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
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
A framework for delivering multicast messages in networks with mobile hosts
No full textTo accommodate mobile hosts (MHs) within existing data networks, the static network is augmented with “mobile support stations” (MSSs) that communicate directly with MHs, usually via wireless links. Connectivity of the overall network changes dynamically as MHs connect to the static network from different “locations” (MSSs) at different times. Compared to their desktop counterparts, mobile hosts face a new set of constraints namely, low bandwidth of the wireless links, tight constraints on power consumption and a significantly lower computing capability. Thus, even without considering failures, integration of mobile computers within existing networks pose a new set of problems. In this paper, we look at the problems associated with delivering multicast messages to mobile hosts. First, we identify how a mobile host’s ability to connect to different MSSs at different times, affects delivery of multicast messages and present schemes to deliver multicast messages to MHs from atleast-one location, from atmost-one location, and from exactly-one location. Next, we introduce “multicast groups” of mobile hosts wherein each multicast group is associated with a “host view”, a set of MSSs representing the aggregate location information of the group. A host-view membership algorithm is then presented and combined with the multicast scheme for exactly-once delivery. As a result, to deliver a multicast message to a specified group, copies of the message need be propagated only to the MSSs in the group’s host-view.Technical report DCS-TR-31
