Characteristics of Emergency Department Visits and Select Predictors of Hospitalization for Adults With Newly Diagnosed Cancer in a Safety-Net Health System
Authors: Hong Arthur S. , Sadeghi Navid , Harvey Valorie , Lee Simon Craddock , Halm Ethan A.
Published: April 2019

PURPOSE:

There is little description of emergency department (ED) visits and subsequent hospitalizations among a safety-net cancer population. We characterized patterns of ED visits and explored nonclinical predictors of subsequent hospitalization, including time of ED arrival.

PATIENTS AND METHODS:

This was a retrospective cohort study of patients with cancer (excluding leukemia and nonmelanoma skin cancer) between 2012 and 2016 at a large county urban safety-net health system. We identified ED visits occurring within 180 days after a cancer diagnosis, along with subsequent hospitalizations (observation stay or inpatient admission). We used mixed-effects multivariable logistic regression to model hospitalization at ED disposition, accounting for variability across patients and emergency physicians.

RESULTS:

The 9,050 adults with cancer were 77.2% nonwhite and 55.0% female. Nearly one-quarter (24.7%) of patients had advanced-stage cancer at diagnosis, and 9.7% died within 180 days of diagnosis. These patients accrued 11,282 ED visits within 180 days of diagnosis. Most patients had at least one ED visit (57.7%); half (49.9%) occurred during business hours (Monday through Friday, 8:00 am to 4:59 pm), and half (50.4%) resulted in hospitalization. More than half (57.5%) of ED visits were for complaints that included: pain/headache, nausea/vomiting/dehydration, fever, swelling, shortness of breath/cough, and medication refill. Patients were most often discharged home when they arrived between 8:00 am and 11:59 am (adjusted odds ratio for hospitalization, 0.69; 95% CI, 0.56 to 0.84).

CONCLUSION:

ED visits are common among safety-net patients with newly diagnosed cancer, and hospitalizations may be influenced by nonclinical factors. The majority of ED visits made by adults with newly diagnosed cancer in a safety-net health system could potentially be routed to an alternate site of care, such as a cancer urgent care clinic.
Delayed Puberty—Phenotypic Diversity, Molecular Genetic Mechanisms, and Recent Discoveries
Authors: Howard Sasha R , Dunkel Leo
Published: April 2019

This review presents a comprehensive discussion of the clinical condition of delayed puberty, a common presentation to the pediatric endocrinologist, which may present both diagnostic and prognostic challenges. Our understanding of the genetic control of pubertal timing has advanced thanks to active investigation in this field over the last two decades, but it remains in large part a fascinating and mysterious conundrum. The phenotype of delayed puberty is associated with adult health risks and common etiologies, and there is evidence for polygenic control of pubertal timing in the general population, sex-specificity, and epigenetic modulation. Moreover, much has been learned from comprehension of monogenic and digenic etiologies of pubertal delay and associated disorders and, in recent years, knowledge of oligogenic inheritance in conditions of GnRH deficiency. Recently there have been several novel discoveries in the field of self-limited delayed puberty, encompassing exciting developments linking this condition to both GnRH neuronal biology and metabolism and body mass. These data together highlight the fascinating heterogeneity of disorders underlying this phenotype and point to areas of future research where impactful developments can be made.

Published: April 2019

The chromodomain helicase DNA-binding 4 (CHD4), a member of the nucleosome remodeling and deacetylases (NuRD) complex, has been identified as an oncogene that modulates proliferation and migration of breast cancers (BC). ERBB2 is an oncogenic driver in 20-30% of BC in which its overexpression leads to increased chemoresistance. Here we investigated whether CHD4 depletion affects the ERBB2 cascade and autophagy, which represents a mechanism of resistance against Trastuzumab (Tz), a therapeutic anti-ERBB2 antibody.

