Authors: Jansen Marleen G. T. , Huijgen Barbara C. H. , Faber Irene R. , Elferink-Gemser Marije T. 
Published: May 2021

ABSTRACT
A systematic review in PubMed, Web of Science, SPORTDiscus, PsycINFO, and Google Scholar was conducted to provide a state-of-the-science overview of agility tests in the racquet sports tennis, badminton, and squash while evaluating their measurement properties. Twenty articles were included covering 28 agility tests. Results showed 10 sport-specific agility tests of which 5 were assessed on reliability and 6 on validity. Both the Badcamp and the badminton-specific speed (“agility”) test were identified as suitable agility tests available for badminton. For tennis and squash, there were no sport-specific agility tests identified in the literature showing both reliable and valid results. Future research should focus on developing sport-specific agility tests for tennis and squash, including assessment of the reliability and validity of the tests.
Prevalence and predictor for malignancy of contralateral thyroid nodules in patients with unilateral PTMC: a systematic review and meta-analysis
Authors: Wang Weidi , Kong Lingjun , Guo Hongkun , Chen Xiangjin 
Published: May 2021

Abstract

Background
The presence of clinically negative nodules on the contralateral lobe is common in patients with unilateral papillary thyroid microcarcinoma (PTMC). The appropriate operational strategies of contralateral thyroid nodules remain controversial. In this study, we analyzed clinical features that could be predictors for malignancy of contralateral thyroid nodules coexisting with diagnosed unilateral PTMC.

Methods
The literatures published from January 2000 to December 2019 were searched in PubMed, Cochrane Library, Embase, Web of Science, CNKI, and Wan Fang database. Odds ratio (OR) with 95% CI was used to describe categorical variables. Heterogeneity among studies was examined by the Q test and I2 test; potential publication bias was detected by Harbord test and ‘trim and fill’ method.

Results
In this meta-analysis, 2541 studies were searched and 8 studies were finally included. The results showed that the rate of carcinoma in contralateral nodules was 23% (OR = 0.23, 95% CI = 0.18–0.29). The pooled data indicated that contralateral malignancy was not associated with age, gender, primary lesion size, ipsilateral central lymph node metastasis and multifocality of contralateral lesion. The following variables have correlations with an increased risk of contralateral malignancy: multifocality of primary carcinomas (OR = 3.93, 95% CI = 2.70–5.73, P < 0.0001), capsular invasion (OR = 1.61, 95% CI = 1.10–2.36, P = 0.01), and Hashimoto's thyroiditis (OR = 1.57, 95% CI = 1.13–2.20, P = 0.008).

Conclusions
Based on our meta-analysis, the rate at which contralateral malignancies are preoperatively misdiagnosed as benign is 23%. The risk factors for contralateral malignancy in unilateral PTMC patients with contralateral clinical negative nodules include multifocality of primary carcinomas, capsular invasion, and Hashimoto's thyroiditis.

AbstractObjectiveSocial media disorder (SMD) is an increasing problem, especially in adolescents. The lack of a consensual classification for SMD hinders the further development of the research field. The six components of Griffiths’ biopsychosocial model of addiction have been the most widely used criteria to assess and diagnosis SMD. The Bergen social media addiction scale (BSMAS) based on Griffiths’ six criteria is a widely used instrument to assess the symptoms and prevalence of SMD in populations. This study aims to: (1) determine the optimal cut-off point for the BSMAS to identify SMD among Chinese adolescents, and (2) evaluate the contribution of specific criteria to the diagnosis of SMD.MethodStructured diagnostic interviews in a clinical sample (n = 252) were performed to determine the optimal clinical cut-off point for the BSMAS. The BSMAS was further used to investigate SMD in a community sample of 21,375 adolescents.ResultsThe BSMAS score of 24 was determined as the best cut-off score based on the gold standards of clinical diagnosis. The estimated 12-month prevalence of SMD among Chinese adolescents was 3.5%. According to conditional inference trees analysis, the criteria “mood modification”, “conflict”, “withdrawal”, and “relapse” showed the higher predictive power for SMD diagnosis.ConclusionsResults suggest that a BSMAS score of 24 is the optimal clinical cut-off score for future research that measure SMD and its impact on health among adolescents. Furthermore, criteria of “mood modification”, “conflict”, “withdrawal”, and “relapse” are the most relevant to the diagnosis of SMA in Chinese adolescents.
Another as the Other. Following the Dialogical Thought of Józef Tischner
Authors: Manikowski Maciej 
Published: May 2021

The world is a stage where everything is just a thing, even man. We discover it in an intentional opening. However, if we make a dialogical opening, man is no longer an object, but becomes a subject. Here we meet man as The Other and not as Another, an alien. Where do we encounter him? On the road, at the inn. What is needed? Setting a primal distance and entering into relation, in Martin Buber’s terms, or a dialogical opening and personification, entering into language or speech, according to Józef Tischner. On the road, at the inn where everyone is another, an alien, we become the other.
The Validity of Karol Wojtyła’s Philosophy Today
Authors: Hołub Grzegorz 
Published: May 2021

