Authors: Mahklouf Mohammed H. 
Published: April 2021

Abstract
This study aims to investigate the coastal plant biodiversity status of Tripoli Province. The result of the survey led to a collection and identification of 130 plant species belonging to 36 families and 105 genera, of which 29 species represented monocotyledons and 101 dicotyledons. Floristic analysis revealed the dominance of the family Asteraceae (24 species) followed by the family Poaceae (22 species). The results have also showed the predominance of the genera Juncus and Lotus with 4 species each. Life form and chorological spectra analyses showed the prevalence of therophytes, represented by 77 species, and the Mediterranean chorotypes with 46 species. Categorization of collected plant species according to their ecological types, revealed a variety of ecological types, with the prevalence of psammophytes, represented by 50 species.

Authors: Akomah Benjamin Boahene , Lawson Roland William , Jackson Emmanuel Nana 
Published: April 2021

Abstract
Labour productivity is key to the success of every construction project. The paper seeks to determine the factors that affect labour productivity and proffer possible ways to improve it in building construction projects. The study was preceded by a literature review. Data used were primary data collected through the use of questionnaires. The total number of respondents was 175. Snowball sampling technique was used in sampling respondents. Factor analysis was performed on the data collected and mean scores were also generated. The findings of the study showed that the use of wrong equipment, misuse of time schedule, lack of training sessions, poor site organisation, lack of motivation for workers, delays in the supply of materials and rework were the critical factors affecting labour productivity in building projects of Ghana. However, the major ways of improving labour productivity in building construction projects, according to the study, were to correct bad behaviour that negatively influenced productivity, proper layout of site, to improve health and safety, to use proper materials handling systems and to set targets for employees. Management must put structures in place to restrict human, material and construction related factors. This is because giving concessions in these areas can take a toll on productivity.
Sensitivity of Real Estate Investment Return to Market Return Index: The Case of Nigerian Real Estate Investment Trusts
Authors: Adilieme Chibuikem , Umeh Obinna 
Published: April 2021

Abstract
The level of sensitivity of every investment option to a market index is crucial to investors. Sensitivity analysis of individual or a set of returns on investments to market return index predicts the reaction of the investment(s) to changes in the market index; informs investors of prospective performance of different investments types; as well as assists the investors in making appropriate decisions on investment selections. This paper assessed how sensitive indirect real estate investments in Nigeria were to market index. The three companies whose asset returns were considered in this study were real estate investment trusts listed in the Nigerian Stock Exchange. The data used in this study were sourced from annual reports of the listed companies, and reports of the Nigerian Stock Exchange. The beta coefficients were used to determine the sensitivity of the selected stocks to market return index. The study found a very low and insignificant beta coefficient among various real estate investments and market return index. Hence, there is no relationship between the market return index and the returns on the Real Estate Investment Trusts listed in the Nigerian Stock Exchange.

Authors: Bello Musa Zango , Sanni Mohammed Lekan , Mohammed Jibrin Katun 
Published: April 2021

Abstract
Housing market analysis has witnessed considerable changes in recent decades, especially as a result of the complexity of human settlements and the dynamics of property market analytical techniques. This paper reviews various techniques/methods adopted by researchers and housing experts in analysing the housing market in recent times. The present study is a literature review and, therefore, essentially relies on published data sourced from academic journals, conference papers, thesis, and other secondary sources. The paper highlights the methods considered appropriate and relevant for different property market scenarios, especially in developing countries. The paper, therefore, recommends what it regards as the most appropriate basis for a housing market analysis and research in developing countries against the backdrop of the dynamics of the property market.
Motivations and livelihood dynamics in the urban informal economy: the case of Dire Dawa City, Eastern Ethiopia
Authors: Dube Engida Esayas 
Published: April 2021

Abstract
This article assesses the motivations for participation in the informal economy in general and street vending in particular and explores vendors’ livelihood dynamics in Dire Dawa city, Eastern Ethiopia. Data were collected from fixed and itinerant vendors who were found vending a variety of goods and services in the city during data collection. A descriptive survey design was employed in this study. Time location sampling procedure – a new method of two-stage sampling that has been widely used to select the hard-to-reach segment of society – was employed to select 198 street vendors. Data were collected using a questionnaire survey, in-depth interviews and observation during 2016/17. The study revealed that the majority of vendors report that they engaged in street vending for survival. But some consider it is an opportunity for income, employment and growth, and livelihood improvement in the city. The majority of vendors indicated that there have been improvements in their lives since they started vending. Thus, this study points to the need to employ multiple perspectives to capture the reality underneath livelihoods in the informal economy. Policy approaches that recognise the vitality of public spaces for street vending activities, the integrality of vendors to the socio-economic fabric of the city, and their modest contributions to the socio-economic development of the city are necessary.
The impact on urban accessibility conditions of a proposed cableway line in the city of Manizales, Colombia
Authors: Montoya Jorge Alberto , Aguilera Juan Camilo , Escobar Diego Alexander 
Published: April 2021

