Resumen

Reciprocal crosses were made among seven barley genotypes of diverse origin. Parents and 42 F1's were grown in a randomized block design with four replications in the greenhouse. Chlorophyll fluorescence activity of the penultimate leaf (below flag leaf) of the main stem at flowering were measured for each plant. Leaf blade area and its duration were also determined for the above-mentioned leaves. "Leaf blade area × leaf life duration" was also used as a trait. Results of diallel analysis showed that both general and specific combining abilities were significant for all the characters studied. General combining ability values and effects were usually more important than those of specific combining ability, showing the importance of additive genetic control for the traits. Reciprocal effects were significant only for chlorophyll fluorescence activity. Narrow sense heritability values for leaf area, leaf duration, and its chlorophyll fluorescence activity were 87.9, 66.8, and 77.4%, respectively. Key words: combining ability, reciprocal effect, heritability, fluorescence, leaf area.

Resumen

Anthurium andraeanum Hort. is an important tropical ornamental crop regarded as second only to orchids in its commercial importance. The genetic basis for productivity in anthurium was studied using parent–offspring regression analysis. Sixteen parental genotypes (4 years old) and 14 biparental progeny families (60 plants each, 4 years old) derived from the parents were used in the study. Yield expressed as number of cut flowers per plant per year (CFPY) was significant both between parental genotypes (P < 0.001) and between progeny families (P < 0.05). Mean CFPY of the parent genotypes was normally distributed and ranged from 4.8 in ‘Local Mina Red’ to 9.8 in ‘Kalapana’ with a mean of 7.5. CFPY in Year 1 was strongly correlated to that in Year 2 (Pearson’s r = 0.96; Spearman’s r = 0.93) and the broad sense heritability (H2) was high (87.6%) under controlled shadehouse conditions. CFPY in the progeny families varied from four to 14 with progeny means ranging from 5.7 in ‘Honduras/Local Mina Red’ to 7.2 in ‘Mirjam/Kalapana’. Progeny of seven and 10 crosses possessed mean CFPY greater than that of the more productive parent and the midparent values, respectively. The frequency distribution for productivity of the 840 progeny plants was skewed to the right with a modal class of six to seven. The correlation coefficient between progeny CFPY and midparent CFPY was large and significant (r = 0.90, P < 0.001). The regression of mean progeny CFPY on mean midparental CFPY was strong (y = 0.51x + 2.56; R2 = 0.81) with an estimated narrow sense heritability (h2) of 51.0%. A breeding strategy for improving per plant productivity based on the results is discussed.

Resumen

The effects of GCA samples according to the results of dialysis analysis are given. Genetic control systems of traits of each variety are reflected, in particular the relative contribution of dominant and recessive alleles. According to the analysis of the effects of general combinatorial ability, samples with high indicators were selected for most of the studied features: the number of vegetatively elongated shoots - Poltava 52; foliage - Anto; dry matter yield - Poltava 52; protein content in dry matter - Poltava 52; the number of generative shoots - Anto and Poltava 52; panicle length - Anto and Radio-mutant k-7; seed productivity - Anto. A high level of the coefficients of heredity of the studied signs in a broad sense (H2 = 0,93 – 0,99) have been established. The coefficients of heredity in the narrow sense (h2) in terms of genetic variability due to additive effects of genes were different. The highest rate was in seed productivity (0,91), the number of vegetatively elongated shoots (0,78), dry matter yield (0,70); the lowest - in the length of the panicle (0,35) and the height of the plant - (0,43). The protein content was average (0,58). Key words: unbearded hundred-spike, diallel crosses, general combination ability, heredity.

Resumen

This project examined rose (Rosa ×hybrida) performance by measuring flower size and flower numbers per inflorescence in spring, summer, and fall seasons (mean temperatures 21.7, 30.0, and 18.1 °C, respectively) in interrelated rose populations. Populations and progeny differed in flower size as expected. Heat stress in the summer season decreased flower diameter (18%), petal number (17% to 20%), and flower dry weight (32%). Analysis of variance (ANOVA) showed a significant population/progeny × heat stress interaction for flower diameter indicating that rose genotypes responded differentially to heat stress. Flower size traits had moderate low to moderate narrow-sense (0.38, 0.26–0.33, and 0.53 for flower diameter, petal number, and flower dry weight, respectively) and moderately high to high broad-sense (0.70, 0.85–0.91, and 0.88 for flower diameter, petal number, and flower dry weight, respectively) heritability. Genotype × environment (G × E) variance (population/progeny × heat stress) for flower diameter accounted for ≈35% of the total variance in the field experiment indicating that heat stress had moderate differential genotypic effects. However, the genetic variance was several fold greater than the G × E variance indicating selection for flower size would be effective in any season but for the selection of a stable flower size (heat tolerant) rose genotype, selection would be required in both the cool and warm seasons. Seasonal differences in flower productivity of new shoots did not appear related to heat stress but rather to the severity of pruning conducted in the different seasons. The number of flowers produced on the inflorescence had moderate narrow-sense (h2 = 0.43) and high broad-sense (H2 = 0.75) heritability with a moderate genotype × pruning effect that explained about 36% of the variance.

Resumen

Abstract The concept of sustainability and the feasibility options have been discussed in specialized literature sources for about three decades only. Sustainable development has several definitions; it is defined both in narrow and wider sense. The definition of sustainability is regarded inevitable because the sustainability of agriculture can be interpreted only within this fixed conceptual framework. Our study primarily deals with issues of sustainability in farming practices being specific to countries and regions of the European Union. In frames of the current research we provide the analysis of the ability to produce value added within agricultural sector, the intensity of farming, the non-renewable external input use, farm structure as well as the European-level relations being directed towards the preservation of land productivity.

