Public administration tools: Forecasting vs Designing
Authors: Balatsky Evgeny , Ekimova Nataly
Published: March 2021

The article discusses the expediency of abandoning the tool of social forecasting in the practice of public administration in favor of planning and design methods. The methodological basis rests on the conceptual imperative of the impossibility to produce adequate forecasts in the modern world, which is supported by such respected researchers as Douglas North, George Soros, Nassim Taleb and Arnold Toynbee. The fairness of this thesis is illustrated using methods of comparison and analysis. The study analyses the main factors that cast doubt on the possibility and expediency of preserving the tool of social prognostics: the failure of the scenario forecast format; the need for foreknowledge of events rather than values of traditional macro-parameters; the extension of Arnold Toynbee’s principle from a historical retrospective to studying the prospects; the economic growth rate indicator (GDP) losing its indicative universality and the emergence of alternative measures of social development (Gross National Happiness, culture and environment preservation); critical attitude of the intellectual elite to the possibility of social forecasting; unreliability of the source statistics; the expectation of the end of economic growth, a change in the development regime and quantitative forecasting devaluation by the leading experts – Douglas North, Robert Lucas, Tom Piketty, Richard Heinberg; the completion of the mission of capitalism in the form of the Neo-Malthusian trap and robotomics (mass introduction of robots to the economy). The authors prove that amid fading interest in traditional forecasting, alternative prognostication methods are emerging, such as planning, designing, futurology, foresight and strategic intelligence. Devaluation of forecast tools leads to the need to change the old doctrine of public administration, based on forecast documents, to a new one implying a transition to active construction of the future through directive designing and planning. The theoretical and practical significance of the study lies in substantiating the principles of a new management system: expanding the planning and design horizon (up to 30 years); introducing a mechanism for implementing plans and projects; introducing mechanisms for pre-project foresight; creating a twolevel economic management system; and moving from the quantity paradigm to the quality one.

Indonesia is a country with high rice needs because it is a staple food for more than 90% of populations. High demand requires high stock so imports are carried out in accordance with Permendagri Number 19/M-DAG/PER/3/2014 which explains rice import standards. There are many types of rice imported into Indonesia with various quality, color and import requirements such as for health or price stabilization. In terms of colors, imported white rice is the most consumed rice by Indonesians. One example is jasmine rice from Thailand. Meanwhile, in terms of imports, both for health and stabilizing the price of japonica rice (Japan) and Basmati (Pakistan) are the most imported to Indonesia. But there are still many who are not familiar with those three rices. In this research, the three types of rice were identified by comparing the Multi-SVM algorithm and Neural Network algorithm. Image acquisition is done using a flatbed scanner which produces 90 images divided into 63 training images and 27 testing images. K-Means becomes an image segmentation method and image binary converts. Feature extraction using morphological features with the regionprop method combined with the Gray Level Co-Occence Matrix (GLCM) produces 9 features that can produce 96.296% accuracy for Multi-SVM and 88.89% Neural Network

Material & Methods: A total of 80 patients with inactive tubo-tympanic type of CSOM, from both genders, within age range of 15-45 years, having pure conductive hearing loss with an Air-Bone gap of not less than 15 dB were selected by convenient sampling technique. Patients having an active ear disease or previous history of ear surgery, an active sinus or URT disease, or any comorbidity were excluded from the study. Complete general and head-neck examination was done after taking history. Patients’ affected ears were examined under surgical microscope to see the drum perforation, condition of middle ear mucosa and the status of the ossicles. Hearing assessment was done by Pure Tone Audiometry through both air and bone conduction. Temporalis fascia graft myringoplasty was done in all these patients by over-underlay technique, and they were discharged on 5th post-operative day, and were followed up in ENT OPD after 3 weeks. Status of graft was seen under surgical microscope after removing the BIPP. After three months the patients were reviewed for graft status and hearing assessment. Successful outcome was taken as those patients in whom graft uptake was successful with complete closure of perforation, and secondly, closure of the Air-Bone gap by at least 10 dB. Data was analyzed by SPSS 19. Results: Mean age of the patients (n = 80) was found to be 30.8 Years. Gender distribution showed 57 (71.25%) Males and 23 (28.75%) Females with a M:F ratio of 2.5:1. Success rate was found significantly better among younger aged males. Graft uptake was successful in 74 (92.5%) of the patients. With respect to closure of A-B gap, post-operative mean difference in Air-Bone gap was found to be 9.6 dB ± 3.9 SD as compared to preoperative mean A-B gap of 28.5 dB ± 4.2 SD, thus a closure of A-B gap by 18.9 dB ± 2.4 SD. Conclusion: Over-underlay technique is found to be a successful technique for myringoplasty in terms of graft uptake and improvement in hearing thresholds in the patients with inactive tubo-tympanic type of CSOM.

