Volunteer Work and Hedonic, Eudemonic, and Social Well-Being

Using two waves of panel data from the National Survey of Midlife in the United States (MIDUS), we examine the relationship between volunteer work and three dimensions of well-being: hedonic (e.g., positive mood), eudemonic (e.g., purpose in life), and social (e.g., feeling of belonging to the community). We test for the effects of volunteering measured as a binary and a continuous variable. Results show that volunteering enhances eudemonic and social well-being (but not hedonic well-being) although the number of hours contributed makes no difference. Conversely, people who have greater hedonic, eudemonic, and social well-being are more likely to volunteer and, in the case of hedonic and eudemonic well-being, volunteer more hours.
A role for sleep in brain plasticity

The idea that sleep might be involved in brain plasticity has been investigated for many years through a large number of animal and human studies, but evidence remains fragmentary. Large amounts of sleep in early life suggest that sleep may play a role in brain maturation. In particular, the influence of sleep in developing the visual system has been highlighted. The current data suggest that both Rapid Eye Movement (REM) and non-REM sleep states would be important for brain development. Such findings stress the need for optimal paediatric sleep management. In the adult brain, the role of sleep in learning and memory is emphasized by studies at behavioural, systems, cellular and molecular levels. First, sleep amounts are reported to increase following a learning task and sleep deprivation impairs task acquisition and consolidation. At the systems level, neurophysiological studies suggest possible mechanisms for the consolidation of memory traces. These imply both thalamocortical and hippocampo-neocortical networks. Similarly, neuroimaging techniques demonstrated the experience-dependent changes in cerebral activity during sleep. Finally, recent works show the modulation during sleep of cerebral protein synthesis and expression of genes involved in neuronal plasticity.
A Strategy for Comparing Alternative Software Development Life Cycle Models

It is difficult to compare and contrast models of software development because their proponents often use different terminology, and the models often have little in common except their beginnings (marked by a recognition that a problem exists) and ends (marked by the existence of a software solution). A framework is provided that can serve: as a basis for analyzing the similarities and differences among alternate life-cycle models; as a tool for software engineering researchers to help describe the probable impacts of a life-cycle mode; and as a means to help software practitioners decide on an appropriate life-cycle model to utilize on a particular project or in a particular application area. >
Moral Hazard in Sequential Teams

This paper considers a team in which production takes place sequentially and in which agents observe the actions taken by previous agents. We show that for such teams sharing rules exist which are balanced and induce e cient production as the unique equilibrium outcome. This in contrast to team structures studied by Holmstrom (1982) in which agents act simultaneously. The sharing rule which induces e cient production is simple, intuitive and robust to noise, sabotage, and collusive behavior. It induces e cient production even when agents obtain imperfect information about previous actions. JEL Classi cation: D82, L23
Charmonium at high temperature in two-flavor QCD

We compute charmonium spectral functions in 2-flavor QCD on anisotropic lattices using the maximum entropy method. Our results suggest that the S-waves ($J/\ensuremath{\psi}$ and ${\ensuremath{\eta}}_{c}$) survive up to temperatures close to $2{T}_{c}$, while the P-waves (${\ensuremath{\chi}}_{c0}$ and ${\ensuremath{\chi}}_{c1}$) melt away below $1.2{T}_{c}$.

Anti-Neutrophil Cytoplasmic Antibody in Behçet’s Disease

Anti neutrophil cytoplasmic antibody (ANCA) is strongly associated with some vasculitic disorders. Behçet’s disease (BD) is a systemic vasculitis of unknown etiology. In this study, ANCA was found to be positive in 8 out of 66 patients (10.2%) with BD by combination testing consisting of immunofluorescence and ELISA [one patient showed an atypical pattern by indirect immunofloresence techique, 6 patients were reactive to bacterial-permeability increasing protein (BPI) and one patient was reactive to Cathepsin G in ELISA]. There were no vascular manifestations such as veneous or arterial thrombosis and arterial aneurysms in ANCA-positive patients with BD. The results suggest that ANCA may be found in a minority of BD as those in previous published studies.
Characterizing and modeling the impact of wireless signal strength on smartphone battery drain

Despite the tremendous market penetration of smartphones, their utility has been and will remain severely limited by their battery life. A major source of smartphone battery drain is accessing the Internet over cellular or WiFi connection when running various apps and services. Despite much anecdotal evidence of smartphone users experiencing quicker battery drain in poor signal strength, there has been limited understanding of how often smartphone users experience poor signal strength and the quantitative impact of poor signal strength on the phone battery drain. The answers to such questions are essential for diagnosing and improving cellular network services and smartphone battery life and help to build more accurate online power models for smartphones, which are building blocks for energy profiling and optimization of smartphone apps. In this paper, we conduct the first measurement and modeling study of the impact of wireless signal strength on smartphone energy consumption. Our study makes four contributions. First, through analyzing traces collected on 3785 smartphones for at least one month, we show that poor signal strength of both 3G and WiFi is routinely experienced by smartphone users, both spatially and temporally. Second, we quantify the extra energy consumption on data transfer induced by poor wireless signal strength. Third, we develop a new power model for WiFi and 3G that incorporates the signal strength factor and significantly improves the modeling accuracy over the previous state of the art. Finally, we perform what-if analysis to quantify the potential energy savings from opportunistically delaying network traffic by exploring the dynamics of signal strength experienced by users.
Adjustment Difficulties of American Students in Israeli Institutions of Higher Learning.

