Researcher, Analyze Thyself
Authors: Saldaña Johnny
Published: October 2018

This article attempts to answer the phenomenological question, “What does it mean to be a qualitative researcher?” and an ancillary question, “What does ‘making meaning’ mean?” The author, in collaboration with selected participants at the 2018 The Qualitative Report and the International Institute for Qualitative Methodology’s Qualitative Research Methods conferences, proposes that research is devotion. Three major categories or components of devotion are purpose (personal and professional validation), belonging (communal grounding), and meaning (an enriched life). Ten subcategories or “elements of style” as qualitative researchers include meticulous vigilance of details, unyielding resiliency, visionary reinvention, social savvy, humble vulnerability, representational responsibility, finding your methodological tribes, emotional immersion, gifting your ideas, and knowing and understanding yourself.
An importance order analysis method for causes of railway signaling system hazards based on complex networks
Authors: Liu Jintao , Li Keping , Zheng Wei , Zhu Jiebei
Published: October 2018

The importance order of causes of a railway signaling system hazard is important for the arrangement of control measures for eliminating or controlling the system hazard. In order to obtain a reasonable importance order, a novel importance order analysis method based on complex networks is proposed in this article. In this article, to characterize the causes from a topological perspective, a comprehensive topology characteristic is proposed. It is built on the top of three typical topology characteristics with the weighted Euclidean distance. Then, an influence coefficient matrix is proposed to measure the causal influence between causes. Based on the proposed topology characteristic and matrix, an algorithm is designed to identify the importance order of causes. To verify the effectiveness of the proposed method, a case study on a Chinese high-speed railway signaling system hazard is performed. The results show that the proposed method is feasible for the arrangement of control measures to eliminate or control system hazards and performs better than the traditional complex network-based methods in terms of avoiding conflicting and rough results.
Is Cooking Still a Part of Our Eating Practices? Analysing the Decline of a Practice with Time-Use Surveys
Authors: Plessz Marie , Étilé Fabrice
Published: October 2018

People now spend less time doing housework in general, and cooking in particular. So is cooking still a central feature of our daily eating practices? This article compares trends in household cooking durations in France and the USA in the period 1985–2010 using time-use surveys and practice theory. We ask how the association between cooking and eating at home has changed over time, and how it has contributed to the decline in the time spent on household cooking. Descriptive statistics show that US households spent 20 minutes less time per day cooking in 2010 than in 1985 (15 minutes less time per day in France). Linear regressions indicate that the association between cooking duration and the number of eating events at home has declined in the USA but not in France. The Blinder-Oaxaca decomposition method points to this fact as the primary reason for the change in cooking time in the USA; in France, decreased cooking time is accounted for primarily by changes in population characteristics. French and American food practices have followed gradually diverging trajectories, with cooking less a feature of eating practices – even at home – in the USA, whereas the association between eating and preparing food at home remains stable in France.

Authors: Miura Kousei , Kadone Hideki , Koda Masao , Nakayama Keita , Kumagai Hiroshi , Nagashima Katsuya , Mataki Kentaro , Fujii Kengo , Noguchi Hiroshi , Funayama Toru , Abe Tetsuya , Suzuki Kenji , Yamazaki Masashi
Published: October 2018

Purpose:

To evaluate a newly developed system for dynamic analysis of gait kinematics and muscle activity.

Methods:

We recruited 10 healthy men into this study. Analyses of three-dimensional motion and wireless surface electromyogram (EMG) were integrated to achieve synchronous measurement. The participants walked continuously for 10 min under two conditions: comfortable and quick pace. Outcome measures were joint angles of the lower limbs determined from reflective markers and myoelectric activity of trunk and lower limbs determined from EMG sensors, comparing comfortable and quick gait pace.

Results:

Lower limb joint angle was significantly greater at the quick pace (maximum flexion of the hip joint: 4.1°, maximum extension of hip joint: 2.3°, and maximum flexion of the knee joint while standing: 7.4°). The period of maximum flexion of the ankle joint during a walking cycle was 2.5% longer at a quick pace. EMG amplitudes of all trunk muscles significantly increased during the period of support by two legs (cervical paraspinal: 55.1%, latissimus dorsi: 31.3%, and erector spinae: 32.6%). EMG amplitudes of quadriceps, femoral biceps, and tibialis anterior increased significantly by 223%, 60.9%, and 67.4%, respectively, between the periods of heel contact and loading response. EMG amplitude of the gastrocnemius significantly increased by 102% during the heel-off period.

