Artificial evil and the foundation of computer ethics

Moral reasoning traditionally distinguishes two types of evil:moral (ME) and natural (NE). The standard view is that ME is theproduct of human agency and so includes phenomena such as war,torture and psychological cruelty; that NE is the product ofnonhuman agency, and so includes natural disasters such asearthquakes, floods, disease and famine; and finally, that morecomplex cases are appropriately analysed as a combination of MEand NE. Recently, as a result of developments in autonomousagents in cyberspace, a new class of interesting and importantexamples of hybrid evil has come to light. In this paper, it iscalled artificial evil (AE) and a case is made for considering itto complement ME and NE to produce a more adequate taxonomy. Byisolating the features that have led to the appearance of AE,cyberspace is characterised as a self-contained environment thatforms the essential component in any foundation of the emergingfield of Computer Ethics (CE). It is argued that this goes someway towards providing a methodological explanation of whycyberspace is central to so many of CE's concerns; and it isshown how notions of good and evil can be formulated incyberspace. Of considerable interest is how the propensity for anagent's action to be morally good or evil can be determined evenin the absence of biologically sentient participants and thusallows artificial agents not only to perpetrate evil (and forthat matter good) but conversely to `receive' or `suffer from'it. The thesis defended is that the notion of entropy structure,which encapsulates human value judgement concerning cyberspace ina formal mathematical definition, is sufficient to achieve thispurpose and, moreover, that the concept of AE can be determinedformally, by mathematical methods. A consequence of this approachis that the debate on whether CE should be considered unique, andhence developed as a Macroethics, may be viewed, constructively,in an alternative manner. The case is made that whilst CE issuesare not uncontroversially unique, they are sufficiently novel torender inadequate the approach of standard Macroethics such asUtilitarianism and Deontologism and hence to prompt the searchfor a robust ethical theory that can deal with them successfully.The name Information Ethics (IE) is proposed for that theory. Itis argued that the uniqueness of IE is justified by its beingnon-biologically biased and patient-oriented: IE is anEnvironmental Macroethics based on the concept of data entityrather than life. It follows that the novelty of CE issues suchas AE can be appreciated properly because IE provides a newperspective (though not vice versa). In light of the discussionprovided in this paper, it is concluded that Computer Ethics isworthy of independent study because it requires its ownapplication-specific knowledge and is capable of supporting amethodological foundation, Information Ethics.     

Attributions and Attitudes of Mothers and Fathers in Sweden

OBJECTIVE: The present study examined mean level similarities and differences as well as correlations between mothers' and fathers' attributions regarding successes and failures in caregiving situations and progressive versus authoritarian attitudes. DESIGN: Interviews were conducted with both mothers and fathers in 77 Swedish families. RESULTS: Fathers reported higher adult-controlled failure and child-controlled failure attributions than did mothers; these differences remained significant after controlling for parents' age, education, and possible social desirability bias. Significant positive correlations were found for mothers' and fathers' progressive attitudes, authoritarian attitudes, and modernity of attitudes after controlling for parents' age, education, and possible social desirability bias. CONCLUSIONS: We conclude that in Sweden fathers are more likely to attribute failures in caregiving situations both to themselves and to children than are mothers and that there is moderate concordance between fathers and mothers within the same family in progressive and authoritarian parenting attitudes.     

��I WAS TOLD IT WAS GOING TO BE HARD WORK BUT I WASN��T TOLD IT WAS GOING TO BE THIS MUCH WORK��: THE EXPERIENCES AND ASPIRATIONS OF UNDERGRADUATE SCIENCE STUDENTS

The recruitment and training of scientists is an area of international concern. Much of the research and policy focus around this issue in the UK has been on how science is taught in schools and in particular on the structure of the school science curriculum. Much less attention has been devoted to the undergraduate student experience and the trajectory that learners take which can lead to higher education and into careers as professional scientists and technicians. This paper reports the findings from a comparative study of the experiences and aspirations of almost 1,000 art and science undergraduates studying at 6 elite British universities. There is no evidence to suggest that undergraduate scientists are put off a career in the science, technology, engineering and mathematics field, although theirs is arguably a less positive experience than that of their peers who study arts subjects. Most science undergraduates have clear career aspirations which are largely linked to remaining in the field and often involve further study. For many, these aspirations lead them towards the applied sciences and away from a career in ‘pure’ research or academia.     

Brand’s Social Media Presence as Networks: The Role of Interactivity and Network Centrality on Engagement

Despite ample research on brand engagement via social media, little research considers the aggregate effect of multiple same-brand accounts on engagement. Multiple same-brand accounts are common because they allow brands to extend their reach, tailor their messaging, and cross-promote their products/services. Therefore, this study tests whether interaction between same-brand social media accounts and centrality within same-brand conversational networks is related to user engagement. An analysis of 3,380 brand accounts found that after controlling for interactions with users, interactions between brand accounts contributed significantly to user engagement and that account centrality measures were associated with measures of engagement.     

Reducing physical restraint in educational settings: a systematic literature review

Physical restraint is a restrictive practice used in schools across the UK and there have been recent concerns around the appropriateness and frequency of using this intervention with pupils. Current data suggest that pupils with Special Educational Needs (SEN), a vulnerable and diverse group, are experiencing the majority of physical restraint used in educational settings. Physical restraint can lead to negative emotional and physical consequences in pupils who experience it and it is, therefore, important to explore alternative strategies to reduce or eliminate its use in educational settings. A systematic literature search found 15 studies (date range 1999–2019) that explored the effectiveness of school-wide or individual approaches in reducing the frequency and/or duration of physical restraint. Most studies saw a significant decrease in physical restraint, and this study will discuss the key elements of the successful approaches, as well as consider the facilitators and barriers to implementation.     

