Towards Supporting and Documenting Algorithmic Fairness in the Data Science Workflow

Recent pushes to replace human decision-makers with machine learning models have surfaced concerns about algorithmic fairness. These concerns have led to a quickly growing literature on defining fairness and making models transparent. In practice, the data scientist building the model necessarily must make difficult tradeoffs choosing between imperfect models, balancing different definitions of fairness with accuracy and other considerations. Because these choices have ethical dimensions, there is a need to better support these choices and both document and justify them for the public. We outline a research agenda towards better visualizing difficult fairness-related tradeoffs between competing models, empirically quantifying societal norms about such tradeoffs, and documenting these decisions. We outline how the best practices that result could enable a consumer protection framework for accountable fairness.
Effect of impeller submergence on power dissipation and solids suspension in mixing systems equipped with pitch-blade turbines

EFFECT OF IMPELLER SUBMERGENCE ON POWER DISSIPATION AND SOLIDS SUSPENSION IN MIXING SYSTEMS EQUIPPED WITH PITCH-BLADE TURBINES By Yufeng Song Mixing and dispersion of solids in a liquid is a process frequently encountered in the pharmaceutical industry and often conducted in cylindrical baffled tanks stirred by mechanical impellers. In operations where the liquid level is decreased (as often which emptying the tank) the process must be stopped when the solids are no longer suspended. In this work, the minimum agitation to suspend solids (Njs) when the liquid level was lowered, and the impeller submergence Sb changed as a result were determined for the case of a six-blade, pitch-blade turbine (6-PBT) impeller. The power consumed by the impeller was also measured. It was found that when a critical impeller submerge level was reached it was impossible to suspend the solids and the impeller power decreased significantly, although the impeller was still full submerged. The results are important to ensure that mixing systems are operated properly.

Link Prediction based on Deep Latent Feature Model by Fusion of Network Hierarchy Information

Link prediction aims at predicting latent edges according to the existing network structure information and it has become one of the hot topics in complex networks. Latent feature model that has been used in link prediction directly projects the original network into the latent space. However, traditional latent feature model cannot fully characterize the deep structure information of complex networks. As a result, the prediction ability of the traditional method in sparse networks is limited. Aiming at the above problems, we propose a novel link prediction model based on deep latent feature model by Deep Non-negative Matrix Factorization (DNMF). DNMF method can obtain more comprehensive network structure information through multi-layer factorization. Experiments on ten typical real networks show that the proposed method has performances superior to the state-of-the-art link prediction methods.
The study of ff electronic transition spectra of ternary complexes of Sm ( III ) with some crown ethers and some amino acids

The ternary complexes[Sm-CW-AA] have been prepared by interacting the Sm (III) metal ion [M] with the crown ethers [L1]:18–Crown–6, benzo-18-Crown-6 & dibenzo-18-Crown-6 & the amino acids [L2]: glycine, -alanine & L-arginine, respectively, in various metalligands stoichiometries [M:L1:L2] ratio. The electronic spectra of these complexes have been recorded in visible region, in solution. The intensity of the nine selected bands of the f-f electronic transition spectra have been analyzed & characterized. The spectra have been quantified in terms of intensity parameters: Oscillator strength (Posc) & Judd-Ofelt (T2, T4 & T6) and the bonding parameters: Nephelauxetic ratio (β) & co-valency ( b 1/2 ). All these parameters have been computed using partial and multiple regression methods given by Wong and others. The variation in these parameters for the complexes with respect to the free ion shows the complexation reaction, change in symmetry around metal ion, structure of the complexes/ligand, nature of metal-ligand bond etc. Typically, the T2 parameter is associated with short-range coordination effects. Nevertheless, the other two parameters, T4 & T6, depend on long range effects. Also these are crucial for evaluating their performance as the laser or photoluminescent material. The metal-ligands stoichiometries [Sm: CW: AA] ratio of these complexes have also been determined using Mole Ratio method. This was found to be [1:3:2], in general.

