Yhdessä ja liikkeellä. Mobiili sosiaalinen media

Sosiaalinen media viittaa verkkopalveluihin, joiden toiminta perustuu käyttäjien ja käyttäjäyhteisöjen aktiiviseen sosiaaliseen vuorovaikutukseen. Matkapuhelimien kautta sosiaalinen media on liikkeellä ja pitää käyttäjät yhdessä ajasta ja paikasta riippumatta. Sosiaalisen median vetovoima perustuu siihen, että ihmiset jakavat tietoja, kuvia, videota ja ääntä sekä kommentoivat ja jatkavat viestiketjuja. Yhdessä ja liikkeellä -kirja tarkastelee sosiaalisen median uusinta ilmiötä, videoiden jakamista kännykkäpalvelun kautta. Mobiilit videot voivat kertoa jaetuista elämyksistä, konserteista, benji-hypyistä tai jazz-festivaalin vessajonosta. Liikkuva kuva kertoo usein enemmän kuin useampi valokuva, ja monen käyttäjän videokuva samasta tapahtumasta voi jo kertoa monipolvisen tarinan. Yhdessä ja liikkeellä esittelee Mobile Social Media -tutkimushankkeen tuloksia. Tavoitteena on ollut tutkia, millaiset tekijät tukevat mobiilin sosiaalisen median käyttöä ja miten sosiaalista mediaa hyödynnetään matkapuhelimilla, miten sosiaalisen median yhteisö voi muodostaa kännykkävideoista yhteisen tarinan, millaisia teknologisia haasteita mobiilin sosiaalisen median käytölle on. Tutkimushanke on CAT - Culture Art and Technology -verkoston yhteistyötä. Verkostoon kuuluvat Aalto-yliopiston, Tampereen teknillisen yliopiston ja Turun yliopiston Porin yksiköt.

Utilizing social media in software documentation and knowledge management

This Master’s thesis studies the possibilities that social media tools can bring to help knowledge management in software development companies. It will introduce the most popular tools of social media and their usage possibilities in companies, not forgetting the possible downsides. One relevant aspect in this study is to investigate the possibilities of social media to help converting existing tacit knowledge into explicit. The purpose of the work is to create a proposal of social media utilization for a mid-sized software company, which has not utilized social media tools before. To be able to create the proposal, employees of the company are interviewed and a survey is executed to analyze the current situation. In addition a pilot project for trying out new social media tools is executed. The final result of this thesis introduces a tailored solution for the target company to start utilizing social media in its documentation and knowledge sharing processes. This new solution consists of multiple individual suggestions that are categorized and prioritized based on the significance and benefit that they bring to the company.

Physical Realization of an Optical Automatic Target Recognition System

In the modern warfare there is an active development of a new trend connected with a robotic warfare. One of the critical elements of robotics warfare systems is an automatic target recognition system, allowing to recognize objects, based on the data received from sensors. This work considers aspects of optical realization of such a system by means of NIR target scanning at fixed wavelengths. An algorithm was designed, an experimental setup was built and samples of various modern gear and apparel materials were tested. For pattern testing the samples of actively arm engaged armies camouflages were chosen. Tests were performed both in clear atmosphere and in the artificial extremely humid and hot atmosphere to simulate field conditions.

Titrimetric assay of lisinopril in aqueous and non-aqueous media

Four simple titrimetric procedures are described for the determination of lisinopril (LNP) in bulk and in pharmaceuticals based on the neutralization of basic-amino and acidic carboxylic acid groups present in LNP. Method A is based on the neutralization of basic amino groups using perchloric acid as titrant in anhydrous acetic acid medium. Method B, method C and method D are based on neutralization of carboxylic acid group using NaOH, sodium methoxide and methanolic KOH, as titrants, respectively. Method A is applicable over 2.0-20.0 mg range and the calculations are based in the molar ratio of 1:2 (LNP:HClO4). Method B, method C and method D are applicable over 2.0-20.0 mg, 1.0-10.0 mg and 5.0-15.0 mg range, respectively, and their respective molar ratios are 1:1 (LNP:NaOH), 1:2 (LNP:CH3ONa) and 1:1 (LNP:KOH). Intraday and inter day accuracy and precision of the methods were evaluated and the results showed intra- and inter-day precision less than 2.7% (RSD), and accuracy of < 2.5 % (RE). The developed methods were applied to determine LNP in tablets and the results were validated statistically by comparing the results with those of the reference method by applying the Student's t-test and F-test. The accuracy was further ascertained by recovery studies via standard addition technique. No interferences from common tablet exipients was observed.

A pH optode based on thymol blue: application to determination of CO2 using flow injection analysis system

An optode based on thymol blue (TB), an acid-based indicator, has been constructed and evaluated as a detector in FIA system for CO2 determination. The dye was chemically immobilised on the surface of a bifurcated glass optical fibre bundle, using silanisation in organic media. In FIA system, hydrogen carbonate or carbonate samples are injected in a buffer carrier solution, and then are mixed with phosphoric acid solution to generate CO2, which diffuses through a PTFE membrane, in order to be collected in an acceptor carrier fluid, pumped towards to detection cell, in which the optode was adapted. The proposed system presents two linear response ranges, from 1.0 x 10-3 to 1.0 x 10-2 mol l-1, and from 2.0 x 10-2 to 0.10 mol l-1. The sampling frequency was 11 sample h-1, with good repeatability (R.S.D < 4 %, n = 10). In flow conditions the optode lifetime was 170 h. The system was applied in the analysis of commercial mineral water and the results obtained in the hydrogen carbonate determination did not differ significantly from those obtained by potentiometry, at a confidence level of 95 %.

