Is American democracy in crisis?

The Federal shutdown may be the most striking evidence to support claims that America’s political system is broken, but it is far from the only example. Writing in Governance, acclaimed political scientists Norman Ornstein and Jared Diamond explore if tribalism is at the heart of the problem, or if the U.S. is facing a far greater political crisis.

“The state of our overall political process as the most dysfunctional I have seen in over 44 years of watching Washington and American politics up close,” writes Norman Ornstein, from the American Enterprise Institute. “If we are not in the most dysfunctional period in our history, we are certainly in the top five.”

American political history has recorded many inept and ineffectual congresses, from the scandals of the 1970′s to the divided house of the 1860′s, so what makes the 112th and 113th congresses any different? Ornstein argues that the rise in political extremism, manifested in open tribalism, is to blame.

From acts seeking to tighten the rules over gun ownership, to commissions established to tackle America’s debt problem, the list of legislation that has been sunk by tribalism continues to grow into President Obama’s second term.

“Political dysfunction has serious consequences for the health, well-being, and future prospects for the country that go well beyond gridlock or political gamesmanship,” concluded Ornstein. “American history suggests that these problems are cyclical, that eventually we will come out of it and restore a modicum of problem-solving rationality. But ‘eventually’ does not mean anytime soon.”

In contrast, Jared Diamond, writing from the University of California, proposes that the United States is facing four existential threats to its democratic system.

“Our form of government is a big part of the explanation why the United States has become the richest and most powerful country in the world,” said Diamond. “Hence, an undermining of democratic processes in the United States means throwing away one of our biggest advantages.”

Diamond argues that political compromise has been deteriorating in recent decades, that restrictions on voting are reversing the positive historical trend of political enfranchisement, that the gap between rich and poor continues to grow, and that public spending by the government In areas such as education is declining.

“Large segments of the American populace deride government investment as ‘socialism,’ but it is not socialism. On the contrary, it is one of the longest established functions of government,” said Diamond.

Biological impacts of fracking still largely unknown

As production of shale gas soars, the industry’s effects on nature and wildlife remain largely unexplored, according to a study by a group of conservation biologists published in Frontiers in Ecology and the Environment on August 1.

The report emphasizes the need to determine the environmental impact of chemical contamination from spills, well-casing failure, and other accidents.

“We know very little about how shale gas production is affecting plants and wildlife,” says author Sara Souther, a conservation fellow in the Department of Botany at the University of Wisconsin-Madison. “And in particular, there is a lack of accessible and reliable information on spills, wastewater disposal and the chemistry of fracturing fluids. Of the 24 U.S. states with active shale gas reservoirs, only five maintain public records of spills and accidents.”

The 800 percent increase in U.S. shale gas production between 2007 and 2012 is largely due to the use of hydraulic fracturing. Also called fracking, the process uses high-pressure injection of water, laden with sand and a variety of chemicals, to open cracks in the gas reservoir so natural gas can flow to the well. A similar technique is used for extracting oil from “tight” geologic formations.

The chemical makeup of fracturing fluid and wastewater, which can include carcinogens and radioactive substances, is often unknown. The authors reviewed chemical disclosure statements for 150 wells in three top gas-producing states and found that, on average, two out of three wells were fractured with at least one undisclosed chemical.

Pressured by growing concern about pollution to groundwater and surface water, government and the industry have made some steps toward openness, Souther acknowledges, but she says more progress is needed.

“The Pennsylvania Department of Environmental Protection’s website is one of the nation’s best sources of publicly available information on spills of fracking fluid, wastewater, and other contaminants. Even so, gas companies failed to report over one third of spills in the last year,” she says. “How many more unreported spills occurred, but were not detected during well inspections? We need accurate data on the release of fracturing chemicals into the environment before we can understand impacts to plants and animals.”

One of the greatest threats to animal and plant life identified in the study is the cumulative impact of rapid, widespread shale development, with each individual well contributing collectively to air, water, noise and light pollution.

“The past has taught us that environmental impacts of large-scale development and resource extraction, whether coal plants, large dams or biofuel monocultures, are more than the sum of their parts,” notes Morgan Tingley, a researcher from University of Connecticut. “We can’t let shale development outpace our understanding of its environmental impacts.”

“If you look down on a heavily fracked landscape,” Souther says, “you see a web of well pads, access roads, and pipelines creating islands out of what was, in some cases, continuous habitat. What are the combined effects of numerous wells and their supporting infrastructure on wide-ranging or sensitive species, like the pronghorn antelope or the hellbender salamander?

“I am from West Virginia, which is underlain by one of the largest shale gas reservoirs in the U.S. However, this industry doesn’t just impact gas-producing states. Here in Wisconsin, shale development is affecting areas that supply sand for use in hydraulic fracturing.”

The study looked broadly at what is known – and what is not – about the conservation impacts of fracking. “Some of the wells in the chemical disclosure registry were fractured with fluid containing 20 or more undisclosed chemicals,” says co-author Kimberly Terrell, a researcher at the Smithsonian Conservation Biology Institute. “This is an arbitrary and inconsistent standard of chemical disclosure.”

With shale gas production projected to increase exponentially over the next 30 years, the authors hope the study will guide the application of limited scientific resources to the most important questions, and enhance cooperation among scientists, industry and policymakers to minimize damage to the natural world.

Potential ‘universal’ blood test for cancer discovered

Researchers from the University of Bradford, UK, have devised a simple blood test that can be used to diagnose whether people have cancer or not.

The test will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures such as colonoscopies and biopsies being carried out. Alternatively, it could be a useful aid for investigating patients who are suspected of having a cancer that is currently hard to diagnose.

