EXCLUDED FROM EDUCATION AND WORK: PERCEPTIONS OF AT RISK YOUTH
âAt riskâ is a concept that reflects probability or likelihood, not certainty. Youth living in resource-poor rural areas and not in education, employment or training (NEET) have fewer opportunities to make the transition to the role requirements of adulthood â specifically to productive work. Risk factors such as exclusion from more than one key societal system, such as education and the economy, increase the chance of youth not being able to make a successful transition into adulthood. We argue that at risk youth and their environments should be specifically targeted for interventions by social service providers. The promotion of their inclusion in all spheres of community life â from work to active citizenship, building on the strengths and assets of young people, their families and the community â raises the chances of positive outcomes (Moore, 2006)
Observations of V838 Mon in the CO rotational lines
We investigate the structure of a field around the position of V838 Mon as
seen in the lowest CO rotational transitions. We also measure and analyse
emission in the same lines at the position of V838 Mon.Observations have
primarily been done in the CO J = 2-1 and J = 3-2 lines using the KOSMA
telescope. A field of 3.4 squared degrees has been mapped in the on-the-fly
mode in these transitions. Longer integration spectra in the on-off mode have
been obtained to study the emission at the position of V838 Mon. Selected
positions in the field have also been observed in the CO J = 1-0 transition
using the Delingha telescope.In the observed field we have identified many
molecular clouds. They can be divided into two groups from the point of view of
their observed radial velocities. One, having V(LSR) in the range 18-32 km/s,
can be identified with the Perseus Galactic arm. The other one, having V(LSR)
between 44-57 km/s, probably belongs to the Norma-Cygnus arm. The radial
velocity of V838 Mon is within the second range but the object does not seem to
be related to any of the observed clouds. We did not find any molecular buble
of a 1 degree dimension around the position of V838 Mon claimed in van Loon et
al. An emission has been detected at the position of the object in the CO J =
2-1 and J = 3-2 transitions. The emission is very narrow (FWHM ~ 1.2 km/s) and
at V(LSR) = 53.3 km/s. Our analysis of the data suggests that the emission is
probably extended.Comment: paper accepted in A&
A model of an expanding giant that swallowed planets for the eruption of V838 Monocerotis
In early 2002 V838 Monocerotis had an extraordinary outburst whose nature is
still unclear. The optical light curve showed at least three peaks and imaging
revealed a light echo around the object - evidence for a dust shell which was
emitted several thousand years ago and now reflecting light from the eruption.
Spectral analysis suggests that the object was relatively cold throughout the
event, which was characterized by an expansion to extremely large radii. We
show that the three peaks in the light curve have a similar shape and thus it
seems likely that a certain phenomenon was three times repeated. Our suggestion
that the outburst was caused by the expansion of a red giant, followed by the
successive swallowing of three relatively massive planets in close orbits,
supplies a simple explanation to all observed peculiarities of this intriguing
object.Comment: 5 pages, 1 LaTex file, 2 .eps figures, accepted for publication in

V4332 Sagittarii revisited
The eruption of V4332 Sgr discovered in February 1994 shows striking
similarities to that of V838 Mon started in January 2002. The nature of these
eruptions is, however, enigmatic and unclear. We present new photometric and
spectroscopic data on V4332 Sgr obtained in April-May 2003 at the SAAO. The
obtained spectrum shows an unusual emission-line component superimposed on an
early M-type stellar spectrum. The emission-line spectrum is of very low
excitation and is dominated by lines from neutral elemets (NaI, FeI, CaI) and
molecular bands (TiO, ScO, AlO). We also analyse all the observational data,
mainly photometric measurements, available for V4332 Sgr. This allows us to
follow the evolution of the effective temperature, radius and luminosity of the
object since February 1994 till 2003. We show that the observed decline of
V4332 Sgr can be accounted for by a gravitational contraction of an inflated
stellar envelope. The combined optical and infrared photometry in 2003 shows
that apart from the M-type stellar component there is a strong infrared excess
in the KLM bands. This excess was absent in the 2MASS measurements done in 1998
but was probably starting to appear in K in 1999 when the object was observed
in the DENIS survey. We interpret the results in terms of a stellar merger
scenario proposed by Soker & Tylenda. The infrared excess is likely to be due
to a disc-like structure which is either of protostellar nature or has been
produced during the 1994 eruption and stores angular momentum from the merger
event.Comment: 11 pages, 5 figures, accepted in Astronomy & Astrophysic
The effect of using a computer-based exploration tool on children's career development learning
Historically the process of career development was thought of as occurring in adolescence and adulthood; however, the renewed emphasis on lifelong career development has led to a greater focus on the career developmental stage of childhood. The present research focused on the development and trialling of a research-based computerised career exploration tool, Growing-up: Children Building Careers⢠(GCBCâ˘) that can be used for early intervention in childrenâs career development. The integration of developmental considerations within a career developmental context is of paramount importance, considering that child and career developmental theories share certain basic foundational principles such as the dual recognition of identifiable life stages and the resolution or accomplishment of associated tasks. The focus of the research is to provide access to a research-based tool that can assist learners with developing age appropriate career developmental skills. As the overview of education policy and existing programs will show, there are challenges in providing access to and improving the nature, level, and quality of career development services. Gaps in access to career development learning are particularly evident at the elementary education level. Furthermore it is clear that learners need to be at the centre of a radical rethink of careers services within a