Patterns-based Information Systems Organization
Sergej Lugović, Ivan Dunđer, Marko Horvat
Summary
The socio-technical systems research paradigm is about the complexity of real situations. It confronts us with the quest for variables that could provide us with insight into the behavior of such systems. Their behavior emerges according to internal system properties and adaptation of the system to external conditions.
In our view, behavioral patterns are one of those particular variables since machines can recognize them and their dynamics. Based on the synthesis of three different theoretical frameworks, this paper proposes a concept of patterns-based information system organization. The authors built the concept on the Deacon discussion of theory of information, Hofkirchner’s unified information theory and related system behavior, and Kelso’s explanation of pattern creation processes in self-organizing systems. All three researchers have included patterns in their theoretical proposal. According to this analysis of the existing theories and their synthesis, we conclude that in order to design machines that can automatically support new behavior, we have to analyze humans and machines as a complex whole with dynamic relationships and emerging patterns as a dependent variable of behavior. By developing this theoretical concept, we establish a departure point for future research and search for different variables that correlate with pattern formation.

This document discusses five common sins of nonprofit marketing and how social media can help address them. It begins by explaining why nonprofit marketing matters to attract donors, members and volunteers. It then outlines five sins of nonprofit marketing: 1) Marketing not grounded in research of audiences. 2) Ignoring basic marketing principles. 3) Communications not focused on consumers. 4) Undervaluing content development. 5) Treating marketing as a cost rather than investment. The document then discusses why social media is important given changes in information delivery and consumer behaviors. It provides examples of how some nonprofits have benefited from social media. In the end, it stresses the importance of measuring results and having a strategic marketing approach.
Twitter is one of the biggest microblogging platforms that millions of Tweets of maximum size 140 characters are posted every day by its users. Recently many research efforts have been presented towards analyzing the content of information in Twitter for marketing purposes. However, existing analysis
approaches have shortcomings in terms of exploiting this media to improve marketing policy in a University. Thus, efficient analyzing technique is a pressing need to complement the existing approaches and hence improve the performance of marketing department in a university through getting public mood from Twitter and apply a number of analysis. To this end, in this paper, we develop a desktop based application that can help marketing staff in Heriot-Watt University to analyse Tweets related to the university and can help in course marketing. The application enables users to retrieve Tweets from Twitter corpus which are related to the university. Afterwards, users will be able to perform a number analysis on
the retrieved Tweets such as Word Frequency Analysis, User Frequency Analysis and Sentiment Analysis. Finally, users of the application will be able to export the results in to a spreadsheet. After the application is evaluated, most of the participants agreed that it is reliable and easy to use and that the application has a good performance and can be used for marketing purposes.

Q4 public company use of social media for investor relations summer2010weichengwendao
This document analyzes the use of social media by 362 public companies for investor relations purposes. It finds that the majority (65%) use Twitter, followed by Facebook (37%), YouTube (29%), blogs (10%) and SlideShare (10%). Technology companies make greatest use of social media for investor relations across all platforms. The US leads in social media adoption for investor relations, followed by Europe. Large cap companies generally use social media more than small and mid cap companies for investor relations. While LinkedIn is not currently used directly for investor relations, it is an important professional network for financial services professionals to follow. The study provides best practices for using different social media and concludes that social media use for investor relations continues to grow.

