Urban heat islands" occur when cities replace natural land cover with dense concentrations of pavement, buildings, and other surfaces that absorb and retain heat. This effect increases energy costs (e.g., for air conditioning), air pollution levels, and heat-related illness and mortality.

On this page, employers seeking to hire temporary nonimmigrant workers under the H-2A visa classification can find the AEWRs covering the agricultural labor or services to be performed. This information will assist employers in understanding their potential wage obligations to workers and preparing job orders (Form ETA-790/790A) for review by the State Workforce Agencies (SWAs) and OFLC. The terms State and statewide include the 50 States, the District of Columbia, Guam, Puerto Rico, and the U.S. Virgin Islands. Read additional background information on the AEWRs and how they are adjusted each year.

The Department understands that agricultural employers play a vital role in our nation's economy and that obtaining a reliable workforce is critical to producing the U.S. food supply. The Department is also bound by its statutory mandate to protect workers in the U.S. from adverse effects on their wages or working conditions resulting from hiring foreign workers. AEWRs are the minimum hourly wage rates that must be offered and paid by employers to H-2A workers and workers in corresponding employment. As provided in 20 CFR part 655, subpart B, the OFLC Administrator establishes the nationwide monthly AEWR for range occupations governed by the procedures in 20 CFR 655.200 through 655.235 and statewide hourly AEWRs for all other occupations.

The OFLC Administrator adjusts the AEWR for range occupations annually based on the Employment Cost Index (ECI) for wages and salaries published by the BLS. See 20 CFR 655.211(c). An employer seeking to employ foreign workers under the H-2A program is required to offer, advertise in its recruitment, and pay a wage that is at least equal to the AEWR when it is the highest applicable wage rate among the wage sources applicable to the employer's job opportunity. For range occupations, the wage offered and paid to H-2A workers and workers in corresponding employment must equal or exceed the monthly AEWR, the agreed-upon collective bargaining wage, or the applicable minimum wage imposed by Federal or State law or judicial action, whichever is highest. See 20 CFR 655.210(g) and .211(a).

The OFLC Administrator adjusts the hourly AEWRs for all other occupations at least annually, as provided in 20 CFR 655.120(b). An employer seeking to employ foreign workers under the H-2A program is required to offer, advertise in its recruitment, and pay a wage that is at least equal to the AEWR when it is the highest applicable wage rate among the wage sources applicable to the employer's job opportunity. For non-range occupations, the wage offered and paid must equal or exceed the hourly AEWR, the prevailing wage rate (if available), the Federal minimum wage, the State minimum wage, or the agreed-upon collective bargaining rate, whichever is highest. See 20 CFR 655.120(a) and .122(1).

Remembering the difference between the words can be especially hard because these senses of the words have just about the same pronunciation. Complicating things further is the fact that effect can also be used as a verb (meaning to make happen, as in We can only effect change by taking action) and affect can also be used as a noun (referring to a state of emotion, as in He had a sad affect). However, these senses of the words are much less commonly used.

Placebos won't lower your cholesterol or shrink a tumor. Instead, placebos work on symptoms modulated by the brain, like the perception of pain. Placebos may make you feel better, but they will not cure you. They have been shown to be most effective for conditions like pain management, stress-related insomnia, and cancer treatment side effects like fatigue and nausea.

How placebos work is still not quite understood, but it involves a complex neurobiological reaction that includes everything from increases in feel-good neurotransmitters, like endorphins and dopamine, to greater activity in certain brain regions linked to moods, emotional reactions, and self-awareness. All of it can have therapeutic benefit. The placebo effect is a way for your brain to tell the body what it needs to feel better.

But placebos are not all about releasing brainpower. You also need the ritual of treatment. When you look at these studies that compare drugs with placebos, there is the entire environmental and ritual factor at work. You have to go to a clinic at certain times and be examined by medical professionals in white coats. You receive all kinds of exotic pills and undergo strange procedures. All this can have a profound impact on how the body perceives symptoms because you feel you are getting attention and care.

A study published in Science Translational Medicine explored this by testing how people reacted to migraine pain medication. One group took a migraine drug labeled with the drug's name, another took a placebo labeled "placebo," and a third group took nothing. The researchers discovered that the placebo was 50% as effective as the real drug to reduce pain after a migraine attack.

The researchers speculated that a driving force beyond this reaction was the simple act of taking a pill. People associate the ritual of taking medicine as a positive healing effect. Even if they know it's not medicine, the action itself can stimulate the brain into thinking the body is being healed.

While these activities are positive interventions in their own right, the level of attention you give can enhance their benefits. The attention and emotional support you give yourself is often not something you can easily measure, but it can help you feel more comfortable in the world, and that can go a long way when it comes to healing.

A study published online by PLOS Biology may have identified what goes on in the brain during a placebo effect. Researchers used functional magnetic resonance imaging to scan the brains of people with chronic pain from knee osteoarthritis. Then everyone was given a placebo and had another brain scan. The researchers noticed that those who felt pain relief had greater activity in the middle frontal gyrus brain region, which makes up about one-third of the frontal lobe.

The average age of the population is rising worldwide. As a result, the prevalence of age-related conditions and time spent living with age-related morbidity1, including muscle loss and cognitive decline, are increasing. The prevalence of dementia is growing globally2, but as the population ages, recognition of cognitive changes that can happen as part of healthy ageing3 will become increasingly crucial for researchers and clinicians working with older people. Exercise can slow muscle loss and cognitive decline4,5. There are many reasons why older people may struggle to undertake exercise regimens, which, given their known efficacy for improving health and function, presents a challenge. Interventions that clearly demonstrate provide a broad array of physical and mental benefits are thus needed.

Skeletal muscle mass is regulated by the processes of muscle protein synthesis and breakdown (MPS and MPB). MPS rates are largely controlled by responsiveness to anabolic stimuli, including food consumption and physical activity. Catabolic stressors include illness, physical inactivity, and inflammation, of which older people tend to have higher rates. The aetiology of anabolic resistance is complex, involving ageing physiology and physical inactivity. Studies of protein supplementation for muscle function have displayed the most convincing results when combined with resistance exercise8. Resistance exercise is well established as a potent anabolic stimulus for skeletal muscle, with protein and exercise displaying a synergistic effect when used in combination9,10,11.

Prebiotics are food components that are selectively utilised by the gut microbiome to improve health24. Administration of a prebiotic food supplement has been shown to improve two of the Fried frailty criteria, namely hand grip strength and exhaustion25 and overall frailty index level26, in older adults. In addition, evidence is growing for the gut-brain axis, including preliminary evidence of a beneficial effect of prebiotic supplementation on cognition27. Thus, the gut microbiota may represent a malleable therapeutic target for the prevention and reversal of muscle loss with age and age-associated decline in cognition. No prior studies have investigated the effects of a supplement containing both protein and prebiotics on physical and cognitive function in older people. Genetic and environmental factors also impact physical and cognitive function, and randomising within twin pairs removes variance attributable to shared factors, enabling a more powerful study. To our knowledge, no other studies have investigated the effects of protein and prebiotic supplements in a twin population.

This study aims to assess whether the modulation of the gut microbiome using a prebiotic improves muscle function (as measured by 5 chair rise time, a marker of muscle strength) versus a placebo in a trial where all participants receive a protein (branched chain amino acids [BCAA]) and resistance exercise intervention. The study was designed to test whether the addition of gut microbiome modulation could augment established muscle function improvements from combined BCAA and exercise. The secondary outcomes were cognition, grip strength, short physical performance battery, appetite, and gut microbiome measures. The use of twins, who are matched so closely for both genetic and environmental factors, strengthened the study design.
