The deformation complex is a homotopy invariant of a homotopy algebra

To a homotopy algebra one may associate its deformation complex, which is naturally a differential graded Lie algebra. We show that infinity quasi-isomorphic homotopy algebras have L-infinity quasi-isomorphic deformation complexes by an explicit construction.Comment: A revised version.

Aerobic Fitness Benefits of a Community-Based Activity Program that Promotes Functional Outcomes for People with Spinal Cord Injury

The aim of the work presented in this thesis was to classify physical activities performed as part of a community-embedded, activity-based restorative therapy (ABRT) program for people with a spinal cord injury (SCI). This thesis also aimed to determine whether the intensity and duration of activity performed by participants during their regular ABRT were sufficient to meet current American College of Sports Medicine (ACSM) physical activity (PA) guidelines for developing and maintaining cardiorespiratory fitness and general health. Twenty-one regular clients of an Australian ABRT program (Walk On®) had their heart rate (HR) recorded and an observational time-and-motion analysis conducted during their regular therapy sessions over two successive one-week periods. The time and motion analysis included classification of each movement (1-9 schema), and ratings of perceived exertion (RPE) given by both the client and an independent observer for each exercise movement performed during a session of approximately two hours. Clients also completed a multi-stage, sub-maximal assessment on an arm crank ergometer followed by progressive, incremental exercise to volitional fatigue to determine submaximal and peak oxygen consumptions (VO2). The HR and VO2 relationship during arm cranking was then used to estimate VO2 values from HR recorded during ABRT sessions. The average intensity and total duration of ABRT exercises that clients performed as part of their regular therapy was compared with The ACSM PA guidelines for improving cardiorespiratory fitness and general health. The weekly average intensity x total duration of therapy sessions were statistically contrasted with ‘cut-points’ for “moderate” and “vigorous” exercise using percentage of HR maximum (%HRmax), percentage of heart rate reserve (%HRR), percentage of VO2 reserve (%VO2R) and self-reported RPE. For individuals with paraplegia (n=5) and tetraplegia (n=16) combined, arm cranking VO2peak was 13.2 ± 4.2 ml•kg-1•min-1 achieved at 38.4 ± 11.8 W power output, and there was no significant difference between the two groups. When comparing total volume (intensity x duration x frequency) of physical activities comprising ABRT, there were four results that indicated that participant activity was significantly below the guidelines for improving and maintaining health (i.e. moderate and vigorous absolute %HRmax and moderate and vigorous %HRR were below ACSM ‘cut points’). By contrast there was one intensity measure that significantly exceeded ACSM guidelines (moderate RPE was above RPE ‘cut points’). Finally, there were three variables (moderate and vigorous %VO2R and vigorous RPE) for which no definitive conclusion could be drawn as to whether average weekly ABRT was of sufficient intensity and duration to meet the current guidelines. Twelve of the 21 participants achieved > 500 MET•min-1 of activity over the two, one-week periods that were measured (mean: 482 ± 247 MET•min-1 per week), but this result was not statistically significant (p = 0.76). There was poor correlation between HR and either participant RPE (R2 = 0.08, p < 0.01) or observer RPE (R2 = 0.12, p < 0.01). This was consistent across each individual exercise classified with an activity code. This study demonstrated that ABRT was generally unlikely to be of sufficient intensity and duration to satisfy current ACSM physical activity guidelines for developing and maintaining cardiorespiratory fitness and general health in individuals with SCI, however these results were not consistent across all clients in the study. The different activities used as part of ABRT were classified and mean values were determined for their intensity and duration. These data suggest that, based on sufficient intensity and duration of weekly exercise, a community-based ABRT program may not meet current guidelines for health. Results highlighted the need for additional ‘dose-potent’ physical activity either within current ABRT programs or gained via supplementary methods

Business Management Programme as a Driver of Graduate Employability: A Critical Analysis of Perceptions of Students at a Selected University

The main purpose of this study was to establish and critically analyse the perceptions of final year students on the extent to which the business management programme enhances graduate employability in Botswana. Extant literature alludes to the fact that ensuring employability connotes a situation where a graduate of a curriculum is not only able to gain employment but also to maintain that employment. The study used the CareerEDGE model to explain the anatomy of employability as well as to articulate the extent of preparedness for employment that is required for a Business Management student to be able to meet the requirements of the labour market. Using a selected university, a simple random sampling strategy was used to select 92 students to participate in the study. A descriptive research strategy that employed a structured questionnaire for data collection was used. Results of the study showed that studied most of the final year Business Management degree students were of the view that the curriculum enabled them to be employed in two main sectors namely; private sector and public sector specifically in teaching jobs rather than in other sectors such as mining, commerce and agriculture. These results therefore showed that the business management programme is effective as a driver of employability in relevant business sectors, meaning that a relook at the curriculum may be needed for purposes of enhancing it.

