Over the last few decades, economists and psychologists have quietly documented the many ways in which a person's IQ matters. But, research suggests that a nation's IQ matters so much more.As Garett ...Jones argues in Hive Mind, modest differences in national IQ can explain most cross-country inequalities. Whereas IQ scores do a moderately good job of predicting individual wages, information processing power, and brain size, a country's average score is a much stronger bellwether of its overall prosperity. Drawing on an expansive array of research from psychology, economics, management, and political science, Jones argues that intelligence and cognitive skill are significantly more important on a national level than on an individual one because they have "positive spillovers." On average, people who do better on standardized tests are more patient, more cooperative, and have better memories. As a result, these qualities—and others necessary to take on the complexity of a modern economy—become more prevalent in a society as national test scores rise. What's more, when we are surrounded by slightly more patient, informed, and cooperative neighbors we take on these qualities a bit more ourselves. In other words, the worker bees in every nation create a "hive mind" with a power all its own. Once the hive is established, each individual has only a tiny impact on his or her own life. Jones makes the case that, through better nutrition and schooling, we can raise IQ, thereby fostering higher savings rates, more productive teams, and more effective bureaucracies. After demonstrating how test scores that matter little for individuals can mean a world of difference for nations, the book leaves readers with policy- oriented conclusions and hopeful speculation: Whether we lift up the bottom through changing the nature of work, institutional improvements, or freer immigration, it is possible that this period of massive global inequality will be a short season by the standards of human history if we raise our global IQ.

Načrtovanje in izvedba anketne raziskave sta zelo kompleksna procesa. Spremljajo ju številni izzivi, ki pomembno vplivajo na uspešnost anketne raziskave. To velja tudi za samoanketiranje, kjer proces ...odgovarjanja poteka brez prisotnosti anketarja. Namen prispevka je osvetliti izbrane, doslej slabše raziskane metodološke vidike samoanketiranja: izbor načina anketiranja, stopnja sodelovanja, varovanje osebnih podatkov ter stroški in logistika. Rezultati temeljijo na primerjalni analizi štirih samoanketiranj z zelo velikimi vzorci, izvedenih med letoma 2012 in 2017. Na podlagi ugotovitev smo oblikovali nekaj metodoloških priporočil, ki so snovalcem in izvajalcem anketiranj lahko v pomoč pri načrtovanju in izvedbi raziskave.
Zusammenfassung Um auch die unbeabsichtigten Folgen ihrer Politik zu ermitteln, unternehmen Regierungen umfassende Gesetzesfolgenabschätzungen. Immer häufiger lassen sie sich dabei von unabhängigen ...Expertengremien kontrollieren. Doch: Wie erzielen diese Gremien Einfluss? Und welche Rolle spielen sie als Politikberater für Bürokratieabbau und bessere Rechtsetzung? Das Buch eröffnet neue Einblicke in die Entwicklungshistorie und Handlungsrealität der drei erfahrensten Normenkontrollräte in Europa. Vor dem Hintergrund unterschiedlicher Verwaltungskulturen werden die Ratstypen „Wachhund“, „Torwächter“ und „Kritischer Freund“ herausgearbeitet. Die Ergebnisse schärfen die politische und wissenschaftliche Debatte um die Leistungsfähigkeit von Normenkontrollräten. Abstract In order to calculate the unintended consequences of their policies, governments conduct comprehensive assessments of the impact of legislation. In doing so, they have independent expert committees monitor them on an increasingly frequent basis. However, in what ways do these committees have an influence in this respect? And what role do they play as policy advisors in terms of dismantling bureaucracy and better legislation? This book provides new insights into the history of the development of the three most experienced supervisory bodies in Europe and the reality of how they conduct themselves. Against the backdrop of various administrative cultures, the book presents the following types of supervisory committees in detail: ‘watchdog’, ‘gatekeeper’ and ‘critical friend’. Its findings intensify the political and academic debate on the performance and efficiency of supervisory bodies.
