Cult of the icons in the East Slavs culture – customs, rituals and religious practices in the past and today

This article discusses the phenomenon of cult of icons in the East Slavic’s culture. The Slavic culture is ingrained in the orthodox tradition. This fact is reflected in a strong impact of religion on the life of society: customs, rituals and art. The icons are one of the most important elements of Orthodoxy Church and for that reason they are close associated with Russian culture. Despite prolonged atheisation, the Slavic culture is ingrained in the orthodox tradition and cult of the icons. It is noticeable not only in Russian churches, but also in ordinary life of believers. Majority of homes of Orthodox Christian have special space: "beautiful" corner with icons. Moreover, role of the icons emphasize in language: there is a lot of idiom and phrases connected with icons.

 

Kult ikon w kulturze wschodniosłowiańskiej – obrzędy, tradycje i praktyki religijne w przeszłości i dziś

Niniejsza praca koncentruje się wokół zagadnienia kultu ikon w kulturze wschodniosłowiańskiej, która od wieków zakorzeniona w tradycji prawosławnej. Znajduje to odzwierciedlenie w silnym wpływie religii na życie społeczne: obyczaje, tradycje czy sztukę. Nieodłącznym elementem prawosławia są zaś ikony i dlatego stały się one jedną z ważniejszych części kultury rosyjskiej. Widać to nie tylko w przestrzeni świątyni, ale również w życiu codziennym wiernych. Świadczy o tym m.in. praktyka wydzielania specjalnego miejsca dla kultu ikony tzw. „krasnogo ugła”. Ponadto, rolę ikon oddaje również język rosyjski, w którym istnieje wiele frazeologizmów związanych z ikonami.

Why it’s important for it to stop: Examining the mental health correlates of bullying and ill-treatment at work in a cohort study
Authors: Butterworth Peter , Leach Liana S , Kiely Kim M
Published: December 2015

Objective:

There is limited Australian information on the prevalence and mental health consequences of bullying and ill-treatment at work. The aims of this study were to use data from an ongoing Australian longitudinal cohort study to (1) compare different measures of workplace bullying, (2) estimate the prevalence of bullying and ill-treatment at work, (3) evaluate whether workplace bullying is distinct from other adverse work characteristics and (4) examine the unique contribution of workplace bullying to common mental disorders in mid-life.

Method:

The sample comprised 1466 participants (52% women) aged 52–58 from wave four of the Personality and Total Health (PATH) through Life study. Workplace bullying was assessed by a single item of self-labelling measure of bullying and a 15-item scale of bullying-related behaviours experienced in the past 6 months. Factor analysis the identified underlying factor structure of the behavioural bullying scale.

Results:

Current bullying was reported by 7.0% of respondents, while 46.4% of respondents reported that they had been bullied at some point in their working life. Person-related and work-related bullying behaviours were more common than violence and intimidation. The multi-dimensional scale of bullying behaviours had greater concordance with a single item of self-labelled bullying (Area Under the Curve = 0.88) than other adverse work characteristics (all Area Under the Curves < 0.67). Self-labelled bullying and scales reflecting person-related and work-related bullying were independent predictors of depression and/or anxiety.

Conclusion:

This study provides unique information on the prevalence and mental health impacts of workplace bullying and ill-treatment in Australia. Workplace bullying is a relatively common experience, and is associated with increased risk of depression and anxiety. Greater attention to identifying and preventing bullying and ill-treatment in the workplace is warranted.
Prospective rates of suicide attempts and nonsuicidal self-injury by young people with bipolar disorder participating in a psychotherapy study
Authors: Inder Maree L , Crowe Marie T , Luty Suzanne E , Carter Janet D , Moor Stephanie , Frampton Christopher M , Joyce Peter R
Published: December 2015

Objective:

Bipolar disorder is a chronic relapsing disorder associated with high rates of suicide, suicide attempts and nonsuicidal self-injury. The study aimed to prospectively identify the rates of suicide attempts and nonsuicidal self-injury in young people participating in an adjunctive randomised controlled psychotherapy for bipolar disorder and to identify differences in individuals who engaged in nonsuicidal self-injury, made suicide attempts or did both.

Method:

In all, 100 participants aged 15–36 years with bipolar disorder received 78 weeks of psychotherapy and were followed up for a further 78 weeks. Data were collected using the Longitudinal Interval Follow-up Evaluation.

Results:

Suicide attempts reduced from 11% at baseline to 1% at the end of follow-up (week 156). Similarly, self-harm reduced from 15% at baseline to 7% at the end of follow-up. Individuals who engaged in both nonsuicidal self-injury and made suicide attempts differed from those with who only made suicide attempts, engaged in nonsuicidal self-injury or did neither. They were characterised by a younger age of illness onset and higher comorbidity.

