The C-terminal domain of Kv1.3 regulates functional interactions with the KCNE4 subunit
Authors: Solé Laura , Roig Sara R. , Vallejo-Gracia Albert , Serrano-Albarrás Antonio , Martínez-Mármol Ramón , Tamkun Michael M. , Felipe Antonio
Published: October 2016

The voltage-dependent K+ channel Kv1.3 (also known as KCNA3), which plays crucial roles in leukocytes, physically interacts with KCNE4. This interaction inhibits the K+ currents because the channel is retained within intracellular compartments. Thus, KCNE subunits are regulators of K+ channels in the immune system. Although the canonical interactions of KCNE subunits with Kv7 channels are under intensive investigation, the molecular determinants governing the important Kv1.3– KCNE4 association in the immune system are unknown. Our results suggest that the tertiary structure of the C-terminal domain of Kv1.3 is necessary and sufficient for such an interaction. However, this element is apparently not involved in modulating Kv1.3 gating. Furthermore, the KCNE4-dependent intracellular retention of the channel, which negatively affects the activity of Kv1.3, is mediated by two independent and additive mechanisms. First, KCNE4 masks the YMVIEE signature at the C-terminus of Kv1.3, which is crucial for the surface targeting of the channel. Second, we identify a potent endoplasmic reticulum retention motif in KCNE4 that further limits cell surface expression. Our results define specific molecular determinants that play crucial roles in the physiological function of Kv1.3 in leukocytes.

Published: October 2016

By filtering relevant sensory inputs and initiating stress responses, the brain is an essential organ in stress coping and adaptation. However, exposure to chronic or repeated stress can lead to allostatic overload, where neuroendocrinal and behavioral reactions to stress become maladaptive. This work examines forebrain mechanisms involved in allostatic processes in teleost fishes. Plasma cortisol, forebrain serotonergic (5-HTergic) neurochemistry and mRNA levels of corticotropin-releasing factor (CRF), CRF binding protein (CRFBP), CRF receptors (CRFR1 and CRFR2), mineralocorticoid receptor (MR), glucocorticoid receptors (GR1 and GR2), and 5-HT1A receptors (5-HT1Aα and 5-HT1Aβ) were investigated at 1 h before and 0, 1 and 4 h after acute stress, in two groups of rainbow trout held in densities of 25 and 140 kg m−3 for 28 days. Generally, being held at 140 kg m−3 resulted in a less pronounced cortisol response. This effect was also reflected in lower forebrain 5-HTergic turnover, but not in mRNA levels in any of the investigated genes. This lends further support to allostatic load as a situation where fish cannot mount a proper cortisol response to an acute stressor, and suggests that changes in forebrain 5-HT metabolism is involved in allostatic processes in fish. Independent of rearing densities, mRNA levels of 5-HT1Aα and MR were down regulated 4 h post stress compared to values 1 h post stress, suggesting that these receptors are under feedback control and take part in the down regulation of the hypothalamic-pituitary-interrenal (HPI) axis after an acute stressor.
VISIT-TS: A multimedia tool for population studies on tic disorders

Published: October 2016

Population-based assessment of Tourette syndrome (TS) and other tic disorders produces a paradox. On one hand, ideally diagnosis of tic disorders requires expert observation. In fact, diagnostic criteria for TS explicitly require expert assessment of tics for a definite diagnosis. On the other hand, large-scale population surveys with expert assessment of every subject are impracticable. True, several published studies have successfully used expert assessment to find tic prevalence in a representative population (e.g. all students in a school district). However, extending these studies to larger populations is daunting.

We created a multimedia tool to demonstrate tics to a lay audience, discuss their defining and common attributes, and address features that differentiate tics from other movements and vocalizations. A first version was modified to improve clarity and to include a more diverse group in terms of age and ethnicity. The result is a tool intended for epidemiological research. It may also provide additional benefits, such as more representative minority recruitment for other TS studies and increased community awareness of TS.

Published: October 2016

Cel pracy

W artykule analizie poddano jakość życia kobiet z rakiem piersi, ze szczególnym uwzględnieniem wskaźników satysfakcji seksualnej, perspektyw na przyszłość oraz obrazu ciała w zależności od zastosowanej metody leczenia operacyjnego.

