General optimization model for the energy planning of industries including renewable energy: A case study on oil sands

A multi‐period optimization model is developed for the energy procurement planning of industries including renewable energy. The model is developed with the objective of identifying the optimal set of energy supply technologies to satisfy a set of demands (e.g., power, heat, hydrogen, etc.) and emission targets at minimum cost. Time dependent parameters are incorporated in the model formulation, including demands, fuel prices, emission targets, carbon tax, lead time, etc. The model is applied to a case study based on the oil sands operations over the planning period 2015–2050. Various production alternatives were incorporated, including renewable, nuclear, conventional and gasification of alternative fuels. The results obtained indicated that the energy optimization model is a practical tool that can be utilized for identifying the key parameters that affect the operations of energy‐intensive industrial operations, and can further assist in the planning and scheduling of the energy for these industries. © 2016 American Institute of Chemical Engineers AIChE J, 63: 610–638, 2017     

建筑物维修管理系统数据库的设计

为了保证物业管理中建筑物维修管理工作的有序进行，本文根据数据库的设计原理、方法，结合建筑物维修管理的实际应用环境和操作业务流程，提出了建筑物维修管理系统数据库设计的4个阶段——用户实际需求分析、概念结构设计、逻辑结构设计和物理结构设计，设计出适用于各种建筑物维修管理系统的最优数据库模式，并建立了通用的数据库应用系统，使得维修管理系统能够进行建筑物损坏情况的综合评价和维修决策。     

繁荣与颓废

从建筑的发包商到建筑商，从方案的设计者到监理者，从项目的决策者到消费者，他们对建筑和城市的美与丑都负有直接的责任。外在酷似繁荣的城市，内部包容了多少的颓废，他们人性的弱点通过建筑项目的流程得到淋漓尽致的发挥。兴叹胜于欣慰，劝诫不如自省。还是警钟长鸣，从己做起。     

Adapting cognitive-behavioral therapy for Mexican American students with anxiety disorders: Recommendations for school psychologists.

Mexican American students are the fastest growing group in U.S. public schools. There is a growing body of research indicating that Mexican American families underutilize mental health services and are more likely to drop out of care prematurely when they do seek help. These findings may indicate that our health care system is not providing ethnic minorities with culturally competent care. Although cognitive?behavioral interventions are considered to be evidence-based treatments for child anxiety disorders, previous protocols have not taken cultural factors into account. This article discusses how to adapt cognitive?behavioral therapy (CBT) for Mexican American students with anxiety disorders. Working within the Psychotherapy Adaptation and Modification Framework (PAMF), this article offers adaptation principles that may guide school psychologists in implementing CBT strategies when working with Mexican American youth and their families. A case study is provided illustrating how cultural modifications of CBT can lead to positive outcomes for Mexican American students. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

使用成本管理:与消费者一起创造利润

成本利润分析在企业经营中占有中心地位,这是因为企业每项经营管理活动都需要比较其成本与受益,但是,目前企业经营活动中,更多地考虑了产品生产过程中的制造成本和打入市场的销售成本,而忽视了站在消费者的角度考虑使用成本.随着市场竞争的日趋激烈,商品的使用成本在企业经营决策中的作用已经越来越重要.因为消费者购买的不是商品本身,而是商品满足需要的某种性能.     

Modelling the Roles of Cewebrity Trust and Platform Trust in Consumers’ Propensity of Live-Streaming: An Extended TAM Method

Live streaming is a booming industry in China, involving an increasing number of Internet users. Previous studies show that trust is a cornerstone to develop e-commerce. Trust in the streaming industry is different from that of other e-commerce areas. There are two major dimensions of trust in the live streaming context: platform trust and cewebrity trust, which are both important for customers to adopt and reuse a specific live streaming service. We collected questionnaire data from 520 participates who have used live streaming services in China. We model the collected data and identified factors that can influence users’ propensity by an extended technology acceptance model (TAM) method. According to our analysis, both cewebrity trust and platform trust will greatly influence users’ intention to reuse a certain platform. Moreover, results also indicate that cewebrity trust is far more important than platform trust. These findings can lead to several management strategies to improve the adherence of users to streaming platforms.     

Characterization of red wines from South America based on sensory properties and antioxidant activity

BACKGROUND: It is widely accepted that red wines constitute one of the most important sources of dietary polyphenolic antioxidants. However, it is still not known how some variables such as variety, vintage, country of origin, and retail price are associated with the antioxidant activity and sensory profile of South American red wines. In this regard, 80 samples produced in Brazil, Chile and Argentina were assessed in relation to their sensory properties, color and in vitro antioxidant activity, and results were subjected to multivariate statistical techniques. RESULTS: Samples were grouped in clusters, characterized by high, intermediate and low in vitro antioxidant activity, sensory properties and prices. It was possible to observe that wines with high antioxidant activity were associated to high retail prices and overall perception of sensory quality. CONCLUSION: South American wines produced from Vitis vinifera such as Syrah, Malbec and Cabernet Sauvignon had higher in vitro antioxidant activity and also higher sensory quality than wines produced from Vitis labrusca. This result was independent of vintage (2002‐2010), corroborating the idea that the same grape varietal, even when produced in different years, displays similar sensory characteristics and antioxidant activity.
