Hate Speech Detection Using Text Mining and Machine Learning

Automatic hate speech detection on social media is becoming an outstanding concern in modern countries. Indeed, hate speech towards people brings about violent acts and social chaos, hence law prohibits it, and it engenders moral and legal implications. It is crucial that we can precisely categorize the hate speech, and not a hate speech automatically, while this allows us to identify easily real people who represent a threat for our society, and who wrongly regard as hateful speakers. In this paper, we applied a complete text mining process and Naïve Bayes machine learning classification algorithm to two different data sets (tweets_Num1 and tweets_Num2) taken from Twitter, to better classify tweets. The results obtained demonstrate that our model performed well regarding different metrics based on the confusion matrix including the accuracy metric, which achieved 87. 23% on the first dataset, and 93. 06% on the second.

Learner’ school violence using incident logbook: a qualitative research approach

In this paper the notion of leaner’s school is revisited using a silent tool, incident logbook. Research shows that incidents of learner violence has escalated in South Africa unabated. Different approaches to describe and recommend strategies to alleviate cases of violence in schools have been undertaken. This paper aims to describe through incident logbook learner’s behaviour regarded as serious misconducts that involve violent acts. These violent acts might lead to expulsion or suspension of a learner from the school according to the South African Schools Act, 1996 and various school policies. Am interpretivist qualitative research was employed using a purposively sample of 5 incidents logbooks from five secondary schools. The researchers used a thematic data analysis using a Critical Peace Education (CPE) theory to discuss these incidents of school violence. The findings of the study show high incidents of recorded serious misconduct and violations of the school policies by learners by committing, violent acts such as physical, psychological, emotional abuses as well as thefts and vandalism of school and personal property. The research study recommends that CPE be used as tool to educate and foster peaceful co-existence in schools.

Frontline Response to High Impact Domestic Violence in Austria

The networked response to cases of high-impact domestic violence in Austria predominantly involves four groups of actors, who share both formal and informal modes of inter-agency cooperation, and each function as independent entry points to a networked intervention. These groups consist of specialised and non-specialised police officers, a number of NGOs in the social sector, regional administration and municipal authorities, as well as the medical sector, predominantly involving hospital staff. The most important legal measure in place for the protection of victims by police is the restraining order in the Security Police Act, which was introduced as part of the victim protection guidelines. A unified and universally applied definition of domestic violence does not exist in Austria. As a result, there is no cross-sectoral standardisation when identifying violent acts. Nevertheless, the networked response in Austria is characterized by a robust system of inter-agency referrals and formalized cooperation.

Becoming a Man

This paper seeks to analyze the affective-sexual trajectories of young gay men in Rio de Janeiro, Brazil. Based on qualitative research with 15 young, urban, low-income gay men aged between 19 and 24, carried out in 2019, this article shows the learning of masculinity and its consequences on the men’s sex lives. As a result, we argue that these young men have been brought up for the exaltation of heterosexuality and being a real man since boyhood; that the pedagogies of masculinity produce hierarchies among gay masculinities; and that the connection with other social markers, such as race, social class, religion, sexual preferences related to being active or passive, and gender expressions, upholds the notion of hegemonic masculinity. Regarding those who escape this pattern, these young men reveal several vulnerabilities and multiple violent acts during their trajectories.

