Discrimination law has evolved from litigating or prosecuting overt, individual cases of egregious behavior solely by means of anecdotal evidence and eyewitness testimony. Statistical evidence came to bear the imprimatur of the United States Supreme Court in the Seventies as a probative means of discerning guilt or liability, and has been used to shore up patterns of prejudice at a systemic level since. Courtrooms of the Twenty-First Century have struggled to define discrimination through a quantitative lens, nonetheless relying on qualitative evidence to assist the factfinder in rendering a verdict. Some definitions carry more precision and accuracy than others. Consider the inflammatory National Law Journal's indictment of the United States Environmental Protection Agency (‘EPA’) as an example of the latter. In 1992, the National Law Journal ran a Special Investigation of the EPA, claiming that the federal government had fostered a racist imbalance in hazardous site cleanup and its pursuit of polluters. Kudos to the columnists for bringing environmental equity into the spotlight of public debate and for forewarning and encouraging the EPA to conduct its enforcements reflectively, in order to avoid being on the receiving end of a Title VI lawsuit. Nonetheless, the methodology used by the National Law Journal belies a total understanding of the bureaucratic structure that pursued these actions and of the notion of statistical significance. This Article confines itself to Region X's actions between 1995 and 1999, applying linear regression and other statistical tests to determine whether biases, found using the National Law Journal's naive methodology, stand after due consideration of chance. The NLJ approach finds evidence of bias, but the author also conducts more complicated and appropriate analyses, such as those contemplated by the National Guidance. After issuing some provisos, the author dismisses charges of racism or classism. While the National Guidance represents a positive first step in identifying environmental justice communities, those with an above-average proportion of lower-class or non-Caucasian inhabitants, it lacks statistical sophistication and econometric depth. This Article concludes by recommending the use of normalized racial distributions, Gini coefficients, and Social Welfare Functions to the EPA and to other organizations conducting environmental justice analysis.

The main purpose of this paper is to investigate the influence of build orientation on the tensile properties of PolyJet 3D printed parts. Effects on manufacturing time and total cost per part are the secondary objectives.

Solid tensile specimens were prepared as per the American Society for Testing and Materials D638 standards and were manufactured in six different orientations by using the Objet260 Connex 3D printer. VeroWhitePlus RGD835 was used as the build material, with FullCure 705 as the support material. The specimens were tested for their tensile strength and elongation. The side surface and the fracture surface were analyzed using the Field Emission Scanning Electron Microscope-SIGMA HV-Carl Zeiss with Bruker Quantax 200-Z10 EDS detector. Scanning electron microscope images of each surface were obtained at various magnifications.

From the study, it can be concluded that build orientation has an influence on the tensile strength and the manufacturing cost of the parts. The microstructural analysis revealed that the orientation of surface cracks/voids may be the reason for the strength.

From literature survey, it is inferred that this study is sure to be among the first few under this topic. These results will help engineers to decide upon the right build orientations with respect to print head so that parts with better mechanical properties can be manufactured.

This paper aims to investigate the Occupational Safety and Health (OSH) management practices of construction companies in South Korea to ascertain specific components and practices that need improvement for successful OSH performance.

A quantitative research strategy was adopted. A close-ended questionnaire survey covering 45 OSH management practices was sent to 324 contractors; 108 responses were gathered, representing a response rate of 33.3%. Data were analysed using simple descriptive statistics (frequencies and percentages) and Pearson’s chi-square test.

The findings revealed that there is a moderate level of implementation of OSH management practices among construction firms in South Korea. However, there is a significant disparity in terms of implementation between large enterprises on the one hand and small to medium enterprises on the other. Furthermore, a few of the business characteristics (i.e. the size of companies and certification to OHSAS 18001) were closely associated with the extent of the implementation of OSH management practices.

This research uncovers the OSH management practices that are poorly implemented and lays the foundation for appropriate measures to improve OSH in South Korean construction companies. It suggests an effective strategy for communicating health and safety issues to workers, training safety managers, reviewing risk assessments, reviewing the health and safety plan, incentivising workers by rewarding good behaviour and having a penal mechanism for employees not adhering to the rules.

The study provides insights into an under-investigated South Korean construction industry topic. It offers additional insight into state-of-the-art health and safety management practices in the construction industry in South Korea. Furthermore, it establishes which components of OSH management practice require improvement in the Korean context. This is also one of the few studies in OSH which establishes the association between the construction business characteristics and OSH management in the South Korean construction domain.

This study aims to use porous concrete and mineral adsorbents (additives) for reducing the quantity and improving the quality of urban runoff.

The effects of adding mineral adsorbents and fine grains to porous concrete is tested for increasing its performance in improving the quality of urban runoff. Two levels of sand (10 and 20 per cent) and 5, 10 and 15 per cent of zeolite, perlite, LECA and pumice were added to the porous concrete. Unconfined compressive strength, hydraulic conductivity (permeability) and porosity of the porous concrete specimens were measured. Some of the best specimens were selected for testing the improvement of runoff quality. A rainfall simulator was designed and the quality of the runoff was investigated for changes in electrical conductivity (EC), total suspended solids (TSS), total dissolved solids (TDS) and chemical oxygen demand (COD).

