Within a field experiment, I present a treatment group with reductions in information, administrative, stigma, and procrastination costs associated with the Advance EITC. The treatment increases Advance participation from 0.3 to 1.2 percent. Another treatment simultaneously encourages 401(k) savings, increasing 401(k) participation from 46 to 50 percent. However, there is no additional increase in Advance participation when coupled with the 401(k) treatment, casting doubt on a long-term forced savings motive. The results indicate that EITC recipients actively forgo the Advance. Further work is needed to identify what underlies these preferences. Possible explanations include uncertainty and/or short-term forced savings motives. (JEL D14, D82, H23, H24, H31)

Background and Objective: There may be a possible link between the use of HAART and oxidative stress-related mitochondrial dysfunction in HIV patients. We evaluated the mitochondrial and oxidative impacts of short and long-term administration of HAART on HIV patients attending the Enugu State University Teaching (ESUT) Hospital, Enugu, Nigeria following short and long-term therapy. Methods: 96 patients categorized into four groups of 24 individuals were recruited for the study. Group 1 comprised of age-matched, apparently healthy, sero-negative individuals (the No HIV group); group 2 consisted of HIV sero-positive individuals who had not started any form of treatment (the Treatment naïve group). Individuals in group 3 were known HIV patients on HAART for less than one year (Short-term treatment group), while group 4 comprised of HIV patients on HAART for more than one year (Long-term treatment group). All patients were aged between 18 to 60 years and attended the HIV clinic at the time of the study. Determination of total antioxidant status (TAS in nmol/l), malondialdehyde (MDA in mmol/l), CD4+ count in cells/μl, and genomic studies were all done using standard operative procedures. Results: We found that the long-term treatment group had significantly raised the levels of MDA, as well as significantly diminished TAS compared to the Short-term treatment and No HIV groups (P<0.05). In addition, there was significantly elevated variation in the copy number of mitochondrial genes (mtDNA: D-loop, ATPase 8, TRNALEU uur) in the long-term treatment group. Interpretation and Conclusion: Long-term treatment with HAART increases oxidative stress and causes mitochondrial alterations in HIV patients.

Additional Labor

A field experiment in Sri Lanka provided wage subsidies to randomly chosen microenterprises to test whether hiring additional labor benefits such firms and whether a short-term subsidy can have a lasting impact on firm employment. Using 12 rounds of surveys to track dynamics 4 years after treatment, we find that firms increased employment during the subsidy period. Treated firms were more likely to survive, but there was no lasting impact on employment and no effect on profitability or sales either during or after the subsidy period. There is some heterogeneity in effects; the subsidies have a more durable effect on manufacturers. (JEL C93, J22, J24, J31, J38, O14, O15)

This study provides a theoretical framework and experimental evidence on how managers' disclosure decisions affect their credibility with investors. I find that in the short-term, more forthcoming disclosure has a positive effect on management's reporting credibility, especially when management is forthcoming about negative news. However, these short-term credibility effects do not persist over time. In the long-term, managers who report positive earnings news are rated as having higher reporting credibility than managers who report negative earnings news, regardless of their previous disclosure decisions.

Negative Signal

The stigma associated with long-term unemployment spells could create large inefficiencies in labor markets. While the existing literature points toward large stigma effects, it has proven difficult to estimate causal relationships. Using data from a field experiment, we find that long-term unemployment spells in the past do not matter for employers' hiring decisions, suggesting that subsequent work experience eliminates this negative signal. Nor do employers treat contemporary short-term unemployment spells differently, suggesting that they understand that worker/firm matching takes time. However, employers attach a negative value to contemporary unemployment spells lasting at least nine months, providing evidence of stigma effects. (JEL E24, J23, J64, J71)

