Integrating Evidence-based Learning in Engineering and Computer Science Gateway Courses

Gateway Courses generally refers to the courses that are crucial for students to progress through their chosen majors. The successful completion of the gateway courses are necessary because these courses are mostly the prerequisites of other courses in the majors. However, many types of attritions in the STEM gateway courses lead to high failure rates. To tackle this challenge, a team of STEM faculty members at Alabama A&M University (AAMU), a land-granted HBCU, has redesigned the gateway courses in computer science, mechanical engineering and construction management by replacing the lecture-dominated practices with evidence-based teaching pedagogies. In this study, two evidence-based pedagogies, problem-based learning and project-based learning have been implemented and tested in different levels of STEM gateway courses in the last three years. An assessment framework has been established to analyze the effect of the implemented pedagogies. Continuous assessment data have been collected and compared with the baseline data collected in the lecture-dominated same courses. Student surveys have been conducted and analyzed as well. Our study showed the evidence-based teaching practices fostered both the students’ cognitive and non-cognitive skills. The DFW rates were also decreased in all semesters in all the targeted STEM gateway courses in this study. Based upon the success and lessons learned, our future work will expand and test the interventions in more gateway courses across STEM disciplines at AAMU, to enhance the minority student success, retention and graduation.
A review of Rey's strategies for detecting malingered neuropsychological impairment

Abstract Andre Rey was a pioneer in clinical psychology, child clinical psychology, and neuropsychology. His contributions to the understanding of brain-behavior relationships were novel, creative, and highly regarded. Rey developed many eponymous tests and procedures. Three are relatively well known in American neuropsychological literature as “tests of malingering”: The Rey 15-Item Memory Test (RMT), the Rey Word Recognition Test (WRT), and the Rey Dot Counting Test (DCT), referred to collectively in this paper as the “Rey malingering tests. ” By citing his original work, this article reports Rey's method of assessing the validity of clinical presentation, his instructional sets for each test, and his process of interpreting test results. Additionally, this article reviews published research regarding the efficacy of the Rey malingering tests as they have been used in thiscountry. Most instructional sets and interpretive strategies generally have not followed Rey, but have followed those represented as R.
Jurassic sedimentary mélange and associated facies, Baja California, Mexico

The Middle Jurassic Coloradito Formation of Cedros Island, Baja California, is a fine-grained flysch sequence that includes some coarse debris flow–filled channels. Sedimentary melange (olistostrome) is widespread, and is composed of sheared black argillite with megablocks of Triassic cherts (shallow-water origin? ), Paleozoic limestone, and continental sandstone derived from the north. This unit represents the earliest record of arc-continent interaction in the Baja area. The Eugenia Formation is locally present in erosional contact above the Coloradito Formation. The unit is a northerly derived channel-fill deposit, in which the lower one-third is dominated by metasedimentary detritus and first-cycle calc-alkaline volcanic detritus dominates above this. The long axes of clasts in sheared argillite of the Coloradito have orientations parallel to clast imbrication in associated conglomerate channels, suggesting shearing due to downslope sliding. Contrasting deformation styles (sheared versus open folded) of fine-grained Coloradito units may be due to abundance of smectite in the latter, allowing higher water retention and a more plastic style of deformation. Jurassic sedimentary sequences on Isla Cedros record a complex history of explosive island-arc volcanism (Gran Canon Formation), arc-continent collision (Coloradito Formation), and renewal of magmatic arc volcanism (Eugenia Formation).
What Do Shareholders Coalitions Really Want? Evidence from Italian Voting Trusts

This paper studies the effects of having multiple large shareholders who share the control of firms, by analysing a unique dataset of Italian shareholders’ agreements (voting trusts). We investigate the separation between ownership and control granted by such agreements, showing that, on average, a voting trust owning 52 per cent of the total company’s cash-flow rights is able to exercise up to 87 per cent of the total board rights; the wedge is particularly beneficial to the largest shareholder within the voting trust who is able to get the majority of board rights despite owning only a minority fraction of the company’s cash-flow rights. Then, an event-study analysis of a sample of voting trusts’ announcements is performed. The results support the “entrenchment effects” hypothesis (Stulz, 1988) linking the ownership structure and the firm value, and are consistent with the view that, in Italy, voting trust agreements are mainly aimed at both protecting controlling shareholders from hostile takeovers and entrenching incumbent management.
Generalised Euler characteristics of Selmer groups

