This study investigated three controversial issues regarding frame of reference training (FOR), a type of rater training: (1) Does it improve behavioral recall, (2) Can it be improved by incorporating behavior observation training (BOT), and (3) Can its effects persist over time? Results suggested that even though FOR training increases the number of behaviors recalled, it does not necessarily improve the quality of the recalled behaviors, but a combined FOR + BOT program does improve recall quality. Lastly, results suggested that FOR training can improve rating accuracy, even after a two‐week delay between rater training and the rating task.  相似文献

In recent years, training has shifted towards a more learner‐centred perspective. At the same time, rapidly changing workplaces emphasize the importance of self‐regulatory processes in the workplace. In the light of these trends, this research investigates the role of self‐regulated learning in training effectiveness. A theoretical model in which self‐regulated learning plays a central role in training evaluation was developed and validated using the structural equation method with a sample of 137 individuals. The results indicate that self‐regulated learning mediates the relationship between training climate and both transfer motivation and training evaluation. These findings indicate that the concept of self‐regulated learning plays a key role in the relationship between training context variables and organizational outcomes and offer new insights into the way organizations can improve training effectiveness.  相似文献

Self‐efficacy is clearly important for learning. Research identifying the most important sources of self‐efficacy beliefs, however, has been somewhat limited to date in that different disciplines focus largely on different sources of self‐efficacy. Whereas education researchers focus on Bandura's original sources of enactive mastery, vicarious experience, verbal persuasion and negative emotional arousal, organizational researchers focus on learning, performance prove and performance avoid achievement goal orientations. To date, however, little research has examined the importance of a specific set of self‐efficacy sources after fully accounting for the influence of other sources. Data were obtained from 278 adult trainees who completed online Microsoft Excel training. Results suggest that once accounting for achievement goal orientation, Bandura's sources of vicarious experience and negative emotional arousal are still important contributors to pretraining self‐efficacy beliefs. As such, organizations seeking to maximize training effectiveness may wish to consider pretraining interventions simultaneously targeting achievement goal orientation, vicarious experience and negative emotional arousal.  相似文献

The performance of maltodextrin gel as a replacement (25%, 50%, 75% and 100%) for shortening along with sucrose and high fructose corn syrup‐90 (HFCS‐90), adjusted for sweetness in each treatment, was evaluated in a high‐ratio white‐layer cake formulation. Two controls were used as a reference to fat‐replaced cakes: control A (100% fat and 100% sucrose) and control B (100% fat with 50% sucrose/50% HFCS‐90), which closely matched the sugar system of the fat‐replaced cakes. Volume of cakes showed that treatment F (100% fat‐substituted) was significantly (P < 0.05) different from the other treatments. Crust and crumb L‐ and b‐values indicated that control B produced a dark crust (P < 0.05) with a light crumb (P < 0.05) whereas treatment E (75% fat substituted) produced a light crust (P < 0.05) and treatment F a darker crumb (P < 0.05) with a significantly (P < 0.05) higher moisture content. Degree of staling significantly (P < 0.05) increased over time for all treatments. Sensory results indicated that treatment F produced a significantly (P < 0.05) moister, less adhesive and cohesive cake. Tenderness and sweetness scores indicated that treatments E and F were significantly (P < 0.05) tougher and less sweet, respectively, when compared with the other treatments. Results from both the physical and sensory analyses indicated that the combination of maltodextrin gel up to a 75% reduction for shortening and sucrose/HFCS‐90 resulted in satisfactory cakes.  相似文献

This study seeks to address the disagreement in the literature about compulsive buying behaviour's (CBB) dimensional structure and tests for cross‐cultural and cross‐gender invariance in young British, Chinese, Czech and Spanish consumers using structural equation modelling. The results show that CBB has two compulsive dimensions: Compulsive Purchasing (CP) and Self‐control Impaired Spending (SIS). These dimensions are cross‐culturally invariant, although the influence of SIS on CBB is higher in more developed countries, particularly among females. The confirmation of the SIS dimension and the external validity of the CBB construct established through the cross‐cultural invariance in CBB dimensions indicate that screening tools should be revised accordingly. The SIS dimension has possibly been previously misinterpreted as impulsive and/or as spontaneous buying and may explain the higher incidence of CBB among female consumers.  相似文献

Despite the effectiveness of on‐the‐job training (OJT), few systematic empirical studies have been conducted on how OJT trainers instruct trainees in firms. The primary goal of this study was to investigate the characteristics of the trainer's instructional skills for OJT using survey data collected from 715 employees covering 22 firms. Results indicate that excellent OJT trainers use four types of instructional skills: (1) stretching trainee objectives, (2) monitoring their progress, (3) providing positive feedback, and (4) promoting reflection on results. The findings suggest that excellent OJT trainers facilitate trainees' experiential learning by promoting deliberate practice and reflective practice. Theoretical and managerial implications are also discussed.  相似文献

