Further new taxonomical and paleontological notes on Haliotis stomatiaeformis Reeve, 1846 (Gastropoda Haliotidae)
Authors: Reitano Agatino , Di Franco Davide , Scuderi Danilo
Published: July 2024

The finding of new both recent and fossil materials of the Mediterranean small abalone Haliotis stomatiaeformis Reeve, 1846 (Gastropoda Haliotiidae) allowed a more detailed study of this rare species. Analogies between the paleo-environment in which the fossil material is contextualized and the peculiar environment where nowadays it still lives are made on account of the faunal assemblage comparisons. Data on the morphology of the protoconch and the external soft parts chromatism and a new iconography complete the information set on this “neglected” species.
An annotated type catalogue of the land and freshwater mollusks from Tunisia and Libya in the Natural History Museum “Giacomo Doria” of Genova (Italy)
Authors: Sparacio Ignazio , Liberto Fabio , Abushaalam Najla , Tavano Maria , Poggi Roberto
Published: July 2024

In the present work are listed the type specimens of land and freshwater molluscs from Tunisia and Libya deposited in the Natural History Museum “Giacomo Doria” of Genova (Italy). The historical nucleus of the malacological collections of the Museum of Genova is made up of the material collected by the young Giacomo Doria. After the official creation of the Museum in 1867, the malacological collection increased considerably in number of species and importance also through the material collected in various scientific missions organized by the Museum around the world. After 1916, the director Raffaello Gestro reorganized all this material and began the cataloging and selection of the type species. Nineteen nominal species described by Arturo Issel, Laura Gambetta, Jole Bisacchi and Rolf Arthur Max Brandt have been traced in these malacological collections. The type series described (types and syntypes) but also the material coming from the description localities and collected by the author himself (sometimes referred to as “topotypes”) were examined. For each taxa, the collection data obtained from the labels, the current taxonomic classification, the photographic documentation, remarks and the malacological bibliography are provided.
Presence of Brachytrupes megacephalus (Lefebvre, 1827) (Orthoptera Gryllidae) in the Oriented Nature Reserves “Capo Rama” (Terrasini, Palermo, Sicily) and “Torre Salsa” (Siculiana, Agrigento, Sicily)
Authors: Genco Laura , Callea Giovanni , Muscarella Calogero , Salemi Alessandro , Massa Bruno
Published: July 2024

The authors present preliminary findings regarding the distribution and habitat selection of Brachytrupes megacephalus (Lefebvre, 1927) (Orthoptera Gryllidae) within the “Capo Rama” and “Torre Salsa” Nature Reserves (Sicily, Italy). This elusive species is closely associated with undamaged coastal ecosystems and appears to be in decline in Italy. It has been listed in the European Union’s Habitat Directive 92/43/EEC and the European Red List. Consequently, a monitoring plan was initiated in March 2021 and continued into 2022. The monitoring involved identifying signs of presence (burrows, sand cones, and song) using zig-zag transects in sample areas, with the aim of collecting both presence/absence data and density information. The presence of the species has been confirmed at various sites within the two study areas and on the beach in Balestrate (Palermo). The data obtained are crucial for planning effective conservation initiatives for both the species itself and the ecosystems inhabited by it.

A new particular finding of Lethocerus patruelis (Stål, 1854) (Hemiptera Heteroptera Belostomatidae) on the Calabria Ionian coast
Authors: Lamanna Francesco , Dima Caterina
Published: July 2024

The first observation of Lethocerus patruelis (Stål, 1854) (Hemiptera Heteroptera Belostomatidae) on the Ionian coast of Crotone, in eastern Calabria (Italy), is documented. During some local naturalistic research on the Strongoli Marina beach a live adult specimen of this large Belostomatidae was collected and identified. The diffusion in Calabria and in general in Italy of this species, typical of Balkans, has not yet been completely ascertained thus the finding, albeit sporadic, represents an important event for the knowledge and control of the species. Only two other records of Lethocerus patruelis in Calabria are reported in the literature. One to the north in the city of Villapiana in the province of Cosenza and the other to the south in the small hamlet of Prunella in the municipality of Melito di Porto Salvo in the province of Reggio Calabria. This may indicate an increase of the presence of Lethocerus patruelis on the Calabrian Ionian coast.

