, but how it is regulated by diets and how it interplays with aging still remain unclear. We proposed a new optical imaging platform by integrating heavy water (D2O) probing with stimulated Raman scattering (DO‐SRS) microscopy, for the first time, to directly visualize and quantify lipid metabolism regulated by different diets and insulin signaling pathway in Drosophila fat body during aging. We found that calorie restriction, low protein diet, and (moderately) high protein and high sucrose diets enhanced lipid turnover in flies at all ages, while (moderately) high fructose and glucose diets only promoted lipid turnover in aged flies. The measured lipid turnover enhancements under diverse diets were due to different mechanisms. High protein diet shortened the lifespan while all other diets extended the lifespan. Downregulating the insulin signaling pathway enhanced lipid turnover, which is likely related to lifespan increase, while upregulating insulin signaling pathway decreased lipid turnover that would shorten the lifespan. Our study offers the first approach to directly visualize spatiotemporal alterations of lipid turnover in aging Drosophila in situ, for a better understanding of the interconnections between lipid metabolism, diets, and aging.
Taking advantage of multiple identities to reduce defensiveness to personally threatening health messages

Published: March 2022

AbstractA host of studies have shown that self‐relevant health messages may result in increased defensiveness and rejection of protective recommendations. Drawing on research showing that multiple identities offer psychological resources to deal with identity threats, we sought to examine whether the salience of an alternative identity before people are exposed to a personally relevant health message may buffer the threat and reduce defensive responses. Two studies were conducted on samples of daily smokers asked to read an antismoking message before completing a range of measures of defensiveness. Half of the participants had an alternative identity made salient beforehand (vs. no salience condition). Consistent with our hypotheses, Study 1 (N = 90) showed that this manipulation significantly reduced defensiveness to the message. Study 2 (N = 95) additionally showed that such effects only occurred when the alternative identity overlapped highly with the threatened identity. The theoretical implications of these findings are discussed.
How to effectively communicate your code of ethics: An empirical study using a cluster randomized control trial experiment
Authors: Gómez‐Alatorre Eugenio , Cuñado Juncal , Ferrero Ignacio 
Published: March 2022

AbstractThis paper proposes a method to measure the effectiveness of an ethics program at one of the most prominent pawnshop chains in Mexico, surveying a sample of 519 workers. This research presents a novel approach to the investigation of business ethics by conducting a cluster randomized control trial experiment to assess effectiveness. No evidence of an enhanced understanding of the existing code of ethics from the communication and explanation of the code was apparent. This could indicate an example of a failed ethics program, suggesting the possibility of additional ineffective ethics programs and companies could be wasting resources on them. We demonstrate that it is possible to implement a cluster randomized control trial, which is considered to be the gold standard in impact evaluation. This should lead to the application of more effective methodologies in the field of business ethics, offering a more comprehensive understanding of the effectiveness of ethics programs.
Quality of governance and corporate real investment: Assessing the impact of foreign aid
Authors: Wen Jun , Farooq Umar , Anagreh Suhaib , Tabash Mosab I. 
Published: March 2022

AbstractDeveloping economies are the main recipients of foreign aid. Nonetheless, such countries must face trade‐offs regarding poor governance due to the inflow of foreign aid because aid hampers governance situations. Given that, the current study aims to examine the role of country governance in defining corporate investment decisions and to ascertain how this effect varies across those countries that receive substantial amounts of foreign aid. To test the hypotheses, we collect the financial information of non‐financial sector enterprises from seven economies and apply the generalized method of moments and two‐stage least square models. The statistical results reveal that governance has a positive influence on corporate investment choices. This positive effect is consistent across individual effects of foreign aid. However, foreign aid systematically deteriorates the governance quality of the host country, referring to donor agencies’ unnecessary interruption of the host country's institutional proceedings. This factor reduces institutional efficiency, which further deteriorates corporate investment. Our empirical analysis suggests that all the countries analysed should focus on better governance situations to promote industrial growth. Policymakers from these economies should ensure the effectiveness of foreign aid and introduce better governance practices to expediate industrial growth.HIGHLIGHTS

Country level governance has a positive and significant impact on CI decisions.

Foreign aid affects CI decisions positively.

Foreign aid deteriorates the host country's governance quality.

The interaction effect of country governance and foreign aid on CI is negative.
Concrete Blocks, Bollards, and Ha‐ha Walls: How Rationales of the Security Industry Shape Our Cities
Authors: Ilum Stine 
Published: March 2022

AbstractSecurity measures take up more and more space in our cities. In parallel, the security industry is growing. To understand these developments, we must take a step back and unfold the rationales and theories that lie behind such security measures and their materiality, specifically in the security industry. This article uses the case of the newly developed counterterrorism industry in Copenhagen to unpack some of the general dynamics that enable growth in the security industry and an increase in security measures. Building on ethnographic fieldwork among security companies, architecture firms, the Municipality of Copenhagen, the national security service, and others, this article shows how theories about counterterrorism develop in an interplay between this diverse group of security actors. The article zooms in on a security company and an architecture firm, and their divergent approaches to counterterrorism measures, and shows how both develop in conflict with local city values and security‐skeptical actors. The two companies work hard to establish and promote theories not only about counterterrorism but also about what is best for the city and its citizens, which help legitimize their work in Copenhagen and shape public opinion on counterterrorism, and, ultimately, the materiality of the city.
Animal agency in wildlife conservation and management
Authors: Edelblutte Émilie , Krithivasan Roopa , Hayek Matthew Nassif 
Published: March 2022

