Selective Dipnetting of Largemouth Bass during Electrofishing

Abstract We electrofished 10 north-central Texas reservoirs from 1987 through 1990 by either dipnetting all electroshocked fish (intensive dipnetting) or selectively dipnetting only fish visually identified as largemouth bass Micropterus salmoides. We compared selected indices of population structure (proportional stock density, relative stock density, and young–adult ratio) and abundance (catch per unit effort) for largemouth bass derived from data obtained with these two dipnetting techniques. No significant differences (P > 0.17) were detected between intensive dipnetting and selective dipnetting for any of these indices of population structure, Similarly, neither the total number of largemouth bass collected per hour nor the number of small largemouth bass ( 0.31) between dipnetting techniques.
C57BL/6 mice fed high fat diets as models for diabetes-accelerated atherosclerosis

Non-insulin-dependent diabetes mellitus (NIDDM) is a major risk factor for the development of atherosclerosis in humans. The development of an animal model that displays accelerated atherosclerosis associated with NIDDM will aid in elucidating the mechanisms that associate these disorders. C57BL/6 mice may provide such a model system. This strain becomes obese, hyperglycemic and insulin resistant when fed a high fat diet (diabetogenic diet) and is susceptible to atherosclerotic lesion development when fed a separate high fat diet containing cholesterol and bile acids (atherogenic diet). This report tests whether a diet commonly used to induce atherosclerosis also provokes a diabetic phenotype and whether a diet used to induce diabetes provokes the development of aortic fatty streak lesions. Mice of strains C57BL/6, C3H/He, BALB/c and seven recombinant inbred (RI) strains were fed an atherogenic diet for 14 weeks and glucose parameters were measured. No correlation was observed between atherosclerosis susceptibility and fasting insulin or glucose levels, or glucose clearance following short-term insulin or glucose treatment. Analysis of the RI strains suggested that multiple genes control these glucose metabolic parameters. Feeding the diabetogenic diet for 14 weeks to C57BL/6 mice induced obesity and diabetes and 2-fold increases in plasma lipoprotein concentrations. Also, small aortic sinus lipid deposits were observed in 40% of the mice. Thus, analysis of the diabetogenic diet fed C57BL/6 mouse may provide an important tool for further studies of diabetes accelerated vascular disease.
Child Problem Recognition and Help-Seeking Intentions Among Black and White Parents

Parents play a central role in utilization of mental health services by their children. This study explored the relationship between parents' recognition of child mental health problems and their decisions to seek help. Participants included 251 parents (49% Black, 51% White; 49% fathers, 51% mothers) recruited from community settings. Parents ranged in age from 20 to 66 years old with at least one child between ages 2 and 21. Parents read three vignettes that described a child with an anxiety disorder, ADHD, and no clinically significant diagnosis. Parents completed measures of problem recognition, perception of need, willingness to seek help, and beliefs about causes of mental illness. Findings from Generalized Estimating Equations revealed that parents were more likely to report intentions to seek help when they recognized a problem (odds ratio [OR] = 41.35, p < .001), 95% confidence interval (CI) [14.81, 115.49]; when it was an externalizing problem (OR = 1.85, p < .05), 95% CI [1.14, 3.02]; and when parents were older (OR = 1.04, p < .05), 95% CI [1.01, 1.08]. Predictors of parental problem recognition included perceived need, prior experience with mental illness, and belief in trauma as a cause of mental illness. Predictors of help-seeking intentions included problem recognition, perceived need, externalizing problem type, and being female. Given the relationship between parental problem recognition and willingness to seek help, findings suggest that efforts to address disparities in mental health utilization could focus on problem-specific, gender-sensitive, mutable factors such as helping parents value help-seeking for internalizing as well as externalizing problems.
Antenatal health care policy, services and clients in urban Papua New Guinea.

