Medieval Manuscripts at Loyola University Chicago
Authors: Cornelius Ian , Young Kathy
Published: January 2024

Abstract: This article provides a summary overview of the collection of pre-1600 western European manuscripts in Loyola University Chicago Archives & Special Collections. The collection presently comprises four manuscript codices, at least thirty-eight fragments, and four documents. The codices are a thirteenth-century book of hours from German-speaking lands; a fifteenth-century Dutch prayer book; a preacher's compilation written probably in southern Germany in the 1440s; and two fifteenth-century Italian humanist booklets, bound together since the nineteenth century, transmitting Donatus's commentary on the Eunuchus (incomplete) and an anthology of theological excerpts, respectively. The fragments consist of thirteen leaves from books dismembered by modern booksellers (most are from fifteenth-century books of hours) and a larger number of binding fragments, all but two of which remain in situ. These represent the remains of ten manuscript books: four Latin liturgical books, two texts of Roman civil law, one large-format thirteenth-century Italian Bible, one thirteenth-century copy of Ptolemy's Almagest in the translation of Gerard of Cremona, one late fourteenth-century copy of the Ockhamist Tractatus de principiis theologiae , and one fifteenth-century Dutch book of hours in the translation of Geert Grote. Many of these materials have remained unidentified until now.
Fragmentation and Narrative Construction: The Cost (and Utility) of Fabricated Provenance
Authors: McCandless Rose A.
Published: January 2024

Abstract: The Josephinum Bible is a thirteenth-century bible manuscript exhibiting multiple forms of fragmentation, including the excision and replacement of many historiated initials and the commercial breaking of the manuscript into individual folios. It also contains evidence of manufactured provenance, primarily a forged document supposedly linking the manuscript to the Abbey of Saint Geneviève in Paris and dating it to the year "1247." Both the contrived date of the manuscript and supposed early link to the Abbey of Sainte Geneviève have been highlighted by various sellers of first the intact bible and later its broken, individual leaves to inflate the market value of the manuscript. Sellers cite these two pieces of "provenance," however, failing to question them, either tacitly or overtly encouraging buyers to draw incorrect conclusions about the true history of the manuscript. This article examines in detail for the first time the manuscript's manufactured provenance.
(Sin)vergüenza: El amor del revés de Luisgé Martín a la luz de la teoría de los afectos
Authors: Smuga Łukasz
Published: January 2024

Abstract: This article offers a new reading of Luisgé Martín's autobiography El amor del revés (2016) through the lens of affect theory, building on the writings of the American psychologist Silvan Tomkins and Eve Kosofsky Sedgwick's work on shame and periperformative utterances. A methodological framework proposed by the Polish queer theorist Tomasz Basiuk is used here to compare the configurations of shame in Martín's autobiography with the rhetorical strategies in American gay men's life writings. Performances of shame are foregrounded in the analysis as a salient feature of El amor del revés , in order to argue that they serve as a means to overcome the homophobia internalized by the generations of men who grew up in Spain under Franco's dictatorship. Borrowing Basiuk's key deconstructionist concept, exposure, which conveys the risk taken by gay authors in their autobiographical texts, I posit that Martín writes socially engaged literature, and that in doing so he relies on the coming-out narrative model typical for gay autobiographies to tell the story of his life. Yet he uses rhetorical strategies that reveal the constructedness of the story and of his sexual identity.
A Trilogy for the Defeated: Nonhuman Affect of Landscapes and Objects in Patricio Guzmán's Post-Transitional Documentaries
Authors: Zheng Nan
Published: January 2024

