Preliminary study on the feasibility of approximating children's engagement level from their emotions estimation by a picture-based, three-model AI in a family-robot cohabitation scenario

Haru4Kids (H4K) is a system that emulates the physical, social, family-oriented robot Haru, designed with the goal of cohabitating with children in their homes for extended periods of time. In a previous experiment [Garcia GA, Perez G, Levinson L, et al. Living with Haru4Kids: study on children's activity and engagement in a family-robot cohabitation scenario. In: 2023 IEEE ROMAN; 2023 Aug. p. 1428–1435], seven families kept H4K for a span of two weeks in their homes. Throughout this period of cohabitation, we collected child-robot interaction data, including images that were later hand-annotated to estimate user engagement. In this present work, we used a novel AI-based, four-stage framework available from Roboflow for the automatic estimation of children's level of engagement from their inferred emotions. We did a deep study of the performance and behaviour of that framework over our dataset of users' pictures and characterized its response in order to understand its advantages and limitations, including the technique used to translate emotions into engagement levels. We also tested a different approach for that mapping, using a machine learning technique based on Support Vector Machine (SVM). The framework yielded promising results just ‘off-the-shelf’: 0.47–0.68 accuracy and 0.46–0.70 F1 using the original mapping, and 0.39–0.75 and 0.37–0.78 respectively using SVM. Therefore, we propose this emotion-based approach for engagement estimation from pictures.

The influence of good faith on the right to receive maintenance from a spouse or former spouse

With the registration of the marriage certificate, the spouses are mutually and jointly obligated to provide each other with material maintenance and moral support, both during the marriage and after its dissolution. When establishing the payment of alimony from the spouses, both the period of cohabitation of the spouses that gives the right to maintenance and after the dissolution of the marriage will be taken into consideration. The role of the court is essential, manifested through the meticulous examination of all the factual and legal circumstances that influence good faith in the right to receive maintenance from a spouse or former spouse. When determining the right that gives rise to the maintenance obligation, the court will assess the evidence submitted in the case, taking into account the principle of good faith or its absence. The court may dismiss the application if it considers that the spouse requesting the maintenance obligation has acted contrary to good faith.

Population Dynamics and Distribution of the Lake Smelt, a Dwarf Form of the European Smelt Osmerus eperlanus (Osmeridae), and the Black Sea Sprat Clupeonella cultriventris (Clupeidae) while Cohabiting the Rybinsk Reservoir

The data for a 23-year period (2000–2022) on the population dynamics and distribution of the lake smelt (a form of the European smelt Osmerus eperlanus) and the Black Sea sprat Clupeonella cultriventris in the Rybinsk Reservoir have been summarized. The lake smelt dominated the reservoir pelagial from the 1950s to the mid-1990s. An anomalously low water level in the reservoir in 1996 and abnormal (for this reservoir) water warming in subsequent years led to elimination of the species from the reservoir ichthyofauna in 2002. The Black-Sea sprat invaded the reservoir in the mid-1990s; its population irruption occurred in the early 2000s (during the depressed state of the smelt population). Currently, this species dominates in the pelagial of the reservoir. Since the early 2000s there were noted two periods when the lake smelt was found in practically all parts of the Rybinsk Reservoir and the sprat abundance was also high. However, high water temperatures in 2010 and 2021, as well as low level in 2014, resulted in almost complete disappearance of the lake smelt disappeared. During the periods of cohabitation of the studied species, a significant similarity in the diet of individuals of both species with the size of up to 80 mm has been noted. The larger smelt fed on larger plankton, and in the summer also on fish. Currently, the main limiting factor negatively affecting the recovery of the smelt population in the Rybinsk Reservoir is the abnormal heating of the water column in some years.

