Cílem této studie je ověřit psychometrické vlastnosti české adaptace zkrácené osmipoložkové Škály vytrvalosti (Grit-S) na základě analýzy položek, reliability ve smyslu vnitřní konzistence, obsahové a souběžné validity. Výzkumný soubor čítal 338 respondentů, z nichž bylo 209 (61,8 %) ženského a 129 (38,2 %) mužského pohlaví ve věkovém rozpětí 15-76 let (M = 28,39; sd = 10,5). Výsledky svědčí o uspokojivé reliabilitě i validitě škály. Zároveň byl nalezen signifikantní pozitivní vztah skóru této škály s věkem. Výsledky jsou konfrontovány s psychometrickými vlastnostmi originální škály a diskutovány ve světle zahraničních výsledků. Česká adaptace Grit-S je součástí tohoto příspěvku. and The aim of this study is to test the psychometric properties of Czech adaptation of 8-item Short Grit Scale based on item analysis, internal consistency, content and convergent validity. The sample of 338 respondents included 209 (61.8 %) female and 129 (38.2 %) male participants between 15 and 76 years of age (M = 28.39; sd = 10.5). The results suggest satisfactory reliability and validity. Comparative analyses of demographic factors (age and gender) revealed a significant positive relationship between age and grit. The results are compared with the psychometric properties of the original scale and related studies. The Czech version of Grit-S is attached.
Snow production results in high volume of snow that is remaining on the low-elevation ski pistes after snowmelt of natural snow on the off-piste sites. The aim of this study was to identify snow/ice depth, snow density, and snow water equivalent of remaining ski piste snowpack to calculate and to compare snow ablation water volume with potential infiltration on the ski piste area at South-Central Slovak ski center Košútka (Inner Western Carpathians; temperate zone). Snow ablation water volume was calculated from manual snow depth and density measurements, which were performed at the end of five winter seasons 2010–2011 to 2015–2016, except for season 2013–2014. The laser diffraction analyzes were carried out to identify soil grain size and subsequently the hydraulic conductivity of soil to calculate the infiltration. The average rate of water movement through soil was seven times as high as five seasons’ average ablation rate of ski piste snowpack; nevertheless, the ski piste area was potentially able to infiltrate only 47% of snow ablation water volume on average. Limitation for infiltration was frozen soil and ice layers below the ski piste snowpack and low snow-free area at the beginning of the studied ablation period.
The Lama forest is the largest natural forest in southern Benin, and one of the last remnant forests within the Dahomey Gap. It harbours several species of major importance in terms of conservation. Small mammals are known to represent more than 80% of the African mammalian species diversity but they have received little attention in Benin. In this article we present the results of the first terrestrial small mammal species inventory (murid rodents and shrews) in the Lama forest. In September and October 2007, we captured 280 small mammals belonging to 12 species, identified by morphological and genetic analysis. We also provide detailed cytogenetic data for six of the 12 captured species. For five of them, we compare our data with previously published karyotypes, and for the sixth one (Hylomyscus pamfi), the karyotype is published here for the first time. Two of the captured species are closed-forest specialists (Praomys misonnei, H. pamfi), and H. pamfi is endemic to the Dahomey Gap region. Our results are congruent with those obtained on other animal groups, and highlight the importance of the Lama forest for the conservation of the country's forest biodiversity.
