    Full text link
    The purpose of this qualitative study was to illustrate how the identity of Chinese older adults who lost their only child changed after the traumatic event in the context of unique culture and policy settings. The individuals studied were 14 adults over the age of 50. Each respondent was interviewed concerning his or her post-loss experiences. Results indicated that these bereaved parents are not only deeply impacted by the loss of the most loved one, but are also stigmatized by the culture and victimized by the one-child policy. The collective identity as shiduer is defined not only by personal grief but also by cultural uniqueness and the unintended consequences of the one-child policy

    Most modern grief theories and clinical working models are constructed in the context of Western culture, and the effectiveness or explanatory power of those theories and models have not been fully tested in other cultures, especially through a more complex interactive model. The current study focuses on the role of attachment style, coping strategy, social support and spirituality on older bereaved parents’ grief. It also explores if differences in age, gender, causes of the child’s death, time since the death have a differential effect on parental grief. The purpose of this study was to test the main factors effectively mediating or aggregating the extent of Chinese parents’ grief following their only child’s death. The sample of this study consisted of 206 Chinese older parents whose child has died. Since the study includes the development of initial theory and model construction aided by data collection, structural equation modeling (SEM) is utilized as the analysis method. Results found statistically significant effects of attachment style, coping strategy, social support on the level of parental grief. Different groups showed different behavioral patterns in response to the death of a child. Specifically, women showed more insecure attachment style, had more daily spiritual experiences and perceived more social support. Older participants perceived less social support. Implications for social work practice, research, theory development, policy change are discussed

    A systematic review was conducted to explore published quantitative and qualitative research describing patient-reported outcomes of palliative telehealth intervention studies. Multiple databases were searched for articles published between January 2006 and May 2016, which met study criteria. Methodological quality was assessed using Cochrane Collaboration’s tool for assessing risk of bias for quantitative articles. For studies reporting qualitative outcomes, a checklist was used to evaluate trustworthiness of the methodology. Of the 6 studies reporting quantitative outcomes, 3 studies were rated as having moderate study quality, and 3 studies were rated as having low study quality. Of the 6 studies reporting qualitative outcomes, 3 reported 5 different methods for ensuring trustworthiness, whereas 1 article reported 4 methods, 1 reported 3, and 1 article reported 2 methods. Studies were notably diverse in terms of patient population, technology used, outcomes measures, and methodology. Results across studies were also variable. Methodological factors were major limitations. Recruitment problems, participant attrition, and lack of standardized outcomes measures impacted outcome assessment. Overall, research support for positive patient outcomes in palliative telehealth interventions was weak. However, all studies but one found positive results to support the intervention

    “Our Only Child Has Died” – A Study of Bereaved Older Chinese Parents

    Full text link
    Long and complicated grief is a relevant factor contributing to the deterioration of the older adults’ later life quality. In China, the unintentional consequence of the one child policy has emerged. There, the group of older adults who lost their only child is called shiduers. The current study compared 42 older adults who lost their only child to 33 older adults who have a child, in term of their physical and mental health, and social support. The results confirmed the general deteriorating trend in those aspects of the bereaved Chinese parents’ life after their only child’s death. The results also revealed the impairments on the shiduers’ physical, mental, and social aspects were significant, compared to the clinical diagnosis cutoff points used in Western countries. Unique policy and cultural characteristics are the main factors contributing to the severe impairment of shiduers. Results have implications for policy advocacy and practice intervention in specific cultural environments

