Abstract

Purpose

The purpose of this paper is to propose a model for sharing network capacity on demand among different underloaded and overloaded P2P ROME‐enabled networks. The paper aims to target networks of nodes with highly dynamic workload fluctuations that may experience a burst of traffic and/or massive nodes' failure rates.

Design/methodology/approach

The paper shows that when locally available network capacity is not adequate for the workload requirements, the excessive capacity needs to be sought into other networks with more availability. A random flat P2P overlay of the ROME servers is used for the discovery and movement of nodes between two networks. Centralised or decentralised DHT‐based directories of available nodes cannot cope with high workload fluctuations and frequent join/leave actions of nodes. The paper also introduces semantics to refine the answers to the ones with the most appropriate nodes for the requesting network and to find the requested capacity faster and more efficiently. The behaviour of the model is simulated to evaluate with several experiments the model based on some metrics.

Findings

The paper finds that all the user queries of an overloaded underlying network are dropped if G‐ROME is not used but as G‐ROME overlay satisfies the requested capacity of a ROME server, its Chord ring size increases. In case of uniformly distributed and/or plentiful capacity over the overlay, shallow searches may give very good results. On the contrary, deeper searches are required for scarce capacity but the number of messages increases almost exponentially.

Originality/value

This paper provides a model for moving the required resources to the requesting job environment rather than the job and its context to the resource.

Abstract

In the last 10 years or so, a growing body of research has highlighted the importance of social movements as the mechanism through which fields change or new fields emerge. This article contributes to this body of research by studying how an organization was able to promote institutional change from the center of a field by channeling the legitimacy generated by local religious movements. Data comes from the archives of a special commission within the Catholic Church that developed rules for adjudicating miracles performed by candidates to sainthood. The social movement is composed of candidates and their supporters who mobilized local communities using miracles. The period of the analysis was the aftermath of the Protestant Schism, when long-established practices and beliefs were fundamentally challenged. By approving miracles that created ties between individuals that spanned across kinship and social status boundaries, the commission was able to channel legitimacy into the wounded core of the Church. At the same time, receiving Rome’s approval reduced the competition the candidate’s supporters faced from other religious activists. The noncontentious interaction that occurred between the two actors gave birth to the field of modern sainthood. The main implication for organization theory is that, even in the absence of conflict, a new environment and ideology can emerge endogenously from the center of a field and transform both the organization and the social movement.

Abstract

Purpose

The purpose of this paper is to: describe and contextualize the aims and distinctive and common characteristics of cannabis festivals in countries with different cannabis policies; assess characteristics of participants; identify reasons to attend cannabis festivals; explore to which extent cannabis festivals contribute to the social and cultural acceptance of cannabis, as perceived by attendees.

Design/methodology/approach

The approach incorporates three methods of data collection in the research design; quantitative research among 1,355 participants, participant observation and interviews with the organizers.

Findings

Cannabis festivals in Amsterdam, Berlin, Rome and Athens have common features but also maintain and reproduce local, social and cultural characteristics. Cannabis festivals, as well as their attendees, represent heterogeneous categories. The style of the festival – music festival or march combined with music – affects the main reason for attendance by the participants. In cannabis festivals more similar to music festivals the majority of the respondents attended for entertainment while at the cannabis festivals in the form of a march combined with music the majority attended for protest. Furthermore, increasing age, residency and the high frequency of cannabis use are factors that led the participants to attend for protest.

Originality/value

The research on cannabis festivals is limited. This paper not only explores the aims of cannabis festivals in four capital cities of Europe and the characteristics of their attendees including motivations, but also offers interesting insights for understanding the ways in which political and social constructions like cannabis festivals shape attitudes, perception and behaviors around cannabis use.

Abstract

Avant d'examiner les aspects essentiels du mouvement touristique à Rome, ainsi que de l'ensemble des activités et des organisations qui s'y rattachent, nous devons considérer rapidement la nature particulière des attraits touristiques de la ville. En effet, chaque centre touristique a sa physionomie particulière, en fonction de laquelle devront être étudiés les aspects et les éléments permettant de formuler de nouveaux programmes et de nouvelles initiatives en vue d'une plus vaste mise en valeur de son potentiel. Il y a des localités à caractère essentiellement climatique, des localités panoramiques, des localités artistiques, historiques ou thermales et ainsi de suite. Leur importance s'accroît tout naturellement, lorsque deux ou plusieurs de ces caractéristiques s'additionnent.

