The Impact

GE performed an ultrasonic phased-array (USCD DUO) in-line inspection (ILI) survey of a 24-inch and 26-inch products pipeline. The primary purpose of this ILI survey was to detect and characterize stress corrosion cracking (SCC). A dig verification was subsequently performed throughout 2008 in order to establish a higher level of confidence in the detection and depth-sizing capabilities of this technology. Presented herein is an overview of the USCD technology and experience, the method used for validating the ILI survey results, enhancements to the ILI data analysis, and the impact on managing the integrity of the subject line section.

The Impact

PurposeIn most higher education institutions, information literacy (IL) instruction is usually considered the purview of librarians, not disciplinary faculty. However, a small but growing body of research indicates that students learn the research process best when these skills are taught in the context of a course or a discipline. For this reason, teaching faculty should share ownership of IL instruction — but how? In this case study, community college librarians explain how they successfully trained faculty to integrate IL into their English Composition courses and teach IL independently.Design/methodology/approachUsing a multimethods approach, the investigators draw on faculty interviews, student surveys, and content analysis of student essays to evaluate the impact of faculty-led IL instruction on student learning after one semester.FindingsFaculty reported that their instruction of IL was improved, and students work better as a result of their collaboration with the librarians. Compared to previous semesters, faculty perceived gains in terms of students’ ability to synthesize and cite evidence in their writing. Student survey results indicate perceived gains in their IL skills, but an assessment of their written work reveals a discrepancy between this perception and the actual application of these skills.Research limitations/implicationsBecause there is no control group, no conclusions can be drawn as to whether faculty-led IL instruction is as effective as librarian-led IL instruction or whether students’ academic performance improves due to faculty teaching IL. However, the purpose of this study is primarily descriptive. It addresses how other libraries may create a culture of shared ownership of IL instruction on their campuses.Practical implicationsThis study offers an alternative model to library instruction and suggests ways instruction librarians can prioritize their outreach and instructional efforts to maximize impact on student learning.Originality/valueWhile much has been written about how librarians can improve IL instruction, few studies mention the role of faculty. This case study starts the conversation.

The contactless coalescence of a droplet is of paramount importance for physical and industrial applications. This paper describes a coalescence method to be used mid-air via acoustic levitation using an ultrasonic phased array system. Acoustic levitation using ultrasonic phased arrays provides promising lab-on-a-drop applications, such as transportation, coalescence, mixing, separation, evaporation, and extraction in a continuous operation. The mechanism of droplet coalescence in mid-air may be better understood by experimentally and numerically exploring the droplet dynamics immediately before the coalescence. In this study, water droplets were experimentally levitated, transported, and coalesced by controlled acoustic fields. We observed that the edges of droplets deformed and attracted each other immediately before the coalescence. Through image processing, the radii of curvature of the droplets were quantified and the pressure difference between the inside and outside a droplet was simulated to obtain the pressure and velocity information on the droplet’s surface. The results revealed that the sound pressure acting on the droplet clearly decreased before the impact of the droplets. This pressure on the droplets was quantitatively analyzed from the experimental data. Our experimental and numerical results provide deeper physical insights into contactless droplet manipulation for futuristic lab-on-a-drop applications.

The Impact

Since taking off as an industry in Sweden in the 1980s, contract archaeology has changed not only the role of field archaeologists but also that of museums and the formation of collections. This paper discusses some of the effects of the commercialization of archaeological services through a case study of past and present collection practices. Data records are compared from three different archaeological investigations at the site Nya Lödöse (1473-1621) in Gothenburg. Each excavation represents a particular era in archaeological practice. The data are used to compare and analyse collecting practices within contemporary contract archaeology. Separately, a survey among contract archaeology units examines the implementation of legislative guidelines and day-to-day practices and suggests several causes for anomalies in the selection and discarding of finds in the case study. Combined, the findings of the case study and the survey results, suggest that contract archaeology leaves a specific imprint on collections in archaeological museums, impacting their compilation, and therefore influencing future research as well as the experience of the public.

