Authors: Aiello Dalia , Vitale Alessandro , Perrone Giancarlo , Tessitori Matilde , Polizzi Giancarlo
Published: December 2020

This research evaluates biological control agents (BCAs) and fungicide alone and in combination for the management of decline caused by multiple fungi on milkwort (Polygala myrtifolia). Four experiments were performed in a greenhouse within a nursery located in Catania province (southern Italy). The activity of fungicides and biological control agents was evaluated by calculating the plant mortality (%) and recovery frequency (%) of different fungi associated with symptomatic tissue. Comprehensively, boscalid + pyraclostrobin and fosetyl-Al showed the best results in managing disease complex on milkwort. Biological control agents provided, on average, the lowest performances; nevertheless, in most cases, they were able to significantly reduce multiple infections and sometimes when combined with fungicide enhanced the effectiveness. The molecular analysis of 86 isolates obtained from symptomatic tissue allowed to identify the fungi involved in the disease as Calonectriapauciramosa, C. pseudomexicana, Fusariumoxysporum, Neocosmospora solani (syn. F. solani) and binucleate Rhizoctonia AG-R. Calonectriapseudomexicana never reported on milkwort and in Europe was inoculated on P. myrtifolia potted healthy cuttings and produced crown and root rot after 40 days. Our findings represent the first worldwide report about disease complex of milkwort caused by several fungi (Calonectria spp., Fusarium spp. and binucleate Rhizoctonia) and on the effects of integrated control strategies to manage this disease in the nursery.

Published: December 2020

Martensitic transition and magnetic response of Ni50−x Pdx,y Mn36 Sn14−y (x = 0, 1, 2 and y = 0, 1) Heusler alloys were analysed. The crystalline structure of each composition was solved by X-ray diffraction pattern fitting. For x = 1 and 2, the L21 austenite structure is formed and, for y = 1, the crystallographic phase is a modulated martensitic structure. From differential scanning calorimetry scans, we determine characteristic transformation temperatures and the entropy/enthalpy changes. The temperatures of the structural transformation increase with the addition of Pd to replace Ni or Sn, whereas the austenitic Curie temperature remains almost unvarying. In addition, the magneto-structural transition, investigated by magnetic measurements, is adjusted by suitable Pd doping in the alloys. The peak value of the magnetic entropy changes reached 4.5 J/(kg K) for Ni50Mn36Sn13Pd1 (external field: 50 kOe).
Human-Like Arm Motion Generation: A Review
Authors: Gulletta Gianpaolo , Erlhagen Wolfram , Bicho Estela
Published: December 2020

In the last decade, the objectives outlined by the needs of personal robotics have led to the rise of new biologically-inspired techniques for arm motion planning. This paper presents a literature review of the most recent research on the generation of human-like arm movements in humanoid and manipulation robotic systems. Search methods and inclusion criteria are described. The studies are analyzed taking into consideration the sources of publication, the experimental settings, the type of movements, the technical approach, and the human motor principles that have been used to inspire and assess human-likeness. Results show that there is a strong focus on the generation of single-arm reaching movements and biomimetic-based methods. However, there has been poor attention to manipulation, obstacle-avoidance mechanisms, and dual-arm motion generation. For these reasons, human-like arm motion generation may not fully respect human behavioral and neurological key features and may result restricted to specific tasks of human-robot interaction. Limitations and challenges are discussed to provide meaningful directions for future investigations.

