Is Leisure a Normal Good? Evidence from the European Parliament

Prior to July 2009, salaries of the members of the European Parliament were paid by their home country and there were substantial salary differences between parliamentarians representing different EU countries. Starting in July 2009, the salary of each member of the Parliament is pegged to 38.5% of a European Court judge’s salary, paid by the EU. This created an exogenous change in salaries, the magnitude and direction of which varied substantially between parliamentarians. Parliamentarians receive per diem compensation for each plenary session they attend, but salaries constitute unearned income as they are independent of attendance to the Parliament. Using detailed information on each parliamentarian of the European Parliament between 2004 and 2011 we show that an increase in salaries reduces attendance to plenary sessions and an increase in per diem compensation increases it. We also show that corruption in home country has a negative effect on attendance for seasoned members of the Parliament.

Theft and Deterrence

We report results from economic experiments of decisions that are best described as petty larceny, with high school and college students who can anonymously steal real money from each other. Our design allows exogenous variation in the rewards of crime, and the penalty and probability of detection. We find that the probability of stealing is increasing in the amount of money that can be stolen, and that it is decreasing in the probability of getting caught and in the penalty for getting caught. Furthermore, the impact of the certainty of getting caught is larger when the penalty is bigger, and the impact of the penalty is bigger when the probability of getting caught is larger.crime, punishment, incentives, deterrence, juvenile, arrest, risk, larceny

An Experimental Test of Criminal Behavior Among Juveniles and Young Adults

We report results from economic experiments that provide a direct test of the hypothesis that criminal behavior responds rationally to changes in the possible rewards and in the probability and severity of punishment. The experiments involve decisions that are best described as petty larceny, and are done using high school and college students who can anonymously take real money from each other. We find that decisions about whether and how much to steal are, in general, rational and responsive to the variations in tradeoffs, and sometimes, though not always, to the overall availability of criminal opportunities.

The role of ultraviolet radiation and tyrosine stimulated melanogenesis in the induction of oxidative stress alterations in fair skin melanocytes

Melanocytes are producing melanin after UV irradiation as a defense mechanism. However, UV-induced damage is involved in melanoma initiation, depending on skin phototype. Melanocytes seem to be extremely susceptible to free radicals. Their main enzymatic antioxidants are superoxide dismutase and catalase. Aim: To study how melanin synthesis modulates the activity of the oxidative stress defense enzymes and cell proliferation after UV induced cell damage. Methods: Normal human melanocyte cultures from fair skin individuals were exposed to high levels of L-tyrosine and irradiated, with 20, 30, 40 mJ/cm2 UVA, and respective UVB. Proliferation was measured using a MTS assay; viability was assessed by trypan blue exclusion dye method. Spectrophotometrical methods were used to determine total melanin content, the enzymatic activity of tyrosinase, superoxide dismutase and catalase. Results: Tyrosine had a negative effect on proliferation, enhanced with time elapsed. Overall, UV irradiation decreased proliferation. UVA increased proliferation relative to UVB in the cultures exposed for a longer time to high (2 mM) tyrosine concentration. There were no proliferation differences between UVA and UVB irradiation in lower tyrosine concentration exposed melanocytes. Both, UV irradiation and tyrosine increased melanogenesis. Exposure of the melanocytes to increased levels of tyrosine in medium (0.5 mM and 1 mM) and UV irradiation enhanced the activity of superoxide dismutase and catalase. The enzymes showed a high activity rate in melanocytes while exposed for a short time to 2 mM tyrosine, but their activity was dramatically decreased with longer tyrosine exposure and UV irradiation. Conclusion: Our data indicate that in low phototype melanocytes, melanogenesis, either following UV irradiation, or tyrosine exposure, especially in high concentrations, was detrimental for the cells by reducing the activity of catalase and superoxidedismutase, the natural antioxidants. UVA was more efficient in stimulating the activity of superoxide dismutase and catalase but also in depleting the reserves of the enzymatic defense against oxidative stress, especially catalase, than UVB. This physiologic response to UV light can be considered as an adjunctive risk factor for people with low phototype for developing a melanoma, when exposed to UV irradiation

Deterrence and Compellence in Parliament

In most countries, parliamentary immunity protects lawmakers from civil or criminal charges while in office, and it shields them from prosecution for their political speech and actions. We present the first empirical analysis of the impact of parliamentary immunity on the behavior and performance of politicians. Leveraging a constitutional amendment that lifted the immunity of 24 percent of the members of the Turkish Parliament (MPs), we find that losing immunity from prosecution pacifies opposition MPs, who become less diligent (drafting and initiating fewer pieces of legislation or inquiries, delivering fewer and shorter speeches) and less aggressive (interrupting other MPs less frequently). Their tendency to cast dissenting votes against the government is also reduced. These MPs are less likely to be renominated by their parties for the next election, and they are less likely to be reelected. The loss of immunity has no impact on government-aligned MPs

Intended and Unintended Consequences of Prison Reform

Since the 1970s, U.S. federal courts have issued court orders condemning state prison crowding. However, the impact of these court orders on prison spending and prison conditions is theoretically ambiguous because it is unclear if these court orders are enforceable. We examine states' responses to court interventions and show that these interventions generate higher per inmate incarceration costs, lower inmate mortality rates, and a reduction in prisoners per capita. If states seek to minimize the cost of crime through deterrence, an increase in prison costs should lead states to shift resources from corrections to other means of deterring crime such as welfare and education spending. However, we find that court interventions, that are associated with higher corrections expenditures, lead to lower welfare expenditures. This suggests that the burden of increased correctional spending is borne by the poor. Furthermore, states do not increase welfare spending after their release from court order; making the reduction in welfare spending permanent. Thus, our results suggest that states do not respond to prison reform in the manner prescribed by the deterrence model. States' responses to prison reform are most consistent with the predictions in the empirical public finance literature that indicate stickiness in expenditure categories and that increases in spending in programs that affect the poor generate declines in expenditures in other program that are also targeted to the poor.

Nano-Antimicrobial Solutions Using Synthetic-Natural Hybrid Designs

Nanotechnology potential in antimicrobial therapy is increasingly demonstrated by various data. Results reveal antibacterial properties, comparable to that of conventional antibiotics. Working on parallel experiments, researchers continue to bring evidence demonstrating age-old-recognized antibacterial properties of various natural components of plant and animal origin. Later years brought an increasing trend for combining synthetic and natural composition in new constructs. The tendency aims to bring more on different essential aspects, such as active substance release, improvement of antibacterial effect, and up-regulation of the mechanisms at the structure-cell interface. Present chapter structures the up-to-date achievements in the field, including the concept of design, biological effects, benefits, mechanisms, and limitations of the field. Also, expected future research directions are to be discussed