The results of this study showed that compressive strength of the porous concrete was increased by adding fine grains to the concrete mixture. Fine grains decreased the permeability and porosity of the samples. Zeolite had the highest compressive strength. Samples having pumice own maximum permeability. Samples which had perlite, had the least compressive strength and permeability. Because of the fast flow of runoff water in the porous slab and its low thickness, sufficient time was not provided for effective functioning of the additives, and the removal percentage of the pollution parameters was low.

Porous concrete can ameliorate both quantity and quality of the urban runoff.

The total life and reliability of a fastened joint does not depend entirely upon the initial strength of the components involved but also upon the compatibility of the materials concerned with the service environment.

Digital technologies are widely used for digitization of museum and archival heritage and creation of digital, multimedia and online exhibitions, especially in terms of costume history. Digital exhibitions require historical dress forms which were used in the past for costume presentation. The purpose of this paper is to develop a new method for parametric modeling of the nineteenth century dress forms in accordance with fashionable body shape.

Due to limited number of body measurements in historical sizing tables, it is impossible to redesign the morphology of old fashionable body with high accuracy by means of contemporary CAD. The developed method is based on two sources of information: first, historical sizing tables with body measurements; second, historical corsets. By combining both resources and applying virtual try-on technology, the full anthropometric database about the nineteenth century fashionable body shape has been organized and the parametric model of historical dress form has been generated.

The digital replica of deformable parametric dress form was created automatically in accordance with the historical sizing systems and the corsets construction. The process of reproduction of a historical dress form has been done with high accuracy due to substantial advantages of contemporary software.

This study shows new way of anthropometric data generating from the construction of close-fitting and compression undergarments. The developed method and the new database can be applied for each type of dress forms which were used in the second part of the nineteenth century to generate its digital replica in virtual reality. The new approach is joining the digital technologies and the professional knowledge as an important part of cultural heritage for studying, recreating and presenting historical costume.

There is extensive literature on the determinants of job tenure insecurity. However, very little is known about the individual drivers of labour market insecurity. Additionally, while a piece of literature shows that volunteering improves workers' income, no study considers volunteering as an activity which could help workers to feel more confident about their perception of labour market insecurity if they lost or resigned their jobs. Therefore, purpose of this paper is to study whether workers who volunteer are less likely to perceive labour market insecurity.

The paper employs data from the sixth European working conditions survey which provides a great deal of information on working conditions. For the empirical investigation, probit model as well as robustness analysis have been implemented.

Results show that employees who do voluntary activities have a greater likelihood of declaring perceived labour market insecurity, which is nearly 3 percentage points lower, than employees who do not volunteer. Findings suggest that governments need to improve the relationship between for-profit and non-profit sectors to encourage volunteering.

This is the first study which considers volunteering as an activity which could help workers to feel more confident about their perception of “labour market insecurity”. Most of the studies on “labour market insecurity” do not focus on the workers individual characteristics but mainly on the labour markets institutional characteristics and welfare regimes differences.

Furthermore, key lessons learned and recommended teaching strategies are provided and future plans for application of cutting-edge technologies to education are described.

This study aims to examine the political, economic, social and technological (PEST) factors of women empowerment in the context of rural development under the initiatives of the National Rural Livelihood Mission (NRLM).

The unit of analysis for this study is 459 samples. Non-probability sampling technique has been used for this study. Schedule/questionnaires have been circulated among the women in each block cluster. Frequencies have been used to represent the data against each statement. Non-parametric chi-square test has been used to examine the relationship between empowerment and political, economic, social, technological factors and interpersonal skills.

Statistical analysis shows that the Deendayal Antayodaya Yojana (DAY)-NRLM scheme has brought significant changes and development to women in political, social, economic and technological areas. It was observed that women are economically empowered and contribute to the economic upliftment of the family. Most of the respondents strongly felt that after being associated with DAY-NRLM, they were empowered to contribute efficiently to the social development process and activities.

The findings of this study highlight the impact of DAY-NRLM implementation at block levels of a district in India. Subsequent research may be carried to measure the effectiveness of the capacity-building program conducted under the banner of DAY-NRLM.

Women empowerment is not limited to awareness, whereas it needs a complete set of initiatives backed with support systems. Few critical interventions could be building strong networks, enhancing financial management, encouraging the spirit of entrepreneurship among self-help group workers, providing easy access to credit, mentoring, handholding, continuous monitoring and evaluation.

This study focuses on the impact of the DAY-NRLM scheme on women’s empowerment in the Morigaon district. The inferences from the study throw light on the empowerment of women vis-à-vis political, economic, social and technological factors.

This study is a primary study conducted in the Morigaon District of Assam. This is a new line of policy research that approaches the women empowerment with the PEST parameters.
