Revision of the New World species of the genus Leptogenys Roger (Insecta: Hymenoptera: Formicidae: Ponerinae)
Authors: Lattke John
Published: July 2023

The New World species of the genus Leptogenys are revised based upon their external morphology. The genus is present from southern U.S.A. to northern Argentina, including the Caribbean and Galapagos Islands. Eighty-one species are recognized, 13 are synonymized, and 49 are described as new. The New World fauna can be divided into 12 informal species groups and 8 species considered incertae sedis. A phylogeny using morphology recovers L. linearis as sister to the rest of the New World taxa, besides existence of a basal polytomy and two large clades. Reproduction is mostly through ergatoid queens, with gamergate reproduction apparently only present in several taxa outside of the pusilla clade, while winged queens are present only in 3 species of the pusilla clade. The African tramp species L. maxillosa is also present. Most species dwell in humid forested areas, but there are several arid zone endemics. Most species are specialist predators of oniscomorph isopods. There is no evidence for army ant behavior in the New World species. The generic diagnosis and a key for the identification of the workers is included, as well as illustrations of all the known New World species.
The adult head morphology of Dascillus (L.) (Dascilloidea: Dascillidae) and Glaresis Erichson (Scarabaeoidea: Glaresidae) and its phylogenetic implications
Authors: Anton Eric , Beutel Rolf
Published: July 2023

External and internal structures of the adult head of Glaresis sp. and Dascillus cervinus are described in detail and compared with conditions found in other polyphagan representatives such as Rhipicera sp. and members of Staphyliniformia and Elateroidea. The structures examined do not support a clade Scarabaeoidea + Dascilloidea. No potential synapomorphic features of the head could be identifi ed. In Dascillus a very unusual confi guration of mouthparts is described for the fi rst time, notably the inframandibular antepipharynx. This complex apomorphic feature was also found in members of different groups of Elateroidea s.l., but not in other potentially related lineages. This suggests a possible monophylum ‘Elateroidea s.l. incl. Dascilloidea’. Additional new arguments for such clade are: characteristic scale-like setae on the galea and ligula; a ventrally expanded and bipartite foramen occipitale; a sclerotized tub-shaped prepharyngeal suspensorium; an epipharyngeal surface uniformly covered with microtrichia; similarly shaped mandibles with a concave ventral surface. Characteristics of Dascillus are the presence of a M. verticopharyngalis (plesiomorphic), the presence of two muscles of the posterior hypopharyngeal suspensorium, and bifurcate galeomeres II and ligular lobes. New arguments for a clade ‘Staphyliniformia incl. Scarabaeoidea’ are presented. The most important are the following: presence of a ‘craniobasimaxillary’ muscle; articulation of antennal club segments strongly excentric on outer margin of segments; distal club segment with characteristic sensory pouch; scapus with long bristle- or peg-like setae; ligula separated into a pair of oval shaped and anteriorly setiferous sclerites. Possible autapomorphies of Scarabaeoidea are the following: anterior part of clypeus projecting and covering the labrum; anterior clypeal margin concave and with a transverse row of trichia on its frontal or ventral surface; gula large, rectangular and strongly bulged; inner mandibular edge deeply interrupted by semimembranous lobe. Additionally, a revised terminology of head musculature is newly introduced for Coleoptera.
A new Epiophlebia (Odonata: Epiophlebioidea) from China with a review of epiophlebian taxonomy, life history, and biogeography
Authors: Carle Frank
Published: July 2023

Epiophlebia diana sp.n. is described from larval specimens collected in the mountains of western Sichuan Province, China. Epiophlebian taxonomy, life history, and biogeography are reviewed, and keys provided for determination of the knownadults and larvae of Epiophlebia Calvert, 1903. Classification of Epiophlebia is revised as follows: Epiophlebia s.str. with E. superstes (Selys, 1889) type species and E. sinensis Li & Nel, 2012; and Rheoepiophlebia subgen.n. with E. laidlawiTillyard, 1921 type species and E. diana sp.n.. Behavioral, ecological and paleontological information is also evaluated and members of Epiophlebia acknowledged to have inhabited small high elevation streams of the east Palaearctic for possibly180 million years. Likely reasons are proposed for the enduring survival of Epiophlebia, its lack of a fossil record and the extinction of related groups.
New evidence on the mechanics of wing unfolding in Dermaptera (Insecta)
Authors: Haas Fabian , Hwen Justin Tan Chek , Tang Hung
Published: July 2023

