Billions of dollars and hundreds of millions of hours are invested every year in executive education. However, much of this investment dies in a familiar “Valley of Death” (VoD) wherein what is learned in the classroom is not applied when the strategist returns back to work. Based on 30 in-depth interviews and live observation, we investigate the architecture of an executive education program designed to avoid the VoD. In the observed program, senior partners of a strategy consulting firm, and their key strategist clients, are brought together to co-learn strategy associated with scenario planning, and, at the same time, improve their ongoing business relations. We find that adopting a “paired learning structure” and utilizing “live case content” results in “group-level co-learning” (or the co-production of knowledge) that, participants report, avoids the VoD. This research contributes to the scholarship on learning architecture in executive education by establishing linkages to the literature on client-partner relationships, modelling the student, and service co-production in knowledge-intensive organizations, and, in the end, provides a blueprint that professional service firms and business schools, seeking to produce more value for their participants, can jointly emulate. 相似文献

Multistage clonal expansion (MSCE) models of carcinogenesis are continuous‐time Markov process models often used to relate cancer incidence to biological mechanism. Identifiability analysis determines what model parameter combinations can, theoretically, be estimated from given data. We use a systematic approach, based on differential algebra methods traditionally used for deterministic ordinary differential equation (ODE) models, to determine identifiable combinations for a generalized subclass of MSCE models with any number of preinitation stages and one clonal expansion. Additionally, we determine the identifiable combinations of the generalized MSCE model with up to four clonal expansion stages, and conjecture the results for any number of clonal expansion stages. The results improve upon previous work in a number of ways and provide a framework to find the identifiable combinations for further variations on the MSCE models. Finally, our approach, which takes advantage of the Kolmogorov backward equations for the probability generating functions of the Markov process, demonstrates that identifiability methods used in engineering and mathematics for systems of ODEs can be applied to continuous‐time Markov processes. 相似文献

To date, the gaps between actual and preferred working hours are mostly theorised and analysed at the individual level. This article provides new insights as to what extent different household arrangements relate to matches or mismatches concerning the achievement of a desired time allocation. The concept of household governance refers to regulations and practices families apply to keep work–family relationships under control, like the earner model, outsourcing of household task and household rules. This article explores by linear regression analyses how these are related to time-use problems of families: the gap between actual and preferred working hours, lack of free time and the experience of time pressure. The rivalling perspectives of flexibility, regulation and boundary theory have different predictions as to which modes of governance produce favourable outcomes. The results generally support boundary theory. However, households often are unable to choose their earner model optimally. 相似文献

In recent years, the Madrid Region (Comunidad de Madrid) has experienced a huge increase in immigrants accessing the labour market. In this paper, a dynamic input‐output exercise is presented, yielding the direct and indirect effects of this migration inflow on the Madrid GDP. In addition, the induced demand effect is estimated, offering a complete estimate framework of the impact of migrant access on regional value added. 相似文献

During the child's first few years, it's of fundamental importance the presence of a strong emotional base as long as it creates the possibility to open themselves to physical and social world with confidence, and as it acts as a facilitator of cognitive development. For this reason, if the family cannot ensure such base, social services are forced to resort to foster care, a resource that has a lot of difficulties, leading to different implications in the development of the child and of the foster family. It is therefore important to analyze in depth the socio-emotional variables that characterize children who are in a situation of foster care in order to provide adequate assistance to optimize their development. For this 32 minors in foster care, 31 foster parents and 28 teachers from the city of Valencia, were administered the BASC. The results highlight that parents are evaluating children, in general, worse than tutors. Specifically they consider children more aggressive, they detect more behavioral and attention problems and recognize in them a greater tendency to externalize the problems, while the teachers consider these children as with more social and adaptive skills. There were no significant differences between the scores of parents, teachers and children. High levels of psychopathology (which are clinically significant in various cases) and the fact that host parents evaluate minors as more problematic, are indicators of parents' and minors' need of support from public organizations. 相似文献

AbstractBullying presents a significant social distress for students, families and schools. Concerned practitioners and researchers are invested in developing interventions to decrease the frequency and negative impact of bullying. To do so, however, understanding the cast of characters in the bullying drama is critical. This paper reviews selected research on characteristics of bullies, victims and bystanders from a variety of theoretical and methodological approaches. The implications of these characteristics for effective interventions is considered. The role of socio-economic factors is presented, and their relevance for communities and policy makers discussed. 相似文献

Few studies directly address the consequences of habitat fragmentation for pollinating insect communities, particularly for the neotropical key pollinator group of stingless bees. Most studies on bees have defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Their conclusion is that habitat fragmentation is broadly deleterious; however, there are contrasting results in the literature. Insightful studies on habitat fragmentation and bees should consider fragmentation, alteration and loss of nesting habitats—not just patches of forage plants –, as well as the permeability of the surrounding matrix to interpatch movement. Here we investigated the effects of fragmentation caused by urbanization on stingless bee species’ composition and richness, as well as the permeability of the surrounding matrix. We collected bees from flowering plants and recorded phytosociological variables of five forest remnants (ranging from 64 ha to 900 ha) in southeastern Brazil. Large fragments did not contain more species per unit area than smaller ones; in fact, we found more species in small fragments, most of which were generalist bees. The presence of more habitat generalist stingless bee species was also correlated to the structure of vegetation in these fragments. In conclusion, the quality of the habitat within a fragment (structure of vegetation) as well as the quality of the matrix has a direct relation to the bee species composition. This can be seen in the direct relationship between structural diversity of the environment and age of the fragments. The matrix that holds the most recent fragments, probably due to the sprawl of the city, is more heterogeneous than the one with the oldest fragments. The most heterogeneous matrices have a certain balance between the trees, buildings and bare soil or herbaceous vegetation coverage, making the array less impermeable to bees. 相似文献
