Price discovery and volatility spillover with price limits in Chinese A-shares market: A truncated GARCH approach

Abstract The use of price limits by a stock exchange means that the distribution of returns is truncated. By considering a GARCH model in conjunction with a truncated distribution for the residuals, this study investigates whether price limits have an effect on price behaviour and volatility of Chinese A-shares. The analysis has been applied to A-shares traded on the Shanghai Stock Exchange (SSE) and the Shenzhen Stock Exchange (SZSE) during the period from 2004 to 2018. The results suggest the Truncated-GARCH model outperforms a conventional model and offers substantially different insights into the effect of price limits. The delayed price discovery hypothesis is not rejected for either exchange after upper price limit hits. Limited evidence supports the volatility spillover hypothesis, as just over 5% of A-shares experience an increase of volatility after upper price limit hits on both exchanges. No evidence of reduction of volatility after price limit hits is shown in the research.
Multikonferenz Wirtschaftsinformatik 2018: Data driven X — Turning Data into Value

Cyber threat intelligence is obtained in an unstructured and ad-hoc manner from publicly available cyber security information sources such as security expert blogs or mailing lists. Although these information sources are used by employees as input for critical information security and risk management processes, they often have not received any formal IT department approval or assessment which raises issues in analogy to phenomenon of shadow IT. Little is known about the actual value these cyber security information sources provide and how they complement information security and risk management processes. In this paper, we conduct a structured, in-depth analysis of shadow cyber threat intelligence and investigate how it is used in organizations. Our study revealed that many heterogeneous and overlapping cyber security information sources serve as input for information security and risk management processes and that the obtained shadow threat intelligence is shared internally in a largely unstructured and informal manner.
An Exploration of the Nature and Prevalence of Substance Use in a Forensic Population and an Evaluation of its role in Recall to Hospital

Part one of this major research project is a systematic review of the research into the psychological effects of synthetic cannabinoid (SC) use. This relatively new phenomenon continues to be a problem in specific populations despite attempts by the UK government to control distribution of SCs. The review highlights the paucity of rigorous, controlled research, whilst summarising the findings from an experimental study, cross-sectional research, internet surveys and qualitative interviews. There is evidence of an association between acute and prolonged SC use and a broad spectrum of psychological effects, including higher scores on anxiety and depression measures and impaired cognitive inhibition and long-term memory. Suggestions for future research are discussed. Part two is an empirical paper describing a study assessing the prevalence of alcohol and other drug use in a forensic population. It also examines the role of alcohol, cannabis, SC and crack in recall to hospital following conditional discharge. Substance use was assessed retrospectively across four time points in a group of patients who had been formally recalled to hospital and in a group who remained on conditional discharge. The results suggest both alcohol and cannabis use may be important factors for outcomes following conditional discharge. The findings are discussed as well as the strengths and limitations of the study. Part three is a reflection and critical appraisal on the undertaking of the major research project. It addresses some of the challenges that arose during the research process in the designing of measures, acquiring ethical approval and recruitment. It ends with a discussion of power, beyond statistics, in the research process.
A Culture of Success: Black Alumnae Discussions of the Assets-Based Approach at Spelman College

ABSTRACT Some campuses are exemplars for best practices for racial inclusion in higher education, and they offer a vital opportunity to understand how to better include Black students. This critical life story analysis of Black college alumnae who graduate from a historically Black, women’s institution, Spelman College, demonstrates the importance of fostering success throughout a student’s college experience. The findings suggest that Spelman offered a deliberate and systematic culture of success from the beginning to the end of the women’s experiences offering lessons that could be adapted within other institutional types in order to foster the success of Black students.
Reciprocal Personality Assessment of Both Partners in a Romantic Relationship and Its Correlates to Dyadic Adjustment

This project examines the effects of self- and partner-rated personality and their reciprocal interaction between two partners. Personality in 113 young dating couples was measured with the Five-Factor Model and maladaptive personality trait model of the DSM-5. Partners completed self- and partner-reports of the NEO-FFI-3 and the Personality Inventory for DSM-5 (PID-5) as well as the self-report Dyadic Adjustment Scale (DAS). Three sets of Actor-Partner Interdependence Models (APIMs) were run to estimate actor and partner effects of self-rated personality, partner-rated personality, and of both sets of effects simultaneously in an integrated model. When self- and partner-rating models were examined separately, several significant actor and partner effects were observed. However, the strongest effects were observed in the partner-rating models. When self- and partner-rated personality were examined at the same time, most effects from the self-rating models disappeared. Furthermore, most of the effects as well as the strongest one observed were associated with an individual’s perception of their partner’s personality, particularly men’s perception of women’s personality. This study demonstrates the incremental predictive utility of individuals’ perception of their partner’s personality for explaining their own dyadic adjustment.
An Autoethnography of a Language Teacher Educator: Wrestling With Ideologies and Identity Positions.

