Assembling Reading and Writing in the Face of Loss: Christa Couture’s How to Lose Everything and Dakshana Bascaramurty’s This Is Not the End of Me
Authors: Artacho-Martín Lola
Published: January 2025

Through nonfictional texts dealing with complicated and traumatic experiences related to loss, readers and writers seem to become more intricately entangled. Following Rita Felski, reading is said to ignite a process of “recognition” (23) which might be paralleled to the self-discovery process which writing may achieve. Sympathy and mutual identification arise and bring readers’ and writers’ identities closer, creating an intersubjective space where health and illness assemble their relations. This analysis of Christa Couture’s How to Lose Everything and Dakshana Bascaramurty’s This is Not the End of Me: Lessons on Living from a Dying Man will attempt to show that there is a tight link between reader and writer through nonfiction which transcends the literary text. In addition, the healing nature of this connection will be highlighted, which supports the idea of using reading and writing techniques as therapeutical strategies in the coping with emotional turmoil and distress.
Kiskisitotaso, Don’t Forget Yourself: Indigenous Resurgence in David A. Robertson’s Barren Grounds
Authors: Samuelson Anah-Jayne
Published: January 2025

David A. Robertson’s (Norway House Cree) children’s novel The Barren Grounds (2020) intervenes in Canada’s historical and ongoing child welfare systems’ impacts on Indigenous children and youth. This article argues that Indigenous children’s literature could significantly contribute to the ongoing efforts towards reconciliation in Canada. Robertson, as a specific example of this, presents a decolonized version of foster care that is rooted in Indigenous resurgence and grounded normativity. This representation encourages young readers to reconsider entrenched settler-colonial structures that, potentially, advance the projects of reconciliation and decolonization in Canada. Barren Grounds considers alternatives to current foster care structures that are predicated on Indigenous foster children and youth being directly reconnected with Indigenous peoples, lands, and knowledge systems. This reconnection transmits grounded normative ethics and builds Indigenous resurgence—both of which Robertson demonstrates are key in combating settler-induced disconnection and dispossession.
Plastic Production and Trade in Small States and SIDS: The Shift Towards a Circular Economy
Authors: Barrowclough Diana , Vivas Eugui David
Published: January 2025

This paper focuses not only on the special needs of small states and small island developing states (SIDS) in the challenge to reduce plastics pollution, production and trade, but also on the opportunities. It draws on new information made available in an UNCTAD prototype database that tracks trade in plastics across the entire life cycle and identifies phases in the plastics industry that could offer export opportunities to small states and SIDS. However, this kind of structural transformation will not happen by itself. Part of the solution will depend upon having coherent trade policies, industrial circularity, effective waste management policies and incentives for the emergence of sustainable plastic substitutes and related sunrise industries that meet the need to reduce plastics use and pollution.
Natural Disasters and Recovery Efforts: Tapping into Trade Facilitation as a Response Tool
Authors: Wilkinson Andrea , Stevens Beatriz
Published: January 2025

This issue of Trade Hot Topics explores the linkages between trade facilitation and natural disasters, highlighting key provisions of the World Trade Organization (WTO) Trade Facilitation Agreement (TFA) and exploring novel issues in trade facilitation to shed light on this interplay to better understand how countries can promote trade facilitation reform with a view to responding better to the impacts of natural disasters.

The Commonwealth Secretariat’s Countering Violent Extremism (CVE) Unit has always emphasised the importance of young people and youth mainstreaming within the work that we do.

The CVE Unit organised ‘The Power of Youth to Build Peace in the Commonwealth’ in collaboration with CYPAN, in order to give young Commonwealth citizens that meaningful seat at the table. Taking place in November 2020, the event was a sub-session of the Commonwealth Action Series, organised by the Commonwealth Youth Programme.

In lieu of a physical Commonwealth Heads of Government Meeting (CHOGM) and Commonwealth Youth Forum (CYF) event taking place in 2020, the Commonwealth Youth Programme organised a series of virtual events that focused on the themes
selected for the 2020 CHOGM.

The panellists were chosen by the CVE Unit from the Specialist Pool and from CYPAN, and each produced a policy paper relevant to the overarching theme of the workshop but within their areas of expertise.

