Authors: Tamiru Yihalem , Mulugeta Afework , Ayelign Abebe , Jara Dube , Melaku Elyas , Gebremedhin Samson
Published: September 2024

Addis Ababa initiated a universal Home-Grown School Feeding Program (HGSFP) in February 2019 to address hunger and improve the educational outcomes of schoolchildren. This study aimed to document the perceived benefits and challenges of the HGSFP in Addis Ababa, where such information was lacking. In May 2023, a qualitative phenomenological study was conducted to collect data from 20 schools participating in the HGSFP. Data were collected through key informant interviews and focus group discussions (FGDs) involving 98 purposively selected participants. The study encompassed 48 student mothers in 5 FGDs, 20 student interviews, 20 school principals, and 10 experts from the Ministry of Education, Sub-cities, and the School Feeding Agency for in-depth interviews. Data collected in the local language were transcribed, translated into English, and thematically analysed using ATLAS-TI software. The study’s findings unveiled the transformative impact of the HGSFP in Addis Ababa, Ethiopia. It demonstrated remarkable improvements in attendance, concentration, academic performance, reduced dropout rates, financial relief, enhanced behaviour, and a safer learning environment. However, urgent measures are imperative to tackle pressing challenges such as underpaid kitchen workers, operational issues, reduced reading time, rising food costs, limited market access, inadequate infrastructure, and growing dependency. To ensure the enduring sustainability of HGSFP, addressing challenges like workload reduction, kitchen infrastructure enhancement, government guideline implementation, promoting self-reliance, overcoming budget limitations, and addressing school gardening obstacles is vital.

Media Credibility and Voter Penalization of Corrupt Politicians in Latin America
Authors: van Klaveren Carmen , Murshed Syed Mansoob , Papyrakis Elissaios
Published: September 2024

There has been a significant growth of social media as a means to inform oneself about politics. This article explores the consequences of this trend on the credibility audiences attribute to news exposing corrupt politicians and on their willingness to penalize the exposed politicians in elections. The study focuses on ten Latin American cities and employs a randomized control trial using experimental data embedded in a survey. Through this method, credibility and penalization levels are compared between state communications, newspapers, named journalists on social media, and anonymous journalists on social media. The article’s key findings demonstrate that corruption reports published on social media are deemed less credible than those published by state auditors and newspapers. This effect is exacerbated when the source of the report is anonymous. In addition, reports on corruption published on social media by anonymous sources have a negative effect on voter penalization of corrupt politicians.
The Legal Realists on Political Economy
Authors: Priel Dan
Published: September 2024

Alongside the well-known jurisprudential ideas associated with legal realism, some scholars have highlighted the realists’ political-economic ideas. Best known among them has been Morton Horwitz, who has argued that the realists launched an “attack on the legitimacy of the market.” Other scholars challenged this view and argued that there was no significant connection between legal realism and political economic ideas. I offer a corrective to both views. I first consider the work of five legal realists (Karl Llewellyn, Adolf Berle, William O. Douglas, Jerome Frank, and Thurman Arnold) and show that all held views that were well within the political-economic mainstream of their era, which did not challenge the legitimacy of market capitalism but wanted to see markets better regulated. I also show that for many of these realists, there were important connections between their jurisprudential and political-economic ideas. I then turn to some neglected writings of Felix Cohen to show that he too saw a direct link between his legal and economic ideas. However, unlike the other legal realists discussed here, he was a radical critic of market capitalism. I use his political-economic writings for a reconsideration of his better-known jurisprudential works.
Responsible Research: Reflections of Two Business Scholars Doing Mental Health Research During COVID-19
Authors: Zhang Stephen X. , Chen Jiyao
Published: September 2024

This essay reflects the journey of two business scholars, Stephen X. Zhang and Jiyao Chen, who ventured into mental health research during the COVID-19 pandemic. We experienced first-hand how health sciences have operated their publication systems in ways that uphold scientific standing while addressing real-world problems. In doing so, we found the publishing expectations and norms in health and medical sciences to be vastly different from those in management. This essay further discusses aspects such as the preference for evidence over theory, the relationship with basic sciences, diverse evaluation criteria, encouragement of exploration and replication, timeliness, and democratization and inclusivity of scholarship as concrete steps of responsible research.
Denying “The Right to Have Rights”: Europe’s Imposition of Mandates in Greater Syria and the Rise of Islamist Movements
Authors: Thompson Elizabeth F.
Published: September 2024

