Academic misconduct in teaching portfolios

Within academia, clear and standardised communication is vital. From this point of departure, we discuss the trustworthiness of teaching portfolios when used in assessment. Here, misconduct and fraud are discussed in terms of fabrication, falsification, and plagiarism, following the literature on research fraud. We argue that the portfolio’s unclear academic status and confusing standards makes it difficult to define misconduct. We see a risk that the practice of portfolio writing for assessment can lead to misconduct, including downright lies about accomplishments. We conclude that the trustworthiness of teaching portfolios is a responsibility for the academic community as a whole.
Convergence of Vestibular and Visual Self-Motion Signals in an Area of the Posterior Sylvian Fissure

Convergence of visual motion information (optic flow) and vestibular signals is important for self-motion perception, and such convergence has been observed in the dorsal medial superior temporal (MSTd) and ventral intraparietal areas. In contrast, the parieto-insular vestibular cortex (PIVC), a cortical vestibular area in the sylvian fissure, is not responsive to optic flow. Here, we explore optic flow and vestibular convergence in the visual posterior sylvian area (VPS) of macaque monkeys. This area is located at the posterior end of the sylvian fissure, is strongly interconnected with PIVC, and receives projections from MSTd. We found robust optic flow and vestibular tuning in more than one-third of VPS cells, with all motion directions being represented uniformly. However, visual and vestibular direction preferences for translation were mostly opposite, unlike in area MSTd where roughly equal proportions of neurons have visual/vestibular heading preferences that are congruent or opposite. Overall, optic flow responses in VPS were weaker than those in MSTd, whereas vestibular responses were stronger in VPS than in MSTd. When visual and vestibular stimuli were presented together, VPS responses were dominated by vestibular signals, in contrast to MSTd, where optic flow tuning typically dominates. These findings suggest that VPS is proximal to MSTd in terms of vestibular processing, but distal to MSTd in terms of optic flow processing. Given the preponderance of neurons with opposite visual/vestibular heading preferences in VPS, this area may not play a major role in multisensory heading perception.
Ray-optical modeling of simulcast radio propagation channels in tunnels

Simulcast radio propagation channel characteristics inside tunnels are considered in this paper. Based on the image theory of ray optics, a simulcast radio propagation channel in a rectangular tunnel is exactly formulated. As only the field components of horizontal and vertical polarization are of interest in real implementation, the exact formulation is approximated to facilitate the numerical computation. The calculated simulcast radio propagation channels are comparable fairly to measurements at 900 MHz and 2.0 GHz. The validated ray-optical modeling approach is then applied to simulate simulcast radio propagation channel characteristics at 900 MHz and 2.0 GHz to gain deeper insight and better understanding of this type of channels in tunnels. Results show that large fluctuations occur in the capture regions of the distributed antennas for both 900 MHz and 2.0 GHz. The fluctuations in the simulcast regions are larger at 2.0 GHz than at 900 MHz. The root-mean-squared (rms) delay spread is greater in the simulcast regions than in the capture regions of the distributed antennas. This larger delay spread is mainly due to the delay introduced by the transmission medium. Large values of the rms delay spread can be avoided by a careful design of the distance between the distributed antennas.
Preservation of Post Operative Bone Conduction Hearing after Labyrinthine Fistula Repair in Chronic Otitis Media with Cholesteatoma: A Review of 23 Cases

OBJECTIVE: Labyrinthine fistula can lead to hearing loss, dizziness, and intracranial complications. The management of labyrinthine fistula is con troversial, and hearing preservation represents a major challenge. In this study, the authors sought to identify factors related to postoperative bone conduction threshold. MATERIALS and METHODS: This retrospective study was conducted using the clinical records of 23 cases operated on for chronic otitis media with cholesteatoma from 2004-2011. Symptoms, physical examination finings, fistula test results, pre-/postoperative bone conduction results, and high-resolution temporal bone computed tomograpghy and intraoperative findings were evaluated. RESULTS: The most common symptom at presentation was hearing disturbance, and the most commonly affected site was the lateral semicircular canal. High-resolution temporal bone computed tomograpghy was found to be much more precise and effective at fistula detection than the fistula test. CONCLUSION: Postoperative hearing results are not affected by fistula location, size, or number. Complete resection at the site of a cholesteatoma tous labyrinthine fistula is the treatment of choice.
A class E GaN microwave power amplifier accounting for parasitic inductance of transistor

The effects of parasitic inductance of transistor on finite dc-feed inductance type class E microwave power amplifier is analyzed in this letter. We find that the frequency bandwidth can be improved by fully consideration of the output parasitic inductance of transistor. To validate the method, a GaN power amplifier by using the proposed topology is designed for demonstration purpose. Experimental results show that the amplifier is realized from 2.5GHz to 3.5GHz (33.3%) with measured drain efficiency larger than 60%, which show good agreement with the simulated results.

