A Capacitive Micro-machined Ultrasonic Transducer (CMUT) with hexagonal membrane is constructed to work as a transmitter and compared to a CMUT with circular membrane. In this paper, three desirable combination of circular and hexagon are analyzed to select the dimensions for hexagonal shaped CMUT. Capacitive Micro-machined Ultrasonic Transducer (CMUT) is a micro constructed transducer used both as transmitter for generating ultrasonic waves and as receiver to modulate the electrical capacitance of the capacitive transducer. It can be fabricated with many geometries especially circular, square, rectangular, and hexagon. Circular CMUTs offers optimum performance in terms of deflection with DC, deflection of biased membrane with AC bias, resonant frequency, capacitance and deflection along frequency but for array formation the wafer area is wasted. A CMUT with hexagonal membrane gives an ultrasonic signal of constant amplitude with less deflection of membrane within the cavity and the outside environment. Stationary analysis is carried out with electro-mechanics for discussing the capacitance change of CMUT. The collapse or pull in voltage of hexagon CMUT is found to be high and increases the bandwidth of CMUT. The absolute percent difference of resonant frequency is observed to be 2.3 % with dimensions selected from the COH configuration of the CMUT.

This study is majorly concentrated on the various agricultural subsectors in Nigeria, how the subsectors has influenced the economic growth of Nigeria using econometric procedure to estimate the parameters of the model, and also the various shortcomings encountered by the agricultural subsectors in Nigeria and possible solutions. It also emphasize on the sector that has been abandoned, whereas, the growing recognition is directed toward the major resources (crude oil) which generated diminishing returns in agriculture contributions in regards to the economic growth in Nigeria. Moreover, the paper emphasized on the relationship of agricultural sub-sectors with Gross Domestic Product (GDP) which the sub-sectors entails crop production, fishery, livestock and forestry. The Intention of this research presents the conclusion that the agricultural part is a concrete sector of the economy and cannot be underrated or trivialized seeing that agricultural sector output is important to economic activities in Nigeria. Therefore, the general growth of the country’s economy depends on the progress of agriculture. If there’s availability of credit facility to the agricultural sector, it will enhance the boosting of the country’s GDP and thereby causing growth in the economy. An additional objective of this paper attempts to carry maximum value for public officials and legislators.

Cloud Computing is a paradigm of distributed computing that delivers on-demand and utility-based services to its customers. It provides a set of shared computing resources such as networking, servers, storage, and applications in the form of services to an organization or an individual. The major benefits of cloud computing include on-demand self-service and cost-effectiveness. For the customer, there is no up-front cost for setting up and running the applications on the cloud. Despite the benefits provided by various cloud services, the outsourcing of data storage and computation raise many new security issues. One of such security issues that have to be addressed before uploading our sensitive data to the cloud is data privacy. With the cloud model, end-users lose control over the physical location of data, because data will be stored and processed elsewhere on the globe and not in the local computer. Hence, we need an algorithm for encrypting the data that can be stored and retrieved from a database managed by the public cloud.

In persevering courteousness, CFD codes got developed and run with water based TiO2, AlN and CuO nanofluids to envision the thermal alarms of ICs. The convective governing equalities of mass, force and drive are computed for envisaging the thermal issues of ICs. The time pace selected throughout the intact computation is 0.0001 s. The soundings affect CFD forecasts of temperature curve, temperature arena plus fluid-solid boundary temperature of IC. Corresponding fluid-solid boundaries temperatures of IC are viewed as 351, 312 and 338 K for water based TiO2, AlN and CuO nanofluids, respectively. The temperature of water-AlN nanofluid stands peak contiguous to the IC locality as it stands far less than the chancy temperature limit of 356 K. Further, the temperature of water-AlN nanofluid gently drops with improvement in aloofness from IC. Afterwards, this becomes surrounding temperature in the distant arena precinct. The analogous tinted temperature curve stands accessible. In addition, the congruent plot of temperature verses distance from IC stays publicized. The apprehension of CFD lenient stand adjacent to the facilities of expressions.

