A comprehensive study of mental health issues: impact on overseas university students

Purpose: This research aimed to find out the mental problems of overseas students and how they can remove it. Research Methodology: In-depth interview method was done on the basis of Google form. After the interview, it was interpreted by thematic analysis. Results: 80% of overseas students face mental health disorders. Limitations: A larger sample size, including students residing other parts of the country should be considered in future research. The result is also difficult to generalize due to the unequal participation of male and female respondents.  Contribution: This study can be useful in those universities where overseas students study. Keywords: Overseas, Mental healt

Crop production amid climate change and river water level fluctuation at northeastern region of Bangladesh: A time series analysis

The overall goal of this study was to examine the effects of climate change on the yield of four distinct crops (Aus, Aman, Boro and Wheat) in Sylhet by using secondary climate data from 1970 to 2020. The study's other goal is to assess the impact of river water levels on crop productivity in Sylhet over time. Data on crop productivity, weather variability and river water levels were gathered from the various fields. Yield vs. climatic correlation was discovered in the study, and this correlation varied according to season. To estimate the impact of climate change on rice yield, a multiple regression model is used. Climate variables in the model were found to account for 11% of the overall variation in Aus rice yield. The relationship between relative humidity and maximum temperature is positive and statistically significant. Other variables had no effect on yield because they were not significant. Furthermore, Regression results indicated that climate variables account for 60.6 percent of the overall variation in Aman rice output. Relative humidity, on the other hand, can undermine the yield. Climate variables account for 53.5 percent of the overall variation in Boro rice output, according to the findings. As a result, an increase in rainfall may have a negative impact on Boro rice yield. Maximum and minimum temperatures might have a favorable impact on Boro rice yield. Increases in maximum temperature, on the other hand, can considerably boost Wheat yield while decreases in minimum temperature can diminish Wheat yield. On the other side, the results of the regression analysis suggest that river water level has a minor impact on Aus, Aman, and Boro yield. However, as the model demonstrates, the river water level can have an impact on wheat yield. The impact of temperature and rainfall on water level was also investigated in this study because the regression model failed to produce positive results. Surprisingly, the model performs well, despite the fact that maximum temperatures have a negative impact on water levels in the Aus and Aman seasons. This shows that if warmer temperatures aid raises Aus and Aman yields, then the water level cannot sabotage the yield rise. Rainfall has a favorable impact on the water levels in the Aus, Aman, and Boro seasons, but has a negative impact on the water levels in the Wheat season

An Economic Assessment of Production and Marketing of Winter Vegetables in Selected Char Areas of Mymensingh District

The aim of the present study was to examine the cost and return of selected winter vegetables (bitter gourd, sweet gourd and brinjal). The main objective of the study was to find out the marketing costs and margins at different marketing stages through examining the marketing system. Primary data on production and marketing costs and problems of 30 vegetables producers and 30 vegetables traders were collected by face-to-face interview method. For estimating profitability and marketing margins, mainly descriptive statistics were used in this study. Results revealed that among these three vegetables, per acre total cost of production was highest for brinjal and lowest for sweet gourd. On an average, Benefit cost ratio (BCR) was highest for brinjal (2.65) and lowest for sweet gourd (1.28). This indicates that brinjal was the most profitable vegetables in selected char areas. On the other hand, four different channels were identified in vegetables marketing system. However, the net marketing margin was highest for retailers in channel 4 for sweet gourd and lowest for faria for bitter gourd. The producers share in consumer taka was highest i.e., 65.48 percent for bitter gourd in channel 4 and price spread was lower in the same. The study also found out some production and marketing problems and constraint faced by winter vegetables producers and traders. Among them lack of capital, higher transportation cost, lack of training facilities, lack of market information, price instability etc. were main. The study also suggested some necessary measures to reduce these problems, one of which is transportation cost would be reduced by constructing a bridge over the river Brahmaputra. The bridge would also be the solution of the backwardness of char Iswardia and char Nilakshmia
