Knowledge, Experience, and Anxieties of Young Classical Singers in Training

Summary Objective/Hypothesis Young classical singers in training have a wide variety of knowledge about the anatomy and physiology of the voice and vocal pathology and harbor anxiety about treatment of vocal fold disorders. This study aimed to examine differences in knowledge, experience, and anxiety across levels of training at elite conservatories and young artist programs in the United States. Study Design Prospective cohort questionnaire. Methods Undergraduate (50), master's (35), and doctoral/young artist (25) singers (n = 110) were given an 80-point questionnaire assessing experience with vocal pathology, otolaryngologists, speech pathologists, and participation in choir or teaching. Participants were asked questions to test their medical knowledge in vocal anatomy, physiology, and care. They were also asked questions about their anxiety about medical visits and vocal pathology and about their habits in the care of their own voices. Results There was no statistically significant difference in test scores for vocal knowledge across the three levels of training ( P = 0.47). Mean scores were just above 50% with standard deviations around 12–13 points. The lowest score was 26% and the highest score was 84%. Doctoral/young artist-level participants were more anxious regarding general office visits to an otolaryngologist compared with undergraduate and master's level participants. There were no other significant differences by level of training regarding anxiety about vocal pathology, scope examinations, or visits to a speech pathologist. There were no significant differences in self-reported levels of knowledge. All groups of young singers expressed marked interest in expanding their knowledge of anatomy and physiology, speech pathology, care of the vocal mechanism, and vocal disorders. Conclusions More advanced singers do not have significantly greater knowledge of vocal form and function and are more anxious about visits to otolaryngologists and vocal pathology; a clear majority of singers indicate interest in knowing more. There is thus ample opportunity for innovation in the development of medical curricula in the instruction of young singers and clear interest in more knowledge on their part.
Phased-Array and Radar Breakthroughs

Many think that radar is a mature field, nothing new to happen, it having been around a long time. Nothing can be further from the truth. When I entered the field in the '50s I thought the same thing. The MIT Radiation Lab. Series 28 book volume set summarizing the highly classified World War II work on radar was just published and provided the definitive coverage and there was to be nothing more to learn. How wrong I was. Since then many amazing new developments have taken place. Things are moving even faster now. We live in exciting times. Phased array radars and radars have seen in recent years breakthroughs that lead to capabilities not possible only a few years ago. This is exemplified by the development of GaAs integrated microwave circuits called monolithic microwave integrated circuits (MMIC) which makes it possible to build active electronically scanned arrays (AESAs) having lighter weight, smaller volume, higher reliability and lower cost. MMIC allows the construction of AESAs for applications not feasible before. This integration has reached the point where it is possible to now build a low cost 35 GHz phased array for a missile seeker costing $40/element (total cost of array including all electronics divided by number of elements). The advances provided by Moore's Law has now made it is feasible to do digital beam forming with all its numerous advantages. One advantage of digital beamforming is the ability to lower the search power and occupancy by up to a factor of two. Another advantage is that it makes it possible to achieve the performance of a fully adaptive array without having to do a large matrix inversion, i.e., it makes adaptive-adaptive array processing or equivalently principal decomposition feasible. Also covered will be: the potential for GaN and SiC chips which have the capability of a factor of ten higher peak power than GaAs chips; arrays with instantaneous bandwidths of up to 33:1; SiGe low cost T/R modules; low cost MEMS arrays; metamaterials which provide negative refractivity possibly allowing focusing beyond the diffraction limit; a real radar application for Multiple-Input Multiple-Output (MIMO) as opposed to fantasy has been demonstrated by Lincoln Laboratory MIT which allows the coherent combining of two radars to achieve a 9 dB increase in sensitivity; the ability to build microwave tubes that are smaller, more power efficient, lighter, require lower voltages and have lower cost.

Ecological Synergies in Two Groups of Zoo Chimpanzees: Divergent Patterns of Time Use

This study investigated how two groups of zoo chimpanzees, one that lived in a small and mostly barren physical habitat yet had a successful social history and the other that lived in a larger and more enriched physical habitat yet had a turbulent social history, invested time occupationally. Different ecological synergies were found to emerge from these respective conditions and to influence time use in highly particularistic ways. As related to considerations of adaptedness, the limits of enriched physical environs when coupled with a dearth of social facilitation were revealed, as were the limits of social facilitation within impoverished physical spaces. Findings suggest that occupational therapists' expertise in activity analysis could be enlarged to encompass analysis of naturally socially embedded ways of doing things across multiple contexts. To advance the ethic of occupational justice, functional assessments of individuals could also be expanded into functional assessments of the occupational aliveness of proximate life environments.
Resting brain activity in disorders of consciousness: a systematic review and meta-analysis.

