Body shape and fin size in juvenile Atlantic salmon (Salmo salar): effects of temperature during embryogenesis
Authors: Greenberg Larry , Jonsson Bror , Norrgård Johnny R. , Erlandsson Ann , Bergman Eva
Published: May 2021

Temperature during egg incubation and early development influences later life stages of fishes, potentially influencing survival. Throughout its distribution, Atlantic salmon (Salmo salar Linnaeus, 1758) have experienced population declines, and in view of ongoing global warming, we tested if temperature during the earliest developmental stages modified body shape and fin size when temperatures averaged 2.6 vs. 5.6 °C. This temperature difference simulates increases predicted in climate change scenarios. Based on previous studies, we hypothesized that salmon originating from eggs subjected to cold incubation temperatures would have slimmer bodies and larger pectoral and dorsal fins than salmon from eggs that experienced warmer temperatures. After hatching, the juveniles were raised for 1 year under identical temperatures, after which we measured their body shape and fin areas. We found no support for our hypothesis regarding body shape. Indeed, we found the opposite, with cold-incubated salmon having deeper bodies than warm-incubated salmon. For fin size, the pectoral fins of cold-incubated salmon were larger than for warm-incubated salmon as predicted, but there was no difference in dorsal fin size. These results suggest that global warming may lead to altered body shape and fin size, possibly affecting swimming performance, and thus raise questions about the ecological consequences of the changes.
Thermodynamic properties of the trigonometric Rosen–Morse potential and applications to a quantum gas of mesons
Authors: Brzo Aram Bahroz , Alvarez-Castillo David
Published: May 2021

In this study, we work out thermodynamic functions for a quantum gas of mesons described as color-electric charge dipoles. They refer to a particular parametrization of the trigonometric Rosen–Morse potential which allows to transform it to a perturbation of free quantum motion on the three-dimensional hypersphere, [Formula: see text], a manifold that can host only charge-neutral systems, the charge dipoles being the configuration of the minimal number of constituents. To the amount charge neutrality manifests itself as an important aspect of the color confinement in the theory of strong interaction, the Quantum Chromodynamics, we expect our findings to be of interest to the evaluation of temperature phenomena in the physics of hadrons and in particular in a quantum gas of color charge dipoles as are the mesons. The results are illustrated for [Formula: see text] and [Formula: see text] mesons.
Assessment of the relativistic rotational transformations
Authors: Kipreos Edward T. , Balachandran Riju S.
Published: May 2021

Rotational transformations describe relativistic effects in rotating frames. There are four major kinematic rotational transformations: the Langevin metric; Post transformation; Franklin transformation; and the rotational form of the absolute Lorentz transformation. The four transformations exhibit different combinations of relativistic effects and simultaneity frameworks, and generate different predictions for relativistic phenomena. Here, the predictions of the four rotational transformations are compared with recent optical data that has sufficient resolution to distinguish the transformations. We show that the rotational absolute Lorentz transformation matches diverse relativistic optical and non-optical rotational data. These include experimental observations of length contraction, directional time dilation, anisotropic one-way speed of light, isotropic two-way speed of light, and the conventional Sagnac effect. In contrast, the other three transformations do not match the full range of rotating-frame relativistic observations.
CPT-violating z = 3 Horava–Lifshitz QED and generation of the Carroll–Field–Jackiw term
Authors: Mariz T. , Martinez R. , Nascimento J. R. , Petrov A. Yu.
Published: May 2021

We study the new extension of the [Formula: see text] Horava–Lifshitz QED involving a CPT-breaking term, characterized by the axial vector [Formula: see text], and calculate the Carroll–Field–Jackiw (CFJ) term in the one-loop approximation. Explicitly, we use two regularization schemes and demonstrate that in our case, the CFJ term is finite but ambiguous, so that its exact coefficient depends on the used regularization.

