A Nash Equilibrium Need Not Exist in the Locational Marginal Pricing Mechanism

Locational marginal pricing (LMP) is a widely employed method for pricing electricity in the wholesale electricity market. Although it is well known that the LMP mechanism is vulnerable to market manipulation, there is little literature providing a systematic analysis of this phenomenon. In the first part of this paper, we investigate the economic dispatch outcomes of the LMP mechanism with strategic agents. We show via counterexamples, that contrary to popular belief, a Nash equilibrium may not exist. And when it exists, the price of anarchy may be arbitrarily large. We then provide two sufficient conditions under either of which an efficient Nash equilibria exists. Last, we propose a new market mechanism for electricity markets, the Power Network Second Price (PNSP) mechanism that always induces an efficient Nash equilibrium. We briefly address the extensions on the demand side.
Extensive Comparison of Visual Features for Person Re-identification

Person re-identification is one of the most critical tasks in the field of computer vision and has widely applications for abnormal detection and object retrieval in video surveillance. In this paper, we give an extensive comparison for different kinds of visual features including hand-craft features and Convolutional Neural Networks (CNN) features. We run the experiments on three public dataset CASIA, Market1501 and CUHK03. Through A detail comparison and analysis on different features with different similarity measures, we find Colorhistogram and ScalableColor features are most robust to occlusion on CASIA, while GoogleNet and VG-GNet features have good robustness as well. For all single features, GoogleNet feature achieves the highest results on Market1501 and CUHK03. For feature fustion, GoogleNet feature with ColorStructure achieve the best result on Market1501 and GoogleNet feature wth Colorhistogram achieve the best result on CUHK03. For similarity measure, Cosine distance is evaluated to be the best one in our experiments.
A role for onomatopoeia in early language: evidence from phonological development

abstract Onomatopoeia appear in high quantities in many infants’ earliest words, yet there is minimal research in this area. Instead, findings from the wider iconicity literature are generalised to include onomatopoeia, leading to the assumption that their iconic status makes them inherently learnable, thereby prompting their early production. In this review we bring together the literature on onomatopoeia specifically and iconicity more generally to consider infants’ acquisition from three perspectives: perception, production, and interaction. We consider these findings in relation to Imai and Kita’s (2014) ‘sound symbolism bootstrapping hypothesis’ to determine whether their framework can account for onomatopoeia alongside other iconic forms.
Validating the extended character morality questionnaire

ABSTRACT The morality of observed others is a central variable for many media effects research areas, including affective disposition theory, social cognitive theory, and entertainment-education. A scale designed to measure five distinct aspects of the morality of characters is validated in a series of six studies (N = 1,204). Findings suggest that the extended character morality questionnaire (CMFQ-X) possesses adequate statistical validity as indicated through confirmatory factory analysis. In addition, the subscales show good internal consistency. Convergent and discriminant validity were assessed through the measurement of other constructs. As expected, scores on the subscales of the CMFQ-X correlated substantially with related constructs and unsubstantially with unrelated constructs. Finally, the validity of a short-form version of the scale (CMFQ-S) for use in studies in which participant fatigue may be an issue is examined.
QUALITY OF CROWDSOURCED RELEVANCE JUDGMENTS IN ASSOCIATION WITH LOGICAL REASONING ABILITY

Crowdsourcing has become a low-cost and scalable alternative to gather relevance assessments through crowdsourcing platforms. However, when gathering subjective human judgments, it can be challenging to enforce data quality due to the lack of vision about how judges make a decision. It is important to determine the attributes that could affect the effectiveness of crowsourced-judgments in an information retrieval systems evaluation. The purpose of the experiment that is discussed in this paper is to investigate if logical reasoning ability of the crowd workers is related to the quality of the relevant judgments produced through the crowdsource process. The study also evaluates the effect of cognitive characteristics on the quality of relevance judgment compared to the gold standard dataset. Through this experiment, a comparison study is done between the quality of the judgments obtained through the crowdsourcing process and the original baseline judgments generated by the hired experts by TREC. In the study, the systems performances were measured using both of these sets of relevance judgments to see its correlation. The experimentation reveals that quality of relevance judgments is highly correlated with the logical reasoning ability of individuals. The judgment difficulty level reported by the crowdsource workers and the confidence level claimed by the workers showed a significant correlation with the quality of the judgments. Unexpectedly though, self-reported knowledge about a given topic and demographics data have no correlation with the quality of judgments produced through crowdsourcing.
Responses to inpatient victimisation in mental health settings in England and Wales

Mental health inpatients are known to be at risk of criminal victimisation, but the experiences of this vulnerable victim population seldom receive mention in the victimological literature. Against this backdrop, this article explores to what extent and in what ways mental health inpatients report victimisation, and provides the first systematic analysis of what the existing evidence base tells us about the subsequent responses of mental health services and criminal justice agencies, particularly in England and Wales. Identified knowledge gaps are problematised as impediments to evaluation of both policy and practice in this context. An agenda for future research is additionally sketched out.
Why Build a CRM Capability When So Many Appear to Fail ?