Impact of Exchange Rate Threshold Level on Stock Market Performance-Evidence from Ghana
Authors: Awadzie David Mensah
Published: March 2021

Exchange rate plays a vital role in an economy and the purpose of this study is to investigate the impact of exchange rate threshold level on the capital market performance. The study employed a Threshold Autoregressive model introduced by Tong (1978) and Hansen (1996). The study used secondary quarter-time series data for thirty-years from 1990 to 2019. The capital market performance was measured by the value of shares traded; market turnover; market capitalization and all-shares index. However, the results revealed the following estimated threshold level of exchange rate for each performance indicator: 7.94%; 25.33%; 25.33% and 7.80% respectively. In all, the threshold level of the exchange rate estimated was 8 and 25 per cent. The findings suggest that low exchange rate is performance-enhancing. In addition, the exchange rate above the threshold level is detrimental to the capital market performance. The findings of this investigation might be helpful to the government of Ghana and policymakers as they settle on an exchange rate target to adopt to avoid the detrimental effects of high exchange rate while obtaining the growth benefits of the low exchange rate. It has indicated that the exchange rate impacts the economy more than inflation in the Sub Saharan Africa but, not much works in the subject area in Sub Saharan Africa. Therefore, I recommend that more threshold studies have to be carried out on the exchange rate in the other sectors of the economy to ascertain its impact on the economy.

Der Beitrag thematisiert Techniknutzung durch ältere Menschen und widmet sich der Grenzauflösung zwischen Privatheit und Öffentlichkeit im digitalen Zeitalter. Die Auflösung der ehemals getrennten Sphären vollzieht sich vor allem durch Alltagstechnologien. Durch diese gelangen Informationen aus der Privatsphäre automatisch in die öffentliche Sphäre. Diese Daten werden personenbezogen ausgewertet und haben häufig das Ziel, die Lebenswelt der Nutzer zu beeinflussen.25 Eine Mehrheit der über 60-Jährigen in Deutschland nutzt das Smartphone, dessen Einsatz mit einem Kontrollverlust im Hinblick auf die Weitergabe und Nutzung privater Daten einhergeht. Um diesem Kontrollverlust zu begegnen, müssen subjektbezogene Interventionen gefördert werden. Dabei sollten Risiken und Chancen der Auflösung zwischen Privatheit und Öffentlichkeit durch digitale Technologien benannt, reflektiert und abgewogen werden.

The purpose of this paper is to design a microwave monolithic integrated circuit (MMIC) for low noise amplifier (LNA) X-band (7-12 GHz) based on technology of gallium nitride (GaN) high electron mobility transistor (HEMT) with a T-gate, which has 100 nm width, on a silicon (Si) semi-insulating substrate of the OMMIC company. The amplifier is based on common-source transistors with series feedback, which was formed by high-impedance transmission line, and with parallel feedback to match noise figure and power gain. The key characteristics of an LNA are noise figure and gain. However, in this paper, it was decided to design the LNA, which should have a good margin in terms of input and output power. As a result, GaN technology was chosen, which has a higher noise figure compared to other technologies, but eliminates the need for an input power limiter, which in turn significantly increases the overall noise figure. As a result LNA MMIC was developed with the following characteristics: noise figure less than 1.6 dB, small-signal gain more than 20 dB, return loss better than -13 dB and output power more than 19 dBm with 1 dB compression in the range from 7 to 12 GHz in dimensions 2x1.5 mm², which has a supply voltage of 8 V and a current consumption of less than 70 mA. However, it should be said that LNA was only modeled in the AWR DE.

