<p>Do youths know what life values their parents have? Does this knowledge have a connection with the youth’s attachment to their parents? Do the youth’s life values differ from their parents? And could the youth’s life values affect how they estimate their parent’s life values? To answer these questions data from a survey were used. The respondents were 13-15 years old youths and their parents. The results show that youths do not know what life values their parents have, irrespective of if the attachment to them is good or bad. The results also show that the youth’s own life values to a high extend affect how they estimate their parent’s life values. They think that they and their parents have almost the same life values, but the results show that it’s not so. Thus youth’s good attachment to their parents does not have to mean that they know what life values their parents have.</p> / <p>Vet ungdomar vad deras föräldrar har för livsvärden?

The bottom-up assembly of functional devices requires novel building blocks to facilitate the incorporation of functional and structural hierarchy. Anisotropic building blocks can substantially broaden the creation of self-assembled devices with unique properties because of their morphological and/or chemical asymmetry. In this regard, we have created microspheres with one hemispherical face exposing silica and the other exposing gold. These microspheres were formed by the shadow deposition of gold onto silica microspheres. The two chemical surfaces allowed use of different surface reactions—silane chemistry for the silica side and thiol chemistry for the gold side—for immobilizing different oligonucleotide sequences on each of the two faces. These dual-functionalized microspheres were used in the selective orthogonal assembly of fluorophore-tagged target oligonucleotides. The DNA-directed assembly was confirmed by confocal microscopy of the microspheres. In essence, employing DNA as the linker molecule, these “Janus” particles can be assembled into various novel 1-D, 2-D, and 3-D structures, which are difficult to realize using symmetric building blocks. / Singapore-MIT Alliance (SMA)

Multiple Sclerosis (MS) is the most common demyelinating disease affecting the central nervous system. Over 80% of MS patients are in the relapsing remitting stage. Symptoms range from fever, fatigue, emotional distress, tingling, numbness, optic neuritis, spasticity, muscle weakness, impaired coordination, to other abnormal neurological problems. Expression of symptoms is known as a relapse or exacerbation. The cause of relapses is unknown, but multiple factors seem to play a significant role. Possible factors that may influence MS onset and relapse consist of a genetic association, viruses, disruption of the blood-brain barrier, and stress. Stress has shown to have negative implications and may stimulate relapses. Thus, this study examined a possible stress intervention that most people already had available to them, companion animals. Companion animals have been shown to lower blood pressure, decrease heart rate, provide social support, and reduce stress. The main hypothesis was to evaluate whether or not pet ownership and/or attachment influenced the perceived stress level and number of negative life events experienced by MS patients in the relapsing remitting stage. Participants were given a questionnaire that consisted of 7 surveys. The questionnaire accessed quality of life, disease severity, number of negative life events, perceived stress level, level of depression, social support, and pet ownership and attachment level. Our sample population consisted of MS patients seen at the University of Texas Southwestern Neurology clinic from February 23rd to May 21st, 2004. One hundred and forty seven relapsing remitting MS patients were included in the study. Multiple linear regression was used to compare the relationship of stress and number of negative life events to pet ownership and attachment. Results revealed that pet ownership and attachment levels did not affect the stress level and number of negative life events of MS patients. No confounders were identified. Interaction terms with disease severity as the dependent variable, pet ownership and perceived stress level or negative life events as the independent variables were not significant. The type of pet owned did not influence the attachment level of the MS patient. In conclusion, the results of this study did not support the hypothesis.

Salmonella outbreaks associated with orange juices have been reported in the past. Though there have been studies on the internalization of Salmonella into oranges there is inadequate information on the ability of this pathogen to survive on orange surfaces, become internalized, and survive the low pH internal conditions. The objective of this work was to study the survival of Salmonella gaminara and Salmonella agona on oranges obtained from the field and retail outlets and investigate their attachment and internalization potential. These studies showed that oranges obtained from both the field and retail outlets harbored relatively high concentrations of aerobic heterotrophic bacterial populations. There were significant differences in the survival of Salmonella agona and Salmonella gaminara at 4??C, room temperature (25??C) and 37??C. Survival was highest at 37??C and lowest at 4??C for both Salmonella gaminara and Salmonella agona. Salmonella agona and Salmonella gaminara showed significant differences in recovery when the cells were treated with pH 4.0, 7.0 and 9.5 buffers. The internalization studies suggest that a negative temperature differential favors the internalization of Salmonella cells into the fruit. Significant differences in the internalization of Salmonella into field and market oranges were observed with more internalization in the field oranges as compared to the market oranges. These results suggest that to prevent Salmonella contamination of orange juices adequate pre-harvest protection against pathogen contamination and post-harvest cleaning and disinfection strategies need to be employed.

