In public procurement, most contracts are renegotiated ex post and involve subcontractors. We examine whether there is a causal link between subcontractor use and the incidence of change orders to amend the original scope of a project. Since subcontracting is likely related to unobserved project complexity, we use a novel IV, the predicted level of subcontracting from a method modeled after Christakis et al. (2010), to estimate the likelihood of renegotiation. The results establish that subcontractors are associated with an increased likelihood of change orders as well as a higher dollar amount renegotiated.  相似文献

The relationship between moving home, family structure and children's well‐being, is examined in the National Child Development Study (NCDS) Second‐Generation. Well‐being is measured as attainment in maths and reading, and on two behavioural assessments. Multivariate multi‐level modelling allows for heterogeneity both within and between families. We find little to no association between moving home and children's well‐being. Associations between family living arrangements and children's development appear to be mediated by human, financial and social capital, but not, on average, worsened by geographical mobility.

The international long-term care (LTC) debate has recently been focusing on how to strengthen home care provision. In this regard, a major role has been played by informal care and how to best integrate it in a holistic care approach. Italy and Spain, usually labeled as “familialist” or “family-based” care models, have been promoting national reforms or actions to support the integration of “informal” actors into the overall LTC system. Through a comparative review of recent trends observed in the two care regimes, this article aims at contributing to improve our cross-national understanding of how LTC is changing across Europe, identifying the basic approaches adopted in Italy and Spain and highlighting both their strengths and drawbacks.  相似文献

We evaluate men's retrospective fertility histories from the British Household Panel Survey and the U.S. Panel Study of Income Dynamics (PSID). Further, we analyze the PSID men's panel-updated fertility histories for their possible superiority over retrospective collection. One third to one half of men's nonmarital births and births within previous marriages are missed in estimates from retrospective histories. Differential survey underrepresentation of previously married men compared with previously married women accounts for a substantial proportion of the deficits in previous-marriage fertility. More recent retrospective histories and panel-updated fertility histories improve reporting completeness, primarily by reducing the proportion of marital births from unions that are no longer intact at the survey date.  相似文献

This paper reviews divorce‐related parenting programmes, assessing the extent to which fathers are included and whether father inclusion influences outcomes. The paper also discusses limitations of the research evidence and implications for future intervention and evaluation design. Thirteen programmes met the criteria in the review period 2005–2012 but only four had been evaluated using randomized control trials or with independent measures from mothers and fathers. Analysis of these four programmes shows modest evidence of reduced couple‐conflict, improved coparenting and some evidence of improved child outcomes. Key issues raised are the need for improving the quantity and quality of demographic data about fathers; the importance of incorporating analysis by gender of parent into evaluation design and the value of developing and routinely using father‐related indicators to measure programme impact on men's parenting, fathering and co‐parental relationships.  相似文献

A number of U.S. State Departments of Transportation have adopted a price adjustment policy designed to limit cost fluctuations of oil‐based inputs in government procurement. Similar policies are common in defense contracting, and have been used to offset financial losses of health insurance companies in Medicare and the Affordable Care Act. We show that while all bidders submit lower bids after the policy is introduced, the extent of bid reduction diminishes with firm size. Small new firms are able to compete more frequently, promoting auction competition and efficiency. (JEL H4, H57, D44)  相似文献

Although there are a number of highly efficacious in‐person treatments designed to ameliorate relationship distress, only a small proportion of distressed couples seek out in‐person treatment. Recently developed internet‐based interventions based on these in‐person treatments are a promising way to circumvent common barriers to in‐person treatment and give more distressed couples access to these efficacious interventions. The overarching aims of this review are to provide couple and family therapists with a broad overview of the available internet‐based interventions and provide suggestions about how these interventions might be utilized before, during, or after in‐person treatment. The majority of the review centres on internet‐based interventions for distressed couples and covers four distinct types of resources: relationship advice websites; assessment/feedback interventions; enrichment interventions for satisfied couples; and interventions targeting at‐risk or distressed couples. Included is a case study of one couple's journey through a newly developed intervention targeting at‐risk couples, OurRelationship.com . Internet‐based interventions targeting individual psychopathology (e.g. anxiety and depression) are also reviewed. These interventions would be particularly useful as an adjunctive resource for in‐person couple or family therapy when referrals for a concurrent in‐person individual therapist are not feasible (because of time, financial, or geographic constraints). We close with three appendices: two appendices with information on currently available internet‐based interventions; and one appendix with recommendations on how to incorporate these resources into in‐person therapy.  相似文献

Objectives: To conduct an 8-year follow-up of the National Elder Mistreatment Study (NEMS) and specify risk ratios for negative outcomes of elder abuse, including DSM-5 defined depression, generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD), and poor self-reported health.

Methods: Attempts were made to re-contact, via Computer Assisted Telephone Interview, all 752 NEMS participants who reported mistreatment since age 60 at Wave I, as well as a randomly selected sample of non-mistreated NEMS participants

Results: 183 NEMS Wave I elder abuse victims and 591 non-victims provided data. In bivariate analyses, elder mistreatment 8 years earlier increased risk of negative outcomes by 200–700%. However, multivariate analyses revealed that Current (Wave II) social support was highly protective against most negative outcomes (excepting PTSD), and even appeared to nullify effects of mistreatment on GAD and poor self-reported health.

Conclusions: Outcomes of elder mistreatment have not been studied prospectively in a national sample. The NEMS 8-year follow-up findings indicate a strong relationship between elder mistreatment at Wave I and negative emotional and physical health 8 years later. Fortunately, current (Wave II) social support appears to be both consistently and powerfully protective against most negative outcomes.  相似文献

Intercultural understanding (ICU) is becoming an essential part of living and contributing effectively in our increasingly diverse society. In fact, ICU is a key capability in the Australian schooling curriculum, alongside other general capabilities such as numeracy and literacy. While there are current instruments assessing ICU, there is little evidence-based research surrounding their use in primary and secondary school settings. In the context of a larger project, this study outlines the development and validation of a new ICU instrument specifically for use in primary and secondary schools. Among a sample of teachers and students from 12 Australian primary and secondary schools, the study found a teacher ICU instrument with a four-factor structure and a student ICU instrument with a two-factor structure. Further research and implications are discussed.  相似文献
