The multiplication principle (MP) is a fundamental aspect of combinatorial enumeration, serving as an effective tool for solving counting problems and underlying many key combinatorial formulas. In this study, the authors used guided reinvention to investigate 2 undergraduate students' reasoning about the MP, and they sought to answer the following research questions: How do students come to understand and make sense of the MP? Specifically, while a pair of students reinvented a statement of the MP, how did they attend to and reason about key mathematical features of the MP? The students participated in a paired 8-session teaching experiment during which they progressed from a nascent to a sophisticated statement of the MP. Two key mathematical features emerged for the students through this process, including independence and distinct composite outcomes, and we discuss ways in which these ideas informed the students' reinvention of the statement. In addition, we present potential implications and directions for future research.

The use of Facebook in everyday life has become widespread all around the world regardless of countries and cultures. The largest group of Facebook users consists of young people, particularly university students. This study investigated the attitudes of university students toward Facebook, their major reasons for using this social media application in everyday life, and the factors affecting the types of desired relationships with Facebook friends. A survey consisting of 63 items about demographics of participants and their preferences for the use of Facebook was administered to collect data. The sample of the study included 924 undergraduate students from a large public university in North Cyprus. A number of descriptive and inferential statistical techniques were employed to analyze data in relation to the research questions. Results suggested that the students generally had positive attitudes toward Facebook, although there were certain differences in terms of demographics. The primary reason for using Facebook was interpersonal communications with close friends. The most powerful factor affecting the types of relationships in Facebook was perceived quality of communication and/or socialization. Along with the other findings, implications of the results for future research were discussed.

A Review of: Thomas, S., Tewell, E., & Wilson, G. (2017). Where students start and what they do when they get stuck: A qualitative inquiry into academic information-seeking and help-seeking practices. Journal of Academic Librarianship, 43(3), 224-231. http://dx.doi.org/10.1016/j.acalib.2017.02.016 Abstract Objective – To investigate where students start their research, what resources they use, and when they may consult with a librarian. Design – Ethnographic, semi-structured interviews. Setting – A mid-sized, private university located in the northeastern United States of America. Subjects – 15 students; 7 undergraduate students and 8 graduate students. Methods – Researchers gathered data as part of a larger ethnographic study conducted at the university. Interview participants were selected from among respondents to an email survey sent to all university students. Interview participants were purposefully selected to represent the student population with regards to their status (undergraduate or graduate), progress through their programs, and their majors. The semi-structured interviews focused primarily on how students approached the beginning stages of research and the types of resources used. The authors read each interview transcript to identify possible research questions, then re-read transcripts to identify codes and potential themes related to the selected research questions. Finally, they analyzed the transcripts to determine where essential themes and keywords appeared, while highlighting relevant passages and finalizing themes. Main Results – Students were more likely to seek research help from faculty members and their peers than from librarians. Graduate student interviewees were more likely to report consulting with librarians than undergraduate students. Interview themes suggest that students may not consult with librarians because they do not perceive librarians as having the subject knowledge or “insider” status (p. 227) of their professors and peers. Few students articulated an understanding of the expertise librarians could bring to a research project. When starting a research project, students were more likely to report beginning with library databases than they were Google or other open web sources. While many students also shared that they used multiple different resources in their initial stages, most also reported that they ultimately narrowed their search focus to a specific database. Students also discussed struggling with their database searching. Conclusion – The authors suggest that future research should focus on understanding the types of resources that faculty members recommend to their students, which could inform how librarians approach their work with students. Additional research related to how faculty members and students perceive librarians may also clarify the role these groups expect librarians to fill during the research process. Although results cannot be generalized to all student populations, the authors call for librarians to further explore assumptions about how students begin their research and the work academic librarians do to support students’ natural behaviours and preferences.

