ABSTRACT: The insects of the family Bruchidae (Coleoptera) are important predators; their larvae feed upon and live in the seeds of a wide variety of plants. In Argentina, there not exists background information concerning the levels of predation of Ipomoea nil (Convolvulaceae) seeds caused by these insects. Thus, the aim of this work was to record the incidence of the species of the genus Megacerus as predators of I. nil seeds, an important weed affecting cotton growing in the irrigation area of Santiago del Estero. Megacerus maculiventris was the only bruchine species identified as predator of this weed. The predation percentage ranged from 0.84 to 15.66% in the agricultural years 2004-2008. It was attested that the number of predated seeds per capsule is independent from the number of seeds per fruit. However, it was proved that the insect predates just one seed per capsule and the highest predation frequency occurs in fruits containing more than three seeds. The levels of predation of I. nil by M. maculiventris are low in relation to those registered in other hosts by bruchines of the genus Megacerus.

Most picornaviruses of the family Picornaviridae are relatively well known, but there are certain “neglected” genera like Bopivirus, containing a single uncharacterised sequence (bopivirus A1, KM589358) with very limited background information. In this study, three novel picornaviruses provisionally called ovipi-, gopi- and bopivirus/Hun (MW298057-MW298059) from enteric samples of asymptomatic ovine, caprine and bovine respectively, were determined using RT-PCR and dye-terminator sequencing techniques. These monophyletic viruses share the same type II-like IRES, NPGP-type 2A, similar genome layout (4-3-4) and cre-localisations. Culture attempts of the study viruses, using six different cell lines, yielded no evidence of viral growth in vitro. Genomic and phylogenetic analyses show that bopivirus/Hun of bovine belongs to the species Bopivirus A, while the closely related ovine-origin ovipi- and caprine-origin gopivirus could belong to a novel species “Bopivirus B” in the genus Bopivirus. Epidemiological investigation of N = 269 faecal samples of livestock (ovine, caprine, bovine, swine and rabbit) from different farms in Hungary showed that bopiviruses were most prevalent among <12-month-old ovine, caprine and bovine, but undetectable in swine and rabbit. VP1 capsid-based phylogenetic analyses revealed the presence of multiple lineages/genotypes, including closely related ovine/caprine strains, suggesting the possibility of ovine–caprine interspecies transmission of certain bopiviruses.

A homicide study undertaken at the Ontario Hospital, Penetanguishene, yielded 100 cases in which mental illness was present, or considered to be present, at the time of the act. This paper deals with some selected structural data on the total group, leaving dynamic material for intensive investigation of various subgroups. The 100 patients had killed 110 victims and wounded a further 26. About half of the cases involved homicide within the family. Background information on the patients and some personal and social factors are considered. In terms of diagnosis, more than half were schizophrenics. The peak in the ages of patients at the time of the offence is in the 30 to 35 year age group, but this differs in the various forms of homicides. Seasonal variations indicate peaks in early spring and fall, with another increase in December in the Christmas period. No specific weekday pattern emerged and the daily pattern suggests an increase in frequency from early morning to late evening. Most of the homicides took place in or close to the residence of offender or victim. Shooting was the most common method of attack. After the act, the majority of offenders made no attempt to escape. The analysis will be continued in greater detail and with comparative material from the literature. These future papers will be concerned with specific groups, such as matricide, patricide, and wife murder.

Different seeds are dispersed from infested to uninfested areas possibly due to several biotic and abiotic mechanisms, and this spread of seed aids the invasion process across the landscape. Currently, in District Charsadda KP, Pakistan, there are about thousands of motorized vehicles, each capable of carrying infested seeds and therefore spreading crop seeds and plant seeds. Studies were conducted in 2019 to investigate the role of the utility vehicles in the dispersal of seeds in District Charsadda. A large number of seeds were found on vehicles. In the current study undertaken in KP, the maximum number of species from the family Apiaceae (3.00), Poaceae (3.00) and Solanaceae (3.00) were found dominant on the vehicles. Whereas, the minimum species number from the family Asteraceae (1.00), Fabaceae (1.00), Ebenaceae (1.00), Umbelliferae (1.00) and Cucurbitaceae (1.00) were associated with the vehicle. These seeds were found on several parts of the vehicles and were contained within mud or dust that had presumably transferred to the vehicle as it undertook its routine activities. The early implications from this present study is that utility vehicles are capable of collecting, carrying, and presumably distributing large numbers of seeds that seed is carried on many parts of the vehicle. Thus, any washing or cleaning procedure used to remove seeds from vehicles will need to concentrate on all parts of the vehicle. Cleaning vehicles at appropriate places should be seen as a possible way to reduce seed spread by utility vehicles.


