Authors: Koç Ümit
Published: December 2024

Bu çalışmanın temel amacı cari işsizlik oranını ayrıştırarak doğal işsizlik oranlarının tespit edilmesidir. Bu kapsamda seçili gelişmekte olan ülkeler 2001-2022 dönemi stokastik sınır yaklaşımı kullanılarak ampirik olarak incelenmektedir. İktisadi teori cari işsizlik oranını friksiyonel, yapısal ve konjonktürel işsizliğin toplamı olarak ayrıştırmaktadır. Ayrıca teorik yaklaşımlar friksiyonel işsizlik ve yapısal işsizliğin toplamının doğal işsizlik (NRU) olarak adlandırılan bir denge işsizlik kavramına karşılık geldiğini de ifade etmektedir. Bu noktadan hareketle bu çalışmada friksiyonel (geçiçi) işsizlik oranı sıfır kabul edilerek, cari işsizlik oranı doğal işsizlik oranı ve konjonktürel işsizlik oranı olarak ikiye ayrıştırılmaktadır. İşsizliğin bileşenlerini elde ederken literatür kullanılan en yaygın yöntem tek değişkenli istatistiksel filtreler olmaktadır. Bu filtrelerin başında şüphesiz HP filtresi gelmektedir. Çalışmada, tek değişkenli istatistiksel filtre sonucunda hesaplanan doğal işsizlik oranının stokastik sınır yaklaşımı sonucu ulaşılan değerlere kıyasla daha yüksek olduğu gözlemlenmektedir. Doğal işsizlik değerlerinin literatürde tahmin edilenden düşük olması, konjonktürel işsizliğin daha önce düşünülenden daha yüksek olabileceğini göstermektedir. Bu durumda politika yapıcılara aktif para ve maliye politikalarının uygulanması açısından daha geniş bir alan oluşturmaktadır.

İKTİSAT POLİTİKALARIN ETİK VE SİYASET ÜZERİNDEKİ ETKİSİ
Authors: Alpago Hasan
Published: December 2024

Klasik iktisat öğretisinde ekonomi politikaları pozitif ve normatif olarak sınıflandırılır. Pozitif ekonomi kar, zarar, maliyet, gelir, gider gibi girdi ve çıktı hesabına dayalı salt ekonomik saiklere göre izlenen iktisat politikalarını temel alırken, buna karşılık normatif ekonomi bakış açısı etik, inanç, sosyokültürel değerlerin iktisadi karar alma süreçlerindeki etkisini ele alır. Ayrıca ekonomik kararlar gerçekçilik ve isabetlilik derecelerine göre uygulanabilirlik kazanmaktadır. Bu çerçevede bakıldığında iktisat politikaları nihai olarak kıt kaynakların sonsuz ihtiyaçlar karşısında mevcut veriler ışığında doğru ve etkili bir şekilde değerlendirmesini esas alır. İktisat politikaları aynı zamanda karar vericilerin aldıkları kararların etik ve siyasi sonuçlarını da dikkate almasını gerektirmektedir. Nitekim iktisat tarihi boyunca iktisat teorileri kıt kaynak yönetiminde etkin bir role sahip politik süreçlerde ileri sürdükleri teorilerle yön vermeye çalışmıştır. Smith, Marx, Keynes ve bunların ekseninde yer alan sosyal bilimciler bu açıdan yaptıkları çalışmalarda doğrudan politik karar vericilere bir ülke, toplum veya şirketin ekonomik kaynak yaratma ve yönetmede nasıl bir yol izlemeleri gerektiğini çeşitli çalışmalarla formüle etmişlerdir. Bu çerçevede Smith liberal bir politikayı önerirken, Marx devletin işçi sınıfı eliyle kontrol ettiği merkezi bir iktisadi sistemi savunmuştur. İşte bu çalışma iktisat politikalarının siyaset ve yönetim üzerindeki etkilerini ekonomik ve ahlaki değerlere göre analiz etmektedir.
L.T. HOBHOUSE PERSPEKTİFİNDEN SOSYAL LİBERALİZMDE DEVLET-BİREY İLİŞKİLERİ
Authors: Acar Eray
Published: December 2024

