Is procrastination related to sleep quality? Testing an application of the procrastination–health model

Abstract Despite a growing body of research on the consequences of procrastination for health and well-being, there is little research focused on testing or explaining the potential links between procrastination and sleep quality. Using the procrastination–health model as our guiding conceptual lens, we addressed this gap by examining how and why trait procrastination may be linked to various dimensions of sleep quality across two student samples. In Study 1, procrastination was associated with feeling unrested, but not with sleep disturbance frequency, in a sample of Greek undergraduate students (N = 141). In Study 2, bootstrapping analysis of the indirect effects of procrastination on an index of sleep quality through perceived stress in a sample of Canadian students (N = 339) was significant, supporting an extended procrastination–health model view of how chronic self-regulation failure may compromise sleep quality. Given the potential for dynamic and reciprocal relations among procrastination, stress, and sleep quality, suggested by the current and other research, the ways in which procrastination may contribute to and be influenced by poor sleep quality warrant further investigation.
Capital account reform and short- and long-run stock price leadership

This paper studies the effect of capital account liberalization policies on the price discovery of cross-listings in Chinese stocks. We construct a non-linear causality framework that decomposes short- and long-run dimensions of price leadership. Our analysis shows that capital account liberalization has had a profound effect on long-run A- and H-price leadership traits. Specifically, increased inward capital movement from Qualified Foreign Institutional Investors strengthens long-term leadership in the mainland A-market. Similarly, increased capital outflow from the Chinese mainland galvanizes long-term price discovery processes in the Hong Kong H-market. We thus offer strong evidence that capital account liberalization promotes stock market efficiency in the long-run. The present study's empirical account also suggests that such capital flows inhibit short-term lead-lag effects.
Platelet Activation as a Possible Indicator of Disease Activity in Chronic Urticaria: Link with Blood Coagulation and Mast Cell Degranulation

Background: Much attention has been paid to activation of the blood coagulation cascade during urticaria attacks. Elevated levels of plasma D-dimer and prothrombin fragment 1+2 have been reported. The final product of the coagulation cascade, thrombin, may induce mast cell degranulation, complement fragmentation, or platelet-activating factor expression. However, the involvement of platelets in urticaria is poorly understood. Methods: We examined the relationship between disease activity and plasma levels of platelet factor IV, β-thromboglobulin, D-dimer, and prothrombinfragment (Fr) 1+2 in 23 patients with chronic urticaria. Results: We observed elevated plasma levels of platelet factor IV (13/23) and β-thromboglobulin (15/23) in patients with chronic urticaria that returned to normal after anti-histamine therapy. Platelet re-activation was observed in recurrent urticaria. Some cases showed clinical response to anti-platelet therapy or Helicobacter pylori decolonization in combination with anti-histamine treatment. Conclusions: Platelet activation is a possible indicator of disease activity in chronic urticaria. Platelet-derived factors with or without blood coagulation products might induce mast cell degranulation in chronic urticaria.
Stability Analysis of State Saturation 2D Discrete Time-Delay Systems Based on F-M Model

The problem of stability analysis is investigated for a class of state saturation two-dimensional (2D) discrete time-delay systems described by the Fornasini-Marchesini (F-M) model. The delay is allowed to be a bounded time-varying function. By constructing the delay-dependent 2D discrete Lyapunov functional and introducing a nonnegative scalar , a sufficient condition is proposed to guarantee the global asymptotic stability of the addressed systems. Subsequently, the criterion is converted into the linear matrix inequalities (LMIs) which can be easily tested by using the standard numerical software. Finally, two numerical examples are given to show the effectiveness of the proposed stability criterion.
Correlation between visual acuity, external limiting membrane and photoreceptor status in patients with neovascular age related macular degeneration treated with bevacizumab

Introduction/Objectives: To investigate the correlation between best-corrected visual acuity (BCVA), the foveal photoreceptor-inner segment/outer segment (IS/OS) junction and external limiting membrane (ELM) in patients with neovascular age-related macular degeneration (NVAMD) after the treatment with bevacizumab, as well as the correlation between the above-mentioned parameters and different types of neovascular membrane, classified by fluorescein angiography (FA). Methods: We present 82 patients with NVAMD, treated with intravitreal bevacizumab. All patients underwent a basic ophthalmological examination, FA and optical coherence tomography (OCT). Based on the results of fluorescein angiography, all the patients were divided into two main groups - type I and type II of choroidal neovascular membrane (CNV). The OCT images revealed either the presence or the absence of IS/OS and ELM. Results: After the treatment, the mean best corrected visual acuity improved significantly in both groups (p<0.01). Preserved IS/OS and ELM were registered in a smaller number of patients as compared to the situation before the treatment (p<0.01). After the treatment, the mean BCVA was significantly better in patients with preserved IS/OS and ELM (p<0.01). In addition, we registered a higher number of patients with preserved ELM in the first group than in the second group (p<0.01), whereas there was no significant difference in the integrity of IS/OS between the groups (p>0.05). Conclusion: The patients with preserved IS/OS and ELM achieved better final visual acuity as compared to the patients without preserved IS/OS and ELM. In our patients, the absence of IS/OS and ELM were more frequent in type II (classic and predominantly classic) CNV than the type I (occult and minimally classic) CNV.
Attributional tendencies in cultural explanations of M&A performance

