Authors: Wasu Suksuwan  , Makatar Wae-hayee
Published: January 2025

A study was conducted on a combustion chamber, with a primary focus on evaluating the influence of different air inlet configurations, specifically the single tangential inlet (ST) and double tangential inlet (DT), on combustion performance and flue gas. The feedstock was palm kernel cake, with a steady flow rate of 3 kg/hr, while the airflow is regulated to maintain an excess air ratio (EAR) of 2. The investigation encompasses temperature profiles, streamline analyses, and flue gas composition, all of which were crucial factors in assessing the combustion efficiency (C.E.) of these configurations. The results revealed distinct advantages associated with the DT configuration. It consistently demonstrated higher temperatures, symmetrical flow patterns, and improved combustion efficiency when compared to the ST setup. These findings underscore the DT configuration as a more efficient and environmentally friendly choice for combustion processes.

Published: January 2025

The strategic role of human resources can give an organisation strength in realising its business goals. One of the organisational strengths of human resource management is employee engagement. Gallup Organisation likens employee engagement as a positive emotional bond that employees have and the commitment that employees have (Gallup, 2013). The company must have a good strategy so that employees have a good commitment to the company and the intention to leave will be reduced. Employer Branding is a strategy or company to create a pleasant work environment, positive and competitive behaviour, good teamwork, a good reward system, good organisational governance, and a culture of learning and adequate training, with this, employees will be proud to work because the company is cared for, therefore employees will improve performance for the better and be comfortable at work so as to reduce the intensity of employees to leave the company voluntarily. XYZ University with new management and ownership changes has a management strategy that can realise employee attachment to the organisation. The organisation will get a lot of human resource strength in line with the strategy run by the organisation. This research uses qualitative methods with data collection techniques through interviews, observations, documentation studies. Data validity and data credibility were tested using triangulation techniques. The subjects of this study were five employees from the leadership level and non-academic staff. The result of this research is XYZ University implements employer branding by providing motivation to increase employee engagement.

Published: January 2025

Abstract: Subsidizing fuel oil (BBM), mainly diesel fuel, has become a strategic policy of the Indonesian government to support the transportation sector, including ferries. Subsidies are designed to maintain price stability and support efficient operations. The increase in the realization of fuel subsidies every year shows challenges in its management and allocation. This study aims to analyze the effectiveness and efficiency of the allocation of subsidized diesel quotas on PT ASDP Indonesia Ferry (Persero) crossing vessels in the Merak-Bakauheni crossing, as well as accountability for use. This research uses a qualitative method with a descriptive approach, involving 11 key informants with direct experience in monitoring the use of subsidized diesel. Data were collected through in-depth interviews, observation, and analysis of relevant documents. The results showed that the preparation of the subsidized diesel quota allocation has been running effectively, and the provisions set by BPH Migas carry out the distribution of subsidies. Some aspects require improvement, especially monitoring and accountability, to ensure the subsidy is used optimally. Although the allocation and distribution system of diesel fuel subsidies for PT ASDP Indonesia Ferry (Persero) crossing vessels has been quite effective, monitoring and reporting mechanisms are needed to ensure the subsidies are used optimally.

Published: January 2025

Ortodontic treatment is an important effort to improve dentocraniofacial structure in both children and adults. However, public perception regarding ortodontic treatment by general dentists and specialist ortodontists still needs to be better understood. This study aims to examine the perceptions of FIKOM and FISIP UPDM(B) students toward ortodontic treatment. This is an analytical study with a cross-sectional design conducted online. The research subjects were 501 students from FIKOM and FISIP UPDM(B). The study shows that the majority of FIKOM and FISIP UPDM(B) students tend to trust specialist dentists more for their ortodontic treatment. The research indicates that FIKOM and FISIP UPDM(B) students have greater trust in ortodontic treatment provided by specialists due to their perceived expertise. Although awareness of the importance of specialization has increased, some still receive ortodontic treatment from general dentists.

Published: January 2025

Thalassemia is a blood disorder which characterized with decreased or absence of globin chain in red blood cell thus disrupted hemoglobin synthesis. Hb E/ β-Thalassemia is a thalassemia syndrome of intermedia severity with a very heterogeneous clinical spectrum. The most presented sign and symptoms in Hb E/ β-Thalassemia are pallor and abdominal mass enlargement. One of the most accurate and fast methods to diagnose thalassemia is High Performance Liquid Chromatography. Hb E/ β-Thalassemia based on clinical severity, can start with blood transfusions, and when serum ferritin level increased, it can also begin with iron chelation therapy to prevent complication from iron overload in the body.  We have reported a case of a 28-year-old patient diagnosed with Hb E/ β-Thalassemia, with hemoglobin level is 5,1 g/dL and serum ferritin 1029 ng/mL, started to treat with blood transfusions and iron chelation therapy. Early detection on Hb E/ β-Thalassemia patient will give better outcome to prevent complications caused by the disease it self or treatment given.

