Some aspects of the Statistical Distribution of Upper Winds over India
Authors: RANGARAJAN S. , MOKASHI R. Y.
Published: April 2022

For a quantitative evaluation of the probabilities of occurrence of upper wind speed and directions, a number of standard statistical parameters like standard deviations of the zonal and meridional components of the wind and the correlation coefficients between them are required. Utilising all radio-wind observations of the 5-year period, 1959-1963, these statistical parameters have been computed for the standard geometrical heights 1.5, 3.0, 6.0, 9.0, 12.0,14.1 and 16.2 km a. s. l. for all the twelve months of the year for three representative stations in India, viz., New Delhi, Nagpur and Trivandrum. The brief theory underlying the use of the statistical parameters and the method of constructing the distribution ellipses are outlined. The verification of the procedure has been illustrated by four actual cases of wind distribution. The main features of the distribution of winds in the different seasons have been discussed. In general, there is a tendency for the upper wind distribution to be elliptical rather than circular.
Climatology of the Crop Seasons of India_2. Wheat
Authors: MALLIK A. K.
Published: April 2022

On the basis of the data collected under the All India Co-ordinated Crop Weather Scheme, the normal growth features and the yield of the wheat crop in India are discussed in relation to the climatology of the wheat crop season. The study covers 9 stations with data varying for periods from 13 to 20 years. Information is presented about the chronology and growth attributes of the crop, the average durations of the crop growth periods and the average climatic features of the crop season and their variability, separately, for each station and each of the growth periods. It is shown that while the principle of time variation with geographical co-ordinates operate in the sequence of the dates, at different stations, of sowing, flowering and harvesting of the  crop, as well as the lengths of the vegetative, reproductive and total crop life periods, only the length of the vegetative period conforms to Hopkins’ Bioclimatic Law' for North America' There appears to be a negative  relationship between the duration of the vegetative growth period and the maximum and minimum tempera tunes during the same period and also between the height attained by the crop and the maximum temperature during the vegetative growth period.
Unusually early and heavy snowfall over the Punjab Himalayas - A case study
Authors: DATTA R. K.
Published: April 2022

The Lahaul and Spiti valley in the Punjab Himalayas experienced a spell of severe snowfall in the third week of September 1962. This was unusually early for the area. The synoptic features which led to this  situation have been described in this paper.

 

The interesting point revealed in the present study is that the cold air outbreak from an anticyclone moving east and southwest from Ukrainian area in synchronization with the recurvature of the monsoon depression was the main cause of the snowstorm.

 

            The probable influence of the Urals has also been indicated.
Pronounced Humidity Dip associated with thundersqualls at Colaba, Bombay
Authors: SARMA V.VITTAL
Published: April 2022

On 30 and 31 October 1964 during the passage of thundersqualls over Colaba, Bombay relative humidity recorded pronounced dip of 29 and 17 per cent respectively. This led to an examination path the wind speed humidity changes associated with passage of squalls during the last 3 years 1962-1964. Frequency distribution of these change in relation to rain show that humidity dip is associated with squal1s occurring before rain while a rise in humidity during squall occurred either during ram or just following the rain. A plausible explanation for the change in the humidity during the passage of the downdraft from the cumulonimbus cell is given.

Authors: YEGNARAYANAN SUMATHI
Published: April 2022

A statistical investigation of all available Rawin data at 3.0, 6.0,9.0,12.0, 14.1 and 16.2 km above sea level, for five Indian stations, covering the years 1961 and 1962 is reported in this paper. The stations are Bombay, Calcutta, Madras, New Delhi and Trivandrum. The tables showing the mean meridional and zonal components together with the standard vector deviations for the two seasons, December-February and July-August are included. The vector mean winds and the standard vector deviations for each station are given. The distribution of winds at the different levels mentioned above are tested for circularity and found to be mostly noncircular for the stations south of Lat. 20"N and mostly circular for stations north of it.
The morphology of Great Geomagnetic Storms recorded at Alibag for the period 1905 to 1945 : Part 11- The Disturbance local time inequality, DS and the disturbance daily variation, SD
Authors: YACOB A. , SASTRI N. S.
Published: April 2022