This article describes the nurse-operated antenatal clinic services in Port Moresby Papua New Guinea and reports the findings of a survey of 365 women attending the Port Moresby General Hospital antenatal clinic. Only 9% of the women surveyed attended the clinic in the 1st trimester of their pregnancy with the majority making their 1st visit toward the end of the 2nd trimester. There was a trend toward later 1st visits with higher parities. 74% of previous deliveries had been in a hospital. Low hemoglobin level (52% under 10 gm%) was the common risk factor noted in the sample. The number of attendees generally decreased with increasing distance between home and hospital. To explore the factors associated with clinic attendance a subsample of 48 women were interviewed in depth. Clinic attendance was found to be significantly associated with the experience of current or previous obstetrical problems. The need to discover problems obtain medication and gain knowledge were reasons cited for clinic attendance. Respondents indicated they selected the hospital clinic because they expected greater expertise or better services. Clinic attendance was in some cases adversely affected by personal embarrassment stemming from questions about marital status from staff. Approximately 75% of women in the sample came from heterogeneous suburban areas that lack the social support systems commonly provided by extended family groupings. It is suggested that nursing interventions based on comprehensive counseling as well as a caring approach can play a unique role in the professional support system for obstetric care. It is important for nurses who function in antenatal clinic settings serving clients of diverse ethnicity to be aware of the cultural beliefs and values that influence health care perceptions and practices. Although nurses perform the majority of antenatal care in Papua New Guinea their knowledge of high risk factors is weak. Use of a specialized antenatal clinic card as well as continuing education are recommended to sharpen nurses assessment skills and facilitate early detection of high risk clients.
On the sensitivity of radial basis interpolation to minimal data separation distance

Motivated by the problem of multivariate scattered data interpolation, much interest has centered on interpolation by functions of the form $$f(x) = \sum\limits_{j = 1}^N {a_j g(\parallel x - x_j \parallel ),x \in R^s }$$ whereg:R + →R is some prescribed function. For a wide range of functionsg, it is known that the interpolation matricesA=g(∥x i −x j ∥) i,j=1 N are invertible for given distinct data pointsx 1,x 2,...,x N. More recently, progress has been made in quantifying these interpolation methods, in the sense of estimating the (l 2) norms of the inverses of these interpolation matrices as well as their condition numbers. In particular, given a suitable functiong:R + →R, and data inR s having minimal separationq, there exists a functionh s:R + →R +, which depends only ong ands, and a constantC s , which depends only ons, such that the inverse of the associated interpolation matrixA satisfies the estimate ‖A −1‖≤C s h s (q). The present paper seeks “converse” results to the inequality given above. That is, given a suitable functiong, a spatial dimensions, and a parameterq>0 (which is usually assumed to be small), it is shown that there exists a data set inR s having minimal separationq, a constant\(\tilde C_s\) depending only ons, and a functionk s (q), such that the inverse of the interpolation matrixA associated with this data set satisfies\(\parallel A^{ - 1} \parallel \geqslant \tilde C_s k_s (q)\). In some cases, it is seen thath s(q)=k s (q), so the bounds are optimal up to constants. In certain others,k s (q) is less thanh s (q), but nevertheless exhibits a behavior comparable to that ofh s (q). That is, even in these cases, the bounds are close to being optimal.
Fisher information embedding for video indexing and retrieval

In this paper, we present a novel information embedding based approach for video indexing and retrieval. The high dimensionality for video sequences still poses a major challenge of video indexing and retrieval. Different from the traditional dimensionality reduction techniques such as Principal Component Analysis (PCA), we embed the video data into a low dimensional statistical manifold obtained by applying manifold learning techniques to the information geometry of video feature probability distributions (PDF). We estimate the PDF of the video features using histogram estimation and Gaussian mixture models (GMM), respectively. By calculating the similarities between the embedded trajectories, we demonstrate that the proposed approach outperforms traditional approaches to video indexing and retrieval with real world data.
In vitro and in vivo effects of vanadate on K+-dependent phosphatase activities from subcellular fractions of brain, kidney and liver

Inhibition of K+-dependent phosphatases by sodium orthovanadate was studied in the subcellular fractions of brain, kidney and liver from male Sprague-Dawley rats. The concentration required to produce an in vitro phosphatase inhibition of 50% ranged from a low of 0.2 microM in the kidney 900 X g fraction to a peak of 400 microM in the brain soluble fraction. The concentrations required to produce 50% inhibition occurred in the micromolar range for most fractions studied. Injection of sodium vanadate (i.p., 8 mg/kg) produced phosphatase inhibition in several of the fractions, but not as pronounced as the in vitro treatment. The results indicate that vanadate is a potent inhibitor of phosphatase activity in vitro, and may have similar potential in vivo.
Global energy scenarios and the potential role of fusion energy in the 21st century

Global energy usage is increasing at about 2% p.a. The expansion is related to population growth and to demand for economic growth and higher standards of living, despite some economies in energy use per unit GNP. A severalfold increase in global electricity demand by the middle of the 21st century seems inevitable, with the largest increment from large-population developing countries such as China and India. Currently, most electricity is provided by carbon-based fossil fuels, by hydroelectricity and by nuclear fission. Fusion, with its potential to provide electricity from large central power stations could help meet a significant part of this expanding demand. It will have to be broadly competitive with established generating methods. Current advances in fusion research indicate good prospects for technical demonstration of fusion electricity generation. Research and development of materials for fusion energy is needed now not only for demonstration plant, but also to enhance the estimates of the competitivity of fusion and to maximise its economic and environmental potential.
An improved method detects differential NGF and BDNF gene expression in response to depolarization in cultured hippocampal neurons

