Stock prices and house prices: Which one affects the other

Stock and house are two major assets which play important roles in the balance sheet of Iranian households. Changes in the two markets have a large influence on wealth and the general economy. The purpose of this study is to examine the relationship between stock and house prices over a thirtyyear period using vector auto-regression (VAR). Using yearly data for the period from 1985 to 2013, we conducted a Granger-causality test and Impulse response functions (IRF). The causality test is performed with control variables and the results supply evidence on the bidirectional relationship between house price and stock price. Impulse response function is estimated in order to investigate the size and timing of the causality. The IRF concludes that, when the impulse is stock price, every response of house price is most positive and the values fluctuate around the line zero at each time period.

A Study on Cross-Cultural Adaptation of Mainland Chinese Students in Taiwan from the Perspective of Self-Identity

At present, there are a total of 9462 mainland Chinese students with formal degrees in Taiwan. There are a large number of mainland students studying in Taiwan, but there are few studies on their adaptation to life and learning in Taiwan. This study takes the view of self-identity, to explore the cross-cultural adaptation of mainland students in Taiwan, this study conducted in-depth interviews with 7 mainland students from the National Kaohsiung University of Hospitality and Tourism by means of qualitative research and literature Review. The factors of cross-cultural adaptation divided into life adaptation, cultural adaptation, learning adaptation, interactive adaptation and leisure adaptation. A total of 204 valid questionnaires were received, and structural equation model analysis was carried out with SPSS22 and LISREL852. The results showed that the view of self-identity could be divided into value identity, social identity, group identity and personality identity，the value identity point of view is the most important. Secondly, self-identity view has positive and significant effects on life adaptation, cultural adaptation, learning adaptation, interactive adaptation and leisure adaptation. Self-identity view can be divided into high self-identity group, middle self-identity group and low self-identity group, while high self-identity view has high cross-cultural adaptation. Finally, in life adaptation, mainland students are more concerned with the consumption environment, medical care and entertainment, transportation and related living facilities; in learning adaptation, mainland student pays more attention to language and writing; in interactive adaptation, mainland student pays more attention to the interaction of administrative personnel. This study puts forward relevant suggestions, hoping to arouse the attention of Taiwan authorities and enrollment schools, achieve convergence management, and also hope to provide reference and reference for the vast number of mainland students to apply for study in Taiwan.
The Impact of the Extrinsic Innovative Entrepreneurs Motivation and the Knowledge-Based Competitive Conditions on Technological Innovation

In this research, we will try to show to what extent the competitive environment in the knowledge era and the extrinsic individual motivation of innovative entrepreneurs could enhance technological innovation in newlyestablished enterprises. A study on a sample of 105 new Tunisian enterprises deemed innovative in a national and regional innovative economic environment revealed 'the following: The nature of the market demand and the dissemination of knowledge by firms have a positive effect on the improvement of technological innovation, while efforts to adapt to market changes, the entrepreneurs' motivation extrinsic system to innovate, the state of competition and the evolution of that market had no effect on it.
Effects of Increased Access to Infertility Treatment on Infant and Child Health Outcomes: Evidence from Health Insurance Mandates

This paper examines the association between use of infertility treatment and infant and child health outcomes. Infertility treatment makes conception possible for many couples who otherwise would have been unable to reproduce. Many treatments also increase the chance of having a multiple birth, typically a more risky pregnancy. State insurance mandates compelling insurers to cover or offer to cover infertility treatment induce variation across states over time in access to subsidized infertility treatment. Using birth certificate data, this paper finds the infertility mandates are associated with a statistically significant 10 percent increase in twin births among older mothers. Twin pregnancies are typically more dangerous (and costly) than singleton pregnancies. Thus, even if the only effect of the mandates is to increase twin births, they have likely had a negative effect on infant health. For twins born to older mothers, the mandates are also associated with small but statistically significant negative effects on birth weight, gestation, and the 5-minute Apgar score. Effects for singletons born to older mothers are smaller in magnitude but still negative. Using Census data, the paper finds more mixed evidence about longer term effects of the mandates on child health. The findings for twin birth outcomes suggest that positive effects of investment by older mothers in their pregnancies are outweighed by negative impacts of either the infertility treatments themselves or by the selection into pregnancy of women with reduced fecundity.

