To 'be', and not to 'have': auxiliary selection in unaccusative verbs in Italian

This paper investigates the characteristics of unaccusative verbs in Italian with respect to the consistency with which these verbs select the auxiliaries ‘be’ (essere) and ‘have’ (avere) in compound tense forms. The study builds on the gradient approach to split intransitivity (Sorace 2000) by exploring the behaviour of 29 intransitive Italian verbs with respect to their core-peripheral features: auxiliary selection acceptability ratings and associated variance measures. Although there is clear support for the gradient approach in relation to the general order of semantic categories along the unaccusativity gradient, the results reveal that the ordering of subclasses within the Change group conflict with that currently proposed in the literature. In addition, the findings demonstrate the aspectual and lexical semantic characteristics of internally-caused change-of-state verbs in Italian require further investigation before their auxiliary selection behaviour can be properly understood. Furthermore, contrary to the gradient account, Existence verbs, the most stative and therefore the most peripheral subclass in the unaccusativity hierarchy, exhibit behaviour more characteristic of core unaccusative verbs. This study examines a wider range of semantic subclasses of unaccusative verbs than has hitherto been reported and identifies the core-peripheral boundary for Italian.1

How children's television networks in the United States have adapted to the changing digital habits of their young audiences: A comparative analysis between the Disney Channel and Nickelodeon

In the contemporary societies, many children are drawn to digital media, using it in ways that were initially unfathomable. Changing digital habits among young children have been affiliated to the rapid development, witnessed in the technological field. Prevalently, new forms of technology are being developed and ingrained into young children’s day-to-day activities. The emergence of new forms of technology has in turn prompted significant changes in digital and media consumption particularly, among young children. Changes in media and digital consumption have in turn instigated linear transition in the analogue media industries. This has resulted in analogue media networks working towards digitalizing their industries in a manner that will befit changing digital habits among young children. This report aims at establishing and analyzing the different ways in which children’s digital habits have changed and revolutionized. To achieve this, the report will critically examine the existing scope of knowledge, with reference to changing digital habits among young audiences. Further, the report also aims at establishing the manner in which children television networks have adapted to the changing digital habits among young audiences. To achieve this, the report will focus on two children television networks, Disney channel, and Nickelodeon. After which, a comparative analysis will be conducted to establish the changes made by each of these television channels, with the aim of adapting to the new digital habits among children.

Which strategies can an educational business, such as a kindergarten in Germany, develop to foster employee engagement?

Which strategies can an educational business, such as a Kindergarten in Germany, develop to foster employee engagement? The goal of this master thesis is to identify effective and viable measures to engage employees, that could be potentially implemented in a Kindergarten in Germany. The literature concerning the notion of employee engagement is so inconsistent that even studies about the subject fail to find one common definition and have to acknowledge the variety of existing definitions (IES, 2014, p.52-53). This reflects the youth of the concept, which has only been partially studied by academics and practitioners in recent years. The literature gap about employee engagement concerns many aspects, among which small companies and educational businesses, in particular those focusing on early child development. Considering the low levels of employee engagement in Germany combined with the absence of studies on educational organizations focusing in early child development this master thesis studies engagement in German Kindergärten(s). This master thesis is divided in two parts consisting of a literature review and a case study. The literature review allows to follow the evolution of the concept along the years, while the case study focuses on assessing employee engagement in Montessori Kindergärten(s) in Munich & elaborating potential measures to increase engagement levels. Double sided research was undertaken for this case study. On the one hand a quantitative research was performed, through a survey, in order to uncover which strategies would be viable to foster employee engagement. On the other hand a qualitative research was undertaken, consisting in an internship in a Kindergarten, in order to shed light on how to do so. Findings in the quantitative research indicate overall engagement levels average to low. Results related to specific statements bring out the originality of the educational sector, which is in some aspects intrinsically engaging, similarly to the medical field (Seijts & Crim, 2006). Furthermore low engagement levels led to a conversely high number of positives responses to potential engagement strategies suggesting their potential effectiveness. Findings in the qualitative research are coherent with qualitative results and complement them

Preparation and evaluation of an experimental luting glass ionomer cement to be used in dentistry

The aim of this paper is to compare the fluoride-releasing and mechanical properties of an experimental luting glass ionomer cement, which has a modified composition and a commercial luting cement. The experimental powder was obtained by sol-gel process and then, it was used to prepare the experimental cements. The properties of cement pastes, such as setting time and working time, microhardness and diametral tensile strength were determined. Fluoride release from GICs was evaluated at time intervals of 1, 7, 14, 21 and 28 days in deionized water. Atomic force microscopy (AFM) analyses showed that the surface of the experimental cements is more homogeneous than commercial GICs. The mechanical properties and the measure of liberation of fluoride of the two cements were influenced by ratio powder:liquid and chemical composition of the precursor powders. Experimental cements released less fluoride than commercial cements. However, this liberation was more constant during the analyzed period. Thus, the results obtained in this study indicated that the composition of the experimental powder modified by the niobium can lead the formation of the polysalt matrix with good mechanical properties. In other words, we can say that experimental powder offered considerable promise for exploitation in dental field.