Differential regulation of individual neurotrophins by impulse activity potentially allows transformation of instantaneous signalling into diverse, long-lasting neural alterations. To define the temporal profiles of trophin gene expression we examined nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) mRNAs in dissociated cell cultures of rat hippocampus using an improved solution hybridization technique. Traditional methods lack the precision and sensitivity to detect small changes during brief intervals and the facility to process large sample numbers simultaneously. This improved method has now allowed us to better define the dynamics of depolarization-induced changes in expression of individual trophin genes. Using elevated K+ as a depolarizing stimulus, NGF mRNA increased 40% after 48 h. In contrast, BDNF message rose almost 4-fold within 3 h and attained a maximal 6-fold increase within 6 h. Similar increases in BDNF mRNA levels were exhibited following treatment of cultures with glutamate, an excitatory neurotransmitter. To document the sensitivity of BDNF mRNA to depolarizing conditions, we examined expression after K+ withdrawal. BDNF message began decreasing within one hour post-depolarization, and returned to basal levels after 6 h. Observations indicate that BDNF and NGF mRNAs are induced differentially in response to impulse activity; BDNF message is acutely responsive to ongoing changes, whereas NGF mRNA responds more slowly and sluggishly. The physiological implications of this differential regulation are discussed.
A new encoding method for integrated-interleaved codes

The integrated-interleaved coding scheme can be used to compensate the format inefficiency due to small block length or to save hardware cost in designing codes of very long block length. In this paper, we derive a new systematic encoding method for the integrated-interleaved coding scheme for both the special case where the second level has a single component codeword, and the general case where the second level may have multiple component codewords. The proposed method enjoys the great advantage of performing logical sum (possibly a weighted) once, whereas the state-of-the-art method in literature requires performing twice.
Dynamic Analysis of Structural Systems Using Component Modes

A method is developed for analyzing complex structural systems that can be divided into interconnected components. Displacements of the separate components are expressed in generalized coordinates that are defined by displacement modes. These are generated in three categories: rigid-body, "constraint," and "normal" modes. Rigid-body modes are convenient where displacements are denned in inertial space for dynamic analysis. "Constraint" modes are included to treat redundancies in the interconnection system. "Normal" modes define displacements relative to the connections. Generalized mass, stiffness, and damping matrices are determined for each component, as are generalized forces. The requirement of system continuity gives rise to equations of displacement compatibility at the connections. These serve as equations of constraint among the component coordinates and are used to construct a transformation relating component coordinates to system coordinates. This transformation is used to derive system properties and forces from component properties and forces. System equations of motion are formulated and solved to determine system response. Component responses are found using the transformation. Connection forces are computed from the component equations. Each component can then be isolated and treated separately.
Monte Carlo Simulations of Film Profile Evolution During Nonplanar CVD Processes

A Monte Carlo simulation approach has been developed to model transport and film profile evolution for rarefied gas flows during nonplanar CVD over trenches and contact holes. A systematic study of the effect of various parameters on the film conformality including intermolecular collisions, reactant sticking coefficient and feature geometry is reported.
Reduced fading for RFID tags with multiple antennas

Using new, analytic expressions for the envelope probability density function (PDF) of the M times L times N dyadic backscatter channel, this paper demonstrates that modulating backscatter using multiple RF tag antennas can reduce small-scale fading. Several practical design guidelines are presented to exploit this property of the channel and to increase the RF tag range and reliability without a change in the signaling scheme.
On Jamming in the Wideband Regime

We consider the problem of jamming in non-coherent wideband fading channels. While the problem is well understood for coherent channels, the results for the coherent case do not generalize in the non-coherent regime. We show that energy-limited jammers do not affect capacity in the wideband regime. We also propose a training based transmission scheme that is able to achieve the wideband limit in the presence of a jammer.
Web Service Security model Using CBD Architecture

