In this study three chronicles from national newspapers (one generalist and two sport press) were analyzed. The chronicles belong to Spain’s soccer final of the King’s Cup in 2014. The aim of the study was to know if there was any influence on the readers’ perception of justice and consequently if this influence could cause a particular predisposition to participate in acts of protest. 462 university students participated. The results showed that different chronicles caused differences in the perception of justice depending on the chronicle read. However, a clear influence on the willingness to participate in acts of protest was not obtained. These results should make us think about the impact of sport press and its influence, and to be aware of the indirect responsibility of every sector on the antisocial behaviors generated by soccer in our country.

Entre las actividades de ocio de los/as jóvenes, cabe mencionar las asociadas con los videojuegos. Por ello, la finalidad central de este estudio es analizar las preferencias del colectivo de adolescentes con los videojuegos, así como conocer su dedicación y problemáticas que generan, teniendo en cuenta principalmente la variable de género. El presente trabajo se encuadra en un enfoque metodológico cuantitativo-cualitativo, a partir de la recogida de datos con un cuestionario y la técnica del grupo de discusión. En el estudio han participado un total de 151 adolescentes. 124 a partir de la aplicación de un cuestionario cerrado (62 hombres y 62 mujeres) y 27 a través de la realización de 6 grupos de discusión (17 hombres y 10 mujeres). Como resultados y conclusiones, cabe destacar la existencia diferenciada en el uso de los videojuegos en función de la edad y por razón de género. A su vez, las mujeres muestran una responsabilidad mayor en esta actividad, tanto en el tiempo de dedicación como en la elección. Los chicos destinan una gran cantidad de tiempo a los videojuegos de contenido violento, mientras las chicas prefieren los de estrategia. En general, el juego con videojuegos no genera problemáticas sustanciales y controversias, aunque algunos participantes reflejan manifestaciones de mal humor. Por último, cabe indicar que las prácticas con los videojuegos en la adolescencia se ciñen al mero hecho de divertirse, desperdiciando las posibilidades educativas que esta actividad ofrece.

This paper is a part of a larger research that pursues a global understanding of impoliteness in face-to-face electoral debates. That research distinguishes three essential axes, three complementary analytical perspectives: functional strategies of impoliteness, linguistic-discursive mechanisms to implement them and social impacts of impolite acts. In this frame, the present work develops an in-depth analysis of a special category of mechanisms, namely the rupture of politeness conventions, a subgroup within postliteral implicit mechanisms. This subgroup acquires its identity by the fact of carrying out a linguistic action that is conventionally associated with a polite attitude, but doing it in a rhetorically insincere way: the consequence is that apparent politeness becomes impoliteness. Relevant aspects in the characterization of ruptures are isolated and, on this basis, it is developed a detailed analysis of three specific kinds of mechanisms in which ruptures take shape: using ironic statements, developing different forms of overpoliteness and adopting a falsely collaborative attitude toward the interlocutor. The analysis of that group of mechanisms takes into account, simultaneously, the other two axes of the main research, strategies and social impacts.

Displays are a feature of animal contest behaviour and have been interpreted as a means of gathering information on opponent fighting ability, as well as signalling aggressive motivation. In fish, contest displays often include frontal and lateral elements, which in the latter involves contestants showing their flanks to an opponent. Previous work in a range of fish species has demonstrated population-level lateralization of these displays, preferentially showing one side to their opponent. Mirrors are commonly used in place of a real opponent to study aggression in fish, yet they may disrupt the normal pattern of display behaviour. Here, using Siamese fighting fish, Betta splendens, we compare the aggressive behaviour of males to a mirror image and real opponent behind a transparent barrier. As this species is a facultative air-breather, we also quantify surface breathing, providing insights into underlying fight motivation. Consistent with previous work, we found evidence of population-level
lateralization, with a bias to present the left side and use the left eye when facing a real opponent. Contrary to expectations, there were no differences in the aggressive displays to a mirror and real opponent, with positive correlations between the behaviour in the two scenarios. However, there were important differences in surface breathing, which was more frequent and of longer duration in the mirror treatment. The reasons for these differences are discussed in relation to the repertoire of contest behaviour and motivation when facing a real opponent.

