Safety Perception

In recent years, with the increasingly popular and openness of Geoparks, Environmental safety has become a major concern for sustainable geo-tourism. It is therefore necessary to conduct an environmental safety performance evaluation for promoting geo-tourism development. In order to identify and figure out the factors influencing the tourists’ environmental safety perception, an index system was established based on six principles of Crime Prevention Through environment design (CPTED) theory. A Questionnaire was adopted for data collection, and the overall evaluation value and concrete index scores at all levels were obtained via the fuzzy comprehensive analysis and Importance-Performance analysis. Empirical results show that: (1) tourists’ perception of environmental safety performance in Shilin Park from high to low was: image and maintenance, Natural Surveillance, territoriality, Access control, Activity support and target hardening; (2) The sub-factors influencing tourists’ safety perception mostly include electronic monitoring device, Lighting system, Public safety management, Road layout, environmental sanitation; While attention should be paid on the following aspects including park service center, inter-personal surveillance, surrounding environment, unobstructed view, parking lot, Signpost, for they are considered as high-importance items with relatively poor performance. Based on the analysis, three optimization measures were proposed, including optimizing the layout and design of each space, strengthening the deterrent force of the park and maintaining a good environmental image. This research provides useful suggestions for Geopark decision-makers on determining the priority of Geopark spatial planning and management, as well as achieving the optimal allocation of resources to promote the sustainable development of Geopark.

Постановка задачи. Ставится вопрос о необходимости развития методологических подходов градостроительного проектирования на микротерриториальном уровне, направленных на создание комфортной и безопасной среды жизнедеятельности в городах и поселениях. Результаты. Получила развитие методология разработки проектов планировки территории - градостроительной документации элементов планировочной структуры (кварталов, микрорайонов, жилых районов) - на основе разрабатываемой в РААСН парадигмы биосферной совместимости городов и поселений, развивающих человека. Предлагается методика оценки вариантов проектов планировки на основе сравнения четырех блоков индикаторов: экологической безопасности жилых территорий, пространственно-территориальных ресурсов, структурно-планировочной и архитектурной организации территории и обеспеченности городскими функциями. По каждому из этих блоков определен необходимый и достаточный состав индикаторов оценки проектных решений. Показаны перспективы развития количественной оценки проектных решений с использованием принципов парадигмы биосферной совместимости на микротерриториальном уровне. Выводы. Выполненная численная оценка проектных решений жилых кварталов показывает прежде всего социальное с точки зрения предоставления необходимых условий жизнедеятельности и развития человека содержание проектов планировки территории, а также их экологический императив. Statement of the problem. The question is raised about the need to develop methodological approaches to urban planning at the microterritorial level aimed at creating a comfortable and safe environment for life in cities and settlements. Results. The authors propose a methodology development project plan for the area - planning documentation of the town-planning elements of the planning structure (blocks, neighborhoods, residential areas) based on the paradigm developed in RAACS of biosphere compatibility of man-made cities and settlements. The method of evaluating variants of planning projects based on a comparison of four blocks of indicators: environmental safety of residential areas, spatial and territorial resources, structural planning and architectural organization of the territory and provision of urban functions. For each of these blocks, the necessary and sufficient composition of indicators is determined, which are calculated based on the design solutions. The prospects for the development of quantitative evaluation of design solutions using the principles of the biosphere compatibility paradigm at the microterritorial level are shown. Conclusion. The numerical evaluation of the design solutions shows the social content of the territory planning projects and reflects the decisions on the urban environment of the city.

The Moment

Background: Traditionally, children with AML undergo аllo-HSCT with myeloablative conditioning (MAC). It is known that MAC is associated with significant transplant-related morbidity and mortality. Reduced-intensity conditioning (RIC) is used in patients not eligible for conventional conditioning therapy due to poor performance status and severe toxic complications after previous chemotherapy. RIC is a well-established treatment strategy in adult patients with comorbidities. But there is no conclusive evidence to support efficacy of RIC allo-HSCT in children suffering from different malignant diseases including AML. The aim: To compare efficacy of different intensity conditioning regimens in children with high risk (HR) AML (according to AML-BFM protocols 1998 and 2004) and to identify factors which have a prognostic significance for overall survival (OS). Patients and methods: Retrospective analysis was performed in 192 patients (pts) with AML (median age of 10 years (0.5-18 y.o.), who received allo-HSCT at R.M. Gorbacheva Research Institute between 08/2000 and 09/2019. MAC (busulfan- or treosulfan-based) were used in 109 pts: 1st CR - 46 pts (MRD+ n=11), 2nd CR - 18 pts, 3rd CR - 1 pt, relapse - 44 pts. Allo-HSCT with RIC were performed in 83 pts: 1st CR - 32 pts (MRD+ n=13), 2nd CR -19 pts, 3rd CR - 4 pts, relapse -28 pts (p=0,674). RIC consisted of fludarabine (30 mg/m2/d x 5 days) + melphalan (70 mg/m2/d x 2 days) or fludarabine (30 mg/m2/d x 5 days) + busulfan (4 mg/kg/d x 2 days). Indication for RIC allo-HSCT was poor performance status (Lansky/Karnofsky score ≤70%), or organ dysfunction due to previous therapy, or infectious complications at the moment of allo-HSCT. Allo-HSCT from matched related donor was performed in 30 pts (16%), from matched unrelated donor - in 98 pts (51%), haploidentical - in 64 pts (33%) and the donor distribution was not different between groups (p=0,878). Post-transplant Cy was included in GVHD prophylaxis regimens in 102 pts (53%). OS were estimated using Kaplan-Meier curves. Univariate analyses were performed using the log rank test for OS, Grey test for cumulative incidences. Multivariate analyses were performed using the Cox proportional-hazard model. Results: Median follow-up was 5 years for МАС, 4.5 years for RIC. In both groups the median time to neutrophil engraftment >=0,5x109/l was D+16 (range D+8-52). Engraftment was observed in 67 pts (81%) after RIC and 94 pts (86%) after MAC (p=0,231). OS after RIC allo-HSCT in the 1st CR was 76% and after MAC - 68% (p=0,014), in 2nd CR 50% after RIC and 54% after MAC (p=0,058), in advanced disease 14% after RIC and 16% after MAC (p=0,394). The transplant-related mortality rate was 19% after RIC and 22% after MAC (p=0,546). Risk of relapse was 28% after RIC and 26% after MAC (p=0,456). Factors influencing OS after MAC were: 1) Remission status at the moment of allo-HSCT (р=0.001); 2) Presence of aGVHD grade I-II (р=0,005); 3) Relapse or MRD+ status after allo-HSCT (р=0.012); 4) Lansky score >70% (р=0,024). Factors influencing OS after RIC were: 1) Remission status at the moment of allo-HSCT (1st remission) (p=0,001); 2) Lansky score >70% (р=0,004). Conclusion: The effectiveness of RIC and MAC is comparable in children with HR AML, but RIC demonstrated better results in 1st CR. The presence of I-II grade aGVHD had positive effect in MAC. Factors influencing OS in both groups were disease status at the moment of allo-HSCT and performance status before allo-HSCT The use of RIC can be effective in patients, especially those who have undergone allo-HSCT in the 1st remission, while minimizing regimen-related toxicity in children who have undergone previous intensive treatment. Multicenter studies are warranted, especially for patients in the first CR, where long-term complications are of most importance. Disclosures No relevant conflicts of interest to declare.

