When the Assignment Map Is Completely Positive

Finding the general set of system-environment states {ρSE} for which the reduced dynamics of the system is completely positive (CP) is the subject of some recent works. An advance in this context appeared in [7], where the problem was solved for the case of CP assignment map. Here, we restate this result using the framework introduced in [8]. This, we think, clarifies the mentioned result better and so leads to a generalization of it, straightforwardly.
A Machine Learning View on Momentum and Reversal Trading

Momentum and reversal effects are important phenomena in stock markets. In academia, relevant studies have been conducted for years. Researchers have attempted to analyze these phenomena using statistical methods and to give some plausible explanations. However, those explanations are sometimes unconvincing. Furthermore, it is very difficult to transfer the findings of these studies to real-world investment trading strategies due to the lack of predictive ability. This paper represents the first attempt to adopt machine learning techniques for investigating the momentum and reversal effects occurring in any stock market. In the study, various machine learning techniques, including the Decision Tree (DT), Support Vector Machine (SVM), Multilayer Perceptron Neural Network (MLP), and Long Short-Term Memory Neural Network (LSTM) were explored and compared carefully. Several models built on these machine learning approaches were used to predict the momentum or reversal effect on the stock market of mainland China, thus allowing investors to build corresponding trading strategies. The experimental results demonstrated that these machine learning approaches, especially the SVM, are beneficial for capturing the relevant momentum and reversal effects, and possibly building profitable trading strategies. Moreover, we propose the corresponding trading strategies in terms of market states to acquire the best investment returns.
Towards the Verbal Decision Analysis Paradigm for Implementable Prioritization of Software Requirements

The activity of prioritizing software requirements should be done as efficiently as possible. Selecting the most stable requirements for the most important customers of a development company can be a positive factor considering that available resources do not always encompass the implementation of all requirements. There are many quantitative methods for prioritization of software releases in the field of search-based software engineering (SBSE). However, we show that it is possible to use qualitative verbal decision analysis (VDA) methods to solve this type of problem. Moreover, we will use the ZAPROS III-i method to prioritize requirements considering the opinion of the decision-maker, who will participate in this process. Results obtained using VDA structured methods were found to be quite satisfactory when compared to methods using SBSE. A comparison of results between quantitative and qualitative methods will be made and discussed later. The results were reviewed and corroborated with the use of performance metrics.
Bidirectional Grid Long Short-Term Memory (BiGridLSTM): A Method to Address Context-Sensitivity and Vanishing Gradient

The Recurrent Neural Network (RNN) utilizes dynamically changing time information through time cycles, so it is very suitable for tasks with time sequence characteristics. However, with the increase of the number of layers, the vanishing gradient occurs in the RNN. The Grid Long Short-Term Memory (GridLSTM) recurrent neural network can alleviate this problem in two dimensions by taking advantage of the two dimensions calculated in time and depth. In addition, the time sequence task is related to the information of the current moment before and after. In this paper, we propose a method that takes into account context-sensitivity and gradient problems, namely the Bidirectional Grid Long Short-Term Memory (BiGridLSTM) recurrent neural network. This model not only takes advantage of the grid architecture, but it also captures information around the current moment. A large number of experiments on the dataset LibriSpeech show that BiGridLSTM is superior to other deep LSTM models and unidirectional LSTM models, and, when compared with GridLSTM, it gets about 26 percent gain improvement.
Patients' and GPs' expectations regarding healthcare-seeking behaviour: a Norwegian comparative study

