In the course of the project ‘Pottery Production and Distribution of Bronze Age Settlements of Mycenaean Greece and the Aegean’ in 1996, Mycenaean pottery from Boeotia in the Archaeological Museum of Thebes was sampled with a view to investigation by neutron activation analysis (NAA). The NAA results were published and analysed in 2002. Ongoing work with new samples and re-evaluation of pre-existing ones, in both cases deriving from several sites of the Mycenaean world, resulted in the reappraisal of the NAA results concerning the Theban material. The present work aims at the archaeological assessment of the sampled material (152 samples from 148 examples) organised into three sections according to their exact findspot: (a) the chamber tomb cemeteries at Agia Anna area (Kolonaki and Mikro Kolonaki hills) and at Ismenion Hill; (b) the House of Kadmos; and (c) habitation areas at the lower south-east and north-west part of Kadmeia Hill. This classification corresponds roughly to the chronology of the examples dated to Middle Helladic and Late Helladic II to Late Helladic IIIC Late. The bulk of the pottery sampled is Mycenaean. A few examples of Handmade Burnished Pottery are included as well as four fragments of rooftiles, an uninscribed fragment of a Linear B tablet and a clay lump intended for a tablet. Twenty-one chemical groups/subgroups/pairs have been identified. The groups assigned to Boeotia comprise numerous examples excavated mainly at the habitation areas and dated to the subphase Late Helladic IIIB2 Late. Imports from the Peloponnese, Euboea and Crete, as well as one from Corfu, have been recognised, as have pieces of unknown provenance and loners. In conclusion, five chemical groups of pottery (TheA, TanA, TheB, ThBC, TheF) are associated with varying degrees of certainty with Boeotian pottery production. Imports came mainly from the north-eastern Peloponnese in Early Mycenaean times and from Euboea in the late palatial and post-palatial periods.
The present study generates information related to the molecular divergence between turcicum leaf blight (TLB)-resistant and -susceptible lines. During molecular diversity studies, a total of 212 alleles were detected at 75 marker loci and ranged from two to five with an average of 2.83 alleles per locus. A direct correlation for the number of alleles and polymorphism information content (PIC) values was ascertained. For instance, marker phi123 produced high number of alleles (5) with PIC values of 0.77. Using the DARwin 6.0 programme, the UPGMA dendrogram grouped 40 maize inbreds into two distinct clusters, cluster-I (36 inbreds) and cluster-II (4 inbreds). Cluster-I contained two subclusters; the first subcluster contained 28 inbreds and the second subcluster contained eight inbreds whereas cluster-II contained four inbreds. This major cluster-II was further classified into two subclusters which contained two inbreds each. Most of the inbred lines except V-25 from cluster-II were highly resistant to TLB disease. These inbred lines can be used in crossing programmes to develop TLB-resistant hybrids by using divergent parents. In this study, allelic diversity and PIC values indicated a good efficiency of markers for studying the polymorphism level available in studied inbred lines. High level of diversity among the inbreds detected with simple sequence repeat markers indicated their suitability for the further breeding programme.
Evolution has shown that legged locomotion is most adequate for tasks requiring versatile movement on land, allowing animals to traverse a wide variety of environments ranging from natural terrain to artificial, man-made landscapes with great ease. By employing well-designed control schemes, this ability could be replicated for legged robots, enabling them to be used in critical situations that still pose great danger to human integrity, such as search and rescue missions, inspection of hazardous areas, and even space exploration. This work characterizes the quadruped robot and contact dynamics that will compose our in-house simulator to be used for prototyping locomotion control schemes applied to quadruped robots. The proposed simulator computes the robot dynamics using the Recursive Newton-Euler and Composite-Rigid-Body algorithms with a few modifications to make certain aspects relevant for contact detection and control more easily accessible; furthermore, a compliant contact force method alongside stick-slip friction modeled the contact dynamics. To allow the robot to move, a simple PD-independent joint controller was implemented to track a desired leg trajectory. With the same robot and controller implemented using the MuJoCo simulation software, this work evaluates the proposed simulator by comparing characteristic locomotion signals such as the trunk pose and the ground reaction forces. Results showed similar behavior for both simulators, especially with regard to the contact detection, despite the significantly different contact models. Lastly, final remarks to enhance our simulator’s performance are suggested to be explored in future works.
The symbiosis between microorganisms and host arthropods can cause biological, physiological, and reproductive changes in the host population. The present study aimed to survey facultative symbionts of the genera Wolbachia, Arsenophonus, Cardinium, Rickettsia, and Nosema in Cotesia flavipes (Cameron) (Hymenoptera: Braconidae) and Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) in the laboratory and evaluate the influence of infection on the fitness of these hosts. For this purpose, 16S rDNA primers were used to detect these facultative symbionts in the host species, and the hosts' biological and morphological features were evaluated for changes resulting from the infection caused by these microorganisms. The bacterial symbionts studied herein were not detected in the D. saccharalis samples analysed, but the endosymbiont Wolbachia was detected in C. flavipes and altered the biological and morphological aspects of this parasitoid insect. The results of this study may help to elucidate the role of Wolbachia in maintaining the quality of populations/lineages of C. flavipes.