In 1920, the Syrian Congress at Damascus ratified a democratic constitution that would have been beyond the dreams of activists in the 2011 Arab Spring. Under the leadership of the leading Islamic reformer of the day, Sheikh Rashid Rida, the constitution disestablished Islam as a state religion, guaranteed one-third of parliamentary seats to non-Muslim minorities, and promised autonomy to the majority Christian territory of Mount Lebanon. Unlike the Ottoman constitution that had once reigned in Greater Syria, the Syrian document granted the preponderance of power to parliament, not the monarch. Nonetheless, the British and French colluded in the willful destruction of this nascent democracy. And with League of Nations’ support, they divided the Syrian Arab Kingdom into sectarian mandatory states. By stripping Syrian Arabs of a self-determined political community, Europeans denied them the “right to have rights,” as Hannah Arendt argued. The political backlash against European rule transformed the minority question in Syria into a polarized and violent contest, leading to the sectarian conflicts that overwhelmed Syria, Lebanon, and Palestine in the remainder of the 20th century.
ORIGIN AND AGE OF CARBON IN THE CELLULOSE OF MID-LATITUDE TREE RINGS

Published: September 2024

Cellulose of tree rings is often assumed to be predominantly formed by direct assimilation of CO2 by photosynthesis and consequently can be used to reconstruct past atmospheric 14C concentrations at annual resolution. Yet little is known about the extent and the age of stored carbon from previous years used in addition to the direct assimilation in tree rings. Here, we studied 14C in earlywood and latewood cellulose of four different species (oak, pine, larch and spruce), which are commonly used for radiocarbon calibration and dating. These trees were still growing during the radiocarbon bomb peak period (1958–1972). We compared cellulose 14C measured in tree-ring subdivisions with the atmospheric 14C corresponding to the time of ring formation. We observed that cellulose 14C carried up to about 50% of the atmospheric 14C signal from the previous 1–2 years only in the earlywood of oak, whereas in conifers it was up to 20% in the earlywood and in the case of spruce also in the latewood. The bias in using the full ring of trees growing in a temperate oceanic climate to estimate atmospheric 14C concentration might be minimal considering that earlywood has a low mass contribution and that the variability in atmospheric 14C over a few years is usually less than 3‰.
Correlation between dental microwear analysis and dietary habits of Neanderthal populations in the Iberian Peninsula
Authors: Strimenopoulos Aristeidis , Lozano Marina
Published: September 2024

The dietary habits of Neanderthals are considered an issue of great interest in the literature and have opened an important number of fruitful debates. Indeed, understanding diets can provide important information regarding issues of palaeoenvironmental reconstructions and subsistence strategies. In this respect, dental remains can play a vital role in the conducted efforts to reconstruct the palaeoecological niches securely and accurately since dental microwear analyses have precisely detected dietary patterns of the populations in the past. In this context, the Iberian Peninsula forms an interesting model for examining Neanderthal populations, their subsistence strategies, and adaptive skills. This study aims the examination of already published data in order to provide a holistic approach regarding the dietary habits of H. neanderthalensis populations in the Iberian Peninsula, along with the importance of the utilization of dental microwear analysis in the archaeological record.
Development of an Interdisciplinary Approach to the Radiocarbon Dating of Earth Mortars from Alula Old Town (Saudi Arabia). Integration of Building Archaeology, Mortar Analysis and Radiocarbon Dating
Authors: Gilento Piero , Pesce Giovanni , Vernet Apolline , Pesce Cecilia
Published: September 2024

This paper discusses the approach used to identify the most relevant chronological information on the historic development of the abandoned site of AlUla Old Town, in the northwest of the Kingdom of Saudi Arabia (Western Asia). The approach is based on the use of the radiocarbon method to date earth mortars samples and soil layers used to create the constructive sequence of some buildings and, in turn, the chronological evolution of the site. Eleven samples of organic material (i.e., charcoal and vegetable fibers) were carefully removed from mortar samples and soil levels from six buildings and structures in the northern and southern areas of the town. Buildings and soil layers were chosen for their stratigraphic relevance and conservation conditions, based on an initial archaeological analysis of both, buildings and underground structures. Laboratory-based mortar analysis led to the characterization of the mortar’s inorganic fraction, and to the isolation of the organic material for the radiocarbon dating. Results from the accelerator mass spectrometry (AMS) laboratory provides evidence of a Late Mamluk/Early Ottoman constructive phase (i.e., 15th–17th c. AD) of the Old Town that was only partially known until very recently. Furthermore, the results allowed the identification of an Ottoman phase (i.e., 17th–19th c. AD) during which most of the buildings and structures were rebuilt, and of a Late Ottoman phase (i.e., 19th–20th c. AD) representing the most recent interventions before the end of the Ottoman occupation of the area.

