Error management in new product development teams

ABSTRACT A few studies have examined error management culture (EMC) in the new product development (NPD) team context. This study investigates the role of EMC on the process outcomes (e.g. team learning (TL) and team creativity (TC)) and project performance (e.g. new product financial performance-NPFP) of NPD projects within the boundary condition of projects’ task complexities (e.g. routines and existing knowledge of tasks). By studying 179 NPD projects, we found that error recognition, psychological safety, and team reward attitude (TRA) create an effective EMC for NPD teams. We also revealed that effective EMC positively impacts TL and TC, and NPFP. Finally, we showed that the routine aspect of task complexity moderates the relationship between EMC and TL. In contrast, the existing knowledge aspect of task complexity does not moderate the relationships between EMC and process and project outcomes.
Jarcho-Levin syndrome term baby with recurrent apnea

Jarcho-Levin syndrome or spondylocostal dysostosis, is a rare axial skeleton anomaly due to mutation in genes involved in somitic segmentation during embryogenesis. We describe a term, newborn baby with antenatally detected midthoracic lordotic deformity with skeletal features of multiple rib anomalies and vertebral defects, but with normal limb lengths. Baby had recurrent apnea requiring non-invasive ventilation and was successfully weaned to room air within 2 days. This syndrome is underdiagnosed and we wish to highlight the simple process involved in making a clinico-radiological diagnosis.
Dispersion Stability And Tribological Properties of Covalently Modified Graphene As A Lubricating Oil Additive

Graphene has excellent mechanical properties with a low coefficient of friction and wear resistance and has a wide range of tribological applications. However, the stable dispersion of graphene in lubricating media is challenging. In this study, graphene is processed via covalent modification. A mild oxidation method selectively grafts carboxyl groups on the edge of the graphene sheet, before connecting tertiary alkyl primary amines through amide bonds. The alkyl chain allows graphene to be stably dispersed in hydrocarbon solvents. FT-IR, XPS, Raman, XRD, SEM, etc. are used to characterize the covalently modified graphene (MG). Dispersion stability experiments showed that MG exhibited stable dispersion in 500N base oil and 15w-40 commercial lubricants, with stability for over 2 months. Tribological test results show that MG in 500N and 15w-40 significantly reduces the friction and wear of steel-steel friction pairs. The stable dispersion of MG in lubricating oil enables the formation of a stable chemical reaction film and graphene physical deposition film during the friction, protects the worn surface, and reduces direct contact, thereby significantly reducing friction and wear.
The national divide: A social representations approach to US political identity

Extending research on US ideological identity as a social identity, this study employs a social representations approach to capture identity meaning as a form of national attachment. Across two studies ( n = 723), we demonstrate that two novel organizing principles of US ideological identity— national reverence (veneration of the nation in the abstract, its symbols, sacred texts, and founding fathers) and individual support (a focus on the progress of individuals and the change required to bring about equality)—significantly predicted ideological self-categorization, 2016 presidential voting, and affective political polarization over and above right-wing authoritarianism and social dominance orientation. The results suggest an integration of national and conservative identities that places US national identity in opposition to liberal identity and to progress and equality, pointing to the divisive employment of national identity in the current political environment.
Energy efficient WSN using hybrid modification PEGASIS with ant lion optimization

Wireless sensor nodes consist of tiny electronic devices that can sense, transmit, and measure data from physical environments such as the field of minter surveillance. These sensor nodes significantly depend on batteries to gain energy which is used to operations associated with communication and computation. Generally, designing communication protocols is feasible to achieve effective usage of these energy resources of the sensor node. Both reported medium access control and routing can achieve energy-saving that supporting real time functionality. This paper emphasizes the use of hybrid modified PEGASIS-Ant lion optimization. Several steps are entailed in this research. First is random distribution of node followed by clustering the map as a circular region. Then, the nodes are connected to the closest node in that region. In consequence, PEGASIS-Ant lion optimization is applied to enhance the connection of the nodes and accomplish the maximum life batter of the sensor. At last, the experiments performed in this work demonstrate that the proposed optimization technique operates well in terms of network latency, power duration and energy’s consumption. Furthermore, the life span of the nodes has improved greatly by 87% over the original algorithm that accomplished a rate of life nodes of 60%.
Astrocyte specific proteins content in the different parts of the rat and mongolian gerbil brain during ontogenesis

