RESUMO
In the discussion about zoo elephant husbandry, the report of Clubb et al. (2008, Science 322: 1649) that zoo elephants had a "compromised survivorship" compared to certain non-zoo populations is a grave argument, and was possibly one of the triggers of a large variety of investigations into zoo elephant welfare, and changes in zoo elephant management. A side observation of that report was that whereas survivorship in African elephants (Loxodonta africana) improved since 1960, this was not the case in Asian elephants (Elephas maximus). We used historical data (based on the Species360 database) to revisit this aspect, including recent developments since 2008. Assessing the North American and European populations from 1910 until today, there were significant improvements of adult (≥10 years) survivorship in both species. For the period from 1960 until today, survivorship improvement was significant for African elephants and close to a significant improvement in Asian elephants; Asian elephants generally had a higher survivorship than Africans. Juvenile (<10 years) survivorship did not change significantly since 1960 and was higher in African elephants, most likely due to the effect of elephant herpes virus on Asian elephants. Current zoo elephant survivorship is higher than some, and lower than some other non-zoo populations. We discuss that in our view, the shape of the survivorship curve, and its change over time, are more relevant than comparisons with specific populations. Zoo elephant survivorship should be monitored continuously, and the expectation of a continuous trend towards improvement should be met.

The growing availability of digital technologies has led to increased rates of using them as a part of daily recreational activity among adolescents. Despite their positive effects, there are ongoing debates of potential harm and health-related negative consequences, particularly when internet activities are performed excessively. This contribution provides an overview on negative aspects of digital technologies by presenting a selection of empirical findings. This overview focuses on a selection of recent methodologically sound studies investigating potential negative effects of digital technologies on the development of adolescents. As main constructs, effects on psychosocial and cognitive development and internet use disorders were investigated. Recently published studies point to substantial associations between internet overuse and negative consequences. Habitual, intense use of the internet is related to higher rates of internalizing symptoms, cognitive distortions, and heightened rates of internet use disorders among adolescents. Given these findings it seems recommendable to provide a close parental monitoring of adolescents discovering virtual worlds. By applying clear rules and supporting development of media literacy, functional use habits can be empowered and harmful effects prevented.The new clinical phenomenon of internet use disorder and its high prevalence among adolescents represents a new challenge for treatment services.

BACKGROUND: Research over the past years has shown that exposure to thin and beauty ideals in the media can be associated with disordered eating and related variables. Nowadays, interactive media, such as social networking sites, have gained growing popularity and represent a major part of people's lives. It is therefore crucial to investigate how far users might be negatively influenced by social networking sites regarding eating pathology or excessive exercise behavior and if there are particular links to social media use disorder. METHODS: Data were collected by an online-survey encompassing questions on regular social networking site use, eating disorders, and excessive exercise behavior. RESULTS: Analyses showed that disordered social networking sites use was significantly related to eating pathology and a poorer body image in men and women. The frequency of active or passive social networking sites usage however was not associated with exercise behavior. CONCLUSIONS: Our results confirm that disordered social networking sites use represents a risk factor for body image dissatisfaction and associated eating disorders.

Social media disorder (SMD) is a frequently occurring subtype of Internet-related disorders (IRD), which has recently become a focus of research. It is noticeable that women are among those affected, whose nosological characteristics need to be examined. A clinical sample of n = 294 women (14-68 years, M = 36.88 years) was generated. The questionnaire included questions about demography, IRD, SMD, personality traits, psychopathological distress, functional impairment and comorbid mental illnesses. IRD was found in 17.5 percent and SMD in 12.5 percent of women. Compared to women with global IRD Women with SMD reported lower scores on the personality traits neuroticism and agreeableness. They are more frequently functionally impaired in the social dimension, more often reported comorbid substance-dependency and less eating disorders. The results suggest that although have similar characteristics to the comparison group, women with SMD differ in their nosological characteristics from women with global IRD.

OBJECTIVE: Internet-related disorders (IRD) are characterized by uncontrolled use of various Internet applications, which is associated with impairments in various sections and an increased rate of other forms of mental illness. The aim was to identify undiagnosed comorbid IRD and to examine gender-specific differences. METHODS: In 19 psychotherapeutic institutions 501 patients (65.3â% women) were recruited. RESULTS: Comorbid IRD was found in 20.7â% of men and 15.9â% of women. IBS was not identified by the practitioners in 94.6â% of women and 66.6â% of men. In particular affective disorders and substance-related addiction occurred very frequently and regardless of gender. Women were significantly more often affected by eating and personality disorders, men were significantly more often affected by pathological gambling. CONCLUSION: A high rate of IBS remains undetected in the psychotherapeutic care system. Women with IBS have other referral diagnoses and are more often affected by severe mental disorders than men.
