Are the Rich REALLY as Mobile as Thought?

The view that the rich are highly mobile has gained much political traction in recent years and has become a central argument in debates about whether there should be "millionaire taxes" on top-income earners. But a new study dispels the common myth about the propensity of millionaires in the United States to move from high to low tax states.

"The most striking finding in our study is how little elites seem willing to move to exploit tax advantages across state lines," said Cristobal Young, an assistant professor of sociology at Stanford University and the lead author of the study. "Millionaire tax flight is occurring, but only at the margins of significance."

In any given year, Young and his fellow researchers found that roughly 500,000 individuals file tax returns reporting incomes of $1 million or more (constant 2005 dollars). From this population, only about 12,000 millionaires change their state each year. The annual millionaire migration rate is 2.4 percent, which is lower than the migration rate of the general population (2.9 percent). The highest rates of migration are seen among low-income tax filers: migration is 4.5 percent among people who earn around $10,000 a year.

"There is a widely held perception that elites are extremely mobile -- that they are more attached to money than to place, and with money you can live anywhere you want," said Young, who noted that millionaires are no less likely to live in states with high income taxes (e.g., New Jersey or California) than in states with low or zero income taxes (e.g., Texas or Florida). "We tend to think of migration as a form of freedom and one of the privileges enjoyed by the rich. In practice, migration comes with high social and economic costs -- uprooting one's family, breaking away from one's social networks, and restarting in a new place."

Cuckoldry: Jared Diamond got THIS Wrong, too

Despite the urban myth reinforced by many a daytime talk show, researchers writing in Trends in Ecology & Evolution on April 5 say the emerging evidence consistently indicates that very few fathers have unknowingly raised children who were not biologically their own. The collective evidence for low rates of extra-pair paternity (EPP) challenges the notion that it pays, evolutionarily speaking, to sleep around, the researchers say.

"Media and popular scientific literature often claim that many alleged fathers are being cuckolded into raising children that biologically are not their own," said Maarten Larmuseau of KU Leuven in Belgium. "Surprisingly, the estimated rates within human populations are quite low--around 1 or 2 percent."

Those rates apparently haven't changed much either, despite the fact that people in the past didn't have access to modern contraceptives.

2/3s of American Urban Farmers Have Motives Other Than Profit

Two thirds of urban farmers have a social mission that goes beyond food production and profits, finds new research led by NYU Steinhardt School of Culture, Education, and Human Development.

The study, published in the British Food Journal, shows that three of the four top reasons farmers grow in urban areas - food security, education, community building, and producing food for the market - have social motivations.

As urban populations grow in the United States, farming in cities is becoming more common. While food entrepreneurs seek to make money through urban farming, many urban farms are concerned with factors beyond food production, and have incorporated social goals into their missions. These missions align with a larger social movement in food - the "good food movement" - that focuses on where food comes from, who grows it, and how it's grown.

"Given the limited ability of urban farms in terms of food production, the social mission of urban farms arises as a possible explanation for the recent growth," said study author Carolyn Dimitri, associate professor of food studies at NYU Steinhardt.

In their study, Dimitri and her colleagues identified and analyzed the social missions of urban farms in the United States, and explored differences and similarities among farms with varying missions.

They analyzed data collected from a national survey of 370 urban farmers. Thirty-five questions, covering the 2012 farm year, addressed food production and marketing practices, risks and challenges, information and technical assistance needs, farm size and location, age of primary farmer, and farm characteristics.

The researchers found that food production is an essential part of the mission for all urban farms, but approximately two thirds of farmers surveyed also expressed a social mission. These social missions are primarily related to food security, education, and community building.

Murder in the Pleistocene! Lethal Interpersonal Violence Runs Deep in the Genus Homo

Lethal Interpersonal Violence in the Middle Pleistocene

Authors:

Sala et al

Abstract:

Evidence of interpersonal violence has been documented previously in Pleistocene members of the genus Homo, but only very rarely has this been posited as the possible manner of death. Here we report the earliest evidence of lethal interpersonal violence in the hominin fossil record. Cranium 17 recovered from the Sima de los Huesos Middle Pleistocene site shows two clear perimortem depression fractures on the frontal bone, interpreted as being produced by two episodes of localized blunt force trauma. The type of injuries, their location, the strong similarity of the fractures in shape and size, and the different orientations and implied trajectories of the two fractures suggest they were produced with the same object in face-to-face interpersonal conflict. Given that either of the two traumatic events was likely lethal, the presence of multiple blows implies an intention to kill. This finding shows that the lethal interpersonal violence is an ancient human behavior and has important implications for the accumulation of bodies at the site, supporting an anthropic origin.

