The connection between lateral dominance and force of handgrip was investigated by means of a repeated-measures design. 521 children participated. Performance on a paper-and-pencil task and force of handgrip were measured at the beginning of the first year at school and at the end of the first and of the second years at school. On the paper-and-pencil task 84% of the children were classified as right-handers, 8% as left-handers, and 8% as ambidexterous. About 2% of children classified as right-handers at the beginning of the first year at school were classified as left-handers at the end of the second year at school while 18% of left-handers shifted to right-handedness. 52% of children attained their best performance on handgrip with the right hand and 39% with the left hand. No differences could be found either for the right or for the left hand in force of handgrip between right- and left-handed and ambidexterous children. For right-handers, however, the more skilled hand showed superior performance in force of handgrip. These results indicate that left-handers are less strongly handed than right-handers.

The purpose of the study was to replicate findings of an earlier study of fourth grade boys manifesting mixed handedness with a sample. Among 32 mixed-handed boys in Grades 6 to 8, the right-handed writer, left-handed thrower group obtained low spelling scores (Normal Curve Equivalent Scores) on the California Achievement Test significantly more frequently than the left-handed writer, right-handed thrower group. These findings are consistent with data for Grade 4 boys in the earlier study. Findings strengthen the hypotheses that mixed handedness is not a unitary neuropsychological entity and that boys who write with the right hand and throw with the left hand might be at risk for certain academic deficits.

Descriptive Method

Human has a preference to use their hands for various manual activities. Left-handed preference is people who tend to use their left hand to perform various manual activities, while right-handed people tend to use right-handed. Any researches show that the left-handed preference for more creativity was influenced by the dominant use of the right brain and bigger corpus callosum. The research aims to determine the percentage of left-handed preference and their creativity in Universitas Papua, Manokwari Papua Barat. The method used in this research is the descriptive method. Data collection used a questionnaire to evaluate individual hand preference using Handedness Questionnaire and to determine individual creativity using Adjective Check List. The percentage of left-handed people in UNIPA were 9.3% or lower than right-handed and higher than ambidextrous. Our study supports the statement about selection in handedness in the traditional society which showed a higher percentage of left-hander as advantages related to using hand intensively.  The percentage of left-handed males and females was almost equal and strongly left-handed was higher in females. The percentage of creative people was higher in left-handed, especially in males

This paper aimed at measuring the impacts of using the process approach to teach second-year English major students at the English Department of Université de Zinder (henceforth, UZ) essay writing. Drawing on the pre-test-post-test repeated measures design, this study examined the written essays produced by the EFL students before and after the writing class. These pre and post tests were scored based on a criterial fair copy, and the scores were compared by means of an Analysis of Variance (ANOVA) to check whether there were any statistically significant differences between the mean scores. The findings revealed that the process approach had a positive impact on the participants’ essay writing skills. Also, employing Classroom Observation, the article attempted to qualitatively measure student engagement in the writing class. The findings further exuded that the EFL students observed were cognitively involved in the learning activities conducted in the class. Based on the foregoing findings, this study recommends that the process approach to (the teaching of) writing be adopted and used to teach writing in EFL classes across/in Niger.

Prior research has shown that right-handed adults perform better on a speed-tapping task with the right hand and right foot, while left-handers execute more rapidly with the left hand and right foot. Speculation is that environmental influence, most likely driving experience, may account for the right-foot bias. To examine this hypothesis further, 48 young right- and left-handed children were tested on a similar protocol. Analyses indicated no significant differences in foot performance within hand-preference groups. Since these findings do not complement reports for adults, factors such as experience or maturation might contribute to the difference. Were patterns similar, the effect of environmental influence would be assumed to be small. However, much more evidence is needed before an adequate explanation can be developed. The issue of possible environmental influence is discussed from various theoretical perspectives.

