Borderline Personality Disorder in the perinatal period: early infant and maternal outcomes
Authors: Blankley Gaynor , Galbally Megan , Snellen Martien , Power Josephine , Lewis Andrew J
Published: July 2015

Objective:

This study examines pregnancy and early infant outcomes of pregnant women with a clinical diagnosis of Borderline Personality Disorder presenting for obstetric services to a major metropolitan maternity hospital in Victoria, Australia.

Method:

A retrospective case review of pregnancy and early infant outcomes on 42 women who had been diagnosed with Borderline Personality Disorder via psychiatric assessment using DSM-IV-R criteria was undertaken. Outcomes were compared with a control group of 14,313 consisting of women and infants of non-affected women from the same hospital over the same period of time.

Results:

Women presenting for obstetric services with a clinical diagnosis of Borderline Personality Disorder experienced considerable psychosocial impairment. They anticipated birth as traumatic and frequently requested early delivery. High comorbidity with substance abuse was found and high rates of referral to child protective services. Mothers with Borderline Personality Disorder were significantly more likely to have negative birth outcomes such as lowered Apgar scores, prematurity and special care nursery referral when compared with controls.

Conclusions:

These findings offer preliminary evidence to be considered by clinicians in developing treatments and services for the perinatal care of women with Borderline Personality Disorder and their infants. Further research is required in order to develop evidence informed clinical guidelines for the management of women with Borderline Personality Disorder and their infants.
Metal-wire-based twin one-dimensional orthogonal array configuration of PZT patches for damage assessment of two-dimensional structures
Authors: Naskar Susmita , Bhalla Suresh
Published: July 2015

This article presents a new field-deployable algorithm harnessing the metal-wire-based variant of the electro-mechanical impedance technique, warranting drastically lesser number of piezo sensors, for damage detection and localization on large two-dimensional structures such as plates. The metal-wire-based approach is a new variant of the electro-mechanical impedance technique. Although less sensitive than the conventional electro-mechanical impedance technique, it is a panacea in situations where direct bonding of lead zirconate titanate (PZT) patches on the host structure is not possible, such as inaccessible structural locations, parts under continuous impact from external loads, brittle materials (triggering signatures without any peaks) or high-temperature locations. This article first reports detailed experimental investigations into the practical aspects of the metal-wire-based electro-mechanical impedance technique. These cover the effect of various associated parameters, such as the wire cross-section, shape, discontinuity and other related issues. Repeatability of signature is also investigated along with the effect of possible breakage in the wire and inadvertent bending. The technique is further adapted by replacing the wire by a thin foil, which is found to improve the damage sensitivity substantially. The proposed algorithm for damage localization on two-dimensional structures uses the PZT patches in the metal-wire-based orthogonal twin-array configuration. The metal-wire-based electro-mechanical impedance technique is first simulated through finite element method, coupled with the basic impedance model, to test the algorithm on the numerical model of a mild steel plate, 1200 mm×970 mm×8 mm in size. The algorithm is then validated through full-scale test on the actual plate, covering damage at various locations. The developments of this article shall pave way for practical application of the metal-wire-based electro-mechanical impedance technique on large two-dimensional structures with minimum number of sensors, especially in situations where the direct electro-mechanical impedance technique is not feasible to be used.
Arezzo-flexible manufacturing system: A generic flexible manufacturing system shop floor emulator approach for high-level control virtual commissioning
Authors: Berger Thierry , Deneux Dominique , Bonte Thérèse , Cocquebert Etienne , Trentesaux Damien
Published: July 2015

The benchmark of several high-level control strategies is required during the design of flexible manufacturing systems. Virtual commissioning is a popular approach to test and validate the behavior of the target control system based on a virtual model. It can actually simulate and help study the behavior of electro-mechanical shop floor components, characterized by a physical layer and low-level control functions but it fails to simulate the behavior of high-level control functions, such as dynamic resource allocation and product routing. Thus, virtual commissioning of the flexible manufacturing system can be a complex task because it requires to model the low- and high-level control functions in different software environments and to connect them through a specific interface. Switching from “virtual” to “real” remains a challenging issue since it requires to connect the high-level control functions to the real system through the real interface. This article introduces and details the Arezzo-flexible manufacturing system approach for supporting the virtual commissioning of the flexible manufacturing system, including the distinct but consistent modeling of their low- and high-level control functions. The Arezzo-flexible manufacturing system approach consists in gradually defining an emulator of the shop floor to which several candidate high-level control strategies can connect through a standard interface layer. The interface layer to the virtual shop floor emulates the real interface layer to the real shop floor, so that switching from the virtual to the real environment is straightforward. In this article, both the emulator design method and the involved generic components needed are described in turn. A real flexible cell is used as a case study to demonstrate the Arezzo-flexible manufacturing system approach and some illustrations are provided to emphasize the similarity between the shop floor emulator obtained (Arezzo-APV) and the real shop floor (Aip-Primeca flexible manufacturing system cell).
Intelligent fuzzy logic with firefly algorithm and particle swarm optimization for semi-active suspension system using magneto-rheological damper
Authors: Ab Talib Mat Hussin , Mat Darus Intan Zaurah
Published: July 2015