The adjustment difficulties experienced by Americans who were studying in Israeli colleges, universities and yeshivot are identified. Implications for the orientation of such potential students are suggested. Many Jews from countries throughout the world and particularly the United States study in the State of Israel. Hochstein (1986) estimated that about 15,000 foreigners were students in Israeli colleges, universities and yeshivot and other formal educational programs in 1985. Of these, approximately one half were students from the United States. The number of American Jewish youth who pursue higher education in Israel is likely to grow in the future in that there is a growing feeling in the Jewish community in the United States that study in Israel should become an integral part of the education of American Jewish young people. Such experience would work toward fulfillment of the vision of the early twentieth century Jewish scholar Asher Ginsburg that Israel should be the "national spiritual center" of the Jewish people. Too, there is general agreement among international educators that more American students should spend some of their college years studying in a foreign country and in particular outside an Anglo-European setting (Council on International Exchange, 1981). While American students abroad share certain similarities with students from other countries, they are different in many important respects. For example, students from non-American countries study abroad to bring back new technology to their countries. In contrast, Americans go abroad largely for enrichment and to find a sense of purpose (Jenkins, et al, 1983). 1 2 In the context of this study, an important difference between American students in Israel and American students in other countries is that most who study in Israel are Jews (Ben Haim, 27 May 1991). They bring a prior emotional attachment to the host country, not usually found among other students sojourning in foreign lands. Because of the historical relationship which exists between the State of Israel and Jews everywhere, many of the visiting Jewish students do not see the State of Israel as foreign, nor themselves as foreigners in it. They expect to feel "at home" in what is considered a Jewish spiritual center and by some also a Jewish homeland. Herman (1970) referred to this, and several directors of various programs for foreign students in Israel confirmed it in personal interviews with the researchers (Cohen 1986; Horowitz 1986; Roe 1986, Pines 1986). This expectation would lead one to believe that American students in Israeli higher education would experience less adjustment difficulty than American students in other countries. PROBLEM The study reported herein was developed to determine the extent to which American students in Israeli colleges, universities and yeshivot experience adjustment difficulties in certain problem areas, as defined through the Study Abroad Adjustment Inventory, and to interpret the findings for their meaning to directors of foreign student programs in Israeli
Ovary Cells Apoptosis in Opium-Addicted Diabetic and Non-Diabetic Rats

Background Apoptosis is a physiological mechanism of cell death and it can be triggered by a variety of internal and external stimuli. It has been indicated that some opium derivatives develop cell apoptosis. Objectives The aim of this investigation was to evaluate the effect of opium addiction on ovary cell apoptosis in diabetic and non-diabetic Wistar rats. Materials and Methods This experimental study was done on control, control-addicted, diabetic and diabetic-addicted rats. DNA fragmentation as a biomarker of apoptosis was determined by the TUNEL assay. Results The blood glucose concentration in diabetic-addicted and diabetic rats was increased when compared to control (P < 0.001). There was no significant difference between weights of control, control-addicted (non-diabetic) and diabetic-addicted groups during this study. The results of this study indicated that apoptosis in addicted and diabetic-addicted ovary cells was significantly higher than in diabetic group, and also apoptosis in addicted group was significantly more than the control rats. In addition, we found that ovary cells apoptosis of diabetic rats were significantly less than in control group. Conclusions Overall, these findings suggest that opium-addiction could play an important role in ovary cell apoptosis and could be very harmful for the reproductive system. Also, ovary cells of non-diabetic rats are more susceptible to opium-induced apoptosis than those of diabetic.
Endodontic Treatment of a Double-Rooted Maxillary Second Molar with Four Canals: A Case Report

A healthy female was referred to Endodontic Department. The referral letter from her dentist expressed that an emergency pulpotomy of tooth #27 had been carried out with probable perforation of the chamber floor which was due to the unusual anatomy of the chamber. Cone-beam computed tomography (CBCT) revealed that the tooth had two mesial and two distal canals. Perforation site was repaired and endodontic treatment was completed. At 24-month follow-up, patient was asymptomatic and clinical and radiographic examinations showed successful outcomes.
Tidal interactions of close-in extrasolar planets: The OGLE cases

