    Geomemories - A Platform for Visualizing Historical, Environmental and Geospatial Changes of the Italian Landscape2013In: ISPRS International Journal of Geo-Information. Special issue: Geospatial Monitoring and Modelling of Environmental Change, ISSN 2220-9964, Vol. 2, no 2, p. 432-455Article in journal (Refereed)
    Abstract [en]

    The GeoMemories project aims at publishing on the Web and digitally preserving historical aerial photographs that are currently stored in physical form within the archives of the Aerofototeca Nazionale in Rome. We describe a system, available at http://www.geomemories.org, that lets users visualize the evolution of the Italian landscape throughout the last century. The Web portal allows comparison of recent satellite imagery with several layers of historical maps, obtained from the aerial photos through a complex workflow that merges them together. We present several case studies carried out in collaboration with geologists, historians and archaeologists, that illustrate the great potential of our system in different research fields. Experiments and advances in image processing technologies are envisaged as a key factor in solving the inherent issue of vast amounts of manual work, from georeferencing to mosaicking to analysis.

    Methods for 2D and 3D Quantitative Microscopy of Biological Samples2011Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    New microscopy techniques are continuously developed, resulting in more rapid acquisition of large amounts of data. Manual analysis of such data is extremely time-consuming and many features are difficult to quantify without the aid of a computer. But with automated image analysis biologists can extract quantitative measurements and increases throughput significantly, which becomes particularly important in high-throughput screening (HTS). This thesis addresses automation of traditional analysis of cell data as well as automation of both image capture and analysis in zebrafish high-throughput screening. 

    It is common in microscopy images to stain the nuclei in the cells, and to label the DNA and proteins in different ways. Padlock-probing and proximity ligation are highly specific detection methods that  produce point-like signals within the cells. Accurate signal detection and segmentation is often a key step in analysis of these types of images. Cells in a sample will always show some degree of variation in DNA and protein expression and to quantify these variations each cell has to be analyzed individually. This thesis presents development and evaluation of single cell analysis on a range of different types of image data. In addition, we present a novel method for signal detection in three dimensions. 

    HTS systems often use a combination of microscopy and image analysis to analyze cell-based samples. However, many diseases and biological pathways can be better studied in whole animals, particularly those that involve organ systems and multi-cellular interactions. The zebrafish is a widely-used vertebrate model of human organ function and development. Our collaborators have developed a high-throughput platform for cellular-resolution in vivo chemical and genetic screens on zebrafish larvae. This thesis presents improvements to the system, including accurate positioning of the fish which incorporates methods for detecting regions of interest, making the system fully automatic. Furthermore, the thesis describes a novel high-throughput tomography system for screening live zebrafish in both fluorescence and bright field microscopy. This 3D imaging approach combined with automatic quantification of morphological changes enables previously intractable high-throughput screening of vertebrate model organisms.

    Abstract [en]

    Detection and localization of fluorescent signals in relation to other subcellular structures is an important task in various biological studies. Many methods for analysis of fluorescence microscopy image data are limited to 2D. As cells are in fact 3D structures, there is a growing need for robust methods for analysis of 3D data. This article presents an approach for detecting point-like fluorescent signals and analyzing their subnuclear position. Cell nuclei are delineated using marker-controlled (seeded) 3D watershed segmentation. User-defined object and background seeds are given as input, and gradient information defines merging and splitting criteria. Point-like signals are detected using a modified stable wave detector and localized in relation to the nuclear membrane using distance shells. The method was applied to a set of biological data studying the localization of Smad2-Smad4 protein complexes in relation to the nuclear membrane. Smad complexes appear as early as 1 min after stimulation while the highest signal concentration is observed 45 min after stimulation, followed by a concentration decrease. The robust 3D signal detection and concentration measures obtained using the proposed method agree with previous observations while also revealing new information regarding the complex formation.

