Development of a patient assessment to meet the needs of patients suffering from advanced non-oncological diseases – the KOPAL trial
No full textAbstract Background Patients suffering from progressive non-oncologic chronic diseases are primarily treated in primary care. Early integration of palliative care (PC) can improve patients’ quality of life and reduce burdensome physical symptoms. To guide interprofessional counselling between GPs and specialist palliative home care teams, we developed an aide memoire for patients diagnosed with advanced non-oncological chronic diseases, the KOPAL conversation guide, as part of the KOPAL trial. The aim of this study was to ensure the conversation guide covers all relevant care aspects in order to reveal individual gaps and needs in healthcare. Methods We conducted three focus groups including four patients, seven health care providers, and five stakeholders. During each group, a draft of the conversation guide was discussed, revised, and consented from the respective perspectives. Results The final KOPAL conversation guide contains eight key topics: living with the illness, physical, emotional, personal, and social situation, information and communication, control and autonomy, emergency management. Each topic refers to a number of related subtopics listed in each respective thematic section. The conversation should start with the introductory question referring to the patient’s current well-being. At the end, patients are asked to state their primary concern based on the conversation. Conclusions The KOPAL conversation guide is a broad evaluation and communication tool. It covers potential PC needs of non-oncological patients and provides a basis for interprofessional case planning, and counselling. Applying the guide may help to bridge gaps in communication between general and specialist PC professionals as well as between professionals and patients
Batesian mimicry in jumping spiders (Araneae: Salticidae)
No full textJan Kopal Batesovské mimikry u skákavek (Araneae: Salticidae) Abstrakt Během své evoluce skákavky vytvořily nezměrné množství různých forem a strategií, které jim umožnily přežít v různých nikách. Nepřekvapí nás tedy, že se setkáme s herbivorními druhy, zdatnými predátory, ale i vykradači hnízd ostatních živočichů. Zároveň však kvůli dennímu způsobu života jsou napadáni různými predátory, před kterými se musí chránit. Proto u některých z nich vznikly mimikry, které se snaží odvrátit útoky těchto predátorů. Velmi významnou skupinou pak představují druhy, které začaly napodobovat mravence, u kterých si povšimneme nápodoby vzhledu, chování a v některých případech i specifických chemických sloučenin. Tato mravenčí podoba pak nezávisle vznikala u vzdáleně příbuzných druhů na různých místech světa. Vzhledem k rozpětí tohoto tématu se tato práce snaží shrnout zatím zjištěné poznatky a případně poukázat na chybějící informace, či nastínit možné směry dalšího výzkumu. klíčová slova: skákavky; Salticidae; Batesovské mimikry; myrmekomorfie; myrmekoidie; myrmekofilie; myrmekofágie; fylogeneze; ochrana před predátoryJan Kopal Batesian mimicry in jumping spiders (Araneae: Salticidae) Abstract During their evolution, jumping spiders have developed an immense variety of forms and strategies that have enabled them to survive in different niches. It is therefore not surprising that we encounter herbivorous species, skilled predators, and even nest raiders of other animals. However, due to their diurnal lifestyle, they are attacked by various predators from which they must protect themselves. Consequently, some have developed mimicry to deter predator attacks. Avery significant group comprises species that have started to mimic ants, displaying imitations of appearance, behavior, and in some cases, specific chemical compounds. This ant mimicry has independently arisen in distantly related species in different parts of the world. Given the scope of this topic, this paper aims to summarize the findings to date and potentially highlight missing information or suggest possible directions for further research.

THE FREQUENCY OF CEPHEID BINARIES
No full textWe summarize the methods now available to detect the presence of companions to Cepheids, and then we analyze the results of the application
of the recent photometric method proposed by Fernie (1980). If applied to the set of VBLUV observations of southern Cepheids carried out by Pel (1976), this method gives a frequency of about 25°/oJ which is consistent with the more recent spectroscopic determinations (Gieren, 1981). The importance of the IUE satellite to directly observe the U flux emitted by the B-companion is emphasized
The Benefits of Being Economics Professor A (and not Z)
No full textAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering
Final word on Jersey Dutch
No full textIn this article, William Z. Shetter compares and contrasts the dialects that developed between different Dutch colonies in the New World. He explores in-depth the nuances of Jersey Dutch, and provides theories to explain how Dutch and colonial languages blended. The article is reprinted from American Speech, December 1958, Volum XXXIII, No. 4
ON A POSSIBLE LI~KAGE BETWEEN W-TYPE WUMa SYSTEMS AND THE SHORT PERIOD RSCVn-LIKE BINARIES
No full textWe analize the general properties of a group of WUMa-type binaries, which show RSCVn-like activity. The position of these stars in the colour-density and mass-orbital momentum diagrams is studied, but no definite answer can be given on the linkage between short period RSCVn systems (SPG) and WUMa systems with RSCVn-like activity (WWG)

Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