The role of representation theory in terms of tensor categories is emphasized. Connections to two-dimensional conformal field theory are also presented. In particular, we discuss anyon condensation, gapped domain walls and matrix product operators in terms of operator algebras.
Fabrication of strong macrofibers from plant fiber bundles
Authors: Nakagaito Antonio Norio , Takagi Hitoshi , Katsumoto Yusuke
Published: May 2021

The production of long cellulose macrofibers starting from nanofibers is still complex and expensive. This study proposes a method of manufacturing long macrofibers from plant fiber bundles by chemically extracting non-cellulosic substances but preserving the original shape of the fibers. Once the cellulosic fiber bundles are dried, the original cellulose nanofibers are bridged to neighboring nanofibers by the formation of hydrogen bonds, giving shape stability and enhanced mechanical properties. By the process, the tensile strength was increased by about 50% and the modulus doubled from the original plant fiber bundles.
Magnetic anisotropic colloids in nematic liquid crystals: Fluctuating dynamics simulated by multi-particle collision dynamics
Authors: Armendáriz José , Híjar Humberto
Published: May 2021

Elongated colloids with a permanent magnetic moment and immersed in a nematic liquid crystal are studied numerically using a mesoscopic scheme that supports fluctuations, hydrodynamics, and topological defects. Colloids are accompanied by disclinations curves and subjected to an effective torque caused by the nematic environment and to a magnetic torque due to an external magnetic field. The case is analyzed where these torques compete to bring colloids to two different mutually perpendicular equilibrium states. The fluctuating dynamics of the colloid-defect pair is studied in terms of orientational correlation functions. Analytical expressions for these correlations are derived on the basis of an approximated planar lineal model. A good agreement is found between the numerical and analytical methods when magnetic torques are much larger than nematic torques, while for smaller magnetic torques nonlinear effects are demonstrated to be important. As conclusion, the numerical technique could be considered a reliable approach to the rotational motion of polar nanoparticles in liquid crystals.
Global existence and large time behavior of strong solutions to the nonhomogeneous heat conducting magnetohydrodynamic equations with large initial data and vacuum
Authors: Zhong Xin
Published: May 2021

We investigate an initial boundary value problem of two-dimensional nonhomogeneous heat conducting magnetohydrodynamic equations. We prove that there exists a unique global strong solution. Moreover, we also obtain the large time decay rates of the solution. Note that the initial data can be arbitrarily large and the initial density allows vacuum states. Our method relies upon the delicate energy estimates and Desjardins’ interpolation inequality (B. Desjardins, Regularity results for two-dimensional flows of multiphase viscous fluids, Arch. Rational Mech. Anal. 137(2) (1997) 135–158).
Learning gene regulatory networks using gaussian process emulator and graphical LASSO
Authors: Chatrabgoun H. , Soltanian A. R. , Mahjub H. , Bahreini F.
Published: May 2021

Large amounts of research efforts have been focused on learning gene regulatory networks (GRNs) based on gene expression data to understand the functional basis of a living organism. Under the assumption that the joint distribution of the gene expressions of interest is a multivariate normal distribution, such networks can be constructed by assessing the nonzero elements of the inverse covariance matrix, the so-called precision matrix or concentration matrix. This may not reflect the true connectivity between genes by considering just pairwise linear correlations. To relax this limitative constraint, we employ Gaussian process (GP) model which is well known as computationally efficient non-parametric Bayesian machine learning technique. GPs are among a class of methods known as kernel machines which can be used to approximate complex problems by tuning their hyperparameters. In fact, GP creates the ability to use the capacity and potential of different kernels in constructing precision matrix and GRNs. In this paper, in the first step, we choose the GP with appropriate kernel to learn the considered GRNs from the observed genetic data, and then we estimate kernel hyperparameters using rule-of-thumb technique. Using these hyperparameters, we can also control the degree of sparseness in the precision matrix. Then we obtain kernel-based precision matrix similar to GLASSO to construct kernel-based GRN. The findings of our research are used to construct GRNs with high performance, for different species of Drosophila fly rather than simply using the assumption of multivariate normal distribution, and the GPs, despite the use of the kernels capacity, have a much better performance than the multivariate Gaussian distribution assumption.
Ququats as superposition of coherent states and their application in quantum information processing
Authors: Mishra Manoj K. , Prakash Hari , Jha Vibhuti B.
Published: May 2021

Superposition of optical coherent states (SCS) [Formula: see text], possessing opposite phases, plays an important role as qubits in quantum information processing tasks like quantum computation, teleportation, key distribution, etc. and are of fundamental importance in testing quantum mechanics. Passage of such SCS from a 50:50 beam splitter leads to generation of entangled coherent states. Recently, ququats and qutrits defined in four- and three-dimensional Hilbert space, respectively, have attracted much attention as they offer advantage in secure quantum communication. However, practical utilization of these advantages essentially requires physical realization of quantum optical ququats and qutrits.