Atopic Eczema/Dermatitis Syndrome and Malassezia

Atopic dermatitis is a chronic multifactorial inflammatory skin disease, which has had a marked increase in prevalence during the last decades. Recently, a new nomenclature was recommended where the term ‘atopic eczema/dermatitis syndrome’ (AEDS) should be used to reflect the heterogeneity in this group of patients and where those patients without measurable IgE reactivity should be classified as either ‘nonallergic AEDS’ or ‘non-IgE-associated allergic AEDS’. For nearly 20 years it has been discussed whether the opportunistic yeast Malassezia, previously designated Pityrosporum, is a contributing factor to AEDS. Today there are several reports that demonstrate specific serum IgE or positive skin prick test and/or atopy patch test reactions to Malassezia in patients with AEDS. Several IgE-binding components have been identified in extracts of Malassezia ranging in molecular mass between 10 and 100 kD. The genes for nine Malassezia allergens with molecular weights ranging from 14 to 36 kD have hitherto been identified and cloned. Six of them are now produced by recombinant techniques and used in diagnostic tests. At present the genus Malassezia is subdivided into seven different species, which all have been isolated from human skin. The respective contribution of different Malassezia spp. to AEDS and in what proportion they share allergens remains to be clarified. We summarize here data that Malassezia can play a role in eliciting and maintaining eczema in patients with AEDS.
Automatic identification and back-transliteration of foreign words for information retrieval

Many foreign words and English words appear in Korean texts, especially in the areas of science and engineering. We recognize two issues related to foreign words, which should be addressed for information retrieval (IR). First, since foreign words are introduced dynamically and not always found in a dictionary, they cause problems in morphological analysis required for indexing. Second, although a foreign word and its origin in the source language like English refer to the same concept, they are erroneously treated as independent index terms. As a way of alleviating the first problem we developed an algorithm that first identifies a phrase containing a foreign word and then extracts the foreign word part from the phrase based on statistical information. For the second problem, we present our method for back-transliteration of a foreign word to its English origin. Finally we report our evaluation results for each of the algorithms and experimental results for their impact on IR effectiveness.
Reconfigurable digital filter based on fractional delay structure and interpolation technique for wider cutoff frequency range

In fractional delay based filters, each unit delay is replaced by a fractional delay structure (FDS) whose delay value determines the cutoff frequency (fc) of the filter. In this paper we present the design of interpolated FDS (IFDS) based filter to overcome the lower and upper limits on fc range of the existing FDS based filter. In the proposed IFDS based filter, the continuously variable fractional delay (CVFD) element is used to replace the unit delay element of the prototype filter. The CVFD element provides wider fractional delay range compared to the FDS used in the existing FDS based filter, and hence, the IFDS based filter overcomes the lower limit on fc of the FDS based filter. Due to inherent limitations of the FDS, the FDS based filter has an upper limit on fc of the FDS based filter. In the IFDS based filter, we use the CVFD element to vary fc of the filter below this limit and then use interpolation technique to obtain variable multiband response. This multiband response of the interpolated filter is used along with its complementary response to obtain lowpass responses with fc above the upper limit on fc of FDS based filter. Simulation results show that the magnitude and phase responses of the proposed IFDS based filter are not impaired by the use of FDS. No degradation is observed in the passband or the stopband of the IFDS based filter compared to that of the prototype filter. The proposed reconfigurable filter design technique can be easily extended to design reconfigurable filter banks with variable number of subbands and fine control over the subband bandwidth.
THE EFFECTS OF MEMORY LOAD IN VISUAL SEARCH ARE MODULATED BY SIMULARITY BETWEEN THE MATIRIALS INVOLVED

