The aviation industry continues to experience landing overruns at general aviation airports due in part to pilots touching down beyond the midpoint of the available runway. In some landing overruns, pilots were unaware that the midpoint was reached and nonetheless continued the landing instead of implementing a go-around/aborted landing procedure. Incident reports confirmed that forced landings were coupled with frequent overruns. Over the years airport operators and pilots have occasionally reported that knowing the location of the midpoint of runways would help them to minimize such accidents. There is a greater tendency for landing overruns at airports that primarily serve general aviation operations with runway lengths less than 4,200 ft in length and being utilized by student pilots and those pilots that primarily fly on the weekends only. In order to identify potential markings that could assist in mitigating this risk, the research team evaluated the design for and potential benefits of a marking placed at or near the midpoint of a general aviation runway that would inform pilots of the potential for an overrun/overshoot on a landing. The research team evaluated several preliminary prototype midpoint runway markings using stakeholder input and an online survey of pilots. The best performing marking was further evaluated in an aviation training device study and in field evaluations at six airports. The study results found that the numeric ½ located to the left of the runway centerline provided pilots with useful information on the remaining length of runway.

Public perceptions on shared mobility has substantially altered human mindsets in current times, gaining widespread popularity, particularly in the context of emerging economies struggling with increasing population density and shrinking infrastructure resources. The purpose of this study is to examine Indian consumers’ readiness towards the adoption of such shared mobility services in metropolitan cities. An online survey questionnaire was implemented to understand consumers’ readiness to adopt, commuting habits, perceived benefits, and challenges while consuming these services. A total of n=257 usable responses received from randomly selected consumers from 5 metro cities in India were critically analyzed for statistical significances. Findings suggest that in terms of readiness to adopt the consumers are showing a willingness to use shared mode of transport, major perceived key benefits are “cost”, “convenience” and “environmentally less polluting” while prominent challenges are “quality of service” and “customer satisfaction” when consumers engage with shared mobility services. Our study results will benefit public/private transport operators, policymakers, government agencies, and shared mobility consumers towards adoption, management, harnessing, and optimizing the potential benefits achieved through shared mobility strategies. The researchers propose an empirical exploration of consumers’ readiness to include multiple perception variables encompassing users from wider geographical contexts for gaining deeper insights into shared mobility adoption patterns as future research directions

Operationalization of the ecosystem services (ES) concept for improved natural resource management and decision support cannot, thus far, be rated as satisfactory. Participation of stakeholders is still a major methodical and conceptual challenge for implementing ES. Therefore, we conducted an online survey and a literature analysis to identify benefits and challenges of the application of ES in participatory processes. The results show that the purpose of stakeholder engagement is very diverse as a result of varying objectives, spatial scales and institutional levels of analysis. The complexity, terminology and (lacking) coherent classification of ES are pivotal aspects that should be accounted for in the design of studies to improve stakeholder participation. Although limitations of time and financial resources are bigger challenges than ES related ones, tailoring communication strategies and information for different stakeholder groups are of major importance for the success of ES studies. Results support the view that the potential benefits of applying ES, e.g., consensus finding, and development of integrated solutions, cannot be realized consistently across the different spatial scales and decision-making levels. Focusing on stakeholder processes represents a means to increase the relevance, reliability and impact of study results and to move participation in ES research from theory to reality.

Water Spring

Water springs are considered as one of the important natural resource for tourism due to its socio-economic, cultural, health and religious benefits. Tourists are motivated to visit the water springs due to various reasons like sacredness, health benefits, education and cultural enrichment.  Latvia is blessed with several water springs, which are potential attractions for the sacred water or holy water tourism. There are several studies conducted on various aspects of water springs in general. However, the research in the context of tourism, particularly motivations and interest of tourist is very scant. In this regard, aim of the paper is to know the motivations and potential benefits of the water spring tourism to tourist in Latvia. Initially authors reviewed existing literature to know the state of the spring tourism. Semi structured interviews and online-survey method to obtain visitors responses.  Interviews were held with the visitor, covering various aspects like motivations and benefits of water spring tourism. To the best of the author’s knowledge, very few studies conducted on spring tourism in Latvia, to provide a detailed overview on tourist motivations and potential benefits of visiting water spring tourism. Overall, the study results provide the basis for understanding the most frequently visited water spring resources by the tourists in Latvia. Nature appreciation, natural setting followed by mineral and health benefits are the major reasons to visit the water springs. Further, it allows decision makers to incorporate tourist opinion and their suggestions in the sustainable planning, promotion and management of water springs as tourist destinations in Latvia.

