Authors: Pallangyo Eunice , Mbekenga Columba , Olsson Pia , Källestål Carina 
Published: July 2017

Background: Globally, postpartum care (PPC) is a neglected part of maternal and neonatal health, despite 50% of maternal deaths occuring in the first weeks after childbirth. Aim: The study aimed to assess knowledge, attitudes and practices among providers of PPC in government institutions in two low-resource suburbs of Dar es Salaam: Ilala and Temeke. Methods: Health professionals (n=149) at all levels of care completed a knowledge and attitudes questionnaire. A checklist was used to observe 25 health professionals at reproductive and child health units, and 38 mothers were interviewed on exit. χ2- and logistic regression tests were used to analyse the outcomes. Field notes were analysed qualitatively. Findings: Overall, 64% of health professionals had high knowledge and most had positive attitudes towards PPC. Level of education was found to be positively associated with positive attitudes towards PPC (OR=2.5 CI 95% 1.03–6.13). PPC consultations with mothers and newborns during the first week after childbirth were found to be few or nonexistent. Mothers who came with newborns for BCG immunisation were mostly satisfied with the services. Conclusion: Quality improvement is required at the structure and process levels of the health system in order to provide holistic PPC consultations.
The influence of implementing nurse-led enteral nutrition guidelines on care delivery in the critically ill: a cohort study
Authors: Kalaldeh Mahmoud Al 
Published: July 2017

Aim: To identify how implementation of nurse-led enteral nutrition (EN) guidelines influenced nurses' care delivery in an intensive care unit. Methods: This multi-centre prospective observational study introduced an educational programme for 127 nurses on evidence-based ASPEN guidelines for enteral nutrition. Pre- and post-intervention observation assessed adherence to the guidelines through reporting of care delivered. Results: A total of 192 patients from 80 controls and 112 interventions were observed; gastric residual volume was evaluated in 67.9% of intervention patients compared with 26.3% of controls (p=0.001). The intervention group was more likely to maintain head-of-bed elevation, check tube placement and use continuous feeding and chlorhexidine mouthwash. Intervention patients received nutrition earlier than controls, and they had fewer feeding interruptions (median of 12.66 vs 32.18 hours, p<0.001) and higher caloric attainment (68.8% vs 50%, p=0.015). Conclusions: The guidelines improved nursing adherence to nutritional assessment measures.
The effects of digital games on hedonic, eudaimonic and telic entertainment experiences
Authors: Kümpel Anna Sophie , Unkel Julian 
Published: July 2017

Abstract
This study extends current research on media entertainment by examining the effects of (perceived) game characteristics on hedonic, eudaimonic and telic entertainment experiences. Furthermore, differentiating between meaningful and non-meaningful games, we investigated whether these game types lead to the experience of different gaming-related emotions and what determines their discontinuation. Building on an online survey with 325 German gamers, we found a game’s narrative, its mechanics, the satisfaction of basic needs and perceived cognitive and affective challenge to be associated with the three entertainment experiences in distinct ways. In addition, the results suggest that meaningful and non-meaningful games induce specific emotions and are discontinued due to different considerations. The study furthers our theoretical understanding of (interactive) media entertainment and shows how the interplay of factors internal and external to a game shapes the overall game entertainment experience.
The golden (hands) rule: Exploring user experiences with gamepad and natural-user interfaces in popular video games
Authors: Bowman Nicholas David , Pietschmann Daniel , Liebold Benny 
Published: July 2017

Abstract
This research report sought to understand how gamers experienced recent gaming sessions using traditional game controllers (gamepads) or natural user interfaces (NUIs, such as the Nintendo Wiimote). A secondary qualitative analysis of N=238 open-ended comments to a larger game controller experience survey were analysed for emergent themes, with χ2 tests used to compare the frequency of their mention between the two controller types. While the same eleven discussion themes emerged when players described either gamepad or NUI experiences, participants discussing gamepads were more likely to comment on the controller’s precision, comfort, success using the controller, and their past experience with the controller. Likewise, participants discussing NUIs were more likely to comment on the controller’s lack of precision, feeling unnatural, having less success during the game session, and seeing the controller as more novel. No differences in controller simplicity or the overall enjoyment were found. Additionally, game genre differences were found suggesting shooting games (first- and third-person shooters) to be more frequently played with gamepads and sports games to be more frequently played with NUIs, and gamepad session were as much as 50 per cent longer on average. This research supports and extends prior findings which suggest that NUIs might not be as natural and intuitive as they are designed to be.
Anarchy in Japan’s film industry: How punk rescued Japanese cinema
Authors: Player Mark 
Published: July 2017