Sosyal liberalizm, toplumların gelişiminde önemli bir etkiye sahiptir ve bireylerin özgürlüğü ile eşitliği üzerine yoğunlaşmaktadır. Bu doğrultuda, Leonard Trelawny Hobhouse'un fikirleri sosyal liberalizmin temel değerleri arasındadır. Liberal gelenekten gelen Hobhouse, bireylerin ekonomik özgürlüğün yanı sıra sosyal haklara da sahip olması gerektiğini belirtir. Toplumsal iyilik durumunun bireylerin refahıyla doğrudan bağlantılı olduğunu öne sürer. Bu görüşler, modern devletin rolünün sadece yasalarla sınırlı kalmayıp, sosyal dengeleri de gözetmesi gerektiğini ortaya koyar. Sosyal liberalizmi savunarak klasik liberalizmin eksik kalan toplumsal boyutunu önceleyen Hobhouse'a göre; sosyal liberalizm anlayışı, bireylerin potansiyellerini gerçekleştirmelerine izin verirken, adil bir toplum yapısının da oluşturulmasına katkı sağlar. Özellikle günümüzün liberal kapitalist sistemlerinin ortaya çıkardığı sosyal dengesizlik, yoksulluk ve refahın adil paylaşılmasına ilişkin problemlerin giderilmesine yönelik çözüm arayışlarında tekrar gündeme gelen sosyal liberalizm bu çalışmada, Hobhouse'un sosyal liberalizmiyle ilgili temel fikirlerini incelenmesi ve bu düşüncenin günümüzdeki yansımaları ele alınmaya çalışılmıştır.

Published: December 2024

In line with emerging trends, the sports nutrition industry actively seeks cost-effective and health-promoting protein ingredients to replace animal-derived products and transition toward more sustainable practices. Protein concentrates derived from legumes, including peas, have attracted consumer interest due to their rich amino acid profiles and favourable functional properties. Our research aimed to develop and optimise an enzymatic technology for producing protein hydrolysates from locally adapted pea varieties in Kazakhstan. Based on the research findings, optimal technological conditions for protein extraction from peas via enzymatic methods were established: pea flour-to-water ratio (hydromodule) 25%; duration of water extraction 24 hours; concentration of added pepsin enzyme 4.0%; pepsin fermentation time 24 hours; concentration of added pancreatin enzyme 4.0%; pancreatin fermentation time - 5 hours. A pilot batch of enzymatically hydrolysed pea protein concentrate was produced under laboratory conditions, and analyses were performed on the resulting concentrate derived from the Aksary pea variety. The protein concentrate contained 8.92% crude protein and 5.38 ± 0.02 mg/mL amino nitrogen. Notably, due to the amino acid L-arginine at 0.540±0.216% and lysine at 0.587±0.199%, the hydrolysate can be utilised as a component of sports supplements to support muscle mass development. This work was conducted as part of the project "Development of a technology for producing protein-vitamin concentrates based on plant raw materials for sports nutrition" within the framework of the scientific-technical program BR22886613, titled "Development of Innovative technologies for the processing and storage of agricultural crop production and raw materials". The project is funded under the 267-budget program "Enhancing the accessibility of knowledge and scientific research", subprogram 101 "Program-targeted financing of scientific research and activities" of the Ministry of Agriculture of the Republic of Kazakhstan for 2024–2026.

Authors: Bozhkov Petko , Grigorov Borislav , Saraffov Alexander
Published: December 2024

The following study examines the content and composition of soil organic carbon (SOC), focusing on the fractions of humic and fulvic acids under different vegetation types in Ruy Mountain, located in SW Bulgaria. Soil samples from surface horizons (0–10 cm) were analyzed to determine the total carbon, organic carbon, and the ratio of humic to fulvic acids. Results show significant variation in SOC, with the highest levels in soil under Fagus sylvatica (beech) forests and the lowest under Pinus sylvestris (pine) forests. The humic to fulvic acid ratio suggests that soils under beech forests have a higher humification degree. The study highlights the influence of vegetation on SOC composition and the importance of conserving natural vegetation for soil health and carbon sequestration.
Contrasting impacts of heavy rainfall in neighbouring catchments: the 2nd September 2022 event in the western part of the Karlovo graben
Authors: Gerdjikov Ianko , Dotseva Zornitsa , Vangelov Dian
Published: December 2024

