Designing for wellbeing in late stage dementia
Get PDFThis paper presents research that is developing new ways of supporting the wellbeing of people with late stage dementia through the development of playful objects. The LAUGH project is an international AHRC funded design research project that is using qualitative and participatory approaches to inform innovative concepts for new playful artefacts to stimulate fun, joy and in the moment pleasure for people living with dementia. The research is partnered by Gwalia Cyf and supported by Age Cymru and Alzheimer’s Society, including people living with dementia from their Service User Review Panels (SURP).
Data presented is informed by three pre-design development workshops in which a multidisciplinary group of experts in the fields of dementia care and design have contributed their professional experience. This paper specifically focuses on data from the third of these workshops exploring procedural memory in relation to hand-use and craft making.
This paper contends that hand-use, gesture and haptic sensibilities can provide access to procedural and emotional memories, which are retained even into the late stages of the disease. Craft and making activities learned in earlier life, provide rhythmic patterns of hand activity that can enhance wellbeing by supporting in the moment sensory experience, competency and reaffirmation of personhood. Playful activities provide a person with dementia freedom to explore, learn and have positive experiences even when cognitive function and memory recall is severely impaired.
Future planned workshops will see the iterative development of prototype designs and their evaluation in ‘live labs’ with people living with late stage dementia
The Perceived Size and Shape of Objects in Peripheral Vision
Get PDFLittle is known about how we perceive the size and shape of objects in far peripheral vision. Observations made during an artistic study of visual space suggest that objects appear smaller and compressed in the periphery compared with central vision. To test this, we conducted three experiments. In Experiment 1, we asked participants to draw how a set of peripheral discs appeared when viewed peripherally without time or eye movement constraints. In Experiment 2, we used the method of constant stimuli to measure when a briefly presented peripheral stimulus appeared bigger or smaller compared with a central fixated one. In Experiment 3, we measured how accurate participants were in discriminating shapes presented briefly in the periphery. In Experiment 1, the peripheral discs were reported as appearing significantly smaller than the central disc, and as having an elliptical or polygonal contour. In Experiment 2, participants judged the size of peripheral discs as being significantly smaller when compared with the central disc across most of the peripheral field, and in Experiment 3, participants were quite accurate in reporting the shape of the peripheral object, except in the far periphery. Our results show that objects in the visual periphery are perceived as diminished in size when presented for long and brief exposures, suggesting diminution is an intrinsic feature of the structure of the visual space. Shape distortions, however, are reported only with longer exposures
Music regulators in two string quartets: A comparison of communicative behaviors between low- and high-stress performance conditions
Get PDFIn ensemble performances, group members use particular bodily behaviors as a sort of “language” to supplement the lack of verbal communication. This article focuses on music regulators, which are defined as signs to other group members for coordinating performance. The following two music regulators are considered: body gestures for articulating attacks (a set of movements externally directed that are used to signal entrances in performance) and eye contact. These regulators are recurring observable behaviors that play an important role in non-verbal communication among ensemble members. To understand how they are used by chamber musicians, video recordings of two string quartet performances (Quartet A performing Bartók and Quartet B performing Haydn) were analyzed under two conditions: a low stress performance (LSP), undertaken in a rehearsal setting, and a high stress performance (HSP) during a public recital. The results provide evidence for more emphasis in gestures for articulating attacks (i.e., the perceived strength of a performed attack-type body gesture) during HSP than LSP. Conversely, no significant differences were found for the frequency of eye contact between HSP and LSP. Moreover, there was variability in eye contact during HSP and LSP, showing that these behaviors are less standardized and may change according to idiosyncratic performance conditions. Educational implications are discussed for improving interpersonal communication skills during ensemble performance
Exercise-induced improvements in liver fat and endothelial function are not sustained 12 months following cessation of exercise supervision in non-alcoholic fatty liver disease (NAFLD)
Get PDFAIMS:
Supervised exercise reduces liver fat and improves endothelial function, a surrogate of cardiovascular disease risk, in non-alcoholic fatty liver disease (NAFLD). We hypothesised that after a 16-week supervised exercise program, patients would maintain longer-term improvements in cardiorespiratory fitness, liver fat and endothelial function.