A telephone questionnaire was developed to collect information on pet owners, cat ownership patterns, and people's opinions about homeless pets. A 7-day observation log was also developed to gather information about free-roaming cats in Caldwell, TX. The objectives of this research were: (1) to evaluate the reliability of the telephone questionnaire, (2) to assess general cat ownership patterns, (3) to evaluate attachment level of pet owners to their pets, (4) to determine general opinions about free-roaming cats, (5) to determine if demographics were associated with opinions about free-roaming cat and dog problems and (6) to investigate free-roaming cat activity in a community. Telephone questionnaire information collected from 100 subjects was tested for reliability. Reliability was fair to good for cat level questions (sex, age, breed, length of time owned, indoor/outdoor status, litter, number of vet visits, vaccinated). Reliability was good for questions concerning subjects' knowledge of cat and dog behavior and levels of attachment to their pets. Reliability was excellent for all household level (demographic) variables. Reliability was moderate for questions regarding subjects' opinions about homeless animals. Telephone questionnaire responses collected from 441 subjects were checked for associations using exploratory logistic and linear regression models. A cat's role as a pet, vaccination status, and the length of time owned were associated with a cat's sterilization status. A cat's role as a pet was associated with the cat's indoor/outdoor status. Household size, education level and ethnicity of the owner were associated with cat ownership. Having children was associated with a negative opinion about homeless cats. Education level was associated with subjects' knowledge about dog and cat behavior. Gender, household size, and knowledge score were associated with subjects' attachment to their pets. Descriptive information on free-roaming cat activity was collected from 21 subjects using the 7-day observation log. Subjects made 382 cat sightings during the study period. Slightly more cat sightings were made during the morning than in the evening and afternoon. Most cats were spotted in neighborhoods and were resting or eating. Most of these cats that were eating were seen during the morning or evening hours.

For parents, the birth of their first child sparks rapid change for each partner and for their romantic relationship. With the stress of the transition to parenthood, many couples experience declining marital satisfaction. However, previous studies have reported wide variation in the magnitude and time course of this decline. The present study sought to determine the trajectory of marital satisfaction across the first 2 years of parenthood. The study also examined the role of anxious and avoidant attachment, as well as relationship dynamics that prevent or augment declines in satisfaction for anxious and avoidant individuals. Data were collected from couples in five assessment waves: 6 weeks before the birth of the first child, and 6, 12, 18, and 24 months postbirth. Both partners completed self-report measures of attachment orientations and relevant situational stressors. It was hypothesized that, for insecurely attached partners, declines in marital satisfaction would be associated with the inability to pursue attachment-related goals. Thus, satisfaction should decline when: 1) anxious individuals are unable to increase proximity to their partners; and 2) avoidant individuals are unable to increase distance from their partners. Growth curve models examined changes in satisfaction over time, moderated by gender, attachment orientation (anxiety or avoidance), and situational stressors. Results yielded three key findings, which largely supported the hypotheses. First, for highly anxious individuals, satisfaction was lower or declined when they perceived their partners as less supportive and more negative toward them, and when they felt their babies interfered more in their romantic relationship. Second, for highly avoidant individuals, satisfaction was lower or declined when they felt their babies interfered more in leisure activities, and when they perceived more work-family conflict and more demands from their families. Third, an interesting pattern of gender differences emerged, such that satisfaction often declined more steeply in insecure men than women. Exploratory analyses revealed additional moderators of the attachment-satisfaction relationship. These are discussed as they relate to the goals of insecurely attached individuals. Findings suggest that attachment insecurities predict dissatisfaction in new parents primarily when situational stressors block the pursuit of secondary attachment goals.

This study investigated the extent to which memories of parental rearing were related to the quality of parent and peer attachment, and whether parent and peer attachment were correlated with social anxiety feelings among 510 Chinese high school students. Memories of parental rearing were measured by the My Memories of Upbringing for Children (EMBU-C), The Inventory of Parent and Peer Attachment (IPPA) was used to assess attachment quality and social anxiety was assessed by Social Anxiety Scale for Adolescents (SAS-A) with adolescents in two age-groups. Consistent with findings from Western samples, the analyses revealed significant associations between attachment and memories of parental warm emotions as well as with memories of parental rejection. Attachment scores were related to level of social anxiety. Moreover, peer attachment was stronger associated with the adolescent¡¯s social anxiety feelings than parent attachment. However, the age differences were found across each measure scale. Furthermore, fathers showed a moderately more important role in the adolescent¡¯s social development than mothers. The findings indicate that in spite of considerable consistency with findings from Western studies, child-parent attachment in Chinese adolescents is also influenced by culture-specific practices that shape the youth-parent relationships and their meaning to the child.
