Movement Behaviour of Alien Largemouth Bass Micropterus salmoides in the Estuarine Headwater Region of the Kowie River, South Africa

The movement behaviour of largemouth bass Micropterus salmoides in the estuarine headwater region of the Kowie River, South Africa, was investigated using passive acoustic telemetry. Ten adult fish were tagged and released in four discrete pools below a weir that precluded possible upriver migration. Their residency and movement patterns were monitored using 27 moored acoustic receivers spanning both riverine and estuarine habitats between January and November 2013. Small-scale movements ranging from 50 to 400 m occurred between pools in the headwater region, where tagged fish remained resident (did not leave their tagging pool) during the warmer (summer) months. The onset of autumn and winter correlated with declining water temperatures and half of the tagged largemouth bass made downstream excursions into the slightly warmer upper reaches of the estuary. The penetration of these alien piscivores into estuarine headwaters potentially provide additional predator pressure on the juveniles of migratory estuary-associated native marine fish species, which utilise these areas as nurseries. The presence of the alien fish in South African estuarine headwaters may impair the migration of juvenile fishes between the estuarine and freshwater environments.
Development of soy-fortified biscuits and shelf-life studies

Control and soy biscuits prepared with standardized recipe were subjected to shelf life studies. Biscuits were packed in two different types of packaging materials viz., polypropylene and laminate of cellophane and butter paper and stored under ambient conditions of average temperature, at 29.5°C and RH. 73.5%. During storage, moisture content, peroxide value and free fatty acid contents of biscuits increased whereas hardness, crispness and overall sensory acceptability scores of biscuits decreased gradually. There was a slight non-significant increase in non-enzymatic browning of biscuits. These changes were more pronounced in biscuits packed in laminated packaging than in polyprophylene film irrespective of levels of soy fortification. Thus, polypropylene proved to be a better packaging material for biscuits than the laminated one and biscuits packed in it could be stored for 45 days under ambient conditions whereas. in laminated packaging, the shelf-life of biscuits was 30 days. The keeping quality of biscuits could be increased further by storing them under low relative humidity conditions.
Molecular Evolution of Visual System Genes in Fishes

For many species, vision contributes to a number of fitness-related tasks, including mating and the detection of prey and predators. Selection on the visual system should therefore be strong, especially when ecological or genomic changes open new avenues for evolutionary changes. Visual system proteins are thus attractive systems for molecular evolutionary analyses. This thesis presents a collection of evolutionary studies on two gene families, opsins and crystallins. Opsin proteins determine the wavelengths of light detected by the retina, while crystallin proteins contribute to lens transparency and refractory power. My studies focus on teleost fishes, because teleost visual ecology is exceptionally diverse and because gene duplication is common in this group. In Chapter One, I outline the relevance of protein variation to organismal evolution and describe the analytical methods employed throughout this thesis. Chapter Two considers the long-wavelength sensitive (LWS) opsins of the guppy (Poecilia reticulata). The guppy is shown to possess multiple LWS opsins that have accumulated differences at functionally important amino acid sites since duplicating. Chapter Three focuses on the guppy’s main predator, the pike cichlid Crenicichla frenata, which is shown to have a greater capacity for short-wavelength vision than previously believed. However, this cichlid possesses three fewer opsins than closely-related African cichlids, a difference partly due to duplication of a green-sensitive (RH2) opsin in African cichlids. In Chapter Four, this RH2 duplication event is studied in greater depth; variation in selective constraint is documented following gene duplication and between species from different lakes. Some of the analytical methods employed in Chapter Four were newly developed, as detailed in Chapter Five, where a test for functional divergence among clades is evaluated and then improved upon through the presentation of a new null model that better accommodates among-site variation in selection. In Chapter Six, phylogenetic relationships within the βγ lens crystallin superfamily are clarified, and the functionally distinct γN family is shown to have evolved conservatively compared to other crystallin families. The thesis concludes with suggestions for future directions for evolutionary research on opsins and crystallins, and summarizes recent work that has built on these studies.

Produção e valor nutritivo da parte aérea da mandioca, maniçoba e pornunça

This work aimed to evaluate the growth, productivity and the chemical composition of cassava (Manihot esculenta Crantz.), manicoba (Manihot glaziowii Mull.) and pornunca (a natural hybrid). The species were established in plots with row spacing of 3 m and stem cutting of 3 m, without fertilization or soil correction. A completely randomized design, as a 3 x 2 factorial arrangement (three species and two pruning systems), with three replicates was used. Pruning systems consisted of pruning 1 – cut of shoot area after 12 months after seeding and pruning 2: cut of shoot area at 12 months after previous standardization cut at nine months old. Significant differences (P 0.05) on the contents of neutral detergent fiber and acid detergent fiber and in vitro dry matter digestibility was observed. The levels of K and Mg did not differ (P>0.05) among treatments. Pornunca is outstanding due to the great productive potential and, therefore, can be used as a forage option for new studies.
THE IMPORTANCE OF STRENGTHENING EMPLOYEE PERFORMANCE THROUGH LEADERSHIP AND ENGAGEMENT, WITH WORK MOTIVATION AS AN INTERMEDIARY

