Effects of cultivar and harvest days after planting on dry matter yield and nutritive value of teff

Abstract One of the most pressing issues facing the dairy industry is drought. In areas where annual precipitation is low, irrigation for growing feed presents the greatest water-utilization challenge for dairy producers. Here, we investigated the effects of cultivar and harvest days after planting (DAP) on dry matter (DM) yield and nutritive value of teff (Eragrostis tef), a warm-season annual grass native to Ethiopia that is well adapted to drought conditions. Eighty pots were blocked by location in a greenhouse and randomly assigned to four teff cultivars (Tiffany, Moxie, Corvallis, and Dessie) and to five harvest times (40, 45, 50, 55, or 60 DAP). Cultivars had no effect on DM yield and nutritive value. As harvest time increased from 40 to 60 DAP, DM yield and ash-free neutral detergent fiber (aNDFom) concentrations increased, while crude protein (CP) concentrations and in vitro NDF digestibility decreased. To assess carryover effects of time of harvest on yield and nutritive value, two additional cuttings were taken from each pot. Increasing first-cutting harvest time decreased CP concentrations in the second cutting and reduced DM yields in the second and third cutting. Harvesting teff between 45 and 50 DAP best optimized forage yield and nutritive value in the first and subsequent cuttings.
Attitudes toward a mindfulness-based intervention from African American women living with HIV: A qualitative study

Introduction: Mindfulness-based interventions train participants to pay attention to their own emotions in the current moment without judging themselves. This study aims to assess the attitudes toward a mindfulness-based stress reduction intervention among African American women living with HIV. Methods: We collected qualitative data from three focus group discussions with 18 African American women living with HIV who were purposely recruited from the Palmetto Health-USC Immunology Center in South Carolina, United States. The participants discussed how they coped with stress, and then were given a presentation on mindfulness-based stress reduction and a sample mindfulness-based stress reduction mini workshop with follow-up discussion about their thoughts and opinions on the information presented to them. Results: Participants said that mindfulness could be a useful technique and they were interested in participating in a mindfulness-based stress reduction program. Their main concerns included physical ability to perform some of the mindfulness techniques (e.g. yoga) and logistic barriers, such as schedule constraints. They also provided some suggestions to further tailor the mindfulness-based stress reduction, such as modifying yoga, using familiar terms, and combining both in-person and online components. These results suggest that African American women living with HIV showed strong interest in mindfulness-based stress reduction and a high level of willingness to participate in mindfulness-based stress reduction, but the existing mindfulness-based stress reduction program needs to be tailored to address challenges and barriers these women may face for attendance and completion. Conclusion: The next step is to further test the feasibility, acceptability, and efficacy through a pilot study for African American women living with HIV to practice a tailored mindfulness-based stress reduction for this group.
Arrdc4‐dependent extracellular vesicle biogenesis is required for sperm maturation

Abstract Extracellular vesicles (EVs) are important players in cell to cell communication in reproductive systems. Notably, EVs have been found and characterized in the male reproductive tract, however, direct functional evidence for their importance in mediating sperm function is lacking. We have previously demonstrated that Arrdc4, a member of the α‐arrestin protein family, is involved in extracellular vesicle biogenesis and release. Here we show that Arrdc4‐mediated extracellular vesicle biogenesis is required for proper sperm function. Sperm from Arrdc4–/– mice develop normally through the testis but fail to acquire adequate motility and fertilization capabilities through the epididymis, as observed by reduced motility, premature acrosome reaction, reduction in zona pellucida binding and two‐cell embryo production. We found a significant reduction in extracellular vesicle production by Arrdc4–/‐ epididymal epithelial cells, and further, supplementation of Arrdc4–/– sperm with additional vesicles dampened the acrosome reaction defect and restored zona pellucida binding. These results indicate that Arrdc4 is important for proper sperm maturation through the control of extracellular vesicle biogenesis.
Modeling vegetation greenness and its climate sensitivity with deep‐learning technology

Abstract Climate sensitivity of vegetation has long been explored using statistical or process‐based models. However, great uncertainties still remain due to the methodologies’ deficiency in capturing the complex interactions between climate and vegetation. Here, we developed global gridded climate–vegetation models based on long short‐term memory (LSTM) network, which is a powerful deep‐learning algorithm for long‐time series modeling, to achieve accurate vegetation monitoring and investigate the complex relationship between climate and vegetation. We selected the normalized difference vegetation index (NDVI) that represents vegetation greenness as model outputs. The climate data (monthly temperature and precipitation) were used as inputs. We trained the networks with data from 1982 to 2003, and the data from 2004 to 2015 were used to validate the models. Error analysis and sensitivity analysis were performed to assess the model errors and investigate the sensitivity of global vegetation to climate change. Results show that models based on deep learning are very effective in simulating and predicting the vegetation greenness dynamics. For models training, the root mean square error (RMSE) is <0.01. Model validation also assure the accuracy of our models. Furthermore, sensitivity analysis of models revealed a spatial pattern of global vegetation to climate, which provides us a new way to investigate the climate sensitivity of vegetation. Our study suggests that it is a good way to integrate deep‐learning method to monitor the vegetation change under global change. In the future, we can explore more complex climatic and ecological systems with deep learning and coupling with certain physical process to better understand the nature.
Nocturnal incubation recess and flushing behavior by duck hens