The wing unfolding in Dermaptera is re-analysed for two species, Auchenomus sp. (Spongiphoridae) and Timomenus lugens (Bormans, 1894) (Forficulidae), based on several digital movie sequences made in the earwigs’ natural environment. The frames were separated and numbered sequentially to establish the time line of unfolding and (where available) folding. It is shown that the steps described earlier in contributions of the first author are confirmed, with the exception of the drivers. It has been assumed that the cerci are essential to unfold the wings. The current contribution clearly shows that this is not the case in all species: the wings can be unfolded without involvement of any other body part. In all examined sequences the wing packages are unfolded without any involvement of the cerci. Thus the Dermaptera are heterogeneous in this respect and this new finding is discussed in a behavioural and phylogenetic context.
Another species of European Ectobiinae travelling north - the new genus Planuncus and its relatives (Insecta: Blattodea: Ectobiinae)
Authors: Bohn Horst , Beccaloni George , Pfeifer Manfred
Published: July 2023

A new genus of Ectobiinae is described, Planuncus with the three new subgenera, Planuncus, Margundatus and Margintorus, containing species formerly belonging to the genera Phyllodromica (second subg.) and Ectobius (other subg.). New combinations: Pl. (Pl.) tingitanus (Bolívar, 1914), Pl. (Pl.) finoti (Chopard, 1943), Pl. (Pl.) vinzi (Maurel, 2012); Pl. (Margundatus) baeticus (Bolívar, 1884), Pl. (Margundatus) agenjoi (Harz, 1971), Pl. (Margundatus) erythrurus (Bohn, 1992), Pl. (Margundatus) intermedius (Bohn, 1992), Pl. (Margundatus) krausei (Bohn, 1992), Pl. (Margundatus) maculosus (Bohn, 1992), Pl. (Margundatus) paludicolus (Bohn, 1992), Pl. (Margundatus) princisi (Fernandes, 1962), Pl. (Margundatus) striolatus (Bohn, 1992); Pl. (Margintorus) nicaeensis (Brisout de Barneville, 1852). A new Ectobius species from Morocco is described: E. hipposiderus. The new genus and its subgenera are compared with the Ectobiinae genus Capraiellus and the newly described E. hipposiderus. The morphological phylogenetic analysis suggests the following relationships: E. hipposiderus + (Capraiellus + (Margintorus + (Margundatus + Planuncus))). The appearence of a new cockroach species belonging to the subgenus Planuncus in Germany and Great Britain is reported; the hitherto known distribution of the subgenus encompasses Algeria, Morocco, southern Spain, and France. Species affiliation and provenance of the immigrant remain doubtful due to difficulties to separate the three known species. The possible reasons for the recent areal expansion of the species are discussed.
DNA barcoding of flat bugs (Hemiptera: Aradidae) with phylogenetic implications
Authors: Grebennikov Vasily , Heiss Ernst
Published: July 2023

This work introduces an open online library of Aradidae DNA barcodes, specimen images and geographical data with intent of promoting further community-based DNA barcoding of flat bugs. We report the results of an attempt to DNA barcode 191 dry specimens of the flat bugs representing all 8 extant subfamilies of the Aradidae. 145 sequences > 300 nt in length were obtained (76% success rate; all can be seen in a publicly accessible dataset “World Aradidae”, doi: dx.doi.org/10.5883/DS-WAHG), 98 of them representing 55 species and 29 genera were > 500 nt (51%). These 98 sequences were combined with 10 Heteroptera-Trichophora outgroup taxa into an aligned matrix of 658 positions and variously analysed to obtain the first DNA-based phylogeny for the Aradidae, which was our second goal. Aradidae and five of its subfamilies (Aradinae, Aneurinae, Mezirinae, Isoderminae, Calisiinae) were recovered as monophyletic, although the latter two were markedly underrepresented. The subfamily Carventinae was consistently polyphyletic. Isoderminae + Prosympiestinae was recovered as a clade, while Aradinae formed the sister group to the rest of the family in three of four analyses. The genus Mezira appeared polyphyletic while the genus Neuroctenus was paraphyletic with respect to Ctenoneurus.
The higher phylogeny of Leptophlebiidae (Insecta: Ephemeroptera), with description of a new species of Calliarcys Eaton, 1881
Authors: Godunko Roman J. , Sroka Pavel , Soldán Tomáš , Bojková Jindřiška
Published: July 2023

