TL;DR: In this paper, an analysis of the timing data of the pulsar B1642-03, collected over a span of 30 years between 1969 and 1999, is presented, with the timing residuals exhibiting cyclical changes with amplitude varying from 15 to 80 ms and spacing of maxima varying from 3 to 7 yr.
Abstract: We present an analysis of the timing data of the pulsar B1642-03, collected over a span of 30 years between 1969 and 1999. During this interval, the timing residuals exhibit cyclical changes with amplitude varying from 15 to 80 ms and spacing of maxima varying from 3 to 7 yr. Interpretation of these observed cyclical changes in terms of free precession suggests a wobble angle of about 08.

TL;DR: Data is reported supporting the broader claim that shame is a basic part of human biology, and that shame’s match to audience devaluation is a design feature crafted by selection and not a product of cultural contact or convergent cultural evolution.
Abstract: Human foragers are obligately group-living, and their high dependence on mutual aid is believed to have characterized our species' social evolution. It was therefore a central adaptive problem for our ancestors to avoid damaging the willingness of other group members to render them assistance. Cognitively, this requires a predictive map of the degree to which others would devalue the individual based on each of various possible acts. With such a map, an individual can avoid socially costly behaviors by anticipating how much audience devaluation a potential action (e.g., stealing) would cause and weigh this against the action's direct payoff (e.g., acquiring). The shame system manifests all of the functional properties required to solve this adaptive problem, with the aversive intensity of shame encoding the social cost. Previous data from three Western(ized) societies indicated that the shame evoked when the individual anticipates committing various acts closely tracks the magnitude of devaluation expressed by audiences in response to those acts. Here we report data supporting the broader claim that shame is a basic part of human biology. We conducted an experiment among 899 participants in 15 small-scale communities scattered around the world. Despite widely varying languages, cultures, and subsistence modes, shame in each community closely tracked the devaluation of local audiences (mean r = +0.84). The fact that the same pattern is encountered in such mutually remote communities suggests that shame's match to audience devaluation is a design feature crafted by selection and not a product of cultural contact or convergent cultural evolution.

TL;DR: Women’s preferences for more masculine looking men are stronger in countries with higher sociosexuality and where national health indices and human development indices are higher, while no associations were found between preferences and indices of intra-sexual competition.
Abstract: The strength of sexual selection on secondary sexual traits varies depending on prevailing economic and ecological conditions. In humans, cross-cultural evidence suggests women’s preferences for men’s testosterone dependent masculine facial traits are stronger under conditions where health is compromised, male mortality rates are higher and economic development is higher. Here we use a sample of 4483 exclusively heterosexual women from 34 countries and employ mixed effects modelling to test how social, ecological and economic variables predict women’s facial masculinity preferences. We report women’s preferences for more masculine looking men are stronger in countries with higher sociosexuality and where national health indices and human development indices are higher, while no associations were found between preferences and indices of intra-sexual competition. Our results show that women’s preferences for masculine faces are stronger under conditions where offspring survival is higher and economic conditions are more favorable.

TL;DR: In this article, the authors reviewed the anaerobic digestion of food waste, the composition of its digestate and trends in the treatment of ADFE with emphasis on treatment using microalgae.
Abstract: Food waste constitutes a significant portion of waste in the world. Indeed, it is estimated that about one-third of edible human food is wasted globally. Anaerobic digestion has been identified as a promising technology for the treatment of food waste as it generates a significant amount of energy and can remove a substantial portion of the organics. However, this process has not been adequately applied due to technical and economic challenges. Most importantly, anaerobic digestion of food waste produces waste in the form of Anaerobic digestate food effluent (ADFE), with high amounts of nutrient such as ammonium (up to 3000 mg L−1 NH3-N). It has been established that this effluent can be used as a substrate for the cultivation of microalgae allowing both a means of its treatment and its possible valorization. This paper reviews the anaerobic digestion of food waste, the composition of its digestate and trends in the treatment of ADFE with emphasis on treatment using microalgae. Potential microalgal cultivation methods applicable to the treatment of anaerobic digestate, especially ADFE, and possible optimization of the cultivation methods are also reviewed critically. Further, understanding of the cultivation of microalgae in ADFE is required to aid in better design of its treatment process and valorization to improve its economics.

TL;DR: This paper measured marital satisfaction and several factors that might potentially correlate with it based on self-report data from individuals across 33 countries and introduced the raw data available for anybody interested in further examining any relations between them and other country-level scores obtained elsewhere.
Abstract: Forms of committed relationships, including formal marriage arrangements between men and women, exist in almost every culture (Bell, 1997). Yet, similarly to many other psychological constructs (Henrich et al., 2010), marital satisfaction and its correlates have been investigated almost exclusively in Western countries (e.g., Bradbury et al., 2000). Meanwhile, marital relationships are heavily guided by culturally determined norms, customs, and expectations (for review see Berscheid, 1995; Fiske et al., 1998). While we acknowledge the differences existing both between- and within-cultures, we measured marital satisfaction and several factors that might potentially correlate with it based on self-report data from individuals across 33 countries. The purpose of this paper is to introduce the raw data available for anybody interested in further examining any relations between them and other country-level scores obtained elsewhere. Below, we review the central variables that are likely to be related to marital satisfaction
