GENDER AND IDENTITY IN POSTMODERNITY: NASCENT CONSIDERATIONS

It is urgent to reflect on identity and how it can be engendered by personal characteristics. The dichotomy that emerges when it comes to the identity between men and women reveals a segregation in which positive value is attributed to one and negative value to the other, placing the gender binary in our society as a unique condition. To this end, the guiding thread of this article will seek to understand the relations of identity in postmodernity and the relations that gender has in the post-structuralist movement, in a qualitative methodological proposal that encompasses basic texts on gender and identity in which the authors, in a surgent way, weave considerations. From the conception of identities, we see that differentiating individuals is a process imbricated with meanings that reinforces the historical and geographical characteristics to which the subjects are subjected, which presents constant modifications, which gives rise to new identities. With regard to gender, the search for it to become an analytical category crosses the struggle of minorities affected by inequalities in power relations and the resignification of the term so that it does not only differentiate male from female, opening space for new conceptions and categories. The current social construction, therefore, demands that the meanings loaded with absolute truths be remodeled, counterposing modern thought and resignifying identities and gender, to deconstruct the ambiguities and generalizations rooted in each one of us.

Of devotion and disgust: Method, belief and power in anthropological research on religion

In this paper I argue that the method of participant observation is as contingent as it is strategic and that ethnographic fieldwork in a religious field cannot be undertaken justifiably by circumventing the question of personal religious belief, as it is indeed the status of the ethnographer’s belief which facilitates learning in and of the field. I will show that in my field, belief in the guru becomes a modality to partake in the power relations among devotees which characterize the public nature of the devotee gatherings and is a commonly accepted way of being acknowledged as a devotee.

Utilization of Stochastic P-bifurcation for Simultaneous Energy Harvesting and Vibration Suppression: An Experimental Investigation

Abstract This research focuses on the prediction and experimental verification of P-bifurcation as well as the effectiveness in reducing vibrations and harvesting energy with the use of an inertially nonlinear energy harvesting device attached to a single-degree-of-freedom structure subjected to Gaussian broadband base excitation, modeled as white noise. Four experimental scenarios were tested, including three with different resistive loads and one with an open circuit. Frequency domain optimization involved an optimization routine that was designed to minimize the mean squared error in the pendulum velocity's frequency content below two cycles per second while constraining the RMS velocity discrepancy between the simulations and actual experiments to be below 3%. This facilitated accurate predictions of power, vibration suppression, and P-bifurcation. Using the fitted model, an analytically derived P-bifurcation boundary in the noise intensity versus electrical damping plane was presented and experimentally verified. Additionally, power spectral densities for electric power and relative suspended mass velocity were determined for the IPVA system and compared with a top-performing linear system. Results indicated that the monomodal system was the least effective in energy harvesting, while the bimodal and rotational systems significantly enhanced mean and resonant peak power by up to four and two times, respectively. Near the resonant frequency, the peak relative velocity power spectral density decreased by a factor of four, and the mean square relative velocity improved by a factor of two.

The Pacific Islands and Chinese power as presence, influence, and interference

Abstract Dominant debates about China’s growing presence in the Pacific Islands – through infrastructure, aid, trade, and investment – suggest that Chinese material power directly translates to influence and effective interference in Pacific states’ domestic and foreign affairs. These perspectives fail to clarify the causal link between Chinese economic statecraft and Pacific governments’ alignment with Beijing’s interests. They also deny Pacific people agency, overlooking how power relations are mediated by Pacific state and non-state actors operating across complex political and socio-economic structures. We challenge such rationalist conceptualisations of Chinese power by developing a constructivist taxonomy of power as presence (dormant capability), influence (socialisation), and interference (incentives), and applying it to the Melanesian subregion. We argue that Chinese power is not merely material, causal, and unidirectional. Chinese power can also (re)shape the identities and interests of Pacific elites and publics in a constitutive manner, potentially aligning their ideas about substantive norms, rules, and practices guiding their foreign relations with Chinese ‘core interests’ and perspectives on regional and global politics.