This paper focuses on managers' attributions of M&A performance. Our analysis indicates that there is a linear association between performance and attributions to cultural differences, which is moderated by prior experience. Furthermore, our results suggest that there is a curvilinear association between performance and attributions to managers' actions, but we found no support for the moderating effect of experience for this association. By substantiating these attributional tendencies, our results contribute to research on M&As and studies on attribution more generally. In particular, our study helps to put cultural differences in perspective and cautions researchers and practitioners alike to avoid simplistic explanations of M&A performance.
Classroom Management and Students' Self-Esteem: Creating Positive Classrooms.

Middle school students experience substantial changes in their emotion and cognition while they grow. They have mixed feelings, which may negatively affect their motivation, self-esteem, and academic success due to different classroom management strategies of their teachers. There is available research about motivation of middle school students and classroom management approaches of middle school teachers. However, empirical studies are lacking to provide sufficient information about the relationship between student self-esteem and classroom management in middle schools. In this study, classroom management of middle school teachers and self-esteem of middle school students were examined. A total of eight middle school teachers and 60 middle school students from an urban middle school in western United States participated in the study. Data acquired from the Classroom Management Self – Assessment (CMSA) and the Coopersmith Self-Esteem Inventory (CSEI) were analyzed with independent samples t-tests. The findings of the study indicated a significant difference between teachers on CMSA and between students on CSEI. Key words: Classroom management, student self-esteem, teachers, middle school.
Effect of Y on the Properties of Sm-Doped Ceria for IT-SOFC Applications

The co-doped ceria-based materials with general composition formula Ce0.8-xYxSm0.2O2-δ (x = 0, 0.02, 0.04, 0.06) were prepared through the sol-gel method. The single phase of the prepared materials was confirmed by X-ray diffraction (XRD). The lattice parameters were determined by least square fitting of UNIT CELL programme. The linear variation of lattice parameter with concentration of Y into the samarium doped ceria (SDC) indicates the validity of Vegard’s law. The crystallite size of the samples obtained by using of Scherrer formula is in the range from 34 nm to 49 nm. The thermal expansion studies were carried out by using dilatometric technique in the temperature range from room temperature to 1000°C. It was observed that the thermal expansion increased linearly with increasing temperature for all the samples. The electrical conductivity was studied using impedance spectroscopy. It was observed that the composition Ce0.74Y0.06Sm0.2O2-δ showed higher electrical conductivity and lower activation energy (≈1.05 eV) than other compositions in the present investigation. This composition is thus a possible candidate for use the electrolyte in intermediate temperature solid oxide fuel cells (IT-SOFC).
Physical regimes for feedback in galaxy formation

We present a new (semi-)analytical model for feedback in galaxy formation. The interstellar medium (ISM) is modelled as a two-phase medium in pressure equilibrium, where the cold phase is fragmented into clouds with a given mass spectrum. Cold gas infalls from an external halo. Large clouds are continually formed by coagulation and destroyed by gravitational collapse. Stars form in the collapsing clouds; the remnants of exploding Type II supernovae (SNe) percolate into a single super-bubble (SB) that sweeps the ISM, heating the hot phase (if the SB is adiabatic) or cooling it (in the snowplough stage, when the interior gas of the SB has cooled). Different feedback regimes are obtained whenever SBs are stopped either in the adiabatic or in the snowplough stage, either by pressure confinement or by blowout. The resulting feedback regimes occur in well-defined regions of the space defined by vertical scalelength and surface density of the structure. In the adiabatic blowout regime, the efficiency of SNe in heating the ISM is rather low (∼5 per cent, with ∼80 per cent of the energy budget injected into the external halo), and the outcoming ISM is self-regulated to a state that, in conditions typical of our galaxy, is similar to that found in the Milky Way. Feedback is most efficient in the adiabatic confinement regime, where star formation is hampered by the very high thermal pressure and the resulting inefficient coagulation. In some significant regions of the parameter space, confinement takes place in the snowplough stage; in this case, the hot phase has a lower temperature and star formation is quicker. In some critical cases, found at different densities in several regions of the parameter space, the hot phase is strongly depleted and the cold phase percolates the whole volume, giving rise to a burst of star formation. While the hot phase is allowed to leak out of the star-forming region, and may give rise to a tenuous wind that escapes the potential well of a small galactic halo, strong galactic winds are predicted to occur only in critical cases or in the snowplough confinement regime whenever the SBs are able to percolate the volume. This model provides a starting point for constructing a realistic grid of feedback solutions to be used in galaxy formation codes, either semi-analytical or numerical. The predictive power of this model extends to many properties of the ISM, so that most parameters can be constrained by reproducing the main properties of the Milky Way.
Selection of the most adequate suspension system for lower limb amputees: evaluation parameters

