"They're All Sort of Fake, Not Real": An Exploratory Study of Who Young Girls Look Up To

The purpose of this qualitative study was to explore the phenomenon of role models for younger girls. Girls aged 5 to 12 years were asked who they chose to look up to, how significant their role models were to them, why they had chosen them and if they thought they thought that they could achieve their chosen model‟s achievements. Socio-cultural framework provides a useful perspective for understanding the significance of role models as they act as powerful transmitters and reinforcers of the tenets of socialization. In Social Cognitive Theory, it is claimed that children largely learn through modelling, observing and imitating significant others. Interview and task sessions including a field-mapping activity and the sorting of peer-generated photographs were conducted with 12 girls aged from 5 to 12 years from one urban school. In analysis of the interview data, it was found that family members or family substitutes were the most significant people that these girls chose and, despite the alleged pressure from popular culture, young girls in this study were able to make discerning judgements about the „hollowness‟ of characters of popular culture. They identified skills or attributes that their role models demonstrated rather than physical attractiveness, their popularity or the amount of money their fame had brought them. This study is a valid representation of what mattered to a group of young girls at one specific point in time and could indicate the value of further investigation of how to maximize the benefits of role models for young girls.
Icelandic as a second language: a longitudinal study of language knowledge and processing by school-age children

Abstract School-age children (n=39) acquiring Icelandic as a second language were tested yearly over three years on Icelandic measures of language knowledge and language processing. Comparison with native speaker norms revealed large and significant differences for the great majority of the children. Those who scored within the normal monolingual range had a mean length of residence (LOR) of close to 8 years and had arrived to the country at an early age. Raw test scores revealed significant improvement across test times. However, the rate of learning did not occur sufficiently fast for the gap relative to native speakers to diminish over time. Effects of age at arrival and LOR were difficult to tease out. However, children arriving to the country in adolescence performed consistently less well than children with the same LOR arriving in mid childhood. In spite of low scores on standardized tests of language knowledge, the L2 learners scored uniformly high on an Icelandic test of nonword repetition. The acquisition of Icelandic as an L2 appears to occur at a slower rate than the L2 acquisition of English. This may be related to the grammatical complexity of the language as well as to the low global economic value of the Icelandic language.
Moment Invariants in Image Analysis

This paper aims to present a survey of object recognition/classification methods based on image moments. We review various types of moments (geometric moments, complex moments) and moment-based invariants with respect to various image degradations and distortions (rotation, scaling, affine transform, image blurring, etc.) which can be used as shape descriptors for classification. We explain a general theory how to construct these invariants and show also a few of them in explicit forms. We review efficient numerical algorithms that can be used for moment computation and demonstrate practical examples of using moment invariants in real applications. Keywords—Object recognition, degraded images, moments, moment invariants, geometric invariants, invariants to convolution, moment computation.
Lateral Hypothalamus Contains Two Types of Palatability-Related Taste Responses with Distinct Dynamics

The taste of foods, in particular the palatability of these tastes, exerts a powerful influence on our feeding choices. Although the lateral hypothalamus (LH) has long been known to regulate feeding behavior, taste processing in LH remains relatively understudied. Here, we examined single-unit LH responses in rats subjected to a battery of taste stimuli that differed in both chemical composition and palatability. Like neurons in cortex and amygdala, LH neurons produced a brief epoch of nonspecific responses followed by a protracted period of taste-specific firing. Unlike in cortex, however, where palatability-related information only appears 500 ms after the onset of taste-specific firing, taste specificity in LH was dominated by palatability-related firing, consistent with LH's role as a feeding center. Upon closer inspection, taste-specific LH neurons fell reliably into one of two subtypes: the first type showed a reliable affinity for palatable tastes, low spontaneous firing rates, phasic responses, and relatively narrow tuning; the second type showed strongest modulation to aversive tastes, high spontaneous firing rates, protracted responses, and broader tuning. Although neurons producing both types of responses were found within the same regions of LH, cross-correlation analyses suggest that they may participate in distinct functional networks. Our data shed light on the implementation of palatability processing both within LH and throughout the taste circuit, and may ultimately have implications for LH's role in the formation and maintenance of taste preferences and aversions.
Tax education in the UK: a survey of tax courses in undergraduate accounting degrees

This paper presents the results of a postal survey designed to examine the teaching of taxation in UK universities. The project looks at taxation in undergraduate accounting degree programmes and adopts an objective centred focus. The principal aim of the survey was to examine the relationships between some characteristics of individual tax courses, including the course objectives and coverage, staffing, teaching and assessment methods, in an attempt to draw some conclusions on the nature of tax education in UK accounting degrees. The results of the survey and consequent analysis may provide taxation and accounting educators, professional bodies and researchers into accounting education with an insight into approaches to, and methods used in, taxation teaching. It may also present a framework for comparative international research in tax education.
A Study of Barbadian School Personnel Attitudes on Coping with Grief in the Public Schools

