Collaborating to achieve corporate social responsibility and sustainability? Possibilities and problems

Purpose: The purpose of this paper is to investigate the possibilities and problems for collaboration in the area of corporate social responsibility (CSR) and sustainability. The paper explores the nature and concept of collaboration and its forms, and critically evaluates the potential contribution a collaborative approach between agencies might offer to these agendas. Design/methodology/approach: The paper explores different forms of research on collaboration, together with a UK Government report on collaboration, to evaluate how the issue is addressed in theory and practice. Findings: Sustainable development creates extensive challenges for a wide range of agencies, including governments, non-governmental organizations, businesses and civil society. It is unlikely, however, that solutions will be found in any one quarter. Collaboration between agencies in some form would seem a logical step in supporting measures towards a more responsible and environmentally sustainable global economy. Originality/value: The paper offers new insights into developing a research and praxis agenda for collaborative possibilities towards the advancement of CSR and sustainability. © Emerald Group Publishing Limited.

La fictohistoria o historiografía imaginaria en las literaturas románicas desde el siglo XIX: ensayo de tipología y panorama de un género formal insospechado (II)

El doble aspecto documental y artístico de la escritura de la historia ha quedado prácticamente oculto por la insistencia en el carácter científico de la disciplina y su expulsión subsiguiente del canon literario desde el siglo XIX. El cultivo de la historiografía ficticia o imaginaria (fictohistoria) surgió entonces como un modo de salvar la literariedad de la historia, en su calidad de género formal, mediante el uso del discurso historiográfico como procedimiento retórico para conseguir un efecto de historicidad en textos que son, no obstante, claramente ficticios, y que tienen a menudo un carácter satírico o admonitorio. Esto no está reñido con el hecho de que la mayoría manifieste en primer lugar una reflexión sobre el devenir de la humanidad, es decir, sobre la Historia. Los ejemplos de este género son relativamente abundantes y se pueden clasificar en varias categorías temáticas. Esta segunda parte del estudio se centra en la historia prospectiva.

Acute Cholecystitis as a Complication After Colonoscopy: A Case Report and Literature Review

Acute cholecystitis after colonoscopy is a rare event, with less than 10 cases described in the literature. We report the case of a male patient with silent gallstones who underwent colonoscopy for follow-up of his Crohn’s disease. The colonoscopy revealed erosions in the terminal ileum, from which biopsies were taken. A sessile polyp 4 mm in diameter at the recto-sigmoid junction was also removed. Less than 24 h after the colonoscopy, the patient complained of upper right quadrant pain, nausea and vomiting. Based on the clinical findings, laboratory data and ultrasonography, we diagnosed acute cholecystitis and excluded any complication after the colonoscopy. Laparoscopic cholecystectomy was performed and the patient was discharged.

Interrelated product design activities sequencing with efficient tabu search algorithms

This paper proposes and investigates a metaheuristic tabu search algorithm (TSA) that generates optimal or near optimal solutions sequences for the feedback length minimization problem (FLMP) associated to a design structure matrix (DSM). The FLMP is a non-linear combinatorial optimization problem, belonging to the NP-hard class, and therefore finding an exact optimal solution is very hard and time consuming, especially on medium and large problem instances. First, we introduce the subject and provide a review of the related literature and problem definitions. Using the tabu search method (TSM) paradigm, this paper presents a new tabu search algorithm that generates optimal or sub-optimal solutions for the feedback length minimization problem, using two different neighborhoods based on swaps of two activities and shifting an activity to a different position. Furthermore, this paper includes numerical results for analyzing the performance of the proposed TSA and for fixing the proper values of its parameters. Then we compare our results on benchmarked problems with those already published in the literature. We conclude that the proposed tabu search algorithm is very promising because it outperforms the existing methods, and because no other tabu search method for the FLMP is reported in the literature. The proposed tabu search algorithm applied to the process layer of the multidimensional design structure matrices proves to be a key optimization method for an optimal product development.
