The development and validation of “preference diversity” and “openness to novelty” scales for movie goers
Authors: Tang Muh‐Chyun , Chang Mei‐Mei , Lin Sung‐Chien
Published: February 2019

This paper reports the results of an ongoing research to develop and validate scales for two psychological constructs: “preference diversity” and “openness to novelty”, that we believe to be important factors in users' responses to movie recommendations. Question items were created based on literature review and the results of a focus group interview. A questionnaire interview that consists of the candidate question items were performed so the validation and purification of the scales can be performed (N=191). Through exploratory factor analysis, five items were eventually selected for each construct. A user study (N=293) were subsequently followed which collected both users' responses to the scales and their actual movie viewing history of a sample of 220 movies. The scales were shown to possess both stability and internal consistency. Results showed that the participants' preference diversity score were correlated with the diversity of the movies seen, as measured by the number of movies, the number of movie genres, and the average dissimilarity of the movies seen. Furthermore, those who have higher openness to novelty also tended to watch and appreciate more obscure films.
Predicting the dynamics of scientific activities: A diffusion‐based network analytic methodology
Authors: Zhang Yi , Wang Ximeng , Zhang Guangquan , Lu Jie
Published: February 2019

With the rapid explosion of information and the dramatic development of bibliometric techniques in the past decades, it becomes a challenge to comprehensively, extensively, and efficiently understand science maps. Aim‐ing to explore in‐depth insights from science maps and predict the dynamics of scientific activities, this paper, based on the co‐occurrence statistics of terms derived from scientific documents, proposes a diffusion‐based network analytic methodology to conduct the prediction study from two aspects: the research interest of scien‐tific researchers and the evolutionary directions of scientific topics. A case study on academic articles down‐loaded from three leading journals in the field of bibliometrics demonstrates the feasibility of the methodology. The future directions of bibliometrics are identified, such as the application of information technologies to tradi‐tional bibliometric data, the interactions between bibliometrics and science, technology, and innovation policy issues, and individual‐level bibliometrics. The results also provide recommendations as potential research inter‐ests for a set of experts. The proposed method could be a toolkit to conduct forecasting studies for a given technological area or a given discipline, and a recommender system to assist academic researchers in identify‐ing potential research interests and extended areas.
Rules of the game: An interactive panel discussion about how institutions shape information
Authors: Allard Grant A. , Sawyer Steven B.
Published: February 2019

We focus on the roles that institutions play relative to information behavior. Our working definition of institution is the formal and informal constraints that form the basis for exchange, relationships, and decision‐making. We know that institutions play significant roles in the creation, management, and uses of information. And, scholars have long recognized that institutions have both direct and indirect impacts on the sustainability and ethical value of information. What is less clear are the ways in which institutions and people's information behaviors are mutually‐constituted. The goal of this panel is to highlight particular opportunities for expanding the current and modest level of attention to studying the roles of human institutions relative to information. To do so, this panel will involve the audience in a lively conversation about how information science views the role of institutions in information behavior. It includes a participatory design structured activity that will engage the audience in identifying how existing threads of research are making contributions and key areas of further inquiry. The panel will begin with dialogue sharing insights of scholars and practitioners who are interested in data governance, information behavior, organization of information, and knowledge management. Then the panel will engage the audience in an interactive activity that explores emerging research streams and questions.

Everyday documentation of arts and humanities collections
Authors: Graf Ann , Fulton Crystal , Jackson Amy , La Barre Kathryn , Walsh John , Tilley Carol , Lucky Shannon , Gorichanaz Tim
Published: February 2019

Formal institutions can only collect, document and provide access to a limited number and type of materials in limited ways. Thus, institutions miss out on collections or aspects of description that may be culturally important (to underserved groups, to small subcultures, to countercultural groups, etc.), which introduces myriad ethical issues. This panel will focus on “everyday documentation” of arts and humanities‐based collections done by those outside libraries, archives, and museums, and how such documentation practices can and should inform institutional practice and technological developments. The panel consists of a diverse group of academic researchers and practitioners working with a variety of arts and humanities collections. This panel is a program of the SIG for Arts and Humanities (SIG‐AH).
Contexts, critiques, and consequences: A discussion about educational data mining and learning analytics
Authors: Jones Kyle M. L. , McCoy Chase , Crooks Roderic , VanScoy Amy
Published: February 2019