Exploring the Effectiveness of Whatsapp Application on Teaching and Learning at One Midlands Teacher Education Institution in Zimbabwe
Authors: Konyana Shoorai , Modise Motalenyane Alfred
Published: January 2025

Generally, social media platforms have been utilised to convey personal and non-academic information. Lecturers at higher education institutions have treated social media as a non-formal means of communication. However, with the advent of COVID-19-induced lockdowns, social media platforms gained importance in conveying both formal and non-formal information. This study thus analysed the effects of utilising the whatsapp platform for teaching and learning at one Midlands Teacher Education institution. Through the connectivism lens, the study adopted a qualitative case study generating data through interviews, observations and focus group discussions. Findings pointed to the fact that though sceptical about social media platforms in general, lecturers and students utilise whatsapp to a greater extent for online teaching and learning and for conveying important information. Most students own smartphones and Whatsapp, and though prone to cyberbullying and circulation of falsehoods, the platform was preferred to other platforms as it was categorised under cheaper modes of conveying information to many people at once. The study recommends that while integrating social media applications in teaching and learning, lecturers and students should verify the authenticity of social media information. This study contributes to the ongoing discourse on the use of blended learning and the possibility of utilising social media in educational contexts.

Exploring the Experiences of Teachers in Integrating Technology into Teaching English in Rural Primary Schools in South Africa
Authors: Maja Margaret Malewaneng , Naidu Katharine , Tshabalala Samson Letsoaka , Malatji Makwalete
Published: January 2025

The integration of technology in schools, specifically in teaching English First Additional Language (EFAL), has become vital in the education sector as a means of preparing learners and teachers for 21st-century classrooms. As the literature shows, the integration of technology allows learners to engage deeply with content and promotes authentic learning. The TPACK theory was used in this study to examine how South African primary school teachers in rural areas of Limpopo integrated technology into the teaching of EFAL in schools. The study adopted an interpretive paradigm and followed a qualitative research approach. A case study research design was also used. Data was collected from five primary schools, following purposive sampling to select 11 participants. The researchers used semi-structured interviews to collect data from the participants. It was found that most teachers in Limpopo primary schools cannot use technology in the classroom. The study further revealed that the schools could not afford the cost of internet connectivity. Even though some participants demonstrated that they could use technology for teaching and learning, they could not integrate it for effective participation in the classroom. The study concluded that the use of technology for teaching EFAL promotes quality teaching and learning and could also improve authentic learning. It is therefore recommended that teachers and learners be trained on how to use technology as part of the teaching and learning process. Moreover, the study recommended that higher education institutions and other stakeholders strengthen technological support to schools, for the effective teaching of EFAL and other subjects. This study offers stakeholders of the education system with guidelines on how to use technology for teaching and learning.

Low-energy Injection and Nonthermal Particle Acceleration in Relativistic Magnetic Turbulence
Authors: Singh Divjyot , French Omar , Guo Fan , Li Xiaocan
Published: January 2025

Relativistic magnetic turbulence has been proposed as a process for producing nonthermal particles in high-energy astrophysics. The particle energization may be contributed by both magnetic reconnection and turbulent fluctuations, but their interplay is poorly understood. It has been suggested that during magnetic reconnection the parallel electric field dominates the particle acceleration up to the lower bound of the power-law particle spectrum, but recent studies show that electric fields perpendicular to the magnetic field can play an important, if not dominant role. In this study, we carry out two-dimensional fully kinetic particle-in-cell simulations of magnetically dominated decaying turbulence in a relativistic pair plasma. For a fixed magnetization parameter σ
0 = 20, we find that the injection energy ε
inj converges with increasing domain size to ε
inj ≃ 10 m

e

c
2. In contrast, the power-law index, the cut-off energy, and the power-law extent increase steadily with domain size. We trace a large number of particles and evaluate the contributions of the work done by the parallel (W
∥) and perpendicular (W
⊥) electric fields during both the injection phase and the postinjection phase. We find that during the injection phase, the W
⊥ contribution increases with domain size, suggesting that it may eventually dominate injection for a sufficiently large domain. In contrast, on average, both components contribute equally during the postinjection phase, insensitive to the domain size. For high energy (ε ≫ ε
inj) particles, W
⊥ dominates the subsequent energization. These findings may improve our understanding of nonthermal particles and their emissions in astrophysical plasmas.

