Mulheridades em Projetos de Extensão na Psicologia
Authors: Spaziani Raquel Baptista , Imbrizi Jaquelina Maria , Domingues Adriana Rodrigues
Published: September 2024

Resumo: A história da Psicologia no Brasil evidencia que esta ciência e profissão se consolidou vinculada aos interesses das elites, mas que transformações aconteceram no decorrer dos anos de 1970 devido, principalmente, aos esforços das teorias críticas e práticas contra-hegemônicas da Psicologia Comunitária e da Educação. Esses novos fazeres fortaleceram o compromisso ético-político com a transformação da sociedade e a categoria “classe social” passou a fazer parte de muitas análises críticas da área. Cabe, agora, questionar como a articulação classe-raça-gênero-geração, que abarca diferentes vivências, subjetividades e opressões, pode se presentificar nas ações e produções teóricas comprometidas com o enfrentamento das desigualdades sociais. O objetivo deste artigo é apresentar três experiências extensionistas intituladas “Mulheres, Arte e Cuidado”, “Escuta Clínico-Política Singular e em Processos Grupais” e “Narrativas Mambembes”, de modo a contribuir para as reflexões sobre as produções teóricas em psicologia acerca das relações desiguais de gênero e suas propostas de intervenção visando à construção de uma sociedade com condições igualitárias para todas/os. As experiências relatadas compõem o programa de extensão “Arte e Lugares de Escuta como Processos de Emancipação Política” desenvolvido na Unifesp, campus Baixada Santista, o qual considera a importância da criação de dispositivos de intervenção para que as pessoas possam ser cuidadas, acolhidas e contextualizadas sociopoliticamente. A partir disso, defendemos a inserção dos estudos interseccionais na produção de conhecimentos em psicologia, de modo a pluralizar os currículos de formação de psicólogas/os e visibilizar as perspectivas teórico-metodológicas elaboradas por mulheres.

Published: September 2024

ABSTRACT The purpose of the study was to determine the role and place of zhyrau poetry in world literature. The leading method in the course of the study was the method of direct analysis, which made it possible to study the phenomenon of zhyrau, its history of origin and formation, as well as the features of its application in literary creativity. In their songs, the zhyrau sang about the happy life of their people, their customs and everyday life. They praised beautiful girls and strong young men who will one day glorify the Kazakh people. Also, in the songs and poems there were historical campaigns, battles, which were an important part of the history of the people. Many poems and songs call for modesty, honesty, kindness, stigmatize greed, deceit, teach or just tell a story. Each work is a fragment from which the puzzle of the Kazakh culture is formed.

Published: September 2024

This work presents new information on the interaction of a promising biofuel - furan and the products of its
decomposition with molecular oxygen under conditions simulating combustion processes. The investigations were
carried out using the precision method of atomic resonance absorption spectroscopy on a high-purity shock tube
behind reflected shock waves in an ultra-dilute mixture of 10 ppm C4H4O + 10 ppm O2 in Ar in the temperature range 1600-4000 ± 50 K at pressures of 1.5-3 bar. During the oxidation of the studied fuel mixture time-resolved concentration profiles of the formation and consumption of atomic oxygen were obtained. Based on new experimental
data, the predictive efficiency of the modern kinetic model of biofuel combustion developed by the CRECK Modeling
Group was assessed, which was also used to demonstrate the key reaction pathways that determine the dynamics of
furan oxidation and the corresponding thermophysical processes under the studied chemical and thermodynamic
conditions. By comparing experimental and numerical data, a detailed analysis of the pathways for the formation
of products and the sensitivity of the rate constants of the occurring elementary reactions was carried out. As a
result, refinements to the rate constants of key reaction pathways were proposed and implemented, which significantly
increased the predictive abilities of the tested model. The accurate data obtained provide a valuable tool for verifying
new kinetic and thermophysical combustion models of multicomponent hydrocarbon fuel mixtures involving
promising biofuels.
Amorphous versus crystalline Al2O3 nanoparticles: a comparative study in photocatalytic dye degradation
Authors: Christan C. Seraph , Lukose Mary , Vijayan Karthikeyan , B. John Riya Alice , Vijayachamundeeswari S.P.
Published: September 2024

