Abstract
Chen, CH, Chang, CK, Tseng, WC, Chiu, CH, Dai, X, and Ye, X. Acute effects of different warm-up protocols on sports performance in elite male collegiate handball players. J Strength Cond Res 36(8): 2262–2267, 2022—This study aimed to examine the effects of 3 different warm-up protocols on subsequent sports performance in elite male collegiate handball players. Fifteen handball players (19.0 ± 2.4 years) completed 3 separated randomly sequenced experimental visits. During each visit, they started with different warm-up protocols (traditional warm-up [TRAD] vs. warm-up with core stability exercises [CORE] vs. warm-up with elastic band exercises [ELAS]) and completed with a series of randomly ordered sport-specific performance testing measurements: 30-m sprint, countermovement jump, medicine ball overhead forward throw, and standing and jump handball throw tests. Both CORE and ELAS protocols induced statistically significant differences (p < 0.05) on overall sports performance (sprint time, jump height, medicine ball throwing peak velocity and power, and handball throwing velocities), as compared to the TRAD. In addition, the ELAS protocol imposed small-to-medium effects (effect size range: 0.45–0.82), enhancing handball throwing velocity and medicine ball throwing performance comparing with the CORE. Sport-specific warm-up protocols that contain core stability or elastic band–based exercises likely induced subsequent performance enhancements (sprint, jump, and throw) in elite male collegiate handball players when compared with TRAD. Furthermore, including elastic band exercises in the warm-up protocol even induced superior upper-body performance enhancement (explosive power and handball throwing velocity) than other protocols. Therefore, preconditioning warm-up activities using elastic band–based exercises can be integrated into a traditional sport-specific warm-up protocol for elite collegiate handball players before competition or training.

ABSTRACT
This study assessed the effectiveness of multi-ingredient preworkout supplements (MIPSs) when compared with placebo on strength, power, exercise volume, and anaerobic capacity in healthy resistance-trained individuals. Twenty-two (n = 22) studies and 458 participants were included. Quality of outcomes was rated as low and was downgraded mostly because of imprecision and high risk of bias. Optimal forms and strategies on MIPS consumption and use has not yet been rigorously examined. Although improvements were noted for lower body strength (repetitions) and upper body power (Watts), most results were inconclusive, and the results showing improvements were presented in low-quality studies (see Video Supplemental Digital Content 1, http://links.lww.com/SCJ/A276).
Effects of Efferent Activity on Hair Bundle Mechanics
Authors: Lin Chia-Hsi Jessica , Bozovic Dolores 
Published: February 2020

Hair cells in both the auditory and vestibular systems receive efferent innervation. A number of prior studies have indicated that efferent regulation serves to diminish the overall sensitivity of the auditory system. The efferent pathway is believed to affect the sensitivity and frequency selectivity of the hair cell by modulating its membrane potential. However, its effect on the mechanical response of the hair cell has not been established. We explored how stimulation of the efferent neurons affects the mechanical responsiveness of an individual hair bundle. We tested this effect onin vitropreparations of hair cells in the sacculi of American bullfrogs of both genders. Efferent stimulation routinely resulted in an immediate increase of the frequency of hair bundle spontaneous oscillations for the duration of the stimulus. Enlarging the stimulus amplitude and pulse length, or conversely, decreasing the interpulse interval led to oscillation suppression. Additionally, we tested the effects of efference on the hair bundle response to mechanical stimulation. The receptive field maps of hair cells undergoing efferent actuation demonstrated an overall desensitization with respect to those of unstimulated cells.SIGNIFICANCE STATEMENTThe efferent system is an important aide for the performance of the auditory system. It has been seen to contribute to sound detection and localization, ototoxicity prevention, and speech comprehension. Although measurements have demonstrated that efference suppresses basilar membrane movement, there is still much unknown about how efferent activity affects hearing mechanics. Here, we explore the mechanical basis for the efferent system's capabilities at the level of the hair bundle. We present optical recordings, receptive field maps, and sensitivity curves that show a hair bundle is desensitized by efferent stimulation. This supports the hypothesis that efferent regulation may be a biological control parameter for tuning the hair bundle's mechanical sensitivity.

