Plastic bag is the cheapest and most available means to carry goods. However, mass use and improper disposal of this product generate severe environmental issues in developing countries. Bangladesh promulgated nationwide ban on plastic bag in 2002 as a protective measure for safeguarding environment and ecosystem. This study investigates the effectiveness of the ban in the south-west region of Bangladesh. A total of 180 randomly selected retailers from six upazilas of three districts in the south-west region of Bangladesh were surveyed taking one rural and one urban agglomerate from each district. More than three-fourths of the retailers provide plastic bag to the customers and only four percent retailers provide jute bag. Our findings suggest that the efficacy of authority to execute the ban is insignificant that generates the scope of violating the banning efforts of plastic bag. The retailers endorse that lack of alternative bag is the reason behind violating the ban on plastic bag. The logistic regression results suggest that frequency of raid by public authority, non-availability of alternative product, lack of knowledge regarding deteriorating impact of plastic bag on ecosystem and environment, and business license significantly influence the retailers to comply with the enforcement of banning plastic bag, whereas the proximity of shop to the main road provides room for non-compliance. This study suggests for easy availability of environment friendly bag, awareness among mass people and frequent raid from the authority which will contribute in environmental protection and ecosystem restoration through effectively enabling the ban.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125626936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The levels of elements including Fe, Mn, Zn, Cu, Cr, Cd, Pb, and As were evaluated using the flame-AAS and HG-AAS methods followed by Nitric Acid (HNO3)-Perchloric Acid (HClO4) digestion. The results revealed that the concentrations of Fe, Mn, Cr, and As were higher than the WHO and FAO recommended levels. Maximum concentrations (mg/kg) of Fe, Mn, Cr, and As were observed as 104.00 ± 8.30 in Tilapia (O. mossambicus) from gheer #3, 3.40 ± 1.71 in Tilapia (O. mossambicus) of gheer #3, 12.80 ± 1.45 in golda (M. rosenbergii) of gheer #1, and 1.96 ± 0.09 in Tilapia (O. mossambicus) from gheer #3, respectively. But on average, M. rosenbergii was discovered to contribute more to the maximum level of almost every metal compared to the other two species, whereas species from gheer #3 were found to be more contaminated.

This review considers 4658 documents extracted from Scopus by performing a search with the words 'migration', 'climate change', 'climatic hazard' and 'coastal region' covering journal articles, review papers, book chapters, books, and conference papers from 2011 to 2020. This study applied VOSViewer for analysis. Results reveal that climate change is a dominant driver of migration, and the literature is deeply rooted in the United States and the United Kingdom. The lexical network shows that the developed countries which are less vulnerable to climatic hazards produce more co-authored documents. Furthermore, in the migration discourse, the co-authors from developed countries have strong ties exhibiting migration and climate change research, mainly concentrated among the collaborative framework of developed countries’ researchers. Therefore, more research on migration and climate change issues in collaboration with the global south and north is highly demanding, providing further insights into the existing research arena.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132801292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using statistical techniques such as multiple regression methods, the study found a significant relationship between pedagogical practices and the course-level performance of university students. We constructed three indexes, namely the communication skill index, subject knowledge index, and teaching strategy index covering 12 teaching practices of teachers. The analysis showed that an increase of one decimal point in the value of each of these indexes led to an average increase in the course grade by 0.53, 0.58, and 0.62 units, respectively. The study also found that personal attributes of students, such as their interest in the course and total study hours, were significant determinants of academic performance.

The effect of salinity and parent-of-origins on the new leaf production and leaf area of the mangrove A. officinalis in the less salinity zone (LSZ), moderate salinity zone (MSZ) and high salinity zone (HSZ) of the Sundarbans were studied under experimental conditions in a randomized block design. The results of the experiment highlighted that the number of new leaf production and leaf area of A. officinalis from the less, moderate and high salinity zones were reduced significantly (p<0.05) with the increase in salinities. Yet, new leaf numbers as well as leaf area of this species did not differ significantly (p<0.05) between and among the three salinity zones from 0 to 20 ppt salinities. However, from 25 ppt and above salinities, the new leaf numbers and leaf area of the moderate and high salinity zones were significantly higher (p<0.05) compared to less salinity zone. Hence, saline environments and parental origins affected leaf neogenesis, and thereby influence the growth of this species. Therefore, the seedlings of A. officinalis of moderate and strong salinity zones origin can sustain in the increasing saline environments, and thereby contribute to the sustainable vegetation cover of the Sundarbans. Further, A. officinalis seedlings generating from the MSZ and HSZ can be used for mangrove plantation establishment in the high salinity areas of Bangladesh.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133704794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
