Change is a pre-requisite for survival amongst individual human beings and even more so in the organizations which they create and in which they work. Put simply, if an organization does not change what it offers the world – its product or services- and the ways in which it creates and delivers these offerings, it may not survive. The pressure for a constant innovation means that creativity is a key resource. Innovation, technology advances and competitive advantage are connected by complex and multidimensional relationships. Demands for organizational innovation and technological advantage are increasingly crucial components of competitive strategy for many firms. Most firms face serious competitive challenges due to the rapid pace and unpredictability of technology change. Industries dependent on highly sophisticated technologies and firms engaged in multinational competition are particularly vulnerable to the need for continuous and rapid modification of their product features and the ways in which they conduct business.
THE ROLE, POSITION AND CERTIFICATION OF MANAGEMENT ACCOUNTANTS
Authors: Petrović Teodor M.
Published: June 2021

There are many questions about the role of accountants in the age of globalization, the greatest achievement and growing international mobility of capital, commodities, ideas and people. The role of a management accountant has become significant, not only at the corporate level but also nationally and internationally. His position has primarily undergone metamorphosis from a numerical reporter to a senior information decision support specialist, business management partner, internal consultant, organizational educator, etc. The certification of management accountants stems from the understanding and the need for this responsible profession to be of a licensed nature associated with very high educational and professional requirements in countries with advanced accounting. The certification of accountants and auditors is envisaged in Bosnia and Herzegovina, while there is currently no specific certification for a certified management accountant. The accounting profession has developed its ethical standards, which have been adopted in Bosnia and Herzegovina, and also apply to management accountants. However, the specific role of management accounting has led to the codification of the Standards of Ethical Conduct for Management Accountants by professional organizations. The aim of the paper was to investigate the role and place of management accountants, their challenges and public perceptions, as well as the certification and ethical standards for management accountants in countries with advanced accounting and in Bosnia and Herzegovina. The results showed that the situation in countries with advanced accounting and in Bosnia and Herzegovina is significantly different, and Bosnia and Herzegovina must improve the guidelines it relies on, take on the practices of others who have made significant progress in this area, and to set goals to pursue.

Published: June 2021

Промене у платним системима појединих земаља инициране употребом криптовалуте, отвориле су бројне дилеме у економској литератури. Иако се сазнања о овом феномену још увек нису довољно искристалисала, поједине државе регулисале су његову употребу. У овом раду истражујемо да ли се криптовалуте могу сматрати валутом, што је скренуло све већу пажњу регулатора забринутих за порез, осигурање и друге последице које се везују за законски третман криптовалуте. Предмет рада је да анализара историју, карактеирстике и степен регулације криптовалуте у свету. Циљ рада је да, кроз анализу држава, у којима је употреба криптовалуте легална, истражи могућности за регулацијом крипотовалуте у Републици Србији.

Published: June 2021

Много је питања у вези са улогом рачуновођа у ери глобализације, највеће достигнуте и растуће међународне покретљивости капитала, роба идеја и људи. Улога управљачког рачуновође је постала значајна, не само на корпоративном, већ и на националном нивоу, па и на међународном нивоу. Његово мјесто је превасходно претрпјело метаморфозу од припремача бројчаних извјештаја до високог специјалисте информационе подршке одлукама, пословног партнера менаџмента, интерног консултанта, организационог едукатора и сл. Сертификовање управљачких рачуновођа проистиче из схватања и потребе да то, одговорно занимање, буде лиценцног карактера повезано са врло високим образовним и стручним захтјевима у земљама развијенијег рачуноводства. У Босни и Херцеговини је предвиђено сертификовање рачуновођа и ревизора, док посебног сертификата за овлашћеног управљачког рачуновођу за сада нема. Рачуноводствена професија је развила своје етичке стандарде који су преузети и у Босни и Херцеговини, а који важе и за управљачке рачуновође. Међутим, специфична улога управљачког рачуноводства доводи до кодификације Стандарда етичког понашања за управљачке рачуновође од стране професионалних организација. Циљ рада је био да се истражи улога и мјесто управљачких рачуновођа, њихови изазови и перцепције јавности, као и сертификовање и етички стандарди за управљачке рачуновође у земљама развијеног рачуноводства и у Босни и Херцеговини. Резултати су показали да се стање у земљама напредног рачуноводства и у Босни и Херцеговини, значајно разликује, те је неопходно да Босна и Херцеговина унаприједи смјернице на које се ослања, преузме праксе других који су у тој области остварили значајан напредак и одреди циљеве којима треба да тежи.