A Web services is programmable application logic accessible using standard Internet protocols. Web services combine the best aspects of component based development and the Web. like components, Web services represent black-box functionality that can be reused without knowing about how the service is implemented. Unlike current component technologies, Web services are not accessed via object-model-specific protocol. In this paper, we suggest the architecture development modeling and the Web integration architecture to develop Web service-security that is embodied in supplier on service oriented architecture (SOA). We also describe the various possibilities with which the components may be integrated well with applications have been explored and well-exposed using Web services. This paper focuses on integrating component based architecture modeling and Web services to enable the development and usage of facade and backside components through the Web by dynamically creating Web services-security for the functionalities of the components.
Problems of diagnosis and legal causation in courtroom use of post-traumatic stress disorder

Serious problems with the diagnosis of Post-Traumatic Stress Disorder (PTSD) render it vulnerable to legal challenge and subject to abuse. Problems in legal causation are outlined and include the issues of prior susceptibility, identification of the stressor, symptom assessment, intervening factors, and criminal responsibility. Trial courts continue to question the admissibility of PTSD expert witness testimony. To ensure the continuing validity of PTSD, its use should be limited, and expert witness testimony increasingly supported by empirically based research data. Language: en

Measurement of multiple drugs in urine, water, and on surfaces using fluorescence covalent microbead immunosorbent assay.

There are a range of applications that require the measurement of multiple drugs such as urine analysis, drug determination in water, and screening for drug contamination on surfaces. Some of the procedures used such as enzyme-linked immunosorbent assay (ELISA) are simple but can only determine one drug at a time, and others such as GC-MS or LC-MS are complex, time-consuming, and expensive. In this study, fluorescence covalent microbead immunosorbent assay (FCMIA) was investigated as a simple method for the measurement of multiple drugs simultaneously in three matrices: diluted urine, water, and on surfaces. Five different drugs of abuse or their metabolites (methamphetamine, caffeine, benzoylecgonine (a metabolite of cocaine), tetrahydrocannabinol (THC), the active ingredient in marijuana, and oxycodone) were studied over the range 0–15 ng/ml. There was no measureable cross-reactivity among the drugs at the concentrations studied. Urine dilutions from 1/50 to 1/2.5 were studied and dilutions less than 1/...
Gender‐Related Differences in Modulation of Heart Rate in Patients with Congestive Heart Failure

Gender and HRV in Heart Failure Introduction. The prognosis of women with congestive heart failure (CHF) is better than that for men, but the mechanisms underlying the female survival advantage are not well understood. CHF is characterized by profound abnormalities in cardiac autonomic control that contribute to progressive circulatory failure and influence survival. Methods and Results. Time- and frequency-domain heart rate variability (HRV) indexes were obtained from 24-hour Holter recordings and compared to assess the role of gender in 131 men and 68 women with CHF (mean age 60 ± 13.6 years, range 21 to 87; New York Heart Association Functional Class III [66%] and IV [34%]). Gender-related differences in HRV were observed only in the subset of patients with nonischemic heart failure (55 men and 39 women). Among the time-domain indexes, the SD of the RR intervals (76 ± 5.3 msec vs 55.3 ± 3.2 msec, P 50 msec variation (4.0%± 1.0% vs 6.5%± 1.3%, P = 0.02), and the square root of mean squared differences of successive RR intervals (19.1 ± 3.3 vs 28.4 ± 3.8, P = 0.004) were higher in women. Among the frequency-domain indexes, the total power (7.5 ± 0.13 In-msec2 vs 8.3 ± 0.14 In-msec2, P = 0.0002), the ultralow-frequency power (7.2 ± 0.11 In-msec2 vs 8.0 ± 0.14 In-msec2, P < 0.0001), the low-frequency power (3.8 ± 0.25 In-msec2 vs 4.8 ± 0.28 In-msec2, P = 0.006), and the high-frequency power (3.8 ± 0.24 In-msec2, vs 4.6 ± 0.26 In-msec2, P = 0.003) were greater in women than in men. Conclusion. Women with nonischemic CHF have an attenuated sympathetic activation and parasympathetic withdrawal compared with men. Gender-based differences in autonomic responses in the setting of CHF may be related to the female survival advantage. (J Cardiovasc Electrophysiol, Vol. 11, pp. 1071-1077, October 2000)
Do Online Students Perform as Well as Lecture Students

This paper reports research on whether online delivery performs as well as traditional lecture delivery for a computer science course at North Carolina State University. The comparisons made are for two large sections of the course for which almost the only difference was that one section attended on-campus lectures and the other did not. Where significant differences in outcomes appear for students who completed the course, they favor the online students. However, online students who started the course were less likely to complete it.
FDG PET Imaging of Head and Neck Cancers