Effects of chronic social defeat on social interaction and partner preference in mandarin voles

Abstract Different types of stress produce different effects on social relationships between partners. Chronic social defeat has been found to alter the emotional and social behaviours, whether it affects partner preference remains unclear. Using monogamous mandarin voles (Microtus mandarinus), the present study found that 14 days of social defeat to male vole could increase social avoidance in sociality test, and reduced attacking, intimate, sniffing and exploratory behaviours, but increased avoidance defensive, immobile behaviours in social interaction test. In addition, this treatment significantly reduced side-by-side contact with partner throughout cohabitation period, and reduced the attacking behaviour to strangers after 11 days’ cohabitation. Furthermore, in mandarin vole with chronic social defeat, partner preference was abolished on 5 and 7 days’ cohabitation indicating that pair bonding stability was impaired by chronic social defeat. Moreover, although mandarin voles spent longer time rescuing partner than stranger in both groups, chronic social defeat did not affect rescuing significantly. Impairment of pair bonding may be due to abnormalities in social interaction induced by chronic social defeat. This finding provides some insights into mechanisms underlying effects of prolong social stress on social relationships between partners.

Pooling of Wealth in Marriage: The Role of Premarital Cohabitation

Previous studies documented the existence of a ‘cohabitation–marriage gap’ in resource pooling among opposite-sex partners, with cohabiters being more likely to separate income and wealth than married individuals. Surprisingly, despite many non-marital cohabitations transform into marriages, we know little about income and wealth pooling of ‘spousal cohabiters’, i.e. spouses who transition to marriage after experiencing a period of non-marital cohabitation. The comparison between ‘spousal cohabiters’ and directly married spouses is particularly interesting because it offers a litmus test of theories of marriage in relation to how and why economic resources are differently distributed within married vs. cohabiting couples. This paper compares directly married couples and ‘spousal cohabiters’ in Italy, focusing on one aspect of resource pooling: the marital property regime, i.e. the choice made at the time of marriage between joint or separate ownership of wealth accumulated during marriage. Competing hypotheses are developed on the basis of the arguments that marriage yields legal protection, that selection mechanisms drive both the choice of community vs. separation of property and direct marriage vs. premarital cohabitation, and that, by inertia, ‘spousal cohabiters’ continue to separate resources upon transition to marriage. Results based on the 2016 Italian ‘Family and social subjects’ survey show that ‘spousal cohabiters’ are significantly more likely to choose separation of property compared to directly married spouses. Such differences, however, are drastically reduced once relevant confounders are controlled for, hence suggesting that existing differences between directly married and previously cohabiting couples and, more generally, differences between married and cohabiting couples are driven, above all, by selection mechanisms.

Origin of <i>Candida albicans</i> in Human Oral Cavity

Purpose: Candida albicans is regarded as a part of normal flora in the human oral cavity. However, it remains unclear whether the genus Candida, especially C. albicans, is an oral resident microorganism and causes marital infection or not. The purpose of the present study was to elucidate the origin of oral C. albicans by investigating the colonization and infection route to oral cavities of this organism with arbitrarily primed polymerase chain reaction (AP-PCR). Methods: After C. albicans was isolated from four subjects (average age: 42.2, range: 33 - 56), the isolations of this organism from them were performed six months later again. To investigate whether C. albicans is an oral resident microorganism, the genotype homology of each C. albicans isolates that were isolated twice from the same subjects was compared. Moreover, C. albicans was isolated from five pairs of married couples (average period of cohabitation: 12.4 years, range: 5 - 31). To investigate whether C. albicans causes marital infection, the genotype homology of C. albicans isolates that were isolated from each pair of married couples was compared. Results: AP-PCR patterns of C. albicans that were isolated from each subject at o month and after 6 months showed the identical genotypes among each individual. C. albicans isolates from five pairs of married couples showed the identical genotypes between a husband and wife of each pair on AP-PCR. Conclusion: These results indicated that C. albicans was an oral resident microorganism and caused the marital infection.

Impact of male-female cohabitation period on behavioral aspects, fertility, hatchability, and hormonal estimates of Japanese quail

