Handel recovering: fresh light on his affairs in 1737

The summer and autumn of 1737 remain a foggy patch in Handel biography owing to poor documentation and Handel’s absence from London. We do not know whether his illness led to a rapprochement with the ‘Nobility’ opera, how his visit to Aix-la-Chapel complicated the new opera season or, especially, whether these developments relate to Farinelli’s defection to Spain. This shaky factual ground also restricts our understanding of later events such as Handel’s lucrative benefit in March 1738 and the celebrated Roubiliac statue in Vauxhall Gardens. Thanks to surviving issues of the Daily Advertiser, however, we now can replenish the documentary pool and re-examine Handel’s affairs and their context during this period

An Optimization Model for Single-Warehouse Multi-Agents Distribution Network Problems under Varying of Transportation Facilities: A Case Study

The transportation cost of goods is the highest day-to-day operational cost associated with the food industry sector. A company may be able to reduce logistics cost and simultaneously improve service level by optimizing of distribution network. In reality, a company faces problems considering capacitated transportation facilities and time constraint of delivery. In this paper, we develop a new model of order fulfillment physical distribution to minimize transportation cost under limited of transportation facilities. The first step is defined problem description. After that, we formulate a integer linear programming model for the single-warehouse, multiple-agents considering varying of transportation facilities in multi-period shipment planning. We analyze problems faced by company when should decide policy of distribution due to varying of transportation facilities in volume, type of vehicle, delivery cost, lead time and ownership of facilities. We assumed transportation costs are modeled with a linear term in the objective function. Then, we solve the model with Microsoft Excel Solver 8.0 Version. Finally, we analyze the results with considering amount of transportation facilities, volume usage and total transportation cost. Keywords: physical distribution, shipment planning, integer linear programming, transportation cost, transportation facilities

Does mood affect trading behavior?

We test whether investor mood affects trading with data on all stock market transactions in Finland, utilizing variation in daylight and local weather. We find some evidence that environmental mood variables (local weather, length of day, daylight saving and lunar phase) affect investors’ direction of trade and volume. The effect magnitudes are roughly comparable to those of classical seasonals, such as the Monday effect. The statistical significance of the mood variables is weak in many cases, however. Only very little of the day-to-day variation in trading is collectively explained by all mood variables and calendar effects, but lower frequency variation seems connected to holiday seasons

Visual Detection of Structural Changes in Time-Varying Graphs Using Persistent Homology

Topological data analysis is an emerging area in exploratory data analysis and data mining. Its main tool, persistent homology, has become a popular technique to study the structure of complex, high-dimensional data. In this paper, we propose a novel method using persistent homology to quantify structural changes in time-varying graphs. Specifically, we transform each instance of the time-varying graph into metric spaces, extract topological features using persistent homology, and compare those features over time. We provide a visualization that assists in time-varying graph exploration and helps to identify patterns of behavior within the data. To validate our approach, we conduct several case studies on real world data sets and show how our method can find cyclic patterns, deviations from those patterns, and one-time events in time-varying graphs. We also examine whether persistence-based similarity measure as a graph metric satisfies a set of well-established, desirable properties for graph metrics

Typological Classification of the Cyrillic Manuscripts and Early Printed Books with the Gospel Texts

The paper presents the rules for typological classification of Slavonic manuscripts and early printed books with the Gospel text. It enumerates different types of the books with the Gospel and sometimes also with other parts of the Holy Scripture. Information about the Greek tradition of the Gospel is also included in the article and serves as the basis of comparison

Black Power At Work: Community Control, Affirmative Action, and the Construction Industry

{Excerpt} As the contributors to this book show, confrontations with the building trades unions became a critical axis for the rise of Black Power and community control politics, and provide a means for us to rethink the history of Black Power through the fusion by the movement of community control and labor organizing. By tracing the evolution of these activists\u27 organizing methods and analysis, we show that African American grassroots struggles to desegregate the construction industry provided a major, and in some cities the, means through which Black Power movements became ascendant in African American urban politics. Only through close attention to local politics are these profound cultural and political shifts visible. Because of their decentralized quality, the movements for community control of the construction industry varied by city, based on the idiosyncratic nature of the specific African American communities and political networks from which they emerged. These differences were accentuated by weak federal enforcement of affirmative action plans, which relied on a strategy of localism that placed the origin, evolution, and fate of construction industry affirmative action plans primarily in the hands of local actors and courts