    Abstract [en]

    Segregation of mitochondrial DNA (mtDNA) is an important underlying pathogenic factor in mtDNA mutation accumulation in mitochondrial diseases and aging, but the molecular mechanisms of mtDNA segregation are elusive. Lack of high-throughput single-cell mutation load assays lies at the root of the paucity of studies in which, at the single-cell level, mitotic mtDNA segregation patterns have been analyzed. Here we describe development of a novel fluorescence-based, non-gel PCR restriction fragment length polymorphism method for single-cell A3243G mtDNA mutation load measurement. Results correlated very well with a quantitative in situ Padlock/rolling circle amplification–based genotyping method. In view of the throughput and accuracy of both methods for single-cell A3243G mtDNA mutation load determination, we conclude that they are well suited for segregation analysis.

    Abstract [en]

    Images can be acquired at high rates with modern fluorescence microscopy hardware, giving rise to a demand for high-speed analysis of image data. Digital image cytometry, i.e., automated measurements and extraction of quantitative data from images of cells, provides valuable information for many types of biomedical analysis. There exists a number of different image analysis software packages that can be programmed to perform a wide array of useful measurements. However, the multi-application capability often compromises the simplicity of the tool. Also, the gain in speed of analysis is often compromised by time spent learning complicated software. We provide a free software called BlobFinder that is intended for a limited type of application, making it easy to use, easy to learn and optimized for its particular task. BlobFinder can perform batch processing of image data and quantify as well as localize cells and point like source signals in fluorescence microscopy images, e.g., from FISH, in situ PLA and padlock probing, in a fast and easy way.

    Abstract [en]

    Robust detection and localization of biomolecules inside cells is of great importance to better understand the functions related to them. Fluorescence microscopy and specific staining methods make biomolecules appear as point-like signals on image data, often acquired in 3D. Visual detection of such point-like signals can be time consuming and problematic if the 3D images are large, containing many, sometimes overlapping, signals. This sets a demand for robust automated methods for accurate detection of signals in 3D fluorescence microscopy. We propose a new 3D point-source signal detection method that is based on Fourier series. The method consists of two parts, a detector, which is a cosine filter to enhance the point-like signals, and a verifier, which is a sine filter to validate the result from the detector. Compared to conventional methods, our method shows better robustness to noise and good ability to resolve signals that are spatially close. Tests on image data show that the method has equivalent accuracy in signal detection in comparison to Visual detection by experts. The proposed method can be used as an efficient point-like signal detection tool for various types of biological 3D image data.

    Abstract [en]

    The zebrafish larva is an optically-transparent vertebrate model with complex organs that is widelyused to study genetics, developmental biology, and to model various human diseases. In this article, wepresent a set of novel technologies that significantly increase the throughput and capabilities of ourpreviously described vertebrate automated screening technology (VAST). We developed a robustmulti-thread system that can simultaneously process multiple animals. System throughput is limitedonly by the image acquisition speed rather than by the fluidic or mechanical processes. We developedimage recognition algorithms that fully automate manipulation of animals, including orienting andpositioning regions of interest within the microscope’s field of view. We also identified the optimalcapillary materials for high-resolution, distortion-free, low-background imaging of zebrafish larvae.

    Abstract [en]

    Cell cultures as well as cells in tissue always display a certain degree of variability,and measurements based on cell averages will miss important information contained in a heterogeneous population. These differences among cells in a population may be essential to quantify when looking at, e.g., protein expression and mutations in tumor cells which often show high degree of heterogeneity.

    Single nucleotide mutations in the mithochondrial DNA (mtDNA) can accumulate and later be present in large proportions of the mithocondria causing devastating diseases. To study mtDNA accumulation and segregation one needs to measure the amount of mtDNA mutations in each cell in multiple serial cell culture passages. The different degrees of mutation in a cell culture can be quantified by making measurements on individual cells as an alternative to looking at an average of a population. Fluorescence microscopy in combination with automated digital image analysis provides an efficient approach to this type of single cell analysis.