Polycyclic aromatic hydrocarbons (PAHs) are major air pollutants that are ubiquitously produced by the combustion of organic materials, and it is extremely important to identify their pollution sources. In this study, molecular fingerprinting and compound class-specific radiocarbon dating (CCSRA) were performed on PAHs from canal sediments and air samples collected in Kolkata, India’s third largest city (population approximately 16 million), where PAHs pollution has been a serious problem. Average PAH (Σ12-parent PAHs) concentrations in air samples were 65.1 ng m–3 in summer and 70.9 ng m–3 in winter and in canal sediments were 32.7 µg g–1, which are classified as “very high-level” pollution. Molecular fingerprinting using methyl-PAH/PAH (MPAHs/PAHs) ratios and isomer pair ratios with molecular weights of 178, 202, 228, and 276 suggested that wood and coal combustion were the dominant sources of PAHs in the sediment, and that atmospheric PAHs were influenced by oil combustion in addition to them. The fraction of contemporary carbon (ƒC) of sedimentary PAHs (0.056–0.100), together with the extremely low MPAHs/PAHs ratio results, lead to the conclusion that the major source of the high concentration of PAHs in the canals is from coal combustion. On the other hand, the ƒC of atmospheric PAHs (0.272–0.369) was close to the share of biomass fuels in India’s domestic fuel consumption in 2011 (about 35%). Furthermore, the observed ƒC-discrepancy between atmospheric and sedimentary PAHs in the same urban environment was interpreted to give an insight into the loading pathway of PAHs to canal sediments in Kolkata.

Published: September 2024

In 2018, an Ionplus 200 kV MIni-CArbon DAting System (MICADAS) accelerator mass spectrometer (AMS) was installed at the Laboratory of AMS Dating and the Environment, Nanjing University (NJU-AMS Laboratory), China. The NJU-AMS Laboratory is largely devoted to research on radiocarbon dating and 14C analysis in fields of earth, environmental and archaeological sciences. The laboratory has successfully employed various pretreatment methods, including routine pretreatment of tree rings, buried wood and subfossil wood, seeds, charcoal, pollen concentrates, organic matter, and shells. In this study, operational status of the NJU-AMS is presented, and results of radiocarbon measurements made on different sample types are reported. Measurements on international standards, references of known age, and blank samples demonstrate that the NJU-AMS runs stably and has good reproducibility on measurement of single samples. The facility is capable of measuring 14C in samples with the precision and accuracy that meet the requirements for investigating annual 14C changes, history-prehistory age dating, and Late Quaternary stratigraphic chronology research.
How Music and Our Faculty for Music Are Made for Each Other
Authors: PARAKILAS JAMES
Published: September 2024

This study relies on the prevalence of certain structures that largely distinguish the creation and reception of music from that of language – namely, temporal grids, scalar grids, and segments with their repetitions – to construct a model of the human cognitive faculty for music that allows humans to make music the way they do. The study draws on research and thought in philosophy (including phenomenology), linguistics, psychology, and neurology, coupled with musicology, to produce a model of a human capacity to make complex comparisons between ongoing sound sequences and those simultaneously reconstructed from memory by registering the relativities within their flow. This model is then used in a consideration of how the faculty for music interacts with the faculty for language in the experience of song and a consideration of how a similar cognitive capacity for music might be identified in other species.

Published: September 2024

Previous studies have found direct associations between glycaemic index (GI) and glycaemic load (GL) with chronic diseases. However, this evidence has not been consistent in relation to mortality, and most data regarding this association come from high-income and low-carbohydrate-intake populations. The aim of this study was to evaluate the association between the overall GI and dietary GL and all-cause mortality, CVD and breast cancer mortality in Mexico. Participants from the Mexican Teachers’ Cohort (MTC) study in 2006–2008 were followed for a median of 10 years. Overall GI and dietary GL were calculated from a validated FFQ. Deaths were identified by the cross-linkage of MTC participants with two national mortality registries. Cox proportional hazard models were used to estimate the impact of GI and GL on mortality. We identified 1198 deaths. Comparing the lowest and highest quintile, dietary GI and GL appeared to be marginally associated with all-cause mortality; GI, 1·12 (95 % CI: 0·93, 1·35); GL, 1·12 (95 % CI: 0·87, 1·44). Higher GI and GL were associated with increased risk of CVD mortality, GI, 1·30 (95 % CI: 0·82, 2·08); GL, 1·64 (95 % CI: 0·87, 3·07) and with greater risk of breast cancer mortality; GI, 2·13 (95 % CI: 1·12, 4·06); GL, 2·43 (95 % CI: 0·90, 6·59). It is necessary to continue the improvement of carbohydrate quality indicators to better guide consumer choices and to lead the Mexican population to limit excessive intake of low-quality carbohydrate foods.
Associations between the nutritional quality of snacks, overall diet quality and adiposity: findings from a nationally representative study of Australian adolescents

