Published: February 2022

Визначено необхідність застосування міжнародного маркетингу підприємствами у зв’язку зі зростаючою відкритістю країн стосовно зовнішніх ринків та необхідністю удосконалювати відносини підприємств із цими ринками. Проведено аналіз визначень поняття національного маркетингу як основи для уточнення поняття міжнародного маркетингу. Виділено у структурі міжнародного маркетингу його типи, а саме: каскадний та глобальний. Зазначено, що в основі виділення типів маркетингу лежить або необхідність ураховувати в товарі чи послузі особливості зовнішніх ринків (адаптація товарів до умов зовнішнього ринку), або можливість реалізовувати їх у стандартному виконанні для всіх ринків (стандартизація товарів та послуг). Запропоновано авторський підхід, в основу якого покладено гіпотезу про те, що всі ринки доцільно оцінювати за двома критеріями: глобальних сил, що сприяють стандартизації маркетингових зусиль, та локальних сил, які змушують підприємства адаптуватися до ринкових умов окремих країн. Відповідно до вибраних критеріїв і рівня їх вимірювання, виділено чотири різновиди зовнішнього середовища: глобальне (універсальне), множинне національне (мультинаціональне), нейтральне та транснаціональне (міжнаціональне). Визначено особливості та негативні наслідки етноцентризму, які можуть виражатися як у повному ігноруванні відмінностей між внутрішнім та зовнішнім ринком, так і в розумінні необхідності враховувати специфіку міжнародних ринків, але з домінуванням національних пріоритетів та недооцінкою складності створення комплексу маркетингу для окремих країн. Досліджено визначення та зміст поняття маркетингових досліджень. Доведено, що найважливішим у системі маркетингових досліджень є інформація. Виходячи з положень сучасного маркетингу, визначено, що для кожного товару може бути побудована як трирівнева, так і дворівнева концепція його створення.

Genetic analysis of passerine birds often finds evidence of extra–pair copulations within species, but genetic evidence of intraspecific brood parasitism (IBP) and quasi–parasitism (Q–P) are relatively rare. Further, it is even rarer for genetic patterns that might indicate quasi–parasitism (resident male sires offspring through extra–pair copulations, and allows the female to lay these within the male’s nest) to be coupled with observational evidence of this behavior. In this paper, we report behavioral observations surrounding the nest of black–capped chickadee, one of the few species in which both IBP and Q–P have been detected through a genetic analysis. These were later confirmed to have young genetically mismatched with both attending parents, as well as mismatched with the attending female but sired by the attending male. The behavioral patterns associated with this nest are contrasted with the two previously reported cases of IPB/Q–P in this species, and suggest that rare ‘detection’ of quasi–parasitism may be explained by converging patterns of extra–pair behavior and the rarer strategy of intraspecific brood parasitism.

Biomass response to environmental factors in two congeneric species of Mullus, M. barbatus and M. surmuletus, off Catalano–Levantine Mediterranean coast of Spain: a preliminary approach

Published: February 2022

We analyzed the influence of some abiotic variables in the biomass distribution of these species using survey data collected over four years (2006-2009) in the Catalano-Levantine coast of Spain. The preliminary results show that variables such as time (year) and latitude feebly affect the biomass distribution of these species. Depth, by itself, is not as significant as believed, masking the influence of other variables. M. barbatus biomass distribution seems to be especially influenced by salinity and, to a lesser extent, by temperature, while only temperature seems to have a significant effect on the M. surmuletus biomass distribution. These results are consistent with the bathymetric distribution of both species, with M. barbatus showing affinity for low salinity waters and M. surmuletus for warmer waters, which may contribute to the segregation of the species.

Ecological features of Terebellida (Annelida, Polychaeta) inhabiting the intertidal and subtidal soft-bottoms of Ensenada de San Simón (NW Spain) were analysed by means of quantitative sampling. A total of 4,814 specimens belonging to five families (Ampharetidae, Pectinariidae, Terebellidae, Trichobranchidae and Sabellariidae) and ten species were collected in a variety of substrata and depths. Ampharetidae was the numerically dominant family mostly due to the abundance of Ampharete finmarchica and Melinna palmata; these species accounted for up to 94% of the total Terebellida abundance. Intertidal areas colonised by the seagrasses Zostera marina L. and Z. noltii Hornem. One thousand eight hundred and thirty-two harboured low densities of Terebellida, whereas the deeper subtidal muddy bottoms showed high abundances of ampharetids. Multivariate analyses suggested that Terebellida assemblages are highly correlated with sediment composition.

