PurposeThis study investigated the impact of age and myopia on visual form perception among Chinese school-age children.MethodsThis cross-sectional study included 1,074 students with a mean age of 12.1 ± 4.7 years. The mean spherical equivalence refraction of the participants was −1.45 ± 2.07 D. All participants underwent distance visual acuity, refraction measurement and local and global visual form perception test including orientation, parallelism, collinearity, holes and color discrimination tasks.ResultsThe reaction times of emmetropes were slower than those of myopic and high (...) myopic groups on both local and global discrimination tasks. A reduction in reaction times was found with increasing age on both local and global discrimination tasks. Age was significantly associated with both local and global visual perception performance after adjusting for gender, visual acuity and SER.ConclusionsThis study revealed that both local and global visual perception improve with age among Chinese children and that myopes seem to have better visual perception than emmetropes.

Critical types of infrastructure are provided by the state to maintain the people’s livelihood, ensure economic development, and systematic government operations. Given the development of ever more complicated critical infrastructure systems, increasing importance is being attached to the protection of the components of this infrastructure to reduce the risk of failure. Power facilities are one of the most important kinds of critical infrastructure. Developing an effective risk detection system to identify potential failure modes of power supply equipment is crucial. This (...) study seeks to improve upon prior approaches for risk assessment by proposing a hybrid risk-assessment model using the concepts of failure mode and effect analysis and multiple-criteria decision-making. The proposed model includes a cost-based factor for decision-makers. The subjectivity and uncertainty in FM assessment are adjusted through the rough number method. The original risk priority number can be expanded by including the entropy weights in the risk index. Furthermore, to rank the risk priorities in a rational manner, a modified technique for order preference by similarity to ideal solution is adopted. The applicability and effectiveness of the proposed method were demonstrated by considering an example of a turbine steam engine in a nuclear power plant. (shrink)

This paper investigates a composite learning prescribed performance control scheme for uncertain strict-feedback system. Firstly, a prescribed performance boundary condition is developed for the tracking error, and the original system is transformed into an equivalent one by using a transformation function. In order to ensure that the tracking error satisfies the PPB, a sufficient condition is given. Then, a control scheme of PPC combined with neural network and backstepping technique is proposed. However, the unknown functions cannot be guaranteed to estimate (...) accurately by this method. To solve this problem, predictive errors are defined by applying online recorded date and instantaneous date. Furthermore, novel composite learning laws are proposed to update NN weights based on a partial persistent excitation condition. Subsequently, the stability of the closed-loop system is guaranteed and all signals are kept bounded by using composite learning PPC method. Finally, simulation results verify the effectiveness of the proposed methods. (shrink)

ObjectiveThe objective of the study was to explore the relationship between social support and fatigue as well as the mediating role of social functioning on that relationship.BackgroundPsychosocial factors such as social support and social functioning may influence patients’ fatigue symptoms. There is limited evidence on the relationship between social support, social functioning, and fatigue in liver transplant recipients.MethodsA total of 210 patients with liver transplants from two tertiary hospitals were enrolled in the current study. Questionnaires used include one for general (...) demographic data, the Perceived Social Support Scale, Social Disability Screening Schedule, and Fatigue Symptom Inventory.ResultsA total of 126 recipients reported fatigue. Gender, residence, BMI, and liver function were the primary factors affecting fatigue. Social support was positively correlated with social functioning and was negatively correlated with fatigue. The effect of social support on fatigue was partially mediated by social functioning.ConclusionThe fatigue of liver transplant recipients should be attended to. The higher the social support, the lower the fatigue of liver transplant recipients. Social support may also reduce fatigue through social functioning. The liver transplant team should help the liver transplant recipient establish a social support system, restore social functioning, and reduce fatigue symptoms. (shrink)

The latest book is a timely application of the Pragma-Dialectical argumentative approach to medical consultation. The book consists of six chapters, which are concerned with topics pertaining to resolving differences of the opinion in doctor-patient interaction. With the publication of the book, the authors have made new contributions to the field of doctor-patient argumentative discourse.

This paper aims at investigating the dynamic characteristics of a microring driven by dual arch electrodes because they are basic elements of microelectrostatic motors. The dual arch electrodes surround the periphery of the microring and are arranged symmetrically to the center of the ring. The electrodes are fixed while the microring is flexible. The electrostatic force will deform the microring, while the deflection of the microring changes the gap between the microring and the electrodes, thereby changing the electrostatic force. Therefore, (...) this is an electromechanical coupling effect. The nonlinear partial-differential equation that governs the motion of the microring is derived based on thin shell theory. Then, based on the assumption of small deflection, the nonlinear governing equation is linearized by truncating the higher-order terms of the Taylor series expansion of the nonlinear electrostatic force. After that, the linearized governing equation is discretized into a set of ordinary differential equations using Galerkin method in which the mode shape functions of the ring are adopted. The influences of the structural damping of the microring and the span of the arch electrodes on the forced response and dynamical stabilities of the microring are investigated. The results show that the damping ratio has a great influence on the system instability during high-frequency excitation. The unstable region of the system can increase with the increase of the electrode span; the response amplitude can also be increased within a certain range. (shrink)