Abstract
When punk impressed itself upon Japanese youth culture in the mid-to-late 1970s, it arrived at a time when the nation’s film industry was in crisis. The major studio system that had presided over film production for several decades was in serious decline, curbing opportunities for the next generation of filmmaking talent by ceasing to take on new apprentices. Inspired by the ‘do-it-yourself’ ideology surrounding the emerging punk scene, young, aspiring filmmakers took matters into their own hands by forming small clubs to self-produce zero-budget short and feature-length films on their own terms, relying on friends, classmates, musicians and other hangers-on, and using increasingly accessible Super 8 and 16mm filmmaking equipment. In doing so, punk-inspired jishu seisaku eiga (‘autonomously produced cinema’) became an exciting nonprofessional alternative to the stagnating professional studio system, with many of its amateur participants going on to become influential professional figures within the Japanese film industry of today. This article seeks to provide an exploration of punk’s overlooked emergence in Japan, its impact on (and synthesis with) jishu film production, it being a catalyst for important aesthetic and generic schisms such as ‘cyberpunk’, and how it ultimately mobilized Japanese cinema to rejuvenate itself.
Um saber montado: Georges Didi-Huberman a montar imagem e tempo
Authors: Queiroz Campos Daniela 
Published: July 2017

O presente artigo aborda a perspectiva da montagem na obra do historiador da arte e filósofo francês Georges Didi-Huberman. Sua sólida e grande obra insiste na imagem como verídico problema e na necessidade do pesquisador em saber olhá-la, para tal acredita que devemos colocá-las em relação. Colocá-las uma ao lado das outras, pois imagens não falam de forma isolada. Esse conhecimento por montagem insistido por Didi-Huberman têm sólidas bases teóricas. Neste breve artigo buscou-se problematizar a perspectivas teórica da montagem didi-hubermaniana através dos escritos e das teorias acerca da montagem de três grandes intelectuais: Walter Benjamin, Aby Warburg e Serguei Eisenstein. Para tais, a montagem e a desmontagem são de singular relevância na concepção de imagem e tempo.
An evolving political landscape: Political reform, boundary changes and the 2014 local elections
Authors: Kavanagh Adrian P. 
Published: July 2017

Abstract
This paper reviews the May 2014 local election contests in the Republic of Ireland, while also offering a brief overview of the contests in Northern Ireland. These local elections took place in the context of radical changes to local government structures on both sides of the border – changes which would frame the types of choices open to voters at the May 2014 contests. The new – and generally larger – constituency areas opened up opportunity spaces for new candidates (including new female candidates) to participate in local electoral politics, although these opportunities, in turn, were very much framed by geography. The overall reduction in local representation levels in rural areas in the Republic of Ireland meant that incumbency factors acted as significant brakes on the entry of new candidates in these areas. The radically changing political landscape associated with the era of austerity politics saw a major swing against the government parties in the Republic of Ireland, with notable gains made by Sinn Féin and a number of other anti-establishment parties and groupings. These changes have brought about the formation of new alliances to control different local authorities, which, in turn, have posed an increasing set of challenges in terms of the governance of such councils, as evident in a number of conflicts over council budgets in the winter of 2014.

Authors: Carmona Tapia José , Molino Salas Alexis , Rossi Julio D. 
Published: July 2017

Abstract
In this paper, we study the existence of viscosity solutions to the Gelfand problem
for the 1-homogeneous p-Laplacian in a bounded domain

{\Omega\subset\mathbb{R}^{N}}

, that is, we deal with

-\frac{1}{p-1}\lvert\nabla u\rvert^{2-p}\operatorname{div}(\lvert\nabla u%
\rvert^{p-2}\nabla u)=\lambda e^{u}

in Ω
with

{u=0}

on

{\partial\Omega}

. For this problem we show that, for

{p\in[2,\infty]}

,
there exists a positive critical value

{\lambda^{*}=\lambda^{*}(\Omega,N,p)}

such that the following holds:

•
If

{\lambda<\lambda^{*}}

, the problem admits a minimal positive solution

{w_{\lambda}}

.

•
If

{\lambda>\lambda^{*}}

, the problem admits no solution.

Moreover, the branch of minimal solutions

{\{w_{\lambda}\}}

is increasing with λ.
In addition, using degree theory, for fixed p we show that there exists an unbounded continuum of solutions that emanates from the trivial solution

{u=0}

with

{\lambda=0}

, and for a small fixed λ we also obtain a continuum of solutions with

A nonlinear model for the characterization and optimization of athletic training and performance
Authors: Turner James D. , Mazzoleni Michael J. , Little Jared A. , Sequeira Dane , Mann Brian P. 
Published: July 2017