A total of 13 species of cetaceans and three species of marine turtles were found in this study. Data were collected by eight independent and self-regulated stranding networks, providing information about 1,198 marine mammal (10 odontocetii, three mysticetii and one phocidae) and 574 sea turtle stranding events between 1991 and 2008. Trends in the strandings were analysed in relation to species composition and abundance, and their geographic and seasonal distribution. The most abundant species recorded were the striped dolphin and the loggerhead turtle. Some of the strandings, such as the humpback whale, harbour porpoise, hooded seal and olive ridley turtle, were considered ‘rare’ because their distribution did not match the pattern of the study. When the north and south coasts in the study area were compared, pilot whales stranded more frequently in the north, while delphinid species stranded more in the south coast, and loggerhead turtles stranded more frequently in the north while leatherback turtles stranded more in south coast.

During the last 30 years, studies on Elysia timida (Risso, 1818) have addressed various aspects related to food sources, photosynthetic efficiency of kleptoplasts, population genetics, chemical ecology and reproductive biology, both in the Mediterranean Sea and in the Mar Menor coastal lagoon. E. timida shows a strong specific interaction with Acetabularia acetabulum, retaining functional chloroplasts for at least 45 days and obtaining extra energy in periods when food resources are scarce. It shows control of parapodia, avoiding pigment photodestruction under oversaturated light conditions. The chemical ecological relationships established between E. timida and its potential predator fish, Thalassoma pavo, have also been evaluated, and it has been found that that the extracts of the mollusc contain repellent and unpalatable polypropionate compounds. Population genetics has demonstrated the genetic divergence between populations showing high and significant values of FST and genetic distances, and at least six privative alleles that are not shared with Mediterranean populations have been detected in lagoon populations. This sacoglossan is a poecilogonic species, and its lagoon populations show a greater reproductive output than Mediterranean populations; they produce a greater number of egg masses and embyros per individual, and the capsules have a wider diameter.
Estructura del órgano estridulador y análisis de la emisión acústica de Agapanthia dahli (Richter, 1821) (Coleoptera, Cerambycidae, Lamiinae)
Authors:   Univ. Complutense de Madrid, Spain, Hernández J. M.
Published: February 2022

Agapanthia dahli (Richter, 1821) have a stridulatory organ consisting of a grooved plate or pars strindens at the dorsal side of mesonotum and a scraper or plectrum in the internal posterior margin of the pronotum. Sound is produced when the insect moves the pronotum, sliding the plectrum against the pars stridens. The structure of the signal is typically disyllabic, reflecting the bi–directional movement of pars strindens with respect to the plectrum. We describe the stridulatory organ and acoustic signals for the first time, and discuss the possible role of stridulation in this species.
Ecological genetics of freshwater fish: a short review of the genotype–phenotype connection
Authors:   University of Girona, Spain, Vidal O. , García-Marín J. L. ,   University of Girona, Spain
Published: February 2022

Molecular ecology or ecological genetics is an expanding application of population genetics which has flourished in the last two decades but it is dominated by systematic and phylogeographic studies, with relatively little emphasis on the study of the genetic basis of the process of adaptation to different ecological conditions. The relationship between genotype and adaptive phenotypes is weak because populations are often difficult to quantify and experiments are logistically challenging or unfeasible. Interestingly, in freshwater fish, studies to characterize the genetic architecture of adaptive traits are not as rare as in other vertebrate groups. In this review, we summarize the few cases where the relationship between the ecology and genetics of freshwater fish is more developed, namely the relationship between genetic markers and ecological phenotypes.

In recent decades agricultural landscapes in Catalonia have undergone a profound transformation as in most of Europe. Reforestation and urban development have reduced farmland and therefore the availability of suitable habitat for some bird species such as the little owl (Athene noctua). The outskirts of the city of Mataró by the Mediterranean Sea exemplify this landscape change, but still support a population of little owl where agriculture is carried out. Three resident little owls were monitored with telemetry weekly from November 2007 until the beginning of August 2008 in this suburban agricultural landscape. Mean home range ± SD was 10.9 ± 5.5 ha for minimum convex polygon (MCP100) and 7.4 ± 3.8 ha for Kernel 95% probability function (K95). Home ranges of contiguous neighboring pairs overlapped 18.4% (MCP100) or 6% (K95). Home range varied among seasons reaching a maximum between March and early August but always included the nesting site. Small forested patches were associated with roosting and nesting areas where cavities in Carob trees (Ceratonia siliqua) were important. When foraging in crop fields, the owls typically fed where crops had recently been harvested and replanted. All three owls bred successfully.