The market enthusiasm generated around investment in CRM technology is in stark contrast to the naysaying by many academic and business commentators. This raises an important research question concerning the extent to which companies should continue to invest in building a CRM capability. Drawing on field interviews and a survey of senior executives, the results reveal that a superior CRM capability can create positional advantage and subsequent improved performance. Further, it is shown that to be most successful, CRM programs should focus on latent or unarticulated customer needs that underpin a proactive market orientation.
The Role of the Transcription Factor SIM2 in Prostate Cancer

Background Recent reports have suggested a possible involvement of Single-minded homolog 2 (SIM2) in human solid cancers, including prostate cancer. However, the exact role of SIM2 in cancer in general, and in prostate cancer in particular, remains largely unknown. This study was designed to elucidate the role of SIM2 in prostate cancer using a shRNA-based approach in the PC3 prostate cancer cell line. Methods Lentiviral shRNAs were used to inhibit SIM2 gene and protein levels in PC3 cells. Quantitative RT-PCR and branched DNA were performed to evaluate transcript expression. SIM2 protein expression level was measured by western blot. Profiling of gene expression spanning the whole genome, as well as polar metabolomics of several major metabolic pathways was performed to identify major pathway dysregulations. Results SIM2 gene and protein products were significantly downregulated by lenti-shRNA in PC3 cell line. This low expression of SIM2 affected gene expression profile, revealing significant changes in major signaling pathways, networks and functions. In addition, major metabolic pathways were affected. Conclusion Taken together, our results suggest an involvement of SIM2 in key traits of prostate tumor cell biology and might underlie a contribution of this transcription factor to prostate cancer onset and progression.
Random Forests toolbox with scilab and its application

Scilab is the famous open source software. Scilab has been extensively received and it has been designed a open system. So scilab is a good platform to develop some useful toolbox. Random Forests is an excellent machine learning algorithm. It is efficient to process large data and can solve unbalanced classification problems. It has been used widely. While because of some disadvantages, the current toolboxes are not popular. In this paper, we develop a toolbox of Random Forests with scilab. We test its performance and apply it to handwritten numeral recognition. The objective of this work is to promote the toolbox and facilitate more users.
“It keeps me on my toes”

This article reports on the findings of a questionnaire survey of 465 telephone interpreters in Australia, focusing on what they liked and disliked about telephone interpreting, their perceptions of challenges in telephone interpreting, and their coping strategies. Just over half of the respondents liked working as telephone interpreters. Results also show that interpreters identified many favourable and unfavourable aspects of telephone interpreting. A key finding is that interpreters perceived many comprehension-related challenges (e.g., poor sound quality, a lack of non-verbal information), communication-related challenges (e.g., overlapping speech), and other challenges in telephone interpreting (e.g., low remuneration, casual employment, work-related stress). Importantly, interpreters adopted various coping strategies, including using high-quality headphones and requesting briefing or clarification to deal with comprehension-related challenges, explaining the interpreter’s role and intervening with clients as necessary to address communication-related challenges, and reducing working hours and exercising self-care to manage work-related stress.
An International Study of the Ability and Cost-Effectiveness of Advertising Methods to Facilitate Study Participant Self-Enrolment Into a Pilot Pharmacovigilance Study During Early Pregnancy

Background Knowledge of the fetal effects of maternal medication use in pregnancy is often inadequate and current pregnancy pharmacovigilance (PV) surveillance methods have important limitations. Patient self-reporting may be able to mitigate some of these limitations, providing an adequately sized study sample can be recruited. Objective To compare the ability and cost-effectiveness of several direct-to-participant advertising methods for the recruitment of pregnant participants into a study of self-reported gestational exposures and pregnancy outcomes. Methods The Pharmacoepidemiological Research on Outcomes of Therapeutics by a European Consortium (PROTECT) pregnancy study is a non-interventional, prospective pilot study of self-reported medication use and obstetric outcomes provided by a cohort of pregnant women that was conducted in Denmark, the Netherlands, Poland, and the United Kingdom. Direct-to-participant advertisements were provided via websites, emails, leaflets, television, and social media platforms. Results Over a 70-week recruitment period direct-to-participant advertisements engaged 43,234 individuals with the study website or telephone system; 4.78% (2065/43,234) of which were successfully enrolled and provided study data. Of these 90.4% (1867/2065) were recruited via paid advertising methods, 23.0% (475/2065) of whom were in the first trimester of pregnancy. The overall costs per active recruited participant were lowest for email (€23.24) and website (€24.41) advertisements and highest for leaflet (€83.14) and television (€100.89). Website adverts were substantially superior in their ability to recruit participants during their first trimester of pregnancy (317/668, 47.5%) in comparison with other advertising methods (P<.001). However, we identified international variations in both the cost-effectiveness of the various advertisement methods used and in their ability to recruit participants in early pregnancy. Conclusions Recruitment of a pregnant cohort using direct-to-participant advertisement methods is feasible, but the total costs incurred are not insubstantial. Future research is needed to identify advertising strategies capable of recruiting large numbers of demographically representative pregnant women, preferentially in early pregnancy.
Hyperbaric oxygen therapy effects on tissue lesions in acute pancreatitis. Experimental study in rats.

