Transitioning to a Сlimate-Resilient Society: Empirical Evidence on What Drives the Adoption of Green Computing Policies in Nigerian Organisations

Promoting all efforts that centres around environmental sustainability is a collective responsibility. This paper recognizes the axiom that embracing green computing principles across all sectors, not just in corporations, leads to low-carbon development strategies and contributes positively to our planet. Hinged on this perspective, this study was poised to succinctly identify what drives the adoption of green computing policies, justify them, and recommend strategic policies based on the existing experience of other developed countries. The present study employed convenience sampling, a widely used non-probability sampling method, where participants are selected based on their availability and willingness to participate in the study. Limitations that hinder the adoption of green computing policies in some Nigerian organizations were examined. Primary data was collected from 52 participants, specifically top managers on the awareness, adoption, or practice of green computing policies in their affiliated organizations. Most respondents claimed awareness of green computing policies, while the use of power management features was considered the most adopted green initiative. However, when respondents were asked whether their organizations were doing enough to reduce their carbon footprint and operational cost through green computing initiatives, most respondents (61.5%) claimed their organization was not doing enough in this regard. It is important to note that this study considered several factors that are critical for the adoption of green computing, namely knowledge transfer, financing, availability of basic infrastructure (energy supply), presence of investors and the increasing number of recycling centres. Additionally, this paper reasoned that achieving a climate-resilient society, particularly through the adoption of green computing principles, necessitates ongoing and deliberate efforts focused on public awareness, green investment, and stringent corporate green policy guidelines, with a focused training approach for every member of the organization.

Multi – Robot Exploration Supported by Enhanced Localization with Reduction of Localization Error Using Particle Swarm Optimization

Exploration of an area by a group of robots is an active research field of robotics as multi-robot exploration is applied extensively in several real life scenarios. The major challenges in such exploration are the availability of communication infrastructure as communication plays a key role in the coordination of team of robots for effective coverage of the area under exploration. But in disaster affected scenarios, there will be no existing communication infrastructure available and this makes the exploration ineffective and time consuming. Another challenge is in the localization process each robot is carrying out to update the map as well as for exchange of information with other robots. In this paper, an enhanced Multi-robot exploration strategy is introduced. The base of the exploration strategy is two techniques. The first one being localization of each robot involved in the exploration and this is done with the help of trilateration where three anchors are required which will be setup before the exploration starts. The second part is navigation and avoiding overlapping or missing out sectors while exploring. This is done with help of a navigation policy called frontier cell based approach. Further to this, the exploration strategy is supported with localization error reduction scheme in which the localization error is reduced with the help of Particle Swarm Optimization (PSO). The entire scheme is simulated and exploration time is analyzed for the same environment in different obstacle density and different number of robots to perform exploration. The results show the scheme is better than many existing multi-robot exploration strategies. Precisely, the proposed scheme is able to reduce the localization error to a threshold level of 0.02cm or below which can be considered as novel contribution towards the exploration strategies.

Assessment of Immunization Coverage and its Determinants Amongst Children in an Urban Area. Study Protocol of a Cross Sectional Study

Abstract* Introduction The country’s immunization rate is frequently below the international and national goals, and it is not distributed evenly. Children should be immunized for several reasons, chief among them being that it is the main defense against a variety of serious and frequently life-threatening illnesses. Every year, it prevents debilitating illness and disability and saves millions of lives throughout the world. The urban population in India is experiencing exponential growth. However, the public sector’s urban healthcare delivery system has encountered difficulties in keeping up with the rapid pace, exhibiting limitations in its reach and falling short of meeting the increasing demands. There is a need for government to pay attention at immunization rates and related variables in children (12–23 months) in the urban area. Objectives • To assess the overall immunization coverage rate for children in the urban area. • To assess the determinants associated with immunisation coverage in an urban area. • To explore healthcare access and infrastructure: Examine the availability and accessibility of healthcare facilities and vaccination services within the urban area. Method Information will be collected using semi- structured questionnaire in kobo collect tool. The parents of the child will be asked whether they have their immunization cards with complete immunization of their children. Study implications This study seeks to appraise the participant’s current immunization status with association to various determinants related to immunisation coverage. The study will also explore the availability of health infrastructure in association with immunization coverage. Furthermore, the gathered data may be utilized in further studies.