    A Systematic Review of Telehealth in Palliative Care: Caregiver Outcomes

    Full text link
    Objective: Telehealth interventions have proven efficacy in healthcare, but little is known about the results of such interventions in palliative care. We conducted a systematic review to evaluate caregiver outcomes related to palliative telehealth interventions. Materials and Methods: We searched multiple databases for articles published between January 2003 and January 2015 related to telehealth in palliative care. Two hundred twenty-one articles were considered; nine of these met study inclusion criteria. Data on study design, population, interventions, methods, outcomes, conclusions, and methodological quality were extracted and evaluated by three investigators. Results: Of the nine studies, five measured caregiver quality of life, three measured caregiver anxiety, and two measured caregiver burden. All the studies measuring caregiver quality of life showed no significant difference after telehealth interventions. The caregiver anxiety score decreased after the intervention in two studies, and one study reported significantly reduced caregiver burden. Although feasibility of or caregiver satisfaction with the telehealth intervention was not the focus of this review, most studies reported such findings. Of the nine studies, the majority were rated as having moderate quality using the Cochrane Collaboration’s tool for assessing risk of bias. Conclusions: This systematic review suggests there is evidence of overall satisfaction in caregivers who undergo a telehealth intervention, but outcomes reported were often not substantial. Methodological flaws and small sample sizes negatively affected study quality. More rigorous research to test and evaluate such palliative interventions is needed

    Assessing the Impact of Factors on Parental Grief Among Older Chinese Parents

    Full text link
    A sample of 206 older Chinese bereaved parents was recruited and the effects of attachment style, coping strategy, social support, and spirituality on parental grief were investigated utilizing structural equation modeling. The results revealed problem-focused and dysfunctional coping strategy, insecure attachment style, less social support from family and friends would likely lead to higher levels of parental grief. The study explored how the unique context of Chinese culture and policies may shape the severity and duration of parental grief. It provides a baseline to understand the complexity of parental grief in China and to design and improve future intervention

    An Empirical study on Predicting Blood Pressure using Classification and Regression Trees

    Blood pressure diseases have become one of the major threats to human health. Continuous measurement of bloodpressure has proven to be a prerequisite for effective incident prevention. In contrast with the traditional prediction models with lowmeasurement accuracy or long training time, non-invasive blood pressure measurement is a promising use for continuousmeasurement. Thus in this paper, classification and regression trees (CART) are proposed and applied to tackle the problem. Firstly,according to the characteristics of different information, different CART models are constructed. Secondly, in order to avoid theover-fitting problem of these models, the cross-validation method is used for selecting the optimum parameters so as to achieve thebest generalization of these models. Based on the biological data collected from CM400 monitor, this approach has achieved betterperformance than the common existing models such as linear regression, ridge regression, the support vector machine and neuralnetwork in terms of accuracy rate, root mean square error, deviation rate, Theil IC, and the required training time is also comparativelyless. With increasing data, the accuracy rate of predicting systolic blood pressure and diastolic blood pressure by CART exceeds 90%,and the training time is less than 0.5s

    In recent years, the development of new constellations including Galileo, BeiDou Navigation Satellite System (BDS) and Quasi-Zenith Satellite System (QZSS) have undergone dramatic changes. Since January 2018, about 30 satellites of the new constellations have been launched and most of the new satellites have been included in the precise orbit and clock products provided by the Multi Global Navigation Satellite System (Multi-GNSS) Experiment (MGEX). Meanwhile, critical issues including antenna parameters, yaw-attitude models and solar radiation pressure models have been continuously refined for these new constellations and updated into precise MGEX orbit determination and precise clock estimation solutions. In this context, MGEX products since 2018 are herein assessed by orbit and clock comparisons among individual analysis centers (ACs), satellite laser ranging (SLR) validation and precise point positioning (PPP) solutions. Orbit comparisons showed 3D agreements of 3–5 cm for Galileo, 8–9 cm for BDS-2 inclined geosynchronous orbit (IGSO), 12–18 cm for BDS-2 medium earth orbit (MEO) satellites, 24 cm for BDS-3 MEO and 11–16 cm for QZSS IGSO satellites. SLR validations demonstrated an orbit accuracy of about 3–4 cm for Galileo and BDS-2 MEO, 5–6 cm for BDS-2 IGSO, 4–6 cm for BDS-3 MEO and 5–10 cm for QZSS IGSO satellites. Clock products from different ACs generally had a consistency of 0.1–0.3 ns for Galileo, 0.2–0.5 ns for BDS IGSO/MEO and 0.2–0.4 ns for QZSS satellites. The positioning errors of kinematic PPP in Galileo-only mode were about 17–19 mm in the north, 13–16 mm in the east and 74–81 mm in the up direction, respectively. As for BDS-only PPP, positioning accuracies of about 14, 14 and 49 mm could be achieved in kinematic mode with products from Wuhan University applied
