At the beginning of the development of meta-analysis, understanding the role of moderators was given the highest priority, with meta-regression provided as a method for achieving this goal. Yet in current practice, meta-regression is not as commonly used as anticipated. This paper seeks to understand this mismatch by reviewing the history of meta-regression methods over the past 40 years. We divide this time span into four periods and examine three types of methodological developments within each period: technical, conceptual, and practical. Our focus is broad and includes development of methods in the fields of education, psychology, and medicine. We conclude the paper with a discussion of five consensus points, as well as open questions and areas of research for the future.

Pelvic organ prolapse has a mixed aetiology – hereditary and acquired. During last decade, the role of genetics in POP becomes profoundly obvious. women with a family history of prolapse are at an increased risk of prolapse refractory to treatment. Careful literature review from the past studies reveals that several genetic mutations have been shown to correlate with increased prolapse susceptibility. These mutations can result in disordered collagen metabolism, which weaken the fascial support of the pelvic organs. This prompt us to undertake the above study, look more into genetic discrepancies and pelvic organ prolapse contemporary studies relate to this topic shows that Collagen is playing a major role in pelvic floor supportive structures. However role of single nucleotide polymorphism (SNP) of the COL1A1 or COL3A1 or COL18A1 genes remain controversial relate to pelvic organ prolapse. Some studies and meta-analysis found a strict correlation between these genetic defects and POP.

This article investigates the ways in which the work of The Body Politic (TBP), the first major lesbian and gay newspaper in Canada, comes to be commemorated in queer publics and how it figures in the memories of those who were involved in producing the paper. In revisiting a critical point in the history of TBP from 1985 when controversy erupted over race and racism within the editorial collective, this discussion considers the role of memory in the reproduction of whiteness and in the rupture of standard narratives about the past. As the controversy continues to haunt contemporary queer activism in Canada, the productive work of memory must be considered an essential aspect of how, when and for what reasons the work of TBP comes to be commemorated. By revisiting the events of 1985 and by sifting through interviews with individuals who contributed to the work of TBP, this article complicates the narrative of TBP as a bluntly racist endeavour whilst questioning the white privilege and racially-charged demands that undergird its commemoration. The work of producing and preserving queer history is a vital means of challenging the intentional and strategic erasure of queer existence, but those who engage in such efforts must remain attentive to the unequal terrain of social relations within which remembering forms its objects.

The Relationship

This systematic review aimed to find attitudes toward Altruistic and Game-playing love styles across individualistic and collectivistic cultures. Addressing major moderators concerning Altruistic and Game-playing love styles are the secondary objectives of this review. This review included 102 articles comprising samples from 37 countries (N = 41997). The findings of this meta-analysis show that there is a collectivistic and individualistic difference in Game-playing but not in the Altruistic love style. Collectivistic and individualistic cultures, on average, demonstrate the same perception concerning the Altruistic love style, whereas collectivistic culture shows the Game-playing love style more strongly. To explain the role of moderators in key measures, the subgroup analysis and meta-regression show that both Game-playing and Altruistic love styles decline by increasing the length of the relationship. Likewise, having children affects these love styles such that the Altruistic love style is improved, and the Game-playing love style is reduced by the presence of children in families.

Kosovo’s Constitutional Court has played a role of paramount importance in the country’s recent history. The author uses a comparative analysis to discuss the role of the Court in light of the work and history of other European constitutional courts. This approach sheds light on the Court’s current role by analyzing Kosovo’s constitutional history, which shows that there has been a radical break with the past. This approach reveals the fact that Kosovo’s current Constitution does not reflect the material culture of the society of Kosovo. This radical break with the past is a result of the country’s tragic history, in which case the fight for constitutionalism means a fight for human dignity. In this battle for constitutionalism, the Court has been given very broad jurisdiction and a role to play in paving the way for Kosovo to move toward Euro-Atlantic integration in all spheres of life. Before reaching this conclusion, the author discusses the specificities of Kosovo’s transition, comparing it with other former communist countries. Among the specific features of constitutionalism in Kosovo are the role and position of the international community in the process of constitution-making and the overall design of constitutional justice in Kosovo. Throughout the article, a conclusion emerges that puts Kosovo’s Constitutional Court at the forefront of the fight for the rule of law and constitutionalism of liberal Western provenance.

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.

The role of Venus and Mercury transits is crucial to know the past history of the solar diameter. Through the W parameter, the logarithmic derivative of the radius with respect to the luminosity, the past values of the solar luminosity can be recovered. The black drop phenomenon affects the evaluation of the instants of internal and external contacts between the planetary disk and the solar limb. With these observed instants compared with the ephemerides the value of the solar diameter is recovered. The black drop and seeing effects are overcome with two fitting circles, to Venus and to the Sun, drawn in the undistorted part of the image. The corrections of ephemerides due to the atmospheric refraction will also be taken into account. The forthcoming transit of Venus will allow an accuracy on the diameter of the Sun better than 0.01 arcsec, with good images of the ingress and of the egress taken each second. Chinese solar observatories are in the optimal conditions to obtain valuable data for the measurement of the solar diameter with the Venus transit of 5/6 June 2012 with an unprecedented accuracy, and with absolute calibration given by the ephemerides.

AbstractOver the past 10 years, we (the Purdue Stuttering Project) have implemented longitudinal studies to examine factors related to persistence and recovery in early childhood stuttering. Stuttering develops essentially as an impairment in speech sensorimotor processes that is strongly influenced by dynamic interactions among motor, language, and emotional domains. Our work has assessed physiological, behavioral, and clinical features of stuttering within the motor, linguistic, and emotional domains. We describe the results of studies in which measures collected when the child was 4 to 5 years old are related to eventual stuttering status. We provide supplemental evidence of the role of known predictive factors (e.g., sex and family history of persistent stuttering). In addition, we present new evidence that early delays in basic speech motor processes (especially in boys), poor performance on a nonword repetition test, stuttering severity at the age of 4 to 5 years, and delayed or atypical functioning in central nervous system language processing networks are predictive of persistent stuttering.

  Most epidemiological studies focus on the direct causes of diseases while wider, social causal factors are ignored. This paper briefly highlights the history of major epidemics and the role of Anthropocene and Capitalocene for the emergence and reemergence of pandemics like COVID-19. Books, journal articles, and statistics offer information that can explain the phenomena. A historical inquiry can inform us about the fundamental causes of pandemics. Human security and ecology are intertwined, and the global effect of pandemics responded to at the national level is inadequate. The lessons from the past and present help us devise effective ethically and socially appropriate strategies to mitigate the threats. If the present crisis is not taken seriously at the global level, the world has to face more difficult challenges in years to come.
