The behaviour of an individual investor is expansively influenced by different biases that came into limelight in the rising regulation of behaviour finance. In finance, behavioural finance is the latest regulation that studies the cognitive psychology of the decisions that are taken by an individual related to money. The theory of standard economic had evolved this in its response and it has the ability to presume that people are sensible, prefers low risks investments and maximises their profits. In real time scenario it is seen that people are not that sensible when they make their decisions during the investment process. There are different behavioral biases factors that influence the investors while choosing their investment avenues. The objective of the study is to know the behavioural factors that affect the decision of the Investors and their impact on the investor in choosing the investment avenues. A sample of 273 respondents were taken in which Investors from different sector were surveyed with the help of standard questionnaire. Mean and t test was used to get appropriate results. It is found that there are different behavioral factors such as mood, emotional, heuristic, personality and overconfidence that influence the investors while making his investments and all the behavioural biases has a significant impact on the process of choosing the investment avenues.

The process of investment requires investors to take various types of decisions and the quality of those decisions determines the outcomes of the investment process. Standard finance theories and behavioural finance theories present different views on investment decision making based on the concept of rationality. Behavioural finance theories indicate that investors fail to perform in a completely rational manner when making investment decisions due to various biases. The objective of the study is to identify the behavioural finance based factors influence the investment decisions of household investors in the Northern Province of Sri Lanka. The necessary data for the study were collected from 1810 household investors in the Northern Province of Sri Lanka and the sample respondents were selected under Proportionate stratified random sampling method. The analytical tools of exploratory factor analysis and confirmatory factor analysis were used to analyze the data. The current study concluded that Representativeness bias, Overconfidence bias, Availability Bias, Loss Aversion bias, Regret Aversion bias and Herding influence the investment decisions of household investors.

Ο μεταβολισμός του σιδήρου δεν είναι επαρκώς μελετημένος στον σκελετικό ιστό σε αντίθεση με τον ηπατικό. Σκοπός της μελέτης είναι η σύγκριση της έκφρασης των γονιδίων του μεταβολισμού του σιδήρου στον ανθρώπινο σκελετικό και ηπατικό ιστό. Συλλέχτηκαν βιοψίες μυϊκού και ηπατικού ιστού από έξι φυσιολογικά άτομα. Επιλέχθηκαν να μελετηθούν12 γονίδια που εμπλέκονται στο μεταβολισμό του σιδήρου για την εισαγωγή σιδήρου στο κύτταρο, αποθήκευση και εξαγωγή του καθώς και δύο μόρια ρύθμισης της ομοιοστασίας του σιδήρου: εισαγωγή σιδήρου [οι υποδοχείς της τρανσφερρίνης (TfR1 και TfR2), το μόριο HFE, ο μεταφορέας δισθενών μετάλλων (DMT1,DMT1nonIRE), και το σιδεροφόρο μόριο λιποκαλίνη (NGAL)], αποθήκευση σιδήρου [η βαριά αλυσίδα της φερριτίνης (FTH1)] και εξαγωγή σιδήρου [η φερροπορτίνη (IREG1), η ηφαιστίνη (HEPH) και η σερουλοπλασμίνη (CP)] καθώς και δύο μόρια ρύθμισης της ομοιοστασίας του σιδήρου [η εψιδίνη (HAMP) και η αιμοτζουβελίνη (HJV)]. Ακολούθησαν αλυσιδωτές αντιδράσεις της πολυμεράσης, RT-PCR και ημιποσοτικοποίηση των επιπέδων έκφρασης των γονιδίων με τη μέθοδο της πυκνομετρίας (Densitometric Analysis). Τα αποτελέσματα εκφράζονται με βάση το ποσοστό επί τοις εκατό του γονιδίου της β-ακτίνης. Το γονίδιο της β-ακτίνης χρησιμοποιήθηκε για την κανονικοποίηση των επιπέδων έκφρασης, ως γονίδιο αναφοράς της μελέτης. Αναδεικνυόμενες διαφορές συγκριτικής έκφρασης μεγαλύτερες του 20%, των μελετημένων γονιδίων του μεταβολισμού του σιδήρου με ημιποσοτικοποίηση, αναλύθηκαν περαιτέρω με την μέθοδο της PCR σε αληθινό χρόνο (Real time PCR, qPCR) και ποσοτικοποιήθηκαν (LightCycler, Roche). Η στατιστική ανάλυση των αποτελεσμάτων ποσοτικοποίησης έγινε με το one paired t test και τα αποτελέσματα είναι στατιστικά σημαντικά (p<0,05). H συγκριτική μελέτη μεταξύ ανθρώπινου ηπατικού και σκελετικού ιστού στα επιλεγμένα 12 γονίδια έδειξε ότι: 1. Περισσότερα απο τα γονίδια: HJV, TFR1, HFE, DMT1, DMT1nonIRE, NGAL, HEPH, IREG1 ,DMT1(IRE) , DMT1nonIRE, FTH1 εκφράζονται και στους δύο ιστούς με ποσοστό έκφρασης >70% των επιπέδων έκφρασης της βακτίνης. 2. Εξαίρεση αποτελούν τα HAMP, CP και TfR2 που απουσιάζουν ή παρουσιάζουν ελάχιστη έκφραση (<10% των επιπέδων έκφρασης της βακτίνης) στο σκελετικό μυ αντίστοιχα. 3. Ενώ τα HJV και HEPH παρουσιάζουν μεγαλύτερη έκφραση των επιπέδων mRNA στο σκελετικό μύ συγκριτικά με το ήπαρ (SM/L=2,65±1,1(p<0,05) και SM/L=1,5±0,06(p<0,05 αντίστοιχα στην Q-PCR). (Εικόνα 1). Η εργασία αυτή αφορά φυσιολογικές καταστάσεις ανθρώπινων ιστών, δίνει όμως σημαντικά ερεθίσματα για αντίστοιχες μελέτες του μεταβολισμού του σιδήρου σε παθολογικές καταστάσεις. Υπογραμμίζει δε την σπουδαιότητα του σκελετικού μυϊκού ιστού και την ανάλογη συμμετοχή του στη ομοιοστασία του σιδήρου. Οι ποσοτικές διαφορές που παρατηρούνται στην έκφραση γονιδίων που εμπλέκονται σε διάφορα κυτταρικά μονοπάτια αναδεικνύουν την ανάγκη περαιτέρω έρευνας του κυτταρικού μεταβολισμού στο σκελετικό ιστό.

