Compact Object Binary Mergers Driven By Cluster Tides: A New Channel for LIGO/Virgo Gravitational-wave Events
Authors: Hamilton Chris , Rafikov Roman R.
Published: August 2019

The detections of gravitational waves (GWs) produced in mergers of binary black holes (BHs) and neutron stars (NSs) by LIGO/Virgo have stimulated interest in the origin of the progenitor binaries. Dense stellar systems—globular and nuclear star clusters—are natural sites of compact object binary formation and evolution toward merger. Here we explore a new channel for the production of binary mergers in clusters, in which the tidal field of the cluster secularly drives the binary to high eccentricity (even in the absence of a central massive BH) until GW emission becomes important. We employ the recently developed secular theory of cluster tide-driven binary evolution to compute present day merger rates for BH–BH, NS–BH, and NS–NS binaries, varying cluster potential and central concentration of the binary population (but ignoring cluster evolution and stellar flybys for now). Unlike other mechanisms, this new dynamical channel can produce a significant number of mergers out to cluster-centric distances of several parsecs. For NS–NS binaries we find merger rates in the range of 0.01–0.07 Gpc−3 yr−1 from globular clusters and 0.1–0.2 Gpc−3 yr−1 from cusped nuclear clusters. For NS–BH and BH–BH binaries we find small merger rates from globular clusters, but a rate of 0.1–0.2 Gpc−3 yr−1 from cusped nuclear clusters, contributing to the observed LIGO/Virgo rate at the level of several percent. Therefore, cluster tide-driven mergers constitute a new channel that can be further explored with current and future GW detectors.
Influence of crate size, oviposition time, number of adults and cannibalism on the reproduction ofTenebrio molitor

Published: August 2019

In an industrialised mealworm farm it is important to maximise the production and to know the number of mealworms in each container as early as possible in a fast and reliable way. Two experiments were performed. The first experiment assessed the influence of the number of beetles, crate surface area and oviposition time on the number produced mealworms. A full factorial design was used with 11 beetle densities (between 2.3-300 mg beetles/cm2), 5 oviposition times (from 1-14 days) and 4 different crate sizes (between 250-2,000 cm2). In the second experiment, the influence of cannibalism on the number of produced mealworms was assessed via an alternative oviposition method that prohibited cannibalism. Multiple linear regression was used to model the results. The results indicate that the number of beetles, oviposition time and surface area could predict the number of produced mealworms well. An increase in one of the three parameters increased the number of produced mealworms without reaching an optimum. Furthermore, the number of beetles and the oviposition time can be combined in one parameter, beetledays with minimal loss of predictive power of the model. Nevertheless, the number of produced mealworms per female did decline rapidly with increasing oviposition time and density. The latter is, at least in part, due to cannibalism, as the second experiment indicates that the density effect is almost eliminated when the beetles are unable to reach their eggs. In conclusion, this study indicates that it is possible to construct a formula that can be used toa priori determine the final number of produced mealworms based on the number of beetles, surface area and oviposition time and that cannibalism can greatly reduce the number of produced mealworms. Reducing cannibalism can greatly increase the efficiency and therefore production of a mealworm farm.
Mobile Health Technologies to Deliver and Support Cognitive-Behavioral Therapy
Authors: Schueller Stephen M. , Adkins Elizabeth C.
Published: August 2019

Advances in technology are changing the ways cognitive-behavioral therapy (CBT) can be delivered. Through mobile technologies, effective interventions exist that allow people to receive CBT without ever visiting a practitioner's office. Additionally, mobile technologies are increasingly entering practitioners' offices, combining technological and human elements to create hybrid forms of care. Although clinical research has demonstrated exciting possibilities for mobile technologies to deliver and support CBT, for the most part clinical practice has been unchanged. We provide an overview of mobile CBT tools used either to deliver or to support CBT, highlighting what works and noting current limitations of our understanding. We also discuss new avenues in mobile CBT that leverage peers, artificial intelligence and chatbots, and mobile sensing to create scalable, personalized, and context-aware interventions. The future of mobile CBT should not be confined to digitizing current practices but should leverage technological affordances to improve CBT as it exists today.

