Authors: Cobey Kelly D. , Lalu Manoj M , Skidmore Becky , Ahmadzai Nadera , Grudniewicz Agnes , Moher David 
Published: July 2018

Background: There is no standardized definition of what a predatory journal is, nor have the characteristics of these journals been delineated or agreed upon. In order to study the phenomenon precisely a definition of predatory journals is needed. The objective of this scoping review is to summarize the literature on predatory journals, describe its epidemiological characteristics, and to extract empirical descriptions of potential characteristics of predatory journals. Methods: We searched five bibliographic databases: Ovid MEDLINE, Embase Classic + Embase, ERIC, and PsycINFO, and Web of Science on January 2nd, 2018. A related grey literature search was conducted March 27th, 2018. Eligible studies were those published in English after 2012 that discuss predatory journals. Titles and abstracts of records obtained were screened. We extracted epidemiological characteristics from all search records discussing predatory journals. Subsequently, we extracted statements from the empirical studies describing empirically derived characteristics of predatory journals. These characteristics were then categorized and thematically grouped. Results: 920 records were obtained from the search. 344 of these records met our inclusion criteria. The majority of these records took the form of commentaries, viewpoints, letters, or editorials (78.44%), and just 38 records were empirical studies that reported empirically derived characteristics of predatory journals. We extracted 109 unique characteristics from these 38 studies, which we subsequently thematically grouped into six categories: journal operations, article, editorial and peer review, communication, article processing charges, and dissemination, indexing and archiving, and five descriptors. Conclusions: This work identified a corpus of potential characteristics of predatory journals. Limitations of the work include our restriction to English language articles, and the fact that the methodological quality of articles included in our extraction was not assessed. These results will be provided to attendees at a stakeholder meeting seeking to develop a standardized definition for what constitutes a predatory journal.

Cel pracyZawody pomocowe takie jak strażacy, policjanci wiążą się z narażeniem na ciężki stres, który może spowodować pogorszenie funkcjonowania i rozwój takich zespołów chorobowych, jak zespół stresu pourazowego PTSD. Celem pracy była ocena sposobu radzenia sobie ze stresem przez strażaków narażonych na ciężki stres, ocena występowania zespołu PTSD w badanej grupie strażaków, oraz korelacji ze sposobami radzenia sobie ze stresem.MetodaBadania przeprowadzono w grupie 147 polskich strażaków.. Do oceny sposobów radzenia sobie ze stresem zastosowano Kwestionariusz Radzenia Sobie w Sytuacjach Stresowych. Drugim zastosowanym narzędziem badawczym był Kwestionariusz do Pomiaru Zaburzenia po Stresie Traumatycznym (K-PTSD) w polskiej wersji językowej.WynikiWykazano, że strażacy najczęściej podejmują próby aktywnego radzenia sobie z napięciem stresowym. Natomiast najmniej chętnie stosują metody polegające na koncentrowaniu się na sobie i negatywnych przeżyciach emocjonalnych.WnioskiBlisko jedna trzecia badanych strażaków cierpiała z powodu objawów syndromu stresu pourazowego, a najczęściej stwierdzaną wśród nich strategią radzenia sobie ze stresem był styl skoncentrowany na unikaniu. Jednocześnie wiek okazał się być czynnikiem związanym z gotowością do podejmowania zachowań zaradczych wobec napięcia stresowego; starsi strażacy łatwiej podejmują zachowania zaradcze.

Cel pracyCelem pracy było zbadanie różnic między grupami osadzonych, wyodrębnionymi na podstawie kryterium jakości życia, pod względem sposobów radzenia sobie ze stresem.MetodaW celu weryfikacji hipotez badawczych zostały zastosowane następujące narzędzia badawcze: (1) Kwestionariusz Poczucia Jakości Życia autorstwa M. Straś Romanowskiej (2007) oraz (2) Kwestionariusz COPE autorstwa Carver, Scheier i Weintraub (1989).WynikiWyniki przedstawionych badań potwierdziły, że sposoby radzenia sobie ze stresem stosowane przez osoby osadzone są powiązane z jakością życia. Wniosek ten dotyczy zarówno wyniku ogólnego poczucia jakości życia, ale także wszystkich jego wymiarów: psychofizycznego, psychospołecznego, podmiotowego oraz metafizycznego. Zgodnie z zakładaną hipotezą osoby cechujące się wysokim poziomem ogólnej jakości życia, istotnie częściej niż osoby z niskim poziomem, preferują aktywne strategie radzenia sobie ze stresem, wśród których znalazły się takie strategie, jak: Aktywne radzenie sobie, Planowanie, Poszukiwanie wsparcia instrumentalnego, Poszukiwanie wsparcia emocjonalnego, Pozytywne przewartościowanie i rozwój. Podobny wniosek z niewielkimi modyfikacjami dotyczy również innych wymiarów jakości życia.WnioskiStosowanie zatem konstruktywnych sposobów radzenia sobie ze stresem, opartych na poszukiwaniu wsparcia, aktywności własnej w radzeniu sobie z problemami, wyciąganiu wniosków z błędnych wyborów życiowych wiąże się z wyższym poziomem jakości życia.

