Dietary Effects of Non-native Species on Yellow Perch, Perca flavescens, Reproductive Performance

In Lake Michigan, native yellow perch (Perca flavescens) have experienced poor recruitment since 1989. With the introduction of non-native species yellow perch prey fish have changed dramatically, which could affect successful recruitment of these fish. Therefore, in the present study I investigated dietary effects of two non-native species (alewife and round goby) on female yellow perch reproduction using lipid and fatty acid composition of their eggs, liver, muscle, and visceral fat. Two-year-old yellow perch were fed two diets, representing two distinct fatty acid signatures. These two diets were significantly different, in terms of fatty acid composition, with alewife containing higher concentrations of SAFA and MUFA and round goby having higher concentrations of PUFA. Unexpectedly, the entire dietary fatty acid composition was not reflected in tissues of yellow perch, but some individual dietary fatty acids were incorporated. Biosynthesis of linoleic acid into ARA and linolenic acid into EPA and DHA was also clearly observed in all tissues of yellow perch. Yellow perch fed round goby yielded a significantly higher body mass than yellow perch fed alewife (p 0.05). In conclusion, although round goby and alewife have high levels of n-3 and n-6 fatty acids, (which are general requirements for successful reproduction and recruitment by fish) successful reproduction of all female yellow perch was not observed in the present study. This observation could have been due to poor quality of egg ribbons; indicated by the ribbon separating in several places, and females spawning in tanks, thus limiting our ability to successfully fertilize eggs by hand.
Internal Marketing Practices and Employees' Turnover Intentions in Tourism and Leisure Hotels

In recent years, the government has actively promoted the 2008 National Development Plan and the overall policy of opening the island for tourist from Mainland China. This effort increases the importance of the leisure service industry. The hotel industry is typically a service industry and the service object is “human;” therefore, service quality is decided based on “human” qualities. Thus, the human element is a key resource for the hotel industry. The employee turnover rate of the hotel industry is in the high side, however, which causes higher personnel expenditures and training costs and the probability of losing excellent employees increases. The hotel industry as a whole, therefore, should strengthen its internal marketing efforts aimed at ensuring employees establish a high level of customer-service consciousness, promote service quality, and decrease turnover rates. This study attempts to integrate and discuss the study results and concepts proposed by previous scholars. According to the literature review and questionnaires, this paper will discuss the correlation between internal marketing practices and the employees’ turnover intentions. In addition, this study inserts the concept of work adoptability to discuss the relationship between internal marketing practices and employee turnover intentions at different levels.
Assessing Local Scale Impacts of Opuntia stricta (Cactaceae) Invasion on Beetle and Spider Diversity in Kruger National Park, South Africa

There is a paucity of studies examining direct impacts of introduced alien species on biodiversity, a key need for motivating for alien species control in conservation areas. The introduced prickly pear (Opuntia stricta) has invaded some 35 000 ha of Kruger National Park. We investigated the effect of O. stricta on beetle and spider species assemblages in the Skukuza region of Kruger National Park. We used unbaited pitfall traps over a 12-month period in four treatments of varying O. stricta density. Species richness, species density and abundance of beetles and spiders were compared. A total of 72 beetle and 128 spider species were collected. Species richness and species density for beetles and spiders did not differ significantly across the four treatments. Assemblages for spiders did not differ across treatments but beetle assemblages were significantly different from uninvaded control sites. This study suggests that the current density of O. stricta does not significantly affect spider species richness, density or assemblages but that beetle assemblages are significantly affected.
Influence of arsenic trioxide on the expression of cyclin A in the Jurkat cel line