Resumen

The survival, initial productivity, and the genetic parameters of Corymbia citriodora subsp. citriodora (CCC), Corymbia citriodora subsp. variegata (CCV), and Corymbia torelliana (CT) were used to develop a breeding strategy for the Corymbia species. Survival, height, and diameter at breast height (DBH) data were assessed 24 and 36 months after planting, and the mean annual volume increment was estimated in three trials. Longitudinal DBH data analysis was applied individually to each trial to identify the best and the poorest families at both ages. The mortality ranged from 5% in CT to 27% in CCC, and the mean annual increment varied from 17.8 to 20 m3·ha−1·year−1 at 36 months after planting. The 36-month narrow-sense heritability [Formula: see text] was high for CCV (0.69 ± 0.17), moderate for CCC (0.41 ± 0.11), and low for CT (0.21 ± 0.09). The genetic parameters indicated the need for different breeding strategies for each species. Selecting the best families while roguing the poor families allowed forward selection of CCC and CCV. It was possible to select good CT trees for hybrid breeding; however, improving the species population requires focusing on increasing the effective size and expanding the genetic variability in the CT population.

Resumen

Although an average plant height is more preferable in most of agronomic crops, less reduction of this trait in stress condition makes yield components and seed yield sustainable in rapeseed varieties. Combining ability, heterosis and heritability of plant height at application and non-application of nitrogen environments (Hp and Hs, respectively) and its related stress tolerance indices were detected in half F2 diallel crosses of six spring rapeseed varieties. Significant mean squares of general and specific combining abilities (GCA and SCA) were detected for Hp, Hs, mean productivity (MP), geometric mean productivity (GMP) and stress tolerance index (STI), indicating the importance of additive and non-additive genetic effects for them. A high narrow-sense heritability estimate was exhibited for STI, emphasizing the prime importance of additive genetic effects for this stress tolerance index. A significant correlation among Hp, Hs, MP, GMP and STI showed the efficiency of these stress indices for improving plant height in plant breeding programme. In comparison to SCA effects, most of the crosses had significant high parent heterosis for Hp, Hs and all the stress indices. RGS003 with a significant positive GCA effect of Hs was considered as a suitable parent for improving this trait and most of the combinations of this genotype had significant negative SCA effects.

Resumen

Height growth for interior spruce (Piceaglauca (Moench) Voss and P. engelmannii Parry) after 3, 6, and 10 growing seasons was assessed in a progeny test of 174 wind-pollinated families at three test sites in north central British Columbia. Test sites had a major influence on the juvenile growth of interior spruce, reflecting differences in potential site productivity as well as the importance of good site preparation and subsequent brush control for spruce seedlings. Mean heights within and across sites differed among families. The 3- and 6-year family performances correlated with family performances at age 10. Family–site interaction was significant at the 1% probability level, but accounted for no more than a quarter of the family variance at the three assessment years. Performance of the top and bottom 25% of families was consistent across the three sites. The narrow-sense heritability estimates after the third, sixth, and tenth growing seasons were 0.52, 0.36, and 0.29, respectively. The corresponding family heritability estimates were 0.82, 0.73, and 0.67, respectively.

Resumen

Information on the nature and amount of genotype × environment (GE) interaction for economic traits and persistence is extremely rare in smooth bromegrass (Bromus inermis Leyss.), especially under drought stress. In this study, 25 half-sib (HS) families of smooth bromegrass were evaluated in the field during five consecutive years under normal and water deficit conditions. The effect of water deficit on dry forage yield was increased from the first year to the fifth, and manifested as a decline in persistence of HS families. Based on narrow-sense heritability estimates, additive gene action was found to be an effective factor in the control of yield components, whereas forage yield is controlled by both additive and non-additive gene actions. Considering the three parameters of stability of combining ability, mean performance and drought tolerance simultaneously, it was inferred that four parental genotypes were superior and stable with high values of general combining ability. This indicates that when developing synthetic varieties from these genotypes, both stability and plant productivity are transmitted to their progenies.

Resumen

A 3-year study on the incidence and severity of leaf rust caused by Melampsoraoccidentalis on hybrid poplars began in 1987 when inter- and intra-specific crosses were made with 20 Populustrichocarpa (T), 8 Populusmaximowiczii (M), and 3 Populustrichocarpa × Populusdeltoides (TD) parents. A total of 5100 seedlings from 67 families were initially surveyed for rust in 1988; however, this number declined to less than 3700 by 1990, and rust infection likely contributed to seedling mortality. There was significantly greater rust incidence and severity in T × T crosses than in T × M, M × TD, TD × M, or M × M crosses. For the 12 M × M crosses and the 6 three-way crosses (M × TD, TD × M), less than 1% of the seedlings had any rust in the 3 years. In the 20 T × M crosses, over 65% of the seedlings showed no rust and less than 1% showed heavy rust. For T × T seedlings from 29 crosses, less than 3% had no rust. Reciprocal crosses of P. trichocarpa from east or west of the Cascade Mountains in Washington showed that the female parent contributed more to rust susceptibility than the male parent. In regression analyses, P. trichocarpa midparent rust ratings were negatively correlated with family survival and positively correlated with the mean progeny rust rating. Narrow-sense family heritabilities were moderate to high for rust susceptibility (h2 = 0.43 in 1988, 0.53 in 1989, and 0.79 in 1990).

