Published: January 2021

Utilization of mangrove seeds is not as popular the use of wood tree. Utilization of wood from mangrove tree is used as raw material for making charcoal and building materials.The local community rarely uses mangrove seeds for food, drinks, scrubs and coloring. This is not enough of public knowledge about the benefits of mangrove seeds. The public mindset that the only sources of carbohydrates are rice and corn. There is not much knowledge about the potential and benefits of mangrove seeds as a coffee drink. The research method used in this research is experimental research. In this experiment, 3 repetitions of treatment and 3 replications. Water content data in the mangrove seed ground coffee was tested by normality test. The proximate test results show ash content of 1 to 4% when averaged is 2.6%. While the general requirement for roasted coffee (SNI.01.2983-1992) is 7-14% ash content. The color of coffee is influenced by the value of the extract content of the coffee, water soluble coffee juice will give it a deep black color ( Pastiniasih, 2012). The juice content of magrove coffee is high enough for each treatment so that the steeping gives a visually visible black color.

The components of coral reef ecosystem can be described by the unique regulation in community level. Coral reef fishes use coral reef as their habitat and they highly depend on coral reef health. Otherwise, the condition of coral reef health can be predicted by the biodiversity of coral reef fishes. The research aim was describe communities differences between two explored area in marine tourism spots in Pahawang Island. This research was conducted on November 2019 at two stations on the coral reefs ecosystem of Pahawang Island represented the two quitely different area, the marine tourism and the visitor areas. The coral reef fishes were observed by using visual census method with a Line Transect length of 30 meters and a visibility of 2.5 meters left and right of the transect. Coral reef fish community structure was measured by diversity, similarity, and dominancy indexes. A total of 1.940 coral reef fish species from 13 families were recorded. Pomacentridae is the most speciose family (1.091 species), followed by Siganidae (308 species) and Labridae (166 species). Biodiversity of coral reef fishes at Pahawang Island showed results diversity index (H') in both observation stations classified as medium with a low dominance index value (C) and similarity index (E) at both stations classified as high, presumably as a result of tourism activities. The diversity index at station 2 has a greater value than station 1 as a tourist area with diving and snorkeling tourism activities, at station 2 there are more types or genus of reef fish, compared to station 1.

Authors: Ndung’u Francis Kamau 
Published: January 2021

This study aimed at establishing the effect of demographic characteristics on employment in Sub Saharan Africa. The study used data ranging from the year 1990 to the year 2015 that was obtained from the data banks of World Bank and FAOSTAT. The panel data that was obtained and used was for 30 Sub-Saharan African Countries. The traditional Neo classical production function was utilized in this study in estimating the regression results. Hausman test was carried out and it determined that fixed effects estimations were preferred to random effects and as a consequence, random effects estimations were made use of during the analysis of data. In establishing the relationship between demographic characteristics and employment, demographic characteristics, imports and services sectors variables were found to statistically and significantly influence employment. However, domestic capital was found to negatively influence employment though this was not statistically significant, while exports was found negatively and statistically significantly influencing employment.
Reflections on post-bailout policy analysis in Ireland
Authors: Murphy Mary , Hogan John 
Published: January 2021

Abstract
This short article reflects on observations from the forthcoming volume Policy Analysis in Ireland, edited by Hogan & Murphy. The volume forms part of the International Library of Policy Analysis series, which covers more than twenty countries, published by Policy Press and edited by Michael Howlett and Iris Geva-May. While various themes emerge from the Irish volume, this article focuses on only one core question: whether and how the 2008 economic crisis contracted and expanded the capacity for policy analysis in Ireland. The troika of the International Monetary Fund, European Central Bank and the European Commission are associated with policy capacity innovation, but also with significant austerity. Both had a major and long-term impact on public services. While the article documents a range of successful post-bailout attempts to improve policy analysis capacity, it also points to often less conscious, but sometimes deliberate, decisions that diminished some forms of policy analysis capacity. We find economic policymaking capacity enhanced while changes to resources and policy opportunity structures depleted both space and the capacity for social policy analysis. This was particularly so within the equality and social justice sectors. Given ongoing social risks, the Covid-19 pandemic and the climate crisis, Ireland needs to adjust for a future of permanent uncertainty, or perpetual crises, and should seek to rebalance investment in social policy capacity and to develop systems for integrated policy analysis.