In this paper we analyze and summarize some recently acquired data coupled with the findings of previous geological, geochronological and metallogenic studies on igneous rocks of the Iorokhan gold-bearing complex in the eastern part of the Bureya massif. Four phases, whose rocks are of hypabyssal and subvolcanic intrusive facies, are shown to define the structure of the Iorokhan complex of minor intrusions; characteristic features of their composition and structural and tectonic settings of localization are given; geological and geochronological data are reported on their age (103 ± 1.0–97.4 ± 6.5 Ma), i.e. late Albian–early Cenomanian. By the ratio of alumina, calcium and alkalis, most of their compositions correspond to I-type high-alumina magnesia and magnesia-ferruginous varieties (A/CNK < 1.1) with low concentrations of HFSE, including HREE. Melting of an amphibolitic source rock produced a melt that could be a deep source of the Iorokhan diorites. A brief description of the Noni deposit is given and the main factors contributing to the localization of gold mineralization are considered. The ranges of the Iorokhan magmatites in the East Bureya volcano-plutonic zone can be considered as one of the fragments of the boundary structure between the continental margin of the eastern part of the Bureya massif and the accretionary wedges of the Sikhote-Alin orogenic belt. The Iorokhan complex of minor intrusions is assumed to be a small fragment of the wide belt of Late Albian–Early Cenomanian magmatite occurrence in the southern Far East of Russia, which formed in a setting of transform continental margin and zones of compression associated with extension resulting in the development of pull-apart basins typical of such margins.
Design and Simulation of a controller for Double Fed Induction Generator turbine Utilized Solar Up Draft Tower
Authors: Heelan Mayada Yousif , AL-Qrimili Fadhil Abbas
Published: March 2021

This paper introduces a complete design and simulation of a controller for the double fed induction generator (DFIG) turbine. The work also included the solar updraft tower (SUT) design to supply Al-Mahmoudia hospital in Baghdad/Iraq. The design includes the daily average load estimation, annual solar irradiance and, temperature monitoring, and logging.

According to the data obtained from the Ministry of Science and Technology, Baghdad has low wind speed. Therefore, the (SUT) has been designed to generate electrical power depending on the difference between the external and internal air temperature. The temperature difference will generate a suitable airspeed to drive the wind turbine, connected to the proposed (DFIG) generators that generate the appropriate electrical power required. The proposed controller of the DFIG is based on (vector control) by using PI control to feed the power of the rotor circuit parts. The (DFIG) consists of two back-to-back PWM inverters connected between the stator and the rotor. This paper's main goal is to design and simulate a controller for two (DFIG's) under various operating conditions driven by a wind turbine, which is rotated by the warm wind effect inside the solar updraft tower. This is to generate maximum power with constant magnitude and frequency of the output voltage. The proposed controller's performance is verified by using a simulation model built using the MATLAB/Simulink software. The simulation results confirm that the proposed controller (Vector Control), using PI controller maintains both the magnitude and frequency of the output voltage stays constant at the nominal values and stabilization irrespective of the wind speed variations and extract maximum output power. In addition, the controller provides (MPPT) to the turbine to generate the maximum power according to the available wind speed. The torque will give the rotor quadrature current (Iqr), which causes speed change according to the working conditions. The results also showed the steady-state and discussed the two different methods (Vector Control, MPPT) of the control strategy (DFIG). MATLAB and Simulink software used for modeling one of DFIG's modules to supply the hospital load of 276 KW. Besides, simulation results show that the controller demonstrates significant improvements in terms of better stability and faster response.

