description: The study attempts to identify the costs, returns, profitability, employment and income generated through the private poultry farming in Kishoreganj district. In total 150 broiler farms were randomly selected from Kishoreganj Sadar Upazila and Katiadi Upazila. The field level data were collected during November 2004 to January 2005 through direct interviews with broiler farmers. The study shown that the gross return per farm per year was Tk. 7,85,600, per batch per farm was Tk. 1,17,079 and per bird per batch was Tk. 76.12. Costs of feed, day-old-chicks, human labour and veterinary charges were the key inputs affecting the profitability of broiler farms. The summation of elasticity of different inputs for broiler farms was less than one, implying that the production function exhibited a decreasing returns to scale i.e., doubling the inputs would less than double the output. Most of the family labour came from female especially small farms (38 per cent) which mean that the private poultry farming creates the job opportunities for the farm families. It is also observed that the small, medium, large and all broiler farms could save annually a good portion of their income earned from the poultry farming venture.

description: Background: The public health impact of digital behaviour change interventions is dependent upon sufficient real-world uptake and engagement. Purpose: To synthesise influences on the uptake and engagement with health apps, to inform new approaches that promote effective use. Methods: Studies of all designs involving adults were included if they focused on health apps reporting on uptake and engagement behaviour. Relevant electronic libraries were searched, with a proportion of studies screened independently by two authors. Data synthesis and interpretation were undertaken using a deductive iterative process. A narrative synthesis of the findings was structured around the components of the COM-B model and the Theoretical Domains Framework. Results: Out of 7640 identified studies, 41 were included in the review. Under ‘Capability’, the main factors identified were app literacy skills, user knowledge, app awareness, user guidance, health information, statistical information, well-designed reminders, features to reduce cognitive load, and self-monitoring features. Availability at low cost, positive tone and personalisation were identified as physical ‘Opportunity’ factors, while recommendations for health apps, embedded health professional support together with social networking possibilities were social ‘Opportunity’ factors. Finally, ‘Motivation’ factors included positive feedback, available rewards, goal setting and the perceived utility of the app. Conclusions: The twenty-six factors identified have clear implications for improving population health and targeting health inequalities. A list of recommendations was produced to guide app developers and policy makers when commissioning, developing and optimising health apps. Funding: Study funded by DS’s PhD studentship (funded by Public Health England and the University of East Anglia).

description: The study was conducted to interpret the socioeconomic characteristics of the dairy farmers, dairy farm management and income, impact of management activities on milk production and employment potential in dairy production. Three hundred households in three thanas of Mymensingh district were interviewed through a questionnaire. Thirty nine per cent dairy farmers were illiterate and this proportion was higher in rural areas. Ratio of dairy income to total income was higher for large farmers and in riverside area. About 52 per cent farms had single milch cow and there was 1.6 units of milk cow per dairy farm. Riverside area exhibits highest percentage of cows of local breed. Most of the cowshed were made by GI sheet and were in good conditioned. Most of the farmers do not maintain expected level of care to their milch cows. Women had significant participation in dairy milk production. Dairy farming activities of the rural people may be increased by increasing the number of dairy cows and through improving training facilities for the women and paid labourers for income generating purposes.

description: The present study revealed that among all the types of sources of information regarding the selection and use of pesticides, the intensity of exposure of the vegetable growers to radio was highest followed by newspaper, friends, farm publications and agricultural input dealers. The present study further showed that the public sector extension workers had very low level of contact with the respondents as far as the intensity of exposure of the information regarding the selection and use of pesticides among the respondents was concerned. The present study clearly showed us that a majority of the respondents (59.33 percent) rejected the information while nearly one-third of the respondents i.e. 33.33 percent accepted the information regarding the selection and use of pesticides.

description: In Government circles the East-West trade control program is usually described as an economic defense effort aimed at building up the strength of the free world vis-a-vis that of the bloc. Yet some maintain that this effort constitutes economic warfare. What is the distinction, if any, between these two terms? To get at the answer to this question, it is necessary to begin by stating that the term economic defense seems to have come intro use only recently in connection with what is known as the cold war, while the concept of economic warfare may be traced several centuries.