Conclusion:

Adjunctive intensive psychotherapy may be effective in reducing suicide attempts and nonsuicidal self-injury and warrants further attention. Particular attention needs to be paid to individuals with early age of onset of bipolar disorder.

Published: December 2015

Objective:

To describe the study design of Young Minds Matter: The second Australian Child and Adolescent Survey of Mental Health and Wellbeing. The aims of the study, sample design, development of survey content, field procedures and final questionnaires are detailed.

Method:

During 2013–2014, a national household survey of the mental health and wellbeing of young people was conducted involving a sample of 6310 families selected at random from across Australia. The survey included a face-to-face diagnostic interview with parents/carers of 4- to 17-year-olds and a self-report questionnaire completed by young people aged 11–17 years.

Results:

The overall response rate to the survey was 55% with 6310 parents/carers of eligible households participating in the survey. In addition, 2967 or 89% of young people aged 11–17 years in these participating households completed a questionnaire. The survey sample was found to be broadly representative of the Australian population on major demographic characteristics when compared with data from the Census of Population and Housing. However, adjustments were made for an over-representation of younger children aged 4 to 7 years and also families with more than one eligible child in the household.

Conclusion:

Young Minds Matter provides updated national prevalence estimates of common child and adolescent mental disorders, describes patterns of service use and will help to guide future decisions in the development of policy and provision of mental health services for children and adolescents. Advancements in interviewing methodology, addition of a data linkage component and informed content development contributed to improved breadth and quality of the data collected.
A literature review of heart rate variability in depressive and bipolar disorders
Authors: Bassett Darryl
Published: December 2015

Objective:

Autonomic nervous system dysfunction has the potential to adversely impact general medical health and is known to exist in a number of psychiatric disorders. It reflects alterations in the function of several regions of the central nervous system. Measurement of heart rate variability provides a non-invasive tool for studying autonomic function. While the literature relating to the technical process of heart rate variability and aspects of depressive disorders has been reviewed in the past, research relating to both depressive and bipolar disorders has not been comprehensively reviewed. This paper critically considers the published research in heart rate variability in both depressive and bipolar affective disorders.

Method:

A literature search using Medline, EMBASE, PsycINFO, ProQuest Psychology and references included in published literature was conducted using the following keywords: ‘ heart rate variability and autonomic, combined with depression, depressive disorder, bipolar, mania and sleep’.

Results:

The evidence demonstrates that, using heart rate variability measures, significant distortions of autonomic function are evident in both depressive and bipolar disorders and from most of their pharmacological treatments.

Conclusion:

The autonomic dysfunction evident in both unipolar and bipolar affective disorders, and many psychotropic medications, has significant implications for our understanding of the neurophysiology of these disorders, their treatment and associated general health.
Examining the association between social cognition and functioning in individuals at ultra-high risk for psychosis
Authors: Cotter Jack , Bartholomeusz Cali , Papas Alicia , Allott Kelly , Nelson Barnaby , Yung Alison R , Thompson Andrew
Published: December 2015

Objective:

Social and role functioning are compromised for the majority of individuals at ultra-high risk of psychosis, and it is important to identify factors that contribute to this functional decline. This study aimed to investigate social cognitive abilities, which have previously been linked to functioning in schizophrenia, as potential factors that impact social, role and global functioning in ultra-high risk patients.

Method:

A total of 30 ultra-high risk patients were recruited from an established at-risk clinical service in Melbourne, Australia, and completed a battery of social cognitive, neurocognitive, clinical and functioning measures. We examined the relationships between all four core domains of social cognition (emotion recognition, theory of mind, social perception and attributional style), neurocognitive, clinical and demographic variables with three measures of functioning (the Global Functioning Social and Role scales and the Social and Occupational Functioning Assessment Scale) using correlational and multiple regression analyses.

Results:

Performance on a visual theory of mind task (visual jokes task) was significantly correlated with both concurrent role ( r = 0.425, p = 0.019) and global functioning ( r = 0.540, p = 0.002). In multivariate analyses, it also accounted for unique variance in global, but not role functioning after adjusting for negative symptoms and stress. Social functioning was not associated with performance on any of the social cognition tasks.

