TESTAMENTARY DISPOSITIONS IN THE CONTEXT OF GLOBAL PANDEMIC
Authors: Stilinović Marko
Published: July 2021

The outbreak and the rapid spread of global COVID-19 pandemic have put significant strains on the institutions. The need to adapt to “new normal” and contain the rapid spread of disease, while maintaining a functional society, resulted with introduction of numerous new legal mechanisms and adaptation of the existing ones. However, it seems that one area of law remains on the fringes: the regulation of wills. Even before the start of the pandemic many authors often pointed to the fact that the current legal framework does not follow modern technological developments, but no significant attempts were made to overhaul the inheritance law. Also, once the pandemic started in its full, there were no references to introduction of extraordinary mechanisms or new legal solutions to overcome the potential difficulties in forming wills. Comparative analysis yielded no better results: although some countries (such as Austria) recently completely overhauled their regulation of inheritance law, it seems that no attempts were made to introduce new types of wills or new methods of drafting wills into their regulations. Furthermore, following the spread of the pandemic, increasing number of potential testators find themselves unable to use traditional methods of drafting wills as they, or the authorized persons tasked with assistance and creation of wills, remain isolated from one another due to various reasons (lock-downs, isolation in case of experiencing symptoms, etc.). Having in mind these circumstances, it is necessary to ascertain whether there is a genuine need to introduce new types of wills into existing legal framework, or to adapt the current legal framework by facilitating the communication between citizens and the institutions. Also, it is necessary to analyze whether the interpretation of the existing legal framework enables the introduction of certain facilitating mechanisms. In order to reach these goals and clarify the possibilities within the current legal framework, interpretative and comparative method are used.
STUDENT ATTITUDES TOWARDS MIGRANTS IN THE PRE-COVID-19 PERIOD
Authors: Blagojević Anita , Horvat Gordana
Published: July 2021

There is no doubt that prior to Covid-19 outbreak the issue of migration had been one of the top priorities across the European Union, especially after so-called ‘’refugee crisis’’ of 2015-2017. However, the situation rapidly changed since Covid-19 outbreak, when migration has fallen off the radar as a political issue. The aim of this paper is to analyse students' attitudes towards migrants, in the period before COVID-19, and our initial thesis is that the fact that attitudes towards migrants are rooted in individual values and when established can be resistant to change. The paper consists of three parts. In the first part of the paper, we give an overview of available reports on the impact of Covid-19 to public attitudes towards migrants. Although is too early to make some general conclusions about it, the surveys made so far show that external factors, such as Covid-19, does not make important changes to public attitudes towards migrants. Having this in mind, in the second part of the paper we present the results of our research which was developed as a part of the project ''Creating Welcoming Communities'' of the Association ''MI''. The purpose of this research was to identify the attitudes of students of the Faculty of Law Osijek for the acceptance and integration of migrant into society. The target group of survey participants covered by the research was defined so as to include students of different levels (Intergrated Undergraduate and Graduate Study Programme, Professional Administrative Study Programme, University Undergraduate Study of Social Work) and the sample of students included 300 persons. Finally, in the third part of the paper we give a synthesis of our research and a review of the topic from the perspective of human rights and social work in the community.
THE COVID-19 PANDEMIC AND THE IMPLEMENTATION OF THE EUROPEAN GREEN DEAL
Authors: Carević Melita
Published: July 2021

