Facilitating independence: The benefits of a post-diagnostic support project for people with dementia.
No full textProviding support in the form of information, advice and access to services or social events is promoted as beneficial for people newly diagnosed with dementia and their families. This paper reports on key findings from an evaluation of a post-diagnostic support pilot project in Scotland addressing local service gaps, namely information provision, emotional and practical support and maintaining community links. Twenty-seven participants (14 people newly diagnosed with dementia and 13 family carers) were interviewed at two time points: T1 shortly after joining the pilot project and T2 approximately six months later, to ascertain their views on existing services and the support offered by the pilot project. A comparative thematic analysis revealed that the project facilitated increased independence (associated with increased motivation and self-confidence) of people with dementia. The project illustrates what can be achieved if resources are targeted at providing individualised post-diagnostic support, particularly where there are service delivery gaps
Post-collisional tectono-magmatic evolution, crustal fertilization, and ore genesis: the late Variscan metallogenic stages in Sardinia
No full textThe Variscan post-collisional tectonic and magmatic events were critical for ore deposits in the Paleozoic
massifs of Europe. In Sardinia, two main types of Variscan ore deposits can be recognized: (1) “orogenic”,
structurally-controlled deposits associated with shear zones and extensional structures; (2) granite intrusion
hosted/related deposits. Both types are unevenly distributed in the Paleozoic basement and in the Sardinian
batholith, being much more abundant in Southern Sardinia. “Orogenic” deposits include As-Au±Sb ± W and
Zn-Cu-Pb-Ag vein systems hosted in greenschist facies metamorphics. They result from multiple mineralization
stages from fluids of mixed (but dominantly metamorphic) origin at different structural levels in the nappe
stack of the Variscan front, during the post-collisional extension. Large-scale antiformal structures were traps
for fluids; base metal and As-Au-rich deposits prevail in deeper structural zones, whereas Sb-W (Au) deposits
are related with shallower extensional structures.
Granite-hosted/related deposits consist of Mo ± Cu greisens, Pb-Zn-Cu-Fe±Sn± W±Bi±F and Pb-Zn-Cu-
Fe±REE skarns, and W-Sn-Mo-Bi (±Te±Au) and Pb-Zn-F-Ba veins, also associated in magmatic-hydrothermal
systems. Most intrusion-hosted/related ores may be bracketed into the latest and narrow (290-285) Ma growth
stages of Sardinian Batholith. They are more abundant in southern Sardinia, associated to multiple suites of
F-rich granites, including a suite of Sn-W-Mo (Bi, In)-bearing, “rare metals” granites belonging to an ilmenite
rock-series (Naitza et al., 2017).
As evidenced in recent literature (Cocco et al., 2018; Secchi et al., 2022), the Paleozoic basement of
Sardinia is made of micro-terranes assembled by large-scale shear zones in the post-collisional Variscan
stages, when both “orogenic” and granite-related ores resulted from a wide metallogenic fertilization of the
Sardinian crustal segment. These events may be tentatively framed in a context of lithospheric delamination,
which triggered production and crustal-scale migration of magmas and fluids along lithospheric shear zones,
widely redistributing ore-forming elements, including (a) new contributions linked to partial melting of
different crustal levels and to crust/mantle interactions, and (b) widespread recycling of elements present in
the pre-Variscan successions (e.g., Pb, Zn, Ba from Cambrian MVT ores of SW Sardinia; REE from Upper
Ordovician paleoplacers in Eastern Sardinia). Variscan crustal fertilization was essential for the post-Variscan
metallogenic stages (Middle Permian-Triassic?), during which new and widespread fluid circulation in the
basement produced, in the context of the breakup of Pangea and the opening of the Tethys (Burisch et al.,
2022), different kinds of low-temperature polymetallic hydrothermal ores (Pb-Zn ± Cu±Ag; Ni-Co-As-Bi-Ag;
Ba-F ± Pb ± Ag), often directly remobilizing previous magmatic-hosted/related ones
Diasporas and democratization in the post-communist world
No full textIf diaspora communities are socialized with democratic values in Western societies, they could be expected to be sympathetic to the democratization of their home countries. However, there is a high degree of variation in their behavior. Contrary to the predominant understanding in the literature that diasporas act in exclusively nationalist ways, this article argues that they do engage with the democratization of their home countries. Various challenges to the sovereignty of their homelands explain whether diasporas involve with procedural or liberal aspects of democratization. Drawing evidence from the activities of the Ukrainian, Serbian, Albanian and Armenian diasporas after the end of communism, I argue that unless diasporas are linked to home countries that enjoy both international legal and domestic sovereignty, they will involve only with procedural aspects of democratization. Diasporas filter international pressure to democratize post-communist societies by utilizing democratic procedures to advance unresolved nationalist goals
A Model for Analysing One-to- One teaching in the Maths Recovery Program
No full textThis study was proposed as a first step to understanding teaching characteristics\ud
particularly suited to one-to-one teaching in the Maths Recovery\ud
Program. The teaching sessions of four teachers of Maths Recovery\ud
were analysed to develop an experimental model of teaching\ud
characteristics. Videotaped excerpts from teaching sessions of the Maths\ud
Recovery Research Project were used in the analysis.\ud
