This paper analyzes the impact of obesity on the probability of a motor vehicle fatality (highway death rate) and on its component probabilities: the probability of a fatality, given a crash (vulnerability rate) and the probability of a crash (crash rate).

Using state-level data for 1995–2015, the paper estimates models explaining all three rates. Explanatory factors include obesity and a representative set of potential determinants.

Results indicate that obesity has a statistically significant positive relationship with the highway death rate and the crash rate. Also having a statistically significant positive association with at least one of the three rates are the proportions of young and old drivers, alcohol consumption, the ratio of rural to urban vehicle miles and temperature. Factors with a statistically significant negative relationship with at least one of the rates include primary seat belt laws and precipitation. In 2016, a total of 928 traffic fatalities could have been avoided if obesity rates decreased by one percentage point.

Seat belts and crash dummies should be better designed to fit and represent those with higher BMIs, and education efforts to increase seat belt use should be supplemented with information about the adverse impact of obesity on highway safety.

This paper uses 21 years of state-level information, including socio-economic and regulation data, and contributes to the existing research on the relationship between obesity and highway safety.

In the fall of 1996, Walstad suggested that the economics profession needed to obtain the students' perspective on the choice of major. The purpose of this paper is to examine the factors that influence the choice of major.

To recruit majors and to address Walstad's concern, economics and non‐economics majors were surveyed to determine which factors they consider important when choosing a major and to better understand why some students never consider economics.

The results suggest that interest in the subject, expected marketability, performance in major classes, and the approachability and teaching reputation of the faculty are influential to the choice of major.

The results may help the profession address enrollment issues, including the disproportionate number of women in the major.

Purpose – Teachers should plan instruction that integrates digital tools into instruction in meaningful ways to promote students’ use of multimodalities. Therefore, it is useful for teacher educators to expose pre-service teachers (PSTs) to a systematic approach to integrating a variety of digital tools into their instruction. In this chapter, the authors discuss on the Technology Integration Planning Cycle (TIPC; Hutchison & Woodward, 2014a, 2014b) as one systematic approach for teachers and teacher educators to consider.

Design – This chapter describes the promise of using the TIPC with PSTs to demonstrate and practice how to plan effective literacy instruction to support students’ use of multimodalities. The chapter includes a rich description of how the use of the TIPC might take shape in a literacy methods course based on a composite of courses, students, and activities that the authors have experimented with over time.

Findings – Using the TIPC with PSTs requires a structured approach (Hutchison & Colwell, 2016) that includes modeling and scaffolding of PSTs’ knowledge of technology and pedagogy (Beschorner & Kruse, 2016). Therefore, the Gradual Release of Responsibility (Pearson & Gallagher, 1983) might be valuable to consider as a guiding framework for planning course activities and assignments that utilize the TIPC. This chapter provides an example of this type of instruction.

Practical Implications – There is a significant need to prepare twenty-first century learners to read and write multimodal text. Thus, supporting PSTs to increase their self-efficacy in using technology for instruction and providing the conditions necessary to develop pedagogical beliefs that make it likely for them to be able to integrate technology in meaningful ways is vital (Ertmer, 2005). Using the TIPC in a literacy methods course in the ways that model and scaffold its use, might be one approach to creating these conditions.

Locus of control (LOC) is the manner in which one attributes their ability to make change in life. This could be through others, fate or chance (externalised), or through oneself (internalised). An internalised LOC results in greater self-belief in the ability to change one's behaviour. Non-disabled offenders with an internalised LOC are more likely to benefit from treatment through therapy and in turn have reduced rates of re-offending. The relationship between LOC and response to treatment is only understood in a limited way for offenders with intellectual disability (ID) who participate in treatment programmes. The paper aims to discuss these issues.

To better understand LOC for offenders with ID, this paper investigates its role in community-based therapy outcomes along with its use as a common pre-/post-measure of treatment success in mainstream offender populations. Drawing upon these findings information more specific to people with ID will be discussed.

This paper will then explore the importance of LOC in treating offenders with ID through a review of the current published literature, which generally indicates offenders with ID demonstrate a tendency towards an external LOC in comparison with non-disabled or non-offender groups.

