Psychological Contracts of Multiple Jobholders: A Multilevel Analysis
Authors: Raeder Sabine
Published: May 2018

Organizational research has paid little attention to multiple jobholders. This study investigated the psychological contracts of multiple jobholders in relation to each employment contract and the nonstandard work arrangement of multiple jobholding. The sample consisted of 141 multiple jobholders with two or more jobs and either employed or self-employed status. The results of the multilevel analyses indicated that, with one exception, psychological contract obligations vary more between employment relationships than between individuals. Multiple jobholders’ psychological contracts are only partly related to the terms of their employment contracts and their nonstandard work arrangement. This study connects mainly economic knowledge on multiple jobholders to the organizational variable psychological contracts. Investigating the psychological contracts within and between multiple jobholders helps researchers better understand psychological contracts and how they are related to the job. Typical patterns of multiple jobholders’ employment situation and psychological contracts can thus be identified.

Published: May 2018

Study Design:

Systematic review and meta-analysis.

Objective:

Compare the clinical and radiographic outcomes of anterior cervical discectomy and fusion (ACDF) with a stand-alone interbody cage versus a conventional cage and anterior cervical plate technique.

Methods:

A systematic Medline search was conducted using PubMed, EMBASE, and Cochrane Library Database of Systematic Reviews. Search terms included “anterior cervical discectomy and fusion,” “cage,” and “bone plates,” or variations thereof. Only studies involving a direct comparison of ACDF with a stand-alone cage versus a cage and plate were included. From the selected studies, we extracted data on patient demographics, comorbidities, surgical risk factors, and pre- and postoperative radiographic findings. A meta-analysis was performed on all outcome measures. The quality of each study was assessed using the Downs and Black checklist.

Results:

Nineteen studies met the inclusion and exclusion criteria. Patients who underwent ACDF with a cage-only technique had significantly lower rates of postoperative dysphagia and adjacent segment disease compared with patients who underwent ACDF with a cage-plate technique. However, patients who underwent ACDF with a cage-plate technique had better radiographic outcomes with significantly less subsidence and better restoration of cervical lordosis. There were no other significant differences in outcomes or postoperative complications.

Conclusions:

ACDF with a cage-only technique appears to have better clinical outcomes than the cage-plate technique, despite radiographic findings of increased rates of subsidence and less restoration of cervical lordosis. Future randomized controlled trials with longer term follow-up are needed to confirm the findings of this meta-analysis.

Published: May 2018

Study Design:

Retrospective cohort.

Objectives:

Parkinson’s disease (PD) is a neurodegenerative condition associated with significant morbidity and mortality. PD patients often develop spinal conditions and are known to have high complication rates following surgery. This study evaluated the outcomes of lumbar fusion surgery in patients with PD using a large, public, national database.

Methods:

The Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) was used to identify elective lumbar spinal fusion patients with and without PD for the years 2000 to 2012. PD patients were matched with non-PD controls for comorbidity and age using propensity score matching. Univariable and multivariable logistic regression were used to determine the relationship between PD and surgical outcomes in the matched cohort.

Results:

A total of 231 351 elective lumbar fusion patients were examined, of which 1332 had PD. Before matching, elective lumbar fusion patients with PD were significantly older ( P < .001) and more likely male ( P < .001) compared with non-PD patients. In the matched cohort, PD was associated with increased length of stay (6.91 vs 5.78 days) ( P < .001) and total hospital charges ($129 212.40 vs $110 324.40) ( P < .001). There was no significant difference in overall in-hospital complication rate between PD patients and matched non-PD patients (22.3% vs 21.4%) ( P = .524).

Conclusions:

Analysis demonstrated significant increases in length and cost of hospitalization for elective lumbar spinal fusion in patients with PD. However, inpatient complication rates in PD patients were not significantly increased. As a growing number of PD patients undergo elective spine surgery, further studies are needed to optimize operative planning. Further study is needed to assess the long-term outcomes of lumbar spinal fusion in PD.
Parametric study on the recast layer during EDWC of a Ni-rich NiTi shape memory alloy
Authors: Shandilya Pragya , Bisaria Himanshu , Jain P. K.
Published: May 2018

