Expressions of Human Sexuality in the Phallic and Latency Phases: Reports from a Field Observation in Children of Porto Velho, Brazil
The present study was conducted according to the Freudian subdivisions on human psychosexuality. The study on sexuality can be subdivided and directed to several themes, walking through several areas of knowledge, where each theoretical field contributes significantly to such study. This work was part of the studies of the discipline Human Sexuality of the Course of Psychology of the Federal University of RondĂ´nia in the second semester of 2017 and reports an observation made with four children, having as subjects children in the age group of 3 to 8 years, whose names used in this Freud's contributions to human sexuality, with emphasis on the phallic phase and latency period, are fictitious and based on theory. To assist in the field observations on the phases, a plan of observations was made with a script of aspects to be observed considering the literature that already indicates some characteristics attributed to this stage of human life. As a result, it was observed that there are clear correspondences between the literature and the practice, however, there is a need to broaden the means and resources of observation to deepen the research, producing, in turn, a better analytical apparatus
Adjustment of photosynthetic activity to drought and fluctuating light in wheat
Drought is a major cause of losses in crop yield. Under field conditions, plants exposed to drought are usually also experiencing rapid changes in light intensity. Accordingly, plants need to acclimate to both, drought and light stress. Two crucial mechanisms in plant acclimation to changes in light conditions comprise thylakoid protein phosphorylation and dissipation of light energy as heat by non-photochemical quenching (NPQ). Here, we analyzed the acclimation efficacy of two different wheat varieties, by applying fluctuating light for analysis of plants, which had been subjected to a slowly developing drought stress as it usually occurs in the field. This novel approach allowed us to distinguish four drought phases, which are critical for grain yield, and to discover acclimatory responses which are independent of photodamage. In short-term, under fluctuating light, the slowdown of NPQ relaxation adjusts the photosynthetic activity to the reduced metabolic capacity. In long-term, the photosynthetic machinery acquires a drought-specific configuration by changing the PSII-LHCII phosphorylation pattern together with protein stoichiometry. Therefore, the fine-tuning of NPQ relaxation and PSII-LHCII phosphorylation pattern represent promising traits for future crop breeding strategies
Reply to Komatsu et al.: From local social mindfulness to global sustainability efforts?
Komatsu et al. (1) argue that Van Doesum et al. (2)
may have overlooked the role of GDP in reporting a
positive association between social mindfulness
(SoMi) and the Environmental Performance Index
(EPI) at country level. Although the relationship
between EPI and SoMi is relatively weaker for countries with higher GDP, that does not imply that the
overall observed relationship is a statistical artifact.
Rather, it implies that GDP may be a moderator of
the relationship between EPI and SoMi. The
observed correlation is a valid result on average
across countries, and the actual effect size would, at
least to some degree, depend on GDP
Reply to Nielsen et al.: Social mindfulness is associated with countries' environmental performance and individual environmental concern.
Nielsen et al. (1) argue that Van Doesum et al. (2)
need to consider three points for their interpretation
of a positive association between individual-level
social mindfulness (SoMi) and environmental performance (EPI) at the country level (3). The association
is weaker when 1) it is controlled for GDP and 2)
when the data of three countries are removed; also,
3) the data do not address the association between
SoMi and individual-level environmental concern.
We discuss these points in turn
Social mindfulness and prosociality vary across the globe
Humans are social animals, but not everyone will be mindful of others to the same extent. Individual differences have been found, but would social mindfulness also be shaped by one’s location in the world? Expecting cross-national differences to exist, we examined if and how social mindfulness differs across countries. At little to no material cost, social mindfulness typically entails small acts of attention or kindness. Even though fairly common, such low-cost cooperation has received little empirical attention. Measuring social mindfulness across 31 samples from industrialized countries and regions (n = 8,354), we found considerable variation. Among selected country-level variables, greater social mindfulness was most strongly associated with countries’ better general performance on environmental protection. Together, our findings contribute to the literature on prosociality by targeting the kind of everyday cooperation that is more focused on communicating benevolence than on providing material benefits
Cervical lymph node metastasis in adenoid cystic carcinoma of the larynx: a collective international review
Adenoid cystic carcinoma (AdCC) of the head and neck is a well-recognized pathologic entity that rarely occurs in the larynx. Although the 5-year locoregional control rates are high, distant metastasis has a tendency to appear more than 5 years post treatment. Because AdCC of the larynx is uncommon, it is difficult to standardize a treatment protocol. One of the controversial points is the decision whether or not to perform an elective neck dissection on these patients. Because there is contradictory information about this issue, we have critically reviewed the literature from 1912 to 2015 on all reported cases of AdCC of the larynx in order to clarify this issue. During the most recent period of our review (1991-2015) with a more exact diagnosis of the tumor histology, 142 cases were observed of AdCC of the larynx, of which 91 patients had data pertaining to lymph node status. Eleven of the 91 patients (12.1%) had nodal metastasis and, based on this low proportion of patients, routine elective neck dissection is therefore not recommended
Transformations to groundwater sustainability: from individuals and pumps to communities and aquifers
If the success of agricultural intensification continues to rely on the depletion of aquifers and exploitation of (female) labour, transformations to groundwater sustainability will be impossible to achieve. Hence, the development of new groundwater imaginaries, based on alternative ways of organizing society-water relations is highly important. This paper argues that a comparative documentation of grass-roots initiatives to care for, share or recharge aquifers in places with acute resource pressures provides an important source of inspiration. Using a grounded anti-colonial and feminist approach, we combine an ethnographic documentation of groundwater practices with hydrogeological and engineering insights to enunciate, normatively assess and jointly learn from the knowledges, technologies and institutions that characterize such initiatives. Doing this usefully shifts the focus of planned efforts to regulate and govern groundwater away from government efforts to control individual pumping behaviours, to the identification of possibilities to anchor transformations to sustainability in collective action