There is increasing interest in the use of continuous housing systems for dairy cows, with various reasons put forward to advocate such systems. However, the welfare of dairy cows is typically perceived to be better within pasture-based systems, although such judgements are often not scientifically based. The aim of this review was to interrogate the existing scientific literature to compare the welfare, including health, of dairy cows in continuously housed and pasture-based systems. While summarising existing work, knowledge gaps and directions for future research are also identified. The scope of the review is broad, examining relevant topics under three main headings; health, behaviour, and physiology. Regarding health, cows on pasture-based systems had lower levels of lameness, hoof pathologies, hock lesions, mastitis, uterine disease, and mortality compared to cows on continuously housed systems. Pasture access also had benefits for dairy cow behaviour, in terms of grazing, improved lying / resting times, and lower levels of aggression. Moreover, when given the choice between pasture and indoor housing, cows showed an overall preference for pasture, particularly at night. However, the review highlighted the need for a deeper understanding of cow preference and behaviour. Potential areas for concern within pasture-based systems included physiological indicators of more severe negative energy balance, and in some situations, the potential for compromised welfare with exposure to unpredictable weather conditions. In summary, the results from this review highlight that there remain considerable animal welfare benefits from incorporating pasture access into dairy production systems.

Background. Individual trajectories toward aggression originate in early infancy, before there is intent to harm. We focused on infants who were contentious, i.e., prone to engage in anger and use of physical force with other people, and examined change in levels of contentiousness between 6 and 12 months of age with reference to later aggressive conduct problems.
Sample. The CCDS is a nationally representative sample of 321 firstborn children whose families were recruited from antenatal clinics in two National Health Service Trusts.
Method. Mothers, fathers, and a third family member or friend who knew infants well completed the Cardiff Infant Contentiousness Scale (CICS) at 6 months, which was stable form 6 to 12 months, and validated by direct observation of infants’ use of force against peers. Primary caregivers again completed the CICS at 12 months, and up to three informants completed the Child Behaviour Check List at mean ages of 36 and 84 months. We used Latent Transition Analysis to identify different groups of infants in respect to their patterns of contentiousness from 6 to 12 months.
Results
Three ordered classes of contentiousness from low to high were found at 6 and 12 months. Infants exposed to greater family adversity were more likely to move into the high-contentious class from 6 to 12 months. Higher contentiousness in infancy predicted more aggressive conduct problems at 33 months and thereafter.
Conclusions
Infants exposed to family adversity are already at disadvantage by 6 months and likely to escalate in their anger and aggressiveness over time.