Let E be an elliptic curve defined over a number field F, and let p ⩾ 5 be a prime. In this paper, we study the structure of the Selmer group of E, over p‐adic Lie extensions F∞/F. In particular, under certain global and local conditions on F∞ we relate the generalised Gal(F∞/F)‐Euler characteristic of Sel(E/F∞) to the generalised Euler characteristic of the Selmer group over the cyclotomic ℤp‐extension of F. This invariant generalises the classical Euler characteristic to the case when rankℤE(F) > 0. Moreover, we show that the global and local conditions on F∞ are satisfied for a large class of p‐adic Lie extensions of F.
RELATIONSHIP AMONG PARENTAL STRESS LEVEL, PUPILS’ SOCIAL COMPETENCE AND SCHOOL ADJUSTMENT IN ENUGU STATE, NIGERIA

The study investigated the relationship among parental stress level, pupils’ social competence, and school adjustment in Nsukka Local Government Education Authority (LGEA) of Enugu State, Nigeria. The study adopted a correlation survey research design. Four research questions and four null hypotheses guided the study. The population of the study comprised all 3678 primary three pupils in the 98 primary schools (1678 pupils from 51 public schools and 2000 pupils from 47 private schools) in Nsukka LGEA. A sample of 200 pupils was selected through proportionate stratified random sampling technique to make for an in-depth study. The instrument for the study was three sets of researcher designed questionnaire identified as: Parental Stress Level Questionnaire (PSLQ); Pupils’ Social Competence Scale (PSCS); and Pupils’ School Adjustment Scale (PSAS). PSLQ, PSCS and PSAS were validated by specialists. The PSLQ had parents as the respondents while PSCS and PSAS had the class teachers as the raters. Data collected were analyzed using regression analysis for hypotheses 1 and 2; and t test statistic for hypotheses 3 and 4. The major findings of the study revealed that PSL was significantly related to PSC and PSA with PSL accounting for 2.6% and 34.1 % of the variance in PSC and PSA respectively. The findings also revealed that gender had significant influence on PSC but had no significant influence on PSA. The educational implication of the findings of this study is that controlling parental stress level can engender the pupils’ development of social competence and the necessary skills to adjust well in school irrespective of gender. The researcher therefore recommended that all concerned – the government, the school, the society and the parents themselves should have a re-think on all the precursors of high parental stress level as that will go a long way in enhancing healthy parent-child interactions needed for development of social competence and proper school adjustment. The researcher further recommended that parents, teachers and other child advocates should not see gender as a barrier to pupils’ development rather they should provide equal access to environments that are conducive for every child to develop and learn.
Performing tourism: exploring the productive consumption of tourism in enclavic spaces

In this paper the interactive nature of touristic encounters in enclavic spaces is explored. Drawing on concepts of tourism as performative practice, it examines tourist experience as a form of productive consumption in which holidays are shaped by interactions with both those working in tourism and other tourists. The discussion draws on data gathered in semi-structured interviews carried out with 39 solo female tourists from the UK. The findings of this study suggest that the sexualised performances of tourism employees and of different groups of tourists in the physical, temporal and social contexts of the holiday have the power to render such spaces inclusive or exclusionary.

Evolution of the magnetic anisotropy with carrier density in hydrogenated Ga 1 − x Mn x As

The magnetic properties of (Ga,Mn)As thin films depend on both the Mn doping level and the carrier concentration. Using a post growth hydrogenation process we show that it is possible to decrease the hole density from 1.1021 cm-3 to axes, with increasing hole density and temperature. Our study concluded on a general agreement with mean-field theory predictions of the expected easy axis reversals, and of the weight of uniaxial and cubic anisotropies in this material.
Garbage Classification Based On Deep Residual Weakly Supervised Learning Model

The realization of garbage classification has become a hot topic in society, but today’s garbage processing plants use the manual pipeline sorting method for waste sorting. This kind of work method has a harsh working environment, high labor intensity, low sorting efficiency. Moreover, for the treatment of large amounts of garbage, manual sorting can only sort out a minimal part, and the vast majority of the remaining garbage can only be landfilled, which undoubtedly brings significant waste of resources and environmental pollution risks. With the application and development of deep learning technology in computer vision, it is possible to use AI technology to automatically sort waste: using cameras to take pictures of waste and then detecting the type of waste in the pictures so that the machine can automatically sort waste. This can significantly save colossal labor costs and improve waste sorting efficiency. This paper is based on deep residual weakly supervised learning ResNext series networks to classify garbage images, researches and explores AI technology for garbage classification, and contributes to the whole society is garbage classification.
A Multi-major Senior Design Experience

