Nature, Data, And Power: How Hegemonies Shaped This Special Section
Systems of oppression—racism, colonialism, misogyny, cissexism, ableism, heteronormativity, and more—have long shaped the content and practice of science. But opportunities to reckon with these influences are rarely found within academic science, even though such critiques are well developed in the social sciences and humanities. In this special section, we attempt to bring cross-disciplinary conversations among ecology, evolution, behavior, and genetics on the one hand and critical perspectives from the social sciences and humanities on the other into the pages—and in front of the readers—of a scientific journal. In this introduction to the special section, we recount and reflect on the process of running this cross-disciplinary experiment to confront harms done in the name of science and envision alternatives
Phase Transitions and Formation of a Monolayer-Type Structure in Thin Oligothiophene Films: Exploration with a Combined In Situ X-ray Diffraction and Electrical Measurements
A combination of in situ electrical and grazing-incidence X-ray diffraction (GIXD) is a powerful tool for studies of correlations between the microstructure and charge transport in thin organic films. The information provided by such experimental approach can help optimizing the performance of the films as active layers of organic electronic devices. In this work, such combination of techniques was used to investigate the phase transitions in vacuum-deposited thin films of a common organic semiconductor dihexyl-quarterthiophene (DH4T). A transition from the initial highly crystalline phase to a mesophase was detected upon heating, while only a partial backward transition was observed upon cooling to room temperature. In situ electrical conductivity measurements revealed the impact of both transitions on charge transport. This is partly accounted for by the fact that the initial crystalline phase is characterized by inclination of molecules in the plane perpendicular to the π-π stacking direction, whereas the mesophase is built of molecules tilted in the direction of π-π stacking. Importantly, in addition to the two phases of DH4T characteristic of the bulk, a third interfacial substrate-stabilized monolayer-type phase was observed. The existence of such interfacial structure can have important implications for the charge mobility, being especially favorable for lateral two-dimensional charge transport in the organic field-effect transistors geometry

The international events environment
Taking an explicit international approach to the subject, Events Management combines theory and practice to address the challenges and opportunities of working in a global world to help prepare students for the realities of the events management sector.
Written by a high profile international team of editors and contributors, the text features cases spanning Europe, Africa, Asia, Australia and North America, and covers key topics and issues such as fundraising, sponsorship, globalization and sustainability. It also aims to bolster student employability through the inclusion of features such as practical asides and case studies to give students a window into the real life of a practitioner.
Brand new to the third edition:
- An in-depth examination of the implications of Covid-19 for international events, including sponsorship arrangements, risk management and future job prospects for events management graduates
- Two brand new chapters covering developments in digital marketing and accessible events management
- Case studies featuring India, Australia, Peru, Europe, UK and USA and covering events such as music festivals, Holi, Mardi Gras as well as mega events such as the Olympics
- Updated theory about the critical global issues affecting events and the main drivers of change in the industry
- A companion website featuring links to interactive learning resources, an Instructors manual for lecturers, events-related videos for fun additional educational viewing, and author-selected SAGE journal articles for advanced learning.
Suitable for courses in Events Management and International Events Management
The Practical Realities of Giving Back
In this thematic section, authors consider practical ways of giving back to the communities in which they conduct research. Each author discusses their evolving thoughts on how to give back in these practical ways. Some of these authors discuss giving back by giving money, food, rides, parties, and water bottles. In other cases, authors discuss giving back by creating jobs in the short or long term, grant writing, advocacy, and education. Story-telling is also a theme that many of the authors in this section discuss. For some authors, non-material forms of giving back are critical—simply maintaining social ties to the communities in which they worked, or sharing humor. The authors consider the utility of their attempts at giving back, and in some cases present their personal philosophy or guidelines on the subject
