Public–Private Partnerships (PPPs) have become a critical vehicle for delivering infrastructure worldwide. Yet, the use of such a procurement strategy has received considerable criticism, as they have been prone to experiencing time/cost overruns and during their operation poorly managed. A key issue contributing to the poor performance of PPPs is the paucity of an effective and comprehensive performance measurement system. There has been a tendency for the performance of PPPs to be measured based on their ex-post criteria of time, cost and quality. Such criteria do not accommodate the complexities and lifecycle of an asset. In addressing this problem, the methodology of sequential triangulation is used to develop and examine the effectiveness of a ‘Process Management Life Cycle Performance Measurement System’. The research provides public authorities and private-sector entities embarking on PPPs with a robust mechanism to effectively measure, control and manage their projects’ life cycle performances, ensuring the assets are ‘future proofed’.  相似文献

Abstract

Based on the value of children theory, the purpose of this study was to develop and establish the factor structure and internal consistency reliability of the Advantages of Children Scale (ACS), a self-report measure of a modification of Hoffman and Hoffman’s value scheme of the psychological needs children meet for their parents. Data were collected from 685 emerging adult men identifying as Latino or Caucasian who were not parents. Results of the confirmatory factor analysis found a good fit for the six hypothesized subscales on the ACS: connectedness, expansion of self, family heritage, adult status and social identity, development of self, and family maintenance. We discuss potential applications of the measure in research and practice.  相似文献

Major accident risks posed by chemical hazards have raised major social concerns in today's China. Land‐use planning has been adopted by many countries as one of the essential elements for accident prevention. This article aims at proposing a method to assess major accident risks to support land‐use planning in the vicinity of chemical installations. This method is based on the definition of risk by the Accidental Risk Assessment Methodology for IndustrieS (ARAMIS) project and it is an expansion application of severity and vulnerability assessment tools. The severity and vulnerability indexes from the ARAMIS methodology are employed to assess both the severity and vulnerability levels, respectively. A risk matrix is devised to support risk ranking and compatibility checking. The method consists of four main steps and is presented in geographical information‐system‐based maps. As an illustration, the proposed method is applied in Dagushan Peninsula, China. The case study indicated that the method could not only aid risk regulations on existing land‐use planning, but also support future land‐use planning by offering alternatives or influencing the plans at the development stage, and thus further enhance the roles and influence of land‐use planning in the accident prevention activities in China.  相似文献

ABSTRACT

The importance of compassion in healthcare is universally acknowledged. However, the factors that enhance compassion are not well understood. The perception of common humanity has been proposed as a prosocial perspective that leads to unbiased universal compassion. There has been a lack of research into the relationship between common humanity and compassion. This study examined the use of common humanity scenarios to promote compassion in healthcare workers. Seventy-five healthcare workers were randomly assigned to two groups and shown a different common humanity scenario. The healthcare workers were asked what effect viewing the videos had on their perception of common humanity and compassion. Thematic analysis was used to identify themes. Four main themes emerged: (a) common bonds; (b) people have the same needs; (c) no one wants to suffer; (d) seeing strangers helping others is motivating. Healthcare workers reported feelings of care, concern, and compassion after viewing common humanity scenarios.

IMPLICATIONS
  • Viewing common humanity scenarios appears to lead to enhanced feelings of connection to others and compassion in healthcare workers.

  • Using common humanity scenarios may be a useful compassion training strategy in healthcare.

  • Further research is necessary to gain a better understanding of how viewing common humanity material influences compassion.

Using family stress theory, this study examined the relationship between adolescent reports of selected demographic variables (gender, age, family form), interparental conflict (style, content, intensity, resolution), stress due to the pileup of stressors, coping strategies (social support, detrimental coping), and adolescent family life satisfaction. The sample was comprised of 155 adolescents ranging from 14 to 18 years of age who completed self-report questionnaires at one of three rural Oklahoma high schools. Four dimensions of interparental conflict (overt conflict style, conflict about childrearing, conflict about family roles/finances, conflict resolution), stress due to pileup, social support coping, and detrimental coping were significantly related to family life satisfaction. Adolescent age was positively related to family life satisfaction. Within the scope of family stress theory, scholars have addressed how the combination of stressors and coping strategies relates to the adaptation of individuals within family systems (McCubbin and Patterson 1983). Further, investigations of the relationship of parental divorce to well-being in children and adolescents suggest that interaction patterns within various family forms may be more fruitful in explaining the adaptation of youth than parental marital status (Demo 1992). The perception by youth of conflict between their parents (i.e., interparental conflict) has emerged as a key family stressor that has the potential to explain variation in adolescent adaptation in a variety of family forms (Buehler, Krishnakumar, Anthony, Tittsworth, and Stone 1994). Stressor events for adolescents such as interparental conflict generally do not occur in isolation. Rather, they exist within the context of other stressors such as economic stress, difficulties at school, or normative developmental tasks for families with adolescents (e.g., changing family roles to allow greater adolescent autonomy; McCubbin and Patterson 1986). Further, considerable variation exists in the coping strategies (e.g., social support, avoidance) that adolescents use in response to stress (McCubbin and Patterson 1986). Finally, previous research shows variation between certain demographic variables and adolescent adaptation. Thus, the current study was developed to examine how selected demographic variables (gender, age, family form), adolescent perceptions of interparental conflict (style, content, intensity, degree of resolution), stress based on the pileup of stressor events, and coping strategies relate to adolescent satisfaction with family life (one indicator of adaptation).  相似文献

