Objectives of cosmetology therapy include restoration and regeneration, anti-inflammatory effects, the strengthening of blood vessels and regulation of their permeability, and the regulation of keratinization. Vascular abnormalities can be targeted with specific light and laser devices. Therefore, the present paper aims to review the latest advances and summarize different aspects concerning skin care in rosacea. Particular attention has been paid to the co-operation of cosmetologists with other specialists in order to bring about the interdisciplinary management of rosacea. It is also important to keep in mind that it is usually necessary to combine various methods of treatment, as this approach is more effective than monotherapy for attaining satisfactory cosmetic results in rosacea patients.

This paper analyzes interviews with African American women cosmetologists who collaborated in designing and implementing a series of community-centered science, technology, engineering, and mathematics (STEM) education programs to support broadening the participation of Black children in those fields. These collaborations used technologies and media as bridges between STEM knowledge as it appears in schools and STEM knowledge as it has been and is communicated, produced, and used by Black hair care experts. We discuss how acknowledging these experts as knowledge producers who have unique pedagogical expertise not only provides new ways for reimagining STEM fields for Black children, but also helps to acknowledge STEM's existing and generative presence in Black communities. Our findings reveal three ways that this group of African American cosmetologists helped reimagine STEM education: 1) STEM as personal and situated; 2) STEM as a blend of public and community institutions and 3) STEM as community.

The paper presents the results regarding the phytomonitoring of physiological processes in hair plants. Among the physiological processes that characterize the activity of the production process is photosynthesis, which, like other physiological processes, is influenced by light, temperature and other ecological factors. Based on these considerations, the saturation curve of the light for photosynthesis was monitored. The modern RTM-48A phytomonitor was used, which allowed the measurement of physiological indices in the form of film-phytodiagram in automatic regime that allowed the diagnosis of the properties of the genotype and the physiological state of the plants. The saturation curve of light for photosynthesis in hair trees was determined as a result of assessing the intensity of photosynthesis, sweating, respiration and conductivity of stomata depending on temperature, humidity and CO2 content in air. The minimum value of the light at which the photosynthesis process is initiated was established. With the increase of the light intensity (to 1/3 of the total light) the intensity of the photosynthesis increases after the essential optimization of the process took place. In hair plants, the intensity of photosynthesis begins with the appearance of light and continues to increase until the illumination of 100-150 micromol / m2 s, decreasing to 500 after maintaining at the same level until the illumination of 1500, then it increases to 1800. It was been established that the effect of temperature influence on photosynthesis in hair plants depended on the intensity of light. Respiration, transpiration and conductivity of the stomata confirmed light saturation curves for photosynthesis. As a result of the research, the positive influence of SBA Reglalg and microelements (B, Zn, Mn, Mo) on the activity of physiological processes in hair plants was established. The more pronounced stimulation of the activity of the physiological processes takes place under the influence of the Reglalg preparation in the presence of microelements. [ABSTRACT FROM AUTHOR]

This paper investigates two channels of prosociality: indirect reciprocity and charitable giving. We conducted a natural field experiment in a hair salon in Hamburg, Germany, over the course of four months. In the baseline, we collected data on customers' tips-a scenario absent indirect reciprocity and donations. In two treatments we had the hairdresser collect donations to a charity. In one treatment the hairdresser pointed out the opportunity to donate. Our data indicate that the voluntary activity of collecting donations in the salon led to greater tips for the hairdresser and significant donations. In the second treatment, the hairdresser unconditionally donated to the charity before the customers could. This donation did not increase tips further compared with the collection-only treatment. Our data indicate that indirect reciprocity works in the field. We find evidence that indirect reciprocity and charitable giving work as complements. Data, as supplemental material, are available at . This paper was accepted by Uri Gneezy, behavioral economics. [ABSTRACT FROM AUTHOR]

In a recent paper, Hod started a study on no scalar hair theorem for asymptotically flat spherically symmetric neutral horizonless reflecting compact stars. In fact, Hod's approach only rules out massive scalar fields. In the present paper, for massless scalar fields outside neutral horizonless reflecting compact stars, we provide a rigorous mathematical proof on no hair theorem. We show that asymptotically flat spherically symmetric neutral horizonless reflecting compact stars cannot support exterior massless scalar field hairs. [ABSTRACT FROM AUTHOR]

We study the effect of the reduction in the VAT rate on hairdresser services from 17.5 to 6% in the Netherlands in January 2000. Following Kosonen (J Public Econ 131:87-100, 2015), we use differences-in-differences to estimate the effects of this reform, with beauty salons as the main control group. In our preferred specification, we find close to full pass-through of the VAT cut into lower prices. However, we find no statistically or economically significant effect on the volume of sales or employment. [ABSTRACT FROM AUTHOR]

