Bangladesh is a small low-mid-level country. Information and Communication Technologies are recognized as a powerful tool for socio-economic development. Nowadays technology confines this world into a small maze. Everything can be found in web. Yes, we are talking about online shopping; from land to dress everything can be sold or bought through online. So, online shopping become a trends in our busy corporate life and its impact has fallen in our country. This paper refers the challenges for the digital marketing of online shopping; or ecommerce or m-commerce. Also describe the present status of digital marketing and their impacts on the socio-economic development of the country. To sustain in today’s fast economy online shopping need excellent marketing mix to grow, introduce into consumers perception. Research will focus on as a bird eye view of constraints of marketing of this sector such as people’s perception, lack of efficient user, high price of electronics commodities.

Textbook costs have skyrocketed in recent years, putting them beyond the reach of many students, but there are options which can mitigate this problem. Open textbooks, an open educational resource, have proven capable of making textbooks affordable to students. There have been few educational development as promising as the development of open textbooks to lower costs for students. While the last five years have witnessed unparalleled interest and significant advances in the development and dissemination of open textbooks, one important aspect has, until now, remained unexplored: the praxis of learning analytics for extracting information regarding how learners interact and learn with open textbooks, which is crucial for their evaluation and iterative improvement process. Learning analytics off ers a faster and more objective means of data collection and processing than traditional counterparts, such as surveys and questionnaires, and—most importantly—with their capability to provide direct evidence of learning, they present the opportunity to enhance both learner performance and environment.

This paper examines the effects of real depreciation of the Argentine peso and changes in other relevant macroeconomic variables on real GDP in Argentina. The results show that real GDP is negatively influenced by real depreciation of the peso, the real interest rate and the expected inflation rate and positively affected by the ratio of government spending or government deficit to GDP, the real stock price, the real oil price and U.S. real GDP. Therefore, recent depreciation of the peso hurts real GDP whereas recent rise in the stock price helps real GDP. Relatively high interest rates reduce real GDP through personal consumption spending, investment spending and net exports.

Participatory on farm improved forage species evaluation was conducted at Keelewe Peasant association of Dassench Woreda of South Omo Zone in the 2014 under irrigated condition using the improved forage legumes to identify the adaptable and high biomass yielding forage species. The field experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications per tested species. The improved forage legume species tested in this study were Lablab purpureus, Lablab intoritum and Vigna unguiculatium. The dry matter yield obtained in this study revealed that there was none significance difference (p > 0.05) among the tested improved forage legume species in the study area. The dry matter yield production potential of tested species under irrigated condition in to the study area is 15.91, 14.16 and 15.40 t/ha for Lablab intoritum, Lablab purpureus and Vagigna ungulatium respectively. Out of the tested forge legume species over cropping season under irrigated condition, the one which gave the maximum dry matter yield was Lablab intoritum which gave (16 tones ha-1) and Vagigna ungulatium (15.40 tones ha-1) are advisable for the study areas. Therefore, it is imperative to evaluate the forage species for more seasons under similar condition and in addition to their feeding value under different intervention, chemical composition, their response to the disease and pest resistance, seed producing potential and dry matter production potential of species under supplementation different level of fertilizer rate.

The writing of history, as always, has been subject to biases, most of the time from those who call the shots, but sometimes from factors so insidious that it is very difficult to isolate them. Books of history written by approved authorities as well as by independent ones, are replete with such examples I do not have space for in this work. I need, however, to draw a line between deliberately sidestepped factors and those that, for one reason or another, have been omitted. My concern in this paper is to highlight the factors that, willingly or not, are overlooked by the author of the book under focus for what I think are ideologically motivated reasons. Pragmatists (Donald Davidson 2001b; 2004; Richard Rorty 1979;1982; Willard Van Quine 1969;1990) and language philosophers (Gontard 1981), indeed, speak of a cultural phenomenon, a driving force among intellectuals, constituted by popular ideas (opinions and thoughts or ethical norms) which, quite often act as doxatic1 factors that either favor alignment behind them or condemn dissident voices. It is, therefore, a major concern of this paper to show that Lawrence, the author has fallen victim of such a phenomenon by truncating chunks of vital historical information of the colonies she has studied, and more particularly the Moroccan one.

Logistics information system focuses on flow of information with storage and services of goods supply from the origin point to consumption point of organization. Logistics information system makes this flow more efficient with the help of cloud. Cloud computing manages the logistics information system centrally. The centralized data center keeps the track of information distribution which creates network congestion and overloading on data center when various requests of users from different regions occur at same time. So, the data center needs to be maintained effectively for better performance. This paper presents the distributed service broker policy to implement centralized data center and proposes distributed data center for logistics information system over cloud. This paper also presents the result of distributed service broker policy algorithm to reduce network congestion, higher latency and cost due to large number of demand of particular service in distributed data center for logistics.

The effect of impeller backward blades with slot on the centrifugal pump performance has been investigated numerically. Impeller blades have been modified with different geometrical parameters of slot such as: slot radial position (Rs), slot height (hs) and slot inclination angle (θs). 3-D numerical simulation has been carried out using commercial software, ANSYS® CFX, to study the effect on the pump performance at different flow rates. The numerical simulation has been compared with previously published experimental results to verify the numerical solution. In addition, the results have been compared with the impeller without slots for the same operating conditions. It has been shown that the slot parameters have a significant effect on the centrifugal impeller performance.

Adapting to effects of climate change and disaster risk reduction at present requires that the community at risk takes a leading role. This paper presents a theoretical under pinning of community based disaster risk reduction and management (CBDRRM). Ideally it is government’s responsibility to reduce vulnerability in communities. So far emergency response effort is the main approach being used. While the community has been perceived as the powerless recipient of support in times of a disaster. The community have the capacity, knowledge and skills of understanding their daily hazards they are exposed to but it is the influence support from outside the community that make them less willing to apply their local coping strategies to address disasters and hazards they are exposed to. The article presents a theoretical orientation for community based disaster risk reduction and management.

Collective memory requires a shared experience and the deposition of the experience in a manner that can be recalled at a later time. Collective memory can be transmitted orally, stored in writings, films, museums and other memorial sites, and also in our DNA. Recent studies have demonstrated that humans, like all animals, are themselves collectives, consisting of the host and abundant and diverse symbiotic microorganisms. The total DNA of a human, referred to as the human hologenome, consists of about 19,000 host genes and eight million microbial genes. It is now accepted that the microbial genetic information plays an important part in the fitness and evolution of animals and plants. We discuss here how the hologenome, especially the microbial component, interacts with cultural memory and contributes to collective memory. One of the novel points is that the microbial gene pool responds to changes in the environment on the basis of the principle of use and disuse. As such, the microbiome is particularly well-suited to serve as a vehicle for DNA-based collective memory.
