The Partnership of Patriarchy and Capitalism in Cho Nam-joo’s Kim Jiyoung, Born 1982

Socialist feminism, which emerged in the 1970s, aims to solve female oppression and make a comprehensive and innovative understanding of gender, class, capitalism, and male domination. As the mainstay of the socialist feminist school, the ideas of Hartmann and Young make significant contributions to the development of the theory. Hartmann first proposed dual systems theory, and Young published her single system response shortly after. To a certain extent, Young’s new thinking and questioning of dual systems theory also supplement and go into some of the arguments by Hartmann that are not clear enough. Kim Jiyoung, Born 1982 is an English-translated novel written by contemporary South Korean writer and screenwriter Cho Nam-joo. The novel was translated into English by award-winning translator Jamie Chang in 2020. The plight of women highlighted in this novel caused widespread controversy in the international community, especially in East Asian countries. This article examines the oppression of women in Kim Jiyoung, Born 1982, by the long-term interaction between patriarchy and capitalism. This study adopts a research method combining theoretical interpretation and close reading of the text. It addresses the research gap by focusing on a new perspective on the causes of Cho’s female characters’ oppression through the dual systems theory by Hartmann.

Musical consumption, self-control and smartphone addiction: a dual-systems theory perspective and evidence from a survey study

PurposeIn the past decade, smartphone adoption has reached almost 100% in industrialized countries, which is predominantly due to advancements in capabilities. Given the increasing number of people who are addicted to the smartphone and the significant growth of people who consume music via the smartphone, the purpose of the study is to explore the underlying mechanisms through which musical consumption affects smartphone addiction.Design/methodology/approachBased on dual-systems theory, a research model was developed to determine the impact of System 1 (emotion related to music) and System 2 (self-control) on smartphone addiction. A partial-least-squares approach was used to test the model with 294 survey participants.FindingsThe empirical data confirmed the research model. Regarding System 1, musical emotion positively influenced smartphone addiction through musical consumption and musical response. Moreover, musical preference significantly affected musical response. Regarding System 2, self-control negatively predicted smartphone addiction.Research limitations/implicationsThe study is limited, as the participants were college students who are not representative of all populations.Originality/valueThe study extends the literature on the dark side of information technology use and complements a research agenda by Gefen and Riedl (2018) on consideration of music in information systems (IS) research.

A New Method to Solve Dual Systems of Fractional Integro-Differential Equations by Legendre Wavelets

The method that will be presented, is numerical solution based on the Legendre wavelets for solving dual systems of fractional integro-differential equations (FIDEs). First of all we make the operational matrix of fractional order integration. The application of this matrix is transforming FIDEs to a system of algebric equations. By this changing, we are able to solve it by a simple solution. In this way, the Legendre wavelets and their operator matrix are the most important keys of our solution. After explaining the method we test on some illustrative examples which numerical solutions of these examples demonstrate the validity and applicability of suggested method.

Capacitive interdigitated system of high osteoinductive/conductive performance for personalized acting-sensing implants

Replacement orthopedic surgeries are among the most common surgeries worldwide, but clinically used passive implants cannot prevent failure rates and inherent revision arthroplasties. Optimized non-instrumented implants, resorting to preclinically tested bioactive coatings, improve initial osseointegration but lack long-term personalized actuation on the bone–implant interface. Novel bioelectronic devices comprising biophysical stimulators and sensing systems are thus emerging, aiming for long-term control of peri-implant bone growth through biointerface monitoring. These acting-sensing dual systems require high frequency (HF) operations able to stimulate osteoinduction/osteoconduction, including matrix maturation and mineralization. A sensing-compatible capacitive stimulator of thin interdigitated electrodes and delivering an electrical 60 kHz HF stimulation, 30 min/day, is here shown to promote osteoconduction in pre-osteoblasts and osteoinduction in human adipose-derived mesenchymal stem cells (hASCs). HF stimulation through this capacitive interdigitated system had significant effects on osteoblasts’ collagen-I synthesis, matrix, and mineral deposition. A proteomic analysis of microvesicles released from electrically-stimulated osteoblasts revealed regulation of osteodifferentiation and mineralization-related proteins (e.g. Tgfb3, Ttyh3, Itih1, Aldh1a1). Proteomics data are available via ProteomeXchange with the identifier PXD028551. Further, under HF stimulation, hASCs exhibited higher osteogenic commitment and enhanced hydroxyapatite deposition. These promising osteoinductive/conductive capacitive stimulators will integrate novel bioelectronic implants able to monitor the bone–implant interface and deliver personalized stimulation to peri-implant tissues.

Addressing social polarization through critical thinking: Theoretical application in the “Living Well With Difference” course in secondary schools in England

Responding to international calls for critical thinking programs to address social polarisations and extremism through education, this article examines the cognitive and socio-psychological foundations of a critical thinking programme for secondary schools in England called “Living Well With Difference” (LWWD). The aim of LWWD is to develop critical thinking about issues of social polarisation, prejudice and any kind of extreme thinking. These issues often involve the interaction of emotion and thinking, which is understood using a dual systems framework, illustrated with examples of course methodology and content. The learning process aims to promote more cognitively flexible, complex and integrated thinking, measured by integrative complexity, and is supported by meta-awareness to enable emotion management. The aim is for participants to engage with difficult social issues through structured group activities, while becoming aware of social, emotional, textual, visual and rhetorical influences to increase Media Information Literacy, as a foundation for engaging with differing perspectives in order to reduce barriers between groups in society.

Two Ubiquitin-Activating Systems Occur in Plants with One Playing a Major Role in Plant Immunity

Many plants possess two or more ubiquitin-activating enzymes (E1). However, it is unclear whether the E1s of a plant genome play equivalent roles in various pathways. Here we report that tomato and tobacco encode dual ubiquitin-activating systems (DUAS) in which the E1s UBA1 and UBA2 display differential specificities in charging four groups of E2s.The C-terminal ubiquitin-folding domain of the E1s play a major but not sole role in determining the differential specificities of charging the four groups E2s. The dual systems do not play equivalent roles in plant immunity, with silence of UBA2 only compromising host immunity. Among the differentially charged E2s, group IV members UBC32, UBC33 and UBC34 are shown to be essential for ER-associated protein degradation (ERAD) and plant immunity. Like tomato, Arabidopsis UBC32/33/34 E2 triplet are also differentially charged by its E1s and are essential for plant immunity. Loss of function in Arabidopsis UBC32, UBC33 and UBC34 does not affect flg22 and elf18-triggered inhibition of seedling growth but results in alteration of ER stress tolerance, which likely contribute to the diminished plant immunity in the mutants. Our results uncover DUAS in plants and a previously unknown E1?ERAD-associated E2 triplet module in the regulation of host immunity.