Published: September 2024

The primary aim of this study was to examine the association between snack nutritional quality, overall diet quality and adiposity among Australian adolescents. The secondary aim was to assess the distribution of discretionary foods (i.e. energy-dense and nutrient-poor foods and beverages) and intakes from the five food groups at different levels of snack nutritional quality. Dietary data collected from nationally representative adolescents (12–18 years old) during a 24-h dietary recall in the National Nutrition and Physical Activity Survey were analysed (n 784). Snacks were defined based on participant-identified eating occasions. Snack nutritional quality was assessed using the Nutrient Profiling Scoring Criterion (NPSC), whereas diet quality was evaluated using the Dietary Guideline Index for Children and Adolescents. Adiposity was assessed through BMI Z-score waist circumference and waist:height ratio (WHtR). Higher nutritional quality of snacks, as assessed by the NPSC, has been associated with higher diet quality among both boys and girls (P < 0·001). However, there is no association between snacks nutritional quality with BMI Z-score, waist circumference and WHtR. Among both boys and girls, the consumption of fruits, vegetables and legumes/beans at snacks increased with improvement in snack nutritional quality. Conversely, the consumption of discretionary foods at snack decreased with improvement in snack nutritional quality. In conclusion, improved snack quality was associated with better diet quality in adolescents. However, there was no association between snack nutritional quality and adiposity. Future, snack nutrition quality indices should consider optimum snack characteristics related with adiposity and diet quality.
VOTING PROTOCOLS AS INFORMAL JUDICIAL INSTITUTIONS: THE POLITICS OF ENFORCEABILITY AND STRATEGIC BREACHING
Authors: Rivera León Mauro Arturo
Published: September 2024

Constitutional courts operate under a framework of formal and informal rules. While formal rules have been extensively studied, our understanding of informal rules remains limited. Courts often rely on internal practices, traditions and unwritten customs developed over time, posing a significant challenge due to their hidden nature. Numerous constitutional courts lack detailed voting protocols in their statutes and internal regulations, leaving essential aspects to the court's discretion, such as, inter alia, the voting order, deliberation style, outcome versus issue voting and tie-breaking protocols. By employing a case study of strategic breaching of informal voting protocols in the Mexican Supreme Court, this article highlights the complexity of enforcing informal voting rules given that external actors may be unaware of them, along with other factors. Even when informal rules are broadly known, certain circumstances may diminish the efficacy of informal sanctions addressing their breach. Thus, key judicial players, such as chief justices or judge-rapporteurs, may take advantage of the informal rules of voting protocols to advance their policy preferences.
Old Wine in New Bottles, or Novel Challenges? A Labour History Perspective on Digital Labour
Authors: Akgöz Görkem
Published: September 2024

A growing body of literature is challenging techno-fetishistic perspectives on digital capitalism, as well as claims of the start of a new era characterized by total automation. This article contributes to the ongoing debate on the implications of digital technology for the future of labour by reading Moritz Altenried's The Digital Factory (2022) through the lens of labour history. The use of digital factory and digital Taylorism as integrative tools significantly improves empirical evaluations of different digital labour environments. However, because of their high degree of abstraction, there are a number of limitations when applying these concepts to describe wildly disparate work environments. To illustrate these limits, I use examples from twentieth-century debates on technology and work autonomy, and (1) argue that a labour history perspective warns us against overgeneralizing the effects of technology on labour control and worker autonomy, and (2) broaden the discussion to larger issues of labour control before and during digitalization, incorporating new theoretical questions such as our understanding of classical Taylorism and, by extension, capitalism.
“Be a Miner”: Constructions and Contestations of Masculinity in the British Coalfields, 1975–1983
Authors: Gildart Keith , Curtis Ben , Perchard Andrew , Millar Grace
Published: September 2024