Both developing and developed countries face an increasing mismatch between what patients expect to receive from healthcare and what the public healthcare systems can afford to provide. Where there has been a growing recognition of the entitlement to receive healthcare, the frustrated expectations with regards to the level of provision has led to lawsuits challenging the denial of funding for health treatments by public health systems. This book analyses the impact of courts and litigation on the way health systems set (...) priorities and make rationing decisions. In particular, it focuses on how the judicial protection of the right to healthcare can impact the institutionalization, functioning and centrality of Health Technology Assessment (HTA) for decisions about the funding of treatment. Based on the case study of three jurisdictions - Brazil, Colombia, and England - it shows that courts can be a key driver for the institutionalization of HTA. These case studies show the paradoxes of judicial control, which can promote accountability and impair it, demand administrative competence and undermine bureaucratic capacities. The case studies offer a nuanced and evidence-informed understanding of these paradoxes in the context of health care by showing how the judicial control of priority-setting decisions in health care can be used to require and control an explicit scheme for health technology assessment, but can also limit and circumvent it.

The importance of data literacy and the need of raising and improving it through formal educational channel or public engagement has repeatedly been flagged up in each of the past Economic and Social Research Council-funded Data-Psst! Seminar I attended in 2014–2016. There is a real demand for action taking. I took advantage of the knowledge I learned from the Data-Psst seminars and devised a module teaching Level 5 undergraduate media students about critical issues in today’s data-centric digital society, including privacy (...) and surveillance. In this article, I share how the class activities were devised and carried out, and how guided engagement with the current debate in privacy and surveillance were realised. I also draw on relevant pedagogical theories to discuss my educational approaches, student performance, the challenges of the project, and evaluate and reflect upon the outcomes. This report from the field provides fresh first-hand information about the data ethics of the younger public who are practising media arts and their behaviours and attitudes towards privacy and surveillance. This article shall open up the discussion about the role educators play in enriching public engagement with critical thinking about Big Data. The lessons learned can also contextualise the pedagogical implication of the recent scholarly research on Big Data and privacy, and provide a framework for constructing future collaborative or creative projects.

Liver transplantation (LT) activities during the COVID-19 pandemic have been curtailed in many countries. The impact of various policies restricting LT on outcomes of potential LT candidates is unclear. We studied all patients on the nationwide LT waitlists in Hong Kong and Singapore between January 2016 and May 2020. We used continuous time Markov chains to model the effects of different scenarios and varying durations of disruption on LT candidates.

In this study, we examined the effects of parental phubbing on learning burnout in elementary and secondary school students and its mechanism of action. A questionnaire method was applied to investigate parental phubbing, parent–child attachment, ego depletion, and learning burnout among 2090 elementary and secondary school students in Anhui Province, China. The results are as follows: Parental phubbing was significantly correlated with parent–child attachment, ego depletion, and learning burnout; Parental phubbing has an indirect impact on learning burnout in elementary and (...) secondary school students through three pathways: a separate mediating effect on parent–child attachment, a separate mediating effect on ego depletion, and a chain mediating effect on both. Parental phubbing is a risk factor for Learning Burnout, which can positively affect Learning Burnout in elementary and secondary school students. The findings of the study contribute to revealing the influence mechanism of parental phubbing on learning burnout in elementary and secondary school students. (shrink)

One task of historians is to construct causal ascription of singular historicals between eminent historical events. For instance, the controversy resulting from the confusing butterfly ballot of Florida’s year 2000 presidential election cost Gore his presidency. However, to research into these matters is inevitably to appeal to counterfactual deliberation in an epistemic fashion because the past is fixed. One standard idea is Max Weber’s, Weber causation: “f was a cause of φ” is assertable iff “¬f □→ ¬φ” is assertable. Reiss (...) gives an exceptionally good analysis of this topic and outlines historians’ reasoning, claiming that backtracking analyses of counterfactual conditionals employed in historical thought experiments is the signature of historical study of causal ascription of singular historicals. Nevertheless, he concludes that it is very difficult to reach an uncontroversial ascription for this sort in most cases. For this reason, he proposes to find difference-making relations that will suffice. The objective of this paper is to provide a more fine-grained, intervention-based, backtracking analysis of counterfactual conditionals upon which a more satisfactory account of causal ascription of singular historicals can be given. Reiss’ account of difference-making relation will be shown to be unsatisfactory. Moreover, a formal ground of the epistemology of historical thought experiments can be given, along with the constraints of this account resultant from the semantic features of non-transitivity and strong centering of counterfactual conditionals. Finally, some epistemological points of causal ascription of singular historicals and historical thought experiments will be given. (shrink)

