GraphicalPatients with early- to middle-stage PD were enrolled for C-Gait assessment and traditional walking ability assessments. The correlation of C-Gait assessment and traditional walking tests were studied. Two models were established based on C-Gait assessment and traditional walking tests to explore the value of C-Gait assessment in predicting freezing of gait.ObjectiveEfficient methods for assessing walking adaptability in individuals with Parkinson’s disease are urgently needed. Therefore, this study aimed to assess C-Gait for detecting freezing of gait in patients with early- to (...) middle-stage PD.MethodPeople with PD diagnosis were recruited from April 2019 to November 2019 in Beijing Rehabilitation Hospital. The participants performed six items of walking adaptability on an instrumented treadmill augmented with visual targets and obstacles. The patient’s walking adaptability was evaluated by C-Gait assessment and traditional walking tests, and FOG-related indexes were collected as outcome measures. Two discriminant models were established by stepwise discriminant analysis; area under the receiver operating characteristic curve was used to validate the models.ResultIn total, 53 patients were included in this study. Most C-Gait assessment items had no or low correlations with traditional walking tests. The obstacle avoidance and speed of adaptation items could lead to FOG with high sensitivity. In addition, the C-Gait assessment model had slightly better discrimination of freezers from non-freezers compared with traditional walking test models ; specifically, obstacle avoidance and speed of adaptation have uniquely discriminant potential.ConclusionC-gait assessment could provide additional value to the traditional walking tests for PD. Gait adaptability assessment, as measured by C-Gait, may be able to help identify freezers in a PD population. (shrink)

Overqualified employees are prevalent in today’s organizations. While previous research suggests that supervisors may not often appreciate employee overqualification, how they may respond to the overqualification of their subordinates unethically has unfortunately been overlooked in organizational research. Drawing on social rank theory, we propose that supervisors may perceive a threat to their status from their overqualified subordinates, leading to supervisor undermining as an unethical response. We further hypothesize that the interpersonal personality traits of subordinates—extroversion and agreeableness—moderate the indirect relationship. We (...) conducted a multi-wave, multisource survey study among supervisor-subordinate dyads (Study 1) and two vignette-based experiments (Studies 2A and 2B) to test our hypotheses. In Study 1, our results show that the positive indirect effect of subordinate overqualification on supervisor undermining through supervisor perceived status threat is weaker when subordinates exhibit low (vs. high) extraversion. Studies 2A and 2B largely replicate the above findings with strengthening the internal validity of our theorization. The implications of our findings for theory and practice are discussed. (shrink)