Here, we define four new multi-photonic states (MPS) with [Formula: see text] (here, [Formula: see text] or 3 and [Formula: see text]) numbers of photon and show how the SCS can be used to encode ququat using these MPS as basis vectors of a four-dimensional Hilbert space. When these MPS fall upon a 50:50 beam splitter, the resulting states are bipartite four-component entangled coherent states (BFECS) equivalently representing the entangled ququats. We briefly discuss the photon statistical properties of such MPS and BFECS. We show that these MPS and BFECS can be synthesized using even coherent states as input to an interferometer. We give a simple linear optical protocol for almost perfect teleportation of a ququat encoded in SCS with the aid of BFECS as quantum channel. We also describe how these ququats can be used for realization of higher-dimensional BB84 protocol to increase the security of quantum key distribution. Finally, we discuss the possible advantages of using SCS as ququats and BFECS as quantum channel in different quantum information processing tasks.

Semigroups of an inductive composition of terms
Authors: Kitpratyakul Pongsakorn , Pibaljommee Bundit
Published: May 2021

The set of all [Formula: see text]-ary terms of type [Formula: see text] together with a binary operation derived from a superposition [Formula: see text] forms various forms of semigroups. One may generalize such binary operation by deriving it from an inductive composition of terms and call it an inductive product. However, this operation is not associative on the same base set but it becomes associative when all elements of subterms of a fixed term used in an inductive product except itself are excluded from the base set. Hence, a semigroup is formed. In this paper, we mainly focus on the algebraic structures of this semigroup such as idempotent elements, elements associating with each type of regularity condition, and Green’s relations. The formulae of complexity of inducted terms are also under investigation.
Distance Laplacian spectra of joined union of graphs
Authors: Paul Somnath
Published: May 2021

The distance Laplacian matrix of a simple connected graph [Formula: see text] is defined as [Formula: see text], where [Formula: see text] is the distance matrix of [Formula: see text] and [Formula: see text] is the diagonal matrix whose main diagonal entries are the vertex transmissions in [Formula: see text] In this paper, we determine the distance Laplacian spectra of the graphs obtained by generalization of the join and lexicographic product of graphs (namely joined union). It is shown that the distance Laplacian spectra of these graphs not only depend on the distance Laplacian spectra of the participating graphs but also depend on the spectrum of another matrix of vertex-weighted Laplacian kind (analogous to the definition given by Chung and Langlands [A combinatorial Laplacian with vertex weights, J. Combin. Theory Ser. A 75 (1996) 316–327]).
Enhancement of Power by “Box-Car” Transmission Profile in Superlattice Magnetic Tunnel Junctions
Authors: Daqiq Reza
Published: May 2021

Thermoelectric properties of superlattice magnetic tunnel junctions (SL-MTJs) comprising of MgO barriers, ZnO quantum wells and CoFeB contacts are investigated in the linear and nonlinear response regime. The transmission function is calculated by the nonequilibrium Green’s function (NEGF) formalism. The anti-reflective (AR) regions idea in SL-MTJs leads to an enhancement in power factor as well as output power due to the presence of “box-car” transmission in AR-MTJs. Therefore, it can be proposed as a new way to progress in the field of spincaloritronics.

Authors: CHEN Nan , ZHUANG Guiyang , ZHU Shouxian , WANG Dong , LI Jue
Published: May 2021

This paper evaluates the low-carbon development of 176 Chinese cities in 2018 using the Low-carbon City Evaluation Indicator System developed by Research Institute for Eco-civilization, Chinese Academy of Social Sciences. The evaluation shows an overall improvement of low-carbon development of cities in China, with 10 cities scoring 90 points and above, and 106 cities scoring 80–89 points. From the perspective of city category, the low-carbon development scores present an order as follows: service-oriented [Formula: see text]-prioritized [Formula: see text] cities. Geologically speaking, eastern cites perform best, western cities come second and central cities come last. Of the three batches of low-carbon city pilots, the scores follow the pattern of Batch [Formula: see text] 3. Most cities are characterized by high carbon consumption and reduced efforts in low-carbon management and capital investment. Finally, this paper proposes to attach more importance to low-carbon development and strengthen capacity building for low-carbon governance; intensify efforts for constructing low-carbon pilots in order to help achieve the goal of carbon emission peak during the “14th Five-Year Plan” period; and to improve the Low-carbon City Evaluation Indicator System.
If A.I. Only Had a Heart: Why Artificial Intelligence Research Needs to Take Emotions More Seriously
Authors: Merriam Garret
Published: May 2021

Artificial Emotional Intelligence research has focused on emotions in a limited “black box” sense, concerned only with emotions as ‘inputs/outputs’ for the system, disregarding the processes and structures that constitute the emotion itself. We’re teaching machines to act as if they can feel emotions without the capacity to actually feel emotions.

