Atlantis: a time‐value model in e‐commerce

This paper presents a model for resolving two main issues of time in e‐commerce. The first issue is the time value of e‐commerce that represents the value of each moment of the commerce time from the perspective of buyers and sellers. Buyers and sellers can use this model to calculate the time value at each moment of time and accordingly decide whether it is profitable to buy or sell at that moment. The second issue is to allow buyers or sellers to increase their savings or decrease their costs by changing each of the factors governing the time value model of the concerned e‐commerce. We present relevant model specifically for Amazon e‐commerce to present a proof of concept of our proposed models.     

Adolescents’ Temperament and Character: A Longitudinal Study on Happiness

Personality is considered a major determinant of adults and adolescents Subjective Well-Being (SWB); mainly due to its relation to emotional reactivity, emotional intensity, and to the duration of emotional reactions. However, personality as presented above involves almost only differences in automatic emotional reactions and habits (i.e., temperament). Nevertheless, temperament together with learning experiences from different life events is responsible for what people make of themselves intentionally (i.e., character). The present study examines the relation between temperament and character to SWB at two points in time over a year in an adolescent sample (N?=?109). Adolescents reported personality (The Temperament and Character Inventory; TCI) and SWB at the beginning of the school year (T1). Subjective Well-Being was then again measured at the end of the school year (T2). Temperament (Harm Avoidance and Novelty Seeking) and character (Self-Directedness) predicted SWB at T1. However, only Self-Directedness predicted SWB at T2 and also small but significant changes in SWB at the end of the school year. The inclusion of character in SWB research is discussed.     

Analysis of Argumentation in the Discussion Sections of Published Articles in ESP Journal: A Diachronic Corpus-Based Approach

Argumentation has remained under-researched in studies analyzing academic journal publications despite its importance in academic writing. This paper reports a study in which we investigated stereotypical argumentative trends, lexico-grammatical features, and interactional metadiscourse markers in 354 research article free-standing discussion sections from the journal of ESP over forty years. The field of ESP was chosen because of its maturity, which has given substance to a dynamic ground for arguments. We drew on the pragma-dialectical approach to analyzing argumentations in the corpus. Findings indicated that due to the argumentative nature of the discussion section, certain argumentative trends recurred more often. The analysis of the lexico-grammatical features and metadiscourse markers of the standpoints also showed patterns of variability over time. The study concludes that it is imperative to incorporate relevant facets from various argumentation models to construct a comprehensive argumentation theory and gain deeper insights into argumentation in academic writing.
