Creators: name: Klimscha, Florian
Publisher: name: Edition Topoi
Year: 2017

description: Dieser Beitrag beschreibt die Veränderungen, die die Einführung der extraktiven Metallurgie in der südlichen Levante bewirkten. Dabei wird eine Langzeitperspektive eingenommen. Der Autor fasst aktuelle Perspektiven im Hinblick auf eine geänderte Chronologie zusammen, die auf kalibrierten Radiokarbondaten basiert. Damit können die Verbindungen zwischen technischer Innovation und sozialen Veränderungen neu bewertet werden. In diesem Zusammenhang werden Argumente für und gegen einen an Schivelbusch angelehnten Blick auf extraktive Kupfermetallurgie sowie auf eine Vielzahl sozialer Bereiche diskutiert, in denen Veränderungen festgestellt werden können.

description: Trimming is a common operation in CAD, and, in its simplest formulation, consists in removing superfluous parts from a geometric entity described via splines (a spline patch). After trimming the geometric description of the patch remains unchanged, but the underlying mesh is unfitted with the physical object. We discuss the main problems arising when solving elliptic PDEs on a trimmed domain. First we prove that, even when Dirichlet boundary conditions are weakly enforced using Nitsche’s method, the resulting method suffers lack of stability. Then, we develop novel stabilization techniques based on a modification of the variational formulation, which allow us to recover well-posedness and guarantee accuracy. Optimal a priori error estimates are proven, and numerical examples confirming the theoretical results are provided.

description: Der Beitrag behandelt die Einführung der Eisentechnologie im nördlichen Mitteleuropa und diskutiert zwei wesentliche Aspekte. Zum einen wird der Frage nachgegangen, in wie weit es heute schon möglich ist, den Verlauf des Einführungsprozesses zu rekonstruieren, und wie dieser ausgesehen haben könnte. Zum anderen wird der Einführungsprozess auf intendierte und nicht intendierte Folgen hin untersucht. Welche ‘Kollateral-Prozesse‘ begleiten die Einführung, inwieweit ermöglichen sie die Innovation, gehen Hand in Hand mit ihr oder werden durch die Innovation angestoßen und hervorgerufen?

description: Indoor humidity is a crucial factor affecting people's health and well-being. Wireless humidity sensing techniques are scalable and low-cost, making them a promising solution for measuring humidity in indoor environments without requiring additional devices. Such, machine learning (ML) assisted WiFi sensing is being envisioned as the key enabler for integrated sensing and communication (ISAC). However, the current WiFi-based sensing systems, such as WiHumidity, suffer from low accuracy. We propose an enhanced WiFi-based humidity detection framework to address this issue that utilizes innovative filtering and data processing techniques to exploit humidity-specific channel state information (CSI) signatures during RF sensing. These signals are then fed into ML algorithms for detecting different humidity levels. Specifically, our improved de-noising solution for the CSI captured by commodity hardware for WiFi sensing, combined with the k-th nearest neighbour ML algorithm and resolution tuning technique, helps improve humidity sensing accuracy. Our commercially available hardware-based experiments provide insights into achievable sensing resolution. Our empirical investigation shows that our enhanced framework can improve the accuracy of humidity sensing to 97%.

description: In der zweiten Hälfte des zweiten Jts. v. Chr. zeigen sich in vielen Gebieten Eurasiens nach einer langen Epoche mobiler Lebensweise wieder permanente Ansiedlungen. Zwischen dem Schwarzem Meer, dem Kaukasus und dessen Nachbargebirgen entstehen neue Siedlungstypen, die ganz oder teilweise aus Stein errichtet sind. Insbesondere im Kaukasus bildet sich eine neue Architekturtradition mit komplexen, multifunktionalen Häusern heraus. Die Steinarchitektur wurde möglicherweise nicht im Kaukasus entwickelt, doch lässt sich hier ein kreativer Umgang mit dem neuen Baustoff beobachten. Fast über ein Jahrtausend hinweg sind immer wieder Innovationsschübe fassbar, die einerseits technische Lösungen im Wohnbau abbilden und andererseits das Reagieren auf soziale Bedürfnisse, die mit den neuen Wohnformen entstanden.
Working Lives in an Age of Mechanical Reproduction: Uruk-Period Mesopotamia

