Theological Understanding

This article provided an overview of youth culture and how the media shapes youth culture today. Its specific aim was to focus on the access to sexual content that the different forms of media provide and the possible effect that they have on youth culture today. The sexual development of teenagers is one of the most important areas of their journey into adulthood and can easily be influenced by media messages on sex and sexuality. As such, the sexual behaviour of teenagers mostly seems to demonstrate a misconception on sex and sexuality. The author argued that sex and sexuality can also be viewed as theological issues and concluded by offering a few suggestions on how faith communities can become a more relevant and effective partner in fostering a theological understanding of sex and sexuality, especially to the youth.

Multiple Meanings

Summary: The body of evidence suggests that there is a causal association between nonfictional media reporting of suicide (in newspapers, on television, and in books) and actual suicide, and that there may be one between fictional media portrayal (in film and television, in music, and in plays) and actual suicide. This finding has been explained by social learning theory. The majority of studies upon which this finding is based fall into the media “effects tradition,” which has been criticized for its positivist-like approach that fails to take into account of media content or the capacity of audiences to make meaning out of messages. A cultural studies approach that relies on discourse and frame analyses to explore meanings, and that qualitatively examines the multiple meanings that audiences give to media messages, could complement the effects tradition. Together, these approaches have the potential to clarify the notion of what constitutes responsible reporting of suicide, and to broaden the framework for evaluating media performance.

Utilizing a 2 (lyrics: present or absent) × 2 (images: present or absent) design, this study examined the unique effects of sexually degrading music videos and music lyrics on males’ aggressive behavior toward women, as well as males’ endorsement of rape myths and sexual stereotypes. Under the guise of a media memory study, 187 male undergraduate students were randomly assigned to one of four conditions. Despite the many psychological theories predicting an effect, the presentation of sexually degrading content in a visual or auditory medium (or combination thereof) did not significantly alter the participants’ aggression and self-reported endorsement of rape myths and sexual stereotypes. The null findings challenge the many corporate and governmental restrictions placed on sexual content in the media over concern for harmful effects.

AbstractThe present study investigated the influence of related and unrelated emotions on judgments about a news article. An experimental study was designed to manipulate both the relatedness of an elicited emotion (i. e., anger) to the news article and processing depth. Following mood and emotion effects theory, related anger was expected to have a stronger effect on judgments about the media message than unrelated anger. Processing depth was expected to moderate this effect. The results showed a main effect of relatedness and a main effect of processing depth, but the interaction effect was not found. Implications of the findings for understanding how emotions influence the processing of media stimuli are discussed.

The purpose of this study was to investigate the roles of coral sands in the enrichment and isolation of ammonium-oxidizing bacteria (AOB). We hypothesized that the porous coral sands provided additional surface area and nutrients for the growth of periphytic AOB. In the present study, an orthogonal test was designed to compare the AOB conversion rates of ammonium-nitrogen (NH4+N) to nitrite-nitrogen (NO2--N) among various combinations of culture media. Results showed that the conversion of NH4+N to NO2--N increased significantly when the coral sands were added, implying that coral sands were beneficial to the growth of AOB. Additions of potassium dihydrogen phosphate (KH2PO4) or sodium bicarbonate (NaHCO3) to the media became unnecessary when coral sands were used, but the addition of KH2PO4was needed when the molar nitrogen to phosphorus (N:P) ratio reached 10 in the enrichment media using calcium carbonate (CaCO3) powder as a calcium source.

Abstract The present study aimed to identify biomarkers to assess the quality of in vitro produced (IVP) bovine embryos in the culture media. IVP embryos on Day (D) 5 of development were transferred to individual drops, where they were maintained for the last 48 h of culture. Thereafter, the medium was collected and the embryos were transferred to the recipients. After pregnancy diagnosis, the media were grouped into the pregnant and nonpregnant groups. The metabolic profiles of the media were analyzed via electrospray ionization mass spectrometry, and the concentrations of pyruvate, lactate, and glutamate were assessed using fluorimetry. The spectrometric profile revealed that the media from embryos from the pregnant group presented a higher signal intensity compared to that of the nonpregnant group; the ions 156.13 Da [M + H]+, 444.33 Da [M + H]+, and 305.97 Da [M + H]+ were identified as biomarkers. Spent culture medium from expanded blastocysts (Bx) that established pregnancy had a greater concentration of pyruvate (p = 0.0174) and lesser concentration of lactate (p = 0.042) than spent culture medium from Bx that did not establish pregnancy. Moreover, pyruvate in the culture media of Bx can predict pregnancy with 90.9% sensitivity and 75% specificity. In conclusion, we identified markers in the culture media that helped in assessing the most viable IVP embryos with a greater potential to establish pregnancy.