To test the efficiency of playback methods to survey little owl (Athene noctua) populations we carried out two studies: (1) we recorded the replies of radio–tagged little owls to calls in a small area; (2) we recorded call broadcasts to estimate the effectiveness of the method to detect the presence of little owl. In the first study, we detected an average of 8.12 owls in the 30′ survey period, a number that is close to the real population; we also detected significant little owl movements from the initial location (before the playback) to the next locations during the survey period. However, we only detected an average of 2.25 and 5.37 little owls in the first 5′ and 10′, respectively, of the survey time. In the second study, we detected 137 little owl territories in 105 positive sample units. The occupation rate was 0.35, the estimated occupancy was 0.393, and the probability of detection was 0.439. The estimated cumulative probability of detection suggests that a minimum of four sampling times would be needed in an extensive survey to detect 95% of the areas occupied by little owls.

The purpose of the research entitled Settlement of Commercial Business Disputes through Online Non-Litigation Dispute Resolution in Indonesia is to analyze the mechanism for resolving commercial business disputes through non-litigation in the form of ODR in Indonesia and its legal consequences. The research method is in the form of normative legal research, which is a method that uses statutory regulations, which are then analyzed and drawn conclusions from general matters into a specific conclusion. The results of the research obtained are, First: that the legal basis that contains and states implicitly regarding matters relating to ODR is contained in Law Number 30 of 1999 concerning Arbitration and Alternative Dispute Resolution, namely, the contents of the legal regulations also do not provide much clarity. Details on how the conditions for ODR are carried out, the ODR mechanism, and other explanations. Second, the Inconsistency Norm that occurs in regulations relating to dispute resolution through non-litigation ODR, namely between several articles in the AAPS Law, there is a discrepancy or contradiction between the rules or articles that apply, so that the legal rules become vague and unclear. Where according to several articles of the AAPS Law it is stated that the Arbitration dispute resolution process must be written, while according to other articles of the AAPS Law it can be online. There is a legal ambiguity in the non-litigation dispute resolution mechanism through ODR, so that the parties feel that there are no clear directions or instructions in resolving cases, this makes the process of non-litigation dispute resolution mechanisms through ODR not well directed, due to disharmony or inconsistency the rule of law, so that the rule of law becomes vague, vague and unclear. The solution to these legal issues is that the government should make legal regulations that specifically regulate ODR or revise Law Number 30 of 1999 and add articles related to ODR. To the Government to provide websites and institutions that can specifically handle non-litigation dispute resolution through ODR to handle commercial business dispute resolution.

La infección por SARS-CoV-2, al igual que otras infecciones víricas, produce una gran variedad de manifestaciones cutáneas. Sin embargo, el angioedema no es frecuente y se presenta generalmente asociado a urticaria y a síntomas respiratorios. Su aparición tampoco es habitual en pacientes que además están en tratamiento con IECA. Parece que el mecanismo por el cual el virus y los IECA producen angioedema es similar, alterando la regulación de los receptores ACE-2 y aumentando los niveles de bradicinina. Es razonable pensar que el SARS-CoV-2 pudiera actuar como un factor precipitante al combinarse con estos productos.

Se debe tener una alta sospecha clínica para las encefalitis autoinmunes ya que comúnmente se confunden con patologías psiquiátricas. El pronóstico de estos pacientes depende del inicio precoz del tratamiento.
Presentamos el caso de una mujer de 21 años, con alteraciones conductuales y alucinaciones de un mes de evolución, que desarrolla cefalea y fiebre. Tras el estudio, se le diagnosticó encefalitis anti-NMDAR.
НАКОПИЧЕННЯ ВАЖКИХ МЕТАЛІВ У ПРОРОСТКАХ СОНЯШНИКУ ПІД ВПЛИВОМ КАДМІЄВОГО СТЕСУ
Authors: Фу Юаньжі , Троценко В. І.
Published: February 2022