Abstract Incubating birds must balance the needs of their developing embryos with their own physiological needs, and many birds accomplish this by taking periodic breaks from incubation. Mallard (Anas platyrhynchos) and gadwall (Mareca strepera) hens typically take incubation recesses in the early morning and late afternoon, but recesses can also take place at night. We examined nocturnal incubation recess behavior for mallard and gadwall hens nesting in Suisun Marsh, California, USA, using iButton temperature dataloggers and continuous video monitoring at nests. Fourteen percent of all detected incubation recesses (N = 13,708) were nocturnal and took place on 20% of nest‐days (N = 8,668). Video monitoring showed that hens covered their eggs with down feathers when they initiated a nocturnal recess themselves as they would a diurnal recess, but they left the eggs uncovered in 94% of the nocturnal recesses in which predators appeared at nests. Thus, determining whether or not eggs were left uncovered during a recess can provide strong indication whether the recess was initiated by the hen (eggs covered) or a predator (eggs uncovered). Because nest temperature decreased more rapidly when eggs were left uncovered versus covered, we were able to characterize eggs during nocturnal incubation recesses as covered or uncovered using nest temperature data. Overall, we predicted that 75% of nocturnal recesses were hen‐initiated recesses (eggs covered) whereas 25% of nocturnal recesses were predator‐initiated recesses (eggs uncovered). Of the predator‐initiated nocturnal recesses, 56% were accompanied by evidence of depredation at the nest during the subsequent nest monitoring visit. Hen‐initiated nocturnal recesses began later in the night (closer to morning) and were shorter than predator‐initiated nocturnal recesses. Our results indicate that nocturnal incubation recesses occur regularly (14% of all recesses) and, similar to diurnal recesses, most nocturnal recesses (75%) are initiated by the hen rather than an approaching predator.
Woodpeckers can act as dispersal vectors for fungi, plants, and microorganisms

Abstract Bird‐mediated dispersal is presumed to be important in the dissemination of many different types of organisms, but concrete evidence remains scarce. This is especially true for biota producing microscopic propagules. Tree‐dwelling birds, such as woodpeckers, would seem to represent ideal dispersal vectors for organisms growing on standing tree trunks such as epiphytic lichens and fungi. Here, we utilize bird natural history collections as a novel source of data for studying dispersal ecology of plants, fungi, and microorganisms. We screened freshly preserved specimens of three Finnish woodpecker species for microscopic propagules. Samples were taken from bird feet, and chest and tail feathers. Propagules were extracted using a sonication–centrifugation protocol, and the material obtained was studied using light microscopy. Diverse biological material was recovered from all specimens of all bird species, from all positions sampled. Most abundant categories of discovered biological material included bryophyte fragments, fungal spores, and vegetative propagules of lichens. Also, freshwater diatoms, bryophyte spores, algal cells, testate amebae, rotifers, nematodes, pollen, and insect scales were identified. The method developed here is applicable to living specimens as well, making it a versatile tool for further research. Our findings highlight the potential of bird‐mediated dispersal for diverse organisms and showcase the use of natural history collections in ecological research.
Developing Individual Performance Working at Planning Extension Programs in the Context of Decentralization in Baghdad Governance

This study aimed to evaluate the individual performance in the field of planning extension programs in the context of decentralization in the Baghdad governorate, and to set suggestions to develop the performance of those workers. A descriptive approach was adopted in the setting of the theoretical framework of the research. The study population consisted of the agricultural centers in Iraq. The researcher followed the intentional sample method, whereby the agricultural centers in the capital, Baghdad, were chosen. Regarding the sampling units, they were chosen according to comprehensive inventory method so that they included all workers (managers executives) in the agricultural centers in Baghdad with a total number of 150. The questionnaires were distributed overall the sample items personally by the researcher, and then returned to the researcher in the same way. The results of the descriptive analysis showed that the skill development variable related to the educational tasks has a mean of 4.14 and a standard deviation of 0.525. The skill development variable related to the management of extension programs has a mean of 4.12, and a standard deviation of 0.595. For a skill development related to executive tasks, it took a mean of 4.065 and 0.452 standard deviation, which corresponds to “strongly agree” of the adopted scale. The values of the relative importance of the studied dimensions confirmed the proper ranking, as the relative importance of skill development related to executive tasks was 80.4%, followed by skill development related to educational tasks (73.55%), and finally skill development related to extension programs management (73.53%)
Effects of a Multicomponent Exercise Program on Groups of Community-Dwelling Older Adults with Low Schooling: A Pilot Study

