Stock Market Investment Advice: A Social Network Approach

Making investment decision on various available stocks in the market is a challenging task. Econometric and statistical models, as well as machine learning and data mining techniques, have proposed heuristic based solutions with limited long-range success. In practice, the capabilities and intelligence of financial experts is required to build a managed portfolio of stocks. However, for non-professional investors, it is too complicated to make subjective judgments on available stocks and thus they might be interested to follow an expert's investment decision. For this purpose, it is critical to find an expert with similar investment preferences. In this work, we propose to benefit from the power of Social Network Analysis in this domain. We first build a social network of financial experts based on their publicly available portfolios. This social network is then used for further analysis to recommend an appropriate managed portfolio to non-professional investors based on their behavioral similarities to the expert investors. This approach is evaluated through a case study on real portfolios. The result shows that the proposed portfolio recommendation approach works well in terms of Sharpe ratio as the portfolio performance metric.
Reassessing Support for Islam and Democracy in the Arab World?: Evidence from Egypt and Jordan

A cross the Middle East, support for democracy is striking. Regional survey data throughout the Arab world indicates that levels of support for democracy enjoy consid erable majority support.1 However, the Arab world has yet to see its first full-fledged demo cratic state. Studies examining the potential for democracy in the region often analyze institutional reforms that correspond with lib eral democratic principles. Yet, students of Middle Eastern politics understand that exist ing institutional reforms, such as parliamen tary elections and greater freedoms within civil society, have done little to enhance democracy in the region. In fact, the liberaliz ing tendencies of the 1990s have further solid ified authoritarian rule.2 Although these reforms have allowed for greater civic and political participation, they have also been accompanied by further repression and the continued monopolization of regime power. Today, democracy in the Arab world is, at best, a remote possibility. In this conundrum of democratization, where institutional liberalizing reforms have been linked to further authoritarian consolidation and
Social Work Education and Practice in the Jail Setting

ABSTRACT Despite social work's historical commitment to social justice and the strength of the profession in terms of the number of persons holding master degrees in social work, we are guilty of ignoring the needs which confront us daily from inside one of the oldest institutions in this country: the jail. The jail setting offers social workers the opportunity to simultaneously address the various critical needs of a multi-client system, a system which includes rising numbers of persons with serious and persistent mental illnesses, overworked and underappreciated detention personnel, and an often tedious and impersonal judicial process. In this article, the fit between jail system needs and social work education is explored and encouraged. Envisioned is an interdependent relationship where the jail provides the Academy and its students access to an environment rich and ripe for study and, in turn, the Academy offers the jail both direct services and indirect support for identifying and intervening in inm.
Effect of brown rice, white rice, and brown rice with legumes on blood glucose and insulin responses in overweight Asian Indians: a randomized controlled trial.

BACKGROUND Improving the carbohydrate quality of the diet by replacing the common cereal staple white rice (WR) with brown rice (BR) could have beneficial effects on reducing the risk for diabetes and related complications. Hence we aimed to compare the effects of BR, WR, and BR with legumes (BRL) diets on 24-h glycemic and insulinemic responses among overweight Asian Indians. SUBJECTS AND METHODS Fifteen overweight (body mass index, ≥23 kg/m(2)) Asian Indians without diabetes who were 25-45 years old participated in a randomized crossover study. Test meals (nonisocaloric, ad libitum) were identical except for the type of rice and the addition of legumes (50 g/day) and were provided for 5 consecutive days. Glucose profiles were assessed using the Medtronic MiniMed (Northridge, CA) iPro™2 continuous glucose monitoring device. The mean positive change from baseline glucose concentration was calculated as the daily incremental area under the curve (IAUC) on each test day for 5 days and averaged. Fasting serum insulin was measured prior to and at the end of each test diet. RESULTS The percentage difference in 5-day average IAUC was 19.8% lower in the BR group than in the WR group (P=0.004). BRL further decreased the glycemic response (22.9% lower compared with WR (P=0.02). The 5-day percentage change in fasting insulin was 57% lower (P=0.0001) for the BR group and 54% lower for the BRL group compared with the 5-day percentage change observed in the WR group. The glycemic and insulinemic responses to the BR and BRL diets were not significantly different. CONCLUSIONS Consumption of BR in place of WR can help reduce 24-h glucose and fasting insulin responses among overweight Asian Indians.