Twenty species (sixteen adult and four larval) of parasitic nematodes belonging to the Ascaridoidea, Camallanoidea, Cosmocercoidea, Dioctophymatoidea, Habronematoidea, Oxyuroidea, Seuratoidea, and Thelazioidea were collected from freshwater fishes of the Congo River basin in the Democratic Republic of the Congo and the Central African Republic in 2008 and 2012, respectively. Based on light and scanning electron microscopical examination, many species are redescribed in detail. This material also contained four previously unknown species, Labeonema longispiculatum sp. n. from Synodontis acanthomias Boulenger, Gendria longispiculata sp. n. from Schilbe grenfelli (Boulenger), G. sanghaensis sp. n. from Schilbe marmoratus Boulenger, and Cucullanus congolensis sp. n. from Auchenoglanis occidentalis (Valenciennes). The new species L. longispiculatum is mainly characterised by conspicuously long (210-228 µm) spicules, approximately twice as long as those in other congeners, the length (45-48 µm) of the gubernaculum and the host family (Mochokidae), whereas G. longispiculata by very long (1.2 mm) spicules, the shape of the oesophagus and cephalic vesicle, distribution of postanal papillae and the host family (Schilbeidae). Main characteristic features of G. sanghaensis are the presence of a hexagonal oral aperture surrounded by lip-like structures, the posterior portion of the oesophagus moderately expanded, spicules and the gubernaculum 414-438 µm and 54-57 µm long, respectively, deirids located at the level of the posterior end of the oesophagus and the absence of cervical alae. Cucullanus congolensis differs from congeneric species parasitising African freshwater and brackish-water fishes mainly in the absence of a ventral precloacal sucker and lateral preanal papillae, the presence of a large median precloacal papilla-like formation, spicules 480-489 µm long and the location of the excretory pore in the regio, František Moravec, Miloslav Jirků., and Obsahuje bibliografii
Based on material collected from Rhinella cf. margaritifera (Laurenti) and Rhi. marina (Linnaeus) (Anura: Bufonidae) during a parasite survey of the herpetofauna of French Guiana, updated descriptions of Rhabdias androgyna Kloss, 1971 and R. fuelleborni Travassos, 1926 are presented. In addition to metrical data, which may overlap in closely related species, emphasis is placed on qualitative characters. Rhabdias androgyna is distinguished by the unique presence of an outer and inner cephalic cuticular inflation, a shoulder-like broadening of the body at the anterior end, a wide and shallow buccal capsule (average buccal ratio 0.36) with serrated lumen in apical view, a prominent anterior dilatation of the oesophagus, and the presence of an additional posterior dilatation anterior to the oesophageal bulb. Characters that may help to differentiate R. fuelleborni from closely related species parasitising the Rhi. marina species group are the presence of six relatively uniform lips, and the division of the buccal capsule into an anterior and posterior segment, with differently structured walls. Both the presence of R. androgyna and R. fuelleborni in French Guiana constitute new geographic records. A single specimen of Rhabdias sp. is described from Pristimantis chiastonotus (Lynch et Hoegmood) (Anura: Craugastoridae). This species differs from all its Neotropical congeners by the distinct globular swelling of its head, similar to that seen in only one Palaearctic and one Afrotropical Rhabdias species. A list of species of Rhabdias parasitising amphibians in the Netropical Realm is also provided., Yuriy Kuzmin, Louis H. du Preez, Kerstin Junker., and Obsahuje bibliografii
Fourteen species (twelve adult and two larval) of nematodes belonging to the Ascaridoidea, Camallanoidea, Cosmocercoidea, Habronematoidea, Oxyuroidea, Seuratoidea and Trichinelloidea were collected from fishes in the Sudan (River Nile and Atbara Dam Lake), whereas only four species (one adult and three larval) of the Ascaridoidea, Camallanoidea, Dioctophymatoidea and Trichinelloideafrom fishes in Ethiopia (Lake Tana). The Sudanese material also contained two previously unknown species, Cucullanus mormyri sp. n. from Mormyrus caschive Linnaeus (type host), Mormyrus sp. and Marcusenius cyprinoides (Linnaeus) (all Mormyridae), and Procamallanus (Spirocamallanus) pseudospiralis sp. n. from Synodontis schall (Bloch et Schneider) (type host), S. frontosus Vaillant and S. nigrita Valenciennes (all Mochokidae), which are described based on light and scanning electron microscopical studies. Cucullanus baylisi Campana-Rouget, 1961, a little-known parasite of Synodontis spp., is redescribed in detail. A key to Procamallanus (Spirocamallanus) spp. from African inland fishes is provided. Falcaustra guiersi Vassiliadès, 1973 is considered a junior synonym of F. hexapapillata (Khalil, 1962). The findings represent several new host and geographical records. Cucullanus baylisi Lakshmi, 2000 (= a homonym to C. baylisi Campana-Rouget, 1961) is re-named as C. dubius nom. n. and is considered a species inquirenda., František Moravec, Tomáš Scholz., and Obsahuje bibliografii
