Title: Farm production, market access and dietary diversity in Malawi
Abstract: Abstract Objective The association between farm production diversity and dietary diversity in rural smallholder households was recently analysed. Most existing studies build on household-level dietary diversity indicators calculated from 7d food consumption recalls. Herein, this association is revisited with individual-level 24 h recall data. The robustness of the results is tested by comparing household- and individual-level estimates. The role of other factors that may influence dietary diversity, such as market access and agricultural technology, is also analysed. Design A survey of smallholder farm households was carried out in Malawi in 2014. Dietary diversity scores are calculated from 24 h recall data. Production diversity scores are calculated from farm production data covering a period of 12 months. Individual- and household-level regression models are developed and estimated. Setting Data were collected in sixteen districts of central and southern Malawi. Subjects Smallholder farm households (n 408), young children (n 519) and mothers (n 408). Results Farm production diversity is positively associated with dietary diversity. However, the estimated effects are small. Access to markets for buying food and selling farm produce and use of chemical fertilizers are shown to be more important for dietary diversity than diverse farm production. Results with household- and individual-level dietary data are very similar. Conclusions Further increasing production diversity may not be the most effective strategy to improve diets in smallholder farm households. Improving access to markets, productivity-enhancing inputs and technologies seems to be more promising.

Title: Agroecological practices of legume residue management and crop diversification for improved smallholder food security, dietary diversity and sustainable land use in Malawi
Abstract: ABSTRACT The role of agroecological practices in addressing food security has had limited investigation, particularly in Sub-Saharan Africa. Quasi-experimental methods were used to assess the role of agroecological practices in reducing food insecurity in smallholder households in Malawi. Two key practices – crop diversification and the incorporation of organic matter into soil – were examined. The quasi-experimental study of an agroecological intervention included survey data from 303 households and in-depth interviews with 33 households. The survey sampled 210 intervention households participating in the agroecological intervention, and 93 control households in neighboring villages. Regression analysis of food security indicators found that both agroecological practices significantly predicted higher food security and dietary diversity for smallholder households: the one-third of farming households who incorporated legume residue soon after harvest were almost three times more likely to be food secure than those who had not incorporated crop residue. Qualitative semi-structured interviews with 33 households identified several pathways through which crop diversification and crop residue incorporation contributed to household food security: direct consumption, agricultural income, and changes in underlying production relations. These findings provide evidence of agroecology’s potential to address food insecurity while supporting sustainable food systems.

Title: If They Grow It, Will They Eat and Grow? Evidence from Zambia on Agricultural Diversity and Child Undernutrition
Abstract: Abstract In this article we address a gap in our understanding of how household agricultural production diversity affects the diets and nutrition of young children living in rural farming communities in sub-Saharan Africa. The specific objectives of this article are to assess: (1) the association between household agricultural production diversity and child dietary diversity; and (2) the association between household agricultural production diversity and child nutritional status. We use household survey data collected from 3,040 households as part of the Realigning Agriculture for Improved Nutrition (RAIN) intervention in Zambia. The data indicate low agricultural diversity, low dietary diversity and high levels of chronic malnutrition overall in this area. We find a strong positive association between production diversity and dietary diversity among younger children aged 6–23 months, and significant positive associations between production diversity and height for age Z-scores and stunting among older children aged 24–59 months.

Title: Nutrition education, farm production diversity, and commercialization on household and individual dietary diversity in Zimbabwe
Abstract: Background Nutrition education is crucial for improved nutrition outcomes. However, there are no studies to the best of our knowledge that have jointly analysed the roles of nutrition education, farm production diversity and commercialization on household, women and child dietary diversity. Objective This article jointly analyses the role of nutrition education, farm production diversity and commercialization on household, women and children dietary diversity in Zimbabwe. In addition, we analyze separately the roles of crop and livestock diversity and individual agricultural practices on dietary diversity. Design Data were collected from 2,815 households randomly selected in eight districts. Negative binomial regression was used for model estimations. Results Nutrition education increased household, women, and child dietary diversity by 3, 9 and 24%, respectively. Farm production diversity had a strong and positive association with household and women dietary diversity. Crop diversification led to a 4 and 5% increase in household and women dietary diversity, respectively. Furthermore, livestock diversification and market participation were positively associated with household, women, and children dietary diversity. The cultivation of pulses and fruits increased household, women, and children dietary diversity. Vegetable production and goat rearing increased household and women dietary diversity. Conclusions Nutrition education and improving access to markets are promising strategies to improve dietary diversity at both household and individual level. Results demonstrate the value of promoting nutrition education; farm production diversity; small livestock; pulses, vegetables and fruits; crop-livestock integration; and market access for improved nutrition.