Random testing for alcohol and other drugs (AODs) in individuals who perform safety-sensitive activities as part of their aviation role was introduced in Australia in April 2009. One year later, an online survey (N = 2,226) was conducted to investigate attitudes, behaviors, and knowledge regarding random testing and to gauge perceptions regarding its effectiveness. Private, recreational, and student pilots were less likely than industry personnel to report being aware of the requirement (86.5% versus 97.1%), to have undergone testing (76.5% versus 96.1%), and to know of others who had undergone testing (39.9% versus 84.3%), and they had more positive attitudes toward random testing than industry personnel. However, logistic regression analyses indicated that random testing is more effective at deterring AOD use among industry personnel.

Background. Parkinson’s disease (PD) is neurodegenerative, causing motor, cognitive, psychological, somatic, and autonomic symptoms. Understanding PD patients’ preferences for novel neurostimulation devices may help ensure that devices are delivered in a timely manner with the appropriate level of evidence. Our objective was to elicit preferences and willingness-to-wait for novel neurostimulation devices among PD patients to inform a model of optimal trial design. Methods. We developed and administered a survey to PD patients to quantify the maximum levels of risks that patients would accept to achieve potential benefits of a neurostimulation device. Threshold technique was used to quantify patients’ risk thresholds for new or worsening depression or anxiety, brain bleed, or death in exchange for improvements in “on-time,” motor symptoms, pain, cognition, and pill burden. The survey elicited patients’ willingness to wait to receive treatment benefit. Patients were recruited through Fox Insight, an online PD observational study. Results. A total of 2740 patients were included and a majority were White (94.6%) and had a 4-year college degree (69.8%). Risk thresholds increased as benefits increased. Threshold for depression or anxiety was substantially higher than threshold for brain bleed or death. Patient age, ambulation, and prior neurostimulation experience influenced risk tolerance. Patients were willing to wait an average of 4 to 13 years for devices that provide different levels of benefit. Conclusions. PD patients are willing to accept substantial risks to improve symptoms. Preferences are heterogeneous and depend on treatment benefit and patient characteristics. The results of this study may be useful in informing review of device applications and other regulatory decisions and will be input into a model of optimal trial design for neurostimulation devices.

Abstract Background Developing a safe and effective vaccine will be the principal way of controlling the COVID-19 pandemic. However, current COVID-19 vaccination trials are not adequately representing a diverse participant population in terms of age, ethnicity and comorbidities. Achieving the representative recruitment targets that are adequately powered to the study remains one of the greatest challenges in clinical trial management. To ensure accuracy and generalisability of the safety and efficacy conclusions generated by clinical trials, it is crucial to recruit patient cohorts as representative as possible of the future target population. Missing these targets can lead to reduced validity of the study results and can often slow down drug development leading to costly delays. Objective This study explores the key factors related to perceptions and participation in vaccination trials. Methods This study involved an anonymous cross-sectional online survey circulated across the UK. Statistical analysis was done in six phases. Multi-nominal logistic models examined demographic and geographic factors that may impact vaccine uptake. Results The survey had 4884 participants of which 9.44% were Black Asian Minority Ethnic (BAME). Overall, 2020 (41.4%) respondents were interested in participating in vaccine trials; 27.6% of the respondents were not interested and 31.1% were unsure. The most interested groups were male (OR = 1.29), graduates (OR = 1.28), the 40–49 and 50–59 age groups (OR = 1.88 and OR = 1.46 respectively) and those with no health issues (OR = 1.06). The least interested groups were BAME (OR = 0.43), those from villages and small towns (OR = 0.66 and 0.54 respectively) and those aged 70 and above (OR = 1.11). Conclusions In order to have a vaccination that is generalisable to the entire population, greater work needs to be done in engaging a diverse cohort of participants. Public health campaigns need to be targeted in improving trial recruitment rates for the elderly, BAME community and the less educated rural population.