Thomas Learmonth and Sons: Family capitalism, Scottish identity and the architecture of Victorian pastoralism
Authors: Edquist Harriet
Published: August 2019

This paper is concerned with the family as one of the key entrepreneurial and capitalist agents in the colonisation of Australia. Private enterprise has long been understood to be one of the prime factors in this history and Scottish families were particularly active. My case study is the Learmonth family who hailed from the Falkirk area in Stirlingshire, 44 km west of Edinburgh. Their story exemplifies the imbrication of family identity in its dynastic character with the opportunities afforded by the colonial expansion of the British empire and how this was figured in built works. Of significance for the paper is an understanding of what was at stake in Scotland for the Learmonth family and its lineage and how Thomas Learmonth, youngest of four sons, and his sons used colonial acquisitions to embellish their family status and identity at home. Ercildoun, the famous sheep station they established near Ballarat in Victoria was the final achievement of their Australian sojourn and it propelled them from the margins of Scottish life to somewhere much nearer its centre. The paper will show how they, as pastoralists and breeders of the “pure Australian merino” operated in the colonial enterprise-driven and global modality of economic migration that drove the expansion of the Port Phillip District of New South Wales in the 1830s and 1840s.
An English Country House in Calcutta: mapping networks between Government House, the statesman John Adam, and the architect Robert Adam
Authors: Ayers Sydney
Published: August 2019

Government House in Calcutta, today known as the Raj Bhavan of West Bengal, was built between 1799 and 1803 as the official residence for the Governor-General of Fort William, then the 1st Marquess Wellesley. It is well-established that Government House is modelled after Kedleston Hall in Derbyshire, England, known for the involvement of Robert Adam in its design. A significant fact linking Adam, and therefore Kedleston, with Government House is the previously unacknowledged presence of Adam’s great-nephew, the statesman John Adam, in Calcutta at the time Government House was designed and built. In the exploration of Scottish architectural and familial networks within the British empire, this article seeks to locate the identities of Robert Adam and John Adam within a series of exchanges: between Government House and Kedleston Hall; between public buildings and private houses; between India and Britain; and finally between Scottish, English and British identities. In the context of these exchanges, the study of Government House allows us to connect Robert Adam and John Adam, explore concealments of Scottish identity, and ultimately map previously unknown familial, professional and architectural networks.
Respect for Human Rights as a Predictor of Arab Spring Intensity
Authors: Hudson-Flege Matthew D
Published: August 2019

The popular uprisings of the Arab Spring have had a profound impact in the Arab World and beyond, and numerous researchers and commentators have explored the causes of these events. The present study sought to build upon an empirical exploration of political, economic, and social predictive factors of Arab Spring intensity by incorporating measures of countries' respect for human rights. Ordinal regression analyses found that countries' scores on the Cingranelli-Richards (CIRI) Physical Integrity Rights Index in 2010 significantly predicted levels of unrest experienced during the Arab Spring, such that countries who demonstrated less respect for physical integrity human rights experienced higher levels of unrest during the Arab Spring. The implications for future research and policy are discussed.

Published: August 2019

Social networking (SN) technology has been presented to human beings as a means of communicating, collaborating, connecting, and cooperating to exchange knowledge, skills, news, chat, and to maintain contact with peers world-wide. This article examines SN awareness in the Asia-Pacific (AP) education sector (ES) with a specific focus on the advantages and disadvantages of SN; and investigated whether AP culture influences SN adoption by the ES. An online survey was distributed to 1014 AP students and a total of 826 students responded. Several new advantages of adoption emerged from the data analysis. SN enabled students to accomplish their study tasks more quickly; it allowed them to communicate and collaborate with peers world-wide; and it fostered sustainability. The disadvantages perceived by students include depression, loneliness, and distraction, lack of interest in pursuing traditional activities, and security and privacy concerns. Finally, culture does influence SN adoption by ES institutions in AP countries.

Authors: Sun Bruce Qiang , Swan Tina Ting , Lu Yan , Mathien Lorena
Published: August 2019

Under the new measurement for the internet supplied from the Cooperative Association for Internet Data Analysis (CAIDA), the authors relax the orthogonal and normality condition with the methodology based on empirical codependence structures and marginal distributions. The nonparametric dependence between the diffusion of the internet and different globalization indices is examined using a panel of 10 countries, as long as error terms do not follow multivariate Gaussian distributions. The model selections are ranked and the authors find the best dependence model. The empirical dependence of the Internet diffusion on the globalization is further demonstrated from the dynamic copula analysis.

