Legal issues in pediatric interfacility transport

Abstract Interfacility transport evolved because of the need for transport of ill or injured patients from one medical facility to another. Optimally this is accomplished in a safe, efficient, and medically expert fashion, and is always in the best interest of the patient. Interfacility transport systems vary by capabilities, equipment, personnel, and missions. Expert medical and logistical information is necessary before the implementation and use of such systems. While not usually at the forefront of planning for medical implementation, the legal issues, requirements, and restrictions inherent in interfacility transport are significant and must be considered. This article will review legal issues surrounding interfacility transport and identify potential pitfalls.
New design formulation of chemical reactors with multiple reactions: I. basic concepts

Abstract A new approach to formulate the design of chemical reactors with multiple reactions is presented. The new design methodology is applicable for all reactor configurations, any number of chemical reactions, having any form of rate expressions. Reactor operations are formulated in terms the smallest set of dimensionless design equations and their solutions provide dimensionless operating curves, indicating progress of the chemical reactions, species compositions and the temperature variations without considering the reactor size or operating time. Reactor sizing represents a “point” on these operating curves and the required volume is readily determined for a specified feed rate and given reaction rates. The design is formulated using the least number of terms in each design equation, thus providing the most robust set of equations for numerical solutions. The methodology also provides new design capabilities for reactor configurations whose designs are not available in the literature. Part I presents the basic concepts of the new approach and illustrates how they are applied.
Preparation of CdS Nanoparticles in Salt-Induced Block Copolymer Micelles

A novel preparation method of CdS nanoparticles with controllable size and stability is presented. Poly(styrene-block-2-vinylpyridine) (PS-b-P2VP) and cadmium ions form aggregates of single micelles called compound micelles, upon addition of the cadmium acetate salt into a solution of the block copolymer in tetrahydrofuran. The growth of CdS nanoparticles is confined to the core of single micelles after introduction of hydrogen sulfide gas into the solution. UV−visible spectroscopy, fluorescence spectroscopy, and transmission electron microscopy were employed to characterize the prepared nanoparticles. UV−visible absorption spectra show that larger nanoparticles are produced at lower 2VP:Cd2+ molar ratio. UV−visible absorption spectra and fluorescence spectra both indicate that with a decrease of block copolymer concentration in tetrahydrofuran, the size of the CdS nanoparticles decreases. The stability of the CdS nanoparticles and micelles was also investigated. UV−visible results show that the prepared ...
Interaction of chromatid breaks produced by x-rays and radiomimetic compounds.

S>The results of combination treatments of the roots of V. faba with centain radiomimetic compounds (8ethoxycaffeine, maleic hydrazide, beta - propiolactone, and potassium cyanide) and x ray, as well as combination treatments of certain radiomimetic compounds with one another, were observed to determine whether interaction will occur between chromosomal breaks induced by different agents. Interaction was observed between breaks induced by x rays and all of the breaks induced by chemicals but not between breaks induced by any two chemicals. Ths results are discussed in terms of possible breakage bond differences and the effects of temporal and spatial differences in breaks induced by different agents. (auth)
Postbuckling and vibration of linearly elastic and softening columns under self-weight

The critical height for buckling of a linearly elastic cantilevered column due to its self-weight was determined by Greenhill in 1881. Postbuckling behavior also has been studied, often assuming that the column is an elastica (inextensible, with its bending moment proportional to its curvature). The bifurcation point at the critical height is supercritical, so that the postbuckling path is stable as the height increases past its critical value. Subcritical bifurcation may occur if the column is nonlinearly elastic with a softening behavior. This results in a sudden jump from the straight vertical configuration to a severely-drooped shape. The governing equation is solved numerically with the use of a shooting method to obtain the equilibrium paths. Also, small vibrations about the straight and postbuckled equilibrium states are examined, and vibration frequencies (and hence stability properties) are obtained. An initial curvature of the column is included in the analysis. Experiments are conducted to verify the results qualitatively for linearly elastic and softening materials.
Analysis of a multistage inventory task: Comments on a paper by amnon rapoport

In an interesting paper in Behavioral Science, Volume 12 (1967), Amnon Rapoport reported on his tests of the dynamic decision-making capabilities of a group of students. He found that the students did not perform well relative to the normative results predicted by two quantitative inventory models he had chosen. It is the purpose of this paper to point out that the wrong normative models were chosen and that if the appropriate inventory model had been picked, the students may have performed reasonably well.
Review : Mapping Brain Pathophysiology and Higher Cortical Function with Magnetic Resonance Imaging

