Doctoral writing as an assemblage in space and time

ABSTRACT This article responds to the question, ‘how do doctoral students experience writing within space and time? ’ Whilst existing studies have understood academic writing to be a social and embodied practice, few have considered the material and temporal assemblages that facilitate everyday experiences of academic writing. Working from a new materialist ontological approach, this article draws on photovoice interviews with 11 doctoral students. Using ‘affect’ as the unit of analysis, the article explores the capacity of space, materiality and time to affect, and be affected by, experiences of writing. People, things, environment, and emotion all play a role in this ‘spacetimemattering’ and mean that experiences of writing are not processal, nor homogenous, but rather are ever-shifting assemblages of intra-actions. The article concludes with recommendations that attempt to shift our conceptualisation of doctoral writing, with writing being ultimately critical to doctoral success. In addition, it adds to the emerging literature that applies new materialist theory to studies in higher education.
Theoretical Estimation of the Frictional Energy Dissipation in a Simple Lap Joint

Some recent work on fretting fatigue in lap joints has shown that certain treatments of the joint contact surfaces greatly improve the fatigue life of the joint, and suggests that maximum benefit may be obtained by arranging for force transference within the joint to take place only by frictional resistance.A simple theoretical analysis of a simple lap joint is here presented which estimates the frictional energy dissipation, and concludes that, for any pressure distribution imposed along the joint faces by the rivet clamping force, the damping capacity of the joint is a maximum when force transference is only by friction throughout the joint.
Optimal Design of Gravity-Fed Looped Water Distribution Networks Considering the Resilience Index

The optimization of looped water distribution networks (WDN) implies achieving the best tradeoff between reliability and cost. Many works have dealt with minimizing the cost, but few have considered both cost and reliability. This paper aims to evaluate the performance of several multiobjective metaheuristics (MOMHs) to optimize the design of looped water distribution networks, taking into consideration two objective functions: Minimizing costs and maximizing the resilience index. The MOMHs used are: Strength Pareto Evolutionary Algorithm 2 (SPEA2), Pareto Archived Evolution Strategy, Pareto Envelope-based Selection Algorithm, Pareto Simulated Annealing, and Multiobjective Simulated Annealing and Tabu Search. These algorithms are tested and compared by applying them to two case studies: The first is a small well-known benchmark network (Hanoi), whereas the second one is a larger looped irrigation network (Balerma). Results of this work show that SPEA2 outperforms the remaining methods in terms of Pareto d.
Marie Antoinette Syndrome

Marie Antoinette syndrome (Canities subita) can be defined by the sudden graying of a person's hair as a result of extreme stress, trauma or an illness. It was named after Marie Antoinette, the French queen whose hair turned white overnight until she was guillotined in 1793 during the French Revolution. Marie Antoinette, who was dethroned by the revolution, she knew that she would be executed by a guillotine, so her hair suddenly turned white while in prison due to excessive stress. Cases of sudden graying due to stress and trauma have been documented many times since over 200 years. These cases have been classified in terms of area affected, age, gender, cause of illness, and concomitant diseases, and were named Marie Antoinette syndrome for the first time in 2009. In Latin, it has been named Canities subita by using the words' ani (subita) and whitening (Canities). Although its molecular mechanism has not been clearly resolved, various hypotheses have been put forward by researchers. These are related to the rapid destruction of pigments in the hair, abnormalities that have occurred in the scalp, or the mechanisms of body defense cells that affect pigment oogenesis. Marie Antoinette syndrome, which is a very rapid whitening of hair, eyelashes, eyebrows or other body hair, can be triggered by bodily illnesses, severe psychological illnesses, emotional stress or severe trauma caused by an event. Nowadays, data on this disease are limited, and it is a subject open to research for the medical world.

Changes in morphological and biochemical blood parameters in the postoperative period in experimental orthopedic surgeries in rabbits, treated with bone marrow aspirate, platelet-rich plasma and hydroxyapatite

T he evaluation of the morphological and biochemical blood parameters is extremely helpful after orthopedic procedures as it could be used as an indicator for the quality of the regeneration process. There were significant changes in the RBC count, amount of Hb and Hct in the postoperative period. We observed an increase in the total number of platelets as a result of the soft tissue and bone trauma, destruction of blood vessels, etc. All the changes in the post-surgical period regarding the biochemical parameters reflect the changes that occur in the macro-organism after anesthesia and surgery. Serum alkaline phosphatase differences in all groups is because of different activation of osteoblasts, producing specific bone alkaline phosphatase.
Musicpainter: a Collaborative Composing Environment

