У статті досліджено сутність та роль у сучасному світі міжрегіональних економічних зв’язків. Визначено найбільші торговельні партнери України. Проаналізовано динаміку сальдо експорту-імпорту товарів і послуг України. З’ясовано, що міжрегіональні зв’язки є потужним інструментом, який треба правильно використовувати, оскільки він може призводити не лише до позитивних, але й до негативних результатів. При створенні міжрегіональних зв’язків необхідно стежити за балансом експорту-імпорту (торговельним дефіцитом), а також прагнути використовувати й розвивати власні конкурентні переваги. Ефективність міжрегіональних економічних зв’язків перебуває в прямій залежності від стадії розвитку країни. Для країн, що розвиваються, проблеми можуть викликатися високою часткою експорту сировини. Для розвинутих країн проблеми викликаються високою вартістю робочої сили. На сьогодні конкурентоспроможність України зумовлена передусім низькою вартістю робочої сили, але це не є довготривалою перевагою. Тому в цей час бажано розвивати промисловість та послуги, які володіють новітніми технологіями, включаючи смарт-спеціалізацію, та можуть забезпечити високі конкурентні позиції України на світовому рівні.

The origin of the money, endogeneity of money supply and balance of payments: Post Keynesian approach
Authors: TEKGÜL Yelda
Published: September 2020

Discussions about the origin of the money object are represented in two separate streams as orthodox and heterodox. Orthodox flow is expressed as a Metallist approach while looking at money as a means of exchange, heterodox flow is called Cartalist and emphasizes the phenomenon of authority in the object defined as money. Orthodox current sees the money supply as an inventory and external variable that can be increased and decreased by the central bank (CB) according to the money holding preferences of the people and money is demanded only for transaction purposes. The Mundell-Fleming Model (MFM), which is included in this flow and adds the balance of payments to analysis, accepts the money supply only endogenously in the fixed exchange rate system. The aim of this study is to explain the endogenity of money supply in an open economy within the framework of Post Keynesian economics (PKI), which is based on the fact that the investment and production process takes place in a purely monetary economy. In this framework, compensation thesis which provides an alternative explanation for open economies has brought about a new expansion that is completely different from the MFM. In this expansion, two types of financial systems are defined as overdraft and asset-based. The endogeneity of the money supply in both systems in the PK can continue to be valid. These opinions oppose the endogeneity approach of the money supply discussed in MFM, and concurrently, the externality of the money supply which exists in the flexible exchange system is not accepted.
Teacher-Researcher Development? Unpacking the Understandings and Approaches in Initial Teacher Education in Kosovo
Authors: Kaçaniku Fjolla
Published: September 2020

The teacher-researcher is a prevailing concept in the post-professionalism age of teacher education. The development of teacher-researchers is discussed alongside reforming initial teacher education programmes as research-based. At this time, there is no consensus regarding the understanding and methodologies of teacher-researcher development. The purpose of this study is to examine student teachers’ and teacher educators’ understandings of and approaches to teacher-researcher development in initial teacher education in Kosovo within the research-based education movement. The study used a qualitative research design. The data were collected through open questionnaires (n = 270 student teachers), interviews (n = 15 teacher educators), and programme content (n = 5) at two initial teacher education institutions in Kosovo. Using Healey and Jenkins’s research curriculum categories as a guiding framework, the study identified four clusters of contradictory understandings and approaches relating to teacher educator practice and programme values and goals, fragmenting the context of teacher-researcher development in Kosovo. In order to build consensus in teacher-researcher development, coordinated efforts are recommended to address the current isolated and differing understandings and practices within the broader context of initial teacher education.

