    A case of atypical hyperkalemic periodic paralysis is reported. The diagnosis was confirmed by hyperkalemic test, cold water test, and differentiation of attack period and rest period by the measurement of motor nerve conduction amplitude. Etio-pathology of this disease is discussed from the view of neuroelec-trophysiology.

  2. Na+,K+-pump stimulation improves contractility in isolated muscles of mice with hyperkalemic periodic paralysis. (United States)

    Clausen, Torben; Nielsen, Ole Bækgaard; Clausen, Johannes D; Pedersen, Thomas Holm; Hayward, Lawrence J


    In patients with hyperkalemic periodic paralysis (HyperKPP), attacks of muscle weakness or paralysis are triggered by K(+) ingestion or rest after exercise. Force can be restored by muscle work or treatment with β(2)-adrenoceptor agonists. A missense substitution corresponding to a mutation in the skeletal muscle voltage-gated Na(+) channel (Na(v)1.4, Met1592Val) causing human HyperKPP was targeted into the mouse SCN4A gene (mutants). In soleus muscles prepared from these mutant mice, twitch, tetanic force, and endurance were markedly reduced compared with soleus from wild type (WT), reflecting impaired excitability. In mutant soleus, contractility was considerably more sensitive than WT soleus to inhibition by elevated [K(+)](o). In resting mutant soleus, tetrodotoxin (TTX)-suppressible (22)Na uptake and [Na(+)](i) were increased by 470 and 58%, respectively, and membrane potential was depolarized (by 16 mV, P Na(+),K(+) pump-mediated (86)Rb uptake was 83% larger than in WT. Salbutamol stimulated (86)Rb uptake and reduced [Na(+)](i) both in mutant and WT soleus. Stimulating Na(+),K(+) pumps with salbutamol restored force in mutant soleus and extensor digitorum longus (EDL). Increasing [Na(+)](i) with monensin also restored force in soleus. In soleus, EDL, and tibialis anterior muscles of mutant mice, the content of Na(+),K(+) pumps was 28, 62, and 33% higher than in WT, respectively, possibly reflecting the stimulating effect of elevated [Na(+)](i) on the synthesis of Na(+),K(+) pumps. The results confirm that the functional disorders of skeletal muscles in HyperKPP are secondary to increased Na(+) influx and show that contractility can be restored by acute stimulation of the Na(+),K(+) pumps. Calcitonin gene-related peptide (CGRP) restored force in mutant soleus but caused no detectable increase in (86)Rb uptake. Repeated excitation and capsaicin also restored contractility, possibly because of the release of endogenous CGRP from nerve endings in the isolated

    Hyperkalemia manifests clinically with acute neuromuscular paralysis, which can simulate Guillain Barr? syndrome (GBS) and other causes of acute flaccid paralysis. Primary hyperkalemic paralysis occurs from genetic defects in the sodium channel, and secondary hyperkalemic paralysis (SHP) from diverse causes including renal dysfunction, potassium retaining drugs, Addison's disease, etc. Clinical characteristics of SHP have been addressed in a number of publications. However, electrophysiologic...

    Full Text Available Purpose: This study aims to analyze the financial and economic health of the Catalan family companies with high growth during the crisis period (2008-2013, as an engine of job creation and economic development of the territory, identifying the economic and financial characteristics. Design/methodology/approach: The data used comes from the financial statements of the high growth Catalan companies during the crisis period of 2008-2013, in particular it collects a sample of the 140 high growth Catalan companies where a 70% of them are family businesses, there is a financial and economic analysis using descriptive statistics of these family businesses with a regression model to achieve results and conclusions. Findings: During the 2008-2013 crisis, Catalan family companies with high growth that are mostly small businesses have a good economic and financial health, with moderate innovation and a great potential for survival. Research limitations/implications: It would be convenient to make the same study in similar territories where most of the companies are family businesses, in order to compare the financial and economic analysis, valuing the impact of these companies in the business. Practical implications: It allows valuing the projection of these kinds of family companies, mostly in Catalonia, in a financial and economic level, identifying if they have a proper financial strategy. Social implications: The results show that these companies have great financial and economic health and have a better response during a crisis period. Originality / value: The study shows that family businesses have moderate indebtedness and acceptable rendibility in the crisis period, although, since they are small businesses the lack of innovation and patents can lead to future problems.

  8. Effect of Intravenous Small-Volume Hypertonic Sodium Bicarbonate, Sodium Chloride, and Glucose Solutions in Decreasing Plasma Potassium Concentration in Hyperkalemic Neonatal Calves with Diarrhea. (United States)

    Trefz, F M; Constable, P D; Lorenz, I


    Hyperkalemia is a frequently observed electrolyte imbalance in dehydrated neonatal diarrheic calves that can result in skeletal muscle weakness and life-threatening cardiac conduction abnormalities and arrhythmias. Intravenous administration of a small-volume hypertonic NaHCO 3 solution is clinically more effective in decreasing the plasma potassium concentration (cK) in hyperkalemic diarrheic calves than hypertonic NaCl or glucose solutions. Twenty-two neonatal diarrheic calves with cK >5.8 mmol/L. Prospective randomized clinical trial. Calves randomly received either 8.4% NaHCO 3 (6.4 mL/kg BW; n = 7), 7.5% NaCl (5 mL/kg BW; n = 8), or 46.2% glucose (5 mL/kg BW; n = 7) IV over 5 minutes and were subsequently allowed to suckle 2 L of an electrolyte solution. Infusions with NaHCO 3 and NaCl provided an identical sodium load of 6.4 mmol/kg BW. Hypertonic NaHCO 3 infusions produced an immediate and sustained decrease in plasma cK. Hypertonic glucose infusions resulted in marked hyperglycemia and hyperinsulinemia, but cK remained unchanged for 20 minutes. Between 30 and 120 minutes after initiation of treatment, the most marked decrements in cK from baseline occurred in group NaHCO 3 , which were significantly (P < .05) larger during this period of time than in calves in group NaCl, but not group glucose. After 120 minutes, the mean decrease in cK from baseline was -26 ± 10%, -9 ± 8%, and -22 ± 6% in groups NaHCO 3 , NaCl, and glucose, respectively. Small-volume hypertonic NaHCO 3 infusions appear to have clinical advantages for the rapid resuscitation of hyperkalemic diarrheic calves, compared to hypertonic NaCl or glucose solutions.

  9. Anaesthetic management of a patient with familial normokalaemic periodic paralysis.

    LENUS (Irish Health Repository)

    Walsh, F


    PURPOSE: We describe the anaesthetic management of a patient with the autosomal dominant inherited disease, normokalaemic periodic paralysis. The disease results in intermittent bouts of limb and respiratory muscular weakness in association with hypothermia, stress, prolonged fasting or exercise. Unlike hypokalaemic and hyperkalaemic periodic paralysis, the more common variants of the disease, normokalaemic periodic paralysis is not accompanied by alterations in the plasma potassium concentration. CLINICAL FEATURES: A five-year-old boy presented for emergency scrotal exploration. He had a family history of periodic paralysis and had experienced previous episodes of weakness, two of which had required hospitalization for respiratory distress. On admission there was no evidence of weakness and serum potassium concentration was 4.2 mMol.L-1. A spinal anaesthetic was performed and the procedure was uncomplicated by muscle paralysis above the level of the spinal block. CONCLUSION: Avoidance of known precipitating factors and judicious use of neuromuscular blocking drugs has been advocated in patients with this disorder presenting for surgery. In appropriate circumstances, spinal anaesthesia represents a useful option in patients with normokalaemic periodic paralysis.

  10. On critical values concerning the evolution of the long period families

    Hou Xiyun


    In a previous paper, we proposed another special critical value concerning the evolution of the long period family around the equilateral equilibrium points, besides the two values given by Henrard. Are there any other special critical values? After studying the stability curves of the long period family carefully, we gave a negative answer. During the study, we found an interesting family of periodic orbits which we called the homo family. We studied the evolution of this family following the increase of μ. With these findings, we were able to explain the origin of the four branches of periodic families emanating from L 4 and the stability results of the equilateral equilibrium points.

  11. Caffey disease in neonatal period: the importance of the family! (United States)

    Prior, Ana Rita; Moldovan, Oana; Azevedo, António; Moniz, Carlos


    A male newborn was apparently well until his second day of life, when increased irritability and a swelling in his right leg were noted. He was rooming-in with his mother since birth. On examination, a mass on the anterior surface of the right leg was noticed. The mass was firm, elongated, ill-defined, unmovable and painful at palpation. No overlying skin changes were seen. The newborn had a family history of neonatal bone swelling with resolution before the age of 2. Subsequent images showed hyperostosis in the diaphysis of the right tibia. After exclusion of other conditions such as trauma, osteomyelitis and congenital syphilis, the involvement of the tibial diaphysis, sparing the epiphyses and the benign course of the disease in family history, were indicative of Caffey disease. The genetic study confirmed this diagnosis. Caffey disease, although rare, should not be overlooked in the diagnostic approach to childhood bone swelling.

  14. Genealogy and stability of periodic orbit families around uniformly rotating asteroids (United States)

    Hou, Xiyun; Xin, Xiaosheng; Feng, Jinglang


    Resonance orbits around a uniformly rotating asteroid are studied from the approach of periodic orbits in this work. Three periodic families (denoted as I, II, and III in the paper) are fundamental in organizing the resonance families. For the planar case: (1) Genealogy and stability of Families I, II and the prograde resonance families are studied. For extremely irregular asteroids, family genealogy close to the asteroid is greatly distorted from that of the two body-problem (2BP), indicating that it is inappropriate to treat the orbital motions as perturbed Keplerian orbits. (2) Genealogy and stability of Family III are also studied. Stability of this family may be destroyed by the secular resonance between the orbital ascending node's precession and the asteroid's rotation. For the spatial case: (1) Genealogy of the near circular three-dimensional periodic families are studied. The genealogy may be broken apart by families of eccentric frozen orbits whose argument of perigee is ;frozen; in space. (2) The joint effects between the secular resonance and the orbital resonances may cause instability to three-dimensional orbital motion with orbit inclinations close to the critical values. Applying the general methodology to a case study - the asteroid Eros and also considering higher order non-spherical terms, some extraordinary orbits are found, such as the ones with orbital plane co-rotating with the asteroid, and the stable frozen orbits with argument of perigee librating around values different from 0°, 90°, 180°, 270°.

  16. Experiences of counselling in the emergency department during the waiting period: importance of family participation. (United States)

    Paavilainen, Eija; Salminen-Tuomaala, Mari; Kurikka, Sirpa; Paussu, Paula


    To describe patients' experiences of counselling, defined as information giving and advice by nursing staff, in the emergency department. A particular focus was on the waiting period and on the importance of family participation in counselling. Counselling is a widely studied topic in nursing. Too little is known about counselling in emergency departments and especially about participation of family members and suitability of counselling for the patient's life situation. Descriptive quantitative study. Data were collected by questionnaires from patients (n = 107) visiting a hospital emergency department. The data were subjected to statistical analysis. Forty-two per cent of patients arrived at the emergency department with a family member: spouse or cohabiting partner, mother, father or daughter. Patients were fairly satisfied with the counselling. The presence of a family member was important to the majority of patients (75%). About half of the patients wanted information concerning their illness, condition and treatment to be given to their family members. Those visiting the department with a family member were more satisfied with counselling and felt that it promoted their participation in care. It is to encourage patients' family members to participate in counselling situations in emergency departments. However, the type of information passed on to family members should be carefully discussed and prepared. Patients' family members seem to be important partners in counselling situations. The presence of family members supports patients in the emergency department during the waiting period and helps them orientate in their situation. When family members are present, issues which patients wish to discuss should be carefully planned. Family presence should be encouraged in emergency departments.

  17. More than six hundred new families of Newtonian periodic planar collisionless three-body orbits (United States)

    Li, XiaoMing; Liao, ShiJun


    The famous three-body problem can be traced back to Isaac Newton in the 1680s. In the 300 years since this "three-body problem" was first recognized, only three families of periodic solutions had been found, until 2013 when Šuvakov and Dmitrašinović [Phys. Rev. Lett. 110, 114301 (2013)] made a breakthrough to numerically find 13 new distinct periodic orbits, which belong to 11 new families of Newtonian planar three-body problem with equal mass and zero angular momentum. In this paper, we numerically obtain 695 families of Newtonian periodic planar collisionless orbits of three-body system with equal mass and zero angular momentum in case of initial conditions with isosceles collinear configuration, including the well-known figure-eight family found by Moore in 1993, the 11 families found by Šuvakov and Dmitrašinović in 2013, and more than 600 new families that have never been reported, to the best of our knowledge. With the definition of the average period T = T/L f, where L f is the length of the so-called "free group element", these 695 families suggest that there should exist the quasi Kepler's third law T* ≈ 2:433 ± 0:075 for the considered case, where T ≈ = T | E|3/2 is the scale-invariant average period and E is its total kinetic and potential energy, respectively. The movies of these 695 periodic orbits in the real space and the corresponding close curves on the "shape sphere" can be found via the website:

    The discovery of binary and triple asteroids in addition to the execution of space missions to minor celestial bodies in the past several years have focused increasing attention on periodic orbits around irregular-shaped celestial bodies. In the present work, we adopt a polyhedron shape model for providing an accurate representation of irregular-shaped bodies and employ the model to calculate their corresponding gravitational and effective potentials. We also investigate the characteristics of periodic orbit families and the continuation of periodic orbits. We prove a fact, which provides a conserved quantity that permits restricting the number of periodic orbits in a fixed energy curved surface about an irregular-shaped body. The collisions of Floquet multipliers are maintained during the continuation of periodic orbits around the comet 1P/Halley. Multiple bifurcations in the periodic orbit families about irregular-shaped bodies are also discussed. Three bifurcations in the periodic orbit family have been found around the asteroid 216 Kleopatra, which include two real saddle bifurcations and one period-doubling bifurcation.

    this study aimed to explore new parents' views and experiences during their transition to parenthood. in China the one-child birth policy may bring more stress and challenges for the new parents due to the lack of experience and greater expectations of their new role. China is also at a stage of rapid economic and social development which creates new conditions for parenthood. a cross-sectional survey was conducted from February to September 2009 among 232 mothers and fathers, yielding a 83.6% response rate (n=194 couples). The questionnaire included: the Family Assessment Device-General Function Scale, the Family Resources Scale, the Family Adaptation Scale, and the Chinese Perceived Stress Scale. there were no significant differences between mothers' adaptation and fathers' adaptation during the postpartum period, as well as their perceived stress, family function and family resources (p>0.05). Method of childbirth was not related to adaptation. About 29% of variance in mothers' adaptation could be explained by satisfaction with the infant's gender (B=0.295, padaptation (B=0.236, padaptation could be explained by mothers' adaptation (B=0.268, pimportance of family resources to family adaptation and antenatal and postnatal education programmes as part of family-centred care. The possible influences of culture and policies need to be considered by health-care professionals developing strategies to facilitate family adaptation to the early parenthood.

  1. Families of periodic orbits in Hill's problem with solar radiation pressure: application to Hayabusa 2 (United States)

    Giancotti, Marco; Campagnola, Stefano; Tsuda, Yuichi; Kawaguchi, Jun'ichiro


    This work studies periodic solutions applicable, as an extended phase, to the JAXA asteroid rendezvous mission Hayabusa 2 when it is close to target asteroid 1999 JU3. The motion of a spacecraft close to a small asteroid can be approximated with the equations of Hill's problem modified to account for the strong solar radiation pressure. The identification of families of periodic solutions in such systems is just starting and the field is largely unexplored. We find several periodic orbits using a grid search, then apply numerical continuation and bifurcation theory to a subset of these to explore the changes in the orbit families when the orbital energy is varied. This analysis gives information on their stability and bifurcations. We then compare the various families on the basis of the restrictions and requirements of the specific mission considered, such as the pointing of the solar panels and instruments. We also use information about their resilience against parameter errors and their ground tracks to identify one particularly promising type of solution.

  2. Numerical continuation of families of heteroclinic connections between periodic orbits in a Hamiltonian system (United States)

    Barrabés, E.; Mondelo, J. M.; Ollé, M.


    This paper is devoted to the numerical computation and continuation of families of heteroclinic connections between hyperbolic periodic orbits (POs) of a Hamiltonian system. We describe a method that requires the numerical continuation of a nonlinear system that involves the initial conditions of the two POs, the linear approximations of the corresponding manifolds and a point in a given Poincaré section where the unstable and stable manifolds match. The method is applied to compute families of heteroclinic orbits between planar Lyapunov POs around the collinear equilibrium points of the restricted three-body problem in different scenarios. In one of them, for the Sun-Jupiter mass parameter, we provide energy ranges for which the transition between different resonances is possible.

  3. Sensitive Periods, Vasotocin-Family Peptides, and the Evolution and Development of Social Behavior

    Directory of Open Access Journals (Sweden)

    Nicole M. Baran


    Full Text Available Nonapeptides, by modulating the activity of neural circuits in specific social contexts, provide an important mechanism underlying the evolution of diverse behavioral phenotypes across vertebrate taxa. Vasotocin-family nonapeptides, in particular, have been found to be involved in behavioral plasticity and diversity in social behavior, including seasonal variation, sexual dimorphism, and species differences. Although nonapeptides have been the focus of a great deal of research over the last several decades, the vast majority of this work has focused on adults. However, behavioral diversity may also be explained by the ways in which these peptides shape neural circuits and influence social processes during development. In this review, I synthesize comparative work on vasotocin-family peptides during development and classic work on early forms of social learning in developmental psychobiology. I also summarize recent work demonstrating that early life manipulations of the nonapeptide system alter attachment, affiliation, and vocal learning in zebra finches. I thus hypothesize that vasotocin-family peptides are involved in the evolution of social behaviors through their influence on learning during sensitive periods in social development.

  4. Familial risks of breast and prostate cancers: does the definition of the at risk period matter? (United States)

    Brandt, Andreas; Bermejo, Justo Lorenzo; Sundquist, Jan; Hemminki, Kari


    'Being at familial risk' may have different connotations in studies on familial risk of cancer. The register-based definition of a family history considers individuals with an affected relative at familial risk independently of the family member's diagnostic time. Alternatively, the individuals are classified to be at familial risk only after the diagnosis date of their relative, relevant to clinical counselling and screening situations. The aim of this study was to compare familial breast and prostate cancer risks according to the two definitions. The nationwide Swedish Family-Cancer Database with information on cancers from 1958 to 2006 was used to calculate the hazard ratio of breast and prostate cancers according to family history using Cox regression. Family history was defined considering the number and type of affected relatives and the relative's diagnostic age, respectively. Individuals were considered at familial risk from their entry to the study or, alternatively, from the diagnostic time of the relative. Hazard ratios were equal whether individuals were considered at risk independent of the relative's diagnostic date or only after the relative's diagnostic date. These results indicate that studies on familial breast or prostate cancer risk which do not take the relative's diagnosis date into account are applicable to screening and clinical counselling situations. The estimates according to the register-based definition are based on larger numbers of patients, which may be crucial for analysis of small groups such as families of multiple cases.

  8. Malaysia family-planning centers strive to maintain gains won in 15-year period. (United States)

    Roemer, R


    Family planning in Malaysia is discussed. Family planning began in Malaysia about 15 years ago through the efforts of voluntary family Planning Associations in the various Malay states. In 1966 the Malaysian Parliament passed the National Family Planning Act setting up the National FAmily Planning Board to formulate policies and methods for the promotion and spread of family planning knowledge and practice on the grounds of health of mothers and children and welfare of the family. In 1967, the board set a target of 40,000 new acceptors of family planning and 90% of the target was reached. This represents 3% of the child-bearing married women aged 15-49. The target for 1968 of 65,000 new acceptors is being achieved. A survey of acceptors is to be carried out from December 1968 to April 1969 to ascertain how many women who accepted family planning continue to practice it. Malaysia's crude birth rate declined from 46.2 in 1957 to 37.3 in 1966 before the government program was instituted. Abortion attempts have been frequent. The main method of contraception used is oral contraceptives. According to a 1957 survey, 31% of the married women in the metropolitan areas and 2% of rural women were using contraception. Presently, in Malaysia there is a need to: 1) train personnel to provide services, 2) inform and motivate families to accept family planning, 3) continue a broad educational program, 4) reform Malaysia's antiquated abortion law, and 5) integrate family planning services more fully into the general health services of the country.

  9. Periodic solutions for a non-monotone family of delayed differential equations with applications to Nicholson systems (United States)

    Faria, Teresa


    For a family of n-dimensional periodic delay differential equations which encompasses a broad set of models used in structured population dynamics, the existence of a positive periodic solution is obtained under very mild conditions. The proof uses the Schauder fixed point theorem and relies on the permanence of the system. A general criterion for the existence of a positive periodic solution for Nicholson's blowflies periodic systems (with both distributed and discrete time-varying delays) is derived as a simple application of our main result, generalizing the few existing results concerning multi-dimensional Nicholson models. In the case of a Nicholson system with discrete delays all multiples of the period, the global attractivity of the positive periodic solution is further analyzed, improving results in recent literature.

  10. [The decision making process of ESRD families during the dialysis withdrawal period]. (United States)

    Lin, Tsai-Rung


    Hemodialysis is a financial burden to the state and families and the cause of much suffering in patients. It is a life prolonging therapy and death-delaying treatment. When the burdens of therapy substantially outweigh its benefits, withdrawal from dialysis is an appropriate option. However, considering the ethical and legal concerns of doing such is something families must face. There has been little research and little understanding of the process of decision-making within families in Taiwan. The process is full of conflicts, worries, guilt, shame, and lack of consensus. Effective communication with the medical team to resolve the conflict and describe the prognosis is necessary in order to reach a consensus and move toward palliative care. The article uses a case report and discusses the process. Finally, the author suggests an approach to making the situation better in the future.

  12. "Nothing special, everything is maamuli": socio-cultural and family practices influencing the perinatal period in urban India. (United States)

    Raman, Shanti; Srinivasan, Krishnamachari; Kurpad, Anura; Razee, Husna; Ritchie, Jan

  16. Family planning use and its associated factors among women in the extended postpartum period in Addis Ababa, Ethiopia. (United States)

    Gebremedhin, Almaz Yirga; Kebede, Yigzaw; Gelagay, Abebaw Addis; Habitu, Yohannes Ayanaw


    Postpartum period is an important entry point for family planning service provision; however, women in Ethiopia are usually uncertain about the use of family planning methods during this period. Limited studies have been conducted to assess postpartum family planning use in Addis Ababa, in particular and in the country in general. So, this study was conducted to assess postpartum family planning use and its associated factors among women in extended postpartum period in Kolfe Keranyo sub city of Addis Ababa. A community-based cross sectional study was conducted from May to June 2015 on 803 women who have had live births during the year (2014) preceding the data collection in the sub city. The multi-stage cluster sampling technique was used to select study participants. Data were collected by interviewer administered structured questionnaire, entered into EPI INFO version 7 and analyzed by SPSS Version 20. Bivariable and Multivariable logistic regression models were employed to see the presence and strength of the association between the dependent and independent variables by computing the odds ratios with a 95% confidence intervals and p -values. The prevalence of postpartum family planning use was 80.3% (95% CI: 74.5, 83.1). Marriage, (AOR 0.09, 95% CI: 0.03, 0.22), menses resumption after birth, (AOR 2.12, 95% CI: 1.37, 3.41), length of time after delivery, (AOR 2.37, 95% CI: 1.18, 4.75), and history of contraceptive use before last pregnancy, (AOR 0.12, 95% CI: 0.07, 0.18) were the factors associated with postpartum family planning use. The prevalence of postpartum family planning use was high and the main factors associated with it were marriage, menses resumption, length of time after delivery, and history of previous contraceptive use. Therefore women should get appropriate information about the possibility of exposure to pregnancy prior to menses resumption by giving special emphasis to those who had no previous history of contraceptive use and exposure to

    In this paper we consider a two-dimensional piecewise-smooth discontinuous map representing the so-called 'relative dynamics' of an Hicksian business cycle model. The main features of the dynamics occur in the parameter region in which no fixed points at finite distance exist, but we may have attracting cycles of any periods. The bifurcations associated with the periodicity tongues of the map are studied making use of the first-return map on a suitable segment of the phase plane. The bifurcation curves bounding the periodicity tongues in the parameter plane are related with saddle-node and border-collision bifurcations of the first-return map. Moreover, the particular 'sausages structure' of the bifurcation tongues is also explained

  18. Choroidal Thickness Changes in the Acute Attack Period in Patients with Familial Mediterranean Fever. (United States)

    Gundogan, Fatih C; Akay, Fahrettin; Uzun, Salih; Ozge, Gokhan; Toyran, Sami; Genç, Halil


    The aim of this study was to evaluate choroidal thickness changes during acute attacks of familial Mediterranean fever (FMF). Fifty patients with FMF and 50 healthy controls were included. Choroidal thickness of each participant was measured at the foveola and horizontal nasal and temporal quadrants at 500-µm intervals to 1,500 µm from the foveola using spectral-domain optical coherence tomography. White blood cell count, erythrocyte sedimentation rate (ESR) and serum levels of fibrinogen and C-reactive protein (CRP) were evaluated. The clinical findings (peritonitis, arthritis and pleuritis) were noted. Choroidal thickness was significantly thicker at all measurement points in FMF patients compared to healthy controls during an acute attack (p 0.05). Increased choroidal thickness in the acute phase of FMF is possibly related to the inflammatory edematous changes in the choroid. © 2015 S. Karger AG, Basel.

  19. Barium-induced skeletal muscle paralysis in the rat, and its relationship to human familial periodic paralysis (United States)

    Schott, G. D.; McArdle, B.


    An in vivo study of skeletal muscle paralysis induced by intravenous barium chloride has been made in curarized and non-curarized rats. The influence of potassium and calcium chlorides, propranolol, ouabain, and prior adrenalectomy on the paralysis has also been studied. Paralysis is found to be due to a direct effect on skeletal muscle, and to correlate well with the development of hypokalaemia. Possible mechanisms of action of barium are discussed, and attention is drawn to the similarity between barium poisoning and hypokalaemic familial periodic paralysis. PMID:4813426

  20. Fully Numerical Methods for Continuing Families of Quasi-Periodic Invariant Tori in Astrodynamics (United States)

    Baresi, Nicola; Olikara, Zubin P.; Scheeres, Daniel J.


    Quasi-periodic invariant tori are of great interest in astrodynamics because of their capability to further expand the design space of satellite missions. However, there is no general consent on what is the best methodology for computing these dynamical structures. This paper compares the performance of four different approaches available in the literature. The first two methods compute invariant tori of flows by solving a system of partial differential equations via either central differences or Fourier techniques. In contrast, the other two strategies calculate invariant curves of maps via shooting algorithms: one using surfaces of section, and one using a stroboscopic map. All of the numerical procedures are tested in the co-rotating frame of the Earth as well as in the planar circular restricted three-body problem. The results of our numerical simulations show which of the reviewed procedures should be preferred for future studies of astrodynamics systems.

  1. Quasi-periodic motions in families of dynamical systems order amidst chaos

    CERN Document Server

    Broer, Hendrik W; Sevryuk, Mikhail B


    This book is on Kolmogorov-Arnol'd-Moser theory for quasi-periodic tori in dynamical systems. It gives an up-to-date report on the role parameters play for persis- tence of such tori, typically occuring on Cantor sets of positive Hausdorff measure inside phase and parameter space. The cases with preservation of symplectic or volume forms or time-reversal symmetries are included. The concepts of Whitney-smoothness and Diophantine approximation of Cantor sets on submanifolds of Euclidean space are treated, as well as Bruno's theory on analytic continuation of tori. Partly this material is new to Western mathematicians. The reader should be familiar with dynamical systems theory, differen- tial equations and some analysis. The book is directed to researchers, but its entrance level is introductory.

    Kazantzis, P.G.


