A Critical Review Of Post-Secondary Education Writing During A 21st Century Education Revolution
Educational materials are effective instruments which provide information and report new discoveries uncovered by researchers in specific areas of academia. Higher education, like other education institutions, rely on instructional materials to inform its practice of educating adult learners. In post-secondary education, developmental English programs are tasked with meeting the needs of dynamic populations, thus there is a continuous need for research in this area to support its changing landscape. However, the majority of scholarly thought in this area centers on K-12 reading and writing. This paucity presents a phenomenon to the post-secondary community. This research study uses a qualitative content analysis to examine peer-reviewed journals from 2003-2017, developmental online websites, and a government issued document directed toward reforming post-secondary developmental education programs. These highly relevant sources aid educators in discovering informational support to apply best practices for student success. Developmental education serves the purpose of addressing literacy gaps for students transitioning to college-level work. The findings here illuminate the dearth of material offered to developmental educators. This study suggests the field of literacy research is fragmented and highlights an apparent blind spot in scholarly literature with regard to English writing instruction. This poses a quandary for post-secondary literacy researchers in the 21st century and establishes the necessity for the literacy research community to commit future scholarship toward equipping college educators teaching writing instruction to underprepared adult learners
Design, Modelling and Analysis of Satcoms for UAV operations
Η ανάγκη για άμεση συνεισφορά, απόκριση και ακρίβεια των αποτελεσμάτων οδήγησε στην είσοδο των drones και ιδιαίτερα των μη επανδρωμένων εναέριων οχημάτων (UAV) ως νέα τεχνολογικά οχήματα. Ωστόσο, η ενσωμάτωση ενός τόσο κολοσσιαίου τεχνολογικού αποκτήματος δεν είναι καθόλου εύκολη υπόθεση. Πολλές απαιτήσεις εμφανίζονται σε διάφορους τομείς όπως τηλεπικοινωνίες, προβλήματα ωφέλιμου φορτίου που πρέπει να φέρει το UAV και σχέδια λειτουργίας, απαιτήσεις που πρέπει να πληρούνται για την αποφυγή προβλημάτων ασφάλειας, αποφυγή σύγκρουσης, ασταθείς συνδέσεις και άλλα.
Σκοπός της παρούσας διπλωματικής εργασίας είναι να μελετήσει όσο το δυνατόν καλύτερα και αποτελεσματικότερα τη συμβολή των δορυφορικών επικοινωνιών στην επίτευξη αξιόπιστων και ανθεκτικών επιχειρήσεων Μη Επανδρωμένων Αεροσκαφών (UAV). Θα παρουσιαστεί μια ανάλυση τριών επιπέδων που θα αφορά τον Σχεδιασμό, τη Μοντελοποίηση και την Ανάλυση δορυφορικών επικοινωνιών σε συνδυασμό με λειτουργίες UAV με τρόπο που η αποτελεσματικότητα της ζεύξης θα είναι μέγιστη εφικτή. Σε τελική ανάλυση, θα πραγματοποιηθεί ένα πείραμα που θα συζητηθούν τα αποτελέσματα και οι παράμετροι που χρησιμοποιούνται προκειμένου να υπολογιστεί η αποτελεσματικότητα του προϋπολογισμού των ζεύξεων.
