Objectives: The description of minor hallucinatory phenomena (presence, passage hallucinations) has widened the spectrum of psychosis in Parkinson's disease (PD). Minor hallucinatory phenomena seem to antedate the development of more severe hallucinations. Early detection of minor hallucinations may be useful for screening patients with more severe endophenotypes. Motivated by the observation of "de novo," drug-naive PD patients reporting minor hallucinations, we aimed to prospectively identify "de novo" untreated PD patients experiencing hallucinatory phenomena, and to compare their clinico-demographic characteristics with those of untreated PD patients without hallucinations and healthy controls. Methods: Screening and description of psychosis was assessed by the Movement Disorders Society Unified Parkinson's Disease Rating Scale-Part I and a structured interview covering all types of psychotic phenomena reported in PD. Clinical, neuropsychological, and demographic data of PD patients with and without psychotic phenomena were compared with those of age- and education-matched healthy controls. Results: Fifty drug-naive, "de novo" PD patients and 100 controls were prospectively included. Minor hallucinations were experienced in 42% (21 of 50) PD patients and 5% controls (P<0.0001). Coexistence of passage and presence hallucinations was the most common finding. Unexpectedly, 33.3% of patients with minor hallucinations manifested these as a pre-motor symptom, starting 7 months to 8 years before first parkinsonian motor symptoms. The presence of minor hallucinations was significantly associated with presence of rapid eye movement sleep behavior disorder. Conclusions: In this first study to prospectively analyze the frequency of minor hallucinatory phenomena in incident, untreated PD patients, hallucinations appeared as a frequent early non-motor symptom that may even predate the onset of parkinsonism. © 2016 International Parkinson and Movement Disorder Society.

Previous studies show empirical evidence on the positive effect on students' performance from the adoption of innovations in the technology of teaching and learning. These innovations do not affect all teaching methods and learning styles equally. Rather, it depends on some variables, such as the strategy of a university towards adoption of Information and Communication Technologies (ICT), students' abilities, technology uses in the educational process by teachers and students, or the selection of a methodology that matches with digital uses. This paper provides answers to these questions with data from an experimental set-up performed within the eLene-EE project, and using an empirical model based on structural equations. Our results show that motivation is the main variable affecting performance of online students, confirming the importance of this factor as a source of educational efficiency. Motivation appears in our model as a latent variable receiving the influence of students' perception of efficiency, which is, in turn, a driver for the indirect positive and significant effect on students' performance from students' ability in ICT uses. © 2013 Elsevier Ltd.

The digital divide was initially defined by socioeconomic variables, mainly the level of family income, but now it focuses on how the Internet is used and is called digital inequality. In the case of universities, recent studies have pointed to the existence of patterns that are dependent on a variety of socioeconomic variables. This article analyses the effect that the level of family income, gender and age of students from five Ecuadorian universities has on Internet use for academic activities and entertainment purposes. In the procedure applied to a sample of 4,697 students, factor analysis was used to reduce the data, and multivariate logistic regression was used to estimate the relationships. The results show that the higher the level of family income, the better the technology use for academic activities. Regarding entertainment, the level of income does not determine the intensity of technology use, though it does determine the types of tool that students use. With reference to gender, men have a greater tendency to use technology for entertainment, but there is no difference between genders when it comes to academic uses. © 2015, Italian e-Learning Association.

The increased proliferation and accessibility of geographic data are changing the landscape of services based on geographic information. From the analysis of recent job offers posted in American university libraries, we discuss what could be the role of the information professional in this new context, with respect to the management and dissemination of geographic data collections, looking for synergies for mutual benefit between academic libraries and their information professionals and the geographic data community that uses geographic information systems (GIS). In fact, this activity would be one more among the data curation or data sets preservation tasks needed currently in many disciplines.

