An Intelligent technical analysis using neural network

Article history: Received October 16 2010 Received in revised form 14 February 2011 Accepted 14 February 2011 Available online 15 February 2011 Technical analysis has been one of the most popular methods for stock market predictions for the past few decades. There have been enormous technical analysis methods to study the behavior of stock market for different kinds of trading markets such as currency, commodity or stock. In this paper, we propose two different methods based on volume adjusted moving average and ease of movement for stock trading. These methods are used with and without generalized regression neural network methods and the results are compared with each other. The preliminary results on historical stock price of 20 firms indicate that there is no meaningful difference between various proposed models of this paper. © 2011 Growing Science Ltd.

MySci Advisors: Establishing a Peer-Mentoring Program for First Year Science Student Support

Would you like to help your students adjust to university life? Perhaps you are simply interested in allowing them to feel more integrated into a department right from the start of their first year? These were the types of issues that we were hoping to address when we founded the MySci Advisors Program, a peer-mentoring group for first year students in the Faculty of Science at the University of Windsor. This program is run entirely on a volunteer basis with no working budget, so if you were considering starting a mentoring program but have been concerned about the cost of doing so, this essay may be of particular interest to you. MySci Advisors is only in its third year currently, so this essay is meant to focus on the lessons we have learned in the early establishment of the program. I outline some of the practices we have adopted for the program, some of the changes we have had to make along the way and provide some early evidence of success. It is my hope that others may be motivated to also form such a program or use this information to assist in their own early endeavours.
Predictors of Food Insecurity in Lewiston, Maine: A Community-Level Analysis

Food insecurity is a health hazard for those who experience it. At the national level, households that are poor, single parent, composed of racial minorities, and located in urban areas are more likely to be food insecure. However, less is known about food insecurity’s distribution at the community level. A standard food security questionnaire was used to conduct a telephone survey of food insecurity in Lewiston, Maine. Results were mapped in a geographic information system along with 2010 census data and previously collected data on Lewiston’s food stores. Logistic regression analysis revealed that fewer adults and the presence of children in the household, but not measures of urbanization and community poverty, predicted lower household food security. These results demonstrate that food insecurity is more widely disturbed in Lewiston, Maine, than might have been predicted and suggest that services to mitigate the impact of food insecurity should also be widely distributed.
The Nonequivalence of High School Equivalents

This article analyzes the causes and consequences of the growing proportion of high-school-certified persons who achieve that status by exam certification rather than through high school graduation. Examcertified high school equivalents are statistically indistinguishable from high school dropouts. Whatever differences are found among examcertified equivalents, high school dropouts and high school graduates are accounted for by their years of schooling completed. There is no cheap substitute for schooling. The only payoff to exam certification arises from its value in opening postsecondary schooling and training opportunities, but completion rates for exam-certified graduates are much lower in these activities than they are for ordinary graduates.
Survey on Latency Issues of Asynchronous MAC Protocols in Delay-Sensitive Wireless Sensor Networks

Energy-efficiency is the main concern in most Wireless Sensor Network (WSN) applications. For this purpose, current WSN MAC (Medium Access Control) protocols use duty-cycling schemes, where they consciously switch a node's radio between active and sleep modes. However, a node needs to be aware of (or at least use some mechanism to meet) its neighbors' sleep/active schedules, since messages cannot be exchanged unless both the transmitter and the receiver are awake. Asynchronous duty-cycling schemes have the advantage over synchronous ones to eliminating the need of clock synchronization, and to be conceptually distributed and more dynamic. However, the communicating nodes are prone to spend more time waiting for the active period of each other, which inevitably influences the one-hop delay, and consequently the cumulative end-to-end delay. This paper reviews current asynchronous WSN MAC protocols. Its main contribution is to study these protocols from the delay efficiency perspective, and to investigate on their latency. The asynchronous protocols are divided into six categories: static wake-up preamble, adaptive wake-up preamble, collaborative schedule setting, collisions resolution, receiver-initiated, and anticipation-based. Several state-of-the-art protocols are described following the proposed taxonomy, with comprehensive discussions and comparisons with respect to their latency.
Virtual TeleStroke support for the emergency department evaluation of acute stroke.