This paper aims to explore how the COVID-19 pandemic influenced the implementation of the European Green Deal and to which extent have the European Union’s green growth and sustainable development goals been incorporated into its COVID-19 Recovery Strategy. The European Union’s Green Deal, a ‘generation defining’ growth strategy, which lays down the strategic pathway of the European Union’s economic development for the upcoming two decades, has been faced with a major challenge shortly after its adoption in December 2019. However, despite the COVID-19 pandemic, which has continuously been putting all European Union member states to a harsh challenge during the past year, climate change and the green transition have been at the top of the political agenda in the European Union and have managed to occupy the attention of the mainstream politics and European Union citizens. Furthermore, the unprecedented levels of public financing which have been mobilised due to the pandemic have provided an opportunity for speeding up the green transition, without which the achievement of the Green Deal’s main aims and the fulfilment of the European Union’s obligations under the Paris Agreement would likely be put in question. In order to analyse how the has the COVID-19 pandemic influenced the implementation of the Green Deal, the paper first examines how the member states and the European Union institutions initially reacted to the idea of pursuing the implementation of the Green Deal simultaneously with economic recovery. This is accomplished through an analysis of statements given by the European Union and member state officials and the adopted measures and legislative proposals. The paper then focuses on publicly available data on legislative delays in regard to the implementation of the Green Deal which took place due to the pandemic and concludes that no significant postponements occurred. It subsequently turns to examine which measures have been adopted at the European Union level that link the economic recovery and the green transition. In this regard, special attention is paid to the Recovery and Resilience Facility and its measures aimed at ensuring that member states pursue climate change and environmental objectives in their recovery plans. Given the size of the public investments which will take place in the following years, the paper emphasises the importance of stringent environmental standards in order to ensure that they contribute to the green transition and avoid a fossil fuel lock-in.
Tall Poppy Syndrome & Patriarchal Femininity: An Auto-ethnographic Investigation into New Zealand’s Female-identifying Comedians
Authors:   , Hill Katherine
Published: July 2021

This practice-based and auto-ethnographic research project explores the correlation between Tall Poppy Syndrome (TPS) and patriarchal femininity in the performances of female-identifying stand-up comedians in New Zealand. I identify ways TPS, as a patriarchal ideology, has an impact on the subconscious/and or conscious choices of New Zealand’s self-deprecating female-identifying comedians in contemporary performance. I have chosen to analyse TPS through an intersectional feminist lens, focusing on ways the historical construction of patriarchal femininity directly relates to the cultural phenomenon of Tall Poppy Syndrome. I aim to connect this relationship to the ways New Zealand female-identifying comedians ‘perform’ autobiographical comedy, as part of expected social and cultural conventions. As I want to investigate the impact of TPS in an exclusively New Zealand context, my research isolates its case studies to comedians who make comedy primarily for a New Zealand audience, discussing international comedians as a point of comparison.
Visitation frequencies of bumblebees and swallowtail butterflies to flowers and the nectar sugar concentration of Rhododendron kaempferi and R. japonicum in mountains of central Japan
Authors: Takahashi Keigo , Itino Takao
Published: July 2021

Relationships between flower visitor composition and floral traits help us to understand floral evolution. Swallowtail butterflies have been assumed to be the main pollinators of Rhododendron kaempferi and R. japonicum based on their floral shapes, and R. kaempferi was reported to be pollinated by butterflies in southern Japan. In the mountains of central and northern Japan, however, bumblebees are abundant and candidate pollinators of Rhododendron. We found that visitation frequencies of bumblebees were higher than those of swallowtail butterflies to both of the Rhododendron species at three study sites in the mountains of central Japan. R. japonicum pollen adhered to the bodies of both floral visitors. Further, the nectar sugar concentration of R. kaempferi was in the preference range of bumblebees, whereas that of R. japonicum was suited to both bumblebees and butterflies. Taken together, these findings support the hypothesis that bumblebees are potentially also important pollinators of R. kaempferi and R. japonicum in mountains of central Japan, where they are more abundant than swallowtail butterflies.
Testing how antagonistic interactions impact the robustness of plant-pollinator networks