Published: March 2021

The precipitation of calcite induced via microorganisms (MICP) is a technique that has been developed as an innovative sustainable ground improvement method utilizing ureolytic bacteria to soil strengthening and stabilization. Locally isolated Bacillus Sonorensis from Iraqi soil samples were found to have high abilities in producing urease. This study aims to use the MICP technique in improving the undrained shear strength of soft clay soil using two native urease producing bacteria that help in the precipitation of calcite to increase the cementation between soil particles. Three concentrations of each of the locally prepared Bacillus sonorensis are used in this study for cementation reagent (0.25M, 0.5M, and 1M) during the period of treatment. The results showed that the native isolated bacteria have high activity in bindings the soil particles together. The results of unconfined compressive strength tests showed that using MICP helps increase the undrained shear strength of soil by (3-5 times) for C11 types of native isolates, but the D11 was (1.5-2 times) because two types have different activity. This study's main finding is using the native urease-producing bacteria isolated from Iraqi soil in the MICP technique for the biocementation of soil, which is considered one of the sustainable techniques in the construction industry.
Gereja Dan Kemiskinan : Diskursus Peran Gereja Di Tengah Kemiskinan
Authors: Santosa Evan Gunawan
Published: March 2021

Gereja dan kemiskinan, permasalahan kemiskinan bukan hanya menjadi masalah lokal namun sudah menjadi tantangan secara global. Gereja sebagai mandataris tuhan di tuntut untuk dapat berperan membatu masalah kemiskinan serta untuk menyuarakan ketidak adilan dan penindasan hak-hak orang miskin. Gereja hadir untuk beropihak kepada yang lemah dantak berdaya, jika gereja tidak berpihak kepada yang lemah maka kehadiranya tidaklah bermakna.
Understanding Clarence Ayres’s criticism to an emerging mainstream and birthing institutionalism through the 1930s Ayres-Knight debate
Authors: Almeida Felipe , Cavalieri Marco
Published: March 2021

Clarence Ayres was a strong dissenting voice in US economics during the 20th century. In the 1930s, a debate between Ayres and Frank Knight was published by the International Journal of Ethics. Although the debate focused on ethics, the evolution of economics was also discussed. This paper proposes an understanding of Ayres’s ideas based on the context in which he made them. This context is defined by the 1930s Ayres-Knight debate and the archival correspondence between Ayres and Knight during the 1930s.
Uniformly Embedding Topological Manifolds into $L^{2}$ Spaces
Authors: Chou Yu-Lin
Published: March 2021

With a simple argument, we show as a main note that every locally compact second-countableHausdorff space is topologically embeddable into some $L^{2}$ space with respect to some finite nonzero Borel measure, where the embedding may be chosen so that it is uniform and its range is included in some open proper subset of the $L^{2}$ space.

Preliminaries on the accurate estimation of the Hurst exponent using time series (Draft 1)
Authors: Millán Ginno
Published: March 2021

This article explores the required amount of time series points from a high-speed computer network to accurately estimate the Hurst exponent. The methodology consists in designing an experiment using estimators that are applied to time series addresses resulting from the capture of high-speed network traffic, followed by addressing the minimum amount of point required to obtain in accurate estimates of the Hurst exponent. The methodology addresses the exhaustive analysis of the Hurst exponent considering bias behaviour, standard deviation, and Mean Squared Error using fractional Gaussian noise signals with stationary increases.
Reassessing Eastern Mediterranean tectonics and earthquake hazard from the AD 365 earthquake

