Influence of Motivation on Students’ Academic Achievement in the Teaching of Junior Secondary Three Social Studies in Jalingo Metropolis

This study aimed to ascertain Influence of Motivation on Students’ Academic Achievement in the Teaching of JSS III Social Studies in Jalingo Metropolis Taraba State. Three research questions were raised to guide the study, and descriptive survey research design was used for the study. The target population was 3150 students covering all the 17 public secondary Schools across Jalingo metropolitan. 320 respondents were randomly sampled from five selected Junior Secondary Schools, and a 30-item research instrument, based on 4-point Likert scale, tagged Motivation for Academic Achievement Questionnaire (MAAQ), developed by the researcher and dully vetted by three specialists in measurement and evaluation, guidance and counselling and educational psychology in the Faculty of Education of the University, was used for data collection. Test-rest was used to ascertain reliability of the research instrument using Pearson Product Moment Correlation technique which yielded a coefficient of 0.67. The data collated was analysed using simple frequency count and mean, and the decision mean point was 3.00. It was concluded that intrinsic and extrinsic motivation in a proper blend has the potency to improve students’ academic achievement in social studies. The study finally recommends among others that, students should be conscientised as well as be empowered to realize that they play the most important role in motivating themselves first, before anyone else; and also social studies alongside other teaching subject areas be made interesting so as to arouse and sustain students’ interests and enhance learners’ achievement motivations.
Time-reversal duality of high-efficiency RF power amplifiers

The similarity between RF power amplifiers and rectifiers is discussed. It is shown that the same high-efficiency harmonically-terminated power amplifier can be operated in a dual rectifier mode. Nonlinear simulations with a GaN HEMT transistor model show the time-reversal intrinsic voltage and current waveform relationship between a class-F amplifier and rectifier. Measurements on a class-F-1 amplifier and rectifier at 2.14 GHz demonstrate over 80% efficiency in both cases.
Experimental investigation of the flow field of a ceiling FAN

A ceiling fan is the predominating comfort provider in tropical regions worldwide. It consists of an assembly of an electric motor with 3–4 blades suspended from the ceiling of a room. Despite its simplicity and widespread use, the flow induced by a ceiling fan in a closed room has not been investigated, and sub-optimal designs are in wide use. There is vast potential for energy conservation and improved comfort by developing optimized fan designs. This work develops a fundamental understanding of the flow characteristics of a ceiling operating inside a closed room. Using smoke from thick incense sticks, the flow field created by the ceiling fan is visualized. In most regions, the flow is periodic and three-dimensional. Vortices are seen to be attached to the blade tip and hub, which reduces downward flow and increases energy consumption. Only the middle 75% of blade actually pushes the air downwards, and the comfort region is limited to a cylinder directly under the blades; velocities in this region were measured with a vane anemometer. Winglets and spikes attached to the blade tip disrupted the tip vortex, and increased downflow by about 13% without any increase in power consumption.Copyright © 2004 by ASME
The Role Of Word Of Mouth’s Value Co-Creation On The Achievement Of Sustainability

Consumers who buy their products through e-commerce are beginning to pay attention to a company's corporate social responsibility (CSR) status. Due to technological advancements, information became more transparent. Based on this phenomenon, research is required to determine the extent to which word-of-mouth consumers collaborate to increase value in order to achieve sustainability. In this study, the achievements are examined from the perspective of co-creation on the word of mouth aspect, with dimensions of three main factors, namely, social, economic, and environmental. The hypothesis of this study was tested using structural equation modeling (SEM), which includes an assessment of the segments of the related pathways. A total of 297 Indonesians who have completed at least 20 transactions in e-commerce, expressed concern about three important aspects of sustainability: people, profit, and the planet. This finding demonstrates the importance of co-creation of word-of-mouth value in achieving sustainability. Further research into the moderating effects of more detailed aspects of the supporting ecosystem could be conducted in the future.
INSUFFICIENT DEFINITIONS OR A VAGUELY GRASPED NOTION? ON DEFINITIONS OF “IMPACT”

Introduction.For a better theoretical understanding of the notion of “impact” (introduced by E. Garfield in 1955) definitions and perceptions of the mentioned notion used in scientometric literature have been analyzed.Materials and methods.Analytical interpretation of the scientific literature related to this problem (since 1955). The author considers the concept “impact” in its initial meaning of ‘scientific impact’. Results.The existing and used meanings of the term “impact” either are treated as a synonym of “influence” or do not go beyond the concept of “strong impression”, or coincide with the meaning of the term “pertinence”, or refer to purely technical indicators.Discussion and Conclusions.The conclusion has been made that that it is unreasonable to consider “impact” as a key notion of scientometrics because the notion is not sufficiently defined.
Effects of PET fiber arrangement and dimensions on mechanical properties of concrete

