Twitter sentiment analysis with a deep neural network: An enhanced approach using user behavioral information

Sentiment analysis on social media such as Twitter has become a very important and challenging task. Due to the characteristics of such data—tweet length, spelling errors, abbreviations, and special characters—the sentiment analysis task in such an environment requires a non-traditional approach. Moreover, social media sentiment analysis is a fundamental problem with many interesting applications. Most current social media sentiment classification methods judge the sentiment polarity primarily according to textual content and neglect other information on these platforms. In this paper, we propose a neural network model that also incorporates user behavioral information within a given document (tweet). The neural network used in this paper is a Convolutional Neural Network (CNN). The system is evaluated on two datasets provided by the SemEval-2016 Workshop. The proposed model outperforms current baseline models (including Naive Bayes and Support Vector Machines), which shows that going beyond the content of a document (tweet) is beneficial in sentiment classification, because it provides the classifier with a deep understanding of the task.     

Educational privilege: The role of school context in the development just world beliefs among Brazilian adolescents

The purpose of this study is to understand the development of Brazilian adolescents' justice perceptions across different contexts of educational privilege. Past research has found that, in adolescence, the belief in a just world (BJW) differentiates between personal and general and declines. However, prior research has not included adolescents from various socioeconomic statuses, samples in Latin America, or focused on the role of the educational context on the developmental trajectory. Participants were 385 adolescents from 3 schools (private, public and military) in Southern Brazil between 9th and 11th grade. Students completed the personal and general BJW survey. Results revealed a significant interaction of school and grade level of adolescents' personal BJW. Contrary to previous research, personal and general BJW was not always lower in higher grades. Among privileged educational contexts, data indicated that personal BJW may even increase, with the decrease notable in the lower resourced school. In contrast, general BJW was relatively consistent across all Brazilian adolescents. Results provide important insight into the role that privilege and education play across adolescents' development of BJW. This research questions the generalizability of previous studies on the development of BJW and indicates that the trajectory may be dependent upon educational and cultural context.     

Visual context processing and its development in gamers and non-gamers

Visual context processing was investigated in both action video game players and nonplayers using the Ebbinghaus illusion task (N = 312, 39.4% female) in a cross-sectional study design. When presented in context, players showed markedly poorer target size discrimination accuracy compared with nonplayers in the 6-, 7-, 8-, and 9-years old age groups, but this difference was reduced in 10-years old group and diminished in adults. When presented in isolation (no-context), the two groups displayed similar performance in all age groups. Furthermore, nonplayers (linear) and players (bell curve) showed profoundly different age-related differences in context processing. These findings provide evidence that players might have enhanced perceptual bias to process visual context in the transition from early childhood to early adolescence, and the differences between the two groups start at early ages and continue with distinct developmental profiles.     

Organizational context and face-to-face interaction: Influences on the development of trust and collaborative behaviors in computer-mediated groups

Using adaptive structuration theory as a framework [DeSanctis, G., & Poole, M. S. (1994). Capturing the complexity in advanced technology use: Adaptive structuration theory. Organization Science, 5(2), 121–147], we examined the influence of organizational context (competitive versus cooperative) and introductory meeting communication medium (face-to-face versus electronic) on the development of trust and collaborative behaviors of dyads communicating electronically. Based on a sample of 208 senior business students operating in computer-mediated (CM) dyads while performing a strategic decision-making simulation, we found that context, introductory communication medium, and time interacted to influence trust and collaborative behaviors. The pattern of development of trust and collaborative behaviors differed for the same introductory communication medium in different context conditions. Further, the level of trust and collaboration for dyad members in the competitive/electronic introductory meeting condition lagged significantly behind those in the other conditions. The findings suggest that introductory face-to-face interaction plays a more important role in facilitating the development of trust and collaboration in a CM environment when the context is competitive.     

