    The purpose of this study is to examine primary school children’s response on the use of audio-visual learning processes - A case study of Chokhmah International Academy, Port-Harcourt (owned by Salvation Ministries). It looked at the elements that enhance pupils’ response to educational television programmes and their hindrances to these programmes, and how audio-visual has affected the learning process. This work will be useful to Designers and presenters of educational television programmes as well as educationalists. Five research questions and one null hypothesis were posed to guide the study to a logical conclusion. A structured questionnaire was designed and administered to a randomly selected one hundred and six (106) pupils. Data generated from the research questions were analyzed using descriptive statistics while the null hypothesis was analyzed using the Pearson Product Moment Correlation Statistics. The findings of this study reaffirmed a high response of primary school pupils to audio-visual learning process and that the use of audio-visual learning process boosts the pupils’ social and intellectual ability to develop. Based on the findings of this study, it was recommended that the age range of students should be put into consideration; and that well-produced and sponsored educational programmes by government and private organizations should be encouraged

    This study is on the influence of mass communication on social change: a study of press reports on child labour and women trafficking. The study is aimed at addressing the problem of child labour and women trafficking in Rivers State. A total of 16 press reports were collected through purposive sampling from Rivers State University of Science and Technology Library and Newspaper morgues. These press reports on child labour and women trafficking were studied for 10 months at an interval of 2 months from September 2003 – June 2004. The press reports collected was content analyzed to determine their nature of report. All the press reports analyzed were favourable, they were in support of the fight against child labour and women trafficking; that government agencies, non-governmental organizations and the media have a role to play in putting an end to child labour and women trafficking; that child labour and women trafficking persist because parents and children are not adequately educated on the dangers of child labour and women trafficking;. From the summary of the finding, it was discovered that, some parents see their children as source of income because of poverty and ignorance, that majority of victims of child labour and women trafficking are born to parents of lower class. The researcher then recommends that the government agencies, non-governmental organizations and the media should join forces to educate the masses on the dangers of engaging in child labour and women trafficking and the suffering of trafficked children

    Are you sitting uncomfortably?:A tale of comfort, energy and productivity

    Get PDF
    Maintaining a consistent indoor temperature causes one of the largest energy demands in UK. UK buildings are famously poorly insulated and expensive to heat and cool. This is set to become ever more challenging in a warming and rapidly changing climate. What if we allowed ourselves to be more uncomfortable and took more charge of our thermal comfort? Wouldn’t we then be healthier, more thermally delighted, more productive? Would we not also save energy and related carbon emissions? We offer this provocation, and set the challenge to identify how this should change the role of future ubiquitous environments

    Bearing an open “Pandora's Box”:HCI for reconciling everyday food and sustainability

    Get PDF
    The sustainability of food is a significant global concern with a drastic change required to mitigate complex social, environmental, and economic issues like climate change and food security for an ever increasing population. In this article, we set out to understand the place of food in people's lives, their mundane yet surprisingly complex ways of sourcing their food, and the processes of transition, past and ongoing, that shape these choices. Our goal is to understand the potential role for digital interactions in supporting the various ways that food consumption can be made more sustainable. To inform this exercise, we specifically set out to contrast the journeys of committed sustainable “food pioneers” with more conventional mainstream consumers recruited in branches of a UK supermarket. This contrast highlights for both groups the various values, and “meaningfulness” attached to foods and meals in people's lives, and suggests ways in which food choice and pro-sustainable practices can be supported at least in part by new digital technologies

    Demand around the clock: Time use and data demand of mobile devices in everyday life

    Motivated by mobile devices’ growing demand for connectivity, and concern in HCI with the energy intensity and sustainability of networked services, in this paper we reveal the impact of applications on smartphones and tablets in terms of network demand and time use. Using a detailed mixed methods study with eight participants, we first provide an account of how data demand has meaning and utility in our participants’ social practices, and the timing and relative impacts of these. We then assess the scale of this demand by drawing comparison between our fine-grained observations and a more representative dataset of 398 devices from the Device Analyzer corpus. Our results highlight the significant categories of data demanding practice, and the identification of where changes in app time and duration of use might reduce or shift demand to reduce services’ impacts