Title: Individual differences and changes in subjective wellbeing during the early stages of the COVID-19 pandemic.
Abstract: The COVID-19 pandemic has considerably impacted many people's lives. This study examined changes in subjective wellbeing between December 2019 and May 2020 and how stress appraisals and coping strategies relate to individual differences and changes in subjective wellbeing during the early stages of the pandemic. Data were collected at 4 time points from 979 individuals in Germany. Results showed that, on average, life satisfaction, positive affect, and negative affect did not change significantly between December 2019 and March 2020 but decreased between March and May 2020. Across the latter timespan, individual differences in life satisfaction were positively related to controllability appraisals, active coping, and positive reframing, and negatively related to threat and centrality appraisals and planning. Positive affect was positively related to challenge and controllable-by-self appraisals, active coping, using emotional support, and religion, and negatively related to threat appraisal and humor. Negative affect was positively related to threat and centrality appraisals, denial, substance use, and self-blame, and negatively related to controllability appraisals and emotional support. Contrary to expectations, the effects of stress appraisals and coping strategies on changes in subjective wellbeing were small and mostly nonsignificant. These findings imply that the COVID-19 pandemic represents not only a major medical and economic crisis, but also has a psychological dimension, as it can be associated with declines in key facets of people's subjective wellbeing. Psychological practitioners should address potential declines in subjective wellbeing with their clients and attempt to enhance clients' general capability to use functional stress appraisals and effective coping strategies.

Title: Who is most affected by the Corona crisis? An analysis of changes in stress and well-being in Switzerland
Abstract: ABSTRACT This study analyses the consequences of the Covid-19 crisis on stress and well-being in Switzerland. In particular, we assess whether vulnerable groups in terms of social isolation, increased workload and limited socioeconomic resources are affected more than others. Using longitudinal data from the Swiss Household Panel, including a specific Covid-19 study, we estimate change score models to predict changes in perceived stress and life satisfaction at the end of the semi-lockdown in comparison to before the crisis. We find no general change in life satisfaction and a small decrease in stress. Yet, in line with our expectations, more vulnerable groups in terms of social isolation (young adults, Covid-19 risk group members, individuals without a partner), workload (women) and socioeconomic resources (unemployed and those who experienced a deteriorating financial situation) reported a decrease in life satisfaction. Stress levels decreased most strongly among high earners, workers on short-time work and the highly educated.

Title: Malay Named Entity Recognition Based on Rule-Based Approach
Abstract: A Named-Entity Recognition (NER) is part of the process in Text Mining and it is a very useful process for information extraction. This NER tool can be used to assist user in identifying and detecting entities such as person, location or organization. However, different languages may have different morphologies and thus require different NER processes. For instance, an English NER process cannot be applied in processing Malay articles due to the different morphology used in different languages. This paper proposes a Rule-Based Named-Entity Recognition algorithm for Malay articles. The proposed Malay NER is designed based on a Malay part-of-speech (POS) tagging features and contextual features that had been implemented to handle Malay articles. Based on the POS results, proper names will be identified or detected as the possible candidates for annotation. Besides that, there are some symbols and conjunctions that will also be considered in the process of identifying named-entity for Malay articles. Several manually constructed dictionaries will be used to handle three named-entities; Person, Location and Organizations. The experimental results show a reasonable output of 89.47% for the F-Measure value. The proposed Malay NER algorithm can be further improved by having more complete dictionaries and refined rules to be used in order to identify the correct Malay entities system.

Title: Hackathons as Co-optation Ritual: Socializing Workers and Institutionalizing Innovation in the “New” Economy
Abstract: Abstract Hackathons, time-bounded events where participants write computer code and build apps, have become a popular means of socializing tech students and workers to produce “innovation” despite little promise of material reward. Although they offer participants opportunities for learning new skills and face-to-face networking and set up interaction rituals that create an emotional “high,” potential advantage is even greater for the events’ corporate sponsors, who use them to outsource work, crowdsource innovation, and enhance their reputation. Ethnographic observations and informal interviews at seven hackathons held in New York during the course of a single school year show how the format of the event and sponsors’ discursive tropes, within a dominant cultural frame reflecting the appeal of Silicon Valley, reshape unpaid and precarious work as an extraordinary opportunity, a ritual of ecstatic labor, and a collective imaginary for fictional expectations of innovation that benefits all, a powerful strategy for manufacturing workers’ consent in the “new” economy.