These fascinating, insightful and varied policy papers are published in this first edition of the Preventing and Countering Violent Extremism Discussion Paper series.
Evaluating the Efficacy of Diverse Machine Learning Techniques in Disease Detection: A Comparative Analysis
Authors: Guang Zhi
Published: January 2025

Detecti​ng diseases early is very important to help patients get results and lower healthcare expenses​s​. The field of machine learning has become highly valuable, in the healthcare industry as it can improve precision and effectiveness. In this research study​ we are examining how machine learning methods such, as Support Vector Machines (SVM) Random Forest (RF) Convolutional Neural Networks (CNN) Long Short Term Memory (LTSM) and Gradient Boosted Machines (GBMs) perform in detecting diseases. Information was gathered from Google Scholar regarding studies that utilized these models in the context of illnesses like diabetes and cardiovascular diseases well, as cancer and infectious diseases. The models were evaluated by considering their accuracy levels along with sensitivity and specificity measures in addition, to AUC‐ROC values. The findings reveal that Convolutional Neural Networks (CNN) achieved the level of accuracy at 99·54% along, with an AUC–ROC score of 99· RF models also showed strong performance with an accuracy of 96·74% and an AUC–ROC score of 99· showcasing their ability to handle extensive datasets effectively· Gradient Boosted Machines (GBMs) demonstrated high accuracy at 97·57% as well as a notable AUC–ROC score of 98· proving their effectiveness in predicting diabetes mellitus· Support Vector Machines (SVM) and Long Short Term Memory networks (LSTM) delivered reliable results as well; particularly noteworthy was the utility of LSTMs, in modeling temporal sequences for chronic disease monitoring purposes· The research points out the pros and cons of machine learning methods. Offers valuable information, on how they can be used in real life medical scenarios effectively. It indicates that incorporating ML models into the healthcare sector has the potential to boost detection of diseases and enhance treatment while also cutting down on medical expenses. Future studies should concentrate on broadening data sources to include a range of populations and establishing standardized assessment criteria to improve the reliability and practicality of ML models, in disease detection.
Bruce Springsteen
Authors: Streight Irwin H.
Published: January 2025

This chapter examines the songs and sensibilities of rock icon Bruce Springsteen, who has acknowledged O’Connor’s arc of influence on his artistic vision and practice from songs The River (1980) and Nebraska (1982), his autobiography Born to Run (2016), and through to the Netflix offering of his initial Springsteen onBroadway stage run (Oct. 2017-Dec. 2018). Springsteen’s Catholic upbringing imprinted in him what he calls an “internal landscape,” and his songs, like O’Connor’s stories and novels, are grounded in the concept of Original Sin and the redemptive themes of their shared Catholic outlook. Springsteen acknowledges that O’Connor’s idea of an underlying “meanness” in the human heart and her violent literary means through which religious mystery is encountered have had a shaping influence on his darkly redemptive song stories. He states in an interview that his songwriting was transformed through reading her stories, a shift to more narrative-style songs with small, telling details that reveal character in ways that mirror the art of the short story.
On the Perils of Enjoying One’s Wound
Authors: Murray Derek Conrad
Published: January 2025

From visual art, to literature, to film, and in many respects within academia, Black pain is chic and sexy. This visual regime is not only driven by the interests and demands of the so-called dominant culture, but is also an often-unspoken mandate of the Black intelligentsia, frequently intended as a form of recuperation and celebration, even as a polemical means to compel society to acknowledge its historical and present-day sins. But what happens when Blackness becomes sutured to pain and deprivation? What are the consequences if Black representational presence becomes overdetermined as struggle? This essay considers whether the brand of satire found in the television serials Atlanta and Them and in Radha Blank’s film The Forty-Year-Old Version ultimately transcends or reinforces the fetishization of Black suffering.
Awkwardness and Black Millennial Satire in Insecure and Atlanta
Authors: Horhn Erica-Brittany , Maus Derek C.
Published: January 2025

Generational categorization is a longstanding critical practice with considerable utility in tracing out significant developments in Black artistic expression. The recent emergence of Black satirical artists belonging to the so-called “Millennial” generation necessitates reconsideration of the traits and tendencies that differentiate this new cohort while still connecting them to earlier comic-satiric traditions. The extent to which their satirical sensibility is pervaded by a sense of awkwardness exemplifies this duality, recalling and transforming work by a range of Black and non-Black ancestors. The roughly contemporaneous television serials Atlanta and Insecure signal an intergenerational “passing of the baton,” that attests to the artistic maturation of two Black satirists – Issa Rae and Donald Glover – too young to be firmly among the much-theorized “post-soul” generation theorized by Mark Anthony Neal and others but also old enough to have experienced the racialized highs and lows of the Obama and Trump presidencies as adults.
“What the Hell Is Muckin’?”
Authors: Boorman Lola
Published: January 2025

