This document summarizes a presentation on online non-participation and negative participation. It discusses current biases in online participation research, including a political bias, positivity bias, and activity bias. It then outlines a qualitative study exploring how citizens define and understand online participation versus engagement. The study finds distinctions between effortful vs. easy, active vs. passive, and positive vs. negative forms of participation. Based on these findings, the presentation proposes a new typology of online participation and non-participation that considers involvement, agency, and social valence.
Social media in politics, digital economy, social business reportNiall Devitt
The impact of Social Media on politics and on democratic participation continues to divide opinion. The following report on the use of social media within politics includes the first comprehensive review of the use of social media by Irish political parties, politicians and government bodies.
The “Social Media in Politics” report looks at how use of Social Media is impacting politicians and political engagement, both here in Ireland and internationally.
It includes:
• The tactics used by President Obama and other world leaders and governments to engage with their peoples on Social Media
• A detailed analysis on use of Social Media by Irish political parties, politicians, state departments and bodies
• Examples and case studies of the positive and negative consequences of democratic participation on Social Media
John Twohig, Managing Partner of The Ahain Group, said “Our analysis indicates that many Irish political parties and their leadership are yet to develop an overarching strategy (or party line) when it comes to their Social Media presence, and, as a result, individual members are more often left to their own devices.”

The strategy of leveraging social media to be in the right place at the right time.
With the astounding impact social media has had on our society, business and individuals are hard at work trying to figure out how to leverage its power. While most can easily see the benefit as a tool for engaging their audience from a digital perch, few companies are leveraging it as a tool to make IRL ( in real life) connections with their audience, customers and/or prospects Tactics such as virtually attending industry events, using twitter hash tags and mentions to facilitate IRL meetings and assessing the power in the room using Foursquare.

Overexposed Portraits: Technology Overload and the Identities of the YoungChristoph Lutz
Technostress and information overload represent serious challenges of the Information Age. An alarming number of people exhibit dangerously intensive media consumption, while Internet and mobile phone addictions are a widespread phenomenon, especially among teens. Despite increasing evidence for technostress and information overload within the literature, the consequences of new media overexposure on young individuals are so far understudied. When it comes to Social Network Sites (SNS), in particular, only limited research has been conducted on the causes and effects of excessive use and perceived overexposure.
The value of social media for identity experimentation, construction and negotiation has been widely covered in research: the aim of our study is to explore how feelings of overexposure and stress relate to the self-expressive needs of teenagers, made explicit through their digital interactions. In this contribution we present and discuss the results of a large-scale survey conducted during an exhibition on media overload in Berne, Switzerland: a total of 6989 adolescents provided answers on their media overload and stress. Through a quantitative analysis, significant factors fostering and inhibiting SNS overload are found. Our results are discussed considering their meanings for the digital identities of teenagers, and for their well-being online.
A Social Milieu Approach to the Online Participation Divides in GermanyChristoph Lutz
This presentation summarizes a qualitative study of participation divides in Germany. Focus groups and online communities with 96 participants from seven distinct social milieus serve to differentiate online participation along social lines. The results show that German citizens are strongly segregated into distinct Internet milieus that differ in their intensity, variety, understanding and attitudes towards online participation. Each milieu displays a specific participatory habitus and some of the findings challenge existing research on digital and participation divides.

Connected for Success: How Network Centrality on ResearchGate Relates to Bibl...Christoph Lutz
Academic social network sites (SNS) are booming. A recent large-scale survey published in Nature indicates that almost 90 percent of researchers in science and engineering and more than 70 percent in the social sciences, arts and humanities are aware of ResearchGate – next to Academia.edu the largest academic SNS with more than 6 million users. However, only limited research has been carried out on academic SNS. Although a vivid community creates and implements alternative measures of scientific impact with social media data, little use has been made of the potential of academic SNS as a data source. Consequently, few studies employ person-based metrics that cover users’ social capital in the form of structural indicators and network statistics (centrality, density, homophily, clustering). This contribution draws on extensive data from ResearchGate to address this issue and add a relational component to altmetrics research. It includes a follower/following network of 302 nodes on ResearchGate: the complete faculty of a Swiss public university who are members on this academic SNS as of early 2014. We describe the overall network with classical metrics of social network analysis and compute the centrality of each individual node. Results indicate low density, high institutional homophily, a skewed degree distribution and many isolates. We then compare the structural properties of individual nodes with other metrics of influence. To do so, the network data is complemented with detailed attribute data, such as department affiliation, gender and position within the university hierarchy. Moreover, we collect researchers’ activity on ResearchGate, bibliometric information, webometrics and altmetrics, i.e., the prominence of their publications on general and specific social media platforms. We evaluate whether the relational aspect of influence in the form network centrality correlates with activity, bibliometric, webometric and almetrics indicators as well as personal attributes. Significant and intermediate correlations between activity and centrality are found, while the correlations between centrality and bibliometric as well as altmetrics are weaker but still significant. No significant correlations between webometrics (coverage of publications on general social media platforms, like Twitter and Facebook) and network centrality occur. The analysis suggests that network centrality is distinct but correlated with (bibliometric) output metrics and therefore worthy of inclusion in future altmetrics studies.

