An increasing number of genetic counselors are moving into non-clinical roles, where their primary duties do not involve direct patient contact. According to the National Society of Genetic Counselors Professional Status Survey in 2010, 23% of counselors working in non-clinical roles identified laboratory or genetic testing as their primary area of work. Using a survey, we identified 43 genetic counselors who work predominately in laboratory settings. The two primary tasks performed by participants, include acting as a customer liaison (95%) and calling out test results (88%). Nineteen participants (44.2%) also reported spending a considerable amount of time signing reports. The most prevalent areas of job satisfaction were support from laboratory directors (76.8%), autonomy (76.7%), interactions with clinicians (69.7%) and interaction with other genetics counselors (67.5%). This is the first study specifically looking at the roles of laboratory genetic counselors, which is an expanding area of genetic counseling.  相似文献

In a late notation from 1932, Husserl emphasizes the fact that a broad concept of ??apperception?? should also include, alongside his usual examples, the apprehension of objects as bearers of an individual or inter-subjective past, specifically ??indicated?? with them; thus, he distinguishes between apperceptions ??appresenting?? a simultaneous content (co-presentations), anticipatory apperceptions pointing to future incidents, and retrospective apperceptions referring to ??ad-memorized?? (hinzuerinnert, ad-memoriert) features and events. The latter sort of apperceptions are involved not only in our apprehension of historical traces and relics, but also in that of causal relations, familiar objects, and cultural objects in general. Following several later notations of Husserl concerning the topic of ??apperceptions,?? this paper outlines the specific intentional structure of retrospective or evocative apperceptions, analyzing their various possible forms.  相似文献

Almost 20?years ago, Jürgen Habermas launched the idea of constitutional patriotism as a proposed solution to the tension between citizenship and national identity in the European Union. Since then, constitutional patriotism has remained a key concept in debates on European Union (EU) citizenship and democracy. This article, as so many before it, scrutinizes the meaning and viability of the concept. Unlike most others, however, it focuses less on the content of the concept and more on the subjects to which it is assumed/supposed to apply. I argue, firstly, that constitutional patriotism is not a viable or even desirable ideal for the European demos in its totality. The potential patriots of the EU are not the large majority of European Union citizens who live in their home country but migrants from other member states and nonmember states who are foreigners in their host countries. Secondly and accordingly, I argue that advancing constitutional patriotism means improving the status of foreign nationals in general and third-country nationals in particular. Connecting the acquisition of EU citizenship to domicile as opposed to member state nationality is one venue for such improvement. I discuss what this could imply and defend it as a means of building a truly European demos.  相似文献

A distractor can be integrated with a target response and the subsequent repetition of the distractor can facilitate or hamper responding depending on whether the same or a different response is required, a phenomenon labeled distractor-response binding. In two experiments we used a priming paradigm with an identification task to investigate influences of stimulus grouping on the binding of irrelevant stimuli (distractors) and responses in audition. In a grouped condition participants heard relevant and irrelevant sounds in one central location, whereas in a non-grouped condition the relevant sound was presented to one ear and the irrelevant sound was presented to the other ear. Distractor-based retrieval of the prime response was stronger for the grouped compared to the non-grouped presentation of stimuli indicating that binding of irrelevant auditory stimuli with responses is modulated by perceptual grouping.  相似文献

The present study uses European Union (EU) enlargement as the treatment in a “natural” quasi experiment to analyze the relationship of threat appraisal and authoritarianism. Theoretically it is based on the discussion about the role of contextual variables in the genesis of authoritarianism. Two contradictory perspectives are explicated: the trait model and the situationist model. To test the competing causal hypotheses panel data collected before and after the EU eastern enlargement on perceived threat, authoritarian attitudes, and xenophobia among inhabitants of the German external frontier of the EU (at Wave 1) were analyzed. The use of a cross‐lagged panel design demonstrated that the type of relationship between authoritarianism and perceived threat depended on the kind of threat (material or cultural) that was addressed.  相似文献

The present studies tested whether people, particularly those who are most vulnerable to self-threats as indicated by low implicit self-esteem, adopt and express minority opinions to compensate for self-uncertainty. In Studies 1 through 3, low implicit self-esteem participants who were made to feel uncertain about themselves as individuals (versus uncertain about a self-irrelevant issue in Study 1, certain about themselves in Study 2, or uncertain about their group memberships in Study 3) expressed more disagreement with others' opinions. Additionally, Study 3 demonstrated that this effect is specific to minority opinions and does not emerge on majority opinions. In Study 4, the relation between self-uncertainty and disagreement with others' opinions was strongest among participants with both low implicit and high explicit self-esteem, who respond to self-threats in particularly defensive ways.  相似文献

This paper develops the first parts of a logical framework for the empirical sciences, by means of a redefinition of theory structuralism as originally developed by Joseph Sneed, Wolfgang Stegmüller, and others, in the context of a ??rigid?? logic as based on a fixed (therefore rigid) ontology. The paper defends a formal conception of the empirical sciences that has an irreducible ontological basis and is unable, in general, to provide purely structural characterizations of the domain of a theory. The extreme rationalist utopia of a characterization of the real world ??up to isomorphism??, therefore, is rejected.  相似文献