In continuation of results of storm-time disturbance variations Dst(H,E,Z) presented in Part I of the paper, the characteristics of disturbance daily variation, SD, and the disturbance local time inequality, DS, in the magnetic elements H, E and Z, as derived from 74 great sudden commencement storms recorded at Alibag during the period 1905 to 1945 are examined and discussed here. The DS (H) and SD (H) predominate over those in the elements E and Z. The magnitude of DS(H) during the main phase of the storm is large and decreases rapidly during the recovery phase. The phase angle of the first harmonic of DS(H) increases systematically with storm-time, especially during the first five 6-hour intervals of storm-time. The DS and SD variations for Alibag compare well with those for Honolulu and Zikawei given by Sugiura and Chapman, while the first harmonic of DS for Huancayo appears to be enhanced in a small measure. The SD variations are similar in magnitude and phase to those derived by Moos for Colaba (Bombay) for the period 1872 to 1904. The storm-time  courses of D8t (H) and DS(H) for Alibag are about parallel to each other with a tendency for the minimum in DS(H) to be reached earlier than that of D8t (H)and their decay rates are about the same especially towards the later stages of their courses. Two decay rates are, however, noticed in the recovery phase of the average great storm. The decay rate of the earlier portion of the recovery phase is more rapid than that of the later portion, indicating the probability of two ring currents being associated with geomagnetic storms.

Authors: ALVI S. M. A. , PUNJABI K. G.
Published: April 2022

In this paper the diurnal, monthly and annual frequencies of squalls at 22 stations of India based on available records up to 1962 have been discussed. The mean seasonal percentage frequencies and the mean frequencies of occurrence of squalls from different directions in eight points of compass have also been worked out. Maps showing percentage frequencies of squalls with reference to their duration and maximum speed reached have been prepared and a comparison between the mean annual frequency of squalls and all India thunderstorm frequency has been made.
Radar upper wind measurements at New Delhi using Decca wind finding radar- Type WF 2
Authors: SHESHADRI N.
Published: April 2022

This note gives a brief description of the Decoa wind finding radar type WF2 acquired by the India Meteorological Department. An analysis of the series of upper wind measurements taken with this radar at New Delhi during the monsoon months, July to September 1960, and the winter months, December 1960 to February 1961, is given. The structure of the upper winds over New Delhi during these months as revealed by the composite wind velocity profiles, it also indicated. The ratios of the maximum wind speed to the mean wind speed between the ground level and level of maximum wind were computed for all these ascents and the mean Percentage ratio was found to be 2.78. The comparison of the radar upper winds with the Rawin winds indicate close of squalls agreement at lower levels and when the winds are light. However, at higher levels in winter the radar winds are within 50° stronger than the Rawin winds.

An improved radiosonde for the measurement of electric potential gradient in the atmosphere
Authors: SRIVASTAVA G. P. , SREEDHARAN C. R. , HUDDAR B. B.
Published: April 2022

The electrical potential gradient sonde developed by Venkiteshwaran and his co-workers and used during the I.G. Y. for regular soundings at Delhi and Poona though satisfactory for low altitude measurements was not quite suitable for high altitudes where the electric field is normally of the order of a few volt per metre or less. As a result of a series of experiments to improve its performance, the improved sonde now has a much faster response time with a very stable and consistent reference zero. Provision has been made to make the transmitter and the batteries much less temperature dependant throughout the sounding and to monitor the reference zero during the flight. The sonde thus has an accuracy of  ±1 volt per metre and has been continuously used during the IQSY successfully.

