This research explores the key factors that contribute to the success of Black students in a predominantly White institution (PWI). Two measures of success are examined: cumulative grade point average (GPA) and graduation status.

Using student-level data from a southeastern university, this research estimates education production functions using ordinary least squares regression.

While the negative effect of being Black is significant for both cumulative GPA and graduation status, the effect becomes overshadowed when peer effects are added. The authors also found the critical effect of institutional support on student success.

The student-level data are restricted to a single institution over a relatively short period of time, which limits the authors' ability to analyze institution-level factors.

This research provides a broad view of many significant factors for student success with particular highlights on the importance of encouraging Black students to utilize institutional support.

This study is an extension of the education production function model in the field of student success. The study identified peer effects and institutional support as more powerful determinants of student success than race.

The purpose of this paper is to explore user-centered design possibilities at the intersection of gamification and persuasive technology to foster energy saving behavior.

We performed a large-scale empirical study of 480 participants and analyzed how different HEXAD gamification user types perceive selected persuasive strategies embedded in an energy saving prototype. Furthermore, we investigated the role of existing energy saving behaviors (pro-environmental behavior scale–e.g. regularly turning the lights off) and their effect on the perceived persuasiveness of the proposed persuasive strategies, which may has an impact on the overall design process. Furthermore, we applied partial least squares path modeling and conducted a one-way and repeated measure ANOVA.

Results show that user types play an important role in the design of persuasive systems for energy saving. For instance, people with a high tendency toward the Socializer user type were motivated by almost all of the employed persuasive strategies, whereas Philanthropists and Players only to a limited number of strategies. Furthermore, our study reveals that existing behaviors like the individual level of energy conservation influences the perceived persuasiveness of certain strategies and therefore should be considered in the design of such applications.

Using storyboards to obtain feedback about the perceived persuasiveness of employed strategies has limitations compared to the actual use of a functional prototype. However, to offset that limitation the mock-ups used in the storyboard reflected the actual designs for a real-world prototype.

This is the first study that explores how HEXAD gamification user types can be used to inform the design of persuasive applications for energy saving (RQ1). Furthermore, and in particular, this study draws on the challenges when using user types within gamified persuasive systems by highlighting the impact and the importance of considering existing energy saving behaviors (RQ2), which has not been addressed so far.

Powder coating in the car industry. “The future for powder coatings in the car industry is bright”, Chrysler Corporation's Ernie McLaughlin said in the keynote address at the recent Powder Coating '94 in Cincinnati.

Despite many troublesome aspects in its use, the risk-adjusted discount rate has survived and continues to be extensively used by practitioners. While the appropriate discount rate for projects as risky as the current business operations of the firm can be estimated relatively easily as the firm’s cost of capital, no clear guideline is available for projects with a higher risk profile. The purpose of this paper is to evaluate an appropriate risk addendum for such risky projects.

Extending the framework developed by Davies et al. (2012), the perceived risk in a project is captured by focussing on a downside case scenario and estimating its probability and severity. An expression is then developed for the risk addendum (as an addendum to the firm’s cost of capital) that can be used to find the value of a risky project.

The risk addendum is found to depend only on the product of the probability (p) and the severity (d) of the downside case scenario and not on either of them individually It was also found that the risk addendum rises fast for projects with shorter lives and so is the highest for risky projects with short lives.

Managers can use the expression derived to evaluate an appropriate risk addendum for risky projects.

The paper suggests a simple framework to quantify the risk involved in a project and to evaluate an appropriate risk addendum.

Soft robotics is currently a rapidly growing new field of robotics whereby the robots are fundamentally soft and elastically deformable. Fabrication of soft robots is currently challenging and highly time- and labor-intensive. Recent advancements in three-dimensional (3D) printing of soft materials and multi-materials have become the key to enable direct manufacturing of soft robots with sophisticated designs and functions. Hence, this paper aims to review the current 3D printing processes and materials for soft robotics applications, as well as the potentials of 3D printing technologies on 3D printed soft robotics.

The paper reviews the polymer 3D printing techniques and materials that have been used for the development of soft robotics. Current challenges to adopting 3D printing for soft robotics are also discussed. Next, the potentials of 3D printing technologies and the future outlooks of 3D printed soft robotics are presented.

This paper reviews five different 3D printing techniques and commonly used materials. The advantages and disadvantages of each technique for the soft robotic application are evaluated. The typical designs and geometries used by each technique are also summarized. There is an increasing trend of printing shape memory polymers, as well as multiple materials simultaneously using direct ink writing and material jetting techniques to produce robotics with varying stiffness values that range from intrinsically soft and highly compliant to rigid polymers. Although the recent work is done is still limited to experimentation and prototyping of 3D printed soft robotics, additive manufacturing could ultimately be used for the end-use and production of soft robotics.

The paper provides the current trend of how 3D printing techniques and materials are used particularly in the soft robotics application. The potentials of 3D printing technology on the soft robotic applications and the future outlooks of 3D printed soft robotics are also presented.

The paper introduces and illustrates the use of numerical models for the simulation of electromagnetic and thermal processes in an absorbing ceramic layer (susceptor) of a new millimeter-wave (MMW) heat exchanger. The purpose of this study is to better understand interaction between the MMW field and the susceptor, choose the composition of the ceramic material and help design the physical prototype of the device.

