First record of Potamogeton×salicifolius for Italy, with isozyme evidence for plants collected in Italy and Sweden

Abstract Potamogeton×salicifolius, a hybrid between P. lucens and P. perfoliatus, is identified as a new taxon for Italy. This is the first record of this hybrid from southern Europe. The Italian sample was studied in cultivation and compared with a living specimen of P.×salicifolius from Sweden, where the hybrid is rather widespread. In addition to morphological features, the most compelling evidence for the hybrid origin of these plants came from the isozyme analysis. The additive “hybrid” banding patterns of the five enzyme systems studied indicate inheritance from P. lucens and P. perfoliatus. The distribution of this hybrid in Europe coincides with the areas most severely affected by the Late Pleistocene glaciation. The relationships between environmental conditions, history of the habitat and rise of hybrids are discussed.
Menopause in HIV Infected Women: A Comprehensive Approach to Physical and Psychological Health

Objective: The number of HIV-infected women experiencing menopause is rapidly increasing. The aim of this study was to compare the physical and psychological health profile of menopausal women with and without HIV. Methods: Case-control study, assessing clinical manifestations of menopause in HIV infected cases and in uninfected controls. Determinants of physical (subclinical cardiovascular diseases, prevalence of diabetes mellitus, chronic kidney disease, hypothyroidism and risk of osteoporotic fractures) and psychological health (depression, quality of life in menopause and sexual dysfunction) were evaluated. The prevalence of poly-pathology (Pp) defined as the concurrent presence of 2 or more diseases was also assessed. Results: 29 (47.5%) HIV-infected and 32 (52.5%) HIV-uninfected postmenopausal women infection were enrolled. On average, menopause occurred 3 years earlier in HIV-infected than in uninfected women (p= .01). In spite of a trend toward a greater prevalence of Pp (p=.22), the only physical indicators differing between cases and controls were a greater risk profile for osteoporotic fracture (p<0.001) and a significantly increased arterial stiffness (p=.007). In addition, cases exhibited a poorer psychological health profile with regard to depression (p=.005), sexual dysfunction (p=.02) and physical menopausal symptoms (p=.05). Conclusion: In spite of a relatively similar physical health profile, menopause in HIV infected women is characterized by a poorer psychological profile compared to HIV uninfected women.
THE RELATIONSHIP BETWEEN TEAM IDENTITY AND SPECTATOR SATISFACTION IN TRACTORSAZI TABRIZ FOOTBALL TEAM

The aim of the present study was to investigate the relationship between team identity and spectator satisfaction in Tractorsazi Tabriz football team. The research method is of a descriptive and correlation. The statistical population consisted of 39,000 Tractorsazi Tabriz fans above 21 years of age who gathered in the Yadegar Imam (RA) Stadium to watch a football game held in the 2013-14 Asian Championship League series. A sample of 225 spectators was selected randomly according to Morgan's table for determining sample size. For collecting data, two questionnaires of, Trail & James team identity and Oliver’s satisfaction inventory were used. After data collection, data were analyzed using Pearson's correlation coefficient and one-sample T-test. The result showed that status of team identity according to Spectators of Tractorsazi football team has significantly an above the average level. Also the rate of satisfaction of spectator has significantly higher an above the average (t=16.40, sig=0.001). Analyzing correlation between variables showed that there is a significant positive relationship between team identity and spectator satisfaction (r= 0.515, p <0.001).
IPO Stocks Performance Imperfection: A Review of Models and Empirical Works

