Published: April 2020

In this study, we aim to contribute to the field of critical health communication research by examining how notions of mental health and illness are discursively constructed in newspapers and magazines in six European countries and how these constructions relate to specific understandings of mental health literacy. Using the method of cluster-agon analysis, we identified four terminological clusters in our data, in which mental health/illness is conceptualized as “dangerous,” “a matter of lifestyle,” “a unique story and experience,” and “socially situated.” We furthermore found that we cannot unambiguously assume that biopsychiatric discourses or discourses aimed at empathy and understanding are either exclusively stigmatizing or exclusively empowering and normalizing. We consequently call for a critical conception of mental health literacy arguing that all mental health news socializes its audience in specific understandings of and attitudes toward mental health (knowledge) and that discourses on mental health/illness can work differently in varying contexts.
Falling Down the Rabbit Hole: Child and Family Experiences of Pediatric Hematopoietic Stem Cell Transplant
Authors: West Christina H. , Dusome Debra L. , Winsor Joanne , Rallison Lillian B.
Published: April 2020

Pediatric hematopoietic stem cell transplant (HSCT) is an intensive treatment that can be life-threatening. All family members experience distress. We conducted a grounded theory study using a family systems-expressive arts framework to develop a theoretical understanding of the family experience of HSCT. Six families (15 family members) participated in two interviews, drew an image, and were guided through a “dialoguing with images” process. Participants did not always perceive HSCT as an experience they had lived as a family and were surprised to hear other family members’ experiences. While one mother drew, she suddenly understood it was not only her ill child, but the entire family who had “fallen down the rabbit hole.” The family experience of HSCT is described across (a) the pre-HSCT trajectory, (b) family fragmentation (hospitalization), and (c) family reintegration. We identified a critical need for targeted family intervention during the transition into HSCT, throughout and following hospitalization.
When Does Differential Item Functioning Matter for Screening? A Method for Empirical Evaluation
Authors: Gonzalez Oscar , Pelham William E.
Published: April 2020

When items in a screening measure exhibit differential item functioning (DIF) across groups (e.g., males vs. females), DIF might affect which individuals are “caught” in the screening. This phenomenon is common, but DIF detection procedures do not typically provide guidance on whether the presence of DIF will meaningfully affect screening accuracy. Millsap and Kwok proposed a method to quantify the impact of DIF on screening accuracy, but their approach had limitations that prevent its use in scenarios where items are discrete. We extend the Millsap and Kwok procedure to accommodate discrete items and provide R functions to apply the procedure to the user’s own data. We illustrate our approach using published screening information and evaluate the proposed methodology with a small simulation study. Overall, we encourage researchers to use empirical methods to evaluate the extent to which the presence of DIF in a screening measure materially affects screening performance.
The prognostic values of systemic immune-inflammation index and derived neutrophil-lymphocyte ratio in EGFR-mutant advanced non-small cell lung cancer
Authors: Yucel Sebnem , Bilgin Burak
Published: April 2020

Introduction

Targeted therapy is the main treatment option for oncogene-addicted non-small cell lung cancer (NSCLC). It is known that inflammation can affect survival. Therefore, we aimed to evaluate the effect of host inflammation on survival and treatment outcome by using the derived neutrophil-lymphocyte ratio (dNLR) and systemic immune-inflammation index (SII).

Material and methods

The advanced epidermal growth factor receptor mutant NSCLC patients diagnosed between 2014 and 2019 were included. SII and dNLR were calculated from pretreatment blood samples. The estimated cutoff for SII and dNLR were 640 and 2, respectively. Progression-free survival and overall survival were calculated by using the Kaplan–Meier test.

Results

One hundred thirty six patients enrolled in the study. Of the total patients, 34.6% and 65.4% were SII-low and high, respectively. In addition, 58.1% and 41.9% of the patients were dNLR-low and high groups, respectively. The progression-free survival was better in low SII (22.4 vs. 13.01 months, HR: 0.50; 95% CI 0.32–0.80; P: 0.003) and low dNLR groups (16.9 vs. 13.01 months, HR, 0.58; 95% CI 0.38–0.88; P: 0.011). The overall survival was also significantly longer in SII-low and dNLR-low groups (32.4 vs. 20.4 months; HR, 0.47; 95% CI 0.27–0.81; P: 0.005 for SII and 32.4 vs. 18.4 months HR: 0.40; 95% CI 0.24–0.66; P < 0.001 for dNLR).