Public Computing Intellectuals in the Age of AI Crisis

The belief that AI technology is on the cusp of causing a generalized social crisis became a popular one in 2023. While there was no doubt an element of hype and exaggeration to some of these accounts, they do reflect the fact that there are troubling ramifications to this technology stack. This conjunction of shared concerns about social, political, and personal futures presaged by current developments in artificial intelligence presents the academic discipline of computing with a renewed opportunity for self-examination and reconfiguration. This position paper endeavors to do so in four sections. The first explores what is at stake for computing in the narrative of an AI crisis. The second articulates possible educational responses to this crisis and advocates for a broader analytic focus on power relations. The third section presents a novel characterization of academic computing’s field of practice, one which includes not only the discipline’s usual instrumental forms of practice but reflexive practice as well. This reflexive dimension integrates both the critical and public functions of the discipline as equal intellectual partners and a necessary component of any contemporary academic field. The final section will advocate for a conceptual archetype–the Public Computer Intellectual and its less conspicuous but still essential cousin, the Almost-Public Computer Intellectual–as a way of practically imagining the expanded possibilities of academic practice in our discipline, one that provides both self-critique and an outward-facing orientation towards the public good. It will argue that the computer education research community can play a vital role in this regard. Recommendations for pedagogical change within computing to develop more reflexive capabilities are also provided.

Shared oscillatory mechanisms of alpha-band activity in prefrontal regions in eyes open and closed state using a portable EEG acquisition device

Alpha oscillations are associated with various psychiatric disorders, with many studies focusing on the prefrontal cortex, where transcranial alternating current stimulation (TACS) is applied in the alpha frequency band. This approach often involves selecting individualized alpha frequencies to resonate with their endogenous alpha oscillations. While strong alpha oscillations (8–13 Hz) are typically induced when the eyes are closed, they can also occur during the resting state with eyes open. However, it remains unclear whether these alpha oscillations share a common neural generation mechanism. Exploring which of these alpha oscillations is more suitable as a stable alpha peak frequency is a question of significant interest. Therefore, to systematically study this issue, we specifically collected resting-state electroencephalographic (EEG) data from the prefrontal region of 40 individuals, under both eyes-open and closed- eye conditions, with multiple follow-ups extending up to nine months. Through spectral analysis on each person’s entire dataset and averaging the results, we observed a significant positive correlation between the alpha-band power in the eyes-open and the eyes-closed states, in terms of both absolute power and relative power. Further analysis revealed that this correlation was primarily contributed by the periodic activity within the alpha band. Upon modelling the oscillatory components, we discovered distinct differences in the oscillatory characteristics-such as number of the alpha sub-oscillations between the eyes-open state and the eyes-closed state. Our study is the first to systematically explored the relationship between alpha oscillations in the prefrontal cortex in the eyes-open and eyes-closed states, identifying both shared part of the neural generation mechanism and some distinct neural mechanisms that are unique to each state.

Sustainable Operations of Online and Offline Restaurants: Focusing on Multi-Brand Restaurants

This study investigates the sustainable operations of a multi-brand restaurant that adopts multiple brands in a store, unlike a typical restaurant that operates only a single brand. We introduce five restaurant operation models, including three traditional single-brand ones (offline, online, and multi-channel) and two recent multi-brand restaurants with a single fixed franchise fee and multiple franchise fees proportional to the number of brands. We then investigate the performance of the models in the changing market and cost environments. Through analytical and numerical analyses, we reveal that adopting a multi-brand restaurant does not always guarantee superior profit performance. Such an adoption is recommended under certain conditions, such as when the potential market base is large, consumers are not very price-sensitive, food and delivery costs are low, an increase in food items does not significantly impact process inefficiency, franchise fees are low, or the relative market power of multiple brands is strong. Otherwise, adopting the traditional single-brand restaurant would guarantee better profit performance. Therefore, for a sustainable multi-brand restaurant adoption, it is important to create a business environment that can lower food prices, and a thorough understanding of the decision dynamics related to the number of brands is required.

