Threshold theorem in isolated quantum dynamics with stochastic control errors
Authors: Okuyama Manaka , Ohki Kentaro , Ohzeki Masayuki 
Published: December 2022

We investigate the effect of stochastic control errors in the time-dependent Hamiltonian on isolated quantum dynamics. The control errors are formulated as time-dependent stochastic noise in the Schrödinger equation. For a class of stochastic control errors, we establish a threshold theorem that provides a sufficient condition to obtain the target state, which should be determined in noiseless isolated quantum dynamics, as a relation between the number of measurements and noise strength. The theorem guarantees that if the sum of the noise strengths is less than the inverse of computational time, the target state can be obtained through a constant-order number of measurements. If the opposite is true, the number of measurements to guarantee obtaining the target state increases exponentially with computational time. Our threshold theorem can be applied to any isolated quantum dynamics such as quantum annealing and adiabatic quantum computation.

Authors: Kamamuta Ayane , Takagi Yuki , Takahashi Mizuki , Kurihara Kana , Shibata Hibiki , Tanaka Kanata , Hata Katsuhiko 
Published: December 2022

AbstractBackgroundPatients recovering from COVID-19 often suffer long-term Long-COVID (e.g., depression, poor concentration, anxiety, sleep disturbances, and fatigue). Similar symptoms also rarely seem to occur after COVID-19 vaccination. There is still no effective treatment for these symptoms. We have had a clinical experience that patients presenting with psychiatric/physical symptoms due to COVID-19 or COVID-19 vaccination (defined as Long-COVID and Post-Vaccine patients) often recover after transcranial magnetic stimulation (TMS) and that TMS poorly heals depression in strongly fatigued patients.Aims1. Determine whether there are differences in background characteristics and symptoms between Long-COVID and Post-Vaccine patients; 2. Examine whether TMS led to an improvement in their symptoms; 3. Test the involvement of fatigue in the recovery of depression of Long-COVID and Post-Vaccine patients with TMS.MethodsWe conducted a retrospective analysis using the medical records of the outpatient clinic of Tokyo TMS Clinic.Results1. We found no differences in initial symptoms and courses of treatment between Long-COVID and Post-Vaccine patients. 2. All psychiatric/physical symptom scores after 10 TMS treatments were significantly better than before. Though these results are of before-and-after studies, numerous reports have suggested that TMS effectively improves depression, insomnia, anxiety, and related neuropsychiatric symptoms, which were also primary complaints of patients in this study. We thus attributed the improvement in QIDS, PHQ9 (Both indices of depression), and GAD7 (anxiety indicator) to TMS. 3. The recovery rate of depression in Long-Covid and Post-Vaccine patients with TMS decreased with the severity of fatigue.ConclusionsThis is the first report to elucidate the efficacy of TMS and the factors affecting it for psychiatric symptoms after COVID-19 and COVID-19 vaccination. Our study may lead to further validation of the effectiveness and mechanisms of TMS in patients suffering from Long-COVID and COVID-19 vaccine long-term adverse reactions.

PVR Limited at a crossroads
Authors: Pant Kanchan , Sahay Arunaditya 
Published: December 2022

Learning outcomes
The case study “PVR Limited at a Crossroads” has been designed with the requirements of strategic management. The learning objectives are as follows:
• Situational analysis – understand the global and Indian media and entertainment industry PESTEL.
• Strategic planning – internal and external environmental analysis – strength, weakness, opportunities and threats (SWOT) analysis helps in achieving the strategic plan.
• Strategy development – to accomplish the turnaround plan, various alternatives are developed; choosing from the possible alternatives is a part of strategic planning.

Case overview/synopsis
PVR Limited (PVR) is the largest premium film exhibition company in India. In their annual report for 2019–2020, Chief Executive Officer Gautam Dutta acknowledged, “It was the first time in our more than two-decade history that we witnessed over 100 million patrons entering our premises in a year”. However, with the onset of Covid-19 pandemic in January 2020, things changed for the entertainment industry in India. There were fears of an eminent third wave and the detection of a new Covid-19 variant, Omicron, added to these fears. Being a major player in the game, PVR felt the impact. And even when the business started to reopen, social distancing remained a concern and ticket sales were impacted. Over-the-top viewership rose dramatically at the cost of the multiplex. The lockdown halted film productions worldwide, leading to a shortage of content. Other revenue streams, such as food and beverage, convenience fees and advertising, also came to a halt. Given the circumstances, Dutta was facing the twin dilemma of how to bring customers back to cinema in a post-pandemic world without in any way compromising the security of its patrons and keeping costs under control while investing in social distancing, safety measures and entertainment infrastructure to enhance the cinematic experience.