The book consists of 6 chapters. Chapter One explains the reason why SLA researchers should study the language learning environment in space: population movements associated with internal and external migration and social mobility such as the circuits of commodity production and distribution create much space, in which language learning environment become diverse and uneven. With the spatial perspective, we can fully understand the interactions between language learners and the world or environments.In Chapter Two, by introducing the brief history of Critical (...) Spatial Theory, the author wants to tell us one of the key ideas in the theory: the social production of space, which views space as the product of the social relations of its era. Based on it, the author adds that the production of languages is an integral aspect of the production of space on a global scale. It can help us to understand how social mobility shapes language learning environments. From this perspective, the local environments in which languages are learned are outcomes of the production of space under the influence of mobility. It reiterates the key view that the global mobilities of physical objects (people, goods and information) produce space.In Chapter Three, the author introduces the mainstream views held by modern linguistics: languages are conceptualized as objects in the space. They hold that the spatiality of language is given by providing correct writing systems and standardized rules for various languages. Influenced by mainstream conception of language from modern linguistics, SLA tends to regard languages as self-contained objects in space. However, this view neglects the relation between language and the learning environments. The author holds that the distribution and circulation of languages and their varieties in geographical space produce the spatiality of language, which clears the ground for an environment or object-as-space view of language in Chapter Four.In Chapter Four, the author develops an alternative "objects-as-space" view and introduces three concepts to illustrate spatiality of language: flat ontology, assemblage and mobilities. The concept of flat ontology helps explain what language is and how it comes into being in the world; From assemblage perspective, the author develops the idea that everything is an object, so are human beings and languages. Language (the non-physical object) interacts with various physical objects, forming the language-bearing assemblage. This assemblage is the form of spatiality of language. The mobilities theory explains how language-bearing assemblages develop or change on a global scale because of social mobility, emphasizing the importance of learning environment in SLA. All in all, the author outlines how language makes its way into physical space in the form of assemblages, or assemblages of assemblages.Chapter Five centers on language learning environment. First, the author explains the relation between language learners and their learning environment from an ecological view: the learner is a part of the language learning environment, and second language learning is a spatial interaction between the learners and the semiotic resources provided by environment. Then, the author discusses language environment from two different perspectives. From an 'individual' perspective, environments are assembled by individuals from the spatial resources available; from an 'areal' view, environments are shaped both by local circumstances and global circulations of language-bearing assemblages. Meanwhile, the author also discusses other language environments like the multilingual city and online resources. What the author hopes to develop in this chapter is an environment perspective that grounds the contexts of language learning in space, which helps the readers think about language learning from a spatial perspective.Chapter Six contains three parts. In the first part, it outlines the work of a number of researchers from sociolinguistics and the contribution they made to the spatial theory. In the second part, the author wants to tell us how the idea of language learning environment emerges from his own research. The last part discusses the four main researching routes (areal studies, studies of individuals learning in settings, studies of the construction of individual learning environment and design-based studies) that might influence SLA research on language learning environments and some research methods. The book is in alignment with several recent "turns" occurring in the field of SLA, such as "social turn" (Block, 2003) and "multilingual turn" (May, 2014), both of which bring to the fore the social aspects involved in language learning. While the first "turn" accentuates the role of social context in shaping and influencing learner cognition, the latter highlights how the physical multilingual world remold language learning experiences, and how the mental multilingual world helps raise learners' language awareness, and facilitates their successful construction of an identity of legitimate multi-language users. The book under review joins up the two "turns" in acknowledging that language learners are persons-in-context with organic interaction with social learning environment (Ushioda, 2021). This view has research and pedagogical implications. From the point of doing research, spatial perspectives, advocated in the book, afford huge research potentials for both language teachers and (instructed) SLA researchers to conduct situated investigations, exploring the complex and dynamic nexus between language learners and their surrounding environment (not restricted to people) that play a part in their learning experience, and thus gaining insightful understanding of how individuals and learning contexts are coupled with each other, how they evolve together, and how they constitute an ecosystem that generates affordances, facilitating or constraining language learning. Pedagogically speaking, the spatial perspectives encourage language teachers to hold an ecological view of language teaching and learning, directing their attention to the individuality of each language learner and their complex, dynamic and multifaceted relationality with other learners and the physical realities, rather than solely focusing on the abstract systems (e.g., the development of cognitive aspect). This holistic view allows language teachers to take measures to address concrete questions emerging in and out of the classrooms, and stimulates them to design and experiment with pedagogical interventions that help to create a favorable environment for language learning. This view also invites language teachers to take learner agency into account (Xu & Long, 2020) and to design pedagogical activities that enable learners to take agentive actions to adapt their environments as they actively create and seek their own language learning opportunities, making the world their own (Bronfenbrenner, 1979). In turn, teachers' agency-enabling activities will ultimately help learners to autonomously access a range of resources in this new affordance-rich era to improve their language skills, and thus become more independent in their pathway to life-long learning.Beside the above benefits, the book is also theoretically and methodologically friendly. In illustrating the role of space in SLA, the author invokes a plethora of theories from such disciplines as sociology, sociolinguistics, psychology, etc. This orientation helps readers to build a transdisciplinary framework to capture the multi-layered nature of SLA, and to acquire a nuanced understanding of how language learning is influenced by multiple scales of environmental factors. Methodologically, the author proposes several specific methods that are especially apt to investigate language learning environment. These methods, together with the theoretical foundation laid by the book, will definitely help researchers and language teaching practitioners to further delve into the complex interplay between context and language learners.Admittedly, the book is not without weaknesses. It spends most of its words on illustrating the importance of physical environment in SLA. Another essential component, the virtual environment is insufficiently referenced and discussed. This lacking is undoubtedly a regret the book leaves with us, especially in these years of pandemic, where language learning in virtual spaces is becoming a norm.All in all, the book is an invaluable contribution to the field of SLA, and is worthy of recommending to language teaching practitioners, researchers, and postgraduates in applied linguistics.