Resumen

Morphological productivity is difficult to define and describe. Nevertheless have several measures been proposed by scholars, in order to quantify this notion. This paper investigates ten common English prefixes with meanings related to degree or size. The aims of the study are (1) to review several measures of morphological productivity, (2) via a sample of corpus occurrences of ten prefixes, to calculate productivity figures using five different measures of productivity, and (3), perhaps most importantly, to discuss the differences and similarities of the five measures. The results suggest that while several of the measures are quite similar (e.g. type frequency and hapax legomena frequency), other measures are different (e.g. 'Productivity in the narrow sense'). While three of the measures could be said to provide information concerning past or 'factual' productivity, two of the measures seem instead to indicate an aspect of productivity that is referred to as 'potential' productivity.

Resumen

We develop a framework for establishing sample sizes in breeding plans, so that one is able to estimate narrow-sense heritability with smallest possible variance, for a given amount of effort. We call this an optimal genetic design. The framework allows one to compare the variances of estimators of narrow-sense heritability, when estimated from each one of the alternative plans under consideration, and does not require data simulation, but does require computer programming. We apply it to the study of a peanut (Arachis hypogaea) breading example, in order to determine the ideal number of plants to be selected at each generation. We also propose a methodology that allows one to estimate the additive genetic variance for the estimation of the narrow-sense heritability using MINQUE and REML, without an analysis of variance model. It requires that one can build the matrix of genetic variances and covariances among the subjects on which observations are taken. This methodology can be easily adapted to ANOVA-based methods, and we exemplify by using Henderson's Method III. We compare Henderson's Method III, MINQUE, and REML under the proposed methodology, with an emphasis on comparing these estimation methods with non-normally distributed data and unbalanced designs. A location-scale transformation of the beta density is proposed for simulation of non-normal data.

Resumen

Horizontal mapping, aerial photography, and current meter deployment have been used to identify a tidally induced mixing event about a promontory in the Strait of Georgia, British Columbia, Canada. Mixing plumes were observed to commence, downstream of Shingle Spit during ebb tides when the mean velocity for the water column reached a minimum of 12.7 cm.s⁻¹. Mixing plumes on ebb tides, were characterized by increased surface salinities as well as increased nitrate + nitrite and phosphate concentrations. Increases in concentrations of nitrate + nitrite of 2.6 μg at .1⁻¹ and phosphate of 0.45 μg at.1⁻¹ were observed in the euphotic zone associated with the mixing plumes. Nutrient additions were correlated to an increase in primary production of 13.8 mg C.m⁻³ in the mixed water as determined by the uptake of ¹⁴CO₃²⁻. Estimates of total volume of upwelling during the stratified months of June and July 1986 were performed allowing an estimation of the net flux of new nutrients into the euphotic zone during this period. The total increase in primary production due to mixing occurring downstream of Shingle Spit was determined experimentally to range between 910 and 2.2x10⁴ kg of "new production" compared to the Redfield stoichiometric estimate of from 1.4x10³ to 3.0x10⁴ kg of "new production" during June and July, 1986. Measurements of net flow in Lambert Channel allowed determination of the destination of the increases in primary production. It is suggested that utilization of increases in primary production caused increases in the zooplankton standing stock in the region south of Lambert Channel and Hornby Island. Gut contents of adult Qncorhynchus kisutch caught in the region contained zooplankton groups which were components of the increase of zooplankton standing stock. The presence of these zooplankton groups in the gut contents suggests utilization of the increases in zooplankton standing stock by predators further up the food chain.

ENGLISH ABSTRACT: In this thesis, the investigation into the optimization of low speed communication protocols for narrow band networks will be presented. The main focus will be on analysing commonly used low speed communication protocols and investigate an alternative to these protocols to provide an optimized low speed narrow band network that provides better performance at high and low channel utilization. A study of existing low speed communication networks within the field of water supply has been used to identify the most appropriate protocols to be included in the analysis. The analysis of each protocol discussed includes the development of a simulation and theoretical model, with parameters based on those obtained from implemented communication networks focusing on the parameters used within the Namib water supply scheme of NamWater in Namibia. Of the currently implemented contention protocols, the non-persistent Carrier Sense Multiple Access (CSMA) protocol is implemented the most. Current models used for modelling these protocols make use of various assumptions. These models have been expanded to provide a more accurate representation of the non-persistent CSMA model. The Round Robin Polling (RRP) protocol is another well known protocol used within the telemetry industry and has also been modelled as an alternative to the non-persistent CSMA model. The Adaptive Tree Walk (ATW) protocol has been identified as the limited contention protocol to be modelled as a possible alternative to the conventional methods used. A new model has been developed for modelling this protocol by making use of the same strategies and tools used in the modelling of the non-persistent CSMA and RRP protocols. The Simulation modelling has been developed by making use of DESMO-J, an Object Orientated Simulation API based in Java, developed by the Faculty of Informatics at the University of Hamburg. DESMO-J has been chosen as an alternative to the more traditional simulation languages due to its complete documentation, support structures, ease of use and flexibility. All theoretical models have been implemented in Matlab.
AFRIKAANSE OPSOMMING: In hierdie tesis sal die ondersoek na die optimering van laespoed protokolle vir kommunikasie oor nouband netwerke voorgelê word. Die hoof fokus is op die analise van algemene laespoed kommunikasie protokolle en die ondersoek van alternatiewe wat ’n meer optimale laespoed nouband netwerk sal lewer deur beter werkverigting by lae en hoë kanaalverkeer. ’n Studie van praktiese laespoed nouband netwerke in die veld van waterverspreiding word gebruik om die mees algemene protokolle te identifiseer wat in die analise ingesluit moet word. Die analise van die protokolle sluit in teoretiese en simulasie modelle, met parameters soos geidentifiseer uit die studie van ‘n praktiese netwerk, naamlik die Namib waterverspreidingskema van NamWater in Namibië. Die ’Non-persistent Carrier Sense Multiple Access’ en ’Round Robin Polling’ protokolle is geidentifiseer as dié wat meeste geimplementeer word. Die werkverigting van die protokolle is geanaliseer deur gebruik te maak van teoretiese en simulasie modeleringstegnieke. Huidige modelle van die CSMA protokol is gebaseer op sekere aannames. Hierdie aannames word aangepas en verbeter vir implementering van die teoretiese model. Die model word ook verder uitgebrei om beter resultate te lewer oor ’n groter parameterstel. Die ’Adaptive Tree Walk’ protokol is geidentifiseer as ’n moontlike optimale protokol en word gemodeleer en vergelyk teen die CSMA en RRP protokolle se werkverigting. Die simulasiemodelle is ontwikkel deur gebruik te maak van die DESMO-J sagteware, soos ontwikkel as ’n Java program-koppelvlak deur die Universiteit van Hamburg se Fakulteit van Informatika. DESMO-J is gekies as ’n alternatief vir die meer tradisionele simuleringstale omrede goeie dokumentasie, maklike gebruik en buigbaarheid. Alle teoretiese modelering is uitgevoer in Matlab.