Indonesia, in 2018 there were 65,602 cases (IR=24,75 per 100,000 population), with the death of 467 people (CFR=0,71%), and 85.6% of districts in Indonesia reported dengue cases. The climate becomes one of the environmental factors that play a role in the number of cases. Google scholar is used as the main source for finding articles related to DHF and climate published during 2015-2019. The inclusion criteria set forth, are articles that must be published in international journals, published in 2015-2019, must discuss Indonesia, and must assess the effect of climate change on DHF. A total of 52 articles were found, but only 6 articles met the inclusion criteria. Using various analytical methods, all articles obtain climate variability related to the incidence of DHF, through vector abundance. The dynamics of DHF is a very complex system, so it is necessary to combine additional factors other than climate to predict it. The development of an early warning and monitoring system is important, in addition to strengthening the role of households in controlling DHF.

Telehealth and telemedicine become a necessity in health services amid technological advancements so that health services can reach the wider community to remote places. Implementing telehealth and telemedicine must be accompanied by the readiness of health workers to adapt to it. The purpose of this study is to determine the readiness of health workers in developed and developing countries and the barriers that affect the readiness of health workers. The research method is a literature review. Articles are chosen through google scholar, SAGE, JSTOR, and Science Direct with the keyword â€œe-health readinessâ€, â€œtelehealth readinessâ€, and â€œtelemedicine readinessâ€. From a total of 4783 articles, there were 56 articles selected based on abstracts and measurement targets and in the end, 18 articles were taken that were full text available for review. The most common dimensions to measure the readiness of healthcare on telehealth or telemedicine are core readiness, engagement readiness, and structural readiness. The implementation in a developed country is quite good based on core readiness and engagement readiness dimensions, but it needs more improvement in the structural readiness dimension, while in developing countries, there are already some countries that run it well but most are still constrained in infrastructure and resources financial. Overall, obstacles to running telehealth or telemedicine are also affected by the lack of available technological infrastructure in a country, lack of training of health workers, and lack of capacity building for health workers so that they are less able to adapt to telehealth and telemedicine.

Published: September 2020

Magnetic method in geophysical surveys is common for its non-destructive use of sub-surface structure delineation. In this study, ground-based measurements of magnetic intensity were performed using a set of instruments in some regions of Pacitan, a city in the southern area of East Java province. Based on these measurements, data acquisition was used to identify the Grindulu faulting zone in the region of interest, potentially vulnerable to geohazards. The data were first corrected using the IGRF and diurnal corrections. A filtering technique of upward continuation at a height of 900 m was then applied to separate local anomalies from regional ones as the targeted sources in the present case. These separate anomalies and their corresponding reductions to the poles as further filtering processes were analyzed for predicting the location and direction of the fault. The results, extracted from data analysis and interpretation, show that the main path of the Grindulu is directed along the NE-SW fault line or N60oE. The resulting anomalies also reflect that the Grindulu is a normal fault with surrounding minor faults lying across the Grindulu, calling for increased awareness of vulnerability in the city to seismic threats.

Temperature measurement is important in various applications; therefore, various temperature sensors have been developed. Due to its advantages, many optical fiber-based temperature sensors have been proposed. The wavelength modulation-based optical sensor is interesting due to high accuracy. However, the complex fabrication process and high cost limit the advantages of the sensors. Therefore, we proposed a simple and low-cost Mach Zehnder interferometer (MZI) sensor using step-index plastic optical fiber (SI-POF). Performance characterization of the sensor to temperature variation is presented. The sensor consists of two tapers at several distances, forming an interferometer. The first taper was designed to be steep to allow excitation of cladding modes, while the second taper was gradual to suppress power loss. Characterizations were done in terms of sensitivity, hysteresis, and repeatability by analyzing the output spectrums recorded by the spectrometer at various environment temperatures, 35oC to 85oC, with an increment of 10oC. The results showed that the sensor has a sensitivity of 0.0431 nm/oC and a correlation coefficient of 0.9965. Hysteresis of 6.9×10-3 was observed. In terms of repeatability, the sensor shows a maximum deviation, ±3oC, which was mainly resulted from the fluctuation of the oven temperature. Despite its high deviation, the sensor has advantages of simple fabrication, low cost, robust, and low power loss, which make it a good candidate for temperature sensors.

