Epidemiologic evidence on the association between dietary choline and betaine and mortality risk remains limited, particularly among non-Western populations. We examined the association of dietary choline and betaine with all-cause mortality in Chinese adults using data from the China Health and Nutrition Survey (CHNS) 1991-2015. We included 9,027 men and 8,828 women without cardiovascular disease and cancer at baseline. Dietary intake was assessed using 3-day 24-hour dietary recalls in combination with a household food inventories. Death was ascertained through household surveys in each wave. We used time-dependent Cox proportional hazards regression models to estimate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs). During a median follow-up of 9.1 years, 891 men and 687 women were deceased. Higher total choline intake was associated with a lower risk of all-cause mortality in both men [HRQ5 vs. Q1 = 0.58 (95% CI: 0.45, 0.74)] and women [HRQ5 vs. Q1 = 0.59 (95% CI: 0.44, 0.78)]. The dose-response curve followed a reverse J-shape in men and an L-shape in women (both P-nonlinear ≤ 0.005). Similarly, fat-soluble choline intake was inversely associated with the risk of all-cause mortality in both men [HRQ5 vs. Q1 = 0.59 (95% CI: 0.46, 0.75)] and women [HRQ5 vs. Q1 = 0.53 (95% CI: 0.40, 0.70)], showing reverse J-shaped patterns (both P-nonlinear < 0.001). A J-shaped association between dietary water-soluble choline and all-cause mortality was observed in women (P-nonlinear < 0.001), but a null association was found in men. Betaine intake was not associated with all-cause mortality in either sex. Our findings suggest that adequate choline intake, but not betaine, is linked to reduced all-cause mortality in Chinese adults with predominantly plant-based diets, with both insufficient and excessive choline intake potentially increasing mortality risk.

Ce numéro spécial est le résultat de la collaboration entre les membres du Groupe de recherche interuniversitaire sur la normativité (GRIN) durant l’année 2023-2024. Principalement situé dans les universités de l’île de Montréal, ce groupe a pour objectif d’explorer le thème de la normativité en philosophie selon trois axes principaux : normativité et société, normativité et affectivité, normativité et connaissance. Une visée commune s’est progressivement révélée au fil de nos rencontres : dévoiler de manière critique les différentes sortes de normativité qui ont été soit oubliées, soit ignorées. Cela nous a donc laissé croire que certaines normes pourraient avoir été perdues de vue, et c’est de là que nous sont venus le titre et le thème de ce numéro spécial : « À la recherche des normes perdues ». La présente introduction donne un aperçu des huit articles qui forment le numéro.

This paper presents a compact, dual-polarized, 32-element, 47 GHz phased array transceiver, fabricated in 55 nm CMOS technology with antenna in package (AiP) technology for 5G communications. The proposed transceiver employs an intermediate frequency (IF) phase-shifting architecture and a facing-up (FU) configuration AiP. The IF phase shifting is realized using a bidirectional IF vector sum phase shifter and IQ mixer with drain bias, achieves less than 1° phase resolution, with rms phase error of 0.047° and rms amplitude error of 0.063 dB. The output third-order intercept point is above +1.0 dBm with Txconversion gain of more than 16.5 dB over the radio frequency ranges from 46 to 49 GHz. To reduce heat concentration from the high integrated phased-array transceiver, a FU AiP-fan-out wafer-level packaging utilizes solder balls mounted on the package as a heat spreader, resulting in a thermal resistance of less than 0.3 K/W. The finalized AiP size is only 12.3 mm × 14.9 mm. Regarding the over-the-air measurement, the proposed transmitter can deliver an equivalent isotropic radiated power of 30.7 dBm with single polarization and demonstrates transmitter error vector magnitude less than 3.9% under 5G NR modulation scheme (256QAM, 100 MHz bandwidth).

This study examines the impact of organizational gossip on workplace outcomes, including affective organizational commitment, loneliness, and turnover intention, with a focus on differences between the public and private sectors. Using a mixed-methods approach, the research combines qualitative and quantitative data from surveys conducted with Turkish citizen partners and in-depth interviews with employees in both sectors. The findings reveal that positive gossip enhances social bonds and commitment, while negative gossip leads to loneliness and increased turnover intention, especially in the private sector where job insecurity is higher. The study introduces an integrated framework linking gossip dynamics to organizational processes. Practical implications suggest that managers should address negative gossip while promoting positive gossip to strengthen workplace relationships. This study highlights the dual role of gossip in shaping employee experiences and retention strategies.