Abstract: Given the combative drafting process of a new Chilean constitution under the government of left-wing president-elect Gabriel Boric, this paper retrospectively analyzes three documentaries by Patricio Guzmán over the past decade—Nostalgia for the Light, The Pearl Button, The Cordillera of Dreams—to argue that they represent a post-transitional trilogy that departs from Guzmán's previous works during Augusto Pinochet's dictatorship and transition to democracy. Taking heed of Chile's extended cartography of disappearance of both indigenous minorities and political dissidents, this study steers away from human-centric critique of documentary historiography, instead delving into Guzmán's chronotopic presentations of two nonhuman actors: grand landscapes on the macroscale and small objects at the microscale. This paper demonstrates how their affective materiality, by running through and across human and nonhuman bodies, leads to excavations below History's surface, conjuring up small histories of the abovementioned two categories of los vencidos obliterated from postcolonial-ethnocentric and neoliberal-authoritarian imageries. Relying on non-representational methodology and theory of haptic visuality—respectively these destabilize human/landscape and human/thing dichotomies while converging on nonhuman affect—it proposes that it is through evocation of sensations that Guzmán's post-transitional aesthetics form diligent inquiries into the palimpsest of Chile's collective and individual counter-memories.
Principes Constitutionnels et Réalités Politiques, Administratives et Judiciaires au Maroc
Authors: Rousset Michel
Published: January 2024

RÉSUMÈ: La constitution marocaine de 2011 a été saluée pour les avancées importantes qu'elle réalisait en ce qui concerne l'Etat de droit et la sécurité juridique: Le Pouvoir judiciaire s'est substitué à l'autorité judiciaire d'antan et d'autre part la constitution promet la gestion du territoire dans le cadre d'une régionalisation effective permettant d'aboutir en cohérence avec action de l'Etat à la réalisation d'une équité territoriale qui actuellement n'est qu'un leurre comme l'a démontré hélas le séisme de septembre 2023 dans le haut Atlas .Or sur ces deux points la réalité apporte un démenti aux dispositions constitutionnelles. Pour le premier démenti il s'agit de la persistance d'un phénomène, ancien, la spoliation immobilière, malgré la protection constitutionnelle de la propriété privée qui existe dans toutes les constitutions depuis 1962; ce phénomène est lié à l'existence d'une véritable mafia composée d'agents immobiliers, des membres des professions judiciaires et oara-judiciaires, sans oublier sans doute de personnel de diverses administrations, notamment la Conservation foncière, le tout sur fond de corruption, maladie endémique au Maroc.
In-situ background-free Raman endoscope using double-cladding anti-resonant hollow-core fibers

Published: January 2024

This paper presents the development of an in-situ background-free Raman fiber endoscope, employing two customized double-cladding anti-resonant hollow-core fibers (AR-HCFs). The Raman background noise measured in the AR-HCF probe is lower than that of a conventional multi-mode silica fiber by two orders of magnitude. A plug-in device of fiber coupling optics is designed that is compatible with the commercially available confocal Raman microscope, enabling in-situ Raman detection. The numerical aperture (NA) of both AR-HCF claddings exceeds 0.2 which substantially enhances the collection efficiency of Raman signals at the distal end of the fiber probe. The performance of our Raman fiber endoscope is demonstrated by characterizing samples of acrylonitrile–butadiene–styrene (ABS) plastics, alumina ceramics, and ethylene glycol solution.
Deep causal speech enhancement and recognition using efficient long-short term memory Recurrent Neural Network
Authors: Li Zhenqing , Basit Abdul , Daraz Amil , Jan Atif
Published: January 2024