This paper presents a new approach for intelligent fuzzy logic (IFL) controller tuning via firefly algorithm (FA) and particle swarm optimization (PSO) for a semi-active (SA) suspension system using a magneto-rheological (MR) damper. The SA suspension system’s mathematical model is established based on quarter vehicles. The MR damper is used to change a conventional damper system to an intelligent damper. It contains a magnetic polarizable particle suspended in a liquid form. The Bouc–Wen model of a MR damper is used to determine the required damping force based on force–displacement and force–velocity characteristics. The performance of the IFL controller optimized by FA and PSO is investigated for control of a MR damper system. The gain scaling of the IFL controller is optimized using FA and PSO techniques in order to achieve the lowest mean square error (MSE) of the system response. The performance of the proposed controllers is then compared with an uncontrolled system in terms of body displacement, body acceleration, suspension deflection, and tire deflection. Two bump disturbance signals and sinusoidal signals are implemented into the system. The simulation results demonstrate that the PSO-tuned IFL exhibits an improvement in ride comfort and has the smallest MSE for acceleration analysis. In addition, the FA-tuned IFL has been proven better than IFL–PSO and uncontrolled systems for both road profile conditions in terms of displacement analysis.
Vibration and acoustic radiation of an orthotropic composite cylindrical shell in a hygroscopic environment
Authors: Zhao Xin , Zhang Bo , Li Yueming
Published: July 2015

An analytical study is presented for vibration and acoustic radiation of a finite thin orthotropic composite cylindrical shell excited by a harmonic concentrated force in a hygroscopic environment. The modal analysis method is used to solve the governing equations. Theoretical results are presented in natural vibration, radial quadratic velocity, sound power and radiation efficiency, with uniform incremental moisture content. Furthermore, different stiffness, length and thickness are set respectively to research the effects of the material and structure parameters variation of the orthotropic cylindrical shell on the vibration and acoustic radiation characteristics. It is found that the natural frequencies decrease with an increase of moisture content. The modal indices associated with the lowest frequency mode reaches the modal indices corresponding to the lowest buckling mode near the critical buckling moisture content with moisture content. The radial quadratic velocity and sound radiation power decrease with the incremental moisture content in the lower frequency band. The vibration and acoustic response decrease with the enhanced stiffness. The increasing length has little impact on the sound radiation and the thickened cylindrical shell weakens the sound radiation response.
Model-based fatigue crack identification in rotors integrated with active magnetic bearings
Authors: Singh Sandeep , Tiwari Rajiv
Published: July 2015

This paper investigates the behavior of a rotor-bearing system with a breathing crack, under the action of active magnetic bearings, implemented to suppress the vibration induced by the presence of the crack and the unbalance. In such a case, identification of the crack with help of vibration signals may be difficult; other observables such as the controller current may be utilized for the purpose. Linear system equations of motion together with the switching crack excitation function are used to develop the identification algorithm. The use of full spectrum analysis is made to determine the crack force coefficients of the harmonics exciting the rotor in the same and the reverse direction of the rotor spin. Usage of these coefficients in the identification algorithm estimates the viscous damping, disc unbalance and additive crack stiffness. The algorithm has been tested for measurement noise and bias errors in system parameters, for robustness. In practical terms, the situation analyzed in this paper relates to identification of crack and other parameters in a rotor integrated with an active magnetic bearing.
Prosecuting Intimate Partner Sexual Assault
Authors: O’Neal Eryn Nicole , Tellis Katharine , Spohn Cassia
Published: July 2015

Prosecutors play a crucial role in determining whether persons who are accused of intimate partner sexual assault (IPSA) will be sanctioned by the criminal justice system. Prosecutors have unconditional discretion at the initial charging stage because a case rejection decision is typically immune to review. Using qualitative data from 47 IPSA complaints that were referred to Los Angeles County or City prosecution in 2008, this study examines the factors that influence charging decisions. Findings suggest that prosecutors consider both legal and extralegal factors when making charging decisions and that various cultural, legal, and rape myths surrounding IPSA influence these decisions.
Insertion and Management of Temporary Pacemakers
Authors: Sullivan Breandan Lawrence , Bartels Karsten , Hamilton Natalie
Published: July 2015