Oral low-dose tacrolimus therapy for refractory hemophagocytic syndrome associated with systemic lupus erythematosus

Hemophagocytic syndrome (HPS) is an unusual disorder associated with systemic lupus erythematosus (SLE). A 64-year-old woman was admitted because of fever and urticarial vasculitis. Laboratory data revealed pancytopenia and immunological abnormalities, suggesting elevated disease activity. Prednisolone monotherapy failed to improve the pancytopenia despite the amelioration of other clinical findings. Because her condition was suggestive of HPS, tacrolimus at 2–3 mg/day was added to the prednisolone regimen. Eventually, the pancytopenia improved and prednisolone could be effectively tapered. Tacrolimus could be an additional or alternative modality for treating refractory HPS.
Clustering of Resting State Networks

Background The goal of the study was to demonstrate a hierarchical structure of resting state activity in the healthy brain using a data-driven clustering algorithm. Methodology/Principal Findings The fuzzy-c-means clustering algorithm was applied to resting state fMRI data in cortical and subcortical gray matter from two groups acquired separately, one of 17 healthy individuals and the second of 21 healthy individuals. Different numbers of clusters and different starting conditions were used. A cluster dispersion measure determined the optimal numbers of clusters. An inner product metric provided a measure of similarity between different clusters. The two cluster result found the task-negative and task-positive systems. The cluster dispersion measure was minimized with seven and eleven clusters. Each of the clusters in the seven and eleven cluster result was associated with either the task-negative or task-positive system. Applying the algorithm to find seven clusters recovered previously described resting state networks, including the default mode network, frontoparietal control network, ventral and dorsal attention networks, somatomotor, visual, and language networks. The language and ventral attention networks had significant subcortical involvement. This parcellation was consistently found in a large majority of algorithm runs under different conditions and was robust to different methods of initialization. Conclusions/Significance The clustering of resting state activity using different optimal numbers of clusters identified resting state networks comparable to previously obtained results. This work reinforces the observation that resting state networks are hierarchically organized.
A partition-based approach for identifying failing scan cells in scan-BIST with applications to system-on-chip fault diagnosis

We present a new partition-based fault diagnosis technique for identifying failing scan cells in a scan-BIST environment. This approach relies on a two-step scan chain partitioning scheme. In the first step, an interval-based partitioning scheme is used to generate a small number of partitions, where each element of a partition consists of a set of scan cells. In the second step, additional partitions are created using an earlier-proposed random-selection partitioning method. Two-step partitioning leads to higher diagnostic resolution than a scheme that relies only on random-selection partitioning, with only a small amount of additional hardware. The proposed scheme is especially suitable for a system-on-chip (SOC) composed of multiple embedded cores, where test access is provided by means of a TestRail that is threaded through the internal scan chains of the embedded cores. We present experimental results for the six largest ISCAS-89 benchmark circuits and for two SOCs crafted from some of the ISCAS-89 circuits.
Money Talks: Rebate Mechanisms in Reputation System Design

Reputation systems that rely on voluntary feedback from traders are important in creating and sustaining trust in markets. Feedback nevertheless is a public good, and providing it is often costly. We combine theory with a laboratory experiment to study the effect of a seller precommitment mechanism: Sellers have an option to commit by providing a rebate to reduce the buyer's feedback reporting cost before making purchasing decisions. Our theory predicts that this mechanism induces noncooperative sellers to cooperate in the listed-price market. Using a buyer--seller trust game with a unilateral feedback scheme, we find that the seller's rebate decision has a significant impact on the buyer's purchasing decision via signaling the seller's cooperative type. More importantly, market efficiency under the precommitment mechanism increases with the probability that sellers will provide a rebate. Compared with the no rebate mechanism market, more efficient trades can be achieved when the sellers offer a rebate to the buyers in the market with the rebate mechanism, even when the rebate does not cover the full cost of feedback reporting.