The aim of this study was to analyze the effects of a multicomponent exercise program on the physical and hemodynamic functions of community-dwelling older adults with low schooling levels in relation to simple multicomponent group exercises. Twenty-one older people were randomly assigned to two groups: G1 (n = 11) and G2 (n = 10); sixteen of whom completed the sixteen sessions over a six-week period, three times a week. During eight sessions, G1 performed adapted dual-task multicomponent exercises (strengthening, balance, and cognition) and G2 simple multicomponent exercises (strengthening and balance), and both groups engaged in eight additional sessions of simple multicomponent exercises. The dual-task multicomponent exercises exhibited similar effects to those of their simple multicomponent counterparts. The older adults from both groups improved mobility, frailty, static postural control, balance, and hemodynamic stability. The adapted program was beneficial to the community-dwelling older people with low schooling in the group intervention.
Exploring online social networks of school leaders in times of COVID‐19

Abstract The COVID‐19 pandemic has raised a wide range of challenges for school leaders that they now (rapidly) have to address. Consequently, they also turn to informal learning networks, in order to share and collect information and reach out to their communities. In this context, the current study investigates the underlying networks structures among school leaders, what type of information is being shared, and what differences can be identified when comparing a nation‐wide and a localized sample. We collected data from a US nation‐wide sample of 15 relevant Twitter conversations, as well as Tweets from an US urban mid‐sized public school district. Using a mixed‐methods approach, we discovered several key structural dimensions and a host of highly influential actors. Moreover, we found semantic evidence for users sharing information on topics such as status reports. Finally, we discovered that the urban sample did not overly use the nation‐wide, very specific approach of including COVID‐19 related hashtags. Instead, they used more localized terminologies. These findings are valuable for policy makers, as they map the underlying communication patterns and provide valuable insights into who is moving what types of resources as part of the emerging governance approach on social media. Practitioner notes What is already known about this topic Informal networks can be instrumental in providing support during challenging circumstances. School leaders hold a critical position in these networks by accessing and sharing just‐in‐time information and knowledge. Social media provide a wide range of affordances that can support the development of informal networks. What this paper adds Insights into the intersection between leadership and social networks. Information on how school leaders turn to informal networks on social media to access and share information that can help them to face the challenges caused by the global COVID‐19 pandemic. Results on underlying informal learning network structures and topical discussions of a US nation‐wide data sample. Implications for practice and/or policy Insights are provided on how informal online networks develop, which can be instrumental when considering other networks that are of interest to practitioners and policy makers. Types of information and resources that are being shared are unraveled, which can act as an indicator of what type of information and resources school leaders are looking for, particularly in the face of a crisis like the global COVID‐19 pandemic. Differences are shown in how informal learning networks are used comparing a nation‐wide exchange with a localized, urban discussion, which can help to better target the applicable audiences.
Lose Pain, Lose Weight, and Lose Both: A Cohort Study of Patients with Chronic Pain and Obesity Using a National Quality Registry

Background It is known that chronic pain makes it difficult to lose weight, but it is unknown whether obese patients (body mass index ≥30 kg/m2) who experience significant pain relief after interdisciplinary multimodal pain rehabilitation (IMMPR) lose weight. Objective This study investigated whether obese patients with chronic pain lost weight after completing IMMPR in specialist pain units. The association of pain relief and weight change over time was also examined. Methods Data from obese patients included in the Swedish Quality Registry for Pain Rehabilitation for specialized pain units were used (N=224), including baseline and 12-month follow-up after IMMPR from 2016 to 2018. Patients reported body weight and height, pain aspects (eg, pain intensity), physical activity behaviours, psychological distress, and health-related quality of life (HRQoL). A reduction of at least 5% of initial weight indicates clinically significant weight loss. Patients were classified into three groups based on the pain relief levels after IMMPR: pain relief of clinical significance (30% or more reduction of pain intensity); pain relief without clinical significance (less than 30% reduction of pain intensity); and no pain relief. Linear mixed regression models were used to examine the weight changes among the groups with different pain relief levels. Results A significant reduction of pain intensity was found after IMMPR (p < 0.01, effect size Cohen’s d = 0.34). A similar proportion of patients in the three groups with different pain relief levels had clinically significant weight loss (20.2%~24.3%, p = 0.47). Significant improvements were reported regarding physical activity behaviour, psychological distress, and HRQoL, but weight change was not associated with changes of pain intensity. Conclusion About one-fifth of obese patients achieved significant weight reduction after IMMPR. Obese patients need a tailored pain rehabilitation program incorporating a targeted approach for weight management.
Association of Oxidative Balance Score with the Metabolic Syndrome in a Sample of Iranian Adults