Gamma-ray bursts (GRBs) are the most luminous transients in the Universe. The interaction of the relativistic jet with the circumburst medium produces an afterglow and generates multiwavelength emission. In this work, we present simultaneous multiband photometry of GRB 240825A with the Multi-channel Photometric Survey Telescope (Mephisto) and analyze its temporal and spectral properties. The measurement began 128 s after the GRB trigger and continued until the fourth day, when the afterglow essentially diminished and the measured brightness was close to that of the host galaxy. Based on the multiband light curves in the uvgriz bands, we find that the optical flux density satisfies F

The Radio Fundamental Catalog. I. Astrometry
Authors: Petrov L. Y. , Kovalev Y. Y.
Published: January 2025

We present an all-sky catalog of absolute positions and estimates of correlated flux density of 21,942 compact radio sources determined from processing interferometric visibility data of virtually all very long baseline interferometry (VLBI) observing sessions at 2–23 GHz from 72 programs suitable for absolute astrometry collected for 30 yr. We used a novel technique of generation of a data set of fused observables that allowed us to incorporate all available data in our analysis. The catalog is the most complete and most precise to date. It forms the foundation and reference for positional astronomy, space geodesy, space navigation, and population analysis of active galactic nuclei (AGNs), and provides calibrators for phase referencing for differential astrometry and VLBI astrophysical observations. Its accuracy was evaluated through a detailed accounting of systematic errors, rigorous decimation tests, comparison of different data sets, and comparison with other catalogs. The catalog preferentially samples AGNs with strong contemporary parsec-scale synchrotron emission. Its milliarcsecond-level positional accuracy allows association of these AGNs with detections in a wide range of the electromagnetic spectrum from low-frequency radio to γ rays and high-energy neutrinos. We describe the innovative data processing and calibration technique in full detail, report the in depth analysis of random and systematic positional errors, and provide a list of associations with large surveys at different wavelengths.
Identification of 4876 Bent-tail Radio Galaxies in the FIRST Survey Using Deep Learning Combined with Visual Inspection

Published: January 2025

Bent-tail radio galaxies (BTRGs) are characterized by bent radio lobes. This unique shape is mainly caused by the movement of the galaxy within a cluster, during which the radio jets are deflected by the intracluster medium. A combined method, which involves a deep learning-based radio source finder along with visual inspection, has been utilized to search for BTRGs from the Faint Images of the Radio Sky at Twenty cm survey images. Consequently, a catalog of 4876 BTRGs has been constructed, among which 3871 are newly discovered. Based on the classification scheme of the opening angle between the two jets of the galaxy, BTRGs are typically classified as either wide-angle-tail (WAT) sources or narrow-angle-tail (NAT) sources. Our catalog comprises 4424 WATs and 652 NATs. Among these, optical counterparts are identified for 4193 BTRGs. This catalog covers luminosities in the range of 1.91 × 1020 ≤ L
1.4 GHz ≤ 1.45 × 1028 W Hz−1 and redshifts from z = 0.0023 to z = 3.43. Various physical properties of these BTRGs and their statistics are presented. Particularly, by the nearest neighbor method, we found that 1825 BTRGs in this catalog belong to galaxy clusters reported in literature.
The new problem of Chinlestegophis and the origin of caecilians (Amphibia, Gymnophionomorpha) is highly sensitive to old problems of sampling and character construction
Authors: Marjanović David , Maddin Hillary C. , Olori Jennifer C. , Laurin Michel
Published: January 2025

