A systematic comparison of roundtrip software engineering approaches applied to UML class diagram

Model-based software engineering contemplates several software developments approaches in which models play an important role. One such approach is round-trip engineering. The objective of this paper is to benchmark the comparative analysis of the round-trip engineering capability of three modelling tools: Papyrus, Modelio and Visual Paradigm. The conclusions drawn throughout the paper will answer the question: How effective are current code generation tools for documenting application evolution? Throughout the discussion, we have pointed out several improvements that these UML modelling tools have recently brought to the discussion. We have also proposed some improvements that we consider desirable to improve Roundtrip Engineering approaches pointing out possible directions and solutions.info:eu-repo/semantics/publishedVersio

Toward a circular supply chain:The enabling role of information and financial flows in open and closed loop designs

Paramount to the transition to the circular economy is the transformation of existing supply chains. We build on the theory of the supply chain to study circular design features and the enabling role of information and financial flows needed for circularity. We study five exemplars for environmental leadership to illuminate how material flows are enabled by information and financial flows to leverage cross-industry waste flows (i.e., open loops) and customer returns (i.e., closed loops). While both open and closed loop designs can lead to a bottom-up transition towards the circular economy, there are differences in the enabling role played by outward and inward information flows. Further, we unpack the supporting role of inward and outward financial flows toward customers, suppliers and non-supply chain stakeholders for creating a viable supply and demand circular market and a wider community in which circular supply chain can be embedded

Doing the Work that Makes All Work Possible: A Research Narrative of Filipino Domestic Workers in the Tri-state Area - Executive Summary

DAMAYAN Migrant Workers Association, in partnership with the Community Development Project of the Urban Justice Center, engaged in this multi-year study to understand the plight of Filipino domestic workers living in the tri-state area. The study utilized a community-based participatory action research approach (CBPAR). From inception to release, domestic workers, their children, staff members and volunteers have been involved in multiple levels of this research. Domestic workers were purposefully involved in the analyzing, writing and designing of the report. While there are volumes of literature written about the conditions of Filipino domestic workers worldwide, few studies focus on the migration and labor of Filipino domestic workers in the US; and none have made Filipino domestic workers comprehensively integral to the CBPAR process such as this one

Optimization of radio-therapeutic treatment and the program of quality assurance in ionizing radiation therapy

National Center of Public Health, Chisinau, the Republic of MoldovaBackground: The Program of Quality Assurance (PQA) in Ionizing Radiation Therapy (IRT) addresses the most important problems of assuring the quality of IRT utilization in the treatment of patients with neoplasm. In this context, the IRT value grows considerably, hence the implementation of PQA is of great significance. The study concentrates on a detailed description of the PQA as concerns the activity involving IRT devices applied in the IRT departments (rooms) of public medical/sanitary institutions, science research institutions etc., where IRT is employed using technogenic sources and ionizing radiation generators. Material and methods: For the performing of the study, annual statistics reports about the activity of the IRT, and data of Cancer Registry of the Oncologic Institute of the Republic of Moldova were analyzed. The work also includes an in-depth description of the personnel categories involved in PQA, possible errors in radiotherapy, the responsibilities of the bioengineer in this program, importance of source calibration, the impact of the quality control in PQA, the role of topometric training, the interaction between the medical and technical personnel and the patient. Conclusions: Optimization of IRT is very important and necessary in the Republic of Moldova. PQA incontestably contributes to reducing specialist’s errors in planning correct treatment, dictates the need of team work and proper delegation of the responsibilities in co-optation of other professionals, performance of duty of bioengineering, the influence of quality control of profile installations, meaning accurate topographic planning, applying several methods of work, quality assurance program assuming the major importance