Published: December 2020

Swimming is a popular youth sport that is considered beneficial for cardiovascular fitness. However, the potential inflammatory outcomes of high intensity swimming in younger swimmers are unclear, as is the response of irisin, a myokine released during exercise with anti-inflammatory properties. This study compared the plasma concentrations of interleukins 1-beta (IL-1β), 6 (IL-6), 10 (IL-10), tumor necrosis factor alpha (TNF-α) and irisin in response to intense swimming between adolescent and adult male swimmers. Thirty-two swimmers (16 adolescents, 14 ± 1 years; 16 adults, 21.5 ± 3.1 years) completed a high intensity interval swimming trial. At rest, only TNF-α was higher (33%, p < 0.05) in adolescents compared with adults. There was an overall significant increase in IL-1β from pre- to post-swimming (3% in adolescents, 24% in adults), but no significant interaction. IL-10 significantly increased in both groups (+34% in adolescents, +56% in adults). IL-6 and TNF-α increased significantly (+32% and +26%, respectively) in adults, but not in adolescents (+2% and −9%, respectively). Adults showed a small, but significant decrease in irisin (−5%), with no change in adolescents. The lack of an IL-6, TNF-α and irisin response to intense swimming in adolescent swimmers may suggest a blunted inflammatory and myokine response following high intensity exercise in trained youth.

Multicomponent interventions for enhancing primary care: a systematic review
Authors: Jimenez Geronimo , Matchar David , Koh Gerald Choon-Huat , Car Josip
Published: December 2020

Background

Many countries have implemented interventions to enhance primary care to strengthen their health systems. These programmes vary widely in features included and their impact on outcomes.

Aim

To identify multiple-feature interventions aimed at enhancing primary care and their effects on measures of system success — that is, population health, healthcare costs and utilisation, patient satisfaction, and provider satisfaction (quadruple-aim outcomes).

Design and setting

Systematic review and narrative synthesis.

Method

Electronic, manual, and grey-literature searches were performed for articles describing multicomponent primary care interventions, providing details of their innovation features, relationship to the ‘4Cs’ (first contact, comprehensiveness, coordination, and continuity), and impact on quadruple-aim outcomes. After abstract and full-text screening, articles were selected and their quality appraised. Results were synthesised in a narrative form.

Results

From 37 included articles, most interventions aimed to improve access, enhance incentives for providers, provide team-based care, and introduce technologies. The most consistent improvements related to increased primary care visits and screening/preventive services, and improved patient and provider satisfaction; mixed results were found for hospital admissions, emergency department visits, and expenditures. The available data were not sufficient to link interventions, achievement of the 4Cs, and outcomes.

Conclusion

Most analysed interventions improved some aspects of primary care while, simultaneously, producing non-statistically significant impacts, depending on the features of the interventions, the measured outcome(s), and the populations being studied. A critical research gap was revealed, namely, in terms of which intervention features to enhance primary care (alone or in combination) produce the most consistent benefits.

Published: December 2020

Background

Polypharmacy is common in heart failure (HF), whereas its effect on adverse outcomes in patients with HF with preserved ejection fraction (HFpEF) is unclear.

Aim

To evaluate the prevalence, prognostic impacts, and predictors of polypharmacy in HFpEF patients.

Design and setting

A retrospective analysis performed on patients in the Americas region (including the US, Canada, Argentina, and Brazil) with symptomatic HF and a left ventricular ejection fraction ≥45% in the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) trial, an international, randomised, double-blind, placebo-controlled study conducted during 2006–2013 in six countries.

Method

Patients were categorised into four groups: controls (<5 medications), polypharmacy (5–9 medications), hyperpolypharmacy, (10–14 medications), and super hyperpolypharmacy (≥15 medications). The outcomes and predictors in all groups were assessed.

Results

Of 1761 participants, the median age was 72 years; 37.5% were polypharmacy, 35.9% were hyperpolypharmacy, and 19.6% were super hyperpolypharmacy, leaving 7.0% having a low medication burden. In multivariable regression models, three experimental groups with a high medication burden were all associated with a reduction in all-cause death, but increased risks of HF hospitalisation and all-cause hospitalisation. Furthermore, several comorbidities (dyslipidemia, thyroid diseases, diabetes mellitus, and chronic obstructive pulmonary disease), a history of angina pectoris, diastolic blood pressure <80 mmHg, and worse heart function (the New York Heart Association functional classification level III and IV) at baseline were independently associated with a high medication burden among patients with HFpEF.