OBJECTIVE To study the effects of hyperbaric oxygen therapy on tissue lesions in an experimental model of acute pancreatitis induced by pancreatic duct ligation. ANIMALS Forty-eight adult female Wistar rats were randomized into two groups (n=24): control group and hyperbaric oxygen therapy group. INTERVENTION The second group was treated with a two-hour daily session of hyperbaric oxygen therapy at 2.5 ATA started 6 hours after pancreatic duct ligation. SETTING The two groups were divided into 3 subgroups of 8 rats each undergoing euthanasia on days 1, 3, and 7 after the acute pancreatitis induction. MAIN OUTCOME MEASURES The pancreas was evaluated according to the following histopathologic criteria: edema, hemorrhage, acinar necrosis and leukocyte infiltration. RESULTS Hyperbaric oxygen therapy was efficient in significantly reducing acinar necrosis on the first day (P=0.049) and the foci of hemorrhage on the seventh day (P=0.050). The edema and leukocyte infiltration did not show the expected reduction. CONCLUSION The utilization of a daily session of hyperbaric oxygen therapy at 2.5 ATA is efficient in reducing the hemorrhage and acinar necrosis but is not sufficient to reduce edema and leukocyte infiltration.
Reason for termination of breastfeeding and the length of breastfeeding.

BACKGROUND In third world countries the length of breastfeeding often has a major influence on child mortality, morbidity and nutritional status. When evaluating the impact of length of breastfeeding the reason why a mother terminates breastfeeding is usually not taken into consideration. METHODS Risk factors for termination of breastfeeding were studied in a prospective community study following 1678 children in Guinea Bissau, West Africa from birth to cessation of breastfeeding, migration or death. RESULTS The median weaning age was 22.6 months. Illness of the child, new pregnancy of the mother and illness of the mother were associated with significantly shorter lactation period compared with children weaned because they were 'healthy' or 'old enough'. These explanations had an impact independent of other determinants for weaning, including ethnic group, mother's age, mother's education, birth order and number of dead siblings. Weaning before 12 months of age was only associated with illness of the mother or child and new pregnancy and not with any socioeconomic or cultural factors. CONCLUSIONS Health workers should pay special attention to the encouragement of breastfeeding in connection with illness of the mother or child; these considerations may also be important in the planning of breastfeeding promotion campaigns. Since premature termination of breastfeeding is associated with new pregnancy, family planning should be part of any breastfeeding promotion programme.
Understanding the Relationship Between Perceived Authenticity and Well-Being

A central tenet of many prominent philosophical and psychological traditions is that personal authenticity facilitates psychological well-being. This idea, however, is at odds with numerous perspectives arguing that it is difficult, if not impossible, to really know one's self, or the true self may not even exist. Moreover, empirical findings suggest that reports of authenticity are often contaminated by positively valenced behavior, further potentially undermining the validity of authenticity measures. Despite these concerns, we argue that subjective feelings of authenticity do uniquely contribute to well-being. Specifically, we argue that the relationship between perceived authenticity and well-being may be understood from a social-cognitive lay theory perspective that we label “true-self-as-guide,” that suggests people use these feelings of authenticity as a cue to evaluate whether they are living up to a shared cultural value of what it means to live a good life. We end with a call for future research on the antecedents of perceived authenticity, boundary conditions for the consequences of personal authenticity, and discuss cultural differences in true-self-as-guide lay theories.
Associating Unseen Events