Engineering Technology (ET) programs focus on the hands-on approach to engineering education. To keep pace with the rapid growth of industrial technology in the area of automation and artificial intelligence, ET programs need to introduce students to cutting-edge hands-on interdisciplinary project experiences. In this paper, such a pilot project is discussed where ET students at Oklahoma State University, Stillwater, OK have been exposed to state-of-the-art autonomous vehicle technology as an interdisciplinary senior design project. The project was introduced as a competition among teams consisting of electrical engineering technology (EET), fire protection safety engineering technology (FPSET), and mechanical engineering technology (MET) students. The objective of the project was to design a vehicle that can autonomously navigate a specified course at high speed while completing an assigned mission. The learning outcomes of the project are: (1) evaluate students for their ability to think beyond the classroom education while solving an important societal problem, (2) gain experience working in an interdisciplinary team of students with diverse backgrounds, and (3) increase the synergy among the EET, FPSET, and MET programs for a future graduate degree program in Mechatronics and Robotics. It is observed that the ET students are willing to learn and adapt to the latest open source technologies in their projects, such as OpenCV for camera vision and image processing. The paper focuses on three important aspects of the project from the perspective of ET students. First, the approaches of ET students in handling cutting-edge technology as an open-ended problem. Second, approaches of the instructors to facilitate the two-semester project along with the lessons learned. Third, both the instructor and student experiences during the project. The paper also includes sample material for project specifications, milestones, feedback, and reporting procedures along with the challenges encountered by both the students and the instructors. The paper also presents the analysis of the student outcomes accessed by the instructors, student comments, and discussion on methods to increase student motivation, participation, and project evaluation. This paper will serve as a teaching aid for the instructors who are currently teaching or plan to teach senior design in the near future. Most specifically, this will help newly joined junior faculty members in planning the senior design course and adapting some of these material and reporting procedures.
It takes two to tango … but what if one can’t dance and the other doesn’t want to: a response to van de Ven et al.

The recent article by van de Ven et al. (2005) makes a valuable contribution to inclusion debates by questioning what we actually mean when we talk about integration. The authors construct a model of integration which emerges from a research project involving disabled people and those close to them. The research participants had, as the authors acknowledge, primarily motor impairments and, as a proviso, it is suggested that those people with chronic illnesses or invisible impairments may face different attitudes from others in society and may have different obstacles to overcome (p. 327). I can’t help thinking that this article highlights difficult but fundamental issues within the field of disability studies that are not being addressed. These issues centre primarily, though not exclusively, upon the position of people with learning difficulties both within the disability movement and within society more generally. One of the key findings of the research project is that both disabled and non-disabled people have a mutual responsibility towards integration. As the authors state:
First radar detection of a misocyclone in a UK tornadic storm

fully developed to an underlying urban area. Laboratory experiments would enable more controlled measurements that would complement such an observational programme. Many urban areas are too small for the boundary layer to adjust fully, so that it is important to investigate the transition from rural terrain to the urban area. Here large-eddy modelling is the crucial tool, perhaps starting by investigating how the boundary layer responds to simple changes in surface properties. New theoretical concepts are required if the urban areas are to be parametrized effectively both in the largeeddy modelling studies and NWP. Here the expertise amongst the UK community developed in studying boundary-layer flow over hills and through vegetation canopies might well provide clues. Methods for representing the average effects of vegetation on the boundary layer as 'canopies' are now reasonably well developed, and a similar approach to representing buildings within urban areas might prove fruitful. Results from these theoretical studies could suggest further large-eddy model simulations and thence further observational studies. These studies of mixing and transport in urban areas will provide the basis for studying the complex chemical transformations that control pollutants from urban sources. Clearly such an integrated programme of work requires careful co-ordination and planning. UWERN is the ideal vehicle to perform this task.
Comment on Reid Ewing and Fang Rong's “The impact of urban form on U.S. residential energy use”

Abstract Using a complicated stepped analysis, Ewing and Rong study the impact of sprawl on household energy use. They argue that dispersed land use brings about larger houses and more detached units, which consume more energy than the smaller houses and attached units typical of more compact communities. This comment suggests that their conclusions are intuitive and obvious, but that their complex methodology linking three unrelated data sets renders their quantitative conclusions suspect. Further, a simple engineering analysis can show more meaningful results, sprawl is more likely to affect energy use through increased vehicle miles traveled than house size or type, and household energy use can be mitigated by increasing the efficiency of the building envelope, heating/cooling system, appliances, and lighting. Still, combining the effects of compact urban development with the effects of energy‐efficient vehicles and housing unit design can be a real winner in our quest for more energy‐efficient communities.
Mintzberg on management : inside our strange world of organizations

