Households Drinking Water Sources and Treatment Methods Options in a Regional Irrigation Scheme
Authors: Kerich Emmy C. 
Published: November 2021

Access to safe and clean drinking water is a major challenge to the people living around Ahero Irrigation Scheme (AIS). Water sources in the area are constantly and increasingly polluted by agrochemical like pesticides from rice farming. 2, 4-Dichlorophenoxyacetic acid (2,4-D) is an herbicide extensively used in AIS. The neurotoxic, immunosuppressive, cytotoxic and hepatoxic effects of (2,4-D) have been well documented. Residues of (2,4-D) have been documented in ponds, rivers, lakes and irrigation canals. Therefore this study surveyed agrochemicals used in AIS, the drinking water source for the residents and finally water treatment option for the obtained water in the year 2013. The study established that (52.8%) of the farmers used hand-weeding and 20.8% of them use (2,4-D) for the weeds control. Results indicated that the most preferred water source was lined improved well (47.2%) followed by irrigation canal (22.2%), the least preferred was rain water with (2.8%). The most used method of water treatment was chlorination (45.8%). Spearman’s coefficient of correlation ( ) revealed that there was positive correlation between the two variables ( =0.145, 72, p=0.224>0.05). As is positive, it implies that the type of treatment given to water depend on its source of the water. Despite the use of chlorinate with almost half of the residents, some of them (22.2%) do not treat their water at all, which may pose a risk of getting water related diseases. Furthermore, despite a proportional number of residents obtaining their water from irrigation canal, all of them do not have appropriate method/s for treating water contaminated with organic pollutants such as herbicides. There is a need to promote water appropriate drinking water treatment method/s in the study area to prevent water related diseases at the family level. Doi: 10.28991/HEF-2020-01-01-02 Full Text: PDF
Assessing Decentralized Contract Life Cycle Management Issues and Challenges
Authors: Ampumuza Gracious Jean , Okaka Wilson , Obanda Peter W. , Watmon Titus Bitek 
Published: November 2021

This article examines the influence of contract life cycle management on procurement performance of Local Governments in Uganda using Bugiri District as the case study. The three specific objectives of this study were to: examine the influence of contract creation on procurement performance; to assess the influence of contract execution on procurement performance and lastly, to determine the influence of contract analysis on procurement performance. The researcher employed a descriptive case study research design. Using a researcher’s made five point Likert scale questionnaire, data was collected from a sample of respondents. Seventy (70) respondents out of a population of eighty (80) were selected using purposive and random sampling techniques (response rate of 94.3%). Data was analyzed using means and the regression analysis. Findings revealed that; the extent to which contract creation predicts performance was low (r2 = 0.36, Sig. Value= 0.000); the extent to which contract execution influences procurement performance was low (r2 = 0.34, Sig. Value = 0.003) and lastly, the extent to which contract analysis influences procurement performance was moderate (r2 =0.44, Sig. Value = 0.001). On the other hand, findings revealed that contract management at Bugiri District local government in Uganda highly and positively influences procurement performance (R2= 0.779 Sig. Value= 0.000). This implies that where each of these variables; contract creation, execution and analysis are handled separately, each has a low influence on procurement performance. However if handled wholesomely, results show that high procurement performance (78%) will be achieved. In light of this, the researcher therefore concludes that; practioneers, managers and civil servants at Bugiri District should adopt a holistic approach in contract management, if procurement performance is to be maximized.

Authors: Yamini Omid Aminoroayaie , Kavianpour Mohammad Reza , Movahedi Azin 
Published: November 2021

Flip buckets are usually used in high head dams to dissipate the destructive energy of high speed jets. These structures are fixes at the end of the outlet conduits to direct the moving jet into the atmosphere. The process of energy dissipation also resumes, while the jet entering into its downstream plunge pool. Although studies of flow over flip buckets turn back to many years ago, but still there are uncertainties regarding the flow behaviour over these structures with various geometries and flow conditions. In this study, experimental measurements of static and dynamic pressures and their distribution over these structures are investigated. Measurements were made along two different simple flip buckets with various Froude numbers to determine the effects of the geometry and flow characteristics on pressure field. Maximum pressures are also presented and the results are compared with those of other investigations. The results of this study can be used to increase the safety of large dams that remain sustainable in the process of exploitation such as irrigation, human consumption, industrial use, aquaculture, and navigability.

Community-driven Development Strategy for Sustainable Infrastructure
Authors: Ezirim Onyekwere N. , Okpoechi Chinwe U. 
Published: November 2021

Many border communities are far from city centers and obscured from the mainstream of development. This can foster environments where insecurity, criminality and certain anti-state activities thrive unabated, thereby posing a real danger to the sovereignty of the Nigerian State. Akamkpa Local Government Area in Cross River State is one of such border territories. This research studied the border communities in Akamkpa local government area to assess the contributions of government driven infrastructure intervention projects in the development of the communities. The study is aimed at evolving an appropriate strategy for integrating border communities into the mainstream of development in Nigeria. Four border villages closest to the Cameroon border with Nigeria were chosen for the study through purposive sampling. The primary source of data collection was through a questionnaire survey, which was administered randomly to forty household heads in the communities studied. Analysis of data was by a combination of simple descriptive statistics and inferential statistics. The findings of the study showed that provision of basic infrastructure and services in the study area have remained grossly deficient, notwithstanding the government infrastructure intervention policy currently in place. The results of the survey further showed that the residents would like to have a say in infrastructure planning and delivery in their communities, which is presently not the case. The study concludes by proposing a strategy of community participation in a sustained regime of infrastructure and services provision by relevant agencies. This is believed to have the potential to positively impact their livelihoods, improve security and integrity of the borders, and create the right atmosphere for patriotism to thrive.