    Towards an holistic view of the energy and environmental impacts of domestic media and IT

    Get PDF
    To date, research in sustainable HCI has dealt with eco-feedback, usage and recycling of appliances within the home, and longevity of portable electronics such as mobile phones. However, there seems to be less awareness of the energy and greenhouse emissions impacts of domestic consumer electronics and information technology. Such awareness is needed to inform HCI sustainability researchers on how best to prioritise efforts around digital media and IT. Grounded in inventories, interview and plug energy data from 33 undergraduate student participants, our findings provide the context for assessing approaches to reducing the energy and carbon emissions of media and IT in the home. In the paper, we use the findings to discuss and inform more fruitful directions that sustainable HCI research might take, and we quantify how various strategies might have modified the energy and emissions impacts for our participants

    Data-driven curation, learning and analysis for inferring evolving IoT botnets in the wild

    The insecurity of the Internet-of-Things (IoT) paradigm continues to wreak havoc in consumer and critical infrastructure realms. Several challenges impede addressing IoT security at large, including, the lack of IoT-centric data that can be collected, analyzed and correlated, due to the highly heterogeneous nature of such devices and their widespread deployments in Internet-wide environments. To this end, this paper explores macroscopic, passive empirical data to shed light on this evolving threat phenomena. This not only aims at classifying and inferring Internet-scale compromised IoT devices by solely observing such one-way network traffic, but also endeavors to uncover, track and report on orchestrated "in the wild" IoT botnets. Initially, to prepare the effective utilization of such data, a novel probabilistic model is designed and developed to cleanse such traffic from noise samples (i.e., misconfiguration traffic). Subsequently, several shallow and deep learning models are evaluated to ultimately design and develop a multi-window convolution neural network trained on active and passive measurements to accurately identify compromised IoT devices. Consequently, to infer orchestrated and unsolicited activities that have been generated by well-coordinated IoT botnets, hierarchical agglomerative clustering is deployed by scrutinizing a set of innovative and efficient network feature sets. By analyzing 3.6 TB of recent darknet traffic, the proposed approach uncovers a momentous 440,000 compromised IoT devices and generates evidence-based artifacts related to 350 IoT botnets. While some of these detected botnets refer to previously documented campaigns such as the Hide and Seek, Hajime and Fbot, other events illustrate evolving threats such as those with cryptojacking capabilities and those that are targeting industrial control system communication and control services

    Impression Management and Employee Contextual Performance in Service Organizations (Enterprises)

    Get PDF
    This study aims to investigate the effect of impression management on employee contextual performance in service organizations using quantitative methods. The social influence theory, which explains the role of superior influence over the subordinate, served as the theoretical underpinning for the study. A cross-sectional survey design was adopted in line with positivism research philosophy. The accessible population of this study consists of one hundred selected service-oriented firms (four-star hotels, fast food restaurants, and travel agencies) operating in the southern part of Nigeria. The sample consists of middle managers, human resource managers, front desk officers, housekeepers, and customer relationship managers. Frequency distribution was used to analyze participants’ profiles, while linear regression was employed to analyze the formulated hypotheses. Statistical Package for the Social Sciences (SPSS) 20.0 served as statistical software. Linear regression results suggest that self-promotion exerted a significant positive effect on co-worker support. Ingratiation demonstrated a significant positive effect on customer satisfaction. It appears that exemplification exerted a significant positive effect on enterprise compliance. The outcome of this study has demonstrated that traditional managerial skills can no longer hold water in contemporary service-oriented organizations because of the workplace's dynamic and changing technological structure. This study concludes that impression management can assist managers in influencing their employees positively to achieve organizational objectives. Doi: 10.28991/ESJ-2023-07-02-05 Full Text: PD
