Development of motor control and behaviour in Asian elephants in the Kabini elephant population, southern India
Authors: Revathe T , Anvitha S , Vidya T N C
Published: August 2020

Although neonates of precocial mammals are capable of locomotory, sensory, nutritional, and thermoregulatory independence to some extent soon after birth, they attain their adult body mass more slowly than altricial mammals, allowing for an extended period of learning or perfecting skills to an adult-like degree. Asian elephants are precocial but are nutritionally dependent on the mother for at least two years and are long-lived and social. We wanted to examine the ontogeny of trunk motor control and various behaviours in Asian elephant calves and see whether the former develops faster than the latter since limb motor control is achieved soon after birth. We collected field data on trunk use, lateralisation, and behaviours from individually identified, free-ranging elephants in southern India and examined how they were affected by age and other factors. Unlike limb motor control, we found trunk motor skills and behaviours to develop gradually with age. Trunk lateralisation occurred very early on, was not highly dependent on trunk motor skills, and is probably not a developmental marker in Asian elephants. Adult-like behaviours that required low trunk usage emerged within 3 months, while some feeding behaviours emerged later. Calves spent less time resting and more time feeding as they grew, and their activity budgets resembled those of adults only after a year; hence, mother-offspring behavioural synchrony was low for young calves and increased with age. Behavioural development and trunk motor control in Asian elephants are both gradual processes, taking about a year to mature.
Caulonema differentiation in Funaria protonema
Authors: Johri Man-Mohan
Published: August 2020

The strategies and experimental approaches that led the author to demonstrate the role of auxin in caulonema differentiation in the protonema of the moss Funaria hygrometrica are discussed. In stationary suspension cultures, the status of cell differentiation is regulated by inoculum cell density and auxin level. At low inoculum cell densities, 2-5 µM indole acetic acid (IAA) led to the differentiation of 65-70% caulonema filaments in 5-6 days. Caulonema can also differentiate in auxin-free medium if buffered at pH 5.0 after a lag of 6±1 days. The duration of lag can be manipulated and the cells are capable of responding to auxin at a higher level (3-10 µM) and produce about 20% caulonema after 3 days. This responsiveness or sensitivity to auxin can be enhanced further by growing cells in a nutrient-limited medium buffered at pH 5.0. In this medium, addition of 3 µM IAA led to the differentiation of 75-80% caulonema and rhizoids within 3 to 4 days. Work done in other laboratories has shown that auxin promotes caulonema differentiation in the moss Physcomitrella patens by positively regulating two basic helix-loop-helix type of transcription factor genes namely root hair defective six-like1 (PpRSL1) and PpRSL2 (Jang and Dolan 2011, New Phytologist 192: 319-327).
The past and present of developmental biology in India
Authors: Ghaskadbi Surendra , Nanjundiah Vidyanand
Published: August 2020

This issue of The International Journal of Developmental Biology (Int. J. Dev. Biol.) is devoted to contributions to developmental biology from India. The articles have been organized thematically, beginning with historical accounts and personal reminiscences, followed by surveys of areas to which the authors’ own contributions have been substantial, and ending with reports of original research. The articles selected for the ‘history’ section are by those who have witnessed events from close quarters, and in most cases have contributed to the work in question. The range of articles is vast but cannot claim to be comprehensive. Some areas may have been left out inadvertently, either because we were unable to find anyone to cover them, or maybe in part because of not looking in the right place. Other areas are missed out because, much to our regret, authors did not deliver promised manuscripts on time. In short, the Special Issue is indicative of what went on and is going on in the field of developmental biology in India, but it does have gaps.
One of the most significant discoveries in Developmental Biology from an Indian laboratory - Iqbal A. Niazi and the role of retinoids in limb regeneration
Authors: Ghaskadbi Surendra , Nanjundiah Vidyanand
Published: August 2020

In this short commentary, we reflect upon the fascinating paper by I.A. Niazi entitled “Background to work on retinoids and amphibian limb regeneration: Studies on anuran tadpoles — a retrospect.” originally published in J. Biosciences (1996), and herein reproduced with the kind permission of the author and the Journal of Biosciences. It is fitting that this landmark publication is included in this India-related Special Issue of the Int. J. Dev. Biol., because it sketches the background to what is arguably one of the two most significant discoveries in Developmental Biology to come from an Indian laboratory. Besides being of intrinsic interest, it spawned an entire area of research, one that deals with the role of retinoids in morphogenesis and development generally.
Leela Mulherkar and the teaching of developmental biology
Authors: Ghaskadbi Surendra
Published: August 2020

