Authors: Li Kaixin , He Ye , Li Kuan , Liu Chengguo 
Published: January 2023

Purpose
With the increasing demands of industrial applications, it is imperative for robots to accomplish good contact-interaction with dynamic environments. Hence, the purpose of this research is to propose an adaptive fractional-order admittance control scheme to realize a robot–environment contact with high accuracy, small overshoot and fast response.

Design/methodology/approach
Fractional calculus is introduced to reconstruct the classical admittance model in this control scheme, which can more accurately describe the complex physical relationship between position and force in the interaction process of the robot–environment. In this control scheme, the pre-PID controller and fuzzy controller are adopted to improve the system force tracking performance in highly dynamic unknown environments, and the fuzzy controller is used to improve the trajectory, transient and steady-state response by adjusting the pre-PID integration gain online. Furthermore, the stability and robustness of this control algorithm are theoretically and experimentally demonstrated.

Findings
The excellent force tracking performance of the proposed control algorithm is verified by constructing highly dynamic unstructured environments through simulations and experiments. In simulations and experiments, the proposed control algorithm shows satisfactory force tracking performance with the advantages of fast response speed, little overshoot and strong robustness.

Practical implications
The control scheme is practical and simple in the actual industrial and medical scenarios, which requires accurate force control by the robot.

Originality/value
A new fractional-order admittance controller is proposed and verified by experiments in this research, which achieves excellent force tracking performance in dynamic unknown environments.

Published: January 2023

Purpose
This study aims to investigate the causal relationships within an experimental culture of improvisation capability and firm performance, following the logic of “culture-capability-performance” and building on informal institution theory and dynamic capability theory.

Design/methodology/approach
Data was mainly collected via on-site questionnaires from firm managers, and 196 valid questionnaires were analyzed using structural equation modeling to test the relationship among experimental culture, improvisation capability and firms’ performance.

Findings
Trust and support had a positive impact on firm spontaneity, while the effect of action promotion and error tolerance was not significant. Action promotion, trust and support demonstrate substantial positive effects on the creativity of a firm. Both dimensions of improvisation capability positively and significantly influence a firm’s performance.

Research limitations/implications
The research respondents were firm managers. Cross-sectional data were used to analyze the model, which may cause common method variance. The research context was limited to China, and the generalizability of the results needs to be considered.

Practical implications
Firms can cultivate a culture of trust and support to enhance their spontaneity and improvisation capability. They can encourage cross-departmental communication, empower employees with autonomy in decision-making, provide appropriate resource support for employees’ decisions and use praise and reward incentives to spur further innovation achievements.

Originality/value
This study addresses the gaps in a firm’s improvisation capability within a Chinese market context by theoretically and empirically examining the role of experimental culture and assessing the relationship among each of the dimensions of improvisation capability in relation to firm performance identified in this study.
TMT transactive memory system and business model design: the moderating effect of strategic orientation
Authors: Chen Yu , Yi Yaqun 
Published: January 2023

Purpose
Top management team (TMT) serves as the critical designer of a firm’s business model, whose cognition exerts key influence on business model design (BMD). Drawing insights from the managerial cognition and knowledge-based views, this paper aims to examine the effect of TMT transactive memory system on BMD and investigate how the relationship between TMT transactive memory system and BMD is contingent upon the firm’s strategic orientation.

Design/methodology/approach
Survey data collected from 210 Chinese firms was used to test the research hypotheses through multivariate regression analysis.

Findings
This paper reveals that TMT transactive memory system facilitates novelty- and efficiency-centered BMD. Furthermore, both differentiation orientation and cost leadership orientation can strengthen the effect of TMT transactive memory system on novelty-centered BMD; the impact of TMT transactive memory system on efficiency-centered BMD is weakened by differentiation orientation but strengthened by cost leadership orientation.

