The purpose of this paper concerns the dimensions of relevance in information retrieval systems and their completeness in new retrieval contexts such as mobile search. Geography as a factor in relevance is little understood and information seeking is assumed to take place in indoor environments. Yet the rise of information seeking on the move using mobile devices implies the need to better understand the kind of situational relevance operating in this kind of context.

The paper outlines and explores a geographic information seeking process in which geographic information needs (conditioned by needs and tasks, in context) drive the acquisition and use of geographic information objects, which in turn influence geographic behaviour in the environment. Geographic relevance is defined as “a relation between a geographic information need” (like an attention span) and “the spatio‐temporal expression of the geographic information objects needed to satisfy it” (like an area of influence). Some empirical examples are given to indicate the theoretical and practical application of this work.

The paper sets out definitions of geographical information needs based on cognitive and geographic criteria, and proposes four canonical cases, which might be theorised as anomalous states of geographic knowledge (ASGK). The paper argues that geographic relevance is best defined as a spatio‐temporally extended relation between information need (an “attention” span) and geographic information object (a zone of “influence”), and it defines four domains of geographic relevance. Finally a model of geographic relevance is suggested in which attention and influence are modelled as map layers whose intersection can define the nature of the relation.

Geographic relevance is a new field of research that has so far been poorly defined and little researched. This paper sets out new principles for the study of geographic information behaviour.

The purpose of this paper is to discuss the emerging geographic features of current concepts of relevance, and to improve, modify, and extend the framework proposed by Mizzaro (1998). The objective is to define a new framework able to account, more completely and precisely, for the notions of relevance involved in mobile information seeking scenarios.

The authors formalise two new dimensions of relevance. The first dimension emphasises the spatio-temporal nature of the information seeking process. The second dimension allows us to describe how different concepts of relevance rely on different abstractions of reality.

The new framework allows: to conceptualise the point in space and time at which a given notion of relevance refers to; to conceptualise the level of abstraction taken into account by a given notion of relevance; and to include widely adopted facets (e.g. users mobility, preferences, and social context) in the classification of notions of relevance.

The conceptual discussion presented in this paper contributes to the future development of relevance in the scope of mobile information seeking scenarios. The authors provide a more comprehensive framework for conceptualization, development, and classification of notions of relevance in the field of information retrieval and location-based services.

The purpose of this paper is to investigate the most recurrent variables characterizing the collaborative relationships of industrial symbiosis (IS) (hereinafter also referred to as “anatomic” variables) established in the attempt to adopt circular economy (CE) by collecting evidence from a rich empirical set of implementation cases in Italy.

The current literature on IS was reviewed, and a content analysis was performed to identify and define the “anatomic” variables affecting its adoption in the circular economy. We followed a multiple-case study methodology investigating 50 cases of IS in Italy and performed a content analysis of the “anatomic” variables characterizing each case.

This research proposes the “anatomic” variables (i.e. industrial sectors involved, public actors involvement, governmental support, facilitator involvement and geographical proximity) explaining the cases of IS in the circular economy. Each “anatomic” variable is discussed at length based on the empirical evidence collected, with a particular reference to the impact on the different development strategies (i.e. “bottom-up” and “top-down”) in the cases observed.

Current literature on IS focuses on a sub-set of variables characterizing collaboration in IS. This research builds on extant literature to define a new framework of five purposeful “anatomic” variables defining IS in the circular economy. Moreover, we also collect and discuss a broad variety of empirical evidence in what is a still under-investigated context (i.e. Italy).

With this chapter, we seek to shed light on the question how headquarters (HQ) can cope with geographic distance and effectively transfer relevant knowledge to their subsidiaries. By constructing a mediating model, we aim at disentangling the effects of geographic distance on the relevance of HQ knowledge to their subsidiaries, via the creation of a shared context between HQ and their subsidiaries. We tested our hypotheses using partial least squares based structural equation modelling on a sample of 124 European subsidiaries. We did not find a significant direct relationship between geographic distance and HQ knowledge relevance. Yet, we found support for our mediation hypotheses that geographic distance makes it more difficult for HQ to establish a shared normative and operational context, but that both dimensions of shared context can help HQ to transfer relevant knowledge to their subsidiaries. We contribute to the research on knowledge flows in multinational corporations (MNC) by investigating knowledge relevance directly rather than knowledge flows as such. We also advance our understanding of shared context in HQ-subsidiary relationships by showing that shared context comprises an operational and a normative dimension. Moreover, we contribute to social learning theory in basing our reasoning on the idea that shared practices and social relationships help overcoming distance to manage knowledge transfer more effectively. Finally, we add to the research of distance in international business by conceptualizing space, organizational context and knowledge transfer in one comprehensive model.

There is an open discussion in the geographic information community about the use of digital libraries or search engines for the discovery of resources. Some researchers suggest that search engines are a feasible alternative for searching geographic web services based on anecdotal evidence. The purpose of this study is to measure the performance of Bing (formerly Microsoft Live Search), Google and Yahoo! in searching standardised XML documents that describe, identify and locate geographic web services.

The study performed an automated evaluation of three search engines using their application programming interfaces. The queries asked for XML documents describing geographic web services, and documents containing links to those documents. Relevant XML documents linked from the documents found in the search results were also included in the evaluation.

The study reveals that the discovery of geographic web services in search engines does not require the use of advanced search operators. Data collected suggest that a resource‐oriented search should combine simple queries to search engines with the exploration of the pages linked from the search results. Finally the study identifies Yahoo! as the best performer.

