Published: February 2019

In this study we redescribe an ostracod species belonging to the subfamily Cypridopsinae Kaufmann, 1900, sampled in seven localities of northern and southern Patagonia, Argentina. A new taxonomical combination is proposed, Cypridopsis silvestrii comb. nov., based on detailed description of females and the first descriptions of males. Cypridopsis silvestrii occurred on a wide geographical distribution range, from 40º to 48º S latitude, as well as broad environmental tolerance ranges. We evaluated morphological variations in two populations of C. silvestrii from northern (El Toro lake) and southern (El Sello lake) Patagonia, with contrasting limnological conditions. El Toro is a small shallow lake with high salinity waters and El Sello is a large deep lake with lower salinity. Based on morphometric analysis, our results showed intraspecific variation in valve shape and size between populations. Sexual dimorphism in El Toro population was identified through morphometric analyses. Additionally, comparison of valve outlines in living and subfossil individuals from El Toro lake allowed specimens previously described as juveniles of Eucypris fontana (Graf, 1931) to be identified as adults of C. silvestrii comb. nov. The present contribution increases knowledge of the taxonomic identity, the ecological requirements and the geographical distribution of C. silvestrii, and shows that morphometric analyses are a feasible and useful tool for exploring intraspecific shape differences and assisting in taxonomic identification. Furthermore, the results presented herein provide tools for C. silvestrii identification in paleolimnological studies, and emphasize the usefulness of studying living representatives for clarification of the taxonomic status of species widely distributed in Quaternary sediments.
Update to the knowledge of the social wasps of the Brazilian state of Amapá based on the vespid collection of the Amapá Research Institute (IEPA) (Hymenoptera, Vespidae, Polistinae)
Authors: SILVEIRA ORLANDO TOBIAS , FURTADO NERCY VIRGINIA RABELO , GAMA JOSÉ MADSON DE FREITAS , DE SEIXAS FELIZARDO SHERLEM PATRICIA , DOS SANTOS IAN PATRICK VILHENA
Published: February 2019

Information is presented concerning specimen records of polistine social wasps in the state of Amapá, Brazil, in the years from 1904 to 2016, mainly coming from the IEPA and MPEG collections. Spatial distribution of records and of the total collecting effort were analyzed with respect to general landscape aspects of the region, such as vegetation types, hydrography, road infrastructure and the state network of conservation unities. The number of social wasp species registered for Amapá is now 144, with 17 new records of species for the Guiana Shield, and nine species not yet described. Seventeen genera are known to occur in the region, with Mischocyttarus de Saussure and Polybia Lepeletier being richer in species.
The Intelligentsia and the Holocaust: Dispersing the Image
Authors: Chmielewska Katarzyna
Published: February 2019

This paper in the field of cultural memory studies addresses the workings of memory, or more precisely – a politics of memory whereby the image of the intelligentsia and its role in the Holocaust vanishes from the collective consciousness. The relative visibility of peasants denouncing Jews, murdering them and plundering their property is accompanied by an invisibility of the intelligentsia and its essential role in reinforcing the exclusion and antisemitic patterns of behavior before the Holocaust which facilitated direct involvement in these events, as well as an invisibility of the intelligentsia’s own participation in the events of the Holocaust.
National Landscape with Lenin in the Background: Imagined National Communities in the Former Eastern Bloc
Authors: Stańczyk Xawery
Published: February 2019

The paper is a critical review of two recently published monographs on the subject of the everyday and banal forms of nationalism in the post-socialist countries of Europe and Asia. The authors of the monographs, drawing on the theories of national identity and nationhood by Benedict Anderson, Ernest Gellner, Eric Hobsbawm, Michael Billig, Michael Skey, Tim Edensor and others, showed their deep understanding of the processes of nation-building, while their ethnographic approach allowed them to gather original and non-obvious data on everyday practices and discourses by which citizens of the post-socialist countries reproduce and reconstruct their identities. However, both volumes display some shortcomings resulting from their renditions of the historical background, including the ethnic policies of the socialist states, as well as from constraints of the Western liberal perspective as applied to the social reality of the former Eastern Bloc.
Track Deflection of Typhoon Nesat (2017) as Realized by Multiresolution Simulations of a Global Model
Authors: Huang Ching-Yuang , Huang Chien-Hsiang , Skamarock William C.
Published: February 2019

