Studies using a triaxial accelerometer and heart rate (HR) simultaneously for estimating energy expenditure (EE) during uphill exercise are rare. Exploring the optimal location for placing the accelerometer for predicting EE during uphill exercise is essential. Sixteen healthy male participants (M ± SEM; age 25.00 ± 0.61 years; body weight 74.13 ± 2.51 kg; body height 1.74 ± 0.01 m; body mass index 24.30 ± 0.63 kg/m2) exercised on a treadmill under 12 conditions (4 speeds and 3 gradients) on 3 days. Triaxial accelerometers, an HR recorder, and a metabolic measurement system were simultaneously used. Accelerometer outputs from various anatomical locations (upper arm, chest, lower back, waist, thigh, and instep) showed significant positive correlations with EE (0.819, 0.846, 0.816, 0.820, 0.672, and 0.669, respectively; p < .05). The linear regression equation for changes in HR showed the highest coefficient of determination (r2) of .837 with 87.9% reliability. When the HR signal was included, the r2 value (> .842) and reliability (87.9%) between the accelerometer outputs and EE improved. Accelerometer outputs from the waist position alone provide highly accurate EE values. Using both accelerometer outputs and HR for EE estimation during uphill exercise is feasible and improves the accuracy of EE prediction.  相似文献

The literature is inconclusive about the positive and negative effects of performance approach goal orientation (PAGO) (i.e., a focus on demonstrating high performance and outperforming others) on creativity. To address this issue, this study examines when and how PAGO stimulates or hinders employee creativity. Drawing on trait activation theory and a self‐regulatory perspective, we propose that outcome instrumentality (i.e., the perception that one will receive desired organizational outcomes when performing well) moderates the effects of PAGO on task persistence bidirectionally, which, in turn, facilitates or hinders employee creativity. Results based on a two‐wave, multi‐source field survey provided strong support for our hypotheses. We found that the relationship between PAGO and task persistence was positive when outcome instrumentality was high but became negative when outcome instrumentality was low. Moreover, we found a moderated mediation effect, such that the indirect effect of PAGO on creativity through task persistence was positive when outcome instrumentality was high but negative when outcome instrumentality was low. These findings extend the PAGO literature by elucidating the goodness and badness of PAGO and provide practical implications on how to manage performance approach‐oriented employees to capitalize on their creative potentials and minimize the possible detrimental effects of PAGO on creativity.  相似文献

先前关于归纳推理的研究没有探讨过图形类别归纳任务中决策过程的事件相关电位(ERPs)特征。该研究采用图形材料,通过记录和分析图形类别归纳推理任务的结论评估阶段的脑电信号,探讨了不同类别条件下图形归纳推理决策过程的ERP特征。实验结果显示,推理决策过程中,当前提为一些狗具有某种属性特征时,结论一致类别(狗类及马类)比结论不一致类别下(椅子类)的归纳推理诱发了更大的P3b的波幅; 而结论一致类别下,类别内(狗类)比类别外(马类)推理诱发更大的后部脑区的P3b的波幅,反映了相似性对类别归纳的贡献。该研究为理解类别归纳过程的决策阶段的动态加工过程提供了神经电生理学证据。研究结果进一步支持了类别归纳的相似性理论模型。  相似文献

通过考察编码阶段注意分心对定义一体化条件下联结记忆成绩的影响,探究定义一体化编码对注意资源的依赖程度。使用注意分心范式,在记忆编码过程操作无分心、奇偶分心和大小分心条件,比较不同注意条件下的联结记忆成绩。结果发现:与无分心条件相比,定义一体化下的联结记忆成绩在两种分心条件下没有显著变化,而造句下的联结记忆成绩在两种分心条件下显著降低。当前发现表明了定义一体化编码较少依赖于注意资源,这深化了对定义一体化编码机制的认识。  相似文献

腐败是危害社会公正、法治的不良现象。为考察中国文化中的人情对腐败意图的影响,通过两轮问卷向190名大学生进行调查,结果发现:(1)人情不是单一整体,而是包含情感、资源、规范三个维度的复杂构念;(2)人情中的资源维度显著正向影响腐败意图,并且这一过程不受道德认同的影响。研究结果说明,为建立一个清廉、和谐的社会,人情中的不良成分,如利用人情资源获得优先对待必须被避免。  相似文献

