Authors: Murray Sarah R. , Bhattacharya Sohinee , Stock Sarah J. , Pell Jill P. , Norman Jane E. 
Published: July 2019

Background: Twin pregnancy is associated with a threefold increase in perinatal death compared to singletons. The objective of this study was to determine the risk of perinatal death in twins by week of gestation and to quantify the effect of known risk factors. Methods: A cohort analysis was performed using data from the Aberdeen Maternity and Neonatal Databank (AMND). The exposure was gestational age at delivery and the primary outcome was perinatal death. Adjusted hazard ratios (aHRs) for perinatal death according to gestational age at delivery were determined by multivariate Cox proportional hazards regression modelling with robust standard errors to account for clustering in the twin infants. Confounders and risk factors quantified and adjusted for in the model included maternal age, smoking, parity, marital status and year of birth. Kaplan-Meier time to event analysis was used to determine the differences in survival according to chorionicity and assisted reproduction technologies (ART) conception status. Results: The population comprised of 7,420 twin babies born between 1950 and 2013 in the Grampian area of Northern Scotland. There were 272 stillbirths in the cohort (3.67%) and 273 neonatal deaths (3.68%). Compared to delivery at 37-38 weeks, delivery before 37 weeks was associated with a 2-fold increase in perinatal death. Monochorionic twins had a 2-fold increase in perinatal death compared to dichorionic twins (aHR 2.15, 95% CI 1.60-2.90). Twins conceived by ART did not have a greater risk of perinatal death compared to those naturally conceived (aHR 1.21, 95% CI 0.87-1.68) Conclusion: This study suggests that delivery of twins at 37-38 weeks is associated with the lowest risk of perinatal death.

Radio escolar: estudio evaluativo de una experiencia intergeneracional
Authors: Amado Lucia Abarrategui 
Published: July 2019

El envejecimiento poblacional es uno de los mayores retos de este siglo con implicaciones a todos los niveles, incluido el ámbito educativo. Por ello, la escuela debe acercarse a esta realidad desde sus propias estrategias, contribuyendo a generar una sociedad para todas las edades. Una de esas posibles estrategias pasa por los programas intergeneracionales. Por ello, abordamos el diseño, desarrollo y evaluación de un programa intergeneracional orientado a la creación de un podcast sobre el patrimonio cultural inmaterial, desarrollado en el cpi Plurilingüe Virxe da Cela de Monfero (Galicia, España) en coproducción con el cpi Castro Baxoi durante el curso 2016-2017. La metodología empleada en esta investigación ha sido la evaluación de programas a través de la observación participante. Esta técnica ha sido complementada con la realización de entrevistas a las personas implicadas en la experiencia. El propósito de esta evaluación ha sido analizar cómo el trabajo intergeneracional, empleando la radio como herramienta, favorece el aumento de la participación activa y el diálogo intergeneracional, pero también de la promoción de la inclusión y el aprendizaje a lo largo de la vida. Así, los resultados apuntan a que la radio puede fomentar el aprendizaje intergeneracional, la salvaguarda del patrimonio cultural inmaterial y el envejecimiento activo a través de su utilización en la escuela.

Abstract. Mechanization of postharvest handling and conditioning inflicts damage on the physical, physiological, and sanitary qualities of corn (Zea mays) seeds, resulting in significant economic loss. The mechanical damage is related to the compression strength and strain, and therefore to the moisture content (MC) and endosperm type. This study was conducted from 2012 to 2014 at the Montecillo and Chapingo agricultural institutes in Mexico, where physical properties such as volumetric weight; apparent density; rupture compression strength, strain, and energy; and endosperm type were evaluated for five corn seed cultivars (floury, semi-floury, floury-flint, semi-flint, and flint) at seven MC levels (8%, 12%, 16%, 20%, 24%, 28%, and 32% w.b.). The aim of this study was to develop moisture-strength, moisture-strain, and moisture-energy regression models for postharvest handling of corn to prevent quality loss due to mechanization. For three model groups, the relationship (1) between MC and rupture strain was linear and directly proportional for the five studied cultivars; (2) between MC and rupture strength was linear and directly proportional for the floury cultivar, inverse for the semi-flint and flint cultivars, and quadratic for the semi-floury and floury-flint cultivars; and (3) between MC and rupture energy was linear and directly proportional for the floury cultivar and quadratic for the semi-floury, floury-flint, semi-flint, and flint cultivars. The models obtained in this study might be used as a reference for better handling of corn seeds, as none of the five studied varieties had a uniformly superior rupture strength, strain, or energy at the studied MC levels. Floury endosperm types might be handled at high MC and flint endosperm types might be handled at low MC to avoid mechanical damage produced by static loads; both types of endosperm support greater energy loads, e.g., impact, at higher MC. Keywords: Compression, Corn quality, Flint endosperm, Floury endosperm, Moisture, Zea mays.
Strategi Kepemimpinan Pendidikan dalam Pengembangan MAN Propinsi DIY Perspektif Total Quality Management (TQM)
Authors: Subiyantoro Subiyantoro 
Published: July 2019