Differential tractography and correlation tractography are new tractography modalities to study neuronal changes in brain diseases, but their performances in detecting neuronal injuries are yet to be investigated in patients with mild traumatic brain injury. Here we investigated the white matter injury in mTBI patients using differential and correlation tractography. The diffusion MRI was acquired at 33 mTBI patients and 31 health controls. 7 of the mTBI patients had one-year follow-up scans, and differential tractography was used to evaluate injured fiber (...) bundles on these 7 patients. All subjects were evaluated using digital symbol substitution test and trail making test A, and the correlation tractography was performed to explore the exact pathways related to the cognitive performance. Our results showed that differential tractography revealed neuronal changes in the corpus callosum in all 7 follow-up mTBI patients with FDR between 0.007 and 0.17. Further, the correlation tractography showed that the splenium of the corpus callosum, combined with the right superior longitudinal fasciculus and right cingulum, were correlated with DSST in the acute mTBI patients. The cognitive impairment findings in the acute stage and the longitudinal findings in the corpus callosum in the chronic stage of mTBI patients suggest that differential tractography and correlation tractography are valuable tools in the diagnostic and prognostic evaluation of neuronal injuries in mTBI patients.

The present study aims to survey Chinese mental health professionals’ attitudes toward therapeutic confidentiality with adolescent patients in specific clinical situations, and compare Chinese adolescents’ and parents’ beliefs about when most mental health professionals would breach confidentiality. A sample of 36 mental health practitioners, 152 parents, and 164 adolescents completed a survey to assess their opinions about when confidentiality should be breached in 18 specific clinical situations. Nearly half of the parents and adolescents and 78% of the therapists in our (...) sample selected “yes” in response to the question of whether the principle of confidentiality applies to adolescents. However, 49% of parents indicated “no,” and 53% of adolescents indicated “not sure.” Compared to adolescents, parents were significantly more likely to believe that therapists would breach confidentiality for the high-breach-likelihood items. For the low-breach-likelihood items, adolescents and parents were significantly more likely than therapists to believe confidentiality should be breached. Results from this study provide data to inform the development, refinement, practical implementation, and communication of guidelines and recommendations specific to adolescents receiving psychotherapy in China.

ObjectivesWuhan is the city where coronavirus disease was first reported and developed into a pandemic. However, the impact of the prolonged COVID-19 pandemic on medical staff burnout remains limited. We aimed to identify the prevalence and major determinants of burnout among medical staff 1 year after the beginning of the COVID-19 pandemic in Wuhan, China.Materials and MethodsA total of 1,602 medical staff from three hospitals in Wuhan, China, were included from November 1–28, 2021. Chi-square tests were conducted to compare the (...) prevalence of burnout across groups based on sociodemographic and professional characteristics. A multivariate analysis was performed using a forward stepwise logistic regression model.ResultsApproximately 37.39% of the medical staff experienced burnout 1 year after COVID-19 pandemic. Emotional exhaustion was the most common symptom of burnout, with 1,422 participants reporting a severe EE. Burnout was associated with insufficient social support and “neutral” or “dissatisfied” patient-physician relationships. Respondents who participated in the care of COVID-19 patients had a higher risk of burnout symptoms than those who did not participate. In particular, mental resilience was negatively associated with burnout among the medical staff.ConclusionNearly two-fifths of the participants had symptoms of burnout, with reduced personal accomplishment being the predominant symptom 1 year after COVID-19. Healthcare organizations should regularly measure and monitor burnout among the medical staff. In addition, creating positive work environments and improving the mental resilience of medical staff may be effective ways to reduce burnout. (shrink)

PurposeThis study aimed to explore current developments and trends in the field of subjective well-being of older adults at a macro level and identify research hotspots.MethodsWe included reviews and articles on the SWB of older adults in the Web of Science Core Collection published from 2002 to 2021. We used CiteSpace to draw a knowledge map of the authors, institutions, countries, references, and keywords for visual analysis and used Microsoft Excel tables to count basic information details.ResultsA total of 354 papers (...) were included, and the number of papers published over the past two decades showed a pattern of growth. The core force of publications was primarily attributed to studies conducted in Europe, North America, Asia, and Oceania, which have relatively major issues of aging and good economic strength. However, links between states, institutions, and authors were relatively weak. Cluster analysis showed that the research field could be divided into eight topics: the application of social psychology in the study of the SWB of older adults, aging in older adults, health condition of older adults, achieving successful aging, interventions for SWB, age differences in SWB research, an economic perspective of SWB research and social support for older adults. Current research frontiers are socioeconomic status, community, intervention, participation, adjustment, validation, and personality.ConclusionThe results of the present study provided a comprehensive picture in the research field of SWB of older adults. It showed that the mechanism, especially the bidirectional effect, between the SWB of older adults and its influencing factors is still worthy of further exploration. More research on evidence-based and intervention strategies should be conducted in the future. (shrink)