In 1975, the National Coal Board (NCB) produced a short film, “People Will Always Need Coal”, to encourage recruitment into mining. It was extraordinarily attention-grabbing, presenting miners as cosmopolitan playboys. It defined the industry in hyper-masculine terms, encouraging would-be recruits to “be a miner”. This article uses the film as a starting point for a discussion of the complex interactions between the material realities of masculinity, class, and culture within Britain's coalfields in the period 1975–1983. A critical reading of the film is complemented by archival research and oral testimony drawn from interviews with 96 former miners and their families. At a time when the industry was positioning itself as an employer with a long-term future, mining was presented on screen as a modern masculine occupation that was far removed from the dominant imagery of coal for much of the twentieth century. The National Union of Mineworkers’ (NUM) victories in the strikes of 1972 and 1974, the drafting of a Government Plan for Coal, and rising living standards, created a short period of optimism before the cataclysmic closures of the 1980s and 1990s. This was a time when masculinity in the coalfields was being reproduced, modified, contested, and subverted. The years 1975–1983 offer valuable insight into such masculinity and the ways it was mediated and challenged through work, the domestic sphere, leisure, and popular culture.
Unimaginable Community: Watchwords and Frelimo's Abandoned Nationalism in Independence-Era Mozambique
Authors: Allina Eric
Published: September 2024

During its decade-long war (1964–74) against Portuguese colonialism, Frelimo developed a language to express the style in which it imagined the nation. On taking power in 1975, Frelimo used this language — its watchwords — to signal the shared identity it aimed to instill within Mozambique. Frelimo asked Mozambicans to live in the future tense: to turn away from familiar idioms of belonging and embrace a sense of self and other untethered to past or present. The misalignment between this vision and its reception is most evident at local levels of administrative action, where people at lower rungs of the state received Frelimo's watchwords and creatively applied them, transforming ideas into practices. Many Mozambicans were unable or unwilling to accept Frelimo's vision, and as civil war engulfed more of the country in the early 1980s, Frelimo abandoned this nationalism, exchanging it for an idea of national community people could more easily imagine.
Neo-Imperial Cold War? Biafra's Franco-African Arms Triangle
Authors: Wyss Marco
Published: September 2024

During the Nigerian Civil War, France became the main supplier of military assistance to the secessionist Biafra. In a neo-imperial pursuit to weaken the potential regional hegemon Nigeria, it secretly provided arms and ammunition to the Biafrans in collusion with Côte d'Ivoire and Gabon. Yet the driving force behind this Franco-African arms triangle was not the Elysée, but the Ivorian president Félix Houphouët-Boigny. Newly unearthed documentary evidence from French archives enables this article to break new historiographical ground: firstly, to show the Elysée's sheer reluctance to militarily assist Biafra and lack of a coherent policy in doing so; secondly, to confirm Houphouët-Boigny as the “mastermind” behind the arming of Biafra, as well as to identify his Cold War motivations; thirdly, to uncover Gabonese president Omar Bongo's increasing agency and influence in the scheme; fourthly, to demonstrate that it was the Ivorian and Gabonese presidents who transformed the arms triangle into a square by bringing the Rhodesians and, especially, the South Africans in; and, finally, to retrace the emergence and functioning of the “African-French” military assistance to Biafra at the policy level not only from Paris's, but also Abidjan's and Libreville's perspectives.
Two Jubilees of Warsaw Lutherans, 1881 and 1931
Authors: ŁUPIENKO ALEKSANDER
Published: September 2024

The Lutheran minority in Warsaw celebrated the 100th anniversary of its magnificent classicist church in 1881, under Russian rule, when the parish was predominantly culturally German; and the 150th anniversary in 1931/2, during the Second Polish Republic, when the clergy were to a large extent Polish-speaking. This article compares these two jubilees to show acts of commemoration as a tool, steering religious bonds and social identification, whether or not consciously. It highlights the social, ‘terrestrial’ aspects of the functioning of confessional minorities, showing how the community was constantly reinvented through common memory.
Contrasting patterns of decadal stability for shallow water sponge boulder assemblages and subtidal rocky cliffs at Lough Hyne, Ireland
Authors: Bell James J. , Micaroni Valerio , Wood Gabriela , Hughes Mack , Donnelly Alison , McAllen Rob
Published: September 2024

Lough Hyne (LH) Marine Nature Reserve in Ireland is a globally recognised biodiversity hotspot that hosts mesophotic-like communities in shallow water, however, major changes have occurred to most of the rocky cliff (>6 m) communities in one or more events between 2010 and 2015. To provide insights into these changes, we compared the sponge assemblage composition on the undersides of different sized, shallow (<1 m) subtidal boulders between 2000 and 2022 at two sites in LH. We also measured sponge species richness at seven sites in 2018. We found that unlike earlier reports from the deeper subtidal reef sponge assemblages, there was no evidence for changes in sponge assemblage composition on the undersides of boulders at either site. We also found high levels of sponge species richness at all seven sites sampled in 2018. We did find differences in sponge assemblages between sites and for different boulder sizes, which we propose is a result of site-specific environmental conditions and disturbance and size–area relationships. Since we found no changes in the shallow subtidal sponge assemblages between 2000 and 2022, our results support the hypothesis that changes to the deeper subtidal sponge assemblages at LH are driven by local processes associated with deeper water in LH, potentially related to the seasonal oxythermocline that forms within LH. Given the national and global importance of LH, understanding the drivers of change is critical to determine if management actions can prevent any future alterations to the LH sponge assemblages and support wider mesophotic community management.

