Women do not wear pink in Latin America : A study of the Pink Tide’s controversial legacy in gender equality in South America

Payva, Marisa January 2021 (has links)
The possibility to earn a living and support a family independently is still a utopia for many women all around the world. Many organizations are constantly fighting for awareness of these issues and strive for an improvement in women’s economic equality. One of these organizations is the Committee on the Elimination of Discrimination against Women (CEDAW) which in its preamble acknowledges that "discrimination violates the principles of equality of rights and respect for human dignity".By the tenth anniversary of the CEDAW, almost one hundred nations have agreed to be bound by its provision. Some governments have achieved their goals by replacing discriminatory laws and policies in order to guarantee gender equality. Others have even gone the extra mile by promoting legislation which in turn would make it easier for women to be able to develop their careers. For instance, some have provided longer maternity leave, and in a few exceptional cases, some others gave the possibility of joint parental leave, creating a co-responsibility between men and women. Nevertheless, some governments have not done enough to balance the gender gap. Some even keep discriminatory laws on the books despite having come to powerlifting the flag of social justice and gender equality. This has been the case of many of the so-called “Pink Tide governments” that ruled in the majority of South America during the first two decades of the 21st century. Despite the left turn of these governments, women in the region are still exposed to segregation and jobs with lower status or a lower payment. This paper focuses on this particular period of South American political history, with a focus on the government policies issued to fight the increasing gender gap on women's economic participation and opportunities. In order to account for the actions taken by these governments towards gender equality policies, we will analyze the maternity and parental leave laws implemented during this period, as we understand that women’s social and economic rights are closely related to their status and conditions at work. Finally, we argue that in this case, the color pink has not been representing women in Latin America.

Färgassociationer : Uppfattningar om och associationer till färgen rosa i ett såväl traditionellt som ett modernt, icke-traditionellt marknadsföringssammanhang

Lenas Jacobsson, Ludvig January 2023 (has links)
The purpose of this study is to examine the perceptions of and associations with the color pink in both a traditional and a modern non-traditional marketing context. That is, what traditional associations do people have with the color pink in contrast to what modern new associations have developed with the color pink as we see it today.The research question presented in the study is: “How is the use of the color pink perceived today in a marketing context in comparison to the traditional associations that the color has had historically?”  The theories of the study are: Associative learning, Sensory marketing and Brand theory. Furthermore, colors in marketing and traditional associations with the color pink are discussed. This is a qualitative study based on 31 semi-structured interviews conducted via face-to-face meeting, Zoom-meeting, and telephone call. The informants were selected based on a convenience sample.In conclusion the study indicates that shades of the color pink is the leading factor in shifting people's behavior toward the color and that currently the color pink represents a creative role in various marketing contexts.

Effect of Ca and pH on Disease Severity of Pink Rot Phytophthora erythroseptica in Russett Norkotah Potato Solanum tuberosum

Benson, Jared H. 08 July 2008 (has links) (PDF)
Phytophthora erythroseptica Pethyb. is a devastating fungal pathogen of potato (Solanum tuberosum). The pathogen causes a disease known as pink rot. Pink rot results in necrosis and decay of tubers; and is responsible for major losses pre and post harvest. Attributes of the disease are progressing toward epidemic proportions. To help prevent such dramatic outbreaks of the disease, understanding the factors associated with incidence will provide opportunities to control the pathogen. A link between pH and disease severity has been observed. We studied the effects of pH and Ca to determine their influence on disease development. Low pH and Ca deficiencies are often inter-related factors that can be causal of one another. The pH effect could be due to either H+ or Ca ions. To separate their interactive effects we tested each variable individually using hydroponics and nutrient solutions. We assessed disease severity by assigning an Infection Coefficient (IC) to each root and stolon samples. The IC values were determined by quantifying DNA and then creating a ratio of host to pathogen DNA within root tissue. The DNA was measured by quantitative RT PCR. Statistical analysis showed significance in greater pathogen presence at more acidic pH and lower levels of available Ca. Significant reductions in IC values were observed when pH was elevated above pH 7. There was a notable increase in colonizing pathogen DNA at pH 5. Ca was significant, and as levels of soluble Ca increased the degree of disease severity became smaller. The effect of Ca was found not to be dependent upon pH. These results suggest immediate and cost effective applied management strategies to reduce incidence and disease severity outbreaks. Amending the soil with lime to increase soil pH and Ca content is one such potential method.

The Effect of Color on Working Memory Performance

Galvez, Michelle 01 August 2015 (has links)
This paper explores the effect of color on working memory performance. Interest in Baker-Miller pink surged with the finding by Schauss (1979) that it reduced aggression in aggravated detainees. However, research behind Baker-Miller pink has been influenced by biases and methodological errors. Its effects are likely overstated. Red and blue have also been studied for their effects on creativity, approach-avoidance conflict, detail-orientation, and most importantly, stress. Further research has been conducted on the effects of relaxation on cognition, with the conclusion that increased relaxation leads to improvements in working memory performance. This paper tests the effect of color on working memory performance. Accuracy on the n-back was compared across 4 colors: pink, red, blue, and black. No significant differences in accuracy were found in any of the color conditions, though the main effect of load was significant. Future research can increase the sample size and utilize a cognitive task that is inherently stressful.

