Infectious Disease Surveillance in the 21st Century: An Integrated Web-Based Surveillance and Case Management System

The Massachusetts Virtual Epidemiologic Network (MAVEN) was deployed in 2006 by the Massachusetts Department of Public Health, Bureau of Infectious Disease to serve as an integrated, Web-based disease surveillance and case management system. MAVEN replaced program-specific, siloed databases, which were inaccessible to local public health and unable to integrate electronic reporting. Disease events are automatically created without human intervention when a case or laboratory report is received and triaged in real time to state and local public health personnel. Events move through workflows for initial notification, case investigation, and case management. Initial development was completed within 12 months and recent state regulations mandate the use of MAVEN by all 351 jurisdictions. More than 300 local boards of health are using MAVEN, there are approximately one million events, and 70 laboratories report electronically. MAVEN has demonstrated responsiveness and flexibility to emerging diseases while also streamlining routine surveillance processes and improving timeliness of notifications and data completeness, although the long-term resource requirements are significant.
Social Protection in Latin America: Achievements and Limitations

Social protection systems in Latin America have been transformed in the past two decades. Until the 1980s, those who were not covered by the social security arrangements available primarily in the urban formal sector received little public assistance beyond universal subsidies for some food or fuel purchases. Since the 1990s, the introduction of non-contributory social insurance programs (including"social pensions") and conditional cash transfers has substantially extended the coverage and improved the incidence of social assistance. However, the organic growth of subsidized social assistance in parallel to the older social insurance system, financed largely out of taxes on formal sector employment, has led to a dual system that is neither properly equitable nor efficient. The twin challenges that now face social protection in Latin America are to better integrate those two halves of the system, and to develop programs that promote sustainable self-reliance, by moving from"safety nets"to"opportunity ropes.

IGARCH effects: an interpretation

This article shows how IGARCH effects can arise as an artifact of unaccounted structural change. Using daily returns for the DM/US$ and Yen/US$ exchange rates, the finding is shown to have empirical relevance. GARCH models appear to be useful approximations, for short-term forecasting, to a data generating process that shows time varying conditional variance due to switching heteroscedasticity.
DarkRank: Accelerating Deep Metric Learning via Cross Sample Similarities Transfer

We have witnessed rapid evolution of deep neural network architecture design in the past years. These latest progresses greatly facilitate the developments in various areas such as computer vision and natural language processing. However, along with the extraordinary performance, these state-of-the-art models also bring in expensive computational cost. Directly deploying these models into applications with real-time requirement is still infeasible. Recently, Hinton et al. have shown that the dark knowledge within a powerful teacher model can significantly help the training of a smaller and faster student network. These knowledge are vastly beneficial to improve the generalization ability of the student model. Inspired by their work, we introduce a new type of knowledge---cross sample similarities for model compression and acceleration. This knowledge can be naturally derived from deep metric learning model. To transfer them, we bring the "learning to rank" technique into deep metric learning formulation. We test our proposed DarkRank method on various metric learning tasks including pedestrian re-identification, image retrieval and image clustering. The results are quite encouraging. Our method can improve over the baseline method by a large margin. Moreover, it is fully compatible with other existing methods. When combined, the performance can be further boosted.
INTERTEMPORAL NONSEPARABILITY OR BORROWING RESTRICTIONS? A DISAGGREGATE ANALYSIS USING A U.S. CONSUMPTION PANEL

We propose a method to test for liquidity constraints which relies on using the within period marginal rate of substitution condition as a benchmark to evaluate the intertemporal Euler equation. If spot markets for nondurable goods exist, but financial markets either do not exist, or are imperfect, we show how the comparison of first order conditions involving the relevant spot and intertemporal prices can be used to detect the imperfection. We apply our methodology to a large sample of U.S. households, drawn from twelve years of the Consumer Expenditure Survey, allowing for a general nonseparable preference structure. Our estimates of first order conditions do not indicate the presence of liquidity constraints, with the possible exception of young households.
A Theory of Noise Trading in Securities Markets

In a recent article, F. Black introduces the concept of noise trading, defin ed as trading on noise as if it were information. He asserts that suc h trading must be a significant factor in securities markets, but doe s not explain why investors would rationally trade on noise. The goal of this paper is to provide such an explanation for one type of inve stor, managers of investment funds. As shown here, the incentive to e ngage in noise trading arises because of the positive signal that the manager's trading level provides about his or her ability to collect private information about security investments.

