Student Teachers in the Classroom: Associate Teachers' Perspective.

This collaborative research project involved both dassroom teachers and a member of an education faculty as researchers. Associate teachers describe both the benefits and drawbacks of having a student teacher in their classroom during their teaching practicum. The nature of the relationship between student teachers and associate teachers is made dearer by identifying these benefits and drawbacks, considering the factors they perceive as stressful, and examining the coping strategies they use or recommend for dealing with stress. By involving those who have daily access, extensive expertise, and a clear stake in improving the teaching practicum with a formaI way to make their knowledge part of the literature, it was ensured that the questions and issues that were important to the associate teachers were addressed.

Sports-related correlates of disordered eating a comparison between aesthetic and ballgame sports

Prevalence rates for disordered eating vary between different types of sports (Sundgot-Borgen & Torstveit, 2004). In this study, athletes of sports with a high risk and low risk for disordered eating were compared regarding potential sports-related risk factors for disordered eating. One hundred and seventy-one aesthetic and ballgame sports athletes participated in this study (mean age 14.1 +/- 1.8 years). Aesthetic sports athletes reported more disordered eating behaviors, sports-related body dissatisfaction, a greater desire to be leaner to improve sports performance and greater social pressure from the sports environment than did ballgame sports athletes. Emotional distress resulting from missed exercise sessions and the desire to be leaner to improve sports performance predicted disordered eating in both sport types. The results suggest that the kinds of risk factors for disordered eating are equal among sport types, but some potential risk factors are more prevalent in aesthetic sports.
Conservative Treatment of a Patient with Epidermolysis Bullosa Presenting as Bart Syndrome: A Case Report

We presented a case of a newborn male with aplasia cutis congenita on the lower limb. The case was treated with conservative method. As for the conservative treatment, daily hydrodebridement with 1/200 diluted povidone-iodine and serum physiologic was performed, followed by closure of the wound with a dexpanthenol + chlorhexidine + fusidic acid-impregnated sterile gauze bandage. the followup that occured after three weeks, the wound was completely epithelialized, but a hypopigmented scar remained in the limb.
Clinical Utility of Amyloid Imaging in a Complex Case of Corticobasal Syndrome Presenting with Psychiatric Symptoms

Clinical indications of amyloid imaging in atypical dementia remain unclear. We report a 68-year-old female without past psychiatric history who was hospitalized for auditory hallucinations and persecutory delusions associated with cognitive and motor deficits. Although psychotic symptoms resolved with antipsychotic treatment, cognitive and motor impairments remained. She further showed severe visuoconstructive and executive deficits, ideomotor apraxia, elements of Gerstmann’s syndrome, bilateral agraphesthesia and discrete asymmetric motor deficits. Blood tests were unremarkable. Structural brain imaging revealed diffuse fronto-temporo-parietal atrophy, which was most severe in the parietal regions. Meanwhile, FDG-PET suggested asymmetrical fronto-temporo-parietal hypometabolism, with sparing of the posterior cingulate gyrus. A diagnosis of possible corticobasal syndrome (CBS) was made. Amyloid-PET using the novel tracer NAV4694 was ordered, and revealed significant deposition of fibrillar amyloid (SUVR 2.05). The primary diagnosis was CBS with underlying Alzheimer pathology and treatment with a cholinesterase inhibitor was initiated. Determination of underlying pathological CBS subtype is not simple even when based on extensive investigation including clinical presentation, atrophy patterns on MRI, and regional hypometabolism on FDG-PET. By contrast, amyloid imaging quickly confirmed Alzheimer pathology, and allowed rapid initiation of treatment in this complex case with early psychiatric symptoms. This case study illustrates the clinical utility of amyloid imaging in the setting of atypical cases seen in a tertiary memory clinic.
The changing landscape of advanced and castration resistant prostate cancer: latest science and revised definitions.