Geometry of General Hypersurfaces in Spacetime: Junction Conditions

We study imbedded hypersurfaces in spacetime whose causal character is allowed to change from point to point. Inherited geometrical structures on these hypersurfaces are defined by two methods: first, the standard rigged connection induced by a rigging vector (a vector not tangent to the hypersurface anywhere); and a second, more physically adapted, where each observer in spacetime induces a new type of connection that we call the rigged metric connection. The generalisation of the Gauss and Codazzi equations are also given. With the above machinery, we attack the problem of matching two spacetimes across a general hypersurface. It is seen that the preliminary junction conditions allowing for the correct definition of Einstein's equations in the distributional sense reduce to the requirement that the first fundamental form of the hypersurface be continuous. The Bianchi identities are then proven to hold in the distributional sense. Next, we find the proper junction conditions which forbid the appearance of singular parts in the curvature. Finally, we derive the physical implications of the junction conditions: only six independent discontinuities of the Riemann tensor are allowed. These are six matter discontinuities at non-null points of the hypersurface. For null points, the existence of two arbitrary discontinuities of the Weyl tensor (together with four in the matter tensor) are also allowed.Comment: Latex, no figure

Evaluation of Left Atrial Size and Function: Relevance for Clinical Practice

Left atrial (LA) structural and functional evaluation have recently emerged as powerful biomarkers for adverse events in a variety of cardiovascular conditions. Moreover, noninvasive evaluation of LA pressure has gained importance in the characterization of the hemodynamic profile of patients. This review describes the methodology, benefits and pitfalls of measuring LA size and function by echocardiography and provides a brief overview of the prognostic utility of newer echocardiographic metrics of LA geometry and function (i.e., three-dimensional volumes, longitudinal strain, and phasic function parameters)

Bea score study and correlations with the survival of surgical position conclusions

Purpose: To evaluate the applicability of Baseline Event Anticipation score (BEA), as a prognostic factor for complications in cases of cirrhotic patients. Material and Methods: Population chosen for the study was represented by patients suffering from cirrhosis, being evaluated through BEA prognostic score sensibility, using the online formula.(http://hepatitis –delta/org/physicians-and-scientists/calculator). Results: The lot of operated patients where 54, with an average age of 43.4 ± 4.3 years; 53% of them were male and 47% female. All patients had Azygo-Portal Devascularization Hassab-Kaliba, histologically distributed as : micronodular hepatic cirrhosis - 24 (44.4%) macronodular- 16 (29.6%) and micro-macronodular - 14 (25.9%). In the analysis was a prevalence of the BEA-B score - 21 cases (38.9%), followed by 17 cases (31.5%) with BEA-A score and 16 cases (29.6%) with BEA-C score. After surgery 7 patients had 15 complications: early (6) and late (9), surgical (3) and therapeutic (12). Comparing the results, there is a direct correlation, r = 0.233 of the BEA-C score with the incidence of complications, and a decrease in BEA-A and BEA-B patients. Conclusions: This retrospective study was conducted in a specialized center with a reduced sample size, it demonstrates the prognostic utility of the BEA score and apparently requires care that will improve perioperative recovery, and will reduce morbidity

A Multilevel Analysis of Implicit and Explicit CSR in French and UK Professional Sport

Research question: This paper examines the ways in which French and UK professional sports clubs implement and communicate their CSR policies. In addition to identifying similarities and differences between CSR practices in the two countries, our analysis extends and adapts the implicit-explicit CSR framework to the field of sport. Research methods: We used a mixed methods approach to analyse qualitative and quantitative data on the CSR strategies of 66 professional rugby union (Top 14, Aviva Premiership Rugby) and football (Ligue 1, Premier League) clubs over the 2017-2018 season. Results and findings: We found major differences in CSR communication between France and the UK. Communication by French clubs tends to highlight sport’s values, involve few media channels, whereas communication by UK clubs explicitly vaunts their social responsibility and involves numerous channels. In the case of CSR implementation, there are similarities between French and UK clubs, especially in the fields their CSR initiatives cover (e.g., health, diversity), as well as differences. However, the scope of initiatives varies more between sports than between countries, with football demonstrating a more international outlook than rugby. Implications: This article expands Matten and Moon’s (2008) implicit-explicit CSR framework by identifying the influence of interactions between sectorial/field-level factors and national/macro-level factors on CSR practices, and by distinguishing between CSR communication and CSR implementation. Our results throw light on the shift from implicit to explicit CSR in French professional sport