Shape memory alloys (SMAs) have exceptional properties, namely, shape memory effect, superelasticity and other enriched physical and mechanical properties. The conventional machining of these alloys is associated with several severe difficulties. Electric discharge wire cutting (EDWC), an advanced machining process, is utilized to machine Ni50.89Ti49.11 SMA under this investigation. The aim of this investigation was to reveal the effect of EDWC variable parameters such as pulse on time ( TON), wire feed (WF) rate, spark gap voltage (SV), wire tension (WT) and pulse off time ( TOFF) on recast-layer thickness (RLT) and a foreign element atomic content (FEAC) using the one-factor-at-a-time approach. Scanning electron microscope equipped with energy dispersive X-ray spectroscopy facility was utilized to analyse RLT and FEAC. RLT and FEAC are varied linearly and nonlinearly respectively with TON, TOFF and SV. A thick recast layer with a high percentage of FEAC was formed on the machined surface of Ni50.89Ti49.11 SMA at a higher TON and a lower TOFF and SV. However, RLT and FEAC are slightly varied with WF and WT.
Classification of the minerals of the graftonite group
Authors: Hawthorne Frank C. , Pieczka Adam
Published: May 2018

A classification and nomenclature scheme has been approved by the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification for the minerals of the graftonite group. The crystal structures of these minerals have three distinct sites that are occupied by Fe2+, Mn2+and Ca2+. These sites have coordination numbers [8], [5] and [6], and these differences lead to very strong order of Fe2+, Mn2+and Ca2+over these sites. As a result of this strong order, the following compositions have been identified as distinct species: graftonite: FeFe2(PO4)2; graftonite-(Ca): CaFe2(PO4)2; graftonite-(Mn): MnFe2(PO4)2; beusite: MnMn2(PO4)2; and beusite-(Ca): CaMn2(PO4)2.

Published: May 2018

This study investigated the impact of different dietary ingredients with different protein/lipid sources on the midgut and feaces bacteria communities structure just before feeding and 3h after feeding a single meal on rainbow trout (Oncorhynchus mykiss) individuals. Fish were kept in experimental rearing facilities and fed ad libitum two times daily for five weeks. Fish were fed three different commercial diets containing a higher marine fishmeal/fish oil and a lower marine fishmeal/fish oil content. DNA was extracted from midgut and faeces samples for the analysis of their bacterial 16S rRNA gene diversity by targeting the V3-V4 region with 454 pyrosequencing. A total of 332 unique bacterial operational taxonomic units (OTUs) were revealed in all samples. However, each sample was dominated (>80% relative abundance) by 2–14 OTUs with the single most dominant OTU having >30% dominance, indicating only a few bacteria were fundamental in terms of relative abundance in each treatment. Fifteen OTUs occurred in all samples (core microbiota). The majority of these OTUs belonged to the Proteobacteria, Firmicutes and Tenericutes and were associated with other animal gut environments. The faecal material and the midgut samples had little overlaps in their shared OTUs. A postprandial response in the gut bacterial community structure 3 h after feeding a single meal highlights how dietary stimulation induce structural changes in the microbiota profiles in the established gut bacteria. This study showed that feeding different diets and even single meals lead to perturbations in the established gut bacteria of O. mykiss.
Inhibition of TBC1D5 activates Rab7a and can enhance the function of the retromer cargo-selective complex
Authors: Seaman Matthew N. J. , Mukadam Aamir S. , Breusegem Sophia Y.
Published: May 2018

The retromer complex is a vital component of the endosomal protein sorting machinery necessary for sorting into both the endosome-to-Golgi retrieval pathway and also the endosome-to-cell-surface recycling pathway. Retromer mediates cargo selection through a trimeric complex comprising VPS35, VPS29 and VPS26, which is recruited to endosomes by binding to Rab7a and Snx3. Retromer function is linked to two distinct neurodegenerative diseases, Parkinson's disease and Alzheimer's disease and modulating retromer function has been proposed as an avenue to explore for a putative therapy in these conditions. We hypothesised that activating Rab7a to promote the recruitment of retromer to endosomes could positively modulate its activity. Here, we show that inhibition of the GTPase activating protein TBC1D5 can enhance Rab7a activation and lead to a gain of function for retromer.
Towards precision medicine: The application of omics technologies in asthma management
Authors: Scelfo Chiara , Galeone Carla , Bertolini Francesca , Caminati Marco , Ruggiero Patrizia , Facciolongo Nicola , Menzella Francesco
Published: May 2018

