Biometric indices of eleven mangrove fish species from southwest Bangladesh
شاخص های بیومتریک یازده گونه ماهی حرا از جنوب غربی بنگلادش-2021 Biometric indices, i.e. i) length-weight relationships (LWRs), ii) form factor (a3.0), iii) length-frequency distributions (LFDs), and iv) condition factors (relative KR and Fulton’s KF) are considered to be very cru- cial in the assessment of fishery studies as they provide information on fish population growth and coastal habitat well-being. The study of biometric indices of mangrove fish has, however, received little attention. Our research investigates the LFDs, LWRs, a3.0, KR and KF of 395 individuals from nine families (Latidae, Engraulidae, Gobiidae, Mugilidae, Synbranchidae, Schilbeidae, Scatophagidae, Plotosidae, and Terapontidae). The LFDs showed that the lowest total length (TL) was 4.57 cm for Stolephorus tri, and highest TL was 56.20 for Monopterus cuchia. The LWRs showed that the b (allometric coefficient) values ranging from 2.01 (Plotosus canius) to 3.29 (Terapon jarbua), appeared as highly significant (P < 0.001). Moreover, the KR values ranged from 0.80 to 1.36, which indicate a good state of health of the population. Our findings could be useful in updating the FishBase (online database) and tracking mangrove fish spe- cies sustainably.© 2021 National Institute of Oceanography and Fisheries.

Nurses knowledge, skills and preparedness for disaster management of a Megapolis: Implications for nursing disaster education
دانش، مهارت و آمادگی پرستاران برای مدیریت بلایا در یک کلانشهر: پیامدهایی برای آموزش پرستاری در بلایا-2021 As frontline health caregivers, nurses must be adequately prepared to respond effectively to disasters. Therefore,
it is necessary to assess nurses’ disaster management capacity to know their preparedness levels, especially for a
densely populated Megapolis like Dhaka, which is at high risk of disasters. Thus, the study aimed to examine
Dhaka city nurses’ knowledge, skills, preparedness (KSP) for disasters and explore the factors influencing the KSP
levels. A self-explanatory descriptive survey questionnaire was developed adopting the Disaster Preparedness
Evaluation Tool (DPET) in Bangla language for quantitative data collection. Following multistage sampling, 410
nurses’ data were collected from eight hospitals in Dhaka city. The nurses in Dhaka city had moderate levels of
knowledge, skills, and preparedness for disaster management, reflecting that they need more development to
deal with disasters effectively. Moreover, multiple linear regression analyses indicate that nurses’ disaster
knowledge, skills, and preparedness scores were significantly positively associated with training on disaster
management (p < 0.001) and disaster response experience (p < 0.001). In addition, one-half of the respondents
demanded more drills and exercises on disaster management in their workplaces to enhance their disaster skills
and preparedness. Furthermore, disaster education should be incorporated into the nursing curriculum, which
would play a seminal role in preparing them for future disaster management. keywords: آمادگی در برابر بلایا | دانش بلایا | مهارت ها | داکا | پرستاران | مدیریت بلایا | بنگلادش | Disaster preparedness | Disaster knowledge | Skills | Dhaka | Nurses | Disaster management | Bangladesh |

Modelling of supply chain disruption analytics using an integrated approach: An emerging economy example
مدل سازی تجزیه و تحلیل اختلال در زنجیره تامین با استفاده از یک رویکرد یکپارچه: یک مثال اقتصاد در حال ظهور-2021 The purpose of this paper is to develop a framework to identify, analyze, and to assess supply chain disruption factors and drivers. Based on an empirical analysis, four disruption factor categories including natural, human- made, system accidents, and financials with a total of sixteen disruption drivers are identified and examined in a real-world industrial setting. This research utilizes an integrated approach comprising both the Delphi method and the fuzzy analytic hierarchy process (FAHP). To test this integrated method, one of the well-known examples in industrial contexts of developing countries, the ready-made garment industry in Bangladesh is considered. To evaluate this industrial example, a sensitivity analysis is conducted to ensure the robustness and viability of the framework in practical settings. This study not only expands the literature scope of supply chain disruption risk assessment but through its application in any context or industry will reduce the impact of such disruptions and enhance the overall supply chain resilience. Consequently, these enhanced capabilities arm managers the ability to formulate relevant mitigation strategies that are robust and computationally efficient. These strategies will allow managers to take calculated decisions proactively. Finally, the results reveal that political and regulatory instability, cyclones, labor strikes, flooding, heavy rain, and factory fires are the top six disruption drivers causing disruptions to the ready-made garment industry in Bangladesh. Keywords: Supply chain management | Disruption factors and drivers | Fuzzy analytic hierarchy process | Delphi method |