[This Proceedings paper was revised and published in the 2019 issue of the Journal of Information Technology Education: Innovations in Practice, Volume 18.] Aim/Purpose: The study examined types of errors made by novice programmers in different Java concepts with students of different ability levels in programming as well as the perceived causes of such errors. Background: To improve code writing and debugging skills, efforts have been made to taxonomize programming errors and their causes. However, most of the studies employed omnibus approaches, i.e. without consideration of different programing concepts and ability levels of the trainee programmers. Such concepts and ability specific errors identification and classifications are needed to advance appropriate intervention strategy. Methodology: A sequential exploratory mixed method design was adopted. The sample was an intact class of 124 Computer Science and Engineering undergraduate students grouped into three achievement levels based on first semester performance in a Java programming course. The submitted codes in the course of second semester exercises were analyzed for possible errors, categorized and grouped across achievement level. The resulting data were analyzed using descriptive statistics as well as Pearson product correlation coefficient. Qualitative analyses through interviews and focused group discussion (FGD) were also employed to identify reasons for the committed errors. Contribution:The study provides a useful concept-based and achievement level specific error log for the teaching of Java programming for beginners. Findings: The results identified 598 errors with Missing symbols (33%) and Invalid symbols (12%) constituting the highest and least committed errors respec-tively. Method and Classes concept houses the highest number of errors (36%) followed by Other Object Concepts (34%), Decision Making (29%), and Looping (10%). Similar error types were found across ability levels. A significant relationship was found between missing symbols and each of Invalid symbols and Inappropriate Naming. Errors made in Methods and Classes were also found to significantly predict that of Other Object concepts. Recommendations for Practitioners: To promote better classroom practice in the teaching of Java programming, findings for the study suggests instructions to students should be based on achievement level. In addition to this, learning Java programming should be done with an unintelligent editor. Recommendations for Researchers: Research could examine logic or semantic errors among novice programmers as the errors analyzed in this study focus mainly on syntactic ones. Impact on Society: The digital age is code-driven, thus error analysis in programming instruction will enhance programming ability, which will ultimately transform novice programmers into experts, particularly in developing countries where most of the software in use is imported. Future Research: Researchers could look beyond novice or beginner programmers as codes written by intermediate or even advanced programmers are still not often completely error free.

The purpose of this study was to explore recreational prescription drug use among undergraduate students. Although anecdotal accounts on this subject abound, empirical research is extremely limited. Data from a survey of a random sample of 734 students at a large public research university in the Northeast were examined. Results indicate that a substantial proportion of students reported having used prescription drugs for recreational purposes in the year prior to survey administration. Recreational prescription drug use was positively associated with the use of other substances including alcohol. Recreational prescription drug users were also more likely than other drug users to report negative consequences as a result of their drug use. Implications for future research and for student affairs are discussed.

SUMMARY As the scope of the audit continues to broaden (Cohen, Krishnamoorthy, and Wright 2017), research questions in management control and internal control are beginning to overlap. Even so, there is little overlap between these fields in terms of published research to date. The purpose of this paper is to take a step in bridging the gap between the management control and the internal control literatures. We survey relevant findings from the extant management control literature published between 2003 and 2016 on dysfunctional behavior and the ways in which it might be mitigated. We then use the fraud triangle as an organizing framework to consider how the management control literature might help to address audit risk factors identified in SAS 99/AU SEC 316 (AICPA 2002). The outcome of our analysis is meant to identify and classify the extant management control literature of relevance to research on internal control in a manner that researchers new to the management control literature will find accessible. We conclude with a set of future research opportunities that can help to broaden the scope of current research in internal control.

ObjectivesThe aim of this study is to collect the perspectives and values of people affected by amyotrophic lateral sclerosis (ALS) and their carers to offer clinicians, researchers and policymakers aspects which are precious in prioritising future research questions and reshaping care service organisations in a participatory approach.Design and settingCohort study using ALS Umbria, the electronic database in Italy.ParticipantsEleven patients and 33 carers who agreed to participate in the study were divided into six focus groups by ‘status’ (patient or carer) and by four severity levels of ‘burden of disease’.MethodsA semiquantitative analysis was undertaken. Each recorded group discussion was transcribed into text file and independently read by two psychologists and two ALS specialists to blindly identify needs, emotions and medical issues, which are the key semantic meanings expressed. Any disagreement in interpretation was resolved through consultation among authors.ResultsCarers pronounced significantly more words related to patient’s disease burden they cared. 40% of subjects expressed the need for ‘assistance’, regardless of the disease burden. ‘Anger’ alone represented more than 1/4 of all expressed emotions and was more common in patients than in carers (73% vs 36%, p=0.077). The most frequent medical issue expressed by 1/3 of participants was ‘difficulty in communication’.ConclusionThis study has given voice to the expectations of those affected by the burden of ALS. ‘Welfare assistance’, ‘anger management’ and resolution of ‘difficulties in communication’ represent issues that need to be analysed in a common prioritised research agenda with sensible and shared outcome measures to implement patient-centred medicine.