    Image analysis software for these types of applications are often complicated and not easy to use for persons lacking extensive knowledge in image analysis, e.g., laboratory personnel. This paper presents a user friendly implementation of an automated method for image based measurements of mtDNA mutations in individual cells detected with padlock probes and rolling-circle amplification (RCA). The mitochondria are present in the cell’s cytoplasm, and here each cytoplasm has to be delineated without the presence of a cytoplasmic stain. Three different methods for segmentation of cytoplasms are compared and it is shown that automated cytoplasmic delineation can be performed 30 times faster than manual delineation, with an accuracy as high as 87%. The final image based measurements of mitochondrial mutation load are also compared to, and show high agreement with, measurements made using biochemical techniques.

    Approaches for increasing throughput andinformation content of image-based zebrafishscreens2011In: Proceeding of SSBA 2011, 2011Conference paper (Other academic)
    Abstract [en]

    Microscopy in combination with image analysis has emerged as one of the most powerful and informativeways to analyze cell-based high-throughput screening (HTS) samples in experiments designed to uncover novel drugs and drug targets. However, many diseases and biological pathways can be better studied in whole animals, particularly diseases and pathways that involve organ systems and multicellular interactions, such as organ development, neuronal degeneration and regeneration, cancer metastasis, infectious disease progression and pathogenesis. The zebrafish is a wide-spread and popular vertebrate model of human organfunction and development, and it is unique in the sense that large-scale in vivo genetic and chemical studies are feasible due in part to its small size, optical transparency,and aquatic habitat. To improve the throughput and complexity of zebrafish screens, a high-throughput platform for cellular-resolution in vivo chemical and genetic screens on zebrafish larvae has been developed at Yanik lab at Research Laboratory of Electronics, MIT, USA. The system loads live zebrafish from reservoirs or multiwell plates, positions and rotates them for high-speed confocal imaging of organs,and dispenses the animals without damage. We present two improvements to the described system, including automation of positioning of the animals and a novel approach for brightfield microscopy tomographic imaging of living animals.

    Affective touch in human–robot interaction: Conveying emotion to the Nao robot2018In: International Journal of Social Robotics, ISSN 1875-4791, E-ISSN 1875-4805, Vol. 10, p. 473-491Article in journal (Refereed)
    Abstract [en]

    Affective touch has a fundamental role in human development, social bonding, and for providing emotional support in interpersonal relationships. We present, what is to our knowledge, the first HRI study of tactile conveyance of both positive and negative emotions (affective touch) on the Nao robot, and based on an experimental set-up from a study of human–human tactile communication. In the present work, participants conveyed eight emotions to a small humanoid robot via touch. We found that female participants conveyed emotions for a longer time, using more varied interaction and touching more regions on the robot’s body, compared to male participants. Several differences between emotions were found such that emotions could be classified by the valence of the emotion conveyed, by combining touch amount and duration. Overall, these results show high agreement with those reported for human–human affective tactile communication and could also have impact on the design and placement of tactile sensors on humanoid robots.

    Past and Future Challenges for Railway Research and the Role of a Systems Perspective2019In: Proceedings of the 20th Congress of the International Ergonomics Association (IEA 2018): Volume VII: Ergonomics in Design, Design for All, Activity Theories for Work Analysis and Design, Affective Design / [ed] Sebastiano Bagnara, Riccardo Tartaglia, Sara Albolino, Thomas Alexander, Yushi Fujita, Cham: Springer , 2019, p. 1737-1746Chapter in book (Refereed)
    Abstract [en]

    Operational train traffic is dependent on an efficient traffic plan monitored and executed by the traffic controllers, the proficient maneuvering of the trains by the train drivers, and on the interaction, communication, and coordination between these two work roles. The railway research community, and the branch of industry itself, has called for an integrated systems perspective for the whole train traffic system to achieve an efficient performance. As human-human and human-technology interactions are natural parts of the socio-technical system of train traffic, the aim of this paper is to provide illustrative examples for why a systems perspective is needed for the future of railway research. Furthermore, we present the theoretical framework of distributed cognition (DCog) as a necessary addition to the theoretical and methodological toolbox of the Human Factors and Ergonomics (HF&E) discipline. To realize efficient and coordinated processes involved in organizing and executing operational train traffic, the paper proposes that the DCog framework should be implemented in the train traffic domain as a viable approach forward.

