Abstract
There are many known examples of scalar-flat
Kähler ALE surfaces, all of which have
group at infinity either cyclic or contained in

SU

(

{{\rm{SU}}(2)}

.
The main result in this paper shows that for any non-cyclic finite subgroup
Γ

⊂

\subset

U(2) containing no complex reflections, there exist
scalar-flat Kähler ALE metrics on the minimal
resolution of

\mathbb{C}^{2}

/Γ, for which Γ occurs as the
group at infinity. Furthermore, we show that these metrics admit a holomorphic isometric circle action.
It is also shown that there exist scalar-flat Kähler ALE
metrics with respect to some small deformations of complex structure
of the minimal resolution. Lastly, we show the existence of
extremal Kähler metrics admitting holomorphic isometric circle actions
in certain Kähler classes on the complex analytic
compactifications of the minimal resolutions.
Soziale Bewegungen bleiben ein bedeutender politischer Faktor
Authors: Klein Ansgar 
Published: June 2016

Zusammenfassung
In Auseinandersetzung mit gängigen Argumenten über das Ende der neuen sozialen Bewegungen bin ich auf deren Zukunftschancen eingegangen. Ich habe argumentiert, dass es zwar zu einem Formwandel (insbesondere zu einem Bedeutungsanstieg spezialisierter Bewegungsorganisationen und NGOs) kommen wird, dass jedoch die links-libertären Bewegungen in den westlichen Demokratien auch weiterhin eine wichtige Rolle spielen werden. Die Themenstellungen der neuen sozialen Bewegungen sind keineswegs integriert und ‚erledigt‘, sondern bleiben von großer Relevanz. Entlang absehbarer neuer Konfliktlinien (Inklusion/Exklusion) halte ich die Chancen für rechte soziale Bewegungen oder aber populistische Politikformen im Zusammenspiel mit sozialen Bewegungen für groß. Daher ist von einem polarisierten Bewegungssektor und einer verschärften Dramatik von Bewegungen und Gegenbewegungen auszugehen. Die europäische und die internationale Arena werden als Bühne transnational vernetzter Bewegungen eine immer wichtigere Rolle spielen, die damit auf das Gewicht globaler Problemstellungen reagieren. In den Ländern des Südens und Ostens werden soziale Bewegungen in einer großen Vielfalt entstehen (von fundamentalistischen und ethnischen bis zu Bürgerbewegungen und links-libertären Bewegungen), und hier sind Formen des Massenprotestes wahrscheinlicher als in den westlichen Demokratien. Auch wenn die Bewegungen im Süden und Osten sich nicht ohne weiteres mit den westlichen sozialen Bewegungen gleichsetzen lassen, so kommt es doch zu transnationalen Bewegungskoalitionen entlang der Achse von Globalisierungsgewinnern und - Verlierern.
Higher order nonlinear dynamic systems on time scales
Authors: Günendi Mustafa , Yaslan İsmail 
Published: June 2016

Abstract
In this paper, we consider a nonlinear system of higher order three-point boundary value problems on time scales. The Schauder fixed point theorem is used to investigate the existence of solutions of nonlinear dynamic systems on time scales. Furthermore, we establish the criteria for the existence of at least one, two and three positive solutions for higher order nonlinear dynamic systems on time scales by using the four functionals fixed point theorem, the Avery–Henderson fixed point theorem and the five functionals fixed point theorem, respectively.
Bicritical domination and double coalescence of graphs
Authors: Krzywkowski Marcin , Mojdeh Doost Ali 
Published: June 2016

Abstract
A graph is bicritical if the removal of any pair of vertices decreases the domination number. We study the properties of bicritical graphs and their relation with critical graphs, and we obtain results for bicritical graphs with edge connectivity two or three. We also generalize the notion of the coalescence of two graphs and investigate the bicriticality of such graphs.
Behavioural changes induced by a conditional disruption of bone formation
Authors: Zimmer Andreas , Otte David-Marian , Bilkei-Gorzo Andras , Armin Samar Muhammad , Bab Itai 
Published: June 2016

Abstract

Background: It has been shown that the brain regulates bone remodelling through sympathetic and parasympathetic nerve fibres. However, it is unclear if signals from the skeleton also influence brain functions and animal behaviours.

Methods: Bone formation was conditionally disrupted by daily injections of aciclovir (10 mg/kg) to transgenic mice expressing a herpes-simplex-virus thymidine kinase under the control of the osteoblast-specific promoter of the Bglap gene. Behavioural studies were conducted after 10 weeks of treatment.