    New families of three-dimensional double-symmetric periodic orbits are determined numerically in the Sun-Jupiter case of the restricted three-body problem. These families bifurcate from the 'vertical-critical' orbits (αsub(ν) = -1, csub(ν) = 0) of the 'basic' plane families i. g 1 g 2 h, a, m and I. Further the numerical procedure employed in the determination of these families has been described and interesting results have been pointed out. Also, computer plots of the orbits of these families have been shown in conical projections. (orig.)

    Familial Mediterranean fever (FMF) is an autoinflammatory, autosomal recessive, inherited disease characterized by recurrent self-limiting attacks of serosal surfaces. The imbalance of oxidants/antioxidants may play a role in such attacks. In this study, we aimed to evaluate the relationship between serum paraoxonase (PON1) activity, PON1 phenotype, and other parameters in patients with FMF and healthy controls. A total of 120 FMF patients with an attack-free period (AFP) and 65 healthy subjects were included in this study. The serum PON1 activity, stimulated paraoxonase (SPON) activity, PON1 phenotype (representing Q192R polymorphism; QQ, QR, RR), arylesterase activity, total oxidant status (TOS), total antioxidant capacity (TAC), oxidative stress index (OSI), advanced oxidative protein products (AOPP), total thiols (TTL), and ischemia-modified albumin (IMA) and cystatin-c (CYS-C) levels were measured. For the QQ phenotype, the median TTL and AOPP levels of the control group were 264.50 (57.75) mol/L and 21.26 (21.17) mmol/L, respectively, whereas the median TTL, AOPP levels of the patients were 309.00 (47.00) mol/L and 12.98 (6.96) mmol/L, respectively. There was a statistically significant difference between the patients and controls with the QQ phenotype in terms of TTL and AOPP (pantioxidant parameters were similar among the patients during AFP and the controls.

  5. Family Violence and Maltreatment of Women During the Perinatal Period: Associations with Infant Morbidity in Indian Slum Communities. (United States)

    Silverman, Jay G; Balaiah, Donta; Decker, Michele R; Boyce, Sabrina C; Ritter, Julie; Naik, D D; Nair, Saritha; Saggurti, Niranjan; Raj, Anita


    To determine the prevalence of non-violent, gender-based forms of maltreatment of women by husbands and in-laws [i.e., gender-based household maltreatment (GBHM)] during pregnancy and postpartum; to clarify the role of GBHM in compromising infant health, and whether this role extends beyond that previously observed for intimate partner violence (IPV). Cross-sectional, quantitative data were collected from women (ages 15-35) seeking immunizations for their infants violence and GBHM) and recent infant morbidity (diarrhea, respiratory distress, fever, colic and vomiting). More than one in four women (28.4%) reported IPV during their recent pregnancy and/or during the postpartum period, 2.6% reported perinatal violence from in-laws, and 49.0% reported one or more forms of perinatal GBHM. In adjusted regression models that included all forms of family violence and maltreatment, perinatal GBHM remained significantly associated with infant morbidity (AORs 1.4-1.9); perinatal IPV and in-law violence ceased to predict infant morbidity in models including GBHM. Findings indicate that non-violent expressions of gender inequity (e.g., nutritional deprivation, deprivation of sleep, blocking access to health care during pregnancy) are more strongly associated with poor infant health than physical or sexual violence from husbands or in-laws in urban India. These results strongly suggest the need to expand the conception of gender inequities beyond IPV to include non-violent forms of gendered mistreatment in considering their impact on infant health.

  6. [Impact of maternal HIV status on family constructions and the infant's relational environment during the perinatal period]. (United States)

    Trocmé, N; Courcoux, M-F; Tabone, M-D; Leverger, G; Dollfus, C


    To assess whether maternal HIV-positive status negatively affects family construction and the child's psychological environment. Could this be responsible for behavioral problems observed in children infected with or affected by HIV? Interviews were conducted with 60 HIV+ mothers and their infants during the perinatal period, within 3 months of delivery, collected at the time of a pediatric outpatient visit within a PMTCT program. Half of the 60 mothers did not live with the infant's father, 56% of multiparous mothers were separated from their previous children. Sixty-five percent of the fathers were informed of the mother's HIV-positive status, although 90% of fathers who lived with the mothers were informed. During pregnancy, 80% of mothers reported psychological stress; after delivery, 72% of mothers suffered from not being allowed to breastfeed their infants, 43.5% expressed a fear of transmitting the infection to the child, and 40% avoided contacts with the infant. The impact of the mother's psychological stress and anxiety related to the risk of HIV transmission through breastfeeding and casual contacts were already noticeable in the first mother-child interrelations. Although the risk of MTC transmission in now very small, psychological troubles related to maternal HIV status may negatively affect the children's well-being and behavior, psychological support should be provided for mothers and children as part of comprehensive services.

  7. Evolution of embryonic developmental period in the marine bird families Alcidae and Spheniscidae: roles for nutrition and predation? (United States)

    Hipfner, J Mark; Gorman, Kristen B; Vos, Rutger A; Joy, Jeffrey B


    Nutrition and predation have been considered two primary agents of selection important in the evolution of avian life history traits. The relative importance of these natural selective forces in the evolution of avian embryonic developmental period (EDP) remain poorly resolved, perhaps in part because research has tended to focus on a single, high taxonomic-level group of birds: Order Passeriformes. The marine bird families Alcidae (auks) and Spheniscidae (penguins) exhibit marked variation in EDP, as well as behavioural and ecological traits ultimately linked to EDP. Therefore, auks and penguins provide a unique opportunity to assess the natural selective basis of variation in a key life-history trait at a low taxonomic-level. We used phylogenetic comparative methods to investigate the relative importance of behavioural and ecological factors related to nutrition and predation in the evolution of avian EDP. Three behavioural and ecological variables related to nutrition and predation risk (i.e., clutch size, activity pattern, and nesting habits) were significant predictors of residual variation in auk and penguin EDP based on models predicting EDP from egg mass. Species with larger clutch sizes, diurnal activity patterns, and open nests had significantly shorter EDPs. Further, EDP was found to be longer among birds which forage in distant offshore waters, relative to those that foraged in near shore waters, in line with our predictions, but not significantly so. Current debate has emphasized predation as the primary agent of selection driving avian life history diversification. Our results suggest that both nutrition and predation have been important selective forces in the evolution of auk and penguin EDP, and highlight the importance of considering these questions at lower taxonomic scales. We suggest that further comparative studies on lower taxonomic-level groups will continue to constructively inform the debate on evolutionary determinants of avian EDP, as

  9. The Phenomenon of a Burgher Family in the Early Modern Period/ [Fenomen rodziny mieszczańskiej we wczesnych wiekach nowożytnych

    Directory of Open Access Journals (Sweden)



    Full Text Available The function of a burgher family passed through changes depending upon historical conditions and power relations. Every family member had its social role within the family framework. Family members followed stabilisedpattem ofbehaviour influenced by personal motivation. In the era of the early modem period the original forms of social life of the burghers passed through weakening and a polarisation of the małe and female role was strengthening. That was the beginning of a gradual division process of home and public sphere leading to a formation of a burgher model of traditional roles of husband and wife. These changes were being reflected in gradual transferring of productive eaming activities from the home sphere to the public sphere. In the pre-industrial phase of early modem period the burgher women, particularly those that took part in productive and economic entrepreneurial activities with their husbands, were relatively more independent and free than the women in industrial period when the role of women was understood as a guardian of the family hearth. With the modemisation and democratisation of the society a burgher model of a good wife and a polarisation of both genders were gradually pushing ahead. The dependence of the wife on the husband was not economic only. The wife had to subordinate her life plans to the career of her husband in public sphere and concentrate to the home sphere.

  10. Social support among HIV-positive and HIV-negative adolescents in Umlazi, South Africa: changes in family and partner relationships during pregnancy and the postpartum period. (United States)

    Hill, Lauren M; Maman, Suzanne; Groves, Allison K; Moodley, Dhayendre


    Pregnancy is common among adolescents in South Africa, yet the social experiences of adolescents during the pregnancy and postpartum period remain understudied in this context. We aimed to explore how adolescent women's discovery and disclosure of both their pregnancy and HIV status affected their relationships with family members and sexual partners, with a particular focus on whether and how support changed throughout this time period. We conducted in-depth semi-structured interviews with 15 HIV-positive and HIV-negative adolescent women who were either pregnant or had delivered in the last 18 months from one urban clinic in Umlazi, South Africa. Interviews were audiotaped, transcribed, translated, and coded for analysis. Young women described stress and instability in their relationships with family and partners during pregnancy and the postpartum period, though prior to and during HIV-status disclosure women generally experienced less stress than in disclosing their pregnancy to family members and partners. After a destabilizing period immediately following pregnancy disclosure, families became and remained the primary source of material and emotional support for the young women. Women discussed heightened closeness with their partners during pregnancy, but few women had close relationships with their partners postpartum. Support experiences did not differ by HIV status. Programs should be aware of the relative importance of pregnancy-related concerns over HIV-related concerns in this population of young women. Engaging family members is critical in ensuring social support for this population of young pregnant women, and in encouraging timely initiation of antenatal care.

  11. Building CX peanut-shaped disk galaxy profiles. The relative importance of the 3D families of periodic orbits bifurcating at the vertical 2:1 resonance (United States)

    Patsis, P. A.; Harsoula, M.


    Context. We present and discuss the orbital content of a rather unusual rotating barred galaxy model, in which the three-dimensional (3D) family, bifurcating from x1 at the 2:1 vertical resonance with the known "frown-smile" side-on morphology, is unstable. Aims: Our goal is to study the differences that occur in the phase space structure at the vertical 2:1 resonance region in this case, with respect to the known, well studied, standard case, in which the families with the frown-smile profiles are stable and support an X-shaped morphology. Methods: The potential used in the study originates in a frozen snapshot of an N-body simulation in which a fast bar has evolved. We follow the evolution of the vertical stability of the central family of periodic orbits as a function of the energy (Jacobi constant) and we investigate the phase space content by means of spaces of section. Results: The two bifurcating families at the vertical 2:1 resonance region of the new model change their stability with respect to that of most studied analytic potentials. The structure in the side-on view that is directly supported by the trapping of quasi-periodic orbits around 3D stable periodic orbits has now an infinity symbol (i.e. ∞-type) profile. However, the available sticky orbits can reinforce other types of side-on morphologies as well. Conclusions: In the new model, the dynamical mechanism of trapping quasi-periodic orbits around the 3D stable periodic orbits that build the peanut, supports the ∞-type profile. The same mechanism in the standard case supports the X shape with the frown-smile orbits. Nevertheless, in both cases (i.e. in the new and in the standard model) a combination of 3D quasi-periodic orbits around the stable x1 family with sticky orbits can support a profile reminiscent of the shape of the orbits of the 3D unstable family existing in each model.

  12. The course and impact of family optimism in the post-acute period after acquired brain injury. (United States)

    Riley, Gerard A; Hough, Andrea; Meader, Laura M; Brennan, Andrew J


    To investigate the course and impact of family optimism in the post-acute stage of acquired brain injury. At Time 1, 30 family relatives of in-patients in rehabilitation units and 30 relatives of patients recently discharged from such units completed questionnaires relating to their emotional health, engagement in the rehabilitation process and expectations about the future consequences and controllability of the injury. At Time 2 (12-18 months later), 23 of the original sample completed questionnaires about their emotional health and actual consequences and controllability of the injury. At Time 1, optimism about future consequences and controllability was associated with greater engagement in the rehabilitation process and better emotional health. The two groups did not differ on any of the measures, which did not support the expectation that the patient's discharge home would trigger a loss of optimism and emotional upset for the family. At Time 2, the actual consequences were worse than had been expected at Time 1 and greater disappointment was associated with a greater decline in emotional wellbeing. Family expectations about recovery are linked with important variables such as emotional wellbeing and engagement in the rehabilitation process and need careful management by clinicians.

  15. Chromosomal radiosensitivity during the G2 cell-cycle period of skin fibroblasts from individuals with familial cancer

    International Nuclear Information System (INIS)

    Parshad, R.; Sanford, K.K.; Jones, G.M.


    The authors reported previously that human cells after neoplastic transformation in culture had acquired an increased susceptibility to chromatid damage induced by x-irradiation during the G2 phase of the cell cycle. Evidence suggested that this results from deficient DNA repair during G2 phase. Cells derived from human tumors also showed enhanced G2-phase chromosomal radiosensitivity. Furthermore, skin fibroblasts from individuals with genetic diseases predisposing to a high risk of cancer, including ataxia-telangiectasia, Bloom syndrome, Fanconi anemia, and xeroderma pigmentosum exhibited enhanced G2-phase chromosomal radiosensitivity. The present study shows that apparently normal skin fibroblasts from individuals with familial cancer--i.e., from families with a history of neoplastic disease--also exhibit enhanced G2-phase chromosomal radiosensitivity. This radiosensitivity appears, therefore, to be associated with both a genetic predisposition to cancer and a malignant neoplastic state. Furthermore, enhanced G2-phase chromosomal radiosensitivity may provide the basis for an assay to detect genetic susceptibility to cancer

  16. Genetic evidence for a family-based Scandinavian settlement of Shetland and Orkney during the Viking periods. (United States)

    Goodacre, S; Helgason, A; Nicholson, J; Southam, L; Ferguson, L; Hickey, E; Vega, E; Stefánsson, K; Ward, R; Sykes, B


    The Viking age witnessed the expansion of Scandinavian invaders across much of northwestern Europe. While Scandinavian settlements had an enduring cultural impact on North Atlantic populations, the nature and extent of their genetic legacy in places such as Shetland and Orkney is not clear. In order to explore this question further, we have made an extensive survey of both Y-chromosomal and mitochondrial DNA (mtDNA) variation in the North Atlantic region. Our findings indicate an overall Scandinavian ancestry of approximately 44% for Shetland and approximately 30% for Orkney, with approximately equal contributions from Scandinavian male and female subjects in both cases. This contrasts with the situation for the Western Isles, where the overall Scandinavian ancestry is less ( approximately 15%) and where there is a disproportionately high contribution from Scandinavian males. In line with previous studies, we find that Iceland exhibits both the greatest overall amount of Scandinavian ancestry (55%) and the greatest discrepancy between Scandinavian male and female components. Our results suggest that while areas close to Scandinavia, such as Orkney and Shetland, may have been settled primarily by Scandinavian family groups, lone Scandinavian males, who later established families with female subjects from the British Isles, may have been prominent in areas more distant from their homeland.

    Pangaribuan, Rosnani; Scherbaum, Veronika; Erhardt, Jürgen G; Sastroamidjojo, Soemilah; Biesalski, Hans K


    The adherence of program participants to periodic vitamin A capsule (VAC) supplementation among children aged 1-5 years (n = 677) in Central Java, Indonesia was assessed. Fourteen villages from five sub-districts and one ward from one sub-district in Central Java were included in the study to represent rural and suburban areas. All questions about demographic factors, socioeconomic conditions, current dietary practice and healthcare-seeking attitudes for common childhood illnesses, previous breastfeeding experience, their knowledge about vitamin A and adherence to the VAC program after capsule distribution (two periods in 2000) were asked. Caretakers with limited knowledge about the health benefits of vitamin A, households with more than one preschool child, and households with older children (> 36 months) were associated with a decreased likelihood of regular participation in the program with odds ratios of 0.38, 0.55, and 0.26, respectively (p program regularly with an odds ratio of 2.02 (p program.

  18. For better or worse: Factors predicting outcomes of family care of older people over a one-year period. A six-country European study (United States)

    Bien, Barbara; McKee, Kevin; Krevers, Barbro; Mestheneos, Elizabeth; Di Rosa, Mirko; von dem Knesebeck, Olaf; Kofahl, Christopher


    Objectives Demographic change has led to an increase of older people in need of long-term care in nearly all European countries. Informal carers primarily provide the care and support needed by dependent people. The supply and willingness of individuals to act as carers are critical to sustain informal care resources as part of the home health care provision. This paper describes a longitudinal study of informal care in six European countries and reports analyses that determine those factors predicting the outcomes of family care over a one-year period. Methods Analyses are based on data from the EUROFAMCARE project, a longitudinal survey study of family carers of older people with baseline data collection in 2004 and follow-up data collection a year later in six European countries (Germany, Greece, Italy, Poland, Sweden, and the United Kingdom), N = 3,348. Descriptive statistics of the sample characteristics are reported. Binary logistic random-intercept regressions were computed, predicting the outcome of change of the care dyad’s status at follow-up. Results Where care is provided by a more distant family member or by a friend or neighbour, the care-recipient is significantly more likely to be cared for by someone else (OR 1.62) or to be in residential care (OR 3.37) after one year. The same holds true if the care-recipient has memory problems with a dementia diagnosis (OR 1.79/OR 1.84). Higher dependency (OR 1.22) and behavioural problems (OR 1.76) in the care-recipient also lead to a change of care dyad status. Country of residence explained a relatively small amount of variance (8%) in whether a care-recipient was cared for by someone else after one year, but explained a substantial amount of variance (52%) in whether a care-recipient was in residential care. Particularly in Sweden, care-recipients are much more likely to be cared for by another family or professional carer or to be in residential care, whereas in Greece the status of the care dyad is much

    To investigate parents' experiences, coping ability and quality of life while monitoring their sick child with hypoplastic left heart syndrome at home. Interstage home monitoring for children with hypoplastic left heart syndrome reduces interstage mortality between Norwood stages I and II. Little is known about the psychosocial impact of interstage home monitoring. Prospective mixed-method study. This study assessed the psychosocial impact on parents during interstage home monitoring. This contains for quantitative assessment the Short Form Health Survey questionnaire and the Impact of Family Scale administered one and five weeks following discharge before and after stage II. For qualitative assessment, semi-structured interviews focussing on the postdischarge coping strategies were conducted twice, five weeks after hospital discharge before and after stage II. Ten infants (eight males) with hypoplastic left heart syndrome (n = 7) or other types of univentricular heart malformations (n = 3), and their parents (nine mother/father two-parent households, one single mother) were included. There were no interstage deaths. Mental Health Composite Summary scores were low in both parents (mothers: 40·45 ± 9·07; fathers: 40·58 ± 9·69) and lowest for the item 'vitality' (mothers: 37·0 ± 19·46; fathers: 43·12 ± 25·9) before and after stage II. Impact of Family Scale values showed higher daily and social burdens for mothers. 'Becoming a family' was the most important task as coping strategy to equilibrate the fragile emotional balance. The parents judged interstage home monitoring as a protective intervention. Although psychosocial burden before and after stage II remains high, becoming a family is an essential experience for parents and confirms their parenthood. Healthcare professionals must be aware of parents' needs during this vulnerable interstage period and to provide psychosocial and nursing support. © 2016 John Wiley & Sons Ltd.

  1. On a family of KP multi-line solitons associated to rational degenerations of real hyperelliptic curves and to the finite non-periodic Toda hierarchy (United States)

    Abenda, Simonetta


    We continue the program started in Abenda and Grinevich (2015) of associating rational degenerations of M-curves to points in GrTNN(k , n) using KP theory for real finite gap solutions. More precisely, we focus on the inverse problem of characterizing the soliton data which produce Krichever divisors compatible with the KP reality condition when Γ is a certain rational degeneration of a hyperelliptic M-curve. Such choice is motivated by the fact that Γ is related to the curves associated to points in GrTP(1 , n) and in GrTP(n - 1 , n) in Abenda and Grinevich (2015). We prove that the reality condition on the Krichever divisor on Γ singles out a special family of KP multi-line solitons (T-hyperelliptic solitons) in GrTP(k , n) , k ∈ [ n - 1 ] , naturally connected to the finite non-periodic Toda hierarchy. We discuss the relations between the algebraic-geometric description of KP T-hyperelliptic solitons and of the open Toda system. Finally, we also explain the effect of the space-time transformation which conjugates soliton data in GrTP(k , n) to soliton data in GrTP(n - k , n) on the Krichever divisor for such KP solitons.

  3. Return to sexual activity and modern family planning use in the extended postpartum period: an analysis of findings from seventeen countries. (United States)

    Borda, Maria R; Winfrey, William; McKaig, Catharine


    Unintended pregnancies can lead to poor maternal and child health outcomes. Family planning use during the first year postpartum has the potential to significantly reduce at least some of these unintended pregnancies. This paper examines the relationship of menses return, breastfeeding status, and postpartum duration on return to sexual activity and use of modern family planning among postpartum women. This paper presents results from a secondary data analysis of Demographic and Health Surveys from 17 countries. For postpartum women, the return of menses, breastfeeding status, and postpartum duration are significantly associated with return to sexual activity in at least 10 out of the 17 countries but not consistently associated with family planning use. Only menses return had a significant association with use of modern family planning in the majority of countries. These findings point to the importance of education about pregnancy risk prior to menses return.

  4. State of the art in educational journals on studies of families of children with special educational needs in the period from 2002 to 2011

    Full Text Available The purpose of this paper is mapping studies indexed between the years of 2002 and 2011 in the educational field and evaluated like A1 or A2 by the database Qualis Capes, in the three years 2010-2012, in order to research ways that studies with families of children with special educational needs have been made. For this, we analyze elements such as: annual evolution of the studies, subjects analyzed, adopted and thematic instruments used to collect data from database searches “Scielo” and “Capes Journal” and a multitude of descriptors combined. The criterion for considering the family was that the research should contain the following keywords: family, family relationships, parental relationships, parents and siblings crisscrossing: special education, people with special educational needs, inclusive education, inclusion, autism, autistic, gifted, high ability, cerebral palsy, low vision, blindness, deafness, pervasive developmental disorder, Down Syndrome, disability, intellectual disability, physical disability, visual impairment, hearing impairment and multiple disabilities. Thus, the papers were obtained by intercrossing these descriptors, but it was selected those containing one of these words. With this, we found a total of 36 papers in national journals indexed in the area of Education. The data showed that there was a growing body of empirical research in this area.

  5. The impact of child and family stressors on the self-rated health of mothers of children with autism spectrum disorder: Associations with depressed mood over a 12-year period. (United States)

    Benson, Paul R


    Employing a cohort sequential design and multilevel modeling, the effects of child and family stressors and maternal depressed mood on the self-rated health of 110 mothers of children with autism spectrum disorder were assessed over a 12-year period when children in the study were 7-19 years old. Findings indicate a significant decline in self-rated health over time. In addition, child and family stressors, as well as maternal depressed mood, exerted significant between-persons effects on self-rated health such that mothers who reported more stressors and depressed mood across the study period were less likely to rate themselves in better health across that period. In addition, a significant within-person relationship between maternal depressed mood and self-rated health was found, indicating that at times when mothers reported higher levels of depressed mood than usual (their personal average across the study), they were significantly less likely to report better self-rated health. Finally, maternal depressed mood partially mediated the between-persons effects of child and family stressors on self-rated health such that increased stressors led to increased maternal depressed mood which, in turn, led to poorer maternal self-rated health. Findings suggest that chronic stressors erode maternal health over time and that depression may be an important mechanism linking stressors to decreased maternal health.

    Full Text Available La parálisis periódica hipocalémica familiar es una enfermedad que pertenece al grupo de las canalopatías. Consiste en la presentación de episodios de parálisis muscular progresivos en intensidad y frecuencia acompañada de hipocalemia. dos mutaciones explican la presencia de la enfermedad, la CACNA1S y la SCN4A, que afectan los canales de potasio mediados por calcio y los canales de sodio, respectivamente. Lo anterior repercute en la función de los canales para el potasio mediados por voltaje, llevando a una hipocalemia extracelular sostenida produciendo despolarización continua con parálisis. Los desencadenantes son el ejercicio, los carbohidratos, el frío, el estrés, entre otros, y las pruebas de provocación clínica se realizan con insulina, glucosa y ejercicio. La enfermedad se puede prevenir evitando estos factores y tiene alguna respuesta al tratamiento con acetazolamida. Se presenta el caso clínico de un niño que cumple con los criterios clínicos de paresia asociada a hipocalemia desencadenada por carbohidratos. Periodic hypokalemic familial paralysis (PHFP is a channel-mediated disease. Increasing focal or generalized muscular paralytic episodes are associated with low serum potassium levels. Two point mutations are described, CACNA1S and SCN4A. These mutations affect calcium and sodium mediated potassium channels. A continuous depolarization with low extracelular potassium promotes hypotonia. Known stressors are excercise, cold, stress and high carbohydrate intake. Control of stressors and azetazolamyde are the main treatment options. We describe one patient with clinical and laboratory characteristics of PHFP.

    Period mappings were introduced in the sixties [4] to study variation of complex structures of families of algebraic varieties. The theory of tautological systems was introduced recently [7,8] to understand period integrals of algebraic manifolds. In this paper, we give an explicit construction of a tautological system for each component of a period mapping. We also show that the D-module associated with the tautological system gives rise to many interesting vanishing conditions for period integrals at certain special points of the parameter space.

  18. The effect of community maternal and newborn health family meetings on type of birth attendant and completeness of maternal and newborn care received during birth and the early postnatal period in rural Ethiopia. (United States)

    Barry, Danika; Frew, Aynalem Hailemichael; Mohammed, Hajira; Desta, Binyam Fekadu; Tadesse, Lelisse; Aklilu, Yeshiwork; Biadgo, Abera; Buffington, Sandra Tebben; Sibley, Lynn M


    Maternal and newborn deaths occur predominantly in low-resource settings. Community-based packages of evidence-based interventions and skilled birth attendance can reduce these deaths. The Maternal and Newborn Health in Ethiopia Partnership (MaNHEP) used community-level health workers to conduct prenatal Community Maternal and Newborn Health family meetings to build skills and care-seeking behaviors among pregnant women and family caregivers. Baseline and endline surveys provided data on a random sample of women with a birth in the prior year. An intention-to-treat analysis, plausible net effect calculation, and dose-response analysis examined increases in completeness of care (mean percentage of 17 maternal and newborn health care elements performed) over time and by meeting participation. Regression models assessed the relationship between meeting participation, completeness of care, and use of skilled providers or health extension workers for birth care-controlling for sociodemographic and health service utilization factors. A 151% increase in care completeness occurred from baseline to endline. At endline, women who participated in 2 or more meetings had more complete care than women who participated in fewer than 2 meetings (89% vs 76% of care elements; P care completeness (P care were nearly 3 times more likely to have used a skilled provider or health extension worker for birth care. Women who had additionally attended 2 or more meetings with family members were over 5 times as likely to have used these providers, compared to women without antenatal care and who attended fewer than 2 meetings (odds ratio, 5.19; 95% confidence interval, 2.88-9.36; P care by engaging women and family caregivers in self-care and care-seeking, resulting in greater completeness of care and more highly skilled birth care. © 2014 by the American College of Nurse-Midwives.

    Objective: To analyze the clinical syndromes and inheritance patterns of multiplex families with epilepsy toward the ultimate aim of uncovering the underlying molecular genetic basis. Methods: Following the referral of families with 2 or more relatives with epilepsy, individuals were classified into epilepsy syndromes. Families were classified into syndromes where at least 2 family members had a specific diagnosis. Pedigrees were analyzed and molecular genetic studies were performed as appropriate. Results: A total of 211 families were ascertained over an 11-year period in Israel. A total of 169 were classified into broad familial epilepsy syndrome groups: 61 generalized, 22 focal, 24 febrile seizure syndromes, 33 special syndromes, and 29 mixed. A total of 42 families remained unclassified. Pathogenic variants were identified in 49/211 families (23%). The majority were found in established epilepsy genes (e.g., SCN1A, KCNQ2, CSTB), but in 11 families, this cohort contributed to the initial discovery (e.g., KCNT1, PCDH19, TBC1D24). We expand the phenotypic spectrum of established epilepsy genes by reporting a familial LAMC3 homozygous variant, where the predominant phenotype was epilepsy with myoclonic-atonic seizures, and a pathogenic SCN1A variant in a family where in 5 siblings the phenotype was broadly consistent with Dravet syndrome, a disorder that usually occurs sporadically. Conclusion: A total of 80% of families were successfully classified, with pathogenic variants identified in 23%. The successful characterization of familial electroclinical and inheritance patterns has highlighted the value of studying multiplex families and their contribution towards uncovering the genetic basis of the epilepsies.

