MYOELECTRIC COMPARISON OF TABLE TENNIS FOREHAND STROKE USING DIFFERENT BALL SIZES

The aim of this study was to examine the differences between forehand top spin strokes with 38 mm and 40 mm balls in table tennis. The participant was filmed as he executed the strokes. To ensure the same condition for all the performances (the same approaching ball trajectory), a table tennis machine was used. Electrodes were placed on the right side of the player’s body due to his right5handedness. Absolute muscle involvement was estimated on the basis of averaged EMG signals (mV) measured in all muscles (m. biceps brachii, m. deltoideus, m. pectoralis major). Analysis of variance (ANOVA) was used for calculating differences between overall mean values of averaged EMG signals among all muscles. The peak EMG amplitude of the m. deltoideus anterior reached a value of 2.5 mV, for the 38 mm ball stroke. The comparable contraction values in strokes with balls of both sizes were obtained with the m. deltoideus medialis: the peak values ranged between 2.3 and 2.8 mV with a 38 mm ball and between 2.2 and 3.0 mV with a 40 mm ball. For the m. biceps brachii the peak EMG amplitude ranged from 1 to 2.2 mV and from 1.3 to 2.4 mV for the 38 mm and 40 mm ball strokes, respectively. A similar result was obtained for the m. pectoralis major contractions. Rather uneven intensities of contractions were obtained for the 38 mm ball strokes, ranging from 1.5 mV to 2.6 mV. More balanced values were obtained for the 40 mm ball strokes ranging from 1.6 to 2.2 mV. These findings showed us that in three observed muscles (m. deltoideus anterior, m. biceps brachii, m. pectoralis major) differences in the intensity of EMG signals are significant, so we can conclude that the player uses more muscle activities in a stroke with the larger ball, and also we conclude that the contraction of m. pectoralis major is more powerful when the player hits the larger ball.
IT support in manufacturing firms for a knowledge management dynamic capability link to performance

Information technology (IT) is applied in many settings of knowledge management (KM) under the premise that a manufacturing organization will gain direct benefit from the investment. However, direct links from investment in IT to organizational performance have always been elusive. Strategic management research presents a concept of dynamic capabilities to model the ability of an organization to respond effectively to changes in the environment and leverage performance. By using this capability as a mediating variable, IT support of KM is shown to indirectly benefit manufacturing organizations in a sample of managers from 500 manufacturing firms in Taiwan. This link indicates firms must carefully align the IT support to strategic needs.
Sitio Laguna Las Vegas: procesamiento y consumo de guanacos (Lama guanicoe) en la cuenca media del río Coyle (provincia de Santa Cruz)

El sitio Laguna Las Vegas posee una alta integridad y resolución. Es un registro penecontemporáneo formado alrededor de 3050-3210 años AP que se destaca por la alta frecuencia de restos de guanaco (Lama guanicoe) y, en menor magnitud, de cauquén (Chloephaga sp.), acompañados principalmente por machacadores óseos y raspadores de calcedonia. Se postula que el sitio es el resultado del descarte en un campamento formado atricionalmente y en un corto lapso, al que habrían ingresado presas enteras (guanacos) para su procesamiento, consumo y ulterior transporte del esqueleto axial. La presencia de restos de cauquén indica que las ocupaciones humanas habrían tenido lugar, al menos, durante los meses de primavera y verano. Todas estas características lo definen como un sitio novedoso que añade valiosa información sobre el manejo de recursos faunísticos y la movilidad de poblaciones cazadoras-recolectoras en la cuenca media del río Coyle.
Ultrasonic Guided Wave Imaging Techniques in Structural Health Monitoring

Ultrasonic guided waves, due to their capability of interrogating a large structure from a single sensor position, have been proven as a promising tool for structural health monitoring. In this article, we present two imaging approaches of utilizing guided wave leave-in-place sensors for early detection of defects in plate-like structures. The first approach is based on a guided wave tomographic technique, in which the region surrounded by a sparse sensor array is monitored. The second one is a phased array approach, in which sensors are attached to a structure in a compact format to form an array. The region subjected to inspection and monitoring is the region outside the array. Both techniques have shown excellent capability of determining damage size, location, and severity.
Earthquake and Ambient Vibration Monitoring of the Steel-Frame UCLA Factor Building