Conclusion

Based on the results of our study, both SII and dNLR can be routinely used as the simple, inexpensive and easily assessable prognostic markers in oncogene-addicted NSCLC.
Alexithymia, Prior Trauma, Alcohol Use, and Sexual Aggression Perpetration: A Cross-Cultural Comparison of a Moderated Mediation Model
Authors: Hawkins Lindsey G. , Mullet Natira , Tuliao Antover P. , Gudenrath Travis , Holyoak Derek , Landoy Bernice Vania N. , Klanecky Alicia K. , McChargue Dennis E.
Published: April 2020

In this study, we examined the relationships between prior trauma, alexithymia, and sexual aggression perpetration among 610 U.S. college students and 107 college students from the Philippines utilizing a cross-sectional retrospective design. We tested a moderated mediation model with alexithymia as the mediator between prior trauma and sexual aggression perpetration, and alcohol use as a moderator of the alexithymia–sexual aggression link. Moreover, given that cultural norms may influence these relationships, we also examined the structural invariance of the proposed moderated mediation model. Path analyses and multiple group analysis were used to examine the moderated mediation model, and examine model differences between samples. We did not find evidence for alexithymia as a mediator, but there was a significant interaction between alcohol use severity and alexithymia on sexual aggression perpetration across both samples. Alexithymia is a key variable in understanding the alcohol use–sexual aggression perpetration relationship. Clinical implications and recommendations for future research are also discussed.
Little “we’s”: How common identities improve behavior differently for ethnic majority and minority children
Authors: Guerra Rita , Waldzus Sven , Lopes Diniz , Popa-Roch Maria , Lloret Beatriz , Gaertner Samuel L.
Published: April 2020

This field experiment tested whether inducing common inclusive representations (i.e., one group, dual identity) during contact influences intergroup relations differently for ethnic majority and minority children by changing their metaperceptions and intergroup emotions differently. White ( N = 113) and Black ( N = 111) 8- to 10-year-old children were exposed to interactive mixed-ethnicity sessions in schools emphasizing either categorization as one group (national group), dual identity (national group with ethnic subgroups), or two ethnic groups. Overall, as predicted, for White children, one-group, but not dual-identity perceptions, improved behavioral intentions by influencing metaperceptions. For Black children, dual-identity, but not one-group, perceptions improved behavioral intentions through metaperceptions. Contrary to the expected, both dual-identity and one-group perceptions were associated with White and Black children’s intergroup emotions.
Media pushing for political transformation: A comparative analysis of issue contestation in Poland before 1989 and Egypt before 2011
Authors: Richter Carola , Dupuis Indira , Badr Hanan
Published: April 2020

This article compares two cases of media reporting on the crucial contesting issue of brutality carried out by security forces that proved to be relevant for delegitimizing the regimes in both Poland in 1989 and Egypt in 2011. We show that, despite the different technological infrastructure available and the distinct institutionalization of the political and media systems, we can observe similar mechanisms of mass media communication unfolding around a contesting issue that shook the pillars of moral legitimacy of the regimes, thus paving the way for political transformation.
Gratitude Increases the Motivation to Fulfill a Partner’s Sexual Needs
Authors: Brady Ashlyn , Baker Levi R. , Muise Amy , Impett Emily A.
Published: April 2020

Maintaining sexual satisfaction is a critical, yet challenging, aspect of most romantic relationships. Although prior research has established that sexual communal strength (SCS)—i.e., the extent to which people are motivated to be responsive to their partner’s sexual needs—benefits romantic relationships, research has yet to identify factors that promote SCS. We predicted that gratitude would increase SCS because gratitude motivates partners to maintain close relationships. These predictions were supported in three studies with cross-sectional, longitudinal, and experimental methods. Specifically, experiencing and receiving expressions of gratitude were associated with greater SCS. These studies are the first to investigate the benefits of gratitude in the sexual domain and identify factors that promote SCS. Together, these results have important implications for relationship and sexual satisfaction in romantic relationships.
Do Links Between Personality and Life Outcomes Generalize? Testing the Robustness of Trait–Outcome Associations Across Gender, Age, Ethnicity, and Analytic Approaches
Authors: Soto Christopher J.
Published: April 2020