Conclusion

A high prevalence of high medication burden at baseline was reported in patients with HFpEF. The high medication burden might increase the risk of hospital readmission, but not the mortality.
Effect of tillage practices, fertilizer treatments and crop rotation on yield of maize (Zea mays L.) hybrids
Authors: Bramdeo Karamchand , Rátonyi Tamás
Published: December 2020

This research was conducted at the University of Debrecen Látókép Research Station and is part of an ongoing long-term polyfactorial experiment. The impact of three tillage systems (Mouldboard plowing-MT, Strip tillage-ST, Ripper tillage-RT) and two levels of fertilizer treatments (N80 kg ha-1, N160 kg ha-1) along with a control (N0 kg ha-1) on the yield of maize hybrids (Armagnac- FAO 490 & Loupiac-FAO 380) cultivated in rotation with winter wheat was evaluated during a two-year period (2017–2018).
Amongst the three tillage treatments evaluated, ripper tillage (RT) had the highest average yield (10.14 t ha-1) followed by mouldboard tillage (MT) and strip tillage (ST) with 9.84 and 9.21 t ha-1 respectively. Yield difference between RT and MT was not significant (P>0.05), as compared to ST (P<0.05). Soil moisture content varied significantly with tillage practices and was highest in ST, followed by RT and MT (ST>RT>MT). Yield of RT was 7–9% higher than MT in monoculture plots, while MT reign superior in biculture plots (monoculture: RT>MT>ST; biculture: MT>RT>ST).
A positive interaction between tillage and fertilization was observed, with higher yield variation (CV=40.70) in the non-fertilized (N0) plots, compared to those which received the N80 (CV=19.50) and N160 kg ha-1 (CV=11.59) treatments.
Incremental yield gain from increase fertilizer dosages was significantly higher in monoculture, compared to biculture. There was no significant difference in yield between N160 and N80 in the biculture plots (12.29 vs 12.02 t ha-1). However, in monoculture plots, N160 yield was 23% higher than the N80 kg ha-1 (N160=11.74 vs N80=9.56 t ha-1).
Mean yield of maize in rotation with winter wheat was 28% (2.47 tons) higher than monoculture maize. The greatest benefit of crop rotation was observed in the control plots (N0) with an incremental yield gain of 4.39 tons ha-1 over monculture maize (9.92 vs 5.43 t ha-1).
Yield increased with higher fertilizer dosages in irrigated plots. Fertilizer application greatly increased the yield of maize and accounted for 48.9% of yield variances. The highest yield (11.92 t ha-1) was obtained with N160 kg ha-1 treatment, followed by N80 kg ha-1 (10.38 t ha-1) and N0 kg ha-1 (6.89 t ha-1) respectively.
Overall mean yield difference between the two hybrids was not statistically significant, however, yield of FAO 380 was 3.9% higher (9.06 vs. 8.72 t ha-1) than FAO 490 in monoculture plots, while in biculture plots, FAO 490 was 4.1% higher than FAO 380.
Average yield in 2018 was 13.6% (1.24 t ha-1) higher than 2017 for the same set of agrotechnical inputs, thus, highlighting the significant effect of cropyear.
Armagnac (FAO 490) cultivated in rotation with winter wheat, under ripper tillage and N80 kg ha-1 is the best combination of treatments for optimum yield.

Published: December 2020

Apple production has seen a decline in yields in recent years, primarily due to ecological factors such as drought, water stress, water scarcity, uneven rainfall distribution, frost damage and hail damage. Ecological factors that are harmful to the plant can be eliminated by human intervention, irrigation or the use of hail net. In our study, we investigated the positive effects of hail net on the development of plant water potential as the vegetation progressed, in non-irrigation area with temperature and humidity. Water potential values were determined using a field osmometer. Confirmed the positive effect of the ice protection net in the apple orchard of Early Gold and Golden Reinders. Our results were supported by statistical analyzes our results.

