Committed to change? Human resource management practices and attitudes towards organizational change
Authors: Raeder Sabine , Bokova Mariya V.
Published: November 2019

Organizations rely on human resource management (HRM) practices to steer organizational change, but little is known about the effects of HRM practices on employees’ attitudes towards change. This study aims to investigate the relationship between employees’ perception of HRM practices and their commitment to change. The sample comprised 221 employees of a public organization after it underwent an organizational change. Data were analyzed through structural equation modeling, considering HRM practices as individual predictors or as a second-order factor of aligned HRM practices. The results indicate that the model with individual HRM practices achieved a superior fit, but only two practices – communication and autonomy – were related to affective commitment to change. The model with a second-order factor of aligned HRM practices showed a clear positive relationship with affective and normative commitment to change, and a clear negative relationship with continuance commitment to change. Investing in HRM practices to support an ongoing change helps organizations to convince employees of the necessity and value of the change. This study provides empirical evidence that HRM practices are important for supporting employees’ commitment to change and encouraging their positive behavior towards change.

Authors: Ekici Günay Nahide , Günay Nurullah
Published: November 2019

Background

The erythrocytes distribution indices are reported from same histogram but they have different reference intervals and calculated by distinct measurements.

Objectives

To explore whether the RDW-CV and RDW-SD values may predictive and prognostic significance in ischemic stroke patients and to clarify the relation each of these indices with stroke severity and 3-months survival.

Materials and methods

Cumulative survival rates were calculated with the Kaplan-Meier method, and life curves were compared to RDW-CV, RDW-SD quartiles. The risk factors were described with a multivariable cox proportional hazard model.

Results

In acute ischemic stroke, RDW-CV was more specific and RDW-SD was more sensitive (92% vs. 80%) (52% vs. 48%). RDW-CV values higher than 14.7% are associated with 11-fold increase in the risk of stroke; and the level of RDW-CV does show a linear relationship with the severity of stroke. However, when we evaluated RDW-SD, higher 43.55 fL RDW-SD values was have 16-fold increase in severity of stroke and have a relatively high linear relationship with stroke severity scores to RDW-CV.

Conclusions

RDW-CV and RDW-SD levels have different prognostic poor outcomes for interpreting in ischemic stroke events approach and these should be used alone and comparatively with the AIS predictive and prognostic approach.

Bigg, JL, Gamble, ASD, Vermeulen, TF, Bigg, LM, and Spriet, LL. Sweat loss and fluid intake of female varsity ice hockey players during on-ice practices and games. J Strength Cond Res 34(2): 389–395, 2020—Sweat losses of ∼1.5–2% body mass (BM) during exercise impairs athletic performance in stop and go sports such as ice hockey. The study examined the pre-exercise hydration status, sweat loss, fluid and carbohydrate (CHO) intake, and sodium balance of female hockey players. Twenty-four female varsity hockey players were tested during 2 practices and 4 games. Data analyses were performed using a level of significance of p ≤ 0.05. Over 70% of players arrived at the practices and ∼50% of players arrived at the game mildly dehydrated. Before the high- (P1) and low-intensity (P2) practices, players consumed an average of 0.19 ± 0.14 and 0.15 ± 0.13 L. Before the games, mean fluid intake was 0.39 ± 0.19 L. The sweat rate during P1 was significantly greater than P2 (p = 0.006), but there was no significant difference in total fluid intake between practices (p = 0.279). Consequently, the average BM loss for P1 was significantly greater than that for P2 (p = 0.016). Sweat loss during games was 1.01 ± 0.29 L and fluid intake was 0.70 ± 0.43 L, resulting in minimal BM losses (<1% BM for all players). CHO intake during games was 39.2 ± 22.8 g, with 19/20 players consuming CHO before or during the intermissions of the game. Sweat sodium losses were 0.64 ± 0.34 and 0.32 ± 0.18 g·h−1 for P1 and P2, and 0.83 ± 0.38 g during the game. In conclusion, female ice hockey players replaced the fluid they lost through sweat during practices and games and maintained adequate hydration. Players also consumed adequate CHO during games from the CHO containing food and drinks provided.

