Adults' experiences of trying to lose weight on their own: findings from three qualitative syntheses

Series
Evidence-Based Health Care
Embed
Jamie Hartmann-Boyce is a Senior Researcher in Health Behaviours, based at the Nuffield Department of Primary Care Health Sciences, University of Oxford. Her work focusses on obesity and tobacco control and her particular interests lie in evidence synthes

Though the vast majority of people trying to lose weight do so on their own, without support from healthcare professionals or formal weight loss programmes, most research into weight loss focuses on more intensive programmes. We therefore set out to find out more about what people do when trying to lose weight on their own. As part of this work, we conducted three qualitative systematic reviews to explore people's experiences with self-directed weight loss. The first review provides an overview of the cognitive and behavioural strategies used during self-directed weight loss attempts, and the second two reviews delve further into particular weight loss strategies that emerged as part of the overview, namely self-monitoring and reframing. In this talk, I'll cover key findings from each of the three reviews, and also use these reviews to illustrate how qualitative syntheses can be conducted and used to shed light on people's experiences.

This talk was held as part of the Qualitative Research Methods module which is part of the MSc in Evidence-Based Health Care.

The Analogy between States and International Organizations

Series
Public International Law Discussion Group (Part II)
Embed
An analogy between States and international organizations has characterised the development of the law that applies to intergovernmental institutions on the international plane.
That is best illustrated by the work of the International Law Commission on the treaties and responsibility of international organizations, where the Commission for the most part extended to organizations rules that had been originally devised for States. The talk will reflect on the foundations and limits of the assumption that the two main categories of international legal subjects are analogous for certain purposes, and discuss the elusive position that international organizations occupy in the international legal system.

About the speaker:

Fernando Lusa Bordin is a Thornely Fellow and Lecturer in Law at Sidney Sussex College and an Affiliated Lecturer at the University of Cambridge. His research focuses on topics of public international law, including law-making, international organizations and the intersection between international law and legal theory. He holds an LL.B. from the Federal University of Rio Grande do Sul (Brazil), an LL.M. from New York University, and a PhD from the University of Cambridge. He is a recipient of the Yorke Prize (University of Cambridge), Young Scholar Prize (International & Comparative Law Quarterly) and the Diploma of Public International Law (Hague Academy of International Law).

More than meet the eye: Hyperspectral imaging

Series
A Splash of Colour
Embed
How many colours we see is limited by our eye, which contains only three types of colour sensors. Using advanced techniques, vision scientists can take images of this “invisible” information and make it visible.

Neurons code the colour we see

Series
A Splash of Colour
Embed
All activity in your brain – including those which mediates your perception of colour – is based on electrical messages between neurons. Vision scientists can measure these signals at the eye, and at the back of the brain.

In early 2015, an image of a dress polarised the internet: Some people saw it as black-blue, and some as white-gold. Three years on, we revisit the dress and discuss how vision science can explain this phenomenon.

Roger Penrose in conversation with Hannah Fry - Oxford Mathematics Public Lectures

Series
The Secrets of Mathematics
Embed
In our Oxford Mathematics London Public Lecture Roger Penrose in conversation with Hannah Fry reveals his latest research, a veritable chain reaction of universes, which he says has been backed by evidence of events that took place before the Big Bang.
With Conformal Cyclic Cosmology he argues that, instead of a single Big Bang, the universe cycles from one aeon to the next. Each universe leaves subtle imprints on the next when it pops into being. Energy can 'burst through' from one universe to the next, at what he calls ‘Hawking points.’