A detailed morphological description of the adults and larvae of Calliarcys van sp.n., the second representative of the genus Calliarcys Eaton, 1881 is provided, including a differential diagnosis with regard to Calliarcys humilis Eaton, 1881. C. van sp.n. is distinguished in the adult mainly by the colouration of the upper part of male compound eyes, shape of costal process of hind wings, and genitalia; in larvae it is distinguished by the shape of hypopharynx and labium; and by comparatively densely arranged unbranched longitudinal ridges on the exochorion of the fusiform eggs. The generic diagnosis for Calliarcys is re-evaluated and specified. The genus had already previously been proposed to constitute the subfamily Calliarcyinae within Leptophlebiidae, a concept which has not been generally accepted. Now this classification is tested by phylogenetic analysis, for the first time using a set of 20 morphological characters. Ambiguous characters from previous studies are discussed. Leptophlebiinae is confirmed as sister group to all remaining Leptophlebiidae. Calliarcys is revealed as sistergroup of Habrophlebiinae + Atalophlebiinae s.l., thus justifying its classification as a subfamily Calliarcyinae.
Tackling generic limits for the Neotropical Philonthina with a phylogenetic approach: revision of the genera Linoderus Sharp and Odontolinus Sharp (Coleoptera: Staphylinidae)
Authors: Chani Posse Mariana
Published: July 2023

A systematic revision and a phylogenetic analysis of the closely related Neotropical genera Pescolinus Sharp, 1885 and Neopescolinus gen.n. (Staphylininae: Staphylinini: Philonthina) are presented. Both genera are revised using characters of external morphology and male and female genitalia, with keys for identification, diagnoses, descriptions, illustrations, a phylogenetic analysis, and a distributional map. Eight valid species are recognized for Pescolinus: P. palmatus Sharp, P. schmidti Bierig and six new species, P. aeneus, P. cartagensis, P. costaricensis, P. montanus, P. moyae and P. varablanquesis. Neopescolinus gen.n., from Costa Rica, is described for one new species, N. nevermanni. Lectotype is designated for Pescolinus palmatus Sharp. The cladistic analysis shows Pescolinus as a monophyletic genus which forms together with Linoderus Sharp, Odontolinus Sharp and Neopescolinus a well supported clade that belongs to a natural group of Neotropical Philonthina.
Non-monophyly of the "cydnoid" complex within Pentatomoidea (Hemiptera: Heteroptera) revealed by Bayesian phylogenetic analysis of nuclear rDNA sequences
Authors: Lis Jerzy , Ziaja Dariusz , Lis Barbara , Gradowska Paulina
Published: July 2023

The “cydnoid” complex of pentatomoid families, including Cydnidae, Parastrachiidae, Thaumastellidae, and Thyreocoridae, is morphologically defined by the presence of an array of more or less flattened stout setae (called coxal combs), situated on the distal margin of coxae. These structures, suggested to prevent the coxal-trochanteral articulation from injuries caused by particles of soil, sand or dust, by their nature and function are unknown elsewhere in the Heteroptera. As such, coxal combs were regarded as a synapomorphy of this group of families, and enabled the definition of it as a monophylum. In this study, the monophyly of the “cydnoid” complex of families is tested for the first time, based on the combined analysis of nuclear ribosomal DNA sequences (28S rDNA D3 region, and 18S rDNA). Combined analyses of both genes are performed using Bayesian methods with the covarion option in MrBayes 3.2.0. Non-monophyly of the entire “cydnoid” complex of families, and independent origins of their coxal combs is suggested. The family Thaumastellidae is demonstrated not to be part of this complex as previously proposed. Challenging the existing classification system, the use of the name “cydnoid” complex is indicated as unwarranted, and therefore it should no longer be applied to this group of families.
Eyes in the dark ... Shedding light on the antlion phylogeny and the enigmatic genus Pseudimares Kimmins (Neuropterida: Neuroptera: Myrmeleontidae)
Authors: Badano Davide , Aspöck Horst , Aspöck Ulrike , Haring Elisabeth
Published: July 2023