Publisher: name: The Health & Fitness Journal of Canada
Year: 2022

description: Background: While benefits of physical activity (PA) during and after pregnancy have been established, many women do not reach recommended PA levels during that time. A major barrier is limited counselling by healthcare providers (HCPs), partly caused by limited knowledge on the topic. Purpose: We used Intervention Mapping (IM), a theory-based framework, to develop the intervention “Baby steps” to improve PA promotion by HCPs in a high-income (Austria) and a low-to-middle income country (South Africa). Methods: We applied the following IM steps: 1) A needs assessment to determine barriers and enablers of PA promotion by HCPs, consisting of a scoping literature review and qualitative community needs assessments with midwives, obstetricians and community health workers to determine desired outcomes of the intervention. 2) Performance and change objectives were formulated, describing which behaviours need to change for the intervention to succeed. 3) Based on the change objectives, theory-based behaviour change techniques were selected and practical applications developed. 4) Practical applications were combined into two evidence-based interventions tailored to each country’s needs. Step 5) and 6) consist of an implementation and evaluation plan. Results: The intervention “Baby Steps” is aimed at HCPs, consisting of a two-day training with practical resources, combining didactic and interactive education. It addresses knowledge on PA as well as skills to transfer knowledge and facilitate behaviour changes. Conclusions: We used IM to develop a training for HCPs to improve PA promotion during and after pregnancy. In future, the intervention’s effect on women’s perinatal activity levels needs to be studied.

description: A Cob-Douglas stochastic frontier production function was estimated to determine the technical efficiency of Boro rice production in Bangladesh. Technical inefficiency effect model was also estimated simultaneously with stochastic frontiers to identify factors, which influence efficiency. The coefficients of fertilizer, irrigation and human labour were found to be significantly positive in the stochastic frontier function, which meant with increase of fertilizer, irrigation and human labour the production of Boro rice will be increased. The coefficient of extension contact was negative and significant in the inefficiency effect model in Phulpur upazIla. This indicates that inefficiency decreases with the increase in extension contact. The mean technical efficiency was 92 percent. There appeared 8 percent inefficiency, which means that the farmers increase their production 8 percent without changing the input.

description: We study prompt optical emission from reverse shocks in the wind-type gamma-ray bursts. The emission is evaluated in both the thick and thin shell regimes. We discuss the angular time delay effect and the post-shock evolution of the fireball ejecta, which determine the decay index of the prompt optical emission and the duration of the radio flare. We discuss distinct emission signatures of the wind environment compared with the constant interstellar medium environment. We also present two recipes for directly constraining the initial or early time Lorentz factor of the fireball using the reverse and forward shock optical afterglow data for the wind case.

description: Here we report timing measurements of the relativistic binary pulsar PSR J1141-6545 that constrain the component masses and demonstrate that the orbital period derivative \dot Pb = (-4+/-1)x10^-13 is consistent with gravitational wave emission as described by the general theory of relativity. The mass of the neutron star and its companion are 1.30+/-0.02 Mo and 0.986+/-0.020 Mo respectively, suggesting a white dwarf companion, and extending the range of systems for which general relativity provides a correct description. On evolutionary grounds, the progenitor mass of PSR J1141-6545 should be near the minimum for neutron star production. Its mass is two standard deviations below the mean of the other neutron stars, suggesting a relationship between progenitor and remnant masses.

description: Contract farming in seed production has played an instrumental role in bringing private investment into seed research and production. However, inefficiencies in the institutional mechanism hinder the seed producers from realizing the full potential benefits of seed contracts. The present study attempts to analyze the producer's preference for group contracts and its impact on the welfare of actors in the seed value chain. We propose two types of group contracts, viz, contract B (company-organizer-seed producers group (SPG)) and C (company-SPG). We carried out an economic experiment using real producers and organizers currently engaged in seed production. Producers face a choice between an existing contract and either of the proposed group contracts. The experiment consists of two treatments, i) concealed and revealed price information and ii) presence and absence of local organizer while making the choice decision. We find that preference for contract B is higher than contract C and the existing contract. Contract B shows higher price bargaining under the concealed price information compared to revealed treatment. Average group life of SPGs is 3.78 periods and more than half of the groups (53%) survived throughout the five rounds indicating a very high sustainability. Acknowledgement : We Acknowledge Dr. Jannaiah, for helping us in coordinating the experiment. We are truly glad for Vikram Patil and Prabhakaran, International Rice Research Institute for assisting and rolling out the experiment.

