Entrepreneurship, the new economy and public policy : Schumpeterian perspectives
Silicon Valley is the most salient example of high-tech industrial clusters. Public policy makers throughout the world would like to learn the secrets of Silicon Valley in order to build their own high-tech economies. The existing literature on ind- trial clusters, which traces back to Marshall (1920), focuses on the way in which ?rms bene?t from locating in a cluster; it suggests that once a cluster comes into existence However, a more important question is how to reach this critical mass in the ?rst place. In contrast to the literature, evidence suggests that entrepreneurs rarely move when they est- lish high-tech start-ups. This contradicts the notion that location choice analyses lead entrepreneurs to a high-tech cluster. A high-tech industrial cluster such as Silicon Valley is characterized by c- centrated entrepreneurship.
Enhancing the Dissolution Rate of Atorvastatin by Solid Dispersion Technique
In the last few decades, solid dispersion (SD) technology had been studied as an approach to produce an amorphous carrier to enhance the solubility, dissolution rate, and bioavailability of poorly water-soluble drugs. The use of suitable carrier and methodology in the preparation of SDs play a significant role in the biological behavior of the SDs. Atorvastatin is a statin group HMG-CoA reductase inhibitor drug that is commonly used to adverse cardiovascular events and to lower blood total cholesterol and LDL-cholesterol. the solubility of atorvastatin in water is very low (0.1 mg mL− 1), which results in reduced bioavailability. In order to enhance its solubility, we have prepared solid dispersions (SDs) of atorvastatin at different drug: polymer ratios (1:2, 1:10, 1:20,1:25 and 1:40), using polyethylene glycol 6000 as polymer and different preparation methods (co-precipitate and melting methods) The characterization of the SDs was performed using differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) The solubility of AT was improved by the incorporation PEG6000.

Enabling things to talk : Designing IoT solutions with the IoT architectural reference model
The Internet of Things (IoT) is an emerging network superstructure that will connect physical resources and actual users. It will support an ecosystem of smart applications and services bringing hyper-connectivity to our society by using augmented and rich interfaces. Whereas in the beginning IoT referred to the advent of barcodes and Radio Frequency Identification (RFID), which helped to automate inventory, tracking and basic identification, today IoT is characterized by a dynamic trend toward connecting smart sensors, objects, devices, data and applications. The next step will be “cognitive IoT,” facilitating object and data re-use across application domains and leveraging hyper-connectivity, interoperability solutions and semantically enriched information distribution.
Emerging Organic Pollutants in Waste Waters and Sludge
Over the past fifteen years regulatory agencies have relied on their approaches to characterise and control the release of toxic substances into the aquatic environment: a GC/MS analysis for U.S. EPA designated 126 priority pollutants and 132 dangerous substances according to the European 76/464/CEE Directive and on the bioassays with aquatic bioorganisms. "Emerging Contaminants" correspond in most cases to irregulated contaminants, e.g. surfactants, pharmaceuticals and personal care products (PPCP), or gasoline additives. These two volumes, 5/I and 5/O, of this Handbook deal with the analytical, toxicological and environmental issues of these toxicants. Based on results of up-to-date research they give the reader a balanced view on this rapidly developing and complex subject.
Electronic vs. Floor Based Trading
Historically, specialists and other floor brokers, in direct contact on the trading floor, have been at the heart of operations at the national U.S. equity exchanges. At the other end of the spectrum, electronic trading platforms have characterized most other equity markets globally for many years. Recent developments at the NYSE have moved in this direction, but fundamental questions effecting market quality remain. Can the unique services offered by the floor be provided as effectively in an electronic environment? Which environment would institutional and retail traders each find most suitable to their special needs? Which environment offers better price and quantity discovery? These are some of the questions that are addressed in this book, while providing perspective on the future direction that exchange market structure is likely to follow in the coming years.

Economics of Accounting : Performance Evaluation
This book Performance Evaluation is divided into four parts. Volume I contains Parts A through D, and the concepts developed in Part A are fundamental to both volumes. In Volume II, Part E initially focuses on optimal contracts in a single-agent /single-task/single-period setting, and explores how performance measure characteristics affect the principal’s expected payoff. Multiple performance measures (including the stock price) and multiple tasks are introduced, thereby creating settings in which the principal is concerned with both the level of incentives and the congruency of the incentives with his own preferences. Part F considers the impact of start-of-period private management information (with communication to the principal) and limited commitment in single-period settings. These analyses serve as a bridge to the multi-period models explored in Part G. These multi-period models permit exploration of the impact of inter-period consumption preferences and limited inter-period commitments on preferences with respect to the inter-period correlation and timing of performance reports. Part H concludes the book with an analysis of multi-agent contracting in settings in which agents may coordinate their actions to their mutual benefit, and may even engage in overt collusion.

Eating disorders
What is an Eating Disorder (ED)? Eating disorders are a type of serious mental health condition characterized by severe disturbances in eating behaviors and related to persistent eating behaviors that negatively impact your health, your emotions and your ability to function in important areas of life. Most eating disorders involve focusing too much on your weight, body shape and food, leading to dangerous eating behaviors. These behaviors can significantly impact your body's ability to get appropriate nutrition. Eating disorders can harm the heart, digestive system, bones, and teeth and mouth, and lead to other diseases. Eating disorders affect several million people at any given time, ED often develop in the teen and young adult years, although they can develop at other ages. Eating disorders can affect people of all genders, ages, races, religions, ethnicities, sexual orientations, body shapes, and weights.