To date, the management of educational empowerment particularly in madrasah (Islamic schools) is still struggling in finding its precise form. The madrasahs are commonly managed base on merely the managers’ personal experience, without proper scientific conception. This happens due to unhealthy condition in which the managers are repressed and burdened by complicated bureaucratic matters. On the other hand, they are also required to compete in ever growing critical society. The main purpose of this research is to obtain the description of the Islamic educational empowerment strategies based on the Total Quality Management perspective, particularly in light of the educational leadership toward the development of the Madrasah Aliyah Negeri (State Islamic Senior High Schools) in the Province of Yogyakarta. Three methods of data gathering are employed in this research, namely in depth interview, participant observation, and documentation. The results show that, in empowering the Madrasah Aliyah, the leaders 1) rely on personal experience obtained from previous workplace, either being teacher or school principal; 2) perceive comparative study involving educational stakeholders, such as school committee, supervisors, and educational staff at Province level, as an effective tool in developing the madrasahs; 3) attend trainings or workshops held by the ministry of education; and 4) read books related to managerial tasks. Overall, the Total Quality Management can be observed through continuous improvement, culture change, reversed organization, costumers-organization good relationship, focus on costumers and the quality of teaching-learning process.

Published: July 2019

Ведення лісового господарства на типологічних засадах передбачає, що достовірно встановлені під час лісовпорядкування типи лісу та коректні значення лісівничо-таксаційних показників насаджень, зокрема запасів деревостанів, дають змогу планувати раціональні лісогосподарські заходи для підвищення продуктивності насаджень та ефективного використання лісових ресурсів. Відповідно до вимог лісовпорядної інструкції, лісівничо-таксаційні показники насаджень встановлюють окомірно-вимірювальним методом з визначеною нормативами точністю.
За даними лісовпорядкування, рівнинні букові деревостани та насадження за участю бука у складі представлені таксаційними виділами різної величини в 74 типах лісу, зокрема, в суборових умовах – у шести, сугрудових – у 36-ти та грудових – у 32-х, які охоплюють гігротопи від сухих до мокрих. Дослідники букових лісів виділяють значно меншу кількість типів лісу (від 25 до 35), в яких бук представлений як типотвірна, друга головна порода чи росте у складі деревостанів інших, переважно дубових, типів лісу. Наведена значна кількість типів лісу, які встановлені візуально під час лісовпорядкувальних робіт за наявними у насадженнях деревними видами, є штучно завищено, і не відповідає методологічним підходам до виділення типів лісу.
За результатами перевірки коректного встановлення основних таксаційних показників букових деревостанів, зокрема запасів стовбурової деревини на підставі видових чисел, встановлено, що для 36,7% від загальної кількості таксаційних виділів видові числа є некоректними (менші за 0,4 (до 0,158) чи більші за 1,0 (до 4,080), тоді як за таблицями ходу росту у букових деревостанах видові числа змінюються в межах 0,424-0,840.
Для вдосконалення системи безперервного лісовпорядкування доцільне вирішення проблеми розроблення обґрунтованого переліку типів лісу та їх діагностичних ознак, оцінки встановлених під час лісовпорядкування запасів і механізму актуалізації лісівничо-таксаційних показників електронної бази даних.
A comparative characteristic of fungal communities associated with Ips acuminatus in different regions of Ukraine
Authors: Davydenko Kateryna 
Published: July 2019