Metoda

Do badania zakwalifikowano 42 kobiety w wieku 35 do 70 lat, 3 miesiące po przebytym leczeniu chirurgicznym z powodu wczesnego raka piersi, poddanych chemioterapii uzupełniającej. Jako narzędzia badawcze zastosowano dwa kwestionariusze EORTC: QLQ-C30 i BR23 oraz kwestionariusz funkcji seksualnych: PL-FSFI.

Wyniki

Nie wykazano istotnej różnicy w zakresie ogólnej jakości życia w zależności od rodzaju zabiegu chirurgicznego. Największe dolegliwości w zakresie dolegliwości miejscowych zgłaszały chore pooddane operacji oszczędzającej (=BCT) z limfadenektomią pachową. U kobiet poddanych mastektomii wykazano wyższy poziom funkcjonowania poznawczego, natomiast większe nasilenie systemowych objawów ubocznych w porównaniu do pacjentek po BCT. Chore u których zabieg dotyczył piersi prawej raportowały więcej problemów w funkcjonowaniu seksualnym (p=0,034). W analizie regresji wielorakiej wykazano dodatnią korelację zmiennej funkcjonowanie emocjonalne z oceną przyszłych perspektyw (p=0,01) oraz oceną obrazu ciała (p=0,007).

Wnioski

Rodzaj techniki operacyjnej nie wpływa na ogólną jakość życia oraz na satysfakcję seksualną operowanych kobiet. Problemy z pamięcią i koncentracją uwagi nie korelują bezpośrednio z nasileniem objawów ubocznych leczenia i jako takie wymagają niezależnej diagnostyki. U pacjentek, u których zabieg dotyczył piersi po stronie ręki prawej (dominującej) należy rozważyć potrzebę konsultacji seksuologicznej. Kobiety z rakiem piersi, u których obserwuje się zaburzenia emocjonalne w okresie 3 miesięcy po zabiegu operacyjnym posiadają zwiększone ryzyko zaburzeń w obrazie ciała jak i w ocenie przyszłych perspektyw.
Inhomogeneous Financial Networks and Contagious Links
Authors: Amini Hamed , Minca Andreea
Published: October 2016

We propose a framework for testing the possibility of large cascades in financial networks. This framework accommodates a variety of specifications for the probabilities of emergence of “contagious links” conditional on a macroeconomic shock, where a contagious link leads to the default of a bank following the default of its counterparty. Under general contagion mechanisms and incomplete information, the financial network is modeled as an inhomogeneous random graph, where the conditional probabilities of having contagious links depend on banks’ characteristics. We give different bounds on the size of the cascade through contagious links and derive testable conditions for this cascade to be small.
Social media practices on Twitter: maximising the impact of cardiac associations
Authors: Gallagher Robyn , Psaroulis Trifon , Ferguson Caleb , Neubeck Lis , Gallagher Patrick
Published: October 2016

Twitter is a social media platform often used by cardiac professional associations to engage and inform their members and the public. However, the effectiveness of the strategy is seldom assessed or published.

Aim:

This study evaluates the Twitter activities of nine cardiac professional associations. Each organisation's purpose and stakeholders were described individually and classified. Extracted Tweets (n=3920) were content-analysed and metrics were determined.

Results:

There was alignment between the associations' mission statements and their Twitter activities. However, most Tweets were one-directional, disseminating research-based evidence/professional education materials and communicating association events and activities, as well as using hashtags to enable searching.

Conclusion:

Social media communication by cardiac professional associations through Tweets is an important activity; however, at present, the use of dialogue and conversations are not fully realised and could be used more strategically.

Authors: Lee Natalie , Wigg Jane , Pugh Stacy , Barclay Janet , Moore Hayley
Published: October 2016

There are many intermittent pneumatic compression devices available for use in the management and adjunct treatment of lymphatic, venous and arterial disease. This article discusses the development of a new advanced pneumatic compression device, the LymphFlow Advance, which can perform focussed treatment on the lymphoedematous area using a variety of different cycles. Case studies with therapist and patient feedback are used to demonstrate the use of the LymphFlow Advance in the lymphoedema clinic, with a discussion of the evidence to underpin recommended treatment regimes.
Chronic oedema: its prevalence, effects and management
Authors: Cooper Garry
Published: October 2016

