Abstract: This paper presents an approach for the classification of
an unstructured format description for identification of file formats.
The main contribution of this work is the employment of data mining
techniques to support file format selection with just the unstructured
text description that comprises the most important format features for
a particular organisation. Subsequently, the file format indentification
method employs file format classifier and associated configurations to
support digital preservation experts with an estimation of required file
format. Our goal is to make use of a format specification knowledge
base aggregated from a different Web sources in order to select file
format for a particular institution. Using the naive Bayes method,
the decision support system recommends to an expert, the file format
for his institution. The proposed methods facilitate the selection of
file format and the quality of a digital preservation process. The
presented approach is meant to facilitate decision making for the
preservation of digital content in libraries and archives using domain
expert knowledge and specifications of file formats. To facilitate
decision-making, the aggregated information about the file formats is
presented as a file format vocabulary that comprises most common
terms that are characteristic for all researched formats. The goal is to
suggest a particular file format based on this vocabulary for analysis
by an expert. The sample file format calculation and the calculation
results including probabilities are presented in the evaluation section.
Abstract: By the evolvement in technology, the way of
expressing opinions switched direction to the digital world. The
domain of politics, as one of the hottest topics of opinion mining
research, merged together with the behavior analysis for affiliation
determination in texts, which constitutes the subject of this paper.
This study aims to classify the text in news/blogs either as
Republican or Democrat with the minimum number of features. As
an initial set, 68 features which 64 were constituted by Linguistic
Inquiry and Word Count (LIWC) features were tested against 14
benchmark classification algorithms. In the later experiments, the
dimensions of the feature vector reduced based on the 7 feature
selection algorithms. The results show that the “Decision Tree”,
“Rule Induction” and “M5 Rule” classifiers when used with “SVM”
and “IGR” feature selection algorithms performed the best up to
82.5% accuracy on a given dataset. Further tests on a single feature
and the linguistic based feature sets showed the similar results. The
feature “Function”, as an aggregate feature of the linguistic category,
was found as the most differentiating feature among the 68 features
with the accuracy of 81% in classifying articles either as Republican
or Democrat.
Abstract: This paper shows the connection between emoticons and politeness in written computer-mediated communication. It studies if there are some differences in the use of emoticon between Czech and English written tweets. The assumptions about the use of emoticons were based on the use of greetings and thanks in real, faceto-face situations. The first assumption, that welcome greeting phrase would be accompanied by positive emoticon, was correct. But for the farewell greeting are both positive and negative emoticons possible. The results show lower frequency of negative emoticons in this context. There were also quite often found both positive and negative emoticon in the same tweet. The expression of gratitude is associated with positive emotions. The results show that emoticons accompany polite phrases of greeting and thanks very often both in Czech and English. The use of emoticons with studied polite phrases shows that emoticons have become an integral part of these phrases.

Abstract: This study will examine how the therapeutic factors
(therapeutic catharsis-seeking and game-efficacy of the game player)
and self-construal factors (independent and interdependent
self-construal of the game player) as well as social capital factors
(bonding and bridging social capital of the game player) affect
aggression in the game. Results show that both therapeutic
catharsis-seeking and game self-efficacy are particularly important to
the players since they cause the game players’ aggressive tendencies to
be greatly diminished. Independent self-construal reduces the level of
the players’ aggression. Interestingly enough, the bonding social
capital enhances the level of the players’ aggression, while individuals
with bridging social capital did not show any significant effects. The
results and implications will be discussed herein.
Abstract: Exploration and exploitation capabilities are both
important within Operations as means for improvement when
managed separately, and for establishing dynamic improvement
capabilities when combined in balance. However, it is unclear what
exploration and exploitation capabilities imply in improvement and
development work within an Operations context. So, in order to
better understand how to develop exploration and exploitation
capabilities within Operations, the main characteristics of these
constructs needs to be identified and further understood. Thus, the
objective of this research is to increase the understanding about
exploitation and exploration characteristics, to concretize what they
translates to within the context of improvement and development
work in an Operations unit, and to identify practical challenges. A
literature review and a case study are presented. In the literature
review, different interpretations of exploration and exploitation are
portrayed, key characteristics have been identified, and a deepened
understanding of exploration and exploitation characteristics is
described. The case in the study is an Operations unit, and the aim is
to explore to what extent and in what ways exploration and
exploitation activities are part of the improvement structures and
processes. The contribution includes an identification of key
characteristics of exploitation and exploration, as well as an
interpretation of the constructs. Further, some practical challenges are
identified. For instance, exploration activities tend to be given low
priority, both in daily work as in the manufacturing strategy. Also,
the overall understanding about the concepts of exploitation and
exploration (or any similar aspect of dynamic improvement
capabilities) is very low.
