Application of linguistic cues in the analysis of language of hate groups

Hate speech and fringe ideologies are social phenomena that thrive on-line. Members of the political and religious fringe are able to propagate their ideas via the Internet with less effort than in traditional media. In this article, we attempt to use linguistic cues such as the occurrence of certain parts of speech in order to distinguish the language of fringe groups from strictly informative sources. The aim of this research is to provide a preliminary model for identifying deceptive materials online. Examples of these would include aggressive marketing and hate speech. For the sake of this paper, we aim to focus on the political aspect. Our research has shown that information about sentence length and the occurrence of adjectives and adverbs can provide information for the identification of differences between the language of fringe political groups and mainstream media

The Optimal Sample Size in Crosswise Model for Sensitive Questions

The problem is in the estimation of the fraction of population with a stigmatizing characteristic. In the paper the nonrandomized response model proposed by Tian, Yu, Tang, and Geng (2007) is considered. The exact confidence interval for this fraction is constructed. Also the optimal sample size for obtaining the confidence interval of a given length is derived

Organization of General Zionists in Poland (1934–1939)

In 1923, within the framework of the Zionist Organization in Poland (the party was active in former Russian partition and the Pomeranian and Poznań voivodeship) were formed factions, radical Al Hamiszmar and moderate Et Liwnot. The second faction postulated the emigration of Jews from Poland to Palestine based mostly on private funds. Its gathered Zionists belonging the middle and high social classes, well-educated, mostly assimilated culturally pro-Polish. Due to the deterioration of the material situation of Jews and the great economic crisis, its social influence was rapidly decreasing. In 1934, the activists factions formed new party – Organization of General Zionists in Poland. Her leader until 1939 was an attorney Leon Lewite. The party did not have much social influence. It concentrated its efforts on attempts to unite general Zionist party in Poland and in the world. It also tried to define the interests of Jews in city councils and the parliament.W 1923 r. w ramach Organizacji Syjonistycznej w Polsce (partia działała w byłym zaborze rosyjskim oraz województwach pomorskim i poznańskim) powstały dwie frakcje: radykalna Al Hamiszmar i umiarkowana Et Liwnot. Druga frakcja postulowała emigrację Żydów z Polski do Palestyny finansowaną z funduszy prywatnych. Skupiała ona syjonistów należących do warstw średnich i wyższych, dobrze wykształconych, w znacznej części zasymilowanych kulturowo propolsko. Wobec pogarszania się położenia materialnego i wielkiego kryzysu gospodarczego jej wpływy społeczne szybko malały. W 1934 r. działacze Et Liwnot utworzyli nową partię – Organizację Ogólnych Syjonistów w Polsce. Jej przywódcą do 1939 r. był adwokat Leon Lewite. Partia nie miała większych wpływów społecznych. Koncentrowała swe wysiłki na próbach zjednoczenia partii ogólnosyjonistycznych w Polsce i na świecie. Próbowała bronić interesów Żydów w radach miejskich i sejmie

Naczyniak limfatyczny moszny i przestrzeni zaotrzewnowej u 12-letniego chłopca : opis przypadku

Background: Lymphangiomas occurs in children quite frequently. They are most commonly localized in the head, neck, axilla, chest, abdomen, and retroperitoneum. Lymphangiomas of the scrotum are very rare and are usually clinically silent, so they are a challenge for radiologists performing US examination in children. They are obliged to differentiate the following lesions: torsion of the testicle, scrotal hernia, hydrocoele, and epididymal cyst, in addition to the masses of primary extratesticular localization such as hemagioma, congenital vascular malformations, fibromas, and malignant tumors. Additional difficulties appear in boys who present acute scrotum syndrome. Case Report: The paper reports the diagnostics and treatment of a huge multicystic lymphangioma situated in the scrotum and retroperitoneum of a 12-year-old boy who had fallen from a bicycle and presented acute scrotum. The lesion of the scrotum was surgically excised. Retroperitoneal lymphangioma was detected during this operation. Subsequent diagnostics was based on ultrasonography, computerized tomography, and magnetic resonance imaging of the abdominal cavity. The lymphangioma of the retroperitoneum was resected. The patient shows no evidence of recurrence after 7 years. Conclusions: Cystic lymphangiomas are rare but benign intrascrotal, extratesticular, painless masses in children. They are sonographically multicystic or multiloculated abnormalities and may show infiltrative extension to the perineum, retroperitoneum, or abdomen. Recognition of this entity and its extent is important for correct clinical management and may be for planning treatment