Title: Estimative of real number of infections by COVID-19 in Brazil and possible scenarios
Abstract: Abstract This paper attempts to provide methods to estimate the real scenario of the novel coronavirus pandemic crisis on Brazil and the states of Sao Paulo, Pernambuco, Espirito Santo, Amazonas and Distrito Federal. By the use of a SEIRD mathematical model with age division, we predict the infection and death curve, stating the peak date for Brazil and these states. We also carry out a prediction for the ICU demand on these states for a visualization of the size of a possible collapse on the local health system. By the end, we establish some future scenarios including the stopping of social isolation and the introduction of vaccines and efficient medicine against the virus.

Title: Short-Term Traffic Prediction Based on DeepCluster in Large-Scale Road Networks
Abstract: Short-term traffic prediction (STTP) is one of the most critical capabilities in Intelligent Transportation Systems (ITS), which can be used to support driving decisions, alleviate traffic congestion and improve transportation efficiency. However, STTP of large-scale road networks remains challenging due to the difficulties of effectively modeling the diverse traffic patterns by high-dimensional time series. Therefore, this paper proposes a framework that involves a deep clustering method for STTP in large-scale road networks. The deep clustering method is employed to supervise the representation learning in a visualized way from the large unlabeled dataset. More specifically, to fully exploit the traffic periodicity, the raw series is first divided into a number of sub-series for triplet generation. The convolutional neural networks (CNNs) with triplet loss are utilized to extract the features of shape by transforming the series into visual images. The shape-based representations are then used to cluster road segments into groups. Thereafter, a model sharing strategy is further proposed to build recurrent NNs-based predictions through group-based models (GBMs). GBM is built for a type of traffic patterns, instead of one road segment exclusively or all road segments uniformly. Our framework can not only significantly reduce the number of prediction models, but also improve their generalization by virtue of being trained on more diverse examples. Furthermore, the proposed framework over a selected road network in Beijing is evaluated. Experiment results show that the deep clustering method can effectively cluster the road segments and GBM can achieve comparable prediction accuracy against the IBM with less number of prediction models.

Title: Prevalence and Incidence of Epilepsy in Italy Based on a Nationwide Database
Abstract: Objectives: To estimate the prevalence and incidence of epilepsy in Italy using a national database of general practitioners (GPs). Methods: The Health Search CSD Longitudinal Patient Database (HSD) has been established in 1998 by the Italian College of GPs. Participants were 700 GPs, representing a population of 912,458. For each patient, information on age and sex, EEG, CT scan, and MRI was included. Prevalent cases with a diagnosis of ‘epilepsy' (ICD9CM: 345*) were selected in the 2011 population. Incident cases of epilepsy were identified in 2011 by excluding patients diagnosed for epilepsy and convulsions and those with EEG, CT scan, MRI prescribed for epilepsy and/or convulsions in the previous years. Crude and standardized (Italian population) prevalence and incidence were calculated. Results: Crude prevalence of epilepsy was 7.9 per 1,000 (men 8.1; women 7.7). The highest prevalence was in patients <25 years and ≥75 years. The incidence of epilepsy was 33.5 per 100,000 (women 35.3; men 31.5). The highest incidence was in women <25 years and in men 75 years or older. Conclusions: Prevalence and incidence of epilepsy in this study were similar to those of other industrialized countries. HSD appears as a reliable data source for the surveillance of epilepsy in Italy. i 2014 S. Karger AG, Basel

Title: Association between dietary patterns and overweight risk among Malaysian adults: evidence from nationally representative surveys
Abstract: Abstract Objective: To investigate the association between dietary patterns (DP) and overweight risk in the Malaysian Adult Nutrition Surveys (MANS) of 2003 and 2014. Design: DP were derived from the MANS FFQ using principal component analysis. The cross-sectional association of the derived DP with prevalence of overweight was analysed. Setting: Malaysia. Participants: Nationally representative sample of Malaysian adults from MANS (2003, n 6928; 2014, n 3000). Results: Three major DP were identified for both years. These were ‘Traditional’ (fish, eggs, local cakes), ‘Western’ (fast foods, meat, carbonated beverages) and ‘Mixed’ (ready-to-eat cereals, bread, vegetables). A fourth DP was generated in 2003, ‘Flatbread & Beverages’ (flatbread, creamer, malted beverages), and 2014, ‘Noodles & Meat’ (noodles, meat, eggs). These DP accounted for 25·6 and 26·6 % of DP variations in 2003 and 2014, respectively. For both years, Traditional DP was significantly associated with rural households, lower income, men and Malay ethnicity, while Western DP was associated with younger age and higher income. Mixed DP was positively associated with women and higher income. None of the DP showed positive association with overweight risk, except for reduced adjusted odds of overweight with adherence to Traditional DP in 2003. Conclusions: Overweight could not be attributed to adherence to a single dietary pattern among Malaysian adults. This may be due to the constantly morphing dietary landscape in Malaysia, especially in urban areas, given the ease of availability and relative affordability of multi-ethnic and international foods. Timely surveys are recommended to monitor implications of these changes.

