Movie clips for teaching business management: Step by step

Abstract The paper proposes a methodology to enhance students’ learning experiences by using movie clips to teach business management concepts. We describe the entire management teaching process step by step, from film selection to evaluation through questionnaires. In this way, this design can be reproduced by instructors for teaching business management courses. Additionally, we carried out and analyzed questionnaires about student satisfaction and business management concepts acquisition with a quantitative multiple regression. The results suggest that watching movies improves academic results and, in particular, the post-viewing debate. Besides, the more current the movie is for the generation of students, the more impact it has on their learning, as they are more likely to pay attention. On the other hand, we cannot neglect the gender issue, as the content of the film has an important influence. Students may be disinterested in a movie with a marked male or female leading role.

Potential of Bacterial Strains Isolated from Coastal Water for Wastewater Treatment and as Aqua-Feed Additives

Bacteria have various and sustained effects on humans in various fields: molecular biology, biomedical science, environmental/food industry, etc. This study was conducted to evaluate the wastewater treatment capacity and feed-additive fish-growth effect of four strains of bacteria: Pseudoalteromonas mariniglutinosa, Psychrobacter celer, Bacillus albus, and Bacillus safensis. In a wastewater degradation experiment, (i) nitrate-N and nitrite-N were removed within 1 h in all of the 4 bacterial strains; (ii) the removal rates of TAN and TN were higher in all of the strains relative to the B. subtilis. In a feed-additive experiment (5% Kg−1), (i) the growth of fish was higher in all of the 4 bacterial strains with the B. subtilis relative to the commercial feed; (ii) there was no significant growth difference for B. albus and B. safensis relative to the B. subtilis, but growth was higher in P. mariniglutinosa and P. celer. The results indicated that the 4 bacterial strains can be effectively utilized for biological wastewater treatment processes and as aqua-feed.
Social Interactions While Grieving Suicide Loss: A Qualitative Review of 58 Studies

The effects of suicide are both widespread and long-lasting in the lives of those closest to the deceased. According to the World Health Organization (WHO), suicide is the third leading cause of death in adolescents. Some research has shown that families who lose someone to suicide are at a higher risk of complicated grief compared to those bereaving from other types of losses. These risks may be emphasized given the socio-cultural context surrounding suicide that may problematize the grieving process. In this review, we analyzed 58 qualitative studies describing the experiences of family who lost someone to suicide. We discuss how negative social interactions due to cultural views towards suicide impacted their grieving process. We provide an integrative interpretation of the experiences of family who lost someone to suicide across the following themes: social withdrawal, family communication approaches, role change, cultural attitudes, the role of professional support, interactions with health care providers, and interactions with religious institutions. We examine these findings using the Assumptive World Theory which proposes that humans seek preservation of their reality by using their perceptions of the past to establish expectations for the future. We find that suicide loss is an experience that challenges people's assumptive worlds; suicide loss can be an unexpected trauma that can have a “shock effect” on the assumptive worlds of the bereaved. The assumptive worlds of relatives grieving suicide loss face unique challenges compared to other forms of bereavement because of ambiguity in social norms surrounding suicide that influence interactions.
Significant metabolic alterations in patients with hepatitis B virus replication observed via serum untargeted metabolomics shed new light on hepatitis B virus infection