The purposes of the present investigation were to attempt to replicate the negative effects for learning prompts in older adults reported by Cavanagh, Kraiger and Peters (2016), determine if the impact of learning prompts depends on type of prompt, and investigate the two possible explanations of the negative impact of prompts – increased cognitive load and higher negative affect. Learning prompts refer to short text inserted into training content to encourage trainees to rehearse new content or engage in meta‐cognitive activity. Although learning prompts generally lead to greater learning in training, Cavanagh et al. reported a negative impact for prompts on measures of recall and transfer. Using similar training materials and learning outcome measures, we conducted two studies using both elaboration and meta‐cognitive prompts in online training. In the first, older adults (N = 194) between 55 and 70 years and younger adults (N = 218) were randomly assigned to either a meta‐cognitive, elaboration or no prompts (control) condition. Older adults learned less and reported greater mental effort than younger learners, but these effects were not moderated by prompt condition. In the second, N = 57 older adults were randomly assigned to the same three prompts conditions listed above. Older adults learned less with prompts than without, but there were no differences between conditions in mental effort or negative affect. In sum, we found negative effects for learning prompts in older adults in two studies, but found no evidence to suggest that these effects were due to either increased cognitive load or greater negative affect.  相似文献

Based on the theory of absorptive capacity, this study examines the following question. In the context of cross‐cultural training, can the amount of previously accumulated cultural knowledge affect the ability of a trainee to absorb further learning about a new culture, thus enhancing total knowledge and presumably cross‐cultural adjustment? In‐country cross‐cultural training was hypothesized to be more effective when the training components are divided and the sessions are distributed over time – resulting in increased cultural knowledge and greater cross‐cultural adjustment. Results from an experimental design suggested that in‐country cross‐cultural training can increase cultural knowledge, when distributed over time. The results also suggested that the training group had greater differences between pre‐training and post‐training scores on cross‐cultural adjustment, but the differences were not statistically different. The results, methodology and conclusions can be generalized to a variety of populations (e.g. international managers and expatriates) and organizations (e.g. multinationals). For international managers and expatriates, the results showed that in‐country cross‐cultural training, like predeparture cross‐cultural training, is also a viable intervention for knowledge acquisition.  相似文献

Bollerslev's ( 1990 , Review of Economics and Statistics, 52, 5–59) constant conditional correlation and Engle's (2002, Journal of Business & Economic Statistics, 20, 339–350) dynamic conditional correlation (DCC) bivariate generalized autoregressive conditional heteroskedasticity (BGARCH) models are usually used to estimate time‐varying hedge ratios. In this study, we extend the above model to more flexible ones to analyze the behavior of the optimal conditional hedge ratio based on two (BGARCH) models: (i) adopting more flexible bivariate density functions such as a bivariate skewed‐t density function; (ii) considering asymmetric individual conditional variance equations; and (iii) incorporating asymmetry in the conditional correlation equation for the DCC‐based model. Hedging performance in terms of variance reduction and also value at risk and expected shortfall of the hedged portfolio are also conducted. Using daily data of the spot and futures returns of corn and soybeans we find asymmetric and flexible density specifications help increase the goodness‐of‐fit of the estimated models, but do not guarantee higher hedging performance. We also find that there is an inverse relationship between the variance of hedge ratios and hedging effectiveness. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 30:71–99, 2010  相似文献

The short‐time asymptotic behavior of option prices for a variety of models with jumps has received much attention in recent years. In this work, a novel second‐order approximation for at‐the‐money (ATM) option prices is derived for a large class of exponential Lévy models with or without Brownian component. The results hereafter shed new light on the connection between both the volatility of the continuous component and the jump parameters and the behavior of ATM option prices near expiration. In the presence of a Brownian component, the second‐order term, in time‐t, is of the form , with d2 only depending on Y, the degree of jump activity, on σ, the volatility of the continuous component, and on an additional parameter controlling the intensity of the “small” jumps (regardless of their signs). This extends the well‐known result that the leading first‐order term is . In contrast, under a pure‐jump model, the dependence on Y and on the separate intensities of negative and positive small jumps are already reflected in the leading term, which is of the form . The second‐order term is shown to be of the form and, therefore, its order of decay turns out to be independent of Y. The asymptotic behavior of the corresponding Black–Scholes implied volatilities is also addressed. Our method of proof is based on an integral representation of the option price involving the tail probability of the log‐return process under the share measure and a suitable change of probability measure under which the pure‐jump component of the log‐return process becomes a Y‐stable process. Our approach is sufficiently general to cover a wide class of Lévy processes, which satisfy the latter property and whose Lévy density can be closely approximated by a stable density near the origin. Our numerical results show that the first‐order term typically exhibits rather poor performance and that the second‐order term can significantly improve the approximation's accuracy, particularly in the absence of a Brownian component.  相似文献