Brisola, GMP, Claus, GM, Dutra, YM, Malta, ES, de Poli, RAB, Esco, MR, and Zagatto, AM. Effects of seasonal training load on performance and illness symptoms in water polo. J Strength Cond Res 34(2): 406–413, 2020—The purpose of the study was to describe the training load distribution of a young female water polo team in different cycles of the season and verify its subsequent effects on specific fitness measured by the repeated sprints ability (RSA) test, aerobic endurance measured by the lactate minimum test, incidence and severity of upper respiratory tract infection (URTI) symptoms, and muscle damage markers. The training load (i.e., rating of perceived exertion × session duration) of 20 young female water polo players (mean ± SD: age = 15.65 ± 1.3 years; body mass = 60.93 ± 11.0 kg; height = 1.62 ± 0.1 m) was monitored, and the incidence and severity of URTI was assessed during part of the season. In addition, we assessed the lactate minimum speed (LMS), RSA, creatine kinase (CK), and lactate dehydrogenase (LDH) blood concentration during the season. The level of significance set was p < 0.05. The training loads were higher in the specific period (p < 0.01), whereas a high incidence of URTI was observed in the general cycle. The LMS was greater in the general cycle (p < 0.05), whereas total time and best time in the RSA test were greater in the competitive cycle (p < 0.05). The CK and LDH concentrations were significantly lower during the competitive cycle (p < 0.01). The general cycle of a female water polo team is critical regarding URTI and muscle damage, even with smaller training loads than the specific period.
Examination of Significant Binder Aging Due to the Use of Different Anti-Stripping Additives in Polymer and CRM Asphalt Mixtures Using GPC

Published: November 2019

As an anti-stripping agent (ASA), hydrated lime (HL) has been widely used for many years in the world. Many brands of liquid-type ASA (LA), which properly provided the anti-stripping function, have been also developed and marketed. Because HL was found to provide anti-aging function of the binder in the mix, in addition to anti-stripping function, its use was known to have many advantages of other beneficial functions to the asphalt pavement. However, because the anti-aging function of LA is in question, it will be important to recognize if the anti-aging function is presented by the LAs too. Therefore, this study investigated the anti-aging effect of HL and three LAs in normal, crumb rubber–modified and polymer-modified asphalt mixes, in terms of absolute viscosity (AV) estimated from the large molecular size (LMS) measured by gel permeation chromatography (GPC), a scientific equipment. It was found that HL provided a significant retardation of age hardening, compared with the binder of the mix without any ASA. However, unlikely the anti-stripping function, most of the LAs did not show age retardation effect. The anti-aging function of liquid additives was not proved in this study, and therefore, the significant difference in binder aging was present due to the use of different ASA.

To enable Industry 4.0 successfully, there is a need to build a resilient automation system that can quickly recover after having been attacked or robustly sustain continued operations while being threatened, enable an automated monitoring evolution via various sensor channels in real time, and use advanced machine learning and data analytics to formulate strategies to mitigate and eliminate faults, threats, and malicious attacks. It is envisioned that if we can develop an intelligent model that (a) represents a meaningful, realistic environment and complex entity containing manufacturing Internet of Things interdependent and independent properties that are stepping-stones of the cyber kill chain or precursors of the onset of cyberattacks; (b) can learn and predict potential errors and formulate offense/defense strategies and healing solutions; (c) can enable cognitive ability and human-in-the-loop analytics in real time; and (d) can facilitate system behavior changes to disrupt the attack cascade, then the hosting system can learn how to neutralize threats and attacks and self-repair infected or damaged links autonomously. In this article, our preliminary work presents a visual analytics framework and technique for situational awareness, including autonomously monitoring, diagnosing, and prognosticating the state of cyber-physical systems. Our approach, presented in this article, relies on visual characterizations of multivariate time series and real-time predictive analytics to highlight potential faults, threats, and malicious attacks. To validate the usefulness of our approach, we demonstrate the developed technique using various aviation datasets obtained from the Prognostics Center of Excellence at the National Aeronautics and Space Administration Ames.

