Ambiguity and Insurance

Why don’t people in developing countries insure themselves? I propose that some households are ambiguity averse, and that these households fear any insurance contract they purchase will payout when it is not needed and will not payout when it is. I study two applications of this observation. I first study formal crop insurance, in particular index insurance and the insurance element of limited liability credit. I provide a formal model of ambiguity aversion and derive four implications. First, households that are sufficiently ambiguity averse will not value any actuarially fair insurance contract and will have a lower willingness to pay for any specific contract. Second, because learning diminishes the impact of ambiguity, increased experience with the insured crop will mitigate the effect of ambiguity aversion. Third, increasing risk aversion makes index insurance more valuable for the ambiguity neutral, and relatively less valuable for the ambiguity averse. Fourth, increasing risk aversion has no effect on the demand for limited liability credit (ie, a state contingent transfer) for ambiguity neutral individuals, but increases demand for limited liability credit for the ambiguity averse. I test these predictions using two experiments, one on rainfall insurance in Malawi and one on limited liability credit in Kenya. Both data sets contain baseline measures of ambiguity aversion and risk aversion, and strongly support the theoretical claims. As a second application I study informal risk sharing. I provide a model showing that the same preferences used to study crop insurance can explain the common finding that consumption is sensitive to idiosyncratic income shocks. The model I use assumes that households cannot make accurate probability assessments and entertain a set of priors. I assume these households assess uncertain prospects using a prior that minimizes the gain from leaving the endowment. The model implies that households have different beliefs at the optimal contract, creating a wedge between the consumption levels of households giving and receiving transfers in any state. I derive testable implications from the model, which I evaluate using both the ICRISAT village level data from India and the Townsend Thai monthly panel. I am unable to reject the model using either data set. 1 Ambiguity Aversion and Missing Insurance Markets
Anisotropic Triebel-Lizorkin Spaces with Doubling Measures

We introduce and study anisotropic Triebel-Lizorkin spaces associated with general expansive dilations and doubling measures on Rn with the use of wavelet transforms. This work generalizes the isotropic methods of dyadic φ-transforms of Frazier and Jawerth to nonisotropic settings. We extend results involving boundedness of wavelet transforms, almost diagonality, smooth atomic and molecular decompositions to the setting of doubling measures. We also develop localization techniques in the endpoint case of p = ∞, where the usual definition of Triebel-Lizorkin spaces is replaced by its localized version. Finally, we establish nonsmooth atomic decompositions in the range of 0 < p ≤ 1, which is analogous to the usual Hardy space atomic decompositions.
Validation and patient acceptance of a computer touch screen version of the WOMAC 3.1 osteoarthritis index.

OBJECTIVES
To validate the WOMAC 3.1 in a touch screen computer format, which applies each question as a cartoon in writing and in speech (QUALITOUCH method), and to assess patient acceptance of the computer touch screen version.


METHODS
The paper and computer formats of WOMAC 3.1 were applied in random order to 53 subjects with hip or knee osteoarthritis. The mean age of the subjects was 64 years (range 45 to 83), 60% were male, 53% were 65 years or older, and 53% used computers at home or at work. Agreement between formats was assessed by intraclass correlation coefficients (ICCs). Preferences were assessed with a supplementary questionnaire.


RESULTS
ICCs between formats were 0.92 (95% confidence interval, 0.87 to 0.96) for pain; 0.94 (0.90 to 0.97) for stiffness, and 0.96 (0.94 to 0.98) for function. ICCs were similar in men and women, in subjects with or without previous computer experience, and in subjects below or above age 65. The computer format was found easier to use by 26% of the subjects, the paper format by 8%, and 66% were undecided. Overall, 53% of subjects preferred the computer format, while 9% preferred the paper format, and 38% were undecided.