AbstractThe application of artificial intelligence (AI) in hospitals yields many advantages but also confronts healthcare with ethical questions and challenges. While various disciplines have conducted specific research on the ethical considerations of AI in hospitals, the literature still requires a holistic overview. By conducting a systematic discourse approach highlighted by expert interviews with healthcare specialists, we identified the status quo of interdisciplinary research in academia on ethical considerations and dimensions of AI in hospitals. We found 15 fundamental manuscripts by constructing a citation network for the ethical discourse, and we extracted actionable principles and their relationships. We provide an agenda to guide academia, framed under the principles of biomedical ethics. We provide an understanding of the current ethical discourse of AI in clinical environments, identify where further research is pressingly needed, and discuss additional research questions that should be addressed. We also guide practitioners to acknowledge AI-related benefits in hospitals and to understand the related ethical concerns.

This study examines students’ perceptions of an open pedagogy experiment in which they created their own textbook for an undergraduate public health course. The lead author’s primary motivation for developing this assignment was the high cost associated with the traditional textbooks that were otherwise needed to cover the breadth of subject matter in the course. The resulting open textbook included 19 chapters, covering all the required components of the course, and the final version was published in a statewide open educational resource repository. Students provided feedback about this undertaking by way of an end-of-term survey. The results showed high percentages of students who associated the textbook creation project with greater engagement and satisfaction than the passive use of traditional textbooks. Students also reported their perception of a learning benefit related to the creation of course content. Pedagogical implications of this study are discussed, and future research questions are proposed.

AbstractAgility is an important skill for both attackers and defenders in invasion sports such as codes of football. On the sporting field, agility requires reacting to a stimulus, often presented by an opponent’s movement, before a change of direction or speed. There is a plethora of research that examines the movement component of agility in isolation, which is described as change-of-direction (COD) ability, and this is thought to underpin agility performance. This opinion article proposes that COD ability should not be researched as the only or primary outcome measure when the objective is to inform agility performance in invasion sports. It is argued that pre-planned COD movements and tests lack ecological validity because they lack perception-action coupling and involve movement out of context from the game. The movement techniques and strength qualities required for the performance of COD tests can be quite different to those required for agility. It is suggested that COD tests can be applied to sports that involve pre-planned COD movements, but researchers should endeavour to use agility tests when studying invasion sports. Some new methods for assessing one-on-one agility contests are reported as potentially valuable for future research, and examples of research questions are provided.

The need for green business practices and green innovations underscores a growing recognition that climate change is now an existential threat not just to population health but also to the survival of businesses that are unable to embrace green practices with a sense of urgency. This paper contributes to the literature on market violence as an inhibitor of green innovations for sustainable waste management to curb the unneeded health effects of wastes in Africa. Our purpose is to problematize received wisdom, unquestioned assumptions, and incorrect diagnosis of the sources and health consequences of various forms of wastes in Africa. Much of the discourse on this issue remains ahistorical, and that risks leaving aside a vital question of exploitative extraction. By including this ‘out-of-the-box’ explanation through major case references, we are able to shed light on the critical issues that have hitherto received limited attention, thus enabling us to propose useful research questions for future enquiries. We propose a framework that delineates the structural composition of costs imposed by market violence that ranges from extraction to e-waste disposal. We advocate for the engineering of policies that create conditions for doing more with less resources, eliminating waste, and recycling as crucial steps in creating sustainable waste management innovations. Additionally, we highlight a set of fundamental issues regarding enablers and inhibitors of sustainable innovations and policies for waste management worth considering for future research. These include programmed obsolescence, irresponsible extraction, production, and consumption, all seen through the theoretical lens of market violence.
