The impact of work-based research projects at postgraduate level

Purpose The purpose of this paper is to examine the impact of work-based research projects at postgraduate level. The focus of this paper is to measure the impact of masters- and doctoral-level work-based projects which was the specific contribution of one group of researchers to the Nixon et al.’s (2008) study. Design/methodology/approach This paper is based on data generated as part of a wider study that examines the impact of work-based learning projects across undergraduate through to doctoral level from the perspective of employers and from the employees perspective. The research study is based on a sample of alumni who had graduated from work-based masters and professional doctorate programmes and their corresponding employers in a UK higher education institution. Findings At masters and doctorate level the work-based project can often make an impact on the work context and also have a developmental effect on the employee who becomes a practitioner-researcher to undertake the project.

The Relation between Teachers’ Perception of Ethical Leadership, Organizational Justice and Organizational Cynicism

The purpose of this study is to examine the relation between middle school teachers’ perception of ethical leadership, organizational justice, and organizational cynicism. Participants of the study are teachers from schools located in Osmaniye downtown in 2014-2015 academic year. These schools were chosen randomly by using simple random sampling method and 386 teachers working in these schools were participants of this study. Data were gathered by using “Ethical Leadership Scale”, “Organizational Justice Scale” and “Organizational Cynicism Scale”. In this study, relational scanning method was used. Study shows that there is a positive and significant relation between teachers’ ethical leadership perception and organizational justice. However, ethical leadership and organizational justice have a negative significant relationship. Results show that the relation between all sub dimensions is significant. Ethical leadership and organizational justice are predictors of the organizational cynicism. Besides, it is resulted that organizational justice has a mediator role between ethical leadership and organizational cynicism.
Laboratory gouge friction: Seismic‐like slip weakening and secondary rate‐ and state‐effects

We investigate experimentally the frictional response of a thick sample of simulated fault gouge submitted to very high shear displacements (up to 40 m) in an annular simple shear apparatus (ACSA). The frictional strength of our granular material exhibits velocity‐weakening consistent with classical rate‐ and state‐dependent friction laws. The length scale involved in the latter phenomenon is dc = 100 μm. However, the evolution of friction is largely dominated by a significant slip‐weakening active over decimetric distances (L = 0.5 m). Interestingly, these decimetric frictional length scales are quantitatively compatible with those estimated for natural faults. During shearing, a thin and highly‐sheared layer emerges from the thick and slowly‐deforming bulk of the sample. Because of the intermittent and non‐local coupling observed between these two zones, we relate the large frictional length scales in our data to the slow structuring of the thick interface.
VALIDATION OF THE TECHNOLOGY ACCEPTANCE MODEL FOR INTERNET TOOLS

The Technology Acceptance Model (TAM) has been widely examined by information systems (IS) researchers with inconclusive findings. This research uses confirmatory factor analysis and structural equation modeling techniques to validate the model in the context of Internet tools. It finds strong support for the model even under perturbations of gender, age, experience, and intention of use of the respondents. The study thus reaffirms the importance of TAM in IS research and the model's relevance to Internet technologies.
The Effect of Human Resource Management Practices on Employee Outcomes: A Study of Firms Listed on the Nairobi Securities Exchange

Most empirical research on the link between Human Resource Management Practices (HRMP) and employee outcomes has concentrated on the private sector, yet understanding this relationship in publicly listed firms, in the Developing World context is equally important. The effect of HRMP on employee outcomes - has not been established amongst Nairobi Securities Exchange (NSE) listed firms, yet theory has demonstrated that HRMP can have an effect on employee outcomes. This study was motivated by the desire to fill this gap in knowledge. The study objective was to assess the relationship between HRMP and employee outcomes. The research design was cross sectional descriptive survey. Data was collected using a self-administered questionnaire, from a population of 60 NSE listed firms. The response rate was 36(60%). Descriptive statistics, correlation and regression techniques were used to analyze the data. The results indicate that HRMP have a significant effect on employee outcomes. This study confirms the findings of previous studies that have found a significant link between HRMP and employee outcomes. It was recommended that firms have to ensure that they formulate Human Resource Management Practices that will lead to employee outcomes that can enhance employee commitment, competence and empowerment. This will assist the firms towards attainment and sustenance of superior and competitive advantage in their activities. Keywords: Human Resource Management Practices (HRMP); Employee Outcomes; Nairobi Securities Exchange (NSE)
Nonlinear dynamics of sand banks and sand waves