Advances in magnetic resonance imaging (MRI) have moved the technology beyond its application solely as a diagnostic test to become a tool for addressing questions of in vivo pathophysiology and higher cortical function in humans. Diffusion-weighted MRI measures the apparent rate of translational movement of water molecules through brain parenchyma. This measurement can be used to determine axonal orientation within white matter, to define regions of tissue edema, and to permit early identification of ischemic neuronal injury related to impairment of Na+-K +-ATPase activity in experimental and human stroke. Changes in various aspects of cerebral perfusion—blood volume, blood flow, and hemoglobin oxygen saturation—can be mea sured with MRI, and altered cerebrovascular circulation and regional brain activation can thereby be inves tigated. Echo planar imaging is a method of ultrafast data acquisition with MRI—individual images are ac quired on the order of 100 msec. Echo planar imaging makes diffusion and p...

Aromatizable vs non-aromatizable androgens in cervical ripening

SAROSH RANA (F), HUILING JI, VIT LONG, EDWARD CHIEN, Brown University, Women and Infants Hospital of Rhode Island, Providence, Rhode Island, Brown University, Obstetrics and Gynecology, Providence, Rhode Island OBJECTIVE: The regulation of cervical remodeling during pregnancy is poorly understood but is thought to be regulated by steroid hormones. A number of model systems with androgen metabolism abnormalities have disturbances in cervical ripening. These models would suggest that nonaromatizable androgens directly control cervical ripening. 5a-reductase type II converts testosterone to DHT (Dihydrotestosterone), a non-aromatizable androgen. We hypothesize that cervical remodeling is mediated through androgens leading to decreased cervical tensile strength. STUDY DESIGN: Cervical creep (an assessment of tensile strength) was assessed in timed pregnant Sprague-Dawley rats at mid gestation. Treatment groups included three androgenic compounds: Androstenedione (20 mg), Testosterone (2 mg), and DHT (2 mg). Cervical creep was determined using the technique of Hollingsworth. Androgens were administered intravaginally on day 15. Tissue was harvested 16 hrs later. Groups were compared to control using t-test. RESULTS: A significant increase in cervical creep rates were seen after DHT (p = 0.01). No statistically significant difference was detected in rats treated with androstenedione or testosterone when compared to rats in the control group. The effect of testosterone had greater variability then androstenedione or DHT CONCLUSION: The non-aromatizable androgen, DHT, is an effective cervical ripening agent. The conversion of aromatizable androgens to DHT is necessary for androgen induced cervical ripening.
A technique to determine power-efficient, high-performance superscalar processors

Processor performance advances are increasingly inhibited by limitations in thermal power dissipation. Part of the problem is the lack of architectural power estimates before implementation. Although high-performance designs exist that dissipate low power, the method for finding these designs has been through trial-and-error. The paper presents systematic techniques to find low-power, high-performance superscalar processors tailored to specific user benchmarks. The model of power is novel because it separates power into architectural and technology components. The architectural component is found via trace-driven simulation, which also produces performance estimates. An example technology model is presented that estimates the technology component, along with critical delay time and real estate usage. This model is based on case studies of actual designs. It is used to solve an important problem: increasing the duplication in superscalar execution units without excessive power consumption. Results are presented from runs using simulated annealing to maximize processor performance subject to power and area constraints. The major contributions of the paper are the separation of architectural and technology components of dynamic power, the use of trace-driven simulation for architectural power measurement, and the use of a near-optimal search to tailor a processor design to a benchmark. >
A unique fault-tolerant design for flying capacitor multilevel inverters

This paper presents a unique design for flying capacitor type multilevel inverters with fault-tolerant features. When a single-switch fault per phase occurs, the new design can still provide the same number of converting levels by shorting the fault power semiconductors and reconfiguring the gate controls. The most attractive point of the proposed design is that it can undertake the single-switch fault per phase without sacrificing power converting quality. Future more, if multiple faults occur in different phases and each phase have only one fault switch, the proposed design can still conditionally provide consistent voltage converting levels. This paper will also discuss the capacitor balancing approach under fault-conditions, which is an essential part of controlling flying capacitor type multilevel inverters. Suggested fault diagnosing methods are also discussed in this paper. Computer simulation and lab results validate the proposed controls.
Metastability and Crystallization in Hard-Sphere Systems.

