Most previous research has demonstrated that receiving ability-focused praise negatively affects intrinsic motivation following failure. Surprisingly, a recent study showed that ability-focused praise affects not only the praisee but also the person offering praise, that is, the praiser. However, evidence of the effects on the praiser is quite limited, despite the utility of praise in education. Therefore, the present study employed face-to-face interaction to advance the knowledge of the effects of praise on the praiser. Two experiments were conducted in which (...) undergraduate participants praised a research confederate. We measured attentional engagement using an eye-tracker as a behavioral indicator of intrinsic motivation, as well as self-reported task enjoyment. To estimate the effect of praise, we combined the results of two experiments and conducted a Bayes factor meta-analysis. The results showed that in the ability praise group, participants’ attentional engagement in a task was significantly lower than in the control group. The present finding indicates that ability-focused praise negatively affects the praiser’s intrinsic motivation and suggests that praise should be used with caution in social and educational contexts.

Replication forks inevitably stall at damaged DNA in every cell cycle. The ability to overcome DNA lesions is an essential feature of the replication machinery. A variety of specialized polymerases have recently been discovered, which enable cells to replicate past various forms of damage by a process termed translesion synthesis. Alternatively, homologous recombination can be used to restart DNA replication across the lesion. Genetic and biochemical studies have shed light on the impact of these two post‐replication repair pathways in bacteria (...) and yeast. In vertebrates, however, a genetic approach to study post‐replication repair has been compromised because many of the genes involved appear to be essential for embryonic development. We have taken advantage of the chicken cell line DT40 to perform a genetic analysis of translesion synthesis and homologous recombination and to characterize genetic interactions between these two pathways in vertebrates. In this article, we aim to summarize our current understanding of post‐replication repair in DT40 in the perspective of bacterial, yeast and mammalian genetics.

Ecological developmental biology (eco‐devo) explores the mechanistic relationships between the processes of individual development and environmental factors. Recent studies imply that some of these relationships have deep evolutionary origins, and may even pre‐date the divergences of the simplest extant animals, including cnidarians and sponges. Development of these early diverging metazoans is often sensitive to environmental factors, and these interactions occur in the context of conserved signaling pathways and mechanisms of tissue homeostasis whose detailed molecular logic remain elusive. Efficient methods for (...) transgenesis in cnidarians together with the ease of experimental manipulation in cnidarians and sponges make them ideal models for understanding causal relationships between environmental factors and developmental mechanisms. Here, we identify major questions at the interface between animal evolution and development and outline a road map for research aimed at identifying the mechanisms that link environmental factors to developmental mechanisms in early diverging metazoans.Also watch the Video Abstract.

Climate dynamics and trends have significant environmental and socioeconomic impacts; however, in the Benin Republic, they are generally studied with diverse statistical methods ignoring the nonstationarity, nonlinearity, and self-similarity characteristics contained in precipitation time series. This can lead to erroneous conclusions and an unclear understanding of climatic dynamics. Based on daily precipitation data observed in the six synoptic stations of Benin Republic, in the period from 1951 to 2010, we have proposed determining the local trends of precipitations, investigating precipitation nonlinear (...) dynamics, and assessing climatic shift in the study period by Ensemble Empirical Mode Decomposition and Multifractal Detrended Fluctuation Analysis method. To overcome the detrending issue in the standard MFDFA method, the EEMD algorithm is embedded into the MFDFA. The study period is subdivided into three subperiods: 1951–1970, 1971–1990, and 1991–2010. Intrinsic Mode Functions are obtained according to the climatic region in which the stations are located. Results show that precipitation variation is significantly governed by the five first IMFs, in which oscillation periods vary from 1 to 25 days. The trend curves decrease at all the synoptic stations, and their slope values vary accordingly to the subperiods. Referring to the values of the multifractal spectrum parameters, α 0, and the width of the spectrum w, consistent changes are observed regardless of the subperiods and the concerned stations. The spatial and temporal variability of precipitation indicates that the multifractal properties are good indicators for assessing changes in precipitation dynamics, and the changes in their features could be explained by the global change than by the local climate variation. Despite the observed differences in multifractal spectra properties from the three subperiods, it is not possible to verify the subdivision of 1951–2010 in three subperiods as it is done by previous studies in West Africa. Our findings can be used in the validation of global and regional climate models since a valid model should explain empirically detected scaling properties in observed data. (shrink)

Walter Ong points out that no one can write naturally, because writing is a completely artificial technique we need to acquire through education. The technology of literacy as writing letters begets a dividing line between “literates” and “illiterates,” since literacy cannot be acquired otherwise. When we review the early history of literacy, we notice that letter-writing was a specialized technology, and that in its center resided a small number of elites who could write. Thereafter, in the Modern Era, the center (...) of discussion on literacy turned to the issue of the illiterate masses, mainly on how to bring them to literacy through school education. As the interest in popularizing literacy increased, though, another kind of increased interest arose: the interest in literacy education for blind people. On purpose or not, blind people had been excluded or alienated from literature and/or letter-based culture. However, the stronger the power exerted to exclude blind people, the more blind people aspired to write/read letters. Such aspiration and attempts to write/read letters in their own way may establish a distinct touch-centered world of letters and literacy and, importantly, may relativize its sight-centered world counterpart. If so, how will such a practice revise sight-centered literacy and open new horizons? I would like to consider this topic by reviewing its historical background and examining a case of writing practice by Kuzuhara Kôtô, a blind musician, in 19th century Japan. (shrink)

This paper discusses the contents and roles of the bulletin Giat, a community-based periodical published in Jakarta by a Koto Gadang foundation to support development in Koto Gadang, West Sumatra. Giat played a role as a communication medium linking people from Koto Gadang who lived outside their home area to their original villages. In describing and analysing the bulletin, I explore its content and focus on its collecting of funds for the clean water pipeline project in Koto Gadang and on (...) its distribution of information, especially information about Minangkabau customary law, culture, literature, and the women’s movement. The bulletin also facilitated the sharing of family news among people from Koto Gadang in the village and the rantau. Giat became a medium for maintaining interpersonal connections and accommodated initiatives to develop the village. It is shown that, as a community-based publication, Giat played a role in developing village infrastructure as well as its social and cultural fields. (shrink)