The formal teaching of developmental biology in India began in the late nineteen-fifties at the Department of Zoology of the University of Poona. This was due to the efforts of Leela Mulherkar, who on her return from C.H. Waddington’s laboratory in Edinburgh, took up the teaching of embryology at the Master’s level. Mulherkar began using locally available material to teach how animals develop. They included the embryos of chicken, frog, garden lizard and molluscs, as well as organisms such as hydra and sponges. Her teaching was supported by an active research laboratory that used all these systems to address a variety of questions in embryology and teratology. She used chick embryo explants cultured in vitro extensively in her work. Teaching and research in embryology at the master’s and doctoral levels at Poona University subsequently led, in 1977, to the establishment of the Indian Society of Developmental Biologists (InSDB), which is among the most active scientific societies in India.

Published: August 2020

The work is devoted to a comparative analysis of the quantitative content of extractives and water-soluble polysaccharides isolated from the fruit bodies of mushrooms Grifola frondosa depending on the extraction methods. As objects of study used strain of fungi G. frondosa 2639, isolated from commercial mycelium. It was established that the yield of fungi in polypropylene bags (volume up to 4500 cm3) was 36.37%, differing little from the yield of fruit bodies in glass containers (volume 800–1000 cm3). Using the hydrolysis of extraction products it was found that the methods of extracting the fruit bodies of G. frondosa with water lead to the extraction of polysaccharides of different composition. It was established that when using extraction methods in the Soxhlet apparatus, boiling and maceration (25.0±1.0 °C), the yield of extractive substances from the fruit bodies of G. frondosa was within the literature data interval and amounted to 6.04, 5.81 and 3.45%, respectively. It was shown that the highest content of water-soluble polysaccharides in the fruit bodies of G. frondosa was found using the extraction method in the Soxhlet apparatus – 14.92 %, differing from boiling and maceration methods (25.0±1.0 °C) in 1.15 and 1.33 times. By HPLC it was found that when maceration extraction was used (25.0±1.0 °C) and boiling, the monomeric composition of the polysaccharides of the fruit bodies of G. frondosa is mainly glucose, mannose, fucose and rhamnose in a ratio of 1.0 : 0.9 : 0.4 : 1.3, respectively. During extraction in the Soxhlet apparatus, their ratio was 1.0 : 1.2 : 0.5 : 1.9.

Published: August 2020

Development of theoretical bases of optimization of the production process of biologically active substances in the cultivation of medicinal plants by modern methods of biotechnology is one of the main tasks of fundamental research in this area. The aim of this study was to study the content and features of the accumulation of elements in regenerants of medicinal plants grown on the nutrient medium Murashige-Skoog with different content of phytohormones. Regenerant plants in vitro culture actively accumulate elements (K, P, Ca, Mg, Na, Zn, Mn, Fe, B, Al, Cu, Pb, Sr, V, Cr, Ag, Mo, Ti, Ni, Co , Se, Cd). The content of the trace elements Mn, Zn and Cu that we studied was at the level of normal values for the vegetation of the continents, Fe in P. alba regenerants – much higher. The content of heavy and toxic metals Pb, Cd, As, Cr, Ni did not exceed the normal level in plants and the acceptable level for dietary supplements, plant-based tea, and medicinal plant materials. The high dependence of the accumulation of elements in plants-regenerants Iris spuria Art And Soul variety on the content of hormones in the nutrient medium was noted. Representatives of all three groups (macronutrients, trace elements and ultramicroelements) had a similar curve diagram. The maximum peak was located at a concentration of 2.5 µm BAP with auxins, then the coefficient decreased by 5 µm BAP, and the next lower peak was observed at 5.0 µm BAP+A. the Lowest value of KN was at a concentration of 7.5 µm BAP. The introduction of auxins at this BAP concentration stimulated another peak, and then the accumulation coefficient tended to increase at a concentration of 10.0 µm BAP. The revealed dependence makes possible the regulation and directed accumulation of elements necessary for the researcher in plant tissues.

Influence of the thermochemical processing (the cook) conditions and of the milling on characteristic of the waste paper with polyurethan and polyaziridin was studied. The waste paper was  reduced to the degree size of the particles 5...8 mm in mill of the dry grind and chemical processing under higher temperature (to 70 °C) by solution, contain sodium persulfate and hydroxide; duty of water 6. Duration of cook varied from 1 to 5 hours, expense of persulfate sodium varied from 2 to 12%, hydroxide sodium – from 0.5 to 3% from mass of the waste-papers.  The secondary fiber was obtaining by breaking-up of the pulp in the hydropulper.  The dependency of the length and factor of the form of the secondary fiber from conditions cook was absent. The slight width increasing of the fibers with the higher pH of cooking liquor was determined: from 26.5 мкм under pH 3–4 to 29 мкм under pH 8–9. The conjectural reason is swelling of the cell wall. The waste paper milling was executed in the «stream-barrier» machine. The strength properties of the paper correspond with the feature, inherent of the secondary pulp.

