Extending Signaling Theory to Rhetorical Signals: Evidence from Crowdfunding
Authors: Steigenberger Norbert , Wilhelm Hendrik 
Published: May 2018

Firms often need to acquire external financial resources to maintain and develop their business. To attract these resources, firms employ various substantive and rhetorical signals, such as publishing press releases, showcasing prototypes of new products, and hiring renowned managers. However, despite the relevance of signals, we still know little about how they interact—whether they strengthen, weaken, or neutralize one another—in attracting resources. Traditional signaling theory downplays the importance of rhetoric while management research acknowledges its relevance, creating a disconnect between these two camps and a shortcoming that deserves further investigation. To address this shortcoming, we advance the concept of signal portfolios. Signal portfolios may combine rhetorical signals with substantive signals. We employ this concept to explain how the interaction of the two affects financial resource acquisition in high-noise environments—settings where firms send multiple signals simultaneously. Based on longitudinal data on crowdfunding, an exemplary high-noise environment, we find that rhetorical signals complement substantive signals in certain situations and, thus, strengthen their impact on a firm’s financial resource acquisition. Contrary to our expectations, however, we find that under specific conditions, rhetorical signals may also weaken the impact of substantive signals. Our research has implications for signaling theory, crowdfunding research, and management practice. The online appendix is available at https://doi.org/10.1287/orsc.2017.1195 .

Published: May 2018

Background: The majority of Kenya's population lives in rural areas with limited access to higher education. A blended ‘eBSc Nursing’ programme was created to bridge the gap. Aims: To explore users' views on the effectiveness of the pilot blended e-learning BSc Nursing programme in Kenya. Methods: A mixed methods approach was used in data collection. All students in the pilot eBsc Nursing programme were sampled and focus group discussions were held with lecturers and mentors. Findings: The majority of the pilot cohort (84%) were satisfied with the quality of training and the inherent flexibility of the model. Offline e-learning sites were only accessible to 64% of learners. Limited ICT skills among lecturers were a concern to 46% of the respondents. Trainers were of the opinion that the in-service eLearners either performed at equal to or better than conventionally-trained BscN students. Conclusions: There was a positive user response to the eBscN upgrading programme. Learner support systems required more strengthening to deliver on desired objectives.
The root diagram for one-point AG codes arising from certain curves with separated variables
Authors: Fornasiero Federico , Tizziotti Guilherme 
Published: May 2018

Heegard, Little and Saints introduced in [8] an encoding algorithm for a class of AG codes via Gröbner
basis more compact compared with the usual encoding via generator matrix. So, knowing that the
main drawback of Gröbner basis is the high computational cost required for its calculation, in [12],
the same authors introduced the concept of root diagram that allows the construction of an algorithm
for computing a Gröbner basis with a lower complexity for one-point Hermitian codes. In [4], Farrán,
Munuera, Tizziotti and Torres extended the results obtained in [12] for codes on norm-trace curves.
In this work we generalize these results by constructing the root diagram for codes arising from certain
curves with separated variables that has certain special automorphism and a Weierstrass semigroup
generated by two elements. Such family of curves includes the norm-trace curve, among other curves
with recent applications in coding theory.
Teachers as role models in the political socialization process: How a good student–teacher relationship can compensate for gender differences in students’ gender equality attitudes
Authors: Sampermans Dorien , Claes Ellen 
Published: May 2018

Abstract
The social justice teaching theory describes how teachers can transfer equality attitudes to their students. According to this theory, teachers are important role models in the political socialization process. Starting from an unequal disposition of equality attitudes between boys and girls, this article analyses how teachers can bring equality to the classroom by compensating for different attitudes on the topic of gender equality. We first discuss how teachers can influence equality attitudes, comparable to the influence by parents’ socialization. Second, we assess whether teachers can compensate for differences in equality attitudes. Parallel to the evidence from studies on parental socialization, we expect teachers with better student–teacher relationships in particular to be able to transfer equality attitudes better. For the analyses, we use the International Civic and Citizenship Education Study (ICCS), an important study of 14-year-olds’ civic knowledge, attitudes and engagement. We use data from seven European countries and the Greek part of Cyprus (1160 schools and 24,087 students). To take the multilevel structure of this data into account, the analysis included a multilevel analysis (MLwiN). As expected we found a positive association between student–teacher relationships and equality attitudes. We also find that a good student–teacher relationship can compensate for attitudinal differences. By assessing adolescents’ equality attitudes, we conclude that teachers can close an attitudinal gender gap.
Civic literacy through literacy instruction: Using Structured Academic Controversy in a government classroom
Authors: Lo Jane C. , Adams Carol I. 
Published: May 2018