We show that CHD4 depletion in two ERBB2+ BC cell lines strongly inhibits cell proliferation, induces p27KIP1 upregulation, Tyr1248 ERBB2 phosphorylation, ERK1/2 and AKT dephosphorylation, and downregulation of both ERBB2 and PI3K levels. Moreover, CHD4 silencing impairs late stages of autophagy, resulting in increased levels of LC3 II and SQSTM1/p62, lysosomal enlargement and accumulation of autolysosomes (ALs). Importantly, we show that CHD4 depletion and concomitant treatment with Tz prevent cell proliferation in vitro. Our results suggest that CHD4 plays a critical role in modulating cell proliferation, ERBB2 signaling cascade and autophagy and provide new insights on CHD4 as a potential target for the treatment of ERBB2+ BC.
Perceived reliability of assistance among American older adults: a study of kin and non-kin help
Authors: Gillespie Brian Joseph , Treas Judith
Published: April 2019

As a neglected dimension of the quality of care, assessments of caregiver reliability by older adults receiving help contributes to the better understanding of unmet needs for assistance in everyday life. This study examines how the numbers and composition of helpers – both potential and actual – relate to older Americans’ reports of the reliability of assistance. According to the 2008 US National Elder Mistreatment Study (n = 2,176), the potential network, proxied by marital status and household size, was not a significant predictor of unreliable care, nor was the actual number of caregivers. We distinguish four types of helping sources: kin-only; exclusively informal non-kin (eg friends, neighbours); exclusively formal (paid); and mixed type. There was a higher risk of unreliable care among respondents relying exclusively on informal non-kin assistance compared with exclusively kin help. Kin-only provided more reliable care than informal non-kin but were no more reliable than formal or mixed types.
Creative engagement with migration in Morocco: An ethnographic exploration of photographic encounters
Authors: Bachelet Sébastien , Jeffery Laura
Published: April 2019

This article examines the contentious topic of participation through the lens of a collaborative arts-based project on migration in Morocco. We call for the ethnographic exploration of photographic encounters: that is, participant observation of the processes of shooting, selecting, editing, preparing and exhibiting of photographs and films. First, we explore the need to identify barriers to participation and reflect on the role of researchers. Second, we stress how participatory arts-based workshops can confront Othering stereotypes amongst participants from diverse backgrounds. Third, we challenge social scientists’ tendency to prioritize process over product by considering public encounters as integral to participatory processes.

Shelled walnut (Juglans regia) kernels are prone to rancidity during storage. In this study we examined the preservation effect of cinnamon and clove essential oil (EO) vapors compared to cold storage and vacuum packaging by measuring the hexanal content, indicating rancidity, in stored walnut kernels. Odor and taste of stored shelled walnut was investigated by sensory evaluation and by measuring residues of the main EO components in the kernels. During storage under EO vapors, cinnamaldehyde and eugenol were absorbed on the surface of walnuts in a time-dependent manner changing the odor and taste of the kernels. Clove (Syzygium aromaticum) EO prevented rancidity and EO treated kernels were rated as acceptable by the sensory panel while cinnamon EO treatment increased rancidity compared to the other treatments and the control samples.
Parallelizing DSW Trees
Authors: Stanley Willard
Published: April 2019

A parallelization of the Day-Stout-Warren algorithm for balancing binary trees. As its input, this algorithm takes an arbitrary binary tree and returns an equivalent tree which is balanced so as to preserve the θ(log(n)) lookup time for elements of the tree. The sequential Day-Stout-Warren algorithm has a linear runtime and uses constant space. This new parallelization of the Day-Stout-Warren algorithm attempts to do the same while providing a speedup which is as near as possible to linear to the number of processing elements. Also, ideally it should do so in an online fashion, without blocking new reads, inserts, and deletes.
Parallelize DSW Algorithm

Published: April 2019

In this project, we propose a parallelized DSW algorithm, useful to periodically rebalance an arbitrary unbalanced BST. The proposed algorithm splits the tree into several subtrees and concurrently do ``Tree-to-Vine'' to these subtrees using multiple threads, and finally connects them into a complete vine; It also splits the vine into several semi-equal sized subvines and do ``Vine-to-Tree'' to these subvines using multiple threads, and combines them into a complete balanced tree. Our extensive experiments including BST generation, ``Tree-to-Vine'', and ``Vine-to-Tree'' parallelization comparisons show that this parallelized DSW algorithm performs much better compared to its counterpart sequential DSW algorithm.

