Human sexuality touches us all, pun intended. We all either enjoy it, struggle with it, or may have been victims of it. Sexuality is not just about sex, but about human sexual function, the physiology of sex, the hormones involved and how they affect us, and the cultural norms related to it. Sexual function and dysfunction are closely tied to one's self-esteem, self-respect, and to relationships with intimate partners. Human Sexuality: Function, Dysfunction, Paraphilias, and Relationships, explores the interplay of intimacy and sexuality; how it can enhance relationships, and how it can negatively affect them, or be affected by them. When individuals or partners encounter sexual problems or dysfunctions it can have a long-lasting affect both biologically and psychologically. Dr. Rokach explores the causes and the reasons that these dysfunctions are maintained, and successful treatment methods. Chapters on sexual offenses and paraphilias and what treatment options are available to sexual offenders are also included. This book is the first book to place sexuality where it belongs, within the context of relationships demonstrating how sexuality relates to intimacy by both enhancing and negatively affecting it.

'There is no doubt a greater awareness now of the significance of twin loss than there was ten years ago. I think that this is largely due to a big increase in articles, radio and television programmes as well as the spread of the Network. The well-known researcher Nancy Segal in the USA has, through her many books, added knowledge to our understanding of twin relationships as well as twin loss. She believes the loss to be highly significant and queries whether for some lone twins it is greater even than that of the loss of a spouse (Segal 2000). Others have written autobiographical material about their loss (Jones 1987; Farmer 1988). In spite of this, there is still ignorance. At a recent book launch for the publication of a book about the loss of a twin through drug taking (Burton-Phillips 2007) someone in the field of education said to a few of us from the Network, that she did not see how a twin who lost their twin at birth could possibly be affected. She asked, 'How would the surviving twin know?' I asked her to imagine how she might feel if told during her childhood that she had been born a twin, but due to her taking all the food' during the pregnancy, her twin had not survived. I suggested that perhaps worse, she might have had her parents make it clear that they wished her twin had been the one to live. Less dramatically, she was asked how she might feel missing someone all her life who 'should have been there' to share it. This question was put by a lone twin who added that she had also had surviving twins born to the family to watch growing up as a pair, while she was without her twin sister. The educationist was honest and said she had never thought of those things before and then freely admitted our comments made her think again' - Joan Woodward, Author.

The physical effects of COVID-19 are felt globally. However, one issue that has not been sufficiently addressed is the impact of COVID-19 on mental health. During the COVID-19 pandemic, citizens worldwide are enduring widespread lockdowns; children are out of school; and millions have lost their jobs, which has caused anxiety, depression, insomnia, and distress. Mental Health Effects of COVID-19 provides a comprehensive analysis of mental health problems resulting from COVID-19, including depression, suicidal thoughts and attempts, trauma, and PTSD. The book includes chapters detailing the impact of COVID-19 on the family's well-being and society dynamics. The book concludes with an explanation on how meditation and online treatment methods can be used to combat the effects on mental health.

This book presents procedures and research techniques that are based on critical perspectives of Psychology and Education. The content is characterized by innovations on the relationship between the researcher and the investigated context, and it problematizes different perspectives and approaches to the psychological phenomenon proposing new understandings of the subject, the world, the social and the field of investigation itself as a permanent dialectical movement. The book reports to Marxist-based perspectives - especially to Vygotsky's ideas and concepts. Therefore, it assumes the comprehension that in order to understand the phenomenon in its historical dimension it is necessary to put it into motion seeking to access the genesis of the manifestations evidenced at the moment of the investigation. That is, the historicity that characterizes the process of constitution of the human psyche can only be apprehended in its movement, thus, what matters is the process and not the product of its development. Nevertheless, apprehending phenomena in movement is a challenge for researchers interested in human processes within the scope of relationships or practices of professionals and/or subjects of various scenarios, which leads to the need to problematize the different moments of research and their dimension in the theoretical and practical fields. Which methodological techniques or procedures allow the apprehension of the meaning movement produced by the subjects in the investigated scenarios? To what extent does dialectical materialism derived from Marxism support the apprehension and analysis of research information of this nature? What other theoretical-methodological perspectives, related to Cultural-Historical Psychology, offer subsidies to these investigations? The theoretical perspectives based on the Social and Cultural analysis focus on the understandings of collective contexts precisely because of the subject view constituted in the inter-subjective relations that it undertakes - which adds even more complexity to the investigative processes. From this perspective, both the subject and other participants transform themselves during the investigation, such transformation needs to be permanently reflected and included in the research objectives and purposes, in order to follow the movement of the meanings in the expressed phenomenon.