Pine bark beetles are typically associated with complexes of fungi that could reveal different functional interaction. Thus, previously nonaggressive bark beetle Ips acuminatus is considering now to be among the most serious pests of pine forest in Ukraine and other European countries and vectored fungal community is very important to assess total harm of this bark beetle. The aim of this study was to reveal the vectored fungal community associated with the pine engraver beetle, I. acuminatus with special emphasis on pathogenic fungi for further evaluation of harm bark-beetle - fungi association for Ukrainian forest.
In total, 288 adult beetles were collected from Scots pine trees at six different sites through Ukraine. DNA sequencing as fungal culturing from all beetles resulted in 1681 isolates and amplicons representing 42 fungal taxa. NCBI BLAST search revealed that the overall fungal community was composed of 94 species, of which 80.85% were Ascomycota, followed by Basidiomycota and unidentified fungal group, which accounted for 10.6% and 8.5 % of the total sequences, respectively. Among these, the most commonly detected fungi for pooling dataset were Sphaeropsis sapinea (23.6%), Cladosporium pini-ponderosae (19.44%), Ophiostoma ips (19.1%), Ophiostoma canum (19.1%) and Cladobotryum mycophilum (18.06%). In the pooled dataset of isolates and amplicons for each site, Shannon diversity indices ranged between 1.9 and 2.9 while Simpson diversity index varied between 0.69 and 0.89 indicating rich species diversity.
In total twelve ophiostomatoid species were detected. All ophiostomatoid fungi were showing varying degrees of virulence and O. minus was the most aggressive fungus in previous studies. It is concluded that I. acuminatus vectors a species-rich fungal community including pathogens such as ophiostomatoid fungi, Sphaeropsis sapinea, different needle pathogens and wood decay fungi that seems to be very important for the assessment of threat of I. acuminatus to the pine forest in Ukraine.
Вплив пінополістиролу на процес прогрівання стружково-полімерного пакета

Published: July 2019

Досліджено вплив пінополістиролу на процес прогрівання стружково-полімерного пакета в процесі пресування легких стружкових плит. Для фіксації температури, до якої прогрівається внутрішній шар стружково-полімерного пакета, використано мультиметр з приєднаною до нього термопарою, яку було розміщено всередині пакета. Пресування здійснювалося за питомого тиску пресування 2,4 МПа і температури плит преса 200 С. Пресували легкі стружкові плити (без пінополістиролу та з вмістом пінополістиролу 4, 7, 10%) розмірами 300×300×18 мм і щільністю 350, 450 і 550 кг/м3, личковані лущеним шпоном. Встановлено, що тривалість прогрівання стружково-полімерного пакета легких стружкових плит зменшується за збільшення в них вмісту пінополістиролу до 7%, після чого починає зростати. Додавання пінополістиролу до стружки спричиняє заповнення пустот з одночасним зростанням кількості контактів між стружкою, через яку передається тепло від периферії до центру стружково-полімерного пакета. Зростання вмісту пінополістиролу в стружково-полімерному пакеті більше 7% зумовлює сповільнення його прогрівання через те, що об’єм пінополістиролу є більшим, ніж стружки, а теплопровідність пінополістиролу є меншою порівняно з деревиною. Зі збільшенням щільності плит з 350 до 550 кг/м3 тривалість прогрівання стружково-полімерного пакета зменшується. Більша маса стружки в одиниці об’єму пакета зменшує його пористість, збільшує теплопровідність і, як наслідок, спричиняє швидше його прогрівання. Значення тривалості прогрівання середнього шару пакета легких стружкових плит до 100 oС із вмістом пінополістиролу 7% є меншим на 12-33%, ніж плит без пінополістиролу. Отримані результати дають змогу підвищити ефективність процесу пресування легких стружкових плит з вмістом пінополістиролу.
Is Women's Job Satisfaction Higher than Men's? Self-Selection, Expectations or Utility Function
Authors: Sánchez-Sánchez Nuria , Fernández Puente Adolfo C. 
Published: July 2019