Published: November 2019

O impacto das mudanças climáticas sobre a precipitação e a temperatura média pode alterar consideravelmente a disponibilidade de recursos ambientais, principalmente para países em desenvolvimento. A região da Bacia do Rio Taquari-Antas é economicamente importante para o Estado. Por isso, o objetivo deste trabalho foi detectar alterações nos padrões de precipitação e temperatura na bacia desses rios, comparando dados atuais com os futuros. Foram utilizados os dados das projeções de precipitação e temperatura para 3 pontos na bacia, referentes aos períodos de 1961-1990 e 2011-2100 gerados por modelos de circulação global e modelos de circulação regional, para o cenário climático A1B. As projeções indicaram um aumento de temperatura média anual de quase 3°C até o final do século, bem como um aumento expressivo na precipitação anual acumulada. Os ciclos mensais de precipitação e temperatura demonstram que os meses das culturas de verão serão menos afetados pelo aumento destas variáveis, porém os possíveis extremos aparecerão no início dos cultivos devido ao aumento de precipitação nos meses de outubro e novembro.

Rationality is Gendered
Authors: Pavco-Giaccia Olivia , Little Martha Fitch , Stanley Jason , Dunham Yarrow
Published: November 2019

Shared rationality is the common ground of scientific progress. However, some theorists have argued that this common ground may not be level, in that subtle assumptions embedded within lay views of rationality marginalize some would-be participants. Specifically, feminist philosophers have argued that rationality is associated with male rather than female discourse. This claim has frequently been dismissed as incoherent, but a straightforward interpretation is readily available: The concept reason is semantically associated with the concept male. We support this hypothesis in four studies (total N > 900), finding that at both the explicit and implicit level, reason is preferentially associated withmale, feeling is preferentially associated withfemale, male faces prime unrelated judgments of reason/rationality, and gendered associations are related to interest in academic disciplines as well as estimates of the (mis)representation of women within those disciplines. Implications for gender stereotyping and the representation of women in different fields are discussed.

Published: November 2019

Shiraia bambusicola is a rare medicinal fungus found in China that causes bamboo plants to decay and die with severe infection. Hypocrellin, its main active ingredient, is widely used in several fields, such as medicine, agriculture, and food industry. In this study, to clarify the genomic components, taxonomic status, pathogenic genes, secondary metabolite synthesis pathways, and regulatory mechanisms of S. bambusicola, whole-genome sequencing, assembly, and functional annotation were performed using high-throughput sequencing and bioinformatics approaches. It was observed that S. bambusicola has 33 Mb genome size, 48.89% GC content, 333 scaffolds, 2590 contigs, 10,703 genes, 82 tRNAs, and 21 rRNAs. The total length of the repeat sequence is 2,151,640 bp. The annotation of 5945 proteins was obtained from InterProScan hits based on the Gene Ontology database. Phylogenetic analysis showed that S. bambusicola belongs to Shiraiaceae, a new family of Pleosporales. It was speculated that there are more than two species or genus in Shiraiaceae. According to the annotation, 777 secreted proteins were associated with virulence or detoxification, including 777 predicted by the PHI database, 776 by the CAZY and Fungal CytochromeP450 database, and 441 by the Proteases database. The 252 genes associated with the secondary metabolism of S. bambusicola were screened and enriched into 28 pathways, among which the terpenoids, staurosporine, aflatoxin, and folate synthesis pathways have not been reported in S. bambusicola. The T1PKS was the main gene cluster among the 28 secondary metabolite synthesis gene clusters in S. bambusicola. The analysis of the T3PKS gene cluster related to the synthesis of hypocrellin showed that there was some similarity between S. bambusicola and 10 other species of fungi; however, the similarity was very low wherein the highest similarity was 17%. The genomic information of S. bambusicola obtained in this study was valuable to understand its genetic function and pathogenicity. The genomic information revealed that several enzyme genes and secreted proteins might be related to their host interactions and pathogenicity. The annotation and analysis of its secondary metabolite synthesis genes and gene clusters will be an important reference for future studies on the biosynthesis and regulation mechanism of the secondary metabolites, contributing to the discovery of new metabolites and accelerating drug development and application.