From the opening scene of the pilot episode, Atlanta refuses to orient its linguistic worldview around a process of code-switching between Black and white vernaculars, between “non-standard” and “standard” forms of English. Although such strategic fluctuation has features prominently in contemporary Black satirical works, Atlanta pointedly resists this familiar opposition. Its satire emerges instead from repeated instances of linguistic misunderstanding and mistranslation from within its enclosed “community.” Throughout Atlanta’s four seasons we see characters repeatedly collapse into miscommunication as they try to translate their experiences and desires into various socially legible discourses. This essay explores how Atlanta’s complex dynamic of linguistic inclusion and exclusion plays out; incidences of linguistic misunderstanding manifest predominantly as various forms of dispossession, although some characters echo such precursors as Fran Ross’s novel Oreo in using linguistic instability and untranslatability as productive openings for self-expression, thereby becoming a means of interrogating the show’s representations of masculinity.
Playing on the Border
Authors: Lee Abigail Jinju
Published: January 2025

This essay considers how representations of racial ambiguity and racial passing in Atlanta and in Charles Yu’s novel Interior Chinatown are deployed to expose the messy, impossible edges of supposedly unequivocal racial categorizations. It begins by tracing a lineage of satire that challenges racial borders in both African American and Asian American literature and performance. Next, it argues that Atlanta’s satire of racial boundaries articulates Blackness as a radical break from normative, unmarked whiteness – a way of being otherwise. Finally, it unravels the borders separating Asianness, Blackness, and the racially ambiguous in Interior Chinatown to explore the novel’s ambivalent construction of Asianness; it sympathetically upholding a dream that Asian Americanness could become normatized while also still satirizing the stereotypes that constrain Asianness. Through these satirical lenses, racialization becomes apparent as a dynamic, multivalent process of exerting power and violence that necessarily conceptualizes racialized groups in relationship to each other.
Life in the Permanent War
Authors: Yamane Ryoichi
Published: January 2025

This chapter explores the presence of nuclear imagery in and around the writings of Faulkner, Welty, and Wright. The March 5, 1956, issue of Life magazine featured Faulkner’s essay on racial integration, a review of the theatrical adaptation of Welty’s The Ponder Heart (1954), and an article that highlighted the aspirations of Russian and Chinese engineers and students to rival the United States in the nuclear arms race. Wright’s anti-neocolonialist perspective in The Outsider (1953) develop this combination of racism and militarism and contrast between the US South and the USSR, illustrating its protagonist’s pursuit of freedom that leads to attacks on racial and ideological others. In light of Joseph Darda’s analysis of the US perpetual war, where racism and militarism were seen to have a reciprocal relationship, this chapter ultimately suggests the importance of reexamining the nuclear imagination embedded or possibly repressed within the US southern cultural fabric.
The Transit of Memory
Authors: Faulkner William , Ward Jesmyn , Welty Eudora , Ford Sarah Gilbreath
Published: January 2025

This chapter examines how Jesmyn Ward both borrows from and speaks back to William Faulkner and Eudora Welty by employing the idea of mutual hauntings. Texts written by Faulkner and Welty haunt Ward’s Sing, Unburied, Sing, as Ward borrows from these earlier writers a gothic sense of the fluidity of time. All three writers link the erasure of the boundaries between the past and the present with physical movement through space. This attention to movement produces ghosts not bound to places they want to control but focused instead on claiming ownership of narratives, specifically their own stories of oppression and loss. Ward’s novel haunts Faulkner’s and Welty’s works in turn by enlarging the aperture of haunting to amplify the larger racial dimensions of memory and narrative.
“Why Am I Treated So Bad?” … “Compared to What?”
Authors: Smith Mike
Published: January 2025