Abstract Investigating the underlying predictors of speeding behaviour deserves the full attention of research. This study aims to examine the effects of demographic variables on the perceived deterrent mechanisms and to predict speeding behaviour to target appropriate prevention programmes. In this study, 212 randomly selected drivers having a valid car driving licence participated in an online survey. The results revealed that demographic variables influenced drivers’ perceptions towards social and legal sanctions as well as material loss. The model revealed that two sanction-related constructs, that is, legal sanction (b = −0⋅227, P = 0⋅007) and material loss (b = −0⋅218, P = 0⋅005), as well as lax perception towards traffic accident (b = −0⋅176, P = 0⋅025), were the significant predictors of speeding behaviour. These findings suggested that prevention programmes should prioritise young and single drivers. The most effective targeted prevention programmes are highlighted accordingly based on the study results.

Belief Model

During the COVID-19 pandemic, the number of hospital visits and attendance at scheduled appointments have dropped significantly. We used the health belief model (in three dimensions) to examine the determinants of non-attendance of scheduled appointments in outpatient clinics due to the COVID-19 pandemic. Participants in Taiwan (n = 1954) completed an online survey from 10 April 10 to 23 April 2020, which assessed how people perceived and responded to the outbreak of a fast-spreading infectious disease. We performed both univariate and multivariate logistic regression to examine the roles of cognitive, affective, and behavioral health belief constructs in nonattendance at scheduled appointments. The results indicated that individuals who perceived high confidence in coping with COVID-19 were less likely to miss or cancel their doctor’s appointments, whereas individuals who reported high anxiety and practiced more preventive health behaviors, including avoiding crowded places, washing hands more often, and wearing a mask more often, were more likely to miss or cancel their appointments due to the COVID-19 pandemic. Non-heterosexual participants had a lower rate of nonattendance at scheduled appointments compared with heterosexual ones. The study results increase our understanding of the patients’ cognitive health beliefs, psychological distress, and health behaviors when assessing adherence to medical appointments during a pandemic.

Background: Hate crimes against Muslim Americans have increased exponentially in the past 20 years, but there is currently no scale for measuring perceived anti-Muslim discrimination in the United States. To fill this gap, this study used a mixed-method approach to develop scales for measuring perceived anti-Muslim discrimination. Method: Qualitative data informed the development and validation of the 19-item Societal Anti-Muslim Discrimination Index and the 9-item Interpersonal Anti-Muslim Discrimination Index. Quantitative data ( N = 347) were collected from Muslim Americans using an online survey and used to assess the anti-Muslim indexes. Results: Qualitative data contributed to the refinement scale items. Quantitative results indicated one-component models and modest to high reliability of the Interpersonal Anti-Muslim Discrimination Index (.77) and Societal Anti-Muslim Discrimination Index (.88) scales. Discussion: Study results established the validity of these novel scales for measuring the distinct facets of anti-Muslim discrimination not captured by the Everyday Discrimination Index. These scales will facilitate research on anti-Muslim discrimination and the health implications of this form of religious-based discrimination.

Main Components

In the context of the worldwide acute shortage of qualified personnel in healthcare organizations, one of the most relevant tools for attracting talented doctors to work is an employer brand. The authors analyzed the views of potential job seekers of a medical organization about an attractive, “ideal” employer. Basic research methods are a content analysis of scientific works and an online survey. Based on the content analysis of publications of two abstract databases – eLIBRARY and Web of Science, the work presents the dynamics of the authors’ activity over the past five years, the key focus of the work, and the representation of an employer brand in medical organizations. The analysis reveals that among the abundance and against the background of positive trends in the number of works, only four papers on the employer brand deals with the study of the context in health care organizations, which does not allow judging the disclosure of this topic and offers opportunities for further scientific research. The authors identified the main components of the concept of an employer brand followed by the world scientific community – the presence of a positive image; the set of benefits associated with working in a particular company; and a holistic employer image. These elements formed the basis of the survey. One hundred twenty-nine respondents took part in the empirical part of the study. The study results reflect key factors of the attractiveness of a medical organization as an employer – reputation, personnel care, the existence of a strong leader, competitive salary, possibility of development, and human relations. The paper presents the ideal employer characteristics, according to the respondents, stated in the authors’ concept.
