Abstract
Purpose
The purpose of this paper is to evaluate the viscoelastic quality of commercial vital wheat glutens from different origins (A and B) through simple tests, and correlate these results with dough rheological parameters measured using more complex equipment (farinograph and extensograph) and with bread quality characteristics (specific volume and crumb firmness) obtained from wheat flour fortified with 7 g/100 g of vital gluten.
Design/methodology/approach
For the evaluation of vital gluten quality, two commercial vital wheat gluten named A and B were used. The simple tests performed with these samples were wet and dry gluten contents and index gluten, extensbility test and expansion test. The Pearson correlation was performed among data from dough rheological tests (farinograph and extensograph) and bread quality parameters (specific volume (SV) and crumb firmness) obtained from the fortification of wheat flour with 7 g/100 g of VGA or VGB (previous work, data not shown).
Findings
The simple tests showed differences in the viscoelastic properties of vital gluten A and B; vital gluten A presented higher elasticity and lower extensibility than vital gluten B, and the gluten ball of sample A presented higher SV. By correlation analysis, it was verified that the simple tests studied may be useful to assess the baking performance of commercial vital gluten when this product is added to wheat flour for its fortification. Furthermore, the results indicate the need for more information on vital wheat gluten proteins for its commercialisation and use.
Originality/value
This work is very important, not just for the scientific community, but also for the bakery industry, that requires more information about vital wheat gluten before its use in bread making. As there are great differences in the protein quality of commercial vital wheat glutens and their functionality, the study was developed to solve this problem.

Abstract
“All things are in a constant state of change”, said Heraclitus of Ephesus. The waters if a river are for ever changing yet the river endures. Every particle of matter is in continual movement. All death is birth in a new form, all birth the death of the previous form. The seasons come and go. The myth of our own John Barleycorn, buried in the ground, yet resurrected in the Spring, has close parallels with the fertility rites of Greece and the Near East such as those of Hyacinthas, Hylas, Adonis and Dionysus, of Osiris the Egyptian deity, and Mondamin the Red Indian maize‐god. Indeed, the ritual and myth of Attis, born of a virgin, killed and resurrected on the third day, undoubtedly had a strong influence on Christianity.

Abstract
SIDE by side with a steady reduction in the natural resources of the world there is a rapid increase in the amount of information available on almost every subject. Every year human beings generate more knowledge in the social, economic and scientific fields. So vast is the flood that the task of finding relevant information on a particular subject at the right time is of a magnitude impossible to imagine fifty years ago.

Abstract
Purpose
This study aims to understand how Gen Z consumers perceive fashion brands’ corporate social responsibility (CSR) communication through emotional appeals on Instagram and how such perception affects their overall behaviour towards the brand.
Design/methodology/approach
The study adopts a qualitative research approach through photo-elicitation and 14 semi-structured in-depth interviews with members of Gen Z, using one of the world’s largest fast fashion brands, H&M, as the study context.
Findings
It is increasingly difficult to capture the attention of Gen Z as they have become immune to the typical CSR messages despite attempting to appeal to their emotions. This makes CSR communication alone challenging in influencing brand perception. However, behaviour towards the brand, such as purchase intention, is not necessarily dependent on whether consumers are convinced of the brand’s CSR activities, as greater value is placed on fast fashion’s price and availability. For Gen Z, such elements surpass their concern for sustainable fashion. Since more emphasis is placed on neutral endorsers due to their trustworthiness, CSR efforts may be disseminated through such third parties to achieve desired outcomes.
Practical implications
Understanding consumers’ perceptions of the current CSR effort allows brand managers to reevaluate their CSR communication strategies to appeal to Gen Z and encourage positive brand behaviour.
Originality/value
Contrary to previous studies, which have focused on organisational outcomes, the study has in-depth explored consumers’ perception of CSR efforts on Instagram and the implications of such perceptions for long-term brand building.

Abstract
Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

Abstract
The mammoth proportions of Public Expenditure, its accountability, its control, must be one of the biggest problems any government has had to meet. Despite all its counselling to the public spenders, its massive efforts to scale down the spending, there is extremely little to show for it. The Departments and State Services have become so large, they have outgrown government control; they are in fact forms of government in themselves. When a body established with a definite role becomes so big and powerful, as many of the authorities in the country have become, they tend to resent any form of control over them. History has many such examples in one form or another. Where an ocean divides them, the subordinate power may seek a separate nationhood for itself, as the American colonies did a couple of centuries or more ago. They chose the right moment to rebel when the home government sought to pass on extra levy on the importation of tea, which the Colonists turned into a slogan “no taxation without representation”. The truth, however, was they had outgrown the mother country and saw themselves as a new nation in a new land immensely rich in natural resources, riches all theirs for the taking. Much of the old country understood their aspirations and in the final settlement, the British were more than generous to them.
