Contributions of entrepreneurial orientation in the use of agile methods in project management
Authors: Garcia Vanessa Mesquita Blas , Martens Cristina Dai Prá , Carvalho Rodrigo Baroni , Martens Mauro Luiz 
Published: March 2021

Purpose
This paper aims to analyze the degree of contribution of the entrepreneurial orientation (EO) of organizations in the use of agile methods (AM) in project management.

Design/methodology/approach
A quantitative approach with the application of a survey with project professionals resulted in 206 valid answers. The data were analyzed using structural equation modeling and the method of partial least squares (PLS).

Findings
The results present empirical evidence of the significant contribution of EO in the use of AM in project management, confirming the main hypothesis of this study. This effect was not influenced by the control variables tested.

Research limitations/implications
This study contributes to the development of research on AM and minimizes the literature gap on the connection between entrepreneurship and AM. The results are limited to the sample. Studies with broader samples and different segments are suggested, as well as the contribution of each dimension of the EO to AM.

Practical implications
Innovativeness, risk-taking, proactiveness, autonomy and competitive aggressiveness (EO dimensions) can contribute to the use of AM and guide actions to develop these behaviors, pursuing better adherence to agile values and the use of AM in project management.

Originality/value
The originality of this study regarding the connection between EO and AM lies on the presentation of a theoretical model of this relationship and reduces the gap in this research field. Given the degree of EO contribution in AM (19.7%), there are other factors that affect the use of AM in project management that should be investigated.
2018 saw a sharp increase in air crash deaths: visualizing and evaluating risk
Authors: Anderson Joe , Williams Susan K. 
Published: March 2021

Theoretical basis
Risk literacy matters for business students. A significant aspect of decision-making is accurately evaluating the risks involved in a decision. Research shows that many people are challenged to understand simple, health-relevant risk rates and probabilities. It also shows that many people are functionally innumerate, even educated people like doctors. While there is much academic work in health aimed at understanding how to communicate health risks to patients, an important personal area for business students, there are many industries and organizations where understanding risk is important for business students’ careers. This case provides opportunities for business students to practice these skills.

Research methodology
This is a secondary-data, compact case. The impetus for the case was a blog and the data gathered is primarily from Aviation Safety Net, Worldbank, Airlines.org, International Air Transport Association and Statista.com.

Case overview/synopsis
Coming across a blog headline, a professor is dismayed at the message: 2018 saw a sharp increase in air crash deaths. Questioning that the headline is appropriate and that the number of fatalities is an appropriate measure, the professor sets out to analyze airline safety data.

Complexity academic level
This case is intended for undergraduate or graduate students in an introductory business analytics course. The focus is on using and communicating risk rates and visualization.
Educator and dairy farmer: the psychological empowerment of entrepreneur V.G. Jayakrishnan
Authors: Shivarajan Sridevi 
Published: March 2021

Theoretical basis
The psychological empowerment theory of intrinsic motivation is the primary theoretical basis for the case. Other theories discussed include personality theories and transformational leadership theory.

Research methodology
This is a field-researched case, based on face to face interviews with V.G. Jayakrishnan. The author also visited Jayakrishnan’s institution and attended an event there. The author also relied upon archival data in the form of newspaper reports: both print and video. The case is based on events before July 31, 2017.

Case overview/synopsis
This case examines how entrepreneur V.G. Jayakrishnan, between 1995–2017, set up two successful, yet distinct businesses, namely, ICD (Institute for Career Development), a leading banking test prepping center in Kerala, India and JK Farms, a state-of-the-art dairy farm. Jayakrishnan’s vision and ability to think far ahead of his competition led to ICD becoming one of the most successful banking test prep centers in Kerala, India. Similarly, Jayakrishnan’s vision of scientific dairy farming allowed him to set up the state of the art JK Farms. The case allows students to examine the concepts of intrinsic motivation and transformational leadership.

Complexity academic level
The case can be used both at the graduate and undergraduate levels. At the graduate level, it can be used at the beginning of any leadership class to foster discussion about intrinsic motivation and transformational leadership. At the undergraduate level, it would be better positioned at the middle of the organizational behavior course after the students have discussed the chapters on motivation, leadership and personality in principal textbooks (Colquitt, LePine and Wesson, McGraw Hill, 2018).

Abstract

As more and more species face anthropogenic threats, understanding the causes of population declines in vulnerable taxa is essential. However, long‐term datasets, ideal to identify lasting or indirect effects on fitness measures such as those caused by environmental factors, are not always available.