Conclusion:

Our gait analysis synchronizing three-dimensional motion and wireless surface EMG successfully visualized dynamic changes in lower limb joint angles and activity of trunk and lower limb muscles induced by various walking speeds.
Do the dynamic stress mobility radiographs predict the postoperative vertebral height restoration, kyphosis correction, and cement volume injected after vertebroplasty for osteoporotic thoracolumbar vertebral fractures with intravertebral cleft?
Authors: Chiu Chee Kidd , Lisitha Kulathunga Arachchige , Elias Dahlia Munchar , Yong Voon Wei , Chan Chris Yin Wei , Kwan Mun Keong
Published: October 2018

Background:

This prospective clinical–radiological study was conducted to determine whether the dynamic mobility stress radiographs can predict the postoperative vertebral height restoration, kyphosis correction, and cement volume injected after vertebroplasty.

Methods:

Patients included had the diagnosis of significant back pain caused by osteoporotic vertebral compression fracture secondary to trivial injury. All the patients underwent routine preoperative sitting lateral spine radiograph, supine stress lateral spine radiograph, and supine anteroposterior spine radiograph. The radiological parameters recorded were anterior vertebral height (AVH), middle vertebral height (MVH), posterior vertebral height (PVH), MVH level below, wedge endplate angle (WEPA), and regional kyphotic angle (RKA). The supine stress versus sitting difference (SSD) for all the above parameters were calculated.

Results:

A total of 28 patients (4 males; 24 females) with the mean age of 75.6 ± 7.7 years were recruited into this study. The mean cement volume injected was 5.5 ± 1.8 ml. There was no difference between supine stress and postoperative radiographs for AVH ( p = 0.507), PVH ( p = 0.913) and WEPA ( p = 0.379). The MVH ( p = 0.026) and RKA ( p = 0.005) were significantly less in the supine stress radiographs compared to postoperative radiographs. There was significant correlation ( p < 0.05) between supine stress and postoperative AVH, MVH, PVH, WEPA, and RKA. The SSD for AVH, PVH, WEPA, and RKA did not have significant correlation with the cement volume ( p > 0.05). Only the SSD-MVH had significant correlation with cement volume, but the correlation was weak ( r = 0.39, p = 0.04).

Conclusions:

Dynamic mobility stress radiographs can predict the postoperative vertebral height restoration and kyphosis correction after vertebroplasty for thoracolumbar osteoporotic fracture with intravertebral clefts. However, it did not reliably predict the amount of cement volume injected as it was affected by other factors.
Beyond the hospital infection control guidelines: a qualitative study using positive deviance to characterize gray areas and to achieve efficacy and clarity in the prevention of healthcare-associated infections

Published: October 2018

Background

The literature is replete with attempts to design and promote customized guidelines to reduce infections during the care continuum. Paradoxically, these efforts sometimes result in gray areas where many staff members are unaware of what is required of them, which then leads to confusion, frustration, and uncertainty.

We coined the phrase “gray areas” in this context to encompass the variety of situations on the care continuum that are not addressed in the accepted guidelines, and where staff members are unsure of how to proceed.

The purpose of the present study was to characterize the gray areas that were reported by staff and to identify the practices of Positive Deviance (PD) individuals. We define to PD individuals as people who independently develop creative solutions to solve problems not identified by the majority in their community.

Methods

A qualitative constructivist research methodology was used that included personal interviews, observations and video recordings of identified PD practices to enhance infection control. The study was conducted January through March 2018, in two Intensive Care Units (ICU) units at Hadassah Hospital, Jerusalem, Israel. Personal interviews were conducted with 82 staff members from the General ICU (GICU) and Medical ICU (MICU).

Results

The study confirmed that guidelines cannot cover all the different situations that arise during the care continuum and can paradoxically result in the increased spread of hospital infections. Our study found there are numerous individuals who independently develop and implement solutions for gray areas. The creative and practical solutions of PD individuals can address the barriers and difficulties on the care continuum that were encountered by the staff in their communities. For example, inserting a central venous line is a complex practice in the general guidelines, while the PDs provided clear situation-specific solutions not covered in the guidelines.

Conclusions

The recommendations of the present study are to encourage hospital personnel to create their own solutions for various situations on the care continuum, and to disseminate them within their units to achieve a bottom up change, in lieu of investing in new or specific written guidelines.
Health-Related Quality of Life in Patients Treated With Antiretroviral Therapy Only Versus Chemotherapy and Antiretroviral Therapy for HIV-Associated Kaposi Sarcoma: A Randomized Control Trial
Authors: Shaik Fahmida , Uldrick Thomas S. , Esterhuizen Tonya , Mosam Anisa
Published: October 2018

Purpose

In sub-Saharan Africa, Kaposi sarcoma (KS) is the most common HIV-associated cancer. KS causes substantial morbidity, and treatment goals should emphasize quality of life (QOL). Antiretroviral therapy (ART) is indicated, and early chemotherapy significantly improves tumor regression. The effect of ART alone or with chemotherapy on QOL in treatment-naïve South Africans with HIV-associated KS was assessed.

