Sex-Positive Curricula: An Investigation of the Relationship Between Physical Fitness, Self-Concept and Sexual Functioning

Despite the well-recognized benefits of exercise, Americans are gaining weight in astounding proportions and levels of physical activity are on the decline. The purpose of this study was to investigate a relationship between physical fitness, self-concept and sexual health. There is a dearth of knowledge on this relationship specifically in the context of sex-negative curricula, which is the dominate discourse in the United States. One hundred and thirty-three participants between the ages of 18 - 50 volunteered for fitness testing and data collection. Physical fitness was assessed through body fat, resting metabolic rate, cardiovascular endurance, muscular strength, muscular endurance and flexibility. Self-reported exercise was measured using the International Physical Activity Questionnaire. Self-concept was measured by the Six Factor Self-Concept Scale, which presented a total self-concept score and as six individual concepts of self (likability, morality, task accomplishment, giftedness, power and vulnerability). Additionally, sexual function was measured by Derogatis Interview for Sexual Functioning and presented as both an aggregate score and five separate constructs of sexual functioning (fantasy/cognition, arousal, orgasm, behavior/experience, and drive/desire). Questions pertaining to sexual partners, sex education, and demographic information were also included. The results of the General Linear Model indicated significant relationships between physical fitness, self-concept and total sexual functioning. The sexual behavior/experience of men was predicted by body fat percentage and flexibility. In women, behavior/experience was predicted by body fat percentage and arousal was predicted by cardiovascular endurance. Total self-concept was related to muscular endurance. When men were isolated in the analysis, likability was positively related to sexual behavior/experience, and task accomplishment was inversely related to sexual behavior/experience. In women, giftedness was related to cognition/fantasy, arousal, orgasm and total sexual functioning. No relationships were found between physical fitness and the number of sexual partners in men; however, both muscular strength and the power self-concept were significantly related to number of sexual partners in women. As a result of these findings, women may be inclined to exercise to improve arousal and sexual functioning. Furthermore, educators should note the findings of a positive relationship between physical and psychological health and sexual well-being because they provide support for the development and adoption of sex-positive curricula that incorporate potential benefits of sexual activity.

Towards flexible parsing of structured textual model representations

Existing parsers for textual model representation formats such as XMI and HUTN are unforgiving and fail upon even the smallest inconsistency between the structure and naming of metamodel elements and the contents of serialised models. In this paper, we demonstrate how a fuzzy parsing approach can transparently and automatically resolve a number of these inconsistencies, and how it can eventually turn XML into a human-readable and editable textual model representation format for particular classes of models.

Effects of truck traffic on top-down fatigue cracking performance of flexible pavements using a new mechanics-based analysis framework

The mechanics-based analysis framework predicts top-down fatigue cracking initiation time in asphalt concrete pavements by utilising fracture mechanics and mixture morphology-based property. To reduce the level of complexity involved, traffic data were characterised and incorporated into the framework using the equivalent single axle load (ESAL) approach. There is a concern that this kind of simplistic traffic characterisation might result in erroneous performance predictions and pavement structural designs. This paper integrates axle load spectra and other traffic characterisation parameters into the mechanics-based analysis framework and studies the impact these traffic characterisation parameters have on predicted fatigue cracking performance. The traffic characterisation inputs studied are traffic growth rate, axle load spectra, lateral wheel wander and volume adjustment factors. For this purpose, a traffic integration approach which incorporates Monte Carlo simulation and representative traffic characterisation inputs was developed. The significance of these traffic characterisation parameters was established by evaluating a number of field pavement sections. It is evident from the results that all the traffic characterisation parameters except truck wheel wander have been observed to have significant influence on predicted top-down fatigue cracking performance.