“Just holding that space”: Using Culturally Relevant Pedagogy to Create Counterspaces for Black College Students in AANAPISI/HSI Classrooms
Authors: Lacy Nicholas , Chen Yea-Wen , Smith Damariyé
Published: July 2024

Black college students continue to face the specter of anti-Blackness which creates additional barriers to success and flourishing in higher education. This study investigates how instructors in higher education can provide racial equity to Black students in AANAPISI/HSI classrooms through counterspaces. We use culturally relevant pedagogy to investigate the experiences of 21 Black college students at an AANAPISI/HSI to understand better how higher education instructors can utilize counterspaces, places where Black college students can challenge dominant discourses and create a collegial learning environment. We identified three counterspace themes: (1) Mitigate Eurocentric Pedagogy, (2) Employ Black and Critical Scholarship, and (3) Foster Black Excellence Zones. Implications provide educators with ways to enact meaningful support both academically and socially to Black-identifying students in college classrooms.

You Don’t Have to be Their Best Friend: Complicating the Instructor-Student Relationship through a Mixed-Method Typology
Authors: Vallade Jessalyn , Rudick C. Kyle
Published: July 2024

The purpose of this study was to explore the nuances of instructor-student relationships with a nationally representative sample of students. Participants were randomly assigned to describe relationships with their best, worst, and/or last instructor and rate their satisfaction with each relationship, and the level of closeness with the instructor. Coding of student descriptions revealed 13 themes, organized into six pairs of constructive/destructive relationship anchors and one neutral category (Professional Relationship). Importantly, professional relationships were not as close as constructive relationships but were equally satisfying, indicating the closeness in instructor-student relationships has diminishing returns. Results are discussed in the context of instructional communication research and pedagogy.
So sorry your grandma died. Get that paper in.”: Graduate Teaching Assistants' Experiences of Student Grief in the Communication Classroom
Authors: Cherry Jessica , Densmore Carly
Published: July 2024

Graduate teaching assistants (GTAs) are faced with managing how to respond to student disclosures of grief in the classroom but often lack grief training from their universities when these instances occur. Good and Mad grief, and Critical Grief Pedagogy (CGP) are the frameworks for which this study is positioned. Through interviews with GTAs in the United States, we explore their experiences when engaging with student grief disclosures and revealed three main themes: regulations and boundaries, transactional exchanges in institutions, and the classroom being a human space. We also discuss how GTAs use CGP to manage these interactions. We further suggest that GTA training should include CGP to help prepare future instructors for student grief and welcome grief into the classroom.
What is the Goal of Defining Family? Best Practices for Teaching Family Communication
Authors: Phillips Kaitlin
Published: July 2024

Family Communication is an inherently value-laden class. When students walk into the classroom, some of them come with a very negative view of family, whereas others walk in with an extremely narrow view of family. By prioritizing and facilitating the importance of multiple definitions of families, instructors can move through more complex topics over the course of the semester knowing that students have an understanding of why defining family is important—even if they are hesitant to change their definition. In this article I present eight best practices for teaching family communication. This set of practices provides a foundation for educators to broach a value-laden topic while building classroom rapport.
Post-Truth's Effect on the Brain and the Future Self: A Critical Communication Pedagogy Response
Authors: Kahl David
Published: July 2024

The university was created for the critical examination of ideas to seek truth. However, the proliferation of post-truth messages has made this goal more difficult to reach, creating an important communication pedagogy problem. Hegemonic forces create post-truth messages to mislead people and play to their existing beliefs in order to maintain and advance power. Post-truth messages are particularly effective because they cause cognitive overload and temporal discounting. Critical communication pedagogy (CCP) is a means by which instructors and students can evaluate post-truth messages. CCP allows for dialogue to reduce the cognitive issues that post-truth messages cause and allow for the critical evaluation of post-truth messages for their (lack of) veracity. Doing so can lead students to take action to resist post-truth messages and their effects.
Engaging Impasse: Nurturing a Culture of Dialogic Engagement on a University Campus
Authors: Hawk Patricia
Published: July 2024

Universities have historically fostered spaces where students, faculty, staff, and administration can fruitfully engage in discussion around contentious issues. Current political divisions have had a chilling effect on these discussions inside and outside the classroom. To nurture a campus culture of dialogic engagement, the communication studies department in collaboration with the DEI office began a campus dialogue project that invited faculty, staff, students, and administration to participate in monthly dialogues focused on cultural impasse topics. This 5-year project has demonstrated that university communication studies departments can be instrumental in helping community members cross organizational boundaries to engage in challenging dialogues when they are focused on engagement, facilitated by students, intentionally welcoming, and predictably organized.