To evaluate the impact of male-female cohabitation period on the fertility, hatchability, injuries response, and some hormonal estimates in Japanese quails. A total of 288 mature Japanese quails were equally divided into 3 groups (3 groups × 8 replicates × 12 birds), with 1 Male: 2 Females sex ratio. In the first group (control), male and female quails were reared continuously together, while the males in the second and third groups were reared together with females once or twice/wk times (24 h/ time), respectively throughout the experiment. The obtained results showed that final body weight (FBW/g), fertility (%), and hatchability (%) in the second and third groups significantly (P ≤ 0.01) increased compared with the control group. Laying quails in the second and third groups significantly (P ≤ 0.01) produced more and heavier eggs, while the feed consumption and feed conversion ratio were significantly (P ≤ 0.01) decreased compared with the control group. The injuries response for both sex in the second and third groups significantly (P ≤ 0.01) decreased compared with the control group. The cloacal size (mm2) for quails in the third group significantly (P ≤ 0.01) increased than those of the first and second groups, while the testes (%) were not affected. The testosterone hormone concentration for male chickens in the second and third groups significantly (P < 0.01) decreased, while the female progesterone hormone concentration (ng/mL) significantly (P < 0.01) increased compared with the control group. The means of red blood cells (RBC/106), white blood cells (WBC/103), and hemoglobin (g/dL) for quails in the second and third groups significantly (P < 0.01) increased, while heterophil/lymphocyte (H/L ratio) significantly (P < 0.01) decreased compared with the control group. Thus, it could be concluded that the reduction male-female cohabitation period of quails is recommended for improving the fertility and hatchability percentages as well as and some hormonal estimates.

Prvi ministar (premijer) Pete francuske Republike - između značajnog ustavnog položaja i preovlađujuće prakse u senci šefa države

One of the characteristics of the system of government in the Fifth French Republic is the strengthened position of the head of state, but also the existence of the first minister as a constitutional category with a significant role. The constitution provides the political responsibility of the government with the Prime Minister and ministers before parliament. Certain French writers have opinion that the Prime Minister appears as the central figure of the constitutional structure. The Prime Minister shall direct the actions of the Government. This is 21 of Constitution. Also, there are specific powers that put the Prime Minister in the position of its real head of government. Among the prime minister's most important powers is his right to elect members of the government. It is the right to propose to the President of the Republic the appointment but also the dismissal of members of the government. The Prime Minister is authorized to re-sign certain acts of the President of the Republic. In case of temporary impediment of the head of state, the Prime Minister chairs the councils and committees for national defense, as well as the Council of Ministers. The paper analyzes the constitutional provisions that lead to the conclusion that the position of the Prime Minister is institutionally constructed as strong. Political practice, with the exception of periods of cohabitation, has indicated that most prime ministers have been overshadowed by mostly powerful heads of state. For that reason, it is necessary to analyze the political practice of all eight presidential governments. A review of the already long political life that has lasted since 1958. points to the conclusion that in its longest period, presidents of the Republic dominated the public political scene. The Prime Minister has a more pronounced role in the executive branch during cohabitation periods. However, nine years in three cohabitations cannot change the central conclusion of this paper that the dominant political practice of the Fifth Republic has led to the Prime Minister being essentially in the shadow of the head of state.

How Mathematical Economics Became (Simply) Economics: The Mathematical Training of Economists during the 1940s, 1950s, and 1960s in the United States

Before the use of mathematics in economics was generalized, mathematical and nonmathematically trained economist lived together. This paper studies this period of cohabitation. By focusing on the communication challenges between these two groups during the 1940s, 1950s, and 1960s, a watershed moment, this paper analyzes the entrance of mathematics into economists’ training. The paper explores the development of teaching materials specific for the mathematical training of social scientists, the entrance of mathematics to the economics curriculum, and the role of the Social Science Research Council in this delivered process. All these elements are integral to understand how the mathematical methods and tools introduced by a small group of economists during the mid-twentieth century came to be adopted by the entire discipline within a couple of decades and thus effected a permanent transformation of economics.

Inducing Partner Preference in Mice by Chemogenetic Stimulation of CA2 Hippocampal Subfield.

Social recognition is fundamental for social decision making and the establishment of long-lasting affiliative behaviors in behaviorally complex social groups. It is a critical step in establishing a selective preference for a social partner or group member. C57BL/6J lab mice do not form monogamous relationships, and typically do not show prolonged social preferences for familiar mice. The CA2 hippocampal subfield plays a crucial role in social memory and optogenetic stimulation of inputs to the dorsal CA2 field during a short memory acquisition period can enhance and extend social memories in mice. Here, we show that partner preference in mice can be induced by chemogenetic selective stimulation of the monosynaptic projections from the hypothalamic paraventricular nucleus (PVN) to the CA2 during the cohabitation period. Specifically, male mice spend more time in social contact, grooming and huddling with the partner compared to a novel female. Preference was not induced by prolonging the cohabitation period and allowing more time for social interactions and males to sire pups with the familiar female. These results suggest that PVN-to-CA2 projections are part of an evolutionarily conserved neural circuitry underlying the formation of social preference and may promote behavioral changes with appropriate stimulation.