Authors: Gao Ge , Wang Tianyong , Zheng Xianrong , Chen Yong , Xu Xiaobo
Published: August 2019

The factors that affect formation and dissemination of public opinion have been studied for a long time. However, the findings are disparate and fragmented, given the characteristics of netizens and new media in the Big Data era. To this end, this article introduces eight mechanisms working on formation and dissemination of public opinion on network. Based on system dynamics, this article further proposes a comprehensive causal relationship model to explore the factors affecting the consequence of public opinion on network. Particularly, the role of government is taken into consideration in this model. A simulation with Vensim PLE is conducted. The results of the simulation indicate that group polarization among netizens, opinion leaders, the quantity of media audience, the frequency of media report, government attention, and warning mechanism for public opinion crisis affect the consequence of public opinion on network significantly. Implications of the findings are discussed.
Verification on Possibility of Nitrogen Diffusion into Steel by High Temperature N-Quench
Authors: Nakamura Atsushi , Nambu Koichiro , Okumiya Masahiro
Published: August 2019

N-Quench, which is a new surface heat treatment to infiltrate nitrogen into steel parts followed by quenching to achieve hardening, is gathering attention in the nitriding field as it affords low distortion while maintaining a higher effective case depth (ECD) compared with conventional nitriding. N-Quench is conducted mainly between 680°C and 800°C, where the two-phase region of ferrite and austenite exists in the Fe-N phase diagram. However, a few studies have reported on nitriding at temperatures higher than 800°C due to decomposition of NH3, which is a key source of nitrogen infiltration. Our results revealed that in a conventional furnace such as resistance heating furnace, no nitrogen infiltrated the specimen at 930°C, which is the general carburizing temperature. On the other hand, in the infrared heating furnace, nitrogen infiltrated the specimen at 930°C successfully with lesser NH3introduction than that required by the conventional furnace. Therefore, in this study, the limit of NH3decomposition is assessed and possibility of extending the applicability of N-Quench, especially increasing the ECD while maintaining a low distortion, is examined.
Design of Streamline Dies for Drawing Driven by Fracture
Authors: Alexandrov Sergei , Lyamina Elena , Date Prashant P.
Published: August 2019

This paper presents an efficient analytical method for design of streamline dies driven by fracture. The method is based on Bernoulli’s theorem relating pressure and velocity along any streamline extended to ideal flows in plasticity. The Cockroft-Latham criterion is adopted to predict the initiation of ductile fracture. In order to apply the method developed, it is not necessary to know the solution to the boundary value problem of plasticity. The final result is a simple relation between geometric parameters of the process and the constitutive parameter involved in the fracture criterion. Since the latter is supposed to be known for a given material, the relation determines a safe domain for drawing without fracture.

Published: August 2019

Blunt chest trauma with isolated or multiple rib fractures constitutes a common presentation in Emergency Department (ED), particularly in elderly people. Rib fractures in the elderly create short- and long-term disabilities with a dramatic impact. Pain management in the elderly could be problematic due to non-steroidal anti-inflammatory drugs (NSAIDs) contraindication or interaction with other drugs. We performed this retrospective study collecting and retrieving all patients aged 65 or older, with a diagnosis of rib(s) fracture(s) during an 18-month period. We analyzed the different treatments chosen, and divided them into subgroups: oxycodone- naloxone, and other treatments (also divided in: codeineacetaminophen; NSAID or Acetaminophen; Tramadol or Tapentadol). A total of 475 elderly patients (aged 65 and older) with single or multiple rib fractures were evaluated in our ED in 18 months: of these 410 patients were considered eligible, with a mean age of 79.28 years (standard deviation 7.83). 185 were male and 225 were female. Our study confirms the efficacy and tolerability of fixed association of oxycodone and naloxone. This association determined the highest and fastest reduction on Numeric Pain Scale reported by patients and is significantly better than other drugs in oral administration.
Measles in adults: A comparison of hospitalised HIV-infected and HIV-uninfected patients
Authors: Diana Nina E. , Feldman Charles
Published: August 2019