Cities in the Past and the Present are the Same

Despite notable differences in appearance and governance, ancient human settlements function in much the same way as modern cities, according to new findings by researchers at the Santa Fe Institute and the University of Colorado Boulder.

Previous research has shown that as modern cities grow in population, so do their efficiencies and productivity. A city's population outpaces its development of urban infrastructure, for example, and its production of goods and services outpaces its population. What's more, these patterns exhibit a surprising degree of mathematical regularity and predictability, a phenomenon called "urban scaling."

But has this always been the case?

SFI Professor Luis Bettencourt researches urban dynamics as a lead investigator of SFI's Cities, Scaling, and Sustainability research program. When he gave a talk in 2013 on urban scaling theory, Scott Ortman, now an assistant professor in the Department of Anthropology at CU Boulder and a former Institute Omidyar Fellow, noted that the trends Bettencourt described were not particular to modern times. Their discussion prompted a research project on the effects of city size through history.

To test their ideas, the team examined archaeological data from the Basin of Mexico (what is now Mexico City and nearby regions). In the 1960s -- before Mexico City's population exploded -- surveyors examined all its ancient settlements, spanning 2000 years and four cultural eras in pre-contact Mesoamerica.

Using this data, the research team analyzed the dimensions of hundreds of ancient temples and thousands of ancient houses to estimate populations and densities, size and construction rates of monuments and buildings, and intensity of site use.

Neandertals had a Sexual Division of Labor

Neanderthal communities divided some of their tasks according to their sex. This is one of the main conclusions reached by a study performed by the Spanish National Research Council (CSIC), published in the Journal of Human Evolution. This study, which analyzed 99 incisors and canine teeth of 19 individuals from three different sites (El Sidron, in Asturias - Spain, L'Hortus in France, and Spy in Belgium), reveals that the dental grooves present in the female fossils follow the same pattern, which is different to that found in male individuals.

Analyses show that all Neanderthal individuals, regardless of age, had dental grooves. According to Antonio Rosas, CSIC researcher at the Spanish National Museum of Natural Sciences: "This is due to the custom of these societies to use the mouth as a third hand, as in some current populations, for tasks such as preparing the furs or chopping meat, for instance".

Rosas specifies that "what we have now discovered is that the grooves detected in the teeth of adult women are longer than those found in adult men. Therefore we assume that the tasks performed were different".

Other variables analyzed are the tiny spalls of the teeth enamel. Male individuals show a greater number of nicks in the enamel and dentin of the upper parts, while in female individuals these imperfections appear in the lower parts.

It is still unclear which activities corresponded to women and which ones to men.

Effects of Temperature and Precipitation on Violence on sub-Saharan Africa

Effects of temperature and precipitation variability on the risk of violence in sub-Saharan Africa, 1980–2012

Authors:

O’Loughlin et al

Abstract:

Ongoing debates in the academic community and in the public policy arena continue without clear resolution about the significance of global climate change for the risk of increased conflict. Sub-Saharan Africa is generally agreed to be the region most vulnerable to such climate impacts. Using a large database of conflict events and detailed climatological data covering the period 1980–2012, we apply a multilevel modeling technique that allows for a more nuanced understanding of a climate–conflict link than has been seen heretofore. In the aggregate, high temperature extremes are associated with more conflict; however, different types of conflict and different subregions do not show consistent relationship with temperature deviations. Precipitation deviations, both high and low, are generally not significant. The location and timing of violence are influenced less by climate anomalies (temperature or precipitation variations from normal) than by key political, economic, and geographic factors. We find important distinctions in the relationship between temperature extremes and conflict by using multiple methods of analysis and by exploiting our time-series cross-sectional dataset for disaggregated analyses.

Evolution of Cultural Traits Occurs at Similar Relative Rates?

Evolution of cultural traits occurs at similar relative rates in different world regions

Authors:

Currie et al

Abstract:

A fundamental issue in understanding human diversity is whether or not there are regular patterns and processes involved in cultural change. Theoretical and mathematical models of cultural evolution have been developed and are increasingly being used and assessed in empirical analyses. Here, we test the hypothesis that the rates of change of features of human socio-cultural organization are governed by general rules. One prediction of this hypothesis is that different cultural traits will tend to evolve at similar relative rates in different world regions, despite the unique historical backgrounds of groups inhabiting these regions. We used phylogenetic comparative methods and systematic cross-cultural data to assess how different socio-cultural traits changed in (i) island southeast Asia and the Pacific, and (ii) sub-Saharan Africa. The relative rates of change in these two regions are significantly correlated. Furthermore, cultural traits that are more directly related to external environmental conditions evolve more slowly than traits related to social structures. This is consistent with the idea that a form of purifying selection is acting with greater strength on these more environmentally linked traits. These results suggest that despite contingent historical events and the role of humans as active agents in the historical process, culture does indeed evolve in ways that can be predicted from general principles