Serous moral and social problems will arise if we stick with the black box approach. As A.I.’s become more integrated with our lives, humans will require more than mere emulation of emotion; we’ll need them to have ‘the real thing.’ Moral psychology suggests emotions are necessary for moral reasoning and moral behavior. Socially, the role of ‘affective computing’ foreshadows the intimate ways humans will expect emotional reciprocity from their machines.

Three objections are considered and responded to: (1) it’s not possible, (2) not necessary, and (3) too dangerous to give machines genuine emotions.
Too Much of a Good Thing? Assessing Performance Tradeoffs of Two-Electron Compounds for Redox Flow Batteries
Authors: Neyhouse Bertrand J. , Fenton Alexis M. , Brushett Fikile R.
Published: May 2021

Engineering redox-active compounds to support stable multi-electron transfer is an emerging strategy for enhancing the energy density and reducing the cost of redox flow batteries (RFBs). However, when sequential electron transfers occur at disparate redox potentials, increases in electrolyte capacity are accompanied by decreases in voltaic efficiency, restricting the viable design space. To understand these performance tradeoffs for two-electron compounds specifically, we apply theoretical models to investigate the influence of the electron transfer mechanism and redox-active species properties on galvanostatic processes. First, we model chronopotentiometry at a planar electrode to understand how the electrochemical response and associated concentration distributions depend on thermodynamic and mass transport factors. Second, using a zero-dimensional galvanostatic charge/discharge model, we assess the effects of these key descriptors on performance (i.e., electrode polarization and voltaic efficiency) for a single half-cell. Finally, we extend the galvanostatic model to include two-electron compounds in both half-cells, demonstrating compounding voltage losses for a full cell. These results fundamentally show why multi-electron compounds with disparate redox potentials are less attractive than those with concerted electron transfer. As such, we suggest new directions for molecular and systems engineering to improve the prospects of these materials for RFBs.

Published: May 2021

We analyse the direction of the energy revolution from the dimensions of cleanness, electrification, intelligence, and ubiquity. Based on this, we highlight the importance of electricity in the Energy Internet and analyse the challenges faced by the development of the power grid. Then, we propose an electricity-centered energy comprehensive optimization model and set up baseline scenario and carbon neutral scenario, to achieve a systematic simulation of the path of Energy Internet to boost energy transition. The results show that the Energy Internet accelerates the process of clean energy supply, effectively promotes the development of the energy transition, and contributes to the realization of the carbon neutral goal. There are still many problems in the development of the Energy Internet. In order to accelerate the transformation of the energy system and the power industry, it is necessary to establish a sound energy policy system, encourage clean energy consumption, and use the construction of the Energy Internet to achieve optimal allocation of resources.

Published: May 2021

A 52-year-old African-American male patient with end-stage renal disease due to hypertension underwent deceased donor kidney transplant procedure with no immediate complications. The postprocedure complications, interventions, and course were abstracted by chart review. The ureteric stent was removed with flexible cystoscopy on postoperative day (POD) 24. 24 hours later, the patient presented with abdominal pain and inability to urinate. An urgent ultrasound and noncontrast CT scan showed grade 4 hydronephrosis of the transplanted kidney. A percutaneous nephrostomy stent was placed for urinary diversion. A large ureteric hematoma filling the lumen of the mid to distal ureter was identified on the nephrostogram and was evacuated. A follow-up nephrostogram on POD 44 revealed a distal ureter stricture and persistent well-formed midureter filling defect. A repeat nephrostogram performed at POD 72 was done with stricture dilatation, internalization of stents, and removal of a percutaneous nephrostomy tube. The patient was maintained on antibiotics for UTI prophylaxis throughout the course.