Ewolucja ustroju politycznego V Republiki

Evolution of the Constitutional System of the V Republic. A Few Reflections&#x0D; The Constitution of the Fifth Republic of France after the reform of 1962 (introduction of the presidential election in a general vote) establishes, on a legal level, a semi-presidential system. Depending on the results of the presidential and parliamentary elections – in particular to the National Assembly – their result pointed towards “presidentialisation” of the system, meaning that the President could have in practice full executive powers (the government was responsible) or periods of cohabitation (cooperation), when the parliamentary majority represented an opposition option to the President of the Republic and the constitutional system revealed its parliamentary characteristics. The domination of the president in the Fifth Republic resulted not only (though mainly) from the political forces active at the time. Its sources are elucidated in article 5 of the Constitution, defining the functions of the president as the guardian of the Constitution and ensuring, through its arbitration, the regular functioning of public authorities and the continuity of the state. It is a tradition of republican France that political practice gives constitutional shape to legal constitutional norms; this was the case in the Fourth Republic, and even more so in the Third Republic.

Elementy prezydencjalizmu w systemie ustrojowym Francji okresu V Republiki

Elements of Presidentialism in the Constitutional System of France’s Fifth Republic The Fifth French Republic was created as a modified parliamentary system, but due to constitutional changes and tendencies revealed in political practice, the functioning system of government was quite significantly modified. The purpose of this article is to analyze the elements of the presidential system that were introduced in 1958, thus in the original text of the constitution, resulted from its subsequent amendments, or can only be seen in the practice of exercising power in the conditions of the politically homogenous executive branch, i.e. outside of cohabitation periods. The author draws attention to two different ways of defining the term “presidentialism” in the French context (as a formal constitutional structure or as a pro-presidential configuration of the semi-presidentialism of the Fifth Republic), and argues that the regime initiated in 1958 is still based on at least some pillars characterizing the parliamentary model. Hence, its subsequent modifications were only to highlight presidentialism as one of the possible variants of political practice under the Fifth Republic, and not to accept presidentialism as a constitutional system of government.

ПОХОДЖЕННЯ ШВЕДІВ (ІСТОРИКО-ЛІНГВІСТИЧНИЙ АНАЛІЗ ЕТНОСУ)

The article is dedicated to the problem of the origin of the Swedes tribe against the background of Indo-European ethnogenesis in comparison with the Rus tribe, which were formed on the basis of territorial and pagan proximity to a relatively single ethnic group and a super-language (koine) on the Don. The study is based on the mythological material of the Ynglinga saga and the Book of Veles, lexicographic, toponymic features of the indicated tribes, in which the roots of the ethnic groups stand out. The latter is confirmed in Finnish names regarding the country of Sweden, which the Finns call Ruotsi, Ruossi, Ruohti, Ruotti, the Votes – Rôtsi, the Estonians – Rôťs, on the other hand, the name of the country Sweden has the ancient forms of Swes, Sues, Swēorice “Kingdom of the Swedes” and modern with the meaning “Sweden”: Icelandic Svíþjóð, Swedish Sverige. The origin of the Slavic and German ethnic groups occurred during the period of cohabitation of these peoples in the Indo-European proto-ethnics on the banks of the Don River, approximately in the second millennium BC. These origins include the origin of Indo-European root of kweruki, which the names of the ethnic groups are evolved from: * kweruχi (palatalization)&gt; rusi&gt; rusy “Rus” and * kwеruki ~ * ruti (substitution)&gt; fin. ruotsi “swedes”. The Indo-European root of *kwa in the meaning of “Universe, God” is the origin of Germanic *sve- / swe-, which gave birth to the names of Suionen (Tacitus), Swēorice “Kingdom of the Swedes” and Swerikl, Swealand, Swithiod, as well as Latin Svedia, Svecia, Sveonia with the meaning “Sweden”. The above is proved by the presence of the common goddess Mother-SVA (Slavs) and Moder Svea (Swedes).