The role of turf serving animal husbandry is significantly declining with the decreasing number of grazing livestock in Hungary. Accordingly, the area of under-utilized or non-utilized turfs is increasing. At the University of Debrecen, Institutes for Agricultural Research and Educational Farm, Karcag Research Institute we studied four types of turf utilization in three repetitions on a salt meadow with Alopecurus pratensis. As a result of the performed examinations, we identified the composition of the flora structure on the investigated area and we measured carbon-dioxide circulation and soil moisture.
Examination of different fungicides against Macrophomina phaseolina in laboratory conditions
Authors: Csüllög Kitti , Tarcali Gábor
Published: December 2020

In Hungary, sunflower is the third most important arable crop, which has a lot of pathogenic fungi. One of these fungi is the Macrophomina phaseolina, which is a well-known fungus in all over the world, since this pathogen has more than 700 host plants. In Hungary, several host plants can be found as well. The M. phaseolina produces microsclerotia, which can survive in the soil and residues for almost 10 years. For now, there is no efficient treatment against this pathogen because of this fungus, since it is extremely resistant and cannot be destroyed easily. The only effective treatment against the fungus is genetic defence. In this study, three different fungicides were tested in vitro against the fungus. The Mirage (prochloraz) seemed to be the most effective fungicide as it completely arrested the hyphal growth. In contrast, the Amistar Xtra (azoxystrobin and ciprochonazol) has only a minor effect on the growth of M. phaseolina. Thirdly, the Retengo (pyrachlostrobin) arrested the hyhpal growth of the fungus with 71% at 100 ppm, in other words, the use of this fungicide seems promising.

El Martín Fierro libertario. Problemáticas, resignificaciones y continuidades en las lecturas ácratas del poema durante la primera mitad del siglo XX
Authors: Casas Matías Emiliano
Published: December 2020

En este artículo se estudia la apropiación en clave libertaria del Martín Fierro, el famoso poema escrito por José Hernández en la década del setenta del siglo XIX. Se considera que la utilización del texto por parte de agentes de esa ideología no necesariamente reprodujo imágenes levantiscas e insumisas del gaucho. Las representaciones anarquistas de la gauchesca tuvieron que integrarse a contextos complejos, tanto en el ámbito literario como político, que incidieron en las posibilidades para reinterpretar al gaucho Fierro. Por ese motivo, este trabajo se extiende hasta mediados del siglo XX, cuando la Argentina era gobernada por el peronismo. A partir del registro de publicaciones anarquistas y de las actividades político-culturales organizadas por instituciones y agrupaciones adeptas, junto con el acervo documental elaborado por los payadores libertarios más el análisis de las producciones de Alberto Ghiraldo, se pretende develar nuevas reflexiones sobre los usos ácratas del Martín Fierro.
Migraciones y movilidades de argentinos y argentinas: revisión crítica de un campo de estudios en desarrollo (1960-2020)
Authors: Rivero Patricia Jimena , Navarro-Conticello Jose
Published: December 2020

Se presenta una revisión crítica del desarrollo histórico del campo de estudios sobre migraciones y movilidades de argentinos y argentinas, entendido como el conjunto de publicaciones académicas destinadas a estudiar los procesos de emigración, inmigración y retorno de personas de esa nacionalidad. Con base en los factores predominantes que originan la movilidad, usualmente se distinguen tres etapas: fuga de cerebros (1960-1975), exilio político (1976-1983), migraciones económicas (1984-2004). En este estudio se propone una cuarta etapa, denominada “migraciones y movilidades” (2005-2020). El análisis permite establecer que el escenario global y los contextos políticos, sociales y económicos de Argentina han orientado la producción académica en determinadas direcciones, priorizándose ciertas categorías de análisis y desplazándose otras. Se destacan las contribuciones de los campos de estudios sobre ciencia, tecnología y sociedad y educación superior en el abordaje de las migraciones calificadas.
“Los desaparecidos empiezan a hablar”: una aproximación histórica a la producción testimonial de los sobrevivientes de la dictadura argentina desde el exilio (1976-1983)
Authors: González Tizón Rodrigo
Published: December 2020