Close-in extrasolar planets experience extreme tidal interactions with their host stars. This may lead to a reduction of the planetary radius and a spin-up of stellar rotation. Tidal interactions have been computed for a number of extrasolar planets in circular orbits within 0.06 AU, namely for OGLE-TR-56 b. We compare our range of the tidal dissipation value with two dissipation models from Sasselov (2003) and conclude that our choices are equivalent to these models. However, applied to the planet OGLE-TR-56 b, we find in contrast to Sasselov (2003) that this planet will spiral-in toward the host star in a few billion years. We show that the average and maximum value of our range of dissipation are equivalent to the linear and quadratic dissipation models of Sasselov (2003). Due to limitations in the observational techniques, we do not see a possibility to distinguish between the two dissipation models as outlined by Sasselov (2003). OGLE-TR-56 b may therefore not be well suited to serve as a test case for dissipation models. The probable existence of OGLE-TR-3 b at 0.02 AU and the discovery of OGLE-TR-113 b at 0.023 AU and OGLE-TR-132 b at 0.03 AU may also counter Sasselovs (2003) assumption of a pile-up stopping boundary at 0.04 AU.
Rate-Maximization Channel Assignment Scheme for Cognitive Radio Networks

In this paper, we consider the coordinated spectrum access problem in a multiuser single-transceiver cognitive radio network (CRN). Our objective is to maximize the sum-rate achieved by all contending cognitive radio users with respect to both spectrum assignment and transmission rate. The problem is posed as a rate-maximization problem subject to hardware and interference constraints. Specifically, we show that this problem can be formulated as an integer linear programming problem (ILP) with unimodular constraint matrix, which can be optimally solved in polynomial time using linear programming. Unlike previous research, our formulation is not restricted to the information-theoretic capacity, and can be applied to any arbitrarily given rate-SINR function. We also develop a distributed CSMA/CA-based MAC protocol for CRNs to realize the optimal assignment in a distributed manner. Simulation results indicate that compared to a reference CSMA/CA CRN MAC protocol, the proposed protocol significantly improves network throughput and preserves fairness.
Online Education in Public Affairs

This exploratory study provides an overview of the current landscape of online education in the fields of Master of Public Administration and Master of Public Policy (MPA/MPP) utilizing a dataset compiled from content analysis of MPA/MPP programs’ websites and survey of 96 National Association of Schools of Public Affairs and Administration (NASPAA) affiliated institutions. Areas studied include the rationales for offering or not offering online education, concerns with technology, modes of online instruction, student services, faculty and staff demands and enrollment patterns. The primary goal stated for offering courses and degrees online is to reach more students. We found substantial diversity in teaching methods which suggests students and instructors alike are attracted to online education due to its flexibility. Surprisingly, we did not find any significant problems with technological concerns.
The Lipid Droplet Protein Hypoxia-inducible Gene 2 Promotes Hepatic Triglyceride Deposition by Inhibiting Lipolysis*

Background: Excess hepatic triglyceride accumulation is associated with metabolic disease. Results: Hig2 localizes to hepatic lipid droplets, enhancing their lipid content, and its deficiency increases triglyceride lipolysis. Conclusion: Hig2 is a lipid droplet protein in hepatocytes that promotes liver triglyceride deposition by reducing its rate of degradation. Significance: Hig2 is revealed as a critical lipid droplet protein controlling liver fat. The liver is a major site of glucose, fatty acid, and triglyceride (TG) synthesis and serves as a major regulator of whole body nutrient homeostasis. Chronic exposure of humans or rodents to high-calorie diets promotes non-alcoholic fatty liver disease, characterized by neutral lipid accumulation in lipid droplets (LD) of hepatocytes. Here we show that the LD protein hypoxia-inducible gene 2 (Hig2/Hilpda) functions to enhance lipid accumulation in hepatocytes by attenuating TG hydrolysis. Hig2 expression increased in livers of mice on a high-fat diet and during fasting, two states associated with enhanced hepatic TG content. Hig2 expressed in primary mouse hepatocytes localized to LDs and promoted LD TG deposition in the presence of oleate. Conversely, tamoxifen-inducible Hig2 deletion reduced both TG content and LD size in primary hepatocytes from mice harboring floxed alleles of Hig2 and a cre/ERT2 transgene controlled by the ubiquitin C promoter. Hepatic TG was also decreased by liver-specific deletion of Hig2 in mice with floxed Hig2 expressing cre controlled by the albumin promoter. Importantly, we demonstrate that Hig2-deficient hepatocytes exhibit increased TG lipolysis, TG turnover, and fatty acid oxidation as compared with controls. Interestingly, mice with liver-specific Hig2 deletion also display improved glucose tolerance. Taken together, these data indicate that Hig2 plays a major role in promoting lipid sequestration within LDs in mouse hepatocytes through a mechanism that impairs TG degradation.
Heart rate variability and heart rate turbulence in patients with chronic obstructive pulmonary disease.