Published: July 2018

Abstract
The aim of this study was to develop V-shape compression socks that should exert graduated lateral compression around the leg. For the development of socks, three types of yarns: main yarn (MY), plaiting yarn (PY) and inlaid yarn (IY) were used. Each yarn contained spandex yarn as the core. Machine adjustments were optimized to achieve the special V-shaped compression socks according to size of the wooden leg. Eighteen socks samples were developed and quantified for pressure exertion at ankle and calf portions using the MST MKIV, Salzmann pressure measuring device. Consequently, only two socks samples were accepted, which had the pressure exertion values of 21 mmHg and 23 mmHg with graduation percentage of 73% and 80%, respectively.

Published: July 2018

Abstract
The article presents a comparative analysis of the yarns used for manufacturing hernia meshes. For the analysis, two different linear masses, 46 dtex and 72 dtex, of transparent and dyed yarns were used; the dye used in the yarns was adequate for their intended use. The DSC tests showed the influence of thermal treatment on the change of thermal properties of the yarns. At the same time, it was proved that the aforementioned treatment had a bearing on the changes of crystallinity degree. All types of yarns were also subjected to physicochemical tests required for all the materials used for the production of hernia meshes.

Published: July 2018

AbstractThe maturity of sophisticated numerical tools for predicting damage in composite materials has become a priority research area in aero- and underwater structures. This paper proposes a modeling approach to endeavor achieving high fidelity of mechanical behavior of composite materials subjected to high pressure applications. The strategy begins with numerical methods to design an alternative material for high pressure applications and to build a ladder with experimental observations when these composites are deployed for 600 bar pressure which take into account the relevant deformation, effective estimation of mechanical properties and failure mechanisms at different length scales. Coupon-shaped specimens with different hardener-epoxy ratios were manufactured to investigate the uniaxial tensile performance and the morphological studies were carried out in order to have a picture regarding the delamination and debonding behavior of the aforementioned composites. The further scope of this work involves a review of some notable micromechanic models and to establish the state-of-art together with insights for future development. Analytical models based on the mechanics of materials (MOM) approach and Mori-Tanaka (M-T) methods are shown to estimate the elastic response of composite materials. An attempt has been made to validate these finite-element predictions with experimental observations in order to secure the capability of a numerical framework. The outcome of our study also assures that these composites can be used in advanced structural applications under different conditions.
Transcendental Phenomenology and Unobservable Entities
Authors: Berghofer Philipp 
Published: July 2018

Abstract
Can phenomenologists allow for the existence of unobservable entities such as atoms, electrons, and quarks? Can we justifiably believe in the existence of entities that are in principle unobservable? This paper addresses the relationship between Husserlian transcendental phenomenology and scientific realism. More precisely, the focus is on the question of whether there are basic epistemological principles phenomenologists are committed to that have anti-realist consequences with respect to unobservable entities. This question is relevant since Husserl’s basic epistemological principles, such as the “principle of all principles,” seem to suggest that epistemic justification is limited to what can be originally given in the sense that if an object cannot be given in an originary presentive intuition, then one cannot be justified in believing that this object exists. It is the main aim of this paper to show (i) that interpretative reasons exist for not reading Husserl in such a way and (ii) that systematic reasons exist as to why phenomenologists should not subscribe to this criterion. I shall put forward a different criterion of justification that satisfies the spirit of Husserlian transcendental phenomenology and allows for justifiably believing in the existence of unobservable scientific entities.
Objectively Assessed Physical Activity in the Oldest Old Persons With Coronary Artery Disease
Authors: Strauch Stefanie , Hagströmer Maria , Bäck Maria 
Published: July 2018

Background and Purpose:
Accelerometer threshold values to detect physical activity intensity in the oldest old persons with coronary artery disease (CAD) are lacking as well as knowledge about their free-living physical activity behavior. The purpose of this study was 2-fold. (1) To assess the sensitivity and specificity of 3 existing intensity threshold values for ActiGraph accelerometers for the oldest old persons with CAD. (2) To assess free-living physical activity, applying the threshold values with the highest sensitivity and specificity for assessing at least moderate intensity, among these persons.