Published: July 2021

Given ongoing pollinator declines, it is important to understand the dynamics of linked extinctions of plants driven by pollinator extinctions. Topological robustness models focused on this question suggest relatively high robustness of plant species to pollinator species extinctions. Still, existing robustness models typically assume that all interactions in plant-pollinator networks are positive, which is clearly not always the case. For example, many pollinators remove floral resources without transferring pollen, or even damage floral structures in the case of nectar robbing. Here we introduce antagonistic interactions into plant-pollinator networks and assess the resilience of plant communities to pollinator species losses. Incorporating antagonistic interactions leads to lower network robustness, i.e. an increased rate of plant species loss (as compared to networks with only mutualistic interactions) in empirical plant-pollinator networks. In conjunction with extinction order, the addition of increasingly antagonistic interactions was idiosyncratic in that it did not always magnify the effects of extinction order across the three networks. These results underscore the importance of considering the full spectrum of interaction outcomes when assessing robustness to coextinctions in plant-pollinator networks, as well as other ecological systems.
Pollinator effectiveness in the mixed-pollination system of a Neotropical Proteaceae, Oreocallis grandiflora
Authors: Cárdenas-Calle Santiago , Cardenas Juan D , Landázuri Boris O , Mogrovejo Gabriela , Crespo Antonio M , Breitbach Nils , Schleuning Matthias , Tinoco Boris A
Published: July 2021

In pollination systems with a diverse community of floral visitors, qualitative and quantitative variations in pollination effectiveness can lead to a system in which higher effectiveness results from the synergetic contribution of multiple pollinators. By employing a series of field and laboratory experiments in the south Andes of Ecuador, we compared the effectiveness of hummingbirds and nocturnal mammals visiting Oreocallis grandiflora, an Andean member of the Proteaceae. Pollinator effectiveness was measured with a quantitative component that assessed visitation rates to inflorescences and number of contacted stigmas per visit, and with a qualitative component that counted the number of deposited pollen grains in stigmas. Effectiveness estimates were complemented with controlled pollination experiments that contrasted fruit and viable seed set among flowers exposed to either diurnal or nocturnal pollination, self-pollinated flowers, and a control group with flowers exposed to naturally occurring pollination. Four species of hummingbirds and two species of nocturnal mammals visited the flowers of O. grandiflora. Hummingbirds outperformed nocturnal mammals in the quantitative components of pollination, while mammals were more effective than hummingbirds in the qualitative component. Pollination success was higher for the control group than for the other treatments, while hummingbirds and mammals performed similarly. Our findings suggest a case of functional complementarity in pollination: hummingbirds’ quantitative effectiveness complements nocturnal mammals’ qualitative effectiveness. Furthermore, our study demonstrates that pollination success in plants can be greater when flowers are visited by the whole diversity of pollinators.

Abstract: Loyalty remains one of the main issues and concerns for researchers and practitioners. The relationship with satisfaction and service quality is evident, but in turn is still insufficient to achieve. This brings us to keep looking for other relationships and not just a behavioral, attitudinal and cognitive stage but from an emotional level and can achieve loyalty in those dimensions. Service encounters where the employee matches with the customer, is the time where they test all organizational intentions and where the customer receivesattention. It is at this point where research has emphasis.Keywords: customers, emotions, service encounters, service loyaltyJEL: M120, M300Resumen: La lealtad sigue siendo uno de los principales temas y preocupaciones para loS investigadores y practicantes.

Sunk Costs Fallacy in Subprime Bubble (Falacia de costos en burbuja de alto riesgo)
Authors: Velázquez Juárez Eduardo
Published: July 2021

Financial Bubbles have been interest of many people, especially in the academic area. It is necessary to understand them with the seriousness that they deserve, due to their potential to cause social, economic and political disruptions. In this paper I talk about the subprime bubble and its general conditions but it is enriched with the contributions of the behavioral finances, specifically with the role of sunk costs fallacy in the behavior of housing mortgagers instead of the stock investors, as it is usual to talk about them in several researches. It is suggested that sunk cost fallacy may provide an additional and important point of view to understand this financial bubble from a parallel market point of view, because this fallacy could be the reason of holding mortgages that eventually became impossible to get paid, which is supported with the fact of relaxation in credit policy and unethical practices of the banks. Finally, they are discussed, the main consequences and chances experienced after the bubble, putting into consideration to explore this behavior with further researches in housing investors.