Originality/value
This paper adds to the business model literature by unraveling the effect of TMT transactive memory system on BMD, which not only enriches the internal cognitive antecedents of BMD but also provides an in-depth understanding of how TMTs can use their knowledge structure to proactively design a certain business model. Moreover, this paper also offers insights into how TMTs can better use transactive memory system to design business models according to the specific strategic orientation.
In the classroom I enhance students understanding of entrepreneurship development – the culturo–techno-contextual approach
Authors: Awaah Fred 
Published: January 2023

PurposeThis study aims to present a step-by-step implementation of the culturo–techno-contextual approach (CTCA) in a university classroom to teach industry and competitive analysis in the Ghanaian undergraduate entrepreneurship development curriculum. It further investigates the efficacy of the CTCA in breaking difficulties related to the study of industry and competitive analysis as a difficult concept in the Ghanaian entrepreneurship development curriculum. In doing this, the CTCA is compared with the lecture method.Design/methodology/approachThe study adopts a quantitative approach. A quasi-experimental design is employed to gather data from 215 level 400 (4th-year undergraduate students) entrepreneurship development students at a Ghanaian public university. The experimental group was taught with CTCA, while the control group used the lecture method. The data was collected using the industry and competitive analysis achievement test (ICAAT). As random assignment to experimental and control groups were not possible, the data were subjected to an analysis of covariance approach with pre-test scores added as a covariate.FindingsThe results show that the experimental group significantly outperformed the control group. The results further indicate the efficacy of CTCA in improving undergraduate students’ performance in complex concepts of entrepreneurship.Originality/valueResearchers usually test alternative teaching methods to break down barriers to study difficulties. The study’s uniqueness stems from the CTCA’s ground-breaking application to the study of entrepreneurship development in a Ghanaian public university.
Manufacturing Relocation Ambiguity Model: A Prerequisite for Knowledge Management
Authors: Fjellström Daniella , Hilletofth Per , Fang Tony , Kumar V. , Kumar Ajay , Hua Tan Kim 
Published: January 2023

AbstractKnowledge management and manufacturing relocation have been treated as independent spheres. However, for a relocation to be fruitful, knowledge management needs to be incorporated. The purpose of this research is to shed light on the lack of knowledge management in dynamic manufacturing relocation. In particular, the research focuses on the ability to change, adapt and revert manufacturing relocation decisions, that is, the dynamic nature (or use) of the concept. A Swedish company was used as a case study. Nine in‐depth interviews were conducted with key informants at the company's headquarters in Sweden and its factory in China to capture a dyadic perspective. The findings demonstrate that: (1) knowledge transfer is crucial to create/sustain competitive advantage in the offshoring and reshoring phase; (2) lack of knowledge transfer results in limited learning outcomes with operational and strategic consequences in the relocation; (3) resistance to knowledge transfer in the offshoring creates a knowledge gap that consequently leads to relocation ambiguity in the reshoring phase; and (4) companies need to develop knowledge management strategies to promote knowledge transfer and learn from their international relocation, to cope with relocation ambiguity. Our theoretical contribution introduces the knowledge ambiguity framework, which is a result of insufficient knowledge transfer in the dynamic manufacturing relocation. Even if an organization relocates efficiently, it can fail to take advantage of knowledge transfer and development as potential learning for the organization.
Buildings and Institutional Change: Stepping Stones or Stumbling Blocks?
Authors: Siebert Sabina 
Published: January 2023

AbstractThis study aims to throw some theoretical light on the relationship between institutions and the buildings housing them, particularly in the context of institutional change. Drawing on my ethnographic study of the UK Parliament buildings in London, I put forward a framework for analysing the effects that buildings and the artifacts within them may have on institutional change. This framework consists of three elements: (1) buildings enabling or constraining the activities performed inside; (2) spatial hierarchy; and (3) buildings as a resource. My intention is to draw scholars’ attention to the notion of buildings as sites of contestation – places where conflicts over nature and the extent of institutional change are played out. I conclude that redesigning buildings might be seen as a stepping stone to change, but also that buildings can be used to resist change and maintain the status quo. Although buildings ‘inhabited’ by institutions may appear to stand still, they never do; they change in time, both enabling and constraining those who use them and they have an ability to ‘act back’.
The Impact of Analyst, CEO, and Firm Reputations on Investors in the UK and Japanese Stock Markets
Authors: Hussain Simon , Su Chen 
Published: January 2023

AbstractWe examine the importance of multiple agents’ reputations on the market's reaction to analysts’ stock recommendation revisions (analyst revisions), individually and interactively, in the UK and Japanese stock markets. We find some notable variations in reputation effects between the two markets. In the UK, analyst reputation amplifies the market's reaction to analyst revisions, while in Japan, analyst reputation has no significant impact. Firm reputation diminishes (amplifies) the market's reaction to analyst revisions in the UK (Japan). Only CEO reputation generates similar effects in the UK and Japan, dampening the market's reaction to analyst revisions. We also find that reputations interact in different ways in the two markets. Specifically, firm reputation and CEO reputation tend to moderate the positive effect of analyst reputation in the UK; however, in Japan, CEO reputation tends to moderate the positive effect of firm reputation, but there is no significant interaction effect between analyst reputation and CEO/firm reputation. Our findings are explained using insights both from formal economic models and from various cultural and institutional characteristics.
Assimilating ecological theory with empiricism: Using constrained generalized additive models to enhance survival analyses