description: Ein Aufsatz Walter Benjamins aus dem Jahr 1936 verschaffte dem Begriff der mechanischen Reproduktion zur Berühmtheit. Benjamin beschäftigte sich allerdings mit modernen Entwicklungen. Hier argumentiere ich, dass es schon in der Uruk-Zeit im 4. Jt. v.u.Z. in Südmesopotamien eine weit verbreitete Tendenz zu sich wiederholenden Arbeitsvorgängen und damit zu mechanischer Reproduktion festzustellen ist. Ich erörtere, wie Arbeit in der Uruk-Zeit verstanden wurde und strukturiert war, und wie Innovationen im Bereich der Arbeit selbst andere Lebenssphären beeinflusste. Meine Überlegungen schließen Herstellung und Verwendung von Keramik, Bauten und das Baumaterial Lehmziegel, aber auch anthropomorphe Bilder aus dauerhaftem Material und Textilien ein.

description: Obesity and asthma prevalence have both risen among children over the last several decades, and research efforts increasingly suggest that obesity is associated with asthma. Some, but not all, studies have shown that the effect of obesity on asthma is stronger among non-atopic individuals than among those with atopy. Systemic inflammation may be a factor in this relationship.

description: In der zweiten Hälfte des 18. Jahrhunderts BCE gab Yarim-Lim von Alalakh Anweisung, seinen Palast mit Wandmalereien zu schmücken. Statt innersyrischer oder ‘mesopotamischer‘ Tradition von al secco-Malerei auf dunklem Lehmputz zu folgen, entschied er sich für eine technische und ikonographische Innovation der Ägäis, einen hellen, glänzenden Kalkputz mit einer Greifendarstellung. In der Folge treten ähnliche Wandverzierungen in Palästen und Häusern in Syrien und darüber hinaus auf. Mein Beitrag analysiert, warum diese technische und soziale Innovationen in einer lokalen Lebenswelt erfolgreich war. Zweitens werfe ich einen genaueren Blick auf die Auswirkungen der Wandmalereien, indem ich auf die Verwendung und Bedeutung der ‘ägäisierenden‘ Motive in den folgenden Jahrhunderten eingehe und die Herstellung einer levantinischen ‘Aegeanness‘ in anderen Medien untersuche.

description: Die Grabungen in Wrocław-Widawa, Fdst. 17, haben sehr interessantes und umfangreiches keramisches Material geliefert, das in die jüngere vorrömische Eisenzeit (Stufen A1–A3)datiert. Die sog. Küchenkeramik besteht hauptsächlich aus Töpfen und Vorratsgefäßen, deren Oberfläche rau oder geraut ist. Manchmal kommt auch die Schlickrauung vor. Die sog. Tischkeramik vertreten sorgfältig ausgeführte, häufig geglättete Schüsseln, Schalen und Töpfe. Gemeinsam für alle Funktionsgruppen ist das Vorkommen von X-Henkeln und die Facettierung der Gefäßmündungen. Der Fundstoff zeigt zwar keine nennenswerten Unterschiede zu Materialien der Przeworsk-Kultur aus Schlesien, Masowien und Großpolen, spürbar sind aber auch Einflüsse der Latène- und der Jastorf-Kultur.

description: Die Fundstelle 3 in Lipianki liegt im Tal der unteren Weichsel in der Nähe von Kwidzyn. Während der großflächigen Rettungsgrabung im Jahr 2010 wurden insgesamt 1127 Gräber und Siedlungsbefunde von der jüngeren vorrömischen Eisen bis zur Völkerwanderungszeit registriert. Die Untersuchung der zahlreichen Gefäßscherben zeigt eindeutig, dass die Siedlung in der Stufe A2 der jüngeren vorrömischen Eisenzeit entstand. Bemerkenswert ist die Anwesenheit von keramischen Formen, die in der Przeworsk-Kultur beheimatet sind, was auf enge Verbindungen des Unterweichselgebietes zu dieser benachbarten Kulturzone verweist. Festzustellen ist dabei die Fortsetzung der ‚Oksywie‘-Stilistik bei der Keramik, die in die Übergangszeit zwischen der jüngeren vorrömischen Eisenzeit und der Römischen Kaiserzeit (A3/B1) datiert sowie bei einigen Gefäßen der Wielbark-Kultur.

