The highly specialized processes of modern supply chains, the diverse geographic distribution of suppliers and the complex electronic control systems are posing numerous new threats to companies in a global market environment more competitive than ever before. This article is about the risk-related challenges corporations face today as well as about the methods and practices they should consider applying in order to ensure the continuity of their daily operation and their supply chain in particular. In the introduction we present the current trends and fundamental challenges regarding modern supply chains. In the next chapter we introduce the method of ITBCP as a relatively new, but highly useful tool of managing IT-related operational risk factors and provide a high-level comparison with classic BCP methodologies. The third chapter is about the new challenges companies face in regard to various operational risks, while the fourth chapter briefly describes the most commonly used techniques of identifying and managing these threats. The last chapter serves as a conclusion, a summary why corporations need to take sophisticated preventive measures in order to minimize their risks threatening operational continuity.

How is online social media activity structured in the geographical space? Recent studies have shown that in spite of earlier visions about the "death of distance", physical proximity is still a major factor in social tie formation and maintenance in virtual social networks. Yet, it is unclear, what are the characteristics of the distance dependence in online social networks. In order to explore this issue the complete network of the former major Hungarian online social network is analyzed. We find that the distance dependence is weaker for the online social network ties than what was found earlier for phone communication networks. For a further analysis we introduced a coarser granularity: We identified the settlements with the nodes of a network and assigned two kinds of weights to the links between them. When the weights are proportional to the number of contacts we observed weakly formed, but spatially based modules resemble to the borders of macro-regions, the highest level of regional administration in the country. If the weights are defined relative to an uncorrelated null model, the next level of administrative regions, counties are reflected. © 2015 Lengyel et al.

As a result of financial scandals, fraud has become an important concern over the past decades, which has also raised the issue of independent auditors' responsibilities for detecting fraud. This study examines how auditors perform fraud risk assessment by applying either the traditional or the decomposition methods to different perceived risk level settings. We also investigate how the outcomes of risk assessment influence the audit planning phase. The results prove that the decomposition approach more significantly enhances auditors' sensitivity to fraud cues between a high and low fraud risk condition than using the traditional audit risk model. In addition, the perception of a more enhanced fraud risk leads to higher propensity to consult with forensic experts. Finally, the research also indicates that the assessed fraud risk level has fundamental impact on total hours budgeted for the audit engagement along with internal structure of total hours allocated to the audit.

Hungary is one of a few countries that do not operate either a national, non-profit, or a profit oriented business-based complete mandatory credit information system (i.e., credit register or credit bureau). In its absence, the Hungarian banks have not enough information on their borrowers to evaluate their creditworthiness, to apply behavioural scorings or proper risk management and credit pricing tools. The debate on the necessity of a complete credit information system has almost a decade long history in Hungary. Until now, despite all the professional arguments, the counter arguments from the point of view of personal data protection proved to be stronger. The lack of the complete credit information system became even more painful during the recent financial crisis, when the quality of the retail credit portfolio significantly deteriorated. This paper presents the most important milestones of the institutional history of the struggle for the complete credit information system and analyses the tendencies on the Hungarian retail lending market, with special regard to the lack of it. © Julia Király and Katalin Méro, 2011.

Mutual information in three (or more) dimensions can be considered as a Triple-Helix indicator of possible synergy in university-industry-government relations. An open-source routine th4.exe makes the computation of this indicator interactively available at the internet, and thus applicable to large sets of data. Th4.exe computes all probabilistic entropies and mutual information in two, three, and, if available in the data, four dimensions among, for example, classes such as geographical addresses (cities, regions), technological codes (e.g. OECD's NACE codes), and size categories; or, alternatively, among institutional addresses (academic, industrial, public sector) in document sets. The relations between the Triple-Helix indicator-as an indicator of synergy-and the Triple-Helix model that specifies the possibility of feedback by an overlay of communications, are also discussed. © 2013 Akadémiai Kiadó, Budapest, Hungary.

Using techniques of data collection and mapping as overlays to Google Maps-on the basis of patent information available online at the U.S. Patent and Trademark Office (USPTO)-we point at two major and interconnected challenges that policy-makers face in Central and Eastern Europe (CEE) when combating the lagging innovation performance. First, we address the spatial concentration by using a distribution analysis at the city level. The results suggest that patenting is concentrated in post-socialist territories more than in western nations and regions. However, there is not a single outstanding hub in CEE when one compares USPTO patents normalized for the respective population sizes. Secondly, we argue that dominance of foreign control over USPTO patents is mostly embodied in international co-operations at the individual level, and only rarely spilled-over to MNE subsidiaries. In our opinion, catching-up of CEE in terms of patenting is unlikely, unless innovation policy measures focus on growing hubs and target both domestic inventors and international relations of companies.

Fruit and vegetable consumption plays a multi-level intermediary role in the development of people’s health status and body weight. Even using state-of-the-art methods, it is hard to find unambiguous causality, because it has an especially complex biological and behavioral connection to health. The public burden imposed by illnesses related to low fruit and vegetable consumption is significant, but not the most significant. Definition of the fruit and vegetable categories is not uniform, even though it is always related to their health significance, i.e. their nutrient and fiber contents. National and professional fruit and vegetable consumption recommendations usually follow WHO recommendations, but do not always coincide with the latter. In addition to unfortunate methodological and interpretation difficulties, the goal in this case is to bridge the „attitude-behavior gap”, i.e. conquering the complex problem that people want to act differently from what they actually do. Based on the data of the Household Budget Survey of the Hungarian Central Statistical Office (CSO-HBS), fruit and vegetable categories that are bought in the largest amounts are presented, according to settlement size, value bought, quantity produced, as well as the size of the household. © 2015, Hungarian National Commiteee of the European Organization for quality.