Conclusion:

Among specific social cognitive abilities, only a test of theory of mind was associated with functioning in our ultra-high risk sample. Further longitudinal research is needed to examine the impact of social cognitive deficits on long-term functional outcome in the ultra-high risk group. Identifying social cognitive abilities that significantly impact functioning is important to inform the development of targeted intervention programmes for ultra-high risk individuals.
Last whales: Eschatology, extinction, and the cetacean imaginary in Winton and Pash
Authors: Huggan Graham
Published: December 2015

Few of the earth’s creatures capture the popular imagination quite like the whale, which has come to serve as an ambivalent figure for both salvation and perdition, whether the moral dramas that unfold around it are seen in religious (eschatological) or scientific (ecological) terms. Whales are at once signifiers for extinction, pointing to the threat of planetary destruction, and signifiers for redemption, in which the ongoing environmentalist campaign for protection doubles as a human struggle to save us from ourselves. This article looks at two contemporary Australian literary texts, Tim Winton’s Shallows (1985) and Chris Pash’s The Last Whale (2008), both of which explore competing extinction scenarios: the extinction of whales; the extinction of the whaling industry; and the extinction of whaling as a way of life. Given the further possibility of human self-extinction, the article argues that a new cetacean imaginary is needed in which whales are seen as complex manifestations of a life that co-exists with humanity, but is neither reducible to human understandings of history nor to the various futures — or non-futures — that human beings might imagine for themselves.

Authors: Shin SE , Moon SM , Lee DY , Lee DS , Bae DH
Published: December 2015

To fabricate large-scale multi-walled carbon nanotube-reinforced aluminum matrix composites, in this study, nanocomposites powder is successfully consolidated with simple processing methods. Ball milling is used to disperse multi-walled carbon nanotubes in the aluminum alloy 2024 matrix, and sequential cold press, hot press, and sintering techniques are selected for fabricating fully dense samples. As a result, an aluminum alloy 2024 composite with 4 vol.% multi-walled carbon nanotubes shows a yield strength of ∼700 MPa and an elongation to failure of 1.5% with Young’s modulus of 86.4 GPa. The large-scale composite can be used for automobile parts such as swash plates or piston heads.
The Limits of Hate: Japanese Prisoners on US Submarines during the Second World War
Authors: Sturma Michael
Published: December 2015

The Pacific War is frequently characterized as a ‘race war’ and a ‘war without mercy’. The experience of Japanese prisoners on American submarines, however, suggests that hatred could often quickly be overcome once combatants spent time in close proximity. The confined space of submarines made a degree of interaction between prisoners and captors unavoidable. Through a series of case studies, the evidence suggests that submariners sometimes contravened the Geneva Convention in extracting work and obtaining information from prisoners. On the other hand, it appears that relations between prisoners and captors were for the most part amicable and at times mutually supportive. Although these relationships were manifestly unequal, occasionally prisoners exercised a degree of influence over submariners’ fates.
MALT1 Inhibition of Oral Carcinoma Cell Invasion and ERK/MAPK Activation

Published: December 2015

The expression of mucosa-associated lymphoid tissue 1 (MALT1) that activates nuclear factor (NF)–κB in lymphocyte lineages is rapidly inactivated in oral carcinoma cells at the invasive front and the patients with worst prognosis. However, its mechanism to accelerate carcinoma progression remains unknown, and this study was carried out to examine the role in invasion. HSC2 oral carcinoma cells stably expressing wild-type MALT1 (wtMALT1) reduced the invasion of basement membrane matrices and collagen gels, and the dominant-negative form (∆MALT1)–expressing cells aggressively invaded into collagen gels. MALT1 decelerated proliferation and migration of cells and downregulated expression of matrix metalloproteinase 2 and 9, which were confirmed by short interfering RNA transfections. Reporter assays and immunoblot analysis showed that MALT1 does not affect the NF-κB pathway but inhibits ERK/MAPK activation. This was confirmed by endogenous MALT1 expression in oral carcinoma cell lines. Orthotopic implantation of ∆MALT1-expressing HSC2 cells in mice grew rapid expansive and invasive tongue tumors in contrast to an absence of tumor formation by wtMALT1-expressing cells. These results demonstrate that MALT1 suppresses oral carcinoma invasion by inhibiting proliferation, migration, and extracellular matrix degradation and that the ERK/MAPK pathway is a target of MALT1 and further suggests a role as a suppressor of carcinoma progression.
Dislocated Tongue Muscle Attachment and Cleft Palate Formation
Authors: Kouskoura T. , El Fersioui Y. , Angelini M. , Graf D. , Katsaros C. , Chiquet M.
Published: December 2015

