The influence of selected preservation methods and storage time on the content of antioxidants in blackthorn (Prunus spinosa L.) fruits
Authors: OLESIŃSKA KATARZYNA , SUGIER DANUTA , SĘCZYK ŁUKASZ 
Published: August 2019

The aim of the study was to determine the influence of selected methods of preservation and storage time on the content of antioxidants in blackthorn fruit (Prunus spinosa L.). Preserved fruits were stored for 13 and 26 weeks without light at room temperature (freeze-dried and convection dried) and at –20°C (frozen samples). It was shown that both the method of preservation and the storage time had significant influence on the content of polyphenols (anthocyanins, flavonoids, total polyphenols) and antioxidant properties (Fe3+ reduction strength) of blackthorn fruit. As the storage time progressed, the anthocyanins content decreased in all preservation variants. In the case of frozen fruit after 26 weeks of storage, the content of flavonoids (by 12.5%), total polyphenols (by 48%) and the ability to reduce the iron ions were increased (by 55%). In turn, in the dried fruits after this period, the anthocyanins content, the polyphenol content and reduction strength were reduced. The highest values of the parameters evaluated after the assumed storage time has been demonstrated in lyophilizates.
Lithostratigraphy of the Enon Formation (Uitenhage Group), South Africa

Published: August 2019

Abstract
The Uitenhage Group represents the earliest deposits that filled Mesozoic rift basins in the southern Cape of South Africa during the fragmentation of the supercontinent Gondwana. The sedimentology of the Enon Formation records the development of alluvial systems that drained the region since the onset of Gondwanan rifting, and therefore plays an important role in our understanding of early landscape evolution along the southern African continental margin. The mostly coarse conglomeratic unit was deposited continuously in actively subsiding, but separated, rift basins. As a result, the deposits are diachronous between basins and display highly varied thicknesses of up to well over 2000 m.

Published: August 2019

AbstractThe Karoo region of South Africa is an ideal laboratory to use ambient seismic signals to map the shallow subsurface, as it is a quiet and pristine environment with a geology that is relatively well known. Ambient seismic signals were continuously recorded for a ten week period between August and October 2015. The ambient seismic noise network consisted of two groups of 17 temporary, stand-alone seismic stations each. These were installed in the southeastern Cape Karoo region, near the town of Jansenville. Here we present data on the retrieval and coherency of Rayleigh surface waves extracted from the vertical component recordings. We reconstruct and show, for the first time in the southeastern Cape Karoo, estimates of Green's function from cross-correlating ambient noise data between stations pairs, which can be successfully used to image the subsurface. The stacked cross-correlations between all station pairs show clear arrivals of the Rayleigh surface waves. The group velocities of the Rayleigh waves in the 3 to 7 seconds period range were picked and inverted to compute the 2-D group velocity maps. The resulting 2-D group velocity maps at different periods resulted in a group velocity model from approximately 2 to 7 km depth, which shows a high velocity anomaly in the north of the study area, most likely imaging the denser, thick sedimentary basin of the Karoo (Carboniferous-Permian). To the south, the low velocity anomaly could correspond to the overlying Jurassic-Cretaceous sedimentary sequences of the younger Algoa Basin (Uitenhage Group).
Lithostratigraphy of the Kookfontein Formation (Ecca Group, Karoo Supergroup), South Africa
Authors: de V. Wickens H. , Cole D.I. 
Published: August 2019

