Value Measurement

This study aims to develop cross-cultural value measurement scales that can overcome established methodological problems and test the dimensional frameworks of the scale with non-Asian respondents. It applies a mixed-method approach to observe intrinsic, nationally distinct values, and develop a generalized values measurement scale. This study found new value dimensions that were not present in the previous value studies (i.e., life balance, emotional growth, family union, and friendship) and provided segmented subdimensions (i.e., balancing between work and rest, time management, rewards of investment, and self-examination). This complements and enhances the current body of knowledge on value measurement.

We assessed the effects of resistance circuit-based training (CT) on strength, cardiorespiratory fitness, and body composition. A systematic review with meta-analysis was conducted in three databases, ending on March, 2020. Meta-analysis and subgroup analysis were used to analyze the effects of pre–post-intervention CT and differences from control groups (CG). Of the 830 studies found, 45 were included in the meta-analysis (58 experimental groups (n = 897) and 34 CG (n = 474)). The CT interventions led to increases in muscle mass (1.9%; p < 0.001) and decreases in fat mass (4.3%; p < 0.001). With regard to cardiorespiratory fitness, CT had a favorable effect on VO2max (6.3%; p < 0.001), maximum aerobic speed or power (0.3%; p = 0.04), and aerobic performance (2.6%; p = 0.006) after training. Concerning strength outcome, the CT increased the strength of the upper and lower extremities. Only the magnitude of strength performance appears to be influenced by the training (number of sessions and frequency) and the training status. Moreover, low and moderate intensities and short rest time between exercise increase the magnitude of change in fat mass loss. Therefore, CT has been shown to be an effective method for improving body composition, cardiorespiratory fitness, and strength of the lower and upper limbs.

Sensorimotor Performance

Inpatient rehabilitation has been shown to be an effective intervention for sensorimotor performance in multiple sclerosis (MS) patients. So far, predictions of the rehabilitation outcomes are limited. The objective was to predict inpatient rehabilitation outcomes by changes in the Watzmann Severity Scale (WSS), a statistical estimation of the EDSS by sensorimotor capacity. Sensorimotor performance and physical activity during rehabilitation (by actigraphy) were assessed in a sample of 28 MS patients at a facility for neurorehabilitation. Daily changes in the WSS were predicted by a model of multiple linear regression. The resulting model had an R2adjusted of 0.48 (p < 0.01) and revealed five impacting factors (a reduction in the WSS represents an improvement): the number of steps (β-weight = 0.52, p < 0.01), the duration of nocturnal rest time (β-weight = 0.46, p = 0.01), the EDSS at entry (β-weight = 0.38, p = 0.03), a relapsing-remitting MS (β-weight = 0.37, p = 0.03), and the performance in a visuomotor pursuit task with time pressure (β-weight = −0.35, p = 0.04). One standard deviation improvement was predicted when the patient at admission yielded 6600 fewer steps per day, 94 min less rest per night, −2.7 points in the EDSS at entry, a relapsing-remitting MS, and a pursuit task performance that decreased by 2.2 standard deviations. Overall, the patients improved by −0.22 ± 0.51 WSS points during 19.3 ± 4.5 d of inpatient rehabilitation. Different potential explanations of the findings are discussed, one of which proposes that the results reflect an unhealthy lifestyle which, in addition to MS, would explain the higher predicted improvements by rehabilitation tackling both MS and the patients’ lifestyle.

In electrified vehicle applications, understanding the battery characteristics is of great importance as it is the state-of-art principal energy source. The key battery parameters can be identified by one of the robust and nondestructive characterization techniques, such as electrochemical impedance spectroscopy (EIS). However, relaxing the battery cell before performing the EIS method is crucial for the characterization results to be standardized. In this study, the three most common and commercially available lithium-ion technologies (NMC/graphite, LFP/graphite, NCA/LTO) are investigated at 15–45 °C temperature, in the range of 20–80% state of charge (SoC) and in fresh and aged state of health (SoH) conditions. The analysis shows that the duration of the relaxation time before impedance measurement has an impact on the battery’s nonlinear behavior. A rest time of 2 h can be proposed, irrespective of battery health condition, considering neutral technology-based impedance measurement. An impedance growth in ohmic and charge transfer characteristics was found, due to aging, and the effect of rest periods was also analyzed from an electrochemical standpoint. This experimental data was fitted to develop an empirical model, which can predict the nonlinear dynamics of lithium technologies with a 4–8% relative error for longer rest time.

The effect of transport on serum amyloid A (SAA), haptoglobin (Hp), Fibrinogen and white blood cells (WBC) was evaluated in 10 ewes and 10 beef cattle. All animals were transported by road for 6 h over a distance of about 490 km with an average speed of 80 km/h. Blood samples, collected via jugular venepuncture, were obtained before and after transport as well as after 12, 24 and 48 h rest time. One-way repeated measures analysis of variance showed a statistically significant effect of sampling time on SAA, Hp, and WBC in ewes and beef cattle. Based on these results, Hp and SAA levels, together with WBC, may be useful indicators of animal health and welfare and in predicting the risk assessment in meat inspection.

PurposeThe raising of grandchildren by grandparents is a global phenomenon, and it is common in Indonesia. This is because parents are often unable or unwilling to raise their own children. However, the debate around “grandparenting” is still limited in Indonesia. The purpose of this paper is to gain a better understanding of the experience and views of grandparents on “grandparenting.”Design/methodology/approachThe methodology employed was qualitative and informed by phenomenology. The authors conducted in-depth interviews with 13 grandparents who were raising their grandchildren who were under five years old. The data were analyzed using thematic content analysis.Findings5 main themes and 13 subthemes emerged from the analysis of the data. The themes were responses, strategies for overcoming negative responses, the grandparents’ role, the reason for raising grandchildren, and the cultural aspect of “grandparenting” in Java. All of the grandparents enjoyed their roles as grandparents. They felt that they helped fulfill their grandchildren’s physical and educational needs.Social implicationsThe experience of raising a grandchild can be both positive and negative, depending on the cultural aspects in the Java and the family as a whole system. Grandparents require healthcare and informal support to maintain their well-being.Originality/valueThis paper provides new insights into “grandparenting” closely related to social and cultural aspect within the community. Grandparents enjoy being a part of the Javanese tradition. The supportive role of grandparents in Indonesia is important. However, older adults need to balance the role of “grandparenting” and rest time so that they remain healthy and happy.

This paper aims toinvestigatethe risk of physical fatigue at different levels of posture and repetition during manual handling task. Ten subjects with nohistoryof musculoskeletal disorders performed manual handling tasks at three levels of posture and two levels of repetition. The task completion time is recorded during the experimental task and the subjects rated their perceived discomfort level after the task completion. The results indicated that the lower posture of hand at higher repetition resulted in higher perceived discomfort level that leads to higher risk of physical fatigue. The higher repetition requires higher rest time for recovery and required lengthy completion time. The findings of this study served as a reference to the manufacturing industry in manual handling task design and planning to mitigate issues related to work-related physical fatigue at different levels of posture and repetition that could lead to the risk of work-related musculoskeletal disorders (WMSDs)