Typhoon Nesat (2017) headed west-northwestward toward Taiwan but took a relatively larger northward deflection about 300 km away and then a leftward deflection after landfall at northern Taiwan. A global model MPAS, employing a multiresolution of 60–15–3 km mesh, is used to investigate the underlying mechanisms of the track changes. The global model simulations are capable of resolving the detailed topographical effects of the Central Mountain Range (CMR) in Taiwan, giving reasonable 5 day tracks in agreement with the observations for Typhoons Soudelor (2015) and Megi (2016), and comparing better with the observed deflection of Nesat (2017) than the regional model simulation of WRF. Sensitivity experiments indicate that flattening the CMR only partially reduces the track deflection of Nesat, while the elimination of the initial cyclone over the South China Sea disables the possible Fujiwhara effect and leads to a southward-biased track with much weaker northward deflection. The northward deflection of Nesat is mainly in response to the wavenumber-1 (WN-1) horizontal PV advection as the southerly flow east of the typhoon center is enhanced by convergence with the outer cyclonic typhoon flow and the large-scale southwesterlies. Upward motions and PV in the troposphere thus are much stronger to the east of the center than to the west, resulting in westward translation induced by negative WN-1 vertical PV advection but eastward translation induced by positive WN-1 vertical differential latent heating to the east. Near landfall, with stronger upward motions produced over the northern CMR, vertical differential latent heating averaged in 3–8-km height becomes negative and thus retards the westward translation.
Quantitative View on the Processes Governing the Upscale Error Growth up to the Planetary Scale Using a Stochastic Convection Scheme
Authors: Baumgart Marlene , Ghinassi Paolo , Wirth Volkmar , Selz Tobias , Craig George C. , Riemer Michael
Published: February 2019

Two diagnostics based on potential vorticity and the envelope of Rossby waves are used to investigate upscale error growth from a dynamical perspective. The diagnostics are applied to several cases of global, real-case ensemble simulations, in which the only difference between the ensemble members lies in the random seed of the stochastic convection scheme. Based on a tendency equation for the enstrophy error, the relative importance of individual processes to enstrophy-error growth near the tropopause is quantified. After the enstrophy error is saturated on the synoptic scale, the envelope diagnostic is used to investigate error growth up to the planetary scale. The diagnostics reveal distinct stages of the error growth: in the first 12 h, error growth is dominated by differences in the convection scheme. Differences in the upper-tropospheric divergent wind then project these diabatic errors into the tropopause region (day 0.5–2). The subsequent error growth (day 2–14.5) is governed by differences in the nonlinear near-tropopause dynamics. A fourth stage of the error growth is found up to 18 days when the envelope diagnostic indicates error growth from the synoptic up to the planetary scale. Previous ideas of the multiscale nature of upscale error growth are confirmed in general. However, a novel interpretation of the governing processes is provided. The insight obtained into the dynamics of upscale error growth may help to design representations of uncertainty in operational forecast models and to identify atmospheric conditions that are intrinsically prone to large error amplification.
The Relationship between Convective Bursts and Warm-Core Intensification in a Nonhydrostatic Simulation of Typhoon Lionrock (2016)
Authors: Oyama Ryo , Wada Akiyoshi
Published: February 2019

Typhoon Lionrock (2016) was unusual among tropical cyclones (TCs) in that it formed east of the monsoon gyre in the western North Pacific, and moved counterclockwise. It rapidly intensified in the monsoon gyre in an environment of weak upper-tropospheric winds and vertical wind shear. This study used a 3-km mesh nonhydrostatic model to examine the warm-core intensification of Typhoon Lionrock, which was associated with cyclone-scale vigorous convection [i.e., convective bursts (CBs)]. The simulation reproduced the multiple CBs at intervals of 1 day or shorter, which were related to the diurnal cycles and other short time-scale variations in the TC convection. Each CB tended to precede peak temperature anomalies near the TC center by 0–12 h, indicating that the warm-core intensification occurred due to diabatic heating released by the vigorous eyewall convection. Notably, updrafts due to convection during the intensification phase were stronger than those occurring during the mature and decay phases, and the maximum temperature anomaly of the upper-tropospheric warm core rapidly increased during eyewall formation. In addition, this study indicated that most of the asymmetric inner-core vigorous convection associated with CBs, which was induced by the vertical wind shear, contributed to the warm-core intensification. Furthermore, the budget analysis of potential temperature within the TC inner core showed that adiabatic heating due to subsidence from near the tropopause within the eye, often following CBs, was essential in developing the eye. The lag correlation suggested the lag time between the CBs and the subsidence within the eye was 3–9 h.
Admission Heart Rate Is Associated With Coronary Artery Disease Severity and Complexity in Patients With Acute Coronary Syndrome