A simplified version of the heat exchanger comprises a rectangular block of an aluminum nitride (AlN) doped with molybdenum (Mo) that is backed by a thin metal plate and irradiated by a plane MMW. The coupled electromagnetic-thermal problem is solved by the finite-difference time-domain (FDTD) technique implemented in QuickWave. The FDTD model is verified by solving the related electromagnetic problem by the finite element simulator COMSOL Multiphysics. The computation of dissipated power and temperature is based on experimental data on temperature-dependent dielectric constant, loss factor, specific heat and thermal conductivity of the AlN:Mo composite. The non-uniformity of patterns of dissipated power and temperature is quantified via standard-deviation-based metrics.

It is shown that with the power density of the plane wave on the block’s front face of 1.0 W/mm², at 95 GHz, 10 × 10 × 10-mm blocks with Mo = 0.25 – 4% can be heated up to 1,000 °C for 60-100 s depending on Mo content. The uniformity of the temperature field is exceptionally high – in the course of the heating, temperature is evenly distributed through the entire volume and, in particular, on the back surface of the block. The composite producing the highest level of total dissipated power is found to have Mo concentration of approximately 3%.

In the electromagnetic model, the heating of the AlN:Mo samples is characterized by the volumetric patterns of density of dissipated power for the dielectric constant and the loss factor corresponding to different temperatures of the process. The coupled model is run as an iterative procedure in which electromagnetic and thermal material parameters are upgraded in every cell after each heating time step; the process is then represented by a series of thermal patterns showing time evolution of the temperature field.

Determination of practical dimensions of the MMW heat exchanger and identification of material composition of the susceptor that make operations of the device energy efficient in the required temperature regime require and expensive experimentation. Measurement of heat distribution on the ceramic-metal interface is a practically challenging task. The reported model is meant to be a tool assisting in development of the concept and supporting system design of the new MMW heat exchanger.

While exploitation of a finite element model (e.g. in COMSOL Multiphysics environment) of the scenario in question would require excessive computational resources, the reported FDTD model shows operational capabilities of solving the coupled problem in the temperature range from 20°C to 1,000°C within a few hours on a Windows 10 workstation. The model is open for further development to serve in the ongoing support of the system design aiming to ease the related experimental studies.

The role of Teacher Innovative Behavior (TIB), in responding to systemic problems in educational systems and promoting “intrapreneurial” behavior has been recognized in recent times. A robust instrument that can help administrators and teacher educators gauge the levels of TIB among their teachers will facilitate the promotion of innovative behavior.

This study tested a multidimensional innovative behavior inventory (IBI), innovation support inventory (ISI) and innovation output (IO) in a developing nation (India) context with public school teachers (n = 34,754), for reliability, validity, measurement invariance and structural invariance across caste, gender and subject groups.

The IBI, ISI and IO showed good reliability and validity along with full measurement invariance at configural, metric and scalar levels. With respect to the structural parameters, the inventories exhibited invariance of factor variance and covariance, but not of factor means.

Teacher innovative behavior (TIB) is seen by developing country education administrators as a tool to address difficult problems. With better measurement, it will be possible to identify teachers who need training in creativity and entrepreneurial behavior, teachers who might have developed innovative practices that could be used for teacher development, and ways of promoting competition among teachers.

The study validates inventories, which were earlier tested in non-educational domains, for use with public school teachers of a developing country across gender, caste and subject groups.

Organizations must focus on increasingly complex and customized products and production processes integrated into technological and digital evolution. Thus, shop floor operators have a more significant number of complex tasks with responsibility for their quality control, looking for high productivity levels. However, there are human limitations to deal with the increased amount of information/data resulting from the integration of new technologies. As such, the main research objective is to answer the following research question “How can the combination of recent smart technologies with the human factor contribute to employees' involvement at the shop floor level and thus improve quality control?”

This study follows a qualitative research approach by developing a singular case study in CPMG PSA Group – Peugeot Citroën, where two innovative information technology (IT) projects were implemented following the continuous improvement methodology PDCA cycle (Deming, 1986).

This work contributed to highlighting the human-centered approach in the discussion of Quality 4.0 development. The main theoretical contribution of this research is the identification of a set of key elements that should be present in the integration of the information technologies in quality control, namely: Prioritizing the quality problems supported by the fundamentals knowledge and tools of traditional quality management (QM); building multidisciplinary teams at different organization levels; following approaches that promote continuous improvement; developing the human-centered and user-friendly perspective; implementing solutions as directly as possible in the workstation; finally, enabling an effective communication and motivation strategies.

The research addresses a singular case study and solely explores the vertical integration process of Quality 4.0.

The projects presented may inspire other organizations to integrate information technologies solutions in quality control, following the implementation process and the essential elements described in these examples. Thus, this research stresses that one should customize these projects with the involvement of shop floor operators in a human-centered and user-friendly perspective, both at the preliminary and succeeding stages.

This research presents two original and customized projects, bridging the technological perspective with the human factor in the digital transformation era, supporting the worker, not replacing it.
