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
On The Susceptibility of PID in Perovskite Modules: A Comparison of ITO and Cu Contacts
No full textOrganic-inorganic perovskite lead halide solar cells (PSCs) have received increasing interest in the last decade. PSCs already achieve record efficiencies above 25%. However, long-term stability is still a problem, especially when transitioning from cells to modules.
One of the described long-term stability problems at the module level is Potential-induced degradation (PID), caused by the voltage build-up by modules connected in series.
PID is extensively investigated within crystalline silicon PV, while very little is known for perovskites. Carolus et al. reported nearly complete efficiency losses within 18 hours of a PID stress test, indicating their high susceptibility to PID[1]. In order to tackle PID-related stability issues and make commercialization a reality, it is crucial to retrieve insights into the physics of the PID mechanism.
This study investigates and compares the PID mechanism within p-i-n CsFAPbIBr perovskite modules with either a copper (Cu) or an indium tin oxide (ITO) rear contact. Several soda-lime glass-glass configured 5.5 x 5.5 cm² mini-modules were PID stressed from the p-side at 40⁰C and 1000 V for 192 hours using the foil method. Intermediate current-voltage measurements (IV) and electroluminescence (EL) images were taken to investigate the PID progress.
The ITO contacted perovskite modules illustrate an incubation period of about 100 hours. A slight drop in short-circuit current (Isc) and a modest increase in series resistance can be observed within this incubation period.
Subsequently, a significant drop in Isc and increase in series resistance are noticeable. Evidently, after 192 hours, an additional decrease in shunt resistance is noticeable, resulting in a total relative loss of efficiency of almost 80%. The EL images illustrate no significant differences in the incubation period, although the formation of inhomogeneities can be observed further in the degradation process[2].
The Cu-contacted perovskite modules are significantly more prone to PID than their ITO counterpart. Similarly, the drop in Isc and increase in series resistance can be observed; however, no incubation period is present.
Analogous to crystalline silicon, it is hypothesized that positively charged sodium ions migrate out of the cover glass towards the PV cell. Hence, the ions can alter the conductivity of the contacts or migrate deeper into the stack and form inhomogeneities in the perovskite material[3]. However, additional PID stress tests are ongoing to validate the hypothesized findings. Furthermore, microstructural analysis is necessary to designate this degradation mechanism's root cause and retrieve more insights into its physical behavior and kinetics

Moth abundance changes and consequent bottom-up effects on birds in boreal forests
No full textAbstract
Many insect populations are declining, although the exact details of the magnitude and geographic spread of these declines are still unknown. Considering how insects are vital for the functioning of terrestrial ecosystems, evidence of widespread declines has raised concern about cascading effects across trophic levels. The boreal forests of Finland, sources of high-quality long-term monitoring data, offer an ideal setting to expand insect abundance research and explore how climate and environmental change affect insect populations and their trophic interactions. My aim is to investigate (I) how the biomass of moths has changed over time and which ecological and life-history traits could explain these trends, (II) whether moth biomass has a bottom-up effect on insectivorous forest birds at the functional group level, and (III) whether such bottom-up effects can be detected at the species level. I used state-of-the-art joint dynamic species distribution models (JDSDMs) to address the aims. My results suggest that: (I) there has been no decline in the total biomass of moth functional groups across Finland in the past 27 years. Instead, biomass remained stable for most groups, while several were increasing. There was also considerable geographical variation in abundance trends. (II) Abundance fluctuations of insectivorous forest birds were positively associated with fluctuations in moth biomass, particularly among early-season moths in the north-boreal zone, where seasonal constraints on breeding are most pronounced. These bottom-up effects were observed for birds that were residents or long-distance migrants. The strength of these associations declined towards the south, indicating regional variation in the strength of trophic interactions. (III) At the species level, moth bottom-up effects on birds were generally weak and inconsistent, with a few weak but biologically meaningful patterns emerging in the north-boreal zone. The unexpectedly weak bottom-up effects indicate that forest birds may possess greater foraging flexibility and resilience than previously assumed, enabling them to cope with fluctuations in specific prey resources. This dissertation emphasizes how integrating long-term biodiversity datasets can reveal community-level trophic interactions and provide new opportunities for understanding the effects of global change on ecosystem functioning.