In Pierre Robin sequence, a retracted tongue due to micrognathia is thought to physically obstruct palatal shelf elevation and thereby cause cleft palate. However, micrognathia is not always associated with palatal clefting. Here, by using the Bmp7-null mouse model presenting with cleft palate and severe micrognathia, we provide the first causative mechanism linking the two. In wild-type embryos, the genioglossus muscle, which mediates tongue protrusion, originates from the rostral process of Meckel’s cartilage and later from the mandibular symphysis, with 2 tendons positive for Scleraxis messenger RNA. In E13.5 Bmp7-null embryos, a rostral process failed to form, and a mandibular symphysis was absent at E17.5. Consequently, the genioglossus muscle fibers were diverted toward the lingual surface of Meckel’s cartilage and mandibles, where they attached in an aponeurosis that ectopically expressed Scleraxis. The deflection of genioglossus fibers from the anterior-posterior toward the medial-lateral axis alters their direction of contraction and necessarily compromises tongue protrusion. Since this muscle abnormality precedes palatal shelf elevation, it is likely to contribute to clefting. In contrast, embryos with a cranial mesenchyme-specific deletion of Bmp7 ( Bmp7:Wnt1-Cre) exhibited some degree of micrognathia but no cleft palate. In these embryos, a rostral process was present, indicating that mesenchyme-derived Bmp7 is dispensable for its formation. Moreover, the genioglossus appeared normal in Bmp7:Wnt1-Cre embryos, further supporting a role of aberrant tongue muscle attachment in palatal clefting. We thus propose that in Pierre Robin sequence, palatal shelf elevation is not impaired simply by physical obstruction by the tongue but by a specific developmental defect that leads to functional changes in tongue movements.

Published: December 2015

This was a prospective cohort study evaluating 126,805 individuals with diabetes and periodontal disease receiving care at all Veterans Administration medical centers and clinics in the United States from 2005 through 2012. The exposures were periodontal treatment at baseline (PT0) and at follow-up (PT2). The outcomes were change in HbA1c following initial treatment (ΔHbA1c1) and follow-up treatment (ΔHbA1c2), and diabetes control was defined as HbA1c at <7% and <9% following initial and follow-up treatment, respectively. Marginal structural models were used to account for potential confounding and selection bias. The objective was to evaluate the impact of long-term treatment of periodontal disease on glycemic control among individuals with type 2 diabetes. Participants were 64 y old on average, 97% were men, and 71% were white. At baseline, the average diabetes duration was 4 y, 12% of participants were receiving insulin, and 60% had HbA1c <7%. After an average 1.7 y of follow-up, the mean HbA1c increased from 7.03% to 7.21%. About 29.4% of participants attended their periodontal maintenance visit following baseline. Periodontal treatment at baseline and follow-up reduced HbA1c by −0.02% and −0.074%, respectively. Treatment at follow-up increased the likelihood of individuals achieving diabetes control by 5% and 3% at the HbA1c <7% and HbA1c <9% thresholds, respectively, and was observed even among never smokers. HbA1c reduction after periodontal treatment at follow-up was greater (ΔHbA1c2 = −0.25%) among individuals with higher baseline HbA1c. Long-term periodontal care provided in a clinical setting improved long-term glycemic control among individuals with type 2 diabetes and periodontal disease.

Self-assembled nanolayering structures have been reported in resin-dentin interfaces created by adhesives that contain 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP). These structures have been hypothesized to contribute to bond durability. The objective of the present study was to determine the extent of nanolayering in resin-dentin interfaces after application of commercialized 10-MDP-containing self-etch and universal adhesives to human dentin. Seven commercialized adhesives were examined: Adhese Universal (Ivoclar-Vivadent), All-Bond Universal (Bisco, Inc.), Clearfil SE Bond 2, Clearfil S3 Bond Plus, Clearfil Universal Bond (all from Kuraray Noritake Dental Inc.), G-Premio Bond (GC Corp.), and Scotchbond Universal (3M ESPE). Each adhesive was applied in the self-etch mode on midcoronal dentin according to the respective manufacturer’s instructions. Bonded specimens ( n = 6) were covered with flowable resin composite, processed for transmission electron microscopy, and examined at 30 random sites without staining. Thin-film glancing angle X-ray diffraction (XRD) was used to detect the characteristic peaks exhibited by nanolayering ( n = 4). The control consisted of 15%wt, 10%wt, and 5%wt 10-MDP (DM Healthcare Products, Inc.) dissolved in a mixed solvent (ethanol and water weight ratio 9:8, with photoinitiators). Experimental primers were applied to dentin for 20 s, covered with hydrophobic resin layer, and examined in the same manner. Profuse nanolayering with highly ordered periodicity (~3.7 nm wide) was observed adjacent to partially dissolved apatite crystallites in dentin treated with the 15% 10-MDP primer. Three peaks in the 2θ range of 2.40° (3.68 nm), 4.78° (1.85 nm), and 7.18° (1.23 nm) were identified from thin-film XRD. Reduction in the extent of nanolayering was observed in the 10% and 5% 10-MDP experimental primer-dentin interface along with lower intensity XRD peaks. Nanolayering and characteristic XRD peaks were rarely observed in specimens prepared from the commercialized adhesives. The sparsity of nanolayering in resin-dentin interfaces created by commercialized adhesives challenges its clinical effectiveness as a mechanism for improving bond longevity in dentin bonding.
Simulation-optimization model for one-way traffic reconfiguration
Authors: Peng Zixuan , Guan Feng , Wang Keming , Li Ting , Yao Baozhen
Published: December 2015