Public school personnel are in a unique position to assist grieving children, however preparation to meet this need is not typically included in teacher training and only minimally in counsellor training. This study replicated a previous study (Reid and Dixon, 1999) with US teachers which was a replication of a study conducted with a sample of early childhood teachers (Pratt et al., 1987) while also including the 'Death Attitude Profile Revised (DAP-R)' (Wong et al., 1994). With a sample collected in Barbados, West Indies, this study established school personnel attitudes toward death and dying and their self-perceived ability to assist grieving students. The findings are compared with the findings from the original study by Pratt et al. (1987), the findings of Reid and Dixon (1999), along with norms for the DAP-R established by Wong et al. (1994). The findings indicate the need and desire for further preparation for Barbadian school personnel in dealing with bereaved children.
Timing and Sequence of Brain Activity in Top-Down Control of Visual-Spatial Attention

Recent brain imaging studies using functional magnetic resonance imaging (fMRI) have implicated a frontal-parietal network in the top-down control of attention. However, little is known about the timing and sequence of activations within this network. To investigate these timing questions, we used event-related electrical brain potentials (ERPs) and a specially designed visual-spatial attentional-cueing paradigm, which were applied as part of a multi-methodological approach that included a closely corresponding event-related fMRI study using an identical paradigm. In the first 400 ms post cue, attention-directing and control cues elicited similar general cue-processing activity, corresponding to the more lateral subregions of the frontal-parietal network identified with the fMRI. Following this, the attention-directing cues elicited a sustained negative-polarity brain wave that was absent for control cues. This activity could be linked to the more medial frontal–parietal subregions similarly identified in the fMRI as specifically involved in attentional orienting. Critically, both the scalp ERPs and the fMRI-seeded source modeling for this orienting-related activity indicated an earlier onset of frontal versus parietal contribution (∼400 versus ∼700 ms). This was then followed (∼800–900 ms) by pretarget biasing activity in the region-specific visual-sensory occipital cortex. These results indicate an activation sequence of key components of the attentional-control brain network, providing insight into their functional roles. More specifically, these results suggest that voluntary attentional orienting is initiated by medial portions of frontal cortex, which then recruit medial parietal areas. Together, these areas then implement biasing of region-specific visual-sensory cortex to facilitate the processing of upcoming visual stimuli.
The Governance Role of Audit Committees: Reviewing a Decade of Evidence

Even though audit committees have traditionally been a key component of corporate governance regulation, the last decade has witnessed a greater emphasis on audit committee regulation and a parallel intensification of academic research on the subject. This review synthesizes recent empirical research seeking to investigate various aspects of audit committees’ governance role. The review is structured around current regulatory expectations of audit committees seeking to document the extent to which specific characteristics of good practice influence various components of audit committee effectiveness. It is found that larger and more independent audit committees as well as those with financial expertise are more likely to seek a higher level of external audit coverage and assurance. There is also evidence that more independent audit committees are associated with the purchase of lower levels of non‐audit services from auditors, thereby seeking to preserve the independence of the external audit process. There seems a consensus that more independent audit committees and those with greater accounting/financial expertise have a positive impact on the quality of financial statements. Evidence on the stock market reaction to audit committee issues suggests that investors both welcome the presence of audit committees and react positively when members are appointed with relevant expertise. It is also found that internal auditors view certain audit committee characteristics, specifically independence, expertise and frequency of meetings, as leading to more effective audit committee performance. In summary, therefore, this review documents a significant amount of evidence offering support to current regulations concerning the desired characteristics of audit committees.
On-Off Random Access Channels: A Compressed Sensing Framework

This paper considers a simple on-off random multiple access channel, where n users communicate simultaneously to a single receiver over m degrees of freedom. Each user transmits with probability lambda, where typically lambda n < m << n, and the receiver must detect which users transmitted. We show that when the codebook has i.i. d. Gaussian entries, detecting which users transmitted is mathematically equivalent to a certain sparsity detection problem considered in compressed sensing. Using recent sparsity results, we derive upper and lower bounds on the capacities of these channels. We show that common sparsity detection algorithms, such as lasso and orthogonal matching pursuit (OMP), can be used as tractable multiuser detection schemes and have significantly better performance than single-user detection. These methods do achieve some near-far resistance but--at high signal-to-noise ratios (SNRs)--may achieve capacities far below optimal maximum likelihood detection. We then present a new algorithm, called sequential OMP, that illustrates that iterative detection combined with power ordering or power shaping can significantly improve the high SNR performance. Sequential OMP is analogous to successive interference cancellation in the classic multiple access channel. Our results thereby provide insight into the roles of power control and multiuser detection on random-access signalling.
Process Dissociation Procedure: Double Dissociations following Divided Attention and Speeded Responding