Este artículo plantea un abordaje histórico de la producción testimonial que realizaron desde el exilio los sobrevivientes de los centros clandestinos de detención (CCD) de la última dictadura argentina. En este marco, se reconstruyen los principales ámbitos de circulación pública de sus relatos sobre el cautiverio y se ofrece un análisis de su evolución a lo largo del período 1976-1983. El trabajo se propone no sólo recuperar su aporte específico a la lucha contra el régimen militar, sino también tensionar la construcción de sentidos que postula el silenciamiento público de los sobrevivientes a causa de las acusaciones de “traición”. Finalmente, se exploran las modulaciones específicas que asumieron, en la producción testimonial de los sobrevivientes, una serie de fenómenos que atravesaron al movimiento antidictatorial exilar en su conjunto: la elaboración de saberes tempranos sobre el dispositivo represivo clandestino para su difusión en el extranjero, la relación entre las lógicas políticas revolucionaria y humanitaria en el ejercicio de la denuncia, la naturaleza transnacional de las redes de activismo antidictatorial y la construcción de diferentes categorías de víctimas de la violencia represiva.
A correct method to calculate the IDD value added indicator in the Brazillian higher education quality assurance framework
Authors: ter Haar Ewout
Published: December 2020

This paper investigates the value-added indicator used in the Brazilian higher education quality assurance framework, the so-called IDD indicator for undergraduate programmes (“Indicator of the difference between observed and expected outcomes''). The two main claims are that since 2014 this indicator is calculated incorrectly and that this mistake has relevance for public policy. INEP, the educational statistical agency responsible for educational quality indicators in Brazil, incorrectly uses multilevel modeling in their value-added analysis. The IDD indicator is calculated by estimating a varying intercept linear mixed model, but instead of identifying the intercepts with the value added of courses, INEP uses the mean of the student residuals. That this was indeed the error made is shown by reproducing exactly INEP’s published values using the incorrect method with the microdata for the 2019 assessment cycle. I then compare these values to the ones obtained with the same model and same data, but using the correct value-added measure. A comparison of reliability estimates for both methods shows that this measure of internal consistency is indeed higher for the correct method. As an example of policy relevance,calculate the number of courses that would change from “satisfactory” to “unsatisfactory” and vice-versa, using the usual criteria established by INEP, if the correct method is applied.

Tujuan dari penelitian ini adalah menganalisis efektifitas pendidikan kesehatan untuk meningkatkan pengetahuan  nenek dan status gizi anak prasekolah. Merupakan penelitian kuantitatif dengan desain eskperimental, one group pre test post test design. Populasi pada penelitian ini adalah nenek sebanyak 29 orang nenek dan 29 cucunya (anak prasekolah (3-5 tahun)). Kriteria inklusi dalam penelitian ini adalah nenek yang bisa baca tulis dan bersedia ikut dalam penelitian. Teknik sampling yang digunakan adalah total sampling sehingga sampel yang digunakan adalah 29 orang nenek dan 29 cucnya (anak prasekolah (3-5 tahun)). Alat ukur yang digunakan adalah kuesioner singkat untuk mengukur data sosiodemografi nenek (umur, pendidikan terakhir dan pekerjaan). Leaflet tentang makanan bergizi seimbang diberikan kepada nenek saat mengikuti pendidikan kesehatan. Pengetahuan diukur dengan kuesioner. Status gizi diukur dan dicatat pada lembar observasi. Pengetahuan nenek dan status gizi anak prasekolah dianalisis dengan menngunakan t- test. Hasil analisis dengan t-test menunjukkan bahwa terjadi peningkatan pengetahuan yang dapat dilihat dari hasil pre test yang menyatakan mayoritas nenek memiliki tingkat pengetahuan buruk dan pada  post test pengetahuan nenek mayoritas menjadi  baik dengan p value=0,008 (p<0,01). Selain itu juga terjadi peningkatan status gizi setelah dilakukan analisis pada pres test dengan hasil mayoritas status gizi anak prasekolah yaitu buruk  dan post test meningkat menjadi status gizi baik dengan p value=0,06 (p<0,001). Pendidikan kesehatan tentang makanan bergizi seimbang efektif dalam meningkatkan pengetahuan nenek dan status gizi anak prasekolah.Diperlukan pemberian pendidikan kesehatan yang terus menerus dari tenaga kesehatan atau lembaga lainnya kepada nenek yang mengasuh cucunya karena meskipun nenek telah berhasil mengasuh orang tua anak usia sampai dewasa, tetapi mayoritas mereka tidak  memahami jenis makanan bergizi seimbang yang diperlukan  cucunya dalam satu hari sehingga akan  berdampak kepada kurang atau buruknya status gizi anak prasekolah