INTRODUCTION One fifth of men with newly diagnosed prostate cancer present with locally advanced or metastatic disease. Androgen deprivation therapy (ADT) is the standard systemic therapy in these patients. Despite initial response, essentially all patients will develop castration resistant prostate cancer (CRPC). In this review, we will discuss the revised definitions of CRPC and the latest understanding of the biology of the androgen/androgen receptor axis in the development of advanced prostate cancer. MATERIALS AND METHODS A systematic literature review was conducted via electronic database articles based on title, abstract, study format, and content. The majority of selected articles were published between 1992 and 2013. Older studies were included selectively if historically relevant. RESULTS Prostate cancer becomes castration resistant through numerous pathways, including androgen and androgen receptor (AR) dependent mechanisms as well as ligand and AR independent pathways. Therefore the terms androgen-insensitive and hormone-refractory should be avoided and replaced by the term castration resistant. Recent advances in understanding molecular mechanisms of castration resistance have led to development of novel CRPC therapeutics. CONCLUSIONS CRPC remains an incurable disease. Further understanding of the pathways involved in castration resistance will set the basis for development of therapies to increase survival in these patients.
The Decimation Process in Random k-SAT

Non-rigorous statistical mechanics ideas have inspired a message passing algorithm called Belief propagation guided decimation for finding satisfying assignments of random k-SAT instances. This algorithm can be viewed as an attempt at implementing a certain thought experiment that we call the decimation process. In this paper we identify a variety of phase transitions in the decimation process and link these phase transitions to the performance of the algorithm.
Improving Situational Awareness in RoboFlag

Situational awareness in competitive games has started to attract increasing attention in the control community. It studies how a robot identifies, understands and predicts the significant factors around it, which is essential for effective decision making and performance in any complex and dynamic environment. In this thesis, we investigate the situational awareness problems in RoboFlag, a highly dynamic testbed that comprises a mixture of offense and defense games between two robotic teams. To improve situational awareness in RoboFlag, we want to solve two main problems. (1) Real-time position estimation given limited sensing capability. (2) Optimal decision-making strategy based on position estimation. Monte Carlo Localization (MCL), a statistical method based on particle representations of probability densities moving sequentially in discrete time, has been shown as an effective and time-efficient method for reliable position estimation, especially when the dynamics of the system and the environment are nonlinear and non-Gaussian, such as RoboFlag. In this thesis, a dynamic weight map, Hospitability Map (H-Map), that measures the ability of a target to move and maneuver at each location of the field, has been applied to MCL to enhance the efficiency and accuracy of MCL in resampling phase. Empirical results illustrate that H-Map based MCL method improves situational awareness in Roboflag by providing reliable position prediction and enhancing decisionmaking performance.

Minimality and other properties of the width-w nonadjacent form

Let w ≥ 2 be an integer and let D w be the set of integers that includes zero and the odd integers with absolute value less than 2 w-1 . Every integer n can be represented as a finite sum of the form n = Σa i 2 i , with a i ∈E D w , such that of any w consecutive α i 's at most one is nonzero. Such representations are called width-w nonadjacent forms (w-NAFs). When w = 2 these representations use the digits {0, ±1} and coincide with the well-known nonadjacent forms. Width-w nonadjacent forms are useful in efficiently implementing elliptic curve arithmetic for cryptographic applications. We provide some new results on the w-NAF. We show that w-NAFs have a minimal number of nonzero digits and we also give a new characterization of the w-NAF in terms of a (right-to-left) lexicographical ordering. We also generalize a result on w-NAFs and show that any base 2 representation of an integer, with digits in D w , that has a minimal number of nonzero digits is at most one digit longer than its binary representation.
A model of angle selectivity in area V2 with local divisive normalization