The Big Five personality traits have been linked with a broad range of consequential life outcomes. The present research systematically tested whether such trait–outcome associations generalize across gender, age, ethnicity, and analytic approaches that control for demographic and personality covariates. Analyses of nationally representative samples from the Life Outcomes of Personality Replication project ( N = 6,126) indicated that (a) most trait–outcome associations do generalize across gender, age, and ethnicity; (b) controlling for overlap between personality traits substantially reduces the strength of many associations; and (c) several dozen trait–outcome associations proved highly generalizable across all analyses. These findings have important implications for evaluating the robustness of the personality–outcome literature, updating the canon of established trait–outcome associations, and conducting future research.
A non‐selective endothelin receptor antagonist bosentan modulates kinetics of bone marrow‐derived cells in ameliorating pulmonary hypertension in mice

Published: April 2020

The aim of this study was to investigate whether a dual endothelin receptor antagonist bosentan modulates the kinetics of bone marrow‐derived stem cells in inhibiting the development of pulmonary hypertension. Bone marrow chimeric mice, transplanted with enhanced green fluorescent protein (eGFP)‐positive bone marrow mononuclear cells, were exposed to hypobaric hypoxia or kept in the ambient air, and were daily treated with bosentan sodium salt or saline for 21 days. After the treatment period, right ventricular pressure was measured and pulmonary vascular morphometry was conducted. Incorporation of bone marrow‐derived cells was analyzed by immunohistochemistry. Gene expression and protein level in the lung tissue were evaluated by quantitative real‐time PCR and western blotting, respectively. The results showed that, in hypoxic mice, right ventricular pressure and the percentage of muscularized vessel were increased and pulmonary vascular density was decreased, each of which was reversed by bosentan. Bone marrow‐derived endothelial cells and macrophages in lungs were increased by hypoxia. Bosentan promoted bone marrow‐derived endothelial cell incorporation but inhibited macrophage infiltration into lungs. Quantitative real‐time PCR analysis revealed that interleukin 6, stromal cell‐derived factor‐1, and monocyte chemoattractant protein‐1 were upregulated by hypoxia, in which interleukin 6 and monocyte chemoattractant protein‐1 were downregulated and stromal cell‐derived factor‐1 was upregulated by bosentan. Protein level of endothelial nitric oxide synthase (eNOS) in the whole lung was significantly upregulated by hypoxia, which was further upregulated by bosentan. Bosentan modulated kinetics of bone marrow‐derived ECs and macrophages and related gene expression in lungs in ameliorating pulmonary hypertension in mice. Altered kinetics of bone marrow‐derived stem cells may be a novel mechanism of the endothelin receptor blockade in vivo and confer a new understanding of the therapeutic basis for pulmonary hypertension.
Market Orientation, Service Quality Perception, and Customer Satisfaction: The Role of Market-sensing Capabilities
Authors: Amangala Emmanuel A. , Wali Andy Fred
Published: April 2020

This article examines the relationship between market orientation, customers’ perception of firms’ service quality (SQ), and their satisfaction in the Nigeria banking sector. The Expectancy Confirmation Theory (ECT) was adopted to shape this study. The population of this study was employees and customers of Nigerian money deposit banks, and specifically, the survey approach was employed using the quantitative paradigm. We employed simple random sampling technique to select employees and customers from each of the 21 banks making a total of 594 samples, and, thereafter, questionnaires were distributed to customers and employees in the banking hall with the permission of banks. Simple linear and hierarchical regressions were used to test our formulated hypotheses and the study analysis found a positive and significant relationship between market orientation and SQ perceptions of customers. Also, market orientation on customer satisfaction (CSAT) is found to be positive and significant. Market-sensing capabilities were found to have significant but weak effect on the relationship between market orientation and SQ perceptions. Market-sensing capabilities were found to have no effect on the relationship between market orientation and CSAT. In other words, market-sensing capabilities were found not to be a moderator of the relationship between market orientation and CSAT.
Geriatric Opioid Harm Reduction: Interprofessional Student Learning Outcomes
Authors: Zanjani Faika , Brooks Marshall , Waters Leland , Parsons Pamela , Slattum Patricia
Published: April 2020