Sammanfattning Titel: Vildsvinskedjan – En utvärderingsstudie av handeln av vildsvinskött i södra Sverige Kurs: Kandidatuppsats Civilekonomprogrammet, Controller 15 hp (2FE24E) Lärosäte: Ekonomihögskolan vid Linnéuniversitet Växjö Författare: Victoria Fagerlund Larsson, Anton Lindh och Max Börjesson Handledare: Elin Funck Examinator: Pia Nylinder Nyckelord: Logistikprocesser, processer, trånga sektioner, flaskhalsar, effektivitet, kvalitet, produktivitet, kartläggning, utvärdering och Supply Chain Management. Bakgrund: Det finns problem med handeln av vildsvinskött, där det idag inte är mer än 15% av köttet som når den legala marknaden. Detta beror på de hinder och flaskhalsar som existerar i kedjan som i dagsläget hindrar en effektiv kedja. Den resterande delen av köttet förbrukas antingen av jägarna själva eller för populationskontroll och skadedjursskjutning då vildsvin kan orsaka stora skador på bönders verksamhet. Detta leder till att det sker ett stort svinn av helt ätbart kött som hade kunnat säljas på en marknad. Syfte: Syftet med uppsatsen är att kartlägga logistikkedjan för vildsvinskött i södra Sverige. Genom kartläggningen identifieras svårigheter som finns inom logistikkedjan idag. Utifrån relevant teori ges förslag på potentiella förbättringar. Genom att överkomma svårigheterna möjliggörs en mer effektiv logistikkedja, med mer vildsvinskött på marknaden och ökad lönsamhet för de olika aktörerna som verkar inom kedjan. Metod: I uppsatsen har en processutvärdering använts för att kunna få en överblick över processerna och vad som behöver förändras. Den empiriska materialinsamlingen gjordes genom semistrukturerade intervjuer. Slutsats: I uppsatsen har handeln av vildsvinskött kartlagts. Hinder har identifierats och förslag presenterats. En av de tydligaste slutsatserna har visat sig vara stora fluktuationerna i både utbud och efterfrågan vilket innebär att det är svårt att göra prognoser, vilket vi ändå föreslår att man gör. Digitaliseras prognoserna skulle informationsutbytet bli betydligt bättre då butiker och anläggningar skulle kunna dela prognoser om utbud och efterfrågan med varandra. Det hade lett till ett bättre in- och utflöde på marknaden vilket slutligen resulterat i en bättre fungerande handel av vildsvinskött.
Abstract Title: The wild boar chain- An evaluation study of the market of wild boar meat in southern Sweden Course: Bachelor Thesis in Business Administration, Controller 15 hp (2FE24E) Institution: School of Business and Economics at Linnaeus University in Växjö Authors: Victoria Fagerlund Larsson, Anton Lindh and Max Börjesson Tutor: Elin Funck Examiner: Pia Nylinder Keywords: Logistics processes, processes, narrow section, bottleneck, efficiency, improvement, quality, productivity, process mapping and evaluation. Background: No more than 15% of wild boar meat reaches the market because of the issues surrounding the market. It exists of obstacles and bottlenecks in the chain that hinder an effective market. The rest of the 85% of wild boar meat that does not reach the market is consumed by hunters and wasted because of population control and pest control because wild boars cause damage for farmers. This leads to partially wasted meat which could have been sold on the market for profits. Purpose: The purpose of this study is to map the process of the logistic chain for wild boar meat in southern Sweden. The difficulties that exist today in the logistic chain will be identified through process mapping. We also give suggestions for potential improvements, supported by relevant theory. Overcoming these difficulties will enable a more efficient logistic chain, with more wild boar meat on the market and increased profitability for the different actors that operate within the chain. Method: This essay uses a process evaluation study to be able to get an overview of the processes and what needs to change. The empirical material was collected through semi-structured interviews. Conclusion: The market for wild boar meat in Sweden has been identified through process mapping. Problems have been visualized and potential solutions have been presented. This paper has showed large fluctuations in both demand and supply. That means that it is difficult to make forecasts. We suggest forecasts as a tool for predicting the fluctuations. The sharing of information between the different parties will be considerably better if stores and the plants that handle wild boar meat in Sweden digitalize the forecasts. That would increase the inflow and the outflow to the market. This would result in a better logistic chain for wild boar meat.