Efficient coding hypothesis states that the goal of sensory system of the brain is to remove redundancies in the sensory input. Several models tried to remove redundancy in the visual input and successfully modeled the functional properties of neurons in the primary visual cortex. However there has been no progress to extend these models to simulate the properties of neurons in extrastriate visual areas. In this paper, we propose that visual cortex tries to remove higher order dependencies in a hierarchical architecture. In each layer a nonlinear mechanism removes redundancies in a local neighborhood. We used the biologically plausible divisive normalization mechanism in a two layer model network to remove nonlinear dependencies in the input. Units in this model can simulate the responses of neurons in area V2 to angle stimuli.
Quantitative functional neuroimaging of cerebral physiology in healthy aging

Functional MRI (fMRI) studies using the BOLD signal are done under the general assumption that the BOLD signal can be used as a direct index of neuronal activation. Studies of cognitive aging often compare BOLD signal amplitude and extent directly between younger and older groups, with the additional assumption that the relationship between neuronal activity and the hemodynamic response is unchanged across the lifespan. However, BOLD signal arises from an ambiguous mixture of changes in oxidative metabolism, blood flow and blood volume. Furthermore, previous studies have shown that several BOLD signal components may be changed during aging. More physiologically-specific information on blood flow and oxidative metabolism would allow a better understanding of these signal changes and of the physiological and cognitive changes seen with aging. The work presented here demonstrates techniques to estimate oxidative metabolism at rest and during performance of a task. These techniques are extensions of previous calibrated fMRI methods and the first method presented is based on a generalization of previous models to take into account both arbitrary changes in blood flow and blood O2 content. The improved robustness and accuracy of this method, when used with a combined hypercapnia and hyperoxia breathing manipulation, is demonstrated in visual cortex and grey matter. The second technique presented builds on the generalization of the model and uses a combination of breathing manipulations including hypercapnia, hyperoxia and both simultaneously, to obtain experimentally-determined values of resting oxygen extraction fraction and oxidative metabolism. In the second part of this thesis, agerelated vascular and metabolic changes are explored in a group of younger and older adults using a calibrated fMRI framework with a hypercapnia breathing manipulation and a modified Stroop task. Changes in baseline blood flow, vascular reactivity to the CO2 challenge and calibration parameter M were identified in the older participants. Potential biases in BOLD signal measurements in older adults arising from these physiological changes are discussed. Finally, the relationship between these cerebral changes and performance on the modified Stroop task, central vascular health and cardiovascular fitness are explored. The results of this

Severe Developmental Defects, Hypersensitivity to DNA-Damaging Agents, and Lengthened Telomeres in Arabidopsis MRE11 Mutants Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.005959.

The Mre11 protein is essential for the long-term genetic stability of the cell and acts to ensure the efficient repair of DNA damage. Vertebrate cells lacking Mre11 function are not viable. However, we report here that this is not the case in the model plant Arabidopsis. We have isolated two different Arabidopsis lines containing a T-DNA copy integrated at a different point in the MRE11 gene (AtMRE11). Both mutant plant lines were hypersensitive to DNA-damaging treatments but exhibited strikingly different developmental phenotypes. Furthermore, we also observed lengthened telomeres in these plant lines, showing that AtMre11 is involved in telomere maintenance. Thus, the lines we have isolated are unique tools with which to study in detail the role of AtMre11 in the mature plant.
A New International Division of Labour in Europe: Outsourcing and Offshoring to Eastern Europe

Europe is reorganizing its international value chain. I document these changes in Europe’s international organization of production with new survey data of Austrian and German firms investing in Eastern Europe. I show estimates of the share of intrafirm trade between Austria or Germany on the one hand and Eastern Europe on the other. Furthermore, I present empirical evidence of the drivers of the new division of labor in Europe. I find among other things that falling trade costs and reduced levels of corruption as well as improvements in the contracting environment in Eastern Europe are affecting the level of intrafirm imports from that region. These factors also favor outsourcing over offshoring. In contrast, low organizational costs of hierarchies and large costs of holdup (when there are no alternative investors in Old Europe or no alternative suppliers in Eastern Europe) favor offshoring over outsourcing. Tax holidays granted by host countries in Eastern Europe also mildly affect the organizational choice.
A Comparison of MIMO Receiver Structures for 802.11N WLAN - Performance and Complexity