Germany, Italy and Japan were engaged in China from the turn of the 20th century to WWII. However, they formed an anti-Chinese alliance only at the final stage of their presence there, when Japan assumed an undisputed role of leader in the region. Despite its alliance with the Axis powers, Japan never implemented racial laws against the Jews in China. All of them took part in the Boxer Upraising suppression and received as a consequence extraterritorial rights and concessions. Moreover, Japan won the war against China in 1895 and transformed itself from a tributary country of China into an imperialistic power. It took possession of Taiwan and in the 1930s established a puppet government in Manchuria.Germany followed different route obtaining as indemnity for the murders of two missionaries the control of the Shandong province, which was later expanded thanks to the anti-Boxer coalition's victory. However, Germany lost all possessions when China entered WWI. The issue of Shandong was finally resolved at the Conference for Disarmament hold in Washington in 1921-2. Japan failed to gain ex-Germany territories. Finally, Italy arrived in the Far East at the turn of the century but was not very interested in the oriental colonialism to the same extent it was interested in Africa. Tianjin was its only concession in China, and it took almost a decade before a subvention to arrive from the Italian government for its development.In the 1920s and 1930s Germany and Italy engaged in successful diplomatic, commercial and military relationships with China. In fact, both were considered China's partners thanks to their experts at the service of the Chinese government. On the other hand, Japan position was opposite to them, because of its plans of aggression towards China which was to be transformed into “the natural extension” of the mainland. In 1935 Italy declared war on Ethiopia and abandoned the seat at the League of Nations. China interpreted the Italian aggression as the endorsement of Japan's politics towards China in Manchuria, and the relations between the two countries were broken off. After that Italy supported Wang Jingwei's puppet government during the Japanese occupation of China. Germany followed the same path in 1937, when it was evident that the Japanese were playing the leading role in the region, and decided to ally with Wang Jingwei too. Both Italy and Germany decided also to recognise the Manzhuguo and established diplomatic relations, definitively turning their backs on the old Chinese ally.The Rome-Berlin-Tokyo Axis sealed the alliance among the three countries, and it confirmed Japan as the leading power in the region. Nevertheless Japan did not apply the racial law against the Jews in China.

As an enduring legacy of the conflict, paramilitary policing remains an unpalatable but indisputable fact within Belfast's working-class, Republican communities. Historically, while much attention has been devoted to the causes and consequences of paramilitarism along with the terrorist threat posed by such organizations, little attention has been paid to the influence upon, or relations between, such nonstate policing actors, the communities in which they exist and the delivery of policing by the Police Service of Northern Ireland. While local and international literature surrounding paramilitary violence has tended towards political axiom or physical impact of such activity, the current paper presents an empirical study of the relations between communities and Republican paramilitary organizations who seek to exploit a perceived dearth of state-based policing at the community level within Belfast. Framing the ontology of paramilitary policing and its support from a community, rather than political or security perspective, the paper argues that continuing grass-roots support for this ‘new’ paramilitary policing within Republican communities of Belfast is more complex and nuanced than the political antecedents of the conflict from which such activity emerged – especially in terms of such support surviving successive political negotiations and police reforms since the ‘Good Friday’ Agreement of 1998.

Animal contests vary greatly in behavioural tactics used and intensity reached, with some encounters resolved without physical contact while others escalate to damaging fighting. However, the reasons for such variation remains to be fully explained. Aggressiveness, in terms of a personality trait, offers a potentially important source of variation that has typically been overlooked. Therefore, we studied how aggressiveness as a personality trait influenced escalation between contestants matched for resource holding potential (RHP), using detailed observations of the contest behaviour, contest dynamics, and escalation levels. We predicted that winner and loser behaviour would differ depending on personality. This was tested by examining 52 dyadic contests between pigs (Sus scrofa). Aggressiveness was assayed in resident-intruder tests prior to the contest. Contests were then staged between pigs matched for RHP in terms of body weight but differing in their aggressiveness. In 27% of the contests a winner emerged without escalated physical fighting, demonstrating that a fight is not a prerequisite between RHP-matched contestants. However, the duration of contests with or without fighting was the same. In contests without a fight, opponents spent more time on mutual investigation and non-contact displays such as parallel walking, which suggests that ritualized display may facilitate assessment and decision making. Winners low in aggressiveness invested more time in opponent investigation and display and showed substantially less aggression towards the loser after its retreat compared to aggressive winners. Aggressiveness influenced contest dynamics but did not predict the level of escalation. Prominent behavioural differences were found for the interaction between personality and outcome and we therefore recommend including this interaction in models where personality is considered. Analyses based on contest duration only would miss many of the subtleties which are shown here and we therefore encourage more detailed analyses of animal contests, irrespective of the level of contest escalation.