Summary
Study aim: Mathematical models of the relationship between training and performance facilitate the design of training protocols to achieve performance goals. However, current linear models do not account for nonlinear physiological effects such as saturation and over-training. This severely limits their practical applicability, especially for optimizing training strategies. This study describes, analyzes, and applies a new nonlinear model to account for these physiological effects. Material and methods: This study considers the equilibria and step response of the nonlinear differential equation model to show its characteristics and trends, optimizes training protocols using genetic algorithms to maximize performance by applying the model under various realistic constraints, and presents a case study fitting the model to human performance data. Results: The nonlinear model captures the saturation and over-training effects; produces realistic training protocols with training progression, a high-intensity phase, and a taper; and closely fits the experimental performance data. Fitting the model parameters to subsets of the data identifies which parameters have the largest variability but reveals that the performance predictions are relatively consistent. Conclusions: These findings provide a new mathematical foundation for modeling and optimizing athletic training routines subject to an individual’s personal physiology, constraints, and performance goals.

Energetic BEM for the numerical analysis of 2D Dirichlet damped wave propagation exterior problems
Authors: Aimi A. , Diligenti M. , Guardasoni C. 
Published: July 2017

Abstract
Time-dependent problems modeled by hyperbolic partial differential equations can be reformulated in terms of boundary integral equations and solved via the boundary element method. In this context, the analysis of damping phenomena that occur in many physics and engineering problems is a novelty. Starting from a recently developed energetic space-time weak formulation for 1D damped wave propagation problems rewritten in terms of boundary integral equations, we develop here an extension of the so-called energetic boundary element method for the 2D case. Several numerical benchmarks, whose numerical results confirm accuracy and stability of the proposed technique, already proved for the numerical treatment of undamped wave propagation problems in several dimensions and for the 1D damped case, are illustrated and discussed.
Large Eddy Simulation of gravity currents with a high order DG method
Authors: Bassi Caterina , Abbà Antonella , Bonaventura Luca , Valdettaro Lorenzo 
Published: July 2017

Abstract
This work deals with Direct Numerical Simulations (DNS) and Large Eddy Simulations (LES) of a turbulent gravity current in a gas, performed by means of a Discontinuous Galerkin (DG) Finite Elements method employing, in the LES case, LES-DG turbulence models previously introduced by the authors. Numerical simulations of non-Boussinesq lock-exchange benchmark problems show that, in the DNS case, the proposed method allows to correctly reproduce relevant features of variable density gas ows with gravity. Moreover, the LES results highlight, also in this context, the excessively high dissipation of the Smagorinsky model with respect to the Germano dynamic procedure.

Authors: Robier Christoph , Körber Carolin , Quehenberger Franz , Neubauer Manfred , Wölfler Albert 
Published: July 2017

Abstract

Background:
Red blood cells (RBC) resembling the silhouette of a fish are rarely observed in peripheral blood (PB) smears. In this study, we determined the frequency of occurrence of fish-shaped RBC in different haematologic diseases.

Methods:
We examined PB smears of patients with iron deficiency anaemia (IDA) (n=23), β-thalassaemia minor (BTM) (n=30), sickle cell disease (SCD) (n=7), autoimmune haemolytic anaemia (AIHA) (n=13), microangiopathic haemolytic anaemia (MAHA) (n=11), hereditary sphaerocytosis (HS) (n=4), hereditary elliptocytosis (HE) (n=3), vitamin B12 and folate deficiency (n=15), anaemia in liver disease (LD) (n=17), myelodysplastic syndrome (MDS) (n=15), acute myeloid leukaemia (AML) (n=29), chronic myeloid leukaemia (CML) (n=18), primary myelofibrosis (PMF) (n=12), chronic myelo-monocytic leukaemia (CMML) (n=15) and 21 healthy controls by light microscopy for the occurrence of fish-shaped erythrocytes. The fish-shaped RBC were counted as cells per 20 high-power fields (HPF) at 1000-fold magnification, and slides containing ≥1 fish-shaped RBC/20 HPF were regarded as positive.

Results:
Fish-shaped RBC were significantly found in HE, iron deficiency, vitamin B12/folate deficiency, LD and PMF. The highest numbers of fish-shaped RBC were seen in HE and vitamin B12/folate deficiency. In patients with BTM, MDS, AML and CMML, this RBC anomaly was only occasionally observed. Furthermore, a statistically significant negative correlation of haemoglobin with the occurrence of fish-shaped RBC was apparent (p<0.014).

Conclusions:
Our data show that the occurrence of fish-shaped RBC is suggestive of a pathologic condition, especially IDA, HE, vitamin B12 or folate deficiency, primary mylofibrosis or LD, and is significantly associated with severity of anaemia.

Abstract

Background
Bullying is a worldwide problem with varying consequences. Victims of school bullying may be targeted for many reasons including their appearance. They may also fear school and have difficulties in concentration.