AbstractBilateral inputs should ideally improve sound localization and speech understanding in noise. However, for many bimodal listeners [i.e., individuals using a cochlear implant (CI) with a contralateral hearing aid (HA)], such bilateral benefits are at best, inconsistent. The degree to which clinically available HA and CI devices can function together to preserve interaural time and level differences (ITDs and ILDs, respectively) enough to support the localization of sound sources is a question with important ramifications for speech understanding in complex acoustic environments.To determine if bimodal listeners are sensitive to changes in spatial location in a minimum audible angle (MAA) task.Repeated-measures design.Seven adult bimodal CI users (28–62 years). All listeners reported regular use of digital HA technology in the nonimplanted ear.Seven bimodal listeners were asked to balance the loudness of prerecorded single syllable utterances. The loudness-balanced stimuli were then presented via direct audio inputs of the two devices with an ITD applied. The task of the listener was to determine the perceived difference in processing delay (the interdevice delay [IDD]) between the CI and HA devices. Finally, virtual free-field MAA performance was measured for different spatial locations both with and without inclusion of the IDD correction, which was added with the intent to perceptually synchronize the devices.During the loudness-balancing task, all listeners required increased acoustic input to the HA relative to the CI most comfortable level to achieve equal interaural loudness. During the ITD task, three listeners could perceive changes in intracranial position by distinguishing sounds coming from the left or from the right hemifield; when the CI was delayed by 0.73, 0.67, or 1.7 msec, the signal lateralized from one side to the other. When MAA localization performance was assessed, only three of the seven listeners consistently achieved above-chance performance, even when an IDD correction was included. It is not clear whether the listeners who were able to consistently complete the MAA task did so via binaural comparison or by extracting monaural loudness cues. Four listeners could not perform the MAA task, even though they could have used a monaural loudness cue strategy.These data suggest that sound localization is extremely difficult for most bimodal listeners. This difficulty does not seem to be caused by large loudness imbalances and IDDs. Sound localization is best when performed via a binaural comparison, where frequency-matched inputs convey ITD and ILD information. Although low-frequency acoustic amplification with a HA when combined with a CI may produce an overlapping region of frequency-matched inputs and thus provide an opportunity for binaural comparisons for some bimodal listeners, our study showed that this may not be beneficial or useful for spatial location discrimination tasks. The inability of our listeners to use monaural-level cues to perform the MAA task highlights the difficulty of using a HA and CI together to glean information on the direction of a sound source.

ABSTRACTProduct innovation is a strategy that must be carried out by(UMKM) in the craft business in order to always have a competitive advantage. This research is a discussion to get ceramic products that have an assessment of Indonesia so that they can compete in the global market. Parang and Kawung traditional batik motifs representing the freedom of choice of Indonesia were chosen as a form of innovation that was tried to be mixed with ceramic decorative lighting products. This batik motif is not only placed on ceramic decorative lighting products, but will be made together and become a part or character of the ceramics. This study uses a renewal method in the design of ceramic products, starting from the exploration of trends, analysis, sketching, and the last is per work design drawings or designs. Embodiment or production is done by experimentation to get the right material composition, technique, and production method or process. It will also conduct a market test by exhibiting prototype products in art-shops owned by ceramic craftsmen.The research target in the first year is the creation of techniques or production methods, and 10 ceramic designs that are in accordance with market trends and tastes. In the second year the creation of 10 prototype products and submitted to IPR, approved scientific articles, and market testing. The results of this study are expected to help craftsmen diversify their products to increase sales for the export market.ABSTRAKInovasi produk adalah strategi yang harus terus dilakukan oleh usaha mikro kecil menengah (UMKM) kerajinan agar selalu memiliki keunggulan kompetitif.

Purpose: determining peculiarities of speed characteristics of hand movements of female boxers with different functional asymmetry types during dynamic work performance. Material: 50 highly skilled female boxers (masters of sports of international class, masters of sports). The study of female boxer psychomotor functions was designed according to a certain scheme. The motor component of motor response was examined by means of tapping test. The time of a simple and two complex visual-motor responses was determined. The study was completed by determining the identification time for visual stimuli of various degrees of complexity without a motor response. It was assumed that this will allow to consider the visual-gnostic component in a "pure" form. Such a design of the study permitted to evaluate the contribution of each component of psychomotor response to the response speed of female boxers with different types of functional hemispheric asymmetry (FHA) profile. Results: For the first time, the psychophysiological indices of female boxers were obtained. Female boxers were conditionally divided into right-handers, left-handers and ambidexters. The differences of these groups of female athletes in psychophysiological indices were established. Conclusions: In convenient mode, ambidexters perform work at a high rate than right-handers. At that, their right hand is faster than the left. The total number of movements performed by left-handers is greater than that of right-handers and ambidexters (it concerns both hands). The speed characteristics of female boxers with different types of functional asymmetry in accelerated mode are the same. The pace stability of right-handers and left-handers is high, but less than that of ambidexters. Ambidexters who use the right-handed stance are at advantage than right-handers with right-handed stance. Left-handed female athletes perform movements with greater speed than right-handed ones. For right-handed and left-handed female athletes it is more difficult to maintain the optimal pace of the right than the left hand, whereas ambidexters have problems with maintaining the optimal pace of the left hand. Left-handed female athletes are faster than right-handed ones.