Results: Transgenic mice receiving aciclovir injections showed a reduced number of osteoblasts with a concomitantly reduced trabecular bone volume density, when compared to wild-type controls that were treated identically. The general health of the animals was not severely affected, as indicated by a similar increase in body weight, similar activity profiles and similar social behaviours. However, transgenic mice showed significantly increased despair behaviour and increased adrenal gland weights.

Conclusions: Specific animal behaviours can be modulated by a selective disruption of bone formation. The increased despair behaviour observed in transgenic animals indicates that these animals may be more prone to depression-related phenotypes. These findings are important in the context of the well-established clinical association between depression and reduced bone mass.
Employee involvement in hotel total quality management
Authors: Maldonado Alcudia Ana Virginia del Carmen , Maldonado Alcudia Cesar Miguel , Maldonado Alcudia Minerva Candelaria 
Published: June 2016

Abstract
The paper focuses on the analysis of the employees’ behaviour, specifically in their involvement and commitment in hotel service after the implementation of a quality management system. When organization fails to involve the employees in a meaningful way, two types of workers could be identified; employees with high efficiency and employees with resistance to change. In this qualitative study, it was observed that if an employee doesn’t feel a sense of accomplishment, even when he constantly receives training courses, has incentives or sanctions, it is going to be difficult to get his involvement and commitment with the organization goals. This situation happens because the hotel quality management system is supported by an isomorphism with standardized rules that proceeded or originate from a different context and, in that system the features of the company and workers were not considered. The case study war carried out in a touristic destiny of sun-beach tourism in Mexico. Questionnaires and semi-structured interviews were prepared to elicit the employees’ participation in decision-making process, the employees’ involvement and commitment to achieve organization’s quality objectives, the employees’ efficiency in production processes and service, and the socialization. As already stated earlier, the intention of this paper is to develop an understanding of the actual practices that guide the relationships of human resources, when quality is joined as a contingent element.
The cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) as a new menace to cotton in Egypt and its chemical control

Published: June 2016

Abstract
The cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is a polyphagous sap sucking insect with a wide geographical and host range causing severe losses in economically important crops. This study represents the first record of P. solenopsis as a new insect attacking cotton plants (Gossypium barbadense var. Giza 86) in Kafr El-Sheikh governorate, Egypt. The insect was noticed on cotton plants for the first time during its growing season of 2014. The mealybug specimens were collected from infested cotton plants and identified as P. solenopsis. In an attempt to control this pest, eight toxic materials viz., imidacloprid, thiamethoxam, flonicamid, emamectin-benzoate, chlorpyrifos, methomyl, deltamethrin and mineral oil (KZ-oil), belonging to different chemical groups, were tested for their influence against P. solenopsis on cotton under field conditions. Methomyl, imidacloprid, thiamethoxam and chlorpyrifos showed the highest efficacy against P. solenopsis recording 92.3 to 80.4% reduction of the insect population. Flonicamid, emamectin-benzoate and KZ-oil failed to exhibit sufficient P. solenopsis control.
Co-occurrence of pathogenic and non-pathogenic Fusarium decemcellulare and Lasiodiplodia theobromae isolates in cushion galls disease of cacao (Theobroma cacao L.)
Authors: Castillo Daynet Sosa del , Parra Dercy , Noceda Carlos , Pérez-Martínez Simón 
Published: June 2016

AbstractFlowery cushion gall of cacao is a disease complex with six types. Fusarium decemcellulare have been isolated from both flowery and green point galls and recognized as the etiological agent of the disease. In the present work we: i) identified by ITS-rDNA sequencing and/or taxonomy the cultivable fungal species or Operative Taxonomic Units (OTUs) associated with the five symptoms of cushion galls in cacao from Venezuela, and ii) determined the gall inducing capacity on cacao peeled seeds after 45 days of inoculation with suspensions of mycelia/ spores from distinct isolate types. The whole isolate collection rendered an abundance of 113 isolates with a richness of 39 OTUs (27) and eight identified at the species or genera levels, respectively, and in unidentified fungi. The dominant recovered species (≈36%) were F. decemcellulare and Lasiodiplodia theobromae. Some isolates of F. decemcellulare, L. theobromae, F. equiseti, Fusarium spp., F. solani, F. incarnatum, Rhizocthonia solani and Penicillium sp. were pathogenic. Some other isolates of the first six mentioned taxa behave as non-pathogenic. Furthermore, pathogenic and non-pathogenic isolates can also co-occur within a single plant and gall type. Moreover, 2-5 species within a single gall symptom in a single tree were identified (not necessarily at the same point in the tree), indicating a broad diversity of co-occurring taxa.