A pectin histochemical study of the host pathogen relationship between Pyrenochaeta terrestris and Allium cepa

Cobia, LeRoy Richard 01 August 1971 (has links)
The involvement of pectin and pectinases in the host pathogen interaction of P. terrestris and Allium cepa were investigated by use of pectin histochemical stains at the electron microscope level. Several different pectin histochemical stains were used, but only two (the hydroxylamine reaction, and the pectin stain developed in this study) gave reliable results. It was observed that by the time the fungus has reached the host cell wall pectinesterase and endoplygalacturonase have fully removed the pectin from the host cell wall. When this has occurred, cellulases are released which continue to degrade the host cell wall. Electron transparent areas appeared where there were no COOH groups.

Recevoir l’irrecevable : postures du spectateur dans Pink Flamingos (John Waters, 1972)

Molaison, Nathaël 20 April 2018 (has links)
Je m’intéresse à la figure du spectateur prévue par le film, à partir des travaux de Francesco Casetti, Roger Odin, Umberto Eco et Martin Lefebvre. Mon objectif est de montrer que la figure du spectateur est plurielle. Dans cette perspective, nous verrons que tout film fait une offre à son spectateur, mais que celui-ci y répond de manières différentes selon le contexte dans lequel il voit le film et les positions éthiques qu’il fait siennes. Le film Pink Flamingos, de John Waters (1972), cherche, par tous les moyens, à provoquer la sensation d’un dégoût intéressant. Il s’inscrit en faux contre l’institution du film de fiction traditionnel, puisqu’il propose au spectateur d’« interagir » avec lui. Nous verrons toutefois que cette proposition implique une distinction entre, pour simplifier, un « bon » et un « mauvais » spectateur, selon qu’il soit ou non participatif.

Biology, Captive Propagation, and Feasibility of Pearl Culture in the Pink Heelsplitter (Potamilus Alatus) (Say, 1817) (Bivalvia: Unionidae)

Hua, Dan 21 September 2005 (has links)
Pink heelsplitter (Potamilus alatus) mussels collected from Kentucky Lake, TN were held at two bottom locations (0.6 m, 2.5 m) and suspended in pocket nets (at depth about 1.0 - 1.5 m) in a pond at the Freshwater Mollusk Conservation Center (FMCC), Virginia Tech, for 1 yr. Survival of mussels after 1 yr was significantly different, with poorest survival (30 %) in the bottom of the deep end; and no difference between the shallow end (83.3 %) and the suspended pocket nets (63.3 %). Survival of mussels was inversely related to water temperature (r = - 0.72); lowest monthly survival occurred in summer, resulting in a significant difference among the three locations with a similar trend after 1 yr. The glycogen reserves of mussels in captivity for 1 yr differed by pond location, higher in mussels at the shallow end than those in suspended pocket nets and at the deep end. Therefore, the shallow end of pond was more suitable for holding mussels long-term, while the suspended pocket nets are an alternative site for holding captive mussels. Additionally, dissolved oxygen was very low at the deep end (1.9 mg/L) in summer, while it was adequate (range from 5.7 - 6.4 mg/L) at the location of suspended pocket nets, and 5.0 mg/L at the shallow end (24.7 °C). Data for 40 specimens indicated that sexual dimorphism in valve shape occurred in P. alatus. Female mussels had a significantly (p < 0.0001) greater ratio of height (H) to length (L) (52.3 %) and width (W) to length (31.8 %) than males (H/L: 48.4 %; W/L: 28.8 %), respectively. The posterior ends were somewhat round to oval in males and bluntly squared or truncated in females. Female mussels were more inflated than males. These morphological differences can be used to distinguish females from males during field collections. The red drum (Sciaenops ocellatus) was identified as a new fish host for P. alatus, as 48 active juveniles were transformed by this species, which is not a natural host. Four glochidia were observed on the fins versus 2,307 on the gills of five red drum. Freshwater drum also was verified as a suitable host fish, but black crappie (Pomoxis nigromaculatus), banded sculpin (Cottus carolinae), yellow perch (Perca flavescens) and nile tilapia (Oreochromis nilotica) did not support transformation of glochidia to juveniles. Survival and growth of propagated juveniles of P. alatus were assessed regarding the effects of algal diets (Nannochloropsis oculata and Neochloris oleoabundans) and substrate type (fine sediment and sand). Overall, survival of juveniles after 17 d ranged from 23.8 to 66.8 %, with mean of 48.5 %; however, survival dramatically declined during the next 2 wk period to only 5.8 % (range of 1.8 to 7.8 %). Survival rate of juveniles was significantly different (p = 0.027) between substrates, but not in diets (p = 0.520), with the lowest survival rate of 23.8 % in sand substrate and fed N. oculata. Juveniles grew faster in fine sediment (23.0 % increase in shell length) than in sand substrates (10.5 % increase) (p = 0.002). Moreover, mean growth rate of juveniles was 4.9 &#956;m/d during the first 2 wk, but decreased to 0.2 &#956;m/d in the remaining 2 wk. Therefore, fine sediments seemed more appropriate for juvenile culture compared to sands. Both species of algae, N. oculata and N. oleoabundans, can be used to feed juveniles in the laboratory. Adult pink heelsplitters were used to study feasibility of pearl production by using two surgical implants (non-nucleated implant = NNI, and image pearl implant = IPI) in two ponds of different nutrient levels (FMCC pond and Duck pond). NNI and IPI pearls with purple or purplish luster were successfully produced in P. alatus. Pearl weight was not significantly different (p = 0.562) between two ponds. No differences in monthly survival rates of mussels were observed in either pond (p = 0.051), or among mussels with surgical implants and the no-surgery control mussels (p = 0.881). Consequently, P. alatus can be considered a potential species for producing purple pearls in pearl culture. Additionally, mussels in the Duck pond had higher (p < 0.0001) glycogen levels, similar to those in wild collected mussels, than those in the FMCC pond, indicating that this pond environment may be more suited for holding implanted mussels in captivity. / Master of Science