Conflicting Selective Forces Underlying Seed Dispersal in the Endangered Plant Silene diclinis

Selective pressures underlying the distance of seed dispersal in Silene diclinis were evaluated in natural populations. We expected that high seed predation and high seedling density around mother plants would favor relatively long‐distance dispersal and that microhabitat conditions might favor short‐distance dispersal. We experimentally altered seed density and seed dispersal distance and found that seed predation by ants increased with density but not with distance. Observations of naturally occurring seedlings showed that their survival probability was higher at lower density and when closer to female plants. Overall, calculated cumulative survival probabilities (including both seed predation and seedling survival) favored limited dispersal. Observations of naturally occurring seedlings and adults showed a strongly clumped spatial population structure. Selection for reduced dispersal and the resulting reduction of colonization ability make S. diclinis populations extremely sensitive to environmental stochasticity, and in the long run, this could contribute to the extinction of this endangered species as a consequence of changing land‐use patterns.
AGSDFM: ACTIVE GUARD SERVICE DETECTOR FILTRATION MODEL FOR PROTECTING DATABASE AGAINST SQL INJECTION ATTACK

A large number of web applications, especially those deployed by companies for e-business operations involve high reliability, efficiency and confidentiality. Such applications are often written in script languages like PHP embedded in HTML, allowing establishing connection to databases, retrieving data, and putting them in the Web. One of the most common in web application attacks is SQL Injection. SQL injection is an attack in which malicious code is inserted into strings that are later passed to an instance of SQL Server for parsing and execution. Any procedure that constructs SQL statements should be reviewed for injection vulnerabilities because SQL Server will execute all syntactically valid queries that it receives. In this paper, an attempt has been made to classify the SQL Injection attacks based on the vulnerabilities in web applications. A brief review of the existing approaches for the detection of SQL injection attack also have been presented. This paper proposes a novel specification-based methodology for the prevention of SQL injection Attacks. The two most important advantages of the new approach against existing analogous mechanisms are that, first, it prevents all forms of SQL injection attacks; second, Current technique does not allow the user to access database directly in database server. The innovative technique “Web Service Oriented XPATH Authentication Technique” is to detect and prevent SQL- Injection Attacks in database the deployment of this technique is by generating functions of two filtration models that are Active Guard and Service Detector of application scripts additionally allowing seamless integration with currently-deployed systems. We have implemented our approach using . Net platform. Our result shows that we successfully detect the attacker and prevent them to breach the security.
Correlation and path coefficient analysis of body weight and morphometric traits of two exotic genetic groups of ducks in Nigeria

The study aimed at describing objectively the interdependence between body weight (BWT) and morphometric traits in Khaki Campbell and Pekin ducks using multivariate path analysis technique. Measurements were taken on one hundred and ninety seven (197) randomly selected 10-week old Khaki Campbell and Pekin ducks, respectively in Plateau State, Nigeria. The birds were reared on deep litter in a semi-intensive system where they were kept in a fenced area provided with water ponds and locked up in the poultry house during the night. The body parts measured were, body length (BDL); thigh length (THL); thigh circumference (THC); breast circumference (BTC); bill length (BLL); neck length (NKL); neck circumference (NKC); shank length (SHL); shank width (SHW); total leg length (TLL) and wing length (WL). General linear model was used to study genotype and sex effects. Pekin ducks had a superior advantage (p<0.05) over their Khaki Campbell counterparts in all the body parameters estimated. Sexual dimorphism (p<0.05) was in favour of male ducks. Pairwise phenotypic correlations between BWT and morphometric traits were positive and significant (p<0.01), ranging from 0.38-0.95 and 0.35-0.92 for Khaki Campbell and Pekin ducks, respectively. Path analysis revealed that BDL was the variable of utmost importance directly influencing BWT in male Khaki Campbell and Pekin ducks (path coefficient=0.535 and 0.508, respectively; p<0.01) while BTC and SHL were the most responsible parameters affecting BWT in female Khaki Campbell and Pekin ducks [path coefficient=0.594 (P<0.01) and 1.197 (p<0.05), respectively]. The optimum regression models for the prediction of BWT in Khaki Campbell ducks included BDL, SHL, BTC and NKC (male) and BDL, WNL and BTC (female); while in their Pekin counterparts, BDL, BLL and BTC (male) and BDL and SHL (female) were incorporated.