A proper suspension system influence the overall satisfaction of a lower limb ¬amputee on the daily basis. The present study aimed to establish the main parameters needed to evaluate and support the advantages of the new proposed suspension system by reviewing the literature related with amputee’s satisfaction. Eleven studies were select and detailed analyzed. Most of the mentioned studies used Prosthesis Evaluation Questionnaire (PEQ) as a method to classify the amputee’s satisfaction in different domains. Several studies pointed out pistoning and easy donning and doffing as the main parameters that addresses the amputee’s satisfaction with the currently available suspension systems. Amputees had a general preference for suspension systems that have an easy donning and doffing. However, the current studies do not explore the impact of the amputee’s characteristics on their satisfaction with the suspension system. The authors believe that amputee’s characteristics such as age, activity level, duration of prosthetic use, skin quality of the residual limb and hand functionality can influence the selection of the suspension system. Further research is still needed to objectively define the clinical parameters for the selection of the most adequate suspension system. Therefore the research should be carried out using a homogenous study group to perceive the advantages, drawbacks and problems using different suspension systems and, consequently, to understand the full potential of the suspension system proposed by the authors.
BACTERIAL ANTAGONISTS FROM USED ROCKWOOL SOILLESS SUBSTRATES SUPPRESS FUSARIUM WILT OF TOMATO

Five bacterial strains (FC-6B, FC-7B, FC-8B, FC-9B and FC-24B) isolated from used rockwool soilless substrates were identified using 16S ribosomal DNA (16S rDNA) sequence analysis as belonging to the Pseudomonas genus. Seven glasshouse trials were conducted in order to evaluate the efficacy of these bacteria strains (Pseudomonas putida FC-6B, Pseudomonas sp. FC-7B, Pseudomonas putida FC-8B, Pseudomonas sp. FC-9B and Pseudomonas sp. FC-24B) together with Achromobacter sp. AM1 and Serratia sp. DM1 obtained from suppressive soil, against Fusarium wilt of tomato. Two commercial bioproducts, Trichoderma harzianum T22 (RootShield) and Pseudomonas chlororaphis MA 342 (Cedomon) were also evaluated. Different treatment strategies including soil application (107 and 108 cfu ml-1) were adopted in different glasshouse trials (Trial I to VI) to test the efficacy of the bacterial strains against Fusarium wilt. Root dipping was used in Trial VII (108 and 109 cfu ml-1). The lowest disease incidence (3.3) was recorded with a single application of P. putida FC-6B at 108 cfu ml-1. Similar results were obtained with the same bacteria when the concentration was decreased to 107 cfu ml-1 but an increasing number of applications was required. The highest plant biomass (50.3 g/plant) was recorded in the P. putida FC-8B treatment (Trial III). In conclusion, the current study showed the potential biocontrol activity of bacterial strains FC-6B, FC-7B, FC-8B, FC-9B and FC-24B isolated from re-used rockwool soilless substrates against Fusarium wilt disease, and the growth promoting activity of these strains on tomato plants.
Genetic signature of the colonisation dynamics along a coastal expansion front in the damselfly Coenagrion scitulum

1. Many insects are expanding their distribution range polewards as a result of climate change, which has been shown to be associated with founder effects leading to a reduction in genetic diversity and an increase in genetic differentiation. These spatial genetic patterns may arise from colonisation from a broad expansion front or a limited neighbourhood after a stepping stone model of dispersal. The temporal persistence of such founder effects are poorly understood, mainly because studies looking at the fine-scale initial temporal dynamics of the genetic signature of a range expansion are rare. 2. Using microsatellite markers, we performed a detailed spatiotemporal genetic analysis of the range expanding damselfly Coenagrion scitulum (Rambur) along a coastal axis during the first years after colonisation. 3. A decrease was in (private) allelic richness when going northwards along the coastline, which is consistent with a scenario of cumulative founder events. In spite of the spatiotemporal dynamics in the observation records of the species along the coastline, the spatial genetic data indicated a major contribution from the broad expansion front during the colonisation of the coastline rather than a stepping-stone colonisation process. 4. The fine-scale temporal dynamics of the range expansion indicated the absence of persistent founder effects and instead showed considerable temporal instability in genetic indices at the more northern edge populations. This may be explained by genetic immigration and admixture from the broad expansion front in this active disperser.
Characterization of nucleation during laboratory earthquakes

