This chapter provides an overview of contemporary theoretical perspectives in culture and communication scholarship, based on a review of articles published 2010-2014 in 5 well-known culture and communication journals. The analysis identified four characteristics of each article/abstract: meta/theoretical perspective (critical, interpretive, social science), research context (face to face, mediated etc), focus (intracultural, cross cultural, intercultural), and target cultural group (e.g., African-Americans, Asians, etc); as well as primary topic/s addressed. The review revealed a broad range of topics, foci and contexts. In addition, while the tripartite framework appears useful in understanding the range of current meta/ theoretical perspectives, there is a lack of interrogation of these Western approaches, as well as a lack of attention to economically, politically and geo-strategically less-powerful countries, resulting in “silent zones” in our theorizing. The chapter then calls for scholarship that really matter to contemporary humans as as nearly half of humans live on less than $2.50/day, there are more displaced people in the world than at any other time in human history, and ethnic and religious conflicts threaten the stability of vast world regions. Finally, specific research strategies are identified that may enhance our knowledge and more effectively apply this knowledge to critically important global communication challenges.
The present study makes an effort to understand the damage of earthen dams under static and seismic loading condition. To make the investigation more realistic, behaviour of earthen dams considering the occurrence of a phreatic line indicating the submerged zone due to seepage within the dam body is considered. In case of earthen dams, homogeneous or nonhomogeneous, the consideration of the occurrence of a phreatic line or seepage line through the dam body is an important part of the earthen dam design methodology. The impervious material properties in the submerged zone below the phreatic line due to seepage may differ a lot in magnitudes as compared to the value of the same materials lying above this line. Hence, to have the exact stress distribution scenarios within the earthen dam, the different material properties above and below the phreatic line are considered in this present study. The study is first carried out by two-dimensional as well as three-dimensional finite element analysis under static loading condition. The work is further extended to observe the effect of seepage due to the consideration of the phreatic line on dynamic characteristics of earthen dams. Free vibration analysis and seismic analysis based on the Complete Quadratic Combination (CQC) method by considering twodimensional and three-dimensional modeling are carried out to present the frequencies, mode shapes and the stress distribution pattern of the earthen dam.