Nanoparticles for efficient uptake by human dendritic cells and T lymphocytes to be used in adoptive immunotherapy

Dendritic cells (DCs) are the most potent cell type for capture, processing, and presentation of antigens. They are able to activate naïve T cells as well as to initiate memory T-cell immune responses. T lymphocytes are key elements in eliciting cellular immunity against bacteria and viruses as well as in the generation of anti-tumor and anti-leukemia immune responses. Because of their central position in the immunological network, specific manipulations of these cell types provide promising possibilities for novel immunotherapies. Nanoparticles (NP) that have just recently been investigated for use as carriers of drugs or imaging agents, are well suited for therapeutic applications in vitro and also in vivo since they can be addressed to cells with a high target specificity upon surface functionalization. As a first prerequisite, an efficient in vitro labeling of cells with NP has to be established. In this work we developed protocols allowing an effective loading of human monocyte-derived DCs and primary antigen-specific T cells with newly designed NP without affecting biological cell functions. Polystyrene NP that have been synthesized by the miniemulsion technique contained perylenmonoimide (PMI) as a fluorochrome, allowing the rapid determination of intracellular uptake by flow cytometry. To confirm intracellular localization, NP-loaded cells were analyzed by confocal laser scanning microscopy (cLSM) and transmission electron microscopy (TEM). Functional analyses of NP-loaded cells were performed by IFN-γ ELISPOT, 51Chromium-release, and 3H-thymidine proliferation assays. In the first part of this study, we observed strong labeling of DCs with amino-functionalized NP. Even after 8 days 95% of DCs had retained nanoparticles with a median fluorescence intensity of 67% compared to day 1. NP loading did not influence expression of cell surface molecules that are specific for mature DCs (mDCs) nor did it influence the immunostimulatory capacity of mDCs. This procedure did also not impair the capability of DCs for uptake, processing and presentation of viral antigens that has not been shown before for NP in DCs. In the second part of this work, the protocol was adapted to the very different conditions with T lymphocytes. We used leukemia-, tumor-, and allo-human leukocyte antigen (HLA) reactive CD8+ or CD4+ T cells as model systems. Our data showed that amino-functionalized NP were taken up very efficiently also by T lymphocytes, which usually had a lower capacity for NP incorporation compared to other cell types. In contrast to DCs, T cells released 70-90% of incorporated NP during the first 24 h, which points to the need to escape from intracellular uptake pathways before export to the outside can occur. Preliminary data with biodegradable nanocapsules (NC) revealed that encapsulated cargo molecules could, in principle, escape from the endolysosomal compartment after loading into T lymphocytes. T cell function was not influenced by NP load at low to intermediate concentrations of 25 to 150 μg/mL. Overall, our data suggest that NP and NC are promising tools for the delivery of drugs, antigens, and other molecules into DCs and T lymphocytes.

Capuchin Monkeys (Cebus apella) Fail to Be Equitable in an Ultimatum Game

The ultimatum game is a commonly used economics game testing humans' sense of fairness. In the game, a "proposer" is given a sum of money and is told they can split it however they want with another human partner. The partner can then either accept the division and both proposer and responder receive the proposed amounts, or the responder can reject the offer and neither player will get anything. Human subjects from most western cultures typically share almost half of an allotted amount, but it remains unknown whether our close primate relatives share this generosity. Recent attempts to present chimpanzees with the ultimatum game have provided inconclusive results, with some studies finding the animals share humans' disposition to behave 'fairly' and others concluding that chimpanzees act selfishly to maximize their own rewards. Capuchin monkeys are known to share many human and chimpanzee social and cooperative behaviors, and this study was the first to present capuchin monkeys with a version of the ultimatum game. Subjects were presented with two differently colored tokens representing different qualitative reward contingencies, one equitable and the other inequitable in favor of the subject proposer. Subjects could select and place one of the tokens in a transfer container. The capuchins were first tested with a "dictator game" where, after the subject monkey selected a token, the rewards (equitable or inequitable) were distributed to the subject and a nearby partner monkey that was not an active participant. The capuchins were then tested on an ultimatum game in which after the subject selected and placed a token in the container, the container was moved to the partner. The partner needed to remove the token and transfer it back to the experimenter for the rewards to be distributed. As such, the partner could reject the subject's offer by refusing to participate and neither would receive a reward. The experiment was conducted to determine if the subject monkey would select the equitable reward option rather than the selfish option in order to maintain the partner's cooperation in the task. Capuchin subjects behaved selfishly and selected the inequitable token significantly more often than the equitable token in both the dictator and ultimatum game with no significant difference in preference between the two games. Interestingly, despite the occasional occurrence of rejection by the partner monkeys (resulting in no reward for the subject), subjects never altered their strategy, continuing to prefer the selfish token. The study may indicate that capuchin monkeys have an inability to judge the effect of their behavior on a conspecific's reward outcome, or an indifference to the outcome if there is an individual cost associated with behaving prosocially.