Seriedebatt i 1950-talets Finland : en studie i barndom, media och reglering

I avhandlingen granskas den debatt som fördes om seriemediet och serieläsandet i Finland från början av 1950-talet till början av 1960-talet. Serietidningen var då ett nytt medium och föranledde en oro beträffande barns läsvanor. ”Seriefrågan” diskuterades i pressen och problematiken engagerade barnskyddsorganisationer och forskare, behandlades i riksdagen och undersöktes av en statlig kommitté. De olika debattuttrycken analyseras i studien. Avhandlingens teoretiska perspektiv är styrningsanalytiskt och bygger på diskussionen om regementalitet (governmentality). I studien granskas hur seriemediet, barndom och regleringen av dessa kom att definieras i behandlingen av det s.k. serieproblemet. Serierna definierades som ett problematiskt medium på ett flertal sätt. De huvudsakliga argumenten mot serierna var dels att de förstörde barns läsförmåga, dels att de budskap som serierna förmedlade till barnen var av fel slag. Enligt kritiken var serierna språkligt fattiga och innehållsmässigt alltför våldsamma. Följaktligen utgjorde serierna ett hot mot barnen. Barnen kom ur detta perspektiv att definieras som inkompetenta medieanvändare och i behov av skydd. I debatten upplyftes olika sätt att lösa och reglera problemet. Man undersökte problematiken och upplyste allmänheten om den, man försökte påverka serieutgivarna och man påkallade censur. Seriedebatten och den verksamhet som debattörerna ägnade sig åt ledde dock inte till synbara resultat, t.ex. ny lagstiftning eller förändringar i seriemarknaden. Ändå dog debatten i början av 1960-talet. Problemet med de serieläsande barnen hanterades m.a.o. genom själva debatten. Samtidigt uteblev mera drastiska former av reglering. Ett övergripande syfte för analysen av den kunskap som skapades i debatten – dess varierande förståelse av seriemedium, barndom och reglering – är att erbjuda infallsvinklar till aktuella diskussioner om och farhågor angående barns mediebruk. Med fokus på bredden hos debattens uttryck och de diskursiva ramarna för problematiseringen av barns serieläsande ger avhandlingen perspektiv på den med jämna mellanrum uppdykande frågeställningen om barns mediebruk.

Antimicrobial activity of extracellular metabolites from antagonistic bacteria isolated from potato (Solanum phureja) crops

Microorganisms for biological control are capable of producing active compounds that inhibit the development of phytopathogens, constituting a promising tool toob tain active principles that could replace synthetic pesticides. This study evaluatedtheability of severalpotentialbiocontrol microorganismsto produce active extracellular metabolites. In vitro antagonistic capability of 50 bacterial isolates from rhizospheric soils of "criolla" potato (Solanum phureja) was tested through dual culture in this plant with different plant pathogenic fungi and bacteria. Isolates that showed significantly higher antagonistic activity were fermented in liquid media and crude extracts from the supernatants had their biological activities assessed by optical density techniques. Inhibitory effecton tested pathogens was observed for concentrations between 0.5% and 1% of crude extracts. There was a correlation between the antimicrobial activity of extracts and the use of nutrient-rich media in bacteria fermentation. Using a bioguided method, a peptidic compound, active against Fusarium oxysporum, was obtained from the 7ANT04 strain (Pyrobaculum sp.). Analysis by nuclear magnetic resonance and liquid chromatography coupled to mass detector evidenced an 11-amino acid compound. Bioinformatic software using raw mass data confirmed the presence of a cyclic peptide conformed by 11 mostly non-standard amino acids.

Customer reference marketing and utilization of social media as an integral part of customer references

The objective of this Bachelor's Thesis is to find out the role of social media in the B-to-B marketing environment of the information technology industry and to discover how IT-firms utilize social media as a part of their customer reference marketing. To reach the objectives the concepts of customer reference marketing and social media are determined. Customer reference marketing can be characterized as one of the most practically relevant but academically relatively overlooked ways in which a company can leverage its customers and delivered solutions and use them as references in its marketing activities. We will cover which external and internal functions customer references have, that contribute to the growth and performance of B-to-B firms. We also address the three mechanisms of customer reference marketing which are 'status transfer', 'validation through testimonials' and 'demonstration of experience and prior performance'. The concept of social media stands for social interaction and creation of user-based content which exclusively occurs through Internet. The social media are excellent tools for networking because of the fast and easy access, easy interaction and vast amount of multimedia attributes. The allocation of social media is determined. The case company helps clarify the specific characteristics of social media usage as part of customer-reference-marketing activities. For IT-firms the best channels to utilize social media in their customer reference marketing activities are publishing and distribution services of content and networking services.
