Abstract

Adults are independent learners and are expected to direct their own learning. Nowadays, there are many MOOC platforms preferred by adult learners. Many states have adapted to these developments and established an online learning platform in order to carry out the training and development activities of civil servants. The Presidency of the Republic of Türkiye Human Resources Office has established the Distance Learning Gate (DLG) platform in order to carry out educational activities. In this study, learning preferences of adult learners were determined in order to improve the relevant online learning environment and to structure appropriate trainings for public personnel. For this purpose, the training preferences of adult learners were determined according to their title groups and education levels. The participants of the research consisted of 4864 civil servants who received training from the DLG platform. According to the results, it was determined that adult learners preferred personal development training the most and professional development training in the last place. It is seen that the servants in the service title group that watched the most training in all categories according to the title groups. It is seen that the groups that received the least education are the senior manager and manager title group. On the other hand, it has been determined that the number of adult learners' training and the education categories differ according to the education level. According to the findings, it is seen that those who watched the most education are adults at the compulsory primary education level, while those who watched the least education are those who are at the graduate level. This research includes the first phase of a series of research and a design-based research. As a first step, the training preferences of adult learners were determined. In the next stage, a recommendation system will be integrated into the DLG platform based on the determined profiles.

Abstract

We present the first observations of seismic waves propagating through the core of Mars. These observations, made using seismic data collected by the InSight geophysical mission, have allowed us to construct the first seismically constrained models for the elastic properties of Mars' core. We observe core-transiting seismic phase SKS from two farside seismic events detected on Mars and measure the travel times of SKS relative to mantle traversing body waves. SKS travels through the core as a compressional wave, providing information about bulk modulus and density. We perform probabilistic inversions using the core-sensitive relative travel times together with gross geophysical data and travel times from other, more proximal, seismic events to seek the equation of state parameters that best describe the liquid iron-alloy core. Our inversions provide constraints on the velocities in Mars' core and are used to develop the first seismically based estimates of its composition. We show that models informed by our SKS data favor a somewhat smaller (median core radius = 1,780 to 1,810 km) and denser (core density = 6.2 to 6.3 g/cm3) core compared to previous estimates, with a P-wave velocity of 4.9 to 5.0 km/s at the core-mantle boundary, with the composition and structure of the mantle as a dominant source of uncertainty. We infer from our models that Mars' core contains a median of 20 to 22 wt% light alloying elements when we consider sulfur, oxygen, carbon, and hydrogen. These data can be used to inform models of planetary accretion, composition, and evolution.

Abstract

Determining the content type preferences of adult learners in online learning environments makes important contributions to presenting adaptive content to adults. In this research, content type preferences and interaction patterns of adults in online learning environments were determined. Video, interactive video, textual content, presentation, and video conference as content type and self-efficacy, self-learning, learner control, and motivation were handled. Adult learners' patterns between content type preferences and psycho-educational constructs were determined with Configural Frequency Analysis. Adults who have low level in each of the psycho-educational constructs prefer only one of the interactions such as video, presentation and video-conference. It was determined that adult learners, who have high level in each of the psycho-educational structures, preferred video-conference at a low level.

Abstract

NASA's InSight mission on Mars continues to record seismic data over 3 years after landing, and to date, over a thousand marsquakes have been identified. With only a single seismic station, the determination of the epicentral location is far more challenging than on Earth. The Marsquake Service (MQS) produces seismicity catalogues from data collected by InSight and provides distance and back azimuth estimates when these can be reliably determined - when both are available these are combined to provide a location. Currently, MQS do not assign a back azimuth to the vast majority of marsquakes. In this work we develop and apply a polarization analysis method to determine the back azimuth of seismic events from the polarization of observed P and S-wave arrivals. The method is first applied to synthetic marsquakes, and then calibrated using a set of well-located earthquakes that have been recorded in Tennant Creek, Australia. We find that the back azimuth is estimated reliably using our polarization method. The same approach is then used for a set of high quality marsquakes recorded up to October 2021. We are able to estimate back azimuths for 24 marsquakes, 16 of these without MQS back azimuths. We locate most events to the east of InSight, in the general region of Cerberus Fossae., Comment: 27 pages, 11 figures. Supplement 24 pages, 23 figures

Abstract

SEIS, the seismometer of the InSight mission, which landed on Mars on 26 November 2018, is monitoring the seismic activity of the planet. The goal of the Mars Structure Service (MSS) is to provide, as a mission product, the first average 1-D velocity model of Mars from the recorded InSight data. Prior to the mission, methodologies have been developed and tested to allow the location of the seismic events and estimation of the radial structure, using surface waves and body waves arrival times, and receiver functions. The paper describes these validation tests and compares the performance of the different algorithms to constrain the velocity model below the InSight station and estimate the 1-D average model over the great circle path between source and receiver. These tests were performed in the frame of a blind test, during which synthetic data were inverted. In order to propagate the data uncertainties on the output model distribution, Bayesian inversion techniques are mainly used. The limitations and strengths of the methods are assessed. The results show the potential of the MSS approach to retrieve the structure of the crust and underlying mantle. However, at this time, large quakes with clear surface waves have not yet been recorded by SEIS, which makes the estimation of the 1-D average seismic velocity model challenging. Additional locatable events, especially at large epicentral distances, and development of new techniques to fully investigate the data, will ultimately provide more constraints on the crust and mantle of Mars.

