Bar-holding prosthetic limb
A prosthetic device for below-the-elbow amputees is disclosed. The device has a removable effector, which is attached to the end of an arm cuff. The effector is comprised of a pair of C-shaped members that are oriented so as to face each other. Working in concert, the C-shaped members are able to hold a bar such as a chainsaw handle. A flat spring is fitted around the C-shaped members to hold them together
Scalable Bayesian modeling, monitoring and analysis of dynamic network flow data
Traffic flow count data in networks arise in many applications, such as
automobile or aviation transportation, certain directed social network
contexts, and Internet studies. Using an example of Internet browser traffic
flow through site-segments of an international news website, we present
Bayesian analyses of two linked classes of models which, in tandem, allow fast,
scalable and interpretable Bayesian inference. We first develop flexible
state-space models for streaming count data, able to adaptively characterize
and quantify network dynamics efficiently in real-time. We then use these
models as emulators of more structured, time-varying gravity models that allow
formal dissection of network dynamics. This yields interpretable inferences on
traffic flow characteristics, and on dynamics in interactions among network
nodes. Bayesian monitoring theory defines a strategy for sequential model
assessment and adaptation in cases when network flow data deviates from
model-based predictions. Exploratory and sequential monitoring analyses of
evolving traffic on a network of web site-segments in e-commerce demonstrate
the utility of this coupled Bayesian emulation approach to analysis of
streaming network count data.Comment: 29 pages, 16 figure
Rotationally actuated prosthetic helping hand
A prosthetic device has been developed for below-the-elbow amputees. The device consists of a cuff, a stem, a housing, two hook-like fingers, an elastic band for holding the fingers together, and a brace. The fingers are pivotally mounted on a housing that is secured to the amputee's upper arm with the brace. The stem, which also contains a cam, is rotationally mounted within the housing and is secured to the cuff, which fits over the amputee's stump. By rotating the cammed stem between the fingers with the lower arm, the amputee can open and close the fingers
Integrating subjective recovery and stigma resistance in individuals with schizophrenia: a narrative review and theoretical integration
Stigmatised attitudes are known to be associated with negative outcomes in schizophrenia, yet there is little focus on the role of stigma in the recovery process. Attempts to develop interventions to reduce self-stigma in schizophrenia have not been found effective. This paper presents a theoretical integration based on a narrative review of the literature. PsycINFO, Medline and Embase databases were searched up to the 11th December 2023. Studies were included if they were: i) empirical studies using qualitative, quantitative or mixed methods studies investigating mental health stigma; ii) included participants based in the United Kingdom, fluent in English, between the ages of 16 and 70, meeting criteria for a schizophrenia spectrum diagnosis. Fourteen studies were included. In Part 1, we propose a novel theoretical model derived from a synthesis of service-user perspectives on the relationship between stigma and schizophrenia. Stigmatised attitudes were commonly perceived to be caused by a lack of education and further exacerbated by disinformation primarily through the media and cultural communities. Stigma led to negative self-perceptions, negative emotional responses, social isolation and increased symptom severity, ultimately acting as a barrier to recovery. In Part 2, we identify several factors that ameliorate the impact of stigma and promote clinical and subjective recovery among service-users: education, empowerment, self-efficacy, self-acceptance, hope and social support. We argue that the notion of stigma resistance may be helpful in developing new interventions aimed at promoting recovery in individuals with schizophrenia. Wider implications are discussed and recommendations for future research and practice are explored.</p
Effectiveness of group-based self-management education for individuals with Type 2 diabetes:A systematic review with meta-analyses and meta-regression
Aims:
Patient education for the management of Type 2 diabetes can be delivered in various forms, with the goal of promoting and supporting positive self-management behaviours. This systematic review aimed to determine the effectiveness of group-based interventions compared with individual interventions or usual care for improving clinical, lifestyle and psychosocial outcomes in people with Type 2 diabetes.
Methods:
Six electronic databases were searched. Group-based education programmes for adults with Type 2 diabetes that measured glycated haemoglobin (HbA1c) and followed participants for ≥ 6 months were included. The primary outcome was HbA1c, and secondary outcomes included fasting blood glucose, weight, body mass index, waist circumference, blood pressure, blood lipid profiles, diabetes knowledge and self-efficacy.
Results:
Fifty-three publications describing 47 studies were included (n = 8533 participants). Greater reductions in HbA1c occurred in group-based education compared with controls at 6–10 months [n = 30 studies; mean difference (MD) = 3 mmol/mol (0.3%); 95% confidence interval (CI): −0.48, −0.15; P = 0.0002], 12–14 months [n = 27 studies; MD = 4 mmol/mol (0.3%); 95% CI: −0.49, −0.17; P < 0.0001], 18 months [n = 3 studies; MD = 8 mmol/mol (0.7%); 95% CI: −1.26, −0.18; P = 0.009] and 36–48 months [n = 5 studies; MD = 10 mmol/mol (0.9%); 95% CI: −1.52, −0.34; P = 0.002], but not at 24 months. Outcomes also favoured group-based education for fasting blood glucose, body weight, waist circumference, triglyceride levels and diabetes knowledge, but not at all time points. Interventions facilitated by a single discipline, multidisciplinary teams or health professionals with peer supporters resulted in improved outcomes in HbA1c when compared with peer-led interventions.
Conclusions:
Group-based education interventions are more effective than usual care, waiting list control and individual education at improving clinical, lifestyle and psychosocial outcomes in people with Type 2 diabetes.No Full Tex
Border City
Thesis submitted by Gabriel Thomas Jewell-Vitale for completion of the B.Arch degree. Border city does not acknowledge border as a line, but as a territory. Border city opportunistically looks toward the merging of cultures and the exchange of people and flows. Border city is both port, souk, caravanserai, city and border crossing. Border city is a framework for a borderless city