This study focuses on the synthesis of aluminum oxide (Al2O3) nanoparticles and compares their amorphous and crystalline phases, emphasizing their suitability for photocatalytic dye degradation. The as-prepared Al2O3, synthesized using the sol–gel technique, is found to have an amorphous nature, which is later annealed at 1200°C to obtain its α phase of crystalline nature. Despite the widespread applications of aluminum oxide in various fields, the differences between its amorphous and crystalline phases are not well understood. This work bridges this gap by evaluating the amorphous and crystalline phases of Al2O3, particularly for dye degradation. As technologies advance to enhance aluminum-containing photocatalytic materials by doping, composites, and hybrids, understanding the impact of material phase on photocatalytic capabilities becomes crucial. The research comprehensively assesses structural, functional, morphological, optical, and dye degradation characteristics. Remarkably, amorphous Al2O3 demonstrates superior dye degradation efficacy compared with its crystalline counterpart, achieving an enhanced degradation efficiency of 87.2% for rhodamine B, a commonly used azo dye in the printing and textile industries.
Numerical Flow Simulations of the Shear Stress Forces Arising in Filtration Slits during Glomerular Filtration in Rat Kidney
Authors: Fuhrmann Alexander , Pritz Balazs , Endlich Karlhans , Kriz Wilhelm
Published: September 2024

Key Points

Computational fluid dynamics were applied to estimate the shear stress challenge to the filtration barrier during glomerular filtration in rats.

Shear forces were especially relevant in pathologic situations where they contribute to the loss of viable podocytes.

Background

The flow dynamic forces during glomerular filtration challenging the fixation of podocytes to the glomerular basement membrane (GBM) are insufficiently understood.

Methods

Numerical flow simulations were used to estimate these forces in the rat kidney. Simulations were run with a three-dimensional (3D) model of the slit diaphragm as a zipper structure according to Rodewald and Karnovsky. The GBM was modeled as a porous medium.

Results

Filtrate flow exerted a mean wall shear stress of 39 Pa with a maximum of 152 Pa on the plasma membrane of foot processes and up to 250 Pa on internal surfaces of the slit diaphragm. The slit diaphragm accounted for 25% of the hydrodynamic resistance of the glomerular filtration barrier. Based on the results of the 3D model, we developed a two-dimensional (2D) model that allowed us to perform extensive parameter variations. Reducing the filtration slit width from 40 to 30 nm almost doubled wall shear stress. Furthermore, increasing filtrate flow velocity by 50% increased wall shear stress by 47%. When increasing the viscous resistance of the slit diaphragm, the pressure drop across the slit diaphragm increased to intolerably high values. A lower viscous resistance of the slit diaphragm than that of the GBM accounted for a gradual pressure decline along the filtration barrier. The subpodocyte space tempered these challenges in circumscribed areas of filtration surface but had only a marginal impact on overall forces.

Conclusions

The filtration barrier experiences high levels of shear and pressure stress accounting for the detachment of injured but viable podocytes from the GBM—a hallmark in many glomerular diseases.
Geochemical and mineralogical characterization and resource potential of the Namib Pb-Zn tailings (Erongo Region, Namibia)
Authors: Lohmeier S. , Gallhofer D. , Lottermoser B.G.
Published: September 2024