Jazz musicians were some of the most highly recognized Black Americans, and their role in helping to make change is very important to the story of civil rights. In the instrumentation, in the performance practices, and in the song lyrics, it became obvious – the music that they created to protest and express their feelings changed and adapted to the urgency of the 60s. This new militancy became very direct, and to a large degree, this was the major factor for the change in the sound of jazz by the end of the decade.
Seasons At Lakeside Dairy
Authors: LeFalle-Collins Lizzetta
Published: January 2025

This chapter details how Angus Bates ran Lakeside Milk Dairy in Shreveport, where he managed a successful dairy business, producing Grade A milk, cream cheese, and sour cream. His hard work and self-education enabled him to build a large two-story home on Talbot Street for his family. Despite initial skepticism, Angus's perseverance paid off, and his dairy business flourished. By the time of his death in 1935, Lakeside Dairy had grown substantially and played a crucial role during the 1925 fire that threatened the Allendale community, with the Bates family successfully saving their home and farm. Angus's innovative farming practices, inspired by Booker T. Washington and George Washington Carver, contributed to the farm's sustainability. The Bates family also overcame racial barriers and supported local Black entrepreneurship, serving primarily immigrant communities due to racial segregation. The family was actively involved in both agricultural and household tasks, including planting vegetables, managing livestock, and handling pollution challenges. Grandma Bates ran a cottage enterprise and kept meticulous records while the family maintained their traditions through seasonal celebrations. The chapter considers the shared histories of resilience and adaptation of the Bates and Leffall families, and how their story reflects the significance of family recipes and culinary heritage in maintaining traditions and contributing to their community.
Working Through The Icy Winter Days and Nights
Authors: LeFalle-Collins Lizzetta
Published: January 2025

This chapter describes how the Louisiana landscape was often muddy and rainy, causing children to navigate through mud on their way to and from school. At home, they would remove their dirty shoes and line them up on the porch to keep the house clean. Winter chores included feeding cows, delivering milk, and making biscuits, while children stayed indoors during severe cold. The author's family adapted to the cold by using a fireplace for warmth and cracking nuts for sustenance. They utilized peanuts, inspired by Dr. Carver's agricultural advice, as a key winter food source. Meanwhile, Grandma Bates prepared for quilting by collecting colorful fabric scraps, inspired by Dr. Carver's work with natural dyes. Quilting was akin to seasoning, reflecting Carver's belief in the harmony between colors in art and food. The family also preserved fall vegetables for winter soups, enjoyed sweet potatoes cooked in the fireplace, and occasionally added wild game to their meals. Winter was a time for indoor activities, including sewing and storytelling, while younger family members engaged in outdoor fun like rabbit hunting. The chapter concludes with recipes for a sweet potato and apple dish and Christmas nut cake, highlighting family traditions and seasonal cooking.
Martin Luther King Jr.’s American Legacy
Authors: Brown Owen
Published: January 2025

This chapter draws a parallel between Martin Luther's revolutionary challenge to the corrupt practices of the Roman Catholic Church and Dr. Martin Luther King Jr.'s struggle against racial inequality in the United States. Dr. King's legacy, marked by his pivotal role in the Civil Rights Movement and the dismantling of Jim Crow laws, remains vital as many of the injustices he fought against persist in “postracial” America. The chapter uses Fernand Braudel's concept of the longue durée to situate Dr. King's impact within the broader historical context of African American experiences. It also illustrates how historical injustices continue to shape present-day struggles. By linking Dr. King's legacy to contemporary movements like Black Lives Matter, the chapter underscores the enduring relevance of his fight for racial and social justice.
Blackness as Spectral Presence Postracial Discourses in Fresh Off the Boat
Authors: Davis Patricia G.
Published: January 2025

This chapter cites the show Fresh Off the Boat as a critical example of how racial poaching operates within postracial discourses in contemporary popular culture. By focusing on an Asian American family while co-opting aspects of Black culture, the show reinforces dominant values and perpetuates marginalization. It describes the sitcom's portrayal of Eddie Huang's character, which exemplifies the use of cultural appropriation by one minority group to gain proximity to whiteness. It also highlights how postracial fantasies obscure ongoing anti-Blackness by making racial differences appear less threatening to a white audience. The chapter argues that Fresh Off the Boat both advances and conceals the ideologies that sustain racial hierarchies, ultimately maintaining the invisibility and displacement of Blackness in popular culture.
Excavating the Ruins of Tulsa’s Greenwood District
Authors: Craig Byron B , Rahko Stephen E. , Jordan J. Scott
Published: January 2025