title: Studies of orbital electron capture using proportional counters
Creators: name: Drever, R.W.P.
Publisher: name: University of Glasgow
Year: 1958

description: In the first chapter the theory of orbital electron capture is briefly summarised, and experimental data available on K/p+ ratios and L/K capture ratios are surveyed. The accuracy of many of the experimental results is poor, but it is pointed out that the development of proportional counter techniques for studying low energy radiations has made better measurements possible. These techniques are discussed in the following chapter, with particular emphasis on the use of gaseous sources. The material of this introductory section of the thesis is drawn mainly from the literature, though an appreciable part of the discussion on gas source counters is based on the writer's own experience. The next two chapters relate to the development of new proportional counter techniques, made with the aim of overcoming some of the limitations to the use of gas sources. An investigation into the operation of proportional counters at high temperatures, initiated by Dr. A. Moljk and carried out jointly by him and the writer is described; and the development of a multiwire proportional counter system with small wall effects is discussed, particularly in relation to the measurement of weak sources. The principle of the latter counting system was due to Dr. Moljk and the writer, following an initial suggestion by Dr. S.C. Curran, and the experimental work and its interpretation was shared equally by us. The detailed design of the counter and of the associated electronic equipment (described in an appendix) was due largely to the writer. The final three chapters, forming the main part of the thesis, deal with studies of electron capture carried out with the aid of gas source techniques. An investigation of the decay of Cl36 , leading to the discovery of a previously undetected K-capture branch, is described in Chapter 5. This work was done jointly with Dr. Moljk. Chapter 6 concerns a measurement of the K/β+ ratio in the decay of F18, which enables limits to be set on Pierz interference effects in Gamow-Teller interactions. This experiment was performed in collaboration with Dr. Moljk, assisted by Mr. J. Scobie; though the writer takes the main responsibility for the results and their interpretation. Chapter 7 deals with a study of L-capture in Ge71. The L/K capture ratio was measured by a new direct, method using a multiwire counting system; and the results obtained show that previous work suggesting serious disagreement with theory is not valid. The writer was entirely responsible for the original conception of this experiment, its performance, and the interpretation of the results.
MATHICSE Technical Report: An a posteriori error estimator for isogeometric analysis on trimmed geometries
Creators: name: Buffa, Annalisa
name: Chanon, Ondine
name: Vázquez, Rafael
Publisher: name: MATHICSE, Écublens
Year: 2022

description: Trimming consists of cutting away parts of a geometric domain, without reconstructing a global parametrization (meshing). It is a widely used operation in computer aided design, which generates meshes that are unfitted with the described physical object. This paper develops an adaptive mesh refinement strategy on trimmed geometries in the context of hierarchical B-spline based isogeometric analysis. A residual a posteriori estimator of the energy norm of the numerical approximation error is derived, in the context of Poisson equation. The reliability of the estimator is proven, and the effectivity index is shown to be independent from the number of hierarchical levels and from the way the trimmed boundaries cut the underlying mesh. In particular, it is thus independent from the size of the active part of the trimmed mesh elements. Numerical experiments are performed to validate the presented theory.
Parent Perceptions of Neighborhood Stressors Are Associated with General Health and Child Respiratory Health Among Low-Income, Urban Families

description: This cross-sectional study examines parents’ perceptions of their neighborhoods and general and respiratory health among low-income Chicago families. Asthma disproportionately affects non-white, urban, and low socioeconomic status (SES) populations, but Chicago’s burden, and the national epidemic, are not well-explained by known risk factors. Urban dwellers experience acute and chronic stressors that produce psychological distress and are hypothesized to impact health through biological and behavioral pathways. Identifying factors that covary with lower SES and minority-group status -- e.g. stress -- is important for understanding asthma’s social patterning.

description: Intense bombardment of solar system planets in the immediate aftermath of protoplanetary disk dissipation has played a key role in their atmospheric evolution. During this epoch, energetic collisions will have removed significant masses of gas from rocky planet atmospheres. Noble gases are powerful tracers of this early atmospheric history, xenon in particular, which on Mars and Earth shows significant depletions and isotopic fractionations relative to the lighter noble gasses. To evaluate the effect of impacts on the loss and fractionation of xenon, we measure its ionization and recombination efficiency by laser shock and apply these constraints to model impact-driven atmospheric escape on Mars. We demonstrate that impact bombardment within the first $200$ to $300\,\text{Myr}$ of solar system history generates the observed Xe depletion and isotope fractionation of the modern martian atmosphere. This process may also explain the Xe depletion recorded in Earth's deep mantle and provides a latest date for the timing of giant planet instability.