Twistor theory of symplectic manifolds

This article is a contribution to the understanding of the geometry of the twistor space of a symplectic manifold. We consider the bundle $Z$ with fibre the Siegel domain Sp(2n,R)/U(n) existing over any given symplectic 2n-manifold M. Then, after recalling the construction of the almost complex structure induced on $Z$ by a symplectic connection on M, we study and find some specific properties of both. We show a few examples of twistor spaces, develop the interplay with the symplectomorphisms of M, find some results about a natural almost Hermitian structure on $Z$ and finally prove its n+1-holomorphic completeness. We end by proving a vanishing theorem about the Penrose transform.Comment: 34 page

Twistor spaces of generalized complex structures

The twistor construction is applied for obtaining examples of generalized complex structures (in the sense of N. Hitchin) that are not induced by a complex or a symplectic structure.Comment: revised version, 17 pages; corrected typos, added references, minor stylistic changes in the expositio

Looking for genre: the use of structural features during search tasks with Wikipedia

This paper reports on our task-based observational, logged, questionnaire study and analysis of ocular behavior pertaining to the interaction of structural features of text in Wikipedia using eye tracking. We set natural and realistic tasks searching Wikipedia online focusing on examining which features and strategies (skimming or scanning) were the most important for the participants to complete their tasks. Our research, carried out on a group of 30 participants, highlighted their interactions with the structural areas within Wikipedia articles, the visual cues and features perceived during the searching of the Wiki text. We collected questionnaire and ocular behavior (fixation metrics) data to highlight the ways in which people view the features in the articles. We found that our participants’ extensively interacted with layout features, such as tables, titles, bullet lists, contents lists, information boxes, and references. The eye tracking results showed that participants used the format and layout features and they also highlighted them as important. They were able to navigate to useful information consistently, and they were an effective means of locating relevant information for the completion of their tasks with some success. This work presents results which contribute to the long-term goals of studying the features for genre and theoretical perception research

Desigualdad de género en el mercado laboral fronterizo Chile-Perú entre mujeres venezolanas inmigrantes

The objective of this study was to explore the perceptions of Venezuelan migrant women in relation to gender inequality in the Chile-Peru border labor market, 2022. Mixed, descriptive, and analytical research. The study was conducted in the cities of Arica-Chile and Tacna-Peru during the months of October-December 2022. The inclusion criteria corresponded to Venezuelan immigrant women, over 18 years of age, who had worked in the receiving country in the last 3 years. The sample size was 212 participants; the sampling method was by convenience and snowball. Several statistical analysis methods were used in the study: 1.- Descriptive statistical analysis, reliability analysis, and exploratory factor analysis. The instruments used correspond to: Perception of gender inequality modified from the Memon and Jena (2017) and ILO (2008) scale and the Psychological Well-Being Scale, in its short version (EBS-8). The results indicated, based on the "Perception of Gender Inequality" scale, that the group believes they are disadvantaged ("Ingroup Disadvantage Dimension"), perceive privilege in the outgroup ("Outgroup Privilege" Dimension), have past experiences of inequality ("Past Experience of Gender Inequality" Dimension) and face prejudice in the context ("Prejudice in Context Dimension"), in addition, the "Subjective Psychological Well-Being" scale expressed that the group has a moderate to high perception of their well-being.El objetivo de este estudio fue explorar las percepciones de mujeres migrantes venezolanas, en relación a la desigualdad de género en el mercado laboral fronterizo Chile-Perú, 2022.

La nueva experiencia Selvámonos en la gestión del entretenimiento cultural

La gestión del cliente actualmente pasó de ser importante a ser imprescindible debido a la competencia agresiva y a los cambios tecnológicos lo que conlleva a dedicarle mayor énfasis a los diversos canales de comunicación que tiene una empresa. El rubro de gestión cultural no está exento de ello, ya que nuestro país, a diferencia de países vecinos de la región, invierte en cultura el 0.35% del presupuesto anual y que según proyecciones hacía el bicentenario, 2021, las industrias culturales representarían el 5% del PBI. En el Perú existen diversas empresas privadas o asociaciones que están invirtiendo en difundir cultura como lo son las artes escénicas y la música. Selvámonos ha cumplido 10 años en el mercado nacional, impulsando la cultura realizando un promedio de 70 eventos durante el año. Se destacan 3 festivales principales: Electro Selvámonos, Primera Parada y el Festival Selvámonos este último dura una semana en la ciudad de Oxapampa, donde los pobladores pueden participar de talleres gratuitos de teatro, pintura y música, para adultos y niños. Teniendo como cierre el festival musical que congrega a diversos artistas del Perú y del mundo, donde la concurrencia cada vez es mayor y el exceso descomunal a las comisiones de las ticketeras, sumado a la nula estrategia de relación con el cliente, pone en peligro el futuro de la organización de Selvámonos. En el presente plan de negocios se propone el desarrollo de la nueva experiencia Selvámonos, convirtiéndola en una de las mejores productoras del Perú y Latinoamérica por ser sostenible en el tiempo y marcar un referente autogestionario en la región.Trabajo de investigaciónCampus Lima Centr
