Moroccan pepper virus (MPV) and Lettuce necrotic stunt virus (LNSV) have been steadily increasing in prevalence in central Asia and western North America, respectively, over the past decade. Recent sequence analysis of LNSV demonstrated a close relationship between the coat proteins of LNSV and MPV. To determine the full extent of the relationship between LNSV and MPV, the genomes of three MPV isolates were sequenced and compared with that of LNSV. Sequence analysis demonstrated that genomic nucleotide sequences as well as virus-encoded proteins of the three MPV isolates and LNSV shared 97% or greater identity. A full-length clone of a California LNSV isolate was developed and virus derived from infectious transcripts was used to evaluate host plant reactions under controlled conditions. Symptoms of LNSV matched those described previously for MPV on most of a select series of host plants, although some differences were observed. Collectively, these molecular and biological results demonstrate that LNSV should be classified as MPV within the family Tombusviridae, genus Tombusvirus, and confirm the presence of MPV in North America.

ABSTRACT Human immunodeficiency virus type 2 (HIV-2) originated from simian immunodeficiency viruses (SIVs) that naturally infect sooty mangabeys (SMs; Cercocebus atys). In order to further investigate the relationship between HIV-2 and SIVsm, the SIV specific to the SM, we characterized seven new SIVsm strains from SMs sold in Sierra Leone markets as bush meat. The gag, pol, and env sequences showed that, while the viruses of all seven SMs belonged to the SIVsm-HIV-2 lineage, they were highly divergent viruses, in spite of the fact that most of the samples originated from the same geographical region. They clustered in three lineages, two of which have been previously reported. Two of the new SIVsm strains clustered differently in gag and env phylogenetic trees, suggesting SIVsm recombination that had occurred in the past. In spite of the fact that our study doubles the number of known SIVsm strains from wild SMs, none of the simian strains were close to the groups in which HIV-2 was epidemic (groups A and B).

The genus Cryptantha Lehm ex G. Don section Oreocarya (E. Greene) Payson of the family Boraginaceae presents some problems to botanists, both professional and amateur, in the keying and identification of species. The genus contains approximately 150 species, the section about 60 perennial and biennial herbs located generally in western North America. Identification has presented some taxonomic difficulty due to the variability and lack of distinctive vegetative characters. Botanists have turned to the nutlet (fruit) and flower morphology to aid in identification for precise specific differentiation. In the past, 10X magnification and a decent botanical illustrator were required to provide the illustrations necessary to assist in this identification. We are in the process of collecting micrographs of nutlets (dorsal, sagital, and ventral views) and developing a webpage containing these micrographs along with descriptions of their morphological variations.


Considering the significance of Adolescents behaviour in family purchase decisions, the study initiated with the objective to unearth the adolescents influence on the buying decisions of the family. The purpose of the study is listed down into three parts: Firstly, to explore the relationship between the age of adolescents and its effect on buying decisions of family. The next objective is to catalogue and position the products on the basis of influence of Adolescents. Subsequently, the other task is to examine and establish the comparative analysis of Adolescents influence for three different goods categories (so designed) and also analysing it at various stages of Family purchase process. The research methodology is based on the study of relevant review work done in the past and an interview conducted amongst the adolescents for the data collection. Furthermore, a structured questionnaire is circulated amongst adolescents aged between 14-19 years. Data was collected from 350 adolescents. Study also exhibited that there are three product categories identified by factor analysis explicitly “Prominent” Products, “Popular” Products and “Common” Products– It was observed that Popular products gained maximum attention of adolescents, followed by Prominent Products and the least attention seeker for adolescents are Common Products. These categories are designed in context to Indian families & environment. Multivariate Analysis of Variance, i.e., MANOVA was also applied for third objective which presented the outcome that in case of Prominent and Popular Products, adolescent’s impact is greatest at the beginning stage of the purchase process and least at exploration stage. But in case of Common Products, Adolescents influence is highest at the stage of decision making and selection. This study can have enormous future relevance for the marketers by the way of providing them with broad scope of adolescents’ behavioural understanding in family in context to different product categories and at multiple buying stages of family purchase process. This could be considered as the base for formulating and executing various marketing plans. The paper bears uniqueness in terms of analysing adolescents’ behaviour in relation to multiple product catalogues and relating the segmentation across various family buying stages.