Given the negative implications for treatment that external LOC may play, several significant therapeutic strategies that can contribute to development of internalised LOC are discussed, in addition to a consideration of other possible variables separate from ID that may play a role in both developing or perpetuating an external LOC.

Young children write to learn the alphabetic code, take notes to help them remember, and provide meaningful text to others. These are cognitively and linguistically complex processes. Reciprocal relationships among the development of writing, the purposes of writing, and the learners of interest impact instructional approaches and student outcomes. Teachers can increase success when they provide explicit and systematic self-regulation and writing instruction, view children as collaborators in the process, provide scaffolding that gradually shifts the responsibility to the children, and adapt instruction to meet the abilities and interests of the children. Effective instructional practices for young children with disabilities or who are at risk, are presented, for example, scaffolded writing, the use of graphic organizers, and self-regulated strategy development.

History-based trade books have an important and expanding role in various curricula. Contemporary education initiatives urge English and language arts educators to spend half their time on non-fiction and history and social studies teachers to include diverse sources starting in the early grades. Diverse professional organizations annually make financial commitments to promote new trade books. Research indicates misrepresentations abound in history-based trade books, yet few empirical studies have been completed. The purpose of this paper is to research examine the historical representation of Abraham Lincoln, arguably the most consequential nineteenth-century American.

Data samples included trade books intended for early grades and middle grades students. These grade ranges were selected because these students have the least prior knowledge and are perhaps most dependent on the text. Qualitative content analysis research methods were employed.

Misrepresentations emerged regarding Lincoln’s poverty, actions, motivations for actions, and implications of his actions as seemingly necessary historical content was minimized, vaguely included, or omitted. Findings are juxtaposed across and between selected grade ranges.

Discussion focused on the significance of findings for teachers and researchers. Teachers are guided to supplement trade books with primary sources to position students to distinguish historical misrepresentations.

This research builds on previous scholarship on Lincoln-based trade books by expanding grade range, data samples and research questions.

This paper tests whether Bayesian A/B testing yields better decisions that traditional Neyman-Pearson hypothesis testing. It proposes a model and tests it using a large, multiyear Google Analytics (GA) dataset.

This paper is an empirical study. Competing A/B testing models were used to analyze a large, multiyear dataset of GA dataset for a firm that relies entirely on their website and online transactions for customer engagement and sales.

Bayesian A/B tests of the data not only yielded a clear delineation of the timing and impact of the intellectual property fraud, but calculated the loss of sales dollars, traffic and time on the firm’s website, with precise confidence limits. Frequentist A/B testing identified fraud in bounce rate at 5% significance, and bounces at 10% significance, but was unable to ascertain fraud at the standard significance cutoffs for scientific studies.

None within the scope of the research plan.

Bayesian A/B tests of the data not only yielded a clear delineation of the timing and impact of the IP fraud, but calculated the loss of sales dollars, traffic and time on the firm’s website, with precise confidence limits.

Bayesian A/B testing can derive economically meaningful statistics, whereas frequentist A/B testing only provide p-value’s whose meaning may be hard to grasp, and where misuse is widespread and has been a major topic in metascience. While misuse of p-values in scholarly articles may simply be grist for academic debate, the uncertainty surrounding the meaning of p-values in business analytics actually can cost firms money.

There is very little empirical research in e-commerce that uses Bayesian A/B testing. Almost all corporate testing is done via frequentist Neyman-Pearson methods.

The purpose of this paper is to provide a methodology for the development of a plan to incorporate information literacy education into interior design programs in higher education.

After providing background information about the role of the liaison to the interior design department, the process of the project implementation is described in detail. The project demonstrates how students learned to move beyond a mere ability to access information.

The project demonstrated that in order for students to acquire critical thinking skills, both librarian and faculty must determine what skills the students should master throughout their program. Students' work showed that information literacy produces better results when it is applied in stages and with objects that build on previous skills.

The research fills a gap in the published literature, which offers limited resources on how information literacy is taught, used and assessed in the interior design discipline.