The Molecular Signature of the Stroma Response in Prostate Cancer-Induced Osteoblastic Bone Metastasis Highlights Expansion of Hematopoietic and Prostate Epithelial Stem Cell Niches

The reciprocal interaction between cancer cells and the tissue-specific stroma is critical for primary and metastatic tumor growth progression. Prostate cancer cells colonize preferentially bone (osteotropism), where they alter the physiological balance between osteoblast-mediated bone formation and osteoclast-mediated bone resorption, and elicit prevalently an osteoblastic response (osteoinduction). The molecular cues provided by osteoblasts for the survival and growth of bone metastatic prostate cancer cells are largely unknown. We exploited the sufficient divergence between human and mouse RNA sequences together with redefinition of highly species-specific gene arrays by computer-aided and experimental exclusion of cross-hybridizing oligonucleotide probes. This strategy allowed the dissection of the stroma (mouse) from the cancer cell (human) transcriptome in bone metastasis xenograft models of human osteoinductive prostate cancer cells (VCaP and C4-2B). As a result, we generated the osteoblastic bone metastasis-associated stroma transcriptome (OB-BMST). Subtraction of genes shared by inflammation, wound healing and desmoplastic responses, and by the tissue type-independent stroma responses to a variety of non-osteotropic and osteotropic primary cancers generated a curated gene signature (“Core” OB-BMST) putatively representing the bone marrow/bone-specific stroma response to prostate cancer-induced, osteoblastic bone metastasis. The expression pattern of three representative Core OB-BMST genes (PTN, EPHA3 and FSCN1) seems to confirm the bone specificity of this response. A robust induction of genes involved in osteogenesis and angiogenesis dominates both the OB-BMST and Core OB-BMST. This translates in an amplification of hematopoietic and, remarkably, prostate epithelial stem cell niche components that may function as a self-reinforcing bone metastatic niche providing a growth support specific for osteoinductive prostate cancer cells. The induction of this combinatorial stem cell niche is a novel mechanism that may also explain cancer cell osteotropism and local interference with hematopoiesis (myelophthisis). Accordingly, these stem cell niche components may represent innovative therapeutic targets and/or serum biomarkers in osteoblastic bone metastasis.

The Moral Emotions

Morality dignifies and elevates. When Adam and Eve ate the forbidden fruit, God said "Behold, the man is become as one of us, to know good and evil" (Gen. 3:22). In many of the world's religious traditions, the good go up, to heaven or a higher rebirth, and the bad go down, to hell or a lower rebirth. Even among secular people, moral motives are spoken of as the "highest" and "noblest" motives, whereas greed and lust are regarded as "baser" or "lower" instincts. Morality is therefore like the temple on the hill of human nature: It is our most sacred attribute, a trait that is often said to separate us from other animals and bring us closer to God. For 2,400 years, the temple has been occupied by the high priests of reason. Plato (4th century B.C./1949) presented a model of a divided self in which reason, firmly ensconced in the head, rules over the passions, which rumble around in the chest and stomach (Timaeus, 69). Aristotle had a similar conception of reason as the wise master and emotion as the foolish slave: "anger seems to listen to reason, but to hear wrong, like hasty servants, who run off before they have heard everything their master tells them, and fail to do what they were ordered, or like dogs, which bark as soon as there is a knock without waiting to see if the visitor is a friend" (Ethics, 1962, 1149a). Throughout the long history of moral philosophy, the focus has generally been on moral reasoning, whereas the moral emotions have been regarded with some suspicion (Solomon, 1993). Even when moral psychology finally separated itself from moral philosophy and began to make its own empirical contributions, it invested almost all of its capital in the study of moral reasoning. Piaget (1932/1965) studied the child's developing understanding of fairness and rules. Piaget to provide both a measurement tool and a conceptual framework for the study of moral reasoning, and the field grew rapidly. Kohlberg's work was an important part of the cognitive revolution, demonstrating that morality, like language, could be studied as a system of transformations of underlying cognitive constructs. Yet as the cognitive revolution matured, researchers recognized the growing need for a parallel "affect revolu-tion" (Tomkins, 1981). Table 45.1 shows that this revolution has indeed taken place. for the moral emotions have been growth stocks in the 1980s and …
Dynamic water exercise in individuals with late poliomyelitis.