  2. Detecting periodicities with Gaussian processes

    Directory of Open Access Journals (Sweden)

    Nicolas Durrande


    Full Text Available We consider the problem of detecting and quantifying the periodic component of a function given noise-corrupted observations of a limited number of input/output tuples. Our approach is based on Gaussian process regression, which provides a flexible non-parametric framework for modelling periodic data. We introduce a novel decomposition of the covariance function as the sum of periodic and aperiodic kernels. This decomposition allows for the creation of sub-models which capture the periodic nature of the signal and its complement. To quantify the periodicity of the signal, we derive a periodicity ratio which reflects the uncertainty in the fitted sub-models. Although the method can be applied to many kernels, we give a special emphasis to the Matérn family, from the expression of the reproducing kernel Hilbert space inner product to the implementation of the associated periodic kernels in a Gaussian process toolkit. The proposed method is illustrated by considering the detection of periodically expressed genes in the arabidopsis genome.

    Full Text Available AIM: The aim of the present study is to investigate the effect of the education and observation of supporting breast-feeding programme that is applied by family health staff on the mother’s of the post-birth period. METHOD: This research was conducted at a Family Health Center in Adiyaman between October 2008 and December 2009. Experimentally designed, study composed of 94 (42 experimental group, 52 control group volunteer mothers with babies who have not any health problems. At the beginning of study babies less than 6 months years old were taken into control group and questionnaire was applied to mothers after 6 months. Forty two babies born after completion of control group were taken into study group and a training programme on mother milk and breast-feeding was applied by family health staff to mothers in the first week of post-birth period and mothers were followed and motivated monthly. Data collected by questionnaire at the end of six months were analyzed by the independent sample t test, chi-square and percentage using SPSS (11.0 and p<0.05 was considered significant. RESULTS: The difference between experimental and control group were not statistically significant with regard to mother’s mean age, duration of marriage, pregnancy, childbirth, number of living children and economic status (p<0.05. The duration of breast-feeding alone was longer in study group than in control group (t=-6.888, p<0.001. CONCLUSION: It is concluded that the training and follow-up of mothers about breast feeding by Family Health staff’s positively influenced mothers’ behaviors on breast-feeding period, breast feeding alone and effective breast-feeding.

  5. Evolution of periodicity in periodical cicadas. (United States)

    Ito, Hiromu; Kakishima, Satoshi; Uehara, Takashi; Morita, Satoru; Koyama, Takuya; Sota, Teiji; Cooley, John R; Yoshimura, Jin


    Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors.

  6. Extended family medicine training (United States)

    Slade, Steve; Ross, Shelley; Lawrence, Kathrine; Archibald, Douglas; Mackay, Maria Palacios; Oandasan, Ivy F.


    Abstract Objective To examine trends in family medicine training at a time when substantial pedagogic change is under way, focusing on factors that relate to extended family medicine training. Design Aggregate-level secondary data analysis based on the Canadian Post-MD Education Registry. Setting Canada. Participants All Canadian citizens and permanent residents who were registered in postgraduate family medicine training programs within Canadian faculties of medicine from 1995 to 2013. Main outcome measures Number and proportion of family medicine residents exiting 2-year and extended (third-year and above) family medicine training programs, as well as the types and numbers of extended training programs offered in 2015. Results The proportion of family medicine trainees pursuing extended training almost doubled during the study period, going from 10.9% in 1995 to 21.1% in 2013. Men and Canadian medical graduates were more likely to take extended family medicine training. Among the 5 most recent family medicine exit cohorts (from 2009 to 2013), 25.9% of men completed extended training programs compared with 18.3% of women, and 23.1% of Canadian medical graduates completed extended training compared with 13.6% of international medical graduates. Family medicine programs vary substantially with respect to the proportion of their trainees who undertake extended training, ranging from a low of 12.3% to a high of 35.1% among trainees exiting from 2011 to 2013. Conclusion New initiatives, such as the Triple C Competency-based Curriculum, CanMEDS–Family Medicine, and Certificates of Added Competence, have emerged as part of family medicine education and credentialing. In acknowledgment of the potential effect of these initiatives, it is important that future research examine how pedagogic change and, in particular, extended training shapes the care family physicians offer their patients. As part of that research it will be important to measure the breadth and uptake of

    The acronym IDEALS summarizes family physicians' obligations when violence is suspected: to identify family violence; document injuries; educate families and ensure safety for victims; access resources and coordinate care; co-operate in the legal process; and provide support for families. Failure to respond reflects personal and professional experience and attitudes, fear of legal involvement, and lack of knowledge. Risks of intervention include physician burnout, physician overfunctioning, escalation of violence, and family disruption. PMID:21228987

  8. Family caring strategies in neutropenia. (United States)

    Eggenberger, Sandra K; Krumwiede, Norma; Meiers, Sonja J; Bliesmer, Mary; Earle, Patricia


    Aggressive chemotherapy protocols result in neutropenia in approximately half of all patients receiving chemotherapy. Thus, neutropenia continues to be a significant and potentially life-threatening side effect of treatment, even with use of colony-stimulating factors. Families of patients with neutropenia often provide the primary healing environment because most chemotherapy protocols are managed on an outpatient basis. To learn about the family's experience of managing chemotherapy-induced neutropenia (CIN), a grounded-theory methodology was used to analyze data from seven families. The central theme revealed by these families was "turbulent waiting with intensified connections." This meant that when families had a sense of greater vulnerability in response to the waiting after diagnosis of CIN, they connected intensely with each other and healthcare providers. Families reported that connections with nurses became more significant when neutropenia interrupted chemotherapy. Families also developed family caring strategies to manage this period of waiting for the chemotherapy to resume. These strategies included family inquiry, family vigilance, and family balancing. Nurses need to be aware of approaches to support the family's ability to manage CIN. Interventions and approaches constructed from the perspective of a family-professional partnership will enhance the family cancer experience as well as ongoing family growth and function.

  15. Jamaican families. (United States)

    Miner, Dianne Cooney


    The study of the family in the Caribbean originated with European scholars who assumed the universality of the patriarchal nuclear family and the primacy of this structure to the healthy functioning of society. Matrifocal Caribbean families thus were seen as chaotic and disorganized and inadequate to perform the essential tasks of the social system. This article provides a more current discussion of the Jamaican family. It argues that its structure is the result of the agency and adaptation of its members and not the root cause of the increasing marginalization of peoples in the developing world. The article focuses on families living in poverty and how the family structure supports essential family functions, adaptations, and survival.

  16. Periodic and quasiperiodic revivals in periodically driven interacting quantum systems (United States)

    Luitz, David J.; Lazarides, Achilleas; Bar Lev, Yevgeny


    Recently it has been shown that interparticle interactions generically destroy dynamical localization in periodically driven systems, resulting in diffusive transport and heating. In this Rapid Communication we rigorously construct a family of interacting driven systems which are dynamically localized and effectively decoupled from the external driving potential. We show that these systems exhibit tunable periodic or quasiperiodic revivals of the many-body wave function and thus of all physical observables. By numerically examining spinless fermions on a one-dimensional lattice we show that the analytically obtained revivals of such systems remain stable for finite systems with open boundary conditions while having a finite lifetime in the presence of static spatial disorder. We find this lifetime to be inversely proportional to the disorder strength.

  8. Study of a family that overcomes poverty issues: family resilience?

    Directory of Open Access Journals (Sweden)

    María Ángela Mattar Yunes


    Full Text Available Generally, researches with families focus the difficulties and the negative aspects of family life by bringing up their maladjustments and failures. The interest in family resilience contributes to change this logic by demonstrating the healthy aspects of the family world. Nevertheless, the term resilience presents ideological controversies which are more severe when the discussion is about families and poverty. In order to diminish these contradictions this study adopted a systemic concept of resilience which refers to “those processes that make possible to overcome adversities”. A case study was realized with a low income family who lived in a “very poor” neighborhood in the deep south of Brazil. The methodological strategies to the formal investigation of the family were: life history of the family using the principles of reflexive interview, genograms and data analyses through the approach of the grounded theory. The results showed that the family lived a number of risk experiences such as adoption, privation of basic needs, migration and diseases. Among the indicators of their abilities of “overcoming adversities”, emerged the belief system as the core of the discourses. The family showed that they value the interpersonal relationships through intra and extra familiar interactions based in the patterns of help, learning, affection and solidarity. During the crisis the family gives meaning to the difficulties in order to maintaining the situation controlled through cohesion, open communication, mutual respect and getting support of the extended family/ social network. The pos-adversity period is perceived as benefic and transforming as the family feels stronger and with feelings of solidarity, which is a mark of this family. Their attitude in relation to the neighborhood is active in the sense of promoting the welfare of other families who live in the same social address. Would those above identified processes be adequate to

  9. Do family CEOs impact firm value? An empirical analysis of Indian family firms

    Directory of Open Access Journals (Sweden)

    Lakshmi Kalyanaraman


    Full Text Available We study the association between family CEO and firm value on a sample of 288 family firms during the 6-year period, from 2009 to 2014. The sample is drawn from domestic private companies belonging to non-financial services sector included in the NSE CNX 500 index. We find that family CEO has no significant association with firm value, when the family is not the majority shareholder. Family shareholding has positive relationship with firm value, but does not moderate the relationship of family CEO with firm value. We show that family CEO and firm value are negatively related when the family does not hold majority equity stake in the family firm. While family shareholding has no significant relationship with firm value, it has a negative interaction effect on the relationship between family CEO and firm value. The research findings have important implications for family firms as well as the nonfamily investors in the family firms.

  10. Autoinflammatory Diseases with Periodic Fevers. (United States)

    Sag, Erdal; Bilginer, Yelda; Ozen, Seza


    One purpose of this review was to raise awareness for the new autoinflammatory syndromes. These diseases are increasingly recognized and are in the differential diagnosis of many disease states. We also aimed to review the latest recommendations for the diagnosis, management, and treatment of these patients. Familial Mediterranean fever (FMF), cryopyrin-associated periodic syndrome (CAPS), tumor necrosis factor receptor-associated periodic fever syndrome (TRAPS), and hyperimmunoglobulinemia D and periodic fever syndrome/mevalonate kinase deficiency (HIDS/MVKD) are the more common autoinflammatory diseases that are characterized by periodic fevers and attacks of inflammation. Recently much collaborative work has been done to understand the characteristics of these patients and to develop recommendations to guide the physicians in the care of these patients. These recent recommendations will be summarized for all four diseases. FMF is the most common periodic fever disease. We need to further understand the pathogenesis and the role of single mutations in the disease. Recently, the management and treatment of the disease have been nicely reviewed. CAPS is another interesting disease associated with severe complications. Anti-interleukin-1 (anti-IL-1) treatment provides cure for these patients. TRAPS is characterized by the longest delay in diagnosis; thus, both pediatricians and internists should be aware of the characteristic features and the follow-up of these patients. HIDS/MVKD is another autoinflammatory diseases characterized with fever attacks. The spectrum of disease manifestation is rather large in this disease, and we need further research on biomarkers for the optimal management of these patients.

  20. Periods and Nori motives

    CERN Document Server

    Huber, Annette


    This book casts the theory of periods of algebraic varieties in the natural setting of Madhav Nori’s abelian category of mixed motives. It develops Nori’s approach to mixed motives from scratch, thereby filling an important gap in the literature, and then explains the connection of mixed motives to periods, including a detailed account of the theory of period numbers in the sense of Kontsevich-Zagier and their structural properties. Period numbers are central to number theory and algebraic geometry, and also play an important role in other fields such as mathematical physics. There are long-standing conjectures about their transcendence properties, best understood in the language of cohomology of algebraic varieties or, more generally, motives. Readers of this book will discover that Nori’s unconditional construction of an abelian category of motives (over fields embeddable into the complex numbers) is particularly well suited for this purpose. Notably, Kontsevich's formal period algebra represents a to...

  1. Family welfare. (United States)

    Sinha, N K


    Between 1901-1921, India gained 12.9 million people because mortality remained high. The death rate fell between 1921-1951, but birth rates remained the same. Therefore 110 million people were added--2 times the population increase between 1891-1921. Between 1951-1981, the population increased to 324 million. Socioeconomic development was responsible for most of the downward trend in the birth rate during the 20th century. Even though large families were the norm in early India, religious leaders encouraged small family size. The 1st government family planning clinics in the world opened in Mysore and Bangalore in 1930. Right before Independence, the Bhore Committee made recommendations to reduce population growth such as increasing the age of marriage for girls. Since 1951 there has been a change in measures and policies geared towards population growth with each of the 7 5-Year Plans because policy makers applied what they learned from each previous plan. The 1st 5-Year Plan emphasized the need to understand what factors contribute to population growth. It also integrated family planning services into health services of hospitals and health centers. The government was over zealous in its implementation of the sterilization program (2nd 5-Year Plan, 1956-1961), however, which hurt family planning programs for many years. As of early 1992, sterilization, especially tubectomy, remained the most popular family planning method, however. The 7th 5-Year Plan changed its target of reaching a Net Reproductive Rate of 1 by 2001 to 2006-2011. It set a goal of 100% immunization coverage by 1990 but it did not occur. In 1986, the Ministry of Health and Family Welfare planned to make free contraceptives available in urban and rural areas and to involve voluntary organizations. The government needs to instill measures to increase women's status, women's literacy, and age of marriage as well as to eliminate poverty, ensure old age security, and ensure child survival and

    Full Text Available We show that any mean-periodic function f can be represented in terms of exponential-polynomial solutions of the same convolution equation f satisfies, i.e., u∗f=0(μ∈E′(ℝn. This extends to n-variables the work of L. Schwartz on mean-periodicity and also extends L. Ehrenpreis' work on partial differential equations with constant coefficients to arbitrary convolutors. We also answer a number of open questions about mean-periodic functions of one variable. The basic ingredient is our work on interpolation by entire functions in one and several complex variables.

  3. Familial macrocephaly

    International Nuclear Information System (INIS)

    Tatsuno, Masaru; Hayashi, Michiko; Iwamoto, Hiroko


    We reported 63 macrocephalic children with special emphasis on 16 cases with familial macrocephaly. Of the 16 children with familial macrocephaly, 13 were boys. Foureen parents (13 fathers and 1 mother) had head sizes above 98th percentile. Three of 5 brothers and 5 of 8 sisters also had large heads. The head circumference at birth was known for 14 of the children and it was above the 98th percentile in 7 patients. Subsequent evaluations have shown the head size of these children to be following a normal growth curve. Some of the children were hypotonic as infants, but their development was generally normal. CT scans usually clearly distinguished these children from those with hydorocephalus. The familial macrocephalic children had ventricular measurements which were within the normal range, but absolute measurements of the ventricular size may be misleading, because the CT appearance was of mildly dilated ventricles in half of them.

  6. Super periodic potential (United States)

    Hasan, Mohammd; Mandal, Bhabani Prasad


    In this paper we introduce the concept of super periodic potential (SPP) of arbitrary order n, n ∈I+, in one dimension. General theory of wave propagation through SPP of order n is presented and the reflection and transmission coefficients are derived in their closed analytical form by transfer matrix formulation. We present scattering features of super periodic rectangular potential and super periodic delta potential as special cases of SPP. It is found that the symmetric self-similarity is the special case of super periodicity. Thus by identifying a symmetric fractal potential as special cases of SPP, one can obtain the tunnelling amplitude for a particle from such fractal potential. By using the formalism of SPP we obtain the close form expression of tunnelling amplitude of a particle for general Cantor and Smith-Volterra-Cantor potentials.

  10. Hypokalemic periodic paralysis: Three rare secondary causes

    Directory of Open Access Journals (Sweden)

    Prasanna Eswaradass Venkatesan


    Full Text Available Periodic paralysis is a rare neuromuscular disorder, related to a defect in muscle ion channels, characterized by episodes of painless muscle weakness, which may be precipitated by heavy exercise, fasting, or high-carbohydrate meals. Hypokalemic periodic paralysis may be familial (primary or secondary. Here, we report three cases of secondary causes of hypokalemic periodic paralysis. On evaluation, case 1 had distal renal tubular acidosis (RTA due to Sjogren′s syndrome, case 2 had drug induced proximal RTA (Fanconi′s syndrome and case 3 had thyrotoxicosis. Clinician must be aware of causes of secondary PP as recognition and diagnosis can completely prevent further attacks of periodic paralysis. Each of the above case is rare, but completely treatable if diagnosed. Low dose steroids with bicarbonate replacement in case 1, stopping tenofovir in case 2 and carbimazole therapy in case 3 prevented further attacks of periodic paralysis and cardiopulmonary complications.

    The higher order supersymmetric partners of a stationary periodic potential are studied. The transformation functions associated to the band edges do not change the spectral structure. However, when the transformation is implemented for factorization energies inside of the forbidden bands, the final potential will have again the initial band structure but it can have bound states encrusted into the gaps, giving place to localized periodicity defects.

    Following a recommendation by the International Union for Pure and Applied Chemistry (IUPAC), the groups of the periodic table shall be numbered from 1 to 18, instead of I to VIII as before. The recommendations has been approved of by the Committee on Nomenclature of the American Chemical Society. The new system abandons the distinction between main groups (a) and auxiliary groups (b), which in the past frequently has been the reason for misunderstandings between European and American chemists, due to different handling. The publishing house VCH Verlagsgesellschaft recently produced a new periodic table that shows the old and the new numbering system together at a glance, so that chemists will have time to get familiar with the new system. In addition the new periodic table represents an extensive data compilation arranged by elements. The front page lists the chemical properties of elements, the back page their physical properties.

    Rojith Karandode Balakrishnan


    Full Text Available This article aims at highlighting the importance of suspecting thyrotoxicosis in cases of recurrent periodic flaccid paralysis; especially in Asian men to facilitate early diagnosis of the former condition. A case report of a 28 year old male patient with recurrent periodic flaccid paralysis has been presented. Hypokalemia secondary to thyrotoxicosis was diagnosed as the cause of the paralysis. The patient was given oral potassium intervention over 24 hours. The patient showed complete recovery after the medical intervention and was discharged after 24 hours with no residual paralysis. Thyrotoxic periodic paralysis (TPP is a complication of thyrotoxicosis, more common amongst males in Asia. It presents as acute flaccid paralysis in a case of hyperthyroidism with associated hypokalemia. The features of thyrotoxicosis may be subtle or absent. Thus, in cases of recurrent or acute flaccid muscle paralysis, it is important to consider thyrotoxicosis as one of the possible causes, and take measures accordingly.

  3. [Family violence]. (United States)

    Manoudi, F; Chagh, R; Es-soussi, M; Asri, F; Tazi, I


    Family violence is a serious public health problem, the scale of which is seriously increasing in Morocco. Although it has existed for a long time, we ignore the real characteristics of this plague in our country; our work consisted in an epidemiological approach of family violence in Marrakech during 2006. After elaborating a questionnaire, which allows the study of the demographic and social profile of the families, the study of violence exercised in the family and the evaluation of the depression in the women, we led an inquiry amongst 265 women. Analysis of the results obtained has allowed us to underline the following characteristics: 16.6% of the women in our sample had been physically beaten; the young age is a risk factor; the age range most affected by violence is in women between the ages of 30 and 40 and which represent 39% of the battered women; domestic violence touches all the social, economic and cultural classes: in our study, 63% of the women having undergone violence were housewives, 25% were managers and 3% senior executives; family problems were the most important cause of violence in our study, representing 32.32%. Requests for money was the cause in 11.3% of the cases, and imposed sexual relations were found in 6.8% of the cases; alcoholism is an aggravating factor of family violence; 27.3% of the spouses who assaulted their wives were drunk; 52% of the assaulted women were victims of violence in childhood and 36% had been witness to their father's violence; in 63.6% of the cases of violence, the children were witnesses, and in 25% of the cases the children were victims of violence at the same time as their mothers; 50% of the women victims of violence did not react, while 38.6% left home, and 9.1 filed for divorce. Thirty-two percent of the assaulted woman had been traumatised by the aggression; the association of depression and violence was very high, 343% of the battered women in our study suffered from severe depression.

  4. Periodically poled silicon (United States)

    Hon, Nick K.; Tsia, Kevin K.; Solli, Daniel R.; Khurgin, Jacob B.; Jalali, Bahram


    Bulk centrosymmetric silicon lacks second-order optical nonlinearity χ(2) - a foundational component of nonlinear optics. Here, we propose a new class of photonic device which enables χ(2) as well as quasi-phase matching based on periodic stress fields in silicon - periodically-poled silicon (PePSi). This concept adds the periodic poling capability to silicon photonics, and allows the excellent crystal quality and advanced manufacturing capabilities of silicon to be harnessed for devices based on χ(2)) effects. The concept can also be simply achieved by having periodic arrangement of stressed thin films along a silicon waveguide. As an example of the utility, we present simulations showing that mid-wave infrared radiation can be efficiently generated through difference frequency generation from near-infrared with a conversion efficiency of 50% based on χ(2) values measurements for strained silicon reported in the literature [Jacobson et al. Nature 441, 199 (2006)]. The use of PePSi for frequency conversion can also be extended to terahertz generation. With integrated piezoelectric material, dynamically control of χ(2)nonlinearity in PePSi waveguide may also be achieved. The successful realization of PePSi based devices depends on the strength of the stress induced χ(2) in silicon. Presently, there exists a significant discrepancy in the literature between the theoretical and experimentally measured values. We present a simple theoretical model that produces result consistent with prior theoretical works and use this model to identify possible reasons for this discrepancy.

  7. Astrophysical implications of periodicity

    International Nuclear Information System (INIS)

    Muller, R.A.


    Two remarkable discoveries of the last decade have profound implications for astrophysics and for geophysics. These are the discovery by Alvarez et al., that certain mass extinctions are caused by the impact on the earth of a large asteroid or comet, and the discovery by Raup and Sepkoski that such extinctions are periodic, with a cycle time of 26 to 30 million years. The validity of both of these discoveries is assumed and the implications are examined. Most of the phenomena described depend not on periodicity, but just on the weaker assumption that the impacts on the earth take place primarily in showers. Proposed explanations for the periodicity include galactic oscillations, the Planet X model, and the possibility of Nemesis, a solar companion star. These hypotheses are critically examined. Results of the search for the solar companion are reported. The Deccan flood basalts of India have been proposed as the impact site for the Cretaceous impact, but this hypotheisis is in contradiction with the conclusion of Courtillot et al., that the magma flow began during a period of normal magnetic field. A possible resolution of this contradiction is proposed

  10. FAMILY BOMBYLIIDAE. (United States)

    Lamas, Carlos José Einicker; Evenhuis, Neal L


    Bombyliidae is one of the largest Diptera families with more than 4,500 recognized species worldwide. Their species vary from robust to thin, and may be small to large (2-20mm) and looks like bees or wasps. They also present great variation in color. Adults can often be seen either resting and sunning themselves on trails, rocks or twigs or feeding on flowering plants as they are nectar feeders. All reared bee flies are predators or parasitoids of arthropods. The Colombian fauna of bombyliids comprises at the moment 22 species, and 12 genera, of which, six are endemic species. Nonetheless, this number may be much higher, as Colombia is a megadiverse country and there are not many specimens of this family deposited in collections all over the world.

  11. Improving Family Communication. (United States)

    Medrano, Vilma; Bonilla, Gladys; Hernández, Ericka; Romanjek, Mariana Harnecker; Gómez, Adriana; Hernández, Jasón; Reyes, Marcela Ríos; Lindenberg, Cathy Strachan


    TeenSmart International harnesses the power and flexibility of technology to empower youth to take personal responsibility for their health and lifestyle choices. Access to the Internet via mobile phones is often cheaper than paying to connect to a wired broadband service, and in rural areas, mobile networks may be the only means of accessing the Internet. This study assessed the feasibility, acceptability, and impact of "cues to action" or brief motivating cell phone text messages to improve adolescent family communication and relationships. A quasi-experimental design using a voluntary sample of 100 Nicaraguan youth at high risk for poor family communication participated. Pre- and posttest quantitative measures using Student t statistical analysis, a focus group, and a participant testimony provided the evaluation evidence. Findings suggest that there are economic and motivational barriers to the use of text messages, but when barriers are eliminated, the behavioral results are positive. Youth who received two weekly text messages over a 6-month period demonstrated statistically significant improvements in family communication perceptions, attitudes, and behaviors, strengthening their family communications and relationships. Brief and personalized text messaging "cues to action" may be a cost-effective intervention to improve adolescent healthy lifestyle behaviors.

  12. Quantized gauge invariant periodic TDHF solutions

    International Nuclear Information System (INIS)

    Kan, K.-K.; Griffin, J.J.; Lichtner, P.C.; Dworzecka, M.


    Time-dependent Hartree-Fock (TDHF) is used to study steady state large amplitude nuclear collective motions, such as vibration and rotation. As is well known the small amplitude TDHF leads to the RPA equation. The analysis of periodicity in TDHF is not trivial because TDHF is a nonlinear theory and it is not known under what circumstances a nonlinear theory can support periodic solutions. It is also unknown whether such periodic solution, if they exist, form a continuous or a discrete set. But, these properties may be important in obtaining the energy spectrum of the collective states from the TDHF description. The periodicity and Gauge Invariant Periodicity of solutions are investigated for that class of models whose TDHF solutions depend on time through two parameters. In such models TDHF supports a continuous family of periodic solutions, but only a discrete subset of these is gauge invariant. These discrete Gauge Invariant Periodic solutions obey the Bohr-Summerfeld quantization rule. The energy spectrum of the Gauge Invariant Periodic solutions is compared with the exact eigenergies in one specific example

  13. Thyrotoxic periodic paralysis

    International Nuclear Information System (INIS)

    Ferreiro, J.E.; Arguelles, D.J.; Rams, H. Jr.


    A case of thyrotoxic periodic paralysis is reported in a Hispanic man with an unusual recurrence six weeks after radioactive iodine treatment. Thyrotoxic periodic paralysis has now been well characterized in the literature: it occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion, with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is establishing a euthyroid state. The pathophysiology is still controversial, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself

  14. Balancing Family and Career (United States)

    Andam, Aba Bentil; Dawson, Silvina Ponce; Horton, K. Renee; Sandow, Barbara


    In essentially all countries, responsibilities for child care, cooking, cleaning, and other homemaking tasks fall predominantly on the wife and mother. In addition, the childbearing years come during the period when a physicist must study hard, work long hours on research, and take temporary positions, often abroad. Thus, balancing family and career has long been one of the major barriers to women's participation in science and engineering fields, including physics. While many young women believe that they must choose between having children and having a science career, the fact is that the majority of women physicists in both developing and developed countries have successfully done both. This paper summarizes some ideas and recommendations raised in discussions, especially focused on easing the challenges of having children while in temporary jobs, returning to physics after a career break, the need for "family-friendly" working conditions, and the dual-career problem facing couples where both are scientists.

  15. Prenatal family support, postnatal family support and postpartum depression. (United States)

    Xie, Ri-Hua; Yang, Jianzhou; Liao, Shunping; Xie, Haiyan; Walker, Mark; Wen, Shi Wu


    Inadequate social support is an important determinant of postpartum depression (PPD). Social support for pregnant women consists of supports from various sources and can be measured at different gestation periods. Differentiating the effects of social support from different sources and measured at different gestation periods may have important implications in the prevention of PPD. In the family centred Chinese culture, family support is likely to be one of the most important components in social support. The aim of this study was to assess the association of prenatal family support and postnatal family support with PPD. A prospective cohort study was conducted between February and September 2007 in Hunan, China. Family support was measured with social support rating scale at 30-32 weeks of gestation (prenatal support) and again at 2 weeks of postpartum visit (postnatal support). PPD was defined as Edinburgh Postnatal Depression Scale (EPDS) score > or =13. A total of 534 pregnant women were included, and among them, 103 (19.3%) scored 13 or more on the EPDS. PPD was 19.4% in the lowest tertile versus 18.4% in the highest quartile (adjusted odds ratio: 1.04, 95% confidence interval 0.60, 1.80) for prenatal support from all family members, and PPD was 39.8% in the lowest tertile versus 9.6% in the highest tertile (adjusted odds ratio: 4.4, 95% confidence interval 2.3, 8.4) for postnatal support from all family members. Among family members, support from husband had the largest impact on the risk of developing PPD. Lack of postnatal family support, especially the support from husband, is an important risk factor of PPD.

