AbstractWork avoidance, or the goal to reduce effort in an achievement context, is related to disengagement and may offer insight into disengaged students and employees. To shed light on this issue, we investigated the antecedents of work avoidance in academic and work contexts to distinguish it from mastery, performance-approach, and performance-avoidance goals. Two samples of employed college students (N?=?207, N?=?233) completed questionnaires about their jobs and in one sample about their introductory psychology class. Across both contexts, proposed antecedents of alienation, low need for achievement, and perceiving one’s competence needs as not being met predicted work avoidance. Work avoidance also accounted for additional variance when combined with achievement goals to predict citizenship behaviors, perceiving work/classwork as meaningless and wanting to leave/quit. 相似文献
Masking the bitter taste of drugs is a potential tool for the improvement of patient compliance, which in turn decides the
commercial success of the product. To improve the palatability of a pharmaceutical product, many techniques have been developed,
which have not only improved the taste of the product, but also the stability of the drug in the formulation and performance
of the product. This article is an attempt to review strategies, technologies and tools that are used by pharmaceutical scientists
for taste-masking. 相似文献
The proliferation of mobile computing technologies is playing major role in the growth of mobile learning (M-learning) market around the globe. The purpose of this paper is to develop a research model in the lines of commonly used models the Unified Theory of Acceptance and Use of Technology (UTAUT) and Technology Acceptance Model (TAM) by incorporating constructs namely flexibility learning, social learning, efficiency learning, enjoyment learning, suitability learning, and economic learning that can predict M-learning adoption in a developing country. The data were collected from 388 students from all major universities/colleges in the capital city (Muscat) of Oman. The neural network modeling was employed to predict M-learning adoption. The neural network modeling results showed that flexibility learning, social learning, efficiency learning, enjoyment learning, suitability learning, and economic learning variables have significant influence on the intention of students to accept mobile learning. The key outcomes of this study suggest important determinants that can assist academic administrators and telecommunication service providers to enhance the adoption of M-learning with the help of suitable strategy. 相似文献
Studies were conducted under pot conditions to determine the comparative efficacy of carbofuran at 1 mg a.i./kg soil, bavistin
at 1 mg a.i./kg soil, neem (Azadirachta indica) seed powder at 50 mg/kg soil, green mould (Trichoderma harzianum) at 50.0 ml/kg soil, rhizobacteria (Pseudomonas fluorescens) at 50.0 ml/kg soil against root-knot nematode,Meloidogyne incognita-wilt fungus,Fusarium oxysporum disease complex on green gram,Vigna radiata cv ML-1108. All the treatments significantly improved the growth of the plants as compared to untreated inoculated plants.
Analysis of data showed that carbofuran andA. indica seed powder increased plant growth and yield significantly more in comparison to bavistin andP. fluorescens. Carbofuran was highly effective against nematode, bavistin against fungus,A. indica seed powder against both the pathogens and both the bioagents were moderately effective against both the pathogens. 相似文献
Angular momentum carried by a classical circularly polarized electromagnetic plane wave (light) appears to be identically
zero inasmuch as its linear field-momentum density is directed along wave propagation, and, therefore, the angular momentum,
being the integrated moment of the linear momentum density about an axis parallel to the direction of propagation, necessarily
vanishes — in detail. This, however, contradicts the established fact that circularly polarized light does carry angular momentum
that remains classically non-zero. The paradox is resolved in a physically transparent manner by treating this problem as
that of a transversely bounded, and hence necessarily non-trans verse, electromagnetic wave propagating along a circular waveguide,
in the limit as its radius tends to infinity. We get a non-zero angular momentum that bears the correct ratio to wave energy.
This angular momentum derives essentially and exactly from the boundary conditions for the geometry considered. This is an
interesting example of surface terms giving a volume (bulk) contribution, much as in the entirely different context of orbital
diamagnetism, which was regarded as a surprise of theoretical physics by Rudolf Peierls.[1] 相似文献
Purpose: The purpose of this study is to develop a conceptual framework with related analysis methodologies that identifies the influence of social environment on an established cropping system.
Design/methodology/approach: A stratified survey including 103 villages and 823 farmers was conducted in all districts of Haryana (India). Firstly, technical efficiency (TE) was modeled using biophysical data including grain yield, seeding rate, wheat varieties, tillage, sowing date, seed source, harvesting method and the application of fertilizer, herbicide and irrigation. The relationship between TE and social community factors such as farm size, farmer age, level of education and agricultural support programs was analyzed by regression tree.
Findings: TE was lower with the farmers who only have education to a primary standard. Farmers with high TE scores were mostly between 35 and 40 years of age, and a higher TE association was common for farmers who use technical publications. Social individual factors such as farmers’ views on the future of farming were also analyzed across different TE levels.
Practical implications: Farmers with lower TE are an obvious target for production improvement, particularly given the understanding that the overall production yield gap is small in Haryana.
Theoretical implications: Our conceptual framework shows a quantitative way to establish the socio-ecological linkage, and to identify the opportunities for changes in management with extension services leading to productivity improvement.
Originality/value: This paper provides a novel framework with detailed methodology to effectively identify the socio-economic factors that limit the biophysical production in an agricultural system. 相似文献
This qualitative inquiry investigates postgraduate students’ conceptions of research methodology and how it contributes to their learning. It explores factors likely to motivate student choice of research methodology and challenges in understanding research methods. The research was carried out at research-intensive universities in New Zealand and in Malaysia with similar postgraduate programmes. Participants were enrolled in Masters and Ph.D. programmes. Findings revealed that participants share a recognition that research methodology is a significant body of knowledge in postgraduate education. However, there were noticeable differences in perspectives regarding what constitutes research methodology and whether or not it should be conceived as a discipline. To some participants, learning research methodology is less of a discipline but rather an acquisition of a set of isolated facts and skills without necessarily acquiring a deeper understanding of research. Furthermore, postgraduate students choose research methodology based on a number of factors such as familiarity with a method, methodological orientation of the primary supervisor, the domain of study, and the nature of research problems pursued. Participants reported that the key challenges they face in understanding research methodology include framing research questions, understanding the theory or literature and its role in shaping research outcomes, and difficulties in performing data analysis. 相似文献