Many Australians are requiring mental health care, including families, leading to long wait times in order to access support. Walk-in therapy reduces barriers to mental health support services by providing support at the time that families seek help. This paper presents a proof-of-concept study investigating the acceptability and short-term effectiveness of an online walk-in family therapy service, Walk-in Together (WIT). Part 1 of the paper describes the experiences of 44 family members from 22 families who presented to a public family therapy clinic for a virtual walk-in family therapy session. The session was conducted by a team of three experienced family therapists. Family members' experiences were sought pre-session, post-session, and at 6 weeks follow-up via survey and interview. Part 2 of the paper explores therapist perceptions (n = 7) of the WIT approach, through thematic analysis of semi-structured interview data. Post-session feedback showed 85% of family members found WIT to be helpful and 50% were optimistic about their future as a family after their WIT session. Six weeks post-session it was revealed that WIT supported planning for families in equipping them to move forward with 88% of family members reporting that they knew what to do after the session. All therapists uniformly experienced the model as offering a timely and beneficial service, suitable for diverse presentations and constellations of families. These preliminary results suggest the significant utility of this WIT intervention as a well-received and helpful service for families, who valued the easy access and rapid therapeutic response afforded by the online, walk-in delivery model. This proof-of-concept paper suggests the potential for further development and growth of WIT, as well as other mental health support services using a walk-in, telehealth model to meet the rising demand for therapeutic support for families in distress.  相似文献

There are numerous situations where governments take action due to systematic information asymmetries in society, while economics textbooks do not offer an integrated theory to justify these interventions in terms of utility. This paper starts with a taxonomy of situations where governments try to correct for information asymmetries. A distinction is made between government interventions due to information asymmetries between market partners, within political markets and between the government and citizens. It is then shown that Public Choice Theory offers only few and Public Finance Theory not enough explanations for the prevalence of such government interventions. Further explanations for government actions are given by Institutional Economics and Cultural and Behavioural Economics. The latter will probably generate the best progress towards creating better explanations.  相似文献

Growing interest in the environmental aspects of migration is not matched by research on their interrelationships, due partly to the lack of adequate data sets on the two together. Focusing on the microlevel, we describe the data required to effectively investigate these interrelationships. Data sources are discussed, including information that should be collected, focusing on household surveys and remote sensing. The main section of the paper describes three alternative approaches to data collection: (a) using existing population and environmental data from different sources, illustrated by Burkina Faso; (b) adding questions to a survey developed for another purpose, illustrated for Guatemala using a DHS survey; and (c) designing a new survey specifically to collect both migration and environmental data to investigate interrelationships, illustrated by Ecuador. Methods used and summary findings are described, followed by a discussion of their advantages and limitations. We conclude with recommendations as to effective use of each approach as research on migration?Cenvironment linkages moves forward.  相似文献

In this paper I first review the basic tenets of agency theory and theory of managerial capitalism as well as some of the major research in these areas then suggest for areas for future research that go beyond the extant empirical work. First, I suggest that it would be useful to reconsider the basic nature of the agency relationship, taking into account that while equity holders can be considered the principal, the board of directors may be more realistically in need of agent-like controls. Second, the complementary or supplementary nature of the monitoring/incentive alignment relationship has been shown theoretically but the empirical evidence is equivocal and needs future investigation. Third, there has been very limited research on the construct validity of archival measures of the sort used in agency theory. This requires the use of methodologies outside those of the more conventional type used in agency theory (i.e., from economics and finance). Finally, agency theory development would profit greatly by more extensive use of research methods such as laboratory studies and survey methodology and the integration of concepts such as personality and control processes.
