The effect of attention on perceived brightness and contrast was investigated in eight experiments. Attention was manipulated by engaging observers in an attention-demanding concurrent task or by directing attention to a location with a peripheral cue. In all of the dual-task manipulations, attention reduced the variability of responses. However, attention did not affect the brightness of stimuli, nor did it affect the amount of simultaneous brightness contrast. Results with peripheral location cues were similar; however, the effect of attention in these (...) experiments could be attributed to nonperceptual factors. The metaphorical “spotlight” of attention reduces observers' uncertainty about the brightness of a stimulus, but it does not “illuminate” in terms of brightness or contrast. (shrink)

Professionalisation of Journalism has been a subject under global scrutiny since the nineteenth century. Contemporary studies show how journalism profession grapples with the implementation of standard journalism education and practices across the globe. The author discovered that the development of journalism has remarkable link with the advent of Christianity, however, an apparent decline of ethical values in higher education and professional practices abound thereby revealing the type of quality of education provided and the substandard nature of journalistic Professionalisation. Empirical research (...) conducted in this regard geared towards assessing the socio-ethical relevance of Professionalisation as beneficial to democratic development, and the challenges journalists encounter that hinder the implementation of professional ethics and cultural values as a contribution to human dignity, rights, justice, solidarity and the common good. To critically examine these phenomena, this research study is anchored of scientific materials. It adopted the see-judge-act (A Theological methodology approach used in appraising socio-ethical situations) as well as qualitative and quantitative methods. The researcher conducted thirteen semi-standardised interviews as well as analysed 200 data samples (twenty-three questions) with Mayring model and (SPSS) was used to evaluate the quantitative data. The research results showed the thirteen different interview partners unanimously consented that journalism in Nigeria must be professionalised and there is need to integrate Christian social ethics and culture driven values into the training curriculum if journalists are to regain their credibility and integrity. The tested hypotheses showed statistical significance (p. (shrink)

Preoperative informed consent is a legal and ethical requirement that ensures patients understand a procedure, its associated risks and benefits, alternative treatment options, and potential complications to make an informed decision about their care. This cross‐sectional study evaluated the informed consent process for major orthopaedic surgeries at a tertiary hospital in Nigeria. A self‐administered questionnaire was used to collect data from 120 adult participants. Results showed that many patients do not read the consent form before signing it, and surgeons do (...) not adequately explain the alternatives to surgery, potential risks, and available anaesthetic options. Higher‐educated patients are more likely to read the consent form. Surgeons performed well in explaining the nature of the condition and prognosis, the procedure's potential benefits, and answering patients' questions. The study emphasises the need to improve the informed consent process to ensure patients understand and can make rational decisions about their healthcare. (shrink)

We explore the Covid-19 pandemic’s impact on companies’ sustainability strategies and practices. Prior research has identified a number of factors that shape such effects, including crisis severity, resource slack, and prior investments, but their interactions have not been given much attention. We thus collected qualitative data on 25 companies in four African countries, which we analyzed inductively and iteratively through cross-case comparison and with fuzzy set Qualitative Comparative Analysis. We identify two pathways associated with strengthening responses (“building on strengths” and (...) “governance gap-filling”) and three associated with restricting responses (“hard hit,” “low-road business-as-usual,” and “bunkering down”). Our findings enhance our understanding of organizational responses to crises by attending to configurational effects, by elaborating the role of prior sustainability investments, and by foregrounding the relevance of governance contexts. We describe implications for future research and managers, investors, and sustainability initiatives such as the United Nations Global Compact. (shrink)