Published: January 2023

AbstractIntegrating ecological theory with empirical methods is ubiquitous in ecology using hierarchical Bayesian models. However, there has been little development focused on integration of ecological theory into models for survival analysis. Survival is a fundamental process, linking individual fitness with population dynamics, but incorporating life history strategies to inform survival estimation can be challenging because mortality processes occur at multiple scales.We develop an approach to survival analysis, incorporating model constraints based on a species' life history strategy using functional analytical tools. Specifically, we structurally separate intrinsic patterns of mortality that arise from age‐specific processes (e.g. increasing survival during early life stages due to growth or maturation, versus senescence) from extrinsic mortality patterns that arise over different periods of time (e.g. seasonal temporal shifts). We use shape constrained generalized additive models (CGAMs) to obtain age‐specific hazard functions that incorporate theoretical information based on classical survivorship curves into the age component of the model and capture extrinsic factors in the time component.We compare the performance of our modelling approach to standard survival modelling tools that do not explicitly incorporate species life history strategy in the model structure, using metrics of predictive power, accuracy, efficiency and computation time. We applied these models to two case studies that reflect different functional shapes for the underlying survivorship curves, examining age‐period survival for white‐tailed deerOdocoileus virginianusin Wisconsin, USA and Columbian sharp‐tailed grouseTympanuchus phasianellus columbianusin Colorado, USA.We found that models that included shape constraints for the age effects in the hazard curves using CGAMs outperformed models that did not include explicit functional constraints. We demonstrate a data‐driven and easily extendable approach to survival analysis by showing its utility to obtain hazard rates and survival probabilities, accounting for heterogeneity across ages and over time, for two very different species. We show how integration of ecological theory using constrained generalized additive models, with empirical statistical methods, enhances survival analyses.

Published: January 2023

AbstractBackground and aimsWhereas striatal dopamine D2 receptor (D2R) availability has shown to be altered in individuals with alcohol use disorder (AUD) and in healthy individuals with a family history of AUD, the role of D2R in the development of AUD is unknown. In this positron emission tomography (PET) study, we measured whether D2R availability is associated with subsequent alcohol use and alcohol‐related factors, at a follow‐up 8 to 16 years post‐PET scan, in social drinkers.DesignLongitudinal study investigating the association between PET data and later self‐report measures in healthy individuals.SettingAcademic research imaging centre in Stockholm, Sweden.ParticipantsThere were 71 individuals (68 of whom had evaluable PET data, 5 females, 42.0 years mean age) from a series of previous PET studies.MeasurementsOne PET examination with the D2R antagonist radioligand [11C]raclopride at baseline and self‐report measures assessing alcohol use, drug use, impulsivity, reward sensitivity and family history of alcohol or substance use disorder at follow‐up.FindingsWe found no evidence for an association between D2R availability and later alcohol use (B = −0.019, B 95% CI = −0.043 to −0.006, P = 0.147) nor for the majority of the alcohol‐related factors (B 95% CI = −0.034 to 0.004, P = 0.273–0.288). A negative association with a small effect size was found between D2R availability and later impulsivity (B = −0.017, B 95% CI = −0.034 to −0.001, P = 0.046).ConclusionsLow striatal dopamine D2 receptor availability may not be a strong predictor in the development of alcohol use disorder.