Improper expression of cell cycle regulators is characteristic for most cancer cells. Cyclins are a group of proteins, with concentration changing in time, which control progression through each phase of the cell cycle. Maximum cyclin A expression falls inside S and at the beginning of M phase. In the S phase cyclin A is responsible for a proper run of the replication process, and together with cyclin B conditions transition into the M phase. Arsenic trioxide (ATO) is an efficient drug used in acute promyelocytic leukemia (AML). Numerous reports point that arsenic trioxide can be applied in therapy of other types of cancer as well. The purpose of these study was to evaluate influence of arsenic trioxide on the expression and localization of cyclin A in Jurkat cell line. Additionally, we determined the effect of ATO on morphology and ultrastructure of the Jurkat cells. In order to reach this aim we applied classic light, florescence and electron transmission microscopy. A dose-dependent decrease in the percentage of viable cells was observed. Morphological and ultrastructural alterations suggest that apoptosis and autophagy are induced by ATO. Image-based cytometry showed high extent of necrotic cells after ATO treatment. A decrease in cyclin A level was observed, but without a change in protein nuclear localization.
Physiological responses of female and male black-lip pearl oysters (Pinctada margaritifera) to different temperatures and concentrations of food

This study was designed to measure responses of four-year-old black-lip pearl oysters (Pinctada margaritifera )t o different temperatures and food concentrations and to identify the energy requirements of each sex. Oysters were fed a monospecific microalgal diet of Isochrysis affinis galbana (T-iso). Measurements of oxy- gen consumption and ingestion rates were carried out at 24 ◦ C and 27 ◦ C and at two algal (T-iso) concentrations: 5000 and 30 000 cell ml −1 . Glycogen content in adductor muscle, absorption efficiency and scope for growth were also es- timated. Females and males responded differently to environmental factors, with food level being the most influential parameter. Oxygen consumption and absorption efficiency were significantly higher in females than in males, but males had significantly higher glycogen content than females. At high food concentration, glycogen content, ingestion rate, oxygen consumption, and scope for growth were significantly higher than at the low food concentration. Only absorp- tion efficiency was significantly higher at the low food concentration. Oxygen consumption was significantly higher at 27 ◦ Ct han at 24 ◦ C. These results indicate that females and males have different bioenergetic functioning and that energy demands for reproduction are higher in females.
Time-resolved flow dynamics and Reynolds number effects at a wall–cylinder junction

This study investigated the physics of separated turbulent flows near the vertical intersection of a flat wall with a cylindrical obstacle. The geometry imposes an adverse pressure gradient on the incoming boundary layer. As a result, flow separates from the wall and reorganizes to a system of characteristic flow patterns known as the horseshoe vortex. We studied the time-averaged and instantaneous behaviour of the turbulent horseshoe vortex using planar time-resolved particle image velocimetry (TRPIV). In particular, we focused on the effect of Reynolds number based on the diameter of the obstacle and the bulk approach velocity, $\mathit{Re}_{D}$ . Experiments were carried out at $\mathit{Re}_{D}$ : $2.9\times 10^{4}$ , $4.7\times 10^{4}$ and $12.3\times 10^{4}$ . Data analysis emphasized time-averaged and turbulence quantities, time-resolved flow dynamics and the statistics of coherent flow patterns. It is demonstrated that two large-scale vortical structures dominate the junction flow topology in a time-averaged sense. The number of additional vortices with intermittent presence does not vary substantially with $\mathit{Re}_{D}$ . In addition, the increase of turbulence kinetic energy (TKE), momentum and vorticity content of the flow at higher $\mathit{Re}_{D}$ is documented. The distinctive behaviour of the primary horseshoe vortex for the $\mathit{Re}_{D}=12.3\times 10^{4}$ case is manifested by episodes of rapid advection of the vortex to the upstream, higher spatio-temporal variability of its trajectory, and violent eruptions of near-wall fluid. Differences between this experimental run and those at lower Reynolds numbers were also identified with respect to the spatial extents of the bimodal behaviour of the horseshoe vortex, which is a well-known characteristic of turbulent junction flows. Our findings suggest a modified mechanism for the aperiodic switching between the dominant flow modes. Without disregarding the limitations of this work, we argue that Reynolds number effects need to be considered in any effort to control the dynamics of junction flows characterized by the same (or reasonably similar) configurations.
Cheap talk with simultaneous versus sequential messages

