    We design an experiment to study how reversible entry decisions are affected by public and private payoff disclosure policies. In our environment, subjects choose between a risky payoff, which evolves according to an autoregressive process, and a constant payoff. The treatments vary the information disclosure rule on the risky payoff, such that in the public information treatment the risky payoff is always observable, while in the private information treatment, the risky payoff is observable only to the participants who enter the market. We find that under private information, market entry is higher, which suggests that subjects engage in exploration and place value on information.publishedVersio

    La modernización de las entidades públicas y la creciente necesidad de mantener un clima laboral agradable es una temática importante en la actualidad, porque atribuye impacto directo en la percepción que el colaborador tiene con respecto a las prácticas administrativas, procesos, tecnología y otros factores, repercutiendo en su desempeño y por ende en el resultado de las organizaciones. Este trabajo tiene como propósito aplicar un modelo de evaluación que determine los factores que inciden en el clima laboral del GAD Provincial de Chimborazo, utilizando técnicas de recopilación de información, tales como entrevistas, observación y encuestas aplicadas a una muestra de 172 trabajadores. La investigación tiene un enfoque cuantitativo, diseño no experimental transversal y un alcance descriptivo – correlacional. Los resultados, al aplicar una combinación del Modelo de Litwin y Stringer (1968) & Williams (2013), reflejaron que el clima laboral del GADPCH fue del 44%.  De acuerdo a cada dimensión, los siguientes: Estructura (67%), Conflicto (41%), Identidad (53%), Cooperación / Apoyo (42%), Recompensas (29%) y Comunicación (34%), resultando en un clima laboral regular.  Es evidente la existencia de un cierto nivel de insatisfacción de los servidores públicos con respecto a su entorno laboral. Se presenta una propuesta, que contiene el planteamiento de estrategias de solución aplicadas a las dimensiones que obtuvieron la valoración más baja, mismas que están enfocadas a elevar la motivación, implementar nuevas técnicas de comunicación internas, gestionar arreglos satisfactorios por causa de un conflicto y también para fomentar el espíritu de trabajo en equipo

    The Impact of ETF Index Inclusion on Stock Prices

    We report on a laboratory experiment examining how demand for ETF index products affects the prices and trading volume of assets. We compare an environment where the ETF index includes all assets in a market against an environment where a redundant asset is excluded from the index. We find that (i) subjects place significant value on the ETF index asset beyond the value of its constituent assets; (ii) there is a substantial index premium for included assets; and (iii) the index premium persists even when short-selling is permitted. The price increases of the constituent assets and of the ETF itself suggest that ETF products can distort markets to some degree

    The Pottery Kilns at the Copper and Late Roman Age Site Hariachkivka 8 (Ukraine): Magnetic Prospection and Archaeological Verification

    In 2018 and 2019, archaeological field research was conducted at the settlement of Hariachkivka 8 (left bank of the Dnister River). As a result of surface surveys, the existence of two cultural layers, one of the Cucuteni-Trypillia Cultural Complex (CTCC) of the Copper Age and the second of the Cherniakhiv culture of the Late Roman Age, was confirmed. The plan of the CTCC settlement and surrounding ditch was then investigated using magnetic survey. Against the "usual" circular settlement layout, the north-western location of the "megastructure" and two other large objects placed within the ring corridor identified as possible clay extraction pits were unusual. The settlement existed in the period around 4200- 4100 BC (Trypillia BI-BII stage). Due to this fact, the kiln-like anomalies identified on the magnetic map of the settlement became the objects of further investigations, since no kilns from this period have yet been found in CTCC contexts. As a result of excavations, it was found that the anomalies are indeed kilns, but of the Cherniakhiv culture. At the same time, the uniqueness of the Copper Age settlement is not lost, as it is one of the earliest settlements in the CTCC with a circular spatial organization

    Effect of remote ischaemic conditioning on clinical outcomes in patients with acute myocardial infarction (CONDI-2/ERIC-PPCI): a single-blind randomised controlled trial.

