Purpose: The main purpose of the study was to determine the influence of backward vertical integration strategies on the competitiveness of firms in the Export Processing Zones (EPZ), Kenya.

Methodology: Both quantitative and qualitative approaches were used in this study, meaning that both descriptive statistics and inferential statistics were employed. Descriptive technique, specifically survey was used in the research design. The target population was all the 137 EPZ firms within Kenya and the sample was drawn from this population. The stratified random sampling technique was used. The EPZ firms are situated within the 74 gazetted zones, out of which 69 are privately owned and operated while 5 are public zones. The quantitative data that was collected was analyzed using the Statistical Package for Social Scientists. Further, the significance level of each independent variable was tested against the dependent variable at 95% level of confidence using ANOVA, regression and correlation techniques. 

Findings: The findings showed that backward vertical integration strategies had a positive and significant influence on the competitiveness of firms in EPZ, Kenya, at 0.151, p<0.05 and 0.432, p<0.05 when the moderating variable firm size is included.

Unique Contribution to Theory, Practice and Policy: This study contributes to both the resource-based view and the theory of dynamic capabilities. It lays emphasis on the importance of resources in attaining competitiveness as suggested in these theories. Besides, the study emphasizes the need for firms to have policies aimed at ensuring raw materials supply stability, lower transaction costs and enhanced economies of scale. The findings of this study are significant because the Government of Kenya envisages that the EPZ program is expected to play a critical role in the manufacturing sector contributing 20% to Gross Domestic Product (GDP) by 2030.  This will subsequently lead to an increase in employment opportunities, real-value added growth, and foreign direct investment (KNBS, 2022). The study recommends a review by the EPZ Authority in Kenya , of the underlying aim of using backward vertical integration strategies as means of gaining competitive advantage competitiveness and the inclusion of this strategy in the various EPZ  firm’s policies and procedures.

Authors: Cho Woohyun
Published: February 2024

How can we protect the rights and interests of nurses? This question led the National Assembly of the Republic of Korea to propose the Nursing Act that has been praised and condemned. The bill has honorable goals: to promote the rights and interests of nurses. Opponents view the act as "a law only for nurses," criticizing the potential for the act to benefit nurses only at the expense of other healthcare professionals. This paper reviews the provisions of the Nursing Act and analyzes the arguments used by both sides in the legal context of the Constitution and the Medical Service Act. This result reveals that the pro-Nursing Act constituency leverages more valid pieces of evidence than the opposition.

Solution of logistic differential equation in an uncertain environment using neutrosophic numbers
Authors: Parikh Meghna , Sahni Manoj
Published: February 2024

The modeling and forecasting of population dynamics, as well as growth in biological systems more generally, have required the construction of various growth models. This paper presents the logistic growth model, which is a modified version of the exponential growth model and offers a more flexible framework to capture fluctuations and potential deviations from deterministic predictions. This paper aims to advance the model of a logistic growth differential equation within a neutrosophic environment, with a focus on validating the proposed framework by applying it to predict the projected population of India from the year 2001 to 2050. We investigated the neutrosophic solutions and validated them with the exact solution with available projected data on the portal of UNITED NATION. The developed logistic growth differential equation in a neutrosophic environment is visually elucidated through graphical representation, enhancing the clarity and accessibility of the presented model.

Authors: Miss.SnehalPagare  , Mr. Pratik Shardul  , Miss. Neha Thakur  , Mr. Shreyash Jadhav  , Mr. Siddesh Malve
Published: February 2024

The increasing popularity of expert system applications is undeniable. Computer technology evolution has significantly impacted various domains, including environmental security.Onenotable advancement is the elimination of manual attendance procedures, which were not only time-consuming but also prone to providing inaccurate results. The introduction of automated time and attendance monitoring systems has brought numerous benefits to organizations. These systems reduce reliance on pen-and-paper-based manual attendance tracking.
In alignment with this shift, we have introduced an attendance system based on location, utilizing global positioning (GPS) technology. This system operates through a mobile application on smartphones, leveraging the GPS capability to determine the device's location. The location data serves as a key component in the time and attendance tracking process, eliminating the need for traditional manual methods. To achieve this, we employ the Geospatial technique, determining whether the student's location falls within the designated Geospatial locality.
Our innovative project extends beyond attendance tracking and introduces a Child Tracking System within a dedicated application. This feature empowers parents to monitor their child's cell phone activities comprehensively. Parents can oversee incoming and outgoing calls, text messages, and multimedia messages. Additionally, they can track their children's whereabouts in real-time using GPS functionality and access a historical record of their locations. To enhance parental control, the system allows setting alerts for instances when children venture outside approved geographical ones
Investigating an alternative to exhumed grey cast iron water pipes for small-scale fatigue tests
Authors: John Edward D'Arcy Aston , Boxall Joby , Collins Richard , Bowman Elisabeth , Susmel Luca
Published: March 2024