Recent experimental studies find excessive truth-telling and excessive trust in one sender/one receiver cheap talk games with an essentially unique and babbling equilibrium. We extend this setup by adding a second sender into the play and study the behavior of the players both theoretically and experimentally. We examine games where senders are assumed to communicate with the receiver either simultaneously or sequentially as well as a game where the receiver chooses one of these two communication methods. The theoretical predictions for truth-telling, non-conflicting messages observed and trust frequencies are the same for both the simultaneous and sequential plays; however, we observe systematic differences between the treatments of these plays. While the truth-telling frequencies stay above the theoretical prediction of the one half during all the experiments, the nature of truth-telling seems to differ between sequential and simultaneous plays. Under simultaneous communication, the messages of senders are non-conflictive more than half of the time, while the non-conflicting messages are significantly more likely to be correct than not. The frequency of non-conflicting messages is lower under sequential plays due to the tendency of the second sender to revert the message of the first sender. We observe that subjects who prefer to get non-conflicting messages prefer simultaneous mode of communication more often. When acting as senders, these subjects also adjust their truth-telling frequencies so as to generate conflictive messages.
Endogenous Business Cycle with Search in the Labour Market

We develop an endogenous business cycle (EBC) model with search in the labour market and equilibrium unemployment. Because of the thin market externalities the equilibrium path is indeterminate, and there is a room for sunspot equilibria (extrinsinc uncertainty). Our model generates such business cycles patterns as relative volatility, persistence and comovement in fluctuations of macroeconomic variables, with extrinsic uncertainty being the source of fluctuations. The model is able to predict high autocorrelation in output growth and hump-shaped impulse response of output important business cycle features that existing EBC models, as well as real business cycle models, failed to explain.
Iron-Polyphenol Interaction Reduces Iron Bioavailability in Fortified Tea: Competing Complexation to Ensure Iron Bioavailability

Tea seems to be like a logical substrate for iron fortification; however, its fortification with iron presents technical challenges as tea polyphenols form a blue complex with iron that makes both of them unavailable for absorption. The objective of this work was to develop an effective technology, to prevent the interaction of iron and polyphenols by using EDTA as a competing complexing agent. Fortified tea was prepared from premix, prepared by spraying iron and sodium EDTA into tea leaves. Iron concentration in tea was adjusted to 5 mg/cup. Iron content was measured by AAS and the iron-polyphenol complex by spectrophotometry at 560 nm. Sensory evaluation was carried out in order to determine if fortification affects the properties of tea. A molar ratio of 1 : 2 Fe : EDTA was able to avoid complex formation and provide 4 mg of iron per cup of brewed tea. The fortified tea had a similar colour and flavour as ordinary tea, without the development of off-flavours. However, fortified tea with a ratio lower than 1 : 2 had a darker colour and off-flavours. By the addition of EDTA in a molar ratio ≥1 : 2, it is possible to produce an iron fortified tea without the formation of off-flavours.
Carbonic Anhydrase IX in Adult and Pediatric Brain Tumors

Carbonic anhydrases (CAs) are zinc-containing metalloenzymes present in prokaryotes and eukaryotes (Sly and Hu 1995). CAs have been investigated since 1930 s (Meldrum and Roughton 1933). They are important in normal human physiology, e.g., in gluconeogenesis, lipogenesis, ureagenesis, bone resorption, and formation of gastric juice and cerebrospinal fluid (Sly and Hu 1995, Pastorekova et al. 2004). There are at least 15 members in human alphaCA family: Five active family members are cytosolic (CA I-III, VII, and XIII), four are membrane associated (CA IV, IX, XII, and XIV), two are mitochondrial (CA VA and VB), and one is a secretory form (CA VI). In addition, there are three acatalytic forms, which are called CArelated protein (CARPs). CAs can be categorized to catalytically active or inactive, intracellular or extracellular, and wide-spread or restricted to few tissues.
STUDENTS’ SPECIFIC COMPREHENSION SKILLS IN ENGLISH BASED ON SCHOOL LOCATIONS, GRADES, AND GENDER

