The purpose of this study is to investigate on themes covered by media and factors affecting coverage of climate change information in Tanzania.

In all, 85 journalists from five local media were identified using snowballing and purposive methods where quantitative methods were applied.

The results show nearly a half (49 per cent) of the journalists yet to receive training on climate change, with the majority (77 per cent) of organisations providing such training being non-local. The majority (79.8 per cent) of media houses lack editorial policies. Findings show journalists mostly cover information on climate impact and adaptation (49.3 per cent) followed by weather and climate trends (33.8 per cent), while the least covered topics are on renewable energy and climate and poverty (1.4 per cent).

The results imply journalists lack training on climate change. This may result into low and poor quality coverage of climate change information and inadequate public awareness and understanding. The study concludes that challenges in verifying information from a source, media lack of editorial policy and little exposure and access to specific internet climate change information sources may affect public agenda setting, coverage and adaptation to climate change. It is suggested that a policy be established to foster on access to climate information through frequent short training which expose journalists to new knowledge and networking.

This study contributes to literature and knowledge on climate themes reported in developing countries and factors influencing coverage of climate change.

This study aims to investigate on access and communication of COVID-19 information among Tanzanians.

Quantitative methods were applied to identify a total of 636 respondents.

Results show that the majority (86.9%) of respondents seek information on COVID-19. Gender, age, education and marital status did not influence individual’s information-seeking behaviour. Respondents largely used social media, particularly WhatsApp, to communicate. Respondents prefer blending professional and traditional information to combat COVID-19. The majority (51%) of respondents indicated that COVID-19 information was not communicated ethically. Employed people are more likely to ethically communicate information on the pandemic in social media.

Findings imply that novelty of the pandemic has enhanced active information-seeking behaviour. Respondents rely on multiple information sources to seek and collaboratively communicate COVID information. Employment status is associated with respondents’ information-seeking behaviour. Audio-visual sources are mostly preferred and relied in communicating information on the pandemic. Social media usage has enhanced timely and appropriate decision-making measures to tackle the COVID menace. Level of education has an influence on the use of credible sources and ethical communication of information on the pandemic. Utilization of COVID-19 preventive information was not statistically associated with socio-demographic variables. Availability of information infrastructures, particularly the internet, influences access, use and clear informed decision on prevention and treatment of COVID-19 disease.

The study contributes to knowledge and literature on response and preventive measures on COVID-19 pandemic in developing countries.

This paper proposes a systems framework for the analysis of economic exchange and development. Exchange is examined in the context of a social system in which actors have differential control over resources and different action opportunities and positions in a structure of social relationships. Exchange activities in a social system have ramifications in different spheres (economic and non‐economic) of social life. We focus on those ramifications which relate to social differentiation in terms of power‐unequal or differentiated action capabilities and different structural positions of actors in the social system of interaction. This perspective on exchange leads to the consideration of factors important to the emergence and maintenance of systemic, uneven development of action capabilities and to unequal dependency relationships among actors in a social system. In sum, what we wish to do in this paper is to develop a more systematic model that indicates the mechanisms whereby initial imbalances of the sort mentioned above generate social processes‐non‐economic as well as economic‐which tend to institutionalize the imbalances and perpetuate them in a self‐reinforcing manner.

The statement of the Minister of Agriculture, Fisheries and Food, coming so quickly after the ban on the use of cyclamates in food and drink in the United States, indicates that the new evidence of carcinogenesis in animals, placed at the disposal of the authorities by the U.S. F.D.A., has been accepted; at least, until the results of investigations being carried out in this country are available. The evidence was as new to the U.S. authorities as to our own and in the light of it, they could no longer regard the substances as in the GRAS class of food additives. It is, of course, right that any substance of which there is the slightest doubt should be removed from use; not as the result of food neuroses and health scares, but only on the basis of scientific evidence, however remote the connection. It is also right that there should always be power of selection by consumers avoidance is usually possible with other things known to be harmful, such as smoking and alcohol; in other cases, especially with chemical additives to food and drink, there must be pre‐knowledge, so that those who do not wish to consume food or drink containing such additives can ascertain from labelling those commodities which contain them.

This study aims to explore a paradigm for using servitization in circular supply chains, with research fields including smart, sustainable supply chains, circular economy, innovation, digital technology, product service systems and sustainability as focal areas.

A comprehensive statistical analysis of the literature on servitization, circular economy and smart supply chains reveals the history of the industry, including scholarly work, major concerns and future research prospects. The database for the analysis is provided by Scopus. Consequently, 288 research articles were reviewed, and the research trends of servitization, circular supply chains and smart supply chains from 2014 to 2022 (Q1) were covered.

The analysis reconnoitres bibliometric statistics highlighting notable authors, contemporary keywords for sifting through the literature, scientific dimensions related to smart supply chain, servitization and the circular economy, historical growth based on exploration trends and country-by-country investigation of the research field. The study also proposes a conceptual framework that illustrates how a greater emphasis on removing barriers to servitization could increase the efficiency of various circular supply chains. Given this, there is room for further research into the role servitization plays in ensuring long-term sustainability.

This paper helps to understand current scholarly publications on servitization, smart supply chains and their significance in the circular economy. It also provides a template to utilize the field’s prior accomplishments as a guide to future research opportunities.
