Application of system dynamics for assessment of sustainable performance of construction projects

INTRODUCTION Sustainable development is commonly definedas meeting the needs of the present without compro-mising the ability of future generations to meet theirown needs (WCED, 1987). All industries, includingthe construction industry should contribute to themission. Compared to other industries, constructionactivities are generally considered to have more im-pact on the environment, which provides the basicconditions for the sustainability and development oflife on the Earth.

Two-stage screening for math problem-solving difficulty using dynamic assessment of algebraic learning

The purpose of this study was to explore the utility of a dynamic assessment (DA) of algebraic learning in predicting third graders' development of mathematics word-problem difficulty. In the fall, 122 third-grade students were assessed on a test of math word-problem skill and DA of algebraic learning. In the spring, they were assessed on word-problem performance. Logistic regression was conducted to contrast two models. One relied exclusively on the fall test of math word-problem skill to predict word-problem difficulty on the spring outcome (less than the 25th percentile). The second model relied on a combination of the fall test of math word-problem skill and the fall DA to predict the same outcome. Holding sensitivity at 87.5%, the universal screener alone resulted in a high proportion of false positives, which was practically reduced when DA was included in the prediction model. Findings are discussed in terms of a two-stage process for screening students within a responsiveness-to-intervention prevention model.     

论老舍的文艺美学观

五、六十年代中国的文化生活成了激烈的政治思想斗争的舞台。那时,反对战斗的反人道主义、文化虚无主义、文艺功利主义的人有职业的文艺理论家,诸如巴人、路钥、马寒冰、冯雪样、胡风、钟惦华、陈企霞、陈亚丁及其他许多人。这些文艺工作者公开反对当时的文艺方针,他们的言论受到了经常作为政治责难的严厉批评。除此之外,也有一些作家、演员、艺术家,他们仍法较脚发展真正的社会主义文化的基本理论,他们申的红些人如艾芜、巴金、丁玲、老舍、夏衍、田汉、曹民、沙河等双店负了文艺批评家的重任。这些大作家的文艺批评工作,通常使人感…     

How to deal with emotional abuse and neglect: further development of a conceptual framework (FRAMEA)

Objective

To develop further the understanding of emotional abuse and neglect.

Methods

Building on previous work, this paper describes the further development of a conceptual framework for the recognition and management of emotional abuse and neglect. Training in this framework is currently being evaluated. The paper also briefly reviews more recent work on aspects of the definition, harm caused by emotional abuse and neglect and threshold.

Results

The paper arrives at a working definition as ‘persistent, non-physical, harmful interactions with the child by the caregiver, which include both commission and omission.’ There are many forms of harmful caregiver-child interactions, which can be placed in five categories, each category reflecting the fulfillment of one of the child's basic psycho-social needs and requiring a different therapeutic approach for its alleviation. The caregiver-child relationship is embedded within a psycho-social context. It is suggested that greater clarity can be gained about the child and family when information is sorted into the appropriate tiers of concerns: Tier 0 – Social & environmental factors, Tier I – Caregiver risk factors, Tier II – Caregiver-child interactions and Tier III – Child's functioning. It is further suggested that while intervention is required, this is directed towards protection, rather than providing immediate protection of the child. The work takes the form of a time-limited trial of therapeutic work to gauge the capacity of the caregivers to change. This initial work focuses Tiers 0–II. Statutory steps might be required in order to encourage the caregivers to engage. If insufficient progress is achieved, active child protection may be required which might include placing the child in an alternative family. However, some, usually older, children will remain in the emotionally abusive environment and they will require ongoing help and support.

Conclusion

While a greater understanding of emotional abuse and neglect is now possible, further evaluation of the utility of this framework is suggested.

Impact of a statewide home visiting program to prevent child abuse

OBJECTIVES: To assess the impact of a voluntary, paraprofessional home visiting program in preventing child maltreatment and reducing the multiple, malleable psychosocial risks for maltreatment for which families had been targeted. METHODS: This collaborative, experimental study focused on 6 Healthy Families Alaska (HFAK) programs; 325 families were enrolled in 2000-2001, randomized to intervention and control groups, and interviewed to measure baseline attributes. Follow-up data were collected when children were 2 years old (85% follow-up rate). Outcomes included maltreatment reports, measures of potential maltreatment and parental risks, for example, poor mental health, substance use, and partner violence. HFAK records were reviewed to measure home visiting services. Home visitors were surveyed to measure perceived effectiveness and training adequacy. RESULTS: Parental risks were common at baseline, and one-sixth of families had a substantiated child protective services report in the child's first 2 years of life. There was no overall program effect on maltreatment reports, and most measures of potential maltreatment. Home visited mothers reported using mild forms of physical discipline less often than control mothers. The groups were similar in their use of more severe forms of physical discipline. There was no program impact on parental risks. There was no impact on outcomes for families with a 'high dose' of home visiting. Home visitors often failed to address parental risks and seldom linked families with community resources. Contradictions in the model compromised effectiveness. CONCLUSIONS: The program did not prevent child maltreatment, nor reduce the parental risks that had made families eligible for service. Research is needed to develop and test strategies to improve the effectiveness of home visiting.