Objective
This study aimed to determine the prevalence of bullying amongst adolescents in Kano, Northern Nigeria, the contribution of physical features and the perceived effect of bullying on their academic performance and school attendance.

Subjects and methods
Eight hundred and thirty-five students aged between 12 years and 17 years from eight randomly selected secondary schools in Kano, Nigeria took part in this study. Data collection was by self-administered questionnaires and analysis was by SPSS version 17.

Results
The pupils’ mean age and standard deviation was 14.79 + 1.53 years. There were more male and private school pupils with 55.1% and 62%, respectively. About 43% of respondents reported being victims of bullying while about 32% had bullied someone else. There was more bullying in public schools than in private schools (p-value = 0.003). However, there was no significant gender difference (p > 0.05). More bullied pupils hated being in or outside the classroom (p < 0.05). Similarly, significantly higher number of bullied pupils played truant than non-bullied (p < 0.001). One-fifth of the victims of bullying felt it had consequences on their academic performance. Bullies frequently targeted general physical and dento-facial appearance.

Conclusion
The prevalence of bullying was high among the sampled population especially within public schools. This also had a significant negative effect on the students’ academic performance.
On the Mittag–Leffler Stability of Impulsive Fractional Solow-Type Models
Authors: Stamova Ivanka M. , Stamov Gani Tr. 
Published: July 2017

AbstractIn this article, we introduce fractional-order Solow-type models as a new tool for modeling and analysis in mathematical finance. Sufficient conditions for the Mittag–Leffler stability of their states are derived. The main advantages of the proposed approach are using of fractional-order derivatives, whose nonlocal property makes the fractional calculus a suitable tool for modeling actual financial systems as well as using of impulsive perturbations which give an opportunity to control the dynamic behavior of the model. The modeling approach proposed in this article can be applied to investigate macroeconomic systems.
Analysis of the Use of Background Distribution for Naive Bayes Classifiers
Authors: Andrade Daniel , Tamura Akihiro , Tsuchida Masaaki 
Published: July 2017

AbstractThe naive Bayes classifier is a popular classifier, as it is easy to train, requires no cross-validation for parameter tuning, and can be easily extended due to its generative model. Moreover, recently it was shown that the word probabilities (background distribution) estimated from large unlabeled corpora could be used to improve the parameter estimation of naive Bayes. However, previous methods do not explicitly allow to control how much the background distribution can influence the estimation of naive Bayes parameters. In contrast, we investigate an extension of the graphical model of naive Bayes such that a word is either generated from a background distribution or from a class-specific word distribution. We theoretically analyze this model and show the connection to Jelinek-Mercer smoothing. Experiments using four standard text classification data sets show that the proposed method can statistically significantly outperform previous methods that use the same background distribution.
Novel Relevance Feedback Approach for Color Trademark Recognition Using Optimization and Learning Strategy
Authors: Pinjarkar Latika , Sharma Manisha , Selot Smita 
Published: July 2017

Abstract
The trademark registration process, apparent in all organizations nowadays, deals with recognition and retrieval of similar trademark images from trademark databases. Trademark retrieval is an imperative application area of content-based image retrieval. The main challenges in designing and developing this application area are reducing the semantic gap, obtaining higher accuracy, reducing computation complexity, and subsequently the execution time. The proposed work focuses on these challenges. This paper proposes the relevance feedback system embedded with optimization and unsupervised learning technique as the preprocessing stage, for trademark recognition. The search space is reduced by using particle swam optimization, for optimization of database feature set, which is further followed by clustering using self-organizing map. The relevance feedback technique is implemented over this preprocessed feature set. Experimentation is done using the FlickrLogos-32 PLUS dataset. To introduce variations between the training and query images, transformations are applied to each of the query image, viz. rotation, scaling, and translation of the image. The same query image is tested for various combinations of transformations. The proposed technique is invariant to various transformations, with significant performance as depicted in the results.
Volatility Modeling with Leverage Effect under Laplace Errors
Authors: Jiang Zhengjun , Xia Weixuan 
Published: July 2017

Abstract
This paper discusses four GARCH-type models (A-GARCH, NA-GARCH, GJR-GARCH, and E-GARCH) in representing volatility of financial returns with leverage effect. In these models, errors are assumed to follow a Laplace distribution in order to deal with the typical leptokurtic feature of financial returns. The properties of these models are analyzed theoretically in terms of unconditional variance, kurtosis, autocorrelation function and news impact, and are further examined in the applications to real financial time series. Comparison is made with other choices of error distributions such as normal, Student-5, and Student-7 distributions, respectively. We also conduct residual analyses to justify the choice of error distributions and find that Laplace-E-GARCH model still performs very well. Our main purpose is to study and compare the proposed models’ relative adequacies and underlying limitations.