Temporary pacemakers are used in a variety of critical care settings. These life-saving devices are reviewed in 2 major categories in this review: first, the insertion and management of epicardial pacemakers after and during cardiac surgery; and second, the insertion of transvenous temporary pacemakers for the emergent treatment of bradyarrhythmias. Temporary epicardial pacemakers are used routinely in patients recovering from cardiac surgery. Borrowing from advances in cardiac resynchronization therapy there are many theoretical and untested benefits to pacing the postoperative cardiac surgery patient. Temporary transvenous pacing is traditionally an emergency procedure to stabilize patients suffering from hemodynamically unstable bradyarrhythmia. We review the traditional and expanding use of transvenous pacemakers inside and outside the operating room.
Using Ethnography of Communication in Organizational Research
Authors: Kalou Zoi , Sadler-Smith Eugene
Published: July 2015

Ethnography of Communication offers new analytical and interpretive possibilities for contextually sensitized, language- and communication-based ethnographic studies of management and organization. In this article we provide an introduction and overview of relevant linguistic and related fields, positioning Ethnography of Communication within the broader context of anthropology, ethnomethodology, and sociolinguistics. We describe Dell Hymes’s seminal contribution to theory and method of Ethnography of Communication (foregrounding Hymes’s signature concept of “communicative competence”) and outline what the application of an Ethnography of Communication approach in management research might entail (illustrating the application of Hymes’s SPEAKING grid). We conclude by offering an example of how the methods of Ethnography of Communication might be applied usefully to the study of organizational language, discourse, and communication.
The function and field of speech and language in neoliberal education
Authors: Parker Ian
Published: July 2015

This article explores the role of psychoanalysis in contemporary neoliberal management of higher education, as a critical resource and as an aspect of the problem it describes. The marketisation, privatisation and financialisation of the university sector is the context for a brief case example in which we see the logic of fantasy staged in a particular organisation, and this case example is followed by a review of the distinctive forms of management of subjectivity in higher education which sustain the context for such events. I bring aspects of Lacanian psychoanalysis to bear on the development of current neoliberal management strategies in universities and then methodological principles are extracted from Lacan’s 1953 foundational text ‘The Function and Field of Speech and Language in Psychoanalysis’; the principles concern the application of psychoanalysis, the place of speech as site of truth, language conceptualised here as psychoanalytic discourse, the gap between speech and language manifested in alienation and symptoms, resistance expressed in jokes and the formation of specific domains in which psychoanalytic reasoning is operative today. I argue that neoliberal management realises the worst aspects of the problems Lacan identifies in his text; knowledge as grounding for education and interpretation, treatment underpinned by charitable concern and the performance of expertise tied to power. I focus on Lacan’s warnings about the popularisation of psychoanalytic discourse and conclude with comments on the way ‘analysis’ now takes place outside the clinic.
Organizational resistance as a vector of deterritorialization: The case of WikiLeaks and secrecy havens
Authors: Munro Iain
Published: July 2015

This article investigates the relations of power and resistance manifest by the WikiLeaks network. The primary research question of this inquiry is, ‘what power relations and possibilities for resistance are presented by WikiLeaks as a novel form of network organization?’ The article shows that WikiLeaks has been able to exert influence from the periphery of existing networks by exploiting vectors of ‘deterritorialization’ to destabilize existing power relations. The article contributes to the literature on the network organization by developing an account of resistance to State and corporate power in terms of an ‘absolute deterritorialization’. This idea has important implications for the tactics of resistance in network organizations, where vectors of deterritorialization have become a defining feature of resistance tactics of the WikiLeaks network.
Co-creation of what? Modes of audience community collaboration in media work
Authors: Malmelin Nando , Villi Mikko
Published: July 2015

This article explores processes of co-creation in the media industry, particularly in the context of magazine media brands. We discuss the content and practices of creative collaboration between editorial teams and online audience communities. Based on two empirical case studies using analytical interviews and focus group discussions, we introduce a new model and framework for analysing co-creative processes. The model of co-creative collaboration is focused on three areas of media work: production, marketing and development. We conclude that co-creative processes between editorial teams and audience communities have a definite impact on the future of media work and media management. Importantly, the work of editorial teams is transformed from content production through creating platform concepts to coordinating, managing and nurturing audience communities.
“A world crazier than us”: Vanishing social contexts and the consequences for psychiatric practice in contemporary Romania
Authors: Friedman Jack R.
Published: July 2015