Methods

KAART (Kaposi Sarcoma AIDS Anti-Retroviral Therapy) is a randomized, controlled, open-label trial of ART versus ART plus chemotherapy. Crossover between arms was allowed for patients with progressive disease. Eighty-nine percent of patients had advanced tumor burden. Within KAART, QOL measured by European Organization for Research and Treatment of Cancer-QLQ-C30 questionnaire evaluated functional and symptom domains and global QOL. Intragroup changes between baseline and month 12 (Wilcoxon rank sign test), changes between the arms (Mann-Whitney test), and the relationship between responses, determined by AIDS Clinical Trial Group criteria and QOL measures (Kruskal-Wallis test), were evaluated. P values < .01 were considered significant.

Results

QOL information was available for 111 of 112 patients. Significant improvements over 12 months were seen in global health status and functional scales (emotional, cognitive, and social scales; not physical and role function). Most symptom scales (fatigue, pain, dyspnea, insomnia, appetite, diarrhea, and constipation) also showed significant improvement. There were no statistically significant changes between arms in intention-to-treat analysis. Patients showing a response to the tumor (complete or partial) reported significantly increased global QOL ( P < .001), pain relief, and improved role functioning. Adherence, adverse events, HIV viral load, and CD4 count did not correlate with global QOL.

Conclusion

African patients with HIV-associated KS derive a significant benefit in QOL from ART and tumor regression.
Financial Toxicity in Adults With Cancer: Adverse Outcomes and Noncompliance
Authors: Knight Thomas G. , Deal Allison M. , Dusetzina Stacie B. , Muss Hyman B. , Choi Seul Ki , Bensen Jeannette T. , Williams Grant R.
Published: October 2018

Purpose:

Because of the escalating cost of cancer care coupled with high insurance deductibles, premiums, and uninsured populations, patients with cancer are affected by treatment-related financial harm, known as financial toxicity. The purpose of this study was to describe individuals reporting financial toxicity and to identify rates of and reasons for affordability-related treatment noncompliance.

Methods:

From May 2010 to November 2015, adult patients (age ≥ 18 years) with cancer were identified from a Health Registry/Cancer Survivorship Cohort. Financial toxicity was defined as agreement with the phrase “You have to pay for more medical care than you can afford” from the Patient Satisfaction Questionnaire-18. Logistic regression and Fisher exact tests were used to compare groups.

Results:

Of 1,988 participants, 524 (26%) reported financial toxicity. Patients reporting financial toxicity were more likely age 65 years or younger, female, nonwhite, non-English speaking, not married, less educated, and to have received a diagnosis more recently (all P < .001). Participants with financial toxicity were more likely to report noncompliance with medication, owing to inability to afford prescription drugs (relative risk [RR], 3.55; 95% CI, 2.53 to 4.98), and reported forgoing mental health care (RR, 3.89; 95% CI, 2.04 to 7.45), doctor’s visits (RR, 2.98; 95% CI, 1.97 to 4.51), and medical tests (RR, 2.54; 95% CI, 1.49 to 4.34). The most endorsed reasons for delayed care were not having insurance coverage and being unable to afford household expenses.

Conclusion:

More than 25% of adults with cancer reported financial toxicity that was associated with an increased risk for medical noncompliance. Financial toxicity remains a major issue in cancer care, and efforts are needed to ensure patients experiencing high levels of financial toxicity are able to access recommended care.
Heparin Resistance due to an Acquired Antithrombin Deficiency in a Patient With Sickle Cell Disease During a Pregnancy Complicated by Bilateral Pulmonary Emboli: A Case Report
Authors: Wells Ashley V. , Zarkhin Eli , Weiner Menachem M. , Katz Daniel
Published: October 2018

We report a 31-year-old woman with sickle beta thalassemia zero who presented at 21 weeks gestational age with multiple bilateral pulmonary emboli and no hemodynamic instability. Acquired antithrombin deficiency was suspected due to a refractory response to therapeutic anticoagulation with enoxaparin, unfractionated heparin, and fondaparinux, and a reduced antithrombin antigen level. At 26 4/7 weeks, she developed signs concerning for increased pulmonary clot burden. To avoid the use of alternative anticoagulants that may cross the placenta and impact the fetus, a planned cesarean delivery was performed without complication at 27 weeks gestation. Both mother and child experienced successful long-term outcomes.
Sleep regulates visual selective attention in Drosophila