Here we use a single year but multi‐population approach on populations with contrasting demographic trends to identify possible drivers and mechanisms of seabird population changes in the north‐east Atlantic, using the Atlantic puffin, a declining species, as a model system.

We combine miniature GPS trackers with camera traps and DNA metabarcoding techniques on four populations across the puffins’ main breeding range to provide the most comprehensive study of the species' foraging ecology to date.

We find that puffins use a dual foraging tactic combining short and long foraging trips in all four populations, but declining populations in southern Iceland and north‐west Norway have much greater foraging ranges, which require more (costly) flight, as well as lower chick‐provisioning frequencies, and a more diverse but likely less energy‐dense diet, than stable populations in northern Iceland and Wales.

Together, our findings suggest that the poor productivity of declining puffin populations in the north‐east Atlantic is driven by breeding adults being forced to forage far from the colony, presumably because of low prey availability near colonies, possibly amplified by intraspecific competition. Our results provide valuable information for the conservation of this and other important North‐Atlantic species and highlight the potential of multi‐population approaches to answer important questions about the ecological drivers of population trends.

Published: March 2021

AbstractMany neurodegenerative diseases are associated with pathological aggregation of proteins in neurons. Autophagy is a natural self‐cannibalization process that can act as a powerful mechanism to remove aged and damaged organelles as well as protein aggregates. It has been shown that promoting autophagy can attenuate or delay neurodegeneration by removing protein aggregates. In this paper, we will review the role of autophagy in Alzheimer's disease (AD), Parkinson's Disease (PD), and Huntington's Disease (HD) and discuss opportunities and challenges of targeting autophagy as a potential therapeutic avenue for treatment of these common neurodegenerative diseases.
Nonprofit Entrepreneurial Orientation in the Context of Cross‐Sector Collaboration
Authors: Al‐Tabbaa Omar , Ciulli Francesca , Kolk Ans 
Published: March 2021

AbstractTriggered by budgetary challenges and growing awareness of social needs, recent years have seen increasing entrepreneurial behaviour in the nonprofit sector, of which collaboration with for‐profit organizations is a case in point. Yet, while extant research has extensively studied the entrepreneurial orientation (EO) of for‐profit organizations, scant attention has been paid to its manifestations in the cross‐sector collaboration context and from the nonprofit perspective, even though numerous nonprofit organizations’ idiosyncrasies point to the need for a reconceptualization of the EO dimensions in that domain. Thus, taking the nonprofit perspective, our research aims to explore the dynamics and nature of EO in the context of nonprofit–business collaboration (NBC), examining how the EO core dimensions manifest themselves when nonprofit organizations (NPOs) proactively engage in NBC. We unpack the meaning of EO through two complementary empirical studies. Our work nuances the rather overlooked entrepreneurial posture of so‐called ‘active‐in‐collaboration’ NPOs, exposes new meanings of collaborative EO dimensions (relational proactiveness, relational innovativeness and relational risk management), discusses their underpinning mechanisms and suggests promising areas for further research and implications for practice.

AbstractBackgroundElectromagnetic navigation bronchoscopy (ENB) is a useful method to obtain tissue for peripheral lung nodules. We aimed to understand the diagnostic yield and safety profile in high‐risk pulmonary nodules that cannot be accessed by percutaneous transthoracic needle biopsy.MethodsIn this single‐center retrospective study, we reviewed patients who underwent ENB for high‐risk pulmonary nodules. All procedures were performed under moderate sedation using intravenous midazolam and fentanyl.ResultsA total of 100 pulmonary nodules in 90 patients were subjected to ENB between October 2018 and May 2020. The median age of the study population was 66 (59–73). The mean diameter of the lung nodules was 27.9 mm. The diagnostic yield of ENB‐guided biopsy was 53.0%. Although the nodule size (odds ratio: 1.055, p = 0.007) and positive bronchus sign (odds ratio: 2.918, p = 0.020) were associated with the diagnostic yield during univariate analysis, nodule size was the only independent variable on the multivariable analysis. Interestingly, the diagnostic yield showed an upward trend after 60 cases, from 45%–65%. Procedure‐related complications were reported in 16 cases; among these, pneumothorax occurred in three cases, and four cases experienced moderate bleeding. No instance of major bleeding or death was linked to ENB‐guided biopsy.ConclusionENB‐guided biopsy for high‐risk pulmonary nodules demonstrated an acceptable diagnostic yield and good safety profile. Moreover, the diagnostic yield was associated with nodule size and procedure experience.

