Historical Aspects of State Arbitration Policy

This study examines state arbitration policy in Georgia from its establishment as a colony until the present time. It describes early informal and nonjudicialized procedures such as the Muhlenberg arbitration in Ebenezer in 1774; initiatives of the Georgia Legislature for the arbitral resolution of disputes; the application of arbitral devices in Georgia’s tax and municipal corporation law; arbitration in Georgia’s chambers of commerce and boards of trade, and forms of public law arbitration still existing in Georgia. The survey then shifts its attention to formal and judicialized arbitration in Georgia, focusing on the rise of uncodified common law arbitration in the nineteenth century and the adoption of formal Arbitration Codes in 1856, 1978; and 1988. The study concludes with reflections on modern challenges to the viability of state arbitration policy in Georgia, especially the risk of total federal preemption of Georgia arbitration policy initiatives

The longitudinal thickness of air-shower fronts

Linsely (1983) has proposed a technique for the detection and analysis of air showers at large distances from the shower axis based on a measurement of the shower front thickness and the assumption that this thickness is closely related to the core distance. Some of the problems involved with realizing such a technique were investigated, and some related observations are reported. The practical problems of how consistent the measurements of the shower front would be, how one would use the measurement, and how the rate of triggered events would depend on the minimum pulse width required are studied

Archeological Test Excavations in Areas to be Affected by a Proposed French Drain West of the Granary, Mission San Jose State Site (41BX3), Bexar County, Texas

Limited archeological test excavations were conducted along the west wall of the granary at Mission San Jose State Historic Site (41BX3) in Bex~r County, Texas, during July and August, 1979. The investigations were designed to provide information regarding the presence or absence of significant archeological materials in areas to be affected by the construction of a proposed French drain intended to relieve moisture-related structural problems along the west wall of the granary. six 0.5 by 1 meter test pits were excavated; 1,303 artifacts and 1,809 bone and shell fragments were recovered. Seven features were documented; these included a wall and a flagstone floor remnant, 4 pits and a limefilled trench. The wall and floor may represent the remains of a Spanish Colonial blacksmith shop while the pits probably originated during the late 19th Century. The artifacts are primarily trash resulting from nearly 240 years of activity at the mission complex although some items may be relatable to the smithy. Two alternatives for the proposed construc·tion are suggested: 1) abandon plans for a French drain and develop an alternate non-disruptive method for relieying moisture problems; or, 2) continue plans for constructing a French drain but precede the modifications with an intensive program of archeological excavations in a broad area along the west wall of the granary

The effects of the pre-pulse on capillary discharge extreme ultraviolet laser

In the past few years collisionally pumped extreme ultraviolet (XUV) lasers utilizing a capillary discharge were demonstrated. An intense current pulse is applied to a gas filled capillary, inducing magnetic collapse (Z-pinch) and formation of a highly ionized plasma column. Usually, a small current pulse (pre-pulse) is applied to the gas in order to pre-ionize it prior to the onset of the main current pulse. In this paper we investigate the effects of the pre-pulse on a capillary discharge Ne-like Ar XUV laser (46.9nm). The importance of the pre-pulse in achieving suitable initial conditions of the gas column and preventing instabilities during the collapse is demonstrated. Furthermore, measurements of the amplified spontaneous emission (ASE) properties (intensity, duration) in different pre-pulse currents revealed unexpected sensitivity. Increasing the pre-pulse current by a factor of two caused the ASE intensity to decrease by an order of magnitude - and to nearly disappear. This effect is accompanied by a slight increase in the lasing duration. We attribute this effect to axial flow in the gas during the pre-pulse.Comment: 4 pages, 4 figure

