Multilevel environment analysis is important for companies operating on the global market. Previous studies have in general focused on one level at a time, but the need to perform multilevel environment analysis has also been stressed. Multilevel analysis can partly explain the benchmarking gap between companies, as changing conditions in the upper environment levels affect lower levels. In today's information‐rich era, it is difficult to conduct multilevel analysis without suitable computational tools. This paper illustrates how the self‐organizing map can be used for the simultaneous comparison of industry‐level changes and financial performance of pulp and paper companies. The study shows the importance of simultaneous analysis, as some simultaneous changes were found at both industry and corporate levels. Also found were some industry‐specific explanatory factors for good (Scandinavian companies) and poor (Japanese companies) financial performance. The results indicate that the self‐organizing map could be a suitable tool when the purpose is to visualize large masses of multilevel data from high‐dimensional databases.

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Approaches to state provision of childcare have typically focused on the relative weight of state or market provision. In this article we follow a new institutional approach to the relationship between states and markets to examine the au pair industry, emphasising the role of states in the creation of markets for childcare. Research on the market provision of childcare has focused on the ambiguity in defining caring as work, which has led to the low value of care work. In this article we propose that those ambiguities also exist at the state level and impact the creation of the market for foreign childcare. Examining the development of au pair policies in the US, UK, and Australia, we find three strategies that involve defining au pairs not as employees, but rather as foreign visitors, exchange students, or family members. These strategies allow for by passing restrictions on immigration, increasing the supply of care providers, and circumventing compliance with labour regulations, thereby reducing the cost to families.

The hiring of illegal aliens by any business in the United States can result in more significant consequences because of the Immigration Reform and Control Act of 1986 and the Illegal Immigration Reform and Immigration Responsibility Act of 1996. Both pieces of federal legislation are aimed at placing a bigger burden of responsibility on private employers. The new laws make hiring illegal aliens a federal crime. The resources of the United States can be put behind litigation against violators. By conducting a review of the literature on both these federal acts, along with any other immigration changes in regards to hiring foreign workers, conclusions and recommendations can be drawn to assist and guide a private employer from avoiding hiring illegal aliens.

The purpose of this paper is to demonstrate that process verification has matured to a level where it can be used in practice. This paper reports on new verification techniques that can be used to assess the correctness of real‐life models.

The proposed approach relies on using formal methods to determine the correctness of business processes with cancellation and OR‐joins. The paper also demonstrates how reduction rules can be used to improve the efficiency. These techniques are presented in the context of the workflow language yet another workflow language (YAWL) that provides direct support for 20 most frequently used patterns found today (including cancellation and OR‐joins). But the results also apply to other languages with these features (e.g. BPMN, EPCs, UML activity diagrams, etc.). An editor has been developed that provides diagnostic information based on the techniques presented in this paper.

The paper proposes four properties for business processes with cancellation and OR‐joins, namely: soundness, weak soundness, irreducible cancellation regions and immutable OR‐joins and develop new techniques to verify these properties. Reduction rules have been used as a means of improving the efficiency of the algorithm. The paper demonstrates the feasibility of this verification approach using a realistic and complex business process, the visa application process for general skilled migration to Australia, modelled as a YAWL workflow with cancellation regions and OR‐joins.

Business processes sometimes require complex execution interdependencies to properly complete a process. For instance, it is possible that certain activities need to be cancelled mid‐way though the process. Some parallel activities may require complex “wait and see” style synchronisation depending on a given context. These types of business processes can be found in various domains, such as application integration, B2B commerce, web service composition and workflow systems. Even though cancellation and sophisticated join structures are present in many business processes, existing verification techniques are unable to deal with such processes. Hence, this paper plays an important role in making process verification a reality.

The Cyprus conflict is a classical case of protracted ethnic conflict with very obvious and important international dimensions. It is one of the major unresolved inter national conflicts, which for decades attracts the attention of the international community. The involvement of many countries and international organizations in the Cyprus conflict demonstrates the importance and seriousness of the conflict. During the last decades the conflict has cost a lot both for the Greek Cypriots and for the Turkish Cypriots. It claimed a lot of lives and caused serious economic damages and psychological destruction. The conflict began in the 1950s, erupted violently with blood shed at the end of 1963,and culminated in 1974 with the interventions of Greece and Turkey that led to the island’s current de facto division as the Greek Cypriot South and Turkish Cypriot North. Over the past 40 years many states have came out with various initiatives and have proposed various approaches for final settlement of the conflict. It also has been addressed by dozens of UN Security Council resolutions but all these have proved to be futile so far.

This paper presents a theoretical framework that extends the benefits of some core elements of operations strategy to the field of entrepreneurship. We show that the field of operations strategy, with its predominant focus on fit among configuration, competencies, and logistics, offers valuable insights into many strategic and tactical challenges that entrepreneurs face as they try to create business models and enter new markets or establish footholds in existing, but well‐defended markets. It is our aim to highlight the need for future endeavors linking the two fields.

From the perspective of housing affordability, Portugal is an interesting case study, considering that Portugal ranks 5th in terms of price-to-income ratio and has experienced, since 2015, a significant increase in real estate prices.

The provision of housing is a critical social development factor. With the growing worldwide urbanization and the demand pressure over real estate in many cities, the problem of affordability has gained increase attention by policy makers. Housing affordability is hardly a new topic from a literature perspective, but the recent post-pandemic worldwide inflation growth has re-centered affordability as key topic in the housing agenda. This paper provides a comprehensive overview on past literature and a detailed analysis on the Portuguese market at the municipal level, by analyzing the changes in housing affordability in recent years.

Despite this growth, overall, affordability has improved. The study also shows the importance of municipal-level analysis, given the significant geographical differences. The authors' study confirms that many municipalities, outside metropolitan areas, exhibit low levels of affordability. Nevertheless, markets with higher average real estate values tend to exhibit even lower affordability, outpacing the higher levels of income.

Previous studies have focused on affordability issues on a national or highly aggregated level or focusing only on the two largest metropolitan areas in the country. This paper provides a deeper understanding on the inequalities of housing affordability between Portuguese municipalities.

This article examines the future of e‐money as a payment instrument and some of the microeconomic policy issues it will raise. The paper is in two parts. This first part focuses on the various forms which electronic money is likely to take in the future, and considers key technological and economic factors that will shape its evolution. Part 2, to be published in the next issue of foresight, examines some of the major regulatory and institutional issues that are likely to have a bearing on the adoption of e‐money, notably concerns related to the regulation of payment systems, security, privacy and consumer protection.