The hallmark of great earthquakes (Mw ≈ 8.3-8.5) in the Mediterranean is the 21 July AD 365 earthquake and tsunami that destroyed cities and killed thousands of people throughout the Eastern Mediterranean. This event is intriguing because most Mediterranean subduction forearcs exhibit pervasive crustal extension and minimal definitive evidence exists for great subduction megathrust earthquakes, consistent with weak seismic coupling. This conundrum has led many to favor rupture of a previously unrecognized upper plate splay fault south of Crete in an Mw 8.3-8.5 earthquake, uplifting a Holocene paleoshoreline on Crete by up to 9 m. Similar source mechanisms have been adapted and commonly used for seismic and tsunami hazard estimation in the region. We present an alternative model for the uplift of the Cretan paleoshoreline and the AD 365 tsunami that centers on known active normal fault systems offshore of western and southwestern Crete. We use new and published radiocarbon dates, together with historical records, to show that uplift of the Cretan paleoshoreline likely occurred during two or more earthquakes within 2 to 3 centuries. Visco-elastic dislocation modeling demonstrates that the rupture of these normal faults fits observed data equally as well as reverse fault models but requires less slip. Tsunami modeling shows that normal-fault ruptures produce strong tsunamis that better match historical reports than a hypothetical reverse fault. Our findings collectively favor the interpretation that damaging earthquakes and tsunamis in the Eastern Mediterranean originate on normal faults and highlight the potential hazard from tsunamigenic upper plate normal fault earthquakes.
Whatever Next and Close to my Self – The Transparent Senses and the ‘Second Skin’: Implications for the Case of Depersonalisation

In his paper ‘Whatever next? Predictive brains, situated agents, and the future of cognitive science’ Andy Clark (2013) seminally proposed that the brain’s job is to predict whatever information is coming ‘next’ on the basis of prior inputs and experiences. Perception fundamentally subserves survival and self-preservation in biological agents such as humans. Survival however crucially depends on rapid and accurate information processing of what is happening in the here and now. Hence the term ‘next’ in Clark’s seminal formulation must include not only the temporal dimension (i.e. what is perceived now); but (ii) also the spatial dimension (i.e. what is perceived here or next-to-my-body). In this paper we propose to focus on perceptual experiences that happen ‘next’, i.e. close-to-my-body. This is because perceptual processing of proximal sensory inputs has a key impact on the organism’s survival. Specifically, we focus on tactile experiences mediated by the skin and what we will call the ‘extended skin’ or ‘second skin’, that is immediate objects/materials that envelop closely our skin, namely clothes. We propose that the skin and tactile experiences are not a mere border separating the self and world. Rather they simultaneously and inherently distinguish and connect the bodily self to its environment. Hence these proximal and pervasive tactile experiences be viewed as a ‘transparent bridge’ intrinsically relating and facilitating exchanges between the self and the physical and social world. We conclude with potential implications of this observation for the case of Depersonalisation Disorder, a condition that makes people feel estranged and detached from their self, body and the world.
Modelowanie przedsiębiorstwa międzynarodowego
Authors: Cieślik Andrzej
Published: March 2021

Neoclassical economics, a dominant framework until the 1970s and 1980s, treated activities of the multinational firms as a part of portfolio theories of international capital flows. The analysis of various kinds of imperfect competition or firm heterogeneity was impossible until the elements of the theory of industrial organization were introduced into the international trade theory. This modification allowed direct inclusion of two basic motivations for establishing multinational firms, horizontal and vertical ones, in the analysis. In this chapter, we present the basic theoretical models that incorporate those two trends (Helpman-Krugman-Markusen models) as well as the imperfect attempts at their integration (the knowledge-capital model) and the most important examples of empirical studies aimed at the verification of their theoretical claims.
Interakcje polityki pieniężnej i fiskalnej a niezależność banku centralnego – przegląd możliwych podejść modelowych w badaniach empirycznych
Authors: Kokoszczyński Ryszard , Mackiewicz-Łyziak Joanna
Published: March 2021

There are numerous theoretical and empirical studies on interactions between monetary and fiscal policy. Even if the independence of central banks affects those interactions, it has rarely been directly included in those studies. In this chapter, we present two general approaches to empirical studies on interactions between those two policies and the possibilities for inclusion of independence of central banks in their modelling. Generally, the first approach has poor theoretic background and relies on simple models describing rules for fiscal and monetary policies. Those models also include proxies for some aspects of fiscal policy. Similarly, some simple measures usually address the independence of central banks. The second approach most often roots in the fiscal theory of the price level. The overwhelming majority of presented studies report a significant impact of the central banks’ independence in the form of a more sustainable policy using the first approach.