    Separation of variables in the Helmholtz N-dimensional (N≥4) equation in polyspheroidal coordinate systems leads to the necessity of solving equations going over into equations for polyspheroidal periodic functions used for solving the two-centre problem in quantum mechanics, the three-body problem with Coulomb interaction, etc. For these functions the expansions are derived in terms of the Jacobi polynomials and Bessel functions. Their basic properties, asymptotics are considered. The algorithm of their computer calculations is developed. The results of numerical calculations are given

  20. Deciphering Periodic Methanol Masers (United States)

    Stecklum, Bringfried; Caratti o Garatti, Alessio; Henning, Thomas; Hodapp, Klaus; Hopp, Ulrich; Kraus, Alex; Linz, Hendrik; Sanna, Alberto; Sobolev, Andrej; Wolf, Verena


    Impressive progress has been made in recent years on massive star formation, yet the involved high optical depths even at submm/mm wavelengths make it difficult to reveal its details. Recently, accretion bursts of massive YSOs have been identified to cause flares of Class II methanol masers (methanol masers for short) due to enhanced mid-IR pumping. This opens a new window to protostellar accretion variability, and implies that periodic methanol masers hint at cyclic accretion. Pinning down the cause of the periodicity requires joint IR and radio monitoring. We derived the first IR light curve of a periodic maser host from NEOWISE data. The source, G107.298+5.639, is an intermediate-mass YSO hosting methanol and water masers which flare every 34.5 days. Our recent joint K-band and radio observations yielded first but marginal evidence for a phase lag between the rise of IR and maser emission, respectively, and revealed that both NEOWISE and K-band light curves are strongly affected by the light echo from the ambient dust. Both the superior resolution of IRAC over NEOWISE and the longer wavelengths compared to our ground-based imaging are required to inhibit the distractive contamination by the light echo. Thus, we ask for IRAC monitoring of G107 to cover one flare cycle, in tandem with 100-m Effelsberg and 2-m Wendelstein radio and NIR observations to obtain the first high-quality synoptic measurements of this kind of sources. The IR-maser phase lag, the intrinsic shape of the IR light curves and their possible color variation during the cycle allow us to constrain models for the periodic maser excitation. Since methanol masers are signposts of intermediate-mass and massive YSOs, deciphering their variability offers a clue to the dynamics of the accretion-mediated growth of massive stars and their feedback onto the immediate natal environment. The Spitzer light curve of such a maser-hosting YSO would be a legacy science product of the mission.

  2. Closed almost-periodic orbits in semiclassical quantization of generic polygons (United States)



    Periodic orbits are the central ingredients of modern semiclassical theories and corrections to these are generally nonclassical in origin. We show here that, for the class of generic polygonal billiards, the corrections are predominantly classical in origin owing to the contributions from closed almost-periodic (CAP) orbit families. Furthermore, CAP orbit families outnumber periodic families but have comparable weights. They are hence indispensable for semiclassical quantization.

  4. Periodically modulated dark states (United States)

    Han, Yingying; Zhang, Jun; Zhang, Wenxian


    Phenomena of electromagnetically induced transparency (PEIT) may be interpreted by the Autler-Townes Splitting (ATS), where the coupled states are split by the coupling laser field, or by the quantum destructive interference (QDI), where the atomic phases caused by the coupling laser and the probe laser field cancel. We propose modulated experiments to explore the PEIT in an alternative way by periodically modulating the coupling and the probe fields in a Λ-type three-level system initially in a dark state. Our analytical and numerical results rule out the ATS interpretation and show that the QDI interpretation is more appropriate for the modulated experiments. Interestingly, dark state persists in the double-modulation situation where control and probe fields never occur simultaneously, which is significant difference from the traditional dark state condition. The proposed experiments are readily implemented in atomic gases, artificial atoms in superconducting quantum devices, or three-level meta-atoms in meta-materials.

  5. Periodic trajectories for two-dimensional nonintegrable Hamiltonians

    Davies, K.T.R.


    I want to report on some calculations of classical periodic trajectories in a two-dimensional nonintegrable potential. After a brief introduction, I will present some details of the theory. The main part of this report will be devoted to showing pictures of the various families of trajectories and to discussing the topology (in E-τ space) and branching behavior of these families. Then I will demonstrate the connection between periodic trajectories and ''nearby'' nonperiodic trajectories, which nicely illustrates the relationship of this work to chaos. Finally, I will discuss very briefly how periodic trajectories can be used to calculate tori. 12 refs., 40 figs

    Full Text Available Hyperkalemia can present with a spectrum of clinical manifestations with progressive EKG changes and life-threatening arrhythmias. Although no formal guidelines exist as to when to initiate treatment for hyperkalemia, it is generally recommended in clinically symptomatic patients with or without EKG changes. Timely diagnosis and reversal can relieve symptoms and prevent life-threatening arrhythmias. We review the EKG changes associated with hyperkalemia and management principles along with an example of a case of severe hyperkalemia resulting in arrhythmia and flaccid paralysis.

  7. Hyperkalemic Cardioplegia for Adult and Pediatric Surgery: End of an Era?

    Directory of Open Access Journals (Sweden)

    Geoffrey Phillip Dobson


    Full Text Available Despite surgical proficiency and innovation driving low mortality rates in cardiac surgery, the disease severity, comorbidity rate and operative procedural difficulty have increased. Today’s cardiac surgery patient is older, has a sicker heart and often presents with multiple comorbidities; a scenario that was relatively rare 20 years ago. The global challenge has been to find new ways to make surgery safer for the patient and more predictable for the surgeon. A confounding factor that may influence clinical outcome is high K+ cardioplegia. For over 40 years, potassium depolarization has been linked to transmembrane ionic imbalances, arrhythmias and conduction disturbances, vasoconstriction, coronary spasm, contractile stunning, and low output syndrome. Other than inducing rapid electrochemical arrest, high K+ cardioplegia offers little or no inherent protection to adult or pediatric patients. This review provides a brief history of high K+ cardioplegia, five areas of increasing concern with prolonged membrane K+ depolarization, and the basic science and clinical data underpinning a new normokalemic, ‘polarizing’ cardioplegia comprising adenosine and lidocaine (AL with magnesium (Mg2+ (ALM. We argue that improved cardioprotection, better outcomes, faster recoveries and lower healthcare costs are achievable and, despite the early predictions from the stent industry and cardiology, the cath lab may not be the place where the new wave of high-risk morbid patients are best served.

  9. Strengthening Family Practices for Latino Families. (United States)

    Chartier, Karen G; Negroni, Lirio K; Hesselbrock, Michie N


    The study examined the effectiveness of a culturally-adapted Strengthening Families Program (SFP) for Latinos to reduce risks for alcohol and drug use in children. Latino families, predominantly Puerto Rican, with a 9-12 year old child and a parent(s) with a substance abuse problem participated in the study. Pre- and post-tests were conducted with each family. Parental stress, parent-child dysfunctional relations, and child behavior problems were reduced in the families receiving the intervention; family hardiness and family attachment were improved. Findings contribute to the validation of the SFP with Latinos, and can be used to inform social work practice with Puerto Rican families.

  10. [Childhood periodic syndromes]. (United States)

    Cuvellier, J-C; Lépine, A


    This review focuses on the so-called "periodic syndromes of childhood that are precursors to migraine", as included in the Second Edition of the International Classification of Headache Disorders. Three periodic syndromes of childhood are included in the Second Edition of the International Classification of Headache Disorders: abdominal migraine, cyclic vomiting syndrome and benign paroxysmal vertigo, and a fourth, benign paroxysmal torticollis is presented in the Appendix. The key clinical features of this group of disorders are the episodic pattern and intervals of complete health. Episodes of benign paroxysmal torticollis begin between 2 and 8 months of age. Attacks are characterized by an abnormal inclination and/or rotation of the head to one side, due to cervical dystonia. They usually resolve by 5 years. Benign paroxysmal vertigo presents as sudden attacks of vertigo, accompanied by inability to stand without support, and lasting seconds to minutes. Age at onset is between 2 and 4 years, and the symptoms disappear by the age of 5. Cyclic vomiting syndrome is characterized in young infants and children by repeated stereotyped episodes of pernicious vomiting, at times to the point of dehydration, and impacting quality of life. Mean age of onset is 5 years. Abdominal migraine remains a controversial issue and presents in childhood with repeated stereotyped episodes of unexplained abdominal pain, nausea and vomiting occurring in the absence of headache. Mean age of onset is 7 years. Both cyclic vomiting syndrome and abdominal migraine are noted for the absence of pathognomonic clinical features but also for the large number of other conditions to be considered in their differential diagnoses. Diagnostic criteria, such as those of the Second Edition of the International Classification of Headache Disorders and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition, have made diagnostic approach and management easier.

  16. Periodic orbits near the particle resonance in galaxies

    CERN Document Server

    Contopoulos, George


    Near the particle resonance of a spiral galaxy the almost circular periodic orbits that exist inside the resonance (direct) or outside it (retrograde) are replaced by elongated trapped orbits around the maxima of the potential L/sub 4/ and L/sub 5/. These are the long- period trapped periodic orbits. The long-period orbits shrink to the points L/sub 4/, L/sub 5/ for a critical value of the Hamiltonian h. For still larger h, a family of short-period trapped orbits appears, with continuously growing size. The evolution of the periodic orbits with h is followed, theoretically and numerically, from the untrapped orbits to the long-periodic orbits and then to the short-periodic orbits, mainly in the case of a bar. In a tight spiral case an explanation of the asymmetric periodic and banana orbits is given, and an example of short-period orbits not surrounding L/sub 4/ or L/sub 5/ is provided. Another family of periodic orbits reaching corotation is trapped at the inner Lindblad resonance. (5 refs).

  17. Correlation between family interaction and adolescents’ attitudes

    Directory of Open Access Journals (Sweden)

    Rozana Petani


    Full Text Available The impact of the family on the individual is very powerful and life-long. The family differs from other factors because the individual spends the most time in the family environment. In his family the child makes his first steps, utters the first words, starts gaining knowledge, learns his first value, forms attitudes and forms the foundation for the later development as a complete personality. Parents are the first and most responsible educators of their child, and upbringing is the most important and probably the hardest task of every parent. The period of adolescence is very important in every person’s life, especially because of the process of separation and individuation. This is a transitional period from childhood to maturity with the greatest dynamics in the development of the individual. In this period adolescents change and mature. They are able to make independent decisions. Relationships with their parents play an important role in shaping their behavior. The paper observes the family through family interaction, which consists of the following dimensions: satisfaction with their own families, acceptance and rejection by the mother and father. The aim of this study was to examine whether dimensions of parental behavior and satisfaction with their own families, perceived by adolescents, are associated with adolescents’ attitudes to some aspects of family life. The study was conducted on 862 students of the final year of high school, of whom 385 were male and 477 female. The results showed a statistically significant correlation between the assessed family interaction dimensions and adolescents’ attitudes to family life, with the exception of the attitude to work. The results obtained can be used in organizing programs focusing on preparation of young people for parental and marital roles and strengthening the skills required later in their family lives for constructive solving of the problems they will encounter.

  18. Marginal elasticity of periodic triangulated origami (United States)

    Chen, Bryan; Sussman, Dan; Lubensky, Tom; Santangelo, Chris

    Origami, the classical art of folding paper, has inspired much recent work on assembling complex 3D structures from planar sheets. Origami, and more generally hinged structures with rigid panels, where all faces are triangles have special properties due to having a bulk balance of mechanical degrees of freedom and constraints. We study two families of periodic triangulated origami structures, one based on the Miura ori and one based on a kagome-like pattern due to Ron Resch. We point out the consequences of the balance of degrees of freedom and constraints for these ''metamaterial plates'' and show how the elasticity can be tuned by changing the unit cell geometry.

  19. Family perspectives about Down syndrome. (United States)

    Skotko, Brian G; Levine, Susan P; Macklin, Eric A; Goldstein, Richard D


    National medical organizations recommend that during prenatal counseling sessions, healthcare providers discuss how having a child with Down syndrome (DS) might impact the family unit. Few studies, to date, have surveyed families about their life experiences. For this investigation, we examined 41 family attitudes, which were obtained from mailed questionnaires completed by 1,961 parents/guardians, 761 brothers/sisters, and 283 people with DS who were members of six DS non-profit organizations, chosen for their size, ethnic/racial diversities, and geographic distribution throughout the United States. About 83% of families reported to all being proud of the family member with DS, and 87% reported to all feeling love for the member with DS. Younger siblings (ages 9-11) were more likely to feel embarrassed by their sibling with DS if their parents/guardians also did. If one or more parents/guardians felt that their children without DS did have a good relationship with their child with DS, siblings were more likely to report that they loved and liked their brother/sister with DS. Overall, our data demonstrate that positive themes tend to dominate within modern-day families who have members with DS, although challenges were not insignificant for some. © 2015 Wiley Periodicals, Inc.

  2. Quasiaxially symmetric stellarators with three field periods

    International Nuclear Information System (INIS)

    Garabedian, P.; Ku, L.


    Compact hybrid configurations with two field periods have been studied recently as candidates for a proof of principle experiment at the Princeton Plasma Physics Laboratory. This project has led us to the discovery of a family of quasiaxially symmetric stellarators with three field periods that have significant advantages, although their aspect ratios are a little larger. They have reversed shear and perform better in a local analysis of ballooning modes. Nonlinear equilibrium and stability calculations predict that the average beta limit will be at least as high as 4% if the bootstrap current turns out to be as big as that expected in comparable tokamaks. The concept relies on a combination of helical fields and bootstrap current to achieve adequate rotational transform at low aspect ratio. copyright 1999 American Institute of Physics

  3. Episodic spontaneous hypothermia: a periodic childhood syndrome. (United States)

    Ruiz, Cynthia; Gener, Blanca; Garaizar, Carmen; Prats, José M


    Episodic spontaneous hypothermia is an infrequent disorder, with unknown pathogenic mechanisms. A systemic cause or underlying brain lesion has not been found for the disease. We report four new patients, 3-9 years old, with episodic hypothermia lower than 35 degrees C, marked facial pallor, and absent shivering. The episodes could last a few hours or four days, and recurred once a week or every 2-3 months. Two patients also demonstrated bradycardia, mild hypertension, and somnolence during the events; in one of them, profuse sweating was also a feature, and all four presented with either headache, a periodic childhood syndrome, or both (recurrent abdominal pain, cyclic vomiting, or vertigo). Three patients reported a family history of migraine. Neurologic examination, endocrine function, and imaging studies were normal. Migraine prophylactic therapy was of moderate efficacy. Spontaneous resolution was observed in one patient. The clinical characteristics of the syndrome allow for its inclusion as a childhood periodic syndrome related to migraine.

  12. Families and family therapy in Hong Kong. (United States)

    Tse, Samson; Ng, Roger M K; Tonsing, Kareen N; Ran, Maosheng


    Family therapy views humans not as separate entities, but as embedded in a network of relationships, highlighting the reciprocal influences of one's behaviours on one another. This article gives an overview of family demographics and the implementation of family therapy in Hong Kong. We start with a review of the family demographics in Hong Kong and brief notes on families in mainland China. Demographics show that the landscape has changed markedly in the past decade, with more cross-border marriages, an increased divorce rate, and an ageing overall population - all of which could mean that there is increasing demand for professional family therapy interventions. However, only a limited number of professionals are practising the systems-based approach in Hong Kong. Some possible reasons as to why family therapy is not well disseminated and practised are discussed. These reasons include a lack of mental health policy to support family therapy, a lack of systematic family therapy training, and a shortage of skilled professionals. Furthermore, challenges in applying the western model in Chinese culture are also outlined. We conclude that more future research is warranted to investigate how family therapy can be adapted for Chinese families.

  13. The period function of the generalized Lotka-Volterra centers (United States)

    Villadelprat, J.


    The present paper deals with the period function of the quadratic centers. In the literature different terminologies are used to classify these centers, but essentially there are four families: Hamiltonian, reversible , codimension four Q4 and generalized Lotka-Volterra systems . Chicone [C. Chicone, Review in MathSciNet, Ref. 94h:58072] conjectured that the reversible centers have at most two critical periods, and that the centers of the three other families have a monotonic period function. With regard to the second part of this conjecture, only the monotonicity of the Hamiltonian and Q4 families [W.A. Coppel, L. Gavrilov, The period function of a Hamiltonian quadratic system, Differential Integral Equations 6 (1993) 1357-1365; Y. Zhao, The monotonicity of period function for codimension four quadratic system Q4, J. Differential Equations 185 (2002) 370-387] has been proved. Concerning the family, no substantial progress has been made since the middle 80s, when several authors showed independently the monotonicity of the classical Lotka-Volterra centers [F. Rothe, The periods of the Volterra-Lokta system, J. Reine Angew. Math. 355 (1985) 129-138; R. Schaaf, Global behaviour of solution branches for some Neumann problems depending on one or several parameters, J. Reine Angew. Math. 346 (1984) 1-31; J. Waldvogel, The period in the Lotka-Volterra system is monotonic, J. Math. Anal. Appl. 114 (1986) 178-184]. By means of the first period constant one can easily conclude that the period function of the centers in the family is monotone increasing near the inner boundary of its period annulus (i.e., the center itself). Thus, according to Chicone's conjecture, it should be also monotone increasing near the outer boundary, which in the Poincaré disc is a polycycle. In this paper we show that this is true. In addition we prove that, except for a zero measure subset of the parameter plane, there is no bifurcation of critical periods from the outer boundary. Finally we

  14. Planetary perturbations and the origins of short-period comets

    International Nuclear Information System (INIS)

    Quinn, T.; Tremaine, S.; Duncan, M.


    To investigate the dynamical plausibility of possible sources for the short-period comets, a representative sample of comet orbits in the field of the sun and the giant planets was integrated, with the aim to determine whether the distribution of orbits from a proposed source that reach observable perihelia (q less than 2.5 AU) matches the observed distribution of short-period orbits. It is found that the majority of the short-period comets, those with orbital period P less than 20 yr (the Jupiter family), cannot arise from isotropic orbits with perihelia near Jupiter's orbit, because the resulting observable comet orbits have the wrong distribution in period, inclination, and argument of perihelion. The simulations also show that Jupiter-family comets cannot arise from isotropic orbits with perihelia in the Uranus-Neptune region. On the other hand, a source of low-inclination Neptune-crossing orbits yields a distribution of observable Jupiter-family comets that is consistent with the data in all respects. These results imply that the Jupiter-family comets arise from a disk source in the outer solar system rather than from the Oort comet cloud. 30 refs

  15. Family doctors' involvement with families in Estonia

    Directory of Open Access Journals (Sweden)

    Lember Margus


    Full Text Available Abstract Background Family doctors should care for individuals in the context of their family. Family has a powerful influence on health and illness and family interventions have been shown to improve health outcomes for a variety of health problems. The aim of the study was to investigate the Estonian family doctors' (FD attitudes to the patients' family-related issues in their work: to explore the degree of FDs involvement in family matters, their preparedness for management of family-related issues and their self-assessment of the ability to manage different family-related problems. Methods A random sample (n = 236 of all FDs in Estonia was investigated using a postal questionnaire. Altogether 151 FDs responded to the questionnaire (response rate 64%, while five of them were excluded as they did not actually work as FDs. Results Of the respondents, 90% thought that in managing the health problems of patients FDs should communicate and cooperate with family members. Although most of the family doctors agreed that modifying of the health damaging risk factors (smoking, alcohol and drug abuse of their patients and families is their task, one third of them felt that dealing with these problems is ineffective, or perceived themselves as poorly prepared or having too little time for such activities. Of the respondents, 58% (n = 83 were of the opinion that they could modify also relationship problems. Conclusions Estonian family doctors are favourably disposed to involvement in family-related problems, however, they need some additional training, especially in the field of relationship management.

  16. Impact of the infectious period on epidemics (United States)

    Wilkinson, Robert R.; Sharkey, Kieran J.


    The duration of the infectious period is a crucial determinant of the ability of an infectious disease to spread. We consider an epidemic model that is network based and non-Markovian, containing classic Kermack-McKendrick, pairwise, message passing, and spatial models as special cases. For this model, we prove a monotonic relationship between the variability of the infectious period (with fixed mean) and the probability that the infection will reach any given subset of the population by any given time. For certain families of distributions, this result implies that epidemic severity is decreasing with respect to the variance of the infectious period. The striking importance of this relationship is demonstrated numerically. We then prove, with a fixed basic reproductive ratio (R0), a monotonic relationship between the variability of the posterior transmission probability (which is a function of the infectious period) and the probability that the infection will reach any given subset of the population by any given time. Thus again, even when R0 is fixed, variability of the infectious period tends to dampen the epidemic. Numerical results illustrate this but indicate the relationship is weaker. We then show how our results apply to message passing, pairwise, and Kermack-McKendrick epidemic models, even when they are not exactly consistent with the stochastic dynamics. For Poissonian contact processes, and arbitrarily distributed infectious periods, we demonstrate how systems of delay differential equations and ordinary differential equations can provide upper and lower bounds, respectively, for the probability that any given individual has been infected by any given time.

  17. Rogue periodic waves of the modified KdV equation (United States)

    Chen, Jinbing; Pelinovsky, Dmitry E.


    Rogue periodic waves stand for rogue waves on a periodic background. Two families of travelling periodic waves of the modified Korteweg–de Vries (mKdV) equation in the focusing case are expressed by the Jacobian elliptic functions dn and cn. By using one-fold and two-fold Darboux transformations of the travelling periodic waves, we construct new explicit solutions for the mKdV equation. Since the dn-periodic wave is modulationally stable with respect to long-wave perturbations, the new solution constructed from the dn-periodic wave is a nonlinear superposition of an algebraically decaying soliton and the dn-periodic wave. On the other hand, since the cn-periodic wave is modulationally unstable with respect to long-wave perturbations, the new solution constructed from the cn-periodic wave is a rogue wave on the cn-periodic background, which generalizes the classical rogue wave (the so-called Peregrine’s breather) of the nonlinear Schrödinger equation. We compute the magnification factor for the rogue cn-periodic wave of the mKdV equation and show that it remains constant for all amplitudes. As a by-product of our work, we find explicit expressions for the periodic eigenfunctions of the spectral problem associated with the dn and cn periodic waves of the mKdV equation.

  19. Nonparametric Inference for Periodic Sequences

    KAUST Repository

    Sun, Ying


    This article proposes a nonparametric method for estimating the period and values of a periodic sequence when the data are evenly spaced in time. The period is estimated by a "leave-out-one-cycle" version of cross-validation (CV) and complements the periodogram, a widely used tool for period estimation. The CV method is computationally simple and implicitly penalizes multiples of the smallest period, leading to a "virtually" consistent estimator of integer periods. This estimator is investigated both theoretically and by simulation.We also propose a nonparametric test of the null hypothesis that the data have constantmean against the alternative that the sequence of means is periodic. Finally, our methodology is demonstrated on three well-known time series: the sunspots and lynx trapping data, and the El Niño series of sea surface temperatures. © 2012 American Statistical Association and the American Society for Quality.

  11. Periodic instantons and scattering amplitudes

    International Nuclear Information System (INIS)

    Khlebnikov, S.Yu.; Rubakov, V.A.; Tinyakov, P.G.


    We discuss the role of periodic euclidean solutions with two turning points and zero winding number (periodic instantons) in instanton induced processes below the sphaleron energy E sph . We find that the periodic instantons describe certain multiparticle scattering events leading to the transitions between topologically distinct vacua. Both the semiclassical amplitudes and inital and final states of these transitions are determined by the periodic instantons. Furthermore, the corresponding probabilities are maximal among all states of given energy. We show that at E ≤ E sph , the periodic instantons can be approximated by infinite chains of ordinary instantons and anti-instantons, and they naturally emerge as deformations of the zero energy instanton. In the framework of 2d abelian Higgs model and 4d electroweak theory we show, however, that there is not obvious relation between periodic instantons and two-particle scattering amplitudes. (orig.)

  12. Family emotional expressiveness and family structure

    Directory of Open Access Journals (Sweden)

    Čotar-Konrad Sonja


    Full Text Available The present paper scrutinizes the relationship between family emotional expressiveness (i.e., the tendency to express dominant and/or submissive positive and negative emotions and components of family structure as proposed in Olson’s Circumplex model (i.e., cohesion and flexibility, family communication, and satisfaction in families with adolescents. The study was conducted on a sample of 514 Slovenian adolescents, who filled out two questionnaires: the Slovenian version of Family Emotional Expressiveness - FEQ and FACES IV. The results revealed that all four basic dimensions of family functioning were significantly associated with higher/more frequent expressions of positive submissive emotions, as well as with lower/less frequent expressions of negative dominant emotions. Moreover, expressions of negative submissive emotions explained a small, but significant amount of variance in three out of four family functioning variables (satisfaction, flexibility, and communication. The importance of particular aspects of emotional expressiveness for family cohesion, flexibility, communication, and satisfaction is discussed, and the relevance of present findings for family counselling is outlined.

  17. Nontraditional family romance. (United States)

    Corbett, K


    Family stories lie at the heart of psychoanalytic developmental theory and psychoanalytic clinical technique, but whose family? Increasingly, lesbian and gay families, multiparent families, and single-parent families are relying on modern reproductive technologies to form families. The contemplation of these nontraditional families and the vicissitudes of contemporary reproduction lead to an unknowing of what families are, including the ways in which psychoanalysts configure the family within developmental theory. This article focuses on the stories that families tell in order to account for their formation--stories that include narratives about parental union, parental sexuality, and conception. The author addresses three constructs that inform family stories and that require rethinking in light of the category crises posed by and for the nontraditional family: (1) normative logic, (2) family reverie and the construction of a family romance, and (3) the primal scene. These constructs are examined in tandem with detailed clinical material taken from the psychotherapy of a seven-year-old boy and his two mothers.

  19. Forward Period Analysis Method of the Periodic Hamiltonian System.

    Directory of Open Access Journals (Sweden)

    Pengfei Wang

    Full Text Available Using the forward period analysis (FPA, we obtain the period of a Morse oscillator and mathematical pendulum system, with the accuracy of 100 significant digits. From these results, the long-term [0, 1060] (time unit solutions, ranging from the Planck time to the age of the universe, are computed reliably and quickly with a parallel multiple-precision Taylor series (PMT scheme. The application of FPA to periodic systems can greatly reduce the computation time of long-term reliable simulations. This scheme provides an efficient way to generate reference solutions, against which long-term simulations using other schemes can be tested.

  4. Rationalization of Comet Halley's periods (United States)

    Belton, Michael J. S.


    The sense of long axis orientation of Comet Halley during the Vega 1 encounter must be reversed from that deduced by Sagdeev et al. (1986) in order to harmonize the comet nucleus' Vega/Giotto-observed orientations with periodicities extracted from time-series brightness data. It is also demonstrated that Vega/Giotto observations can be satisfied by either a 2.2- or 3.7-day long-axis free precession period. A novel Fourier algorithm is used to reanalyze five independent data sets; strong evidence is adduced for periods harmonically related to a 7.4-day period. The preferred candidate models for Halley's nuclear rotation are characterized by a long-axis precession period of 3.7 days.

  5. Orbital periods of recurrent novae

    International Nuclear Information System (INIS)

    Schaefer, B.E.