Resumen

In most breeding programmes breeders use phenotypic data obtained in breeding trials to rank the performance of the parents or progeny on pre-selected performance criteria. Through this ranking the best candidates are identified and selected for breeding or production purposes. Best Linear Unbiased Prediction (BLUP), is an efficient selection method to use, combining information into a single index. Unbalanced or messy data is frequently found in tree breeding trial data. Trial individuals are related and a degree of correlation is expected between individuals over sites, which can lead to collinearity in the data which may lead to instability in certain selection models. A high degree of collinearity may cause problems and adversely affect the prediction of the breeding values in a BLUP selection index. Simulation studies have highlighted that instability is a concern and needs to be investigated in experimental data. The occurrence of instability, relating to collinearity, in BLUP of tree breeding data and possible methods to deal with it were investigated in this study. Case study data from 39 forestry breeding trials (three generations) of Eucalyptus grandis and 20 trials of Pinus patula (two generations) were used. A series of BLUP predictions (rankings) using three selection traits and 10 economic weighting sets were made. Backward and forward prediction models with three different matrix inversion techniques (singular value decomposition, Gaussian elimination - partial and full pivoting) and an adapted ridge regression technique were used in calculating BLUP indices. A Delphi and Clipper version of the same BLUP programme which run with different computational numerical precision were used and compared. Predicted breeding values (forward prediction) were determined in the F1 and F2 E. grandis trials and F1 P. patula trials and realised breeding performance (backward prediction) was determined in the F2 and F3 E. grandis trials and F2 P. patula trials. The accuracy (correlation between the predicted breeding values and realised breeding performance) was estimated in order to assess the efficiency of the predictions and evaluate the different matrix inversion methods. The magnitude of the accuracy (correlations) was found to mostly be of acceptable magnitude when compared to the heritability of the compound weighted trait in the F1F2 E. grandis scenarios. Realised genetic gains were also calculated for each method used. Instability was observed in both E. grandis and P. patula breeding data in the study, and this may cause a significant loss in realised genetic gains. Instability can be identified by examining the matrix calculated from the product of the phenotypic covariance matrix with its inverse, for deviations from the expected identity pattern. Results of this study indicate that it may not always be optimal to use a higher numerical precision programme when there is collinearity in the data and instability in the matrix calculations. In some cases, where there is a large amount of collinearity, the use of a higher precision programme for BLUP calculations can significantly increase or decrease the accuracy of the rankings. The different matrix inversion techniques particularly SVD and adapted ridge regression did not perform much better than the full pivoting technique. The study found that it is beneficial to use the full pivoting Gaussian elimination matrix inversion technique in preference to the partial pivoting Gaussian elimination matrix inversion technique for both high and lower numerical precision programmes.

Resumen

Genetic variances and heritabilities in a cloned Eucalyptus grandis breeding population of families derived from open pollinated selections were estimated and the results are presented. The genetic variance was partitioned into additive and non-additive genetic variance components that allowed the estimation of broad and narrow sense heritabilities. Predicted gains for breeding and production population options are discussed. The magnitude of the coefficient of relationship between sibs was shown to have a considerable impact on the estimate of variance components and the importance of understanding the level of relatedness in the population is highlighted. Growth traits (volume, diameter at breast height/DBH, height), stem from and disease tolerance were assessed at 38 and 66 months in each of the three separate trials established as sub-populations of the breeding population. The additive genetic variance was the largest proportion of genetic variance for the growth traits (84% for volume, 94% for height and 74% for DBH), whereas the proportion of non-additive genetic variance was notably higher for stem form and disease tolerance (37% and 46% respectively). The growth traits and stem from are, economically, the most important traits and a breeding strategy that exploits the additive genetic variation by selection to increase the frequency of the alleles causing the desirable genotypes is appropriate. The higher proportion of non-additive genetic variance for disease does, however, suggest higher gains (compared with the afore-mentioned strategy of selection for general combining ability) will be achieved by exploiting the non-additive variance by for example, selection for specific combining ability, using inbred lines, clones. The composition of the genetic variance was investigated separately in the F1 and F2 families to obtain an indication of whether or not there was a change in proportion of non-additive and additive genetic variance over the two generations. A notably larger proportion of non-additive variance was found for the growth traits and stem form among the F2 families. This is probably due to the reduction in additive variance through selection for these traits in the previous generations. No selection for disease took place in earlier generations and the proportion of non-additive genetic variance for this trait remains approximately the same over both generations. These results may indicate that with advanced generations of breeding in this population, that gains achieved through selection for additive variance will decline compared with that achieved in previous generations. A strategy for future generations that exploits non-additive variance may be appropriate. A high proportion of error variance was estimated and in situations such as these, cloning is particularly beneficial as is shown by the high clone mean heritabilities estimated in these trials. High mortality, resulting in fewer ramets per clone, erodes the benefit of cloning in these trials. The predicted gains showed the benefit of the cloned breeding population both in terms of breeding population gains and production population gains. Reducing the breeding cycle by bulking up clones faster will also increase gains per year. High gains in the production population were predicted, particularly for the selection of tested clones for deployment, which can be done at the same time as selections are made for the next generation. The benefit of the cloned population was therefore shown to be twofold, namely increasing the accuracy of within family selection and increasing the gains in the rapid deployment of tested clones and therefore facilitating the faster realization of predicted gain in the plantation.

