Authors: Palma Lisiane Celia , de Oliveira Lessandra Medeiros , Alves Nilo Barcelos , Figueiró Paola Schmitt 
Published: February 2023

Purpose
This study aims to analyze the extent to which sustainability and its related core aspects have been integrated in the curricula of Business Administration programs in Brazilian federal public universities over the past ten years.

Design/methodology/approach
A longitudinal exploratory study, with a descriptive scope, was carried out to evaluate the changes that have occurred in the curricula between the years 2011 and 2021. The analysis focused on the Pedagogical Project of the Business Administration programs offered by the Brazilian federal universities identified in the e-Ministry of Education’s (MEC) database of higher educational institutions and course registration. From the total number of federal universities identified in the e-MEC, about 90% were considered for the research.

Findings
The number of courses related to sustainability in Business Administration programs increased considerably in ten years. However, these courses still represent a low percentage of hours in the overall curriculum. Moreover, almost a third of Business Administration programs may produce graduates who have never addressed sustainability during their studies.

Research limitations/implications
This research does not consider other aspects of the curriculum beyond courses, nor does it collect primary data that allows for inferences about the transversal nature of the theme.

Practical implications
This study contributes to monitoring the performance of Brazilian federal universities teaching sustainability and its related core aspects in Business Administration programs. This updated panorama may aid in the search for strategies to expand actions related to education for sustainability (EfS) in educational institutions (EIs).

Social implications
This study presents some of the impacts of implementing the national environmental education curriculum guidelines. This study encourages discussion about EfS in Business Administration programs and in public EIs, which are important actors for promoting sustainable development.

Originality/value
To the best of the authors’ knowledge, this is the first longitudinal study that maps the courses related to sustainability in Business Administration programs at Brazilian federal public universities. This study offers the first responses to a broad and complex topic, of a region and disciplinary field, of which there are not many studies done, opening doors to subsequent investigations.

Published: February 2023

Purpose
The purpose of this paper is to investigate the impact of the role of trust in leaders in the relationship between dimensions of servant leadership and dimensions of organizational commitment in the information technology (IT) sector of Pakistan in post-COVID era. This paper also highlights the role of trust in leader as mediating mechanism among the examined variables.

Design/methodology/approach
Self-administered questionnaires were distributed to IT professional working in the IT sector of Pakistan. The sample included 283 across Pakistan. Structural equation modeling was used to analyze the data.

Findings
Results indicated that trust in a leader has a significant indirect effect on the relationship between the dimensions of servant leadership and organizational commitment. Upon further investigation, it is found that in the majority of cases, the nature of mediation is partial in nature. Whereas, it is found that trust in leader fully mediates the relationship between persuasive mapping and normative commitment. Furthermore, trust in leader is also found to be fully mediating the relationship between emotional healing and continuance commitment.

Research limitations/implications
This study is limited to the geographical boundaries of Pakistan, results obtained during the course of study have limited generalizability outside the country.

Originality/value
This paper aims at addressing a gap in the literature by developing a model of how trust in leader mediates the relationship between servant leadership and organizational commitment, and examine relationship between individual dimensions of servant leadership and organizational commitment.
Healthcare startups compete in new digital spaces: the lure of virtual specialties
Authors: Jahn Justin , Bohnet-Joschko Sabine 
Published: February 2023

Purpose
This study aims to explore the rise of virtual specialty care startups and understand how the ventures leverage digital services to create a new market space. Given the high level of competition in an established industry like health care, the authors investigate the business models and competitive strategies of leading virtual specialty care startups with unicorn status (i.e. emerging, current and exited unicorns).

Design/methodology/approach
The authors performed an analysis of Crunchbase data to examine whether rising virtual care ventures target specialty care. They focused on companies from the USA, Europe and Asia-Pacific. The identified virtual specialty care ventures were investigated in-depth via a multiple case study. By reviewing corporate websites, Crunchbase data and media coverage, the authors analyzed the ventures’ business models and competitive strategies.

Findings
This study demonstrates that even in established and highly competitive markets such as health care, managers and entrepreneurs can still leverage digital services to unlock new market spaces. The data analysis reveals that virtual care startups target the field of specialty care. They create a new market space by focusing on fast access to services, personalization, measurable outcomes and affordability. The majority of investigated companies pursues a platform-based business model approach.

