In the collection of nematodes assembled by Prof. R. T. Leiper in this department there are numerous examples of worms from game animals in different parts of the world. Amongst these the writer, in further study of the Œsophagostomes, has been privileged to examine bottles of some provisionally labelledŒsophagostomum, sp.? One lot was collected from the Roan antelope (Hippotragus equinus) by Dr. J. E. S. Old in Nyasaland, another was collected from the Wart Hog (Phacocærus æthiopicus) in Uganda by Prof. R. T. Leiper. The other bottle contained worms from the latter host collected in Northern Territory Gold Coast, by Dr. J. J. Simpson on two different occasions. A study of these specimens shows that they comprise three species new to science, and one species just recently described by Daubney (1924).

Abstract. It is a matter of current study to determine potential climate changes in different parts of the world, especially in regions like a basin which has the potential to affect socioeconomic and environmental issues in a defined area. This study provides a comparison between several climate change indices trends of two very different basins in Mexico, one located in the northern arid region (the Conchos River basin) and the other in the southern humid area (the Usumacinta River basin). First, quality control, homogenization, and completion of the missing data were applied before calculating the climate change indices and their respective trends for the combined period 1961–1994. A clear warming signal was found for the two basins in addition to an increment in the DTR, in agreement with other studies in Mexico. Also, the Conchos River basin was found to be more humid and the Usumacinta River basin drier, in accordance to a supposed seesaw behavior indicated in previous analysis.

Abstract Honey bees are very valuable to human. These social insects contribute in the pollination of many crops. Also, the products from honey bee colonies have many nutritional and medicinal benefits. Thus, keeping honey bees are very valuable and can be considered as source of income to many families. There are many diseases and pests that attack honey bee colonies. The pests attack bee colonies include: hornets, wax moths, bee-eater birds, and beetles. Such challenges can impact the survival and productivity of honey bee colonies. In this study, some beetle species belong to Fam. Nitidulidae, Dermestidae and Mycetophagidae were detected in honey bee colonies in Egypt, during spring. Despite the presence of many beetle species in the agricultural environment, only few species preferred the invasion of the colonies for feeding. These beetles do not attack stages of honey bees. They only feed on stored pollen or bee bread, especially those fallen on the bottom of the beehives. This is an alarm to follow the feeding behavior and distribution of these beetles. These beetles’ species can be considered as potential pests to weak honey bee colonies, housed in old or damaged beehives. The presence of large numbers of these beetles in weak colonies may disturb the activities of the bees and may passively impact the survival of the colonies. Listing these beetles is very important to better understanding the interaction between honey bees and beetles. On the other side, small hive beetles were not detected in the colonies. These beetles are currently one of the major problems facing honey bees in different parts of the world. This study confirms the absence of small hive beetles from Egypt.

This chapter analyzes Cultura Obrera (Labor Culture), published in New York City from 1911 to 1927. Pedro Esteve, the primary editor, gave expression to his ideas in this newspaper and while it represented Spanish firemen and marine workers, it reported on many other workers’ struggles in different parts of the world, for example, supporting and collecting funds for the Mexican revolutionary brothers Flores Magón. This newspaper, as all the anarchist press, was part of a transnational network and had a circulation not only in many parts of the United States but also in Latin American countries, including Argentina and Cuba, as well as on the other side of the Atlantic, in Spain and various European countries.

Non-western scholars usually face a dilemma if they want to pursue an international scholarly career: On the one hand, mastering western media theories is mandatory for taking part in international forums and exchanging experiences with people from different parts of the world; on the other hand, these theories are, in many aspects, foreign to their cultural backgrounds and, in many cases, seem inadequate for describing their own societies. My personal contribution to the debate arises from the fact that, although having some experience in participating in Anglophonic communication meetings and publishing in international academic vehicles, I never had first-hand experience, either as a student or as a professor, in American or European universities. In consequence, I was exposed to Western Anglophonic theories without being socialized in a scholarly environment in which they are taken as ‘natural’. Based on this experience, I contend that the global impact of western theories cannot be explained only by their intrinsic merits, but as the result of the socialization of scholars from all parts on the world in western educational institutions, and the networks built around them.

AbstractThe cooperation and aggression between five laboratory colonies of Monomorium pharaonis were compared using an aggressiveness test and pupa-carrying test in laboratory arenas. The colonies were derived from field collections in different parts of Europe and USA. Generally, inter-colony aggressiveness was low and acceptance of pupae from other colonies was high. Workers from one colony (Lužiny, CZ), however, frequently displayed aggressive behavior when paired with workers from other colonies, and the Lužiny pupae were avoided by workers of other colonies in pupa-carrying tests. Behavioral tests were only partly consistent with the phylogenetic relatedness of ants because the Wisconsin colony (USA) grouped with the Lužiny colony (and not with the other three colonies) in the phylogenetic analysis but grouped with the other three colonies in the behavioral tests.