Performance of IPO stocks is determined by the returns on a firm’s IPOs and other subsequent issues. Returns are derived from the price swings (volatility) as compared to the offer price so that a favourable swing indicates favourable returns and vice-versa. In the light of this, we review models and empirical works that try to explain these swings and their consequence on the IPOs performance to hypothesize that IPO stocks performance swing (return volatility) is inevitable as far as a real efficient market cannot exist except in a world of utopia. Evidences from the previous studies show that one reason or the other must be achieved or committed to get the IPO stocks marketed at the instance of the issue which subsequently keep influencing the same stocks even in the secondary market over a very long period of time even though at a minimum volatile rate but not completely eliminated. This is what we regard as stocks performance imperfection.
EFFECT OF CYCOCEL AND DAMINOZIDE ON VEGETATIVE GROWTH, FLOWERING AND THE CONTENT OF ESSENCE OF POT MARIGOLD (CALENDULA OFFICINALIS)

Pot marigold (Calendula officinalis L.) is a medicinal and ornamental plant. The effect of different concentrations of chlormequat (cycocel), and daminozide, two plant growth retardant, on plant height, flowering, the content of essence and some other traits in pot marigold (Calendula officinalis) was assessed. Plant growth retardants are commonly applied to limit stem elongation and produce a more compact plant. The experiment was done as a factorial in randomized completely blocks design (R.C.B.D.) with 16 treatments and 3 replications in Rasht. Cycocel at 4 concentrations (0, 500, 1000 and 1500 mg/L) and daminozide at 4 concentrations (0, 1500, 3000 and 4500 mg/L) were used. Investigated characteristics were plant height, leaf number, flower number, flowering time, fresh weight, dry matter, the content of essence and carotenoid in flowers. Based on analysis of variance (ANOVA), the effect of different treatments and their interaction on most traits was significant at 0.05 level of probability. The minimum height (24 cm/plant) in treatment of 500 mg/L cycocel + 3000 mg/L daminozide, the largest number of flowers (4.66 flowers/plant) in treatment of 1000 mg/L cycocel + 4500 mg/L daminozide and most essence content (0.154 mg/100 g) in treatment of 4500 mg/L daminozide without cycocel were obtained.
Professional Knowledge of (Prospective) Mathematics Teachers - Its Structure and Development

Recent research on the professional knowledge of mathematics teachers, which hasbeen carried out in the last decade, is in the focus of this paper. Building on theinternational IEA Teacher Education and Development Study – Learning to TeachMathematics (TEDS-M), this paper describes a more situated way of evaluating theprofessional knowledge of teachers. The theoretical framework of the follow-upstudy of TEDS-M takes up the novice-expert framework and analyses via videobasedassessment instruments the structure and development of the professionalknowledge of mathematics teachers. More recent concepts on noticing andinterpreting classroom situations and students’ activities are also incorporated intothe analysis. Connecting the results of the study TEDS-FU with the study TEDS-Mgives insight into the development of the professional knowledge of mathematicsteachers.
A behavioral study of angora goats on west Texas range.

Behavior of four Angora goats was studied in sixteen observation periods for four seasons on a west Texas range. The goats consistently fed during two definite daylight feeding periods: (a) early morning, and (b) late afternoon to dusk. Bedding generally occurred whenever darkness became evident and little or no feeding activity was observed between that time and daybreak. The four goats differed somewhat in their behavioral activities, but were remarkably similar in their vegetation preference. Seasonal difference seemed to have an imnortant effect unon both vegetative preference and behavioral I A
Differences in heritability of craniofacial skeletal and dental characteristics between hypo- and hyper-divergent patterns using Falconer's method and principal component analysis.

