Designing gamification for collaborative learning in group work

Computer Supported Collaborative Learning (CSCL) is a teaching and learning approach which is widely adopted. However there are still some problems can be found when CSCL takes place. Studies show that using game-like mechanics can increase motivation, engagement, as well as modelling behaviors of players. Gamification is a rapid growing trend by applying the same mechanics. It refers to use game design elements in non-game contexts. This thesis is about combining gamification concept and computer supported collaborative learning together in software engineering education field. And finally a gamified prototype system is designed.

TYÖILMOITUS TYÖNANTAJALUPAUKSIEN JA TYÖARVOJEN VIESTIJÄNÄ Tarkastelussa menestyneitä Great Place to Work -työnantajia

Työilmoitus voi jäädä työnhakijan ja työnantajan välillä ainoaksi viestinnän mahdollisuudeksi, jolloin ratkaisevaa on, kuinka houkuttelevaksi työnantaja työilmoituksensa laatii kilpaillessaan halutuista osaajista. Samalla työilmoitus antaa lupauksia tulevasta työstä ja työyhteisöstä. Tämän tutkimuksen perimmäinen tarkoitus on tutkia, näkyykö työsuhteen kahdenvälinen transaktioluonne työilmoitusten tasolla eli kerrotaanko ilmoituksissa työnantajan osaajatarpeiden lisäksi, mitkä olisivat työntekijän työllistymisellä saavutetut hyödyt. Tarkemmiksi tarkastelun kohteiksi on valittu kaksi työnhakijan päätöksenteon kannalta mielenkiintoista näkökulmaa: viestityt työarvot ja työnantajalupaukset. Teoreettiselta taustaltaan tämä tutkimus liittyy rekrytoinnin kokonaisuuteen, mutta se sivuaa useita muita aihealueita, kuten yksilön ja yrityksen yhteensopivuutta, työnantajamielikuvaa, psykologista sopimusta, informaation prosessointia, suostuttelua ja työnhakupäätöksen syntymekanismin tutkimusta. Tutkimuksen empiirinen aineisto koostuu kolmena peräkkäisenä vuonna (2013−2015) Suomen parhaimmiksi työnantajiksi tituleerattujen yritysten julkaisemista työilmoituksista. Näiden oletettiin olevan kiinnostuneita työnantajakuvastaan ja rekrytoinnistaan keskimääräistä enemmän. Kerätyistä 19 työilmoituksesta tulkittiin arvoilmaisuja ja annettuja esilupauksia kahden teoreettisen luokituksen yhdistelmänä muodostetun analyysirungon avulla. Aineiston lauseita eriteltiin analyysirungon teemojen alle ja niiden vakuuttamiskeinoja analysoitiin retorisella diskurssianalyysillä. Tutkimuksen tuloksena havaittiin, että työnteon puitteista, palkkatiedoista, määräysvallasta ja työn merkityksellisyydestä mainittiin verrattain vähän työilmoituksissa. Sen sijaan aineiston työilmoituksista löytyi runsaasti ilmaisuja, joista työnhakija voi tehdä päätelmiä työilmapiiristä tai potentiaalisten kollegoiden asiantuntijuuden tasosta. Yrittäjähenkisyys- ja suorituspainepuheiden läpi heijastui puolestaan kovemmat arvot. Arvojen ilmaisu tapahtui usein epäsuorasti kuin selkeinä arvolistoina. Konkreettisia lupauksia työnantajalta työnhakijalle tehtiin vähän tai ne olivat ylimalkaisia. Tutkimus antaa aihetta laajemmille kartoituksille. Mitkä ovat syyt tiettyä kaavaa toistavien työilmoitusten taustalla ja mitkä tekijät työilmoituksissa eri kohdeyleisöjä aidosti vaikuttavat?