The Impact

The QUILT programme was designed and delivered on the basis of a major FE sector survey of 15,000 college staff and a series of consultation events during 1996. The survey results were included in FEDA's submission for funding for the QUILT programme to the FEFC. The events, to which a senior manager and the member of staff responsible for IT in every sector college were invited, took place in every English region and in Wales. Theseestablished training and other needs, the extent of technological readiness in colleges, and preferred training methods. QUILT was launched in Wales in 1996 and in England during the following year. Its design has been adjusted to account for a follow-up survey in 1998 and an impact study in 1999. Both of these (like the original survey report) were unpublished FEDA documents; data from them was used in internal reports to the FEFC and its Information and Learning Technology Committee (FEILTC). Other evidence for change was provided by (for example) comments from delegates at events and from members of the FEILTC. Subsequent initiatives also accounted for adjustments to the programme to avoid duplication and to maximize synergy.DOI:10.1080/0968776000080308

The article discusses an analysis of employee survey results in the context of the objectives of the personnel function in an organisation. In the introduction there are presented theoretical assumptions concerning the approach to the evaluation process relating to the personnel audit. This is the approach used in employee satisfaction assessment programs. The example of such an approach is the one presented in the text, the annual program of the analysis of expectations, motivation and employee satisfaction for huge Scandinavian trade network. Findings described in the text refer to the impact of employee opinions on personnel practices undertaken to enhance the effectiveness of HRM in the studied company. The main conclusions (priorities for managers) of such an audit include actions to improve efficiency in terms of: working conditions, leadership, and promoted values, and job content and development.

In Bangladesh, the lockdown has been started officially from 26th March 2020 which is actually the most important time for harvesting and summer stocking in the pond. The whole aquaculture production system is now hampering due to pandemic COVID-19 and the value chain in this sector is quite vulnerable. I conducted a wireless survey through cell phone collected information from different stakeholders of different agro-ecological zones of Bangladesh to assess the impact of the pandemic situations in the aquaculture sector. Survey results revealed that pandemic COVID-19 has been affected in different areas of the aquaculture sector including reduction of consumption, export order cancellation, reduction in price, delay in summer stocking, lack of technical support, and transport crisis.

The Impact

In higher education institutions, web surveys are frequently used for educational, research, and administrative purposes. One of the consequences of this is increasing oversurveying of higher education students, leading to low response rates. This naturally has important implications for the validity of web survey results. Consequently, we set up a methodological experiment at Tilburg University, the Netherlands, whereby the total student population was invited to participate in a web survey in order to investigate which features of contact design can positively influence web survey participation. We particularly focus on subject line content, the communication of deadlines and their timing, as well as the delays between contact moments. The results reveal that students were more likely to respond to a web survey invitation when the subject line is written in the national language in multilingual contexts. Furthermore, although the findings did not indicate an advantage of using a deadline, they also suggested that if a deadline is to be used, a longer deadline might be more beneficial.

The Impact

This work presents a multi-course project-based learning (MPL) approach implemented using two electrical engineering (EE) interdisciplinary undergraduate courses at Qatar University. Implementing an MPL approach helps in the development of critical thinking and collaborative decision-making skills. The attainment of these skills is also the outcome of education for sustainable development (ESD); the skills help students acquire the knowledge, attitudes, and values necessary to shape a sustainable future. The participating students’ worked on a design project, which was used to assess the fulfillment of a set of student learning outcomes (SLOs), focusing on engineering soft skills and project management skills. The skills include the ability to communicate effectively, to work collaboratively in a team, to think both critically and creatively, and to manage projects efficiently with realistic constraints and standards. The challenges of implementing the MPL method are the organization of pedagogical activities that are planned for each of the courses involved, the coordination of the materials delivered by each course, and the supervision of around 90 students per year performing the MPL method. The experience of MPL deployment in the EE program was rated using student surveys. It was assumed that the MPL approach would be beneficial to the students based on the instructors’ and students’ feedback from the same courses in previous years. This was verified using chi-square statistics of the survey results. The implementation of the MPL also helped in increasing the average marks scored by the students in the design project. Some interesting feedback, statistical analyses, and improvement actions are reported for future upgrades. This work also contributes to the MPL pragmatic body of knowledge by exploring a successful initiative and its outcomes, which can help in attaining the skills needed for ESD.