- The document discusses applying data mining techniques like correlation, clustering, and association analysis to social media data, specifically tweets mentioning Allstate.
- Over 68,000 tweets were analyzed from over 40,000 unique users between August 2010-August 2011. The number of tweets increased significantly from March-May 2011 before decreasing.
- Data mining can help insurance companies systematically analyze valuable information from social media investments to better understand customers and issues in the marketplace.
LinkedIn - Institutional Investing in the 21st CenturyJonathan Kay
Nearly three-quarters of institutional investors in Europe use social media like LinkedIn for financial information and investing decisions. LinkedIn is the most popular and trusted social platform, used by over 40% of investors. After consuming information on social media, many investors take action like further research, choosing to work with particular companies, making investment recommendations or decisions. Institutional investors turn to LinkedIn especially for in-depth subject matter education and researching asset management firms. They are 4 times more likely to use LinkedIn over other social platforms for these purposes.
For our NGOs and International Organizations to not only survive but thrive, we need to change the way we are funded and improve the way we work. We need to manage our organizations better, be more agile, and need to diversify funding to make them more robust.
In this webinar, we reflect on 10 years of transforming non-profits into agile and better-funded changemakers. We identify five essential attributes that have made some MzN partners successful and thrive through times of crisis. We look ahead to see what leaders can do now to create organizations that deliver profound impact and advance in a disrupted world.
This document summarizes a presentation about how NGOs need to become more agile and robustly funded to survive ongoing disruptions. It discusses that NGOs must be able to respond and adapt more quickly given accelerating changes like COVID-19, digitalization, and a looming recession. To do so, NGOs need to move away from static structures organized around donor demands and toward more flexible, learning-focused models using data and collaboration. Examples are given of NGOs that diversified funding and prioritized data to gain strategic opportunities. The presentation argues that NGOs must have the courage to change aspects within their control to ensure the right funding, structures, and mindsets for future impact.
The document discusses social media strategies for foundations. It provides examples of foundations at different levels of social media maturity from crawl to fly. The Centre Foundation example shows a small foundation using a multi-channel social media strategy to increase awareness, raise funds during a Giving Day, and inspire first-time donations. The strategy includes training local nonprofits and an integrated outreach campaign using social media.
The document discusses a case study of the Fuel What Matters clean energy outreach campaign. Analytics were used to (1) update contact lists which improved newsletter open rates, (2) focus Twitter outreach as social media was most successful, and (3) inform future improvements when the campaign is rebooted. Google Analytics tracked website usage, newsletter analytics monitored email performance, and Twitter analytics assessed hashtag engagement to optimize outreach.
This document summarizes a presentation about using social media for law firms. It discusses how social media can help build a firm's public reputation and support business development efforts. It explores common social media platforms like LinkedIn, blogs, and Twitter and how they are growing significantly in use. The presentation aims to dispel myths that social media is just a fad, only for younger users, or that clients and competitors are not using it. It provides data showing social media use is widespread across age groups and that clients and law firms widely use platforms like LinkedIn, blogs and Twitter.

Water resources and food production have been interconnected since early civilizations. Areas with low population densities and less dependence on agriculture are less likely to experience water-related issues. However, rural communities with over 50% of their population in rural areas and over 30% of GDP from agriculture that are also experiencing increasing population and climate change impacts on water availability are likely to face water issues. International cooperation over shared river basins can have multiplier benefits like lower costs, increased benefits, and opportunities for cooperation beyond water management.
We are a young company from Croatia that thrive on the digital transformation of the agro-food industry and strive for the removing barriers between farmers and urban population making the world more sustainable, so;
-our children could enjoy their life better,
-preserve nature and
-making food production easy.

Aim of this paper is to present results from the EU Knowledge Transfer Study 2010-2012 and put them in the context of the Knowledge Spillover Theory of Entrepreneurship (KSTE).
Findings are based on the questionnaire send to the Public Research Organisations (PRO) in 28 EU Member States and survey has to be fulfilled by the recommendation requirement that Member States should “inform the Commission by 15 July 2010 and every two years thereafter of measures taken on the basis of this Recommendation, as well as their impact”.
Technology Entrepreneurship - Short introductory courseSergej Lugovic
The document outlines several key themes in the technology entrepreneurship literature, including identifying the factors that influence technology firm formation, the consequences of technology entrepreneurship on socio-economic development, processes that occur within small tech firms, and the interdependence between small firms and external infrastructure. It notes that the field has focused more on small firms than larger ones and has not substantially contributed to other fields like economics or management. Definitions of technology entrepreneurship include the organization, management, and risk bearing of a technology-based business.
Twitter and Teaching: to Tweet or not to Tweet?Sergej Lugovic
As increasingly more new skills are necessary for graduates entering the workplace or seeking employment, business leaders, politicians and educators suggest that if students are to succeed in today's world, they will require 21st century skills. However, there is no single agreed-upon set of skills. We argue that social media skills are becoming ever more important for employment and society should class them as important 21st-century skills from maintaining well-rounded social media profiles to more advanced data science and analytic skills. At the same time, such a demand affects the teaching process since teachers have to acquire new knowledge about the available tools. Twitter as a microblogging platform is definitely one of the tools that is a part of 21st-century social skills. Thus, by integrating it into the teaching process, Twitter can generate new experiences for both sides, the students and the teachers. In this paper, we conduct a descriptive review of the recent literature that covers Twitter use in teaching. We reviewed results from the top 100 retrieved research results in Web of Science on Twitter and teaching in the domains of social science, science technology, and arts and humanities. We analysed the results quantitatively in terms of content, methods, and methodologies and qualitatively as the description of results found in selected papers that meet certain criteria. This paper also discusses different research departure points for use in further research of the topic.