Concrete has low tensile strength and crack resistance. Its weaknesses could be enhanced with the addition of fiber. Polyethylene terephthalate (PET) fibers are generally used in concrete as discrete reinforcement in substitution of steel fiber. Fibers obtained by hand cutting of PET bottles are in the form of straight slit sheets, which impart weaker bonding in concrete matrix. The bonding of the fibers however may be improved by using other geometries such as flattened-end sheet pattern. So far, there are no guidelines for defining the geometry and dimensions of PET fibers. Therefore, this paper focuses on the use of fibers with different geometries and dimensions and investigates their effects on the mechanical properties of concrete. Test results show that geometry of fibers has a small effect on the workability of concrete. The use of smaller dimensions of fiber improves the workability. Enhancement in the strength and energy dissipation capacity of fiber concretes was observed from the use of flattened-end fibers of smaller dimensions. Furthermore, a higher ultrasonic pulse velocity value was observed for concrete made from smaller fibers as compared to fibers of larger dimensions.
Evaluation of Two Methods for Identifying Trip Purpose in GPS-Based Household Travel Surveys

Data needs for developing travel demand models have increased at the same time that household travel survey (HTS) participation rates have generally fallen over recent decades. GPS-assisted HTS methods are recognized today as the most promising direction in further enhancement of individual travel data collection. The principal advantage of the GPS-assisted survey technology is that a full stream of locations visited by the person is identified with a high level of spatial and temporal resolution, but automatic identification of trip purpose remains an issue that is difficult to solve. This paper evaluates the performance of two methods, choice modeling and decision tree analysis, that can be used to build models capable of identifying trip purpose. The developed methods assume that basic household- and person-level data, typically collected in an HTS, are available, as are supporting spatial data sets. The methods presented are then evaluated for a case study that employed data from the 2011 Atlanta Regional Commission HTS. The developed models produced encouraging results with overall accuracy greater than 70% across all purposes and around 90% for mandatory activities (i.e., work and school). The performance of the developed models was evaluated in terms of error rates by purpose category and the impact of ancillary spatial data. The paper concludes with a summary of the findings and recommendations for practitioners.
Finding Echoes: An Exploration of Empathy Among Physiotherapists and Physiotherapy Students in Singapore

Background Empathy is an essential antecedent in motivating healthcare professionals to treat and care for their patients with compassion – few studies had explored empathy on healthcare workers. Currently, no data reported empathy amongst physiotherapists and physiotherapy students in Singapore. Objectives This study aims to: 1) measure and explore within- and between-group differences in empathy scores amongst physiotherapists and physiotherapy students in Singapore, and 2) compare the results with similar studies locally and overseas. Methods This cross-sectional survey recruited 187 participants (37 physiotherapists and 150 physiotherapy students) via convenience sampling. Participants completed the Jefferson Scale of Empathy (JSE) Health Professions (JSE-HP) and the JSE-Health Professions Students (JSE-HPS), correspondingly. The 20-item JSE-HP and JSE-HPS are validated self-reported questionnaires that measure clinical empathy using a 7-point Likert scale. Summed scores range from 20 to 140, with higher scores suggesting a higher level of empathy. Statistical analysis included descriptive statistics, independent-sample t-tests and one-way analyses of variance. Results The mean score of JSE-HP and JSE-HPS was 110.89±11.37 and 112.43±10.73, respectively. No statistically significant differences found between gender, physiotherapists and physiotherapy students, and years of study. However, physiotherapists scored significantly higher [5.08±1.24 (95% CI 4.67–5.49) vs 4.01±1.36 (95% CI 3.79–4.23), p < . 001 ] in the JSE components ‘Walking in Patient's Shoes’. Conclusion Physiotherapists and physiotherapy students in Singapore have similar empathy scores to their counterparts locally and internationally. No statistically significant differences in empathy scores were found. However, physiotherapy students were less able to understand patients' perspectives. This warrants further exploration in developing this vital attribute amongst students.
Performance measurement of supply chain management using the analytical hierarchy process