BACKGROUND AND OBJECTIVES:
The Vaccines for Children Program (VFC) provides vaccines for children who may not otherwise be vaccinated because of financial barriers. Pediatrician participation is crucial to the VFC’s ongoing success. Our objectives were to assess, among a national sample of pediatricians, (1) VFC program participation, (2) perceived burden versus benefit of participation, and (3) knowledge and perception of a time-limited increased payment for VFC vaccine administration under the Patient Protection and Affordable Care Act.

METHODS:
An electronic and mail survey was conducted from June 2017 to September 2017.

RESULTS:
Response rate was 79% (372 of 471); 86% of pediatricians reported currently participating in the VFC; among those, 85% reported never having considered stopping, 10% considered it but not seriously, and 5% seriously considered it. Among those who had considered no longer participating (n = 47), the most commonly reported reasons included difficulty meeting VFC record-keeping requirements (74%), concern about action by the VFC for noncompliance (61%), and unpredictable VFC vaccine supplies (59%). Participating pediatricians rated, on a scale from −5 (high burden) to +5 (high benefit), their overall perception of the VFC: 63% reported +4 or +5, 23% reported +1 to +3, 5% reported 0, and 9% reported −1 to −5. Of pediatricians, 39% reported awareness of temporary increased payment for VFC vaccine administration. Among those, 10% reported that their practice increased the proportion of Medicaid and/or VFC-eligible patients served on the basis of this change.

CONCLUSIONS:
For most pediatricians, perceived benefits of VFC participation far outweigh perceived burdens. To ensure the program’s ongoing success, it will be important to monitor factors influencing provider participation.
MODELING OF BIOMECHANICAL SYSTEM ELEMENT STRUCTURE
Authors: Pogrebnoy O. V. 
Published: February 2020

The element structure of a biomechanical system subjected an action of external force factors is studied. The radiocarpal joint of wrist is regarded as biomechanical system. The scaphoid bone is one element of the biomechanical system under investigation. The morphometrical analysis of cuts made in scaphoid frontal plane is fulfilled. The increase of bone tissue density from the cut centre to its periphery is revealed. The significant difference of bone tissue density in proximal and distal parts is determined too. The revealed tendencies allow us to develop the recommendations of construction design for scaphoid osteosynthesis.

Published: February 2020

A proposed the model of a radioline “space-to-Earth” with more informative for a low orbit university nanosatellite. The radioline is modeled on a antenna of the high-frequency S-band. At present time, the tasks of creating radiolines “space-to-Earth” in the conditions of limited energy of satellites with more informativeness (for telemetry radiolines and information radiolines) constantly require increasing their capabilities. Various options are being developed to implement such a solution, ranging from increasing the data transmission time due to repeaters and developing new encoding methods and increasing the bandwidth of radio lines. One solution is to use middle or high gain antennas.
The model of a radioline is designed on the basis of the high-frequency (S-band) antenna. The calculations were carried out according to the international format of the AMSAT-IARU-Link-Model program. The calculation of the proposed the model consists of three basic conditions: the greatest loss of energy of the radio signal in free space, equivalent to isotropic radiating power and quality factor of the receiving station. The proposed model is built on the basis of a phased antenna array with a gain of 12 dBi for transmit from nanosatellite, the gain of the receiving antenna is 35 dBi. The results showed the ability to transmit up to 50 images of the Earth's surface per day. The use of a phased array antenna and the transition to the S-band allowed with smaller dimensions to increase the antenna gain and the rate of information transmission in communication sessions.
Geoarchaeological evaluation of the Roman topography and accessibility by sea of ancient Osor (Cres Island, Croatia)
Authors: Draganits Erich , Gier Susanne , Doneus Nives , Doneus Michael 
Published: February 2020

Abstract
We combine geoarchaeological investigations with high-resolution airborne laser scanning (ALS) topographic and airborne laser bathymetric (ALB) measurements to reassess the topography of the Roman city of Apsorus (modern Osor, northeastern Adriatic Sea, Croatia), which has generally been interpreted as important nodal point of Roman maritime traffic. Apsorus is located at the isthmus connecting Cres and Lošinj islands, which is 90 m wide at the narrowest part and dissected by a canal of supposed Roman age. A conspicuous low-lying wetland north of the city has been suggested to be a former sea passage and harbour area. Geoarchaeological coring, sedimentological analysis and radiocarbon dating suggest that this depression was already silted up with terrestrial sediments some 6,000 years ago and, especially in combination with the lower sea-level at that time, could not have been a Roman harbour. The combination of the ALS/ALB topographic data with lower sea-levels reconstructed for the Roman period challenges the traditional view which places ancient Osor on a small island and allows for new interpretations of the accessibility of Osor by sea.
Is hydrotectonics influencing the thermal spring in Eisensteinhöhle (Bad Fischau, Lower Austria)?

