Abstract: Acoustics in buildings is that part of science in which importance has been given to the sound quality in building, which enables a proper understanding of the different factors influencing the same. Acoustics being one of the important factor which enables in reduction of transmission of noise and enable a better sound quality in the room. But however either very less or insufficient amount of work has been put in considering the scope of the subject. Some other limitations are builders either do not give priority to that aspect due to lack of information or the improper design and poor implementation. Also The Indian Standard Codes in this area are too old and need updation considering the Modern Scenario and Modern Construction Practices. So efforts have been made to consider this situation and find the best practices, recent innovations and methodologies which could help in maintaining proper Acoustics in Buildings, Halls, Auditorium's etc. And what role could a Civil Engineer play in elimination of this problem. Keywords: Acoustics, Buildings, Material Properties

Content management is an organisational effort of managing content, particularly in digital format. Although it has been over 25 years since content management was introduced, this field of study is still considered an emerging topic with unresolved issues-in particular, the subject of benefit achievement. Therefore, grounded on an extensive review of 135 articles, the purpose of this study is to investigate the benefits that organisations can gain through the proper use of an Enterprise Content Management System (ECMS). Subsequently, this paper identifies a list of ECMS benefits and proposes an ECMS benefit framework for further exploration into this field. Our result shows that although ECMS does bring benefits to organisations, these benefits are diverse; indicating that there are certain determinants or factors influencing the achievement of such benefits. Moreover, it is also found that in the context of the benefit framework of Shang and Seddon [10], three categories were found relevant to the field of content management: operational benefit, managerial benefit, and strategic benefit.

Human body is a complex of organic substances (proteins, lipids, carbohydrates), which undergo chemical decomposition processes soon after death. The compounds released during decomposition characterize the development of different stages of this process: e.g. biogenic amines resulted from the proteins decomposition will confer the particular smell of a cadaver, gases resulted from carbohydrates fermentation will give the bloating aspect of the cadaver. The study of cadaver decomposition and the products resulted from this process is the subject of human taphonomy and is realized nowadays in special facilities in USA and Australia. Identification and analysis of the chemical compounds emerged after human decomposition (gases, liquids, salts) give valuable information to forensic pathologists for estimating the postmortem interval (PMI). More, volatile compounds � which give the odor signature�specific to human remains � may be utilized in identifying clandestine burials, human remains or victims entrapped under ruins in cases of natural disasters. In this paper the authors describe the chemical decomposition stages of human cadavers, the factors influencing these processes and utility for the forensic activity of the results of human taphonomic studies.

Background: The theoretical background of this article is on the model developed of knowledge transfer between universities and the industry in order to access the best practices and adapt to the study case in question regarding the model of promoting and manage innovation within the universities that best contribute with solution and projects to the business field. Objective: The development of a knowledge transfer model is the main goal of this article, supported in the best practices known and, also, to reflect in the main measurement definitions to evaluate the High Education Institution performance in this area. Methods: The method for this article development is the case study method because it allows the fully understanding of the dynamics present within a single setting, and the subject examined to comprehend what is being done and what the dynamics mean. The case study does not have a data collection method, as it is a research that may rely on multiple sources of evidence and data which should be converged. Results: Since it’s a case study this article present a fully description of the model proposed and implemented for the knowledge transfer process of the institution. Conclusion: Still in a discussion phase, this article presents as conclusions some questions and difficulties that could be pointed out, as well as some good perspectives of performed activity developed.

“Arminianism” was the subject of important theological controversies in the seventeenth and eighteenth centuries, and it maintains an important position within Protestant thought. What became known as “Arminian” theology was held by people across a swath of geographical and ecclesial positions; it developed in European, British, and American contexts, and it engaged with a wide range of intellectual challenges. While standing together in their common rejection of several key planks of Reformed theology, proponents of Arminianism took various positions on other matters. Some were broadly committed to catholic and creedal theology; others were more open to theological revision. Some were concerned primarily with practical concerns; others were engaged in system building as they sought to articulate and defend an overarching vision of God and the world. The story of this development is both complex and important for a proper understanding of the history of Protestant theology. However, this historical development of Arminian theology is not well known. In this book, Thomas H. McCall and Keith D. Stanglin offer a historical introduction to Arminian theology as it developed in modern thought, providing an account that is based upon important primary sources and recent secondary research that will be helpful to scholars of ecclesial history and modern thought as well as comprehensible and relevant for students.

The implementation of sustainability and green public procurement (GPP) initiatives in school districts has been the subject of some debate; questions over definitions and programme goals have led to inconsistency and concerns about programme achievements. The legitimacy of programmes rests not only with the announcement of policy by officials, but with adherence to policy and staff buy-in. This study examines barriers districts face, and makes recommendations based upon district experience on ways to successfully implement sustainability and GPP initiatives. A review of the literature on GPP and legitimacy in the execution of public functions within the education domain begins the study. Major components relative to best practices for GPP programmes are studied through the review of GPP-related documents from a school district in New Jersey considered as an exemplar of such programmes. Analysis of an interview with the district’s representatives suggests that, despite the normative approval such programmes receive, and widespread understanding of the rationale for pursuing such initiatives, there remain critical failings in implementation of these programmes, stemming from education, resourcing of initiatives and prioritization of green procurement in relation to other district priorities. The study concludes with lessons learned from this case, which is important given its positioning within New Jersey as an exemplar and recommendations for future research where work in this area is needed.