In this work, we obtained samples of carbon-containing materials from fibrous residues of rice husks and straw, husks of soybean and sunflower, cedar shells at temperatures of 300, 400, and 500 °С. The ash content (3.0–9.3%), the content of water-soluble substances (1.2–7.6%), the mass fraction of moisture (3.0–6.2%), and the pH values of the aqueous extract (5.4– 8.8) and bulk density (66–481 kg/m3) were determined. The IR spectra of carbon-containing materials from plant materials contain more pronounced bands of oxygen-containing functional groups in comparison with medical preparations and BAH coal. The samples are in an X-ray amorphous state, and with increasing firing temperature, the degree of carbon ordering networks increases. All samples have a layered fiber structure, which differs depending on the type of raw material and temperature. The sorption activity was studied with the respect to iodine (7.6–58.4%), methylene blue (4.2–35.8 mg/g) and methyl orange (5.2–64.4 mg/g), which changes depending on the type of raw material and the temperature of carbonization. It was shown that with an increasing firing temperature, the sorption activity of the samples increases. Samples obtained at 500 °C have a high iodine absorption capacity (50.8–58.4%), comparable with BAH activated carbon (60%), and can be used as inexpensive porous carbon materials.

O comércio é uma atividade presente nos estudos da Geografia, cada vez mais representativo no sistema produtivo da sociedade contemporânea (SILVA, 2014a; PINTAUDI, 2002). Os estudos sobre o comércio, associados a análise da atuação da mulher, não são recorrentes, por este motivo, buscamos investigar a atuação das proprietárias de estabelecimentos comerciais de Pau dos Ferros (RN). Esta cidade aparece como um centro regional que apresenta uma diversidade de estabelecimentos comerciais e de prestação de serviços (DANTAS, 2014; BEZERRA, 2016). Associamos essa discussão às lutas feministas na conquista pelo seu espaço e na quebra de paradigmas na sociedade, observando as dificuldades em que as mulheres adentrem ao mercado de trabalho em cargos de liderança em seu próprio negócio. Para a efetivação desta pesquisa nos apoiamos em obras que versam sobre os conceitos de comércio e consumo urbanos e gênero. Utilizamos dados secundários extraídos do IBGE e da Secretaria de Tributação de Pau dos Ferros, bem como a realizamos um trabalho de campo, mediante a aplicação de formulários de caráter quali-quantitativo (GOLDENBERG, 1997). Estudar a atuação da mulher como proprietária desses estabelecimentos comerciais nos fez compreender seu perfil e dificuldades à frente destes estabelecimentos na cidade.

Fitness-evaluated Adaptive Switching Simulated Kalman Filter Algorithm with Randomness
Authors: Ab. Aziz Nor Azlina , Ab Rahman Tasiransurini , Abdul Aziz Nor Hidayati
Published: August 2020

The original Simulated Kalman Filter (SKF) is an optimizer that employs synchronous update mechanism. The agents in SKF update their solutions after all fitness calculations, prediction process, and measurement process are completed. An alternative to synchronous update is asynchronous update. In asynchronous update, only one agent does fitness calculation, prediction, measurement, and estimation processes at one time. A recent study shows that the asynchronous SKF outperforms synchronous SKF. In this study, synchronous and asynchronous mechanisms are combined in SKF. At first, the SKF starts with either synchronous or asynchronous update. By evaluating the fitness, if no improved solution is found, the SKF changes its update mechanism. The decision to switch from synchronous to asynchronous or vice versa is made randomly. Using the CEC2014 benchmark test suite, experimental results indicate that the proposed adaptive switching SKF randomness outperforms the original SKF algorithm.

Published: August 2020

Simultaneous model order and parameter estimation (SMOPE) is a metaheuristic based system identification method. SMOPE was introduced using particle swarm optimization (PSO). There are several iteration strategies for PSO. The original work on SMOPE is based on synchronous PSO (S-PSO). However, in some works PSO using other iteration strategy is found to give better results. In this work, based on six system identification problems random asynchronous (RA-PSO) based SMOPE is found to have slight advantage over S-PSO.

