Dividend Policy and Its Impact on Stock Price – A Study on Commercial Banks Listed in Dhaka Stock Exchange
Authors: Al Masum Abdullah 
Published: March 2020

How do dividend policy decisions affect a firm’s stock price, is a widely researched topic in the field of investments and finance but still it remains a mystery that whether dividend policy affects the stock prices or not. There are those who suggest that dividend policy is irrelevant because they argue a firm’s value should be determine by the basic earning power and business risk of the firm, in which case value depends only on the income (cash) produced, not on how the income is split between dividends and retained earnings and opponents of this statement called dividend is irrelevance, that investors care only about the total returns they receive, not whether they receive those returns in the form of dividends, capital gains or both.The results of researches conducted in various stock markets are different. There are many internal and external factors, which simultaneously affect stock prices and it is almost impossible to segregate the effect of each so the variations remain. This paper empirically estimates excess stock market returns for all the thirty banks listed in Dhaka Stock Exchange for the period of 2007 to 2011. Attempts are made to examine, what kind of relationship exists between dividend policy and stock market returns of private commercial banks in Bangladesh, and to what degree the returns on stocks can be explained by their respective dividend policy for the same period of time. Various theories related to dividend policy are tested in various parts of the world with different results and findings. Various other articles are reviewed, written in Bangladesh and abroad to see the significance of dividend policy on the stock prices and to compare the results of this research with those conducted earlier. Sample size is large i.e. all the listed commercial banks of Dhaka Stock Exchange so the results are reliable and valid. Panel data approach is used to explain the relationship between dividends and stock prices after controlling the variables like Earnings per Share, Return on Equity, Retention Ratio have positive relation with Stock Prices and significantly explain the variations in the market prices of shares, while the Dividend Yield and Profit after Tax has negative, insignificant relation with stock prices. Overall results of this study indicate that Dividend Policy has significant positive effect on Stock Prices.

Enhancing Food Security Through Innovation Platforms: Experiences from Research into Use Project in Rwanda
Authors: Dusengemungu L. , Kibwika P. , Kiazze FB 
Published: March 2020

Maize is an important food security crop in Rwanda and the East African region, however the maize value chain is not well developed and the productivity is still low partly because of low technology uptake by the smallholder farmers. Since 2006, the Department for International Development (DFID) supported the “Research Into Use” (RIU) programme in Rwanda to enhance the uptake of agricultural technologies using innovation platforms (IPs). Maize was one of the target crops for intensification particularly in Nyagatare District for which an IP was established. The purpose of the innovation platforms was to faciliate interaction of the key actors in the value chain including farmers, cooperatives, inputs suppliers, processors, traders, credits providers, local leaders, research and extension to establish mutual relationships for value chain development. This study assessed processes of establishing IPs and requirements for their effective operations and sustainability. Data were collected using focus group discussions, observations and interviews. SPSS and SNA softwares were used to analyze data. Through actor interactions in IPs, farmers` problems were prioritized by research; relationships were established between research institutions, NGOs, processors and finance institutions for value addition of maize thereby creating a pull effect for increased production and income. Increased production, productivity and incomes are core to food security. The IP was a mechanism for developing value chains that provided incentives and means for access to and adoption of technologies for increasing productivity of maize. Hower, functional IPs requires facilitation and capacity building of the actors to interact in a mutually beneficial manner.

On-line Shopping Trends, Patterns and Preferences of University Undergraduate Students: A Survey Study on Sylhet Region
Authors: Rahaman Md. Mahbubur 
Published: March 2020

With the explosion of the e-commerce in the past decade, different buying patterns and preferences have emerged for customer groups and other demographics. These patterns have been measured and collected by numerous independent marketing, business and even academic studies to understand how consumers connect with the new adventure of e-commerce. As the internet and online shopping is growing at a very fast pace worldwide, investigating this trend within Bangladeshi context is crucial considering that it is a relatively new trend in the country, the result is a lack of literature. This paper consists of the groundwork with a brief introduction of recent trends in e-commerce on people of Bangladesh; particularly its impact on university undergraduate students in Sylhet region. This has been followed by their general perceptions and preferences of the online shopping including products and website selection. Each of these e-commerce “characteristic” is compared to information combined from survey questions and open-ended discussions with a small sample group of university students at undergraduate level in Sylhet region. It also investigates into positive as well as negative website characteristics and sum up the favorable elements into a description of an e-commerce website that would suitable to the group being studied. Findings have been presented by means of the formation identified during the data analysis, indicated that an increasing number of the students at undergraduate level are now using the internet for purchase. It also observed that between male and female students, male students are purchasing products online more than female students. Although student’s participation is increasing, there are some limitations for what the potential numbers of students are not able to purchase via online.