In initial staging of head and neck cancers, the addition of FDG PET to conventional imaging improves the accuracy for cervical nodal metastases. The sensitivity of FDG PET is, however, limited in nodes <1 cm and in completely necrotic nodes. In the posttherapy setting, PET scans obtained at least 10 weeks after radiotherapy have an excellent predictive value to rule out residual disease. Due to the limited positive predictive value of FDG PET after radiation therapy, a positive PET scan needs to be confirmed before management decisions are made.
Transforming Mozambique: The Politics of Privatization, 1975–2000

Transforming Mozambique: The Politics of Privatization, 1975–2000. By M. Anne Pitcher. New York: Cambridge University Press, 2002. 320p. $60.00. Mozambique provides a sharp contrast with transition in much of Eastern Europe, the former Soviet Union, and even Asia. A Marxist movement (Frelimo) took power in 1975, pledging to construct a socialist state. Only 15 years later, a new constitution made no reference to socialism. By 1994, Mozambique was a multiparty democracy and one of the World Bank's “model” market reformers. Yet Frelimo remains in power, presiding over the private economy it once denounced. Why and how did this happen?
Vascular Targeted Photodynamic Therapy for Localized Prostate Cancer

Survival for men diagnosed with prostate cancer directly depends on the stage and grade of the disease at diagnosis. Prostate cancer screening has greatly increased the ability to diagnose small and low-grade cancers that are amenable to cure. However, widespread prostate-specific antigen screening exposes many men with low-risk cancers to unnecessary complications associated with treatment for localized disease without any survival advantage. One challenge for urological surgeons is to develop effective treatment options for low-risk disease that are associated with fewer complications. Minimally invasive ablative treatments for localized prostate cancer are under development and may represent a preferred option for men with low-risk disease who want to balance the risks and benefits of treatment. Vascular targeted photodynamic therapy (VTP) is a novel technique that is being developed for treating prostate cancer. Recent advances in photodynamic therapy have led to the development of photosynthesizers that are retained by the vascular system, which provides the opportunity to selectively ablate the prostate with minimal collateral damage to other structures. The rapid clearance of these new agents negates the need to avoid exposure to sunlight for long periods. Presented herein are the rationale and preliminary data for VTP for localized prostate cancer.

Computational Model Provides Insight into the Distinct Responses of Neurons to Chemical and Topographical Cues

Neuronal cell polarization (i.e., establishment of an axon) and axon guidance are mediated and controlled by mechanical and chemical signals from the environment. Unfortunately, an integrated approach to study cell–substrate interactions in a unified framework incorporating structural and chemical effects of the substrate has been lacking. In this paper, we present a new model combining experimental and computational methods to better understand the distinct behavior of E18 hippocampal neurons in response to topographical vs. immobilized chemical cues. We present results from our coarse-grain physiological computational model that correctly describes previously observed phenomena and predicts behavior that was subsequently tested through new experiments. The model differentiates topographical from chemical cues via a difference in cue spacing in these two substrates. Using the feature size spacing for topographical cues and a minimum step size, governed by the physics of filopodia protrusion, for chemical cues, the model successfully mimics the trend observed in experimental polarization probability for four different topographical feature sizes and constant chemical cue spacing. Our results not only show good agreement with experiments, but also provide novel suggestions for development of substrates for finer control of neuronal cell polarization.
3D Structural Patterns in Scalable, Elastomeric Scaffolds Guide Engineered Tissue Architecture

Microfabricated elastomeric scaffolds with 3D structural patterns are created by semiautomated layer-by-layer assembly of planar polymer sheets with through-pores. The mesoscale interconnected pore architectures governed by the relative alignment of layers are shown to direct cell and muscle-like fiber orientation in both skeletal and cardiac muscle, enabling scale up of tissue constructs towards clinically relevant dimensions.
Comments on Howe: Toward a More Inclusive “Scientific Research in Education”:

In response to Howe (2009), the author argues that educational research needs multiple thoughtful perspectives. The author’s standpoint is that of a mixed methods research methodologist. Mixed methods research provides an antidualistic and syncretic philosophy and set of approaches or possibilities for merging insights from diverse perspectives; its working goal is to provide pragmatic, ethical solutions to local and societal problems. To achieve this goal, researchers should cease writing articles that construct straw figures (based on old literature), knock them down, and claim Truth. The author of the present article provides a new set of guidelines for an education science that includes a respectful and important place for all. The author also provides a working value theory that resolves some objectivist and subjectivist differences.
Privacy preserving two-party k-means clustering over vertically partitioned dataset

We propose a secure approximate comparison protocol and develop a practical privacy-preserving two-party k-means clustering algorithm over vertically partitioned dataset. Experiments with to real datasets show that the accuracy of clustering achieved with our privacy preserving protocol is similar to the standard (non-secure) kmeans function in MATLAB.