The effect of memory load in visual search has shown a high heterogeneity of results: while some researchers have found an impairment of performance under high memory load conditions (eg. Lavie & De Fockert, 2006), others have found no effect of memory load (eg. Woodman, Vogel & Luck, 2001), and even others have found an improvement of performance under high memory load conditions (Smilek, Enns, Eastwood, & Merikle, 2006). In the present research we propose that the relationship between the material retained in working memory (WM) in a secondary memory load task and the target and distractors involved in the visual search task might be a key factor for explaining the discrepancies in the results. We tested our hypothesis manipulating that relationship in four experiments. The results show that the relationships between the material in WM and the target and distractors in the attentional task may be a crucial factor in modulating the effect of memory load in visual search. If the items retained in WM are similar to those presented as targets in the attentional task, visual search performance improves under high memory load conditions. On the contrary, if the items retained in WM are similar to those employed as distractors in the visual search task, there is no modulation of memory load in visual search. Finally, we discuss the theoretical implications in the context of the endogenous and exogenous attentional processes involved in visual search.
Vibrotactile Force Perception – Absolute and Differential Thresholds and External Influences

Three experiments were carried out to determine absolute and differential thresholds for vibrotactile forces and external influences in the frequency range of 5 to 1,000 Hz at the tip of the index finger. Differential thresholds were obtained for reference stimuli of 0.5, 0.25 N, and near the individual threshold. Frequency, temperature, age, fingertip size, and contact force were investigated as parameters in a full-factorial design. Experiments were conducted with at least 27 subjects and a 1up-2down staircase procedure with 3IFC paradigm. We find absolute thresholds ranging from 1.7 to 19 mN with the lowest threshold at 320 Hz. Weber fractions from 18 to 41 dB are found near the absolute threshold. For larger references, they range from 4.9 to 23 dB. ANOVA finds frequency as significant medium effect for both absolute and differential thresholds. Results imply impact of age on the absolute threshold, but no effect of motor skill, temperature, fingertip size, and contact force. Differential thresholds are affected by frequency only, which is attributed to saturation effects of the Pacinian channel. Fingertip size and motor skill are not able to explain effects on thresholds and the interpersonal variance. Results of this work are intended as requirement source for the design of task-specific haptic interfaces.
Adolescent sexuality and sexual abuse : a swedish perspective

By using keratinocytes grown in a reconstructed skin model, the retinoid regulation of K2e and K4 expression was further investigated. Retinoids with various affinities for the nuclear receptors RAR and RXR were added to the culture and the keratin mRNA expression was monitored for several days. The most potent retinoids were found to be RARα agonists, the effects of which could be inhibited by addition of a panRAR antagonist.
A Longitudinal Study of Creative Personality in Women

The Mills Longitudinal Study, covering 30 years in the lives of approximately 100 women from the senior year of college to their early 50s, was begun as an investigation of creativity in women. After a presentation of the design of the study and its measures of creative potential and productivity, findings in several areas are reviewed. A central finding is that varied measures of creative potential assessed openness and unconventionality, manifested in both positive and negative ways, whereas creative productivity was associated with these traits along with strong creative motivation and resilience. Creative potential was actualized in some women in self-discovery through relationships rather than in careers. Creative traits showed impressive consistency over time, but the creative vitality of individuals fluctuated considerably with major changes in life situation. Creative productivity showed more relation to psychosocial development than did measures of creative potential.
Free-Breathing Contrast-Enhanced Multiphase MRI of the Liver Using a Combination of Compressed Sensing, Parallel Imaging, and Golden-Angle Radial Sampling

ObjectiveThe objectives of this study were to develop a new method for free-breathing contrast-enhanced multiphase liver magnetic resonance imaging (MRI) using a combination of compressed sensing, parallel imaging, and radial k-space sampling and to demonstrate the feasibility of this method by performing image quality comparison with breath-hold cartesian T1-weighted (conventional) postcontrast acquisitions in healthy participants. Materials and MethodsThis Health Insurance Portability and Accountability Act–compliant prospective study received approval from the institutional review board. Eight participants underwent 3 separate contrast-enhanced fat-saturated T1-weighted gradient-echo MRI examinations with matching imaging parameters: conventional breath-hold examination with cartesian k-space sampling volumetric interpolate breath hold examination (BH-VIBE) and free-breathing acquisitions with interleaved angle-bisection and continuous golden-angle radial sampling schemes. Interleaved angle-bisection and golden-angle data from each 100 consecutive spokes were reconstructed using a combination of compressed sensing and parallel imaging (interleaved-angle radial sparse parallel [IARASP] and golden-angle radial sparse parallel [GRASP]) to generate multiple postcontrast phases.Arterial- and venous-phase BH-VIBE, IARASP, and GRASP reconstructions were evaluated by 2 radiologists in a blinded fashion. The readers independently assessed quality of enhancement (QE), overall image quality (IQ), and other parameters of image quality on a 5-point scale, with the highest score indicating the most desirable examination. Mixed model analysis of variance was used to compare each measure of image quality. ResultsImages of BH-VIBE and GRASP had significantly higher QE and IQ values compared with IARASP for both phases (P < 0.05). The differences in QE between BH-VIBE and GRASP for the arterial and venous phases were not significant (P > 0.05). Although GRASP had lower IQ score compared with BH-VIBE for the arterial (3.9 vs 4.8; P < 0.0001) and venous (4.2 vs 4.8; P = 0.005) phases, GRASP received IQ scores of 3 or more in all participants, which was consistent with acceptable or better diagnostic image quality. ConclusionContrast-enhanced multiphase liver MRI of diagnostic quality can be performed during free breathing using a combination of compressed sensing, parallel imaging, and golden-angle radial sampling.
Conformational Stability and Disassembly of Norwalk Virus-like Particles