Telemonitoring improves clinical outcomes in patients with arterial hypertension (AH) and type 2 diabetes (T2D), however, cost structure analyses are lacking. This study seeks to explore the cost ...structure of telemonitoring for the elderly with AH and T2D in primary care and identify factors influencing costs for potential future expansions.
Infrastructure, operational, patient participation, and out-of-pocket costs were determined using a bottom-up approach. Infrastructure costs were determined by dividing equipment and telemonitoring platform expenses by the number of participants. Operational and patient participation costs were determined by considering patient training time, data measurement/review time, and teleconsultation time. The change in out-of-pocket costs was assessed in both groups using a structured questionnaire and 12-month expenditure data. Statistical analysis employed an unpaired sample t-test, Mann-Whitney U test, and chi-square test.
A total of 117 patients aged 71.4±4.7 years were included in the study. The telemonitoring intervention incurred an annual infrastructure costs of €489.4 and operational costs of €97.3 (95% CI 85.7-109.0) per patient. Patient annual participation costs were €215.6 (95% CI 190.9-241.1). Average annual out-of-pocket costs for both groups were €345 (95% CI 221-469). After 12 months the telemonitoring group reported significantly lower out-of-pocket costs (€132 vs. €545, p<0.001), driven by reduced spending on food, dietary supplements, medical equipment, and specialist check-ups compared to the standard care group.
To optimise the cost structure of telemonitoring, strategies like shortening the telemonitoring period, developing a national telemonitoring platform, using patient devices, integrating artificial intelligence into platforms, and involving nurse practitioners as telemedicine centre coordinators should be explored.
Abstract Introduction Arterial hypertension (AH) and type 2 diabetes (T2D) represent a significant burden for the public health system, with an exceptionally high prevalence in patients aged ≥65 ...years. This study aims to test the acceptability, clinical effectiveness, and cost-effectiveness of telemonitoring in elderly patients with AH and T2D at the primary care level. Methods A m ulti-centre, prospective, randomized, controlled t rial w ill be conducted. Patients a ged ≥ 65 y ears with AH and T2D will be randomized in a 1:1 proportion to a mHealth intervention or standard care group. Patients in the intervention group will measure their blood pressure (BP) twice weekly and blood glucose (BG) once monthly. The readings will be synchronously transmitted via a mobile application to the telemonitoring platform, where they will be reviewed by a general practitioner who will indicate changes in measurement regimen or carry out a teleconsultation. The primary endpoint will be a change in systolic BP (SBP) and glycated haemoglobin (HbA1c) relative to standard care up to 12 months after inclusion. Secondary endpoints will be a change in other observed clinical variables, quality-of-life indexes, and costs. Expected results Telemonitoring will be an acceptable method of care associated with significant reductions in SBP and HbA1c levels and an increase in quality-of-life indexes in the intervention group. However, the cost-effectiveness threshold (incremental cost-effectiveness ratio below €25,000/quality-adjusted life year) might not be reached. Conclusion This study will provide new evidence for scaling up telemonitoring network at the primary care level and modifying telemonitoring protocols to achieve the best clinical and cost-effective outcomes.
Migraine is associated with significant morbidity and a significantly negative impact on the quality of life. A better understanding of the economic impact of migraine is becoming increasingly ...important. This paper aims to shed light on absenteeism and presenteeism costs of migraine in Slovenia.
We use the administrative national-level database on sick leave due to migraine for 2016. The absenteeism cost estimate is based on the number of patients with migraine on physician-determined sick leave and average daily labour costs. We calculate productivity costs from a social perspective regardless of who incurs them. Data from the national registry on sick leave are coupled with data from a web-based self-reported survey to also include the cost of presenteeism. MIDAS and WPAI presenteeism items were used and several different scenarios were designed to assess presenteeism costs.
We estimated annual absenteeism costs per absentee due to migraine at the amount of EUR 531 in 2016 using the NIPH's administrative data on sick leave. Annual absenteeism costs per absentee due to migraine based on self-reported data amounted to EUR 626. The estimated annual presenteeism costs per patient range from EUR 344 - 900.
Estimating the economic burden of a disease is becoming increasingly important. This paper is an insight into the absenteeism and presenteeism costs of migraine in Slovenia.

