In this article, the question of whether the Löwner partial order on the positive cone of an operator algebra is determined by the norm of any arbitrary Kubo–Ando mean is studied. The question was affirmatively answered for certain classes of Kubo–Ando means, yet the general case was left as an open problem. We here give a complete answer to this question, by showing that the norm of every symmetric Kubo–Ando mean is order-determining, i.e., if $A,B\in \mathcal B(H)^{++}$ satisfy $\Vert A\sigma X\Vert \le \Vert B\sigma X\Vert $ for every $X\in \mathcal {A}^{{++}}$, where $\mathcal A$ is the C*-subalgebra generated by $B-A$ and I, then $A\le B$.

First we give a counterexample showing that recent results on separate order continuity of Arens extensions of multilinear operators cannot be improved to get separate order continuity on the product of the whole of the biduals. Then we establish conditions on the operators and/or on the underlying Riesz spaces/Banach lattices so that the extensions are order continuous on the product of the whole biduals. We also prove that all Arens extensions of any regular multilinear operator are order continuous in at least one variable and we study when Arens extensions of regular homogeneous polynomials on a Banach lattice $E$ are order continuous on $E^{**}$.

The effects of chemical treatment on the radiation-shielding properties of Philippine natural zeolites were investigated using EpiXS following the EPICS2017 library. The zeolites were studied using X-ray diffraction and energy-dispersive X-ray spectroscopy. The acid treatment eliminated Fe and Ca, having a negative impact on the cross-section of the HCl-modified zeolite. The mass attenuation coefficients of the raw, NaOH- and HCl-modified zeolites at 1332 keV were 0.0545, 0.0544 and 0.0548 cm2 g–1, respectively. At 100–10,000 keV, the linear attenuation coefficient depends on the density and increases in the order HCl-modified > NaOH-modified > raw zeolite. In the energy range of 100–16,000 keV, the mean free path and half-value layer values are in the order of HCl-modified < NaOH-modified < raw zeolite. The raw and NaOH-modified zeolites have comparable effective atomic numbers, whereas the HCl-treated zeolite has significantly lower such values.

Partial anomalous venous connection with sinus venosus atrial septal defect is repaired with different approaches including the Warden procedure. Complications include stenosis of the superior caval vein and pulmonary venous baffle; however, cyanosis is rarely seen post-operatively. We report a patient presenting with cyanosis 5 years after a Warden, which was treated with a transcatheter approach.

Systemic inflammation may contribute to the initiation and progression of type 2 diabetes mellitus (T2DM) through diet and lifestyle. We examined the association of dietary inflammation score (DIS), lifestyle inflammation score (LIS) and dietary and lifestyle inflammation score (DLIS) with T2DM and cardiometabolic risk factors among Iranian adults. In this study, we identified and recruited 619 patients with T2DM and 2113 without T2DM from 35 to 75 years old men and women in the baseline phase of the Sabzevar Persian Cohort Study. Using a validated 115-item semi-quantitative FFQ, we calculated a 19-component DIS and a 3-component LIS weighted by circulating inflammation biomarkers. The DIS, LIS and DLIS associations with diabetes were assessed by multivariable logistic regression analysis. The average age of the participants was 48·29 (sd 8·53) (without T2DM: 47·66 (sd 8·42); with T2DM: 50·44 (sd 8·57)). Individuals in the highest compared with the lowest tertiles of DLIS (OR: 3·40; 95 % CI 2·65, 4·35; Ptrend < 0·001), DIS (OR: 3·41; 95 % CI 2·66, 4·38; Ptrend < 0·001) and LIS (OR: 1·15; 95 % CI 0·90, 1·46; Ptrend = 0·521) had an increased risk of T2DM. For those in the highest relative to the lowest joint DIS and LIS tertiles, the results were OR: 3·37; 95 % CI 2·13, 5·32; Pinteraction < 0·001. No significant associations were found between DLIS and cardiometabolic risk factors, including blood pressure, liver enzymes and glycaemic and lipid profiles, except for waist circumference (P < 0·001) and waist-to-hip ratio (P = 0·010). A higher DIS and DLIS score was associated with a higher risk of T2DM, while the LIS score was not associated with T2DM risk.

Although the cardiovascular benefits of an increased urinary potassium excretion have been suggested, little is known about the potential cardiac association of urinary potassium excretion in patients with chronic kidney disease. In addition, whether the cardiac association of urinary potassium excretion was mediated by serum potassium levels has not been studied yet. We reviewed the data of 1633 patients from a large-scale multicentre prospective Korean study (2011–2016). Spot urinary potassium to creatinine ratio was used as a surrogate for urinary potassium excretion. Cardiac injury was defined as a high-sensitivity troponin T ≥ 14 ng/l. OR and 95 % (CI for cardiac injury were calculated using logistic regression analyses. Of 1633 patients, the mean spot urinary potassium to creatinine ratio was 49·5 (sd 22·6) mmol/g Cr and the overall prevalence of cardiac injury was 33·9 %. Although serum potassium levels were not associated with cardiac injury, per 10 mmol/g Cr increase in the spot urinary potassium to creatinine ratio was associated with decreased odds of cardiac injury: OR 0·917 (95 % CI 0·841, 0·998), P = 0·047) in multivariate logistic regression analysis. In mediation analysis, approximately 6·4 % of the relationship between spot urinary potassium to creatinine ratio and cardiac injury was mediated by serum potassium levels, which was not statistically significant (P = 0·368). Higher urinary potassium excretion was associated with lower odds of cardiac injury, which was not mediated by serum potassium levels.