Early results have shown the method gives a high degree of accuracy diagnosing cancer and pre-cancerous conditions from the blood of patients with melanoma, colon cancer and lung cancer. The research is published online in the FASEB Journal, the US Journal of the Federation of American Societies for Experimental Biology.

The Lymphocyte Genome Sensitivity (LGS) test looks at white blood cells and measures the damage caused to their DNA when subjected to different intensities of ultraviolet light (UVA), which is known to damage DNA. The results of the empirical study show a clear distinction between the damage to the white blood cells from patients with cancer, with pre-cancerous conditions and from healthy patients.

Professor Diana Anderson, from the University’s School of Life Sciences led the research. She said: “White blood cells are part of the body’s natural defence system. We know that they are under stress when they are fighting cancer or other diseases, so I wondered whether anything measureable could be seen if we put them under further stress with UVA light. We found that people with cancer have DNA which is more easily damaged by ultraviolet light than other people, so the test shows the sensitivity to damage of all the DNA – the genome – in a cell.”

The study looked at blood samples taken from 208 individuals. Ninety-four healthy individuals were recruited from staff and students at the University of Bradford and 114 blood samples were collected from patients referred to specialist clinics within Bradford Royal Infirmary prior to diagnosis and treatment. The samples were coded, anonymised, randomised and then exposed to UVA light through five different depths of agar.

The UVA damage was observed in the form of pieces of DNA being pulled in an electric field towards the positive end of the field, causing a comet-like tail. In the LGS test, the longer the tail the more DNA damage, and the measurements correlated to those patients who were ultimately diagnosed with cancer (58), those with pre-cancerous conditions (56) and those who were healthy (94).

“These are early results completed on three different types of cancer and we accept that more research needs to be done; but these results so far are remarkable,” said Professor Anderson. “Whilst the numbers of people we tested are, in epidemiological terms, quite small, in molecular epidemiological terms, the results are powerful. We’ve identified significant differences between the healthy volunteers, suspected cancer patients and confirmed cancer patients of mixed ages at a statistically significant level of P<0.001. This means that the possibility of these results happening by chance is 1 in 1000. We believe that this confirms the test’s potential as a diagnostic tool.”

Professor Anderson believes that if the LGS does prove to be a useful cancer diagnostic test, it would be a highly valuable addition to the more traditional investigative procedures for detecting cancer.

A clinical trial is currently underway at Bradford Royal Infirmary. This will investigate the effectiveness of the LGS test in correctly predicting which patients referred by their GPs with suspected colorectal cancer would, or would not, benefit from a colonoscopy – currently the preferred investigation method.

The University of Bradford has filed patents for the technology and a spin-out company, Oncascan, has been established to commercialise the research.

Bigger government makes for more satisfied people, international Baylor study finds

People living in countries with governments that spend more on social services report being more contented, according to a Baylor University study.

“The effect of state intervention into the economy equals or exceeds marriage or employment status – two traditional predictors of happiness – when it comes to satisfaction,” said Patrick Flavin, Ph.D., assistant professor of political science in Baylor’s College of Arts & Sciences.

The study – “Assessing the Impact of the Size and Scope of Government on Human Well-Being” – is published in the journal Social Forces. The researchers analyzed data from 21 advanced industrialized countries collected by the World Values Survey from 1981 to 2007, with nearly 50,000 respondents.

The Great Recession from December 2007 to June 2009 intensified debate about how much governments should intervene into the market economy. Conservatives and right-leaning political parties tend to champion free market capitalism and are critical of government intervention, maintaining it can lead to inefficiency and waste that hurts employment, wages, and economic growth. By contrast, left-leaning political parties and labor organizations argue for more intervention into the market to even out the ups and downs of the business cycle, Flavin said.

“We assessed respondents’ subjective well-being using a very straightforward question: ‘All things considered, how satisfied are you with your life as a whole these days?’” Flavin said. On a scale of 1 to 10 — with 10 the highest level of satisfaction — the average rating for all respondents for the duration of the survey was 7.48. The United States was ranked at No. 11 out of 21 countries on the list, with an average rating of 7.61.

Four measures of government policies were used by Flavin and co-researchers at the University of Notre Dame and Texas A&M University:

  • The overall size of government consumption as a percentage of national gross domestic product.
  • Social welfare expenditures as a percentage of the gross domestic product.
  • Welfare state generosity measured in terms of the ease of access to welfare benefits, the expansiveness of coverage to citizens of different statuses and life circumstances, and the degree to which social benefits replace incomes lost due to unemployment, retirement, or family circumstances.
  • Labor market regulations governing such circumstances as job dismissals, temporary employment, and mass layoffs.

The study’s findings held true regardless of whether respondents were rich or poor. The researchers also ruled out alternative explanations such as an individual’s health, education level, and marital status as well as the gross national product and unemployment rate of the country that he or she lives in.

“Are we saying we need a bigger government to be happier? No,” Flavin said. “Instead, our goal is to objectively examine the data and let people draw their own conclusions. If anything, this study is a conversation-starter about what role we envision for government in our lives and the advantages and disadvantages of government intervention into the market economy.”

Countries ranked from most to least satisfied – with 10 the highest level of satisfaction – included:

  • Denmark: 8.20
  • Switzerland: 8.10
  • Iceland: 8.04
  • Ireland: 7.95
  • Austria: 7.95
  • Finland: 7.82
  • Sweden: 7.82
  • Canada: 7.82
  • Norway: 7.78
  • Netherlands: 7.76
  • United States: 7.61
  • Australia: 7.58
  • Great Britain: 7.51
  • Belgium: 7.49
  • Germany: 7.08
  • Italy: 7.05
  • Portugal: 7.05
  • Spain: 6.96
  • France: 6.85
  • Greece: 6.67
  • Japan: 6.63