Read less, learn more. Teach epistemic humility.
Authors: Admiraal Wilfried
Published: July 2024

Read less, learn more, sounds contradictory. I do not mean students should read less in general. PISA research (OECD, 2023) shows decreasing reading scores in many European countries, and reading literature is not only important for one’s reading competence, it also is fun. What I mean is what psychologist and philosopher William James already wrote in 1890: ¨The art of being wise is the art of knowing what to overlook¨ (James, 1890).

Authors: Natalia Kezia , Setiawan Andree Wijaya , Jayanti Ruth Meike
Published: July 2024

The Ralstonia solanacearum Species Complex (RSSC) is a significant plant pathogen affecting various agricultural commodities, including ginger. Understanding the distribution and characteristics of RSSC in ginger plants is crucial for effective disease management. This study aims to determine the distribution of RSSC in ginger plants and identify the pathogen through morphological and biochemical characterization. The research was conducted in Banyubiru and Getasan districts, Semarang Regency, Indonesia. The study involved purposive sampling, isolation, and purification of isolates, followed by morphological characterization through observation and biochemical characterization using Gram staining with KOH, oxidase test, arginine activity test, hypersensitivity test, bacterial density calculation, Koch's postulates, and biovar characterization. Three isolates from Banyubiru displayed typical morphological characteristics of RSSC, including round, mucoid colonies with red centers and white edges on TZC medium, and rod-shaped bacterial cells. Biochemical characterization identified these isolates as RSSC strains biovar 3 and 4, capable of causing bacterial wilt in ginger plants. The study confirmed the presence of bacterial wilt in ginger in Banyubiru district. The findings reveal the spread of bacterial wilt caused by RSSC in ginger plants in Banyubiru, Semarang Regency. There is a need for measures to control the potential spread of RSSC in the surrounding host plant areas in Tlumpak Village, Banyubiru district.
Efficacy of neem and basil leaf extracts in controlling whitefly (Bemisia Tabaci) infestations and enhancing yield in curly red chili peppers (Capsicum annuum L.)
Authors: Diputra Moses Graciano , Andree Wijaya Setiawan
Published: July 2024

Whiteflies (Bemisia tabaci) are a major pest of curly red chili peppers, acting as vectors for gemini viruses that significantly reduce crop productivity. This study evaluated the efficacy of neem and basil leaf extracts at three different concentrations for controlling whitefly infestations on chili plants. A randomized complete block design (RCBD) was employed with 8 treatments and 2 controls: PA (Neem 1%), PB (Neem 2%), PC (Neem 3%), PD (Basil 1%), PE (Basil 2%), PF (Basil 3%), PKM (commercial pesticide as positive control), and P0 (distilled water as negative control). Parameters assessed included whitefly infestation intensity, yellowing of shoots, fruit weight, total fruit count, and the number of infested fruits. The results indicate that both neem and basil leaf extracts effectively reduced whitefly infestation intensity and yellowing of shoots compared to the negative control (P0). Despite some increase in infestation intensity in subsequent observations, both neem and basil extracts positively impacted fruit yield, including higher fruit weight and total fruit count. However, there was no significant effect on the number of infested fruits with the treatments. These findings suggest that neem and basil leaf extracts are promising alternatives for managing whitefly infestations and improving yield in curly red chili peppers.
Combinatory effects of pineapple peel liquid organic fertilizer and rice husk charcoal on melon (Cucumis melo L.) growth and yield
Authors: Hidayat Moh. Hamdan , Lailiyah Wiharyanti Nur , Budi Setyo
Published: July 2024