In prior work, we developed a computational model of how episodic associations between words are formed. Simulating associative learning, the model indicated that strongly associated semantically unrelated words facilitate the episodic association of other exemplars included in their semantic neighborhoods. This prediction was supported empirically by the present study. First, the incidental formation of strong associations between unrelated words, such as dog and table, improved cued recall of weak associations formed incidentally between semantic neighbors, like cat and chair. Second, deciding that two words were semantically unrelated was facilitated by forming strong associations between other words in their respective semantic neighborhoods, even if the tested pair was not presented at study. Together with the computational model, the present results demonstrate that forming episodic associations between words can implicitly mediate the association of other exemplars from the same semantic categories and reveal a mechanism by which the semantic system contributes to the formation of new episodic associations.
The protein kinase Sch9 is a key regulator of sphingolipid metabolism in Saccharomyces cerevisiae

Sphingolipids play crucial roles in the determination of growth and survival of eukaryotic cells. The budding yeast protein kinase Sch9 is not only an effector, but also a regulator of sphingolipid metabolism. This new function provides a crucial link between nutrient and sphingolipid signaling.
The host of GRB 060206: kinematics of a distant galaxy

Context. GRB afterglow spectra are sensitive probes of interstellar matter along the line-of-sight in their host galaxies, as well as in intervening galaxies. The rapid fading of GRBs makes it very difficult to obtain spectra of sufficient resolution and S/ Nt o allow for these kinds of studies. Aims. We investigate the state and properties of the interstellar medium in the host of GRB 060206 at z = 4.048 with a detailed study of groundstate and finestructure absorption lines in an early afterglow spectrum. This allows us to derive conclusions on the nature and origin of the absorbing structures and their connection to the host galaxy and/or the GRB. Methods. We used early (starting 1.6 h after the burst) WHT/ISIS optical spectroscopy of the afterglow of the gamma-ray burst GRB 060206 detecting a range of metal absorption lines and their finestructure transitions. Additional information is provided by the afterglow lightcurve. The resolution and wavelength range of the spectra and the bright afterglow have facilitated a detailed study and fitting of the absorption line systems in order to derive column densities. We also used deep imaging to detect the host galaxy and probe the nature of an intervening system at z = 1.48 seen in absorption in the afterglow spectra. Results. We detect four discrete velocity systems in the resonant metal absorption lines, best explained by shells within and/or around the host created by starburst winds. The finestructure lines have no less than three components with strengths decreasing from the redmost components. We therefore suggest that the finestructure lines are best explained as being produced by UV pumping from which follows that the redmost component is the one closest to the burst where N v was detected as well. The host is detected in deep HST imaging with F814WAB = 27.48 ± 0.19 mag and a 3σ upper limit of H = 20.6 mag (Vega) is achieved. A candidate counterpart for the intervening absorption system is detected as well, which is quite exceptional for an absorber in the sightline towards a GRB afterglow. The intervening system shows no temporal evolution as claimed by Hao et al. (2007, ApJ, 659, 99), which we prove from our WHT spectra taken before and Subaru spectra taken during those observations.
Partial Least Squares (PLS) Structural Equation Modeling (SEM) for Building and Testing Behavioral Causal Theory: When to Choose It and How to Use It

Problem: Partial least squares (PLS), a form of structural equation modeling (SEM), can provide much value for causal inquiry in communication-related and behavioral research fields. Despite the wide availability of technical information on PLS, many behavioral and communication researchers often do not use PLS in situations in which it could provide unique theoretical insights. Moreover, complex models comprising formative (causal) and reflective (consequent) constructs are now common in behavioral research, but they are often misspecified in statistical models, resulting in erroneous tests. Key concepts: First-generation (1G) techniques, such as correlations, regressions, or difference of means tests (such as ANOVA or t-tests), offer limited modeling capabilities, particularly in terms of causal modeling. In contrast, second-generation techniques (such as covariance-based SEM or PLS) offer extensive, scalable, and flexible causal-modeling capabilities. Second-generation (2G) techniques do not invalidate the need for 1G techniques however. The key point of 2G techniques is that they are superior for the complex causal modeling that dominates recent communication and behavioral research. Key lessons: For exploratory work, or for studies that include formative constructs, PLS should be selected. For confirmatory work, either covariance-based SEM or PLS may be used. Despite claims that lower sampling requirements exist for PLS, inadequate sample sizes result in the same problems for either technique. Implications: SEM's strength is in modeling. In particular, SEM allows for complex models that include latent (unobserved) variables, formative variables, chains of effects (mediation), and multiple group comparisons of these more complex relationships.
RETRACTED ARTICLE: Using fatherhood as a mechanism of change in substance abuse treatment for Hispanic men

This practice corner focuses on an overlooked population— Hispanic men who are substance users—and focuses on the need for culturally attuned prevention programs and practice that focus on the role of the father. Fatherhood for Hispanics, specifically, is a critical period in life where change and opportunity is possible. This article proposes for practice and treatment aimed at substance-abusing Hispanic men to capitalize on fatherhood, emphasizing a strengths-based prevention model utilizing identity theory to help reduce health disparities.