Ageing affects not only individuals but also society. It occurs throughout the western world. The ageing process may lead to the development of conditions, such as chronic oedema, as well as comorbidities such as osteoarthritis. These comorbidities can make the management of chronic oedema even more difficult. This is an especially important consideration when tailoring individualised care plans, such as exercise, as conditions such as rheumatoid arthritis can limit patients' ability to manage their oedema. Despite challenges, education can improve patient outcomes when evidence-based practice is used.
Choice of planned place of birth for women with diet-controlled gestational diabetes mellitus
Authors: Brown Anna Maria , Rajeswari Devannas , Bowles Angie
Published: October 2016

Background:

Women with diet-controlled gestational diabetes have been excluded from birthing in one midwife-led birth centre due to an assumed risk of complications.

Aims:

This study aimed to examine the rates of adverse outcomes for women diagnosed with gestational diabetes who have controlled their hypoglycaemia through dietary change, but who may be excluded from birthing in a midwife-led centre owing to risk of complications, to identify whether outcomes are the same for these women as for other low-risk women giving birth in one local maternity unit.

Methods:

Retrospective analysis was conducted of data on low-risk women giving birth at a maternity unit in the South East of England to compare the birth outcomes of women with or without gestational diabetes. Data were analysed in Microsoft Excel and presented as descriptive statistics.

Findings:

In 2014, a total of 164 out of 4032 women who gave birth at the maternity unit had gestational diabetes. Among these, 89 were controlled through diet alone. Data for 4 months in 2015 were also examined for 57 women with gestational diabetes.

Conclusions:

The mode of delivery and outcomes for the women in this cohort who remained normoglycaemic have been found to be in line with the general outcomes for all women at this hospital during the study period. The women diagnosed with gestational diabetes but well controlled on diet had similar outcomes to low-risk women giving birth at the maternity unit. The small sample size means further work is needed to confirm the findings, but indicates that the option of using the birth centre may be considered a reasonable alternative for these women.
Should midwives consider associated psychological factors when caring for women who are obese?
Authors: Wahedi Maureen
Published: October 2016

Background:

In the UK, 15.6% of the maternal population are obese (body mass index ≥ 30 kg/m2), posing serious health consequences to the woman and fetus. Current maternal weight management interventions, focusing on healthy diet and exercise, fail to adequately address this problem, which may be attributable to a bidirectional association between maternal obesity and psychological factors not being addressed.

Aims:

The aim of this reflective literature review is to determine whether there is sufficient evidence to suggest that midwives should consider psychological factors when caring for women who are obese.

Methods:

A literature review was undertaken of papers from academic journals, dissertations, theses and professional magazines, published between 2005 and 2015. A total of 529 articles were returned, of which 10 were selected for review.

Findings:

Critical analysis of 10 relevant studies confirms an association between maternal obesity and women's psychological wellbeing. Many midwives are aware of this relationship, but feel they lack the knowledge and interpersonal competence to address such issues.

Conclusions:

Midwives require greater understanding of psychological complexities surrounding pregnancy weight management, and training in person-centred counselling techniques, in order to optimise health outcomes for women and neonates.
Increasing uptake of chlamydia screening in general practice
Authors: Strivens Karen
Published: October 2016

Chlamydia screening rates remain sub-optimal in the UK, but awareness raising using multi-media, plus training and education for clinicians, can improve uptake. Karen Strivens outlines findings of a pilot study to determine practical solutions in general practice.

Chlamydia infection poses a huge challenge to public health and to the NHS, hence current policies to enhance screening in 15–24 year olds, the highest risk group ( Department of Health, 2009 ; National Chlamydia Screening Programme 2012 ; Public Health England, 2014 ). Despite efforts to reduce infection rates through mass media campaigns encouraging routine screening, rates remain sub-optimal and chlamydia infection continues to rise ( NHS Choices, 2010 ; Gobin et al, 2013 ). To address this, a pilot study was undertaken by a large general practice in north west England to improve screening uptake, using a three-pronged approach: raising awareness of chlamydia infection and available screening services via posters and text messages and online; providing practice staff with education and training to encourage uptake of screening in contraceptive and sexual health appointments; and initiating an evening drop-in service. Although the drop-in service did not achieve the anticipated attendance rate, findings highlighted a significant increase in chlamydia screening following the awareness-raising local multi-media campaign and education and training of staff.