Lugović, S., & Špiranec, S. (2013).
ABSTRACT Whereas at one time the decisive factor of production was the land, and later capital – today the decisive factor is increasingly man himself, that is, his knowledge. Pope John Paul II (1991). Centesimus Annus Summary The question this paper addresses is whether more variety in meaning of capital could increase the value of capital as one of the factors of production. Methodology used is based on observation, and in this stage of research of this phenomenon we believe that detailed observations are needed with aim to provide enough qualitative data for further development of qualitative methods. Based on a case study from the music industry, the authors have tried to determine whether the extensive use of technology, relationship, knowledge and emotions can be used as a resource for value production in today's economy? These four factors, under complex system analyses of their relationship, could provide enough variety to respond to increasing variety (diversity) developed in music industry environment. In the first part of the paper the on-going rise of importance of intangible values and their relationship with tangible one is discussed. After that, value theories are observed and their relationship to information science is being examined. In the last section, the authors will assert that increasing complexity, coupled (combined/conjoined) with faster changes in the music industry should directly be related to the development of new factors of production used to generate value which can be exchanged on the market. The proposed changes will be tested on a case study.

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.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
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).

ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptxRASHMI M G
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skills
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

2. Twitter usage for the purpose of
entrepreneurial activities
• marketing activities
• medium of communication
• support the whole process from opportunity recognition
to bringing those opportunities to life
• global reach and low cost
• support promotion and branding since
• community interactions
• observe the competition and industry
• better understanding and engaging with customers
(including customer support)
• a tool integrated into product development, marketing
communication, and recruitment
3. Social Media Platforms
• 316 million monthly active users and than 500
million tweets per day
• 93 percent declare that they employ social
media in their marketing strategy,
• Facebook is top-rated (92%), followed by
Twitter (84%) and LinkedIn (71%)
• there’s a statistically significant relationship
between a firm’s innovativeness and the
adoption of Twitter - Wamba & Carter
(2013),
4. Investor Relations
IR is a strategic management responsibility that’s
integrated into
finance,
communication,
marketing, and
law compliance
to enable two-way communications between company,
the financial community, and other stakeholders
It contributes to a company’s security to achieve fair
valuation
5. Investor Relations
• investors match the take-up on social media by companies, and
social media has the potential to move financial markets
• 63 percent of finance professionals (including brokers and heads
of trading desks) believe that valuation of individual stocks can
directly link to public sentiment contained in social media
channels
• 63 percent of 800 publicly traded companies use Twitter for
investor-related activities
• three out of five financial bloggers use Twitter as their primary
news source
• Twitter is the most widely used channel for IR, 72 percent out of
890 companies surveyed used Twitter to communicate
investment materials in 2013
• investors viewed financial blogs, along with LinkedIn and
Twitter, as the most valuable social media resources
6. “startup” as a phenomenon
• Venture capital funds in the EU
• mentioned frequently within the media,
within political speeches, and European
commission programs
• there’s still no clear definition
of what a startup is
7. Two Side of the Coin
• Ewing Marion Kauffman Foundation (Morelix et al.,
2015) stating that “Startup businesses here are
defined as employer firms less than one year old
employing at least one person besides the owner.”
• definition by NESTA (Dee at al., 2015) that defines
startups as “[A] young, innovative, growth–oriented
business (employees/revenue/customers) in search of
a sustainable and scalable business model.”
• NESTA, the emphasis is on defining startups as young companies. They
differ from overall SMEs and need to develop different policies to support
young companies and different ones to support small firms.
8. research into entrepreneurial behavior
• there’s no consensus on what a startup is and
what it does.
• Instead of seeking a definition, it’s necessary to
look at what those companies are doing
• not “What is this?” but instead, “What does it
do?”
• It doesn’t consider objects; rather, it considers
the ways of behaving (Ashby, 1957).
• companies actually do is the result of their
founders’ action.
9. This paper examines the correlation of the
Twitter usage of startup founders across the EU
with the total country investment in startups in
order to ascertain the extent to which we can
predict how the startups will behave in the