Background/aims: The Parkinson's Disease - Cognitive Functional Rating Scale (PD-CFRS) was designed to avoid motor biases in capturing the functional impact of cognitive impairment in Parkinson's disease (PD). Its performance capturing functional impairment in other conditions leading to cognitive dysfunction is unknown. We compare it with non-specific Instrumental Activities of Daily Living scales. Methods: Two hundred consecutive patients diagnosed in a community hospital with mild cognitive impairment (MCI) [31 MCI-amnestic; 33 MCI-multi-domain; 33 PD-MCI] and dementia [35 Alzheimer's disease; 34 vascular dementia; 34 PD with dementia] were assessed on the PD-CFRS, the Blessed Dementia Scale (BDS), the Clinical Dementia Rating - Sumof Boxes (CDR-SOB), and given a comprehensive cognitive assessment. Diagnostic accuracy and optimal cut-off scores were calculated for the PD-CFRS and compared with each functional measure. Results: The PD-CFRS presented high concurrent validity and significant correlation with both BDS and CDR-SOB, and cognitive scores offering a similar discrimination accuracy to non-specific scales [PD-CFRS ≥ 9 (sensitivity= 0.94; specificity = 0.95)]. No changes appear in cut-off scores when excluding PD patients. Effect size analysis indicated no relevant interference with PD-CFRS scores between the principal cognitive subgroups. Discussion: The findings extend the clinimetric properties of the PD-CFRS and indicate it as an adequate instrument to capture the full spectrum of functional consequences of cognitive decline in the community. © 2015 Elsevier B.V.

The task of the healthcare professionals is a combination of science and art, knowledge and technical resources coupled with emotional intelligence. Aim: To know, through acting training techniques that enhance the development of emotional intelligence, the opinion of the professionals working in healthcare centers and their reflections on their experience. Methods: From 2008 to 2013, a multidisciplinary team conducted fifteen editions of a training course on how to recognize and manage one's emotions. The experience was assessed using mixed methods: qualitative (reflexive essays) and quantitative methods (satisfaction questionnaire, 1-to-10 scale). Results: A total of 231 professionals participated: 26% were nurses, 6% physicians, and 68% auxiliary nurses. The reflexive essays of the participants reflected their satisfaction and their perception of having re-discovered resources and natural abilities to promote communication and professional and personal growth. The average rating for satisfaction was 9.75 points. Conclusions: The training was perceived as effective. The participants were enthusiastic towards the experience that combined a environment to express their emotions appropriately together with guided acting training techniques. © 2016 Fundación Index.

The consumption of ostrich meat was introduced into Europe in a relatively short time. Considered even today as an exotic meat, its inclusion in the usual sources of animal protein in our context has been repeatedly assessed, because it converge some of the most interesting nutritional characteristics of poultry and red meat. Over ten years later, the consumption of ostrich meat continues crossing a road that lies increasingly away from the exotic to become very slow, in usual. Although information on their nutritional value is still limited, we have more data showing protein values quite similar to other meats but with a smaller proportion of histidine and serine; fat values close to poultry meat low in fat; cholesterol values, vary according to the court, but similar to beef or chicken, and an improved lipid profile compared to the meat of turkey meat, lamb or beef. The information on its vitamins and minerals throws elevated iron and vitamin B12, higher amounts of vitamin E and Zn than other types of meat and a low concentration of sodium.


The aim of this investigation is to estimate the economic and social impacts of cruise tourism on Barcelona. For this purpose, we examine the development and evolution of cruise tourism in the city in recent decades, as well as public and private collaboration in recent years to promote and invest in improving the urban city and cruise port infrastructure. Although the spectacular growth of cruise tourism has positioned Barcelona as a world leader in this sector, it has impacted on the destination both positively and negatively. Residents’ perceptions regarding this type of tourism are also discussed as they are key to the strategic management planning and sustainable development of cruise tourism in Barcelona. © 2015, Universitat Autonoma de Barcelona.

As the literature (Juanola; Calbó Valles, 2006; Fontal, 2003; Calaf, 2009) suggests and from what we saw in our research, heritage education promotes students' personal developm ent. During the academic year 2008/09, we carried out a pilot experiment in heritage education through internet within the framework of Catalonia. It brought different actors (cultural managers, teachers, secondary school students and coordinators) into a virtual platform as user and co-producers of digital objects with heritage contents. The study evidences the importance of heritage institutions delivering contents on the world wide web. This contribution wants to show educational uses of digital objects with heritage contents (images, videos, etc.) so that students of compulsory secondary educational acquire knowledge and skills related to heritage, syllabus core subjects and digital literacy. © 2013 IEEE.