Copra Crushing Industry has one of the production processes that is being used widely in the Oil production and manufacturing industries. Considering a fully equipped plant, the production ranges from 500-560 tons of oil per month. A good yielding copra provides 95% of output that has 5-7% of moisture content. Lesser the moisture content higher the yield. In the process of oil extraction, the copra is fed into the chute that is pumped onto the main silo for steaming process. This feeding process is done manually; hence, there are many mishaps occurring like copra falling away from the chute. A dried copra is crunchy enough to pierce the leg of the employees. Therefore, our paper aims to provide solution to these issues and ensure the safety of the employees. Design and fabrication of copra sweeping robot is proposed in this paper. The robot runs on wheels utilizes a sweeper mechanism to accumulate dried copra in a coconut oil extraction plant. This application of mechatronics comes under the field of Mobile Robotics. It is used to sweep the copra to one side so that the employees could pass through the place without any harm. It is provided with an attachment for the sweeping process. This could ultimately ensure employee safety and increase the productivity.
Gender, Agency and Vulnerability: The Case of Western Muslim Women Joining the ISIS
Authors: Raza AAmer
Published: August 2019

In this article I look at the case of Western Muslim women who joined the Islamic terrorist group of ISIS. I deconstruct the generally held assumptions in the main stream Western media about the desirability of an unrestricted life. One of the major questions that I raise through this article is whether or not feminist scholarship should aim at developing a certain standard of emancipation of women. To be more specific, through this study, I want to understand what freedom means for different actors—Western Muslim women, mainstream media, and social media—involved in the debate on young western men and women joining the ISIS.
Resisting Necro-biographies
Authors: Shapiro Michael
Published: August 2019

In order to determine whether an individual or a specific identity-bearing group has potential for terrorism, the state engages in a systematic practice of constructing biographies, which could warrant its use of lethal power. This practice privileges a security consciousness while discounting the vagaries of everyday life contingency, which plays a crucial role in creating who we are and what we do. The element of contingency becomes more visible when we focus on the lives of migrants and their movements. The State’s excessive concern with security inhibits the opportunity spaces for role exits from the indemnity economies it invents. In this brief response to such actions of the state, I take an ethical stance that affords victims the right to refute their constructed identities and to presenting counter-biographies.
Uneven Humanitarianism: Abandoned Refugees along the Thai-Myanmar Border
Authors: Sebro Tani
Published: August 2019

This essay considers the case of uneven humanitarian aid distribution along the Thai-Myanmar border, where forcibly displaced migrants from Myanmar have been abandoned by the UNHCR and international humanitarian organizations. Based upon long-term ethnographic fieldwork along the Thai-Myanmar border amongst Tai migrants from the Shan State in Myanmar, I attend to the effects of the inequitable distribution of rights and privileges in an international humanitarian system that is predicated on the neoliberal logic of uneven development. After two centuries of British colonial occupation and later Burman authoritarian rule, the ethnic minority groups along the Thai-Myanmar border are now facing another crisis – that of abandonment as NGOs search for new and more pressing humanitarian disasters elsewhere. The essay addresses a concept I call uneven humanitarianism as a neocolonial condition for peoples living in the Thai-Myanmar borderlands by specifically focusing on Tai peoples who are living in unofficial refugee camps that lost foreign funding in 2017. I argue that the ad hoc treatment and eventual abandonment of these vulnerable groups – that are currently in the midst of the world’s most protracted civil war and displacement situation – constitutes a failure of the “responsibility to protect” humanitarian project.
Zainab’s Murder: Heinous Crimes, Speedy Trial and the Challenge of Procedural Rights
Authors: Chughtai Ali
Published: August 2019

In early 2018, a seven-year old girl, Zainab Amin, was raped and murdered in district Kasur, Punjab province, Pakistan. The cold-blooded incident shocked the people across the country. These questions included the suspect’s confession before trial, the in-camera trial being completed within four consecutive working days, the cross-examination of 56 witnesses, and the paucity of time given to the defence counsel. In this paper I argue that although such heinous offences should be awarded legally warranted punishment, the courts must ensure that the special criminal procedure does not let go the principle of due process. I take Zainab’s case as an example to see whether the principle of due process and procedural rights of the suspect were ensured as required for a fair trial. The paper puts to critical light the chronological facts of the case (as reported in the press) and relies on applied jurisprudence to underscore the potential/danger of letting go the due process and procedural rights in speedy trials.
The death of Jamal Kashoggi: Issues of Human Rights Violations and International Law
Authors: Adegbonmire Jumoke
Published: August 2019