The coral reef ecosystem is one of the typical tropical ecosystems with high biodiversity which has an important role both biologically, ecologically, physically as well as socially and economically. Several coral reef areas in Indonesia were reported to have suffered damage, not only due to climate change which has an impact on rising sea surface temperatures and ocean acidification but also due to anthropogenic factors and irresponsible management of marine tourism. This study aimed to analyze the condition of coral reefs based on covering in Pramuka Island, which is one of the famous tourist destinations in the Seribu Islands. The study was conducted using Line Intercept Transect (LIT) method at predetermined coordinate points. The results showed that the dominant coral reef life form was Acropora Submassive (ACS), namely 18.9%, and Acropora Branching (ACB) as much as 12.48%. Besides, the types of life forms found were coral foliase (9.42%), Miliepora Coral (9.2%), Coral Massive (4.8%), Acropora Encrustring (4.24%), and so on. Based on the results of this study, it can be concluded that the condition of coral reefs in Pramuka Island is still relatively good with a total coral cover percentage of 72.38%. Efforts to protect the coral reef ecosystem in this area need to be considered so that its condition can be maintained.

Ongoing use of synthetic fertilizers affects soil structure. Organic manures can serve as an alternative to synthetic fertilizers. The study evaluated performance of five different types of nutrient sources (T0 =control, T1 = Urea @ 250 kg/ha, TSP @ 150 kg/ha, MoP @ 200 kg/ha, T2 = Cowdung @ 25 t/ha, T3 = Vermi compost @ 5 t/ha, T4 = fermented plant juice @ 500 ml/ha and T5 =Liquid fertilizer (Flora: consists of 20% nitrobenzene) @ 200 ml/ha) on growth and yield of broccoli, cvs. “V1=Known You” and “V2=Early Green”. Yield and yield contributing parameters such as plant height, number of leaves per plant, leaves fresh weight, length of stem, stem diameter, stem fresh weight, days taken for primary curd initiation, curd diameter, fresh weight of primary curd, no. of secondary curd per plant, fresh weight of secondary curd and yield per plot as well as hectare were measured in this experiment. In case of variety, the highest yield/plot 5.83kg and yield/ha 20.23 tons were recorded from “Early green”. Considering the nutrient factor, the highest curd weight (290.4g) per plant and yield/plot (5.01kg) were found in fermented plant juice nutrient sources. The highest benefit cost ratio BCR (3.21:1) was found in V2T4, among all other treatment combinations in respect of net return (Tk. 228934.97/ha) through the use of  fermented plant juice. Therefore, it can be concluded that fermented plant juice @ 500 ml/hacan be used to improve vegetative growth, and yield quality and quantity, and the broccoli cv. “Early Green” appears to be the best of the cultivars tested.

The experiment was conducted at the Agronomy Field laboratory, Department of Agronomy, Bangladesh Agricultural University, Mymensingh to evaluate the effect of variety and boron on the growth and yield of French bean (Phaseolus vulgaris L.) during November 2017 to March 2018. The experiment was comprised two factors involving three varieties viz. BARI Jharseem-1, BARI Jharseem-2, BARI Jharseem-3, and four Boron doses viz. 0 (No boron), 0.5, 1.0 and 1.5 kg B   ha-1. Borax was used as a source of boron. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The result exhibited that yield and its contributing characters were significantly influenced the variety and boron applications. The experimental findings revealed that the highest number of pods plant-1 (4.73), effective pods plant-1 (4.01), seeds pod-1 (3.98), 1000-seeds weight (416.53g), seed yield (1.53 t ha-1), stover yield (2.69 t ha-1), biological yield (4.22 t ha-1), and harvest index (36.03%) were highest for the variety BARI Jharseem-3. At the same time, highest number of pods  plant-1 (5.02), number of effective pods plant-1 (4.03), number of seeds pod-1 (4.04), 1000-seed weight (412.74 g), seed yield (1.54 t ha-1), stover yield (3.05 t ha-1), biological yield  (4.59 t ha-1), and harvest index (36.98 %) were recorded under boron level at 1.5 kg  ha-1. Again incase of interaction of variety and boron, highest  number of pods plant-1 (4.95), number of  effective pods plant-1 (3.98), number of seeds pod-1 (3.69), 1000-seeds weight (413.15g), seed yield (1.76 t ha-1), stover yield (3.11 t ha-1), biological yield (4.87 t ha-1) and harvest index (37.19%) were recorded in  BARI Jharseem-3 under boron level 1.5  kg  ha-1. Plant dry matter found positively correlated (r2=0.8126) with seed yield. So, it may be concluded from this experiment that cultivation of var. BARI Jharseem-3 along with 1.5 kg B ha-1 could be applied to obtain higher yield of French bean.