Flexible Power Control of Photovoltaic Plants Connected to Distribution Networks

This paper presents a system to control the power injected by a photovoltaic (PV) plant on the receiving network. This control is intended to mitigate some of the negative impacts that these units may produce on such networks, while increasing the installed power of the plant. The controlled parameters are the maximum allowed value of injected active power and the corresponding power factor, whose setpoints values may be fixed or dynamic. The developed system allows a local and a remote control. The injected power and the corresponding power factor may be set by following a predetermined profile or by real time adjustments to fulfill specific operation constraints on the receiving network. The system acts by adjusting the control parameters on the PV inverters. The main goal of the system is, in the end, to control the PV plant, ensuring the accomplishment of technical constraints and, at the same time, maximizing the installed power of the PV plant, which may be an important issue concerning the economic performance of such plants

ROLE OF THE FRONTAL EYE FIELD, SUPERIOR COLLICULUS, AND BASAL GANGLIA IN FLEXIBLE SACCADE BEHAVIOR

A distributed network of cortical and subcortical brain regions mediates the control of voluntary behavior, but it is unclear how this complex system may flexibly shift between different behavioral events. This thesis describes the neurophysiological changes in several key nuclei across the brain during flexible behavior, using saccadic eye movements in rhesus macaque monkeys. We examined five nuclei critical for saccade initiation and modulation: the frontal eye field (FEF) in the cerebral cortex, the subthalamic nucleus (STN), caudate nucleus (CD), and substantia nigra pars reticulata (SNr) in the basal ganglia (BG), and the superior colliculus (SC) in the midbrain. The first study tested whether a ‘threshold’ theory of how neuronal activity cues saccade initiation is consistent with the flexible control of behavior. The theory suggests there is a fixed level of FEF and SC neuronal activation at which saccades are initiated. Our results provide strong evidence against a fixed saccade threshold in either structure during flexible behavior, and indicate that threshold variability might depend on the level of inhibitory signals applied to the FEF or SC. The next two studies investigated the BG network as a likely candidate to modulate a saccade initiation mechanism, based on strong inhibitory output signals from the BG to the FEF and SC. We investigated the STN and CD (BG input), and the SNr (BG oculomotor output) to examine changes across the BG network. This revealed robust task-contingent shifts in BG signaling (Chapter 3), which uniquely impacted saccade initiation according to behavioral condition (Chapters 3 and 4). The thesis concludes with a published short review of the mechanistic effects of BG deep brain stimulation (Chapter 5), and a general discussion including proof of concept saccade behavioral changes in an MPTP-induced Parkinsonian model (Chapter 6). The studies presented here demonstrate that the conditions for saccade initiation by the FEF and SC vary according to behavioral condition, while simultaneously, large-scale task dependent shifts occur in BG signaling consistent with the observed modulation of FEF and SC activity. Taken together, these describe a mechanistic framework by which the cortico-BG loop may contribute to the flexible control of behavior.

Education for Sustainable Development in Norwegian Geography curricula

In Norway, environmental education (EE) has been part of schools’ curricula since the 1970s. The concept of education for sustainable development (ESD) was introduced after Agenda 21 was introduced at the UN conference on environment and development held in Rio in 1992. The article shows there has been little change in the geography curricula since the concept ESD was introduced, and no important differences are found between curricula for mandatory schooling (classes 1–10) and curricula for upper secondary schools. ESD is mentioned in the geography curricula but without explanation and implementation. Core goals in the general national core curricula may indicate a change to ESD, but they have not been followed in the development of geography curricula in Norway.

Staff and students co-creating curricula in UK higher education: exploring process and evidencing value

Student engagement in learning and teaching is receiving a growing level of interest from policy makers, researchers, and practitioners. This includes opportunities for staff and students to co-create curricula, yet there are few examples within current literature which describe and critique this form of staff-student collaboration (Bovill (2013a), Healey et al (2014), Cook-Sather et al (2014). The competing agendas of neoliberalism and critical, radical pedagogies influence the policy and practice of staff and students co-creating curricula and, consequently, attempt to appropriate the purpose of it in different ways. Using case-based research methodology, my study presents analysis of staff and students co-creating curricula within seven universities. This includes 17 examples of practice across 14 disciplines. Using an inductive approach, I have examined issues relating to definitions of practice, conceptualisations of curricula, perceptions of value, and the relationship between practice and institutional strategy. I draw upon an interdisciplinary body of literature to provide the conceptual foundations for my research. This has been necessary to address the complexity of practice and includes literature relating to student engagement in learning and teaching, conceptual models of curriculum in higher education, approaches to evidencing value and impact, and critical theory and radical pedagogies. The study makes specific contributions to the wider scholarly debate by highlighting the importance of dialogue and conversational scholarship as well as identifying with participants what matters as well as what works as a means to evidence the value of collaborations. It also presents evidence of a new model of co-creating curricula and additional approaches to conceptualising curricula to facilitate collaboration. Analysis of macro and micro level data shows enactment of dialogic pedagogies within contexts of technical-rational strategy formation and implementation.