Originality/value
In the context of an established industry like health care, this study gives insights into a new generation of virtual specialty care ventures. By investigating the ventures’ business models and competitive strategies, the authors advance a young field of research.
Transforming a specialist community service model for working with men with sexual convictions and personality difficulties
Authors: Craissati Jackie , Phillips Ophelia , Higgins Caitriona 
Published: February 2023

Purpose
The purpose of this discussion paper is to describe the transition over the past five years of a highly specialist group treatment programme to a tiered public health delivery model within the offender personality disorder (OPD) pathway. The focus of this journey of transformation has been the Challenge programme, currently the only OPD specialist service for men with sexual convictions in the community in England and Wales, and now a pan-London service.

Design/methodology/approach
More than 600 high-risk men with sexual convictions are screened into the OPD pathway and reside currently in the community across London. The programme leads have developed a triage model – based on the wider OPD model – that applies the principles of the least intervention necessary and the most effective use of limited resources.

Findings
Preliminary informal feedback was sought on the new consultation approach and innovative joint casework delivery models. The model of care is discussed in relation to the preliminary feedback, which was encouraging in terms of satisfaction with the consultation service and in terms of the people on probation who found that participating in the joint casework enhanced their working relationship with offender managers. The consistent use of a single model of care and a careful triage approach across the city to working with this group of individuals is still in development. Early feedback suggests that the service has to potential to be effective, but establishing this requires formal evaluation.

Practical implications
Practice implications include the need to address the lack of confidence that many practitioners report when working with people with sexual convictions. Virtually delivered group consultation may enhance the development of skills as it may providing a flexible toolkit for delivery.

Originality/value
This practice paper describes the only specialist community service for men with high-risk, high-harm sexual convictions and personality difficulties in the UK.
Learning and employee-driven innovation in the public sector – the interplay between employee engagement and organisational conditions
Authors: Lidman Linda , Gustavsson Maria , Fogelberg Eriksson Anna 
Published: February 2023

Purpose
The purpose of this study is to examine learning and employee-driven innovation (EDI) in the public sector, with a particular focus on the interplay between employee engagement and organisational conditions.

Design/methodology/approach
The material consists of qualitative interviews with 23 participants from three municipal sites of innovation support that participated in a national programme aiming to strengthen municipalities’ innovation work.

Findings
The study found numerous constraining organisational conditions resulting in consequential loss of employee engagement for EDI. The conclusion drawn is that employee engagement and enabling organisational conditions are central to EDI in public sector workplaces, and that incorporating EDI into municipal daily operations requires paying attention to the interplay between organisational conditions and employee engagement.

Originality/value
This paper provides important guidance for supporting EDI in the public sector. Implementing EDI into operations requires employee engagement to be successful. However, employees’ engagement should not be overlooked or taken for granted. A practical implication of this study is that EDI in the workplace must be encouraged by creating a learning environment that supports innovative learning in the workplace. In practice, measures should be taken to support employee engagement by creating organisational conditions that provide a more expansive learning environment to ensure the continuity and perpetuation of EDI in public sector organisations.
Effect of improvisational strategic orientation and entrepreneurial bricolage on new venture performance
Authors: Li Xueling , Yu Ting 
Published: February 2023

PurposeThis paper aims to examine the effects of two types of improvisational strategic orientation on new venture performance: defensive improvisation and creative improvisation. Moreover, this study investigates the role of entrepreneurial bricolage in mediating the transition from various types of improvisational strategic orientation to new venture performance.Design/methodology/approachThis study is designed as quantitative research, employing a structural equation model and bootstrap analysis to empirically test the survey data of 249 new ventures gathered to investigate the true relationship between variables in this paper.FindingsThe findings of this study show that (1) both defensive and creative improvisation positively affect the performance of new ventures, with defensive improvisation having a stronger positive effect; (2) both internal and external bricolage positively affect new venture performance, and play varying degrees of intermediary roles in the influence that defensive and creative improvisation has on the performance of start-ups.Research limitations/implicationsThe following limitations apply to this study: First, this paper collects data using a cross-sectional research design, which cannot reveal dynamic changes in the research variables. Second, this study only opens the “black box” of the role of improvisational strategic orientation on new venture performance from the perspective of entrepreneurial bricolage, and the research conclusion may be biased. Finally, the external factors' contingency effect on the relationship between variables is ignored.Originality/valueThis study develops a theoretical research model of improvisational strategic orientation, entrepreneurial bricolage and new venture performance, and provides a thorough examination of the internal mechanisms of various types of improvisational strategic orientation on new venture performance. The research findings not only contribute to the advancement of research on improvisational strategic orientation in the context of entrepreneurship but also assist entrepreneurs in developing a correct understanding of improvisational strategic orientation.