Complexity academic level
This case was written for use in Strategic Management classes at the undergraduate and MBA levels. It can be used in both management studies and executive development programs. It is suitable for courses on strategic management and strategic planning focusing on a turnaround strategy. Additionally, the case could be used in consumer behaviour courses in management as the focus of the case is well aligned with discussions related to change in consumer behaviour.

Strategic talent management in hotels during COVID-19: upper echelons and dynamic attention-based perspectives
Authors: Garavan Thomas N. , Sheerin Corina , Koukpaki Serge , O'Brien Fergal , Chami-Malaeb Rola , MacKenzie Cliodhna , Buckley Joan 
Published: December 2022

Purpose
The purpose of this longitudinal study is to qualitatively investigate the role of the general managers (GMs) and senior managers (SMs) in strategic talent management (STM) in hotels during COVID-19. Using upper echelon theory and the dynamic attention-based view, this paper explores the role of upper echelon theory cognitive characteristics (orientation towards STM and decision-making approach) and three dynamic attention-based view attention dimensions (communication, resource attention to the HR function and new configurations of STM) in influencing STM.

Design/methodology/approach
This study uses semi-structured interviews with hotel GMs and SMs at two time points over the duration of COVID-19 in six hotels (family-owned, boutique and international hotel chain) located in Ireland, the UK, Germany, Singapore and India.

Findings
The findings of this study reveal that GMs and SMs across the different hotels differed in their orientation towards STM and their decision-making approaches and this influenced cognitive and resource attention to STM. GMs and SMs remained cognitively attentive to STM through their communications around STM, and they revealed resource attention through resources to the HR function and new configurations of STM practices during COVID-19. The authors identify three distinct configurations of STM practices in operation in hotels during COVID-19.

Practical implications
This study’s findings reveal important practice implications in that GMs and SMs have a key role to play in the implementation of STM and the need to reconfigure how STM is undertaken during the crisis. This contrasts with the more espoused role suggested for these talent actors in the literature.

Originality/value
The authors used a longitudinal qualitative research design to surface the dynamic role of GMs’ and SMs’ cognitive and resource attention to STM in hotels during COVID-19 and the key role that orientation towards STM and decision-making approach affected both cognitive and resource attention dimensions.
Designing lesson study for individual and collective learning: networking theoretical perspectives
Authors: Wake Geoffrey 
Published: December 2022

PurposeThis article aims to explore, by drawing on, and coordinating and combining Cultural Historical Activity Theory and Community of Practice theoretical perspectives, what we might learn about how to design for Lesson Study that best supports both collective and individual learning.Design/methodology/approachThe article primarily makes a theoretical contribution. It does, however, draw on, and is informed by, the design of a large-scale study that sought to improve teaching and learning in mathematics with the particular aim of improving grades of post-16 learners in national examinations in England. Lesson Study was central to the designed intervention and such design is explored from the two theoretical perspectives.FindingsTheoretical analysis suggests how the careful design of Lesson Study can facilitate both individual and collective learning in terms of the theories networked here. In particular, it is suggested that supporting collective learning requires careful attention to how “disturbances” in activity systems need to be designed for rather than being left to chance and how architectures that can support individual learning in terms of identity development should pay attention to supporting emerging practices as well as defining what is non-negotiable.Originality/valueThe article takes a novel approach by coordinating and combining two different, and well established, theoretical approaches, which, significantly, are used quite widely in social science research. Together they provide a rich view of learning at both individual and collective levels and suggest ways in which we might better support design for Lesson Study.
Sustainability practices disclosure of top logistics firms in Australia
Authors: Jadhav Akshay , Rahman Shams , Ahsan Kamrul 
Published: December 2022