BM: Efectos de una política cambiaria de tipo fijo frente a una política cambiaria flexible sobre la inflación en Colombia : 1977 -1992

Frente a la política de apertura comercial que se viene desarrollando desde 1990 en Colombia, el manejo económico ha tenido como propósito fundamental lograr integrar la economía nacional al exterior. Una de las herramientas de política económica más importantes es la TASA DE CAMBIO; frente a ésta, es preciso adoptar una posición y conocer el manejo que se le ha dado a esta variable durante los últimos veinte años. A partir de 1967, la política cambiaría colombiana se basó en un sistema de devaluación gota a gota (Crawling Peg). Esta política continuó hasta 1991, cuando la Junta Monetaria cambió la devaluación gota a gota, por el sistema de Certificado de Cambio con descuento. En enero de 1994, la nueva Junta Directiva del Banco de la República eliminó el sistema de certificado de cambio con descuento e introdujo el sistema de Bandas Cambiarías

Spirituality in the Undergraduate Curricula of Nursing Schools in Portugal and São Paulo-Brazil

Spirituality is considered a dimension of nursing care, which is often recognized as being neglected, mainly due to a lack of education. Several studies have addressed nursing students’ perceptions and skills for providing spiritual care, but there is little evidence on how spirituality is addressed in undergraduate nursing curricula. This study comprised Portuguese and Brazilian nursing schools (from São Paulo) and describes how spirituality is addressed in undergraduate nursing curricula. It is descriptive and the survey research was performed in 2014–2015. The questionnaire was composed of closed and open-ended questions and was sent by e-mail. A total of 129 answers were obtained, mostly from Portugal. Results indicated that several curricular units include spirituality, although having different contents. The learning outcomes are consistent with improving nursing students’ integral education, developing the clinical reasoning regarding spirituality, and improving the assessment of the patient across the life span. Nevertheless, it seems that spirituality is poorly addressed in clinical practice. Few nursing schools have courses or curricular units specifically dealing with spirituality, but they do provide some form of teaching on the subject. No standard curriculum exists, but teachers believe that it is a very important subject that should be included in the courses taught.

Excited state energy surfaces of flexible emitters for thermally activated delayed fluorescence

Organic Light-Emitting Diodes (OLEDs) technology has matured over recent years, reaching the commercialization level and being used in various applications. The required efficiency can be achieved by transforming triplet excitons into singlet states via Reverse InterSystem Crossing (RISC), which a general mechanism called thermally activated delayed fluorescence (TADF). Two prototypical molecules in the field, 2CzBN and 4CzBN, Carbazole Benzonitrile (donor-acceptor) derivatives, possess similar energy gap between singlet and triplet (∆EST, a key parameter in the RISC rate), but different TADF performance. In this sense, other parameter must be considered to explain these different behaviors. In this work, we theoretically investigate 2CzBN and 4CzBN and address the problem of how flexible donor-acceptor (D-A) or donor-acceptor-donor (D-A-D) molecular architectures affect the nature of excited state, and the oscillator strength. Furthermore, we analyze the RISC rates as a function of the conformation of the carbazole side groups, considering the S0, S1, T1 and T2 states. The oscillator strength of 4CzBN is higher than of 2CzBN, which, in turn, is almost vanishing, resulting in only 4CzBN being a TADF active molecule. We also note the presence of a second triplet state T2 lower in energy than S1, and that the reorganization energies, associated to the RISC processes involving T1 and T2, are both important factor in differentiating the rates in 2CzBN and 4CzBN. However, the 4CzBN RISC rate from T2 to S1 is surprisingly high with respect to the one from T1 to S1, although, according to EL-Sayed rules, since T2 (CT/LE) is more similar to S1 (CT) than in 2CzBN (LE, CT), this transition should be less favored. These insights are important to understand the photophysics of the TADF process and to design novel TADF emitters based on the benzo-carbazole architecture.