MATHERIALS AND METHODS:
Ten NAFLD patients [5/5 males/females, age 51±13years, BMI 31±3 kg.m2 (mean±s.d.)] underwent a 16-week supervised moderate-intensity exercise intervention. Biochemical markers, cardiorespiratory fitness (VO2peak), subcutaneous, visceral and liver fat (measured by magnetic resonance imaging and spectroscopy respectively) and brachial artery flow-mediated dilation (FMD) were assessed at baseline, after 16 weeks supervised training and 12-months after ending supervision.
RESULTS:
Despite no significant change in body weight, there were significant improvements in VO2peak [6.5 ml.kg−1.min−1 (95% CI 2.8, 10.1); P=0.003], FMD [2.9% (1.5, 4.2); P=0.001], liver transaminases (P0.05) and liver fat [1.4% (−13.0, 15.9); P=0.83] were not significantly different from baseline.
CONCLUSIONS:
Twelve months following cessation of supervision, exercise-mediated improvements in liver fat and other cardiometabolic variables had reversed with cardiorespiratory fitness at baseline levels. Maintenance of high cardiorespiratory fitness and stability of body weight are critical public health considerations for the treatment of NAFLD
3D modeling and motion parallax for improved videoconferencing
Get PDFWe consider a face-to-face videoconferencing system that uses a Kinect camera at each end of the link for 3D modeling and an ordinary 2D display for output. The Kinect camera allows a 3D model of each participant to be transmitted; the (assumed static) background is sent separately. Furthermore, the Kinect tracks the receiver’s head, allowing our system to render a view of the sender depending on the receiver’s viewpoint. The resulting motion parallax gives the receivers a strong impression of 3D viewing as they move, yet the system only needs an ordinary 2D display. This is cheaper than a full 3D system, and avoids disadvantages such as the need to wear shutter glasses, VR headsets, or to sit in a particular position required by an autostereo display. Perceptual studies show that users experience a greater
sensation of depth with our system compared to a typical 2D videoconferencing system
Assessment of platelet function in patients with stroke using multiple electrode platelet aggregometry: a prospective observational study
No full textBackground
There is a link between high on-treatment platelet reactivity (HPR) and adverse vascular events in stroke. This study aimed to compare multiple electrode platelet aggregometry (MEA), in healthy subjects and ischaemic stroke patients, and between patients naive to antiplatelet drugs (AP) and those on regular low dose AP. We also aimed to determine prevalence of HPR at baseline and at 3–5 days after loading doses of aspirin.
Methods
Patients with first ever ischaemic stroke were age and sex-matched to a healthy control group. Three venous blood samples were collected: on admission before any treatment given (baseline); at 24 h and 3–5 days after standard treatment. MEA was determined using a Mutliplate® analyser and agonists tested were arachidonic acid (ASPI), adenosine diphosphate (ADP) and collagen (COL).
Results
Seventy patients (mean age 73 years [SD 13]; 42 men, 28 women) were age and sex-matched to 72 healthy subjects. Thirty-three patients were on antiplatelet drugs (AP) prior to stroke onset and 37 were AP-naive. MEA results for all agonists were significantly increased in AP-naive patients compared to healthy subjects: ADP 98 ± 31 vs 81 ± 24, p < 0.005; ASPI 117 ± 31 vs 98 ± 27, p < 0.005; COL 100 ± 25 vs 82 ± 20, p < 0.005. For patients on long term AP, 33% (10/30) of patients were considered aspirin-resistant. At 3–5 days following loading doses of aspirin, only 11.1% were aspirin resistant based on an ASPI cut-off value of 40 AU*min.