Published: January 2021

Abstract
There are several thousand different cultivars of apple trees but only a limited number are cultivated on an industrial scale. Old cultivars can be useful, for example, in the processing industry due to their different composition. In many cases, they have higher organic acid content. The content of mineral components, colour, and polyphenols in the fruit of 7 old apple tree cultivars, growing in the Wolinski National Park, was studied. The changes that occurred in the fruit after freeze-drying were also evaluated. The trees from which the fruit was picked for analysis, despite the lack of chemical protection, were fruiting and the apples had only a few symptoms of damage caused by pests or diseases. The fruit was characterised by a high soluble solids content (14.4-16.4%), in which sugars and especially fructose dominated. The number of organic acids varied greatly and ranged from 0.27 (Oberlander Himbeerapfel) g to 1.07 g/100 g (Winter Goldparmane). The content of polyphenols in fresh apples ranged from 186 mg (Horneburger Pfannkuchenapfel) to 354 mg/100 g (Winter Goldparmane) and increased after freeze-drying from 666 mg (Weisser Winterkalvill) to 1486 mg/100 g (Winter Goldparmane). The dominant group of polyphenolic compounds was phenolic acid. The freeze-drying process caused unfavourable changes in the colour of the pulp. The fruits of Oberlander Himbeerapfel cultivar were most susceptible to these changes. However, the least darkened fruit of Horneburger Pfannkuchenapfel.
Analysing flood history and simulating the nature of future floods using Gumbel method and Log-Pearson Type III: the case of the Mayurakshi River Basin, India
Authors: Islam Aznarul , Sarkar Biplab 
Published: January 2021

AbstractFloods of the Mayurakshi River Basin (MRB) have been historically documented since 1860. The high magnitude, low-frequency flood events have drastically changed to low magnitude, high-frequency flood events in the post-dam period, especially after the 1950s, when the major civil structures (Massanjore dam, Tilpara barrage, Brahmani barrage, Deucha barrage, and Bakreshwar weir) were constructed in the MRB. The present study intends to find out the nature of flood frequency using the extreme value method of Gumbel and Log-Pearson type III (LP-III). The results show that the highest flood magnitude (11,327 m3s−1) was observed during 1957–2009 for the Tilpara barrage with a return probability of 1.85% and the lowest (708 m3s−1) recorded by the Bakreshwar weir during 1956–77 with a return probability of 4.55%. In the present endeavour, we have computed the predicted discharge for the different return periods, like 2, 5, 10, 25, 50,100, and 200 years. The quantile-quantile plot shows that the expected discharge calculated using LP-III is more normally distributed than that of Gumbel. Moreover, Kolmogorov–Smirnov (KS) test, Anderson–Darling (AD), and x2 distribution show that LP-III distribution is more normally distributed than the Gumbel at 0.01 significance level, implying its greater reliability and acceptance in the flood simulation of the MRB.
Constructing non-orthogonal split-split-plot designs using some resolvable block designs
Authors: Mejza Iwona , Ambroży-Deręgowska Katarzyna , Ozawa Kazuhiro , Mejza Stanisław , Kuriki Shinji 
Published: January 2021

Summary
We consider a new method of constructing non-orthogonal (incomplete) split-split-plot designs (SSPDs) for three (A, B, C) factor experiments. The final design is generated by some resolvable incomplete block design (for the factor A) and by square lattice designs for factors B and C using a modified Kronecker product of those designs (incidence matrices). Statistical properties of the constructed designs are investigated under a randomized-derived linear model. This model is strictly connected with a four-step randomization of units (blocks, whole plots, subplots, sub-subplots inside each block). The final SSPD has orthogonal block structure (OBS) and satisfies the general balance (GB) property. The statistical analysis of experiments performed in the SSPD is based on the analysis of variance often used for multistratum experiments. We characterize the SSPD with respect to the stratum efficiency factors for the basic estimable treatment contrasts. The structures of the vectors defining treatment contrasts are also given.

