A challenge to the extended mind hypothesis
The extended mind hypothesis (EMH) has been a major focus of debate since its publication in 1998, prompting interest from proponents and exponents alike. At the heart of the paper is the aim of understanding mental phenomena, specifically, what constitutes a mental state. To fully understand EMH it is crucial to appreciate the distinction between our mental states. Firstly, we have mental states that derive from our experiences, these are considered conscious states. They contain feelings or emotions, for example, falling in love, having a pain or being moved by a piece of music. This type of mental state has the feature of phenomenology, a particular character or quality, for example, there is something it is like to see a red apple. Secondly, there are non-conscious mental states that occur without our knowledge of them or indeed we perform actions without consciously thinking about it. These types of mental states possess intentionality meaning that they are about something, for example, I believe that Oswald shot Kennedy or that I am scared of the dark. It is with this clear distinction between conscious and unconscious mental states defined that we can begin to understand the argument presented by Clark and Chalmers
New Technology in Education as Viewed through the Utopic and Dystopic Worlds of Science Fiction
The use of educational technology has become a focus of reform efforts designed to enrich student learning. Proponents of technology view it as the panacea of education while others ask us to question this myth-information. Throughout America, school districts are designating millions of dollars for technology. Nevertheless, while there are schools with desirable infrastructures, too many schools are ill equipped for enhancing learning through technology. In addition, many classrooms house computers used to merely advance traditional teaching modes, e.g., drill and practice, rather than teach the importance of social responsibility for humankind and the environment through our use of technology. This study is designed to analyze the reasons for the continued existence of challenges to the integration of educational technologies through the lens of science fiction literature and film. Metaphorically, participants link science fiction plots and characters to their orientations to technology, to present experiences with technology in the field of education, to their future expectations of technological advancements, and to the need to reconceptualize our understanding of technology as a mere tool. It is this association with the worlds of science fiction that provides educators and policy makers with an understanding of ourselves in relation to others and technology. Research into teachers\u27 attitude towards technology integration can provide relevant information regarding solutions to the persistent challenges facing the adoption of technology in education. Participants\u27 personal stories and their metaphorical analysis of science fiction indicate that educators\u27 orientation to technology, self-efficacy, perceptions of technology, technology resources, and training and support are predictors of technology integration. In addition, educators\u27 involvement in the planning stages of technology programs and their accountability for high-stakes testing are also significant factors. Conclusions derived from the findings suggest that those involved in technology reform efforts in education need to address educators\u27 concerns for inclusion in the design, development, and implementation of plans for the integration of technology in classroom instruction
Non-technical skill gaps in Australian business graduates
Purpose – The need for “job-ready” graduates has catalysed the development of non-technical skills in higher education institutions worldwide. Continued criticism of business school outcomes has provoked this examination of non-technical skill deficiencies in Australian business graduates. The purpose of this paper is to compare findings with existing literature on skill gaps in other developed, culturally-similar economies, underscore the generality of identified problems, and highlight to stakeholders in undergraduate education those areas requiring curricula review. Design/methodology/approach – In total, 211 managers/supervisors of business graduates and 156 business academics assessed the typical performance levels of Australian business graduates against a comprehensive framework of 20 skills and 45 associated workplace behaviours. Ratings were examined within and across the two samples and variations analysed by work area, business activity and business discipline. Findings – Some differences were detected between academic and employer skill ratings of certain workplace behaviours. Respondents agreed that although graduates are confident and proficient in certain non-technical skills, they are deficient in vital elements of the managerial skill set. There were differences in employer ratings across certain business activities and work areas but none detected in academic ratings from different business disciplines. Originality/value – Findings broadly align with literature from previous studies, highlighting the generality of presented skill deficiencies. The study suggests that although business schools are producing well-rounded graduates, they are overlooking the development of certain non-technical skills deemed essential in managers. This urges curricula reform and raises questions on who is responsible for developing work readiness in graduates. The implications of differing perceptions of graduate performance are discussed
Researching maternal, neonatal and child health service use in rural and pastoralist Ethiopia: A key informant research approach
Like many nations in sub-Saharan Africa, Ethiopia has both a high neonatal mortality rate and maternal mortality ratio and is unlikely to meet Millennium Development Goals 4 and 5 by 2015. This working paper examines how Key Informant Research (KIR) in rural and pastoralist Ethiopia will identify facilitators and barriers to the use of maternal, neonatal and child health services. The methodology is informed by Participative Ethnographic Evaluation Research (PEER) and Key Informant Monitoring (KIM). Key Informant Research (KIR) training will provide research skills to Health Extension Workers (HEWs) and Non-government organisation (NGO) staff to enable them to develop research questions, collect data and participate in preliminary data analysis. This will enable the identification of strategies that improve the identification of risk, enhance early referral, increase access, affordability and acceptability of skilled birthing services in rural and pastoralist Ethiopia
Radio Sources in the 2dF Galaxy Redshift Survey. I. Radio Source Populations
We present the first results from a study of the radio continuum properties
of galaxies in the 2dF Galaxy Redshift Survey, based on thirty 2dF fields
covering a total area of about 100 square degrees. About 1.5% of galaxies with
b(J) < 19.4 mag are detected as radio continuum sources in the NRAO VLA Sky
Survey (NVSS). Of these, roughly 40% are star-forming galaxies and 60% are
active galaxies (mostly low-power radio galaxies and a few Seyferts). The
combination of 2dFGRS and NVSS will eventually yield a homogeneous set of
around 4000 radio-galaxy spectra, which will be a powerful tool for studying
the distriibution and evolution of both AGN and starburst galaxies out to
redshift z=0.3.Comment: 14 pages, 7 figures, accepted for publication in PAS
Plasma Total Glutathione in Humans and its Association with Demographic and Health-Related Factors
The tripeptide glutathione is proposed to be protective against a number of chronic diseases including cardiovascular disease and cancer. However, there have been few studies of plasma glutathione levels in humans and in those studies the numbers of participants have been very small. In an exploratory analysis the determinants of plasma total glutathione (GSHt) were investigated in a group of 100 volunteers aged 18–61 years in Atlanta, Georgia, USA during June and July 1989. Data on demographic and health-related factors were collected by interview and plasma GSHt was measured using a recently modified laboratory method. The mean concentration of plasma GSHt for all 100 participants was 761 pg/1, with a standard deviation of 451 pg/1, a range of 86–2889 pg/1 and a median of 649 pg/1. Men had significantly higher levels of plasma GSHt than women (924 v. 692 pg/1; P = 0.006). Seventh-day Adventists participating in the present study had higher plasma GSHt levels than other subgroups defined by race and/or religion. Among Seventh-day Adventists consumption of a vegetarian diet was associated with increased plasma GSHt concentration (P = 0.002). Plasma GSHt levels also appeared to vary by race, but relationships with race could not be clearly disassociated from relationships with religion. Among white participants plasma GSHt concentration decreased with age in women but increased with age in men (P = 0.05). Few other factors were associated with plasma GSHt concentration, although use of oral contraceptives (P=0.10) was somewhat associated with decreased plasma GSHt levels. These findings suggest that plasma GSHt levels may vary with several demographic and health-related attributes and support the need for further research on this potentially important disease-preventive compound. © 1993, The Nutrition Society.