The teacher self is a composite psychological construct which encompasses the cognitive, affective, emotional, and social dimensions of teaching. This qualitative study draws on Bakhtin’s concepts of dialogism, answerability, and addressivity to discuss how English language teachers negotiated the shifting and conflictive context to construct selves in relation to the promoted communicative language teaching approach. Based on narrative interviews and classroom observations with five tertiary English teachers in China, we found that these teachers were actively engaged in the dialog with (...) their prior learning experiences and active, responsive in answering their contexts while authoring selves in everyday teaching practice. The multiple-case study data support a Bakhtinian understanding that teachers are active users and producers of theory in their own right, highlighting teachers’ agency, creativity, and autonomy. Based on Bakhtin’s dialogism and the case study findings, we bring cognition, identity and practice together and conceptualize the teacher self as having multiple facets and layers: the autobiographical self, the discursive self, and the pedagogical self. The three selves are constitutive of the consummated whole of the teacher self instead of being separate entities functioning individually. The study is concluded with implications for language teacher education and teacher development. (shrink)

This study inspected the effect of Massive Open Online Course and flipped instruction on EFL learners’ foreign language speaking anxiety, foreign language learning motivation, and attitude toward English learning. To fulfill this objective, the Oxford Quick Placement Test was given to 160 Iranian EFL learners, of whom 120 upper-intermediate participants were chosen and divided into two experimental groups—MOOC and flipped —and one control group. After that, all selected participants were administered a speaking anxiety questionnaire and a motivation questionnaire as the (...) pre-test of the research. Then, one of the experimental groups received an online-based instruction via Skype: one conversation was instructed to this group online every session. The other experimental group received the treatment via flipped-based instruction. The audio files and the texts of the conversations were sent to this group via the WhatsApp application because they all had easy access to it. On the other hand, the control group did not receive any Internet-delivered treatment yet was trained through a face-to-face method. This process continued until the last session, and after the treatment period, the post-tests of speaking anxiety and motivation were given to all three groups to determine the effectiveness of the treatment. Moreover, two attitude questionnaires were administered to the experimental groups to examine their attitudes toward the MOOC and the flipped models of instructions. The findings of the One-way ANOVA test, Post-hoc Scheffe test, and paired samples t-test showed that there were significant differences between the post-test of the experimental groups and the control group. The results indicated that the experimental groups significantly outflanked the control group after the treatment. Lastly, the outcomes showed that participants in both experimental groups had positive attitudes toward technological-based instructional environments. (shrink)

As far as I’m concerned, Korean moral education is facing the new challenge and new era. I’m teaching Korean secondary school studens as an Ethic teacher in high school and EBS lecturer as well. I’m worried about Korean education especially in middle and high school. There was missing thinking those parts cause an entrance examination, only for university in Korea. In this a serious worry, I found some exits from significant experience. First, I’d like to mention about P4C (Philosophy for (...) children) Program which was learned from Professor Mattew Lipman of Mont Clair State University in New Jersey, U.S.A. This program is emphasizing upon thinking skill including creative, critical, and caring thinking. The huge shift from knowledge based education to thinking based education inKorea contemporarily. Also Student-based education is new stream of Korean education system. Teachers think students come to school to get knowledge, parents think children can learn judgment at school which was "lost area.”All this things come from philosophy, when we ask for reason it is a philosophical question. For example, "Why is he a hero?”, “He is brave.” "Why is he brave?" Which is philosophical conceptualization? Every day life gives us some questions and concepts like: love, freedom and philosophy gives us answers to those question so without philosophy we cannot have happy life. In reality of Korean education system there is no independent class for philosophy. So philosophy can be taught in Korean language classes or social studies. I started using P4C program from Lipman: I taught students making questions or making stories. These exercising result was remarkable and amazing. So questions are thebeginning of discovering new knowledge. Even if the knowledge is known by other people students can enjoy the process of discovering new knowledge. They could also get thinking skills. (shrink)

In this study, we examine the relationship between appeal to self-perceptions of moral identity, included in the teaching of ethics, and the strengthening of moral judgment among postgraduate business students. As appeal to moral identity emphasizes personal engagement in the appraisal of an ethically charged situation, it addresses critiques of abstract rule application and principle transfer leveled at traditional business ethics teaching. Eighty-one participants completed a series of reflective writing exercises throughout a twelve-week business ethics unit. Based on an instrument (...) completed at the beginning and end of the education process, our results indicate a positive shift in moral judgement intensity. We, therefore, recommend appeal to moral identity as a leverage strategy to be employed in business ethics education in order to strengthen students’ moral judgment. (shrink)