The Effect of Brand Equity and Perceived Value on Customer Revisit Intention: A Study in Quick-Service Restaurants in Vietnam

The purpose of this study is to examine how brand equity, from a customer point of view, influences quick-service restaurant revisit intention. The authors propose a conceptual framework in which three dimensions of brand equity including brand associations combined with brand awareness, perceived quality, brand loyalty and perceived value are related to revisit intention. Data from 570 customers who had visited four quick-service restaurants in Ho Chi Minh City were used for the structural equation modelling (SEM) analysis. The results show that strong brand equity is significantly correlated with revisit intention. Additionally, the effect of brand equity on revisit intention was mediated by perceived value, among others. Overall, this study emphasizes the importance of perceived value in lodging in the customer’s mind. Finally, managerial implications are presented based on the study results.
Does Corporate Charitable Giving Help Sustain Corporate Performance in China?

We examined whether corporate charitable giving (CCG) in China benefits corporate performance (CP) in terms of sales growth (SG), return on asset (ROA), return on equity (ROE), and Tobin’s Q (TQ), and revealed several findings. First, testing shows variation in the impact of CCG on CP. Whereas the ratio of corporate charitable giving (RCCG) to total sales revenue does not significantly enhance SG, ROA, and ROE, it is positively related to TQ. Second, the positive relationship between RCCG and TQ originates from non-state-owned firms (NSOFs) rather than state-owned firms (SOFs). Third, Chinese firms may use CCG as traditional philanthropy to enhance long-term performance instead of strategically using it to generate short-term performance. Lastly, an inverted U-shaped relationship exists between RCCG and TQ, especially for NSOFs.
A comparative study of cadmium uptake by cells of gram-positive and gram-negative bacteria

Title of thesis: A Comparative Study of Cadmium Uptake By Cells of Gram-Positive and Gram -Negative Bacteria. Shubhangi Bhende: Master of Science in Environmental Science, 1990 Thesis directed by: Sam S. Sofer, professor Sponsored Chair in Biotechnology Cadmium uptake by cells of Gram-positive and Gramnegative bacteria was studied. Gram-positive and Gramnegative bacterial cells were separated from activated sludge collected from the Parsippany Troy Hills Water Pollution Control Plant (NJ) by isolating them on agar plates. These were grown separately and used for uptake experiments. Gram-positive bacterial cells showed 17% more uptake of cadmium as compared to Gram-negative cells at 30°C and pH 6.6. More than 95% of the total cadmium removal from the solution was observed during first 5 min. of cell-metal contact time. In case of Gram-positive bacteria cadmium uptake decreased by 5-10% after cells were inhibited by contacting with 1M sodium azide for 45 min. In the case of Gram-negative bacteria, uptake decreased by 4-5% under same conditions. Cadmium uptake increased by 13% in Gram-positive bacteria after addition of nutrients, suggesting some metabolic uptake of cadmium. Although cadmium uptake decreased by 4-5% after inhibition of cells with sodium azide, there was no significant increase in cadmium uptake by Gram-negative bacteria after nutrient addition. A COMPARATIVE STUDY OF CADMIUM UPTAKE BY CELLS OF GRAMPOSITIVE AND GRAM-NEGATIVE BACTERIA. by 1,1' 'I -1 ShubhangiBhende Thesis submitted to the Faculty of the Graduate school of the New Jersey Institute of Technology in partial fulfillment of the requirements for the degree of Master of Science in Environmental Science. 1990
Inhibition of dipeptidyl peptidase IV by fexofenadine: Virtual screening study

Dipeptidyl peptidase IV (DPP IV) is relatively new anti-diabetic target. DPP IV inhibitors lower fasting and postprandial glucose concentrations by preventing the degradation of the natural hypoglycemic incretin hormones: glucose-dependent insulinotropic peptide and glucagon-like peptide-1. In this work, the high throughput docking software FRED was used as a virtual screening tool against in house built drug database to discover new DPP IV inhibitors. One of the highest ranking hits, the antihistamine drug fexofenadine, was found to inhibit recombinant human DPP IV in vitro with IC50 = 4.6 (±1.0) μM. The anti-diabetic effect of fexofenadine was validated in vivo by oral glucose tolerance test. These results could be helpful in the development of novel DPP IV inhibitors based on fexofenadine scaffold for the treatment of type 2 diabetes.
Analysis of the Influence of Displacement on Finger Photoplethysmography for Wearable Health Monitoring Sensors

