What Really Affects Student Satisfaction? An Assessment of Quality through a University-Wide Student Survey

The analysis of students satisfaction for their university experience is important within the educational evaluation. In this study was explored the satisfaction of students to identify which aspects of teaching may be cause of dissatisfaction. A survey questionnaire contains items on motivations, teaching quality and services was compiled in anonymous by the students that attending the courses of the Faculty of Science (University of Sassari, Sardinia) during the second semester of the 2009/2010 academic year. The internal consistency of the questionnaire was assessed by Cronbach’s Alpha. A preliminary chi square test at stepwise logistic regression analysis was applied to evaluate the association between student satisfaction and motivation, quality of teacher and services, at a 0.05 significance level. Only 403 questionnaires were considered good with a response rate of 82.6%. The student’s satisfaction is significant different by gender (p = .009). Significant are the items on the interest for scientific studies, the acquisition of the degree as social prestige and future work (p < .05); also, the ability of teacher to stimulate and attract the student, the encouragement, the advice to the students and the his professionality are significantly associated with the students satisfaction (p < .05). In males the main factor associated to the satisfaction is to have achieved always good results in school (OR = 2.84, p = .036); instead, in females, the interest in science (OR = 4.75, p = .023), the title of degree to acquire a social prestige (OR = 2.00, p = .033) and the possibility of a future work (OR = 2.09, p = .028). Although good judgments made by students, however, require further attention, such as such as the abandonment of the university, the time of graduation degree, the future career, for better analysis of aspects related to the satisfaction of the quality of teaching.

The Interval Dissonance Rate: An Analytical Look into Chromaticism of Chopin’s Op. 10 No. 2 and Scriabin's Op. 11 No. 2

The concept of dissonance and consonance in music is established from two or more simultaneous notes. There are multiple approaches into dissecting this concept; some of these are acoustical, psychological, and mathematical. We developed an Interval Dissonance Rate (IDR) – an innovative tool that integrates musical and mathematical analyses in non-monophonic Western music, using interval vectors and the frequency of recurrent pitches in the vectors to determine the percentage of dissonant and consonant intervals. Two tonal pieces with musical chromaticism by Frédéric Chopin and Alexander Scriabin are used for IDR analysis. According to results, the IDR of Chopin’s Étude Op. 10 No. 2 is equal to 17.65%, while the IDR of Scriabin’s Prelude Op. 11 No. 2 is equal to 29.37%. The IDR also allows one to look for intervallic patterns of various composers and in music of specific genres.
Acquisition of syntactic topic marking

1994). Marking the sentence topic can be done syntactically, lexically, morphologically, or phonologically. This article focuses on syntactic topic marking. Syntactic topic marking has two sides, a pragmatic side and a syntactic side. The pragmatic notion topic may be universally available to the language user, whereas its formal, syntactic expression is language specific. (Hendriks 2000:392). Also, within the 3
Impact of the large-scale environment on the tonal noise of axial fans

The measurement of the sound emission of axial fans is standardized by internationally accepted guidelines. While it is known that the sound emission of fans is significantly influenced by the inflow conditions, the standards address this issue barely. A detailed definition of the inflow conditions for standardized acoustic measurements of axial fans does not exist. In this investigation, it is shown that disturbed inflow conditions exist even when the test rig meets the requirements of the current standards. Flow visualization and RANS simulation reveal unexpected vortex-like flow structures at the intake and inside the duct originating in the large anechoic chamber. These large-scale eddies in the inflow are also recognized by flush mounted pressure transducers on the blade surface of the impeller. It turns out that a hemispherical inflow control device may be suitable to get closer to the state of test rig independent acoustic measurements of axial fans.
What Characterizes Excessive Online Stock Trading? A Qualitative Study