We present results of large-scale molecular dynamics simulations of hard sphere systems at values of the volume fraction $\ensuremath{\varphi}$ along the disordered, metastable branch of the phase diagram up to random close-packing ${\ensuremath{\varphi}}_{c}$. By quantifying the degree of local order, we determine the necessary conditions to obtain a truly random system, enabling us to compute the pressure carefully along the entire metastable branch. Near ${\ensuremath{\varphi}}_{c}$ we show that the pressure scales as $({\ensuremath{\varphi}}_{c}\ensuremath{-}\ensuremath{\varphi}{)}^{\ensuremath{-}\ensuremath{\gamma}}$, where $\ensuremath{\gamma}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$ and ${\ensuremath{\varphi}}_{c}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.644\ifmmode\pm\else\textpm\fi{}0.005$. Contrary to previous studies, we find no evidence of a thermodynamic glass transition and find that after long times the system crystallizes for all $\ensuremath{\varphi}$ above the melting point.
Tuberculosis and Poverty: Why Are the Poor at Greater Risk in India?

Background Although poverty is widely recognized as an important risk factor for tuberculosis (TB) disease, the specific proximal risk factors that mediate this association are less clear. The objective of our study was to investigate the mechanisms by which poverty increases the risk of TB. Methods Using individual level data from 198,754 people from the 2006 Demographic Health Survey (DHS) for India, we assessed self-reported TB status, TB determinants and household socioeconomic status. We used these data to calculate the population attributable fractions (PAF) for each key TB risk factor based on the prevalence of determinants and estimates of the effect of these risk factors derived from published sources. We conducted a mediation analysis using principal components analysis (PCA) and regression to demonstrate how the association between poverty and TB prevalence is mediated. Results The prevalence of self-reported TB in the 2006 DHS for India was 545 per 100,000 and ranged from 201 in the highest quintile to 1100 in the lowest quintile. Among those in the poorest population, the PAFs for low body mass index (BMI) and indoor air pollution were 34.2% and 28.5% respectively. The PCA analysis also showed that low BMI had the strongest mediating effect on the association between poverty and prevalent TB (12%, p = 0.019). Conclusion TB control strategies should be targeted to the poorest populations that are most at risk, and should address the most important determinants of disease—specifically low BMI and indoor air pollution.
Physiology and Endocrinology of Hot Flashes in Prostate Cancer

The purpose of this article is to integrate the physiology of the male reproductive system and the role of hormones in the pathophysiology and treatment of prostate cancer. The primary focus is to review hormonal changes associated with androgen ablation treatment and to integrate the available hormonal data into a hypothesis. This review used a systematic search of Medline references from 1990 to 2006. All sources were critically evaluated to arrive at an understanding of androgen deprivation symptoms, such as hot flushes/flashes, and to identify research needed in this area. Research is needed to explore the physiological mechanisms of hot flashes to develop better therapeutic treatment options to ameliorate side effects of hormonal treatment. Studies are needed to investigate all aspects of hot flashes in populations other than those with breast cancer, such as men with prostate cancer, carcinoid tumors, medullary thyroid tumors, pancreatic islet-cell tumors, renal cell carcinoma, and phenochromocytoma.
Molecular Basis of Evolutionary Loss of the α1,3-Galactosyltransferase Gene in Higher Primates

Galactose-α1,3-galactose (αGal) epitopes, the synthesis of which requires the enzyme product of α1,3-galactosyltransferase (α1,3GT), are sugar chains on the cell surface of most mammalian species. Notable exceptions are higher primates including Old World monkeys, apes, and humans. The αGal-negative species as well as mice with deletion of the α1,3GT gene produce abundant anti-αGal antibodies. The evolutionary loss of αGal epitopes has been attributed to point mutations in the coding region of the gene. Because no transcripts could be found in the higher primate species with Northern blot analysis, a potential alternative explanation has been loss of upstream regulation of the gene. Here, we have demonstrated that the rhesus promoter is functional. More importantly, a variety of full-length transcripts were detected with sensitive PCR-based methods in the tissues of rhesus monkeys, orangutans, and humans. Five crucial mutations were delineated in the coding region of the human and rhesus and three in the orangutan, any one of which could be responsible for inactivation of the α1,3GT gene. Two of the mutations were shared by all three higher primates. These findings, which elucidate the molecular basis for the evolutionary loss of αGal expression, may have implications in medical research.
On Structural Properties of the Lyapunov Matrix Equation for Optimal Diagonal Solutions

We revisit the classical problem of finding a positive diagonal solution P to the Lyapunov equation AT P + PA < 0 that minimizes the Lyapunov exponent (the maximum eigenvalue of AT P + PA) for A isin RnXn, with the aim of identifying structural properties of the Lyapunov matrix equation at the optimum. Using eigenvalue sensitivity notions together with optimization machinery, we are able to obtain an explicit characterization of the minimum Lyapunov exponent that provides such structural insight.
Estimated healthcare savings associated with adequate dairy food intake.

