Volatility and correlations for stock markets in the emerging economies of Central and Eastern Europe : implications for European investors

This paper examines the European investment implications of the recent European Union (EU) expansion to encompass former Eastern bloc economies. What are the risk and return characteristics of these markets pre- and post-EU? What are the implications for investors within the Euro zone? Should investors diversify outside the Central and Eastern Europe (CEE)? The former Eastern bloc economies constitute emerging markets which typically offer attractive risk-adjusted returns for international investors. In this paper, we explore a number of aspects of this important issue and their implications for CEE based investors, culminating in a Markowitz efficient frontier analysis of these markets pre- and post-EU expansion

Factors affecting the growth of small privately-owned financial planning businesses

Over the past 10 years, there have been many financial scandals in the financial advice industry, which has caused substantial losses for investors. Large wealth institutions controlled by major Australian banks have significantly contributed to investor losses by promoting their products which were not always in the best interests of clients. The aim of this study was to explore the factors affecting the current and future growth of small privately-owned financial planning businesses as a competitive marketplace provides better consumer outcomes. The study undertook a qualitative approach using an exploratory research design which involved the recruitment of 51 privately-owned financial planning practice owners who were personally interviewed with semi-structured interview questions. Using a theoretical framework based on Michael Porter\u27s five competitive forces model, the study found that the main factors enhancing growth were differentiation of service, technology enhancement, target marketing and business and client referral arrangements. Factors that negatively affected growth included the affordability of providing advice due to regulatory changes and the negative public perception associated with various industry scandals. The results provide existing and new entrant adviser practices with valuable knowledge to make informed decisions in the areas of practice management and direction. Additionally, the study provides policymakers and regulators with further knowledge to better support the privately-owned financial planning sector, thus enabling consumers to benefit from a more competitive marketplace

A Call to Arms: Revisiting Database Design

Good database design is crucial to obtain a sound, consistent database, and - in turn - good database design methodologies are the best way to achieve the right design. These methodologies are taught to most Computer Science undergraduates, as part of any Introduction to Database class. They can be considered part of the "canon", and indeed, the overall approach to database design has been unchanged for years. Moreover, none of the major database research assessments identify database design as a strategic research direction. Should we conclude that database design is a solved problem? Our thesis is that database design remains a critical unsolved problem. Hence, it should be the subject of more research. Our starting point is the observation that traditional database design is not used in practice - and if it were used it would result in designs that are not well adapted to current environments. In short, database design has failed to keep up with the times. In this paper, we put forth arguments to support our viewpoint, analyze the root causes of this situation and suggest some avenues of research.Comment: Removed spurious column break.

Diammonium potassium citrate, (NH4)2KC6H5O7

The crystal structure of di­ammonium potassium citrate, 2NH(4) (+)·K(+)·C(6)H(5)O(7) (3−), has been solved and refined using laboratory X-ray powder diffraction data and optimized using density functional theory. The KO(7) coordination polyhedra are isolated. The ammonium cations and the hydro­phobic methyl­ene sides of the citrate anions occupy the spaces between the coordination polyhedra. Each hydrogen atom of the ammonium ions acts as a donor in a charge-assisted N—H⋯O, N—H⋯(O,O) or N—H⋯(O,O,O) hydrogen bond. There is an intra­molecular O—H⋯O hydrogen bond in the citrate anion between the hydroxide group and one of the terminal carboxyl­ate groups. [Image: see text

Magnetic Properties of TbNi1 xAuxIn Compounds

Polycrystalline samples of $TbNi_{1-x}Au_{x}In$ for x = 0.1, 0.2, 0.4, 0.6 and 0.8 were prepared and studied by powder X-ray and neutron diffraction and ac magnetic susceptibility measurements. These compounds crystallize in the hexagonal ZrNiAl-type structure. With increasing Au content a change in the magnetic structure is observed. For x = 0.1, 0.2 and 0.4 the magnetic order is described by the propagation vector k = (1/2, 0, 1/2) while for x = 0.8 by k = (0, 0, 1/2). Between 1.5 K and the Néel temperature the magnetic order is stable

A wearable headset for monitoring electromyography responses within spinal surgery

Purpose: This research examines an approach for enhancing the efficiency of spinal surgery utilising the technological capabilities and design functionalities of wearable headsets, in this case Google Glass. The aim was to improve the efficiency of the selective dorsal rhizotomy neurosurgical procedure initially through the use of Glass via an innovative approach to information design for an intraoperative monitoring display. Methods Utilising primary and secondary research methods the development of a new electromyography response display for a wearable headset was undertaken. Results: Testing proved that Glass was fit for purpose and that the new intraoperative monitor design provided an example platform for the innovative intraoperative monitoring display; however, alternative wearable headsets such as the Microsoft HoloLens could also be equally viable. Conclusion: The new display design combined with the appropriate wearable technology could greatly benefit the selective dorsal rhizotomy procedure
