Context:Assessment of running mechanics has traditionally been conducted in laboratory settings; the advancement of wearable technology permits data collection during outdoor training sessions. ...Exploring changes in running mechanics across training session types may assist runners, coaches, and sports medicine clinicians in improving performance and managing injury risk.Objective:The purpose of this investigation was to examine changes in running mechanics based on routine training session types.Design:Descriptive observational studySetting:Field-based, universityMethods:Running mechanics data (i.e., impact g (PI), stride length(SL), braking g (BF), total shock, and cadence, and ground contact time (GCT)) for National Collegiate Athletic Association (NCAA) Division 1 distance runners (males, n=20) were collected using RunScribe™ sensors mounted to the laces during training sessions (long run (LR), interval run (IR), and/or recovery run (RR)) during a one-week period.Results:Repeated measures ANCOVA with Greenhouse Geisser correction, with training session pace as a covariate, determined no statistically significant differences in spatiotemporal or kinetic measures across the three training session types. Cadence and SL were inversely related in all training sessions (LR: r=−0.673, p=0.004; IR: r=−0.893, p=<0.001; RR: r=−0.549, p=0.023). Strong positive correlations were seen between PI and total shock in all training sessions (LR: r=0.894, p<0.001; IR: r=0.782, p=<0.001; RR: r=0.922, p<0.001). GCT increased with SL during LR training sessions (r=0.551, p=0.027) and decreased with BF in IR training sessions (r=−0.574, p=0.016) and cadence in RR training sessions (r=−0.487, p=0.048).Conclusion:Running mechanics were not statistically different between training session type in collegiate distance runners when controlling for training session pace. The use of wearable technology provides a tool to provide necessary data during overland training to inform training and program design.
The open government data (OGD) movement has rapidly expanded worldwide with high expectations for substantial benefits to society. However, recent research has identified considerable social and ...technical barriers that stand in the way of achieving these benefits. This paper uses sociotechnical systems theory and a review of open data research and practice guidelines to develop a preliminary ecosystem model for planning and designing OGD programs. Findings from two empirical case studies in New York and St. Petersburg, Russia produced an improved general model that addresses three questions: How can a given government's open data program stimulate and support an ecosystem of data producers, innovators, and users? In what ways and for whom do these the ecosystems produce benefits? Can an ecosystem approach help governments design effective open government data programs in diverse cultures and settings? The general model addresses policy and strategy, data publication and use, feedback and communication, benefit generation, and advocacy and interaction among stakeholders. We conclude that an ecosystem approach to planning and design can be widely used to assess existing conditions and to consider policies, strategies, and relationships that address realistic barriers and stimulate desired benefits.

Many grocery retailers carry a loyalty program (LP). However, little is known under what conditions these programs are more or less effective. We provide a contingency framework that considers ...various design, retailer, and country characteristics that can moderate an LP's impact on a retailer's sales productivity. We test the framework across a large sample of 358 grocery banners from a broad cross-section of 27 western and eastern European countries. We find a positive effect of the more basic LP variant that offers direct and immediate rewards. This positive effect, however, disappears when retailers operate a more complex progressive-reward system and when they are part of a multivendor program. An LP's impact also differs between retailers and countries: it is lower when operated by discounters, and higher in countries that are more individualistic and long-term oriented, and where fewer competitors also carry a loyalty program.
Previous studies so far have investigated various aspects of cyberbullying. Using meta‐analytic approaches, the study was primarily to determine the target factors predicting individuals’ ...perpetration and victimization in cyberbullying. A meta‐analysis of 77 studies containing 418 primary effect sizes was conducted to exam the relative magnitude of demographic, individual, and contextual predictors. Several study characteristics (i.e., sample age, sample gender, study location, publication status, and publication year) were further analyzed as moderators. The results showed the average effect size of each predictor for both cyberbully and cybervictim groups. Several significant shared and unique predictors were identified as important factors for designing effective prevention and intervention programs. The implications of the findings for future research were discussed in relation to interventions on cyberbullying.