Long short-term memory (LSTM) has been effectively used to represent sequential data in recent years. However, LSTM still struggles with capturing the long-term temporal dependencies. In this paper, we propose an hourglass-shaped LSTM that is able to capture long-term temporal correlations by reducing the feature resolutions without data loss. We have used skip connections in non-adjacent layers to avoid gradient decay. In addition, an attention process is incorporated into skip connections to emphasize the essential spectral features and spectral regions. The proposed LSTM model is applied to speech enhancement and recognition applications. The proposed LSTM model uses no future information, resulting in a causal system suitable for real-time processing. The combined spectral feature sets are used to train the LSTM model for improved performance. Using the proposed model, the ideal ratio mask (IRM) is estimated as a training objective. The experimental evaluations using short-time objective intelligibility (STOI) and perceptual evaluation of speech quality (PESQ) have demonstrated that the proposed model with robust feature representation obtained higher speech intelligibility and perceptual quality. With the TIMIT, LibriSpeech, and VoiceBank datasets, the proposed model improved STOI by 16.21%, 16.41%, and 18.33% over noisy speech, whereas PESQ is improved by 31.1%, 32.9%, and 32%. In seen and unseen noisy situations, the proposed model outperformed existing deep neural networks (DNNs), including baseline LSTM, feedforward neural network (FDNN), convolutional neural network (CNN), and generative adversarial network (GAN). With the Kaldi toolkit for automated speech recognition (ASR), the proposed model significantly reduced the word error rates (WERs) and reached an average WER of 15.13% in noisy backgrounds.

Published: January 2024

Background

Falls contribute to impairments in activities of daily living (ADLs), resulting in significant declines in the quality of life, safety, and functioning of older adults. Understanding the magnitude and duration of the effect of falls on ADLs, as well as identifying the characteristics of older adults more likely to have post-fall ADL impairment is critical to inform fall prevention and post-fall intervention. The purpose of this study is to 1) Quantify the association between falls and post-fall ADL impairment and 2) Model trajectories of ADL impairment pre- and post-fall to estimate the long-term impact of falls and identify characteristics of older adults most likely to have impairment.

Method

Study participants were from the Ginkgo Evaluation of Memory Study, a randomized controlled trial in older adults (age 75+) in the United States. Self-reported incident falls and ADL scores were ascertained every 6 months over a 7-year study period. We used Cox proportional hazards analyses (n = 2091) to quantify the association between falls and ADL impairment and latent class trajectory modeling (n = 748) to visualize trajectories of ADL impairment pre-and post-fall.

Results

Falls reported in the previous 6 months were associated with impairment in ADLs (HR: 1.42; 95% CI 1.32, 1.52) in fully adjusted models. Based on trajectory modeling (n = 748), 19% (n = 139) of participants had increased, persistent ADL impairment after falling. Participants who were female, lived in a neighborhood with higher deprivation, or experienced polypharmacy were more likely to have ADL impairment post-fall.

Conclusions

Falls are associated with increased ADL impairment, and this impairment can persist over time. It is crucial that all older adults, and particularly those at higher risk of post-fall ADL impairment have access to comprehensive fall risk assessment and evidence-based fall prevention interventions, to help mitigate the negative impacts on ADL function.

Published: January 2024

Personal identification in forensics is possible with gender determination using DNA (deoxyribonucleic acid) analysis. DNA isolation from teeth samples subjected to extreme temperatures has been shown to predict the gender of the deceased. However, the literature lacks studies on DNA extracted from tooth samples exposed to freezing temperatures. This study aimed to isolate the SRY gene from the extirpated pulp of teeth that were subjected to varying temperatures for gender identification. Thirty teeth with vital pulps, divided into 3 groups were included in the study. Each group consisted of 5 male and 5 female tooth samples. The groups were exposed to diverse environmental factors for three weeks. Group 1: room temperature (R group); Group 2: high temperature (H group) and Group 3: freezing temperature (F group). Later, DNA was isolated from the pulp tissue, and the SRY gene was amplified using PCR (Polymerase Chain Reaction). The Sensitivity and Specificity of the results were analyzed. SRY gene detected in the study samples identified accurate gender with a 46.70% Sensitivity and 93.30% Specificity. Significant difference was found in the correlation between gene expression and gender among the three groups (p = 1.000). The study validates that dental pulp tissue can be a reliable source for DNA extraction. And SRY gene amplification from teeth exposed to diverse environmental conditions. Further investigations are required to validate its application in forensics.
High-altitude adaptation is accompanied by strong signatures of purifying selection in the mitochondrial genomes of three Andean waterfowl
Authors: Graham Allie M. , Lavretsky Philip , Wilson Robert E. , McCracken Kevin G.
Published: January 2024

