Technicians still need to retune and reassemble the piano. The work is not done when the strings are set. Technicians must have the strength and finesse required to place the new strings effectively, as well as the patience to complete the process. Mishandling the strings can send them flying across the room. These strings do not bend easily, and they are also more likely to break in the process. Piano strings are made of solid steel, and they are thicker in diameter than what you would use on a guitar or other string instruments. Adding New StringsĪdding new strings is often a wrestling match for technicians, and the process is often compared to wrangling a snake. Replacing with larger pins is essential for holding the new string properly. If a piano reaches the point where it needs to be restrung then odds are the pins have loosened over time and created larger holes in the pin block. Passing over them several times gives the piano a chance to adjust to the changes in pressure.Īfter they are loosened enough the technician can clip the strings and get started replacing the old tuning pins. While this is essential to produce the correct note with a good tone, it creates a sensitive situation for technicians to navigate.Ĭlipping a string while it is tight releases over 100 lbs of tension at once, which is more than enough to damage the piano or injure the technician. The typical piano holds over 30,000 lbs of pressure on the strings. Once all the strings are exposed they need to be loosened over several passes. After this, they will remove the entire front of the instrument, including: ![]() In an upright piano, this requires the technician to flip the piano on its back. The technician starts by exposing all the strings in the piano. The process requires patience, dedication, and a wealth of knowledge. Technicians have a series of steps that they must follow carefully to restring the piano effectively without causing any damage. If you have seen the process for restringing a piano, you might have an idea of everything that is involved. ![]() The labor involved in restringing a piano goes well beyond what might be involved in restringing another instrument, such as a guitar, and the cost reflects this challenge.

Previous studies in the US have indicated that first-born adolescents are more likely to have higher self-esteem than other siblings and only children ( 18), whereas middle-born adolescent males are found to have lower self-esteem ( 19). Further, happiness is known to be one of the indicators based on an individual's hedonistic view or emotional well-being, which suggests positive affectivity and satisfaction with life ( 17). Resilience ( 12) and self-esteem ( 13) can be considered important aspects of positive mental health ( 14– 16). Positive mental health refers to a state of subjective well-being and functioning well ( 11). There is a lack of empirical studies to investigate the associations in non-Western countries, including Japan. Further, most of the previous studies were conducted in Western countries. To date, however, few epidemiological studies have examined whether birth order is associated with mental health problems among children, particularly, pre-adolescent children. These circumstances have adverse effects on mental health throughout sensitive development periods in childhood, which might last across the life course. These include later-born children being more likely to have limited interactions with parents, less parental attention, and diluted available home resources ( 9, 10). ![]() There are several considerations underling the mechanisms of the associations. These findings from Western countries have indicated later-born have an increased risk of mental health problems. Similarly, prior register-based studies have reported that later-born adults aged 16 years are at a higher risk of suicidal behavior in Norway and Sweden ( 7, 8). A population-based study in the UK has shown that later-born adolescents are more likely to have suicide attempts and psychiatric problems ( 6). Previous research has shown that later-born children aged 7–12 years in the US have been found to have a higher level of depression and anxiety ( 5). To reveal this situation, it is crucial to understand risk and protective factors for prevention of mental illness in adolescence and adulthood. Japan is not exception for example, the number of suicide among children and adolescents has gradually increased over a decade ( 3), ranked second in Asia, followed by Korea ( 4). In addition, half of the cases of lifetime mental health problems begin by the age of 14 ( 2). There is an increasing number of mental health problems among adolescents, with 10–20% of them estimated to suffer from these problems in the world ( 1). Further research is warranted to elucidate the mechanism of the association between birth order and the development of behavior problems and the positive aspects such as resilience, happiness, and self-esteem among children. These associations were similar in the adjusted model and dichotomized outcomes model.Ĭonclusions: Differential impacts of birth order on child mental health, for both positive and negative sides, were found. Self-esteem score did not differ by sibling types. The lowest happiness score was found among middle-borns. Resilience score was also highest among last-borns, followed by first-borns, middle-borns, and only children. The highest prosocial behaviors score was found among last-borns ( p < 0.001). Results: Last-borns showed the lowest total difficulties score in the SDQ, while only children showed the highest ( p < 0.001). The analysis was controlled for child sex, mother's age, mother's education, caregiver's depressive symptoms, household income, and living with grandparents. Multiple regression analysis for continuous outcomes and logistic regression for dichotomous outcomes were used to examine the association of birth order with mental health problems, resilience, happiness, and self-esteem. Parent-rated Strengths and Difficulties Questionnaire (SDQ) and self-rated resilience, happiness, and self-esteem score were used to assess child mental health. Methods: This was a cross-sectional study using data from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study, which was a population-based study of children in fourth grade in public schools in Adachi City, Tokyo, Japan in 2018 ( N = 3,744). ![]() Objective: This study aimed to investigate the association of birth order with mental health problems, self-esteem, resilience, and happiness among children aged 9–10 years. 2Department of Health and Welfare Services, National Institute of Public Health, Saitama, Japan. ![]() 1Department of Global Health Promotion, Tokyo Medical and Dental University, Tokyo, Japan.Yoshifumi Fukuya 1 Takeo Fujiwara 1 * Aya Isumi 1 Satomi Doi 1 Manami Ochi 2 ![]() You can use this to fill forms when you don't want to give your real telephone.