The dissection of transcriptional modules regulated by various drugs of abuse in the mouse striatum

BACKGROUND: Various drugs of abuse activate intracellular pathways in the brain reward system. These pathways regulate the expression of genes that are essential to the development of addiction. To reveal genes common and distinct for different classes of drugs of abuse, we compared the effects of nicotine, ethanol, cocaine, morphine, heroin and methamphetamine on gene expression profiles in the mouse striatum. RESULTS: We applied whole-genome microarray profiling to evaluate detailed time-courses (1, 2, 4 and 8 hours) of transcriptome alterations following acute drug administration in mice. We identified 42 drug-responsive genes that were segregated into two main transcriptional modules. The first module consisted of activity-dependent transcripts (including Fos and Npas4), which are induced by psychostimulants and opioids. The second group of genes (including Fkbp5 and S3-12), which are controlled, in part, by the release of steroid hormones, was strongly activated by ethanol and opioids. Using pharmacological tools, we were able to inhibit the induction of particular modules of drug-related genomic profiles. We selected a subset of genes for validation by in situ hybridization and quantitative PCR. We also showed that knockdown of the drug-responsive genes Sgk1 and Tsc22d3 resulted in alterations to dendritic spines in mice, possibly reflecting an altered potential for plastic changes. CONCLUSIONS: Our study identified modules of drug-induced genes that share functional relationships. These genes may play a critical role in the early stages of addiction

Przydatność ultrasonografii w diagnostyce i monitorowaniu leczenia ostrych chorób jamy brzusznej u dzieci z chorobą nowotworową

Background: The aim of this study was to estimate the results of the diagnostic imaging modalities, especially ultrasonography (US) in children during the oncological therapy with the acute abdominal symptoms. Acute abdominal symptoms in children with neoplasms causing a very difficult clinical and diagnostic problems and can occure in any stage of disease. Materials/Methods: We analyzed 249 ultrasounds examinations of the abdominal cavity in 144 girls and 105 boys aged from 1 to 18 years (mean age 1o, 3 years). The more important indication for the US exam in 133 cases was acute abdominal symptoms. We took exams during pre- and postoperative chemotherapy, radiotherapy and after the hematopoietic stem cell transplantation. All the patients were under routine hematological control. Based on the clinical symptoms and the laboratory tests we analysed two groups of children with oncological disease and acute abdomen: I group-111 children with neutropenia, II group-22 children without neutropenia. In the patients who underwent operation procedure the final diagnosis was established on histopathology. In the other cases diagnosis was based on clinical, laboratory and radiological exams, especially ultrasonography. We analyzed clinical picture of disease, the results of therapy and the US changes in examed patients using statistic parameters as: sensitivity, specificity and efficiency. Results: In the group of 133 children with acute abdominal symptoms the most (92- 69,1%) patients suffer from ALL (acute lymphoblastic leukaemia) and 16(12%) - from AML (acute lympoblastic leukaemia), Ewing sarcoma-3(2,2%), osteosarcoma-3(2,2%), NHL-8(6,0%), HL-4(3%), nephroblastoma-4(3%), neuroblastoma- 3( 2,2%). Acute abdominal symptoms can have a very different etiology: bacterial, mycotic and virusal infections or continious infiltration of gastrointestinal tract by tumor. Clinical symptoms of the acute abdominal diseases are very severe, because the oncological patients usually have immunologic deficiency and oblige us to proper clinical observation or to operation procedure, very often as an emergency. The symptoms appeard in the different time of course of oncological diseases. Nonspecific gastrointestinal inflammation with haemorrhage and typhlitis were the main cause of the acute abdominal pain in 71 children with neutropenia during therapy of leucaemia, lymphoma, aplastic anemia and after hematopoietic stem cell transplantation. The accuracy of ultrasound findings verified intraoperatively and by histopathologic examinations was 84%. In all cases the morphological changes were directly related to the signs and symptoms duration. Conclusions: The high-resolution ultrasound has a very important role in diagnosis in all patients with acute abdominal pain and with neoplasms. The authors consider that the US should be the first imaging method in the differential diagnosis of the abdominal changes in children with neutropenia and oncological disease. Proper diagnosis should be established only with clinical information