Factors influencing the adoption of mHealth services in a developing country: A patient-centric study
عوامل مؤثر بر اتخاذ خدمات بهداشتی و درمانی در یک کشور در حال توسعه: یک مطالعه بیمار محور-2020 mHealth under the umbrella of eHealth has become an essential tool for providing quality, accessible and equal
health care services at an affordable cost. Despite the potential benefits of mHealth, its adoption remains a big
challenge in developing countries such as Bangladesh. This study aims to examine the factors affecting the
adoption of mHealth services in Bangladesh by using the extended Unified Theory of Acceptance and Use of
Technology (UTAUT) model with perceived reliability and price value factors. It also examines the moderating
effect of gender on the intention to use and on the actual usage behavior of users of mHealth services. A wellstructured
face-to-face survey was employed to collect the data. Structural equation modeling (SEM) with a
partial least squares method was used to analyze the data collected from 296 generation Y participants. The
results confirmed that performance expectancy, social influence, facilitating conditions and perceived reliability
positively influence the behavioral intention to adopt mHealth services. However, effort expectancy and price
value did not have a significance influence on the behavioral intention. Moreover, Gender has a significant
moderating effect on mHealth services adoption in certain cases. Finally, the theoretical and practical implications
of this study are also discussed. Keywords: mHealth | Developing countries | UTAUT model | Generation Y | Bangladesh |

Life in riverine islands in Bangladesh: Local adaptation strategies of climate vulnerable riverine island dwellers for livelihood resilience
زندگی در جزایر رودخانه ای در بنگلادش: استراتژی های سازگاری محلی ساکنان جزیره رودخانه ای آسیب پذیر در برابر آب و هوا برای تاب آوری معیشت-2020 Adaptation is a key tool to reduce the climate change vulnerability of rural people whose livelihood is dependent
on agriculture. An appropriate policy and strategy cannot be effective without a proper understanding of peoples’
climate change perception. This study intends to explore the local adaptation strategies of the riverine
island (char) dwellers in the face of climate change hazards through a survey of 374 char dwellers living in the
flood and riverbank erosion prone geographically isolated areas in Bangladesh. The study reveals almost no
difference between the perception of char dwellers and the observed data on climate change. It further reports
that the climate impacts make the char households a vulnerable community and minimize their livelihood
resilience. A number of local adaptation strategies are adapted by char dwellers in the face of climate change
effects which enhance their livelihood resilience. The study further reveals that homestead gardening, changing
cropping pattern, tree plantation and migration are the most common strategies adapted by char dwellers. The
study suggests that continuous development program and riverine island-based disaster management projects
should be executed through an effective monitoring for enhancing char dweller’s livelihood resilience. Keywords: Climate change | Vulnerability | Disaster management | Resilience | Sandbar |

How can NGOs support collective action among the users of rural drinking water systems? A case study of Managed Aquifer Recharge (MAR) systems in Bangladesh
چگونه سازمان های غیردولتی می توانند از اقدامات جمعی در بین کاربران سیستم های آب شرب روستایی حمایت کنند؟ مطالعه موردی سیستم های مدیریت شارژ آبخوان (MAR) در بنگلادش-2020 In this article, we link NGO-supplied drinking water infrastructure projects with collective action development
approaches. Although governing local, shared drinking water systems (DWS) requires users to
act collectively, users rarely organize such collective action successfully by themselves. Nongovernmental
organizations (NGOs) are therefore frequently called upon to support local communities
to set up or consolidate the kind of local collective action required for governing DWSs. However, the
effectiveness of such forms of NGO support remains unclear. Therefore, this paper attempts to assess
the form and impact of this kind of NGO support. Combining insights gained from theory on institutions
for collective action in the context of shared resource systems, we develop a set of requirements presumed
necessary for guaranteeing both day-to-day and long-term collective action among local shared
DWS users. We apply this framework to empirically explore if, how and why NGO support targets these
requirements, and whether this support influences users’ capacity for collective action. To this end we
examine 11 cases where NGOs have worked with users of Managed Aquifer Recharge (MAR) systems
in Bangladesh. We collected data through focus group discussions, semi-structured interviews with local
leaders, NGO officials, and project staff, and by reviewing project documentation. We find that NGO support
favors long-term requirements over the requirements for day-to-day collective action. NGO activities
seem based on applying standard approaches to training and awareness raising, and less on
empowering users to craft their own solutions. A case for a lasting impact of NGO support on any of
the requirements is hard to make. Our results imply that when attempting to organize effective and
long-lasting forms of collective action among the users of shared resource systems, both NGOs and commissioners
of projects need to engage more explicitly in learning what works and what doesn’t. Keywords: Non-governmental organizations | Community management | Collective action | Managed aquifer recharge | Drinking water systems | Bangladesh |

