Consensus on Quality Indicators for Pediatric Oncology Nursing Care in Mainland China: A Delphi Method and Analytic Hierarchy Process

Background: Because routine nursing quality indicators are not suitable to evaluate pediatric oncology nursing care, this study aimed to identify a set of quality indicators for pediatric oncology nursing care in mainland China. Method: This prospective investigation utilized a modified Delphi technique and an analytic hierarchy process. A survey questionnaire was developed using a literature review and semi-structured interviews. Fifteen invited experts evaluated the importance of potential indicators through three rounds of Delphi survey by email in 2018. The importance weight of each indicator was identified through analytic hierarchy process. Results: In the Delphi survey, the average authoritative coefficient was 0.93–0.96 for each round of the inquiry. After three rounds of survey, 29 quality indicators were identified as important nursing outcomes for assessing the quality of pediatric oncology nursing care in mainland China. The importance rating mean score of indicators ranged between 4.67–5.00 on a 5-point scale, and the variation coefficient ranged between 0–0.19. Expert-assigned indicator importance weight varied between 0.0040–0.0870. Conclusion: This study identified an indicator system with 29 nursing-sensitive quality indicators that may represent potential indicator candidates for quality assessment of pediatric oncology nursing practice in mainland China.

Functional-cost analysis of methods of regeneration of used mineral motor oils

The main methods of regeneration of used mineral motor oils, in particular physical, chemical, physicochemical methods are considered. The functional-cost analysis of methods of regeneration of the used mineral motor oils by means of branch experts is carried out. Functional-cost analysis is a method of pairwise comparisons and involves the process of ranking the selected characteristics according to the degree of importance (weight). To do this, each characteristic is assigned a certain index. As a result of the functional-cost analysis, the expediency of using technologies of vacuum distillation and hydrocracking of used oils in the processes of regeneration of used oils has been established.

Self-Adaptive Priority Correction for Prioritized Experience Replay

Deep Reinforcement Learning (DRL) is a promising approach for general artificial intelligence. However, most DRL methods suffer from the problem of data inefficiency. To alleviate this problem, DeepMind proposed Prioritized Experience Replay (PER). Though PER improves data utilization, the priorities of most samples in its Experience Memory (EM) are out of date, as only the priorities of a small part of the data are updated while the Q network parameters are updated. Consequently, the difference between storage and real priority distributions gradually increases, which will introduce bias into the gradients of Deep Q-Learning (DQL) and make the DQL update toward a non-ideal direction. In this work, we propose a novel self-adaptive priority correction algorithm named Importance-PER (Imp-PER) to fix the update deviation. Specifically, we predict the sum of real Temporal-Difference error (TD-error) of all data in EM. Data are corrected by an importance weight, which is estimated by the predicted sum and the real TD-error calculated by the latest agent. To control the unbounded importance weight, we use truncated importance sampling with a self-adaptive truncation threshold. The conducted experiments on various games of Atari 2600 with Double Deep Q-Network and MuJoCo with Deep Deterministic Policy Gradient demonstrate that Imp-PER improves the data utilization and final policy quality on discrete states and continuous states tasks without increasing the computational cost.

Use of Multicriteria Analysis Method DEXi to Define Priorities in Implementation of Irrigation Plans

Methodology for determining priorities in implementing irrigation plans using multicriteria analysis method DEXi is applied on the specific case study area in the sub-catchment area of river Orljava in Požega-Slavonia County, Croatia. Five potential irrigation areas are analyzed according to five selected criteria: environmental protection, water-related (4 sub-criteria), social, economic and time criteria with different criteria importance (weight). The aims of this paper are: confirm the adequacy of using DEXi method when determining priorities in fulfilling irrigation plans; present the model for preparation of the input data; apply the method and give feedback on the application.

An Empirical Analysis of the Joint Effects of Shoppers’ Goals and Attribute Display on Shoppers’ Evaluations

This article develops a decision-making framework that highlights how display of numeric attribute information (e.g., display of calorie information) and shoppers’ goals (i.e., having a diet focus vs. a taste focus) jointly influence shoppers’ choices and preferences. Across two sets of studies, including a field study involving the launch of a new Coca-Cola product, the authors show that when food items are displayed in an aligned manner (i.e., when food items with lower-value calorie information are displayed below food items with higher calorie values), shoppers assign more importance weight to calorie gap information. In turn, higher importance weight assigned to calorie gap information leads diet-focused shoppers to relatively prefer low-calorie food items but leads taste-focused shoppers to relatively prefer higher-calorie food items. The third set of studies shows that this decision-making framework has widespread applicability and is relevant in any domain in which advertising, retail, and online displays show comparisons of numeric attribute information.

ANALYSIS OF THE CONSUMERS PREFERENCES OF LIPSTICK PRODUCT AND ITS RELATIONSHIP WITH THE SEGMENTATION OF THE LIPSTICK PRODUCTS

The need for lipstick continues to increase along with the emergence of a new lipstick products both domestic and global brands to follow the needs of its consumers, the new product has a variety of functions other than just as a lip color, but also as a moisturizer / lip protection even as treatment. Adult lipstick is packed with advertisements and packaging are very interesting addition to the color choice of more and more. In determining the selection of lipstick products consumers often consider the combination of the main attributes and other factors that are trade-offs. This study aims to determine the attributes and combination of attributes among the most preferred by consumers for a segment of the age and the amount of income. Sources of data in this study were obtained from 138 respondents in the city of Bogor and its surroundings, conjoint analysis is used to determine the usefulness of each attribute and their relative weights as a tool to predict the preferences of a particular segment or as a whole. The results showed the order of importance weight according to the respondents is that the quality attributes (34.95%), the type of color (33.21%) and benefits (31.84%), while the combination of the most preferred products are: lipstick durable / waterproof, according to skin color, and functioning for moisturizing / protective lip. In the description also delivered conjoin analysis results for each age and income segments.
