The purpose of this paper is to study the implementation of GNSS technique in aviation for recovery of aircraft’s position using Precise Point Positioning (PPP) method.

The aircraft’s coordinates in ellipsoidal frame were obtained based on GPS code and phase observations for PPP method. The numerical computations were executed in post-processing mode in the CSRS-PPP and magicPPP online services. The mathematical scheme of PPP method was development using indifference equations of Ionosphere-Free linear combination. In the experiment, airborne test using Cessna 172 aircraft on June 01, 2010 in the military airport in Deblin was realized. The aircraft’s position was determined using data from GNSS receiver (Topcon HiperPro with interval of 1 s).

In this paper, the accuracy of aircraft’s position is better than 0.07 m for CSRS-PPP service and better than 0.27 m for magicPPP service. In case of the Mean Radial Spherical Error parameter, the average value for CSRS-PPP service equals to 0.01 m, whereas for magicPPP, it is about 0.38 m. The values of vertical coordinate of Cessna 172 aircraft were also checked with results of Real Time Kinematic–On The Fly technique.

In this paper, the analysis of aircraft positioning is focused on the application of the PPP method in post-processing mode. In near real time, the PPP method still has limitations, especially in the area of ambiguity resolution and also instrumental biases (e.g. Narrow Lane Hardware Delays).

The PPP method can be applied in aviation in post-processing mode for verification of true aircraft coordinates and elimination of blunder errors from adjustment processing of GNSS observations. The Zenith Wet Delay term as a product of troposphere delay and receiver clock bias as a product of precise time transfer can be obtained in the PPP method.

The paper presents that the PPP method is an alternative solution for the recovery of aircraft’s position in aviation, and this method can be also applied in the positioning of aircraft based on GLONASS or GPS/GLONASS data.

Research has demonstrated that employees desire to be shown appreciation in various ways. The five languages of appreciation provide a model for exploring these differences. This study aims to explore whether individuals who speak different languages (and are from various cultures) differ in how they prefer to be shown appreciation.

The Motivating By Appreciation Inventory (MBAI) is an online tool that assesses each person’s preferences in how they desire to be shown appreciation at work. Initially developed in English, the MBAI has been translated into seven additional languages. Over 2,200 employees took the MBAI in their preferred spoken language: Mandarin (Chinese), Danish, French (Canadian), Portuguese (Brazilian), Spanish (Latin American), Thai and Turkish. The frequency of each group’s preferred appreciation languages was analyzed to determine similarities and differences across the languages spoken.

Given the non-normal distribution of the data, the Kruskal–Wallis test found that there was a significant difference in preferences for participants’ primary appreciation language across the seven groups of various spoken languages. One key theme was that words of affirmation were most frequently chosen by five of the seven language groups, whereas employees from Thailand and Turkey chose acts of service most frequently. Additionally, tangible gifts were the least frequently chosen appreciation language by all groups, and at rates below their US counterparts. In three of the languages, quality time was preferred significantly less compared with the other languages.

Some of the groups’ findings (Portuguese, Thai) may be impacted by a confounding variable of the type of work setting (manufacturing) in which the employees worked – in comparison to office-based work settings.

One theme was, in comparison to other ways of receiving appreciation, tangible gifts are not highly valued by most employees across all language groups. Therefore, organizations using gifts as the primary way to communicate appreciation to employees may be wasting a lot of money. Similar to English-speaking employees, five of the seven language groups chose words as their preferred appreciation language. A wide range exists, however, across language groups with regards to the proportion who desire words, quality time or acts of service. Multicultural organizations should pay attention to employee preferences, lest they waste time and energy on undesired actions.

To the best of the author’s knowledge, this is the first study that has examined the preferences of how employees like to be shown appreciation across seven different language groups.

In July 2021, the European Commission has proposed a set of conjunct initiatives to reform the antimoney laundering/countering the financing of terrorism (AML/CFT) regulatory regime in Europe with the main aims to (i) harmonize the AML/CFT regulation and (ii) centralize the authority to a higher degree at European Union (EU) level. This paper aims to assess the reform in light of the EU subsidiarity principle.

The paper uses a benchmark approach to compare the proposed EU money laundering reform against Article 5(3) of the Treaty on the Functioning of the European Union.

The paper confirms that more centralized decision-making at EU level in this policy area is justified, mainly because (i) the policy area is not an area where the EU has exclusive competence, (ii) EU centralized action is necessary and (iii) it also adds value, for instance, for level playing field and efficiency considerations as long as local information advantage will not be lost. As such, the subsidiarity principle can be applied and is an adequate tool to legitimize EU centralized action in the field of money laundering combat.

As the EU AML regulatory reform has not yet been sufficiently discussed in light of the subsidiarity principle, the article is of innovative nature.

In this paper, the philosophy of John Rawls, known as “Justice as Fairness,” is discussed. This philosophy examines the responsibilities social actors hold toward their societal organizations. From an Islamic perspective, justice is pivotal in safeguarding collective interests, aligning with Rawls' conviction that just societies nurture happiness and foster well-being across various life aspects. To achieve customer welfare, our viewpoint underscores the importance of justice in reflecting on consumer well-being from both Rawls’ theory and Islamic perspectives.

We adopt a conceptual approach where secular views of Rawls’ “Theory of Justice” are merged with the Islamic view, resulting in novel insights regarding the hermeneutics involved in the notion of justice and the preservation of consumer well-being.

Our analysis reveals that John Rawls' “A Theory of Justice” aligns with the Islamic perspective in several respects yet diverges in others, notably in the concepts of pre-creation consciousness and divine guidance. These distinctions are emphasized in our paper.

Our paper presents a perspective on justice founded on the concepts of the “Original Position” and the “Veil of Ignorance.” The commentary explores consumer well-being by integrating Rawls' principles with an analysis that elucidates the role justice plays in enhancing societal welfare.