Asthma is a chronic obstructive respiratory disease characterised by bronchial inflammation. Its biological and clinical features have been widely explored and a number of pharmacological treatments are currently available. Currently several aspects of asthma pathophysiological background remain unclear, and this is represent a limitation for the traditional asthma phenotype approach. In this scenario, the identification of new molecular and clinical biomarkers may be helpful in order to better understand the disease, define specific diagnostic tools and highlight relevant novel targets for pharmacological treatments. Omics technologies offer innovative research tools for addressing the above mentioned goals. However, there is still a lot to do both in the fields of basic research and in the clinical application. Recently, genome-wide association studies, microRNAs and proteomics are contributing to enrich the available data for the identification of new asthma biomarkers. A precise approach to the patient with asthma, particularly with severe uncontrolled asthma, requires new and specific therapeutic targets, but also proper tools able to drive the clinician in tailoring the treatment. On the other hand, there is a need of predictors to treatment’s response, particularly in the field of biological drugs, whose sustainability implies a correct and precise selection of the patients. Translating acquired omics knowledge in clinical practice may address the unmet needs described above, but large-scale studies are required in order to confirm their relevance and effectiveness in daily practice. Thus in our opinion the application of omics is still lagging in the real-life setting.

Authors: Банникова Л. , Bannikova L. , Нидергаус Е. , Nidergaus E.
Published: May 2018

The article is devoted to the analysis of the academic professionals’ occupational health, which largely determines the qualifi ed high school workers’ innovative potential. The academic environment’s transformation, the conversion of teachers into ordinary employees changes their purpose and motivation for their professional activity. At the same time the choice of the academic professional’s behavior strategy depends on the reserves of human and social capital and on the resource possibilities of age cohorts. The conclusions are based on empirical research in the case-study style, occuring on the regional academic labor market, on the analysis of resources and young teachers and “age” professors’ professional perspectives. Analysis of the material of the local sociological study of the Ural Federal University teachers’ professional health led to the conclusion that the professional identity of young teachers can’t be formed completely under the infl uence of changes in the academic environment due to the lack of oneness in the understanding the teaching profession’s purposes and the weakness of the valueregulatory features of life and science activity’s professional continuity.

Published: May 2018

El presente artículo de reflexión, muestra los resultados del análisis de algunos planteamientos del filósofo alemán Friedrich Wilhelm Nietzsche y, lo que ellos implican para las organizaciones y su administración. Se destaca la posibilidad de justificar que, desde el filósofo alemán, se pueda proponer una visión de corte humanista para la gestión del talento humano en las organizaciones; se plantea que, concebir las organizaciones como un medio para favorecer el avance de sus integrantes hacia el superhombre es una concepción valiosa; y que ellas, son espacios propicios para que los seres humanos a partir del trabajo generen condiciones desde lo individual para la realización de sus potencialidades. Se abordan los temas sobre ‘las transformaciones del espíritu’, la ‘voluntad de poder’ y el ‘eterno retorno’. Se busca acercar la filosofía al campo de la administración, para enriquecer la discusión sobre sus problemas fundamentales, que superan el nivel meramente técnico predominante en la comunidad de interesados en la relación filosofía-administración.

Sustaining change towards racial equity through cycles of inquiry
Authors: Dowd Alicia C. , Liera Román
Published: May 2018

Many national, state, and institutional policies and initiatives advocate for change in higher education through structured forms of data use. The case study of “Old Main University” presented in this article shows how local reformers (n=9) drew on data and data use tools provided by a long-term action research project implemented at the university to advance racial equity goals at their university. The case narrative utilizes practice theory, cultural historical activity theory (CHAT), and narrative inquiry to illustrate how administrative leaders and faculty at Old Main University coordinated their efforts in a sustained manner through two cycles of practitioner inquiry that was responsive to policy goals. The findings show that data use is productive to promote racial equity when data and data use protocols are used iteratively and in interaction among practitioners who use them to identify inequities rooted in their own practices. The findings support the conclusion that, to sustain change efforts as long-term (mesogenetic) projects, policy makers and local reformers should plan to iteratively redesign data tools, practices, and policies to institute changes in everyday (microgenetic) work practices. Such purposeful redesign holds potential to re-structure professional interactions, sustain motivation and organizational learning, and acculturate practitioners to equity as a standard of practice.

