Parallel memory processing by the CA1 region of the dorsal hippocampus and the basolateral amygdala

There is abundant literature on the role of the basolateral amygdala (BLA) and the CA1 region of the hippocampus in memory formation of inhibitory avoidance (IA) and other behaviorally arousing tasks. Here, we investigate molecular correlates of IA consolidation in the two structures and their relation to NMDA receptors (NMDArs) and β-adrenergic receptors (β-ADrs). The separate posttraining administration of antagonists of NMDAr and β-ADr to BLA and CA1 is amnesic. IA training is followed by an increase of the phosphorylation of calcium and calmodulin-dependent protein kinase II (CaMKII) and ERK2 in CA1 but only an increase of the phosphorylation of ERK2 in BLA. The changes are blocked by NMDAr antagonists but not β-ADr antagonists in CA1, and they are blocked by β-ADr but not NMDAr antagonists in BLA. In addition, the changes are accompanied by increased phosphorylation of tyrosine hydroxylase in BLA but not in CA1, suggesting that β-AD modulation results from local catecholamine synthesis in the former but not in the latter structure. NMDAr blockers in CA1 do not alter the learning-induced neurochemical changes in BLA, and β-ADr blockade in BLA does not hinder those in CA1. When put together with other data from the literature, the present findings suggest that CA1 and BLA play a role in consolidation, but they operate to an extent in parallel, suggesting that each is probably involved with different aspects of the task studied.
Forecasting Chinese Stock Market with Extreme Values

By decomposing stock returns with high-low extreme values, this paper investigates the predictability of Chinese stock market with a vector autoregressive model. Empirical studies, both in-sample and out-of-sample, performed on the Shanghai Stock Exchange Composite Index (SSEC) show that the SSEC is highly predictable in both statistical and economic sense. The findings obtained in this paper are based on history price information, which hints that the Chinese stock market might not be weakly efficient.
High Salt Concentrations Increase Permeability through OmpC Channels of Escherichia coli*

Background: OmpC porin is less permeable than OmpF, but there is little difference in channel size. Results: There are more charged residues in the OmpC channel, and mutating them or increasing ionic strength made it more permeable and OmpF-like. Conclusion: Charged residues produce the low permeability of OmpC. Significance: OmpC, produced in a high ionic strength environment, has properties optimized for this environment. OmpF and OmpC porin channels are responsible for the passage of small hydrophilic solutes across the outer membrane of Escherichia coli. Although these channels are two of the most extensively studied porin channels, what had yet remained elusive was the reason why OmpC shows markedly lower permeability than OmpF, despite having little difference in its channel size. The OmpC channel, however, is known to contain a larger number of ionizable residues than the OmpF channel. In this study, we examined the channel property of OmpF and OmpC using the intact cell of E. coli, and we found that the permeability of several β-lactams and lactose through OmpC became increased to the level comparable with OmpF with up to 0.3 m salt that may increase the Debye-Hückel shielding or with 2% ethanol or 0.3 m urea that may perturb the short range ordering of water molecules. Replacing 10 pore-lining residues that show different ionization behavior between OmpC and OmpF led to substantial conversion of channel property with respect to their permeability and response to external salt concentration. We thus propose that the overall configuration of ionizable residues in the channel that may orient water molecules and the electrostatic profile of the channel play a decisive role in defining the channel property of the OmpC porin rather than its channel size.
Integrated low-voltage pulse width modulation circuit using CMOS processes

A low-voltage low-power integrated pulse-width-modulation (PWM) circuit using CMOS processes is presented in this paper. The proposed PWM circuit only consists of CMOS transistors and can be implemented with digital CMOS processes without extra internal or/and external passive components. In the proposed circuit, the curve-compensation technique is used to achieve approximately constant frequency operation. This circuit will be useful in low-voltage multimedia circuit, power electronic and telecommunication applications.
Related Party Transactions, Family Firms and Firm Performance: Some Malaysian Evidence

We examine the link between related party transactions (RPT) and firm performance, and also whether RPT in family firms are more likely to be used opportunistically to expropriate minority shareholders, hence lower the firm performance. Using regression analysis of 462 Malaysian companies, we show that RPT is negatively associated with firm performance. Further, we also show that this association is stronger for family firms than non-family firms. The findings suggest that RPTs carried out by family firms, are more likely to be used opportunistically to expropriate minority shareholders. The evidence is consistent with entrenchment hypothesis and tunneling.
Expressiveness, Efficiency, and Privacy in Advertising Auctions