In Southern Africa, historic mining and mineral processing of base metal deposits have almost exclusively focussed on the extraction of major metals, leading to the loss of remaining valuable raw materials into tailings dumps and waste rock piles. At the Namib Pb-Zn mine (Erongo Region, Namibia), historic base metal tailings deposits are present as unreclaimed exposed waste piles. The tailings comprise silt- (fraction A: d50 = 25 to 48 μm) to sand-sized (fraction B: d50 = 86 to 185 μm; fraction C: d5o = 210 to 230 μm) material and contain major concentrations of base metals (Pb av. 1.15 mass%, Zn av. 3.20 mass%), S (av. 9.95 mass%), as well as lower values of other metals (Cu av. 490 μg/g, Cd av. 133 μg/g, Ag av. 22 μg/g), and critical elements like Sb (av. 14.7 μg/g) and In (14.3 μg/g). Former mineral processing only targeted the extraction of galena and sphalerite. As a consequence, qualitative mineralogical composition of the tailings is similar to that of the primary ore. Ca-Fe-Mg(-Mn) carbonates, quartz, micas, chlorite, minor graphite, magnetite, and rare parisite relate to the former host rock and gangue matrix, whereas Fe-rich sphalerite, galena, magnetite, pyrite with minor pyrrhotite, rare arsenopyrite, marcasite, cassiterite, and accessory scheelite are original constituents of the primary ore. Reprocessing of such a material would be challenging, but a mixed Pb-Zn concentrate enriched in Cd and Ag might be obtained. In future, possible reprocessing of Namib tailings and associated disposal of wastes into an appropriately designed repository would not only generate valuable metal commodities, but such activities would also eliminate a major metal pollution source from the local environment.
Influence of blasting charge distribution on the energy required for communition of rock
Authors: Seccatore J.E. , Cardu M. , Marin T.
Published: September 2024

The most energy-intensive process in the mining industry is particle size reduction - comminution. The first phase of this process is blasting to fragment the rock from the initial Boussinesq's half-space size. Scientific literature demonstrates that the output of a blast in terms of fragment size distribution can be manipulated by varying the specific charge (powder factor) and charge distribution. This study focuses on the influence of blasting on the internal resistance of the blasted fragments; in particular the influence of the spatial distribution of charges. Small-scale blasts were performed on 14 marble blocks using different powder factors and charge distributions. Three control blocks were fragmented by mechanical means for comparison. The results show the correlations between charge distributions and the specific energy of mechanical comminution. Opportunities for adjusting charge diameter and distribution in opencast blasts to improve the performancet of comminution circuits are discussed.
Valorization potentials of phosphate tailings at Minjingu mines in Northern Tanzania
Authors: Mdachi D.D. , Rugaika A.M. , Machunda R.L.
Published: September 2024

Sedimentary and igneous rocks are the two primary sources of phosphate that are mined and beneficiated to fertilizer. During the beneficiation process, phosphate is lost into the tailings. We investigated phosphate concentrations in tailings dumps at Minjingu mine, Tanzania using energy-dispersive X-ray fluorescence spectrometry to quantify the chemical compositions. The phosphate content in the tailings varied from 12.91% phosphorus pentoxide (P2O5) in Tailings 2 to 19.61% in Tailings Dump 1. The naturally occurring phosphate concentration in rocks ranges from 3% to 35%, and phosphate tailings from various locations with P2O5 concentrations as low as 6.46-12.65% have been beneficiated to commercial fertilizer. Our investigation revealed that phosphate concentrations in Minjingu tailings may be sufficient to be recovered for commercial applications. Suitable recovery methods are discussed, and we recommend that beneficiation should be performed to minimize the loss of phosphate into tailings. Further research is needed to identify the optimal beneficiation methodology.
Development of Best Practice Guideline for the management of hot holes in surface coal mines
Authors: Mpofu M. , Maphalala B. , Kgarume T. , Magweregwede F. , Stenzel G.
Published: September 2024