PurposeThis study explores the scope, materiality and extent of environmental and social sustainability disclosure – as benchmarked against the Global Reporting Initiatives (GRI-G4) – of the top 10 logistics firms operating in Australia. It also investigates the relationships between the extent of environmental and social sustainability disclosure of these firms and their actual financial performance.Design/methodology/approachThe authors adopted an inductive case study approach for an in-depth investigation of the relationships among concepts. A content analysis of the firms' sustainability reports was performed to determine their pattern and extent of sustainability disclosure against the GRI framework. A disclosure–performance analysis (DPA) matrix was employed to relate the extent of environmental and social sustainability disclosure of these 10 firms with their actual financial performance (i.e. return on assets [ROA] and total revenue growth).FindingsThis study found that the extent of sustainability reporting was relatively high on the labour practices and decent work subgroup, followed by the environmental dimension of the GRI-G4 framework. However, it was relatively low on the society, human rights and product responsibility subgroups of the GRI framework. The DPA revealed that “Leaders” (firms with higher sustainability disclosure levels) achieved significantly higher ROA. However, “Opportunists” (firms with lower sustainability disclosure levels) achieved higher levels of financial returns (i.e. ROA and total revenue growth) with less attention to sustainability issues, which contradicts the win-win view of the sustainability disclosure–financial performance relationship.Originality/valueFirst, this study contributes an in-depth review of sustainability disclosure practices of top logistics firms operating in Australia. Second, using DPA, it identifies the novel effects of environmental and social sustainability disclosure levels on these firms' financial performance. It also sheds further light on the potential effect of investments beyond substantial profitability for sustainability growth and corporate governance on the sustainability disclosure–financial performance relationship.
Asymmetric impact of real effective exchange rate changes on domestic output revisited: evidence from Egypt
Authors: Sharaf Mesbah Fathy , Shahen Abdelhalem Mahmoud 
Published: December 2022

PurposeThis paper investigates the asymmetric impact of the real effective exchange rate (REER) on Egypt's real domestic output from 1960 to 2020.Design/methodology/approachA Nonlinear Autoregressive Distributed Lag (NARDL) model is utilized to isolate real currency depreciations from appreciations and account for the potential asymmetry in the impact of the REER. The analyses account for the various channels via which the REER could affect domestic output.FindingsResults show evidence of a long-run asymmetry in the output effect of REER changes in which only real currency depreciations have a contractionary impact on output, while the REER has no impact on output in the short run.Practical implicationsThe Egyptian monetary authority cannot rely on domestic currency depreciation as a policy instrument to boost domestic output.Originality/valueUnlike most of the previous studies, which assume linearity in the impact of the REER on output, we relax this assumption and hypothesize that the REER changes have an asymmetric effect on the Egyptian domestic output in Egypt. We use a long time span from 1960 to 2020 and control for the potential structural breaks in the REER-output nexus and the various channels through which the REER can affect domestic output.
Evaluating feigning in individuals with intellectual disabilities in criminal cases: a cautionary tale
Authors: Vitacco Michael , Randolph Alynda , Soroko Kaitlyn , Velez Janina , Sigurdsson Diandra 
Published: December 2022

Purpose
Response style evaluation is a fundamental component of forensic examinations. This retrospective study aims to evaluate how measures of feigning performed with individuals with intellectual disabilities (ID) who were undergoing competency to proceed to trial evaluations.

Design/methodology/approach
Using a known-groups design (ID vs non-ID) with 145 individuals, 37 individuals met diagnostic criteria for ID. The individuals were administered the Miller Forensic Assessment of Symptoms Test (M-FAST; Miller, 2001), the Inventory Legal Knowledge (ILK; Musick and Otto, 2010), the Evaluation Competency to Stand Trial-Revised, atypical presentation scale (ATP; Rogers et al., 2004b) and the Competence Assessment for Standing Trial-Mental Retardation (Everington and Luckasson, 1992).

Findings
The total ILK demonstrated differences between groups with a large effect size (Cohen’s d = 1.02). Six items on the ILK had over a 30% difference as a function of group. However, two revised scales from the ILK, the R-ILK-90 and the R-ILK-95 (Rogers et al., 2017), did not demonstrate differences as a function of group membership with small effect sizes (Cohen’s ds = 0.02 and 0.29). The M-FAST total score and ATP scales were not different between groups, although results demonstrated that individuals with ID would be potentially more at risk to for misclassification as feigning on the M-FAST.

Research limitations/implications
This study has several limitations. It is a retrospective study with a relatively small sample size so additional research is needed to substantiate the results. However, this study highlights the potential for individuals with intellectual disabilities to be disadvantaged when undergoing competency to stand trial evaluations.

Practical implications
This manuscript shows that individuals with ID are at-risk for being mislabeled as feigning when employing standard measures of response style testing if appropriate cautions are not used. However, revised measures that take into account baseline information of legal knowledge offer a way forward that may prevent false positives with individuals with ID.

