Dazing Diversity: Investigating the Determinants and Consequences of Decision Paralysis
2012
This article makes new contributions to the assessment of negative effects on consumer choice behavior due to high product variety by (1) developing a holistic framework to identify the determinants and, for the first time, consequences of decision paralysis; (2) introducing a novel construct, namely, tendencies toward paralysis, that refers to the extent of decision makers’ preference (a) to maintain the status quo, (b) to omit, and/or (c) to delay choice, as well as providing an appropriate measurement model incorporating these three dimensions of decision paralysis that previously have been analyzed only separately; and (3) analyzing potential moderating effects of decision makers’ predi…
CLINICAL OUTCOMES OF SELF-EXPAMDABLE METALLIC STENTS IN PALLIATION OF MALIGNANT ANASTOMOTIC STRICTURES: A SINGLE CENTER EXPERIENCE
2015
Background: self-expandable metallic stents (SEMS) are employed as the preferred non surgical palliative treatment for gastric outlet obstruction due to malignancies. Metallic stents are often employed to treat malignant anastomotic obstructions after surgicsl interventions as esophagojejunostomy, gastrojejunostomy and esophagogastrojejunostomy. Methods: this case series reports prospectively the clinical outcomes of SEMS in the palliative care of malignant anastomotic strictures caused by the recurrence gastric cancer follwing gastric surgery as oncological curative treatment, in a series of nine consecutive patients, treated between January 2009 and december 2012 in our center. Results: N…
Antecedents and consequences of market orientation in public organisations
2001
The aim of this article is to link research on market orientation in the field of marketing with the proposals of reform and modernisation made in the administrative and political field. Market orientation in business organisations is a highly topical issue, or even more, it is considered by someacademicians as the new marketing paradigm. Following these studies and their proposals of application in other sectors, a market orientation model is developed, from a public management perspective, in the setting of local governments through testing a set ofhypotheses about the construct and its antecedents and consequences. Antecedents explaining why some local governments are more market oriente…
Brand love in progress – the interdependence of brand love antecedents in consideration of relationship duration
2015
Purpose – This paper aims to investigate the dynamic nature of consumer–brand relationships and, in particular, the passionate dimension of brand love. It explores the relevance of the two dimensions of the identification construct (inner and social self) for the creation of passionate love for a brand. More precisely, it attends to the possible mediating character of identification between the perceived utilitarian or hedonic value and passionate brand love. These effects are analysed in consideration of the moderating effect of relationship duration taking a further-reaching perspective and contributing to the understanding of the transformation of the brand love construct within a long-…
A family life cycle model adapted to the Spanish environment
2001
Aims to demonstrate, from a marketing and market segmentation point of view, the need to adapt the construct of the family life cycle to the particular features of the Spanish social environment, given the obvious differences in the structure of Spanish households in relation to the USA. From this marketing and cross‐cultural approach, a review of the literature has been conducted on the evolution of the construct and the most significant models that have been arising as the outcome of that evolution. A new life cycle model has been designed reflecting these particular features. Also, on the basis of data taken from the Family Budgets Survey, the capacity of the adapted model has been analy…
Empathic Relationships in Professional Services and the Moderating Role of Relationship Age
2016
Empathy has been identified as a key success factor for employees who interact with customers. Despite its overall relevance, only a few studies have acknowledged its multidimensional nature. Knowledge remains scarce about the relative impact of cognitive and affective empathy on relational outcomes. In addition, few pieces of research have explicitly acknowledged empathy as theorized within stage-models focusing on the communication of empathy. The authors conceptualize empathy as a multidimensional construct perceived by the client. Empathy has to be communicated to be effective, while customers’ perceptions of empathy may also be more complex as they distinguish between cognitive and aff…
Enforcing mobile security with location-aware role-based access control
2013
This paper describes how location-aware role-based access control RBAC can be implemented on top of the Geospatial eXtensible Access Control Markup Language GeoXACML. It furthermore sketches how spatial separation of duty constraints both static and dynamic can be implemented using GeoXACML on top of the XACML RBAC profile. The solution uses physical addressing of geographical locations, which facilitates easy deployment of authorisation profiles to the mobile device. Location-aware RBAC can be used to implement location-dependent access control and also other security enhancing solutions on mobile devices, such as location-dependent device locking, firewall, intrusion prevention or payment…
Macroelement Model for In-Plane and Out-of-Plane Responses of Masonry Infills in Frame Structures
2018
A new macroelement model is presented in this paper for the simulation of the in-plane (IP) and out-of-plane (OOP) response of infilled frames subjected to seismic actions. The model consists of two diagonal, one horizontal, and one vertical struts. Each strut is represented by two fiber-section beam-column elements. The model is able to capture the arching action of the wall under an OOP load as well as the interaction between the IP and OOP actions. The proposed modeling approach is sufficiently simple and efficient that it can be used for the static or dynamic analysis of an entire structural system. An experimental validation has been carried out. A further numerical study performed wit…
Definition of diagonal Poisson's ratio and elastic modulus for infill masonry walls
2014
The prediction of the response of infilled frames through the simplified approach of substituting the infill with an equivalent pin-jointed strut is treated. In this framework the results of an experimental study for the mechanical characterization of different types of masonry infills having the aim of estimating strength, Young modulus and Poisson's ratio are presented. Four types of masonry were investigated and subjected to ordinary compressive tests orthogonally to the mortar beds and along the directions of the mortar beds. The experimental campaign confirmed the possibility of using an orthotropic plate model for prediction of the Poisson's ratio and Young modulus along the diagonal …
Infilled frames: developments in the evaluation of the stiffening effect of infills
2003
In order to consider the modified seismic response of framed structures in the presence of masonry infills, proper models have to be formulated. Because of the complexity of the problem, a careful definition of a diagonal pin-jointed strut, able to represent the horizontal force-interstorey displacement cyclic law of the actual infill, may be a solution. In this connection the present paper shows a generalized criterion for the determination of the ideal cross-section of the strut mentioned before. The procedure is based on the equivalence between the lateral stiffness of the actual infilled frame scheme during the conventional elastic stage of the response and the lateral stiffness of the …