State responsibility is a cardinal principle of international law. The doctrine of State sovereignty under international law accords States’ legal personality and requires that they fulfill international obligations. International law imposes obligations on States to perform their duties in ensuring that a breach of international law does not go unpunished. Consequences for such actions means that States need to adhere to procedural and substantive law in addition to offering reparation for the violation of an international obligation. In the past, violation of an international obligation was only attributed to States as they were considered to be the only entity that could possess rights and duties within the international sphere. Therefore States were considered to be the only ones that could be criminally liable for acts that could be attributed to them. But the development in human rights law and the advent of rules governing personal criminal responsibility has extended the scope of international obligations under international law to include States and individuals as being liable for international crimes. The international law disallows immunity from prosecution in foreign domestic courts for the most serious crimes: Re-Pinochet case. This means State responsibility and individual responsibility for wrongful acts are not mutually exclusive.

Role of B-Mode ultrasound in the evaluation of orbital masses.
Authors: Kamlakar Kale Sushilkumar , Dhok Atul Manohar
Published: August 2019

Introduction: Blindness and Vision impairment cause significant morbidity amongst Indian population. According to WHO estimates, about 20.5
% people in India are categorized as blind while 22.2 % people have low vision. The orbital masses owing to the small anatomical volume of orbit
can cause devastating consequences. Ultrasound and colour doppler are useful in analysis of orbital masses with real time evaluation, excellent soft
tissue resolution, localisation, and benign or malignant nature of masses. This study evaluates the role of ultrasound in orbital masses.
Aim: To study the role of ultrasound in evaluation and identification of orbital masses.
Study design & settings: Prospective observational study in ultrasound unit of a rural hospital in central India.
Materials and methods: A total of 316 consenting patients were studied for 1 year using high frequency linear and curved probes. Statistical
analysis was done using SPSS software (IBM Inc.)
Results: Out of the 316 patients, total 15 cases were identified to have orbital masses. Most common orbital mass lesions observed were lacrimal
gland tumours. Most of the masses were extraconal in location and most common ultrasound appearance of the lesions was solid with most of the
malignant masses showing vascularity on colour doppler imaging.
Conclusion: Ultrasound can identify and characterize orbital masses based on appearance and echotexture with accurate localisation. It is cheap
and easily available with no radiation hazards Pre-operative ultrasound and Colour Doppler evaluation of orbit can help in predicting prognosis of
the disease

Silicocarbonatitic melt inclusions in fluorapatite from the Yates prospect, Otter Lake, Québec: Evidence of marble anatexis in the central metasedimentary belt of the Grenville Province
Authors: Schumann Dirk , Martin Robert F. , Fuchs Sebastian , de Fourestier Jeffrey
Published: August 2019

We have investigated a locality very well known to mineral collectors, the Yates U-Th prospect near Otter Lake, Québec. There, dikes of orange to pink calcite enclose euhedral prisms of fluorapatite, locally aligned. Early investigators pointed out the importance of micro-inclusions in the prisms. We describe and image the micro-inclusions in two polished sections of fluorapatite prisms, one of them with a millimetric globule of orange calcite similar to that in the matrix. We interpret the globule to have been an inclusion of melt trapped during growth. Micro-globules disseminated in the fluorapatite are interpreted to have crystallized in situ from aliquots of the boundary-layer melt enriched in constituents rejected by the fluorapatite; the micro-globules contain a complex jigsawed assemblage of carbonate, silicate, and sulfate minerals. Early minerals to crystallize are commonly partly dissolved and partly replaced by lower-temperature phases. Such jigsawed assemblages seem to be absent in the carbonate matrix sampled away from the fluorapatite prisms. The pressure and temperature attained at the Rigolet stage of the Grenville collisional orogeny were conducive to the anatexis of marble in the presence of H2O. The carbonate melt is considered to have become silicocarbonatitic by assimilation of the enclosing gneisses, which were also close to their melting point. Degassing was important, and the melt froze quickly. The evidence points to a magmatic origin for the carbonate dikes and the associated clinopyroxenite, rather than a skarn-related association.
High-resolution Transmission Spectroscopy of Four Hot Inflated Gas Giant Exoplanets
Authors: Žák Jiří , Kabáth Petr , Boffin Henri M. J. , Ivanov Valentin D. , Skarka Marek
Published: August 2019

