Multiple meta-analyses may use similar search criteria and focus on the same topic of interest, but they may yield different or sometimes discordant results. The lack of statistical methods for synthesizing these findings makes it challenging to properly interpret the results from multiple meta-analyses, especially when their results are conflicting. In this paper, we first introduce a method to synthesize the meta-analytic results when multiple meta-analyses use the same type of summary effect estimates. When meta-analyses use different types of effect sizes, the meta-analysis results cannot be directly combined. We propose a two-step frequentist procedure to first convert the effect size estimates to the same metric and then summarize them with a weighted mean estimate. Our proposed method offers several advantages over existing methods by Hemming et al. (2012). First, different types of summary effect sizes are considered. Second, our method provides the same overall effect size as conducting a meta-analysis on all individual studies from multiple meta-analyses. We illustrate the application of the proposed methods in two examples and discuss their implications for the field of meta-analysis.

Having studied attitudes towards usage problems such as the notorious split infinitive or the ubiquitous literally in British English as part of my doctoral thesis, I was intrigued by the sheer lack of scientific studies investigating such attitudes. What was even more intriguing was to discover that the same field and the same usage problems seem to have received a different treatment in the United States of America. While my search for previously conducted usage attitude studies in Great Britain has largely remained fruitless, besides two notable exceptions which I will discuss in detail below (see Section 3), a similar search for American usage attitude studies resulted in a different picture. Considerably more such studies seem to have been conducted in the US than in Great Britain. On top of cultural and linguistic differences between these two nations, it seems as if they also hold different attitudes towards studying attitudes towards usage problems. Now the following question arises: why do we find such contradictory scientific traditions in these two countries? In this paper, I will provide an overview of a selection of American and British usage attitude studies. Taking into account differences between the American and British studies with regard to the number of usage problems studied, the populations surveyed and the methods applied, I will attempt to capture manifestations of two seemingly diverging attitudes towards the study of usage problems. By doing so, I will provide a possible explanation for the lack of attention being paid to usage attitudes in Great Britain.

Abstract In a recent work, Dai [1] searched for a variability in Newton’s constant G using the IGETS based gravitational acceleration measurements. However, this analysis, obtained from χ 2 minimization, did not incorporate the errors in the gravitational acceleration measurements. We carry out a similar search with one major improvement, wherein we incorporate these aforementioned errors. To model any possible variation in the gravitational acceleration, we fit the data to four models: a constant value, two sinusoidal models, and finally, a linear model for the variation of gravitational acceleration. We find that none of the four models provides a good fit to the data, showing that there is no evidence for a periodicity or a linear temporal variation in the acceleration measurements. We then redid these analyses after accounting for an unknown intrinsic scatter. After this, we find that although a constant model is still favored over the sinusoidal models, the linear variation for G is marginally preferred over a constant value, using information theory-based methods.

An online search for articles on the history of optometry and other healthcare fields is reported and is compared to a similar search conducted in 2007. A possible explanation for comparatively fewer articles on the history of optometry is explored. Brief comments are made on the significance of optometry history, along with suggestions on ways to enhance its study.

A family doctor, as well as a sexologist, gynecologist, in his medical practice encounters problems related to skin diseases significantly affecting the sense of femininity or masculinity. An example of such an issue, especially in gynecology of developmental age, is the problem of skin changes associated with androgenization syndromes. Typical dermatological diseases are sometimes associated with enormous pain, not only physical, but also mental, resulting from the fact that skin disease processes significantly disfigure the body, lower self-esteem and significantly affect the sexual sphere. Selected aspects related to the holistic approach to the issue of pain and suffering, also related to skin lesions, are presented. This issue, like all medical fields, is a source of philosophical reflection. It is inseparable from psychodermatology. The experience of the SARS-CoV-2 coronavirus pandemic, taking into account skin lesions, also prompts a similar search.

AbstractMoving in and out of small cavelike structures is a common daily activity of Colostethus palmatus. Such sites are used for shelter and spawning. Therefore, cave quality is important to survival and reproductive success. The frogs' association with caves was studied in a 24-cave communal paludarium. Adult frogs recognised cave quality, and chose large damp caves for spawning, but large, wet and dark caves were preferred for shelter, while small ones were used less or ignored. The search time needed to find an available cave gradually shortened over trials, reaching a minimum in about eight days, indicating that frogs learned cave position. Males and females had similar search times. Frogs less familiar with the test area had longer initial search times than frogs with more experience, but achieved equally short search times after about eight days. In conjunction with previous findings the results suggest that visual cues are important in habitat choice and spatial learning, and that territorial and reproductive behaviour are intimately associated with learning performance.

With rapid development of search engine users, the auto bidding for search engine keywords is stealthily rising and such kind of service is now essentially being conducted on the majority of existing search engines. For merchants, users and even the search engine service suppliers, auto bidding is of many advantages, which is also thought it has brought forth serious phenomenon of bad faith in terms of such kind of similar search websites, leading to a crisis of confidence. This text is intended to give it a full analysis on the various problems of bad faith resulted from the auto bidding for search engine keywords. And it is in consideration of the huge controlling forcing and social influence of the search engines, there lies a great need in strengthening the closer government supervision. While guaranteeing a healthy and orderly development of search engine, our purpose is to render back an honest and clean searching environment of internet information to the public.

Brown-headed cowbirds ( Molothrus ater ) are obligate brood parasites. Only females search for host nests and they find host nests one or more days before placing eggs in them. Past work has shown that females have a larger hippocampus than males, but sex differences in spatial cognition have not been extensively investigated. We tested cowbirds for sex and seasonal differences in spatial memory on a foraging task with an ecologically relevant retention interval. Birds were trained to find one rewarded location among 25 after 24 h. Females made significantly fewer errors than males and took more direct paths to the rewarded location than males. Females and males showed similar search times, indicating there was no sex difference in motivation. This sex difference in spatial cognition is the reverse of that observed in some polygynous mammals and is consistent with the hypothesis that spatial cognition is adaptively specialized in this brood-parasitic species.

Presently, adults can exploit a vast amount of online health information for solving relatively complex health problems. This study examined the performance of 60 adults ranging in age from 18-82 years on a complex online health information search task. Measures of search time, amount of search, search accuracy, and six cognitive abilities were obtained. The older participants exhibited similar search accuracy, significantly less amount of search, and significantly longer time to complete the problem compared to the younger participants. For the younger participants having higher cognitive ability typically translated into significantly better search accuracy and greater amount of search accomplished. For the older participants, only processing speed significantly distinguished the lower and higher ability older adults on search accuracy and none of the ability measures differentiated these participants on amount of search. These differences and their implications are discussed in the context of supporting older online health information seekers.
