Symptoms And Signs

This article explores the different types of hair loss that black women may experience more than other groups of patients. Properties of African hair and the impact of hair care practices are discussed, as well as factors affecting the presentation of other hair loss conditions. It is important for the aesthetic practitioner to be able to distinguish between the temporary forms of hair loss that they can help to treat and the permanent or scarring forms of hair loss, which need a prompt referral to a dermatologist with a specialist interest in hair. Prompt recognition and referral can help to delay the progression of hair loss. The symptoms and signs that patients and practitioners should be alerted to are explored, as well as the treatments that can help and where referrals may be necessary. Recent developments and gaps in knowledge are summarised.

The Impact

There is evidence that greater aesthetic experience can be linked to artworks when their corresponding meanings can be successfully inferred and understood. Modern cultural-expo architecture can be considered a form of artistic creation and design, and the corresponding design philosophy may be derived from representational objects or abstract social meanings. The present study investigates whether cultural-expo architecture with an easy-to-understand architectural appearance design is perceived as more beautiful and how architectural photographs and different types of descriptions of architectural appearance designs interact and produce higher aesthetic evaluations. The results showed an obvious aesthetic preference for cultural-expo architecture with an easy-to-understand architectural appearance design (Experiment 1). Moreover, we found that the aesthetic rating score of architectural photographs accompanied by an abstract description was significantly higher than that of those accompanied by a representational description only under the difficult-to-understand design condition (Experiment 2). The results indicated that people preferred cultural-expo architecture with an easy-to-understand architectural appearance design due to a greater understanding of the design, providing further evidence that abstract descriptions can provide supplementary information and explanation to enhance the sense of beauty of abstract cultural-expo architecture.

Good Agreement

This paper presents an analysis of the situation in which a two-wheeler (i.e. a motorcycle, where the term motorcycles includes scooters) falls over to the side and then successively slides; this typically occurs in road accidents involving this type of vehicle. Knowing the deceleration rate of the sliding phase allows the kinetic energy dissipated and the speed of the motorcycle just before the fall to the ground to be calculated. These parameters are very important in the analysis and reconstruction of accidents. The work presented in this paper was developed in two experimental test sessions on fully faired motorcycles which are mainly of the scooter type and widely used in urban areas. In the first session, sliding tests were carried out, with the speed in the range 10–50 km/h, on three different types of road surface. Analysis of the evidence allowed the dissipative main phases of motion of the motorcycle (the impact with the ground, the rebounds and the stabilized swiping) to be identified and some factors affecting the phenomenon to be studied. The coefficient of average deceleration was calculated using two typical equations. The second test session consisted of drag tests. In these tests, the motorcycle, which had previously laid on its side, was dragged for a few metres at a constant speed of about 20 km/h, while the drag force was measured. A comparison of the results obtained in these tests with those obtained in the sliding tests yielded very good agreement in the coefficients of deceleration.

Structured Questionnaire

Purpose – The purpose of this paper is to compare the evaluations of various risks by young Israelis living in conflict area and their Polish counterparts, who do not live in conflict area and how these perceptions affect their traveling intentions to destinations with different types of risks – Egypt, Turkey, India and Japan. Design/methodology/approach – The research participants were 713 Israeli and Polish students who responded to a structured questionnaire. Findings – The findings validate the assumption that contextual distinctions shape differently factors affecting traveling risk estimation and the intention of young people to travel abroad. The results indicated that the priming effect is substantial, reflected in Israelis’ significantly higher assessments of risks concerning destinations with terror, health and natural disasters hazards in comparison to Poles’ evaluations. As predicted, Israeli students exhibit lesser intentions to travel to Turkey, Egypt and India than their Polish counterparts. The study also showed similarities between Israeli and Polish students. Young tourists’ with strong aversion to health hazards exhibit low intention to travel to India and those refraining from economic crisis are reluctant to travel to Egypt. The intention to travel to Japan and India decreased with high perception of destination risks. Originality/value – The current study constitutes a new departure in studying the contextual effects on travel-related decision making. It focusses on the impact of conflict ridden environment on intentions, attitudes and risks perception of young tourists with respect to traveling to risky destinations, previously hardly studied.

The Relationship

Vehicles that are non-roadworthy pose a hazard for all road users and can be one of the main causes of traffic accidents. Previous studies have analysed the impact of the driving style on environmental sustainability and road safety. Starting from this, there was a need to further investigate the relationship between the driving style and vehicle roadworthiness as well. Vehicles that do not comply with the prescribed requirements should be excluded from traffic at a periodic technical inspection. However, the causes of detected vehicle defects cannot be established at a periodic technical inspection. The paper therefore, examines the factors affecting vehicle roadworthiness. First, the failure rate and mileage of vehicles at periodic technical inspection regarding the type of ownership was examined. In addition, a questionnaire was conducted to collect data about the driving style and maintenance habits of different types of car owners. The paper argues that vehicles owned by legal entities were generally in a worse condition than the vehicles owned by natural persons, due to the increased vehicle exploitation, but also due to a more aggressive driving style. Finally, it was found that by modifying their driving style, the drivers can affect the condition of their vehicles, considering the same mileage and maintenance habits.

The Impact

To gain an understanding of the factors affecting the interaction of one grain with its environment as it reaches equilibrium, we study a particle bouncing off a flat surface. The bouncing of the particle leads to dissipation that is usually characterized with t, the coefficient of restitution, defined as the ratio between the velocity component that is normal to the contact surface just before impact (Vn) and the same component, but immediately after the collision (Vn’), i.e. related to a kinetic energy corresponding to motion in the normal direction. We will show how d is affected by energy stored in other degrees of freedom and transferred to kinetic energy that leads to an increase in normal velocity after the impact Vn’, and therefore to, ɛ >1. For this purpose, the evolution of potential, translational kinetic energy and rotational kinetic energy is analysed during the whole relaxation process and just before and after each collision for two different types of particle, a disk and a faceted particle.

Innovation Community

Different types of virtual innovation-related communities have emerged in recent years. These are increasingly being utilized by companies from different industries as a tool to efficiently source knowledge from diverse groups of individuals and thus to nourish internal innovations. Based on a case study research methodology this study investigated the impact 39 motivational factors have on the participation and contribution of members of two different innovation communities, i.e., an online Swiss innovation intermediary community (n = 48) and the off-line internal innovation community of a Swiss bank (n = 69). Results showed many similarities yet 16 significant differences between the perception of members of the two investigated innovation communities. For example, reward related items (monetary and non-monetary) showed to be top motivators for the intermediary community only. Items such as 'Webcam option', 'Chat function', 'Connection with other social network platforms', were perceived as low motivators by both communities. Derived from the findings, we discuss how the nature of the innovation community has an influence on the motivation and measures potentially leading to higher participation and contribution efficiency.

Background: Traction alopecia (TA) is a preventable form of hair loss that most commonly affects women. It is the result of chronic use of hairstyles that put tension on hair. Public health efforts to increase awareness of this condition are critical. Early recognition by health care providers, along with counseling and cessation of offending hair care practices can impact severity of hair loss. Objectives: In a patient with patchy hair loss, having a high index of suspicion for TA and looking for clues in the history and exam, can help establish an accurate diagnosis. Methods: Patients with afro-textured or curly hair may use various techniques to maintain their hairstyles while sleeping in order to avoid time-consuming and/or expensive hair care. This behavior is not commonly recognized or addressed. Results and Conclusions: Increased awareness of “nocturnal traction” and asking patients “How do you wear your hair when you sleep?” may help identify at-risk patients.