Abstract: This paper participates in giving new vision and
explains the learning and acquisition processes of English language
by analyzing a certain context. Five important factors in English
language acquisition and learning are discussed and suitable solutions
are provided. The factors are compared with the learners' linguistic
background at Bisha College of Technology BCT attempting to link
the issues faced by students and the research done on similar
situations. These factors are phonology, age of acquisition,
motivation, psychology and courses of English. These factors are
very important; because they interfere and affect specific learning
processes at BCT context and general English learning situations.
Abstract: Nowadays, the main goal for modern horticultural
production is an increase the quality. In recent years, the use of
organic fertilizers or biostimulants that can be applied in agriculture
to improve quali-quantitative crop yields has encountered increasing
interest. Biostimulants are gaining importance also for their possible
use in organic and sustainable agriculture, to avoid excessive
fertilizer applications. Consecutive experimental trials were carried
out in the Apulia region (southern Italy) on three herbaceous crops
(cauliflower, pepper, fennel) grown in pots under conventional and
organic fertilization systems without and with biostimulants. The aim
was to determine the effects of three biostimulants (Siapton®10L,
Micotech L, Lysodin Alga-Fert) on quali-quantitative yield
characteristics. At harvest, the quali-quantitative yield characteristics
of each crop were determined. All of the experimental data were
subjected to analysis of variance (ANOVA), and when significant
effects were detected, the means were compared using Tukey’s tests.
These data show large differences in these yield characteristics
between conventional and organic crops, particularly highlighting
higher yields for the conventional crops, while variable results were
generally observed when the biostimulants were applied. In this
context, there were no effects of the biostimulants on the quantitative
yield, whereas there were low positive effects on the qualitative
characteristics, as related to higher dry matter content of cauliflower,
and higher soluble solids content of pepper. Moreover, there were
evident positive effects of the biostimulants with fennel, due to the
lower nitrate content. These latter data are in line with most of the
published literature obtained for other herbaceous crops.
Abstract: Because blueberries are worldwide recognized as a
good source of beneficial components, their consumption has
increased in the past decades, and so have the scientific works about
their properties. Hence, this work was undertaken to evaluate the
effect of some production and conservation factors on the properties
of blueberries from cultivar Bluecrop. The physical and chemical
analyses were done according to established methodologies and then
all data was treated using software SPSS for assessment of the
possible differences among the factors investigated and/or the
correlations between the variables at study. The results showed that
location of production influenced some of the berries properties
(caliber, sugars, antioxidant activity, color and texture) and that the
age of the bushes was correlated with moisture, sugars and acidity, as
well as lightness. On the other hand, altitude of the farm only was
correlated to sugar content. With regards to conservation, it
influenced only anthocyanins content and DPPH antioxidant activity.
Finally, the type of extract and the order of extraction had a
pronounced influence on all the phenolic properties evaluated.
Abstract: The objective of this paper is to present the process of
change in management accounting in Romania, a former communist
country from Eastern Europe. In order to explain this process, we used
the contingency and institutional theories. We focused on the
following directions: the presentation of the scientific context and
motivation of this research and the case study. We presented the state
of the art in the process of change in the management accounting from
the international and national perspective. We also described the
evolution of management accounting in Romania in the context of
economic and political changes. An important moment was the fall of
communism in 1989. This represents a starting point for a new
economic environment and for new management accounting.
Accordingly, we developed a case study which presented this
evolution. The conclusion of our research was that the changes in the
management accounting system of the company analysed occurred in
the same time with the institutionalisation of some elements (e.g.
degree of competition, training and competencies in management
accounting). The management accounting system was modelled by the
contingencies specific to this company (e.g. environment, industry,
strategy).