Abstract
We present how working with text in the classroom can promote civic literacy aims by adapting and studying a well-known instructional method in Social Studies classrooms called Structured Academic Controversy (SAC). Not only do SACs give students an opportunity to engage in this form of deliberation, it also requires students to first become well informed on the topic (an important aspect of civic literacy) through close reading of text. Such text-based discussion is even more important in promoting comprehension when the texts are dense and complex (e.g. the US Constitution, SCOTUS decisions). In this paper, we propose that to obtain civic literacy, students need to gain a deeper understanding of crucial civic knowledge and information through texts and to evaluate how the information might best serve a democratic society.
Empedocles’ Emulation of Anaxagoras and Pythagoras (D.L. 8. 56)
Authors: Panchenko Dmitri 
Published: May 2018

Abstract
Diogenes Laertius cites Alcidamas for the statement that Empedocles emulated Anaxagoras and Pythagoras in his dignity of bearing and the philosophy of nature. Contrary to the standard view, I shall argue that Alcidamas made Empedocles imitate Anaxagoras in his manners and Pythagoras in his teaching.
Philosopher in the market square: Probing the statement ‘I was misled’
Authors: Olatunji Cyril-Mary Pius , Koenane Mojalefa L. J. 
Published: May 2018

Abstract
Traditionally, such a statement as ‘I was misled’ is intended to be taken seriously by the addressee and considered an expression of the true state of affairs. Unfortunately, the statement has many logical implications that often go unnoticed by both the one who utters it and the addressee. The paper critically explores the instrumentality of logical and epistemological analyses in its attempt to lay bare the implications of the statement being true and of entertaining the underlying belief in the first place that ‘I was misled’. By so doing, the paper attempts to show that even if the function of philosophy is merely to analyse language, it would still have contributed indispensably and significantly to human society by clarifying ambiguous concepts. It also attempts to demonstrate the relevance of critical thinking in human society.
Exploring new types of intensive motherhood in the Czech Republic
Authors: Marková Volejníčková Romana 
Published: May 2018

Abstract
Intensive motherhood (IM) has become an established social norm in many countries, especially Western ones. Centred upon the mother providing lengthy full-time, intensive care focused on the child’s needs, these social norms can be seen in the actions of mothers in diverse social locations. However, recent research has demonstrated that women’s ability to engage in IM is affected by factors like education, race, ethnicity, religion or socioeconomic status as well as by cultural and structural conditions. The goal of this paper is to analyse IM in the Czech context by focusing on factors that most affect a mother’s ability to engage in IM. Biographical interviews were held with 17 mothers, and the following three areas were discussed most in their narratives: (a) use of information on childrearing, (b) attitude to paid employment and juggling family and work, and (c) the financial, mental and emotional costs of motherhood.

Published: May 2018

Abstract
Informational capabilities of microwave and optical tools for environmental monitoring are assessed when they are located on the mobile platforms. This paper presents new approach to the combined use of microwave and optical sensors as basic elements of environmental monitoring system architecture oriented on the registration of information about characteristics of hydrological and hydrochemical objects. Geoecological in-formation-modeling system (GIMS) is proposed as the GIS generalization with regard to the solution of series of the tasks arising in the agriculture, water quality assessment and operational diagnostics of stressful natural processes. Algorithms and models are characterized to be as the GIMS components that realize the decision making procedures providing the monitoring regime optimization and reconstruction of spatial image of the controlled environmental object using anisotropic data fluxes. Functional characteristics of several mobile platforms equipped by microwave radiometers are given as tools for the monitoring of hydrological objects. Two optical instruments are represented and their functions are characterized.
TRANSIENT STATE CHARACTERIZATION OF ASYNCHRONOUS MOTORS IN MODERN LOW-VOLTAGE ELECTRIC INSTALLATIONS
Authors: Cazacu Emil , Ioniţă Valentin , Petrescu Lucian 
Published: May 2018

Abstract
: Low-voltage asynchronous motor is the most common load used in any industrial electric facility. Due to their robustness and reliability, the induction motors have a very large application spectrum and are to be found in a variety of power units. It is assumed that over 70% of total energy used in any electric utility is dedicated to the electric motor drive systems. The paper quantitatively studies the transient state of such motors, which occurs at their start-up. The waveforms characteristics of these inrush currents are predetermined mainly by solving the associated differential equations that describe the dynamic phenomena at their start-up. An experimental investigation on an induction motor of 4 kW is also carried out. Supplementary, different solutions for the energising of these low-voltage motors are presented highlighting their performances and limits. These methods are critically rated according to their mitigation ability of the power quality issues associated with the energizing process.