Henry Mintzberg revolutionized our understanding of what managers do in The 'Nature of Managerial Work,' his landmark book. Now in this comprehensive new volume, Mintzberg broadens his vision to explore not only the function of management, but also that of the organization itself and its meaning for society. A treasury of the dynamic and iconoclastic ideas that have made him a mentor to an entire younger generation of leading management thinkers, 'Mintzberg on Management' presents the collective wisdom of this influential scholar -- in strategy, structure, power, and politics -- the gestalt of organizational theory. Known as the guru of bottom-up management, Mintzberg broke with convention by actually going inside companies to witness the business of business. Revealing how strategy is really formulated, he shows here that successful strategy is rarely, if ever, born in solitary contemplation
Perceived Adverse Consequences of Quality Threatening Behaviour in Audit Firms

Research in many countries has consistently shown that audit seniors engage in widespread quality threatening behaviours (QTB). Regarding the consequences of these behaviours, only audit partners' perceptions of possible consequences have been examined previously. The objective of this study is to examine audit seniors perceptions of the consequences of QTB for internal and external groups using semi-structured interviews with 25 audit seniors in Ireland. Findings suggest that detection of the behaviours is an important factor in determining the consequences for individual auditors, audit firms and the profession but not for the wider business community. In general, interviewees perceived low risk of detection and showed little consideration of the ethical implications of their actions. No communication was perceived to exist between the firms and audit seniors on prohibition of the behaviours or sanctions against those found guilty of engaging in the behaviours. Although the literature highlights the importance of personnel controls in complex environments such as audit firms, these findings suggest that the effectiveness of personnel controls is undermined by a perception that the likelihood of serious consequences is remote and also by weaknesses in the ethical training of auditors. The use of the term dysfunctional to describe QTB is open to question given the absence of a perceived link between the behaviours and consequences for organisational effectiveness found in this study.
Auditor independence and corporate governance: Ethical dilemmas

Auditors' primary function in society is as purveyors of opinions for reliable and relevant information. Many company failures have highlighted whether auditors have a conflict of interest problem. At the root of auditors' lack of independence, issues are conflicts of interest resulting from the structural features of auditor? client relationship. The throughput model is advanced in order to explain how six dominant ethical positions deal with conflicts of interest problems and corporate governance issues. Finally, a discussion of potential solutions to improve ethical issues is offered for future research.
Privacy and the encryption debate

ConclusionRobert Heinlein, author of Stranger in a Strange Land as well as countless other science fiction stories, once claimed that "The sole thing achieved by any privacy law is to make the bugs smaller. " Heinlein may be correct, but that travesties will happen does not sanction them—and maybe we will invent bugs to root out and foil other bugs.I have argued for individual privacy rights or rights to control sensitive personal information. The explosion of digital technology has made possible severe violations of individual privacy by corporations, news agencies, and the government. If I am correct about all of this, one commonly used "public interest" argument given for limiting privacy rights has been undermined. It is also far from true to claim that the prevalence of strong encryption technology will lead to disaster. While I do not adhere to the view that "rights hold, though the heavens may fall," in this article I have maintained that the security arguments of law enforcement do not come close to meeting the threshold for violating privacy rights. The heavens are far from falling.
The effectiveness of supervisory boards: an exploratory study of challenges in Dutch boardrooms

Triggered by highly publicised corporate scandals, changing societal expectations and the collapse of financial markets, the roles of boards of directors have changed significantly in safeguarding the interest of shareholders and other stakeholders. Yet, relatively little is known about contemporary challenges non–executive directors face and whether their boards are well–equipped for their new tasks. Based on self–assessment reports by supervisory boards, a survey and interviews with supervisory board members, this paper investigates the challenges non–executive directors face in the Netherlands, particularly after a decade of corporate governance reform. Non–executive directors' inadequate role in scrutinising executive directors' performance, information asymmetries and dysfunctional working relationships between executive and non–executive directors are among the greatest challenges indicated by non–executive directors on Dutch supervisory boards. The paper discusses several implications for scholars and practitioners and provides a unique insight in boardroom dynamics.