Having good English proficiency is a necessity in the 21 st century and students’ comprehension skills must be identified before any teaching is done. Studies that investigate students’ comprehension skills have been conducted over years but the one related to students’ specific comprehension skills in terms of their school locations, grade levels, and gender has not been much discussed. This study aims at investigating 355 junior high school students’ specific comprehension skills as measured by 18 assessments of Warncke Informal Comprehension Assessment (WICA) Instruments (Warncke & Shipman, 1984) based on their school locations (City-based District—CBD, the district which has all levels of education—ALED, and underprivileged-based district—UBD) of Palembang City, grade levels (7 th , 8 th , 9 th ) and gender in a developing country context. The findings show that students’ comprehension achievement is in average level with those from CBD neighborhood have better mean score than those from the other two locations respectively and higher graders have higher achievements. In terms of gender, females is better than that of males. While the highest students’ achievements are on multiple meanings and context and details, the lowest one is on affixes, and the most influential factors on comprehension are school locations and grades. These results lead to the conclusion that students’ comprehension should be enhanced and good school environment provided. It also suggests that the degree of difficulty of the materials match students’ grade-level and students be taught using more innovating strategies to achieve the best comprehension and eventually applicable outcome.
Future Changes in Surface Runoff over Korea Projected by a Regional Climate Model under A1B Scenario

This study assesses future change of surface runoff due to climate change over Korea using a regional climate model (RCM), namely, the Global/Regional Integrated Model System (GRIMs), Regional Model Program (RMP). The RMP is forced by future climate scenario, namely, A1B of Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4). The RMP satisfactorily reproduces the observed seasonal mean and variation of surface runoff for the current climate simulation. The distribution of monsoonal precipitation-related runoff is adequately captured by the RMP. In the future (2040–2070) simulation, it is shown that the increasing trend of temperature has significant impacts on the intra-annual runoff variation. The variability of runoff is increased in summer; moreover, the strengthened possibility of extreme occurrence is detected in the future climate. This study indicates that future climate projection, including surface runoff and its variability over Korea, can be adequately addressed on the RMP testbed. Furthermore, this study reflects that global warming affects local hydrological cycle by changing major water budget components. This study adduces that the importance of runoff should not be overlooked in regional climate studies, and more elaborate presentation of fresh-water cycle is needed to close hydrological circulation in RCMs.
Seed Oil of Morinda citrifolia L. as a Surfactant for Deinking Flotation

Surfactants are essential in the pulp recovery process for the removal of ink on paper to be recycled. In order to create a “green” surfactant, seed oil was extracted from Morinda citrifolia L. by Soxhlet extraction for 4–8 h and its composition evaluated by gas chromatography-mass spectrometry (GC-MS). The total ion chromatogram (TIC) of fatty acids of Morinda citrifolia L. (FAMC) indicated that extraction yields the largest amount of unsaturated fatty acids (UFA), specifically C19H34O2 and C21H38O2, at 6 h. All FAMC fractions were evaluated for their suitability as a surfactant for deinking flotation. FAMC isolated after 6 h of extraction yields fatty acids that are the most suitable surfactants, as the fraction consists of mostly unsaturated fatty acids that show good interactions with the structure of common ink molecules. Our results show that the performance of the FAMC taken after 6 h of extraction approaches that of a synthetic surfactant (SS). The appropriate viscous force for deinking flotation was found to be 1.5–2.0 × 10−4 mg/mm s2 when the synthetic surfactant is used compared to 1.0–1.5 × 10−4 mg/mm s2 for FAMC. The higher intermolecular bonding strength in the synthetic surfactant-ink particle system requires higher viscous force.
Herschel-ATLAS/GAMA: How does the far-IR luminosity function depend on galaxy group properties?