CONCLUSION
The computer format of the WOMAC 3.1 is a reliable assessment tool. Agreement between computer and paper formats was independent of computer experience, age, or sex. Thus the computer format may help improve patient follow up by meeting patients' preferences and providing immediate results.
Determination of standard zinc values in the intact tissues of mice by ICP spectrometry

The most commonly encountered difficulties for the quantitative measurement of zinc in biological samples are the limited sample amount, total and effective digestion of connective and fatty residues, and low zinc concentrations. These problems often lead to the determination of lower zinc values than actually present, so that the sample preparation, digestion, and analytical procedure deserve careful attention. In this short communication, a new method for microwave tissue disintegration is described. The authors have obtained consistent and reproducible results with tissue samples of 0.5 g or less.
Association between myocardial substrate, implantable cardioverter defibrillator shocks and mortality in MADIT-CRT.

OBJECTIVE
The aim of the present study was to assess a possible association between myocardial substrate, implantable cardioverter defibrillator (ICD) shocks, and subsequent mortality.


METHODS
Within the multicentre automatic defibrillator implantation trial-cardiac resynchronization therapy (MADIT-CRT) population (n = 1790), we investigated the association between myocardial substrate, ICD shocks and subsequent mortality using multivariate Cox regression analyses and landmark analyses at 1-year follow-up.


RESULTS
The 4-year cumulative probability of ICD shocks was 13% for appropriate shock and 6% for inappropriate shock. Compared with patients who never received ICD therapy, patients who received appropriate shock had an increased risk of mortality [HR = 2.3 (1.47-3.54), P < 0.001], which remained increased after adjusting for echocardiographic remodelling at 1 year (HR = 2.8, P = 0.001). Appropriate anti-tachycardia pacing (ATP) only was not associated with increased mortality (P = 0.42). We were not able to show an association between inappropriate shocks (P = 0.53), or inappropriate ATP (P = 0.10) and increased mortality. Advanced myocardial structural disease, i.e. higher baseline echocardiographic volumes and lack of remodelling at 1 year, was present in patients who received appropriate shocks but not in patients who received inappropriate shocks or no shocks.


CONCLUSION
In the MADIT-CRT study, receiving appropriate ICD shocks was associated with an increased risk of subsequent mortality. This association was not evident for appropriate ATP only. These findings, along with advanced cardiac structural disease in the patients who received appropriate shocks, suggest that the compromised myocardium is a contributing factor to the increased mortality associated with appropriate ICD shock therapy.

Low contact force and force–time integral predict early recovery and dormant conduction revealed by adenosine after pulmonary vein isolation

AIM
After pulmonary vein isolation (PVI), dormant conduction (DC) is present in at least one vein in a substantial number of patients. The present study seeks to determine whether there is a relationship between poor contact forces (CF) and the presence of DC after PVI.


METHODS AND RESULTS
This prospective, operator-blinded, non-randomized dual-centre trial enrolled 34 consecutive patients with paroxysmal atrial fibrillation who were candidates for PVI. Radiofrequency (RF) energy was delivered by using an irrigated-tip force-sensing ablation catheter (Tacticath, St Jude Medical) at pre-defined target power. The operators were blinded to the CF data at all times. A total of 1476 RF applications were delivered in 743 pre-defined PV segments. For each application, the precise location of the catheter was registered and the following data were extracted from the Tacisys unit: application duration, minimum contact force, maximum contact force, average contact force (CF), and force-time integral (FTI). Sixty minutes after PVI, spontaneous early recovery (ER) of the left atrium (LA) to PV conduction was evaluated. In the absence of ER, the presence of a DC was evaluated by using intravenous adenosine (ATP). In the 34 patients recruited (23 males; mean age: 62 ± 9 years), all PVs were successfully isolated. At the end of the 60 min waiting period, 22 patients demonstrated at least one spontaneous ER or DC under ATP. The mean CF and FTI per PV segment differed significantly among the different veins but the sites of ER and DC were evenly distributed. However, both the minimum, the first and the mean CF and FTI per PV segment were significantly lower in the PV segments presenting either ER or DC as compared with those without ER or DC (mean CF: 4.9 ± 4.8 vs. 12.2 ± 1.65 g and mean FTI: 297 ± 291 vs. 860 ± 81 g s, P < 0.001 for both). Using multivariate analysis, both the mean CF and the FTI per lesion remained significantly associated with the risk of ER or DC. Moreover, a CF < 5 g per PV segment predicted ER+ and DC+ with a sensitivity of 71% and specificity of 82%. In contrast, ER and DC were very unlikely if RF application was performed with a mean CF > 10 g (negative predictive value: 98.7%).


