he paper considers a possibility to apply gravity models for calculation of intercity passenger transport corres- pondences which are implemented with the help of public transport. The Ukraine transportation system has been selected as an object of investigation and this approach extends application possibilities of the obtained results. Calibration coefficients used in calculation of the indicated correspondences are rather important and significant in case of forecasting passenger transport correspondences. Formalization of these factors is necessary for every transportation system if a calculation of pas-senger transport correspondences has been made for it. In this case searching for actual calibration parameters and other coef-ficients as components of gravitational models is a relevant objective of the given paper. Selection of the gravity model va- riant plays rather significant role in solution of this problem. The developed methods for calculation of passenger transport correspondences are proposed for their application in respect of various transport and trip types. The executed research works have made it possible to investigate a process pertaining to providing of services for passenger transportation while using public routes. The obtained characteristics on functioning of the studied system have allowed to assess the possibility for ap-plication of the known methods for calculation of passenger correspondences and analyze the quality of their application. Calibration coefficients have been empirically selected for calculation of the indicated correspondences while using method of gravity modeling. Formalization of previously unexplored parameters of gravity model component provides the possibility to apply the considered approach for calculation of passenger correspondences within the framework of the investigated trans-portion system. This makes it possible to plan and arrange interaction of various transport types and provides new data and knowledge on the studied system.

This chapter returns to the overarching questions of this book, namely, how can national energy transitions be explained, to what extent do patterns of change align and differ in the transitions of this study, and how does policy play a role, particularly with innovations that emerged amid the transitions. To broadly answer, the four cases are comparatively examined here. The conceptual tools from Chapter 3 are also elaborated based on the findings. Implications of the results are discussed, and will serve as a basis for further discussion in Chapter 9 on how to think about energy transitions as a planner, decision-maker, and researcher. Among the more significant findings are the following. Greater energy substitution (in relative terms) occurred initially within the countries that extended or repurposed existing energy systems versus the country (i.e., Denmark) that developed a new energy system from a nearly non-existent one. Cost improvements were evident in all cases; however, a number of caveats are worth noting. Among the energy technologies and their services that were studied, only Icelandic geothermal-based heating was competitive in its home market in the 1970s; nonetheless, the remaining energy technologies that were studied later became cost competitive. As the national industries of this book became globally recognized, increases in the quality of living within the given countries also occurred, as gauged by the Human Development Index (HDI). With respect to timescales, substantial energy transitions were evident in all cases within a period of 15 years or less. In terms of technology complexity, this attribute was not a confounding barrier to change. Finally, government was instrumental to change, but not always the driver. There are countless ways to compare national energy transitions. This section illustrates ways of doing so, first by describing broadly observed, socio-technical patterns with the tool typologies outlined in Chapter 3. A discussion of tool refinement follows. The section then turns to more systematically assess key, qualitative and quantitative dimensions of the four transition cases.

Abstract The Diverse Elders Coalition, in partnership with its six member organizations and the Benjamin Rose Institute on Aging, completed a national survey of 840 family and friend caregivers from diverse racial, ethnic, and sexual orientation communities to understand their unique caregiving issues and challenges. Data from a subsample of 369 caregivers identifying as Hispanic/Latino, Asian, Southeast Asian or multiple ethnicities were analyzed to understand similarities and differences between caregivers born in the US and who immigrated to the US. The Stress Process Conceptual Model guided selection of characteristics used for comparative analysis. Results of logistic regression revealed that caregivers born in the US were younger (B=-.08, p<.001), had higher educational degrees (B=.42, p<.001), and higher incomes (B=.34, p=.002). They assisted care receivers with more health-related tasks (B=.27, p=.013), but fewer culture-related tasks (B=-.51, p=.002); reported higher levels of strain in their relationship with care receivers (B=.66, p=.038); and were less satisfied with the quality of care receivers’ healthcare (B=-.62, p=.042). In terms of reasons for being a caregiver, there were no significant differences in cultural commitment to caring for older family members, however those born in the US were more likely to report providing care because it was more convenient for them than for other family and friends (B=.99, p=.002). Understanding the needs of diverse caregivers has implications for healthcare and service providers, such as providing training on diverse needs. Additionally, the differences between US born and immigrant caregivers highlights implications on the dynamic between caregivers and their care receiver.

The article is devoted to the assessment of the contractor companies activity in the field of safety both before the start of work execution and during the execution of work at the construction site of the Client’s company. Analysis is given concerning the industrial injuries from 2009 to 2018 in Russia, based on which the tendency to reduce industrial injuries for the current period is determined, and the coefficients of the frequency of injuries in various countries for 2015 are calculated. Based on the performed analysis, the injury rate in Russia is still at a high level. Economic component for the materials, personnel qualifications, and savings on safety from the Client’s company can also lead to injuries at the construction site. The main reasons for low quality of the work performed at the construction site, which in turn lead to injuries, are given in the article. Matrix for the assessment of the contractor companies was developed, with the help of which it is proposed to assess all the aspects of their activities that effect on safety of the work performed. Among the assessed aspects there are sections related to training, behavior and motivation of the personnel, audits conducted by the contractor companies in relation to the subcontractors, investigation of incidents by using the current procedures and contractor personnel responsibilities. One of the matrix elements is presented for assessment. Each element from the given section is proposed to be assessed on a scale from 0 to 3, where each aspect is presented in the form of an action, an assessment of this action and its result. Recommendations on the use of this methodology in the selection of contractors are provided.