The technique of transmission spectroscopy allows us to constrain the chemical composition of the atmospheres of transiting exoplanets. It relies on very high signal-to-noise spectroscopic (or spectrophotometric) observations and is thus most suited for bright exoplanet host stars. In the era of theTransiting Exoplanet Survey Satellite, Next Generation Space Telescope, and PLAnetary Transits and Oscillations of stars (PLATO), more and more suitable targets, even for mid-sized telescopes, are discovered. Furthermore, a wealth of archival data is available that could become a basis for long-term monitoring of exo-atmospheres. We analyzed archival High Accuracy Radial velocity Planet Searcher (HARPS) spectroscopic time series of four host stars to transiting bloated gas exoplanets, namely WASP-76b, WASP-127b, WASP-166b, and KELT-11b, searching for traces of sodium (sodium doublet), hydrogen (Hα, Hβ), and lithium (670.8 nm). The archival data sets include spectroscopic time series taken during transits. Comparing in- and out-of-transit spectra we can filter out the stellar lines and investigate the absorption from the planet. Simultaneously, the stellar activity is monitored using the Mgiand Cailines. We detect sodium in the atmosphere of WASP-76b at a 7–9σlevel. Furthermore, we report also at a 4–8σlevel of significance the detection of sodium in the atmosphere of WASP-127b, confirming earlier results based on low-resolution spectroscopy. The data show no sodium nor any other atom at high confidence levels for WASP-166b nor KELT-11b, hinting at the presence of thick high clouds.
The Probability Distribution of Density Fluctuations in Supersonic Turbulence
Authors: Pan Liubin , Padoan Paolo , Nordlund Åke
Published: August 2019

A theoretical formulation is developed for the probability distribution function (pdf) of gas density in supersonic turbulence at steady state, connecting it to the conditional statistics of the velocity divergence. Two sets of numerical simulations are carried out, using either a Riemann solver to evolve the Euler equations or a finite-difference method to evolve the Navier–Stokes (N-S) equations. After confirming the validity of our theoretical formulation with the N-S simulations, we examine the effects of dynamical processes on the pdf, showing that the nonlinear term in the divergence equation amplifies the right pdf tail and reduces the left one, the pressure term reduces both the right and left tails, and the viscosity term, counterintuitively, broadens the right tail of the pdf. Despite the inaccuracy of the velocity divergence from the Riemann runs, we show that the density pdf from the Riemann runs is consistent with that from the N-S runs. Taking advantage of their higher effective resolution, we use Riemann runs with resolution up to 20483 to study the dependence of the pdf on the Mach number,

, up to

. The pdf width, σ

s
, follows the relation

, with b ≈ 0.38. However, the pdf exhibits a negative skewness that increases with increasing

, as the growth of the right tail with increasing

tends to saturate. Thus, the usual prescription that combines a lognormal shape with a variance–Mach number relation greatly overestimates the right pdf tail at large

, with important consequences for star formation models.
New Nearby Hypervelocity Stars and Their Spatial Distribution from Gaia DR2

Published: August 2019

Based on about 4500 large tangential velocity (V
tan > 0.75V
esc) with high-precision proper motions and 5σ parallaxes in Gaia data release 2 (DR2) 5D information derived from parallax and proper motion, we identify more than 600 high-velocity stars with a 50% unbound probability. Of these, 28 nearby (less than 6 kpc) late-type hypervelocity stars (HVSs) with over a 99% possibility of being unbound are discovered. In order to search for the unbound stars from the full Gaia DR2 6D phase space information derived from the parallax, proper motion, and radial velocity, we also identify 28 stars from the total velocity (V
gc > 0.75V
esc) that have probabilities greater than 50% of being unbound from the Galaxy. Of these, only three have a nearly 99% probability of being unbound. In the whole HVSs subsample, there is 12 sources reported by other surveys. We study the spatial distribution of angular positions and angular separation of HVSs. We find the unbound HVSs are spatially anisotropic, which is most significant in the Galactic longitude at more than a 3σ level, and lower unbound probability HVSs are systematically more isotropic. The spatial distribution can reflect the origin of HVSs and we discuss the possible origin link with the anisotropy.