The capture, aggregation, and analysis of student data is becoming ubiquitous at all levels of education—from primary to post‐secondary—as institutions increase their adoption of information technologies to serve administrative and educational ends. In part, this has led to a growing interest among education scientists and administrators in strategically mining and analyzing troves of data in order to uncover student behaviors and intervene in student life. As is the case in other contexts where actors are pursuing Big Data's supposed benefits, educational data mining is fraught with moral, ethical, and political conflict. The panel is composed of four researchers who analyze and critique educational data mining practices and learning analytics initiatives in particular micro‐and macro‐contexts, including academic libraries and professional advising, urban schools, graduate‐level online learning, and higher education generally. Each panelist also represents a unique conceptual background, pulling from work in information ethics and policy, critical data studies, documentation studies, and higher education policy to empirically analyze and critically evaluate tools, systems, practices, policies, and values. Through their individual but thematically intertwined perspectives, the panelists will present their research and lead audience members in discussion.

Findings demonstrated various relationships between the perceived need for topical learning and other variables such as topic familiarity, search system, and user confidence for completing searches.
The effect of demoting near‐duplicate pictures
Authors: Bergman Ofer , Tucker Simon , Dahamshy Somaya
Published: February 2019

People often take several pictures of the same situation “just in case something goes wrong”. As a result, their picture folders tend to be cluttered with near‐duplicate pictures. These near‐duplicate pictures reduce the efficiency of retrieving a specific picture as they compete for the users' attention. To address the problem of near‐duplicates, we developed Duplipix, a working prototype that identifies near‐duplicate pictures and piles them in a stack. When a user hovers the mouse over a stack, it opens allowing the user to select one or more of the near‐duplicate pictures. In an initial within‐subjects evaluation, we asked our 82 participants to retrieve a random picture from the same collection ‐ with and without DupliPix. The use of DupliPix resulted in significantly faster picture retrieval, and the majority of participants indicated that using it is easier, more aesthetic and interesting than the standard picture presentation. They would also like DupliPix to be included in their next operating system.
Voice of children: Children in the restrictive mediation of smartphone use
Authors: Cheng Wenting , Yang Mingyi , Wang Jun
Published: February 2019

Parents set rules and regulations about children's media use, which is called restrictive mediation. This study aims to understand how children describe their behaviors in and attitudes to restrictive mediation of smartphone use in the family context. We conducted a narrative inquiry with 47 Chinese children, ages 7 to 12. Then we used semi‐structured coding method on the text transcribed from three types of collected data, including painting, written text and recording of the narrative. The study found two roles of children in the restrictive mediation process: children being monitored and children as the intervener. When the children are monitored by their parents, sometimes they disagree with their parental mediation when their parents' behaviors are also questionable. Parents should set an example for their kids and discipline themselves' media use first. On the other hand, children could also be the intervener of their parental media use. Although the intervention from children is less effective than the parental mediation, children do play some role in contributing to cultivating good family media use habits.

Published: February 2019

One of the most intriguing developments in online activism is the emergence of hashtag activism. However, digital activism research has mainly investigated the networked and connective features. This study examined the topical and semantic aspects of the #MarchForOurLives network in Twitter through social media analytics. The extracted topics mainly supported the #MarchforOurLives movement, and the event's agenda and the digital movement presented positively skewed sentiment.
Working with Indigenous communities: Reflections on ethical information research with Ngarrindjeri people in South Australia
Authors: Du Jia Tina , Haines Jelina
Published: February 2019

