Trust in older persons: A quantitative analysis of alignment in triads of older persons, informal carers and home care nurses

Abstract Self‐management by older persons could be influenced by the level of trust found in triads of informal carers, formal care providers and care recipient, the older person. Little research has been done on care providers’ trust in older persons. This study aims to explore the level of trust that informal carers and home care nurses have in older persons, the extent of alignment in triads and the relationship between trust in older persons and self‐management. We conducted a cross‐sectional survey study in the Netherlands, sampling 133 older persons, 64 informal carers and 72 nurses, which resulted in 39 triads. Alignment level was analysed through Intraclass Correlation Coefficient 1 scores and absolute and mean difference scores. Correlation analysis and one‐way analysis of variance measured the relationship between trust and self‐management. The results show that triads contain both alignment and misalignment. Misalignment occurs mostly when informal carers and nurses have little trust in the older person while this person views their own behaviour towards their caregivers positively. Care providers’ trust levels relate significantly to their perception of the person's ability to self‐manage, but not to the person's self‐rated ability. This could be explained by care providers not communicating their intrinsic trust in the older person to them. Trust building could be enhanced by organising discussions of mutual expectations of trust and both formal and informal care providers could benefit from compassionate assessment training, to learn how to openly express their trust in the older person.
A retrospective study of an invasive versus conservative strategy in patients aged ≥80 years with acute ST-segment elevation myocardial infarction

Objective To investigate what is the most appropriate strategy for patients with ST-segment elevation myocardial infarction (STEMI) aged ≥80 years in China. Methods This cohort study retrospectively enrolled patients with STEMI aged ≥80 years old and grouped them according to the treatment strategy that was used: a conservative treatment strategy or an invasive treatment strategy. Factors associated with whether to perform an invasive intervention, in-hospital death and a good prognosis were investigated using logistic regression analyses. Results A total of 232 patients were enrolled: conservative treatment group (n = 93) and invasive treatment group (n = 139). Patients in the invasive treatment group had a better prognosis and lower incidence of adverse events compared with the conservative treatment group. Advanced age, creatinine level and a higher Killip class were inversely correlated with whether to perform an invasive intervention, while the use of beta-receptor-blocking agents was a favourable factor for invasive treatment. Hypertension and a higher Killip class were risk factors for in-hospital death, while the use of beta-receptor-blocking agents and diuretics decreased the risk of in-hospital death. Conclusions An invasive treatment strategy was superior to a conservative treatment strategy in patients with STEMI aged ≥80 years.
COX2 is induced in the ovarian epithelium during ovulatory wound repair and promotes cell survival†

Abstract The ovarian surface epithelium (OSE) is a monolayer of cells surrounding the ovary that is ruptured during ovulation. After ovulation, the wound is repaired, however, this process is poorly understood. In epithelial tissues, wound repair is mediated by an epithelial-to-mesenchymal transition (EMT). Transforming Growth Factor Beta-1 (TGFβ1) is a cytokine commonly known to induce an EMT and is present throughout the ovarian microenvironment. We, therefore, hypothesized that TGFβ1 induces an EMT in OSE cells and activates signaling pathways important for wound repair. Treating primary cultures of mouse OSE cells with TGFβ1 induced an EMT mediated by TGFβRI signaling. The transcription factor Snail was the only EMT-associated transcription factor increased by TGFβ1 and, when overexpressed, was shown to increase OSE cell migration. A polymerase chain reaction array of TGFβ signaling targets determined Cyclooxygenase-2 (Cox2) to be most highly induced by TGFβ1. Constitutive Cox2 expression modestly increased migration and robustly enhanced cell survival, under stress conditions similar to those observed during wound repair. The increase in Snail and Cox2 expression with TGFβ1 was reproduced in human OSE cultures, suggesting these responses are conserved between mouse and human. Finally, the induction of Cox2 expression in OSE cells during ovulatory wound repair was shown in vivo, suggesting TGFβ1 increases Cox2 to promote wound repair by enhancing cell survival. These data support that TGFβ1 promotes ovulatory wound repair by induction of an EMT and activation of a COX2-mediated pro-survival pathway. Understanding ovulatory wound repair may give insight into why ovulation is the primary non-hereditary risk factor for ovarian cancer. Summary sentence COX2 increases epithelial cell survival under the stress conditions observed during ovulatory wound repair, therefore promoting survival in cells that might otherwise undergo apoptosis due to the accumulation of DNA damage present at ovulation.
When I relive a positive me: Vivid autobiographical memories facilitate autonoetic brain activation and enhance mood

