Relationship between Paternal and Maternal Parenting Style with Internet Addiction Level of Adolescents

Objective: Internet addiction has become a major problem worldwide, especially for adolescents. Adolescents are considered vulnerable and at risk of internet addiction due to the immature self-control, easy access, and flexible schedule. Parenting style has a significant influence on the incidence of internet addiction in adolescents. This study aimed to analyze the relationship between paternal and maternal parenting style toward internet addiction level of adolescents at one of junior high Schools in Surabaya, Indonesia. Method : In this cross-sectional study, a total of 114 adolescents (44 boys and 70 girls) aged ranging from 12 to 15 in a junior high school in Surabaya, Indonesia, were recruited by stratified random sampling method in November 2019. The Internet Addiction Test (IAT) and Parental Authority Questionnaire (PAQ) were used to measure internet addiction level, and maternal and paternal parenting style of adolescents. The data were analyzed using Pearson correlation and multiple regression tests with IBM SPSS Statistics 25 to adjust the relationship between paternal and maternal parenting style toward internet addiction level of adolescents. Results: a total of 77.2% of adolescents were internet addicts and the majority experienced ‘mild’ internet addiction level (52.60%). Furthermore, the Pearson correlation results indicated that paternal permissive and authoritarian parenting styles were positively correlated with internet addiction level of adolescents. The multiple regression analysis results indicated that paternal permissive parenting style significantly predicted adolescents’ internet addiction level. Conclusion: This study highlighted the significant role of paternal permissive and authoritarian parenting styles among adolescents’ internet addiction.
A new strategy to improve ramie degumming based on removal of the xylan branched structure

Ramie fiber is known as the “king of natural fibers,” and the key to its wide application is efficient and green manufacturing. Microbial degumming has gradually become a hot area of research due to its environmental protection and mild operating conditions. However, some gummy materials remain after microbial degumming. Xylan is the main component of residual gums; its acetylated branched chains create the space barrier that makes the removal of hemicellulose difficult during ramie degumming. An acetyl xylan esterase (AXE) was obtained from Bacillus pumilus and characterized to solve this problem. Its optimum temperature and pH were 35°C and 8.0, respectively, and it had good temperature and pH stability. These properties were consistent with the conditions of ramie degumming and they laid a foundation for the application of AXE in ramie degumming. Besides, an engineered strain with a high activity of AXE was constructed successfully on the basis of the wild-type degumming strain Pectobacterium carotovorum HG-49 and used for ramie degumming. The removal rate of hemicellulose and total gums by the engineered strain increased by 4.89% and 2.53%, respectively, compared with that of the wild-type strain. Moreover, the role of this AXE in ramie degumming was further proven by X-ray diffraction and scanning electron microscopy. This study showed that AXE played an important role in the removal of hemicellulose in the degumming process of ramie fibers, thus providing a promising degumming strategy for ramie and other bast fiber plants.
The outcomes of gaining digital skills for young people’s lives and wellbeing: A systematic evidence review

Research and policy have invested in the prospect that gaining digital skills enhances children’s and young people’s outcomes. A systematic evidence review of research on digital skills among 12- to 17-year-olds identified 34 studies that used cross-sectional survey methods to examine the association of digital skills with tangible outcomes. Two-thirds concerned the association with online opportunities or other benefits. Another third examined online risks of harm. Findings showed a positive association between digital skills and online opportunities, information benefits, and orientation to technology. Greater digital skills were indirectly linked to greater exposure to online risks, although any link to harm was unclear. While technical skills were linked with mixed or even negative outcomes, information skills were linked with positive outcomes. There was little research on the outcomes of communication or creative digital skills. Future research should examine the dimensions of digital skills separately and encompass a wider range of outcomes.
Transcriptional profiling of alkaline stress-induced defense responses in soybean (Glycine max)