Published: August 2019

Sanghuangporus toxicodendri (Hymenochaetales) is described as new based on collections made from Shennongjia Forestry District, Hubei Province, China. All studied basidiocarps grew on living trunks of Toxicodendron sp. This new species is characterized by having perennial, effused-reflexed to pileate basidiocarps; pore surface brownish yellow or yellowish brown, pores 7–9 per mm; context 1–5 mm thick or almost invisible; setae ventricose, dark brown, 26–42 × 7–10 μm; basidia 4-sterigmate or occasionally 2-sterigmate; basidiospores broadly ellipsoid, smooth, brownish yellow, slightly thick-walled, mostly 3.5–4 × 2.8–3 μm. Maximum likelihood and Bayesian inference phylogenies inferred from internal transcribed spacer (ITS) region of rDNA indicated that Sanghuangporus spp. formed a monophyletic clade and resolved as a sister to Tropicoporus spp., and six strains of S. toxicodendri formed a monophyletic group which is sister to S. quercicola. An identification key to known species of Sanghuangporus is provided.

Représentation des chemins de Saint-Jacques par les marcheurs-pèlerins : l’expression d’une mythologie ?
Authors: Alcantara Christophe
Published: August 2019

Cet article propose d’interroger la perception des chemins de Saint-Jacques par les marcheurs-pèlerins, en prenant appui sur leur vécu du chemin jusqu’à Compostelle et l’interrogation de leur représentation du chemin. À travers une mythologie à l’œuvre au sens sémiologique, l’auteur a réalisé une étude qualitative fine grâce à une production du « dire sur le faire » de six renseignants qui va souligner les déformations et autres écarts dans la réflexivité des marcheurs-pèlerins. Les chemins de Saint-Jacques sont riches de signes, de rites, de pratiques que les marcheurs-pèlerins s’approprient au moins partiellement, et la signification à l’œuvre dans l’analyse de leur témoignage recouvre des réalités qui s’éloignent des postures affichées initialement.

À l’intérieur des grandes étapes de la chaîne de production d’un film de fiction, les différentes phases qui consistent pour le monteur son à recueillir les intentions de réalisation, bien que déterminantes pour l’ensemble de ses processus décisionnels, sont généralement décrites comme épineuses. En effet, nombre de monteurs disent devoir composer avec des metteurs en scène qui éprouvent parfois toutes les difficultés à communiquer leurs directives. Dans cet article, il s’agira de comprendre les facteurs qui peuvent concourir à de telles difficultés avant d’envisager comment ces dernières parviennent, selon les cas, à être contournées.
La « brève de consommation » : sémiotique d'un genre journalistique entre information et promotion
Authors: Desnica Mirta
Published: August 2019

Cet article a pour objet un genre de la presse écrite caractérisé par le fait de coupler l'information pour la consommation avec l'incitation à la consommation, et que l'auteure propose d'appeler « brève de consommation ». Ses propriétés sémiotiques et pragmatiques sont décrites à partir d'un corpus de presse féminine, dont ce genre textuel est emblématique. Il est ensuite étudié au regard des normes d'écriture journalistique telles qu'elles sont formulées dans les manuels de journalisme. Participant à la promotion de produits et de marques, ces articles apparaissent comme un lieu de rencontre entre le discours d'information journalistique et le discours marchand et comme un effet du « journalisme de marché ».
Les figures d'autorité dans la publicité testimoniale
Authors: Petters Lorreine
Published: August 2019