Objective: Opioid harm reduction is increasingly important in the care of the older adults, who are at higher risk for negative opioid-related outcomes due to high prevalence of pain, multimorbidity, polypharmacy, and age-changes in metabolism. Our project aims to develop, implement, and evaluate an interprofessional opioid harm reduction service training. Method: This evaluation occurs in context of the Richmond Health and Wellness Program (RHWP), a community-based interprofessional wellness care coordination equity initiative, within buildings designated for low-income and disabled older adults. The geriatric opioid harm reduction training was delivered online and inperson, and followed up with case-discussions and practice. Findings: Pre ( n = 69)/post ( n = 62) student assessments indicated that after the training, there was an increase in knowledge. At follow-up, 60% recognized tramadol as an opioid, 50% at baseline. About 97% correctly indicated that MME represents morphine milligram equivalent, 80% at baseline. About 93% indicated that 50 MME level greatly increases opioid overdose risk, 62% at baseline. Only 20%, change from 60% at baseline, reported not being able to calculate MME at post assessment. Conclusion: Findings indicate that geriatric opioid harm reduction training within community-based wellness care coordination is feasible. Future works need to explore the impact on student practice in clinical settings and resident health.

An interprofessional cohort analysis of student interest in medical ethics education: a survey-based quantitative study
Authors: DeFoor Mikalyn T. , Chung Yunmi , Zadinsky Julie K. , Dowling Jeffrey , Sams Richard W.
Published: April 2020

Background

There is continued need for enhanced medical ethics education across the United States. In an effort to guide medical ethics education reform, we report the first interprofessional survey of a cohort of graduate medical, nursing and allied health professional students that examined perceived student need for more formalized medical ethics education and assessed preferences for teaching methods in a graduate level medical ethics curriculum.

Methods

In January 2018, following the successful implementation of a peer-led, grassroots medical ethics curriculum, student leaders under faculty guidance conducted a cross-sectional survey with 562 of 1357 responses received (41% overall response rate) among students enrolled in the School of Medicine, College of Nursing, Doctor of Physical Therapy and BS/(D) MD Professional Scholars programs at The Medical College of Georgia at Augusta University. An in person or web-based questionnaire was designed to measure perceived need for a more in-depth medical ethics curriculum.

Results

The majority of respondents were female (333, 59.3%), white (326, 58.0%) and mid-20s in age (340, 60.5%). Almost half of respondents (47%) reported no prior medical ethics exposure or training in their previous educational experience, while 60% of students across all degree programs reported an interest in more medical ethics education and 92% noted that an understanding of medical ethics was important to their future career. Over a quarter of students (28%) were interested in pursuing graduate-level training in medical ethics, with case-based discussions, small group peer settings and ethics guest lectures being the most desired teaching methods.

Conclusions

The future physician, nursing and physical therapist workforce in our medical community demonstrated an unmet need and strong interest for more formal medical ethics education within their current coursework. Grassroots student-driven curricular development and leadership in medical ethics can positively impact medical education. Subsequent integration of interprofessional training in medical ethics may serve as a vital curricular approach to improving the training of ethically competent healthcare professionals and overcoming the current hierarchical clinical silos.
Evidence for eosinophil and IL-17 mediated inflammation in allergic rhinitis
Authors: Amin Kawa , Issa Sulaf Mosa , Ali Kosar Mohammad , Aziz Muaid Ismiel , Hama Amieen Huner Mohamed , Bystrom Jonas , Janson Christer
Published: April 2020

Background

The aim was to determine the level of inflammatory cytokines, eosinophil cationic protein and IgE in allergic rhinitis (AR) patients.

Subjects and methods

Blood samples were taken from 88 AR patients and 88 healthy controls (HC). Each sample was analysed for eosinophil counts by flow cytometry, IgE by ECLIA, ECP, IL-17, and IL-33 by using ELISA test.

Results

There was no significant difference between AR patients and the control group in age and gender. Levels of eosinophils, IgE, ECP, IL-17, IL-33 and the total symptom scores were significantly higher in AR patients than the HC (P = 0.0001). Serum ECP correlated with IL-17 (P = 0.041, r = 0.42), IL-33 (P = 0.0001, r = 080), and IgE levels (P = 0.017, r = 0.45) in the R patients. There was no correlation between IL-17 and IL-33. There was a correlation between symptom scores and eosinophils (P = 0.026, r = 0.52), and IgE (P = 0.001, r = 0.60) in the patients. No correlation was observed between symptom scores and ECP, IL-17, and IL-33 in the AR patient.