This paper looks at the progress that the Mosaic database has enabled in the study of family structures in continental Europe in the past. Our main argument is that the combination of comprehensive archival research, digitization and computation, data mining, and open-access dissemination that is at the core of the Mosaic project is bringing about an important shift in the fundamental principles that have driven European family history research to date. These transformative features of Mosaic go beyond mere data infrastructural developments, as scaling up to much larger datasets leads to qualitative differences in measurements, methods, and questions. Integrating these perspectives can lead to an important incremental shift in both the scale and the scope of knowledge about historical European family systems.
Moral naturalists are often said to have trouble making sense of inter-communal moral disagreements. The culprit is typically thought to be the naturalist’s metasemantics and its implications for the sameness of meaning across communities. The most familiar incarnation of this metasemantic challenge is the Moral Twin Earth argument. We address the challenge from the perspective of analytic naturalism and argue that making sense of inter-communal moral disagreement creates no special issues for this view.
A narrowly person-affecting (NPA) axiology is an account of the moral ranking of outcomes such that the comparison of any two outcomes depends on the magnitude and weight of individuals’ well-being gains and losses between the two. This article systematically explores NPA axiology. It argues that NPA axiology yields an outcome ranking that satisfies three fundamental axioms: Pareto, Anonymity and, plausibly, Pigou-Dalton. The axiology is neutral to non-well-being considerations (desert); and (assuming well-being measurability) leads to the Repugnant Conclusion (RC). In short, NPA axiology provides a grounding for Paretian, equity-regarding welfarism, albeit one that includes the RC.
In response to the short-term political cycles that govern law-making, there is growing international attention to the obligations owed to future generations. Within the diverse approaches there is often a single, temporally defined inequality; that is, between now and a depleted future. While inequality is imagined between generations, these generations are often constructed as homogenous. This elides not just contemporary inequalities, but that these injustices are caused by historically rooted inequalities that current planetary threats are likely to deepen. In response, we centre health inequalities which illustrate the complex temporalities and structural causes of inequalities. We argue for a focus on eco-social and embodied generations to better understand – and respond to – inequalities past, present and future. We apply this focus to the Capabilities Approach as an example of the work needed to better articulate what is owed to present and future generations to secure justice and inform future-oriented law-making.
Several scholars noted that the pronunciations of 天 “sky” tiān and 風 “wind” fēng in Bai appear to be akin to the western variants of the words attested in the paronomastic gloss dictionary Shìmíng 釋名. I will demonstrate in the current study that there are additional commonalities shared by both Bai and the ancient western dialect, termed Old Western Chinese (OWC) in this study. In both languages, one can identify words with zy- in Middle Chinese (MC) that are pronounced j-. Bai and Old Western Chinese use the same word (椹 shèn) for “fungus”. Furthermore, Old Chinese (OC) cluster *-p/t-s yields -t in both languages in lieu of yielding -j as observed in Middle Chinese. Last but not least, it appears that in both languages, words with *lˤ- (whence MC d-) and -ʔ (whence MC rising tone) are distinct from other words with d- in Middle Chinese. Hence, this paper puts the claim that Bai is akin to Old Western Chinese on a stronger footing. As a side note, judging from the fact that 四 “four” sì contains -t in Old Western Chinese and early Bai, its Old Chinese form most likely ends in *-[t]-s.
Research on the relationship between performance and trust is commonplace in social sciences, yet trust in child protection systems (CPS) remains an emerging area of study. This research delves into how three dimensions of performance – distributive justice, procedural fairness, and functional effectiveness – affect trust in CPS in England and Norway, drawing insights from organisational and social psychology literature. A cross-sectional survey collected data from 981 individuals in England and 1,140 in Norway. Results suggest that procedural fairness and the competences indicator of functional effectiveness significantly and positively impact trust in CPS in both countries. Resources significantly influence trust in Norway’s CPS, while distributive justice has no impact on trust in either country’s CPS. These findings hold theoretical and practical implications for trust in CPS.