CONCLUSION
Both a low CF and a low FTI are associated with the ER of the PVI and DC after PVI.
Geo-Bibliometric Mapping of French Geography: An Examination of Geography Dissertations Produced in France.

Abstract French geography dissertations for the years 1985–2002 were examined for their salient characteristics in terms of degree production, dissertation type, institutional affiliation, and geographical reach. These dissertations offer a rich base of research conducted in a country known for its innovative geographical research and tradition. Particular strengths and trends were discerned and concentrations of institutional base and activity established. This study can serve as a template for other national research traditions and disciplines, and is especially useful for library science and those interested in characteristics of literature studies.
Influence of Glutathione Oxidation and pH on Thermal Formation of Maillard-Type Volatile Compounds

The Maillard-type volatile compounds obtained from the reaction of glutathione and glucose were mainly furans, carbonyl compounds, and sulfur-containing compounds including thiophenes, thiazoles, and cyclic polysulfides. Both pH 8.0 and 6.0 were favorable conditions for sulfur-containing compound formation, whereas acidic conditions were favorable for furan and derivative formation. The reaction between glutathionesulfonic acid, an oxidized form of glutathione, and glucose primarily produced furans, carbonyl compounds, pyrazines, and pyrroles. Furans dominated the products obtained from the reactions at pH 6.0 and 8.0. Pyrazines increased as the reaction pH increased. The disappearance of sulfur-containing compounds in the products of glutathionesulfonic acid and glucose reaction systems indicated glutathionesulfonic acid could not provide hydrogen sulfide for the reaction. Keywords: Glutathione; glutathionesulfonic acid; sulfur-containing; oxidation; pH
Motivating IS security compliance: Insights from Habit and Protection Motivation Theory

Employees’ failure to comply with IS security procedures is a key concern for organizations today. A number of socio-cognitive theories have been used to explain this. However, prior studies have not examined the influence of past and automatic behavior on employee decisions to comply. This is an important omission because past behavior has been assumed to strongly affect decision-making. To address this gap, we integrated habit (a routinized form of past behavior) with Protection Motivation Theory (PMT), to explain compliance. An empirical test showed that habitual IS security compliance strongly reinforced the cognitive processes theorized by PMT, as well as employee intention for future compliance. We also found that nearly all components of PMT significantly impacted employee intention to comply with IS security policies. Together, these results highlighted the importance of addressing employees’ past and automatic behavior in order to improve compliance. 2012 Elsevier B.V. All rights reserved. * Corresponding author.

[HP-FSH (Fostimon)--a matter of choice in women with low ovarian response].

UNLABELLED
Assisted reproductive technologies (ART) are one of the most dynamic fields of the medical science. ART beginning on 25th of July 1978 with the pioneering scientific work of P. Steptoe and B. Edwards. Although the ART have improved dramatically since 1978, the success of that treatment remains unsatisfactory. More than 25 years experience in IVF accrued in believe that a break-through in success rates can soon be reach. The guarantee of IVF success remains the good ovarian response, which very often is a challenge for reproductive specialist. The manuscript is a review of the literature about the most successful therapy for controlled ovarian stimulation for IVF in aged infertile women and/or low ovarian responders.


