Abstract
Traditionally, studies on the influence and impact of knowledge-producing organisations have been addressed by means of strict economic analysis, stressing their economic impact to a local, regional or national extent. In the present study an alternative methodology is put forward in order to evaluate the international scientific impact and influence of a knowledge-producing and -diffusing institution. We introduce a new methodology, based on scientometric and bibliometric tools which complement traditional assessments by considering the influence of a R&D institution when looking at the scientific production undertaken and the recognition of its releVance by its international peer community. Focusing on the most prolific scientific areas of the R&D institution (INESC Porto), and resorting to published scientific work recorded in the Science Citation Index (SCI) we show that the R&D institution has enlarged its international scientific network. The logit estimations demonstrate that the wide geographical influence of INESC Porto scientific research is a result not of its international positioning in terms of coauthorships, but rather a result of the quality of its scientific output. © EuroJournals Publishing, Inc. 2011.

Abstract
The motivation to perform this particular research comes from a need which we feel exists for further research in this area. It is necessary to answer a set of questions both empirical (observed over the years in the area of health and safety) and theoretical (following an analysis of the international literature) relative to the dimension of the problem of musculoskeletal injuries resulting from the exercise of the nursing profession in a hospital context. Research questions addressed include: 1) Are there complaints associated to the performing of nursing tasks? 2) How serious in terms of absolute numbers are musculoskeletal injuries? 3) What sort of influence does the environment (namely buildings) play, as well as technology / equipment, and work organization? Furthermore, 4) What should be present in the workplace but is not? After analyzing survey (of 168 active nurses in Portuguese hospitals) and interview data and having observed nurses at work, accompanying them in their day-to-day tasks, there is a global tendency to consider that, over the last twelve months of work, in a hospital context, nursing professionals have felt pain or musculoskeletal discomfort in a part of their bodies. Research results point also to more training and more adequate working spaces being needed in order to decrease musculoskeletal injuries amongst nurses. Furthermore, the more widespread usage of technological means which are lacking in some hospitals (such as beds with adjustable height, trapeze-type supporting bars attached above beds, patient transferring lifts and transferring belts) or in bad condition (such as wheels on beds, wheelchairs, and stretchers, which makes moving patients difficult) could also reveal itself to be an important aid, presenting itself as a solution to the problem discussed herein, on the one hand due to the number of injuries on the other due to the need for more professionals.

Abstract
Network effects occur when the benefit that agents derive from a good or service depends on how many other agents adopt the same good or service. This strategic complementarity between consumers' actions has several implications on tie behavior of firms: For instance, firms need to gain advantage from early marketing stages. Network effects are intrinsically a dynamic phenomenon: past consumption of the good influences the utility of present consumers. This effect can be either direct, when consumers value interaction with their peers, and/or indirect, through an increase in the quality of the good. This chapter surveys the literature on dynamic network effects. First we provide general formulations for the modelization of network effects in a dynamic setting. Second, we analyse recent developments in the literature on firms' strategies in the context of dynamic network effects. We survey the literature both on monopoly and oligopoly markets. In the case of oligopoly markets, we distinguish between situations in which firms produce horizontally and vertically differentiated goods. Main results on pricing and evolution of market shares are exposed.

Abstract
This conceptual paper is developed in the realm of strategic change communication. The purpose of this paper is to present our Business Narrative Modelling Language (BNML) (Oliveira and Ferreira, 2010a) as a tool for facilitating change. We illustrate how BNML has been used in real life cases to discuss strategy. Following data collection using a qualitative methodology and an analysis of the "As-Is" situation we proceed to construct a representation of the future desired ("To-Be") situation, in both situations using BNML. We start by defining the organizational actors relevant to value creation, we then map out their interactions in the organizational context, and study how relevant deliverables are exchanged, both tangible and intangible, along various storylines, one per actor. The social interaction leading to value creation happens according to a pattern sequence (using patterns taken from Bjork and Holopainen, 2005, which are intuitively comprehensible) and is instantiated according to an Enterprise Ontology (Uschold et al., 1998) (Oliveira and Ferreira, 2010a, b). By combining various sensemaking strategies such as the narrative, visual mapping and quantification our BNML scores high on accuracy, simplicity and generality (Langley, 1999) thus providing an attractive alternative to other techniques available to researchers and consultants and used to "connect and organize dispersed organizational knowledge" (Huff and Jenkins, 2002, p. 14).
