Semantic levels of domain-independent commonsense knowledgebase for visual indexing and retrieval applications

Building intelligent tools for searching, indexing and retrieval applications is needed to congregate the rapidly increasing amount of visual data. This raised the need for building and maintaining ontologies and knowledgebases to support textual semantic representation of visual contents, which is an important block in these applications. This paper proposes a commonsense knowledgebase that forms the link between the visual world and its semantic textual representation. This domain-independent knowledge is provided at different levels of semantics by a fully automated engine that analyses, fuses and integrates previous commonsense knowledgebases. This knowledgebase satisfies the levels of semantic by adding two new levels: temporal event scenarios and psycholinguistic understanding. Statistical properties and an experiment evaluation, show coherency and effectiveness of the proposed knowledgebase in providing the knowledge needed for wide-domain visual applications

The Epistemological Significance and Implications of Belief Polarization

A principal assumption in the epistemology of disagreement is that we, as rational subjects, assess evidence neutrally in order to justify our beliefs. However, the existence of the phenomenon of Belief Polarization threatens the validity of this basis. Since its introduction into philosophical discussion in Thomas Kelly’s paper titled, Disagreement, Dogmatism, and Belief Polarization, the phenomenon of Belief Polarization has been thoughtlessly overlooked. Given serious consideration, there seem to be widespread epistemological implications due to the existence of Belief Polarization. Specifically, Belief Polarization brings to light significant claims about the nature of justification and belief forming processes, specifically concerning evidence gathering. As this paper will argue, given awareness of Belief Polarization, rational subjects should be less confident in their justification of belief forming processes. In other words, rational subjects should not be fully confident in the objectively based truth-value of their beliefs

Comments on ‘A Marxist Critique of the Individual, Rational, Self-Interested, Wealth Maximizer”

This paper brings to light many pertinent observations and claims about the nature of individuals, our relationships to one another, and society as a whole. This paper appears to be deeply concerned with human psychology and the philosophical conditions that characterize it. I plan to focus my comments on both the psychological and normative aspects of the paper: specifically, concerns about the author’s[1] examination of the processes that shape our minds and the prevailing questions that almost certainly follow if these claims are true. In short, I would like to explore further the author’s examination of the human mind and our connections to each other. [1] ‘The author’ always refers to the author of ‘The Marxist Critique

Written emotional disclosure for women with ovarian cancer and their partners: randomised controlled trial.

OBJECTIVE: Written emotional disclosure for 15-20 min a day over 3 to 4 days improves physical and psychological health and may benefit cancer patients. However, no studies have tested the effectiveness of guided writing in cancer patients and their partners. A randomised controlled trial tested whether writing about the patient's diagnosis and treatment of ovarian cancer using the Guided Disclosure Protocol (GDP) is effective in reducing perceived stress and improving quality of life (QoL) in ovarian cancer couples. The study also tested two theories that may account for beneficial effects of written emotional disclosure, the cognitive processing hypothesis and the social interaction hypothesis. METHODS: Patients and their partners (N = 102 couples) were randomised to write at home for 15 min a day over 3 days about the patient's diagnosis and treatment using the GDP or what the patient did the previous day (control). Couples were assessed at baseline, 3- and 6-month follow-ups on the primary outcomes of perceived stress and QoL and secondary outcomes of intrusive thoughts (testing the cognitive processing hypothesis) and illness-related couple communication (testing the social interaction hypothesis). RESULTS: There were no main effects for any outcomes. However, in patients, the GDP improved QoL if illness-related couple communication improved and buffered the effect of intrusive thoughts on perceived stress. CONCLUSIONS: The GDP might benefit patients in certain circumstances, through changes in communication (in line with the social interaction hypothesis). Further research is needed to determine whether patients benefit from interventions to improve illness-related couple communication and under which conditions.

The impact of an emotionally expressive writing intervention on eating pathology in female students

© 2018 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.Introduction: Previous research demonstrating emotional influences on eating and weight suggest that emotionally expressive writing may have a significant impact on reducing risk of eating pathology. This study examined the effects of writing about Intensely Positive Experiences on weight and disordered eating during a naturalistic stressor. Method: Seventy-one female students completed an expressive or a control writing task before a period of exams. Both groups were compared on BMI (kg/m2) and the Eating Disorder Examination – Questionnaire (EDE-Q) before the writing task and at 8-week follow-up. A number of secondary analyses were also examined (to identify potential mediators) including measures of attachment, social rank, self-criticism and self-reassurance, stress and mood. Results: There was a significant effect of intervention on changes in the subscales of the EDE-Q (p = .03). Specifically, expressive writers significantly reduced their dietary restraint while those in the control group did not. There was no significant effect of the intervention on changes in BMI or the other subscales of the EDE-Q (Eating, Weight and Shape Concern). There was also no effect of writing on any of the potential mediators in the secondary analyses. Discussion: Emotionally expressive writing may reduce the risk of dietary restraint in women but these findings should be accepted with caution. It is a simple and light touch intervention that has the potential to be widely applied. However, it remains for future research to replicate these results and to identify the mechanisms of action.Peer reviewedFinal Published versio