Abstract Alkaline stress has been considered a major environmental threat to plant growth and agricultural production. Even though the mechanisms have been characterized in some plants, the information about the alkaline stress-induced defense responses in soybean is insufficient. To identify defense related genes, the transcriptional profiles of soybean seedlings were examined using RNA sequencing under alkaline stress. The results showed that a total of 4603 genes were up-regulated and 1659 were down-regulated compared to expression in control plants. Further, the functional enrichment analysis showed that these differentially expressed genes were significantly enriched in 43 pathways and mainly associated with catalytic activity and binding, metabolic process, cellular process and cell progress. Then, 19 transcription factors from AP2-EREBF, MYB families and isoflavone related genes were chosen and identified to be induced under alkaline stress by quantitative real-time polymerase chain reaction (qRT-PCR). Taken together, our results highlight the differentially expressed genes and identify a set of genes associated with the response to alkaline stress, which findings establish a foundation for further analyses of soybean alkaline stress tolerance mechanisms.

Effect of non-invasive brain stimulation on lower limb function in patients after stroke: A PRISMA-compliant systematic review and meta-analysis

Background: In recent years, it is reported that non-invasive brain stimulation [including transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS)] could improve lower limb function in patients after stroke. However, some studies showed no effect. In the present study, we aimed to make a meta-analysis to assess effect of non-invasive brain stimulation on lower limb function in patients after stroke. Methods: Studies exploring the effect of tDCS or rTMS on lower limb function in patients after stroke were searched on the PubMed, Web of Science, EMBASE, Medline, Google Scholar before March 2021. Meta-analysis was made to summarize results of these studies. Results: The present study showed significantly better walking speed, mobility and muscle strength increase effect in tDCS group compared to sham tDCS group [walking speed: standard mean difference (SMD) = 1.14, 95% CI = 0.48 to 1.80, I2 = 74.0%, p value for Q test < 0.001; mobility: SMD = 0.79, 95% CI = 0.21 to 1.36, I2 = 53.8%, p value for Q test = 0.043; muscle strength: SMD = 2.79, 95% CI = 0.61 to 4.98, I2 = 93.9%, p value for Q test < 0.001]. In addition, meta-analysis showed significantly better walking speed, balance and motor function increase effect in rTMS group compared to sham rTMS group [walking speed: SMD = 3.31, 95% CI = 1.38 to 5.24, I2 = 92.1%, p value for Q test < 0.001; balance: SMD = 3.54, 95% CI = 1.45 to 5.63, I2 = 95.4%, p value for Q test < 0.001; motor function: SMD = 1.65, 95% CI = 0.53 to 2.76, I2 = 90.3%, p value for Q test < 0.001]. Conclusions: This meta-analysis suggested that non-invasive brain stimulation improved lower limb function in patients after stroke. More large scale, blinded RCTs were necessary to confirm the effect of rTMS and tDCS on lower limb function in patients after stroke.

Variable-Scaling Rate Control for Collision-Free Teleoperation of an Unmanned Aerial Vehicle

We propose that automatically adjusting the scale factor in rate-control teleoperation could enable a human operator to better control the motion of a remote robot. In this paper, we present four new variable-scaling rate-control methods that adjust the scale factor depending on the state of the user's input commands and/or the risk of a collision between the robot and its environment. Methods that depend on the risk of a collision are designed to guarantee collision avoidance by setting the scale factor to be zero if the operator issues a command that would result in a collision between the robot and its environment. A within-subject user study was conducted to determine the effects of the four newly designed rate-control methods and a traditional fixed-scale rate-control method on a person's ability to complete a navigation task in a simulated two-dimensional environment. The results of this study indicate that well-designed variable-scale rate control can guarantee collision-free teleoperation without reducing task efficiency.
Advances in Asphaltene Petroleomics. Part 3. Dominance of Island or Archipelago Structural Motif Is Sample Dependent