Background: Although measles is traditionally a childhood illness, there are an increasing number of adult cases. Despite both measles and HIV infection being endemic in sub-Saharan Africa, there are little data regarding outcomes in co-infected patients.Objectives: Compare demographic, clinical, laboratory and radiographic features, as well as outcome (length of hospital stay, complications and mortality) between HIV-infected and HIV-uninfected adult patients admitted with confirmed measles.Methods: We conducted a retrospective record review of adult patients with confirmed measles who were admitted to the Infectious Diseases Unit at the Charlotte Maxeke Johannesburg Academic Hospital during the peak of the 2009 and 2010 South African measles outbreak. The data collected included demographic, clinical and laboratory parameters, as well as outcomes.Results: Of the 33 confirmed measles cases admitted, 24 patients were tested for HIV infection and 18 tested seropositive. There were no significant differences in the demographics, clinical findings or laboratory data when comparing the HIV-positive and HIV-negative cases. Serious clinical manifestations were seen more frequently in HIV-positive patients (odds ratio [OR] 5, 95% confidence interval [CI] 0.48–51.8, p = 0.34). One of the six patients testing HIV-negative developed pneumonia, while six of the 18 HIV-positive patients had a course complicated by pneumonia. Five of these HIV-positive patients required admission to the intensive care unit, three developing respiratory failure necessitating mechanical ventilation. HIV-positive patients had several other manifestations, including acute kidney injury, purulent conjunctivitis, pancreatitis and encephalitis. HIV-positive patients had a significantly longer hospital stay (p = 0.03). There were three deaths in the HIV-positive group, but none in the HIV-negative group (OR 2.9, 95% CI 0.13–65.3, p = 0.55).Conclusion: Our study provides data on the largest series of hospitalised adults infected with HIV and co-infected with measles. More severe consequences seemed to occur in hospitalised HIV-positive patients.
Linear Independence of Logarithms of Cyclotomic Numbers and a Conjecture of Livingston
Authors: Chatterjee Tapas , Dhillon Sonika
Published: August 2019

In 1965, A. Livingston conjectured the $\overline{\mathbb{Q}}$-linear independence of logarithms of values of the sine function at rational arguments. In 2016, S. Pathak disproved the conjecture. In this article, we give a new proof of Livingston’s conjecture using some fundamental trigonometric identities. Moreover, we show that a stronger version of her theorem is true. In fact, we modify this conjecture by introducing a co-primality condition, and in that case we provide the necessary and sufficient conditions for the conjecture to be true. Finally, we identify a maximal linearly independent subset of the numbers considered in Livingston’s conjecture.

Published: August 2019

The objective of this study is to analyze the consolidation of a languages laboratory in the internationalization process of a Community Institution of Higher Education (CIHE) as a way to promote regional development. The CIHE in question has operated in the northwestern region of the Rio Grande do Sul state for sixty years, and it uses a languages laboratory (LELU) as part of its internationalization strategy. Data were obtained through an interview with LELU coordinator and through reports of the English teaching platform used by the CIHE, using SPSS, version 21 (Statistical Package for the Social Sciences) to perform descriptive statistical analyses and determine the frequency of the data collected in reports and documents from the languages laboratory as well as reports of the online English platform. The main results show the consolidation of LELU in the process of the CIHE internationalization operating on several fronts: distance learning in a virtual environment, classroom-based lessons and study groups in English, working consistently and continuously with students, professors and scholarship holders from different research projects.
Macroeconomic Policy Frameworks for Resource-Rich Developing Countries
Authors:   International Monetary Fund
Published: August 2019

This paper aims to widen the prism through which Fund policy analysis is conducted for resource-rich developing countries (RRDCs). While all resource-rich economies face resource revenue exhaustibility and volatility, RRDCs face additional challenges, including lack of access to international capital markets and domestic capital scarcity. Resource exhaustibility gives rise to inter-temporal decisions of how much of the resource wealth to consume and how much to save, and revenue volatility calls for appropriate fiscal rules and precautionary savings. Under certain conditions, it would be optimal for a significant share of a RRDC’s savings to be in domestic real assets (e.g., investment in domestic infrastructure), though absorptive capacity constraints need to be tackled to promote efficient spending and short-run policies are needed to preserve macroeconomic stability. The objective of this paper is to develop new macro-fiscal frameworks and policy analysis tools for RRDCs that could enhance Fund policy advice.
2011 Review of Conditionality - Content and Application of Conditionality
Authors:   International Monetary Fund
Published: August 2019