AbstractThe Permian Kookfontein Formation forms part of the upper Ecca Group in the southwestern part of the main Karoo Basin of South Africa. It occupies a stratigraphic position between the underlying Skoorsteenberg Formation and the overlying Waterford Formation, with its regional extent limited to the cut-off boundaries of the Skoorsteenberg Formation. The Kookfontein Formation has an average thickness of 200 m, coarsens upwards, and predominantly comprises dark grey shale, siltstone and thin- to thick-bedded, fine- to very fine-grained, feldspathic litharenite. Characteristic upward-coarsening and thickening successions and syn-sedimentary deformation features reflect rapid deposition and progradation of a predominantly fluvially-dominated prodelta and delta front slope environment. The upward increase in the abundance of wave–ripple marks further indicates a gradual shallowing of the depositional environment through time. The upper contact with the Waterford Formation is gradational, which indicates a transition from deposition in an unstable upper slope/shelf margin environment to a more stable shelf setting.
Firefox Extension untuk Klasifikasi Komentar Spam pada Instagram Berbasis REST Services

Published: August 2019

Klasifikasi komentar spam pada Instagram (IG) hanya dapat digunakan oleh pengguna melalui sistem yang berjalan di sisi client, karena data IG tidak dapat dimanipulasi dari luar IG. Dibutuhkan sistem yang dapat memanipulasi data dari sisi client dalam bentuk browser extension. Penelitian ini berfokus pada pengembangan browser extension untuk Firefox yang memanfaatkan web services REST pada layanan cloud dengan platform Amazon Web Services (AWS). Browser extension yang dikembangkan menggunakan 2 algoritma klasifikasi, yaitu KNN dan Distance-Weighted KNN (DW-KNN). Extension ini mampu menandai komentar spam dengan mengubah Document Object Model (DOM) IG menjadi berwarna merah dengan dicoret (strikethrough). Metode pengembangan extension dilakukan dengan metode Rapid Application Development (RAD). Pengujian pada penelitian ini dilakukan pada hasil implementasi browser extension dan pengukuran akurasi web service (algoritma KNN & DW-KNN). Pengujian implementasi browser extension menggunakan metode pengujian fungsionalitas, dimana setiap fitur yang telah diimplementasikan diuji apakah sudah sesuai dengan spesifikasi yang telah ditentukan sebelumnya. Pengujian akurasi web service dilakukan dengan bantuan tool SOAPUI. Hasil pengujian extension adalah: (1) pengujian extension pada sembarang halaman web berhasil 100%, (2) pengujian pada halaman awal (default) IG berhasil 100%, (3) pengujian pada halaman profile suatu akun IG berhasil 100%, (4) pengujian pada suatu posting IG dan komentarnya, tidak selalu berhasil karena dipengaruhi oleh kemampuan algoritma pada web services, (5) pengujian untuk bahasa bukan Indonesia tidak selalu berhasil karena bergantung pada library bahasa, (6) pengujian untuk load more comments pada IG tidak selalu berhasil karena bergantung pada algoritma pada web services, dan (7) pengujian pilihan algoritma pada options extension berhasil 100%. Hasil akurasi rata-rata tertinggi algoritma KNN adalah 80% untuk k=1, sedangkan DW-KNN adalah 90% untuk k=2.
Os Extremos Da Mercantilização Da Vida Social Na Contemporaneidade Do Capitalismo:
Authors: Rodrigues Victor César Fernandes 
Published: August 2019

No presente trabalho, busca-se situar a problemática marxiana do fetichismo da forma-mercadoria no contexto contemporâneo do capitalismo. Nossa proposta é a de reivindicar, por um lado, a tese segundoa qual é da natureza mesma da forma-mercadoria manifestar na superfície das relações cotidianas a personificação das coisas e a reificação das pessoas. Por outro lado, pretendemos situar que atualmente a expansão das relações de troca mercantis reproduzem o recrudescimento do fetichismo inscrito nessa inversão, tornando cada vez maior a submissão das pessoas aos imperativos da forma-mercadoria do produto do trabalho humano. Na conclusão, pretendemos abordar as possíveis tendências econômicas e políticas abertas ao Brasil, no que tange ao rebatimento das inovações tecnológicas estruturadas em nome da chamada quarta revolução industrial ou indústria 4.0.