Surface coal operations in which mining activities are conducted above old underground workings experience hot holes after drilling. In a coal mine, hot holes are defined as shot holes, which after being drilled have an in-hole ambient temperature of 40°C or above or show a temperature increase of 3°C or more during monitoring. Hot holes and other cavities, such as cracks, pose health and safety risks to workers, such as exposure to hot air and high concentrations of noxious gases released from these holes. In addition, workers may be exposed to premature detonation of explosives caused by in-hole temperature increases and chemical reactions. To this end, Coaltech Research Association commissioned a project to develop a Best Practice Guideline for the management of hot holes. This paper is a compilation of the activities conducted in the development of the Best Practice Guideline between 2021 and 2022. The activities included a review of standard operating procedures and hot-hole temperature-measuring and -monitoring devices, and the assessment of current hot-hole procedures at selected mines. The results indicated that management of hot holes requires a focus on pre-emptive risk assessment of mining blocks, identification of hot holes using the correct temperature-measuring devices, and continuous monitoring of hot holes from the time of drilling until just before blasting. Hot-hole management accessories, such as polyvinyl chloride sleeves, were found to be effective in insulating the hot-hole emulsion from the rock mass temperature, thus preventing the potential for premature detonation.
Technical examination, elemental analysis and conservation of the arm of a colossal bronze statue from Aegion at the conservation laboratories of the National Archaeological Museum at Athens
Authors: Moraitou Georgianna , Gerasimos Makris , Pantelis Feleris , Georgios Kouros
Published: September 2024

The bronze arm, belonging to a colossal statue (presented by A. G. Vordos in this volume), was examined at the Chemical-Physical Research & Archaeometry Laboratory of the National Archaeological Museum (NAM) in Athens. According to prevailing methodology the examination comprised: macroscopic, microscopic and endoscopic examination, elemental analysis p-XRF, X-ray radiography, recording of ancient repairs. It is assumed that the arm was manufactured by the indirect lost wax casting technique and was found to contain an enormous amount of lead (av. 40.15 %), a fact that dates it to the late Hellenistic or Roman period. The arm was consequently conserved at the Metal Conservation Laboratory of the NAM and it has now been returned to the Ephorate of Antiquities of Achaia in Patras
Die Herakles-Kentauren-Gruppe
Authors: Stoss Stephanie
Published: September 2024

The bronze candelabrum found in 1896 during the Austrian excavations in the ›Marble Hall‹ of the Harbour Gymnasium in Ephesus, which shows a group with two persons—Herakles fighting with a Centaur—in front of a tree, has been part of the collection of antiquities of the Kunsthistorisches Museum Vienna since the end of the 19th century. In the course of recent research, questions concerning the history of the find and the object, technical aspects and modern restoration measures, as well as the dating and the original context of the installation were addressed. Scientific analyses were carried out, which helped to identify one of three other fragments present, a horse’s front hoof, as belonging to the group. A second human foot and a horse hind leg indicate that there was a second group of the same size. This one, however, was not quite identical as assumed in previous research, but probably showed a similar motif—maybe the hero kneeling on the centaur. Stylistic and technical aspects point to a dating in late Hellenistic times, in the middle of the 1st century BC, and eventually to a workshop in Alexandria. It is therefore possible that this is the oldest preserved bronze candelabrum of this form.
Bronzi figurati romani dal territorio di Mantua, Italia
Authors: Bolla Margherita
Published: September 2024

Roman Figural Bronzes from the Territory of Mantua, Italy. In recent years, many discoveries have been made in the country around Castel Goffredo, in the province of Mantua (Northern Italy). These are Roman small objects mainly in bronze, iron, lead, as they were found with the use of metal detectors. For this reason, the context of provenance is often unknown and the analysis of the finds is difficult. The knowledge of these objects was deepened following the setting up of the new archaeological section of the Museum of Castel Goffredo (MAST), inaugurated in June 2021.
The Roman figural bronzes found in this territory are presented here. The remains of a lararium, including an interesting statuette of Aesculapius, has been examined in the typological framework of the bronze representations of this god.

