The aim of the research is to estimate the level of the early career gender wage gap in Russia, its evolution during the early stages of a career, gender segregation and discrimination among university graduates, and to identify factors which explain early career gender differences in pay. Special emphasis is placed on assessing the contribution of horizontal segregation (inequal gender distribution in fields of studies and industries of employment) to early-career gender inequality.

The study is based on a comprehensive and nationally representative survey of university graduates, carried out by Russian Federal State Statistics Service in 2016 (VTR Rosstat). The authors use Mincer OLS regressions for the analysis of the determinants of gender differences in pay. To explain the factors which form the gender gap, the authors use the Oaxaca-Blinder and Neumark gender gap decompositions, including detailed wage gap decompositions and decompositions by fields of study. For the analysis of differences in gender gap across wage distribution, quantile regressions and quantile decompositions based on recentered influence functions (RIFs) are used.

The study found significant gender differences in the early-career salaries of university graduates. Regression analysis confirms the presence of a 20% early-career gender wage gap. This gender wage gap is to a great extent can be explained by horizontal segregation: women are concentrated in fields of study and industries which are relatively low paid. More than half of the gender gap remains unexplained. The analysis of the evolution of the gender wage gap shows that it appears right after graduation and increases over time. A quantile decomposition reveals that, in low paid jobs, females experience less gender inequality than in better paid jobs.

The analysis has some important policy implications. Previously, gender equality policies were mainly related to the elimination of gender discrimination at work, including positive discrimination programs in a selection of candidates to job openings and programs of promotion; programs which ease women labour force participation through flexible jobs; programs of human capital accumulation, which implied gender equality in access to higher education and encouraged women to get higher education, which was especially relevant for many developing countries. The analysis of Russia, a country with gender equality in access to higher education, shows that the early career gender gap exists right after graduation, and the main explanatory factor is gender segregation by field of study and industry, in other words, the gender wage gap to a high extent is related to self-selection of women in low-paid fields of study. To address this, new policies related to gender inequality in choice of fields of studies are needed.

It has been frequently stated that gender inequality appears either due to inequality in access to higher education or after maternity leave. Using large nationally representative dataset on university graduates, we show that gender equality in education does not necessarily lead to gender equality in the labour market. Unlike many studies, we show that the gender gap in Russia appears not after maternity leave and due to marital decisions of women, but in the earliest stages of their career, right after graduation, due to horizontal segregation (selection of women in relatively low-paid fields of study and consequently industries).

This study aims to investigate the effect of bismuth addition (up to 30 Wt%) on the microstructure and electrical conductivity of a commercial lead-free alloy (SAC405) near the solder/substrate soldered joint. The system under study is referred in this work as (SAC405 + xBi)/Cu, as Cu is the selected substrate in which the solder was casted. The electrical resistivity of this system was investigated, considering Bi addition effect on the local microstructure and chemical composition gradients within that zone.

Solder joints between Cu substrate and SAC405 alloy with different levels of Bi were produced. The electrical conductivity along the obtained solder/substrate interface was measured by four-point probe method. The microstructure and chemical compositions were evaluated by scanning electron microscopy/energy dispersive spectroscopy analysis.

Two different electrical resistivity zones were identified within the solder interface copper substrate/solder alloy. At the first zone (from intermetallic compound [IMC] until approximately 100 μm) the increase of the electrical resistivity is gradual from the substrate to the solder side. This is because of the copper substrate diffusion, which established a chemical composition gradient near the IMC layer. At the second zone, electrical resistivity becomes much higher and is mainly dependent on the Bi content of the solder alloy. In both identified zones, electrical resistivity is affected by its microstructure, which is dependent on Cu and Bi content and solidification characteristics.

A detailed characterization of the solder/substrate zone, in terms of electrical conductivity, was done with the definition of two variation zones. With this knowledge, a better definition of processing parameters and in-service soldered electronic devices behavior can be achieved.

In a printed circuit board assembly (PCBA), the coefficient of thermal expansion (CTE) mismatch between the solder joint materials has a detrimental impact on reliability. The mechanical stresses caused by the thermal changes of the assembly lead to fatigue and sometimes the failure of the solder joints. The purpose of this study is to propose a novel pad design to obtain an interrupted solder/substrate interface, to improve the PCBA reliability.

An interruption in the continuous intermetallic compound (IMC) layer of a solder joint was implemented, by the deposition of a silicone film in the pad, changing its geometry. That change allows a redistribution of stresses in the most ductile zone of the solder joint, the solder. The stress concentration at the solder/substrate interface is reduced, as well as the general state of stress at the solder joint.

A new way was developed to reduce the stress on the solder joints, caused by thermal variations, because of the different components CTEs mismatch. This new method consists of interrupting the IMC layers of the solder joint, strategically, redirecting the usual stresses to a more ductile area of the joint, the solder. This is an innovative method that allows increase the lifetime of PCBAs and the equipments.

In this study, a new pad design concept for higher solder joint reliability was developed to reduce the shear stress in the solder joints because of the CTE mismatch between all the solder joint components.

Development studies rarely measure the impact of value chain strategies on performance. The purpose of this paper is to quantify the perceived contribution of strategies to the performance of three honey value chains in Brazil.

