The Social Fabric and Innovation Diffusion: Symbolic Adoption of Food Irradiation*

Abstract This study used a longitudinal, panel design to examine the effects of negative information acquisition, compliance with opinion leader endorsements, and social demographic characteristics on consumers' symbolic adoption of food irradiation. Data collection coincided with the first market test of irradiated food conducted by a commercial firm, which took place in Minneapolis, Minnesota, in 2000. Approximately half the subjects (N = 116) received a packet containing information from proponents and opponents of food irradiation. The remaining subjects (N = 107) were provided with no information about the technology. The results indicated that, initially, negative information acquisition, even when accompanied by positive endorsements from opinion leaders, decreased symbolic adoption. Over time, however, this negative effect was mitigated by compliance with endorsements from opinion leaders. The results suggest that confidence in social institutions might be a determinant as well as an outcome of adoption decisions. Implications are suggested for risk communication strategies regarding controversial agricultural technologies.     

Social capital, social inclusion and services for people with learning disabilities

Both social capital and social inclusion have emerged as significant concepts for human services in the last decade and yet their inter-relationship remains largely unexplored. This article argues that, whilst they are similar in their vision for a healthy society, they adopt sufficiently different perspectives to stimulate and challenge each other. This can be well illustrated by reference to services for people with a learning disability. Commissioners and providers of learning disability services are encouraged through this article to harness both concepts in order to assist in the process of modernizing services and increasing life opportunities for the people they support. It is argued that it is not possible to understand the full consequences of adopting either theoretical position without an adequate understanding of the other. Examples are given of the implications of this for advocacy services, day opportunities, rural communities, transition and staff training.     

THE NEUROBIOLOGY OF AFFECTIVE INTERVENTIONS: A CROSS-THEORETICAL MODEL

The integration of information from neuroscience with the practice of psychotherapy presents with numerous challenges. However, neuroscience research can guide practitioners in the purposeful use of the therapeutic relationship to enhance clinical outcomes. This article reviews such research pertinent to mental health and psychotherapy, and presents an a-theoretical model of intervention, guided by this information that can be incorporated into various therapeutic orientations.     

Cultural cross‐currents in second language literacy education

This paper discusses the concept of ‘cultural cross‐currents,’ their implicit nature and the potential they have to effect second language literacy learning, teaching and curriculum reform in Hong Kong primary classrooms. Despite the substantive implications for learning, the exploration of cultural influences upon teacher and student thinking and the resultant educational consequences, remains a largely unrecognized area. The central argument in the paper is that cultural differences in attitudes, beliefs and values of cultural groups toward the way first and second languages are acquired needs to be made explicit in order to facilitate second language literacy teaching and learning.     

Shareholders’ Voting at General Meetings: Evidence from the Netherlands

We study annual general meetings of shareholders in the Netherlands. The Dutch corporate governance system is characterized by relatively concentrated shareholdings and large stakes owned by pension funds, banks and insurance companies. The legal protection of shareholders is poor due to the presence of takeover defenses, such as certificates, which deprive shareholders from their voting rights. An analysis of the minutes of 245 general meetings in the period 1998–2002 reveals that on average 30% of the equity capital is represented at the meeting. All proposals at the meeting are sponsored by the management and only 9 out of 1,583 proposals are rejected or withdrawn. Our analyses show that pension funds are the most active and critical shareholders at the meetings, while certificates effectively restrict shareholder rights. Our main conclusion is that the general meetings do not provide shareholders in the Netherlands any significant influence on management.     

Adapting to Climate: A Case Study on Riverine Flood Risks in the Netherlands

Climate change may well lead to an increased risk of river floods in the Netherlands. However, the impacts of changes in water management on river floods are larger, either enhancing or reducing flood risks. Therefore, the abilities of water-management authorities to learn that climate and river flows are changing, and to recognize and act upon the implications, are of crucial importance. At the same time, water-management authorities respond to other trends, such as the democratization of decision making, which alter their ability to react to climate change. These complex interactions are illustrated with changes in river flood risk management for the Rhine and the Meuse in the Netherlands over the last 50 years. A scenario study is used to seek insight into the question of whether current water-management institutions and their likely successors are capable of dealing with plausible future flood risks. The scenarios show that new and major infrastructure is needed to keep flood risks at their current level. Such a structural solution to future flood risks is feasible, but requires considerable political will and institutional reform, both for planning and implementation. It is unlikely that reform will be fast enough or the will strong enough.     

A Non-Gaussian Spatial Process Model for Opacity of Flocculated Paper

ABSTRACT.  Product quality in the paper-making industry can be assessed by opacity of a linear trace through continuous production sheets, summarized in spectral form. We adopt a class of non-Gaussian stochastic models for continuous spatial variation to describe data of this type. The model has flexible covariance structure, physically interpretable parameters and allows several scales of variation for the underlying process. We derive the spectral properties of the model, and develop methods of parameter estimation based on maximum likelihood in the frequency domain. The methods are illustrated using sample data from a UK mill.     

Child,Caregiver, and Temperament Contributions to Infant Joint Attention

Little is known about variables that may contribute to individual differences in infant joint attention, or the coordination of visual attention with a social partner. Therefore, this study examined the contributions of caregiver behavior and temperament to infant joint attention development between 9 and 12 months. Data were collected from 57 infants using a caregiver–infant paradigm, an infant–tester paradigm, and a parent report of infant temperament. Nine‐month measures of caregiver scaffolding and infant initiating joint attention (IJA) with testers were significantly related to 12‐month infant IJA with testers. A temperament measure of positive emotional reactivity was related to 9‐month IJA, and a measure of negative emotional reactivity was related to 12‐month IJA. Temperament and caregiver scaffolding measures, however, were not associated with the development of infant responding to joint attention. These results further the understanding of the multiple processes that contribute to joint attention development in infancy, and support the hypothesis that initiating and responding measures tap different aspects of joint attention development.