Abstract
Due to the increased tendency to use private transport in urban areas of Manizales and Villamaría municipalities, it is intended to include alternative modes of transport that are more time-efficient and environmentally sustainable to improve the inhabitants’ quality of life. This article aims to analyse the inclusion impact of a sustainable public transport system, such as a new cableway line in the city connecting the Central Business District (CBD) with Ciudadela del Norte district, measuring overall average accessibility for the current and future scenario. This establishes the average travel time and the savings in terms of time shown as a percentage that these modes of transport would create in the population displacement and also which inhabitants are the most likely to benefit.
Multivariate classification of provinces of Vietnam according to the level of sustainable development
Authors: Truong Van Canh 
Published: April 2021

Abstract
The research aims to classify the level of sustainability of 63 provinces in Vietnam upon 24 indicators reflecting three main dimensions of sustainable development by using multivariate classification method for the year 2014–2016. First of all, the principal component analysis (PCA) was applied to group quantitative variables that reflect important aspects of each component of sustainable development of localities in Vietnam into a number of limited dimensions (factors). The results of PCA illustrate 8 principal components in which 3 main components of economic and social pillar, and 2 main components for environmental pillar. After that, the second method was applied by using the hierarchical methods of cluster analysis for the set of 8 principal components conducted by PCA. With the candidate solution divided all of the provinces into 6 clusters, the analysis shows that the higher level of sustainable development belongs to South East, Red River Delta, and North Central, in which 4 provinces of South East (Ho Chi Minh City, Binh Duong, Dong Nai, and Ba Ria – Vung Tau) form a group with the highest level of sustainability. The regions such as South Central Coastal, Highland area, and Mekong River Delta have the medium level; the North midland and mountain areas are regions at the low level of sustainability.
Faţete Ale Feminităţii În Dramaturgia Blagiană – (De) Limitări
Authors: Frătean Denisa-Maria 
Published: April 2021

Abstract
The aim of this paper is to identify the way in which Blaga’s feminine characters deconstruct the canon of feminity imposed at the time. This deconstruction is based on the theory of performative gender imposed by Judith Butler, who emphasized the fact that gender is not innate, but rather constructed. In the second part of the essay, in the form of an ecocritical approach, we proved the idea that there is a tight connection between women and nature on the one hand and natural disasters and patriarchy on the other hand.
Update of Internal Political Threats to the National Security of Ukraine at the Local Level in the Process of Administrative and Territorial Reform
Authors: Hulai Vasyl 
Published: April 2021

Abstract
The article presents theoretical and practical aspects of political and legal instruments aimed at minimizing the risk of intra-Ukrainian political character. The priority in the implementation of administrative and territorial reform in Ukraine should be the implementation of the interests of local communities, and not the administrative, political and economic priorities of local elites. It should be emphasized that the territorial organization of Ukraine as a mandatory, indispensable element of the general organization of the state is considered mainly as part of the formed social structure and as a division of the country’s territory into certain parts. It is necessary to take into account the historical and legal nature of the tasks and functions of the state, as well as the organization of the system of state authorities and local self-governments.
Distribution and numbers of waterbird species breeding in the city of Wrocław
Authors: Kopij Grzegorz 
Published: April 2021

