Chun-Na Li, Zeng-Rong Zheng, Ming-Zeng Liu, Yuan-Hai Shao, Wei-Jie Chen
In this paper, we propose a novel absolute value inequalities discriminant analysis (AVIDA) criterion for supervised dimensionality reduction. Compared with the conventional linear discriminant analysis (LDA), the main characteristics of our AVIDA are robustness and sparseness. By reformulating the generalized eigenvalue problem in LDA to a related SVM-type "concave-convex" problem based on absolute value inequalities loss, our AVIDA is not only more robust to outliers and noises, but also avoids the SSS problem...

2-D principal component analysis (2DPCA), which employs squared F-norm as the distance metric, has been widely used in dimensionality reduction for data representation and classification. It, however, is commonly known that squared F-norm is very sensitivity to outliers. To handle this problem, we present a novel formulation for 2DPCA, namely Angle-2DPCA. It employs F-norm as the distance metric and takes into consideration the relationship between reconstruction error and variance in the objective function...

Multi-label problems arise in various domains including automatic multimedia data categorization, and have generated significant interest in computer vision and machine learning community. However, existing methods do not adequately address two key challenges: exploiting correlations between labels and making up for the lack of labeled data or even missing labeled data. In this paper, we proposed to use a semi-supervised singular value decomposition to handle these two challenges. The proposed model takes advantage of the nuclear norm regularization on the singular value decomposition to effectively capture the label correlations...

In some areas of rural Africa, long-standing cultural traditions and beliefs may discourage parents from verbally engaging with their young children. This study assessed the effectiveness of a parenting program designed to encourage verbal engagement between caregivers and infants in Wolof-speaking villages in rural Senegal. Caregivers (n = 443) and their 4- to 31-month-old children were observed at baseline in 2013 and 1 year later at follow-up. Results showed that caregivers in program villages nearly doubled the amount of child-directed speech during a play session compared to baseline, whereas caregivers in matched comparison villages showed no change...

OBJECTIVE: Understanding a child's ability to decode emotion expressions is important to allow early interventions for potential difficulties in social and emotional functioning. This study applied the Rasch model to investigate the psychometric properties of the NEPSY-II Affect Recognition subtest, a U.S. normed measure for 3-16 year olds which assesses the ability to recognize facial expressions of emotion. METHOD: Data were collected from 1222 children attending preschools in Singapore...

AIM: To improve the efficacy of intercalating dyes to distinguishing between infectious and inactivated hepatitis A virus (HAV) in food. METHODS AND RESULTS: Different intercalating dyes were evaluated for the discrimination between infectious and thermally-inactivated HAV suspensions combining with the RT-qPCR proposed in the ISO 15216. Among them, PMAxx was the best dye in removing the RT-qPCR signal from inactivated HAV. Applied to lettuce and spinach, PMAxx-Triton pretreatment resulted in complete removal of the RT-qPCR signal from inactivated HAV...

Global warming has been commonly accepted to facilitate species' range shifts across latitudes. Cross-latitudinal transplantations support this; many tree species can well adapt to new geographical areas. However, these studies fail to capture species' adaptations to new light environment because the experiments were not designed to explicitly separate species' responses to light and temperature. Here we tested reaction norms of tree seedlings in reciprocal transplantations 1,000 km apart from each other at two latitudes (60°N and 69°N)...

BACKGROUND: Cranial and cervical muscle activity (electromyogram, EMG) contaminates the surface electroencephalogram (EEG) from frequencies below 20 through to frequencies above 100Hz. It is not possible to have a reliable measure of cognitive tasks expressed in EEG at gamma-band frequencies until the muscle contamination is removed. NEW METHOD: In the present work, we introduce a new approach of using a minimum-norm based beamforming technique (sLORETA) to reduce tonic muscle contamination at sensor level...

INTRODUCTION: Firearm violence injures or kills 100,000 Americans each year. This paper applies the Host-Agent-Vector-Environment model to this issue. Research on firearm violence tends to focus on two elements-the host (i.e., victims of firearm violence) and the environment (i.e., gun policies)-but little attention has been paid to the agent (the gun and ammunition) or the vector (firearm manufacturers, dealers, and the industry lobby). METHODS: Using Bureau of Alcohol, Tobacco, Firearms and Explosives data, trends in firearm manufacturing were investigated from 1990 to 2015...