Bakgrund: Alzheimers sjukdom (AD) är den vanligaste formen av demenssjukdomar och antalet människor som insjuknar i AD förväntas öka kraftigt med tiden. Dessutom kännetecknas personer med AD ofta av beteendemässiga och psykiska symtom (BPSD) som kan innefatta agitation, depression, vanföreställningar, oro, ångest, hallucinationer, sömnrubbningar, rastlöshet och apati. Dessa symtom kan orsaka lidande hos patienten och är svåra att hantera för både vårdgivaren och anhöriga, samt försvårar omvårdnadsarbetet. Syftet var att beskriva icke-farmakologiska metoder och effekter av dessa metoder vid omvårdnad av personer med Alzheimers sjukdom som har beteendemässiga och psykiska symtom. Metod: En litteraturöversikt bestående av 16 utvalda kvantitativa forskningsartiklar har genomförts. Artiklarna publicerades mellan år 2006-2016. Resultat. De studerade icke-farmakologiska metoderna var musikterapi, vissa typer av massage, reminiscence-terapi, vårdhundterapi och ljusterapi. Resultaten visade att icke-farmakologiska metoder kan ha en varierande effekt på BPSD. Litteraturöversikten visade att musikintervention var mest effektiv för att minska agitationsbeteende. Individualiserad musik i samband med speciella minnen minskade stress, fobier hos personer med svår demens. Intervention av handmassage, aromaterapi, taktil massage och terapeutisk beröring minskade aggression och agitationsbeteende. Vissa studier visade dock att fotmassageintervention och vårdhundterapi kunde öka verbal aggressivitet hos personer med demens, medan en annan studie visade att djurassisterade aktiviteter kunde minska nedstämdhet medan glädje och generell uppmärksamhet ökade. Effekten av ljusbehandling var förbättrad sömn, minskad depression, agitation och ätstörningar. Slutsats. Icke-farmakologiska metoder kan minska beteendemässiga och psykiska symtom hos personer med Alzheimers sjukdom, dock med varierande effekt. De varierande resultaten kan tolkas som att icke-farmakologiska metoder bör individanpassas och att det behövs vidare forskning inom området.

Alguns estudos foram feitos no sentido de verificar a relação entre os traços de personalidade e a agressividade (e.g.Tyrode & Bourcet, 2002). Jean Pinatel (1987) foi um dos autores que definiu traços comuns de personalidade que se encontram frequentemente nos indivíduos delinquentes. Tais traços são: o egocentrismo, a labilidade, a agressividade e a indiferença afectiva. Contestando esta noção dos traços de personalidade, outros autores (e. g. Gibert & Daffer , 2011) defendem que o comportamento agressivo é entendido como resultado de uma série de experiências que levam o indivíduo a comportar-se de forma agressiva em situações diferentes. Esta investigação teve como objectivo estudar a relação entre a personalidade e a agressividade numa amostra de adolescentes e jovens adultos que moram em alguns bairros sociais da área de Lisboa, bem como contribuir para uma maior compreensão destas variáveis, nomeadamente a sua relação com as variáveis género, idade e escolaridade. Assim, a amostra foi constituída por 150 participantes, de ambos os sexos, com idades compreendidas entre os 15 e os 29 anos. Para avaliar as variáveis foram utilizadas as seguintes escalas: Big Five Inventory (BFI; Benet-Martínez & John, 1998) para medir a Personalidade e Aggression Questionnaire (AQ; Buss & Perry, 1992) para a Agressividade. Tendo em conta os principais dados teóricos sobre essas variáveis, espera-se que: 1) Os traços de personalidade dos adolescentes e jovens adultos se correlacionem de forma significativa com a agressividade; 2) Os participantes do sexo masculino apresentem valores diferentes nos traços de personalidade e na agressividade relativamente aos participantes do sexo feminino; 3) A idade se correlacione de forma significativa com as dimensões da personalidade e da agressividade nos adolescentes e jovens adultos; 4) A escolaridade se correlacione significativamente com as dimensões da personalidade e da agressividade nos adolescentes e jovens adultos. Concluiu-se que a Agradabilidade se correlaciona significativamente com a Agressividade Física e com a Agressividade Total, indicando que quanto maior a Agradabilidade menor a agressividade. Verificou-se que os rapazes e as raparigas apresentaram maiores diferenças na Agradabilidade e na Agressividade Física. A idade não apresentou correlações significativas com a agressividade, no entanto correlacionou-se de forma significativa com a Conscienciosidade e a Abertura à Experiência. E a escolaridade, por sua vez, apresentou correlações significativas com a Abertura à experiência, a Agressividade Física, a Hostilidade e a Agressividade Total.