This thesis presents the design and implementation of Musicpainter, a networked graphical composing environment that encourages sharing and collaboration within the composing process. Instead of building a computer-assisted composing tool, Musicpainter aims to provide a social environment where users can gather and learn from each other. Our approach is based on sharing and managing music creation in small and large scale. At the small scale, users are encouraged to begin composing by conceiving small musical ideas, such as melodic or rhythmic fragments, all of which are collected and made available to all users as a shared composing resource. The collection provides a dynamic source of composing material that can be directly reused and it inspires users with more ideas. At the large scale, users can access full compositions that are shared as open projects. Users can listen to and change any piece if they want. The system generates an attribution list on the edited piece and thus allows users to trace how a piece evolves in the environment. Shared resource and open projects form the foundation of the social environment, and they create an opportunity for users to compose in a collaborative manner. A pilot study is conducted to verify our design. Thirty users downloaded the program and contributed a total of 90 partial or complete compositions. The statistics of basic user usage, a summary of user survey, and an analysis of the compositions created by selected users are presented in the thesis. Thesis supervisor: Barry L. Vercoe, D.M.A. Title: Professor of Media Arts and Sciences

Spatial and regional directory of wild Auricularia species found in the forest of Southwest Nigeria

The African forest, which was and still is the heart of biodiversity, is fast losing its bio-components due to natural disasters and human encroachment. A catalogue of the bio-components of the African forest is imminent so that conservation programs can be established to safeguard rare germplasm(s) from extinction. The population density of wild Auricularia (Mushroom) of Southwestern Nigeria was the focus of this research. DNA primers were obtained from Operon Technology, Alameda, California, USA. Characterization was done using phenotype, PCR and electrophoresis gel (RAPD). OPB-11 to OPB-21, OPH-3 to OPH-15, and OPT-1 to OPT-19 primers formed polymorphic bands with DNA samples of the specimens. Three (3) distinct species of Auricularia were identified in the forest of Southwest Nigeria based on PCR and RAPD analyses. Geospatial analysis showed that Auricularia auricula was present in the forests of Ekiti, Osun, Ogun, Oyo and Lagos states, but none was identified in Ondo State. On the contrary, Auricularia polytricha was only identified in the tropical rainforest and grassland vegetation of Ondo, Lagos and Oyo states. Key words: Auricularia, mushrooms, population density, Southwestern Nigeria, phenotypic description, genome similarity index.

The Influence of Leadership Styles on the Effectiveness of the Public Policy Implementation Process in Ethiopia: The Case of Addis Ababa City Government

Policy implementation desires the increased commitment and coordination of applicable stakeholders or actors. Policy implementation gap also emanates from leadership development practice because; leadership development and an appointment done through political appointments, rather than career posts depend on the leader's competencies. This study tried to investigate the relationship between specific leadership styles and the effectiveness of the policy implementation process. It is justifiable to conduct this study to contribute and cover the gap in relation to leadership style and policy implementation. This study aimed to explore the influence of leaders' leadership styles on the effectiveness of the policy implementation process in selected government public sectors in Addis Ababa City Government. The study was focused on well know leadership styles i.e., transformational, transactional, and laissez-faire, and the major variables that measure the implementation process effectiveness of policies i.e., policy-practice alignment, stakeholder engagement, active implementation or communication, ongoing evaluation and support, and transparency. The study was employed a descriptive survey design that uses a cross-sectional survey methodology. Primary data were collected from 237 individuals through closed ended questionnaire. The sample was selected using a simple random sampling method. The data analyzed by descriptive statistics (percentages, mean, and standard deviation) and inferential statistics (Pearson Product Moment correlation and multiple regressions). Predominantly the results of the study indicate the transformational leadership style was positively and significantly influences policy implementation process effectiveness (sig = 0.000 at p < 0.05). Both transactional (sig = 0.105 at p < 0.05) and Laissez-Faire (sig .957 at p < 0.05) Leadership Style have no statistically significance influence on implementation process effectiveness of policies. Surprisingly, the Laissez-Faire Leadership Style has a statistically insignificant negative influence on the policy implementation process. The study concludes that, if leaders exhibited a transformational leadership style, they could contribute more to the effectiveness of the policy implementation process than transactional and Laissez-Faire Style. It implies that leadership is responsible for the implementation of policies. The study mainly recommends leaders of government public sectors of Addis Ababa City Government to give due emphasis to appropriate leadership style as context as.
High Performance Al Ga As/GaAs HBT's

AlGaAs emitter heterojunction bipolar transistors (HBT's) are demonstrated to have excellent dc and RF prop- erties comparable to InGaP/GaAs HBT's by increasing the Al composition. Al Ga As/GaAs HBT's exhibit very high dc current gain at all bias levels, exceeding 140 at 25 A/cm and reaching a maximum of 210 at 26 kA/cm ( m m, ). The temperature dependence of the peak dc current gain is also significantly improved by increasing the AlGaAs mole fraction of the emitter. Device analysis suggests that a larger emitter energy-gap contributes to the improved device performance by both lowering space charge recombination and increasing the barrier to reverse hole injection.
Genetic Variability, Heritability and Genetic Advance of Groundnut (Arachis hypogaea L.) Genotypes at Assosa and Kamashi, Western Ethiopia