Abstract Until now, the metabolic effects of hepatitis B virus (HBV) replication on the progression of hepatic diseases (hepatitis, cirrhosis, and liver cancer) and liver functions have remained unexplored. Thus, a total of 199 hepatic disease patients with active and inactive HBV were enrolled in this study to explore serum metabolic characteristics using untargeted metabolomics. Multiple analyses, including principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), volcano plot and pathway analysis, were used for metabolic data analysis. Additionally, differential metabolites were analysed by commercial databases. A decrease of approximately 0.8-fold in amino acids (L-glutamic acid, D-glutamine and L-tyrosine) and an increase of 2-fold in phosphatidylcholines (PCs) and lysophosphatidylcholines (LPCs) were observed in hepatic disease patients with HBV replication. Moreover, downregulation of arachidonic acid, PC 34:2, sn-glycerol-3-phosphocholine, 1-palmitoylglycerophosphoinositol, and 1-oleoylglycerophosphoinositol by 0.6-fold was also found in the serum of patients with HBV replication. In addition, liver function was significantly different between cirrhosis patients with or without HBV replication (p < .05). In summary, this is the first study to focus on the metabolic changes induced by HBV replication in patients and to compare metabolic alterations in the progression of hepatic disease induced by HBV infection. High levels of amino acid depletion and PC and LPC biosynthesis were primarily observed, which may shed new light on the pathogenesis and treatment of HBV infection.

Corporate environmental performance expectations in the 1990s: More than just compliance

What do General Motors and Ben and Jerry's Homemade Ice Cream have in common? Both companies have endorsed the CERES principles, a model corporate code of environmental conduct developed by the Coalition for Environmentally Responsible Economies (CERES). This model code generally goes well beyond what is now typically required of industry to maintain compliance with already stringent requirements established by regulatory agencies. And the CERES principles are not the only game in town. Many other environmental initiatives have surfaced both in the United States and abroad over the past few years. This article discusses six sets of current initiatives and provides managers with a vital tool for discussing these initiatives with top management and others throughout their organizations.
γ-Tocotrienol Protects against Mitochondrial Dysfunction, Energy Deficits, Morphological Damage, and Decreases in Renal Functions after Renal Ischemia

Ischemia-induced mitochondrial dysfunction and ATP depletion in the kidney result in disruption of primary functions and acute injury of the kidney. This study tested whether γ-tocotrienol (GTT), a member of the vitamin E family, protects mitochondrial function, reduces ATP deficits, and improves renal functions and survival after ischemia/reperfusion injury. Vehicle or GTT (200 mg/kg) were administered to mice 12 h before bilateral kidney ischemia, and endpoints were assessed at different timepoints of reperfusion. GTT treatment reduced decreases in state 3 respiration and accelerated recovery of this function after ischemia. GTT prevented decreases in activities of complexes I and III of the respiratory chain, and blocked ischemia-induced decreases in F0F1-ATPase activity and ATP content in renal cortical tissue. GTT improved renal morphology at 72 h after ischemia, reduced numbers of necrotic proximal tubular and inflammatory cells, and enhanced tubular regeneration. GTT treatment ameliorated increases in plasma creatinine levels and accelerated recovery of creatinine levels after ischemia. Lastly, 89% of mice receiving GTT and 70% of those receiving vehicle survived ischemia. Conclusions: Our data show novel observations that GTT administration improves mitochondrial respiration, prevents ATP deficits, promotes tubular regeneration, ameliorates decreases in renal functions, and increases survival after acute kidney injury in mice.
A Low‐Profile Circularly Polarized Short Backfire Antenna with High Impedance Surface

In this article, high impedance surface (HIS) structures are used as a primary reflector of a short backfire antenna to reduce its profile. Crossed dipoles fed by a power divider with 90° phase shift are adopted as an exciter to realize circular polarization. It is demonstrated that the antenna profile can be reduced from 0.6 to 0.3 λ0 by using the HIS structures as a primary reflector. It also achieves a 3‐dB axial ratio bandwidth of more than 25% with a standing‐wave ratio below 2, and the peak broadside gain is around 13.47 dBi with a 3‐dB gain bandwidth of 22.5%. The simulated and experimental results are presented and discussed in the end of this article. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1779–1784, 2013
Design of an inchworm actuator based on a ferromagnetic shape memory alloy composite