The value chain structure-conduct-performance (SCP) framework was used to select strategies and two performance indicators, honey production growth and local value-added. In a conjoint study, experts were asked to judge the contribution to the two performance indicators of several hypothetical combinations of value chain strategies.

According to the experts, adoption of specialised technical assistance, sharing resources at the production step, increase in exports, and organic certification were the strategies which contributed the most to performance. Simulations suggested that some honey value chains could have greatly increased their performance with these higher pay-off strategies.

Quantifying the perceived impact of individual strategies contributes to improved evaluation of development interventions.

Outcomes also show that conjoint analysis is a useful method for policy evaluations in data scarce situations.

The paper combines an extended SCP framework for strategy selection and conjoint analysis for strategy evaluation of value chains.

This article aims to understand the influences surrounding the consumption of fragrances, especially if these products fit as a brand extension of luxury brands. More specifically, it aims at identifying the main reasons behind the process of buying fragrances and the main features associated with the consumption of fragrances.

This research adopts a qualitative approach in the form of 15 in-depth interviews with consumers of fragrances, seeking to assess attitudes and influences in the consumption of fragrances as a brand extension of luxury brands.

This research shows that the emotional use of fragrances as a luxury product is much more important than their functionality, the relationship between the studied consumers and fragrances depends on the occasion of consumption (season of the year; day or night) and the aroma and the durability of the aroma is the main decision criterion for the purchase of fragrances. Respondents have also mentioned comfort, elegance and sophistication as attributes to choose a fragrance as a luxury product.

This article adds to the current knowledge on the topics of luxury brand management and buying behaviour by providing a better understanding of attitudes and influences towards the use of fragrances. This research recognizes the importance of a brand extension strategy for luxury brands, especially in the case of fragrances.

The purpose of this study was to investigate the relationship between parenting styles, family psychological vulnerability environment (FPVE) and drug use among adolescents.

The quantitative survey using paper and pencil was administered to collect data from 284 parents registered with a paediatric clinic in the city of São Paulo (Brazil), most of whom claimed that their children used drugs. FPVE was measured by eight scales: family relationship patterns and drug use habits; hereditary predisposition to drug use; transmission of moral values to children (reverse); parents’ hereditary predisposition; parental drug use; depression; impulsiveness; and anxiety.

Dimensions of FPVE that had effect on drug use by adolescents were: the family relationship and drug use patterns of the family of procreation, drug use by the parents and heredity in relation to drug use. Conversely, the family relationship and drug use patterns of the family of origin and the parents’ anxiety, symptoms of depression and impulsiveness did not affect their children’s drug use.

One limit of this study is the sample of parents. These parents were parents of adolescents that were at psychological treatment. The authors do not know if part of parents who declared that their children are not drug users, because the treatment effect. Another limit is that this study did not compare the effect of parents’ drugs misuse with parents that do not use drugs on adolescent drug use. One other limit is that the parents were treated regardless of whether they were mothers or fathers.

This study expands the study of the antecedents of drug use by adolescents, considering FPVE as a construct. Regarding this construct when facing resources limitation, the practitioners can prioritize strategies to prevent adolescent drug use.

Current literature provides limited insights into the supply chain contexts within which e-commerce can create higher value for firms. To address this literature gap, this research explores the value potential, and thus value creation process, of e-commerce initiatives for supply chain distribution channel expansions.

Using secondary data collected from multiple sources, this research conducted an event study to examine the stock market reactions to the announcements of e-commerce initiatives of Chinese firms.

The results indicate that the e-commerce initiatives increase average firm value by CNY 295.29 million in a three-day window around the initiative's announcement date. Moreover, we find that such stock market reactions are more positive for firms with poor operating performance, and more negative when firms deploy initiatives on their own (rather than third-party) platforms. Further, companies that integrate or complement their online sales with an offline sales channel experience more positive stock market reactions.

This study provides new insights into the value creation process of e-commerce from an operation and supply chain process perspective.

Global participation in higher education has expanded greatly since the late twentieth century. The implications for the cultural, social, and economic fabric of societies have been substantial. To explain transitions from elite to mass higher education systems, theoretical insights from Technical-functionalism, Neo-institutionalism, World Academic System, and Credentialism perspectives have been put forward. It is the contention of this paper that there are emerging and complementary factors driving steadily growing participation in “high-income” universal higher education systems. The paper aims to discuss these issues.

With reference to Ulrich Beck’s concept of the “risk society”, it is discussed how higher education participation is increasingly a response by young people (and their families) seeking to mitigate heightened instability in work and employment under a “risk regime”. Publicly available data from national and supra-national organisations are used to evidence trends and support the arguments put forward by this paper.

Participation is perceived as quasi-compulsory to “survive” amid concern that those without higher education attainment are being “left behind” in modern labour markets. This environment has contributed to more students from more diverse backgrounds viewing higher education as the only viable option to secure a livelihood regardless of rising private costs of participation and rising uncertainty over graduate employment outcomes. The expansion of higher education has therefore potentially developed a self-perpetuating dynamic as the perceived cost of non-participation escalates.

It is shown that to better understand higher education participation in “high-income” countries with universal higher education systems, one needs to consider the conceptual idea of “survivalism”, that underlines risk and the vulnerabilities of modern societies.