Assessment of the needs of student nurses regarding critical thinking in nursing practice
Authors: Pretoruis Louise , Van Dyk Agenes , Small Luis , Amukugo Hans Justus
Published: October 2016

This study involved a quantitative, quasi-experimental and contextual design. The target population for this phase was senior student nurses registered at the University of Namibia, in their fourth year of nursing studies in the training hospitals of Windhoek and Oshakati. A total of 46 fourth-year nursing students, registered at the Faculty of Medical and Health Sciences in the Department of Nursing, were included for phase 1 except for the two students who took part in the pilot study. The students were from both campuses, namely the Windhoek and Oshakati campuses, doing the four-year Diploma in Comprehensive Nursing curriculum, which incorporates the principles of critical thinking. An imaginary case scenario was developed for students to analyse and answer some relevant questions to enable the researcher to determine the level of understanding and integration of critical thinking. In this study each student’s answers were deductively analysed by calculating central values, more specifically the mean for each question, to determine their application of critical thinking skills in the management of a nursing problemThe researcher has, with literature support, arrived at “umbrella” concepts, namely the most important concepts that nurses in Namibia need and without which they cannot practice. These umbrella concepts are to be included in the educational programme.
Paediatric Renal Biopsies in East Bohemia. Single Centre Experience in the Years 1997–2008
Authors: Skálová Sylva , Podhola Miroslav , Rejtar Pavel
Published: October 2016

This report analyses data on 177 renal biopsies (RB) performed in 174 children in the East Bohemian region throughout 1997–2008. The primary aim was to evaluate the diagnostic benefit of the procedure, the secondary aim was to assess the safety of RB and prevalence of clinical complications. The patients’ mean age at the time of RB was 12.77 ± 4.17 years; range 1 to 19 years; male to female ratio 1.17:1. Haematuria was the most common indication for RB. All RBs were performed by a single consultant nephrologist. 27 biopsies in 27 patients (15.3 %) in 1997 were performed under X-ray control, the remaining 150 RB (84.7 %) under ultrasound guidance. The mean annual number of RBs performed in 1997–2001 was significantly higher than in the 2003–2008 period (21.6±5.5 versus 9.9±1.2; p=0.0003). All samples were diagnostic. The mean number of glomeruli was 23.5±11.4 (range 4–55) per sample. The RB resulted in information yielding a definite diagnosis and/or prognosis in 173 children (99.4 %). The most frequent diagnoses were IgA nephropathy (n=41; 23.5 %), mesangioproliferative glomerulonephritis (n=31; 17.8 %) and thin basement membrane glomerulopathy (n=22; 12.6 %). No major complications were encountered and only minor complications occurred in 43 cases (24.2 %), not requiring medical intervention. In conclusion, the present practice of RB in children is safe, with high clinical benefit.

Authors: Halboub Essam , Dhaifullah Essam , Abdulhuq Mahmoud
Published: October 2016

Khat (Catha Edulis Forskal) is widely cultivated in Yemen and East of Africa. The habit of chewing tender leaves and twigs of khat is deep-rooted in Yemen. Our study investigates the chronic khat chewing and smoking effect on oral mucosa. The sample (n=79) consists of two main groups, khat chewers (n=54) and control groups (n=25). Khat chewers group is divided into 4 subgroups according to duration of khat chewing and smoking habit. The control group is divided into 2 subgroups according to smoking habit. Whitening with mild corrugation, frictional keratosis and frictional keratosis with mild or sever corrugation were the clinical findings. One hundred percent of clinical findings were present on buccal mucosa of chewing side of both smokers and non-smokers whatever the duration of khat chewing period. On the vestibular and mucobuccal fold mucosa, (100 % and 73.3 %) and (60 % and 43.7 %) of the khat chewers group had clinical findings on chewing side of smokers and non-smokers according to khat chewing duration respectively. There was clinical relationship between these lesions and khat chewing, but not smoking. Khat chewing causes oral white lesions on the chewing side and it is found that smoking, clinically, does not exacerbate such lesions.

Published: October 2016

We report a case of liver metastasis of lung carcinoma with portal vein tumor thrombus (PVTT). Although the primary lesion of lung tumor remained unchanged, the patient rapidly developed wide-spread metastases and formed PVTT of liver metastasis. The primary lesion showed features of mixed Clara and bronchial surface epithelial cell component type adenocarcinoma with small foci of micropapillary pattern. Micropapillary pattern was observed in the metastatic lesions in the liver and PVTT. Micropapillary pattern lung adenocarcinoma may develop rapid metastases and cause PVTT associated with liver metastasis. We should perform a detailed examination to establish correct diagnosis.