Migrant Voices in Multilingual London, 1560–1600
Authors: Gallagher John
Published: September 2024

Early modern London was multilingual, and early modern urban life was shaped by linguistic diversity. This article draws on the multilingual archives of Elizabethan London's ‘stranger churches’ – Protestant congregations which catered to the needs of French-, Dutch- and Italian-speaking migrants (among others) – to explore how linguistic diversity shaped social relations. These sources offer insights into the everyday multilingualism of the early modern city. They demonstrate London's migrant communities’ intense interest in what people said and why, and show how different languages and their speakers interacted on the streets and in the spaces of later sixteenth-century London. By charting how linguistic diversity was part of the lives of ordinary Londoners in this period, including close examination of incidents of multilingual insult, slander, and conflict, this article argues that the civic and religious authorities relied on the stranger churches’ abilities to carry out surveillance of speech in languages other than English, and that urban social relations and urban spaces were shaped by multilingualism. It ends by arguing that linguistic diversity played an essential but understudied role in the social history of early modern cities.
Promoting Well-being through History Teaching
Authors: Stack David
Published: September 2024

This article explores the potential for the greater infusion of well-being concerns into the teaching of history in UK HEIs. Drawing upon results from a survey of over 100 current undergraduates in one UK History department, alongside a scoping study of well-being provision provided by history departments or their equivalent in about ninety UK HEIs, this article considers ways in which well-being can be promoted through the teaching and learning strategies of historians. The article discusses the meaning of the term ‘well-being’ and asks why historians have sometimes been reluctant participants in the ‘eudaemonic turn’. The negativity bias of history as an endeavour, and the potential for understanding the past to enhance or diminish an individual's sense of well-being is discussed, as is the value of historicising the concept of well-being itself. The case for integrating well-being as a key element in the degree-level study of history is made, and the article concludes by urging all HEI history practitioners to consider the value of curricular infusion and mapping the design and delivery of their modules onto the New Economics Foundation's ‘five ways to well-being’.
Defining music demonstration lessons: a unique performance-based lesson type improving teachers’ instructional skills in Chinese mainland education
Authors: Zhang Le-Xuan , Leung Bo-Wah
Published: September 2024

Teaching is a highly complex act, and learning to teach in an educational era that combines both teacher-centred and student-centred approaches presents additional challenges. Conducting demonstration lessons (DL) is one of the methods aimed at enhancing teachers’ instructional skills. This study examines the features and functions of this unique type of lesson from the perspective of music demonstration teachers in Guangdong, China. Through observation and interviews, the findings not only reveal the prevalence of DLs as performance-based lessons in Chinese teachers’ professional lives but also explore their distinctions from regular school teaching and their potential for improving teachers’ pedagogical abilities. Concerns and issues related to this type of lesson, along with possible solutions, are also discussed to provide recommendations for incorporating DLs into teacher training programmes in higher education institutions.
INFERENCE IN MILDLY EXPLOSIVE AUTOREGRESSIONS UNDER UNCONDITIONAL HETEROSKEDASTICITY
Authors: Yu Xuewen , Kejriwal Mohitosh
Published: September 2024

Mildly explosive autoregressions have been extensively employed in recent theoretical and applied econometric work to model the phenomenon of asset market bubbles. An important issue in this context concerns the construction of confidence intervals for the autoregressive parameter that represents the degree of explosiveness. Existing studies rely on intervals that are justified only under conditional homoskedasticity/heteroskedasticity. This paper studies the problem of constructing asymptotically valid confidence intervals in a mildly explosive autoregression where the innovations are allowed to be unconditionally heteroskedastic. The assumed variance process is general and can accommodate both deterministic and stochastic volatility specifications commonly adopted in the literature. Within this framework, we show that the standard heteroskedasticity- and autocorrelation-consistent estimate of the long-run variance converges in distribution to a nonstandard random variable that depends on nuisance parameters. Notwithstanding this result, the corresponding t-statistic is shown to still possess a standard normal limit distribution. To improve the quality of inference in small samples, we propose a dependent wild bootstrap-t procedure and establish its asymptotic validity under relatively weak conditions. Monte Carlo simulations demonstrate that our recommended approach performs favorably in finite samples relative to existing methods across a wide range of volatility specifications. Applications to international stock price indices and U.S. house prices illustrate the relevance of the advocated method in practice.