Objective: To quantitatively synthesize results from neuroimaging studies that evaluated patterns of resting functional activity in patients with disorders of consciousness (DOC). Methods: We performed a systematic review and coordinate-based meta-analysis of studies published up to May 2014. Studies were included if they compared resting-state functional neuroimaging data acquired in patients with DOC (coma, minimally conscious state, emergence from minimally conscious state, or vegetative state) with a group of healthy controls. Coordinate-based meta-analysis was performed in studies that included voxel-based comparisons at the whole-brain level and if analysis was accomplished with data-driven approaches. Results: A total of 36 studies (687 patients, 637 healthy controls) were included in the systematic review. Reported DOC were vegetative state (43.2%), coma (23.4%), minimally conscious state (22.8%), and emergence from minimally conscious state (1.6%); the most common etiologies of DOC were traumatic brain injury (37.7%) and anoxic brain injury (36.9%). Functional neuroimaging was accomplished using fMRI (16 studies), PET (15 studies), SPECT (4 studies), and both PET and SPECT in one study. Meta-analysis in 13 studies (272 patients, 259 healthy controls) revealed consistently reduced activity in patients with DOC in bilateral medial dorsal nucleus of the thalamus, left cingulate, posterior cingulate, precuneus, and middle frontal and medial temporal gyri. Conclusions: In patients with DOC evaluated in the resting state, functional neuroimaging indicates markedly reduced activity within midline cortical and subcortical sites, anatomical structures that have been linked to the default-mode network. Studies are needed to determine the relation between activation (and coherence) within these structures and the emergence of conscious awareness.
Response of Venezuelan Output to Monetary Policy, Deficit Spending, and Currency Depreciation: A Var Model

This study applies the VAR model to find possible responses of real GDP to selected macroeconomic variables in Venezuela. Based on an annual sample during 1961-2001, the author finds that the real GDP responds positively to a shock to real M2 , goverment deficit spending, exchange rate depreciation, and the lagged output and negatively to a shock to the inflation rate during some of the time periods. Except for the lagged output, government deficit spending and the inflation rate are the most influential variable in the first year, and real M2 and the real exchange rate are more influential and have longer - term after the first year.
A selective impairment of motion perception following lesions of the middle temporal visual area (MT)

Physiological experiments indicate that the middle temporal visual area (MT) of primates plays a prominent role in the cortical analysis of visual motion. We investigated the role of MT in visual perception by examining the effect of chemical lesions of MT on psychophysical thresholds. We trained rhesus monkeys on psychophysical tasks that enabled us to assess their sensitivity to motion and to contrast. For motion psychophysics, we employed a dynamic random dot display that permitted us to vary the intensity of a motion signal in the midst of masking motion noise. We measured the threshold intensity for which the monkey could successfully complete a direction discrimination. In the contrast task, we measured the threshold contrast for which the monkeys could successfully discriminate the orientation of stationary gratings. Injections of ibotenic acid into MT caused striking elevations in motion thresholds, but had little or no effect on contrast thresholds. The results indicate that neural activity in MT contributes selectively to the perception of motion.
The Pathoplastic Relationship Between Interpersonal Problems and Fear of Failure

This study advances the understanding of fear of failure (FF), a dispositional avoidance-oriented achievement motive, by employing interpersonal classification techniques to groups of individuals who fear failure in order to examine the pathoplastic relations between FF and interpersonal problems. Shame-based FF is thought to be related to the self-regulation strategies of appeasement and aggression, and these strategies are hypothesized to be associated with the interpersonal problems of Nonassertiveness and Vindictiveness, respectively. Using 2 independent samples (ns=60 and 38) reporting high FF, interpersonal profiles were examined for the groups in their entirety and for cluster solutions within the larger samples. Results demonstrated that individuals high in FF exhibited 1 of 2 prototypical interpersonal profiles associated with Domineering/Vindictive or Nonassertive/Exploitable problems that correspond with the hypothesized aggression and appeasement regulation strategies. Consistent with the concept of pathoplasticity, these differences were not better accounted for by demographic, affective, motivational, personality, or attachment style characteristics of the samples.
RNA-Seq of human neurons derived from iPS cells reveals candidate long non-coding RNAs involved in neurogenesis and neuropsychiatric disorders

