A Novel Dataset for Aspect-based Sentiment Analysis for Teacher Performance Evaluation
No full textThe dataset was created by collecting student feedback from American International University-Bangladesh and then labelled by undergraduate-level students into three sentiment classes: positive, negative, and neutral. The dataset was then cleaned and preprocessed to ensure data quality and consistency. The final dataset contains more than 2,000,000 student feedback instances related to teacher performance. This dataset can be used to develop and evaluate ABSA models for teacher performance evaluation

Design Methods of Strategic Decision Support Solutions for B2C Business Managers
No full textThis chapter reviews methods to develop a decision support system (DSS) for small business managers. The primary objective is to support managers, making strategic decisions for achieving competitive advantages in the business-to-consumer (B2C) e-commerce environment. Many researchers in the DSS domain utilized various methods to design information systems (IS) solution, mostly intended for large businesses. None of the researchers have considered the business environment as a knowledge source for DSS development of small business strategic decision support needs. User-centered design (UCD) and design science research (DSR) method were adopted for DSS development. DSR was appropriate because it addresses the real-world application environment where research problem or opportunity are defined. Multiple case studies and web content analysis were carried out for understanding business problems, needs, and system requirements. This study used the qualitative and descriptive data analysis methods. The findings suggested developing a DSS solution to meet the small business strategic needs. </jats:p

A new charging scheme for ATM based on QoS
No full textPhDNew services are emerging rapidly within the world of telecommunications. Charging
strategies that were appropriate for individual transfer capabilities are no longer appropriate
for an integrated broadband communications network. There is currently a range of
technologies (such as cable television, telephony and narrow band ISDN) for the different
services in use and a limited number of charging schemes are applicable for each of the
underlying technologies irrespective of the services used over it. Difficulties arise when a
wide range of services has to be supported on the same integrated technology such as
asynchronous transfer mode (ATM); in such cases the type of service in use and the impact
it has on the network becomes much more important. The subject of this thesis, therefore,
is the charging strategies for integrated broadband communications networks. That is, the
identification of the requirements associated with ATM charging schemes and the proposal
of a new approach to charging for ATM called the “quality of service based charging
scheme”.
Charging for ATM is influenced by three important components: the type and content of a
service being offered; the type of customer using the services; and the traffic characteristics
belonging to the application supporting the services. The first two issues will largely be
dependent on the business and regulatory requirements of the operators. The last item, and
an essential one for ATM, is the bridge between technology and business; how are the
resources used by a service quantified? Charging that is based on resource usage at the
network level was the prime focus of the research reported here.
With the proposed charging scheme, a distinction is first made between the four different
ATM transfer capabilities that will support various services and the different quality of
service requirements that may be applicable to each of them. Then, resources are
distributed among buffers set-up to support the combination of these transfer capabilities
and quality of services. The buffers are dimensioned according to the M/D/1/K and the
ND/D/1 queuing analysis to determine the buffer efficiency and quality of service
requirements. This dimensioning provides the basis for fixing the price per unit of resource
and time. The actual resource used by a connection is based on the volume of cells
transmitted or peak cell rate allocation in combination with traffic shapers if appropriate.
Shapers are also dimensioned using the quality of service parameters. Since the buffer
4
efficiency is dependent on the quality of service requirements, users (customers) of ATM
networks buy quality of service. The actual price of a connection is further subjected to a
number of transformations based on the size of the resource purchased, the time of the day
at which a connection is made, and the geographical locality of the destination switch.