Post-flood field studies along the northern slope of the Sredna Gora Mountain indicate a drastically uneven response of the river channels to the extreme rain. Northwest of the village of Slatina four streams merge to join the Stryama River floodplain. The largest drainage basin is the westernmost one (0.3 km2), the other two are smaller (0.16–0.12 km2). Because these basins are adjacent, it is highly unlikely that during rainstorms, they will receive different amounts of precipitation. However, a six-hour extreme rainfall event generated significantly different impacts across the four catchments. Contrary to expectations, smaller watersheds were most severely affected, and channel changes were catastrophic. In contrast, the largest one was almost unaffected, with no evidence of transportation of significant amounts of clasts, as only vegetation stripping was observed in the vicinity of the channel. Field data, combined with analysis of post-event aerial imagery, indicate that the variability of the geomorphological response was conditioned by the occurrence of shallow landslides, which in turn transformed into debris flows.

Numerical models for the assessment of possible groundwater contamination during the utilization of waste from the mining and processing industry
Authors: Antonov Dimitar , Stoyanov Nikolay
Published: December 2024

A specific type of landfill, a tailings dam (or pond), is typically an earth-fill embankment dam used to store the byproducts of mining operations after the ore has been separated from the gangue. The primary threat posed by a tailings pond is the potential for leachate generated by the slurry to penetrate the soil and contaminate the aquifer. Based on the results of 1D and 3D model studies, a long-term forecast was made for the possible impact or contamination with arsenic and sulfate ions of the groundwater and surface water from the tailings pond and the contact pond under the extreme hypothesis that some of the engineering barriers do not fulfill their protective functions. On this basis, the general conclusion on the risk of water and soil pollution during operation and after the closure of the two facilities was formulated.
An example of the influence of fault tectonics on the engineering geological and hydrogeological conditions in the city of Sofia
Authors: Frangov Stefan
Published: December 2024

Sediments in the Sofia region (Bulgaria) characterize by rapid facies variability in horizontal and vertical directions. This is mainly due to the movements of the bedrock blocks during their formation. These motions have continued thereafter, resulting in the rupture and displacement of the strata. At present, similar outcrops are exposed at the bottom of large excavations. The uplifted and sunken flanks are composed of soils with contrasting mechanical properties and deformation behaviour. Additionally, the fault tectonics is observed to have a significant influence on the groundwater flow. The paper presents the findings on the differences between the engineering geological conditions established at the initial site investigation for a high-rise building and the unexpected strata revealed after the excavation was completed. When such difficulties are detected, further studies and actions are required to prevent uneven settlement of the foundations, stressing, deformation and cracking of the building structure.

Published: December 2024

Introduction. Osteoporosis remains a major public health issue, particularly affecting the elderly, and is characterized by decreased bone mass and deterioration of bone structure, increasing the risk of severe fractures. The development of specific and precise tools that allow for the identification and estimation of the influence of modifiable factors on the development of osteoporosis is an important step in early intervention for at-risk individuals. Material and methods. The initial version of the questionnaire was created to identify modifiable factors contributing to the development of osteoporosis, including the type and frequency of drinking water consumption, water quality, knowledge about its mineral composition, dietary preferences, alcohol and tobacco use, physical activities, and stressful situations. The questionnaire initially contained 65 questions, organized into three sections. Five experts reviewed the content validity, evaluating the clarity, cultural and linguistic relevance, structure, and coherence of the questions. The feedback led to adjustments, reducing the questionnaire to 52 questions. A pre-test was conducted with 30 adults from the Republic of Moldova, confirming the validity and internal consistency of the questionnaire, with a Cronbach’s Alpha coefficient of 0.768. Results. To ensure content validity, experts evaluated the questionnaire, and based on their comments and suggestions, semantic and syntactic reformulations and modifications were made. As a result, 13 questions were eliminated, reducing the second version of the questionnaire to 52 questions. During the pre-testing stage, the order and content of the questions were deemed appropriate by the respondents. The average time required to complete the questionnaire was 14.19 minutes (SD ± 1.567), with a minimum of 11.90 minutes and a maximum of 17.33 minutes. The sample used in the pre-testing stage included 30 respondents, the majority of whom (93.3%) were women. The respondents’ ages ranged from 25 to 72 years, with a mean age of 50.37 ± 2.6 years. The distribution of respondents was balanced between urban (53.3%) and rural (46.7%) areas. Regarding education level, 56.6% had higher education, 26.7% had secondary vocational education, and 16.7% had no higher education. Conclusions. The study demonstrated that the new questionnaire is a valid and reliable instrument for assessing the impact of modifiable risk factors on morbidity due to osteoporosis. Ongoing research is necessary to refine and further validate the questionnaire within the broader population.