En contexte publicitaire, les figures d'autorité restituent parfois des vécus présumés en attestant de la vérité de leurs paroles. On associera une telle mise en scène à la notion de « publicité testimoniale ». Cet article s'interroge sur la définition même de la « publicité testimoniale », tout en s'intéressant aux individus capables d'y faire autorité et à leur prise de parole dans le cadre des messages testimoniaux. En identifiant trois figures d'autorité principales – la célébrité, la « personnalité d'entreprise » et la « personnalité du web » –, l'objectif est de comprendre la manière dont ces figures stimulent l'adhésion des interlocuteurs aux messages diffusés.
Blogs d'écrivain et écrivains-blogueurs : Internet et l'hybridation de la littérature
Authors: Ruiz Ugo
Published: August 2019

Cet article s'intéresse aux reconfigurations du domaine littéraire sur Internet. Entre ce qu'il propose d'appeler le « régime éditorial traditionnel » et le « nouveau régime éditorial », l'auteur établit une distinction qui est mise en perspective par l'étude des blogs de trois écrivains reconnus. Cette pratique littéraire du blog d'écrivain semble symptomatique d'un phénomène que l'auteur propose de désigner par le terme d'hybridation, en ce qu'il provient de la coexistence des deux régimes éditoriaux en tension. Au-delà du statut des écrivains-blogueurs, cette hybridation littéraire est la manifestation d'un changement plus radical qui engage une réflexion sur le pouvoir de la littérature et sur la notion d'autorité.
Le design de l'information : textualisation, documentarisation, auctorialisation
Authors: Zacklad Manuel
Published: August 2019

Dans cet article consacré au design de l'information, l'auteur propose une définition de l'information ancrée dans une vision anthropologique de la communication et présente l'approche ternaire de l'information de M. Buckland qui est en phase avec sa typologie. Dans un deuxième temps, un retour sur la notion de dispositif permet d'introduire les dispositifs d'information et de communication et d'en donner quelques exemples. Cette articulation permet, dans une troisième partie, d'aborder le design de l'information consignée dans toute sa richesse et sa complexité, combinant les problématiques de la textualisation, de l'auctorialisation et de la documentarisation.
L'agir documentaire, une politique du détail. À partir du cas de #SoyonsHumains
Authors: Bonaccorsi Julia
Published: August 2019

Le document est‑il une pratique politique et à quelles conditions peut‑il servir une critique sociale ? Cet article croise deux entrées sur le projet documentaire, comme processus et comme poétique. L'exploration sémio-discursive de la campagne de documentation photographique des « mobiliers urbains anti-SDF » initiée en décembre 2017 par la Fondation Abbé Pierre et Emmaüs Solidarité à partir du hashtag #SoyonsHumains permet de nourrir empiriquement la réflexion et de rendre compte du sens social du document dans la mise en discours et en visibilité de la « cause de l'autre ».
Le document dans une pragmatique sociale de l'information
Authors: Lehmans Anne , Liquète Vincent
Published: August 2019

En quoi l'analyse des pratiques sociales et professionnelles d'information peut‑elle enrichir les définitions du document telles qu'elles sont posées par les sciences de l'information et de la communication et renouveler leur approche  ? À partir de plusieurs contextes d'observation dans le cadre de projets de recherche, la classe, des espaces professionnels, l'atelier, on constate que les attentes sociales et l'activité font du document un espace co-construit, structurant l'organisation de l'information et sa gestion. Le document, en tant qu'espace dialogique, devient alors un moyen de formalisation des activités en jeu au regard des positionnements, des représentations et des finalités projetées. Sur la base de ces recherches, il est permis d'envisager un complément aux définitions actuelles du document, qui ne se focalise pas seulement sur son contenu mais sur les modalités de son élaboration et sur son rôle dans la construction des apprentissages.
Vieillir, cette affreuse chose. Les autoportraits de Roman Opalka et Maria Lassnig
Authors: Beyaert-Geslin Anne
Published: August 2019

Comme l'a indiqué naguère Locke, les signes et les images nous sont indispensables pour mémoriser et partager les expériences. En mettant en discours ce qui resterait sans eux, insaisissables, ils accomplissent la part positive d'une médiation. C'est ainsi qu'ils saisissent le temps au passage et le mettent en discours. L'article compare les autoportraits photographiques de Roman Opalka et les autoportraits peints par Maria Lassnig avec une méthodologie sémiotique pour comprendre comment, en faisant signifier des traces, ils relèvent à la fois le défi de la représentation du vieillissement et le partage de son expérience. Ceci permet de préciser les contributions du médium à cet « effet de temps » et de définir deux formes de vie contraires.