Pushing the Limits using Business Model Innovation a Three Pronged Approach and Lessons Learned
Authors: Motjolopane Ignitia 
Published: November 2021

In a constantly changing business environment, with increasing digitisation and fourth industrial revolution blurring the traditional value creation boundaries, companies need to explore ways to push the limits to remain competitive. Business model innovation offers companies the dynamic capability to differentiate business models and find innovative revenue streams while reducing costs. As such, the question arises as to how company may use business model innovation to remain competitive as the world digitises. Based on a literature review and empirical research involving six case studies, a three pronged approach in support of business model innovation is proposed. Business model innovation has the potential to push the limits when company executives and academia focus on the interrelation between drivers, process and components. Moreover, both effective and ineffective practices based on the research are presented. In conclusion, for companies to use business model innovation in pushing the limits, there is need to respond to the business model innovation drivers, adopt a systematic process and change at least one or more business model components and taking into account the interactions between these three concepts. This article may contribute to existing theory in the field of business model innovation and lessons learned from executives that have pushed the limits using business model innovation.

COVID-19: A Game-changer to Equity Markets?
Authors: Golmohammadi Saeed , Fazelabdolabadi Babak 
Published: November 2021

This article applies the effective transfer entropy methodology to quantify the information flow between equities in major global equity markets in Australia, Brazil, Canada, China, Germany, Iran, Japan, Qatar, Saudi Arabia, South Africa, South Korea, United Kingdom, and the United States – a pool of 2200 companies included. To account for COVID-19 impacts, the period of the study was extended over two years. The results show changes to the information flow pattern after COVID-19, with the largest changes being encountered in Australia, Brazil, Canada, Japan, and the United States – for their largest market participants (by market capitalization). In comparison, the Asian markets show less noticeable changes in their information flow pattern after COVID-19. On a sector level, most of the markets studied have seen substantial changes in the functionality of their sectors – in terms of being a transmitter or receiver of information – after COVID-19 appearance. The fraction of sectors with a complete change in their influencing role since COVID-19 has been over 70% in Australia, Canada, South Africa, and the United States. The financial services sector has retained its role - as being the most influencing sector - in 6 out of 13 markets considered after COVID-19. For most of the markets, the basic materials, communications, energy, and utilities sectors have retained an intermediate position in the information flow diagram, after COVID-19. The German market has been the only market, in which the main information transmitter and receiver sectors have remained unchanged, since COVID-19. The results suggest drastic moves in major global equity markets, which have been concurrent with the virus outbreak. Doi: 10.28991/HEF-2021-02-01-05 Full Text: PDF

Automation of Collection of Primary Data for Development of a Passenger Origin-Destination Trip Correspondence Matrix Based on Computer Vision and Neural Network Technologies
Authors: Postolit A. V. 
Published: November 2021

The origin-destination trip matrix is a fundamental characteristic of a transport network, and development of a reliable correspondence matrix is the most important task in organising passenger traffic. It is the basis on which the public transport route network of a city (region) is built and optimised.Currently, collection of initial information for construction of a travel correspondence matrix is carried out through field surveys comprising questionnaire surveys of the population; accounting for movement of passengers according to the coupons issued to them; checkers, tellers manually counting passengers in vehicle compartments; simple surveys of passengers. Besides, mathematical modelling is used based on statistical data on the number of residents in various districts of the city, employees in enterprises and students in educational institutions, as well as on available data on the characteristics of passenger traffic along certain routes. All these surveys are very expensive and are carried out once over few years; they give a large error, which is why decisions made on the basis of these data are far from being optimal.There are a lot of solutions in the software and hardware market that provide automated collection of data on passenger flows. They are based on the use of infrared sensors or of video recording. However, none of these systems provide information about the points of entry and exit of each passenger. The objective of this study was to develop methods for automating the collection of reliable information about passenger trips, that will be the base for building up-to-date and reliable passenger trip correspondence matrices. This task can be solved by constant monitoring of passengers’ trips with fixing places of entry and exit of each passenger.The study describes the possibility of creating software based on computer vision and artificial intelligence which will provide automation of collection of primary information about travel of each passenger from the place of boarding into the vehicle to exit from it, that is, automation of data generation to build a passenger trip correspondence matrix.

Published: November 2021

Base station (BS) is a terminal device of a radio communication network, while railway radio communications play an important role in ensuring safety of passenger and cargo transportation.A proposed method for calculating the performance of base stations in railway digital radio communication networks is intended to calculate for the BS the probabilities of being in certain state.BS was decomposed and such functional elements as circuit groups and a radio frequency path were identified, as well as the central module ensuring the exchange of information with elements of this BS and with other BSs. A detailed study of each element has increased accuracy of the proposed method. Following the Markov model, BS is presented as a system in which all possible states are considered. Models for BS with two and three circuit groups have been constructed. The parameters of each functional element of the model can be obtained through observation over a certain period. The solution of the system of equations for each of the models presented in the article will allow obtaining the values of the system being in a certain state. The obtained characteristics can be used to calculate the reliability of the entire radio communication network, and then to assess quality of service provided to the users of this network.Conclusions are made about the possibilities of using the obtained models when designing new railway communication networks and when calculating quality indices of existing ones. The proposed models can be applied not only to railway radio communication networks but also to mobile communication networks of commercial operators.
