Time Deficits with Children: The Link to Parents’ Mental and Physical Health

Time spent with children has become a central concern in North American parenting culture. Using the 2011 Canadian Work, Stress, and Health Study (n = 2,007), the authors examine employed parents’ perceptions about having too little time with children and whether these relate to parents’ mental and physical health. The “pernicious stressor” hypothesis posits that the demands of paid work combined with intensive mothering or involved fathering create unique time tensions that act as chronic stressors and that these are associated with poorer health and well-being. Alternatively, the “public face” hypothesis suggests that parents often present themselves as good mothers or fathers through an expressed lack of time with children, but statements are superficial and thus are not related to health. The authors find that about half of employed parents report time shortfalls with children; work hours, schedule control, location of work, and family context are related to perceived time deficits with children. Supporting the pernicious stressor hypothesis, expressed time deficits are associated with distress, anger, and sleep problems, even when adjusting for work and family factors.
The Effects of NBPTS-Certified Teachers on Student Achievement. Working Paper 4.

In this study, we consider the efficacy of a relatively new and widely accepted certification system for teachers established by the National Board for Professional Teaching Standards (NBPTS). We utilize an extensive database covering the universe of teachers and students in Florida for a four-year span to determine the relationship between NBPTS certification and the impact of teachers on student test scores from both low-stakes and high-stakes exams. Contrary to some previous studies, we find evidence that NBPTS certification provides a positive signal of a teacher's contribution to student achievement only in a few isolated cases. However, our results do reinforce evidence from previous research that the process of becoming NBPTS certified does not increase teacher productivity. © 2009 by the Association for Public Policy Analysis and Management.

Spontaneous Behavior in Noise and Silence: A Possible New Measure to Assess Tinnitus in Guinea Pigs

This study describes two experiments that were conducted in search for a behavioral paradigm to test for tinnitus in guinea pigs. Conditioning paradigms are available to determine the presence of tinnitus in animals and are based on the assumption that tinnitus impairs their ability to detect silent intervals in continuous noise. Guinea pigs have not been subjected to these paradigms yet; therefore, we investigated whether guinea pigs could be conditioned in the two-way shuttle-box paradigm to respond to silent intervals in noise. Even though guinea pigs could be trained relatively easy to respond to the presence of a noise interval, training guinea pigs to silent intervals in noise was unsuccessful. Instead, it appeared that they became immobile when the continuous stimulus was suddenly stopped. This was confirmed by the next experiment, in which we subjected guinea pigs to alternating intervals of noise and silence with a random duration between 30 and 120 s. Indeed, guinea pigs were significantly longer immobile during silence compared to during noise. By interpreting immobility as a signature of perceiving silence, we hypothesized that the presence of tinnitus would reduce immobility in silence. Therefore, we unilaterally exposed one group of guinea pigs to an 11-kHz tone of 124 dB sound pressure level for 1 h. A subset of the exposed animals was significantly more active in silence, but also more active in noise, as compared to the control group. The increased mobility during silent intervals might represent tinnitus. However, the increased mobility in noise of this group implies that the observed behavior could have derived from, e.g., an overall increase in activity. Therefore, conducting validation experiments is very important before implementing this method as a new screening tool for tinnitus. Follow-up experiments are discussed to further elucidate the origin of the increased mobility in both silence and noise.
Foundational aspects of nonlocality

Nonlocality refers to correlations between spatially separated parties that are stronger than those explained by the existence of local hidden variables. Quantum mechanics is known to allow some nonlocal correlations between particles in a phenomena known as entanglement. We explore several aspects of nonlocality in general and how they relate to quantum mechanics. First, we construct a hierarchy of theories with nonlocal correlations stronger than those allowed in quantum mechanics and derive several results about these theories. We show that these theories include codes that can store an amount of information exponential in the number of physical bits used. We use this result to demonstrate an unphysical consequence of theories with stronger-than-quantum correlations: learning even an approximate description of states in such theories would be practically impossible. Next, we consider the difficult problem of determining whether specific correlations are nonlocal. We present a novel learning algorithm and show that it provides an outer bound on the set of local states, and can therefore be used to identify some nonlocal states. Finally, we put nonlocal correlations to work by showing that the entanglement present in the vacuum of a quantum field can be used to detect spacetime curvature. We quantify how the entangling power of the quantum field varies as a function of spacetime curvature.
A new polar sphere decoding technique for Phase-Shift Based Layered Linear Space-Time Codes

