Influence of income on tertiary students acquisition of cellular productsDrotsky, GAP, Janse van Rensburg, B, de Jager, JW 18 October 2007 (has links)
Purpose: The purpose of the article is to determine whether there are any differences between high and low-income group
students in their selection of a cellular phone brand or network operator.
Design / Methodology / Approach: Four hypotheses are set to determine if there are any significant differences between
the two income groups in current decision-making. It is established that there exist no significant difference between high
and low-income students in their selection of cellular phones and network operators. The levels of agreement or
disagreement on various statements do, however, give an indication of the importance that students place on aspects that
they view as important when acquiring a cellular phone or network operator.
Findings: In the article, it is established that no significant differences exist between the two income groups. The levels of
agreement or disagreement indicate the importance that subscription method, social value, service quality and branding has
on student decision-making.
Implications: The article provides a better understanding of the influence that income plays in student’s decision-making in
acquiring cellular products and services. Possible future research in student cellular usage can be guided through the
information obtained in this article.
Originality / Value: The article provides information to cellular network operators, service providers and cellular phone
manufactures regarding the influence of income on students’ acquisition of cellular products and services. Information from
the article can assist in the establishment of marketing plans for the student market by these role players.

The impact of an auditory task on visual processing:implications for cellular phone usage while drivingCross, Ginger Wigington 03 May 2008 (has links)
Previous research suggests that cellular phone conversations or similar auditory/conversational tasks lead to degradations in visual processing. Three contemporary theories make different claims about the nature of the degradation that occurs when we talk on a cellular phone. We are either: (a) disproportionately more likely to miss objects located in the most peripheral areas of the visual environment due to a reduction in the size of the attentional window or functional field of view (Atchley & Dressel, 2004); (b) more likely to miss objects from all areas of the visual environment (even at the center of fixation) because attention is withdrawn from the roadway, leading to inattention blindness or general interference (Strayer & Drews, 2006; Crundall, Underwood, & Chapman, 1999; 2002), or (c) more likely to miss objects that are located on the side of the visual environment contralateral to the cellular phone message due to crossmodal links in spatial attention (Driver & Spence, 2004). These three theories were compared by asking participants to complete central and peripheral visual tasks (i.e., a measure of the functional field of view) in isolation and in combination with an auditory task. During the combined visual/auditory task, peripheral visual targets could appear on the same side as auditory targets or on the opposite side. When the congruency between auditory and visual target locations was not considered (as is typical in previous research), the results were consistent with the general interference/inattention blindness theory, but not the reduced functional field of view theory. Yet, when congruency effects were considered, the results support the theory that crossmodal links affect the spatial allocation of attention: Participants were better at detecting and localizing visual peripheral targets and at generating words for the auditory task if attention was directed to the same location in both modalities.

Positively Perceived Impacts of Cellular Phones on Nigerian SocietyNwosu, Azuakolam 01 August 2014 (has links)
This study examined the positive perceived impacts of cellular phones in the Nigerian society.The purpose of the study was to analyze the impacts of this technology in Nigerian society These impacts analyses were on the perceived changes in safety and well-being amongst users, satisfactions amongst users, and perceived connectivity amongst users of this technology. The researcher used employed facilitators to distribute survey in several cities in Nigeria. One Hundred and twenty-four people participated in survey questionnaires using five scale points. Results were summarized using descriptive statistics at 95% confidence interval level. From the results, the hypothese were retained that underserved customers outnumbered overserved customers in the Nigerians cellular phone usage, cellular phone usage has had some impact on the perceived safety and wellbeing of its users. In addition, the hypothesis also showed cellular phone usage has increased the perceived connectivity between the user and family.

Previous issue date: 2005 / Resumo: Este trabalho apresenta subsídios para uma análise preliminar dos efeitos da interação de campos eletromagnéticos com alguns tipos de tecidos, biológicos. A motivação está na necessidade da avaliação de tais efeitos tendo em vista a da grande difusão na utilização de aparelhos celulares. Nese sentido, os campos analisados estão nas freqüências de 800- 900 e 1800 MHz e nas potências de 600. 250 e 125 mW, respectivamente, que representam valores efetivamente utilizados, principalmente pela tecnologia digitai GSM (Global System for Mobile Communication). O método utilizado roi o FDTD. (Finite-Difference Time-Domain) implementado no software Matlab e os resultados de SAR (Specific Absorption Rate) foram obtidos e comparados com os dado:-publicados por algumas agendas reguladoras / Abstract: This work presents the basis for a primary analysis concerning the effects of iteraiton between electromagnetic fields and some kinds of biological tissues. The motivation is the evaluation need of such effects observing the great diffusion of mobile phones. Therefore, the analyzed fields are in the frequencies of 800. 900 and 1800 MHz with output power of 600, 250 and 125 mW. respectively, which correspond to effective!1, used values, most!) for GSM (Global System for Mobile Communication) digital technology. The used method was FDTD (Finite-Difference Time-Domain) and it was implememed using Mat lab software. The results related lo SAR (Specific Absorption Rate; were achieved and compared with the data published by some regulatory agencies / Mestrado / Eletrônica, Microeletrônica e Optoeletrônica / Mestre em Engenharia Elétrica