We use the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) Phase I data to study the conditional luminosity function of far-IR (250 μm) selected galaxies in optically selected galaxy groups from the Galaxy And Mass Assembly (GAMA) spectroscopic survey, as well as environmental effects on the far-IR-to-optical colour. We applied two methods, which gave consistent results for the far-IR conditional luminosity functions. The direct matching method matches H-ATLAS sources to GAMA/SDSS (Sloan Digital Sky Survey) galaxies, then links the optical counterparts to GAMA groups. The stacking method counts the number of far-IR sources within the projected radii of GAMA groups, subtracting the local background. We investigated the dependence of the far-IR (250 μm) luminosity function on group mass in the range 1012 1012 h−1 M⊙. We also find that the far-IR-to-optical colours of H-ATLAS galaxies are independent of group mass over the range 1012 < Mh < 1014 h−1 M⊙ in the local Universe. We also compare our observational results with recent semi-analytical models, and find that none of these galaxy formation models can reproduce the conditional far-IR luminosity functions of galaxy groups.
Comparison of lipid profiles and 10 year cardiovascular disease risk estimates between indigenous northern diabetic and non-diabetic persons in Adamawa region, Cameroon

Dyslipidemias are possible debilitating outcomes of diabetes and important predictors of cardiovascular disease risk in diabetic patients. We carried out a cross-sectional, case control study from April to July 2014 at the Ngaoundere Regional Hospital involving 90 patients: 45 diabetics (10 type 1 and 35 type 2) and 45 non-diabetics with the aim of characterizing and comparing the lipid profile between type 1 and type 2 diabetics of northern Cameroon. Blood pressure and anthropometric measurements were obtained, and a fasting blood sample collected per patient on which blood sugar level and lipid profile were determined. Data analysis was performed using R Version 2.13. 0 and the French version of Epi Info 7, with the level of significance set at 5%. Following threshold standards according to ANAES, the mean triglyceride level was significantly higher in type 2 diabetics (212.65±49.34 mg/dL) compared to type 1 diabetics (101.60±52.64 mg/dL) and controls (152.24±57.91 mg/dL) (p<0.0014). The mean low density lipoprotein (LDLc) was observed to be significantly higher in type 1 (136.78± 33.88 mg/dL) compared to type 2 (113.29 ± 38.00 mg/dL) diabetics and controls (94.62 ± 51.31 mg/dL) (P = 0.017), and likewise the median high density lipoprotein (HDLc) of type I, type II, and non-diabetics corresponding to 11.5, 47 and 56 mg/dl respectively were significantly different (p<0.0001). Furthermore, mixed hyperlipidemia was absent among the type 1 diabetics but more prevalent in type 2 diabetics (37.1 %) compared to controls (6.7%). According to the D’Agostino (Framingham) model, 37.1% of type II diabetics and 6.8 % of non-diabetics had a high risk of developing cardiovascular disease in 10 years, and the difference here was statistically significant (p=0.001). Both type 1 and type 2 diabetics originating from northern Cameroon are very prone to dyslipidemias and thus highly predisposed to cardiovascular diseases.

Is Green the New Black? Assessing Textile & Apparel Undergraduate Students’

Many textile and apparel manufacturers are attempting to address consumer demand for environmentally friendly products. Concurrently, a number of textile and apparel programs are incorporating environmental responsibility into the curriculum. However, educators do not fully understand the results of these efforts in terms of providing our students with the environmental knowledge necessary to influence concern for the environment and ultimately, environmentally responsible behavior. This exploratory study investigates textile and apparel undergraduate students’ environmental knowledge, concern and responsibility. Findings suggest that teaching students about environmental responsibility in school is more effective in promotion responsible behavior as compared to students learning through the mass media. Moreover, the findings suggest that students’ knowledge, concern and behavior do not differ based on the grade level when the concept of environmental responsibility is first introduced. In addition, students majoring in production-oriented areas of apparel and textiles tend to exhibit greater levels of concern and behavior as compared to their counterparts majoring in distribution-oriented areas. Lastly, relatively few students believe they are learning enough about environmental responsibility in apparel and textile courses.