One-way traffic is a kind of traffic management measure with less investment, simple operation, and obvious effects. Considering some irrational one-way lane configurations currently in practice, a bi-level optimization programming model is proposed in this paper. The decision-making variable of the upper level model is the scheme of one-way traffic reconfiguration, and the optimization target is to minimize the total travel time. The lower level programming is an equilibrium traffic assignment model. The Shuffled Complex Evolution Algorithm (SCE-UA) and VisSim simulation are applied for the upper and lower models, respectively. A numerical test based on Dalian Harbour Plaza is employed to validate the proposed model. In the test, the effects of the current scheme, the scheme solved by the bi-level model using the SCE-UA and Frank-Wolfe algorithm, and the scheme proposed by this paper (simulation-optimization) are compared. As the results show, the bi-level programming model in this paper can perform well in reducing the total travel time of travelers and in improving traffic efficiency.
Finding their way to heaven: Women, self-narratives and Catholicism in Quito, Ecuador
Authors: Calderón Muñoz María
Published: December 2015

In this paper I look at personal histories of middle class women who belong to a Catholic group in Quito, Ecuador. Using a poststructuralist definition of the subject I explore the reasons why these women intentionally break the Church’s rules and make decisions that constitute sins. I argue that in order to understand their disobedience to Catholicism, it is necessary to contextualise their decisions. Their choices can be explained if we look at these women’s lives not only as Catholics but also as belonging to a social class and ethnicity and as members of a family. In this paper I want to explore how these different affiliations are combined and why and when one is prioritised over the others. In other words, how Catholic women adapt religion to fit in with their other needs. Ultimately, this paper will provide insights on the concept of agency and decision-making.
The Structural Invisibility of Outsiders: The Role of Migrant Labour in the Meat-Processing Industry
Authors: Lever John , Milbourne Paul
Published: December 2015

This article examines the role of migrant workers in meat-processing factories in the UK. Drawing on materials from mixed methods research in a number of case study towns across Wales, we explore the structural and spatial processes that position migrant workers as outsiders. While state policy and immigration controls are often presented as a way of protecting migrant workers from work-based exploitation and ensuring jobs for British workers, our research highlights that the situation ‘on the ground’ is more complex. We argue that ‘self-exploitation’ among the migrant workforce is linked to the strategies of employers and the organisation of work, and that hyper-flexible work patterns have reinforced the spatial and social invisibilities of migrant workers in this sector. While this creates problems for migrant workers, we conclude that it is beneficial to supermarkets looking to supply consumers with the regular supply of cheap food to which they have become accustomed.
Money-Related Meanings and Practices in Low-Income and Poor Families
Authors: Daly Mary
Published: December 2015

This article focuses on the meanings and repertoires of action associated with money in low-income and poverty circumstances. Based on interviews with 51 people, the analysis reveals how people on a low income actively engage with money as a way of situating themselves in their complex worlds. Money is investigated at two levels: praxis and orientation regarding spending, and as part of self-identity. In regard to spending, people displayed two main repertoires: one was functional (viewing money as a way of meeting material need) and the second relational (with money interpreted in regard to relationships and upholding of personal and familial values). These repertoires in turn link into self-understanding and world view. For people in poverty and low income, money can be a disabler, detracting from a valued identity and sense of future but a counter, more positive, orientation normalises lack of money, by reference to skills and character development and core values and relationships. The research as a whole underlines the complexity of money in low-income or poverty settings, the agency and creativity which people bring to its use and the diverse meanings they invest it with.
Chronic Absenteeism in the Classroom Context: Effects on Achievement
Authors: Gottfried Michael A.
Published: December 2015

Although educational policy makers uphold that chronic absenteeism (missing 10% or more of the school year) is damaging to students’ schooling outcomes, there is little empirical research to match. This study considers the role of spillover effects of chronic absenteeism on classmates’ achievement. It does so by utilizing a large-scale administrative urban district data set of elementary schoolchildren—a sample of students where the rates of chronic absenteeism are expected to be higher compared with the national average. The results show that students suffer academically from having chronically absent classmates—as exhibited across both reading and math testing outcomes. Chronic absenteeism not only had a damaging effect on those individuals missing excessive school days but also has the potential to reduce outcomes for others in the same educational setting.
For Profit, For Success, For Black Men: A Review of Literature on Urban For-Profit Colleges and Universities
Authors: Boykin Tiffany F.
Published: December 2015