Authors: ROY N. SEN
Published: April 2022

In Dobson Ozone Spectrophotometer, the amplified a.c. component of the photomultiplier output is rectified by means of a rotating commutator for indication in the meter. An attempt has been made to replace this mechanical rectifying device by means of a simple crystal diode circuit with satisfactory results. With this, a sharp minimum in current value, and not a reversal of the meter current, indicates null point. Studies have been made to see its workability in different spheres of spectorphotometer operation.
A study of the Onset or the Monsoon over India during 1962 using TIROS IV Radiation Data
Authors: RAO P. KRISHNA
Published: April 2022

Infrared radiation data collected from the TIROS IV satellite during the months of April, May and the early part of June 1962 have been used to study the onset and advance of the monsoon over India. The data show the northward migration of the intertropical convergence zone with time. A sudden shift of the convergence zone near the equator to the southern tip of India occurs early in May. This apparently corresponds to the "burst of monsoon" over India; this conclusion is supported by other meteorological data. The TIROS IV radiation data also show that the intertropical convergence zone over Africa during the same period shifted northward, but in a more uniform fashion than the convergence zone over the Indian Ocean area.
Dry periods during the Southwest Monsoon season in Rajasthan West
Authors: MALLIK A. K.
Published: April 2022

Based on data for the period 1901-1950, the incidence of spells of 'no rainfall' in Rajasthan West, during the southwest monsoon season (June to September), has been studied, with week as the unit period of time and district as the unit of area. It has been shown that (i) the number of dry weeks shows a loose negative relationship with total rainfall and the number of rainy days, (ii) there is a pulsating character in the rainfall during the southwest monsoon season, (iii) years with too many or too few rainless weeks are experienced by many districts simultaneously, (iv) prolonged spells of rainless period are common at the commencement and cessation of the season; the second week of August is also a critical period for the setting in of prolonged dry spells. During the period 1901-1950, in the extreme case, in Jaisalmer district in 1918, the whole of the southwest monsoon season was rainless except for 34 mm of rain in the second half of July, (v) Rajasthan West can be divided into three zones, viz., Zone' A' consisting of Churu, Nagore and Pall districts with least number of dry spells, Zone 'B' consisting of Ganganagar, Jodhpur and Bikaner districts with the number of dry spells increasing and Zone 'C' consisting of Jalore, Barmer and Jaisalmer districts with maximum number of dry spells, increasing the basis of the duration of dry spells and their number, an index of "Extreme drought" has been worked out and the districts of southwest Rajasthan has been graded accordingly.

A note on evaluation of the Richardson Number in relation to forecasting Clear Air Turbulence
Authors: SASTRY P. S. N.
Published: April 2022

For forecasting clear air turbulence, Richardson’s Number Ri is one of the widely used parameters. With increase in air traffic and aircraft operating at very high altitudes, the necessity for providing accurate information on turbulence in clear air is keenly felt. To facilitate the evaluation or Ri as soon as the upper air messages are received, nomograms and tables have been worked out and two simple methods are described for calculating Ri quickly.

Incidence of Low Clouds at Bombay airport (Santacruz) with reference to Jet landings with the help of the Instrument Landing System (ILS)
Authors: SIROMANI P.
Published: April 2022

Santacruz airport constitutes a high traffic density area, with a- substantial number of jet aircraft movements. Aviation hazards at this airport get particularly accentuated during the monsoon season on account of the occurrence of very low clouds, strong gusty winds and poor visibility conditions in mist or haze, or showers. There are a- few important hill features a-round the airport, not far from the landing area.

 

The airport is equipped with standard radio navigational aids, namely, very high frequency omnidirectional range (VOR), Instrument Landing System (ILS), the Aerodrome Surveillance Radar (ASR). A precision approach radar (PAR) will become operational at this airport shortly. On the ILS the glide path angle has recently been reduced from 4 degrees to 3.3 degrees above the horizon, necessitating the approach of the aircraft generally at a lower altitude, the altitude above the middle marker being of the order of 561 ft only. The distance of the middle marker from ARP is 2972 m (1.6 n.m.). Fig. 1 is the instrument approach chart for the Bombay airport.

 

The aviation hazards that may be encountered by the jet aircraft especially in the monsoon season, on the phase of the final approach, have been discussed in this note with reference to climatological statistics and the synoptic climatology of this airport. It is hoped that the result arrived at will be of some practical value to pilots operating jet aircraft and to air traffic controllers.