OBJECTIVE To evaluate the specific effects of general dynamic water exercise in individuals with late effects of poliomyelitis. DESIGN Before-after tests. SETTING A university hospital department. PARTICIPANTS Twenty-eight individuals with late effects of polio, 15 assigned to the training group (TG) and 13 to the control group (CG). INTERVENTION The TG completed a 40-minute general fitness training session in warm water twice weekly. Assessment instruments included the bicycle ergometer test, isokinetic muscle strength, a 30-meter walk indoors, Berg balance scale, a pain drawing, a visual analog scale, the Physical Activity Scale for the Elderly, and the Nottingham Health Profile (NHP). MAIN OUTCOME MEASURES Peak load, peak work load, peak oxygen uptake, peak heart rate (HR), muscle function in knee extensors and flexors, and pain dimension of the NHP. RESULTS The average training period was 5 months; compliance was 75% (range, 55-98). No negative effects were seen. The exercise did not influence the peak work load, peak oxygen uptake, or muscle function in knee extensors compared with the controls. However, a decreased HR at the same individual work load was seen, as well as a significantly lower distress in the dimension pain of the NHP. Qualitative aspects such as increased well-being, pain relief, and increased physical fitness were reported. CONCLUSIONS A program of nonswimming dynamic exercises in heated water has a positive impact on individuals with late effects of polio, with a decreased HR at exercise, less pain, and a subjective positive experience. The program was well tolerated (no adverse effects were reported) and can be recommended for this group of individuals.
Ieee Transactions on Signal Processing 1 Soi-kf: Distributed Kalman Filtering with Low-cost Communications Using the Sign of Innovations

—When dealing with decentralized estimation, it is important to reduce the cost of communicating the distributed observations—a problem receiving revived interest in the context of wireless sensor networks. In this paper, we derive and analyze distributed state estimators of dynamical stochastic processes, whereby the low communication cost is effected by requiring the transmission of a single bit per observation. Following a Kalman filtering (KF) approach, we develop recursive algorithms for distributed state estimation based on the sign of innovations (SOI). Even though SOI-KF can afford minimal communication overhead, we prove that in terms of performance and complexity it comes very close to the clairvoyant KF which is based on the analog-amplitude observations. Reinforcing our conclusions, we show that the SOI-KF applied to distributed target tracking based on distance-only observations yields accurate estimates at low communication cost.
Bacterial Compatibility in Combined Inoculations Enhances the Growth of Potato Seedlings

The compatibility of strains is crucial for formulating bioinoculants that promote plant growth. We herein assessed the compatibility of four potential bioinoculants isolated from potato roots and tubers (Sphingomonas sp. T168, Streptomyces sp. R170, Streptomyces sp. R181, and Methylibium sp. R182) that were co-inoculated in order to improve plant growth. We screened these strains using biochemical tests, and the results obtained showed that R170 had the highest potential as a bioinoculant, as indicated by its significant ability to produce plant growth-promoting substances, its higher tolerance against NaCl (2%) and AlCl3 (0.01%), and growth in a wider range of pH values (5.0–10.0) than the other three strains. Therefore, the compatibility of R170 with other strains was tested in combined inoculations, and the results showed that the co-inoculation of R170 with T168 or R182 synergistically increased plant weight over un-inoculated controls, indicating the compatibility of strains based on the increased production of plant growth promoters such as indole-3-acetic acid (IAA) and siderophores as well as co-localization on roots. However, a parallel test using strain R181, which is the same Streptomyces genus as R170, showed incompatibility with T168 and R182, as revealed by weaker plant growth promotion and a lack of co-localization. Collectively, our results suggest that compatibility among bacterial inoculants is important for efficient plant growth promotion, and that R170 has potential as a useful bioinoculant, particularly in combined inoculations that contain compatible bacteria.
Variable selection in covariate dependent random partition models: an application to urinary tract infection

Lower urinary tract symptoms can indicate the presence of urinary tract infection (UTI), a condition that if it becomes chronic requires expensive and time consuming care as well as leading to reduced quality of life. Detecting the presence and gravity of an infection from the earliest symptoms is then highly valuable. Typically, white blood cell (WBC) count measured in a sample of urine is used to assess UTI. We consider clinical data from 1341 patients in their first visit in which UTI (i.e. WBC ≥1 ) is diagnosed. In addition, for each patient, a clinical profile of 34 symptoms was recorded. In this paper, we propose a Bayesian nonparametric regression model based on the Dirichlet process prior aimed at providing the clinicians with a meaningful clustering of the patients based on both the WBC (response variable) and possible patterns within the symptoms profiles (covariates). This is achieved by assuming a probability model for the symptoms as well as for the response variable. To identify the symptoms most associated to UTI, we specify a spike and slab base measure for the regression coefficients: this induces dependence of symptoms selection on cluster assignment. Posterior inference is performed through Markov Chain Monte Carlo methods. Copyright © 2015 John Wiley & Sons, Ltd.