Είναι σημαντικό να γνωρίζουμε ότι οι κυψελοειδείς επικοινωνίες έχουν παίξει μέχρι στιγμής τον πιο σημαντικό και ακριβή ρόλο τόσο στις επίγειες όσο και στις αεροπορικές επικοινωνίες. Αυτό πρόκειται να αλλάξει καθώς οι δορυφόροι υπόσχονται χαρακτηριστικά που δεν μπορούν να ανταγωνιστούν τα επίγεια δίκτυα, με αποτέλεσμα την ενοποίηση των UAV με τις δορυφορικές επικοινωνίες. Ωστόσο, τα πράγματα είναι ασαφή και οι κίνδυνοι που ενέχουν είτε από την άποψη των προσωπικών δεδομένων είτε από την ασφάλεια και την υγεία μπορούν να λειτουργήσουν ως εμπόδιο στην ανάπτυξη και την αναβάθμιση των επικοινωνιών.The need for immediate contribution, response, and accuracy of results has led to the
entry of drones and especially Unmanned Aerial Vehicles (UAVs) as new technological
vehicles. However, the integration of such a colossal technological acquisition is by no
means an easy task. Many requirements appear in various areas such as
telecommunications, payload problems that the UAV must carry, and operations plans,
requirements that must be met to avoid safety issues, collision avoidance, unstable
connections, and so more.
The purpose of this thesis is to study as best as possible and most effectively the
contribution of satellite communications to achieve reliable and durable Unmanned Aerial
Vehicles (UAVs) operations. A three-level analysis will be presented which will concern
the Design, Modeling, and Analysis of satellite communications in combination with UAV
operations in a way where efficiency of the link will be maximum. After all, an experiment
will take place that results and parameters used will be discussed in order to compute the
efficiency of the link budget.
It is important to know that cellular communications have so far played the most important
and accurate role in both terrestrial and air communications. This is about to change as
satellites promise features that cannot compete with terrestrial networks, resulting in the
integration of UAVs with satellite communications. However, things are unclear, and the
risks posed either from the point of view of personal data or from safety and health can
act as an obstacle in developing and upgrading communications
WORK 2019
This paper discusses, how the increase of digital interactions in modern organizations enables and challenges the use of observation as a research method within the qualitative research realm in management and organization (MO) studies. As e.g. Akemu and Abdelnour (2018) point out, interaction taking place over digital technologies and platforms is gradually merging with face-to-face interactions in a growing extent, permeating social life in ways that often escape ocular observation. In contemporary work, digital interaction takes place through various technological interfaces, such as computers, software platforms, documents, blogs, and so on. These digital artifacts (see e.g. Kallinikos et al, 2013) offer researchers the possibility to either follow ex post record of informants’ interactions, or engage in the process of interaction in real time. Moreover, digital technologies allow us to follow organizational interaction taking place in multiple sites simultaneously (Czarniawska 2008). However, despite of the changes in work and its contexts, many MO researchers seem to relay on traditional face-to-face observations with research designs involving one single location. In addition, in MO literature, so far, very little attention has been paid to methodological considerations of observational research, in order to support research practice to grasp the complexities fueled by virtuality and the use of technological advancements within modern work life.It can be stated, that irrespective of the context of study, there exist similar issues to be solved for observational research. Researchers need to reflect access, issues of trust and rapport with participants, the degree of involvement, or ways to specify the case or process being studied. Yet, as Garcia and her colleagues (2009) point out, a new set of skills is required to observe and interact with research participants in computer-mediated work communities. Observation focusing on mainly one physical setting and face-to-face interaction only, is becoming inadequate means to capture the richness of contemporary work. For example, the seemingly simple observation of people working on their computers or smart phones may lead to misleading conclusions, as some may be playing an online game, some chatting with a friend or trading shares, or some writing a novel. This challenges researchers’ ability to grasp and describe the quality of interaction taking place. Moreover, in order to observe online work, one cannot rely solely on the interpersonal skills of co-presence with the research participants. The issues of research ethics, such as the lack of physical presence and opportunities for anonymity for researcher, as well as the needs for participant privacy and confidentiality may differ from face-to-face contexts. Consequently, it is argued in this paper, that qualitative researchers applying observation within MO, need to adjust their research strategies and techniques to meet the characteristics of contemporary interaction within computer-mediated communication (see also e.g. Akemu & Abdelnour 2018).The paper builds on the findings of a narrative literature review (e.g. Bryman & Bell 2011), with the purpose of generating understanding of the topic base on the existing literature. We discuss the specific nature of the computer mediated communication, and the possibilities and challenges it poses for the observational researcher, either separately, or combined with other research approaches, such as ethnography. It is further argued, that observational research combined with virtuality of work, calls for and opens up new possibilities even to those MO researchers, who have previously mainly built on other methods, such as interviews or historical archival data. We conclude by discussing how the computer-mediated communication of modern workplaces not only has impact on observing online work, but simultaneously on interaction taking place offline.</div
Assuming Data Integrity and Empirical Evidence to The Contrary
Background: Not all respondents to surveys apply their minds or understand
the posed questions, and as such provide answers which lack coherence, and
this threatens the integrity of the research. Casual inspection and limited
research of the 10-item Big Five Inventory (BFI-10), included in the dataset of
the World Values Survey (WVS), suggested that random responses may be
common.