In the last 20 years, the U.S. higher education system has witnessed the tremendous growth of for-profit colleges and universities (FPCUs). In fact, FPCUs have quickly become the fastest growing segment of postsecondary education. With innovative practices and alternative delivery of educational services, FPCUs have established a considerable pipeline for minority students, especially Blacks. This article presents research and literature on the phenomenon of the rising FPCU and what it represents for racial minorities, especially Black males. Recommendations for practice and policy for Black male student success are offered.
Sharing Tourism Experiences
Authors: Kim Jeongmi (Jamie) , Fesenmaier Daniel R.
Published: December 2015

Social media changes how travelers see and experience their trip. This study first proposes a framework which describes the relationships between social media and the tourism experience. Based upon this framework, it then examines the impact of social media when travelers share their emotions and perceptions after the trip. The results of the study confirm that sharing positive experiences post trip increases travelers’ positive affect while decreasing negative affect and therefore leads toward more positive overall evaluations. Further, we find that sharing unsatisfactory travel experiences through social media helps to reduce negative perceptions of the trip, which, in turn, enhances posttrip evaluations.
Market-Oriented Destination Marketing
Authors: Line Nathaniel D. , Wang Youcheng
Published: December 2015

As competition among destinations has intensified, researchers have increasingly advocated for a market-oriented approach to destination marketing. Unfortunately, the unique stakeholder structure of the destination marketing environment precludes a direct application of the traditional market orientation paradigm to this domain. Accordingly, the purpose of this research is to empirically develop an operational definition of the market orientation construct that can be applied to destination marketing organizations. Based on the tenets of stakeholder theory, this research proposes a multiple-stakeholder view of the marketing concept and develops its attendant operational construct. Referred to herein as a multistakeholder market orientation (MSMO), this construct is proposed and operationalized as reflective of the extent to which a destination marketing organization (DMO) implements the marketing concept across the stakeholder spectrum. The nomological validity of this construct is established by testing the effect of the proposed MSMO construct on DMO performance.
Higher-order sliding mode based lateral guidance for unmanned aerial vehicles
Authors: Ali Syed Ussama , Samar Raza , Shah M Zamurad , Bhatti Aamer I , Munawar Khalid
Published: December 2015

A nonlinear sliding mode based scheme is developed for lateral guidance of unmanned aerial vehicles. The guidance and control system is considered as an inner and outer loop design problem, the outer guidance loop generates commands for the inner control loop to follow. Control loop dynamics is considered during derivation of the guidance logic, along with saturation constraints on the guidance commands. A nonlinear sliding manifold is selected for guidance logic design, the guidance loop generates bank angle commands for the inner roll control loop to follow. The real twisting algorithm, a higher order sliding mode algorithm is used for guidance logic design. Existence of the sliding mode along with boundedness of the guidance command is proved to ensure that controls are not saturated for large track errors. The proposed logic also contains an element of anticipatory or feed-forward control, which enables tight tracking for sharply curving paths. Efficacy of the proposed method is verified by flight testing on a scaled YAK-54 unmanned aerial vehicle. Flight results demonstrate robustness and effectiveness of the proposed guidance scheme in the presence of disturbances.
Heartbeat classification using different classifiers with non-linear feature extraction
Authors: Li Hongqiang , Feng Xiuli , Cao Lu , Zhang Cheng , Tang Chunxiao , Li Enbang , Liang Huan , Chen Xuelong
Published: December 2015

The electrocardiogram (ECG) is an important technique for heart disease diagnosis. This paper proposes a novel method for ECG beat classification. Several important issues exist in the ECG beat classification, which, if suitably addressed, may lead to development of more robust and efficient recognizers. Some of these issues include feature extraction, choice of classification approach and optimization. A new method for non-linear feature extraction of ECG signals based on empirical mode decomposition (EMD), approximate entropy (ApEn) and wavelet packet entropy is presented. The proposed method first uses EMD to decompose ECG signals into a finite number of intrinsic mode functions (IMFs), calculates the ApEn of IMFs as one feature and then obtains the wavelet packet entropy of wavelet packet coefficients as another feature. The two features are regarded as a feature vector. The support vector machine (SVM) and probabilistic neural network (PNN) are used for beat classification. The particle swarm optimization algorithm is used to optimize parameters of the PNN and SVM. The performance of the SVM classifier is slightly superior to that of the PNN classifier with 98.6% accuracy.