A new inchworm actuator has been designed and fabricated based on a ferromagnetic shape memory alloy (FSMA) composite and the hybrid mechanism. The FSMA composite consists of a ferromagnetic material (soft magnet) and a superelastic grade shape memory alloy. The hybrid mechanism is found to provide relatively large force and stroke with fast response on the FSMA composite because it can be driven by a compact electromagnetic driver with high applied magnetic field gradient, providing a large stress capability and reasonably large strain. The inchworm actuator exhibits moderate output force and very large displacement, achieved by accumulating many small strokes based on the inchworm mechanism. The prototype inchworm actuator successfully produces 30 N force and 65 mm s−1 stroke velocity.
Micropropagation of Solanum lycopersicum L. using chemical free formulated organic plant growth media

Micropropagation is currently the most commercially effective plant biotechnology that helps in the rapid generation of a large number of clonal plants of many plant species in a short period. Effective protocol was developed for in vitro micropropagation of Solanum lycopersicum (tomato) using chemical-free organic vermicompost (VC) extract medium. This experiment aims to expose the advancement in plant tissue culture technique by using synthetic Murashige and Skoog medium (MS) medium and a chemical-free organic VC (30%) extract along with 4% coelomic fluid (obtained from the earthworms Eudrilus eugeniae) as a growth medium for in vitro studies. The response of roots, leaves, shoots, and nodes in both synthetic (MS) medium and chemical-free organic VC extract medium was compared statistically using Student’s t-test. Statistically significant differences for the number of roots (P =0.011), leaves (P=0.012), and nodes (P=0.001) between the two media were reported. Both media showed the same shoot induction where no significant differences were reported with a P value of 1.000 for shoots. The protocol has led to a 100% plant survival rate on chemical-free organic vermicompost extract media. The results have also shown a significant difference in growth rate between two different media. Vermicompost and coelomic fluid used in media have antimicrobial activities which led to minimal contamination level and this consequently minimized timely subculturing. Through our studies, we found that chemical-free organic vermicompost extract media proved to be more economical and a better prospective than MS media for in vitro propagation of tomato.
Trend and variability of hourly intensity of rainfall over eastern and northern part of Uttar Pradesh during 1969-2014

It is now widely accepted question that average value of the world temperature has gone up because of climatologically significant emission of greenhouse gases by means of anthropogenic sources. Global warming may be witnessed by changes in the frequency of occurrence of the extreme weather events such as severe floods, storms and drought. The topic of climate change is being discussed on international platforms. With this reference reports of Intergovernmental panel on climate change (IPCC) are important. In this era of climate change and global warming, we set the objective of this study to find out the trend and intensity of rainfall in the selected four stations, viz., Barielly, Lucknow, Allahabad and Bapatpur (Varanasi Airport) of Uttar Pradesh (UP), India based on hourly rainfall data. These stations are selected on better data availability and to represent eastern and northern part of UP. Firstly hourly rainfall data of all four stations ranging from 1969 to 2014 is examined. The percentile of hourly data is calculated to define various intensities of hourly rainfall of the stations. Based on different percentiles groups, intensity of the rainfall is classified into very light spell, light spell, moderate spell, intense spell, very intense spell, extremely intense spell , exceptionally intense spell. For each percentile group, yearly, monthly, JJAS (monsoon) frequency distribution is prepared. Frequency distribution trend is analyzed by means of t-test, p-value, slope and R square. Statistical significance of the trend is done by t-test. It is found that the rainfall of different intensities in yearly, monthly, JJAS (monsoon) for all the four stations is not statistically significant. From this it may be infer that even in the era of climate change, the trend and intensity of hourly rainfall in the eastern and northern parts of UP is not changed.
Service Chain Caching and Workload Scheduling in Mobile Edge Computing

The computing and storage resources of an edge node in a mobile edge computing (MEC) system are limited. One edge computing node cannot cache all the services supported by the entire MEC system. A service chain caching and scheduling strategy should be designed to improve the service processing capacities of the edge computing nodes under high computing load conditions. This article combines the open Markov queuing network for the first time to model the process of edge node analysis and processing of computationally intensive tasks as a mixed integer nonlinear programming problem. Moreover, a mathematical model for the service chains is established. We analyze the average service response time during task execution to optimize the performance of service chain caching and scheduling. Experiments show that the outer approximation (OA) algorithm obtains better results than MindtPy and Multistart. The average response time obtained by the OA algorithm is 2.2% and 6.9% lower than those obtained by the MindtPy and Multistart algorithms, respectively. The OA algorithm using this mathematical model can effectively reduce the average service response time and improve the resource utilization of the edge server.
Guided-Wave Superconducting Quantum Optoelectronic Devices