The systematic position of the antlion Pseudimares Kimmins has been disputed since description of the genus. Pseudimares is one of the most enigmatic and unusual members of Myrmeleontidae and probably of all Neuroptera. The taxon has been usually tied to the antlion subfamily Palparinae, although its phylogenetic affinities have never been thoroughly investigated and the monophyly of the subfamily as a whole has never been corroborated. We reconstruct for the first time the phylogenetic affinities of Pseudimares based on both morphological and molecular genetic data. The widely accepted subfamily level subdivision of antlions (Stilbopteryginae, Palparinae, Myrmeleontinae) is refuted in all our analyses, since Stilbopteryginae in the traditional sense are recovered as deeply nested within Myrmeleontidae forming a monophylum with Palparinae, while Myrmeleontinae are poorly supported by the parsimony analysis. In our morphology-based parsimony analysis, Pseudimares is the sister taxon of Stilbopteryx and Aeropteryx, which makes the traditional Palparinae paraphyletic. This result is further supported by our phylogenetic reconstruction based on molecular data, which found a clade including Pseudimares and Stilbopteryx, which is nested within the traditional Palparinae. The high genetic distances measured among the analysed taxa suggest that these groups quickly diverged in ancient times, although they remained morphologically homogeneous. In conformity with the results of the phylogenetic analyses, we propose a new classification scheme for antlions, one that merges Stilbopteryx and Aeropteryx into an expanded concept of the subfamily Palparinae.
The systematic position of the stonefly †culonga Sinitshenkova, 2011 (Plecoptera: Leuctrida) reassessed using Reflectance Transforming Imaging and cladistic analysis
Authors: Cui Yingying , Toussaint Séverine , Béthoux Olivier
Published: July 2023

The phylogenetic position of the insect species †culonga Sinitshenkova, 2011, recovered from the Khasurty locality (Transbaikalia, Russia; Early Cretaceous), is re-investigated. This fossil needle stonefly has been considered an Exeleuctrida nec Mioleuctrida & Eleuctrida based on the organization of the hind wing venation opposite the arculus. We reconsidered this interpretation based on a direct observation, complemented by a Reflectance Transforming Imaging file. Our investigation indicates that the species displays the defining character state of Eleuctrida while it lacks the defining character state of Mioleuctrida. Due to inconsistencies in the character state combination displayed by the species, we carried out a cladistics analysis. The species †culonga is recovered as an Eleuctrida nec Mioleuctrida, and therefore represents a suitable calibration point for a node more recent than previously assumed, and incidentally demonstrates that Mioleuctrida belongs to Eleuctrida.
High diversity of Cetiocyon beetles (Coleoptera: Hydrophilidae) along an elevational gradient on Mt. Wilhelm, New Guinea, with new records from the Bird's Head Peninsula
Authors: Szczepański Wojciech , Vondráček Dominik , Seidel Matthias , Wardhaugh Carl , Fikácek Martin
Published: July 2023

A major component of the “Our Planet Reviewed – Papua New Guinea” project was to evaluate insect diversity along an elevational gradient on Mt. Wilhelm (Madang Province, Papua New Guinea), the fourth highest peak in New Guinea. Flight intercept traps were installed at eight sites separated by approximately 500 m in elevation from 200 m a.s.l. to 3700 m a.s.l. Here we focus on the water scavenger beetle genus Cetiocyon (Coleoptera: Hydrophilidae) collected as part of this project. Cetiocyon species are uniform in much of their external morphology, but diagnostic characters are found in the male genitalia. Our aim was to test the hypothesis that local species diversity was high, and that Cetiocyon species diversity is elevationally structured. A small amount of additional material from western New Guinea (Bird’s Head Peninsula: Arfak Mts.) was also examined. Ten new species are described, seven from Mt. Wilhelm Cetiocyon paweli sp.n., C. depilis sp.n., C. onyx sp.n., C. augai sp.n., C. ibiscanus sp.n., C. mogianus sp.n., and C. gemellus sp.n., and three from the Arfak Mountains: C. jakli sp.n., C. colossus sp.n., and C. hamifer sp.n.. Twelve Cetiocyon species were found on the slopes of Mt. Wilhelm, most of which were only found at one or two neighboring elevations. The largest diversity of species was found at intermediate elevations (1200 – 1700 m). We successfully sequenced the 3’ end of mitochondrial cox1 gene for 10 species, which we used along with morphological characteristics to infer a species level phylogeny and examine the effect of elevation on species diversity. Interspecific genetic distances were significantly lower at higher elevations on Mt. Wilhelm, and our phylogenetic reconstruction suggests that Cetiocyon ancestrally inhabited low or intermediate elevations. As the result of recent research eighteen Cetiocyon species are currently known form New Guinea. An updated identification key to all New Guinean species is included, along with photographs and illustrations of relevant morphological characters.
Molecular evidence for the subfamilial status of Tetralobinae (Coleoptera: Elateridae), with comments on parallel evolution of some phenotypic characters
Authors: Kundrata Robin , Gunter Nicole , Janosikova Dominika , Bocak Ladislav
Published: July 2023