Published: February 2019

We evaluated the relationship between admission heart rate (HR) and coronary artery disease severity and complexity in patients with acute coronary syndrome (ACS). A total of 884 patients (mean age 59 [11] years, 24.7% female) who underwent coronary angiography for ACS and were treated with primary or selective percutaneous coronary intervention were included in this cross-sectional study. The measurement of admission HR was based on the first available resting electrocardiogram after admission. The SYNTAX score (SS) was calculated. Patients with an SS ≤ 22 (n = 538) were classified as the low SS group and those with an SS > 22 (n = 346) were classified as the intermediate-to-high SS group. Admission HR was greater in the intermediate-to-high SS group compared with the low SS group (75 [10] bpm vs 67 [8] bpm, P < .001). Admission HR was positively and significantly correlated with the SS ( r = 0.475, P < .001). After multivariate analysis, admission HR (per 1 standard deviation, ie, 10 bpm) remained an independent predictor of intermediate-to-high SS (odds ratio: 3.135, 95% confidence interval: 2.538-3.873, P < .001). Admission HR is independently and positively associated with the SS. Thus, elevated admission HR may be useful to identify patients with ACS with a high coronary atherosclerotic plaque burden.
Acute pseudogout – Measure serum magnesium
Authors: Gama RM , Barkham N , Ward J , Gama R , Borovickova I
Published: February 2019

We report a 49-year-old woman with an acute swollen left knee due to acute pseudogout with chondrocalcinosis as a presenting feature of Gitelman syndrome due a novel homozygous mutation of the SLC12A3 gene. This report highlights the under-recognized importance of excluding metabolic disease, including Gitelman syndrome, in younger patients whose sole presenting feature may be chondrocalcinosis with or without pseudogout, as this may impact on management and risk of further episodes. We also suggest that chondrocalcinosis and hypomagnesaemia with or without hypokalaemia are diagnostic of Gitelman syndrome.
A short report: reflective testing in the diagnosis of hereditary haemochromatosis: results of a short retrospective study
Authors: Malton Katie , Turnock Daniel
Published: February 2019

Background

Reflective addition of iron studies to elevated ferritin results can be a useful first step towards making a diagnosis of haemochromatosis; however, the criteria for doing so are poorly defined and the efficiency of different stages of this process are not well documented. We studied the efficiency of current practice at York Teaching Hospitals NHS Foundation Trust with the aim to identify areas for improvement.

Methods

Data were gathered from the laboratory database on the number of iron studies and subsequent interpretive comments reflectively added by laboratory staff during an eight-month period. Reflective addition of iron was based on individual practice of the reporter. Standardised interpretive comments were added to suggest HFE genotyping when both the ferritin and transferrin saturation were raised. The number of patients successfully followed up and found to have pathological HFE gene mutations was used to evaluate efficiency.

Results

A total of 2651 raised ferritin results were reported during the evaluation period, which resulted in the reflective addition of 381 iron studies and 43 interpretive comments by the duty biochemists. This led to 33 requests for HFE genotyping and the identification of 13 individuals with pathological mutations. The number of iron studies reflectively added to diagnose one patient (NND) was found to be 29.3.

Conclusions

Reflective addition of iron studies and interpretive comments can assist in the early detection of patients with hereditary haemochromatosis. Better guidance for laboratory staff undertaking reflective testing and for general practitioners facilitating patient follow-up may increase the efficiency of this diagnostic process.

An equivalent circuit model analysis for the lithium-ion battery pack in pure electric vehicles
Authors: Su Jie , Lin Maosong , Wang Shunli , Li Jin , Coffie-Ken James , Xie Fei
Published: February 2019

According to the demand of vehicle lithium-ion battery pack, the splice equivalent circuit model is constructed. First, a joint experiment of intermittent discharge and hybrid power pulse characterization, basis of the requirements of parameter identification for the model, is designed to identify the parameters. Study shows that it can identify the parameters. Second, the splice equivalent circuit model of vehicle lithium-ion battery pack is simulated by MATLAB/Simulink, which shows the model is feasible to describe the vehicle lithium-ion battery pack. The simulation error of ohmic internal resistance R0 should be less than 0.05 mΩ. Study suggests that the vehicle lithium-ion battery pack has a stable discharge period within the state-of-charge range of [20%, 80%]. However, when stage of charge is below 20%, vehicle lithium-ion battery pack is no longer stable and the parameters of the splice equivalent circuit model change dramatically.
“Tell it slant”: Postcoloniality and the fiction of biographical authenticity in Hanif Kureishi’s My Ear at His Heart: Reading My Father
Authors: Munos Delphine
Published: February 2019