Acoustic Absorbers and Diffusers, Theory, design and application

Absorbers and diffusers are two of the main design tools for altering the acoustic conditions of rooms, semi-enclosed spaces and the outdoor environment. Their correct use is important for delivering high quality acoustics. Unique and authoritative, this book decribes how to effectively measure, model, design and apply diffusers and absorbers. It is a resource for new and experienced acousticians, seeking an understanding of the evolution, characteristics and application of modern diffusers. Absorption is a more established technology and so the book blends traditional designs with modern developments. The book covers practical and theoretical aspects of absorbers and diffusers and is well illustrated with examples of installations and case studies. This new edition brings Acoustic Absorbers and Diffusers up-to-date with current research, practice and standards. New developments in measurement, materials, theory and practice since the first edition (published in 2004) are included. The sections on absorbers are extended to include more about noise control.
Evaluation of toxicological and molluscicidal activities of lactiferous plants against Biomphalaria glabrata (Say, 1818)

The intermediate hosts of schistosomiasis, namely the Biomphalaria snails, are essential to complete the Schistosoma mansoni cycle, and, therefore, synthetic molluscicides have been used to control this parasite. It is known, however, that synthetic molluscicides cause a major environmental impact. This study aimed to evaluate the molluscicidal activity of latex obtained from lactescent plants and determine their potential toxicity

Skilled Immigrants : Economic Contribution and Policy Implications

Firms compete globally to attract skilled workers – particularly in the fields of science and technology – and many countries have adopted immigration policies or programs favoring skilled foreign labor. Proponents of such policies argue that skills are scarce and, as a result, employers have difficulty finding qualified workers using domestic supply alone, which limits innovation and growth that would benefit large swaths of the economy. Opponents argue that no domestic skill shortage exists, and that employers simply want to hire cheap foreign labor that will undermine the wages and employment opportunities of native-born workers.
Reproductive Biology of Terapon Jarbua from the Estuary of Tamshui River

The larval anchovy fishery is one of the most important coastal fisheriesin Taiwan.The species caught mainly belong to the Family Engraulidae.Inthis paper,the factual distribution conditions of larval anchovy from thecoastal waters of Fang-Liao by means of hydroacoustic survey was studied.Serial observations on temperature and salinity were simultaneously recorded.The results are as follow:(1)The species caught was mainly composed of Engraulis japonica andpartly Stolephorus zollingeri and Stolephorus heterolobus.The optimal ranges oftemperature and salinity for Stolephorus were wider than those for Engraulisjaponica,while the optimal osmotic pressure ranges of the above two generawere 25.75-25.9 and 25.58-25.76atm,respectively. (2)Several larval anchovy schools may form a unique fish shoal alongtheir optimal osmotic pressure regions.The margin of fish shoal wasbordered by the flow axis of river discharge with low osmotic pressure andthat of offshore current with high osmotic pressure. (3)The composition of daily catch fluctuated with sea surface temperature(SST)and so did the composition of annual catch.When the southernoscillation index was strongly negative(i.e.E1-Nino)and the SST in winterwas anomalously warm,the major composition of caught species belonged toStolephorus.On the other hand,when the environmental condition wasresversal,the main catch became Engraulis japonica.

E2F7 regulates transcription and maturation of multiple microRNAs to restrain cell proliferation

E2F transcription factors (E2F1-8) are known to coordinately regulate the expression of a plethora of target genes, including those coding for microRNAs (miRNAs), to control cell cycle progression. Recent work has described the atypical E2F factor E2F7 as a transcriptional repressor of cell cycle-related protein-coding genes. However, the contribution of E2F7 to miRNA gene expression during the cell cycle has not been defined. We have performed a genome-wide RNA sequencing analysis to identify E2F7-regulated miRNAs and show that E2F7 plays as a major role in the negative regulation of a set of miRNAs that promote cellular proliferation. We provide mechanistic evidence for an interplay between E2F7 and the canonical E2F factors E2F1-3 in the regulation of multiple miRNAs. We show that miR-25, -26a, -27b, -92a and -7 expression is controlled at the transcriptional level by the antagonistic activity of E2F7 and E2F1-3. By contrast, let-7 miRNA expression is controlled indirectly through a novel E2F/c-MYC/LIN28B axis, whereby E2F7 and E2F1-3 modulate c-MYC and LIN28B levels to impact let-7 miRNA processing and maturation. Taken together, our data uncover a new regulatory network involving transcriptional and post-transcriptional mechanisms controlled by E2F7 to restrain cell cycle progression through repression of proliferation-promoting miRNAs.
A Study on Correlation of Emotional Intelligence to Leadership Styles of Nursing Mangers and Nurses’ Organizational Commitment in Hospitals of Kerman, Iran