Published: September 2024

The Winged Victory (Vittoria Alata) of Brescia is one of the most important Roman bronzes in Italy. Discovered in 1826, it dates back to the 1st century AD. Since the 19th century the statue has undergone multiple conservation interventions. The last one started in 2018 up to 2020. The project was defined with a multidisciplinary approach which made it possible to study and compare the data obtained from the restoration with those deriving from scientific analyses, humanistic studies and other specialist research. For the first time after the discovery, it was possible to explore the internal surfaces of the statue and acquire very important data for the technological study of the work. Particular attention was paid to cleaning the surfaces; once the materials accumulated over time were removed, partly residues of past interventions, it was possible to rediscover the beauty of the face, the refinement of the modeling and the high peculiarity of the wings. New technological solutions have been studied for the internal support that replaced the one inserted in the nineteenth century to hold the arms and wings of the statue, as it was no longer suitable for guaranteeing the safe conservation of the work. Since October 2020, the Winged Victory has been exhibited in the renovated Capitoline temple in Brescia, where it was discovered.
New find of Roman military equipment of the period of the Roman–Bosporan war of 45–49 AD from the Eastern Crimea
Authors: Treister Mikhail Yu. , Vinokurov Nikolay I.
Published: September 2024

The Artezian fortified settlement in the Azov Sea coast of Eastern Crimea perished in a strong fire at the beginning of the Roman–Bosporan war in 46/47 AD. In the homogeneous fire layer, along with numerous items of jewellery, silver, bronze and glass vessels, a heavily burned out round bronze plaque, 7.7–7.8 cm in diameter with a hole in the centre was found. The plaque is decorated along the edge with a figural frieze, depicting two pairs of animals opposing each other: ‘dog–bull’, ‘dog–wild boar’. Besides two animals are running after each other: a lion and a roe deer.
The decoration of the plaque from Artezian finds parallels among plaques from the military camps along the limes of Lower and Upper Rhine and Danube. Objects similar in shape depicting animals in circular friezes are also known in Dacia and in the South-Western Crimea. The parallels to the images of the plaque and options of interpreting the function of the piece are discussed. The combination of pairs of opposing animals and animals running after each other finds parallels only on the belt plaques from Asciburgium and Magdalensberg. Thus, there are reasons to consider the disc from Artezian as an element of Roman military equipment of the first half of the 1st century AD.

Bronze casting in Late Antiquity in the Marche Region
Authors: Frapiccini Nicoletta
Published: September 2024

This essay reviews the discovery of three sites where deposits of bronze fragments have been found, in the Roman cities of Pisaurum, Sentinum and Potentia. Each site yielded small bronze fragments and some tools, which lead us to suppose that these were sites of Late Antique foundries, where large bronze statues and other bronze objects were broken up to be remelted. The foundries were located on land previously occupied by taverns in the forum area or by residential quarters. This means that the urban plan of the cities had already been partially transformed, probably due to Christianisation and the construction of churches, which became the new community centres, to the detriment of the older areas of the forum. The rampant poverty and shortage of raw materials, especially metals, made foundries indispensable and, consequently, their widespread presence, even within the cities, probably became customary. Perhaps the numerous bronze fragments found in other centres of the region should also be interpreted in this same sense, as indications of foundries, even if the structures where the metal was worked have not been preserved.

A group of very significant Lombardic ornaments from the cemetery of San Mauro at Cividale del Friuli (Udine) in Italy has been examined and analysed with X-ray fluorescence spectrometry. The objects are now part of the collections of the National Museum of Cividale del Friuli. Among the objects there are several so-called stirrup or radiate-head bow fibulae, one of which also shows an interesting cloisonné decoration, an S-shaped fibula with cloisonné, a unique gilded and nielloed equal-armed fibula with two opposite faces or masks, belt buckles and belt plates, a necklace with gold pendants with filigree and granulation, a vessel of probable Byzantine origin and a golden cross. The composition and the production technology of the single pieces are discussed in detail in the paper with relevant comparisons.
Tooth for tooth
Authors: Peltz Uwe
Published: September 2024