Autobiographical memory is vital for our well‐being and therefore used in therapeutic interventions. However, not much is known about the (neural) processes by which reliving memories can have beneficial effects. This study investigates what brain activation patterns and memory characteristics facilitate the effectiveness of reliving positive autobiographical memories for mood and sense of self. Particularly, the role of vividness and autonoetic consciousness is studied. Participants (N = 47) with a wide range of trait self‐esteem relived neutral and positive memories while their bold responses, experienced vividness of the memory, mood, and state self‐esteem were recorded. More vivid memories related to better mood and activation in amygdala, hippocampus and insula, indicative of increased awareness of oneself (i.e., prereflective aspect of autonoetic consciousness). Lower vividness was associated with increased activation in the occipital lobe, PCC, and precuneus, indicative of a more distant mode of reliving. While individuals with lower trait self‐esteem increased in state self‐esteem, they showed less deactivation of the lateral occipital cortex during positive memories. In sum, the vividness of the memory seemingly distinguished a more immersed and more distant manner of memory reliving. In particular, when reliving positive memories higher vividness facilitated increased prereflective autonoetic consciousness, which likely is instrumental in boosting mood.
Political Efficacy as a Buffer of the Heightened Risk of Posttraumatic Stress in Disadvantaged Communities.

External collective political efficacy (PE) is an individual's perception of the extent to which the government is responsive to the needs of his or her group or community or to its collective actions. Does PE play a role in the association between exposure to political violence and posttraumatic stress? The current study aimed to examine whether such PE may help explain why exposure to political violence results in posttraumatic stress for some people but not others. Based on the conservation of resource theory, research has found that residents of some types of communities are less likely to suffer from posttraumatic stress when exposed to political violence, due to the economic and psychological resources these communities provide. Political efficacy, as an individual-level factor that relates to the community, may help predict who will suffer more or less posttraumatic stress from exposure to political violence within a given community. Based on a panel study conducted immediately before and after the 2008-2009 Gaza conflict (N = 650) and hierarchical linear modeling analyses, we found that type of community indeed moderated the association between exposure to political violence and posttraumatic stress, Δ-2 log likelihood = 30.4, p < . 001. In addition, we found that PE mitigated the psychological distress resulting from exposure to political conflict in disadvantaged communities, Δ-2 log likelihood = 22.8, p < . 001. This study not only further untangled the association between exposure and distress during times of war but also identified the role that governments can play in preventing conflict-induced distress beyond offering physical protection.
Effects of moxibustion on pain behaviors in patients with rheumatoid arthritis