Since the end of Communism, mental health care in Romania has increasingly sought to align its practices with idealized models of Western psychiatric practice. Much of this realignment has been made possible by accessing and integrating new pharmaceuticals into psychiatric hospital settings. Less straightforward have been the painful attempts to create a system modeled on international standards for training and certifying psychotherapists. Unfortunately, the political, economic, infrastructural, and epistemological environment of the Romanian mental health care system has prevented many other reforms. This paper examines the ironic trajectory that Romanian psychiatry has taken since the end of state socialism. Specifically, this paper shows how psychiatric practice in most places (outside of university-training hospitals) is increasingly disconnected from a concern with the social conditions that surround mental illness during a period when social upheaval is profoundly impacting the lives of many people who receive mental health care. Thus, as the contribution of social problems to the suffering of those with mental illnesses has increased, some Romanian mental health practitioners have moved away from a concern with these social problems under the guise of aligning their psychiatric practices with (imagined) Western standards of biomedical care. The paper provides a brief history of Romanian psychiatry and explores contemporary challenges and contradictions in many Romanian psychiatric treatment settings through the case study of a 31-year-old Romanian female diagnosed with paranoid schizophrenia.
Paradoxes of new media: Digital discourses on Eurovision 2014, media flows and post-Soviet nation-building
Authors: Miazhevich Galina
Published: July 2015

This article explores the contradictions inherent in new media representations of sexual minorities in two bordering post-Soviet countries, Belarus and Lithuania. These nations are divided by their non/membership of the European Union and, being at the western periphery of the former Russian imperial centre, remain directly affected by the Russian mediascape and its information flows. While both countries’ state media closely adhere to the Russian establishment’s homophobic discourse, the role of new media remains largely uncharted. This article uses discourse analysis to (a) examine the influence of Russian media on each nation’s digital discussions about sexual minorities and (b) explore new media’s potential to mediate the intersection of sexual minorities and nation-building in two post-Soviet states. The analysis is centred on a set of online media publications (including their ‘comments’ sections), generated by the Eurovision Song Contest 2014 being won by Conchita Wurst, a drag performer with a beard.
“I miss my mobile phone!”: Self-expansion via mobile phone and responses to phone loss
Authors: Hoffner Cynthia A , Lee Sangmi , Park Se Jung
Published: July 2015

This article explores how mobile phones function as an affective technology for young adults, by adapting the self-expansion model to understand attachment to mobile phones. In an online survey, 272 smart phone users reported on their recalled responses to loss/separation from their mobile phone (not by choice), as well as their use of the mobile phone for self-expansion. Results show that self-expansion via mobile phone was associated with greater inclusion of the mobile phone in the self-concept and greater subjective well-being. Most respondents reported negative feelings, such as loneliness/disconnection, anxiety, and boredom, when without their mobile phone, but others felt relieved to be out of touch with others. The use of the mobile phone for self-expansion was associated with more negative emotion and less positive emotion (relief) in response to loss/separation from the phone. Interpretations of the findings are discussed.
Determination of forming limit curve in two-layer metallic sheets using the finite element simulation
Authors: Karajibani Ehsan , Hashemi Ramin , Sedighi Mohammad
Published: July 2015

Forming limit curve (FLC) is a suitable method for determining the metallic sheets formability. The purpose of the present research is to expose a simulation-based approach to predict the FLC in two-layer metallic sheets. In this paper, the formability of two-layer (AA3004-ST12) metallic sheets, with an aluminum inner layer (in contact with the punch) and a steel outer layer (in contact with the die) was numerically investigated. Two distinct criteria, including the acceleration (i.e. the second time derivatives) of thickness, and major strain extracted from the strain history information of finite element software, were applied to determine the commencement of local necking in FLCs. It shows that the localized necking starts when the acceleration of the thickness or major strain, is maximized. The published experimental results for AA3004/ST12 two-layer metallic sheets were employed in order to evaluate the simulation results. It is shown that the presented methods are noticeably aligned with the published experimental data. By the grace of present methods, the effects of some process parameters on the FLC have been investigated. It is shown that process parameters such as thickness and lay-up of each layer will have significant influences on FLC of two-layer metallic sheets.
Taking normative sense seriously: Ethnography in the light of a utopian referent
Authors: Trondman Mats
Published: July 2015

The paper starts by stating a possible meaning of ethnography within cultural sociology. Then follows an investigation of the ‘normative sense’ in human life that ethnographers not only tend to investigate but also inhabit themselves. The main purpose is to argue that this normative sense needs not necessarily to be shunned, but can be justified as an urgent, conscious, and explicit constituent that enacts theoretically inspired and meaningfully illuminating ethnographic endeavors. This is done by a positive construction and an immanent critique of cultural sociologist Isaac Reed’s work on interpretation and social knowledge, i.e. different forms of epistemic modes, which in this paper is labeled the theoretical, the empirical and the utopian referent, or the pragmatics of grounded re-signification. The paper ends by trying to state the interlaced relationship, or subscription, between these theoretical, empirical and utopian re-significations and the possibility of a thrice-blessed social criticism. Thus, this is what it could mean to take the normative sense seriously.
Inverse methods for quantitative assessment of delamination damage based on vibrational response
Authors: He Shuai , Rose LR Francis , Wang Chun H
Published: July 2015