Identification and Characterization of H2N3 Avian Influenza Virus from Backyard Poultry and Comparison with Novel H2N3 Swine Influenza Virus

SUMMARY. In early 2007, H2N3 influenza virus was isolated from a duck and a chicken in two separate poultry flocks in Ohio. Since the same subtype influenza virus with hemagglutinin (H) and neuraminidase (N) genes of avian lineage was also identified in a swine herd in Missouri in 2006, the objective of this study was to characterize and compare the genetic, antigenic, and biologic properties of the avian and swine isolates. Avian isolates were low pathogenic by in vivo chicken pathogenicity testing. Sequencing and phylogenetic analyses revealed that all genes of the avian isolates were comprised of avian lineages, whereas the swine isolates contained contemporary swine internal gene segments, demonstrating that the avian H2N3 viruses were not directly derived from the swine virus. Sequence comparisons for the H and N genes demonstrated that the avian isolates were similar but not identical to the swine isolates. Accordingly, the avian and swine isolates were also antigenically related as determined by hemagglutination-inhibition (HI) and virus neutralization assays, suggesting that both avian and swine isolates originated from the same group of H2N3 avian influenza viruses. Although serological surveys using the HI assay on poultry flocks and swine herds in Ohio did not reveal further spread of H2 virus from the index flocks, surveillance is important to ensure the virus is not reintroduced to domestic swine or poultry. Contemporary H2N3 avian influenza viruses appear to be easily adaptable to unnatural hosts such as poultry and swine, raising concern regarding the potential for interspecies transmission of avian viruses to humans.
Atimia: A New Paradigm for Investigating How Individuals Feel When Ostracizing Others

ABSTRACT To date, researchers studying ostracism (being excluded and ignored) focused on examining the consequences of ostracism. However, researchers have not yet systematically investigated why individuals ostracize others. One impediment to this research is lacking multiple means to successfully induce individuals to be sources, those who ostracize others. Using Cyberball, researchers found participants ostracized a player delaying the game. To aid in systematic research on sources, we developed the game Atimia. In Atimia, players took turns solving remote associate word items and we varied the performance of a computer-controlled player to perform equal to or significantly worse than the group. Without prompting, participants ostracized a poor- versus equal-performing player more and found the poor-performing player burdensome, less likable, and less desirable to work with on a future task. Study outcomes suggest Atimia is a viable paradigm for investigating sources of ostracism.
British Engineering and the New Zealand Market, 1945-60

Britain's lack-lustre industrial performance after the Second World War is seen through the mirror of an important external market, New Zealand. The spotlight is on the failure of British exporters of diesel electric locomotives and heavy electrical plant to make the most of apparently excellent opportunities in New Zealand between 1945 and 1960. British firms occupied dominant positions in the relevant segments of the New Zealand market in the early post-war period, but frittered their advantage away. Development and production expertise was in limited supply, and was spread too thinly. Cartel pricing alienated public sector customers in New Zealand and encouraged them to give orders to other countries. While these are not novel charges to lay against British manufacturers, there is considerable value in having them confirmed by evidence from a peripheral market that has been relatively neglected by business historians.
Ecological properties of soil water and effects on forest vegetation in the Loess Plateau

In the Loess Plateau of China, soil water has three ecological properties: high infiltration capacity, high storage capacity and availability to deep plant roots. Soil desiccation is the most serious problem for forest vegetation in the Loess Plateau. Arid soils are the result of intensified soil desiccation caused by disturbances in plant succession, which constitute the ecological foundation of soil water. The negative effects of the arid soil layer on surface water infiltration for recharging underground water are discussed in terms of ecological hydrology. The arid soil layer disrupts the link between surface water and underground water and prevents vertical precipitation infiltration from supplementing underground water. Forest vegetation has a significant runoff-retaining efficiency that reduces total runoff from forest areas leading to low surface and ground runoff which affect the water cycle on a watershed scale.
A current update on the phytopharmacological aspects of Houttuynia cordata Thunb

The present review is an attempt to put an insight into a medicinal plant Houttuynia cordata Thunb, which is indigenous to North-East India and China. It is an aromatic medicinal herb belonging to family Saururaceae and is restricted to specialized moist habitats. The review provides detailed information regarding the morphology, distribution, phytochemistry, ethnopharmacological uses and also describes various pharmacological activities reported on the plant H. cordata. The review describes therapeutic efficacy of the whole plant and its extracts, fractions and isolated compounds in different diseased condition. Among the important pharmacological activities reported includes, anti-mutagenic, anti-cancer, adjuvanticity, anti-obesity, hepatoprotective, anti-viral, anti-bacterial, anti-inflammatory, free radical scavenging, anti-microbial, anti-allergic, anti-leukemic, chronic sinusitis and nasal polyps activities. Thus, the present review will act as a source of referential information to researchers to perform clinical studies on isolated compounds that may serve the society and will help in improving human health care system.
Crossing the Valley of Death—An Integrated Framework and a Value Chain for Emerging Technologies