OBJECTIVES Telemedicine-enabled acute stroke consultation (TeleStroke) may be useful to determine eligibility for treatment with tissue plasminogen activator (tPA) and provide support to emergency departments without on-site stroke expertise. METHODS Emergency physicians consulted with stroke neurologists via two-way videoconferencing in the evaluation of patients with possible acute stroke. History, neurologic examination, and computed tomography of the head were reviewed to determine eligibility for treatment with tPA. Interpretations of computed tomography were compared for inter-rater reliability between the neurologist and the neuroradiologist using a conventional workstation. Videotape and written records were analyzed to determine time intervals, patient management, and user satisfaction. RESULTS The authors reviewed data from 24 patients evaluated over 27 months at an island-based hospital. The mean National Institutes of Health Stroke Scale score was 5.7 (range, 0-22). Fifteen patients arrived at the emergency department less than three hours after symptom onset; 12 were presented for TeleStroke consultation within three hours after symptom onset. Eight of these 12 (75%) had acute ischemic stroke, and six of these eight potentially eligible patients (75%) received intravenous tPA. There was very good agreement among all remote readers for detecting the one case of imaging exclusion (subdural hemorrhage). There were no protocol violations, and a mean (+/- SD) consult-to-needle time of 36 (+/- 15) minutes and door-to-needle time of 106 (+/- 22) minutes was achieved. Transfer was avoided in 11 patients. Physicians believed that TeleStroke consultation improved care in >95% of the cases. CONCLUSIONS TeleStroke videoconferencing can support emergency department-based evaluation of acute stroke and may facilitate tPA delivery in neurologically underserved facilities. A prospective, randomized trial is needed to determine if these systems are superior to traditional telephone consultation.
Effect of Audiometric Configuration on Threshold and Suprathreshold Auditory Steady-State Responses

Objective: The purpose of this study was to examine the correlation between auditory steady-state response (ASSR) thresholds and behavioral thresholds in hearing-impaired adults with two common audiometric configurations. A second goal was to compare suprathreshold ASSR growth functions in these two subject groups and to determine whether these growth functions could be used clinically to improve threshold estimation. Design: Thirty adults participated, including 10 subjects with normal hearing, 10 subjects with flat moderately severe sensorineural hearing loss, and 10 subjects with sloping high-frequency sensorineural hearing loss. The accuracy of ASSR threshold estimations for the frequencies of 500, 1000, 2000, and 4000 Hz was compared across groups. In addition, ASSRs were recorded at multiple suprathreshold intensity levels, and the growth of the response was compared across subject groups. Results: ASSR and behavioral thresholds were strongly correlated across all subjects, with no significant difference by audiometric configuration. Slightly poorer correlations were obtained in the normal-hearing subjects than in hearing-impaired subjects and for the 500-Hz test frequency compared with the higher stimulus frequencies. Subtraction and regression methods for predicting behavioral thresholds from ASSR thresholds were equally accurate. Suprathreshold amplitude growth was variable among individuals, but mean growth functions showed steeper slopes in hearing-impaired subjects than in normal-hearing subjects, particularly for the higher frequencies (2000 to 4000 Hz). However, there was not a significant difference in the slopes of amplitude growth functions between subjects with sloping versus flat audiometric configurations for these frequencies, and estimation of threshold from suprathreshold ASSR amplitude growth functions was not advantageous. Conclusions: ASSR thresholds accurately predicted behavioral threshold equally well for flat or sloping audiometric configurations. The accuracy of threshold estimation for either audiometric configuration and the similar growth function slopes may suggest that there is little spread of activation to neighboring regions of the cochlea when using multiple 100% AM stimuli in subjects with moderately sloping losses. The small amplitude of the ASSR response and individual variability may make threshold estimation based on extrapolation from suprathreshold ASSR responses impractical.
The Determinants of Bank Efficiency and Productivity Growth in the Central and Eastern European Banking Systems

In this paper we examine the determinants of the efficiency and productivity of the banking systems of seven central and east European countries during a five-year period, from 2004 to 2008. Two approaches are used to examine the efficiency of the banking industry in central and east European countries: stochastic frontier analysis and data envelopment analysis. The empirical results show that the average efficiency of banks in central and east European countries grew in the period analyzed. The improvement may be due to increased competition upon EU accession and the entry of foreign banks, as well as to extensive legislative changes that led banks to become more efficient. Based on the results, we see that the highest level of technical efficiency is recorded for the banking systems of Romania and the Czech Republic, and the lowest is recorded for Slovenia. Looking at the average efficiency scores for each country, we observe significant variation across the banking systems of the central and east European countries. Technical efficiency value estimates with the stochastic frontier analysis method range from 0.6275 in Slovakia to 0.8644 in Romania. To assess the level of productivity growth of the banking industry, a Malmquist productivity index is calculated using linear programming. In the analyzed period, on average, the productivity of banks had increased in 2008 by approximately 24.27 percent from 2004, an increase due especially to technological modification.
The Changing Nature of Currency Crises