BACKGROUND In chronic obstructive pulmonary disease (COPD) patients, functional and structural changes of the respiratory system greatly influence cardiovascular autonomic functions. Determining autonomic balance may be important in understanding the pathophysiology of COPD and useful clinically in the treatment of COPD patients. Heart rate variability (HRV) and heart rate turbulence (HRT) are useful tools in assessing the autonomic neurovegetative function. Our aim in this study was to evaluate the HRV and HRT variables in COPD patients. Twenty five moderate to severe COPD patients and 25 healthy subjects were included in this study. METHODS Pulmonary function tests and echocardiographic examination, arterial blood gases analysis were performed, HRV and HRT analysis were assessed from a 24-hour Holter recording. RESULTS When HRV and HRT parameters were compared, COPD patients had significantly decreased sNN50 total, pNN50, SDANN, SDNN, SDNNI, rMSDD in time domain HRV parameters, and the values of the HRT onset was significantly less negative in COPD patients. Although the values of the HRT slope were lower in COPD patients, there was no significant difference between the two groups. We also found a correlation between HRT and HRV parameters. CONCLUSIONS In addition to HRV parameters, HRT onset was significantly different in COPD patients. In our opinion, the combination of HRV variables and HRT onset may be simple and elegant ways of evaluating cardiac autonomic functions. New investigations of HRT and HRV in COPD patients have a potential importance for improving risk stratification and therapeutic approaches, and understanding the autonomic outcomes of the disease process.
ACADEMIC SELF-EFFICACY, ATTITUDES AND KNOWLEDGE AMONG UNDERGRADUATE BIOSTATISTICS STUDENTS

Objective: The objectives of the present study were to evaluate the academic self-efficacy, content knowledge and confidence in these responses, as well as attitudes of students in an undergraduate biostatistics course. Design: The study was a cross-sectional analytical design. Setting: The study was carried out in Masinde Muliro University of science and technology Sample: Sampling frame consisting of 114 students who had at least taken a biostatistics course. Probability sampling technique of purposive sampling method was applied to select the students. ( n = 114 ) Analysis: Data were analyzed through path analysis and confirmatory factor analysis. Main measures: Self-efficacy, confidence, attitude and knowledge Results: The estimation of this hypothesized structural model yielded an acceptable fit to the data, χ2 =45.9, df = 2; χ 2 /df ratio =22.123 (good), CFI = . 933; RMSEA = . 071, with 90% C.I. = . 044 - . 083, SRMR = . 078. Attitude was a direct predictor of self-efficacy (β = .490, p < .001), confidence was a direct predictor of self-efficacy (β = .400, p < .001), self-efficacy was a direct predictor of knowledge (β = .515, p < .001). Conclusion: The study concludes that academic self-efficacy and optimism were strongly related to performance. Therefore, this study supports previous literature that found academic self-efficacy affects the success of students in the sciences. Recommendation: Educators should be aware of students' personality antecedents in order to improve their students' beliefs about their capabilities to master different areas of coursework.

Binding Energy and the Fundamental Plane of Globular Clusters

This paper develops a physical description of the fundamental plane of Galactic globular clusters that explains all empirical trends and correlations in a large number of cluster observables and provides a small but complete set of truly independent constraints on theories of cluster formation and evolution in the Milky Way. In a very good first approximation, the internal structures and dynamics of Galactic globulars are described by single-mass, isotropic King models and are thus characterized by four nominally independent physical parameters. Within this theoretical framework, it is shown that (1) 39 regular (non-core-collapsed) globulars with measured central velocity dispersions all share a common core mass-to-light ratio, ϒV,0 = 1.45 M☉ L, and (2) 109 regular globulars both with and without direct observations of ϒV,0 show a very strong correlation between global binding energy and total luminosity, regulated by Galactocentric position: Eb = 7.2 × 1039 ergs(L/L☉)2.05(rgc/8 kpc)-0.4. The observational scatter about either of these two constraints can be attributed fully to random measurement errors, making them the defining equations of a fundamental plane (FP) to which real clusters are confined in the larger, four-dimensional parameter space of general King models. They are shown to underlie a pair of bivariate correlations first found, and used to argue for the existence of a globular cluster FP, by Djorgovski. A third, weaker correlation, between clusters' total luminosities and King-model concentration parameters, is related to the (nonrandom) distribution of globulars on the FP. With L, ϒV,0, Eb, and the central concentration c thus chosen as the four physical quantities that define any single globular cluster, the FP equations for ϒV,0 and Eb(L,rgc) are used to derive expressions for any other observable in terms of only L, rgc, and c. Results are obtained for generic King models and applied specifically to the globular cluster system of the Milky Way.
