there is currently limited information about the effects of dementia diseases on semantic memory for music: memory for musical objects and concepts. Here we review available evidence and emerging research directions in semantic memory for music in the degenerative dementias. Neurodegenerative pathologies affect distributed brain networks and can therefore provide a perspective on musical semantic memory that complements the traditional neuropsychological paradigm of the focal brain lesion. Recent work suggests that semantic memory for music may be fractionated and may share certain cognitive organizational principles with semantic memory for other kinds of material. Profiles of impairment on different dimensions of musical semantic memory may show some specificity for particular dementia diseases (for example, semantic dementia versus Alzheimer's disease).

Conventional olfactometric techniques have been used to evaluate odours from sewage treatment and sludge storage facilities primarily in terms of odour concentration relative to their detection thresholds. However, such data conveys limited information that would be useful for determining the causes of most odours or the most appropriate remediation measures to be taken. Thispaper discusses some recent work undertaken to characterise the olfactometric profiles of different odours. Standard descriptive terms were used to characterise odours at normalised, moderately strong concentrations. These were used directly for the calculation of hedonic tone. They were also collated into a small number of generic odour groups and plotted to allow visual comparisons of different odour profile fingerprints. Such odour characterisations have proved to be very useful and may easily be incorporated into normal olfactometric evaluations.

Through this chapter, the authors aim at describing Gamification—the use of game elements in non-ludic environments—to identify its limits and lacks as well as its assets. Indeed, it has been developed to answer a need that arouses out of the Human Computer Interaction (HCI) field evolutions, and it could be valuable in that scope. The authors propose a definition of Gamification according to several different dimensions that are part of the HCI design field. They suggest it as a first step towards a guiding design framework aimed at designers. They mention future research directions that would help in going further and enriching the framework, leading to the creation of a design model for user experience design through Gamification. The authors finally raise some ethical concerns about the meaning of Gamification itself.

Abstract The term semantic dementia was devised by Snowden et al. in 1989 and nowadays, the semantic dementia syndrome is recognized as one of the clinical forms of frontotemporal lobar degeneration (FTLD) and is characterized by a language semantic disturbance associated to non-verbal semantic memory impairment. Objectives: The aim of this study was to describe a Brazilian sample of 19 semantic dementia cases, emphasizing the clinical characteristics important for differential diagnosis of this syndrome. Methods: Nineteen cases with semantic dementia were evaluated between 1999 and 2007. All patients were submitted to neurological evaluation, neuroimaging exams and cognitive, language and semantic memory evaluation. Results: All patients presented fluent spontaneous speech, preservation of syntactic and phonological aspects of the language, word-finding difficulty, semantic paraphasias, word comprehension impairment, low performance in visual confrontation naming tasks, impairment on tests of non-verbal semantic memory and preservation of autobiographical memory and visuospatial skills. Regarding radiological investigations, temporal lobe atrophy and/or hypoperfusion were found in all patients. Conclusions: The cognitive, linguistic and of neuroimaging data in our case series corroborate other studies showing that semantic dementia constitutes a syndrome with well defined clinical characteristics associated to temporal lobe atrophy.

The Way

This paper does not address the issue of aid effectiveness—that is, the extent to which foreign aid dollars actually achieve their goals—but on “best practices” in the way in which official aid is given, an important component of the wider debate. First we discuss best practice for an ideal aid agency and the difficulties that aid agencies face because they are typically not accountable to their intended beneficiaries. Next we consider the transparency of aid agencies and four additional dimensions of aid practice: specialization, or the degree to which aid is not framgemented among too many donors, too many countries, and too many sectors for each donor); selectivity, or the extent to which aid avoids corrupt autocrats and goes to the poorest countries; use of ineffective aid channels such as tied aid, food aid, and technical assistance; and the overhead costs of aid agencies. We compare 48 aid agencies along these dimensions, distinguishing between bilateral and multilateral ones. Using the admittedly limited information we have, we rank the aid agencies on different dimensions of aid practice and then provide one final comprehensive ranking. We present these results as an illustrative exercise to move the aid discussion forward.

Storage Disorders

Objective. Previous studies have shown that some patients with semantic dementia (SD) have memory storage disorders, while others have access disorders. Here, we report three SD cases with both disorders.Methods. Ten pictures and ten words were prepared as visual stimuli to determine if the patients could correctly answer names and select pictures after hearing the names of items (Card Presentation Task, assessing memory storage disorder). In a second task, the viewing time was set at 20 or 300 msec (Momentary Presentation Task, evaluating memory access disorder) using items for which correct answers were given in the first task. The results were compared with those for 6 patients with Alzheimer’s disease (AD).Results. The SD patients had lower scores than the AD group for both tasks, suggesting both storage and access disorders. The AD group had almost perfect scores on the Card Presentation Task but showed impairment on the Momentary Presentation Task, although to a lesser extent than the SD cases.Conclusions. These results suggest that SD patients have both storage and access disorders and have more severe access disorder than patients with AD.

Metal Incorporation

Recent work has indicated that iron (oxyhydr-)oxides are capable of structurally incorporating and releasing metals and nutrients as a result of Fe2+-induced iron oxide recrystallization. In the present paper, we briefly review the current literature examining the mechanisms by which iron oxides recrystallize and summarize how recrystallization affects metal incorporation and release. We also provide new experimental evidence for the Fe2+-induced release of structural manganese from manganese-doped goethite. Currently, the exact mechanism(s) for Fe2+-induced recrystallization remain elusive, although they are likely to be both oxide-and metal-dependent. We conclude by discussing some future research directions for Fe2+-catalysed iron oxide recrystallization.