In Postcolonial Writers in the Global Literary Marketplace (2007), Sarah Brouillette expands on Graham Huggan’s exploration of the current entanglement between “the language of resistance” inherent to postcolonialism and “the language of commerce” intrinsic to postcoloniality (Huggan, 2001: 264). Connecting the successful marketing of postcolonial writing with the regime of postcoloniality, Brouillette argues that such a regime requires or projects a “biographical connection” (2007: 4) between text and author so that even postcolonial fiction can be thought of as offering a supposedly authentic or unmediated access to the cultural other. This article discusses Hanif Kureishi’s My Ear at His Heart: Reading My Father (2004), in which the British Asian author narrativizes his ambivalent relationship with his father and retraces the latter’s trajectory from India to the UK of the 1960s and 1970s. My aim is to show how this memoir is very much concerned with the relationship between postcolonialism and postcoloniality even as it foregrounds issues of genre, authorship, and (af)filiation. Highlighting the ambiguities and impossibilities inherent in any referential pact (see Lejeune, 1975), My Ear at His Heart not only complicates the demand for “biographical authenticity” that is seen by Brouillette to condition the niche marketing of postcolonial literatures, the memoir also alludes to the reception of Kureishi’s own work, which was framed by “autobiographical” readings of his early novels. Through an analysis of the ways in which My Ear at His Heart re-places issues of postcoloniality and genre at the heart of the father–son relationship, I wish to suggest that Kureishi still has “something to tell us” about the commodification of “minority” cultures, provided that postcolonial scholarship starts taking issues of form seriously.
The Formation of the Arab League and the United Nations, 1944–5
Authors: Wichhart Stefanie
Published: February 2019

While the Great Powers were meeting in Washington at the Dumbarton Oaks Conference, representatives of the Arab states were meeting in Egypt to draft the Alexandria Protocol, the document that would lead to the establishment of the Arab League in March 1945. The idea of Arab Unity has a long history driven by intra-regional dynamics but the form that the League ultimately took of a regional organization rather than the political union many envisioned was largely a product of the wartime environment. The Arab states found both opportunity and potential threats in the Dumbarton Oaks proposals as they worked to develop their own postwar vision. Discussions of regional councils in the months preceding Dumbarton Oaks raised fears of a western-imposed regional order and served as the center of gravity that ultimately allowed them, for the moment, to overcome regional rivalries and join together in the Arab League. This case study contributes to the decolonization of diplomatic history by placing the Arab nationalist movement in its global context and demonstrates how the Arab states, for whom unity was viewed as a pathway to independence, appropriated wartime internationalist ideals in the later war years.
Why organic farming is not the way forward
Authors: Kirchmann Holger
Published: February 2019

The aim of this article is to provide information about crop production data based on large-scale organic farming and to point toward major consequences. National statistics show lower organic yields than compiled in meta-analyses from farm- and plot-scale. Yields of organically cropped legumes were 20% and nonlegumes 40% lower than those of conventionally grown crops. Area estimates showed that almost two of three crops were legumes or legume mixtures in organic farming, whereas one of three crops was a legume in conventional cropping. Doubling land use for legumes in organic farming affected the type of food produced, being dominated by milk products and red meat. Over all crops, the organic yield gap was 35%. Since yields are lower under organic than conventional practices, more land is required to produce the same amount of agricultural crops. A 35% yield gap means that 50% more arable land is required. A demand for 50% more farmland imposes huge land use changes and makes one realize the wide-ranging environmental consequences that follow when converting to organic farming. In a relevant comparison between organic and conventional cropping systems, environmental consequences caused by land use change such as lost products (timber, fiber, energy, etc.) and lost ecosystem services (sequestered carbon in soil, wildlife, biodiversity, etc.) must be included. The concept of organic farming was founded on philosophical views about nature, not biological science. Natural means and methods were assumed to be superior. Verification of the reasoning and statements of the founders on why to abandon mineral fertilizers cannot be corroborated by science and is incorrect. Scientific evidence for the concept to abandon synthetic mineral fertilizers as nutrients for crops is lacking. The scientific community is obliged to follow rigorous scientific criteria—not biased views, prejudices, or beliefs.
Speed of Visual Acuity for Vertical Eye-Movements with a Change of Accommodation
Authors: Luria David M.
Published: February 2019

Speed of visual acuity was measured for Landolt-C targets presented above and below the line of sight as the targets were moved from 2.4 m to 0.6 m from the observer. Target recognition was faster for a downward than an upward eye movement. There was no difference in response times for the up and down eye-movements when the fixation and target distances were the same.
Continuation of Visual-Field Mapping for a Target Embedded in a Regular Background

Published: February 2019

The binocular functional visual-field, which is the area around the fixation point within which a target can be detected, was mapped for two subjects, using a peripherally presented target in a regular background. Over-all the field shapes were strikingly similar to field shapes reported previously for these two subjects and confirmed the presence of boundary irregularities for both subjects.
Contemporary Opinions on Health Issues: An Informal Look
Authors: Trinkaus John
Published: February 2019

An informal look at the opinions of a convenience sample of business students and faculty on health-care-related issues suggests some departure from a set of national norms reported in Hippocrates, a general-interest magazine in the field. The nature of the differences appears to imply a greater willingness by business students and faculty to allow patients more discretion in determining courses of action.