Asphaltene structure is one of the most controversial topics in petroleum chemistry. The controversy is centered on the organization of aromatic cores within asphaltene molecules (single aromatic core, island and multiple aromatic core, archipelago) and specifically the inconsistency between the island model and the composition of the products derived from asphaltene pyrolysis/thermal cracking. Such products are consistent with the coexistence of island and archipelago asphaltene structural motifs. However, the archipelago model continues to lack the widespread acceptance of the petroleum community, in part due to mass spectrometry results in support of the island model. In the first and second part of this series, we demonstrated that the disproportionally high atmospheric pressure photoionization (APPI) ionization efficiency (monomer ion yield) of island species is due to weak nanoaggregation of large aromatic cores which do not extensively aggregate in toluene, whereas more archipelago-dominant fractio.
Earliest Triassic Conodonts of Gua Panjang, Merapoh, Pahang and their Bearing towards Permian-Triassic Mass Extinction in Malaysia

A single sample from the logged section at eastern side of Gua Panjang limestone hill, southwest of Kampung Kubang Rasa Village, Merapoh, has yielded 5 very important conodont species. They are Hindeodus parvus erectus, Hindeodus parvus parvus, Hindeodus latidentatus latidentatus, Hindeodus latidentatus praeparvus, Hindeodus postparvus, Hindeodus eurypge and Isarcicella staeschi. These Early Triassic conodonts were obtained in a bioclastic dolostone sample, located 2.5 m above bioclastic grainstone which yielded Late Permian foraminifera. The conodonts found were given Conodont Alteration Index (CAI) scale of 5, consistent with the heating of Main Range granitoid during Indosinian Orogeny. Limestone harbouring basal Triassic conodonts in Gua Panjang is interpreted to be deposited in an open shallow marine shelf environment.
Effect of Short T6 Heat Treatment on the Thermal Conductivity and Mechanical Properties of Different Casting Processes Al-Si-Mg-Cu Alloys

The thermal conductivity of alloys is gradually becoming appreciated. It is often assumed that heat treatment can improve the thermal conductivity of Al-Si-Mg-Cu alloys, but there has been little relevant research. This paper studies the effects of different casting processes and short T6 heat treatment (ST6) on the thermal conductivity and mechanical properties of Al-Si-Mg-Cu alloys. The results show that a microstructure with fine α-Al crystal grains can be obtained by semi-solid die casting (SSDC), improving the mechanical properties of the Al-Si-Mg-Cu alloy in the as-cast state. After SSDC, the size and aspect ratio of eutectic silicon can be reduced by ST6 treatment, effectively improving the thermal conductivity and mechanical properties of the alloy. Finally, the influence of eutectic silicon on electron transport is analyzed in detail. With the SSDC + ST6 processing technology, Al-Si-Mg-Cu alloys with excellent thermal conductivity and mechanical properties can be obtained.
Joint utilization of double-pulse laser-induced breakdown spectroscopy and X-ray computed tomography for volumetric information of geological samples

The purpose of this study is to present a novel algorithm to combine high-resolution X-ray Computed Tomography (HRXCT) and Double-Pulse Laser-Induced Breakdown Spectroscopy (DP LIBS) for geological samples' analysis. The ability to reveal the elemental composition of the internal structure is demonstrated on a rare geological sample from a unique Talnakh PGE–Cu–Ni sulfide deposit. The main point of the suggested approach is to assign the DP LIBS elemental maps to the different densities of the HRXCT data. This assignment is based on the coordinates of the HRXCT data (top-cross section) and DP LIBS elemental maps of the surface. The resolution and orientation of these two images are aligned in order to enable a comparison. Moreover, the volumetric information about individual materials within the sample was estimated.
Importance of Marketing Mix Elements in Determining Consumer Purchase Decision in the Retail Market