HOW WE GET INVOLVED WITH COURT-MANDATED PARENTS Because of the emotional intensity and conflict that is typical of many court-mandated clients, our approach begins with the initial telephone contact. When parents are ordered to therapy to help settle custody and/or visitation issues, usually one parent calls in explaining that they have been court-ordered to therapy. When this happens, we take down some basic information and explain that we must wait for the other parent to call in before therapy can begin. If we see one parent before making contact with the other, we are likely to become part of the adversarial climate characteristic of the court. In a few cases, an attorney or guardian ad litem will refer the case directly to us. They usually want to give us background information about the family. We thank them for this input and ask that they have the family call us directly so we can tell them about our center and how we work. We also tell the referral source that therapy will begin after we hear from both parents.When the first parent calls in, they often tell us that we shouldn't expect a call from the other parent, saying, "I asked him/her to come to therapy a hundred times when we were married and he/she always refused." Sometimes we receive a court-order from a judge in the mail; the court order explains who is referred to therapy and why. It usually states that the parents are having difficulty resolving issues regarding their children. These issues include disputes about visitation, custody, and financial support. It is important to note that some families we see are in the midst of the divorce process while others have been divorced for many years. THERAPIST POSITIONING We see our role with court-ordered families as flowing from our ideas about people, therapy, and change. So, when we work on these cases, we become part of a system of people engaged in a dialogue about the well-being of a family. It is important to note that no one involved with the family denies that the best interests of children are primary. What those best interests are, however, is open to debate. Our role, as we see it, is to join with members of each system (family,

Abstract Background : Adolescence is a fluctuating period wherein they love to do things as they wish and something that gives them a thrill without reasoning and hence they need to be guided. Objective : Determine the knowledge and find the effectiveness of an awareness program on substance abuse and its consequences among the PU College students.Find the association between the pretest knowledge scores and the selected variables like age, gender, monthly income of parents, and education of parents, birth order and history of substance abuse in the family. Method : A Pre-test post-test design was used. Fifty three students from Udupi district was selected by convenient sampling. The tool used was knowledge questionnaire on substance abuse and its consequences. Demographic proforma was used to collect the background information. SPSS software version 16 was used for data analysis. Results : Pretest knowledge shows that 91% of the students had average knowledge and about 2% of the students had poor knowledge whereas only 7% had good knowledge. The post-test result shows that 28(52.8%) students had good knowledge on substance abuse and its consequences. The indices show a steady increase in knowledge from 7.5 % during the pre-test to 52.8% during the posttest with a mean difference of 4.23 between pre-test and post-test at 0.05 level of significance(p>0.001) Conclusion : Awareness programme helps students to gain knowledge and helps in enlightening their future.

Genealogical research often focuses to varying degrees on the family tree and the ancestors that inhabit it, often ignoring, or at least downplaying, broader issues. There is, however, much scope for broadening the research by adding leaves and flowers to the fruit (the people) on the tree. The broader context to a person’s ancestry is often intriguing and enlightening, providing background information that places the people in their environments, perhaps explaining their actions and lifestyles in the process. Two aspects of this context are dealt with here. The first aspect relates to the place in which each person lives, in other words, to their geographical environment, both natural and social or human made. Secondly, their personal heritage is considered: this includes the most important items in their lives, perhaps inconsequential to others but with long-term meaning for them and quite possibly for their descendants. Other broader aspects of heritage may well be relevant, too.

A controlled crossing experiment using a factorial mating design, involving female parents of E. pellita and male parents of E. urophyla that randomly sampled from the breeding population of both species, was conducted to assess the degree of genetic control on interspecific crossability for hybrid between E. pellita and E. urophylla. As measures of crossability, number of seeds per capsule and percentage of germinated seed were determined for each individual cross. The effect of female, male and female × male was significant on number of seed per capsule and percentage of germination. There was a slight tendency that the family produced more viable seed might produce less viable seed. Additive and dominance genetic varians were estimated as measures of the genetic control. The dominance variance had the major contribution to the genetic control of seed production and seed germination. Female source of variation has the major contribution to the additive genetic influence. Therefore, to maximize the production of viable seed, parent trees with desired traits should be selected on specific cross basis.

Martin Luther about dishonesty in the economy. This article is about Martin Luther’s economic ethics. Background information is given about the economic situation 500 years ago. The high levels of poverty in Germany were the main reason behind the health crisis experienced at that time. Luther reprimanded the heads of families to work diligently and honestly in order to ensure a stable income for the family. He prophetically also criticised the dishonesty on the market place. He exposed the many attempts by people to exploit the poor. An overview is given of the development of his economic thought. The focus falls, however, on his essay Von Kaufshandlung und Wucher (1524) [On trade and profiteering].

ABSTRACT Fertility of hybrid tea roses is often reduced due to their interspesific origin but also to intensive inbreeding. New genotypes used as pollen donors represent an economic risk for a breeding program, as their influence on seed production is unknown. In this study 9 garden rose genotypes were selected from a company database as high fertile or low fertile male parents, according to the number of seeds per hybridization. Pollen morphology and in vitro germination of the selected genotypes were characterized. Pollen was either small (mean diameter = 30 urn), shrunken, and irregular (abnormal), or large (mean diameter = 30 urn), elliptical and crossed by furrows (normal). High correlations were found between the number of seeds produced per hybridization and the pollen diameter (r = 0.94) or the percentage of normal pollen (r = 0.96). In order to evaluate the predictive power of the models, we conducted regression analyses and performed a validation experiment on genotypes not present in the database and without background information on fertility. Pollen diameter and percentage of normal pollen were characterized and fitted in the regression models for seed set predictions. Validation with an independent dataset gave a good prediction for 83.3% of the data. This indicates that using either the mean pollen diameter or the percentage of normal pollen resulted in effective fertility prediction. Moreover cluster analysis of the data classified all the cultivars into various groups with varying fertility. This tool could enhance the genetic variability in crossings between hybrid tea roses, thus creating possibilities for less economically risky exploitation of new tetraploid genotypes as male parents.