Vägen till framgång : En kritisk diskursanalys av Bossbabes webbkommunikation

Lindskog, Ida, Nilsson, Julia January 2022 (has links)
Title: Road to success: A critical discourse analysis of Bossbabe's web communication  The aim of the study was to investigate and problematize how companies involved in coaching of women's entrepreneurship relate to and construct the discourse of success. The theoretical areas covered are individualisation and reintegration, the expert society, gender theory and gender roles, and relationship-building marketing. The study used critical discourse analysis and semiotics as a method to analyze screenshots from the Bossbabe company's website. From the analysis, findings emerged that Bossbabe challenges and reproduces norms of success. Visibility work was found to be mainly used as an additional source of income. Success was personified by Bossbabe both by showing experts as concrete symbols of success and by advocating a certain type of lifestyle. Bossbabe also uses relationship-building marketing such as pink marketing and word-of-mouth (WOM). From the analysis we see a pattern of reproduction and challenge of gender norms within the discourse of success.

TAXONOMIC STUDIES AND THE EVOLUTION OF HABITAT PREFERENCE IN THE CYSTOBASIDIOMYCETES

Pedro Pablo Parra Giraldo (7041446) 15 August 2019 (has links)
Pucciniomycotina is a subphylum with a high diversity in terms of habitat and life history strategies that include plant parasites, animal associates (including opportunistic human pathogens), saprobes and antagonists of other fungi. The class Cystobasidiomycetes within this subphylum is a representative of such diversity and remains understudied. Their role in nature and the associations they establish with their hosts for most of the species is still unknown. In this study we used taxonomic and phylogenetic methods to present an inventory of strains in this class collected for more than 20 years from all over the world and preserved in the Aime Lab Culture Collection. Molecular and morphological data for six new species in the genera <i>Bannoa, Buckleyzyma</i>, <i>Halobasidium</i> and <i>Sakaguchia </i>were also presented. Additionally, mating experiments were performed by pairing strains of <i>Bannoa</i>; this is the second time in the genus that clamp connections and basidia are observed. We also found that newly described species of <i>Bannoa</i> can be co-inhabitants of sori of rust fungi. In general, antagonistic interactions can occur through: 1) direct physical contact between two fungi, i.e., mycoparasitism; or, 2) the production of antimicrobial compounds. In the Cystobasidiomycetes, direct physical antagonistic interaction which is associated with sexual states has been reported in species of Cystobasidium, Naohidea, Cyphobasidium and Occultifur. On the other hand, the production of antimicrobial compounds which mainly occurs between the yeast stage of the fungi and other organisms has only been reported in Cystobasidium pallidumand Hasegawazyma lactosa. We also hypothesize that the common ancestor to Cystobasidiomycetes is a mycoparasite due to the fact that this life strategy is present in most of the lineages in the class. To test this hypothesis, we grouped into five categories the host association or substrate from which strains of extant species in the Cystobasidiomycetes were isolated, i.e.,animals, plants, fungi, aquatic or decaying organic matter. We constructed a resolved phylogeny for the class based on seven locito study the evolutionary origins of mycoparasitism through ancestral character reconstruction with representation of all described species. Our analysis suggests that the most likely hypothesis is that the most recent common ancestor of the Cystobasidiomycetes was associated to fungi.<br>
