The Open Innovation in Science research field: a collaborative conceptualisation approach
2020
Openness and collaboration in scientific research are attracting increasing attention from scholars and practitioners alike. However, a common understanding of these phenomena is hindered by disciplinary boundaries and disconnected research streams. We link dispersed knowledge on Open Innovation, Open Science, and related concepts such as Responsible Research and Innovation by proposing a unifying Open Innovation in Science (OIS) Research Framework. This framework captures the antecedents, contingencies, and consequences of open and collaborative practices along the entire process of generating and disseminating scientific insights and translating them into innovation. Moreover, it elucidat…
Deformable object segmentation in ultra-sound images
2013
Breast cancer is the second most common type of cancer being the leading cause of cancer death among females both in western and in economically developing countries. Medical imaging is key for early detection, diagnosis and treatment follow-up. Despite Digital Mammography (DM) remains the reference imaging modality, Ultra-Sound (US) imaging has proven to be a successful adjunct image modality for breast cancer screening, specially as a consequence of the discriminative capabilities that US offers for differentiating between solid lesions that are benign or malignant. Despite US usability,US suffers inconveniences due to its natural noise that compromises the diagnosis capabilities of radio…
Synthesis of rigid ethynyl-bridged polytopic picolinate ligands for MOF applications
2015
Abstract Segmented homopolytopic ligands that consist of a rigid central arylene platform, ethynylene spacers, and terminal chelating picolinate subunits have been synthesized in good yields in a two-step procedure involving a Sonogashira-type cross coupling reaction between the ester methyl 5-bromopyridine-2-carboxylate and several arylacetylenes, followed by hydrolysis of the resulting methyl picolinates. A similar strategy has been employed for the preparation of heteroditopic ligands containing picolinate and a second non-chelating pyridine or benzoate unit. The compounds are potential candidates for organic linkers in metal–organic frameworks (MOFs).
Metal-Organic Frameworks as Unique Platforms to Gain Insight of σ-Hole Interactions for the Removal of Organic Dyes from Aquatic Ecosystems.
2022
The combination of high crystallinity and rich host-guest chemistry in metal-organic frameworks (MOFs), have situated them in an advantageous position, with respect to traditional porous materials, to gain insight on specific weak noncovalent supramolecular interactions. In particular, sulfur σ-hole interactions are known to play a key role in the biological activity of living beings as well as on relevant molecular recognitions processes. However, so far, they have been barely explored. Here, we describe both how the combination of the intrinsic features of MOFs, especially the possibility of using single-crystal X-ray crystallography (SCXRD), can be an extremely valuable tool to gain insi…
Incorporation of metal-organic framework amino-modified MIL-101 into glycidyl methacrylate monoliths for nano LC separation.
2018
Metal-organic frameworks consisting of amino-modified MIL-101(M: Cr, Al, and Fe) crystals have been synthesized and subsequently incorporated to glycidyl methacrylate monoliths to develop novel stationary phases for nano-liquid chromatography. Two incorporation approaches of these materials in monoliths were explored. The metal-organic framework materials were firstly attached to the pore surface through reaction of epoxy groups present in the parent glycidyl methacrylate-based monolith. Alternatively, NH2 -MIL-101(M) were admixed in the polymerization mixture. Using short time UV-initiated polymerization, monolithic beds with homogenously dispersed metal-organic frameworks were obtained. T…
Water oxidation catalyzed by molecular di- and nonanuclear Fe complexes: importance of a proper ligand framework.
2016
The synthesis of two molecular iron complexes, a dinuclear iron(III,III) complex and a nonanuclear iron complex, based on the di-nucleating ligand 2,2-(2-hydroxy-5-methyl-1,3-phenylene)bis(1H-benzo[d]imidazole-4-carboxylic acid) is described. The two iron complexes were found to drive the oxidation of water by the one-electron oxidant [Ru(bpy)(3)](3+).

The effect of organizational culture on deviant behaviors in the workplace
2017
This study investigated the impact of organizational culture (OC) on deviant behaviors in the workplace (workplace deviant behaviors: WDB). We tested the hypothesis that different types of OC (according to the Competing Values Framework model) had an impact on WDB, in addition to the effect of Big Five personality traits. Survey research was undertaken with 954 employees of 30 enterprises in the public and private field, using a hierarchical model approach (HLM) to test the effects of four types of OC (Clan; Adhocracy; Market, Hierarchy) on WDB, over and above the effect of Five Personality traits. The HLM results partially supported our hypotheses, showing that the OC had a significant eff…
The “Dean’s Squeeze” revisited: a contextual approach
2016
Purpose– The purpose of this paper is to develop a conceptual framework for identifying the primary tensions that business school dean’s encounter when moving between different university contexts.Design/methodology/approach– The paper is part of a larger research project on the development of business schools. This conceptual paper builds on the studies and personal experiences of business schools and their management in a number of different countries, primarily in Europe, North America, Asia, and the Middle East.Findings– The present study argues that as a response to the increasing corporatization of higher education, the university sector has fragmented into at least three identifiable…
Categorizing and assessing multi-campus universities in contemporary higher education
2016
Multi-campus universities are not a new phenomenon per se, but they have become an increasing feature of contemporary higher education systems all over the world. In the case of Northern Europe, multi-campus universities are the consequence of contraction patterns resulting from overcapacity, fragmentation and rising competition. This paper has two main objectives. First, to take stock of the existing scientific literature on multi-campus universities and, on that basis, develop a novel conceptual framework for categorizing such systems, with focus on the level of autonomy and profile enjoyed by the individual campuses composing a given system or university. Second, we provide new empirical…
Democratic Dialogue and Development: An Intellectual Obituary of Björn Gustavsen
2018
Abstract Bjorn Gustavsen, with an original professional background as a lawyer and judge in his native Norway, had a formative role in organisational development processes in Norway, Sweden, Scandinavia and the European Union over four decades. Following in the tradition of Norwegian working life research by Trist and Thorsrud, he provided the conceptual framework and practical case studies which have driven major national and international programmes. He learned from different experience of organisational change in, for example, the USA and Japan, but he identified a distinctive way forward for the European Union, where he acted as a senior adviser. In contrast to conventional Taylorist to…