description: We present the first results from our CGM at Cosmic Noon with KCWI program to study gas flows in the circumgalactic medium (CGM) at $z=2-3$. Combining the power of a high-resolution VLT/UVES quasar spectrum, an HST/ACS image, and integral field spectroscopy with Keck/KCWI, we detected Lya emission from a $1.7L_{\ast}$ galaxy at $z_{\rm gal}=2.0711$ associated with a Lyman limit system with weak MgII ($W_r(2796)=0.24$ Ang) in quasar field J143040$+$014939. The galaxy is star-forming (${\rm SFR}_{\rm FUV}=37.8$ M$_{\odot}$ yr$^{-1}$) and clumpy: either an edge-on disk ($i=85^{\circ}$) or, less likely, a major merger. The background quasar probes the galaxy at an impact parameter of $D=66$ kpc along the projected galaxy minor axis ($Φ=89^{\circ}$). From photoionization modeling of the absorption system, we infer a total line-of-sight CGM metallicity of ${\rm [Si/H]}=-1.5^{+0.4}_{-0.3}$. The absorption system is roughly kinematically symmetric about $z_{\rm gal}$, with a full MgII velocity spread of $\sim210$ km s$^{-1}$. Given the galaxy-quasar orientation, CGM metallicity, and gas kinematics, we interpret this gas as an outflow that has likely swept-up additional material. By modeling the absorption as a polar outflow cone, we find the gas is decelerating with average radial velocity $V_{\rm out}=109-588$ km s$^{-1}$ for half opening angles of $θ_0=14^{\circ}-75^{\circ}$. Assuming a constant $V_{\rm out}$, it would take on average $t_{\rm out}\sim111-597$ Myr for the gas to reach 66 kpc. The outflow is energetic, with a mass outflow rate of $\dot{M}_{\rm out}<52{\pm37}$ M$_{\odot}$ yr$^{-1}$ and mass loading factor of $η<1.4{\pm1.0}$. We aim to build a sample of $\sim50$ MgII absorber--galaxy pairs at this epoch to better understand gas flows when they are most actively building galaxies.

description: Since the 2007-2008 world food crisis and accounting for the recurrent food crises which have affected West-Africa region within the last two decades; West-African countries have re-launched procurement programs and rebuilt food stocks. In Benin the procurement program was launched in 2008-2009. It is a state intervention on cereals market through the food reserve system. The food reserve policy operates two programs: a) market access program and b) food subsidy program implementing the fair-price-shop approach. The stratified random sampling technic was used and consumers households were clustered into participants and non-participants in the fair-price-shop program. Data were collected in 2014, 6 years after the start of the food reserve policy. Qualitative and quantitative methods were used and 210 respondents were surveyed. A treatment effect model was developed to accommodate the program operation rules; it accommodates simultaneous effect and variables of different types. The Multivariate Endogenous Treatment Effect model reveals that Fair-price-shop intervention approach as safety net program is effective at stabilizing maize market price, facilitating access to staple in shortage times and at selecting the periods for stocks release. Further it informs also, about the effectiveness of the program design in targeting the appropriate beneficiaries. Keywords: food reserve policy, fair-price-shop approach, Multivariate Endogenous Treatment Effect model. Acknowledgement :

description: Background: Sports clubs (SCs) offer a unique position to increase physical activity levels and offer additional health promotion opportunities. Purpose: To gather French stakeholder ideas on support SCs need to increase health promotion efforts and prioritized them. Methods: This concept mapping study included 4-steps: 1) drafting a key issue focus prompt, 2) brainstorming ideas in response to the focus prompt, 3) sorting ideas into themed piles and 4) rating ideas (1-6) based on two indicators. French sports and health stakeholders (45) were invited to respond using web-based groupwisdom™ software. Based on multi-dimensional scaling and hierarchical cluster analysis, visual cluster maps of piles and Go-Zone graphs displaying ideas rated as important and feasible were produced. Results: Participants generated 62 ideas from the focus prompt: ‘What assistance would benefit SCs to become a health-promoting setting?’. Final idea sorting formed 9 clusters: Tools for health promotion, Communication tools, Stakeholder training courses, Diagnostic and Financing, Awareness and Mobilization, Advocacy, Policies and Methods, Sharing and Networking and Communication and Dissemination. Ratings produced Go-Zones with 34 ideas above the mean for both indicators. Priority areas include increasing awareness of health promotion benefits, mobilizing actors, advocating for support and educating club actors. Conclusions: Generating and organizing stakeholder ideas gives insight into perceptions of what support is needed to develop and implement health promotion interventions in the sports club context which increases the possibility of acceptance and integration into policies. Funding: Study was funded by a grant from Santé publique France.

description: In order to further expand the flight envelope of quadrotors under actuator failures, we design a nonlinear sensor-based fault-tolerant controller to stabilize a quadrotor with failure of two opposing rotors in the high-speed flight condition (> 8m/s). The incremental nonlinear dynamic inversion (INDI) approach which excels in handling model uncertainties is adopted to compensate for the significant unknown aerodynamic effects. The internal dynamics of such an underactuated system have been analyzed, and subsequently stabilized by re-defining the control output. The proposed method can be generalized to control a quadrotor under single-rotor-failure and nominal conditions. For validation, flight tests have been carried out in a large-scale open jet wind tunnel. The position of a damaged quadrotor can be controlled in the presence of significant wind disturbances. A linear quadratic regulator (LQR) approach from the literature has been compared to demonstrate the advantages of the proposed nonlinear method in the windy and high-speed flight condition.