Introducción: El uso de los sistemas placa/tornillo deslizante para fracturas intertrocantéricas ha demostrado ser un método de fijación eficaz, pero no está exento de fallas. El propósito de este estudio fue evaluar las causas de falla en los pacientes con fracturas laterales de cadera, tratados con placa/tornillo deslizante, puntualizando los defectos técnicos en la colocación.Materiales y Métodos: En nuestro centro, se trató a 177 pacientes por fractura lateral de cadera, a 151 de ellos se les practicó osteosíntesis con placa/tornillo deslizante. Se analizaron la adecuada reducción posoperatoria, la medición de la distancia punta a vértice, la posición del tornillo cefálico en la cabeza femoral y las posibles complicaciones.Resultados: La serie quedó conformada por 143 pacientes. El seguimiento promedio fue de 18 meses (rango 12-48). La tasa de fallas fue del 8,4% (n = 12): 7 (4,8%) por migración cefálica (cut-out) del tornillo proximal, 2 (1,4%) por migración medial (cut-through), 2 (1,4%) presentaron seudoartrosis y un caso (0,70%) de reducción inadecuada en varo. El porcentaje de una segunda operación fue del 7,7% (n = 11). La peor posición fue la superior/posterior con un 100% de migración (n = 4) (p <0,001, diferencia estadísticamente significativa).Conclusión: El posicionamiento superior/posterior del tornillo cefálico podría incrementar la posibilidad de migración y, en consecuencia, la tasa de falla del sistema. AbstractIntroduction: The use of Dynamic Hip/Sliding Screw (DHS) for intertrochanteric fractures has proven to be an effective fixation method, but it also has its failures.The purpose of this study was to evaluate the reason of failures in patients with lateral hip fractures that were treated with a DHS.Method:177 patients were treated in our center for lateral hip fracture. In 151 of them we used a DHS. The adequate postoperative reduction, the measurement of the tip-to-apex distance, the position of the cephalic screw in the femoral head and the possible complications were analyzed.Results: The series was made up of 143 patients. The average follow-up was 18 months (range 12-48). The failure rate was 8.4% (n = 12): 7 (4.8%) due to cephalic migration (cut-out) of the proximal screw, 2 (1.4%) due to medial migration (cut-through) , 2 (1.4%) presented pseudoarthrosis and one case (0.70%) of inadequate reduction in varus. The percentage of a second operation was 7.7% (n = 11). The worst position was the superior / posterior with 100% migration (n = 4) (p <0.001, statistically significant difference).Conclusion: The superior / posterior positioning of the head screw could increase the possibility of migration and, consequently, the failure rate of the system.
Institutional dilemmas and challenges in the territorial construction of peace
Authors: Restrepo Botero Dario I. , Peña Galeano Camilo A.
Published: November 2019

Implementation of the peace accords signed by the Colombian government and the leadership of FARC-EP will have strong institutional constraints. The central dilemma of the integration of post-conflict territories to the nation is the following: Will the State be taken to the provinces, or will the State be built from below, through strong social participation and a lasting local institutional creation? Although the agreements signed are part of the centralist tradition of building the national State from the top, they also provide space for significant reforms that would deepen the decentralisation process. To contribute to the public debate on the "territorial and differentiated construction" of peace, this essay reflects on how to operate in the 170 municipalities prioritised for intervention and proposes a series of institutional reforms not foreseen in the agreements, which would facilitate territorial State-building.

ABSTRACT-QMFS2019Poultry production provides source of protein and contributes an important income for Vietnamese farmers. Among the poultry in Vietnam, ducks account for 27.3% of head of poultry and even 55.7% in Mekong Delta region. Along with the development of rearing ducks, bacterial, viral and fungal diseases occurring in the two last decades induced bad effect for poultry producer. Escherichia coli, Salmonella enterica, Streptococcal or Pasteurella act as major pathogenic bacteria in duck. The aims of this study were to investigate the antibacterial activity of garlic Allium sativum against E. coli, Staphylococcus aureus, Salmonella Typhimurium and to evaluate the effect of garlic on growth performance of duck from 1-28 old-days. The results indicated that fresh garlic and dried garlic powder showed inhibitory effect against pathogenic tested strains from 2% and 4% w/v, respectively. The inhibition zones and the minimal inhibitory concentration (MIC) values of garlic extract ranged from 11.3-28.3 mm and 0.02-0.2 g/ml, respectively. After 28 days of diet with garlic supplemented, D3 (2% of fresh garlic in water) showed significantly different in weight gain (WG), feed conversion ratio (FCR), protein efficiency ratio (PER), average daily weight (ADW); whereas, D2 (2% of garlic powder in basal diet) only possessed a difference significant in feed consumption (FC) compared to the D1 (control without garlic supplementation). The obtained results demonstrated the potential of garlic application in poultry production.