A father of a child with cancer experiences psychological stress related to his child’s cancer diagnosis and treatment, which may affect his relationship with his spouse. Nevertheless, little attention has been paid to how having a child with cancer affects the marital relationship from the perspective of the father. We examined the impact of the child’s cancer on the father’s relationship with his spouse in Korea. We conducted in-depth interviews with 20 fathers (mean age?=?41.35 years; SD?=?4.49) of children who were diagnosed with cancer before the age of 19 and were within 5 years of the diagnosis. The mean age of the child with cancer was 9.1 years (SD?=?3.68), and the mean age at diagnosis was 6.4 years (SD?=?4.08). The analysis of the interviews revealed the following four themes (and eight subthemes): conflicts between spouses (lack of father’s participation in caregiving, financial and work-related stress), mental suffering (heartbroken, torn between caregiving and work), change in communication (child-focused communication, avoiding communication), and change in the marital relationship (neglected relationship, new trust built in the relationship). A father’s increased conflict in the marital relationship after his child’s diagnosis of cancer was intensified by his limited involvement in child care and parenting responsibilities. An understanding of the change in the father’s relationship with his spouse can inform the development of a psychosocial intervention that may strengthen a father’s emotional intelligence and resilience, which could improve the marital relationship.  相似文献

The Eyberg Child Behavior Inventory (ECBI) has previously been shown to be a psychometrically sound instrument used to assess disruptive behaviors in children in the United States and in other cultures/countries but not in Taiwan. The purpose of this study was to examine the factor structure and to establish the discriminative validity of the ECBI with two groups of Taiwanese children: 70 clinic-referred children with clinically elevated externalizing behavior problems and 70 community-based matched comparison children. Exploratory factor analyses resulted in a six-factor model for the clinic-referred sample and a five-factStrengths and Difficultieor model for the matched comparison sample, indicating that the ECBI is not unidimensional. Adequate convergent and divergent validity also were established between the ECBI Intensity and Problem Scales and another measure of child externalizing (for assessing convergent validity) and internalizing (for determining divergent validity) behavior. The results of the present study suggest that the ECBI is a valid measure of assessing externalizing behavior problems in Taiwanese children. Future research may seek to refine the factor structure of the ECBI in a Taiwanese sample. Future studies are also needed to examine other psychometrics of the ECBI, replicate this study with a larger sample, and establish its normative data in Taiwan.  相似文献

The present research examined the consequences of telling young children they have a reputation for being smart. Of interest was how this would affect their willingness to resist the temptation to cheat for personal gain as assessed by a temptation resistance task, in which children promised not to cheat in the game. Two studies with 3‐ and 5‐year‐old children (total N = 323) assessed this possibility. In Study 1, participants were assigned to one of three conditions: a smart reputation condition in which they were told they have a reputation for being smart, an irrelevant reputation control condition, or a no reputation control condition. Children in the smart reputation condition were significantly more likely to cheat than their counterparts in either control condition. Study 2 confirmed that reputational concerns are indeed a fundamental part of our smart reputation effect. These results suggest that children as young as 3 years of age are able to use reputational cues to guide their behavior, and that telling young children they have a positive reputation for being smart can have negative consequences.  相似文献

The present study aimed to investigate the prevalence of fatigue and determine factors associated with fatigue in female medical personnel. Based on a cross-sectional study, a total of 1608 female medical personnel at 54 hospitals in Zhuhai, China were recruited by a multistage stratified cluster sampling method. The Symptoms Checklist-90-Revised and Chalder Fatigue Scale were used to assess psychiatric symptoms and fatigue, respectively. Data regarding demographic, health, and work related variables were also collected. Multivariate logistic regression model was constructed to determine the influencing factors of fatigue. Approximately 83% of participants had experienced fatigue in the past week. The risk of fatigue was higher in aged 30–39 years old than older or younger participants; Longer sleeping time predicted a lower prevalence of fatigue (OR = .35), while tense physician-patient relationship predicted a higher prevalence of fatigue (OR = 1.77). Depression (OR = 1.76) and anxiety (OR = 1.96) were found related to fatigue. Additionally, fatigue was associated with marital status, occupation, health related factors (exercise, regular diet, and health status), and work related factors (hospital rank and turnover intention). These study findings might facilitate development and implementation of targeted interventions and preventive measures.  相似文献