Power quality improvement of large power induction motor drive using three-level front-end converter
Authors: Mohanty Kanungo Barada , Daramukkala Pavankumar 
Published: February 2023

Purpose
The purpose of this study is to provide the enhancement of power quality of a high power-rated voltage source inverter driven induction motor with a three-phase, three-level neutral point clamped converter placed at the front end, while a passive power filter is connected in shunt with it. The improvement in power quality can be achieved by reducing the total harmonic distortion in source current. The controllers were designed for the linearization of the high-power induction motor drive. A control method is presented for the regulation of the common DC-link voltage.

Design/methodology/approach
The induction motor is modeled using its dynamic equations, and a decoupling controller is designed to linearize the nonlinear dynamics of the drive through feedback. The common DC-link voltage of the proposed front-end connected converter is monitored and controlled through a control method which feeds the pulse width modulated inverter that drives the induction motor. A passive power filter is designed to meet the reactive power requirement of the system in addition to improve the power quality.

Findings
Simulations were carried out for the proposed topology of the drive mechanism, and the outcomes were analyzed by a comparative analysis of the drive system both in the presence of the passive filter as well as in the absence of the filter. The total harmonic distortion is found to be reduced enough to meet the standards with the designed filter, and the reactive power is also compensated considerably. The input power factor at the supply side is maintained almost to unity, and the DC-link voltage of the proposed circuit topology is maintained at the desired level. The overall performance of the drive system was found to be useful and economical.

Originality/value
A new topology of a front-end connected three-level neutral point clamped converter to a high power-rated induction motor drive is proposed. The drive is fed by a pulse width modulated inverter with a common DC-link with the front end connected converter. A passive filter is designed with respect to the reactive power requirement of the system and connected in shunt to the converter at the supply side. Control schemes are designed and used for the drive system and also for the regulation of the common DC-link voltage of the proposed front end connected converter.
Single‐amplified genomes reveal most streamlined free‐living marine bacteria

Published: February 2023

AbstractEvolutionary adaptations of prokaryotes to the environment sometimes result in genome reduction. Our knowledge of this phenomenon among free‐living bacteria remains scarce. We address the dynamics and limits of genome reduction by examining one of the most abundant bacteria in the ocean, the SAR86 clade. Despite its abundance, comparative genomics has been limited by the absence of pure cultures and the poor representation in metagenome‐assembled genomes. We co‐assembled multiple previously available single‐amplified genomes to obtain the first complete genomes from members of the four families. All families showed a convergent evolutionary trajectory with characteristic features of streamlined genomes, most pronounced in the TMED112 family. This family has a genome size of ca. 1 Mb and only 1 bp as median intergenic distance, exceeding values found in other abundant microbes such as SAR11, OM43 and Prochlorococcus. This genomic simplification led to a reduction in the biosynthesis of essential molecules, DNA repair‐related genes, and the ability to sense and respond to environmental factors, which could suggest an evolutionary dependence on other co‐occurring microbes for survival (Black Queen hypothesis). Therefore, these reconstructed genomes within the SAR86 clade provide new insights into the limits of genome reduction in free‐living marine bacteria.