Until the Hadrianic period, large bronzes had a naturalistic appearance due to polychrome elements. One element on the statues of gods, heroes and portraits that has been studied rarely are the inserted white teeth. They were invented in the late archaic or early classical period and disappeared on the large statues with the decline of the Hellenistic foundry art. Usually the upper incisors where visible behind the opened lips.
The upper front teeth—and sometimes the lower once—were made of white metal (silver plating, tinning), light stone (marble), or more appropriately, bone (bone, ivory, tusks). It was still able to reconstruct four variants with several variations used for the installation of teeth in the open mouths. They could be fixed with glue. Other options consisted of hanging rows of teeth on hooks and brackets. In addition, the teeth rows were mounted in front of and on tooth backplates. Often, the installation of teeth was carried out in combination with the fitting of red lips.
Some techniques for producing copper wire in late Classical and Hellenistic Macedonia
Authors: Jeffreys Rosemary A.
Published: September 2024

This paper discusses different techniques for making copper wire in the fourth and third centuries BCE in ancient Macedonia (Northern Greece). Wire was used to form stems on gilded wreaths, and to support berries, leaves and rosettes. Stems were made in one piece with the leaves, and are likely to have been formed in at least two ways: one involved cutting them out of sheet copper about 0.5 mm thick, which was creased and then hammered into shape; the other involves using copper rods 1mm square. Some of the square copper rods can be seen on the wreaths, and their regularity suggests they may have been formed on a swaging block. Berries were joined to the wreath circlets by round wires, formed in some cases, it is suggested, by hammering sheet metal around a central core; in other cases, these stems may have been formed by rolling a rod between stone slabs. No evidence, such as longitudinal striations, was found of drawing. Some examples of strip-twisted wire were found, but there are fewer cases of this than of wire formed by hammering. The most expensive gilded wreaths at Derveni, cist grave A, Phoinikas cist grave 5 and Sedes, sometimes had special features, such as gilded copper tubes (‘branches’) with smaller stems on either side, or square wires formed into spirals.

This article theoretically and experimentally proves the expediency of replacing apple puree of the trademark with mashed fresh apples in souffle technology, as well as the use of food agar as a stabilizer, and natural honey as a sweetener. According to the results of organoleptic indicators, an improvement in the consistency of the finished product is observed, the souffle structure becomes more dense and porous. The color of the product changes from gray to milky cream, that increases the consumer quality of the products. In terms of physico-chemical and microbiological parameters, the souffle meets the requirements of regulatory and technical documentation and TR CU 021/2011. Due to the natural proteins in natural honey, there is an improvement in the foaming ability of the souffle, and the foam is characterized by a denser and more stable structure. In addition, with the addition of natural honey, the viscosity of the product increases, which indicates its stabilizing properties.
India and the Indo-Pacific in the Post-Pandemic World Order
Authors: Vinodan C. , Alexander J.K.
Published: September 2024

Indo-Pacific is a geopolitical construct that combines the Indian Ocean and the Pacific Ocean, representing the new strategic reality of the twenty-first century. Indo-Pacific is also considered significant for countries as it is a strategic and economic domain with a critical role in maritime security and cooperation. With a strategic location in the Indo-Pacific region, India is now a theatre of opportunity to increase its role regionally and globally. The Indian Ocean carries 90 per cent of India’s trade and its energy sources, and nearly 50 per cent of India’s trade is centred in the IndoPacific region. India’s relations with incredible powers, island nations, and smaller littoral states will significantly shape India’s Indo-Pacific strategy. Increasing non-traditional threats and growing challenges from rising China are significant drivers of India’s policy options in the post-pandemic world. India’s soft power diplomacy and bilateral and multilateral partnerships in the region continue to be decisive factors for security and balance of power in the post-pandemic scenario. Thus, the geo-strategic environment of the Indo-Pacific in the post-pandemic era is crucial for India and the countries in the Indo-Pacific region as a whole for their growth, development, and security. Thus, this paper explores India’s crucial role in ensuring the security and equilibrium of the post-pandemic Indo-Pacific through a comprehensive analysis of its strategic initiatives and regional dynamics.
Characterizing Lithospheric Transverse Isotropy Using Moment Tensors—On the Origin of the Non–Double-Couple Components of Global CMT Solutions
Authors: Kawakatsu Hitoshi
Published: September 2024