The article deals with the problem of the importance of Karol Wojtyła’s philosophy. He is shown as a thinker interested in the achievements of many philosophers throughout history, like Aristotle, St. Augustin, Thomas Aquinas, Immanuel Kant or Max Scheler. However, he is also presented as someone who undertook his own way of philosophizing focused on the human person. Therefore the article underlines Wojtyła’s dialogue with other philosophers at the time when he was developing his own philosophical standpoint. Moreover, his philosophy is shown as a discipline associated with real problems rather than with meta-philosophical ones. The article also discusses Wojtyła’s philosophy of the human person and how it can deal with anti-personalist tendencies in contemporary philosophy. Finally, the author considers some difficulties associated with the philosophy of Wojtyła and how it should be developed in the future.
On the possibilities of interpreting Neolithic pottery
Authors: Sebők Katalin 
Published: May 2021

The task of processing the multi-traditional ceramic material of the Late Neolithic settlement at Polgár-Csőszhalom-dűlő prenecessitated the development of a comprehensive approach by which all kinds of available information that may be detected in a ceramic object or in its find context are utilized and integrated into a closed, unbroken logical system interlinking objects and culture. This paper surveys the main topics and aspects of this theoretical structure, summarizing the author’s current understanding on the possible roles and functions of Neolithic pottery.
A New Method in Attribution? Attempts of the Employment of Geometric Morphometrics in the Attribution of Late Archaic Attic Lekythoi
Authors: Joháczi Szilvia 
Published: May 2021

In the Late Archaic - Early Classic period, the Attic ceramic industry was characterized by a kind of duality. On the one hand, the red-figure technique was flourishing, when Euphronios’, Douris’ or the Berlin Painter’s works represented the height of Greek vase painting. On the other hand, the market was also covered by large quantities of low-quality black-figure pottery. Not only in Athens, but even in the whole Ancient Mediterranean these mass-produced vessels emerge constantly, even from modern excavations. Therefore, in contrast to most vases of more talented painters they can be attached to an archaeological feature or layer. Due to their inadequate style, relatively few characteristics can be determined while looking at the painting. Thus, the manufacturing criteria, such as the details of the shapes, are more important in the attribution. In this paper, I study the late black-figure lekythoi of the Museum of Fine Arts in Budapest with the help of geometric morphometrics using 3D reconstructions.

Love Waves in a Viscoelastic Stratum: Explicit Expression for Complex Velocity as a Function of Frequency
Authors: Sharma Mohan D. 
Published: May 2021

ABSTRACT
Propagation of Love wave is considered in a two-layered stratum of isotropic viscoelastic solids. The complex dispersion equation for this wave is solved through a complex analysis technique. This gets an analytical expression for complex velocity, as a function of real frequency rather than the complex wavenumber. This complex (phase) velocity is used further to calculate the (complex) group velocity. Numerical example is solved to analyze the dispersion in speed and attenuation of the viscoelastic Love waves.
The recording of strong seismic motion
Authors: Blake A. 
Published: May 2021

AbstractIn designing a seismograph to measure strong motion it is important not to confine attention merely to the maximum acceleration or displacement of the earth motion; these are not sufficient to determine how much a building will be damaged. The fundamental problem is to measure the amount of motion associated with the periods to which the buildings respond. These periods are in the range from three-tenths of a second to three seconds. For this purpose a seismograph with a natural period of one second would be better than an instrument of either the accelerometer or displacement-meter type.
The Texas earthquake of August 16, 1931*
Authors: Byerly Perry 
Published: May 2021

SummaryThe travel-time curve of P for the Texas earthquake of August 16, 1931, shows that there is a definite break in the travel-time curve near Δ = 16°. This is interpreted as indicating a first-order discontinuity at a depth of about 300 kilometers. Another break in the travel-time curve at Δ = 25° is strongly suggested. Beyond Δ = 75° the curve has two branches, the lower following most existing curves, the upper following the Montana curve which latter seems to be a usual one for American earthquakes. This part of the curve is interpreted as indicating that the discontinuity at depth about 2,400 kilometers is a first-order one at which the speed of P waves drops discontinuously.From the direction of first motion on the records it is concluded that a sufficient source would have been motion on a fault of strike about N 35° W, the movement being up on the easterly side and down on the westerly side.The travel times of all waves read on the records are plotted on graphs. The scattering of all waves after P is marked.
Seismic surface waves and the crustal structure of the Pacific region*
Authors: Carder Dean S. 
Published: May 2021