Published: May 2021

(analítico)Se presenta una investigación sobre el ciclo de movilizaciones feministas universitarias de 2018, en la cual jóvenes estudiantes chilenas denunciaron violencia y acoso en instituciones de educación superior; visibilizando que la violencia contra las mujeres ha sido normalizada e invisibilizada, pues, se encuentra arraigada en una cultura sexista. Así, se propone un objetivo doble: por un lado, identificar cuáles manifestaciones de la violencia de género fueron las principales catalizadoras de dichas movilizaciones; y, por otro, determinar cómo tales violencias se expresan en los contextos universitarios desde la voz de sus protagonistas. Este movimiento introdujo críticas profundas a la concepción de educación superior y acabó por revelarla como un campo de continua disputa política articulada con la genealogía del movimiento estudiantil chileno y con el resurgimiento de feminismos jóvenes en Latinoamérica.

Unrestrained Individuation
Authors: Ercolino Stefano
Published: May 2021

This essay focuses on a little-understood phase of Franco Moretti’s work that spans 1976 to 1986. My aim is to shed light on Moretti’s cultural background as it was formed in that period and to account for the transition from the Trotskyist, politically-militant stance of his first book, Literature and Ideologies in England in the 1930s, to the idiosyncratic, seemingly disengaged character of Signs Taken for Wonders and The Way of the World. Adorno’s concept of ‘unrestrained individuation’ plays a crucial role in the argument. Following a personal political crisis, Moretti opted to enact a form of critical individuation, encoding the explicit social antagonism of the earlier years within a highly personal style and a new theoretical eclecticism. In this way, by disguising it as an alluring form of individualism, Moretti managed to smuggle an antagonistic critical discourse into an increasingly neoliberal world that would soon prove hostile toward it.
Impact of Public Health Equalization on Residents’ Health and Economic Growth: An Empirical Analysis from Jiangsu Province (2006–2015), China
Authors: Chen Zhengyang , Xu Xinglong , Qian Dongfu , Zhan Xiang
Published: May 2021

Public health equalization has a significant impact on residents’ health and economic growth. Recently, studies suggested the persistence of series of public health unequal issues in China, such as imbalanced government financial investment, unreasonable configuration of public health resources, etc. The healthcare system in Jiangsu province is a microcosm of the pattern of healthcare delivery in China. Identifying developmental differences in Jiangsu and consequential effect on healthcare output can serve as a good reference for comparing performance of healthcare facilities within China in general. Based on the Model of Health the Healthy Production from Grossman and Lucas’ New Endogenous Economic Growth Model, we selected data from China Statistical Yearbooks and Jiangsu Statistical Yearbooks. 13 cities in Jiangsu province were divided into three groups, categorized as economically developed areas, relatively economically developed areas and less-economically developed areas. The panel cointegration model and e PVECM PVECM error correction model based on E-G two-step method are utilized for empirical research. During the period of 2006–2015, there were differences between the short term effect and long term effect on regional development resulted by the public health equalization level of Jiangsu Province. In the short term, the healthcare investment equalization level has been improved, to a certain extent, which executes a certain promoting effect on the people’s health development and regional economic growth in the long term, which restraint the improvement and development of long term public health equalization level and stimulating on the residents’ health and economic growth. The government of China in general and Jiangsu province in particular could ensure the efficiency of public health human resources, reform the public hospital internal system and establish an effective competition system, aiming to improve the public health equalization and promote balanced development of residents’ health and economic growth.
Interpretation of the Japanese Great White Tower Novel from the Perspective of Cognitive Poetics
Authors: Xu Tingting
Published: May 2021

As the representative of postwar Japanese female writers, Yamazaki Toyoko expressed the theme from her unique perspective, sharp language and realistic techniques, revealing the contradictions and conflicts in Japanese society. Yamazaki constructs the conceptual metaphor of “the system is the white tower” running through the novel, so that readers could gradually change their cognition and realize an unknown confrontation and competition between good and evil in the hospital. The Great White Tower revolves around the medical insider and the dispute between doctors and patients. The characters in the novel are real and full, which well shows the struggle for professional titles, the erosion of human nature. Based on this, from the perspective of cognitive poetics, this paper mainly uses conceptual metaphor, archetypal category theory and event framework theory to interpret the novel and analyzes the characters of novels, explores the themes of novels and reveals the explanatory power of cognitive poetics to literary novels. Through the dynamic construction of the character image and conflict escalation, it is obvious that money-power politics caused by rapid development of capitalist economy, authority worship and excessive power caused by the deep-rooted hierarchical culture also further triggered the pursuit of professors’ authority and the struggle between different interest groups.
EFSO at Different Geographical Locations Verified with Observing System Experiments