future.
10. Methodology
• In total, the authors retrieved 50,433 founders from 29 EU countries (including
Norway), with the assistance of four freelance workers hired through the
Upwork platform (Upwork.com, n.d.) from F6S.com, which has more than
110,000 companies in the database and 2 million unique visitors a month
(f6s.com, 2015)
• There were more records in total; however, some founders related to more
than one company, so the data set had to be de-duped (i.e., the removal of
duplicates).
• Registering founders had the option to submit a company Twitter account and
personal Twitter account. For the purpose of this research, the authors focused
on the personal Twitter accounts the founders submitted.
• After the identifying the Twitter accounts, the authors retrieved data from the
accounts, in particular, the date the founders joined Twitter, how many tweets
they posted, how many accounts they were following, and how many followers
they had, in total 15,192 accounts.
• We also classified whether an account was private for the purpose of this
study, and this was inferred from whether the founder submitted it as a private
Twitter account.
• The authors retrieved data from twenty-nine countries from the EU, including
Norway.
11. Methodology
• In parallel, the analytical company Funderbeam (2015) provided
the financial data addressing EU-wide startup investments.
• This financial data broke down into investment per capital per
country and total amount of investment in the startup
ecosystem per particular country.
• Further, we selected Twitter accounts that had more than one
hundred tweets and then more than one hundred followers.
• Those accounts, when filtered, were entered into the retrieval
system Twitter Arching Google Sheets (TAGS) (Hawksey, 2013),
which the researchers set to retrieve data on daily basis from
those accounts.
• In total, there are 9,696 startup founders that have more than
one hundred tweets and more than one hundred followers, and
the accounts went into the TAGS system. The data retrieval
period was from July 15, 2015 to ...
12. Hypotheses
• H1 time spent on Twitter
• H2 number of tweets of total country startup founders
• H3 number of followers of total country startup founders
• H4 Number of startup founders with more than one
hundred tweets and followers per country
• H5 Percentage of total number of startup founders in the
F6S.com database
• will be a statistically significant positive correlation with
• a) total investment in that country and
• b) investment per capita.
13.
14. DISCUSSION
• Rejection of other hypotheses could be
interpreted that the average quantity of the
tweets, followers, those the founders followed,
and period spent on Twitter per country do not
have an impact on the size of the investment
startups receive and distribution of investment
per capita.
• Therefore, it isn’t about how much is tweeted,
however it could relate to the country level of
Twitteracy (Greenhow & Gleason, 2012).
15. • Bernstein, Korteweg, & Laws (2015) showed that average
investors when looking for information about startups
strongly respond to the founding team but not to firm
traction or lead investors.
• (Tata et al., 2015) used data from Twitter accounts of startup
founders and analyzed the content of their tweets in relation
to funding raised
• They found relations between tweets content and startup
performance, including funding raised.
• The results demonstrate that high past focus, low future
focus, high collective self-categorization, and lower level
construals can associate with better performance.
• Findings from this research, in particular, collective self-
categorization, align with our findings, showing that size of
the country ecosystem of startup founders is in positive
correlation with country investment
16. • The stronger the country’s Twitter community is
the more the country receives in funding
• Lack of significant correlation between number
of tweets, followers/following, and days spent
on Twitter lead the authors to question
relevance of the content created and
distributed over Twitter to the investors.
• The hypotheses presented in this paper are put
forward on a macro level (correlating within EU
countries), and a micro level (individual
founders’ accounts) analysis has to be explored
and analyzed in the next phase of the research
17. Future Research
• dynamics of the founders’ Twitter activities could correlate with
startup performance
• sentiment analysis, network analysis, and the correlation of
Twitter data with the companies’ income.
• correlation with Twitter data with another social media
channel, for example, Facebook or LinkedIn, or data such as the
companies’ Wikipedia pages and the number of visitors to the
websites of the startups.
• use a variety of databases; however, this may not be feasible
since the numbers gathered could become difficult to manage
• the research continues to collect data on a continuing basis
from the 9,696 startup founders (Twitter accounts), which could
provide insight into different aspects of startup as a
phenomenon.
18. CONCLUSION
• The findings demonstrate that it’s possible to
achieve great insight into the behavior of an
object of interest by using indirect
observation, in this instance observing Twitter
data indirectly.
• However, to do so, the analysis has to dig
deeper into the large amount of unstructured
data processed by using advanced techniques.