Over the past 20 years, the term “ecosystem” has become pervasive in discussions of strategy, both scholarly and applied. Its rise has mirrored an increasing interest and concern among both researchers and managers with interdependence across organizations and activities. This article presents a structuralist approach to conceptualizing the ecosystem construct. It presents a clear definition of the ecosystem construct, a grammar for characterizing ecosystem structure, and a characterization of the distinctive aspects of ecosystem strategy. This approach offers an explicit examination of the relationship among ecosystems and a host of alternative constructs (business models, platforms, coopetition, multisided markets, networks, technology systems, supply chains, value networks) that helps characterize where the ecosystem construct adds, and does not add, insight for the strategy literature.

The March 2016 eruption of Pavlof Volcano, Alaska, produced an ash plume that caused the cancellation of more than 100 flights in North America. The eruption generated strong tremor that was recorded by seismic and remote low-frequency acoustic (infrasound) stations, including the EarthScope Transportable Array. The relationship between the tremor amplitudes and plume height changes considerably between the waxing and waning portions of the eruption. Similar hysteresis has been observed between seismic river noise and discharge during storms, suggesting that flow and erosional processes in both rivers and volcanoes can produce irreversible structural changes that are detectable in geophysical data. We propose that the time-varying relationship at Pavlof arose from changes in the tremor source related to volcanic vent erosion. This relationship may improve estimates of volcanic emissions and characterization of eruption size and intensity.

In this article, the authors refer to the play “Kein Schiff wird kommen” (“No ship will come”), 2010, by a young German playwright Nisa-Momme Stockmann, in which “historical events are refracted in the context of personal events of the characters”. In the center of the play is a young man, a writer, who was commissioned by the theater to write about the fall of the Berlin Wall. The protagonist of the play is a representative of an indifferent generation, far from politics and history. In 1989, he himself was a child, and the reunification of Germany, at first glance, had no effect on him. However, upon closer inspection, it turns out that the fall of the wall turned out to be an important event for him and his family. Only an appeal to the history of the country and the family helps the character to resolve the internal conflict. This shows the relationship with the tradition of German literature after World War II: German writers often refer to historical facts in their works. The key topic is of guilt and responsibility, which has been rethought in the literature over the past 60 years. Analysing the drama allows us to conclude that modern young people reject their past, which causes the character's personality crisis, and it also leads to failure in communication. In addition, alongside with ousting the past, the problem of German identity arises.

This research aims to explore the kinship system of the Dayak Ribun tribe in West Kalimantan. It uses the kinship system tree to visualize the relationship roots. This effort is also based on the refinement of the tree that has existed in the past. Moreover, the method used is an ethnographic approach, where data collection is carried out explicitly using observation, in-depth interviews, and live-in. Ethnic ethnography is gathering a variety of information from its source. According to the results, the kinship system in the Dayak Ribun community is bilateral, that is, relations through two family lineages, both sides of the mother or wife and father or husband. The principle of heredity is bilateral, where the responsibilities of husband and wife are the same in the family, both in children's education and in controlling the family economy. The marriage of a family member who is still a descendant from both the father and the mother is strictly prohibited, which is only allowed to marry between cousins ​​three times. In the distribution of inheritance, there is no difference between sons and daughters. Still, there are differences in some instances, especially for those who remain with their parents. They will get a higher share because they are responsible for their parents' old age until they die.

The Family Law Act 1975 (Cth) provides that judges must not alter property rights on the breakdown of the relationship unless satisfied that it is just and equitable to do so. This is the principle of judicial restraint. In the past, and prior to the 2012 decision of the High Court in Stanford v Stanford, this principle was given almost no effect. The High Court sought to correct this approach, insisting that the family courts should not begin from an assumption that a couple’s property rights are or should be different from the state of the legal and equitable title. It also reaffirmed that there is no community of property in Australia. This article considers the significance of the principle of judicial restraint: first, in cases where the property is already jointly owned and, secondly, in cases where the couple have chosen to keep their finances separate.