This chapter highlights HBO's series Lovecraft Country as a cultural response to the postracial discourse exemplified by the phrase All Lives Matter, particularly in the context of the Tulsa Race Massacre of 1921. It details the series' depiction of the massacre as a counter-narrative to the rhetoric that seeks to minimize race-specific traumas and injustices, such as those indicated by the Black Lives Matter movement. By dramatizing the cultural trauma of racialized violence, Lovecraft Country challenges the postracial claims that undermine the need for reparations and acknowledgment of systemic racism. The chapter argues that such portrayals disrupt America's postracial political condition by reasserting the significance of racial violence as a critical force in shaping public discourse and collective memory. It situates Lovecraft Country within broader debates on racial trauma, reparations, and the enduring impact of America's violent racial history.
Pittsburgh’s Postracial Hill District?
Authors: Sciullo Nick J.
Published: January 2025

This chapter focuses on the Hill District in Pittsburgh as a focal point of racial and spatial contestation, revealing how postracial discourse has shaped the redevelopment narrative of this Black community. While the City of Pittsburgh's official rhetoric aims to present the Hill as a natural and healthy community, it overlooks the complex realities of racialized histories that have defined the neighborhood. The chapter challenges the postracial narratives that obscure ongoing racial struggles. It includes Denzel Washington's adaptation of Fences and Steve Mellon's multimedia story “A Life on the Hill,” which offer a nuanced portrayal of the Hill. It also emphasizes that understanding the Hill District's history and the rhetoric surrounding its redevelopment is crucial to resisting the erasure of Blackness in urban spaces.
Proverbs Shaping Legacies
Authors: Summerville Raymond
Published: January 2025

The conclusion begins by exploring the need for additional scholarship about female civil rights leaders. While not all notable civil rights figures used proverbs often in their language, certain phrases nonetheless became significant to the movement, such as Ella Baker’s famous “bigger than a hamburger” phrase. Like Ella Baker, Julian Bond was also not especially known for his proverbial sayings but nonetheless was active in civil rights organizations for decades and highly valued proverbs such as the Golden Rule and “speaking truth to power.” The conclusion also discusses civil rights pioneer Gordon Parks. While no proverb master, Parks still possessed a mastery for metaphorical language and appreciated the rhetorical strength of Carmichael. In conclusion, the legacies of important people may be communicated through proverbs, expressions, or sayings even if these devices were not a widely recognized characteristic of the individual's communication style.
Exile and Instrumentality in the Emily Books
Authors: Hui Lim Jessica Wen
Published: January 2025

The chapter returns to one of the most cherished observations about the Emily books, namely their debt to Wordsworth, particularly through Emily’s flash. By way of a careful and personal re-examination of the subtlest nuances of Wordsworth’s “flash that has revealed/The invisible world,” Lim argues for a new understanding of Emily’s flash through a more precise understanding of Wordsworth. Lim demonstrates that an inevitable element of Emily’s Romantic insight is displacement, alienation from exactly the elements of companionship and belonging that she most desires, adding a new dimension to one of the most familiar ways of reading the trilogy.

Ecolinguistic Approach to Online Finnish Discourse on Invasive Alien Species
Authors: Uusitalo Harri , Suomalainen Karita
Published: January 2025

This ecolinguistic article investigates how alien species are perceived in mundane interactions in Finnish online discussions, based on data collected from the popular Finnish Suomi24 online discussion forum. We ask: What organisms does the lexical item vieraslaji ‘alien species’ cover for the forum participants, and what kinds of discourses are built around the term vieraslaji? The results of digital content analysis and discourse analysis show that nonhuman animals and humans are much more common topics than plants; this indicates that the nature discourse related to alien species is animal centered and that certain species dominate the discussions. The lexical item vieraslaji is used in affective contexts, reflecting the fact that discussion of invasive species is emotionally laden. Our analysis also reveals that the discursive features of online discussions on invasive species show similarities with online anti-immigration hate speech discourse, and that xenophobic discourse is partially inspired by the nature discourse. Based on these results, we argue that a more diverse discussion about alien species is needed.