The instinct to tame and preserve and the longing for eternal beauty makes skin a crucial element in the genre of the Body Horror. By applying a gendered reading to the art of destruction and reconstruction of an ephemeral body, this paper explores the significant role of skin that clothes a protean body in Almodóvar's unconventional Body Horror, "The Skin I Live In" (2011). Helpless vulnerable female bodies stretched on beds and close shots of naked perfect skin of those bodies are a frequent feature in Almodóvar films. Skin stained and blotched in "Tie Me Up! Tie Me Down!" (1989), nurtured and replenished in "Talk to Her" (2002), patched up and stitched in "The Skin I Live In", becomes a key ingredient in Almodóvar's films that celebrate the fluidity of human anatomy and sexuality. The article situates "The Skin I Live In" in the filmic continuum of Body Horrors that focus primarily on skin, beginning with Alfred Hitchcock's "Psycho" (1960), and touching on films like Jonathan Demme's "The Silence of the Lambs" (1991) and Tom Tykwer's "Perfume: The Story of a Murderer" (2006) and attempts to understand how the exploited bodies that have been culturally and socially subjugated have shaped the course of the history of Body Horrors in cinema. In "The Skin I Live In" the destruction of Vicente's body and its recreation into Vera follow a mad scientist's urge to dominate an unattainable body, but this ghastly assault on the body has the onscreen appearance of a routine surgical operation by an expert cosmetologist in a well-lit, sanitized mise-en-scène, suggesting that the uncanny does not need a dungeon to lurk in. The exploited body on the other hand may be seen not as a passive victim, but as a site of alterity and rebellion. Anatomically a complete opposite of Frankenstein's Creature, Vicente/Vera's body, perfect, beautiful but beset with a problematized identity, is etched with the history of conversion, suppression, and the eternal quest for an ephemeral object. Yet it also acts as an active site of resistance. [ABSTRACT FROM AUTHOR]

As aging populations continue to grow, primarily in developed countries, there are increasing demands for the system that monitors the activities of elderly people while continuing to allow them to pursue their individual, healthy, and independent lifestyles. Therefore, it is required to develop the activity of daily living (ADL) sensing systems that are based on high-performance sensors and information technologies. However, most of the systems that have been proposed to date have only been investigated and/or evaluated in experimental environments. When considering the spread of such systems to typical homes inhabited by elderly people, it is clear that such sensing systems will need to meet the following five requirements: (1) be inexpensive; (2) provide robustness; (3) protect privacy; (4) be maintenance-free; and, (5) work with a simple user interface. In this paper, we propose a novel senior-friendly ADL sensing system that can fulfill these requirements. More specifically, we achieve an easy collection of ADL data from elderly people while using a proposed system that consists of a small number of inexpensive energy harvesting sensors and simple annotation buttons, without the need for privacy-invasive cameras or microphones. In order to evaluate the practicality of our proposed system, we installed it in ten typical homes with elderly residents and collected the ADL data over a two-month period. We then visualized the collected data and performed activity recognition using a long short-term memory (LSTM) model. From the collected results, we confirmed that our proposed system, which is inexpensive and non-invasive, can correctly collect resident ADL data and could recognize activities from the collected data with a high recall rate of 72.3% on average. This result shows a high potential of our proposed system for application to services for elderly people. [ABSTRACT FROM AUTHOR]

Acne vulgaris is one of the most common skin diseases in adolescence, causing a significant negative impact on the quality of life of young people who -- in a large percentage of cases -- do not accept their appearance. The complex pathogenesis of this disease requires appropriate preventive and curative treatment from both a dermatologist and a cosmetologist. The aim of the study was to discuss the methods currently used by dermatologists in local therapy for mild and intermediate forms of acne vulgaris, and to provide an overview of possible preventive and caring activities in the cosmetologist's office. Possible directions of cooperation between the dermatologist and the cosmetologist in the prevention of acne relapse and treatment of possible acne complications were also discussed.

The economic effects of occupational licensing remain an understudied topic, but even less is known about the effects of the removal of licensing legislation. In this article, we take advantage of a natural experiment that occurred in the state of Alabama. Alabama was the last state to begin licensing barbers in 1973 and also the only state to de‐license barbers (in 1983). Relying on data from 1974 to 1994, we find evidence that barber de‐licensing reduced the average annual earnings of barbers as well as the number of cosmetologist employees per million residents in Alabama, although not all our results are statistically significant. We also find evidence that de‐licensing resulted in small increases in the number of barber shops and decreases in the number of cosmetology shops in Alabama. In recent decades, a number of attempts have been made to re‐license the occupation — most recently with a barber licensing bill that became law in September 2013. The result is that barbering in Alabama is once again a licensed occupation. Our limited evidence suggests that the re‐licensing of barbers in Alabama may already have had an effect on pay and on the number of barber shops. [ABSTRACT FROM AUTHOR]