Abstract
Eisensteinhöhle is a 2 km long crevice cave that is significantly overprinted by hydrothermal karst processes. It was opened during quarrying in the Fischauer Vorberge, at the western margin of the Vienna Basin. This pull-apart basin cuts the eastern foothills of the Alps and is formed by a major NE-SW striking, sinistral transform fault. The western margin consists of NNE-SSW striking normal faults creating paths for thermal water to rise from the central basin. The deepest part of the cave, 73 m below the entrance, hosts a pond with 14.6 ±0.2 °C warm water that occasionally acts as a spring. The water level and temperature fluctuate and at a certain level, water visibly discharges into a nearby narrow fissure. As sporadic observations of the water level since 1992 gave no obvious connection to precipitation events, the connection to an aquifer and the origin of the water remained unknown. A pumping test, conducted on 13/7/2016, yielded a volume of the spring/pool of about 2.8 m3 that is fed by a very small inlet at the sandy bottom. At the time of the pumping test, the discharge was only 4.5 l/h but during previous overflow events, discharge values of up to 289 l/h were recorded.
Water temperature and hydrochemistry hint towards a mixture of an old thermal component and a young meteoric component. During continuous monitoring of water level and temperature from October 2015 until November 2018, the water level was almost stable with few periods of high level (almost at overflow) that lasted for about 3 to 4 weeks each. The water temperature increased during most high stands and is positively correlated with the water level. Correlation of the high-resolution data on water level and temperature fluctuations with precipitation measurements at the nearest meteorological stations show a relation of water level to certain rainfall events and the sporadically taken long time records show a correlation with annual precipitation sums. Long-term observations also indicate a connection to groundwater levels in the Vienna Basin with a delay of about 8 weeks in Bad Fischau. In July 2017, the water level dropped suddenly and then recovered simultaneously in the time of several weak earthquakes in the vicinity. The data suggest that the spring in Eisensteinhöhle is influenced by precipitation. For one seismic event, there is a correlation with unusual water level changes at Eisensteinhöhle, but the rareness of earthquakes demands for a longer time series to confirm this observation.
The Alland earthquake sequence in Eastern Austria: Shedding light on tectonic stress geometry in a key area of seismic hazard

Published: February 2020

Abstract
We present our results on the fault geometry of the Alland earthquake sequence in eastern Austria (Eastern Alps) and discuss its implications for the regional stress regime and active tectonics. The series contains 71 known events with local magnitudes 0.1 ≤ M

L
≤ 4.2 that occurred in between 2016 and 2017. We locate the earthquakes in a regional 3D velocity model to find absolute locations. These locations are then refined by relocating all events relative to each other using a double-difference approach, based on relative travel times measured from waveform cross-correlation and catalogue data. We also invert for the moment tensor of the M

L
= 4.2 mainshock by fitting synthetic waveforms to the recorded seismo-grams using a combination of the L1- and L2-norms of the waveform differences. Direct comparison of waveforms of the largest events in the sequence suggests that all of them ruptured with very similar mechanisms. We find that the sequence ruptured a reverse fault, that is dipping with ~30° towards ~north-northeast (NNE) at 6–7 km depth. This is supported by both the hypocentres and the mainshock source mechanism. The fault is most likely located in the buried basement of the Bohemian massif, the “Bohemian Spur”. This (reverse) fault has a nearly perpendicular orientation to the normal-fault structures of the Vienna Basin Transfer Fault System further east at a shallower depth, indicating a lateral stress decoupling that can also act as a vertical stress decoupling in some places. In the west, earthquakes (at a larger depth within the upper crust) show compressive stresses, whereas the Vienna Basin to the east shows extensional (normal-faulting) stress. This provides insight into the regional stress field and its spatial variation, and it helps to better understand earthquakes in the area, including the “1590 Ried am Riederberg” earthquake.
Ukraina w polityce zagranicznej Polski w dobie drugiego rządu zjednoczonej prawicy pod egidą Prawa i Sprawiedliwości (2015-2018)
Authors: Mróz Maciej 
Published: February 2020

