Online newspaper framing of non-communicable diseases : comparison of mainland China, Taiwan, Hong Kong and Macao

Chang, Angela ; Schulz, Peter J. ; Cheong, Angus Wenghin

In: International journal of environmental research and public health, 2020, vol. 17, no. 15, p. 15 p

As non-communicable diseases (NCDs) are now well recognized as the leading cause of mortality among adult populations worldwide, they are also increasingly the focus of media coverage. As such, the objective of this study is to describe the framing of NCDs in the coverage of newspapers, with the understanding that it says something about the society producing it. Automatic content analysis was ...

Online patient education and risk assessment : project OPERA from cancerbackup - putting inherited breast cancer risk information into context using argumentation theory

Mackay, James ; Schulz, J. Peter ; Rubinelli, Sara ; Pithers, Andrea

In: Patient education and counseling, 2007, vol. 67, no. 3, p. 261-266

Many people are concerned about their family history of breast cancer, and are anxious about the possibility of developing breast cancer themselves. The majority of these people are likely not to be at significantly increased risk of developing inherited breast cancer. All women are at risk of developing sporadic breast cancer, and this risk increases with age. The UK National Institute of Health...

The ontology of conflict

Greco Morasso, Sara

In: Pragmatics & cognition, 2008, vol. 16, no. 3, p. 540-567

This paper aims at clarifying the ontology of conflict as a preliminary for constructing a conflict mapping guide (Wehr 1979). After recalling the main definitions elaborated in different disciplines, the meaning of conflict is elicited through semantic analysis based on corpus evidence. Two fundamental meanings emerge: conflict as an interpersonal hostility between two or more human subjects,...

Opening study on the development of a new biosensor for metal toxicity based on pseudomonas fluorescens pyoverdine

Chiadò, Alessandro ; Varani, Luca ; Bosco, Francesco ; Marmo, Luca

In: Biosensors, 2013, vol. 3, no. 4, p. 385-399

To date, different kinds of biosensing elements have been used effectively for environmental monitoring. Microbial cells seem to be well-suited for this task: they are cheap, adaptable to variable field conditions and give a measurable response to a broad number of chemicals. Among different pollutants, heavy metals are still a major problem for the environment. A reasonable starting point...

An operational approach to norms in artificial institutions

Viganò, Francesco ; Fornara, Nicoletta ; Colombetti, Marco

The notion of artificial institution is crucial for the specification of open and dynamic interaction frameworks where heterogeneous and autonomous agents can interact to face problems in various fields, like for instance electronic commerce, business-to-business (B2B) applications, and personal assistant applications. In our view the specification of artificial institutions requires a clear...

Optimal atomic broadcast and multicast algorithms for wide area networks

Schiper, Nicolas ; Pedone, Fernando

In this paper, we study the atomic broadcast and multicast problems, two fundamental abstractions for building fault-tolerant systems. As opposed to atomic broadcast, atomic multicast allows messages to be addressed to a subset of the processes in the system, each message possibly being multicast to a different subset. We require atomic multicast algorithms to be genuine, i.e., only processes...

Optimal conditionally unbiased bounded-influence inference in dynamic location and scale models

Mancini, Loriano ; Ronchetti, Elvezio ; Trojani, Fabio

In: Journal of the American Statistical Association, 2005, vol. 100, no. 470, p. 628-641

This paper studies the local robustness of estimators and tests for the conditional location and scale parameters in a strictly stationary time series model. We first derive optimal bounded-influence estimators for such settings under a conditionally Gaussian reference model. Based on these results, optimal bounded-influence versions of the classical likelihood-based tests for parametric...

Optimal decision-making with time diversification

Vanini, Paolo ; Vignola, Luigi

In: European Finance Review, 2002, vol. 6, p. 1-30

One of the most enduring topics in financial theory is the persistence of investment risk across time. Traditional finance lacks methods for considering and hedging non-diversifiable risks. This paper is based on the general equilibrium model of Allen and Gale (1997). We extend their model in various directions: the intermediary is a firm and not a planner, financial markets are assumed to be...