Micro, Small and Medium Scale Enterprises are considered the engine for growth of any nation. Yet, the performance of these enterprises leaves much to be desired. Scholars have asserted that this poor performance is influenced by numerous factors. The study explores the factors influencing the performance of Micro, Small and Medium Scale Businesses in Borno state, Nigeria. A small sample of MSME owners across Maiduguri metropolitan council were randomly surveyed using a single questionnaire. The content validity of the instrument was assessed by scrutiny and validation from two Professors of Management from the University of Maiduguri to ensure statements are clear and capture what they are intended to measure. The reliability of the instrument was also examined using the Cronbach alpha coefficient to ensure items are consistent in measuring each construct. Data was coded and analyzed with the aid of Statistical package for Social Sciences (SPSS) version 23. Results from the exploratory factor analysis showed infrastructural facilities, government policies, entrepreneurial training and insecurity were principal factors exerting influence on the performance of Micro, Small and Medium Scale Enterprises in Maiduguri.

Precise Knowledge

We propose an approach to portfolio management over a finite time horizon that (i) does not require the precise knowledge of the underlying probability distributions, instead relying on range forecasts for the stock returns, and (ii) allows the fund manager to capture the degree of the investor’s risk aversion through a single, intuitive parameter called the budget of uncertainty. This budget represents the worst-case number of time periods with poor performance that the investor is willing to plan for. An application of this setting is target-date funds for pension fund management. We describe an efficient procedure to compute the dynamic allocation between (riskless) bonds and (riskier) stocks at each time period, and we illustrate the risk-to-time-horizon tradeoff on optimal allocation tables, which can easily be provided to fund participants to help them select their strategy. The proposed approach refines rules implemented by practitioners and provides an intuitive framework to incorporate risk in applications with end of horizon effects. In contrast with existing literature providing robust fund management approaches to mathematically sophisticated finance professionals, our goal is to provide a simple framework for less quantitative fund participants who seek to understand how stock return uncertainty and planned retirement date affect the optimal stock-vs-bond allocation in their portfolio. We extend our procedure to the case when the investor’s wealth is penalized for falling short of performance benchmarks across the time horizon. We also discuss the case where the manager can invest in multiple stocks. Numerical results are provided.

Research Outcome

The significance of safety commitment to improving safety performance and reducing risk is widely accepted and substantive research has been conducted globally in order to improve the safety performance of the construction industry such as: “safety commitment”, “design for safety”, “safety culture”, “safety climate”, “behavior base safety BBS”. Despite the research and improvements that have been made through the years, construction stakeholders are continuously being challenged with occurrences of injury on site. Therefore, this paper aims to identify the factors, which influence of management commitment toward improving safety performance in the construction industry of Nigeria. Data was collected through a questionnaire and analysis was performed using SPSS version 16 software. The results of the study showed that “involvement of workers in the preparation of safety programs for the site” and “appropriate issuance of motivational directives by the top management to enhance safety” significantly impact on the safety performance of construction stakeholders. Thus, the research outcome would be of benefit to top management of construction companies, policy makers and building development approvers.

Multiple environmental pressures, both internal and external to the organization, are examined as factors influencing the administration of health and safety programmes and subsequent accident performance. Data were collected from seven industrial sectors in New Zealand. Those firms with better safety records indicated that the most influential factors shaping their policies included government rules and regulations and demonstrated employee concerns and demands. The quality of the relationship with the union and the locus of enterprise ownership also play a significant role in the effectiveness of health and safety administration.

In traditional classrooms, where students are evaluated on the basis of their actions, poor performance is closely linked to the lack of ability. Many students often see failure as a threat to their positive self-image and instead of increasing efforts, apply various ego-protective strategies to shift attention from real or hypothesized lack of ability to other factors influencing unsatisfactory production. In both cases self-worth is protected. This paper aims at performing a motivational analysis of two such strategies, i.e. self-handicapping and defensive pessimism used by secondary school students in achievement context.
