The purpose of this paper is to explore the sources of caffeine and its utilization in different food products, along with its impact on human health in terms of benefits and adverse effect.

The papers reviewed were selected based on the following key descriptors such as caffeine, sources, trends of consumption, utilization, benefits and adverse effects, regulation and labelling.

There are many physiological effects of caffeine on respiratory, cardiovascular, gastrointestinal, reproductive and central nervous system. It has a positive effect in reducing the risk of diabetes, Alzheimer’s disease, Parkinson’s disease and liver injury and, at the same time, in improving mood, psychomotor performance and immune response. On the other hand, the negative effects of caffeine include addiction, cancer, heart diseases, insomnia, gastrointestinal disturbances and intoxication. As caffeine, when taken in large amount, is harmful, therefore as per the regulatory bodies, its concentration should not exceed the set limit, and its presence needs to be listed on the label of that particular food product. In a nutshell, it can be said that caffeine acts as a boon as well as bane because it possesses both beneficial and adverse effects.

This is a unique and comprehensive review that will provide a brief overview of sources, utilization, healthful as well as harmful effect of caffeine to the readers.

In a Northern city, which claims to have more than 12,000 Commonwealth immigrants, mostly of Asian origin—Pakistanis and Indians, an increasing number of whom have been joined by their wives and families, there was instituted in 1965 a routine examination of their children before school entry, later extended to children of immigrant origin already in the schools. This examination extended to haemoglobin estimation, tuberculin‐testing and, equally important, examination of the stools for pathogens and parasitic ova. 419 entrants were examined in the first half of 1965 and 898 pupils. Parental co‐operation must have been excellent, as parents all agreed, without exception, to the special examination, although to some extent, there might have been considered legal authority in the current School Health Service (Medical Inspection) Regulations made under the Education Act, 1944. We are not aware of any report of intestinal pathogens, but helminth infestations were reported (Archer D. M., Bamford F. N., and Lees E., Helminth Infestations in Immigrant Children, 1965, Brit. Med. J., 2, 1517), from which it appears 18·6% carried five types of worm, of which the commonest was hookworm. It would be fair to assume that helminth infestation, indicating as it does, exposure to food infections, water‐borne disease and environment generally, is an index of gastro‐intestinal infection and the presence of pathogens, including the carrier state.

The purpose of this paper is to explore the health effects and safety aspects regarding the consumption of energy drink (ED).

A wide variety of publications was identified through electronic databases (ScienceDirect, PubMed, SciELO, Google Scholar, Link springer and ResearchGate) on the basis of different keyword such as composition, market status, consumption pattern, health effects, consequences and policies related to ED consumption.

Owing to its popularity, various brands of EDs have been introduced in the market along with a wide variety of modifications to attract the consumers of all age groups. EDs comprise majorly active ingredients such as caffeine, taurine, guarana, L-carnitine and glucoronolactone, ginseng and sweeteners. EDs are well known to have good taste, enhance energy levels, physical alertness and performance, but they also pose risk of certain health hazards, i.e. caffeine intoxication. Because of this, different policies have been formulated by various regulatory bodies of respective countries regarding the composition, labelling, distribution and sale of EDs.

This review will provide a brief overview of composition, market status, consumption pattern, health effects, consequences and policies related to ED consumption.

A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.

The prayer against the Poultry (Hygiene) Regulations which we briefly mentioned in the editorial of our last issue, was lodged as a result of activity by the Environmental Health Officers' Association. Incidentally it is the first occasion as far as we can recall that a prayer has been lodged against any of the rash of food regulations of recent years, and reflects the strong feelings of the public health inspectorate.

Every seaport with foreign‐going shiping trade has always had its “foreign” quarters; every large city hat had its Oriental traders and services, eg., Chinese laundries, Indian restaurants, Italian restaurants, greengrocers, ice cream and biscuit manufacturers; all of which has meant that foreign foods were not unknown to food inspectors and the general public in its discerning quest for exotic food dishes. It was then largely a matter of stores specially stocking these foods for their few users. Now it is no longer the coming and going of the foreign seaman, the isolated laundry, restaurant, but large tightly knit communities of what have come to be known as the “ethnic minorities”, from the large scale immigration of coloured peoples from the old Empire countries, who have brought their families, industry and above all their food and eating habits with them. Feeding the ethnic minorities has become a large and expanding area within the food industry. There are cities in which large areas have been virtually taken over by the immigrant.