Published: April 2019

Electronic and print resources usages and preferences among undergraduates of Landmark University, Omu-Aran, Kwara State, Nigeria has been examined. The study population consist of all undergraduates of the University, from which a sample of 250 that is 10 percent of the population was selected. The instrument used for data collection was a questionnaire. 231 copies of the questionnaire were completed and returned, representing 92.45 per cent response rate. Results from the study revealed that 110 (47.6 %) of the respondents preferred print resources, while interestingly, the same number 110 (47.6 %) preferred electronic resources; 11(4.8 %) of the participants did not provide any response to the question. It therefore implies that both print and electronic resources are complementary in meeting the information needs of undergraduates. However, majority of the respondents indicated that they usually supplement print materials with electronic resources or vice versa. The test of hypotheses revealed that user preferences were influenced by demographic factors such as age, course and level of study. Libraries should maintain hybrid collections, as both resources were found to be relevant sources of information for teaching, learning and research is recommended.
Plagiarism An Essay in Terminology
Authors: Satija MP , Martínez-Ávila Daniel
Published: April 2019

The terminology on plagiarism is not hard and fast. It is fluid, a bit ambiguous, and still emerging. It may take some time to settle the terms more clearly, concretely and exhaustively. This paper aims to provide a terminological discussion of some important and current concepts related to plagiarism. It discusses key terms/concepts such as copyright, citation cartels, citing vs. quoting, compulsive thief, cryptomnesia, data fakery, ignorance of laws and codes of ethics, information literacy, lack of training, misattribution, fair use clause, paraphrasing, plagiarism, plagiarism detection software, publish or perish syndrome, PubPeer, retraction, retraction vs. correction, retraction watch, salami publication, similarity score, Society for Scientific Values, and source attribution. The explanation and definition of these terms/concepts can be useful for LIS scholars and professionals in their efforts to fight plagiarism. We expect this terminology can be referred in future discussions on the topic and also used to improve the communications between the actors involved.
A cross sectional study of retraction notices of scholarly journals of science
Authors: Tripathi Manorama , Sonkar Sharad Kumar , Kumar Sunil
Published: April 2019

Retraction is the withdrawal of published article after it is found that the authors did not ensure integrity in conducting and reporting their research activities. The bibliometric information of 4716 document categorised as retractions in Science Citation Index, Web of Science was downloaded and analysed to understand trend, pattern and reasons of retraction. The results showed that retractions had increased during the ten-year period, 2008-2017. The main reasons for retractions were plagiarism, falsified data, manipulation of images and figures. It was also found that just 40 out of 4716 retraction notices had explicitly stated reasons for retracting the published articles. The open access journals had more number of retractions as compared to subscription based journals. The study will guide library professionals and research scholars towards a better comprehension of the reasons behind retractions in science discipline in the ten-year period. They would be better equipped to steer clear of inauthentic publications in their citations and references.
Approximate Solution and its Convergence Analysis for Hypersingular Integral Equations
Authors: Sharma Vaishali , Setia Amit
Published: April 2019

This paper propose a residual based Galerkin method with Legendre polynomial as a basis functions to find the approximate solution of hypersingular integral equations. These equations   occur quite naturally in the field of aeronautics  such as  problem of aerodynamics of flight vehicles  and during mathematical modeling  of  vortex  wakes  behind  aircraft.  The analytic solution of these kind of equations is known only for a particular case ( m(x,t) =0 in Eqn (1)).  Also,   in these  singular integral equations which occur during the formulation of many boundary value problems, the known function  m(x,t) in (Eqn (1)) is not always   zero.  Our proposed method find the approximate solution by converting the integral equations into a linear system of algebraic equations which is easy to solve. The convergence of sequence of approximate solutions is proved and error bound is obtained theoretically. The validation of derived theoretical results and implementation of method is also shown with the aid of numerical illustrations.
Strong approximation inh-mass of rectifiable currents under homological constraint

𝕄h⁢(T):=∫Mh⁢(θ)⁢𝑑ℋk.\mathbb{M}_{h}(T):=\int_{M}h(\theta)\,d\mathcal{H}^{k}.

Given such a rectifiable flat chainTwith𝕄h⁢(T)<∞{\mathbb{M}_{h}(T)<\infty}and∂⁡T{\partial T}polyhedral, we prove that for everyη>0{\eta>0}, it decomposes asT=P+∂⁡V{T=P+\partial V}withPpolyhedral,Vrectifiable,𝕄h⁢(V)<η{\mathbb{M}_{h}(V)<\eta}and𝕄h⁢(P)<𝕄h⁢(T)+η{\mathbb{M}_{h}(P)<\mathbb{M}_{h}(T)+\eta}. In short, we have a polyhedral chainPwhich strongly approximatesTinh-mass and preserves the homological constraint∂⁡P=∂⁡T{\partial P=\partial T}. Whenh′⁢(0+){h^{\prime}(0^{+})}is well defined and finite, the definition of theh-mass extends as a finite functional on the space of finite massk-chains (not necessarily rectifiable). We prove in this case a similar approximation result for finite massk-chains with polyhedral boundary. These results are motivated by the study of approximations of𝕄h{\mathbb{M}_{h}}by smoother functionals but they also provide explicit formulas for the lower semicontinuous envelope ofT↦𝕄h⁢(T)+𝕀∂⁡S⁢(∂⁡T){T\mapsto\mathbb{M}_{h}(T)+\mathbb{I}_{\partial S}(\partial T)}with respect to the topology of the flat norm.