Técnica field in field em planejamentos bidimensionais para irradiação de cérebro total
Authors: Castro André Lima Souza , Campos Tarcísio Passos Ribeiro
Published: October 2016

A radioterapia constitui a modalidade clínica mais utilizada para tratar mestástases cerebrais, tipo mais comum de tumores secundários de mama, pulmão e melanomas. Os protocolos frequentemente utilizam doses diárias elevadas e, dependendo da técnica de irradiação empregada há elevada probabilidade de complicações em tecidos saudáveis. Com o propósito de minimizar os efeitos adversos, é importante a interpretação dosimétrica do planejamento radioterápico tridimensional por meio de imagens tomográficas ou, no caso de simulações 2D, pelo emprego de técnicas que otimizam a distribuição de dose aumentando a homogeneidade. O estudo objetivou comparar os planejamento 2D e conformacional 3D para a irradiação total de cérebro e verificar a evolução desses planejamentos através das técnica “field-in-field”. A metodologia consistiu em simular o planejamento bidimensional, reproduzi-lo em um conjunto de imagens tomográficas e compará-lo com o plano conformacional, tanto para técnica de dois campos quanto para a de quatro campos “field-in-field”. Os resultados mostraram que não há diferenças significativas entre planejamentos 2D e 3D para irradiação de cérebro total, e que a “técnica field in field” melhora sensivelmente a distribuição de dose no volume cerebral comparada à técnica de dois campos. Concluiu-se que a custo efetividade do tratamento é ótima para os 4 campos descritos e que a tomografia de planejamento não é essencial para o caso clinico abordado.
Remoção de fósforo e nitrogênio em efluente de indústria de laticínios por eletrocoagulação
Authors: Taufer Guilherme , Müller Cristine Sippel , Hilgemann Maurício
Published: October 2016

O tratamento de efluentes é uma problemática que vem sendo estudada nos últimos anos devido ao grande potencial degenerativo ao ambiente. Na indústria de laticínios, o efluente possui grande poder poluidor devido à grande disponibilidade de nutrientes, tais como nitrogênio e fósforo, que causam a eutrofização. A eletrocoagulação (EC), que é uma técnica de simples aplicação, baixo custo e gera menos passivos que o tratamento convencional, consiste em aplicar uma determinada corrente entre os eletrodos para a formação de coloides e remoção de poluentes. Assim, o objetivo deste estudo foi avaliar o uso da técnica de EC para a remoção de fósforo e nitrogênio do efluente líquido de uma indústria de laticínios. Um reator de eletrocoagulação em escala de bancada, com capacidade para 400 mL, foi utilizado em conjunto com duas placas de eletrodos de alumínio (Al), colocados paralelamente a uma distância de 3 cm. Durante o experimento de eletrocoagulação, aplicou-se uma corrente de 1 A durante 20 minutos, utilizando-se como resposta os parâmetros turbidez, condutividade, pH, nitrogênio total e fósforo total. Nestas condições obteve-se uma redução de 95,6 % para fósforo total, 71,8 % para nitrogênio total e 94,6 % para a turbidez, e com concentrações compatíveis para o descarte do efluente conforme legislação CONSEMA 128/2006, evidenciando claramente que o método é muito promissor para a aplicação industrial na remoção destes nutrientes.

