The purpose of this study is to investigate certain aspects of a transportation choice model proposed by Krapfel and Mentzer (1982) pertaining to the influence of shipper perceptions on the selection of a mode. Specifically, this study attempts to identify the impact that shipper perceptions of intermodal and over-the-road truck service, as well as other characteristics of the shipper, have on intermodal usage. The research findings support the notion that shipper perceptions affect modal usage and indicate areas in which intermodal providers should focus their attention to improve intermodal usage.

This research proposes an innovative approach to evaluate modal shift from the road-only to the combined sea-road transport in order to implement new policies and introduce a Decision Support System (DSS) for the transportation planner’s decision. The impact of these is carried out by using an innovative simulation tool which has the capability to simulate the real choice process of all stakeholders involved, specifically modelling the freight forwarder’s point of view. The model runs as a single-agent based simulation which uses a multimodal network with detailed zoning. The simulation tool, capable of simulating the assignment of the whole network simultaneously, consists of a path choice model and a mode choice model for each o/d pair considered, establishing o/d pairs suitable and not suitable for modal shift. Three policies have been designed and tested through the simulation tool with an application in the Italian context: (1) internalization of the external costs of heavy vehicles; (2) introduction of a bonus for shipping companies; (3) design of new Ro-Ro services. The most affecting policy concerns an increase of speed of some Ro-Ro services to 22 kn, proposing a good balance between the navigation costs and the potential demand attracted.

PurposeThe paper aims to explore the influence of cybersecurity on the semantic orientation of the sports consumers. Focusing on both sport and esports, this study finds the social media factors contributing in the sentiment formation and commenting behavior on Twitter and proposes a scheme for attitude modulation through identification of highly engaged nano-influencers.Design/methodology/approachExperimental design was used as the research methodology. Data mining from Twitter using RStudio software was conducted using the keyword “cybersecurity” during the time of pandemic. Final corpus of 31,891 tweets were considered for the study. Initial sentiment analysis has been conducted to explore the consumer's emotional inclination towards cybersecurity. Further through generalized equation modeling the impact of social media attributes over the consumer's posting behavior has been analyzed.FindingsThe research findings reveal that users are inherently positive towards cybersecurity adoption in sports and the factors such as number of tweets, number of positive words contained in these tweets and the authenticity of the information source boost the pre-established tweeting behavior. However, the influx of information from non-organizational sources such as trending topics and discussions have negative impact over the users.Originality/valueThis study is first to explore the role of nano-influencers as communication moderators over digital social platforms. This study offers a new understanding of key contributing attributes of sentiments formation over social media and offers a scheme of selection of nano-influencers to modulate the pre-established sentiments of the users. Finally, the current study offers valuable insights into social media engagements and selection of nano-influencers for practicing marketing managers.

The crisis of confidence in psychology has prompted vigorous and persistent debate in the scientific community concerning the veracity of the findings of psychological experiments. This discussion has led to changes in psychology's approach to research, and several new initiatives have been developed, many with the aim of improving our findings. One key advancement is the marked increase in the number of replication studies conducted. We argue that while it is important to conduct replications as part of regular research protocol, it is neither efficient nor useful to replicate results at random. We recommend adopting a methodical approach toward the selection of replication targets to maximize the impact of the outcomes of those replications, and minimize waste of scarce resources. In the current study, we demonstrate how a Bayesian re--analysis of existing research findings followed by a simple qualitative assessment process can drive the selection of the best candidate article for replication.

The Best Value Approach (BVA) has been used as a method to procure and manage services. As the BVA is further proliferated, there are applications of the BVA which deviate from the standard approach which are labeled as hybrid processes. This research focuses on better understanding BVA hybrid projects and the implications that may arise with such deviations. Using case study research, the BVA was used to procure services for the construction of ships. The research findings show the impact of hybrid applications of the BVA including (1) the selection of suppliers based on decision making instead of expertise (2) attempts to share and transfer risk, (3) incomplete clarification phase planning by expert suppliers, and (4) incomplete use of the Weekly Risk Report and Director’s report to track project deviation. The resulting hybrid application was found to have increased costs, increased decision making, and created a non-transparent environment. Suggestions have been made to improve upon these areas by applying the BVA structure including a selection process to identify expertise and a project management process which utilizes the supplier’s expertise to create a structure of transparency through performance metrics.

Abstract For people with spinal cord injuries, the selection of a wheelchair and seating system involves many factors. This clinical perspective describes a model that includes consideration of the person, the wheelchair, the immediate environment between the person and the wheelchair, the intermediate environment of the home and work, and the community environment. The seated posture is examined biomechanically, and literature is reviewed that highlights the differences in the seated position of people with spinal cord injuries and people without spinal cord injuries. Reports regarding overuse injuries of the shoulder and wrists are discussed along with methods of relieving pressure at the buttock and seat interface. The impact that research findings should have on current clinical practice and the need for more research to provide evidence to either support or change current practice are discussed.

Abstract In a large city, there are many congestion problems, so the selection of the fastest route to reach the destination is needed. The city of Bandung is one of the big cities in Indonesia which has a fairly crowded traffic density and tends to be a lot of congestion in it. So we need a study that can discuss the path of independence. In the study to determine the shortest path there are several algorithm options to solve it. This research was conducted using the Bellman Ford algorithm to try to solve the problem of selecting the fastest path. The case that will be focused on in this study covers the route that starts from Ir. H. Juanda street and ends at the Leuwipanjang bus terminal. The road node that will be passed is taken from several main points that will be passed. Calculation of coordinates will be calculated using the concept of graph and haversine formula.

Selection of suitable Journal for publication of research findings in a peer-reviewed Journal is very critical and challenging for researchers. Selection of Journal for publication involves many factors, where the main factor is Journal metrics. In light of the proliferation of journals, some journals have come under increased scrutiny recently with terms such as questionable, illegitimate, dishonest, used to describe these journals. Generally, the young researchers or the first-time authors, would like to publish their findings in a less reputed Journal with very less rejection rate, as they want to publish their articles quickly. Wrong choice of journal for publishing spells outright rejection. Even if the article is very encouraging with sound and rigorous scholarly work, it will not stand the test. Another option for authors is to consult with librarians affiliated with organization or local public library. Librarians are well-suited to provide guidance in helping authors with selecting quality journals to consider for publication. Transparency and objectives are essential elements for scientific research and peer review process. Bibliographic software such as EndNote or RefWorks assist the authors to format reference section and to perform corrections suggested by reviewers. Hence, this review was delineated to provide an insight for the researchers to prefer a Journal based on the impact factor, H-index, SNIP, SJR and timeline of publication.

Abstract. The Sympson-Hetter (1985) method provides a means of controlling maximum exposure rate of items in Computerized Adaptive Testing. Through a series of simulations, control parameters are set that mark the probability of administration of an item on being selected. This method presents two main problems: it requires a long computation time for calculating the parameters and the maximum exposure rate is slightly above the fixed limit. Van der Linden (2003) presented two alternatives which appear to solve both of the problems. The impact of these methods in the measurement accuracy has not been tested yet. We show how these methods over-restrict the exposure of some highly discriminating items and, thus, the accuracy is decreased. It also shown that, when the desired maximum exposure rate is near the minimum possible value, these methods offer an empirical maximum exposure rate clearly above the goal. A new method, based on the initial estimation of the probability of administration and the probability of selection of the items with the restricted method ( Revuelta & Ponsoda, 1998 ), is presented in this paper. It can be used with the Sympson-Hetter method and with the two van der Linden's methods. This option, when used with Sympson-Hetter, speeds the convergence of the control parameters without decreasing the accuracy.