Ethical leadership as a way to promote work-related well-being

The purpose of this study was to clarify the connections of ethical leadership with the work-related well-being of employees. Additionally, the role of occupational health care in ethical leadership that promotes work-related well- being was analyzed. The objective of the study was to produce knowledge to support the development of ethical leadership and work-related well-being as well as to find ways for occupational health care to support organizations in these actions. The target groups of this study consisted of the managers (N=43) and employees (N=336) working in one organization in the Finnish energy industry. The population was studied in November 2014 using census. The data was gathered with two different web-based surveys containing structured and open questions. The survey for managers consisted of background questions and statements concerning ethical leadership, work-related well-being and occupational health care. The employee questionnaire consisted of questions about background and statements about work-related well-being and ethical leadership. The structured questions were analyzed with SPSS Statistical Program and the open questions using inductive content analysis. At least 80 % of the managers saw their actions as ethical in all but one part of ethical leadership. The work-related well-being of the employees was found best in the area of ability to work (91 % agreed) and lowest in the area of experience of ethical leadership (67 % agreed). The results showed a strong positive connection between ethical leadership and all the components of work- related well-being. The managers and employees were generally quite happy with the services of occupational health care but managers saw some problems with the collaboration with occupational health care. Several ways to improve work-related well-being and collaboration with occupational health care were found. One of the most important things was thought to be offering ways to maintain ability to work and making these actions visible. Investing in ethical leadership and work-related well-being is extremely important for the success of an organization and the societal benefits cannot be forgotten either. The role of occupational health care in promoting the health and well-being of employees is substantial. Occupational health care should offer managers more tools to recognize difficult situations and acting in them as well as encourage managers to seek help from occupational health care without hesitation in problematic situations of leadership.

The functional fit between collaborative software and work systems:Qualification of work system needs to software functionality

The study develops an approach that tries to validate software functionality to work systems needs in SMEs. The formulated approach is constructed by using a SAAS based software i.e., work collaboration service (WCS), and SMEs as the elements of study. Where the WCS’s functionality is qualified to the collaboration needs that exist in operational and project work within SMEs. For this research constructivist approach and case study method is selected because the nature of the current study requires an in depth study of the work collaboration service as well as a detailed study of the work systems within different enterprises. Four different companies are selected in which fourteen interviews are conducted to gather data pertaining. The work systems method and framework are used as a central part of the approach to collect, analyze and interpret the enterprises work systems model and the underlying collaboration needs on operational and project work. On the other hand, the functional model of the WCS and its functionality is determined from functional model analysis, software testing, documentation and meetings with the service vendor. The enterprise work system model and the WCS model are compared to reveal how work progression differs between the two and make visible unaddressed stages of work progression. The WCS functionality is compared to work systems collaboration needs to ascertain if the service will suffice the needs of the project and operational work under study. The unaddressed needs provide opportunities to improve the functionality of the service for better conformity to the needs of enterprise and work. The results revealed that the functional models actually differed in how operational and project work progressed within the stages. WCS shared similar stages of work progression apart from the stages of identification and acceptance, and progress and completion stages were only partially addressed. Conclusion is that the identified unaddressed needs such as, single point of reference, SLA and OLA inclusion etc., should be implemented or improved within the WCS at appropriate stages of work to gain better compliance of the service to the needs of the enterprise an work itself. The developed approach can hence be used to carry out similar analysis for the conformance of pre-built software functionality to work system needs with SMEs.

Spectral retinal image processing and analysis for ophthalmology

Diabetic retinopathy, age-related macular degeneration and glaucoma are the leading causes of blindness worldwide. Automatic methods for diagnosis exist, but their performance is limited by the quality of the data. Spectral retinal images provide a significantly better representation of the colour information than common grayscale or red-green-blue retinal imaging, having the potential to improve the performance of automatic diagnosis methods. This work studies the image processing techniques required for composing spectral retinal images with accurate reflection spectra, including wavelength channel image registration, spectral and spatial calibration, illumination correction, and the estimation of depth information from image disparities. The composition of a spectral retinal image database of patients with diabetic retinopathy is described. The database includes gold standards for a number of pathologies and retinal structures, marked by two expert ophthalmologists. The diagnostic applications of the reflectance spectra are studied using supervised classifiers for lesion detection. In addition, inversion of a model of light transport is used to estimate histological parameters from the reflectance spectra. Experimental results suggest that the methods for composing, calibrating and postprocessing spectral images presented in this work can be used to improve the quality of the spectral data. The experiments on the direct and indirect use of the data show the diagnostic potential of spectral retinal data over standard retinal images. The use of spectral data could improve automatic and semi-automated diagnostics for the screening of retinal diseases, for the quantitative detection of retinal changes for follow-up, clinically relevant end-points for clinical studies and development of new therapeutic modalities.
