Purpose – Agile methods often refer to software development methodology and practices used in software industry but the elements and principles of agile methods have been used also for operational development in various organizations. In general, the agile development process means an incremental work process that promotes the importance of customer satisfaction, collaboration, communication, teamwork, good quality and planned follow-up practices. The paper aims to discuss these issues. Design/methodology/approach – This paper first presents an overview of agile methods after which it addresses the most relevant ones for developing, evaluating and managing the academic library. The paper discusses the utilization of these methods in the context of an academic library presenting the case of Tampere University of Technology Library. Findings – After a short practical experience of implementing agility into development processes, the following elements of agility can be considered the most effective and relevant: appreciating the needs of the customers, eliminating the waste, quality assurance, ability to redesign and make decisions fast and empowering the team. Practical implications – The library of Tampere Univeristy of Technology made an early adoption of the methods in its development projects during 2012. The paper refers to concrete initiatives that have already been taken to improve development processes as well as discuss the challenges when applying agile methods in order to change quite traditional working culture. Originality/value – The paper discusses what the library can achieve by adapting a fresh approach for developing, evaluating and managing its operations and how the library staff can benefit from the agile way of working.

Purpose The idea that user comments on journalistic articles would help to increase the quality of the media has long been greeted with enthusiasm. By now, however, these high hopes have mostly evaporated. Practical experience has shown that user participation does not automatically lead to better journalism but may also result in hate speech and systematic trolling – thus having a dysfunctional impact on journalistic actors. Although empirical journalism research has made it possible to describe various kinds of disruptive follow-up communication on journalistic platforms, it has not yet succeeded in explaining what exactly drives certain users to indulge in flaming and trolling. This paper intends to fill this gap. Design/methodology/approach It does so on the basis of problem-centered interviews with media users who regularly publish negative comments on news websites. Findings The evaluation allows for a nuanced view on current phenomena of dysfunctional follow-up communication on journalistic news sites. It shows that the typical “troll” does not exist. Instead, it seems to be more appropriate to differentiate disruptive commenters according to their varying backgrounds and motives. Quite often, the interviewed users display a distinct political (or other) devotion to a certain cause that rather makes them appear as “warriors of faith.” However, they are united in their dissatisfaction with the quality of the (mass) media, which they attack critically and often with a harsh tone. Originality/value The study reflects these differences by developing a typology of dysfunctional online commenters. By helping to understand their aims and intentions, it contributes to the development of sustainable strategies for stimulating constructive user participation in a post-truth age.

Low Performance

The Project proposes a solution to the academic problems that arise in the student departments and in the accountability of the directors of the school, for failing to achieve the recommended indicators of the percentage of school leavers or the decrease in the percentages of school degree that are presented by the low performance in students with levels of conditionality (Regular student, Irregular student and Deserter); through a computer solution that provides the academic follow-up of students of Computer Systems Engineering (ISC) of the Tecnológico Nacional de México (TecNM) campus Oaxaca and support in addressing the problem. This prototype integrade some processes that are carried out manually, resulting in cost and time savings, added to the fact that the student will also have quick and detailed access to their academic situation and suggestions in other areas such as tutorial support (scholarships, counseling, psychological support) if required. The solution proposed "Early Warning System (SAT) for students of the ISC of the TecNM Campus Oaxaca through a web apps is based theoretically on research on standard processes to low performance identification, the classification according to the academic status that the accreditation guidelines of subjects issued by the National Technological of Mexico and the academic follow-up of students. The methodology used for the analysis and design of the system was applied research, the collection of information through questionnaires and interviews. At the end of the research, a web app for the academic follow-up of students was obtained to support the School Services Department, Division of Professional Studies and Academic Development as the Institutional Coordinator of the Tutoring Program; in which SCRUM was used as an agile development methodology for software development. It is considered according to the initial evidence that the work carried out contributes to the line of research on educational technology management, since the proposal optimizes the management of resources and time.