Evidence from a variety of organisms points to convergent evolution on the mitochondria associated with a physiological response to oxygen deprivation or temperature stress, including mechanisms for high-altitude adaptation. Here, we examine whether demography and/or selection explains standing mitogenome nucleotide diversity in high-altitude adapted populations of three Andean waterfowl species: yellow-billed pintail (Anas georgica), speckled teal (Anas flavirostris), and cinnamon teal (Spatula cyanoptera). We compared a total of 60 mitogenomes from each of these three duck species (n = 20 per species) across low and high altitudes and tested whether part(s) or all of the mitogenome exhibited expected signatures of purifying selection within the high-altitude populations of these species. Historical effective population sizes (Ne) were inferred to be similar between high- and low-altitude populations of each species, suggesting that selection rather than genetic drift best explains the reduced genetic variation found in mitochondrial genes of high-altitude populations compared to low-altitude populations of the same species. Specifically, we provide evidence that establishment of these three Andean waterfowl species in the high-altitude environment, coincided at least in part with a persistent pattern of negative purifying selection acting on oxidative phosphorylation (OXPHOS) function of the mitochondria. Our results further reveal that the extent of gene-specific purifying selection has been greatest in the speckled teal, the species with the longest history of high-altitude occupancy.
Geometric analysis of non-degenerate shifted-knots Bézier surfaces in Minkowski space
Authors: Bashir Sadia , Ahmad Daud
Published: January 2024

In this paper, we investigate the properties of timelike and spacelike shifted-knots Bézier surfaces in Minkowski space-E13. These surfaces are commonly used in mathematical models for surface formation in computer science for computer-aided geometric design and computer graphics, as well as in other fields of mathematics. Our objective is to analyze the characteristics of timelike and spacelike shifted-knots Bézier surfaces in Minkowski space-E13. To achieve this, we compute the fundamental coefficients of shifted-knots Bézier surfaces, including the Gauss-curvature, mean-curvature, and shape-operator of the surface. Furthermore, we present numerical examples of timelike and spacelike bi-quadratic (m=n= 2) and bi-cubic (m=n= 3) shifted-knots Bézier surfaces in Minkowski space-E13to demonstrate the applicability of the technique in Minkowski space.
Mechanical properties of artificially structured soil and Binary-medium-based constitutive model under undrained conditions
Authors: Li Yizhi , Liu Enlong , He Miao
Published: January 2024

To investigate the mechanical properties and constitutive models of structured soil under undrained conditions, triaxial compression tests on initially anisotropic structured soil, isotropic structured soil, and remolded soil were conducted under consolidation undrained conditions at confining pressures of 25, 50, 100, and 200 kPa, respectively. The results demonstrate that the samples of structured soils with strong structural characteristics have an obvious yield strength when the consolidation stress is low. At this time, the pore water pressure in structured soils increases at the beginning of loading. As the axial strain increasing, it turns to reduce. When failure, the samples have obvious shear band. With the consolidation stress increases, the mechanical properties and deformation mechanism of structured soils are near to the remolded soil. Combining the Binary-medium theory with the analysis and discussion of the mechanical properties and deformation mechanisms of structured soil, the rationality of the corresponding Binary-medium model was verified, which shows that the constitutive model can reflect the characteristics of dilatancy and strain softening, volumetric contraction and strain hardening under the conditions of low and high confining pressure respectively. At the same time, the constitutive model can also reflect the differences in the stress-strain characteristics of the two structural soils caused by the structural differences. In general, the results agree with the experiment relative well.
Examining SEB skills’ incremental validity over personality traits in predicting academic achievement