This paper reviews the design of conditionality in Fund-supported programs from 2002 to end-September 2011, with an emphasis on recent years. It focuses on the content and application of program conditionality—especially structural conditionality—in relation to the 2002 Conditionality Guidelines (the "Guidelines"), the Staff Statement on Principles Underlying the Guidelines on Conditionality, and subsequent revisions to operational guidance on conditionality. The analysis is based on the five key interrelated principles guiding the design of conditionality: national ownership of programs, parsimony in program-related conditions, tailoring to country circumstances, effective coordination with other multilateral institutions, and clarity in the specification of conditions. In particular, the principle of parsimony requires that program-related conditions be critical (or the minimum necessary) to achieve program objectives and goals, critical for monitoring program implementation, or necessary for implementing specific provisions under the Articles of Agreement (the "criticality criterion"). Beyond assessing compliance with these guidelines and principles, the paper also examines the implementation of conditionality

Published: August 2019

Enhancing public and private investment, but also ensuring that this translates into higher growth and employment, have long been key policy challenges in Arab countries. Reflecting an improvement in policies and global conditions, investment rates in Arab countries have increased over the past couple of decades. In spite of this—and notwithstanding significant differences across the region—investment has on average been somewhat weaker than in peer countries and less effective at generating growth. Private investment, particularly foreign direct investment (FDI), has underperformed significantly. And while public capital spending has benefited from high oil prices in resource–rich countries, it has continued to lag in oil importers...
An experimental study on light scattering matrices for Chinese loess
dust with different particle size distributions
Authors: Liu Jia , Zhang Qixing , Wang Jinjun , Zhang Yongming
Published: August 2019

Abstract. Mineral dust suspended in the atmosphere has significant effects on radiative balance and climate change. Chinese Loess Plateau (CLP) is generally considered as a main sources of Asian dust aerosol. After being lifted by wind, dust particles with various size distributions can be transported for different distances. In this study, original loess sample was collected from Luochuan, which is centrally located at CLP, and two samples with different size distributions were obtained after then. Pristine loess was used to represent dust that only affect source regions, part of pristine loess was milled to finer milled loess that can be transported for long distance. Light scattering matrices for these two samples were measured at 532 nm wavelength from 5° to 160° angles. Particle size distribution, refractive index, chemical component, and microscopic appearance were also measured for auxiliary analyses. Results showed that discrepancies in angular behaviours of matrix elements for pristine loess and milled loess cannot be ignored. Given that the effective radii of these two loess samples differ by more than 20 times, it is reasonable to conclude that the difference in size distributions plays a major role in leading to different matrices, while refractive index and micro structure have relatively small impacts. Analyses of numerical simulation results about irregular particles also variety this conclusion. At last, synthetic scattering matrices for both pristine loess and milled loess were calculated over 0°–180°, and the previous average scattering matrix for loess dust was updated.

Published: August 2019

Abstract. The study of the relationship between water storage and
runoff generation has long been a focus of the hydrological sciences. NASA's
Gravity Recovery and Climate Experiment (GRACE) mission provides monthly
depth-integrated information on terrestrial water storage anomalies derived
from time-variable gravity observations. As the first basin-scale storage
measurement technique, these data offer potentially novel insight into the
storage–discharge relationship. Here, we apply GRACE data in a streamflow
recession analysis with river discharge measurements across several
subdomains of the Mississippi River basin. Nonlinear regression analysis
was used for 12 watersheds to determine that the fraction of baseflow in
streams during non-winter months varies from 52 % to 75 % regionally.
Additionally, the first quantitative estimate of absolute drainable water
storage was estimated. For the 2002–2014 period, the drainable storage in
the Mississippi River basin ranged from 2900±400 to 3600±400 km3.