Methods:
In a cross-sectional design, a total of 24 persons with CAD, mean age 87.5 (3.7) years, participated in the study at a university hospital in Sweden. To assess the sensitivity and specificity of the existing threshold values, the participants walked at different speeds wearing the accelerometer at a pace corresponding to individualized perceived exertion at light, moderate, and high intensity according to the Borg Rating of Perceived Exertion Scale. For the free-living physical activity assessment, the persons wore the accelerometer for 7 consecutive days. The percentage agreement for light-, moderate-, and high-intensity threshold values, as well as receiver operating characteristic curves, was used to identify the sensitivity and specificity of the existing threshold values for moderate intensity.

Results and Discussion:
The threshold values for at least moderate intensity at 1041 counts per minute according to Copeland had the highest sensitivity (0.739) and specificity (0.609) to identify at least moderate intensity for the ActiGraph GT3X+ accelerometer. In a free-living setting, the oldest old persons with CAD spent 11 of 13.5 (81%) waking hours in a sedentary position and, of the 2.5 hours of being active, 19 minutes (2%) were at least at moderate intensity. Nine of 24 persons (38%) reached 20 minutes of moderate- to vigorous-intensity physical activity 3 days a week, according to guidelines for exercise-based cardiac rehabilitation.

Conclusions:
The existing threshold values according to Copeland had the highest sensitivity and specificity to identify at least moderate intensity and are valid for use in the oldest old persons with CAD. Using accelerometry as an objective measurement for physical activity can help further improve our understanding of free-living physical activity behavior and to assess relationships between free-living physical activity and health outcomes among the oldest old persons with CAD.

Abstract
Miranda, H, de Souza, JAAA, Scudese, E, Paz, GA, Salerno, VP, Vigário, PdS, and Willardson, JM. Acute hormone responses subsequent to agonist-antagonist paired set vs. traditional straight set resistance training. J Strength Cond Res 34(6): 1591–1599, 2020—The purpose of this study was to compare acute hormone responses and rating of perceived exertion (OMNI-Res) subsequent to the agonist-antagonist paired set (PS) vs. the traditional straight set (TS) resistance training method. Twelve recreationally trained men (25.7 ± 4.7 years, 173 ± 6.3 cm and 71.5 ± 6.6 kg) participated in the current study. After 10 repetition maximum (RM) load determination, each subject performed the following 2 experimental sessions in random order: TS session—3 sets of 10 repetitions at 85% of 10RM for the machine seated row and barbell bench press with 2-minute rest intervals between sets; and PS—3 sets of 10 repetitions with 85% of 10RM alternating machine seated row and barbell bench press for the total of 6 PSs with 2-minute rest intervals between sets. Total testosterone (TT), free testosterone (FT), cortisol, TT/cortisol ratio, growth hormone (GH), and blood lactate concentrations were measured before workout and immediately after workout and 15 and 30 minutes after workout. The OMNI-RES was recorded at the end of each set for both exercises within each session. Under the TS session, TT significantly increased immediately post-workout vs. the pre-workout time point. For the PS session, TT significantly decreased at 30-minute post-workout vs. the immediate post-workout time point, whereas, FT significantly increased immediately post-workout and 15-minute post-workout vs. the pre-workout time point. For the TS session, GH significantly increased immediately post-workout, and at the 15- and 30-minute post-workout time points vs. the pre-workout time point, respectively. For the PS session, GH was significantly increased immediately post-workout vs. the pre-workout time point. Blood lactate significantly increased at all post-workout time points vs. the pre-workout time point under both sessions. The cortisol and TT/cortisol ratio showed no differences between sessions. In conclusion, from an acute standpoint, the TS approach showed a tendency to cause greater disruption in hormone levels, despite the lack of significant differences vs. the PS approach at all time points. However, both strategies may promote similar acute hormone responses.

