Value added is a common tool in educational research on effectiveness. It is often modeled as a (prediction of a) random effect in a specific hierarchical linear model. This paper shows that this modeling strategy is not valid when endogeneity is present. Endogeneity stems, for instance, from a correlation between the random effect in the hierarchical model and some of its covariates. This paper shows that this phenomenon is far from exceptional and can even be a generic problem when the covariates contain the prior score attainments, a typical situation in value added modeling. Starting from a general, model-free definition of value added, the paper derives an explicit expression of the value added in an endogeneous hierarchical linear Gaussian model. Inference on value added is proposed using an instrumental variable approach. The impact of endogeneity on the value added and the estimated value added is calculated accurately. This is also illustrated on a large data set of individual scores of about 200,000 students in Chile. 相似文献

A fundamental approach of theology as practiced within the palliative setting is care for the whole human being, with particular focus on spirituality and the spiritual dimension. Theology and medicine come together in palliative care in which the spiritual aspect is an important component together with the physical, psychological, and social. This article is based on a mixed methods study of spirituality among persons receiving palliative care. Findings revealed the importance of spirituality and its multidimensional elements by which spirituality was perceived as a complex phenomenon relating to religious and non-religious aspects of human life. Theological reflection based on the present findings indicates that a sharp distinction between the concepts of religion and spirituality is not beneficial. It also reveals the significance of the spiritual dimension and that theology has an important role in creating a deeper understanding of this complex part of human existence. Spiritual needs, expressed in various ways, were evident among the participants receiving palliative care. The findings confirm that the theological approach in palliative care, with its focus on the whole human being and emphasis on spirituality and the spiritual dimension, continues to be the hallmark of practicing theology within palliative care. 相似文献

Autism shows a high degree of comorbidity with anxiety disorders. Adolescence is a time of increased stress and vulnerability to internalising problems. This study addresses for the first time the degree of genetic and environmental overlap between autistic traits (total measure and subscales) and internalising traits in a community-based adolescent twin sample. Parents of 12-14-year-old twins (N?=?3,232 pairs; 3,460 males, 3,004 females) reported on the twins’ internalising and autistic traits. Autistic trait subscales were created using principal component analysis. Bivariate twin model-fitting was conducted. Autistic and internalising traits correlated moderately (r?=?0.30). Genetic influences on individual traits were substantial but genetic overlap between traits was moderate (genetic correlation: males?=?0.30, females?=?0.12). Shared environmental influences were low for internalising traits and moderate for autistic traits, and showed considerable overlap (shared environmental correlation: males?=?0.53, females?=?1). Nonshared environmental influences were moderate for internalising traits and low for autistic traits and showed low overlap. A multiple component solution was found for autistic traits and of the derived subscales, autistic-like ‘Social Unease’ showed the most phenotypic and genetic overlap with internalising traits. 相似文献

In this work, the first of a series, we study the nature of informal inconsistency in physics, focusing mainly on the foundations of quantum theory, and appealing to the concept of quasi-truth. We defend a pluralistic view of the philosophy of science, grounded on the existence of inconsistencies and on quasi-truth. Here, we treat only the ‘classical aspects’ of the subject, leaving for a forthcoming paper the ‘non-classical’ part. 相似文献

The traditional Square of Opposition consists of four sentence types. Two are universal and two particular; two are affirmative and two negative. Examples, where ‘S’ and ‘P’ designate the subject and the predicate, are: ‘every S is P’, ‘no S is P’, ‘some S is P’ and ‘some S is not P’. Taking the usual sentences of the square of opposition, quantifying over their predicates exhibits non-standard sentence forms. These sentences may be combined into non-standard Squares of Opposition (an Octagon in this case), and they reveal a new relationship not found in the usual Square. Medieval logicians termed ‘disparatae’ pairs of sentences like ‘every S is some P’ and ‘some S is every P’, which are neither subaltern nor contrary, neither contradictory nor subcontrary. Walter Redmond has designed a special language L to express the logical form of these sentences in a precise way. I will use this language to show how Squares of Opposition, standard and non-standard, form a complex network of relations which bring to light the subtleties contained in this traditional doctrine. 相似文献

The perennial “nativist-empiricist” debate in developmental science has far-reaching relevance in our existence. Two studies conducted under the terror management framework tested whether the empiricist developmental conception serves distal defensive purposes. Experiment 1 highlights the palliative existential effect of the empiricist conception since participants who read an empiricist essay exhibited less death thoughts than participants who read a nativist essay or a control essay. Experiment 2 gives support to the distal defensive function of the empiricist conception by showing that, unlike with the nativist or the control essay, people under mortality salience exhibited a higher need to rely on empiricism than participants in the control pain condition. The existential advantage of empiricism is explained by the fact that human development is shaped by a meaningful cultural blueprint. Our results are discussed in terms of the ontological and existential benefits of contemplating human intrinsic identity, ranging from its biology to its social behaviors as primarily influenced by the cultural environment. 相似文献

While cognitive scientists increase their tentative incursions in the social domains traditionally reserved for social scientists, most sociologists and anthropologists keep decrying those attempts as reductionist or, at least, irrelevant. In this paper, we argue that collaboration between social and cognitive sciences is necessary to understand the impact of the social environment on the shaping of our mind. More specifically, we dwell on the cognitive strategies and early-developing deontic expectations, termed naïve sociology, which enable well-adapted individuals to constitute, maintain and understand basic social relationships. In order to specify the way in which the demanding character of typical social relationships can be recognized in situ, we introduce the concept of “deontic affordances”. Finally, we shed light on the continuum that might relate a primitive naïve sociology, dedicated to the processing of invariant properties of the social life and a mature naïve sociology, necessary for dealing with the variable properties of cultural forms of life. 相似文献

Experiential learning opportunities are powerful in shaping positive supervisor behaviours. We were interested in examining the positive experiences of supervisors-in-training during their first practice experience as supervisors. Our study was guided by two research questions: (a) what are the experiences that supervisors-in-training viewed as positive during the course of providing clinical supervision to master's-level counselling trainees? and (b) how did these positive experiences contribute to their professional development? We employed a variation of the consensual qualitative research method developed by Hill, Thompson, and Nutt-Williams (1997) and interviewed 10 supervisors-in-training regarding their positive experiences in supervising master's-level counselling trainees. The results included five major categories of positive experiences: (a) the positive value of feedback; (b) enhanced confidence in using a wider variety of supervision tasks and procedures; (c) the impact of the experience on other aspects of professional practice; (d) increased familiarity with the multiple roles of the supervisor; and (e) for some, increased comfort navigating co-supervision dynamics. Each of these categories included subcategories. We discuss our findings within the context of supervision training in graduate education. 相似文献