Background: Well‐known risk factors for Clostridium difficile infection (CDI) are exposure to antibiotics and gastric acid suppressants. Recent studies have provided some evidence of an association between hypovitaminosis D and the risk of CDI. Therefore, this meta‐analysis aimed to pool all the existing evidence to investigate the association between 25‐hydroxyvitamin D (25[OH]D) and CDI. Methods: A systematic search was conducted in 3 databases (PubMed, Embase, and Web of Sciences) for epidemiological studies that examined the association between mean 25(OH)D concentrations and CDI as well as between 25(OH)D status and CDI severity or recurrence. 25(OH)D status was defined as “lower” or “higher” at a threshold concentration of <20 or ≥20 ng/mL, respectively. Pooled effect sizes were computed using the inverse variance heterogeneity model of meta‐analysis. Results: Eight publications (n = 4479 patients) were included in the meta‐analysis. The mean concentration of 25(OH)D in patients with CDI was 3.54 ng/mL (95% confidence interval [CI], 0.39–6.89 ng/mL) lower than in patients without CDI. Patients with lower 25(OH)D status had a higher odds (odds ratio [OR], 1.61; 95% CI, 1.02–2.53) of developing severe CDI compared with those with a higher 25(OH)D status. No significant association was found between 25(OH)D status and CDI recurrence. Conclusion: The results of this meta‐analysis suggest that lower mean concentrations of 25(OH)D were associated with CDI. A lower 25(OH)D status increased the odds of severe CDI but not of CDI recurrence.
Georg Lukács as a communications scholar: cultural and digital labour in the context of Lukács’ Ontology of Social Being
Authors: Fuchs Christian
Published: December 2015

The task of this work is to apply thoughts from Georg Lukács’ final book, the Ontology of Social Being, for the theoretical analysis of cultural and digital labour. It discusses Lukács’ concepts of work and communication and relates them to the analysis of cultural and digital work. It also analyses his conception of the relation of labour and ideology and points out how we can make use of it for critically understanding social media ideologies. Lukács opposes the dualist separation of the realms of work and ideas. He introduces in this context the notion of teleological positing that allows us to better understand cultural and digital labour as well as associated ideologies, such as the engaging/connecting/sharing-ideology, today. The analysis shows that Lukács’ Ontology is in the age of Facebook, YouTube and Twitter, still a very relevant book, although it has thus far not received the attention that it deserves. This article also introduces the Ontology’s main ideas on work and culture, which is important because large parts of the book have not been translated from the German original into English. Lukács’ notion of teleological positing is crucial for understanding the common features of the economy and culture.

Owing to the rapid growth of the World Wide Web, the number of documents that can be accessed via the Internet explosively increases with each passing day. Considering news portals in particular, sometimes documents related to categories such as technology, sports and politics seem to be in the wrong category or documents are located in a generic category called others. At this point, text categorization (TC), which is generally addressed as a supervised learning task is needed. Although there are substantial number of studies conducted on TC in other languages, the number of studies conducted in Turkish is very limited owing to the lack of accessibility and usability of datasets created. In this paper, a new dataset named TTC-3600, which can be widely used in studies of TC of Turkish news and articles, is created. TTC-3600 is a well-documented dataset and its file formats are compatible with well-known text mining tools. Five widely used classifiers within the field of TC and two feature selection methods are evaluated on TTC-3600. The experimental results indicate that the best accuracy criterion value 91.03% is obtained with the combination of Random Forest classifier and attribute ranking-based feature selection method in all comparisons performed after pre-processing and feature selection steps. The publicly available TTC-3600 dataset and the experimental results of this study can be utilized in comparative experiments by other researchers.
Associations and Intervening Mechanisms Between Family Structure and Young Children’s Obesity
Authors: Augustine Jennifer March , Kimbro Rachel Tolbert
Published: December 2015

This study examined the links between different family structures—capturing type and stability thereof—and preschool-aged children’s likelihood of being obese. We build on the limited number of studies that have pursued this topic by using a large, nationally representative sample of preschool-aged children from the Early Childhood Longitudinal Survey–Birth Cohort ( n = 8,350) and exploring a wide range of mechanisms to explain these links. Results revealed that, compared with young children with stably married parents, children in cohabiting- and single-parent families that experienced a prior family structure change were more likely to be obese, except for children in single-parent families born to married parents. Children in step, stably single, and stably cohabiting families were at no greater risk of obesity. These patterns were largely driven by female children, for whom the effects of family structure were most robust. None of the 11 tested mechanisms explained such patterns.