Dynamic property measurements of the moment-resisting steel-frame University of California, Los Angeles, Factor building are being made to assess how forces are distributed over the building. Fourier amplitude spectra have been calculated from several intervals of ambient vibrations, a 24-hour period of strong winds, and from the 28 March 2003 Encino, California ( ML =2.9), the 3 September 2002 Yorba Linda, California ( ML =4.7), and the 3 November 2002 Central Alaska ( Mw =7.9) earthquakes. Measurements made from the ambient vibration records show that the first-mode frequency of horizontal vibration is between 0.55 and 0.6 Hz. The second horizontal mode has a frequency between 1.6 and 1.9 Hz. In contrast, the first-mode frequencies measured from earthquake data are about 0.05 to 0.1 Hz lower than those corresponding to ambient vibration recordings indicating softening of the soil-structure system as amplitudes become larger. The frequencies revert to pre-earthquake levels within five minutes of the Yorba Linda earthquake. Shaking due to strong winds that occurred during the Encino earthquake dominates the frequency decrease, which correlates in time with the duration of the strong winds. The first shear wave recorded from the Encino and Yorba Linda earthquakes takes about 0.4 sec to travel up the 17-story building.
Residual energy-based clustering in UAV-aided wireless sensor networks for surveillance and monitoring applications

Aim: Unmanned aerial vehicle (UAV)-aided wireless sensor networks (WSNs) are effectively used for surveillance, monitoring, and rescue applications in military and commercial domains. In UAV-aided WSNs (UWSNs), efficient data gathered from sensor nodes are desired to enhance network performance. However, communication between UAV and sensor nodes is challenging due to the high mobility of the UAV and a large number of sensor nodes. Clustering in UWSNs limits the number of sensor nodes communicating with the UAV, i.e., only the cluster head in a cluster can transmit the sensed data to the UAV, which reduces collision probability. Methods: In this paper, we propose a residual energy-based clustering algorithm for sensor-to-UAV communication in UWSNs. The cluster size and the number of sensor nodes in a cluster are determined on the basis of the residual energy of the sensor nodes. The performance of the proposed algorithm is evaluated by using the MATLAB simulator and then compared with that of the conventional clustering algorithm. Results: According to our extensive simulation results, the proposed clustering scheme significantly outperforms the conventional one in terms of network lifetime and data delivery ratio. Conclusion: Hence, through our studies and simulations, it can be assured that the network lifetime of UWSNs can be prolonged and the throughput of the network can also be elevated by controlling the early death of sensor nodes due to the uneven energy consumptions. We will come up with further analysis and validation of our work in the future.
Aging population and agricultural sustainability issues: case of turkey

Agriculture is a sector that is widely known to be impacted not only by the natural conditions of a country but also by other economic and political sectors. Turkish agriculture, in a context marked in recent years by a rural exodus of young people, marks the vagueness of the current state of the agricultural sector and its future. It is with this in mind that this research was carried out, based on a questionnaire survey of 312 producers in 5 provinces of Turkey, to assess the impact of the ageing of the rural population on the agricultural sector. The results of this study show that with age, producers invest less in agricultural activity, altogether abandoning productions requiring more labour. The possibility of taking over the family farm by descendants plays an important role in the degree of involvement of producers. Through these findings, this study makes it possible to address targeted agricultural policies according to age stages.

Robust active vibration control of piezoelectric flexible structures using deterministic and probabilistic analysis

The main objective of this article is to propose a general and systematic robust control methodology for active vibration control of piezoelectric flexible structures such that the probabilistic information of parametric uncertainties can be investigated, and the robustness properties of the closed-loop system can be quantitatively ensured. For the purpose, the modal parameter identification is performed based on the finite element analysis to have the reduced nominal dynamical models. The generalized polynomial chaos framework is employed for uncertainty analysis to obtain the probabilistic information of parametric uncertainties. In the presence of probabilistic parametric and dynamic uncertainties, phase and gain control policies–based H ∞ output feedback control is used for the controller design to ensure a set of control objectives simultaneously, and then deterministic and probabilistic robustness analyses are conducted to quantitatively verify the robustness properties of the closed-loop system both in the deterministic sense and in the probabilistic one. The design process and the effectiveness of the proposed control methodology are illustrated via active vibration control of a piezoelectric cantilever beam.
Experience of Diabetes Perceived through Daily Living That Was Totally Changed by An Unexpected Disaster—From The Narrative of A Person Who Did Not Record The Indexes