Establishment of Normative Data on Cognitive Tests for Comparison with Athletes Sustaining Mild Head Injury
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1998

description: OBJECTIVE: To provide normal data for comparison with objective measures of an athlete's cognitive ability after mild head injury (MHI).

SUBJECTS: Seventy-two Division I college athletes.

DESIGN AND SETTING: Athletes were assessed on three test dates (two days apart) in a sports medicine research laboratory.

MEASUREMENTS: Normative data were collected on four cognitive tests (Hopkins Verbal Learning Test, Stroop Test, Reitan Trail-Making Tests, and Wechsler Digit Span Tests).

RESULTS: A repeated-measures analysis of variance revealed significant learning effects on all tests except the Hopkins Verbal Learning Test. A high correlation was noted between the Stroop and the Trail-Making Tests.

CONCLUSIONS: These normative data can be used as comparisions to provide an objective measure of an athlete's cognitive ability following MHI. By adding this test battery to the athlete's other physical and neurologic tests, the decision to return an athlete to competition after MHI can be made with greater confidence and with less risk of reinjury.
title: Stormy weather: democratizing expertise in a changing climate: essays on environmental knowledge and social vulnerability in Mexico and India
Creators: name: Bridel, Anna
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: This set of essays expands knowledge about climate change governance by analysing how local people influence expertise about storms. This is motivated by the projected intensification of climate change and its disproportionate effects on marginalized people in the so-called Global South, together with the frequent irrelevance of expertise to those who depend upon it most, even when they are included in processes of knowledge production. The papers draw on debates from three literatures: the politics of expertise from Science and Technology Studies (STS); participation from Development Studies; and vulnerability from Disaster Risk Reduction (DRR). The main contribution of these papers is to expand what we mean by inclusion in knowledge production – that it is not merely the integration of diverse actors, but how political structures shape what knowledge gets heard and who is seen to be producing it – and apply it in conditions of climate risk governance. The papers describe research in four localities in Mexico and India where marginalized fishing communities are vulnerable to storms, and different configurations of risk, local vulnerabilities, and political cultures offer grounds for comparison. Ethnographic research methods including interviews and participant observation carried out in 2018, 2019 and 2020 were used to gather material which was subjected to discourse and content analysis. The papers argue that political orders, fisher identities and knowledges are interdependently constituted. The essays add to debates about the democratization of climate expertise by analysing the underexplored effect of expertise as a contested form of politics for climate change adaptation, thereby suggesting ways that development in the context of climate change can better reflect the needs of local 4 people. The papers contend that making climate policy more relevant and useful requires not just including vulnerable people but understanding how their capacity to shape expertise is embedded in contemporary politics.

description: To separate seismic interference (SI) noise while ensuring high signal fidelity, we propose a deep neural network (DNN)-based workflow applied to common shot gathers (CSGs). In our design, a small subset of the entire to-be-processed data set is first processed by a conventional algorithm to obtain an estimate of the SI noise (from now on called the SI noise model). By manually blending the SI noise model with SI-free CSGs and a set of simulated random noise, we obtain training inputs for the DNN. The SI-free CSGs can be either real SI-free CSGs from the survey or SI-attenuated CSGs produced in parallel with the SI noise model from the conventional algorithm depending on the specific project. To enhance the DNN's output signal fidelity, adjacent shots on both sides of the to-be-processed shot are used as additional channels of the input. We train the DNN to output the SI noise into one channel and the SI-free shot along with the intact random noise into another. Once trained, the DNN can be applied to the entire data set contaminated by the same types of SI in the training process, producing results efficiently. For demonstration, we applied the proposed DNN-based workflow to 3D seismic field data acquired from the Northern Viking Graben (NVG) of the North Sea, and compared it with a conventional algorithm. The studied area has a challenging SI contamination problem with no sail lines free from SI noise during the acquisition. The comparison shows that the proposed DNN-based workflow outperformed the conventional algorithm in processing quality with less noise residual and better signal preservation. This validates its feasibility and value for real processing projects.

Collegiate Coaches' Knowledge of Eating Disorders
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1999

description: OBJECTIVE: To assess, through exploratory research, 1) collegiate coaches' knowledge of eating disorders, 2) the confidence of collegiate coaches in their response correctness to questions about eating disorders among athletes, and 3) demographic data related to prior education about eating disorders and the role of the athletic department in providing such educational experiences.

