Predictors of perceived success in quitting smoking by vaping: A machine learning approach

Prior research has suggested that a set of unique characteristics may be associated with adult cigarette smokers who are able to quit smoking using e-cigarettes (vaping). In this cross-sectional study, we aimed to identify and rank the importance of these characteristics using machine learning. During July and August 2019, an online survey was administered to a convenience sample of 889 adult smokers (age ≥ 20) in Ontario, Canada who tried vaping to quit smoking in the past 12 months. Fifty-one person-level characteristics, including a Vaping Experiences Score, were assessed in a gradient boosting machine model to classify the status of perceived success in vaping-assisted smoking cessation. This model was trained using cross-validation and tested using the receiver operating characteristic (ROC) curve. The top five most important predictors were identified using a score between 0% and 100% that represented the relative importance of each variable in model training. About 20% of participants (N = 174, 19.6%) reported success in vaping-assisted smoking cessation. The model achieved relatively high performance with an area under the ROC curve of 0.865 and classification accuracy of 0.831 (95% CI [confidence interval] 0.780 to 0.874). The top five most important predictors of perceived success in vaping-assisted smoking cessation were more positive experiences measured by the Vaping Experiences Score (100%), less previously failed quit attempts by vaping (39.0%), younger age (21.9%), having vaped 100 times (16.8%), and vaping shortly after waking up (15.8%). Our findings provide strong statistical evidence that shows better vaping experiences are associated with greater perceived success in smoking cessation by vaping. Furthermore, our study confirmed the strength of machine learning techniques in vaping-related outcomes research based on observational data.

Impact of effective governance structure on succession process in the family business: exploring the mediating role of management succession planning

PurposeThe aim of this research is to analyze empirical evidence of the effect of governance structure (GS) on perceived success of the succession process. It is also reported that in India, family firms have a more informal organization structure and governance and have an informal and unplanned approach to bringing the successors into family business. Previous studies have reported that GS is an important factor for a successful succession process. This study examines the role of management succession planning as an intervening variable to achieve perceived success of the succession process.Design/methodology/approachData have been collected using a questionnaire schedule with 113 respondents who are successors from family business firms in Kerala, India. The study uses snowball sampling technique. Partial least square-structural equation modeling has been used to do data analysis.FindingsThe results of the study showed that GS has a significant positive effect on the success of the succession process. GS has a significant positive effect on management succession planning. Management succession planning partially mediates the relationship between GS and perceived success of the succession process.Research limitations/implicationsThe results of the study indicate the effect of GS on the relationship between, perceived success of the succession process and management succession planning. The mediating role of management succession planning in the above relationship is also confirmed. Therefore, before starting the succession process a good GS should be put in place for ensuring the success of the succession process. Family firms must implement the succession plan well to make the succession process successful.Originality/valueThe main contribution of the study is to empirically investigate the effect of GS and management succession planning to enhance the success of the succession process.

Lessons in Atrocity Prevention: A Closer Look at Guinea

This article identifies the most significant atrocity risk factors and their indicators in accordance with the UN Framework of Analysis for Atrocity Crimes and provides a taxonomy of measures, taken by a variety of external and internal stakeholders, in different combinations, which reduced the risk of atrocity crimes reoccurring after the 2009 stadium massacre in Conakry, Guinea. On the 28th of September 2009, 157 protesters were killed, at least 1200 were injured, and over 100 women were raped by security forces in a stadium in Conakry. The UN’s Commission of Inquiry (coi) concluded that these crimes committed by the security forces amounted to crimes against humanity. The efforts to halt further violence and prevent the commission of crimes post-2009 stadium massacre were varied and encompassed regional and international preventive diplomacy. The coordination of a coherent political strategy among international, regional and sub-regional actors in the Guinean context contributed towards the perceived success in preventing further atrocities in Guinea, post-2009 massacre. Importantly, Guinea is not a typical example in terms of atrocity and conflict prevention, due to a unique regional and global dynamics that allowed for a rapid and rather coherent response to the September 2009 stadium massacre.

Success Talk: Narrative Accounts of Organizational Change

Based on evidence from narrative accounts of organizational change, the potential of dialogic approaches that privilege joint construction of both change challenges and interventions appears very promising. This evidence also demystifies the notion of “well-planned” change, may further strengthen moves away from n-step programmatic approaches to change intervention, reminds readers of the importance of procedural fairness, and invites further research in terms of collective leadership. Where retrospective stories through which participants distinguished perceived success and failure provide the data for analysis, it is important that findings are understood within a narrative rather than an objective frame of reference.

Physical Activity and Healthy Eating Programming in Schools to Support Student’s Health-Related Fitness: An Observational Study

Centers for Disease Control (CDC) guidelines recommend schools use a coordinated health approach to support healthy eating and physical activity. This study examines whether the number of healthy eating and physical activity programs and activities used by schools and their perceived success relate to students’ health-related fitness. This observational study used data from the Healthy Zone Schools Program. Data (collected in 2017–2019) were integrated from three sources: (1) school surveys, (2) FitnessGram®, and (3) the Texas Education Agency. Independent variables were the number of health promotion programs and activities and their perceived success; dependent variables were meeting Healthy Fitness Zone Standards (HFZ) for aerobic capacity and body mass index (BMI). We used mixed-effects logistic regression models. Fifty-six schools were in the analytic sample (n = 15,096 students with aerobic capacity data and n = 19,969 with BMI data). Results indicated the perceived success of physical activity programs/activities was significantly associated with students meeting HFZ standards for aerobic capacity (OR = 1.32, CI = 1.06–1.63). There was a significant direct association between the number of physical activity and healthy eating activities implemented (OR = 1.04, CI = 1.01–1.06) and students meeting HFZ for BMI. Schools using multiple health programs and activities need to balance the number provided with their capacity to maintain success.