    The class of recurrent novae (RN) with thermonuclear runaways contains only three systems (T Pyx, U Sco, and V394 CrA), for which no orbital periods are known. This paper presents a series of photometric observations where the orbital periods for all three systems are discovered. T Pyx is found to have sinusoidal modulation with an amplitude of 0.08 mag and a period of 2.3783 h (with a possible alias of 2.6403 h). U Sco is found to be an eclipsing system with an eclipse amplitude of roughly 1.5 mag and an orbital period of 1.2344 days. V394 CrA is found to have sinusoidal modulation with an amplitude of 0.5 mag and a period of 0.7577 days. Thus two out of three RN with thermonuclear runaways (or five out of six for all RN) have evolved companions. 16 refs

    A three-variable model of the Belousov-Zhabotinsky reaction system subject to external sinusoidal perturbations is investigated by means of frequency spectrum analysis. In the period-1 window of the model, the transitions from periodicity to chaos are observed; in the chaotic window, the transitions from chaos to periodicity are found. The former might be understood by the circle map of two coupled oscillators, and the latter is partly explained by the resonance between the main frequency of the chaos and the frequency of the external periodic perturbations

  10. Earnings Management and CSR Disclosure. Family vs. Non-Family Firms

    Directory of Open Access Journals (Sweden)

    Giovanna Gavana


    Full Text Available Building on Institutional theory and Signaling theory, integrated with the socioemotional wealth (SEW approach, we studied the effect of earnings management (EM practices on a firm’s Corporate Social Responsibility (CSR disclosure behavior. In so doing, we analyzed a sample of 226 non-financial, family and non-family listed firms for the period, 2006–2015. Our results suggest that family firms, in instances of downward earnings management, are more prone to diverting attention from these practices by means of CSR disclosure, compared to non-family firms, although the level of family ownership exerts a moderating effect. Moreover, we found that a firm’s visibility, in terms of size, significantly enhances this behavior and that the effect is higher for family firms.

  11. The Periodic Table in Croatia

    Directory of Open Access Journals (Sweden)

    Raos, N.


    Full Text Available The Croatian (Yugoslav Academy of Sciences and Arts was the first academy to elect D. I. Mendeleev as its honorary member (1882, whereas the periodic table of the elements has been taught regularly at the Zagreb University since 1888. The early interest of Croatian chemists in the periodic table should be attributed primarily to their pan-Slavic attitude, particularly as proof that Slavic people were able to produce "their own Newtons" (M. V. Lomonosov and D. I. Mendeleev. Such enthusiastic views, however, did not help in analyzing the contribution of Mendeleev and other scientists to the discovery and development of the periodic table of the elements.

  16. Resilience of refugee families

    Directory of Open Access Journals (Sweden)

    Batić Dragana


    Full Text Available This study attempted to find a correlation between the trauma of family members of war and exile, and the characteristics of family functioning and lasted from 1992-1995. The term “family resilience” refers to the processes of adaptation and coping in the family as a functional unit. This paper presents a study of refugee families from Bosnia, who lived in refugee camps in Macedonia during the war of 1992- 1995. Data were obtained by interviews, observations, and a number of psychological instruments especially for children and parents, which measured the effects of psychological stress and family relationships. Based on the results obtained by quantitative and qualitative analysis, and application of theoretical models of systemic theory and family therapy, existence for four types of refugee families has been found and described, depending on the structure and the level of functionality.

  1. Periodic orbits of the hydrogen molecular ion and their quantization

    International Nuclear Information System (INIS)

    Duan, Y.; Yuan, J.; Bao, C.


    In a classical study of the hydrogen molecular ion beyond the Born-Oppenheimer approximation (BOA), we have found that segments of trajectories resemble that of the Born-Oppenheimer approximation periodic orbits. The importance of this fact to the classical understanding of chemical bonding leads us to a systematic study of the periodic orbits of the planar hydrogen molecular ion within the BOA. Besides introducing a classification scheme for periodic orbits, we discuss the convergence properties of families of periodic orbits and their bifurcation patterns according to their types. Semiclassical calculations of the density of states based on these periodic orbits yield results in agreement with the exact quantum eigenvalues of the hydrogen molecular ion system

  2. Topological imprint for periodic orbits

    International Nuclear Information System (INIS)

    Martín, Jesús San; Moscoso, Ma José; Gómez, A González


    The more self-crossing points an orbit has the more complex it is. We introduce the topological imprint to characterize crossing points and focus on the period-doubling cascade. The period-doubling cascade topological imprint determines the topological imprint for orbits in chaotic bands. In addition, there is a closer link between this concept and the braids studied by Lettelier et al (2000 J. Phys. A: Math. Gen. 33 1809–25). (paper)

  3. Minimum period and the gap in periods of Cataclysmic binaries

    International Nuclear Information System (INIS)

    Paczynski, B.; Sienkiewicz, R.


    The 81 minute cutoff to the orbital periods of hydrogen-rich cataclysmic binaries is consistent with evolution of those systems being dominated by angular momentum losses due to gravitational radiation. Unfortunately, many uncertainties, mainly poorly known atmospheric opacities below 2000 K, make is physically impossible to verify the quadrupole formula for gravitational radiation by using the observed cutoff at 81 minutes. The upper boundary of the gap in orbital periods observed at about 3 hours is almost certainly due to enhanced angular momentum losses from cataclysmic binaries which have longer periods. The physical mechanism of those losses is not identified, but a possible importance of stellar winds is pointed out. The lower boundary of the gap may be explained with the oldest cataclysmic binaries, whose periods evolved past the minimum at 81 minutes and reached the value of 2 hours within about 12 x 10 9 years after the binary had formed. Those binaries should have secondary components of only 0.02 solar masses, and their periods could be used to estimate ages of the oldest cataclysmic stars, and presumably the age of Galaxy. An alternative explanation for the gap requires that binaries should be detached while crossing the gap. A possible mechanism for this phenomenon is discussed. It requires the secondary components to be about 0.2 solar masses in the binaries just below the gap

  8. Natural family planning. (United States)

    Brown, J B; Blackwell, L F; Billings, J J; Conway, B; Cox, R I; Garrett, G; Holmes, J; Smith, M A


    It is now well accepted that a woman can conceive from an act of intercourse for a maximum of only about 7 days of her menstrual cycle. The reliability of natural family planning depends on identifying this window of fertility without ambiguity. Several symptomatic markers, cervical mucus and basal body temperature, have been used extensively and with considerable success in most women but failures occur. Ovarian and pituitary hormone production show characteristic patterns during the cycle. Urinary estrogen and pregnanediol measurements yield reliable information concerning the beginning, peak, and end of the fertile period, provided that the assays are accurate and performed on timed specimens of urine. We have developed such enzyme immunoassays for urinary estrogen and pregnanediol glucuronides that can be performed at home. In the early versions of the assays, enzyme reaction rates were measured by eye, but more recently, a simple photoelectronic rate meter has been used. The final problem to be solved is not technologic but whether women are sufficiently motivated to expend the same time and effort each day for 10 days a month, with less cost, on fertility awareness as they spend on making a cup of tea.

  9. Commuting periodic operators and the periodic Wigner function

    International Nuclear Information System (INIS)

    Zak, J


    Commuting periodic operators (CPO) depending on the coordinate x-hat and the momentum p-hat operators are defined. The CPO are functions of the two basic commuting operators exp(i x-hat 2π/a) and exp(i/h p-hat a), with a being an arbitrary constant. A periodic Wigner function (PWF) w(x, p) is defined and it is shown that it is applicable in a normal expectation value calculation to the CPO, as done in the original Wigner paper. Moreover, this PWF is non-negative everywhere, and it can therefore be interpreted as an actual probability distribution. The PWF w(x, p) is shown to be given as an expectation value of the periodic Dirac delta function in the phase plane. (letter to the editor)

  10. Nanopublication beyond the sciences: the PeriodO period gazetteer

    Directory of Open Access Journals (Sweden)

    Patrick Golden


    Full Text Available The information expressed in humanities datasets is inextricably tied to a wider discursive environment that is irreducible to complete formal representation. Humanities scholars must wrestle with this fact when they attempt to publish or consume structured data. The practice of “nanopublication,” which originated in the e-science domain, offers a way to maintain the connection between formal representations of humanities data and its discursive basis. In this paper we describe nanopublication, its potential applicability to the humanities, and our experience curating humanities nanopublications in the PeriodO period gazetteer.

  11. Periodic testing in operative action

    International Nuclear Information System (INIS)

    Larm, T.


    Periodic testing forms a remarkable part of the regular work tasks of the shift crew. Testing is generally carried out beside the daily monitoring and control work. Even remarkable plant related differences may occur in the procedures and routines used in periodic testing. The goal is still always the same, to regularly ensure that the systems and equipment are in working order according to their design. This presentation studies with examples the execution and scope of periodic testing as well as the routines and procedures used in the testing in Loviisa power plant. The presentation is based on the testing procedures of Loviisa power plant and the aim is not to compare them to the procedures of other plants. The scope of periodic testing has increased and the routines and procedures have been developed as the operation experience has increased. The assessment of the need of periodic testing and the consideration of the practical execution possibilities should be a part of the plant's planning phase as a part of the planning process.

    Fleeing civil war involves managing life threatening events and multiple disruptions of everyday life. The theoretical potentials of analysing the recreation of everyday family life among Syrian refugees in Denmark is explored based on conceptualizations that emphasize the collective agency...... of family members in social historical contexts. Studying the multiple perspectives of family members shows how social support conceptualized as care practises is conflictual in the changing everyday family practices that are transformed by policy. The purpose of studying how families manage to flee civil...... war and struggle to recreate an everyday life in exile is to contribute with contextualization and expansion of mainstream understandings of family life, suffering, and resilience in refugee family trajectories in multiple contexts....

  15. Inflation from periodic extra dimensions

    Energy Technology Data Exchange (ETDEWEB)

    Higaki, Tetsutaro [Department of Physics, Keio University, Kanagawa 223-8522 (Japan); Tatsuta, Yoshiyuki, E-mail:, E-mail: [Department of Physics, Waseda University, Tokyo 169-8555 (Japan)


    We discuss a realization of a small field inflation based on string inspired supergravities. In theories accompanying extra dimensions, compactification of them with small radii is required for realistic situations. Since the extra dimension can have a periodicity, there will appear (quasi-)periodic functions under transformations of moduli of the extra dimensions in low energy scales. Such a periodic property can lead to a UV completion of so-called multi-natural inflation model where inflaton potential consists of a sum of multiple sinusoidal functions with a decay constant smaller than the Planck scale. As an illustration, we construct a SUSY breaking model, and then show that such an inflaton potential can be generated by a sum of world sheet instantons in intersecting brane models on extra dimensions containing orbifold. We show also predictions of cosmic observables by numerical analyzes.

  16. Periodicity, the Canon and Sport

    Directory of Open Access Journals (Sweden)

    Thomas F. Scanlon


    Full Text Available The topic according to this title is admittedly a broad one, embracing two very general concepts of time and of the cultural valuation of artistic products. Both phenomena are, in the present view, largely constructed by their contemporary cultures, and given authority to a great extent from the prestige of the past. The antiquity of tradition brings with it a certain cachet. Even though there may be peripheral debates in any given society which question the specifics of periodization or canonicity, individuals generally accept the consensus designation of a sequence of historical periods and they accept a list of highly valued artistic works as canonical or authoritative. We will first examine some of the processes of periodization and of canon-formation, after which we will discuss some specific examples of how these processes have worked in the sport of two ancient cultures, namely Greece and Mesoamerica.

  17. Periodicity and repeatability in data (United States)

    Southwood, D.

    Using magnetic data from the first two years in Saturn orbit, the basic periodicity of apparent is examined with the aim of elucidating the `cam' shaft model of Espinosa et al. (2003) identifying the nature of the `cam' and giving a definitive period for its rotation. An initial hypothesis, supported by the spectral analysis of analysis of the first 8 months in orbit Gianpieri et al. (2006), is made that the source of the period is linked to something inside the planet and therefore that the source inertia means that the period effectively does not change over the 2 years. Moreover one expects that the source phase is fixed. Using this approach, not only can the period identified by spectral analysis (647.1 + 0.6 min.) be verified but also by phase analysis between successive passes over the 2 years the period can be refined to 647.6 + 0.1 min. The signal itself is remarkably reproducible from pass to pass. It appears in all three components of the field and its polarisation is unambiguously not attributable to direct detection of an internal field. Not only does the signal not decay rapidly with distance from the planet, but although it has the m=1 symmetry of a tilted dipole, the field lines diverge from the planet indicating an exterior source. This feature led to the `cam' model. The polarisation and comparisons of passes with different latitude profiles show a surprising north-south symmetry in the azimuthal field. The absence of asymmetry with respect to the magnetic equator rules out a direct magnetospheric-ionospheric interaction source. Accordingly, it is proposed that the basic `cam' effect is generated by a single hemisphere anomaly which creates hemisphere to hemisphere field aligned currents. The existence of Saturn phase related anomaly appears to produce a basic asymmetry in the inner magnetosphere that sets the phase of both an inflowing and outflowing sector in a rotating circulation system.

  18. An improved test for periodicity

    International Nuclear Information System (INIS)

    Davies, S.R.


    I discuss two widely used methods of testing for periodicity, phase dispersion minimization and epoch-folding. Using an analysis of variance approach, I demonstrate the close relationship between these two methods. I also show that the significance test sometimes used in phase dispersion minimization is statistically inaccurate, and that the test used in epoch-folding is an approximation valid only for large sample sizes. I propose a new test statistic, applicable to either epoch-folding or PDM, which is statistically sound for all sample sizes, and which is also more sensitive to periodicity than the test statistics previously used with these two methods.

    Barg, Christian; Secchi, Argimiro R.; Trierweiler, Jorge O. [Rio Grande do Sul Univ., Porto Alegre, RS (Brazil). Dept. de Engenharia Quimica]. E-mail:;;


    The periodic adsorption processes have been widely used for industrial applications, mainly because it spends less energy than the usual gas separation processes, like the cryogenic distillation. The largest commercial application of periodic adsorption processes is the pressure swing adsorption (PSA) applied to hydrogen purification. Although its wide use in the chemical and petrochemical industry, there are no reports in the open literature about complete modeling studies of a complex commercial unit, with multiple adsorbents and multiple beds and several feed components. This study has as objective the modeling, optimization and dynamical analysis of an industrial PSA unit for hydrogen purification. (author)

    Signoret, J.P.


    There is at the present time a need in accurate models to asess the availability of periodically tested stand-by systems. This paper shows how to improve the well known 'saw-tooth curve' model in order to take into account various reliability parameters. A model is developed to assess the pointwise and the mean availabilities of periodically tested stand-by systems. Exact and approxination formulae are given. In addition, the model developed herein leads to optimize the test interval in order to minimize the mean unavailability. A safety diesel in a nuclear power plant is given as an example

  4. [Family therapy of encopresis]. (United States)

    Spitczok von Brisinski, Ingo; Lüttger, Fred


    Encopresis is a taboo symptom, which is connected with great suffering from mental pressure not only for the children concerned, but also their relatives. Family related approaches are indispensable to understand encopresis, because as a result of high symptom persistence and psychological comorbidity in many cases a purely behavior-therapeutic, symptom focused approach is not sufficient, and further psychotherapeutic interventions are necessary. There is a strong temporal correlation between family interaction and frequency of soiling and changes of interaction influence changes in soiling more than the other way round. In a literature review different family relationship patterns and approaches of family therapy are represented regarding encopresis. Meaningful differences for family therapy are represented regarding primary/secondary encopresis, encopresis with/without comorbid psychiatric disorder as well as encopresis with/without dysfunctional family interaction. Distinctions are made between symptom focused, not-symptom focused and combined family therapeutic approaches, which are illustrated with case examples of outpatient and inpatient treatment. Symptom focused family therapy like e.g. externalizing of the soiling is helpful also if no dysfunctional family interaction patterns are present, because all family members can contribute to treatment success according to their own resources.

  13. Familial testicular cancer and developmental anomalies

    International Nuclear Information System (INIS)

    Ondrus, D.; Kuba, D.; Chrenova, S.; Matoska, J.


    Familial occurrence belongs to factors followed in etiology and pathogenesis of testicular germ-cell tumors. Association with abnormal testicular development, or with other risk factors is relatively frequent. In our material 650 patients had been treated for testicular cancer in the period of 1981-1995. Familial occurrence was observed 7-times (1.08), most frequently in combination with cryptorchidism. Individual families were analyzed in details, including HLA typing. On basis of the observations the supplementation of initial examination of each patient with suspicious testicular cancer with detailed familiar history aimed also at the occurrence of urogenital developmental anomalies and tumors has been recommended. The knowledge about familial tumor occurrence in the first-degree relatives in combination with thorough testicular self-examination is being considered of great importance in the secondary prevention.

  14. Family psychology: Past and future reflections on the field. (United States)

    Parke, Ross D


    Prominent issues in the field of family psychology during my term as editor (1998-2003) of this journal were briefly noted, including a focus on marital issues, divorce, remarriage and family conflict. Parenting, attachment and parent-child relationships were also significant topics in this period. Special sections of the journal focused on cultural variations, families and the law, families and religion, and family routines and rituals. Several neglected issues that need more attention in the future were noted. These include the need to recognize the embeddedness of families in socioecological contexts, the importance of monitoring the impact of secular changes on families, and the value and limitations of viewing family psychology as a separate field. Other topics for a future agenda include the challenge of defining "family" in the midst of changing family forms, the effects of technological change on families, and the challenges of integrating biological research into the family psychology agenda. A multilevel bio-social approach to family research was recommended. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  15. Pseudo-periodic maps and degeneration of Riemann surfaces

    CERN Document Server

    Matsumoto, Yukio


    The first part of the book studies pseudo-periodic maps of a closed surface of genus greater than or equal to two. This class of homeomorphisms was originally introduced by J. Nielsen in 1944 as an extension of periodic maps. In this book, the conjugacy classes of the (chiral) pseudo-periodic mapping classes are completely classified, and Nielsen’s incomplete classification is corrected. The second part applies the results of the first part to the topology of degeneration of Riemann surfaces. It is shown that the set of topological types of all the singular fibers appearing in one-parameter holomorphic families of Riemann surfaces is in a bijective correspondence with the set of conjugacy classes of the pseudo-periodic maps of negative twists. The correspondence is given by the topological monodromy.

  17. Advancing family psychology. (United States)

    Fiese, Barbara H


    To realize the broad and complex nature of the field of family psychology, I have slightly revised the mission statement of the Journal of Family Psychology (JFP) to capture contemporary scholarship in family psychology and to advance systems perspectives in this top-tier scientific journal. Over the next 6 years, I hope that authors will consider JFP as an outlet for their best work in the following areas: (1) JFP addresses societal challenges faced by families today; (2) JFP publishes important studies on what makes couple and family relationships work; (3) JFP is a leader in publishing reports that use cutting-edge sophisticated approaches to research design and data analysis; and (4) JFP imparts knowledge about effective therapy and prevention programs relevant to couples and families. The journal is also expanding its publication rate to eight issues per year. (c) 2016 APA, all rights reserved).

  18. Sharing family and household:

    DEFF Research Database (Denmark)

    Winther, Ida Wentzel

    Keynote: Family relationships are normatively assumed to be characterized by ‘sharing’, such as living together in the same home, occupying the same place, sharing stuff, blood and biology, spending special and ordinary time together, and consequently creating shared biographical experiences....... In that way, families are thrown into togetherness. At the same time, we see families in varying forms where 'sharing' is lived and contested differently. In Denmark, many children live in nuclear families, and many live in different variations of more than one household. For those who share household...... and family, 'sharing' will be a basic condition. No matter what, they should share life circumstances, more stories, more places and spaces, more households families with both kin and non-kin. This keynote addresses the particular of children’s experiences of living apart and/or living together in sharing...

    lntergenerational transfers are extremely important in family businesses, because of the economic advantages of passing the business to the next generation as a 'going concern'. In order to pass the business as a 'going concern' it is necessary for the operators and the successors to work together for a specified period. This intergenerational cooperation allows the entrepreneurial family to utilize the benefits of within-family implicit old-age security arrangements. We suggest a method to...

  20. Familial Transient Global Amnesia

    Directory of Open Access Journals (Sweden)

    R.Rhys Davies


    Full Text Available Following an episode of typical transient global amnesia (TGA, a female patient reported similar clinical attacks in 2 maternal aunts. Prior reports of familial TGA are few, and no previous account of affected relatives more distant than siblings or parents was discovered in a literature survey. The aetiology of familial TGA is unknown. A pathophysiological mechanism akin to that in migraine attacks, comorbidity reported in a number of the examples of familial TGA, is one possibility. The study of familial TGA cases might facilitate the understanding of TGA aetiology.

  2. Balancing related methods for minimal realization of periodic systems


    Varga, A.


    We propose balancing related numerically reliable methods to compute minimal realizations of linear periodic systems with time-varying dimensions. The first method belongs to the family of square-root methods with guaranteed enhanced computational accuracy and can be used to compute balanced minimal order realizations. An alternative balancing-free square-root method has the advantage of a potentially better numerical accuracy in case of poorly scaled original systems. The key numerical co...

  3. Evolutionary dynamics of incubation periods. (United States)

    Ottino-Loffler, Bertrand; Scott, Jacob G; Strogatz, Steven H


    The incubation period for typhoid, polio, measles, leukemia and many other diseases follows a right-skewed, approximately lognormal distribution. Although this pattern was discovered more than sixty years ago, it remains an open question to explain its ubiquity. Here, we propose an explanation based on evolutionary dynamics on graphs. For simple models of a mutant or pathogen invading a network-structured population of healthy cells, we show that skewed distributions of incubation periods emerge for a wide range of assumptions about invader fitness, competition dynamics, and network structure. The skewness stems from stochastic mechanisms associated with two classic problems in probability theory: the coupon collector and the random walk. Unlike previous explanations that rely crucially on heterogeneity, our results hold even for homogeneous populations. Thus, we predict that two equally healthy individuals subjected to equal doses of equally pathogenic agents may, by chance alone, show remarkably different time courses of disease.

  4. Period of an Interrupted Pendulum (United States)

    Miller, Bradley E.


    While demonstrating a classic conservation-of-energy problem to my AP Physics students, I became curious about the periodic motion that ensued for certain initial conditions. The original problem consists of releasing a mass at the end of a string from an initial position horizontal to the plane of a table. The string comes in contact with a peg some distance below the point where the string is attached at the top. One is asked to find what minimum fraction of the string's length should the peg be placed to have the mass complete a circle about the peg. However, when the mass is released from much lower heights, the system undergoes periodic motion that can be thought of as an interrupted pendulum.

  5. Periodicity of the stable isotopes

    CERN Document Server

    Boeyens, J C A


    It is demonstrated that all stable (non-radioactive) isotopes are formally interrelated as the products of systematically adding alpha particles to four elementary units. The region of stability against radioactive decay is shown to obey a general trend based on number theory and contains the periodic law of the elements as a special case. This general law restricts the number of what may be considered as natural elements to 100 and is based on a proton:neutron ratio that matches the golden ratio, characteristic of biological and crystal growth structures. Different forms of the periodic table inferred at other proton:neutron ratios indicate that the electronic configuration of atoms is variable and may be a function of environmental pressure. Cosmic consequences of this postulate are examined. (author)

  14. A period-doubling cascade precedes chaos for planar maps. (United States)

    Sander, Evelyn; Yorke, James A


    A period-doubling cascade is often seen in numerical studies of those smooth (one-parameter families of) maps for which as the parameter is varied, the map transitions from one without chaos to one with chaos. Our emphasis in this paper is on establishing the existence of such a cascade for many maps with phase space dimension 2. We use continuation methods to show the following: under certain general assumptions, if at one parameter there are only finitely many periodic orbits, and at another parameter value there is chaos, then between those two parameter values there must be a cascade. We investigate only families that are generic in the sense that all periodic orbit bifurcations are generic. Our method of proof in showing there is one cascade is to show there must be infinitely many cascades. We discuss in detail two-dimensional families like those which arise as a time-2π maps for the Duffing equation and the forced damped pendulum equation.

  16. Multiphase patterns in periodically forced oscillatory systems

    International Nuclear Information System (INIS)

    Elphick, C.; Hagberg, A.; Meron, E.


    Periodic forcing of an oscillatory system produces frequency locking bands within which the system frequency is rationally related to the forcing frequency. We study extended oscillatory systems that respond to uniform periodic forcing at one quarter of the forcing frequency (the 4:1 resonance). These systems possess four coexisting stable states, corresponding to uniform oscillations with successive phase shifts of π/2. Using an amplitude equation approach near a Hopf bifurcation to uniform oscillations, we study front solutions connecting different phase states. These solutions divide into two groups: π fronts separating states with a phase shift of π and π/2 fronts separating states with a phase shift of π/2. We find a type of front instability where a stationary π front 'decomposes' into a pair of traveling π/2 fronts as the forcing strength is decreased. The instability is degenerate for an amplitude equation with cubic nonlinearities. At the instability point a continuous family of pair solutions exists, consisting of π/2 fronts separated by distances ranging from zero to infinity. Quintic nonlinearities lift the degeneracy at the instability point but do not change the basic nature of the instability. We conjecture the existence of similar instabilities in higher 2n:1 resonances (n=3,4,hor-ellipsis) where stationary π fronts decompose into n traveling π/n fronts. The instabilities designate transitions from stationary two-phase patterns to traveling 2n-phase patterns. As an example, we demonstrate with a numerical solution the collapse of a four-phase spiral wave into a stationary two-phase pattern as the forcing strength within the 4:1 resonance is increased. copyright 1999 The American Physical Society

  4. Family intervention for schizophrenia. (United States)

    Pharoah, F M; Mari, J J; Streiner, D


    It has been showed that people with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of their emotions. Psychosocial interventions designed to reduce these levels of expressed emotions within families now exist for mental health workers. These interventions are proposed as adjuncts rather than alternatives to drug treatments, and their main purpose is to decrease the stress within the family and also the rate of relapse. To estimate the effects of family psychosocial interventions in community settings for the care of those with schizophrenia or schizophrenia-like conditions compared to standard care. Electronic searches of the Cochrane Library (Issue 2, 1998), the Cochrane Schizophrenia Group's Register (June 1998), EMBASE (1981-1995) and MEDLINE (1966-1995) were undertaken and supplemented with reference searching of the identified literature. Randomised or quasi-randomised studies were selected if they focused on families of people with schizophrenia or schizoaffective disorder and compared community-orientated family-based psychosocial intervention of more than five sessions to standard care. Data were reliably extracted, and, where appropriate and possible, summated. Peto odds ratios (OR), their 95% confidence intervals (CI) and number needed to treat (NNT) were estimated. The reviewers assume that people who died or dropped out had no improvement and tested the sensitivity of the final results to this assumption. Family intervention may decrease the frequency of relapse (one year OR 0.57 CI 0.4-0.8, NNT 6.5 CI 4-14). The trend over time of this main finding is towards the null and some small but negative studies may not have been identified by the search. Family intervention may decrease hospitalisation and encourage compliance with medication but data are few and equivocal. Family intervention does not

    This presentation explores the question: What motivates the use of tracking technologies in families, and how does the use transform the relations between parent and child? The purpose is to investigate why tracking technologies are used in families and how these technologies potentially change...... the relation between parents and children. The use of tracking technologies in families implicate negotiations about the boundaries of trust and intimacy in parent-child relations which can lead to strategies of resistance or modification (Fotel and Thomsen, 2004; Rooney, 2010; Steeves and Jones, 2010......). In the presentation, we report from a qualitative study that focuses on intergenerational relations. The study draws on empirical data from workshops with Danish families as well as individual and group interviews. We aim to gain insights about the sharing habits and negotiations in intimate family relations...