Object. The effects of gamma thalamotomy for parkinsonian and other kinds of tremor were evaluated. Methods. Thirty-six thalamotomies were performed in 31 patients by using a 4-mm collimator. The maximum dose was 150 Gy in the initial six cases, which was reduced to 130 Gy thereafter. The longest follow-up period was 6 years. The target was determined on T2-weighted and proton magnetic resonance (MR) images. The point chosen was in the lateral-most part of the thalamic ventralis intermedius nucleus. This is in keeping with open thalamotomy as practiced at the authors' institution. In 15 cases, gamma thalamotomy was the first surgical procedure. In other cases, previous therapeutic or vascular lesions were visible to facilitate targeting. Two types of tissue reaction were onserved on MR imaging: a simple oval shape and a complex irregular shape. Neither of these changes affected the clinical course. In the majority of cases, the tremor subsided after a latent interval of approximately 1 year after irradiation. The earliest response was demonstrated at 3 months. In five cases the tremor remained. In four of these cases, a second radiation session was administered. One of these four patients as well as another patient with an unsatisfactory result underwent open thalamotomy with microrecording. In both cases, depth recording adjacent to the necrotic area revealed normal neuronal activity, including the rhythmic discharge of tremor. Minor coagulation was performed and resulted in immediate and complete arrest of the remaining tremor. Conclusions. Gamma thalamotomy for Parkinson's disease seems to be an alternative useful method in selected cases.

Object. A consecutive series of 240 patients with arteriovenous malformations (AVMs) treated by gamma knife radiosurgery (GKS) between March 1993 and March 1999 was evaluated to assess the efficacy and safety of radiosurgery for cerebral AVMs larger than 10 cm3 in volume. Methods. Seventy-six patients (32%) had AVM nidus volumes of more than 10 cm3. During radiosurgery, targeting and delineation of AVM nidi were based on integrated stereotactic magnetic resonance (MR) imaging and x-ray angiography. The radiation treatment was performed using multiple small isocenters to improve conformity of the treatment volume. The mean dose inside the nidus was kept between 20 Gy and 24 Gy. The margin dose ranged between 15 to 18 Gy placed at the 55 to 60% isodose centers. Follow up ranged from 12 to 73 months. There was complete obliteration in 24 patients with an AVM volume of more than 10 cm3 and in 91 patients with an AVM volume of less than 10 cm3. The latency for complete obliteration in larger-volume AVMs was significantly longer. In Kaplan—Meier analysis, the complete obliteration rate in 40 months was 77% in AVMs with volumes between 10 to 15 cm3, as compared with 25% for AVMs with a volume of more than 15 cm3. In the latter, the obliteration rate had increased to 58% at 50 months. The follow-up MR images revealed that large-volume AVMs had higher incidences of postradiosurgical edema, petechiae, and hemorrhage. The bleeding rate before cure was 9.2% (seven of 76) for AVMs with a volume exceeding 10 cm3, and 1.8% (three of 164) for AVMs with a volume less than 10 cm3. Although focal edema was more frequently found in large AVMs, most of the cases were reversible. Permanent neurological complications were found in 3.9% (three of 76) of the patients with an AVM volume of more than 10 cm3, 3.8% (three of 80) of those with AVM volume of 3 to 10 cm3, and 2.4% (two of 84) of those with an AVM volume less than 3 cm3. These differences in complications rate were not significant. Conclusions. Recent improvement of radiosurgery in conjunction with stereotactic MR targeting and multiplanar dose planning has permitted the treatment of larger AVMs. It is suggested that gamma knife radiosurgery is effective for treating AVMs as large as 30 cm3 in volume with an acceptable risk.

Object. The authors sought to evaluate the effects of gamma knife radiosurgery (GKS) on cerebral arteriovenous malformations (AVMs) and the factors associated with complete occlusion. Methods. A total of 301 radiosurgical procedures for 277 cerebral AVMs were performed between December 1988 and December 1999. Two hundred seventy-eight lesions in 254 patients who were treated with GKS from May 1992 to December 1999 were analyzed. Several clinical and radiological parameters were evaluated. Conclusions. The total obliteration rate for the cases with an adequate radiological follow up of more than 2 years was 78.9%. In multivariate analysis, maximum diameter, angiographically delineated shape of the AVM nidus, and the number of draining veins significantly influenced the result of radiosurgery. In addition, margin radiation dose, Spetzler—Martin grade, and the flow pattern of the AVM nidus also had some influence on the outcome. In addition to the size, topography, and radiosurgical parameters of AVMs, it would seem to be necessary to consider the angioarchitectural and hemodynamic aspects to select proper candidates for radiosurgery.

