This study explores how the usability of digital wallets affects the growth of e-commerce in poultry shops in the Huancayo district of Peru. The general hypothesis states that the usability of digital wallets significantly impacts the growth of e-commerce in this sector. The methodology used combines the general scientific method with the specific hypothetical-deductive method. A non-experimental and cross-sectional design is used. The research is explanatory in nature, seeking to establish causal relationships between variables. To collect data, a survey was conducted on a probability sample of 385 customers in 112 poultry shops in Huancayo that use digital wallets. The sampling technique was simple random, and data were collected using an attitude scale designed to measure user attitudes and opinions. Results: The usability of digital wallets positively impacts e-commerce, with a correlation coefficient of 0.76 (p < 0.01), indicating a strong and significant relationship. The effectiveness of digital wallets in e-commerce growth is evidenced by a regression coefficient of 0.68 (p < 0.01), suggesting a significant effect on online sales. The efficiency of digital wallets shows a coefficient of 0.62 (p < 0.05), indicating a notable improvement in transaction time and payment accuracy. Customer satisfaction with digital wallets has a coefficient of 0.74 (p < 0.01), reflecting an overall positive experience with these payment tools.

This paper formulates robust optimization models for the problem of finding near-optimal locations for new intermodal terminals and their capacities for a railroad company, which operates an intermodal network in a competitive environment with uncertain demands. To solve the robust models, a Simulated Annealing (SA) algorithm is developed. Experimental results indicate that the SA solutions (i.e. objective function values) were comparable to those obtained using GAMS, but the SA algorithm could obtain solutions faster and could solve much larger problems. In addition, the results verify that solutions obtained from the robust models were more effective in dealing with uncertain demand scenarios.

This paper presents an empirical investigation on the effect of product market competition on transactions with related parties and company performance. The study selects a sample of 250 randomly selected firms whose common shares were traded on Tehran Stock Exchange. The study uses Herfindahl-Hirschman Index (HHI) to measure the market concentration and uses historical information over the period 2008-2012 to examine the hypotheses of the survey. Using simple regression analysis, the study has detected a positive relationship between HHI and related party transactions. In addition, the study has detected a negative relationship between competition and company performance measured by return on assets.

The Project Portfolio Selection is a complex process that involves many factors and considerations since the project is proposed until the project portfolio is finally selected. Project Portfolio Management is the iterative process of assessment, selection and implementation of projects, and the most important part of that is to select projects for portfolio where the or-ganization is required to identify and prioritize projects with the most objective alignment to its objectives. Since the selection of a suitable projects is very important, it is necessary to develop mathematical models to lead the organization towards the final goal. To achieve this goal, these models should reflect the organization's position, goals and priorities as much as possible. In this paper, we propose a multi - objective model for selecting the project portfolio that maximizes efficiency, quality while minimizes the risk involved in project execution.

The recent trend on competition among insurance firms has increased motivation to look for important factors influencing this industry. In this paper, we present an empirical investigation to find important factors shaping this industry. The proposed study designs a questionnaire in Likert scale and, using principal component analysis, detects important factors on the success of this industry. Cronbach alpha is calculated as 0.849, and Kaiser-Meyer-Olkin and Bartlett & apos; s Test are calculated as 0.873 and 12744 with (Sig. =0.000), respectively. The study has detected four important factors including quality of service casualties, sales improvement and advertisement, quality of issuance of insurance policies and quality of work force.

This paper presents an empirical investigation to study the effect of internet in insurance industry in Iran. The proposed study designs a questionnaire, distributes it among some experts and analyzes them based on some statistical test. The survey is conducted within insurance firms located in one of provinces of Iran. The results of the study confirm that internet influences competition among providers, bargaining power of customers as well as suppliers, significantly. In addition, internet has meaningful impacts on starting a business, the threat of substitutes, customer satisfaction, perceived image as well as perceived quality. The results of this survey emphasizes on the relative importance of internet for building a better competitive insurance industry.

The primary objective of this paper is to detect important factors, which are influencing competitive advantage. The proposed model of this paper uses sampling technique to measure characteristics of society. There are eight independent variables for the proposed study of this paper including packaging endurance, easy distribution, customer promotion through packaging, packaging structure, packaging as silent advertiser, diversity of packaging, clean and healthy packaging and innovation in packaging. The proposed study uses structural equation modeling to either accept or reject all hypotheses associated with the proposed study of this paper. The population of this study includes all managers and experts who are involved in packaging products. We used simple sampling technique and chooses 300 from a population of 450 people who are considered as the population of this survey. Cronbach alpha was determined as 0.732, which is above the minimum acceptable level. The results confirm that all mentioned factors influence competitiveness, effectively.

In recent years, development of freight transport industry has led to fierce competition among transportation companies and therefore carrier-pricing issue has received more attention by researchers. This paper studies pricing and fleet management decisions for full-truckload freight carriers, which compete on a road network. We propose a game theory approach under two scenarios. In the first, we model the non-cooperative game wherein the carriers announce their prices simultaneously in competition; in the second, we allow the carriers to share their information and announce their prices while participating in cooperation. We show that carriers can reach the highest profit level in the latter scenario; subsequently, a bargaining game is discussed as a scheme to share the extra joint profit.

Empowering workers play an essential role on increasing productivity in any organization. The service industries such as insurance companies or banks mostly rely on their own people to retain their customers and incomes. The recent increasing trend on the number of private banks in Iran has increased competition among existing banks. The banking industry strives to empower its employees as much as possible in an attempt to maintain market share by not losing its customers. In this paper, we present an empirical study to detect the most important factors empowering bank employees. The study is implemented for a recently established private bank with 228 people with 32 questions where 15 questions are focused on empowering employees. The results are analyzed using statistical tests and descriptive methods. The results indicate that leadership, academic qualification, appropriate policy and strategy, cooperation and processes play important role on empowering and enabling bank & apos; s employee.

Spirituality and ethics play important roles in bringing justice for many business units. During the past few years, there has been growing concern on thinking about profitability without considering other aspects such as spirituality. The infamous Enron incident has been a crystal clear of a case of thinking just on short-term profitability without considering other ethical issues. Spirituality helps organizations create ethical values, responsibility and job satisfaction among workers and these issues could increase business competitive advantages. In this paper, we study the impact of spirituality on different levels of individual, workspace and organizational for a real-world case study. The survey results of this paper indicate that spirituality could significantly impact the organization in different levels.