The validity of the process dissociation procedure was examined by manipulating attention and speed of responding in a recognition task. Both manipulations were expected to decrease the probability of controlled memory processes, c, while leaving the probability of automatic memory processes, a, unaffected. In order to estimate c and a, a multinomial processing tree model was fitted to the data. Contrary to expectation, a double dissociation (i.e.a decrease inc coupled with an increase in a) was obtained, suggesting that a does not accurately measure the probability of automatic processes. The results are discussed with reference to the independence assumption in the process dissociation procedure.
The Association of Sociodemographic Factors and Patient Attitudes on Influenza Vaccination Rates in Older Persons

Background To determine how patient attitudes, beliefs, knowledge, and sociodemographic characteristics relate to influenza vaccine acceptance in an older patient population. Methods We conducted a mail survey of patients enrolled in a geriatrics clinic at a university‐affiliated county hospital in Seattle, WA. We surveyed senior citizens’ demographic background, health status, previous experiences, and beliefs about influenza and influenza vaccine. We determined the vaccination rates for influenza season 2001–2002 stratified by race, other sociodemographic factors, and attitudes toward influenza vaccination. Results Surveys were mailed to 572 enrollees in SeniorCare Clinic. Three hundred twenty‐four (57%) responded to the survey, 256 (79%) of whom reported receipt of influenza vaccination. Influenza vaccination rates did not vary significantly by race in this patient population: 80% for white persons, 70% for black persons, and 84% for Asians. Receipt of vaccination was associated with survey responses that indicated a discussion about the influenza shot with a health care provider and a positive attitude toward the influenza shot. History of side effects and negative attitude toward the influenza shot were associated with failure to receive the vaccine. Conclusions In patients served by a university‐affiliated geriatrics clinic, we found no statistically significant difference in influenza vaccination rate between white persons and other racial groups. Attitudes, beliefs, knowledge, and prior experiences toward the influenza shot were predictors of influenza vaccination. Physician recommendation and patient participation strongly correlated with vaccination acceptance.
Isolation and Characterization of Anaerobic Bacteria for Symbiotic Recycling of Uric Acid Nitrogen in the Gut of Various Termites

Recycling of the nitrogenous waste uric acid (UA) of wood-feeding termites by their gut bacteria is one of the significant aspects of symbiosis for the conservation of nitrogen sources. Diverse anaerobic UA-degrading bacteria comprising 16 species were isolated from the gut of eight termite species, and were assigned to Clostridia, Enterobacteriaceae, and low G+C Gram-positive cocci. UA-degrading Clostridia had never been isolated from termite guts. UA-degrading ability was sporadically distributed among phylogenetically various culturable anaerobic bacteria from termite guts. A strain of Clostridium sp. , which was commonly isolated from three termite species and represented a probable new species in cluster XIVa of clostridia, utilized UA as a nitrogen source but not as a sole carbon and energy source. This feature is in clear contrast to that of well-studied purinolytic clostridia or previously isolated UA degraders from termite guts, which also utilize UA as a sole carbon and energy source. Ammonia is the major nitrogenous product of UA degradation. Various purines stimulated the growth of this strain when added to an otherwise growth-limiting, nitrogen poor medium. The bacterial species involved the recycling of UA nitrogen in the gut microbial community of termites are more diverse in terms of both taxonomy and nutritional physiology than previously recognized.
Glasgow’s Ellis Island? The integration and stigmatisation of Govanhill’s Roma population

This paper examines the contemporary situation of different central and Eastern European Roma communities who are currently living in Govanhill, Glasgow. Although adopting a microsociological and ethnographic approach, the wider European and UK political and policy context is discussed and broader structural factors, surrounding migration for example, are not overlooked. The primary focus of ongoing fieldwork in Govanhill is an attempt to witness and account for experiences and understandings of integration and stigmatisation of Roma communities, drawing on the work of Howard Becker, Erving Goffman and Richard Yarwood to assist the analysis. Theoretically and methodologically, the paper embraces an intersectional approach, including reference to the work of feminists such as Kathy Davis and Mari Matsuda. Such an approach is a means of ensuring that issues of class and gender, alongside ethnicity, are documented and appreciated when examining the situation of Roma vis-a-vis identity, integration and community interactions. In particular, various issues around welfare and social policy provision stand out as being principle concerns for Roma communities and service providers in Govanhill. Data from Glasgow illustrates that accommodation, employment and education are all key areas demanding further investigation to improve access, take-up and delivery of services. Responses to some of these urban policy challenges are addressed with evidence to support the argument that some successes are apparent, although there is still much work still to be done. It is notable that some of the most successful ‘on-the-ground’ projects are Roma-led, working in partnership with Glasgow City Council and other public and third sector agencies.
Communication Accommodation: Law Enforcement and the Public