Currency crises that have been observed in recent years are not a new phenomenon, but the main features of the crises in Latin America in the 1970s and early 1980s are quite different from the crisis in Europe in 1992. Theoretical literature has evolved over time to account for the changing nature of these crises. While many theoretical and empirical papers have been written about various episodes of these crises, the change in their mechanism over time has not been demonstrated well. This paper fills the gap in the literature by graphically depicting the main features of these crises. Such a visual analysis should allow the reader to better understand and follow the changes in the mechanisms over time. Copyright Blackwell Publishers Ltd, 2004.
The Viability of Somaliland: Internal Constraints and Regional Geopolitics

Throughout the Cold War, secession was taboo in the state-centric international system. However, the breakup of the Soviet Union, Yugoslavia and Czechoslovakia, the independence of Eritrea and East Timor as well as recent developments in Kosovo seemed to weaken the principle of inviolable state boundaries. From one point of view, these events may have far-reaching repercussions for Africa where borders are generally considered to be more arbitrary than elsewhere (Herbst 1989). And no other area in Africa is closer to secession than the northern region of Somalia — an area whose boundaries largely correspond to the former British Protectorate of Somaliland. (The British and Italian colonies of Somaliland became the Republic of Somalia in 1960.)
Estimating individual rates of discount: a meta-analysis

In this article, we present the results from a meta-analysis conducted over 44 experimental and field studies, which report individual discount rate estimates. We find in our research that the experimental design of a study has a decisive impact on these estimates, and conclude that meta-analysis, in the case of individual discount rates, has a low transfer value.
Taxes and the Labor Market

We estimate the effect of exogenous changes in taxes on the US unemployment rate and on several other labor market variables. Our estimates are based on a revised version of the Romer and Romer (2010) narrative record of exogenous tax innovations, with the additional benefit of distinguishing between capital income and labor income taxes. We first show that accounting for the difference between automatic and discretionary tax changes in the revised specification is crucial in order to obtain an unbiased measure of the tax multipliers. We then obtain the following main results. An increase in tax receipts of one percent of GDP has a sizeable positive impact on the unemployment rate, and a negative impact on hours worked, labor market tightness and job finding probability. The effect on GDP is also sizeable, but somewhat in the mid range of other values found in the literature, due to the fact that we account for the difference between discretionary and automatic changes in tax revenues. The effect on the unemployment rate of variations in business taxes is larger than that of personal income taxes. We suggest that the latter result poses interesting challenges for future research.
Constitutive activation of gene expression by thyroid hormone receptor results from reversal of p53-mediated repression

Thyroid hormone receptor (T3R) is a member of the steroid hormone receptor gene family of nuclear hormone receptors. In most cells T3R activates gene expression only in the presence of its ligand, L-triiodothyronine (T3). However, in certain cell types (e.g., GH4C1 cells) expression of T3R leads to hormone-independent constitutive activation. This activation by unliganded T3R occurs with a variety of gene promoters and appears to be independent of the binding of T3R to specific thyroid hormone response elements (TREs). Previous studies indicate that this constitutive activation results from the titration of an inhibitor of transcription. Since the tumor suppresser p53 is capable of repressing a wide variety of gene promoters, we considered the possibility that the inhibitor is p53. Evidence to support this comes from studies indicating that expression of p53 blocks T3R-mediated constitutive activation in GH4C1 cells. In contrast with hormone-independent activation by T3R, p53 had little or no effect on T3-dependent stimulation which requires TREs. In addition, p53 mutants which oligomerize with wild-type p53 and interfere with its function also increase promoter activity. This enhancement is of similar magnitude to but is not additive with the stimulation mediated by unliganded T3R, suggesting that they target the same factor. Since p53 mutants are known to target wild-type p53 in the cell, this suggests that T3R also interacts with p53 in vivo and that endogenous levels of p53 act to suppress promoter activity. Evidence supporting both functional and physical interactions of T3R and p53 in the cell is presented. The DNA binding domain (DBD) of T3R is important in mediating constitutive activation, and the receptor DBD appears to functionally interact with the N terminus of p53 in the cell. In vitro binding studies indicate that the T3R DBD is important for interaction of T3R with p53 and that this interaction is reduced by T3. These findings are consistent with the in vivo studies indicating that p53 blocks constitutive activation but not ligand-dependent stimulation. These studies provide insight into mechanisms by which unliganded nuclear hormone receptors can modulate gene expression and may provide an explanation for the mechanism of action of the v-erbA oncoprotein, a retroviral homolog of chicken T3R alpha.