Published: October 2018

Although sleep deprivation is known to impair attention in humans and other mammals, the underlying reasons are not well understood, and whether similar effects are present in non-mammalian species is not known. We therefore sought to investigate whether sleep is important for optimizing attention in an invertebrate species, the genetic model Drosophila melanogaster. We developed a high-throughput paradigm to measure visual attention in freely-walking Drosophila, using competing foreground/background visual stimuli. We found that whereas sleep-deprived flies could respond normally to either stimulus alone, they were more distracted by background cues in a visual competition task. Other stressful manipulations such as starvation, heat exposure, and mechanical stress had no effects on visual attention in this paradigm. In contrast to sleep deprivation, providing additional sleep using the GABA-A agonist 4,5,6,7-tetrahydroisoxazolo-[5,4-c]pyridine-3-ol (THIP) did not affect attention in wild-type flies, but specifically improved attention in the learning mutant dunce. Our results reveal a key function of sleep in optimizing attention processes in Drosophila, and establish a behavioral paradigm that can be used to explore the molecular mechanisms involved.
Long-term strategies in patients with unprovoked venous thromboembolism
Authors: Prandoni P.
Published: October 2018

Once anticoagulation is stopped, the risk of recurrent venous thromboembolism (VTE) over years approaches 40 % of all patients with a first episode of VTE. The risk is twice as high in patients with unprovoked VTE than in those with minor (either transient or persistent) risk factors of thrombosis. Although the latest international guidelines suggest indefinite anticoagulation for most patients with a first episode of unprovoked VTE, strategies that incorporate the assessment of residual vein thrombosis and D-dimer have the potential to identify a substantial proportion of subjects in whom anticoagulation can be safely discontinued. For those patients in whom anticoagulation cannot be discontinued, new opportunities are offered by the availability of low-dose anti-Xa compounds, which have been found to possess an extremely favorable benefit/risk profile.
EHIT after thermoablation
Authors: Leo M. , Romano R. , Di Mitri R.
Published: October 2018

Aim: After 10 years of experience, we evaluated the incidence and management of endothermal heat-induced-thrombosis (EHIT), i.e. saphenous vein thrombosis following endothermic treatment of saphenous vein re-flux.

Methods: From 2006 to 2016 data were retrospectively collected on 840 patients undergoing saphenous vein treatment by laser and radiofrequency technique. All patients were treated with tumescent local anaesthesia in an ambulatory setting to promote early mobilization. Class II compression stockings and heparin were recommended for 5 days post-operatively.

Results: EHIT was observed in 15 patients from a total of 992 saphenous veins which were evaluated (1,5 %). 14 patients treated by EVLA had EHIT 1, one patient by RFA had EHIT 2, complicated by pulmonary embolism. All EHIT patients were treated by low weight molecular heparin. 980 nm laser and bare-tip fibres had been used in EVLA-EHIT patients. EHIT was not observed in patients treated by 1470 nm laser and radial fibres.

Conclusions: Latest generation technology, the ambulatory setting and local anaesthesia probably contributed to the low incidence of EHIT reported. Further studies are necessary for a better acquaintance of these complications and to facilitate the development of specific guidelines.

Die konservative Therapie der tiefen Bein-/ Beckenvenenthrombose (TVT) ist mit einem hohen Risiko für die Entwicklung eines post-thrombotischen Syndroms korreliert. Solche Folgeschäden an den tiefen Venen können nur durch invasive Maßnahmen vermieden werden. Dies kann durch Rekanalisation der verschlossenen Venen und Wiederherstellung der Funktion des Klappenapparates mit chirurgischen, fibrinolytischen und interventionellen Methoden erreicht werden.
Adipositas-assoziierte Lymphödeme – unterschätzt und unterbehandelt
Authors: Bertsch T.
Published: October 2018