Platelet-rich plasma and bone morphogenetic protein: bucomaxillofacial and bone regeneration
Authors: Yaguana Galarraga Daniel Alfonso , Romero Urdiales Luis Alonso , Manzini Régis
Published: April 2022

Introduction: Science has evolved at an accelerated pace in the last decades, due to the need to know more and more the human being and the environment that surrounds them. In the search for this knowledge, aiming to improve the quality of life and the treatment of diseases previously considered incurable, research, especially in the field of biotechnology, has transformed the day-to-day health professionals. The application of this biotechnology related to growth factors can be exemplified in the use of platelet-rich plasma (PRP), gel capable of modulating and accelerating some repair processes. Objective: The objective of this work was to review the concepts related to growth factors, as well as in relation to platelet-rich plasma as an adjuvant in bone regeneration therapies. Methods: The present study followed a systematic review model, following the rules of systematic review – PRISMA. This study focuses on the treatment of bone regeneration through platelet-rich plasma and morphogenetic protein (BMP). To this end, a survey was conducted in scientific articles in the databases PubMed, Medline, Scielo, Lilacs, and e-books. The Cochrane Instrument was used to assess the risk of bias of the included studies, and GRADE was used to classify the quality of articles to the type of study and scientific evidence. Results and Conclusion: Therefore, the use of PRP, which would accelerate the rate of bone formation, with bone morphogenetic proteins (BMPs), recombinant or autogenous, should be quite important and elucidative. The development of new research, seeking to use all known technology, will always be the best way for a short future to recognize what should be incorporated into the daily routine of medical and dental clinics, differing from what, for various reasons, whether it was just a marketing procedure or something. The greatest advantage of the use of platelet-rich plasma is its ability to accelerate the process of bone regeneration by increasing the number of growth factors present in human platelets. On the other hand, it is observed that one of its major disadvantages is the low life expectancy of these platelets in the recipient or graft bed. However, it is also known that the PRP technique would only accelerate a process of bone regeneration that normally already occurs and this process follows its path until the formation of the mature bone.
Major approaches to bucomaxillofacial bone regeneration and remodeling with the use of biomaterials: a systematic review
Authors: Sánchez Carlos Alberto , López Steven , Alvarez Orley , Kassis Elias Naim
Published: April 2022

Introduction: The number of dental implants in the world has increased, totaling more than one million procedures per year. The development of biomaterials has represented an important therapeutic tool in the correction of bone defects. The bone regeneration process is initiated by successive mitosis of mesenchymal and endothelial stem cells, as well as by activation of osteoblasts and vascular proliferation guided by platelet-derived growth factors (PDGF) and TGF-β. Objective: To present, through a systematic review, the main results involving bone formation and remodeling in the maxillofacial system using biomaterials, cells and molecules in the appropriate biological niche of human bone. Methods: The research was carried out from July 2021 to August 2021 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar, following the Systematic Review-PRISMA rules. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: A total of 225 articles were found. After the selection process, 95 articles were recruited for analysis, 44 articles were selected and 43 articles were used in this study to compose the textual part. The selected articles had moderate quality in their clinical trials. The bias risks found do not affect the reliability of the results. As main findings, it was found that the osteoinduction process is influenced by several factors, requiring the presence of inducers, which include β-glycerolphosphate, ascorbic acid and dexamethasone. Mesenchymal cells acquire the morphology and components of osteoblastic membranes and start to express alkaline phosphatase to deposit extracellular matrix rich in calcium and certain proteins, such as osteopontin and osteocalcin. Bone morphogenetic proteins function as growth factors with a specific role in the proliferation and differentiation of mesenchymal stem cells present in the lesion's niche. Platelet-rich fibrin (PRF) stimulates bone regeneration more efficiently. Studies have reported that the addition of PRF with bone graft is associated with positive clinical results and is a good method of manipulating the bone graft during insertion into the maxillary sinuses and it stimulates bone regeneration. Conclusion: Optimized bone regeneration is a matter of great research to accelerate the osseointegration process, leading to reduced waiting time before any subsequent procedure. The balance between the biomaterial, mesenchymal stem cells, fibrin formation and platelet activation are responsible for the process and performance of bone regeneration or formation.
Сравнение морфологических изменений щитовидной железы крыс послевлияния разных видов алиментарной депривации
Authors: Янко Р. В.
Published: April 2022