In this paper, a modified algorithm based on polar sphere decoding is introduced for phase-shift based layered linear space-time codes (PSBLLSTC) that are very efficient in terms of performance and data rate. This method simplifies the decoding process and provides the possibility of using sphere decoding in the cases with non-lattice configuration while the complexity of decoding would reduce significantly in comparison with maximum likelihood decoding without loss of reliability. In this work, examples of BPSK and QPSK along with the numerical results of complexity reduction is presented. The proposed algorithm solves the problem of highly complicated decoding of PSBLLSTCs and makes them utilizable in practical cases.
Responsabilidad social, necesidades psicológicas básicas, motivación intrínseca y metas de amistad en educación física (Social responsibility, basic psychological needs, intrinsic motivation, and friendship goals in physical education)

El objetivo de este estudio fue analizar la capacidad de prediccion de la responsabilidad social, las necesidades psicologicas basicas y la motivacion sobre la meta de aproximacion a la amistad a partir de la Teoria de la Autodeterminacion. Una muestra de 402 estudiantes (209 mujeres y 193 hombres; M = 14.20; DT = 1.52) de entre 12 y 18 anos, procedentes de tres centros de educacion secundaria del norte de Espana cumplimentaron un cuestionario que incluia la subescala de responsabilidad social del Cuestionario de la Responsabilidad Personal y Social (PSQR), la Escala de Necesidades Psicologicas Basicas en Educacion Fisica (BPN-PE), la subescala de motivacion intrinseca de la Escala del Locus Percibido de Casualidad (PLOC) y la subescala de aproximacion-amistad del Cuestionario de Metas de Amistad (FGQ-PE). Los resultados del analisis de regresion lineal multiple reflejaron que la responsabilidad social, las necesidades psicologicas basicas de relacion y autonomia y la motivacion intrinseca predecian significativamente la meta de aproximacion-amistad. Estos resultados reflejan la importancia de crear contextos educativos en los que se potencie la responsabilidad social, las relaciones, la autonomia y la motivacion intrinseca de los estudiantes con el objetivo de mejorar sus metas de amistad. Abstract. The goal of the present study was to assess social responsibility, basic psychological needs, and motivation towards friendship-approach goals within the Self-Determination Theory. A total of 404 students from three secondary schools of northern Spain (209 females and 193 males; M = 14.20; DT = 1.52), aged from 12 to 18 years, completed a questionnaire that included the social responsibility subscale of the Personal and Social Responsibility Questionnaire (PSQR), the Basic Psychological Needs in Physical Education Scale (BPN-PE), the subscale of intrinsic motivation of the Perceived Locus of Causality (PLOC), and the subscale of friendship-approach of the Friendship Goals Questionnaire in Physical Education (FGQ-PE). Results of multiple linear regression analysis showed that social responsibility, relatedness and autonomy, and intrinsic motivation significantly predicted friendship-approach goals. These results suggest the importance of creating educational contexts that can foster social responsibility, relatedness, autonomy, as well as students’ intrinsic motivation, with the aim to improve their friendship goals.
Strategic Communication and Emergence: A Dual Narrative Framework

ABSTRACT The idea that strategic communication is not only planned, but also emergent, has gained increasing attention in the field of strategic communication research. However, embracing the idea of emergence comes with several definitional, methodological, and programmatic challenges. This article responds to these challenges by proposing a dual narrative framework of strategic communication. The framework introduces an approach that explains both practice (strategizing process) and product (strategized communication) of strategic communication as narratively constituted and draws a distinction between preceding and proceeding forms of emergence. Preceding forms of emergence address the impact of strategic fashions and peripheral forms of strategizing on strategic communication. Proceeding forms of emergence address strategy attribution and strategy reframing that accompany strategic communication. The article contributes to a meaningful integration of the idea of emergence without tautologizing the concept of strategic communication.
Linking Social Exchange Relations and Creativity through Mediation of Feeling of Energy: An Evidence from IT Firms

This study was aimed to investigate the dynamic role of social exchange relations and energy as an impetus for creative work involvement of IT professionals. One hundred and seventy five employees and sixty four team leaders were inquired at two points of time. At the first instance they were inquired for the perception of social exchange relations; and at the second instance, for energy and creativity. Analysis through structural equation modeling confirmed that social exchange relations (supervisory and coworker support) positively predict employees’ feeling of energy which results in increased level of creative work involvement. This study highlights the significance of social exchange relations by focusing on the energy and creative involvement as an outcome. This study gives a new direction to the social exchange relation and its possible contribution at work. Its results prove that social exchange relations foster energy and lead to an increased level of creative involvement in IT firms. Implications and future directions for researchers are also given.
Phosphoinositide kinase signaling controls ER-PM cross-talk

