Vacancy-mediated structural changes in Au–Cu nanoparticles

We report the formation of new phases in bimetallic Au–Cu nanoparticles. These phases were observed in nanoparticle synthesised by adopting a three-step protocol in a single pot. Nanoparticles at 180°C for 1?h led to the formation of single-phase solid solution of Cu in Au. Subsequent heat treatment at 290°C for 2?h of these Au–Cu nanoparticles revealed three new phases. One of them relates to the modification of occupancy of Cu in an ordered AuCu tetragonal phase (tP4). This cell although retains tetragonal symmetry but displays metrical properties akin to that of a cube. The other two relates to vacancy ordering along <111> directions in the {111} planes of an ordered AuCu3 cubic phase (cP4). On the one hand, statistical occupancy of vacancy on Cu site in this cell leads to the reduction of cell size from ～3.75?Å to ～3.5?Å whereas ordering of vacant layer on the other hand gives rise to symmetry breaking. Former continues to display cubic symmetry whereas latter transforms to a trigonal cell.     

Are Quantitative Skills Critical for Business Education Program or an Entry-Barrier for Diversity?

Two prominent criticisms of business education programs are that they disproportionately focus on cultivating quantitative skills (i.e., the ability to use and analyze numerical/mathematical concepts) and that the programs lack diversity in terms of gender, social class, and undergraduate backgrounds of students. We tested whether the emphasis on quantitative skills is linked to this lack of diversity in business education programs. We drew data from a Master of Business Administration (MBA) program from a leading business school in India (N?=?275). We analyzed three key outcomes (entrance test scores, program grades, and salary offers) for three attributes (gender, social class, and quantitative undergraduate degree) before and after partitioning of the quantitative and non-quantitative components of the academic outcomes. Before the partitioning of components, our regression models explained 63% of variance in entrance test scores, 42% in program grades, and 21% in salary offers, which was suggestive of the suitability of our predictor variables. Post-partitioning of the outcomes into quantitative and non-quantitative components, the key results were: (a) social class disadvantage was in both the quantitative and non-quantitative components of the entrance test, and in course grades; (b) female-disadvantage was in the quantitative coursework of the MBA program, but not in the entrance test, or in salary offers (p?<?.05); (c) individuals with a quantitative undergraduate education had no advantage in the quantitative section of the entrance test, or of the coursework; (d) social class, gender, and quantitative undergraduate had no effect on salary offers. However, salary offers were higher for those with work experience (p?<?.01), and most notably, for those who performed well in the non-quantitative courses (p?<?.01). On addressing lack of diversity, the results suggest that unlike individuals from a more marginalized social class, females’ deficit is selective and identifiable in the form of lower scores on the quantitative component of MBA coursework. Apart from identifying entry-barriers for diversity, our results are also helpful in discarding certain unfounded beliefs surrounding business education. For example, contrary to popular belief, quantitative undergraduate training has no advantage in business education. Moreover, quantitative course grades are not disproportionately valued in the job market for MBAs.     

Mean Girls: Provocative Clothing Leads to Intra-Sexual Competition between Females

This study aimed to investigate indirect aggression between females from an evolutionary perspective, considering indirect aggression as a mechanism of intra-sexual competition. Previous research suggests that females who are dressed provocatively, or appear ‘sexually available’, are more likely to be victims of indirect aggression from other females. Investigating this notion via an empirical measure and a word-selection task, this study involved a female confederate posing as a participant, who was dressed provocatively in one condition and conservatively in the other. Sixty-five females completed an intra-sexual competition scale and a word selection task in which they were able to select complimentary or derogatory phrases to describe the confederate. Making derogative comments is a common form of indirect aggression; therefore, those who selected derogatory phrases could be considered to be exhibiting indirect aggression. Consistent with our hypotheses, females in the provocative condition obtained significantly higher intra-sexual competition scores, selected more derogatory words, and less complimentary words than those in the conservative condition, indicating that females dressed provocatively are indirectly aggressed against to a greater extent than those that are not. This paper adds further support to the notion that indirect aggression is used by females as a method of intra-sexual competition, particularly towards provocatively dressed females.     

Influence of Profession as Risk of STIs in Intimate Partner Relationship in South Asian Countries

Mixing of sexual partners as part of the profession of female sex workers (FSWs) can be a risk in intimate partner relationship, which is primarily based on love and affection. Sexual relation with one partner provides emotional and psychological support. However, when it is a web of partners, it often results in unprotected sex, consequently creating a pathway for disease and increasing the vulnerability of FSWs to sexually transmitted infections (STIs). This paper analyses the subtleties of sexual behavior of FSWs and their vulnerability toward STIs in intimate partner relationship in South Asian countries. The basic data used in this paper have been taken from 3 countries, 1271 FSWs from Bangladesh, 1404 FSWs from Nepal, and 7399 FSWs from India. The data were collected through modified time location cluster sampling as a part of mapping and size estimation of most-at-risk populations (MARPs) in Nepal and key affected populations (KAPs) in Bangladesh during the period of 2010–2016. The data for India are taken from the integrated behavioral and biological assessment (IBBA), which assesses the prevalence of high risk population in India. The findings reveal that the majority of the FSWs were married, which reveals dynamics of sexual activity placing them at higher risk of STIs. About half of the FSWs had more than 15 coituses in the last 30 days in Nepal, which is a high risk factor. Unprotected sex is reported high across all three countries irrespective of all background characteristics. Condom use during intercourse in Bangladesh is less likely in older FSWs and more likely among educated FSWs who had coital frequency of 7 or more in the last 30 days. Interestingly, unmarried FSWs in Nepal are less likely to use condom in their last sex as against India where FSWs are more likely to use condom in their last sex. The prevalence of STI among uneducated FSWs is found higher in Bangladesh as compared to Nepal and India. The socio-demographic background characteristics showed a significant association with unprotected sex, coital frequency and prevalence of STI across all three countries.

Human Genome Editing and Ethical Considerations

Editing human germline genes may act as boon in some genetic and other disorders. Recent editing of the genome of the human embryo with the CRISPR/Cas9 editing tool generated a debate amongst top scientists of the world for the ethical considerations regarding its effect on the future generations. It needs to be seen as to what transformation human gene editing brings to humankind in the times to come.     

Analysing applications of neuromarketing in efficacy of programmatic advertising

In this paper, there is exploration of the concept of neuromarketing as a newly developed strategy with economic potential deriving from human brain research. The central notion of the essay is that programmatic advertising can be used to better comprehend the idea of neuromarketing and its impact on consumers' decision-making. So neuromarketing involves the scientific observation of brainwave activity, eye tracking, and skin response to determine how people's brains react to advertisements and other brand-related communications. By studying the brain, these neuromarketing strategies can forecast how consumers will make decisions. The neuromarketing tactics' benefits and constraints are studied on a number of market input devices in the paper. The influence of various techniques of neuromarketing is studied from the available research studies and literature. In the recent years, the neuromarketing concept has been able to garner a lot of importance in its contribution to the marketing, advertising, and programmatic advertising has been immensely helped by the understanding of consumer decision making. The consumer behaviour has been able to be comprehended through neuromarketing techniques which are one of the key pillars of the purpose and running of programmatic advertising. A neuromarketing study shall be the helping hand for increasing customer base, market leadership, and converting them to loyal customers. It will help in programmatic advertising through the understanding of the advertiser with respect to the likes and wants of the customers and how consumer attention can be drawn. The consumer behaviour can be understood by the marketers in terms of how the consumers react to the advertising.