Medical literature that has coalesced during the past two to three decades has identified adequate intake of nutrients from dairy foods as a common factor in the reduction of the disease burden of several common medical conditions. These include obesity, hypertension, type 2 diabetes, osteoporosis, kidney stones, certain outcomes of pregnancy, and some cancers. Treatment of these disorders, particularly cardiovascular, consumes a significant portion of the United States' healthcare budget. Drawing on accumulated data from prospective longitudinal studies and randomized controlled trials, this article summarizes the evidence of the net benefits of increased dairy food intake on these conditions, their outcomes, and their costs. Estimated improvements in outcomes were combined with available data on annual costs of the respective disorders. From the calculated annual impact, we generated first-year and fifth-year healthcare cost savings that would accrue if adult Americans simply increased their intake of dairy foods to the currently recommended 3 to 4 servings/d. Using conservative estimates of potential benefit, we project first-year savings of approximately $26 billion and 5-year cumulative savings in excess of $200 billion.
The Cross-Cultural Perspective in the Study of Personality: Rationale and Current Research

In this article, we examine the rationale for cross-cultural studies of personality, (including the search for cultural universals). Note the uncertain cross-cultural relevance of mainstream personality theories, and address current cross-cultural research on the following personality-relevant topics: personality structure and assessment, implications of individualism-collectivism for traits and their measurement, values and beliefs, emotions and subjective well-being, and motivation. Some of the best support for cross-cultural universality has been obtained in studies of the five-factor model of personality, the content and structure of values, a limited number of basic emotions, and higher order mood dimensions. Topics that need to be studied further include the following: (a) how to separate the many factors that influence personality scores across cultures, (b) the degree of cross-cultural comparability of the nomological nets of personality dimensions, and (c) the integration of trait-psychology and ...
Private security forces and African stability: the case of Executive Outcomes

The end of the Cold War has had contradictory effects on African security. Southern Africa and Ethiopia clearly benefitted from the end of superpower rivalry, whereas central and western Africa have seen an upswing of violence during the 1990s. The withdrawal of foreign patronage, the post-Somalia reluctance of the West and the UN to intervene militarily, heightened external demands for economic and political reform, and the changing nature of African insurgencies, have placed additional pressure on already weak governments. Many African states have only weak militaries to defend their security, the collapse of Mobutu Sese Seko's Armed Forces of Zaire providing the most recent example.As recently as 1990, the idea of African states relying upon mercenaries from the former South African Defence Force (SADF) would have seemed both preposterous and insulting. Yet since 1993, Executive Outcomes (EO), the world's largest and best known ‘mercenary’ group, has marketed itself as a defender of African state security in this post-Cold War era. A private army with access to some 2,000 ex-South African Defence Force (SADF) combat veterans, EO has helped to defeat discredited insurgencies in Angola and Sierra Leone. Large sections of Africa need effective militaries and EO, which claims to fight only for sovereign governments, presents itself as a stabilising force for African development. To some observers, EO is ‘with the possible exception of the South African army, the most deadly and efficient army operating in sub-Saharan Africa today’.This article examines the controversial Executive Outcomes military as a security option for African governments. It sketches EO's history, its military effectiveness, and its political loyalty, to assess whether EO threatens or assists African state stability. The article concludes by looking at EO's possible future, and the lessons which it offers about African security.
CHRISTIAN ORTHODOXY AND RELIGIOUS PLURALISM

The paper argues that it can be demonstrated that the position of Jacques Dupuis, S.J., a pluralist, is compatible with that of the syllabus on religious pluralism produced by the Roman Catholic Congregation for the Doctrine of the Faith, Dominius Iesus. This demonstration provides good reason to believe that at least one form of de jure pluralism, labeled “inclusivist pluralism”, is a theological theory compatible with orthodox Christian belief.
Optical Quality Requirements For Large Mirror Systems

A methodology is discussed for defining mirror quality requirements (as a function of spectral bandpass, type of object being viewed and type of background). The application of the methodology to several current and future large mirror systems is described. The major parameter is the surface power spectral density function; means of proper specification and measurement are discussed, along with their impact on encircled energy and scatter. The effects of diffraction are considered, including low, mid-, and high spatial frequency surface errors and surface "quilting" associated with large lightweighted mirrors.