Purpose: To phenomenologically describe the experience of living with diabetes based on the narrative of a person who did not record diabetic indexes. Methods: A phenomenological approach was employed, which describes the world as it appeared to the person. This article is based on the narrative obtained from an unstructured interview of a participant the author met during a diabetic logbook development project and found that she was not keeping a record of her diabetic indexes. Results: After experiencing a huge earthquake Ms A, due to her various concerns for her loved ones and business, spent more time worrying about them without really paying attention to her own illness of diabetes. As her condition worsened, she was required to get a regular injection which she decided not to do herself but to get from a doctor. This made her become kinder to herself. This change of attitude was derived from the way she perceived her time and the way she cared for herself. Conclusion: The experience of the rejuvenating time generated from the rhythm of caring for herself by regularly seeing the doctor was also representative of her recovery from the disaster. Ms. A, who chose to care for herself by relying on the doctor and valuing the conversations with him, may not have needed to self-monitor the indexes. Her case suggests a new way of self-caring that does not necessarily require self-monitoring.
Total valve management—The key to better process plant operations

Looks at a system for diagnosing valve performance which works by measuring or inferring dynamic parameters such as valve travel, friction, seat load, seat contact and supply pressure by using sensors attached to the valve instrumentation. The system, which can be used in a factory or to taken to a valve on site, interprets the results and stores the test data. Gives application examples in the fertiliser and paper industries and continues that the next step will to embed diagnostics within the valve instrumentation itself. Concludes that the concept of “total valve management” in reducing costs helping plants operate more effectively will become increasingly important to manufacturers in coming years.

FUNCIONAMIENTO DE EMPRESAS DE BASE TECNOLÓGICA: OBTENCIÓN DE RECURSOS ESTRATÉGICOS EN LAS JUNTURAS CRÍTICAS

This study analyzes alliance between Technology Based Firms (TBF) as a strategy to obtain strategic resources. Taking as reference the model from Vohora et al (2004), who determined that the TBFs perform better when they rely on strategic alliances at critical transitions in their stages of performance and development. Strategic alliances or strategic interactions assist these firms in gaining access to valuable resources. Through the alliances, cost and risk of developing strategic resources can be reduced. However, strategic alliances have the risk of competitive imitation since it exposes the base of strategic resources in which the competitive advantage is sustained. In this sense, from the theoretical perspective, competitive advantage (Resources Based View) and technology based firms, sharing strategic resources could be considered an anomaly. The present study analyzes this anomaly. JEL: M13; M21
Critical Issues in Risk Homeostasis Theory

Instead of a response, this rejoinder should perhaps be called "an attempt at a response. " The many critical issuesraised by as many as six authors from varied disciplinary backgrounds undoubtedly deserve more profound and detailed study than was possible for an expeditious and reasonably succinct reply. The present discussion, therefore, focuses upon those issues that appear to be among the most crucial: the question of empirical verified ability; testing the theory on new data; the strength of counter evidence; the relation to conventional utility theory; questions of modeling and aggregation; and the nature of homeostasis and how it is maintained. Several new empirical observations are brought into the debate. Language: en

A mixed methods case study on the use and impact of web-based lexicographic tools on L2 writing

Abstract This study used a mixed methods research design to investigate use of Web-based lexicographic tools during real-time second language (L2) writing activity in an English as a foreign language university context and the impact of their use on writing quality. Participants included 22 adult Japanese EFL learners, elementary to advanced language proficiency, and their tutor. Data were collected using digital screen capture and eye-tracking technologies while participants wrote a 35-minute essay. Supplementary stimulated retrospective recalls were also conducted to document participants’ reflections on the use of these tools during the full writing event. Results revealed that participants spent, on average, 15% of composing time consulting online tools, with bilingual resources the most used. Importantly, mediation analysis found that L2 proficiency was the main, and direct, predictor of essay score. These findings as well as specific patterns of use discerned are discussed with reference to the qualitative data before proposals for further research and pedagogical implications are considered. Supplemental data for this article is available online at https://doi.org/10.1080/09588221.2021. 1987273 .
Poultry Consumption and Human Health: How Much Is Really Known? A Systematically Searched Scoping Review and Research Perspective

