Sources of Output Growth in Indian Agriculture during the Post-Reform Period
Economic growth has failed to be sufficiently inclusive, particularly after the mid-nineties. Although agriculture is still a single major sector providing livelihood to more than 60 percent of the population, it has lost its growth momentum and the share has been declining continuously for a variety of reasons like low income due to inadequate output growth, low productivity, lack of credit at reasonable rates, natural calamities and unavailability of proper extension services. Realizing the importance of this sector and its current crisis, the Eleventh Plan aims to reverse this trend. Output growth could be possible by increasing input growth, technical progress and improvement in technical efficiency. In order to identify the source of the problem, this paper attempts to decompose the agricultural output growth obtained in 15 major states for the period 1994-95 to 2003-04 into the above three components using the random coefficients frontier production function model. Results of the study indicate that the efficiency has declined over time for all the states and the average technical efficiency is only 72 percent. This means that there is a potential to increase the existing output by 28 percent without increasing inputs.We found that inmost of the states, growth was only due to higher inputs. Investment in extension services along with sustained investment in agricultural research and development, and infrastructure is the need of the hour. West Bengal is the most efficient state in applying labor and fertilizer inputs and also has a very high over all efficiency. This can be linked to the successful land reform policies of the state.economic growth, technical efficiency, Eleventh Plan, frontier production function, land reform
Preserving Stabilization while Practically Bounding State Space
Stabilization is a key dependability property for dealing with unanticipated
transient faults, as it guarantees that even in the presence of such faults,
the system will recover to states where it satisfies its specification. One of
the desirable attributes of stabilization is the use of bounded space for each
variable. In this paper, we present an algorithm that transforms a stabilizing
program that uses variables with unbounded domain into a stabilizing program
that uses bounded variables and (practically bounded) physical time. While
non-stabilizing programs (that do not handle transient faults) can deal with
unbounded variables by assigning large enough but bounded space, stabilizing
programs that need to deal with arbitrary transient faults cannot do the same
since a transient fault may corrupt the variable to its maximum value. We show
that our transformation algorithm is applicable to several problems including
logical clocks, vector clocks, mutual exclusion, leader election, diffusing
computations, Paxos based consensus, and so on. Moreover, our approach can also
be used to bound counters used in an earlier work by Katz and Perry for adding
stabilization to a non-stabilizing program. By combining our algorithm with
that earlier work by Katz and Perry, it would be possible to provide
stabilization for a rich class of problems, by assigning large enough but
bounded space for variables.Comment: Moved some content from the Appendix to the main paper, added some
details to the transformation algorithm and to its descriptio
Homo economicus in visual search
How do reward outcomes affect early visual performance? Previous studies found a suboptimal influence, but they ignored the non-linearity in how subjects perceived the reward outcomes. In contrast, we find that when the non-linearity is accounted for, humans behave optimally and maximize expected reward. Our subjects were asked to detect the presence of a familiar target object in a cluttered scene. They were rewarded according to their performance. We systematically varied the target frequency and the reward/penalty policy for detecting/missing the targets. We find that 1) decreasing the target frequency will decrease the detection rates, in accordance with the literature. 2) Contrary to previous studies, increasing the target detection rewards will compensate for target rarity and restore detection performance. 3) A quantitative model based on reward maximization accurately predicts human detection behavior in all target frequency and reward conditions; thus, reward schemes can be designed to obtain desired detection rates for rare targets. 4) Subjects quickly learn the optimal decision strategy; we propose a neurally plausible model that exhibits the same properties. Potential applications include designing reward schemes to improve detection of life-critical, rare targets (e.g., cancers in medical images)
Monoclonal antibodies in fish and shellfish health management in India
The paper describes the superiority of monoclonal antibodies (MAb) over conventional polyclonal antisera. Studies undertaken indicate that Aeromonas hydrophila isolates are highly heterogenous and variation exists even between isolates from a farm, requiring a large number of MAbs for classification and use of information in vaccine development. However, some of the MAbs could be used for detection of homologous isolates in fish kidney by immunodot assay and evaluation and standardization of biofilm of A. hydrophila for oral vaccination in carps
Impact of Sexual Abuse on Children and Intervention Strategies
Child sexual abuse is a form of child abuse in which an adult or older adolescent uses a child for sexual stimulation. Forms of child sexual abuse include asking or pressuring a child to engage in sexual activities, indecent exposure of body parts to a child with intent to gratify their own sexual desires or to intimidate or groom the child, physical sexual contact with a child or using a child to produce child pornography. The effects of child sexual abuse can include depression, post-traumatic stress disorder, anxiety and propensity to further victimization in adulthood and physical injury to the child. Protection of children against sexual abuse Act,2012 brings many incidents of sexual abuses into light and judgments are given immediately by special courts and. Intervention strategies like individual Therapy, Play Therapy and Family Therapy can be used to deal with children. Keywords: Abuse, psychological disturbance, inces
Development of a GIS-based safety analysis system
The objective of this study is to develop a safety analysis system that integrates crash data and roadway related information. This system is developed in a Geographic Information System (GIS) environment. It includes customized user interfaces to support queries to analyze data and to display results either in graphical or tabular formats. The system also affords the capabilities to export such results. The system permits analyses to be performed either at individual locations such as intersections, or for roadway segments. These analyses are based on data fields included in the crash database. The queries may be based on individual attributes recorded in the crash database or by combining multiple attributes from the database. The system also contains a module to identify high crash locations based on methods identified from the published literature. The methods range from those based on simple crash frequency to more complex methods which incorporate different weights for crashed based on the crash outcomes. An application of the system is illustrated using data from the Las Vegas metropolitan are in the state of Nevada; The system can be used to identify safety issues in a region, and to plan and deploy appropriate countermeasures to enhance safety. It also can be used to monitor the effectiveness of traffic safety programs. Such a system could also be used to screen projects and operational strategies to be funded in through appropriate funding processes
