The Relationship

<p class="3">Online instructors need to avoid unclear and confusing explanations of content, which can reduce the quality of learning. Extraneous load is reflective of poor instruction, in that it directs student effort towards processing information that does not contribute to learning. However, students may be able to manage poor instruction through effort regulation. Students who show high levels of effort have been shown to overcome poor instruction in some cases. This study analyzed survey responses from South Korean university students studying online (n = 1,575) to examine the relationship between self-regulated effort and germane load within varying extraneous load conditions. The experimental design separated extraneous load responses into three conditions (low, medium, high). Within each extraneous load condition, self-regulated effort responses were also separated (low, medium, high). The results showed that as extraneous load increased, self-regulated effort had a weaker relationship with germane load. It was also found that the use of effort regulation is effective only when dealing with low and mid-level extraneous load situations and that use of such strategies within high extraneous load situations was not effective. These results show the importance of improving instruction to reduce extraneous cognitive load, in that, not even high levels of effort can overcome poor quality instruction.</p>

Purpose Due to the autonomous nature of e-learning, learner control options should be provided to allow students to be more selective of content based on learning needs. Maintaining students’ situational interest should also be a goal in e-learning, as research shows that doing so leads to a greater chance of success. The purpose of this paper is to investigate the relationship between learner control and maintained situational interest in hopes of promoting better engagement through content selection based on learning needs. Design/methodology/approach This study analyzed survey responses from university students (n = 2,173) participating in a variety of massive online courses in South Korea to investigate the correlation between system-provided learner control and maintained situational interest. Additionally, the correlation between learner control and maintained situational interest was examined among demographic subsets including gender, age and grade level. Findings Results show a positive relationship between learner control and maintained situational interest, as well as a positive relationship between learner control and maintained situational interest among each demographic subset. Originality/value These results add to the current literature by promoting a practical way of maintaining students’ situational interest by providing them with the ability to control aspects of their own learning processes.

Abstract Motivation R Experiment objects such as the SummarizedExperiment or SingleCellExperiment are data containers for storing one or more matrix-like assays along with associated row and column data. These objects have been used to facilitate the storage and analysis of high-throughput genomic data generated from technologies such as single-cell RNA sequencing. One common computational task in many genomics analysis workflows is to perform subsetting of the data matrix before applying down-stream analytical methods. For example, one may need to subset the columns of the assay matrix to exclude poor-quality samples or subset the rows of the matrix to select the most variable features. Traditionally, a second object is created that contains the desired subset of assay from the original object. However, this approach is inefficient as it requires the creation of an additional object containing a copy of the original assay and leads to challenges with data provenance. Results To overcome these challenges, we developed an R package called ExperimentSubset, which is a data container that implements classes for efficient storage and streamlined retrieval of assays that have been subsetted by rows and/or columns. These classes are able to inherently provide data provenance by maintaining the relationship between the subsetted and parent assays. We demonstrate the utility of this package on a single-cell RNA-seq dataset by storing and retrieving subsets at different stages of the analysis while maintaining a lower memory footprint. Overall, the ExperimentSubset is a flexible container for the efficient management of subsets. Availability and implementation ExperimentSubset package is available at Bioconductor: https://bioconductor.org/packages/ExperimentSubset/ and Github: https://github.com/campbio/ExperimentSubset.

The Relationship

Recent studies have shown that trusting attitudes and behavior are biologically influenced. Focusing on the classic trust game, it has been demonstrated that oxytocin increases trust and that humans are endowed with genetic variation that influences their behavior in the game. Moreover, several studies have shown that a large share of the variation in survey responses to trust items is accounted for by an additive genetic component. Against this backdrop, this article makes two important contributions. First, utilizing a unique sample of more than 2,000 complete Swedish twin pairs, we provide further evidence of the heritability of social trust. Our estimates of the additive genetic component in social trust were consistent across the sexes – .33 for males and .39 for females – and are similar to the results reported in earlier studies. Secondly, we show that social trust is phenotypically related to three psychological traits – extraversion, personal control, and intelligence – and that genetic factors account for most of these correlations. Jointly, these psychological factors share around 30% of the genetic influence on social trust both for males and females. Future studies should further explore the possible causal pathways between genes and trust using panel data on both psychological traits and social trust.

AbstractThe present study aimed to determine the genetic and environmental etiology of the association between childhood negative emotionality (NE) and hyperactivity/inattention problems (HIP) using South Korean elementary school twins (mean age = 10.19 years, SD = 1.79 years). Telephone interviews were given to mothers of 919 twins (229 monozygotic males: 112 pairs and 5 individuals; 148 dizygotic males: 73 pairs and 2 individuals; 180 monozygotic females: 87 pairs and 6 individuals; 103 dizygotic females: 50 pairs and 3 individuals; 259 opposite-sex dizygotic twins: 127 pairs and 5 individuals) to assess their children’s NE and HIP. Consistent with prior studies, the phenotypic correlation between NE and the HIP was moderate (r = .29; 95% CI = .24, .34). Model-fitting analysis revealed that additive genetic and nonshared environmental influences on NE were .45 (95% CI [.34, .54]) and .55 (95% CI [.46, .66]), respectively, and that additive and nonadditive genetic, and nonshared environmental influences on HIP were .08 (95% CI [.03, .26]), .41 (95% CI [.21, .51]) and .51 (95% CI = .42, .61), respectively. In addition, the additive genetic correlation between NE and HIP was 1.0 (95% CI [.52, 1.00]), indicating that additive genetic factors are entirely shared between the two phenotypes. Nonadditive genetic influences were unique to HIP and not responsible for the NE-HIP association. Nonshared environmental correlation was significant but modest (re = .18, 95% CI [.06, .30]).

Abstract Based on strategic human capital theory, this study examines the effects of star surgeons on two different types of healthcare outcomes (i.e., number of surgical patients and length of patients’ in-hospital stay after surgery) in the surgery department. We also explore whether the relationship between star surgeons and healthcare outcomes is contingent on the expertise disparity between star and non-star surgeons. The results of an empirical analysis on colorectal cancer surgeons in 80 departments in South Korean hospitals show that the number of star surgeons increases the number of surgical patients and reduces the length of patients' stay after surgery. Moreover, the positive relationship between star surgeons and the number of surgical patients is strengthened when the expertise disparity between star and non-star surgeons is low. The implications of these findings for research and practice are also discussed.

There is emerging evidence that new technologies are related to improvements in productivity. Nevertheless, in considering the relationship between new technology and productivity, it is vital to consider human resource management and development issues due to their mediating effects on the relationship between new technology and productivity. This paper focuses on training technologies, especially e‐learning. The increasing use of new technologies to deliver training and to store and communicate knowledge means that trainers must be technologically literate. That is, they must understand the strengths and weaknesses of new technologies and implementation issues such as overcoming users’ resistance to change. The paper reports the findings of a study of 724 Lithuanian employees, which revealed relatively weak usage of new technologies and e‐learning in human resource development processes.