Animated agents have the potential to increase engagement and learning during online training by acting as personalized tutors. However, little is known about the conditions that make these agents most effective. In this study, 183 e‐learners completed a Microsoft Excel training course. Approximately half were assigned an agent with predetermined features. The others were allowed to choose their agent's appearance, personality, feedback style or all of the above features. Offering multiple choices increased learning. Unexpectedly, choice of feedback style alone decreased self‐efficacy. Choosing the agent's appearance increased self‐efficacy and the number of training modules completed. Overall, this study expands the learner control literature, identifying a new form of learner control that has some beneficial effects on knowledge acquisition.  相似文献

This paper examines the determinants of job‐related training and workplace voice. Using data from a unique 2016 cross‐national survey of Australian, British, Canadian and American employees, the paper contrasts two classic formulations in the literature; (1) the neoclassical/human capital approach which predicts that individual characteristics (such as age and education) which increase the efficiency of learning, will have the largest impact on the allocation of training (i.e. younger and more educated employees will be afforded training) and (2) the traditional institutional approach which favors the structural characteristics present at the industry and firm level, the nature of the job itself and the strategic choices of firms as the major predictors of job‐related training. We find that age – a key factor in the human capital model – plays a significant role in the allocation of training but that education (in keeping with recent evidence) does not. In sum the human capital model provides, at best, only a partial explanation for the differences in training observed across individuals. In contrast, variables invoked by the institutional literature (i.e. occupation level; industry; ownership type; and market structure) are highly significant and account for a much greater proportion of the variance in training observed across workers. Other institutional factors such as the presence of a union and a human resource department were strong positive predictors of job‐related training. But most important were product‐market strategy and employee voice. Respondents working in firms utilizing a ‘high road/high quality’ product/service strategy and with a workplace consultative committee were significantly more likely to receive training than similar workers employed in observably similar firms. This last finding supports the industrial relations view of voice as an important channel by which training is optimally delivered inside the firm.  相似文献

The over‐saturated dietary supplement (DS) market in developed countries such as the US spurs the need for foreign market expansion, and the Chinese market provides a great potential for the foreign soy‐based DS industry. This study examined Chinese consumers' intention to use imported (US‐made US‐brand) soy‐based DS based on the Theory of Planned Behavior (TPB). Two alternative models were also examined in which Chinese dietary culture variables, including soyfoods favourability and dining‐out sociability, as well as their interactions with attitudes, were integrated into the TPB model. A cross‐sectional, self‐administered survey was conducted with a sample of 215 subjects (137 females; 78 males) in Shanghai, China. The TPB variables attitude, subjective norm, perceived behaviour control and behavioural intention, as well as the Chinese dietary culture variables: soyfoods favourability and dine‐out sociability were measured. Multiple linear regressions were used to analyze the three models. The statistical results indicated that all three models were statistically significant to predict intention (Model 1: R2 = 0.473, P < 0.001; Model 2: R2 = 0.505, P < 0.001; Model 3: R2 = 0.525, P < 0.001). The results also showed that attitude, perceived behavioural control, and dine‐out sociability were significant (positive) determinants of intention. Soyfoods favourability acted a significant (negative) moderator of the relationship between attitude and intention. Subjective norm had no significant impact on intention. In conclusion, the TPB model was useful to predict Chinese consumers' intention to use imported soy‐based DS, but not all the TPB components weighed significantly in exploring DS consumption in China. The selected Chinese dietary culture variables were much more important predictors than subjective norm. This study makes a significant contribution in the application of the TPB model and in market strategy development for imported dietary supplements in China.  相似文献

The article reports the findings of a national evaluation study conducted in 1998 of the contribution of competency‐based training (CBT) to outcomes in vocational education and training in Australia. The study found that CBT has made significant contributions to employers, its main benefit being that learning can be achieved on‐the‐job. Thus the key advantage for enterprises is relevant training where relevance means ‘specific skills for specific jobs’. The conclusion is drawn that three key issues in relation to the practice of competency training in Australia need to be addressed: (i) recognition of the role of the expert practitioner in augmenting, and thus improving, CBT; (ii) recognition of the limitations of CBT with regard to the provision of knowledgeable skill; and (iii) recognition of the importance of defining learning in terms of outcomes and process.  相似文献