Effect of Dolomite Lime on pH and H2S of Mangrove Acid Soil
Authors: Nugraha Bagas Aditya , Purnomo Pujiono Wahyu , Rahman Arif
Published: January 2025

Generally, the soil where mangroves grow is soil that has a low level of maturity. The soil around the mangrove forest is a source of pyrite (iron sulfide), so it has a low pH. Using lime will help increase the soil pH so that it is not too acidic. One of the materials used for liming is dolomite lime. The research objective was to determine changes in the concentration of pH, H2S, and nitrate on dolomite lime and to determine the effect of differences in concentrations between those with added dolomite and those not added. This research is experimental with dolomite treatment respectively 6 g, 12 g and 12 g. The variables measured were pH, H2S, and nitrate. The measurement time is for 9 days with an interval of every 3 days. The data analysis used was variance (ANOVA).The results of the ANOVA test showed that dolomite lime had an effect on pH and H2S (α <0.05) and had no effect on the nitrate variable (α> 0.05).
Investigating the antioxidant, anti-inflammatory and anti-cancer potential of Ononis natrix L. with phytochemical analyses
Authors: Ahmed M M Youssef , Noha E A Mohamed , Khaleel R Abuawad , Mohammad A ‎Alkhojah , Rasha M ‎Hussein
Published: January 2025

Ononis natrix L. (O. natrix) belongs to Fabaceae family and ?grows on the coast of Mediterranean Sea. The current study aims to investigate the antioxidant, anti-inflammatory and anti-cancer activities of the methanolic extract of O. natrix and identify the phytochemical constituents responsible for these effects. Gas chromatography-mass spectrometry (GC-MS) was employed to characterize the phytochemicals found in the extract. The human red blood cells (RBCs) membrane stabilization method, ferric reducing antioxidant power (FRAP), total antioxidant capacity (TAC), 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging assay and MTT viability assay were used to investigate the anti-inflammatory, antioxidant and anti-cancer activities. The results showed that methyl stearate (39.48%) and hexadecanoic acid, methyl ester (35.61%) were the most relatively abundant phytochemicals identified by GC-MS. The % hemolysis inhibition for RBC membrane achieved by O. natrix extract was 99.6 ± 1% versus that by indomethacin  was 99.9 ± 0.6%. Additionally, the DPPH radical scavenging activity of O. natrix extract versus ascorbic acid was 97 ± 0.3% and 98 ± 0.2%, respectively. The O. natrix extract showed a lower anti-cancer activity against DLD-1 cells (IC50 = 57.13±4.9 µg/mL), MCF-7 cells (IC50 = 96.69±6.2 µg/mL) and A549 cells (IC50 = 126.63±10.4 µg/mL), when compared with the anti-cancer drug; Cisplatin. Therefore, O. natrix extract showed significant anti-inflammatory, antioxidant and anti-cancer properties, which could be attributed to methyl stearate and hexadecanoic acid, methyl ester constituents.
Evaluation of the content of polyphenols, flavonoids, tannins, antioxidant capacity and antibacterial activity of Pelargonium graveolens flower extracts
Authors: Najlae El-otmani , Ikrame Zeouk , Hayat Ben-saghroune , Ahmed Zahidi
Published: January 2025

Pelargonium graveolens has garnered attention for its therapeutic properties, especially in treating dermatological conditions. The aim of this study was to investigate the phytochemicals, antioxidant action and antibacterial effect of its flower extracts obtained through maceration, sonication and infusion. The findings show that the highest total phenolic content was obtained from the hydroethanolic sonication extract (280.39 mg GAE/g), followed by the hydroethanolic maceration extracts (272.87 mg GAE/g). The total flavonoid content varied from 21.51 mg EQ/g (hydroethanolic maceration) to 12.32 mg EQ/g (aqueous infusion). Condensed tannins were highest in the hydroethanolic maceration extracts (8.40 mg/mL). Additionally, the antioxidant action was assessed using the DPPH, FRAP, TAC and ABTS methods. The extracts from hydroethanolic sonication showed a high free radical scavenging capacity (IC50 = 0.31 mg/mL) compared with extracts from aqueous infusion and hydroethanolic maceration. However, antibacterial tests revealed that all extracts had better activity against Gram-positive bacteria. The hydroethanolic maceration extracts showed pronounced sensitivity, exhibiting zones of inhibition ranging from 13 to 24 mm for Gram-negative bacteria and 19 to 24 mm for Gram-positive bacteria. These extracts demonstrated significant efficacy against methicillin-resistant Staphylococcus aureus and Panton-Valentine Leukocidin-Positive Staphylococcus aureus. These findings suggest potential applications in the pharmaceutical and dermatological fields, particularly for developing natural antioxidant and antibacterial agents.
Changes in the nutritional composition of corn silage w ith the use of chemical additives and microbial inoculants
Authors: Zanella Jaqueline Beatris , Rommel Alan Alberto , Turmina Amanda , Rosin Matheus Ramos , Silveira Magali Floriano , Cattelam Jonatas
Published: January 2025

