Plants in the family Lemnaceae are aquatic monocots and the smallest, simplest, and fastest growing angiosperms. Their small size, the smallest family member is 0.5 mm and the largest is 2.0 cm, as well as their diverse morphologies make these plants ideal for laboratory studies. Their rapid growth rate is partially due to the family’s neotenous lifestyle, where instead of maturing and producing flowers, the plants remain in a juvenile state and continuously bud asexually. Maturation and flowering in the wild are rare in most family members. To promote further research on these unique plants, we have optimized laboratory flowering protocols for 3 of the 5 genera: Spirodela; Lemna; and Wolffia in the Lemnaceae. Duckweeds were widely used in the past for research on flowering, hormone and amino acid biosynthesis, the photosynthetic apparatus, and phytoremediation due to their aqueous lifestyle and ease of aseptic culture. There is a recent renaissance in interest in growing these plants as non-lignified biomass sources for fuel production, and as a resource-efficient complete protein source. The genome sequences of several Lemnaceae family members have become available, providing a foundation for genetic improvement of these plants as crops. The protocols for maximizing flowering described herein are based on screens testing daylength, a variety of media, supplementation with salicylic acid or ethylenediamine-N,N′-bis(2-hydroxyphenylacetic acid) (EDDHA), as well as various culture vessels for effects on flowering of verified Lemnaceae strains available from the Rutgers Duckweed Stock Cooperative.

This is a disorganized book, but I think it is purposely so. Dr. Brodey states at one point that the family therapist's main role is that of example, and the style of this volume is an example of the freedom of expression which the author feels is essential to healthy family living. Dr. Brodey believes that traditions and stereotypes destroy families and cause illness in family members. He emphasizes the importance of the here and now over the past and stresses the value of evolvement and constant change to adapt to changing circumstances and to individual growth.

Using the capability approach initially developed by A Sen as a theoretical framework, this paper analyses both what people with dementia and their families do in response to difficulties in their daily life brought about by the disease, and the reasons they give for acting as they do. Individual and collective interviews and ethnographic observations with 15 persons with dementia and one or more of their family members were conducted. Follow-up interviews were possible for nine families. Results highlight a great diversity in ways of doing things and in accompaniment by family members. Daily adjustments are often hidden or minimized, at least at the onset of the dementia. Later, they become more frequent, repetitive and indispensable but remain influenced by the social and gender roles that existed prior to the illness. The inventiveness of families, in a context marked by various kinds of constraints, is primarily motivated by their desire to maintain the apparently intact abilities of the person with dementia but especially to preserve forms of liberty and what counted for the person, what that person valued before the disease. There are some ways of living with dementia, even when accompanied, which may long remain preferable to others, which better answer to the past and present aspirations of persons with dementia and the purposes of the accompanying persons. It is thus essential that health professionals, as well as society in general, recognize and address this issue.

ABSTRACTThis paper presents a novel conceptualization of emotional support in intergenerational families. In a stratified random sample of 458 adults in Hamilton, Ontario, over half the respondents said that there was currently, or had been in the past, a person in their family to whom other family members turned for emotional support and personal advice. In the paper, this person is referred to as the “comforter.” Many people also identified the person who provided emotional support prior to the present comforter. On the basis of the data, a “position” of family comforter is inferred. The paper investigates the social correlates of the position, the type of activities associated with being the family comforter, and the pattern of succession as different generations in the family move in and out of the position. The paper demonstrates the family provision of emotional support at the level of the extended family. It is shown that occupancy, activities and succession of the comforter position are patterned by gender. Further, the data suggest that people seek emotional support from a generational peer.

In the past 10-15 years, the consumption of illegal drugs has increased significantly both in Hungary and in our county. In parallel with the society's getting more and more open, the fulfilment of personal freedom, and the spreading of globalisation and individual culture, the use of drugs has become more and more accessible and acceptable to the young. This study briefly overviews the family background and problems of provincial young people consuming drugs. I have studied 3 problems within this topic: family structure, relations with parents, and family members' drug consumption behaviour. I suppose that family problems are connected with the interviewees' alcohol and other drug consumption. In my research I apply the Euroadad questionnaire. The sample covers 144 interviewees, 76.9% of whom have been "diverted" from jurisdiction. The other respondents have volunteered for the therapy.I have processed the data with the SPSS statistical program package. Having studied the respondents' family structure, I have found no significant difference regarding the co-habitation data for the past 30 days or the past year. The family members' alcohol and drug consumption bears a greater relation to the use of legal drugs than of prohibited ones. The family problems related to parents are connected to the young people's prohibited and legal drug consumption, and fathers play a particularly stressed role. The groups of party drug and amphetamine consumers struggle with more family problems than the groups of marijuana users.

The development of relationships between young people and the generation of the grandparents must be accompanied by a sense of solidarity and the need to share experiences, especially in the family circle. In this way, young people are slowly gaining experience in finding thread of understanding and creating relations with other people from the atomising population. Mutual understanding and keeping good relations between the generations also prevents the isolation and marginalization of the older generation; then the young people do not see any interest to „help” them in this. Today we can observe with concern how the culture of the nations living with the present moment is getting exhausted and disappears because the individual gradually is losing its connection with family members and the roots of its own history. After all, the older people are able to offer invaluable assistance to young people, they can be and should be the trustees of the past and all these things in order to prevent a young generation from forgetting traditions, customs, art, religion, music, culture, and crafts of their fathers.

The results of the study found that the responsibility of religious education of children in the family of Tablighi Jama'ah differed in terms of several conditions, namely first, when parents were not going to khuruj where both parents were responsible for children's education; secondly, when the father goes khuruj, then the mother is responsible for everything including children's education; third, when both parents go khuruj, then the responsibility of the child is left to other family members such as grandparents or their first adult children; and fourth, when the child goes to khuruj, where parents are responsible for children's religious education both mother and father. The pattern of the religious education in the Tablighi Jama'ah family in the village of Bolang is formed from several similarities held in the implementation of religious education, one of which is the daily activity that is carried out by the Tablighi Jama'at family. Al-Qur'an becomes one of the material given to children in the ta'lim. Children are taught how to read the Qur'an and memorize short letters such as Surat al-Falaq, al-Ikhlas, and so on. In addition to al-Qur'an, in this ta'lim there is a special study in the Tablighi Jama'ah, which is reading the book of fadhilah ‘amal, and the last is mudzakarah six characteristics.

Canada has an aging population with the fastest growing age groups (80 and 45-64 years old) vulnerable to age-related diseases such as Alzheimer’s disease. Caregiving responsibilities often fall to the family members of the afflicted without much attention and consideration being placed on the information needs of these caregivers. We call for a better understanding of these caregivers' information needs and uses by social policy makers as well as information providers.La population du Canada a tendance à vieillir considérablement, avec la hausse la plus rapide dans les groupes d’âge (80 et 45 à 64 ans). Les personnes âges sont très vulnérables à toute sorte de maladies, telles que la maladie d’Alzheimer. La responsabilité revient souvent aux membres de la famille qui doivent prendre soin des personnes atteintes de cette maladie. Or, nous ne connaissons que peu de chose sur les besoins en information des personnes qui prennent soin de ces malades de l’Alzheimer : qui sont-ils ? Quelles sont leurs sources...