Der weltweite Anstieg der Adipositasprävalenz – die WHO spricht bereits von einer Adipositasepidemie – hat auch eine dramatische Veränderung innerhalb der Lymphologie zur Folge. Während „klassisch sekundäre” Lymphödeme nach onkologischen Operationen aufgrund verbesserter OP-Techniken abnehmen, steigt die Zahl von Patienten mit Lymphödemen, die Adipositas-assoziiert, sind exponentiell an. Dieser Wandel im lymphologischen Patientengut wird aktuell noch weitgehend unterschätzt – häufig auch negiert. So ist dieses Thema sowohl auf wissenschaftlichen Kongressen als auch in der Fachliteratur, wenn überhaupt nur marginal repräsentiert. Im klinischen Umgang dominiert vor allem Hilflosigkeit gegenüber diesen Patienten. Dabei ist der pathophysiologische Zusammenhang zwischen Adipositas und Lymphödem inzwischen gut belegt. Adipositas kann Lymphödeme verursachen bzw. bestehende Lymphödeme verschlechtern. Therapiekonzepte, die isoliert das Lymphödem fokussieren, die Adipositas aber als wesentliche Ursache ignorieren, sind daher nicht zielführend. Ebenso kontraproduktiv ist ein therapeutischer Ansatz, der Adipositas mittels Diäten bzw. durch kommerzielle Gewichtsreduktionsprogramme behandelt. Diäten und Gewichtsreduktionsprogramme haben im Langzeitverlauf bisher nur eines bewiesen – dass sie scheitern. In der Földiklinik werden adipöse Patienten mit Lymphödemen (auch mit Lipödemen) im Rahmen eines multimodalen Adipositasprogramm behandelt. In diesem Programm werden u. a. internistische, psychologische, ggf. auch adipositaschirurgische und plastisch-chirurgische Therapieoptionen angewandt; die Betreuung der Patienten ist langfristig angelegt. Entgegen Vermutungen ist die Therapie von Patienten mit Adipositas-assoziierten Lymphödemen meist sehr dankbar, dankbar weil Patienten nicht nur eine essenzielle Verbesserung ihres Lymphödemes erfahren, dankbar auch, weil viele Patienten durch die im Rahmen eines adipositaschirurgischen Eingriffes erfolgte Gewichtsreduktion wieder in ein normales, weitgehend gesundes Leben zurückkehren.
Adipositas und chronische Inflammation bei phlebologischen und lymphologischen Erkrankungen
Authors: Faerber G.
Published: October 2018

Die Prävalenz der Adipositas ist in den letzten 15 Jahren weiter stark angestiegen. Dabei fällt besonders die deutliche Zunahme der morbiden Adipositas auf, die wiederum bei den Älteren besonders ausgeprägt ist. Da mit dem Alter auch venöse Thromboembolien, chronisch venöse Insuffizienz und sekundäre Lymphödeme zunehmen, steigt die Zahl der Patienten mit venösen oder lymphatischen Erkrankungen, die gleichzeitig schwer adipös und häufig multimorbide sind, überproportional an. Die Adipositas, vor allem die viszerale, verschlechtert alle Ödemerkrankungen, erhöht das Risiko für thromboembolische Erkrankungen und postthrombotisches Syndrom und kann alleinige Ursache sein für die Adipositas-assoziierte funktionelle Veneninsuffizienz ohne Nachweis von Obstruktion oder Reflux. Das Adipositasassoziierte Lymphödem stellt inzwischen den größten Anteil unter den sekundären Lymphödemen. Mehr als 50 Prozent der Lipödempatientinnen sind adipös, die bei ihnen im Verlauf zu beobachtenden sekundären Lymphödeme in der Regel Folge der Adipositas, nicht des Lipödems. Die Symptomatik wird bei allen Krankheitsbildern durch Gewichtsreduktion gebessert. Neben mechanischen Faktoren wie der Erhöhung des intraabdominalen und intertriginösen Drucks, der wiederum zu einer venösen Drucksteigerung in den Beingefäßen führt, sind es vor allem die durch die Zunahme des viszeralen Fettgewebes verursachten metabolischen, chronisch inflammatorischen und prothrombotischen Prozesse, die für diese Zusammenhänge verantwortlich sind, erkennbar an niedrigen Spiegeln von Adiponektin und hohen von Leptin, Insulin, intaktem Proinsulin, PAI-1 sowie proinflammatorischen Zytokinen (Il-6, Il-8, TNF-α). Therapeutische Maßnahmen müssen also in erster Linie auf die Reduktion der viszeralen Adipositas und damit der Hyperinsulinämie bzw. der Insulinresistenz sowie auf die Bekämpfung der chronischen Entzündung abzielen.
Varizenchirurgie bei Adipositas
Authors: Donath M. , Buhr J. K. , Bruning G.
Published: October 2018

Die operative Sanierung der Varikosis stellt bei korrektem intraoperativen Management auch bei adipösen Patienten eine hervorragende Therapieoption dar. Bei der operativen Sanierung der Vena saphena parva und der Seitenastvarikosis ist das Körpergewicht vernachlässigbar, die operative Therapie der Vena saphena magna muss jedoch gewichtsadaptiert geplant und angepasst werden: Der operative Zugang sollte oberhalb der Leistenbeuge und ausreichend groß gewählt werden, die Stumpfligatur mit nicht resorbierbarem Nahtmaterial doppelt ligiert und das Stumpfendothel koaguliert werden. Crossenrezidive stellen insbesondere bei adipösen Patienten sowohl nach operativer Sanierung der Varikosis, als auch nach endovenösen Therapieverfahren eine operative Herausforderung dar. Die Komplikationsrate bei operativer Sanierung ist sehr niedrig. Die Infektionsrate liegt bei adipösen Patienten nur marginal oberhalb derer von Patienten mit einem BMI < 30. Eine Risikoeinschätzung von endovenösen Therapien bei adipösen Patienten steht aktuell aus. Es besteht allerdings eine höhere Rezidivneigung bei größerlumigen Gefäßen.
Use of Stimulan absorbable calcium sulphate beads in revision lower limb arthroplasty
Authors: Kallala R. , Harris W. Edwin , Ibrahim M. , Dipane M. , McPherson E.
Published: October 2018