Целью данной работы было сравнение разных видов алиментарной депривации (АД) на морфологические изменения щитовидной железы (ЩЖ) крыс. Исследование проведено на 36 крысах-самцах линии Wistar в возрасте 15 месяцев. Одна группа подопытных крыс была под воздействием интервальной (1 день полное голодание / 2 дня стандартный рацион питания), а другая – частичной (пищевой рацион, сниженный по массе на 30 % по сравнению с контролем) АД. Общая продолжительность эксперимента составила 28 дней. Доступ к воде был свободным. Гистологические препараты ЩЖ готовили по стандартной методике. Гистоморфометрию цифровых изображений препаратов проводили с помощью компьютерной программы “Image J”. Показано, что воздействие АД разных видов имело однотипные по характеру морфологические изменения ЩЖ. Однако выраженность из-менений в паренхиме железы подопытных крыс после влияния интервальной АД про-являлась в большей степени, чем при частичном голодании. Изменения основных гисто-морфометрических показателей ЩЖ крыс, после воздействия АД, указывают о наличии признаков повышения её активности. Об этом свидетельствовало возрастание массы железы, уменьшение площади фолликулов, коллоида, внутреннего диаметра фолликулов, индекса накопления коллоида и относительной площади стромы, а также увеличение высоты фолликулярного эпителия, фолликулярно-коллоидного индекса, стереологического индекса резорбции, количества интерфолликулярных островков.

Published: April 2022

The current work pursues production goals, particularly from the prospect of expansion of pear tree nurseries. In our republic the great part of pear tree nurseries dries out due to the bacterial leaf blight, improper selection of rootstock and scion (grafter) varieties, as well as to the random selection of rootstocks. Analyses on the planting stock quality have been conducted during the work implementation in the nursery farm of Herher community considering the inosculation results of various rootstocks. Application of different rootstocks in the nursery farms promotes the establishment of saplings with high survival rate and productivity. It is impossible to develop the branch of horticulture in the Republic of Armenia without the operation of nuresery farm system and sustainable production of healthy, purebred, reliable and high quality planting material. It is relevant to use the seed plants of Willow-leaf pear tree and quince tree rootstock for the pear tree varieties investigated by our research group. Propagation via shrubs has been singled out as an efficient method for clonal rootstock propagation.

Published: April 2022

ABSTRACT: Adolescence and young adulthood are the most susceptible age groupsfor developing eating disorders and depression, for both males and females. In thisresearch, we aimed to study the association of depression and eating disorders instudents from different universities of Lahore. It was a quantitative and cross-sectionaldesign and the sample constituted of 327 university students of 17 to 25 years of age.Participants were selected through convenience sampling. Instruments 'EatingAttitudes Test-26' (EAT-26) and 'Center of Epidemiologic Studies Short DepressionScale-10' (CESD-10) were applied to assess presence of depression and eatingdisorders. A score of 20 and above on EAT-26 was considered a cut-off to determinesusceptibility to eating disorders, whereas 10 or more on CESD-10 was the indicatorsfor higher risk for depression. Descriptive statistics (mean, standard deviation,frequency and percentage) were calculated for all continuous and categorical variables.Chi square and odds ratio were applied to assess association between depression andeating disorders. The study participants had higher prevalence of depression than eating disorders (58.3% and 37% respectively). The risk of eating disorders was higher in depressed individuals, especially in young females (21 years old and younger), who also had higher susceptibility towards both depression and eating disorders. Individualsbelonging to middle-income families and those who paid rent were more depressed. Significant association was seen between being a day-scholar and higher risks of eating disorders. Although, results revealed that association between eating disorders and depression were not significant (p=0.226), but depressed participants had higher chances of having eating disorders.