Performance measurement of supply chain management (SCM) is a rapidly growing multi-criteria decision-making problem owing to the large number of factors affecting decision-making. The right choice of performance metrics and measures is critical to the success and competitiveness of the firms in the era of globalisation. Recognising the multiple objective nature of the problem, this paper proposes the use of the analytical hierarchy process (AHP) methodology as aid in making SCM evaluation decisions. For pair-wise comparison in AHP, a survey methodology is used. The methodology presented can help firms to prioritise and formulate viable performance measurement strategies in the volatile and complex global decision environment from different balanced scorecard (BSC) perspectives. A demonstration of the application of this methodology in a real life problem is presented.
A dynamic formulation of ring oscillator as solitary-wave propagator

A nonlinear model of the ring oscillator is proposed. The oscillations are related to the irregularity or the kink-formed solitary wave, that is, an elementary phenomenon in a nonlinear system. According to the proposed model, we found that the higher harmonic generation cannot exist when the total number of stages is five or less.
The C. elegans SET-2 histone methyltransferase maintains germline fate by preventing progressive transcriptomic deregulation across generations

Chromatin factors contribute to germline maintenance by preserving a germline-appropriate transcriptional program. In the absence of the conserved histone H3 Lys4 (H3K4) methyltransferase SET-2, C. elegans germ cells progressively lose their identity over generations, leading to sterility. How this transgenerational loss of fertility results from the absence of SET-2 is unknown. Here we performed expression profiling across generations on germlines from mutant animals lacking SET-2 activity. We found that gene deregulation occurred in 2 steps: a priming step in early generations progressing to loss of fertility in later generations. By performing Within-Class Analysis (WCA), a derivative of Principal Component Analysis, we identified transcriptional signatures associated with SET-2 inactivation, both at the priming step and later on during loss of fertility. Further analysis showed that repression of germline genes, derepression of somatic programs, and X-chromosome desilencing through interference with PRC2-dependent repression, are priming events driving loss of germline identity in the absence of SET-2. Decreasing expression of identified priming genes, including the C/EBP homologue cebp-1 and TGF-β pathway components, was sufficient to delay the onset of sterility, suggesting that they individually contribute to the loss of germ cell fate. Altogether, our findings illustrate how the loss of a chromatin regulator at one generation can progressively deregulate multiple transcriptional and signaling programs, ultimately leading to loss of appropriate cell fate.
Statistical approaches to computing sample size in cluster randomized trials: a simulation study

Background: Cluster randomized trials, which randomize groups of individuals to an intervention, are common in health services research when one wants to evaluate improvement in a subject's outcome by intervening at an organizational level. For many such trials, sample size calculation is performed under the assumption of equal cluster size. For a variety of reasons, many trials that set out to recruit clusters of the same size end up with unequal clusters. This leads to a misalignment between the method used for sample size calculation and the data analysis, which may affect trial power. Various weighted analysis methods for analyzing cluster means have been suggested to overcome the problem introduced by unbalanced clusters; however, the performance of such methods has not been evaluated extensively. Methods: We examine the use of the general linear model for analysis of clustered randomized trials that assume equal cluster sizes during the planning stage, but for which the realized cluster sizes are unequal. We demonstrate the performance of three approaches using different weights for analyzing the cluster means: (1) the standard analysis of cluster means, (2) weighting by cluster size, and (3) minimum variance weights. Several distributions are used to generate cluster sizes to assess a range of patterns of imbalance. The variability in cluster size is measured by the coefficient of variation (CV). We assess the impact of using each of the three methods of analysis with respect to type I error and power of the study and how each are impacted by the variability in cluster size via simulations. Results: Analyses that assumes equal clusters provide a reasonable approximation when cluster sizes vary minimally (CV < 0.30). For analyses weighted by cluster size type I errors were inflated, and that worsened as the variation in cluster size increases, despite reasonable power. However, minimum variance weighted analyses best maintain target power and level of significance under scenarios considered. Conclusion: Unweighted analyses work well as an approximate method when variation in cluster size is minimal. However, using minimum variance weights performs much better across the full range of variation in cluster size and is recommended.
ANALYSIS OF ADV-VELOCITY MEASUREMENTS IN A VERTICAL SLOT FISHWAY MODEL