Cell-Type-Selective Effects of Intramembrane Cavitation as a Unifying Theoretical Framework for Ultrasonic Neuromodulation
Authors: Plaksin Michael , Kimmel Eitan , Shoham Shy 
Published: June 2016

AbstractDiverse translational and research applications could benefit from the noninvasive ability to reversibly modulate (excite or suppress) CNS activity using ultrasound pulses, however, without clarifying the underlying mechanism, advanced design-based ultrasonic neuromodulation remains elusive. Recently, intramembrane cavitation within the bilayer membrane was proposed to underlie both the biomechanics and the biophysics of acoustic bio-effects, potentially explaining cortical stimulation results through a neuronal intramembrane cavitation excitation (NICE) model. Here, NICE theory is shown to provide a detailed predictive explanation for the ability of ultrasonic (US) pulses to also suppress neural circuits through cell-type-selective mechanisms: according to the predicted mechanism T-type calcium channels boost charge accumulation between short US pulses selectively in low threshold spiking interneurons, promoting net cortical network inhibition. The theoretical results fit and clarify a wide array of earlier empirical observations in both the cortex and thalamus regarding the dependence of ultrasonic neuromodulation outcomes (excitation-suppression) on stimulation and network parameters. These results further support a unifying hypothesis for ultrasonic neuromodulation, highlighting the potential of advanced waveform design for obtaining cell-type-selective network control.
Sociology and Methodology of Historical Research. Ethnomethodology
Authors: Konarska-Zimnicka Sylwia 
Published: June 2016

The article is taking issues of the social science methodology (with particular reference to sociology, with ethnomethodology at the head) in the context of the historical research methodology. Each of the social sciences developed its own methodology that is appropriate, according to the taken research problems. However, the dialogue between these special sciences turns out to be necessary, because people are making interpretations of sources that are staying in a specific place and time and various circumstances that are accompanying them. It is probably similar to the time when those sources arose. Thus, the analysis of the source material, irrespectively to its date of coming into existence, that it would be reliable must run at various levels, including the methodology and achievements of the so-called social sciences, amongst which, from a point of view of the historian, sociology will be playing a significant role. However, ethnomethodology, which is inspecting mechanisms “making reality shared”, offers to historians a wide range of research methods, which can expand the methodology of historical research.
Marginalization of South Asians Based on Race and Skin Color in Bharati Mukherjee’s Jasmine and Chitra B. Divakaruni’s “The Mistress of Spices”
Authors: Filipczak Iwona 
Published: June 2016

The purpose of this article is to focus on the issue of marginalization of South Asians in the United States as portrayed in two novels written by writers of Indian origin: Bharati Mukherjee’s Jasmine and Chitra Bannerjee Divakaruni’s The Mistress of Spices. It is investigated how race or skin color are the reasons for the marginalization of Indian immigrants in the United States. While Jasmine shows white Americans’ inability to embrace the racial difference of an Indian immigrant, which may be read as a reflection of the relative newness of this ethnic group in the United States and its shifting racial classification, The Mistress of Spices shows that the patterns of marginalization based on skin color may be developed already in the homeland, India, and then transferred to the US and confronted with the country’s racial diversity. Divakaruni’s novel raises a discussion of how the appreciation of whiteness developed in the country of birth leads to the hierarchical relations between the members of the Indian diaspora, and how it affects their relations with other American minorities. In this way, it shows that marginalization based on skin color is not only the outcome of inter-ethnic encounters but it can be an internal problem of this ethnic group as well.

Published: June 2016

BACKGROUND AND OBJECTIVE:
The hospital-to-hospital transfer of pediatric patients is a common practice that is poorly understood. To better understand this practice, we examined a national database to profile pediatric interfacility transfers.

METHODS:
We used the 2012 Kids’ Inpatient Database to examine characteristics of hospitalized pediatric patients (&lt;21 years; excluding pregnancy diagnoses) with a transfer admission source. We performed descriptive statistics to compare patient characteristics, utilization, and hospital characteristics between those admitted by transfer versus routine admission. We constructed a multivariable logistic regression model to identify patient characteristics associated with being admitted by transfer versus routine admission.

RESULTS:
Of the 5.95 million nonpregnancy hospitalizations in the United States in 2012, 4.4% were admitted by transfer from another hospital. Excluding neonatal hospitalizations, this rate increased to 9.4% of the 2.10 million nonneonatal, nonpregnancy hospitalizations. Eighty-six percent of transfers were to urban teaching hospitals. The most common transfer diagnoses to all hospitals nationally were mood disorder (8.9%), other perinatal conditions (8.7%), prematurity (4.8%), asthma (4.2%), and bronchiolitis (3.8%). In adjusted analysis, factors associated with higher odds of being admitted by transfer included having a neonatal principal diagnosis, male gender, white race, nonprivate insurance, rural residence, higher illness severity, and weekend admission.