The experimental model of teaching characteristics draws on several\ud
areas of research literature including Brophy and Good, 1986;\ud
Cazden, 1986; Goodman and Goodman, 1990; Lyons, Pinnell and\ud
DeFord, 1993; Mellin-Olsen, 1991; von Glasersfeld, 1990; Vygotsky,\ud
1934/1962-1930/1978; Wood, 1990; Wright, 1995; and Yackel, 1990.\ud
The characteristics identified were scaffolding, double bind, illusion\ud
of competence, preformulating and reformulating questions, post\ud
question wait-time, vague or ambiguous questioning, questioning and\ud
prompting, and communication. Scaffolding refers to the gradual withdrawal\ud
of adult control as a function of children’s increasing mastery of\ud
a given task. A double bind is complementary to scaffolding. A double\ud
bind produces dependence and results from repetition of a learning\ud
task after a child experiences difficulty in understanding the task. An\ud
illusion of competence refers to when the teacher and student produce\ud
a solution together, with the student following teacher directives.\ud
Preformulating and reformulating questions occurs when the teacher\ud
prefaces the question with utterances which serve to orient the children\ud
to the relevant area of experience and establish as shared knowledge\ud
between the teacher and child notions essential to answer the question.\ud
Reformulating refers to the simplification of a question when the\ud
initial answer is wrong. The teacher knowingly or unknowingly reduces\ud
the cognitive value of the question. Post question wait-time refers to\ud
the length of time that a child has to respond to a question. Vague or\ud
ambiguous questioning relates to when teachers ask questions, which\ud
are vague or ambiguous to the child, and they are unable to respond to\ud
the question. Questioning and prompting occurs when a teacher observes\ud
closely what a child is doing and decides the appropriate question\ud
or prompt which will help a child become a more independent\ud
problem solver and less dependent on the teacher. Communication\ud
refers to what is suitable and unsuitable communication in one-to-one\ud
teaching.\ud
8\ud
The methods used to develop and test the experimental model\ud
draw on Vygotsky’s (1930/1978) methodological principles and Cobb\ud
and Whitenack’s (1996) methodology for longitudinal analyses of data\ud
on teaching in the form of videotaped recordings and transcripts. In\ud
Phase One of the study characteristics of teaching were identified separately\ud
from each other and used to build a preliminary model of characteristics\ud
of one- to-one teaching. These observations were compared\ud
and contrasted with the research literature until a fit was obtained. The\ud
data was then compared with subsequent data until a newly formed\ud
model of characteristics in one-to-one teaching evolved. Phase Two\ud
was undertaken in order to test the usefulness of the experimental model.\ud
The study found that the research literature which refers to the\ud
classroom setting remains a suitable guide to analysing one-to-one teaching.\ud
More study of one-to-one teaching with the focus on the teacher is\ud
needed to evaluate directly as opposed to indirectly via student achievement,\ud
the effectiveness of one-to-one teaching. In one-to-one teaching\ud
programs, teachers need to be aware of appropriate and inappropriate\ud
characteristics of one-to-one teaching and possible effects on students.\ud
Scaffolding, post question wait-time, questioning and prompting support\ud
the underlying principles of Maths Recovery Teaching. The theory\ud
of a zone of proximal development as a method for understanding the\ud
actual and potential development of a child can be usefully applied to\ud
the Maths Recovery Program
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
ICF Core Sets for individuals with spinal cord injury in the early post-acute context
No full textStudy design: A formal decision-making and consensus process integrating evidence gathered from preparatory studies was followed.Objectives: The aim of this study was to report on the results of the consensus process to develop the first version of a Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set and a Brief ICF Core Set for individuals with spinal cord injury (SCI) in the early post-acute context.Setting: The consensus conference took place in Switzerland. Preparatory studies were performed worldwide.Methods: Preparatory studies included an expert survey, a systematic literature review, a qualitative study and empirical data collection involving people with SCI. ICF categories were identified in a formal consensus process by international experts from different backgrounds.Results: The preparatory studies identified a set of 531 ICF categories at the second, third and fourth levels. From 30 countries, 33 SCI experts attended the consensus conference (11 physicians, 6 physical therapists, 5 occupational therapists, 6 nurses, 3 psychologists and 2 social workers). Altogether 162 second-, third- or fourth-level categories were included in the Comprehensive ICF Core Sets with 63 categories from the component Body Functions, 14 from Body Structures, 53 from Activities and Participation and 32 from Environmental Factors. The Brief Core Set included a total of 25 second-level categories with 8 on Body Functions, 3 on Body Structures, 9 on Activities and Participation, and 5 on Environmental Factors.Conclusion: A formal consensus process-integrating evidence and expert opinion based on the ICF led to the ICF Core Sets for individuals with SCI in the early post-acute context. Further validation of this first version is needed
Snapshot Culture. The Photographic Experience in the Post-Medium Age