Comprehension of brief computer-displayed text was investigated. Question-answering ability was affected by both rate of text presentation and text difficulty. More importantly, though, text presented one word at a time was comprehended better than text presented in multiword units or chunks. Results are discussed with regard to optimizing reading from computer displays.
Reaction to Positive and Negative Behavior in Same-Sex vs Opposite-Sex Others
Authors: Kenyon Chris , Hewitt Jay
Published: February 2019

A modified version of ambivalence-amplification hypothesis was applied to a situation involving possible sex discrimination. The modified hypothesis stated that people would have a more polarized reaction to the positive and negative behaviors of an opposite-sex individual than to a same-sex individual. Male and female subjects saw four videotaped segments in which a judge made some comments toward a defendant. The four segments showed male and female judges making positive or negative comments. Subjects rated their liking for the judge after each segment. Results were consistent with the polarization hypothesis.
Perceptions of Family Learning Environments: The Influence of Sibling Background
Authors: Marjoribanks Kevin
Published: February 2019

Longitudinal data from 240 female and 260 male Australians were used to examine relationships among birth order, sibsize, and adolescents’ perceptions of family learning environments after taking into account the correlation of intellectual ability and social status on those perceptions. For the analysis, regression models were investigated that included terms to test for possible linear, interaction and curvilinear relationships. The findings provided tentative support for the sibling dilution theory, that is, after accounting for the effects of children's ability and family social status, the sibling variables continued to have some modest associations with the adolescents’ perceptions of their parents’ support for learning.
Evaluation of the Handwriting of Successful Women through the Roman-Staempfli Psychogram
Authors: Wellingham-Jones Patricia
Published: February 2019

Data on women who create satisfying lives for themselves are needed to identify the personality characteristics of strong, successful women. The handwritings of two groups (70 successful and 42 not-so-successful) of women were compared, using the Roman-Staempfli Psychogram, a graphological charting system, and nine additional categories. The women were divorced, married, or single; their ages ranged from 19 to 80 yr.; their backgrounds were socioeconomically varied. The one-way analyses of variance showed that 24 of the 38 indicators originally expected to be significantly different between the groups proved to be so. Also supporting specific hypotheses were 10 of the 14 indicators originally expected to not be significantly different. These results suggest the qualities considered important for achievement can be inferred from the handwritings of successful women and can be measured graphologically. Possible reasons for variance from the hypotheses were discussed.
Fisher and Cleveland Barrier and Penetration Scores: Correlations with Rorschach Category Scores
Authors: Jupp J. J.
Published: February 2019

Rorschach content responses which ascribe protecting and containing qualities to objects define the 1968 Fisher and Cleveland barrier index while flattened-open-fuzzy responses define their penetration index. in some samples the indices relate as a bipolar dimension, in others they are not correlated. However, in both cases there is evidence that indices assess behaviours and experiences associated with aspects of body-image boundary. It has been claimed that types of barrier responses may be unrelated and so associated with different psychological experience. It has also been suggested that correlations between indices and other variables, taken as support for their construct validity as a measure of body-image boundary are artefactual, specifically, that they represent established correlations between other Rorschach content scores and behaviours and experiences. This study examined relationships among types of barrier scores, penetration scores (obtained by different methods) and Rorschach category scores. All barrier scores were positively correlated, all penetration scores were positively related, and all barrier and penetration scores were negatively correlated. Explicable relationships were found between body boundary index scores and a few Rorschach category scores. A bipolar barrier penetration and a separate penetration dimension were isolated. The implications of these results vis à vis Fisher's 1986 contentions about the nature of boundary scores was discussed.
Deaf versus Hearing Subjects’ Recall of Words on a Distraction Task as a Function of the Signability of the Words
Authors: Spencer Stacie , Dale J. Alexander , Klions Herbert L.
Published: February 2019

Subjects, including 17 deaf and 10 hearing students in Grades 11 and 12, completed a test for memory of lists of 6 words (presented visually for 10 sec.). Subjects recalled the words in writing after a distracting task of adding pairs of digits for 10 sec. Word lists are categorized as signable with a single sign, compound or combination of signs, or finger-spelling signs only. Hearing subjects recalled significantly more words in each category than did deaf subjects. Deaf subjects recalled significantly more single-signed words than either of the other two categories. Deaf subjects did not recall more compound/combination signed words than words that could only be finger-spelled. Hearing subjects also recalled significantly more single-signed words than either of the other two categories and were not superior in either of the other categories.
Relocation of the distribution center of a motor oil producer reducing its storage capacity: A case study
Authors: González-Hernández Isidro Jesús , Martínez-Flores José Luis , Sánchez-Partida Diana , Gibaja-Romero Damián Emilio
Published: February 2019