The description of the small Late Triassic temnospondyl Chinlestegophis ushered in a potentially radically new understanding of the origins of the extant amphibian clades. Together with the fragmentary Rileymillerus, Chinlestegophis was argued to link extant caecilians to Permo-Triassic stereospondyl temnospondyls rather than to frogs and salamanders (and through them to amphibamiform temnospondyls or to brachystelechid and lysorophian “lepospondyls”). We critically review the comparative description of Chinlestegophis and phylogenetic analyses of previous studies. Most of the features previously interpreted to be shared by caecilians, Chinlestegophis and/or other stereospondyls have different distributions than scored in the analysis. We also find no evidence for an incipient tentacular sulcus in Chinlestegophis, and note that its vertebrae, unreduced ribs and dermal shoulder girdle are unlike those of any extant amphibians (nor their likely sister group, Albanerpetidae). Furthermore, the original matrices contain misscores accreted over more than a decade that likewise influence the results. Some features are coded as multiple redundant characters: the double toothrow of Chinlestegophis, other stereospondyls, and caecilians is represented as seven characters. Analysis of the unmodified matrix yields much less resolution than originally reported, and tree topology is altered by a small change to the taxon sample (the addition of Albanerpetidae), limited revisions of irreproducible scores, and ordering the most obviously clinal characters; any one of these changes removes Chinlestegophis from Lissamphibia, and confirms it as a stereospondyl.
The last eryopids: Clamorosaurus and Syndyodosuchus from the late Kungurian (Cisuralian, Permian) of Russia revisited
Authors: Werneburg Ralf , Witzmann Florian
Published: January 2025

The three Permian (Cisuralian) temnospondyls Syndyodosuchus tetricus, Clamorosaurus nocturnus and C. borealis from the Pechora Coal Basin in Russia, are redescribed. The assignment of Clamorosaurus to the Eryopidae is confirmed, and several new characters are presented in detail. Syndyodosuchus tetricus is identified as an eryopid for the first time, as this taxon was previously regarded as a basal stereospondylomorph. In our phylogenetic analysis, S. tetricus forms a polytomy at the base of the Eryopidae together with Actinodon frossardi and Osteophorus roemeri. More crownward, Glaukerpeton avinoffi and Onchiodon labyrinthicus build a polytomy, followed by O. thuringiensis and Stenokranio boldi as successive sister taxa of a monophyletic Clamorosaurus plus Eryops megacephalus. A reweighted analysis finds A. frossardi at the base of Stereospondylomorpha; the Eryopidae is completely resolved and consists of S. tetricus, O. roemeri, G. avinoffi, O. labyrinthicus, O. thuringiensis, S. boldi and E. megacephalus as successive outgroups to Clamorosaurus. The phylogenetic position of Clamorosaurus among the most derived eryopids is congruent with its young stratigraphic age, whereas for S. tetricus as a basal eryopid a long ghost lineage has to be assumed. Although being coeval, the two genera occurred in different environments, with Clamorosaurus being preserved in lacustrine limestones wheras S. tetricus was found in a coal bed. The lifestyle of these eryopids can best be designated as semi-aquatic.
A plastron fragment reveals a previously unrecorded turtle species in the Eocene of Messel Pit, Germany
Authors: Ascarrunz Eduardo , Joyce Walter G.
Published: January 2025

Depending on taxonomic opinion, between four and five turtle species are well attested for the Middle Eocene Messel Pit formation of Germany. Here, we describe specimen SMF ME-3495 from the Messel collection of the Senckenberg Museum in Frankfurt, which unambiguously corresponds to an additional turtle species. The specimen consists of a partial anterior plastral lobe that can be distinguished from other Messel turtle taxa on the basis of the presence of gular tubercles, an extensive epiplastral lip, narrow gulars that lap onto the entoplastron, and a sinuous gulo-humeral sulcus. The fragment is not sufficient to diagnose another contemporary European turtle taxon, but its epiplastral lip morphology is reminiscent of “ptychogasterid” geoemydids (Cryptodira). We also remark on bone corrosion consistent with “shell disease” and distinctive coloration.
The start of the scientific journal ‘Fossil Record’
Authors: Schultze Hans-Peter
Published: January 2025

This article describes the early years of the journal Fossil Record and the circumstances at the Museum für Naturkunde and the Humboldt University Berlin under which the foundation of the journal took place. The former Department of Palaeontology of the Museum für Naturkunde had a strong interest to publish its own scientific journal, and this led to the foundation of the journal in 1998 which is known today as Fossil Record. For reasons of a corporate similar appearance it was decided that the new journal as well as the two older scientific journals of the Museum für Naturkunde use the common title Mitteilungen aus dem Museum für Naturkunde in Berlin (Communications from the Museum of Natural History in Berlin) with subtitles for all three journals: Geowissenschaftliche Reihe for the palaeontological journal, Zoologische Reihe for the zoological journal and Deutsche Entomologische Zeitschrift for the entomological journal. With volume 9 (2006), the palaeontological journal appeared under the new title Fossil Record. From the beginning it was a goal of the editors to reach the international community by opening the journal to authors outside the museum and by publishing mainly in English. The palaeontological journal Fossil Record has developed from an in-house journal with international contributions to an internationally well cited journal.