Sanitary Policing and the Local State, 1873–1874: A Statistical Study of English and Welsh Towns

This article examines local sanitary policing in extra-metropolitan English and Welsh towns and cities in the period 1873-4. It combines two parliamentary returns, one focusing on the appointments by towns of sanitary officers (inspectors of nuisances and medical officers), the other listing the number of nuisance cases and modes of resolutions. The article uses these databases to examine the identification of nuisances in terms of region, town type, mode of government, population, and salary of inspector. It considers also the effects of tenure and job security on nuisances identification, the effects of town wealth, and differences in the resolution of nuisance allegations by town type and region. The article shows a remarkable and perhaps unexpected sanitary activism, but also a considerable variability by region, town size, and town type.
Notation of Depression in Case Records of Older Adults in Community Long-Term Care

Although significant numbers of social service clients experience mental health problems, virtually no research has examined the responsiveness of social service agencies to mental disorder. This article examines the extent to which client depression is reflected in records of a public social service agency, community long-term care (CLTC). Researchers assessed new, consenting CLTC clients for depression using standardized research criteria in a telephone interview. Agency case records were abstracted to determine the extent to which client depression was noted. Sensitivity and specificity of depression notation were 25.21 percent and 92.80 percent, respectively, indicating that agency records reflected depression for about one in four clients meeting depression criteria. Factors associated with accurate depression notation included cognitive impairments, low social support, psychotropic medications, and mental health treatment. The depression notation rates found are comparable to those in medical settings. Structured screening and assessment might enhance detection of mental disorder for social service clients.
Heightened Sensitivity to Paclitaxel in Class IVa β-Tubulin-transfected Cells Is Lost as Expression Increases *

Stably transfected Chinese hamster ovary cell lines expressing increasing levels of β4a, a class IV neuronal-specific β-tubulin, were compared for effects on microtubule organization, assembly, and sensitivity to antimitotic drugs. It was found that β4a reduced microtubule assembly in proportion to its abundance and thereby caused supersensitivity to microtubule disruptive drugs such as colcemid, vinblastine, and nocodazole. However, the response to paclitaxel was more complex. Low expression of β4a caused supersensitivity to paclitaxel, whereas higher expression resulted in the loss of supersensitivity. The results suggest that β4a may possess an enhanced ability to bind paclitaxel that increases sensitivity to the drug and acts substoichiometrically. At high levels of β4a expression, however, microtubule disruptive effects counteract the assembly promoting pressure exerted by paclitaxel binding, and drug supersensitivity is lost. β4a-Tubulin differs from the more ubiquitous β4b isotype at relatively few amino acid residues, yet β4b expression has little effect on microtubule assembly or drug response. To determine which amino acids mediate the effects of β4a expression, β4a and β4b were altered by site-directed mutagenesis and expressed in Chinese hamster ovary cells. The introduction of N332S or N335S mutations into β4b-tubulin was sufficient to confer microtubule disruption and increased colcemid sensitivity. On the other hand, mutation of Ala115 to serine in β4a-tubulin almost completely reversed heightened sensitivity to paclitaxel, but introduction of an S115A mutation into β4b had no effect, suggesting that a complex interaction of multiple amino acids are necessary to produce this phenotype.
The NCAA: A Socio‐economic Analysis: The Development of the College Sports Cartel from Social Movement to Formal Organization.