Religion and self-efficacy: a multilevel approach

Can the religious values of an entire geographic area affect the self-efficacy of emerging adults living in that area? Although prior research has demonstrated that individual religious characteristics are associated with self-efficacy, less is known about how the overall religious context influences self-efficacy. Using multilevel analyses on two waves of the National Study of Youth and Religion (NSYR) merged with county-level variables, this study finds that a county’s higher conservative Protestant population share is associated with lower self-efficacy even after controlling for various variables. Surprisingly, this conservative Protestant contextual effect also applies to residents who are not conservative Protestants but live in a conservative Protestant county. In contrast, county-level Catholic population share is linked with higher self-efficacy. However, this Catholic contextual effect is explained when controlling for county-level variables.     

School context and health in adolescence: The role of sense of coherence

The aim of this study was to examine the role of school variables and sense of coherence (SOC) in the explanation of health. For this purpose, data were collected from a representative sample of adolescents, aged 13 to 18 years, selected for the Health Behavior in School‐aged Children survey in Spain. Using Structural Equation Modelling, three nested models were tested that represented different hypothesized models of the relationships among school factors, SOC and health. According to goodness‐of‐fit indices, in the best model, school‐related stress and SOC mediated the influence of support from classmates and teachers on health, and SOC had a direct effect on stress. The results supported the idea that a supportive school climate and SOC are relevant to adolescents' health. Furthermore, SOC was the most influential variable; apart from its direct positive effect on health, SOC seemed to condition the degree to which students perceived school demands to be stressful. Specifically, students with a high SOC were less likely to suffer from high levels of school‐related stress.     

Recognition of context and experience: a civic-based Canadian conception of religious literacy

ABSTRACT

Several conceptions of religious literacy exist globally and are informed by the contextual nuances of the scholars who developed them in the UK, US and Australia. As five Canadian scholar-educators across British Columbia, Alberta, Ontario and Quebec, we analyse the well-known religious literacy conceptions of Jackson, Nesbitt, Dinham, Moore and Crisp through a framework based on the recognition of context and experience. In doing so, we propose a Canadian-specific conception that considers the contextual nuances in these four provinces and relates to Canada as a nation and the individual experiences of each author, and recognises the diversity across Canada. We posit that our conception addresses the social and political dynamics and shifts in Canada, namely the changing demography of religious, spiritual and non-religious individuals and the response to the Truth and Reconciliation Commission report that calls Canadians and its institutions to respond to the wrong towards First Nations, Metis and Inuit people.     

Determining linkages between consumer choices in a social context and the consumer's values: a means–end approach

This paper presents a conceptual model of means–end theory. The proposed model, built on Gutman's (1982) contributions to means–end theory, consists of four conceptual categories that are linked together. The conceptual categories are context‐nested consumer choices, attributes of the consumer choices, consequences and values. The discussion uses results of four cases to illustrate the conceptual categories of the proposed explanatory means–end model. Copyright © 2002 Henry Stewart Publications Ltd.     

Loss context enhances preferences for generosity but reduces preferences for honesty: Evidence from a combined behavioural-computational approach

The current literature has revealed mixed evidence on whether loss (vs. gain) context promotes or curtails human prosociality. The current study (N=96) aimed to address this issue by examining whether gain/loss context has distinct effects on different prosocial preferences combining computational modelling with Dictator Game and Message Game. These interactive games allow for dissociating preferences for generosity and honesty, which have been respectively associated with intuitive and deliberative systems. Our behavioural and computational modelling results indicate that loss context enhances concerns for generosity but reduces concerns for honesty. These findings support an account under the framework of dual process model asserting that loss facilitates intuitive responses during social decision-making, regardless of whether they are prosocial or proself. The current findings reconcile previous debates on the relationship between loss-gain context and human prosociality and shed light on the design of institutions to promote human prosocial behaviours.     