In the mid-20th century, The Cold War structured possibilities for politics across the Global South. These strategies were articulated through three competing means to realize the justice and equality promised by newly won independence from colonialism. Global South states could choose from among the following three options, which had many overlaps and intersections: alignment with the United States, alignment with the Soviet Union, and non-alignment. By the 1970s and into the 1980s, left- and right-wing alternatives developed to oppose the limitations of these three perspectives. On the left, Maoism inspired anti-imperialists of the Global South and also sympathizers in the North who stood in solidarity with anti-imperialist struggles. On the right, newly oil-wealthy Saudi Arabia developed a puritanical Islamic alternative to Maoist anti-imperialism and promoted these ideas across Africa and Asia. These ideas did not fall from public consciousness with the formal collapse of the Soviet Union and live on today. My article assesses the different templates for political and economic development that the Cold War engendered, focusing on the legacy of left and right alternatives developed in reaction to their failures. I conclude that these ideological contestations from the Global South reveal that the Cold War was not a mere rivalry between the United States and Soviet Union, it was a global ideological contestation over liberalism; the constituting ideology of capitalism.
A too rarely emphasized feature of modern deontological ethics is the structure of its directives. Faced with alternatives, the question for the moral agent is “which, if either, must I perform (or avoid)?” Getting it right, one is, morally speaking, done…until the next set of freighted options presents. We should wonder whether this makes sense: whether there is not a more complex structure to deontological requirements that resists the “one and done” idea. Rehabilitating the Kantian idea of duty as a value-based deliberative principle, I argue for a more plausible deontology whose requirements are often temporally extended and interpersonally complex.
Pebrine disease, caused by Nosema bombycis (Nb) infection in silkworms, is a severe and long-standing disease that threatens sericulture. As parasitic pathogens, a complex relationship exists between microsporidia and their hosts at the mitochondrial level. Previous studies have found that the translocator protein (TSPO) is involved in various biological functions, such as membrane potential regulation, mitochondrial autophagy, immune responses, calcium ion channel regulation, and cell apoptosis. In the present study, we found that TSPO expression in silkworms (BmTSPO) was upregulated following Nb infection, leading to an increase in cytoplasmic calcium, adenosine triphosphate, and reactive oxygen species levels. Knockdown and overexpression of BmTSPO resulted in the promotion and inhibition of Nb proliferation, respectively. We also demonstrated that the overexpression of BmTSPO promotes host cell apoptosis and significantly increases the expression of genes involved in the immune deficiency and Janus kinase-signal transducer and the activator of the transcription pathways. These findings suggest that BmTSPO activates the innate immune signalling pathway in silkworms to regulate Nb proliferation. Targeting TSPO represents a promising approach for the development of new treatments for microsporidian infections.
Preservation of the genetic diversity of sour cherry in Iran is imperative for the development of improved cultivars tailored to specific ecological conditions. Addressing gaps in research concerning ecological adaptation, resource management and international collaboration related to sour cherry genetic resources in Iran is essential. Bridging these research lacunae can facilitate the implementation of sustainable cultivation practices, optimize production systems and enhance the global utilization of sour cherry genetic diversity. A comprehensive analysis of the morphology and ultrastructure of pollen grains from ten native sour cherry genotypes in Iran was conducted over a two-year period using scanning electron microscopy (SEM). The examination revealed that all pollen grains were unipolar, radially symmetrical and tricolpate. The length and width of pollen grains varied among genotypes, with lengths ranging from 42.17 to 57.57 μm and widths from 20.28 to 28.13 μm. Furthermore, all genotypes exhibited prolate pollen grains, with differing colpus lengths. Examination of pollen exine revealed striate shapes with varying numbers of ridges, ranging from 18.5 to 8.5 furrows per 50 m2. The horizontal area of pollen grains varied from 333.28 to 1491.69 μm. Polar perspective analysis showed considerable variation in the distance between mesocolpium endpoints. Sour cherry displays significant genetic diversity in Iran, and the application of SEM has proven instrumental in characterizing this diversity. This understanding will aid in further breeding research aimed at enhancing sour cherry varieties and their adaptation to specific ecological conditions.
This article examines the history of learning disabilities (LDs) on college campuses, from the introduction of the concept in the early 1960s to its spread throughout American higher education during the 1990s. At first, colleges offered relatively little assistance and urged students to compensate for their LDs by working harder and adopting recommended study strategies. After legal and institutional pressures compelled faculty members to provide accommodations for greater numbers of students, many professors worried about the legitimacy of the diagnosis and the possible threat to academic standards. While casting a somewhat sympathetic light on these concerns, the article concludes that many elements of this early set of accommodations were eventually regarded as pillars of competent instruction. This history illuminates the complex tension between institutional support and student responsibilities and the murky distinction between individual accommodations and universally-effective teaching.
This paper studies various aspects of inverse limits of locally expanding affine linear maps on flat branched manifolds, which I call flat Wieler solenoids. Among the aspects studied are different types of cohomologies, the rates of mixing given by the Ruelle spectrum of the hyperbolic map acting on this space, and solutions of the cohomological equation in primitive substitution subshifts for Hölder functions. The overarching theme is that considerations of $\alpha $-Hölder regularity on Cantor sets go a long way.