The lack of information related to the best practices in responsible tourism is one of the causes to tourist behavior problems. This study aims to determine the behavior of tourists in hiking, the adoption of responsible tourism practices, and to compile a responsible tourism practices guidebook. The research method used is survey research by spreading the questionnaire. Based on Likert analysis, at the pre-ascending stage, the classification of attitudes indicated by the respondents for cost and transportation is quite agreeable, while for equipment, guide, and simaksi is agreed. The ascent stage, the indicator when going up the mountain is quite agree, camping is not agree, the cook is agree, and when down the mountain is strongly agree. The post-ascent stage shows quite agreeable attitude. The public test of the guidebook, for the aspect of size and language of submission shows an agreeable attitude, while for the design, thickness, and content of the book shows an agreeable attitude. The conclusion is that (1) Still found the behavior of tourists in mountain climbing that is not environmentally friendly, (2) The responsible tourism practices of mountaineering that includes pre-ascending, ascent, and post-ascent, not well implemented by tourists, and (3) The responsible tourism practices guidebook still lack both technical and substance. Keywords: responsible tourism, mountain hiking, guidebook, tourist behavior

Objective - The term “best practice” appears often in library and information science literature, yet, despite the frequency with which the term is used, there is little discussion about what is meant by the term and how one can reliably identify a best practice. Methods – This paper reviews 113 articles that identify and discuss best practices, in order to determine how “best practices” are distinguished from other practices, and whether these determinations are made on the basis of consistent and reliable evidence. The review also takes into account definitions of the term to discover if a common definition is used amongst authors. Results – The “evidence” upon which papers on “best practices” are based falls into one of the following six categories: 1) opinion (n=18, 15%), 2) literature reviews (n=13, 12%), 3) practices in the library in which the author works (n=19, 17%), 4) formal and informal qualitative and quantitative approaches (n=16, 14%), 5) a combination of the aforementioned (i.e., combined approaches) (n=34, 30%), and 6) “other” sources or approaches which are largely one of a kind (n=13, 12%). There is no widely shared or common definition of “best practices” amongst the authors of these papers, and most papers (n=94, 83%) fail to define the term at all. The number of papers was, for the most part, split evenly amongst the six categories indicating that writers on the subject are basing “best practices” assertions on a wide variety of sources and evidence. Conclusions – Library and information science literature on “best practices” is rarely based on rigorous empirical methods of research and therefore is generally unreliable. There is, in addition, no widely held understanding of what is meant by the use of the term.

This paper is an attempt so to construe the arguments of the Hippias Minor as to remove the justification for regarding it as unworthy of Plato either because of its alleged fallaciousness and Sophistic mode of argument or because of its alleged immorality. It focuses, therefore, only on the arguments and their conclusions, steering clear of the dialogue's dramatic and literary aspects. Whereas I do not wish to deny the importance of these aspects to a proper understanding of the dialogue – on the contrary, in a dialogue so heavily laden with irony and caricature, these aspects are necessarily more significant than they are in other dialogues – I do think there is something to be gained from concentrating on the arguments themselves. Although there can be little doubt that Socrates is up to something in the Hippias Minor, the task of determining just what he is up to can only be simplified by clarifying the arguments first.The Hippias Minor has traditionally been thought to contain two independent arguments, each having its own paradoxical conclusion. The first argument begins, it is said, when Hippias characterizes the two Homeric heroes Achilles and Odysseus as the true man (⋯ ⋯ληθ⋯ς) and the false man (⋯ ψευδ⋯ς) respectively. Through its discovery that both the false man and the true man have δύναμις, it results in the paradox that the false man and the true are identical. The second argument, on this view, leaves the subject of ⋯ ⋯ληθ⋯ς and ⋯ ψευδ⋯ς and compares instead all sorts of agents in intentional and unintentional action. Finding that the intentional agent is in every case better than the unintentional, the argument concludes that the intentional evil-doer is also better than the unintentional. Viewing the dialogue as thus containing two distinct topics treated in two self-sufficient arguments is perhaps not the best way to understand it.

In recent years, Aristotle's treatment of the imagination has become the subject of renewed interest. A pioneering paper by Malcolm Schofield argued that, far from being the rag-bag of widely separate and more or less unrelated concerns that it had previously been generally taken to be, phantasia was, for Aristotle, a ‘loose-knit family concept’ covering all aspects of what Schofield labelled ‘non-paradigmatic sensory experience’. With that conclusion I am more or less in agreement, although only on the condition that ‘sensory’ be given a suitably broad interpretation. My purpose in this paper is to tease out, in a necessarily limited and circumscribed manner, the implications of a proper understanding of Aristotle's developed concept of deliberative imagination, phantasia bouleutikê, for his moral theory and his account of rational action, and to indicate ways in which this is related to his accounts of mental imaging in the rest of the Parva Naturalia.
