Abstract. The ego depletion effect has been examined by over 300 independent studies during the past two decades. Despite its pervasive influence, recently this effect has been severely challenged and asserted to be a fake. Based on an up-to-date meta-analysis that examined the effectiveness of each frequently used depleting task, we preregistered the current experiment with the aim to examine whether there would be an ego depletion effect when the Stroop task is used as the depleting task. The results demonstrated a significant ego depletion effect. The current research highlights the importance of the depleting task’s effectiveness. That is to say, the “ego” could be “depleted,” but only when initial exertion is “depleting.”

Neonatal imitation is a cornerstone in many theoretical accounts of human development and social behavior, yet its existence has been debated for the past 40 years. To examine possible explanations for the inconsistent findings in this body of research, we conducted a multilevel meta-analysis synthesizing 336 effect sizes from 33 independent samples of human newborns, reported in 26 articles. The meta-analysis found significant evidence for neonatal imitation ( d = 0.68, 95% CI = [0.39, 0.96], p < .001) but substantial heterogeneity between study estimates. This heterogeneity was not explained by any of 13 methodological moderators identified by previous reviews, but it was associated with researcher affiliation, test of moderators ( QM) (15) = 57.09, p < .001. There are at least two possible explanations for these results: (a) Neonatal imitation exists and its detection varies as a function of uncaptured methodological factors common to a limited set of studies, and (2) neonatal imitation does not exist and the overall positive result is an artifact of high researcher degrees of freedom.

Abstract Nowadays venous VTE represents an important perioperative and postoperative complication in patients undergoing elective Major Orthopedic Surgery (MOS). There are significant discrepancies between clinical practice, international recommendations, and published guidelines. Although thromboembolic events may be less common these days than in the past, they can still lead to serious medical complications. Therefore, most patients undergoing MOS procedures are provided with one of the thromboprophylactic treatments. The optimum timing of LMWH administrations remains debated. Customized structured electronic searches in PubMed and Cochrane database. Meta-Analysis, Randomized Controlled Trials, Systematic Reviews on different strategies of the use of LMWH for MOS. Studies on prophylactic regimens showed that subcutaneous LMWH plays a key role in the management of thromboprophylaxis in MOS. However, some controversies still stand. Among those most relevant, it remains unclear whether to start thromboprophylaxis before or after MOS to better balance the risks of clotting and bleeding. With regards to different times of LMWH administration, there is no convincing evidence that starting prophylaxis 12 hours preoperatively is associated with lower risks of VTE compared to prophylaxis started 12 to 24 hours postoperatively. Furthermore, it seems that the most safe and efficient LMWH regimen is the one called “Just-in-time” (LMWH started 6 hours post-op).

Over the past few years, there has been an increase in the number of studies reporting on various aspects of the Atraumatic Restorative Treatment (ART) approach. Five randomized clinical trials in which ART restorations with glass ionomers were compared with amalgam restorations in permanent teeth for a maximum period of 3 yrs constituted the database. This meta-analysis divided the publications into ‘early’ (1987–1992) and ‘late’ (1995-) studies on the basis of improvements in the approach. The analysis showed that, in the ‘early’ studies, single-surface amalgam restorations survived statistically significantly longer than comparable ART restorations after 1, 2, and 3 yrs. This trend did not continue into the late group of studies; no statistically significant difference between the 2 types of restorations was found. Based on the available data, it appears that there is no difference in survival results between single-surface ART restorations and amalgam restorations in permanent teeth over the first 3 yrs.

Актуальность предпринятого исследования обусловлена тем, что причастие в современном осетинском языке не привлекало активного внимания ученых, имеются лишь общие описания причастий, а специальные исследования, посвященные причастиям, практически отсутствуют. Представляется интересным и актуальным сравнение системы причастий и их грамматических особенностей в осетинском и русском языках. Этот интерес обусловлен принадлежностью сопоставляемых языков к общей индоевропейской семье языков, а также тесным их взаимодействием в условиях двуязычия, что, очевидно, может отразиться и на системе причастий. Научная новизна данной статьи заключается в том, что в ней исследуются грамматические особенности всех разрядов причастий в осетинском языке в сопоставлении с русским языком. На основании проведенного анализа установлено, что в современном осетинском языке система причастий включает пять разрядов, разнообразных в своих грамматических проявлениях, в степени регулярности, в склонности переходить в состав других частей речи. Выявлены наиболее значительные отличия осетинских причастий от русских: существование причастий будущего времени в системе осетинского языка, отсутствие у причастий показателей времени и залога, а также именных грамматических категорий (падежа, числа, рода). Установлено также, что в осетинском языке категория вида в большей степени управляет категорией времени, в силу чего несовершенный вид причастий предполагает только настоящее время, а совершенный только прошедшее отсутствует четкая залоговая оппозиция причастий в осетинском языке. Определено также, что осетинские причастия не имеют членных (полных) форм, но функционируют в роли и сказуемого, и определения, хотя в большей степени тяготеют к предикативной роли. В осетинском языке причастия гораздо менее употребительны сравнительно с причастиями в русском языке и чаще вступают в отношения грамматической омонимии с другими частями речи. The relevance of the undertaken study is determined by the fact that participles in the modern Ossetian language are still insufficiently studied. There are only the most general descriptions of grammar features of participles. The comparison of the system of participles and their grammar features seems interesting and actual, especially considering the fact that the Ossetian and Russian languages belong to different groups of the Indo-European language family. Furthermore, in the context of bilingualism the Russian and Ossetian languages interact actively and that can affect the system of participles. The scientific novelty of the article is determined by the fact that it examines the grammatical features of all categories of participles in the Ossetian language in comparison with the Russian language. The conducted research allowed to elicit five categories in the system of participles in the modern Ossetian language. The analysis of the results showed the participles are diverse in their grammatical characteristics, in the degree of regularity, and in the tendency to transition into other parts of speech. The research defined the most significant differences between Ossetian and Russian participles: existence of future participles in the system of the Ossetian language absence of adjectival grammar categories of gender, number and case as well as formal markers of tense and voice in Ossetian participles. The tense category in Ossetian subordinates to the aspect category to a far greater extent therefore the imperfective aspect of participles accepts the present tense forms only, while perfective acts in the past tense forms Ossetian participles lack explicit voice opposition. Ossetian participles do not have full forms, but they can have syntactic functions of both the predicate and the attribute in a sentence, although the predicative function is more typical for them. Participles in the Ossetian language are much less common compared to participles in Russian and are more disposed to conversion (transition to the category of nouns, verbal adverbs, adjectives, words of the state category).

AbstractRecent concerns on increased incidence of myocardial infarction and stroke on administration of calcium and vitamin D supplements have alarmed the physicians about safety of these drugs. Although both calcium and vitamin D have been shown in the past to have beneficial effect on cardiovascular disease status through lowering of harmful lipids, these findings have been contradicted by some recent meta-analysis and randomized controlled trials that have shown no beneficial or in some cases a deteriorating effect of these supplements on lipid levels. In particular, calcium supplementation has been associated more with increased incidence of cardiovascular morbidity than vitamin D, but the convincing proof is still lacking. Here we have highlighted the results of some significant studies that might impact the prescription of these drugs.