Published: August 2019

Existing polymeric cable sealing end (CSE) typically contain silicone oil as an insulating liquid between the cable core and the outside of the CSE. In recent years, a number of performance issues have been identified with silicone oil filled CSEs. To understand the reasons for the observed behavior of silicone oil, a range of characterization methods are reviewed, to allow investigation of the influence of moisture, potential chemical contaminants and the compatibility with CSE materials. The water content of all the oils studied was above the limit given in IEC 60836 (2015) for new silicone oil. There is no significant difference between the moisture content, whether the oil is used in CSE or new. Neither did the Fourier infrared (FTIR) spectroscopic analysis show difference between the oils. Preliminary results from gas chromatography connected to mass spectrometer (GC/MS) clearly show structural differences between unused expired oil and new oil samples particularly that species suspected to be cyclic siloxane appear to be present in the expired sample.

Published: August 2019

A systematic study of the influence of surface modification of nanosilica with coupling agents having different polarities on the dielectric properties of a PP/POE/silica blend was performed. The main goal of this investigation was to tailor the chemical composition of the silica surface, in order to modify the charge trapping properties of the nanocomposites. For the modification of the silica surface, a “green” approach was utilized: a dry silanization method, which is performed without the need of a solvent. The results of the thermogravimetric analysis (TGA) indicate that the dry process is an effective method to perform silica surface modification using alkoxysilanes.The charge trapping properties were studied by Thermally Stimulated Depolarization Current (TSDC) measurements. The obtained TSDC results show significant differences in charge trapping properties of PP/POE composites filled with differently modified silicas. Polar functional groups attached to the surface of the silica appear to have a strong effect on the charge trapping properties: The trap depth distribution becomes deeper and the trap density decreases to significantly lower levels.All results show that incorporation of surface modified nanosilica into a PP/POE matrix is a promising approach to tailor its dielectric properties. Further development of these composites may lead to benefits for application in high-voltage cable and capacitor applications.Keywords: silica surface modification, dry silanization, charge trapping, PP, POE, TSDC, high voltage cable.

As partof this differentiating/integrating (D/I) measuring concept, theuse of open-air sensors results in excellent EMC characteristicsbut the inherent cross-coupling to other phases has to be dealtwith. Three applications are presented: 1) For a 150 kV cabletermination the partial discharge activity needs to be related tomomentary phase voltages; 2) Measured slow front overvoltageat a 380 kV cable termination from line energizationare compared with predictions from numerical simulation; 3)The perspectives of employing the D/I method for (very) fastfront overvoltages near a 380 kV circuit breaker are examined.
Influence of Standard Lightning Impulse Front Time Tolerances on the Flashover Voltage of Suspension Insulators
Authors: Kluss J , Chalaki-Rostaghi M , Yousefpour K , Ahmed Z , Haque F
Published: August 2019

For high voltage impulse testing, a standard lightning impulse is defined in IEEE Std. 4 and IEC 60060-1 as a double exponential waveform having a front time T1 = 1.2 μs ± 30% and time to half-value T2 = 50 μs ± 20%. It has been noticed that for a given specimen, it is possible to successfully pass a flashover test at one end of the T1 tolerance range while failing the same test at the opposite end of the tolerance spectrum. Consequently, a systematic approach was adopted to investigate this observation. Up-and-down tests were performed to define the disruptive discharge voltage (critical flashover voltage CFO, U50) for 1, 5, 10, and 15 unit glass insulator strings standard lightning impulses using the minimum acceptance front time value (T1 ≈ 0.84 μs). Tests were repeated using the maximum tolerance value (T1 ≈ 1.56 μs) to investigate the degree of divergence in the flashover value. Particular attention is given to the steepness (voltage-time characteristics) of the applied impulse to consider if tolerance criteria amendment is merited in a future standard revision. As the steepness impact is more renowned in non-uniform geometries, field homogeneity as a function of string length is also incorporated into the analysis.

Time Development of Voltage Frequency Dependence of Partial Discharge Activity in Voids
Authors: Aakre Torstein Grav , Ildstad Erling , Hvidsten Sverre
Published: August 2019