Abstract
During the years 2003-2010, the numbers of pairs of waterbird species breeding in the city of Wrocław (293 km2) were assessed. The city is situated in Odra valley, where four smaller rivers join it. The city abandons in oxbows, gravel and sand, and clay pits and other water bodies. In total, 20 waterbird species were recorded as breeding in Wrocław. The most common were Anas platyrhynchos (145-212 pairs), and Fulica atra (70-104 pairs). Relatively common were also the Gallinula chloropus (28-37 pairs), Rallus aquaticus (9-25 pairs) and Cygnus olor (9-11 pairs). For each remaining species less than 10 pairs were recorded. Among rare species, the following were recorded as breeding in Wrocław: Grus grus, Mergus merganser, and Porzana porzana. In the few recent decades, the increase in the number of breeding pairs was recorded for Anas platyrhynchos and Cygnus olor; while a parallel decrease was recorded for Fulica atra, Gallunula chloropus, Chroicocephalus ridibudnus, and Tachybaptus ruficollis. Species such as the Aythya fuligula, Aythya ferrina, grebes, gulls and terns avoid the city. Some of them even ceased to breed (Anas quarquedula, Anas clypeata and Botaurus stellaris). The city plays an important role in protecting water bird species such as Grus grus, Cygnus olor, Porzana porzana and Alcedo atthis.
Fostering University Students’ Idea Generation and Idea Evaluation Skills With a Cognitive-Based Creativity Training
Authors: van Broekhoven Kim , Belfi Barbara , Hocking Ian , van der Velden Rolf 
Published: April 2021

Abstract
This paper examines the effectiveness of a 10-hour cognitive-based creativity training on idea generation and idea evaluation among 51 undergraduate students (mean age 22) from a large university in the Netherlands. A pre-post-test within-subject design was conducted. All 51 students received the training as part of their bachelor program, and were assigned to receive the training in the first or second semester. As such, students participated in both experimental conditions (control and intervention), albeit at different times (within-subject design). The Alternative Uses Task (AUT) and specially designed idea evaluation tasks were used before and after the training. In the idea evaluation task, students were asked to evaluate ideas on their originality and feasibility. Their ratings were compared with content experts’ ratings. General Linear Models (GLM) for repeated measures were conducted to determine whether any change in idea generation and idea evaluation is the result of the interaction between type of treatment (i.e. intervention or control group) and time (pre- and post-test). The results indicated that students did not generate significantly more (i.e. fluency) and different kind of ideas (i.e. flexibility) after training. Most importantly, in line with recent research, the results suggested that training does not impact idea evaluation skills among students. This suggests that idea evaluation might be a more complex process to enhance than idea generation. The implications of these results for educational practice and future research are discussed.
Creative Individuals are Social Risk-takers: Relationships between Creativity, Social Risk-Taking and Fear of Negative Evaluations
Authors: Bonetto Eric , Pichot Nicolas , Pavani Jean-Baptiste , Adam-Troïan Jaïs 
Published: April 2021

Abstract
If the importance of social psychological factors in creativity has been widely emphasized, research across the social sciences mainly focused on identifying contextual factors that increase or decrease individuals’ creative behaviors. Few studies have investigated the relationships between creativity and individual characteristics related to interpersonal and social interactions. The present contribution aimed to consider such characteristics, namely social risk-taking (i.e., willingness to challenge norms) and fear of negative evaluation (i.e., apprehension about receiving negative judgments of others). Two correlational studies were therefore implemented in order to clarify previous research suggesting that creativity would be positively associated with social risk-taking and to extend them by testing potential associations between creativity and fear of negative evaluation. Using self-ratings of creativity, but also creative self-beliefs and creative achievement, we hypothesized that creativity would correlate positively with social risk likelihood and negatively with fear of negative evaluation. As predicted, and replicating previous results, all our measures of creativity correlated positively with social risk-taking. Our results also consistently highlighted a negative association between beliefs in one’s creative capacities (creative self-efficacy) and one’s level of fear of negative evaluation. These findings corroborate the idea according to which creative individuals would be (social) risk-takers. In addition, individuals who are confident in their ability to generate creative productions would be less afraid of negative judgments from others. Several perspectives are proposed, in particular in terms of the intervention designed in order to enhance individuals’ creativity.
Giving the Art Greater weight in Art Psychology: RizbA, a Questionnaire for Formal Picture Analysis
Authors: Schoch Kerstin , Ostermann Thomas 
Published: April 2021

Abstract
In empirical art psychology and creativity research most studies focus on the psychological correlates of art. Only few go beyond treating artworks as categorical data (e.g. abstract vs. representational) and consider artworks in detail. In part this is due to the lack of reliable quantitative measurements. The rating instrument for two-dimensional pictorial works (RizbA) makes a difference to current research designs. The current study validates the questionnaire on a representative sample of contemporary visual art, consisting of 318 images depicting works by artists from different cultural areas dated to the 21st century. In a randomized test-retest design, the pictorial material was rated by 506 (T1) and 238 (T2) art experts using RizbA. Statistical quality criteria, such as item difficulty, capacity of differentiation, test-retest reliability, and intraclass correlation were calculated. Principal component analysis (PCA) and indices of factor similarity were computed. The overall test’s capacity for differentiation yields partial eta-squared of .31 (T1) and .40 (T2). Test-retest reliability is .86. PCA reveals an eight-factor solution, which is largely consistent across both measurement points. Tucker’s coefficient of congruence ranges between |.71| and |1.00|. Intraclass correlation coefficients are .86 (T1) and .73 (T2). This study indicates generalizability of the questionnaire to contemporary artworks. Although a conclusion on the factors’ structure cannot be drawn yet, results are very promising. As the first reliable quantitative tool for formal picture analysis, RizbA allows more detailedexamination of visual art and its psychological correlates. This broadens research methodology by giving art greater weight in art psychology and creativity research.
Blame and Fault: Toward a New Conative Theory of Blame
Authors: Bernáth László 
Published: April 2021