Social implications
The mislabeling of individuals with ID could lead to significant problems, including harsh sentences and unnecessary incarcerations. This manuscript provides real-world data and encourages clinicians to be mindful when evaluation individuals with ID for court-ordered evaluations.

Originality/value
This manuscript is critical, as it shows that caution is needed when using instruments of feigning with individuals with ID who are undergoing competency evaluations. This has value for clinicians who are tasked with completing these evaluations for the courts.
Corporate social responsibility: a review with potential development
Authors: Hazzi Osama , Maldaon Issa 
Published: December 2022

PurposeThis paper aims to review bright sides of corporate social responsibility (CSR) and touches on its dark sides, providing researchers and CSR-driven lay readers with a starting point for further contributions and discussions. The paper also outlines a conceptual perspective about CSR scale development relevant to the uncertain times Syrian Arab Republic is still facing.Design/methodology/approachWith a top ten-journal set indexed in social science citation index (SSCI), the current paper reviewed dozens CSR-references. In different search settings, the paper also included other authoritative references relevant.FindingsCSR, whose bright side is still in the lead, is a significant working philosophy that can keep stakeholders posted on the extent to which organizations can sustain businesses and protect society's welfare at interconnected levels (economic, social, ethical and environmental, among others).Research limitations/implicationsThe review at hand has only covered the tip of the CSR iceberg.Practical implicationsInvesting in CSR transparently could lead to a promising sustainability.Social implicationsWith transparent CSR information, stakeholders (including the public and policymakers) could make an informed decision regarding the extent to which organizations with CSR could protect their well-being.Originality/valueThe current review makes an authoritative reference point new in the CSR literature. In addition, it bridges a research gap not yet studied – by bringing a roadmap outlining a potential CSR-scale development that could cope with the postwar reconstruction phase (an example of which being Syrian Arab Republic).
The “costs of doing business abroad” in a cross-border context characterised by extreme political volatility
Authors: Bjorvatn Torbjørn , Randøy Trond 
Published: December 2022

Purpose
The purpose of this study is to describe and explain the organisation design antecedents of coordination, learning and trust in an international strategic alliance in a cross-border context characterised by extreme political volatility.

Design/methodology/approach
The research was carried out as a single-case study in situ in a humanitarian international strategic alliance in Pyongyang, the Democratic People’s Republic of Korea (North Korea).

Findings
In addition to explaining the effects of interface, specialisation, formalisation and centralisation on coordination, learning and trust, the study demonstrates the influence of classic international business (IB) “costs of doing business abroad” (Hymer, 1960/1976) on the same organisational outcomes. Moreover, the study identifies intergovernmental engagement/containment/disengagement as a contextual antecedent of both organisation design and outcomes.

Originality/value
The study extends IB theory by indicating that mainstream IB perspectives may not fully explain intraorganisational outcomes in cross-border contexts characterised by extreme political volatility. Notably, the study suggests that complementary constructs such as intergovernmental engagement are needed to account for the additional costs incurred by such settings.
Modelling of the multi-jet fusion capillarity effect on close facing edges
Authors: Mele Mattia , Campana Giampaolo , Monti Gian Luca 
Published: December 2022

Purpose
The purpose of this paper is to develop a physical model able to predict the shape of the capillarity effect in multi-jet fusion when two facing edges mutually affect each other. The work also aims at testing the consistency of such a model with experimental observations.

Design/methodology/approach
An analytical model of the phenomenon is developed considering the surface tension of the polymer melt adhering to the unfused powder. The general equilibrium equations are solved by imposing the boundary conditions corresponding to the case of two close facing edges, in which the shapes of the menisci are mutually influenced. The analytical model is validated through an experimental activity. Specifically, a set of parallelepipeds with variable width was manufactured using an HP Multi Jet Fusion 4200. The morphologies of capillarities were captured via three-dimensional scanning and compared with those predicted by the model.

Findings
The results of this study demonstrate that the average error to the experimental capillarity profile is lower than that obtained by existing methods. Particularly, considerable improvements are achieved as far as the maximum capillarity height is concerned. The manufactured specimens exhibit a change in slope near the edges, which is arguably attributable to coating powder and other effects not included in the analytical model.

Originality/value
The model presented in this study differs in hypotheses from previous methods in literature by assuming a null derivative of the capillarity shape in the central point of the meniscus. This allows for a more accurate prediction of the defect morphology in the case of close facing edges.