This research focused on technical assessment of GABA production from rice bran through fermentation by Lactobacillus brevis. Influence of operating pressure on separation of GABA by nanofiltration membrane was investigated and 4 bar was suitable for the nanofiltration process. The purification of GABA by nanofiltration with constant feed volume was carried out and purity of GABA reached 4.8 folds, compared to feed, at 5 volumes of added water. At 40 of concentration factor in concentration of GABA solution by nanofiltration with full recycle of retentate, content of GABA reached 49.8 g/L. The production of GABA from defatted rice bran at pilot scale was carried out at 1,000 L/batch (equal to 200 kg of rice bran) of fermentation. Estimation of mass balance showed that, with 200 kg of defatted rice bran, 7.0 kg of GABA powder was obtained. Results indicated that, it is potential to produce GABA from rice bran through the fermentation by Lactobacillus brevis.

Published: November 2019

This article was migrated. The article was marked as recommended. Introduction: The initial history and examination is a fundamental aspect of clinical practice. Most medical students cultivate this skill through regular undertaking of 'clerkings' during their clinical placements. We designed a written, structured, proforma-based approach to delivery of feedback on student clerkings which also promoted the undertaking of a 'complete clerking' encouraging students to maintain a whole-system holistic approach. Within this paper, we present our findings following its introduction at a London teaching hospital. Methods: Sixty-one medical students on their first clinical attachment within acute medicine were asked to submit at least one full medical clerking for objective appraisal using the structured clerking feedback proforma by a clinical teaching fellow. Students completed a 'pre' and 'post' assessment using Likert Scales at the time of receiving their clerking feedback. Structured interviews of randomly selected students and senior medical educators were also undertaken. Results: Following introduction of the structured feedback proforma, there was a significant increase across all indices of student-perceived utility and satisfaction compared to previously received feedback (which was mostly ad-hoc verbal). Using Likert Scales (1 to 10: 1 representing least effect and 10 representing greatest effect) student assessment of usefulness was 9.0 (versus 6.34 for previous feedback); likelihood of influencing future practice was 8.8 (versus 6.47); extent to which it reinforced the message of a complete clerking was 9.5 (versus 6.13) and extent to which the feedback would encourage them to undertake complete clerkings was 9.0. Free text comments and subsequent interviews of randomly selected students and senior medical educators reinforced the positive perception of this approach. Conclusions: The introduction of a structured clerking feedback proforma can improve the quality and utility of the feedback delivered to medical students on their acute medical clerkings and can promote and reinforce the value of maintaining a whole-system holistic approach.

ÖZET

İnvajinasyon
proksimal bir bağırsak segmentinin distal bağırsak segmenti içine girmesidir.
Genellikle çocuklarda karşımıza çıkan bir patoloji olmasına karşın erişkinde de
nadir de olsa karşılaşılmaktadır. Atipik klinik seyrinden dolayı bazı
hastalarda preop tanısı konulamayabilir. Başvuru anındaki en sık semptom karın
ağrısıdır. Tanısı preop olarak USG, BT ile konulabilir. Bunların içinde tanı
koyma oranı en yüksek olan radyolojik yöntem BT’dir. Tedavisi cerrahidir. İnce
bağırsak kaynaklı olanlarda malignite nadirdir. Ancak kolon kaynaklı
invajinasyonlarda  malignite olasılığı
yüksek olduğu için rezeksiyon yapılırken dikkatli olunmalıdır. Bu yazıda
bahsedilen hasta acile ileus bulgularıyla başvurdu  ve invajinasyon tanısı konuldu. Çekilen
abdomen tomografide  ince bağırsak
kaynaklı olduğu saptandı ve hasta opere edildi. 
Operasyonda jejenum duvarına fiske tümör tespit edildi ve redüksiyon
sonrasında rezeksiyon işlemi uygulandı. Postop takiplerinde komplikasyon olmadı
ve hasta taburcu edildi. Patoloji sonucunda malignite saptanmadı. 