Published: January 2024

Personality traits and social, emotional, and behavioral (SEB) skills share the same behavioral referents, but whereas traits refer to a person’s typical or average performance, skills refer to their capacity or maximal performance. Given their shared behavioral foundations, an important question to address is whether personality traits and SEB skills independently predict important outcomes. In this study (N = 642), we examined whether subscales of the Behavioral, Emotional, and Social Skills Inventory (BESSI), a measure of SEB skills, provided incremental validity in the prediction of the ACT composite score, an important academic outcome for American adolescents, over the Big Five personality traits. Consistent with our expectations, on average, SEB skills showed stronger associations with ACT achievement scores than personality traits. Moreover, SEB skills added incremental validity over and above personality traits in predicting ACT achievement scores. The findings reinforce the importance of conceptually distinguishing and measuring traits and skills.
Scholarly Rigour in Gelatin Silver: K. A. C. Creswell’s Photographs of Islamic Architecture
Authors: Seggerman Alex Dika
Published: January 2024

This article critically considers the aesthetics, process, and distribution of K. A. C. Creswell’s photographic collections of Islamic architecture. Creswell (1879–1974), a British university professor in Cairo from 1931 until his death, is considered one of the founders of the field of Islamic architectural history. As a young scholar in the 1910s, he took thousands of photographs of Islamic architectural sites, mainly in Egypt, which he then duplicated and deposited into major institutions of art historical study: Harvard University, the Victoria and Albert Museum, the Villa I Tatti, the Ashmolean Museum, and the American University in Cairo. While he strove to objectively document historical sites through photography, Creswell also inadvertently captured aspects of everyday life in the city of Cairo. These slips of modernity in his photographs highlight how he ‘personally re-created’ distinctive study images that are not solely documents of architecture. His choice of camera, lens, angle, shutter speed, lens filter, cropping, and printing generated an identifiable photographic style that marked these images within the field of art historical study. These five photographic collections, spread across three continents, thus exhibit how photography facilitated the incorporation of the field of Islamic art into the wider field of art history.

Looking at the Mediterranean as a geo-cultural space where people have met, assimilated, transformed and continue to do so, and at the relationship of cinema and media as representations of these ongoing movements and processes, the contributions of this Special Issue are pivotal in understanding the contemporary Mediterranean cultural identity. The authors’ analyses of a wide range of contemporary films and TV series from Egypt, France, Greece, Italy, Malta, Spain and Tunisia confirm that the Mediterranean identity does not belong to a group of sameness but to a group that embraces being and becoming. The guest editors, Giovanna Summerfield and Rosario Pollicino, intend to provide important reflections on the complexities of Mediterranean realities. Above all, their aim is to inspire and launch a dialogue between Mediterranean studies and media studies.
Quests for justice across the Mediterranean: Sorelle and *Zayy ish-Shams
Authors: Parolin Gianluca
Published: January 2024

Through the Egyptian remake of an Italian television series, the article explores the shared – and often overlooked – imaginaries of crime and its investigation that make such work possible across the Mediterranean and, in turn, cast light on broader imaginaries of law, and of the complex relations between citizens and law enforcement. In the Italian television drama Sorelle (Sisters) (2017), the sudden disappearance of her sister prompts the lead character to set off on a journey to solve this mystery. She is fortunate enough to have a close friend working in the police force, but in her struggle to conduct the investigations she is quite alone, and the Egyptian remake *Zayy ish-Shams (‘Like the sun’) (2019) echoes this sentiment. After considering how the two productions were presented within the dominant formats and genre characterizations, this article proceeds to situate them within the Italian and Egyptian formulas of crime drama and concludes that the Egyptian remake enables a new appreciation of an often-marginalized strain of Italian crime drama.
Representing the contemporary Mediterranean in La vie devant soi and La vita davanti a sé
Authors: Pollicino Rosario
Published: January 2024