ABSTRACT: Popularity of drinking yogurts is increasing due to significant health benefits, on the go lifestyle and unique valuable ingredients. For the production of drinking yogurt, the present study was being carried out. Effect of various times and temperatures of pasteurization was studied in respect of stability of the product as well as concentration of Aloe Vera gel extract and strawberry pulp was being optimized. A varying heating times and different temperatures of pasteurization (70oC, 80oC, 90oC and 100oC for 5 and 10 minutes) were used in this process. With the storage at refrigeration temperature, evaluation of product for various attributes was carried out including physicochemical (pH, total solids, acidity and viscosity), microbiological (total plate count) and sensory. Effect of storage, time and temperature was seen on yogurt pH that decreased during storage while DY100/10 showed minimum decrease (0.39). Whereas, significant increase was observed in acidity during storage, as DY100/10 showed minimum increase (0.17) while reduction in viscosity was observed and DY100/10 showed minimum reduction (46.33). DY70/5 showed the maximum reduction in viscosity (50) and highest increase in acidity (0.22). During storage, nonsignificant increase in total solids was seen while DY100/10 showed maximum increase (0.3). Increase in storage time led to the decrease in number of total plate count and the sensory attributes (appearance, flavor, sensory acidity, body and texture) were affected significantly. During 20 days of storage, maximum scores were awarded to DY100/10 while minimum scores were obtained by DY70/5. From the present investigation it can be concluded that the best drinking yogurt with respect to shelf life and its sensory acceptance is DY100/10 with a storage period of 20 days.

Knowledge-based intelligent systems might be used in the banking sector to automate customer service. One of the ways to represent knowledge that is both understandable by humans and readable by machines is by using ontologies. Whenever a customer queries its bank regarding specific products or services, the existing knowledge modeled in an ontology might be used by a customer service chatbot to answer it in an automated way. The existing manual information retrieval process from banking specialists is laborious and time-consuming. Specialists use natural language, visual representations, and common sense, often overlooking details. It is a great challenge to make a specialist's knowledge explicit, formal, precise, and completely scalable, which is the format required by a customer service chatbot. We propose a semi-automatic approach to retrieving banking information in Brazilian Portuguese texts with minimal specialist support. By combining Natural Language Processing techniques (e.g., syntactic analysis to obtain the logical meaning of sentences based on rules and its structure) and an ontology constructor library, it was possible to build a tool that receives texts from the banking domain and constructs an ontology that knowledge-based intelligent systems can use. Specialist support is only needed in intermediate refinement steps, thus optimizing the banking specialist's time. The use cases for investments, opening a banking account, and the comparison of the proposed approach show how we reduced manual labor in the information retrieval process by a factor of 40%. Our approach can identify more information in each sentence compared to a similar method found in the literature. The resulting ontologies can be used in a chatbot that automates customer support for a large Brazilian bank.
Does Learning Multidisciplinary Field of Biomedical Engineering Help Pandemic of COVID-19?
Authors: Hashimoto Shigehiro
Published: April 2022

The global community has accelerated the spread of the virus. Medicine alone cannot solve the pandemic. Changes of lifestyle enabled by new technology helps to coexist with viruses. The academic field has been divided into each specialized field. Modern communication tools (internet and cloud databases), on the other hand, promote multidisciplinary academic fields. The multidisciplinary field is not just a collection of fields, but a fusion among fields. Many problems in global society cannot be solved by a single disciplinarian. The global society is waiting for a multi-disciplinarian. For students, it is not easy to find the way to learn a multidisciplinary field. This depends on the curriculum, the textbook, the learning team, and the teacher (the adviser). "Biomedical Engineering" is one of the multidisciplinary fields. It has many related fields: biology, medicine, informatics, and engineering. The topic includes case studies related to COVID-19 in 2020 (education for the undergraduate and the graduate courses in Japan and Thailand) based on the author's experiences: from cross cultural to symbiosis.
A Transdisciplinary Approach to Differentiated Instruction
Authors: Hendel Russell Jay
Published: April 2022