Research on ethical norms has grown in recent years, but imprecise language has made it unclear when these norms prescribe “what ought to be” and when they merely describe behaviors or perceptions (“what is”). Studies of ethical norms, moreover, tend not to investigate whether participants were influenced by the prescriptive aspect of the norm; the studies primarily demonstrate, rather, that people will mimic the behaviors or perceptions of others, which provides evidence for the already well-substantiated social proof theory. In this review article, we delineate three streams of norms research in business ethics: behavioral, perceptual, and prescriptive. We argue that by properly categorizing norms, and designing studies to investigate when prescriptions, more than mere mimicry, improve ethical outcomes in organizations, researchers can enhance managers’ efforts to promote ethical outcomes in organizations.

This paper examines how the British South Africa Company (BSAC; the Company), the founding administrator of Southern Rhodesia, now Zimbabwe, navigated the creation of a fiscal system of the colony from 1890 to 1922 and how the fiscal system shaped political decisions regarding the colony’s administrative structure. It casts light on the early efforts of the colonial state-making process under the BSAC and how it established its administrative structure. Once occupation was completed, the Company’s ability to finance the cost of governance and administration was the most critical factor facing it. Whereas earlier scholarship has discussed various aspects of Southern Rhodesia’s early economic endeavors and political evolution, this paper demonstrates the significance of the fiscal system in shaping both the economic and political trajectories of the early administration. Through analyzing the Company’s revenue collection and expenditure patterns, the paper reconstructs the contours of shifting notions of what constituted the Company’s commercial and administrative revenue. It argues that the BSAC’s fiscal and budgetary administration approach was gradual, experimental, and sometimes ad hoc, resulting in continuous conflicts between the Company administration and the settlers. The paper relies on a wide range of sources that include the BSAC annual reports, historical manuscripts, Legislative Council debates, newspapers, and other political pamphlets to unpack the tensions between the Company government and white settlers over the fiscal and administrative evolution of the colony.

Termite colony foundation precedes the incipient stage, when the first oviposition cycle takes place, followed by months of reproductive inactivity. The royal couple is supposed to cease oviposition during this period, investing energy to care for the first brood. When a suitable number of alloparents differentiate, egg-laying resumes. Here we followed oviposition dynamics, embryo development and queen/king body changes in laboratory colonies of the major pest species Coptotermes gestroi (Rhinotermitidae) and Cryptotermes brevis (Kalotermitidae) during 9 months. We show that they differ in these oviposition dynamics, as C. gestroi queens displayed an uninterrupted oviposition whereas C. brevis laid a cohort of eggs and ceased oviposition during a 3-month period (lag phase). C. gestroi oviposition dynamic was remarkable and suggests that occurrence of progeny was not a limiting factor, thus queens and kings were able to concomitantly invest energy in reproduction and parental care. These findings contrast those reported for rhinotermitids from temperate areas, and we discuss the likely reasons for such a condition, including endogenous rhythms, avoidance of a high mortality rate of the first progeny and adaptation to the weather conditions of the Neotropical region. Oviposition dynamic in C. brevis resembled those of several termite species, in which the royal couple cease reproduction to care for the first brood. Rearing conditions did not influence oviposition dynamics (egg-laying cycle followed by a lag phase), thus our results on the oviposition of C. gestroi and C. brevis correspond to different reproductive strategies post-foundation adopted by these pest species.

Especially with the Asian financial crisis of 1997–98, Asian countries have advocated a profound reform of the international financial architecture. Their proposals focused on two main axes: a reform of the global financial system, and stronger regional monetary integration in Asia. There are here significant parallels with the ideas of Robert Triffin (1911–1993). Triffin became famous with trenchant analyses of the vulnerabilities of the international monetary system. The Triffin dilemma is still present among international monetary policy-makers, also in Asia. Triffin put forward several proposals for reforming the global monetary system, but he also developed proposals for regional monetary integration. These were very much based on his experience with the European Payments Union, and focused on the creation of a (European) reserve fund and a (European) currency unit. In this paper we focus on Triffin’s proposals for an Asian payments union in the late 1960s, giving special attention to Japan (in Triffin’s time, the biggest Asian economy; moreover, Triffin had an important Japanese network).

During the height of its power over everyday life, between 1968 and 1993, the Cuban Communist Party outlawed virtually all non-state labour and exchange. Since then, however, its continuity in power has increasingly depended on devolution: shifting responsibility for the provision of basic goods and services from failing state enterprises back to the self-employed. The latter now produce the majority of food and basic products; receive most of the national income from tourism, remittances and foreign investment; and generate most new jobs. Nevertheless, they subsist under a subaltern regime of fragile and conditional freedoms. The article adapts James Scott's consideration for the subaltern's ‘hidden transcripts’ and agencies to contemporary Cuba. It analyses the unavoidability of informal and illegal practices for daily subsistence; their naturalisation in society in contrast with their delegitimisation as opportunistic self-enrichment in party-controlled media; and how the self-employed resist such judgements in favour of more conciliatory civic visions.

Among food groups with putative benefits for brain structures, dairy products (DP) have been poorly studied. The sample included participants without dementia from the ancillary brain imaging study of the Three-City cohort who were aged 65+ years, had their DP intake assessed with a FFQ at baseline and underwent an anatomical scan 3 years (n 343) or 9 years (n 195) after completing the dietary survey. The frequencies of consumption of total DP, milk and cheese were not associated with brain structure. Compared with the lowest frequency, the highest frequency of fresh DP (F-DP) consumption (< 0·5 v. > 1·5 times/d) was significantly associated with a lower medial temporal lobe volume (MTLV) (β = −1·09 cm3, 95 % CI − 1·83, −0·36) 9 years later. In this population-based study of older adults, the consumption of F-DP more than 1·5 times/d was associated with a lower MTLV, which is considered an early biomarker of Alzheimer’s disease, 9 years later. This original study should be replicated in different settings before conclusions are drawn.