Genome-wide expression analysis using next generation sequencing (RNA-Seq) provides an opportunity for in-depth molecular profiling of fundamental biological processes, such as cellular differentiation and malignant transformation. Differentiating human neurons derived from induced pluripotent stem cells (iPSCs) provide an ideal system for RNA-Seq since defective neurogenesis caused by abnormalities in transcription factors, DNA methylation, and chromatin modifiers lie at the heart of some neuropsychiatric disorders. As a preliminary step towards applying next generation sequencing using neurons derived from patient-specific iPSCs, we have carried out an RNA-Seq analysis on control human neurons. Dramatic changes in the expression of coding genes, long non-coding RNAs (lncRNAs), pseudogenes, and splice isoforms were seen during the transition from pluripotent stem cells to early differentiating neurons. A number of genes that undergo radical changes in expression during this transition include candidates for schizophrenia (SZ), bipolar disorder (BD) and autism spectrum disorders (ASD) that function as transcription factors and chromatin modifiers, such as POU3F2 and ZNF804A, and genes coding for cell adhesion proteins implicated in these conditions including NRXN1 and NLGN1. In addition, a number of novel lncRNAs were found to undergo dramatic changes in expression, one of which is HOTAIRM1, a regulator of several HOXA genes during myelopoiesis. The increase we observed in differentiating neurons suggests a role in neurogenesis as well. Finally, several lncRNAs that map near SNPs associated with SZ in genome wide association studies also increase during neuronal differentiation, suggesting that these novel transcripts may be abnormally regulated in a subgroup of patients.
AIDS: risk of HIV infection to health care workers.

Dr. Jaffe presented an update on the risk of HIV infection to health care workers. He noted that information has come from three sources: 1) analysis of national AIDS surveillance data: 2) prospective studies of injuries and exposures of health care workers: and 3) anecdotal reports. The national AIDS surveillance data indicate that 5% of reported AIDS cases occur in health care workers; health care workers represent 5.7% of the US workforce. By itself, this would suggest that employment as a health care worker is not associated with a disproportionately large risk of AIDS. The health care workers with AIDS have an age and sex distribution that is similar to that of all AIDS patients; the health care workers with AIDS are more likely to be white, however. The health care workers with AIDS are more likely to he homosexual/bisexual men (73%) than are all AIDS patients (62%); conversely, they are less likely to admit to intravenous drug use.
A study of the learning of three-layer back-propagation pattern recognizers for statistical quality control charts

Summary form only given, as follows. Back-propagation pattern recognizers are developed to identify unnatural patterns exhibited on statistical quality control charts. These unnatural patterns can provide valuable information for real-time process control. The selection of training patterns is iteratively determined by a training refinement procedure. The learning speed of these recognizers is studied by the rate of convergence and the actual training time. Nine different network configurations were investigated. The actual training time was characterized by known parameters such as the number of processing elements in each layer of the network, and was illustrated by computer processor time as well. The results indicate that the training time is on a manageable and affordable scale for problems of such magnitude. >
Redemptive suffering: Christ's alone

In recent years feminists and others have taken issue with traditional understandings of the atonement. Part of their criticism has been the assertion that to glorify Christ's suffering entails glorifying all suffering, a connection that potentially leads to abusive behaviour. Suffering, they claim, is not redemptive – ever. In this article I argue that, based on the biblical text, at least one instance of suffering, the suffering of Christ, is redemptive. In addition, I argue that redemptive suffering is unique to Christ. Human suffering is not redemptive and should not be spoken of in those terms.
COMPARATIVE IN VITRO CYTOTOXICITY OF ETHYL ACRYLATE AND TRIPROPYLENE GLYCOL DIACRYLATE TO NORMAL HUMAN SKIN AND LUNG CELLS

The potential for occupational exposure to the esters of acrylic acid (acrylates) is considerable, and, thus, requires a greater understanding of the their toxicity. Confluent (70-90%) cultures of normal human epidermal keratinocytes (NHEK), dermal fibroblasts (NHDF). or bronchial epithelium (NHBE) were exposed to the monofunctional ethyl acrylate (EA), the multifunctional tripropylene glycol diacrylate (TPGDA), or TPGDA monomer in a radiation curable lacquer (Lacquer A) at equimolar dosages in order to determine human in vitro cytotoxicity. Viability of the cells after 2-24-h exposure to the representative monofunctional or multifunctional acrylate or solvent control was used to calculate an index of acute cytotoxicity (50% inhibitory dose; ID50) and to determine the shape of the dose-response curves. TPGDA, Lacquer A, and EA were equally cytotoxic (ID50 is approximately equal to 0.1 micromol/cm2) to NHEK at equimolar doses. TPGDA or Lacquer A were more cytotoxic (is approximately equal to 100X) to NHDF or NHBE than EA. Sequential exposure of UV(A) and TPGDA to NHEK indicate the potential for a synergistic cytotoxic response. These findings are consistent with observed decreases in free sulfhydryl groups (e.g., glutathione or cysteine) that parallel the dose-response-related decreases in viability. logether, these data suggest possible differences in toxicity between the monofunctional EA and multifunctional TPGDA to NHEK, NHDF. or NHBE, possibly due to the difference in the number of functional acrylate groups and/or physicochemical differences (e.g., vapor pressure) between the acrylates investigated.
Encouraging Reading of Diverse Political Viewpoints with a Browser Widget