Abstract

Purpose: The aim of the current study is twofold. First, it investigates the relationship between mobbing and organizational identification (OI) as an organizational attitude. Second, it explores the moderating effect of perceived organizational support (POS) on the relationship between mobbing and organizational identification. We proposed that perceived organizational support acts as a moderator between mobbing and organizational identification. Research Methods: We used a cross-sectional design and data were gathered from employees working in a higher educational institution. The sample yielded 152 complete surveys, including 123 academics and 29 administrative staff. The questionnaire included measures of mobbing, perceived organizational support, and organizational identification. Findings: The results of the moderated regression analysis do not provide support for the moderating effect of perceived organizational support in the relationship between mobbing and organizational identification. However, the findings demonstrate that, rather than a moderating variable, perceived organizational support is positively associated with organizational identification. Implications for Research and Practice: The results of the current study highlight the effect of organizational support in increasing the organizational identification levels of employees to their organizations. It would be beneficial for future research to assess the moderator effect of other dispositional or situational variables on the proposed relationships. Moreover, future research might also investigate other work outcomes, such as intention to leave, job satisfaction, and job performance.

Abstract

The analysis of seismic events recorded by NASA's InSight seismometer remains challenging, given their commonly low magnitudes and large epicentral distances, and concurrently, strongly varying background noise. These factors collectively result in low signal-to-noise ratios (SNR) across most event recordings. We use a deep learning denoising approach to mitigate the noise contamination, aiming to enhance the data analysis and the seismic event catalogue. Our systematic tests demonstrate that denoising performs comparable to fine-tuned bandpass filtering at high SNRs, but clearly outperforms it at low SNRs with respect to accurate waveform and amplitude retrieval, as well as onset picking. We review the denoised waveform data of all 98 low-frequency events in the Marsquake Service catalogue version 14, and improve their location when possible through the identification of phase picks and backazimuths, while ensuring consistency with the raw data. We demonstrate that several event waveforms can be explained by marsquake doublets—two similarly strong quakes in spatio-temporal proximity that result in overlapping waveforms at InSight—and we locate them in Cerberus Fossae (CF). Additionally, we identify and investigate aftershocks and an event sequence consisting of numerous relatively high magnitude marsquakes occurring within hours at epicentral distances beyond CF. As a result of this review and interpretation, we extend the catalogue in event numbers (⁠|$+$| 8 per cent), in events with epicentral distances and magnitudes (⁠|$+$| 50 per cent), and events with backazimuths and a resulting full locations (⁠|$+$| 46 per cent), leading to a more comprehensive description of Martian seismicity.

Abstract

We report observations of Rayleigh waves that orbit around Mars up to three times following the S1222a marsquake. Averaging these signals, we find the largest amplitude signals at 30 and 85 s central period, propagating with distinctly different group velocities of 2.9 and 3.8 km/s, respectively. The group velocities constraining the average crustal thickness beneath the great circle path rule out the majority of previous crustal models of Mars that have a >200 kg/m(3) density contrast across the equatorial dichotomy between northern lowlands and southern highlands. We find that the thickness of the Martian crust is 42-56 km on average, and thus thicker than the crusts of the Earth and Moon. Considered with the context of thermal evolution models, a thick Martian crust suggests that the crust must contain 50%-70% of the total heat production to explain present-day local melt zones in the interior of Mars., Geophysical Research Letters, 50 (12), ISSN:0094-8276, ISSN:1944-8007

Abstract

When NASA’s InSight lander touched down in Elysium Planitia, Mars, in November 2018 and deployed its seismometer SEIS, it ushered in a new age for planetary seismology - more than 40 years after the first attempt to record marsquakes with the Viking missions. SEIS, an extremely sensitive instrument, has by now provided near continuous seismic records for more than 3 years. Its rich dataset shows Mars to be seismically active, with over 1,300 marsquakes detected so far, mostly with magnitudes below 4. Despite their small size, these quakes provide important and unprecedented constraints on the interior structure of the planet, from the shallow subsurface via the crust, the lithosphere, and the mantle transition zone down to the core, and allow to study Martian tectonics and thermo-chemical evolution. Single-station seismology has answered some of the big questions about the interior of our planetary neighbour, and this contribution gives an overview of results and surprises so far.