Reducing and preventing leakage is a priority for water distribution network managers in many countries, including the UK. Understanding the mechanisms that cause leaks to form, and developing the ability to model these processes, will enable proactive replacement of water pipes before they start to leak. Smaller diameter Grey Cast Iron (GCI) water pipes are understood to experience biaxial, repeating loads, so fatigue cracking may be a cause of leakage for these pipes. To investigate this fatigue cracking mechanism a small-scale biaxial fatigue experiment is under development at The University of Sheffield. A large number of small diameter, un-corroded GCI pipes are needed to serve as specimens for this experiment. Therefore, in this work off-the-shelf BS416-2 DN 50 mm soil pipes are explored as an alternative to using exhumed pipes, which are often corroded and ≥76.2 mm diameter. The graphite microstructure and tensile stress-strain behaviour of a BS416-2 pipe were characterised and compared with literature data for exhumed spun-cast GCI water pipes, and a good agreement was found. This work concluded that BS 416-2 soil pipes can be used to represent spun-cast GCI water pipes in small-scale destructive experiments.
A Model of Intermittent Water Supply Simulating the Inequitable Distribution of Water
Authors: MacRorie Matthew Henry , Speight Vanessa L , Weston Sally L , Price Robin , Collins Richard P
Published: March 2024

Over one billion people worldwide with access to piped water experience Intermittent Water Supply (IWS), where consumers receive water for only a fraction of the day or week. A widely observed problem associated with IWS is the inequitable distribution of water across the network. This results in different consumers in the network receiving different volumes of water. Modelling the inequity within IWS systems remains an open research field. To date, simulations have often adapted hydraulic modelling software to understand the distribution of water with little attention to the consumer interaction with the network. This paper proposes a conceptual model based on a more holistic understanding of water distribution in IWS systems. Understanding the spatial and temporal variation in received volumes, as well as the variation in consumer access within the network, enables a more representative simulation of the inequitable quantity of water received by consumers.
COSMOS – A framework for containerised, distributed execution and analysis of hydraulic water distribution system models
Authors: Arbesser-Rastburg Georg , Camhy David , Fuchs-Hanusch Daniela
Published: March 2024

Many scientific problems related to water distribution systems like optimization problems or sensitivity analysis require the creation and execution of a large number of hydraulic models. To reduce computation times, different approaches have been used in the past, often by employing multiple CPU cores to solve the hydraulic equations of a single model or to simulate multiple models in parallel on a single computer. However, these approaches often cannot make use of distributed computing. Furthermore, using these approaches in applications with a (web-based) graphical user interface (GUI) often requires the development of tailored software solutions and application programming interfaces (API) to link GUI and model execution backend.To tackle these issues, we propose COSMOS (Containerised Model Simulator), a highly scalable Python-based framework which allows for the modification of hydraulic models using OOPNET, an API between Python and the hydraulic solver of the modelling software EPANET and can run model simulations. Simulation results can be then further analysed while all these tasks run encapsulated in containers in a cluster. It also allows to easily link the described functionality with other applications by providing a REST API.A standard-based OpenAPI allows for passing hydraulic models and running scientific workflows via HTTP and generating clients based on the provided OpenAPI schemas, which simplifies the creation of web-based user interfaces. Python was chosen because of its growing spread in the scientific community, the availability of data processing and optimization packages and its high code readability.Prefect, a data workflow orchestration framework, is employed to create workflows, starting with the transformation of hydraulic models into JSON representations for further use in web applications. The models can then be executed and simulated distributed over the available CPU cores (locally or in a cluster). Further tasks for doing analysis in the cluster can be easily added if necessary. Hydraulic models and simulation artifacts are stored on S3-compatible storage and can be easily retrieved.A main advantage of this approach is the use of containers, which allows for reproducible workflows. Compared to other high performance computing approaches and container-based systems, Prefect has the advantage of being able to keep dedicated worker nodes available for use. This comes in handy especially when dealing with relatively short computation times where the start of a container might take longer than the actual simulation. Additionally, simulation data post-processing can be easily added to workflows in Prefect. Furthermore, as the structure of COSMOS is highly scalable, it can be used for different levels of problem complexity and simulation runtimes.

