Knowledge of a language is a kind of knowledge, the possession of which enables a speaker to understand and perform a variety of linguistic actions in that language. In this paper, I pursue an agency-oriented approach to knowledge of language. I begin by examining two major agency-oriented models of knowledge of language: Michael Dummett's Implicit Knowledge Model and Jennifer Hornsby's Practical Knowledge Model. I argue that each of these models is inadequate for different reasons. I present an Acquaintance Knowledge Model, in which a speaker's knowledge of a language is a combination of the speaker's first-order linguistic ability and second-order acquaintance with his ability and actions. 相似文献

Access to food as a critical factor in determining individuals’ well-being in low income countries is of grave importance both in theory and public policy. Therefore this study, designed to enhance our understanding of food (in)security’s impact on quality of life, presents a micro-level analysis of factors associated with food provision, food satisfaction, and happiness in Ghana. Our empirical analysis first investigates the patterns and variations of food provision among Ghanaian households, and then evaluates how the provision factors, along with other socio-economic status and reciprocal behaviors, affect avowed well-being as measured by (1) the household heads’ subjective sense of being nonpoor and (2) reported feelings of happiness. The data are drawn from the Core Welfare Indicators Questionnaire (CWIQ) survey conducted in 2003, with a sample of 40,481 households. Regression outcomes reveal that the usage of land, owning of livestock and amount of food spending particularly favor male-headed households’ food security, which in turn leads men not to endorse “feeling poor” and, instead, to report greater happiness than is the case, in most instances, for women. Familial reciprocity also strengthens subjective well-being by way of increasing food security among Ghanaians. Family values as such, rather than decline in significance, appear to play a critical role in food security in Ghana. 相似文献

On the basis of the idea that a quasicrystal is a compound in which the average number of valence electrons per atom is around 2.0 and that its formation is dominated by atom size, stable icosahedral quasicrystals have been successfully synthesized in Ag-In-Ca, Ag-In-Yb, Ag-In-Ca-Mg and Ag- In-Yb-Mg systems. The Ag-In-Ca and Ag-In-Yb icosahedral quasicrystals have stoichiometry around Ag 42 In 42 Ca 16 and Ag 42 In 42 Yb 16 . The Ag-In-Ca-Mg and Ag-In-Yb-Mg quasicrystals form in the composition ranges Ag42 x /2 In 42 x /2 Ca 16 Mg x ( x =0-7.5 at.%) and Ag 42 x /2 In 42 x /2 Yb 16 Mg x ( x =0-10 at.%). Electron diffraction studies confirmed that the icosahedral quasicrystals have a primitive lattice. The average number of valence electrons per atom in all these quasicrystals is 2.0. 相似文献

Single Al-Pd-Re icosahedral quasicrystals with a maximum diameter of 5mm have been grown by a slow cooling method on the basis of a partial phase diagram determined in the present study. Laue X-ray and electron diffraction verified the highly ordered structure of the single icosahedral quasicrystals. The electrical resistivity rho of the single quasicrystals was measured to be 2000- 4000muOmegacm at 300K and 3000-6000muOmegacm at 2K, revealing a negative temperature dependence with a rho4.2K/rho300K value smaller than 2. 相似文献

This is the first study to examine how types of ethical work climates (EWCs) are related to facets of organizational citizenship behavior (OCB) in military units. Research hypotheses were examined using sample data collected from 508 military officers in Taiwan. The results indicated that the overall EWC and some climate types are significantly positively or negatively associated with overall OCB, OCB-organization (OCBO), OCB-individual (OCBI), and in-role behavior (IRB). Implications of EWC and practical management are discussed, and directions for future research are suggested. 相似文献

