The Impact

This paper analyzes the influence of the factors belonging to the Logistics Performance Index (LPI) on the competitiveness of Logistics Enterprises (LEs) in the Mekong Delta (MD), Vietnam. The input factors will be selected from a rigorous document review process combined with an in-depth survey of leading experts in the logistics field. Since then, an integrated approach including Improved Descriptive Statistics (IDS) combined with Fuzzy Interpretive Structure Modeling (FISM) has been structured to achieve this purpose. Specifically, the factors that have the closest relationship with competitiveness will be determined from the results of an improved descriptive statistical method, then the results will be developed using the FISM method under trapezoidal fuzzy number format to realize the importance of factors contributing to improving the competitiveness of logistics companies. The results have shown the impact of 16 sub-factors, which belong in the 4 main factors of Reputation (REP); Timeliness (TIM); Customs (CUS); and Ease of arranging shipments (EAS), on the competitiveness of logistics enterprises in the region analyzed in 4 clusters (Dependency, Association, Autonomy and independence). In which, 6 out of 16 factors have a significant impact on competitiveness that logistics enterprises need to pay more attention to in their operations. These factors will be ranked as REP4, REP 5, REP3, REP1, REP2, EAS1, respectively.

Various environmental and economic aspects of urban water and wastewater crises in a number of the Arabian Gulf States are discussed. An integrated approach, which considers simultaneously the problems of urban waters (shortage of water supply and problems associated with urban drainage) and those in connection with wastewater (i.e. environmental impact) is proposed. The feasible link between the main factors affecting these problems and the anticipated results encourage the implementation of the proposed approach. The conclusions suggest immediate municipal legislation.

The Impact

Blood flow has been extensively studied because of its close relationship with cardiovascular disease. Heart valves blood flow analysis is particularly complex due to the high mobility of its leaflets, a fact that has stimulated the development of computational models aimed to its better understanding. For studying heart valves blood flow, we developed a mathematical model derived from clinical observations based on echocardiographic images, which describe valve leaflets motion and its influence on blood flow. This work presents a concentrated-parameters-based model of heart valves blood flow that takes into consideration five main factors affecting such a flow in the mitral and aortic valves. This model considers factors that are related to blood fluid and valve leaflets characteristics. Considering the main factors involved, it was found that blood flow exhibit an abnormal behavior in response to small variations (less than 10%) in blood pressure gradient or in leaflets stiffness. Likewise, after changing the roughness of the leaflets, the impact is smaller, only slightly affecting blood flow behavior with changes beyond 30%. Moreover, it was observed that the influence of fluid vortices originated behind the valves can be disregarded and the kinetic energy induced by them is almost negligible.

Routine health checkup is the simplest and most scientific method for early detection, minimizing harm, and preventing complications of diseases. However, until now, only a fraction of the population is aware of its importance. Studies in the world and in Vietnam show that the proportion of the population having routine health checkups remains modest. Understanding which factors affect the decision to have routine health checkups is important in creating a system and environment that encourage people to have regular health checkups. The study is based on the survey data of 420 people in Khanh Hoa province to identify the main factors affecting their decision of routine health checkups, using the Logit regression model. The results shows that factors affecting decisions on routine health checkups include: education level, occupation, income, age, chronic illness, waiting time, and the impact of cost. The study also determines that gender and marital status have no effect on regular health checkups. The results highlight the importance of taking into consideration the priorities of time and cost when developing policies to encourage regular health checkups in the population.

The vehicle color is considered to be a significant factor affecting driver visibility. The primary objective of this study is therefore to determine the impact of black-and-white striped vehicles (BWVs) on driver visibility through simulation-based experiments. In these experiments, subjects were asked to perform front and rear target identification tasks under daylight and twilight conditions. Then, a 2 (lighting conditions) × 2 (vehicle size) × 5 (vehicle color) analysis of variance was conducted for each task. Under the front identification scenario, the main factors affecting visibility were found to be lighting conditions, vehicle size, vehicle color, and the interactions between these factors. Under the rear identification scenario, lighting conditions and vehicle color were found to be the main factors. The results of this study demonstrate that driver visibility of BWVs is poorer than that of other colors of vehicles and that BWV visibility is susceptible to lighting conditions.