Hyönteispopulaatioiden on maailmanlaajuisesti havaittu taantuneen voimakkaasti. Koska hyönteiset suorittavat kriittisiä toimintoja maaekosysteemeissä, havainnot niiden laajamittaisesta vähenemisestä ovat herättäneet huolta mahdollisista trofiatasojen välisistä kerrannaisvaikutuksista. Tästä huolimatta tiedot hyönteisrunsauksien pitkäaikaismuutoksista tai niiden vaikutuksista ovat puutteellisia jopa hyönteistuntemukseltaan edistyksellisessä pohjolassa. Suomen boreaalisista metsistä kerättyjen pitkien seuranta-aineistojen avulla voidaan tutkia ilmaston- ja ympäristönmuutosten vaikutuksia hyönteisrunsauksiin ja hyönteisten rooleihin ravintoverkoissa. Tutkin (I) miten yöperhosten biomassa on muuttunut viime vuosikymmeninä, sekä mitkä ekologiset- tai elinkierto-ominaisuudet selittävät lajienvälisiä eroja runsausmuutoksissa; (II) säätelevätkö yöperhosryhmien runsausvaihtelut metsälintujen pesimätiheyksiä, kun tarkastellaan lintuja joko niiden lajiominaisuuksien perusteella ryhmiteltyinä, tai (III) lajikohtaisesti. Käytin yhteisöekologian uusimpia ja väkevimpiä työkaluja, dynaamisia lajien yhteisesiintymismalleja (JDSDM). Tulosteni mukaan (I) minkään tutkimani yöperhosryhmän kokonaisbiomassa ei ole vähentynyt koko Suomen mittakaavassa viimeisten 27 vuoden aikana. Perhosryhmien sisällä tiheysmuutoksissa oli kuitenkin suurtakin maantieteellistä vaihtelua. (II) Yöperhosten, ja etenkin kasvukauden alussa toukkana esiintyvien lajien runsausvaihtelut selittivät seuraavan vuoden lintujen pesimätiheyksiä varsinkin pohjoisboreaalisella metsävyöhykkeellä. Yöperhosravinnon saatavuus vaikutti etenkin paikkalintujen sekä pitkänmatkan muuttajien pesimätiheyksiin. Vaikutusten heikkeneminen siirryttäessä eteläisemmille vyöhykkeille osoittaa maantieteellistä muuntelua ravintoverkkovuorovaikutusten voimakkuuksissa. (III) Yöperhosravinnon saatavuuden vaikutukset yksittäisten lintulajien pesimätiheyksiin olivat pääasiassa heikkoja ja epäjohdonmukaisia, muutamia pohjoisboreaalisella alueella havaittuja biologisesti mielekkäitä yhteyksiä lukuun ottamatta. Voimakkaiden yhteyksien puuttuminen voi tarkoittaa, että metsälinnut saattavat olla ravinnonhankinnassaan joustavampia kuin on yleisesti ajateltu, mikä helpottaisi niitä selviämään tiettyjen saaliseläinten runsausnotkahduksista.

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
Využití sociálních médií v B2B prodeji
No full textTato diplomová práce se zabývá tím, jak mohou B2B obchodníci využívat sociální média v prodeji. Na základě systematické rešerše literatury, autor zjistil, že akademici, zkoumající danou problematiku, navrhují další výzkum, a to: v kterých konkrétních krocích se dají využít sociální média v prodeji (Salo, 2017). Autor se na základě toho rozhodl zjistit, jaké sociální sítě, různé technologie a pluginy se dají využít v B2B prodeji - tzv. social sellingu. Social selling se v této práci týká primárně procesu akvizice a okrajově péčí o stávající zákazníky. Autor si vybral kvalitativní průzkum pomocí 10 hloubkových polo-strukturovaných rozhovorů, aby odhalil jak, která sociální média to jsou, tak i motivaci prodejců, proč tato média používat/nepoužívat. Aby autor dodržel správnost vyhodnocení výsledků, data byla analyzována pomocí Tématické analýzy, která v této studii vykrystalizovala 2 hlavní strategické přístupy v social sellingu. Tyto přístupy (tzv. Push a Pull strategie) obsahují praktické příklady a konkrétní aktivity, které mohou prodejci využívat v každodenní praxi. Tyto výsledky jsou prezentovány s důrazem na praktičnost a jednoduchost implementace. Tvoří proto hlavní přínos autorovo výzkumu. V poslední části autor zmiňuje výzvy a manažerská doporučení, které mohou obchodníci využít v každodenním pracovním životě.This diploma thesis focuses on social media usage in B2B sales. Based on the systematic literature review conducted by the author, he has found out that recent researchers (Salo, 2017) suggest further research in the area of how and in which sales phase should various social networking sites, technologies and plugins used. To further fill this research gap, author decided to identify these social media and their usage among B2B salespeople in the so-called social selling process. The social selling process in this thesis applies mainly to acquiring new prospects and tangentially to taking care of existing clients (follow-up step). Author has chosen a qualitative research method via conducting 10 in-depth semi-structured interviews to reveal these instruments as well as motivation of a sales person on why to use social media in the selling process. The collected data was analyzed using Thematic analysis to ensure the right procedure and to identify main themes which crystalized into 2 main strategic approaches in social selling. These approaches (Push and Pull) include practical examples of concrete activities which sales people can use in their daily jobs and are presented with focus on practicality and ease of implementation. These also form the main contribution of author`s research. In the last part, author mentions challenges in social selling and recommended managerial implications for salesforce
TeX v jednoduchém unixovém prostředí

V tomto článku je ukázáno, jak tuto práci dělá autor článku. Proces "editor-TeX-kuk" je zde podporován jednoduchými unixovými nástroji: bashovým skriptem texloop, který si autor pro tyto účely vytvořil, dále terminálem Xterm a jednoduchým editorem, který umí navázat na klávesovou zkratku spuštění příkazu v systému. Čtenář se zde může inspirovat a přizpůsobit tyto nástroje svým vlastním potřebám. V článku je popsána funkce skriptu texloop, dále je neformálně rozveden dlouholetý vývoj autorova vztahu k textovým editorům a konečně je zde uvedena konfigurace terminálu Xterm, aby vyhovoval českému prostředí jak v kódování ISO-8859-2, tak v kódování UTF-8. Pro kódování UTF-8 si v závěru článku vygenerujeme TeXový formát csplain.summary:By debugging a TeX document it is necessary many times repeatedly to run TeX, to look for the result in DVI or PDF file, to gander the TeX output on the terminal, or eventually to have a look in the log-file, and all that action to repeat. In the paper it is show, how this work is made by author. The process '‘'editor-TeX-look' is supported by simple Unix tools: bash script texloop, created by author for these purposes, Xterm terminal and a simple editor, which is able to link to the shortcut key the activation of a system command. The reader could be inspired with the solution and to adapt these tools to his/her own needs. In the paper the function of the texloop script is described, and further the longstanding evolution of the author's relation to text editors is informal elaborated and finally a configuration of Xterm terminal, suitable for the czech environment with both ISO-8859-2 and UTF-8 encoding is introduced. For UTF-8 encoding the TeX format csplain is generated at the end of the paper