Objective We aimed to assess the association of the oxidative balance score (OBS) with metabolic syndrome (MetS) in adults. Design A population-based cross-sectional study Setting. Health centers from five districts in Tehran, Iran. Methods We recruited 847 participants with an age range of 18-65 years. Dietary intake was assessed by a semiquantitative food frequency questionnaire with 168 items. The OBS was calculated by using the following 13 dietary and nondietary anti- and prooxidant components: dietary antioxidants (selenium, fiber, β-carotene, vitamin D, vitamin C, vitamin E, and folate), dietary prooxidants (iron and saturated and polyunsaturated fatty acids), and nondietary anti- (physical activity) and prooxidants (smoking and obesity). The odds ratio (OR) and 95% confidence interval (CI) of the MetS and its components across tertiles of the OBS were calculated by logistic regression analysis, controlling for age, sex, energy intake, occupation, and educational level. Results The range of OBS was between 16 and 39. Being in the top versus the bottom tertile of the OBS was not associated with the MetS (OR = 0.71, 95% CI 0.48-1.03; P = 0.07), after controlling for potential confounders. Higher OBS score was associated with a lower likelihood of abdominal obesity (OR: 0.55, 95% CI: 0.38-0.81; P = 0.003) and increased diastolic blood pressure (OR: 0.64, 95% CI: 0.41-0.99; P = 0.04). Higher OBS was not associated with other components of the MetS. Conclusion Overall, the present study showed that there was no significant relationship between OBS and MetS in Tehranian adults.
Association Between Cemented vs Cementless Hemiarthroplasty and Short-Term Change of In-Hospital Mortality in Elderly Patients with Femoral Neck Fracture: A Propensity-Score Matching Analysis in a Multicenter Database

Objective Cemented hemiarthroplasty is recommended for the vulnerable hip fracture population because of beneficial long-term outcomes. However, the association between cemented hemiarthroplasty and short-term mortality is controversial. To increase a preparedness of potential complication after cemented hemiarthroplasty, we aimed to evaluate the trajectory of the effect of cemented hemiarthroplasty on short-term in-hospital outcomes. Methods We investigated in-hospital mortality and complications between cemented hemiarthroplasty and cementless hemiarthroplasty using a nationwide multicenter database from 2010 to 2016 with a propensity-score matching analysis. We analyzed in-hospital mortality from 1 to 14 days after surgery. We also investigated in-hospital complications that may associate with mortality. Results After matching of 31,322 cases, we found no significant difference in 30-day in-hospital mortality between the cemented and cementless hemiarthroplasty groups (hazard ratio, HR [95% confidence interval, CI], 1.2 [0.89–1.6], p = 0.23). However, the 1- to 10-day postoperative mortality rates were significantly higher in the cemented group and the association becomes weaker as the postoperative period increased (day 1; HR [95% CI]: 3.5 [1.6–7.68]; day 10; HR [95% CI]: 1.59 [1.07–2.37]). The incidence of stroke and intensive care unit (ICU) admission was also significantly higher in the cemented group. Conclusion Cemented hemiarthroplasty was not significantly associated with an increase in overall in-hospital mortality but was significantly associated with short-term mortality from 1-day to 10-day after surgery. The incidence of stroke and ICU admission was also significantly higher in the cemented group. Surgeons should pay more attention to the risk of mortality and stroke in patients undergoing cemented hemiarthroplasty, especially in the early days of hospitalization.
Manoli, Aikaterini (2018) “Waving your thoughts goodbye”: A two-minute and instant mindfulness approach for decreasing female body dissatisfac-

Body dissatisfaction is prevalent in females, leading to detrimental physical and psychological outcomes. Mindfulness might successfully reduce body dissatisfaction through decentering, the metacognitive aspect of viewing thoughts as transient mental events. Most previous research has examined the effects of extended acceptance-based mindfulness interventions on body dissatisfaction, with very few studies considering the effectiveness of brief decentering approaches. This study examined whether radically short (two-minute or “instant”) mindfulness interventions could decrease body dissatisfaction compared to a control condition in 102 females (18-30 years), after exposure to “ideally thin” body dissatisfaction trigger-stimuli. It was hypothesised that both two-minute and instant approaches would decrease body dissatisfaction, while being equally effective. Results supported the prediction that both interventions would decrease body dissatisfaction. Additionally, Bayesian analysis provided anecdotal evidence that both interventions were equally effective. In addition to demonstrating that brief decentering interventions can protect from body dissatisfaction, the study is the first to support the feasibility of an instant mindfulness approach, opening the way for future research.