Dotychczasowy model relacji polsko-ukraińskich dobiega końca, a nowy znajduje się w fazie in statu nascendi. Zasadnicza sprzeczność podstawowych interesów Kijowa i Warszawy spro-wadza się do tego, że podczas gdy Ukraina szuka sposobów na integrację i potrzebuje silnej Europy oraz ipso facto wzmocnienia wspólnoty europejskiej, Polska pod rządami koalicji skupionej wokół PiS kroczy coraz śmielej w stronę eurosceptycyzmu i podważania spójności Unii Europejskiej, chociaż wahadło europejskiej polityki po wyborach w Austrii, Holandii, a zwłaszcza we Francji w 2017 r. ponownie wychyla się w stronę centrum. Dzisiejsza Polska, odwracając się plecami od europejskiego twardego jądra, a zatem od Niemiec i Francji, przestaje być także atrakcyjnym partnerem dla Ukrainy, która z kolei widząc słabnącą pozycję Polski, zacieśnia związki z Berlinem.
Relations between self-esteem dimensions and fundamental social motives
Authors: Kozłowska Monika A. 
Published: February 2020

The article presents the concept of fundamental social motives, which is novel for Polish readers, and its relations with self-esteem. The studies conducted so far suggest that there may be significant correlations between various dimensions of self-esteem and fundamental motives focused on interpersonal relations (affiliation motives and mate acquisition/retention motives). Data was collected from a sample of N = 363 subjects in order to find predictors for the level and stability of self-esteem. The results include correlations between 11 scales measuring fundamental motives and self-esteem dimensions: its level and instability. Multiple regression analyses with self-esteem measures as explained variables and motives related to sociometer theory as explanatory variables were also conducted. The article presents a detailed discussion of regression analysis results for male and female samples. Limitations and future research directions are also discussed.

Performance, Interaction, and Satisfaction of Graduate EAP Students in a Face-to-Face and an Online Class: A Comparative Analysis
Authors: Stanchevici Dmitri , Siczek Megan 
Published: February 2020

Before arriving in a host country, international students may be motivated to complete some institutional requirements online. Many studies address computer-assisted instruction for second-language students, but few focus on fully online English for Academic Purposes (EAP) writing courses. This comparative case study, grounded in action research, examined the extent to which a fully online version of a graduate-level EAP course offered to international students at a North American university achieved comparable outcomes to a face-to-face version. A quantitative and qualitative analysis of study participants’ performance and course evaluations indicated that the outcomes and student satisfaction of both cohorts were comparable. However, an examination of the participants’ final research papers and online interactions revealed differences and challenges. Based on these findings, it is recommended that future online courses provide more instruction on source integration, library research, and building an interactive learning community. Overall, the findings suggest that when carefully designed, assessed, and refined, fully online courses hold strong promise in EAP academic writing contexts.
Les étudiantes et étudiants internationaux tiennent parfois à remplir certaines exigences institutionnelles en ligne avant de se rendre dans leur pays d’accueil. L’enseignement assisté par ordinateur pour les apprenantes et apprenants d’anglais langue seconde fait l’objet de nombreuses études, mais peu d’entre elles portent sur des cours d’écriture d’anglais académique (EAP) complètement dispensés en ligne. Entièrement basée sur la recherche-action, la présente étude de cas comparative fait état du degré de comparabilité des résultats d’un cours d’anglais académique de deuxième cycle complètement présenté en ligne à des étudiantes et étudiants internationaux inscrits à une université nord-américaine et des résultats obtenus lorsque le même cours était dispensé en personne. Une analyse quantitative et qualitative des rendements des participantes et participants et du cours lui-même a indiqué que les résultats et le degré de satisfaction des étudiantes et étudiants des deux cohortes se valaient. L’examen des rapports de recherche finaux des participantes et participants et celui des interactions en ligne ont toutefois révélé des écarts et des défis. Sur la base de ces constatations, il est recommandé que les futurs cours en ligne fournissent davantage d’instructions sur l’intégration des sources, sur les recherches en bibliothèque et sur la construction d’une communauté d’apprentissage interactif. Dans l’ensemble, les constatations de l’étude suggèrent que, s’ils sont soigneusement conçus, évalués et peaufinés, les cours complètement dispensés en ligne sont très prometteurs dans des contextes d’écriture en anglais académique.