Internet search results are a growing and highly profitable advertising platform. Search providers auction advertising slots to advertisers on their search result pages. Due to the high volume of searches and the users' low tolerance for search result latency, it is important to resolve these auctions quickly. Current approaches restrict the expressiveness of bids in order to achieve fast winner determination, which is the problem of allocating slots to advertisers so as to maximize the expected revenue given that advertisers are charged what they bid. The goal of this work is to permit more expressive bidding, thus allowing advertisers to achieve complex advertising goals, while still providing fast and scalable techniques for winner determination. To this end, we allow advertisers to submit programs that express complex and dynamic bidding strategies. We provide techniques for reducing the amount of program evaluation necessary to solve the winner determination problem, and we study the complexity of sharing aggregation computations between these programs. In addition, we also examine the problem of providing advertisers with data about search auctions without disclosing too much about any individual. We provide algorithms for both checking and enforcing privacy in this context.
Brand loyalty in emerging markets

Purpose – This paper seeks to compare some key antecedents of brand loyalty between two emerging markets: Thailand and Vietnam.Design/methodology/approach – Using a sample of 603 female consumers of international shampoo brands, including 304 consumers in Bangkok, Thailand and 299 users in Hanoi, Vietnam, a model was tested that incorporates key determinants of brand loyalty – perceived quality, brand awareness, advertising attitudes, and distribution intensity – by means of structural equation modeling.Findings – The paper found that there are positive relationships between perceived quality and brand loyalty, between brand awareness and perceived quality, between advertising attitudes and brand awareness, and between distribution intensity and brand awareness in both markets. However, the relationship between brand awareness and brand loyalty was found only in the Vietnamese market, and the relationship between advertising attitudes and perceived quality was only found in the Thai market. Finally, no re.
Use of BIS monitor in a child with congenital insensitivity to pain with anhidrosis

We describe a case of a 14‐year‐old boy with congenital insensitivity to pain and anhidrosis (CIPA) who underwent tarsal tunnel release for tarsal tunnel syndrome. Because of abnormal pain perception, the patient's response to normally painful surgical stimuli is severely impaired and not adequately reflected in a corresponding rise in blood pressure or heart rate. This lack of autonomic feedback to pain stimuli may make it more difficult to assess whether anesthetic depth is adequate to prevent intraoperative awareness and thus to safely conduct anesthesia, especially if muscle paralysis is required for surgical indications. We describe for the first time the use of processed EEG monitoring with a BIS A‐2000 monitor to gauge anesthetic depth in a patient with CIPA. Initial forehead bispectral index (BIS) values prior to induction were normal (98) and then ranged between 23 and 79 during the whole surgical procedure. Propofol and lidocaine were used for induction and deep extubation; isoflurane was used as the sole anesthetic for maintenance with concentrations ranging from 0.21% to 0.92% to maintain a target BIS of 40–60. Volatile anesthetic requirements remained low throughout the procedure and no narcotics were necessary during surgery. The BIS monitor served as an adequate tool to help avoid excessive use of volatile anesthetic while assuring a processed EEG consistent with unconsciousness and amnesia. After the patient had recovered and was oriented to place and time in the recovery room, he was asked whether he remembered anything about the surgery and the presence of a breathing tube in his mouth. He denied any recall of such events.
The moderating effects of service and ambience on customer satisfaction in a fast-casual restaurant: a German case study

In recent years, fast-casual has evolved to become the fastest growing segment within the restaurant industry. This type of restaurant combines the upscale decor of a casual restaurant with elements of a fast service restaurant. The author proposes a conceptual model that investigates the relationship between service quality, food quality, and ambience quality, as well as the interaction of food quality with service quality, ambience quality, and customer satisfaction in a fast-casual restaurant setting. The results of the empirical research indicate that the service quality dimensions influence customer satisfaction and that service quality negatively moderates the link between food quality and customer satisfaction.
Semi-Autonomous Rule Acquisition Framework using Controlled Language and Ontology

Temporary corrosion protection for fresh metal surfaces may be obtained by depositing a thin film of a protective organic compound, particularly a fatty acid ester, from a solvent, preferably a fluorocarbon on the surface to be protected. The film-forming esters are chosen to be self-removing by evaporation so that no cleaning is needed before carrying out processes which require a clean metal surface.
Spread of change in business networks: an empirical study of mergers and acquisitions in the graphic industry

This paper investigates the spread of change in business networks with focus on critical events as triggers of radical change. The conceptual discussion is based on the analytical framework for change developed by Halinen, Salmi and Havila. This framework, compiling the mechanism, nature and forces of change in business networks, distinguishes between confined and connected change. It is suggested that mergers and acquisitions (M&As) may cause changes that spread in the business networks, and M&As are investigated as triggers of radical network change in particular. The paper includes an empirical analysis of M&As in the Nordic graphic industry.
Exploring Art Film Audiences: A Marketing Analysis