Published: December 2024

Introduction. Disability-adjusted life years (DALY) is a multidimensional measure used to quantify specific tasks of the disease. Chronic liver disease attributed to hepatitis Delta virus (HDV) is one of the major causes that contribute to morbidity and mortality in our country. The DALY estimate in HDV-induced liver disease has the potential to highlight both fatal and nonfatal outcomes of the disease and thus, help in policy making and allocation of health resources. Material and methods. This was an analytical prognostic study conducted in the 2021–2024 period, with the enrollment of 104 patients with HDV-induced liver disease. YLL was predictively rated using Child-Pugh’s estimate of the remaining years of life. The chronic liver disease questionnaire was used to evaluate patients’ disabilities along with the disability weights of the Global Burden of Disease study, calculating YLD. The impact of DALY was interpreted according to the patient’s safety indicators. Results. 104 patients with HDV, originating in different areas of the country, were evaluated, with an average age of 56 ±4.5 years. Substantial YLD losses caused by HDV were mainly reported in working class. The greatest losses of YLD and DALY were caused by cirrhosis of the liver, followed by hepatocellular carcinoma. A great rate of mortality attributed to HDV was seen in the 45-59 and 60-74 age group. A total of 739.1 YLL in male gender and 719.5 in females were recorded for cirrhosis. Overall, men attest a DALY value of 1358.44 total/29.53 per person, and women registered – 1477.3total /25.47 per person. Conclusions. Chronic liver disease attributed to HDV is a medical challenge in Republic of Moldova. Loading the national medical system with serious and overwhelmed patients, make the DALY calculation approach a priority setting.

Authors: Colak Ilknur , Karadayı Gökçe
Published: December 2024

As a result of natural phenomena and anthropogenic activities, cadmium (Cd) accumulation in the soil has been increasing in recent years, and plants are directly exposed to this heavy metal, which is not essential for their life. In our study, UGT-3 (UDP-Glycosyltransferase-3), LTP-4 (Lipid Transfer Protein-4), Plasma Membrane PIP-1 (Plasma Membrane Protein-1) genes were investigated in Triticum aestivum L. plants exposed to Cd stress. It was aimed to determine the changes in expression levels in these genes and their methylation percentages for the first time using Real-Time PCR-based quantitative DNA methylation analysis (qAMP). In this context, DNA and RNA were isolated from the roots and stems of wheat grown by exposure to control, 100, 250 and 500 µM CdCl2 doses. Then, gene expression levels were determined by gene expression analysis with cDNAs obtained from RNA samples. DNA methylation percentages were determined by applying the qAMP technique. As a result, it was observed that the highest methylation percentage in the UGT-3, LTP-4 and PIP-1 genes was at 250 µM concentration in both the stem and the root. While the expression level of the UGT-3 gene was highest at a concentration of 250 µM in the stem, overexpression of the LTP-4 gene was observed at a concentration of 250 µM in the root changes in the methylation rates of UGT-3, LTP-4 and PIP-1 genes were investigated for the first time with qAMP, a new technique used in plants. A significant relationship was found out between the expression levels and methylation status of genes

Authors: Süleyman Selim , Şendur Yeşim , Tınar Yaşar
Published: December 2024

Extensive research has been conducted on the factors that influence a company's investment decisions. Both country-specific and firm-specific factors, impacting firms' investment choices, have been identified by researchers. Firm-specific factors encompass profitability, size, operating risk, liquidity, and growth potential. On the other hand, country-specific factors are delineated as economic growth, inflation, political and economic uncertainty, taxation, and legal regulations within the country. Literature studies suggest that, in addition to political and economic uncertainties, geopolitical risks also exert a significant influence on firms' investment decisions. The research below focuses on how geopolitical risks (GPR) affect the investing choices of 309 non-financial businesses included in the Istanbul Stock Exchange of Turkey. Data spanning ten years, from 2010 to 2019, was collected, and the unbalanced panel data method was employed for analysis. In light of the study's conclusions, an increase in Turkey's GPR Index corresponded to a decline in firm investments, aligning with expectations.