Modelling the degree of porosity of the ceramic surface intended for implants
Authors: Stach Sebastian , Kędzia Olga , Garczyk Żaneta , Wróbel Zygmunt
Published: May 2018

The main goal of the study was to develop a model of the degree of surface porosity of a biomaterial intended for implants. The model was implemented using MATLAB. A computer simulation was carried out based on the developed model, which resulted in a two-dimensional image of the modelled surface. Then, an algorithm for computerised image analysis of the surface of the actual oxide bioceramic layer was developed, which enabled determining its degree of porosity. In order to obtain the confocal micrographs of a few areas of the biomaterial, measurements were performed using the LEXT OLS4000 confocal laser microscope. The image analysis was carried out using MountainsMap Premium and SPIP. The obtained results allowed determining the input parameters of the program, on the basis of which porous biomaterial surface images were generated. The last part of the study involved verification of the developed model. The modelling method was tested by comparing the obtained results with the experimental data obtained from the analysis of surface images of the test material.
Benenti Tensors: A useful tool in Projective Differential Geometry
Authors: Manno Gianni , Vollmer Andreas
Published: May 2018

Two metrics are said to be projectively equivalent if they share the same geodesics (viewed as unparametrized curves). The degree of mobility of a metric g is the dimension of the space of the metrics projectively equivalent to g. For any pair of metrics (g, ḡ) on the same manifold one can construct a (1, 1)- tensor L(g, ḡ) called the Benenti tensor. In this paper we discuss some geometrical properties of Benenti tensors when (g, ḡ) are projectively equivalent, particularly in the case of degree of mobility equal to 2.
The Strategies of Ultranationalist Discourse: This Is England and Brexit
Authors: Valdés-Miyares J. Rubén
Published: May 2018

A speech given by the skinhead Combo in the film This is England (2006) provides the ground for an analysis of far-right nationalism. This article uses Critical Discourse Analysis and the idea of the nation as a discursive construct to explain Combo’s strategies to gain dominance over his gang by means of rhetoric, body language, building up an ethos based on Christian and epic mythologies with ethnic connotations, drawing boundaries, and discrediting and excluding his opponents. These strategies are then compared to those of the UKIP leader Nigel Farage in his “Brexit victory” speech delivered in June 2016, which was based on a mystification of territorial boundaries, symbolic allusions to a defensive war, and a verbal construction of an ideally independent nation and a promising future. Thus, the article argues that analysis of a scene from the film set in the Thatcherite Britain of 1983 can still illuminate the articulation of later nationalist discourses.
Deindustrialization and Unsustainable Debt in Middle-Income Countries: The Case of Puerto Rico
Authors: Caraballo-Cueto Jose , Lara Juan
Published: May 2018

Puerto Rico recently became the largest bankruptcy case in the history of the U.S. municipal bond market. This debt crisis has not been the subject of significant scrutiny in the economic literature, though many researchers focus on case studies, such as Greece and Argentina, to analyze a country’s indebtedness. The underlying economic factors that influence unsustainable debt in upper middle-income countries are generally understudied. We attempted to contribute to filling these gaps in the related literature. Using econometric analysis, we found that Puerto Rico’s government indebtedness is, to a large extent, connected to a sharp decrease in manufacturing employment (i.e. deindustrialization) suffered by this economy, and weak evidence that it was caused by an excessive government payroll or overgenerous federal programs. In light of our empirical results, we discussed how the consequences of deindustrialization ultimately led to increase government borrowing.

Authors: Selvarani K. , Mahalakshmi R. , Thanuja B.
Published: May 2018

Co-crystals of L-phenylalanine hydrochloride (LPAHCl) were grown by slow evaporation technique in the presence of manganese sulphate and cadmium chloride. Crystallinity of the grown crystals was confirmed by single crystal X-ray diffraction. Optical transmission spectra showed very high transmittance in the entire visible region. The cut-off wavelength was observed at 250 nm for both the crystals. The optical band gap energy was found to be 4.37 eV and 4.31 eV for the grown co-crystals of LPAHCl with MnSO4 and CdCl2, respectively. The second harmonic generation of the grown crystals was confirmed by Kurtz and Perry powder SHG method and compared with KDP. The frequency dependent dielectric properties of the co-crystals were studied at different temperatures.