Atrial Fibrillation: Community Screening Events Improve Awareness in Older Adults
Authors: McCabe Pamela J. , Lloyd Margaret (Peg) A. , Balls-Berry Joyce , Johnson Jaclynn , LaScotte Jaimee , Lee Hon-Chi
Published: August 2019

Educating older adults during atrial fibrillation (AF) screening events to recognize signs and symptoms and seek evaluation may promote detection of AF that occurs between screenings. The authors evaluated learning outcomes of AF awareness education provided during AF screening using a single-arm, pre/posttest design. Participants completed the Knowledge, Attitudes, Beliefs about Atrial Fibrillation Self-Monitoring and Treatment-Seeking (KABAF-SMTS) survey, participated in AF awareness education, and completed a KABAF-SMTS survey 2 weeks after education. Paired
t
tests revealed that knowledge of AF symptoms increased (
p
= 0.007). Scores for recognizing the seriousness of AF (
p
= 0.003), benefits of self-monitoring (
p
< 0.001), perception of barriers to self-monitoring (
p
= 0.002), and confidence (
p
< 0.001) to recognize AF and seek treatment improved. AF awareness education strengthened knowledge, beliefs, and attitudes that may be conducive to recognition and treatment-seeking for AF. [

Vietnamese American Dementia Caregivers' Perceptions and Experiences of a Culturally Tailored, Evidence-Based Program to Reduce Stress and Depression
Authors: Ta Park Van M. , Ton Vy , Yeo Gwen , Tiet Quyen Q. , Vuong Quyen , Gallagher-Thompson Dolores
Published: August 2019

Vietnamese American dementia caregivers are at increased risk for adverse mental health compared to the general U.S. population given their sociodemographic and immigration experiences, yet programs that address their needs are lacking. The current article describes Vietnamese American dementia caregivers' perceptions and experiences of a culturally tailored, evidence-based intervention to reduce stress and depression. A convenience sample of caregivers was recruited from the San Francisco Bay area and randomly assigned to intervention (“Our Family Journey”; OFJ) (
n
= 30) or control (written dementia caregiving information) (
n
= 30) groups. All intervention and 76.7% of control caregivers reported that the OFJ or educational materials, respectively, were very/somewhat helpful. Three or more skills were refined/learned by 96.7% of OFJ and 36.6% of control participants. Qualitative findings indicated that the intervention had positive effects on well-being and taught new caregiving skills. This first U.S. study to address the mental health needs of Vietnamese American dementia caregivers shows positive perceptions/experiences and demonstrates a model to address a significant need in the community.

Processen van place-making door talige praktijken in Tilburg, Heerlen en Genk
Authors: Cornips Leonie , Marzo Stefania , Swanenberg Jos
Published: August 2019

Samenvatting

In dit artikel tonen we aan de hand van kwalitatieve data aan hoe talige praktijken met sprekers en artiesten uit drie steden in de periferie van Nederland en België, namelijk Tilburg, Heerlen en Genk een lokale identiteit construeren en reproduceren en hoe op die manier het besef van lokale eigenheid tot stand komt. We laten zien dat in deze drie steden artiesten en sprekers aan de hand van geënsceneerde en gemediatiseerde taalprakijken bewust nieuwe lokale identiteiten construeren. In de drie gevallen gaat het om hybride of heterogene taalprakijken, waarbij het Nederlands of lokale dialectale elementen gecombineerd worden met elementen uit andere aanwezige (contact)talen (zoals het Surinaams of het Italiaans). Bovendien worden deze taalpraktijken in Tilburg en Heerlen, maar ook – hoewel in mindere mate – voor Genk, via parodie verspreid, versterkt en vernieuwd.