Collagens are a primary component of the extracellular matrix and are functional ligands for the inhibitory immune receptor leukocyte-associated immunoglobulin-like receptor (LAIR)-1. LAIR-2 is a secreted protein that can act as a decoy receptor by binding collagen with higher affinity than LAIR-1. We propose that collagens promote immune evasion by interacting with LAIR-1 expressed on immune cells, and that LAIR-2 releases LAIR-1-mediated immune suppression. Analysis of public human datasets shows that collagens, LAIR-1 and LAIR-2 have unique and overlapping associations with survival in certain tumors. We designed a dimeric LAIR-2 with a functional IgG1 Fc tail, NC410, and showed that NC410 increases human T cell expansion and effector function in vivo in a mouse xenogeneic-graft versus-host disease model. In humanized mouse tumor models, NC410 reduces tumor growth that is dependent on T cells. Immunohistochemical analysis of human tumors shows that NC410 binds to collagen-rich areas where LAIR-1+ immune cells are localized. Our findings show that NC410 might be a novel strategy for cancer immunotherapy for immune-excluded tumors.
Preserved sensory processing but hampered conflict detection when stimulus input is task-irrelevant

Conflict detection in sensory input is central to adaptive human behavior. Perhaps unsurprisingly, past research has shown that conflict may even be detected in the absence of conflict awareness, suggesting that conflict detection is an automatic process that does not require attention. To test the possibility of conflict processing in the absence of attention, we manipulated task relevance and response overlap of potentially conflicting stimulus features across six behavioral tasks. Multivariate analyses on human electroencephalographic data revealed neural signatures of conflict only when at least one feature of a conflicting stimulus was attended, regardless of whether that feature was part of the conflict, or overlaps with the response. In contrast, neural signatures of basic sensory processes were present even when a stimulus was completely unattended. These data reveal an attentional bottleneck at the level of objects, suggesting that object-based attention is a prerequisite for cognitive control operations involved in conflict detection.
Denouncing the use of field-specific effect size distributions to inform magnitude
Authors: Panzarella Emily , Beribisky Nataly , Cribbie Robert A.
Published: June 2021

An effect size (ES) provides valuable information regarding the magnitude of effects, with the interpretation of magnitude being the most important. Interpreting ES magnitude requires combining information from the numerical ES value and the context of the research. However, many researchers adopt popular benchmarks such as those proposed by Cohen. More recently, researchers have proposed interpreting ES magnitude relative to the distribution of observed ESs in a specific field, creating unique benchmarks for declaring effects small, medium or large. However, there is no valid rationale whatsoever for this approach. This study was carried out in two parts: (1) We identified articles that proposed the use of field-specific ES distributions to interpret magnitude (primary articles); and (2) We identified articles that cited the primary articles and classified them by year and publication type. The first type consisted of methodological papers. The second type included articles that interpreted ES magnitude using the approach proposed in the primary articles. There has been a steady increase in the number of methodological and substantial articles discussing or adopting the approach of interpreting ES magnitude by considering the distribution of observed ES in that field, even though the approach is devoid of a theoretical framework. It is hoped that this research will restrict the practice of interpreting ES magnitude relative to the distribution of ES values in a field and instead encourage researchers to interpret such by considering the specific context of the study.