The paper develops an integrated technology-push and market-pull framework, a value chain model for crossing the valley of death (VOD—the gap between laboratory and market) for emerging technologies based on primary and secondary data analyses, and a survey conducted on European research and development projects. The study uses a case of micro- and nano-manufacturing technology (MNT), and confirms the existence of the VOD through the survey data analysis. A mixed-methods approach was adopted that investigated the business and technical challenges to the commercialization of MNT. A notable finding is that the emerging MNT often does not have a direct link with market demand, and the result suggests that an intermediary role between advanced technology and market demand should be integrated to act as a co-ordinator for overcoming the VOD. The paper also examines how an intermediary is crucial to escape the VOD within the value chain of the interdependent relationships between actors.
Selective Estrogen Receptor Modulator Effects of Epimedium Extracts on Breast Cancer and Uterine Growth in Nude Mice

Abstract Epimedium is popularly used in traditional Chinese medicine to treat sexual dysfunction, menstrual irregularity, and osteoporosis. The estrogenic effects of the prenylated flavonoids of Epimedium make it an attractive alternative for hormone replacement therapy. Here, we examined the therapeutic potential of the estrogenic herb extract of Epimedium brevicornum as an alternative to hormone replacement therapy in a breast cancer mouse model. To that end, athymic and ovariectomized female nude mice were subcutaneously injected into the mammary fat pads with MCF-7 breast cancer cells, randomly grouped and fed with soy-free feeds, alone or in combination with ethinyl estradiol or different doses of the estrogenic herb extract of E. brevicornum. Our findings demonstrate that unlike ethinyl estradiol, it did not promote the growth of breast cancer xenograft volume and weight, with the highest dose showing a significant reduction in growth and ERα protein content. Moreover, the extract increased uterine weight at the lowest dose, while higher doses had no effects. Put together, our data shows for the first time that despite the estrogenic activity of E. brevicornum, its action is largely tissue specific and dose-dependent. Our data on E. brevicornum presents in vivo evidence for its selective estrogen receptor modulator effect and warrants exploration of its use as an alternative to hormone replacement therapy in menopausal women.
Determinants of Customer Satisfaction in the Hotel Industry: An Application of Online Review Analysis

This study illustrates that determinants of customer satisfaction in hospitality venues can be identified through an analysis of online reviews. Using text mining and content analysis of 42,668 online traveler reviews covering 774 star-rated hotels, the study found that transportation convenience, food and beverage management, convenience to tourist destinations and value for money are identified as excellent factors that customers booking both luxury and budget hotels consider important and for which the performance is much satisfactory to them. Customers paid more attention to, but were less satisfied with, bed, reception services and room size and decoration. Most determinants of customer satisfaction also showed a consensus over luxury versus budget hotels, except for factors referring to lobby and sound insulation. As per its findings, the article concludes by presenting theoretical and managerial implications.
Training and Occupational Choice

A mine roof support comprises a support member adapted to rest on the floor of a mine gallery, a first shield projecting upwardly from the rear end of the support member, a second shield pivotally attached at its lower end to the upper end of the first shield, an expandable and contractable prop between the support member and the second shield for changing the inclination of the latter and a cap adapted to engage the roof of the mine gallery pivotally attached between its ends to the upper end of the second shield to form between the upper surface of the latter and the bottom face of the cap a wedge-shaped space directed away from the face of the mine gallery. The mine roof support further includes an arrangement for preventing loose rock material from penetrating into this space and comprising a rugged flexible web attached at one end to the upper face of the second shield and extending over a guide roll journalled in bearing on the rear end of the cap along the bottom face toward the front end of the latter, and an arrangement mounted in the region of the front end of the cap and operative for maintaining the web in taut condition.
Exploring the Social Dynamics of Proenvironmental Behavior Change

This article explores the intrinsic role of context in shaping the course and outcomes of interventions aimed at changing environmentally significant behavior in home and workplace settings. Drawing on sociological theories of symbolic interactionism, we evaluate the social dynamics and mechanisms of two similar, team‐based behavior change interventions at work (Environment Champions) and at home (EcoTeams). The analysis shows that the interventions open up different levels of opportunity for reviewing and renegotiating new environmentally friendly behaviors against the reactions and expectations of the immediate peer group, existing workplace or domestic roles, and the situation‐specific definitions of what counts as appropriate behavior in the home and the workplace. We argue that policy studies should pay greater attention to the processes of behavior change, or the contextually sensitive relationship between interventions and outcomes, as a step toward refining or streamlining interventions aimed at changing environmentally significant behavior.
Motor unit recruitment and discharge behavior in movements and isometric contractions