Title: Dinitrogen fixation rates in the Bay of Bengal during summer monsoon
Abstract: Abstract Biological dinitrogen (N 2 ) fixation exerts an important control on oceanic primary production by providing bioavailable form of nitrogen (such as ammonium) to photosynthetic microorganisms. N 2 fixation is dominant in nutrient poor and warm surface waters. The Bay of Bengal is one such region where no measurements of phototrophic N 2 fixation rates exist. The surface water of the Bay of Bengal is generally nitrate-poor and warm due to prevailing stratification and thus, could favour N 2 fixation. We commenced the first N 2 fixation study in the photic zone of the Bay of Bengal using 15 N 2 gas tracer incubation experiment during summer monsoon 2018. We collected seawater samples from four depths (covering the mixed layer depth of up to 75 m) at eight stations. N 2 fixation rates varied from 4 to 75 μ mol N m −2 d −1 . The contribution of N 2 fixation to primary production was negligible (&lt;1%). However, the upper bound of observed N 2 fixation rates is higher than the rates measured in other oceanic regimes, such as the Eastern Tropical South Pacific, the Tropical Northwest Atlantic, and the Equatorial and Southern Indian Ocean.

Title: Far infrared and Raman spectroscopic investigations of lunar materials from Apollo 11, 12, 14, and 15
Abstract: We have studied the elastic and inelastic light scattering of twelve lunar surface rocks and eleven lunar soil samples from Apollo 11, 12, 14, and 15, over the range 20-2000 em-I. The phonons occurring in this frequency region have been associated with the different chemical constituents and are used to determine the mineralogical abundances by comparison with the spectra of a wide variety of terrestrial minerals and rocks. KramersKronig analyses of the infrared reflectance spectra provided the dielectric dispersion (e' and s") and the optical constants (n and k). The dielectric constants at "" 1011 Hz have been obtained for each sample and are compared with the values reported in the 10-10 Hz range. The emissivity peak at the Christianson frequencies for all the lunar samples lie within the range 1195-1250 cm-1; such values are characteristic of terrestrial basalts. The Raman light scattering spectra provided investigation of small individual grains or inclusions and gave unambiguous interpretation of some of the characteristic mineralogical components.

Title: Anastomosis Groups and Pathogenicity of Rhizoctonia solani and Binucleate Rhizoctonia from Potato in South Africa
Abstract: A survey of anastomosis groups (AG) of Rhizoctonia spp. associated with potato diseases was conducted in South Africa. In total, 112 Rhizoctonia solani and 19 binucleate Rhizoctonia (BNR) isolates were recovered from diseased potato plants, characterized for AG and pathogenicity. The AG identity of the isolates was confirmed using phylogenetic analysis of the internal transcribed spacer region of ribosomal DNA. R. solani isolates recovered belonged to AG 3-PT, AG 2-2IIIB, AG 4HG-I, AG 4HG-III, and AG 5, while BNR isolates belonged to AG A and AG R, with frequencies of 74, 6.1, 2.3, 2.3, 0.8, 12.2, and 2.3%, respectively. R. solani AG 3-PT was the most predominant AG and occurred in all the potato-growing regions sampled, whereas the other AG occurred in distinct locations. Different AG grouped into distinct clades, with high maximum parsimony and maximum-likelihood bootstrap support for both R. solani and BNR. An experiment under greenhouse conditions with representative isolates from different AG showed differences in aggressiveness between and within AG. Isolates of AG 2-2IIIB, AG 4HG-III, and AG R were the most aggressive in causing stem canker while AG 3-PT, AG 5, and AG R caused black scurf. This is the first comprehensive survey of R. solani and BNR on potato in South Africa using a molecular-based approach. This is the first report of R. solani AG 2-2IIIB and AG 4 HG-I causing stem and stolon canker and BNR AG A and AG R causing stem canker and black scurf on potato in South Africa.