Sand banks and sand waves are two types of sand structures that are commonly observed on an off-shore sea bed. We describe the formation of these features using the equations of the fluid motion coupled with the mass conservation law for the sediment transport. The bottom features are a result of an instability due to tide–bottom interactions. There are at least two mechanisms responsible for the growth of sand banks and sand waves. One is linear instability, and the other is nonlinear coupling between long sand banks and short sand waves. One novel feature of this work is the suggestion that the latter is more important for the generation of sand banks. We derive nonlinear amplitude equations governing the coupled dynamics of sand waves and sand banks. Based on these equations, we estimate characteristic features for sand banks and find that the estimates are consistent with measurements.
A Comment on "Family Ruptures, Stress, and the Mental Health of the Next Generation"

Persson and Rossin-Slater (2016b) claim to provide the first causal estimates of the effects of fetal stress exposure on mental health later in life. They emphasize that their analysis is the first to address non-random exposure to a relative’s death and the endogeneity of gestation length to fetal stress. In light of discoveries regarding prior literature, we find these claims to be exaggerated and misleading.
A TWO STAGE MODEL OF ON LINE PROCESSING DURING THE READING OF SHORT STORIES A Dissertation Presented

Two experiments were conducted to explore whether readers' on line word processing is affected by lexical and contextual variables. Word frequency (Experiment 1) and factivity (Experiment 2) were manipulated to explore lexical processing. Predictability (Experiment 1) and correctness (Experiment 2) was varied to assess readers' context dependent word interpretation. The results showed that word frequency as well as predictability and correctness manipulations effectively biased readers' fixation time. Low frequency, low predictable and incorrect words received longer fixation times than high frequency, high predictable and correct words. Moreover, a central mask that moved in synchrony with the readers' eyes combined additively with word frequency but interacted with pr edictabli ty and correctness. Based on this it was concluded that two autonomous cognitive subroutines affect the on line processing of words during the reading of text; one stage which mediates the processing of individual word characteristics (lexical look-up) and one stage which integrates individual words into the conceptual frame of text.
Tropical Cyclone Climatology in a Global-Warming Climate as Simulated in a 20 km-Mesh Global Atmospheric Model: Frequency and Wind Intensity Analyses

Possible changes in the tropical cyclones in a future, greenhouse-warmed climate are investigated using a 20 km-mesh, high-resolution, global atmospheric model of MRI/JMA, with the analyses focused on the evaluation of the frequency and wind intensity. Two types of 10-year climate experiments are conducted. One is a present-day climate experiment, and the other is a greenhouse-warmed climate experiment, with a forcing of higher sea surface temperature and increased greenhouse-gas concentration. A comparison of the experiments suggests that the tropical cyclone frequency in the warm-climate experiment is globally reduced by about 30% (but increased in the North Atlantic) compared to the present-day-climate experiment. Furthermore, the number of intense tropical cyclones increases. The maximum surface wind speed for the most intense tropical cyclone generally increases under the greenhouse-warmed condition (by 7.3 m s - 1 in the Northern Hemisphere and by 3.3 m s - 1 in the Southern Hemisphere). On average, these findings suggest the possibility of higher risks of more devastating tropical cyclones across the globe in a future greenhouse-warmed climate.
Integrated approaches for predicting soil-water characteristic curve and resilient modulus of compacted fine-grained subgrade soils

