Reducing the energy consumption of Indian iron and steel industry through enhancing energy efficiency: Role of regional coordination

This article aims at estimating the energy efficiency of the iron and steel industry in production theoretic approach. Taking a regional perspective, we have done a meta‐frontier analysis combined with the slack‐based measure of data envelopment analysis (DEA). The results depict huge energy efficiency gap exists across four regions. The northern region is the best performer under group frontier than meta‐frontier DEA. South and west regions are relatively well‐performed under meta‐frontier than group frontier while the eastern region performs moderately well under both frontiers. The results show the significant energy efficiency improvement opportunities available across regions can be realised through technological advancement and energy management.     

Sanctioning risky life-styles: Attitudes toward solidarity or equitable distribution of health care

Rising costs of medical care and increasing knowledge about behavior-related health risks favor the use of the equity principle in health care allocation. This paper deals with attitudes to the question of whether or not one's payments should be contingent upon the risks one takes. From an explorative analysis of arguments espoused by letter writers from a Dutch health magazine, it becomes apparent that equity plays a major role in the respondents' views of the distribution of health care facilities. Next, the role of attribution in adopting attitudes toward risky life-styles is studied on the basis of a survey using a representative sample of Dutch households. Beliefs about the individual ability to influence health have no effect on risk solidarity, whereas beliefs about the proper amount of effort to avoid health risks do have an effect.     

Identification and age estimation of blood stains on colored backgrounds by near infrared spectroscopy

Non-destructive identification and subsequent age estimation of blood stains are significant steps in forensic casework. The latter can provide important information on the temporal aspects of a crime. As previously shown, visible spectroscopy of blood stains on white backgrounds can successfully be used for their identification and age estimation. The use of this technique however, is hampered by dark backgrounds. In the present study the feasibility to use near infrared (NIR) spectroscopy was evaluated for blood stain identification and age estimation on dark backgrounds. Using NIR reflectance spectroscopy, blood stains were distinguished from other substances with 100% sensitivity and 100% specificity. In addition, Partial Least Squares Regression analysis was applied to estimate the age of blood stains on colored backgrounds. The age of blood stains up to 1 month old was estimated successfully with a root mean squared error of prediction of 8.9%. These findings are an important step toward the practical implementation of blood stain identification and age estimation in forensic casework, where a large variety of backgrounds can be encountered.     

法证科学领域的决策

随着法证DNA证据以及它所适用的概率模型日益凸显,反映了传统法证科学的局限性,并使人们对法证科学领域的决策产生了越来越多的质疑,焦点集中在对结论的解读方式和实际运用。分析表明,科学证据的本质不是绝对性或确定性的,而是概率性的;同时,事实审判者需要基于这些概率性的证据对事实作出明确的决定。因此,对于法证科学领域的决策,应当是专家在一系列归纳得出的特定假设基础上,就研究结果的概率进行恰当的报告,由事实审判者承担对概率作出决断的任务。     

Reforming Indian agriculture and the rise of farmer's protest in India: Tracing the discourse and the way ahead

The Indian government unveiled new farm legislation on September 27, 2020, with the goal of empowering the farming community. According to the government, new farm regulations will reduce the reliance of indigenous farmers on the mandi (market yard) system, which is now in place and is quite exploitative and full of middlemen and legal cartels. The regulations made contract farming lawful with the intention of luring private sector investment in bolstering agricultural supply chains and infrastructure to give farmers better pricing. But these rules are referred to as repressive and anti-farmer by the farming community. Farmers believe that eliminating the mandi system will eliminate the minimum support price (MSP) mechanism and that contract farming will ultimately be damaging, enticing major corporations and private investors to bind them to unfair contracts that will result in exploitation. Farmers' demonstrations have begun as a result in the former territory of the green revolution. In order to determine if the new farm regulations introduced by the central government are indeed beneficial to the rural community or not, the article followed the debate among many academics, policy makers, economists, researchers, stakeholders, and politicians (the government's spokesman). The article's main focus is on analysing the farmers' demand for the new farm rules to be repealed and the economic justification for their opposition. Additionally, it contends that new farm rules will encourage capitalistic farming and endanger the viability of farming communities, particularly small and marginal farms (S&M).     

Youth in Crisis: The Well-Being of Middle Eastern Youth and Adolescents During War and Peace

This study reports data of psychological well-being and self-esteem of Gaza Palestinian, Israeli Bedouin Arab, and Israeli Jewish adolescents during the time shortly before and after the signing of the Israeli-Palestinian Autonomy Agreement. The study is a partial follow-up to previous research examining the impact of violence, warlike conditions, and extreme social change on the mental health adjustment of adolescents of this region. Results of the Derogatis Symptom Checklist, revised and Coopersmith Self-Esteem Inventory showed the following: (a) psychopathology was significantly higher among Gaza youth, while Israeli Jewish and Bedouin youth showed lower levels; (b) youth from Gaza had the lowest levels of self-esteem, while there were no differences between Israeli Jewish and Bedouin youth; and (c) despite the long interval that had elapsed between the first (amid the Intifada) and second administrations (subsequent to the Oslo accords) of the measures, and the changing conditions, there was minimal evidence of change in levels of distress.     

Visualization of Latent Blood Stains Using Visible Reflectance Hyperspectral Imaging and Chemometrics

The detection of latent traces is an important aspect of crime scene investigation. Blood stains on black backgrounds can be visualized using chemiluminescence, which is invasive and requires a darkened room, or near-infrared photography, for which investigators need to change filters manually to optimize contrast. We demonstrated the performance of visible reflectance hyperspectral imaging (400–720 nm) for this purpose. Several processing methods were evaluated: single wavelength bands, ratio images, principal component analysis (PCA), and “SIMPLe-to-use Interactive Self-modeling Mixture Analysis” (SIMPLISMA). Using these methods, we were able to enhance the contrast between blood stains and 12 different fabrics. On black cotton, blood dilutions were visible with a minimal concentration of 25% of whole blood. The hyperspectral camera system used in this study is portable and wireless, which makes it suitable for crime scene use. The described technique is noncontact and nondestructive, so all traces are preserved for further analysis.