The Internet gives individuals more choice in political news and information sources and more tools to filter out disagreeable information. Citing the preference described by selective exposure theory — people prefer information that supports their beliefs and avoid counter-attitudinal information — observers warn that people may use these tools to access only agreeable information and thus live in ideological echo chambers. We report on a field deployment of a browser extension that showed users feedback about the political lean of their weekly and all time reading behaviors. Compared to a control group, showing feedback led to a modest move toward balanced exposure, corresponding to 1-2 visits per week to ideologically opposing sites or 5-10 additional visits per week to centrist sites.
Abstract 63: ACE2 Deficiency Reduces Insulin Content of Isolated Pancreatic Islets and Plasma Insulin Concentrations Post-Glucose Challenge in Obese C57BL/6 Mice

Objective: Diet-induced obesity promotes type 2 diabetes (T2D). Drugs that inhibit the renin-angiotensin system (RAS) have been demonstrated in clinical trials to decrease the onset of T2D. Angiotensin converting enzyme 2 (ACE2) negatively regulates the RAS by catabolizing angiotensin II (AngII). Preliminary data indicate that ACE2 deficient mice display impairments in glucose homeostasis at 8 weeks of age. We tested the hypothesis that ACE2 deficiency promotes the development of glucose intolerance and β-cell dysfunction in mice with diet-induced obesity. Methods and Results: Male Ace2 +/y or -/y mice were fed a low fat (LF, 10% kcal as fat) or high fat (HF, 60% kcal as fat) diet for 5 or 17 weeks. After 5 weeks, plasma insulin concentrations (0, 30 min) following a glucose challenge were significantly greater in HF versus ( vs) LF-fed mice. However, glucose-stimulated increases in plasma insulin concentrations were decreased in HF-fed ACE2 deficient mice compared to controls (2.96 ± 0.18 vs 4.44 ± 0.40 ng/ul, respectively; P Ace2 -/y compared to +/y mice (1.76 ± 0.17 vs 2.54 ± 0.18 insulin/18S ratio; P vs 13.90 ± 1.10 ng/ul; P vs 3.09 ± 0.98 ng/ul; P vs 0.169 ± 0.01, ACE2/18S ratio; P vs 0.9 ± 0.26, fold change over basal; P Conclusions: These results demonstrate that ACE2 deficiency promotes the development of T2D by regulating islet insulin content. Moreover, diet-induced obesity reduces islet ACE2 gene expression with augmented AngII-induced impairment of insulin secretion.
Overexpression of BDNF in the ventral tegmental area enhances binge cocaine self-administration in rats exposed to repeated social defeat.

Stress is a major risk factor for substance abuse. Intermittent social defeat stress increases drug self-administration (SA) and elevates brain-derived neurotrophic factor (BDNF) expression in the ventral tegmental area (VTA) in rats. Intra-VTA BDNF overexpression enhances social defeat stress-induced cross-sensitization to psychostimulants and induces nucleus accumbens (NAc) ΔFosB expression. Therefore, increased VTA BDNF may mimic or augment the development of drug abuse-related behavior following social stress. To test this hypothesis, adeno-associated virus (AAV) was infused into the VTA to overexpress either GFP alone (control) or GFP + BDNF. Rats were then either handled or exposed to intermittent social defeat stress before beginning cocaine SA training. The SA acquisition and maintenance phases were followed by testing on a progressive ratio (PR) schedule of cocaine reinforcement, and then during a 12-h access "binge" cocaine SA session. BDNF and ΔFosB were quantified postmortem in regions of the mesocorticolimbic circuitry using immunohistochemistry. Social defeat stress increased cocaine intake on a PR schedule, regardless of virus treatment. While stress alone increased intake during the 12-h binge session, socially-defeated rats that received VTA BDNF overexpression exhibited even greater cocaine intake compared to the GFP-stressed group. However, VTA BDNF overexpression alone did not alter binge intake. BDNF expression in the VTA was also positively correlated with total cocaine intake during binge session. VTA BDNF overexpression increased ΔFosB expression in the NAc, but not in the dorsal striatum. Here we demonstrate that VTA BDNF overexpression increases long-access cocaine intake, but only under stressful conditions. Therefore, enhanced VTA-BDNF expression may be a facilitator for stress-induced increases in drug abuse-related behavior specifically under conditions that capture compulsive-like drug intake.
Abstract 536: Resiniferatoxin-induced Disorders in Glucose Homeostasis and Hypertension: Role of Trpv1-positive Sensory Nerves

