Critical information on the effects that truck parking shortages have on crucial stakeholders, truck drivers in particular, has historically been obtained through survey methods. However, survey methodologies rely heavily on generalizations, respondents’ memory, the recency effect in memory recall, or experiences that evoked strong feelings. To investigate detailed truck parking shortage impacts using a method less reliant on historical recollections, the researchers developed and implemented a 14-day truck parking travel diary study. A total of 148 U.S. drivers participated, providing detailed data for 2,035 days of parking activity and 4,763 unique stops. The analysis focused on truck parking topics that have a nexus to previous survey findings that relate to drivers, state departments of transportation and enforcement activities, and other stakeholders, to facilitate the comparison of truck parking survey data with the diary data. Generally, the truck parking diary findings corroborated survey results. Almost 90% of drivers parked in an unauthorized location at least once a week – supporting survey findings that a majority of drivers find parking is difficult at least once a week. Data on unauthorized parking demonstrated that time-of-day can affect the ease of finding available parking, with peak difficulty occurring during evening hours. Drivers primarily choose parking locations for the mandated 10-h hours-of-service breaks based on practical needs – proximity to route, restroom and shower access, and expected parking availability. The research findings can provide policy, regulatory, and infrastructure guidance to both private industry and public agencies.

This paper introduces a framework for inferring activity travel given nearby land use information that can be obtained from a location-based social network (LBSN) such as Foursquare. The first component of the framework implements a generic method for acquiring land use data from LBSN services, which is a prerequisite for the inference algorithm. Three inference algorithms are suggested, and situations in which each algorithm might be a better fit are discussed. Finally, a case study is presented for activity inference applied to a data set collected in the greater Toronto and Hamilton area, Ontario, Canada, during the fall of 2012. Results are encouraging and suggest that it is possible to infer daily activity travel automatically; this possibility could significantly reduce the burdens of personal travel surveys and allow for collection of long-period travel diary data that is not easily achievable with traditional survey methods.

AbstractInterdisciplinary research often involves analyzing data obtained from different data sources with respect to the same subjects, objects, or experimental units. For example, global positioning systems (GPS) data have been coupled with travel diary data, resulting in a better understanding of traveling behavior. The GPS data and the travel diary data are very different in nature, and, to analyze the two types of data jointly, one often uses data integration techniques, such as the regularized simultaneous component analysis (regularized SCA) method. Regularized SCA is an extension of the (sparse) principle component analysis model to the cases where at least two data blocks are jointly analyzed, which - in order to reveal the joint and unique sources of variation - heavily relies on proper selection of the set of variables (i.e., component loadings) in the components. Regularized SCA requires a proper variable selection method to either identify the optimal values for tuning parameters or stably select variables. By means of two simulation studies with various noise and sparseness levels in simulated data, we compare six variable selection methods, which are cross-validation (CV) with the “one-standard-error” rule, repeated double CV (rdCV), BIC, Bolasso with CV, stability selection, and index of sparseness (IS) - a lesser known (compared to the first five methods) but computationally efficient method. Results show that IS is the best-performing variable selection method.

Specific Symptoms

The terms used to describe symptoms of delayed senescence in soybean often are used inconsistently or interchangeably and do not adequately distinguish the observed symptoms in the field. Various causes have been proposed to explain the development of delayed senescence symptoms. In this article, we review published reports on delayed senescence symptoms in soybean, summarize current research findings, provide examples of terms related to specific symptoms, and present an overview of the results of a multi-state survey directed to soybean growers to understand their concerns about delayed soybean senescence. Some of these terms, such as green bean syndrome and green stem syndrome, describe symptoms induced by biotic factors, while other terms describe symptoms associated with abiotic factors. Some delayed senescence terms involve the whole plant remaining green while other terms include just the stem and other plant parts such as pods. In the grower survey, 77% reported observing soybean plants or plant parts that remained green after most plants in the field were fully mature with ripe seed. Most respondents attributed these symptoms to changes in breeding and choice of cultivars. At the end of this article, we standardized the terms used to describe delayed senescence in soybean.

