Use of K-Means Clustering Method for Books Data in Acharya Raghuveer Library, Central University of Himachal Pradesh, Dharamshala, India
No full textPurpose- The study formulates clusters of Library and Information (LIS) discipline books from Acharya Raghuveer Library, Central University of Himachal Pradesh. Cluster formulation aims to identify the utilization rate of books. Furthermore, the study attempts to find the direction for collection management and developing related services for the users in the library.
Design/methodology/approach- Books circulation data set is obtained, formatted and made compatible for further analysis. The Euclidean distance formula is used to find the distance between two points on a plane. Afterwards, the K-means clustering algorithm is implemented to generate the required clusters.
Findings- Three clusters of books namely, Frequently Borrowed books (C1), Rarely Borrowed Books (C2) and Most Frequently Borrowed Books (C3) are derived. Out of a total of 30 book records, 19 books are grouped as often borrowed books, 6 books are grouped as rarely borrowed books and 5 books are grouped as most frequently borrowed books.
Originality/value- The study points out the importance and applicability of data analysis to examine the patterns of resource usages in libraries. Further comprehensive study with data analysis may give directions for collection development and management in libraries
Africa in global International relations: emerging approaches to theory and practice: an introduction
No full textThis book investigates why Africa has been marginalised in IR discipline and theory and how this issue can be addressed in the context of the emerging Global IR paradigm. To have relevance for Africa, a new IR theory needs to be more inclusive, intellectually negotiated and holistically steeped in the African context. In this innovative volume, each author takes a critical look at existing IR paradigms and offers a unique perspective based on the African experience. Following on from Amitav Acharya and Barry Buzan’s work, Non-Western International Relations Theory, it develops and advances non-Western IR theory and the idea of Global IR
A Scalable Interconnection Architecture for Future Many-Core Systems
No full textIn this thesis, a scalable interconnection architecture for many-core systems is proposed and the tradeoffs in the design of this architecture are described. Using this model we investigate how the other aspects of network architecture like routing strategy, routing algorithms, buffer space and traffic pattern impact the performance of interconnection network. This report also discusses the simulation environment and the trace-driven simulation approach used for the simulation. The traces are obtained from NAS parallel benchmark using the MPICH application. The simulation is performed for two network models 2-d MESH and CMESH. These models are then subjected to two different approaches of traffic injection: inject as fast as you can, and follow casual order for the injection. The performance of these network models is then compared for the worst case scenario: inject as fast as you can, network backpressure maintains the flow of traffic into network. The variable message size, buffer space and routing algorithm are the variables for which the network performance is measured. This study shows that the choice of network architecture depends upon the priority of the network design. Had it been just achieving lower average message latency regardless of area occupied, power consumed and requirement of buffer space, MESH is a better choice. On the other hand, for the on-chip interconnection architecture where space, power constraints and bufferspace plays a major role; CMESH presents a better choice with the expense of little more router computation complexity and greater average message latency
Adverse Family Experiences Are Associated With Age of Diagnosis Among Children With Autism Spectrum Disorder
No full textAbstract
Date Presented 4/1/2017
Adverse childhood experiences (ACEs) may pose a significant barrier to timely diagnosis of autism spectrum disorder among U.S. children. By identifying ACEs early in a family’s history, occupational therapy practitioners have the opportunity to reduce family stress and support parents in meeting their children’s treatment needs.