The seismic moment tensor, which represents the equivalent body-force system of the seismic source, may exhibit non–double-couple components (NDCs) when the earthquake occurs on a planer fault if the source medium is anisotropic. Kawakatsu (1991a) reported that the NDCs of the moment tensors (MTs) for shallow earthquakes from the Harvard Centroid Moment Tensor (HCMT) catalog exhibited a systematic characteristic dependent on faulting types: the sign of the NDC parameter ϵ on average systematically changes for thrust fault (TF) (negative), normal fault (NF) (positive), and strike-slip (SS) (positive) fault. The behavior of TF and NF that shows opposite sign can be explained if the source region is transversely isotropic with a vertical symmetry axis (VTI, radially anisotropic). In fact, the VTI model of the Preliminary Reference Earth Model (PREM) at a sub-Moho depth predicts the observed systematic NDC pattern, although the magnitude is underestimated, indicating the potential to enhance our understanding of the lithospheric transverse isotropy using the NDC of the MTs. To investigate the lithospheric transverse isotropy structure using the NDCs of the MTs, we propose a novel inversion scheme, building on the approaches used previously for deep and intermediate-depth earthquakes but with necessary modifications to address shallow sources. Synthetic tests conducted under conditions of random faulting indicate the potential to constrain the S-wave anisotropy ξ and the fifth parameter ηκ, but with moderate to severe correlation depending on data types. The application of this method to real data sourced from the Global Centroid Moment Tensor catalog suggests that the lithospheric transverse isotropy of PREM at the sub-Moho depth serves as a suitable initial model. However, some adjustments may be necessary, particularly regarding the fifth parameter, to enhance the model’s fidelity in representing observed NDCs of the MTs. Finally, the behavior of the SS faults that cannot be explained by the VTI may deserve further attention.

Aristoteles’in Tarih Algısının İbn Haldûn’un Tarih Felsefesi İle Benzerliği Üzerine Bir İnceleme
Authors: Serdar Murat , Köse Sami Okan
Published: September 2024

Tarih felsefesi en basit tanımıyla tarihin felsefi bir zihinle telakkisi, bir nevi felsefileştirilmesi veya felsefileştirilmiş halidir. Genel kabul, tarih felsefesini isim olarak ilk dillendirenin Voltaire ve kurumsal manada bir disiplin haline sokan kişinin de Vico olduğu üzerinedir. Her ne kadar genel kabul bu yönde olsa da aslında bu iki isimden çok daha önce ilk olarak Aristoteles ve sonrasında da İbn Haldûn, çeşitli yöntem ve söylemlerle tarihin ancak felsefi bir mahiyete bürünmek suretiyle değer ve anlam kazanacağı minvalinde bir yaklaşım ortaya koymuştur. Böylelikle de tarih felsefesinin ilk nüvelerinin oluşturulmasına katkıda bulunmuşlardır. Aristoteles ve İbn Haldûn’un tarih anlayışlarını veya tarih felsefelerini karşılaştırmayı amaç edinen bu çalışma; hem Aristoteles’in hem de İbn Haldûn’un aralarındaki birtakım basit nüansların sayılmaması halinde, tarihin, sadece felsefi bir karaktere sahip olmakla kıymetli olabileceği düşüncesinde hemfikir olduklarını ortaya koymaktadır.

