The genus Alnus ( Betulaceae ) includes thirty-five species distributed across northern hemisphere (http://www.discoverlife.org). There are four species native to Europe: A. incana (grey alder), A. cordata (Italian or Corsica alder ), A. glutinosa (common or black alder) and A. viridis (green alder). In addition, A. rubra native to North America has been extensively planted in some European countries (Claessens, 2003). Alnus sp. plays important ecological roles. It is a pioneer genus, tolerant of high ground water levels and periodic flooding. A. glutinosa is the most common species and is present throughout Europe up to 1800 m. It is well adapted to wet sites and plays a vital role in riparian ecosystems as the root system helps to stabilise riverbanks reducing the effect of erosion (Webber et al., 2004). Black alder has a beneficial effect on soil (porosity, symbiosis with Frankia ), on water quality (filtration, purification) and also on fauna. It contributes to increase the biodiversity of birds and insects and its root system allows fish to shelter. Alnus incana is widely distributed in central and eastern Europe. In the south, it grows mainly in mountain areas. As it is a root sprout pioneer that tolerates both dry conditions and flooding, A. incana is very important for improving the stability of slopes and riverbanks (Jung & Blaschke, 2004). A. cordata and A. viridis are much less frequent species and are native to Corsica-Italy and mountains of central Europe, respectively (Claessens, 2003).

The total picture given of these Highgate families is a complex one. The individuals come from diverse origins, in geographical, social and occupational terms. Not only have many of them moved to London from other areas, but also most of their siblings and other kin have been equally mobile. In very few cases have kinship ties or obligations entered into decisions to move, either in the case of the informants themselves or their siblings and parents. Mobility in all generations, undictated by kinship ties, has led to a wide scatter of families all over the country and overseas. This mobility is largely a function of the sort of careers taken up by both the men and the women. Apart from this, however, it can be seen that it is also made easier by the relative independence of children from their parents at an early stage. There are explicit attitudes, held by both children and parents, that they should be independent of one another at least in the daily functioning of their lives. Children often go to boarding schools, later to colleges and universities, and are prepared, for the latter, to live at great distances from their families. This does not mean that relationships are ineffective or necessarily distant between parents and children, or between other sorts of kin. The expected patterns of behaviour are based on strong affective ties which are not, however, expressed in frequent and intense interchange of contact and services or mutual dependence. Just because there is not frequent and intense contact does not mean that the affective tie does not exist. Nor that, in certain circumstances, kin are not called upon for assistance or advice. It is significant that certain services are given regardless of the geographical distance between kin. For example, one of the situations in which mothers are most frequently called in to help is at the birth of a baby. Nearly all the young wives had their mothers to stay in the house at least during one confinement, i.e. when she herself was in hospital. Many mothers travelled from great distances to do this, one or two even from abroad. Thus it can be seen that distance is no barrier to the sort of services these sort of people tend to need. Neither mothers nor daughters expect or want daily exchange of household services in normal circumstances, neither do they generally want constant contact with each other. The type of relationship between parents and children obviously determines to a large extent the sort of relationships an individual will have with the rest of his or her kin. If a relationship with a parent is not manifested in constant interaction then two things result. Firstly, the ideology and attitudes with which a child is brought up will be of such a kind that he does not expect a close relationship with his extra-familial kin, and secondly, because of relatively infrequent contact with parents and siblings, genealogically more distant kin will enter into his life even less, and ties even with relatives who may be in constant contact with a parent may be dropped or maintained according to individual preferences. In this sense geographical distance may enable ties to be dropped without, generally, upsetting the relationships between other kin. Considering a wide divergence of occupations and cultural interests and, in some cases, of class background, a great many ties are maintained with relatives. Generally, contact is not frequent, but this seems to bear little direct relation to geographical distance except insofar as the latter acts as an extreme limiting factor. Where people want to see their kin, wide distances are covered relatively often. Expectations of extra-familial kin behaviour do not usually demand frequent contact, even when proximity allows it. With closer kin, specifically parents and siblings, there is more evidence to support the hypothesis (often held for all kin) that as much interaction will take place as possible at all times. Even for parents and siblings this is not entirely so, but here behaviour approximates more to this hypothesis, and this is so in spite of the ideology of independence with which children grow up, and the complex set of circumstances arising out of a wide range of occupations and cultural interests. Ties with kin outside the family of origin are maintained on a more selective basis, and they are often manifested only in contact of an intermittent nature. Partly this is because these ties are not often of a very strong kind - it is fair to say that to a great extent these people function independently of the majority of their kin. But it is also partly because more overt behaviour patterns of any more intense nature are not expected between members of these families.

Stakeholder engagement in air route development - The role of leadership and governance

These years, media firms begin to invest in culture industry. This Phenomenon can be witnessed in art exhibitions held by the China Times and the United Daily News. The article case-studies the intention of media firms to hold art exhibitions and analyzes how they employ their own resources to create synergy. We found that by organizing such fairs, media firms can use their own sources to reduce financial risk and achieve operational synergy. The strategy for promoting art exhibitions is different from marketing regular commodities. Besides, by promoting art, media firms become more competitive and can develop a symbiotic relation with the field of artistic production.

In natural condition, Arbuscular Mycorrhizal Fungi (AMF) are surrounded by bacteria that help fungi symbiosis. The research aimed to get rhizobacteria that can act as Mycorrhiza Helper Bacteria (MHB) had been held at Soil Biology and Biotechnology Laboratory Faculty of Agriculture Unpad from February to March 2012. The experimental design used was completely randomized design with 11 treatments (bo= without rhizobacteria, b1= Pseudomonas diminuta, b2 = Bacillus alvei, b3 = B. mycoides, b4 = P. malei, b5= P. diminuta + B. alvei, b6 = P. diminuta + B. mycoides, b7 = P. diminuta + P. malei, b8 = B. alvei + B. mycoides, b9 = B. alvei + P. malei, b10= B. mycoides + P. malei) with 3 replications. Parameters evaluated were spore germination percentage and hyphal length of Glomus sp at 7, 14, 21, and 28 day after planting. The result showed that P. diminuta enhanced spore germination percentage and hyphal length of Glomus spas much as 224 % and 330%respectively than control. So, P. diminuta can be used as MHB.