  8. Comparative study of thyrotoxic periodic paralysis from idiopathic hypokalemic periodic paralysis: An experience from India

    Directory of Open Access Journals (Sweden)

    J Kalita


    Full Text Available Objective: There is paucity of reports on thyrotoxic periodic paralysis (TPP from India. We report the patients with TPP and compare them with idiopathic hypokalemic periodic paralysis (IHPP. Materials and Methods: Patients with hypokalemic periodic paralysis (HPP treated during the past 11 years were evaluated retrospectively. Their demographic parameters, family history, clinical features, precipitating factors, severity of weakness, laboratory parameters and rapidity of recovery were recorded. The demographic, clinical and laboratory parameters of TPP and IHPP were compared. Results: During the study period, we managed 52 patients with HPP; nine (17.3% of whom had TPP and 27 (52% had IHPP. The demographic, precipitating factors, number of attacks and severity of limb weakness were similar between the TPP and IHPP groups, except in the IHPP group, bulbar weakness was present in four and respiratory paralysis in six, needing artificial ventilation in two patients. Serum potassium was significantly lower in TPP (2.21 ± 0.49 compared with IHPP (2.67 ± 0.59, P = 0.04. Four patients with TPP had subclinical thyrotoxicosis and two had subclinical hyperthyroidism. Rebound hyperkalemia occurred in both TPP and IHPP (three versus eight patients. The recovery was faster in IHPP (26.7 ± 15.4 h compared with TPP (34.0 ± 14.0 h, but was statistically insignificant. Conclusion: TPP constitutes 17.3% of HPP, and absence of clinical features of thyrotoxicosis and subclinical hyperthyroidism in TPP is not uncommon. Clinical features, demographic profile and rebound hyperkalemia are similar in both TPP and IHPP. The serum potassium level is significantly low in the TPP compared with the IHPP group.

  9. Long-Period Solar Variability

    Energy Technology Data Exchange (ETDEWEB)



    Terrestrial climate records and historical observations of the Sun suggest that the Sun undergoes aperiodic oscillations in radiative output and size over time periods of centuries and millenia. Such behavior can be explained by the solar convective zone acting as a nonlinear oscillator, forced at the sunspot-cycle frequency by variations in heliomagnetic field strength. A forced variant of the Lorenz equations can generate a time series with the same characteristics as the solar and climate records. The timescales and magnitudes of oscillations that could be caused by this mechanism are consistent with what is known about the Sun and terrestrial climate.

  14. Periodic orbits around areostationary points in the Martian gravity field

    International Nuclear Information System (INIS)

    Liu Xiaodong; Baoyin Hexi; Ma Xingrui


    This study investigates the problem of areostationary orbits around Mars in three-dimensional space. Areostationary orbits are expected to be used to establish a future telecommunication network for the exploration of Mars. However, no artificial satellites have been placed in these orbits thus far. The characteristics of the Martian gravity field are presented, and areostationary points and their linear stability are calculated. By taking linearized solutions in the planar case as the initial guesses and utilizing the Levenberg-Marquardt method, families of periodic orbits around areostationary points are shown to exist. Short-period orbits and long-period orbits are found around linearly stable areostationary points, but only short-period orbits are found around unstable areostationary points. Vertical periodic orbits around both linearly stable and unstable areostationary points are also examined. Satellites in these periodic orbits could depart from areostationary points by a few degrees in longitude, which would facilitate observation of the Martian topography. Based on the eigenvalues of the monodromy matrix, the evolution of the stability index of periodic orbits is determined. Finally, heteroclinic orbits connecting the two unstable areostationary points are found, providing the possibility for orbital transfer with minimal energy consumption.

  15. Periodic trajectories for a two-dimensional nonintegrable Hamiltonian

    International Nuclear Information System (INIS)

    Baranger, M.; Davies, K.T.R.


    A numerical study is made of the classical periodic trajectories for the two-dimensional nonintegrable Hamiltonian H = 1/2(p 2 /sub x/+p 2 /sub y/)+(y-1/2x 2 ) 2 +0.05 x 2 . In addition to x--y pictures of the trajectories, E--tau (energy--period) plots of the periodic families are presented. Efforts have been ade to include all trajectories with short periods and all simple branchings of these trajectories. The monodromy matrix has been calculated in all cases, and from it the stability properties are derived. The topology of the E--tau plot has been explored, with the following results. One family may have several stable regions. The plot is not completely connected; there are islands. The plot is not a tree; there are cycles. There are isochronous branchings, period-doublings, and period-multiplyings of higher orders, and examples of each of these are presented. There is often more than one branch issuing from a branch point. Some general empirical rules are inferred. In particular, the existence of isochronous branching is seen to be a consequence of the symmetry of the Hamiltonian. All these results agree with the general classification of possible branchings derived in Ref. [10]. (M. A. M. de Aguiar, C. P. Malta, M. Baranger, and K. T. R. Davies, in preparation). Finally, some nonperiodic trajectories are calculated to illustrate the fact that stable periodic trajectories lie in ''regular'' regions of phase space, while unstable ones lie in ''chaotic'' regions

    Full Text Available The definition of giftedness is related to the existence of high abilities in several and different fields and involves the study of process as intelligence, motivation, creativity and leadership. Due to the lack of research in this area, the present study aimed to review researches about giftedness on Brazilian periodic publications, in two databases: Scielo and Pepsic. The results pointed to the existence of 19 theorical and empiric articles, published between 2002 and 2009, that approached distinct dimensions of giftedness: conceptual definitions, models and forms of identification, models of attendance, Brazilian laws to guide the performance, researches with teachers, family and school environment, studies of cognitive, social and emotional dimension, finally behaviors and emotional disorders related to the giftedness. The articles analysis allowed concluding the recent interest for the theme, it was observed divergences in the definition of the concept, the lack of specific tests, with validity and standards, beyond the recognition of the importance of the school environment and the psychologis

  19. Work-Family Conflict, Family-Supportive Supervisor Behaviors (FSSB), and Sleep Outcomes (United States)

    Crain, Tori L.; Hammer, Leslie B.; Bodner, Todd; Kossek, Ellen Ernst; Moen, Phyllis; Lilienthal, Richard; Buxton, Orfeu M.


    Although critical to health and well-being, relatively little research has been conducted in the organizational literature on linkages between the work-family interface and sleep. Drawing on Conservation of Resources theory, we use a sample of 623 information technology workers to examine the relationships between work-family conflict, family-supportive supervisor behaviors (FSSB), and sleep quality and quantity. Validated wrist actigraphy methods were used to collect objective sleep quality and quantity data over a one week period of time, and survey methods were used to collect information on self-reported work-family conflict, FSSB, and sleep quality and quantity. Results demonstrated that the combination of predictors (i.e., work-to-family conflict, family-to-work conflict, FSSB) was significantly related to both objective and self-report measures of sleep quantity and quality. Future research should further examine the work-family interface to sleep link and make use of interventions targeting the work-family interface as a means for improving sleep health. PMID:24730425

    Lapčević Mirjana


    Full Text Available The family, as the basic social unit, has a decisive role in the health and disease of its members. It is the primary unit where health needs are formed and solved. By its own resources the family independently resolves about 75% of the total health requirements. In the paper the authors study family characteristics which influence family health and diseases, indicators of family health and the scale of life values. Also, the study evaluates social factors, communication and the influence of the usage of psychoactive substances on family health and the quality of family life. To form the personality of a child three factors are most significant: love, the feeling of safety and the presence of harmonious relationship between the parents. Life harmony in a family also depends on the quality of structural components of the personality and the interaction of motivation of its members. Early childhood determines the future personality of the adult person. At that period, habits and partially attitudes are formed. In harmonious family relationships the parents are the role model to children. Verbal and non-verbal communication enrich the relationship among people and enable efforts in supporting understanding, compassion and care for others by mutual agreement. On the scale of life values of Serbian citizens health holds the first position. Immediately following the health issue is good relationship in the family. As healthcare is not only the task of healthcare services, but also of each individual, family and the society as a whole, it is on healthcare personnel to educate the citizens how to preserve and improve their own health and the health of their family by a continual healthcare and education. Above all, this concerns avoidance of bad habits, such as smoking, immoderate alcohol consumption, narcotic abuse, physical inactivity, hypercaloric nutrition, etc. Also, it is significant to make an early recognition of disease symptoms and to turn for

  1. Periodic paralysis: rare presenting symptom of thyrotoxicosis. (United States)

    Correa-Luna, Luis Daniel; Reyes-Ortiz, Luis M; Ramírez-Rivera, José


    Paralysis due to hypokalemia results from an acute shift of potassium into cells or excessive potassium deficit. In the absence of potassium deficit, it is observed in Familial Hypokalemic Periodic Paralysis and in Thyrotoxic Hypokalemic Periodic Paralysis (TPP). This report describes the initial presentation of hyperthyroidism as sudden quadriplegia associated with hypokalemia. A healthy 25-year-old Puerto Rican policeman came to the emergency room with sudden paralysis in the four extremities of five hours evolution. He woke up in the morning and could not get up. The day before admission his legs felt weak, and it was hard to get out of bed. He arrived home at 7:00 PM, ate pasta and vegetables, and went to sleep at 10:00 PM. He had no diarrhea or weight loss, no history of medications or illicit drugs. He has a cousin and an aunt with the diagnosis of hypo-thyroidism. The admission temperature was 36.0 degrees C, pulse 96 per minute, respiratory rate 18 per minute, blood pressure 160/70 mmHg. He was alert and oriented as to time, place and person. He could talk properly and was in no respiratory distress. He had no exophtalmos or lid lag. The thyroid was not enlarged or tender. No pseudoclubbing or pretibial edema was found. There was flaccid paralysis of all extremities, 0/5 legs and 1/5 arms. Deep tendon reflexes could not be elicited. The cranial nerves and sensory examination were normal. The hemogram was within normal limits as were the renal and liver functions. Serum sodium was 140 mEq/L, potassium 1.48 mEq/L, phosphorus 1.4 mEq/L. A random glucose was 155 mg/dl and the arterial Ph was 7.41. The urine potassium was 7.04 mEq/L, sodium 60.8 mg/dl. TSH levelwas < 0.03 ug/d], TUP 50.69% (24-40%), T4 17.6 ug/dl (4.7-11.4 ug/dl) Free T4 Index 28.23. He was managed with intravenous potassium chloride, 80 mEq in a period of seven hours with cardiac monitor. The serum potassium level, after the infusion was completed, was 6.70 mEq/L. No cardiac arrhythmia was

  2. Family planning education. (United States)

    Hamburg, M V


    17 days were spent devoted to the effort of learning about China's educational approach to family planning in the hope of discovering how they are achieving their remarkable success in reducing population growth. As a member of the 1981 New York University/SIECUS Colloquim in China, it was necessary to rely on the translation provided by the excellent guides. Discussions were focused on questions prepared in advance about the topics that concerned the group. These observations, based on a short and limited exposure, cover the following areas: marriage and family planning policies; the family planning program; school programs; adult education; family planning workers; and unique aspects of the program. China has an official position on marriage and family planning that continues to undergo revisions. The new marriage law sets the minimum ages of marriage at 22 for men and 20 for women. Almost everyone marries, and an unmarried person over age 28 is a rarity. The family planning program in China is carried out by an extensive organizational network at national, provincial, and local government levels. Officials termed it a "propaganda campaign." Hospitals, clinics, and factories invariably displayed posters; a popular set of four presents the advantages of the 1 child family as follows: late marriage is best, for it allows more time to work and study; 1 child is best for the health of the mother; one gets free medical care for his/her child if a family has only 1 child; and there is more time to teach 1 child. The state operated television regularly explains the 1 child policy utilizing special films. According to 1 family planning official, "before marriage there is little sex." There are few abortions for unmarried women. Education about sex is for adults, for those persons who are about to be married. There is little if any sex education in schools. Sexual teaching is not generally acceptable, especially in the rural areas. By contrast, in Shanghai the physiology

  3. Family functioning in two treatments for adolescent anorexia nervosa. (United States)

    Ciao, Anna C; Accurso, Erin C; Fitzsimmons-Craft, Ellen E; Lock, James; Le Grange, Daniel


    Family functioning impairment is widely reported in the eating disorders literature, yet few studies have examined the role of family functioning in treatment for adolescent anorexia nervosa (AN). This study examined family functioning in two treatments for adolescent AN from multiple family members' perspectives. Participants were 121 adolescents with AN ages 12-18 from a randomized-controlled trial comparing family-based treatment (FBT) to individual adolescent-focused therapy (AFT). Multiple clinical characteristics were assessed at baseline. Family functioning from the perspective of the adolescent and both parents was assessed at baseline and after 1 year of treatment. Full remission from AN was defined as achieving both weight restoration and normalized eating disorder psychopathology. In general, families dealing with AN reported some baseline impairment in family functioning, but average ratings were only slightly elevated compared to published impaired functioning cutoffs. Adolescents' perspectives on family functioning were the most impaired and were generally associated with poorer psychosocial functioning and greater clinical severity. Regardless of initial level of family functioning, improvements in several family functioning domains were uniquely related to full remission at the end of treatment in both FBT and AFT. However, FBT had a more positive impact on several specific aspects of family functioning compared to AFT. Families seeking treatment for adolescent AN report some difficulties in family functioning, with adolescents reporting the greatest impairment. Although FBT may be effective in improving some specific aspects of family dynamics, remission from AN was associated with improved family dynamics, regardless of treatment type. © 2014 Wiley Periodicals, Inc.

    Franken, E.A.; Driscoll, C.E.; Berbaum, K.S.; Smith, W.L.; Sato, Y.; Kao, S.C.; Steinkraus, L.


    This study evaluated the role of teleradiology (TR) in providing radiology consultation to a family practice center. All radiographs obtained in the center over a 5-month period were read twice independently: once by TR and once with the original radiograph. Accuracy was comparable for TR and plain films, with an average error rate of 7%. Effect of the radiologist's consultation on the family practitioner was substantial, causing changes in the confidence of diagnosis in over half of cases, and in treatment or prognosis in others. The immediate TR report tended to have a greater impact than the late consultation. The authors conclude that TR offers an acceptable mechanism for radiologic consultation

  9. Gender and family stability

    Directory of Open Access Journals (Sweden)


    Full Text Available The increasing trend of partnership disruption among families with children in recent decades has been accompanied by substantial changes in traditional gender roles in industrialized countries. Yet, relatively little is known about the effects of changing gender relations on family stability in the European context. In this paper, we study such gender influences at the familial and societal level in Sweden and Hungary between the mid-1960s and the early 1990s. We focus on the disruption of the first parental union (i.e. the union in which a couple's first child was born. Our analysis is based on data extracted from the Swedish and Hungarian Fertility and Family Surveys of 1992/93. We use the method of hazard regression. The results suggest (i that the establishment of the dual-earner family model influences family stability only if it is accompanied by some changes in traditional gender relations within the family, and (ii that women's and men's labor-market behavior have different effects in spite of the relatively long history of women's (also mothers' labor-force participation in both Sweden and Hungary.

  10. Sirenomelia and caudal malformations in two families. (United States)

    Gerard, Marion; Layet, Valérie; Costa, Teresa; Roumazeilles, Yves; Chenal, Pierre; Cailliez, Daniel; Gerard, Bénédicte


    We report on two families with co-occurrence of sirenomelia and caudal malformations. In the first family, the mother had undergone surgery for a short form of imperforate anus. Her first pregnancy was terminated because of bilateral renal agenesis with oligohydramnios. Her second pregnancy was interrupted because of sirenomelia. The second family was referred to us because of caudal malformation in their two children. The parents' spinal radiographs were normal. The first pregnancy resulted in a girl with imperforate anus, absence of S3-S5 and coccyx, abnormal pelvic floor, and an almost bifid anteriorly located bladder. The second pregnancy resulted in a baby girl with sirenomelia. No diabetes was present during the pregnancies in either of these two families. These families confirm the hypothesis that major genes are responsible for the embryogenesis of the caudal part of the embryo, with variable expression, as has been already described in sirenomelia mouse models (CYP26A1, BMP7/tsg). Molecular studies are underway in these families and in sporadic cases in our laboratory to explore the genetic basis of sirenomelia in humans. Copyright © 2012 Wiley Periodicals, Inc.

  13. Periodic weather and climate variations

    International Nuclear Information System (INIS)

    Ivanov, Vladimir V


    Variations in meteorological parameters are largely due to periodic processes and can be forecast for several years. Many such processes are related to astronomical factors such as the gravitational influences of the Moon and the Sun, and the modulation of solar irradiance by lunar and planetary motion. The Moon, Jupiter, and Venus have the strongest effect. These influences produce lines in the spectra of meteorological variations, which are combinations of the harmonics of the frequencies of revolution of the planets, the Earth, and the Moon around the Sun with the harmonics of the lunar revolution around the Earth. Due to frequency differences between the orbital and radial motions, fine spectral features of three types appear: line splitting, line-profile complications due to radial oscillations, and additional lines due to the combination of radial-oscillation frequencies with perturbation harmonics.

  14. The periodic table in Flatland

    International Nuclear Information System (INIS)

    Kibler, M.


    The D-dimensional Coulomb system serves as a starting point for generating generalized atomic shells. These shells are ordered according to a generalized Madelung rule in D dimensions. This rule together with an Aufbau Prinzip is applied to produce a D-dimensional periodic table. A model is developed to rationalize the ordering of the shells predicted by the generalized Madelung rule. This model is based on the introduction of an Hamiltonian, invariant under the q-deformed algebra U q (so(D)), that breaks down the SO (D + 1) dynamical symmetry of the hydrogen atom in D dimensions. The D = 2 case (Flatland) is investigated with some details. It is shown that the neutral atoms and the (moderately) positive ions correspond to the values q = 0.8 and q = 1, respectively, of the deformation parameter q. (authors). 55 refs

  15. Periodic folding of viscous sheets (United States)

    Ribe, Neil M.


    The periodic folding of a sheet of viscous fluid falling upon a rigid surface is a common fluid mechanical instability that occurs in contexts ranging from food processing to geophysics. Asymptotic thin-layer equations for the combined stretching-bending deformation of a two-dimensional sheet are solved numerically to determine the folding frequency as a function of the sheet’s initial thickness, the pouring speed, the height of fall, and the fluid properties. As the buoyancy increases, the system bifurcates from “forced” folding driven kinematically by fluid extrusion to “free” folding in which viscous resistance to bending is balanced by buoyancy. The systematics of the numerically predicted folding frequency are in good agreement with laboratory experiments.

  16. A periodic table for cancer. (United States)

    Epstein, Richard J


    Cancers exhibit differences in metastatic behavior and drug sensitivity that correlate with certain tumor-specific variables such as differentiation grade, growth rate/extent and molecular regulatory aberrations. In practice, patient management is based on the past results of clinical trials adjusted for these biomarkers. Here, it is proposed that treatment strategies could be fine-tuned upfront simply by quantifying tumorigenic spatial (cell growth) and temporal (genetic stability) control losses, as predicted by genetic defects of cell-cycle-regulatory gatekeeper and genome-stabilizing caretaker tumor suppressor genes, respectively. These differential quantifications of tumor dysfunction may in turn be used to create a tumor-specific 'periodic table' that guides rational formulation of survival-enhancing anticancer treatment strategies.

  17. IDEA and Family Involvement

    Directory of Open Access Journals (Sweden)

    Mehmet Emin Öztürk


    Full Text Available Individuals with Disabilities Education Act (IDEA gives many rights to parents with special needs in terms of involvement and participation. Given the importance of family involvement in the special education process, and federal legislation that increasingly mandated and supported such involvement over time, considerable research has focused on the multiple ways that relationships between schools and families in the special education decision making process have played out. Educational professionals should create a positive climate for CLD families so that they feel more comfortable and therefore are able to participate more authentically and meaningfully.

  18. Families of vicious walkers

    International Nuclear Information System (INIS)

    Cardy, John; Katori, Makoto


    We consider a generalization of the vicious walker problem in which N random walkers in R d are grouped into p families. Using field-theoretic renormalization group methods we calculate the asymptotic behaviour of the probability that no pairs of walkers from different families have met up to time t. For d > 2, this is constant, but for d -α , which we compute to O(ε 2 ) in an expansion in ε = 2 - d. The second-order term depends on the ratios of the diffusivities of the different families. In two dimensions, we find a logarithmic decay (ln t) -α-bar and compute α-bar exactly

  20. Further results on periods and period doubling for iterates of the trapezoic function

    International Nuclear Information System (INIS)

    Beyer, W.A.; Stein, P.R.


    The trapezoidal function lambda f/sub e/(x), is defined for fixed e element of (0,1] and for lambda element of [1,2] by lambda f/sub e/ (x) = lambda for /x-1/< 1-e and lambda f/sub e/(x) = lambda(1-/x-1/)/(1-e) for 1 greater than or equal to /x-1/greater than or equal to 1-e. For a fixed e, this is a one parameter family of endomorphisms of the interval [0,2]. The structure of the periods (or cycles) of these mappings is studied. In addition, the metric properties of the corresponding bifurcation diagrams are considered; in particular, the rate of convergence of a sequence of bifurcation points in the (x,lambda) plane is studied. It is shown to be different from that found by Feigenbaum and others for mappings which are not flat at the top. The limiting case e = 1 is of special interest. For cycles and containing a point x element of[e,2-e], the period quadruplicates instead of doubling as it does in the usual case

  1. Family and marital affairs in 19th century Serbia

    Directory of Open Access Journals (Sweden)

    Divac Zorica


    Full Text Available Ethnology, as a science, continues to dedicate very much attention to the traditional culture of Serbian 19th century villages. In the past, material culture with all of the disappearing, relic artifacts no longer in use was in the focus of the science. A large amount of data was gathered, on the population origins, migrations, beliefs, rituals, social institutions such as cooperative associations and so on. In spite of these data, ethnology today has no detailed knowledge on life of Serbian 19th century villages especially there is a gap in our knowledge on family life in the first half of the 19th century. Family researches, such as ethnologists, sociologists and particularly those that deal with transformations, in their analyses use as a variable the so-called patriarchal-traditional model of the family. The model assumes: extended or cooperative family, stable and directed toward maintaining family ties and property; divorce is rare since the marriage itself is founded on duties toward family group and deference for a husband or father; the family is tied down to its land and family ties with male lineage are encouraged, and so on. In the first half of the 19th century however, Serbia was the battle-field of political turmoil, rebellion fights and huge social changes and general attitude of instability, migrations arguments, Turkish aggression, and frequent governmental changes, which brought about disturbance in patriarchal system, customs and regulations. Archival sources from the period reveal that courts were very busy dealing with cases of family and marital issues. It is evident that the regulations were put forward to enhance family solidity through marriage and family stability. Several available examples show "a dark side" of the Serbian family life of the period; today, it is not possible to establish the degree to which the family transformed itself from a patriarchal to a more liberated one.

  3. Family medical leave as a resilience resource for family caregivers. (United States)

    Swanke, Jayme; Zeman, Laura Dreuth


    Case managers mobilize family networks to care for patients. Family medical leave can be a resource for case managers who seek to enhance resilience among family caregivers. The Family Medical Leave Act, passed in 1993, was the first U.S. policy to regulate employee leaves from work for family care purposes (29 CFR 825.102). This policy offers family caregivers increased flexibility and equality. Current and emerging policies also can reduce financial strain. The discussion examines how case managers can integrate family medical leave into best-practice models to support patients and family caregivers.

  5. Familial polycystic ovarian disease. (United States)

    Givens, J R


    Emphasis is placed on the heterogeneity of the phenotypic presentation of PCOD. It is the common expression of an unknown number of disorders and thus is a sign and not a specific diagnosis. Two essential features are arrested follicular maturation and atresia of follicles. Normal folliculogenesis is described, emphasizing that a large number of areas could be subject to derangement causing PCOD. Any interference of the finely balanced sequence of events can lead to PCOD. The genetic defect causing familial PCOD is unknown and the initiating event remains undefined. Three families are described that illustrate four features of familial PCOD. A number of associated disorders such as diabetes, hyperinsulinemia, obesity, and hypertension are described. The potential importance of agents that modulate the LH and FSH activity that may cause PCOD is emphasized. The theoretic means by which similar male and female gonadal abnormalities may be coupled in families through growth factors EGF and alpha TGF are presented.

  13. Adolescent attachment, family functioning and depressive symptoms

    Directory of Open Access Journals (Sweden)

    Nishola Rawatlal


    Full Text Available Background. Adolescence represents a challenging transitional period where changes in biological, emotional, cognitive and social domains can increase the risk of developing internalised problems including subthreshold depression. Adolescent-parent attachment style, perceived support and family functioning may increase risk for depressive symptoms or may reduce such risk. Adolescent-parent attachment, adolescent-perceived support from parents and family functioning were examined as correlates of depressive symptom presentation within this age group. Methods. Participants included a maternal parent and an adolescent (65.5% female from each family. Adolescents were in Grade 7 (n=175 or Grade 10 (n=31. Data were collected through home interviews. The Self-Report of Family Inventory (SFI, Experiences of Close Relationships Scale (ECR, Network of Relationships Inventory (NRI, Children’s Depression Inventory (CDI and Child Behavior Checklist (CBCL were used to assess depression, parental support and attachment.  Results. Two models were examined: one with adolescent report of depressive symptoms as the outcome and a second with parent report of adolescent internalising symptoms as the outcome. The model predicting adolescent-reported depressive symptoms was significant with older age, higher levels of avoidant attachment, and higher levels of youth-reported dysfunctional family interaction associated with more depressive symptomatology. In the model predicting parent report of adolescent internalising symptoms only higher levels of dysfunctional family interaction, as reported by the parent, were associated with higher levels of internalising symptoms. Conclusion. Positive family communication, cohesion and support predictive of a secure parent-adolescent attachment relationship reduced the risk of a depressive symptom outcome. Secure adolescents were able to regulate their emotions, knowing that they could seek out secure base attachment relations

    Full Text Available SUMMARY: The objective of this study was to identify the scientific article about the care of nursing to the family, published in periodic of Brazilian nursing, index-linked article survey to the LILACS, in the period of 1993 the 2003, and to analyze them how much to the concept and composition of the families, systematization and proposals of action of nursing and formation and qualification of the authors. In the results we find in 10 years (1993-2003, 9 publications concerning nursing in family. Where we can find the predominance of works that focus the systematization and proposals of action, evidencing of a general form, a lack of studies in the area of nursing in family, where the Program of Health of the Family appears as principal source of promotion of care of nursing to the family and motivation for studies that approach this thematic one. All research had had as authorship nurses doctors, masters and specialists, which acted as professors. KEY WORDS: Assistance to the Family; Health of the Family and Nursing and Family.

  1. [Family, Suicide and Mourning]. (United States)

    Garciandía Imaz, José Antonio


    Death is an event that always breaks into family life in a surprising way. Of all the deaths, suicide is the one which more strongly questions the functionality of a family and increases the risk of difficulties in the mourning process. Families in which a suicide has occurred are exposed to a greater possibility of disintegration, disorganization and pathological expressions in their members. To present a reduced and circumscribed narrative revision, restricted to examine the relationship between suicide and the mourning process in the family. The suicide of a loved one is an event that may contribute to pathological grief and mental dysfunctions in surviving relatives. Death in the family is a natural phenomenon. However, death by suicide is one of the phenomena that can generate more alterations in the structure and organization of the family, due to the difficulty related to the mourning process.

  2. Mandolin Family Instruments (United States)

    Cohen, David J.; Rossing, Thomas D.

    The mandolin family of instruments consists of plucked chordophones, each having eight strings in four double courses. With the exception of the mandobass, the courses are tuned in intervals of fifths, as are the strings in violin family instruments. The soprano member of the family is the mandolin, tuned G3-D4-A4-E5. The alto member of the family is the mandola, tuned C3-G3-D4-A4. The mandola is usually referred to simply as the mandola in the USA, but is called the tenor mandola in Europe. The tenor member of the family is the octave mandolin, tuned G2-D3-A3-E4. It is referred to as the octave mandolin in the USA, and as the octave mandola in Europe. The baritone member of the family is the mandocello, or mandoloncello, tuned C2-G2-D3-A3. A variant of the mandocello not common in the USA is the five-course liuto moderno, or simply liuto, designed for solo repertoire. Its courses are tuned C2-G2-D3-A3-E4. A mandobass was also made by more than one manufacturer during the early twentieth century, though none are manufactured today. They were fretted instruments with single string courses tuned E1-A1-D2-G2. There are currently a few luthiers making piccolo mandolins, tuned C4-G4-D5-A5.