Phosphoinositide kinase signaling controls a conserved PDK-TORC2-Akt signaling cascade as part of a homeostasis network that allows the ER to modulate essential responses, including Ca2+-regulated lipid biogenesis, upon plasma membrane (PM) stress. Loss of ER-PM junctions impairs this protective response, leading to PM integrity defects upon heat stress.
Complex biosynthesis of the muscle-enriched iron regulator RGMc

The recently discovered repulsive guidance molecule c (RGMc or hemojuvelin) gene encodes a putative glycosylphosphatidylinositol (GPI)-anchored protein that is expressed in striated muscle and in liver. Mutations in this gene have been linked to the severe iron storage disease, juvenile hemochromatosis, although the mechanisms of action of RGMc in iron metabolism are unknown. As a first step toward understanding the molecular physiology of this protein, we studied its biosynthesis, processing and maturation. Production of RGMc occurs as an early and sustained event during skeletal muscle differentiation in culture and is secondary to RGMc gene activation. As assessed by pulse-chase studies and cell-surface labeling experiments, two classes of GPI-anchored and glycosylated RGMc molecules are targeted to the membrane and undergo distinct fates. Full-length RGMc is released from the cell surface and accumulates in extracellular fluid, where its half-life exceeds 24 hours. By contrast, the predominant membrane-associated isoform, a disulfide-linked heterodimer composed of N- and C-terminal fragments, is not found in the extracellular fluid, and is short-lived, as it disappears from the cell surface with a half-life of <3 hours after interruption of protein synthesis. A natural disease-associated RGMc mutant, with valine substituted for glycine at residue 320 (313 in mouse RGMc), does not undergo processing to generate the heterodimeric membrane-linked isoform of RGMc, and is found on the cell surface only as larger protein species. Our results define a series of biosynthetic steps leading to the normal production of different RGMc isoforms in cells, and provide a framework for understanding the biochemical basis of defects in the maturation of RGMc in juvenile hemochromatosis.
A system of grabbing particles related to Galton‐Watson trees

We consider a system of particles with arms that are activated randomly to grab other particles as a toy model for polymerization. We assume that the following two rules are fulfilled: once a particle has been grabbed then it cannot be grabbed again, and an arm cannot grab a particle that belongs to its own cluster. We are interested in the shape of a typical polymer in the situation when the initial number of monomers is large and the numbers of arms of monomers are given by i.i. d. random variables. Our main result is a limit theorem for the empirical distribution of polymers, where limit is expressed in terms of a Galton‐Watson tree. © 2010 Wiley Periodicals, Inc. Random Struct. Alg. , 2010
A Comparative Evaluation of Research vs. Online MT Systems

This paper reports MT evaluation experiments that were conducted at the end of year 1 of the EU-funded CoSyne 1 project for three language combinations, considering translations from German, Italian and Dutch into English. We present a comparative evaluation of the MT software developed within the project against four of the leading free webbased MT systems across a range of state-of-the-art automatic evaluation metrics. The data sets from the news domain that were created and used for training purposes and also for this evaluation exercise, which are available to the research community, are also described. The evaluation results for the news domain are very encouraging: the CoSyne MT software consistently beats the rule-based MT systems, and for translations from Italian and Dutch into English in particular the scores given by some of the standard automatic evaluation metrics are not too distant from those obtained by wellestablished statistical online MT systems.
Behind the lens: police attitudes toward body-worn cameras and organizational justice

ABSTRACT Body-worn cameras are a promising new development in policing. They have been linked to positive outcomes such as decreases in use of force and complaints against officers. However, this new technology has produced a number of issues that could thwart a successful body-worn camera program implementation. One issue is the extent to which officers possess positive attitudes toward using body-worn cameras. If officers do not view body-worn cameras positively, they may not use cameras to their full potential. This study examined the relationship between organizational justice and attitudes toward body-worn cameras in 492 police officers across 3 agencies using structural equation modeling. Findings indicated no observable relationship between perceptions of organizational justice and attitudes toward body-worn cameras. The implications for the organizational adoption of innovations in policy are discussed.
Neutron-Antineutron Oscillation as a Signal of CP Violation

Assuming the Lorentz and CPT invariances we show that neutron-antineutron oscillation implies breaking of CP along with baryon number violation -- i.e. two of Sakharov conditions for baryogenesis. The oscillation is produced by the unique operator in the effective Hamiltonian. This operator mixing neutron and antineutron preserves charge conjugation C and breaks P and T. External magnetic field always leads to suppression of oscillations. Its presence does not lead to any new operator mixing neutron and antineutron.
Use of Awamori-pressed Lees and Tofu Lees as Feed Ingredients for Growing Male Goats