This is the first study that measures and compares the performance of major search engines in the discovery of geographic web services. Previous studies were focused on demonstrating the technical feasibility of the approach. The paper also reveals that some technical advances in search engines could harm resource‐oriented queries.

The purpose of this paper is to investigate the value relevance of segment information for both public and private sector banks in India. In doing so, this paper examines a rapidly developing economy and perhaps its most critical sector during this period of strong economic growth.

In this study uses the simplified Ohlson model, for a sample of 136 private sector and public sector banks for the period 2007-2010 in India.

The paper finds that public sector banks have higher share prices, higher earnings and more equity compared with private sector banks. Segment earnings data is highly value relevant for both sectors; however, segment equity data is only marginally value relevant for Indian banks. The number of segments is also value relevant and associated with higher share prices.

The results of this study contribute additional evidence to the literature on segment reporting by studying the effect of adoption of segment reporting in an emerging market. Findings from the paper are particularly relevant as India is currently in the process of changing its segment reporting requirements and moving to an IFRS-based segment standard.

The purpose of the paper is to compare the role of the sector and geographical features in explaining the performance of a hotel structure.

The paper constructs a measure of net profit for available room (GOPPAR) for a representative sample of Italian hotels and uses a constrained linear regression model in order to identify the role of sectoral and geographical features. The analysis is released adopting a multiple cross sectional approach and considering not only the average role of sectoral and geographic characteristic, but also the time trend of relation inspected.

Results obtained show that the overall national trend is not significant for explaining the performance of each hotel. Considering geographical and sectoral features, the first of these explain better the disalignment of the performance respect to the national average.

The paper proposes an analysis of the hotel industry using a standard geo‐sectoral classification. More data about the characteristics of the firms considered in the sample could allow to define a more detailed model that consider also other hotel features that could impact on the demand and supply of the service.

Results could be useful for the hotel chains and for institutional investors specialized in the hotel sector, in order to define a first guideline for the property selection process and diversification portfolio strategy.

The paper represents the first work that analyse the role of regional and sectoral factors in explaining the performance of the hotel industry and supports the thesis proposed with and empirical evidence on world leading market (Italy).

The purpose of this paper is to assess the changes in segment reporting practices of German listed firms under the new segment reporting standard IFRS 8.

The authors compare hand-collected segment disclosures of German firms in the first IFRS 8 year with those reported in the last IAS 14R year.

The authors do not find substantial changes in the segment disclosures of German firms under IFRS 8. While the number of reportable segments slightly increased, the amount of information disclosed for each reportable segment decreased. The same applies to geographic areas reported as secondary segments under IAS 14R compared to entity-wide disclosures under IFRS 8. Furthermore, even though more country-specific information was provided, many firms still disclosed only broad geographic areas.

Future research should extend the analysis to consider more than one year of data following IFRS 8’s adoption and to examine the impact of the standard on smaller firms. Moreover, investigating economic benefits for investors and other financial statement users following IFRS 8’s adoption could be an avenue for future research.

The findings indicate that the International Accounting Standards Board’s (IASB) expectations regarding changes in segment reporting practices under IFRS 8 have only partially been met. The results also reveal some cases of segment reporting practice where compliance is at least questionable. Both findings are of interest to standard-setters and regulators.

The paper provides new insights into the effects of IFRS 8’s adoption in Germany and thus contributes to the post-implementation review of IFRS 8 carried out by the IASB in 2012/2013. The study sheds light on the consequences of applying the “management approach” to segment reporting, thereby contributing to the theoretical discussion on the adequacy of the different concepts for disclosing segment information.

The purpose of this paper is to shed light on transitions from the state of unemployment to that of employment and of inactivity in Italy and Spain.

First, the paper investigates the determinants of unemployment outflows in these two Mediterranean labour markets. Then, the paper examines discrepancies and similarities between specific outflow determinants, especially the interactions between gender and marital status, by comparing results obtained across countries.

The findings of the paper suggest that gender and marital status influence the probability of unemployment outflows in both countries, although not in the same way, especially with reference to marital status. Discrepancies also emerge in relation to the role of geographical area of residence.

International comparisons of unemployment outflows are rather new in the literature, and as far as we know none have been performed using European Union Statistics on Income and Living Conditions data. Further, although studies quite often examine the issue of gender-related labour mobility using the European Community Household Panel survey that took place in the 1990s (Arulampalam et al., 2007; Garcia Pérez and Rebollo Sanz, 2005; Theodossiou and Zangelidis, 2009), one of the main contributions of this paper is that it provides a systematic examination of the issue, considering the influence of gender and marital status differences on patterns of unemployment outflows to employment and inactivity.

This study investigates how investors perceive the impact of U.S.‐based MNCs geographic and business segment diversification upon their earnings performance. Pooled cross‐sectional annual earnings response regressions for the years 1993 through 1997 are used for this investigation. Our results show that geographic segment diversification is valued by investors more than the business segment diversification especially in two cases: 1) when the business segmentation is low; and 2) when geographic segmentation is high. These results imply that business segment diversification is only valued when it takes place in international markets where it is relatively more difficult for individual investors to replicate industry diversified portfolio for themselves. Our research illuminates the contextual aspects of investors' perceptions of geographic and business segment diversification for multinational corporations by explicitly controlling for one dimension of corporate diversification while examining the earning‐returns impact of the other type of corporate diversification.