Exploring the Relationship Between CAIDE Dementia Risk and EEG Signal Activity in a Healthy Population

Background: Accounting for dementia risk factors is essential in identifying people who would benefit most from intervention programs. The CAIDE dementia risk score is commonly applied, but its link to brain function remains unclear. This study aims to determine whether the variation in this score is associated with neurophysiological changes and cognitive measures in normative individuals. Methods: The sample comprised 38 participants aged between 54 and 79 (M = 67.05; SD = 6.02). Data were collected using paper-and-pencil tests and electroencephalogram (EEG) recordings in the resting state, channels FP1 and FP2. The EEG signals were analyzed using Power Spectral Density (PSD)-based features. Results: The CAIDE score is positively correlated with the relative power activation of the θ band and negatively correlated with the MMSE cognitive test score, and MMSE variations align with those found in distributions of EEG-extracted PSD-based features. Conclusions: The findings suggest that CAIDE scores can identify individuals without noticeable cognitive changes who already exhibit brain activity similar to that seen in people with dementia. They also contribute to the convergent validity between CAIDE and the risk of cognitive decline. This underscores the importance of early monitoring of these factors to reduce the incidence of dementia.

The Discretionary Power of Street‐Level Bureaucrats From the Perspective of Illusio

ABSTRACTInterrogating the tension between care and control in the work of social services staff in Belgian immigration detention centres, this article sheds light on the uses of discretion from the perspective of Bourdieu's concept of illusio. I argue that social services staff's use of discretionary power must be understood at the crossroads of their belief in their professional ethos and the power relations within these centres, which enabled them to frame the element of control as something they had to deal with professionally, rather than something to which they contributed. This sheds light on both the uses of discretion as well as on the articulation of care and control in border humanitarianism.

DELirium treatment with Transcranial Electrical Stimulation (DELTES): study protocol for a multicentre, randomised, double-blind, sham-controlled trial.

Delirium, a clinical manifestation of acute encephalopathy, is associated with extended hospitalisation, long-term cognitive dysfunction, increased mortality and high healthcare costs. Despite intensive research, there is still no targeted treatment. Delirium is characterised by electroencephalography (EEG) slowing, increased relative delta power and decreased functional connectivity. Recent studies suggest that transcranial alternating current stimulation (tACS) can entrain EEG activity, strengthen connectivity and improve cognitive functioning. Hence, tACS offers a potential treatment for augmenting EEG activity and reducing the duration of delirium. This study aims to evaluate the feasibility and assess the efficacy of tACS in reducing relative delta power. A randomised, double-blind, sham-controlled trial will be conducted across three medical centres in the Netherlands. The study comprises two phases: a pilot phase (n=30) and a main study phase (n=129). Participants are patients aged 50 years and older who are diagnosed with delirium using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision criteria (DSM-5-TR), that persists despite treatment of underlying causes. During the pilot phase, participants will be randomised (1:1) to receive either standardised (10 Hz) tACS or sham tACS. In the main study phase, participants will be randomised to standardised tACS, sham tACS or personalised tACS, in which tACS settings are tailored to the participant. All participants will undergo daily 30 min of (sham) stimulation for up to 14 days or until delirium resolution or hospital discharge. Sixty-four-channel resting-state EEG will be recorded pre- and post the first tACS session, and following the final tACS session. Daily delirium assessments will be acquired using the Intensive Care Delirium Screening Checklist and Delirium Observation Screening Scale. The pilot phase will assess the percentage of completed tACS sessions and increased care requirements post-tACS. The primary outcome variable is change in relative delta EEG power. Secondary outcomes include (1) delirium duration and severity, (2) quantitative EEG measurements, (3) length of hospital stay, (4) cognitive functioning at 3 months post-tACS and (5) tACS treatment burden. Study recruitment started in April 2024 and is ongoing. The study has been approved by the Medical Ethics Committee of the Utrecht University Medical Center and the Institutional Review Boards of all participating centres. Trial results will be disseminated via peer-reviewed publications and conference presentations. NCT06285721.

