A 3×3×3 factorial design, N=135, is used to evaluate the effects of three conditions of feedback (zero, low extrinsic, and high extrinsic), three conditions of response pattern restriction (no restriction dictated, restriction to three patterns, restriction to one pattern), and three levels of repetitive-figure manipulation diversity determined by scores on Torrance Tests of Creative Thinking, Form A, Activity III: repetitive parallel lines. The experimental task was to turn nine circularly arranged knobs repetitively in a white visual, broadband audio environment over three 6-minute periods separated by rest pauses. O'Brien (1976) found significant differences for measures of response variability including pattern changing activity, pattern shifting, error factors, and other measures. An extended ad hoc analysis of that exploratory study is accomplished in which a comparison of percent common patterns emitted evidences that Ss who score differently on the pretest perform with different degrees of uniqueness when they are restricted to repetition of previous patterns, but not when they are free to vary types of patterns emitted. Also, comparison of initial trials indicates that high pretest scorers are more likely to begin the task with rarer patterns, low scorers use more common patterns, and intermediate scorers fall in between.

Purpose This exploratory study stems from research conducted between 2015–2018 focussing on dementia-friendly design (DFD) in hospitals (Grey T et al. 2018). Specifically, this study focusses on facilities management (FM) staff in Irish hospitals to gain a preliminary understanding of the level of knowledge and engagement of FM in the implementation of dementia-friendly hospital (DFH) design. Design/methodology/approach A mixed-methods approach based on a series of ad hoc semi-structured interviews, and an online survey. The aims were, namely, assess the extent of FM engagement in hospital works; measure the level of awareness regarding DFD; and identify facilitators and barriers to DFD in hospital settings. Participants (74) comprised FM staff in 35 Irish acute care hospitals. The research findings are based on thematic analysis of ad hoc semi-structured interviews (participants, n = 4) and survey responses (participants, n = 13). Findings While FM staff reported to possess important knowledge for building DFH, they also mentioned a lack of engagement of FM in design processes and hospital works. Practical implications The research has gained insight into the role of FM in promoting a dementia-friendly approach. Lack of or poor engagement of FM in design processes and hospital works means not fully tapping into rich expertise that would be invaluable in the development, implementation and maintenance of DFH. Universal design is a key driver for facilitating their engagement in the design, implementation and maintenance of DFH environments. Originality/value This is the first study exploring the role of FM in supporting a DFD approach in acute care hospitals.

Type 3

This exploratory study examines technically educated middle managers performing ad hoc projects in flat organizations and develops a typology for examining the behavioral patterns associated with their effectiveness. Initial findings indicate the greatest success was achieved by “Type 1” managers (the Leaders) who were able to integrate collaborative selling skills and technical expertise within a web of both formal and informal interactions. Moderate success accrued to “Type 2” managers (the Learners) who used collaborative selling skills to develop social networks that allowed them to expand their own technical expertise. “Type 3” managers (the Leapers) primarily relied upon technical expertise as the tool for interacting with others and enjoyed only modest success. Although “Type 4” managers (the Laggards) had the requisite technical knowledge base, they were the least successful because their lack of collaborative selling skills made it difficult to utilize a compensatory social network. Suggestions are provided for leaders seeking to leverage and direct the abilities of key staff.

Do So

The selection of variables in a given experiment is crucial, since it is the theoretical foundation that guides how data should be collected and analyzed. However, selecting variables is an intricate activity, especially considering areas such as Software Engineering and Education, whose studies should also consider human-related variables in the design. In this scenario, we aim to investigate how a support mechanism helps in the variables selection activity of the experiment process. To do so, we conducted a preliminary study on the use of an experimental framework composed of a catalog of variables. We explored the domain of the integration of software testing into programming education. Participants were divided into two groups (ad hoc and framework support) and asked to select variables for a given experiment goal. We analyzed the results by identifying threats to validity in their experimental design drafts. Results show a significant number of threats of type inadequate explication of constructs for both groups. Nonetheless, the framework helped to increase the clarity of concepts selected as variables. The cause of most raised threats, even with the framework support, was an inaccuracy in selecting the values of such variables (i.e. treatments and fixed values).

Study Context

Students’ possibilities to interact with peers have reduced drastically during the emergency transition to online teaching due to the Covid-19 pandemic. Students report on decreased motivation and other study related issues; hence, there is a need to better understand the effects of decreased interaction. The aim of the present exploratory study was to document changes in student networks, in relation to perceptions of connectedness, study outcome and well-being in two different settings. An ad hoc online survey (n = 97) was distributed among students from one research-intensive and one teaching-intensive university where many students commute. Results showed that student social networks defoliated from the outside-in and left students with an inner circle of students they shared multiplex relations with. Students who had lost more working and multiplex relations also reported a decline in well-being. The main contribution of this study is the visualization of how networks became fragmented, and how the experience of this differed depending on type of study context. These findings may have implications for a post-Covid organisation of higher education.

The Impact

Patient safety and quality efforts recently began to emphasize patient and family engagement in medical decision making. With measures primarily focused on satisfaction, challenges exist around understanding the impact of engagement on patient outcomes. Research is needed to understand the role of patient/family in safety and quality across clinical environments. The current exploratory study uses observations, ad hoc interviews, and questionnaires to capture the perspective of clinicians and staff on a Medical Intensive Care Unit regarding presence and engagement of families in patient care. Findings suggest that reported roles go beyond emotional support and further investigation is needed to explore the role of families in patient care from the safety and quality perspective.

One of the most important promises of the relational data model has been that it frees the decision maker, the manager, from the necessity of resorting to an intermediary, the programmer, in retrieving information from the organization’s database in response to unanticipated needs. That promise is founded on the availability of very high-level relational query languages such as SQL. Unfortunately, the current specification of the SQL standard fails to support users adequately in formulating complex queries involving set comparison that tend to arise in on-line analytical processing (OLAP) situations. As pointed out by Rao et al. (1996): “SQL’s syntax is too restricted to express quantified queries. While SQL allows subqueries to form sets, the relationships that can be expressed over sets are limited, and must be written in awkward and complicated ways.” This chapter presents a systematic approach for teaching users how to formulate in SQL complex set comparison queries encountered in ad-hoc decision-making scenarios.

Conversational Interactions

On Twitter, a range of discourse networks may be extracted showing different types of conversational interactions. While the attention is often on what is trending and large-size high-interactive social graphs, many extracted networks are self-loops and small-group discourse networks based on ad hoc narrowcast conversations. In this exploratory study of microblogging messaging on Twitter, the focus is on microblogging conversations that result in self-loops (self-to-self conversations, individuals microblogging to themselves) and small-group graphs and motifs (one-to-few or few-to-few conversations). This work proposes and tests hypotheses about the various types of seeding #hashtags and keywords that result in different types of ad hoc microblogging microchat network graphs on Twitter.