Abstract Background: Pain is the main symptom of patients with rheumatoid arthritis (RA). Reports of the effects of moxibustion on patients with rheumatoid arthritis have reached various conclusions. The aim of this meta-analysis was to evaluate the effect of moxibustion on pain in patients with RA. Methods: A systematic search of MEDLINE, EMBASE, the Cochrane Library, and the Chinese databases Wan Fang Med Database, CNKI, and VIP (until November, 2018) was used to identify studies reporting pain (on a visual analogue scale (VAS)), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and rheumatoid factor (RF) levels, response rate, and the ACR50 rate in patients with RA. Results were expressed as mean difference (MD) and 95% confidence intervals (CI). Results: Six studies involving 281 participants were included. Moxibustion had significant effects on pain (VAS: MD = −0.53, 95% CI [−0.94, −0.12], P =.01). Moreover, moxibustion had effects on CRP (MD = −2.84, 95% CI [−5.13, −0.55], P =.01), ESR (MD = −8.44, 95% CI ([−13.19, −3.68], P =.0005), and RF (MD = −6.39, 95% CI [−18.57, 5.79], P =.30). Additionally, it had effects on response rate (n = 249, RR = 1.26, 95% CI [1.11, 1.43], P =.0004) and ACR50 rate (n = 140, RR = 1.44, 95% CI [1.11, 1.88], P =.007). Conclusion: We found that moxibustion with Western medicine therapy is superior to Western medicine therapy alone for pain in patients with RA. Moxibustion had significant effects on pain in patients with RA, but the effects of moxibustion on inflammatory factors in RA were unclear.
Determinants of Bone Mass and Insulin Resistance in Korean Postmenopausal Women: Muscle Area, Strength, or Composition?

Purpose Muscle mass, strength, and composition determine muscle quantity and quality. However, data on muscle properties in relation to bone mass or insulin resistance are limited in Asian populations. This study aimed to investigate the relative importance of muscle measurements in regards to their relationship with lower bone mass and insulin resistance. Materials and Methods In this study, 192 postmenopausal women (age, 72.39±6.07 years) were enrolled. We measured muscle cross-sectional area (CSA) and attenuation at the gluteus maximus and quadriceps muscles through quantitative computed tomography. Muscle strength and physical performance were evaluated with the hand grip test and Short Physical Performance Battery (SPPB). Pearson correlation analysis and linear regression were performed to evaluate the relationship between muscle properties and homeostatic model assessment-insulin resistance (HOMA-IR) or bone mineral density (BMD). Results Muscle CSA, hand grip strength, and SPPB score held positive correlations with spine and hip BMDs, but not with insulin resistance. In contrast, muscle attenuation of the gluteus maximus or quadriceps was inversely related to HOMA-IR (r=−0.194, p=0.018 and r=−0.292, p<0.001, respectively), but not BMD. Compared with the control group, muscle CSA was significantly decreased in patients with osteoporosis; however, decreased muscle attenuation, indicating high fat infiltration, was found only in patients with diabetes. Conclusion Muscle mass, strength, and physical performance were associated with low bone mass, and accumulation of intramuscular fat, a histological hallmark of persistently damaged muscles, may play a major role in the development of insulin resistance in Korean postmenopausal women.
Simulation of Fusion Localization Based on a Single WiFi AP and PDR

WiFi Localization and Pedestrian Dead Reckoning(PDR) are attracting increasing attention due to its wide deployment and ubiquity on smartphones respectively. In this paper, we propose a fusion system based on Kalman Filter(KF) algorithm which combines a Single WiFi AP positioning system and PDR. Single WiFi AP positions depends on ToF calculation and AoA calculation which are breakthroughs in recent researches. PDR is variant of dead reckoning system which rely on inertial sensors on mobile phones. The fusion system makes best use of the advantages and bypass the disadvantages. Simulation results demonstrate that the performance of the fusion system outperforms the two independent systems.
Motion Control of Under-actuated Aerial Robotic Manipulators