Multi-modal integration, which combines multiple neurophysiological signals, is gaining more attention for its potential to supplement single modality’s drawbacks and yield reliable results by extracting complementary features. In particular, integration of electroencephalography and functional near-infrared spectroscopy is cost-effective and portable, and therefore is a fascinating approach to brain-computer interface. However, outcomes from the integration of these two modalities have yielded only modest improvement in BCI performance because of the lack of approaches to integrate the two different features. In addition, mismatch (...) of recording locations may hinder further improvement. In this literature review, we surveyed studies of the integration of EEG/fNIRS in BCI thoroughly and discussed its current limitations. We also suggested future directions for efficient and successful multi-modal integration of EEG/fNIRS in BCI systems. (shrink)

The Iowa Gambling Task (IGT) simulates uncertain gains and losses in real life situations and thus is a good measure of uncertain decision making. The role of working memory (WM) in IGT performance still remains unclear. The present study aimed to examine the effect of WM on IGT performance. Three groups of participants matched on gender ratio were randomly assigned to no WM load, low WM load, and high WM load conditions. Initially the three groups did not show significant difference (...) in WM capacity. They finished a modified version of IGT and then their implicit learning effect and explicit cognition on IGT were assessed. Results indicated a linear increasing trend of IGT performance among high WM load, low WM load and no WM load groups; participants in the no WM load and low WM load groups revealed implicit learning effect, while participants in the high WM load group did not; all participants showed explicit cognition on IGT to the same level. These results suggested that participants in the high WM load group showed good explicit cognition to IGT but showed poor performance. This pattern is similar to frontal patients. Further studies should be conducted to explore this issue. (shrink)

I show in this paper how Putnam’s model-theoretical argument can be modified so as to generate a new general tool for Nominalism. I call such a tool “Ockham’s New Razor”.

Section II shows how the technique can be generalized to other cases as well. It also contains a brief discussion of the major assumption in the technique.

Reputation detection in traditional distributed systems relies heavily on the factor of interaction reputation, which can be derived from direct interactions between agents through bidirectional relationships. However, in the current information diffusion in social network systems, the characteristic of the unidirectional relationship between agents and the decay property of diffusion will result in lacking direct interactions; therefore, interaction reputations will be difficult to be obtained by agents in a distributed manner. To solve this problem, a novel distributed reputation detection model (...) following the pattern “from path to individual” is proposed, which can provide a new reputation factor as an alternative to interaction reputation in such environments. The main idea is that the positive observation of an information diffusion process increases the belief of the corresponding diffusion path, which further increases the reputation of each involved agent. Thus, the reputation of a target agent can be assessed by the superimposition of reputations of multiple paths on which this agent has participated in past information diffusion processes. Furthermore, being aware of agent’s limited capacity for reputation detection in SNS, we then propose the enhanced FPTI model, which simplifies the detection source to reduce detection costs and achieve the approximate performance as FPTI. Theoretical analyses and experimental evaluations validate the efficiency and effectiveness of our models and also show several properties of the models, for example, the robustness for dynamic environments.

Recent corporate disgraces and corruption have heightened concerns about ethically questionable behavior in business. The construct of ethically questionable behavior is an under-portrayed area of management field research, and deserves further studying, especially in sales positions. This study uses four variables from the human resource management field to explain the ethically questionable behavior of sales representatives in the pharmaceutical industry. These variables include frame pattern, commission structure, behavior control type, and marketing norm perceptions. This work uses a 2  2 (...)  2  2 subject experimental design, and 328 fully completed questionnaires for logistic regression analysis. Results suggest that a medical representative in a loss frame, in a high commission structure, in loose behavior control, and in a low perception of marketing norm, is more likely affected by heuristic biases and make an ethically questionable choice.

The risk identification system designed in this paper can provide an effective risk identification tool for investors and help them make rational judgments. (shrink)

ABSTRACT What characterizes human reasoning is the ability of dealing with incomplete information. Incomplete logic is developed for modeling incomplete knowledge. The most distinctive feature of incomplete logic is its semantics. This is an alternative presentation of partial semantics. In this paper, we will introduce the general notion of incomplete logic (ICL), compare it with partial logic, and give the resolution method for it. We will also show how ICL can be applied to nonmonotonic reasoning. We define nonmonotonic derivation as (...) monotonic derivation in ICL from the database and some consistent assumptions. The mechanism of ICL makes it easy to assert the consistency of an assumption without asserting the assumption itself. (shrink)