In this paper, we reflected on the ethical information research based on our two studies conducted with an Indigenous community in South Australia. The first study was about understanding how Indigenous people interact with information and communication technologies (ICTs) on their traditional land and how they perceive the role of ICTs in the community development. The second study focused on Indigenous knowledge and experiences sharing in the traditional society. Ethical investigations on Indigenous people's information and knowledge practices will contribute to information research with marginalized groups.
Exploring linked data benefits for digital library users
Authors: Fenlon Katrina , Jett Jacob , Dubnicek Ryan , Cole Timothy W. , Kudeki Deren
Published: February 2019

Linked open data technologies seem likely to offer significant benefits for digital library users. So far, however, these benefits remain largely speculative despite growing momentum toward the application of linked data in libraries. This paper reports on an exploratory user study to evaluate the use of linked data with digital library special collections. This pilot study assessed features designed to contextualize search results and representations of primary sources, and features that leverage linked data to offer analytic insights. Digital library users were most excited by applications of linked data that provide new, analytic information, and which simultaneously serve to open up new avenues for research within and beyond individual collections.
Shifting standards: Participative dimensions of information literacy
Authors: Gazan Rich , MacLean Katie , Wahl Natalie
Published: February 2019

Information resources and practices have always been social, but traditional information literacy instruction tends to prioritize a model of an individual searcher evaluating library‐curated resources, while social collaboration tools and user‐generated content sites provide more participative paths and practices for research at all levels. Using document analysis of the information literacy instructional materials of 42 institutions, we investigate the extent to which information literacy instruction incorporates participative standards, resources and practices. The findings suggest that while information literacy standards and frameworks are evolving to encompass participative resources and practices, only 21% of the institutions studied inscribed participative resources and practices into their instructional materials. This visual presentation will be designed to elicit discussion about the ways in which document analysis may fail to capture the participative practices in information literacy instruction, to inform our ongoing research.
Finding trafficked children through crowdsourcing
Authors: Goh Dion Hoe‐Lian , Lee Chei Sian , Guo Hang
Published: February 2019

Tackling child trafficking requires a multi‐pronged approach from government and non‐government organizations as well as individuals. In this paper, we introduce Zhongxun, a crowdsourcing platform for finding missing children that have been potentially trafficked. Users submit photos of children whom they suspect may be victims of trafficking. Zhongxun uses a facial recognition algorithm to match the submission against its database of photos missing children and returns those that are similar for followup action. Users may also provide feedback on the matches to improve the facial recognition algortihm. Zhongxun is a live system and is currently being used in China.
Using virtual worlds to investigate perceived affordances on learned navigation and objective location performance
Authors: Haggerty Kenneth Carter , Cosgrove Peter John , Griffin Joseph Gregory
Published: February 2019

Navigation in virtual worlds is vital for users to move about effectively, complete objectives, and interact with one another and the environment. The ability to accurately orient oneself within a virtual world is essential for successful engagement in video games, simulations and learning environments. This study investigated the effects of perceived affordances on learned navigation and objective location performance within a virtual world. We hypothesized that such perceived affordances impede the learning of virtual geography by fostering reliance on “artificial” cues instead of real space navigation techniques such as the observation of landmarks, spatial orientation, sense of time and distance travelled. The presence of perceived affordances was not significant in predicting retention accuracy. However, the presence of perceived affordances was a significant predictor of objective location performance.
Video ethnographic documentation of stories and cultural practices with Indigenous Elders
Authors: Haines Jelina , Du Jia Tina , Trevorrow Ellen
Published: February 2019

This visual presentation reflects on the broader uses of video as a valuable tool for ethical recording of the stories and cultural practices of Indigenous Elders. The opportunities afforded by the use of the video were threefold, by its impact on the accuracy, truthful engagement, and connection with the Indigenous community. The inclusion of various segments of video in this paper shone a light on issues associated with ethical concerns such as anonymity and maintaining the integrity of recorded data. Thus, to ensure that the collective knowledge was shared in line with traditional laws and protocols of the Ngarrindjeri Nation. Our findings have significant implications for library and information researchers and professionals who gather video data from within (and about) Indigenous communities.
Supporting student agency with transmedia
Authors: Hovious Amanda , Shinas Valerie Harlow , Harper Ian
Published: February 2019