This paper combines a series of approaches for predicting the soil-water characteristic curve (SWCC) and the variation of the resilient modulus (MR) of compacted fine-grained subgrade soils with moisture content, which is the key information required in mechanistic pavement design methods. The presented approaches for the SWCC and MR are integrated, as (i) they are developed following the same philosophy, (ii) they require only the measurements of the suction and moisture content or MR at saturated and optimum moisture content conditions for prediction, and (iii) the predicted SWCC is used for predicting the MR – moisture content relationship. Experimental studies have been performed on five fine-grained subgrade soils that were collected from different regions in Ontario, Canada, to determine their MR at various external stress levels and post-compaction moisture contents, as well as their SWCCs after the MR tests. Experimental measurements are predicted using the integrated approaches and the empirical .
No assembly required: mergers are mostly irrelevant for the growth of low-mass dwarf galaxies

Author(s): Fitts, A; Boylan-Kolchin, M; Bullock, JS; Weisz, DR; El-Badry, K; Wheeler, C; Faucher-Giguere, CA; Quataert, E; Hopkins, PF; Keres, D; Wetzel, A; Hayward, CC | Abstract: © 2018 The Author(s). Published by Oxford University Press on behalf of The Royal Astronomical Society. We investigate the merger histories of isolated dwarf galaxies based on a suite of 15 highresolution cosmological zoom-in simulations, all with masses of Mhalo ≈ 1010M⊙ (and M* ~ 105 - 107M⊙) at z= 0, from the Feedback in Realistic Environments project. The stellar populations of these dwarf galaxies at z= 0 are formed essentially entirely 'in situ': over 90 per cent of the stellar mass is formed in the main progenitor in all but two cases, and all 15 of the galaxies have g 70 per cent of their stellar mass formed in situ. Virtually all galaxy mergers occur prior to z~ 3, meaning that accreted stellar populations are ancient. On average, our simulated dwarfs undergo five galaxy mergers in their lifetimes, with typical pre-merger galaxy mass ratios that are less than 1:10. This merger frequency is generally comparable to what has been found in dissipationless simulations when coupled with abundance matching. Two of the simulated dwarfs have a luminous satellite companion at z= 0. These ultra-faint dwarfs lie at or below current detectability thresholds but are intriguing targets for nextgeneration facilities. The small contribution of accreted stars makes it extremely difficult to discern the effects of mergers in the vast majority of dwarfs either photometrically or using resolved-star colour-magnitude diagrams (CMDs). The important implication for near-field cosmology is that star formation histories (SFHs) of comparably massive galaxies derived from resolved CMDs should trace the build-up of stellar mass in one main system across cosmic time as opposed to reflecting the contributions of many individual SFHs of merged dwarfs.
Assessment of Prevalence, Knowledge, Attitude, and Psychosocial Impact of Acne Vulgaris among Medical Students in Saudi Arabia

Objective: To evaluate the prevalence of acne vulgaris among medical students in Saudi Arabia and to assess their knowledge and attitudes about it, as well as the psychosocial impact of acne. Methods: Data was collected from 555 medical students, both males and females, in Saudi Arabia. A cross sectional design was used. Questionnaires were used to collect data. Results: Of the participants 49.5% were male and 50.5% female. More than half of the participants (66.7%) were between 18 and 20 years old. The majority were single (91.4%). The geographical areas where they lived included the north (30.3%), south (13.3 %), central (9.4%), east (17.3%), and west (19.1). About two thirds were in the fourth year of medical school or less. Among the participating medical student, 55% had acne. The most common site affected was the face, and the least affected was the chest. More than half of medical students in the study sample used medical lotions to treat acne (57.0%), with only one third using medication (33.1%). Perceived adverse psychological effects were self-reported by 202 students, 72.1% of the 305 with acne. Most (91.4%) identified hormones as the most important aggravating factor. Other aggravating factors believed by students included change in stress (86.1%), dust and heat (84.9%), cosmetics (69.2%), and lack of care skin and diet (66.8%). Gender were significantly related to the level of knowledge score, with the majority of male students (62.5%) having poor knowledge about acne while 50.9% of the female students had good knowledge. Age, social status, living area, and study year were not significantly associated with knowledge level of participants. Conclusion: Results of this study point out that lack of knowledge about acne is widespread among Saudi medical students, and patients with acne had poor practice and unfavorable attitude.
Rosetta mission results pre-perihelion Special feature Dark side of comet 67 P / Churyumov-Gerasimenko in Aug . – Oct . 2014 MIRO / Rosetta continuum observations of polar night in the southern regions