Objectivos: O presente estudo tem como principal objectivo avaliar a prevalência dos comportamentos de cyberbullying, analisando a influência de variáveis sóciodemográficas, e, compreender a sua relação com as vivências de vergonha interna e externa e com os estados emocionais negativos, particularmente a depressão, a ansiedade e o stress. Método: Para a recolha de dados recorreu-se a uma mostra de adolescentes (N=131) a frequentar o 3º ciclo do ensino básico, com idades compreendidas entre os 12 e os 18 anos (M= 13,76; DP= 1,25). O protocolo de avaliação foi constituído por um questionário psicossocial desenvolvido especificamente para este estudo e por um conjunto de medidas fidedignas para avaliar o cyberbullying (CBQ e CBQ-V), a vergonha interna (ISS), vergonha externa (OAS) e os estados emocionais negativos (DASS-21). Resultados: Os nossos dados revelaram que 76 adolescentes (58%) exerceram um qualquer comportamento de cyberbullying (com um predomínio dos rapazes), enquanto 50 adolescentes (38,2%) já foram vítimas de um qualquer comportamento de cyberbullying (com igual proporção entre rapazes e raparigas). Manter lutas e discussões online, usando insultos mediante mensagens electrónicas foi o comportamento praticado mais frequente (30,5%), enquanto o ser removido intencionalmente de um grupo online foi o comportamento sofrido mais frequente (16,1%). A idade e os anos de reprovações mostraram uma associação positiva com os comportamentos de agressão por cyberbullying. Foi ainda analisada a sobreposição entre a execução e a vitimização de comportamentos de cyberbullying, tendo sido discriminados quatro grupos de adolescentes: só agressores (adolescentes que apenas exerceram comportamentos de agressão), só vítimas (apenas sofreram comportamentos de cyberbulling), vítimas e agressores (adolescentes que são simultaneamente agressores e vítimas), e nem vítimas nem agressores (adolescentes que não exerceram nem sofreram qualquer comportamento de cyberbullying). Os resultados evidenciaram que quanto maior a frequência de comportamentos de agressão por cyberbullying, maior a vergonha interna e maior os níveis de stress demonstrados. Por sua vez, quanto maior a frequência de vitimização por cyberbullying, maior a vergonha interna e externa, bem como maior os níveis de ansiedade e stress. Conclusão: Devido a complexidade do fenómeno cyberbullying e seu recente surgimento, serão necessários mais estudos, particularmente longitudinais, para compreender a relação antecedente e/ou consequentes aos comportamentos de cyberbullying entre estados emocionais negativos e as experiências de vergonha. / Objectives: The present study has as main objective to assess the prevalence of cyberbullying behaviours, analyzing the influence of socio demographic variables, and, understand its relationship to the experiences of internal and external shame and negative emotional states, particularly depression, anxiety and stress. Method: For data collection we used a sample of adolescents (N=131) attending the 3rd cycle of basic education, aged between 12 and 18 years (M=13,76; SD=1,25). The evaluation protocol consisted of a psychosocial questionnaire developed specifically for this study and a set of reliable measure to assess cyberbullying (CBQ and CBQ-V), internal shame (ISS), external shame (OAS) and the emotional states negative (DASS-21). Results: Our data indicate that 76 adolescents (58%) exerted any conduct of a cyberbullying (with a predominance of boys), while 50 adolescents (38,2%) had been victims of cyberbullying behaviour of any one (with an equal ratio of boys and girls). Keep fighting and discussions online, through e-mails using insults behaviour was practiced more often (30,5%), while being intentionally removed a group of online behaviour is seen more frequently (16,1%). The age and years of failures were positively associated with the behaviours of aggression by cyberbullying. Was further examined the overlap between enforcement and victimization of cyberbullying behaviours, having been discriminated four groups of adolescents: only aggressors (adolescents who have had only aggressive behaviour), only victims (only suffered cyberbullying behaviours), victims and aggressors (adolescents who are both perpetrators and victims), and neither victims nor aggressors (adolescents who did not exercise any behaviour or suffered cyberbullying). Results showed that the higher the frequency of aggression by cyberbullying behaviour, the greater shame and internal stress levels demonstrated. In turn, the higher the frequency of cyberbullying victimization, the greater the shame internal and external, as well as higher levels of anxiety and stress. Conclusion: Due to the complexity of the phenomenon cyberbullying and its recent emergence, further studies are needed, particularly longitudinal, to understand the relationship between antecedent and/or consequential to cyberbullying behaviours between negative emotional states and experiences of shame.