Resiniferatoxin (RTX), an ultrapotent agonist of the transient receptor potential vanilloid 1 (TRPV1) channels, has been used to relieve pain in humans in clinical trials that are ongoing, completed, or terminated due to its unwanted side effects that have not been well understood. We test the hypothesis that RTX causes disorders in glucose homeostasis, renal functional and structural impairment, and hypertension via insulin receptor-mediated increases in sympathetic nerve activity. Male Wistar rats were injected with RTX (0.2 mg/kg, i.p.) or vehicle. Pancreatic and renal TRPV1 levels were decreased 4 weeks after RTX treatment, confirming effective and lasting treatment of RTX (p
The mental number-line spreads by gestural contagion.

Mathematical expertise builds on a foundation of space, especially the ability to map exact numbers to linear space. This “mental number-line” is known to vary cross-culturally, but there is debate about the mechanisms responsible for its cultural elaboration. We investigated the role of co-speech gesture, a ubiquitous cultural activity, in stabilizing and entrenching the mental number-line within a community. Imitating culture-specific gestures systematically shaped gesturers’ mental number-line. Moreover, gestures were used spontaneously to infer speakers’ spatial understanding of number, and merely observing these gestures was sufficient to shape the observer’s own mental number-line. These findings establish co-speech gesture as one mechanism for propagating and perpetuating the number-line.

A survey of patients' understanding and expectations of persistent postsurgical pain in a preoperative testing center

Abstract Study Objective Acute postoperative pain may transition to persistent/chronic pain in up to 50% or more of patients after certain surgeries. Despite this concern, it is unclear that patients' preprocedure understanding and expectations are aligned with these potential outcomes. This study was designed to evaluate the extent of this alignment and the potential impact on the quality of risk/benefit discussions before procedures. Design Prospective survey. Setting A large, tertiary care preoperative assessment clinic. Patients A total of 1481 adult patients. Interventions Survey administration. Measurements The survey items evaluated patients' expectations of postoperative pain and how familiar patients were with the risk of persistent postsurgical pain based on their specific characteristics and procedure type. Main Results The overwhelming majority (80%) of patients were unaware of the risk of persistent postsurgical pain. Given the choice, most patients (65%) wanted to be informed of their risk, and 25% stated that it might even affect their decision to proceed with surgery. Conclusions There is great need for health care providers to discuss the significant risk of persistent postsurgical pain with patients in the preoperative setting. Patients need to be armed with realistic data to ensure high-quality discussions of risk/benefit, align expectations with outcomes, and potentially identify high-risk groups in which preoperative intervention can reduce the likelihood or severity of persistent postoperative pain syndromes.
“When Father Is Restored, Family Can Be Reestablished”: Father School

Chapter 2 examines the ways in which Father School redefines hegemonic masculinity by deprioritizing men’s financial responsibility that is one of the core elements of hegemonic masculinity. Started in a late-achiever/wellbeing Right type of megachurch, Father School has grown into a transnational evangelical men’s manhood and fatherhood restoration movement, calling for the reestablishment of men’s authority as the family head. By adjusting to the societal changes and ethos that demand less authoritarian and less violent manhood, Father School has managed to reinforce patriarchy as “acceptable” by reframing it to be “benevolent.” The promotion of such patriarchy only strengthens heteropatriarchal family structure as “natural” and “normal.” It also redomesticates women by validating their identity as a wife and mother to be women’s most valuable positions.
Mapping magnetoelastic response of terfenol-D ring structure

The magneto-elastic response of a Terfenol-D (Tb.3Dy.7Fe1.92) ring has been experimentally investigated and analyzed. Ring structures give rise to complex behavior based on the interaction of the magnetic field with the material, which is further compounded with anisotropies associated with mechanical and magnetic properties. Discrete strain measurements were used to construct magnetostriction maps, which are used to elucidate the non-uniformity of the strain distribution due to geometrical factors and magnetic field interactions, namely, magnetic shielding and stable onion state in the ring structure.
Thoughts on the Policy Aspects of Migration and Urban Employment Growth

Long-term trends in the regional distribution of population, labor force, and employment are the results of powerful economic and social forces. Many of these same forces also reshape the intraurban distribution of economic activity. Technological change, in combination with rising incomes and desires for different lifestyles, has facilitated and encouraged the Westward and Southward movements of population and employment in addition to the movements of population and employment to the suburbs of the nation's major metropolitan areas. The chapter discusses the rationale for public intervention, manpower training programs, and the market imperfections that prevent local and national labor markets from functioning more efficiently. The chapter focuses on a number of factors that have encouraged differentially sizeable numbers of families and individuals to relocate.
Reuse-Centric K-Means Configuration