Fisheries co-management in hilsa shad sanctuaries of Bangladesh: Early experiences and implementation challenges
مدیریت شیلات در پناهگاه های هیلسا از بنگلادش: تجربیات اولیه و چالش های اجرایی-2020 Community-based fisheries management has long been practiced in the management of the inland fisheries of
Bangladesh. However, formal coastal co-management has only been implemented recently in hilsa shad (Tenualosa
ilisha) sanctuaries. The study analysed the pre-implementation processes, institutional arrangements,
implementation activities, as well as challenges for fisheries co-management that are currently being implemented
in the Padma-Meghna riverine-estuarine system. As a first step in establishing a co-management system
in hilsa shad sanctuaries, communities (both fishing villages and fish landing centres) were selected for interventions.
Co-management committees were formed from the community-village to district level with the
defined tasks of developing plans and programs, implementing management rules and regulations, monitoring
compliance, and creating awareness in a cost-effective manner among various stakeholders. Still, the operationalization
of co-management in this large riverine-estuarine system is a challenging task. To overcome these
challenges, several issues had to be considered through lessons learned from previously implemented
community-based fisheries management projects in Bangladesh. To ensure that fisheries co-management is
functional, the institutional framework needs to be flexible with support from local government institutions and
NGOs. The boundary of the management unit needs to be clearly defined and community-based organization also
needs a clear legal status. To make co-management sustainable, a relationship of trust and respect among comanagement
partners needs to be developed and maintained. The effective implementation of fisheries comanagement
will require an inclusive compensation scheme that will motivate stakeholders to comply and
maintain fisheries management efforts through collective action. Keywords: Hilsa sanctuaries | Co-management | Small-scale fisheries | Implementation challenges |

Does quality stimulate customer satisfaction where perceived value mediates and the usage of social media moderates?
آیا کیفیت در جایی که ارزش ادراک شده واسطه و استفاده از رسانه های متوسط است رضایت مشتری را تحریک می کند؟-2020 Customer is considered as the king in the world of business. The issue of customer satisfaction in electronics home appliances has received greater attention from academics and practitioners. In other words, customer satisfaction is a vital consideration in marketing. With the development of technology, new and innovative electronic home appliances are available in the market. Customers purchase and use the costly electronic home appliances where the satisfaction issue is an important concern. In Bangladesh, working families find the electronic home appliance very necessary. Companies offer state-of- the-art appliances for customers household works. Therefore, the study intends to investigate the effect of product quality (PQ), quality of service (SQ) and perceived value on customer satisfaction (CS). In addition, this study also seeks this relationship shaped by customers perceived value (CPV) as a key mechanism and interacted by social media usage. A total of 300 households were selected on a judgmental basis from Dhaka city in Bangladesh using a structured questionnaire. Collected data were CB-SEM (AMOS-v24) and SPSS. The findings showed PQ and SQ have positive effects on CS; SQ affects, but PQ does not affect CPV. CPV has a mixing mediating effect on SQ and CS relationship and PQ and CS relationship. Importantly, the positive impact of PQ, SQ and CPV is greater on customers who exhibit higher social media use. The conceptual framework was buttressed by EDT theory. The study contributed to contextual and theoretical knowledge in regards to home appliances. The practicing managers can collect an insight of customer satisfaction for their business.

Farmers’ perceptions and management of risk in rice/shrimp farming systems in South-West Coastal Bangladesh
برداشت کشاورزان و مدیریت ریسک در برنج / میگو و سیستم های کشاورزی در جنوب غربی ساحل بنگلادش-2020 Farmers in Bangladesh face considerable risk due to fluctuations in biophysical and economic conditions, but the
response to these risks is poorly understood. In particular, there is a need to better understand the endogenous
management of risk in the rice/shrimp farming systems that have emerged in the inner coastal zone of
Bangladesh. This paper draws on a case study of a typical rice/shrimp farming village in Khulna District to
explore: (a) farmers’ perceptions of risks and their management responses, (b) risk-return trade-offs within
small-, medium-, and large-farm households, and (c) the role of other farm and non-farm activities in mitigating
risks to household livelihoods. Farm-level data were collected through a reconnaissance survey, a village census,
household case studies, and a sample survey of 73 households. Representative farm budgets were constructed for
the three farm-size classes. The key performance indicators calculated were gross margin (GM), net income (NI),
and GM per workday of family labour. The riskiness of the rice/shrimp system was assessed for each farm type
using farmers’ estimates of low, normal, and high yields and prices to specify triangular distributions.
Cumulative distribution functions (CDFs) for GM, NI, and GM per workday were generated. A whole-farm
economic analysis was also conducted to assess the relative contributions of different sources of income for each
farm type. With access to saline water for shrimp farming in the dry season and fresh water for rice in the wet
season, farmers have developed and progressively adapted an alternating rice/shrimp farming system that has
minimised the trade-offs between the two crops and provides a good return to household and village resources
for all farm types. The system is subject to significant production and market risks, especially the shrimp
component. However, farmers have clearly perceived these risks and ameliorated them through a range of
production, marketing, and management strategies. With these risk management practices, the rice/shrimp
cropping system is economically viable, given the current variation in yields and prices. The greater risk associated
with the shrimp component was offset by the renewed stability of the rice component over the past
decade, and the risks of the whole cropping system were offset by other farm and non-farm sources of livelihood.
Development interventions need to work with farmers to provide further options (suitable rice varieties, solutions
to shrimp disease, improved village and transport infrastructure) if this resilience is to be maintained. Keywords: Production risk | Market risk | Risk management | Rice | Shrimp | Farming systems | Farm economics | Coastal environment | Sustainability |