Rice is the world’s largest food crop, and its production needs to be doubled by 2050 to cope with population growth and associated demand. In addition to the value of improving yields, quality is also important for breeders and consumers, but it pays less attention in arid regions. During two successive summer growing seasons, the experimental material focused on 34 genotypes developed from different crosses on Fn generation after fixation as well as six of the most recent commercial cultivars used for comparisons. The results showed that a high yield of grain followed by high milling and grain quality characteristics were observed among the 34 genotypes used in this analysis. Highly important and positive correlations between the percentage of hulling and the percentage of milling (0.424) and the yield ability could be accomplished by choosing the number of panicles per plant and the weight of the panicles. Selection criteria for good quality should be met by the percentage of head rice and many mineral elements, particularly zinc and iron. As a consequence, the genotypes M.J 5460S/SK105-1, M.J 5460S/GZ7768-1, M.J 5460S/G177-1, M.J 5460S/SK105-3 and M.J 5460S/SK106-4 had desirable high yield and quality characteristics and could be used as promising accessions to the rice breeding program in arid regions. In addition to commercial genotypes, improved Japonica rice genotypes could be produced in arid conditions for higher yield and quality, leading to an increase in total production, supporting food security and nutrition.

Published: June 2021

Background

Cyclocarya paliurus (Batal.) Iljinskaja is a common endemic tree species and used as a Chinese medicine. The main active components in the leaves of this plant are polysaccharides. However, the temporal patterns of gene expression underlying the synthesis of polysaccharides in C. paliurus at different leaf developmental stages and its relationship with the polysaccharide content and antioxidant activities has not been reported to date.

Methods

RNA-seq was used to investigate the biosynthesis pathway of polysaccharides at the four developmental stages of C. paliurus leaves. The content and the antioxidant activities of polysaccharides were measured with typical biochemical methods and the identified correlations were statistically evaluated.

Results

Sixty-nine differentially expressed genes were found in the leaves during different developmental stages of C. paliurus. These are associated with glycosyltransferases and belong to 18 families. During different developmental stages of C. paliurus, the polysaccharide content first increased and then decreased, and the UDP-glucose 4-epimerase gene was found to be significantly positively correlated with the polysaccharide content. The clearance rates of DPPH radicals, superoxide anion radicals, hydroxyl radicals, and the reducing power of polysaccharides in the leaves of C. paliurus at different developmental stages showed a dose-dependent relationship with the concentration of polysaccharides.

Conclusions

The smallest fully expanded leaves are suitable for high-quality tea, and leaves with sizes below the largest fully expanded leaves are suitable for industrial production of polysaccharides.

Published: June 2021

Natural flow regimes play important roles in maintaining the ecological integrity and diversity of aquatic ecosystems. Wildlife has adapted over time to the natural dynamics of their environment, including changes in flow regimes. Changes in flow, including changes in magnitude, frequency, duration, timing and rate of change, may affect the physical characteristics of aquatic habitats, access to habitats, food availability, population dynamics and community composition.

Given the importance of natural flow regimes for fish, it is necessary to understand the extent to which natural flow regimes alter fish abundance and diversity. Here we present a protocol for a systematic review that will estimate how fish abundance and diversity are affected by natural variation (resulting from climatic variability and broad‐scale drivers such as climate‐induced change) in flow.

This systematic review will use evidence published before 2016 that was identified in a recent systematic mapping exercise on the broader topic of flow regime change impacts (both natural and anthropogenic) on direct outcomes of freshwater or estuarine fish productivity. An updated English language search will be performed using six bibliographic databases, Google Scholar and networking tools to include commercially published and grey literature that has been published after 2016. Eligibility screening will be conducted at two stages: title and abstract, and full‐text. We will include all studies that evaluate the effect of natural changes in flow magnitude on fish abundance (broadly defined to also capture density and biomass metrics) and species diversity (broadly defined to also capture species richness and composition metrics). Any freshwater or estuarine fish species in temperate regions will be considered.