Published: October 2016

No ambiente marinho uma equação inversa entre a alcalinidade total e a salinidade, denominada de alcalinidade total normalizada (ATN) para mostrar uma relação linear entre esses parâmetros. O objetivo deste trabalho foi avaliar a distribuição superficial e vertical da ATN ao longo da Zona Econômica Exclusiva-ZEE da região Norte do Brasil, com os dados obtidos nas Operações Norte III e Norte IV, dentro do âmbito do Programa de Avaliação do Potencial Sustentável de Recursos Vivos na Zona Econômica Exclusiva (REVIZEE). Os dados demonstraram que o sistema do dióxido de carbono ao longo da ZEE Norte mantém o pH dentro da faixa esperada para o ambiente marinho. Os menores valores de pH (7,48 Norte III e 7,38 Norte IV), de AT (1971µmol kg-1, Norte III e 1878 µmol kg-1 Norte IV) e de ATN (2295 µmol kg-1 Norte III, 2293 µmol kg-1 Norte IV) na camada superficial, foram observados na área com influência da descarga do rio Amazonas, ou seja, com baixos valores de salinidade (28,31 Norte III e 24,00 Norte IV). As massas de águas na coluna de água, encontradas na região, tiveram diferenças na concentração de ATN. Essas diferenças podem ser associadas aos processos de degradação da matéria orgânica, e a formação ou dissolução do carbonato de cálcio. Pesquisas futuras englobando outras formas do sistema do dióxido de carbono, e também com a utilização de métodos mais precisos, irão servir para explicar a dinâmica desse sistema de forma mais precisa.

Creating task-based oral foreign language exams linked to the CEFR in higher education
Authors: Reisenleutner Sandra
Published: October 2016

Oral language exams at university often consist of an individual or group conversation with the examiner about topics dealt with during the semester. A question-and-answer format is applied and vocabulary and structures tested. As a consequence, the oral exam does not reflect action-oriented approaches that often form part of classroom activities and are also fostered by the CEFR. This article describes the process and outcomes to date of action research carried out at the University of Sheffield and the University of Nottingham since 2014. The starting point is that many courses are linked to CEFR levels, which I wanted to include in oral language exams by working with descriptors. The article illustrates ways of making oral language exams more task-based, while still ensuring that topics, structures and vocabulary dealt with during the semester are incorporated. The process of changing the exam is described and examples are given. I also pose the question of how level descriptors of the CEFR might be linked to marking schemes and grading systems of British universities.
Plurilingual proficiency as a learning objective for a multilingual curriculum in the study of business in Finland
Authors: Schlabach Joachim
Published: October 2016

Plurilingual skills are among the key skills required in international business communication. Employees working in international business operations use multiple languages concurrently, switch between them, and mediate between different languages and cultures. Up until now however, the language teaching accompanying business studies at universities has aimed at developing proficiencies geared to single languages. Plurilingual skills such as language alternation, code-switching, mediation, and transfer strategies have not been taken into account. Learning objectives that satisfy the particular requirements of multilingual individuals are thus missing from the curriculum. The Pluriling study, a didactically aligned analysis of the language requirements of the alumni of the Turku School of Economics, presents empirically reliable data that, in the first instance, describes the use of multiple languages in international business communications. Based on answers to open questions, typical plurilingual skills and strategies are defined and summarised under the term
On the Calabi-Yau equation in the
Kodaira-Thurston manifold
Authors: Vezzoni Luigi
Published: October 2016

We review some previous results about the Calabi-Yau equation on the Kodaira-Thurston manifold
equipped with an invariant almost-Kähler structure and assuming the volume form T2-invariant. In particular,
we observe that under some restrictions the problem is reduced to aMonge-Ampère equation by using the
ansatz ˜~ω = Ω− dJdu + da, where u is a T2-invariant function and a is a 1-form depending on u. Furthermore,
we extend our analysis to non-invariant almost-complex structures by considering some basic cases and we
finally take into account a generalization to higher dimensions.
Joint weak hazard rate order under
non-symmetric copulas
Authors: Pellerey Franco , Spizzichino Fabio
Published: October 2016

A weak version of the joint hazard rate order, useful to stochastically compare not independent
random variables, has been recently defined and studied in [4]. In the present paper, further results on this
order are proved and discussed. In particular, some statements dealing with the relationships between the
jointweak hazard rate order and other stochastic orders are generalized to the case of non symmetric copulas,
and its relations with some multivariate aging notions (studied in [2]) are presented. For this purpose, the new
notions of Generalized Supermigrative and Generalized Submigrative copulas are defined. Other new results,
examples and discussions are provided as well.
Telling True Lies. Metanarration, Intertextuality and (Un)reliability in Holberg’s Iter subterraneum
Authors: Velle Thomas
Published: October 2016

