Abstract

In an economic climate when colleges can no longer presume that legislators see institutions of higher learning as tacit public goods, institutions around the country are facing budget cuts. This article presents a case study of the experience of a mid-sized public state university and its Library in a budget crisis undergoing a university-wide program prioritization process. The authors review the process of writing three reports on the Library’s value, along with the approach to engaging staff in the process including a retreat. This article raises questions about what every library should consider assessing and provide tools for libraries navigating similar terrain.  相似文献

Chaos theory, informational needs, and natural disasters   总被引:2,自引:0,他引:2  
This study applies chaos theory to a system-wide analysis of crisis communication in a natural disaster. Specifically, we analyze crisis communication during the 1997 Red River Valley flood in Minnesota and North Dakota. This flood, among the worst in modern American history, consumed entire metropolitan areas, displacing thousands of people. The conditions and decisions leading to the disaster, and the subsequent reactions are retraced. Communication related to river crest predictions (fractals), the shock at the magnitude of the crisis (cosmology episode), novel forms of reorganizing (self-organization), and agencies that aided in establishing a renewed order (strange attractors) are evaluated. Ultimately, we argue that preexisting sensemaking structures favoring rationalized, traditional views of a complex system led officials to make inappropriately unequivocal predictions and ultimately diminished the effectiveness of the region's crisis communication and planning.  相似文献

The objectives of the study were to assess the prevalence of child sexual abuse (CSA) in a nation-wide representative sample of 14–17 year old Israeli adolescents, and to examine the associations between CSA, socio-demographic correlates and various measures of physical and mental health. The study population consisted of 906 mother–adolescent dyads, belonging to a community based, representative sample of Israeli 14–17 year olds, interviewed in 2004–5. Response rate was 68%. Subjects provided demographic data, and information about CSA, physical symptoms, body image, well-being and use of mental health services. DAWBA was used to obtain information regarding mental disorders and suicidality. SDQ was used to obtain data on bullying. Statistical analyses were conducted using an SPSS-17 complex sample analysis module and multivariate analyses were conducted to assess the associations between CSA and risk factors and social and health related correlates. Findings show that CSA was reported by 3.3% of adolescents. Higher risk of exposure to CSA was found among girls, among adolescents living in a one-parent household and among adolescents with a chronic disability. In multivariate models adjusting for gender, learning disabilities and depression, CSA was associated with suicidal attempts, stomach ache, dizziness, sleep problems, well being at home and bullying behaviors. No association was found with suicidal ideation or other physical symptoms. Our findings confirm that the associations between CSA and different outcomes vary depending on the socio-psychological context, and underline the importance of addressing the complexity of variables associated with CSA.  相似文献

The aim of this study was to investigate the frequency of child physical maltreatment (CPM) in children with autism aged 2–5 years in Henan province (China), and to explore the risk factors for severe CPM in these children. This cross-sectional study was performed at the Psychology Clinic of the Third Affiliated Hospital of Zhengzhou University between September 2012 and September 2013 with 180 parents of children with autism. Children and parents had no history of any cognitive therapy. The childhood autism rating scale (CARS) was used to evaluate the severity of autism in children. Data on parental CPM during the past 3 months were collected from parental self-reporting. Logistic regression was used to investigate the risk factors of severe CPM. CPM was self-reported by 88% of the parents of children with autism. One hundred and fifty four of these cases were in the minor CPM group (86%) and 64 in the severe CPM group (36%). Most cases of severe CPM were unlikely to have caused injury. Univariate analyses showed that child's age (p = .018), age started to speak (p = .043) and CARS score (p = .048) were associated with severe CPM. Child's age (p = .011) and CARS score (p = .041) were independently associated with severe CPM. The risk of severe CPM increased with age and CARS score. Our findings showed that CPM is widespread in families of children with autism in Central China and more knowledge should be provided to parents of children with autism, particularly in cases of severe autism (those with high CARS scores).  相似文献

Decisions about preservation issues are made both deliberatively and unconsciously. Heuristics operate as intuitive processes which are rapid and can be reliable and effective. Deliberative decisions require time to complete and can be described by an analytic-deliberative model. The characteristics of these two processes and their relevance to preventive conservation decision-making are discussed. Each of these two processes has its strengths and weaknesses. People naturally make decisions and utilise a range of strategies without necessarily having insights into the process. This paper provides a frame to help examine, describe, and reflect upon our own and others’ decision-making in order to improve both processes and outcomes.  相似文献

20世纪50年代以来,随着风险管理这一新兴管理学科的迅猛发展,其走入教学范畴是自然而然的事情。教学风险是指教学的实际结果与预期结果间的偏差。导致或加剧教学的实际结果与其预期结果之间的偏差的原因或条件,被称为教学风险的风险因素。依据不同的分类标准,可以对教学风险进行不同的分类。当前我国应加强对教学风险的研究与应对工作。  相似文献