The current research was carried out to investigate the effects of iron source in the culture media for Vaccinium corymbosum L. ʻBluerayʼ, ʻDukeʼ, and ʻPatriotʼ cultivars grown on five different types of medium (Woody Plant Medium supplemented with 1.0 mg·L−1 zeatin and 0, 25, 50, 75, and 100 mg·L−1 Sequestrene 138). After 10 weeks of culture, seven physiological parameters were measured, such as the number and length of axillary shoots, rooting and acclimatization percentage, as well as chlorophyll (a, b, a/b) and carotenoid content of the leaves. Adding Sequestrene 138 to the culture media led to a slight decrease of the proliferation rate but increased the length of the shoots. The chlorophyll and carotenoid content in all of the three cultivars was considerably increased as the iron concentration of the media increased. The shoots developed on the Sequestrene 138–free medium were chlorotic and short, whereas at different concentrations of iron in the culture medium the shoots were dark green and vigorous, providing a greater acclimatization success than those grown in iron-free medium.

The diffusible brown pigment produced by some strains of Xanthomonas campestris pv. phaseoli was found to be due to the secretion and subsequent oxidation of homogentisic acid (2, 5-dihydroxyphenylacetic acid) rather than tyrosinase activity as previously reported. Homogentisic acid is an intermediate in tyrosine catabolism for a number of bacteria. Brown-pigmented strains appeared to be disrupted in tyrosine catabolism and could not use tyrosine as a nutrient. Nonpigmented strains, however, could utilize tyrosine as a nutrient, and although they secreted homogentisic acid, the levels were approximately 1/100th that of brown-pigmented strains. Production of brown pigment was stimulated by tyrosine and repressed by glucose. Growth in glucose resulted in a drop in the pH of the media, and the greatest pigment formation was associated with a shift to alkaline conditions in the culture media. By buffering the media near pH 7.0, brown pigment formation was repressed, even though unoxidized homogentisic acid accumulated in the culture media. The disruption of tyrosine catabolism corresponds to other reports describing differences between brown-pigmented and nonpigmented strains, and provides further support for the retention of a special taxonomic status for the brown-pigmented strains.Key words: homogentisic acid, pigments, Xanthomonas, fuscans.

The chrome shavings waste obtained as a result of the leather finishing process accumulates in a large volume in tanneries and represent a major problem for the environment. This waste are particularly resistant to attack of microorganisms, due to the significant concentration of chromium and are thus difficult to degrade. In this study, chrome shavings were analyzed microbiologically by determining the total number of germs and the number of yeasts and molds on specific culture media. Several bacterial and fungal strains were isolated from the cultures in Petri dishes, after the growth of the colonies. These strains were characterized in terms of the production of proteolytic enzymes, by a method of screening on the media with casein, which allows the determination of proteolytic indices of microorganisms. As a result of the tests performed, five bacterial strains probably belonging to the genus Bacillus and two fungal strains from the genera Penicillium and Cladosporium were selected.

Maggot black soldier fly (Hermetia illucens) is an insect that is environmentally friendly and can be mass produced and does not compete with humans. In addition, insect cultivation can reduce organic waste that has the potential to pollute the environment. Maggot black soldier fly (Hermetia illucens) has a high crude protein content of 42.1%. The length of the life cycle and the high and low nutrient content of the maggot are influenced by the maggot growing media used. In this study using EM4 as a bio-activator for fermentation of rice bran, coconut dregs, tofu dregs and palm kernel cake. The function of this fermentation is to increase the nutrients contained in this material which will later be used as a growing medium for maggot and maggot is one of the alternatives to feed protein sources from fish meal. The study was conducted experimentally using a completely randomized design (CRD) 5 treatments and 4 replications, with the weight of each experimental unit the media content is 1 kg and filled with 1 g of BSF eggs and the media size is 37 cm long, 26 cm wide and 10 cm high. The parameters of this study consisted of maggot production and maggot nutritional content, namely moisture content, ash content, crude protein, crude fat and carbohydrates. Based on research results P0 (100% fermented rice bran) obtained an average maggot production of 525g, KA maggot 8,16%, KAb maggot 7,83%, PK maggot 44,82%, LK maggot 21,62% and 17.58% maggot carbohydrates respectively. P1 (50% fermented rice bran + 50% fermented coconut dregs) obtained an average maggot production of 467.5g, KA maggot 9,57%, KAb maggot 9,03%, PK maggot 44,68%, LK maggot 20,51% and 16.20% maggot carbohydrates respectively. P2 (50% fermented rice bran + 50% fermented tofu dregs) obtained an average maggot production of 545.25g, KA maggot 9,02%, KAb maggot 8,32%, PK maggot 44,74%, LK maggot 18,57% and 20.09% maggot carbohydrates respectively. P3 (50% fermented rice bran + 50% palm kernel cake) obtained an average maggot production of 542g, KA maggot 9,16%, KAb maggot 9,22%, PK maggot 43,72%, LK maggot 19,87% and 18.02% maggot carbohydrates respectively. P4 (25% fermented rice bran + 25% fermented tofu dregs + 25% fermented coconut dregs + 25% palm kernel cake) obtained an average maggot production of 831.5g, KA maggot 9,08%, KAb maggot 9,35%, PK maggot 44,38%, LK maggot 17,01% and 20.18% maggot carbohydrates respectively. From the research results, it can be concluded that the use of culture media with a combination of 25% fermented rice bran + 25% fermented coconut dregs + 25% fermented tofu dregs + 25% fermented palm kernel meal is the best combination where the production reaches 831.5 g bsf and 20 carbohydrates. , 18% but could not increase moisture content, ash content, crude protein and crude fat.