Scholarship on Ludvig Holberg’s imaginary voyage Iter subterraneum has noted that the credibility and reliability of both the narrator Klim, and his narration are problematized throughout the text. In doing so, scholars have simplified the text’s narratological structure. This article defamiliarizes the (un)reliability of Klim’s narration by distinguishing three levels in the text: Klim’s intentional discourse, which aims at authenticating the narration, a second level on which the authenticating function of Klim’s discourse is undermined by intertextual links with classical and modern authors, and thirdly, the role of Abeline as the translator of Klim’s text into Latin, which complicates Klim’s reliability even more. These levels and their interactions are explored by a close reading of metanarrative comments in Klim’s discourse, in order to understand the narratological dynamics in Holberg’s text more profoundly and, thereby, to deepen the scholarly view on Klim’s (un)reliability.
Ingvar Ambjørnsens hytte-noir
Authors: Rees Ellen
Published: October 2016

This article considers links between contemporary Norwegian writer Ingvar Ambjørnsen’s novel Natten drømmer om dagen (2012; The night dreams of the day) and the concept of noir, both in relation to more traditional film noir, to classic hard-boiled crime fiction, and to the recent trend in crime fiction and television known popularly as “Nordic noir”. The author argues that Ambjørnsen reworks key elements of noir aesthetics and thematics, for example relocating the setting from the more typical “urban jungle” to an equally dark and brooding forest landscape. Ambjørnsen simultaneously activates and dismantles tropes associated with both Norwegian identity (nature, the vacation cabin) and with noir (the anti-hero, the femme fatale) to create a complex social critique of late modern Norwegian society.
Trollism, Reality Hunger, and Vulnerability. Trolls in film and literature in the 2000’s
Authors: Dancus Adriana Margareta
Published: October 2016

Trolls have become increasingly salient in contemporary Nordic film and literature. This article sets up to understand the dissemination of cinematic and literary trolls of the 2000’s by providing a comparative analysis of three contemporary texts: the Norwegian mockumentary Trollhunter (André Øvredal, 2010) and two fantasy novels, Troll: A Love Story by Finnish writer Johanna Sinisalo (2000) and Stallo by Swedish author Stefan Spjut (2012). In addition to comparing contemporary trolls to more established troll conceptualizations from Nordic folklore and children’s literature, I will also analyze trolls in a larger cultural and socio-political context by tying them to aesthetic movements such as the reality hunger in contemporary Scandinavian art and the vulnerability of the contemporary socio-political moment.

Published: October 2016

Large-scale integration of wind turbine generators (WTGs) may have significant impacts on power system operation with respect to system frequency and bus voltages. This paper studies the effect of Static Var Compensator (SVC) connected to wind energy conversion system (WECS) on voltage profile and the power generated from the induction generator (IG) in wind farm. Also paper presents, a dynamic reactive power compensation using Static Var Compensator (SVC) at the a point of interconnection of wind farm while static compensation (Fixed Capacitor Bank) is unable to prevent voltage collapse. Moreover, this paper shows that using advanced optimization techniques based on artificial intelligence (AI) such as Harmony Search Algorithm (HS) and Self-Adaptive Global Harmony Search Algorithm (SGHS) instead of a Conventional Control Method to tune the parameters of PI controller for SVC and pitch angle. Also paper illustrates that the performance of the system with controllers based on AI is improved under different operating conditions. MATLAB/Simulink based simulation is utilized to demonstrate the application of SVC in wind farm integration. It is also carried out to investigate the enhancement in performance of the WECS achieved with a PI Controller tuned by Harmony Search Algorithm as compared to a Conventional Control Method.

The Duality of Page and Stage: Constructing Lyrical Voices in Contemporary British Poetry Written for Performance
Authors: Tönnies Merle , Brüning Joana , Sand Andrea
Published: October 2016

The paper uses an interdisciplinary approach to analyse characteristic works by three contemporary British authors who come from different backgrounds but have all, in various ways, brought a performative perspective to bear on their poetry: Patience Agbabi, Jackie Kay, and Ben Mellor. The focus is on the concrete techniques which the poets use to construct different lyrical voices in the written texts as well as in performance. With their emphasis on difference(s), they seem to align themselves closely with broader literary and cultural developments like postmodernism or Stuart Hall’s ‘politics of representation,’ while nevertheless repeatedly suggesting the possibility of a unifying centre behind the text. All in all, the detailed analyses of the poems show the authors to take up different positions in the continuum between orality and writing, unity and diversity, as well as political intervention and playfulness.
Activation of a Habenulo–Raphe Circuit Is Critical for the Behavioral and Neurochemical Consequences of Uncontrollable Stress in the Male Rat
Authors: Dolzani Samuel D. , Baratta Michael V. , Amat Jose , Agster Kara L. , Saddoris Michael P. , Watkins Linda R. , Maier Steven F.
Published: October 2016