. Economic cartel theory and Sociological social movement theory are used to achieve a socio-economic analysis of the problems and behaviour of the National Collegiate Athletic Association (NCAA). It is demonstrated that both cartel theory and social movement theory predict substantially similar behavior on the part of the NCAA and its 800-plus member institutions. Specific issues such as “need”scholarships, the possibility that the” big-time”football powers, may leave the NCAA, and the NCAA's relation with women's athletics, are considered. It is concluded that the NCAA is not likely to persist is an organization in its current form.
Some p-ranks related to Hermitian varieties

Abstract We determine the p-rank of the incidence matrix of hyperplanes of PG(n, pe) and points of a nondegenerate Hermitian variety. As a corollary, we obtain new bounds for the size of caps and the existence of ovoids in finite unitary spaces. This paper is a companion to an earlier work in which Blokhuis and this author (J. Algebraic Combin. 4 (1995), 295–316) derive the analogous p-ranks for quadrics.
Management and outcomes of dialysis access-associated steal syndrome

Objective Dialysis access-associated steal syndrome (DASS) complicates arteriovenous access surgery. We describe a 10-year experience with the surgical management of DASS. Methods DASS operations were retrospectively reviewed from July 2003 to July 2013 from a single academic institution. Demographics, symptoms, surgical details, and outcomes were collected. Results A total of 201 patients had 218 episodes of DASS. Mean age was 65 years, and 62% were women. DASS was caused by 175 arteriovenous fistulas (80%), 41 upper extremity prosthetic grafts (19%), and two thigh grafts (1%); 87% were brachial artery based. A portion (22%) were referred for DASS from outside practices. All patients had grade 2 (48%) or grade 3 (52%) DASS; 92% (185) were available for follow-up, with a median time to first follow-up of 23 days. Surgical procedures included ligation (73), distal revascularization with interval ligation (DRIL) (59), revision using distal inflow (RUDI) (21), banding (38), proximalization of arterial inflow (12), and distal radial artery ligation (13). There were no differences in preoperative comorbidities between treatment groups. The 30-day complications included continued steal, thrombosis, bleeding, infection, and mortality. Ligation and DRIL were performed most often for grade 3 steal. Ligation and banding were performed most acutely (median time to intervention after access creation of 39 and 24 days vs DRIL and RUDI at 97 and 100 days). Fistula preservation was 0% for ligation, 100% for DRIL, 95% for RUDI, and 89% for banding ( P P = .005). Women were less likely to have DRIL but more likely to have ligation ( P = .001). Complications were highest in the banding (49%) and RUDI (37%) groups. Average mortality was 3.5%, with no significant differences among groups. During the study period, 3287 access procedures were performed, and access volume steadily increased (2003-2008, 1312 access creations; 2008-2013, 1975). Percentage of fistulas (79% vs 86%), incidence of steal (4% vs 6%), and percentage of DRILs (25% vs 28%) were consistent across the two study periods. Conclusions DRIL and ligation were performed in patients with the most severe symptoms. Compared with ligation, DRIL has equal symptom resolution, no increase in complications, and fistula preservation. Compared with banding, DRIL resulted in superior fistula preservation and fewer complications. DRIL should be considered the preferred procedure for management of DASS in patients with a functioning autologous fistula who can tolerate a major operation.
Examining the Unique Characteristics of Economics: A Description of a Student Assignment

Abstract This article discusses a classroom activity which introduces students to the knowledge creation process in the field of economics. Although the assignment was used in an upper level history of economic thought class, it could be tailored to fit almost any broadly themed course in the field. Economics is a discipline that faithfully adheres to a particular approach—one based on self-interest and contractual exchange; ideas that deviate from this approach are often overlooked by economists or deemed outside the discipline. Likewise, arguments made without the use of core assumptions or mathematical models are screened out as not truly being economics. Due to this allegiance to a specific form of argument, economics has developed unique characteristics. The class activity asks students to think about the implications of these characteristics and identity economic models and theories that exemplify them.
Shoulder Pain: A Presentation of Bilateral Gonococcal Arthritis of the Shoulders

Abstract This is a report of a 47-year-old man presenting to the Emergency Department complaining of bilateral shoulder pain after developing pain in the right shoulder about 1½–2 weeks prior after heavy lifting while at work. Clinical suspicion of Gonococcal arthritis was confirmed on the basis of laboratory studies. Although Gonococcal arthritis is occasionally associated with uniarticular arthritis, this patient presented with bilateral joint involvement.
Web-based automated assessment for ABET programs

The College of Engineering has developed several innovative tools to automating the processes of assessment and evaluation of outcomes of university, college of engineering and individual ABET engineering programs. The authors develop algorithms and mathematical models, then directly write computer code or work with software engineering students to develop the software. This same team provides workshops to demonstrate to students, advisors and faculty the value and use of these web-based tools. Quantitative information is automatically plotted and users most recent results displayed relative to historical trends. One example is the Texas Tech "Mock FE" administered by the college to senior students two weeks prior to the Fundamentals of Engineering (FE) Exam. An individual's results of this four-hour test are available to each student and plotted relative to historical trends thus allowing each student to predict his/her performance on the FE relative to each subject.
Control of Motor Output