A novel two-step approach for quantifying laminar damages, such as delaminations in composites, is presented. This new approach first employs the gapped smoothing method to locate the edges of damage from the vibrational curvature data, followed by an inverse method to determine the through-thickness location of delaminations that provide the best match with the local reduction in bending stiffness over the damaged region. Practical aspects of the implementation of this procedure are discussed, and the approach is demonstrated using both simulated and experimental data. The role of sample spacing on the accuracy of damage location is investigated systematically and it is shown that an optimum spacing exists for experimental data containing noise. The inverse method is found to be able to provide detailed information of delaminations when the searching space is limited, and it can also be used to determine the effective flexural stiffness for complex delamination damage.
Insider action research and the microsystem of a Danish surgical ward
Authors: Paltved Charlotte , Morcke Anne Mette , Musaeus Peter
Published: July 2015

This insider action research project aimed to improve interprofessional team performance at a surgical ward. The purpose of the project was (1) to critically appraise potential deficiencies in staffs’ identification, clinical judgment, and management of deteriorating ward patients, (2) to develop an interprofessional change model, and (3) evaluate the impact of the change model and the AR process. The insider AR project took place at a large Danish surgical ward with 60 participating physicians and nurses. The study was conducted in three interconnected action and reflection cycles using mixed methods. Staff viewed the co-creation and co-inquiry as important resources in transforming the ward into a better microsystem. Microsystems as a theoretical framework was used to conceive the success of health system redesign as a matter of enabling the clinical team to meet patient needs. By combining insider AR with microsystems, this study highlights the importance of senior leaders to recognize the nature and power of using the microsystem approach for strategy, excellence, innovation, and research. Staff was able to formulate an overarching vision of interprofessionalism and this helped inspire changes in clinical practice for the benefit of our patients.
Design of an anidolic concentrator and evaluation of daylight enhancement under an overcast sky
Authors: Nair MG , Ramamurthy K , Ganesan AR
Published: July 2015

This paper discusses the performance evaluation of anidolic concentrators in an overcast sky condition. The concentrators were designed, with acceptance angles of 60°, 70° and 80°, first by maintaining the profile of the concentrator’s uniform and secondly by keeping the height uniform. Studies were done using these concentrators with a model light pipe and the performance was compared with that of an acrylic dome and a profiled Fresnel collector. For a given condition, the illuminance ratio (ratio of illuminance measured at the base of the pipe to external illumination) increased with the acceptance angle. For a given acceptance angle, the concentrator with uniform height and variation of entrance aperture, performed better than a concentrator having a uniform profile.
On the calculation and measurement of mean room surface exitance
Authors: Duff J , Antonutto G , Torres S
Published: July 2015

Cuttle has proposed mean room surface exitance as a metric for use within interior lighting design. Two reported barriers to its use are: a lack of available software to calculate the metric and the tedious and cumbersome nature of recording its values in the field using current equipment and methodologies. This paper presents a method for facilitating the calculation of mean room surface exitance using readily available freeware, namely Radiance, and also presents a methodology that utilises high dynamic range imaging as a pragmatic alternative for field measurement.
Assessment of Treatment Response With Diffusion-Weighted MRI and Dynamic Contrast-Enhanced MRI in Patients With Early-Stage Breast Cancer Treated With Single-Dose Preoperative Radiotherapy
Authors: Wang Chunhao , Horton Janet K. , Yin Fang-Fang , Chang Zheng
Published: July 2015

Single-dose preoperative stereotactic body radiotherapy is a novel radiotherapy technique for the early-stage breast cancer, and the treatment response pattern of this technique needs to be investigated on a quantitative basis. In this work, dynamic contrast-enhanced magnetic resonance imaging and diffusion-weighted magnetic resonance imaging were used to study the treatment response pattern in a unique cohort of patients with early-stage breast cancer treated with preoperative radiation. Fifteen female qualified patients received single-dose preoperative radiotherapy with 1 of the 3 prescription doses: 15 Gy, 18 Gy, and 21 Gy. Magnetic resonance imaging scans including both diffusion-weighted magnetic resonance imaging and dynamic contrast-enhanced magnetic resonance imaging were acquired before radiotherapy for planning and after radiotherapy but before surgical resection. In diffusion-weighted magnetic resonance imaging, the regional averaged apparent diffusion coefficient was calculated. In dynamic contrast-enhanced magnetic resonance imaging, quantitative parameters Ktrans and ve were evaluated using the standard Tofts model based on the average contrast agent concentration within the region of interest, and the semiquantitative initial area under the concentration curve (iAUC6min) was also recorded. These parameters’ relative changes after radiotherapy were calculated for gross tumor volume, clinical target volume, and planning target volume. The initial results showed that after radiotherapy, initial area under the concentration curve significantly increased in planning target volume ( P < .006) and clinical target volume ( P < .006), and ve significantly increased in planning target volume ( P < .05) and clinical target volume ( P < .05). Statistical studies suggested that linear correlations between treatment dose and the observed parameter changes exist in most examined tests, and among these tests, the change in gross tumor volume regional averaged apparent diffusion coefficient ( P < .012) and between treatment dose and planning target volume Ktrans ( P < .029) were found to be statistically significant. Although it is still preliminary, this pilot study may be useful to provide insights for future works.
Measuring User Experience in Multiplayer Board Games
Authors: Barbara Jonathan
Published: July 2015