Tetralobinae is a distinct click-beetle lineage containing 78 species in seven genera. Adults are large-bodied, and larvae live in termite nests and are grub-like unlike typical elaterid wireworms. Their taxonomic position in the Elateridae has been unstable and they were treated either as a separate elaterid subfamily or a tribe within Agrypninae. Here, we provide the first molecular investigation of Tetralobinae to test their phylogenetic position using two nuclear and two mitochondrial molecular markers from three total taxa, one from each of the following genera: Tetralobus Lepeletier & Audinet-Serville, Sinelater Laurent, and Pseudotetralobus Schwarz. Two different datasets were analyzed, Elateridae (181 terminals) and Elateroidea (451 terminals), both composed by the earlier published datasets supplemented with the newly produced tetralobine sequences. The results suggest that Tetralobinae is the sister lineage to the remaining Elateridae and that warrants the subfamilial status instead of an subordinate position in the Agrypninae. Pseudotetralobus (Australia) was sister to the Tetralobus (Africa) + Sinelater (China) consistent with previously published morphological analysis. Additionally, we discuss the homoplastic phenotypic characters which were used for building the earlier click-beetle classification, and which indicated the relationships between Tetralobinae and Agrypninae.
The head morphology of Micromalthus debilis (Coleoptera: Micromalthidae) - an archostematan beetle with an unusual morphology and a unique life cycle
Authors: Yavorskaya Margarita , Hörnschemeyer Thomas , Beutel Rolf
Published: July 2023

Cephalic features of Micromalthus debilis were examined and described in detail for the first time. The head displays several seemingly plesiomorphic features compared to other extant species of Archostemata, especially representatives of Cupedidae and Ommatidae. Cephalic protuberances characteristic for species of these two families are missing and antennal grooves are also absent. The surface of the head capsule is largely smooth, without the characteristic tubercles found in stemgroup beetles and ommatid and cupedid species. Cuticular scales, probably ancestral for Archostemata and possibly for Coleoptera, are also completely absent. The arrangement of three mandibular teeth in a vertical row and an immobilized labrum are derived features shared with Ommatidae. The maxillary endite lobes are absent, as in the very small Crowsoniella relicta (Crowsoniellidae). Like in all other examined archostematan species, mandibular molae and prosthecae are missing. The simplified maxillae apparently play no role in the food uptake but rather function as accessory “ventral antennae”. Derived features include the partly reduced maxillary musculature and lack of extrinsic labial muscles. Apomorphies of the digestive tract include the sclerotized median protuberances of the anterior epipharynx and hypopharynx, and the presence of a vertical anterior pharyngeal loop and a subcerebral postpharyngeal pouch. The tentorium is strongly reduced. Consequently, all antennal muscles originate from the head capsule. A very unusual and possibly plesiomorphic feature is the presence of a short salivary tube and two associated muscles. This is a unique condition in Coleoptera as far as known at present. Structural features suggest that Micromalthus probably feeds on wood infested with fungi. A robust phylogenetic evaluation of anatomical features is presently not possible due to the lack of data for Crowsoniella (Crowsoniellidae) and Sikhotealinia zhiltzovae (Jurodidae). Moreover, phylogenetic and evolutionary interpretations are impeded by possible effects of vestigialization of adults possibly resulting from endosymbionts (e.g. Wolbachia, Rickettsiales).