Conclusions

Patients with AR have significant higher serum levels of ECP, IL-17, and IL-33 than healthy controls. This indicates that these markers could be used to in order to diagnose AR and to monitor disease. Inhibitory molecules to IL-17 and IL-33 may be considered as novel treatment strategies.
Low-dose human menopausal gonadotrophin versus natural cycles in intrauterine insemination for subfertile couples with regular menstruation
Authors: Li Sichen , He Yuxia , Cao Mingzhu , Liu Hanyan , Liu Jianqiao
Published: April 2020

Background

Women with irregular menstruation should be considered to benefit from the ovarian stimulation. However, most literature did not separate ovulatory disorders from normal menstrual cycles. Our purpose was to assess the superiority of ovarian mild stimulation compared with the natural cycle in IUI for subfertile couples when the women with regular menstruation.

Methods

A retrospective study in a single medical center in which 2413 couples with 3573 IUI cycles were studied from 2013 to 2018. The results of IUI in natural cycles versus low-dose HMG induced cycles were analyzed.

Results

For young women (age < 35 years) with normal menstrual cycle, HMG induced ovulation combined with IUI can improve clinical pregnancy outcome (13.55% in two follicular induced cycles vs. 7.23% in natural cycles, p < 0.01); even if only one follicle was induced, the clinical pregnancy rate was increased to 10.32% (p < 0.01). When two growth follicles were induced in HMG cycles, a remarkable improvement of the live birthrate (10.28% vs. 5.91% in natural cycles, p < 0.05) was noted. Simultaneously, twin pregnancy rates were increased to 20.69% (p < 0.01). Twin pregnancies showed significantly increased risk of both ectopic pregnancy and preterm birth (p = 0.00 for both). For advanced women (age ≥ 35 years) with regular menstrual cycle, ovulation induction didn’t improve clinical pregnancy and live birthrates, while age was the only relevant factor.

Conclusions

Combining HMG induced ovulation and IUI can improve pregnancy outcome in young women with normal menstrual cycles. 1–2 follicles with diameter ≥ 14 mm served as the purpose of ovulation induction. Further, both twin and ectopic pregnancy rate in HMG cycles with two growth follicles were significantly higher than those in natural cycles were. Therefore, doctors must evaluate the risk before making choices and inform the patients to achieve the best results. For advanced women with normal menstrual cycles, natural IUI cycles were optional.

Published: April 2020

Objectives:

The aim of this study was to establish diagnostic reference levels (DRLs) in the field of dental maxillofacial and ear-nose-throat (ENT) practices using cone beam CT (CBCT) in Switzerland.

Methods:

A questionnaire was sent to owners of CBCTs in Switzerland; to a total of 612 institutions. The answers were analyzed for each indication, provided that enough data were available. The DRLs were defined as the 75th percentile of air kerma product distribution (PKA).

Results:

227 answers were collected (38% of all centers). Third quartile of PKA values were obtained for five dental indications: 662 mGy cm² for wisdom tooth, 683 mGy cm² for single tooth implant treatment, 542 mGy cm² for tooth position anomalies, 569 mGy cm² for pathological dentoalveolar modifications, and 639 mGy cm² for endodontics. The standard field of view (FOV) size of 5 cm in diameter x 5 cm in height was proposed.

Conclusions:

Large ranges of FOV and PKA were found for a given indication, demonstrating the importance of establishing DRLs as well as FOV recommendations in view of optimizing the present practice. For now, only DRLs for dental and maxillofacial could be defined; because of a lack of ENT data, no DRL values for ENT practices could be derived from this survey.
Effect of blood pressure on stroke severity and outcomes in acute cases
Authors: Kench Charles Albert
Published: April 2020

Background:

Stroke results in impairment of cerebral autoregulation. Systemic blood pressure (BP), whether low or high, may affect cerebral blood flow and cause damage to brain tissue, so is important in the context of stroke. Effective management of BP may result in less severe strokes and better outcomes for patients.

Methods:

A literature search was performed to answer the research question, using the CINAHL Complete and MEDLINE Complete databases. Inclusion and exclusion criteria were applied. Full texts were reviewed for eligibility and 15 quantitative articles were selected and discussed.

Results:

Fifteen international quantitative primary research articles were selected and grouped into four themes: admission blood pressure; BP indexes/BP variability; active treatment of BP; and prehospital care. The articles were randomised controlled trials, cohort studies and one post-hoc analysis.