Child care and family processes: Bi-directional relations between child care quality,home environments,and maternal depression

The current study examined whether within-family changes in child care quality and quantity predicted subsequent changes in home environment quality and maternal depression across early childhood (6 to 54 months of age). Data were drawn from the NICHD Study of Early Child Care and Youth Development (n = 1239; 77% White; 48% female; data collection from 1991 to 1996), and were analyzed using Random Intercept Cross-Lagged Panel Models. Within-family increases in child care quality predicted modest increases in home environment quality (β = .13–.17). These effects were most robust from child age 6 to 15 months. Increases in child care quality produced small, statistically non-significant, reductions in depression. Time-specific increases in child care quantity were not consistently predictive of either outcome.     

Students reflecting on test performance and feedback: an on-line approach

Undergraduate students accessing on-line tests in Human Biology in three Western Australian universities were asked to complete an on-line post-test reflective survey about their perceptions of their test performance in light of automated feedback. The survey allowed pre-determined choices and comment text boxes relating to students’ perceptions of their performance, self-identified areas of difficulty and suggested strategies for improving test performance. One-third of students undertaking on-line tests responded to the optional survey, and 60% of respondents thought reflecting on feedback was useful. Students reflecting on formative rather than summative assessment reported a more strategic approach to testing, often using it to assess their knowledge and prepare for future assessment. Their reflections were more internally focused on motivation and preparation compared with those assessed summatively. Respondents were more likely to be female, older, more experienced learners who had scored well in the test. Younger respondents expected higher scores than they achieved and were less likely to reflect, but, when they did, were more likely to select pre-determined reasons for their performance and less likely to suggest strategies for improvement. These results support formal training and scaffolded integration of reflection into on-line assessment feedback, especially for less experienced learners.     

Diving

The purpose of this study was to compare the reverse two and one half somersault dive in a tuck position (305C) performed by females (n = 24), and the reverse two and one half somersault dive in a pike position (305B) performed by males (n = 21), to determine changes required by females to successfully perform 305B. Key performance variables in reverse dives were also compared to those of forward dives. Video data of the dives performed at the 1999 FINA World Diving Cup were captured and digitised to obtain times and postures of the divers at specific events including hurdle landing, takeoff, and entry. Estimates of hurdle flight height and mass‐normalised work done on the springboard were obtained from hurdle and flight times. The males did more work on the springboard to achieve greater height and rotation than females. Females performing 305C had less hip and knee flexion at hurdle landing than males performing 305B and took longer to achieve maximum hip flexion after takeoff from the springboard. To progress from 305C to 305B females need to adjust their techniques to put more energy into the system. Desirable changes include increased height in the hurdle and increased hip and knee flexion prior to hurdle landing. Comparison of results for reverse dives with data previously presented for forward dives indicated that divers are more limited in the number of somersaults and dive position in reverse dives than forward dives despite equivalent or better height in reverse dives than forward dives.     

Opportunities and challenges facing NGOs using sport as a vehicle for development in post-apartheid South Africa

Post-apartheid South Africa manifests poor social indicators with over half the population living below the poverty line and the worst levels of inequality in the world, with much work needed to overcome the skewed legacy of apartheid. Sport suffered in this system resulting in unequal access to sporting facilities and opportunities, meaning many South Africans cannot exercise their right to play. Despite this legacy, sport can fulfil a vital developmental role in alleviating some of these issues. The state has a major role to play but it must be supported by civil society and non-governmental organisations (NGOs) who have the ability to deliver in situations where government has struggled. This article researches the opportunities and challenges NGOs encounter when using sport for development within the education system, in post-apartheid South Africa. This study used a qualitative approach to collect data on the opportunities and challenges encountered by two NGOs based in Cape Town that use sport as a means of development, but in markedly different ways. The study suggests that NGOs face a variety of conceptual, technical, logistical and organisational challenges using sport in schools and should enact certain measures to reduce resistance from educators and ensure successful programmes. The interaction between NGOs, schools and the state Department of Education is a complicated process that presents obstacles and opportunities. Nevertheless, despite these challenges it is clear NGOs can support schools in South Africa to optimise their physical activity programmes in the backdrop of a stagnating education system and a lack of sporting support from the government. NGOs in an educational setting such as schools operate in what Houlihan has identified as a crowded policy space. Yet, the observations in this study suggest that, particularly in the context of education, a partnership policy model of NGO work is preferred.     

Diving

The purpose of this study was to compare the backward two and one half somersault dive in a tuck position (205C) performed by females (n = 22) and the backward two and one half somersault dive in a pike position (205B) performed by males (n = 27) and by females (n = 6) to determine changes required by females to successfully perform 205B. Video data of the dives performed at the 1999 FINA World Diving Cup were captured and digitised to obtain times and postures of the divers at specific events including maximum depression, takeoff, and entry. Estimates of mass‐normalised work done on the springboard were obtained from flight times. Males performed 31% more mass‐normalised work on the springboard to gain height than females. Based on the dive scores and the short time to extend and prepare for entry it was concluded that females are not yet able to perform 205B with the same quality as they perform 205C. Females performing backward dives need to adjust their techniques to allow increased work on the springboard to generate height and rotation. Also, faster contraction of the hip flexors may allow them to achieve the tightest position more quickly to complete rotations with more time to prepare for entry.