Differentiated instruction (DI) improves student performance and student satisfaction especially when preliminary instructor training is provided. However, the DI literature is overwhelming, excessively challenging many instructors to create a DI for multiple learning styles. This paper employs a transdisciplinary approach to address this gap between theory and challenging operational implementation. #1) The discipline of architecture introduced the approach of universal design, advocating that new buildings be initially built to allow universal access; this contrasts with the prior method of attempting to comply with regulations after building completion, which is often costly and wasteful. #2) The discipline of neuro-psychology identifies higher cognitive brain function with (performance) executive function which in turn is simply implemented using a multiple-modality approach. This suggests that pedagogic emphasis should be given to initial universal instruction addressing several modalities in contrast to one current DI approach requiring a costly continual monitoring and evaluation of individual student learning styles. This multiple modality approach, derived from neuropsychology is consistent with a wide variety of learning theories. #3) The discipline of industrial psychology emphasizes goal-setting, the skillful breaking up of a complex task into component tasks each of which is clearly defined, achievable timely, but challenging. #4) Goal setting coupled with the self-efficacy approach introduced by the discipline of social psychology, with an emphasis on perceptions of the self as a key motivating factor in learning, advocate that use of software technology, with numerically differentiated difficulty levels, allowing each student to both self-assess and self-improve with their own actions (self-regulation) The transdisciplinary approach advocates numerous innovations for DI which it is hoped that other researchers and instructors will pursue.

Published: April 2022

This study aimed to assess the effectiveness of the Mother- Tongue Based Multilingual Education to the indigenous peoples’ learners in Palawan. Indigenous peoples’ learners and their teachers were the respondents of the study. Mean, frequency counts, percentages, Pearson moment correlation, t-test and ANOVA were the statistical tools employed in this study. Most of the grade three learner were in the appropriate age for their grade level, male, belong to big families, spoke Palaw’an at home, belong to Palaw’an ethnic tribe, lived in highlands, live with the core members of the family with large households, and were less privileged. Pupils’ level of academic performance in the core subjects using the three different mediums of instruction did not meet expectation. Teachers had difficulty in dealing with learners’ individual differences, interest and needs as well as integrating MTBMLE to other subjects. The academic performance of the learners was not influenced by their demographic profile except for gender. The learners’ academic performance in Science and Mathematics was influenced by the medium of instruction while the level of academic performance of the learners in the Language subjects was not influenced by the medium of instruction except for mother tongue.

Published: April 2022

There is limited availability of equity and long term capital for business, governments and private sectors which was caused by saving-investment gap. This study therefore examined the macroeconomic determinants of capital market development in Nigeria. The study made use of annual data sourced from various statistical bulletins of Central Bank of Nigeria and National Bureau of statistics spanning from 1986 to 2016. The underpinning theory for this study is Calderson –Rossell Theory (1991). The study employed ARDL Cointegration analysis and Error Correction Model to explore the macroeconomic determinants of capital market development in Nigeria. The findings from the study revealed that there is existence of cointegration between the macroeconomic variables and the stock market capitalization (SMC) which was used as proxy for capital market development. The ARDL Error Correction Model Long run results showed that virtually all variables have insignificant positive relationship with stock market capitalization though the coefficients of macroeconomic variables are small which were all below 25% compare to the value of stock trade (VST) that represents stock market liquidity which was very high about 92%. The adjusted R-square value showed that the determinant variables employed in this study can jointly explain about 44% of the systematic variation in stock market capitalization. Therefore, this study concludes based on the above results that stock market liquidity significantly contributed to the growth of capital market development rather than macroeconomic variables. In line with the findings of this study, it was recommended that the government of Nigeria should improve on the macroeconomic variables through effective resetting of macroeconomic policies.

Published: April 2022

This study aimed to examine the role of behavioural intention to use m-Government services from Malaysian citizens perspectives. Drawing upon this aims, this study proposed personal innovativeness as a moderating variable in UTAUT2; performance expectancy, effort expectancy, social influence, facilitating condition and price value in predicting the behavioural intention to use the m-Government services. 354 data were collected through a self-administered questionnaire and was analysed using structural equation modelling to test the hypothesis. The findings found that performance expectancy, effort expectancy, social influence, facilitating condition and price value are the important determinant in influencing users’ behavioural intention to use of m-Government services. Interestingly, this study found the significant moderating effect of personal innovativeness in a relationship of performance expectancy and effort expectancy on behavioural intention. This study has extended the understanding on the role of personal innovativeness towards users’ behavioural intention to use m-Government services.