Included eligible studies will be assessed for study validity. We will extract information on study characteristics, intervention/comparator details, measured outcomes and effect modifiers. A narrative synthesis will describe the quantity and characteristics of the available evidence, and where sufficient numbers of similar studies are available, a meta‐analysis will be conducted to estimate an overall mean and variance of effect.
Pyrrolidone and Caprolactam Functionalized Natural and Synthetic Polymers
Authors: Brush Kelly A. , Musa Osama M.
Published: June 2021

This chapter provides a sampling of diverse synthetic approaches to pyrrolidone‐ and caprolactam‐functionalized natural and synthetic polymers. Enhancing the property profiles of major industrial polymers is a common motivation for such research endeavors. A significant portion of synthetic polymers are obtained by conventional free radical polymerization of vinyl monomers. Free radical polymerization termination can occur by combination or disproportionation reactions. The class of N‐vinylpyrrolidone polymers is utilized in a wide range of industrial applications. The class of polyvinylcaprolactam polymers are temperature‐responsive materials that have proven useful in many application areas. Polysaccharides are high molecular weight polymeric carbohydrate molecules that consist of long chains of monosaccharide units. Natural biopolymers are available from renewable marine and agricultural resources. Cellulose, chitin, starch, glycogen, and galactomannans are a few examples of common natural polysaccharides. Traditional derivatization of polysaccharides of high industrial relevance, such as cellulose, involves etherification and esterification processes.

Among the bacterial infections that impair the health status of marine mammals, those caused by Brucella spp. are the most reported worldwide. Brucella infections in marine mammals can result in acute or chronic disease and are associated with variable clinical outcomes, depending on the organ involved during the infectious process, infection route, host immunity, and strain pathogenicity. Asymptomatic infections may also occur. The current study expands the investigation of Brucella infection in northeast Brazil by analyzing 19 dead, stranded cetaceans and 52 Antillean manatees Trichechus manatus manatus. The manatees included 8 dead, captive manatees and 44 live specimens, of which 10 were analyzed only after reintroduction into the wild as part of a rehabilitation program, 9 were analyzed both while in captivity or semi-captivity and after reintroduction, 20 were sampled only in captivity or semi-captivity, and 5 were free-living manatees. Serological tests were used to screen for antibodies against smooth Brucella spp. Whole blood, swabs, and tissue samples were screened for Brucella spp. DNA by PCR. Samples with positive PCR results were cultured for Brucella spp. isolation. All manatees yielded negative results in serological and molecular tests. Brucella spp. DNA was detected in the kidney of one adult Guiana dolphin Sotalia guianensis exhibiting necrosis in the liver. No growth of Brucella spp. was observed via microbiological culturing. This study is the first report of Brucella spp. DNA detection in cetaceans in the state of Pernambuco, and it highlights the importance of conducting systematic monitoring for the presence of Brucella infection in marine mammals along the Brazilian coast, especially in the northeast region, where several cases have been reported.

All domains of life utilize a diverse set of modified ribonucleotides that can impact the sequence, structure, function, stability, and the fate of RNAs, as well as their interactions with other molecules. Today, more than 160 different RNA modifications are known that decorate the RNA at the 5′‐terminus or internal RNA positions. The boost of next‐generation sequencing technologies sets the foundation to identify and study the functional role of RNA modifications. The recent advances in the field of RNA modifications reveal a novel regulatory layer between RNA modifications and proteins, which is central to developing a novel concept called “epitranscriptomics.” The majority of RNA modifications studies focus on the eukaryotic epitranscriptome. In contrast, RNA modifications in prokaryotes are poorly characterized. This review outlines the current knowledge of the prokaryotic epitranscriptome focusing on mRNA modifications. Here, it is described that several internal and 5′‐terminal RNA modifications either present or likely present in prokaryotic mRNA. Thereby, the individual techniques to identify these epitranscriptomic modifications, their writers, readers and erasers, and their proposed functions are explored. Besides that, still unanswered questions in the field of prokaryotic epitranscriptomics are pointed out, and its future perspectives in the dawn of next‐generation sequencing technologies are outlined.