Considerable evidence indicates that proprioceptive feedback from moving limbs does not contribute information used by the central nervous system in generating locomotor patterns. The basic motor score is determined by patterned activity in central neurons, or by the inhibitory and/or excitatory connections between them; such scores are usually genetic, but could in principle result from autogenetic interactions between the CNS and the environment or the body periphery. Separate centers for the production of cyclic output (as, for example, in different limb-bearing segments) are held in particular phase relations by interconnections that carry replicas of the motor output from one center to another. These messages formally resemble the ‘efference copy’ of von Hoist. The output of the ensemble is commanded by neurons that trigger the pattern but do not contribute to its structure.
Pressure-induced phase transition in La 1 − x Sm x O 0.5 F 0.5 BiS 2

Electrical resistivity measurements on La1–xSmxO0.5F0.5BiS2 (x = 0.1, 0.3, 0.6, 0.8) have been performed under applied pressures up to 2.6 GPa from 2 K to room temperature. The superconducting transition temperature Tc of each sample significantly increases at a Sm-concentration dependent pressure Pt, indicating a pressure-induced phase transition from a low-Tc to a high-Tc phase. At ambient pressure, Tc increases dramatically from 2.8 K at x = 0.1 to 5.4 K at x = 0.8; however, the Tc values at P > Pt decrease slightly with x and Pt shifts to higher pressures with Sm substitution. In the normal state, semiconducting-like behavior is suppressed and metallic conduction is induced with increasing pressure in all of the samples. Furthermore, these results suggest that the pressure dependence of Tc for the BiS2-based superconductors is related to the lattice parameters at ambient pressure and enable us to estimate the evolution of Tc for SmO0.5F0.5BiS2 under pressure.

Impact of Industrialization in Nigeria

The objective of this study is to analyze the relationship between GDP, agriculture (AR), industry (ID) and services sector (SV) in Nigeria. The Johansen co-integration testing approach demonstrates a significant long-run relationship between these three variables. The results reveal that agriculture, industry and services have a significant positive relationship with GDP. The Causality results demonstrate a bidirectional causal relationship between GDP, AR, ID and SV. It is suggested therefore that it is important to develop the agricultural sector to provide the needed support to the industrial and services sectors. Such a strategy can be expected to encourage the development and economic growth of a developing country.

Objective To collect the basic information about knowledge,attitude and cordilon regarding health risk behaviors such as unintentional injuries,smoking,drinking,addictive drug use,unhealthy daily dietary behaviors and physical activities of two secondary and high school students in Chaoyang District.Methods A questionnaires of health risk behaviors was used in 460 secondary and high school students in Chaoyang District. Results The health risk behaviors were common among the middle and high school students.In the survey,31.3%of students rode on the wrong side of the road in the past 30 days;17.4%crossed the street at ther own will;20.6%of them fight one or more times during the 12 months;27.1%of them had ever tried cigarette smoking(even one or two puffs);67.3%of them drank alcohol before;19.6%of them had gambling etpeiremces;7.3%had experiences of drug obnse;6.9%of the students considered themselves overweight; 28.3%of the students had ever thought depalting fteir familles;6.9%caotnaly did it;5.1%had sex exporences.The prevalence rates of smoking,alcohol drinking,addictive medicine abuse and sexual behaviors were signifiatily higher in male than in female(P0.05).Conclusions It is necessary to promote an effective,timely faused health education to reduce risk behaviors among secondary and hig school stnderts these two schools
Analysis on the Optical Coating Damage of Input Mirror of Middle Infrared 2 μm KTA Optical Parametric Oscillator

The optical coating damage of input mirror of middle infrared 2 μm KTA optical parametric oscillator is analyzed preliminarily,and the comparative experiments are performed to identify its cause.It shows that thermal effect induced by optical coating defect is the main reason for the low anti-damage threshold of input mirror coating.Meanwhile,it also shows that the main source of coating damage is remnant 1.06 μm laser in the resonant cavity caused by the mis-adjustment of cavity mirrors.These results are useful for improving the design of optical parametric oscillator system and increasing its output energy.