Astrocyte-specific proteins are used as markers of astrocytes, particularly in the case of age-related brain dysfunctions and neurodegenerative disorders. However, the data on the content of these proteins in different parts of the brain during ontogenesis are insufficient. in this research, the content of astrocyte spe cific Ca 2+ -binding protein S100B and glial fibrillary acidic protein (GFAP) in cerebellum, thalamus, and hip pocampus of Wistar rats and mongolian gerbils during ontogenesis were determined. Animals were divided by age into four groups (n = 6-10): 1 – newborn (1-day-old); 2 – 30-day-old; 3 – 90-day-old; 4 – 180-day-old. Fractions of soluble and filamentous proteins from the different parts of the brain were obtained by differen tial centrifugation and solubilization with 4m urea. the quantitative levels of S100B and GFAP were deter mined with ELiSA. it was revealed that the content of S100B protein increased significantly by day 180 in all studied parts of the rat and gerbil brain. the content of GFAP both soluble and filamentous forms in the brain of 1 day-old animals was low, but raised significantly after 30 days in all studied parts of gerbil brain, and increased gradually up to 180 days in the rat brain. the magnitude of the increase in the content of the studied astrocyte-specific proteins was shown to be different and to depend on the brain part, postnatal development stage of the animals and their species.
A Frequency Adaptive Scheme Based on Newton Structure of PRRC for LCL-Type Inverter Connected with Weak Grid

Repetitive control (RC) is gradually used in inverters tied with weak grid. To achieve the zero steady-state error tracking of inverter current and compensate the harmonic distortion caused by frequency fluctuation, a frequency adaptive (FA) control scheme for LCL-type inverter connected with weak grid is proposed. This scheme adopts a proportional resonance (PR) controller in parallel with RC (PRRC) to overcome the disadvantages caused by RC inherent one-cycle time delay. A fractional delay (FD) filter based on the Newton structure is proposed to approximate the fraction item of fs/f, where fs and f are sample frequency and grid frequency, respectively. The structure of the proposed FD filter is relatively simple; moreover, coefficients of the filter maintain constant so as not to need online tuning even when grid frequency fluctuates, which decreases the computational burden considerably. The feasibility and effectiveness of the proposed FA control scheme, named as Newton-FAPRRC, are all verified by the simulation and experimental results.
SIRT-1 and CD44 in the saliva of oral squamous cell carcinoma, dysplastic and non-dysplastic oral leukoplakia

Objective: The objective of this study was to investigate the levels of salivary SIRT-1 and CD44 in patients suffering from oral squamous cell carcinoma (OSCC), dysplastic and non-dysplastic oral leukoplakia to assess their potential role as early diagnostic biomarkers for patients with oral leukoplakia and OSCC. Subjects and Methods: sixty patients were recruited from the outpatient clinic of the Department of Oral Medicine and Periodontology, Faculty of Dentistry, Cairo University. Participants were divided into four groups:15 healthy individuals, 15 patients with non-dysplastic leukoplakia, 15 patients with dysplastic leukoplakia, and 15 patients with oral squamous cell carcinoma. Whole unstimulated saliva (WUS) was collected from all participants. Soluble CD44 (solCD44) and SIRT1 were measured using ELISA. Results: CD44 was expressed in all the four study groups with different levels. OSCC showed a statistically significant highest CD44 level. While the control group showed the lowest CD44 level. There was no statistically significant difference between dysplastic leukoplakia and non-dysplastic leukoplakia groups. Similarly, there was no statistically significant difference between non-dysplastic leukoplakia and control groups. OSCC showed the statistically significantly highest SIRT-1 level. There was no statistically significant difference between dysplastic leukoplakia, non-dysplastic leukoplakia, and control groups; all showed statistically significantly lower SIRT-1 levels than the OSCC group. Conclusion: salivary SIRT-1 and CD44 could be used as a screening tool to improve early detection and diagnostic precision of oral leukoplakia and OSCC.
USING FACEBOOK TO PRACTICE WRITING SKILL: WHAT DO THE STUDENTS THINK?