Conclusions
Many patients receiving low dose aspirin met the criteria of aspirin resistance but this was much lower at 3–5 days following loading doses of aspirin. Future studies are needed to establish the causes of HPR and potential benefits of individualizing AP treatment based on platelet function testing
Risk factors for lower leg, ankle and foot injuries during basic military training in the Maltese Armed Forces
Get PDFObjectives -
Basic military training is physically and psychologically demanding placing recruits at high risk of injury and premature discharge. This study aimed to identify risk factors for lower leg, ankle and foot injury in Maltese military recruits during basic training.
Design -
This was a prospective cohort study.
Setting -
An armed forces barracks.
Participants -
127 recruits commencing one basic military training course agreed to participate in the study. The cohort comprised 114 males and 13 females with a mean age of 21.7 ± 2.4 years.
Main outcome measures -
All injuries to the lower leg, ankle and foot were recorded using the Orchard Sports Injury Classification System. Injuries were analysed for associations with fitness scores, smoking status, body mass index and foot type.
Results -
A total of 34 (26.2%) recruits sustained at least one injury, with 10 recruits (7.9%) terminating their training prematurely (three due to musculoskeletal injury). Smoking history, body mass index and foot type were not associated with injury risk. Lower fitness levels at the commencement of basic military training compared with fitness levels measured six months prior, were associated with higher injury risk.
Conclusions -
Lower fitness at the commencement of basic training was associated with higher injury risk in army recruits. Thus, conditioning programmes aimed at improving recruit fitness should be considered within an injury prevention strategy
Facing the Spectator
Get PDFWe investigated the familiar phenomenon of the uncanny feeling that represented people in frontal pose invariably appear to ‘‘face you’’ from wherever you stand. We deploy two different methods. The stimuli include the conventional one—a flat portrait rocking back and forth about a vertical axis—augmented with two novel variations. In one alternative, the portrait frame rotates whereas the actual portrait stays motionless and fronto-parallel; in the other, we replace the (flat!) portrait with a volumetric object. These variations yield exactly the same optical stimulation in frontal view, but become grossly different in very oblique views. We also let participants sample their momentary awareness through ‘‘gauge object’’ settings in static displays. From our results, we conclude that the psychogenesis of visual awareness maintains a number—at least two, but most likely more—of distinct spatial frameworks simultaneously involving ‘‘cue–scission.’’ Cues may be effective in one of these spatial frameworks but ineffective or functionally different in other ones
Validation of the Spanish version of Soane's ISA Engagement Scale
Get PDFThe interest in the study of engagement in the academic field can be seen through the increasing number of results in Google Scholar and in Scopus, going from barely 20 results between 2000 and 2005 to more than 500 in Scopus and more than 1100 in Google Scholar between 2011 and 2015. Soane et al. (2012) propose a unified theoretical framework as the basis of the psychological mechanism of engagement, grounded on the approach of Kahn (1990). The aim of this paper is to analyze the psychometric properties of the Spanish version of the ISA engagement scale in a sample of 477 employees of the administration and services sector in a Spanish public university. Keeping the original design of the English version of the scale, the proposed factorial structure is validated with the good fit of the data according to the revised goodness of fit indices; reliability and the results of the analysis of construct validity
Observation as a method to enhance collective efficacy: An integrative review
Get PDFObjectives
This review provides an integrative argument for the use of observation as an intervention to manipulate individual collective efficacy beliefs in sports teams.
Design
An exploration of the conceptual and empirical evidence underpinning observation-based interventions for increasing collective efficacy.
Method
A presentation of reflections on the following. First, we reflect on existing techniques used to increase self- and collective efficacy beliefs. Second, we consider collective efficacy in the context of observational learning and the various modeling techniques employed in the sports and motor performance literature. Third, we highlight relevant literature from neuroscience, outlining the analogous neural pathways evident for social cognition (i.e., collective efficacy) and observation.
Results
This review presents a case for the use of observation interventions to manipulate collective efficacy, drawing upon social psychological frameworks of human behavior, the observation-based literature, and contemporary understanding of brain and behavior.
Conclusions
Observation-based interventions are suited for collective efficacy manipulation in sport. There is a need to advance understanding of this relationship in order to maximize improvements in collective efficacy across group contexts
