Relations between mothers’ mind‐mindedness (appropriate attunement to their infants’ internal states) at 6 and 12 months and infants’ early symbolic play during infant–mother pretense at 12 and 18 months were investigated in a sample of 43 mothers and infants. Mothers’ appropriate mind‐related comments were associated with average level, length, complexity, and maturity level of symbolic play. Specific sub‐categories of appropriate mind‐related comments were identified as independent predictors of children's symbolic play. Appropriate comments about desires and cognitions at 6 months were associated with average level and length of episodes, as well as with maturity level of symbolic play at 12 months. Longitudinal stability in the appropriateness and content of mothers’ mind‐related comments was also investigated. The results are discussed in terms of the proposal that attunement to specific types of internal state should vary as a function of infant age in order to index mind‐mindedness.  相似文献

Despite the wealth that comes from being the biggest oil producer in Africa, Nigeria has some of the worst development indicators in the world. From 2011 to mid‐2016, the DFID‐funded Facility for Oil Sector Transparency and Reform (FOSTER) programme's unique design aimed to reduce incentives for the capture of oil revenue by elites and international oil companies, restoring the potential of those revenues to accelerate economic and social development. This article asks what lessons FOSTER's successes and failures offer for improved “thinking and working politically” (TWP). It examines the outcomes from five “clusters” of interventions: three viewed by the FOSTER team as successes and two as failures. The article identifies factors for successful TWP‐based programming, including the need for local ownership rooted in staff with a combination of technical expertise, a deep knowledge of the local political context and excellent networking abilities. The research used a qualitative and inductive approach. Field research was undertaken with 44 semi‐structured qualitative interviews during one month of fieldwork in Abuja and Lagos. The research also included reviews of FOSTER's internal documentation and evaluation frameworks, as well as analysis of newspaper articles and grey literature on the oil sector in Nigeria. The project offers important lessons for politically informed programming about how interventions were implemented (process), what was actually done (content) and how the project responded to changes in context that created or blocked opportunities for reform (responsiveness). The article identifies factors for successful TWP‐based programming, including the need for local ownership rooted in staff with a combination of technical expertise, a deep knowledge of the local political context and excellent networking abilities. The findings have important implications for programme design. They demonstrate the value of built‐in flexibility that allows staff to choose and switch the partners they work with and the channels they work through. They also show that a key aspect of TWP‐based programming is implicit acceptance that some failure may be unavoidable, since this permits staff to balance risk against opportunities. Finally, a better understanding of FOSTER's failures reveals the challenges of a TWP‐based approach and the trade‐offs it demands.  相似文献

In this paper, we introduce a multilevel model specification with time-series components for the analysis of prices of artworks sold at auctions. Since auction data do not constitute a panel or a time series but are composed of repeated cross-sections, they require a specification with items at the first level nested in time-points. Our approach combines the flexibility of mixed effect models together with the predicting performance of time series as it allows to model the time dynamics directly. Model estimation is obtained by means of maximum likelihood through the expectation–maximization algorithm. The model is motivated by the analysis of the first database ethnic artworks sold in the most important auctions worldwide. The results show that the proposed specification improves considerably over classical proposals both in terms of fit and prediction.  相似文献

The objective of this article is to discuss a needed paradigm shift in disaster risk analysis to emphasize the role of the workforce in managing the recovery of interdependent infrastructure and economic systems. Much of the work that has been done on disaster risk analysis has focused primarily on preparedness and recovery strategies for disrupted infrastructure systems. The reliability of systems such as transportation, electric power, and telecommunications is crucial in sustaining business processes, supply chains, and regional livelihoods, as well as ensuring the availability of vital services in the aftermath of disasters. There has been a growing momentum in recognizing workforce criticality in the aftermath of disasters; nevertheless, significant gaps still remain in modeling, assessing, and managing workforce disruptions and their associated ripple effects to other interdependent systems. The workforce plays a pivotal role in ensuring that a disrupted region continues to function and subsequently recover from the adverse effects of disasters. With this in mind, this article presents a review of recent studies that have underscored the criticality of workforce sectors in formulating synergistic preparedness and recovery policies for interdependent infrastructure and regional economic systems.  相似文献

