This is a review article of a three-volume book in Persian by Ali Akbar Tashakori on the social history of Yazdi Zoroastrians in medieval and modern times.1 The work goes beyond the history of the Yazdi community, encompassing the broader history of Iranian Zoroastrians. Despite certain novelties, the volumes largely rely on a conventional reconstruction of the history of Iranian Zoroastrians in the second millennium CE. The foundational elements of this reconstruction include the gradual Islamization of Iran and the subsequent “retreat” of Zoroastrians to the “marginal” regions of Yazd and Kerman, the challenging conditions faced by Zoroastrians in medieval and early modern times, the beginning of Iranian Zoroastrians’ social and intellectual “emancipation” in the nineteenth century with Parsi assistance, the community's increasing political and economic influence in the late Qajar and early Pahlavi eras, and the Pahlavis’ exceptional role in elevating the status of Zoroastrians within wider Iranian society. Tashakori's extensive reliance on these narratives offers an opportunity to not only review his own new interpretations, but also to reassess these long-standing assumptions. Additionally, the article highlights neglected primary sources pertaining to the Yazdi community.
Against the background of post-Cold War trade and media liberalization, this article examines how young women living in Yaoundé, Cameroon, share digital images of their crafted styles via WhatsApp. Such sharing is an act of influence usually aimed at building the woman’s name as a digital ‘fashionista’, in that it constitutes a virtual potential for persuading others to copy one’s style. When this potential is actualized among women of status and rank, young women can fashion relations of matronage, opening up avenues of upward social mobility. To reach out to women of status and rank, young women circulate images of their styles to mobilize digital follower networks of peers, kin and strangers, drawing on their skills, status and knowledge. This mobilization in turn relies on the actual and potential benefits that sharing a fashionista image can bring to the follower. Thus, I argue, interdependencies between stylish leaders and their followers are key to making and maintaining a name as a digital fashionista. This article contributes to the literature on fashion and social mobility in West Africa by showing how the circulation of digital images over social media networks generates potentialities for young women living in Yaoundé to fashion matronage relations and social mobility. More broadly, the framing of followers as a form of wealth-in-people provides a critique of the neoliberal market valuation of social media influencers, illuminating alternative regimes of valuation that inform digital influencer economies.
Verbal fluency tests are quick and easy to administer neuropsychological measures and are regularly used in neuropsychological assessment. Additionally, phonological fluency is a widely used paradigm that is sensitive to cognitive impairment. This paper offers normative data of phonological verbal fluency (letters P, M, R) for Spanish middle- and older-aged adults, considering sociodemographic factors, and different measures such as the total number of words, errors (perseveration and intrusions), and 15 sec-segmented scores.
Method:
A total of 1165 cognitively unimpaired participants aged between 50 and 89 years old, participated in the study. Data for P were obtained for all participants. Letters M and R were also administered to a subsample of participants (852) aged 60 to 89 years. In addition, errors and words produced every 15 seconds were collected in the subsample. To verify the effect of sociodemographic variables, linear regression was used. Adjustments were calculated for variables that explained at least 5% of the variance (R2 ≥ .05).
Results:
Means and standard deviations by age, scaled scores, and percentiles for all tests across different measures are shown. No determination coefficients equal to or greater than .05 were found for sex or age. The need to establish adjustments for the educational level was only found in some of the measures.
Conclusions:
The current norms provide clinically useful data to evaluate Spanish-speaking natives from Spain aged from 50 to 89 years. Specific patterns of cognitive impairment can be analyzed using these normative data and may be important in neuropsychological assessment.
Plutarch’s Table Talk asserts the ‘friend-making’ (φιλοποιός) character of the symposium seemingly unproblematically (612D, 621C). Yet it is not entirely clear how readers are to understand the dynamics of social variety in the work, or how its presentation of friendship relates to Plutarch’s formal pronouncements elsewhere on the subject. This article explores connections between Table Talk and aspects of On Having Many Friends and How to Tell a Flatterer from a Friend. It also considers some ideas around poikilia in Plutarch in connection to discussions of complexity and simplicity in Table Talk, as a window onto the work’s presentation of amicable variety. I argue that social variety is often the implicit target in discussions of party pragmatics and gastronomic variety. Unlike the moral essays, Table Talk ultimately endorses a broad conceptualization of friendship’s and variety’s value, inviting readers to rethink Plutarchan ideas for the sympotic context.