Published: March 2021

AbstractBackgroundPsychiatric and somatic problems in young adulthood have been found to be main drivers of costs in individuals with childhood ADHD. However, knowledge of the patterns of healthcare utilization and costs of comorbidities in middle‐aged adults with newly diagnosed ADHD is very limited.MethodWe studied individuals born 1966–1978 (from the Swedish Total Population Register) with newly diagnosed ADHD between the ages of 30–45 years and individuals without ADHD matched on birthdate, birth county, and sex. Healthcare utilization and expenditure for psychiatric and somatic disorders were obtained over four years (two years pre‐ and post‐initial ADHD diagnosis).ResultsMiddle‐aged adults with newly diagnosed ADHD showed higher levels of healthcare utilization and costs (outpatient, inpatient, medications) for psychiatric and somatic comorbidities relative to adults without ADHD, both before and after the initial diagnosis. Females showed greater average group differences across the study period for medication prescriptions than males. Total incremental annual costs per capita were €2478.76 in adults with ADHD relative to those without, and costs were mainly driven by inpatient care. Psychiatric outpatient visits were statistically significantly higher the year before the ADHD diagnosis compared with two years before and after the diagnosis.ConclusionThis study demonstrates the substantial burden of psychiatric and somatic comorbidities in middle‐aged adults newly diagnosed with ADHD. Psychiatric outpatient visits peaked in the year leading up to the ADHD diagnosis. Findings further suggested that females with ADHD may seek more treatment for comorbidities than males, which may reflect a general female tendency.
Urban Neighbourhood Forums in Ankara as a Commoning Practice
Authors: Ergenç Ceren , Çelik Özlem 
Published: March 2021

AbstractThe neighbourhood forums in Ankara began to convene during the Gezi protests in 2013 and lasted about three years. The activities of Ankara Gezi forums are urban commoning practices in terms of a new set of demands and methods. This paper conceptualises urban commoning practices as method, content, and demand. This framework offers an understanding of urban commoning that is not based on monetary transaction, but focuses on seeing commoning as a social process. Commoning is not ahistorical, rather it is engaged with the historical political potential of urban spaces. Commoning as method discusses organising in commons, commoning as content focuses on the form and meaning of political action, and commoning as demand emphasises the discursive use of right to the city. The case selection of this research enables us to reflect on how urban commoning is experienced in a city under less financial investment pressure, but at the centre of national‐level politics.
Trans‐perineal transection through “Neo‐Anus” for recto‐bulbar urethral fistula using a 5‐mm stapler in laparoscopically assisted anorectoplasty ‐ A novel and secure technique

Published: March 2021

AbstractLaparoscopically assisted anorectoplasty (LAARP) for recto‐bulbar urethral fistula (RBUF) is not now a standard operation due to urethra injury risk and incomplete removal of fistula. Our approach is a novel and secure technique of trans‐perineal transection using a 5‐mm stapler for RBUF. Before performing LAARP, the orifice of RBUF was confirmed under flexible cystoscope inspection. Before transection of RBUF, the center of the muscle complex was detected at perineal skin. The muscle complex and the pubo‐rectal sling were then also confirmed with electrical nerve stimulator under laparoscopic approach. A 5‐mm trocar was inserted to pass through the center of the muscle complex from perineal incision of the neo‐anus. RBUF was stapled and transected using a 5‐mm stapler inserted from the neo‐anus. The operator successfully confirmed complete adequate closure of RBUF under flexible cystoscope inspection. A 5‐mm stapler was effective and useful for the transection of RBUF.

SummaryGlucocorticoid treatment increases venous thromboembolism (VTE) risk. Whether this is due to the medication or the underlying disease, or affects the risk of VTE recurrence, has been difficult to determine. The aim of our present study was to quantify the risk for first and recurrent VTE associated with oral glucocorticoids use, considering the underlying disease. A total of 2547 patients with VTE from the Multiple Environmental and Genetic Assessment of Risk Factors for Venous Thrombosis (MEGA) study were linked to the Dutch Pharmaceutical Statistics register. The risk of first VTE during periods of exposure with oral glucocorticoids was estimated by the self‐controlled case series method and that of recurrent VTE was examined in a cohort design. The incidence rate ratio (IRR) of first VTE in the period of glucocorticoid treatment was 3·51 [95% confidence interval (CI) 2·55–4·80]. This IRR was 2·53 (95% CI 1·10–5·72) in the week before treatment started, 5·28 (95% CI 2·89–9·53) in the first 7 days of treatment, remained elevated afterwards and decreased to 1·55 (95% CI 0·85–3·12) after 6 months, as compared to unexposed periods. The hazard ratio for recurrence was 2·72 (95% CI 1·64–4·78) in treatment periods as compared with no treatment. The increased risk of VTE associated with oral glucocorticoid treatment is due to a combined effect of the treatment and the underlying disease, remaining high during the first months of prescription.
Developmental and Intervention‐Related Change in Autobiographical Memory Specificity in Maltreated Children: Indirect Effects of Maternal Reminiscing
Authors: Valentino Kristin , Speidel Ruth , Lawson Monica 
Published: March 2021