Abstract In Ecuador, there are qualitative and quantitative housing deficits that must be covered with materials that produce seismic-resistant, energy-efficient buildings that do not require a large ...amount of energy to be produced. Several studies indicate that the answer lies in straw bale structures. However, for these to be considered by designers, aids are needed to facilitate their structural modeling in specialized computer programs. Through literature reviews, the present research proposes a model that adapts the specific structural considerations of straw bale buildings to the tools available in a design program.
Scholars, practitioners, policymakers, and accreditors challenge business schools to extend their impact beyond academia and into the real world. Many management academics have responded by becoming ...involved in business training programs that seek to improve the well-being of marginalized individuals. However, work that conceptualizes and measures the efficacy of these activities has not been systematically analyzed. In this article, we provide the first review. We find that the research is dominated by examinations of short-term, individual-level outcomes, such as securing employment. Yet little is written about the impact of business training programs (especially over time) at either a collective or system level. We use our review to argue for theoretically informed approaches to redress this gap, highlighting underemphasized directions for future research. We also provide recommendations to assist program design, noting that good practice involves hybrid models of education that build capacity within marginalized communities. Further, program designs ought to support broader social goals, such as helping these communities to thrive.

In the current era of globalization, technology is advancing rapidly, and computers are one of the technologies which are one of the tools used to make it easier to find problems, of course, it is ...also supported by hardware, software and brainware. Mobile stores require an information system that supports and provides satisfactory service to buyers. For this reason, the author makes this final project regarding the program for selling cellphones at the cellphone store which currently does not use a computerized system. The system at the cellphone store usually still uses a manual system. Starting from recording sales notes to bookkeeping sales reports that are still recorded in the books. This can allow for errors in recording, ineffectiveness and inefficient calculations in large numbers. And can cause inaccurate reports made. The use of the program is one solution to solving sales problems in the cellphone store. Therefore, with the use of a sales program, it is possible to further assist sales activities in the cellphone store.
Retailers increasingly adopt temporary loyalty programs (TLPs), in which consumers have limited time, often less than half a year, to save stamps and redeem highly discounted rewards. These programs ...often run alongside the retailers’ permanent loyalty programs in an attempt to increase customer engagement. Despite the growing popularity of TLPs, the literature on the topic remains limited. We address this gap by looking at the redemption rate, the industry’s primary success indicator, of almost 900 TLPs across a broad set of grocery retailers in 45 countries. We study the effects of four key design characteristics (the duration of the program, the discount offered, the spending requirement before an award can be redeemed, and the reward depth) on the redemption rate, and explore how these effects vary across a broad range of retailer and country characteristics. In doing so, we control for both a retailer’s potential self-selection into running a TLP and the potential endogeneity of the subsequent design choices. We derive a set of actionable results on how to design successful TLPs and show that high redemption rates are not only beneficial for the program operator and reward manufacturer, but also translate into higher sales and profit for the retailer.
Abstract Research Summary Accelerator programs provide valuable market feedback and education to participants that may improve startup performance. However, it is unclear whether the average effect ...of accelerator participation on startup performance post acceleration is positive, and if so, how this effect varies with accelerator program design. We analyze data from 8580 startups that made it past the initial selection stage at 408 accelerators in 176 countries between 2013 and 2019. We compare accelerated and non‐accelerated startups and find a positive average effect of accelerator participation on startup performance post acceleration. Moreover, we find that this effect varies substantially with program design, and depends on venture stage, industry, and founder expertise. Our findings highlight the impact of program design on the benefits that startups derive from accelerator participation. Managerial Summary The purpose of this study is to determine whether participation in startup accelerator programs generally leads to improved startup performance post acceleration and how the benefits of participation might vary with the design of these programs. We analyze data from 8580 startups that applied to and passed the initial selection phase at 408 accelerators in 176 countries over multiple cohorts between 2013 and 2019. Our results indicate that on average, startups that participate in accelerators perform better than those that are also selected but not accelerated. Furthermore, we find that the benefits that startups gain from being accelerated vary with the design of the program. Our findings highlight the importance of accelerator program design in influencing the extent of improvement in startup performance post acceleration.