What is to be done with surplus embryos? Attitude formation with ambivalence in German fertility patients

Improved pregnancy rates in IVF have led to increasing numbers of surplus embryos which can potentially be used for purposes like donation to another infertile couple or further research. Individuals report high levels of ambivalence concerning the donation of surplus embryos. This study examined which strategies infertile patients use to deal with this ambivalence when asked to evaluate potential dispositions of surplus embryos created during IVF. Guideline-based interviews with fertility patients were audio-recorded and transcribed verbatim. Following the principle of theoretical sampling, eight interviews were analysed by use of Grounded Theory. Analyses focused on processes of individual attitude formation. Strategies for handling ambivalence during attitude formation were identified: the six strategies comprise cognitive and communicative strategies, and were integrated into a model of attitude formation under ambivalence. As ambivalence is a relevant phenomenon in attitude formation within IVF treatment, assessment of ambivalence is strongly recommended in social science studies investigating ethical problems in patient care. In the context of informed consent, there is a need for individual counselling which draws attention to the conflicting values during attitude formation. Counsellors should be aware of the signs of and the strategies to deal with ambivalence.

Which Radiographic Hip Parameters Do Not Have to Be Corrected for Pelvic Rotation and Tilt?

Background Acetabular anatomy on AP pelvic radiographsdepends on pelvic orientation during radiograph acquisition. However, not all parameters may change to a clinically relevant degree with differences in pelvic orientation. This issue may influence the diagnosis of acetabular pathologies and planning of corrective acetabular surgery (reorientation or rim trimming). However, to this point, it has not been well characterized. Questions/purposes We asked (1) which radiographic parameters change in a clinical setting when normalized to neutral pelvic orientation; (2) which parameters do not change in an experimental setting when the pelvis is experimentally rotated/tilted; and (3) which of these changes are ‘‘ultimately’’ relevant based on a prespecified definition of relevance. Methods In a clinical setup, 11 hip parameters were evaluated in 101 patients (126 hips) by two observers and the interobserver difference was calculated. All parameters were normalized to an anatomically defined neutral pelvic orientation with the help of a lateral pelvic radiograph and specific software. Differences between nonnormalized and normalized values were calculated (effect of normalization). In an experimental setup involving 20 cadaver pelves (40 hips), the maximum range for each parameter was computed with the pelvis rotated (range, −12° to 12°) and tilted (range, −24° to 24°). ‘‘Ultimately’’ relevant changes existed if the effect of normalization exceeded the interobserver difference (eg, 37% versus 6% for prevalence of a positive crossover sign) and/or the maximum experimental range exceeded 1 SD of interobserver difference (eg, 27% versus 6% for anterior acetabular coverage). Results In the clinical setup, all parameters except the ACM angle and craniocaudal acetabular coverage changed when being normalized, eg, effect of normalization for lateral center-edge angle, acetabular index, and sharp angle ranged from −5° to 4° (p values < 0.029). In the experimental setup, five parameters showed no major changes, whereas six parameters did change (all p values < 0.001). Ultimately relevant changes were found for anteroposterior acetabular coverage, retroversion index, and prevalence of a positive crossover or posterior wall sign. Conclusions Lateral center-edge angle, ACM angle, Sharp angle, acetabular and extrusion index, and craniocaudal acetabular coverage showed no relevant changes with varying pelvic orientation and can therefore be acquired independent from individual pelvic tilt and rotation in clinical practice. In contrast, anteroposterior acetabular coverage, crossover and posterior wall sign, and retroversion index call for specific efforts that address individual pelvic orientation such as computer-assisted evaluation of radiographs.

Colonization with resistant microorganisms in patients transferred from abroad: who needs to be screened?