FOLLOWING (F)INSTAGRAMS: DELINEATING SOCIAL BOUNDARIES ONLINE
No full textThe duality of "insta" vs. "finsta" is a binary that assumes that users can be more candid in the latter "fake" (often eulogized as "fun") Instagram = Finstagram account. While the "real" Instagram is more aesthetically pleasing, it indexes an added effort put into curating it. The paper argues that this is a false paradox in the perceived visual and sensory authenticity in the two account types of the same user. In this essay the author empirically describes users’ experience mediating these two accounts through primary research centered around Berger and Luckmann’s Social Construction of Reality, Robert Merton’s
Insiders and Outsiders, and Erving Goffman’s Presentation of
Self in Everyday Life through this dialectic of so-called fake instas
(finsta) and real instas (rinsta). In doing so, it empirically addresses
these questions: How does Instagram mediate the construction of self in everyday reality? How do users participate and perform in this construction?Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/177333/1/12-Acharya-Finstagrams-Social Media and Society in India Proceedings-41-49-10.73027930.pdfSEL
India’s Macroeconomic Performance and Policies since 2000
No full textThe paper reviews Indias macroeconomic performance and policies since 2000. The first section briefly summarizes key macroeconomic developments regarding economic growth, inflation, external balance, the fiscal situation and aggregate savings and investment. The second section considers some of the challenges posed to macroeconomic management in this period and the efficacy of the policy responses adopted. In particular, it analyses the progress in fiscal consolidation and the policies adopted to deal with the challenge of the unprecedented surge in external capital inflows into India. The final section outlines some of the major macro policy issues that need to be addressed in the years ahead, including : the resurgence of high fiscal deficits; the issues relating to external convertibility and exchange rate management; the role of the Reserve Bank of India in macroeconomic policy and coping with a weak international economic environment.economic growth, inflation, Fiscal Policy, savings and investment, Capital Inflows, exchange rate policy, central bank role
Utility and profit maximization in dynamic spectrum allocation
No full textDemand driven, short term allocation of spectrum will be important for future wireless systems. Engineering and economics will jointly determine optimal ways to operate such systems. In this thesis, we characterize two operating principles of dynamic spectrum access: decentralized commons and centralized property right.
In decentralized commons, co-located devices sense spectrum for vacant bands to transmit. Assuming an OFDM based physical layer, this means that a device can transmit in non contiguous tones. We analyze how symbol timing synchronization can be achieved using cyclic prefix based algorithms. For different spectral occupancies of the transmitter and fading conditions, we identify scenarios where synchronization algorithms yield satisfactory results and scenarios where they do not.
For the centralized property rights regime, we develop a two tiered spectrum allocation model where spectrum is first allocated to service providers (SPs) by a broker and then to customers by SPs.
First we assume that the users transmit to the SPs in the uplink after spectrum allocation, who maximize the sum utility of the users. We derive optimal allocation for different system parameters. We introduce a spectrum price and use it to demonstrate several key results about spectrum allocation. The spectrum price proves to be the regulatory mechanism that brings about coordination amongst the SPs with minimal control messaging. Our approach thus strikes a balance between a total and no central coordination.
Next we consider a downlink scenario where SPs sell spectrum to users and then transmit data. The SPs operate to maximize their profits. Each SP transmits at a specific power spectral density which is an indicator of the modulation and coding technology used for transmission. When there is only one SP, it can act as a monopolist and when there are multiple SPs, they compete. We characterize the customer to SP interactions in monopoly and SP price competition. We derive the prices charged and profits made by the SPs and show how they vary with provider efficiencies and spectrum costs charged by the broker. We show that an SP should invest in better technology if the broker cost of spectrum is high.Ph.D.Includes bibliographical references (p. 105-110)by Joydeep Achary
Ethical perspectives of direct-to-consumer genetic testing
No full textDirect-to-consumer (DTC) genetic testing, which evolved from genomics is not free from controversies and ethical dilemmas. Conduction of genetic testing without direct communication between the users and certified medical professionals has aroused many ethical concerns. We discuss some ethical dilemmas surrounding DTC genetic testing in terms of quality assurance of the test, information communication process of the result, confidentiality of test result and the right to privacy, cost and price regulations, and user safety and harm mitigation. DTC genetic testing lies in the middle of a clash between liberal trade policies and state’s regulations as a case of extreme paternalism. However, priority should be given to prevent any undesirable consequences to the users with proper regulations
Human Resource for Health Migration: An Analysis from the Perspective of Utilitarianism
No full textAlthough brain drain started out as a process of movement of skilled professionals within the developed countries, the more recent trend of exodus of professionals from the less developed countries to the affluent ones has raised serious concerns. The ongoing trend of brain drain of health professionals has led to the shortage of human resource for health in the resource-limited source countries while allowing the destination countries to reap the benefits without any substantial investment in producing those cadres of qualified health professionals. This article discusses the brain drain of health professionals in the light of benefit and loss in the context of both the source and destination countries with utilitarianism perspective in mind