Structural Shifts

The article analyzes the dynamics and provides a forecast for 2021 of the yield of grain and leguminous crops in Russia. According to the results of the analysis for the period from 2006 to 2019, the average annual increase in yield by 0.6 center per ha was revealed for all categories of farms. The average grain yield in the forecast year will be in the range of 26.5 to 29.6 center per ha. The main focus of this article is on the assessment of the impact of structural shifts in sown areas on the yield of cereals and legumes. According to the results of the index method, it was found that due to changes in the regional structure of grain crops, the yield in Russia as a whole increased by an average of 5%. Based on the constructed regression model, it is concluded that the main factors affecting the grain yield are the productivity of the climate and the number of mineral fertilizers applied.

Document Review

The study sought to determine the role that the National Archives of Namibia plays in the management of audio visuals in an attempt to curtail the deterioration of audio-visual archives which are kept in various organisations, some of which are unknown to the National Archives of Namibia. A qualitative method was applied in the study. The case study used the interpretive paradigm which enabled the researcher to triangulate the data collection instruments. Interviews, questionnaires and observation checklists were used to collect data. Content analysis was carried out to analyse data from interviews, document review and the observations. While Excel software provided descriptive statistics on graphs. The results indicated that AV materials were created and stored by various organisations, including the National Archives of Namibia, which oversees the management of all records. The Archives Act (Act 12 of 1992), section 4(1), gives a mandate to the National Archives of Namibia for control over records and archives of all formats in government offices, offices of local authorities and statutory institutions. Nonetheless, there are instances where AV materials are not deposited or stored in appropriate conditions. It is also apparent that different cataloguing and classification systems are used by different organisations. It is clear that most of the organisations manage AV materials in the same way as paper formats records. There is also an inadequately skilled workforce who were given a responsibility to manage AV materials. The study was limited to the Khomas region. Since there are 14 regions in Namibia, the findings cannot be generalized to other regions. Future studies should cover other regions. The results point to the need for the National Archives of Namibia to adopt an integrated approach to the management of AV records. This will require the NAN to work in cooperation with public sector institutions and empower them to preserve AV materials while, at the same time, they continue to deposit copies with the National Archives of Namibia. Unlike previous studies on management of audio visual archives in Namibia, this study included other organisations. The results give a clear picture of the role the National Archives plays in the management of audio visual records and archives.

The Impact

The objective of the present review was to establish levels of conserved fodder wastage when feeding livestock (sheep, beef cattle, dairy cattle) under various conditions and using various feed-out systems, and to determine the factors affecting wastage. The mean wastage of hay recorded in the literature reviewed was 17% of the DM offered, but the range was from 4 to 77%. The main factors affecting the degree of wastage were storage method, packaging method, method of feeding out, amount of fodder on offer and its palatability and/or quality and the impact of wet weather. Although the emphasis was on hay, the principles should also apply to silage. If wastage was 40% rather than 5%, the cost of feeding conserved fodder to livestock would be a third greater than producers might expect or budget on.

The Impact

Nitrogen losses from utilised agricultural areas are responsible for water quality degradation and eutrophication. Denitrifying bioreactors can be used to reduce high nitrate concentrations in agricultural runoff in situ. The main factors affecting their function are the bioreactor fill medium and process parameters such as hydraulic retention time, temperature and inlet concentration of nitrates. The paper presents the results of laboratory experiments achieved with bioreactors filled with eight different wood-based materials, namely mulch, a mixture of spruce and pine sawdust, a mixture of pine and larch bark, and chips made of oak, poplar, larch, beech, and spruce wood. A sustainability index was used to assess the impact of the bioreactor on the environment. The best results were shown by beech, mulch and poplar and were achieved with hydraulic retention times 1.6–0.7–2.2 days, respectively, and inlet NO<sub>3</sub><sup>–</sup>-N concentration of 43.1 mg/L.
