Specification of vertical semantic consistency rules of UML class diagram refinement using logical approach

Unified Modelling Language (UML) is the most popular modelling language use for software design in software development industries with a class diagram being the most frequently use diagram. Despite the popularity of UML, it is being affected by inconsistency problems of its diagrams at the same or different abstraction levels. Inconsistency in UML is mostly caused by existence of various views on the same system and sometimes leads to potentially conflicting system specifications. In general, syntactic consistency can be automatically checked and therefore is supported by current UML Computer-aided Software Engineering (CASE) tools. Semantic consistency problems, unlike syntactic consistency problems, there exists no specific method for specifying semantic consistency rules and constraints. Therefore, this research has specified twenty-four abstraction rules of class‟s relation semantic among any three related classes of a refined class diagram to semantically equivalent relations of two of the classes using a logical approach. This research has also formalized three vertical semantic consistency rules of a class diagram refinement identified by previous researchers using a logical approach and a set of formalized abstraction rules. The results were successfully evaluated using hotel management system and passenger list system case studies and were found to be reliable and efficient

Theatre is a valid add-on therapeutic intervention for emotional rehabilitation of parkinson's disease patients

Conventional medical treatments of Parkinson's disease (PD) are effective on motor disturbances but may have little impact on nonmotor symptoms, especially psychiatric ones. Thus, even when motor symptomatology improves, patients might experience deterioration in their quality of life. We have shown that 3 years of active theatre is a valid complementary intervention for PD as it significantly improves the well-being of patients in comparison to patients undergoing conventional physiotherapy. Our aim was to replicate these findings while improving the efficacy of the treatment. We ran a single-blinded pilot study lasting 15 months on 24 subjects with moderate idiopathic PD. 12 were assigned to a theatre program in which patients underwent "emotional" training. The other 12 underwent group physiotherapy. Patients were evaluated at the beginning and at the end of their treatments, using a battery of eight clinical and five neuropsychological scales. We found that the emotional theatre training improved the emotional well-being of patients, whereas physiotherapy did not. Interestingly, neither of the groups showed improvements in either motor symptoms or cognitive abilities tested by the neuropsychological battery. We confirmed that theatre therapy might be helpful in improving emotional well-being in PD

Consumption of Organic Foods from a Life History Perspective:An Explorative Study among Italian consumers

Taking into consideration individuals’ cognitive reasoning, and assuming that consumption of organic food has involved a change of mind about food experiences and food habits, we have identified the concepts, stories and theories mentioned by respondents in their discourses about organic food. Regular consumers trust organic products because they believe that they are healthier and tastier than any other product. A growing stock of information supports their food choice and confidence in organic food. Occasional consumers have strong beliefs about the better taste and the higher quality of organic food in general. Non organic users sometimes perceive organic food as a new fashion, the last fad. Organic food is still confused with close ‘substitutes’, such as ‘natural’, ‘macrobiotic’ and similar products. Many occasional consumers believe that regular consumers are somewhat obsessed with organic food and that they look and behave strangely. Organic products are generally perceived and experienced as expensive products, when compared to conventional alternatives. To organic consumer the rewards they perceive to gain from organic food is well beyond the resources (in terms of time and money) they employ to search for the higher quality of organic products. Institutional attempts to change consumer behaviour are commonly categorized into consumer information, consumer education and consumer advice (Peter et al., 1999).In order to increase both behavioural and attitudinal loyalty, the level of consumer information and product knowledge should be increased. Besides, consumers will become more committed if their beliefs regarding the intrinsic self-relevance of organic food will increase in the future

“More than just Space” : Designing to Support Assemblage in Virtual Creative Hubs

This paper aims to understand interactions at creative hubs, and how this understanding can be used to inform the design of virtual creative hubs – i.e., social-technical infrastructures that support hub-like interactions amongst people who aren’t spatially or temporally co-located. We present findings from a qualitative field study in UK creative hubs, in which we conducted seventeen observations and ten interviews in three sites. Our findings reveal a range of key themes that define interactions within creative hubs: smallness of teams; neutrality of the hubs; value of the infrastructure; activities and events; experience sharing; and community values and rules. These interactions together form a network and elements that influence one another to make a creative hub more than just physical space. We employ the concept of Assemblage introduced by Deleuze and Guattari to explore this network of interactions and, in doing so, reveal implications for the design of virtual creative hubs that seek to replicate them

A climate terrorism assemblage? Exploring the politics of climate change-terrorism-radicalisation relations