The research aims to find out students’ perceptions toward using Facebook to practice their writing skill. The sample of this study consisted of 20 participants of English major students. The main instrument used in this research was questionnaire which consisted of two sections. The first section was about the students’ general performance on Facebook and its influences. The second was about the influence of Facebook on students’ writing skill. The semi-structured interview was also conducted to support the validity of the data. The result shows that students think that by using Facebook, students can practice their writing by creating English caption and also writing comment on English fan page. Besides that, students can also improve their vocabulary by reading to the captions on the Facebook. Students also can have more idea to write by reading the topic discussed in this social media. It can be concluded that students give positive thought of using Facebook to practice their writing skill.
Interaction between hepatitis B virus infection and the efficacy of camrelizumab in combination with apatinib therapy in patients with hepatocellular carcinoma: a multicenter retrospective cohort study

Background The interaction between hepatitis B virus (HBV) load and anti-programmed cell death (PD)-1 in combination with (+) antiangiogenic therapy remains controversial, especially for hepatocellular carcinoma (HCC) patients. This study sought to explore the effects of HBV load and antiviral therapy on anti-PD-1+ antiangiogenic therapy, and the rate of HBV reactivation during anti-PD-1+ antiangiogenic treatment. Methods We performed a multicenter retrospective cohort study of camrelizumab combined with apatinib (C+A) therapy between January 1, 2019 and January 1, 2021 in patients with unresectable HCC who were seropositive for hepatitis B surface antigen (HBsAg) and received antiviral therapy before C+A involvement. The effects of HBV load and antiviral therapy on C+A and the rate of HBV reactivation during C+A treatment were examined. Results Eighty-six patients were included in the analysis. The patients had a mean age of 55 years, and 72 (83.7%) were male. The objective response rates (ORRs) in patients with low (<2,000 IU/mL) and high (≥2,000 IU/mL) baseline HBV deoxyribonucleic acid (DNA) levels were 34.5% and 32.2%, respectively (χ2=0.046; P=0.829), while the disease control rates (DCRs) were 67.3% and 80.6%, respectively (χ2=1.762; P=0.184). The results of the univariate and multivariate analyses showed that the baseline HBV DNA level did not affect PD. Additionally, none of the 86 patients suffered from HBV reactivation or HBV-related hepatic impairment with continuous antiviral treatment, regardless of nucleos(t)ide analogue (NA) type (F=1.473; P=0.228). Conclusions Baseline HBV loads did not affect the tumor responses of HCC patients receiving anti-PD-1+ antiangiogenic therapy. Thus, HBV reactivation should not be a contradiction for anti-PD-1+ antiangiogenic therapy among patients undergoing continuous and effective antiviral treatment.
Financial reporting, public services and local executives’ re-electability in Indonesia