Near‐infrared (NIR) organic‐light emitting devices (OLEDs) with high radiance are useful for applications including invisible marking, communication, and biomedical imaging. However, performances of NIR OLEDs are typically limited by their severe efficiency roll‐offs at high current density. Herein, three isoquinolinyl azolate based Os(II) complexes (Isq‐1–3) with short radiative decay lifetime (in hundreds of ns), and photoluminescence with peak wavelengths > 745 nm and quantum yield up to 48% as doped thin films, are reported. Upon concomitant employment of exciplex‐forming co‐host (tris(4‐carbazoyl‐9‐ylphenyl)amine and 2,4,6‐tris(biphenyl‐3‐yl)‐1,3,5‐triazine), efficiency roll‐off is greatly reduced, giving external quantum efficiency of 9.66% at a current density of 300 mA cm−2. A maximum radiance over 170 W sr−1 m−2 is also achieved in devices based on Isq‐2 and Isq‐3.

Nanofibrillar structures are of importance in biomedicine, including lung, cardiovascular, liver, skin, neuroscience research, and tissue engineering. Developing advanced materials and interfaces should contribute to uncovering the mechanisms of diseases aiming to find cure. The similarity between the extracellular matrix (ECM) of soft tissue and hydrogels, characterized by a high water‐content viscoelastic polymeric fiber, has stimulated the development of hydrogels for biomedical applications. However, most hydrogels have a meshy structure resulting in poor cell adhesion properties. Here, fabrication of gellan gum (GG) hydrogels arranged by thermally driven self‐assembly into a network of nanofibers is reported. Mechanical properties of such nanofibrillar hydrogels are analyzed on micro‐ and macroscales. As a result, and in sharp contrast to commonly produced meshy GG hydrogels, the nanofiber‐based hydrogels facilitate the adherence and lead to proliferation of cells. This is assigned to microstructural rearrangements characterized by a changing density and pore size decrease, accompanied with a lower water content. Cell growth on such nanofibrillar structures is investigated for osteoblasts, which are chosen as a model system. The developed nanofibrous interfaces in this study are envisioned to be applicable for growing various types of cells and they should contribute to better understanding cell interactions with ECM.

Published: June 2021

Surface lattice resonances appear in periodic plasmonic nanoparticle arrays due to the hybridization of plasmonic and photonic modes. Compared to localized surface plasmon resonances of single particles, these coupled modes feature reduced linewidth, angle‐dependent dispersion, and long‐range collectivity. Here, the optical response of self‐assembled plasmonic monolayers of periodically arranged gold and silver nanoparticles is studied. In comparison to already established hexagonal lattices, self‐templated honeycomb and Moiré type lattices as well as their binary counterparts that include silver and gold nanoparticles in the same monolayer are looked at. All periodic arrays feature macroscopic dimensions (cm‐scale) and support surface lattice resonances as evidenced from classical extinction measurements. The experimental findings are supported by results from finite difference time domain simulations. Variation of the plasmonic material, the lattice spacing, and geometry enables spectral tunability of the optical response of the lattices.