Abstract

The Roman Empire illustrates how change occurs in complex social systems. An analysis of: the effects of transformational leadership and transactional leadership styles in complex social systems; and the relationship between leadership style and the social context is conducted. Julius Caesar is shown to have failed to create a new method of governing Rome. Augustus Caesar, however, created the basis for the Roman Empire. Their careers show that change which is incremental and does not violate the core culture of a system is more likely to transform a social system than more radical, transformational methods.

Abstract

Purpose

Within the service sectors, Knowledge Intensive Business Services (KIBS) play an important role in local and regional economies as sources of competitive advantages and providing knowledge-intensive inputs to the business process of small and medium-sized enterprises. This study aims to analyze the changes in financial performance of KIBS industry in Italy over the period from 2012 to 2017.

Design/methodology/approach

This paper examines the efficiency of the KIBS firms by applying data envelopment analysis (DEA) to compute the Malmquist Productivity Index for the period under investigation. The DEA-based Malmquist productivity analysis is applied at firm level using a sample consisting 1.674 companies, representative of the Italian KIBS sector and related to three different NACE activity code (72-computing services; 73-research and development; 74 other professional business activities). The efficiency measures are then used to characterize KIBS firm financial performance through the analysis of average productivity patterns grouped by Italian geographical regions. The Malmquist productivity measures are decomposed into two components: efficiency change and technical change index. The overall analysis is coupled with a financial ratio analysis approach, selecting return on equity (ROE) and leverage ratio as descriptor to validate the results and better characterize differences in efficiency patterns among geographic-based groups of KIBS companies.

Findings

Over the period 2015-2017, the results show that the average annual growth of the overall Malmquist productivity index was positive in nine Italian regions that represent only 17 per cent of the total KIBS firms selected. On the other side, a decrease of the average performance measure is observed for the five geographic areas that contribute to 75.7 per cent of the total sample. In general, the technological change component, as a measure of innovation, strongly limits the productivity growth behavior of KIBS industry for all geographic regions. The use of selected financial ratio does not provide additional insight to the performance investigation and further in-depth studies are needed to better evaluate the correlation between average productivity results and regional business dynamics.

Practical implications

The study investigates the applicability of DEA-based Malmquist indices to the analysis of the productivity behavior of KIBS industry at regional level. It will be of value to provide first evidence to the policymakers to understand industry growth pattern in time frame selected and relate them to additional business factors to detect specific industry constraints.

Originality/value

The analysis in this paper contributes to the existing body of knowledge on industry performance measurement by applying specific analytical techniques to the productivity of Italian KIBS companies. The paper also contributes to the limited body of academic literature investigating KIBS industry at national level proposing a methodological framework that constitutes a first attempt to track average productivity behavior at regional level.

Abstract

This paper takes the stance that there are two criteria for evaluation of diversity in organizations. These criteria are (a) competition with other organizations and (b) the maintenance of the organization across time. Organizations which seek diversity without considering its effects on competitive and maintenance goals place themselves at a disadvantage vis‐a‐vis their competitors. Two case examples, the Persian and Roman Empires, are used to show how different diversity management practices affect organizations. Differences between the two empires are related to the degree to which they allowed for inclusion of diverse cultural groups. The Persian Empire was exclusionary. The Roman Empire was inclusionary. Roman inclusionary practices were based on merit. Inclusion by merit is shown to lead to increased organizational effectiveness primarily in terms of increased organizational resiliency across time.

Abstract

Dominant in the urban sociology literature on immigrant incorporation is the role of ethnic enclaves – ethnic neighborhoods that provide a “port of entry” or “context of reception” and help facilitate incorporation in the host society by generating informal resources, networks, and institutions that provide linguistic and cultural services and products (Portes & Rumbaut, 1990). While New York City's stature as a global city is replete with nostalgia about historic ethnic immigrant neighborhoods, contemporary immigrant settlement is once again transforming urban landscapes not only by renewing enclave formations but by creating numerous multiethnic, multiracial neighborhoods (Hum, 2004). As often cited, in no other historic period has New York City received as diverse a range of people from all over the world – certainly, this diversity is reshaping local neighborhood landscapes.