K-means configuration is a time-consuming process due to the iterative nature of k-means. This paper proposes reuse-centric k-means configuration to accelerate k-means configuration. It is based on the observation that the explorations of different configurations share lots of common or similar computations. Effectively reusing the computations from prior trials of different configurations could largely shorten the configuration time. The paper presents a set of novel techniques to materialize the idea, including reuse-based filtering, center reuse, and a two-phase design to capitalize on the reuse opportunities on three levels: validation, k, and feature sets. Experiments show that our approach can accelerate some common configuration tuning methods by 5-9X.
Proximate composition, lipid utilization and validation of a non-lethal method to determine lipid content in migrating American shad Alosa sapidissima.

Lipid content forms the most important energy reserve in anadromous fish and can limit survival, migration and reproductive success. A fat meter was evaluated and compared with a traditional extractive method of measuring available lipid for migrating American shad Alosa sapidissima in the Connecticut River, U.S.A. The fat meter gives rapid (<10 s) and non-lethal lipid measurements, whereas traditional methods require lethal sampling that is both time consuming and expensive. The fat-meter readings had a strong relationship to traditional lipid extractions for 60 fish, 30 whole body (R2 = 0·72) and 30 fillet only (R2 = 0·81). Additional validation showed that fat-meter readings captured the gradual decrease of lipid in individual fish over time, were not affected by removal of gonads or scales and were stable for fish exposed to water or air for 24 h after death. These experiments indicate that the fat meter can be used as a reliable tool for future A. sapidissima energetic studies, allowing for larger sample sizes and non-lethal sampling.
Multi-point vibration measurement and mode magnification of civil structures using video-based motion processing

Abstract Image-based vibration measurement has gained increased attentions in civil and construction communities. A recent video-based motion magnification method was developed to measure and visualize small structure motions. This new approach presents a potential for low-cost vibration measurement and mode shape identification. Pilot studies using this approach on simple rigid body structures were reported. Its validity on complex outdoor structures has not been investigated. In this study, a non-contact video-based approach for multi-point vibration measurement and mode magnification is introduced. The proposed approach can output a full-field vibration map that increases the efficiency of the current structural health monitoring (SHM) practice. The multi-point approach is developed based on the local phases which also fill the gap of the existing intensity-based multi-point vibration measurement. As an extension of the phase-based motion magnification, the multi-point measurement result is then integrated with the maximum likelihood estimation (MLE) to estimate the magnified frequency bands at each identified structure mode for operational deflection shape (ODS) visualization. This proposed method was tested in both indoor and outdoor environments for validation. The results show that using the developed method, mode frequencies and mode shapes of multiple points in complex structures can be simultaneously measured. And vibrations in each mode can be visualized separately after magnification.
Designing Interfaces for Faster Information Processing: Examination of the Effectiveness of Using Multiple Information Cues

One of the problems studied in human-computer interaction (HCI) research is the design of interfaces that improve user information selection and processing performance. Based on prior research findings this study proposes that information selection can be improved by using multiple, supplementary cues to encode information in interface design. The research is motivated by cue-summation theory. Color and information location are proposed as relevant, supplementary cues that can improve processing performance by enhancing the reliance on a fast and automatic associative processing. Most prior studies examining the benefits of color have not controlled for information location. Our study describes a laboratory experiment in which both color and information location are employed as supplementary cues in a customer account management application. The results suggest that color and location cues significantly improve information selection and processing speed, along with user satisfaction, with the best results obtained when both cues are used.
Regional Therapy of Hepatic Metastases: Prognostic Factors

The liver is a common first site of metastatic involvement of colorectal adenocarcinoma. Progressive hepatic destruction and eventual failure to control metastatic disease are responsible for 25%–33% of the 20 000 deaths each year in the United States from this tumor [6, 12]. Clinical trials utilizing systemic 5-fluorouracil (5-FU) for colorectal metastases began at the University of Wisconsin shortly after the discovery of this drug in 1957 [11]. Response rates of up to 20% were observed following systemic administration; however, systemic 5-FU administration was limited by toxicity, including mucositis, diarrhea, and myelosuppression. In addition, progressive hepatic disease continued to be a major cause of clinical failure [1,4].
Philosophy of Medicine and Medical Ethics: A Phenomenological Perspective