Musikalische Geschmacksbreite und symbolische Grenzziehung im InternetChristoph Lutz
This presentation is a summary of my master thesis. The presentation was on 28 November 2012 in the marvellous and splendid city of Zurich @ University of Zurich.
This presentation emerged from a project at the Digital Methods Summer School at the University of Amsterdam (https://wiki.digitalmethods.net/Dmi/SummerSchool2014). Tommaso Elli, Myrthe Bil, Claudio Coletta, Iris Beerepot, Carlo de Gaetano and I formed the project group. We were interested in the representation of Twitter bots at the World Cup 2014 in Brasil and used different approaches and techniques to detect the bots. It must be said, though, that our approach is largely explorative and cannot provide an exhaustive overview of bot activity at the WorldCupt 2014. Still, some interesting findings emerged that we compiled to this presentation.
This contribution addresses the privacy implications of robots. Two aspects are of fundamental concern in this context: the pervasiveness and intrusiveness of robots on the one hand and a general lack of awareness and knowledge about how robots work, collect and process sensitive data on the other hand.The existing literature on robot ethics provides a suitable framework to address these two issues. In particular, robot ethics are useful to point out how engineers' and regulators' mindset towards privacy protection differs. Different, at first sight incommensurable, rationalities exist between the two when it comes to robotic privacy. As a contribution to the emerging field of robotic privacy, we propose an interdisciplinary and collaborative approach that bridges the two rationalities. This approach considers the role of code as the central governing element of robots. RoboCode-Ethicists, trans-disciplinary experts trained in the technical/computational, legal and social aspects of robotics, should lead the way in the discussion on robotic privacy. They could mediate between different stakeholders and address emerging privacy issues as early as possible.
Beyond Citation Counts - The Potential of Academic Social Network Sites for S...Christoph Lutz
Millions of researchers all around the world have profiles on academic social network sites, such as ResearchGate, Academia.edu, or Mendeley. Still these channels are hardly used for impact assessment. While scientific impact has traditionally been measured with bibliometrics, social media provide new avenues for influence measurement (Altmetrics). We focus on one specific type of social media, namely academic social network sites. How can such platforms provide insights into scientific impact and add to Altmetrics? To answer this question, we rely on a social network analysis of a research community on ResarchGate. The underlying data was provided by the platform provider. It contains detailed interaction and publication information of 55 faculty members of a Swiss public university. We apply a structural perspective and use centrality measures as core indicators of influence within the network.
Our analysis proceeds in three steps: First, we describe the network structure in terms of classical SNA metrics. Second, we analyze whether researchers’ network centrality is associated with other metrics of influence, namely: (a) activity on the platform (b) traditional metrics of scholarly influence (i.e. mainly bibliographic criteria), and (c) academic position. Third, we compare the network structure with that of participants' co-authorship pattern.
Our findings show that activity on the platform is the best predictor of impact within the network, while publication success and academic play less of a role. Implications for research and practice are provided.
Social Media in Science and Altmetrics - New Ways of Measuring Research Impact Christoph Lutz
Social media are becoming more and more popular in scientific communication. Scientists use them for a range of purposes, from sharing publications, to blogging about their own or others’ research, conference tweeting, interpersonal communication and online participation, for example via Q&As on academic social network sites like ResearchGate and academia.edu. Moreover, many social media platforms can be used for impact measurement via so-called altmetrics. Altmetrics capture and aggregate social media metrics such as (re)tweets, Facebook likes, Mendeley bookmarks and Wikipedia cites. They can challenge or at least complement bibliometric impact measures, like the Journal Impact Factor and the h-index, which have been criticized on various grounds. This presentation first summarizes recent studies on social media adoption in science. It then focuses on altmetrics and summarizes key findings in that domain. Finally, it gives a hands-on introduction to altmetrics by demonstrating two prominent services: Impactstory and Altmetric.com.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

“In fact, as several scholars note, one of
the principal problems with the
discourses on participation is that it is
almost always seen as a positive and
empowering force.”
Literat, 2016, p. 10

• Focus groups and online communities

Page 11 General Results
• Clear distinction between participation and engagement;
participation less clearly defined.
• Engagement is seen as more valuable and beneficial than
participation. Engagement is considered social, meaningful and
helpful for others.
• Participation is seen in a very broad sense. Almost every form of
Internet use can be seen as participation:
– Effortful vs. easy forms of participation
– Positive vs. negative forms of participation

“If I just sign up for a service because I want to read something, then I’m a
completely passive participant. But if I sign up and write something
myself, then I’m active.”
“If I only get information on some sites, then I’m not participating. To
participate, you would need to blog, you would have to help others in
online communities, you would need to collect donations in some way or
another. So, you would have to be active in some form. That’s my
understanding of participation.”
“If I am very active on Facebook, then I am participated anew time and
time again by being messaged (…) I am constantly participated for all kind
of nonsense that goes on. I can’t turn that off.”
=> Voluntary and unvoluntary participation can be distinguished

“You get these news about online petitions on your smartphone. And if
that tickles my interest, I might choose to support this petition. And then
you are being kept up-to-date about the petitions you signed.”
“I can participate and I can be participated. Voluntarily or involuntarily.
Participation means actively taking on responsibility. Being participated
means being forced to do something, responsibility being pushed onto
you.”
“Once, I was invited to provide a rating. Finally, after two weeks I managed
to do it, I just wrote two sentences. I was engaged because I had to do
something although I really didn’t feel like doing it.”

“And there are trolls, people who have fun provoking others. And when
they notice that someone pays attention they can spam a whole forum.
It has nothing to do with the original chat anymore.”
“Participation can lead to recruitment in the end. Iraq, Syria and so on…
How many Germans are now fighting for ISIS? They have been recruited
as well.”
“If it’s your thing to dress up in pink bunny costumes and play football
like this, then you can arrange yourself with people from Hong Kong,
London and Barcelona and you meet up in Chile and play. And this is
something I can’t imagine being done by postcard or fan magazine.”