Neural circuitry of social learning in Drosophila requires multiple inputs to facilitate inter-species communication

Drosophila species communicate the threat of parasitoid wasps to naïve individuals. Communication of the threat between closely related species is efficient, while more distantly related species exhibit a dampened, partial communication. Partial communication between D. melanogaster and D. ananassae about wasp presence is enhanced following a period of cohabitation, suggesting that species-specific natural variations in communication ‘dialects’ can be learned through socialization. In this study, we identify six regions of the Drosophila brain essential for dialect training. We pinpoint subgroups of neurons in these regions, including motion detecting neurons in the optic lobe, layer 5 of the fan-shaped body, the D glomerulus in the antennal lobe, and the odorant receptor Or69a, where activation of each component is necessary for dialect learning. These results reveal functional neural circuits that underlie complex Drosophila social behaviors, and these circuits are required for integration several cue inputs involving multiple regions of the Drosophila brain.

Observation of parasitic behaviour of an invasive neozootic fish species, the topmouth gudgeon, Pseudorasbora parva (Actinopterygii: Cypriniformes: Cyprinidae), on other cyprinid fishes

The objective of this study was to observe and document behavioural factors of parasitism of an invasive neozootic fish species&mdash;the topmouth gudgeon, Pseudorasbora parva (Temminck et Schlegel, 1846)&mdash;on different cohorts of 1-year-old and 2-year-old common carp, Cyprinus carpio Linnaeus, 1758, as well as 3-year-old tench, Tinca tinca (Linnaeus, 1758), after the overwintering period in ponds and subsequently in aquaria. Fishes cohabited the ponds for seven months and the aquaria for one month. After this period carp and tench were examined for visible lesions on the body surface. During the cohabitation period cyprinids were actively nibbled by the neozootic fish species P. parva. Such attacking or nibbling caused injuries on the skin and deep lesions, which can be interpreted as predation or even parasitism.

Угорські запозичення в західноукраїнських топонімічних переказах

The oral folk prose of Transcarpathia is a valuable source of history and culture of the region. Supplementing the written sources, it has maintained popular attitudes towards events, giving assessments and interpretations that are often different from the official one. In the Ukrainian oral tradition, we find many words borrowed from other languages, in particular Hungarian, which reflects the long period of cohabitation as well as shared historical events and contacts. They also occur in local toponymic legends, which in their own way explain the origin of the local names and are closely linked with the life and culture of the region, contain a lot of ethnographic, historical, mythological, and other information. They are represented mainly by lexical borrowings, Hungarian proper names and realities, which were transformed, absorbed and modified in another system, and, among other things, has served the originality of the Transcarpathian folklore. The process of borrowing the Hungarianisms is marked by heterochronology and a significant degree of assimilation in the receiving environment. It is known about the long-lasting contacts of the Hungarians with Rus at the time of birth of the homeland - the Honfoglalás, as evidenced by the current geographical names associated with the heroes of the events of that time - the leaders of uprisings Attila, Almash, Prince Latorets (the legends Almashivka, About the Laborets and the White Horse Mukachevo Castle). In the names of toponymic legends and writings there are mentions of the famous Hungarian leaders, the leaders of the uprisings - King Matthias Corvinus, Prince Ferenc Rákóczi II, Lajos Kossuth (the legends Matyashivka, Bovtsar, Koshutova riberiya). Many names of villages, castles and rivers originate from Hungarian lexemes and are their derivatives, explaining the name itself (narratives Sevlyuskyy castle, Gotar, village Gedfork). The times of the Tatar invasion were reflected in the legends The Great Ravine Bovdogovanya and The village Goronda. Sometimes, the nomination is made up of two words - Ukrainian and Hungarian (Mount Goverla, Canyon Grobtedie). In legends, one can find mythological and legendary elements. The process of borrowing Hungarianisms into Ukrainian is marked by heterochronology, meanwhile borrowings remain unchanged only partially, and in general, they are assimilated in accordance with the phonetic and morphological rules of the Ukrainian language. Consequently, this is a creative process, caused by a number of different factors - social, ethnocultural, aesthetic, etc. In the course of time, events and characters in oral narratives are erased from human memory, so they can be mixed, modified and updated, adapting to new realities.