Student agency is defined as a student's sense of self‐control over his or her educational experiences. It is a critical aspect of learning among adolescents. One way to promote student agency in the classroom is through the integration of texts and tools that allow students to become producers and consumers of content. Transmedia—the creation and sharing of narrative across media—is such a tool. This poster presentation illustrates how transmedia can be used to support student agency and engagement, drawing on a foundational case study of middle‐grade students who interacted with the project, Inanimate Alice, an interactive novel that follows the adventures of Alice, a globetrotting girl who wants to be a game designer when she grows up. Future directions of the project are demonstrated via a new iteration of Inanimate Alice, a virtual reality (VR) gap story called Perpetual Nomads. The audience may experience Perpetual Nomads with a VR headset and learn about its implications for fostering student agency based on beta testing of the story with middle‐grade students. The presenters also discuss an upcoming research initiative that will further test the impact of Perpetual Nomads on digital and technological literacies—an important avenue for fostering student agency.
Unraveling scientists' multiple data roles dealing with genomic data
Authors: Huang Hong
Published: February 2019

This study contributes to a better understanding of 135 genomics scientists' perception about their data roles in genome curation work. Our study was guided by previously identified sixteen data role items (Salomone et al., 2011), and intended to define a model of groupings for data roles in genome curation. Analysis of the results revealed that genomics scientists have specific sets of data roles in the genome curation work. These data role items were reduced to four factor constructs. Both data producer and data custodian are ranked the highest, followed by data manager, and data consumer. The findings indicate that genomics scientists are primarily dealing with reusing and wrangling data (e.g., cleaning up the raw data across platforms and databases). The constructs defined by this study advance the understanding of data roles and their relationships in genomic data curation. In addition, the resulting data role model can serve as a valuable resource to genome scientists for assigning data curation tasks, training and data management policies development.
Data‐activism as civic engagement: Forming a narrative to foster social change on gun control in the United States
Authors: Khan Hammad Rauf , Onye Uriel Uzochukwu , Du Yunfei
Published: February 2019

This research evaluates data activism on the popular social media website twitter. The study focused on the predominant debate between the pro‐gun and anti‐gun activists in the United States. Such factors as data bias, ambiguity, and inaccuracies may occur when either feuding party shares data on gun violence statistics through twitter. The researchers adopted a veracity assessment synthesized from previous studies, which focuses on three main aspects 1) objectivity/subjectivity 2) truthfulness/deception, 3) credibility/implausibility. The preliminary research focused on finding data influencers on twitter through the NodeXL application and studying their tweets through content/text analysis. Results indicate that both sides of the debate are misrepresenting gun violence data in the United States to put forward their own agenda.
Exploring the relationships between freedom of information and institutional information management in the Chinese government: An empirical study
Authors: Li Siyi
Published: February 2019

The Regulation on Opening Government Information of the People's Republic of China ‐ the Chinese version of Freedom of Information (FOI) law in other contexts ‐ was issued by the State Council in 2007 and took effect the following year. Similar to other FOI laws, the regulation stipulates two approaches for disclosing information and they are proactive disclosure and disclosure‐by‐request (DbR). This research aimed at exploring the relationships between DbR and institutional information management in China. Twenty‐five institutions of the State Council were decided to be data sources, from which data were collected by browsing websites and sending information requests. This presentation reports on the findings of the study and the future work that should follow up on the study.
Post‐checkout (Non‐)usage of Library Digital Content
Authors: Lieu Angela , Zhao Dangzhi
Published: February 2019