No full textLo studio della fotografia è stato a lungo appannaggio dell’ambito artistico-estetico, o tutt’al più oggetto strumentale di investigazioni filosofiche. Con l’avvento delle tecnologie digitali la fotografia ha invece guadagnato progressiva centralità negli studi sui media e sulla comunicazione. Dagli anni 2000 in avanti una serie di eventi sociali e tecnologici l’ha resa più accessibile, ubiqua, personale, economica, democratica, immediata e condivisa, e ha aperto la strada a una nuova esperienza fotografica. Nonostante sia uno dei più antichi media moderni, la fotografia continua oggi a dare visibilità e forma alle nostre vite, a potenziare la nostra visione biologica ed ad accrescere la nostra immaginazione visiva. I curatori di questo monografico introducono l’espressione “snapshot culture” per riferirsi al complesso dei mutamenti estetici e pratici dell’esperienza fotografica, con l’intento di evidenziarne gli aspetti rilevanti e innovativi, pur senza sottacere le ricadute problematiche. La “snapshot culture” è caratterizzata da una duplice dinamica: da un lato la persistenza dei tratti originari e costitutivi dell’esperienza fotografica, dall’altro la modulazione di nuove opportunità offerte dalle innovazioni tecnologiche e dai cambiamenti sociali, nello scenario di una più ampia “condizione post-mediale”. I contributi raccolti offrono un’esplorazione critica della “persistenza” della fotografia nell’esperienza contemporanea, sia attraverso l’analisi di oggetti e fenomeni concreti (dal selfie alla GIF animata, da Instagram alla fotografia computazionale...), sia attraverso la rilettura e la revisione degli approcci interpretativi finora utilizzati per comprenderla.For a long time, the study of photography has been a part of Art studies or a mere object of philosophical investigations. Yet, after the advent of digital technologies it progressively became central in Media and Communication studies. From the 2000s onwards, various social and technological events made photography more accessible, ubiquitous, public, cheap, democratic, immediate and shared than ever before, paving the way to a renewal of photographic experience. New objects, formats, devices, practices and uses emerged as specific traits of a ‘performative’ photographic agency. This emergence is allowed by the fact that photography, despite being one of the most ancient media, still shapes our lives, empowers our biological vision, and enhances our imaginative visual practices. The editors of this issue propose the term ‘snapshot culture’ to refer to the combination of technological, aesthetic and practical shifts in contemporary photographic experience. Snapshot culture is characterized by a twofold dynamic: the persistence of the original traits of the photographic experience as it emerged and developed, coupled with the modulation of new opportunities offered by technological improvements and social changes. Indeed, the digitalization of photographic aesthetics and related media practices provides an ideal case for studying some of the most challenging developments in visual media aesthetics within the broader landscape of the post-medium condition and for reflecting on how photography theory has responded to such challenges in the post-theory era. This special issue offers a critical investigation of photography’s ‘persistence’ in the media experience through both an analysis of concrete objects and phenomena (e.g. selfies, animated GIFs, social networking, computational photography) and the refinement of theoretical approaches to photography
Post-Cinema Ecology
No full textInstead of developing the general theme of the immersive experience, Francesco Casetti and Andrea Pinotti exemplify it by focusing specifically on Alejandro G. Iñárritu’s Carne y arena, an interactive virtual reality installation presented at the 2017 Cannes Film Festival, insofar as it testifies to the formal and spectatorial transformations that are rightly referred to as post-cinema. More generally, emphasizing the characteristics of “unframedness, presentness, and immediateness,” this kind of work
draws our attention to the phenomenology of the film experience. Casetti and Pinotti propose going beyond phenomenology (and ontology) with the project of an iconic ecology based on the concept of phaneron, the appearance as it is perceived for itself
Results of the Heart Protection Study: Can we still assume a class effect?
No full textStatins share several common features including the mechanism of action, i.e. inhibition of HMG-CoA reductase, as well as LDL-cholesterol (LDL-C) and triglyceride lowering properties. However, statins show minor differences in chemical structure, lipophilicity that could translate into a different pharmacological properties. For example, simvastatin exerted a more favorable effect on HDL-C levels than did atorvastatin when higher doses of the two drugs were compared. Finally, the major considerations to chose between statins for CVD patient therapy include clinical benefits and safety (i.e. evidence-based medicine). Primary prevention trials with pravastatins and lovastatin and secondary prevention trials with pravastatin, fluvastatin and simvastatin have established the clinical benefits of statins. In addition, HPS study was designed to investigate the benefits of simvastatin 40 mg in a broad range of patients at high risk for heart disease including women, the elderly and those with a history of hearth attacks, diabetes, hypertension or vascular disease. The results show the ability of simvastatin to reduce all causes of mortality, vascular death and cardiovascular morbidity. The trial also confirms the safety of simvastatin 40 mg although 60% of patients were receiving additional pharmacological treatment. In summary, it appears that statins are not the same and the choice of the more appropriate statin in high-risk patients should be driven by the evidence-based medicine both in terms of safety and efficacy