Abstract
Perrotta, AS, White, MD, Koehle, MS, Taunton, JE, and Warburton, DER. Efficacy of hot yoga as a heat stress technique for enhancing plasma volume and cardiovascular performance in elite female field hockey players. J Strength Cond Res 32(10): 2878–2887, 2018—This investigation examined the efficacy of hot yoga as an alternative heat stress technique for enhancing plasma volume percentage (PV%) and cardiovascular performance. Ten international caliber female field hockey players completed six 60-minute hot yoga sessions using permissive dehydration over 6 days, followed by a 6-day national team camp. Changes in PV% were examined throughout the intervention and postintervention period. A graded maximal exercise test was performed in a thermoneutral environment (23.2 ± 1.0° C) 24 hours before and 24 hours after intervention. Six days of hot yoga initiated a moderate state of hypovolemia (PV% = −3.5%, 90% confidence limit [CL] [−6.9 to −0.13]), trivial improvements in maximal aerobic power (V̇o
2max) (effect size [ES] = 0.06, 90% CL [−0.16 to 0.28]), and run time to exhaustion (ES = 0.11, 90% CL [−0.07 to 0.29]). Small meaningful improvements were observed in running speed (km·h−1) at ventilatory threshold (VT1) (ES = 0.34, 90% CL [−0.08 to 0.76]), VT2 (ES = 0.53, 90% CL [−0.05 to 1.1]), along with adaptations in the respiratory exchange ratio during high-intensity exercise (ES = –0.25, 90% CL [–0.62 to 0.12]). A large plasma volume expansion transpired 72 hours after intervention (PV% = 5.0%, 90% CL [1.3–8.7]) that contracted to a small expansion after 6 days (PV% = 1.6%, 90% CL [−1.0 to 4.2]). This investigation provides practitioners an alternative heat stress technique conducive for team sport, involving minimal exercise stress that can preserve maximal cardiovascular performance over periodized rest weeks within the yearly training plan. Furthermore, improvements in submaximal performance and a delayed hypervolemic response may provide a performance-enhancing effect when entering a 6-day competition period.

Abstract
Byrne, PJ, Moody, JA, Cooper, SM, Callanan, D, and Kinsella, S. Potentiating response to drop-jump protocols on sprint acceleration: drop-jump volume and intrarepetition recovery duration. J Strength Cond Res 34(3): 717–727, 2020—The purpose of this study was to investigate the postactivation potentiation response first to bounce drop jump (BDJ) volume; second, BDJ intrarepetition recovery duration and recovery duration between BDJs and 20-meter (including 5- and 10-m split times) sprint performance. The study was undertaken in 2 parts, the first part compared different volumes of BDJs and the second part compared different BDJ intrarepetition recovery periods. The effect of recovery periods between the BDJs and the subsequent 20-m sprints was examined in both parts 1 and 2 (15 seconds, 4, 8, and 12 minutes). Fourteen (mean ± SD: age = 20.83 ± 1.26 years; height = 1.77 ± 0.04 m; and mass = 74.89 ± 6.07 kg) (part 1) and 15 (mean ± SD: age = 20.64 ± 1.00 years; height = 1.78 ± 0.06 m; and mass = 75.67 ± 6.28 kg) (part 2) male collegiate and club hurling players volunteered to participate. A randomized cross-over design was used to compare BDJ volumes (1, 2, and 3 sets of 3 repetitions) and BDJ intrarepetition recovery time (15 vs. 60 seconds) after a warm-up followed by 2 baseline 20-m sprints. The results in part 1 reported a significant improvement in 5- and 10-m sprint time for 1 set of 3 BDJs between baseline and 4 minutes (5 m: −2.34%, p = 0.04, effect size [ES] = −0.043; 10 m: −1.42%, p = 0.03, ES = −0.35), and baseline and 12 minutes (5 m: −3.33%, p = 0.03, ES = −0.57; 10 m: −2.13%, p = 0.01, ES = −0.52). Part 2 reported a significant improvement in 5-m sprint time between baseline and 15 seconds (5 m: −3.38%, p = 0.01, ES = −0.83; 10 m: −2.07%, p = 0.02, ES = −0.58) after the BDJs. The findings support the use of 1 set of 3 BDJs using a 15-second intrarepetition recovery period to maximize 5-, 10-, and 20-m sprint performance after 15 seconds of recovery after the final BDJ in hurling players. The acute response to this BDJ protocol proves to be time efficient and effective in acutely improving sprint acceleration.