I write this autoethnography to narrate and analyze the important episodes in my life’s history, learning and teaching English in my home country and preparing teachers to work with emergent bilinguals in the United States. I frame this autoethnography within the burgeoning strand of self-studies of language teacher education and the research on the education of preservice bi/multilingual teachers. I use language ideologies as a conceptual lens in my narrative to interpret my experiences negotiating identities as a language user, teacher, and teacher educator. I hope that this autoethnographic analysis of my experiences as an early-career transnational scholar will contribute to the conceptualization of the complex processes of teacher educator identity construction and resonate with other teacher educators who serve preservice bi/multilingual teachers.

Accommodation providers’ motives in sharing economy: comparison between Turkey and Lithuania

The purpose of this paper is to empirically assess and compare motivations and moderating factors that influence intention to provide accommodation in two countries, which are different in terms of their culture and IT infrastructure development. ,Empirical analysis on the basis of 396 valid questionnaires from two countries allowed finding two different models that explain intentions to provide accommodation in the analyzed environments. Subsequent multilevel modeling disclosed differences between influences on intention to provide accommodation in Turkey and Lithuania. ,The results disclosed importance of country contexts in causing diversity between country-specific models and in generating differences of the influences, if the same model for two countries is applied. The most important findings include observed differences in influences of monetary and social motives on intention, as well as in moderations of materialism and mavenism. ,Using the self-determination theory as the theoretical background, the study adds to the knowledge on intention to participate in sharing economy from the accommodation providers’ position. Additional value is brought by finding the importance of cultural contexts in the models that describe intentions of accommodation providing in sharing economy.
Teaching in culturally and linguistically diverse classrooms: Turkish EFL instructors’ experience

This study investigates Turkish EFL instructors’ perceptions regarding their readiness for and potential challenges that they face in classrooms with students from diverse cultural and linguistic backgrounds. Using both quantitative and qualitative methods of inquiry, data were collected by utilizing the Multicultural Teaching Competency Scale (MTCS) (Spanierman, Oh, Heppner, Neville, Mobley, Wright, Dillon, & Navarro, 2011) and semi-structured interviews. The findings acquired from the scale revealed that the majority of the participating instructors perceived themselves as competent, yet further inquiry through the interviews indicated that they feel challenged while meeting the academic and linguistic needs of diverse group of students as they lack relevant formal training. The study calls for an urgent need to make provision for training programs designed to increase instructors’ awareness, knowledge and skills to work effectively in culturally and linguistically diverse education contexts.
Is One Study as Good as Three? College Graduates Seem to Think So, Even if They Took Statistics Classes

When people interpret the outcome of a research study, do they consider other relevant information such as prior research? In the current study, 251 college graduates read a single brief fictitious news article. The article summarized the findings of a study that found positive results for a new drug. Three versions of the article varied the amount and type of previous research: (a) two prior studies that found the drug did not work, (b) no prior studies of the drug, or (c) two prior studies that found the drug had a positive effect. After reading the article, participants estimated the probability the drug is effective. Average estimates were similar for the three articles, even for participants who reported more statistics experience. Overall, just 4% of participants appeared to use prior research to make probability estimates—most seemed to focus on the latest study, while ignoring or discounting prior studies. Implications for statistics education and reporting are discussed.
Perceptions of the Effects of Augmented Reality in the Classroom.

Augmented reality continues to be lauded as a disruptive innovation in education. This research examines the perspectives of AR using educators who are Innovators and First Adopters in Roger’s Diffusion of Innovation Scale. Attitudes towards AR were examined through a survey that included Likert-scale items and open-ended qualitative items. Results appear to show that educators were largely using downloadable AR apps, but found them highly engaging and enjoyable with students. A few teachers indicated that they or their students were also creating AR using a variety of platforms. Inferential analyses were also employed, but found no differences between groups. Issues and challenges in using AR are also discussed.
Parenting Profiles of Young Low-income African American and Latina Mothers and Infant Socioemotional Development