The ring sensor is a miniaturized, telemetric, monitoring device worn by a patient as a finger ring. The ring encapsulates photoplethysmographic, pulse oximetry combined with wireless communication and miniaturization technologies. This report describes the development of an opto-physiological model of a finger in conjunction with a ring-type photoplethysmography device (the Ring Sensor). This model is a combination of an optical model, a mechanical model, a skin capillary model and the arterial wall dynamics. It describes the photoplethysmographic effects due to the relative displacement and rotation of a finger to a ring-type opto-electric device that monitors the arterial pulsation noninvasively and continuously. Numerical simulations and experiments were conducted to verify and evaluate this model. Extensive finite element analysis was conducted, and its results were compared with the model. Based on this analysis, the advantage of isolating ring sensor was verified by FEM.

Driving and Testing Crystal-free Radios for a Basic End-to-End Transmission

Wireless sensor networks consist of a collection of small, inexpensive, independent nodes, capable of sensing various properties of their environment, and connected together in a wireless network. In order to make them autonomous, non-invasive and cheap, a monolithic integration is envisioned. The renunciation of off-chip components strongly affects the radio design of such a node which usually relies on an external quartz crystal as frequency reference. Using an on-chip frequency reference such as a ring oscillator leads to a high phase noise profile. Little is known about the impact of high phase noise on a continuous radio transmission and its understanding is therefore crucial to be able to design a monolithic sensor node. In the following work a complete macro-scale test system consisting of a digital transceiver integrated on a FPGA controlled by software, a customdesigned MSK modulation PCB with a PLL, and an RF radio circuit using minicurcuits components is presented. It follows the IEEE 802.15. 4 standard and emulates a radio communication at 2.4 GHz between two monolithic sensor nodes relying on frequency references with a high phase noise profile of -80 dBc at 1 MHz frequency offset. Based on the test system a successful transmission with a data rate of 100 kbps has been demonstrated, remotely controlling small MEMS structures. The receiver’s demodulation PLL was able to track a 500kHz frequency drift of the radio signal and could keep up the transmission for multiple hours. No significant signal power degenerations as side-effect of high phase noise exposure were observed. This proofs the feasibility of a radio transmission with a high phase noise profile frequency reference and thus the design of monolithic sensor nodes. Furthermore, the demodulation structure based on a PLL revealed the ability to track frequency instabilities. The made test system lays the foundation for further testing and measuring of additional parameters of monolithic sensor nodes.
The increasing importance of sustainability for building ownership

Purpose — This study seeks to investigate the degree to which energy efficiency is incorporated into office building refurbishment and capital expenditure with the emphasis placed on a cost‐benefit analysis from the owner’s perspective. Design/methodology/approach – In order to develop a research framework, a thorough literature review was conducted of three disciplines being construction technology, building refurbishment and property management. The study identifies differences between varying levels of capital expenditure to ensure an existing building is more energy efficient, with the emphasis placed on the cost of implementation and the potential for tenants to acknowledge the increased energy efficiency via higher rents. Findings – Office buildings have been identified as a contributor to global warming during the construction phase, however during the building lifecycle there is a greater contribution to CO2 omissions. Whilst various building designs and construction techniques have evolved to improve energy efficiency, the focus has largely been placed on new buildings where it is easier to incorporate change and innovative approaches. However, the proportion of new buildings constructed each year is relatively small in comparison to existing building stock, which requires regular capital expenditure to maintain and attract new tenants within a competitive marketplace. Practical implications – The increasing importance of energy efficiency affects the office market in a variety of different ways. Originality/value – This paper identifies important links between the environment and the built environment, and the implications for office building owners.
JOURNAL OF RURAL COOPERATION