    The coordination between train traffic controllers and train drivers: a distributed cognition perspective on railway2018In: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, p. 1-27Article in journal (Refereed)
    Abstract [en]

    Although there has long been a call for a holistic systems perspective to better understand real work in the complex domain of railway traffic, prior research has not strongly emphasised the socio-technical perspective. In operational railway traffic, the successful planning and execution of the traffic are the product of the socio-technical system comprised by both train drivers and traffic controllers. This paper presents a study inspired by cognitive ethnography with the aim to characterise the coordinating activities that are conducted by train traffic controllers and train drivers in the work practices of the socio-technical system of Swedish railway. The theoretical framework of distributed cognition (DCog) is used as a conceptual and analytical tool to make sense of the complex railway domain and the best practices as they are developed and performed “in the wild”. The analysis reveals a pattern of collaboration and coordination of actions among the workers and we introduce the concept of enacted actionable practices as a key concern for understanding how a successfully executed railway traffic emerges as a property of the socio-technical system. The implications for future railway research are briefly discussed.

    Tool use and collaborative work of dock assembly in practice2017In: Production & Manufacturing Research, ISSN 2169-3277, Vol. 5, no 1, p. 164-190Article in journal (Refereed)
    Abstract [en]

    In order to deepen the understanding of the intrinsic interactions and interplay between humans, tools, and environment from a systems perspective, research in the wild (RITW) approaches have gained traction during recent decades as they provide a higher ecological validity of findings. This paper presents a RITW study, investigating how assembly, in this case dock assembly of forwarders, was done in practice. As our theoretical foundation, we used the framework of distributed cognition, which is one of the main pillars of RITW. The findings are presented in narrative form, describing and highlighting that the workers achieve an efficient production outcome by being integral parts of the whole production process and doing so through coordination of activities benefitting the shared goal of the distributed socio-technical system.

    Comparing and visualizing titanium implant integration in rat bone using 2D and 3D techniques2015In: Journal of Biomedical Materials Research. Part B - Applied biomaterials, ISSN 1552-4973, E-ISSN 1552-4981, Vol. 103, no 1, p. 12-20Article in journal (Refereed)
    Abstract [en]

    The aim was to compare the osseointegration of grit-blasted implants with and without a hydrogen fluoride treatment in rat tibia and femur, and to visualize bone formation using state-of-the-art 3D visualization techniques. Grit-blasted implants were inserted in femur and tibia of 10 Sprague-Dawley rats (4 implants/rat). Four weeks after insertion, bone implant samples were retrieved. Selected samples were imaged in 3D using Synchrotron Radiation-based CT (SRCT). The 3D data was quantified and visualized using two novel visualization techniques, thread fly-through and 2D unfolding. All samples were processed to cut and ground sections and 2D histomorphometrical comparisons of bone implant contact (BIC), bone area (BA), and mirror image area (MI) were performed. BA values were statistically significantly higher for test implants than controls (p<0.05), but BIC and MI data did not differ significantly. Thus, the results partly indicate improved bone formation at blasted and hydrogen fluoride treated implants, compared to blasted implants. The 3D analysis was a valuable complement to 2D analysis, facilitating improved visualization. However, further studies are required to evaluate aspects of 3D quantitative techniques, with relation to light microscopy that traditionally is used for osseointegration studies.

    Abstract [en]

    Technology has opened up more opportunities to find bet- ter partners, especially via online dating sites . In addition, technology related to love and sex currently goes far beyond online dating sites. Technology influences our intimate life more and more. Media started to pick up romantic rela- tionship between human beings and digital characters of- ten. Furthermore, today, many wearable devices to experi- ence virtual sex have come into the market. And also robots designed for having a sex with human beings are being de- veloped rapidly. Some might claim having a sex without love or without reproduction is just totally pointless. Or, having a sex with robots is totally “insane”. But apparently there are big market needs, and modern technology seems to be able to satisfy them. This paper explores how it is possible for us to feeling love or sexual desire for non-organic objects by conducting the interview survey, and also considers why people want to have technology for satisfying sexual desire from a philosophical perspective.