A 64×64 image energy harvesting configurable image sensor

This paper presents a configurable image sensor with energy harvesting capabilities. The image sensor's pixels can be configured as photo-sensors for image acquisition or as tiny solar cells for energy harvesting. The proposed configurable pixel design requires four pixels and uses a N-well/P-sub photodiode which is typically regarded as a parasitic diode for energy harvesting. A chip containing a 64×64 array of configurable pixels, read-out circuitry and biasing was designed and fabricated on a standard 0.5 μm CMOS process. The pixel size is 36 μm×40.8 μm with a fill factor of 42%. Test results are presented demonstrating the dual functionality of the image sensor. Measurements show that 55 nW can be harvested for an illuminance of 500 lux at the lens plane.
Systems of Particles and Rigid Bodies

This chapter is the culmination of the primer. To start, the linear momentum of a system of K particles and N rigid bodies is discussed. Similarly, the angular momenta and kinetic energy of such a system are developed. We then turn to the balance laws for such a system. The complete analysis of the resulting differential equations that these laws provide is usually beyond the scope of an undergraduate engineering dynamics course, and instead we focus on some particular results. These results involve using conservations of energy, angular momentum, and linear momentum. We then illustrate how one or more such conservations can be used to obtain solutions to some problems.
Health IT Maturity and Hospital Quality: Effects of PACS Automation and Integration Levels on U.S. Hospital Performance

This study analyzed the effect of PACS technology automation and integration maturity on hospital quality scores in U.S. hospitals (n = 2,256). We found cardiology PACS level of integration (CPLI) had a significant effect on hospital efficiency (p=0.000); while level of radiology PACS integration (RPLI) had a significant effect on patient experience and outcome scores (p
A test of Spence’s theory of incentive motivation

Two implications of Spence’s theory of incentive motivation were tested using four groups of rats and a runway apparatus. Groups One and Two had 51 and 9 direct feeding experiences, respectively, in the runway goal box, while Groups Three and Four had the same number of direct feedings in a dissimilar goal box. Following this training designed to condition Ig, all Ss had six rewarded trials in the runway terminating at the runway goal box. Hypothesis (1), that K is a function of the number of classical conditioning trials, was not substantiated. Some support was found for the second hypothesis, that K is greater when conditioning occurs in a goal box which is similar to the rest of the runway, since 5s in Groups One and Two had shorter latencies than 5s in Group Three and Four on the third day of testing. The inferior performance of the former groups on the initial test trial was attributed to the failure of Ss to discriminate the starting box from the goal box and attendant occurrence of responses which were incompatible with running. A proposed test of this hypothesis was suggested.
Cars and Schools and Heart Is in Canada: Divergent Communication Pathways of Immigrant Women

This chapter focuses on the different backgrounds, situations, and trajectories of the participants, which influenced their technological affordances and, subsequently, their ICT-based communicative practices. I show that the participants divided neatly into two groups that reflected their different patterned responses to the distance and separation of family migration. Two distinct groups emerge within the sample with social class as a major factor, those who would be considered highly skilled and those with low skills. Their family backgrounds produced in them different levels of capital—human, social, and cultural—which further affected their transnational ICT-based communication within their networks. Resultantly, the two groups bonded and bridged differently within their networks.
Linear programming formulation for non-stationary, finite-horizon Markov decision process models

Abstract Linear programming (LP) formulations are often employed to solve stationary, infinite-horizon Markov decision process (MDP) models. We present an LP approach to solving non-stationary, finite-horizon MDP models that can potentially overcome the computational challenges of standard MDP solution procedures. Specifically, we establish the existence of an LP formulation for risk-neutral MDP models whose states and transition probabilities are temporally heterogeneous. This formulation can be recast as an approximate linear programming formulation with significantly fewer decision variables.

The Brain-Stem Matrix of the Vestibulo-Ocular Reflex

This report shows how one may calculate the functional strengths of the anatomical connections between second-order neurons in the vestibular nuclei and the motoneurons of the extra-ocular muscles that subserve the vestibulo-ocular reflex in all three dimensions. To transform neural signals in the spatial coordinates of the canals to motor commands in the coordinates of the muscles, every canal pair must project to every muscle pair. The strengths of these projections may be calculated by geometrical considerations alone. In addition, the changes in the strengths of these connections may be calculated when the reflex plastically adapts to the chronic wearing of optical devices that dissociate head movement and the relative movement of the visual environment. These calculations do not say how these modifications are made but they at least tell numerically what must be done and a few interesting features of these modifications emerge.