DESIGN AND SETTING: We distributed a 2-part questionnaire to 258 NCAA Division I-A coaches from 5 universities selected by sampling convenience.

SUBJECTS: One hundred thirty-eight collegiate coaches responded to the questionnaire for a response rate of 53.5%.

MEASUREMENTS: Our survey consisted of 30 true-false questions that tested knowledge of eating disorders overall and in 5 domains. These domains included etiology, identifying signs and symptoms, management and treatment, risk factors, and education and prevention of eating disorders. Coaches indicated their level of certainty in their responses by rating their confidence level on a 4-item Likert-type scale. Demographic data focused on educational programs attended by coaches and teams. Descriptive statistics were used to analyze all data.

RESULTS: Our results suggest a need for coaches to achieve a greater knowledge of eating disorders in all domains. Evidence showed that educational programs about eating disorders were not often sponsored by the athletic department for coaches or athletes. There seemed to be poor communication between athletic departments and coaches regarding the availability of eating disorder educational resources.

CONCLUSIONS: Data suggested coaches could benefit from comprehensive education in all domains of eating disorders; however, further study is needed to validate these findings, to determine the actual effectiveness of education in the prevention of eating disorders, and to differentiate coaches' knowledge specific to sport coached and to coach and team sex.
Comparison of 3 Methods of External Support for Management of Acute Lateral Ankle Sprains

Year: 1999

description: OBJECTIVE: To examine the efficacy of 3 different types of injury support systems (standard elastic wrap with horseshoe, Aircast Sport Stirrup, and Omni Multiphase orthosis) used in treating acute inversion ankle sprains.

SUBJECTS: We recruited 30 physically active college-aged subjects who had sustained a grade 1 + or 2 lateral ankle sprain within the previous 24 hours for the study.

DESIGN AND SETTING: Subjects were randomly placed into one of 3 groups, the first treated with standard elastic wrap with horseshoe, the second with an Aircast Sport Stirrup, and the third with an Omni Multiphase orthosis. Subjects reported to the athletic training room on days 1, 2, 3, 5, and 7 postinjury.

MEASUREMENTS: We assessed subjects for ankle volume, functional performance, and self-perception of symptoms during the 5 postinjury assessments.

RESULTS: We found no significant differences among the 3 groups on measures of volume, level of function, and self-perception of symptoms.

CONCLUSIONS: Our results suggest that none of these methods is superior to the others for reducing swelling, restoring function, or relieving symptoms during the acute management of lateral ankle sprains.

Die Vergesellschaftung mit anderen Spätlatènefunden ist wichtig, um Keramik der Przeworsk-Kultur von ihren Nachklängen in der Großromstedter Kultur unterscheiden zu können. Spuren der Przeworsk-Kultur sind im nordöstlichen Baden-Württemberg zwar selten und teils unsicher, bei größeren Fundkomplexen aus archäologischen Grabungen ist jedoch durchaus mit klarer bestimmbaren weiteren Funden zu rechnen.

description: OBJECTIVE: To examine the effects of fatigue on proprioception and neuromuscular control of the shoulder.

DESIGN AND SETTING: Subjects were randomly assigned to either an experimental group or control group. Subjects were tested using either the active angle-reproduction or the single- arm dynamic stability test. The subjects were then fatigued using a dynamometer performing continuous, concentric rotation exercises of the shoulder. Once fatigued, the subjects were posttested using the same test. One week later, the subjects returned and were pretested, fatigued, and posttested using the other test.

SUBJECTS: Thirty-two college-age (18 to 25 years) subjects (16 males, 16 females) with no history of glenohumeral instability or upper extremity injury volunteered for this study.

MEASUREMENTS: Absolute angular error was measured using an electrogoniometer present within the isokinetic dynamometer, while sway velocity was measured using a force-plate system.

RESULTS: Repeated-measures analysis of variance revealed a significant difference between the pretest and posttest values for absolute angular error in the experimental group, whereas no significant difference was revealed between pretest and posttest sway velocity for either the control or experimental group.