Transaction costs of derivative hedging appear in financial markets. This paper considers the problem of delta hedging and the reduction of expected proportional transaction costs. In the literature ...the expected approximate proportional transaction costs are customarily estimated by the gamma term, usually the largest term of the associated series expansion. However, when options are to expire in a month or few weeks, other terms may become even larger so that more precise estimates are needed. In this paper, different higher-order estimates of proportional transaction costs are analyzed. The problem of the reduction of expected transaction costs is considered. As a result, a suitably adjusted delta is given, for which the expected approximate proportional transaction costs can be reduced. The order of the mean and the variance of the hedging error can be preserved. Several examples are provided.

Diabetes prevalence and costs are rising on aglobal scale. Therefore, it is necessary to periodically conduct cost studies for assessing the healthcare burden impact. In Slovenia, the last type 2 ...diabetes cost assessment was conducted in 2006, not including all diabetes complication costs. The aim of this study was to revise, update and compare to previously published datadirect healthcare costs of type 2 diabetes in Slovenia with additional complications costs consideration.
The study was performed from the healthcare payer perspective using the bottom-up approach, was prevalence based and estimated direct medical costs.
We estimated total yearly direct medical costs of type 2 diabetes in Slovenia to 99,120,419 euro with annual per capita costs of 834.70 euro. The highest cost shares were attributed to cardiovascular complication costs (21,683,919 euro), diabetes co-medication (20,977,269 euro) and diabetes treatment medication (18,505,015 euro). Highest yearly costs per complication (all cases, all occurrences) were estimated for dialysis I and III (9,162,635 euro), stroke first year costs (4,951,306 euro) and congestive heart failure first year costs (4,879,533 euro). Yearly per one patient, the complication costs were highest for kidney transplantation, followed by dialysis I and III (78,621.25 euro and 36,797.73 euro)
In comparison to the costs published in the literature before, our estimated total yearly direct medical costs were comparable, although annual per capita costs were assessed lower than elsewhere. Further, regarding the complication costs estimations, our assessed expenses were comparable to those published in other countries.
Prevalenca in stroški sladkorne bolezni v globalnem merilu naraščajo. Zato je treba redno izvajati študije stroškovnega bremena za oceno vpliva na zdravstvo. V Sloveniji je bila zadnja študija bremena sladkorne bolezni tipa 2 izvedena leta 2006 in ni upoštevala vseh stroškov diabetičnih zapletov. Cilj te raziskave je bil pregledati, posodobiti in primerjati s prej objavljenimi podatki neposredne medicinske stroške sladkorne bolezni tipa 2 v Sloveniji z upoštevanjem dodatnih diabetičnih zapletov.
Študija je bila izvedena z vidika plačnika zdravstvenega varstva; uporabljen je bil pristop »bottom-up« s prevalenčnim vidikom in ocenjeni so bili neposredni medicinski stroški.
Letne neposredne medicinske stroške sladkorne bolezni tipa 2 smo ocenili na 99,120.419 evrov z 834,70 evra letnih stroškov na osebo. Najvišji delež je pripadal stroškom srčno-žilnih zapletov (21,683.919 evrov), stroškom sočasno uporabljenih zdravil (20,977.269 evrov) in stroškom antidiabetikov in inzulinov (18,505.015 evrov). Najvišji letni stroški za diabetični zaplet (vse ponovitve in vsi primeri) so bili ocenjeni za dializo I in III (9,162.635 evrov), prvo leto možganske kapi (4.951.306 evrov) in prvo leto srčnega popuščanja (4,879.533 evrov). Najdražji zaplet sladkorne bolezni (letno na posameznega bolnika) je bila transplantacija ledvic (78.621,25 evra), sledili sta dializa I in III (letno na osebo 36.797,73 evra).
V primerjavi s prej objavljenimi podatki v literaturi so v tej raziskavi objavljeni letni neposredni medicinski stroški primerljivi, čeprav so letni stroški na osebo ocenjeni nižje kot drugje. Prav tako so stroškovne ocene posameznih zapletov sladkorne bolezni primerljive s prej objavljenimi.