To strike or not to strike? an investigation of the determinants of strike participation at the Fridays for Future climate strikes in Switzerland

The Fridays for Future strikes involve students striking for increased action on climate change, and this movement has spread to 185 countries and received widespread media attention. This exploratory study investigates motives for participating or not in the climate strikes and future participation among students in Switzerland. In a sample of N = 638 university students, we found that trust in climate scientists, low trust in governments, response efficacy, protest enjoyment and the perceived success of the strikes predicted participation. Contrary to statements in the public media but consistent with the literature, students who participated in the climate strikes reported consuming less meat, flying less and taking more steps to compensate the CO2 emissions from flights compared to students who did not participate. We discuss how the insights from this study help reveal the determinants of youth collective action on climate change.

Causes of Language Anxiety in an ESL Classroom: Towards a Mentally Healthier Learning Environment

In a typical English language classroom, learners are expected to produce written sentences that are grammatically correct, and they are expected to sound native-like in their pronunciation. However, such expectations may cause anxiety and could potentially hinder the success of creating functional and successful language learners. This study aimed to understand undergraduate students’ language learning anxiety and their perceived success in an ESL classroom in the hopes of creating a mentally healthier language learning environment. Through a quantitative approach, the results of the questionnaire showed that reasons that led to undergraduate students’ anxiety in an ESL classroom were fear of tests, fear of comprehension, and fear of negative evaluation by peers. The results also showed that undergraduate students felt less anxious when lecturers provided non-threatening or mentally healthier environment for students to learn in their classroom. It can be concluded that a lecturer’s teaching styles and strategies affected students’ level of anxiety and can help ensure a mentally healthier language learning environment. From the findings, it is recommended that lecturers create a less formal and friendlier classroom atmosphere by providing psychological support and making students aware of the possible channels to seek help when needed.

Nascent entrepreneur characteristic predictors of early-stage entrepreneurship outcomes

PurposeSocial cognitive theory suggests that entrepreneurs' characteristics affect entrepreneurial outcomes through interaction with their environment. This study examines the relationship between entrepreneurs' characteristics and performance in the context of entrepreneurial nascence.Design/methodology/approachThis study investigated lagged-panel responses from a sample of 100 confirmed nascent entrepreneurs. Data collected on three separate occasions included core self-evaluations, commitment, fear of failure and success. PLS analysis was used to assess mediation of commitment on the self-evaluation – success relationship.FindingsCore self-evaluations are an important predictor of entrepreneurial success in nascent-stage entrepreneurs participating in pre-venture assistance programs; positively affecting success and commitment, while negatively affecting fear of failure.Research limitations/implicationsThis investigation contributes to a fuller understanding of social cognitive theory as it pertains to nascent entrepreneurship. Furthermore, contrary to general expectations found in the entrepreneurship literature, the authors uncover a context where entrepreneurs' characteristics are relevant predictors of early entrepreneurial outcomes.Practical implicationsResults showed core self-evaluations as a robust predictor of perceived success in nascent entrepreneurs. Administrators of pre-venture assistance programs should consider screening applicants to programs designed to assist nascent entrepreneurial opportunity development for signs of high core self-evaluations.Originality/valueThis study advances theory by (1) demonstrating the value of assessing nascent entrepreneurs' core self-evaluations as a specific predictor of early-stage entrepreneurial outcomes, (2) suggesting social interaction amidst participation in pre-venture assistance programs makes commitment a salient part of perceived success and (3) providing evidence that entrepreneur-level characteristics need consideration in the context of nascent entrepreneurship and pre-venture assistance programs.

Metacognition, entrepreneurial profile, and perception of success

This study sought to identify to what extent metacognition has an effect on perceived success, mediated by the entrepreneurial profile. The sample we analyzed involved 194 alumni from Business Administration, Accounting, and Economics programs from public and private higher education institutions in the state of Sergipe. The procedures involved the use of structural equation modeling and the results indicated that goal orientation has a significant direct and indirect relationship with perceived success. Metacognitive knowledge and metacognitive experience have significant indirect relationships with perceived success, and this relationship takes place with the "self-realization" and "leader" dimensions of the entrepreneurial profile. As this study's contribution, we identified metacognitive characteristics that can be improved to enhance the perception of success, such as: frequently defining goals, understanding the relationship between tasks and goals, setting specific goals, frequently evaluating a task's progress, selecting the best option for problem solving, using assertive strategies in the past, gaining prior knowledge regarding a task, breaking problems into small parts, thinking before performing a task, using different strategies, organizing time and information, selecting important information, and using intuition to formulate strategies.
