Impacts of the Fair and Equitable Tobacco Reform Act of 2004 on Shareholders’ Wealth in the Tobacco Industry

This study examines the impact and efficiency of the design of the Fair and Equitable Tobacco Reform Act of 2004 in deregulating the tobacco production industry. Results offer a number of policy implications of which deregulation of an economically challenged industry can be achieved without the use of taxpayer funds.Tobacco Buyout, Tobacco Industry, Event Study, Agribusiness, Agricultural and Food Policy,

FRESH VEGETABLE PRICE LINKAGE BETWEEN GROWER/SHIPPERS, WHOLESALERS AND RETAILERS

This study focused on the transmission of price adjustments between grower/shippers and wholesalers and between wholesale handlers and retailers of nine fresh vegetables (only the results associated with bell peppers are reported in this paper). Results among the nine vegetable products were not consistent with respect to the magnitude of adjustments or the time periods involved in the adjustments. In response to wholesale price changes, upward price adjustments at the retail level occur more quickly than do downward price adjustments. Price transmission relationships also varied among the vegetable products between the wholesaler and grower. Overall, the results indicate that factors in addition to changes in upstream prices are impacting retailers' and wholesalers' pricing decisions.Demand and Price Analysis,

Microwave remote sensing from space

Spaceborne microwave remote sensors provide perspectives of the earth surface and atmosphere which are of unique value in scientific studies of geomorphology, oceanic waves and topography, atmospheric water vapor and temperatures, vegetation classification and stress, ice types and dynamics, and hydrological characteristics. Microwave radars and radiometers offer enhanced sensitivities to the geometrical characteristics of the earth's surface and its cover, to water in all its forms--soil and vegetation moisture, ice, wetlands, oceans, and atmospheric water vapor, and can provide high-resolution imagery of the earth's surface independent of cloud cover or sun angle. A brief review of the historical development and principles of active and passive microwave remote sensing is presented, with emphasis on the unique characteristics of the information obtainable in the microwave spectrum and the value of this information to global geoscientific studies. Various spaceborne microwave remote sensors are described, with applications to geology, planetology, oceanography, glaciology, land biology, meteorology, and hydrology. A discussion of future microwave remote sensor technological developments and challenges is presented, along with a summary of future missions being planned by several countries

Reaction of Group III Biheterocyclic Complexes

Group III alkyl complexes supported by a ferrocene diamide ligand (1,1′-fc(NSitBuMe_2)_2) have been found to be reactive toward aromatic N-heterocycles such as 1-methylimidazole and pyridines. These reactions were investigated experimentally and computationally. An initial C−H activation event is followed by a coupling reaction to form biheterocyclic complexes, in which one of the rings is dearomatized. In the case of 1-methylimidazole, the biheterocyclic compound could not be isolated and further led to an imidazole ring-opened product; in the case of pyridines, it transformed into an isomer with extended conjugation of double bonds. Mechanisms for both reactions are proposed on the basis of experimental and computational results. DFT calculations were also used to show that an energetically accessible pathway for the ring-opening of pyridines exists

Charge transfer in overlapping gate charge-coupled devices

A detailed numerical simulation of the free charge transfer in overlapped gate charge-coupled devices is presented. The transport are analyzed in terms of thermal diffusion, self-induced fields, and fringing fields under all the relevant electrodes and interelectrode regions with time-varying gate potentials. The results of the charge transfer with different clocking schemes and clocking waveforms are presented. The dependence of the stages of the charge transfer on the device parameters are discussed in detail. A lumped-circuit model of CCD that could be used to obtain the charge-transfer characteristics with various clocking waveforms is also presented

Improving transport timetables usability for mobile devices: a case study

The increasing number of passengers using mobile devices like smartphones or tablets in last few years have motivated transport companies to develop mobile websites and apps for their customers. However, the transition from desktop to mobile versions is challenging and many websites are still not optimised for user experience on such devices. In this paper we present a usability study carried out with the timetables of Nottingham City Transport website. A number of design changes have improved the overall user experience as confirmed by the results

The influence of interface states on incomplete charge transfer in overlapping gate charge-coupled devices

A simple and accurate model is used to estimate the incomplete charge transfer due to interface states trapping in the overlapping gate charge-coupled devices. It is concluded that trapping in the interface states under the edges of the gates parallel to the active channel limits the performance of the devices at moderate and low frequencies. The influence of the device parameters, dimensions, and clocking waveforms on the signal degradation is discussed. It is shown that increasing the clock voltages, reduces the incomplete charge transfer due to interface state trapping

BamView: viewing mapped read alignment data in the context of the reference sequence

Summary: BamView is an interactive Java application for visualizing the large amounts of data stored for sequence reads which are aligned against a reference genome sequence. It supports the BAM (Binary Alignment/Map) format. It can be used in a number of contexts including SNP calling and structural annotation. BamView has also been integrated into Artemis so that the reads can be viewed in the context of the nucleotide sequence and genomic features

Trait self-control and beliefs about the utility of emotions for initiatory and inhibitory self-control

How do people with high trait self-control achieve their success? This research aimed to provide evidence for beliefs about emotion utility as a potential mechanism. Specifically, because beliefs about the utility of emotions predict emotion regulation and successful performance, we investigate the hypothesis that trait self-control influences beliefs about the utility of emotions for self-control. Two preregistered studies examined whether beliefs about the utility of emotions in everyday self-control situations varied depending on the person (trait self-control) and the situation (initiatory or inhibitory self-control). Our key finding was that people considered positive emotions more useful for self-control than negative emotions. This effect was also moderated by situational and individual factors, such that positive emotions were considered especially useful by participants with high trait self-control and in situations requiring initiatory self-control (with the opposite effect for negative emotions). This research suggests a potential role for instrumental emotion regulation in self-control success