Background and aims

Research investigating differences in pain location and distribution across conditions is lacking. Mapping a patient’s pain may be a useful way of understanding differences in presentations, however the use of pain mapping during a pain provocation task has not been investigated. The aim of this study was to assess the reliability of patient and clinician rated pain maps during a pain provocation task for the anterior knee.

Methods

Participants were recruited from a larger study of professional Australian rules football players (n=17). Players were invited to participate if they reported a current or past history of patellar tendon pain. No clinical diagnosis was performed for this reliability study. Participants were asked to point on their own knee where they usually experienced pain, which was recorded by a clinician on a piloted photograph of the knee using an iPad. Participants then completed a single leg decline squat (SLDS), after which participants indicated where they experienced pain during the task with their finger, which was recorded by a clinician. Participants then recorded their own self-rated pain map. This process was repeated 10 min later. Pain maps were subjectively classified into categories of pain location and spread by two raters. Pain area was quantified by the number of pixels shaded. Intra- and inter-rater reliability (between participants and clinicians) were analysed for pain area, similarity of location as well as subjective classification.

Results

Test-retest reliability was good for participants (intraclass correlation coefficients [ICC]=0.81) but only fair for clinicians (ICC=0.47) for pain area. There was poor agreement between participants and clinicians for pain area (ICC=0.16) and similarity of location (Jaccard index=0.19). Clinicians had good inter- and intra-rater reliability of classification of pain spread (k=0.75 and 0.67).

Conclusions

Participant completed pain maps were more reliable than clinician pain maps. Clinicians were reliable at classifying pain based on location and type of spread.

Implications

Clinicians should ask patients to complete their own pain maps following a pain provocation test, to elicit the most reliable and consistent understanding of their pain perception.

The degradation behaviors and mechanisms of nitrile butadiene rubber O-rings aged in air are investigated by accelerated aging tests at different temperatures. The compressive stress changes of nitrile butadiene rubber O-rings are monitored by using a self-designed test device during the degradation process. The aging samples under different conditions are evaluated by measuring attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy, crosslinking density, compressive stress relaxation, weight loss, mechanical properties, and fracture morphology. The results demonstrate that the compressive stress declines with aging time, and the higher the temperature is, the faster the stress decreases. The ATR-FTIR results indicate that amide groups and hydroxyl groups are formed during the degradation process. The elevated temperature plays a significant role in the surface chemical changes. The changes in the crosslinking density of the samples could be attributed to the competition between crosslinking and chain scission, and the crosslinking mainly predominates in the aging process. The results of mechanical properties show that the tensile strength, elongation at break, and hardness of samples changes significantly with aging time and temperature. In addition, the fracture morphology observation reveals that the formation of a hardened brittle outer layer, voids, and agglomerates lead to a further decrease in mechanical properties. These results are very important for evaluating the lifetime of rubber O-rings and can be utilized to improve the stability and durability of sealing systems.

The present experimental investigation includes finding the variation of drag coefficient, wall static pressures, and aerodynamic drag over a vehicle for twenty-six different orientations of vehicle. The flow was controlled using the submerged type vortex generator (VG) in combination with the rear spoiler during the investigation. The model of a vehicle was fabricated on the reducing scale (15:1) using the Plaster of Paris (PoP). Primarily, the vehicle was tested at the different incidence yaw angles to obtain the totaldrag over the model. Further, twenty-six different combinations obtained by changing the flow angles (β = 0 and ±30°), spoiler angles (α =0 and ±45°) and orientations of VGs were tested. A variation of static pressures and drag coefficients for all combinations was analyzed. Further, the development of secondary-flow was also traced. Secondary flow becomes important as it causes a sheared flow produced near the body and wall of a sadden vehicle which further deflects the air pressure on the roof of the vehicle body. The variation of the secondary flow was obtained with the wall static pressure, surface static pressure and boundary layer by changing the flow angles ( β = 0 and ±30°), and spoiler angles (α =0 and ±45°) and orientations of VGs. The best combination in terms of surface static pressure coefficient (Cwp) rise (from –0.041 to +2.622) is found at β = 0°, α = 0° and the VG attached to the upstream of the spoiler. CFD analysis is conducted using ANSYS FLUENT® and Solid Works was used for building the geometries of the car andspoiler. A formulated computational fluid dynamics model is in good match with the experimental results.
Surrealism in Budi Darma’s Laki – Laki Pemanggul Goni (The Man Carrying the Sack): A Comparative Study
Authors: Harendika Melania Shinta
Published: May 2018