Purpose – This paper aims to research as to how Twitter is influential as an electronic word-of-mouth (e-WOM) communication tool and thereby affecting movie market. In present days, social media is playing an important role in connecting people around the globe. The technology has provided a platform in the social media space for people to share their experiences through text, photos and videos. Twitter is one such online social networking media that enables its users to send and read text-based messages of up to 140 characters, known as “tweets”. Twitter has nearly 200 million users and billions of such tweets are generated by users every other day. Social media micro-blogging broadcasting networks such as Twitter are transforming the way e-WOM is disseminated and consumed in the digital world. Twitter social behaviour for the Hollywood movies has been assessed across seven countries to validate the two basic blocks of the honeycomb model – sharing and conversation. Twitter behaviour was studied for 27 movies in 22 different cities of seven countries and for six genres with a total tweets of 9.28 million. The difference of Twitter social media behaviour was compared across countries, and “sharing” and “conversation” as two building blocks of the honeycomb model were studied. t-Test results revealed that the behaviour is different across countries and across genres. Design/methodology/approach – The objective of the paper is to analyse Twitter messages on an entertainment product (movies) across different regions of the world. Hollywood movies are released across different parts of the world, and Twitter users are also in different parts of the world. The objective is to hence validate “conversation” and “sharing” building blocks of the honeycomb model. The research is confined to analysing Twitter data related to a few Hollywood movies. The tweets were collected across nine different cities spanning four different countries where English language is prominent. To understand the Twitter social media behaviour, a crawler application using Python and Java was developed to collect tweets of Hollywood movies from the Twitter database. The application has incorporated Twitter application programming interfaces (APIs) to access the Twitter database to extract tweets according to movies search queries across different parts of the world. The searching, collecting and analysing of the tweets is a rather challenging task because of various reasons. The tweets are stored in a Twitter corpus and can be accessed by the public using APIs. To understand whether tweets vary from one country to another, the analysis of variance test was conducted. To assess whether Twitter behaviour is different, and to compare the behaviour across countries, t-tests were conducted taking two countries at a time. The comparisons were made across all the six genres. In this way, an attempt was made to obtain a microscopic view of the Twitter behaviour for each of the seven countries and the six genres. Findings – The findings show that the people use social media across the world. Nearly 9.28 million tweets were from seven countries, namely, USA, UK, Canada, South Africa, Australia, India and New Zealand for 27 Hollywood movies. This is indicative of the fact that today, people are exchanging information across different countries, that people are conversing about a product on social media and people are sharing information about a product on social media and, thus, proving the hypothesis. Further, the results indicate that the users in USA, Canada and UK, tweet more than the other countries, USA and UK being the highest in tweets followed by the Canada. On the other hand, the number of tweets in Australia, India and South Africa are low with New Zealand being the lowest of all the countries. This indicates that different countries’ users have different social media behaviour. Some countries use social media to communicate about their experience more than in some other country. However, consumers from all over the world are using Twitter to express their views openly and freely. Originality/value – This research is useful to scholars and enterprises to understand opinions on Twitter social media and predict their impact. The study can be extended to any products which can lead to better customer relationship management. Companies can use the Internet and social media to promote and get feedback on their products and services across different parts of the world. Governments can inform the public about their new policies, benefits of governmental programmes to people and ways to improve the Internet reach to more people and also for creating awareness about health, hygiene, natural calamities and safety.

Ensuring sustainability at a tourist destination is a challenge which is faced by many nations. The challenge compounds since short term monetary gains often blind the desire for sustainable development. The term overtourism has gained popularity during the last few years as instances of anti-tourism reactions have been reported from several cities like Venice, Shimla, Barcelona, etc. An acceptable solution for countering overtourism has not yet been found because of the subjectivity and complexity of the situation. This chapter focuses on deconstructing the situation of overtourism in different parts of the world and how de-marketing can be used as one of the strategies for sustainable tourism. It shows the demarketing structure in marketing framework by modifying the 5As of tourism. It also shows the marketing mix framework within the domain of demarketing. It provides an insight into the role of de-marketing in striking a balance between the interests of local communities and stakeholders on one hand and enhancing the tourist experience at a destination on the other.

The article deals with the problem of today’s economy de-globalization in conditions of post-crisis restoration of world economy from 2009 to the present day. The author shows that de-globalization is characterized by aggravation of protectionist policy of states (especially in conditions of combating against COVID-19 pandemic) and extension of sanction regimes. It caused the relative drop in intensity of global trade and global capital flows and at the same time led to the crisis in regional integration in different parts of the world. The article systematized the most widely spread approaches of today’s researchers to the issue of de-globalization. It was found out that expectations of fast return of global economy to the former trajectory of globalization were groundless. The author shows that COVID-19 pandemic fostered disintegration processes in global economy. It was caused not only by objective need to combat against the virus but also by goals of stimulating policy of states essential for overcoming lock-down after-effects. A conclusion was drawn that, on the one hand, de-globalization conditions give states the tools for supporting national manufacturers and development of priority industries but, on the other hand, overall radicalization of political discourse could raise risks of social tension and military confrontation.
