TL;DR: In this paper, the authors have used abductive content analysis to analyse the motivational factors and experiences of Finnish investigative journalist Jessikka Aro in relation to her exploratory journey in exposing pro-Russia trolling in Finland.
Abstract: Today’s colliding world views between West and East have resulted in phenomena such as the war in Ukraine and pro-Russia trolling in Finland. In this context, social media, understood here as a synonym for cyber, is ‘contaminated’ and has turned out to be a chaotic virtual environment that facilitates the dissemination of all kinds of propagandist lies and pseudo-truths in addition to fact-based discussion. This article leans theoretically on Self-Determination Theory (SDT) and the Leader–Member Exchange (LMX) Theory of Leadership. The main argument of SDT is that human beings have an intrinsic need to explore and satisfy their curiosity. The LMX Theory of Leadership complements SDT by focusing on the relationship between leaders and their subordinates, which, for the purposes of this article, concerns the relationship between an explorer and their followers. The article poses the question: What motivates some individuals to challenge existing oppressive world views and injustices regardless of the fact that they know they will be heavily criticised as a result of their explorative journey? In addressing this question, the authors have used abductive content analysis to analyse the motivational factors and experiences of Finnish investigative journalist Jessikka Aro in relation to her exploratory journey in exposing pro-Russia trolling in Finland. The key arguments are as follows: Jessikka Aro’s main motivation for exposing pro-Russia trolling in Finland stemmed from her professional curiosity towards Russia and Russian propaganda. She did not intend to become any kind of leader or champion (‘Jedi’) for her followers (‘Starmen’) and was actually embarrassed by such labels, even if her followers might have regarded her as such. She has continued her exploratory journey in exposing pro-Russia trolling in Finland because she has been supported by her significant others (working community, family and closest friends) and generalised others (social media followers), and has managed to create new human networks, which have also encouraged her to stay on the same track. Aro contends that after publishing a number of articles and giving interviews and lectures on pro-Russia trolling in Finland, many Finns have begun to talk more openly not only about Russian propagandist trolling and pro-Russia trolling networks but also about Russia’s acts of aggression in violation of international agreements.

TL;DR: In this article, the dilemma faced by the Sultan and how he maneuvered the crisis is discussed through a thorough content analysis of available literature, and it is found that Sultan Ahmad was very intelligent, wise and diplomatic in preserving peace and harmony amongst the local people and could still be in the good books of the British.
Abstract: British colonization over the state of Pahang in the late 19th century resulted in an incident which is known as the Pahang uprising. Introduction of several new systems by the colonialists had caused chaos. The locals, mostly the dignitaries or chieftains who were in close relationship with the Sultan, rebelled against these new enforcements. On the other hand, the Sultan who had to maintain his status quo with the British was in a dilemma. This article looks at the dilemma faced by the ruler and how he maneuvered the crisis; through thorough content analysis of available literature. It is found that Sultan Ahmad was very intelligent, wise and diplomatic in preserving peace and harmony amongst the local people and could still be in the good books of the British. His strategies united the rebels yet he maintained his sovereignty and remained unthreatened by the British.

TL;DR: In this paper, a simple adaptive antenna array adaptation algorithm that operates in the absence of the reference signal is proposed and its successful testing was carried out under assumptions that the useful signal in the adaptive antenna arrays does not have an impact on the adaptation process, which is valid for radar applications with short duration useful signals but not necessarily applicable for telecommunication systems with continuous ones.
Abstract: Signal processing algorithms in adaptive antenna arrays are analyzed with respect to their application in mobile telecommunication systems. It is established that both in literature and in practice insufficient attention is paid to search for and design of such simple adaptation algorithms that do not require presence of the reference signal. A simple algorithm of antenna array adaptation was earlier deduced that operates in the absence of the reference signal. Its successful testing was carried out under assumptions that the useful signal in the adaptive antenna array does not have an impact on the adaptation process. This assumption is valid for radar applications with short duration useful signals but not necessarily applicable for telecommunication systems with continuous ones. To address these limitations, influences of the useful signal on the algorithm convergence parameters are studied. Computer simulation of adaptive antenna arrays with the designed algorithm with account of useful signal impact in different situations is performed. It is shown that with some adjustments of the constant that determines the adaptation step, the impact of continuous useful signals on the designed gradient algorithm convergence performance can be greatly mitigated.

Abstract: The study focused on the most critical issues like work overload and the fear of negative evaluation, and here we measured the impact of work overload and the fear of negative evaluation in addition resultantly occur the role of frustration on employees’ performance in Commercial Banks of Islamabad, Pakistan. An online and by hand floated questionnaires were distributed to the employees to obtain feedback. The target population for this study were Banks’ managerial and administrative employees. Based on the convenience sampling design, 240 employees from 35 banks were approached. 199 completely filled questionnaires were received out of 240 employees. The collected data was analyzed using Smart Partial Least Squares (PLS) Path Modelling Method and Statistical Package for Social Sciences (SPSS)” version 22 for analysis and the reliability test, for all items of each scale and satisfactory results were obtained. Results show that work overloads negatively influence employee performance. Similarly, fear of negative evaluation also creates an adverse impact on performance.

TL;DR: In this article, a method for the measurement, using small-angle X-ray scattering (SAXS), of the microfibril angle, (MFA) and the associated standard deviation for the cellulose micro-fibrils in the S2 layer of the cell walls of Acacia mangium wood is presented.
Abstract: Microfibril angle, (MFA) in hardwood is one of the key determinants of solid timber performance due to its strong influence on the stiffness, strength, shrinkage, swelling, thermal-dynamics mechanical properties and dimensional stability of wood.. A method is presented for the measurement, using small-angle X-ray scattering (SAXS), of the microfibril angle, (MFA) and the associated standard deviation for the cellulose microfibrils in the S2 layer of the cell walls of Acacia mangium wood. The length and orientation of the microfibrils of the cell walls in the irradiated volume of the thin samples are measured using SAXS and scanning electron microscope, (SEM). The undetermined parameters in the analysis are the MFA, (M) and the standard deviation (σФ) of the intensity distribution arising from the wandering of the fibril orientation about the mean value. Nine separate pairs of values are determined for nine different values of the angle of the incidence of the X-ray beam relative to the normal to the radial direction in the sample. The results show good agreement. The curve distribution of scattered intensity for the real cell wall structure is compared with that calculated with that assembly of rectangular cells with the same ratio of transverse to radial cell wall length. It is demonstrated that for β = 45°, the peaks in the curve intensity distribution for the real and the rectangular cells coincide. If this peak position is Ф45, Then the MFA can be determined from the relation M = tan-1 (tan Ф45 / cos 45°), which is precise for rectangular cells. . Here we shall present our results of the MFA in the cell wall with respect to its shape and structure as an important fast check and yet accurate towards the quality of wood, its uses and application.