The present study analyzed a large urban Canadian public library's data (2013‐2017) from Rakuten OverDrive to identify patterns, trends, and potential implications related to post‐checkout non‐usage (material that is checked out by a user, but subsequently never opened and/or downloaded) of library digital content. It was found that over 12% of the more than 1.1 million checkouts of digital content via OverDrive in 2017 were never opened, causing a waste of over $10,000 USD on metered access eBooks alone; this figure will likely increase in the coming years based on the trends found in this study. Juvenile and non‐fiction eBooks are most likely to be checked out and go unused. These findings may shed light on ways libraries and digital content vendors might improve the efficiency of digital content lending, and serve to inform collection management and user‐targeted marketing and solutions.
The performance of reading appeal descriptors for fiction: From the perspective of indexing consistency
Authors: Lin Chi‐Shiou , Wang Yi‐Yu
Published: February 2019

In this paper we describe indexer agreement and disagreement on the application of appeal descriptors on adult fiction. The appeal descriptors developed by Ebsco NoveList were used for the testing. The analysis found that about 1/3 of the appeal descriptors were of high use, but indexer inconsistency was generally high for those descriptors. In contrast, only a very small number of descriptors were of high use and at the same time of higher indexer consistency.
New international students' social information practices during transition to their host country
Authors: Oh Chiyoung , Butler Brian S.
Published: February 2019

As newcomers, international students face information challenges in unfamiliar environments. Studies have reported that social and online resources, such as friends and the Internet, are their important sources of information, but research is less clear about how international students seek information through social sources. This paper examines social information practices of new international students in a U.S. university during adjustment to their new local environments. Also, based on prior studies, we investigate how international students' socio‐national context, specifically the degree to which there are co‐nationals in one's local environments, shapes their social information practices. Findings show that international students from common countries of origin (China, India, and Korea) developed online and mobile communities with co‐national students and shared local information among them while most international students from other less common countries did not engage in such co‐national networking and information practices. This paper suggests that information behavior theories account for people's socio‐national contexts to better inform research and practice involving internationally mobile individuals and groups.

Tracing social question and answer users' interaction patterns
Authors: Sin Sei‐Ching Joanna , Lee Chei Sian , Theng Yin‐Leng
Published: February 2019

The study analyzed social question and answer (SQA) threads on Stack Overflow to investigate users' interaction patterns within an SQA thread and how these patterns related to the likelihood of receiving an acceptable answer. Robert Bales' Interaction Process Analysis was used to code the data. Analysis of 125 threads (844 posts) showed differences in response time and top interaction sequences. A significant difference was found in IPA.2 (shows tension release), a category in IPA's social‐ emotional area. This suggests that users' interactions on SQA, including their emotion management, are worth investigating.
The technology information‐seeking behaviors of school librarians
Authors: Smith Daniella , Schultz‐Jones Barbara , Farabough Michelle , Parcha Harshita
Published: February 2019

The purpose of this poster is to present the results of a study implemented with 448 school librarians, designed to understand their technology information seeking behaviors. The results indicate that school librarians' primary source of information about technology are school district professional development opportunities. Other popular activities for learning about technology include establishing personal learning communities and attending conferences and events from professional organizations. While most (54.3%) of the participants attended professional development 3 or more times a year, most of them did not survey teachers and students about their technology needs. Just 49.7% of the respondents participated in the technology planning process at their schools. These results are important for understanding how to design degree program and continuing education opportunities that prepare school librarians for their technology implementation responsibilities. QR codes will be embedded in the poster to share additional resources about the school librarian's role in implementing technology in schools.

Reading around the world: A web‐based application for creating a communal knowledge base of reading materials
Authors: Tamim Limor , Staiger‐Williams Eleri
Published: February 2019

Reading has many benefits, and has been shown to improve verbal abilities, concentration, imagination, and memory. Diverse reading materials have also been shown to reduce prejudice; perspectives drawn from different experiences and locales evoke empathy in the reader. To encourage diverse perspective taking, the Reading Around the World Challenge (RAWC) encourages people to read one book from every country. However, there is a lack of materials available for some countries, and existing books are not well known. Further, challengers take part individually or within existing social groups, and there is currently no means of exchanging book lists with other RAWC participants. To address this issue, we created RtWTrack, a web‐based prototype, which features a publicly available book database and visual map, that aggregates bibliographic data about reading materials and makes it publicly available.
What type of domain knowledge is cited by articles with high interdisciplinary degree?
Authors: Wang Yuzhuo , Zhang Chengzhi
Published: February 2019