OBJECTIVES: To investigate the difference in heritability of craniofacial skeletal and dental characteristics between hypodivergent and hyperdivergent patterns. MATERIALS AND METHODS: 53 Korean adult monozygotic (MZ) and dizygotic (DZ) twins and their siblings were divided into a hypodivergent group (Group 1, SN-MP < 35°, 17 MZ pairs; 11 DZ and sibling [DS] pairs of the same gender) and hyper-divergent group (Group 2, SN-MP > 35°, 16 MZ pairs; 9 DS pairs of the same gender). A total of 56 cephalometric variables were measured using lateral cephalographs. Craniofacial structures were divided into anteroposterior, vertical, dental, mandible, and cranial base characteristics. Falconer's method was used to calculate heritability (h2 > 0.8, high). After principal component analysis (PCA), the mean h 2 value of each component was calculated. RESULTS: Group 1 exhibited high heritability values in shape and position of the mandible, vertical angular/ratio variables, cranial base shape, and maxillary incisor inclination. Group 2 showed high heritability values in anteroposterior position of the maxilla, intermaxillary relationship, vertical angular variables, cranial base length, and mandibular incisor inclination. Occlusal plane inclination showed high heritability in both groups. Although vertical structure presented a high overall mean h 2 value in Group 1, there were no structures that exhibited a high overall mean h 2 value in Group 2. PCA derived 10 components with 91.2% and 92.7% of cumulative explanation in Groups 1 and 2, respectively. CONCLUSIONS: It is necessary to estimate or predict growth according to vertical pattern for providing differential diagnosis and orthodontic/orthopedic treatment planning.
Improving Primary Students' Mathematical Literacy through Problem Based Learning and Direct Instruction.

This research was done on primary school students who are able to understand mathematical concepts, but unable to apply them in solving real life problems. Therefore, this study aims to improve primary school students' mathematical literacy through problem-based learning and direct instruction. In addition, the research was conducted to determine whether there are differences in the increase in literacy mathematical among students who received problem-based learning and direct instruction in primary schools located in urban areas, transition, and villages, as well as whether there is an interaction effect between the model of learning by location category of the school toward mathematical literacy skills of primary school students. The study was conducted in the academic year 2015 to 2016 in the fifth grade public primary schools in Bandung with three categories of school location (rural, city and county transition). During the research, one experimental group was treated by problem based learning, while the second experimental group was treated by direct instruction. The research approach used was a quantitative approach with quasi experimental method nonequivalent groups design pretest-posttests. The results showed that: there was a significant difference between the increase in mathematical literacy of students who received a model of problem-based learning (PBL) and direct instruction (DI) model; PBL model was more effective in improving students' mathematical literacy model than the DI; There were no significant differences regarding an increase in students' mathematical literacy by category location of the school; there is no interaction effect between the model of learning by school location factors to the increase in students' mathematical literacy. Key words: Mathematical literacy, problem based learning, direct instruction, mathematics education, primary school.
An $M_{q}()$-functional calculus for power-bounded operators on certain UMD spaces

For 1 q 1 (the range of q depending on X). This multiplier result expands the vector-valued Marcinkiewicz Multiplier Theorem in the directionq > 1. More- over, when taken in conjunction with vector-valued transference, this Mq(T)-multiplier result shows that if X2I, and U is an invertible power-bounded operator on X, then U has an Mq(T)-functional calculus for an appropriate range of values of q > 1. The class I includes, in particular, all closed subspaces of the von Neumann{Schatten p-classesCp (1 < p <1), as well as all closed subspaces of any UMD lattice of functions on a -nite measure space. The Mq(T)-functional calculus result forI, when specialized to the setting of closed subspaces of L p ( ) ( an arbitrary measure, 1 < p <1), recovers a previous result of the authors.
Freedom of Speech, the Market for Ideas and the Issue of Ownership and Concentration in the Newspaper Sector

The newspaper sector has a key role in a democratic state. The freedom to express ideas as well as pluralism in the supply of ideas, are fundamental to a democratic society. In many countries the constitution prevents government from regulating the market for ideas since Antitrust laws and Competition Acts cannot be used to the same extent as in other markets. This paper will look more closely at the impact of ownership and concentration on performance in the Swedish newspaper sector and discuss if there is a clash between freedom of ideas and efficient performance in the media sector. Sweden offers an interesting case for two reasons. Firstly, there are different types of ownership categories and firm types that play important roles within the media sector. Secondly, the Swedish government has recently begun investigating whether the Competition Act can be applied to halt or slow down the concentration of media ownership. The purpose is to apply economic theory to the discussion of freedom of speech and ownership concentration, a discussion which is generally dominated by other disciplines.
Use of peripheral lymphocytes and support vector machine for survival prediction in breast cancer patients