Published: February 2023

AbstractObjectiveTo evaluate whether Medicare's Hospital Readmissions Reduction Program (HRRP) is associated with increased observation stay use.Data Sources and Study SettingA nationally representative sample of fee‐for‐service Medicare claims, January 2009–September 2016.Study DesignUsing a difference‐in‐difference (DID) design, we modeled changes in observation stays as a proportion of total hospitalizations, separately comparing the initial (acute myocardial infarction, pneumonia, heart failure) and subsequent (chronic obstructive pulmonary disease) target conditions with a control group of nontarget conditions. Each model used 3 time periods: baseline (15 months before program announcement), an intervening period between announcement and implementation, and a 2‐year post‐implementation period, with specific dates defined by HRRP policies.Data Collection/Extraction MethodsWe derived a 20% random sample of all hospitalizations for beneficiaries continuously enrolled for 12 months before hospitalization (N = 7,162,189).Principal FindingsObservation stays increased similarly for the initial HRRP target and nontarget conditions in the intervening period (0.01% points per month [95% CI −0.01, 0.3]). Post‐implementation, observation stays increased significantly more for target versus nontarget conditions, but the difference is quite small (0.02% points per month [95% CI 0.002, 0.04]). Results for the COPD analysis were statistically insignificant in both policy periods.ConclusionsThe increase in observation stays is likely due to other factors, including audit activity and clinical advances.
Easy to use and validated predictive models to identify beneficiaries experiencing homelessness in Medicaid administrative data
Authors: Pourat Nadereh , Yue Dahai , Chen Xiao , Zhou Weihao , O'Masta Brenna 
Published: February 2023

AbstractObjectiveTo develop easy to use and validated predictive models to identify beneficiaries experiencing homelessness from administrative data.Data SourcesWe pooled enrollment and claims data from enrollees of the California Whole Person Care (WPC) Medicaid demonstration program that coordinated the care of a subset of Medicaid beneficiaries identified as high utilizers in 26 California counties (25 WPC Pilots). We also used public directories of social service and health care facilities.Study DesignUsing WPC Pilot‐reported homelessness status, we trained seven supervised learning algorithms with different specifications to identify beneficiaries experiencing homelessness. The list of predictors included address‐ and claims‐based indicators, demographics, health status, health care utilization, and county‐level homelessness rate. We then assessed model performance using measures of balanced accuracy (BA), sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve (area under the curve [AUC]).Data Collection/Extraction MethodsWe included 93,656 WPC enrollees from 2017 to 2018, 37,441 of whom had a WPC Pilot‐reported homelessness indicator.Principal FindingsThe random forest algorithm with all available indicators had the best performance (87% BA and 0.95 AUC), but a simpler Generalized Linear Model (GLM) also performed well (74% BA and 0.83 AUC). Reducing predictors to the top 20 and top five most important indicators in a GLM model yields only slightly lower performance (86% BA and 0.94 AUC for the top 20 and 86% BA and 0.91 AUC for the top five).ConclusionsLarge samples can be used to accurately predict homelessness in Medicaid administrative data if a validated homelessness indicator for a small subset can be obtained. In the absence of a validated indicator, the likelihood of homelessness can be calculated using county rate of homelessness, address‐ and claim‐based indicators, and beneficiary age using a prediction model presented here. These approaches are needed given the rising prevalence of homelessness and the focus of Medicaid and other payers on addressing homelessness and its outcomes.
Unpredictable and monetized contact with the police: Race, avoidance behaviors, and modified activity spaces
Authors: Giuffre Andrea , Huebner Beth M. 
Published: February 2023

AbstractExponential growth in order maintenance policing and associated misdemeanor sanctions have led to disproportionate consequences for people of color. Using data from qualitative interviews with individuals in the metropolitan St. Louis, Missouri, region, the current study documents the racialized and monetized nature of police contact. This work extends extant scholarship by considering how minor contact with the police shapes individual avoidance behaviors and activity spaces, places where people work and live. We consider how the combination of monetary sanctions, warrants, incarceration, and overpolicing in the region affects avoidance behaviors, particularly for people of color. Our findings suggest that the frequently unpredictable nature of police contacts and the parochial and often profit‐focused structure of policing organizations in the region leads individuals to modify the ways in which they move through the region and, for some, to isolate. Narratives reflect the need for constant calibration of behaviors and decisions, as well as the legacy that police contact and monetary sanctions can have on everyday routines.