V předcházející studii (Cígler & Rudá, 2021) se nám nepodařilo prokázat dostatečnou vnitřní konzistenci a faktorovou validitu dotazníku SPARO. Pro posouzení vhodnosti jeho využití v praxi jsou nicméně důležité ještě další psychometrické parametry. V tomto navazujícím výzkumu se proto pokusíme ověřit jeho souběžnou validitu oproti dotazníkové baterii MMPI 2. Její výhodou je mezinárodní popularita, díky níž se může opřít o řadu zahraničních studií. S využitím rozsáhlého vzorku policistů a uchazečů o práci u policie se nám nicméně nepodařilo souběžnou validitu uspokojivě demonstrovat. Nedostatečná je jak konvergentní, tak i divergentní validita hlavních komponent, obecných faktorů i skóre věrohodnosti (L) dotazníku SPARO vůči vybraným škálám MMPI 2, a to s výjimkou škály emocionální variabilnosti (EM). Vedlejším výstupem naší studie je ověření vnitřní konzistence a faktorové struktury jednotlivých škál dotazníku MMPI 2, protože jiné české empirické studie na toto téma neexistují. Musíme konstatovat, že jak reliabilita, tak i faktorová validita MMPI 2 rovněž není uspokojivá. Závěrem argumentujeme, že použití dotazníku SPARO v běžné praxi nelze v žádném případě doporučit. Opatrné použití dotazníku MMPI 2 je podle nás možné s ohledem na uspokojivé zahraniční výsledky, je však nezbytný další český výzkum, a to zejména po stránce prediktivní validity. and In the previous study (Cígler & Rudá, 2021), we were not able to confirm satisfactory internal consistency and factor validity of the SPARO questionnaire. However, further psychometric properties are also necessary to consider the questionnaire's validity and usefulness in practice. In this follow up study, we examined its criterion validity to MMPI-2, which is used globally and thus has broader empirical support. Despite that, we did not find any support for neither convergent nor divergent validity of the main components, general factor, and the credibility score (L) of SPARO questionnaire to selected MMPI-2 scales. The only exception was the emotional variability scale (EM). As a minor result, we also examined the internal consistency and factor validity of MMPI-2 scales as no other Czech study concerning the questionnaire exists. Neither reliability nor factor validity was satisfactory. Finally, we argue that using the SPARO questionnaire in regular practice cannot be recommended. Cautious use of the MMPI-2 is possible, regarding international validation studies, however, further Czech research is needed, especially in the predictive validity.
The knowledge of spatio-temporal dynamics of soil moisture within the catchment is very important for rainfall– runoff modelling in flood forecasting. In this study the comparison between remotely sensed soil moisture and soil moisture estimated from the SHETRAN hydrological model was performed for small and flashy Jičinka River catchment (75.9 km2) in the Czech Republic. Due to a relatively coarse spatial resolution of satellite data, the satellite soil moisture data were downscaled, by applying the method developed by Qu et al. (2015). The sub-grid variability of soil moisture was estimated on the basis of the mean soil moisture for the grid cell and the known hydraulic soil properties. The SHETRAN model was calibrated and verified to the observed streamflow hydrographs at the catchment outlet. The good correlation between the two different soil moisture information was obtained according to the majority of applied criteria. The results of the evaluation criteria indicate that the downscaled remotely sensed soil moisture data can be used as additional criteria for the calibration and validation of hydrological models for small catchments and can contribute to a better estimation of parameters, to reduce uncertainties of hydrological models and improve runoff simulations.