Aims

Calcium sulphate has traditionally been used as a filler of dead space arising during surgery. Various complications have been described following the use of Stimulan bio-absorbable calcium sulphate beads. This study is a prospective observational study to assess the safety profile of these beads when used in revision arthroplasty, comparing the complication rates with those reported in the literature.

Methods

A total of 755 patients who underwent 456 revision total knee arthroplasties (TKA) and 299 revision total hip arthroplasties (THA), with a mean follow-up of 35 months (0 to 78) were included in the study.

Results

A total of 32 patients (4.2%) had wound drainage, and this was higher with higher bead volumes and in McPherson grade C patients. There was also a significantly higher bead volume in the 41 patients who developed hypercalcaemia, two of which were symptomatic (p < 0.0001). A total of 13 patients (1.7%) had heterotopic ossification (HO). There was no statistically significant relationship between the development of HO and bead volume (p > 0.05).

Conclusion

The strength of this study lies in the large number of patients and the detailed data collection, making it the most comprehensive report available in the literature on the use of calcium sulphate-based bone substitutes.

Acute Charcot foot is a diagnostic challenge. The exact pathophysiology is not fully understood. Acute Charcot foot is often present with a history of trauma or cellulitis which does not respond to antibiotics. The condition is best managed within a multidisciplinary team. The mainstay of the treatment is mechanical off-loading and total contact casting. Surgery is reserved for select cases.

Rupture, repression, repetition: The Algerian War of Independence in the present
Authors: Hartley Daniel , Ivey Beatrice
Published: October 2018

What are the legacies of the Algerian War of Independence in the present? More specifically, how do the Algerian War of Independence and its subsequent memorializations force us to reconceptualize historical temporality itself (of which the ‘legacy’ is but one variation)? The following introduction to this special issue provides an overarching framework for multiple answers to these questions. The first half of the introduction focuses on the philosophical and conceptual afterlives of the Algerian War in contemporary French critical thought. In doing so, it attempts to delineate the significant political import of historical temporality as such, setting out a basic problematic to which the articles that follow can be seen variously to respond. In the second part of the introduction, the general cultural and historical legacies of the Algerian War of Independence, and the ‘mnemonic forms’ (Erll 2011) of rupture, repression and repetition that mediate them, come into focus: the ‘rupture’ from a colonial past, the Freudian ‘repression’ of traumatic history, and the ostensible ‘repetition’ of violence in the present. In general, the introduction hopes to open a dialogue with works conducted on these ‘forms’, scrutinizing the effects they have had on the various re-imaginings of the war and its transnational legacies, yet without foreclosing other forms this history may take.
The influence of French colonial humanism on the study of late antiquity: Braudel, Marrou, Brown
Authors: Hunt Thomas E.
Published: October 2018

Late antiquity is a sub-discipline of history. It is also a particular way of representing the time and space of the past. Studies in late antiquity tend to focus on the culture and society of the late Roman world. This article argues that this way of imagining time and space and people derives from francophone debates about colonial governance that were current in the 1920s and 1930s. This colonial humanism provided the context for two francophone authors whose work heavily influenced the formation of late antiquity: Fernand Braudel and Henri Marrou. This article shows how Braudel and Marrou were influenced by colonial humanism and how this influence shaped the formation of late antiquity. Historiographical accounts of the study of late antiquity have noted a recurring preoccupation with modernity. This article argues that late antiquity is modern to the extent that it is dependent on the colony for its constitution.
Regulation and co-regulation of product placement for OTT SVODs: The case of Netflix
Authors: Dagnino Gloria
Published: October 2018

Commercial communications constitute one of the policy areas where differences between traditional broadcasting media and over-the-top (OTT) subscription video on-demand services (SVODs) emerge more dramatically. This article focuses on the exemplary case of global market leader Netflix to examine how this US-born company has been adjusting to EU regulation on product placement (PP) identification. Moreover, the article presents and discusses some of the criticisms that were raised with regard to Netflix’s supposed violation of the ban on the placement of tobacco products. The article argues that Netflix still fails to adequately disclose PP to its viewers. The article also advances a proposal for co-regulation on these matters, in light of the upcoming revised version of the EU Audiovisual Media Services Directive (AVMSD). An effective regulation of PP in OTT SVOD programmes is essential because watching Internet-based television is ever more a mainstream habit, particularly among young demographics, and because PP is a key revenue source for ad-free services like Netflix.