Toplumsal hayatın gereksinim duyduğu enerjinin kesintisiz, güvenilir, zamanında, temiz ve ekonomik yollarla üretilmesi ve en uygun fiyatlarla arz edilmesi olarak tanımlanan sürdürülebilir enerji arzı, gelişmiş ve gelişmekte olan ülkeler için büyük önem taşımaktadır. Dünya enerji karışımındaki yaklaşık beşte birlik payı ile en gelişmiş yenilebilir enerji teknolojisi olan hidroelektrik santraller ise, sürdürülebilir enerji arzının tüm dünyada olduğu gibi Türkiye’de de sağlanması açısından kritik öneme sahiptir. Hidroelektrik santrallerde tüm elektrik üretim tesislerinde olduğu gibi vardiyalı bir çalışma programı bulunmaktadır. Bu sürekli üretim tesislerinde gerçekleşebilecek olan uzun süreli arızaların engellenmesini ve üretimin kesintisiz bir şekilde devam edebilmesini sağlayan personellerin işletmenin istekleri ve yasal yükümlülükler doğrultusunda analitik olarak çizelgelenmesi önemli bir husustur. Buradan hareketle bu çalışmada, bir hidroelektrik santralde çalışan personellerin çizelgelenmesi problemi ele alınmıştır. Problemin çözümü için kısıt programlama ve hedef programlamanın entegre edildiği model literatürde ilk defa önerilmiştir. Gerçek veriler ile oluşturulan bu entegre modelin çözümü neticesinde 3 vardiyada çalışan 28 personel için 31 günlük optimal bir çizelge elde edilmiştir. Elde edilen yeni çizelgede vardiya ekipleri arasında adaletli ve dengeli bir atama yapılarak işletmenin istekleri ve personelin memnuniyeti sağlanmıştır.

Yapıştırma bağlantıları, farklı bağlantı geometrilerinde oluşturulabilmektedir. Yapıştırma bağlantı tasarımlarında yoğun bir şekilde kullanılan ve üzerinde çok sayıda araştırma yapılmış yapıştırma bağlantı şekillerinden birisi de tek tesirli bindirme bağlantılarıdır. Yapılan çalışmalar sonucunda tek tesirli bindirme bağlantılarının bindirme uçlarında oluşan gerilme yığılmalarının hasarın oluşmasında etkin rol oynadığı belirtilmiştir. Tek tesirli bindirme bağlantılarında, bindirme uçlarında, malzeme azaltılması yapılmasının gerilme yığılmalarını düşürdüğü ve bunun sonucu olarak bağlantı dayanımının arttığı yapılan çalışmalardan anlaşılmaktadır. Dolayısıyla, yapıştırılan malzemelerin bindirme uçlarında malzeme azaltılmasının, farklı bağlantı geometrilerinde dayanıma etkisinin araştırılması önemli olmaktadır. Yapılan bu çalışmada, çekme yüküne maruz bırakılmış boru yapıştırma bağlantıları modellenerek, yapıştırılan boruların bindirme bölgesindeki farklı uç geometrilerinin bağlantı mukavemetine etkisi bir sonlu elemanlar analiz programı olan ANSYS kullanılarak araştırılmıştır. Yapılan çalışmada ilk olarak yapıştırılan boruların uç kısımlarındaki et kalınlığının bağlantı dayanımına etkisi araştırılmıştır. Daha sonra, borunun bindirme bölgesi boyunca et kalınlığı, bindirme ucundan itibaren farklı uzunluklarda modellenerek boru ucu uzunluk değişiminin bağlantı dayanımına etkisi çekme yükü altında araştırılmıştır. Sonuç olarak bu çalışma şartlarında ideal tasarımın Model-4 tasarımı olduğu bulunmuştur. Bu tasarımda yapıştırma bağlantılarında kritik bölge olan yapıştırıcı tabakasının dayanımı % 20,5 oranında artmıştır.