Background: This study aimed to identify the influence of peripheral lymphocytes on prognosis and find prognostic markers for breast cancer patients. Methods: This study enrolled invasive breast cancer patients and they were followed-up for median 4-years over telephone. Distributions of disease-free survival (DFS) and overall survival (OS) between different levels of lymphocytes were estimated with the Kaplan-Meier (K-M) method. Support vector machine (SVM) methods were used to develop a prognostic classifier for breast cancer. Results: A total of 190 patients were enrolled. Patients with low level of cluster of differentiation (CD)3+ lymphocytes had worse DFS and OS (P Conclusions: Patients with low level of CD3+ lymphocytes could have a poorer survival and the SVM method could predict prognosis in breast cancer patients.
Monoamine Oxidase in the Regulation of Biopsychological Factors: A Literature Review of the Correlates of Time Perspective, Sensation-Seeking, Boredom Proneness, and Affect

This literature review will explore relationships between several psychological factors, such as affect, time perspective, and boredom, with levels of relevant neurotransmitters, namely dopamine and serotonin. For instance, the neurological processes involved in affect could also influence sensation-seeking through changes in cognition and boredom. Additionally, a more negative mood resulting from decreased dopamine levels could result in short-term shifts in one’s time perspective. Monoamine oxidase plays a role in the regulation of neurotransmitter levels in the brain. Large amounts of this enzyme result in reduced levels of dopamine and serotonin. Understanding such relationships has the potential to propel further research in biopsychology and influence clinical and counseling methods used for people with harmful sensation-seeking addictions and other related disorders. Abbreviations: ZTPI – Zimbardo’s Time Perspective Inventory; SSS – Sensation-Seeking Scale; Dis – Disinhibition; TAS – Thrill and Adventure Seeking; BPS – Boredoms Proneness Scale; 5-HT – 5 hydroxytryptamine; MAO – Monoamine Oxidase MONOAMINE OXIDASE ON BIOPSYCHOLOGICAL FACTORS 2 Monoamine Oxidase in the Regulation of Biopsychological Factors: A Literature Review of the Correlates of Time Perspective, Sensation-Seeking, Boredom Proneness, and Affect The purpose of this paper is to examine the literature regarding correlates of affect, time perspective, sensation-seeking, and boredom proneness in relation to the activity of specific neurotransmitters, including dopamine and serotonin, and the enzyme monoamine oxidase. For purposes of specificity, this review will discuss these topics in the context of the tendency to take part in impulsive, short-term, risk-taking behaviors (e.g., gambling, drunk driving, drug use, etc.), rather than in the context of a long-term, cognitive process. It will look at the effects of dopamine and serotonin in particular, as these seem to be prominent influences of behavior (Vondavich, 1990). Because there is a well-recognized difference in the level of these neurotransmitters between men and women (Zuckerman, Eysenck, & Eysenck, 1978), this review will briefly consider gender differences in each of the previously-mentioned areas of interest. It will also examine age differences in those same areas. These topics and their correlations will then be related to the common factor of the enzyme monoamine oxidase. The effects of this enzyme in contributing to the correlations of affect, time perspective, sensationseeking, and boredom will be discussed.
Simulation Study for the Energy Resolution Performances of Homogenous Calorimeters with Scintillator-Photodetector Combinations

The scintillating properties of active materials used in high energy and particle physics experiments play an important role regarding the performances of both calorimeters and experiments. Two scintillator materials, a scintillating glass and an inorganic crystals, were examined to be used for collider experiments showing good optical and scintillating properties. This paper discusses the simulated performances of two materials of interest assembled in a scintillator-photodetector combination. The computational study was carried out with Geant4 simulation program to determine energy resolutions of such calorimeter with different beam energies and calorimeter sizes.
Preisach images of a simple mechanical system