Published: August 2020

An integrated algorithm for solving multi-objective optimisation problems using a dual- level searching approach is presented. The proposed algorithm named as dual-particle swarm optimisation-modified adaptive bats sonar algorithm (D-PSO-MABSA) where the concept of echolocation of a colony of bats to find prey in the modified adaptive bats sonar algorithm is combined with the established particle swarm optimisation algorithm. The proposed algorithm combines the advantages of both particle swarm optimisation and modified adaptive bats sonar algorithm approach to handling the complexity of multi-objective optimisation problems. These include swarm flight attitude and swarm searching strategy. The performance of the algorithm is verified through several multi- objective optimisation benchmark test functions. The acquired results show that the proposed algorithm performs well to produce a reliable Pareto front. The proposed algorithm can thus be an effective method for solving multi-objective optimisation problems.
Students’ preferences and teachers’ beliefs towards written corrective feedback
Authors: Tri Adhi Kencana Alviana
Published: August 2020

Writing skill has been considered as a crucial skill that EFL students need to master. One of the techniques usually employed by teachers to help students improve their writing is via Written Corrective Feedback (WCF). Although many studies have been conducted to test its effectiveness, fewer studies have examined students’ and teachers’ preferences and beliefs towards the usefulness of WCF. Therefore, the present study analyzed students’ preferences and teachers’ beliefs regarding WCF. The participants consisted of 35 EFL students and 5 EFL teachers enrolled in SMK Negeri 1 Bawang Banjarnegara, a vocational high school in Banjarnegara, Indonesia. The data were both obtained through written questionnaires for the students and interview questions for the teachers. The collected data were analyzed based on WCF types classified by Ellis (2008), specifically for certain types like direct, indirect, and metalinguistic corrective feedback. The result of the present study demonstrated that both students and teachers mostly agreed that students should receive WCF in large amounts. Both of them also agreed that teachers should provide comprehensive feedback which consists of correction and explanations. Finally, both of them also had similar opinions that form-focused errors should be prioritized for correction than content-focused errors.

Basically, the teaching and learning process will run smoothly if students feel comfortable with the learning activities; therefore, this research provides some appropriate suggestions for teachers in overcoming difficulties faced by students. The respondents of this study were junior high school students. This study used a questionnaire as an instrument to determine the extent of students' skills in English. This study also conducted data analysis by analyzing the importance of English in students' views, the difficulties encountered in learning English, and also the teacher's teaching strategies desired by students. The results of this study indicate that most students have some difficulties in speaking due to lack of confidence and skills such as pronunciation, vocabulary, and grammar. Likewise, the difficulty in listening is caused by students’ lack of vocabulary that leads to the difficulty in understanding conversations in English. To overcome this problem, teachers need to have strategies such as identification, diagnosis, prognosis, and assistance or therapy. This research can facilitate the teachers in knowing complaints about English language difficulties experienced by the students.

Published: August 2020

This study propose to explore the moderating role of audit quality on the relationship between IFRS adoption and earnings management as well as the effect of IFRS adoption on earnings management in the context of Bangladesh, as developing economy. Earlier literature document that the relationship among IFRS adoption, audit quality and earnings management are not conclusive. In case of IFRS adoption, it is incoherent which may be the result of difference in culture, practices and legal strength of the country. This study considers discretionary accruals as proxy of earnings management which is measured by the extended modified Jones model. Moreover, the influence of audit quality on the association between IFRS adoption and earnings management is also proposed to investigate. This study expects to explore the effect of IFRS adoption on earnings management in the context of developing country, like Bangladesh. It may be informative for the reader to understand the outcome of IFRS adoption, audit quality on earnings management in developing economy.

Authors: Baazaoui Hedi , Zaraï Mohamed Ali
Published: August 2020

The effect of firm characteristics on the disclosure of IAS/IFRS information can not be studied in isolation of the national context of the country of nationality or domicile of the firm. Starting from the assumption that the intrinsic characteristics of the firm depend significantly on its size and the country of his nationality, we chose to work on companies belonging to different trading indices and from countries with different cultures and levels of economic development. The selected countries are Tunisia, France and Canada since Tunisia differs from Canada and France mainly by the level of economic development (developing countries) and France differs from Canada by culture. Our sample includes 52 Tunisian companies (40 listed on the first market and 12 on the alternative market), 244 French companies (35 CAC40 Index (top 40 French firms) and 209 CACsmall (index of small Capitalization French firms)) and 223 Canadian companies (36 ^TX60 (first 60 Canadian companies) and 187 ^TX20 Index (Small Capitalization Canadian firms)). Our results showed that the determinants of the disclosure of IAS/IFRS information will vary depending on the nationality of the firm and also showed the importance of the nationality of the firm in explaining disclosed information since the proxy used "country" has significant coefficients.