Condition assessment of high voltage equipment based on partial discharge measurements is often performed after a voltage pre-conditioning period. The aim of this paper is to present results from experimental examinations of time variance of partial discharge activity and to propose physical explanations of the phenomena observed. Experiments were performed on laboratory made 3 mm thick discs of generator bar insulation, consisting of mica and glass fiber reinforced epoxy with a 0.5 mm thick cylindrical void surfaces of 10 mm in diameter. The effect of conducting and insulating void surfaces was examined using copper tape as upper and lower electrodes of the voids. All objects were tested by 12 one-minute long AC voltage frequency sweeps at frequencies from 50 Hz to 0.1 Hz distributed in time from start of the experiment, after initial one-hour constant 50 Hz voltage application and during object short-circuiting for 20 h. The main result shows that in case of insulating voids the apparent charges vanished after the one-hour constant 50 Hz voltage application. After a grounding period of 5 minutes, the charge magnitudes slowly increased with time until reaching steady state after about 4-8 hours. Test objects with conductive void surfaces showed such reduction in case of PD testing at 0.1 Hz only. At voltage frequencies above 10 Hz the measured PD magnitudes were found to be nearly constant, close to the expected high theoretical value. This indicate that PD by-products strongly affected the void resistivity and thereby affect the PD activity of insulating voids. These by-products are temporary and disappear with time.

Published: August 2019

Background: Stable angina patients have difficulty understanding the tradeoffs
between treatment alternatives. In this analysis, we assessed treatment planning
conversations for stable angina to determine whether inadequate health literacy acts as
a barrier to communication that may partially explain this difficulty.Methods: We
conducted a descriptive analysis of patient questionnaire data from the PCI Choice
Trial. The main outcomes were the responses to the Decisional Conflict Scale and the
proportion of correct responses to knowledge questions about stable angina. We also
conducted a qualitative analysis on recordings of patient-clinician discussions about
treatment planning. The recordings were coded with the OPTION12 instrument for shared
decision-making. Two analysts independently assessed the number and types of patient
questions and expressions of preferences.Results: Patient engagement did not differ by
health literacy level and was generally low for all patients with respect to OPTION12
scores and the number of questions related to clinical aspects of treatment. Patients
with inadequate health literacy had significantly higher decisional conflict. However,
the proportion of knowledge questions answered correctly did not differ significantly by
health literacy level.Conclusions: Patients with inadequate health literacy had greater
decisional conflict but no difference in knowledge compared to patients with adequate
health literacy. Inadequate health literacy may act as a barrier to communication, but
gaps were found in patient engagement and knowledge for patients of all health literacy
levels. The recorded patient-clinician encounters and the health literacy measure were
valuable resources for conducting research on care delivery.

A Tutoria (“Mentoring”) é considerada uma modalidade em que uma pessoa mais experiente, denominada tutor, acompanha de perto, orienta e estimula – a partir de sua experiência, conhecimento e comportamento – um jovem iniciante em sua jornada universitária. O objetivo foi caracterizar a percepção de estudantes do primeiro semestre do Curso de Fonoaudiologia sobre um Programa de Tutoria (“Mentoring”) e descrever seu funcionamento. Foi aplicado um questionário semi-estruturado construído para esta pesquisa aos alunos participantes do Programa. Os dados foram analisados quantitativamente para as questões fechadas com respostas dicotômicas (sim/não) e qualitativamente através da obtenção de categorias de ocorrência para as questões abertas. Participaram 22 estudantes no total, sendo 20 (91%) do sexo feminino e 2 (9%) do sexo masculino. O intervalo de idade foi de 18 anos a 25 anos. Para as questões fechadas, o nível de concordância foi de aproximadamente 95.5%. Quanto à experiência pessoal, identificamos que o Programa auxiliou no ingresso e adaptação à Universidade (08), no processo de ensino-aprendizagem (05), no funcionamento de ferramentas e webpages da Universidade (04), na resolução de problemas ou dúvidas (03) e acolhimento aos estudantes ingressantes (02). Foi um momento de troca de experiências, ideias, discussões e orientações acerca de diversos temas relacionados ao processo de ingresso e adaptação à Universidade. Os estudantes reconheceram igualmente que o Programa trouxe benefícios em âmbito pessoal, educacional e profissional, sugerindo que este deve ser mantido e aperfeiçoado ao longo dos anos.
Borderland Unionism: Latina Activism in Ybor City and Tampa, Florida, 1935–1937
Authors: McNamara Sarah
Published: August 2019

