“Beyond the kitchen door”: Racialised female domestic labourer’s mobility experiences in Anna Muylaert’s The Second Mother
No full textThe successful Brazilian fictional film The Second Mother (Que horas ela volta?, 2015), directed by Anna Muylaert, illustrates that mobility is chiefly limited or stagnant for the main character, Val (Regina Case), a live-in racialised female domestic labourer who migrates from the Brazilian northeast to the southeast to work in the house of a wealthy family in São Paulo. However, the film subtly shapes Val’s mobility as a more active, unrestrained experience once her daughter arrives in town ten years later. My goal is to understand the fundamental factors influencing Val’s range of motions. Building upon on the cultural geography notion of mobility as a socially produced movement of time and space, I look at how control over Val’s ability to move derives from the embodiment of practices of power built on derogatory discourses around the ideas of the doméstica (“maid”) and the domestic spatial and interpersonal emotional relations ingrained in class, gender, and the racial dimensions of Brazil’s former colonial, plantation-based patriarchal society. On the other hand, Val begins to disembody the powerful practices that previously controlled her mobility. I argue that the spatial, social, emotional, and bodily mobility gained by Val, echoing the Brazilian period of empowerment for the working classes, reflects gains from law such as PEC das Domésticas EC 72/2013 and Lei Complementar 150/2015
Teaching Digital Humanities: Neoliberal logic, class, and social relevance
No full textThe digital humanities have a class problem. This is not to say that other disciplines are immune from socioeconomic disparities, but that DH is a space in which students, across all stages of education, benefit from access to resources that would not normally be a necessity in the arts and humanities. To succeed in the digital humanities often requires privileged knowledge and resources, access to expensive equipment, software, expertise and training networks that remain beyond the reach of many students and their institutions. Many students do not have access to computers capable of performing substantial analytics, or they attend institutions where licensed platforms commonplace in DH are not provided. Many students do not have access to digital libraries providing readings and datasets, or cannot afford the majority of the field’s major publications, still in print and quite expensive. Many students do not have the resources to attend the field’s many training networks, and many students, in this age of remote learning and working, do not even have sufficient bandwidth to engage with DH through web-based tools and communities. Education is always subject to the dynamics of class, but the humanities before the digital turn were at least a space through which social relations could be challenged, relatively free of the cultural logic and resource requirements that heighten inequalities
How do mental health professionals use humor? A systematic review
No full textAlthough the value of humor is appreciated in mental health care, little is known about how professionals employ humor. The purpose of this systematic review was to explore how mental health professionals use humor. Academic databases were systemically searched. Papers were subjected to quality appraisal. Ten studies met eligibility criteria. Mental health staff used humor to cope with stress and adversity. They also used humor to enhance relationships with service users, and to erode team-related power dynamics. It was suggested that knowing when to use humor appropriately was dependent on experience and how well staff knew service users. However, it was also found that staff’s use of humor was sometimes negatively perceived by service users, as it could reinforce power dynamics. Due to the limited and low level of evidence, it is recommended that rigorous research in the area of humor in mental health practice is undertaken
Regioselective partial hydrogenation and deuteration of tetracyclic (Hetero)aromatic systems using a simple heterogeneous catalyst
No full textThe introduction of added ‘3-dimensionality’ through late-stage functionalization of extended (hetero)aromatic systems is a powerful synthetic approach. The abundance of starting materials and cross-coupling methodologies to access the precursors allows for highly diverse products. Subsequent selective partial reduction can alter the core structure in a manner of interest to medicinal chemists. Herein, we describe the precise, partial reduction of multicyclic heteroaromatic systems using a simple heterogeneous catalyst. The approach can be extended to introduce deuterium (again at late-stage). Excellent yields can be obtained using simple reaction conditions
The Importance of a House and the pandemic formation of the ATLFilmParty community
No full textThis article discusses the short films of the Atlanta-based black American filmmaker Olamma Oparah. Oparah’s film The Importance of a House was the winner of the inaugural ATLFilmParty (AFP) free film competition and industry networking event created by Brooke Sonenreich in the summer of 2021. Produced and directed in the era of both the COVID-19 pandemic and the aftermath of the US racial reckoning after the murder of George Floyd, The Importance of a House iterates the home as a site of refuge. This article analyses Oparah’s short in the context of two other films she directed in the same period, Laundry Day and No One Heals Without Dying that similarly explore the meaning of home as a black, female, and spiritual space. Using an object-oriented and artist-centered methodology informed by the author’s work with the liquid blackness research group, this article argues that Oparah’s films as texts speak to the contextual needs that AFP meets in fostering a local and independent home for filmmakers in Atlanta facing global Hollywood’s increasingly dominant presence in the city and the region
