The Spatial Data Infrastructure (SDI) has emerged to facilitate the access, delivery and share of spatial information. It also results in greater effi ciency as limited awareness of existing datasets can lead organizations to duplicate data collection and register. SDI is an initiative that creates an environment in which spatial data stakeholders from different jurisdictions can co-operate and...

This study was conducted to determine the effects of red light exposure on the productivity, fertility and hatching characteristics in Thai native hens (Gallus domesticus). A total of 120 birds aged 18 wk were housed in an open-sided shed and exposed to one of the following lighting treatments: 1) natural daylight supplemented with fl uorescent light (Control), 2) natural daylight supplemented ...

At present, material properties are being continuously improved in line with current technological developments to meet operational and safety standards. Designers consumers now look for materials that more energy effi- cient, stronger, lighter as well cheaper. A metal-matrix composite (MMCs) will represents a dominant class of which can be suitably designed the above requirements. With variety...

Weiss, Fakulty of Mining, Ecology, Process C ontrol a nd G eotechnology, Technical Un iversity o f Ko šice, Slovakia The present paper focuses on the effi ciency improvement of the strategic raw material (iron ore) purchase process in a metallurgical company and its management with the aim to minimize costs. The authors have come up with the proposals for an effi c...

A well known and simple game to model markets is the glove game where worth is produced by building matching pairs. For glove games, diff erent concepts, like the Shapley value, the restricted Shapley value or the Owen value, yield diff erent distributions of worth. Moreover, computational eff ort of these values is in general very high. This paper provides effi cient allocation formulas of the...

the paper attempts to study the efficiency of crop production and resource use effi-ciency on temple tenants and owner farms in tirunelveli district of tamil nadu. a sam-ple of 90 temple tenants and 50 owner farmers from two taluks of tirunelveli district, nawely, shencottah and tenkasi were selected for the study. the reference period of the study was 2002-2003. the efficiency analysis with th...

i s t r y he demand for fl at, lightweight television and computer displays has given rise to many different fl at-panel display technologies. Recently, much emphasis has been placed on organic light emitting diodes (OLEDs), chemical systems which have the potential to be not only smaller and lighter, but also more energy effi cient than other current display technologies. The most common form ...

We solve and test experimentally a global game of speculative attack where agents choose, at a cost, the precision of their private signal. We prove existence of a unique equilibrium in the coordination game and explore strategic incentives in information acquisition. In the experiment, we find that subjects follow the strategies suggested by the theory. However, contrary to our predictions, as...

This paper presents a dynamic equilibrium model of information aggregation which occurs through locally intermediated trading in a large population. We analyze how dispersed information is aggregated over time, and how it affects allocations overtime. The model exhibits excess trading due to information aggregation. We show that in the absence of private signals, dynamic trading leads to the ex...

Current guidelines recommend metformin as initial therapy in patients with type 2 diabetes.1 With time, as β cell function declines, most patients require additional therapy.2 While there is now an expanding list of drugs available to be used as second-line agents, studies that directly compare the effi cacy of these agents are lacking.1 The choice of a second-line agent is, therefore, less cle...
