This article analyzes some available bike mobile applications as an alternative to bike computers, as known as cycle computers or speedometers or speed sensors. We have stored a lot of datasets recorded from different mountain bike routes; in this study, we analyzed two routes only. Most mobile cycling applications estimate fields such as speed, heading, slope, distance, VMG (Velocity Made Good) and pace (cadence). However, it is necessary to calculate the relationship between cadence and power in pedaling so that cyclists know the appropriate moment to apply force to their legs to improve the torque. We studied four cycling apps and one bike computer. The contribution of this paper lies in the fact that it reports and compares measurements of cycling workouts using four mobile applications for cycling, at the same time these measurements are compared against a speedometer; the differences in distance and speed between the mobile apps used in this study are slightly notorious. We also show comparative tables and graphs, and performance evaluation of biking routes in two different bike routes.

This article analyzes some available bike mobile applications for smartphones as an alternative to bike computers (Cycle Computers or speedometer or speed sensors). We have records of a large number of MTB (Mountain Bike) datasets, 219 datasets were recorded on 4 different routes. These applications create maps and profiles from geographic data. Inputs can be in GPS data (tracks and waypoints), driving routes, street addresses, or simple coordinates. Most applications estimate fields such as speed, heading, slope, distance, VMG (velocity made good) and pace (cadence). However, it is necessary to calculate the relationship between cadence and power in pedaling so that cyclists know the appropriate moment to apply power to their legs to improve the torque. This paper shows tables, comparative graphs, and performance evaluation of biking routes in four different cycling mobile applications.

Although individuals increasingly use mobile applications (apps) in their daily lives, uncertainty exists regarding how the apps will use the information they request, and it is necessary to protect users from privacy-invasive apps. Recent literature has begun to pay much attention to the privacy issue in the context of mobile apps. However, little attention has been given to designing the permission request interface to reduce individuals’ perceived uncertainty and to support their informed decisions. Drawing on the principal–agent perspective, our study aims to understand the effects of permission justification, certification, and permission relevance on users’ perceived uncertainty, which in turn influences their permission authorization. Two studies were conducted with vignettes. Our results show that certification and permission relevance indeed reduce users’ perceived uncertainty. Moreover, permission relevance moderates the relationship between permission justification and perceived uncertainty. Implications for theory and practice are discussed.

Purpose The topic of employees’ unethical pro-organizational behavior (UPB) has attracted more and more interest in both practice and academic fields. However, previous studies have mainly investigated the antecedents of UPB and little research has discussed the outcome variables. This study aims to provide a comprehensive understanding of the effect mechanism of UPB on employee performance evaluation rated by a supervisor through a leader-member exchange (LMX) and the moderating role of supervisor bottom-line mentality (BLM). Design/methodology/approach This study used a sample consisting of 304 employees and 96 supervisors in several manufacturing firms in China. The authors used hierarchical linear modeling to test the hypotheses, as this was cross-level research. In addition, this paper also uses Mplus7.4 to test the moderating effects of supervisor BLM on the indirect effects between the UPB and performance evaluation by a moderated path analysis. Findings The results confirm that UPB is positively related to performance evaluation rated by supervisors. Additionally, the mediating effect of LMX in the relationship between UPB and performance evaluation is successfully demonstrated. Furthermore, supervisor BLM cross-levelly moderates the relationship between UPB and LMX, as well as moderates the mediation effect of LMX on the correlation between UPB and performance evaluation. Research limitations/implications The primary contribution of this research is building a cross-level model for the effect of UPB on followers’ performance evaluation scored by the supervisor and thereby extending the nomological networks of both UPB and performance evaluation literature. Another contribution the study makes to the literature is that it provides a new perspective to understand how UPB relates to followers’ performance evaluation. Originality/value This is the first study about how and when UPB predicts followers’ performance evaluation rated by the supervisor.

This study examines how the adoption of proactive socialization behaviors by temporary agency workers is related to contract renewal intention of the supervisor in the client organization in which they are assigned. We propose that the adoption of such behaviors will be associated with a favorable performance evaluation from the supervisor in the client organization, and in turn, to his or her contract renewal intention through two mechanisms, namely, role clarity and leader–member exchange (LMX), which refers to the quality of the relationship between the temporary worker and his or her supervisor. Data were collected from 217 worker–supervisor dyads. Results indicate that information-seeking behavior is related to performance evaluation through role clarity. This indirect relationship is however negative, as greater role clarity relates negatively to performance evaluation. Our results also show that LMX acts as a mediator between feedback seeking, boss-relationship building, and performance. Finally, favorable performance evaluation is positively associated with contract renewal intention.

Stab resistance compound fabric is frequently used in daily life, industry, military and aerospace. In this study, Nylon 6 and Polyester short fibers were mixed in ratio of 70:30. The mixture was needle punched at speed 300 needle/min to form a stab resistant fabric. The non-woven fabric matrix, non-woven fabric/grid matrix, non-woven/water-bone polyurethane (PU), and matrix/grid/water-bone PU, were put to test their tensile stress, tear stress, and stab resistance. Latter, the most stab resistant compound matrix was constructed in lamination structures to examine the relationship between thickness and stab resistance. The result showed that stab resistance of the non-woven/grid/water-bone PU compound fabric was 115 N; the triple-layered sample D was 208 N.

In this paper, we propose a two-step data-analytic approach to the promotion planning for mobile applications (apps). In the first step, we use historical sales data to estimate the app demand model and quantify the effect of price promotions on download volume. The estimation results reveal two interesting characteristics of the relationship between price promotion and download volume of mobile apps: (1) the magnitude of the direct immediate promotion effect is declining within a multiday promotion; and (2) due to the visibility effect (i.e., apps ranked high on the download chart are more visible to consumers), a price promotion also has an indirect effect on download volume by affecting app rank, and this effect can persist after the promotion ends. Based on the empirically estimated demand model, we propose a moving planning window heuristic to construct a promotion policy. Our heuristic promotion policy consists of shorter and more frequent promotions. We show that the proposed policy can increase the app lifetime revenue by around 10%.

The basic topic of This research is to evaluate, from the professionals'' point of view, the effectively of the operational auditing in instilling confidence on the report of the external auditor. It also presents a Field study on a sample drawn from the board of governors of the accounts. To achieve This point, the research depends on the employment of a theoretical model which includes a number of indicators that would be invoked in the Field study. These indicators are linked to the extent of the clarity and comprehensiveness of the approach in supporting the credibility of the report of the external auditor. To achieve thèse objectives, the researchers suggested the following assumptions: -The basic assumption: - The operational auditing participates in supporting the credibility of the external auditor reports. -The minor assumptions: 1-The operational auditing is a modern concept which expanded to include the measurement of the quality and effectiveness and performance évaluation, which Will contribute to establish the credibility of the report of the External Auditor. 2- There is an impact of the operational auditing in reducing the risks to give greater credibility to the report of the External Auditor. The researchers found the following results: 1- The study asserts that the expansion of the operational auditing to include the measurement of the effectively and performance évaluation contribute in instilling credibility on the report of the external auditor. The study also proved, through the practical analysis, that the expansion in this type of auditing contribute and adds credibility on the report of the external auditor and this point asserts the achievement of the first assumption. 2- The study also proved that there is a relationship between the operational auditing and reducing the risks to increase the credibility of the report of the external auditor. This point asserts the achievement of the second assumption. 3-The study also asserted the relationship between the operational auditing and achieving the credibility of the report of the external auditor.