 

 

ABSTRACT

İntussusception
is the condition whereby proximal intestinal segment drawn into the distal
bowel segment. When this disease seen usually a in children, it is rarely seen
in adults. Some patients may not have preop diagnosis due to atypical clinical
picture. The most common symptom is abdominal pain. Diagnosis can be made by
USG, CT as preop. Among them, CT is the radiological method with the highest
diagnostic rate. The main treatment of invagination is surgery. İn the patients
with intussusception of the small intestine, an associated primary malignancy
is uncommon.  However, because of the
high likelihood of malignancy in colon intussusception, caution should be
exercised when performing resection. In this article, the patient referred to
the emergency with ileus findings and the diagnosis of intussusception was
made. Abdominal computed tomography showed small intestine intussusception. The
patient was operated. It was determined that invagination was due to adherent
mass on jejunum wall. İnitial reduction, followed by limited surgical resection
was performed. Postoperative follow-up was uneventful and the patient was
discharged. A pathological report revealed a benign polyp, no malignancy.

The Value of a Sharing Economy, That’s Why We Take Risks: Moderating Effect of the Accommodation Sharing Services Knowledge Calibration
Authors:   The Tourism Sciences Society Of Korea, Oh Jeong-Min , Lee Sang-Ho
Published: November 2019

This study started from a concern about the negative aspects of sharing economic services in the tourism sector. In order to solve this problem, the discussion focused on the inherent value of the sharing economy; in particular, we introduced the concept of knowledge correction, which is the gap between subjective and objective knowledge of users related to sharing services. In addition, considering the different ways of perceiving risk according to individual judgment, we set up a more sophisticated causal model by dividing it into personal risk and social risk. As a result of the analysis, the economic and technological value of the sharing economy lowered the personal risk, and the socio-environmental value decreased the social risk. Also, the moderating effect between technological value and personal risk was verified only in the group with a high level of knowledge correction. Based on the results of these studies, various practical issues are suggested.
Rehabilitation diagnosis in the pathology of the musculoskeletal system using categories of the international classification of functioning. Part 2 (discussion)
Authors: Tsykunov M. B.
Published: November 2019

In accordance with the recommendations of the World Health Organization, the categories listed in the International Classification of Functioning (ICF) should be used to assess the structure, function, activity and participation. In recent years, the assessment of the state of the body is no longer possible without the use of scales, but a large number of them do not always allow specialists to understand each other. The creation of a unified system, which will collect various tools for assessing the patients condition, will provide serious assistance in the work of members of a multidisciplinary team in the process of medical rehabilitation. In addition, it will help in the formulation of rehabilitation diagnosis and in more accurate determination of rehabilitation potential. The dimension of a number of generally accepted scales to describe disorders of the musculoskeletal system does not coincide with the categories of ICE This paper attempts to eliminate this contradiction. To describe a number of disorders that affect the function of the musculoskeletal system and are traditionally used in orthopedics, the category other or not described can be used. In the presented system of evaluation are given equal-weighted scale with the dimension adopted in the ICF. This system can be used as a basis for the preparation of medical rehabilitation programs and evaluation of their effectiveness.
Control of Electric Dipole Moment using Deformation induced by Functionalization of (5, 0) Zigzag Carbon Nanotubes as Gigahertz Oscillators
Authors: Rastani Siroos , Mostaanzadeh Hossein
Published: November 2019

Electric dipole moment (EDM) required for the relative motion of carbon nanotube (CNT) walls in nanoelectromechanical systems (NEMS) such as actuators and oscillators is studied by functionalization. Pristine (5,0) zigzag carbon nanotube with little inherent electric dipole moment (ì) were deformed by adding three -OH functional groups to its end rims. The properties of eight yielded isomers are studied. The Gibbs free energy calculations demonstrate that the eight structures are more stable than pristine CNT. The induced deformation resulted in charge imbalances which developed large electric dipole moments for each case. The values of dipole moments produced for all cases are calculated. The bandgap energy, conductivity, density of state (DOS) and IR spectra of these structures are also computed and analyzed. The study revealed that the location of the -OH positioning (site selectivity) which gives rise to different degrees of deformation has a significant impact on all of the above parameters, especially the magnitude and direction of the electric dipole moment. The functionalization produced large ì of about 6.9 D for 60 carbon atoms nanotube which is higher than in the previous study. Applying an external electric field to the isomers causes the CNTs with large dipole moments to either get attracted or repelled and hence physical movement or oscillation of the nanotube occurs. The frequency of this oscillation is in gigahertz scale. Keywords: Gigahertz oscillator, electric dipole moment, deformation, carbon nanotube, hydroxyl functionalization, site selectivity.