This work is an an early stage of a larger project aiming at answering the question whether or not the Preisach map is really fingerprinting magnetic materials. More precisely, we are interested whether Preisach model of magnetic hysteresis indeed contains any physics or is just a convenient modeling tool. To this extent we study a very simple mechanical system, thus fully tractable, subjected to the external force. Despite of its simplicity, our model captures all the fundamental features of real magnetic materials, namely their hysteretic behavior, coercivity, remanent magnetization and saturation at high fields. Both the overall shape of major hysteresis loop as well as First Order Reversal Curves (FORC's) are reproduced quite correctly; they are very similar to those observed in magnetic materials. The model essentially consists of a single, spring loaded, rigid and rotative bar with non-zero friction torque. The length of a projection of this bar onto the direction of an external force is identified with magnetization. The friction torque and the spring constant are the only freely adjustable parameters of our model. Here we investigate, and present, their influence on the inferred Preisach maps.
The role of convective overshooting clouds in tropical stratosphere–troposphere dynamical coupling

Abstract. This paper investigates the role of deep convection and overshooting convective clouds in stratosphere–troposphere dynamical coupling in the tropics during two large major stratospheric sudden warming events in January 2009 and January 2010. During both events, convective activity and precipitation increased in the equatorial Southern Hemisphere as a result of a strengthening of the Brewer–Dobson circulation induced by enhanced stratospheric planetary wave activity. Correlation coefficients between variables related to the convective activity and the vertical velocity were calculated to identify the processes connecting stratospheric variability to the troposphere. Convective overshooting clouds showed a direct relationship to lower stratospheric upwelling at around 70–50 hPa. As the tropospheric circulation change lags behind that of the stratosphere, outgoing longwave radiation shows almost no simultaneous correlation with the stratospheric upwelling. This result suggests that the stratospheric circulation change first penetrates into the troposphere through the modulation of deep convective activity.
Why female genital cutting persists

Female Genital Cutting (FGC) remains a pervasive practice in sub-Saharan Africa. Using cross-sectional data from 13 African countries, I contrast health consequences and cultural-economic considerations to explain its continuance. The novelty of this study lies in its representativeness of the population at large and across countries, which allows drawing general lessons about the mechanisms underlying FGC. I demonstrate that ethnic and religious identity foster this intentionally health-destructing practice; being cut increases marriage prospects by almost 40%. While general health impairments or decreased fertility are often used as arguments against FGC, I –in line with medical research– do not find evidence thereof; in fact, cut women have more children on average. Though, unsurprisingly they also have up to 25% increased odds of contracting a sexually transmitted infection. The findings question the health-focused anti-FGC campaigns as FGC-induced health impairments might be conceived as negligible compared to socio-cultural gains by those women concerned.

The Evaluation of a National Forest Harvest Scheduling System for Ireland – Two Case Studies

Abstract Coillte Teoranta (the Irish Forestry Board) harvested approximately 2.0 million m3 in 1994. By the year 2000 this annual harvest is projected to increase to approximately 2.8 million m3 and to 3.7 million m3 by the year 2011. To facilitate the management of these increased timber flows more efficiently and effectively, the Harvest Scheduling System (HSS) was developed. In order to evaluate the HSS’s solutions, five case studies were carried out, two of which are presented in this paper. Initially, the HSS model was solved without any management constraints, resulting in a theoretical maximum net present value (NPV) (case study 1). Subsequently, the effect of imposing national and regional level volume fluctuation constraints was examined (case study 2). The investigations in the “no constraints” study resulted in a theoretical optimal harvest schedule for Coillte over the period 1998 to 2002. The solution showed great volume fluctuations from year to year, in terms of total volume, species, harvest type and product. It would be impossible to implement such a schedule, due to management, harvesting resources and industry requirements. However, the NPV achieved was used as a base to estimate the cost of applying management constraints in the second case study. This second study also showed that Coillte’s production smoothing process results in harvest schedules that are not feasible, as no adjustments for volume are included.