    Designing "Open Education": How does the ICT-based system function as a new medium of participation for sustainability?2013In: The possibilities of ethical ICT, Kolding: University of Southern Denmark , 2013, p. 33-36Conference paper (Refereed)
    Abstract [en]

    Information and communication technology (ICT) has developed and deployed rapidly since 1980’s. Until now ICT has been considered as one of the most important infrastructures in living in the present globalized society. Along with diffusion of personal computers and highly leveraging information on the web, the way of learning has been changing gradually. Hundreds universities, institutes and companies constructs and releases the “open education” platform based on ICT, for example iTunes U, TakingITGlobal and so on. These open education platforms are basically open for everyone who wants to learn by using contents on the website for free in so far as they can access the Internet. And the movement toward the construction and use of ICT-based education platform is supported by international organizations, such as the Centre for Educational Research and Innovation (CERI) in OECD and UNESCO’s project “the Virtual University and e-learning”.

    Technology democratization enforces a never-ending process of risk/responsibility harmonization through with ethical assumptions. However, it is crucial to debate the gender gap within our community (reasons) and explore the potential “outcome” of female contribution. This panel does not promote a direct hit with the sessions, although the intention is to be controversial and influencer concerning a latent problem inside our community.

    Abstract [en]

    The open education system based on Information and communication technology (ICT) can provide great opportunities for people to learn regardless of resident area, language, gender, age and so on. Currently people use it actively and build up new social networks as learning communities or study groups on the Internet. Shared knowledge and the process of sharing knowledge established through online communication are considered as key elements in the context of strengthen the individual and the country. In other words, creating the open education platform and content plays a role of designing a culture and society. However, it is not easy to realize the ideal concept of “open education” because people have many differences in language, culture, political system, ideology, thought, deployment of ICT et cetera. In order to create the open education system, which has a high degree of usability and effectiveness, we need to closely examine social roles and difficulties of the ICT-based education system in designing sustainable societies. And also the ICT-based educational system is established through the continuous human-computer interaction. Therefore, all participants get involved with developing the open education and each of them assumes a responsibility for making the open educational contents more abundant.

    Information and Communication Technology (ICT) creates novel products and services and promotes innovation in the whole of global society, and the amount of data, which we can gather and use, or even just see, is increasing dramatically. Searching and checking information on the Internet is our ordinary way of doing, people enjoy online shopping commonly and sometime look for their partners through the Internet. Internet, mobile networks and social media have flourished greatly in our daily lives, ICT has developed and deployed very dynamic and diverse as well. Particulary our communication patterns are greatly affected by permeation of social media into our daily life.

    Abstract [en]

    Do social media generate social capital beyond borders between the real and virtual spaces? If so, how do social media function in forming and maintaining social capital? From the beginning of 2011, a huge number of people have seen political turmoil stimulated by use of social media and felt the inner stirrings of people’s cooperative networks via social media. Thus, some people strongly stressed that social media has a great power to change authoritarian regimes from the global political issues perspective. On the other hand, we recognized how social media worked effectively from the local issues perspective, for example in the case of the massive disaster in Japan. Existing media such as TV and newspapers didn’t work well, the Japanese got and exchanged information through social media and in fact some victims were rescued based on information via social media. Both cases, political changes and massive disasters, show information transaction process has been supported by thin trust, generalized reciprocity and loosely tied people’s network, regardless of geographical borders or real/virtual spaces. And some users opened their opinions about governments’ policies or their discontent with the government through social media and discuss with others online. Through this discussing process, it seems that social media plays an important role in fostering a social network leading to social capital. This study reconsiders characteristics of social capital and its role in improving people’s lives through social media. It also examines how social media affects social capital processes, by giving a few examples of using social media under critical social situations.