Informacinių technologijų skvarba pasiekė tokį lygį, kad be jų neįsivaizduojamas kasdienis daugumos žmonių gyvenimas, ir tai keičia tradicinį mąstymą tiek apie pasaulį, tiek apie žmonių bendravimą jame, tiek apie žmogaus savastį, tapatybę. Straipsnyje aptariama asmens tapatybės sampratos kaita tinklaveikos visuomenėje. Internetas sukuria naujo tipo komunikacijos erdves, kuriose žmonės gali naujai kurti ir įtvirtinti savo tapatybes, bendraudami vieni su kitais. Bendravimo tinkle savitumas turi reikšmingų pasekmių asmens tapatybės kūrybai. Įtinklintas bendravimas yra daug lankstesnis: komunikacijos kontekstas yra kuriamas pačių komunikacijos dalyvių, tad žmogus turi žymiai didesnes galimybes norimai save pateikti, modeliuoti tam tikrą savo tapatybę. Žinoma, virtuali aplinka nėra homogeniška anonimiškumo požiūriu, ir tai gali turėti įtakos asmeninės tapatybės kūrybos laisvei. Darbe nagrinėta tapatybės kaip nuolatinio vertybinio įprasminimo konceptualizacija leidžia suderinti dvi prieštaringas teorijas: ilgą laiką gyvavusią vienalytės asmens tapatybės sampratą, kurios socialinėje teorijoje linkstama atsisakyti kaip nebeatitinkančios šiuolaikinės dinamiškos visuomenės realijų, ir įsivyraujančią daugybinės, fragmentuotos tapatybės sampratą, kuri tapatybę pernelyg glaudžiai susieja su konkrečiomis tarpasmeninės sąveikos situacijomis ir todėl susiduria su iššūkiais bandant paaiškinti, kokiu būdu šios tapatybės sugyvena tarpusavyje viename asmenyje ir viename kūne.
Įtinklintas vaizdų gyvenimas: intensyvus žvilgsnis, asmenybės žavesys ir tapatybės (trans)formacija

Straipsnyje aptariama ambivalentišką dabarties vaizdų kultūra ir vizualumo bei matomumo galios. Vaizdo industrializacija ir komunikacijos technologijų plėtra suteikia prieigą prie vaizdų, demokratizuoja patirtį ir stiprina pretenzijas į beribį matomumą. Taip sudaro palankias sąlygas globalaus vizualumo – standartinių struktūrų ir kodų, sklaidai. Augantis publikos noras ir poreikis žiūrėti, stebėti kitus ir eksponuoti save plečia vaizdų industrijos karalystę, ją mistifikuojant ir padedant manipuliuoti kolektyvine sąmone. Todėl straipsnyje atidžiau tyrinėjamos vizualumo struktūros: kaip jos apibrėžia regėjimo horizontus, kaip stiprina autoritetą, simbolines ir finansines galias, kaip įtvirtina tam tikrus matymo ir suvokimo būdus, kaip sukuria herojus ir žvaigždes, kurie pritraukia publikos dėmesį, kaip individas atsiduoda stebėjimų ir susitapatinimų žaismei. Tyrinėjama vaizdinija ir praktika, primetanti savo valią socialinei ir kultūros sąrangai. Aptariama socialinė vaizdo galia – vaizdų įsitraukimas į visuomeninį gyvenimą. Analizuojamas iš kino industrijos kilęs žvaigždžių kultas, kuris matomumą paverčia kapitalo forma. Regimasis kapitalas nustelbia simbolinio ir kultūrinio kapitalo galias. Tai lemia radikalius pokyčius įvairiuose socialinio, kultūrinio ir politinio gyvenimo laukuose. Žvaigždžių kultas sukuria įvaizdžius ir suformuoja naujojo elito sampratą. Socialiniai tinklai lemia tolesnes spektaklio visuomenės transformacijas. Įsigali neperregimos tikrovės vaizdas, kupinas estetizmo, emocijų ir žaismės, noro pasirodyti, nukonkuruoti, laimėti.