In this essay, we locate and explore new literary practices and expressions in Indian digital spaces such as SMS novel and social media narratives: poetry, flash fiction, twitterfiction which are not considered as electronic literature in India.  The integration of technology and creativity is not a novel phenomenon in Indian literature where one can find the narrative tradition of ancient Indian literature which includes poetical words, paintings, and music, for instance, Pattachitra, Ragamala paintings and Chitra Kavi. Similarly, new literary practices and expressions in the digital environment include literary artefacts such as interfaces, images, audio and videos. These works serve as a gateway to exciting electronic literature in India.

‘I blamed this all on moving to Texas’: Fostering Sense of Place through Locative Literature among US Latina Girls
Authors: Silva Claudia Cristina da , Nisi Valentina , Straubhaar Joseph
Published: October 2018

This study explores how US Latina girls, in Central Texas, may develop a stronger sense of place and belonging through the grasping and crafting of locative literature. This work presents the results of a field study, in which training about locative narratives and locative media was provided during two different occasions. Firstly, a four-day workshop was conducted within the context of a summer camp with girls organized by a non-profit organization called Latinitas, based in Austin, Texas, USA. Secondly, the training was provided within the context of an after-school program, in a middle school, given also by Latinitas, to girls age ranging from 11 to 13, during five lessons spanning over five weeks. We found that the process of creating narratives rooted in the concept of place helped the participants to reflect on the location where they live, their locality, and their identity.
The cosmonaut: A Digital Creation
Authors: Luiz dos Santos Alckmar
Published: October 2018

The cosmonaut, by Alckmar Santos, Wilton Azevedo and Adir Filho, like any digital artistic work, has to deal with the increasingly rapid obsolescence of techniques and technologies. In this case, the entire creation process lasted for about four years and was subject to a number of substantial changes in the programming strategy as well as in the tools and programs used. In our case, along with the story we wanted to tell — an epiphanic experience experienced by a cosmonaut —, several elements became part of the navigation environment of The cosmonaut, associating to this the difficulty of dealing with the time that passes and never fails to imprint its marks, either in the creation itself, or in the way in which it can be read. In short, if our creation intends to tell part of the life of a cosmonaut culminating in his epiphanic experience in outer space, it also intends to provide the readers with an epiphanic experience that they will build with their own memories and their strategies of understanding and interacting within the digital work. We intend to describe this process of creation, as well as analyze this work.
Can We (Still) Speak of a ‘French’ Digital Literature?
Authors: Cronin Susie
Published: October 2018

This article explores the conditions of emergence of digital and computer-assisted literatures in the French context. Noting the importance of exhibitions in particular in contributing to the development of digital works and aesthetics, the article explores what offerings and concessions are there in considering the emergence and elaboration of such literatures through an approximate national frame.
«Como si absolutamente no hubiese intervenido tal guerra»: Economía familiar y negociación femenina durante la Guerra de Sucesión española.
Authors: Zamora Rodríguez Francisco
Published: October 2018

Este artículo aborda, a través de un estudio de caso, el papel jugado por figuras femeninas en la recuperación del patrimonio familiar tras su pérdida debido a un conflicto bélico. La familia Silva, de origen portugués, mantuvo el consulado español en Livorno durante más de un siglo. A inicios del siglo XVIII perdió su feudo como consecuencia de la Guerra de Sucesión española (1701-1713). En efecto, Andrés de Silva, cónsul español en Livorno, obtuvo el título de marqués de la Banditela con feudo en el Estado de los Reales Presidios en Toscana. Tras la ocupación de estos territorios por las tropas austrascistas en 1707, la familia puso en marcha sus contactos y agentes para poder recuperar la jurisdicción sobre estas propiedades con lo que se orquestaba la articulación de un amplio espacio. En este artículo se analiza, por tanto, no solamente la promoción social de esta familia, sino también los efectos producidos por este conflicto bélico sucesorio y las estrategias para la recuperación del patrimonio familiar. Se pretenderá calibrar el impacto del viaje de Maria de Grunembergh (viuda del cónsul) por España e Italia con el objetivo de preservar los intereses familiares.
Poder e territorialização na América portuguesa (segunda metade do século XVIII)
Authors: De Almeida Santos Antonio Cesar
Published: October 2018