It is demonstrated that the proposed charging scheme meets all the requirements of
customers and of network operators. In addition the result of the comparison of the new
scheme with a number of existing, prominent, ATM charging schemes is presented,
showing that the performance of the proposed scheme is better in terms of meeting the
expectations of both the customers and the network operators
Effect of dietary supplementation with full-fat silkworm (Bombyx mori L.) chrysalis meal on growth performance and meat quality of Rhode Island Red × Fayoumi crossbred chickens
No full textThe objective was to study the effect of the partial substitution of soybean meal and oil with full-fat silkworm (Bombyx mori L.) meal (SWM) in the diet of growing chickens, on their growth and meat quality traits. A total of 195 1-day-old chicks of both sexes were allocated to 15 littered floor pens and assigned to three dietary treatments (5 replicates/treatments) until 8 weeks of age: a commercial diet (Control) and other two diets with an inclusion of either 25% (SWM25) or 50% (SWM50) SWM. At 8 weeks of age, two males/replicates were slaughtered and carcases dissected to compute yields. Pectoralis major muscle was subjected to pH and L*a*b* colour values, proximate composition and fatty acid profile analysis. All chickens showed satisfactory growth performance throughout the trial, with the best growth being observed in the SWM25 group. Carcase traits remained unaffected by the dietary treatment, but SWM25 chickens had a higher breast yield (p <.05) than the Control group. The pH of SWM50 breasts was higher than Control (p <.01). Dietary treatments affected meat protein content, differing between SWM25 and SWM50 (22.2 versus 23.3%, respectively; p <.05). SWM dietary inclusion increased n-3 PUFA and lowered the n-6 PUFA proportions in a level-dependent manner. Consequently, n-6/n-3 ratio diminished, thus improved, with the dietary SWM inclusion. Results showed that it is possible to partly substitute soybean meal/oil with SWM in the diet of chickens, ensuring satisfactory performance and carcase traits, and providing meat with a healthier n-6/n-3 ratio.Highlights Silkworm (Bombyx mori) chrysalis is a possible sustainable feed ingredient for growing chickens, alternative to conventional soybean. The dietary inclusion of silkworm full-fat meal in chicken diets provided satisfactory growth performance, carcase and meat quality traits. The dietary inclusion of full-fat silkworm meal in chicken diets enriched meat lipids with omega-3 fatty acids
Acquirer reputation in mergers and acquisitions
No full textReputation is a firm’s key intangible assets for shareholders’ value creation. Reputation building is a firm’s corporate strategy approach that is vital for the firm in order to sustain itself in this competitive global world. The influence of reputation on firm’s performance, decision making, employee retainment, cost reduction, and partner selection have been studied and documented by academics. Despite this, there have been insufficient studies on reputation and mergers and acquisitions (M&A) activity. M&As are an important corporate strategy that firms use to survive and expand their global market. In the UK, both the number and value of domestic and cross-border M&As has increased significantly over the years. Drawing from the emerging popularity of reputation and the increased amount of M&A activity by UK acquirers, this thesis investigates the relation between reputation and UK acquirer M&A activity.
This thesis focuses on three main issues: (1) the impact of reputation on acquirer cross-border M&A returns; (2) the relation between reputation and UK acquirer domestic and cross-border deal completion time; and (3) the relation between UK acquirer reputation and target’s ownership nature.
Firstly, event-time and calendar-time approaches are used to examine UK acquirer cross-border M&A returns. The result reveals a significant relation between reputation and acquirer M&A returns. The author finds high reputation acquirers earned significant cross-border event-time and calendar-time returns. Secondly, this study finds a significant positive relation between acquirer reputation and domestic and cross-border deal completion time. This result implies that a high reputation acquirer takes more time to complete a deal. Lastly, the author finds a high reputation acquirer is more likely to choose a public target over a private target in domestic and cross-border M&As. However, the author finds a mixed result for subsidiaries: a high reputation acquirer is more likely to choose a subsidiary for a cross-border M&A, and less likely to for a domestic M&A
The influence of pore pressure on fracture behaviour of Normal-Strength and High-Performance Concretes at high temperature
No full textExplosive spalling consists in the sudden separation of concrete layers or pieces from the surface exposed to fire, due to (a) stress caused by thermal gradients and external loads and (b) pore pressure rise induced by water vaporization. As regards the material properties, the phenomenon is affected by some meso- and micro-structural aspects mainly concerning the interaction during heating among cement paste, aggregate and fibre, thus influencing porosity and permeability variation at high temperature. Focusing on the effect of pore pressure in fracture behaviour of Normal-Strength and High-Performance Concretes, an experimental campaign has been planned, aimed at investigating the role played by the mix design. Nine concrete mixes have been studied considering three grades (fc ≥ 40, 60 and 90 MPa), three aggregate types (silico-calcareous, basalt and calcareous aggregates) and different fibre types and contents (monofilament or fibrillated polypropylene fibres). The experimental study, based on indirect tension tests performed under different levels of sustained pore pressure, clearly shows that the influence of pressure on concrete fracture response during heating strongly depends on mix design