Anticolonial co-design: a methodology for including agricultural workers in the development of new AgTech

ABSTRACT Collaborative design (co-design) is becoming a popular method for including end-users in the design process of technologies which may affect them. The research in this paper emerges from an agricultural technology (AgTech) co-design project located in settler colonial state of Aotearoa New Zealand. Inspired by methodological insights from anticolonial science and technology studies (STS), the paper details the authors’ experiences with attempting to include local and migrant agricultural workers within the AgTech co-design project in a way that did not perpetuate colonialism (i.e. was anticolonial). Based on these experiences, the authors identify four practices that can support other researchers wanting to engage in anticolonial co-design: (1) understand the historical context of your research; (2) create a place –and community-based guidelines for technology development; (3) build and maintain strong relationships with collaborators; and (4) be prepared to slow-down or to stop innovation. These practices offer methodological insights into how to do anticolonial co-design within the uneven power relations of settler colonialism and within projects not necessarily designed to engage in anticolonial co-design.

Large-Scale Group Decision Making with Dual Feedback from Community Residents Based on the Organizational Invisible Field

In China, communities function as grassroots self-governing bodies, and the enhancement of public participation in community governance has remained a central focus of study. This paper applies the Large-Scale Group Decision-Making (LSGDM) method to the process of community self-governance and proposes a dual feedback group consensus decision-making model that takes into account the unique social relations among residents. Firstly, the concept of the Organizational Invisible Field—formed in communities by intangible social capital such as positional power and interpersonal relationships within the organization—is introduced. The definition of Invisible Field Force is utilized to measure the influence of these forms of capital on social relationships. Subsequently, drawing on field dynamic theory, the process by which residents’ preferences within the organization are shaped by the action of Invisible Field Force is explored. Secondly, acknowledging that invisible relationships can be affected by dynamic interactions during the decision-making process, the Invisible Field Force change model is constructed. Building on this, a dual feedback consensus coordination mechanism—encompassing both in-organization members and all residents—is designed. Finally, the validity and utility of the model are verified through case studies and sensitivity analyses.

Photodamage prediction model and optimal lighting system for polychrome artworks in museum

When lighting polychrome artworks in museum, the light sources are required not only to provide high-quality visual performance, but also to minimize the photodamage. Currently, though there are mature methods to calculate visual performance, how to predict the degree of photodamage remains a challenge, which leads to a lack of light sources satisfying both visual and protection requirements. Our study conducted a series of 294 accelerated aging experiments spanning over 11 years for materials commonly used in Chinese polychrome artworks, using isoenergetic white-light D55 and 10 different wavelengths of narrow-band light as experimental light sources. The mathematical model predicting the photodamage degree caused by intensity (I), exposure time (t), the relative spectral power distribution of the light source (S(λ)), and the irradiated material's relative spectral responsivity (P(λ)) to polychrome artworks was established, and the mean absolute percentage error of the model, as verified by experiments, was 11.63 %. Combined with the existing visual performance calculation methods, an optimal lighting algorithm that simultaneously meets high-quality visual performance and minimum photodamage was developed, followed by developing a new Spectrally Tunable White LEDs (STWLEDs) lighting system with 10 LED chips. It is found that the STWLEDs can adjust and output the optimal spectra and recommended illuminance according to the characteristics of polychrome artworks, thus realizing lighting with minimum photodamage, meanwhile, satisfying high-quality visual performance. After testing, as well as satisfying the requirements of visual performance, the average photodamage is reduced by 40.95 % with STWLEDs compared with the traditional WLEDs.

Development of a Tumor Growth-responsive Robust Planning Method for Head and Neck Cancer in Carbon-ion Radiotherapy.

