This paper presents a problem structuring methodology to assess real option decisions in the face of unpredictability. Based on principles of robustness analysis and scenario planning, we demonstrate how decision-aiding can facilitate participation in projects setting and achieve effective decision making through the use of real options reasoning. We argue that robustness heuristics developed in earlier studies can be practical proxies for real options performance, hence indicators of efficient flexible planning. The developed framework also highlights how to integrate real options solutions in firms’ strategic plans and operating actions. The use of the methodology in a location decision application is provided for illustration. 相似文献

Decision making theory in general, and mental models in particular, associate judgment and choice. Decision choice follows
probability estimates and errors in choice derive mainly from errors in judgment. In the studies reported here we use the
Monty Hall dilemma to illustrate that judgment and choice do not always go together, and that such a dissociation can lead
to better decision-making. Specifically, we demonstrate that in certain decision problems, exceeding working memory limitations
can actually improve decision choice. We show across four experiments that increasing the number of choice alternatives forces
people to collapse choices together, resulting in better decision-making. While choice performance improves, probability judgments
do not change, thus demonstrating an important dissociation between choice and probability judgments. We propose the Collapsing
Choice Theory (CCT) which explains how working memory capacity, probability estimation, choice alternatives, judgment, and
regret all interact and effect decision quality.

We examined the contribution of relational aggression in adolescents' peer and dating relationships to their psychological and behavioral adjustment. In the Fall and again four months later, 1279 (646 female) grade 9 students reported on relational aggression perpetration and victimization in their romantic and peer relationships, depression/anxiety symptoms (psychological adjustment) and delinquency (behavioral adjustment). Using hierarchical regression analyses, controlling for Time 1 adjustment/behavior, peer relational aggression perpetration predicted depression/anxiety. Dating relational victimization also predicted depression/anxiety, but only for girls. Furthermore, girls who were perpetrators of relational aggression in both peer and dating contexts were most likely to show increases in delinquent behavior. We conclude that dating and peer relationships are not redundant, but make independent and additive contributions to adolescent adjustment. Girls, in particular, may be at greatest risk for poor outcomes when they have relationally aggressive relationships. Results also highlight the need for greater awareness of the complexity and significance of adolescent dating relationships. 相似文献

This study reports preliminary findings regarding the feasibility and efficacy of a novel couple-based treatment, named Strategic Approach Therapy (SAT), for reducing avoidance symptoms of posttraumatic stress disorder (PTSD). Six male Vietnam combat veterans diagnosed with PTSD and their cohabitating marital partners participated in 10 weeks of SAT treatment. Self-report, clinician ratings, and partner ratings of PTSD symptoms were obtained before the first session and after the tenth session of treatment. Veterans reported statistically significant reductions in self-reported, clinician-rated, and partner-rated effortful avoidance, emotional numbing, and overall PTSD severity. These data indicate that SAT offers promise as an effective treatment for PTSD avoidance symptoms. 相似文献

This paper identifies interrelationships between evidence-based practice (EBP), radical structuralism, and culture, arguing that culturally-specific beliefs and norms should be integrated into evidence-based, cross-cultural partnerships within child and family service systems. A single case study of family advocate training in evidence-based practice is provided as an illustration of, and impetus for, the development of a format for use with community-based and ethnically-diverse parent/family advocates. The lessons learned from teaching evidence-based practice to a parent advocate in a particular child welfare service system are highlighted. The use of enhanced roles for social workers and indigenous social capital and resources, such as family advocates as allies, is recommended to help achieve a greater degree of accountability, cooperation, and core understanding in the use of EBP. By training racially-diverse foster parents as mental health advocates to work collaboratively with policymakers, community groups, and family participants, proponents of EBP will reach and benefit more diverse populations. 相似文献

Workers who temporarily leave their country to perform semi‐ and unskilled work under contract in another country are a distinct category of labour migrants in the global division of labour (GDL). The small island of Mauritius is a relatively new destination for contractual international labour migrants. The Mauritian state is intimately involved in the labour migration system, playing a mediating role in positioning the island within the GDL and trying to optimise the routing of global production chains through Mauritius. The migrants originate mainly in China and India and are overwhelmingly concentrated in the island’s clothing and textile factories where they now comprise one‐fifth of the export processing zone workforce. The migrant space occupied by expatriate workers in Mauritius is tightly circumscribed, with little social interaction between them and Mauritian society. A chronicle of their collective protest between 2002 and 2005 highlights grievances that arise from the conditions they face as migrants. Pointing largely to the failure of industrial relations institutions, and having stirred xenophobic sentiments, these protests represent a catalyst for reform. While the numerical incidence and scale of labour migration to small islands may be small, their significance for GDL analysis and for the politics of migration demands attention. 相似文献

Models that purport to explain the interplay between dissidents and the state generally assert, either explicitly or implicitly,
that the path from state interests to action to outcomes is a linear one. Using the case of the United Klans of America (UKA)
in North Carolina, I argue that state efforts to exert social control upon a perceived threat are shaped by a range of internal
and external contingencies. In particular, I undertake a comparative analysis of two state agencies to demonstrate how a particular
mechanism—ambivalence, here conceptualized as the relational consequence of a mismatch between organizational culture and organizational goals—leads
to distinct, and sometimes heterogeneous, actions and outcomes not directly traceable to organizational mandates. Findings
lend insight into how endogenous organizational processes shape contentious political outcomes in potentially divergent ways. 相似文献