Background GPs are Norwegian patients' first contact point with the healthcare system for most medical problems. However, little is known regarding GPs' expectations towards their patients' healthcare-seeking behaviour, or whether doctors and patients have coinciding expectations of what GPs can do for their patients. Aim To investigate patients' and GPs’ expectations regarding patients’ healthcare-seeking behaviour in primary care, and to make comparisons between the two. Design & setting Norwegian data from the Quality and Costs of Primary Care in Europe (QUALICOPC) questionnaire study, with information from GPs and their patients. Method Binary logistic regression was used to investigate associations between expectations, sex and age of GPs and patients, list size, and geographical location of practice. Results are presented as odds ratios (ORs) with 95% confidence intervals (CIs). Expectation differences between GPs and patients were analysed using generalised estimating equations (GEEs). Due to multiple testing, Bonferroni correction was used to define significance level at P≤0.002. Results In total, 198 GPs (39.1% female) and 1529 patients (61.9% female) responded. No associations with sex or age were found for the GPs' expectations regarding patients' healthcare-seeking behaviour. Among patients, fewer males than females expected that most people would see their GP for sprained ankle (OR 0.7, 95% CI = 0.5 to 0.9), finger cut (OR 0.6, 95% CI = 0.4 to 0.7), smoking cessation (OR 0.6, 95% CI = 0.5 to 0.8), or anxiety (OR 0.4, 95% CI = 0.3 to 0.6). Older patients (aged >65 years) found it more important than younger patients to see a doctor in the presence of medical symptoms. GPs had higher expectations than their patients that people in general would see them for deteriorated vision (OR 4.2, 95% CI = 2.5 to 6.9), sexual problems (OR 1.8, 95% CI =1.3 to 2.6), and anxiety (OR 3.0, 95% CI =1.5 to 6.0). Conclusion For several common health problems, males are less likely than females to believe that people will see their GP. GPs may overestimate to what degree their patients will see them for a number of common medical problems.
Quelles sont les origines du ministère de l’Identité nationale et de l’Immigration ?

Annoncee a la television le 8 mars 2007 par le candidat Nicolas Sarkozy, la creation du ministere de l’Immigration, de l’Integration, de l’Identite nationale et du Codeveloppement a d’abord ete en France une promesse electorale, un sujet de campagne et aurait pu connaitre le sort d’autres idees de ce genre : etre oubliee ou reformulee une fois le candidat arrive au pouvoir. On pouvait alors se demander s’il ne s’agissait que d’un simple gadget de campagne, destine a ratisser les voix de l’ext.

Las subfamilias Pimelodinae, Heptapterinae y Pseudopimelodinae parecen formar un grupo natural
Effect of the Auricular Acupressure Therapy on Dysmenorrhea of Puberty Girls.

PURPOSE The purpose of this study was to identify the effect of auricular acupressure therapy on dysmenorrhea of puberty girls. METHODS This study was a pretest-posttest design with a nonequivalent control group. The subjects of this study were 61 girls who were middle and high school students in Seoul and the experiencing dysmenorrhea; 31 for the experimental group and 30 for the control group. The obtained data were analyzed by SPSS/WIN 12.0 program. RESULTS The experimental group which applied the auricular acupressure therapy scored lower for low abdominal pain (F=136.13, p=.000), low back pain (F=62.79, p=.000). autonomic nervous system reactions (F=102.31, p=.000) and negative emotions on the menstruation (F=102.31, p=.000) compared to the control group. There were significant interaction effects of auricular acupressure on low abdominal pain, low back pain, autonomic nervous system reactions, and negative emotions on the menstruation between time and group. CONCLUSION We observed that auricular acupressure therapy is effective for reliving pain and the symptom of dysmenorrhea. Based on these result, auricular acupuncture is useful by individual nursing intervention and improves the quality of life for dysmenorrhea of puberty girls.
Can a Presepsin (Scd14-St) Obtained from Tracheal Aspirate Be a Biomarker for Early- Onset Neonatal Sepsis

In absence of clear clinical signs and clear definition, neonatal sepsis is still one of the major cause of morbidity and mortality. Most researchs in past time was directional on finding new biomarkers with greater sensitivity and specificity in detection of neonatal sepsis. The aim of our study was to investigate if presepsin obtained from tracheal asprate in intubated newborns, can be a novel biomarker of systemic bacterial infection. Our ‘’case control’’ study included 60 newborns, 11 with suspected neonatal sepsis. Tracheal aspirate for examination was taken in the usual toilets, in aseptic conditions, by lavage with 2 ml of 0.9% NaCl in Mucus suction set. In the same day were mesured presepsin (blood), CRP, PCT, leukocytes and neutrophyls, as well as blood culture. Our research showed higher levels for PCT and presepsin (blood) in septic newborns, as well as in newborns with clinical signs of SIRS. Presepsin obtained from a tracheal aspirate had high score for septic newborns. As the coefficients of simple linear correlation showed, there was quantitative agreement between presepsin (blood) with presepsin (tracheal aspirate)- increase in the value of one leads to an increase in other. In conjunction with an already validated markers of infection, presepsin obtained from tracheal aspirate cam be turned on in diagnostic procedures.
Factors Associated with Common Sexual Concerns in Women: New Findings from the Canadian Contraception Study