The current study aimed to evaluate a treatment planning method that is robust against tumor growth and to assess its effectiveness in particle therapy for head and neck cancer. The proposed method optimizes dose distribution by replacing the relative stopping power ratio (rSPR) of the clinical target volume (CTV) cavity region with a tumor-equivalent rSPR (Condition 1). The optimized initial treatment plan template was then recalculated using in-room CT images acquired in the same treatment position, and the doses to the tumor and organs at risk were compared with those in the initial treatment plan. We evaluated this method in 10 patients with head and neck cancer treated with carbon ion radiotherapy. To evaluate the effectiveness of the proposed method, we compared it to the initial treatment plan without the replacement (Condition 2). CTV V95% reduction relative to that of the initial treatment plan at the end of treatment was 1.3%±2.9% and 2.6%±3.7% for Condition 1 and Condition 2, respectively, with Condition 1 (Replacement condition) providing better CTV coverage. Subgroup analysis showed a higher change in target coverage in the mucosal melanoma than in the adenoid cystic carcinoma, suggesting that this was influenced by the rate of tumor growth. The proposed treatment planning method, which adjusts for tumor growth by modifying the rSPR in the cavity region, improved robustness in carbon ion radiotherapy for head and neck cancer. Condition 1 (with replacement) achieved better CTV coverage than Condition 2 (without replacement), particularly in fast-growing tumors like mucosal melanoma. This method ensures consistent dose delivery to tumors while maintaining safe doses to organs at risk, offering potential for improved treatment outcomes.

Equal Despite Different Entitlements? M.C. Piepers’ Ambiguous Conceptualization of Legal Equality (1898)

In ‘Gelijkstelling van Vreemde Oosterlingen met Europeanen’ (‘Legal Equation of Foreign Asians with Europeans’), published in 1898 in Tijdschrift voor Nederlandsch-Indië, the liberal intellectual M.C. Piepers argued against the legal equation of the resident Japanese subjects in the Netherlands Indies with the Europeans. To make such equation happen, Parliament in the Netherlands discussed a change in the Law in order to alter the provisions with respect to the binary colonial distinction between Europeans and all other people in the Netherlands Indies as laid down in article 109 of the ‘colonial constitution’ (‘regeringsreglement’) of 1854. The change was needed for the 1896/1897 trade-agreement between the Netherlandic Empire and Imperial Japan to be implemented. Piepers warned against this ‘surrender’ to Japanese claims, arguing that the change emerged from a wide-spread misunderstanding of the legal and constitutional regulations with respect to legal entitlements in the Netherlands Indies. This article interprets Piepers’ passionate defense of the judicial status quo concerning equality founded on ‘legal’ definitions of difference, as an avant la lettre constitutional ‘apartheid’ argument. Piepers’ view on Netherlands Indies state formation started from a legal pluralism with subjectively defined groups. We will argue how in these subjectivities resonate three levels of power relations around 1900: a) geopolitical; b) national/state/colonial c) individual; with long-living aftermaths. Piepers final line of defending the status quo is the distinction between the just de jure equality in colonial society and the unjustified de facto hierarchical relationships between the different population groups. This very opposition between just laws and unfair practices in colonial governance obscures how the Eurocentrism of European (liberal) legal thought inevitably resulted in racist practice

Racing Demands for Winning a Grand Tour: Differences and Similarities Between a Female and a Male Winner.

To describe and compare the race characteristics, demands, and durability profile of a male and a female Grand Tour winner. Overall and stage-type-specific (ie,time trials, flat, semimountainous, and mountain) demands and race characteristics during 2 Grand Tours were determined and compared between the female and male cyclists. In addition, relative power output distribution and pacing, percentage of functional threshold power (FTP), and changes in maximal mean power outputs (MMPs) with increasing levels of kilojoules burned were determined. Although many differences were found between course and absolute racing demands between the male (FTP: 413W; critical power: 417W) and female (FTP: 297W; critical power: 297W) cyclists, similar power distributions and pacing strategies were found if data were expressed relatively. However, the female cyclist rode a higher percentage of her FTP during the first 2 quarters of flat stages (14.7%-15.1%) and the last quarter of mountain stages (9.8%) than the male cyclist. Decrements in MMPs were only observed after burning 30kJ·kg-1 in the female and 45kJ·kg-1 in the male Grand Tour winner. Both the male and female Grand Tour winners produced very high 20- to 60-minute MMPs, whereas decrements in MMPs were only observed after having burned 75% (female) and 80% (male) of total kilojoules burned during a stage. These are the latest and lowest in MMPs reported in the scientific literature and highlight the importance of durability in combination with excellent climbing and time-trial skills, which are needed to be able to win a Grand Tour.