This thesis presents model-based adaptive motion control algorithms for under-actuated aerial robotic manipulators combining a conventional multi-rotor Unmanned Aerial Vehicle (UAV) and a multi-link serial robotic arm. The resulting control problem is quite challenging due to the complexity of the combined system dynamics, under-actuation, and possible kinematic redundancy. The under-actuation imposes second-order nonholonomic constraints on the system motion and prevents independent control of all system degrees of freedom (DOFs). Desired reference trajectories can only be provided for a selected group of independent DOFs, whereas the references for the remaining DOFs must be determined such that they are consistent with the motion constraints. This restriction prevents the application of common model-based control methods to the problem of this thesis. Using insights from the system under-actuated dynamics, four motion control strategies are proposed which allow for semi-autonomous and fully-autonomous operation. The control algorithm is fully developed and presented for two of these strategies; its development for the other two configurations follows similar steps and hence is omitted from the thesis. The proposed controllers incorporate the combined dynamics of the UAV base and the serial arm, and properly account for the two degrees of under-actuation in the plane of the propellers. The algorithms develop and employ the second-order nonholonomic constraints to numerically determine motion references for the dependent DOFs which are consistent iv with the motion constraints. This is a unique feature of the motion control algorithms in this thesis which sets them apart from all other prior work in the literature of UAVmanipulators. The control developments follow the so-called method of virtual decomposition, which by employing a Newtonian formulation of the UAV-Manipulator dynamics, sidesteps the complexities associated with the derivation and parametrization of a lumped Lagrangian dynamics model. The algorithms are guaranteed to produce feasible control commands as the constraints associated with the under-actuation are explicitly considered in the control calculations. A method is proposed to handle possible kinematic redundancy in the presence of second-order motion constraints. The control design is also extended to include the propeller dynamics, for cases that such dynamics may significantly impact the system response. A Lyapunov analysis demonstrates the stability of the overall system and the convergence of the motion tracking errors. Experimental results with an octo-copter integrated with a 3 DOF robotic manipulator show the effectiveness of the proposed control strategies.
A Survey of Indoor Localization Techniques for Smartphones

Pervasive and ubiquity computing are expected to expand the development of new business oriented mobile applications. Knowing the exact physical location of the wireless devices is crucial for providing awareness of these applications. Many algorithms have been proposed for wireless localization, but most of them are designed for outdoor localization by using Global Positioning System (GPS) signals. In indoor environments, the GPS is not available, which makes localizations not trivial. This paper surveys state-of-the-art attempts toward efficient indoor localization for smartphones. We define a taxonomy used for better classification of the algorithms. Furthermore, we describe the characteristics of modern indoor positioning systems, as well as the challenges associated with the localization techniques. Finally, we provide real experiments using different smartphone models in order to discover typical problems that occur when signal strength is used as a range measurement technique in indoor localization systems.
Twin control moment gyros for small satellites.

Future spacecraft will, of necessity, require rapid rotational manouvreability or agility. Such rapid retargeting manoeuvres are often subject to the physical limits of actuators. Control Moment Gyros (CMGs) are employed as primary actuators because of their high torque control capability. A typical configuration used is the 4 Single-Gimbal Control Moment (4SGCMG) pyramid mounting arrangement [48]. In the 1960s researchers studied an arrangement of CMGs called Twin Control Moment Gyros (TCMGs) [6, 11,20]. At the time these configurations were considered unsuitable for large satellite platforms, and the 4SGCMG pyramid configuration became the most common arrangement. The research in this report revisits their work, to address the suitability of TCMGs to future small satellite missions. Candidate configurations of both SGCMG and TCMG arrangements are considered as possible replacements for the 4SGCMG pyramid configuration. The candidate configurations are compared m terms of torque capability, power consumed and mass and volume occupied. In this report the principles of Single-Control Moment Gyro and Twin-Control Moment Gyro operation are studied. The study of Euler's equations and controller principles lead to the implementation of an attitude control system in SIMULINK, for which results are compared with previous work [46]. The results of a sizing/selection process show that the 4SGCMG pyramid configuration performs the best all round in terms of torque developed, power consumed and mass and volume occupied. Of the candidate configurations the 6SGCMG pyramid configuration stands out as a possible replacement for the baseline configuration. Of the TCMG configurations the 3TCMG pyramid configuration is the most promising. It is recommended that the 3TCMG pyramid configuration is investigated further. If the total mass of this system could be reduced it could be a contender as a possible replacement for the 4SGCMG pyramid configuration.
Engfi Gate: An Indoor Guidance System using Marker-based Cyber-Physical Augmented-Reality