The pervasive spread of digital technologies brought an incredible boost in data availability. Companies are dealing with massive amount of data that wait to be exploited. At the same time, scholars are providing different strategies and methods to help companies capture the value embedded in their data to foster innovation and improve the efficiency of existing processes. In these research studies, data are the by-product of something else, and they are a silent asset that needs to be exploited. What if data might be considered the final goal? The paper aims to discuss these issues.

The research is based on an exploratory multiple case study analysis, on the basis of three cases used as an illustration for new ideas. In particular, the gathered data are analyzed according to models previously presented in the literature review, building on and expanding them.

The research proposes a data-driven approach to innovation, offering a peculiar view of the innovation process. The trigger point is the need of data that let begin the entire development process of a complex system. In this perspective, the application that data are a by-product of the entire innovation process and not the primary output is peculiar since the vast majority of the literature consider data as the by-product of the primary product.

Future research is needed to assess the replicability of the model outside the mobile app industry and to measure its performances. Nevertheless, this paper provides insights both for scholars and managers, enlarging the discussion on digital innovation and digital business models.

The results provide a development process to foster innovation relying on the need of data as the trigger point, guiding entrepreneurs and managers in the building process of the entire digital system.

Previous research studies often considered Big Data (BD) in innovation as a way to enlarge the current product offer or to make the innovation process more effective or efficient; this paper changes the perspective by considering BD as the trigger and the enabler of the entire digital innovation process.

This study aims to observe the coloring efficacy of coffee-based natural brown colorant for cotton dyeing under microwave (MW) treatment.

The colorant extracted in particular (neutral and acidic) media was stimulated by MW treatment up to 6 min. Dyeing variables were optimized and 2–10 g/100 mL of sustainable anchors (mordants) have been used to get colorfast shades.

It has been found that un-irradiated acidic extract (RE) containing 5% of table salt at 80 °C for 50 min has given high color yield onto MW-irradiated cotton fabric (RC = 2 min). The utilization of 2% of Fe, 10% of tannic acid and 10% of sodium potassium tartrate before bio-coloration, whereas 4% of Fe, 10% of tannic acid and 6% of sodium potassium tartrate after bio-coloration has given good color characteristics. In comparison the application of 6% of pomegranate and turmeric extracts before bio-coloration and 6% of pomegranate and 10% of turmeric extracts after bio-coloration have given good color characteristics. New bio-mordants can be added to get more new colorfast shades.

There is no research limitation for this work. New bio-mordants can be added to get more new colorfast shades.

This work has practical application for artisans, textile industry and handicrafts. It is concluded that colorant from coffee beans can be possible alternative of synthetic brown dyes and inclusion of MW rays for extraction and plant molecules as shade developers can make process more green.

Socially, it has good impact on eco-system and global community because the effluent load is not carcinogenic in nature.

The work is original and contains value-added product for textiles and other allied fields.

To address safety risks, worker well-being concerns and productivity losses in construction due to substance misuse, this study aims to explore awareness and usage levels of various substances among Nigerian construction professionals. The findings aim to inform targeted interventions and policy development to tackle these industry-specific challenges.

A comprehensive literature review identified several substances and intoxicants commonly used in construction, which informed the development of a well-structured questionnaire. This questionnaire was distributed to both construction professionals and nonprofessionals. The Shapiro-Wilk test assessed the normality of awareness and utilization scores for each substance, while the Kruskal-Wallis H-test explored significant differences in awareness and usage scores among different respondent groups.

Despite reporting low awareness of substances commonly used in construction, a significant proportion (over 60%) of respondents admitted to using several of these substances in their construction activities. This highlights a concerning disconnect, with more than half (62.5%) exceeding a predefined threshold (3.5) for significant substance use. Ten out of the 16 substances surveyed fell into this category, indicating a widespread issue within the industry.

The findings of this study highlight the need for increased education and awareness programs about the dangers of substance misuse in the construction industry. Construction companies should implement regular training sessions and workshops to educate workers on the risks associated with substance use. Additionally, there should be stricter enforcement of substance use policies and routine substance testing to deter misuse. These measures can enhance safety, improve worker well-being and boost overall productivity in the construction industry.

The insights from this study can inform the development of international policies and best practices for substance use prevention and worker well-being in the construction industry. Sharing these findings with international organizations, policymakers and industry stakeholders can help create broader guidelines and frameworks adaptable for implementation in various countries.