The current study examined the community characteristics and migration of chronically homeless adults before and after entry into a multi-site supported housing initiative. A total of 394 participants were geocoded at baseline and 12-month follow up. Data from geographic information systems indicate that the median distance participants traveled from their last residence to their residence 1 year after program entry was 4.6 miles and 12% of participants traveled more than 100 miles. Participants moved into communities with higher population densities, larger proportions of Whites, and smaller proportions of Blacks following their entry into supported housing, but continued to live in communities with higher crime rates, lower education levels, and lower income levels then the state average. At 12 months, Black participants residing in communities with higher population densities and larger Black populations reported higher social support and lower subjective distress. This underscores the importance of considering client preferences in housing. Together, these findings suggest that supported housing programs may be successful in finding housing for homeless clients, but are not placing them in improved communities. Special attention may also be needed for some clients who travel long distances between residences. 相似文献

Patients with behavioral variant frontotemporal dementia (bvFTD) can make false statements consistent with delusions or confabulations. It is unclear whether bvFTD is primarily associated with either delusions or with confabulations and whether they can be explained by the pathophysiology of this disease. In order to clarify this, we retrospectively surveyed the records of 48 patients with bvFTD for the presence of any false reports and identified four patients. Their false reports included continued interaction with a favorite but dead relation, fictitious marriages with movie stars, and two who claimed that their partner was having an affair. When confronted with the falsity of their statements, the patients conveyed a lack of certainty regarding their external or internal source but persisted in the constancy of their reports. On functional neuroimaging, the patients had predominant frontal involvement. This report found that patients with bvFTD can have both fantastic, wish fulfilling confabulations and typical content-specific delusions. We propose that both phenomena result from known disturbances of ventromedial prefrontal cortex in bvFTD, including deficits in source monitoring and in activating an automatic "doubt tag" for false reports. 相似文献

In many countries, undergraduates are required to take at least one introductory computer course to enhance their computer literacy and computing skills. However, the application software education in Taiwan can hardly be deemed as effective in developing students' practical computing skills. The author applied online self-regulated learning (SRL) and collaborative learning (CL) with initiation in a blended computing course and examined the effects of different combinations on enhancing students' computing skills. Four classes, comprising 221 students, participated in this study. The online SRL and CL with initiation (G1, n?=?53), online CL with initiation (G2, n?=?68), and online CL without initiation (G3, n?=?68) were experimental groups, and the last class, receiving traditional lecture (G4, n?=?32), was the control group. The results of this study show that students who received the intervention of online SRL and CL with initiation attained significantly best grades for practical computing skills, whereas those that received the traditional lectures had statistically poorest grades among the four classes. The implications for schools and educators who plan to provide online or blended learning for their students, particularly in computing courses, are also provided in this study. 相似文献

This research examined both the effects of various corporate image dimensions on organizational attractiveness and the moderating effects of applicant individual difference variables on the aforementioned relationships. Two studies were conducted for this research, which involved 40 bank samples and 360 student participants ( Study 1 ) and 538 employee–student mixed samples ( Study 2 ). By implementing different research designs, samples, and industry targets in the two studies, we found that corporate product image, corporate citizenship image, and corporate credibility image were important antecedents to organizational attractiveness. One of the proposed applicant individual difference variables, environmental sensitivity, was found to moderate the relationship between corporate citizenship image and organizational attractiveness. 相似文献

Both direct placement in supported community housing and pre-treatment with time-limited residential treatment are used as approaches to helping chronically homeless adults exit from homelessness but relative effectiveness and cost remains untested. The current observational study utilized data from a national, multi-site housing project to determine whether clients who receive residential treatment or transitional housing before being placed into independent housing achieve superior outcomes than clients who are immediately placed into independent housing, and whether they incur greater healthcare costs. A total of 709 participants (131 and 578 participants in the respective groups) were assessed every 3 months for 2 years on housing outcomes, community adjustment, work and income, mental and physical health, and health service costs. Clients who received immediate, independent housing had more days in their own place, less days incarcerated, and reported having more choice over treatment; but no differences on other clinical or community adjustment outcomes. In this observational study, there were no clinical advantages for clients who had residential treatment or transitional housing prior to entry into community housing, but they incurred higher substance abuse service costs. Studies using randomized controlled trials of these conditions are needed to establish causation. 相似文献