CONCLUSIONS: Fatigue of the internal and external rotators of the shoulder decreased proprioception of the shoulder, while having no significant effect on neuromuscular control.

description: Klaudios Ptolemaios verfasste seine Geographie in Alexandria, einer Stadt, die zu den bedeutendsten wissenschaftlichen Zentren des römischen Reiches zählte. Sein Werk bietet nicht nur eine umfangreiche Beschreibung der bekannten Welt sondern auch einen Einblick die gelehrte Geographie und Kartographie des 2. Jahrhunderts unserer Zeit. Die wichtigste Innovation des Ptolemaios auf diesem Gebiet bestand in dem Gebrauch von geographischen Koordinaten, um Karten zu erstellen. Sein Katalog, der die Breiten und Längen von tausenden von Orten enthält, ist eine unserer wertvollsten Quellen zur antiken oikoumenē. Über die Quellen und Arbeitsmethoden, die Ptolemaios verwendet hat, um seine Geographie anzufertigen, wissen wir jedoch sehr wenig. Um die Genese seines Ortskatalogs nachzuvollziehen, wird im vorliegenden Buch Ptolemaios Beschreibung der iberischen Halbinsel unter zwei miteinander verknüpften Aspekten untersucht. Im Fokus stehen zum einen die Quellen und wissenschaftlichen Methoden des Ptolemaios, und zum anderen die Überlieferungsgeschichte seiner Geographie von deren Abfassung bis hin zur Entstehung der ältesten Handschriften.

description: Although seminaphtorhodafluor (SNARF) dyes are already widely used to measure pH in cells and at biofilms, their synthesis has low yield and results in an unspecific position of a carboxy-group. The separation of 5′- and 6′-carboxy-SNARF reveals a pKa difference of 0.15, calling into question pH measurements with the (commercially available) mixture. Here we replace the bulky external dicarboxyphenyl ring with a propionate group and evaluate the spectral properties of the new derivative. Proceeding to the ethyl-iodoacetamide, covalent linkage to cysteine protein sites is achieved efficiently as shown with a cyanobacterial phytochrome, extending the scarce application of SNARF in bio-labelling in the current literature. Application in fluorescence lifetime imaging is demonstrated both with the lifetime-based and ratiometric-yield method.

description: Magnetic field-induced electric polarization has been observed in trigonal non-centrosymmetric paramagnetic Pr3Ga5SiO14 langasite. We detected quadratic electric polarization along the a-axis in the basal ab plane for various magnetic-field orientations. Electric polarization along the c-axis is only evident starting from the fourth power of magnetic field, in accordance with the trigonal symmetry. The magnetic properties of Pr3Ga5SiO14 primarily stem from the local anisotropic magnetic moment of the two lowest Pr3+ singlets (quasi-doublet) in the crystal electric field. The random distribution of Ga/Si in the 2d positions leads to a local distortion of C2 symmetry and to a splitting distribution of the quasi-doublet. By considering the interactions of local moments among different Pr3+ positions within a phenomenological approach for the allowed magnetoelectric coupling, we derive the electric polarization in terms of symmetry-allowed combinations of local magnetic susceptibilities and field components. The magnetic field dependence of electric polarization in the basal plane, P_{a,b*}, is mainly determined by the accumulation of effective local susceptibilities, exhibiting similar behavior in low fields, while polarization along the c-axis, P_c, arises from the non-equivalence of local effective magnetic susceptibilities in different Pr3+ positions. Our findings suggest that the temperature dependencies of magnetic and magnetoelectric susceptibilities are highly sensitive to the distribution of the quasi-doublet splitting, which reflects the local symmetry breaking.
Syncope and Atypical Chest Pain in an Intercollegiate Wrestler: A Case Report

description: OBJECTIVE: To present the case of a 20-year-old collegiate wrestler who suffered from atypical chest pains and syncope after rigorous exercise, dehydration, and ingestion of a metabolic stimulant.

BACKGROUND: As a result of pressure to obtain a lower body weight for competition, wrestlers often pursue practices to lose a substantial amount of weight in a short period of time. These practices include rigorous exercise, starvation, dehydration, laxatives, diuretics, and over-the-counter stimulants. Our case involves an athlete who ingested a metabolic stimulant containing ma huang (ephedrine) and suffered from syncope and atypical chest pains during a bout of rigorous exercise and dehydration to lose weight for competition.

DIFFERENTIAL DIAGNOSIS: Hypertrophic cardiomyopathy, electrolyte imbalance, drug overdose, traumatic head injury, myocardial infarction, syncope.