Objective: To specify the percentage of cases in the BRI-10 which include
incoherent or contradictory responses and to test the extent to which the
removal of these cases will improve the quality of the dataset.
Method: The WVS data on the BFI-10, measuring the Big Five Personality (B5P), in South Africa (N=3 531), was used. Incoherent or contradictory responses were removed. Then the cases from the cleaned-up dataset were analysed for their theoretical validity.
Results: Only 1 612 (45.7%) cases were identified as not including incoherent
or contradictory responses. The cleaned-up data did not mirror the B5P- structure, as was envisaged. The test for common method bias was negative. Conclusion: In most cases the responses were incoherent. Cleaning up the data did not improve the psychometric properties of the BFI-10. This raises concerns about the quality of the WVS data, the BFI-10, and the universality of B5P-theory. Given these results, it would be unwise to use the BFI-10 in South Africa. Researchers are alerted to do a proper assessment of the
psychometric properties of instruments before they use it, particularly in a
cross-cultural setting
Air Traffic Management Abbreviation Compendium
As in all fields of work, an unmanageable number of abbreviations are used today in aviation for terms, definitions, commands, standards and technical descriptions. This applies in general to the areas of aeronautical communication, navigation and surveillance, cockpit and air traffic control working positions, passenger and cargo transport, and all other areas of flight planning, organization and guidance. In addition, many abbreviations are used more than once or have different meanings in different languages.
In order to obtain an overview of the most common abbreviations used in air traffic management, organizations like EUROCONTROL, FAA, DWD and DLR have published lists of abbreviations in the past, which have also been enclosed in this document. In addition, abbreviations from some larger international projects related to aviation have been included to provide users with a directory as complete as possible. This means that the second edition of the Air Traffic Management Abbreviation Compendium includes now around 16,500 abbreviations and acronyms from the field of aviation

Leading Towards Voice and Innovation: The Role of Psychological Contract
Background: Empirical evidence generally suggests that psychological
contract breach (PCB) leads to negative outcomes. However, some literature
argues that, occasionally, PCB leads to positive outcomes.
Aim: To empirically determine when these positive outcomes occur, focusing
on the role of psychological contract (PC) and leadership style (LS), and
outcomes such as employ voice (EV) and innovative work behaviour (IWB).
Method: A cross-sectional survey design was adopted, using reputable
questionnaires on PC, PCB, EV, IWB, and leadership styles. Correlation
analyses were used to test direct links within the model, while regression
analyses were used to test for the moderation effects.
Results: Data with acceptable psychometric properties were collected from 11
organisations (N=620). The results revealed that PCB does not lead to
substantial changes in IWB. PCB correlated positively with prohibitive EV, but did not influence promotive EV, which was a significant driver of IWB. Leadership styles were weak predictors of EV and IWB, and LS only partially moderated the PCB-EV relationship. Conclusion: PCB did not lead to positive outcomes. Neither did LS influencing the relationships between PCB and EV or IWB. Further, LS only partially influenced the relationships between variables, and not in a manner which positively influence IWB
