A Biochemical Society Focused Meeting on bacteriocins was held at the University of Nottingham on 16–18 July 2012 to mark the retirement of Professor Richard James and honour a scientific career of more than 30 years devoted to an understanding of the biology of colicins, bacteriocins produced by Escherichia coli. This meeting was the third leg of a triumvirate of symposia that included meetings at the Île de Bendor, France, in 1991 and the University of East Anglia, Norwich, U.K., in 1998, focused on bringing together leading experts in basic and applied bacteriocin research. The symposium which attracted 70 attendees consisted of 18 invited speakers and 22 selected oral communications spread over four themes: (i) Role of bacteriocins in bacterial ecology, (ii) Mode of action of bacteriocins, (ii) Mechanisms of bacteriocin import across the cell envelope, and (iv) Biotechnological and biomedical applications of bacteriocins. Speakers and poster presenters travelled from around the world, including the U.S.A., Japan, Asia and Europe, to showcase the latest developments in their scientific research.

The article presents Armand-Jean de Rancé’s reform of the Cistercian abbey of La Trappe. It positions Rancé’s ascetic programme within the wider devotional culture of seventeenth-century France, and explores in three registers the inherent dynamic between withdrawal from the world and engagement with the world. The first register concerns the abbot’s biography, the argument being that the familial, societal and ecclesiastical ircles inhabited by Rancé before and after his conversion are more closely connected than has been traditionally seen. The second is dedicated to the position of La Trappe in contemporary society and a discussion of the continuous traffic across the monastic wall of texts, guests, rumours and myths. The third involves an examination of the role of withdrawal and engagement in Rancé’s reform and its ascetic programme, showing how the abbot expounds the central notion of solitude as a place, a condition and a strategy. The article presents key insights from the author’s doctoral thesis, which was defended at the University of Copenhagen in June 2017.

The economic and political changes in the world, from the 1970s, changed the political education of the Public Institutions of Higher Education in the world. The direction of these changes was clear: the university approachedthe market and the company and created interaction mechanisms that did not exist. The article therefore reviews the academic literature that interprets the relationship between university and market/company from two perspectives: approaches that positively position of interactions, exposing their motivations, interests and forms of interaction, especially the notions on Knowledge Economy and Entrepreneurial University; approaches that observe this interaction critically and reflectively, exposing the problems of interaction, its negative aspects and the reflection of the true role of the public university from the perspective of Academic Capitalism.

The purpose of this article is to stimulate debate about the developing paradoxes and dilemmas facing the university academic. This article argues that academics are increasingly being steeped in an inauthentic existence due, at least partly to, egocentrism and sociocentrism. A modest transdisciplinary- existential analytical framework is applied as an intellectual method to reflect on the prevailing monological perspectives stifling the role of academics, in working towards building a more sustainable future. Using concepts such as the subject, facticity and transcendence, the article investigates the dialectical tensions between some of these monological perspectives and proposes avenues to create new possibilities to progress the role of the academic. The article argues that the multilogical perspectives of transdisciplinary thinking and the empowering perspectives of existential thinking can provide academics with the necessary conceptual tools to transcend egocentrism and sociocentrism. While it is likely that new contradictions will emerge as a result of this synthesis, open-minded academics are urged to ignite their imaginative powers and take up the challenge of creating and acting on new possibilities. A transdisciplinary-existential dialectical approach can provide a richer understanding of present dilemmas in academia and the world, and suggest more satisfying paths to a sustainable future.

The world is facing multiple changes and challenges; the environment shows inequalities, poverty, and corruption. Ecuador is not the exception. The man is declared the primary focus of the Ecuadorian Constitution to meet such changes. The objective of decreasing poverty, improving wealth distribution, and contributing to sustainable human development is unavoidable. In that context, the university has the pivotal role in generating interaction with society and its reality, to train professionals social and humanly responsible towards such facts, to promote the social management of knowledge from different action fields. The goal of this chapter is to specify the role of higher education institutions (HEIs) in a society where they take part, to draw up social responsibility of universities in Guayaquil and the challenges they face, as well as actions that contribute to the eradication of corruption and greater wellbeing of the society.


In the scriptural analyses presented in earlier chapters, there were many references to the emotions of Jesus, his disciples, and other characters. It will be clear by the end of this chapter that emotions play an important role in Christian and un-Christian behavior. The first section explains what emotions are and why humans have them. The second section catalogs the emotions expressed by characters in the four Gospels. It is interesting to see how the emotions expressed by Jesus were different than those expressed by other characters and also what prompted emotional reactions in Jesus. The third section generalizes the role of emotions in Christian behavior beyond the cataloging of the second section. This chapter is crucial for understanding motivations to engage in certain kinds of Christian behaviors that will help solve major problems in the world.

Knowledge may be examined from the third-person perspective, as psychologists and sociologists do, or it may be examined from the first-person perspective, as each of us does when we reflect on what we ought to believe. This chapter takes the third-person perspective. One obvious source of knowledge is perception, and some general features of how our perceptual systems are able to pick up information about the world around us are highlighted. The role of the study of visual illusions in this research is an important focus of the chapter. Our ability to draw out the consequences of things we know by way of inference is another important source of knowledge, and some general features of how inference achieves its successes are discussed. Structural similarities between the ways in which perception works and the ways in which inference works are highlighted.

Colorectal cancer (CRC) is the third leading cause of cancer death in the world, and its incidence is rising in developing countries. Treatment with 5-Fluorouracil (5-FU) is known to improve survival in CRC patients. Most anti-cancer therapies trigger apoptosis induction to eliminate malignant cells. However, de-regulated apoptotic signaling allows cancer cells to escape this signaling, leading to therapeutic resistance. Treatment resistance is a major challenge in the development of effective therapies. The microRNAs (miRNAs) play important roles in CRC treatment resistance and CRC progression and apoptosis. This review discusses the role of miRNAs in contributing to the promotion or inhibition of apoptosis in CRC and the role of miRNAs in modulating treatment resistance in CRC cells.

University portals are emerging all over the world. Portals have been perceived by many people as the technologies that are designed to enhance work and learning processes at university by making workflows simpler and information more readily available in a form in which it can be processed (Franklin, 2004). There are many benefits for having a portal in a university. First, the portal makes it easy for people to find university information targeted specifically at them. Instead of the user searching the Web for information, a person identifies himself or herself to the portal, and the portal brings all relevant information to that person. Secondly, the portal uses a single consistent Web-based front end to present information from a variety of back-end data sources. Although information about people is stored in many different databases at a university, the role of a portal is to put a consistent face to this information so that visitors do not have to deal with dozens of different Web interfaces to get their information. Usability is an important issue when designing the university portal. Principles from human computer interaction must be included in the design of portals.