BACKGROUND While multi-drug resistant organisms (MDRO) are a global phenomenon, there are significant regional differences in terms of prevalence. Traveling to countries with a high MDRO prevalence increases the risk of acquiring such an organism. In this study we determined risk factors for MDRO colonization among patients who returned from a healthcare system in a high-prevalence area (so-called transfer patients). Factors predicting colonization could serve as screening criteria to better target those at highest risk. METHODS This screening study included adult patients who had been exposed to a healthcare system abroad or in a high-prevalence region in Switzerland over the past six months and presented to our 950-bed tertiary care hospital between January 1, 2012 and December 31, 2013, a 24-month period. Laboratory screening tests focused on Gram-negative MDROs and methicillin-resistant Staphylococcus aureus (MRSA). RESULTS A total of 235 transfer patients were screened and analyzed, of which 43 (18 %) were positive for an MDRO. Most of them yielded Gram-negative bacteria (42; 98 %), with only a single screening revealing MRSA (2 %); three screenings showed a combination of Gram-negative bacteria and MRSA. For the risk factor analysis we focused on the 42 Gram-negative MDROs. Most of them were ESBL-producing Escherichia coli and Klebsiella pneumoniae while only two were carbapenemase producers. In univariate analysis, factors associated with screening positivity were hospitalization outside of Europe (p < 0.001), surgical procedure in a hospital abroad (p = 0.007), and - on admission to our hospital - active infection (p = 0.002), antibiotic treatment (p = 0.014) and presence of skin lesions (p = 0.001). Only hospitalization outside of Europe (Odds Ratio, OR 3.2 (95 % CI 1.5- 6.8)) and active infection on admission (OR 2.7 (95 % CI 1.07- 6.6)) remained as independent predictors of Gram-negative MDRO colonization. CONCLUSION Our data suggest that a large proportion of patients (i.e., 82 %) transferred to Switzerland from hospitals in high MDRO prevalence areas are unnecessarily screened for MDRO colonization. Basing our screening strategy on certain criteria (such as presence of skin lesions, active infection, antibiotic treatment, history of a surgical procedure abroad and hospitalization outside of Europe) promises to be a better targeted and more cost-effective strategy.

How to be in a good shape? The influence of clone morphology on cell competition

Cell competition is a conserved mechanism where slow proliferating cells (so called losers) are eliminated by faster proliferating neighbors (so called winners) through apoptosis.(1) It is an important process which prevents developmental malformations and maintains tissue fitness in aging adults.(2) Recently, we have shown that the probability of elimination of loser cells correlates with the surface of contact between losers and winners in Myc-induced competition.(3) Moreover, we have characterized an active mechanism that increases the surface of contact between losers and winners, hence accelerating the elimination of loser cells. This is the first indication that cell shape and mechanics can influence cell competition. Here, we will discuss the consequence of the relationship between shape and competition, as well as the relevance of this model for other modes of competition.

Fine mapping of colon tumor susceptibility (Scc) genes in the mouse, different from the genes known to be somatically mutated in colon cancer.

The predisposition to colon cancer is multigenetically controlled in animals and probably also in humans. We have analyzed the multigenic control of susceptibility to 1,2-dimethylhydrazine-induced colon tumors in mice by using a set of 20 homozygous CcS/Dem recombinant congenic strains, each of which contains a different random subset of approximately 12.5% of genes from the susceptible strain STS/A and 87.5% of genes from the relatively resistant strain BALB/cHeA. Some CcS/Dem strains received the alleles from the susceptible strain STS/A at one or more of the multiple colon tumor susceptibility loci and are susceptible, whereas others are resistant. Linkage analysis shows that these susceptibility genes are different from the mouse homologs of the genes known to be somatically mutated in human colon cancer (KRAS2, TP53, DCC, MCC, APC, MSH2, and probably also MLH1). Different subsets of genes control tumor numbers and size. Two colon cancer susceptibility genes, Scc1 and Scc2, map to mouse chromosome 2. The Scc1 locus has been mapped to a narrow region of 2.4 centimorgans (90% confidence interval).

Detailing for a research centre in Antarctica: An experiment to force students to be creative instead of copying standard solutions

In order to equip architecture students with ambitious detail designing ability, related courses of the architecture programs should deal with subjects which are rather rare and unusual for real life practices in order to prevent students copying standard details. In 2015 an innovative project brief has been given to architecture students of Istanbul Technical University. The scenario given in the brief is to design a research station for the first group of Turkish scientist, to be built in one of the coldest and most arid regions on earth; the Antarctica. The performance requirements given in the brief were determined to prevent the students from copying details from any kind of resources as the total number of details generated in real life for those conditions are very limited and specific. The method used has demonstrated a great success and creative detail solutions were generated by the students. In the paper, the innovative coursework brief for bettering the detail design ability of architecture students is explained and the output of the studio is presented.