Výzkumná studie se zabývá pohledem školních psychologů na klady a zápory jejich profese. Dále je výzkum zaměřen na zjištění úrovně spokojenosti školních psychologů se svou prací. Z výsledků vyplývá, že mezi nejčastěji zmiňované kladné aspekty práce školních psychologů patří možnost přímé práce s klientem, volnost časová i ve způsobu pojetí práce a rozmanitost. Naopak nejčastěji zmiňovanými zápory byly náročné vztahy na pracovišti, nejasná role a osamocenost. Velká část výzkumného souboru (N = 61, z toho 59 žen) je pracovně spokojena. Byla nalezena statisticky významná souvislost mezi touto spokojeností a délkou praxe i výší úvazku školních psychologů. and The research study discusses the view of school psychologists on the positive and negative aspects of their profession. In addition, the research aims to discover to what extent school psychologists are satisfied with their work. The results show that the most frequently mentioned positive aspects of the work of school psychologists are the possibility of direct work with clients, a flexible work schedule and a flexibility in working approach and diversity. On the contrary, the most frequently mentioned disadvantages are difficult relationships in the workplace, unclear role, and loneliness. A large part of the respondent sample (N = 61, 59 women) are job-satisfied. A statistically significant correlation was found between job satisfaction and the practice length as well as the number of weekly working hours.
Prvním cílem při vývoji evidence-based systému pro Zulligerův tabulový test (ZTT) je vytvoření podmínek umožňujících definici psychometricky relevantních vyhodnocovacích postupů a validizaci interpretačních závěrů. Psychometricky adekvátní vyhodnocení a validní interpretace jsou významně ovlivněny počtem podaných odpovědí na podnětový materiál. Cílem aktuální studie je proto ověření možnosti standardizace celkového počtu odpovědí skrze srovnání vlivu tří instrukcí na celkový počet podaných odpovědí a vybrané skórovací proměnné. Studie byla provedena na 45 respondentech ve věku 19 až 33 let. Jednalo se o 40 žen a 5 mužů, kteří byli náhodně rozděleni do tří skupin. Každé skupině byl ZTT administrován s rozdílnou instrukcí. Zapojena byla tradiční instrukce pro ZTT (Michal, 1998), instrukce podle Komprehenzivního systému (CS) pro ZTT (Mattlar et al., 1993) a autorským kolektivem vyvinutá instrukce na principu R-optimized. Při analýze dat byla využita popisná statistika, Kendallův korelační koeficient, Brownův-Forsytheův test a Anderson–Darlingův test pro více výběrů. Výsledky odhalily, že všechny instrukce přinášejí dostatečný počet odpovědí, pouze R-optimized instrukce však standardizovaný počet. V případě tradiční instrukce pro Zulligerův test a instrukce podle CS pro ZTT byla identifikována souvislost mezi počtem odpovědí a částí sledovaných proměnných. Získané výsledky naznačují, že pro evidence-based přístup je potenciálně přínosná zejména R-optimized instrukce. Limitem studie je malý rozsah výzkumného souboru. and When developing the evidence-based system for Zulliger inkblot test (ZTT), the first objective is to create conditions allowing us to define psychometrically relevant evaluation procedures and validate the conclusions of interpretation. The adequacy of psychometric evaluation and validity of interpretations are significantly influenced by the number of responses provided to the stimulant material. The aim of the present study is therefore to verify the possibility of standardization of the total number of responses by comparing the influence of three various types of instructions on the total number of provided responses and the selected scoring variable. The study was conducted on a group of 45 respondents (5 men and 40 women) aged between 19 and 33. These were randomly divided into three groups. Each group was given ZTT with different instructions: the traditional instruction for ZTT (Michal, 1998), the instruction according to Comprehensive System (CS) for ZTT (Mattlar et al., 1993), and the instruction based on the R-optimized principle developed by authors of this study. The data analysis employed description statistics, Kendall´s correlation coefficient, the Brown–Forsythe test and K-Sample Anderson-Darling Test. The results showed that all instruction types resulted in a sufficient number of responses; however, only the R-optimized instruction provided a standardized number of responses. A correlation between the number of responses and some of the observed variables was identified in the case of the traditional instruction for ZTT and the instruction according to CS for ZTT. The obtained results suggest that the R-optimized instruction is particularly beneficial for the new evidence-based approach. The limitation of the study is the small sample size.