Proactive vitality management in the work context: development and validation of a new instrument

In the present research, we use proactivity literature and studies on energy at work to argue that individuals may proactively manage their vitality (i.e., physical and mental energy) to promote optimal functioning at work. We develop and validate a scale to measure proactive vitality management (PVM), and explore the nomological network. We conducted a five-day diary study (N = 133; 521 days), a survey study (N = 813) and a cross-sectional study measuring daily PVM (N = 246) among working individuals from various occupational sectors. The results show that PVM can be reliably measured with eight items that load on one overall factor, both on general and daily level. Furthermore, daily PVM was moderately but positively related to the use of work-related strategies and micro-breaks. Moreover, PVM related positively to relevant personal characteristics (i.e., proactive personality and self-insight) and showed moderate but positive relationships with job crafting and relaxation (convergent validity). PVM was unrelated to psychological detachment and decreasing hindering demands (discriminant validity). Finally, PVM was positively related to well-being, in-role work performance, creative work performance and performance on the Remote Associates Test (criterion validity). We conclude that employees may promote their own work performance through the use of PVM.     

The paradox of preference for unreliable reinforcement: The role of context and conditioned reinforcement

We discuss Belke and Spetch's (1994) work on choice between reliable and unreliable reinforcement. The studies by Belke and Spetch extend a line of basic research demonstrating that under certain experimental conditions in a concurrent chains procedure, pigeons prefer an alternative that produces unreliable reinforcement. The authors describe the variables that influence preference for unreliable reinforcement, including the signaling and the duration of the reinforcement schedules, the context in which the signaling stimuli occur, and the effects of conditioned reinforcement. Hypothetical applied examples that address these variables are provided, and their influence on preference for unreliable reinforcement in humans is discussed. We conclude by suggesting a line of applied research to examine the relationship between these variables and a preference for unreliable reinforcement.     

Constructing autobiographical events within a spatial or temporal context: a comparison of two targeted episodic induction techniques

ABSTRACT

Recalling and imagining autobiographical experiences involves constructing event representations within spatiotemporal contexts. We tested whether generating autobiographical events within a primarily spatial (where the event occurred) or temporal (the sequence of actions that occurred) context affected how the associated mental representation was constructed. We leveraged the well-validated episodic specificity induction (ESI) technique, known to influence the use of episodic processes on subsequent tasks, to develop variants that selectively enhance spatial or temporal processing. We tested the effects of these inductions on the details used to describe past and future autobiographical events. We first replicated the standard ESI effect, showing that ESI enhances generating episodic details, particularly those that are perception-based, when describing autobiographical events (Experiment 1). We then directly compared the effects of the spatial and temporal inductions (Experiment 2 and 3). When describing autobiographical events, spatial induction enhanced generating episodic details, specifically perception-based details, compared to the control or temporal inductions. A greater proportion of the episodic details generated after the temporal induction were gist-based than after the spatial induction, but this proportion did not differ from a control induction. Thus, using a spatial or temporal framework for autobiographical event generation alters the associated details that are accessed.     

Religion and youth educational aspirations: a multilevel approach

Previous research has demonstrated that individual religious beliefs and practices are associated with educational outcomes. However, less is known about the manner in which the overall religious cultural influence of a religion can affect an individual’s educational aspirations. Using multilevel analyses on two waves of the National Study of Youth and Religion (NSYR) merged with county-level variables from the US Census, and the Religious Congregations and Membership Study (RCMS), the study shows that a county’s higher Jewish population share is associated with a higher level of educational aspirations for the youth, regardless of being Jewish or not. This Jewish contextual effect remains robust even after controlling a wide range of individual and county-level variables, such as individual academic achievement and religious identity. Consistent with the relevant theory and literature, the negative main effect of county-level conservative Protestant population share on educational aspirations is explained by county-level socioeconomic characteristics. The same mechanism is used in part to explain the initially positive relationship between Catholic population share and educational aspirations. Finally, the study highlights the importance of using a multilevel approach to examine and provide understanding of the relationship between religious influence and educational outcomes.     