The question of whether art film lovers have different movie consumption patterns than commercial film audiences is examined in this study. Art film audiences are found to warrant marketing attention because they are more committed to movie attendance, have a more favorable attitude towards movies in general, and are more tolerant towards movie theater conditions than commercial film audiences.
Exporting as a Means of Growth for Women-owned Canadian SMEs

Abstract This study presents a profile of Canadian women-owned SME exporters and explores motives, challenges, export strategies and gender-related export issues that face women business owners. The results suggest that a majority of women exporters believe that gender plays a role in the operation and/or internationalization of their firm. Gender-specific barriers that may impede export activity included cultural and personal factors such as perceived lack of respect by male business owners, bravado, chauvinism, not being taken seriously, businessmen who refuse to do business with a woman, and verification of decisions through male employees. The findings form the basis of recommendations for further research and program review for government policy makers and practitioners.
Illegal leisure revisited. Changing patterns of alcohol and drug use

on landscape (cowboy art), slow food, and ecotourism as slow development as exemplars of critical pedagogy, related to social and environmental justice. However, it was McClean’s chapter ‘Virtue Ethics: An Emerging Discourse in Social and Environmental Justice Inquiry’, which responded to the central aspect of the book of social and environmental justice, in their ethical inquiry and critique of virtue ethics. The book could have beenmore clearly structured, with an explicit indication of the significance of dividing the book into four parts. The overarching themes in the four parts of the book were not accompanied by detail of how these themes related to the continuity of chapter content and purpose. Likewise, at the end of each of part was a synthesis, which tenuously drew together collective insights from the different chapters. Further, without an overall summary or synthesis at the end of the book, an opportunity was lost to draw together collective informative insights on the epistemology of social and environmental justice. More might have been made of sustainability, covered in some chapters, as a key theme to underpin discussion within the book. This book will be of interest to undergraduate and postgraduate students and will also have some relevance to professionals working in leisure and specifically the parks and open spaces services, in North America. There was a self-contained and eclectic feel to chapter content, in responding to the overall purpose of the book. What emerged as concluding elements of the Symposium and how the book mirrored the outcomes of the Symposium, was understated, with the editors stating that ‘it captured much of the symposium’s content’. With the 19 chapters, at times, moving beyond the context of Parks and Recreation, the book had an experimental feel to its intended purpose. It was difficult to navigate clearly through the book, with no sense of a sequential and consistent approach to advancing the central themes of social and environmental justice. Nevertheless, it was a fascinating read and is a useful resource on aspects of social and environmental justice within leisure.
Optically driven spin nutations in the ground state of atomic sodium.

We report detailed studies of the dynamic response of spin coherence to a step input of optically resonant narrow-band laser radiation in the presence of a static transverse magnetic field. The evolution of the spins is observed with a cw optical probe beam using polarization-selective detection of the transmitted light. In extension of previous optical-pumping experiments, the dynamics of the system are studied systematically as a function of optical-resonance detuning and intensity. Our experiments are performed on the 3s $^{2}S_{1/2}$ ground state of sodium, using the ${D}_{1}$ line for optical excitation. The experimental data are compared with theoretical predictions based on a Bloch-type equation of motion for an optically driven spin system in a J=(1/2 ground state.
Interleaved-contact electroabsorption modulator using doping-selective electrodes with 25 degrees C to 95 degrees C operating range

A multiple-quantum-well (MQW) modulator with multiple stacked p-i(MQW)-n-i(MQW)-p-regions is demonstrated. Electrodes are deposited such that all the n-layers are connected to one contact and all the p-layers to the other. This allows high fields to be produced in the i-regions with relatively low voltages, since the i-regions may be made thin while retaining large optical interaction because they are stacked. A large usable wavelength range which translates into a large operating temperature range is obtained because of large Stark shifts in the MQWs at high fields. For a 0 to 6 V swing >22% reflectivity change from 25 degrees C to 95 degrees C, or alternatively over a wavelength range of 15 nm at 25 degrees C, is achieved. <<ETX>>
Personalized recommendation schemes for DTV channel selectors

The emergence of new TV media such as digital cable and satellite has diversified TV contents. This makes the task of finding one's favorite contents among hundreds of TV channels a time consuming job. To relieve this channel selection overhead, this paper presents personalized recommendation schemes for DTV channel selectors. The proposed recommendation schemes analyze each person's previous watching behavior in terms of recency and frequency, and then utilize this information in the control of the top-down channel selector. Simulation studies show that the proposed schemes reduce the seek cost of the DTV channel selector by up to 62.8% for the trace set we considered
A Study on Bank Debt,Commercial Credit and Corporate Investment Behavior Based on Evidence of China′s Manufacturing Listed Companies