Quasi‐2D perovskite exhibits excellent luminescence properties for highly efficient perovskite light‐emitting diodes (PeLEDs). However, the lattice degradation and crystalline phase transition induced by water limit the PeLED's development for application and commercialization. It is demonstrated that the organic additives effectively reduce the defect density, while the bonding strength of these organics and perovskite becomes weak under the high electric field and the Joule heat in an operating PeLED. Thus, an alternative additive for forming strong bonding with perovskite is promising to improve the stability of perovskite film and PeLEDs simultaneously. Here, it is shown that octylammonium sulfate decoration effectively enhances the moisture durability of PEA2(CsPbBr3)4PbBr4 quasi‐2D perovskite film by generating PbSO4 on the surface. The strong bonding interaction of SO42− and Pb2+ ions leads to the reduced defect density, enhanced lattice stability, and robust photoluminescence quantum yield of perovskite film, which is confirmed by the density functional theory calculation. Moreover, the generated PbSO4 reduces the internal resistance and adjusts the band structure of perovskite film to enhance the carrier transport and injection balance. The PeLEDs based on PbSO4 decorated perovskite film exhibit enhanced operational lifetime and the maximum external quantum efficiency of 10.84%.

Hermite–Gaussian (HG) beams, corresponding to high‐order transverse modes, reveal a great potential in the space division multiplexing in optical and wireless communications. Higher data rates are made possible by the introduction of multiplexing, which is critical for next‐generation wireless communications working at terahertz frequency. Here, the multifunctional all‐dielectric metasurfaces are studied both theoretically and experimentally to implement terahertz mode and polarization division multiplexing. Terahertz incidence with fundamental Gaussian mode could be converted to high‐order HG modes by the silicon‐based metasurface. More interestingly, phase distributions of the axicons and deflectors are integrated into the mode conversion to reduce the divergence of the output beam and spatially separate each mode. The proposed multifunctional metasurfaces open a new avenue to the potential application of metasurface‐based devices in terahertz communication systems.

Inorganic halid perovskites, such as CsPbX3 (X = Br, Cl, or I), have attracted a great deal of attention for next generation on‐chip optoelectronic devices for which high quality thin films are essential. So far, most utilized fabrication techniques for halide perovskite films have been based on solution synthesized methods, taking advantage of cost effectiveness and flexibility. Conventional solution processed thin films suffer from pinholes, poor morphology and/or low mole fraction when embedded in glass or polymer matrixes, unavoidably limiting their application‐level. Herein, we report the fabrication of high crystalline and coverage CsPbBr3 thin films by using a single‐step physical technique – pulsed laser deposition (PLD). As‐fabricated thin films demonstrate stimulated emission with low pump threshold at room temperature. Systematic investigations suggest that the mechanism of stimulated emission in our CsPbBr3 thin films originates from exciton−exciton inelastic scattering. These results not only shed light on high performance all‐inorganic CsPbBr3 perovskite films for various optoelectronic devices, but also enrich the comprehension of stimulated emission mechanism of all‐inorganic CsPbBr3 perovskite materials.

Ferroelectric photo‐thermochromic (PTC) materials with both high coloration contrast and high transparency have attracted great attention for their applications in “smart window” for non‐contact optical information storage. Nevertheless, it has been challenging to develop a ferroelectric PTC material that simultaneously meets the distinct transparency and coloration contrast requirements. Herein, dual rare‐earth ions doping of 1%Er‐(K0.5Na0.5)0.985La0.015NbO6(Er‐KNLN) ferroelectric ceramics is aimed at increasing the optical transmittance and obtaining an ideal coloration contrast. The traditional solid‐state reaction is exploited for ceramics fabrication, and the optimal optical transmittance (≈70% at 900 nm) can be obtained due to finer grains, more symmetrical structure, and compact structure in samples sintered at a suitable temperature (such as ≤1165 °C). Contributed from the trapping and de‐trapping of charge carriers in vacancy‐related defects, the Er‐KNLN ceramics exhibit obvious PTC behavior and the novel impedance modulation is developed. The coupling between PTC behavior and optical transparency, lanthanide up‐conversion emission, patterned display, and room temperature impedance enables nondestructive rewritable and readout characteristics of multi‐mode “0” and “1” states. This work solves the main problems hampering the promising applications of ferroelectric materials and paves a way for developing multifunctional optical memory smart windows.