Period of Weed Interference in Bean With Nitrogen Fertilizer

The competition between weeds and bean plants, mainly by nutrients of the environment, is one of the main causes of low crop yield. Therefore, the objective of this study is to evaluate the effects of nitrogen fertilization on the extension of the period prior to interference (PPI) in common beans, cultivar TAA GOL. Sowing was performed in conventional system. The treatments were divided into two groups: cover nitrogen fertilization (200 kg urea ha-1) and no cover fertilization. Within each area, we established periods of cohabitation of the crop with weeds from the emergence up to seven times of its life cycle (0-10, 0-20, 0-30, 0-40, 0-50, 0-60, 0-70 days) and a control. The experiment design was randomized blocks with three replicates. Digitaria spp. presented a greater relative importance in both areas, followed by Eleusine indica. The period prior to weed interference (PPI) in the area with nitrogen fertilization occurred up to 46 days after emergence (DAE), and only up to 3 DAE for the area without cover fertilization. There was a 30% decrease in bean productivity by comparing the area with nitrogen fertilization (2,004.79 kg ha-1) and the area without nitrogen fertilization (1,412.43 kg ha-1). Therefore, nitrogen fertilization increased crop yield and favored it competitively in relation to weeds by increasing the weed PPI.

Early preclinical detection of prions in the skin of prion-infected animals

A definitive pre-mortem diagnosis of prion disease depends on brain biopsy for prion detection currently and no validated alternative preclinical diagnostic tests have been reported to date. To determine the feasibility of using skin for preclinical diagnosis, here we report ultrasensitive serial protein misfolding cyclic amplification (sPMCA) and real-time quaking-induced conversion (RT-QuIC) assays of skin samples from hamsters and humanized transgenic mice (Tg40h) at different time points after intracerebral inoculation with 263K and sCJDMM1 prions, respectively. sPMCA detects skin PrPSc as early as 2 weeks post inoculation (wpi) in hamsters and 4 wpi in Tg40h mice; RT-QuIC assay reveals earliest skin prion-seeding activity at 3 wpi in hamsters and 20 wpi in Tg40h mice. Unlike 263K-inoculated animals, mock-inoculated animals show detectable skin/brain PrPSc only after long cohabitation periods with scrapie-infected animals. Our study provides the proof-of-concept evidence that skin prions could be a biomarker for preclinical diagnosis of prion disease.

Craft(ing) Narratives: Specimens, Souvenirs, and “Morsels” in A la Ronde’s Specimen Table

This article explores the relationship between souvenir acquisition and the construction of narrative in the interior decoration of A la Ronde in Devon, home to cousins Jane and Mary Parminter. During their 1796–1811 period of homosocial cohabitation, the Parminters ornamented the property with handcrafted objects and spaces, often fabricated from sou venirs, found objects, and pieces from their family collection. While the secondary literature on A la Ronde emphasizes the appropriateness of so-called feminine crafts such as shell-work and paperwork for the decoration of a female space, this article reveals how the cousins used material objects to create complex domestic, familial, and touristic narratives. Focusing on a specimen table made around 1790, the article situates its production in rela tion to the histories of the Parminter family, their residence in Devon, and their extensive Continental tour. Utilizing frameworks from period travel writing, it demonstrates how the collection and creation of such objects was indivisible from the construction of narrative.

Drosophila species learn dialects through communal living.

Many species are able to share information about their environment by communicating through auditory, visual, and olfactory cues. In Drosophila melanogaster, exposure to parasitoid wasps leads to a decline in egg laying, and exposed females communicate this threat to naïve flies, which also depress egg laying. We find that species across the genus Drosophila respond to wasps by egg laying reduction, activate cleaved caspase in oocytes, and communicate the presence of wasps to naïve individuals. Communication within a species and between closely related species is efficient, while more distantly related species exhibit partial communication. Remarkably, partial communication between some species is enhanced after a cohabitation period that requires exchange of visual and olfactory signals. This interspecies “dialect learning” requires neuronal cAMP signaling in the mushroom body, suggesting neuronal plasticity facilitates dialect learning and memory. These observations establish Drosophila as genetic models for interspecies social communication and evolution of dialects.