Research has shown that the structure and strategies adopted by cooperatives can be affected by market characteristics (e.g. deregulated versus regulated markets). This study examined the effects of these market characteristics on non-economic drivers that influence farmers’ willingness to participate in cooperation. The example studied was the incentives of ex-sugar beet farmers in the UK to informally cooperate with their neighbors, and whether these incentives changed in response to the EU Sugar Regime Reform of 2006. The method used was regression analysis based on a theoretical behavioral framework. The results revealed that most of the non-economic drivers influencing farmers’ incentives to cooperate before and after the reform were not the same. This finding has implications in relation to the
Automated Veri cation of Mobile Code

In this thesis, we introduce a new technique to automate the veri cation of mobile code. Using data ow analysis techniques, the veri er can check whether data passed between trusted software components is illegally modi ed by untrusted mobile code. We show that this analysis is powerful enough to make signi cant guarantees about whether the program will access system resources safely. Furthermore, by rendering the veri cation transparent to the user, the security system is not vulnerable to human error, or dependent on the user's technical abilities. Other veri cation techniques do not share these advantages. We describe what requirements enable this analysis, explore its limitations, and present prototype software that implements the idea.
X ON THE DESCRIPTION OF TRANSVERSE WAVE PROPAGATION ALONG THIN MAGNETIC FLUX TUBES

Two approaches are used for description of linear transverse (kink) modes excited in a vertical thin magnetic flux tube. First one is based on the elastic thread model (Spruit, 1981). The second one follows from the the Taylor and Laurent series expansions of wave variables with respect to the tube radius inside and outside of the magnetic flux tube (Lopin and Nagorny, 2013). It has been shown that the main reason of the discrepancy of these approaches is related to the phenomenological equation of plasma motion used in the former case. This suggests that results obtained on the basis of this equation should be revised.
Path to an Integrated Modelling between IFC and CityGML for Neighborhood Scale Modelling

Planning of the built environment requires two-levels of planning process, city/neighborhood-scale and building-scale levels. At the city/neighborhood-scale, Geographic Information System (GIS) is commonly used with CityGML as its open-source 3D format. Meanwhile, for building-scale, Building Information Modelling (BIM) is used, and Industry Foundation Classes (IFC) format is its open-source file format. Both technologies work on different data formats and data exchanges. The research is focusing on ways of exchanging information and bringing together CityGML and IFC. With local context input, the methodology could be considered as a framework to parametrically manage the information related to energy, environment, security, etc. In this project, two use cases were developed, such as visualization for a web application. Autodesk Revit and Graphisoft Archicad were used in developing the building models as a prototype for the transformation testing. The transformation system was developed using Feature Manipulation Engine (FME), by Safe Software. FME allowed us to restructure the data model (IFC) and transformed it to the destination data format (CityGML). The test results showed that from detailed BIM models, CityGML format, as well as a Sketchup file, could be generated. These models can be imported to web visualization applications for urban energy modelling.
Sports Metaphors in American Political Discourse

In cognitive linguistics, conceptual metaphor refers to the understanding of an idea in terms of another familiar object. As conceptual metaphors are great persuasive means due to their ability to make unfamiliar things familiar, we have analyzed transcripts of recent political speeches with a special reference to presidential campaign speeches (2016-2019). It should be noted that the usage of conceptual metaphors is strictly linked to cultural patterns, i.e. Asian people tend to use conceptual metaphors of eating or family, while Western politicians tend to rely on sport, driving or war metaphors. The thing is that they consciously, subconsciously or even unconsciously view their lives as a race, a game or a battle. Our analysis is based on Western presidential campaign speeches. As an outcome of our analysis we wanted to reveal and elucidate that particular link between culture and cognitive linguistics.
Parallel execution of quantum gates in a long linear ion chain via Rydberg mode shaping

We present a mechanism that permits the parallel execution of multiple quantum gate operations within a single long linear ion chain. Our approach is based on large coherent forces that occur when ions are electronically excited to long-lived Rydberg states. The presence of Rydberg ions drastically affects the vibrational mode structure of the ion crystal giving rise to modes that are spatially localized on isolated sub-crystals which can be individually and independently manipulated. We theoretically discuss this Rydberg mode shaping in an experimentally realistic setup and illustrate its power by analyzing the fidelity of two conditional phase flip gates executed in parallel. Our scheme highlights a possible route towards large-scale quantum computing via vibrational mode shaping which is controlled on the single ion level.