Communication: Documents on skin: tattoos and underlying messages
Authors: Ménard Elaine , Fortier Alexandre 
Published: August 2019

This project examines the tattoo as a document using 18 in-depth interviews. The preliminary analysis of the results indicates the importance of distinguishing between tattoos that bear meaning and those that are purely aesthetic, and the fact that the two types may coexist. They also emphasize the importance of preserving the original aspect of the tattoo , even when visually ill-loved or associated with bad memories, thus testifying to the documentary function of certain tattoos.
Interviews that attend to emplacement: the “walk-through” method
Authors: Polkinghorne Sarah , Given Lisa M. , Carlson Lauren 
Published: August 2019

Within library and information studies (LIS), there is growing awareness of the role ofthe body and its surroundings in people’s information and knowledge experiences.Predominant data collection methods, such as the sit-down interview, should bereexamined in light of this awareness. This paper examines interview methodstheoretically and empirically. First, this paper introduces the concept of emplacement, theinterrelationship of body, mind, and place, as a useful lens for challenging conventionalinterviewing practices. Second, this paper delineates the “walk-through” interview, whichin a study of undergraduates’ information behaviours prompted richer detail fromparticipants than did “sit-down” interviews. **Awarded Best Overall Conference Paper **
The Long Tail of Forgetting: Libraries, the Web 2.0, and the Phenomenology of Memory
Authors: Campbell D. Grant 
Published: August 2019

This paper uses Ricoeur’s phenomenology of memory to compare traditional library information systems and the Web 2.0: social software, tagging systems, file sharing and RSS. Both domains employ strategies of information rentention, searching, evocation and reproduction. But the Web 2.0 utilizes a vague principle of “findability,” which leads to more diverse tools and a more diffuse objectives.Cette communication utilise la phénoménologie de la mémoire de Ricœur pour comparer les systèmes d’information traditionnels des bibliothèques et le web 2.0 : les logiciels sociaux, les systèmes d’étiquetage, de partage de fichiers, et les fils de syndication. Les deux domaines utilisent des stratégies de maintien en fonction, de recherche, d’évocation et de reproduction. Cependant, le web 2.0 utilise un vague principe de « repérabilité » menant à des outils plus versatiles et à des objectifs plus diversifiés.

The University Library as Information Broker to Industry and Commerce
Authors: Pienaar Dr. Rae E. 
Published: August 2019

From the 1994 CAIS Conference: The Information Industry in Transition McGill University, Montreal, Quebec. May 25 - 27, 1994.The majority of libraries still provide the majority of their services for free. But fee-based information services attached to non-profit making institutions such as libraries is not a novel concept any longer. The information explosion has brought many changes to, amongst others, the university library and at present industry and commerce rely heavily on the expertise offered by the staff of those libraries.This paper does not propose to address any ideological issues of "feeversus free" but would rather focus on the following: 1 the need for industry and commerce for utilizing the university library and its resources;2 the university library as information broker with reference toinformation skills complemented with specialized subject knowledge and experience 3 the organization of the wide range of services offered and the pricing of these services; and4 a short, but detailed description of INFOBANK, a dynamic andsuccessful regional fee-based information service to industry and commerce at the library of the University of Stellenbosch, South Africa.A university library can therefore be even more effective in promoting access to information by making it available in the community, albeit for a price. Libraries interested in establishing such fee-based services should nevertheless be aware of the pitfalls associated with the creation and management of these services. Knowledge of the latter will undoubtedly help establish a programme that serves the needs of clients whilst contributing towards the overall image of the parent institution.
Stratégies informationnelles en milieu professionnel : du réseau personnel à la Toile
Authors: Paganelli Celine , Mounier Evelyne 
Published: August 2019

Cette communication s’intéresse au lien entre l’expertise des individus, le contexte de la tâche et les stratégies de recherche d’informations dans un cadre professionnel. Des entretiens, menés auprès d’employés d’une banque, montrent que les types de recherche et le choix des ressources sont conditionnés par les objectifs et les contraintes liés à l’activité de l’individu mais aussi à l’activité de l’entreprise. This article focuses on the link between individual expertise, the context of the task, and information searching strategies in a professional setting. Interviews with bank employees show that the types of research and the choice of resources depend on the goals and constraints of individual as well as corporate activities.

