高校新设专业学生思想特点及教育对策分析

高校新设专业的学生相对老专业的学生而言,思想波动性更大,思想状况更复杂,思想负担亦更重.高校新专业班主任工作要充分体现人文关怀精神,以学生为本,深入学生了解情况,及时掌握学生思想动向,做好思想引导工作;要注重与专业教师的联系与交流,提高学生对新专业的认知程度;要加强学习引导,培养专业兴趣,调动学生的学习积极性.只有这样,才能促进高校新设专业的大学生全面健康的成长.

Studying children in armed conflict: data production,social indicators and analysis

The authors seek to give an overview of ways in which social indicators relevant to research on children affected by armed conflict can be developed, and how such research can be carried out. Technical and methodological challenges involved in this pursuit are discussed. It is argued that data production must consider issues of definition and delineation of the phenomenon of war-affected children more actively than it does currently. An analytical approach is proposed, in which children’s characteristics in different situations, or in different stages of conflict, may be used as intakes to understanding how the social processes pertaining to life histories of children in armed conflict are created and reproduced.

Designing and integrating composite networks for monitoring multivariate gaussian pollution fields

Networks of ambient monitoring stations are used to monitor environmental pollution fields such as those for acid rain and air pollution. Such stations provide regular measurements of pollutant concentrations. The networks are established for a variety of purposes at various times so often several stations measuring different subsets of pollutant concentrations can be found in compact geographical regions. The problem of statistically combining these disparate information sources into a single 'network' then arises. Capitalizing on the efficiencies so achieved can then lead to the secondary problem of extending this network. The subject of this paper is a set of 31 air pollution monitoring stations in southern Ontario. Each of these regularly measures a particular subset of ionic sulphate, sulphite, nitrite and ozone. However, this subset varies from station to station. For example only two stations measure all four. Some measure just one. We describe a Bayesian framework for integrating the measurements of these stations to yield a spatial predictive distribution for unmonitored sites and unmeasured concentrations at existing stations. Furthermore we show how this network can be extended by using an entropy maximization criterion. The methods assume that the multivariate response field being measured has a joint Gaussian distribution conditional on its mean and covariance function. A conjugate prior is used for these parameters, some of its hyperparameters being fitted empirically.     

Enabling children’s deliberation in deliberative systems: schools as a mediating space

In recent years, there has been a growing scholarly interest in conceptualising schools beyond their educational functions, as sites and agents of democracy. Yet this interest is often underpinned by a narrow conception of democracy, focusing solely on schools’ public and social aspects. To capture the democratic potential of schools more fully, this article suggests adopting a deliberative systems approach, which conceptualises democracy as differentiated yet linked sites of democratic communications and views schools as one such site. Using this approach as a broader framework and drawing on the fieldwork conducted in two Japanese schools, this article identifies the condition under which schools can become a meaningful part of deliberative systems. It reveals that schools contribute to deliberative systems when they serve as a bridge between children’s everyday practices and deliberative actions in the public space. In light of the findings, this article suggests conceptualising schools as a ‘mediating space’.     

Payment by results in international development: Evidence from the first decade

Payment by results is a relatively new way of giving development aid, where a recipient's performance against pre‐agreed measures determines the amount of aid they receive. Advocates for the mechanism argue it provides donors with both a ready justification for maintaining aid budgets and better results through innovation and autonomy. It has proved popular, with most bilateral aid donors having at least experimented with the mechanism and the variety of measures stretching from individual health workers being paid for each procedure, to national governments being paid for students' test scores. However, there has not been a robust assessment of whether Payment By Results (PbR) achieves its aims for greater effectiveness. I synthesize the evidence from eight projects fully or partially funded by DFID, the recognized world leader on PbR. This represents the best evidence currently available, and is critically analysed using the leading theoretical framework that breaks each agreement into its constituent parts. I find no evidence that PbR leads to fundamentally more innovation or autonomy, with the overall range of success and failure broadly similar to other aid projects. This may partly be due to the current use of Payment by Results, with no readily identifiable examples of projects that truly meet the idealized PbR designs. Advocates of PbR may thus conclude the idea is yet to be tested. I argue PbR does not deal with the fundamental constraints that donors face, and so it is unsurprising that PbR is subject to the normal pressures that affect all aid spending.     

Getting low educated and older people into work: The role of fiscal policy

Raising employment, in particular employment among older individuals and low educated individuals, stands high on the agenda of policy makers in many OECD countries. Increased sensitivity in recent years to rising inequality has made the challenge only larger. In this paper we evaluate alternative fiscal policy scenarios to face this challenge. We construct and use an overlapping generations model for an open economy where individuals differ not only by age, but also by innate ability and human capital. The model allows us to study effects on aggregate employment, per capita income and welfare, as well as effects for specific age and ability groups. We show that well-considered fiscal policy changes can significantly improve macroeconomic productive efficiency, without increasing intergenerational or intragenerational welfare inequality. Our results strongly prefer a reduction in the labor tax rate on older workers and on all low-wage earners, financed by an overall reduction in non-employment benefits. An alternative financing option is to raise the consumption tax rate. These results are to be seen as long-run effects for economies at potential output.     

Parental Divorce,Residence Arrangements,and Contact Between Grandchildren and Grandparents

When parents divorce, grandparents can play a supportive role in the lives of their grandchildren, but a parental divorce may also put grandchild–grandparent ties under pressure. In this study the authors investigated how grandchildren of married and divorced parents differ in the frequency of face‐to‐face contacts with grandparents and how this is mediated by postdivorce residence arrangements. Based on the multi‐actor survey “Divorce in Flanders,” they used reports of contact provided by more than 1,000 grandchildren and compared them with more than 1,100 grandparent reports for validation. The results showed that grandchildren from divorced parents have fewer contacts with their grandparents than grandchildren whose parents are married but that it is the postdivorce residence arrangement of grandchildren that produces this result. When grandchildren live with their divorced father or in a shared residence arrangement, they even see paternal grandparents more often than grandchildren with married parents.     

Characterizing the systems of support for families of children with disabilities: A review of the literature

ABSTRACT

During early childhood, children require major support that is tailored toward their specific needs. For children with disabilities, families play a crucial part in providing the needed services. However, families often lack the knowledge, resources, and skills that would help them in overcoming challenges that arise while raising a child with disability. Although much research has focused on defining the needs of families with children with disabilities and the impact of disability on the family system, many questions remain. A comprehensive perspective is needed to identify the types of support families provide to the child with a disability, the impact of providing that support on family members, the support systems that are available to families, and the impact of support on society. This review consolidates the empirical research to date on family support during early childhood and outlines areas of research that need further exploration.
