Many people argue that history makes a special difference to the subjects of biology and psychology, and that history does not make this special difference to other parts of the world. This paper will show that historical properties make no more or less of a difference to biology or psychology than to chemistry, physics, or other sciences. Although historical properties indeed make a certain kind of difference to biology and psychology, this paper will show that historical properties make the same kind of difference to geology, sociology, astronomy, and other sciences. Similarly, many people argue that nonhistorical properties make a special difference to the nonbiological and the nonpsychological world. This paper will show that nonhistorical properties make the same difference to all things in the world when it comes to their causal behavior and that historical properties make the same difference to all things in the world when it comes to their distributions. Although history is special, it is special in the same way to all parts of the world.  相似文献

Over the past decade, US states have responded to federal inaction on comprehensive immigration reform by increasing their output of immigrant policies, both beneficial and restrictive. Although there is a growing empirical literature focused on predicting such activity by states, less is known, especially on a broad scale, about the state-level consequences associated with the policy tone states adopt toward immigrants. To better understand the consequences of restrictive immigrant policies, we created a restrictive score for each state year between 2005 and 2014 and employed linear regression with panel-corrected standard errors to investigate effects on immigrant-related demographics, economic factors, and political participation. We found that states with higher restrictive policy tones do experience reductions in the number of foreign-born residents, including Hispanics and those with limited English proficiency, a goal of many state legislators who favor restrictive policies. States with restrictive policy tones showed reductions in unemployment and poverty rates as well, which are also professed goals for restrictive policy activity. Mediation analyses suggested that the effects of restrictive policy scores on economic conditions are indirect, being exerted through the percentage of a state’s population that is foreign born. Finally, though much attention is focused on the expected increase in Latino political clout, restrictive policy tone was not predictive of increased voter registration or voting in states that pass these types of policies. If anti-immigrant policies are inducing those who oppose these policies to mobilize politically, it must be in an arena outside of voting.  相似文献

We use classical test theory (CTT) and item response theory (IRT) methodologies to examine the psychometric and measurement properties of an instrument designed to assess sexual orientation harassment among military personnel (N?=?71,989). CTT analyses indicated that items were unidimensional and exhibited adequate levels of reliability. IRT analyses demonstrated that the items functioned similarly and exhibited appropriate levels of item discrimination. However, the analyses also suggested that the sensitivity of the items may be limited. Differential test functioning analyses provided evidence of the measurement equivalence of the instrument across male and female respondents. The findings provide support for the psychometric properties and measurement equivalence of the instrument for measuring sexual orientation harassment among male and female military personnel. We discuss the implications of our findings for future research on sexual orientation harassment in the workplace.  相似文献

In humans, eight monosaccharides are required for the synthesis of glycoproteins. Dietary supplements that supply these crucial sugars are known as glyconutrients. A glyconutrient compound was added to Peripheral Blood Mononuclear Cells (PBMC) isolated from normal controls and patients with the Chronic Fatigue Syndrome (CFS), a disease associated with immune dysregulation. The in vitro immunomodulatory effects were investigated. Cell surface expression of the glycoproteins CD5, CD8, and CD11a were significantly lower in patients with CFS compared to normal controls. Addition of glyconutrient homogenate to PBMC from patients with CFS stimulated with phytohemagglutinin significantly increased the expression of each glycoprotein. Furthermore, natural killer (NK) cell function was reduced in CFS patients. The glyconutrient preparation significantly enhanced NK cell activity versus human herpes virus 6 (HHV-6)-infected H9 cells in an 8 h51Cr release assay compared to placebo for PBMC from patients with CFS (p<.01). Finally, apoptosis was significantly higher in patients with CSF. The percentage of apoptotic cells was significantly decreased in PBMC from patients with CFS that had been incubated for 48 h with glyconutrients. Thus, glyconutrients improved abnormal immune parameters in vitro in patients with CFS. Dr. See is an Independent Mannatech Associate.  相似文献

Affordances are design clues that allow users to effortlessly determine how objects should be used. Since their introduction to the human–computer interaction design community, their use within interfaces has become a staple. But, despite work to understand how affordances make an interface's available actions transparent, few empirical studies have examined the cognitive origins of this interaction type. Therefore, we explored the impact of cognitive load on affordance‐based interactions. Participants were asked to perform a series of affordance‐based interactions while under different types of working memory load (no load, verbal, spatial, and central executive). Affordance‐based interactions were consistently slowed under central executive load, but never when under verbal load. We conclude that affordance‐based interactions do require cognitive resources, but resource costs may only manifest under heavy load. With this knowledge, designers may be able to better predict when an affordance will (or will not) act as if it is resource free. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

In akrasia, an agent intentionally acts against her own judgment about what it is best to do. This presents many puzzles for the understanding of human motivation. The Socrates of Plato's Protagoras, for example, denies this is possible because he claims that all action is motivated by an agent's belief about what is best. Plato himself seems to reject this view in the Republic, appealing to three distinct sources of motivation. This paper takes Plato's side in the general debate, arguing for a new tripartite moral psychology. Because the akratic acts for a reason but against the conclusion of her practical reasoning, there must be a way of acting for reasons other than through reasoning about them. This way is desire. But once there is a division between reason and desire, a third capacity is needed to solve conflicts that can arise between them, the will.  相似文献