Nanoscratch on single-layer MoS2 crystal by atomic force microscopy: semi-circular to periodical zigzag cracks
No full textThe fracture behaviors of single-layer molybdenum disulfide (MoS2) grown on SiO2/Si wafer by chemical vapor deposition (CVD) were systematically investigated here via a technique that combining AFM-based nanoscratch tests with friction force microscopy (FFM). To get a complete cognition of fracture behavior and deepen the understanding of different fracture stages in the process, nanoacratch with progressive and constant force was done step by step. The radius of AFM tip we used is similar to 10 nm which is relatively blunt to produce a tensile fracture rather than pierce the film at the initial stage. As a result, there were novel crack modes with specific normal load in the surface of CVD-grown MoS2 : semi-circular and periodical zigzag cracks, and both crack modes exhibit anisotropy during the generation and propagation. The scratch study of single-layer MoS2 film has exhibited the gradual process of fracture behavior on nanoscale layered films and confirmed the mesoscopic anisotropy of the mechanical failure of 2D materials
Nebulised delivery of RNA formulations to the lungs: From aerosol to cytosol
No full textIn the past decade RNA-based therapies such as small interfering RNA (siRNA) and messenger RNA (mRNA) have emerged as new and ground-breaking therapeutic agents for the treatment and prevention of many conditions from viral infection to cancer. Most clinically approved RNA therapies are parenterally administered which impacts patient compliance and adds to healthcare costs. Pulmonary administration via inhalation is a non-invasive means to deliver RNA and offers an attractive alternative to injection. Nebulisation is a particularly appealing method due to the capacity to deliver large RNA doses during tidal breathing. In this review, we discuss the unique physiological barriers presented by the lung to efficient nebulised RNA delivery and approaches adopted to circumvent this problem. Additionally, the different types of nebulisers are evaluated from the perspective of their suitability for RNA delivery. Furthermore, we discuss recent preclinical studies involving nebulisation of RNA and analysis in in vitro and in vivo settings. Several studies have also demonstrated the importance of an effective delivery vector in RNA nebulisation therefore we assess the variety of lipid, polymeric and hybrid-based delivery systems utilised to date. We also consider the outlook for nebulised RNA medicinal products and the hurdles which must be overcome for successful clinical translation. In summary, nebulised RNA delivery has demonstrated promising potential for the treatment of several lung-related conditions such as asthma, COPD and cystic fibrosis, to which the mode of delivery is of crucial importance for clinical success
‘I would love to do something about it’: young men’s role in addressing violence against women in Ireland
No full textThis article reports on how young people (aged 18–24) and stakeholders working in the area of violence against women (VAW) in Ireland, perceive young men’s role in addressing VAW. We find that men are considered well positioned to intervene as active bystanders and to engage in feminist allyship. However, several barriers to men’s active bystanding and engagement with the issue of VAW, as well as ethical, theoretical and practice issues, need to be considered. These include: the privileging of men’s willingness to listen to other men, thereby devaluing women’s perspectives; pluralistic ignorance where men feel other men do not share their discomfort of violence-supportive practices; and a tendency for men to default to confrontational modes of active bystanding. We highlight how these issues are even more pertinent to address given the presence of political forces that seek to stymie men’s support for feminist activism and causes related to gender politics
Synthesis of millimeter-sized Mo x W (1− x ) S 2 y Se 2(1− y ) monolayer alloys with adjustable optical and electrical properties and their magnetic doping
No full textAlloying has emerged as an effective approach for elec/optoelectronics applications by modulating the bandgap engineering of two-dimensional (2D) transition metal dichalcogenides (TMDs). Based on our earlier liquid phase edge epitaxy (LPEE) method, we have grown millimeter-sized quaternary MoxW(1-x)S2ySe2(1-y) monolayer films and MoxW(1-x)S2ySe2(1-y) monolayers with different morphologies by controlling the growth temperature and time. The homogeneity and good crystallinity of as-grown alloys are demonstrated by energy-dispersive spectroscopy (EDS), elemental mapping, Raman mapping, and high-resolution transmission electron microscopy (HRTEM). Atomic-resolution scanning transmission electron microscopy (STEM) strongly demonstrates the uniform distribution of Mo, W, S, and Se. Furthermore, alloy-based field-effect transistors (FETs) displaying bipolar conduction behavior with a weak p-branch and conduction behavior show component-dependent properties. In addition, this strategy has been broadened to prepare M-doped MoxW(1-x)S2ySe2(1-y) monolayers (M: Fe, Co, and Ni) for the first time, where magnetic hysteresis (M-H) measurements indicated room temperature ferromagnetism of MoxW(1-x)S2ySe2(1-y). Therefore, the synthesized pristine and M-doped alloys have greatly enriched the family of 2D materials and are prospective candidates for applications in future industrial device applications