  3. Dynamical diffraction in periodic multilayers

    CERN Document Server

    Sears, V F


    Exact reflectivity curves are calculated numerically for various periodic multilayers using the optical matrix method in order to test the dynamical theory of diffraction. The theory is generally valid for values of the bilayer thickness d up to about 100 A. For somewhat larger values of d, where the theory begins to break down, the initial discrepancy is in the phase of the oscillations in the wings of the peaks. For very large values of d, where the first-order Bragg peak approaches the edge of the mirror reflection, two general types of multilayers can be distinguished. In the first (typified in the present work by Ni/Ti), there is a large (30% or more) reduction in the actual value of the critical wave vector for total reflection while, in the second (typified here by Fe/Ge), there is very little reduction (3 % or so). The origin of these two very different types of behavior is explained. It is also shown that, within the dynamical theory of diffraction, the change in the position of the center of the Dar...

  4. "Not a Real Family": Microaggressions Directed toward LGBTQ Families. (United States)

    Haines, Kari M; Boyer, C Reyn; Giovanazzi, Casey; Galupo, M Paz


    The present study investigates microaggressions toward individuals in lesbian, gay, bisexual, transgender, and queer (LGBTQ) families. Microaggressions are subtle forms of discrimination experienced on a daily basis as verbal or behavioral slights against individuals in oppressed groups. LGBTQ microaggressions are often studied at an individual level and understood as being directed toward an individual based on perceived identity. The present study allows for an understanding of bias directed at the family system level. Participants included 46 adults who identified as being part of an LGBTQ family. Participants completed an online questionnaire and described their experiences of LGBTQ family microaggressions. Thematic analysis revealed that LGBTQ family microaggressions were salient to individuals across multiple family roles. Three specific themes emerged: family legitimacy, conflicts with family values, and gender violation within family. These findings highlight the way LGBTQ microaggressions are influenced by cultural notions of family and impact the family system.

  9. Changing families, changing workplaces. (United States)

    Bianchi, Suzanne M


    American families and workplaces have both changed dramatically over the past half-century. Paid work by women has increased sharply, as has family instability. Education-related inequality in work hours and income has grown. These changes, says Suzanne Bianchi, pose differing work-life issues for parents at different points along the income distribution. Between 1975 and 2009, the labor force rate of mothers with children under age eighteen increased from 47.4 percent to 71.6 percent. Mothers today also return to work much sooner after the birth of a child than did mothers half a century ago. High divorce rates and a sharp rise in the share of births to unmarried mothers mean that more children are being raised by a single parent, usually their mother. Workplaces too have changed, observes Bianchi. Today's employees increasingly work nonstandard hours. The well-being of highly skilled workers and less-skilled workers has been diverging. For the former, work hours may be long, but income has soared. For lower-skill workers, the lack of "good jobs" disconnects fathers from family obligations. Men who cannot find work or have low earnings potential are much less likely to marry. For low-income women, many of whom are single parents, the work-family dilemma is how to care adequately for children and work enough hours to support them financially. Jobs for working-class and lower middle-class workers are relatively stable, except in economic downturns, but pay is low, and both parents must work full time to make ends meet. Family income is too high to qualify for government subsidized child care, but too low to afford high-quality care in the private market. These families struggle to have a reasonable family life and provide for their family's economic well-being. Bianchi concludes that the "work and family" problem has no one solution because it is not one problem. Some workers need more work and more money. Some need to take time off around the birth of a child

  11. Family therapy in treatment of the deaf: a case report. (United States)

    Shapiro, R J; Harris, R I


    Deaf patients with psychological problems have developmental handicaps and clinical characteristics that reduce the effectiveness of traditional modes of psychotherapy. Attempts have been made to utilize individual and group therapy, but family therapy has been largely overlooked as a method of alleviating problems of the deaf. Clinical and research writings provide us with rich insights into the family dynamics of the deaf. These data suggest to the authors that the problems of deaf individuals are largely related to family problems, and therefore merit a family orientation as the focus for treatment. This paper describes an attempt to apply family therapy with a range of deaf patients over a period of two years. From a review of their work, the authors conclude that family therapy can be effective, particularly in the treatment of deaf adolescents and children.

  12. Population estimates of extended family structure and size. (United States)

    Garceau, Anne; Wideroff, Louise; McNeel, Timothy; Dunn, Marsha; Graubard, Barry I


    Population-based estimates of biological family size can be useful for planning genetic studies, assessing how distributions of relatives affect disease associations with family history and estimating prevalence of potential family support. Mean family size per person is estimated from a population-based telephone survey (n = 1,019). After multivariate adjustment for demographic variables, older and non-White respondents reported greater mean numbers of total, first- and second-degree relatives. Females reported more total and first-degree relatives, while less educated respondents reported more second-degree relatives. Demographic differences in family size have implications for genetic research. Therefore, periodic collection of family structure data in representative populations would be useful. Copyright 2008 S.

  13. Are Family Firms Better Performers during Financial Crisis?

    Zhou, Haoyong

    (Italy) during the period 2006-2010, I give empirical evidences examining the performance of family firms vis-à-vis non-family firms during the current financial crisis. I find that broadly defined family firms, comprising 35 percent of the sample, do not outperform non-family firms during the crisis...... that in the financial crisis, founder firms bear the least agency cost and Tobin’s Q is not a good measure of corporate performance.......Despite extensive researches on efficiency of family firms in normal or good economic times, we know rather little about whether family firms are superior performers in recession times. Using a dataset covering firms from S&P 500 (US), FTE100 (UK), DAX 30 (Germany), CAC 40 (France) and FTSE MIB 40...

  14. Family First? The Costs and Benefits of Family Centrality for Adolescents with High-Conflict Families. (United States)

    Yuen, Cynthia X; Fuligni, Andrew J; Gonzales, Nancy; Telzer, Eva H


    Youth who do not identify with or value their families (i.e., low family centrality) are considered to be at risk for maladjustment. However, the current study investigated whether low family centrality may be adaptive in negative family contexts (i.e., high family conflict) because youth's self-worth should be less tied to the quality of their family relationships. Multilevel models using daily diaries and latent variable interactions using longitudinal questionnaires indicated that, among a sample of 428 Mexican American adolescents (49.8% male, M age  = 15.02 years), lower family centrality was generally detrimental to youth's well-being. However, for youth in adverse family environments, low family centrality ceased to function as a risk factor. The present findings suggest that family centrality values play a more nuanced role in youth well-being than previously believed, such that low family centrality may be an adaptive response to significant family challenges.

  3. Who counts as family? Family typologies, family support, and family undermining among young adult gay and bisexual men. (United States)

    Soler, Jorge H; Caldwell, Cleopatra H; Córdova, David; Harper, Gary; Bauermeister, José A


    Gay and bisexual men may form chosen families in addition to or in place of families of origin. However, the characteristics of these diverse families remain largely unexamined in the quantitative literature. The purpose of this study was to develop a family typology based on responses from a racially and ethnically diverse sample of young adult gay and bisexual men (YGBM) recruited from the Detroit Metropolitan Area (N=350; 18-29 years old). To explore the role of family, we then examined family social support and social undermining in relation to YGBM psychological distress within different family types. A series of multivariate regressions were used to examine associations between family social support and social undermining with depression and anxiety outcomes. The majority (88%) of YGBM included family of origin in their definitions of family and 63% indicated having chosen families. Associations between family social processes and psychological outcomes varied by type of family, suggesting that family composition shapes how perceptions of support and undermining relate to experiencing symptoms of depression and anxiety. Chosen families play a prominent role in the lives of YGBM and should not be overlooked in family research. Findings also highlight the importance of examining co-occurring family social support and social stress processes to further address psychological distress symptoms among YGBM.

  6. Construction of a Family Quality of Life Support Program for families of young and adults with intellectual disability

    Directory of Open Access Journals (Sweden)



    Full Text Available This paper is grounded on current conceptions on Family Quality of Life (FQoL and family-centered intervention. It describes a part of the building process of a ‘Program for Supporting Family Quality of Life’, within the SAIOA-BBK frame a Gorabide’s information, guidance and support service for people with intellectual disability and their families. A major goal of this project is making proposals for professionals to fit the link between FQoL assessment and its improvement. The program was developed, constructed and tested through collaborative methods between professionals and university researchers, aiming to an increase of FQoL of families with sons or daughters among the youth and adulthood period. Program features, and how it was experimented in a pilot sample of families (n = 5 is presented.

  7. Family functioning in the families of psychiatric patients: a comparison with nonclinical families. (United States)

    Trangkasombat, Umaporn


    To examine family functioning in the families of psychiatric patients. Families of psychiatric patients and nonclinical families were compared. There were 60 families in each group. The instrument included a semistructured interview of family functioning and the Chulalongkorn Family Inventory (CFI), a self-report questionnaire designed to assess the perception of one's family. From the assessment by semistructured interview, 83.3% of psychiatric families and 45.0% of nonclinical families were found to be dysfunctional in at least one dimension. The difference was statistically significant (p dysfunctional dimensions in the psychiatric families was significantly higher than in the nonclinical control group, 3.5 +/- 1.9 and 0.98 +/- 1.5 respectively, p families were significantly lower than the control group, reflecting poor family functioning. The dysfunctions were mostly in the following dimensions: problem-solving, communication, affective responsiveness, affective involvement, and behavior control. Psychiatric families faced more psychosocial stressors and the average number of stressors was higher than the control families, 88.3% vs. 56.7% and 4.2 +/- 2.7 vs. 1.3 +/- 1.47 stressors respectively, p < 0.0001. Family functioning of psychiatric patients was less healthy than the nonclinical control. The present study underlined the significance of family assessment and family intervention in the comprehensive care of psychiatric patients.

  8. Attitudes toward family planning. (United States)

    Gille, H


    Many of the 135 countries participating in the 1974 UN World Population Conference were far from accepting the basic human right to decide freely and responsibly the number and spacing of their children and to have the information, education, and means to do so. Considerable progress has been made since then, and the number of developing countries that provide direct government support for family planning has increased to over 60%. Many have liberalized laws and regulations which restricted access to modern contraceptive methods, and a growing number provide family planning services within their health care programs. A few have recognized the practice of family planning as a constitutional right. In late 1983 at the Second African Population Conference, recognition of family as a human right was strongly contested by several governments, particularly those of West Africa. in developed countries most of the women at risk of unwanted pregnancy are using contraceptives. Of the major developing regions the highest use level is in Latin America, wherein most countries 1/3 to 1/2 of married women are users. Levels in Asian countries range from up to 10% in Afghanistan, Nepal, and Pakistan to up to 40% in the southeastern countries. China, a special case, now probably exceeds an overall use level of 2/3 of married women. Contraceptive use is lowest in Africa. There is room for improvement even among many of the successful family planning programs, as access to contraceptives usually is not sufficient to overcome limiting factors. To ensure the individual's free choice and strengthen the acceptability and practice of family planning, all available methods should be provided in service programs and inluded in information and education activities. Family planning programs should engage local community groups, including voluntary organizations, in all aspects of planning, management, and allocation of resources. At the government level a clear political commitment to family

    Estevez-Rams, E.


    Full text: The discovery of the quasi-crystals [D. Schechtman et. Al., Phys.] Rev. Lett. [53, 1951-1953 (1984)] made very narrow definition of the crystalline state based on the periodicity of a local arrangement of atoms. Since the definition of this State has been a matter of much controversy [G.R. Desiraju, Nature 423, 485 (2003); S. van Smaalen, IUCR Aperiodic Commission Reports. August 7, 2002; International Union of Crystallography. Report of the Executive Committee for 1991; ACTA Cryst. A48, 922-946 (1992)]. We will make a presentation of the current time of the crystallography in this regard from the conceptual point of view. We show the use of the formalism of algorithmic complexity or Kolmogorov [M. Li and P. Vitanyi, An Introduction to Kolmogorov Complexity and Its Applications (Springer Verlag, Heidelberg, 1993), W.H. Zurek, Phys.] Rev. 40, 4731 (1989); Nature 341, 119-124 (1989)] provides a different perspective on the nature of the Crystallographic order. Infinite crystals can be considered solid with zero algorithmic complexities by atom. Show statistical analysis of inorganic compounds [J.L.C. Daams et al., Atlas of Crystal Structure Types for Intermetallic Phases (ASM International, Ohio, 1991), Fachinformationszentrum/NIST Inorganic Crystal Structure Database, Karlsruhe (2003)] demonstrating that the minimization of complexity is a trend in the crystalline arrangement. We will then compare the degree of disorder of some typical solids according to their algorithmic complexity. Finally, space diffraction will be studied from this same perspective and will be discussed that zero algorithmic complexities by point in space of diffraction does not necessarily imply the same thing for the Atomic arrangement. The discrete portion of the diffraction pattern is a fingerprint of the underlying order but not the actual existence of long-range order. Experimental results will be showcased [E.

    Full Text Available Gender stereotyping and gender role development is one of the debatable concerns to sociologists especially those who are interested in sociology of gender. This study attempts to investigate the role of family inculcating gender stereotyping in Pakhtun culture and its impact on gender role development conducted in public-sector universities of Malakand Division, Khyber Pakhtunkhwa province of Pakistan. The data were collected through in-depth interview method using interview guide as a tool of data collection. A sample size of 24 respondents consisting male and female students and teachers (8 samples from each university through purposive sampling technique was selected from three universities in the region, that is, University of Malakand, University of Swat, and Shaheed Benazir Bhutto University Sharingal (main campus. The collected information has been analyzed qualitatively where primary information has been linked with secondary data for further elaboration and attainment of grounded facts. The study reveals that gender stereotyping and gender role formation are sociocultural and relational constructs, which are developed and inculcated in the institutional network, social interaction, and social relationships especially in family. The study indicated that in family sphere, gender stereotyping and gender role formation are the outcome of gender socialization, differential familial environment, and parents’ differential role with children. The study recommends that gender-balanced familial environment, adopting the strategy of gender mainstreaming and positive role of media, can overcome gender stereotyping and reduce its impacts on gender and social role formation.

  11. Egypt boosts family planning. (United States)


    A $4 million Agency for International Development (AID) agreement was signed in Cairo September 30 which will help the Egyptian government increase family planning services. The project is in response to a request for up to $17 million of AID funds for family planning programs during the next 3 years. The funds will pay for: contract advisors to provide short-term in-country training of physicians, architectural and engineering services to renovate a hospital for family planning and obstetrics/gynecology training, and a field training site for family planning service providers. Some Egyptians will receive training in specialized areas in the U.S. and other countries. More than $1.5 million of the $4 million will finance local costs of goods and services required. In addition, it is anticipated that U.S.-owned local currencies will be obligated for direct support of U.S. technical personnel. Over the 3-year life of the project the $17 million from AID plus $664,000 of U.S.-owned local currency will cover 44% of the total costs of selected Egyptian family planning activities. The Egyptian government will contribute at least $18.4 million and the U.N. Fund for Population Activities and the International Bank for Reconstruction and Development will contribute $4.3 million.

  12. Family focused nursing education

    Directory of Open Access Journals (Sweden)

    R. A. E. Thompson


    Full Text Available At the present time the majority of nurse education programmes are firmly tied to the perspectives of curative medicine within hospitals - they are disease and hospital oriented. This model, which indicates a 'sickness’ concept of nursing is entirely inappropriate if contemporary and future health care needs are to be met. The shift in education should be towards a health, family and whole person centered approach. The family is the most fundamental and dynamic unit in society with a profound influence upon its members. Besides performing a variety of other functions, the family has a central role in promoting and maintaining the health of its members. Because the family unit is the microcosm of society and accurately reflects the needs of society at large it is appropriate that this should be a key area of experience. Family attachments during training provide opportunities for close and committed contact with people in their everyday world and for learning what is really important to them.

  14. Family Impacts on Self-Esteem in Chinese College Freshmen. (United States)

    Shi, Jingyu; Wang, Lu; Yao, Yuhong; Su, Na; Zhao, Xudong; Chen, Fazhan


    This study examined the impact of family function and family-related factors, such as being an only child, grandparenting, income, and family relationship on the self-esteem in college students who are in the transitional period from late adolescence to emerging adulthood. The participants were 2001 Chinese college freshmen with the age from 16 to 20 years. Data were collected by using the family assessment device (FAD), the Rosenberg Self-esteem Scale, and self-report of family information. Comparison analysis indicated that the students from one child families, harmonious families, from families with higher income, or raised by their parents without the experience of grandparenting are more likely to show high self-esteem than their counterparts. Moreover, a multiple regression showed that dimensions of FAD such as role, communication, behavioral control, and problem solving predicted level of self-esteem of the college students, ranging from 13.2 to 17.9% variance. The results of this study showed that the self-esteem of the college freshmen is highly correlated with their family's performance. Therefore, the program focusing on improving family functioning is needed, in order to enhance the self-esteem of the young people and hence contribute to promoting the mental health of them.

  15. Conferences and Family Reunions

    Directory of Open Access Journals (Sweden)

    Sarah Sutherland


    Full Text Available Professional associations and conferences have similarities with and differences from families and family reunions. This comparison can illustrate some ways professional associations can approach the integration of new members and the planning of conferences in order to facilitate membership development and leadership renewal. Unlike family reunions, professional conferences are not closed events that require a shared culture in order to fully participate; they are events that should show the constant change and development of practice that is representative of the profession – for both members and non-members. Some of the topics explored in the article are: making it easy for outsiders to contribute, considering the tastes of new members, making it easy to volunteer in a meaningful way, and remembering who the future of the organization is. These simple considerations will assist in opening professional associations to new participants and help them to maintain their relevance and vitality over time.

  17. Familial gigantiform cementoma

    Energy Technology Data Exchange (ETDEWEB)

    Han, Won Jeong; Kim, Eun Kyung [Dankook Univ. School of Dentistry, Seoul (Korea, Republic of)


    Familial gigantiform cementoma is a rate fibro-cemento-osseous disease of the jaws which appears to be transmitted as an autosomal dominant trait with variable expressivity of the phenotype. A 7-year-old girl visited DKUDH complaining of the painless facial deformity. Clinically, significant facie-lingual expansion was observed at the left maxilla, left mandibular body and symphysis portion. Malposition of lower anterior teeth was found. Panoramic radiograph and CT scan showed the extensive expandile mixed lesion at maxilla and mandible. Bone scan revealed hot spot at the maxilla and left side of mandible. Histologic examination revealed moderately dense fibrous connective tissue with scattered masses resembling cementum. The patient's mother had a history of the mandibular resection due to benign tumor. Her younger brother had buccal expansion of right mandible. We report our finding of a family that has exhibited clinical, radiographic and histologic findings consistent with the familial gigantiform dementoma.

    International Nuclear Information System (INIS)

    Jiang Yu; Dong Shihai; Lozada-Cassou, M.


    We study the resonant response of a nonlinear system to external periodic perturbations. We show by numerical simulation that the periodic resonance curve may anticipate the dynamical instability of the unperturbed nonlinear periodic system, at parameter values far away from the bifurcation points. In the presence of noise, the buried intrinsic periodic dynamics can be picked out by analyzing the system's response to periodic modulation of appropriate intensity

  20. Family environment patterns in families with bipolar children. (United States)

    Belardinelli, Cecilia; Hatch, John P; Olvera, Rene L; Fonseca, Manoela; Caetano, Sheila C; Nicoletti, Mark; Pliszka, Steven; Soares, Jair C


    We studied the characteristics of family functioning in bipolar children and healthy comparison children. We hypothesized that the family environment of bipolar children would show greater levels of dysfunction as measured by the Family Environment Scale (FES). We compared the family functioning of 36 families that included a child with DSM-IV bipolar disorder versus 29 comparison families that included only healthy children. All subjects and their parents were assessed with the K-SADS-PL interview. The parents completed the FES to assess their current family functioning. Multivariate analysis of variance was used to compare the family environment of families with and without offspring with bipolar disorder. Parents of bipolar children reported lower levels of family cohesion (pfamilies where a parent had a history of mood disorders compared to families where parents had no history of mood disorders. Length of illness in the affected child was inversely associated with family cohesion (r=-0.47, p=0.004). Due to the case-control design of the study, we cannot comment on the development of these family problems or attribute their cause specifically to child bipolar disorder. Families with bipolar children show dysfunctional patterns related to interpersonal interactions and personal growth. A distressed family environment should be addressed when treating children with bipolar disorder.

  8. Incarceration in fragile families. (United States)

    Wildeman, Christopher; Western, Bruce


    Since the mid-1970s the U.S. imprisonment rate has increased roughly fivefold. As Christopher Wildeman and Bruce Western explain, the effects of this sea change in the imprisonment rate--commonly called mass imprisonment or the prison boom--have been concentrated among those most likely to form fragile families: poor and minority men with little schooling. Imprisonment diminishes the earnings of adult men, compromises their health, reduces familial resources, and contributes to family breakup. It also adds to the deficits of poor children, thus ensuring that the effects of imprisonment on inequality are transferred intergenerationally. Perversely, incarceration has its most corrosive effects on families whose fathers were involved in neither domestic violence nor violent crime before being imprisoned. Because having a parent go to prison is now so common for poor, minority children and so negatively affects them, the authors argue that mass imprisonment may increase future racial and class inequality--and may even lead to more crime in the long-term, thereby undoing any benefits of the prison boom. U.S. crime policy has thus, in the name of public safety, produced more vulnerable families and reduced the life chances of their children. Wildeman and Western advocate several policy reforms, such as limiting prison time for drug offenders and for parolees who violate the technical conditions of their parole, reconsidering sentence enhancements for repeat offenders, and expanding supports for prisoners and ex-prisoners. But Wildeman and Western argue that criminal justice reform alone will not solve the problems of school failure, joblessness, untreated addiction, and mental illness that pave the way to prison. In fact, focusing solely on criminal justice reforms would repeat the mistakes the nation made during the prison boom: trying to solve deep social problems with criminal justice policies. Addressing those broad problems, they say, requires a greater social

  9. Family Resilience in the Military (United States)

    Meadows, Sarah O.; Beckett, Megan K.; Bowling, Kirby; Golinelli, Daniela; Fisher, Michael P.; Martin, Laurie T.; Meredith, Lisa S.; Osilla, Karen Chan


    Abstract Military life presents a variety of challenges to military families, including frequent separations and relocations as well as the risks that service members face during deployment; however, many families successfully navigate these challenges. Despite a recent emphasis on family resilience, the U.S. Department of Defense (DoD) does not have a standard and universally accepted definition of family resilience. A standard definition is a necessary for DoD to more effectively assess its efforts to sustain and improve family resilience. RAND authors reviewed the literature on family resilience and, in this study, recommend a definition that could be used DoD-wide. The authors also reviewed DoD policies related to family resilience, reviewed models that describe family resilience and identified key family resilience factors, and developed several recommendations for how family-resilience programs and policies could be managed across DoD.

We estimate international donor funding for family planning in 2003-13, the period covering the introduction o...

  13. Thyrotoxic periodic paralysis associated with a mutation in the sodium channel gene SCN4A. (United States)

    Lane, Andrew H; Markarian, Katherine; Braziunene, Ieva


    Thyrotoxic hypokalemic periodic paralysis (THypoKPP) is an uncommon disorder with an unknown etiology. We describe a family in which the proband presented with paralysis and thyrotoxicosis. Because of similarities between familial hypokalemic periodic paralysis (FHypoKPP) and THypoKPP, we sequenced exon 12 of the SCN4A gene, which is known to be mutated in FHypoKPP. We identified an Arg672Ser mutation in the proband and his affected father, as well as the proband's brother. As the brother has paralysis without thyrotoxicosis, our finding suggests that the genetic spectrum of FHypoKPP and THypoKPP overlap. We speculate that thyroid hormone may exert a threshold or permissive effect in hypokalemic periodic paralysis. Non-thyrotoxic family members of individuals with THypoKPP may have an unrecognized risk for paralysis.

  14. Periodic orbits of solar sail equipped with reflectance control device in Earth-Moon system (United States)

    Yuan, Jianping; Gao, Chen; Zhang, Junhua


    In this paper, families of Lyapunov and halo orbits are presented with a solar sail equipped with a reflectance control device in the Earth-Moon system. System dynamical model is established considering solar sail acceleration, and four solar sail steering laws and two initial Sun-sail configurations are introduced. The initial natural periodic orbits with suitable periods are firstly identified. Subsequently, families of solar sail Lyapunov and halo orbits around the L1 and L2 points are designed with fixed solar sail characteristic acceleration and varying reflectivity rate and pitching angle by the combination of the modified differential correction method and continuation approach. The linear stabilities of solar sail periodic orbits are investigated, and a nonlinear sliding model controller is designed for station keeping. In addition, orbit transfer between the same family of solar sail orbits is investigated preliminarily to showcase reflectance control device solar sail maneuver capability.

  15. Periodic Poisson Solver for Particle Tracking

    International Nuclear Information System (INIS)

    Dohlus, M.; Henning, C.


    A method is described to solve the Poisson problem for a three dimensional source distribution that is periodic into one direction. Perpendicular to the direction of periodicity a free space (or open) boundary is realized. In beam physics, this approach allows to calculate the space charge field of a continualized charged particle distribution with periodic pattern. The method is based on a particle mesh approach with equidistant grid and fast convolution with a Green's function. The periodic approach uses only one period of the source distribution, but a periodic extension of the Green's function. The approach is numerically efficient and allows the investigation of periodic- and pseudo-periodic structures with period lengths that are small compared to the source dimensions, for instance of laser modulated beams or of the evolution of micro bunch structures. Applications for laser modulated beams are given.

  18. Another way to teach family: family nursing game

    Directory of Open Access Journals (Sweden)

    Carla Sílvia Neves da Nova Fernandes


    Full Text Available Current paper describes the application of an innovative strategy to teach family, within a hospital context, by sensitizing nurses on the family subject through the use of a game. Given the hospitalization of a relative, the family faces changes in its dynamics caused by the crisis it is exposed to. It is the relevance for including the family within the care process. Since nurses are expected to assume a key role for which they need specific competence to intervene in families when experiencing an eventual crisis. The in-service education becomes a strategy of generating new skills and enhances human capital to improve the quality of nursing care. Considering the importance of including family in the care context, a playful tool called Family Nursing Game has been invented for teaching the family, especially by passing a model of family intervention. The strategy is based on the belief of the existence of relationship between game and learning.

  19. Family interactions in adoptive compared to nonadoptive families. (United States)

    Rueter, Martha A; Keyes, Margaret A; Iacono, William G; McGue, Matt


    Despite the large and growing numbers of adoptive families, little research describes interactions in families with adopted adolescents. Yet, adopted adolescents' increased risk for adjustment problems, combined with the association between family interactions and adolescent adjustment in nonadoptive families, raises questions about differences in adoptive and nonadoptive family interactions. We compared observed and self-reported family interactions between 284 adoptive and 208 nonadoptive families and within 123 families with 1 adopted and 1 nonadopted adolescent. Adolescents averaged 14.9 years of age. Comparisons were made using analysis of variance incorporating hierarchical linear methods in SAS PROC MIXED to control family-related correlations in the data. Parents and children reported more conflict in adoptive families when compared with nonadoptive families. Families with 1 adopted and 1 nonadopted adolescent reported more conflict between parents and adopted adolescents. Observed parental behavior was similar across adoptive and nonadoptive children although adopted adolescents were less warm and, in families with 2 adopted children, more conflictual than nonadopted adolescents. These findings suggest a need for further investigation of the association between family interactions and adopted adolescent problem behavior. Copyright 2009 APA, all rights reserved.

  20. Period mappings with applications to symplectic complex spaces

    CERN Document Server

    Kirschner, Tim


    Extending Griffiths’ classical theory of period mappings for compact Kähler manifolds, this book develops and applies a theory of period mappings of “Hodge-de Rham type” for families of open complex manifolds. The text consists of three parts. The first part develops the theory. The second part investigates the degeneration behavior of the relative Frölicher spectral sequence associated to a submersive morphism of complex manifolds. The third part applies the preceding material to the study of irreducible symplectic complex spaces. The latter notion generalizes the idea of an irreducible symplectic manifold, dubbed an irreducible hyperkähler manifold in differential geometry, to possibly singular spaces. The three parts of the work are of independent interest, but intertwine nicely.

  1. Regional identity and family

    Directory of Open Access Journals (Sweden)

    Tripković Gordana D.