Interdisciplinary studies require integration of principles, theories and practices from multiple disciplines. What type of domain knowledge will be applied more in such researches? Since scientific paradigms differ in fields, this paper takes computer science (CS) as a case and investigates utilization patterns of CS knowledge in articles from PLOS One with high interdisciplinary degree (IDD) by citation content analysis. Since scholars usually organize and indicate used knowledge in methodology, we study articles which cite CS articles in this section. After extracting citation content from citing articles, we identify the cited knowledge and analyse the type of cited knowledge. Experimental results show that: In the PLOS One articles which cited the CS knowledge, algorithm is the most used knowledge type and the most used object is random forests. Our study can be applied to understand how articles with high IDD use the knowledge from other disciplines in the future.
Health data accessibility: A preliminary study of biotech and medicine industry startup stakeholders
Authors: Wang Zih‐Han , Jeng Wei
Published: February 2019

Recent research has been emerging on the issues related to health data and informatics; however, there is a dilemma between data accessibility and ethical concerns in today's biotech and medicine industry (BMI) development. Conducting a case study through qualitative interviews of nine participants, we investigate the actual practices that the BMI startup community engages in while accessing and collecting health data for their businesses, as well as the insights of those who are eager to change and improve the current environment. Our preliminary results reveal the high cost of accessing and collecting clinical data in BMI fields, not only in terms of monetary price but also the strict regulations. Interestingly, rather than merely relaxing the regulations, many BMI startups hope that the regulations become more transparent and well‐rounded.
Precision poverty relief in China ‐ The role of information and information technology
Authors: Xie Sherry L. , Jiao Chenyue
Published: February 2019

Precision poverty relief, a similar concept to targeted poverty relief, has gained tremendous momentum in China since 2013 when it, as a new strategy to the lasting anti‐poverty battle in China, was officially acknowledged by the Chinese Central Government. A series of policies and implementation plans were subsequently issued, either dedicating themselves to this new strategy or to include it as a critical part of a more encompassing measure. To state it is new is not to suggest that the idea only emerged in 2013 but to emphasize its gain of official recognition. In addition, precision poverty relief is reviewed as new in recent years because of the new developments and deployments of information technologies in China, or, as by its Chinese expression, informationalization. This visual presentation reports on the preliminary findings of the project Digital Information and Societal Change, a subtask of the Records‐Centred Digital Information Management Theory and Mechanisms (DI{R}Mtm), which aimed at examining the role of information and informationalization in relation to precision poverty relief strategy.
Motivations of volunteers in the Transcribe Sheng project: A grounded theory approach
Authors: Zhang Xuanhui , Song Shijie , Zhao Yuxiang (Chris) , Zhu Qinghua
Published: February 2019

With an increasing interest in leveraging crowdsourcing in GLAMs (Galleries, Libraries, Archives, and Museums) projects, there is a growing trend within the digital humanities field to develop various platforms and tools that outsource the traditionally knowledge‐intensive tasks to the mass volunteers. However, such kind of projects usually entail a greater level of time, effort, and intellectual input from the public. In such case, what motivates volunteers remains little studied and poorly understood. To better understand volunteers' motivations and how they may benefit from their participation, we conducted interviews on volunteers in the Transcribe Sheng project, a crowdsourcing project in digital humanities domain in China. Grounded theory is employed to investigate the motivations from the interview data. The preliminary findings show that volunteers are motivated by a complex framework involving external factors, cognitive value, emotional perception, and task driven factors. Based on the qualitative analysis, this study proposes a preliminary theoretical framework to understand volunteers' motivations, which may also yield practical implications on digital humanity practices.

