The whole world, the Muslim in particular has witnessed conflicts in different areas, which have hindered the developmental efforts of the nations concerned. It should be learned that most victims of these conflicts are women and children. This article attempts to elaborate the role of Muslims Women as a crucial segment in civil society in initiating peace building through nurturing process. It maintains that the adoption of the principles and values derived from the Qur’ān and Sunnah of the Prophet is necessary as a process of lifelong learning.  Those identified values constituted the framework of this article and it adopts the textual analysis method.   This article concludes that through the implementation of those values and frameworks for peace building, women as one of the important segments of civil society are able to play significant role towards initiating peace building and promoting peaceful co-existence in pluralistic society. Abstrak: Dunia Islam khususnya telah menyaksikan konflik di pelbagai daerah yang berbeza. Konflik ini telah menghalang usaha kearah pembangunan Kawasan yang berkenaan. Kebanyakan mangsa konflik ini adalah wanita dan kanak-kanak. Artikel ini cuba untuk menghuraikan peranan wanita Islam sebagai segmen penting dalam masyarakat madani dalam membangun proses kedamaian dengan mendidik dan memupuk prinsip dan nilai murni janaan al-Qur’an. Penggunaan prinsip dan nilai yang dikutip dari ayat-ayat Qur'an dan hadis Rasulullah adalah keperluan yang mendesak sebagai wadah bagi proses pembelajaran sepanjang hayat. Nilai-nilai yang dikenal pasti merupakan rangka kerja artikel ini, dan metod yang dirujuk adalah analisis teks. Artikel ini menyimpulkan bahawa melalui pelaksanaan nilai-nilai dan kerangka kerja Islam bagi proses kedamaian, wanita Islam dalam masyarakat madani mampu memainkan peranan penting dalam memulakan pembinaan keamanan dan menggalakkan kehidupan yang harmonis, sejahtera dan saling bantu membantu dalam masyarakat majmuk.

The Relationship

ABSTRACT Understanding policy process involves many distinctive approaches. The most common are institutional, groups or networks, exogenous factors, rational actors, and idea-based approach. This paper discussed the idea-based approach to explain policy process, in this case policy change. It aims to analyse how ideas could assist people to understand policy change. What role do they play and why are they considered as fundamental element? It considers that ideas are belong to every policy actor, whether it is individual or institution. In order to answer these questions, this paper adopts Kingdon’s multi streams approach to analyse academic literatures. Through this approach, the relationship between ideas and policy change can be seen clearer. Ideas only can affect in policy change if it is agreed and accepted by policy makers. Therefore the receptivity of ideas plays significant role and it emerges policy entrepreneurs. They promote ideas (through problem framing, timing, and narrative construction) and manipulate in order to ensure the receptivity of ideas. Although policy entrepreneurs play significant role, political aspects remains the most important element in the policy process. Keywords: policy change, ideas, idea-based approach, Kingdon’s multiple streams, policy entrepreneurs.

Federal Sentencing

In federal criminal cases, federal law requires that judges consider the sentences other courts have imposed in factually similar matters. Courts and parties, however, face significant challenges in finding applicable sentencing precedents because judges do not typically issue written sentencing opinions, and transcripts of sentencings are not readily available in advanced searchable databases. At the same time, particularly since the Supreme Court’s 2005 decision in United States v. Booker, sentencing precedent has come to play a significant role in federal sentencing proceedings. By way of example, this article discusses recent cases involving defendants with gambling addictions, and recent cases involving college admissions or testing fraud. The article explores the ways the parties in those cases have used sentencing precedent in their advocacy, as well as the ways the courts involved have used sentencing precedent to justify their decisions. Given the important role of sentencing precedent in federal criminal cases, the article finally looks at ways in which the body of sentencing law could be made more readily available to parties and courts alike.

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder associated with rapidly progressing periodontitis leading to premature loss of deciduous and permanent dentition and diffuse palmoplantar keratosis. Immunologic alterations, genetic mutations, and role of bacteria are some aetiologic factors. Patients present with early periodontal destruction, so periodontists play a significant role in diagnosis and management. This paper reports a case of Papillon- Lefevre syndrome with its clinical manifestations and challenges for periodontal management which was diagnosed in dental department.

Holy City

Government of India launched a ‘Swadesh Darshan Scheme’ in January 2015 that pinpoints 13 designated circuits including Ramayana circuit, Krishna Circuit, Buddhist Circuit, and Spiritual Circuit to promote religious and cultural tourism in the country. Kurukshetra is a ‘Holy City’ of State of Haryana that is recently been added in ‘Krishna Religious Tourism Circuit’. ‘Krishna Circuit’ embraces inherent mythology and beliefs pertaining to Lord Krishna and includes different place of Haryana, Uttar Pradesh, Rajasthan, Gujrat, and Odisha for tourism facilitation. This scheme is alleged to contribute significantly in increasing the attractiveness of certain religious tourist destinations. Tourism entrepreneurs like hoteliers, restaurant owners, tour operators, travel agencies as well as religious entrepreneurs (Shinde, 2010) such as religious gurus, priests and managers of temples and ashrams are expected to get benefited from the initiatives proposed in the scheme in varied ways. Given the significant role of this scheme for growth of entrepreneurs, the present study aims to highlight the challenges faced by entrepreneurs that deserve attention of policy makers.