Published: December 2024

This paper examines the impacts of certain food waste reduction measures and their effects on the population’s health. The research explores the performance of prevention measures like food donation and charity, education initiatives, and political decisions about fresh, healthy food provisioning and the incidence rate of food-borne illnesses. We also analysed these strategies’ statistical significance and effectiveness by employing Principal Component Analysis (PCA), Chi-square tests, Linear Regression, and ANOVA, using data collected from recent studies. When comparing the PCA results to the devised framework, food redistribution programmes and food access improvements were recognised as major factors for 68% of the variation in the effects of reduced food waste. A chi-square comparison showed a strong correlation between the level of food redistribution and a 15% decrease in food illnesses (p < 0.05). Linear regression revealed that due to educational programmes, the percentage of people with access to healthy foods increased by 34% p <0.001). Analysing the effectiveness of the actions realised within the framework of the presented project, such as educational programmes, the increase in the percentage of people with access to healthy foods was received by 34% ( p < 0.001). Specific distinctions in general and normalised population health parameters depending on the type. The lack of supply-side policies was identified as evidence proving that multi-level interventions are vital for reducing food waste and improving public health.
existencia de intermediarios ocultos en el traslado de mercancías y sus repercusiones para el Comercio Exterior
Authors: López Luna José Emmanuel , Moreno Villa Alejandro , Herrera Luna Karla Aylin , León Arredondo Edson Alexandr
Published: December 2024

El objetivo del artículo es dimensionar las implicaciones de la existencia de intermediarios ocultos en el traslado de mercancías de comercio exterior; se fundamenta en la teoría de la tercerización. A través de una encuesta aplicada a las 35 empresas transportistas de Manzanillo se obtuvo la información que da sustento a la investigación. La existencia de intermediarios ocultos es una realidad que no se puede negar, y si bien podría implicar el encarecimiento del servicio de autotransporte, es un sobrecosto que el mercado en general puede absorber. Eventualmente todos los implicados en operaciones con intermediarios ocultos obtienen un beneficio: el importador consigue el transporte necesario para su mercancía, el auto transportista de primer contacto y el intermediario oculto obtienen ingresos.
Seesawing (dis)connections: Digital parent involvement in a culturally diverse school community
Authors: Nichols Sue , Dooley Karen , Soong Hannah
Published: December 2024

As digitisation of home-school connectivity continues apace, nuanced understandings of the digital capabilities of parents are essential. Yet, there has been considerable homogeneity in the representations of parents, and deficit understandings of digital parental involvement with schools, especially in schools serving diverse and disadvantaged communities. The study reported here addressed these limitations of the extant research by asking how families in a case study school oriented to digital technology, how cultural and linguistic resources impacted home-school connections, and how a learning management system impacted digital inclusion in a diverse school community. Parent interviews were facilitated by interpreters, enabling participation of a culturally and linguistically diverse parent cohort.  Parents’ and teachers’ diverse perspectives were analysed. Informed by Actor Network theory, connections between humans and humans, and between humans and hon-human actors (digital and material), were mapped onto a network diagram. Findings show considerable digital engagement and aspiration on the part of parents, which was frustrated by English-only communications from teachers despite Seesaw’s multilingual affordances. We report teachers’ disappointment with low parental uptake of the digital learning management system, and the deficit thinking which led them to assume a lack of digital skills or knowledge. We suggest that such deficit thinking should be challenged by a critical approach which might involve teacher-parent dialogue. Although a learning management system is a technological actor, that actor must be understood within the full context of school-home connectivity, in which schools serve communities and have a responsibility for cultural and linguistic inclusion.
Using Queen Sugar as a Lens to Counter Hegemonic Conceptions of Black Fathers’ Involvement in P-12 Schools
Authors: Hooper Leta , Muzeta Brenda
Published: December 2024

The depictions of Black fathers and their relationships with their children on television sitcoms influence societal perceptions of Black fathers’ parenting practices, Black families’ configurations, and public policies on Black families. This paper sheds light on how excerpts of the show, Queen Sugar challenge narratives and images regarding Black fathers’ relationships with their children, particularly their Black sons. Revolutionary parenting and critical race media literacy are used as theoretical concepts to examine the interactions and experiences between Ralph Angel and Blue. Content analysis was employed to generate findings that examine the bond between Ralph Angel and Blue, Ralph Angel’s support for Blue’s toy choice, and his engagement in Blue’s education. Implications of this work illustrate how experiential learning activities, metacognitive activities, and popular culture sources that consider Black parents' voices and experiences with child-rearing and schools be used as an analytical and pedagogical tool in teacher education courses to counter deficit ideologies that aim to stereotype and marginalize Black parents in education settings.
