Differences in Faculty Development Needs: Implications for Educational Peer Review Program Design

The purpose of faculty development in terms of the educational role is to assist faculty in becoming better educators. Educational peer review (EPR) is one method of faculty development. This article is based on a study that explored the different development needs of nursing faculty within a school of nursing at an Ontario university. The study explored on three variables of interest: level of skill acquisition, type of faculty appointment, and type of teaching. A qualitative research design in the case-study tradition was employed. Findings indicated that faculty challenges could be grouped into three themes: job knowledge, skills development, and systems challenges. Job knowledge and skills development challenges varied by level of skill acquisition and type of teaching, while identiﬁ ed systems challenges were related to type of appointment. A ﬂ exible EPR program that allows for some customization may lead to an increased ability to meet individual faculty development needs and greater faculty buy-in. Le but du developpement de faculte dans le role educatif est d’aider la faculte a devenir des meilleurs educateurs. L’evaluation educative par les pairs (EEP) est une methode de developpement de faculte. Cette etude a explore les differences dans les besoins de developpement de faculte d’une faculte d’inﬁ rmiers dans une ecole d’inﬁ rmiers a une universite d’Ontario basee sur trois variables d’interet : niveau d’acquisition de competence, type de designation de faculte et type d’enseignement. Un protocole de recherche qualitatif dans la tradition d’etude de cas a ete utilise. Les resultats ont indique que des deﬁ s de faculte pourraient etre groupes dans trois themes: la connaissance de travail, le developpement de competences et les deﬁ s du systeme. La connaissance de travail et les deﬁ s de developpement de competences ont varie par le niveau de l’acquisition de competence et le type d’enseignement, alors que des deﬁ s du systeme identiﬁ es etaient lies au type de designation. Un programme ﬂ exible de EEP, qui tient compte de personnalisation, peut mener a la capacite accrue de repondre aux differents besoins de developpement de faculte et au plus d’acceptation de faculte.
Nonparametric Classifier of Buried Mines Using MWIR Images

Abstract : Under Army SBIR Phase I funding, we have developed a nonparametric buried mine classifier using MWIR images. We start with our new image segmentation method based on the wavelet transform. Instead of thresholding the original MWIR images, we first apply the wavelet transform to MWIR image and estimate a threshold value in the corresponding wavelet domain. The small wavelet coefficients are associated with the noise and background clutters appeared in the original image. We then map this threshold in the wavelet domain back to MWIR image domain by applying the inverse wavelet transform. This new threshold is subsequently used to segment the MWIR images and extract small image chips (patches) containing potential buried mines for further detection and classification. In order to perform the statistical classification, we have applied Kolmogorov-Smirnov (KS) test, a powerful nonparametric statistical hypothesis test procedure. One major advantage of using KS test for buried mine detection is that we don't need to make any assumptions of the underlying statistical distributions associated with the cluster intensity variation profiles.
Endoplasmic Reticulum Stress Is Involved in the Response of Human Laryngeal Carcinoma Cells to Carboplatin but Is Absent in Carboplatin-Resistant Cells

The major obstacle of successful tumor treatment with carboplatin (CBP) is the development of drug resistance. In the present study, we found that following treatment with CBP the amount of platinum which enters the human laryngeal carcinoma (HEp2)-derived CBP-resistant (7T) cells is reduced relative to the parental HEp2. As a consequence, the formation of reactive oxidative species (ROS) is reduced, the induction of endoplasmic reticulum (ER) stress is diminished, the amount of inter- and intrastrand cross-links is lower, and the induction of apoptosis is depressed. In HEp2 cells, ROS scavenger tempol, inhibitor of ER stress salubrinal, as well as gene silencing of ER stress marker CCAAT/enhancer-binding protein (CHOP) increases their survival and renders them as resistant to CBP as 7T cell subline but did not influence the survival of 7T cells. Our results suggest that in HEp2 cells CBP-induced ROS is a stimulus for ER stress. To the contrary, despite the ability of CBP to induce formation of ROS and activate ER stress in 7T cells, the cell death mechanism in 7T cells is independent of ROS induction and activation of ER stress. The novel signaling pathway of CBP-driven toxicity that was found in the HEp2 cell line, i.e. increased ROS formation and induction of ER stress, may be predictive for therapeutic response of epithelial cancer cells to CBP-based therapy.
Empirical and historical perspectives on the growth of Pentecostal-style churches in Malaysia, Singapore and Hong Kong