Comparison of user experience between multiplayer digital games and board games is largely unexplored in the literature, with no instrument found to suitably measure user experience across game formats. This study explores the use of the Social Presence module of the Games Experience Questionnaire to measure user experience in a multiplayer board game involving 12 participants across 3 separate sessions. Scale analysis and correlation with semistructured interviews held with the participants suggest that the instrument is reliable and valid and can thus be used for measurement and comparison of user experience across game formats. The Games Experience Questionnaire can therefore be used to scale-up board game research by diminishing reliance on interviews as well as to assist in the choice between digital and nondigital implementation of gameplay forming part of an overarching story, such as in transmedial productions.
Therapeutic challenges after successful thrombectomy in a patient with an antiphospholipid syndrome associated M1-occlusion: A case report

Published: July 2015

Backround

Stroke is a frequent disorder in patients with an antiphospholipid syndrome (APS). Due to a high risk for further thromboembolic events, appropriate anticoagulation therapy in patients with an APS-associated stroke seems mandatory but drug eluting and duration is a matter of debate.

Case

A 48-year-old female patient presented with Broca’s aphasia and mild hemiparesis on the right side. Diagnostic work-up revealed left middle cerebral artery (MCA) occlusion yet without diffusion-weighted lesions. Due to a thrombocytopenia (67.00 g/l) systemic thrombolysis was not indicated and endovascular treatment was initiated 150 min after symptom onset. After successful clot retrieval, recurrent re-occlusions lead to the necessity of stent implantation and anticoagulation, respectively. On day 5 she developed a new severe right-sided hemiparesis. The magnetic resonance imaging (MRI) showed a subtotal restenosis of the left MCA despite the regular anticoagulation regime leading to a new left MCA ischaemic stroke. In the meantime, the unknown aetiology, the patients’ age and the thrombocytopenia let to further diagnostic workup. Elevated blood parameters such as lupus anticoagulant (LA)-1, LA-ratio, positive anti-nuclear antibody (ANA), p-anti-neutrophil cytoplasmic antibodies (ANCA), c-ANCA confirmed the diagnosis of APS.

Conclusion

This case report showed the feasibility of mechanical clot retrieval and stent implantation in patients with APS. Due to the elevated risk of in-stent thrombosis a prolonged therapy with glycoprotein (GP)IIb/IIIa receptor antagonists in the initial postoperative period and further anticoagulation with coumarin derivate might be needed.
Improved flow performance of a centrifugal compressor based on pit formation on the notum of the whirligig beetle (Gyrinidae Latreille)
Authors: Tian Limei , Li Ziyuan , Jin E , Ke Qingpeng , Dong Shiyun , Ma Yunhai
Published: July 2015

Many studies have shown that bionic forms reduce drag through the control fluid medium. In this study, the evenly aligned pits of the whirligig beetle ( Gyrinidae Latreille) notum were selected as the bionic form to be studied. They were used in centrifugal compressor impellers, called bionic centrifugal compressors, and the flow characteristics were simulated and compared to the prototype compressor. The simulation results show that compared to the prototype compressor, the pressure drag of bionic centrifugal compressors was reduced dramatically, while the pressure ratio was significantly improved. The pressure drag decreased by 19.24%, while the compression ratio increased by 9.8%. The bionic form of the blade delayed the boundary layer separation of the impeller suction surface, reducing the turbulent kinetic energy loss and improving internal air flow. The effect of drag reduction was shown to have a close relationship with the dimple size and bionic surface area; the greater the area, the better the drag reduction effect. However, there should exist an optimal bionic area, which could be determined by considering the flow velocity inside the impeller.
9/11 and the evolution of newspaper representations of incarcerated Muslims
Authors: Umamaheswar Janani
Published: July 2015