El artículo presenta los ritos fúnebres del pueblo indígena Guajiro (Wayuu) del noroeste de Venezuela. De acuerdo a sus creencias, el pasaje de la vida terrenal a la eterna se divide en varias etapas, cada una acompañada por una serie de rituales, muy importantes para la vida social. Los más conocidos son dos velorios, en particular el segundo cuyo elemento clave es la exhumación de los restos fúnebres y la despedida defi nitiva del difunto. Destaca en ellos el papel de la fi gura femenina. Cabe subrayar que el rol decisivo para el cumplimento de dichos rituales desempeñan los sueños.

Published: December 2020

Thermal analysis of semiconductor devices includes determination of thermal resistance of the chip, the case and the heatsink separately. Nowadays, the thermal analysis is carried out with the thermal structural functions obtained by the numerical deconvolution method. In this paper we experimentally show a possibility of performing the thermal analysis and determining the junction-to-case thermal resistance with the analytical thermal structure functions applied to certain diodes and transistors. The proposed
technique can be used to improve the quality of thermal design and also in the screening tests of semiconductor devices, when it is necessary to know separate thermal resistances of the components.
Meteorological measurements and observations at Zákupy in 1718-1720
Authors: Brázdil Rudolf , Valášek Hubert
Published: December 2020

Meteorological observations of the physician Johann Carl Rost at Zákupy (north Bohemia) in the years 1718-1720, published in the overviews of meteorological observations from several European localities by a Wrocław physician Johann Kanold, are analysed. Whereas from October 1718 to December 1719 and from April to December 1720 it is only summary monthly information, from 21 December 1719 to 31 March 1720 Rost performed three times a day measurements of air temperature and pressure and observations of the wind direction and the course of the weather. These records are the object of detailed climatological analysis, completed by the reconstructed surface pressure field of these months. The summarising monthly information is compared with accessible data of Czech narrative sources. Rost's observations are so far the oldest systematic instrumental measurements in the Czech Lands.
Always the Sun: The Uniqueness of Sun Exposure in Tourism
Authors: Franco Maayan , Shani Amir , Poria Yaniv
Published: December 2020

Sun exposure, although beneficial and enjoyable, has negative consequences, most prominently an increased risk of developing skin cancer. While sunbathing and other forms of sun exposure play a major role in tourism, they have been scarcely researched, and the objective of this study is to bridge this gap in the literature. The study examines the differences between the tourism and routine sun exposure patterns, attempting to reveal when and why individuals perceive sun exposure as dangerous. For this exploratory study, in-depth, semistructured interviews (N= 31) were conducted. The findings revealed three distinct behavioral patterns under different circumstances: (1) during everyday activities, participants did not use protection, as they did not perceive this exposure as dangerous; (2) at the beach or pool during nontourist leisure pastime, exposure to the sun is perceived as dangerous and protection is routinely used; and (3) in the course of vacations abroad, participants tend to expose themselves to the sun intensively, including for tanning purposes, without proper adherence to the use sun protection measures. These findings are consistent with the view of tourist spaces serve as "liminal zones" that allow individuals to take risks. The study suggests that relevant stakeholders such as public health authorities, tourism marketers, and holiday destinations should act to promote responsible sun exposure in the tourist context, to prevent skin cancer and other sunrelated diseases.