CONCLUSIONS
The ovarian stimulation with highly purified gonadotrophins (HP-FSH) in outlined group of patient is associated with fewer oocytes retrieval, but higher proportion of top-quality embryos compared with rFSH, an improved capacity to implant, ongoing pregnancy and live birth rate among the top-quality embryos, derived from stimulation with HP-hMG compared with top-quality embryos in the rFSH group. High purified hMG better performed than rFSH in older women and women with poor ovarian response, probably of exogenous LH activity and/or relatively higher acidic isoforms of the FSH protein (produced when lower estrogen levels are present) which may be of relevance for clinical outcome.
A phase I study of full-dose gemcitabine and regional arterial infusion of nafamostat mesilate for advanced pancreatic cancer.

BACKGROUND
The primary end points of this study were to determine the dose-limiting toxic effects (DLTs), maximum tolerated dose, and a recommended phase II dose of a synthetic serine protease inhibitor, nafamostat mesilate, in combination with full-dose gemcitabine in patients with unresectable locally advanced or metastatic pancreatic cancer. The secondary end point was to assess therapeutic response.


PATIENTS AND METHODS
Patients with previously untreated pancreatic cancer received gemcitabine (1 000 mg/m(2) i.v. for 30 min) on days 1, 8, and 15, with nafamostat mesilate (continuous regional arterial infusion for 24 h through a port-catheter system) on days 1, 8, and 15; this regimen was repeated at 28-day intervals. The initial dose of nafamostat mesilate was 2.4 mg/kg and was escalated in increments of 1.2 mg/kg until a dose of 4.8 mg/kg was achieved. A standard '3+3' phase I dose-escalation design was used. Therapeutic response and clinical benefit response were assessed.


RESULTS
Twelve patients were enrolled in this study. None of the patients experienced DLTs, and nafamostat mesilate was well tolerated at doses up to 4.8 mg/kg in combination with full-dose gemcitabine. This combination chemotherapy yielded a reduction of a high serum level of the tumor marker CA19-9. Pain was reduced in three of seven patients without oral morphine sulfate. Overall survival was 7.1 months for all patients.


CONCLUSION
This phase I study was carried out safely. This combination chemotherapy showed beneficial improvement in health-related quality of life. The recommended phase II dose of nafamostat mesilate in combination with full-dose gemcitabine is 4.8 mg/kg.
Educational Status of Tribals of Jammu & Kashmir: A Case of Gujjars and Bakarwals

Education as a means of advancement of capacity, well –being and opportunity is uncontested and more so among communities on the periphery. In India, marked improvements in access and to some extent in quality of education in tribal areas have occurred and stem from various government and non-government initiatives. However, the number of out-of-school children continues to be several millions mainly due to lack of proper infrastructure, teacher absenteeism and attitude, parental poverty, seasonal migration, lack of interest and parental motivation etc. The scenario of tribal education is no way different than other states in Jammu and Kashmir. In Jammu & Kashmir the overall literacy rate of the Scheduled tribes as per the census 2001 is 3.7percent which is much lower than the national average of 47.1percent aggregated for all S.Ts. Though various efforts have been made by the government for the development of education among tribal communities but much more still needs to do. In this paper an attempt has been made to explore the existing educational status of two prominent tribal communities of Jammu and KashmirGujjars and Bakarwals. The study has been conducted in five tribal villages of district Anantnag. 124 households were selected with the help of stratified sampling for the survey. The study apart from presenting the existing educational status of Gujjars and Bakarwals in the area also provides suitable recommendations for the development of education among these tribal communities.
Combining clinical microsystems and an experiential quality improvement curriculum to improve residency education in internal medicine.