This article examines the intersections of gender, labor, and political organizing in Tampa and Ybor City, Florida from 1935 to 1937. By following the personal and professional evolution of labor leader Luisa Moreno in the US South, this article explores the reciprocal relationship between Latina tobacco workers and Moreno’s approach to labor unionism and political mobilization. While Moreno arrived in Tampa prepared to unite workers across ideological and physical barriers, what she encountered was a borderland, a space where multiple groups asserted ultimate authority over place and people. Although the laws and legislation of the US government applied to those living in the city, their regulation depended on the actions of people who lived in the region and independently competed for influence and power. As a result of ethnic and racial boundaries in the city (not only between Anglos and people of color, but also between Latina/o and African American communities), Moreno adapted her strategy of traditional class-based unionism to the realities of this borderland and adopted a Latina-centric approach to labor organizing that joined international radicalism and grassroots interests to challenge the control of de jure and de facto Jim Crow exclusions.
Transpacific Camptowns: Korean Women, US Army Bases, and Military Prostitution in America
Authors: Doolan Yuri W.
Published: August 2019

Military prostitution has been a staple of US–Korea relations since the 1940s, contained in the so-called camptown communities surrounding US military bases in South Korea. But during the 1970s, as the US military steadily reduced its troop presence in Asia, camptowns were thrown into a chaotic state. Facing tremendous social disorder and economic upheaval, establishments that depended upon GI patronage began sending their madams and sex workers to domestic military sites through brokered marriages with US servicemen. These women arrived in the US South, a region housing the vast majority of America’s military. Consequently, southern bases like Fort Bragg in Fayetteville (NC), Fort Campbell in Clarksville (TN), and Fort Hood in Killeen (TX) saw the proliferation of military prostitution, which took form in illicit massage businesses catering to the sexual needs of local troop populations. By the 1980s, the Korean American sex trade would spread from these southern military towns to elsewhere in the United States. Highlighting the transpacific circuits among camptowns in South Korea and military bases in the United States since 1945, this article develops a portrait of the US South as a transnational militarized terrain, the camptown as a transpacific phenomenon, and Korean immigrant community formation as deeply intertwined with the happenings of US militarism abroad. In doing so, it explains how the proliferation of illicit massage businesses witnessed by southern military communities in the 1970s was a transnational outgrowth of military prostitution encouraged by the US military in South Korea.
Nursing students serve and learn how to check, change, and control blood pressure in the local community
Authors: Musallam Eyad , Changet Amanda N
Published: August 2019

Background: High blood pressure is currently affecting 103 million people in the United States and is a major risk factor for cardiovascular disease, stroke, and heart failure. The American Heart Association (AHA) launched Check. Change. Control. Program (CCC program). The program is an evidence-based hypertension management program that utilizes blood pressure self-monitoring to empower patients/participants to take ownership of their cardiovascular health.Project: Following the Partnership Model for Service Learning, Miami University and The AHA propose implementing the “Serve and Learn How to Check, Change, and Control: A Community-Based Intervention to Improve Blood Pressure Control” to improve the BP of a diverse group of residents in Middletown and Hamilton cities in Ohio.Participants: Fifteen nursing students served as volunteer health mentors. Each nursing student recruited five community members over the age of 18 and checked their blood pressure two times every month for four months. 80 community membered were recruited and joined the project for four months.Results: At the end of the program, more than half of the participants (n = 41) had blood pressure improvement (decrease in systolic or/a diastolic). On third of Tier 1/ HYPERTENSION participants (n = 10) have moved from uncontrolled (> or = to 130/80) to controlled (< or = to 129/79) based on comparing the participants’ 1st blood pressure reading to their last.Conclusions: The extremely positive effects of this project are an eye-opening on the need of applying the program on a larger scale. To apply this program on a larger scale, partnerships with community organizations such as community health and wellness centers are needed. These partnerships will provide quality access to healthcare. The students will be able to meet participants where they are in their communities in a safe, vibrant, open and welcoming centers.
FLYGTNINGENS VILKÅR
Authors: Kulturstudier Redaktionssekretær
Published: August 2019

Med inspiration fra filosoffen Hannah Arendt vil jeg rette blikket mod flugten som et eksistentielt vilkår. I det perspektiv kan flugten opfattes som en indstiftende begivenhed, der igangsætter en kæde af handlinger og reaktioner i verden og ikke mindst hos det menneske, for hvem flugten konstituerer en ny virkelighed. Artiklens empiriske grundlag er en række etnografiske interviews og samtaler med flygtninge i forbindelse med feltarbejder i Libanon udført i perioden 2017-2019.