The phenomenological orientation I have taken differs from the usual derivations of the ethics of medicine from the applications of existing moral philosophies to medical practice. It departs from the many current alternative ethical theories like narrative, casuistry, caring and principlism. Each of these, however, grasps some aspect of the life-world of doctor and patient. None is by itself sufficient as a philosophy or ethic of the clinical encounter. By bracketing these theories at the outset, the phenomenological orientation offers an alternative which may come closer to the thing in itself; namely, what medicine is as a human experience and a moral enterprise.
Coal-Fire Microarthropods From the Centralia, Pennsylvania and Healy, Alaska Mine Fires

Abstract Gas vents emitting water vapor and CO2 at the Centralia, Pennsylvania and Healy, Alaska coal-mine fires provided auspicious environments for the growth of vegetation adjacent to and near these vents. The vegetation created a living habitat for springtails, mites, beetles, beetle larvae, thrips, and aphids. Coal-fire gas exhaled at the surface and the associated elevated temperatures likely created an oasis for these microarthropods by warding off larger predators that would consume the vegetation. The microarthropods exhibit a tolerance of unknown duration to compounds in the gas, including toluene (C7H8), benzene (C6H6), and CO, known to be toxic to humans and other animals. The fauna at the mine fires may be opportunists because of less competition from other organisms that are more sensitive to the gas, combustion-related temperatures, or both. Only springtails occurred adjacent to the vents, the highest-temperature sampling locations. This suggests that of all the microarthropods identified, springtails were the most tolerant of the gas and higher temperatures at the vents. Springtails and mites both living near gas vents may have a higher tolerance than other microarthropods to the gas and ambient soil and vegetation temperatures due to combustion. Entomobryomorpha and Poduromorpha springtails and Oribatida mites were randomly distributed with increasing distance from a gas vent at Centralia, and the abundance of microarthropods increased with distance from this vent. Most Oribatida occurred at the furthest sampling location from the vent, where beetles also occurred. This is likely because more Oribatida were picked up and carried on the backs of beetles to the furthest sampling location than the beetles that migrated there. An eight-step procedure for collecting microarthropods at coal-mine fires will facilitate the acquisition and interpretation of the relationships between these fauna; coal-fire gas chemistry; and gas, soil, and vegetation temperatures at and near gas vents or other hot spots at coal fires.

Assessing the implementation of the National Archives and Records Service Act at Eduardo Mondlane University in Mozambique

Archival legislation is a crucial tool for the public sector to ensure the management, preservation and access of a country’s national documentary heritage. In Mozambique, archival legislation which has been enacted sets the scene for records appraisal and disposition, as well as classification schemes and retention schedules for administrative records of governmental bodies falling under the auspices of the National Archives and Records Services Act No. 36 of 2007 (NARSA). Despite this, the records management processes of many public entities in Mozambique have remained ineffective and inefficient. This article presents the data from a study conducted by Pereira (2017), which utilized the record life cycle concept as a framework to assess the state of implementation of the NARSA at Eduardo Mondlane University (EMU) in Mozambique. The study applied a quantitative research approach with triangulation of data collection tools, namely, questionnaire and document analysis. Data collected in the study revealed that EMU has established only one central records appraisal, destruction and transfer committee for its directorate units, which has not coped with the records management demands from other academic units such as faculties, schools and research centres. In most of the academic units, the records management staff were not involved in the training, records appraisal, destruction and transfer processes as required by legislation. Data analysis concludes that most EMU units do not comply with archival legislation, resulting in few prescriptions of the Act being implemented. The study recommends that the records management department at EMU should put in place the basic procedures of control for records management systems with the leadership taking a proactive role in strategic planning, budgeting and monitoring. Furthermore, it is recommended that another empirical study focusing on the assessment of implementation of the NARSA throughout the entire public sector in Mozambique should be undertaken.
Blast-induced tinnitus: Animal models

Blast-induced tinnitus is a prevalent problem among military personnel and veterans, as blast-related trauma damages the vulnerable microstructures within the cochlea, impacts auditory and non-auditory brain structures, and causes tinnitus and other disorders. Thus far, there is no effective treatment of blast-induced tinnitus due to an incomplete understanding of its underlying mechanisms, necessitating development of reliable animal models. This article focuses on recent animal studies using behavioral, electrophysiological, imaging, and pharmacological tools. The mechanisms underlying blast-induced tinnitus are largely similar to those underlying noise-induced tinnitus: increased spontaneous firing rates, bursting, and neurosynchrony, Mn++ accumulation, and elevated excitatory synaptic transmission. The differences mainly lie in the data variability and time course. Noise trauma-induced tinnitus mainly originates from direct peripheral deafferentation at the cochlea, and its etiology subsequently develops along the ascending auditory pathways. Blast trauma-induced tinnitus, on the other hand, results from simultaneous impact on both the peripheral and central auditory systems, and the resultant maladaptive neuroplasticity may also be related to the additional traumatic brain injury. Consequently, the neural correlates of blast-induced tinnitus have different time courses and less uniform manifestations of its neural correlates.