This article is part of the collaborative research project Populist Publics. Housed at Carleton University (www.carleton.ca/populistpublics), it applies a data-driven analysis of online hate networks to trace how false framings of the historical past, what we call historical misinformation, circulates across platforms, shaping the politics of the center alongside the fringes. We cull large datasets from social media platforms and run them through a variety of different programs to help visualize how harmful speech and civilizational rhetoric about race, ethnicity, immigration, multiculturalism, gender equality, and LGBTQ+ rights are circulated by far-right groups across borders, noting specifically when and how they are taken up in the mainstream as legitimate discourse. Our interest is in how the distortion of the historical record is used to build alternative collective memories of the past so as to undermine minority rights and cultures in the present. We began with a basic question: To what extent is this actually new? As much as the atomized publics of our current day create ideal conditions for radical ideas to fester and circulate, it was obvious to us that we needed to look for linkages across time, drawing on interdisciplinary methods from the fields of history, media and communication, and data science to identify the tactics, strategies, and repertoires among such groups and individuals. By analyzing German-Canadian relations in particular, what follows is a first attempt to piece together some of these connections, with a focus on far-right hate groups—homegrown and imported—in the settler colonial project that is today's Canada.
The small finds discovered during the 1948–1951 excavations by Katherine M. Kenyon and John B. Ward-Perkins at Sabratha were scattered after the 1950s and have taken some time to be re-assembled. The following report on the small objects includes material in silver, copper alloy, iron, lead, glass, semiprecious stones, clay and stone, with a separate report on the substantial bone artefact assemblage. As well as providing the basic data on the objects, some of which are unique to Roman Libya, efforts have been made to put them into their Empire-wide context.
Field experiment to assess the impact of radiation, temperature and foliar N application on rice was conducted. The treatments comprised of four sunlight levels, [control, 50% intensity during start to maximum tillering (R15–45), maximum tillering to booting (R46–75) and panicle emergence to maturity (R76–105) corresponding to 15–45, 46–75 and 76–105 days after transplanting] and 5 levels of foliar nitrogen [control, spray of 3% urea solution in water before (NB), midway (NM), afterwards (NA) and midway + afterwards (NMA) reduction in sunlight]. Results showed that leaf chlorophyll had an inverse relationship with radiation intensity. The R46–75 significantly reduced effective tillers (13.1–16.4%), R46–75 and R76–105 reduced grains/panicle (7.15–12.5%) as compared to control. NB produced significantly higher effective tillers (21.9–24.7%) and grains/panicle (12.2–12.9%) as compared to control. The reduction in sunlight and application of foliar nitrogen increased the minimum cooking time and decreased elongation ratio. Averaged over locations, R15–45, R46–75 and R76–105 decreased the yield significantly as compared to control by 9.29–11.3, 14.4–16.3 and 8.17–10.6%, respectively. The NB significantly increased grain yield as compared to control by 10.3% (Ludhiana) and 9.45% (Hoshiarpur). A decrease in maximum temperature (Tmax) by 2.85–5.70% (1–2°C) of 35.1°C, at 1416 μmol/m2/s of photosynthetically active radiation (PAR) increased rice productivity by 10.6–21.0%, while a similar decrease in PAR by 2.85–5.70% at a Tmax of 35.1°C, decreased the productivity by 2.05–4.10%. So, decrease in Tmax due to cloudy weather might have a positive influence while negative impact of deficit radiation may be mitigated by foliar application of 3% urea prior to/during the cloudy weather.
The history of the human–technology relation points to binary (positive and negative) evaluations of technology’s role. One reason for this binary is the limited view of technology in terms of physical and tangible devices. Another is an extreme global view of the relationship, which neglects global diversity. However, technology includes non-physical devices such as speech. Moreover, people hold different intellectual, historical and philological assumptions as the bases for their rule over technology. This article emphasizes the importance of language and global diversity as crucial dimensions of the human–technology relation. It is through language that humans are able to rule over technology, rather than being dominated by it. Taking language as a focal point, I expose the neglect of pre-literate orality as a way of engaging with technology and I espouse an orality perspective on our rule over technology. This perspective foregrounds human mindfulness as a basis for oral engagement with technology. It is developed based on analysis of historical data on oral language use by pre-literate Akan people of Ghana to rule over the musket. The article characterizes technology overrule according to a four-stage process: image recognition, technology reduction, technology reposition and image reproduction.
Depending on whether we are somewhat tolerant of nearby error-possibilities or not, the safety condition on knowledge is open to a strong reading and a weak reading. In this paper, it is argued that induction and conjunction introduction constitute two horns of a dilemma for the safety account of knowledge. If we opt for the strong reading, then the safety account fails to account for inductive knowledge. In contrast, if we opt for the weak reading, then the safety account fails to accommodate knowledge obtained via the method of conjunction introduction.
In this paper, a new over-constrained parallel driving mechanism (PDM) with planar sub-closed chains is proposed. First, the number of over-constraints on the PDM is calculated. Then, an analysis is conducted as to the kinematics of the hybrid manipulator, including positions, velocities, and accelerations of all bodies. Furthermore, the Newton–Euler approach is taken to deduce the kinematic formula of each link and the formula of inertial force at the center of mass. However, it remains difficult to solve the equation since the number of equations is smaller than that of unknown variables. To solve this problem, the screw theory is applied in the present study to analyze the cause of over-constraints, with the link’s elastic deformation introduced as the supplement of deformation compatibility equations. Moreover, the actuation forces and constrained forces/moments are calculated simultaneously. Finally, the dynamic model is verified through simulation and experimentation. The proposed modeling approach provides a fundamental basis for the structural optimization and friction force computation of the over-constrained PDM.