This article focuses on the representation of the contemporary Mediterranean space in the films La vie devant soi (Madame Rosa) (1977), directed by Moshé Mizrahi and La vita davanti a sé (The Life Ahead) (2020), directed by Edoardo Ponti. Although the two films are adapted from the same novel, La vie devant soi (The Life Before US) (1977) by Romain Gary, they present different interpretations of the two main characters, Madame Rosa and Momo. This article argues how processes of (forced) movement of people – such as Holocaust deportation, postcolonial movements, and the current migrations between Africa and Europe – have demonstrated a contemporary ‘Mediterranean space’ that goes beyond its geographical borders, but rather is strictly linked to the people of the Mediterranean who made these movements. By analysing the cinematic Mediterranean space created in and in between these two films, it concludes that movement-induced traumas are intrinsic to the pragmatic existence of this geo-cultural space in contemporary times.

Potato starch plasticization by natural deep eutectic solvent
Authors: Skowrońska Dorota , Wilpiszewska Katarzyna
Published: January 2024

A natural deep eutectic solvent (NADES) based on choline chloride and malic acid was used to plasticize potato starch. The influence of starch gelatinization temperature, NADAES content and the method of its incorporation (before and after gelatinization) on starch plasticization was investigated. Polymer-plasticizer interactions were studied using MDSC, DMTA, XRD and FTIR-ATR methods. The viscosity of starch solutions as well as the mechanical properties and water absorption of the obtained films were determined. Gelatinization conditions had a significant impact on the viscosity of starch solutions and the physicochemical properties of the obtained films. The cross-linking reaction between starch and malic acid was confirmed by MDSC, DMTA, and mechanical properties. Slight recrystallization of starch was observed after 12 months of storage.

What Drives the Impact of Corporate Governance on Firm Value? Evidence from Earnings Management at Indonesian Sharia Stock Index (ISSI)
Authors: Erdin Maulana Tristianto  , Ridha M. Arsyadi
Published: January 2024

Purpose: This study sought empirical evidence on the impact of corporate governance as proxied by the board of commissioner's size, managerial ownership, and audit quality on firm value using earnings management as an intervening variable in energy sector companies indexed by the ISSI and listed on the Indonesia Stock Exchange from 2014 to 2022.
Methodology: This study uses purposive sampling technique and panel data, resulting in 171 selected sample data units that will be processed using eviews.
Findings: Managerial ownership, audit quality, and earnings management all have a significant and beneficial impact on firm value. However, the board of commissioners has a negative impact. Aside from that, the board of commissioners's size and managerial ownership do not affect earnings management, but audit quality has a negative effect. Earnings management as an intervening variable influences corporate governance variables.
 
Novelty: This research attempts to provide a novel viewpoint on how political instability in a country can affect the investment climate in the Indonesian energy sector, which has received little attention previously. This study also acknowledges the inconsistency of previous research findings regarding the relationship between corporate governance and firm value, paving the way for incorporating earnings management variables as mediators and ultimately contributing to our understanding of the complex dynamics between these elements.

Published: January 2024

Indonesia has abundant sources of renewable energy from ocean currents and waves, or a mixture of currents and waves at certain times to be used as an energy source for power plants. So at the Indonesian Hydrodynamics Laboratory, a study has been carried out to determine the performance of the Darrieus-type vertical axis turbine model to utilize the energy of ocean currents and waves. But the Darrieus Turbine with the turbine blades positioned perpendicular to the turbine axis cannot rotate if there is only wave force. Then several turbine models were made with the placement of the blades in an inclined position, to produce optimal rotor rotation in current conditions or a mixture of currents and waves. This paper describes the testing of 3 turbine models by varying the angle of inclination of the turbine blades (45°, 60°, and 75°), but still having the same turbine rotor area and giving different input currents and wave periods to produce the best efficiency and rotation in absorb current energy or a mixture of current and wave energy. The test results show that the 3 models of slanted blade turbines can absorb both wave and current energy, but turbines with 75° blade inclination produce the best performance compared to the others when exposed to currents and waves
Extracellular vesicles from obese and diabetic mouse plasma alter C2C12 myotube glucose uptake and gene expression