Abstract: Any variation in environmental characteristics of
geomorphosites would lead to destabilisation of their geotouristic
values all around the planet. The Urmia lake, with an area of
approximately 5,500 km2 and a catchment area of 51,876 km2, and to
which various reasons over time, especially in the last fifty years
have seen a sharp decline and have decreased by about 93 % in two
recent decades. These variations are not only driving significant
changes in the morphology and ecology of the present lake
landscape, but at the same time are shaping newly formed
morphologies, which vanished some valuable geomorphosites or
develop into smaller geomorphosites with significant value from a
scientific and cultural point of view. This paper analyses and
discusses features and evolution in several representative coastal and
island geomorphosites. For this purpose, a total of 23 geomorphosites
were studied in two data series (1963 and 2015) and the respective
data were compared and analysed. The results showed, the total loss
in geomorphosites area in a half century amounted to a loss of more
than 90% of the valuable geomorphosites. Moreover, the comparison
between the mean yearly value of coastal area lost over the entire
period and the yearly average calculated for the shorter period (1998-
2014) clearly indicates a pattern of acceleration. This acceleration in
the rate of reduction in lake area was seen in most of the southern
half of the lake. In the region as well, the general water-level falling
is not only causing the loss of a significant water resource, which is
followed by major impact on regional ecosystems, but is also driving
the most marked recent (last century) changes in the geotouristic
landscapes. In fact, the disappearance of geomorphosites means the
loss of tourism phenomenon. In this context attention must be paid to
the question of conservation. The action needed to safeguard
geomorphosites includes: 1) Preventive action, 2) Corrective action,
and 3) Sharing knowledge.
Abstract: This article is to introduce the meaning and form of
social quality moving process as indicated by members of two suburb
communities with different social and cultural contexts. The form of
social quality moving process is very significant for the community
and social development, because it will make the people living
together with sustainable happiness.
This is a qualitative study involving 30 key-informants from two
suburb communities. Data were collected though key-informant
interviews, and analyzed using logical content description and
descriptive statistics.
This research found that on the social quality component, the
people in both communities stressed the procedure for social qualitymaking.
This includes the generousness, sharing and assisting among
people in the communities. These practices helped making people to
live together with sustainable happiness. Living as a family or appear
to be a family is the major social characteristic of these two
communities.
This research also found that form of social quality’s moving
process of both communities stress relation of human and nature;
“nature overpower humans” paradigm and influence of religious
doctrine that emphasizes relations among humans. Both criteria make
the form of social’s moving process simple, adaptive to nature and
caring for opinion sharing and understanding among each other
before action. This form of social quality’s moving process is
composed of 4 steps; (1) awareness building, (2) motivation to
change, (3) participation from every party which is concerned (4)
self-reliance.
Abstract: The main purpose of this study was to figure out
employees’ attitudes toward the new performance appraisal program
and to examine whether three different types of appraisal processes
differentially affected job satisfaction and employee engagement. The
second purpose of this study was to investigate the relationship
between performance appraisal reform, job satisfaction, and employee
engagement. A large polyester and textile corporation had 2046
non-operational employees in February 2014. The valid participants
were 1474 (72.04%) in this study. Data analysis included descriptive
statistics, one-way ANOVA, one-way MANOVA, Pearson correlation,
Content Validity Index, the exploratory factor analysis, and reliability
analysis. The general results showed that employees who received the
new performance appraisal program evaluated the program more
positively and showed more job satisfaction than those who did not. In
particular, the implementation effects of this new performance
appraisal program were most highly rated by employees who used the
KPI to rate their job performance. Moreover, employees’ attitudes
toward the new performance appraisal program were positively related
to their job satisfaction and employee engagement. Lastly, most
employees regarded themselves as engaged workers. To sum up, the
HR department of this company has made an effective contribution to
performance appraisal reforms.