Authors: Alonso Gema Cárdenas , Masot Ana Nieto 
Published: January 2021

Abstract
The LAGs (Local Action Groups) are in charge of designing the development strategy under the LEADER Approach for their areas of action, as well as managing European aid for Rural Development in order to promote new economic activities with which generate progress and alleviate the demographic and socioeconomic problems of its most depressed municipalities. Thus, in this paper the qualitative analysis of LEADER in Extremadura (SW Spain) in the 2007–2013 programming period is presented through the results of a questionnaire to the technical staffs of the 24 LAGs in order to complement the various previous quantitative studies and to know the opinion of essential actors in the rural development processes. During the 2007–2013 period (with the EAFRD as European Fund to finance rural development aids) LAGs have faced great bureaucratic and administrative burdens, which adds to the difficult economic situation experienced in recent years. This has hindered the true labor of these partnerships, that is, to revitalize their territories of action in order to create socioeconomic and, consequently, demographic development.
A Technical Efficiency Analysis of Financial Subsidies Allocated by the Cap in Romanian Farms Using Stochastic Frontier Analysis
Authors: Galluzzo Nicola 
Published: January 2021

Abstract
The Common Agricultural Policy (CAP) has undergone radical changes as a consequence of international agreements. Through a parametric approach based on Stochastic Frontier Analysis, it has been possible to estimate the impact of financial subsidies allocated under the Common Agricultural Policy for the period from 2007 to 2017 in the framework of the first and second pillars to Romanian farms that are part of the FADN dataset. The findings have revealed the positive effect of financial subsidies allocated to disadvantaged rural areas in increasing technical efficiency, and a modest impact of decoupled payments disbursed under the first pillar of the CAP on the Romanian farms investigated.

The paper also includes recommendations for managers and entrepreneurs on what should be considered in order to survive in today's competitive and global marketplace. The authors present the level of awareness of the entrepreneurs in the area of business models and the response to these results in the form of micro-learning. This involves a compendium on business models and bite-sized modules directed towards adult educators in management, start-ups, managers, and entrepreneurs. The insights provided are expected to be valuable to researchers and practitioners interested in the topic of business models.
Low-power latch comparator with accurate hysteresis control
Authors: Khanfir Leïla , Mouïne Jaouhar 
Published: January 2021

Abstract
Recent research has focused on finding ways to control hysteresis of dynamic comparators. The current proposed techniques are based on either geometrical dimension adjustment or digital control. The first case does not allow for post fabrication control, while the second has limited accuracy. This paper presents a new dynamic comparator design with external hysteresis adjustment using an analog voltage. This is achieved by proposing an architecture including control devices with a specific sizing. This is performed with no significant increase of the design complexity, keeping the power consumption as low as possible. The design is analyzed, showing that the proposed solution allows accurate hysteresis adjustment without affecting the inherent circuit properties. The dynamic comparator is also implemented using a 180 nm commercially available CMOS technology. The results show that a variation of 550 mV of the control voltage allows an accurate hysteresis adjustment ranging from 0 to 40 mV, according to the input conditions. Moreover, the simplicity of the circuit in conjunction with the use of dynamic technology have allowed the best performances to be achieved compared to the current state of the art, in terms of energy with an FoM equal to 116 fJ/decision and silicon area of 180 µm2 .
Global Language Politics: Eurasia versus the Rest
Authors: Kamusella Tomasz 
Published: January 2021