Since most waterways and rivers are anthropogenic modified, fishways are import hydraulic structures to stabilize and regenerate fish populations. Fish cannot migrate due to transverse barriers, thus, fishways enable upstream migration at these barriers. Vertical slot fishways are so-called technical fishways. They consist of a series of pools with sloping bottom. In contrast to pool-weir-fishways, vertical openings covering the entire water column enabling fish and benthos to migrate in-between pools. Vertical slot fishways are investigated since several decades – numerous hydraulic and numeric models were performed. Flow depths and velocities as well as turbulent features were of interest in these studies. But only since approximately 15 years extensive velocity measurements were conducted. Bottom slopes of 5 to 20 % were dominating. Also the data quality was addressed only briefly in respect to the turbulent flow features in the fishway and their influence on the measurement. In respect to that, the vertical slot fishway hydraulics in the herein presented hydraulic model were studied at two different slopes of 2.5 % and 5.0 % and different flow guiding elements. Flow guiding elements which are installed at the cross walls can provide deflection of the flow and therefore influence the passablity of fishways. Flow velocities were measured with an acoustic Doppler velocimeter in at a grid at two levels in two adjacent fishway pools. Herein, the results of the study of mean and turbulent flow characteristics are presented as well as an analysis concerning processing the ADV data.
A New Approach to Business Value Driven Planning for Data Projects

With the advent of new technology and digital trends, realizing value from data is a top priority for organizations. Along with this, the increased awareness that every business is a data business is beginning to take hold, especially in organizations engaging in data projects through the use of technologies such as Big Data, the Internet of Things and Advanced Analytics. However, it has been shown that there is a lack of understanding on how these projects will deliver value or benefit for the organization (LaValle et al. 2011). Or indeed, there is a lack of understanding on how to effectively manage and govern such projects and capabilities (Tallon 2013). In other words, implementing a data project does not automatically deliver business value, execute as expected, or make your organization data driven. To make your organization more effective when implementing data projects and developing a mature data capability, conversations need to be initiated between stakeholders and focus on the key problem to be solved by the data project. This focus is provided by answering six simple questions: why, what, when, who, where, and how. Yet, given the multitude of conversations that need to take place around the problem there are a lack of appropriate tools that can enable stakeholders to reach a shared understanding when planning data projects. Our research with major public and private sector organizations over the past three years has resulted in the development of a new ‘discursive template’ (c.f. Tsoukas and Chia 2002) (namely the Data Value Map - DVM to promote new transformative conversations within data projects while also producing a more rigorous and robust validation of the potential value of those projects. Moreover, this new approach is the output of four studies, which include: (i) a survey of over 50 organizations worldwide which examined the drivers, goals and barriers of data analytics, (ii) an analysis of 18 projects focused on developing data solutions, (iii) an analysis of over 100 implementations of the DVM, and (iv) one in-depth case study with multiple implementations. The objective of this paper is to present both our new approach for planning data projects along with the insights gained from these studies.
Colmatage des membranes par les minéraux et les protéines en cours d'électrodialyse conventionnelle

The aim of this project was to investigate the effect of the composition in calcium, and carbonate of a model whey protein solution to be treated by electrodialysis on the fouling of ion-exchange membranes. The pH of the concentrate was also controlled at different values to study its influence on membrane fouling. Membrane integrity was determined by membrane parameters and completed with fouling characterization by macroscopic and microscopic pictures, ATR-FTIR analyses and electron microscope images coupled to elementary X-ray mapping to identify the deposits. A protein layer was formed when the pH of the concentrate compartment was acidic, while a mineral deposit occurred when pH was basic. From these results, a stack arrangement is proposed to prevent the formation of mineral and protein fouling.
Conjugacy Of Moral's Development Features And Intellectual Competence And It's Components

The article studies the differences between older adolescents in terms of intellectual competence, conceptual, metacognitive and intentional abilities, depending on the severity of the characteristics of the moral development of the individual. The study involved 90 schoolchildren of older adolescents (15 years old). The methodological base of the study was: “Interpretation of the moral dilemma” (methodological method for assessing the characteristics of moral choices and the level of intellectual competence; indicators of the complexity of the interpretation text were evaluated), “Conceptual synthesis”, “Mood”, “Method for diagnosing the level of reflexivity”, Modification of the methodology “Comparison of Similar Drawings” by J. Kagan. The results of the study show the lack of conjugation of indicators of conceptual (conceptual), metacognitive (voluntary and involuntary), intentional (mentality and beliefs) abilities and characteristics of the moral and moral development of a person in older teens. Such facts probably speak in favor of the insufficient degree of formation of the construct of moral and moral experience of man. The established facts improve our ideas about the moral development of the individual, inspiring us to study the dynamics of this important construct. point - a formally written essay that describes descriptive judgments and does not express its own point of view; 2 points - an essay with the establishment of causal relationships; 3 points - expressing one’s own attitude to the problem and / or applying an analogy from another context in the presence of causal relationships.