Published: May 2021

An ensemble-based forecast sensitivity to observations (EFSO) diagnosis has been implemented in an atmospheric general circulation model–ensemble Kalman filter data assimilation system to estimate the impacts of specific observations from the quasi-operational global observing system on weekly short-range forecasts. It was examined whether EFSO reasonably approximates the impacts of a subset of observations from specific geographical locations for 6-h forecasts, and how long the 6-h observation impacts can be retained during the 7-day forecast period. The reference for these forecasts was obtained from 12 data-denial experiments in each of which a subset of three radiosonde observations launched from a geographical location was excluded. The 12 locations were selected from three latitudinal bands comprising (i) four Arctic regions, (ii) four midlatitude regions in the Northern Hemisphere, and (iii) four tropical regions during the Northern Hemisphere winter of 2015/16. The estimated winter-averaged EFSO-derived observation impacts well corresponded to the 6-h observation impacts obtained by the data denials and EFSO could reasonably estimate the observation impacts by the data denials on short-range (from 6 h to 2 day) forecasts. Furthermore, during the medium-range (4–7 day) forecasts, it was found that the Arctic observations tend to seed the broadest impacts and their short-range observation impacts could be projected to beneficial impacts in Arctic and midlatitude North American areas. The midlatitude area was located just downstream of dynamical propagation from the Arctic toward the midlatitudes. Results obtained by repeated Arctic data-denial experiments were found to be generally common to those from the non-repeated experiments.
Financial Performance and Gender Diversity: The Moderating and Mediating Effect of CSR Disclosure and Expenditure of Listed Firms in India
Authors: Oware Kofi Mintah , Mallikarjunappa T.
Published: May 2021

The study examines the moderating and mediating effect of corporate social responsibility (CSR) disclosure and CSR expenditure on the association between listed firms’ financial performance and gender diversity. There are 80 listed firms with 800 firm-year observations from 2010 to 2019 that qualified for the study using the Indian stock market. The first finding shows a negative association between financial leverage and gender diversity. The second finding shows that the implementation of CSR disclosure hurts the improvement of gender diversity. The third finding shows that CSR expenditure improves gender diversity of listed firms in an emerging market. The fouth finding shows that CSR expenditure positively mediates the negative association between financial leverage and gender diversity. The fifth finding shows that CSR disclosure does not mediate the association between financial performance (return on assets, price to book ratio and financial leverage). The sixth finding shows that CSR expenditure negatively moderates the negative association between return on assets and gender diversity.
Probing Chinese Perception on the Importance of Social Capital in Entrepreneurial Success
Authors: Yue Liu , Rivera John Paolo R.
Published: May 2021

The link between entrepreneurship and economic growth has been established in the literature. The potency of an entrepreneurship ecosystem, driven by the role of financial capital, is now a determinant of an economy’s success. The People’s Republic of China has been successful on this expanse. However, in this conceptual study, we explicate the role social capital play in entrepreneurial venture growth. By conducting a survey on Chinese entrepreneurs, cross tabulating their categorical responses and conducting contingency table analysis, we get to illustrate how they see social capital as a facilitating factor of their entrepreneurial success. Results revealed that Chinese entrepreneurs believe that together with financial capital and government assistance, having more social capital is critical in developing start-ups, attracting more investments and acquiring a bigger market share. However, a premium is placed on technical skills and enterprise planning than personal charisma. Results were validated and augmented earlier results on Chinese perceptions on what makes entrepreneurial ventures successful.
Does Sentiments Impact the Returns of Commodity Derivatives? An Evidence from Multi-commodity Exchange India
Authors: Simon Aneeta Elsa , Manu K.S.
Published: May 2021

The advancements in technology, increased accessibility to various modes and platforms of communication, and increased willingness on the part of participants to share their ideas/opinions has resulted in huge amounts of data on the World Wide Web, hence, easily available to impact decision-making. Furthermore, commodity prices are primarily driven by demand and supply, wherein such news is open to the cognitive thinking of individuals. Thus, using the principles of natural language processing, which combines concepts of linguistics, computer science and artificial intelligence, helps in improving the accuracy of price determination. Therefore, this article aims to examine the relationship between sentiments conveyed through various sources and the performance of India’s largest commodity market, multi-commodity exchange (MCX). The correlation and causation between sentiment scores extracted from such textual content and the daily returns of select commodity derivatives are analysed. The results show varying levels of significance of sentiments on the returns of commodity contracts and imply that there is an increased scope of using such unstructured content in the field of finance.