This research aimed to identify the linkages between marketing mix elements and the purchase decision process among consumers in the Malaysian retail industry. To fulfill this objective, the present study followed a quantitative survey for gathering the data from the consumers of department stores at the East Coast region in Malaysia. All of the obtained data were inserted and coded using SPSS and then analysed by AMOS 18. The findings indicated that the impact of advertising on the consumers' purchase decision is positive and statistically significant. Besides that, the findings demonstrated that distribution intensity has a negative effect on purchase decision, whereas price plays a key important role in affecting purchase decisions process of the consumers. Lastly, the findings of this paper verified that store image and store location have significant positive linkages with purchase decision. These outcomes enhance our understanding on the role of marketing mix elements in determining a consumer's purchase decision, particularly in the retail context.
Size Matters, but Species Do Not: No Evidence for Species-Specific Swimming Performance in Co-Occurring Great Basin Stream Fishes

For fishes, swimming performance is an important predictor of habitat use and a critical measure for the design of effective fish passage systems. Few studies have examined burst and prolonged types of swimming performance among several co-occurring species, and swimming performance in many fish communities is undocumented. In this study, we characterize both burst (c-start velocity) and prolonged speed (critical swim speed) across a poorly documented, co-occurring group of stream fishes within the Great Basin of the western USA. We documented the variation in swim speed associated with species, habitat, and body size. Body size had an overwhelming effect on both burst speed and prolonged speed, whereas habitat use and species identity were not significant predictors. Among species, there is no evidence of a trade-off between burst swim speed and prolonged swim speed. Lack of a trade-off in performance between burst swim speed and prolonged swim speed among species may be due to unexpectedly high prolonged swim speeds exhibited by species that used substrate-bracing behaviors. Incorporating body size and variation in behavior, such as substrate-bracing behaviors, into fish passage models will likely be sufficient to ensure the passage of all species without the need to account for species-specific swimming abilities. However, these results characterize the swimming performance for threatened and common fish species such that other comparisons can be made and species-specific studies can access accurate data.
Spinristor: A Swiss Army Knife of Molecular Electronics

Here, we propose and provide in silico proof of concept of a spinristor; a new molecular electronic component that combines a spin-filter, a rectifier, and a switch, in a single molecule for in-memory processing. It builds on the idea of an open-shell transition metal ion enclosed within an elliptical fullerene connected to the source, drain, and a pair of gate electrodes. The spin- and electronic polarization due to the enclosed metal leads to differential rectification of the electrons at low voltages applied between the source-drain electrodes, VSD. The position of the encapsulated ion can be switched by a combination of a high VSD and a voltage applied between gate electrodes, VG, to switch the direction of the rectification and spin-filtering ratio. The system can thus be used as a switching rectifier and spin-filter, a spinristor. To the best of our knowledge, such a system has no macroscopic counterpart in electronics.

Genome-Wide Identification, Expression Profile, and Alternative Splicing Analysis of CAMTA Family Genes in Cucumber (Cucumis sativus L.)

The calmodulin-binding transcription activator (CAMTA), as one of the most distinctive families of transcription factors, plays an important role in plant growth and development and in the stress response. However, it is currently unknown whether CAMTA exists in cucumbers and what its function is. In this study, we first identified four CAMTA genes in the cucumber genome using a genome-wide search method. Subsequently, we analyzed their physical and chemical properties, gene structure, protein domains, and phylogenetic relationships. The results show that the structure of CsCAMTAs is similar to that of other plants, and a phylogenetic analysis divides them into three groups. The analysis of cis-acting elements shows that most CsCAMTAs contain a variety of hormones and stress-related elements. The RT-PCR analysis shows that CsCAMTAs have different expression levels in different tissues and can be induced by IAA, ABA, MeJA, NaCl, and PEG. Finally, we analyzed the expression pattern of CsCAMTAs’ alternative spliceosomes under salt and drought stress. The results show that the expression levels of the different spliceosomes are affected by the type of stress and the duration of stress. These data indicate that CsCAMTAs participate in growth and development and in the stress response in cucumbers, a finding which lays the foundation for future CsCAMTAs’ functional research.