Tracing Tongan Stone Tool Trade Yields Interesting Results

Stone tools from the ancient Tongan state reveal prehistoric interaction centers in the Central Pacific

Authors:

Clark et al

Abstract:

Tonga was unique in the prehistoric Pacific for developing a maritime state that integrated the archipelago under a centralized authority and for undertaking long-distance economic and political exchanges in the second millennium A.D. To establish the extent of Tonga’s maritime polity, we geochemically analyzed stone tools excavated from the central places of the ruling paramounts, particularly lithic artifacts associated with stone-faced chiefly tombs. The lithic networks of the Tongan state focused on Samoa and Fiji, with one adze sourced to the Society Islands 2,500 km from Tongatapu. To test the hypothesis that nonlocal lithics were especially valued by Tongan elites and were an important source of political capital, we analyzed prestate lithics from Tongatapu and stone artifacts from Samoa. In the Tongan state, 66% of worked stone tools were long-distance imports, indicating that interarchipelago connections intensified with the development of the Tongan polity after A.D. 1200. In contrast, stone tools found in Samoa were from local sources, including tools associated with a monumental structure contemporary with the Tongan state. Network analysis of lithics entering the Tongan state and of the distribution of Samoan adzes in the Pacific identified a centralized polity and the products of specialized lithic workshops, respectively. These results indicate that a significant consequence of social complexity was the establishment of new types of specialized sites in distant geographic areas. Specialized sites were loci of long-distance interaction and formed important centers for the transmission of information, people, and materials in prehistoric Oceania.

The Robopolapypse may get Parental Controls

Older adults' fears that companion robots will negatively affect young people may create design challenges for developers hoping to build robots for older users, according to Penn State researchers.

Companion robots provide emotional support for users and interact with them as they, for example, play a game, or watch a movie.

Older adults reported in a study that while they were not likely to become physically and emotionally dependent on robots, they worried that young people might become too dependent on them, said T. Franklin Waddell, a doctoral candidate in mass communications. Those surveyed also indicated that although they were not worried about being negatively affected by robots, the adults would still resist using the devices.

"We've seen this type of effect, which is usually referred to as a third-person effect, with different types of media, such as video games and television, but this is the first time we have seen the effect in robotics," said Waddell. "According to a third person effect, a person says they are not as negatively affected by the media as other people."

The researchers, who presented their findings today (April 30) at the Association for Computing Machinery's Conference on Human Factors in Computing Systems, said this effect could eventually lead to changes in behavior. For instance, people who believe video games harm young people may tend to avoid the games themselves. Likewise, older adults who believe that companion robots could harm young people may tend to avoid robots.

To compensate for the effect, robot designers may need to consider adding controls that will help adults monitor the use of robots by children, said Waddell, who worked with S. Shyam Sundar, Distinguished Professor of Communications and co-director of the Media Effects Research Laboratory, and Eun Hwa Jung, a doctoral candidate in mass communications.

"Robot designers and developers look at older adults as a central user base for companion robots," said Waddell. "This effect is something they should consider when designing the interface for the robots to make sure, for example, that the robot includes some type of parental controls."

Robots with parental controls may convince adults that they can own and use robots and still protect children from their fears that the devices might lead to laziness and dependency.

Programs to Move Families out of High-Poverty Neighborhoods Benefits Girls, not Boys

A program designed to move families out of high-poverty neighborhoods resulted in reduced rates of depression and conduct disorder among girls, but increased rates of depression, post-traumatic stress disorder (PTSD) and conduct disorder among boys, according to a study published in the March 5 issue of JAMA.

Prof. Jens Ludwig, one of the study's authors, said this was a follow-up long-term analysis of families participating in the Moving to Opportunity residential-mobility demonstration sponsored by the U.S. Department of Housing and Urban Development. Ludwig is the McCormick Foundation Professor of Social Service Administration, Law, and Public Policy at the University of Chicago; director of the UChicago Crime Lab; and co-director of the University of Chicago Urban Education Lab.

"The major surprise was the size of the findings," Ludwig said. "Moving out of high-poverty areas had very different effects on boys and girls, and both effects are large. For boys, the increase in PTSD is comparable to what you see from combat exposure among military veterans, while the reduction in depression among girls is equally massive."

Moving to Opportunity was designed to use housing vouchers to move families out of very distressed public housing projects into less disadvantaged neighborhoods with lower poverty and crime rates, with the goal of improving educational achievement and economic self-sufficiency. Between 1994 and 1998 the HUD program enrolled 4,604 volunteer low-income public housing families in five cities (Baltimore, Boston, Chicago, Los Angeles and New York) and randomly assigned some but not others to receive housing vouchers.