Published: January 2023

AbstractBackground and AimsExcise taxes represent one of the most cost‐effective policies to reduce the harmful use of alcohol. Existing information about their design is limited and no standardized metric has been used to compare tax levels in the Region of the Americas. This study aimed to compare alcohol excise tax policies throughout the Americas, compare tax levels and consider opportunities to improve the impact of excise taxes on alcohol consumption and health.Design and SettingDescriptive analysis using a method developed by the Pan American Health Organization and adapted from the World Health Organization's tobacco tax monitoring. Data were collected by surveying ministries of finance and reviewing tax legislation in effect as of November 2020 in the Region of the Americas.MeasurementsTax policy design indicators, taxes as a percentage of the retail price of the most‐sold brand of beer, wine and spirits, including a weighted average indicator across beverage types, and tax levels per standard drink (10 g ethanol) in international dollars at purchasing power parity.FindingsThirty‐three countries in the Americas (94%) apply excise taxes on alcoholic beverages, with Argentina and Uruguay not applying them to wine. There is significant heterogeneity in excise tax design across countries and beverage types. Only a third of amount‐specific excise taxes are regularly adjusted to avoid erosion. Regional median excise taxes represent the highest share of the price for spirits (21.4%) and the lowest for wine (11.0%). The regional median consumption‐weighted average excise tax share across all beverage types is 12.0%. Excise tax shares are generally higher in Latin America than in the Caribbean and Canada. Excise tax levels per standard drink are generally lower for spirits than for other beverages.ConclusionsAlcohol excise tax policies vary significantly across the Americas, often reflecting national consumption patterns. To maximize their public health impact, tax rates could be increased and tax designs improved, particularly to ensure higher tax burdens on high‐strength drinks.

Published: January 2023

AbstractAimsTo create a novel emergency medical service (EMS) opioid‐related incident (ORI) tiering framework to describe more accurately the opioid epidemic in Massachusetts. By classifying the data, we could more accurately detail differing trends among the new categories.DesignFree‐text fields of Massachusetts EMS reports, from 2013 through 2020, were analyzed to identify ORIs and then categorized into a five‐tier severity cascade based on symptom presentation: ‘dead on arrival,’ ‘acute overdose,’ ‘intoxication,’ ‘withdrawal’ and ‘other ORI.’ As a validation of the new classification, an emergency medical technician, paramedic and emergency medical physician reviewed clinical reports and assigned a severity category to 100 randomly selected cases. The algorithm then assessed the same 100 cases to determine if it could accurately identify the severity category for each case.FindingsValidation of the algorithm by clinical review indicated a substantial level of agreement between the algorithm and the reviewers. Over half of all ORIs were acute overdose (55%), 21% were intoxication, 20% were other ORI, 3% were withdrawal, and 1% were dead on arrival. Overall ORIs decreased in 2020, but the number of ‘dead on arrival’ increased 32% from 2019. Administration of naloxone also differed between the categories, with 95% of acute overdose and 29% of intoxication receiving naloxone.ConclusionsThis novel categorization of emergency medical service opioid‐related incidents in Massachusetts, United States, reveals new trend details and strains on the emergency medical service system. Using these categories also improves dataset linkage within the state and interstate rate comparisons.

Authors: Tohidi‐Esfahani Ibrahim , Trotman Judith 
Published: January 2023

SummaryIbrutinib changed the landscape of treatment in Waldenström macroglobulinaemia (WM) with excellent responses; however, there are high rates of dose reduction due to adverse events. The impact of this reduced dosing is unclear with regards to outcomes. Sarosiek and colleagues provide valuable data in a very large retrospective study demonstrating that dose reduction is effective in managing adverse events in the majority, with equivalent, if not better, outcomes than those without dose reductions.

AbstractBackground and PurposeCannabis legalization has risen in many countries, and its use during pregnancy has increased. The endocannabinoid system is present in the CNS at early stages of embryonic development, and regulates functional brain maturation including areas responsible for respiratory control, data on the influence of external cannabinoids on the development of the respiratory system and possible consequences during postnatal life are limited.Experimental ApproachWe evaluated the effects of prenatal exposure to synthetic cannabinoid (WIN 55,212‐2 [WIN], 0.5 mg·kg−1·day−1) on the respiratory control system in neonatal (P0, P6–7 and P12–13) and juvenile (P27–28) male and female rats.Key ResultsWIN administration to pregnant rats interfered sex‐specifically with breathing regulation of offspring, promoting a greater sensitivity to CO2 at all ages in males (except P6–7) and in juvenile females. An altered hypoxic chemoreflex was observed in P0 (hyperventilation) and P6–7 (hypoventilation) males, which was absent in females. Along with breathing alterations, brainstem analysis showed an increase in the number of catecholaminergic neurons and cannabinoid receptor type 1 (CB1) and changes in tissue respiration in the early males. A reduction in pulmonary compliance was observed in juvenile male rats. Preexposure to WIN enhanced spontaneous apnoea and reduced the number of serotoninergic (5‐HT) neurons in the raphe magnus nucleus of P0 females.Conclusions and ImplicationsThese data demonstrate that excess stimulation of the endocannabinoid system during gestation has prolonged and sex‐specific consequences for the respiratory control system.