Port Access Fluidity Management during a Major Extension Project: A Simulation-Based Case Study

The increasing demand for freight services and the use of larger vessels to meet this demand has led to challenges related to storage space and logistics activities, highlighting the need for improvements in port infrastructure for better logistics management. At a crucial phase in its growth, the Port of Trois-Rivières in Canada is planning a major expansion, including the construction of a new terminal to enhance its hosting capacities and freight services. This expansion faces potential access congestion problems during the planned construction, exacerbated by the port’s urban setting. In response to the needs identified by the port authorities for this event, the study’s objective is to assess the implications of increased construction and freight truck flows on access gate fluidity and the impact of additional access infrastructure investment to mitigate potential congestion. These evaluations aim to define effective access management strategies throughout the construction period of the new terminal. To address these complexities, our approach is based on scenario analysis in variants co-constructed with the partner. These scenarios are evaluated using simulation models, configured according to parameters calibrated with a granularity that allows congestion detection. The results enabled an evaluation of the capability of existing and potential gates to manage access. Subsequently, recommendations were shaped in accordance with the expected objectives to manage access traffic effectively. These recommendations concern the optimization of construction activity planning, the layout and planning of access, and the importance of enhanced collaboration between municipal and port authorities for more controlled road traffic management. Recognizing the importance of synchromodality, road network centrality management, and the outsourcing of capacity through inter-port cooperation and with dry ports to manage congestion, these tools will be discussed in this work. The study proposes an approach that reconciles scientific rigor with the implementation constraints of the proposed solutions, allowing this study wider applicability in various port contexts facing challenges in this field of study.

Use of the 23S rRNA gene as a target template in the universal loop-mediated isothermal amplification (LAMP) of genomic DNA from phytoplasmas.

Plant-pathogenic bacteria cause numerous diseases in host plants and can result in serious damage. Timely and accurate diagnostic techniques are, therefore, crucial. While advances in molecular techniques have led to diagnostic systems able to distinguish known plant pathogens at the species or strain level, systems covering larger categories are mostly lacking. In this study, a specific and universal LAMP-based diagnostic system was developed for phytoplasmas, a large group of insect-borne plant-pathogenic bacteria that cause significant agricultural losses worldwide. Targeting the 23S rRNA gene of phytoplasma, the newly designed primer set CaPU23S-4 detected 31 'Candidatus Phytoplasma' tested within 30 min. This primer set also showed high specificity, without false-positive results for other bacteria (including close relatives of phytoplasmas) or healthy plants. The detection sensitivity was ~10,000 times higher than that of PCR methods for phytoplasma detection. A simple, rapid method of DNA extraction, by boiling phytoplasma-infected tissues, was developed as well. When used together with the universal LAMP assay, it enabled the prompt and accurate detection of phytoplasmas from plants and insects. The results demonstrate the potential of the 23S rRNA gene as a versatile target for the LAMP-based universal detection of bacteria at the genus level and provide a novel avenue for exploring this gene as molecular marker for phytoplasma presence detection.IMPORTANCEPhytoplasmas are associated with economically important diseases in crops worldwide, including lethal yellowing of coconut palm, "flavescence dorée" and "bois noir" of grapevine, X-disease in stone fruits, and white leaf and grassy shoot in sugarcane. Numerous LAMP-based diagnostic assays, mostly targeting the 16S rRNA gene, have been reported for phytoplasmas. However, these assays can only detect a limited number of 'Candidatus Phytoplasma' species, whereas the genus includes at least 50 of these species. In this study, a universal, specific, and rapid diagnostic system was developed that can detect all provisionally classified phytoplasmas within 1 h by combining the LAMP technique targeting the 23S rRNA gene with a simple method for DNA extraction. This diagnostic system will facilitate the on-site detection of phytoplasmas and may aid in the discovery of new phytoplasma-associated diseases and putative insect vectors, irrespective of the availability of infrastructure and experimental resources.

Exploring transportation equity issues for persons with disabilities: The impact of gender on mobility and accessibility indicators

IntroductionPersons with disabilities still face numerous barriers in their everyday lives, especially in transportation. The problem of access to transportation is identified through fewer daily trips and more barriers in public transport. These problems indicate transportation equity issues among persons with disabilities. Another issue recognized in previous studies was a gender imbalance in the samples that could indicate gender equality problems among persons with disabilities. This paper aims to investigate mobility and accessibility indicators among persons with disabilities, with a particular emphasis on the impact of gender, in order to explore two critical transportation equity issues: inclusivity and social justice. MethodsThe mobility and accessibility indicators analyzed in this research were the Number of daily trips, Mobility satisfaction, Infrastructure accessibility satisfaction, and Modal distributions of daily trips. The data about indicators was collected by an online version of a questionnaire. The research was performed on 100 persons with disabilities from Serbia, equally distributed by gender. The most common recorded diagnosis of the respondents was spinal cord injury. ResultsIn general, respondents made 3.26 trips per day. At two transportation modes, we identified significant differences between males and females. Males frequently tripped as passenger car drivers, and females often traveled as passengers in passenger cars. Additionally, nine Bayesian linear regression models with weak informative prior distributions brought much helpful information. ConclusionsThe obtained results bring stakeholders valuable information in creating policies, practices, and recommendations to achieve specific goals related to transportation equity. Improving flexibility and time efficiency of females’ trips and resolving the problem of females’ fear of abuse and harassment in taxi cars were recognized as the two most critical topics.