Enterprises face the challenge of identifying, following, and controlling the performance of their processes in the whole supply chain (SC) to guarantee an adequate level of service to the client. Since the delivery of orders on time has a direct impact in the client’s satisfaction, the managers of the SC face the challenge of choosing the best location, number, and capacity of the facilities to deliver the client’s orders on time. In this paper, we address a facility relocation problem. A motor oil manufacturing company currently has a distribution center (DC) with 17,800 storage locations and 20 docks for loading and unloading, operated traditionally, and it wishes to relocate the DC to a smaller one of 10,800 storage locations operated in an automated way. However, they do not have the certainty that the relocated DC will support the distribution logistics operation to deliver the clients’ orders on time. In this research, we make a feasibility analysis of the distribution logistics operation when relocating the DC through a simulation model. For that, it was essential to analyze the main storage and distribution processes of the new DC. The main contribution of this work is the development of a simulation model that can be used to analyze the feasibility of relocating a warehouse or DC to a specific location; the model establishes the main key performance indicators that must be evaluated in the simulation. The results of the simulation show that it is feasible to implement the relocation.
Intimate Entanglements: Affects, more-than-human intimacies and the politics of relations in science and technology
Authors: Latimer Joanna , López Gómez Daniel
Published: February 2019

This article introduces Intimate Entanglements by proposing three interrelated shifts that result from juxtaposing experiences with different world-making practices at the intersection of care, technoscience and theoretical engagements with affect theory and Science and Technology Studies (STS). The first shift positions intimacy as not only relevant in STS but also as a more general epistemic concern of social scientific enquiry. The second shift is an exploration of the heterogeneous materiality of the intimate and, in particular, of its more-than-human constituencies. The third shift both reclaims and speculates about other politics of relations, including practical challenges (not only conceptual) to the way we do research. The article shows that the beings entangled, the materialities involved, the affects conveyed and the extension of the intimate all come to matter when science and technology is critically analysed, and that they challenge the traditional limits and geographies of the intimate. The paper also argues that this has important political implications for science and technology studies. By countering the invisibilisation of ‘intimate work’ through its usual association with the emotional and the domestic, the article contests the ready-made framing of the intimate as bound to the interpersonal, corporal and private. In so doing, the authors make visible the politics of relations that scientific and technological settings silently enact.
Physical Education Experiences of Alaskan Youths with Visual Impairments: A Qualitative Inquiry
Authors: Haegele Justin A. , Buckley Maggi
Published: February 2019

Introduction:

Examining the experiences of students with visual impairments about physical education can lead to a better understanding of how they perceive lessons, activities, and interactions with teachers and peers. Although research in this area of inquiry is growing, the existing literature is limited by geographic location. More specifically, most research in this area has been conducted by examining the experiences of individuals living in the lower 48 states of the contiguous United States. Thus, the purpose of this study was to explore the physical education experiences of Alaskan youths with visual impairments.

Methods:

A convenience sample of four Alaskan youths with visual impairments were recruited to participate in this study. Data were collected via semistructured face-to-face interviews, reflective field notes, and observation notes. Data were analyzed thematically using a four-step line-by-line process, and emergent themes were displayed as findings and discussed concurrently.

Results and discussion:

Two interrelated themes were constructed from the participants’ narratives. One theme, “accommodation needs met and unmet,” described the participants’ experiences with needed accommodations in physical education and the feelings they ascribed to instances where needs were met or unmet. The second theme, “deleterious peer relationships,” depicted peer relationships in physical education between the participants’ and those without visual impairments and revealed several challenging types of interactions that typified those relationships. Interestingly, although the participants in this study described participating in physical education activities that may be unique to those experienced in the lower 48 states, their experiences with peers and teachers were consistent with those portrayed in research conducted throughout the country.

Implications for practitioners:

The themes that emerged from this study should be considered by physical education personnel providing services in this, and other similar, geographic regions when planning and providing physical education programming to students with visual impairments.
Association Between Culture and Culture-Independent Microtyping in Recalcitrant Chronic Rhinosinusitis
Authors: Vaughn Andrew , Shaver Courtney , Clark David
Published: February 2019

Background:

Many different etiologies have been proposed to be responsible for the pathogenesis of chronic rhinosinusitis, including dysbiosis of the sinus microbiome. Attempts have recently been made to identify a pathogenic organism via advanced culture mechanisms. The purpose of this study is to use culture-dependent and culture-independent means of microtyping to determine whether any association exists between the quantity and quality of bacteria identified in patients with recalcitrant chronic rhinosinusitis.

