Group concept mapping (GCM) has been successfully employed in program planning and evaluation for over 25 years. The broader set of systems thinking methodologies (of which GCM is one), have only recently found their way into the field. We present an overview of systems thinking emerging from a system dynamics (SD) perspective, and illustrate the potential synergy between GCM and SD. As with GCM, participatory processes are frequently employed when building SD models; however, it can be challenging to engage a large and diverse group of stakeholders in the iterative cycles of divergent thinking and consensus building required, while maintaining a broad perspective on the issue being studied. GCM provides a compelling resource for overcoming this challenge, by richly engaging a diverse set of stakeholders in broad exploration, structuring, and prioritization. SD provides an opportunity to extend GCM findings by embedding constructs in a testable hypothesis (SD model) describing how system structure and changes in constructs affect outcomes over time. SD can be used to simulate the hypothesized dynamics inherent in GCM concept maps. We illustrate the potential of the marriage of these methodologies in a case study of BECOMING, a federally-funded program aimed at strengthening the cross-sector system of care for youth with severe emotional disturbances.  相似文献

Group concept mapping is a systematic methodology that recognizes participants’ expertise in their own experiences. In this approach, participants share their diverse knowledge and interpret the data generated by all group members. This approach uniquely blends quantitative and qualitative techniques to create illustrative, structured conceptualizations. In this article, we describe the steps in group concept mapping and report feedback on this method from 37 children and youth who participated in group concept mapping studies. We recommend group concept mapping as an engaging way to involve children and youth in research and evaluation activities.  相似文献

To maintain a chance of occasionally beating a stronger player in a competition waged over several fields, a weaker player should give up on some of the fields and concentrate resources on the remaining ones. But when do weak players actually do this? And which fields do they give up when the fields differ in their likelihood of being assessed? We report an experimental study of resource allocation in which asymmetric pairs of players compete over asymmetric fields. Symmetric players and symmetric fields are used for control. We find that players behave as follows: (1) Average wins are the same in the symmetric and asymmetric fields conditions and correspond to relative player strength. (2) The proportion of fields given up on decreases with a player’s greater relative strength, increases for asymmetric field likelihoods, and increases when competitions are framed in meaningful context; this proportion is related to wins. (3) When field likelihoods are asymmetric, players’ resource allocation is correlated with likelihood. Wins generally increase with that correlation but the relation is different for players of different strength. (4) The proportion of fields given up on and the correlation with likelihood change with experience towards the values corresponding to higher wins.  相似文献

In the estimation of a proportion p by group testing (pooled testing), retesting of units within positive groups has received little attention due to the minimal gain in precision compared to testing additional units. If acquisition of additional units is impractical or too expensive, and testing is not destructive, we show that retesting can be a useful option. We propose the retesting of a random grouping of units from positive groups, and compare it with nested halving procedures suggested by others. We develop an estimator of p for our proposed method, and examine its variance properties. Using simulation we compare retesting methods across a range of group testing situations, and show that for most realistic scenarios, our method is more efficient.  相似文献

In this article, a new attributes double sampling plan for three-class products (ADSPTP) is presented, and the corresponding operating characteristic function is constructed based on the given procedure of performing ADSPTP. Average sample numbers (ASN) for complete inspection and curtailed inspection of the second sample are derived and the extreme point is discussed on the three-dimensional ASN surface. In addition, the differences arising from different parameters are studied. Sampling plans are designed by a nonlinear optimization model. Finally, numerical examples and discussions are given to illustrate the obtained results, and tables of the designed plans under various conditions are provided.  相似文献

社会资本在聋儿成长中具有非常重要的作用。重构聋儿社会资本成为社会康复的核心内容。在聋儿听力康复过程中,由于聋儿游戏群体的缺失、家长的认识偏误以及家长社会资本的不足等原因,导致聋儿社会资本不足的问题非常突出。文章从小组工作视角出发,提出通过组建聋儿游戏群体,增进聋儿家长社会资本,重构聋儿社会资本的建议。  相似文献

SUMMARY

Within the social work profession, one's world view, one's beliefs and values based on one's experiences, strongly influences one's practice and comfort with groups. This paper will examine some of the different ways of viewing the world held by practitioners and students in relation to the likelihood that they will be able to work effectively with groups. Such examination, and the identification of the differences among social workers that results from it has implications for both teaching and supervision in social work. These implications will be discussed and specific principles and techniques for teaching social workers, in education and in supervision, based on their world views will be described. This paper aims to enrich education for group work so that the community of social group work practitioners can grow and continue to thrive.  相似文献

回族是在中国历史上发展形成的一个民族群体,并对中国社会发生重大的影响。把民族与宗教信仰紧密联系在一起,是中国回族最突出的特点,也是最重要的特点。中国回族实际上是直接受到两种思想和两种文化的影响和教育。中国回族先民在融会贯通伊斯兰思想和儒家思想方面,有许多创新和独到之处,积累了丰富的经验,提出了许多切实可行的理论和观点,取得了很好的效果,也树立了不同思想和文化之间交流和对话的典范。今天,在新形势下,我们更应该发扬这种精神,积极创造条件,加强民族团结,促进社会和谐。  相似文献

曾经的辉煌与当下的衰败、曾经的核心与目前的边缘化所造成的失落感,三大圣地、《古兰经》与先知穆罕默德的相继蒙羞和遭辱所带来的受辱感,历史的创伤记忆与现实的生存困窘共同积淀成了一种顽强的集体潜意识,形成阿拉伯—伊斯兰民众仇恨与暴力相交织的心理死结,外现为以暴易暴、铤而走险甚至不断丧失自我。因此,阿拉伯—伊斯兰世界应在不断抵抗西方霸权主义对中东诸多利益的制衡中,努力变革滞后于全球化主潮的落后现状。否则,将面临更为严重的民族和地区的倒退,危及世界和平与稳定。  相似文献

In this article, we evaluate the relationship between supply chain design decisions and supply chain disruption risk. We explore two supply chain design strategies: (i) the dispersion of supply chain partners to reduce supply chain disruption risk versus (ii) the co‐location of supply chain partners to reduce supply chain disruption risk. In addition, we assess supply chain disruption risk from three perspectives: the inbound material flow from the supplier (supply side), the internal production processes (internal), and the outbound material flow to the customer (customer side) as a disruption can occur at any of these locations. We measure disruption risk in terms of stoppages in flows, reductions in flow, close calls (disruptions that were prevented at the last minute), disruption duration (time until normal operation flow was restored), and the spread of disruptions all the way through the supply chain. We use seemingly unrelated regression (SUR) to analyze our data, finding that lead times, especially supply side lead times, are significantly associated with higher levels of supply chain disruption risk. We find co‐location with suppliers appears to have beneficial effects to the reduction of disruption duration, and, overall supply side factors have a higher impact when it comes to supply chain disruption risk than comparable customer side factors.  相似文献