VIOLENT ACTS AGAINST HEALTHCARE INSTITUTIONS AND WORKERS IN HUNGARY

Povzetek Namen te presečne kvantitativne raziskave je ugotoviti, katera oblika nasilja je v madžarskih zdravstvenih ustanovah najpogostejša. Z njo želimo oceniti, ali se v teh ustanovah izvaja usposabljanje za komunikacijo, simulacijo in samoobrambo. Cilj je ugotoviti, ali bi se zaposleni udeležili takega usposabljanja, ter oceniti povezanost med usposobljenostjo (komunikacija, simulacija, samoobramba) in stopnjo samozavesti. Žrtve večine nasilnih dejanj pacientov so zdravstveni delavci. Najpogostejša oblika agresije pacientov in njihovih svojcev je verbalna agresija, vključno z zbadanjem, verbalno zlorabo in grožnjami z zlorabo. Podatki kažejo, da zgolj usposabljanje v komunikaciji ni dovolj za dvig samozavesti pri zdravstvenih delavcih. Treba jim je zagotoviti orodje, kot so na primer praktične vaje po usposabljanju iz samoobrambe ali simulacija, saj to olajša komunikacijo zaposlenega. Ključne besede Agresija, zdravstvo, preventiva, usposabljanje, samoobramba, samozavest. Abstract The present cross-sectional quantitative research aims to gain a sense of which form of violence is the most common in Hungarian healthcare institutions. It aims to assess whether communication, simulation, and self-defence training is provided in institutions, to find out whether workers would participate in such training, and to assess the relationship between training (communication, simulation, self-defence) and confidence. Healthcare workers are affected by most acts of violence coming from patients. The most common type of aggression on the part of patients and relatives is verbal aggression, including teasing, verbal abuse, and threats of abuse. The data show that communication training alone is not enough to make health workers confident. They should have a tool in their hands, e.g., practice after self-defence education, simulation practice, as this makes it easier for the employee to communicate. Key words Aggression, healthcare, prevention, training, self-defence, confidence.

CLINICAL AND SOCIAL FACTORS ASSOCIATED WITH VIOLENT BEHAVIOR IN PERSONS WITH SCHIZOPHRENIA SPECTRUM DISORDERS

Study of the relationship between mental disorder and violent behavior is critical both from a public health perspective and for the proper planning and development of mental health services.However, the complex contribution of clinical, historical and environmental risk factors for violence in persons with schizophrenia remains unclear. The aim of the study was to identify clinical and social risk factors for violence in patients with schizophrenia and schizophrenia spectrum disorders (SSD) using a case-control design. Cases were defined as patients with SSD who had committed at least one act of offence in the past (94 patients wereenrolled from forensic psychiatricward). Controls were genderand age matched patients with SSD who had never committed violent acts (106 patients from general psychiatric services).A standard set of instruments was used to assess patients exposure to a variety of risk factors. Data were collected through patient interviews and medical records.Study results showed, that increased risk of violence was associated with severity of positive psychotic symptoms, diagnosis of delusional disorder, irregular or no contacts with mental health services. Significant risk factors for serious violent acts were associated with comorbid alcohol misuse, impulsivity,persecutory delusions,decreased emotional responseand unsatisfactory living environment. Study confirmed that the interaction of social andclinicalfactorswith treatment related factors played an important role as determinants of violence. These factors should be the focus of treatment and management of patients with SSD to prevent violent behavior.

Exploring the instrumental and reactive violence dichotomy in the offences of violent psychopaths

<p>In the literature acts of violence are often divided into two dichotomous subtypes: instrumental and reactive violence. The two types of violence are considered to be underpinned by different theoretical paradigms, social learning theory and frustration aggression. This division, although widely criticised and lacking conceptual clarity, appears to be generally accepted in scientific literature. This exploratory study used multidimensional scaling and cluster analysis to see how violence characteristics co-occur in the offences of seriously violent psychopathic offenders; and whether the co-occurrence of offence variables could be explained by the instrumental and reactive dichotomy. The study also explored whether instrumental and reactive violence characteristics differentiate primary and secondary variants of psychopathy, with the hypotheses that primary psychopaths would show more instrumental features in their violence and secondary psychopaths show more reactive features. Findings show that violence characteristics do no co-occur as a mutually exclusive dichotomy and that rather, many violent acts have mix of reactive and instrumental characteristics, reflecting a dimensional rather than a dichotomous structure. This in turn suggests that act specific theories may not be necessary to describe different types of violence. Contrary to prediction, psychopathic subtypes did not differ on violence characteristics.</p>

Interreligious dialogue and socio-religious dialogue in today's society

Today's society needs to organise interreligious and socio-religious dialogues in order manage to work effectively for finding a form of concord between peoples, so that no more unfortunate events such as terrorist attacks and other violent acts occur. One of the solutions is given by the interreligious dialogue carried out worldwide, a dialogue from which the participants, although having different traditions and cultures, can draw points of common interest, so that peace becomes a natural conclusion of the latter.