In this descriptive-correlational study, nursing managers (supervisors) were selected, through the census method to complete emotional intelligence questionnaire. Then, according to Cochran formula, 300 nurses working under each supervisor were selected through categorical sampling method. Then they filled out organizational commitment questionnaire and leadership. The collected data were analyzed via inferential and descriptive statistics. The results showed that there was a significant relationship between emotional intelligence and leadership style of supervisors, and also between the leadership style and nurse’s organizational commitment. the results of this research and similar ones indicate the importance of the emotional intelligence role as an educable and learnable skill in workplaces and routine life. So, it is recommended that organizations, managers and staffs with more emotional intelligence are employed (particularly, attention to individual’s emotional intelligence in selection time) and also certain ways should be developed to increase emotional intelligence of managers and its current employees.
The Effects of Background Noise and Personal MP3 Player Volume on the Audibility to Bystanders

Purpose: To determine whether overhearing someone’s iPod is a valid way to tell whether the user was listening at hazardous listening levels. Method: An iPod Touch with standard earbuds was placed on a KEMAR mannequin in a sound booth. The output was recorded and measured from 28 inches away to simulate a bystander. Recordings of five songs at nine iPod volume levels were mixed with seven background noise conditions: quiet, pink noise (45, 60, and 75 dBA) and real-world noise (45 dBA speech babble; 60 dBA restaurant; and 75 dBA airplane). Participants were seated in the center of an eight-speaker array. The song was played at 0-degrees azimuth with the background noise presented from seven speakers (45, 90, 135, 180, 225, 270, and 315 degrees azimuth). Participants, 50 young, normal-hearing adults, indicated if they heard the music during each trial. Results: Participants were likely to overhear someone’s iPod in quiet; however, the probability that the song was at a hazardous listening level was low. As background noise levels increased, participants’ ability to overhear iPods decreased. Positive predictive value increased as real-world noise increased; however, the pink background noise did not maintain this trend. Conclusion: Overhearing someone’s iPod does not necessarily indicate they are listening at a hazardous level, and not overhearing someone’s iPod does not necessarily indicate they are listening at a safe volume level. Thus, being able to overhear music emanating from someone’s earphones is not a good indicator that iPod user is damaging his or her hearing.
Estimating the External Returns to Education: Evidence from China

Good understanding on the human capital externalities is important for both policy makers and social science researchers. Economists have speculated for at least a century that the social returns to education may exceed the private returns. In this paper, using the longitudinal data from China Health and Nutrition Survey (CHNS), we examine how individual wage changes associated with the share of college graduates in the same province across years for a person who has never moved by implementing individual fixed effects estimates. The individual fixed effect model shows that the external returns to education in China appear to be negative and on the order of -2%, which might be biased by potential endogeneity. Concerned with this problem, we then implement the IV fixed effect estimates and find positive external returns to education at about 10%. We also find this returns differ across individual heterogeneity.
An impact evaluation of Shine Literacy

The recent PIRLS report painted a dire picture of South Africa’s literacy: 80% of Grade 4 learners are unable to read for meaning. With a large body of research confirming how reading literacy holds predictive validity for later child development and academic success, Shine Literacy offers an intervention that is set as a measure for those who struggle to read. This quasi-experimental impact evaluation estimated the treatment effect of Shine Literacy via difference-in-differences. Average treatment effects range between 0.6 to 1.9 standard deviations. IsiXhosa and ‘At risk’ learners are the main beneficiaries of the programme. JEL classifications: D04, H43, I24
On doubly periodic minimal surfaces in H 2 × R with ﬁnite total curvature in the quotient space

In this paper, we develop the theory of properly immersed minimal surfaces in the quotient space ( H 2 × R )/ G , where G is a subgroup of isometries generated by a vertical translation and a horizontal isometry (without ﬁxed points) in H 2 . The horizontal isometry can be either a parabolic translation along horocycles in H 2 or a hyperbolic translation along a geodesic in H 2 . We prove that if a properly immersed minimal surface in ( H 2 × R )/ G has ﬁnite total curvature, then its total curvature is a multiple of 2 π and, moreover, we understand the geometry of the ends. The results hold true more generally for properly immersed minimal surfaces in M × S 1 , where M is a hyperbolic surface with ﬁnite topology whose ends are isometric to one of the ends of the above spaces ( H 2 × R )/ G .
An Estimate of the Heritability of the Corbicular Area of the Honeybee

SummaryHeritability (h2) of corbicular area in worker honeybees (Apis mellifera) was estimated from the variance components of half-sib families. Corbicular area was measured on 30 worker progeny from each of 73 free-mated queens which were the daughters of 8 mother queens. Heritability was estimated to be 1·014 ± 0·195. This large value for h2 indicates that selection for larger corbicular area is possible and, depending upon the genetic correlation, may result in concomitant selection for improved honey production.
