Optimal Controlled Teleportation
We give the analytic expressions of maximal probabilities of successfully
controlled teleportating an unknown qubit via every kind of tripartite states.
Besides, another kind of localizable entanglement is also determined.
Furthermore, we give the sufficient and necessary condition that a three-qubit
state can be collapsed to an EPR pair by a measurement on one qubit, and
characterize the three-qubit states that can be used as quantum channel for
controlled teleporting a qubit of unknown information with unit probability and
with unit fidelity.Comment: 4 page
Transcultural, transdiagnostic, and concurrent validity of a revised Metacognitions about Symptom Control Scale
Anxiety and depression add to the burden of Chronic Fatigue Syndrome (CFS), Fibromyalgia (FM), and Type 1 Diabetes Mellitus (T1DM). Metacognitions play a role in this distress. The Metacognitions about Symptoms Control Scale (MaSCS) measures metacognitive beliefs regarding symptoms but has weaknesses. The current study created a revised MaSCS (MaSCS-R) in English, German, and Arabic versions using CFS, FM, and T1DM samples, and examined the transcultural, transdiagnostic, and concurrent validity of metacognitions about symptom control. This study used data from a total of 563 participants clinically diagnosed with CFS (n = 124; English), FM (n = 348; German), or T1DM (n = 91; Lebanese). CFS and FM data had been used in earlier published studies but were subjected to new analyses. CFS data was used to create the English version of the MaSCS-R, and FM and T1DM data for German and Arabic versions. Metacognitions about worry, anxiety, depression, and symptom severity were measured. The three MaSCS-R versions, consisting of two factors (each with four items), had adequate psychometric properties, possessing configural and metric invariance. Metacognitive factors were associated with distress and symptom severity in all three samples. Metacognitions about symptom control have transcultural, transdiagnostic, and concurrent validity.

The impact of bereavement support on wellbeing: a comparative study between Australia and Ireland
Background: There is a dearth of national and international data on the impact of social support on physical, mental, and financial outcomes following bereavement. Methods: We draw from two large, population-based studies of bereaved people in Australia and Ireland to compare bereaved peopleās experience of support. The Australian study used a postal survey targeting clients of six funeral providers and the Irish study used telephone interviews with a random sample of the population. Results: Across both studies, the vast majority of bereaved people reported relying on informal supporters, particularly family and friends. While sources of professional help were the least used, they had the highest proportions of perceived unhelpfulness. A substantial proportion, 20% to 30% of bereaved people, reported worsening of their physical and mental health and about 30% did not feel their needs were met. Those who did not receive enough support reported the highest deterioration in wellbeing. Discussion: The compassionate communities approach, which harnesses the informal resources inherent in communities, needs to be strengthened by identifying a range of useful practice models that will address the support gaps. Ireland has taken the lead in developing a policy framework providing guidance on level of service provision, associated staff competencies, and training needs

Exploring the Support Needs of Family Caregivers of Patients with Brain Cancer Using the CSNAT: A Comparative Study with Other Cancer Groups
A substantial burden is placed on family caregivers of patients diagnosed with brain cancers. Despite this, the support needs of the caregivers are often under-recognised and not addressed adequately in current routine and patient centred clinical care. The Care Support Needs Assessment Tool (CSNAT) is a validated instrument designed to systematically identify and address caregiver needs. It has been trialled in an Australian palliative care community setting using a stepped wedge cluster design involving 322 family carers of terminally ill patients. The current article reports on a subset from this trial, 29 caregivers of patients with primary brain cancer, and compares their profile and outcomes to those of other cancer groups. Caregiver strain was assessed using the Family Appraisal of Caregiving Questionnaire, caregiver physical and mental wellbeing using SF12 and caregiver workload using a questionnaire on support with activities of daily living (ADL). In comparison to caregivers of patients with all other cancers, the primary brain cancer group had significantly higher levels of caregiver strain, lower levels of mental wellbeing and a higher level of ADL workload. Their physical wellness also deteriorated significantly over time.An action plan approach led to practical solutions for addressing highlighted concerns. Four themes evolved from the family caregiversā feedback interviews: The extremely challenging caregiver experience with brain cancer; the systematic and practical approach of the CSNAT during rapid changes; connection with health professionals, feeling acknowledged and empowered; and timely advice and assurance of support during the caregiving journey. This preliminary study has demonstrated that the CSNAT provides a practical and useful tool for assessing the support needs of family caregivers of patients with brain cancer and has provided the basis for a larger scale, longitudinal study that allows a more detailed characterisation of the evolving caregiver needs at different stages of the disease