Abstract: In educational technology, the idea of innovation is
usually tethered to contemporary technological inventions and
emerging technologies. Yet, using long-known technologies in ways
that are pedagogically or experimentially new can reposition them as
emerging educational technologies. In this study we explore how a
subtle pivot in pedagogical thinking led to an innovative education
technology. We describe the design and implementation of an online
writing tool that scaffolds students in the evaluation of their own
informational texts. We think about how pathways to innovation can
emerge from pivots, namely a leveraging of longstanding practices in
novel ways has the potential to cultivate new opportunities for
learning. We first unpack Infowriter in terms of its design, then we
describe some results of a study in which we implemented an
intervention which included our designed application.
Abstract: While emerging technologies continue to emerge,
research into their use in learning contexts often focuses on a subset
of educational practices and ways of using technologies. In this study
we begin to explore the extent to which educational designs are
influenced by larger societal and education-related factors not usually
explicitly considered when designing or identifying technology-supported
education experiences for research study. We examine
patterns within and between factors via a content analysis across ten
years and 19 different journals of published peer-reviewed research
on technology-supported writing. Our findings have implications for
how researchers, designers, and educators approach technology-supported
educational design within and beyond the field of writing
and literacy.
Abstract: Super steel materials play a vital role in the
construction and fabrication of structural, piping and pipeline
components. In assuring the integrity of onshore and offshore
operating systems, they enable life cycle costs to be minimized. In
this context, Duplex stainless steel (DSS) material related welding on
constructions and fabrications plays a significant role in maintaining
and assuring integrity at an optimal expenditure over the life cycle of
production and process systems as well as associated structures. In
DSS welding, factors such as gap geometry, shielding gas supply
rate, welding current, and type of the welding process are vital to the
final joint performance. Hence, an experimental investigation has
been performed using an engineering robust design approach
(ERDA) to investigate the optimal settings that generate optimal
super DSS (i.e. UNS S32750) joint performance. This manuscript
illustrates the mathematical approach and experimental design,
optimal parameter settings and results of the verification experiment.
Abstract: Non-crimp 3D orthogonal fabric composite is one of
the textile-based composite materials that are rapidly developing
light-weight engineering materials. The present paper focuses on
geometric and micromechanical modeling of non-crimp 3D
orthogonal carbon fabric and composites reinforced with it for
aerospace applications. In this research meso-finite element (FE)
modeling employs for stress analysis in different load conditions.
Since mechanical testing of expensive textile carbon composites with
specific application isn't affordable, simulation composite in a virtual
environment is a helpful way to investigate its mechanical properties
in different conditions.
Abstract: Fabric textures are very common in our daily life.
However, the representation of fabric textures has never been explored
from neuroscience view. Theoretical studies suggest that primary
visual cortex (V1) uses a sparse code to efficiently represent natural
images. However, how the simple cells in V1 encode the artificial
textures is still a mystery. So, here we will take fabric texture as
stimulus to study the response of independent component analysis that
is established to model the receptive field of simple cells in V1. We
choose 140 types of fabrics to get the classical fabric textures as
materials. Experiment results indicate that the receptive fields of
simple cells have obvious selectivity in orientation, frequency and
phase when drifting gratings are used to determine their tuning
properties. Additionally, the distribution of optimal orientation and
frequency shows that the patch size selected from each original fabric
image has a significant effect on the frequency selectivity.

and present.
Abstract: Due to the continuous increment of the load demand,
identification of weaker buses, improvement of voltage profile and
power losses in the context of the voltage stability problems has
become one of the major concerns for the larger, complex,
interconnected power systems. The objective of this paper is to
review the impact of Flexible AC Transmission System (FACTS)
controller in Wind generators connected electrical network for
maintaining voltage stability. Wind energy could be the growing
renewable energy due to several advantages. The influence of wind
generators on power quality is a significant issue; non uniform power
production causes variations in system voltage and frequency.
Therefore, wind farm requires high reactive power compensation; the
advances in high power semiconducting devices have led to the
development of FACTS. The FACTS devices such as for example
SVC inject reactive power into the system which helps in maintaining
a better voltage profile. The performance is evaluated on an IEEE 14
bus system, two wind generators are connected at low voltage buses
to meet the increased load demand and SVC devices are integrated at
the buses with wind generators to keep voltage stability. Power
flows, nodal voltage magnitudes and angles of the power network are
obtained by iterative solutions using MIPOWER.