Awamori is produced by fermenting steamed indica rice. Awamori-pressed lees is a by-product of the Awamori production process. Tofu lees is a by-product of the Tofu production process. Research was conducted to test if dried Awamori-pressed lees and Tofu lees can be used as a mixed feed ingredient for raising male goats. Eighteen male kids were divided into three groups of six animals (control feed group (CFG), Awamori-pressed lees mixed feed group (AMFG), Tofu lees mixed feed group (TMFG)). The CFG used feed containing 20% soybean meal as the main protein source, while the AMFG and TMFG used feed mixed with 20% dried Awamori-pressed lees or dried Tofu lees. The groups were fed mixed feed (volume to provide 100 g/d increase in body weight) and alfalfa hay cubes (2.0 kg/d) twice a day (10:00, 16:00). Klein grass hay and water was given ad libitum. Hay intake was measured at 10:00 and 16:00. Body weight and size measurements were taken once a month. At the end of the experiment, a blood sample was drawn from the jugular vein of each animal and the carcass characteristics, the physical and chemical characteristics of loin were analyzed. DCP and TDN intakes in AMFG and TMFG showed no significant difference to the CFG. Cumulative measurements of growth in body weight and size over the 10 mo period in the AMFG and TMFG were similar to the CFG. Blood parameter values were similar to those in normal goats. Dressing carcass weight and percentages, and total weight of meat in the AMFG were similar to that in the CFG, but smaller in the TMFG. The compressed meat juice ratio was higher in both the TMFG and AMFG than the CFG. While the fat in corn, Awamori-pressed lees, and Tofu lees contains more than 50% linoleic acid, the loin fat in both the AMFG and TMFG was very low in linoleic acid due to the increase in the content of oleic acid, stearic acid, and palmitic acid. This indicates that feeding on AMF and TMF does not inhibit hydrogenation by ruminal microorganisms. As in the CFG, the total essential and non-essential amino acids in the loin of the AMFG and TMFG were well balanced. Compared to the CFG, the AMFG and TMFG were high in taurine and carnosine. The results indicate dried Awamori-pressed lees and Tofu lees can be used as a feed ingredient for raising male goats.
Minimally Invasive Techniques to Accelerate the Orthodontic Tooth Movement: A Systematic Review of Animal Studies

Objective. To evaluate various noninvasive and minimally invasive procedures for the enhancement of orthodontic tooth movement in animals. Materials and Methods. Literature was searched using NCBI (PubMed, PubMed Central, and PubMed Health), MedPilot (Medline, Catalogue ZB MED, Catalogue Medicine Health, and Excerpta Medica Database (EMBASE)), and Google Scholar from January 2009 till 31 December 2014. We included original articles related to noninvasive and minimally invasive procedures to enhance orthodontic tooth movement in animals. Extraction of data and quality assessments were carried out by two observers independently. Results. The total number of hits was 9195 out of which just 11 fulfilled the inclusion criteria. Nine articles were good and 5 articles were moderate in quality. Low level laser therapy (LLLT) was among the most common noninvasive techniques whereas flapless corticision using various instruments was among the commonest minimally invasive procedures to enhance velocity of tooth movement. Conclusions. LLLT, low intensity pulsed ultrasound (LIPUS), mechanical vibration, and flapless corticision are emerging noninvasive and minimally invasive techniques which need further researches to establish protocols to use them clinically with conviction.
Phase Plots of Complex Functions: a Journey in Illustration

We propose to visualize complex (meromorphic) functions $f$ by their phase $P_f:=f/|f|$. Color--coding the points on the unit circle converts the function $P_f$ to an image (the phase plot of $f$), which represents the function directly on its domain. We discuss how special properties of $f$ are reflected by their phase plots and indicate several applications. In particular we reformulate a universality theorem for Riemann's Zeta function in the language of phase plots.
Strategy and video-based worksheets for listening comprehension

This qualitative action research studies the contribution of worksheets based on listening strategies and videos to the development of a group of twenty-three eighth graders’ listening comprehension in an EFL context. The study was conducted in a private school located in Bogotá, Colombia. The data-gathering instruments were students' artifacts, teachers' field notes, and focus group interviews. The findings suggest that implementing worksheets focused on listening strategies and videos facilitate the learners’ listening comprehension, increase motivation and lead students to reflect on their own listening performance and progress. Additionally, the findings revealed that the use of videoclips related to the participants’ level, interests and preferences greatly engage them to the listening practice.
