  • A study for the German Ministry of Economics and Technology (Fryges et al, 2007) analysed high- tech start-ups and Business Angels. The results, presented here, are based on analysed companies that have been founded between 2001 and 2005 (formation cohort/group 2001-2005). According to the study, the most important source of financing for the young companies of this formation cohort is cash-flow and owner’s equity. Among newly created high-tech companies of the cohort 2001-2005 in Germany approx. 5% received Business Angel financing (approx 3,700 companies).

  • The quantitative part will start with analysing the shape of the growth pattern of the quantity of cinema consumed and expenditure on cinema. The time of the take-off will be estimated quantitatively (and its timing compared with the qualitative findings above). Also growth rates and quantities time series will be compared across countries. A second quantitative section will analyse family expenditure on entertainment between 1890 and 1940.

  • Two other studies also examine the relation between earnings and the price response to splits; unfortunately, due to methodological differences their results provide no evidence regarding the issue raised by AHP. For example, McNichols and Dravid [19] find that split announcement-period abnormal returns are positively related to analysts' earnings forecast errors observed for the fiscal year-end that follows the announcement. At first glance, this result appears inconsistent with AHP. However, unless one knows the source of analysts' underestimation of post-split earnings, i.e.

  • In this paper, we present a new learning scenario, heterogeneous transfer learning, which improves learning performance when the data can be in different feature spaces and where no correspondence between data instances in these spaces is provided. In the past, we have classified Chinese text documents using English training data under the heterogeneous transfer learning framework. In this paper, we present image clustering as an example to illustrate how unsupervised learning can be improved by transferring knowledge from auxiliary heterogeneous data obtained from the social Web. ...

  • A thermodynamic model for heterogeneous mixtures involving multi-molecular sorption is proposed. Some complex relationships between sorption potential, diffusion, sorption kinetics polymer network change kinetics, chemical affinity energy of internal changes and physico- chemical properties of polymer network are obtained. This model has interpreted some experimental results of fluid sorption in polymer network. Proposed model may be also used for study of other problems in heterogeneous mixture of fluid and polymers.

  • Due to the inconclusive findings and the fact that ambient air pollution levels have declined in most parts of the country while the reported incidence of asthma has risen6 , many researchers have begun to question the link between ambient air pollution and asthma (von Mutius (2000a, 2000b), Vacek (1999), Duhme et. al. (1998)). For example, the Committee on the Medical Effects of Air Pollution concluded that “overall evidence is small that non-biological outdoor air pollution has an important effect on the initiation and [provocation] of asthma” (2000).

  • Traditional Information Extraction (IE) takes a relation name and hand-tagged examples of that relation as input. Open IE is a relationindependent extraction paradigm that is tailored to massive and heterogeneous corpora such as the Web. An Open IE system extracts a diverse set of relational tuples from text without any relation-specific input. How is Open IE possible? We analyze a sample of English sentences to demonstrate that numerous relationships are expressed using a compact set of relation-independent lexico-syntactic patterns, which can be learned by an Open IE system. ...

  • This first part is concerned with processes in which the kinetic behaviour of a gaseous phase is rate-determining. The range of processes includes some which are carried out in vacuum systems in which Knudsen or free evaporation occurs from a condensed phase, to transport reactions where a chemical reaction occurs between a solid and the gaseous phase to produce molecular species containing some or all of the elements occurring in the solid phase.

  • In empirical studies of retirement decisions of the elderly, health is often found to have a large, if not dominant, effect. Depending on which health measures are used, these estimated effects may be biased estimates of the causal effect of health on the dependent variable(s).Research indicates that subjective, self-assessed health measures may be affected by endogenous reporting behaviour and even if an objective health measure is used, it is not likely ...

  • This is probably the slowest and least reliable method to getting consistent results on Google as there may be thousands of sites ahead of your website. Your site is competing with millions of existing sites, and even after submitting your site there is no guarantee Google will list you since this is their least preferred method of finding new sites. While you should not skip this first step, Google would rather discover you on their own. How can you help Google do this? Link to other indexed sites; create good site content; and use popular search terms. ...

  • Despite their significant role in availing financial services to underprivileged groups and communities, the involvement of savings banks in the microfinance’s arena is often overlooked as many are still restricted from lending and offering microcredit schemes. However, these restrictions are progressively lifted, fully or partially, allowing a few to expand the scope of their operations.

  • Key planning considerations for federal agencies include recognizing that the transition is already under way, because IPv6-capable software and equipment already exists in agency networks. Other important agency planning considerations include developing inventories and assessing risks; creating business cases that identify organizational needs and goals; establishing policies and enforcement mechanisms; determining costs; and identifying timelines and methods for transition.

  • The potential benefits of tutoring for pre-service teachers in various content areas are well documented in a number of studies (see, for example, Ryan & Robinson, 1990, Fresko, 1999; Hedrick, 1999). Tutoring can lead to an increased sense of accom- plishment and self-esteem, better mastery of academic skills, increased ability to apply and integrate knowledge taught in different courses and a broader, more real- istic outlook on the process of teaching and learning.

  • Since the mid-1990s, the Indian financial system has been steadily if incrementally deregulated and more exposed to international financial markets. Its rapid transformation has been accompanied by strong economic growth, increased market robustness, and a considerable increase in efficiency. Reforms are continuing with the development of appropriate market regulation and an associated payment and settlement system, as well as greater integration into global financial markets.

  • Variation in precipitation will also affect the salinity levels of surface water. Increased rainfall or runoff will likely reduce salinity levels, especially in winter, while lower precipitation levels and higher temperatures during summertime could increase salinity levels (Jacobs et al. 2001). As a result, semi- arid regions that suffer from decreasing runoff will be greatly impacted by salinization (Jacobs et al. 2001).

  • You may have noticed how each of the deliverables mentioned earlier represents one of two perspectives on the project: business or engineering. On many projects, these two views compete with each other. This is a fundamental planning mistake. Planning should rarely be a binary, or either/or, experience. Instead, it should be an integration and synthesis of what everyone can contribute. To make this happen, a project manager must recognize that each perspective contributes something unique that cannot be replaced by more of something else (i.e.

  • In our conceptual DBMS model, there are many data nodes. The physical data is partitioned among the data nodes in a way that is optimized for the specific DBMS. Once the SQL node has formulated the execution plan, the plan is routed to the data nodes that manage the data partitions targeted by the SQL statement. Each data node performs the execution plan it is given and forms a result set. The result set from each data node is returned to the SQL node, where it is merged with the result set from the other data nodes. The final...

  • While many studies have focused on estimating a relationship between pollution and health, they have largely neglected to consider that pollution exposure is endogenously determined if individuals make choices to maximize their well-being. People with high preferences for clean air may choose to live in areas with better air quality. People can respond to a wide range of readily available information on pollution levels by adjusting their exposure. Failing to appropriately account for such actions can yield misleading estimates of the causal effect of pollution on health. ...