Excessive online stock trading appears to share similarities with gambling disorder. However, using gambling disorder criteria to assess excessive trading may not allow a full understanding of this phenomenon as specific aspects of the trading context that differ from gambling may be overlooked. This study explores the manifestations and consequences of excessive trading and its links with gambling disorder via the perceptions of online stock traders themselves. Data for thematic analysis were collected from a sample of online stock traders ( N = 13) divided into two focus groups based on trading frequency (i.e., on a regular or occasional basis). Perceived manifestations of excessive trading included excessive preoccupation and frequent behaviors, and consequences that affect finances, relationships, work and health. Perceived links between gambling disorder and excessive trading concerned a shared incapacity to control behaviors, and chasing losses. Though excessive trading and gambling disorder are similar on many grounds, the assessment of trading behaviors should consider specific aspects such as the context within which they occur (e.g., state of the market). Implications for future research on excessive trading behaviors are discussed. Resume Les transactions d’actions excessives peuvent presenter des similitudes avec le jeu pathologique. Cependant, appliquer des criteres propres au jeu pathologique a des pratiques de transactions excessives en ligne ne permet pas necessairement de bien comprendre ce phenomene, car il pourrait arriver qu’on neglige certains aspects particuliers du contexte transactionnel qui different du contexte du jeu. Cette etude explore les manifestations et les consequences de pratiques transactionnelles excessives et ses liens avec le jeu pathologique, en se penchant sur les perceptions personnelles des negociateurs. Les donnees ont ete recueillies pour une analyse thematique a partir d’un echantillon de negociateurs en ligne ( N = 13), divise en deux groupes de discussion en fonction de la frequence des transactions (soit sur une base reguliere ou occasionnelle). Parmi les manifestations percues a propos de transactions excessives, on a pu voir des preoccupations excessives et de frequents comportements et leurs consequences sur les finances, les relations, le travail et la sante. Les liens communs percus entre les troubles du jeu et la negociation excessive etaient l’incapacite a controler ses comportements et la recuperation des pertes. Bien que la negociation excessive et les problemes du jeu soient semblables sous divers aspects, l’evaluation de comportements de negociateurs devrait prendre en compte des aspects particuliers tels que le contexte dans lequel ces comportements se manifestent (par exemple, l’etat du marche). Dans l’etude, on aborde aussi la portee de futures recherches sur les comportements de negociation excessive.
Balconies , analysis of constructive technology current state and foresight of new industrial development

Despite being an essential part of the Mediterranean facade, the balcony has been relegated to a background in the recent technological evolution of the envelope of the buildings constructed in Spain since the end of the 20th century. In the same way that technician solutions for roofing and facades have been intensively developed, is the balcony destined to be industrialized as any other element? If so, could it become industrialized? And how should it be? Who must generate it?

Anti-inflammatory effect of oleanoic acid 28-O--D-glycopyranosyl ester isolated from Aralia cordata in activated HMC-1 cells

Aralia cordata is known in traditional Korean medicine as a remedy for arthritis. As a part of our program to screen medicinal plants for potential anti-inflammatory compounds, oleanoic acid 28-O-β-D-glycopyranosyl ester (OA) was isolated from the roots of Aralia cordata. So, the immune modulation molecular mechanism of OA isolated from A. cordata was studied.One of the possible mechanisms for its protective activities is by down regulation of the inflammatory responses. Therefore, cells from the human mast cell line (HMC-1) were used to investigate this effect. OA significantly inhibits the way in which phorbol 12-myristate 13-acetate (PMA) plus A23187 induces the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-8 and intracellular Ca2+ levels. In activated HMC-1 cells, phosphorylation of extra-signal response kinase (ERK) 1/2, degradation of IκB, and activation of NF-κB decreased after treatment with OA. OA suppressed the expression of TNF-α, IL-6 and IL-8 through a decrease in the intracellular levels of Ca2+ and ERK 1/2, as well as activation of NF-κB. These results indicated that OA exerted a regulatory effect on inflammatory reactions mediated by mast cells. Key words: Oleanoic acid 28-O-β-D-glycopyranosyl
Quantum cryptanalysis of block ciphers

Grover invented a quantum algorithm that ﬁnds a solution in only $O( \sqrt{2^{n}})$ steps whereas the exhaustive search algorithm needs $O(2 ^{n})$ steps on average. Brassard, $ \mathrm{H}\emptyset\mathrm{y}\mathrm{e}\mathrm{r}$ , Tapp construct an algo-rithm that counts the number of the solutions for a searching problem. We discuss two applications of quantum algorithms to information security; the ﬁrst is the cryptanalysis of block ciphers using Grover’s algorithm and the second is the strength evaluation of block ciphers using Brassard, $ \mathrm{H}\emptyset\mathrm{y}\mathrm{e}\mathrm{r}$ , Tapp’s algorithm.
Expression of bradykinin in human placenta from healthy and preeclamptic women