Statistical Arbitrage Mining for Display Advertising

We study and formulate arbitrage in display advertising. Real-Time Bidding (RTB) mimics stock spot exchanges and utilises computers to algorithmically buy display ads per impression via a real-time auction. Despite the new automation, the ad markets are still informationally inefficient due to the heavily fragmented marketplaces. Two display impressions with similar or identical effectiveness (e.g., measured by conversion or click-through rates for a targeted audience) may sell for quite different prices at different market segments or pricing schemes. In this paper, we propose a novel data mining paradigm called Statistical Arbitrage Mining (SAM) focusing on mining and exploiting price discrepancies between two pricing schemes. In essence, our SAMer is a meta-bidder that hedges advertisers' risk between CPA (cost per action)-based campaigns and CPM (cost per mille impressions)-based ad inventories; it statistically assesses the potential profit and cost for an incoming CPM bid request against a portfolio of CPA campaigns based on the estimated conversion rate, bid landscape and other statistics learned from historical data. In SAM, (i) functional optimisation is utilised to seek for optimal bidding to maximise the expected arbitrage net profit, and (ii) a portfolio-based risk management solution is leveraged to reallocate bid volume and budget across the set of campaigns to make a risk and return trade-off. We propose to jointly optimise both components in an EM fashion with high efficiency to help the meta-bidder successfully catch the transient statistical arbitrage opportunities in RTB. Both the offline experiments on a real-world large-scale dataset and online A/B tests on a commercial platform demonstrate the effectiveness of our proposed solution in exploiting arbitrage in various model settings and market environments.Comment: In the proceedings of the 21st ACM SIGKDD international conference on Knowledge discovery and data mining (KDD 2015

On the Hausdorff dimension of invariant measures of weakly contracting on average measurable IFS

We consider measures which are invariant under a measurable iterated function system with positive, place-dependent probabilities in a separable metric space. We provide an upper bound of the Hausdorff dimension of such a measure if it is ergodic. We also prove that it is ergodic iff the related skew product is.Comment: 16 pages; to appear in Journal of Stat. Phy

PENGEMBANGAN KOMODITAS TANAMAN PANGAN POKOK SEHUBUNGAN DENGAN PERKEMBANGAN PERMUKIMAN KAWASAN IBUKOTA KABUPATEN KUPANG

This research has been conducted in East Kupang District, Kupang Regency with the aim of knowing the superior staple food crop commodities and analyzing the zone dynamics of staple food crops as a result of changes in residential areas (housing and infrastructure) in 2013 and 2018 using the Geographical Information System (GIS). . The results showed that rice and green beans were the main staple crops in East Kupang District with an average LQ coefficient of 2.36 for rice and 1.29 for green beans, assuming there was no change in technology. The dynamics of the land zone for staple food crop commodities in East Kupang Subdistrict in the period 2013 and 2018, showed changes in residential land use covering an area of ​​1,104.37 hectares or the growth rate for settlements increased by 0.084% while the rate of decline in agricultural land for staple food crops was 0.0095% which means the rate of settlement increase is faster than the rate of decline in agricultural land for staple food crops

The Adequacy of Investment Choices Offered By 401K Plans

Defined-contribution plans represent a major organizational form for investors’ retirement savings. Today more than one third of all workers are enrolled in 401K plans. In a 401K plan, participants select assets from a set of choices designated by an employer. For over half of 401K-plan participants, retirement savings represent their sole financial asset. Yet to date there has been no study of the adequacy of the choices offered by 401K plans. This paper analyzes the adequacy and characteristics of the choices offered to 401K-plan participants for over 400 plans. We find that, for 62% of the plans, the types of choices offered are inadequate, and that over a 20-year period this makes a difference in terminal wealth of over 300%. We find that funds included in the plans are riskier than the general population of funds in the same categories. We study the characteristics of plans that are associated with adequate investment choices, including an analysis of the use of company stock, plan size, and the use of outside consultants. When we examine one category of investment choices, S&P 500 index funds, we find that the index funds chosen by 401K-plan administrators are on average inferior to the S&P 500 index funds selected by the aggregate of all investors