We present a review of Orchidaceae Juss. of the northern part of Kazakhstan, within the steppe, forest-steppe and semi-desert habitats of the country (Pavlodar, northern Kazakhstan, Kostanay, Akmola, Aktobe, West Kazakhstan, partially Karaganda and East Kazakhstan regions). The investigation is based on herbarium materials, literature data and field observations. We examined material from the following herbarium collections: LE, MW, TK, MHA, SVER, KUZ, ALTB, AA, NUR, KG, KSPI, NS, NSK, MOSP, ORIS, PPIU, totalling 288 herbarium specimens. The paper presents data in the form of revision, focusing on orchids of the northern part of Kazakhstan. It is accompanied by maps indicating localities, notes on habitat preferences, phenology and conservation status. A total of 25 species of 16 genera were recorded, of which eight are included in the Red Book of Kazakhstan (2014). According to our data, we propose to enlarge the number of protected orchids by adding the following nine species: Corallorhiza trifida, Epipactis atrorubens, Gymnadenia conopsea, Hammarbya paludosa, Herminium monorchis, Liparis loeselii, Malaxis monophyllos, Neottia camtschatea and Spiranthes australis. The most widespread species in the studied region are Dactylorhiza incarnata, D. umbrosa and Epipactis palustris. The rarest species (single locality only) are Epipactis atrorubens, E. helleborine, Epipogium aphyllum, Hammarbya paludosa and Herminium monorchis.
Robust Inference on Infinite and Growing Dimensional Time‐Series Regression
Authors: Gupta Abhimanyu , Seo Myung Hwan
Published: July 2023

We develop a class of tests for time‐series models such as multiple regression with growing dimension, infinite‐order autoregression, and nonparametric sieve regression. Examples include the Chow test and general linear restriction tests of growing rank
p. Employing such increasing
p asymptotics, we introduce a new scale correction to conventional test statistics, which accounts for a high‐order long‐run variance (HLV), which emerges as
p grows with sample size. We also propose a bias correction via a null‐imposed bootstrap to alleviate finite‐sample bias without sacrificing power unduly. A simulation study shows the importance of robustifying testing procedures against the HLV even when
p is moderate. The tests are illustrated with an application to the oil regressions in Hamilton (2003).
Relações entre natureza e sociedade em Poesias, de Dante Milano
Authors: Kukul Vanessa Moro
Published: July 2023

Neste artigo, propõe-se uma reflexão a respeito das relações entre natureza e sociedade a partir da leitura de poemas selecionados de Poesias, de Dante Milano (1979), especialmente da peça ‘Jardim público’. Assumindo como referência a crítica à racionalidade moderna formulada por Adorno e Horkheimer (1985), segundo a qual a razão esclarecida procurou desencantar o mundo, dominando e subjugando o supostamente ameaçador mundo natural, procura-se meditar de que maneira em uma obra produzida por um poeta moderno/modernista brasileiro (de uma modernidade incompleta e periférica) essa crítica é particularizada. Para tanto, além dos autores da Teoria Crítica, fundamentam o estudo autores como Ulpiano Meneses, Octavio Paz, Jeanne Marie Gagnebin, Paul Ricoeur, entre outros. A leitura dos poemas, conforme a perspectiva assumida, indica que uma das forças da obra milaniana é a problematização da relação entre homem e natureza. Percebeu-se que as tensões resultantes da cisão entre homem e natureza não escamoteiam as consequências trágicas desse processo e frequentemente apontam para a assunção de uma voz crítica que irrompe no animismo da natureza e na denúncia da reificação do homem. Neste estudo, estruturado em três partes intituladas ‘Das imagens e das paisagens’, ‘O jardim como paisagem cultural’ e ‘Um ‘jardim’ de memórias’, aponta-se, ainda, a conservação de elementos do mundo empírico na fatura dos poemas.
Negative and positive ageism in an Italian sample: how ageist beliefs relate to epistemic trust, psychological distress, and well-being
Authors: Fiorini Bincoletto Alice , Zanini Ludovica , Spitoni Grazia Fernanda , Lingiardi Vittorio
Published: July 2023

Ageism is a social issue of growing concern; ageist beliefs can shape the individual and collective experience of aging. The present study aimed to explore positive and negative ageism in young adults (YA) (18-30 years) and adults (AD) (31-60 years) and their relationship with epistemic trust, psychological distress, and psychological well-being. 301 Italian adult participants completed an online survey that included the following self-report questionnaires: attitudes towards older people scale, epistemic trust, mistrust and credulity questionnaire, depression anxiety stress scale-21, and Warwick-Edinburgh mental wellbeing scale. Negative ageism was significantly higher in YA compared to AD; on the contrary, AD presented more positive ageism than YA. When considering the entire sample, negative ageism was correlated with various dimensions of psychological distress and epistemic trust. A mediation model revealed that epistemic mistrust fully mediated the relationship between age and negative ageism, suggesting that changes in ageist beliefs that seem to occur with age are mediated by a mistrustful epistemic stance. Future research should focus on further exploring the link between epistemic trust, mental health, and holding ageist beliefs. The results are also discussed in terms of their implications for the treatment of older patients.