Short-Run Health Consequences of Retirement and Pension Benefits: Evidence from China
Authors: Nikolov Plamen , Adelman Alan
Published: April 2019

This paper examines the impact of the New Rural Pension Scheme (NRPS) in China. Exploiting the staggered implementation of an NRPS policy expansion that began in 2009, we use a difference-in-difference approach to study the effects of the introduction of pension benefits on the health status, health behaviors, and healthcare utilization of rural Chinese adults age 60 and above. The results point to three main conclusions. First, in addition to improvements in self-reported health, older adults with access to the pension program experienced significant improvements in several important measures of health, including mobility, self-care, usual activities, and vision. Second, regarding the functional domains of mobility and self-care, we found that the females in the study group led in improvements over their male counterparts. Third, in our search for the mechanisms that drive positive retirement program results, we find evidence that changes in individual health behaviors, such as a reduction in drinking and smoking, and improved sleep habits, play an important role. Our findings point to the potential benefits of retirement programs resulting from social spillover effects. In addition, these programs may lessen the morbidity burden among the retired population.
Steam Reforming of Biomass Pyrolysis Oil: A Review
Authors: Adeniyi Adewale George , Otoikhian Kevin Shegun , Ighalo Joshua O.
Published: April 2019

The steam reforming of biomass pyrolysis oil is a well-established means of producing the more useful bio-hydrogen. Bio-oil has a comparatively low heating value, incomplete volatility and acidity, hence upgrading to a more useful product is required. Over the years, the experimental conditions of the process have been studied extensively in the domain of catalysis and process variable optimisation. Sorption enhancement is now being applied to the system to improve the purity of the hydrogen stream. Lifecycle analyses has revealed that bio-hydrogen offers considerable reductions in energy consumption compared to fossil fuel-derived hydrogen. Also, green-house-gas savings from the process can also be as high as 54.5 %. Unfortunately, techno-economic analyses have elucidated that bio-hydrogen production is still hampered by high production costs. Research endeavours in steam reforming of biomass bio-oil is done with an eye for developing added value products that can complement, substitute (and one day replace) fossil fuels whilst ameliorating the global warming menace.
Asymptotic orbital shadowing property for diffeomorphisms
Authors: Lee Manseob
Published: April 2019

Let M be a closed smooth Riemannian manifold and let f : M → M be a diffeomorphism. We show that if f has the C1 robustly asymptotic orbital shadowing property then it is an Anosov diffeomorphism. Moreover, for a C1 generic diffeomorphism f, if f has the asymptotic orbital shadowing property then it is a transitive Anosov diffeomorphism. In particular, we apply our results to volume-preserving diffeomorphisms.
Hopf bifurcation and the existence and stability of closed orbits in three-sector models of optimal endogenous growth
Authors: Nishimura Kazuo , Shigoka Tadashi
Published: April 2019

The present paper constructs a family of three-sector models of optimal endogenous growth, and conducts exact bifurcation analysis. In so doing, original six-dimensional equilibrium dynamics is decomposed into five-dimensional stationary autonomous dynamics and one-dimensional endogenously growing component. It is shown that the stationary dynamics thus decomposed undergoes supercritical Hopf bifurcation. It is inferred from the convex structure of our model that the dimension of a stable manifold of each closed orbit thus bifurcated in this five-dimensional dynamics should be two.
Bubble on real estate: the role of altruism and fiscal policy
Authors: Clain-Chamosset-Yvrard Lise , Seegmuller Thomas
Published: April 2019