Long-acting injectable (LAI) drug suspensions consist of drug nano-/microcrystals suspended in an aqueous vehicle and enable prolonged therapeutic drug exposure up to several months. The examination of injection site reactions (ISRs) to the intramuscular (IM) injection of LAI suspensions is relevant not only from a safety perspective but also for the understanding of the pharmacokinetics. The aim of this study was to perform a multilevel temporal characterization of the local and lymphatic histopathological/immunological alterations triggered by the IM injection of an LAI paliperidone palmitate suspension and an analog polystyrene suspension in rats and identify critical time points and parameters with regard to the host response. The ISRs showed a moderate to marked chronic granulomatous inflammation, which was mediated by multiple cyto-/chemokines, including interleukin-1β, monocyte Chemoattractant Protein-1, and vascular endothelial growth factor. Lymphatic uptake and lymph node retention of nano-/microparticles were observed, but the contribution to the drug absorption was negligible. A simple image analysis procedure and empirical model were proposed for the accurate evaluation of the depot geometry, cell infiltration, and vascularization. This study was designed as a reference for the evaluation and comparison of future LAIs and to support the mechanistic modeling of the formulation–physiology interplay regulating the drug absorption from LAIs.
The Potential of Minipigs in the Development of Anticancer Therapeutics
Authors: Mahl Andreas , Dincer Zuhal , Heining Peter
Published: December 2015

Minipigs are increasingly being used as an alternative to dog or monkey in nonclinical safety testing of pharmaceuticals since they share similar anatomical and physiological characteristics to humans. Integrative assessment of pharmacodynamic and pharmacokinetic data sets of drug candidates from in silico, in vitro, and in vivo investigations form the basis for selecting the most relevant nonrodent species for toxicology studies. Developing anticancer therapeutics represents a special challenge for species selection due to their effects on multiple organ systems. The toxicological profile of anticancer drugs can be associated with steep dose–response curves, especially due to dose-limiting toxicity on the alimentary, hematopoietic, and immune systems. Selection of an appropriate species for toxicology studies is of importance to avoid an inappropriately low (without benefit for the late-stage cancer patient) or high clinical starting dose (with a risk of unexpected adverse reactions). Although the minipig has been the preferred species to develop drugs applied topically, it is only rarely used in anticancer drug development compared to dog and monkey. In this context, we discuss the potential of minipigs in anticancer drug development with examples of programs for oral and dermal administration, intravascular application in drug-eluting stents, and local chemotherapy (chemoembolization).
Lymph Node Yield as a Predictor of Survival in Pathologically Node Negative Oral Cavity Carcinoma
Authors: Lemieux Aaron , Kedarisetty Suraj , Raju Sharat , Orosco Ryan , Coffey Charles
Published: December 2015

Objective

Even after a pathologically node‐negative (pN0) neck dissection for oral cavity squamous cell carcinoma (SCC), patients may develop regional recurrence. In this study, we (1) hypothesize that an increased number of lymph nodes removed (lymph node yield) in patients with pN0 oral SCC predicts improved survival and (2) explore predictors of survival in these patients using a multivariable model.

Study Design

Case series with chart review.

Setting

Administrative database analysis.

Subjects and Methods

The SEER database was queried for patients diagnosed with all‐stage oral cavity SCC between 1988 and 2009 who were determined to be pN0 after elective lymph node dissection. Demographic and treatment variables were extracted. The association of lymph node yield with 5‐year all‐cause survival was studied with multivariable survival analyses.

Results

A total of 4341 patients with pN0 oral SCC were included in this study. The 2 highest lymph node yield quartiles (representing >22 nodes removed) were found to be significant predictors of overall survival (22‐35 nodes: hazard ratio [HR] = 0.854, P =. 031; 36‐98 nodes: HR = 0.827, P =. 010). Each additional lymph node removed during neck dissection was associated with increased survival (HR = 0.995, P =. 022).

Conclusion

These data suggest that patients with oral SCC undergoing elective neck dissection may experience an overall survival benefit associated with greater lymph node yield. Mechanisms behind the demonstrated survival advantage are unknown. Larger nodal dissections may remove a greater burden of microscopic metastatic disease, diminishing the likelihood of recurrence. Lymph node yield may serve as an objective measure of the adequacy of lymphadenectomy.
Rock, water, air and fire: Foregrounding the elements in the Gibraltar-Spain dispute
Authors: Squire Rachael
Published: December 2015

Through the case study of the contested British Overseas Territory of Gibraltar, this paper contributes to discussions on ‘territorial volumes’ by exploring the role of the ‘elemental’ in the protracted sovereignty dispute between Spain and Gibraltar. Drawing on scholarship by Elden, Adey, McCormack and others in political and cultural geography, the paper highlights the value of foregrounding the elements of rock, water, air and fire (in the form of the sun) in attempts to understand the tensions between Gibraltar and Spain whilst also demonstrating the significant intersections between the elemental and the human body. Whilst avoiding the snares of environmental determinism, the paper makes the case for an elemental ontology that functions through and with the proclivities and molecular specificities of the elements in order to better understand the construct of the territorial volume, the relationship between elemental and bodily volumes, and the site specific geopolitical realities, fractures and possibilities that are laid bare as the elements are unearthed.
