This paper aims to propose a framework for engaging tourists as citizen scientists in marine research. Justification for such a framework is driven by the increasing use of citizen science (CS) as a method for collecting data in various research projects. While the tenets of CS exist, few studies have demonstrated how these could be integrated to address the challenges and benefits of engaging tourists as scientists.

A systematic review focused on CS-based literature within environmental management, tourism and marine tourism revealed 18 models. Key themes, those repeatedly identified, were extracted. These were adapted to inform the proposed theoretical framework for engaging tourist scientists.

The key themes were clarified and incorporated into the framework to enhance the value of marine research by engaging tourists. Important features considered were the singularity and sporadic nature of tourist participation, training and engagement as well as the reliability of data collected by citizen scientists.

The framework informs the unique requirements of research in marine environments and the under-used potential of tourist scientists.

Resumen

Este artículo propone un marco de trabajo, para involucrar a los turistas como ciudadanos científicos en la investigación marina. La justificación de este marco, está impulsada por el uso creciente de la ciencia ciudadana (CS), como un método para recopilar datos en los proyectos de investigación. Si bien ya existen los principios de la CS, pocos estudios han demostrado cómo estos podrían integrarse para abordar los desafíos y beneficios de involucrar a los turistas como científicos.

Una revisión sistemática, centrada y basada en la literature sobre CS, y al mismo tiempo relacionada con la gestión ambiental, turismo y turismo marino, reveló 18 diferentes modelos. Se extrajeron los temas clave, identificados repetidamente. Estos fueron adaptados para fundamentar el marco teórico propuesto e involucrar a los científicos turísticos.

Se aclararon los temas claves y se incorporaron en el marco de trabajo, para aumentar el valor de la investigación marina, mediante la participación de los turistas. Las características consideradas importantes, fueron la singularidad y la naturaleza esporádica de la participación turística, la capacitación y el compromiso, así como la fiabilidad de los datos recopilados por los científicos ciudadanos.

El marco de análisis, expone los requisitos únicos de investigación en entornos marinos y el potencial infrautilizado de los científicos turísticos.

Bacterial exopolysaccharides (eps) have fascinating chemical compositions, properties and structures which could be used in the modification of natural fibres. Bacterial eps have therefore been used to modify plant cellulose fibre surface and impart desired properties. The purpose of this paper is therefore to investigate the influence of gin trash cultured bacteria eps on the physical and structural properties of cotton fibres.

Gin trash soil sample was collected from a ginnery in Kenya, and physiochemical and microbial characterization was done. The soil sample was then fermented for 24 h before being used to treat raw cotton fibres at varied conditions of temperature, pH and treatment time periods. Physical and structural properties of the treated fibres were then determined using USTER HVI-1000 M700, Fourier transform infrared, scanning electron microscope (SEM) and X-ray diffraction (XRD) and compared with those of the raw fibres.

The bacteria broth treated fibres were found to have increased in strength, spinning consistency index, elongation and fineness by 25.44, 24.30, 11.70 and 3.60%, respectively. The variations were attributed to interactions of bacterial eps with cotton cellulose through hydrogen bonding. SEM and XRD analysis revealed an increase in fibre surface roughness and crystallinity, respectively.

Bacterial eps have been used to modify plant cellulose fibre surface and impart desired properties. Eps producing bacteria have been isolated from different habitats such as saline water, soil samples, food wastes and petroleum-contaminated soil. To the best of the authors’ knowledge, bacterial eps cultured from gin trash soil sample for modification of cotton fibres have however not been previously done, hence the originality of the current study.

The purpose of this paper is to investigate how non-research users access and use digital surrogates from archival collections via mobile walking tour app. Much of the existing literature that discusses outreach for digitised archival collections in libraries, archives and museums (LAMs) reports examples of single outreach events or discusses outreach broadly, without critically exploring the purpose and context of outreach as an activity. Further, these reports generally aim to introduce collections to potential researchers, amateur or professional, without consideration of how the collections could be used for purposes other than research, by non-researchers. The study aims to expand understanding of non-research use of digital surrogates contextualised by mobile technology.

Utilising an exploratory approach, Walk1916, a mobile walking tour app of Easter Rising sites in Dublin was first developed. It contextualised digital surrogates from archival collections, along with an audio and a textual description of the image, with augmented reality (AR) and geolocation technology. In all, 15 semi-structured interviews were then conducted to understand how contextualising digital surrogates with these mobile technology features influenced participants’ perceptions of the digital surrogate. Interview transcripts were transcribed and analysed via memoing and coding, using nVivo for Mac 10.2.2.

Findings from interview data suggest that contextualising the digital surrogate with AR and geolocation features allowed participants to perceive of the digital surrogate as enhancing their understanding of the Easter Rising, enhancing life and allowing for increased control of their experience.

This furthers work in the area of how individuals value digital surrogates, in different (non-research) contexts. These findings provide groundwork for the future study of non-research access to and use of digital surrogates held in institutional collections so that LAMs can utilise collections efficiently for a wider user base.

The purpose of this paper is to examine intrinsic forms of motivation and particular incidents of play, socialisation, fun and amusement on an online crowdsourced citizen science platform. The paper also investigates gamised activity (Greenhill et al., 2014) as a form of intrinsic motivation adding a sense of play to work and tasks (Xu et al., 2012). These concepts are explored through close scrutiny of the online citizen science platform Zooniverse.org.

Qualitative techniques with an interpretivist approach are used to analyse online content found within citizen science platforms, related forums and social media by examining incidents of play, socialisation, fun and amusement to investigate how these aspects are applied as a form of user motivation.

The authors find that when users classify crowdsourced tasks voluntarily it does not matter how users are classifying as long as it is accurately. However, what does matter is why they are doing it particularly because of the complex processes that builds relationships between users and the platform. The authors present a conceptual model to enable deeper understandings of how forms of social interaction and play are motivating users contributing to citizen science project to participate in the online processes.

The findings of this paper provide practical implications for how citizen science, and also other crowdsourcing platforms, can engage with notions of play and gamification to motivate participation.

Using detailed examples of online content, the authors reveal how participants of the Zooniverse.org demonstrate aspects of “gamised” behaviour. The authors argue that the exploration of gaming as well as play provides evidence that contributing to citizen science projects can be both utilitarian and hedonic.

The importance of radiation curing was emphasised in the United States in 1984 when over 11,000 people specialising in this area — either a manufacturer or user attended a conference on the subject. Obviously interest is high.

The time of the meaningless bit of paper had come and gone and, with a murderous dictator on the rampage, the great Churchill was called upon to truck with another unsavoury character in the east and pledge national assets for more democratic help via the New World. In anticipation of a further reckoning with Germany, trade generally had begun to pick up by 1932 and the paint industry received commensurate benefit. Rearmament took up any slack and one assumes brought to an end the deterioration in turnover of such companies as Nobel Chemical Finishes. Indeed, the general atmosphere in paint company boardrooms was one of smiles tempered with a certain anxiety regarding the international situation. Then, the inevitable happened, and the whole degrading business of war had to be re‐enacted in the broader interest of stifling tyranny.