Conclusion:

In patients with acute ischaemic stroke (AIS), systolic BP in the 140–160 mmHg range on admission to hospital is associated with higher rates of positive outcome and lower stroke severity. BP-lowering therapy in AIS is safe and does not affect stroke severity, but also does not alter patient outcome. In the context of intracerebral haemorrhage (ICH), intensive BP-lowering therapy to a target of 140 mmHg and maintenance of this value for 7 days produces high rates of positive long-term outcomes in terms of quality of life and Modified Rankin Scale scores. Furthermore, early initiation of BP management, namely in the prehospital environment, is beneficial. These results provide evidence that antihypertensive treatment should be provided in the prehospital environment, and support early administration of treatment to reduce systolic BP to a target of 140 mmHg, which is a beneficial value for patients experiencing ICH and AIS.
Improving the political judgement of citizens: why the task environment matters
Authors: Leruth Benjamin , Stoker Gerry
Published: April 2020

Internal political efficacy (that is, beliefs about one’s ability to process and participate effectively in politics) is known to be shaped by factors such as levels of interest in politics, trust in institutions and awareness of political developments and debates. In this article, we show that the task environment also has an impact on internal political efficacy, and that little research has been done on this issue. We draw on data from focus groups in Australia, where citizens were asked to make political judgements in contrasting task environments: state elections and the 2017 same-sex marriage plebiscite. We examine four features of task environments: framing choice; issue content; the nature of available cues; and whether the task environment stimulates cognitive effort. We conclude that concerns about the internal political efficacy of voters should be addressed by exploring how the task environment created for political choice might be made more amenable in order to improve the political judgement of citizens.
Excitation of graphene surface plasmons polaritons by guided-mode resonances with high efficiency
Authors: Ren Yuxiang , Guo Xuguang , Zhang Guixue , Balakin Alexey V. , Shkurinov Alexander P. , Yu Anqi , Zhu Yiming
Published: April 2020

An Otto-like configuration for the excitation of graphene surface plasmon polaritons (GSPPs) is proposed. The configuration is composed of a metallic grating-dielectric-waveguide structure and a monolayer graphene with a subwavelength vacuum gap between them. The evanescent field located at the bottom surface of the dielectric waveguide corresponding to grating-coupled guided-mode resonances (GMRs) is utilized to efficiently excite the highly conﬁned GSPPs. The finite difference time domain method is used to investigate the behaviors of the GMR-GSPP hybrid modes. The dispersion relations of GMRs and GSPPs are calculated and the numerical results further identify the excitation of GMR-GSPP hybrid modes. By changing the gap between the graphene layer and the bottom of the dielectric waveguide and the Fermi energy of graphene, the resonant frequencies of GMR-GSPP hybrid modes can be continuously tuned. When the optimized excitation condition is satisfied, the maximum energy enhancement factor in the gap can reach about 500 at the resonant frequencies. The proposed structure can be used to realize highly sensitive, compatible with planar fabrication technology, and electrically (mechanically) tunable sensors.
Visual seduction: Eroticism in surrealistic art photography and postmodern fashion photography
Authors: Jestratijevic Iva
Published: April 2020

Surrealistic art photography reveals eroticism and nudity as something that both fascinates and agitates, compelling the audience to pay attention, willingly or reluctantly. Undoubtedly, for surrealistic artists the sphere of fantasy and sexual sensation emerge as a source of pleasure and aesthetic sensation. Surrealistic fantasies, dreams and human sexuality have merged with elements of art and porn culture to create hybrid visual forms and postmodern fashion photography is certainly among them. Unlike surrealistic art photography that serves as an emancipatory tactic or as a transgressive act of provoking the public, postmodern fashion photography utilizes eroticism as an expression or vestige of perverse enjoyment. Perversion in the eroticized postmodern context holds somewhat particular meaning. Desire is operationalized without restrictions, appears everywhere while losing its imaginary. Hence, visual seduction is a never-ending game between seducers and the seduced. In light of a growing interest in understanding photography, and visual culture, this article examines how eroticism is constructed through surrealistic photographed content, and it explores the implication of this for further study of postmodern fashion photography. Conceptually, and methodologically, this article draws on semiotics (Roland Barthes), and discursive analysis, including psychoanalytic (Sigmund Freud), and representational theory and practice (Laura Mulvey, Stuart Hall and Jean Baudrillard).
Tailoring a method: Adaptation of design thinking to transmedia journalism
Authors: Gürsoy Dilek
Published: April 2020