Abstract This study aims to analyze the effects of audit findings, follow-up of audit recommendations, quality of financial reporting and public services on the incumbent electability. Using subnational elections data in Indonesia in 2015 and 2017, the final sample amounted to 291 observations, which consisted of 11 provincial elections, 55 municipal elections, and 255 district elections. The results showed a negative effect of audit findings on the incumbent electability, as hypothesized. Further findings present the positive influences of the follow-up of audit recommendations, financial reporting quality on incumbent electability. The last result implies the originality of the study in which non-financial performance factor as proxied by the quality of public services in subnational entities in Indonesia are used as the basis for political decision-making by constituents to elect the incumbent or challenger. The practical implications are the need for subnational executives to pay attention to the importance of accounting and auditing practices as well as public service in increasing local community satisfaction and trust. The theoretical findings are insightful in providing mechanisms of government accounting management and the usefulness of public sector information in influencing electoral democracy in local governments in Indonesia. The novelty of this study is in the empirical examination to link auditing practices and its political consequences.
Family Language Policy, Language Maintenance and Language Shift: Perspectives from Ethnic Chinese Single Mothers in Malaysia

Family language policy comprises three components, namely, ideology, practice, and management. Using the conceptual framework of family language policy, this study draws on data from semi-structured interviews and participant observation to explore the role of mothers in the process of language maintenance and language shift in Malaysia. First, it investigates the language choices and ideologies of four Chinese single mothers from Penang that lead to speaking heritage languages and/or dominant languages with their children. Second, it examines the strategies for heritage culture maintenance adopted by these mothers. The study found that two of the mothers speak Chinese heritage languages with their children to reinforce emotional attachment and family cohesion. Conversely, two other mothers face socioeconomic and educational pressures in relation to maintaining Chinese heritage languages, which trigger a shift to using dominant languages such as Mandarin Chinese and English with their children. Nevertheless, all four mothers made efforts in exposing their children to ethnic Chinese cultures. The findings indicate that maintaining heritage languages in the current era has become a challenge for many families in Malaysia while speaking dominant languages is becoming a necessity.
Container lifecycle‐aware scheduling for serverless computing

Elastic scaling in response to changes on demand is a main benefit of serverless computing. When bursty workloads arrive, a serverless platform launches many new containers and initializes function environments (known as cold starts), which incurs significant startup latency. To reduce cold starts, platforms usually pause a container after it serves a request, and reuse this container for subsequent requests. However, this reuse strategy cannot efficiently reduce cold starts because the schedulers are agnostic of container lifecycle. For example, it may ignore soon available containers or evict soon needed containers. We propose a container lifecycle‐aware scheduling strategy for serverless computing, CAS. The key idea is to control distribution of requests and determine creation or eviction of containers according to different lifecycle phases of containers. We implement a prototype of CAS on OpenWhisk. Our evaluation shows that CAS reduces 81% cold starts and therefore brings a 63% reduction at 95th percentile latency compared with native scheduling strategy in OpenWhisk when there is worker contention between workloads, and does not add significant performance overhead.
The impact of lee waves on the Southern Ocean circulation

Lee waves play an important role in transferring energy from the geostrophic eddy field to turbulent mixing in the Southern Ocean. As such, lee waves can impact the Southern Ocean circulation and modulate its response to changing climate through their regulation on the eddy field and turbulent mixing. The drag effect of lee waves on the eddy field and the mixing effect of lee waves on the tracer field have been studied separately to show their importance. However, it remains unclear how the drag and mixing effects act together to modify the Southern Ocean circulation. In this study, a lee wave parameterization that includes both lee wave drag and its associated lee-wave-driven mixing is developed and implemented in an eddy-resolving idealized model of the Southern Ocean to simulate and quantify the impacts of lee waves on the Southern Ocean circulation. The results show that lee waves enhance the baroclinic transport of the Antarctic Circumpolar Current (ACC) and strengthen the lower overturning circulation. The impact of lee waves on the large-scale circulation are explained by the control of lee wave drag on isopycnal slopes through their effect on eddies, and by the control of lee-wave-driven mixing on deep stratification and water mass transformation. The results also show that the drag and mixing effects are coupled such that they act to weaken one another. The implication is that the future parameterization of lee waves in global ocean and climate models should take both drag and mixing effects into consideration for a more accurate representation of their impact on the ocean circulation.
Degradation of Diclofenac Sodium by the UV/Chlorine Process: Reaction Mechanism, Influencing Factors and Toxicity Evaluation