The lowland areas of Ethiopia have significant potential for increased oil crop production including groundnut. In Benishangul Gumuz Region, groundnut is cultivated in various zones and woredas under rain fed condition. However, due to insufficient improved groundnut varieties found in the region the productivity was low. Testing genotypes for the presence of variations and generation of genetic information is the first step in plant breeding to develop varieties for the targeted area of production. Keeping these in account the current study was conducted with the objectives of determining the genetic variability and trait association and their direct and indirect effects on yield and yield related traits of groundnut genotypes at Assosa and Kamashi zones, Western Ethiopia. Twenty five groundnut genotypes were evaluated in 5 x 5 triple lattice designs. Data were recorded for 16 traits and subjected to ANOVA using SAS software. Further genetic analyses were conducted as per the formula suggested by biometricians. Analyses of variance showed mean square due to genotypes were highly significant (p≤0.01) for all traits studied except seeds pod-1 at both locations. High heritability value coupled with high genetic advance as percent of mean was observed for primary branches plant-1, 100-seed weight, dry pod yield and grain yield hectare-1 at Assosa and Kamashi. Therefore, the current study revealed the presence of considerable variability for most of the traits studied and differences in the performance of the genotypes as there were significant differences among genotypes. Emphasis should be given for dry pod yield hectare-1, primary branches plant-1, pods plant-1 and 100-seed weight to enhance grain yield production.
A Comparison of Manual and Vocal Response Modes for the Control of Aircraft Systems

The objective of this study was to determine how a vocal response mode compared to a manual response mode for data entry in a fighter cockpit simulator. Specifically, both vocal and manual response modes were compared in single and dual task conditions on the basis of pilot flight performance, response time, and errors while accomplishing several communication, navigation, and weapons tasks. The results indicated that the manual response mode was more effective than the vocal response mode in terms of response time data; however, the vocal response mode was more effective in terms of flying performance data.
EFFECT OF HOUSING AND ENVIRONMENTAL ENRICHMENT ON PERFORMANCE AND BEHAVIOUR IN FATTENING RABBITS

Aim of this research was to test the effect of housing and environmental enrichment (presence of a wood stick inside the cage) on the performance and behaviour of fattening rabbits. The trial was carried out in a commercial farm, in the North-West of Italy (Lombardia region, Bergamo province). 72 rabbits were housed after the weaning period, at 35 days of age, in standard fattening cages at 2, 3, 4 animals per cage, (density: 1045 cm 2 , 697 cm 2 and 522 cm 2 respectively) . Half cages were enriched using a wood stick (robinia pseudoacacia) hanging from the ceiling of the cage. The animals were fed ad libitum a commercial feed, and were weighted at 35, 55 and 75 days of age and slaughtered at 75 days of age under commercial conditions. Behaviour was video recorded at the beginning (1 st period of observation) and at the end of the fattening period (2 nd peri od of observation), 24 hours for each period. Thus each cage was observed 48 hours in total (288 scans per cage). No significant differences were found in any selected productive parameter (live weight, daily weight gain) among treatment groups. In detail, the live weight at slaughtering (75 days of age) was: 2626, 2540g for animals housed without and with environmental enrichment respectively; 2597, 2562 and 2592g for animals housed at 2 -3-4 subjects per cage respectively. The animals’ housing significantly affected the rabbits’ behaviour. In fact, animals housed 2 per cage showed a higher variety of natural behaviours. The environmental enrichment affected the behaviour and not the performance. In fact, it decreases both oral stereotypies such as gnawing the bars of the cage, and alert, aggressive behaviour and self-grooming. This might indicate a better satisfaction of the behavioural needs for the enriched caged rabbits, while the other ones may spend more time inactive and/or performing abnormal behaviours and consequently may show higher stress levels due to the frustration in a hypo-stimulating environment.
Pre-tuned ridge regression and its extension to generalized linear models

Ridge regression is regularization or shrinkage method and a common approach in dealing with multicollinearity in conventional regression analysis. Ridge regression is widely used by statistical analyst since it is one of the best compared to other regularization methods. Also, the introduction of high dimension and ultra-high dimensional data has become an issue of concern and ridge regression is one way of dealing with such data. One of the key issues associated with ridge regression is the determination of the tuning or ridge parameter. The common practice is to fit ridge regression for a different number of values of tuning parameter before selecting the best tuning parameter. Our question is instead of fitting ridge regression for a number of different values of the tuning parameter before selecting the best tuning parameter via minimum GCV or other selection criterion, can the optimal tuning parameter be determined directly using without computing the estimated regression coefficients for each tuning parameter? The goal of this study is to put forward a shortcut method for conducting ridge regression. The main idea is to first estimate the best tuning parameter in ridge regression directly and compute their respective fitted values accordingly. For this reason, we call the proposed method as ‘pre-tuned ridge regression’. The objective function naturally becomes an estimating equation of tuning parameter which allows us to formulate selection of the tuning parameter as an estimation problem. In our method, the best choice of tuning parameter can be found beforehand and this is a one-dimensional smooth optimization problem. These modifications would shorten the computational time and improve the fitting performance as we will demonstrate. We will also extend our proposed method to generalized linear models.
