The value of the parameter p reflects whether SGC effect exists and the size of SGC effect. Under certain condition, when p = 0. 002, electromagnetically induced transparency occurs; when p≠0. 002, lasing without inversion can be realized;when p = 0.95, high index of the refraction with zero absorption can be obtained.展开更多

We show that the significantlyenhanced conversion efficiency enabled by ultraslow propagation of pump waves has no directrelationship with the single-photon detuning, which is different from the FWM with a single EIT. Themost important feature is that our scheme is also capable of inhibiting and delaying the onset ofthe detrimental three-photon destructive interference that looks like a recent scheme [Phys. Rev.Lett. 91 (2003) 243902] and may be used for generating short-wave-length coherent radiation.展开更多

Hence, the creation of transparency in the production process has been the focus of recent legislation. In addition to tracking and tracing, one finds in the public discussion an increasing number of demands for further information on such issues as food safety, animal and environmental protection and the sustainability of food production processes. However, it has not yet been sufficiently clarified which information about the production process--and thus which level of transparency--is actually desired or can actually be processed by consumers at the point of sale. In order to analyze this topic from the viewpoint of consumers, a large-scale empirical study has been conducted. This research uses an adaptive conjoint analysis to determine what transparency expectations consumers have with regards to information on packaged pork. Initial results show a very heterogeneous demand for information. Furthermore, consumers' demand for more information sometimes does not match their actual benefit profiles. The results provide insight into consumers' information needs and their willingness to pay for greater transparency; they also have interesting implications for meat processors' product development strategies.展开更多

The subject is constituted in enunciation, and its polysemic discourse clashes with the transparency of meaning. According to Pêcheux (1988), the contradictions in discourse simultaneously establish regularity and instability of meanings, leading it to misunderstanding, to the event. Photography destabilizes that which is already formulated and brings out that which is new, the unexpected meaning, the decisive moment. We analyze this process in the picture by Sebastiao Salgado---"The cradle of inequality lies in the inequality of the cradle". (CAPES-BEX 4394/10-0, FAPESP 09/54417-4, CNPq.)展开更多

I maintain that becoming fully a person and respecting others as persons are achievements that are not assured for all of us. Thus, for the purpose I prepare the ground for an account of good life that rests on valuational consciousness. I propose that one may ascribe valuational consciousness to a person who is a value-sensitive rational being striving to attain a kind of inner transparency. Evidently, to say that a person has valuational consciousness is to stress the values, which are built into personal consciousness. The life of a person, whether that of truth, courage, nobility, justice, kindness, is a life marked by ego transcending personal consciousness that reaches out to humanity at large. And such a repository of values enables a human being to attain the ideal of good life. The ideal of good life, I contend, consists of attaining the higher order posture of selflessness--a posture of inner transparency. It is to shake off the egocentric partiality that characterizes our usual attitudinal stance towards one another.展开更多

Employability skills need to be checked rather than unemployment problem in India. The paper further aims to explore the necessary skills to the challenges of globalizing trends. The issues, approaches, and remedial strategies are focused with reference to the people's skills. As the reflections of quality and competence depend on transparency and accountability of the organization, it is necessary to improve the required skills which enhance the levels of confidence. The potential employer's requirements are need to be worked very keenly by the institutions. The paper also deals with the effective learning process, which is at par with global counter parts. Exposure to the universal student-centered learning is emphasized to enhance the very crucial pace of work place. Finally this paper studies effective micro and macro issues regarding the dynamics of the industry by applying a broad range of employability skills complementing the technical skills.展开更多

By investigating the banking sectors of four Asian countries/regions including China, Hong Kong, the Philippines, and Singapore which have adopted International Financial Reporting Standards (IFRS), this paper finds that after the application of FVA, the estimated cost of equity of the sampled banks significantly decreases and the relationship between banks' loan loss provisions (LLP) and earnings before provisions and tax (EBPT) becomes irrelevant. The evidence supports the effects of FVA adoption on the enhancement of accounting quality. In addition, sound legal/extra-legal systems are closely linked to the degree of accounting quality and still have a strong influence on FVA.展开更多

Initial signs suggest that Emirati as well as Egyptian media have drawn some first findings from the upheavals of the "Arab Spring", so that the first flimsy form of media accountability and a new openness is to be found in the media orient. Moreover, this study tries to draw some parallels between the "old" Arab sphere (Egypt) and the "new" Arab world (UAE) in order to generate new knowledge exploratively. Twelve journalists and media professionals from both countries have been qualitatively interviewed between November 2011 and May 2012 in this regard at spot and via phone or skype. This study distinguishes between two different media systems within the Arab sphere. International comparative studies on the media systems within the heterogeneous world of Arabia are considered as a desideratum in the field of journalistic research.展开更多

Data for corporate transparency are collected from annual reports for the years 2005-2007. Corporate transparency is indexed by the amount of information disclosed in company's annual report. The disclosure index reporting model developed in the current research is based on the Annual Report Award (ARA, an award given annually to Indonesian listed and non-listed companies), and firm performance is measured using two indicators: ROA (return on assets) and Tobin-Q. The political influence variable is proxied by two indicators: government ownership and the existence of politicians in Board of Directors (BOD). Results demonstrate that contrary to the hypothesis, government ownership (political influence) has positive relation to corporate transparency, as well as to ROA (firm performance). Results also support the hypothesis that transparency act as a mediating variable for the relationship between political influence and firm performance. However, when political influence is pmxied by existence of politicians in BOD and fm'n performance proxied by Tobin-Q, data seems to give support to the hypotheses proposed. The discussion and implications of the findings and suggestions for future research arc discussed.展开更多

In the period of 2007-2010, audit firms overcame the barrier and started disclosing the data on their operations, being treated as confidential for a long period of time. A continuous period of four years might seem to be a short period to create a big picture of the developments in the audit profession in the Republic of Macedonia. However, the issue of who, how, and for what purposes these data were used remains open. Pursuant to Article 7 of the Statute of the Institute for Certified Auditors of the Republic of Macedonia (ICARM), the institute is in charge of carrying out quality control. In 2010, ICARM carried out, for the first time, quality control over the operations of audit firms in 2009. Did ICARM use and how much did it use the data from the transparency reports in the process of selecting the entities to be subjected to quality control? Is it possible to establish relation between transparency in the operations of the audit firms and improvement of quality of services they offer to their clients? The authors will try to provide the answers to the abovementioned questions in this paper.展开更多

Public institutions tend to make available to the public, more data and information concerning the administration, the manner of use of public goods and resources. At the same time, each institution is called upon to deal with the demand of transparency and participation by citizens who increasingly use Internet 2.0 and social media. After a reflection on how public administrations acted in the phase of Web 1.0 to practice transparency and accountability in terms of communication, this paper considers the elements of continuity and the new opportunities linked to the advent of Web 2.0 and open data. At the end of this analysis, the focus is on the strengths and weaknesses of this process, with a particular attention to the role of the public communication.展开更多