The high obliquity (∼50◦) of comet 67P/Churyumov-Gerasimenko (67P) is responsible for a long-lasting winter polar night in the southern regions of the nucleus. We report observations made with the submillimeter and millimeter continuum channels of the Microwave Instrument onboard the Rosetta Orbiter (MIRO) of the thermal emission from these regions during the period AugustOctober 2014. Before these observations, the southern polar regions had been in darkness for approximately five years. Subsurface temperatures in the range 25−50 K are measured. Thermal model calculations of the nucleus near-surface temperatures carried out over the orbit of 67P, coupled with radiative transfer calculations of the MIRO channels brightness temperatures, suggest that these regions have a thermal inertia within the range 10−60 J m−2 K−1 s−0.5. Such low thermal inertia values are consistent with a highly porous, loose, regolith-like surface. These values are similar to those derived elsewhere on the nucleus. A large difference in the brightness temperatures measured by the two MIRO continuum channels is tentatively attributed to dielectric properties that differ significantly from the sunlit side, within the first few tens of centimeters. This is suggestive of the presence of ice(s) within the MIRO depths of investigation in the southern polar regions. These regions started to receive sunlight in May of 2015, and refinements of the shape model in these regions, as well as continuing MIRO observations of 67P, will allow refining these results and reveal the thermal properties and potential ice content of the southern regions in more detail.
Effects of Disc Insulator Type and Corona Ring on Electric Field and Voltage Distribution over 230-kV Insulator String by Numerical Method

Insulator strings with several material and profiles are very common in overhead transmission lines. However, the electric field and voltage distribution of insulator string is uneven which may easily lead to corona, insulators' surface deterioration and even flashover. So the calculation of the electric field and voltage distribution along them is a very important factor in the operation time. Besides, no remarkable endeavor regarding insulator material and profile and their impacts upon the electric field and voltage distribution has been made so far. In this paper several 230-kV insulator strings with different porcelain and glass units were simulated using 3-D FEM based software, and their electric fields and voltage distributions were calculated and compared together, to investigate the effect of insulator types on these quantities. Tower and conductors were included in all simulations and also the effect of corona ring on voltage and electric field distribution over insulator strings with different insulator types was investigated. Reported results show the dependency of voltage distribution to insulator material and profile.
Effects of local conspecific abundance on seed set and seed predation, and control of Carpinus laxiflora (Betulaceae) population density

Abstract In this study, the dependence of local conspecific abundance on seed set and predation was examined, and determinates of population density of the temperate tree species Carpinus laxiflora (Betulaceae) in Inagi city, Tokyo, Japan were identi -fied. During a good seed year (2013), seeds were sampled from 27 individuals and categorized as Sound, Empty, Predated, Immature, Decayed, or Broken. Empty seeds were identified as those that failed to fertilize and predation rates were defined as the proportion of seeds that were affected by predators. The proportion of the seed set that was fertilized was significantly positively correlated with local abundance of conspecific trees, while the proportion of seeds that escaped predation was significantly negatively correlated with local abundance of conspecific trees. Thereby, the production of Sound seeds was highest at sites with moderate local conspecific abundance. Although this phenomenon was only ob-served in a few cases, it clearly showed optimal reproductive success under conditions of moderate density of conspecific reproductive adults, suggesting a mechanism that controls the population density of this species.
Flyte of Odysseus: Allusion and the hoplōn krisis in Quintus Smyrnaeus Posthomerica 5