Abstract Background Detection and selection of the lymphatic vessels are important for maximizing therapeutic efficacy of lymphaticovenular anastomosis (LVA). Some imaging modalities have been reported to be useful for intraoperative identification of the lymphatic vessels, but they have limitations. In this article, we present new capabilities of intraoperative laser tomography, which was used to evaluate the lumen of the lymphatic vessel and to validate the patency of anastomosis. Patients and Methods Fifty-two patients with upper extremity lymphedema secondary to breast cancer treatment underwent indocyanine green (ICG) lymphography and real-time laser tomography imaging of ICG-enhanced lymphatic vessels intraoperatively before transecting the vessels during LVA. The imaging findings of the lymphatic vessels in laser tomography were investigated. Time required for scanning of the lymphatic vessels was compared between laser tomography and ultrasonography. The correlation between the thickness of the lymphatic vessel wall measured with laser tomographic imaging and the histologically measured thickness of the lymphatic vessel wall was examined. The patency of anastomosis sites was determined based on the image using laser tomography immediately after establishment of LVA. Results A total of 132 ICG-enhanced lymphatic vessels were scanned with laser tomography showing clear lumen with surrounding vessel wall. The required time for lymphatic vessel scanning was significantly shorter with laser tomography than with ultrasonography (1.6 ± 0.3 vs. 4.8 ± 1.2 minutes; p = 0.016). Strong correlation was seen between the thickness of the lymphatic vessels wall measured using laser tomography and the histologically measured thickness of the lymphatic vessel wall (r = 0.977, 95% confidence interval: 0.897–0.992, p < 0.001). The quality of patency was evaluated immediately after anastomosis, which assisted in deciding whether reanastomosis was needed. Conclusion Microscope-integrated laser tomography provides real-time images of the lymphatic vessels in extremely high resolution and enables evaluation of lymphatic lumen condition and objective post-LVA anastomosis status.

The aim of this article is to make a multi-criteria analysis of various exhibition spaces of an originally non-exhibition character and to determine how these spaces affect the selection of works and the exhibition concept. The analysis is based on the exhibitions of art objects at collective exhibitions in unconventional architectural spaces: commercial, i.e. the modern office building of PBG Gallery Skalar Office Centre in Poznań, post-industrial i.e. in the former Zakłady Przemysłu Ziemniaczanego Lubanta S.A. and in the historic interior of the "U Jezuit&oacute;w" Gallery of the Cultural Integration Centre in Poznań. The multi-criteria comparative analysis shows a variety of features of the studied spaces as well as the relationship between architecture and art and their mutual interaction. The participatory role of the non-exhibition space in the process of creating an exhibition and selecting works has been proven. It has also been confirmed that the presentation of works of art in originally non-exhibition spaces creates a new quality of the artwork. Unconventional architectural space, when used for the exhibition of works of art, expands and strengthens the area of ​​their influence through the interaction between the work and the architectural space. The specificity of the space adapted for exhibition needs, the presence and type of architectural details in the interior, the quantity and quality of light and its distribution in space, the volume and colour of the interior determine the exhibition space and influence the shape of the exhibitions organised and the reception of the artworks. The only condition for the change of the original function of an architectural space into that of an exhibition space is a coherent artistic vision of the creator. This should take into account the appropriate selection of the exhibited objects, where the process of searching for the relationship between architecture and art determines the features of the architectural space as integral components influencing the realisation of the exhibition .

Purpose This study presents a comparative analysis of water quality data in an urban micro watershed to study the magnitude of impacts on the water quality parameters over the last decade. The purpose of this paper is to evaluate the degree of deterioration using the water quality index. Design/methodology/approach Rapid urban growth without proper land use and occupation planning results in the overload of urban water resources. Therefore, a literature review was conducted on the research subject published in the dissertation databases of the Engineering Faculty of Ilha Solteira, which resulted in the selection of two dissertations on water quality in the Ipê Stream, Ilha Solteira – SP, Brazil. The results will be evaluated according to the Brazilian laws and regulations in force. Findings This study shows that pollution and degradation in the stream intensified during the study period, with the most impacted areas within the urban perimeter. Practical implications The increasing impacts underscore the need for efficient measures such as implementation of retention reservoirs, elimination of clandestine sewage connections and restoration of riparian forests. Originality/value This study highlights the need to monitor the water quality of streams in order to establish preventive and mitigating measures to avert the growing environmental impacts and to ensure quality water for future generations.