The purpose of this scoping review was to systematically search and chronicle the available scientific literature pertinent to chicken/poultry intake and human health. The protocol was uploaded to Open Science Framework (https://osf.io/2k7bj/) and was conducted in accordance with recommended guidelines from PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) extension for scoping reviews (PRIMSA-Scr). Articles and scientific literature of all types (observational, experimental, narrative/literature reviews, systematic reviews and meta-analyses) assessing chicken/poultry intake and human health were included. A total of 13,141 articles were identified and 540 met the inclusion criteria. Among these 540 articles, 212 articles focused on cancer morbidity and mortality; 22 on cancer risk factors; 41 on cardiovascular disease (CVD) morbidity and mortality; 52 on CVD risk factors; 32 on diabetes morbidity and mortality; 33 on diabetes risk factors; 42 articles on body weight and body composition, and 181 categorized as “Other”, which included nutrient status, psychological well-being/mental health, cognitive outcomes, microbiome outcomes, chronic kidney disease, non-alcoholic fatty liver disease, skin disorders, and fertility, among others. Among the included articles, 373 were observational, 77 were reviews and meta-analyses and 70 were experimental. This scoping review systematically identifies scientific literature pertinent to poultry intake and all facets of human health. It provides the types of article designs that exist for each designated health outcome, as well as the years in which research was published by health outcome. This review highlights areas where poultry research is apparently lacking. The influences of processed poultry in human health outcomes should be assessed, and cooking methods of poultry should be reported in both RCTs and OBS articles to understand the role of poultry more completely in human health outcomes. This review also provides suggestions for potential RCTs that would help to elucidate the effects of consuming fresh versus processed poultry products on cardiometabolic and cancer risk factor outcomes. Additionally, this review gave guidance on where systematic reviews assessing poultry intake and the following health outcomes are warranted: body mass index/overweight/obesity, CVD morbidity and mortality, and T2DM risk factors and morbidity.
NETWORK LIMITS ON RESIDENTIAL HEAT PUMP CAPACITY AS AN ENABLING TECHNOLOGY TOWARDS RENEWABLES INTEGRATION

In addition to increasing the share of renewables in power systems, there is also growing interest in the electrification of the heating sector; in particular, via the installation of residential heat pumps. This new load category will increase the demand from domestic customers and reduce the natural diversification of loads in low voltage (LV) networks, with implications, at certain times, for the loading levels of network assets, and voltage drops at the extremes of the LV feeders. This paper assesses the volume restrictions that LV feeders are likely to require on the widespread installation of heat pumps for different domestic settings. Consequently, a set of real LV feeders, for selected scenarios, is investigated for different levels of heat pump penetration, network loading conditions and upstream voltage levels. The hosting capacity of the feeders under study is determined and mapped against feeder topological features. Moreover, correlation analysis between the duration and severity of voltage and congestion problems, for different feeder characteristics is performed.
Identifying Critical Issues in the Horticulture Industry: A Delphi Analysis during the COVID-19 Pandemic

The horticulture industry provides significant contributions to society, including healthy foods, economic development, recreation and leisure activities, among others. However, there are critical issues facing the horticulture industry which should be illuminated to ensure ongoing vitality and relevance, particularly within the COVID-19 pandemic context. The present study used the Delphi Technique to identify the most critical issues facing the horticulture industry as perceived by a panel of industry experts. Data were collected from February to October 2020 and thus preceded the initial declaration of COVID-19 as a global pandemic through the lifting of stay-at-home orders in most states. The expert panel arrived at a consensus on 34 specific issues, five of which were specifically related to the COVID-19 pandemic. Using the Constant Comparative Method, the issues were thematically analyzed and grouped into five primary categories, including (alphabetically ordered): (1) disease and pest management, (2) education, research, and recruitment, (3) environmental conditions and natural resource availability, (4) labor challenges and considerations, and (5) production challenges and innovations. The results of the study provide a framework for both academic and practitioner audiences to identify critical focus areas for the industry within a COVID-19 context.
