Orthorexia Nervosa and Disordered Eating Attitudes, Self-Esteem and Physical Activity among Young Adults
No full textA relation between Orthorexia Nervosa (ON) and increased frequency of physical activity has been put in evidence by recent studies. It is well known that intense physical exercises are typically related to eating disorders, but its relationship with ON is still a subject of debate. Other transdiagnostic features could be necessary to conceptualize and understand ON; in this way, low self-esteem is related to eating behavior but is not still extensively investigated in ON, and, to date, data are so heterogeneous that they do not allow us to understand if this is a psychological feature somehow associated with ON. The current study aimed to assess whether disordered eating attitudes, self-esteem, and physical activity are associated with ON in young adults from Poland and Italy. Moreover, we investigated the differences by comparing lower and higher ON levels related to disordered eating attitudes, self-esteem, and physical activity. Our results indicated that a great concern about dieting significantly predicted problems associated with healthy eating, knowledge about healthy eating, and feeling positive about healthy eating. In addition, young adults with a high level of ON demonstrated higher levels of disordered eating attitudes and vigorous-intensity physical activity than young adults with a low level of ON. Future studies are needed to assess the direct effect of physical activity and self-esteem on ON
Grief after the child loss - virtual testimonies of mourning
No full textChild's death is commonly viewed as the most difficult experience for its parents. This kind of loss and escalation of dismal emotions related to this event allows us to speak of suffering mental pain. Mourning for the loss of child differs significantly from other forms of bemoaning; time is rarely a great healer in this case and a sense of void often continues for the entire lifetime. The range of emotional relationship with the child is so strong that the child's death is oftentimes interpreted by the parents as the irreversible loss of a tiny part of themselves. The author scrutinizes in the article a few dozen of short movies commemorating children's deaths. The author is trying to pinpoint typical parents reactions against the pain, grief and suffering after their loss. Materials presented in the article falI into the new trend of so-called cyber mourning which constitutes a perfect area for researching the contemporary dolorous funeral language.MATEUSZ SZUBERT - polonista i kulturoznawca, doktor nauk humanistycznych.

Higher levels of concern about dieting and moderate-intensity physical activity predict orthorexia nervosa among young adults
No full textINTRODUCTION: In some individuals, interest in healthy attitudes and behaviours towards food may show obsessive signs. Preoccupation with ‘healthful’ eating may contribute to orthorexia nervosa (ON) – a strong preoccupation with “healthy eating” manifested by the avoidance of all foods considered by the individual to be “unhealthy”. OBJECTIVES: The objective of the present study was to determine whether disordered eating behaviour, physical activity and self-esteem are predictors of ON in young adults. METHODS: Five hundred fifty-four Polish and Italian university students participated in the present study. Participants were asked to answer the Eating Habits Questionnaire, the Eating Attitudes Test, the International Physical Activity Questionnaire and the Rosenberg Self-Esteem Scale. RESULTS: Our findings found that higher levels of concern about dieting and moderate-intensity physical activity were related to ON. Particularly, higher levels of concern about dieting, bulimic behaviour and thoughts about food and moderate-intensity physical activity predicted problems associated with healthy eating. Higher levels of concern about dieting, self-esteem as well as self-control of eating and perceived pressure from others to gain weight were associated with knowledge of healthy eating. Whereas, higher levels of concern about dieting with country factor (Poland) predicted feeling positively about healthy eating. CONCLUSIONS: In ON treatment, reduction in symptoms and concerns characteristic of eating disorders and adequate levels of physical activity should be taken into consideration. DISCLOSURE: No significant relationships
Problemy pracy w koncepcjach programowych Delegatury Rządu na Kraj (1941-1945)
No full textKsiążka Wacława Szuberta ma wyjątkowy charakter i powinna spotkać się z ogromnym zainteresowaniem nie tylko środowisk naukowych związanych z prawem pracy, ubezpieczeniami społecznymi i polityką społeczną. Nie do przecenienia są również jej walory swoistego rodzaju świadectwa niezłomności Narodu Polskiego, który w najtrudniejszych latach okupacji hitlerowskiej nie tylko prowadził walkę z wrogiem, ale również, nie tracąc wiary w powodzenie tej walki, przygotowywał się do przyszłego okresu odbudowy struktur niepodległego państwa. Przejawem tego były prowadzone pod auspicjami Delegatury Rządu na Kraj prace koncepcyjne dotyczące kształtu życia społeczno-gospodarczego i politycznego w powojennej rzeczywistości. Nie ulega wątpliwości, że szczególną w tej perspektywie doniosłość miały koncepcje związane z przyszłym ustrojem pracy. Książka Profesora Szuberta ukazuje ten prawie nieznany obszar działalności Delegatury, a jest to tym cenniejsze, że Autor uczestniczył bezpośrednio w opisanych pracach koncepcyjnych i prowadząc rozważania mógł sięgać nie tylko do zasobów własnej pamięci, ale również do dokumentów, które zdołał zachować On sam oraz inni bohaterowie tamtych dni. Koncepcje programowe Departamentu Pracy i Polityki Społecznej były budowane w przeświadczeniu o potrzebie krytycznej kontynuacji tego, co w tym zakresie miało miejsce w II Rzeczpospolitej, z uwzględnieniem szczególnych potrzeb i uwarunkowań związanych z okresem przypadającym bezpośrednio po zakończeniu wojny światowej (odbudowa gospodarki i struktur organizacyjnych państwa), ale także z próbą zarysowania wizji rozwiązań, które powinny być realizowane docelowo, w późniejszym okresie. Ideologiczne i aksjologiczne podłoże tych wizji było zróżnicowane, zawsze jednak miały one bardzo widoczne zabarwione humanistyczne i były nacechowane pragnieniem budowy państwa silnego, ale i sprawiedliwego społecznie. W tej perspektywie należy postrzegać przewijające się w prezentowanych koncepcjach programowych założenia planowości gospodarki, uspołecznienia prawa własności, instytucjonalizacji stosunków pracy, obiektywizacji płac, pełnego zatrudnienia itp. Z pewnością nie wszystkie propozycje okazały się trafne (choćby odejście od zobowiązaniowego charakteru stosunku pracy), niektóre zostały zdeformowane przez patologie systemu „realnego socjalizmu” (choćby zasada planowości), to jednak wiele z nich po latach ciągle może odegrać pewną rolę „w wypracowaniu - jak pisał Profesor Szubert – optymalnych rozwiązań odpowiadających obecnym potrzebom”.Udostępnienie publikacji Wydawnictwa Uniwersytetu Łódzkiego finansowane w ramach projektu „Doskonałość naukowa kluczem do doskonałości kształcenia”.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