This work aimed to evaluate the use of different additives in the bromatological composition of corn silage. The experimental design was completely randomized with five additives evaluated: no additive; silage added with urea (3.0%); silage added with limestone (3.0%); silage added with granulated sugar (3.0%); and silage with bacterial inoculant. After 60 days of ensiling, the chemical-bromatological composition of the produced silages was evaluated. Lime-added silage had higher dry matter contents (not differing from silage with no additive), mineral matter, and lignin. Silage with urea had higher values of crude protein (19.55%) and lower levels of total carbohydrates (74.29%) and non-fiber carbohydrates (27.13%). Silage with no additive had lower levels of ADF (38.99%) and NDF (19.79%) and a higher content of total digestible nutrients (73.98%). Using additives in corn silage promotes higher concentrations of acid or neutral detergent fiber, cellulose, and hemicellulose and lower TDN levels in its bromatological composition. The addition of urea provides an increase in protein levels, while limestone increases mineral material levels.

Foram diagnosticados 105.188 casos novos de tuberculose por todas as formas clínicas na Bahia e registrados 2.514 óbitos pela doença. O maior número de casos foi em 2003 e o menor em 2020, primeiro ano da COVID-19 no Brasil. O mesmo comportamento foi observado para a taxa de incidência. A maior proporção de casos novos de tuberculose foi observada em pacientes do sexo masculino, na faixa etária entre 20 e 39 anos, pardos, com ensino fundamental incompleto e apresentando a forma pulmonar da doença. Houve associação significativa entre a forma clínica da tuberculose com as variáveis sexo, síndrome da imunodeficiência adquirida, alcoolismo, tabagismo, drogas ilícitas e encerramento do caso. Observou-se que a pandemia pela COVID-19 reduziu o número de casos novos de tuberculose diagnosticados e aumentou a taxa de mortalidade em 2021 e 2022, revertendo os progressos no controle da doença conseguidos até então.
Anonymous job applications and hiring discrimination
Authors:   IZA, Rinne Ulf
Published: January 2025

The use of anonymous job applications (or blind recruitment) to combat hiring discrimination is gaining attention and interest. Results from field experiments and pilot projects in European countries (France, Germany, the Netherlands, Finland and Sweden are considered here), Canada, and Australia shed light on their potential to reduce some of the discriminatory barriers to hiring for minority and other disadvantaged groups. But although this approach can achieve its primary aims, there are also important cautions to consid

The monitoring and optimizing training load is a concept designed to decrease risk of injury while improving physical fitness and performance. This area has grown significantly in popularity, especially in the sporting world. However, these principles can be applied to other populations, such as tactical personnel who likewise are at increased risk of injury and engage in physically demanding occupational tasks that require sufficient fitness. Although monitoring the training load in tactical personnel may be effective, the critical differences between athletic and tactical populations necessitate occupationally specific load monitoring programs. This article aims to identify these barriers and suggests potential solutions for practitioners and researchers.
Modulatory neurotransmitter genotypes shape dynamic functional connectome reconfigurations

Dynamic reconfigurations of the functional connectome across different connectivity states are highly heritable, predictive of cognitive abilities, and linked to mental health. Despite their established heritability, the specific polymorphisms that shape connectome dynamics are largely unknown. Given the widespread regulatory impact of modulatory neurotransmitters on functional connectivity, we comprehensively investigated a large set of single nucleotide polymorphisms (SNPs) of their receptors, metabolic enzymes, and transporters in 674 healthy adult subjects (347 females) from the Human Connectome Project. Pre-registered modulatory neurotransmitter SNPs and dynamic connectome features entered a Stability Selection procedure with resampling. We found that specific subsets of these SNPs explain individual differences in temporal phenotypes of fMRI-derived connectome dynamics for which we previously established heritability. Specifically, noradrenergic polymorphisms explained Fractional Occupancy, i.e., the proportion of time spent in each connectome state, and cholinergic polymorphisms explained Transition Probability, i.e., the probability to transition between state pairs, respectively. This work identifies specific genetic effects on connectome dynamics via the regulatory impact of modulatory neurotransmitter systems. Our observations highlight the potential of dynamic connectome features as endophenotypes for neurotransmitter-focused precision psychiatry.