Survey evidence tells us that stock prices reflect the risks investors associate with long-run technological change. However, there is a shortage of models that can rationalize long-run risks. Unlike the previous literature assuming a fixed number of products, our model allows for new product varieties that appear in the form of new firms which face entry costs and delay in the entry process. The fixed variety model has a significant limitation in translating macroeconomic volatility into asset return volatility. Our model with growing varieties induces endogenous low-frequency fluctuations in productivity driving large, persistent variations in consumption growth and asset prices. It also changes the valuation of assets through the increase in the volatility of the pricing kernel (with a positive long-run component) and leads to higher excess returns. Our model is motivated by a simple recursively identified VAR model containing quarterly US data 1992Q3-2018Q4 with the following list of variables: total factor productivity, output, a measure of firm entry, and the excess return on stocks.
Up to 90% of adults with untreated atrial septal defect will be symptomatic by 4th decade, and 30-49% will develop heart failure. 8–10% of these patients have pulmonary arterial hypertension with a female predominance regardless of age. We aimed to demonstrate that fenestrated closure can be safely performed in patients with decompensated heart failure and atrial septal defect-associated pulmonary arterial hypertension with improved outcome.
Methods:
Transcatheter fenestrated atrial septal defect closures (Occlutech GmbH, Jena, Germany) were performed on a compassionate-use basis in 5 consecutive adult patients with atrial septal defect-associated pulmonary arterial hypertension and severe heart failure with prohibitive surgical mortality risks. Change in systemic oxygen saturation, 6-minute walk test, NYHA class, echocardiographic and haemodynamic parameters were used as parameters of outcome.
Results:
All patients were female, mean age 48.8 ± 13.5 years, followed up for a median of 29 months (max 64 months). Significant improvements observed in the 6-minute walk test, and oxygen saturation comparing day 0 time point to all other follow-up time points data (B = 1.32, SE = 0.28, t (22.7) = -4.77, p = 0.0001); and in the haemodynamic data (including pulmonary vascular resistance and pulmonary pressure) (B = –0.60, SE = 0.22, t (40.2) = 2.74, p = .009). All patients showed improved right ventricular size and function along with NYHA class. There were no procedure-related complications.
Conclusion:
Fenestrated atrial septal defect closure is feasible in adults with decompensated heart failure and atrial septal defect-associated pulmonary arterial hypertension. It results in sustained haemodynamic and functional improvement
We compute the flow induced by the steady translation of a rigid sphere along the axis of a large cylindrical container filled with a low-viscosity fluid set in rigid-body rotation, the sphere being constrained to spin at the same rate as the undisturbed fluid. The parameter range covered by the simulations is similar to that explored experimentally by Maxworthy (J. Fluid Mech., vol. 40, 1970, pp. 453–479). We describe the salient features of the flow, especially the internal characteristics of the Taylor columns that form ahead of and behind the body and the inertial wave pattern, and determine the drag and torque acting on the sphere. Torque variations are found to obey two markedly different laws under rapid- and slow-rotation conditions. The corresponding scaling laws are predicted by examining the dominant balances governing the axial vorticity distribution in the body vicinity. Results for the drag agree well with the semi-empirical law proposed for inertialess regimes by Tanzosh & Stone (J. Fluid Mech., vol. 275, 1994, pp. 225–256). This law is found to apply even in regimes where inertial effects are large, provided that rotation effects are also large enough. Influence of axial confinement is shown to increase dramatically the drag in rapidly rotating configurations, and the container length has to be approximately a thousand times larger than the sphere for this influence to become negligibly small. The reported simulations establish that this confinement effect is at the origin of the long-standing discrepancy existing between Maxworthy's results and theoretical predictions.
Forensic entomology is an important component of criminal investigations, providing information surrounding a death using region-specific data on the local necrophagous community. To understand the community within the Metro Vancouver region of British Columbia, Canada, a field study monitored the abundance and diversity of necrophagous Calliphoridae (Diptera) over a nine-month period in distinct terrestrial environments. Baited bottle traps (n = 9) were deployed weekly for 12-hour intervals in three different environments. Species, sex, and gravidity of collected specimens were determined. Bivariate analyses revealed significant relationships between species, geographic location, and month of collection, suggesting that Calliphoridae species composition is influenced by habitat type and seasonal shifts in temperature. Sex ratios and reproductive ranges of Calliphoridae differed among the habitats sampled.