This article considers the growth of Pentecostal-style churches in Southeast Asia, and specifically in Hong Kong, Kuala Lumpur and Singapore. It outlines four reasons for the growth that occurred and then, using qualitative and quantitative data in a mixed mode, seeks to test the hypotheses it derives. It concludes that each of the hypotheses remains plausible but notes that contextual factors or major social disruptions undermine any deterministic account.
Adsorption of Simple Benzene Derivatives on Carbon Nanotubes

Abstract : The adsorption of simple benzene derivatives composed of a benzene ring with NO2, CH3, or NH2 functional groups on a semiconducting single-wall carbon nanotube is studied using the density-functional theory within the local-density approximation. The effects of molecular relaxation in the adsorption process are obtained, as well as the adsorption energies and equilibrium distances for several molecular locations and orientations on the surface. We find that all of these benzene derivatives are physisorbed mainly through the interaction of the orbitals of the benzene ring and those of the carbon nanotube. These aromatics do not change significantly the carbon nanotube s electronic structure, and therefore only small changes in the nanotube s properties are expected. This suggests that these benzene derivatives are suitable for noncovalent nanotube functionalization and molecule immobilization on nanotube surfaces.
Multidetector computed tomography angiography in clinically suspected hyperacute ischemic stroke in the anterior circulation: an etiological workup in a cohort of Brazilian patients.

OBJECTIVE The potential of computed tomography angiography (CTA) was assessed for early determination of stroke subtypes in a Brazilian cohort of patients with stroke. METHOD From July 2011 to July 2013, we selected patients with suspected hyperacute stroke (< 6 hours). Intracranial and cervical arteries were scrutinized on CTA and their imaging features were correlated with concurrent subtype of stroke. RESULTS Stroke was documented in 50/106 selected patients (47.2%) based on both clinical grounds and imaging follow-up (stroke group), with statistically significant arterial stenosis and vulnerable plaques on CTA. Intracranial large artery disease was demonstrated in 34% of patients in the stroke group. Partial territorial infarct prevailed (86%) while artery-to-artery embolization was the most common stroke mechanism (52%). CONCLUSION Multidetector CTA was useful for the etiologic work-up of hyperacute ischemic stroke and facilitated the knowledge about the topographic pattern of brain infarct in accordance with its causative mechanism.
Undergraduates' understanding of evolution: ascriptions of agency as a problem for student learning

This paper explores the conceptions of evolutionary processes held by a group of university students (n = 126) before receiving instruction on evolution. We focus on students' linguistic usage in order to speculate about the source of some of the conceptual problems students encounter in this area. A central problem is the tendency ofstudents to ascribe agency when attempting to describe evolutionary processes in a way that contributes to misconceptions. Whilst scientifically accepted notions of natural selection emphasise random processes of genetic mutation and allele recombination during reproduction, leading to variation in populations, many problematic notions held by students seem to suggest adaptive processes that are purposive, even conscious striving for evolutionary progress and advantage. This goal-directedness is often presented as an internal, inherent attributeof individual organisms or of populations of species (a kind of collective consciousness) or, less commonly, externally as a conscious driving force or greater design. We examine responses from undergraduate students to phenomenologically-based probes, designed to investigate undergraduate conceptions of evolution, and inwhich students select the language used to explain the process or mechanism of the phenomenon in question. We speculate about how broader world views in advertently 'leak' into scientific language, encouraging spurious goal-driven accounts of evolution, and how these frustrate appropriate concept formation. We conclude with suggestions that successful teaching of evolution will require both a greater sensitivity to the use of figurativelanguage in science, and explicit attention to how scientific theories of the world differ from other accounts.
The natural history of somatization in primary care