Apolipoprotein A-II: Still Second Fiddle in High-density Lipoprotein Metabolism?

Apolipoprotein (apo) A-II is the second most abundant protein on high-density lipoprotein (HDL), accounting for ≈20% of total HDL protein.1 Like apo A-I, the most abundant HDL protein, it contains a tandem array of amphipathic helices. It is considered an exchangeable apolipoprotein because it can dissociate from lipoproteins, although it has greater lipid affinity than apo A-I.1 Despite the relative abundance of apo A-II, its role in HDL metabolism has long been a mystery, particularly whether it is an antiatherogenic or a proatherogenic protein. Data from in vitro HDL functional studies,2,3 mouse transgenic models,4,5 and human epidemiological studies6,7 have all been conflicting, concerning its pathophysiological role. A patient with apo A-II deficiency has been described,8 but this patient was largely unaffected in terms of her lipoprotein profile and appeared to be free of cardiovascular disease (CVD), suggesting that the role of apo A-II may be redundant with the other exchangeable apolipoproteins, such as apo A-I. See accompanying article on page 224 In this issue of Arteriosclerosis, Thrombosis, and Vascular Biology , Wang et al9 investigate the expression of human apo A-II in transgenic rabbits on lipoprotein metabolism and atherosclerosis. Although rabbits have many advantages over mice as animal models for atherosclerosis, such as the expression of CETP, there have only been few previous reports of transgenic rabbits being used to study atherosclerosis.10,11 One important difference between rabbits and humans in lipoprotein metabolism, which facilitated this …
Marx’s Gendered Temporalities

Massimiliano Tomba’s book, Marx’s Temporalities, stresses the centrality of the body for the critique of exploitation and suggests that a new phenotype is produced by consumerism and by the dynamic of capitalist accumulation, with its plural temporalities. However, both the body of the worker and the new phenotype do not appear to have a sex or a gender in Tomba’s book. In this intervention, I read some of Tomba’s insights about the body, the new phenotype, and primary accumulation in the light of a critical gender and feminist perspective.
Student Reflections on Service Learning: Cognitive, Affective and Behavioral Lessons

Service-learning is an educational experience that allows students meaningful interaction with older adults. Students in a gerontology course completed service-learning and recorded their experiences in weekly journals. This study explored student-reported reflections, which indicated cognitive, affective and behavioral lessons. Future research should include the perspectives of faculty members, agencies and older adults, long-term influences of service, and approaches to facilitating service learning for hybrid and online courses.
/sup 17/O(/sup 3/He,p)/sup 19/F and the structure of /sup 19/F

Angular distributions have been measured for 18 levels of $^{19}\mathrm{F}$ populated in the reaction $^{17}\mathrm{O}$($^{3}\mathrm{He}$,$p$) at a bombarding energy of 18 MeV. Within the experimental resolution of 28 keV all levels below 5.7 MeV were observed. Nine states were excited with peak differential cross sections greater than 50 \ensuremath{\mu}b/sr, all others had maximum cross sections of less than 12 \ensuremath{\mu}b/sr. Eight of the nine strong levels are easily identifiable with ${(\mathrm{sd})}^{3}$ shell-model states. The ninth is the state at 5.11 MeV, previously assigned ${J}^{\ensuremath{\pi}}=\frac{5}{{2}^{\ensuremath{-}}}$, but suggested by the present results to have positive parity. Angular distributions were analyzed with the distorted-wave Born approximation. For the strong states, transfer amplitudes were taken from an ${(\mathrm{sd})}^{3}$ shell-model calculation. Agreement in both shape and magnitude is good. Negative-parity hole states and positive-parity core-excited states are very weakly populated, but in many cases, their angular distributions are also well fitted with admixtures of the allowed $L$ values.NUCLEAR REACTION $^{17}\mathrm{O}$($^{3}\mathrm{He}$,$p$), $E=18.0$ MeV; $^{19}\mathrm{F}$ deduced levels, $L$, $\ensuremath{\Pi}$.