Une larme de cognac et un soupçon de lait – à propos de quelques quantifieurs nominaux marquant une petite quantité
Authors: Izert Małgorzata 
Published: March 2020

Dans cet article nous analysons des collocations qui constituent la suite DET N1 de N2 et servent à exprimer habituellement une (très) petite quantité ou une quantité minime de liquide. Les paraphrases de ce type de collocations données par les dictionnaires de langue comme ‘petite quantité de N’, ‘un peu de N’ ne renvoient qu’à une partie du sens apporté par ces quantifieurs nominaux dont le sens exact est beaucoup plus complexe et nuancé. Par exemple, une pointe de whisky indique non seulement une petite quantité d’alcool mais désigne aussi une intensité faible de son goût. De même, la combinatoire de ces collocatifs attestée par les dictionnaires de langue n’est pas aussi large que celle confirmée par l’usage écrit récent dans les textes provenant des données numérisées. Ces données permettent de distinguer quelques types de N2 d’après la nature des objets de référence qu’ils désignent (cf. toutes sortes de boissons (y compris les alcools) ou toutes sortes de produits liquides mais aussi les produits massifs alimentaires ou non alimentaires et les idées abstraites – sentiments, émotions, etc. et même, ce qui peut paraître surprenant, les styles musicaux).
A New Hegemonic Hope: Daemonic Agency in the Techno-Thriller Novels of Daniel Suarez
Authors: Giguère Christian 
Published: March 2020

The article reflects on how contemporary science fiction has initiated a paradigmatic shift in the conceptualization of hegemonic force. Focussing on the figure of the Daemon depicted in two recent techno-thriller novels – Daemon (2009) et Freedom (2010) by American author Daniel Suarez – I show how the pervasive conceptions surrounding the agency of modern technology that we find in the late writings of Martin Heidegger are confronted in twenty-first century narratives that question the way we conceptualize the hegemonic directing of human consciousness by re-examining the figures of Ancient Greco-Roman thought. In the article, I pay particular attention to how what I call the “daemonic mobility” of human thought that we find in the writings of the Neo-Platonist Apuleius is eliminated by Augustine in his devising (in City of God and his other writings) of a permanent locus of existential consciousness, and how this contributes to Heidegger’s understanding of the essence of technology as the “coming to presence of art”. By re-investing the figure of the daemon and the mobility of human thought, Suarez narratives allow us to renew our understanding of the nature of this poeisis.
Dismembering the Cautionary Cliché: Re-Reading the Techno-Science Ethics in Mary Shelley’s Frankenstein
Authors: Hageman Andrew C 
Published: March 2020

In a wide range of academic, public, and governmental policy discourses, Frankenstein continues to appear today with an uncanny persistence. Many of these appearances, however, have taken on identities not recognizably connected to Mary Shelley’s 1818 novel. Instead, the word “Frankenstein” has been transformed into a cultural signifier of theological and/or technological cautionary tales about limits to and transgressions of human techno-scientific endeavors. This essay presents methodical close readings of the 1818 and 1831 prefaces to the novel as well as key passages within the novel to argue that Shelley's writing does not support the cautionary uses to which her novel is put today. The essay further argues that only by re-animating the horror present in the dun white sockets of this monumental novel that the cautionary cliché has obfuscated can we work through the trauma that drives us obsessively to repeat this story while consistently avoiding the anxieties and imaginations that constitute our techno-scientific trauma.
‘You Know the Business and I Know the Chemistry’: The Scientific Ethos of Breaking Bad
Authors: Wetherbee Ben , Weaver Stephanie 
Published: March 2020

We conduct an analysis of the American television drama Breaking Bad as a show that resists the label of 'science fiction', while its use of scientific imagery and discourse create what we call a 'scientific ethos'. This essay explores the use of science as an appeal to intelligence and credibility in Breaking Bad. We include a theoretical discussion of how ethos emerges in serial television narratives, an analysis of the show's textual construction of its ethos, and a discussion of the intertexual and social effects of that ethos. Finally, we recommend the adoption of a rhetorical perspective in analysing how images of science circulate in fictional texts.
Inputs and Outputs: Engagement in digital media from the maker's perspective
Authors: Witchel Dr. Harry J , Westling Carina E I 
Published: March 2020