OBJECTIVES: Breastfeeding confers important health benefits to both infants and their mothers, but rates are low in the United Kingdom and other developed countries despite widespread promotion. This study examined the relationships between personal and vicarious experience of infant feeding, self-efficacy, the theory of planned behaviour variables of attitudes and subjective norm, and the likelihood of breastfeeding at 6-8 weeks post-natally. DESIGN: A prospective questionnaire study of both first-time mothers (n = 77) and experienced breastfeeders (n = 72) recruited at an antenatal clinic in South East England...

Humans make moral judgments every day, and research demonstrates that these evaluations are based on a host of related event features (e.g., harm, legality). In order to acquire systematic data on how moral judgments are made, our assessments need to be expanded to include real-life, ecologically valid stimuli that take into account the numerous event features that are known to influence moral judgment. To facilitate this, Knutson et al. (in Social Cognitive and Affective Neuroscience, 5(4), 378-384, 2010) developed vignettes based on real-life episodic memories rated concurrently on key moral features; however, the method is time intensive (~1...

The present investigation sought to extend extant research on subjective sleep complaints by examining their relation to perceived sleep norms. Results from two studies showed that individuals' distress and illness behavior in response to symptoms of fatigue and non-restorative sleep was influenced by their perceptions of peer norms for those symptoms. Individuals who believed they experienced a greater degree of fatigue and non-restorative sleep than their peers reported more distress arising from those symptoms, and were also more likely to seek social support and medical treatment for them...

Being a member of a peer group involves making decisions about whom to include in or exclude from the group. Sometimes these decisions are related to whether members of the group support or challenge the norms of the group. To examine how young children weigh concerns for group norms and group membership in both moral and social-conventional norm contexts, children (3- to 6-year-olds; N=73) were asked to decide between including an ingroup member who challenged the group's norm or an outgroup member who supported the norm...

REVIEW
Norm R C Campbell, Emma J Train
There are sporadic cases of fatalities from acutely eating salt. Yet, on social media, there are "challenges to" and examples of children and some adults acutely eating salt, and recently a charity advocated eating small amounts of salt to empathize with Syrian refugees. We performed a systematic review of fatalities from ingesting salt to assess if relatively moderate doses of salt could be fatal. In 27 reports, there were 35 fatalities documented (19 in adults and 16 in children). The lethal dose was estimated to be less than 10 g of sodium (<5 teaspoons of salt) in two children, and less than 25 g sodium in four adults (<4 tablespoons of salt)...

Birgit Kvernflaten
To achieve Millennium Development Goal 5 on maternal health, many countries have focused on marginalized women who lack access to care. Promoting facility-based deliveries to ensure skilled birth attendance and emergency obstetric care has become a main measure for preventing maternal deaths, so women who opt for home births are often considered 'marginal' and in need of targeted intervention. Drawing upon ethnographic data from Nicaragua, this paper critically examines the concept of marginality in the context of official efforts to increase institutional delivery amongst the rural poor, and discusses lack of access to health services among women living in peripheral areas as a process of marginalization...

The article proposes a critical reflection on issues that appeal to the conscience clause as part of end of life care can produce and what can guarantee freedom of conscience, self-determination of those involved and respect for the dignity of the sick person. After a philosophical and normative analysis, the article is organized on the basis of two important documents for discussion: a position paper of Società Italiana di Anestesia Analgesia Rianimazione e Terapia Intensiva (SIAARTI) signed by several scientific societies "Grandi insufficienze d'organo end stage: cure intensive o cure palliative?" and the Design of Law currently being debated "Norme in materia di consenso informato e di disposizioni anticipate di trattamento"...

It is generally believed that concepts can be characterized by their properties (or features). When investigating concepts encoded in language, researchers often ask subjects to produce lists of properties that describe them (i.e., the Property Listing Task, PLT). These lists are accumulated to produce Conceptual Property Norms (CPNs). CPNs contain frequency distributions of properties for individual concepts. It is widely believed that these distributions represent the underlying semantic structure of those concepts...

While the effectiveness of substance use prevention programs such as the Strengthening Families Program 10-14 (SFP) has been demonstrated in the USA, European SFP adaptations have not replicated these sizable effects. Following the rationale of the risk moderation hypothesis positing that elevated risk groups may benefit more from a preventive intervention than lower-risk groups, we reanalyzed evaluation data from a randomized controlled trial testing the adapted German version of SFP (SFP-D). We hypothesized a differential impact of risk status on intervention results...
