Within the project “Pragmatics above grammar: Subjectivity and intersubjectivity in Estonian registers and text types” (PRG341) we are studying the expression of subjectivity and intersubjectivity in different written and spoken registers of modern Estonian. We focus on adverbs that function as discourse markers (e.g. vist ‘maybe, probably’, ilmselt ‘apparently, obviously’, tegelikult ‘actually’), markers that develop from main clauses containing cognition verbs that take sentence complements (e.g. (ma) arvan ‘I think’, usun ‘I believe’, (mulle) tundub ‘it seems (to me), it appears (that)’) as well as modal and performative verbs (e.g. võib (juhtuda) ‘can (happen’, peaks (tulema) ‘should (come)’; kinnitan/väidan (olevat) ‘I affirm/claim’). The analysis combines quantitative corpus-linguistic and qualitative pragmatic approaches, thus belonging to the field of corpus pragmatics. Unlike previous studies of related topics, the project systematically compares the usage of markers in different registers (spoken, online communication, print texts) and text types. The pilot studies performed thus far have revealed several problems with the existing Estonian corpora, important in the study of pragmatics. Firstly, some text types are underrepresented or not represented at all, the text types cannot always be distinguished, and the particular text may not always correspond to the nominal text type (e.g. an academic text may contain quotes from texts of other types). All of this makes it difficult to do comparative statistical analysis of different text types. Secondly, the markers under examination are multifunctional and identifying their (inter)subjective function requires consideration of context broader than a single sentence. However, the public search systems for the existing corpora do not provide this context. For instance, the discourse marker function of cognition verbs is indicated primarily by the fact that the topic of the conversation or text follows through the subordinate clause, not the main clause. Since the available search systems do not provide context larger than a single sentence, the identification of the topic of the discourse, and therefore of the potential discourse-marker function of the verb, is made more difficult. To avoid these problems, the project working group is developing a new “Pragmatics” corpus, being created in the SketchEngine environment. The corpus is made up of 10 subcorpora representing different text types and registers. Each subcorpus contains roughly 500,000 words.

PurposeRisk is part of corporate activity and a consequence of the businesses' demands, the market and the changes in companies and their surroundings. The way that risk is managed is different between family and non-family businesses. The paper aims to compare the different risk types experienced in the context of the coronavirus disease (COVID-19) pandemic among family and non-family businesses and to analyze whether operational, legal, strategic and image risks influence financial risks.Design/methodology/approachThe nature of the study is quantitative and based on a questionnaire survey that analyses the perception of risks by 1,090 family businesses and 557 non-family businesses.FindingsThe results show the existence of statistically significant differences in the perception of financial and legal risks between family and non-family businesses, where the former being the businesses that give more importance to these risks. The perception of operational, legal, strategic and image risks have a positive influence on the perception of financial risk in family and non-family businesses.Originality/valueThe results obtained in the study are important because they allow an understanding about the differences in risk management between family and non-family businesses, which can lead to greater corporate sustainability and increased financial performance.

Background. The study of the sensitive portion of the medial plantar nerve is relevant not only in the examination of patients with tibial nerve mononeuropathy or its branches, but also in the diagnosis of polyneuropathies.Objective: to analyze the normative parameters of the sensory potential recorded during the study of the medial plantar nerve by the orthodromic method in healthy adults.Materials and methods. 126 sensitive fibers of the medial plantar nerves were studied on the Dantec Keypoint G4 device (Denmark) in 63 healthy individuals (31 men and 32 women; age from 20 to 80 years). 3 groups were identified taking into account age: group 1 included healthy people aged 20 to 39 years (n = 23); group 2 consisted of people aged 40 to 60 years (n = 20); and 3 – older than 60 years (n = 20). The parameters of the sensory potential of the medial plantar nerve are analyzed.Results. The sensory potential in the study of the sensitive portion of the medial plantar nerve was registered in all 126 healthy subjects. Comparative statistical analysis did not demonstrate significant differences between groups 1–3 in the values of such parameters of the sensory potential as the latency of the onset, the duration of the negative phase and the rate of propagation of excitation. At the same time, in groups 2 and 3, the magnitude of the amplitude from peak to peak of the sensory potential was significantly lower compared to group 1, and averaged 8.92 and 7.86 MV, respectively.Conclusion. Knowledge of the regulatory parameters will allow expanding the use of electroneuromyography of the sensitive portion of the medial plantar nerve in clinical and research practice.