Prior research has examined public attitudes towards—and media portrayals of—Muslims in the United States following the terrorist attacks of September 11, 2001. Scholars, however, have yet to examine media portrayals of incarcerated Muslims in the era following the attacks. In this article, I analyze newspaper reports published before and after the 9/11 attacks to examine whether representations of incarcerated Muslims shifted following the attacks. Findings indicate that although terrorism and the war on terror, inmate radicalization, and the significance of Muslim chaplains are themes that emerged only in post-9/11 reports, there is also substantial overlap in the content of reports published before and after the attacks. These findings are interpreted by drawing on the minority threat perspective.
Reimagining ethical leadership as a relational, contextual and political practice
Authors: Liu Helena
Published: July 2015

Interest in ethical leadership has been spurred by the widespread reporting of corporate malfeasance and corruption in the last decade. Although ethical leadership theories have highlighted the importance of ethical considerations in leadership, the dominant discourses of this field tend to treat ethical leadership as individualised, decontextualised and power-neutral. The purpose of this article is to address these limitations of the mainstream literature through a reimagination of ethical leadership research, development and practice grounded in a feminist, communitarian and corporeal ethic. This approach, I propose, has the potential to reorient leadership as a collective ethico-political project exercised towards the goals of equality, justice and emancipation.
Vomiting and diarrhoea in children
Authors: Mathieson Liusaidh
Published: July 2015

Vomiting and diarrhoea caused by acute gastroenteritis is a very common paediatric presentation. Although often self-limiting and self-managed, around 10% of children under the age 5 years will present to healthcare professionals every year. The majority are managed by primary care services. Some studies suggest that oral rehydration sachets are under- prescribed and that too many children are referred to secondary care. This article considers the aetiology, clinical assessment, investigation and management of vomiting and diarrhoea in children.
A Statistical Analysis of a Traffic-Light Food Rating System to Promote Healthy Nutrition and Body Weight
Authors: Larrivee Sandra , Greenway Frank L. , Johnson William D.
Published: July 2015

Background:

Restaurant eating while optimizing nutrition and maintaining a healthy weight is challenging. Even when nutritional information is available, consumers often consider only calories. A quick and easy method to rate both caloric density and nutrition is an unmet need. A food rating system created to address that need is assessed in this study.

Methods:

The food rating system categorizes food items into 3 color-coded categories: most healthy (green), medium healthy (yellow), or least healthy (red) based on calorie density and general nutritional quality from national guidelines. Nutritional information was downloaded from 20 popular fast-food chains. Nutritional assessments and the 3 color coded categories were compared using the Wilcoxon and Median tests to demonstrate the significance of nutrition differences.

Results:

Green foods were significantly lower than yellow foods, which in turn were significantly lower than red foods, for calories and calories from fat, in addition to content of total fat, saturated fat and carbohydrates per 100 g serving weight (all P < .02). The green foods had significantly lower cholesterol than the yellow ( P = .0006) and red ( P < .0001) foods. Yellow foods had less sugar than red foods ( P < .0001). Yellow foods were significantly higher in dietary fiber than red foods ( P = .001).

Conclusion:

The food rating color-coded system identifies food items with superior nutrition, and lower caloric density. The smartphone app, incorporating the system, has the potential to improve nutrition; reduce the risk of developing diabetes, hypertension, heart disease, and stroke; and improve public health.
Early Detection of Physical Activity for People With Type 1 Diabetes Mellitus
Authors: Dasanayake Isuru S. , Bevier Wendy C. , Castorino Kristin , Pinsker Jordan E. , Seborg Dale E. , Doyle Francis J. , Dassau Eyal
Published: July 2015

Background:

Early detection of exercise in individuals with type 1 diabetes mellitus (T1DM) may allow changes in therapy to prevent hypoglycemia. Currently there is limited experience with automated methods that detect the onset and end of exercise in this population. We sought to develop a novel method to quickly and reliably detect the onset and end of exercise in these individuals before significant changes in blood glucose (BG) occur.

Methods:

Sixteen adults with T1DM were studied as outpatients using a diary, accelerometer, heart rate monitor, and continuous glucose monitor for 2 days. These data were used to develop a principal component analysis based exercise detection method. Subjects also performed 60 and 30 minute exercise sessions at 30% and 50% predicted heart rate reserve (HRR), respectively. The detection method was applied to the exercise sessions to determine how quickly the detection of start and end of exercise occurred relative to change in BG.

Results:

Mild 30% HRR and moderate 50% HRR exercise onset was identified in 6 ± 3 and 5 ± 2 (mean ± SD) minutes, while completion was detected in 3 ± 8 and 6 ± 5 minutes, respectively. BG change from start of exercise to detection time was 1 ± 6 and −1 ± 3 mg/dL, and, from the end of exercise to detection time was 6 ± 4 and −17 ± 13 mg/dL, respectively, for the 2 exercise sessions. False positive and negative ratios were 4 ± 2% and 21 ± 22%.