AbstractIn the concern for inclusiveness, one area that has been largely neglected is the discrimination against left-handedness. This paper looks briefly at some of the scriptural and social stigmas and implications attached to left-handedness. Using Luther's theology of the cross as its basis, a left-handed theology is introduced. Arguing for the need for a theology which focuses on those who are marginalized, a left-handed theology offers a model whereby God's left hand offers to those who are in “minority” positions grace and solidarity. This is contrasted to the right hand of God, which portrays a God of power, strength, and triumphalism. The hand of God which one chooses to relate to determines, then, how one does theology, and how a theological inclusiveness is developed.

Culinary business has a lot of competition which is faced by business actors. So, in the culinary business, it demands every effort to be able to compete and to defend against competitors. The increasingly fierce competition requires the entrepreneurs to think of the right strategy in competence. This becomes a business opportunity and challenge for every business that operates in Indonesia. This study aims to make the store atmosphere in culinary business able to compete and to increase the purchasing interest of the society, therefore the purpose in the first year is to conduct a field survey to record and to analyze the culinary business so that people know and are interested to visit and to buy the products that are offered. In the second year is to design and to test model, and to make brochure or pocket book about store atmosphere in culinary business. From the results of study, it shows that the store atmosphere in culinary business in Sub-District of Percut Sei Tuan if it is viewed from the store exterior indicator, it has less good value with an average value of 3.216, general interior also has less good average value with an average value of 2.984, while store layout in the business has good value with an average value of 3.578 means that business owners can maintain by improving existing facilities, store displays have less good average value with an average value of 3.328. If it is seen from the results, it is expected that culinary business owners in the Sub-District of Percut Sei Tuan should improve the atmosphere of business place for purchasing interest of society to emerge. Besides store atmosphere indicator, the addition of other indicators is the purchasing interest of the society in which the average value that is generated from the questionnaire is still showing less good value with an average value of 3.3, it means that it becomes a problem for culinary business in Sub-District of Percut Sei Tuan.

Stability analysis of wheat genotypes under rainfed timely sown trials in Northern Hills Zone of India by Additive main & multiplicative interactions (AMMI) analysis observed highly significant effects of the environment, GxE interaction and genotypes during 2018-19 and 2019-20. The ranking of genotypes had altered with utilization of more number of IPCA’s in AMMI and WAASB measures. Environments contributed about 53%, GxE interaction accounted for 30.5% and Genotypes explained only 5.4% of the total sum of squares due to treatments in the first year. Wheat genotypes HS668,  VL2035, VL2036 , HS562 had been selected by Analytic measures of adaptability and Superiority indexes. Different quadrants comprised of a cluster of arithmetic, geometric, harmonic means along with corresponding adaptability measures. Superiority Indexes considering averages grouped separately. This group maintained the right angles with a group of MASV & MASV1 measures. Clustering of Adaptability measures as per arithmetic, geometric and harmonic means placed in a quadrant. Second-year reflected VL2041,  HS675, HS676 & HS562, HPW471 genotypes selected by adaptability and superiority indexes. About 68% of the total variation with 38.4% and 30.2% contributions by PC1 & PC2. Adaptability measures maintained the right angle with other stability measures, with the exception of  Superiority indexes.  There is an additional advantage with these measures to assign variable weights to the yield and stability as per the goal of breeding trials. These indexes have the potential to provide reliable estimates of genotypes in future studies as they are considered more number of significant IPCA’s in biplots.
