We have observed the nearly face-on spiral galaxy NGC 5668 with the TAURUS II Fabry-Perot interferometer at the William Herschel Telescope using the Hα line to study the kinematics of the ionized gas. From the extracted data cube we construct intensity, velocity and velocity dispersion maps. We calculate the rotation curve in the innermost 2 arcmin and we use the residual velocity field to look...

Hotel managers continue to find ways to understand traveler preferences, with the aim of improving their strategic planning, marketing, and product development. Traveler preference is unpredictable; for example, hotel guests used to prefer having a telephone in the room, but now favor fast Internet connection. Changes in preference influence the performance of hotel businesses, thus creating th...

Today’s economy is characterized by increased competition, faster product development and increased product differentiation. As a consequence product lifecycles become shorter and demand patterns become more volatile which especially affects the retail industry. This new situation imposes stronger requirements on demand forecasting methods. Due to shorter product lifecycles historical sales inf...

This paper analyses the influence of the capital market on the labour market. Especially the impact of start-up financing on the structure of unemployment is of interest. We use a crosscountry panel data analysis to examine how venture capital investment influences disaggregate unemployment. As we expected, venture capital investment has different influences on sectoral-, educationaland occupat...

In this paper we present the first BV I CCD photometry of six overlooked old open clusters (Berkeley 44, NGC 6827, Berkeley 52, Berkeley 56, Skiff 1 and Berkeley 5) and derive estimates of their fundamental parameters by using isochrones from the Padova library (Girardi et al. 2000). We found that all the clusters are older than the Hyades, with ages ranging from 0.8 (NGC 6827 and Berkeley 5) t...

To analyze the big data on web or so, a new type teaching methods of linear algebra is required. In the paper, three requirements for the new teaching method are discussed. They are realated to (1) Vectornotation based expression transformation, (2) eigenvalues of a variance-covariance matrix, and (3) visualization of multivariant analysis.

Outsourcing is fundamental to firm competitiveness. Firms are increasingly externalizing a variety of core business functions such as research and development, product development, and marketing to achieve diverse strategic objectives (Mani et al. 2012, 2013). Yet, despite their extended reach and impact, outsourcing initiatives involve high failure rates with adverse impacts on various critica...

Two recent publications report the emerging technologies that are likely to have a significant impact on learning and instruction: (a) New Media Consortium’s 2011 Horizon Report (Johnson, Smith, Willis, Levine & Haywood, 2011), and (b) A Roadmap for Education Technology funded by the National Science Foundation in the USA (to download the report see http://www.cra.org/ccc/edtech.php). Some of t...

Due to brutal business competition, new product development (NPD) has become a key factor for promoting business sustainability. To help a company determine the direction of NPD for the future, this study applies the fuzzy analytical hierarchy procedure (AHP) and fuzzy data envelopment analysis (DEA) to develop an evaluation and ranking methodology, assisting decision makers to select NPD proje...