lifelong learning framework in order to ensure access to navigational tools throughout a lifetime of work and study transitions. Digital environments, such as the GCBCâ˘, are tools that broaden and extend learning possibilities for children and appropriately designed digital environments can provide a vehicle that can take children further than they might travel unassisted. The research is divided into five phases and includes eight to ten year old children as participants. Phase one focused on the program design and pilot study (ensuring content validity and age-appropriate language use), while phases two to five focused on the fieldwork (i.e., pre âtest, program exposure, post-test, and focus group discussions). The researcher made use of a mixed research design that combines both quantitative and qualitative research methods. The total sample consisted of 146 children between the ages of eight to ten years old. The control group had 72 children and the experimental group 74 children with a mean age of 8.74 years (SD = 0.63) for the total sample. The quantitative data collection entailed a pre-and post-test design with learnersâ career development measured with the Childhood Career Development Scale (CCDS) and their career awareness with the Revised Career Awareness Survey (RCAS). Qualitative data was collected in the form of two focus group discussions, which included a small sample of children from the experimental group, as well as insights gained from educators following the GCBC⢠fieldwork. The quantitative statistical analysis included descriptive and inferential statistics which allowed the researcher to not only describe the research findings, but to confirm the effectiveness of the GCBC⢠as an intentional career development learning program. Furthermore, the responses of the children and educators who participated in or witnessed the facilitation of the GCBC⢠provided support for the GCBC⢠as a meaningful career learning experience which can be successfully implemented in educational settings
A longitudinal study of the occupational aspirations and perceptions of nine to twelve year-old South African children
Despite the acknowledgement of the developmental nature of careers, little attention has been focused on identifying shaping influences during childhood. This noticeable deficiency in the literature marked the start of the current longitudinal study which was designed to provide information on the career development of nine to twelve-year old South African children. In South Africa research focusing on preadolescent career development is limited with existing research indicating the need to further explore how childrenâs career choice process initially develops. The study aimed to explore and describe the changes that occur, if any, over a four-year period in terms of occupational interest typology, occupational status levels, occupational gender stereotypes and occupational gender traditionality. Both developmental and career developmental theories were used to provide a context for exploring this process of preadolescent career development. It was decided that quantitative research methods would provide the necessary structure needed to conduct the research. Although semistructured interviews and biographical questionnaires were used to record the verbal data, the data obtained was transposed into nominal data for analysis. Participants responded to questions within a semi-structured interview that focused on four broad areas of questioning. These questions explored participantsâ occupational aspirations, how many occupations they knew about, how much they knew about the identified occupation, and the extent to which they held gender-role stereotypes about certain occupations. After the data was iv Key words: career development, children, longitudinal research, occupational aspirations captured it was coded according to Holland's (1985) classification system of occupational interest types. The occupational aspirations expressed by the participants were also coded in terms of their status levels. The coded data was then further analysed using descriptive statistics in the form of frequency counts and percentages. Results from the study support both child and career development theory which view childhood as a time of rapid growth with critical development in various competency areas (including occupational aspirations and perceptions). Although the current study found that most children aspired to Social occupations, the popularity of this typology decreased with increasing age as more children aspired to Investigative, Artistic, and to a lesser extent, Realistic typologies at age twelve. Furthermore, it appears that children, like adults, are aware of status differentials among occupations and that this awareness subsequently influences occupational aspirations. Lastly, the findings broadly provide support for both national and international research in that it was established that an increase in age reflects a decrease in gender-stereotypical perceptions of occupations. The present study gained valuable insight into how the process of career development occurs in preadolescent children. It is clear that there exists a need for the implementation of credible and sustainable career education programs in schools across South Africa in order to encourage and facilitate career exploration during the developmental stage of childhood
Cognitive Load Effect on Moral Decision Making
Cognitive Load Effect on Moral Decision Making Elise Crause, Merry Bailey, Liz Eisenga, Caroline Hopper Choices are made each day to determine the outcome of our lives. To better understand the human process of decision making, philosophers and psychologists have examined moral dilemmas. Cognitive load is a type of stress that alters decision-making and the likelihood of choosing a self-motivated behavior over a behavior that benefits another person or group. For this study, moral dilemmas were given in sets of two before and after a cognitive-load-inducing task. The cognitive-load-inducing task required participants to verbally answer subtraction problems until the answer was correct or time had run out, and the level of stress was measured using two physiological predictors of stress, heart rate and skin conductivity. Our study aimed to determine the effect of an increased cognitive load on the level of selfishness that the participants exhibited when making decisions for a series of moral dilemmas. We conducted our research through the measures of moral dilemmas, heart rate, and skin conductance (Bauer et al., 2022)