Published: September 2024

Afetlerin etkileri sadece insanlarla sınırlı olmayıp, yaşanan afetler hayvanlar için de bir risk unsurudur. Günümüzde, hayvan hakları konusu afet planlarında ihmal edilmektedir. Çalışma, Türkiye’deki afet yönetim sistemini hayvan hakları açısından değerlendirmeyi amaçlamaktadır. Çalışmada afet yönetimi ve hayvan haklarına ilişkin uluslararası politika belgeleri, yasal düzenlemeler, planlar, programlar ve uygulamalar incelenecektir. Yapılan çalışmada Türkiye’de afet yönetiminde ulusal düzeydeki politika belgelerinin, hukuki düzenlemelerin insan odaklı bir bakış açısına sahip olduğu, afet öncesi, sırası ve sonrasındaki çalışmaların yeterli olmadığı tespit edilmiştir. Çalışmada, afet yönetim sisteminin sadece insan odaklı değil, hayvanlar da dâhil tüm yaşam formlarının eşit derecede yaşama ve kendini gerçekleştirme hakkına sahip olması gerektiğine vurgu yapılacaktır. Afet yönetim sürecine hayvan hakları konusunun dâhil edilmesi, insan-hayvan refahlarını destekleyerek çevresel ve sosyal adaletin gerçekleşmesine, afet yönetim sürecinin başarısına katkı sağlayacaktır.

Araştırmada ilişkisel tarama deseni kullanılmış ve bu amaç doğrultusunda basit bir aracılık modeli oluşturulmuştur. Anket, Batman ilinde ikamet eden 14-18 yaş aralığındaki ergen bireylere uygulanmış ve toplam 546 anket üzerinden analiz yapılmıştır. Analiz sonuçlarına göre algılanan sosyal destek, boyun eğici davranış (r = -0.217, p < 0.01) ve akran zorbalığı mağduriyeti (r = -0.194, p < 0.01) ile negatif bir korelasyon göstermiştir. Aynı şekilde boyun eğici davranışın, akran zorbalığı mağduriyeti ile pozitif yönde (r = 0.300, p < 0.01) ilişkili olduğu belirlenmiştir. Algılanan sosyal desteğin akran zorbalığı mağduriyeti üzerindeki etkisinde boyun eğici davranışların aracılık etkisi incelendiğinde standartlaştırılmış dolaylı etkinin anlamlı olduğu görülmüştür (β = -0.059, p < 0.01). Sonuç olarak elde edilen veriler perspektifinde algılanan sosyal desteğin akran zorbalığı mağduriyeti üzerindeki etkisinde boyun eğici davranışların aracı rol oynadığı ortaya çıkmıştır.

Teknolojik Gelişmenin İstihdam Üzerindeki Etkisi: G-20 Ülkeleri Panel Veri Analizi
Authors: Tunçsiper Çağatay
Published: September 2024

Teknolojik gelişmeler, Sanayi Devrimi'nden bu yana yoğunlaşan bir eğilim olarak işgücü piyasalarını önemli ölçüde etkilemiştir. Bu çalışma, 1996-2021 yılları arasında G-20 ülkelerinde teknolojik gelişmelerin istihdam üzerindeki etkisini incelemektedir. Yıllık veriler kullanılarak, bu ilişkiyi değerlendirmek için bir panel regresyon modeli kullanılmıştır. Modelde, istihdamın nüfusa oranı bağımlı değişken, Ar-Ge harcamaları ise bağımsız değişken olarak teknolojik gelişmeyi temsil etmektedir. Ayrıca modelde Gayri Safi Yurtiçi Hasıla'nın (GSYH) büyüme oranı ve patent başvurularının sayısı (hem yerli hem de yabancı) gibi kontrol değişkenleri de yer almaktadır. Ampirik bulgular, Ar-Ge harcamalarının istihdam üzerinde pozitif ve istatistiksel olarak anlamlı bir etkiye sahip olduğunu, patent başvuru sayısının ise negatif ve anlamlı bir etki yarattığını ortaya koymaktadır. Ayrıca, GSYİH büyümesinin istihdam seviyelerini pozitif ve anlamlı bir şekilde etkilediği bulunmuştur.