ABSTRACT

This paper explores the intersections of formal and informal care in the relationships that develop between elderly care receivers and their families and migrant domestic care workers and their families. The domestic migrant care literature has tended to focus on two main ‘hidden costs’ of this ‘care-chain’: the ‘care exploitation’ of paid carers by their employers and the ‘care drain’ impact on the family members left behind by the migrant. In this paper, we employ a care circulation framework to examine the process of becoming kin-like – or ‘kinning’, which remains relatively under-explored and warrants further research. An analysis of this process of kinning helps to highlight how the domestic space of care receiver homes are transformed – through the negotiation of relationships with migrant care workers – into transnational social fields that bring the diaspora worlds of the migrants into the everyday worlds of the locals.  相似文献

A group of pathological gamblers and a group of problem gamblers (i.e., gamblers at risk of becoming pathological) were compared to healthy controls on their risk-taking propensity after prior losses. Each participant played both the Balloon Analogue Risk Taking task (BART) and a modified version of the same task, where individuals face five repeated predetermined early losses at the onset of the game. No significant difference in risk-taking was found between groups on the standard BART task, while significant differences emerged when comparing behaviors in the two tasks: both pathological gamblers and controls reduced their risk-taking tendency after prior losses in the modified BART compared to the standard BART, whereas problem gamblers showed no reduction in risk-taking after prior losses. We interpret these results as a sign of a reduced sensitivity to negative feedback in problem gamblers which might contribute to explain their loss-chasing tendency.  相似文献

Prior research on media representations of race, gender, and sexual violence has established that media emphasize women’s role in preventing their own victimization and omit Black women as victims. This study uses feminist intersectionality to build on prior research by investigating not only how social groups are portrayed, but whether and how the intended audience matters for media representations. Specifically, who are the portrayed victims of sexual violence, and how is fear of sexual violence communicated to different audiences? Content analysis of articles in race- and gender-specific magazines shows two key mechanisms of representation through which racism and sexism work together: visibility and denial. Results show that White women are hypervisible as victims while Black women as victims are relatively invisible compared to Black men’s persecution and Black children’s victimization; men’s magazines deny the importance of sexual violence as a problem, focusing on false accusations and convictions. These narratives go largely unchallenged regardless of the source’s intended audience, demonstrating that portrayals of sexual violence are both gendered and racialized across multiple media sources.  相似文献

In this study of over 2000 mothers, we considered the alignment between employment preference and status, examining the well-being of mothers who were employed and wanting to work; employed because they need the money; not employed and not wanting work; and not employed but wanting to work. Alignment between employment preference and employment status was significantly associated with well-being, and mothers who stayed at home but wanted work had the most difficulties. Strong associations across multiple outcomes were found for emotional support variables, and costs of childcare was the most common reason for staying home even if employment was desired. Results suggest the importance of women’s self-agency in employment decisions, access to child-care, and emotional support in mothers’ lives.  相似文献

The 21st century will face an increased population with limited resources. The latest projection of the United Nations estimates an additional 1.65 billion people by 2030. The rising population should access to all modern services and welfare. Resources demand is expected to increase dramatically in the 21st century, especially in developing countries, where population growth is fast and billions of people nowadays have no access to these services. If no new, strong energy-policy interventions occur, the world’s energy needs will be well over 50% higher in 2030 than today. Fossil fuels will continue to dominate world fuel mix (IEA, International Energy Agency, in World energy outlook 2007, Paris, 2008). The consequent growth in energy-related emissions of carbon-dioxide is noteworthy. The challenge is to reach an energy system allowing this growth and assuring security, reliability, and environmental protection. With worldwide demand for energy expected to more than double by 2030, the need for safe, clean, reliable energy is essential. Much of greenhouse gasses emissions is due to the energy sector. Energy supply, generation and use (and its environmental consequences) is definitely the issue of our times and the coming. All technologies may be complimentary for fitting the demand. Known means exist to cut energy demand and change the fuel mix. In this paper, we will introduce the energy issue and show which role nuclear energy could have in reducing emissions.  相似文献
