Brain-computer interface based on steady-state visual evoked potential has been widely studied due to the high information transfer rate, little user training, and wide subject applicability. However, there are also disadvantages such as visual discomfort and “BCI illiteracy.” To address these problems, this study proposes to use low-frequency stimulations, which can simultaneously elicit visual evoked potential and pupillary response to construct a hybrid BCI system. Classification accuracy was calculated using supervised and unsupervised methods, respectively, and the hybrid accuracy was obtained (...) using a decision fusion method to combine the information of VEP and PR. Online experimental results from 10 subjects showed that the averaged accuracy was 94.90 ± 2.34% for the supervised method and 91.88 ± 3.68% for the unsupervised method, which correspond to the ITR of 64.35 ± 3.07 bits/min and 33.19 ± 2.38 bpm, respectively. Notably, the hybrid method achieved higher accuracy and ITR than that of VEP and PR for most subjects, especially for the short data length. Together with the subjects’ feedback on user experience, these results indicate that the proposed h-BCI with the low-frequency stimulation paradigm is more comfortable and favorable than the traditional SSVEP-BCI paradigm using the alpha frequency range.

Cultural values can be considered as important factors that impact parents’ social cognitions and parenting practices. However, few studies compare specific cultural values of parents and the relationships between cultural values and parenting processes in eastern and western contexts. This study examined the ethnicity differences in mothers’ cultural values, parental social cognitions, and parenting practices between Mainland Chinese and European American contexts. Predictors of parenting goals and parenting practices were also investigated. Mothers of 4–6 years old children from the western (...) United States and Shanghai/China participated in this study. The results suggested that mothers from Shanghai/China were both more collectivistic and individualistic than mothers from the western United States. Chinese mothers more strongly endorsed training and collectivistic parenting goals, while European American mothers more strongly endorsed individualistic parenting goals for their children. However, no significant difference was found in parenting practices for both groups of mothers. For both ethnic groups, in general, mothers’ cultural values have small but significant impact on their parenting processes. The prediction of cultural values and parenting goals on parenting practices were also different for both ethnicity groups. Although Chinese mothers were higher on both individualism and collectivism, their collectivistic values were more important in predicting parental social cognitions. (shrink)

Abusive supervision has long been found to have remarkably negative impacts on individual and organizational outcomes. Accordingly, prior studies have explored many organizational and supervisory predictors of abusive supervision and offered several interventions to reduce it. However, extant research lacks the bottom-up perspective to explore how employees can act to reduce abusive supervision, which is an important factor that enriches abusive supervision literature and helps employees protect themselves from being abused. Drawing on self-disclosure theory, we develop a model of whether (...) and how employee boundary blurring behavior may protect them from being abused by their supervisors. Specifically, we conducted two studies to test the theoretical model, including a scenario-based experimental study and a multi-source, multi-wave field study. The results reveal a negative indirect effect of employee boundary blurring behavior on abusive supervision via supervisor liking toward the employee. By uncovering employee boundary blurring behavior as an antecedent of abusive supervision, we enrich the abusive supervision literature with a bottom-up behavioral strategy for employees to proactively protect themselves from being abused. We hope our findings will encourage future studies to identify boundary conditions and other solutions for employees to minimize the risk of being abused. (shrink)

Die neue Buchreihe „Schriftstücke. Jahrbuch für Philosophie und Literaturwissenschaft“ bietet ein Forum sowohl für jüngere als auch für renommierte Wissenschaftler aus beiden Disziplinen. Die Texte widmen sich dem Verhältnis von Philosophie und Literatur in den vielfältigsten Formen. Dabei geht es z.B. um das historische Verhältnis von Philosophie und Literatur, den literarischen Charakter von Philosophie und den philosophischen Gehalt literarischer Texte. Das Jahrbuch möchte ein Ort sein, an dem sich verschiedene Stile und Perspektiven des wissenschaftlichen Argumentierens zwanglos begegnen können. Eine organische (...) Einheit soll sich aus den Beiträgen selbst ergeben, die durch ihre Offenheit für das Fachinteresse aus beiden disziplinären Bereichen gekennzeichnet sind. (shrink)

Companies that use online group-buying to get new business expansion opportunities at a price advantage are failing. Therefore, there is a need to develop new marketing strategies for group-buying companies to achieve market share and consumer favor. Given that consumers are society members, we used the social interaction theory to investigate the combination of factors that stimulate consumers’ purchase intentions. Fuzzy-set Qualitative Comparative Analysis was performed to evaluate different strategy configurations of social interaction elements, perceived quality, benefits and trust to (...) promote purchase decisions from 406 group-buying consumer questionnaires. We revealed four pathways with different configurations that can prompt consumers to make group-buying decisions: information strategy, Word-of-Mouth strategy, sense of community strategy, as well as combining Word-of-Mouth and sense of community strategy. These strategies provide viable approaches through which group-buying companies can rationally use marketing programs to promote consumers’ purchase intentions. (shrink)

In the evaluation of teaching quality, aiming at the shortcomings of slow convergence of BP neural network and easy to fall into local optimum, an online teaching quality evaluation model based on analytic hierarchy process and particle swarm optimization BP neural network is proposed. Firstly, an online teaching quality evaluation system was established by using the analytic hierarchy process to determine the weight of each subsystem and each index in the online teaching quality evaluation system and then combined with actual (...) experience, the risk value of each index was constructed according to safety regulations. The regression model is established through BP neural network, and the weight and threshold of the model are optimized by the particle swarm algorithm. Based on the online teaching quality evaluation model of BP neural network, the parameters of the model are constantly adjusted, the appropriate function is selected, and the particle swarm algorithm which is used in the training and learning process of the neural network is optimized. The scientificity of the questionnaire was verified by reliability and validity test. According to the scoring results and combined with the weight coefficient of each indicator in the online course quality evaluation index system, the key factors affecting the quality of online courses were obtained. Based on the survey data, descriptive statistics, analysis of variance, and Pearson’s correlation coefficient method are used to verify the research hypothesis and obtain valuable empirical results. By comparing the model with the standard BP model, the results show that the accuracy of the PSO-BP model is higher than that of the standard BP model and PSO-BP effectively overcomes the shortcomings of the BP neural network.

Mit seiner Summa Logicae, einer umfangreichen und systematischen Darstellung der aristotelischen Logik, gilt Ockham als einer der größten Logiker des Mittelalters. Dort entwickelt Ockham seine Modallogik zu einer systematischen Größe, die nicht zuletzt mittelalterliche Innovationen und Entdeckungen enthält, wie z.B. Gesetze modaler Aussagenlogik, die Aristoteles nicht kennt. In der vorliegenden Arbeit wird bemüht, solche Aspekte systematisch darzustellen. Der formale Teil der vorliegenden Untersuchung wird durch eine ausführliche semantische Analyse der Modalbegriffe bei Ockham ergänzt, die zeigen soll, wie Ockhams Modallogik mit (...) seiner Ontologie zusammenhängt. Dabei wird für die These argumentiert, daß hinsichtlich der Bedeutung der Modalbegriffe bei Ockham ein Pluralismus vorzufinden ist, der den Schlüssel zur Interpretation von Ockhams Lösung zu dem sogenannten Seeschlacht-Problem bietet, das seit Aristoteles Generationen von Philosophen und Interpreten beschäftigt und zu neuen Entwicklungen der Logik angeregt hat.