Published: January 2024

Recent studies have indicated a role for circulating extracellular vesicles (EVs) in the pathogenesis of multiple diseases. However, most in vitro studies have used variable and arbitrary doses of EVs rather than interpreting EVs as an existing component of standard skeletal muscle cell culture media. The current study provides an initial investigation into the effects of circulating EVs on the metabolic phenotype of C2C12 myotubes by replacing EVs from fetal bovine serum with circulating EVs from control mice or mice with obesity and type 2 diabetes (OT2D). We report that EVs associated with OT2D decrease 2‐NBDG uptake (a proxy measure of glucose uptake) in the insulin‐stimulated state compared to controls. OT2D associated EV treatment also significantly decreased myosin heavy chain type 1 (MHCI) mRNA abundance in myotubes but had no effect on mRNA expression of any other myosin heavy chain isoforms. OT2D‐associated circulating EVs also significantly increased lipid accumulation within myotubes without altering the expression of a selection of genes important for lipid entry, synthesis, or catabolism. The data indicate that, in a severely diabetic state, circulating EVs may contribute to insulin resistance and alter gene expression in myotubes in a manner consistent with the skeletal muscle phenotype observed in OT2D.

El artículo estudia el proceso de censura de la arenga cívica que escribió José María Lafragua con motivo de la celebración del 27 de septiembre de 1843 en la ciudad de México, así como la importancia de la prensa en la difusión de ideas y como medio de debate político en aquellos años. Considero a los discursos patrióticos del siglo XIX como discursos políticos tanto en su contenido como en su contexto; a partir de esto, postulo que el caso del político poblano se enmarcó en un proceso de censura “común” en aquella época pero, que al mismo tiempo, fue particular por el tipo de documento que fue objeto de un silencio forzado, algo inédito hasta ese momento.

Published: January 2024

When looking at spiritual and psychological counselling, the process, characteristics and problems, and the needs of the people involved in counselling, it can be seen that both of these non-material forms of assistance have a number of similarities, and also essential differences. This is to be expected, as both forms of assistance are categorised and treated as types of counselling. It is worth noting that in one form of counselling the focus is more on spiritual matters, while in the other the focus is on addressing a person’s psychological issues. A psychologist plays the role of a mirror for the individual, linking their well-being to active psychological efforts to help themselves, while a spiritual counsellor does not limit their activities solely to psychology and its techniques and knowledge, but seeks strength in the spiritual realm. By understanding the differences and similarities in the application of assistance methods, those seeking help can choose and seek the most appropriate form of assistance. Therefore, this article focuses on revealing the differences and points in common between spiritual counselling and psychological counselling, as ways to provide assistance to those in need. Although practitioners of counselling use the same or similar professional counselling skills, it is also important to note the fundamental differences, and to identify the values that practitioners of both spiritual and psychological counselling adhere to. In order to justify the distinctiveness and identity of spiritual and psychological counselling, the article aims to reveal the essence, the meaning, the differences, and the points in common between these forms of assistance.

Learning media is a vehicle for distributing messages and learning information which, if designed properly, will greatly help students achieve learning goals. The results of first observations made on students of SMA N 1 Boja, data obtained that only 50% of students remember virus content during X class, and there are more than 90% of students who have and bring Android smartphones to school which should be used for learning. While the results of interviews with biology teachers at SMA N 1 Boja class X, the difficulties in teaching virus content are the absence of teaching aids, content that tends to be abstract and students who tend to memorize rather than understand. Viruses are a content that is difficult to observe because of its form that cannot be seen with the naked eye because of its very small size. Mobile learning media is an innovation of learning media based on Android and information technology (IT) that can be used without the need for an internet connection and can be used anytime and anywhere to learn. Starting from the problem of abstract virus content and its small size so it cannot be seen with the naked eye, and the media used by the teacher is only power point, as well as the potential of students who already have and bring Android smartphones to school but have not been used optimally in learning, it is necessary to develop an android-based learning media, namely mobile learning.