summaryThe favorable location of Berkeley on the eastern margin of the Pacific makes possible a comparative study of surface waves coming directly from the epicenter to that station over paths that are purely Pacific or purely continental.Records of 378 earthquakes dating from November, 1910, to May, 1934, have been used in this study.Speeds and period of the initial impulses of Love waves have been measured and associated with wave-velocity. These waves show normal dispersion, the long waves having the greater speeds. Speeds over oceanic paths are higher than over continental paths, the difference diminishing with an increase in the wave-length. For short or long waves, they are about the same over all Pacific paths, but waves having intermediate periods (30 or 40 seconds) cross under the Aleutian deep faster than under the Polynesian Pacific.The data indicate for the crustal thicknesses under western North America and the Pacific the following approximate values: granite 20 kilometers, gabbro 40 kilometers, under western North America; basalt 25 kilometers, dunite 20 kilometers, under the Aleutian deep; basalt 30 kilometers, dunite 25 kilometers under Polynesia; and intermediate values under the remainder of the Pacific. A third discontinuity under the continent at depths somewhat greater than 60 kilometers is indicated. If the sub-Pacific is assumed to be single-layered, thicknesses of 35 to 45 kilometers form the best fit to the data. The thickness of the crust underlying the Pacific Islands is probably about 10 kilometers greater than that underlying the deeps of the North Pacific.Movements associated with Rayleigh waves apparently have their closest approach to theoretical conditions over central Pacific paths.The dominant periods in the coda are 8 to 9, 10, 13, and 16 seconds. The longer periods are dominant at the greater distances. The increase in period with distance is a discontinuous, step-like function.The structure underlying the Aleutian deep apparently is opaque to 13-second periods in the Rayleigh wave, and the central Pacific and possibly the Atlantic structure seems to be unfavorable in the transmission of waves having this period.Vibrations in the natural period or overtones thereof set up in the focal region being eventually transmitted as sympathetic vibrations to the region of the station seems to be a logical explanation for the dominant groupings in the coda. Should any section of the path be out of sympathy with a given period, this period would probably become subordinate if not lost.The natural period of a portion of the Arctic region, including Alaska, seems to be different from other parts of the world. The natural period of the San Francisco Bay region, or its dominant overtone, is observed to be about eight seconds.
Earthquakes instrumentally recorded in artesian wells*
Authors: Leggette R. M. , Taylor G. H. 
Published: May 2021

AbstractWater-level fluctuations produced by earthquakes have been instrumentally recorded in many observation wells. Such fluctuations are produced only in wells that penetrate water which is confined under pressure. Most of the instruments that produced these earthquake records are automatic water-stage recorders operating with floats on the water surface in a well. In such recording devices water must move into or out of the bottom of the well to produce records of fluctuation. Earthquake disturbances are rapid and oscillating and float recorders therefore do not quantitatively record such disturbances. During the earthquakes of March 12 and April 14, 1934, a recording pressure gage was in operation on an artesian well in Ogden Valley, Utah. The fluctuation of pressure recorded during these earthquakes was about 5.5 and 3.8 pounds per square inch, respectively. This instrument is so constructed that very little water moves into or out of the well when changes of hydrostatic pressure take place, and thus the rapidly oscillating changes in hydrostatic pressure that occur during earthquakes are recorded. This suggests a quantitative method of recording earthquakes that may yield data not given by present methods.
Experimentally determined dynamic shears in a sixteen-story model*
Authors: Jacobsen Lydik S. , Ayre Robert S. 
Published: May 2021

SummaryThe paper discusses the dynamic behavior of a 16-story building model representing an idealized office building. The model is subjected to “standardized” types of ground motion, and the dynamic shears between adjacent stories are measured. The rigidity of the first story is varied so that the effect of a “flexible” first story on the dynamic shears is demonstrated. It is concluded that flexibility in the first story decreases the dynamic shears everywhere in the building when the same degree of “tuning in” with the ground-motion frequency is postulated. Moreover, it is concluded that current practice design rules are in fair agreement with the shears that may be expected when the building is vibrating in or near its fundamental mode, but that current practice does not allow for shears due to the higher modes unless a comparatively flexible first story is used.
Near earthquakes in Central California*
Authors: Byerly Perry 
Published: May 2021

SummaryLeast-squares adjustments of observations of waves of the P groups at central and southern California stations are used to obtain the speeds of various waves. Only observations made to tenths of a second are used. It is assumed that the waves have a common velocity for all earthquakes. But the time intercepts of the travel-time curves are allowed to be different for different shocks. The speed of P̄ is found to be 5.61 km/sec.±0.05. The speed for S̄ (founded on fewer data) is 3.26 km/sec. ± 0.09. There are slight differences in the epicenters located by the use of P̄ and S̄ which may or may not be significant. It is suggested that P̄ and S̄ may be released from different foci.The speed of Pn, the wave in the top of the mantle, is 8.02 km/sec. ± 0.05. Intermediate P waves of speeds 6.72 km/sec. ± 0.02 and 7.24 km/sec. ± 0.04 are observed. Only the former has a time intercept which allows a consistent computation of structure when considered a layer wave. For the Berkeley earthquake of March 8, 1937, the accurate determination of depth of focus was possible. This enabled a determination of layering of the earth's crust. The result was about 9 km. of granite over 23 km. of a medium of speed 6.72 km/sec. Underneath these two layers is the mantle of speed 8.02 km/sec. The data from other shocks centering south of Berkeley would not fit this structure, but an assumption of the thickening of the granite southerly brought all into agreement.The earthquakes discussed show a lag of Pn as it passes under the Sierra Nevada. This has been observed before. A reconsideration of the Pn data of the Nevada earthquake of December 20, 1932, together with the data mentioned above, leads to the conclusion that the root of the mountain mass projects into the mantle beneath the surface layers by an amount between 6 and 41 km.