A critical discourse analysis of teacher-student relationships in a third-grade literacy lesson: Dynamics of microaggression

Abstract This study focuses on a recording from a week of third-grade classroom sessions. The recording was used to train new teachers in a certification program and provided data for a learning community that was studying classroom discourse. The third-grade teacher was described as being “outstanding” and “culturally responsive” by the university professor who had been using the recording to train teacher candidates. The teacher was indeed innovative in supporting cultural diversity and was responsive to all students throughout the week, except during a particular literacy lesson, the subject of this study. Critical discourse analysis revealed prioritizing White males, disrespecting a Mexican-American boy and neglecting females. The recording was later withdrawn from the certification program because it did not reflect exemplary teaching, yet its initial use points to an urgent educational problem: even experienced teachers exhibit microaggressions toward students of color and female students, and experts in teacher education do not readily recognize them when they occur. Microaggressions can appear subtle and inconsequential, yet they have a negative impact on the teacher–student relationship.
A visual interface for model‐fitting

We describe a tool which supports the activity of a human being in fitting a mathematical model to measured or simulated data. The tool offers two principal advantages; its use requires a minimum of statistical knowledge, and its visual and interactive nature ensures that its use is intuitive. The tool is novel in that, in the iterative and often exploratory construction of a model, it represents graphically the benefit of all possible single changes to the existing model; a single selection action suffices to add a new term to a model or to remove it.

Geometric Brownian Motion, Option Pricing, and Simulation: Some Spreadsheet-Based Exercises in Financial Modeling

This paper presents some Excel-based simulation exercises that are suitable for use in financial modeling courses. Such exercises are based on a stochastic process of stock price movements, called geometric Brownian motion, that underlies the derivation of the Black-Scholes option pricing model. Guidance is provided in assigning appropriate values of the drift parameter in the stochastic process for such exercises. Some further simulation exercises are also suggested. As the analytical underpinning of the materials involved is provided, this paper is expected to be of interest also to instructors and students of investment courses.
Identification of hepatitis C virus genotypes and subtypes in patients from Maharashtra based on 5’UTR sequencing and analysis: a retrospective study

The clinical importance of HCV genotypes lies in its persistence and ability to cause chronic liver disease. Knowledge of HCV genotype distribution periodically is now essential for the clinical management of infected patients. The current study was designed to genotype and subtype HCV isolates in patients from Pune, Mumbai and Nashik districts of Maharashtra, determine association of HCV genotypes between both sexes and different age groups and perform phylogenetic analysis of the study isolates. Eighty HCV RNA positive patients were genotyped and subtyped in the study. Primers targeting 5’untranslated region (UTR) were designed for both amplification and sequencing of all isolates. All HCV isolates were characterized by direct sequencing of 5’ UTR followed by analysis with NCBI genotyping tool and in-silico BLAST analysis. The results were correlated with the Los Alamos Hepatitis C sequence and immunology database’s sequence alignment tool HCVAlign and phylogenetic analysis. Most of HCV isolates in this study belonged to genotype 3(56.25%) followed by genotype 1(35%) and genotype 4(7.5%). A rare genotype 5(1.25%) was identified in one of the patients. Prevalent subtypes were: subtype 3a (42.5%), subtype 1a (21.25%) and subtype 1b (13.75%). No notable association of age and gender with respect to genotypes was observed except for genotype 1a which showed an overrepresentation in males. Compared with phylogenetic analysis, NCBI genotyping tool was simpler for genotyping and subtyping HCV isolates. The present study revealed that HCV genotypes 3 and 1 were prevalent in Pune, Mumbai and Nashik districts of Maharashtra. With rare genotype (genotype 5) being identified and due to very few genotyping studies carried out in this region, this study aims at contributing towards monitoring the distribution of HCV genotypes among studied regions of Maharashtra.
A high-power harmonically self-mode-locked Nd:YVO4 1.34-μm laser with repetition rate up to 32.1 GHz