Does co-morbid depressive illness magnify the impact of chronic physical illness? A population-based perspective

Objective. To examine the relative and combined impact of depressive and chronic physical conditions on functional status and health-care use in the general population. Method. Canadian, representative, population-based cross-sectional survey (n=130880). Major depressive disorder (MDD) in the past 12 months was assessed by structured interview, and physical disorders, activity reduction, role impairment and work absence by self-report. The relative impact of MDD and six common chronic physical illnesses (asthma, arthritis, back problems, chronic obstructive pulmonary disease, heart disease and diabetes) was estimated using multivariate regression, adjusting for sociodemographic characteristics and overall chronic physical illness burden. Results. After adjusting for sociodemographic characteristics, alcohol dependence and chronic physical illness burden, the presence of co-morbid MDD was associated with significantly greater (approximately double the) likelihood of health-care utilization and increased functional disability and work absence compared to the presence of a chronic physical illness without co-morbid MDD. This impact of MDD was seen across each of the six chronic physical illnesses examined in this study, with the strongest associations seen for work absence. Conclusions. These observations confirm prior findings of a strong association at the population level between major depression and health-care use and role impairment among persons with chronic physical disorders. They also point to the significant impact of co-morbid major depression on health-care seeking, disability and work absence in persons with chronic physical illness, underscoring the need for greater efforts to design and test the impact of detection and treatment programs for such individuals.
Drinking Water Source and Chlorination Byproducts I. Risk of Bladder Cancer

We conducted a population-based case-control study of bladder cancer in Iowa in 1986–1989 to evaluate the risk posed by tapwater containing chlorination byproducts. We combined information about residential history, drinking water source, beverage intake, and other factors with historical data from water utilities and measured contaminant levels to create indices of past exposure to chlorination byproducts. The study comprised 1,123 cases and 1,983 controls who had data relating to at least 70% of their lifetime drinking water source. After we adjusted for potential confounders, we calculated odds ratios for duration of chlorinated surface water of 1.0 (referent), 1.0, 1.1, 1.2, and 1.5 for 0, 1–19, 20–39, 40–59, and ≥60 years of use. We also found associations with total and average lifetime byproduct intake, as represented by trihalomethane estimates. Positive findings were restricted to men and to ever-smokers. Among men, odds ratios were 1.0 (referent), 1.1, 1.3, 1.5, and 1.9, and among ever-smokers, 1.0, 1.1, 1.3, 1.8, and 2.2, after adjustment for intensity and timing of smoking. Among nonsmoking men and women, regardless of smoking habit, there was no association. Among men, smoking and exposure to chlorinated surface water mutually enhanced the risk of bladder cancer. The overall association of bladder cancer risk with duration of chlorinated surface water use that we found is consistent with the findings of other investigations, but the differences in risk between men and women, and between smokers and nonsmokers, have not been widely observed.
Wage Bargaining Structure, Employment and Economic Integration

It is widely believed that the integration of European economies will have little impact on labour mobility. This does not mean, however, that European labour markets will be unaffected by the process of economic integration. In this paper we show that with increased competition from closer economic integration, the hump-shaped pattern summarizing the relationship between economic performance and the degree of centralization in wage bargaining (Calmfors and Driffill, 1988) flattens out. As a consequence, the importance of the position of a particular economy on the wage-bargaining scale diminishes. We find, however, that the post-integration wage-price structure is closer to the configuration familiar to decentralized economies. It can be inferred that the adjustment to the new environment could be more difficult for economies characterized by centralized wage bargaining.
Is Inflation Targeting Feasible in Poland

In this paper we analyze whether inflation targeting is feasible in Poland. There are at least three prerequisites for successful inflation targeting: 1) central bank independence, 2) a high degree of central bank accountability, transparency, and communication to the public, and 3) a predictable and stable relationship between inflation and the instruments of monetary policy. While the first two prerequisites are relatively easy to analyze, the third criterion requires formal statistical analysis, which we undertake in this paper. The first two prerequisites for targeting are found to be met in Poland, and the empirical analysis shows some evidence of significant relationships between inflation and monetary instruments in Poland. Hence inflation targeting appears feasible in Poland.