An assets-based approach to bereavement care
A survey of bereaved clients of four funeral providers in Australia confirms a public health model predicting that over half the group would demonstrate low risk of complicated grief, another third moderate risk, while a small minority would meet the criteria for prolonged grief disorder. The survey also shows differing patterns of need and sources of support for each of the three groups. While our findings support targeting the bereavement care provided by health services, our primary interest is in the care received by most bereaved people. Some is provided in the community through the everyday activities of healthcare professionals. Most comes from a range of people already involved in the everyday lives of those recently bereaved. We contend that the most effective way to provide bereavement care is to support these āeveryday assetsā, ensuring that their care is recognised, appreciated, and not disrupted by over-reach from professional services
Product Service System Innovation in the Smart City
Product service systems (PSS) may usefully form part of the mix of innovations necessary to move society toward more sustainable futures. However, despite such potential, PSS implementation is highly uneven and limited. Drawing on an alternate socio-technical perspective of innovation, this paper provides fresh insights, on among other things the role of context in PSS innovation, to address this issue. Case study research is presented focusing on a use orientated PSS in an urban environment: the Copenhagen city bike scheme. The paper shows that PSS innovation is a situated complex process, shaped by actors and knowledge from other locales. It argues that further research is needed to investigate how actors interests shape PSS innovation. It recommends that institutional spaces should be provided in governance landscapes associated with urban environments to enable legitimate PSS concepts to co-evolve in light of locally articulated sustainability principles and priorities
Why and how the work of Motor Neurone Disease Associations matters before and during bereavement: a consumer perspective
Background: Studies on the experiences of consumers with Motor Neurone Disease Associations at end of life and bereavement are lacking, and their role and capability within the broader sectors of health and disability are unknown. Objectives: To ascertain the experiences and views of bereaved motor neurone disease caregivers with Motor Neurone Disease Associations about service gaps and needed improvements before and during bereavement and to propose a model of care that fits with consumer preferences and where Motor Neurone Disease Associations are effective enablers of care. Methods: A national bereavement survey was facilitated in 2019 by all Motor Neurone Disease Associations in Australia. A total of 363 respondents completed the section on support provided by Motor Neurone Disease Associations. A mixed-method design was used. Results: Respondents were generally positive about support received before bereavement (73-76%), except for emotional support (55%). Positive experiences related to the following: information, equipment advice/provision, advocacy/linking to services, showing empathy/understanding, personal contact and peer social support. Negative experiences included lack of continuity in case management and contact, perceived lack of competence or training, lack of emotional support and a lack of access to motor neurone disease services in rural areas. Suggested improvements were as follows: more contact and compassion at end of life and postdeath; better preparation for end of life; option of discussing euthanasia; providing referrals and links for counseling; access to caregiver support groups and peer interaction; provision of a genuine continuum of care rather than postdeath abandonment; guidance regarding postdeath practicalities; and more access to bereavement support in rural areas. Conclusion: This study provides consumer perspectives on driving new or improved initiatives by Motor Neurone Disease Associations and the need for a national standardised approach to training and service delivery, based on research evidence. A public health approach to motor neurone disease end-of-life care, of international applicability, is proposed to address the needs and preferences of motor neurone disease consumers, while supporting the capability of Motor Neurone Disease Associations within a multidisciplinary workforce to deliver that care