Design thinking is not an alien concept to the field of transmedia storytelling. However, the distinction between fictional and non-fictional approaches to transmedia production indicates that there is an insufficiency in existing production methods, especially when transmedia news stories are taken into consideration. The lack of journalism perspective in existing transmedia production approaches calls for reconsideration of these methods. Therefore, this research proposes a toolkit which draws out the significance of design thinking for the practice of transmedia journalism that rests upon a complex, collective and human-centred production. The toolkit is later evaluated by a one-day workshop on the grounds of collectivity in process, sensibility to content, creativity in outcome and simplicity in design. Consequently, the research shows that the proposed design thinking toolkit serves as an effective comprehension, cooperation, adaptation, distinction and education tool for the field of transmedia journalism.
‘Intuition as Method’ as an approach for information design
Authors: Özmen Melike
Published: April 2020

Information design is an interdisciplinary field of research and practice. According to International Institute for Information Design (IIID), information design is the defining, planning and shaping of the contents of a message and the environments, with the intention to satisfy the information needs of the intended recipients. Although IIID’s definition indicates a relationship between information, information designer, the environment, and the users, the definition lacks the roles of the users’ participation and the interaction amongst information, the environment, and the users in the process of designing information. It is possible to define three accounts in the design process. Information design approaches often impose a hierarchical relationship between these three accounts. Bergson’s ‘Intuition as Method’ and its rules can be adapted to bring these three accounts together on a horizontal formation and give the roles of these three separate accounts to the designer instead of applying a hierarchical structure in the design process.
A multidimensional perspective on lifestyle analysis in Turkey
Authors: Öztunç Müge
Published: April 2020

Lifestyle segmentation has been prominently used in marketing and communication to define consumption patterns and marketing communication processes. This article underlines the significance of a multidimensional approach to lifestyle analysis. Bourdieu’s statistical technique of ‘multiple correspondence analysis’ permits to find unexpected dimensions and offer visual representation of the relationships between categories. This technique has been used to re-analyse Konda’s 2008 Lifestyle Research data, which was one of the most influential and widely circulated lifestyle segmentation research papers of its time, that introduced the categories of ‘anxious-moderns’ and ‘conservative-moderns’. The patterns identified through multidimensional analysis have been used in discourse analysis that permit to interpret the complex and heterogeneous nature of social dynamics.
The politics of self-reflexivity in ethnography
Authors: Erkonan Sahika
Published: April 2020

This short commentary aims to describe the role of political subjectivity and the researcher’s memory in fieldwork by focusing on a self-reflective account of my ethnographic fieldwork. This reflection comes after two years of ethnographic inquiry into sensory experience and observation of how memory is performed in relation to personal photographs and objects. It is part of an ongoing Ph.D. thesis about the post-memories of Armenian Genocide descendants in the diaspora, where I seek to understand how they remember the past in the present by observing their sensory engagement with the past. As well as this, the fieldwork shows the necessity of auto-ethnographic inquiry of the researcher, given that I am Turkish. This commentary ultimately asks what the role is of political subjectivity in ethnographic fieldwork, thinking especially of visual mediation in the diaspora.
The power of the pen(cil): Enduring validity in technology-dominated design education
Authors: Verma Amitabh
Published: April 2020

The recent marginalization of long-established manual graphic traditions by technological alternatives has precipitated wide-ranging consequences for design education in diverse contexts and specializations. In this article, I analyse this progression as situated within the discipline of landscape architecture, advocating for a curricular reformation to reprioritize manual graphics as a pivotal element in design education. From my vantage point at the intersection of professional practice, pedagogy and research, I summarize this development within the specific arena of landscape architecture education. Prominent issues of concern and implications are identified, followed by articulation of remedial strategies appropriate to current circumstances.
The acute time course of muscle and tendon tissue changes following one minute of static stretching
Authors: Konrad Andreas , Tilp Markus

