A manic episode after bilateral subthalamic stimulation in a patient with advanced Parkinson's disease

Deep brain stimulation (DBS) has proven to be an effective treatment for patients with refractory symptoms in the advanced stages of Parkinson's disease. However, different psychiatric and cognitive problems may occur after DBS. We report a case of a manic episode after DBS of the subthalamic nucleus in a patient with advanced Parkinson's disease. After slow and gradually restart of the neurostimulation using the lowest effective intensity, the motor symptoms remained sufficiently under control without causing any psychiatric problems

Nanostructured polymer coatings for controlling the wettability of fibrous surfaces

In this research we present a new approach for modifying and functionalizing the surface properties of fibrous substrates, especially cellulose-based products, by the deposition of organic nanoparticle coatings. The partial imidisation of high-molecular weight poly(styrene-maleic anhydride) in presence of ammonium hydroxide results in a stable water-borne dispersion of nanoparticles with sizes of 50 to 100 nm. The hydrophobic properties of coated paper surfaces are governed by a unique combination of chemical (degree of imidisation) and topographic (porosity and roughness) effects: it has been found that the contact angle increases at a higher degree of imidisation and higher surface roughness. As such, maximum advancing contact angles in the range of 140 to 150° and receding contact angles of 50° can be obtained on paper surfaces

TDABC is a relatively new costing management technique, initially developed for manufacturing processes, which is gaining attention in libraries. This is because TDABC is a fast and simple method that only requires two parameters, an estimation of time required to perform an activity and the unit cost per time of supplying capacity. A few case studies have been documented with regard to TDABC in libraries; all of them being oriented to analyse specific library activities such as inter-library loan, acquisition and circulation processes. The primary focus of this paper is to describe TDABC implementation in one of the most important library processes, namely cataloguing. In particular, original and copy cataloguing are analysed through a case study to demonstrate the applicability and usefulness of TDABC to perform cost analysis of cataloguing processes.volumen 23; número

Improving Library Management by Using Cost Analysis Tools: A Case Study for Cataloguing Processes

Libraries have been constantly subject to continuous changes especially due to evolving user needs and emerging technologies. In addition, the rising cost of information and ever-shrinking budgets constantly challenge the managerial skills of librarians. As a consequence, library managers are required to increase understanding of library activities and their related costs on the one hand to justify budget increases, staff requirements and creation of new services; and on the other hand, to negotiate work arrangements, or face budget reductions. Accurate cost estimations and efficient process management therefore constitute valuable data for facilitating an understanding of topics such as the relationship between services and costs, the prioritization of expenditure and reduction of costs, and the identification of different costing drivers involved in library activities. Time-Driven Activity-Based Costing (TDABC) is a relatively new costing management technique, initially developed for manufacturing processes, which is gaining attention in academic libraries. This is because TDABC is a fast and simple method that only requires two parameters: an estimation of the time required to perform each activity and the unit cost per time of supplying capacity. A few case studies have been documented on TDABC in libraries; all of them oriented towards analyzing specific library activities such as inter-library loan, acquisition and circulation processes. More research is still required to determine the usefulness and effectiveness of applying TDABC to other library services. The primary focus of this paper is on describing the application of TDABC in cataloging processes. We first explain the steps involved in implementing TDABC in two types of cataloging activities: original and copy cataloging. We then show the benefits and disadvantages of conducting a TDABC analysis. Next we discuss the similarities and differences found in original and copy cataloging with respect to time and cost per activity. We end the paper by providing recommendations for operational improvements where appropriate. Through a case study in the Arenberg Campus Library of KU Leuven, the paper demonstrates that TDABC is a useful method for performing a cost analysis of cataloging processes in academic libraries and consequently for providing valuable data for managerial decisions.status: publishe