Connecting with Community: The Importance of Community Engagement in Rural Public Library Systems
Authors: Howard Vivian , Reid Heather 
Published: August 2019

Urban public library systems have been the primary focus of study for community engagement and community-led approaches. Nova Scotia is largely rural and sparsely populated, with a dwindling and aging rural population. This presentation examines how community engagement can connect Nova Scotia’s rural public libraries with their communities. Les systèmes de bibliothèques publiques urbaines ont été le principal objet d’investigation pour l'étude de l'engagement communautaire et des approches à visée communautaire. La Nouvelle-Écosse est essentiellement rurale et peu peuplée, avec une population rurale en déclin et vieillissante. Cet article examine comment l'engagement communautaire peut établir la connexion entre les bibliothèques publiques rurales de la Nouvelle-Écosse et leurs communautés.
Objects, Identity, Storytelling, and Finding Common Ground
Authors: Howarth Lynne , Quirke Lisa 
Published: August 2019

While research literatures focused on memory and storytelling address the role of objects relative to (1) individual self-narrative and the expression of identity, and (2) group narrative and the expression of communal identity, the link between individual and group narrative and identity as afforded by objects does not appear to have been made, either explicitly, or as a locus of formal study. This paper will report on outcomes from the first of a multi-phase study exploring the role of objects in negotiating individual identity within a group context, where the articulation of a common identity is mandated by a coordinated, communal assembly or collaborative curation of objects – a community “display case” in the form of a public exhibition at a neighbourhood library. La littérature scientifique axée sur la mémoire et la narration aborde le rôle des objets relatifs à (1) l’auto-narration individuelle et l'expression de l'identité, et (2) la narration de groupe et l'expression de l'identité communautaire, mais il semble que le lien n’a pas été fait entre le récit individuel et le récit collectif et les identités, tel que fourni par les objets, que ce soit explicitement ou comme lieu d'une étude formelle. Cet article rend compte des résultats de la première phase d'une étude qui en comporte plusieurs portant sur le rôle des objets dans la négociation de l'identité individuelle dans un contexte de groupe, où l'articulation d'une identité commune est rendue obligatoire par une assemblée communale coordonnée ou par la conservation en collaboration d'objets - une communauté "vitrine" sous la forme d'une exposition publique dans une bibliothèque de quartier.
Knowledge Sharing by Canadian Non-Profit Organizations (NPOs) with Community Stakeholders
Authors: Given Lisa M. , Rathi Dinesh 
Published: August 2019

This paper presents results of a nation-wide online survey of Canadian Non-Profit Organizations (NPOs) on their knowledge sharing approaches when engaging with the general public, including volunteers and other community stakeholders. The findings presented in this paper are based on qualitative and quantitative data analyses of over 1200 responses received. The findings reveal that NPOs use different approaches such as emails, text-messaging, formal and informal in-person interactions and social media to share knowledge with various community stakeholders. Cet article présente les résultats d'une enquête en ligne à l'échelle nationale auprès d’organismes canadiens sans but lucratif (OSBL) sur leurs approches concernant le partage des connaissances lors de leurs rapports avec le grand public, y compris les bénévoles et d'autres intervenants de la collectivité. Les résultats présentés dans le présent article sont fondés sur l’analyse de données qualitatives et quantitatives provenant de plus de 1200 réponses reçues. Les résultats révèlent que les OSBL utilisent différentes approches telles que le courriel, la messagerie texte, des interactions personnelles formelles et informelles ainsi que les médias sociaux pour partager des connaissances avec divers intervenants communautaires.