In this paper we have focused on measuring the gender inequality index in relation to some important indicators that reflect gender inequality in social, economic, political, and educational terms. Our study aims to reflect the differences in gender inequality through the gender inequality index for 2013-2020 in relation to these important indicators such as reproductive health, which includes maternal mortality per 1000 live births and fertility rate of teenagers. Another indicator is the empowerment, which includes the percentage of seats in parliament on a comparative basis by gender and completion of secondary or higher education by gender. Another indicator is the labor market, which includes the degree of participation in the labor market. Precisely, in relation to these indicators and according to the annual periods taken into consideration in the study, we have analyzed the index of gender inequality between women and men. Measuring gender inequality is very important for the fact that it highlights many problems related to the social, economic, political, educational development of a country. The data is provided by INSTAT (Institute of Statistics, Albania), based on social surveys and administrative resources by gender. The paper is based on the descriptive method, from which comparative statistical analysis related to the gender inequality index are derived through data processing, by years and by important indicators obtained in the study. This study is also focused on recommending some important policies to be undertaken by the government to improve the gender inequality index in relation to the indicators we have taken into consideration in our study.   Received: 13 July 2021 / Accepted: 26 August 2021 / Published: 5 September 2021

Objective Retosiban, an oxytocin receptor antagonist, was developed for treating spontaneous preterm labor (sPTL) in women with intact membranes. This ARIOS follow-up study aimed to characterize clinical safety, morbidity, and mortality of infants exposed to retosiban or comparator over 2 years. Study Design ARIOS prospectively assessed outcomes in infants whose mothers received at least one dose of retosiban or comparator (placebo/atosiban) in two Phase 3 sPTL trials. Both trials were terminated prematurely owing to poor enrolment. Infants could be enrolled into ARIOS from 28 days after estimated due date until hospital discharge or up to 9 months (corrected age). An internally developed questionnaire detailing medical conditions, mortality and resource use (Child Health Inventory; CHI), Ages and Stages Questionnaire-3 (ASQ-3), Modified Checklist for Autism in Toddlers–Revised with Follow-Up, and Child Behavior Checklist for Ages 1.5 to 5 were completed remotely by parents or legal guardians at prespecified intervals. Serious adverse events (SAEs) were primarily captured via CHI. No comparative statistical analysis was conducted between treatment arms. Results A total of 49 (86%) infants who had received retosiban and 49 (78%) infants who had received a comparator were enrolled in ARIOS. No deaths occurred during the study. Nine infants experienced SAEs: 6/49 (12.2%) infants in the comparators group and 3/49 (6.1%) in the retosiban group. Of the nine SAEs, seven were due to infections, three, and four in the retosiban and comparators groups, respectively. Based on ASQ-3 score, the incidence of neurodevelopmental delay at 18 and 24 months were 0/18 (0%) and 2/25 (8%) with retosiban and 7/22 (31.8%) and 3/21 (14.3%) with comparator, respectively. Conclusion The current study showed no unexpected adverse outcome or impairment with retosiban based on safety monitoring and neurodevelopment assessments. No further follow-up is intended owing to the discontinuation of clinical development of retosiban. Key Points

In order to assess the proliferative behaviour of the ameloblastoma epithelium nine cases of this neoplasm were retrieved from the files of the Oral Pathology Service laboratory of Rio Grande do Sul Federal University School of Dentistry. Two proliferation marker techniques were employed: the AgNor - argyrophilic nucleolar organizer regions staining and the proliferation cell nuclear antigen (PCNA) immunohistochemical assessment technique. Each case was submitted to a quantitative and comparative statistical analysis of the results obtained for the two techniques. The conclusion arrived at shows ameloblastoma presenting benign behavior, an average AgNOR index of 1.612, and a PCNA proteindependent proliferative activity with average immunoreactivity of 51.61%. The histological patterns analyses of the neoplastic epithelial component demonstrates that cells resembling pre-ameloblasts have obtained figures statistically higher to those obtained for cells resembling the stellate reticulum of the enamel organ, in both techniques employed. Therefore, it might be inferred that cells resembling pre-ameloblasts hold the proliferative potential of ameloblastomas and are probably responsible for the growth characteristics and infiltrative ability of this tumour.

This research aims to compare the cultural dimensions of the automotive industry in three countries, Brazil, Argentina, Mexico and discuss Hofstede model. Were using two techniques of analysis, the first being described in the model of Hofstede and Minkov (2013) and the second using the statistical technique indicated by critics of the model (McSweeney, 2013). The results found in regions of Brazil and Mexico indicate that in the same country there may exist different values of cultural dimensions. Regarding the critics indicated in the literature on the model used, this study found evidence in line with the critics that the model, although pointing to cultural differences are not supported by statistically significant differences, to measure and compare cultures between countries. As a contribution, this study indicates the need for the proposed model to consider robust statistical techniques, probabilistic sampling and comparative statistical analysis techniques to prevent misdiagnosis.

The aim of this study was a comparative statistical analysis of three categories of maxillary odontogenic cysts, evaluating frequency in relation to localization (mandibular or maxillary region), age and gender of patients. The study was a retrospective cohort study conducted at the University Hospital of Messina. Three hundred and fifty-six maxillary odontogenic cysts were classified into 283 inflammatory, 43 developmental and 30 neoplastic cysts. Female patients are more affected by developmental odontogenic cysts, while male patients are more affected by inflammatory odontogenic cysts. Both the mandibular and maxillary regions were affected mainly by inflammatory odontogenic cysts; no significantly statistic relationship was found between lesions and age. A significant association between odontogenic cyst lesions and patient gender was found. No significant association between histological features of lesion and age of patient was observed, nor subtype of odontogenic disease and localization (mandibular or maxillary).