Published: January 2025

Land snails and the Aegean Archipelago offer an intriguing combination for studying biodiversity, biogeography and ecology. A region with high environmental and temporal heterogeneity and a tri-continental biotic influence and a group of organisms with low active dispersal abilities, high endemism, as well as the particularity to leave shells as traces of past presence, set an ideal stage for testing biodiversity patterns and exploring multisource threats, especially in the era of the ongoing biodiversity crisis. In this study, we examine Helix godetiana, a large-sized, threatened and endemic land snail of the central and south Aegean Islands. The species has been extirpated from 22 of the 32 islands where it was historically present. We identify potential drivers of its extinction, as Helix godetiana faces several threats across its current range, including competitive exclusion by Cornu aspersum, a species with continuing expansion in the Aegean and climate change disrupting its unusual breeding cycle, which occurs in late spring. Our findings shed light on potentially major, yet previously unexplored, threats on endemic molluscs of the Aegean Islands, a European biodiversity hotspot.

Published: January 2025

A new leaf litter toad, Leptobrachella yongshunensissp. nov., is described on the basis of morphological, acoustic, and molecular data in this study. The new species was distributed in Xiaoxi National Nature Reserve, Yongshun County, Xiangxi Tujia and Miao Autonomous Prefecture, Hunan Province, China. Phylogenetical analysis revealed that the new species is sister species of L. wulingensis (p-distance 0.019 in 16s rRNA gene, p-distance 0.073 in COI gene). The duration of advertisement call was 194.2 ± 6.7 ms, the mean dominant frequency of the first note was 3.885 ± 0.066 kHz, and the mean dominant frequency of the second note was 3.914 ± 0.052 kHz. The new species can be distinguished from its congers by the following morphological characters: snout-vent length (SVL) 27.2–28.9 in males, SVL 26.2–31.6 in females; black spots on flanks; toes webbing rudimentarily; narrow fringes on toes; creamy white ventral body with indistinct black speckling at margins; dorsal body with sparse large warts, dense little wart grains, and longitudinal ridges; head width greater than head length; tibiotarsal articulation reaching to anterior edge of the eye; brick-red color in the dorsal surface; upper parts of iris bright coppery in life. We still supplemented the molecular data of the COI gene of L. wulingensis for further research. The discovery of the new species not only enhances the species diversity of the Wuling Mountains, but also suggests the hidden species diversity in the area.

La vallée du Gier, entre Lyon et Saint-Étienne, se caractérise par la persistance d’un tissu dense de petites entreprises industrielles, dans la métallurgie-mécanique notamment. L’analyse des parcours socio-professionnels des dirigeant·es de cette industrie historiquement implantée dans le territoire démontre l’existence d’un milieu entrepreneurial « ancré », où la carrière patronale s’appuie le plus souvent sur des héritages familiaux, de solides formations techniques et des réseaux de coopération plus ou moins formalisés. Ces dirigeant·es font face à des défis assez nouveaux de recrutement et de renouvellement, nés des tensions d’une industrie mondialisée, qui remettent en cause les processus habituels de transmission ou de reprise de ces entreprises.

Microstrip patch antennas (MPAs) are popular in wireless communication systems due to their compact size and easy-to-design properties. However, the performance of such antennas sometimes becomes limited, especially when used in location-based services that require either sophisticated antenna arrays-based radio frequency front-end (RFFE) design or complex signal processing techniques. This paper introduces the concept of an electromagnetic (EM) lens-assisted MPA where a polylactic acid (PLA) substrate-based EM lens is combined with a conventional MPA. Because the EM lens has focused ability, the EM lens-assisted MPA provides improved overall antenna performance. In this paper, we design and simulate the EM lens-assisted MPA and analyze the performance at different frequencies, i.e., 4.2 GHz and 10 GHz, and dielectric substrates for the MPA, i.e., FR4, RO4350b, and RT Duroid 5880. The obtained results show that the EM lens-assisted MPA, particularly the RT Duroid substrate- based MPA integrated with the EM lens, outperforms the traditional MPA without the EM lens. Furthermore, the proposed lens antenna can steer the beam as a function of the MPA position with less complexity and improved performance. Thus, the proposed EM lens antenna in this paper has the potential to revolutionize the RFFE design to be used for location-enabled services, especially in fifth/sixth generation (5G/6G) technology.

