The wheel of collaboration tools
2006
Paper from the 2006 20th anniversary conference on Computer supported cooperative work We present a holistic framework for analyzing and specifying collaboration solutions, developed by an oil and gas company in response to practical needs in supporting integrated collaboration and information management. A typology of collaboration tool capabilities, termed the Wheel of Collaboration Tools (WCT), is described. We assess its contributions, and discuss areas of application and potential further development. Our intent is to stimulate discussion and research related to this type of collaboration modeling.
Cooperatives' performance relative to investor-owned firms: a non-distorted approach for the wine sector
2021
PurposeThis study aims to investigate whether significant performance differences between cooperatives and investor-owned firms (IOFs) may exist.Design/methodology/approachBased on data from a sample of Italian wine firms for the period from 2009 to 2018, an adjusted measure of performance called earnings before interests, taxes, depreciations and amortizations gross the raw materials cost was adopted to consider the different objectives of cooperatives relative to those of IOFs.FindingsEmpirical evidence shows that in the context under analysis, cooperatives have performed better than IOFs.Originality/valueDespite the theoretical literature suggesting that the cooperative form of organizat…
Forward Kinematic Modelling with Radial Basis Function Neural Network Tuned with a Novel Meta-Heuristic Algorithm for Robotic Manipulators
2022
The complexity of forward kinematic modelling increases with the increase in the degrees of freedom for a manipulator. To reduce the computational weight and time lag for desired output transformation, this paper proposes a forward kinematic model mapped with the help of the Radial Basis Function Neural Network (RBFNN) architecture tuned by a novel meta-heuristic algorithm, namely, the Cooperative Search Optimisation Algorithm (CSOA). The architecture presented is able to automatically learn the kinematic properties of the manipulator. Learning is accomplished iteratively based only on the observation of the input–output relationship. Related simulations are carried out on a 3-Degrees…
Mesh complications following prolapse surgery: management and outcome.
2011
Abstract Objective This is a description of complications following prolapse surgery with the use of alloplastic materials, the management and outcome. Study design 54 women have been referred to Mainz, urogynecology referral center due to complications following mesh-augmented prolapse surgery. Results The complaints who lead to the admission are expressed by the new terminology and standardized classification for complications arising directly from the insertion of prostheses and grafts in female pelvic floor surgery [1] . Pain (66.7%), mesh erosion (55.6%) and vaginal discharge (48.1%) were the most frequent complaints. Revision was performed after a median time of 27.2 months post mesh …
Cooperation in Rural Areas as a Local System Development Opportunity
2017
The development of rural areas requires the adoption of technology innovation and market approach strategies without departing from the specific features of local production systems, such as agricultural practices and the wealth of knowledge of operators. It is even better the exploitation of these resources to characterize the competitive positioning of territorial systems. In this framework, the cooperative Rinascita, which works in an internal rural area of Sicily region (Southern Italy), represents an attempt to maintain agricultural activities, traditions and rural culture as well as to promote and contribute to the development of the area by giving value to and promoting, a typical lo…
POOLED ESTIMATES OF INCIDENCE OF ENDOPHTHALMITIS AFTER INTRAVITREAL INJECTION OF ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR AGENTS WITH AND WITHOUT TOPI…
2017
Purpose: To assess the effect of topical antibiotic prophylaxis on postoperative endophthalmitis after intravitreal injection of anti-vascular endothelial growth factor agents.Methods: A systematic literature search was performed from inception to March 2016 using PubMed, Medline, Web of Science, Embase, and the Cochrane Library, to identify articles that reported cases of endophthalmitis after intravitreal injection of anti-vascular endothelial growth factor agents. We used a pooled analysis to estimate the incidence of cases of endophthalmitis who developed after injections performed with and without topical antibiotic prophylaxis. We used regression analysis to explore the effects of stu…
Superior mesenteric vein thrombosis following open right hemicolectomy and cholecystectomy. Case report
2020
INTRODUZIONE: La SMVT è una seria, rara complicanza della chirurgia addominale. I fattori di rischio sono molteplici, ma scarsamente descritti tanto che i dati sono insufficienti per creare gold standard per la diagnosi e trattamento. La SMVT ha un ampio spettro di presentazioni cliniche, così che spesso la sua diagnosi precoce può essere complessa. CASE REPORT: Una donna obesa di 56 anni con un disordine protrombotico ereditario è stata sottoposta ad emicolectomia destra e colecistectomia open; l’immediato decorso post-operatorio è stato regolare e la paziente è stata dimessa in quinta giornata post-operatoria. In ottava giornata post-operatoria la paziente ha presentato dolore addominale …
Negatively cooperative binding of melittin to neutral phospholipid vesicles
2007
Abstract The association of basic amphipathic peptides to neutral phospholipid membranes is investigated in terms of binding and partition models. The binding of native and modified melittin to egg-yolk phosphatidylcholine vesicles is studied by steady-state fluorescence spectroscopy. The effect of the ionic strength shows an enhancement of the association as the ionic strength increases. After correction for electrostatic effects by the Gouy–Chapman theory, the melittin binding isotherms could be described by a partition model. In terms of conventional binding mechanisms, which do not take into account electrostatic effects, this would correspond to a negative cooperativity. A plausible wa…
Effects of preemptive analgesia with intravenous acetaminophen on postoperative pain relief in patients undergoing third molar surgery: a prospective…
2020
Background The efficacy of preemptive analgesia in managing postoperative pain remains controversial. The aim of this study was to compare the efficacy of intravenous (IV) acetaminophen administered before or immediately after the surgical extraction of an impacted mandibular third molar. Material and Methods This prospective randomized clinical trial included 120 patients. The patients were assigned to one of three groups: the preoperative-treatment group (pre-group), which received 1000 mg of IV acetaminophen 20 min before surgery; the postoperative-treatment group (post-group), which received 1000 mg of IV acetaminophen after surgery; the no-treatment group (control-group), which did not…
Quadratus Lumborum Block Reduces Postoperative Opioid Consumption and Decreases Persistent Postoperative Pain Severity in Patients Undergoing Both Op…
2021
Background: New regional techniques can improve pain management after nephrectomy. Methods: This study was a randomized controlled trial conducted at two teaching hospitals. Patients undergoing elective open and laparoscopic nephrectomy were eligible to participate in the trial. A total of 100 patients were divided into a quadratus lumborum block (QLB) group (50 patients) and a control (CON) group (50 patients). At the end of surgery, but while still under general anesthesia, unilateral QLB with ropivacaine was performed on the side of nephrectomy for patients in the QLB group. The main measured outcome of this study was oxycodone consumption via a patient-controlled anesthesia (PCA) pump d…