PurposeThe present study aims to examine how consumers evaluate the extended human brands of athlete celebrities beyond their unique brand personality associated with sports. Athlete celebrities' unique image in sports is used as a human brand, and attitude toward the athlete brand extensions is investigated when the athlete's name is included in a new non-sport brand. The concepts of brand extensions were employed to develop the ideas of human brand extensions.Design/methodology/approachIn total, 198 participants answered online survey questions before and after being informed of athlete brand extensions. Partial least squares structural equation modeling is utilized to test the hypotheses.FindingsThe survey results indicated that athlete–product fit and image transfer positively influenced attitude toward the extension. In addition, attitude toward the athlete brand extensions was significantly influenced by consumers' pre-existing attitude toward the celebrity; however, not by celebrity's expertise.Originality/valueThe research findings imply that some brand extension concepts are applicable to human brands to understand the effectiveness of athlete brand extensions for non-sport products.

Purpose While mortgage markets have gradually emerged in many African countries, substantial barriers still hinder their growth and expansion. Affordability has been widely cited as a prominent issue that doggedly remains at the core of urban housing problems. Hence, this paper aims to investigate the determinants of mortgage price affordability. Design/methodology/approach Data were gathered using semi-structured questionnaires obtained from a sample drawn from three major West African mortgage financing institutions. Respondents rated the variables using a five-point Likert item rating. The survey results were analysed using exploratory factor analysis. Findings In total, 11 variables that influence mortgage affordability were categorised within five principal components, namely, economic factors, financial factors, property characteristics, developmental factors and geographical factors. Practical implications The results provide insightful guidance to policymakers and practitioners on how to mitigate affordability issues within Ghana’s fledgling mortgage market. Failure to address the mortgage price affordability conundrum will place enormous pressure upon social housing and rental accommodation. Originality/value The research findings expand existing frontiers of knowledge by investigating and reporting upon the determinants of mortgage price affordability. The work also engenders wider debate on the need to establish mortgage packages targeted at low-to-middle-income earners. The culmination of analysis and debate will provide a robust basis for developing a future housing policy framework.

As public sector agencies use the e-government model to improve delivery of their services, it is important that this model become integrated into education of future leaders of the public service. A fully scaled implementation of e-government requires more than simple automation of the existing processes. It can affect significantly the overall organizational structure of public agencies, their missions and goals, and the way they interact with customers and with each other. Because of its profound impact on the functions and even structure of government, implementing e-government involves significant challenges, including resistance to change and the problem of lack of information technology skills among public managers. To address these challenges, public affairs programs must include into their curricula courses that would prepare cadre qualified for the era of e-government. Survey results are presented outlining efforts of graduate public affairs programs to meeting demands related to the e-government model. Major components of the model are outlined and the extent to which these components are covered in graduate courses in leading public affairs programs is assessed.

Enterprise risk management is an area of growing interest for state departments of transportation in the United States. This research developed a risk register spreadsheet tool—applicable at the enterprise and program levels—that supports the user in identifying risk events, defining risk categories, and assessing the likelihood (probability) and consequence (effect) of an event occurring. A state-of-the-practice survey was conducted with regard to the use of risk register tools to support enterprise- and program-level risk management at U.S. state departments of transportation, international transportation agencies, and nontransportation organizations. On the basis of the survey results and to further inform development of the risk register tool, several organizations were selected for in-depth interviews to gather additional information on their risk management practices and use of risk register tools. The resultant risk register reflects information from the interviews and examples provided by the participants. The spreadsheet-based risk register is an editable template that does not use any macros or custom code. In addition to the editable template, two prepopulated examples—one for enterprise-level risk management and one for program-level risk management—were created. While the risk register tool can help facilitate good practice risk management, the findings of this research indicate that an organization's risk management governance along with staff commitment, availability, and capability to support risk management activities are equally, if not more, important to effective risk management as the risk register tool itself.