Background. Somatization is often regarded as a chronic disorder. However, empirical studies to support this view and to determine its natural history in primary care are lacking. This paper provides data on the incidence and persistence of current somatization syndrome in a large cross-national sample drawn from 15 sites in 14 countries. Methods. After screening with the General Health Questionnaire, a stratified sample of 5438 primary care patients was interviewed with the Composite International Diagnostic Interview and evaluated for physical health status, self-rated overall health and for occupational disability. Twelve months later, 3204 of the patients completed follow-up interviews. Results. Over a 12-month period, an abridged form of somatization defined as four current symptoms in males and six in females was persistent in 45·9% of the patients. Persistence of syndrome was related to age and to subjective indices of psychological distress at baseline. Persistence was unrelated to depression. The 12-month incidence of the abridged somatization syndrome was 7·1% (95% CI, 6·1–8·3%). Individuals with depression at baseline and those with poor view of their health were more likely to develop new episodes of somatization 12-months later. Conclusion. Somatization syndrome showed considerable change over time. Persistence and onset of somatization were related to both level of psychopathology and health beliefs.
The timing of parimutuel bets

We propose a dynamic model of parimutuel betting that addresses the following three empirical regularities: a sizeable fraction of bets is placed early, late bets are more informative than early bets, and proportionally too many bets are placed on longshots. Exploiting a similarity with Cournot oligopoly, we show that bettors have an incentive to bet early when they are large and act on common information. Bettors who are instead privately informed and small have an incentive to bet at the end without access to the information of the others. Longshots (or favorites) are then less (or more) likely to win than indicated by the market odds.
Kinetic properties of catecholoxidase activity of tarantula hemocyanin

Phenoloxidases occur in almost all organisms, being essentially involved in various processes such as the immune response, wound healing, pigmentation and sclerotization in arthropods. Many hemocyanins are also capable of phenoloxidase activity after activation. Notably, in chelicerates, a phenoloxidase has not been identified in the hemolymph, and thus hemocyanin is assumed to be the physiological phenoloxidase in these animals. Although phenoloxidase activity has been shown for hemocyanin from several chelicerate species, a characterization of the enzymatic properties is still lacking. In this article, the enzymatic properties of activated hemocyanin from the tarantula Eurypelma californicum are reported, which was activated by SDS at concentrations above the critical micellar concentration. The activated state of Eurypelma hemocyanin is stable for several hours. Dopamine is a preferred substrate of activated hemocyanin. For dopamine, a KM value of 1.45 ± 0.16 mm and strong substrate inhibition at high substrate concentrations were observed. Typical inhibitors of catecholoxidase, such as l‐mimosine, kojic acid, tyramine, phenylthiourea and azide, also inhibit the phenoloxidase activity of activated hemocyanin. This indicates that the activated hemocyanin behaves as a normal phenoloxidase.
Optic Neuritis in the Older Chinese Population: A 5-Year Follow-Up Study

Objective This study aims to describe the clinical manifestations and outcomes in a cohort of older Chinese patients. Method A retrospective study of patients aged ≥ 45 years who had a first episode of optic neuritis (ON) between May 2008 and November 2012. Clinical features at onset and last follow-up were analyzed within subgroups (age 45–65 years and age ≥ 65 years). Results 76 patients (99 eyes) were included, of which 58% were females. The mean age at presentation was 55.53 ± 8.29 years (range: 45–83 years). Vision loss was severe at presentation, with initial best corrected vision activity (BCVA) < 20/200 in 93% and final BCVA < 20/200 in 53% of patients at 5-year follow-up. Final BCVA significantly correlated with the initial BCVA and peripapillary retinal nerve fiber layer. At last follow-up, 14.5% were diagnosed with neuromyelitis optica spectrum disorder (NMOSD), 1.3% were diagnosed with multiple sclerosis (MS), 5.2% with chronic relapsing inflammatory optic neuropathy, 1.3% with infectious ON, and 19.7% with autoimmune ON. None of the elderly group (≥65 years) developed NMOSD or MS. Conclusion Chinese patients in the age group ≥ 65 years with ON are less likely to develop NMOSD or MS. Notwithstanding, they had more severe visual loss at onset and poor recovery.