Abstract
Globalization in the early 21st century can be considered as the age of inequality that splits the world into the rich North and the poor South. From the perspective of language politics, only very few discussed the division across the globe, especially, between Eurasia and the “Rest of the world.” In Eurasia, indigenous languages and scripts are used in official capacity, while the same function is fulfilled almost exclusively by non-indigenous (post/colonial) European languages in the Rest of the world. In the countries where they are spoken, non-Eurasian languages have limited presence in the mass media, education, or in cyberspace. This linguistic imperialism par excellence is a long-lasting and pernicious legacy of European (western) colonialism. The aforementioned divide is strongly associated to the use of ethnolinguistic nationalism in state building across many areas of Eurasia, while this ideology is not employed for this purpose outside the region.
Motivations of Young Consumers to Participate to Collaborative Consumption
Authors: Puiu Andreea-Ionela 
Published: January 2021

Abstract
Collaborative consumption is currently an exciting topic of interest for many debates and controversies being perceived as a fast-growing social phenomenon. Considering the contemporary development processes via sharing economy, there is an interest to prove that the segment of young consumers practices changed from traditional buying and owning behaviour to collaborative consumption stratagems. Thus, the central objective of the present study is to explore the potential young consumer behaviour adjustments and to discuss the motivations behind those changes by considering the emergence of collaborative consumption.
The primary hypothesis of the present article states that intrinsic and extrinsic motivations influence teenager’s attitudes and behavioural intentions regarding participation in collaborative consumption.
Regarding the methodology, the author’s performed confirmatory factor analysis and structural equation modelling. The objective was to determine if previously exposed motivational factors influence positively the young consumer’s behavioural intention and their attitude towards a supposed adherence to collaborative consumption schemes.

Authors: Junlai Li , Yonghe Xie , Weiguo Wu , Chi Zhang 
Published: January 2021

Abstract
Floating wind power platforms are in constant motion due to waves when deployed at sea. This motion directly affects the stability and safety of the platform. Therefore, it is very important to study the laws governing the platform’s dynamic response. In this paper, the dynamic characteristics of an offshore floating wind power platform were analysed under nine different sets of operating conditions using a numerical calculation method. Following this, a scaled 1:50 platform model was tested in a tank. Model tests were carried out with different wave conditions, and dynamic response data for the platform were measured and analysed. The hydrodynamic variation rules of floating wind power generation platform in waves were obtained. Some effective measures for maintain the stability and safety of wind power platforms are put forward that can provide a reference for dynamic stability research and the design of floating wind power platforms in the future.
Automatic Control of Ship Motion Conducting Search in Open Waters
Authors: Kula Krzysztof Stefan 
Published: January 2021

Abstract
In this work a search operation support system is presented, which is an additional autopilot function block. Its task is to lead a vessel included in the search by the SAR services to the datum position on the basis of the data entered by the operator into the system and then automatically to search the indicated area according to the newly defined search pattern. The set goal can be achieved thanks to the autopilot that guides the ship along a given trajectory consisting of straight lines and arcs. High control accuracy is provided by the IMC control system using a relatively simple non-linear ship model. The simulation tests of the tanker model confirmed that the indicated search area can be precisely checked in a shorter time than when using the expanding square search pattern.

Published: January 2021

Abstract

Background
Radiotherapy-associated angiosarcoma (RAA) of the breast is a rare complication of radiotherapy, which is often difficult to identify and has poor prognosis. It usually presents as violaceous skin, erythema or rapidly growing palpable firm mass that can be confused with other benign skin lesions.

Patients and methods
After reviewing the literature, we found only four cases with RAA after mastectomy and autologous breast reconstruction. The presented case is the first that was treated by electrochemotherapy. The patient presented with secondary angiosarcoma of the breast five years after mastectomy, immediate breast reconstruction with deep inferior epigastric artery perforator free flap and adjuvant radiotherapy.

Results
Electrochemotherapy was feasible, safe and effective in treatment of radiation induced sarcoma. Most of the treated lesions in several consecutive electrochemotherapy sessions responded with complete response, but multiple recurrences occurred in non-treated areas.

Conclusions
Patients with breast cancer after skin-sparing mastectomy and immediate breast reconstruction, who receive radiotherapy, need regular long-term follow up and low threshold for biopsy of any suspicious lesions is mandatory. Electrochemotherapy proved as one of feasible modalities of treatment for RAA.