This mixed-methods research study shows that the incorporation of real-time polling in an introductory Anthropology course (n = 107) taught in a large lecture class at a mid-size university can have a positive impact on students' perceptions of (1) satisfaction; (2) participation; and (3) whether the instructor was able to use the polling results effectively to gauge students' understanding. Independent sample t-test and ANOVA results indicated gender, race, and extroversion level were shown to have significant impacts on participation and understanding. Students did not show a significant preference for either of the two real-time polling systems (TopHat or TurningPoint) used in this study. This study shows how the incorporation of real-time polling in large, introductory, lecture classes can have a positive impact on students and has the potential to decrease the attrition rates and to improve student learning enrolled in these classes.

This paper seeks to analyse how behavioural factors influence the financial decisions of young Mozambican investors. The standard theory of finance assumes investors make rational financial decisions, seeking to minimise risk and maximise their expected utility. However, several studies have been conducted criticizing the assumption that investors are rational, opening the way to behavioural finance theory. According to the behavioural finance approach, financial decisions made by individuals are not based on rational thinking and their risk taking behaviour depends on their beliefs or feelings. Our analysis reveals that young Mozambicans are risk averse towards certain gains and risk lovers when faced with certain losses; they are excessively optimistic about the future; they use the information available as an anchor for their estimates; and they are so overconfident that they believe estimates in uncertain situations to be more accurate than they really are.

This study examines possible parallels between large-scale organization in music and discourse structure. Two experiments examine the psychological reality of topics in the first movements of W. A. Mozart's String Quintet No. 3 in C major, K. 515, and L. van Beethoven's String Quartet No. 15 in A minor, Op. 132. Listeners made real-time judgments on three continuous scales: memorability, openness, and amount of emotion. All three kinds of judgments could be accounted for by the topics identified in these pieces by Agawu (1991) independently of the listeners' musical training. The results showed hierarchies of topics. However, these differed for the three tasks and for the two pieces. The topics in the Mozart piece appear to function as a way of establishing the musical form, whereas the topics in the Beethoven piece are more strongly associated with emotional content.