This study examined the reaction mechanism, influencing factors and toxicity of diclofenac sodium (DS) degradation by ultraviolet (UV)/chlorine process. The UV/chlorine was capable of eliminating DS from water. The DS degradation during the UV/chlorine process followed a pseudo-first-order kinetic model that was influenced by chlorine dosage, solution pH, humic acid and bicarbonate concentrations. The free chlorine affects not only DS elimination, but the contribution of various active species as well. Increasing free chlorine dosage from 1 to 7 mg·L-1 increased the first-order rate constant of NaClO, ·OH and reactive chlorine species (RCS) from 0.00063, 0.00328 and 0.00203 min−1 to 0.00233, 0.0101 and 0.0974 min−1, respectively, and increased the contribution of RCS from 8.20% to 75.71%, while the contribution of UV, NaClO, and ·OH were declined from 76.02%, 2.54% and 13.24% to 14.63%, 1.81%, and 7.85%, respectively. The contribution of RCS became increasingly prominence with the increment of free chlorine dosage. The kobs,UV/chlorine,DS value decreased from 0.0797 to 0.0445 min-1 as pH increased from 5.0 to 8.0. The presence of bicarbonate and natural organic matter both exerted an inhibitory effect on DS degradation. Eleven intermediate products were identified and the degradation pathway involved C-N cleavage, condensation, hydroxylation, and decarboxylation was proposed. The UV/chlorine process effectively reduced acute toxicity and was superior to chlorination. The genotoxicity induced by a chlorinated solution treated by the UV/chlorine process exhibited negative genotoxicity. These results show that the UV/chlorine process is capable for the degradation and detoxification of DS.
Crystallization and structural properties of a family of isotopological 3D-networks: the case of a 4,4′-bipy ligand–M2+ triflate system

Flexible, stimuli-responsive metal–organic frameworks (MOFs) are very attractive as functional materials due to their wealth of tuneable structural and physical properties. Such compounds are commonly investigated by powder X-ray diffraction (PXRD) or spectroscopy techniques, as in most cases single-crystal X-ray diffraction experiments are not suitable due to process-induced twinning and loss of crystallinity. We re-synthesized a Cu-based flexible porous 3D 2-fold interpenetrated coordination polymer (CUT-1) that bears two kinds of square microporous channels to allocate guest solvent molecules that are lost spontaneously. By crystallizing CUT-1 in a gel medium we were able to increase the mechanical stability and resistance to dehydration of the crystalline samples making it possible to characterize the solvent desorption process at various stages by time-resolved single-crystal X-ray diffraction. The possibility of using other metal ions, such as Cd(II) and Fe(II), to produce a coordination network isostructural with the copper one was also explored in order to highlight the importance of the chemical nature of the metal centre in governing the final structure of the equilibrium product.
A Model of Position Effects in the Sequential Lineup

What is the effect of placing the suspect in different positions in a sequential lineup? To explore this question, we developed and applied a model called the Independent Sequential Lineup model which analyzes a sequential lineup in terms of both identification position, the position at which the witness identifies a lineup item as the target, and target position, the position at which the target or suspect appears. We conducted a large-scale online eyewitness memory experiment with 7,204 participants each of whom was tested on a 6-item sequential lineup with an explicit stopping rule. The model fit these data well and revealed systematic effects of lineup position on underlying discriminability and response criteria. We also fit the model to data from a similar pair of experiments conducted recently by Wilson, Donnelly, Christenfeld and Wixted (2019; Journal of Memory and Language, 104, 108-125) both with and without application of a stopping rule. In all data sets, if a stopping rule is applied, underlying discriminability was found to be constant, or to increase slightly, across target position. In the absence of a stopping rule, discriminability was found to decrease substantially. We also observed a substantial increase in response criteria following presentation of the target. We discuss the implications of these findings for current theories of recognition memory and current applications of the sequential lineup in different jurisdictions.