En este trabajo, nuestro objetivo es presentar y discutir algunas de las acciones de la Corona portuguesa realizadas en la segunda mitad del siglo XVIII, que tenían el propósito de institucionalizar la ocupación de sus dominios en América. Tales acciones comprendieron la identificación de territorios, medir distancias entre poblaciones y contar y clasificar la población; también interesó a la Corona instalar municipios en regiones que carecían de este aparato administrativo, de tal modo que, en el plazo de cinco decenas de años, se crearon casi 130 municipios (contra cerca de 90 ya existentes). Así, con base en la documentación administrativa de la época, se verifica que, en la segunda mitad del siglo XVIII, se puso en práctica una política que, con relativo éxito, garantizó la posesión y la integridad del territorio que vino a constituir Brasil.
Professional Development for New Classroom Spaces: Extending the Concerns-Based Adoption Model
Authors: Haines Karen Joy
Published: October 2018

This article outlines how a tertiary institution designed professional development, during the first year of a long-term building initiative, to support teachers moving into new collaborative learning spaces. The Concerns-Based Adoption Model (CBAM) is used to reflect on professional development strategies employed to support teachers into using new classroom spaces. The stages of the CBAM were useful in considering the value of resources created for teacher development. The paper concludes with a discussion as to how effective the model proved to be in relation to teachers’ expressed concerns, and suggests expanding the CBAM parameters to reflect the complexity of professional development design for next-generation learning spaces.
Postgraduate Supervision in the United Kingdom and Germany: A Comparative Study of Factors Influencing the Supervisory Relationship
Authors: Feraboli Omar
Published: October 2018

This paper aims to examine and assess the approaches to postgraduate supervision in the United Kingdom (UK) and in Germany; the factors determining the differences between the two approaches and investigating their impact on the PhD supervision relationship. I combine personal reflections and experiences with the existing literature and with indices of performance and level of internationalisation of British and German universities. I examine several aspects and factors that affect the academic environment and hence determine differences across the British and German university systems, which are finally reflected in the approaches to postgraduate supervision.
Teaching ‘Networking with Others’: A Reflective Account
Authors: Turner-Wilson Angela
Published: October 2018

Reflective practice is about seeing yourself and your life differently. It is a method of self-appraisal that, when used in academia, has the potential to provide insights that are not always immediately apparent to the practitioner. The author of this paper shares a piece of structured reflection based on Gibbs’s (1988) framework. This personal narrative relates to a teaching session entitled, ‘Networking with Others’ that was delivered to UK and International postgraduate health care students. It is this activity that forms the basis of this reflective work. A number of educational issues are considered as the reflection unfolds, many relating to methods and modes of delivery. The final part of this paper reports on an action plan developed to improve the session. This includes the adoption of more collaborative working in order to support the student’s professional as well as academic needs. It is anticipated that this new workshop style session will improve the learning experience, and provide students with a firm base from which to grow their networking skills for the future. In addition, the plan may offer suggestions for anyone running similar sessions throughout the UK and the world.
Beginning a Conversation on Teaching About Empathy in Practice
Authors: Hughes Kirsty , Alexjuk Eva Joanna , Paterson Jessie , Whittington Rachel , Spielman Stacy
Published: October 2018

This ‘On the Horizon’ paper presents insights from a small interdisciplinary project exploring student perspectives on the role of empathy in professional training and practice. Using a qualitative methodology, this study provides some initial thoughts around four areas identified by the researchers. All the students, from veterinary, nursing and dementia health studies, defined empathy using classic definitions similar to those published in academic literature, but some with more in practice experience showed how this had modified over time. The vet students did recognise empathy to clients as important but admitted that the animals were their first priority, which at times caused tension with how they related to the client. Even the students with limited work experience recognised that often the expression of empathy had to be balanced against time and other demands, leading to stress and in some cases a feeling of a loss in their caring ability. Role models were mentioned by the students as key influencers in their expression of empathy – one nursing student stated that they had been encouraged to “harden up” rather than outwardly express empathy. When asked about how the role of empathy in practice was taught, most of the students stated this was explicit in their programmes and they would welcome more formal discussion and time provided to this topic. The researchers are now aiming to carry out a larger study to explore this further across a number of health care professions with the aim to provide guidance to aid educators involved in teaching students in these areas.

Your country for sale?: Understanding the citizenship by investment
Authors: Özbek Nimet
Published: October 2018

Where is the cheapest place to buy citizenship? With this question used as a heading in a BBC News Business section, by the reporter Kim Gittleson, New York, We got an idea of writing an academic paper concerning this issue, which is very controversial.Some people call it citizenship for sale and others call it citizenship by investment; but what is really the difference? This is a scheme of acquiring citizenship rather than yours in case you accept to pay a predetermined sum of money or under a form of investment, it is only made to attract rich individuals and raise the revenues of that country you are applying for citizenship.In this paper, we will analyze this kind of acquiring citizenship in comparison with the normal way of gaining another country’s nationality within the spirit of international human rights law.