Spectroscopic data for infrared transitions in CaGa2S4:Dy3+ and KPb2Cl5:Dy3+

We have identified two low phonon energy hosts that we believe will allow lasing in the mid-IR spectral region (4-10 μm). CaGa2S4 (calcium thiogallate) and KPb2Cl5 (potassium lead chloride) are both non-hygroscopic and readily incorporate rare earth ions. Spectroscopic data for these two crystalline hosts are presented, and the possibility of lasing in the mid-IR at room temperature is discussed.
Managing technical professionals: bottom performers in an organization

AS we reach mid-year, most organizations will begin reviews with employees. During these reviews, managers discuss the technical and professional performance with individuals in their organizations. These employee reviews are based on performance metrics established earlier in the year. Whether the individual's performance has been strong or needs improvement is determined based on these metrics. If the manager has been providing timely feedback to the employee, these mid-year reviews should not require a great deal of time and there should be no surprises. As an example, I have weekly meetings with my direct reports and I provide feedback to them about the wonderful things they do, and identify issues where they can improve, so the mid-year review meetings with my direct reports are usually done very quickly and there are no surprises, unless something happened since our last weekly meeting.
Neural Blockade in the Evaluation and Management of Chronic Pain: An Overview

Local anesthetic and neurolytic nerve blocks have been used for over a century in the evaluation and management of chronic pain, despite a the dearth of evidence supporting their application. This article provides a general overview of the physiology and pharmacology of nerve blocks and suggests how they may affect pathophysiological mechanisms of chronic pain. Following a discussion of the rationale, clinical application and potential complications of nerve blocks, existing evidence of efficacy is reviewed. Further research evaluating mechanisms and efficacy of nerve blocks is vital to define their role in chronic pain management.
Universal Microcarriers for Microfluidic Assays

Bead and cell suspension based flow-through assays are popular for high throughput biological analysis. Several technologies incorporate a tagging scheme with beads to enable multiplexing. Modern flow-through systems such as flow cytometers and cell sorters are large, bulky and expensive; consequently, much research has been performed using microfluidics to miniaturize these systems. However, several problems remain with these systems, notably it remains difficult to perform manipulations on the beads (or cells), and in the case of multiplexed systems, it remains difficult to read the tags quickly. In this paper, we present a micromachined micro-carrier, referred to as a ‘micropallet’, designed to move through a microfluidic device, which helps to solve several of these problems. Micropallets are small carrier structures, micromachined out of plastic or other materials, that are used to carry attached biological or chemical samples through a microfluidic system (e.g., DNA, RNA, proteins, antibodies, adherent cells, organisms). Similar to conventional factory pallets that carry a product through an automated manufacturing line, micropallets are engineered to carry their cargo through a micro-scale system. Thus micropallets may contain shapes, structures and materials designed to interact with and work in a microfluidic system, such as for docking, sorting, manipulation and readout. Additionally, micropallets may include bar codes or other markings, and be engineered to optimally suit the cargo they carry (for example, a micropallet might contain 3-D structures and treated sections for cells, molecules or organisms to attach). Results are presented for the use of micropallets in cell assays, DNA assays and antibody assays.

Research on the Disposal of Rural High-fluorine Groundwater by Self-made Defluorinating Agents Prepared with Bone Chars

The defluorinating agent of bone chars is made from domestic animal bones under different conditions,and by comparing the fluoride removal effects of the bone chars the most well-prepared methods of the defluorinating agent are sifted out.In the process of static adsorption experiment,the effects of different influencing factors such as temperature,pH and bone char dosage on the fluoride removal effect of bone char are investigated.The experiment results indicate that temperature has little impact on fluoride removal effect of the bone char;and low pH condition can promote the bone char to remove fluoride;in addition,Ca2+ and Mg2+ improved fluoride removal effect of the bone char to a certain degree.However,the anions inhibits its fluoride removal effect to some extent.The used bone char can be regenerated by NaOH,and the adsorption amount of the bone char that has been regenerated for three times still reaches 94.3% to the initial value,which shows that the defluorinating agent of bone chars has good regeneration ability and can be used to remove fluoride repeatedly.
A solution to knowledge’s threshold problem

This paper is about the ‘threshold problem’ for knowledge, namely, how do we determine what fixes the level of justification required for knowledge in a non-arbitrary way? One popular strategy for solving this problem is impurism, which is the view that the required level of justification is partly fixed by one’s practical reasoning situation. However, this strategy has been the target of several recent objections. My goal is to propose a new version of impurism that solves the threshold problem without succumbing to these criticisms.
A retrospective analysis of medical record use in e-consultations