Revisiting interreligious relations: The convergence of global context and ecclesial developments

Following the important work of the 1980s and 1990s by the US churches and ecumenical bodies in developing interfaith statements and policies, significant events in both the US and international arenas were coincidental and motivational for US Christians to reconsider their interreligious engagement in a new context. This article examines the major contextual factors, as well as ecumenical developments with particular attention to the United Church of Christ and the National Council of Churches, which also will consider new statements in 2019.

The role of the native language in auditory and visual context effect modalities

Facilitation of memory for target stimuli due to similar context in the learning and testing phases is known as “context effect” (CE). The present study aimed to investigate the interaction between CE as elicited by the consistency of the language of presentation (Hebrew vs. English) with the native language (Hebrew vs. English) in both auditory and visual modalities. Overall, 120 individuals participated in the experiment. As predicted, CE was evident when the language of presentation remained consistent between study and test. Contrary to our prediction, Hebrew speakers remembered more English words, and vice versa. A possible explanation is that this difference is due to the cognitive effort invested when processing a less dominant language, thus resulting in better recognition. This study has several practical implications, including a recommendation that academic institutions test students in the language in which the material was presented in order to measure the students' knowledge more accurately.     

Context reinstatement and memory for intrinsic versus extrinsic context: The role of item generation at encoding or retrieval

According to many theoretical accounts, reinstating study context at the time of test creates optimal circumstances for item retrieval. The role of context reinstatement was tested in reference to context memory in several experiments. On the encoding phase, participants were presented with words printed in two different font colors (intrinsic context) or two different sides of the computer screen (extrinsic context). At test, the context was reinstated or changed and participants were asked to recognize words and recollect their study context. Moreover, a read‐generate manipulation was introduced at encoding and retrieval, which was intended to influence the relative salience of item and context information. The results showed that context reinstatement had no effect on memory for extrinsic context but affected memory for intrinsic context when the item was generated at encoding and read at test. These results supported the hypothesis that context information is reconstructed at retrieval only when context was poorly encoded at study.     

Exploring diversity effects: nationality composition and nationality context in workgroups

The types of conflict that emerge in nationally diverse teams may depend on the number and types of nationalities present in the team. We investigate the possibility that when teams have individuals from multiple different nationalities (i.e., Dutch, Swiss and Indonesian), rather than just two different nationalities (Dutch and Indonesian), performance and task conflict will be higher while process and relationship conflicts will be comparatively lower. A scenario-based study was conducted in two countries in which we examined how nationality composition (size of national diversity or number of nationalities) and context (nature of national diversity or types of nationalities) affected perceived conflict and expected performance. We hypothesized and found that task conflict and performance are higher in nationally diverse workgroups that included multiple dissimilar nationalities compared to workgroups with just two nationalities. Results also showed that relationship and process conflicts are lower in groups that are diverse in size and nature of national diversity. We observed that social distances among nationalities varied in such a way that a distant nationality became more distanced and a close nationality became even closer in a nationally diverse group. Social distance, in that way, moderated the effect of national diversity. We discuss implications for diversity and conflict management.     

行动语义、客体背景和判断任务对客体动作承载性的影响

客体动作承载性指人们知觉客体时同时激活的针对客体的行动。当Gibson最初提出动作承载性概念时, 他认为客体的这种属性是可以自动激活的。然而近年来越来越多的证据显示, 在知觉和行动的关系中, 行动语义知识和客体所处背景对客体动作承载性具有调节作用, 表现在人们可以根据这些自上而下的信息选择针对客体的适当的行动。此外, 不同的判断任务在引发客体动作承载性效应上具有特异性, 表现在若判断任务仅需知觉客体表层属性时, 不能激活对客体的动作, 进而不能产生客体动作承载性; 若判断任务需要对客体进行深层加工时, 才会激活对客体的动作。未来研究还需要进一步探究行动语义知识和客体所处背景影响客体动作承载性发生的原因和机制, 以及不同判断任务中出现结果特异性的原因。
