Arabic texts analysis for topic modeling evaluation     

Abderrezak Brahmi  Ahmed Ech-Cherif  Abdelkader Benyettou 《Information Retrieval》2012,15(1):33-53

Significant progress has been made in information retrieval covering text semantic indexing and multilingual analysis. However, developments in Arabic information retrieval did not follow the extraordinary growth of Arabic usage in the Web during the ten last years. In the tasks relating to semantic analysis, it is preferable to directly deal with texts in their original language. Studies on topic models, which provide a good way to automatically deal with semantic embedded in texts, are not complete enough to assess the effectiveness of the approach on Arabic texts. This paper investigates several text stemming methods for Arabic topic modeling. A new lemma-based stemmer is described and applied to newspaper articles. The Latent Dirichlet Allocation model is used to extract latent topics from three Arabic real-world corpora. For supervised classification in the topics space, experiments show an improvement when comparing to classification in the full words space or with root-based stemming approach. In addition, topic modeling with lemma-based stemming allows us to discover interesting subjects in the press articles published during the 2007–2009 period.  相似文献   

Existence of solutions for nonlinear fractional q-difference integral equations with two fractional orders and nonlocal four-point boundary conditions     

Bashir Ahmad  Juan J. Nieto  Ahmed Alsaedi  Hana Al-Hutami 《Journal of The Franklin Institute》2014

We investigate the existence of solutions for a nonlinear fractional q-difference integral equation (q-variant of the Langevin equation) with two different fractional orders and nonlocal four-point boundary conditions. Our results are based on some classical fixed point theorems. An illustrative example is also presented.  相似文献   

360 degree feedback: an integrative framework for learning and assessment     

Ding Ding Tee  Pervaiz K. Ahmed 《Teaching in Higher Education》2013,18(6):579-591

Feedback is widely acknowledged as the crux of a learning process. Multiplicities of research studies have been advanced to address the common cri de coeur of teachers and students for a constructive and effective feedback mechanism in the current higher educational settings. Nevertheless, existing pedagogical approaches in feedback are fragmented and ad hoc in nature. Taken in isolation, each approach fails to capture the full role and complexity of assessment feedback in the learning process. The paper provides a synthesis of existing practices in the field of assessment feedback and identifies the core guiding elements to develop a holistic and integrated feedback system. The 360 degree (360°) feedback system is proposed and its systematic implementation is demonstrated via the interplay between self-, peer and teacher assessment. It is concluded that the elements of 360° system when combined and integrated help to maximise the functions of feedback to enhance learning.  相似文献   

Governing public universities in Arab countries     

Ahmed A. ElObeidy 《Perspectives: Policy and Practice in Higher Education》2013,17(4):131-137

Traditionally in Arab public universities, presidents are appointed by government authorities. Recently, in uprising Arab countries universities' presidents have been elected by universities' faculty members. Neither traditional nor self-governance pattern succeeded to modernise Arab universities. Reforming patterns of governance is critical for improved productivity and accountability in Arab universities. Applying the modern pattern of university governance depends on the country's political system and extent of democracy. Arab countries need to establish an improved process of searching for leadership candidates. Improving patterns of universities' governance in Arab countries can lead to improving higher education and research and enhancing competitiveness among faculty members.  相似文献   

Interface of Political Opportunism and Islamic Extremism in Bangladesh: Rhetorical Identification in Government Response     

Rukhsana Ahmed 《Communication Studies》2013,64(1):82-96

Critical approaches to study Bangladesh's political development have been widespread, especially in the fields of political science and international relations. What is missing from the existing critical account is an examination of the language that Bangladesh's political leaders use as symbolic means. This paper will critically analyze a rhetorical event, Address to the Nation by Begum Khaleda Zia, former Prime Minister of the People's Republic of Bangladesh, at the Fourth Anniversary of the former Alliance Government at Dhaka, Bangladesh on October 10, 2005 Zia , B. K. ( 2005, October, 10 ). [Address to the Nation]. Speech presented at the Fourth Anniversary of the Alliance Government. Ministry of Foreign Affairs. Government of the People's Republic of Bangladesh. Retrieved January 6, 2006, from http://www.mofa.gov.bd/st_prime_minister.htm  [Google Scholar]. The purpose is to investigate the responses of the then Bangladesh government to growing Islamic militancy in the country. Kenneth Burke's concept of identification will be used to this end.  相似文献   