While there is a burgeoning literature on diverse aspects of intergroup communication and some attention to media depictions of police officers and policing, very little research addresses communicative dimensions of police-civilian encounters. This is important to the extent that while it has been estimated that the vast amount of police training is devoted to physical compliance issues, 98% of actual law enforcement practice revolves around communicating with the public and its safety needs. Thus, the communication between police officers and civilians warrants examination. In this chapter, we overview the separate literatures on attitudes toward the police and communication accommodation theory. The findings of three studies are presented exploring the role of accommodation, alongside socio-demographic and other variables, in predicting attitudes toward police. The three studies encompass three different populations: English-speaking adults, Spanish-speaking adults, and university students. Analyses reveal similar results across the samples. In general, accommodation by officers predicts civilians’ rating of officer performance as well as satisfaction when interacting with the police. These findings suggest that more attention should be directed at developing communication skills in general and accommodative ones in particular.
A bi-hemispheric neuronal network model of the cerebellum with spontaneous climbing fiber firing produces asymmetrical motor learning during robot control

To acquire and maintain precise movement controls over a lifespan, changes in the physical and physiological characteristics of muscles must be compensated for adaptively. The cerebellum plays a crucial role in such adaptation. Changes in muscle characteristics are not always symmetrical. For example, it is unlikely that muscles that bend and straighten a joint will change to the same degree. Thus, different (i.e., asymmetrical) adaptation is required for bending and straightening motions. To date, little is known about the role of the cerebellum in asymmetrical adaptation. Here, we investigate the cerebellar mechanisms required for asymmetrical adaptation using a bi-hemispheric cerebellar neuronal network model (biCNN). The bi-hemispheric structure is inspired by the observation that lesioning one hemisphere reduces motor performance asymmetrically. The biCNN model was constructed to run in real-time and used to control an unstable two-wheeled balancing robot. The load of the robot and its environment were modified to create asymmetrical perturbations. Plasticity at parallel fiber-Purkinje cell synapses in the biCNN model was driven by error signal in the climbing fiber (cf) input. This cf input was configured to increase and decrease its firing rate from its spontaneous firing rate (approximately 1 Hz) with sensory errors in the preferred and non-preferred direction of each hemisphere, as demonstrated in the monkey cerebellum. Our results showed that asymmetrical conditions were successfully handled by the biCNN model, in contrast to a single hemisphere model or a classical non-adaptive proportional and derivative controller. Further, the spontaneous activity of the cf, while relatively small, was critical for balancing the contribution of each cerebellar hemisphere to the overall motor command sent to the robot. Eliminating the spontaneous activity compromised the asymmetrical learning capabilities of the biCNN model. Thus, we conclude that a bi-hemispheric structure and adequate spontaneous activity of cf inputs are critical for cerebellar asymmetrical motor learning.
Survey on use of palliative radiotherapy in hospice care.

PURPOSE Radiation oncologists and hospice professionals both provide end-of-life care for oncology patients, and little has been written about the interface between these two groups of specialists. Hospice professionals were surveyed to assess the perceived need for palliative radiotherapy in the hospice setting, to investigate factors that limit the access of hospice patients to radiotherapy, and to suggest areas of future collaboration on education, research, and patient advocacy. PATIENTS AND METHODS Members of the National Hospice and Palliative Care Organization (NHPCO) and American Society for Therapeutic Radiology and Oncology jointly authored a questionnaire to investigate the beliefs of hospice professionals toward the use of radiotherapy for oncology patients in hospice. The questionnaire was distributed to all NHPCO member institutions, and the results were compiled and statistically analyzed. RESULTS Four hundred eighty of more than 1,800 surveyed facilities responded to the questionnaire. The findings suggest that the majority of hospice professionals feel that radiotherapy is important in palliative oncology and that radiotherapy is widely available in the United States. Yet less than 3% on average of hospice patients served by hospices responding to the survey actually received radiotherapy in 2002. The most common barriers to radiotherapy in hospice care include radiotherapy expense, transportation difficulties, short life expectancy, and educational deficiencies between the specialties. CONCLUSION Multiple barriers act to limit the use of palliative radiotherapy in hospice care. Finding ways to surmount these obstacles will provide opportunity for improvement in the end-of-life care of cancer patients.