Methods:

Medical records were retrospectively reviewed for patients with a history of revision sinus surgery and persistent symptoms who underwent endoscopically directed culture and underwent quantitative polymerase chain reaction analysis of the 16S ribosomal RNA of bacteria and fungi from February 1, 2014, to January 1, 2017. A total of 21 patients met the inclusion criteria. Medical records were reviewed to determine the number of bacterial isolates and relative abundance of bacteria and fungi on culture and polymerase chain reaction.

Results:

Using culture-independent techniques of examining purulent secretions in patients with recalcitrant chronic rhinosinusitis, an average of 3.61 isolates were identified per specimen, compared with culture-dependent methods that revealed 2.10 isolates per specimen ( P < .05). The dominant species identified on each culture was rarely the most abundant species identified using polymerase chain reaction techniques.

Conclusions:

Traditional culture methodologies may fail to identify potential pathogens or the dominant pathogen in patients with recalcitrant chronic rhinosinusitis with acute exacerbations.
Divorce Attitudes Among Older Adults: Two Decades of Change
Authors: Brown Susan L. , Wright Matthew R.
Published: February 2019

The authors used data from the 1994, 2002, and 2012 General Social Survey ( N = 1,450) to examine whether support for divorce has increased among adults aged 50 years and older. Consistent with the rise in the gray divorce rate, today’s older adults were more accepting of divorce than their predecessors were two decades ago. Attitudinal change was modest between 1994 and 2002, but accelerated after 2002. The acceleration was primarily due to period rather than cohort change, signaling the role of broader shifts in the meaning of marriage as it has become deinstitutionalized. Older birth cohorts and individuals who were either divorced or remarried were especially likely to hold supportive attitudes toward divorce.

The current study was aimed at assessing the extent that job-seeking networking may explain the positive association between career planning and self-perceived employability. In addition, the moderator role of political skill in strengthening the relationship between career planning and job-seeking behavior was explored. A sample of N = 2,561 students and graduates searching for jobs from one of the largest Italian universities filled out an online questionnaire. The hypotheses were tested using structural equation modeling. Results showed that the positive relationship between career planning and self-perceived employability was mediated by job-seeking networking. Furthermore, the association between career planning and job-seeking networking appeared to be stronger for people who possessed greater political skill. This study may advance the comprehension of the added value of proactive career behaviors within the process that links career planning and self-perceived employability. In addition, primary intervention aimed at maximizing graduates’ possibilities of attaining employment was suggested.

The objective of this study was to analyze risk factors for HIV-positive tests in walk-in users and in hospitalized patients in a Mexico City hospital. We undertook a cross-sectional study based on routine HIV testing and counseling service data in adults undergoing an HIV test from January 2015 to July 2017. Multivariate analysis was performed to determine risk factors for walk-in and hospitalized patients. The results showed that 2040 people tested during the period; hospitalized patients were more likely to test HIV-positive than walk-in users (18 versus 15%; p < 0.05). HIV risk factors for hospitalized patients included being men who have sex with men (MSM) (adjusted odds ratio [aOR] 7.2, 95% CI 2.0–26.5), divorced (aOR 4.4, 95% CI 1.3–14.4), having 3–5 lifetime sexual partners (aOR 2.7, 95% CI 1.0–7.4), and being in the emergency room (aOR 3.6, 95% CI 1.1–11.3), intensive care (aOR 27.2, 95% CI 3.4–217.2), or clinical pneumology wards (aOR 33.4, 95% CI 9.7–115.2). In the walk-in group, HIV risk factors included being male (aOR 2.8, 95% CI 1.3–5.9), being MSM (aOR 4.3, 95% CI 2.0–9.5), having sex while using drugs (aOR 2.3, 95% CI 1.3–4.0), being referred by a physician for testing (aOR 3.2, 95% CI 1.6–6.3), and perceiving oneself at risk (aOR 3.8, 95% CI 2.3–6.3). Differential risk factors found among hospitalized patients and walk-in testers can be helpful in designing better HIV testing strategies to increase early diagnosis and linkage to care.
Addressing Educational Needs in Managing Complex Pain in Cancer Populations: Evaluation of APAM: An Online Educational Intervention for Nurses

Published: February 2019

Context:

Cancer-related pain is associated with significant suffering and is one of the most challenging symptoms to manage. Studies indicate that front-line clinicians often lack the knowledge on best practices in cancer pain management.