Exploring Licensing Translation Rights in the Arab World     

Ahmed Rashad 《Publishing Research Quarterly》2013,29(4):383-390

Gathering information about publishing industry in the Arab world is one of the main important challenges for either Arab publishers to develop there business or for foreign (scouts, agent, publishers and printers) to make business there. In this paper I tried to present a practical point of view of an Arab publisher who went deep in this business through the past year.  相似文献   

Peer Support in Negotiating Multiple Relationships within Supervision Among Counselor Education Doctoral Students     

Amanda J. Minor  Asher Pimpleton  Tracy Stinchfield  Heath Stevens  Nor Asma Othman 《International journal for the advancement of counseling》2013,35(1):33-45

Counselor education doctoral students (CEDSs), like other doctoral students, need assistance and support to ensure their self-care. One area markedly affecting self-care is one’s relationships with others. The purpose of this article is to examine the multiple relationships involved within CEDSs supervision, the potential areas to utilize peer support, and to propose peer support as an intervention for CEDSs. The authors discuss implications for using peer support to negotiate issues such as multiple relationships while being a CEDS and propose a call for research into the use of peer support as an effective approach to managing multiple relationships.  相似文献

The politics of fear in the making of worlds     

Sara Ahmed 《International journal of qualitative studies in education》2013,26(3):377-398

This paper revisits "the Menchú controversy" by examining the relationship between "truth", politics and fear in the "making of the worlds." The author argue that "Menchú controversy" can teach us a lot about how "truth" involves a politics of containment whereby "others" are contained by the judgment that they have failed the truth at the very moment that they challenge how some "truths" are given or become givens. Such judgments are not simply about reading the testimonios of others as "perjured", but also work to construct others as fearsome and threatening, such that the defence of truth becomes "a matter of life and death." To explore the role of fear in containing others, the author offers a reading of the Menchú controversy alongside the reception given to Sunera Thobani's speech in which she criticizes the United States' "war on terrorism." She shows how Thobani's speech is constructed as an act of terror because it calls into question the very "truths" that have justified the war, by showing that they rely on an ontological distinction between legitimate and illegitimate violence. The paper relates both the Menchú and Thobani cases to broader discourses of fear and anxiety that have circulated since September 11 2001 and argues that fear works to secure "truths" precisely through the narration of crisis or insecurity. Rather than considering fear as coming from within a subject, or as a characteristic of an object, the author suggests that fear works to effect the very boundaries between subjects and others, partly through the feeling that such boundaries have already been threatened by the presence of others. She also shows how fear operates as an affective economy of truth: fear slides between signs and sticks to bodies by constituting them as its objects. In making this argument, she shows how fear sticks to some bodies and not others. For example, the judgment that somebody "could be" a terrorist draws on past and affective associations that stick various signs (such as Muslim, fundamentalist, terrorist) together. At the same time, fear is reproduced precisely by the threat that such bodies "may pass (us) by." Such bodies become constructed as fearsome and as a threat to the very truths that are reified as "life itself." This paper hence shows how truth becomes an affective technique of containment in which the failure to contain is the justification of containment. The author concludes that if truth is a matter of containers and containment - about who or what gets contained to allow certain worlds to become given - then the risk taken by subaltern women, such as Rigoberta Menchú and Sunera Thobani, in speaking out against such truths is the risk of making an-other kind of world.  相似文献   

Exploring halaqah as research method: a tentative approach to developing Islamic research principles within a critical ‘indigenous’ framework     

Farah Ahmed 《International journal of qualitative studies in education》2013,26(5):561-583

This paper explores a traditional Islamic pedagogy known as halaqah as a potentially useful authentic research method and contributes to discourses about critical and indigenous research methodologies through an analysis of Islamization of Knowledge and other ‘critical indigenous’ movements amongst Muslims. Islamic research principles are tentatively proposed and then used to assess the effectiveness of halaqah as an authentic Islamic research method through analysis of a small qualitative study. The study involved Muslim mother-teachers participating in halaqah to collaboratively reflect on their work as holistic Islamic educators who are developing a ‘critical indigenous’ education to meet the needs of Muslim children in contemporary Britain. This paper argues that halaqah is a more authentic research method in this study than a group interview or focus group as it enabled participants to articulate themselves within their own epistemological and ontological context and engage in critical reflection within an Islamic paradigm.  相似文献