This paper compares the performance and complexity of various MIMO receiver structures for 802.11n WLAN systems, including linear approaches such as MMSE and ZF, and iterative detection and decoding using list sphere decoding. Optimal beam steering with the low-complexity MMSE receiver is shown to outperform the computationally-expensive list sphere decoder receiver with an uninformed transmitter
Artificial Parthenogenesis

THE development of biology into an experimental science is nowhere better illustrated than in the important researches on artificial parthenogenesis which we owe largely to Jacques Loeb, and biologists will welcome heartily the little book in which this distinguished author gives an account of the subject. Prof. Loeb informs us that the object of his investigations was to transfer the problem of the fertilisation (Entwicklungserregung) of the animal egg from the domain of morphology to that of physical chemistry. He recalls the fact that it is only about sixty years since it was first firmly established that the animal earg-with the exception of a few cases-can only develop into an embryo after fertilisation by the entrance of a spermatozoon. Various interpretations have been placed upon this process. O. Hertwig maintained that the essential feature of fertilisation was the union of the male and female pronuclei in the egg-cell, and the observation of this union was undoubtedly of the greatest importance, especially from the point of view of the theory of heredity, but it gave us no real insight into the nature of the stimulus which evokes as its response the segmentation of the egg. Boveri, indeed, maintained that the union of the two pronuclei had nothing to do with providing this stimulus, and was able to show that an enucleated egg may develop after fertilisation by a spermatozoon. According to Boveri the centrosome is the organ of cell-division, and the unfertilised egg cannot develop because the centrosome is wanting. A new centrosome is introduced by the spermatozoon, and then cell-division or segmentation commences.
Functional Aspects of Silencing and Transient Expression of psb S in Nicotiana benthamiana

MicroRNA-based gene silencing is a functional genomics tool for a wide range of eukaryotes. As a basis for broader application of virus-induced gene silencing (VIGS) to photosynthesis research, we employed a tobacco rattle virus (TRV) vector to silence expression of the nuclear psbS gene in Nicotiana benthamiana. The 22-kiloDalton psbS protein is essential for xanthophyll- and H+-dependent thermal dissipation of excitation in higher plants widely known as nonphotochemical quenching (NPQ). Controls treated with the TRV-VIGS vector containing a bacterial chloramphenicol resistance gene as the silencing target were included to test for non-silencing effects of the viral vector system. PsbS protein was undetectable and both psbS mRNA transcript levels and NPQ capacity were dramatically reduced in new leaf tissue of VIGS-psbS plants only. Photosynthetic performance in TRV-VIGS-treated and uninfiltrated plants was assessed by application of CO2 exchange, chlorophyll fluorescence, and in vivo absorbance changes at 810 nm. TRV-VIGS caused a mild stress based on pigment content and light absorption characteristics in some cases. To assess transient complementation of NPQ, the endogenous psbS gene was silenced using only the transit sequence in the TRV vector followed by Agrobacterium-mediated transient expression of a modified gene consisting of an altered transit sequence fused to the native mature protein sequence. Nevertheless, NPQ in infused fully expanded leaves that expressed this re-introduced form was not fully restored indicating the possible importance of psbS incorporation prior to formation of grana stacks.
Highly tapered, uniform phased horn based on variable impedance lens effect

This paper demonstrates the properties of an H-plane horn antenna with its characteristics improved using the principle of variable surface impedance. Modifying the surface boundary conditions on one surface of the parallel plate structure is possible by using printed patches of variable size. By doing so, surface impedance profile which corresponds to Luneburg law can be realized. Luneburg lens designed in this way can then be easily implemented inside planar horn antennas to improve their characteristics. The results of this idea are demonstrated using full-wave simulations and show that it is possible to obtain higher horn directivity and significantly reduce the size of the horn within the operational band of the designed Luneburg lens.