Conclusions:

The novel method for exercise detection identified the onset and end of exercise in approximately 5 minutes, with an average BG change of only −6 mg/dL.

Background:

The Predictive Hypoglycemia Minimizer System (“Hypo Minimizer”), consisting of a zone model predictive controller (the “controller”) and a safety supervision module (the “safety module”), aims to mitigate hypoglycemia by preemptively modulating insulin delivery based on continuous glucose monitor (CGM) measurements. The “aggressiveness factor,” a pivotal variable in the system, governs the speed and magnitude of the controller’s insulin dosing characteristics in response to changes in CGM levels.

Methods:

Twelve adults with type 1 diabetes were studied in closed-loop in a clinical research center for approximately 24 hours. This analysis focused primarily on the effect of the aggressiveness factor on the automated insulin-delivery characteristics of the controller, and secondarily on the glucose control results.

Results:

As aggressiveness increased from “conservative” to “medium” to “aggressive,” the controller recommended less insulin (–3.3% vs –14.4% vs –19.5% relative to basal) with a higher frequency (5.3% vs 14.4% vs 20.3%) during the critical times when the CGM was reading 90-120 mg/dl and decreasing. Blood glucose analyses indicated that the most aggressive setting resulted in the most desirable combination of the least time spent <70 mg/dl and the most time spent 70-180 mg/dl, particularly in the overnight period. Hyperglycemia, diabetic ketoacidosis, or severe hypoglycemia did not occur with any of the aggressiveness values.

Conclusion:

The Hypo Minimizer’s controller took preemptive action to prevent hypoglycemia based on predicted changes in CGM glucose levels. The most aggressive setting was quickest to take action to reduce insulin delivery below basal and achieved the best glucose metrics.

Background and Purpose:

The modified Rankin Scale (mRS) is a common and resource-intensive measure of functional outcome in stroke-related conditions. In this observational prospective cohort feasibility study, mRS scores are generated using a patient-powered online survey and compared to scores obtained by structured telephonic interview.

Materials and Methods:

Fifty-one patients with subarachnoid hemorrhage (SAH) or their surrogates responded to an online survey following discharge from the hospital. These responses were used to generate an mRS score and then compared to blinded telephonic assessments by trained personnel. A weighted kappa (Kw) with confidence intervals (CIs) was calculated.

Results:

The Kw between the patient/surrogate and the trained personnel scores was 0.85 (95% CI, 0.74-0.95, P < .001).

Conclusion:

This study provides first evidence that patient/surrogate survey responses may be an efficient and reliable alternative to generate mRS scores compared to trained personnel after SAH.
Dynamic safety capability

We introduce the concept of “dynamic safety capability” (DSC) to describe an organization’s capacity to proactively change its core safety systems in environments characterized by change and uncertainty. Drawing on theories of dynamic capability in organizations, we define three core features of DSC: (a) sensing via scanning and attending to the future, (b) seizing via integrating complexity and, (c) transforming via enacting second-order change. We propose DSC is developed through organizational learning processes of experience, knowledge articulation, and knowledge codification. The features of DSC are integrated with major theories of safety and approaches to safety management. We discuss how organizational psychology can support the development of DSC through leadership and simulation activities.
Attentional Control and Suppressing Negative Thought Intrusions in Pathological Worry

Adaptive behavior relies on the ability to effectively and efficiently ignore irrelevant information, an important component of attentional control. The current research found that fundamental difficulties in ignoring irrelevant material are related to dispositional differences in trait propensity to worry, suggesting a core deficit in attentional control in high worriers. The degree of deficit in attentional control correlated with the degree of difficulty in suppressing negative thought intrusions in a worry assessment task. A cognitive training procedure utilizing a flanker task was used in an attempt to improve attentional control. Although the cognitive training was largely ineffective, improvements in attentional control were associated with improvements in the ability to suppress worry-related thought intrusions. Across two studies, the findings indicate that the inability to control worry-related negative thought intrusions is associated with a general deficiency in attentional control.
Mechanisms of Repetitive Thinking

Published: July 2015

Repetitive thinking about negative experience, such as worry and rumination, is increasingly recognized as a transdiagnostic process underlying various forms of psychopathology including anxiety and depression. Recent theoretical models have emphasized the role of impaired attentional control and the habitual nature of negative biases in the development and maintenance of pathological repetitive thought. In this introduction, we provide a brief overview of these theories and of how the articles in the special series provide experimental evidence concerning these basic mechanisms underlying rumination and worry, and their relation to clinical dysfunction. Together the research summarized in these articles instantiates these theoretical frameworks and provides convergent evidence confirming the value of adopting a transdiagnostic approach that focuses directly on fundamental mechanisms of psychopathology, instead of on diagnostic criteria.