Resumen

The purpose of the present study is to further examine the relationship between personality traits and Psychological Sense of Community (PSC). It attempts to confirm previous research findings that indicate a significant relationship between the Big Five traits and PSC. In addition, it seeks to determine whether selected narrow personality traits are significantly related to PSC and whether those traits add incremental validity to the Big Five personality traits in predicting PSC. This study is a secondary analysis of data collected by Resource Associates, Inc between 2003-2005. Participants (N=1468) were students at a large, southeastern university. Results confirmed a positive relationship between PSC and four of the Big Five traits. Correlational analysis further indicated that all four selected narrow personality traits are positively related to PSC. A hierarchical multiple regression analysis revealed that the narrow traits of Career-Decidedness, Optimism, Work Drive, and Sense of Identity, while significant, accounted for a modest proportion of the variance in the prediction of PSC. Implications, limitations, and directions for future research are discussed.

Resumen

An employed individual will spend between a quarter and a third of his or her waking life at the workplace. An estimated 40% of those in South Africa who are employed full-time work in offices. With the amount of time spend in buildings, the physical conditions in the workplace are important determinants of satisfaction, comfort, well-being, and effectiveness and can even play a role in mental health. The physical environment in offices should therefore be carefully planned, designed, and managed. This qualitative study, sought to develop an inter-cultural office design framework for South Africa combining Eastern and Western design principles. Specifically, it sought to obtain a better insight into design principles which can enhance the well-being of office workers; inter-cultural, gender neutral and age neutral design principles which can be applied in a South African context. To be able to answer these questions an intensive literature review was undertaken investigating both the Eastern design principles as expressed in feng shui and Western design principles as expressed in Environmental Social Science. The design principles of these two traditions were compared and all aspects where the two traditions did not support each other were included in the in-depth interviews. Twenty-five in-depth interviews were conducted By relying on various design cultures (e.g. Eastern and Western) an environment can be created which are pleasing and can enhance the well-being of the users. Underlying design principles are universal, but the symbolic expression thereof can differ from culture to culture. One of the conclusions from this study is that three quarters of design principles are v universal. There is no one size fits all solution and compromise is necessary from all involved. The compromise applies to the roughly a quarter of design aspects where subgroup differences have been detected. Any design should take individual and group difference into account. The only way to do this is to get proper input from all stakeholders at all stages of the design. It is critically important that the input starts before the design process commences. There are many design principles which can be implemented to improve the quality of work life of office workers in the South African context. Design can for example play a very important role in encouraging and facilitating formal and informal interaction in the workplace – bridging the gap between heterogeneous groups. Without forcing relationships, design can assist in naturally integrating heterogeneous groups. The physical environment must support the image and identity which needs to be communicated, facilitate communication and enable task accomplishment. Most of all it must become a place with which employees can identify and where they can develop a sense of place. From this study it can be concluded that not only form follows function but also that aesthetics follow function – a principle that design should be based on the primary purpose of the building, the workspace based on the needs of the stakeholders and from this starting point aesthetics will flow.

Resumen

The chapter examines the various propositional and predicate many-valued logics that were studied prior to the emergence of the concept of a fuzzy set in the mid-1960s, which led to the genesis of fuzzy logic in broad and narrow senses. Early ideas regarding formal systems of fuzzy logic allowed for deduction from partially true premises to partially true consequences, as suggested first by Goguen in the 1960s and further developed by Pavelka in the 1970s, and these ideas were developed from the 1990s onward. The systematic development of fuzzy logics based on t-norms and their residua, pursued under the leadership of Hájek in the 1990s, is discussed in some detail. An overview is presented of fuzzy logics that are not truth-functional, such as probabilistic, possibilistic and modal fuzzy logic. The chapter concludes by reviewing relevant additional issues, such as issues of computational complexity for fuzzy logic or higher-order fuzzy logics.

Resumen

Narrow mental content, if there is such a thing, is content that is entirely determined by the goings-on inside the head of the thinker. A central topic in the philosophy of mind since the mid-1970s has been whether there is a kind of mental content that is narrow in this sense. It is widely conceded, thanks to famous thought experiments by Hilary Putnam and Tyler Burge, that there is a kind of mental content that is not narrow. But it is often maintained that there is also a kind of mental content that is narrow, and that such content can play various key explanatory roles relating, inter alia, to epistemology and the explanation of action. This book argues that this is a forlorn hope. It carefully distinguishes a variety of conceptions of narrow content and a variety of explanatory roles that might be assigned to narrow content. It then argues that, once we pay sufficient attention to the details, there is no promising theory of narrow content in the offing.

Resumen

In Chapter 1 we clarify and make precise a number of the key notions that will be used in the rest of the book—most notably those of content and narrowness. There is also a substantial critical discussion of the thesis that ‘character’, in something like David Kaplan’s sense, is narrow, instead of content. This discussion is the chapter’s main original contribution.

Resumen

The chapter begins by introducing the important and useful distinction between the research agendas of fuzzy logic in the narrow and the broad senses. The chapter deals with the latter agenda, whose ultimate goal is to employ intuitive fuzzy set theory for emulating commonsense human reasoning in natural language and other unique capabilities of human beings. Restricting to standard fuzzy sets, whose membership degrees are real numbers in the unit interval [0,1], the chapter describes how this broad agenda has become increasingly specific via the gradual development of standard fuzzy set theory and the associated fuzzy logic. An overview of currently recognized nonstandard fuzzy sets, which open various new directions in fuzzy logic, is presented in the last section of this chapter.