CONCLUSIONS:
Interfacility transfers are relatively common among hospitalized pediatric patients. Higher odds of admission by transfer are associated not only with higher illness severity but also with principal diagnosis, insurance status, and race. Further studies are needed to identify the etiologies and clinical impacts of identified transfer differences.

Published: June 2016

OBJECTIVE:
In 2009, the National Children’s Study (NCS) Vanguard Study tested the feasibility of household-based recruitment and participant enrollment using a birth-rate probability sample. In 2010, the NCS Program Office launched 3 additional recruitment approaches. We tested whether provider-based recruitment could improve recruitment outcomes compared with household-based recruitment.

METHODS:
The NCS aimed to recruit 18- to 49-year-old women who were pregnant or at risk for becoming pregnant who lived in designated geographic segments within primary sampling units, generally counties. Using provider-based recruitment, 10 study centers engaged providers to enroll eligible participants at their practice. Recruitment models used different levels of provider engagement (full, intermediate, information-only).

RESULTS:
The percentage of eligible women per county ranged from 1.5% to 57.3%. Across the centers, 3371 potential participants were approached for screening, 3459 (92%) were screened and 1479 were eligible (43%). Of those 1181 (80.0%) gave consent and 1008 (94%) were retained until delivery. Recruited participants were generally representative of the county population.

CONCLUSIONS:
Provider-based recruitment was successful in recruiting NCS participants. Challenges included time-intensity of engaging the clinical practices, differential willingness of providers to participate, and necessary reliance on providers for participant identification. The vast majority of practices cooperated to some degree. Recruitment from obstetric practices is an effective means of obtaining a representative sample.

Published: June 2016

OBJECTIVE:
Few studies have reported the outcome of direct outreach methods for recruitment of research participants in population-based samples. We describe the relationship of outreach strategies that are tailored to specific community factors to recruitment and consent outcomes in 10 National Children’s Study direct outreach study locations (all were single counties).

METHODS:
Each study center collected data from a target population of women who resided in selected county segments that were sampled based on a geographic area probability sampling design. Based on county characteristics of the 10 study locations, each study center used site-specific marketing approaches (direct mail, mass media, provider referrals, social networking) to recruit study participants. Recruitment success was measured by the number of recruited women as well as by a qualitative assessment of the effectiveness of various recruitment methods.

RESULTS:
The number of women who consented varied from 67 to 792. The majority of women were pregnant at the time of consent. Community awareness varied from &lt;1% to 70%. Although no significant associations were found between community characteristics and recruitment success, we found that certain types of outreach strategies enhanced recruitment.

CONCLUSIONS:
In a small sample of 10 US counties, recruitment success was not associated with community characteristics. It was, however, associated with certain types of outreach strategies that may be more effective in close-knit communities.

Published: June 2016

BACKGROUND:As a result of antenatal screening, abortion of fetuses with Down syndrome has become increasingly common. Little is known about the cardiovascular phenotype in infants with Down syndrome born today.METHODS:Population-based cohort study based on national health registers including 2588 infants with Down syndrome, live-born in Sweden from 1992 to 2012. Risk ratios for congenital heart defects were calculated per 3-year period, adjusted for maternal age, parity, BMI, smoking, diabetes and hypertensive disease, and infant gender.RESULTS:Any congenital heart defect was diagnosed in 54% of infants with Down syndrome. Overall, year of birth was not associated with risk of any congenital heart defect. However, the risk of complex congenital heart defects decreased over time. Compared with 1992 to 1994, the risk in 2010 to 2012 was reduced by almost 40% (adjusted risk ratio 0.62, 95% confidence interval 0.48–0.79). In contrast, risks for isolated ventricular septal defect (VSD) or atrial septal defect showed significant increases during latter years. Overall, the 3 most common diagnoses were atrioventricular septal defect, VSD, or atrial septal defect, accounting for 42%, 22%, and 16% of congenital heart defects, respectively. Although atrioventricular septal defect was far more common than VSD in 1992 to 1994, they were equally common in 2010 to 2012.CONCLUSIONS:Complex congenital heart defects have become less common in infants diagnosed with Down syndrome. This phenotypic shift could be a result of selective abortion of fetuses with Down syndrome, or due to general improvements in antenatal diagnostics of complex congenital heart defects.
The Challenge Of Botsourcing
Authors: Vedder Richard , Guynes Carl S. 
Published: June 2016

Botsourcing is the augmentation or replacement of human jobs by robots or other computing systems. This practice is growing in popularity for reasons both economic and technical. Botsourcing will seriously challenge the human workforce, and in some cases humans will find themselves working alongside robots or other “intelligent’ computer systems. In other cases, botsourcing will eliminate jobs and will force impacted humans to retrain. This paper discusses the nature and appeal of botsourcing, as well as the challenge to human employment.