Object. The authors conducted a study to determine the optimal radiation dose for vestibular schwannoma (VS) and to examine the histopathology in cases of treatment failure for better understanding of the effects of irradiation. Methods. A retrospective study was performed of 195 patients with VS; there were 113 female and 82 male patients whose mean age was 51 years (range 11–82 years). Seventy-two patients (37%) had undergone partial or total excision of their tumor prior to gamma knife surgery (GKS). The mean tumor volume was 4.1 cm3 (range 0.04–23.1 cm3). Multiisocenter dose planning placed a prescription dose of 11 to 18.2 Gy on the 50 to 94% isodose located at the tumor margin. Clinical and magnetic resonance (MR) imaging follow-up evaluations were performed every 6 months. A loss of central enhancement was demonstrated on MR imaging in 69.5% of the patients. At the latest MR imaging assessment decreased or stable tumor volume was demonstrated in 93.6% of the patients. During a median follow-up period of 31 months resection was avoided in 96.8% of cases. Uncontrolled tumor swelling was noted in five patients at 3.5, 17, 24, 33, and 62 months after GKS, respectively. Twelve of 20 patients retained serviceable hearing. Two patients experienced a temporary facial palsy. Two patients developed a new trigeminal neuralgia. There was no treatment-related death. Histopathological examination of specimens in three cases (one at 62 months after GKS) revealed a long-lasting radiation effect on vessels inside the tumor. Conclusions. Radiosurgery had a long-term radiation effect on VSs for up to 5 years. A margin 12-Gy dose with homogeneous distribution is effective in preventing tumor progression, while posing no serious threat to normal cranial nerve function.

Object. The authors sought to assess the safety and efficacy of stereotactic radiotherapy when using a linear accelerator equipped with a micromultileaf collimator for the treatment of patients with acoustic neuromas. Methods. Fifty patients harboring acoustic neuromas were treated with stereotactic radiotherapy between September 1997 and June 2003. Two patients were lost to follow-up review. Patient age ranged from 20 to 76 years (median 59 years), and none had neurofibromatosis. Forty-two patients had useful hearing prior to stereotactic radiotherapy. The fifth and seventh cranial nerve functions were normal in 44 and 46 patients, respectively. Tumor volume ranged from 0.3 to 19.25 ml (median 2.51 ml). The largest tumor dimension varied from 0.6 to 4 cm (median 2.2 cm). Treatment planning in all patients included computerized tomography and magnetic resonance image fusion and beam shaping by using a micromultileaf collimator. The planning target volume included the contrast-enhancing tumor mass and a margin of normal tissue varying from 1 to 3 mm (median 2 mm). All tumors were treated with 6-MV photons and received 54 Gy prescribed at the 90% isodose line encompassing the planning target volume. A sustained increase greater than 2 mm in any tumor dimension was defined as local relapse. The follow-up duration varied from 6 to 74 months (median 36 months). The local tumor control rate in the 48 patients available for follow up was 100%. Central tumor hypodensity occurred in 32 patients (67%) at a median of 6 months following stereotactic radiotherapy. In 12 patients (25%), tumor size increased 1 to 2 mm at a median of 6 months following stereotactic radiotherapy. Increased tumor size in six of these patients was transient. In 13 patients (27%), tumor size decreased 1 to 14 mm at a median of 6 months after treatment. Useful hearing was preserved in 39 patients (93%). New facial numbness occurred in one patient (2.2%) with normal fifth cranial nerve function prior to stereotactic radiotherapy. New facial palsy occurred in one patient (2.1%) with normal seventh cranial nerve function prior to treatment. No patient's pretreatment dysfunction of the fifth or seventh cranial nerve worsened after stereotactic radiotherapy. Tinnitus improved in six patients and worsened in two. Conclusions. Stereotactic radiotherapy using field shaping for the treatment of acoustic neuromas achieves high rates of tumor control and preservation of useful hearing. The technique produces low rates of damage to the fifth and seventh cranial nerves. Long-term follow-up studies are necessary to confirm these findings.