To stop the spread of the COVID-19 pandemic, governments all over the world have applied social distancing measures, which have drastically altered people’s lifestyles. Many studies suggest that the water sector, including its demand and supply, has been strongly affected by these regulations. The importance of hygiene practices confers a crucial role to potable water availability as an ally for tackling the spread of the virus, heightening the alteration of water demand patterns during the ongoing pandemic. Therefore, this research aimed to assess the impact of the pandemic on the water consumption patterns in four Latin-American cities and the differences among the type of users. The case studies include two Colombian and two Mexican cities known for their important industrial and touristic features. The outcomes reveal a diminishing effect on water consumption for industrial and commercial customers. Touristic cities were the most affected, even experiencing decreased domestic water demand. Understanding these changes and challenges is essential for keeping and improving the resilience of water systems in different scenarios, especially under fluctuating environmental conditions.

Urban drainage network (UDN) is an important lifeline for urban areas, without which living conditions as we know it cannot be imagined. Internal and external pressures on these systems like structural failures, climate change and urbanization, require efficient modelling strategies for its management and maintenance. For proper functioning of the system as a whole, some elements of UDN infrastructure hold more importance than other elements. Identifying these critical elements in UDNs is of utmost importance for forming efficient management strategies. In this study, a graph-based method based on “runoff edge betweenness centrality” is presented for determining the critical elements (pipes) of a UDN. In contrast to conventional hydrodynamic modelling method, proposed graph-based method does not rely on iterative hydraulic simulations. Instead, it takes a mathematical graph representing the structure of the network as starting point and incorporates hydraulic factors to mimic the hydraulic behavior of UDN. Effect of loop degree on this graph-based method is studied by employing the method for a fully branched network, partially looped and fully looped network. A fully branched network is employed as a case study comprising of 59 circular pipes, draining an area of 175 hectares. Loops are manually created in the same network to study the impact of different number of loops on the accuracy of graph-based method. The results from the graph-based method are compared to the hydrodynamic modelling results from SWMM model in terms of accuracy as well as computational time and effort required. Results show that the graph-based method is very accurate (99%) in case of a fully branched network but the accuracy decreases with the increase of loop degree in the network. This is due to the complex hydrodynamic effects like back-water phenomenon which cannot yet be modelled using graph-based approach. The method is hence least accurate (93%) in case of fully looped network though still very useful, because the computational time and effort required is much less than hydrodynamic modelling method. The proposed method is also less data intensive as compared to HMM and hence can be used by utilities where quick analysis is required.

Acoustic sensors are widely used for monitoring urbanized water distribution networks (WDNs) to detect and localize pipe leakages. Since their inception, few research studies have focused on developing a generic, effective, and practical methodology to analyse complex acoustics signals for leakage detection and localization in large-scale WDNs. In collaboration with PUB, Singapore’s National Water Agency, a generic acoustic data analysis approach has been developed to facilitate PUB’s present Smart Water Grid (SWG) management. The proposed approach encompasses multi-stage systematic analyses, namely: (1) data quality assessment; (2) data pre-processing; (3) near real-time leakage event detection and classification; and finally (4) near real-time leakage localization. Our proposed approach is then tested in major WDNs in Singapore having more than 1100km of underground water pipelines and 82 permanently installed hydrophone acoustic sensors between 1 Aug 2019 and 31 Aug 2020, where multiple historical leakage events were reported to within 600m, or less, from neighbouring hydrophones across the large complex networks. By emulating the near real-time detection and localization analyses daily, our proposed methodology could localize reported leakage events to an error range of around 150m on average, while demonstrating significant and stable acoustic leakage power rate over the temporal size of the leakage event cluster(s).

Lack of access to drinking water mostly affects the sub-Saharan Africa. In Kenya, since 2000, access to safe drinking water has increased by 12 per cent, while access to basic sanitation has fallen by five per cent. The Italian NGO LVIA – Lay Volunteers International Association – has been working in Kenya for more than 50 years to improve living conditions of the beneficiary populations, also with interventions in the water sector that contribute to the achievement of the No.6 Sustainable Development Goals (SDGs) which aims to ensure the availability and sustainable management of water and sanitation. Since 2012, several international cooperation projects have been carried out in collaboration with the pastoral communities of the rural areas of the Isiolo County. Isiolo County, located in Northern Kenya, has been plagued for years by severe droughts and floods that put a strain on water access and the already precarious water infrastructure. In this study, we present the rehabilitation of water supply systems in the villages of Duse, Bulesa/Godha, Sericho, Gafarsa, Oldonyiro, Kipsing, Kinna affected by floods at the end of 2019. In addition, the rehabilitation of Boji village water supply system will be described, as an example of good practise for implementing small community water supplies. In particular, the construction of water kiosks, livestock troughs, solar pumping system from boreholes with an associated diesel generator backup system will be presented, as well as, the establishment of a water service pricing system, and the training of the water management committee.