Entrepreneurs are significant contributors in the economic growth of a nation. Generally, economic growth of any country is largely determined by the financial and social development of the women entrepreneurs. The objective of the study is to analyse the influence of perceived motivational independent variables on anticipated success of female venture holders. The existing literature arouse the need of significant study in the field of perceived motivation factors of women entrepreneurs, specifically in Madhya Pradesh, and an understanding of women’s participation in economic development of the state. A self-designed structured questionnaire was administered personally among female entrepreneurs engaged in small-scale businesses in different regions of Madhya Pradesh. The compilation of findings was done on the basis of empirical analysis of the explored motivational and the anticipated success factors. Accordingly, the hypotheses were framed and an eight-dimensional model making use of regression analysis is developed for identifying a meaningful relationship between explored inspirational and success accomplishment factors. The results of analysis state that the factors financial freedom and professional competency have greatest influence on the overall success of the venture followed by entrepreneurial attitude and supportive environment. Variables like prosperity and receptiveness are the least motivating factor towards the success of the venture.
Fit Perception and Engagement: The Mediating Role of Work Meaningfulness
Authors: James Robinson
Published: May 2021

Research on engagement has gained considerable attention in recent years as it is a strong predictor of a range of positive individual and organizational outcomes. There is a question of why the level of the engagement is different from employee to employee in an organization, though they are provided with the same resources. This study aims to investigate the influence of fit perception on engagement and the role of the employee’s psychological condition (work meaningfulness) on this relationship. This study mainly employed a survey research strategy, and data were primarily garnered from a questionnaire. This study was conducted among 145 respondents from the public sector organizations in Sri Lanka. Partial least-square structural equation modelling was employed to analyse the generated data. In this study, the researcher has conceptualized fit perception as a higher order construct comprising Person Job fit and Person Organization fit. The study revealed that fit perception positively influences employee engagement, and this relationship is mediated by work meaningfulness. This study contributes to the literature by deepening the understanding of the fit perception and engagement relationship by introducing work meaningfulness as a mediator variable. By highlighting how engagement is influenced by fit perception and work meaningfulness, this study facilitates practitioners to build and maintain an engaged workforce. Further contributions of this study, the avenue for future research, and study limitations are presented in detail at the end of this article.
Authoritarian downgrading, (self)censorship and new media activism after the Arab Spring

While considerable scholarly attention has focused on analysing the role and impact of new media during the Arab Spring uprisings of 2010–2011, comparatively little research has been devoted to examining how online activism has changed in response to the regime stabilisation measures undertaken by the governments which survived the unrest. Characterising the de-liberalisation policies of post–Arab Spring states as ‘authoritarian downgrading’, this article considers how the growing involvement of authoritarian regimes in online spaces is impacting activists’ use of new media technologies. Adopting Bahrain as a case study, we present the results of a survey of Bahraini political activists conducted in 2017 and consider whether activists’ perceptions of their online safety and security are impacting their use of new media through behaviours such as self-censorship, the adoption of pseudonyms and the preferencing of direct messaging apps over Arab Spring-era social media platforms.

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) destaca-se como uma das principais pragas do tomateiro na atualidade. O objetivo desse trabalho foi avaliar a eficiência do uso de extratos vegetais como método de controle de lagartas de T. absoluta em plantas de tomateiro. Os extratos de neem (Azadirachta indica A. Juss), timbó (Lonchocarpus negrensis Benth), Aloe vera (L.) Burm.f. (Aloefertil®) e tabaco (Nicotiana tabacum L.) foram aplicados sobre as folhas dos tomateiros e, para o grupo controle, aplicou-se água. O delineamento experimental foi inteiramente casualizado, composto por cinco tratamentos e cinco repetições. As pulverizações ocorreram cinco dias após a inoculação das lagartas neonatas e a mortalidade foi avaliada aos três, sete e 10 dias após as aplicações dos tratamentos. O produto comercial Aloefertil® apresentou baixa eficiência de controle (menos de 25%). Os demais tratamentos apresentaram eficiência de controle maior que 80% no início das avaliações, atingindo 100% de eficiência no controle de lagartas de T. absoluta aos 10 dias após a aplicação. Os resultados demonstram potencial dos extratos vegetais testados para o controle de lagartas de T. absoluta como uma estratégia interessante para reduzir os danos causados por esta praga.