TREATMENT: The emergency medical services transported the athlete to the emergency room, and he was hospitalized for 2 days. After discharge, the team physician counseled the athlete in the dangers of metabolic stimulants and excessive weight-loss techniques.

UNIQUENESS: This case is unique because it presents an athlete who ingested an over-the-counter stimulant to lose weight and suffered from syncope and atypical chest pains during a bout of rigorous exercise and dehydration.

CONCLUSIONS: Athletic trainers must understand not only the dangers of excessive weight loss, but also the dangers of using unregulated ephedrine-containing stimulants to aid in weight loss.
A Comparison of Sideline Versus Clinical Cognitive Test Performance in Collegiate Athletes

description: OBJECTIVE: To test whether performance on 5 cognitive tests administered in a controlled clinical environment differed compared with administration in an uncontrolled sideline environment. Additionally, we investigated the effect of testing environment order on the learning effect for each cognitive test.

DESIGN AND SETTING: Athletes were assessed on 2 test occasions (8 +/- 2 days apart), once in a sports medicine research laboratory and once on a lacrosse practice field site.

SUBJECTS: A total of 59 Division I collegiate student-athletes participated in this study.

MEASUREMENTS: Normative data were collected on 5 cognitive tests (Stroop Test, Trail-Making Test part A, Trail-Making Test part B, Wechsler Digit-Span Forward Test, and Digit-Span Backward Test).

RESULTS: An independent-samples t test for environment difference on test day 1 revealed no significant differences between tests performed in the controlled environment and those performed in the uncontrolled environment. A repeated- measures analysis of variance test revealed a significant learning effect for all 5 tests, as subjects tended to improve approximately 11 points on the Stroop Test, 3 seconds on the Trail-Making A Test, 7 seconds on the Trail-Making B Test, and 1 point each on the Wechsler Digit Span Forward and Backward Tests. A paired-samples t test using delta scores (first test minus second test), sorted by order of testing environment, revealed a significant difference for the Stroop Test, but not for the remaining cognitive tests.

CONCLUSIONS: There appears to be no difference in cognitive testing performance completed in a controlled clinical environment versus that performed in an uncontrolled sideline environment. This finding suggests that clinicians can administer cognitive tests to athletes with mild head injuries in uncontrolled sideline environments and expect valid results. Thus, clinicians can more thoroughly evaluate mildly head-injured athletes during the most crucial period after injury so that a safe return-to-play decision can be based on quantifiable, objective data.
The economics of board diversity

description: The past decade has seen an increasing interest in the issue of board gender diversity around the world. Accompanying this interest is a global debate over the justifications behind board gender diversity. This debate stems from conflicting results of previous studies that overemphasise the relationship between board gender diversity and accounting performance measures. It is also attributable to a lack of empirical evidence on moral justifications for board gender diversity, especially how board gender diversity affects gender issues in the workplace. Filling these gaps in the prior literature is, therefore, necessary to provide a better understanding, which may eventually help to clarify the debate on the merits of board gender diversity. This thesis aims to empirically examine the theorised benefits of board gender diversity from both an economic and a moral perspective. In particular, this thesis seeks to answer the question of whether a business case for board gender diversity exists from the perspective of market valuation. The thesis also investigates whether gender diversity of the board leads to fairer opportunities for all employees in the workplace. To address these issues, I conduct three research projects with the following objectives: (1) to comprehensively analyse the reaction of stock market investors to announcements of female director appointments and resignations; (2) to examine the relationship between gender diversity at board level and gender diversity at managerial and non-managerial levels of the workplace; and (3) to investigate the effect of board gender diversity on a firm’s commitment to workplace gender equality with respect to talent identification, promotions and training and development – as well as the resulting impact on employees’ productivity. My findings suggest that there are strong economic and moral justifications for board gender diversity. In particular, this thesis shows that board gender diversity does matter to stock market investors because they consistently react to female director appointments and resignations. I also show that board gender diversity can be justified from a moral perspective as it leads to diversity at lower workplace levels. Evidence also suggests that board gender diversity positively affects firms’ commitment to maintaining a gender-equitable working environment, which eventually results in higher productivity among employees. Overall, the results of this thesis contribute to understanding the benefits of diversifying boards’ gender composition amidst increasingly global interest. It also provides policy-setters with novel and convincing evidence on which to build gender-related regulations for business environments.