We observe the nucleation phase of in‐plane ruptures in the laboratory. We show that the nucleation is composed of two distinct phases, a quasi‐static and an acceleration stage, followed by dynamic propagation. We propose an empirical model which describes the rupture length evolution: The quasi‐static phase is described by an exponential growth while the acceleration phase is described by an inverse power law of time. The transition from quasi‐static to accelerating rupture is related to the critical nucleation length, which scales inversely with normal stress in accordance with theoretical predictions, and to a critical surfacic power, which may be an intrinsic property of the interface. Finally, we discuss these results in the frame of previous studies and propose a scaling up to natural earthquake dimensions.
The Effect of Entrepreneurial Leadership, Self-Efficacy and Organizational Performance: A Conceptual Paper

Entrepreneurship education programs are proliferating in universities and colleges in the country due to the importance and increasing acceptance of entrepreneurship. However, one may argue the purpose of having entrepreneurship education to those who are not interested in starting a business. What do entrepreneurship subjects contribute towards students generally? The purpose of entrepreneurship education is not only to nurture entrepreneurs, but to inculcate entrepreneurial orientation and characteristics to the students. Therefore, this study investigates how entrepreneurial orientation that has been gained by students in entrepreneurship subjects, influence their academic grades. So far, there is lack of empirical study on this matter creating a literature gap. The study is done at Universiti Teknologi MARA, Malaysia. The result shows that three elements of entrepreneurial orientation (risk-taking, proactiveness and competitive aggressiveness) positively influence academic grades while the remaining elements of entrepreneurial orientation (autonomy and innovativeness) do not influence academic grades.
Preliminary phytochemical screening and antimicrobial activity of Samanea saman

Samanea saman is a tropically distributed medicinal plant. Antimicrobial activity of aqueous extract of this plant was investigated by Well-diffusion method against three organisms: Escherichia coli, Staphylococcus aureus and Candida albicans. The plant extract showed inhibitory activity against all the tested organisms. Five mg/ml inhibited the growth of E. coli but slightly higher concentration of 10 mg/mL was necessary to show inhibition against S. aureus and C. albicans. Phytochemical screening of the plant revealed the presence of tannins, flavonoides, saponins, steroids, cardiac glycosides and terpenoids. The study scientifically validates the use of plant in traditional medicine. Key words: Samanea saman, Escherichia coli, Staphylococcus aureus,saponins, tannins, alkaloids, glycosides and flavonoides.
Thermal modelling of water activity on comet 67P/Churyumov-Gerasimenko with global dust mantle and plural dust-to-ice ratio

We perform a thermo-physical analysis on water activity of comet 67P/Churyumov-Gerasimenko (67P). The sublimation of water is assumed to occur from beneath a global, desiccated dust mantle over the irregular-shaped nucleus. The concept of two thermal models, the recipe of model formulation and the strategy of application to comet 67P are described. For an accurate and efficient evaluation of energy input by insolation and self-heating over the nucleus, a Landscape data base is devised based on polyhedral shape models of the nucleus. We apply the thermal models to investigate the impact of certain parameters of nucleus properties on water production. It is found that the measured water production of 67P can be overall attributed to sublimation of water ice with a mass abundance of a few to 10 per cent beneath a uniform dust mantle of several millimetres to one centimetre in thickness. Insofar as 67P is concerned, we argue against the necessity to invoke assumptions on localized water activity, or on the distinction of active/dormant surface areas.
Repayment in microfinance: The Role of financial literacy and caste

We evaluate the impact of a mandatory lnancial education program on female customers of an urban micro-lnance institution (MFI) headquartered in Mumbai, India. We exploit the variation in timing of the lnancial literacy program across the branches to identify if there was an improvement in the loan repayment performance. Our results suggest that lnancial literacy led to a decline in the total number of days taken to make loan repayments as well as the number of months in which the repayment was late. More importantly, lnancial education helped those in homogeneous groups of reserved castes overcome their initial disadvantage of low lnancial literacy relative to those in mixed caste groups.
Preferences for inequality: East vs. West

Do preferences for income inequality differ systematically between the post-socialist countries of Central and Eastern Europe and the Western established market economies? This paper analyses 1999 data from a large international survey to address this question. In particular, we examine whether attitudes to inequality differ between East and West even after the 'conventional' determinants of attitudes are controlled for. Results suggest that this is indeed the case. A decade after the breakdown of communism, people in transition countries are indeed significantly more 'egalitarian' than those living in the West, in the sense that they are less willing to tolerate existing income inequalities, even after the actual level of income inequality and other determinants of attitudes are taken into account.