Objectives:

The current project, a quality improvement (QI) initiative, evaluated the outcome of an online educational intervention for nurses on complex cancer pain management.

Methods:

An online 7-module educational intervention, Advanced Pain Assessment and Management, was offered from 2012 to 2017. Pre–post course evaluations included self-reported knowledge and confidence across cancer pain management domains. In-course competency assessments included knowledge examination, online discussion forum participation, opioid dosage calculation assignment, and small-group-based case study. A mixed-model statistical analysis was used to assess pre–post course change in pain management confidence level.

Results:

In all, 306 nurses from 89 hospitals in Ontario, Canada, were enrolled in the course; 81.4% returned the precourse survey and 71.9% successfully completed the course. The average confidence level on pain management was low at baseline (57.5%) but improved significantly post-course. In-course competency assessments ranged from 81% to 89%. Mixed-model results showed post-course improvements in confidence levels, independent of sociodemographic background, clinical role, and professional educational level. Nurses with longer years of practice and more cancer cases reported greater confidence.

Conclusion:

A facilitator-led online educational intervention focusing on complex cancer pain management can significantly improve nurses’ knowledge, confidence, and skills. Low baseline knowledge among nurses highlights the pressing need for health-care organizations to implement cancer pain management training as an integral part of health-care QI initiative.
Ethics, Equity, and Community Engagement: Urban School Administrators Rate Their Preparation Programs
Authors: Robey Philip V. , Shi Qi , Savard S. J. John
Published: February 2019

School administrators from three mid-Atlantic cities were surveyed regarding the levels of emphasis given to components from their university-based leadership preparation programs. Three components—ethics, equity, and community engagement—are explored for this article due to their influential relationship with school response to changing demographics. Using a sliding scale, participants indicate that tasks related to all three components were emphasized in their programs, with ethics highlighted the most and community engagement highlighted the least. Negative statistical significance was found between the independent variable, time since program completion, and the components equity and ethics. This indicates that those who completed their programs longer ago perceive less emphasis on the two components. An analysis follows on how educational leadership program standards may influence what programs emphasize.
Comparing Anti–Factor Xa and Activated Partial Thromboplastin Levels for Monitoring Unfractionated Heparin

Published: February 2019

Background: Lab tests such as activated partial thromboplastin time (aPTT) or anti–factor Xa (anti-Xa) levels are typically used to monitor intravenous unfractionated heparin (IV heparin), with recent evidence suggesting that anti-Xa levels may provide a more accurate measure of anticoagulation. Objective: The Lexington Veterans Affairs Health Care System transitioned from using aPTT to anti-Xa levels in January 2017. This study was conducted to evaluate the efficacy and safety of this change. Methods: This was a retrospective cohort study comparing all patients receiving IV heparin per protocol for at least 24 hours from August 1, 2016, to January 31, 2017 (aPTT group), and February 1, 2017, to July 31, 2017 (anti-Xa group). The primary objective was a comparison of IV heparin doses required to achieve goal range between the 2 cohorts. Secondary objectives included a comparison of time to therapeutic goal, percentage of time within goal range, number of rate changes until therapeutic goal, and adverse outcomes, such as number of bleeds. Results: A total of 155 patients were included in this study. Significantly higher IV heparin doses were required to achieve therapeutic goal in the anti-Xa group, despite significantly fewer IV heparin rate changes required. Anti-Xa monitoring was not associated with an increased risk of adverse events. Conclusion and Relevance: Significantly higher IV heparin doses were required to achieve therapeutic anti-Xa levels after transitioning from an aPTT-based protocol in the largely unstudied veteran population. However, the transition from aPTT to anti-Xa monitoring appears safe and efficacious in these patients.
The New Materialisms and Indigenous Theories of Non-Human Agency: Making the Case for Respectful Anti-Colonial Engagement
Authors: Rosiek Jerry Lee , Snyder Jimmy , Pratt Scott L.
Published: February 2019

Both new materialist philosophy of science and Indigenous studies scholarship have developed theories about the agency of non-human things. There has, however, been relatively little articulation between these two literatures in the qualitative social sciences. This essay looks at the possible reasons for this lack of engagement–including the relatively recent emergence of new materialism, pervasive racism within the academy, and foundational differences in the priorities and philosophical assumptions informing these two literatures. Addressing new materialist scholars, the essay inventories the ethical, political, and intellectual reasons social scientists using Karen Barad’s concept of agential realism should also be reading and citing Indigenous studies literature on agent ontologies. It makes the case that the Indigenous studies literature on agent ontologies have strengths in precisely some of the places new materialist social science is facing challenges. Examples are provided and the broader political implications of such work are examined.