School is a major area for providing young people with nutritional knowledge and skills. In Northern Ireland home economics (HE) is taught to 11‐ to 12‐year‐olds. The 1988 Education Reform Act introduced the national curriculum and HE as a subject was effectively abolished in English schools, and key stage 3 pupils in England are taught nutrition in Science, Design and Technology and in the cross curricular theme of health education. The aim of the study was to compare the attitudes and nutritional knowledge of children in Merseyside, England (M) and Northern Ireland (NI). A questionnaire was designed, which examined attitudes to aspects of healthy eating and tested the subject's knowledge, practical and theoretical, on nutrition and healthy eating. Subjects aged 11–12 years were recruited (M: 541, NI: 128). The majority ‘understood and knew what to eat to have a healthy diet’, ‘liked the taste of healthy food’ and considered that ‘there were healthy foods at home’. However, a significantly greater number in Merseyside agreed that ‘their health will be affected in the future by what they eat now’ (M: 71%, NI: 54%, P < 0.01) and agreed that ‘they enjoyed cooking’ (M: 76%, NI: 56%, P < 0.01). Whereas more from Northern Ireland agreed that ‘they do not know what foods to eat to have a healthy diet’ (M: 14%, NI: 30%, P < 0.01), ‘that healthy eating involved “dieting” ’ (M: 29%, NI: 59%, P < 0.01) and agreed that ‘there are no healthy food choices at school’ (M: 23% NI: 42%, P < 0.01). More subjects from Merseyside disagreed that ‘healthy eating is a waste of time’ (M: 87%, NI: 77%, P < 0.01). The mean knowledge scores (correct answers) from Merseyside were significantly greater than from Northern Ireland (total score: M: 51%, NI: 43%P < 0.05; practical score: M: 58%, NI: 49%P < 0.05, theory score: M: 38%, NI: 31%, P < 0.05). The results indicate that the healthy food message seems to have been better learnt by children in Merseyside but results of surveys in Merseyside into eating habits suggest that many have not put this knowledge into practice.  相似文献

This article focuses on consumers’ unconscious counter‐reactions to incidentally received advertising appeals. Recipients can be influenced automatically by incidental ad exposure due to evaluative conditioning processes, mere‐exposure effects, or priming events. However, it is assumed that such processes, especially priming events, can also lead to automatic counter‐reactions. To test this assumption experimentally, the type of ad exposure was systematically varied between focused, incidental, and control. Among other variables participants’ response latencies to consumption‐critical word pairs in comparison to neutral pairs were measured to assess the ability to counter‐react received advertising information. Response latencies were considerably lower in the focused and incidental test conditions than they were in the control group. Since participants in the incidental group were only able to analyze the ads preattentively, results indicate an automatic activation of consumption‐critical motives or cognitions—critical associations were more available here. Thus, results provisionally support the underlying hypothesis.  相似文献

The article examines the perceptions of managers, academics and technical staff in relation to the transfer of training resulting from their participation in out‐country training funded by Bhutan's Ministry of Education. Out‐country training refers to in‐service education, training and professional development programs, especially in relation to technical education, higher education and specialization courses undertaken abroad. The objective was to evaluate the effectiveness of out‐country training over a five‐year period to gauge the level of training transfer among three different types of participants. The methodology included surveying 149 Bhutanese out‐country training participants between 1999 and 2003. A representative sampling technique was used to select 58 academics, 46 managers and 45 technical support staff for inclusion in the survey. Semistructured in‐depth interviews were also conducted with 19 of these trainees across the three categories. Results of the study indicate high initial levels of motivation in all trainees, but a change in attitude toward their training once it was underway. On return to the workplace, participants reported even less confidence in their ability to transfer their learning compared to their confidence reported before the program began.  相似文献

Guanxi facilitates interaction between companies and people in Confucian societies. Does this type of social construct still play the key role, when the entrepreneurs live in Western societies? The objective of this article is to verify the impact of Guanxi on the capacity of small and medium‐sized businesses accessing financial resources informally. To this end, data collected from small Chinese entrepreneurs active in the principal business center of Brazil were used. From nonparametric tests, the results suggest that: (1) different levels of Guanxi allow small and medium‐sized businesses to access informal financial resources; (2) different types of informal financing are mostly used, or judged to be more significant, depending on the level of Guanxi of the entrepreneur in terms of parental and nonfamily ties; and (3) unlike the Western literature on the financial cycles of start‐ups, this type of informal financing can extend beyond the initial stage of the business. © 2014 Wiley Periodicals, Inc.  相似文献

Accurate demand forecasts are critical to maintaining customer service levels and minimizing total costs, yet increasingly difficult to achieve. Using weekly point‐of‐sale (POS) and order data for 10 ready‐to‐eat cereal stock‐keeping units from 18 regional U.S. grocery distribution centers, this research empirically investigates two demand forecasting issues: (1) the accuracy of top‐down versus bottom‐up demand forecasts; and (2) whether shared POS data improve demand forecast accuracy. The results reveal a previously unexplored relationship between demand forecast methodology and the use of shared POS data. We find that the superiority of the top‐down or bottom‐up forecasting as the more accurate demand forecast method depends on whether shared POS data are used.  相似文献