Стійкою тенденцією останніх десятиліть є стрімке зростання забруднення грунту важкими металами. Особливу небезпеку становлять метали, які не відіграють суттєвої ролі у житті рослин, але можуть накопичуватися у рослинах та мігрувати харчовим ланцюгом. Одним із таких елементів є кадмій, період напіввиведення якого з організму людини складає більше 50 років. Для селекційних програм, спрямованих на створення сортів із низьким рівнем накопичення кадмію, важливим є розуміння ролі генотипу в процесах надходження металу до різних частин рослин. Дослідження проводились на селекційних зразках соняшнику, виділених за методикою вегетаційного оцінювання в Сумському НАУ в 2018 році. За результатами оцінювання лінія 62\3 характеризувалася низьким, а лінія JB231AC – високим рівнем стійкості до накопичення кадмію. У 2020 році насіння зразків було пересіяно в умовах Науково-технологічного інституту м. Хенань. Досліджували 20-денні проростки соняшнику, що вегетували у пластикових контейнерах з розчином Хогланда. Із рівномірно розвинених рослин було сформовано 4 вибірки, які протягом 7 днів знаходились у розчині CdCl2 • 2,5 H20 з концентрацією 0; 25; 50 та 100 мкМ. Для аналізу зразки розчиняли у нітратній кислоті. Визначення вмісту металів проводили на атомно-адсорбційному спектрофотометрі (ICP-OES, Optima 2100DV, Perkin Elmer). В обох зразків було відмічено стійкий тренд до зменшення висоти рослин та загальної маси проростків із збільшенням концентрації кадмію. Різниця між зразками за згаданими показниками нівелювалася при концентрації 50 і більше мкМ. У випадку із висушеними частинами рослин статистично суттєвий вплив кадмію виявлено при концентрації 50 і більше мкМ для показника маси сухої речовини коренів та при концентрації 100 мкМ для показника маси надземної частини. Встановлено, що пороговою концентрацією, яка забезпечувала суттєву різниці між показниками вмісту кадмію в коренях та стеблах, було 100 мкМ. Порівняно із зразком JB231AC, зразок 64\2 мав вищий вміст кадмію у коренях на 23 % та на 12 % у надземній частині. Відносно Li, Nі, та Sr суттєва різниця між зразками здебільшого спостерігалася за концентрації 25 та 50 мкМ. Накопичення і розподіл кадмію в рослинах мають значний зв’язок з видами, сортами, частинами та середовищем вирощування і в кінцевому підсумку призводять до різного накопичення та розподілу в різних частинах рослин. Встановлено зворотну залежність між концентрацією кадмію та концентраціями літію та нікелю, що може бути зумовлено генотипними особливостями, але не виключається наявність антагонізму між накопиченням цих металів. Однак таке твердження потребує додаткових досліджень. Загалом дослідження підтвердили достатній рівень ефективності вегетативної оцінки вихідного матеріалу соняшнику на стійкість до накопичення кадмію та стабільність цієї ознаки в наступних поколіннях.

Previous studies have reported in vitro antioxidant and inhibitory activity on xanthine oxidase of Jasminum subtriplinerve Blume, Oleaceae, which suggested the potential prevention of gout and supplementary treatment. This study evaluated analgesic, anti-inflammatory, and hypouricemic effects of the 50% ethanolic extract of J. subtriplinerve (EEJS) at the oral doses of 800 and 1200 mg/kg in mice. For acute oral toxicity, after oral administration of single doses of EEJS; mortality and toxic signs in male and female mice were noticed within 72 hours and 14 days. The analgesic effect was observed in acid acetic induced writhing in mouse model within 40 minutes. The anti-inflammatory effect was determined in mice-induced edema by 1% carrageenan. The hypouricemic effect was evaluated in mice with the peritoneal injection of potassium oxonate inducing acute and chronic hyperuricemia. The results showed that there was not any toxic sign in mice given orally at the maximum dose (Dmax) of 20 g EEJS/kg. At the dose of 800 and 1200 mg/kg, EEJS did exhibit analgesic effect until 40th minute. EEJS 1200 mg/kg expressed acute anti-inflammatory effect. EEJS had no acute hypouricemic effect at the oral doses of 800 and 1200 mg/kg. When given to mice with chronic hyperuricemia, 800 mg/kg EEJS reduced 30-44% blood uric acid concentration compared to pathological group. In conclusion, EEJS did not cause any toxic sign in mice at the Dmax of 20 g/kg. This extract had analgesic and chronic hypouricemic effects at the oral dose of 800 mg/kg in mice.

The nanosized systems involving Pt(IV) complexes with antitumor activity are obtained by their solubilization via amphiphilic copolymers of N-vinylpyrrolidone and (di)methacrylates synthesized by the radical copolymerization in toluene without any polymer chain growth terminating agents. The resulting systems are investigated by a complex of physico-chemical methods (IR spectroscopy, DLS, TEM, cyclic and square-wave voltammetry) and quantum chemical simulation. The Pt(IV) complexes are shown to have cytotoxic effects on A-172 tumor cells and the corresponding cytotoxicity indices (IC50) are determined. The amphiphilic copolymers under consideration are promising modern platforms and delivery vehicles for biologically active compounds.