Beth Israel Deaconess Medical Center's internal medicine residency program was admitted to the new Education Innovation Project accreditation pathway of the Accreditation Council of Graduate Medical Education to begin in July 2006. The authors restructured the inpatient medical service to create clinical microsystems in which residents practice throughout residency. Program leadership then mandated an active curriculum in quality improvement based in those microsystems. To provide the experience to every graduating resident, a core faculty in patient safety was trained in the basics of quality improvement. The authors hypothesized that such changes would increase the number of residents participating in quality improvement projects, improve house officer engagement in quality improvement work, enhance the culture of safety the residents perceive in their training environment, improve work flow on the general medicine ward rotations, and improve the overall educational experience for the residents on ward rotations.The authors describe the first 18 months of the intervention (July 2006 to January 2008). The authors assessed attitudes and the educational experience with surveys and evaluation forms. After the intervention, the authors documented residents' participation in projects that overlapped with hospital priorities. More residents reported roles in designing and implementing quality improvement changes. Residents also noted greater satisfaction with the quality of care they deliver. Fewer residents agreed or strongly agreed that the new admitting system interfered with communication. Ongoing residency program assessment showed an improved perception of workload, and educational ratings of rotations improved. The changes required few resources and can be transported to other settings.
The effect of solute concentration on fluidity and structure in aqueous solutions of electrolytes—V. Strong acids and alkali-metal hydroxides

Abstract An examination has been made of the effect of concentration on the temperature dependence of fluidity in aqueous solutions of the strong acids HCl, HBr, HNO 3 , HClO 3 , H 2 SO 4 and H 3 PO 4 , and the alkali-metal hydroxides LiOH, NaOH and KOH. The results suggest that, because of ion association and complex hydration effects in the other systems, only HCl and KOH are capable of giving the least equivocal information about the behaviour of H + and OH − in fluid motion. It is also concluded that both H + and OH − are positively hydrated structure-brea entities, and that despite their special properties their effect on fluidity is not materially different from other positively hydrated structure-break ions.
Individualized medication assessment and planning: optimizing medication use in older adults in the primary care setting.

STUDY OBJECTIVE
To test the feasibility and effectiveness of an individualized Medication Assessment and Planning (iMAP) program integrated within a primary care practice on the number and prevalence of medication-related problems (MRPs) and acute health services utilization, defined as combined hospitalizations and emergency department visits.


DESIGN
Six-month, prospective, observational pilot study.


SETTING
Community-based primary care medical practice.


PATIENTS
Convenience sample of 64 patients aged 65 years and older who were taking at least five medications.


INTERVENTION
Each patient was enrolled in the iMAP program-a collaborative, multifaceted intervention facilitated by a clinical pharmacist whereby patients receive comprehensive medication therapy management at baseline and 3 and 6 months as part of routine clinical care.


MEASUREMENTS AND MAIN RESULTS
MRPs were assessed and recommendations proposed using the previously published MRP classification tool; physician acceptance of recommendations served to validate the assessments. There was a significant reduction in mean number of MRPs/patient (4.2 at baseline vs 1.0 at 6 mo, p<0.0001) when adjusted for number of medications, race, and pharmacist. The prevalence of MRPs at 6 months compared with baseline was also significant (p<0.0008). Acute health services utilization was assessed by medical record abstraction. The 64 patients experienced a rate of 8.3 events/100 person-months (64 total events) during the 12-month prestudy period. During the 6-month study period, the same patients experienced 5.4 events/100 person-months (20 total events). Thus, we noted a reduction in acute health services utilization of 35%. Physicians were enthusiastically supportive of iMAP.


CONCLUSION
iMAP has the potential to address a significant and timely issue affecting older adults and primary care practices: the burden of managing and continuously monitoring multiple medications in medically complex older adults. A more rigorous evaluation of iMAP is warranted and planned to demonstrate sustained effectiveness and cost-benefit.
Progressive Estate Taxation

For an economy with altruistic parents facing productivity shocks, the optimal estate taxation is progressive: fortunate parents should face lower net returns on their inheritances. This progressivity reflects optimal mean reversion in consumption, which ensures that a long-run steady state exists with bounded inequality - avoiding immiseration.