Internal Training Load Measures During a Competitive Season in Collegiate Women Lacrosse Athletes

Monitoring internal load provides useful and non-invasive markers of training stress and adaptation. However, the relationship between internal load measures across a competitive window remains inconclusive and limited. The purpose of this study was to report various internal load measures, as well as their relationship, across a season in Division I women lacrosse athletes (n = 20). Ultra-short natural logarithm of the root mean square of successive differences (lnRMSSD), salivary testosterone, cortisol, the testosterone:cortisol ratio, and self-reported measures of fatigue and recovery were collected weekly for 13 weeks. Means ± SD were calculated to provide descriptive values and a repeated measure analysis of variance (ANOVA) was used to analyze changes in testosterone, cortisol, testosterone:cortisol ratio (n = 8), and lnRMSSD (n = 8) over the course of the season. Pearson correlations assessed relationships between all internal load measures. No significant time effect was observed in testosterone (p = 0.059), cortisol (p = 0.544), testosterone:cortisol ratio (p = 0.120), or lnRMSSD (p = 0.062). lnRMSSD was correlated with testosterone (r = 0.265), cortisol (r = -0.232), testosterone:cortisol ratio (r = 0.345), and fatigue (r = -0.256) (p < 0.05). More research is needed to examine relationships among markers of internal stress across all phases of the training cycle. Routine monitoring may help practitioners optimize training programming to reduce injury, illness, and overtraining.

Dietary amino acid supplementation affects temporal expression of amino acid transporters and metabolic genes in selected and commercial strains of rainbow trout (Oncorhynchus mykiss).

Abstract Replacement of fishmeal as the major protein source in feeds is critical for continued growth and sustainability of the aquaculture industry. However, numerous studies have shown suboptimal fish growth performance and reduced protein retention efficiency when carnivorous fish species are fed low fishmeal-high plant protein feeds. A study was conducted using a commercial strain and a genetically improved strain of rainbow trout selected for improved performance when fed an all plant protein diet to identify physiological differences associated with growth performance in the selected trout strain. Fifty individuals per strain (average weight ~ 580 g) were force-fed a plant-protein blend with and without amino acid supplementation (lysine, methionine and threonine) at 0.5% body weight and sampled at intervals over 24 h. Samples from intestine and liver were analyzed for specific gene expression analysis related to amino acid transporters, digestive process control, protein degradation and amino acid metabolism. The results showed that expression levels of various intestinal amino acid transporters (SLC1A1, SLC7A9, SLC15A, SLC1A5 SLC6A19 and SLC36A1) were affected by strain, diet and time. Moreover, significant interactions were found regarding the temporal expression levels of cholecystokinin (CCK-L), Kruppel-like factor 15 (KLF15) and aspartate aminotransferase (GOT) transcripts in the examined tissues. The results provide evidence that improved growth and protein retention of the selected strain fed an all-plant protein diet is a result of nutritional adaptation and an overall change in physiological homeostatic control.
Sex-Based Analysis of Potential Inflammation-Related Protein Biomarkers in the Aqueous Humor of Patients With Diabetes Mellitus

Author(s): Haq, Zeeshan; Yang, Daphne; Psaras, Catherine; Stewart, Jay M | Abstract: PurposeTo investigate whether men have higher inflammatory protein biomarker concentrations in their aqueous humor (AH) compared with women in groups of patients with varying levels of diabetic disease.MethodsThis cross-sectional study included AH specimens from 59 adult patients comprised of three groups: no diabetes mellitus (DM), DM without diabetic retinopathy (DR), and DM with proliferative diabetic retinopathy (PDR). Protein biomarker concentration values were quantified using a commercial proximity extension assay-based technique.ResultsIntersex comparisons of concentration values for each protein biomarker revealed no discoveries in patients with no DM or with PDR. In contrast, 24 discoveries were detected in patients with DM without DR. The mean concentration value for all 24 protein biomarkers was higher in men compared with women. Of these 24 proteins, 12 demonstrated a significant association with sex on multivariate linear regression analysis. The β coefficient results demonstrated a positive association between male sex and concentration value for all 12 of these proteins.ConclusionsHigher AH concentration levels of several potential biomarkers, including chemokines, proteases, proteins involved in programmed cell death, and a T-cell surface protein, were detected in men with DM with no DR. These findings suggest that men may have a more inflammatory disease phenotype compared with women in this group of patients.Translational relevanceThe findings of this study help explain differences in epidemiologic patterns of diabetic retinopathy development between men and women.