The existing differential item functioning detection approaches relying on item difficulty or item discrimination are limited for understanding the associates of DIF items, and consequently, DIF items were conventionally either deleted or ignored. Given the importance of minimizing DIF items in test construction, teachers or testing practitioners need more information regarding possible associates of DIF items. Using an example of a teacher-made mathematics achievement test, this study aimed to examine how the Poly-BW indices contributed to the properties of gender-related DIF (...) items. Data from a 34-item mathematics achievement test that involved 1,439 seventh-grade students from Taiwan showed that the differences of the defenselessness and power indices between men and women served as salient predictors of the DIF measures estimated by the Poly Simultaneous Item Bias Test procedure and with satisfactory accuracy of hit rates. Items with relatively large defenselessness for men were likely to present male-favoring DIFs, whereas items with relatively large power for men were likely to present female-favoring DIFs. The Poly-BW indices yielded directions for modifying items for teachers in practice. (shrink)

BackgroundSolution-focused model is an intervention method that fully mobilizes patients’ initiative through their potential. We aimed to investigate the effects of SFM on anxiety and postpartum depression in nulliparous pregnant women compared with routine care services.MethodsWe chose the mothers diagnosed as depressed or with depressive tendency by Edinburgh Postpartum Depression Scale at 28 weeks of gestation and divided them into the intervention and control groups. The control group only took the routine pregnancy healthy nursing, while the SFM group took the (...) regular nursing and SFM counselling. Different assessments were conducted at 28 weeks of gestation, post-delivery, and post-intervention to evaluate the anxiety and depression levels of the patients. Finally, nursing satisfaction was evaluated by the nursing satisfaction questionnaire.ResultsCompared with the control group, SFM could decrease the scores of anxiety and depression more effectively and influence sleep quality more positively. We also found that SFM resulted in significantly higher nursing satisfaction than that in the control group.ConclusionIn conclusion, SFM could effectively alleviate anxiety and PPD in nulliparous pregnant women.

We report that upon excitation by a single pulse, a classical harmonic oscillator immersed in the classical electromagnetic zero-point radiation exhibits a discrete harmonic spectrum in agreement with that of its quantum counterpart. This result is interesting in view of the fact that the vacuum field is needed in the classical calculation to obtain the agreement.

This book focuses on the connection between action and verbal communication, exploring topics such as the mechanisms of language processing, action processing, voluntary and involuntary actions, knowledge of language and assertion. Communication modelling and aspects of communicative actions are considered, along with cognitive requirements for nonverbal and verbal communicative action. Contributions from expert authors are organised into three parts in this book, focussing on language in communication, action and bodily awareness, and sensorimotor interaction and language acquisition. Readers will discover various (...) methods that have been employed in investigations presented here, including neurological experiment, computational modeling, and logical and philosophical analysis. These diverse expert perspectives shed light on the extent to which a mechanism for processing actions also facilitates the processing of language, and the authors' work prompts further interdisciplinary investigation of the relationship between language and action. This book is written for readers from different academic backgrounds; from graduate students to established academics in disciplines ranging from neuroscience to psychology, philosophy, linguistics and beyond. Earlier versions of the selected essays in this book were presented at the 2013 IEAS Conference on Language and Action, held in Taipei, Taiwan. (shrink)

Off-seat behaviour refers to students leaving their seats and walking out of a classroom without the teacher noticing. This behaviour occurs in special education for students with certain special needs, which would lead to serious safety problems. This study carried out an inattentional blindness test to explore whether the location of seats in classrooms would impact teachers’ detection rate regarding off-seat behaviours. The participants were 126 pre-service teachers (Mage= 18.72 ± 0.723; 92% female) who were invited to perform the primary (...) task of counting students raising their hands up whilst the disappearance of one of the students was introduced as an unexpected occurrence. The results show that peripheral seats were more detectable than the central ones for the teachers to notice the “missing student.” Meanwhile, the left and below oriented seats were more likely to be ignored compared to those that were right and upper oriented. These results suggest the existence of a location effect in the classroom that is associated with teachers’ attention regarding off-seat behaviour. This study has implications for classroom management in terms of arranging students’ seats appropriately to assist in increasing teachers’ identification of this hazard. (shrink)

This study investigated how Paul’s Jewish background, including some elements of pre-rabbinical Jewish literature, influenced the letter to the Galatians with regard to the concept of adoption (υἱοθεσία) (Gl 4:1–7). As Paul was writing to a Gentile audience, wanting to persuade them to return to the true gospel, metaphors of adoption, embedded in the understanding of the Graeco-Roman household, became effective communication bridges to reach his audience. Within this framework, Israel’s God was depicted as the caring father of the household, (...) who through his son Jesus Christ redeems all human beings from the status of slaves to that of children with full rights of inheritance. Contribution: God’s redemption is not merely a forensic sense of justification but also the imagery of relationship in the household by which God does not merely set one free from sin by securing us through Jesus Christ into the society of the righteous, but also adopts us into his family.
