This study aims to determine the construct validity of the Multi-dimensional Transformational Training Programs Scale in private universities in the Jordanian capital, Amman. The study involves a quantitative investigative approach via a questionnaire-based survey of all employees in private Jordanian universities in Amman. A total of 212 valid questionnaire was finally obtained. Exploratory and confirmatory factor analysis was using to evaluate construct validity. The study reveals that the Transformational Training Programs constructs consisting of multiple factors confirmed that the rating for 13 items was above 0.50. The study provides practical evidence for the testable scales that are both reliable and valid, giving a new practical insight into the Transformational Training Programs. Transformational Training Programs dimensions cover most of the Initiatives used by organizations, which will affect the levels of excellence superiority in the long term.

Previous researches have claimed that visual programming environments are helpful for learning programming by problem-solving. The purpose of this work is to use a blockly visual programming educational game for university students and analyze their sequential learning behaviors. The study presented a two-level sequential pattern mining algorithm to mine the students' behavioral patterns.

Halo event of coronal mass ejections (CMEs) had been once in a while reported in coronagraph observations of the Sun before the Solar and Heliospheric Observatory (SOHO) mission has been carried out. However, since mid-1996 the SOHO Large Angle Spectrometric Coronagraph (LASCO) instruments have observed numerous halo or partial-halo CMEs. Partial halo is when CMEs aimed at Earth which is called as "halo events" because of the way they look in coronagraph images. As the expanding cloud of an Earth-directed CME becomes larger and it appears to envelop the Sun, forming a halo around our star. Statistical interpretation states that most of the halos CMEs occur at average speed of ~957 km/s. In 2015, eight (8) halo CMEs events were detected accompanied by slow partial halo CMEs. Sunspot number, solar radio flux and solar wind involves in interpreting the slow movements of halo CMEs. In this paper, we study partial halo CME events with slow velocity and we discussed the slow partial halo CMEs which is due to the weak magnetic fields affect from low solar radio flux and solar wind fluctuation. The slow halo CME events were observed through CALLISTO System and compare it with database from CACTUS. As a result, we found that there are slow halo CMEs occur with velocity as low as 100- 200km/s.

Assuming that all projects commence at the beginning of the investment horizon，and have different durations. The profit generated by the completed projects can be reinvested in the other projects, the capital surplus can be used for securities investment and adjustment after project investment. To help the investors obtain higher investment return than traditional pure project selection method, we transform the proposed bi-objective function into a single objective function, and propose a mixed project and security selection and adjustment model. Then provide a stochastic simulation based solution method to solve the problem.

The aim of this study is to determine the reliability and validity of a new scale for measuring vocational knowledge towards entrepreneurship. The reliability will be examined using the Cronbach alpha. A fixed Cronbach alpha scale of 0.7 was used as the standard scale. The study also examined constructive validity, convergent validity and the divergent validity using the exploratory factor analysis. The study consisted of 631 participants from five colleges in Northern Saudi Arabia. The study indicated that the new scale for vocational knowledge have a convergent validity as it was able to examine the degree to which the operationalization is similar to other operationalization that it theoretically should be similar. The study also indicated that the questionnaire is reliable and is able to give reliable and consistent results to the study.

In this study we propose a proactive optimization approach to manage the supply chain risk. The purpose of presented model in this paper is supplier selection with the objective of minimizing the total cost. We apply the multi sourcing strategy to avoid the supply disruption while restricting the selection by suppliers' corporate groups and the second-tier suppliers. We examine the model by different datasets. The findings suggest that this approach has more fficiency when the variance between suppliers' total cost is lower.

Convex Nonparametric Least Squares (CNLSs) is a nonparametric regression technique to estimate monotonic increasing and convex functions. In addition, CNLS method builds on the same axioms as Data Envelopment Analysis (DEA) and also takes into account noise. This paper is to investigate the use of convex least square regression to represent a fuzzy DEA model. By the results of CNLS, we can repeatedly use the corresponding fuzzy DEA model to assess the performance of unobserved decision making units. Note that DEA results cannot be repeatedly used as the regression results for unobserved entities. The popularity of fuzzy DEA would be enhanced.

Recently, the user-orientated design used in product/service innovative process has been received considerable attention from both academia and industry. Products considering the user-orientated design are able to meet the users' needs more effectively. Conventionally, the user-oriented design method adopts the sticky note to document the inconvenient experiences from brainstorming or observation when users use the produce/service. The results of diverging and converging user's needs are presented in the form of placard. However, this method is not conducive to the reuse of information and knowledge. In addition, the results cannot be shared with design team that did not involve in the process so that creative ideals cannot be systematically recorded as database to provide future innovative design. This study proposes a web-based product innovative design platform, which utilizes user-oriented design with the user-friendliness aspect, to effectively support the information management system of firms. In this study, the focus team is considered in collecting and converging the required and desired functions from the results of innovative product/service design, including creative note and user requirements analysis. Then, a unified modeling language is used to describe and analyze the platform's requirement. This is followed by using FLASH to stimulate user-friendliness of the platform. Finally, a real case of a large-scale Taiwanese furniture firm researching new bed model is used to illustrate the applicability of the proposed platform.

To Taiwan for example, because the land is not easy, the cost of rent is expensive, so take into account the need for goods distribution process to the logistics center as a relay station. This study explores that when the vehicle returns to the logistics center and then arrives at the demand point, the pick up and delivery separately; When the vehicle goes to the supplier to accept goods directly don't through distribution center deliver goods to the need point, the pick up and delivery together. Assuming the delivery process (to discuss the first to send and receive, send and receive goods together) whether the transit to the logistics center whether the impact of delivery speed, distribution of vehicles and distribution distance.

A unique phenomenon in the retailer market nowadays, where some of the retailers (salvage retailers) buy nearly expired grocery products from other retailers and resell them, may lead to the better market segmentation and increase the utilities of both consumer and retailers. This paper aims to model the possible relationship (i.e., decentralized and centralized system) between retailer and salvage retailer. EOQ model with demand as a multivariate function of product price, freshness level, and displayed inventory level is used. Zero ending inventory assumption inventory is also relaxed to boost the sale and profit based on the demand formulation. As a result, the objective is to determine three decision variables (i.e., product price, inventory cycle time, and ending inventory level) in order to maximize the total profit. Numerical examples are presented to highlight the theoretical implications and managerial insight.