The follow-up evaluations were conducted 10 to 15 years later, which meant participants who were in early childhood at the time of the randomization were in adolescence when researchers were evaluating long-term associations of the housing mobility program with mental disorders. Ludwig's co-researchers on the study include lead author Ronald C. Kessler from Harvard Medical School as well as other colleagues from Harvard, University of California-Irvine, the National Bureau of Economic Research and the Congressional Budget Office.

The researchers found that girls whose families had the chance to move through Moving to Opportunity had much lower rates of major depression compared to the control group (6.5 percent versus 10.9 percent) and conduct disorder (0.3 percent versus 2.9 percent). On the other hand, boys whose families had the chance to move through Moving to Opportunity had significantly elevated rates of major depression (7.1 percent vs. 3.5 percent) and elevated rates of PTSD (6.2 percent versus 1.9 percent, respectively) and conduct disorder (6.4 percent vs. 2.1 percent).

What Happens When a Guaranteed Income is Provided for Poor Children?

Growing up poor has long been associated with reduced educational attainment and lower lifetime earnings. Some evidence also suggests a higher risk of depression, substance abuse and other diseases in adulthood. Even for those who manage to overcome humble beginnings, early-life poverty may leave a lasting mark, accelerating aging and increasing the risk of degenerative disease in adulthood.

Today, more than one in five American children live in poverty. How, if at all, to intervene is almost invariably a politically fraught question. Scientists interested in the link between poverty and mental health, however, often face a more fundamental problem: a relative dearth of experiments that test and compare potential interventions.

So when, in 1996, the Eastern Band of Cherokee Indians in North Carolina’s Great Smoky Mountains opened a casino, Jane Costello, an epidemiologist at Duke University Medical School, saw an opportunity. The tribe elected to distribute a proportion of the profits equally among its 8,000 members. Professor Costello wondered whether the extra money would change psychiatric outcomes among poor Cherokee families.

By age 23, 49% of black, 44 % of Hispanic & 38 % of White Males Arrested.

Nearly half of black males and almost 40 percent of white males in the U.S. are arrested by age 23, which can hurt their ability to find work, go to school and participate fully in their communities.

A new study released Monday (Jan. 6) in the journal Crime & Delinquency provides the first contemporary findings on how the risk of arrest varies across race and gender, says Robert Brame, a criminology professor at the University of South Carolina and lead author of the study.

The study is an analysis of national survey data from 1997 to 2008 of teenagers and young adults, ages 18󈞃, and their arrest histories, which run the gamut from truancy and underage drinking to more serious and violent offenses. The study excludes arrests for minor traffic violations.

Most striking are the race differences revealed in the study, Brame says. In particular, the research points to a higher prevalence of arrest among black males and little race variation in arrest rates among females.

"A problem is that many males – especially black males – are navigating the transition from youth to adulthood with the baggage and difficulties from contact with the criminal justice system," Brame says.

The negative impacts can be great, he says. "States vary on the age that adolescents are considered adults in the eyes of the criminal law, some as young as age 16 and 17," he says. "Criminal records that show up in searches can impede employment, reduce access to housing, thwart admission to and financing for higher education and affect civic and volunteer activities such as voting or adoption. They also can damage personal and family relationships."

Shawn Bushway, a criminal justice professor at the University at Albany who collaborated with Brame on the study, says they used data from the U.S. Department of Labor's National Longitudinal Survey of Youth, 1997 cohort (NLYS97).

The Future of Black and White

Interesting. Not that different than what I've heard otherwise.

Keep in mind that Benjamin Franklin's writings, he railed against the nonwhite immigrants moving into the US and corrupting its culture. Those immigrants? Germans. Yep. Germans. He considered the English, certain Germans (Saxons, iirc), Dutch and perhaps the Scots to be white. No one else was. 100 years ago, Italians and Irish were not "white" by general American social standards. They are definitely considered such today. What is 'white' and what is not is a moving standard. Dr Lee points that out in an interesting manner.

It appears that the definite of 'white' is moving to encompass asians and latinos. By 2035 or 2040, it may well be that being Mexican is no different than Italian. Or Irish. The differences would absorbed and some kept by society as a whole and some not, just like any other immigrant group in the past once the flow from the point of origin has slowed to a trickle. Had we still be getting waves of Italians from the late 19th century all the way to the present, our societal uneasiness might still be present.

Unfortunately, developments make it look like, as Dr Lee points out again, that white is going to be excluding black in the life trajectories of those within their categories. Listen to the short above. Its a bit depressing. Black is the underclass. Sad and depressing that.