Do administrative roles affect professors' research?
Authors: Zhao Yuehua , Lou Wen
Published: February 2019

This study quantitatively investigated whether the research performance of academic administrators (leaders) was affected by their administrative services. We examined the quantity of 111 professors' publications and citations in the Web of Science including 90 deans and 21 university presidents, from 26 universities. To compare the effect on their research performances by their administrative roles, we proposed four periods: the pre‐position period, the latest position period, the reference period, and the in‐position period. Statistical methods were applied and suggested that administrative services have strongly affected academic leaders' research performances.
Collaboration matters: Faculty hiring in information school
Authors: Zuo Zhiya , Zhao Kang
Published: February 2019

Successful hiring decisions are important for both academic institutions and individual faculty members. While factors including institutional prestige and gender are shown to affect faculty hiring outcome, there is a lack of study on whether and how research collaboration helps. We aimed at bridging this gap with a hand‐curated dataset of 81 junior faculty members from 27 information schools. Specifically, we analysed the effect of advisors and collaborators on faculty placement, controlling for a candidate's h‐index, gender, prestige of degree‐granting institution, and position openings. We found that the median of collaborator h‐indices has a significant and positive effect on the prestige of the institution that hires a faculty. PhD graduates who have co‐authored with high‐impact researchers (other than advisors) are more likely to find faculty positions in better ranked institutions. This reveals an implicit hiring decision‐making factor that encourages young researchers to actively seek collaboration opportunities with well‐established scholars to secure a good faculty job in the future.
On the Adherence of Chemically Deposited CdS Films to Common Inorganic Substrates: Effect of Cd2+ Concentration in Solution, Substrate Surface Chemistry, and Reaction Temperature

Published: February 2019

The bad adherence to the substrate of chemical‐solution‐deposited chalcogenide films in alkaline solution is a current technological problem. However, this issue is belittled since is commonly solved by employing pre‐sensitized substrates or by empirically changing the deposition parameters until “finding” the “proper” chemical formulation. For these reasons, the issue of the adherence has not been previously studied. The present research aims to properly discuss the issue of adherence by taking as example CdS. As a substrate, we used float glass sheets to take advantage of the surface duality of this interesting flat glass (different tin content). It was found that both the surface chemical composition of the substrate and the concentration of Cd2+ in the reaction solution play important roles in the adherence of the CdS thin films; an important effect of temperature was also found. The results were also consistent for indium tin oxide and silicon wafer surfaces. We propose a general surface reaction scheme which considers both the surface reactive sites and the hidroxo–cadmium–thiourea complexes of the reaction solution, as well as the formation of a surface intermediate entity which dissociates into a CdS molecule bonded to the surface and byproducts. The adherence depends on the quantity of surface intermediate entities formed, and therefore, the conditions that promote their formation contribute to the adherence: high reagent concentration, high‐reactive surface sites, and low reaction temperature.

Coumarin is a bio‐organic compound which exists in some plants. Coumarin by its own or its derivatives are important compounds in the medicinal chemistry, agrochemistry fragrance and food chemistry. Bis(4‐hydroxycoumarin) derivatives are the most famous species of these compounds. Also, pyrano[3,2‐c]chromene‐3‐carbonitrile derivatives which contain a moiety of 4‐hydroxycoumarin have a wide range of biological activities. Taurine, the semi‐essential β‐amino acid in the organs of living creatures especially human and animals, is used as a green bio‐organic catalyst to promote the formation of biscoumarin and pyrano[3,2‐c]chromene‐3‐carbonitrile derivatives via a Knoevenagel‐Micheal reaction in aqueous media. Using this method, the requested products are obtained in high yields during acceptable reaction times and the catalyst can be recycled with high efficiency. In fact, in this study, a bio‐organic reagent is used as the catalyst to promote the synthesis of bioactive compounds in the greenest conditions possible.