    Social Media Supporting Democratic Dialogue2013In: Ambiguous Technologies: Philosophical Issues, Practical Solutions, Human Nature, Lisbon: Autónoma University , 2013, p. 36-43Conference paper (Refereed)
    Abstract [en]

    The term of “social media” appears in newspapers and magazines everyday and the huge number of people use social media actively in daily life. Nowadays, in the highly Information and Communication Technology (ICT) developed country Japan, Japanese people enroll in social media and evolve a new way of communicating with others based on the “virtual” social distance between them. Among social media, Twitter has been focusing on its strong power as the tool for political change recent years. While Twitter has of-expressed problems as well as the “traditional” social media, it is characterized by the limited number of characters, strong propagation and optional reciprocity. Those characteristics stimulate people’s communication online and bring about opportunities for social interaction and democratic dialogue. On the other hand, in the deluge of information, we need to nurture skills to utilize critical and rational way of thinking through dialogue not only between others also between themselves internally. This study explores characteristics of social media and differences between “traditional” social media and Twitter, and how the difference affects people’s information behavior in Japan.

    Balancing between the conflicting interests of different stakeholders in research2017In: European Business Ethics Network: Research / [ed] Ioannis Filos, Athens: Deree, American College of Greece College , 2017Conference paper (Refereed)
    Abstract [en]

    We in academia produce a lot of research in the form of papers, technologies, methods, medicines and so on. All those outcomes are of great importance for society and people. On the other hand, there are many stakeholders in the process of producing research outcomes nowadays. Researchers themselves are of course the main stakeholders because their career is dependent on research. However, when research projects are connected to various political goals or affect profits for industries, many other stakeholders like politicians and business people get involved to research activities as well. Especially industries offer a lot of research funds to academic projects, and actually today many collaborative research projects between industry and academia are in progress. Thus, research environments are very complex and morally challenging since many different and conflicting interests interfere. Many academic researchers believe that what they produce belongs to society, and that their work is there mainly to satisfy the interests and needs of society and people. But, at the same time, they need to fulfill the demands coming from research supporters who offer funds and research opportunities. In producing research of good quality, it is unavoidable and very important for researchers to make a fair choice between the quality of scientific research and the satisfaction of stakeholders’ demands. This paper explores how researchers make justice between these conflicting interests, what kind of ethical dilemmas and problems they face in their daily research activities, and how they solve the ethical problems. This study is the first step of a research project that focuses on how scientific research activities and outcomes become 'social' and 'valuable'.

    Do social media generate social capital?2012In: ICT, society and human beings / [ed] Gunilla Bradley, Diane Whitehouse and Angela Lin, Lisbon: IADIS Press , 2012, p. 133-136Conference paper (Refereed)
    Abstract [en]

    Do social media generate social capital beyond borders between the real and virtual spaces? If so, how do social media function in forming and maintaining social capital? This study is triggered by those simple questions. From the beginning of 2011, a huge number of people have seen political turmoil stimulated by use of social media and felt the inner stirrings of people’s cooperative network via social media. Thus, some people strongly stressed that social media has a great power to change authoritarian regimes from the global political issues perspective. On the other hand, we recognized how social media worked effectively from the local issues perspective, for example in the case of the massive disaster in Japan. Under the critical situation, where existing traditional media like phones, TV, radio and newspapers didn’t work, the Japanese got and exchanged information through social media and in fact some victims were rescued based on information via social media. Both cases, political changes and massive disasters, show information transaction process has been supported by thin trust, generalized reciprocity and loosely tied people’s network, regardless of geographical borders or real/virtual spaces. Therefore it seems that social media plays an important role in fostering a social network leading to social capital. This paper reconsiders characteristics of social capital and its role in improving people’s lives through social media. It also examines how social media influences social capital by giving a few examples of social media and social issues, more specifically, the political turmoil in Tunisia and big earthquake disasters in Japan.

    Abstract [en]

    This study explores how to improve and support researchers'ethical competence in scientic research and how to conduct research ethically, especially in research activities using Information and Communication Technology (ICT). Refining research ethics relating to ICT is unavoidable in the highly technological society of today, for example big data is used in different scientic research activities, and systems which support our daily lives are constructed based on the existing systems. In other words, technology reproduces technology itself. And almost all research activities need to use ICT through the whole research process. Moreover, researchers are required to be able to participate and react sensibly in ethical dialogues with society and citizens. Seen in that light, this study could be applicable not only to computer science and technology but also to a broad spectrum of research areas as the constructive notions of ethics, liberty and responsibility in research activity.