In this paper, we are interested in the interplay between real estate bubble, aggregate capital accumulation and taxation in an overlapping generations economy with altruistic households. We consider a three-period overlapping generations model with three key elements: altruism, portfolio choice, and financial market imperfections. Households realise different investment decisions in terms of asset at different periods of life, face a binding borrowing constraint and leave bequests to their children. We show that altruism plays a key role on the existence of a productive real estate bubble, i.e. a bubble in real estate raising physical capital stock and aggregate output. The key mechanism relies on the fact that a real estate bubble raises income of retired households. Because of higher bequests, there children are able to invest more in productive capital. Introducing fiscal policy, we show that raising real estate taxation dampens capital accumulation.
Chaikovsky and the Economics of Art Music in Late Nineteenth-Century Russia
Authors: Bullock Philip Ross
Published: April 2019

As Russia’s first professional, conservatory-trained composer, Petr Il'ich Chaikovsky operated in the rapidly evolving social and economic context of post-emancipation Russia, identifying ways to interact with Russia’s musical institutions—its opera houses and theaters, its concert organizations and publishers—to fashion a career that was as successful financially as it was critically. Yet the myth of Chaikovsky’s financial incompetence persists, and the image, whether popular or scholarly, is still one of Chaikovsky as a spendthrift, unable to manage his income or regulate his outgoings. This article challenges such views by drawing on the recently published complete correspondence between Chaikovsky and his publisher, Petr Iurgenson, as well as on financial records preserved in the composer’s archives. In particular, this article analyzes the relationship among Chaikovsky, Iurgenson, and the operation of Russia’s musical “marketplace” at the level of genre, examining the interaction between financial considerations on the one hand and Chaikovsky’s decision to work in particular musical forms on the other. By examining the connections among Russia’s nascent musical institutions, Chaikovsky’s particular collaboration with his publisher, and the relative status of different musical genres, it becomes possible to establish the nature of Russia’s musical “art world” in the second half of the nineteenth century. In proposing a more nuanced and systematic account of Chaikovsky’s economic agency than has been attempted previously, this article thus contributes to a growing body of work on the institutional structures that shaped the Russian arts in the nineteenth century.
Systems biology: perspectives on multiscale modeling in research on endocrine-related cancers
Authors: Clarke Robert , Tyson John J , Tan Ming , Baumann William T , Jin Lu , Xuan Jianhua , Wang Yue
Published: April 2019

Drawing on concepts from experimental biology, computer science, informatics, mathematics and statistics, systems biologists integrate data across diverse platforms and scales of time and space to create computational and mathematical models of the integrative, holistic functions of living systems. Endocrine-related cancers are well suited to study from a systems perspective because of the signaling complexities arising from the roles of growth factors, hormones and their receptors as critical regulators of cancer cell biology and from the interactions among cancer cells, normal cells and signaling molecules in the tumor microenvironment. Moreover, growth factors, hormones and their receptors are often effective targets for therapeutic intervention, such as estrogen biosynthesis, estrogen receptors or HER2 in breast cancer and androgen receptors in prostate cancer. Given the complexity underlying the molecular control networks in these cancers, a simple, intuitive understanding of how endocrine-related cancers respond to therapeutic protocols has proved incomplete and unsatisfactory. Systems biology offers an alternative paradigm for understanding these cancers and their treatment. To correctly interpret the results of systems-based studies requires some knowledge of howin silicomodels are built, and how they are used to describe a system and to predict the effects of perturbations on system function. In this review, we provide a general perspective on the field of cancer systems biology, and we explore some of the advantages, limitations and pitfalls associated with using predictive multiscale modeling to study endocrine-related cancers.
Geodynamic Complexes and Structures of Transbaikalia: Record in Gravity Data
Authors: Dobretsov N.L. , Buslov M.M. , Vasilevsky A.N.
Published: April 2019

—The Transbaikalian region comprises several known geologic structures: the Mesozoic Mongolia-Okhotsk orogen, the Cenozoic Baikal rift system, and the world largest Angara–Vitim granitic batholith. They all formed upon heterogeneous Neoproterozoic– Early Paleozoic continental-margin complexes of the Siberian craton. The region is subject to the influence of mantle plumes, which induced Mesozoic–Cenozoic volcanism and controlled structural and lithological changes in the crust in the early history.