Greater than 99% of the Norwalk virus (NV) capsid consists of 180 copies of a single 58-kDa protein. Recombinantly expressed monomers self-assemble into virus-like particles (VLPs) with a well defined icosahedral structure. NV-VLPs are an appropriate vaccine antigen since the antigenic determinants of the parent virion are preserved. They also constitute very simple models to study the mechanisms of assembly and disassembly of viral capsids. This work examines the inherent stability of NV-VLPs over a range of pH and temperature values and provides detailed insight into structural perturbations that accompany disassembly. The NV-VLP structure was monitored using a variety of biophysical techniques including intrinsic and extrinsic fluorescence, high resolution second-derivative UV absorption spectroscopy, circular dichroism (CD), dynamic light scattering, differential scanning calorimetry, and direct observation employing transmission electron microscopy. The data demonstrate that NV-VLPs are highly stable over a pH range of 3-7 and up to 55 °C. At pH 8, however, reversible capsid dissociation was correlated with increased solvent exposure of tyrosine residues and subtle changes in secondary structure. Above 60 °C NV-VLPs undergo distinct phase transitions arising from secondary-, tertiary-, and quaternary-level protein structural perturbations. By combining the spectroscopic data employing a multidimensional eigenvector phase space approach, an empirical phase diagram for NV-VLP was constructed. This strategy of visualization provides a comprehensive description of the physical stability of NV-VLP over a broad range of pH and temperature. Complementary, differential scanning calorimetric analyses suggest that the two domains of VP1 unfold independently in a pH-dependent manner.
Does neighborhood matter? Assessing recent evidence

Abstract This article synthesizes findings from a wide range of empirical research into how neighborhoods affect families and children. It lays out a conceptual framework for understanding how neighborhoods may affect people at different life stages. It then identifies methodological challenges, summarizes past research findings, and suggests priorities for future work. Despite a growing body of evidence that neighborhood conditions play a role in shaping individual outcomes, serious methodological challenges remain that suggest some caution in interpreting this evidence. Moreover, no consensus emerges about which neighborhood characteristics affect which outcomes, or about what types of families may be most influenced by neighborhood conditions. Finally, existing studies provide little empirical evidence about the causal mechanisms through which neighborhood environment influences individual outcomes. To be useful to policy makers, future empirical research should tackle the critical question of how and .
Hybrid Hardware / Software Synergism

Maximizing the efficiency of computing systems (hardware and software) in terms of power and processing is of paramount importance in the current age of revolutionary realtime hand-held computing devices. The packaging of heterogeneous computing devices (CPUs, ASICs, FPGAs, and associated communication protocols) on a single chip has been employed to mitigate issues such as power consumption and heat dissipation, but has yet to yield commensurate increases in computation efficiency or decreases in the cost of the software development for systems designed to operate on those devices. Existing compilers are amazingly efficient at code optimization and are capable of allowing some parallel processing by spreading the execution across a given number of available CPUs. The current off-the-shelf compiler technology is not, however, capable of spreading the processing across multiple non-homogeneous computing devices to provide the most efficient execution of the code for the given set of heterogeneous processing units. This is precisely the goal of our current Hybrid Computing (Hy-C) Compiler Project at the University of North Texas. Given a machine description file and source code, our Hy-C compiler is designed to partition the generated code to the specific types of computing devices that will provide the most efficient execution. Efficiency is measured in comparison to a set of constraints (power, throughput, heat, etc.) provided by the user. Thus, the goal of our compiler research will be to provide a novel capability of maximizing the execution potential of given software across a wide range of available processing components that can be combined on a single system on a chip.