Isomeric 4,5‐dihydro‐2‐[(cymantrenylmethyl)thio]thiazole (1) and 3‐(cymantrenylmethyl)‐1,3‐thioazolidine‐2‐thione (2) were synthesized and photochemical behavior and spectral characteristics of tricarbonyl and dicarbonyl complexes were studied. Irradiation of compounds 1 and 2 results in the formation of stable chelates due to coordination of manganese to the donor nitrogen and sulfur atoms of the thiazolidine substituent. Photolysis is accompanied with a colour change and the corresponding changes in the UV/Vis spectra depending on the solvent used. In the presence of CO, the dicarbonyl chelates enter the dark reaction to give the parent tricarbonyl complexes thus forming intermolecular photochromic systems. Photolysis of the dicarbonyl chelate 5 gives the isomeric chelate 6, which in the course of the dark isomerization transforms into complex 5. Chelates 5 and 6 form an intramolecular photochromic pair.

Improving the framework titanium (Ti) of titanium silicalite‐1 (TS‐1) zeolites and creating inter‐crystalline mesoporosity are two ways to enhance the catalytic properties of TS‐1 for hydroxylation of phenol. Most researches only used one of the ways. In this study, we successfully synthesized of hierarchical Titanium‐Rich (Ti‐rich) TS‐1. Ti‐rich TS‐1 was synthesized in the presence of ammonium carbonate ((NH4)2CO3). The framework Ti content of TS‐1 zeolites synthesized by different content of (NH4)2CO3 was studied by X‐ray fluorescence (XRF), Fourier transform infrared spectra (FTIR) and ultraviolet visible spectra, the framework Ti content was significantly increased by using (NH4)2CO3 as crystallization‐mediating agent. The synthesized samples were evaluated in hydroxylation of phenol. When the molar ratio of ammonium carbonate and tetraethyl orthosilicate in the synthesis gel was 0.2, the molar ratio of Si/Ti reached 34.43 and the Ti‐rich TS‐1 shows the optimum catalytic activity in hydroxylation of phenol. The post‐modification with aqueous solution of tetrapropylammonium hydroxide (TPAOH) was used to further improve the diffusion property. Compared with the parent TS‐1, the secondary pore volume was all increased. The developed hierarchical Ti‐rich TS‐1 zeolites were also assessed in hydroxylation of phenol. It was confirmed that hierarchical Ti‐rich titanium silicalite‐1 zeolites can improve the catalytic activity in phenol conversion considerably.

A new class of bridged alkyl ionic liquids has been successfully developed and they are shown to be efficient catalysts for the synthesis of a wide range of densely functionalized spiro[4H‐pyran‐3,3′‐oxindole] derivatives. With only 1 mol% catalyst, all the reactions underwent smoothly in aqueous ethanol solution at ambient temperature and afforded the corresponding products in good to excellent yields within a short reaction time. This is a simple and green protocol with significant advantages such as the use of environmentally friendly solvent, mild conditions, easy work up, no chromatographic separation, and applicability for large‐scale synthesis. The catalyst could be reused eight times at least.

In pursuit of neuroprotective and antimicrobial agents, a series of 1,2,4‐triazolo[3,4‐b]1,3,4‐thiadiazole incorporated thieno[2,3‐d]pyrimidine derivatives 10 a‐l has been designed, synthesized. The final target compounds were screened for neuroprotective, neurotoxic and antibacterial activities. The compounds derived from 4‐methylphenyl (10 a) and 4‐nitrophenyl (10 c) have showed good neuroprotective activity against H2O2 induced PC12 cell death at respective EC50 values of 10.44, 14.12 μg/mL. However 10 b and 10 k showed superior neurotoxic effects than rest of the compounds with respective CC50 values of 100.16, 120 μg/mL. Potent antibacterial activity was shown by 10 f (R=‐Me, R2=‐OMe), 10 h (R=‐Me, R2=‐Cl) against the four bacterial pathogens such as S.aureus, B.subtilis, E.coli and P.aeruginosa at low minimum inhibitory concentration (MIC) range. Further, in silico docking studies were performed for all the synthesized compounds with C(30) carotenoid dehydrosqualene synthase, Gyrase A and LpxC bacterial proteins. Interestingly, 10 f, 10 h showed good binding affinities with target proteins and these results are in good compliance with the in vitro activity profile data.