SYNOPSIS Objective. Parenting styles are complex and have been well studied in parents of children and adolescents; however, less is known about parenting styles in early infancy, especially among ethnic minority groups. This study examines empirically identifiable profiles of early parenting that are associated with later infant socioemotional development. Design. 239 young, low-income, African American (54.8%) and Latina (45.2%) mothers were videorecorded with their 3-month-old infants. At 13-months, mothers reported on their infants’ socioemotional development. Results. Person-oriented latent class analysis was used to identify four parenting styles: Sensitive/Stimulating (25%), Warm/Unstimulating (37%), Engaged/Tough (22%), and Disengaged (16%). The most common style among African American mothers was Engaged/Tough (34.4%), and the most prevalent style among Latina mothers was Warm/Unstimulating (48.2%). Infants of Warm/Unstimulating mothers had the lowest reported levels of problem behavior at 13 months, whereas infants of Sensitive/Stimulating mothers had the highest reported mastery motivation. Infants of Disengaged mothers had the highest reported levels of internalizing and total problem behavior and the lowest reported mastery motivation. Conclusions. Qualitatively distinct styles of early parenting link to different infant socioemotional outcomes in ways not fully captured by single dimensions of parenting. Practitioners working with young mothers from diverse ethnic backgrounds may be more effective at promoting positive parenting and infant development if they understand and can build on the strengths of certain parenting styles.
No pain, no gains: Conformity to masculine norms, body dissatisfaction, and exercise dependence.

Although exercise can facilitate physical and mental health, excessive exercise can be deleterious to men’s health. While there is a wealth of research on the link between body image concerns and excessive exercise among women, this relationship remains understudied among men. In addition, gender role socialization’s role in excessive exercise remains overlooked. Therefore, the present study examined how body dissatisfaction (i.e., muscle and body fat dissatisfaction) may mediate the effect of conformity to specific masculine norms on self-reported exercise dependence (i.e., uncontrollable excessive exercise behavior that manifests in physiological and psychological symptoms) using a sample of 632 U.S. community men who were primarily white and heterosexual. Results indicated that muscle dissatisfaction, but not body fat dissatisfaction, mediated the effects of the norms of Winning, Violence, and Playboy on exercise dependence. Winning, Emotional Control, Risk-Taking, and Power Over Women also evidenced direct effects on exercise dependence. Implications for practice and the importance of testing the generalizability of this model across social locations are discussed.
Asymmetric Driver Behaviour-Based Algorithms for Estimating Real-Time Freeway Operational Capacity

To mitigate recurrent and non-recurrent congestion, and to make full use of limited roadway capacity, numerous Active Traffic Demand Management (ATDM) strategies have been proposed, developed and implemented. Segment capacity, a basic input of ATDM predictive models, has been commonly considered a fixed value; however, this consideration does not allow for the probability that complex segment capacity may vary as prevailing traffic conditions vary. Limited research was found that develops analytical models for real-time capacity estimation. This thesis proposes an asymmetric driver behaviour-based algorithm to model multi-lane traffic flow dynamics. By considering car-following and lane-changing behaviours at critical freeway segments, i.e. active bottlenecks and Variable Speed Limit (VSL)-controlled segments, the proposed method obtains real-time freeway operational capacity estimation. The model parameters have been calibrated with field observations taken in Edmonton, Alberta, Canada. The results show that the proposed algorithm accurately estimates real-time operational capacity at complex freeway segments.
Breaking down the barriers to operator workload estimation: Advancing algorithmic handling of temporal non stationarity and cross participant differences for EEG analysis using deep learning

Accurate assessment of operator mental workload in the flight environment could enable a myriad of benefits including improved training and safety. Typically when measuring operator functional state, a variety of psychophysiological features are collected and aligned with the associated operator state at a given time. Then signal processing and machine learning techniques are used to train models and make predictions about the operator’s state based on the sensor data. The electroencephalograph (EEG) is a useful mental workload sensor because it directly measures brain state, is portable, and provides excellent temporal resolution. However, several barriers exist to using EEG data for workload assessment in operational settings. This research focuses on two barriers: 1) Temporal non-stationarity in feature-to-target mappings when using EEG data, commonly known as day-to-day variability, 2) The myriad of individual differences which lead to cross-participant applicability challenges–a model trained on one individual may not work well for another. Several signal processing techniques and deep learning approaches are developed and evaluated in multi-task environments which account for temporal, spatial, and frequential data dependencies. Application of these techniques and approaches yield the following findings: 1) Incorporating a new feature–variance of Power Spectral Density (PSD) distributions for cross-day workload classification significantly improves classification accuracy. 2) PSD skewness and kurtosis are not significant in an environment absent of workload transitions, but are salient when workload transitions are present. 3) Long Short-Term Memory (LSTM) networks decreased classification error by 59% compared to the previously best results in the presence of day-to-day non-stationarity. 4) A convolutional-recurrent model using multi-path subnetworks and bi-directional,