This study empirically examines the relationship among bank debt,commercial credit and corporate investment behavior using panel data from 1999 to 2005 of China′s manufacturing listed companies.The results show that,as a whole,bank debt and commercial credit are negatively related to investment,and this negative effect between bank debt and investment is significantly stronger than between commercial credit and investment.After the interactive term is included in the model and the samples are divided according to IOS,it is disclosed that compared to the firms with low growth opportunities,the negative effect between commercial credit and investment is stronger than the firms with high growth opportunities.But the difference in the negative effect of bank debt on investment decision between the firms with high and low growth opportunities is not significant.
Technical Improvements on Mobile App Based Taxi Dispatching System

Current prevalent mobile apps on taxi dispatching help drivers and passengers find each other, which improves the efficiency of booking a taxi compared to traditional mode. However, there are still some critical issues remained or newly introduced, especially on accuracy, equality, safety and honesty. This paper proposes several technical improvements to solve them. What's more, by exploiting more location and other information from the driver and passenger, some additional improvements on route, taximeter and taxi pooling are discussed.
Hybrid topologies for series and shunt compensation of the line-commutated converter

This paper presents two concepts for enabling the operation of a line-commutated converter (LCC) at leading power angles. The concepts are based on voltage or current injection at the ac side of an LCC, which can be achieved in different ways. However, this paper focuses on the voltage and current injection by series-connected full-bridge cells that can generate voltages that approximate ideal sinusoids. Thus, hybrid configurations of an LCC connected at the ac side in series or in parallel with full-bridge cells are presented. Finally, these hybrid configurations are compared in terms of voltage and current rating.
Resource gaps and resource orchestration shortfalls in supply chain management: : the case of product recalls

type="main" xml:id="jscm12047-abs-0001"> Product recalls are often painful to endure, but they also create important opportunities for learning. Although past research implicitly treats recalls as monolithic, our grounded theory investigation uncovered four types of recalls. Each type of recall provides insight about the adequacy of a firm's resource endowments and how a firm orchestrates the activities around its resources. For researchers, our study highlights the value of examining the confluence of recalls, resource gaps, and resource orchestration shortfalls to better understand the role of resources within supply chain management. For managers, our study highlights the value of knowing what type of recall a firm is facing and how to remedy the problems that led to the recall.
Health and the demand for food in Scotland: economic and demographic effects

Scotland has one of the worst records in the western world for Coronary Heart Disease. The problem is to a large extent diet‐related. The Scottish Office has, therefore, set out a diet plan for Scotland. Its recommendations to the public are in terms of individual foodstuffs. This study using national household survey data and demand modelling based on the Almost Ideal Demand System (AIDS) analyses the economic and demographic factors influencing Scotland’s diet. The analysis shows that Scots are slowly moving from a diet rich in fat and cholesterol to a more healthy diet containing more white meat and fruit and vegetables. Part of the problem is income‐related with the wealthiest segment of the population having the best diet. Age is also a factor with the older people consuming a diet more suitable to the period of heavy industrial labour in which they were brought up.
A magnetic fluid microdevice using insect wings

A magnetic fluid microdevice using Diptera insect wings is proposed and constructed. The magnetic fluid device is composed of insect wings, a small permanent magnet, coil, and kerosene-based magnetic fluid. First, the structural properties of insect wings are studied through measurements of certain morphological parameters. Secondly, the novel type of microwind energy converter is constructed. Thirdly, the power generation characteristics of the magnetic fluid microdevice using insect wings are examined. It is found that the output power is roughly proportional to the cube of the airflow velocity.
NKR-P1A is a target-specific receptor that activates natural killer cell cytotoxicity

NKR-P1A is a lectinlike surface molecule expressed on rat natural killer (NK) cells. NKR-P1A has structural and functional features of an activating NK cell receptor, but a requirement for NKR-P1A in target cell lysis has not been determined. To define the role of NKR-P1A in natural killing, we have generated a mutant of the rat NK cell line, RNK-16, lacking expression of all members of the NKR-P1 receptor family. Although these NKR-P1-deficient NK cells were able to kill many standard tumor targets, including YAC-1, they were selectively deficient in the lysis of IC-21 macrophage, B-16 melanoma, and C1498 lymphoma targets. Reexpression of a single member of the NKR-P1 family, NKR-P1A, on mutant cells restored lysis of IC-21, and killing of IC-21 targets through rat NKR-P1A was completely blocked by F(ab')2 anti-NKR- P1A. Reexpression of NKR-P1A also restored transmembrane signaling to IC-21, as assessed by the generation of inositol-1,4,5-trisphosphate. The generation of inositol-1,4,5-trisphosphate was also restored in response to B-16 targets, but both B-16 and C1498 cells remained resistant to lysis, indicating that other NK cell molecules, perhaps within the NKR-P1 family, are required for the efficient killing of these tumors. These results are the first to demonstrate that NKR-P1A is a target-specific receptor that activates natural killing.