The purpose of this study was to investigate the time course of the changes of various muscle and tendon mechanical properties and the function responses of the plantar flexor muscles following 1 min of static stretching.Twenty-five healthy volunteers were assigned into a static stretching group or a control group. The static stretching group was tested with three different rest times (0 min,20 min,40 min) after 2x30s of stretching. Controls were tested before and after a control period (10 min) without stretching. Dorsiflexion range of motion (RoM), passive resistive torque (PRT), and maximum voluntary contraction (MVC) were measured with a dynamometer. Ultrasonography of the medial gastrocnemius (GM) muscle-tendon junction (MTJ) displacement allowed us to determine the length changes in the tendon and muscle, respectively, and hence to calculate their stiffness.Following the stretching, we observed a significant increase in RoM directly following the stretching, 20 min post-stretching, and 40 min post-stretching. However, no changes were found in other functional parameters (PRT, MVC) or structural parameters (muscle and tendon stiffness). No changes were detected in any variable in the control group.We conclude that a static stretching exercise of 2x30s increases the RoM for at least 40 min. However, this gain in RoM is not accompanied with more compliant muscle and/or tendon tissue, suggesting that 60s of static stretching might not be stimulus enough to induce changes in the muscle-tendon structure. Hence, we speculate that other factors, such as increased stretch tolerance, might be responsible for the changes in the RoM observed in the present study.

The present study elucidates the effect of matrix priming with vermicompost (VCP) on germination and seedling emergence of two onion seed lots under drought, salt and temperature stress conditions. Seeds treated with water was considered as hydropriming (HP) and untreated (NP) seeds
were taken as control. Treated and untreated seeds were exposed to different levels of drought (10 and 15% PEG), salt (50 and 100 mM NaCl) and temperature (30 and 35°C) stresses. Priming with vermicompost improved the performance of onion seed as indicated by higher germination and seedling
growth under stress conditions. Catalase, superoxide dismutase and ascorbate peroxidase activities were found to be significantly (P < 0.05) higher in the vermicompost treated seeds than hydroprimed and untreated seeds.

We tested for dormancy in three species of Acronychia (Rutaceae) occurring in the rainforest in eastern Australia, A. imperforata, A. laevis and A. oblongifolia, by incubating fresh intact seeds on 0.8% water agar for one month at 25/10°C. Four different
techniques were then tested for their effect on dormancy: (i) incubation of intact seeds on agar incorporating gibberellic acid (GA3); (ii) seed coat removal (decoating); (iii) scarification near the radicle emergence point (scarification-emergence point); and (iv) scarification
opposite the radicle emergence point (scarification-back). Imbibition tests were performed to determine whether dormancy was due to an impermeable seed coat. Germination differed among treatments, but all three species showed a similar pattern. Intact seeds showed < 6% germination after
one month indicating the presence of dormancy. Highest germination (> 65%) was observed following scarification-emergence point treatment. Seed coat removal also resulted in increased germination (40-47%), in comparison with intact seeds, but GA3 and scarification-back treatments
did not (< 12%). Though the seedcoats of all species were permeable, increased germination responses to decoating and scarification-emergence point treatments suggest scarification is required to clear the radicle emergence point. This may be a useful dormancy-breaking technique for Acronychia
spp. and may be suitable for related Rutaceae species.

Metastatic colonization, whereby a disseminated tumor cell is able to survive and proliferate at a secondary site, involves both tumor cell-intrinsic and -extrinsic factors. To identify tumor cell-extrinsic (microenvironmental) factors that regulate the ability of metastatic tumor cells to effectively colonize a tissue, we performed a genome-wide screen utilizing the experimental metastasis assay on mutant mice. Mutant and wildtype (control) mice were tail vein-dosed with murine metastatic melanoma B16-F10 cells and 10 days later the number of pulmonary metastatic colonies were counted. Of the 1,300 genes/genetic locations (1,344 alleles) assessed in the screen 34 genes were determined to significantly regulate pulmonary metastatic colonization (15 increased and 19 decreased; P < 0.005 and genotype effect <-55 or >+55). While several of these genes have known roles in immune system regulation (Bach2, Cyba, Cybb, Cybc1, Id2, Igh-6, Irf1, Irf7, Ncf1, Ncf2, Ncf4 and Pik3cg) most are involved in a disparate range of biological processes, ranging from ubiquitination (Herc1) to diphthamide synthesis (Dph6) to Rho GTPase-activation (Arhgap30 and Fgd4), with no previous reports of a role in the regulation of metastasis. Thus, we have identified numerous novel regulators of pulmonary metastatic colonization, which may represent potential therapeutic targets.