    Full Text Available This paper is a continuation of a study on regionalisation and family, within the project named Sociological Aspects of Multiculturality and Regionalisation and their influence on the development of AP Vojvodina and the Republic of Serbia. The author focuses her attention to operationalisation of the theoretical and methodological premises that were developed in the previous paper (Tripković, 2002: 111-127, which means that it represents the results of the second phase of the research plan. This phase includes adjusting of theoretical concepts to the fieldwork displaying the results of the research and the analysis of the findings that put a family in the context of confronting different identities, above all national and regional. As possible "identity difference" was emphasized in the research, theoretical and methodological apparatus was adjusted to this goal. That is why in this paper the replies of interviewees that can suggest or reject the assumption that their national identity can influence significantly the evaluation of identity specificities are presented and analyzed, concerning more or less visible aspects of family life, like welfare status, relations between spouses, respect to the elder, family harmony, number of children, connections with relatives, etc.

  2. Unstable periodic orbits and chaotic economic growth

    International Nuclear Information System (INIS)

    Ishiyama, K.; Saiki, Y.


    We numerically find many unstable periodic solutions embedded in a chaotic attractor in a macroeconomic growth cycle model of two countries with different fiscal policies, and we focus on a special type of the unstable periodic solutions. It is confirmed that chaotic behavior represented by the model is qualitatively and quantitatively related to the unstable periodic solutions. We point out that the structure of a chaotic solution is dissolved into a class of finite unstable periodic solutions picked out among a large number of periodic solutions. In this context it is essential for the unstable periodic solutions to be embedded in the chaotic attractor

  3. Solitons supported by localized nonlinearities in periodic media

    International Nuclear Information System (INIS)

    Dror, Nir; Malomed, Boris A.


    Nonlinear periodic systems, such as photonic crystals and Bose-Einstein condensates (BEC's) loaded into optical lattices, are often described by the nonlinear Schroedinger or Gross-Pitaevskii equation with a sinusoidal potential. Here, we consider a model based on such a periodic potential, with the nonlinearity (attractive or repulsive) concentrated either at a single point or at a symmetric set of two points, which are represented, respectively, by a single δ function or a combination of two δ functions. With the attractive or repulsive sign of the nonlinearity, this model gives rise to ordinary solitons or gap solitons (GS's), which reside, respectively, in the semi-infinite or finite gaps of the system's linear spectrum, being pinned to the δ functions. Physical realizations of these systems are possible in optics and BEC's, using diverse variants of the nonlinearity management. First, we demonstrate that the single δ function multiplying the nonlinear term supports families of stableregular solitons in the self-attractive case, while a family of solitons supported by the attractive δ function in the absence of the periodic potential is completely unstable. In addition, we show that the δ function can support stable GS's in the first finite band gap in both the self-attractive and repulsive models. The stability analysis for the GS's in the second finite band gap is reported too, for both signs of the nonlinearity. Alongside the numerical analysis, analytical approximations are developed for the solitons in the semi-infinite and first two finite gaps, with the single δ function positioned at a minimum or maximum of the periodic potential. In the model with the symmetric set of two δ functions, we study the effect of the spontaneous symmetry breaking of the pinned solitons. Two configurations are considered, with the δ functions set symmetrically with respect to the minimum or maximum of the underlying potential.

  4. India's misconceived family plan. (United States)

    Jacobson, J L


    India's goal of reducing the national birth rate by 50% by the year 2000 is destined to failure in the absence of attention to poverty, social inequality, and women's subordination--the factors that serve to perpetuate high fertility. There is a need to shift the emphasis of the population control effort from the obligation of individual women to curtail childbearing to the provision of the resources required for poor women to meet their basic needs. Female children are less likely to be educated or taken for medical care than their male counterparts and receive a lower proportion of the family's food supply. This discrimination stems, in large part, from parents' view that daughters will not be able to remunerate their families in later life for such investments. The myth of female nonproductivity that leads to the biased allocation of family resources overlooks the contribution of adult women's unpaid domestic labor and household production. Although government statistics state that women comprise 46% of India's agricultural labor force (and up to 90% of rural women participate in this sector on some basis), women have been excluded systematically from agricultural development schemes such as irrigation projects, credit, and mechanization. In the field of family planning, the Government's virtually exclusive focus on sterilization has excluded younger women who are not ready to terminate childbearing but would like methods such as condoms, diaphragms, IUDs, and oral contraceptives to space births. More general maternal-child health services are out of reach of the majority of poor rural women due to long distances that must be travelled to clinics India's birth rate could be reduced by 25% by 2000 just by filling the demand for quality voluntary family planning services. Without a sustained political commitment to improve the status of women in India, however, such gains will not be sustainable.

  5. Maternity and family leave policies in rural family practices. (United States)

    Mainguy, S; Crouse, B J


    To help recruit and retain physicians, especially women, rural family practice groups need to establish policies regarding maternity and other family leaves. Also important are policies regarding paternity leave, adoptive leave, and leave to care for elderly parents. We surveyed members of the American Academy of Family Physicians in rural practice in 1995 to assess the prevalence of leave policies, the degree to which physicians are taking family leave, and the characteristics of ideal policies. Currently, both men and women physicians are taking family leaves of absence, which indicates a need for leave policies. Furthermore, a lack of family leave policies may deter women from entering rural practice.

  8. Depression in pregnancy and postpartum period. (United States)

    Sood, Mamta; Sood, A K


    This prospective study was carried out in a service hospital, with the aim to study the prevalence and incidence of depression in pregnancy and postpartum period. Eighty Four consecutive patients attending the antenatal outpatient in the Obstetrics & Gynaecology department in their last trimester of pregnancy were recruited for the study. They were assessed on Beck Depression Inventory thrice viz. during third trimester of pregnancy, within 3 days of delivery (early postpartum period) & within 4-8 weeks of delivery (late postpartum period).The prevalence of depression was 8.3%, 20% and 12.8% respectively at three ratings. The incidence was 16% and 10% in the early & late postpartum period respectively. Further analysis revealed that depression in pregnancy correlated significantly with depression in early postpartum period, but not with late postpartum period. Depression in early postpartum period correlated with depression in late postpartum period.These findings have implications for early detection and care of women at risk for developing depression.

  9. Periodic solutions of nonlinear vibrating beams

    Directory of Open Access Journals (Sweden)

    J. Berkovits


    Full Text Available The aim of this paper is to prove new existence and multiplicity results for periodic semilinear beam equation with a nonlinear time-independent perturbation in case the period is not prescribed. Since the spectrum of the linear part varies with the period, the solvability of the equation depends crucially on the period which can be chosen as a free parameter. Since the period of the external forcing is generally unknown a priori, we consider the following natural problem. For a given time-independent nonlinearity, find periods T for which the equation is solvable for any T-periodic forcing. We will also deal with the existence of multiple solutions when the nonlinearity interacts with the spectrum of the linear part. We show that under certain conditions multiple solutions do exist for any small forcing term with suitable period T. The results are obtained via generalized Leray-Schauder degree and reductions to invariant subspaces.

  10. Hungary: Secular fertility decline with distinct period fluctuations

    Directory of Open Access Journals (Sweden)

    Ferenc Kamarás


    Full Text Available In this study, we demonstrate from different angles that Hungarian fertility basically decreased between 1965 and 2005, but also clearly fluctuated, and showed different patterns in the different periods within this epoch. As a result, the clear communist-era family pattern of "early marriage and childbearing with two children" was replaced, but new family model(s have not yet fully emerged. We could show that profound changes in partnership behaviour -divorce and cohabitation- started before the change of the political regime, but also that changes in partnership relations accelerated after 1990, and that partnerships have become more fragile. In addition, Western-style values of "empty individualism" and consumerism were clearly present under socialism, but their motivating force was tamed by the communist system, in which population policy played a significant role. Of these institutional changes, we ascribe the greatest importance to the expansion in the educational system and the changes in the labour market. We show that, following the changes in the economic system, the conflict between family and work intensified. The synchronic consideration of values, labour market relations, economic development, and population policy; and the relationship of these factors to fertility and nuptiality trends, enabled us to formulate a developmental scheme of four phases concerning the evolution of fertility since 1965.

  11. Generating families in the restricted three-body problem

    CERN Document Server

    Hénon, Michel

    The classical restricted three-body problem is of fundamental importance because of its applications in astronomy and space navigation, and also as a simple model of a non-integrable Hamiltonian dynamical system. A central role is played by periodic orbits, of which many have been computed numerically. This is the second volume of an attempt to explain and organize the material through a systematic study of generating families, the limits of families of periodic orbits when the mass ratio of the two main bodies becomes vanishingly small. We use quantitative analysis in the vicinity of bifurcations of types 1 and 2. In most cases the junctions between branches can now be determined. A first-order approximation of families of periodic orbits in the vicinity of a bifurcation is also obtained. This book is intended for scientists and students interested in the restricted problem, in its applications to astronomy and space research, and in the theory of dynamical systems.

  12. Sustainability Reporting in Family Firms: A Panel Data Analysis

    Directory of Open Access Journals (Sweden)

    Giovanna Gavana


    Full Text Available We analyze the largely unexplored differences in sustainability reporting within family businesses using a sample of 230 non-financial Italian listed firms for the period 2004–2013. Drawing on legitimacy theory and stakeholder theory, integrated with the socio-emotional wealth (SEW approach, we study how family control, influence and identification shape a firm’s attitude towards disclosing its social and environmental behavior. Our results suggest that family firms are more sensitive to media exposure than their non-family counterparts and that family control enhances sustainability disclosure when it is associated to a family’s direct influence on the business, by the founder’s presence on the board or by having a family CEO. In cases of indirect influence, without family involvement on the board, the level of family ownership is negatively related to sustainability reporting. On the other hand, a formal identification of the family with the firm by business name does not significantly affect social disclosure.

  13. Family Impacts on Self-Esteem in Chinese College Freshmen

    Directory of Open Access Journals (Sweden)

    Jingyu Shi


    Full Text Available This study examined the impact of family function and family-related factors, such as being an only child, grandparenting, income, and family relationship on the self-esteem in college students who are in the transitional period from late adolescence to emerging adulthood. The participants were 2001 Chinese college freshmen with the age from 16 to 20 years. Data were collected by using the family assessment device (FAD, the Rosenberg Self-esteem Scale, and self-report of family information. Comparison analysis indicated that the students from one child families, harmonious families, from families with higher income, or raised by their parents without the experience of grandparenting are more likely to show high self-esteem than their counterparts. Moreover, a multiple regression showed that dimensions of FAD such as role, communication, behavioral control, and problem solving predicted level of self-esteem of the college students, ranging from 13.2 to 17.9% variance. The results of this study showed that the self-esteem of the college freshmen is highly correlated with their family’s performance. Therefore, the program focusing on improving family functioning is needed, in order to enhance the self-esteem of the young people and hence contribute to promoting the mental health of them.

    The initial composition of current models of cometary nuclei is only based on two forms of ice: crystalline ice for long-period comets and amorphous ice for short-period comets. A third form of ice, i.e., clathrate hydrate, could exist within the short-period cometary nuclei, but the area of formation of this crystalline structure in these objects has never been studied. Here, we show that the thermodynamic conditions in the interior of short-period comets allow the existence of clathrate hydrates in Halley-type comets. We show that their existence is viable in the Jupiter family comets only when the equilibrium pressure of CO clathrate hydrate is at least 1 order of magnitude lower than the usually assumed theoretical value. We calculate that the amount of volatiles that could be trapped in the clathrate hydrate layer may be orders of magnitude greater than the daily amount of gas released at the surface of the nucleus at perihelion. The formation and the destruction of the clathrate hydrate cages could then explain the diversity of composition of volatiles observed in comets, as well as some pre-perihelion outbursts. We finally show that the potential clathrate hydrate layer in comet 67P/Churyumov-Gerasimenko would, unfortunately, be deep inside the nucleus, out of reach of the Rosetta lander. However, such a clathrate hydrate layer would show up by the gas composition of the coma.

  16. [Cryopyrine-associated periodic syndrome: CAPS seen from adulthood]. (United States)

    Koné-Paut, I


    Cryopyrin-associated periodic syndrome is a rare hereditary periodic fever syndrome for which, the genetic mechanism, mutation in the NLRP3 gene, has allowed to gather 3 clinical phenotypes (familial cold urticaria [FCAS], Muckle-Wells syndrome [MWS], and chronic infantile neurological cutaneous and articular syndrome [CINCA]) initially described independently, and to discover the NLRP3 inflammasome, a key receptor of the innate immunity, which regulates the interleukine-1β secretion into the mononuclear cells. The clinical manifestation of CAPS : urticaria-like skin rash, eyes redness, myalgia and sensory deafness are not specific, if considered separately, and that often leads to a wandering diagnosis through a complex medical journey including various specialists. The diagnostic delay is deleterious to patients compromising their quality of life and exposing them to neurosensory complications and renal failure by secondary amyloidosis. The paediatric onset of disease, the family history, the trigger of symptoms by the cold, and the recognition of the skin rash as neutrophilic are important clues before diagnostic confirmation by genetic testing. Interleukine-1 blockade is the only effective treatment of CAPS symptoms which often may stabilize (rarely regression) the sensory involvement and in some cases may allow the regression of secondary amyloidosis.

  5. The child and the family: interdependence in developmental pathways

    Directory of Open Access Journals (Sweden)

    Kurt Kreppner

    Full Text Available This contribution focuses on the family as the major context for children's development, it includes concepts of the family as an institution for the transmission of meaning on the one hand, and it formulates implications for new theoretical and methodological approaches in the field of family research on the other. The idea of transmission of a society's meaning system via the family is discussed under the perspective that the socialization of children in the family provides a continuous basis for the aggregation of common knowledge over generations. The systems approach is taken as a promising model for dealing with the complex continuity and change issues during development. Data will be presented from two longitudinal studies, in which parent-child communication behavior was analyzed over time during two critical developmental periods, during the first two years after the birth of a second child and during the transition from childhood to adolescence.

  9. Putting theory to the test: Examining family context, caregiver motivation, and conflict in the Family Check-Up model (United States)

    Fosco, Gregory M.; Van Ryzin, Mark; Stormshak, Elizabeth A.; Dishion, Thomas J.


    This study examined contextual factors (caregiver depression, family resources, ethnicity, and initial levels of youth problem behavior) related to the effectiveness of the Family Check-Up (FCU) and evaluated family processes as a mediator of FCU intervention response and adolescent antisocial behavior. We followed a sample of 180 ethnically diverse youths of families who engaged in the FCU intervention. Family data were collected as part of the FCU assessment, and youth data were collected over 4 years, from sixth through ninth grade. Findings indicated that caregiver depression and minority status predicted greater caregiver motivation to change. In turn, caregiver motivation was the only direct predictor of FCU intervention response during a 1-year period. Growth in family conflict from sixth through eighth grade mediated the link between FCU response and ninth-grade antisocial behavior. This study explicitly tested core aspects of the FCU intervention model and demonstrated that caregiver motivation is a central factor that underlies family response to the FCU. The study also provided support for continued examination of family process mechanisms that account for enduring effects of the FCU and other family-centered interventions. PMID:24438894

    Full Text Available Familial Mediterranean Fever is an autosomal recessive inherited disease with a course of autoinflammation, which is characterized by the episodes of fever and serositis. It affects the populations from Mediterranean basin. Genetic mutation of the disease is on MEFV gene located on short arm of Chromosome 16. The disease is diagnosed based on clinical evaluation. Amyloidosis is the most important complication. The only agent that decreases the development of amyloidosis and the frequency and severity of the episodes is colchicine, which has been used for about 40 years. In this review, we aimed to discuss especially the most recent advances about Familial Mediterranean Fever which is commonly seen in our population.

  16. Family resources study: part 1: family resources, family function and caregiver strain in childhood cancer. (United States)

    Panganiban-Corales, Avegeille T; Medina, Manuel F


    Severe illness can disrupt family life, cause family dysfunction, strain resources, and cause caregiver burden. The family's ability to cope with crises depends on their resources. This study sought to assess families of children with cancer in terms of family function-dysfunction, family caregiver strain and the adequacy of family resources using a new family resources assessment instrument. This is a cross-sectional study involving 90 Filipino family caregivers of children undergoing cancer treatment. This used a self-administered questionnaire composed of a new 12-item family resources questionnaire (SCREEM-RES) based on the SCREEM method of analysis, Family APGAR to assess family function-dysfunction; and Modified Caregiver Strain Index to assess strain in caring for the patient. More than half of families were either moderately or severely dysfunctional. Close to half of caregivers were either predisposed to strain or experienced severe strain, majority disclosed that their families have inadequate economic resources; many also report inaccessibility to medical help in the community and insufficient educational resources to understand and care for their patients. Resources most often reported as adequate were: family's faith and religion; help from within the family and from health providers. SCREEM-RES showed to be reliable with Cronbach's alpha of 0.80. There is good inter-item correlation between items in each domain: 0.24-0.70. Internal consistency reliability for each domain was also good: 0.40-0.92. Using 2-point scoring system, Cronbach's alpha were slightly lower: full scale (0.70) and for each domain 0.26-.82. Results showed evidence of association between family resources and family function based on the family APGAR but none between family resources and caregiver strain and between family function and caregiver strain.

    Nilles, Hans Peter


    Discrete (family) symmetries might play an important role in models of elementary particle physics. We discuss the origin of such symmetries in the framework of consistent ultraviolet completions of the standard model in field and string theory. The symmetries can arise due to special geometrical properties of extra compact dimensions and the localization of fields in this geometrical landscape. We also comment on anomaly constraints for discrete symmetries.

    There is little information about familial aggregation of insomnia; however, this type of information is important to (1) improve our understanding of insomnia risk factors and (2) to design more effective treatment and prevention programs. This study aimed to investigate evidence of familial aggregation of insomnia among first-degree relatives of probands with and without insomnia. Cases (n = 134) and controls (n = 145) enrolled in a larger epidemiological study were solicited to invite their first-degree relatives and spouses to complete a standardized sleep/insomnia survey. In total, 371 first-degree relatives (Mage = 51.9 years, SD = 18.0; 34.3% male) and 138 spouses (Mage = 55.5 years, SD = 12.2; 68.1% male) completed the survey assessing the nature, severity, and frequency of sleep disturbances. The dependent variable was insomnia in first-degree relatives and spouses. Familial aggregation was claimed if the risk of insomnia was significantly higher in the exposed (relatives of cases) compared to the unexposed cohort (relatives of controls). The risk of insomnia was also compared between spouses in the exposed (spouses of cases) and unexposed cohort (spouses of controls). The risk of insomnia in exposed and unexposed biological relatives was 18.6% and 10.4%, respectively, yielding a relative risk (RR) of 1.80 (p = .04) after controlling for age and sex. The risk of insomnia in exposed and unexposed spouses was 9.1% and 4.2%, respectively; however, corresponding RR of 2.13 (p = .28) did not differ significantly. Results demonstrate evidence of strong familial aggregation of insomnia. Additional research is warranted to further clarify and disentangle the relative contribution of genetic and environmental factors in insomnia. © Sleep Research Society 2016.

  9. The netrin protein family. (United States)

    Rajasekharan, Sathyanath; Kennedy, Timothy E


    The name netrin is derived from the Sanskrit Netr, meaning 'guide'. Netrins are a family of extracellular proteins that direct cell and axon migration during embryogenesis. Three secreted netrins (netrins 1, 3 and 4), and two glycosylphosphatidylinositol (GPI)-anchored membrane proteins, netrins G1 and G2, have been identified in mammals. The secreted netrins are bifunctional, acting as attractants for some cell types and repellents for others. Receptors for the secreted netrins include the Deleted in Colorectal Cancer (DCC) family, the Down's syndrome cell adhesion molecule (DSCAM), and the UNC-5 homolog family: Unc5A, B, C and D in mammals. Netrin Gs do not appear to interact with these receptors, but regulate synaptic interactions between neurons by binding to the transmembrane netrin G ligands NGL1 and 2. The chemotropic function of secreted netrins has been best characterized with regard to axon guidance during the development of the nervous system. Extending axons are tipped by a flattened, membranous structure called the growth cone. Multiple extracellular guidance cues direct axonal growth cones to their ultimate targets where synapses form. Such cues can be locally derived (short-range), or can be secreted diffusible cues that allow target cells to signal axons from a distance (long-range). The secreted netrins function as short-range and long-range guidance cues in different circumstances. In addition to directing cell migration, functional roles for netrins have been identified in the regulation of cell adhesion, the maturation of cell morphology, cell survival and tumorigenesis.

  11. Undefined familial colorectal cancer. (United States)

    Zambirinis, Constantinos Pantelis; Theodoropoulos, George; Gazouli, Maria


    Colorectal cancer (CRC), one of the most common cancers of the world, is actually a spectrum of several subtypes, with different molecular profiles, clinico-pathological characteristics and possibly separate pathways of progression. It is estimated that in approximately 25%-35% of cases, a familial component exists, so they are classified as familial CRC (fCRC). However the known hereditary CRC syndromes justify only up to 5%. The rest are attributed to some inherited genetic predisposition passed to offspring through low-penetrance genes, which in the proper environmental setting can bring on tumorigenesis. Furthermore, part of the familial clustering may be attributed to chance. Because of the complexity regarding the etiology of CRC, the clinician is sometimes faced with obscure patient data, and cannot be sure if they are dealing with fCRC or sporadic CRC. The elucidation of what is going on with the as yet "undefined" portion of CRC will aid not only in the diagnosis, classification and treatment of CRC, but more importantly in the proper adjustment of the screening guidelines and in genetic counselling of patients.

  12. [Familial Wolfram syndrome]. (United States)

    Bessahraoui, M; Paquis, V; Rouzier, C; Bouziane-Nedjadi, K; Naceur, M; Niar, S; Zennaki, A; Boudraa, G; Touhami, M


    Wolfram syndrome (WS) is a rare autosomal recessive progressive neurodegenerative disorder, and it is mainly characterized by the presence of diabetes mellitus and optic atrophy. Other symptoms such as diabetes insipidus, deafness, and psychiatric disorders are less frequent. The WFS1 gene, responsible for the disease and encoding for a transmembrane protein called wolframin, was localized in 1998 on chromosome 4p16. In this report, we present a familial observation of Wolfram syndrome (parents and three children). The propositus was a 6-year-old girl with diabetes mellitus and progressive visual loss. Her family history showed a brother with diabetes mellitus, optic atrophy, and deafness since childhood and a sister with diabetes mellitus, optic atrophy, and bilateral hydronephrosis. Thus, association of these familial and personal symptoms is highly suggestive of Wolfram syndrome. The diagnosis was confirmed by molecular analysis (biology), which showed the presence of WFS1 homozygous mutations c.1113G>A (p.Trp371*) in the three siblings and a heterozygote mutation in the parents. Our observation has demonstrated that pediatricians should be aware of the possibility of Wolfram syndrome when diagnosing optic atrophy in diabetic children. Copyright © 2014 Elsevier Masson SAS.

  13. The effects of organizational and community embeddedness on work-to-family and family-to-work conflict. (United States)

    Ng, Thomas W H; Feldman, Daniel C


    The present study offers competing hypotheses regarding the relationships of changes in organizational and community embeddedness with changes in work-to-family and family-to-work conflict. Data were collected from 250 U.S. and 165 Chinese managers and professionals, all of whom were married, at 3 points in time over a 10-month period. Results suggest that increases in perceptions of organizational and community embeddedness are associated with increases in work-to-family conflict and family-to-work conflict over time. Further, we found that these effects were even stronger for employees with highly individualistic values. Thus, although much of the previous research has focused on the positive effects of employee embeddedness for individuals' work lives, the present study provides some evidence of the potentially negative effects of employee embeddedness for individuals' family lives.

  15. Family support group in psychosocial rehabilitation (United States)

    Ponnuchamy, L.; Mathew, Baijumon K.; Mathew, Sheeba; Udayakumar, G.S.; Kalyanasundaram, S.; Ramprasad, Dharitri


    Background: Support groups for families of persons with mental illness are emerging as significant components in psychosocial rehabilitation programmes. Aim: To ascertain the expectations of family members who attend family support group meetings and to find out the efficacy of such programmes. Methods: The data were collected from support group members using a semi-structured interview schedule. The study sample (n=20) was drawn from family members who attended the support group meetings regularly for a minimum period of 6 months. Data analysis was done using percentile. Results: Analysis of the data revealed that members attending the support group meetings expected to get more information about the illness, develop skills to cope with problems at home and learn skills to deal with the ill person. An important finding of the study was that the members developed a ‘feeling of togetherness’ as a result of being a member of a group with common aims. Conclusion: Participation in a support group meeting positively affects key variables in the participant's adaptation to mental illness in a relative. PMID:20814460

  16. Asteroid families in the Cybele and Hungaria groups (United States)

    Vinogradova, T.; Shor, V.


    Asteroid families are fragments of some disrupted parent bodies. Planetary perturbations force the primarily close orbits to evolve. One of the main features of the orbit evolution is the long-period variation of the osculating elements, such as the inclination and eccentricity. Proper elements are computed by elimination of short- and long-period perturbations, and, practically, they do not change with time. Therefore, proper elements are important for family-identification procedures. The techniques of proper-element computation have improved over time. More and more accurate dynamical theories are developed. Contrastingly, in this work, an empirical method is proposed for proper-element calculations. The long-term variations of osculating elements manifest themselves very clearly in the distributions of pairs: inclination and longitude of ascending node; eccentricity and longitude of perihelion in the corresponding planes. Both of these dependencies have a nearly sinusoidal form for most asteroid orbits with regular motion of node and perihelion. If these angular parameters librate, then the sinusoids transform to some closed curve. Hence, it is possible to obtain forced elements, as parameters of curves specified above. The proper elements can be calculated by an elimination of the forced ones. The method allows to obtain the proper elements in any region, if there is a sufficient number of asteroids. This fact and the simplicity of the calculations are advantages of the empirical method. The derived proper elements include the short-period perturbations, but their accuracy is sufficient to search for asteroid families. The special techniques have been developed for the identification of the families, but over a long time large discrepancies took place between the lists of families derived by different authors. As late as 1980, a list of 30 reliable families was formed. And now the list by D. Nesvorny includes about 80 robust families. To date, only two

  17. Handgun waiting periods reduce gun deaths. (United States)

    Luca, Michael; Malhotra, Deepak; Poliquin, Christopher


    Handgun waiting periods are laws that impose a delay between the initiation of a purchase and final acquisition of a firearm. We show that waiting periods, which create a "cooling off" period among buyers, significantly reduce the incidence of gun violence. We estimate the impact of waiting periods on gun deaths, exploiting all changes to state-level policies in the Unites States since 1970. We find that waiting periods reduce gun homicides by roughly 17%. We provide further support for the causal impact of waiting periods on homicides by exploiting a natural experiment resulting from a federal law in 1994 that imposed a temporary waiting period on a subset of states.

  18. A highly specific test for periodicity

    Ansmann, Gerrit, E-mail: [Department of Epileptology, University of Bonn, Sigmund-Freud-Straße 25, 53105 Bonn (Germany); Helmholtz Institute for Radiation and Nuclear Physics, University of Bonn, Nussallee 14–16, 53115 Bonn (Germany); Interdisciplinary Center for Complex Systems, University of Bonn, Brühler Straße 7, 53175 Bonn (Germany)


    We present a method that allows to distinguish between nearly periodic and strictly periodic time series. To this purpose, we employ a conservative criterion for periodicity, namely, that the time series can be interpolated by a periodic function whose local extrema are also present in the time series. Our method is intended for the analysis of time series generated by deterministic time-continuous dynamical systems, where it can help telling periodic dynamics from chaotic or transient ones. We empirically investigate our method's performance and compare it to an approach based on marker events (or Poincaré sections). We demonstrate that our method is capable of detecting small deviations from periodicity and outperforms the marker-event-based approach in typical situations. Our method requires no adjustment of parameters to the individual time series, yields the period length with a precision that exceeds the sampling rate, and its runtime grows asymptotically linear with the length of the time series.