Objetivos: Este estudo tem como objetivo analisar as representações da Mulher no discurso científico, em particular nas Ciências Sociais e do Comportamento. Metodologia: Optámos por um estudo de caso com uma abordagem metodológica de análise de conteúdo qualitativa, com recursos a informações quantitativas utilizando o software informático MAXQDA 12. A análise foi desenvolvida a partir de uma grelha de categorização que delineámos. Amostra: A nossa amostra é composta por um conjunto de 122 artigos publicados em 9 revistas científicas portuguesas na área da Psicologia no ano de 2015. Resultados: Atráves da análise dos 122 artigos, no conjunto das 9 revistas, obtivemos uma predominência da categoria “Família”, seguida do “Género” e por posteriormente da “Agressão”. Em comparação com o número de artigos em que as categorias estão presentes, obtivemos algumas diferenças. A categoria “Família” é a mais frequente, depois “Feminino” e por fim a “Agressão”, sendo estas também as que tiveram em destaque em maior parte das revistas analisadas. Verificámos que em algumas revistas havia mais que uma categoria prevalecente. Destacamos também que mais de metade das categorias não revelaram predominância nem relevância ao longo do estudo. Conclusão: O dicurso em relação à Mulher nos estudo científicos das Ciências Sociais e do Comportamento continua a manter-se ligado às representações sociais tradicionais, associadas à família e ao feminino. Não verificámos uma verdadeira transformação nos Estudo da Mulher, mas antes um eco de outros discursos e representações societariamente aceites. / Objectives: This study aimed to analyse the representations of Women in scientific discourse, particularly in Social and Behavioural Sciences. Methodology: We developed a case study using a methodological approach with qualitative content analysis, with resources to quantitative information using computer software MAXQDA 12. The analysis was developed from a grid of categorization that we outlined. Sample: Our sample is composed of a set of 122 articles published in 9 Portuguese scientific journals in Psychology in 2015. Results: Through the analysis of 122 articles in the nine journals, we obtained a relevance of the "Family" category, followed by "Gender" and "Aggression". Comparing the number of articles in which the categories are present, we found some differences. "Family" is the most frequent, followed by "Female" and "Aggression", which are also the categories that were highlighted in most of the journals analysed. We found that in some journals had more than a prevailing category. We also note that more than half of the categories did not show dominance or relevance throughout the study. Conclusions: The discourse on women in scientific studies of Social and Behavioural Sciences continues to remain linked to traditional social representations associated with the family and the female. We not noticed a real change in the Women's Study, but an echo of other speeches and corporate aspects accepted representations.