Exposure to uncontrollable stress [inescapable tailshock (IS)] produces behavioral changes that do not occur if the stressor is controllable [escapable tailshock (ES)] an outcome that is mediated by greater IS-induced dorsal raphe nucleus (DRN) serotonin [5-hydroxytryptamine (5-HT)] activation. It has been proposed that this differential activation occurs because the presence of control leads to top–down inhibition of the DRN from medial prefrontal cortex (mPFC), not because uncontrollability produces greater excitatory input. Although mPFC inhibitory regulation over DRN 5-HT activation has received considerable attention, the relevant excitatory inputs that drive DRN 5-HT during stress have not. The lateral habenula (LHb) provides a major excitatory input to the DRN, but very little is known about the role of the LHb in regulating DRN-dependent behaviors. Here, optogenetic silencing of the LHb during IS blocked the typical anxiety-like behaviors produced by IS in male rats. Moreover, LHb silencing blocked the increase in extracellular basolateral amygdala 5-HT during IS and, surprisingly, during behavioral testing the following day. We also provide evidence that LHb–DRN pathway activation is not sensitive to the dimension of behavioral control. Overall, these experiments highlight a critical role for LHb in driving DRN activation and 5-HT release into downstream circuits that mediate anxiety-like behavioral outcomes of IS and further support the idea that behavioral control does not modulate excitatory inputs to the DRN.
Cracking Up Time
Authors: Wood Katelyn Hale
Published: October 2016

This essay theorizes how black feminist comedic performance queers white supremacist and heteronormative notions of time by centering Wanda Sykes's performance in her comedy special I'ma Be Me and her performance at the White House Correspondents' Dinner—both in 2009. Sykes's jokes articulate how queer bodies of color experience temporalities that are in constant tension with dominant narrations of “coming out,” national heritage, and white nostalgia. I argue that Sykes uses comedic performance to: (1) reveal the limits of “progressive” coming out narratives for black queer women, (2) reinstate black subjectivity into US collective memory, (3) debunk myths of the United States as “post-” identity politics, and (4) challenge broader publics to think beyond linear and binary constructions of identity/ies, space, and time.
A Journey from Willful Ignorance to Liberal Guilt to Black Feminist Thought
Authors: Waters Kristin
Published: October 2016

How can white feminists productively engage with black feminist thought and practice? What are some of the excuses and stumbling blocks white feminists use and encounter that circumvent alliance with black feminists and others at the intersections of different raced and gendered realities? This essay suggests the need to further a comprehensive epistemological framework, one that distinguishes between a willful ignorance that reinforces hegemonic whiteness and the reflexivity required to move towards dismantling willful ignorance, improving knowledge projects, and creating liberatory frameworks and alliances.
Black Feminist Thought as Oppositional Knowledge
Authors: Collins Patricia Hill
Published: October 2016

How might Black feminist thought remain oppositional, reflexive, resistant, and visionary in the context of contemporary intellectual and political challenges? This essay examines this challenge by engaging two questions. First, is Black feminist thought still oppositional and, if so, in what ways is it oppositional in this era? Second, what will it take for Black feminist thought to remain oppositional under current social and political conditions that appear inclusionary?
Having Her Cheesecake and Eating It
Authors: Wright Ellen
Published: October 2016

Bunny Yeager was a pinup model and photographer who appeared on TV and in exploitation films, while creating pinups and “art” nudes for Playboy, coffee-table books, and how-to publications. She is currently experiencing a revival as part of a subcultural vogue for 1950s and 1960s Americana. In her images she was often both subject and photographer, and her self-reflexive pictures engage with issues of authorship, control, and the sexualized gaze. This text examines Yeager's portraiture, her instructive writing, her representation in the film Bunny Yeager's Nude Camera (1963), and the way she positioned herself when discussing her work, to demonstrate how she embodied a mode of professional and sexual agency that engaged with broader, progressive ideas pertaining to women's labor and identity circulating in 1960s America as part of feminism's second wave.