Transbaikalia, which has been a scene of multiple tectonic events, is a model area for geophysical (in particular, gravity) surveys for various geological and geodynamic applications. As a novel approach, we interpret geological and geodynamic data from the region with reference to the pattern of free-air and Bouguer gravity anomalies revealed by satellite altimetry. Bouguer anomalies highlight large structures in the lithospheric mantle which were produced in the Cenozoic mainly by the activity of mantle plumes. Basaltic lava fields were confirmed to be almost coeval with mantle anomalies and to record the presence of the plume head at the crustal base. However, the origin of the Late Paleozoic Angara–Vitim granitic batholith was only tentatively attributed to the plume activity, based on gravity data. Mesozoic metamorphic core complexes (MCC) and basins that formed during the evolution of the Mongolia–Okhotsk orogen show up clearly on the map of free-air anomalies. Most of the MCC revealed in Transbaikalia coincide with oval gravity highs and border negative elongate features corresponding to Mesozoic basins.

The zone of Cenozoic tectonism stands out in the pattern of free-air anomalies as maximum gravity contrasts, with the values changing from –110 to –120 mGal in basins to + 90 or +100 mGal in ranges. This zone encompasses rift basins filled with Cenozoic or, locally, Mesozoic sediments, which jointly form a domino-like system of rhomb-shaped structures typical of the Baikal rift system and, in general, of Cenozoic Central Asia resulted from the far-field effect of the India–Eurasia collision.

Published: April 2019

—Local site effect is a significant aspect of seismic hazards, which often causes amplification of ground motions and results in increase in the damage potential of an earthquake. This article displays an experimental study of microtremors data to investigate the dynamic characteristics of the soil and structures in the desert zone of Akhmim City, east of River Nile, Sohag governorate, Egypt. Because of progressive population growth in the Nile valley and delta regions, the Egyptian Governorate considered increasing the number of new communities, especially in the Sohag district, to improve the living conditions. The study area is one of the new urban areas which was suggested by Egyptian Urban Communities Authority (EUCA). For this purpose, the horizontal to vertical (H/V) spectral ratio was used to provide precious information about the soil properties and its engineering features for foundation purposes. The H/V spectral ratio analyses of ambient noise data at the measurement stations were processed and interpreted using Geopsy Software to calculate the amplification factor and fundamental resonance frequency at each observation point.

The results indicate that the resonance frequency ranges between 0.21 and 0.28 Hz at the most of the measurement stations, with some irregularities at stations No. 2 and 4 because of the higher softness of sediments in these locations. Most of lower fundamental frequencies are observed in the southern part of the study area, whereas higher values are observed in the northern part of the study area. The amplification factor ranges between 1.38 and 4.15. Higher values were recorded in the northeastern and southern parts, while lower ones were observed in the northwestern and southwestern parts of the mapped area. It can be concluded that the amplification component increases with increasing softness of the sediments. Interpretation of fundamental frequency distribution map is very significant to estimate the building heights and the number of stories, which was estimated to be 35 to 47.
Mixed Convective Transport Around Staggered Rows of Square Cylinders
Authors: Dipankar Chatterjee  , Bittagopal Mondal
Published: April 2019

The unsteady mixed convective transport around multiple bluff objects placed in a staggered configuration with respect to a uniform free stream flow is analyzed through two-dimensional numerical computation. The bluff objects are identical in shape and size with square cross-section and arranged in two different rows within an unconfined domain. A small temperature difference between the objects and the free stream results in the free convection in addition to the forced flow. Simulation is carried out using a finite volume based method considering a uniform cross flow of air (Prandtl number = 0.71) at a moderate Reynolds number (= 100). The transverse spacing between the cylinders may anticipated to influence significantly the wake dynamics, which in turn affects the thermal transport. Simultaneously, the mixed convective strength also influences the wake dynamics and vortex structure formation. An interplay between these two effects aptly dictates the resulting flow dynamics and associated thermal transport. Accordingly, the dimensionless transverse spacing is varied (= 1, 3 and 5) along with the mixed convective strength (Richardson number = 0-2). It is observed that the flow and thermal fields show chaotic nature at smaller transverse spacing. However, at larger spacing, the usual unsteady vortex dynamics persists. Very interestingly it is observed that the chaotic flow at smaller transverse spacing reduces its instability to become unsteady periodic at larger strength of the thermal buoyancy. The average heat transfer from the cylinders is found more at smaller transverse spacings and it increases with increasing mixed convective strength.
Structural Stability Assessment of a Masonry Chimney Subjected to Shocks by Vibration Measurements

Published: April 2019

Nowadays buildings can be stressed and shocked in different ways. Rail and road traffic, demolition work, machines, bells, wind and human movement itself can burden structures and disturb people. Not only a vibration prognosis, but also a monitoring during certain work is important to ensure buildings’ stability. A masonry chimney subject to shocks due to demolition works of surrounding halls was examined by using a new vibration measuring technique. This paper describes this new technique and its application during monitoring. For the measurement technique, the limit values of the German standard DIN 4150-3 were used and the events where this reference values exceeded, were examined in detail. A dynamic analysis of the structure, where the natural frequencies and their modal masses were determined, shows that the frequency-dependent reference values of the German standard DIN4150-3 for the protection of structures, include a relatively high safety factor. A possible exceeding of the values does not immediately lead to a loss of stability.