    BACKGROUND: Remote ischaemic conditioning with transient ischaemia and reperfusion applied to the arm has been shown to reduce myocardial infarct size in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). We investigated whether remote ischaemic conditioning could reduce the incidence of cardiac death and hospitalisation for heart failure at 12 months. METHODS: We did an international investigator-initiated, prospective, single-blind, randomised controlled trial (CONDI-2/ERIC-PPCI) at 33 centres across the UK, Denmark, Spain, and Serbia. Patients (age >18 years) with suspected STEMI and who were eligible for PPCI were randomly allocated (1:1, stratified by centre with a permuted block method) to receive standard treatment (including a sham simulated remote ischaemic conditioning intervention at UK sites only) or remote ischaemic conditioning treatment (intermittent ischaemia and reperfusion applied to the arm through four cycles of 5-min inflation and 5-min deflation of an automated cuff device) before PPCI. Investigators responsible for data collection and outcome assessment were masked to treatment allocation. The primary combined endpoint was cardiac death or hospitalisation for heart failure at 12 months in the intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT02342522) and is completed. FINDINGS: Between Nov 6, 2013, and March 31, 2018, 5401 patients were randomly allocated to either the control group (n=2701) or the remote ischaemic conditioning group (n=2700). After exclusion of patients upon hospital arrival or loss to follow-up, 2569 patients in the control group and 2546 in the intervention group were included in the intention-to-treat analysis. At 12 months post-PPCI, the Kaplan-Meier-estimated frequencies of cardiac death or hospitalisation for heart failure (the primary endpoint) were 220 (8·6%) patients in the control group and 239 (9·4%) in the remote ischaemic conditioning group (hazard ratio 1·10 [95% CI 0·91-1·32], p=0·32 for intervention versus control). No important unexpected adverse events or side effects of remote ischaemic conditioning were observed. INTERPRETATION: Remote ischaemic conditioning does not improve clinical outcomes (cardiac death or hospitalisation for heart failure) at 12 months in patients with STEMI undergoing PPCI.

    Статтю присвячено вивченню юкстапозитних іменників у поетичному мовленні Ліни Костенко. Розглянуто різні лінгвістичні підходи до потрактування поняття «юкстапозит», за якими юкстапозити – це: слова, утворені складанням кількох оформлених слів або форм слів без сполучних голосних (Н. Клименко); складання кількох окремих слів у складне без сполучного голосного з обов’язковим дефісним написанням (Л. Азарова, К. Городенська, Л. Радомська, О. Стишов); одиниці синтаксичного рівня, які постали без застосування словотвірних ресурсів, не мають сформованого реального словотвірного значення (А. Нелюба). Визначено характерні ознаки юкстапозитів: утворюваність; ненормативність; функціональна одноразовість; номінативна факультативність; індивідуальна належність; словотворча похідність. Поставлено за мету здійснити структурно-семантичний і функціональний аналіз іменників-юкстапозитів поетичного мовлення Ліни Костенко. Встановлено, що характерними для індивідуального стилю письменниці є такі види юкстапозитних конструкцій: прикладкові сполуки із препозитивною прикладкою; прикладкові сполуки з постпозитивною прикладкою; словоскладання компонентів із різним граматичним родом; юкстапозити, побудовані на синонімічному зближенні компонентів; конструкції із семантично рівноправними іменниками, побудовані як парні зближення сумарної семантики, які становлять певний концепт. Виявлено, що у поетичному словнику письменниці широко вживаються різноманітні за семантикою індивідуально-авторські іменникові юкстапозити: назви спорідненості, свояцтва; назви осіб за професією, родом діяльності, соціальним станом; назви народностей, національностей; назви міфічних істот, казкових героїв; назви частин тіла людини, тварини; назви тварин, птахів, риб; назви рослин і їх плодів; назви природних явищ і географічних понять; назви населених пунктів, фортець; назви будівель, архітектурних споруд, їх елементів; назви частини доби, певних проміжків часу тощо. З’ясовано, що іменники-юкстапозити у поетичних текстах Ліни Костенко слугують конденсованості вираження думки митця, виступають як засіб стилістичного підсилення, уточнення характерної ознаки певного предмета, явища.The article is devoted to the study of juxtaposition nouns in the poetic speech of Lina Kostenko. Various linguistic approaches to the interpretation of the concept “juxtaposition” are considered, according to which juxtapositions are: words created by composing several formed words or word forms without connecting vowels (N. Klimenko); composing several separate words into a complex without connecting vowel with the obligatory hyphen writing (L. Azarova, K. Horodens’ka, L. Radoms’ka, O. Styshov); units of syntactic level, which appeared without the use of word-forming resources, do not have formed real word-forming meaning (A. Nelyuba). The characteristic features of juxtapositions are determined: formation; non-normativeness; functional disposability; nominative optionality; individual affiliation; word-formation derivative. The aim is to carry out a structural-semantic and functional analysis of nouns-juxtapositions of Lina Kostenko’s poetic speech. It is established that the following types of juxtaposition constructions are characteristic of the individual style of the writer: apposition compounds with a prepositional attachment; apposition compounds with postpositive attachment; word formation of components with different grammatical gender; juxtapositions based on the synonymous convergence of components; constructions with semantically equal nouns, formed as paired convergences of total semantics, which constitute a certain concept. It is revealed that in the poetic dictionary of the writer semantically various individual-author noun juxtapositions are widely used: names of kinship; names of individuals by profession, type of activity, social status; names of nationalities; names of mythical creatures, fairy-tale heroes; names of human and animal body parts; names of animals, birds, fish; names of plants and their fruits; names of natural phenomena and geographical concepts; names of settlements, fortresses; names of buildings, architectural structures, their elements; names of parts of the day, certain periods of time, etc. It was found that nouns-juxtapositions in Lina Kostenko’s poetic texts serve to condense the expression of the artist’s thought, act as a means of stylistic reinforcement, clarification of the characteristic feature of a certain object, phenomenon