We develop a practical method to achieve harmonically self-mode-locked operation in a Nd:YV O4 1.34-μm laser for the generation of high-repetition-rate pulse trains. We exploit a gain medium with partial-reflection coating at the lasing wavelength to introduce effective mode selection. We numerically demonstrate that the coated gain medium can effectively modify the mode spacing of the laser cavity to be the harmonics of the free spectral range of the gain medium when the optical cavity length is adjusted to be commensurate with the optical length of the gain medium. We further employ a coated Nd:YV O4 crystal to realize harmonically mode-locked operation with a highest repetition rate of up to 32.1 GHz. At a pump power of 11.5 W, the average output power of 2.3 W is generated with a pulse duration as short as 5.7 ps. The locking range for the cavity length is also experimentally explored.
Trade and Poverty Case Study: Small Household Appliances

Abstract South Africa manufactures a diverse range of small household appliances. Increased international competition has forced a substantial restructuring of the domestic industry and existing suppliers have become leaner, more focused and much more profitable. Although the two market leaders continue to manufacture locally, the primary activity of both companies has switched from manufacturing to importing and brand management. The recent financial performance of these companies is impressive and their brand presence within South Africa remarkably strong. It would appear that South African manufacturers of small household appliances have adapted very well to the ‘threat' of international competition and have captured most of the gains. The gains to consumers, in terms of product variety and quality, have also been substantial; and the employment losses have been small. But input and output prices remain distorted by unnecessary tariffs and South African consumers continue to pay a high price for basic home appliances.
Histogram Equalization for Robust Speech Recognition

Optimal Automatic Speech Recognition takes place when the evaluation is done under circumstances identical to those in which the recognition system was trained. In the speech applications demanded in the actual real world this will almost never happen. There are several variability sources which produce mismatches between the training and test conditions. Depending on his physical or emotional state, a speaker will produce sounds with unwanted variations transmitting no acoustic relevant information. The phonetic context of the sounds produced will also introduce undesired variations. Inter-speaker variations must be added to those intra-speaker variations. They are related to the peculiarities of speakers’ vocal track, his gender, his socio-linguistic environment, etc. A third source of variability is constituted by the changes produced in the speaker’s environment and the characteristics of the channel used to communicate. The strategies used to eliminate the group of environmental sources of variation are called
Magnetic Susceptibility (V) Stratigraphy and Chemostratigraphy Applied to An Isolated Carbonate Platform Reef Complex; Llucmajor Platform, Mallorca

Inorganic whole rock geochemical and magnetic susceptibility (χ data have been gathered from seven sections through the Upper Miocene reef complexes of the Llucmajor Platform, Mallorca. The aim of acquiring these data is to determine what chronostratigraphic information a combination of magnetic susceptibility stratigraphy (MSS) and chemostratigraphy can provide in reef complexes of a carbonate platform with no nearby source of terrigenous material. Chi values display short-term cyclical fluctuations, maximum values commonly being associated with the upper bounding surfaces of sigmoids and sigmoid sets, the building blocks of the Llucmajor reef complexes. Values of ? are low at the bases of the sigmoids; they reach a maximum at the top of the sigmoids, and then fall rapidly to the base of the next sigmoid, indicating a base-level control on ? values. No longer term variation in the ? values have been identified that would enable differentiation of an old reef complex from one that is demonstrably younger in the cliff sections, and there is no apparent facies control on ? values. While the elemental data do not vary in response to base-level fluctuations and therefore do not define stratigraphic surfaces, they do show long-term variations, enabling reef complexes of differing ages to be geochemically characterized: the key to defining chemostratigraphic schemes. The elements used to characterize different age reef complexes are Cr, Zr, Al2O3, TiO2, Ga, and Rb, which are controlled by changes in the amount and composition of wind-blown terrigenous material and tuffaceous material. As such, the changes are chronostratigraphic events on the scale of the study intervals here. Although the two datasets used are both ultimately controlled by the mineral composition of the sediments, it has proved impossible to find a direct link between the elemental data and ? values. Despite the lack of an understanding of the relationship between whole rock geochemistry and ? values for this dataset, they clearly provide a means to (1) define stratal surfaces that relate to base-level fluctuation and (2) recognize reef complexes deposited at different times. Therefore, the combined approach adopted here for the Llucmajor reef complex has the potential to provide cross-facies chronostratigraphic correlations in detached platform carbonate settings, and since both methods can be applied to core and cuttings samples, the approach could work in subsurface settings where samples would be from well bores.