description: This study investigates the relationship between local economic conditions in Oregon and spell lengths of USDA’s Supplemental Nutrition Assistance Program (SNAP). Using different indicators of economic conditions and different definitions of local labor market areas, the report finds evidence that improved labor market conditions were associated with an increased probability that a SNAP recipient in Oregon ended a participation spell. When local labor markets are delineated as commuting zones—our preferred definition—our results suggest that a 10-percent increase in local employment raises the average recipient’s probability of program exit by nearly 7 percent. The report shows that—when labor market conditions are measured in a more localized way than is typically done—SNAP recipients are found to be more responsive to labor market conditions.

description: We present new observations of IRAS 04000+5052, a Galactic HII region associated with a young stellar cluster and possibly located at the Perseus arm. Contrary to previous claims, we have found that this object is not a compact metal-poor HII region. The electron density and chemical composition of the nebula are similar to those of normal HII regions of the Galactic disk. The radial velocity of the ionized gas coincides with that obtained from CO observations, indicating that the nebula is associated with a molecular cloud. Probably, the ionizing source of the HII region is a Herbig Be star of B0.5 spectral type.

We analyze $\tilde τ$ pair and $\tilde χ_1^0 \tilde χ_2^0$ production under the assumption $m_{\tilde χ_1^0} < m_{\tilde τ_1} < m_{\tilde χ_2^0}$, allowing the relevant parameters of the SUSY Lagrangian to have complex phases. We show that the transverse and normal components of the polarization vector of the $τ$ lepton produced in $\tilde χ_2^0$ decays offer sensitive probes of these phases.

description: Reducing tillage and increasing soil cover can enhance soil health. Conservation tillage, particularly no-till or strip-till, used in conjunction with soil cover practices (like conservation crop rotations and cover crops) can lead to a range of soil health benefits: improved agricultural productivity, greater drought resilience, and better environmental outcomes. This report uses field-level data to estimate tillage practice adoption based on soil disturbance as measured by absence of tillage operations (for no-till) and the Soil Tillage Intensity Rating (STIR, for mulch till). To gauge the intensity of tillage over time, we estimate the number of years no-till or strip-till are used over a 4-year period. Rates of adoption for practices that affect soil cover—including conservation crop rotations, cover crops, double cropping, fallowing, and residue harvest or grazing—are also estimated. The rates at which these practices are adopted in conjunction with no-till/strip-till are also estimated to illustrate interactions between tillage and practices that affect soil cover.

description: We study the quantum gravitational system coupled to a charged scalar, Dirac fermions, and electromagnetic fields. We use the "exact" or "functional" renormalization group equation to derive the effective action $Γ_0$ by integrating the flow equation from the ultraviolet scale down to $k=0$. The resulting effective action consists of local terms and nonlocal terms with unique coefficients.

description: Background: Lack of exercise, sedentary behavior, and long-time glaring at a screen have been globally urgent public health problems. These are also the main risk factors for adolescents’ health. However, the influencing factors of the sedentary behavior and the mechanism need to be further investigated, due to the specificity, contingency, and difficulty of the sedentary behavior. Purpose: To explore the influencing factors of the sedentary behavior in adolescents, construct and test the model of influencing factors of Chinese adolescents’ sedentary behavior. Methods: To investigate the influencing factors of adolescents’ sedentary behavior, and construct the model of adolescents’ sedentary behavior by interviewing 27 adolescents using grounded theory, depth interview, focus group, and a survey on 104 adolescents; to test the model by investigating 2100 adolescents using a self-report inventory. Results: the information in English in the original version. Conclusions: It has been tested that the influencing factors of adolescents’ sedentary behavior mainly include 4 categories. Future research can conduct intervention study within China to further test the efficiency of the model.