1D-VAR Retrieval of Temperature and Humidity Profiles From a Ground-Based Microwave Radiometer

A variational method to retrieve profiles of temperature, humidity, and cloud is described, which combines observations from a 12-channel microwave radiometer, an infrared radiometer, and surface sensors with background from shortrange numerical weather prediction (NWP) forecasts in an optimal way, accounting for their error characteristics. An analysis is presented of the error budget of the background and observations, including radiometric, modeling, and representativeness errors. Observation errors of some moisture channels are found to be dominated by representativeness, due to their sensitivity to atmospheric variability on smaller scales than the NWP model grid, whereas channels providing information on temperature in the lowest 1 km are dominated by instrument noise. Profiles of temperature and a novel total water control variable are retrieved from synthetic data using Newtonian iteration. An error analysis shows that these are expected to improve mesoscale NWP, retrieving temperature and humidity profiles up to 4 km with uncertainties of 1 K and 40% and 2.8 and 1.8 degrees of freedom for signal, respectively, albeit with poor vertical resolution. A cloud classification scheme is introduced to address convergence problems and better constrain the retrievals. This Bayesian retrieval method can be extended to incorporate observations from other instruments to form a basis for future integrated profiling systems.
POSITIVE ADAPTATION IN LATINO FAMILIES OF CHILDREN WITH DEVELOPMENTAL DISABILITIES: AN INITIAL TEST OF POSITIVE ADAPTATION THEORY

Historically, research on disability and family dynamics drew from Psychology and Medicine. Consequently, eugenics models, grief theory, and other largely decontextualized frameworks of stress and coping were used to explain families of children with disabilities. This is a report of an initial test of a set of ideas the Singer research team has combined in order to explore the cognitive and problem-solving approaches of families of children with disabilities. Our purpose is to propose a contextualized theory for explaining how cultural diversity has an impact on positive adaptation to a child’s disability. This theory addresses the following: 1) attachment; 2) internal and external cultural resistance to stigmas about disability; and 3) perceived informal (family/friends) and formal (professionals) sources of support for positive views about disability and parenting. Sampling Latino families demonstrated how cultural contexts demonstrate a different flavour from majority culture interpretations of these cognitive terms of our proposed theory. Transcripts of the interviews were coded using grounded theory analysis, specifically, the constant comparative method. We discuss the goodness of fit for themes emerging from the coding process with the proposed theory terms. Results confirm attachment, social supports, and cultural resistance as terms for future development of this proposed theory. Keywords: Disability and parenting, positive adaptation, Latinos and disability, culture and disability
POCO: discovery of regulatory patterns from promoters of oppositely expressed gene sets

Functionally associated genes tend to be co-expressed, which indicates that they could also be co-regulated. Since co-regulation is usually governed by transcription factors via their specific binding elements, putative regulators can be identified from promoter sets of (co-expressed) genes by screening for over-represented nucleotide patterns. Here, we present a program, POCO, which discovers such over-represented patterns from either one or two promoter sets. Typical microarray experiments yield up- and down-regulated gene sets that may represent, for example, distinct defense pathways. Assuming that a functional transcription factor cannot simultaneously both up- and down-regulate the gene sets, its binding element should respectively be over- and under-represented in the corresponding promoter sets. This idea is implemented in POCO, which tests the hypothesis that the distributions of a pattern differ among three sets of promoters: up-regulated, down-regulated and randomly-chosen. In the program, pattern discovery is based on explicit enumeration of all possible patterns on the alphabet (A, C, G, T and N). The mean occurrences and SDs of the patterns are estimated using bootstrapping and their significance is assessed using ANOVA F-statistics, Tukey's honestly significantly difference test and P-values.

GestureFlow: QoE-Aware Streaming of Multi-TouchGestures in Interactive Multimedia Applications

With the proliferation of multi-touch mobile devices, such as smartphones and tablets, users interact with devices in non-conventional gesture-intensive ways. As a new way to interact with mobile devices, gestures have been proven to be intuitive and natural with a minimal learning curve, and can be used in interactive multimedia applications. In order for multiple users to collaborate in an interactive manner, we propose that gestures can be streamed in multiple broadcast sessions, with each session corresponding to one of the users as the source of a gesture stream. During the interactive session, the Quality of Experience (QoE) of mobile users hinges upon delays from when gestures are entered by the source to when they are recognized by each of the receivers, which we refer to as gesture recognizing delays. In this paper, we present the design of GestureFlow, a gesture broadcast protocol designed specifically for concurrent gesture streams in multiple broadcast sessions, such that the gesture recognizing delay in each session is minimized. We motivate the effectiveness and practicality of using inter-session network coding, and address challenges introduced by the linear dependence of coded packets. We evaluate our protocol design using an extensive array of real-world experiments on mobile devices, involving a new gesture-intensive interactive multimedia application, called MusicScore, that we developed from scratch.