Unveiling power dynamics in Latin American economic education: A Foucauldian analysis of development economics discourses

This study explores Latin American perspectives on heterodox economic development by analyzing 23 development economics syllabi and conducting 37 semi-structured interviews with educators and students. Using a Foucauldian framework and an Archaeology of Knowledge approach, this research uncovers regional viewpoints and variations in course content. Results highlight the dominance of the neoclassical paradigm in syllabi and diverse opinions on development. This study provides nuanced insights into the coexistence of orthodox and heterodox paradigms in Latin America, revealing complex dynamics and power relations within economic education and the broader discourse on development in the region.

Lessons from Founding a College: A Personal Perspective

“Higher education is in a critical period with a potential for rebalancing of internal and external relations of authority, power and responsibility in higher education governance. An important element in this transition has been a growing policy focus on the contributions of higher education institutions are expected to make to economic growth, job creation and innovation.”‐ Peter Maassen, “A New Social Contract for Higher Education?”

Visuelle Beeinträchtigung in der Kontaktlinsenpraxis

Purpose. The aim of this case report is to describe the treatment of myopic eyes with pathological reduced vision. A contact lens and a spectacle lens build a telescope and the associated magnification helps to increase vision acuity. Material and Methods. The myopic not presbyopic eyes (−3.00 D) were overcorrected by −7 D with bitoric, spherical, rigid contact lenses, base curve = 8.00/7.65 mm, back-vertex-power = −10.00/−12.00 D, over-all diameter = 10.4 mm. The refractive compensation with the spectacle lens, back-vertex-power = +6.50 D (corneal-vertex-distance 12.0 mm), front-surface-power = +7.50 D, refractive index = 1.50, over-all diameter = 65 mm, centre thickness = 7.10 mm together with contact lens build a Galilean type telescope with a maximum of magnification power. Results. The magnification power of the telescope was Vs = 1.091, the magnification power of the spectacle lens was Ve = 1.037 and the related total magnification power was Vg = 1.131. The telescope increased the binocular distance vision acuity from 0.40− to 0.63 and the binocular near vision acuity from 0.32+ to 0.40+. Conclusion. The Galilei system described is suitable for improving visual acuity in the case of special visual impairments.

Assessing the Effect of Short-Term Interval Training on Acceleration Ability and Anaerobic Power of Novice Sprinters

Background. Acceleration ability and anaerobic power are critical determinants of sprinting performance, particularly for novice sprinters. Objectives. The purpose of the study was to examine the effects of a four-week interval training program on acceleration ability and anaerobic power among novice sprinters. Materials and methods. A within-subjects quasi-experimental design was used to fulfil the study’s objectives. A total of fifteen participants (age: 20.5 ± 1.4 years) underwent baseline assessments of acceleration ability (50 m dash) and anaerobic power (Running-Based Anaerobic Sprint Test). The adopted progressive interval training protocol consisted of four weekly sessions conducted over a four-week period, focusing on striding, high knees, single-leg hops, curve sprints and double-leg jumps to enhance acceleration ability and anaerobic power. Results. Following the intervention, significant improvements were observed in acceleration ability over a distance of 10 m (pre: 2.14 ± 0.16 s, post: 2.02 ± 0.14 s, p < 0.05, Cohen’s d = 1.02) and 20 m segments (pre: 3.47 ± 0.23 s, post: 3.32 ± 0.20 s, p < 0.05, Cohen’s d = 0.78), indicating moderate to large effect sizes. However, no considerable enhancements were found in anaerobic power parameters (average power, maximum power, minimum power, fatigue index, relative peak power, and anaerobic capacity) at the post-intervention stage (p > 0.05). Conclusions. The study highlights the effectiveness of the interval training protocol in enhancing initial acceleration among novice sprinters, although it suggests a limited impact on anaerobic power within the study period. Further research should investigate the longer-term effects and tailored training approaches to optimize comprehensive sprint performance strategies.