She says it’s common for camouflage to work both near and far, in different ways: “This idea of a two-stage protection is quite well-established.” For example, from afar, poison dart frogs blend into their environment. Tombak’s evidence doesn’t rule out the possibility that the stripes might play interesting tricks from afar, according to Anna Hughes, a psychologist at the University of Essex who has studied how predators perceive zebra stripes. “Selection from many other sources can impact that trait.” “Once you’ve got stripes, you’ve got this anti-fly effect,” he says. Additional variation could come from random genetic drift, or separate adaptations meant to confuse predators. That, of course, begs the question of why zebras have stripes of different widths-but Ted Stankowich, an evolutionary ecologist from California State University Long Beach who was not involved in the work, says all that really matters is that zebras have them. Instead, she says, her team’s results show that “within the range of stripe widths that occurs naturally in zebras, width doesn’t make that much of a difference.” But, she says, only a couple of previous studies examined stripe width, and they rarely involved real pelts one tested painted stripes up to 5 inches wide, which is beyond what any real zebra has. Narrower stripes should create an even stronger barber pole illusion-“an enhanced perceived speed effect" as Tombak puts it-and thus stronger repulsion. And it makes sense that this illusion works close-up, as the fly is on approach to land. “You can imagine for a moving fly, just tons of objects are passing by at a very fast rate,” she says. A zebra’s stripes, she thinks, create a similarly disorienting sense of movement, which should make it harder for flies to gauge the timing and speed for a smooth landing. It creates a false perceived direction of motion, and false speed as well. “Outside of a barber shop, there’s that rotating pole that looks like it’s going up, but it’s just rotating,” says Tombak. And while they can sense motion and polarized light and process images 10 times faster than our eyes, those images are very low-res.īut like you, flies get fooled by the “barber pole” illusion-that famous diagonal red stripe that seems to spiral infinitely upwards. Flies have “compound eyes” that combine input from thousands of photoreceptors, each pointing in slightly different directions from their eye’s rounded surface. Why does it work? First, it’s helpful to know that flies don’t see the world as you do. And over the 100 rounds, the team found no obvious difference between stripes of different widths. The flies chose the impala skin about four times as often as they chose either zebra skin. It could be thermoregulation,” says Tombak. It could be some kind of social adaptation to help zebras recognize each other. Ecologists have long scratched their heads about what evolutionary advantage could support such a conspicuous change. In African landscapes that are green, brown, blue, and yellow, painting your butt with sharp streaks of black and white seems like a death wish. In fact, the fact that zebras have stripes at all is still sort of a surprise. “That was a surprise because previous studies had indicated that there might be a difference,” says Tombak, who is currently a postdoctoral researcher at Hunter College. They also found that narrow zebra stripes don’t repel flies any better than wider ones. Tombak’s team agrees there is an illusion-but since they restricted the flies to a 4-foot-wide box, they argue that the mechanism happens up close, not from afar.

He declined to discuss what such a deal might fetch, saying that is for the consultant to report back to the board. While the center has used the name Greater Columbus Convention Center under the theory that what it was selling to potential visitors was the city of Columbus itself, the financial strain caused by the ongoing COVID-19 pandemic has caused it to rethink that strategy, Brown said.