Le motet du XIVe siècle
Authors: Roger Kévin
Published: January 2025

Cette publication est la version remaniée d’un mémoire de recherche en musicologie soutenu en 2017 à l’Université de Bourgogne. L’objectif est d’étudier les relations pratiques et théoriques qui unissent la composition du motet et les sciences relatives à la mesure du temps à la fin du Moyen Âge. En partant de la forme périodique des motets dits « isorythmiques » rencontrés en France au XIVe siècle, les différentes parties de cet écrit proposent d’explorer comment l’essor du savoir astronomique, l’horlogerie mécanique et la popularité de l’astrologie ont pu influencer les compositeurs en quête d’une œuvre en marge des genres proprement poétiques. Entre la pluritextualité, les superpositions de répétitions rythmiques et mélodiques ainsi que les contenus littéraires sophistiqués, le motet se révèle singulier dans le paysage occidental et possède diverses connexions avec des disciplines variées. Tandis que le premier et le deuxième chapitre analysent la circularité du motet et l’usage de l’isopériodicité, les chapitres 3 et 4 se concentrent sur la mesure du temps dans la culture médiévale et signalent plusieurs concepts communs entre la composition polyphonique et le savoir astronomique ou encore l’horlogerie. Le dernier chapitre étudie pour sa part plusieurs références aux astres rencontrées dans quelques motets de provenance française.
Espaces de solidarité sous contraintes : la promotion du bénévolat dans la gestion des bagageries pour les personnes sans domicile à Paris
Authors: Herse Louka
Published: January 2025

Partant des résultats d’une enquête ethnographique de deux années, l’article analyse la politique du bénévolat mise en œuvre par la Ville de Paris pour créer des bagageries pour les personnes sans domicile. Les bagageries solidaires sont de nouveaux lieux d’assistance qui permettent aux personnes sans domicile de conserver leurs effets personnels en sécurité. À Paris, ville qui accueille la majorité des bagageries françaises, la création et la gestion des bagageries solidaires reposent sur une politique municipale de mobilisation de bénévoles. La Ville de Paris encourage et encadre le travail gratuit d’habitant·es pour étoffer le réseau d’assistance aux personnes sans domicile. Toutefois, le partenariat entre la municipalité et des associations bénévoles pose une série de questions concernant la nature et la qualité du service municipal accompli, car il s’apparente à une forme de privatisation non-lucrative de l’action publique locale.
Spaces of solidarity under constraints: The promotion of volunteering in the management of luggage storage for homeless people in Paris
Authors: Herse Louka
Published: January 2025

Based on the results of a two-year ethnographic study, the article analyses the voluntary work policy implemented by the City of Paris to set up luggage repositories for homeless people. Solidarity luggage storage are new forms of assistance that enable homeless people to keep their personal belongings safe. In Paris, which hosts most France's storage spaces for personal belongings, the creation and management of these centres is based on a municipal policy of mobilising volunteers. The City of Paris encourages and supervises free work by residents. As a result, the assistance network for homeless people is better equipped. However, the partnership between the municipality and voluntary associations raises a series of questions about the nature and quality of the municipal service provided, as it is akin to a form of non-profit privatisation of local public action.

Published: January 2025

In the ever-changing world of financial markets, the intersection between financial distress and performance is important. Financial distress, an entity's inability to satisfy its financial obligations, can seriously affect a company or individual's market value and stability. Sri Lanka's financial sector has recently faced difficulties, with certain institutions failing due to insolvency or regulatory noncompliance. The research intends to give significant insights to stakeholders, regulators, and investors in the Sri Lankan finance industry by utilizing Altman's Z-score model. This study examines the relationship between financial distress and financial performance in 22 licensed finance institutions in Sri Lanka from 2013 to 2022. The study's independent variable is financial distress, measured by Altman’s Z’Score model, and the dependent variable is financial performance, measured by Return on Assets (ROA) & Return on Equity (ROE). Descriptive analysis, Correlation analysis and panel data regression were used to analyze the data in the study. The study supported that financial distress significantly impacts the ROA and ROE which are considered as financial performance measurements. The higher distress firms showed a lower performance during the period. The main indication given where companies should focus on the distress of the company can be analyzed through the Altmans Z score model. Licensed finance companies can have proactive measurements to enhance the liquidity reserves and optimize the capital structure of the firm. The findings are significantly important for the management of Licensed finance companies in Sri Lanka to manage their future strategies. The study's result indicates a significant impact of financial distress on the financial performance of listed licensed finance companies in Sri Lanka.