Exploring virtual collaborative writing in the EFL classroom

With the integration of new technologies in the foreign language classroom, the practice of collaborative writing has gained renewed attention, although some questions still remain unanswered regarding the extent to which these tools help learners in their writing when compared to more traditional learning contexts (Elola & Oskoz, 2010). In order to explore these issues, we analysed the written production of 84 undergraduate students of English as a Foreign Language (EFL) using the LIWC20154 software. The analysis revealed significant differences in categories such as word count, clout, emotional tone, or analytical thinking when comparing the texts written by an experimental and a control group. Moreover, regarding discourse, some differences were observed in terms of the way information was presented and structuredThis research was funded by the Spanish Ministry of Economy and Competitiveness (EDU2014-54673R

The effects of expressive writing before or after punch biopsy on wound healing

Objective: Recent studies have shown that written emotional disclosure (expressive writing) performed in the two weeks prior to wounding improves healing of punch biopsy wounds. In many clinical settings, it would be more practical for patients to perform this intervention after wounding. The aim of this study was to investigate whether expressive writing could speed the healing of punch biopsy wounds if writing was performed after wounds were made. Methods: One hundred and twenty-two healthy participants aged between 18 and 55 years were randomly allocated to one of four groups in a 2 (intervention) by 2 (timing) design. Participants performed either expressive writing or neutral writing, either before or after receiving a 4 mm punch biopsy wound. Wounds were photographed on day 10 (primary endpoint) and day 14 after the biopsy to measure epithelisation. Participants also completed questionnaires on stress and affect two weeks prior to the biopsy, on the day of biopsy and two weeks after biopsy. Results: There was a significant difference in healing at day 10 between groups, χ2(3, N = 97) = 8.84, p = 0.032. A significantly greater proportion of participants who performed expressive writing before the biopsy had fully reepithelialised wounds on day 10 compared to participants who performed neutral writing either before or after wounding, with no other significant differences between groups. Amongst people who wrote expressively after wounding, those who finished writing over the first 6 days were significantly more likely to be healed at 14 days than those who finished writing later. There were significant differences in positive and negative affect over the healing period between the pre and post expressive writing groups. Conclusions: Expressive writing can improve healing if it is performed prior to wounding. Performing expressive writing after wounding may be able to improve healing depending on the timing of writing and wound assessment. Expressive writing causes affect to worsen followed by subsequent improvement and it is important to consider this in the timing of intervention delivery. Further research with patient groups is required to determine the clinical relevance of these findings

DOI 10.1016/j.ipm.2015.06.003.[EN] In this paper, we investigate the impact of emotions on author profiling, concretely identifying age and gender. Firstly, we propose the EmoGraph method for modelling the way people use the language to express themselves on the basis of an emotion-labelled graph. We apply this representation model for identifying gender and age in the Spanish partition of the PAN-AP-13 corpus, obtaining comparable results to the best performing systems of the PAN Lab of CLEF. © 2015 Elsevier B.V.

Online writing about positive life experiences reduces depression and perceived stress reactivity in socially inhibited individuals

Therapeutic writing can enhance psychological and physical health. Recent studies have suggested that these kinds of interventions can be effective when delivered online. The present study investigated whether positive emotional writing online can influence psychological and physical health in individuals reporting high levels of negative affectivity, who are most likely to benefit from psychological intervention (N = 72, Mage = 28.5, SDage = 8.7), and further, to investigate the potential moderating role of social inhibition. Participants completed self-report measures of physical symptoms, perceived stress, perceived stress reactivity, depression and generalised anxiety, before completing either i) positive emotional writing, or ii) a non-emotive control writing task on an online portal, for 20 minutes per day over three consecutive days. State anxiety was measured immediately after each writing session, and self-report questionnaires were again administered four weeks post-writing. Socially inhibited individuals exhibited significant reductions in depression and perceived stress reactivity four weeks following positive emotional writing, relative to writing about a neutral topic. The present study supports the efficacy of online therapeutic writing in individuals who, due to their socially inhibited nature, are most likely to benefit from online interventions which avoid interaction with a therapist or other clients
