The study has been applied for measuring productivity, profitability and efficiency of shrimp (Penaeusmonodon) farming in Bangladesh. It was found that per hectare gross return (GR), net return and gross margin were Tk. 364,222, Tk. 215,931 and Tk. 260,095, respectively, and Benefit Cost Ratio was 2.46 for shrimp farming. All the explanatory variables had a positive and significant effect, except for cost of lime had a negative and insignificant effect on the GR of shrimp farming. Efficiency analysis indicated that most of the farmers inefficiently used their inputs. This study also identified some of the problems faced by the farmers associated with shrimp farming.
Bangladesh is predominantly an agricultural country. Agriculture provides employment to nearly about 47.33 percent of its total labor forces (BER, 2015). Broad agriculture sector which includes crops, livestock, fisheries and forestry contributes 16 percent to the Gross Domestic Product (GDP) as a whole in the FY 2013-14 (BER, 2016). Mymensingh district was selected for the study to calculate the profitability and to assess the resource use efficiency of Boro rice production. Simple random sampling technique had been used for collecting data from 60 sample farmers through interview schedule. Both descriptive studies and functional analysis was done to achieve the objectives of the study. The findings of the study revealed that per hectare gross return, net return, and gross margin were found to be BTD110680.00, BTD 25208.94 and BTD 48158.95, respectively. Total costs of rice production were calculated at BTD 85471.06 per hectare. Benefit Cost Ratio (BCR) was found to be 1.29 for Boro rice production. Thus it was found that Boro rice production was profitable. Production function analysis suggested that, among the variables included in the model, quantity of seed, animal labor and power tiller cost, No. of human labor, quantity of fertilizer, cost of irrigation, had a positive and significant effect on the gross yield of Boro rice production, except for cost of manure and cost of pesticides had an insignificant effect on the gross yield of rice production. Efficiency analysis indicated that most of the farmers inefficiently used their inputs. This study also identified some problems associated with Boro rice production. Problems faced by the farmers were ranked on the basis of corresponding percentages. This study provides appropriate suggestion and policy recommendations which will help the development agencies and policy makers of the country for improving the livelihood of the people in the study area.

, one of the most challenging unprecedented global pandemics of human history, has changed people's work life and social life tremendously. Wearing a face mask is one of the most visible habits that people had to adapt to reduce the transmission of the Coronavirus. The primary purpose of this study was to investigate the impact of respondents' sociodemographic factors and working place on their face mask purchasing behavior during the COVID-19 pandemic in the USA. Secondary cross-sectional data were used in this study. An online survey administered on social media (between 20-30 March 2020) was used to collect data from adult research participants that reside in the United States through Qualtrics. From total of 6602 data, after deducting the missing values, 4949 data were used in this study for further analysis. The binary logistic regression model was used to conduct the study. The study found gender, age, education, and workplace as significant factors that influence people's face mask purchasing behavior. In addition, college education, gender, and workplace are positively associated with face mask purchase. Conversely, young age is negatively associated with respondents' face mask purchases. Though the study has limitations in the case of data representation and uses only a few variables, its findings provide some critical insights to the marketers to restructure their market segmentation. Besides, results could offer essential understandings to the relevant stakeholders, who are working to ensure face cover by people to reduce transmission of Coronavirus.