Resumen

This article explores the relationship between temporality, aesthetics, and sexuality in Pier Paolo Pasolini’s Petrolio and Elsa Morante’s Aracoeli. Both novels mobilize a form of temporality that resists a sense of linear and teleological development and that instead appears contorted, inverted, suspended and thereby allows for the articulation of queer desires and pleasures that cannot be inscribed in normative logics of completion, progression, or productivity.

Resumen

AbstractOne central pillar in the development of urban science which is key to the development of simulation of models of urban structure is spatial econometrics. In this chapter, we outline the way in which ideas pertaining to accessibility which we define conventionally, as in transport economics, as the relative nearness and size of locations to one another, can be embedded in a wider econometric framework. We are thus able to explore how GDP (gross domestic product) of different locations is influenced by different spatial investments. To illustrate this, we first outline the intellectual context, followed by a review of the most relevant econometric models. We examine the data required for such models and look at various quantifications in terms of elasticities of business productivity with respect to transport accessibility, using ordinary least squares, time-series fixed effects, and a range of dynamic panel-data models which narrow down the valid range of estimates. We then show how the model is applied to Guangdong province (with its connections to Hong Kong and Macau), which is one of the three major mega-city regions and a leading adopter of new technologies in China.

Resumen

AbstractGlobal climate change poses a great threat to poultry production. Greenhouse gases (GHGs) are released through both natural and anthropogenic sources into the atmosphere. Though poultry production contributes little to the release of GHGs, the subsector has been shown to be greatly affected by climate change and global warming. Poultry production as a major subsector of agriculture has provided the teeming population with a supply of needed animal protein in terms of meat and egg production all over the world. It is yet a major global employer of labor. Though it occupies a vantage position in meeting human needs, it is being threatened by climate change, especially in Africa where necessary structure to tackle the menace is nonexistent. Broiler chickens that are reared mainly for chicken meat cannot tolerate the high ambient temperature that prevails mostly in the tropical environment. Chickens are homeotherms that homeostatically regulate core body temperature within a narrow range. Elevated ambient temperature above thermal comfort zone, such as envisaged in climate change scenarios, will trigger series of neuroendocrine modulations that are detrimental to the welfare and productivity in broiler chickens. Such birds are said to be undergoing heat stress (HS). Negative effects of HS include reduced feed consumption, growth rate, feed digestion and efficiency, immunity, welfare, and survivability. Various adaptive measures that could be harnessed by broiler farmers, ranging from housing, feeding, watering, stocking, breeding for thermo-tolerant strains, thermal conditioning, use of phytochemicals, and much more, are reviewed upon in this chapter.

Resumen

Although workforce productivity is widely used today, production is quickly moving toward product and process development with customers. Creative customers would like to get more and more involved in product development and furthermore, they would like to get satisfaction not only from the final product but from the processes as well. So we have to introduce a new measure for productivity, which focuses more on how much satisfaction a customer obtains from production. So the new definition of productivity in this sense will be: Customer productivity = Amount of satisfaction / Customer’s psychological time and money (physical and virtual involvement in production) This is different from the current customer satisfaction. Current one is focused on how much satisfaction a customer will have for a final product. This is a definition from the standpoint of the producer. The new definition is from the standpoint of the customer. This paper points out that if we introduce Mahalanobis Taguchi System, such a measure can be established and we can introduce a new metric for measuring customer’s satisfaction for the new type of prosumer system or co-production.

Resumen

This paper presents an adaptive add-on compensator to handle a single narrow-band disturbance with unknown frequency in hard disk drives (HDDs). A disturbance observer (DOB) loop with a narrow band pass Q filter is built around the baseline servo controller to reject the narrow-band disturbance. The frequency parameter of the Q filter is directly adapted to the optimal value in the sense of minimizing the track following track mis-registration (TMR). The performance of the proposed compensator is demonstrated by simulation on an open-source realistic hard disk drive system.

Resumen

Since the 19th century, the position of women in the context of higher education has undergone multiple changes, although their incorporation has not been a simple or homogeneous task. Currently, women face new consequential challenges of a globalized world and the notion of market education that characterizes institutions nowadays. One of the great challenges is related to the under-representation of women in senior research positions (Aiston and Fo, 2020). In this context, new standards have been established to measure the productivity, quality, and effectiveness of teachers, specifically scientific productivity has been internalized as an indicator of professional progress, the type of publication, its impact, and the citation rates today. They have special relevance, where many times achieving high scientific productivity is very complex for academics who do not access the teaching staff early (Webber and Rogers, 2018). Furthermore, it is very difficult for academic women to maintain high levels of productivity constantly both at work and home (Lipton, 2020). In this sense, the principles that encourage academic productivity increase competition among teachers and reinforce gender inequalitiestogether with a valuation of male professional life (Martínez, 2017). Indeed, the participation of women in sending articles is much lower than their male counterparts (Lerback and Hanson, 2017). Therefore, the present study aims to visualize the participation of Chilean academics in current productivity indices, based on the description of secondary data obtained from the DataCiencia and Scival platforms. The sample consists of 427 people, of which 17.3% were women, with an average of 10 publications for the year 2019. To achieve the objectives, the following strategy was developed: 1) describe and interpret the secondary data obtained during the year 2019 on each of the platforms. 2) Compare the data obtained to national averages and type of institution and gender. Based on the analyzes, the implications of female participation in the number of women observed at the national level and their position in international indicators and new lines of research are discussed.