The intensive use of synthetic fertilizers in melon cultivation can reduce soil organic matter and fertility, ultimately decreasing productivity. This situation necessitates the improvement of growing media to achieve production targets through the use of rice husk charcoal and liquid organic fertilizer (LOF) from pineapple peel. This study aims to determine the combinatory effects of pineapple peel LOF and rice husk charcoal media on the growth and yield of melon plants. The research employed a factorial randomized block design (RBD) with 6 treatment levels, and data were analyzed using ANOVA followed by an HSD test at the 5% significance level. The results showed an interaction between pineapple peel POC and rice husk charcoal media on the number of leaves variable. The P0M1 treatment (NPK 16:16:16 at 3 g and 50% rice husk charcoal & 50% soil) at 52 days after planting (DAP) produced the highest number of leaves, totaling 26.12. However, this increase in leaf number was not accompanied by an increase in fruit weight or brix levels. These findings open opportunities for further research to understand why the increase in leaf number did not translate to higher fruit weight or Brix levels, and to identify treatment combinations that can enhance both growth and yield.

Soil formation in volcanic terrains presents a significant challenge due to the diverse physical and chemical properties imparted by volcanic activity, which are not yet fully understood. This study investigates the unique morphological characteristics of soil profiles within crater topography sequences at the Tangkuban Parahu Volcano, Indonesia. To address this gap, five representative sample profiles (I, II, III, IV, V) were analyzed. The Ratu Crater pathway topography was characterized by steep to very steep slopes. Detailed analysis identified three predominant soil layers, each with distinct features such as color, texture, porosity, and chemical composition, reflecting different stages of soil formation. At the highest elevation near the crater rim, Profile V was composed mainly of volcanic ash, with a loose structure, high porosity, and acidic pH, indicative of recent volcanic deposits. Profile III, at intermediate elevations, consisted of highly weathered soil with sandy loam textures and clear layer demarcations, suggesting prolonged soil development and consolidation. Profile I, at the lowest elevation, featured loamy sand with significant weathering and organic matter incorporation, indicating advanced soil development stages. The findings underscore the impact of volcanic activity on soil morphology, revealing distinct layers that correlate with various ages and developmental stages. Understanding these processes can inform agricultural practices.

The formation of electric charges during the synthesis of complex oxide materials based on strontium hexaferrite SrFe12O19, including doped with lanthanum and cobalt ions, via the combustion of nitrate-organic precursors has been established. Precursors included polyvinyl alcohol or glycine as organic component. The intensity of charge generation was lower for precursors containing a larger amount of organic component. Data on the magnetic characteristics of the samples were obtained: magnetization, coercive force. The influence of an external magnetic field during the synthesis of hexaferrites significantly affected the coercive force of the samples and allowed to increase its values due to the formation of extended ensembles of nanoparticles. At the same time, such an effect on samples with a relatively low level of charge generation during precursor combustion was more effective. The relationship between the factors influencing the formation of extended aggregates is analyzed. The Sr0.8La0.2Fe11.8Co0.2O19 samples had the maximum coercive force. One of the techniques for increasing the coercive force is a two-stage thermomagnetic treatment, including a low-temperature stage. The formation of branched extended structures at the macro- and micro-levels was found during the combustion of glycine-containing precursors.

Published: July 2024

Using the method of pyrolysis of solutions in a melt, the phase formation of sodium and zirconium silicophosphates Na1+xZr2SixP3–xO12 was studied depending on the concentrations of sodium and phosphorus in the precursors. The influence of the content of these components, as well as firing conditions on the change in the ionic conductivity of NASICON was studied. Methods of X-ray phase analysis, scanning electron microscopy, full-profile Rietveld analysis, and electrochemical impedance spectroscopy were used. The specific values of grain conductivity (σb) and grain boundaries (σgb) of the samples were calculated. It was found that the reason for the change in ionic conductivity is a change in the composition of NASICON with increasing concentrations of sodium and phosphorus in the precursor. The main condition for high conductivity of the material is the formation of a crystalline phase corresponding to the composition Na3Zr2Si2РO12, as well as a minimum amount of impurities and glass phase. The conductivity of the NASICON sample (x = 2) under certain processing conditions is ~ 1 · 10-3 S/cm.