The purpose of this study was to contrast the discharge patterns of the same motor units during movements and during isometric contractions that were produced with comparable torque‐time characteristics. Subjects performed elbow flexion and extension movements with predetermined acceleration characteristics. The average acceleration and deceleration profiles for the movements were reproduced in the isometric setting by presenting the kinematic profiles as templates for torque production. Trained subjects were able to match the first agonist (AG1) and antagonist (ANT) electromyographic (EMG) bursts, but tended to produce a smaller second agonist burst (AG2) in the isometric contraction. Twenty‐five motor units from triceps brachii were studied. The same motor units (with one exception) were recruited and subsequently discharged in a similar fashion in both the isometric and movement tasks in the AG1 and ANT EMG bursts, with fewer motor unit discharges in the AG2 burst in the isometric contraction. The central control mechanisms appear to be the same for the acceleration phase of movement and isometric contraction, but differ during the deceleration phase. © 1997 John Wiley & Sons, Inc.

Shareholders’ Agreement as a Tool to Mitigate Corporate Conflicts of Interests

Legal discussions in the context of corporate governance have for some time been dominated by the agency problems and possible legal solutions and strategies to solve them. However, little attention has been paid to the contractual means (including shareholders’ agreements) to regulate relationships among shareholders and their relations with other corporate constituents. The aim of this paper is to show that shareholders’ agreements can be used to mitigate some of the conflicts in the corporate governance field. The concept of the shareholders’ agreement as well as a brief discussion on the comparative aspects of legal regulation in the Republic of Lithuania, the Kingdom of Belgium and the UK is provided in the article. Empirical data on the availability of shareholders’ agreements in the publicly listed companies in the selected jurisdictions is also presented.
Offshoring, Globalization and Welfare

We investigate the issue of offshoring in a general-equilibrium model of two countries and one sector of increasing returns to scale. Our model uncovers that offshoring occurs and endogenously evolves in a bell-shaped pattern when trade costs decline, explaining some stylized facts in developed countries. Furthermore, this simple framework can be applied to examine the welfare issue. We find that a fall in offshoring costs benefits the high-wage country but hurts the low-wage country. On the other hand, the low-wage country benefits with trade liberalization. The impact of falling trade costs on the welfare of the high-wage country depends on the values of offshoring freeness.
The School Head as an Instructional Leader in Zimbabwe Secondary Schools

This paper presents evidence obtained from a survey of secondary school heads in government schools, church schools, and rural day schools about functions performed by those heads, characteristics of secondary school heads and problems constraining heads from discharging their duties effectively and efficiently. The evidence shows that: 1. The majority of rural secondary schools are administered by inexperienced and lowly qualified and untrained heads who also' have heavy teaching loads. 2. The majority of school heads possess minimal or no knowledge in technical subjects, a situation which appears not supportive of the implementation of the policy of vocationalization of secondary school education. 3. While the thrust in secondary school education is on technical education, school heads do not consider the training of students in technical fields as a top priority for secondary schools. To the contrary, heads consider character building and preparation for post-secondary programmes as top priorities for secondary schools. 4. Secondary school heads devote most of their time on administrative duties thereby neglecting the critical activities in the curriculum and instructional domains.
Real Effects of High Inflation

This paper revisits the question of the real effects of inflation, on the basis of the experience with 23 high inflation episodes in 17 countries. It finds strong indications that inflation had contractionary effects on a number of important macroeconomic variables, such as GDP, investment and employment. Moreover, high inflation led to a significant decline in real wages, a real depreciation and an improvement in external trade. These patterns are consistent with explanations that stress the transaction role of money, such as models with a cash-in-advance constraint. However, some observations are hard to reconcile with existing theory, especially the large magnitude of the fall in real wages.
Heterogeneous Belief and Seemingly Emotional Market Behavior

Taking account of both asymmetric information and rational learning, we show that heterogeneous belief in a rational expectation model can explain many empirical findings of seemingly emotional behavior in stock market, such as bubbles, momentum, contrarian, and technical trading. We show that momentum and contrarian price movements can coexist in an asset market with only rational agents. A random shock in a firm's intrinsic value can lead to a momentum price movement followed by a contrarian price movement. The duration and magnitude of momentum and contrarian price movement are associated with trading volume. Rational investors would incorporate price and volume information in their trading decision. Our theory seems to provide a coherent explanation to a long list of controversial and seemingly contradictory empirical findings.