AbstractWildlife conservation and management (WCM) practices have been historically drawn from a wide variety of academic fields, yet practitioners have been slow to engage with emerging conversations about animals as complex beings, whose individuality and sociality influence their relationships with humans. We propose an explicit acknowledgement of wild, nonhuman animals as active participants in WCM. We examined 190 studies of WCM interventions and outcomes to highlight 3 common assumptions that underpin many present approaches to WCM: animal behaviors are rigid and homogeneous; wildlife exhibit idealized wild behavior and prefer pristine habitats; and human–wildlife relationships are of marginal or secondary importance relative to nonhuman interactions. We found that these management interventions insufficiently considered animal learning, decision‐making, individuality, sociality, and relationships with humans and led to unanticipated detrimental outcomes. To address these shortcomings, we synthesized theoretical advances in animal behavioral sciences, animal geographies, and animal legal theory that may help conservation professionals reconceptualize animals and their relationships with humans. Based on advances in these fields, we constructed the concept of animal agency, which we define as the ability of animals to actively influence conservation and management outcomes through their adaptive, context‐specific, and complex behaviors that are predicated on their sentience, individuality, lived experiences, cognition, sociality, and cultures in ways that shape and reshape shared human–wildlife cultures, spaces, and histories. Conservation practices, such as compassionate conservation, convivial conservation, and ecological justice, incorporate facets of animal agency. Animal agency can be incorporated in conservation problem‐solving by assessing the ways in which agency contributes to species’ survival and by encouraging more adaptive and collaborative decision‐making among human and nonhuman stakeholders.
Integration of optimized local directional weber pattern with faster region convolutional neural network for enhanced medical image retrieval and classification
Authors: Mahesh Dhupam Bhanu , Madhuri Bindu , Lakshmi D Rajya 
Published: March 2022

AbstractWith a broad usage of digital imaging data in hospitals, the medical image repository size is growing in a very rapid manner. This creates difficulty in querying and managing these vast databases that in turn leads to the requirement of Content‐Based Medical Image Retrieval (CBMIR) systems. The CBMIR is considered as the major ambiguous and challenging task for reducing the semantic gap among the human queries and images in the datasets having more information content. The main intention of this paper is to enhance medical image retrieval and classification using the improved pattern descriptor and deep learning. For the medical image retrieval, this paper develops the Optimized Local Directional Weber Pattern with a multi‐objective similarity function. This similarity function focuses on the measures like Structural Similarity Index Measure, Peak Signal‐to‐Noise Ratio, Mean Squared Error MSE, and correlation. Likewise, the development of an improved Faster‐Region Convolutional Neural Network (Faster‐RCNN) is adopted in the classification phase. Both the retrieval and classification are enhanced by the Modified Wind Speed‐based Deer Hunting Optimization Algorithm. Considering classification and retrieval tasks, the experiments on benchmark datasets reveal an enhancement from the introduced algorithm when compared over the existing methods.

AbstractBackgroundThere continues to be debate about the lower limit of graft‐to‐recipient weight ratio (GRWR) for living donor liver transplant (LDLT).ObjectivesTo identify the lower limit of GRWR compatible with enhanced recovery after living donor liver transplant and to provide international expert panel recommendations.Data sourcesOvid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central.MethodsSystematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel. Studies assessing how GRWR affects recipient outcomes such as small for size syndrome, other complications, patient and graft survival, and length of stay were included. Protocol registration: CRD42021260794.ResultsTwenty articles were included in the qualitative synthesis, and all were retrospective observational studies. There was heterogeneity in the definition of study cohorts and key outcome measures such as small‐for‐size syndrome. Most studies lacked risk adjustment given limited single‐center sample size. GRWR of ≥ .8% is associated with enhanced recovery. Recipients of grafts with GRWR < .8%, however, were found to have similar outcomes as those with ≥ .8% when appropriate consideration is made for portal flow modulation and recipient illness severity.ConclusionsGRWR ≥ .8% is often compatible with enhanced recovery, but grafts < .8% can be used in selected LDLT recipients with optimal donor‐recipient selection, surgical technique, and perioperative management (Quality of Evidence; Low | Grade of Recommendation; Strong).
Rehabilitation after paediatric acquired brain injury: Longitudinal change in content and effect on recovery
Authors: Forsyth Rob J. , Roberts Liz , Henderson Rob , Wales Lorna 
Published: March 2022

AimTo describe cross‐sectional and longitudinal variation in neurorehabilitation content provided to young people after severe paediatric acquired brain injury (pABI) and to relate this to observed functional recovery.MethodThis was an observational study in a cohort of admissions to a residential neurorehabilitation centre. Recovery was described using the Pediatric Evaluation of Disability – Computer Adaptive Testing instrument. Rehabilitation content was measured using the recently described Paediatric Rehabilitation Ingredients Measure (PRISM) and examined using multidimensional scaling.ResultsThe PRISM reveals wide variation in rehabilitation content between and during admissions primarily reflecting proportions of child active practice, child emotional support, and other management of body structure and function. Rehabilitation content is predicted by pre‐admission recovery, suggesting therapist decisions in designing rehabilitation programmes are shaped by their initial expectations of recovery. However, significant correlations persist between plausibly‐related aspects of delivered therapy and observed post‐admission recovery after adjusting for such effects.InterpretationThe PRISM approach to the analysis of rehabilitation content shows promise in that it demonstrates significant correlations between plausibly‐related aspects of delivered therapy and observed recovery that have been hard to identify with other approaches. However, rigorous, causal analysis will be required to truly understand the contributions of rehabilitation to recovery after pABI.What this paper adds

Rehabilitation content varies widely between, and during, admissions for neurorehabilitation after paediatric acquire brain injury.

Strong correlations are seen between plausibly‐related aspects of rehabilitation content and observed recovery, though careful interpretation is necessary.