description: Every summer, a large area forms in the northern Gulf of Mexico where dissolved oxygen becomes too low for many aquatic species to survive. This “hypoxic zone” is fueled by nutrient (nitrogen and phosphorus) runoff from the Mississippi/Atchafalaya River Basin (MARB), most of which comes from agriculture. This analysis used the ERS Regional Environment and Agriculture Programming (REAP) model and data from the USDA Conservation Effects Assessment Project (CEAP) to assess the most cost-effective way of achieving a 45-percent reduction in cropland nutrient loads to the Gulf. Strategies involve adoption of management practices that reduce nutrient loss from fields to water resources, off-field practices for intercepting nutrients, retirement of marginal cropland, and other changes in crop management. Results suggest that proximity to the Gulf was a major factor in the location of nutrient-reduction efforts when reducing Gulf hypoxia was the only goal. When local as well as Gulf nutrient-reduction targets are applied, nutrient-reduction efforts are spread more evenly across the MARB. Adopting nutrient management practices, restoring wetlands, and retiring cropland to meet water quality goals also increased commodity prices, resulting in more intensive production outside the MARB and increased nutrient and sediment loadings to water in other watersheds.
Identifying physical activity behaviours and population characteristics from secondary smartphone fitness apps

description: Background: Commercial fitness and activity tracking smartphone apps are becoming ever more ubiquitous and generating a large volume of physical activity data. Utilisation of this secondary data has the potential to provide new insights into patterns of activity behaviour. Purpose: To use commercial app data to identify temporal physical activity behaviour patterns and patterns of app usage, characterising the sociodemographic features of these behaviours. Methods: Daily activity data from 30,804 app users with 7 or more days of recorded activity over the course of 2016 were used. Sociodemographic variations in physical activity behaviour and probability of meeting physical activity guidelines were investigated. Moreover, unsupervised clustering methods were applied to activity behaviours to identify temporal patterns in activity behaviour over annual and weekly timescales. Results: We ascertain longer-term patterns of app usage with increasing age and more male users reaching physical activity guideline recommendations despite longer daily activity duration recorded by female users. Key seasonal and weekly patterns of activity behaviour were identified within the app user’s data. Daylight saving was shown to play a key role in influencing activity behaviour across the clusters, with increased activity in summer months. Investigation into weekly behaviours identified varied roles of weekday versus weekend on activity levels. With some users being more active in the week and some on weekends. Conclusions: Fitness and activity tracking apps are valuable as data sources of activity over long temporal periods, allowing identification of patterns and characteristic of different socioeconomic groups, not often seen in shorter duration studies.

description: The Food Expenditure Series tracks annual and monthly trends in the U.S. food system since 1869. Produced by USDA’s Economic Research Service (ERS), the Food Expenditure Series quantifies the value of food acquisitions in the United States by type of sales outlet (e.g., grocery stores, warehouse clubs and supercenters, restaurants, recreational facilities, and so on) and product (e.g., packaged products meant for off-premises consumption, and meals and snacks meant for on-premises consumption). These data complement other USDA, ERS datasets that are used to gauge and track developments in consumer food-purchasing behaviors and the food supply. ERS researchers recently updated the methods and data used in the Food Expenditure Series, revising estimates back to 1997. Because of the extent of the changes, the comprehensive revision establishes a break with the previously published Food Expenditure Series. The trends shown in and the magnitude of the revised Food Expenditure Series estimates are comparable to household expenditure data estimated by other Federal Government agencies.
Menopausal women and physical activity

description: Background: Physical inactivity is well documented as being a key component in many non-communicable diseases of middle age and when combined with menopausal effects, finding approaches to encourage healthy lifestyle choices can be difficult. Purpose: To explore underlying factors for activity and inactivity in middle age women. Methods: This study explored the attitudes and perceptions of nine women aged 40-54 in London UK, who self-reported as exercisers or non-exercisers, to exercise participation at this life transition. The study used a grounded theory approach with theoretical sampling and semi-structured interviews. The study followed O’Brien et al.’s Standards for reporting qualitative research. Results: Four themes emerged: ‘Being middle-aged’, ‘perceptions of physical activity levels’, ‘being an exerciser’ and ‘health messaging’. Findings show that: Personal physical activity identities are relative to an individual’s previous levels of activity and measured through internal judgements of fitness improvement; participants who tried to participate in physical activity found it difficult to find appropriately targeted fitness classes and the reductive nature of health messaging meant all participants thought campaigns were not meant for them but for others. Conclusions: The mismatch of physical activity identities offers a wider understanding than objective measures alone for personal activity improvement; age-appropriate classes and population specific health messaging may improve adherence. These finding have relevance to bodies concerned with improving health outcomes in this population. Funding: N/A.

description: Lattice universes are spatially closed space-times of spherical topology in the large, containing masses or black holes arranged in the symmetry of a regular polygon or polytope. Exact solutions for such spacetimes are found in 2+1 dimensions for Einstein gravity with a non-positive cosmological constant. By means of a mapping that preserves the essential nature of geodesics we establish analogies between the flat and the negative curvature cases. This map also allows treatment of point particles and black holes on a similar footing.