17-α methyl testosterone is a major endocrine disrupting chemical (EDCs), reported harmful effect on endocrine system of aquatic animals. To study the impact of 17-αMT on olive barb (Puntius sarana) gonad, sixty fishes were collected for in vitro experiment. Hormonal treatments were carried out 90 days with three distinct hormonal dosages (T1:40 mg/kg; T2:60 mg/kg and T3:90 mg/kg) mixed with pelleted feed and no hormone in control tank (C). Each 30 days intervals, histological analysis was performed to observe alterations in the gonad due to the effect of 17α-MT. Four gamete developmental stages of female P. sarana ovary were identified through microscopic examination named immature, previtellogenic, vitellogenic and mature stage. Mild to moderate histological abnormalities has been observed in ovary for different treatments. T1 showed apparently normal histology except some alterations like empty follicle (ef), lipid droplet (ld), vitelline envelop breakdown (veb), but pronounced alterations were detected at higher concentration T2 and T3, increasing with longer exposures for instance degenerated nucleus (dn), atretic follicle (af), thickened vitelline envelop (tve), residual oocyte (roc). This preliminary study revealed more profound responses to EDCs exposure in the olive barbs which could serve as a model bio-indicator in ecotoxicological study.

Industry 4.0, as defined by the disruptive innovation phenomenon, focuses on digital economic patterns, artificial intelligence, big data, and robotics. The Indonesian Ministry of Industry pushed aggressively for the development of “Industry 4.0.” PT Kereta Api Indonesia (Persero) is a technologically literate company, which indicates that their workplace is shaped and influenced by digital tools and technologies. PT KAI has three big technology-based projects in the works. The 105MT Sumbagsel, LRT Jabodebek, and Kereta Cepat Jakarta-Bandung are the three strategic plans. Presidential Regulation (Perpres) No. 98 of 2015 on the Acceleration of Integrated Light Rail Transit in the Jakarta, Bogor, Depok, and Bekasi Areas, which controls the development of transportation services to assist national growth, sparked the LRT Jabodebek project. Under Presidential Decree 93 of 2021, the government designated PT Kereta Api Indonesia (Persero) as the leader of the SOEs consortium for the KCJB project. PT Kereta Api Indonesia (Persero) has established digital cultures and executed human capital digital readiness in their organizations to assist their employees in doing work, acquiring information, and communicating. While employees must perform effectively with all of these new technologies, the implementation of digital culture in PT KAI is generally excellent but not perfect. Some staff are still unfamiliar with digitization and are finding it tough to adapt. To address the challenges of the 4.0 Industry, the relationship between digital culture, human capital digital readiness and employee performance in PT KAI should be examined. It’s also because an ideal digital culture and human capital digital readiness can improve employee performance. This study employed quantitative methods and data processing by SPSS 27. According to the data, there is a favourable and statistically significant association between digital culture, human capital digital readiness, and employee performance.

Financial distress is a condition where a company experiences financial difficulties that can go bankruptcy. Financial distress is an early warning system used to identify and improve the condition of a company before it reaches a crisis or bankruptcy. By predicting and understanding financial distress conditions from the beginning, it is expected to help management take preventive actions that can keep the company away from bankruptcy. This study aims to examine how liquidity and leverage affect financial distress mediated by profitability. This research specifically focuses on property and real estate companies listed on the Indonesia Stock Exchange for the period 2019 to 2021. This research applies a quantitative approach with a total population of 47 companies. The sampling technique used is saturated sampling. The data is analyzed using path analysis. The result shows that liquidity has an influence on profitability, but leverage does not affect profitability.

Authors: Lin Tay Zar , Oo San San
Published: July 2023

Myanmar's mental health and well-being have been profoundly impacted by the COVID-19 pandemic and political unrest. The prevalence of reported depressive symptoms and suicidal ideation highlights the imperative need to evaluate mental health access and services throughout the nation. Population anxiety and distress have increased as a result of the pandemic containment measures and political unrest. Access to mental health services is hindered, particularly in rural and minority-populated areas, by outmoded mental health legislation and a lack of trained professionals, as well as by language barriers. For the development of focused interventions and support systems, it is essential to understand the present situation of mental health access. For the promotion of mental health services, government, INGOs, and local communities are required to collaborate. Myanmar can foster resilience and well-being by prioritising mental health and employing comprehensive strategies, resulting in a healthier and more inclusive society for the citizens.