Abstract
This paper outlines a new conative theory of blame. I argue that the best-known conative approaches to blame (Scanlon 1998, 2008, Sher 2006a) misrepresent the cognitive and dispositional components of blame. Section 1 argues, against Scanlon and Sher, that blaming involves the judgment that an act or state is the fault of the blamed. I also propose an alternative dispositional condition on which blaming only occurs if it matters to the blamer whether the blamed gets the punishment that she deserves. In Section 2, I discuss objections to judgment-based accounts of blame (that they cannot tell the difference between blaming and judging to be blameworthy, that they cannot explain why blame is often accompanied by emotion, and that they cannot make sense of irrational blame), and I argue that my proposal can handle all of them.
Mural Paintings of Ixmiquilpan. Barbarism and Civilization
Authors: Brenišínová Monika 
Published: April 2021

Abstract
This paper deals with the 16th century mural paintings that cover the walls of the parish church of San Miguel Arcángel, a former Augustinian mission in Ixmiquilpan. The paintings represent warriors in battle and mixing the Western iconography with the prehispanic one. They are associated with the Chichimeca War (1540-1590), a conflict that threatened the existence of the Viceroyalty of New Spain (1535-1821). The article examines the images of “otherness” and related stereotypes conceiving the paintings as a place, where the identity of local inhabitants was discussed and putting particular emphasis on the pair of categories – barbarism and civilization. In terms of method, it is interdisciplinary and interpretative. It combines the classical historical, art historical concepts and methods with terms and procedures of anthropology and social science.
An Empirical Study on Environmental Efficiency Measurements and Influencing Factors

Published: April 2021

Abstract
Airlines are an important part of the comprehensive transportation system. Therefore, it is of great practical significance to empirically analyse the measurement of airlines’ environmental efficiency and influencing factors. Adopting the SBM-DEA model, this study measured the environmental efficiency of 20 Chinese airlines between 2010 and 2017 and empirically analysed the factors influencing their environmental efficiency using a Tobit regression model. Spring Airlines, China Southern Airlines, and Hainan Airlines were found to have the highest environmental efficiency. Tianjin Airlines, Hebei Airlines, and China Express Airlines had the lowest environmental efficiency. The Tobit regression results showed that average flight distance, load factor, market share, and proportion of cargo and mail turnover had a significant positive effect on airline environmental efficiency. Fuel consumption per ton-km had a significant negative effect on airline environmental efficiency.
Seasonal Dynamics of Catalase Activity in Cystoseira crinita (Black Sea) and Fucus vesiculosus (Barents Sea)
Authors: Shakhmatova Olga , Ryzhik Inna 
Published: April 2021

Abstract
The seasonal dynamics of catalase activity of two related species of brown macroalgae, Cystoseira crinita (Desf.) Bory (1832) and Fucus vesiculosus L. (1753) was studied. In general, catalase activity (CA) in C. crinita was several times higher than in F. vesiculosus. The maximum values of CA in C. crinita were observed in November and the minimum ones in September. For F. vesiculosus, the maximum CA was found in January and the minimum in April. Abrupt changes in water temperature significantly affected the catalase activity in C. crinita and F. vesiculosus. In both species of algae, a similar seasonal trend in the change of CA was noted: two periods of adaptation adjustment associated with sharp changes in the temperature regime (spring and autumn) were distinguished. In spring, with a rapid increase in the temperature of the water masses, catalase inactivation occurred, whereas during summer to winter transition, accompanied by a sharp water cooling, catalase activity increases. Stabilization of the CA values of the studied macroalgae in the absence of sharp temperature variability was observed. However, this period of “stationary state” varies in time: in Cystoseira crinita it lasts from May to August, and in Fucus vesiculosus it lasts from May to December.