Resumen

Information and communication technologies are offering us needed infrastructure for connecting individuals from different cultures, places and work environments to learn and work together. In this paper we created a literature review on subject of virtual teams. We were answering the question “What are the most common problems when building relationships in remote workspace and how we can eliminate them?”. First responsible party in creating a good work atmosphere in between employees is management. Management and leaders of work teams is the first source from where employees are getting the sense of organizational culture. This task was much easier before Covid-19 epidemy, because first impressions and relationships were created with physical contact. In 2020 majority of organizations reconstructed their work dynamics and started with remote work. Team leaders had to adapt new work habits and way of carrying out work loads remotely. With that they lost physical contact, relationship between employees started to deteriorate, workers started to loose sense for the work load and time spent for it, distractions at home did not add to the employee productivity. With this literature preview we found out that leaders are finding biggest problems in weakened communication, bad management, inability to overview employee productivity, and cultural and language differences.

This study combines three rounds of surveys with remote sensing to measure long-term impacts of a randomized irrigation program in the Dominican Republic. Specifically, Landsat 7 and Landsat 8 satellite images are used to measure the causal effects of the program on agricultural productivity, measured through vegetation indices (NDVI and OSAVI). To this end, 377 plots were analyzed (129 treated and 248 controls) for the period from 2011 to 2019. Following a Differencein-Differences (DD) and Event study methodology, the results confirmed that program beneficiaries have higher vegetation indices, and therefore experienced a higher productivity throughout the post-treatment period. Also, there is some evidence of spillover effects to neighboring farmers. Furthermore, the Event Study model shows that productivity impacts are obtained in the third year after the adoption takes place. These findings suggest that adoption of irrigation technologies can be a long and complex process that requires time to generate productivity impacts. In a more general sense, this study reveals the great potential that exists in combining field data with remote sensing information to assess long-term impacts of agricultural programs on agricultural productivity.

Resumen

Ours is an age of pervasive political turbulence, and the scale of the challenge requires new thinking on politics as well as public ethics for our world. In Western countries, the specter of Islamophobia, alt-right populism, along with racialized violence has shaken public confidence in long-secure assumptions rooted in democracy, diversity, and citizenship. The tragic denouement of so many of the Arab uprisings together with the ascendance of apocalyptic extremists like Daesh and Boko Haram have caused an even greater sense of alarm in large parts of the Muslim-majority world. It is against this backdrop that M.A. Muqtedar Khan has written a book of breathtaking range and ethical beauty. The author explores the history and sociology of the Muslim world, both classic and contemporary. He does so, however, not merely to chronicle the phases of its development, but to explore just why the message of compassion, mercy, and ethical beauty so prominent in the Quran and Sunna of the Prophet came over time to be displaced by a narrow legalism that emphasized jurisprudence, punishment, and social control. In the modern era, Western Orientalists and Islamists alike have pushed the juridification and interpretive reification of Islamic ethical traditions even further. Each group has asserted that the essence of Islam lies in jurisprudence (fiqh), and both have tended to imagine this legal heritage on the model of Western positive law, according to which law is authorized, codified, and enforced by a leviathan state. “Reification of Shariah and equating of Islam and Shariah has a rather emaciating effect on Islam,” Khan rightly argues. It leads its proponents to overlook “the depth and heights of Islamic faith, mysticism, philosophy or even emotions such as divine love (Muhabba)” (13). As the sociologist of Islamic law, Sami Zubaida, has similarly observed, in all these developments one sees evidence, not of a traditionalist reassertion of Muslim values, but a “triumph of Western models” of religion and state (Zubaida 2003:135). To counteract these impoverishing trends, Khan presents a far-reaching analysis that “seeks to move away from the now failed vision of Islamic states without demanding radical secularization” (2). He does so by positioning himself squarely within the ethical and mystical legacy of the Qur’an and traditions of the Prophet. As the book’s title makes clear, the key to this effort of religious recovery is “the cosmology of Ihsan and the worldview of Al-Tasawwuf, the science of Islamic mysticism” (1-2). For Islamist activists whose models of Islam have more to do with contemporary identity politics than a deep reading of Islamic traditions, Khan’s foregrounding of Ihsan may seem unfamiliar or baffling. But one of the many achievements of this book is the skill with which it plumbs the depth of scripture, classical commentaries, and tasawwuf practices to recover and confirm the ethic that lies at their heart. “The Quran promises that God is with those who do beautiful things,” the author reminds us (Khan 2019:1). The concept of Ihsan appears 191 times in 175 verses in the Quran (110). The concept is given its richest elaboration, Khan explains, in the famous hadith of the Angel Gabriel. This tradition recounts that when Gabriel appeared before the Prophet he asked, “What is Ihsan?” Both Gabriel’s question and the Prophet’s response make clear that Ihsan is an ideal at the center of the Qur’an and Sunna of the Prophet, and that it enjoins “perfection, goodness, to better, to do beautiful things and to do righteous deeds” (3). It is this cosmological ethic that Khan argues must be restored and implemented “to develop a political philosophy … that emphasizes love over law” (2). In its expansive exploration of Islamic ethics and civilization, Khan’s Islam and Good Governance will remind some readers of the late Shahab Ahmed’s remarkable book, What is Islam? The Importance of Being Islamic (Ahmed 2016). Both are works of impressive range and spiritual depth. But whereas Ahmed stood in the humanities wing of Islamic studies, Khan is an intellectual polymath who moves easily across the Islamic sciences, social theory, and comparative politics. He brings the full weight of his effort to conclusion with policy recommendations for how “to combine Sufism with political theory” (6), and to do so in a way that recommends specific “Islamic principles that encourage good governance, and politics in pursuit of goodness” (8).
