To serve and protect: Textualizing the Falklands conflict

ABSTRACT

This article examines the roles and functions of narratives in the conduct and prosecution of the Falklands War. It looks at how, and with what degree of success the Falklands conflict was emplotted into potent definitions of national identity; how it was constructed as the embodiment of certain cherished ideals of nationhood, and thus slotted into what Patrick Wright calls the ‘mythical Histories’ of Britain and Argentina. It considers how the languages of diplomacy and sport were articulated within a discourse of war. It examines how participants in the conflict, journalists and combatants, made use of narratives cognate with the tradition of the romance quest in an effort to make sense of the conflict, promote its aims and provide themselves with reassurance at times of uncertainty, if not naked terror. It also considers how opposition to the war, dissenting opinions about the legitimacy of its aims and prosecution, and a more critical view of its costs, was most often and most effectively articulated in narratives which contested and deconstructed the discursive norms of the romance quest, or which challenged the coherence of the narrative or the narrative subject itself.

Usability analysis of 2D graphics software for designing technical clothing

With the advent of technology, the computer became a working tool increasingly present in companies. Its purpose is to increase production and reduce the inherent errors in manual production. The aim of this study was to analyze the usability of 2D graphics software in creating clothing designs by a professional during his work. The movements of the mouse, keyboard and graphical tools were monitored in real time by software Camtasia 7? installed on the user's computer. To register the use of mouse and keyboard we used auxiliary software called MouseMeter?, which quantifies the number of times they pressed the right, middle and left mouse's buttons, the keyboard and also the distance traveled in meters by the cursor on the screen. Data was collected in periods of 15 minutes, 1 hour and 8 hours, consecutively. The results showed that the job is considered repetitive and high demands physical efforts, which can lead to the appearance of repetitive strain injuries. Thus, the goal of minimizing operator efforts and thereby enhance the usability of the examined tool, becomes imperative to replace the mouse by a device called tablet, which also offers an electronic pen and a drawing platform for design development.

Organizing evaluation to serve the needs of program planners and managers

Evaluation is often both conceptually and functionally separate from program planning and operations management. Though program managers may not see themselves as served well by the work of evaluation staffs, there are a number of potentially beneficial side effects to be realized from close collaboration between program administrators and evaluators. These flow only when the evaluation task is broadly defined and when both administrators and evaluators recognize their interdependence. Particular functional benefits to management from evaluation are described. Characteristics of interorganizational relations which might increase the probability of their attainment are then outlined and discussed.     

A novel approach for evaluating programs designed to serve military veterans: Using an adapted common components analysis

Evaluators are challenged to keep pace with the vast array of Veteran support programs operating in the United States, resulting in a situation in which many programs lack any evidence of impact. Due to this lack of evidence, there is no efficient way to suggest which programs are most effective in helping Veterans in need of support. One potential solution to this dilemma is to reconceptualize program evaluation, by moving away from evaluating programs individually to evaluating what is common across programs. The Common Components Analysis (CCA) is one such technique that aggregates findings from programs that have undergone rigorous evaluation at the level of program components (e.g., content, process, barrier reduction). Given that many Veteran programs lack outcome evidence from rigorous studies, an adaptation to CCA is needed. This report examines cross-sectional data from a pilot study using an adapted CCA across five domains of well-being (i.e., employment, education, legal/financial/housing, mental/physical health, and social/personal relationships). The purpose of this preliminary study is to determine the feasibility of eliciting program nominations and program components from Veterans via an online survey. When coupled with a longitudinal research design, this adaptation to CCA will allow for stronger causal claims about the expected impact of different program components within and across a variety of domains.
