Judicial accountability and economic policy outcomes: evidence from employment discrimination charges

How and whether judges should be held accountable is a key issue in the design of a legal system. Thirty-seven of the forty-eight continental states use some method of judicial selection which involves a direct role for citizens in selecting or re-appointing the judiciary. We identify two theoretical reasons why the method used for choosing judges is important – (i) a selection effect if the competence or underlying preferences of judges is affected, (ii) an incentive effect if the judges who are chosen behave differently because of the method used for their reappointment. This paper uses data from the U.S. to investigate whether judicial selection methods affect the number of employment discrimination charges filed for the period 1973- 2000. Our results show that states that appoint their judges have lower levels of discrimination charges compared to those that use some form of election. The results appear to be driven by states where judges being subject to re-election incentives rather than because judges with different preferences/competences are being chosen.

A Semantic Framework for Priority-based Service Matching in Pervasive Environments

The increasing popularity of personal wireless devices has raised new demands for the efficient discovery of heterogeneous devices and services in pervasive environments. The existing approaches such as Jini [1], UPnP [8], etc., describe services at a syntactic level and the matching mechanisms in these approaches are limited to syntactic comparisons based on attributes or interfaces. In order to overcome the limitations in these approaches, there has been an increased interest in the use of semantic description and matching techniques to support effective service discovery. This paper proposes a semantic matching approach which facilitates the discovery of device-based services in a pervasive environment; the approach provides a ranking facility that orders services according to their suitability and also considers priorities placed on individual requirements in a request during the matching process. The evaluation studies have shown that the matcher results correlate reasonably well with human judgement

A Semantic Approach for Description and Ranked Matching of Services in Pervasive Environments

With the recent developments in technology, new and diverse devices are being introduced into the pervasive world. This has raised new challenges for the discovery of devices and their services in dynamic environments. The existing approaches such as Jini [AOSJ99], UPnP [UPnP06], etc., describe services at a syntactic level and the matching mechanisms in these approaches are limited to syntactic comparisons based on attributes or interfaces. In order to overcome the limitations of these approaches, there has been an increasing interest in the use of Semantic Web technologies to support the description and matching of services. This paper proposes a semantic matching framework to facilitate effective discovery of device based services in pervasive environments. This offers a ranking mechanism that will order the available services in the order of their suitability; the evaluation of the experimental results have indicated that the results correlate well with human perception

Elation generalised quadrangles of order (s,p), where p is prime

We show that an elation generalised quadrangle which has p+1 lines on each point, for some prime p, is classical or arises from a flock of a quadratic cone (i.e., is a flock quadrangle).Comment: 14 page

FACTORS AFFECTING THE LIKELIHOOD OF CORN ROOTWORM BT SEED ADOPTION

The likelihood of adopting corn rootworm (CRW) Bt seed technology was analyzed using an ordered logit model. Data used to estimate the model came from USDAs 2001 Agricultural Resource Management Survey. Statistically significant variables include operator age, farm type, farm size, rootworm loss and current treatment for rootworm, off farm labor, and Bt technology for corn borer. The likelihood of adoption was not related to crop rotation, tillage system, new variant CRW region, or education.Crop Production/Industries,

Tracing potential energy surfaces of electronic excitations via their transition origins: application to Oxirane

We show that the transition origins of electronic excitations identified by quantified natural transition orbital (QNTO) analysis can be employed to connect potential energy surfaces (PESs) according to their character across a widerange of molecular geometries. This is achieved by locating the switching of transition origins of adiabatic potential surfaces as the geometry changes. The transition vectors for analysing transition origins are provided by linear response time-dependent density functional theory (TDDFT) calculations under the Tamm-Dancoff approximation. We study the photochemical CO ring opening of oxirane as an example and show that the results corroborate the traditional Gomer-Noyes mechanism derived experimentally. The knowledge of specific states for the reaction also agrees well with that given by previous theoretical work using TDDFT surface-hopping dynamics that was validated by high-quality quantum Monte Carlo calculations. We also show that QNTO can be useful for considerably larger and more complex systems: by projecting the excitations to those of a reference oxirane molecule, the approach is able to identify and analyse specific excitations of a trans-2,3-diphenyloxirane molecule.Comment: 14 pages, 12 figure

A Pragmatic Approach for the Semantic Description and Matching of Pervasive Resources

The increasing popularity of personal wireless devices has raised new demands for the efficient discovery of heterogeneous devices and services in pervasive environments. With the advancement of the electronic world, the diversity of available services is increasing rapidly. %This raises new demands for the efficient discovery and location of heterogeneous services and resources in dynamically changing environments. Traditional approaches for service discovery describe services at a syntactic level and the matching mechanisms available for these approaches are limited to syntactic comparisons based on attributes or interfaces. In order to overcome these limitations, there has been an increased interest in the use of semantic description and matching techniques to support effective service discovery. In this paper, we present a semantic matching approach to facilitate the discovery of device-based services in pervasive environments. The approach includes a ranking mechanism that orders services according to their suitability and also considers priorities placed on individual requirements in a request during the matching process. The solution has been systematically evaluated for its retrieval effectiveness and the results have shown that the matcher results agree reasonably well with human judgement. Another important practical concern is the efficiency and the scalability of the semantic matching solution. Therefore, we have evaluated the scalability of the proposed solution by investigating the variation in matching time in response to increasing numbers of advertisements and increasing request sizes, and have presented the empirical results

DEECD Early Childhood Intervention Reform Project

This literature review was commissioned by the Office for Children and Early Childhood Development, Department of Education and Early Childhood Development (DEECD), as part of its Early Childhood Intervention Services (ECIS) Reform Project (Stage 2): Developing Options and Next Steps. This Project aims to significantly enhance the efficiency, effectiveness and sustainability of Victoria’s ECIS system and improve outcomes for children with a disability or developmental delay and their families. Early childhood intervention services (ECIS) support children with a disability or developmental delay from birth to school entry and their families. ECIS provides special education, therapy, counselling, service planning and coordination, assistance and support to access services such as kindergarten and child care. The services funded through DEECD are provided by government Specialist Children\u27s Services teams and non-government Early Childhood Intervention agencies. In addition to the services provided by ECIS teams and agencies, the state and federal governments fund a range of complementary programs to support young children with developmental disabilities and their families. These include initiatives to support families (My Time parent groups, Family Support Packages), services to support inclusion (Preschool Field Officers, Inclusion Support Facilitators), and funding to support particular disability groups (Helping Children with Autism packages). These additional services and supports, together with the ECIS teams and agencies, make up the totality of early childhood intervention provision for young children with disabilities. The focus of the literature review is research on contemporary Australian and international evidence-based service delivery models for children with a disability, developmental delay or additional needs aged 0-8 years
