A New Approach to Proportional Hazards Modeling for Estimating Customer Lifetime Value

Estimating customer lifetime value (CLV or LTV) is extremely important for making better business decisions. The proposed flexible proportional hazards model allows an estimation of lifetime value in contractual settings. This approach takes advantage of a churn model, which is assumed to be available.Comment: 6 page

This article presents the results of the research which deals with the current level of development of small and medium enterprises (SMEs) in Sverdlovsk region. The study analyses the statistics of entrepreneurship development as well as Russian and international experience in this sphere. It also includes a sociological survey of entrepreneurs’ satisfaction with the business climate in the region. The research was aimed at elaborating guidelines for the long-term development of a regional entrepreneurship support system. This system seeks to facilitate the implementation of the ‘Strategy for the Development of Small and Medium Enterprises in Sverdlovsk Region before 2030’. As a result, an amalgam of strategic responses for the development of SMEs is presented. The completed response comprises measures intended to address the problems entrepreneurs face by developing SME support tools; to solve the endemic problems of the sector by improving the system of regional SME support; and to promote the realization of concrete priority areas for entrepreneurship development.The research work was carried out in collaboration with the Ural Federal University n.a. the First President of Russia B.

Factors Contributing to Ladder Falls and Broader Impacts on Safety and Biomechanics

Ladder falls cause disabling injury and death in the workplace and at home. Numerous scenarios lead to ladder falls given the variation in ladder types and how they are used. Of the potential factors influencing ladder fall risk under these different scenarios, many have yet to be investigated. This dissertation used a multifaceted approach to determine ladder fall risk factors. Specifically, this dissertation tested younger and older adults, designed occupational and domestic based ladder experiments, and investigated factors that precede and follow a ladder falling event. Aim 1 of this dissertation identified individual factors associated with safe and effective domestic ladder use among older adults. Balance measured with clinical assessments was a primary predictor of safe and effective ladder use. Aim 2 of this dissertation determined individual, environmental and biomechanical factors that aid in arresting a falling event from a ladder. Ascending climbs, males, greater upper body strength, higher hand placement during recovery and reestablishing at least one foot back onto the ladder during recovery were associated with reduced ladder fall severity (i.e. better recovery). Surprisingly, glove condition was not found to contribute to ladder fall severity. Hand-rung forces were correlated with the severity of the falling event and not an individual’s ability to generate force, suggesting that these forces are dependent on the circumstances of the perturbation. Findings from this dissertation may guide fall interventions (e.g. screenings, improvements in safety standards, perturbation response training, ladder re-design). Therefore, this work is expected to have impact on the safety field by reducing ladder fall injuries. Furthermore, this work contributes new knowledge to the biomechanics of ladder use and fall recovery. As part of a larger strategy to improve safety for all populations, increased diversity is needed in the Science, Technology, Engineering, and Mathematics (STEM) fields. Aim 3 of this dissertation utilized biomechanics as a link to develop a student-interest based pedagogy to improve engagement of underrepresented groups in the STEM fields. This work found lectures tailored to student interests to increase student engagement. Long-term effects from this work can increase diversity in the STEM fields including safety

Intersecting Identities and the Work of Faculty Development

On increasingly diverse college campuses, faculty members look to faculty developers for support in facilitating difficult classroom dialogues and in handling challenging interactions around their students’ identities and their own. We propose that faculty developers’ work around issues of diversity, social justice, and inclusive excellence can be enhanced by developing a foundation in the theory of intersectionality, which engages the complexity of identity and the resulting power structures that inform institutions. We discuss this theoretical perspective and provide examples of faculty development initiatives that can be strengthened through the use of an intersectional lens

d/Deafness and the Basic Course: A Case Study of Universal Instructional Design and Students Who are d/Deaf in the (aural) Communication Classroom

The primary purpose of this essay is to suggest ways to create a universally inclusive curriculum, which, by definition, addresses the learning needs of all students, including students with disabilities or, in this case, students who are deaf or hard-of-hearing. Presented with the opportunity of having a d/Deaf students in a public speaking class, we reflect on the accommodations made, the assumptions inherent in an inclusive classroom, and the ideology of ableism. Because d/Deafness is as much a cultural identity as an auditory condition, we also address how to create safe learning environments for diverse student populations through the use of Universal Instructional Design

Ladder use in older people: Type, frequency, tasks and predictors of risk behaviours

Ladder fall and injury risk increases with age. People who present to a hospital after an injurious ladder fall have been surveyed, but little is known about ladder use in the community. The purpose of this study was to: (1) document salient factors related to ladder safety, and (2) determine physical, executive function, psychological and frequency-of-use factors associated with unsafe ladder use in older people. One hundred and two older people (aged 65+ years) were recruited. Participants completed questionnaires on demographics, health, and ladder use (type, frequency, task, behaviours) and underwent assessments of physical and executive function ability. Results showed both older men and women commonly use step ladders (61% monthly, 96% yearly), mostly inside the home for tasks such as changing a lightbulb (70%) and decorating (43%). Older men also commonly use straight ladders (27% monthly, 75% yearly), mostly outside the home for tasks such as clearing gutters (74%) and pruning trees (40%). Unsafe ladder use was more common in males and individuals with greater ladder use frequency, greater quadriceps strength, better upper limb dexterity, better balance, better stepping ability, greater self-reported everyday risk-taking, a lower fear of falling, and fewer health problems compared to their counterparts (all p < 0.05). These findings document ladder use by older people and provide insight into unsafe ladder behaviours that may be amenable to interventions to reduce ladder falls and associated injuries

Attentional biases towards familiar and unfamiliar foods in children. The role of food neophobia

Familiarity of food stimuli is one factor that has been proposed to explain food preferences and food neophobia in children, with some research suggesting that food neophobia (and familiarity) is at first a predominant of the visual domain. Considering visual attentional biases are a key factor implicated in a majority of fear-related phobias/anxieties, the purpose of this research was to investigate attentional biases to familiar and unfamiliar fruit and vegetables in 8 to 11 year old children with differing levels of food neophobia. To this end, 70 primary aged children completed a visual-probe task measuring attentional biases towards familiar and unfamiliar fruit/vegetables, as well as the food neophobia, general neophobia and willingness to try self-report measures. Results revealed that as an undifferentiated population all children appeared to demonstrate an attentional bias toward the unfamiliar fruit and vegetable stimuli. However, when considering food neophobia, this bias was significantly exaggerated for children self-reporting high food neophobia and negligible for children self-reporting low food neophobia. In addition, willingness to try the food stimuli was inversely correlated with attentional bias toward the unfamiliar fruits/vegetables. Our results demonstrate that visual aspects of food stimuli (e.g. familiarity) play an important role in childhood food neophobia. This study provides the first empirical test of recent theory/models of food neophobia (e.g. Brown & Harris, 2012). Findings are discussed in light of these models and related anxiety models, along with implications concerning the treatment of childhood food neophobia