Zinc sulfide doped with Mn2+ ions was synthesized in a homogeneous dodecane medium by the method of emerging reagents. By methods of chemical and X-ray phase analysis, IR spectroscopy, electron microprobe microscopy, identification of products was carried out, photographs of the surface of powder particles (SEM) were recorded. Based on the totality of the results, a conclusion is made about the formation of nanoscale objects having a polytype structure with a predominance of distorted cubic crystals forming agglomerates up to 10 microns in size in ZnS powder and up to 100 microns in ZnS–Mn powder. The formation of nanoscale ZnS particles is confirmed by spectral data. The effect of manganese ions on the photoluminescence (FL) of the powder is manifested by a change in the type of the descending branch of the ZnS–Mn FL band, it is associated with recombination processes at the levels of defects formed by Mn2+ ions in the ZnS structure at their low concentration.

Zn(II) complexes of the composition [ZnLn2X2] and [ZnLn3(NO3)2] were synthesized, where n = 1, 2; X=Cl, Br, I; L1=2-aminothiadiazole-1,3,4, L2=2-amino-5-methylthiadiazole-1,3,4. The obtained complexes were studied by elemental analysis methods, IR and 1H NMR spectroscopy. The structure of the [ZnL22Br2] complex was determined by the RSA method (CIF file CCDC No. 2251742). The ligand molecules of 2-amino-5-R-thiadiazoles-1,3,4 (R = –H, –CH3) are coordinated monodentately by an endocyclic nitrogen atom located in the α-position to the amino group. The polyhedron of the central atom of halide complexes is a slightly distorted tetrahedron, in the coordination sphere of which two halide atoms and two endocyclic nitrogen atoms are located. During complexation in the spectrum of the solution of the [ZnL22Br2] complex, coordinated L2 ligands undergo amino-imine tautomerization into a heterocyclic amine with a nitrogen atom in a heterocycle. The polyhedron of the central atom for nitrate complexes is a slightly distorted trigonal bipyramide, in the coordination sphere of which three nitrogen atoms of ligands are located in the equatorial plane and two oxygen atoms of two nitrate anions in the axial position.

Copper (II) oxide nanoparticles are promising materials for applications in catalysis, biomedicine and photovoltaics. It is also possible to use them for the preparation of nanocomposites and hybrid nanoparticles. This work presents a new method for the synthesis of CuO nanoparticles, which allows their one-step preparation without washing and heating. The proposed anion-exchange deposition method is simple, fast and easily reproducible under normal laboratory conditions. It is shown that anion-exchange precipitation of copper in the presence of the polysaccharide dextran-40 from copper chloride and sulphate solutions produces well crystallised hydroxychloride Cu2Cl(OH)3 and hydroxysulphate Cu4(SO4)(OH)6, respectively, and from copper nitrate a weakly crystallised Cu(OH)2 phase. In the absence of polysaccharide, copper oxide nanoparticles are formed irrespective of the nature of the anion of the parent salt. The obtained materials were used to obtain hydrosols with high aggregation and sedimentation stability over a wide pH range (from 5 to 11). These sols are stable for more than 3 months at a concentration of 2 g/l (the average hydrodynamic diameter of the particles is 245 nm; the average ζ-potential is -31.1 mV). Based on the study of the optical and electronic properties of the obtained hydrosols, it was found that they could be of interest for photocatalysis and application in optoelectronic devices.

Ferrites of non-ferrous metals are promising magnetic catalysts that can be easily separated from the reaction mixture after use by applying a magnetic field. However, these materials have a fast electron-hole relaxation time, which reduces their activity in photoreactions. This problem is overcome by creating hybrid nanostructures based on ferrites, for example with zinc oxides. The catalytic activity of such structures depends highly on the method of their synthesis. In this work, the alkaline co-precipitation of Fe2+ and Ni2+ ions, which have similar values for hydroxides, was used to obtain stoichiometric and homogeneous nickel ferrite precursors. The influence of the reaction parameters on the purity of the nickel ferrite phase and the size of the particles was studied using the experimental design technique. Spherical nanoparticles 15.9 ± 1.1 nm in diameter were produced under the optimal conditions identified. Based on the obtained material, NiFe2O4/ZnO magnetic composites of different quantitative compositions were prepared. The photocatalytic activity of the hybrid structures was demonstrated by photodegradation of crystal violet dye.