Published: September 2024

The crystal structure of perfluorononanoic acid (PFNA) was solved via parallel tempering using synchrotron powder diffraction data obtained from the Brockhouse X-ray Diffraction and Scattering (BXDS) Wiggler Lower Energy (WLE) beamline at the Canadian Light Source. PFNA crystallizes in monoclinic space group P21/c (#14) with lattice parameters a = 26.172(1) Å, b = 5.6345(2) Å, c = 10.9501(4) Å, and β = 98.752(2)°. The crystal structure is composed of dimers, with pairs of PFNA molecules connected by hydrogen bonds via the carboxylic acid functional groups. The Rietveld-refined structure was compared to a density functional theory-optimized structure, and the root-mean-square Cartesian difference was larger than normally observed for correct powder structures. The powder data likely exhibited evidence of disorder which was not successfully modeled.

The aim was to explore whether the time-lapse imaging system can help day-3 single cleavage embryo transfer to obtain comparative clinical outcomes to day-4 or 5. The data of 1237 patients who underwent single embryo transfer from January 1, 2018, to September 30, 2020, in our reproductive medicine centre were retrospectively analysed. They were divided into the day-3 single cleavage-stage embryo transfer (SCT) group (n = 357), day-4 single morula transfer (SMT) group (n = 129) and day-5 single blastocyst transfer (SBT) group (n = 751) according to the different embryo transfer stage. The clinical and perinatal outcomes of the three groups were analysed and compared. The clinical pregnancy rates of the patients in the day-3 SCT group, day-4 SMT group and day-5 SBT group were 68.07, 70.54 and 72.04%, respectively. The live birth rates were 56.86, 61.24 and 60.99%, respectively. The monozygotic twin (MZT) rate in the day-3 SCT group was significantly lower than that in the day-5 SBT group (P = 0.049). Regarding perinatal outcomes, only the secondary sex ratio had a significant difference (P < 0.05). After age stratification, no improvement was found in the pregnancy outcomes of patients >35 years of age receiving blastocyst transfer. Our findings suggest that for patients with multiple high-quality embryos on day-3, prolonging the culture time can improve the pregnancy outcome to some extent, but it will bring risks. For centres that have established morphodynamic models, day-3 SCT can also achieve an ideal pregnancy outcome and reduce the rate of monozygotic twins and sex ratio.

We examine how media reports influenced trading volumes and order imbalances on the Sydney Stock Exchange (SSX) from 1901 to 1950, focusing on wool market reports as a substitute for broader financial advice in the absence of a specialised investment press. Given wool's status as Australia's primary export and its integration with various sectors, we construct a weekly media sentiment index based on news about wool sales and auctions from the Sydney Morning Herald. Our findings reveal that positive news about the wool market correlates with increased trading volumes and reduced order imbalances on the SSX. This relationship persisted during significant events such as the UK government's wool purchase plans, the 1929 Wall Street Crash, World War II-related trading restrictions, and the short selling ban.
Coping patterns associations with cognitive function in older adults

Published: September 2024

Objective:

Cognitive function may contribute to variability in older adults’ ability to cope with chronic stress; however, limited research has evaluated this relationship. This study investigated the relationship between theoretically derived coping domains and cognitive function in 165 middle-to-older adults during the Omicron stage of COVID-19.

Method:

Participants completed a clinical interview and self-report measures of health. The National Alzheimer’s Coordinating Center Uniform Data Set neuropsychological battery was used to evaluate memory, language, executive function/speed, and working memory. Structural equation modeling evaluated the underlying factor structure of the Brief COPE adapted for COVID-19.

Results:

The data supported the proposed second-order Approach factor comprised of Problem-Solving and Emotion Regulation (ER) strategies and a first-order Avoidance factor. Higher Avoidance was associated with greater depression symptoms, lower income and worse memory, executive function, working memory, and verbal fluency performance. Higher Problem-Solving was associated with better verbal fluency performance. ER strategies were not significantly associated with cognitive function. The use of Problem-Solving was not associated with less Avoidance. Greater use of Problem-Solving, ER, and Avoidance were all associated with higher levels of stress. Post-hoc analyses found that higher Acceptance was the only coping strategy associated with less stress.

Conclusions:

These findings demonstrate that older adults with worse cognitive function were more likely to use Avoidance during the pandemic, which could result in prolonged stress and adverse health consequences. Future research is warranted to investigate whether acceptance-based interventions reduce the avoidance and impact of stress on health in vulnerable older adults.