This thesis investigates a novel optoelectronic platform based on the integration of superconductive structures, such as thin films and micro-constrictions, with optical waveguides for ultra-fast and ultra-sensitive devices with applications including high-speed optical communications, quantum optical information processing, and terahertz (THz) devices and systems. The kinetic-inductive photoresponse of superconducting thin films will be studied as the basic optoelectronic process underlying the operation of these novel devices. Analytical formulation for the non-bolometric response is presented, and experimental photodetection in YBCO meander-line structures will be demonstrated. A set of superconducting coplanar waveguides (CPW) are designed and characterized, which support the operation of the devices at microwave frequencies. Microwave-photonic devices comprising a microwave transmission line and a light-sensitive element, such as a meander-line structure, are designed and measured for implementation of optically tunable microwave components. In order to support low-loss and low-dispersion propagation of millimeter-wave and THz signals in ultra-fast and wideband kinetic-inductive devices, surface-wave transmission lines are proposed, incorporating long-wavelength Surface Plasmon Polariton (SPP) modes in planar metal-dielectric waveguides. The theory of superconducting optical waveguides, including analytical formulation and numerical methods, is developed in detail. The implementation of superconducting optical waveguides is discussed thoroughly, employing conventional dielectric-waveguide techniques as well as optical SPP modes. Superconductive traveling-wave photodetectors (STWPDs) are introduced as a viable means for ultra-fast and ultra-sensitive photodetection and photomixing. A modified transiii mission line formalism is developed to model STWPDs, where light is guided through an optical waveguide and photodetection is distributed along a transmission line. As an appendix, a systematic approach is developed for the analysis of carrier transport through superconducting heterostructures and micro-constrictions within the Bogoliubovde Gennes (BdG) framework. The method is applied to study the role of Andreev reflection and Josephson-like phenomena in the current-voltage characteristics of inhomogeneous superconducting structures. I-V characteristics are experimentally demonstrated in YBCO micro-constrictions with potential applications in millimeter-wave and THz devices.
Projected Kaczmarz successive interference cancellation detection

In this article, the recently developed Kaczmarz successive interference cancellation (KSIC) detector is generalized to the nonlinear case; specifically, a projected SIC detection scheme is developed using the projected Kaczmarz iterative method. This novel detector enjoys improved performance with minimal additional computational complexity. The new detector is first presented and then its convergence analysis is detailed. After that, the computational complexity analysis of this detector is conducted and compared to that of the KSIC detector. Finally, extensive numerical simulations are conducted in different scenarios. Simulation results show that the proposed projected Kaczmarz SIC detector can achieve lower BER and can support more users in the system compared to the KSIC detector.
STRENGTHENING OF A STEEL BRIDGE GIRDER USING CFRP PLATES

For bridge owners faced with a rising number of structurally deficient steel bridges, the rehabilitation of steel girders using advanced composite materials offers an attractive solution for short-term retrofit or long-term rehabilitation. Several laboratory studies conducted at the University of Delaware have shown that carbon fiber-reinforced polymer (CFRP) plates can be used to effectively strengthen steel bridge girders. Initial studies focused on several issues including the effect on global stiffness and strength, bond force transfer and development, and environmental and fatigue durability of the CFRP/steel bond. Once the feasibility of the strengthening procedure had been thoroughly examined, strengthening of an existing steel bridge girder was performed. This paper reviews the research conducted to date, and presents details of a demonstration of this technology performed on a bridge located on Interstate 95 in Newark, Del.
