In 1995, the Latina adolescent birth rate surpassed that of African Americans for the first time. This article investigates cultural and social factors affecting the initiation of sexual intercourse among Latina adolescent mothers in Los Angeles. The data are from life history interviews with forty young mothers and their partners conducted in 1994 to 1997. Results suggest that sexual intercourse is initiated within the context of the couple's developing relationship, and that the course of relationships is highly scripted. Men pressure for sex and women resist. Women should be ignorant about sex, but control access to intercourse. Sex is never discussed. Thus, it is unexpected, and contraception other than withdrawal is not used. This script places young Latinas at enormous risk for pregnancy and STDs.

AbstractThe Walnut Twig Beetle (WTB), Pityophthorus juglandis Blackman, is a small bark beetle native to Mexico and Southwestern USA recorded for the first time in Europe (NE Italy) in 2013. WTB attacks walnut (Juglans spp.) and wingnut trees (Pterocarya spp.) and is the vector of Geosmithia morbida Kolarík et al., a pathogen causing the thousand cankers disease (TCD). WTB and TCD represent a serious threat for walnut orchards in Europe. Spatiotemporal data of the WTB-TCD infestations recorded from an 8-year-long (2013–2020) monitoring conducted in 106 walnut orchards of NE Italy were used to develop a model in order to analyze: (i) the effective dispersal capacity of WTB, (ii) the factors affecting dispersal and (iii) the colonization risk of healthy walnut orchards. We registered a mean annual dispersal of 9.4 km, with peaks of about 40 km. Pest dispersal is affected by distance of suitable hosts from the nearest infested site, number of walnut orchards in the surroundings (both infested and healthy), orchard size and walnut species in the orchard. Using the model, it was also possible to calculate the colonization risk of a specific walnut orchard according to its characteristics showing, for instance, that a medium-size (5,000 trees) black walnut orchard located at 25 km from the nearest infested orchard has an infestation risk of about 50% of probability.

The strength of abrasive wheels is one of the key factors affecting the performance of abrasive machining. The paper discusses ways to improve the strength of abrasive wheels. The stress-state mathematical model presented herein is a generalization of the existing models. It is used herein to find for the first time that there are numerous optimal combinations of the elastic modulus and reinforcing material density, which result in the same minimum value of the objective function. It is found out that increasing the radius of the reinforcing component while also optimizing the mechanical properties of its material may increase the permissible breaking speed of the wheel several times. We herein present a regression equation and a nomogram for finding the optimal combination of control factors. Conventional methods for testing the mechanical properties of materials, which have been proven reliable for testing metals and alloys, are not as reliable for testing abrasive materials, as the test results they generate are not sufficiently stable or accurate. We therefore propose an alternative method that does not require any special equipment or special studies.

ABSTRACT Recent research has identified critical roles for microRNAs in a large number of cellular processes, including tumorigenic transformation. While significant progress has been made towards understanding the mechanisms of gene regulation by microRNAs, much less is known about factors affecting the expression of these noncoding transcripts. Here, we demonstrate for the first time a functional link between hypoxia, a well-documented tumor microenvironment factor, and microRNA expression. Microarray-based expression profiles revealed that a specific spectrum of microRNAs (including miR-23, -24, -26, -27, -103, -107, -181, -210, and -213) is induced in response to low oxygen, at least some via a hypoxia-inducible-factor-dependent mechanism. Select members of this group (miR-26, -107, and -210) decrease proapoptotic signaling in a hypoxic environment, suggesting an impact of these transcripts on tumor formation. Interestingly, the vast majority of hypoxia-induced microRNAs are also overexpressed in a variety of human tumors.

The aim of this study is to explore nursing students’ experiences with death and terminal patients during clinical education. A secondary analysis of qualitative data that were collected through 11 focus group interviews with nursing students was performed. Data obtained from the interviews were analyzed using thematic analysis. There were a total of 9 themes across 3 contexts. Data were grouped under the following themes: feelings experienced when encountering death for the first time, reactions to the first encounter with death, factors affecting the reactions to death, involvement in terminal patient care, being informed about the physical process that terminal patients are going through, students’ approach toward terminal patients and their relatives, health professionals’ approach toward terminal/dying patients/their relatives, changes in the ideas about death, and changes in the ideas about terminal/dying patients. The study shows a lack of guidance on the part of teachers who also avoid patients and families who are considered terminally ill.

This study attempts to appraise the dynamic forces at play in the shaping of Soviet foreign policy and to discuss some of the recent problems of international law and diplomacy as viewed by the U.S.S.R. In order to place Russia's recent tortuous foreign policy in its proper perspective, it is essential to begin with a résumé of the changing Soviet concepts of law, followed by a consideration of the economic factors influencing these concepts. The shifting line of recent Soviet foreign policy will be discussed in a later part of the article.Originally, the Soviet concept of law was predicated on transitional socialism; Soviet theorists argued that proletarian revolution has for the first time in history created a socialist state of workmen and peasants. “This is the highest type of state—that of the dictatorship of the proletariat.” Having emerged victorious, the working class destroyed the oppressive, bourgeois state machinery and built a new state apparatus of its own. The new form of state, discovered by Lenin, is the Soviet Republic. The task of the workers is further to strengthen the dictatorship of the proletariat.

The measurement of skin electrical resistance (SER) has drawn a great deal of attention for the rapid screening of transdermal penetration enhancers (PEs). However, the mechanisms underlying the SER measurement are still unclear. This study was to investigate the effects and mechanisms of seven oxygen-containing terpenes on the SER kinetics. Stratum corneum (SC) lipids were proved to play a key role in SER measurement. Then, the factors affecting the SER measurement were optimized. By the determination of SER kinetics, cyclic terpenes (1,8-cineole, terpinen-4-ol, menthol and α-terpineol) were demonstrated to possess higher enhancement ratio (ER) values compared with linear terpenes (linalool, geraniol and citral). For the first time, the linear correlation was found between ER of terpenes and the interaction energy of terpene–ceramide complexes revealed by molecular simulation. The attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) analysis revealed that the effect of cyclic terpenes on SC lipid arrangement was obviously stronger than that of linear terpenes. In addition, by evaluating HaCaT skin cell viability, little difference was found between the toxicities of cyclic and linear terpenes. In conclusion, measurement of SER could be a feasible approach for the efficient evaluation of the PEs that mainly act on SC lipids.

This paper examines the factors affecting adolescent motherhood in Bangladesh using the 2007 Bangladesh Demographic and Health Survey data. Overall, 69.3 per cent of the married adolescents began childbearing. Among them 56.4 per cent were already mothers and 12.9per cent were pregnant for the first time. Of the adult married women age 20–49, 62.1 per cent initiated childbearing before age 19. The multiple logistic regression analyses revealed that women’s education, husband’s education, place of residence, ever use of contraceptive method, religion, wealth and region are important determinants of adolescent motherhood in Bangladesh.

A new spectrophotometric method for determinating trace amounts of fluoride has been introduced in this article. The principle of the method is based on the reaction of fluoride with a complex of aluminum ion and xylenol orange reagent (Al-XO). The concentration of fluoride in water is determined by measuring the red color of the Al-XO complex at 555 nm or measuring the yellow color of the XO reagent at 430 nm. The factors affecting the method for the determination of fluoride were examined. At the optimum condition, the limit of quantitation of this method is 0.08-2.1 mg/L. Based on an analysis of fluoride in the actual samples, the error of the method is less than 6%. A new point of this article is that this is the first time the type of calibration curve graph A = f (logC) in the spectrophotometric method (where: A – absorption; log - logarithm; C – concentration of fluoride) has been used in the world.