This paper examines the paradox between high relative levels of job satisfaction and the characteristics of women's jobs compared to men's in Spain. Three hypothesis are considered: i) the existence of a selection bias when participating in the labour market; ii) of the presence of adaptive job satisfaction; and iii) the existence of differences related to preferences of different nature to strictly labour issues.
The study shows that, although having lower working conditions, women are more likely to be satisfied at work than men are. This paradox persists regardless of the inclusion of a great range of variables of different nature (objective and subjective), the age group and educational level under consideration. The Oaxaca-Blinder decomposition suggests that women's preferences are actually influencing the differences in job satisfaction. However, it is not demonstrated that these differences disappear as age decreases or educational level increases. The probable existence of a “glass ceiling” that prevents women from having access to posts of greater responsibility and higher wages could cause that women who actually reach them are more satisfied than their male colleagues. As the labour market and society become more equal, this paradox might dilute.
Adolescents’ compulsive sexual behavior: The role of parental competence, parents’ psychopathology, and quality of parent–child communication about sex
Authors: Efrati Yaniv , Gola Mateusz 
Published: July 2019

Background and aimsCompulsive sexual behavior (CSB) has implications for clinical and non-clinical adult populations. Disposition to CSB has been shown to influence adolescence sexual behaviors, but the development of adolescents’ disposition toward CSB has yet to be examined in the family context. In this study, we investigated whether parent–adolescent communication mediates the links between parental characteristics and adolescents’ CSB.MethodsThe sample included 275 Israeli families [triad of mothers (age = 34–63 years,M = 45.48,SD = 5.46), fathers (age = 36–83 years,M = 48.33,SD = 6.63), and one adolescent (48.2% boys, 51.1% girls; age = 14–18 years,M = 16.23,SD = 1.18)]. Parents completed measures of psychopathology, parental self-esteem, and parental self-efficacy, and adolescents completed measures of quality of sex-related communication and CSB.ResultsThe results indicate that, for girls, higher maternal self-esteem and lower psychopathology were linked with better sex-related communication and so with lower CSB. For boys, only parental religiosity was linked with the quality of sex-related communication and CSB, with religious parents having better communication than secular ones.DiscussionThe findings provide an opportunity for researchers to gain a better insight into the dynamics of familial factors in the development of CSB among adolescents.
Does Gender Significantly Predict Academic, Athletic Career Motivation among NCAA Division I College Athletes
Authors: Tudor Margaret , Ridpath B. David 
Published: July 2019

American society has had college athletics at its core for over a century (Rader, 2009) and is ubiquitous in University life. College athletes’ performances both on and off the field have been scrutinized in both popular and academic literature. Other examples include the documentation in student development literature that meaningful engagement outside traditional classroom settings can have positive effects on a student’s (athlete or not) personal development (Pascarella & Terenzini, 2005). College athletes’ individual experiences have received considerable attention in the popular media and literature as the pressures to perform both athletically and academically are vast (Benford, 2007; Meyer, 2005). Previous studies have explored the athletic environment in terms of the emergence of leadership, team dynamics, team cohesion, and the motivational climate (Adie, Duda, & Ntoumanis, 2008; Allen, & Howe, 1998; Balaguer, Duda, & Crespo, 1999; Medic, Mack, Wilson, & Starkes, 2007; Tsang, 2007). Other studies have focused more on individual attributes such as motivation to perform and participate, perceived ability, perceived competence, personal satisfaction, enjoyment, and social status (Amorose, & Horn, 2001; Hollembeak, & Amorose, 2005; Reinboth, & Duda, 2004; Sheldon, & Eccles, 2005; Van-Yperen, & Duda, 1999). The purpose of this study is to examine the effects of gender (men’s vs. women’s sports) on motivation towards academics, athletics, and career choice. Data were gleaned from male and female athletes at one large Midwestern NCAA Division I University using the Perceived Motivational Climate in Sport Questionnaire-2 (PMCSQ-2) and the Student Athlete’s Motivation toward Sports and Academics Questionnaire (SAMSAQ). Data are discussed and analyzed using various statistical methods and using Harter’s (1978) theory of perceived competence and Nicholls (1984) perceived theory of motivational climate to answer the theorized research question and hypotheses.