Despite a series of claims from Bernie Sanders (2015), Barack Obama (2015), and others arguing that climate change, radicalisation, and terrorism are connected by complex causal relationships, there is very little academic examination of the politics of these claims. Building on DeLanda's (2006) account of assemblages and social complexity, this paper conceptualises climate change-terrorism-radicalisation relationships as a 'climate terrorism assemblage'. A 'climate terrorism assemblage' is a complex, emergent 'whole' formed from a heterogeneous range of interacting geopolitical components (e.g. climatic factors, migration, think tanks and academic publications, and a discourse of 'climate security'). Specifically, a climate terrorism assemblage is characterised by 'strategic territorialisations': context-specific, multi-scalar points at which political claims of causal links between climate change, terrorism, and radicalisation are crystallised. Strategic territorialisations are produced in two, interrelated contexts. First, using the case study of the Syrian Conflict, a climate terrorism assemblage reveals an intricate, contested politics of ‘drawing lines’ which link climate change, terrorism, and radicalisation. Secondly, the paper argues that, at the points at which causal links are constructed between climate change, terrorism and radicalisation, a climate terrorism assemblage territorialises around intersectional subject formations, in particular a young masculine subject vulnerable to potential radicalisation and terrorism. Overall, the paper concludes that a climate terrorism assemblage provides a productive analytic frame to investigate the contested power relations of climate change-radicalisation-terrorism connections

A smartphone-based health care chatbot to promote self-management of chronic pain (SELMA) : pilot randomized controlled trial

Background: Ongoing pain is one of the most common diseases and has major physical, psychological, social, and economic impacts. A mobile health intervention utilizing a fully automated text-based health care chatbot (TBHC) may offer an innovative way not only to deliver coping strategies and psychoeducation for pain management but also to build a working alliance between a participant and the TBHC. Objective: The objectives of this study are twofold: (1) to describe the design and implementation to promote the chatbot painSELfMAnagement (SELMA), a 2-month smartphone-based cognitive behavior therapy (CBT) TBHC intervention for pain self-management in patients with ongoing or cyclic pain, and (2) to present findings from a pilot randomized controlled trial, in which effectiveness, influence of intention to change behavior, pain duration, working alliance, acceptance, and adherence were evaluated. Methods: Participants were recruited online and in collaboration with pain experts, and were randomized to interact with SELMA for 8 weeks either every day or every other day concerning CBT-based pain management (n=59), or weekly concerning content not related to pain management (n=43). Pain-related impairment (primary outcome), general well-being, pain intensity, and the bond scale of working alliance were measured at baseline and postintervention. Intention to change behavior and pain duration were measured at baseline only, and acceptance postintervention was assessed via self-reporting instruments. Adherence was assessed via usage data. Results: From May 2018 to August 2018, 311 adults downloaded the SELMA app, 102 of whom consented to participate and met the inclusion criteria. The average age of the women (88/102, 86.4%) and men (14/102, 13.6%) participating was 43.7 (SD 12.7) years. Baseline group comparison did not differ with respect to any demographic or clinical variable. The intervention group reported no significant change in pain-related impairment (P=.68) compared to the control group postintervention. The intention to change behavior was positively related to pain-related impairment (P=.01) and pain intensity (P=.01). Working alliance with the TBHC SELMA was comparable to that obtained in guided internet therapies with human coaches. Participants enjoyed using the app, perceiving it as useful and easy to use. Participants of the intervention group replied with an average answer ratio of 0.71 (SD 0.20) to 200 (SD 58.45) conversations initiated by SELMA. Participants’ comments revealed an appreciation of the empathic and responsible interaction with the TBHC SELMA. A main criticism was that there was no option to enter free text for the patients’ own comments. Conclusions: SELMA is feasible, as revealed mainly by positive feedback and valuable suggestions for future revisions. For example, the participants’ intention to change behavior or a more homogenous sample (eg, with a specific type of chronic pain) should be considered in further tailoring of SELMA

Applying machine consciousness models in autonomous situated agents

This paper briefly describes the most relevant current approaches to the implementation of scientific models of consciousness. Main aspects of scientific theories of consciousness are characterized in sight of their possible mapping into artificial implementations. These implementations are analyzed both theoretically and functionally. Also, a novel pragmatic functional approach to machine consciousness is proposed and discussed. A set of axioms for the presence of consciousness in agents is applied to evaluate and compare the various models

Managing in conflict: How actors distribute conflict in an industrial network

IMP researchers have examined conflict as a threat to established business relationships and commercial exchanges, drawing on theories and concepts developed in organization studies. We examine cases of conflict in relationships from the oil and gas industry's service sector, focusing on conflicts of interest and resources, and conflict as experienced by actors. Through a comparative case study design, we propose an explanation of how actors manage conflict and manage in conflict given that they tend to value and maintain relationships beyond episodes of exchange. We consider conflicts in relationships from a network perspective, showing that actors experienced these while adapting to changes in their business setting, modifying their roles in that network. By identifying conflict with the organizing forms of relationship and network, we show how actors formulate conflict through pursuing and combining a number of strategies, distributing the conflict across an enlarged network