Published: September 2024

Objective:

Normal aging often leads to cognitive decline, and oldest old people, over 80 years old, have a 15% risk of developing neurodegenerative diseases. Therefore, it is important to have appropriate tools to assess cognitive function in old age. The study aimed to provide new norms for neuropsychological tests used to evaluate the cognitive abilities in people aged 80 years and older in France, focusing on the impact of education and gender differences.

Method:

107 healthy participants with an average age of 85.2 years, with no neurological history or major cognitive deficits were included. A comprehensive neuropsychological assessment was performed, covering several cognitive functions such as memory, visuospatial abilities, executive functions, attention, processing speed, and praxis.

Results:

Individuals with lower levels of education performed poorly on some tests and took longer to complete. Gender differences were observed, with women outperforming men in verbal episodic memory, while men showed better performance in visuoconstructive tasks. The participants showed lower performance in verbal episodic memory compared to norms established in previous French studies. In relation to executive functions, participants were slower to perform complex tasks than participants in previous studies.

Conclusion:

This study provides cognitive norms specifically adapted to the oldest old population, which differ from established norms for younger aging adults. It highlights the importance of including these norms in future clinical and scientific investigations. The findings underscore the importance of education on cognitive abilities and emphasize the need to consider gender differences when assessing cognitive functions in aging populations.
SPECTRAL CLUSTERING AND LONG TIMESERIES CLASSIFICATION
Authors: SUKHORUKOVA NADEZDA , WILLARD-TURTON JAMES , GARWOLI GEORGINA , MORGAN CLAIRE , ROKEY ALINA
Published: September 2024

Clustering is a method of allocating data points in various groups, known as clusters, based on similarity. The notion of expressing similarity mathematically and then maximizing it (minimize dissimilarity) can be formulated as an optimization problem. Spectral clustering is an example of such an approach to clustering, and it has been successfully applied to visualization of clustering and mapping of points into clusters in two and three dimensions. Higher dimension problems remained untouched due to complexity and, most importantly, lack of understanding what “similarity” means in higher dimensions. In this paper, we apply spectral clustering to long timeseries EEG (electroencephalogram) data. We developed several models, based on different similarity functions and different approaches for spectral clustering itself. The results of the numerical experiment demonstrate that the created models are accurate and can be used for timeseries classification.
South Africa’s Haymarket: the Knights of Labor and political violence in the United States and South Africa, 1886–1892
Authors: Parfitt Steven
Published: September 2024

This article compares and connects two episodes of political violence in the late nineteenth century: the Haymarket Affair in Chicago in 1886 and the bombing of the offices of the De Beers Company, chaired by Cecil Rhodes, at Kimberley on the South African diamond fields in 1891. These episodes were connected by the existence in both countries of an American and then global movement, the Knights of Labor/Labour. The Knights’ American history was shaped by Haymarket. Their South African history was radically altered by the De Beers explosion, which both the Knights and their enemies interpreted through the prism of Haymarket. They drew lessons from it that determined their own conduct and may have contributed to the demise of the South African Knights less than two years later. This article charts those connections and the context to the De Beers explosion, the trial that followed, and the lessons that South African Knights drew from the experiences of their American brothers and sisters.
Investigating the IGF axis as a pathway for intergenerational effects

Published: September 2024

Early nutritional and growth experiences can impact development, metabolic function, and reproductive outcomes in adulthood, influencing health trajectories in the next generation. The insulin-like growth factor (IGF) axis regulates growth, metabolism, and energetic investment, but whether it plays a role in the pathway linking maternal experience with offspring prenatal development is unclear. To test this, we investigated patterns of maternal developmental weight gain (a proxy of early nutrition), young adult energy stores, age, and parity as predictors of biomarkers of the pregnancy IGF axis (n = 36) using data from the Cebu Longitudinal Health and Nutrition Survey in Metro Cebu, Philippines. We analyzed maternal conditional weight measures at 2, 8, and 22 years of age and leptin at age 22 (a marker of body fat/energy stores) in relation to free IGF-1 and IGFBP-3 in mid/late pregnancy (mean age = 27). Maternal IGF axis measures were also assessed as predictors of offspring fetal growth. Maternal age, parity, and age 22 leptin were associated with pregnancy free IGF-1, offspring birth weight, and offspring skinfold thickness. We find that free IGF-1 levels in pregnancy are more closely related to nutritional status in early adulthood than to preadult developmental nutrition and demonstrate significant effects of young adult leptin on offspring fetal fat mass deposition. We suggest that the previously documented finding that maternal developmental nutrition predicts offspring birth size likely operates through pathways other than the maternal IGF axis, which reflects more recent energy status.