Laki – laki Pemanggul Goni is one of Budi Darma‘s short stories. It was firstly published in Kompas, 26 February 2012, and was then translated by Andy Fuller in 2015. Lontar Foundation published the translated version along with the other translated Budi Darma‘s short stories in a book entitled Conversations. Budi Darma is famous of his surrealist work. It is reflected also in Laki – laki Pemanggul Goni. Therefore, this study was intended to find whether its‘ English version conveyed exactly the same characteristics of surrealism as it was in the original version. Bassnett‘s translation as comparative studies, Popovics‘ types of translation equivalence, and Breton‘s surrealism in literature were implemented as the theoretical framework. This study found that both versions did not convey precisely the identical characteristics of surrealism. The Indonesian version‘s surrealism is stronger than it is in the English version. It might occur because of the cultural gap between the author‘s and the translator‘s.

Williams Syndrome (WS) is a rare
congenital and progressive multisystem disorder which is described with
specific systemic disorders, skeletal and dental abnormalities and tongue
thrusting. A 13-year-old patient applied to our clinic with complaining dental
caries, malocclusion and tongue thrusting. The patient was treated with a full fixed standard
edgewise appliance named as Mini Master Series from American Orthodontics
(Central Islip, N.Y., USA), 0.018
inch bracket slots) for
2 years and 8 months.

Despite poor oral hygiene, frequent
appointments helped to complete the orthodontic treatment of the patient
without caries formation. Also extraction of first molars with uncertain
prognosis provided social benefits when it was compared to healthy premolar
extractions. This case report presents the successful results of the
orthodontic therapy and difficulties of an orthodontic treatment of a patient
who was diagnosed with WS.
Szinuszhullámú és amplitúdómodulált beszéd észlelésének vizsgálata Magyar mondatok segítségével

Háttér és célok: Kutatásunkban elszegényített beszédingerek két típusát használtuk gyerekek és felnőttek beszédészlelési képességének vizsgálatára.

Módszer: Vizsgálatunkat 5-6 éves gyermek és felnőtt mintán végeztük, szinuszhullámú és amplitúdómodulált beszédingerek – magyar nyelvű mondatok – segítségével. Beszédingereinket természetes kiejtésű változatokból szintetizáltuk.

Eredmények: Korábbi angol nyelvű vizsgálatok eredményeihez hasonlóan azt tapasztaltuk, hogy mindkét korcsoport igen jól érti ezeket a szintetizált beszédfajtákat, bár a felnőttek jobban teljesítenek a gyerekeknél. Ugyanakkor adataink eltérő képet mutatnak a kétféle szintézistípus viszonyáról az angol nyelvű vizsgálatokhoz képest. Míg angol anyanyelvű mintáknál a gyerekek a szinuszhullámú beszédet relatíve jobban értették, mint az amplitúdómoduláltat, felnőtteknél pedig ez a viszony megfordult, a magyar nyelvű vizsgálatok esetén gyerekeknél egyforma teljesítményt találtunk a kétféle ingertípusra, míg felnőtteknél az amplitúdómodulált ingerek előnyét találtuk (lehetséges ugyanakkor, hogy ez csak az ingernehézségi paraméterek eltérő beállításának következménye). A lexikai restaurációs hatásokat jelezte, hogy a mondatok első főnévi csoportjának felismerése igen erősen korrelált a mondatok további részének felismerésével.

Konklúzió: Adataink részben reprodukálják az angol nyelven végzett vizsgálatok eredményeit. Új eredményként kétféle perceptuális tanulási hatást sikerült elkülönítenünk: az azonnali perceptuális tanulás gyerekeknél és felnőtteknél is megfigyelhető, míg a próbák során jelentkező gyakorlási, tehát az egyes mondatok közötti transzferhatás csak felnőtteknél.