The 2002 Canadian Contraception Study a national survey of 1582 women aged 15-44 reported that 55% of respondents had experienced one or more of three sexual concerns in the past year including lower sexual desire (40%) infrequent coital orgasm (23%) and pain during intercourse (14%). The present secondary analysis of these data explores the association of these three sexual concerns with other factors measured in the study including age body weight number of children education level marital status sexual concerns experienced by a partner and method of contraception. Each of these factors was shown to be associated with one or more of the three sexual health concerns. This study is the first to use a large national sample of Canadian women to identify the correlates of female sexual function concerns. (authors)
A SIFT-based robust watermarking scheme in DWT-SVD domain using majority voting mechanism

Digital watermarking is an efficient technique for copyright protection in the current digital and network era. In this paper, a novel robust watermarking scheme is proposed based on singular value decomposition (SVD), Arnold scrambling (AS), scale invariant feature transform (SIFT) and majority voting mechanism (MVM). The watermark is embedded into each image block for three times in a novel way to enhance the robustness of the proposed watermarking scheme, while Arnold scrambling is utilized to improve the security of the proposed method. During the extraction procedure, SIFT feature points are used to detect and correct possibly geometrical attacks, and majority voting mechanism is performed to enhance the accuracy of the extracted watermark. Our analyses and experimental results demonstrate that the proposed watermarking scheme is not only robust to a wide range of common signal processing attacks (such as noise, compression and filtering attacks), but also has favorable resistance to geometrical attacks.
Stakeholder management in value-based software development: systematic review

In the value-based software (VBS) development, an innovative idea is realised in order to gain an economic leverage. The VBS systems deal with financial streams and this thing make them different from the conventional systems. The success of a VBS system is associated with a valuable set of requirements. The valuable requirements can only be gathered from success critical stakeholders. To select a set of success critical stakeholders, different stakeholders identification and quantification (SIQ) approaches are presented by the researchers. The current approaches cannot be adopted as a standard as different methods and processes are adopted in different approaches. In this study, the aim is to find out the reported evidence based attributes or characteristics of the stakeholders and their usage context in terms of their application in different domains, stakeholders' quantification metrics, the reported stakeholder types and the reported issues of VBS development. The standard systematic literature review guidelines are used as given by Barbara Kitchenham. The literature evidence shows that there is a need to explore all the possible stakeholders' attributes. The stakeholders' metrics can be derived by using the stakeholders' attributes and a new SIQ framework can be proposed for the VBS systems.
Outcome of in-hospital resuscitation in a tertiary level teaching hospital in Nepal

Teaching Language Variety

The Multiliteracies movement has stressed the importance of students learning to negotiate such differences as among ‘regional, ethnic, or class-based dialects’ and even ‘the code-switching often to be found within a text among different languages, dialects, or registers’ (New London Group 1996). The position that language learners should become familiar with such a range of varieties is not entirely new, but its bases and implications have rarely been explored at length, and even the recent book length treatment of Multiliteracies (Cope & Kalantzis 2000) says little more about the matter. The present paper reviews literature relevant to this issue to evaluate the basis for this proposal and to explore its potential impact on language teaching in the twenty-first century. In particular it will consider: • to what extent and for what reasons it is important for language learners to become familiar with different dialects and, in some situations, even distinct languages; • how the teaching of language variety can be approached in practice; and • how this issue relates to issues in the roles of language teachers, native versus non-native teachers, and computer assisted language learning.
Changes in Intrinsic Motivation and Physical Activity among Overweight Women in a 12-Week Dragon Boat Exercise Intervention Study