Introduction Under certain circumstances, e-consultations can substitute for a face-to-face consultation. A basic requirement for a successful e-consultation is that the e-consultant has access to important medical history and exam findings along with laboratory and imaging results. Knowing just what information the specialist needs to complete an e-consultation is a major challenge. This paper examines differences between specialties in their need for past information from laboratory, imaging and clinical notes. Methods This is a retrospective study of patients who had an internal e-consultation performed at an academic medical centre. We reviewed a random sample of e-consultations that occurred in the first half of 2013 for the indication for the e-consultation and whether the e-consultant reviewed data in the medical record that was older than one year to perform the e-consultation. Results Out of 3008 total e-consultations we reviewed 360 (12%) randomly selected e-consultations from 12 specialties. Questions on management (35.8%), image results (27.2%) and laboratory results (25%) were the three most common indications for e-consultation. E-consultants reviewed medical records in existence more than one year prior to the e-consultation 146 (40.6%) of the time with e-consultants in the specialties of endocrinology, haematology and rheumatology, reviewing records older than one year more than half the time. Labs (20.3%), office notes (20%) and imaging (17.8%) were the types of medical data older than one year that were reviewed the most frequently overall. Discussion Management questions appear to be the most common reason for e-consultation. E-consultants frequently reviewed historical medical data that is older than one year at the time of the e-consultation, especially in endocrinology, haematology and rheumatology specialties. Practices engaging in e-consultations that require transfer of data may want to include longer time frames of historical information for those specialties.

Socioeconomic Conditions and Discursive Construction of Women’s Identities in Post-Soviet Countries

What happens when certain identities are no longer legitimized or validated by society? The goal of the present chapter is to understand the impact of radical historical and socioeconomic changes on discursive construction of identity, in particular, on subjectivities available in a specific society at a specific point in time. The current situation in post-Soviet countries provides a unique opportunity to explore this issue by examining lives caught in a rapidly shifting social reality. I will focus my analysis on the concept of womanhood as it is constituted, transformed and redefined in post-Soviet discourses. I will begin by comparing the political and economic situation of women in Soviet and in post-Soviet times, linking the socioeconomic conditions to discursive positions assigned to women by the preeminent ideologies before and after 1991, since at all times notions of acceptable femininities are closely tied to economic conditions and the distribution of wealth (Burr, 1998; Gal, 1978).
On deciding synchronizability for asynchronously communicating systems

Abstract Asynchronously communicating systems involve peers or entities that communicate by exchanging messages via buffers. In general, the size of such buffers is not known apriori, i.e., they are considered to be unbounded. As a result, models of asynchronously communicating systems typically exhibit infinite state spaces and it is well-known that reachability and boundedness problems for such models are undecidable. This, in turn, makes automatic verification of asynchronous systems undecidable as well. We discuss a particular class of asynchronous systems over peers for which the interaction behaviors do not change when the peers are made to communicate synchronously. Such systems are referred to as Synchronizable . Automatic verification of synchronizable systems is decidable as the verification of the system can be performed using its synchronous counterpart. Recently, we have proved that checking whether or not a system is synchronizable is decidable. In this paper, we consider different types of asynchronous communication, where the type is described in terms of the nature of buffering and the number of buffers, and discuss how/if synchronizability is decidable for each type. The new results subsume the existing ones and present a comprehensive synchronizability study of asynchronous systems.
Qualifications and Competencies for Population Health Management Positions: A Content Analysis of Job Postings

Abstract The need for population health management expertise has increased as the health care industry shifts toward value-based care. However, many organizations report hiring gaps as they seek to fill positions. The purpose of this study was to analyze the types of population health management positions for which health care organizations are hiring, including qualifications and competencies required for these positions. A content analysis was conducted on 271 job postings collected during a 2-month period. A typology of qualifications and competencies was developed based on the content analysis. Profiles were generated for the top 5 job title classifications: directors, coordinators, care managers, analysts, and specialists. This study highlights the investment health care organizations are making in population health management and the prominent role these positions are playing in the health care environment today. Many organizations are building out population health management teams resulting in mul...

Solar flare prediction using multivariate time series decision trees

Space Weather is of rising importance in scientific discipline that describes the way in which the Sun and space impact a myriad of activities down on Earth as well as the safety of the space crew members on board of the space stations. Consequently, it is imperative to better quantify the risk of future space weather events. Most of the flare prediction models in literature use physical parameters of the potentially flaring active regions during a limited interval to gain insights on whether a flare will happen or not. This limits our perception of how an event evolves for an extended duration across multiple parameters. In this paper we followed a data-driven approach to address the problem of flare prediction from a multivariate time series analysis perspective and attempt to cluster potential flaring active regions by applying Distance Density clustering on individual parameters and further organize the clustering results into a multivariate time series decision tree. We compared different data extraction priors and spans, and ranked the importance for different parameters through univariate clustering. To the best of our knowledge, this is the first attempt to predict solar flares using a tree structure.