Steel Beam-Column Joint with Discontinuous Vertical Reinforcing Bars
Authors: Hu Ju-Yun , Hong Won-Kee , Park Seon-Chee , Kim Jisoon
Published: July 2021

The authors proposed steel beam-column connections for precast concrete frames in previous studies. The steel-concrete composite frames provided fast assembly time as steels with economy of concrete structures. However, when enough space is not available at column-beam joints steel sections from beams cannot be connected with column brackets. This paper suggests that some vertical reinforcing bars are disconnected at joints by connecting vertical steel reinforcements to steel plates placed above and below column steels to provide load transferring path. Loads from re-bars are transferred to steel plates, column steels and back to steel plates and re-bars below column steels. Re-bars connected to steel plates by bolts at above and below column steel are discontinued at joint to provide spaces for connections between column brackets and beam steels. Extensive experiments were performed to verify load transfer from re-bars to steel plates above joints and steel plates to re-bars below joint. The flexural load bearing capacity of a column with total of 24 vertical re-bars were compared to columns with discontinuous re-bars at joints. The number of discontinuous re-bars at joint used in column specimen was 0 (0.0%), 4 (16.7%), 12 (50.0%), and 20 (83.3%). The numbers in parenthesis are the percentages of discontinuous rebars to the total number of vertical re-bars of control column. Experiments showed how loads from vertical steel reinforcements that were cut off at joints were transferred to steel plate. The test results also demonstrated that a part of flexural capacities were reduced for specimen with discontinuous vertical re-bars. The reduction of 6.0 %, 13.7% and 54.0% of flexural capacities were observed for columns with 4 (16.7%), 12 (50.0%) and 20 (83.3%) discontinuous vertical rebars, respectively. The test results can be used to design vertical reinforcing bars and column joints that can provide space for column brackets to which steel members of beams are connected.
Development of Novel Connections for Pre-cast Composite and Pre-cast Concrete Frames

Published: July 2021

In some applications, the conventional steel pipe racks were encased with concrete to protect the frame from fire. However, the concrete encasing steel is not considered to contribute to structural capacity at all. This paper proposed pipe rack frames encased by precast concrete, but with functions both as a part of structural elements contributing to flexural load bearing capacity and to fire proofing. The new steel-concrete composite structural system consisting of steel, concrete with reinforcements, extended steel plates with bolts designed based on inelastic finite element method provides efficient structural performances, reducing material quantities with the protection from fires. Additionally extended plate with bolts introduced for column-beam joint assembly played important roles in providing moment connections. AISC 358 introduced the use of extended plate similar to the proposed connection. Significant experimental and analytical investigations were performed to verify structural behaviour of the composite frame. Material quantities were also compared to demonstrate economy of the new frames compared with conventional pipe rack frames.

The industrial chain of building industrialization (BI) has been forming in China during the latest three decades development, which gradually presents a trend of networking. However, the enterprises’ implementations of building industrialization are far from satisfactory. Both practitioners and managers hold the same confusions: Who is controlling effective information resources by occupying critical path in BI network? Who decides the flow direction of materials resources in the network? To solve these doubts, this paper makes an analysis of building industrialization micro social network based on the structural hole theory. A typical industrialized construction project in Shenzhen (China) was selected for the empirical study. Firstly, a questionnaire survey is conducted to collect authentic data and Ucinet is used to delve structural holes by four indicators named effective size, efficiency, constraint and hierarchy. Secondly, the roles and function of stakeholders would be re-explained by the theory of brokerage roles. The outcomes of social network analysis indicate that developer is the information hinge of this BI project due to its largest value of effective size as well as lowest constraint. From the perspective of resource control, contractor and component supplier also occupy critical structural holes and play important roles in building industrialization network. But to some extent, the network of BI in China is not optimized. Thus, enterprises should try to adopt some reasonable accretive measures according to the market condition and self-position.
Robotic Assembly System for Steel Structures