In the process of developing a technology assembly that can objectively measure engagement on a moment-by-moment basis, subjective responses to stimuli must be shown to correlate with the component technologies, such as motion capture or psychophysiology. Subjective scales for engagement are not all consistent in segregating the measurement of causes (inputs to the audience) and effects (outputs from the audience); this lack of separation can obscure appropriate inferences in the relationship between cause and effect. Inputs to the audience are scripted, and are controllable by the maker. An output is what the designed experience engenders in the end-user, and outputs can include both mental states (satisfaction) and physical activities (heart rate) during the stimulus and subsequently. Inputs can be maximised by design, whereas to optimise outputs from the end-user, one needs an empirical process because outputs are dependent upon an interpretive process or entry into a biological system. Outputs will be highly dependent on audience and context, and they will often be quite variable, even in individuals from a similar audience profile. It is critical that, in instruments assessing the relationship between inputs and outputs, controllable inputs to the end-user must not be conflated with outputs engendered in the end-user.
Dirty History and America's White Trash: American Eugenics and the Problem of Purity
Authors: Currell Sue 
Published: March 2020

Sue Currell’s paper discussed the idea of purity on several levels of discourse: firstly, as a historical trope by which both “welfare” and eugenics were promoted as progress, seen in the metaphorical ideas of welfare as “social house cleaning” or the pure and thereby efficient body during the 1930s. Secondly, how “pure” records such as well-intentioned documentary photographs aiming to uplift the rural poor were “infected” with the “fictions” of eugenic discourse around gene impurity. Finally, how researching the history of eugenics raises further trouble by hanging out the “dirty laundry” of the process of history making itself, in raising the problematic of historical knowledge and pure truths/transparent meanings, arguing that the methodological issues raised by researching eugenics highlight mostly an “impure”, tainted, or incomplete historical record that needs acknowledgment.
Rape, Possession and the Law in Thomas Middleton's 'Women Beware Women' and 'The Changeling'
Authors: Piraino Annaliese Beth 
Published: March 2020

Patriarchal constructsordain male dominance over female lifestyle and livelihood, additionallydetermining feminine value: more specifically what should happen with, and to, awoman's body. Outlined within Renaissanceproductions such as Thomas Middleton’s WomenBeware Women and The Changeling, possessiveinequality lies behind each woman taken by her rapist. Early laws such as the 1275 Statute of Westminster liken rape to theft and help fashionthe practice to be resultant of female Edenic flaw. Thus, both culture and law reveal the trivializationof rape through the necessity of possession. Rape and other sexual inequities become justifiable as a requisite rightof the man, and part of the natural order to satisfy the woman. Throughout culture and law, rape and chastity expectations demonstratethe need for men to “purify” male dominated societies of women that "drivemen" to sexual compulsion. Women arerepresentative of societal atrocities--manifestations of patriarchal fearspertaining to the loss of power. Purgingsociety of supposed forces proves a valuable service to patriarchal order, as aloss of these controls over the woman could prove disastrous. Thus, in order for the familial and societalpatriarchy to maintain stability, it is the right of the man to exercise his jurisdiction. Because women are possessions, theirviolation directly relates back to their possessors; therefore, the woman’snatural propensity to be ravished, elicits a man’s cultural predisposition topossess. Ultimately, these texts expose possession as the factor used to justify man’s desire to rape, and denote the woman’s fault in her own rape. The act of rape is a political means of advancement in a culture filled with women in need of being ruled. Thus, patriarchal construct requires rule over sexuality, which must be regulated to protect women, the men that possess them, and the patriarchal society as a whole.
Putrefaction and Purity: Death and Denial in Andrew Miller’s Pure
Authors: Downes Rebecca 
Published: March 2020

The great carapace of human culture is erected to deny our essential corporeality, our persistent vulnerability, and our inevitable extinction; death is quite simply an elephant in the room of Western culture. Inspired by Phillipe Ariès’s The Hour of Our Death, Andrew Miller’s 2011 novel, Pure, is a fictionalised account of the clearing of Les Innocents cemetery in Paris in 1785. True to Foucault’s conception of history as a means of interrogating the present, Miller’s novel investigates the origins of contemporary attitudes to death in Enlightenment values of reason, sanitation and medicalization. This rationalisation coupled with, and complicated by, the Romantic revolution in sentiment that dates back to the late eighteenth century and still reverberates throughout Western society today has led to a collective denial of death and a denunciation of the decaying and diseased body. The book’s title, Pure, refers to this purification of culture through the purgation of death, but it also brings to mind Kant’s Critique of Pure Reason, which is contemporaneous with the novel’s setting. This paper will argue that Miller’s novel is itself a critique of the kind of abstract thinking or pure reason that serves to deny the body and banish death. Miller’s sensuous, voluptuous prose brings death to life, so to speak, literally and metaphorically depicting the resurgence of the dead body and resituating death within daily life. A contemporary ars moriendi, Pure exemplifies the praxis of storytelling as a form of embodied knowledge that transcends abstract theory and situates discourse in the arena of shared sentience and shared mortality.
