Supporting Answerers with Feedback in Social Q&A

Prior research has examined the use of Social Question and Answer (Q&A) websites for answer and help seeking. However, the potential for these websites to support domain learning has not yet been realized. Helping users write effective answers can be beneficial for subject area learning for both answerers and the recipients of answers. In this study, we examine the utility of crowdsourced, criteria-based feedback for answerers on a student-centered Q&A website, Brainly.com. In an experiment with 55 users, we compared perceptions of the current rating system against two feedback designs with explicit criteria (Appropriate, Understandable, and Generalizable). Contrary to our hypotheses, answerers disagreed with and rejected the criteria-based feedback. Although the criteria aligned with answerers' goals, and crowdsourced ratings were found to be objectively accurate, the norms and expectations for answers on Brainly conflicted with our design. We conclude with implications for the design of feedback in social Q&A.Comment: Published in Proceedings of the Fifth Annual ACM Conference on Learning at Scale, Article No. 10, London, United Kingdom.

Designing for Embodied and Rich Interaction in Home IoT

Internet of things (IoT) artifacts form systems where touchscreen and speech interaction is the norm. As IoT systems are inherently open (artifacts can be added or removed, software can be updated), we observe that the natural state of an IoT system is changed, “growth.” This chapter describes a designerly experiment exploring how to design for embodied and rich interaction in these “growing” IoT systems. We present four design cases showcasing four approaches to the design challenge: a hybrid, a modular, a shape changing, and a service approach. We describe and appraise the four approaches and discuss insights from the designerly experiment. We conclude that it is indeed possible to design for embodied and rich interaction in “growing” IoT systems and see our work as a first step toward diversifying IoT interaction styles

Trusting organizations:The institutionalization of trust in interorganizational relationships

Recent research on interorganizational trust has stressed the need to develop a deeper understanding of the multi-level nature of this construct. This article focuses on trust on different analytical levels in an interorganizational context, and on the hitherto underspecified connections between these. Based on an institutionalization approach, it revisits the classic question: (how) can organizations trust each other? To do so, we consider organizations as objects of trust and reappraise the transferral from interpersonal to interorganizational trust in "facework" (Giddens, 1990). We also examine the conflicts and struggles of trust and power that can arise from this process between boundary spanners and their organizational constituents. Next, we consider organizations as subjects of trust in interorganizational relationships. We detail the institutionalization of trust and its reproduction on an organizational level, and how it can be transmitted to new generations of organizational actors, creating path-dependent histories of trust which are truly interorganizational. Taking up the theme of trust and power, we analyze ways in which the institutionalization of trust can entail that of power, too, and examine the implications of this from a critical point of view. We conclude that in interorganizational trust, both the subject and object of trust move across analytical levels, and further, that this movement demonstrates the significance of the organization as a distinct entity that can be both trusted and trusting

Reviews Matter: How Distributed Mentoring Predicts Lexical Diversity on Fanfiction.net

Fanfiction.net provides an informal learning space for young writers through distributed mentoring, networked giving and receiving of feedback. In this paper, we quantify the cumulative effect of feedback on lexical diversity for 1.5 million authors.Comment: Connected Learning Summit 201

SISTEM PEMBUKTIAN DAN ALAT BUKTI TERHADAP TINDAK PIDANA PENCUCIAN UANG MENURUT UNDANG-UNDANG NOMOR 8 TAHUN 2010

Tujuan penelitian ini yaitu untuk mengetahui bagaimana pengaturan sistem pembuktian dan alat bukti dalam Undang-Undang Nomor 8 Tahun 2010 tentang Pencegahan dan Pemberantasan Tindak Pidana Pencucian Uang dan bagaimana efektivitas pembuktian tindak pidana pencucian uang menurut Undang-Undang Nomor 8 Tahun 2010, yang dengan metode penelitian hukum normatif disimpulkan: 1. Pengaturan sistem pembuktian Undang-Undang Nomor 8 Tahun 2010 yaitu terhadap ketentuan umum sistem pembuktian KUHAP (Pasal 183 dihubungkan dengan Pasal 66) bahwa hakim tidak boleh menjatuhkan pidana kepada seorang kecuali apabila dengan sekurang-kurangnya dua alat bukti yang sah, ia memperoleh keyakinan bahwa suatu tindak pidana benar-benar terjadi dan bahwa terdakwalah yang bersalah melakukannya; di mana kepada terdakwa tidak dibebani kewajiban pembuktian; maka ketentuan khusus dalam Undang-Undang Nomor 8 Tahun 2010 yaitu terdakwa ada dibebani kewajiban pembuktian, yakni menurut Pasal 77 dan Pasal 78 terdakwa wajib membuktikan bahwa Harta Kekayaannya bukan merupakan hasil tindak pidana. Sedangkan pengaturan alat bukti Undang-Undang Nomor 8 Tahun 2010, yaitu selain alat bukti menurut KUHAP, juga sudah ditambah dengan alat bukti (dokumen) elektronik sebagai alat bukti. 2. Peran sistem pembuktian dalam Undang-Undang Nomor 8 Tahun 2010 untuk meningkatkan efektivitas pembuktian terlihat dari beberapa putusan pengadilan di mana tidak dapatnya terdakwa membuktikan bahwa harta kekayaannya bukan merupakan hasil tindak pidana, telah digunakan oleh hakim untuk memperkuat pembuktian Jaksa Penuntut Umum bahwa terdakwa telah melakukan tindak pidana asal (korupsi) dan tindak pidana pencucian uang. Sedangkan adanya alat bukti (dokumen) elektronik telah berperan penting sebagai dasar bagi Pusat Pelaporan dan Analisis Transaksi Keuangan (PPATK) untuk memeriksa dan melaporkan adanya aliran dana ke rekening terdakwa. Kata kunci: sistem pembuktian; alat bukti; pencucian uang