Physical and psychosocial health risks are associated with both excess body weight and a sedentary lifestyle (National Institutes of Health [NIH], 1998). However, few researchers have focused on behavioral and motivational processes associated with exercise adoption and maintenance among overweight women. This study examined the efficacy of a team-based physical activity intervention on motivation and activity from a self-determination theory perspective. Overweight, inactive women (N=66) were randomly assigned to either a 12-week dragon boat program or a control condition. Participation in the dragon boat exercise was associated with increased intrinsic motivation and physical activity. Based on these data, the researchers suggest that this novel, team-based exercise intervention may improve motivation and activity levels in this at-risk population.
Digital techniques for ultra-high data rate optical fibre transmission

The exponential growth of the demand for higher data rates is pushing scientists to find ways to improve the internet infrastructure, which crucially relies on optical fibres. The main obstacle to increasing transmission rates of optical fibre systems is presented by the fibre Kerr nonlinear effect, which impairs signal transmission as the transmitted power is increased. Fortunately, optical coherent detection, in combination with digital signal processing techniques, have enabled more sophisticated digital receivers, tailored to the optical fibre channel. This thesis describes a comprehensive study on the performance of two digital receiver-side techniques: digital back-propagation (DBP) and maximum likelihood sequence detection (MLSD). DBP is the most widespread digital technique to mitigate fibre nonlinearity at the receiver. The performance of DBP, is assessed for long-haul, wide-bandwidth systems, highlighting theoretical gains and practical limitations. Analytical models to predict DBP performance are discussed and compared to numerical results. The impact of polarisation-mode dispersion on the capability of DBP to remove nonlinear impairments is investigated. The principles of detection theory are discussed in the context of the optical fibre nonlinear channel. Following such principles, MLSD strategies are studied and their performance analysed for unrepeatered systems. A close to optimum receiver scheme, using the Viterbi algorithm, is proposed and investigated for the first time in a singlespan fibre system. Finally, information-theoretic tools are used to predict achievable information rates of both receiver schemes, when employed in combination with forward error correction codes. In particular, pragmatic coded modulation schemes were examined to assess the potential of off-the-shelf channel codes. Both receiving strategies analysed were demonstrated to significantly outperform conventional receivers optimised for the additive white Gaussian noise channel. The results of this thesis provide a useful insight on the properties of the optical fibre channel and on the design of receivers aiming to maximise information rates through it.
The Gender Wage Gap in France: the Role of Non-Cognitive Characteristics

(english) Differences between men and women in non-cognitive skills could be the reason why the gender gap closing didn’t improve since the middle of the nineties. To investigate this issue in the case of France we used the "Generation 1998 a 10 ans" database conducted by the Cereq. This survey provides information on gender preferences differences in terms of career versus family, risk attitudes or the vision individuals have of their professional futures. As these non-cognitive factors are likely to influence wages but also occupational choices, the decomposition of wage differentials proposed by Brown, Moon and Zoloth (1980) is implemented. This makes it possible to consider this indirect mechanism by which non-cognitive variables can determine wages, but also the potentially discriminatory nature of occupational segregation. We find that differences in non-cognitive skills matter, 6.3% of the total gender wage gap, that is almost twice as experience, but a large part, 60% of the gap, remains unexplained by the characteristics considered in this work. _________________________________ (francais) La reduction des ecarts de salaires entre les hommes et les femmes est depuis maintenant deux decennies au point mort. Le fait que les unes et les autres se distinguent en matiere de caracteristiques non cognitives constitue une des raisons qui pourrait expliquer qu’il en soit ainsi. Dans ce travail, a partir de l’enquete Generation 1998 a 10 ans realisee par le Cereq, le role que les preferences en termes de carriere versus famille, l’attitude face au risque ou le rapport a son avenir professionnel peuvent avoir sur les ecarts de salaires est examine. Comme ces facteurs non cognitifs sont susceptibles d’influencer les salaires mais aussi les choix professionnels, la decomposition des ecarts de salaires proposee par Brown, Moon et Zoloth (1980) est mise en oeuvre. Celle-ci permet de tenir compte de ce mecanisme indirect par lequel les variables non cognitives peuvent determiner les salaires, mais aussi du caractere potentiellement discriminatoire de la segregation occupationnelle. Si les differences de caracteristiques non cognitives comptent, 6,3 % de l’ecart de salaires total, soit pres de deux fois plus que l’experience, 60 % restent inexpliques par les caracteristiques retenues.