Carissa Véliz (2021) soutient que pour être un agent moral, une entité (comme un système algorithmique) doit nécessairement être sentiente. En prenant l’exemple d’une forme d’agentivité sans conscience phénoménale et donc sans sentience, je conteste cette thèse. En effet, certains groupes humains peuvent être considérés comme des agents intentionnels non réductibles aux individus particuliers qui les composent. En m’appuyant sur l’interprétativisme proposé par Uriah Kriegel (2011) et John Haugeland (1990), ainsi que sur la posture intentionnelle (intentional stance) de Daniel Dennett (1987), je montre que l’intentionnalité est une condition suffisante pour parler d’agentivité morale et que, contrairement à ce qu’affirme Véliz, il peut donc y avoir des agents moraux qui ne sont pas sentients.

World heritage has become UNESCO’s flagship programme, and it is a site of active state engagement. At the crux of that engagement is the prestigious World Heritage List. This engagement is regularly analysed as pursuits of national prestige. In this article, I advance a Bourdieusian analysis of world heritage as a field that generates international cultural prestige. I identify humanity as the field’s doxa that allows for a vertical separation and the generation of more-than-national cultural value. I show how states’ desire for this prestige jeopardised the field’s autonomy at a critical juncture in 2010 and analyse the field’s aftermath as involving fraught attempts by states to discursively reconstruct the field’s vertical and functional separations in the quest for international cultural prestige. This reconstruction involves nothing less than reinterpreting humanity as the community-of-states, pointing at once to humanity’s indispensability for more-than-national value and undermining its ability to generate that value.

We report on an experience with impostor research participants, people who misrepresent themselves, and identify characteristics that can be used by investigators to screen out such participants. We compare the responses of impostor and valid participants, showing that impostors meaningfully change qualitative study findings with implications for policy interventions or follow-on research informed by the study. It is important for investigators to be alert to the potential for impostor participants and plan their research accordingly.

La critique de John L. Austin contre le représentationnalisme en philosophie de la perception l’a mené à soutenir que les sens sont « muets », c’est-à-dire qu’ils ne nous fournissent aucun contenu conceptuel. Cette thèse a été reprise par Charles Travis et Jocelyn Benoist, qui y voient tous les deux une raison d’abandonner toute conception normative de la perception. Si la thèse du mutisme des sens prescrit en effet un rejet du caractère conceptuel de la perception, le présent article s’efforce toutefois de montrer que la tendance à en déduire que la perception exclut toute norme relève en fait d’une radicalisation de la thèse originale d’Austin.

Semantic transparency is usually defined as the extent to which the lexical meaning of a morphologically complex word can be inferred from its structure and constituents. Recent studies have emphasized the need to distinguish two aspects of transparency: relatedness (i.e. the degree to which the meaning of lexical constituents is retained in that of a complex word) and compositionality (i.e. the degree to which the meaning of a complex word is determined by the meaning of its constituents and the way they are combined). In this paper, we investigate the influence of a variety of linguistic factors on both relatedness and compositionality. Our objective is twofold, as we seek to (i) determine more precisely the impact of lexical and morphological properties on transparency and (ii) better understand the distinction between relatedness and compositionality based on their respective determinants. The study focuses on deverbal nouns in French and estimates relatedness and compositionality based on human judgments and computational methods. The results indicate that the frequency and ambiguity of bases and derivatives, as well as the productivity and polyfunctionality of nominalizing suffixes, have different effects on relatedness and compositionality. They confirm the relevance of the distinction between the two aspects of transparency.

This paper presents the design of a phase gradient metasurface lens (MSL) that enables the orbital angular momentum (OAM) beam convergence alleviating the limitations of the OAM beams in far-field wireless communication. An MSL of a specific constitutive electromagnetic parameter, i.e., relative refractive index, in front of a traditional Uniform Circular Array is designed at 10 GHz. In the presence of the lens, the beam converges from 58∘ to 24∘ for +1 and –1 OAM modes. The proposed MSL can also be used for second-order (±2) OAM modes. The experimental verification performed on the laboratory prototype agrees well with the simulated results. The purity analysis also confirms that the OAM beams passing through the lens maintain high mode purity, thereby not disturbing the phase distribution in the corresponding OAM modes. The designed lens can be used in point-to-point and defense communications.