Salmonella is a major cause of morbidity and mortality in humans worldwide, and the infection with multidrug-resistant strains can cause severe diseases. This study was designed to evaluate the antimicrobial resistance, to detect the virulence genes, and to study the genetic diversity of isolated Salmonella strains using 16S rRNA sequences. For this, 34 Salmonella strains isolated from sausages were identified using biochemical and serological methods. Molecular tools were used to evaluate the presence of virulence genes (orgA, sitC, sipB, spiA, iroN, and sifA) using simplex and multiplex polymerase chain reaction (PCR) and to sequence 16S rRNA genes for phylogenetic analysis. The susceptibility to 24 selected antibiotics was also studied. The results of this study showed that all isolated Salmonella were positive for targeted virulence genes and were resistant to at least one antibiotic. However, the multidrug resistance was observed in 44% of isolated strains. The phylogenetic analysis of 16S rRNA sequences highlighted that Salmonella isolates were divided into 3 clusters and 3 sub-clusters, with a ≥98% similarity to Salmonella enterica species. From this study, we conclude that sausages are considered as a potential source of Salmonella, which could be a major risk to public health.
‘Straight-ish’
Authors: VanderStouwe Chris
Published: April 2019

Despite a robust literature on agency in language, gender, and sexuality research, constraints on agency as seen through multiple layers of identity, conflict, or construct are less clearly discussed. Through an analysis of straightidentified men seeking other men on a popular internet personal advertisement forum, I examine the language that individuals posting in men-seeking-men online personals employ to balance a self-presentation as a straight male while simultaneously seeking same-sex partners. To do so, I build upon current conceptualisations of agency to focus on the linguistic manipulation and negotiation of the constraints to their agentive abilities to construct identities and desires. These discursive negotiations serve to separate one's identity from one's desires in terms of space, time, and agency and create a nuanced understanding of these men's sexuality.
Postfeminism as a critical tool for gender and language study
Authors: Litosseliti Lia , Gill Rosalind , Favaro Laura
Published: April 2019

This article introduces the concept of postfeminism and highlights its value for research in language and gender studies. After discussing theoretical, historical and backlash perspectives, we advance an understanding of postfeminism as a sensibility - a patterned-yet-contradictory phenomenon intimately connected to neoliberalism. We consider elements widely theorised as constituting the postfeminist sensibility, alongside concerns shared by those who take postfeminism as their object of critical inquiry, in addition to an analytic category for cultural critique. The article then illustrates how the postfeminist sensibility may operate empirically, in the context of the doing and undoing of gender equality policies in workplaces. The article responds to calls for the field of language and gender to reinvigorate its political impetus, and to engage with feminist scholarship on postfeminism, particularly as recently developed in media and cultural studies.
‘Gendering’ the text through implicit citations of gendered discourses
Authors: Namatende-Sakwa Lydia
Published: April 2019

This study departs from the overriding focus on textbooks, which disregards how readers take them up. Informed by feminist post-structural theory, I analyse the construction of gender in children's fiction texts used in a New York City elementary school. First, I demonstrate that while the children's fiction texts were explicitly female dominated and/or progressive in their construction of gender, a feminist post-structural discourse reading illuminated that they in fact, implicitly cited discourses, which maintained gendered binary constructions and male dominance. Second, in going beyond the text, the study demonstrates that far from ignoring gender to focus on the 'official' curriculum as explicitly affirmed by the teachers, they had in fact implicitly and inadvertently cited, invoked and deployed discourses and discursive practices that inscribed gender differential and hierarchical relations in the use of the texts in the classroom. Third, I provide insights into teachers' lack of awareness regarding how gender is cited in their texts, and enacted in their teaching practices. I argue therefore that this 'talk around the text', which illuminated gendered discourses and practices, is, as well articulated by Jane Sunderland, 'an excellent epistemological site' for the deconstruction of traditionally gendered positions in the classroom.