Workers are required to stand on dangerous unfinished steel structures to assemble elements manually. Therefore, we developed a robotic assembly system (RAS) to prevent accidental falls. The RAS consists of four methods: rotation, alignment, bolting, and unloading. The rotation method utilizes a flywheel equipped on top of a rigging beam to rotate the beam. The vertical alignment relies on a camera and a marker to align the altitude of the beam. The horizontal alignment relies on a specially designed shape that can smoothly guide the beam to the right position. The bolting method adds an additional plug hole above each bolt hole to assemble the beam. The unloading method uses pin mechanisms and motors to unload the cable and the RAS. The system is tested in a scaled indoor experiment and the results show that the process is finished without workers stay in the high place. In conclusion, the RAS helps reduce accidental falls, is suitable to the current erection method, and can be broadly introduced to existing sites.

Over the past few decades, modular concrete construction emerged as a viable solution for meeting client requirements in getting an early return on investment, a high quality building, and an economically feasible construction. Precast concrete construction offers several green building benefits such as reducing construction wastes, minimizing site disturbances, and increasing flexibility. Although modular construction has been on the rise in Lebanon, many obstacles stand in the way of reaping more value for customers including technical, logistical, and organizational issues. This research aims at assessing the obstacles for efficient industrialized construction and exploring opportunities for improvement. The study reports results from industry-wide interviews covering all modular precast production companies, the major architects and design professionals, and class-A contracting companies. Findings of the study highlight that technical, logistical, and organizational/ cultural factors form the main obstacles, whereas cost, time, sustainability, and flexibility are the areas of opportunity for implementing efficient industrialized construction and increasing the uptake of precast concrete construction.

Published: July 2021

Workers in certain industries are exposed to high labor-intensive tasks. Low back pain (LBP) is widespread among construction workers (Hildebrandt, 1995) and is extremely prevalent, with every adult having up to an 85% chance of experiencing LBP at least once during his or her lifetime. Back-related complaints are more costly than those from any other body part for Alberta work-related claims. Ergonomic principles in addition to the engineering considerations should be included in the design of work stations to minimize the risk of injury for employees. In this study, we assessed the low back muscle fatigue due to lifting tasks. The objective was to investigate the changes in muscle activity and kinematics of the human body caused by fatigue due to repetitive lifting tasks. Three healthy male volunteers with no recent back complications were asked to complete 3 cycles of lifting task at the Syncrude Centre of the Glenrose Rehabilitation Hospital. Each cycle involved lifting a 15lb window frame for 20 times. Self? adhesive reflective markers were attached on the hands, trunk, and legs to measure displacements and rotation of the body parts while performing the task. Electromyography (EMG) sensors were placed on lower back muscles to record their activity. The muscle fatigue was investigated by studying change in EMG spectral parameters such as RMS, mean frequency (MNF), and median frequency (MDF) as well as physical condition of subjects due to repetitive lifting. The power frequency curve shifted to the low frequency when muscle fatigue occurred. As a result, the slope of the RMS, and MNF indicators were successful to describe the fatigue behavior expected.
Experimental and Numerical Study of Seismic Performance of Precast Prestressed Concrete Frame Internal Connection
Authors: Liao Xiandong , Hu Xiang
Published: July 2021

The seismic performance of the internal connection of precast prestressed concrete frame was studied systematically, based on the experiment of full-scale model under low cyclic reversed loading. This study was mainly focused on failure pattern, load-carrying capacity, skeleton curves, and hysteresis curves. Furthermore, a nonlinear finite element analysis using Abaqus was carried out to study the characteristics of the internal connection of precast prestressed concrete frame. Results revealed that the damage was concentrated mainly on beam end owing to flexural action, while steel bars in the columns and stirrups in the core region remained elastic until failure occurred. The calculated value of the load-carrying capacity of the internal connection was similar to the experimental one. Present study can be referenced for the application of precast prestressed concrete frame in high seismic zones.
