Growing concern about the degradation of the environment and public health has called into question the use of conventional household batteries that are consumed and then typically discarded. Because most conventional batteries are not recycled, they end up in landfills where they decompose, potentially leaching harmful chemicals into the surrounding soil. Bio‐based batteries, which are made from agricultural by‐products, have been designed to help meet the need for household batteries while using sustainable, safe technology. This research examines the links between consumer willingness‐to‐pay (WTP) for bio‐based batteries and consumer characteristics and preferences for certain product attributes and environmentally‐friendly practices. We designed a nationwide survey and analyzed the survey data using the dichotomous‐choice contingent valuation method. The results show an increase in the estimated WTP in the Midwest and South in response to an information treatment about bio‐based batteries. Overall, U.S. consumers concerned about green production and recycling practices are willing to pay a premium for bio‐based batteries. Our results provide essential information for quantitatively assessing the potential market impact of bio‐based batteries, for developing effective management and marketing strategies to reach various consumer groups, and for efficiently establishing sustainable policies and regulations. 相似文献

The disproportionate representation of minority students in special education has been a concern for decades. The Individuals with Disabilities Education Act mandates states to have policies and procedures in place to prevent inappropriate over identification or disproportionate representation by race and ethnicity of students with disabilities. The purpose of this study was to investigate the current status of minority representation in special education given the mandate and related efforts to reduce overrepresentation and to identify trends for the 5-year period from 2004 to 2008. Growth models were used to analyze trends in national data collected from the 50 states and the District of Columbia for these 5 years. Findings indicate some improvements from 10 years ago, especially noteworthy are a significant decrease in the number of African American students and a moderate decrease in the number of Hispanic students categorized as having intellectual disabilities. However, during the same period, the number of Hispanic students in learning disabilities increased. Otherwise, the trend of racial/ethnic representation in special education remains the same as it was a decade ago. 相似文献

Effect of Acceptance Expectations on the Employment Development of Individuals With Disabilities: The Self‐Fulfilling Prophecy Applied 下载免费PDF全文
Li Ju Chen 《Journal of Employment Counseling》2015,52(3):98-109
The author examined what and how factors affect the employment status of Taiwanese college students with disabilities in the 1st year after graduation. The results demonstrated that (a) perceived acceptance by society and the employment market (ASEM) was the major factor affecting the employment status of individuals with disabilities (IWDs); (b) perceived ASEM influenced IWDs' psychological states, attitudes, and life‐planning styles, as well as their attitudes and strategies in job searching; and (c) the effect of IWDs' acceptance expectations on their employment development can be explained by the self‐fulfilling prophecy. 相似文献

As postindustrial societies become more dependent on technology, they also become encumbered by greater risk. With the mounting news reports of cyberattacks, a common reaction to these technology‐based hazards is anxiety. Whether anxiety enhances or erodes information processing is a topic of debate in previous literature, and equally uncertain is whether mass anxiety facilitates or hobbles the public's ability to contemplate current events. In light of three theoretical models in the basic research of anxiety, we hypothesized that (1) anxious participants are less able to recall the information in a news report of cyberattack than their nonanxious counterparts, (2) they become increasingly inept at recalling the details as the storyline unfolds, and (3) this impairment is unique to anxiety. Participants in Study 1 (130 college students) and Study 2 (392 American adults) viewed a news story of a cyberattack and then reported their emotional states and their levels of understanding of the various parts of the report—except that the anxiety in Study 1 was naturalistic, and in Study 2, experimentally manipulated. Results from both studies showed that anxiety undermined recall performance. In addition, Study 1 found that the recall was worse towards the middle and the end of the news story and that other emotions were not significantly associated with memory deficit. Anxiety is discussed as a barrier for the public to stay informed about cyberattacks. 相似文献

人际环是以水平轴亲和维度和垂直轴控制维度为核心,按照规定序列排列在一个环形的空间。研究目的:研究融合人际互动与人格特质两个心理学研究领域,探讨中国文化下人际互动中人际环状结构。研究方法:本研究以人际环为理论基础,设计三种不同关系类型:夫妻关系、同性好友关系和恋人关系,采用多元变量分析和随机化测验方法检验本土文化下人际互动中个体的人际特质结构。研究结果:显示互动中个体人际特质以两个基本维度(亲和维和控制维)为核心,这两个维度体现出人际关系互动中的两个重要信息:地位和爱。人际特质包含六个因子,分别是人际冷漠性、人际亲和性、人际开放性、人际退缩性、社会支配性和社会服从性。此六因子以水平轴亲和维度和垂直轴控制维度为核心,形成一个不规则的六边环形,并以规定序列排列成环形空间。 相似文献