Published: September 2020

Vandalism is a phenomenon that we can encounter in any circumstances to public or private property. The vandalistic behaviors depend on the individuals’ perception and public tolerance; also, the human intolerance and their behavior are the factors which might influence the vandalistic acts. To understand the individuals’ perception of the vandalism issue, it is necessary to get the correct information, reason, and dimension of the act. The purpose of this research is to identify and understand the perception, thoughts, and attitudes of the students from Selçuk University toward the concept of vandalism. According to the questionnaire conducted for this purpose, 82.3% of the participants were reported to have aggressive behaviors against urban elements, and the damage to urban furniture was mostly done by writing (66.2%). The survey-research revealed that gender, which mostly involved in vandalism are males. Also, the timing of vandalism is observed at 21:00 (49%). The rate of those participants who said that they harmed the urban furniture is 15.6%, consciously stated that they had damaged the picnic table (55.1%) by writing or drawing (40%), and they had done it because the urban furniture was already vandalized (44.6%). This study will provide guidance on solutions by finding the causes and types of vandalism acts on urban furniture, which is a serious but not undetected problem in university campuses. The research indicated that people perceived vandalism as a lack of consciousness, sanction, and quality of the material and affects the quality of life. While, if enough people are aware of the problem, then the incident rate will decline, simultaneously.

A field experiment was conducted at Spices Research Sub-Centre (SRSC), Bangladesh Agricultural Research Institute (BARI), Faridpur, Bangladesh during the winter season of 2018-2019 to investigate the influences of transplanting times of seedlings and the varieties on the yield and quality of onion bulbs. There were six levels of transplanting time such as T1: November 15, T2: November 30, T3: December 15, T4: December 30, T5: January 14 and T6: January 29 under the trial. The varieties used in the study were: BARI Onion-1 and BARI Onion-4. The experiment was laid out in a randomized complete block design (RCBD) of factorial concept with three replications. The results revealed that dates of transplanting, varieties and their combined effects had significant effect on the parameters studied with minor exception. The plant height, number of leaves/plant and incidence of bolting were decreased with the passage of transplanting time. The maximum values (54.51 cm, 8.53 and 71.28%) of the aforementioned traits were recorded at early transplanting on November 15, respectively. The reduced percent of bolting (2.22%) was observed at December 30. While no incidence of bolting was found under transplanting on 14-29 January. Bulb diameter, individual bulb weight, yield, total soluble solid content and dry matter content of bulb were increased up to transplanting on December 15. Afterwards the values of aforesaid parameters were gradually decreased. The highest yield (17.65 t/ha), total soluble solid content (17.02 0brix) and dry matter content of bulb (15.95%) were obtained from December 15 insignificantly followed by December 30 (16.30 t/ha). The delayed transplanting on 29 January markedly reduced the yield (6.72 t/ha), total soluble solid content (12.58 0brix) and dry matter content of bulb (11.61%) as well. The variety BARI Onion-4 performed better in respect of yield and yield attributes but it showed inferior quality. The combined effect of December 15 x BARI Onion-4 gave the highest yield attributes and yield of onion followed by the combination of November 30 x BARI Onion-4 and December 30 x BARI Onion-4 while the values among the three treatments were statistically similar.