Neonicotinoides are persistent and highly toxic pesticides that have become popular instead of organophosphates, being suspected to be a trigger of massive disappearance of bees that raises concern in the world. The evaluation of the long-term influence for a whole colony in the natural environment is, however, not established yet. In this paper, we conducted a long-term field experiment and found different impacts on honeybee colonies (Apis mellifera) in an apiary between the neonicotinoid dinotefuran and the organophosphate fenitrothion even though whose concentrations in sugar syrup provided for bees were adjusted to have nearly equal short-term effects on a honeybee based on the median lethal dose (LD50) as well as the insecticidal activity to exterminate stinkbugs. The colony with administration of dinotefran (dinotefuran colony) became extinct in 26 days, while the colony with administration of fenitrothion (fenitrothion colony) survived the administration for the same period. Furthermore, the fenitrothion colony succeeded to be alive for more than 293 days after administration, and also succeeded an overwintering, which indicates that colonies exposed to fenitrothion can recover after the exposure. Meanwhile, the dinotefuran colony became extinct even though the intake of dinotefuran was estimated to be comparable with that of fenitrothion in terms of the LD50 of a honeybee. Moreover, the colonies in our previous long-term experiments where dinotefuran with higher concentration were administered only for first few days (Yamada et al., 2012) became extinct in 104 days and 162 days, respectively. From these results, we speculate that colonies exposed to dinotefuran hardly recover from the damage because dinotefuran is much more persistent than fenitrothion and toxic foods stored in cells can affect a colony in a long period.

The behavior of Griesgletscher, Switzerland, is studied by application of a numerical model of temperate glacier flow. The analysis addresses the possible danger posed to a hydroelectric dam which is 600 m from the calving terminus of the glacier. Model parameters are adjusted to fit data collected over eleven years. A calving law relating the calving flux to the water depth at the front provides a good fit of the data. Assuming a continuation of the present climate, the terminus is predicted to retreat 200 m over the next forty years, followed by an advance of 150 m lasting several centuries. Numerous experimental climate alterations show that the dam will not be threatened by short-term climatic changes. A long-term mass-balance increase of 0.12 m of ice per year (or a drop of 0.2°C in mean annual air temperature) would be sufficient to fill the reservoir with ice. With an additional increase of 0.07 m of ice per year the terminus would reach the dam. Data from the 1923 and 1850 moraines are used to suggest lower-bound estimates of temperature changes (-0.4 and -0.6°C respectively) during these periods of glacial maxima.

Research has found that, for long-term dating, women value men with greater financial resources and higher status, while for short-term dating they value men with greater physical attractiveness. However, there are discrepant results for both long- and short-term dating. As most of the previous studies used only questionnaires, we conducted a field experiment to evaluate women’s receptivity to men’s date requests. Young male confederates who ostensibly had high, middle, or low incomes, depending on the experimental condition, asked young women walking down the street for their phone number. We found that men’s financial resources were positively associated with compliance with their request. Evolutionary theory proposing that women select men with greater resources for them and their offspring is used to explain the results.

Objective.To observe the clinical efficacy of the Chinese herb, Triptolide, in children with moderately severe Henoch-Schönlein purpura nephritis (HSPN).Methods. From January 2007 to December 2011, 56 HSPN children manifested by nephrotic range proteinuria with normal kidney function and<50% crescents or sclerosing lesions on biopsy were hospitalized in the Children’s Hospital of Zhejiang University School of Medicine. They were divided into two groups: the treatment group (Triptolide at a dosage of 1 mg/kg·d, combined with prednisone at a dosage of 2 mg/kg·d, within a course of medium-to-long-term therapy of 6 to 9 months) and the control group (; prednisone alone, with the same procedure).Results.Short-term remission was observed in 95% of patients from treatment group and in 72% of patients from control group, respectively. There was a significant difference between both groups () for short-term effects. Meanwhile, no significant difference, as proteinuria, hematuria, hypertension, and decreased eGFR, was observed between the two groups in long-term followup (). The Kaplan-Meier plot analysis also revealed no significant difference ().Conclusion.Triptolide is effective in relieving short-term symptoms for moderately severe HSPN children, though its long-term effects need to be observed further.