    ICT supported crisis communication and dialog2013In: The possibilities of ethical ICT, Kolding: University of Southern Denmark , 2013, p. 37-41Conference paper (Refereed)
    Abstract [en]

    This study explores how people use social media under serious social conditions, and how social media affects people’s behavior after a disaster based on the case of the March 2011 disaster in Japan. In this critical situation, where existing traditional media like phones, television, radio and newspapers did not work well, the Japanese exchanged and received information through social media. In fact some victims were rescued based on information via social media. Corresponding to people’s need, social media provided various services to support people immediately after the disaster. Therefore it seems that social media plays an important role in fostering a social network leading to horizontal communication, critical thinking, dialog; supporting social capital. This study reconsiders characteristics of social capital and its role in improving people’s lives and supporting democratic communication as well as the difficulties in people bonding together through social media.

    Regulation of potentially harmful contents on minors2012In: Equity, integrity and beauty in information law and ethics / [ed] Maria Botti, Kerkyra, Greece: Ionian Academy , 2012Conference paper (Refereed)
    Abstract [en]

    In democratic societies, freedom of expression is the indispensable right and duty of citizens. Although there are a few exceptions, it is generally considered that governments should not intervene and regulate this right. Both in digital and analog environments, sexual and violent descriptions are usually regulated by self-censorship of participants. However, trying to protect minors from potentially harmful contents by controlling and regulating them is very difficult. The definition of what is “potentially harmful contents on minors” varies depending on the values and on the culture of each social group. Moreover, along with the rapid spread of mobile phones and smartphones, it becomes more difficult for parents and teachers to control children’s access to harmful contents; something that might have been easier regarding the use of personal computers. Access to the Internet provides huge opportunities not only of visiting websites but also of participating in online communication such as Social Networking Service (SNS). An incredible surge of SNS evokes some issues in considering juvenile access to SNS, categorized roughly into three types. One is the very old and new problem in accessing the Internet, which is how to shield minors from harmful contents. Second is how to block inappropriate contact with a pedophile. Third is cyber bullying. SNS is a very new medium and its market and technology are evolving drastically and are constantly changing. Thus the agent of taking the lead in making and enforcing rules or self-regulation is still absent. Additionally, SNS services utilize the function of social graph actively, and third parties can provide contents and applications using open API. In response to these situations, European Commission implemented Safer Social Networking Principle for the EU, and United States released the guideline for SNS users and worked on SNS companies and users to promote voluntary efforts for using SNS properly. In Japan, mobile contents companies built the Content Evaluation and Monitoring Association (EMA) as a voluntary reviewing entity. However those measures don’t include any severe legal penalty. Those remain self-regulation relying on voluntary activities of private sectors. On the other hand, self-regulation itself is regulated by laws, social norms, market conditions and technological architectures. In this paper we discuss the conditions of regulation and self-regulation, and we explore some ideas about what would be the best way to regulate SNS.

    Responsibility and Competence in Political Ethics2014In: Proceedings International Political Science Association, 23rd World Congress of Political Science, 2014: Challenges of contemporay governance, Montreal, 2014Conference paper (Refereed)
    Abstract [en]

    At present, our society is globalized, chaotic, changing, and also highly affected by individualization. That is, it is more difficult for out society to reach goals or conclusions collectively as one nation or one society. Under the situation, society needs political leaders to gather individual values, interests and opinions, and to take a lead in making collective decisions in the proper manner. Political leaders are required to have ability of making decisions and acting in the best way for society. Their responsibility is high even for future generations. According to Weber there are two categories of ethics pertaining to politics and to political leaders. One is the "ethic of ultimate ends" and the other is the "ethic of responsibility". "Ethic of responsibility" of political leaders is considered as a critical element. It is perceived as a kind of ability to consider possible social options and their impact, and also to take responsibility of their consequences in the future. In this context, it is very well compatible to the idea of ethical competence. It binds together philosophy and modern empirical research on ethical decision making, opening up for interventions like training and education for political leaders.