This study evaluated the expression of bradykinin (BK) in human placenta from healthy and preeclamptic women. This is a non-randomized experimental study, in which we performed histological analysis of placental tissue to observe changes that occur in each kind of placenta as well as immunohistochemical analysis to investigate the expression of bradykinin. We used ‘Paleontological Statistics software package for education and data analysis’ 3.06 and R for the statistical analysis. The Ethics Committee of the University of Rio Grande do Norte State approved this experiment under protocol number 166370, according to the determinations established by Resolutions 466/12 and 441/11.We found differences between the two kinds of placenta concerning the diameter of the vessels and the rate of cytotrophoblastic invasion. Student’s t-test evidenced significant difference (p = 7.6395 x 10 -5 ) indicating greater marking of BK per section in the healthy placenta group. The result of more significant expression of bradykinin in healthy placenta can be used as a starting point for deeper researches aiming to better characterize and quantify this expression.
POPULATION STRUCTURE OF CAITIPA MOJARRA (Diapterus rhombeus) IN AN ESTUARINE SYSTEM OF SOUTHEASTERN BRAZIL

Santos estuary suffers anthropic influence through various activities, including fisheries. Caitipa mojarra (Diapterus rhombeus) is among the exploited resources of the region and, despite its importance, it still has not been well studied. The main goal of this study was to analyze the population structure of this species regarding gonadal development, age and growth. For the analysis of gonadal development, samplings were carried out between November 2008 and August 2011, gathering in total 6,639 individuals. The age and growth parameters were analyzed from a data base of the species, which contained information from samplings from October 2007 to September 2011. Most of the specimens caught (71.93%) was considered juvenile and only 0.68% were spawning. From gonadal maturity, sexual proportion and length classes of the individuals, it could be seen that this species does not spawn within Santos estuary. The growth parameters estimates were L∞ of 262.5 mm, k = 0.24/year and longevity of 12.48 years.
Host hybridization alters specificity of cnidarian–dinoflagellate associations

Scleractinian coral evolution is often characterized by alternating patterns of lineage diversification and fusion, thus leading to reticulate evolution. Although this pattern is hypothesized in many coral lineages, including the Montastraea annularis species complex, it is not known what effects cladogenesis and hybridization have on the symbioses between corals and their endosymbi- otic dinoflagellates (genus Symbiodinium). To explore this, the genetic diversity of M. faveolata and M. annularis in the Upper Florida Keys, USA, and Exuma Cays, The Bahamas, was examined using a mtDNA intergenic region. The host genotypic data were then analyzed in relation to the diversity of the corals' Symbiodinium communities as determined by internal transcribed spacer region 2 (ITS2) and 3 microsatellite markers specific to Symbiodinium Clade B. M. faveolata and M. annularis in the Upper Florida Keys were genetically distinct from one another while these coral species in the Exuma Cays shared mtDNA haplotypes. These findings suggest possible regional differences in the degree of intergressive hybridization between M. faveolata and M. annularis. When Symbiodinium diversity was examined, Montastraea spp. from both regions shared Symbiodinium ITS2 genotypes; however, host-symbiont specificity was observed using higher resolution microsatellite markers. Specifically, M. faveolata and M. annularis from the Upper Florida Keys all harbored genetically dis- tinct multilocus Clade B genotypes, whereas these 2 coral species in the Exuma Cays shared Clade B genotypes. Consequently, the degree of fine-scale specificity between Symbiodinium Clade B geno- types and Montastraea spp. appears to be governed by the degree of genetic distinction, and possi- bly hybridization, between these host 'species'.
Robust Seasonality of Arctic Warming Processes in Two Different Versions of the MIROC GCM

AbstractIt is one of the most robust projected responses of climate models to the increase of atmospheric CO2 concentration that the Arctic experiences a rapid warming with a magnitude larger than the rest of the world. While many processes are proposed as important, the relative contribution of individual processes to the Arctic warming is not often investigated systematically. Feedbacks are quantified in two different versions of an atmosphere–ocean GCM under idealized transient experiments based on an energy balance analysis that extends from the surface to the top of the atmosphere. The emphasis is placed on the largest warming from late autumn to early winter (October–December) and the difference from other seasons. It is confirmed that dominating processes vary with season. In autumn, the largest contribution to the Arctic surface warming is made by a reduction of ocean heat storage and cloud radiative feedback. In the annual mean, on the other hand, it is the albedo feedback that contributes the mo.