Authors: Georgescu Madalina , Budu V. , Vrinceanu Daniela , Cernea Magdalena 
Published: May 2018

Abstract
For individuals with conductive or mixed hearing loss, a bone conduction system can be a very effective treatment option. These systems bypass the outer and middle ear to send sound vibrations directly to the cochlea. This offers a natural sound quality for recipients. BONEBRIDGE is the first active, intact skin hearing implant for bone conduction stimulation, ideal for moderate to severe conduction hearing losses. It is a semi-implantable system, consisting of a surgical implantable part and an externally worn audio processor. Biomaterials used proved their safety, with very low rate of medical complications (skin infections, chronic suppurative otitis media, biofilm formation or extrusion).

ETHNIC PARTIES:DEFINITION AND CLASSIFICATION
Authors: Berat David 
Published: May 2018

Abstract
The article is about defining ethnic parties and their classification. We define and discuss the terms politics, political party, ethnis group and ethnical party. We state differences about the traditional model of politics and the modern one. We analyze the importance of the political parties in representing the political rights of the people and what is needed so a political party can be established in the Republic of Macedonia. Also we show how to determine which party is an ethnical party and show a number of ethnic parties in Republic of Macedonia using the name of the party as an indicator. In this part we discuss the indicators and we state that good indicator is the program of the election campaign of the party. But still this is not 100% sure indicator if the party is ethnical. We concluded this because there are a lot of examples when the ruling party before the start of the election campaign does a research about the ethnical groups and after the research makes projects meant for the ethnic groups so the party can get the votes from the chosen ethnicity. At the end we concluded that the programs and the statues of the political parties are the best indicators and answer if a political party is a non-ethnical, multi-ethnical or ethnical political party.

Mortality in acromegaly decreased in the last decade: a systematic review and meta-analysis
Authors: Bolfi F , Neves A F , Boguszewski C L , Nunes-Nogueira V S 
Published: May 2018

ObjectiveTo compare the acromegaly mortality rates with those expected for the general population from studies published before and after 2008.MethodsWe performed a systematic review and included observational studies in which the number of deaths observed in acromegaly was compared with the expected mortality for the general population mortality observed/expected (O/E). The following electronic databases were used as our data sources: EMBASE, MEDLINE and LILACS. From the observed and expected deaths, we recalculated all standardized mortality ratios (SMR) and their respective confidence intervals (95% CI), which were plotted in a meta-analysis using the software RevMan 5.3.ResultsWe identified 2303 references, and 26 studies fulfilled our eligibility criteria. From the 17 studies published before 2008, the mortality in acromegaly was increased, while from the nine studies published after 2008, the mortality was not different from the general population (SMR: 1.35, CI: 0.99–1.85). In six studies where somatostatin analogs (SAs) were used as adjuvant treatment, acromegaly mortality was not increased (SMR: 0.98, CI: 0.83–1.15), whereas in series including only patients treated with surgery and/or radiotherapy, mortality was significantly higher (SMR: 2.11; CI: 1.54–2.91). In studies published before and after 2008, the mortality was not increased in patients who achieved biochemical control, while it was higher in those with active disease. Cancer has become a leader cause of deaths in acromegaly patients in the last decade, period in which life expectancy improved.ConclusionMortality in acromegaly is normalized with biochemical control and decreased in the last decade with the more frequent use of SAs as adjuvant therapy. Increased life expectancy has been associated with more deaths due to cancer.
A Genomic Region Containing REC8 and RNF212B Is Associated with Individual Recombination Rate Variation in a Wild Population of Red Deer (Cervus elaphus)
Authors: Johnston Susan E , Huisman Jisca , Pemberton Josephine M 
Published: May 2018

Abstract
Recombination is a fundamental feature of sexual reproduction, ensuring proper disjunction, preventing mutation accumulation and generating new allelic combinations upon which selection can act. However it is also mutagenic, and breaks up favorable allelic combinations previously built up by selection. Identifying the genetic drivers of recombination rate variation is a key step in understanding the causes and consequences of this variation, how loci associated with recombination are evolving and how they affect the potential of a population to respond to selection. However, to date, few studies have examined the genetic architecture of recombination rate variation in natural populations. Here, we use pedigree data from ∼ 2,600 individuals genotyped at ∼ 38,000 SNPs to investigate the genetic architecture of individual autosomal recombination rate in a wild population of red deer (Cervus elaphus). Female red deer exhibited a higher mean and phenotypic variance in autosomal crossover counts (ACC). Animal models fitting genomic relatedness matrices showed that ACC was heritable in females (h2 = 0.12) but not in males. A regional heritability mapping approach showed that almost all heritable variation in female ACC was explained by a genomic region on deer linkage group 12 containing the candidate loci REC8 and RNF212B, with an additional region on linkage group 32 containing TOP2B approaching genome-wide significance. The REC8/RNF212B region and its paralogue RNF212 have been associated with recombination in cattle, mice, humans and sheep. Our findings suggest that mammalian recombination rates have a relatively conserved genetic architecture in both domesticated and wild systems, and provide a foundation for understanding the association between recombination loci and individual fitness within this population.