Significance StatementUnderstanding how genetic variations affect brain activity and connectivity can unlock new insights into cognitive abilities and mental health. This study reveals that specific genetic variations influence how long the brain stays in different connectivity states and how it transitions between these states. These genetic variations were found in two modulatory neurotransmitter systems: acetylcholine and noradrenaline. These findings suggest that brain connectivity patterns influenced by genetics could serve as markers for personalized psychiatric treatment, pushing the boundaries of precision psychiatry.
Propuesta de modelo de gestión para el absentismo universitario

This research accepts the definition of university absenteeism as the conscious andpremeditated action of being absent from the physical environment of the universityclass”(Rojo Gallego-Burin, 2016, p. 87). From the figures of the IntersemesterAbsence Rate (TAI) we can affirm that the phenomenon of absenteeism is currentlyof great importance due to the fact that it has been increasing annually, becomingone of the university problems that affects professional, personal and academiclife. student’s academic performance that can lead to a serious consequence suchas dropping out. A measurement model for this phenomenon is proposed usingthe European Foundation for Quality Management (EFQM) Model. For the NationalAccreditation Council (CNA), through Agreement 02 of 2020, permanenceand graduation stand out as a fundamental part, having institutional and nationalpolicies as a reference, providing accompaniment on a semi-annual basis. Wherea characterization of the students is carried out at the time of admission in orderto monitor their training process. The MEN, based on Resolution 021795 of2020, proposes the description of the pedagogical models that lead to learningresults, giving added value to its fundamental part, students and teachers withcomprehensive leadership, executing through strategic alliances the strengtheningof permanence and graduation. Based on the proposed measurement model, it contributesto achieving one of the objectives of Agreement 014 of 2021 of the UPTCpermanence and graduation policy, establishing the foundations to generate anUpetecist permanence and graduation management model that responds to themulticausal nature and dynamics of desertion, thus achieving the strengthening ofacademic, personal and human aspects of students.
The Effect of Duolingo on l2 Learners’ Pronunciation: Vowel Analysis through Minimal Pairs
Authors: Balčytytė Giedrė , Skerstonaitė Viktorija
Published: January 2025

The present paper focuses on the acoustic analysis of Russian speakers’ English vowel production before and after using the Duolingo application. The study aims to investigate phonetic acquisition of English vowels, particularly in the context of minimal pairs. The method chosen to achieve this objective is experimental analysis using phonetic acoustic variables – formant frequencies (F1 and F2) and vowel duration which were evaluated through spectrograms. Ten Russian-speaking volunteers participated in the experiment and were treated pre-test and post-tests. The results observed in this experiment show that Duolingo application contributed to Russian speakers’ production of tense/lax English vowel pairs /u/-/ʊ/ and /i/-/ɪ/ with F1 and F2 frequency values closer to those of British English, but no improvements were seen with the open front vowel /æ/. The duration of vowels did not see significant improvements apart from the vowel pair /u/-/ʊ/.

En la actualidad, el reciclaje de materiales es una de las soluciones para combatir la contaminación. Esta investigación reutilizó EPS (poliestireno expandido) y PVC-U (cloruro de polivinilo rígido) en mezclas para fabricar bloques de concreto estructural, analizando su comportamiento en la resistencia a la compresión. Se emplearon porcentajes de sustitución del 10% y 20%, donde el EPS reemplazó al agregado fino y el PVC-U al agregado grueso. Los resultados de propiedades físicas (alabeo, absorción, succión, variabilidad dimensional) cumplieron con las normas RNE E.070 (Reglamento Nacional de Edificaciones – albañilería) y NTP 399.602 (Norma Técnica Peruana – Unidades de albañilería). La resistencia a la compresión del bloque con EPS se redujo en un 14% y 21.63%, mientras que la del bloque con PVC-U disminuyó un 12.69% y 21.79%, pero ambos valores se mantuvieron dentro de lo establecido en la NTP 399.602.