This study examined the development of autobiographical memory specificity (AMS) in a longitudinal randomized controlled trial of 242 maltreated and nonmaltreated children (aged 36–86 months; 50.4% male; 39.7% Black, 25.9% White, 34.5% Latinx/other) and their mothers. Half of the maltreated families were randomized to receive an intervention to improve maternal reminiscing. The effects of maltreatment and the intervention on children’s AMS via two indices of maternal reminiscing, sensitive guidance, and elaboration, were evaluated. Bidirectional associations between AMS and child maladjustment were also examined. Intervention‐related improvement in maternal sensitive guidance 6‐month postintervention (b* = .36) related to greater AMS among maltreated children 1 year later (b* = .19). These findings underscore the role of maternal sensitive guidance in facilitating AMS.

Published: March 2021

SummaryThe weight loss history and weight loss goals were examined in 4108 patients referred to a publicly funded evidence‐based clinical weight management program using a retrospective chart review. The majority of patients were white females, aged of 50.1 ± 13.7 years and a BMI of 39.0 ± 7.5 kg/m2. Pregnancy was the most common reason for weight gain in women (17.7%) and while the reasons in men are more varied (injury, stress and medication: all ~5%). Over 50% of patients cited no specific reason for their weight gain. Self‐directed diet and exercise were the most commonly used self‐reported weight loss methods. Women were more likely to report using medication and bariatric surgical weight loss methods than men (P < .05), and only 5% of women and 12.8% men report never having tried to lose weight in the past. Patients had an ideal weight loss goal of 28.9% to 34.4%, which was similar to the patient's lowest reported adult weight. Approximately 70% of patients enrolling at the clinic had previously lost at least 4.5 kg (10 lb) one or more times and 16.7% lost weight at least 5 times in their life, but patient weight at enrolment was similar to their highest adult reported weight. Thus, most patients referred to this clinical weight management program have previously attempted self‐directed diet and exercise weight loss. Patients were close to their highest adult weight and had very large weight loss goals, similar to what is typically achieved only by surgical intervention, despite having already had several bouts of weight loss.
Using culturomics and social media data to characterize wildlife consumption
Authors: Li Juan , Hu Qi 
Published: March 2021

AbstractWildlife provides food, medicine, clothing, and other necessities for humans, but overexploitation can disrupt the sustainability of wildlife resources and severely threaten global biodiversity. Understanding the characteristics of consumer behavior is helpful for wildlife managers and policy makers, but the traditional survey methods are laborious and time‐consuming. In contrast, culturomics may more efficiently identify the features of wildlife consumption. As a case study of the culturomics approach, we examined tiger bone wine consumption in China based on social media and Baidu search engine data. Tiger bone wine is one of the most purchased tiger products; its consumption is closely related to tiger poaching, which greatly threatens wild tiger survival. We searched a popular social media website for the term “tiger bone wine” and focused on posts that were originally created from 1 January 2012 to 31 December 2018. We filtered and classified posts related to the purchase, sale, or consumption of tiger bone wine and extracted information on providers, consumption motivations, year of production, and place of origin of the tiger bone wines based on the texts and photos of these posts. We found 756 posts related to tiger bone wine consumption, 113 of which mentioned providers of tiger bone wine, including friends (53%), elder relatives (37%), peer relatives (7%), and others (3%). Out of the 756 posts, 266 indicated the motivations of tiger bone wine consumption. Tiger bone wines were consumed as a tonic (34%), medicine (23%), game product (30%), and a symbol of wealth (28%). Some posts indicated ≥2 consumption motivations. These findings were consistent with the search queries from Baidu index. Such information could help develop targeted strategies for tiger conservation. The culturomics approach illustrated by our study is a rapid and cost‐efficient way to characterize wildlife consumption.