This article principally discusses the contest between Ajax and Odysseus in Quintus Smyrnaeus Posthomerica 5. Scholars have recently labelled the poem as a “Second Sophistic epic,” partly on the basis of discussion of the Hoplōn Krisis in Book 5. I begin by discussing the literary and cultural context of the Posthomerica, and especially the contest in Book 5, in relation to this label. I then show that the contest is closely modelled on speech-making situations in the Iliad, particularly contests of “flyting. ” I discuss the nature of flyting speeches, and discuss how Odysseus is made to appropriate Iliadic flyting settings to prove his worth as the rightful heir to the arms.
Competitiveness, Productivity and Economic Growth across the European Regions

Recent years have seen a surge of academic and policy attention devoted to thenotion of ‘competitiveness’: nations, regions and cities, we are told, have no option but tostrive to be competitive in order to survive in the new global marketplace and the ‘newcompetition’ (BEST, 1990, 1998) being forged by the new information or knowledge-driven economy. Policy-makers at all levels have been swept up in this competitivenessfever. Thus the importance of competitiveness has been a recurring theme in OECDassessments of the advanced economies. Similarly, the European Commission has becomemuch exercised by what it sees as the inferior competitiveness of the European Union, andhas set as one of its goals the catch-up of EU competitiveness with that of the US by 2010.Likewise, the UK government has placed the need to boost national competitiveness at thecentre of its policy agenda.This concern with competitiveness has quickly spread to regional, urban and localpolicy discourse. Growing interest has emerged in the ‘regional foundations’ of nationalcompetitiveness, and with developing new forms of regionally-based policy interventionsto help improve the competitiveness of every region and major city, and hence the nationaleconomy as a whole. In the UK, for example, the Government has assigned increasingimportance to the competitiveness of the country’s regions and cities as part of its re-orientation of national and regional policy (HM Treasury, 2001, 2002; DTI, 2001; ODPM,2002, 2003). In the EU, the issue of regional competitiveness has taken on particularsignificance not only in relation to its aim to close the ‘competitiveness gap’ with the US,but also as part of its pursuit of social and economic cohesion. Raising the competitivenessof Europe’s lagging and less prosperous regions is regarded as crucial to social cohesion,especially in the context of monetary union and EU enlargement. In fact, a still small butrapidly growing literature now exists on the topic of ‘territorial competitiveness’ (see, forexample,). However, this new focus on ‘place competitiveness’ raises a host of questions as towhat, precisely, is meant by the competitiveness of regions, cities and localities. In whatsense can one talk of regional competitiveness? In what sense do regions and cities
Cytological evidences of pollen abortion in Ornithogalum caudatum Ait

Ornithogalum caudatum Ait exhibits strong physiological adaptability; however, it suffers a serious menace of pollen abortion, as almost no seed is formed in the plants. In the current study, chromosome karyotype of root-tip cells (RTC) during mitosis, and chromosome behavior of pollen mother cells (PMC) during meiosis in O. caudatum were investigated. We recorded 18 euchromosomes with variable number (28~36) of B chromosomes in the somatic cells genome. In leptonema of meiotic prophase I, the synapsis between euchromosomes was normal, but there were several darker granular nodular bodies in the cells, which could be the precursor for B chromosomes. Some of the cells were observed as duplication loop in zygotene, indicating that the PMCs had gone through a chromosome structure variation with duplication, which could reduce the fertility of pollens. Numerous chromosome bridges, fragments and lagged chromosomes were observed in meiosis anaphase I. It reflects that these cells might have undergone paracentric inversion, which is one of the important reasons of pollen abortion. In meiosis anaphase II, the sister chromatids separate unusually forming the triad, which leads to gamete sterility. These findings conclude that pollen abortion in O. caudatum mainly results from the variation in chromosome structure, which could be related to the B chromosomes in somatic cells. Key words : Chromosome structure variation, B chromosome, root-tip cells, pollen mother cells, gamete sterility.