A guidance system is needed when freshmen explore their new building environment. With the advancements of mobile technologies, a guidance system using mobile computing devices such as mobile phones or tablets could aid freshmen in locating the desired destination with ease. The proposed system consists of three main subsystems: the marker-based cyber-physical interaction (CPI) system, the indoor positioning (IP) system, and the augmented-reality (AR) system. With the help of visible markers and invisible markers, the CPI system allows the users to do interactions between the physical and cyber environments; the IP system produces accurate user position information; the AR system provides the users with good user experiences. An Android application, named Engfi Gate, is developed to realize the system design in the test environment. This paper also shows the comparisons of the proposed system with other related systems. Furthermore, the design architecture of Engfi Gate system can be used in other location-based applications.
Status and distribution of breeding cattle egret and little egret in Amroha using density method

We report the status and distribution of nesting egrets in Amroha using a density method, which is robust, cost-effective and useful in all field situations. We estimated a mean of 0.016 nests/m 3 of canopy volume ± 0.008 95% CI for cattle egrets and 0.024 nests/m 3 of canopy volume ± 0.01 95% CI for little egrets. Colony size averaged 171 nests ± 89 95% CI. We report a human -induced hatching failure of 1782 and 1613 eggs of cattle egrets and little egrets respectively, and poaching of 1274 nestlings of egrets (cattle egret = 688; little egret = 586). Correlation analysis indicated that occasional disturbance/threat does not impact nest densities, but intense and constant ones may even result in desertion of colonies. ONE of the major priorities in conserving animals is monitoring changes in their populations to find prescriptions for their long-term survival 1–4 . One of the most simple and commonly used methods for recording and monitoring ardeids is counting their nests or enumerating the t otal in the roosts 5,6
Implementation and Analysis of a Refactoring Tool for Detecting Code Smells

: Software development is a field which is in action for decades. Preparing code for Software is not a difficult task, but preparing an efficient code is complicated one. To change the code is to make internal structure of the code easier to understand and economic to modify, without changing the behavior and desired response. More changes will make software patchy. No Software is free from smells especially the patchy one. Lots of work has been done for detecting and removing a few of the smells (Refactoring) from code. In this paper our main focus will be on tool SCSD (Software Code Smell Detector) developed, uses a bit classification, clustering approach with K-mean Clustering Algorithm to detect the code smells, which can implement completely different architecture if it discovers smell.
Expanded survival analysis

Proportional hazards regression was used in this study to demonstrate an association between SCFA concentrations in feces and the longevity of mice. Given the limited number of samples for which matched chemical and survival data are available, statistical testing of associations with SCFAs were carried out in the pooled dataset. Therefore, to account for known effects of treatment, sex, and site, the primary null model used in this study includes terms for all main, two, and three-way interactions of the design covariates: treatment, sex, and study site. A priori, a number of these terms were expected to be non-zero, based on ITP findings from previous cohort years [1, 2]. Indeed, when survival data from all of control and ACA treated mice in this cohort were analyzed together, effects were detected that recapitulated these expectations, including: increased longevity of females, increased longevity with ACA treatment, and increased longevity of control males at UM (see Tbl. 1).
Statistical Analysis of Long Term Temporal Trends of Precipitation and Temperature in Wainganga Sub-Basin , India

Present study explores changes in precipitation, and mean, maximum & minimum temperatures of seven stations located in the Wainganga sub-basin, Central India. Annual trends were analyzed using Mann-Kendall test and Sen's slope estimator test for two time periods 1901-2002, and 1971-2002 to study recent changes in last 30 years. All stations are exhibited increasing trends in mean, maximum, minimum temperatures and potential evapotranspiration; decreasing trends are found in precipitation and wet day’s frequency during both the periods. Comparison of trends during these periods depicts that the trends have become strong during the last 30 years except maximum temperature.