The Scottish University Level Entrepreneurship Education Initiative: Lessons for Ghana in Dealing with Graduate Unemployment

The aim of the study was to investigate entrepreneurship education at the university level in Scotland and lessons Ghana could learn from their experience in solving graduate unemployment. The main data used for the study was primary, collected through interviews with six academics involved in university level entrepreneurship education at four universities in Scotland. Qualitative approach was used for this research so as to have a first-hand perception of academics on the entrepreneurship education at the university level. Scottish Enterprise is using entrepreneurship education at the university level as a policy strategy for increasing business birth rate among Scottish university graduates. It clearly emerged from the perspective of academics that entrepreneurship education at the university level cannot significantly lead to business start-ups and therefore cannot be used as a strategy for self-employment among graduates. It became therefore evident that entrepreneurship education cannot be used as a sole strategy for solving unemployment; it can though equip students with some employability skills. The lessons that Ghana can learn from the Scottish experience is that entrepreneurship education could equip students with some enterprise skills (which are needed by employers in Ghana) that would make them employable, thereby contributing to solving graduate unemployment in Ghana. Keywords : enterprise and entrepreneurship education, universities, unemployment, Scotland, Ghana, graduates.
The role of organisational justice on employee engagement within a public service organisation in South Africa

The objective of this study was to explore the relationship between organisational justice and employee engagement in a South African public service organisation. The Organisational Justice Measurement Instrument (OJMI) was used as a measure of organisational justice and Utrech Work Engagement Scale measured the participants’ levels of work engagement. These measuring instruments were administered to a random sample size of public service organisation employees (n=289). Descriptive statistics and correlational analysis were conducted to analyse the data. The results of the correlational analysis indicated a significant correlations between organisational justice and work engagement dimensions namely; vigour, dedication and absorption. In terms of contributions and practical implications, insight gained from the findings may be used in proposing organisational development interventions to enhance employees’ work engagement levels as well as to conduct future research.
Assessing the uncertainty of glacier mass-balance simulations in the European Arctic based on variance decomposition

Abstract. State-of-the-art numerical snowpack models essentially rely on observational data for initialization, forcing, parametrization, and validation. Such data are available in increasing amounts, but the propagation of related uncertainties in simulation results has received rather limited attention so far. Depending on their complexity, even small errors can have a profound effect on simulations, which dilutes our confidence in the results. This paper aims at quantification of the overall and fractional contributions of some archetypical measurement uncertainties on snowpack simulations in arctic environments. The sensitivity pattern is studied at two sites representing the accumulation and ablation area of the Kongsvegen glacier (Svalbard), using the snowpack scheme Crocus. The contribution of measurement errors on model output variance, either alone or by interaction, is decomposed using global sensitivity analysis. This allows one to investigate the temporal evolution of the fractional contribution of different factors on key model output metrics, which provides a more detailed understanding of the model's sensitivity pattern. The analysis demonstrates that the specified uncertainties in precipitation and long-wave radiation forcings had a strong influence on the calculated surface-height changes and surface-energy balance components. The model output sensitivity patterns also revealed some characteristic seasonal imprints. For example, uncertainties in long-wave radiation affect the calculated surface-energy balance throughout the year at both study sites, while precipitation exerted the most influence during the winter and at the upper site. Such findings are valuable for identifying critical parameters and improving their measurement; correspondingly, updated simulations may shed new light on the confidence of results from snow or glacier mass- and energy-balance models. This is relevant for many applications, for example in the fields of avalanche and hydrological forecasting.
Ku-band InGaP-GaAs HBT MMIC VCOs with balanced and differential topologies

Balanced and differential voltage controlled oscillators (VCOs) are investigated with analytic noise models. Fully integrated VCOs in Ku-band are implemented on an InGaP-GaAs heterojunction bipolar transistor technology. The balanced VCO has higher output power and lower phase-noise performance, while drawing lower current than the differential VCO. This coincides with the analytical expectation. The shot noise of collector current contributes less to the phase noise in the balanced VCO (B-VCO) than in the differential VCO. The B-VCO shows 2-3 dB lower phase-noise performances of 90.5, -113.8dBc/Hz at the offset frequencies 100 kHz, and 1-MHz offset at 13.5 GHz than the differential VCO, and figures of merit of 180.7 and -177.6dBc/Hz are achieved, respectively.
Education Franchising in Australia: Can Teachers be Successful Franchisees?

Educational franchising is an emerging area in the fast growing services sector. However, no empirical research has been done in exploring whether franchising is a suitable business structure for distributing quality educational services. Four children’s education franchisors in Australia were interviewed for this qualitative study to determine aspects of the business relationship between the franchisor and franchisee. The findings reveal that while the franchising structure supports the teaching and distribution of quality education as well as providing a vehicle for cost effective expansion, more business skills are needed by the franchisees. Franchisors feel that the teacher franchisees need to be skilled business people to support the educational franchising system more effectively.