Sampling using random sampling technique. In this study using the Pre Experimental Design method with One-Group Pretest-Posttest Design with a sample of class X MIA students at SMA N 1 Boja. The instruments used are: interviews, questionnaires and documentation.

Validation was carried out by a biology lecturer at Unnes and a biology teacher at SMA N 1 Boja with a score of >81% (very valid). A small-scale trial was conducted in class XI MIPA 1 with results >91% (effective), while the student and teacher questionnaire responses reached a score of >81%. A large-scale trial was carried out for class X MIPA 4 by conducting a pretest and posttest with classical completeness results >75% (effective). Thus the learning media for mobile learning virus content developed is feasible and effective to be used as a learning resource.

Lesson plans serve as guidelines for teachers when managing classes. However, some teachers choose to use the previous school year's lesson plans or copy their colleagues' lesson plans, this is due to the very detailed preparation of the 2013 curriculum lesson plans. This is the background for the Minister of Education and Culture to issue Letter Number 14 of 2019 concerning Simplification of lesson plan into three main components, namely learning objectives, learning activities, and assessment.. The purpose of this study was to analyze the ability of Biology Education Students in arrange the 2019 Revised lesson plan. The research method used was descriptive quantitative with survey techniques. The research sample was 50 UNNES Biology Education Students. Instruments in the form of lesson plan assessment sheets and student response questionnaires. The results obtained are the ability of Biology Students in general is included in the very good category by 14%, in the good category by 10%, in the average category by 44%, in the low category by 28%, and in the very low by 4%. Biology Education Students are mostly in the average category of 22 students. The total of students in the very good, good, and average categories is 34 students with a minimum score of 79,2. Most of the Biology Education Students in preparing the 2019 Revised lesson plan (34 students) have been able to compose the lesson plan components, especially the lesson plan identity components, learning objectives, selection of learning media, learning steps, assessment, and good language in preparing lesson plan. Although there are some students who have general deficiencies in the time allocation component that is not included in the learning scenario, learning resources that only use textbooks, lesson plans do not bring students closer to interacting with the environment, evaluations do not include remedial and enrichment programs, and assessment attachments are sometimes missed. The results of the student response questionnaires became crosscheck to determine the level of student knowledge .The result of learning objective percentage of 91.2%, an assessment of 90.8%, an evaluation of 89.2%, preparation and guidelines lesson plan 87.6%, learning steps 86.4%, basic knowledge about the differences between the 2013 Curriculum lesson plan and the 2019 Revised lesson plan 85.36%, knowledge about the advantages and disadvantages of lesson plan 84.13%.

The Covid 19 pandemic has reduced student learning outcomes. The decrease in learning outcomes is directly proportional to the decrease in learning interest. The reciprocal teaching model supports students to play an active role in learning with the teacher as a facilitator. The purpose of this study was to analyze the effect of the reciprocal teaching model on cognitive learning outcomes and students' interest in learning about environmental change and preservation at MAN 1 Semarang. This type of research is quasi-experimental with a non-equivalent control design. The sample in the study was determined by purposive sampling technique with X MIPA 3 as the experimental class and X MIPA 4 as the control class. Data on students' cognitive learning outcomes were measured using a test instrument and learning interest was measured using a questionnaire instrument. The results showed that there was a significant difference in the average cognitive learning outcomes in the experimental class compared to the control class with an average learning outcome of 83.89 > 73.47. The average increase in learning outcomes in the experimental class and control class is in the same category, namely moderate and significantly different with an N-Gain value of 0.46 > 0.33. The classical completeness of the experimental class was 91.67% and that of the control class was 61.11%. The experimental class gave a response that greatly increased interest in learning with an average percentage of 87.48% and the control class gave a response that did not increase interest in learning with an average percentage of 65.88%. The conclusion of this study is that the reciprocal teaching model has an effect on cognitive learning outcomes and students' interest in learning at MAN 1 Semarang.
