Methods sections are often missing essential details. Methodological shortcut citations, in which authors cite previous papers instead of describing the method in detail, may contribute to this problem. This meta-research study used 3 approaches to examine shortcut citation use in neuroscience, biology, and psychiatry. First, we assessed current practices in more than 750 papers. More than 90% of papers used shortcut citations. Other common reasons for using citations in the methods included giving credit or specifying what was used (who or what citation) and providing context or a justification (why citation). Next, we reviewed 15 papers to determine what can happen when readers follow shortcut citations to find methodological details. While shortcut citations can be used effectively, they can also deprive readers of essential methodological details. Problems encountered included difficulty identifying or accessing the cited materials, missing or insufficient descriptions of the cited method, and shortcut citation chains. Third, we examined journal policies. Fewer than one quarter of journals had policies describing how authors should report previously described methods. We propose that methodological shortcut citations should meet 3 criteria; cited resources should provide (1) a detailed description of (2) the method used by the citing authors', and (3) be open access. Resources that do not meet these criteria should be cited to give credit, but not as shortcut citations. We outline actions that authors and journals can take to use shortcut citations responsibly, while fostering a culture of open and reproducible methods reporting.

Climate change increases the risk of coffee yield due to the genotype-dependent effects of water deficit on coffee physiology. The goal of this research was to evaluate how water deficit altered the physiological and growth characteristics of arabica coffee (Coffea arabica L.). Water status, photosynthetic response to CO2 intercellular concentration (A/Ci curves) and growth parameters were evaluated in seedlings of four genotypes (Catimor ECU 02, Cavimor ECU, red Caturra and Sarchimor 4260). Most of the physiological traits evaluated differed significantly among genotypes. Between control and water deficit plants, significant variations occurred in the A/Ci parameters, showing a wide range of values for net photosynthetic rate, stomatal conductance, and water use efficiency, with decreases ranging from 4 to 74%. Maximum electron transport rate through photosystem II, highest rate of RuBisCO carboxylation, and triose phosphate utilization rate were all strongly decreased by water deficit 61% (red Caturra and Sarchimor 4260), followed by Cavimor ECU (35%) and Catimor ECU 02 (24%). Differences in response to water deficit among genotypes suggest possible genotypic differences in tolerance. The results indicated that Catimor ECU 02 and Cavimor ECU were less sensitive to water deficit, while red Caturra and Sarchimor 4260 were the most susceptible.

Plain Language summary In Rwanda, youth who are having sex use family planning less than married women. This study involved asking family planning providers and adults what they think about youth using family planning. Data for this study was collected in 2018, and included 32 interviews with adult family planning users and eight group discussions with family planning providers in two areas of Rwanda. The findings show that Rwandans believe youth should not have sex before they are married. Family planning providers do provide youth with services; however, they often push stopping sexual activity, offer a smaller selection of family planning methods, and exaggerate risks associated with sex and family planning use. Family planning providers support youth by honoring their need for privacy, keeping their secrets, and providing fast services so fewer people see them at the clinic. Providers like to help adolescents in youth corners, which are special spaces within health facilities just for youth. Importantly, adult women who use family planning want youth in their community to be able to use family planning, too. In order to respond to the issues raised, the Rwandan government can start conversations in villages and more broadly about the need for youth to have access to family planning. The government should also teach family planning providers and anyone who comes into contact with youth to offer helpful and friendly services. Setting up spaces for adults to talk with family planning providers about youth access to family planning could also contribute to fewer barriers to services for adolescents.

Plain language summary Family planning use increased from 17 to 53% in Rwanda in between 2005 and 2015. The purpose of this study is to understand the roles of two types of family planning workers in providing family planning services, how those providers work together to achieve the goal to provide public services, and how the Rwandan health system includes family planning services in a variety of other types of health services. To achieve the study purpose, 32 women with experience using modern methods of contraception were interviewed. In addition, 88 providers participated in eight group discussions to discuss these topics. The results from the interviews and group discussions showed that family planning services are easy to access for Rwandans—due to two types of family planning providers filling different roles to assist Rwandans start and keep using family planning methods. Family planning services are included in services for pregnant, delivering, and postpartum mothers—as well as services for infants and children. These are all times when those adults using the services would also be in need of family planning services. The family planning service delivery team approach—as well as including family planning services in mother’s and children’s health services likely helps explain the increase in family planning use in Rwanda. Other nations might learn from Rwanda’s service delivery approach to family planning to also increase access to family planning for their citizens.

Climate change affects the physiology of cocoa; however, research under high temperature and elevated [CO2] is scant. It is important to consider the physiological response of cocoa to the interaction of these environmental variables and thus generate an accurate prediction of how this crop will respond to climate change. In order to know whether elevated [CO2] leads to an increase in photosynthetic rate (A) and water use efficiency (WUE), thereby decreasing the negative impact of elevated temperature on physiology of cocoa (Theobroma cacao L), gas exchange, diurnal carbon:water balance (DCWB), photochemical activity of PSII, response curves of A to intercellular [CO2] (A/Ci curves) and growth were determined in two high temperature (T) sensitive cocoa clones (INIFAP-8 and Neocriollo) cultivated in controlled growth chambers for 100 days. The chamber environmental conditions were low [CO2]- low T (LCLT; 400 µmol CO2 mol−1 and 30 °C); high [CO2]- high T (HCHT; 1200 µmol CO2 mol−1 and 40 °C); high [CO2]- low T (HCLT; 1200 µmol CO2 mol−1 and 30 °C) and low [CO2]- high T (LCHT; 400 µmol CO2 mol−1 and 40 °C). A significant increase in A, WUE, DCWB and growth was found in both clones grown at high [CO2]. However, high T (40 °C) considerably decreased the physiology of both clones but its impact was significantly mitigated by elevated [CO2]. The results show that the physiological effects generated by elevated [CO2] could reduce the negative impact of increased temperatures, increasing the tolerance range of cocoa in the future.

Between 2005 and 2020, total contraceptive use among married women in Rwanda increased from 17% to 64%. The aim of this study is to better understand how the Rwandan government's mobilization and demand generation efforts have impacted community norms and interpersonal discourse surrounding family planning. Eight focus group discussions with family planning providers and 32 in-depth interviews with experienced modern contraceptive users were conducted in 2018 in the two Rwandan districts with the highest and the lowest contraceptive prevalence rates. Results suggest that outspoken government support, mass media, and community meetings were valuable sources of information about family planning. Information received through these channels generated interpersonal dialogue about contraceptives through both conversation and observation; however, rumors and misinformation remained a significant barrier to use. A once taboo subject is now normative among married couples. Continuing to address common fears and misinformation through communication channels such as mass media and community meetings may help to further increase contraceptive uptake in Rwanda.
