A Sector Wheel Approach to Understanding the Needs and Barriers to Services among Homeless-Experienced Veteran Families

Background: Veteran family homelessness is a significant issue, yet little is known about the needs and barriers to services of veteran families experiencing homelessness. This qualitative study examined the experiences, needs, and barriers to services among homeless-experienced veteran families to inform providers for this important population. Methods: Twenty-five semi-structured interviews were conducted from February through September 2016 with 18 veteran parents with a recent history of homelessness (9 mothers, 9 fathers), and 7 homeless service providers throughout Los Angeles County. The “Sector Wheel for Under-Resourced Populations” data elicitation approach was used to conduct the interviews, which allowed the participant to guide the interview by discussing different sectors of a family's life affected by homelessness. The interviews were audio-recorded, transcribed, and themes were coded with Atlas.ti. Results: Interviews revealed parenting stress and worsening family mental health during homelessness. Participants described barriers to navigating housing, social, and health services with children, including not knowing where to seek help, difficulty connecting to health and social services in the community, and a lack of family-focused services. Parents encountered discrimination by landlords and lack of access to permanent housing in safe neighborhoods. Conclusions: Findings demonstrate a need for delivering family-centered and comprehensive services to homeless-experienced veteran families that recognize the multifaceted needs of this population. Advocacy initiatives are needed to address discrimination against veterans experiencing family homelessness and increase access to affordable permanent housing in safe neighborhoods for families.

Managerial leadership within Vietnam’s transition

Vietnam’s transition towards a market orientation has generated many changes in cultural values, competing demands and diverse expectations related to managerial leadership. This study makes a timely contribution to both theory and practice by exploring what makes effective leadership in the Vietnam’s context. Taking into account ‘universalistic’ and ‘contextual’ perspectives, this study addresses two research questions regarding the characteristics of indigenous leadership in Vietnam and its interaction with coexisting cultural values and norms in the country’s transition. These research questions were examined based on 48 qualitative interviews conducted across a broad spectrum of domestic-private, foreign-invested and state-owned companies. Study findings enrich the understanding of indigenous interpretations of the leadership phenomenon and provide support for context-specific examinations of general management leadership issues in transitional economies.
Strain, torsion and refractive index sensors based on helical long period fibre grating inscribed in small-core fibre for structural condition monitoring

This study is intended to develop long period fibre grating sensors for potential applications in environmental and durability monitoring of coastal structures. High-quality helical long period fibre gratings (HLPFGs) are inscribed in different types of small-core single mode fibre (SMF) by use of hydrogen-oxygen flame heating technique. A detailed investigation of the effect of core diameter on their transmission spectrum and optimum length of the HLPFG has been pursued. A longer length is required to achieve the same coupling attenuation in a smaller-core SMF than that of a larger-core fibre. The strain, torsion and refractive index (RI) properties of the HLPFG is investigated experimentally to develop a high-sensitivity sensor. The experimental results show that the strain sensitivity could be enhanced by means of employing a larger-core diameter SMF. Moreover, the HLFPGs are also sensitive to the torsion and external RI. Hence, such HLFPGs have great potential for sensing applications.
Does it pay to bribe? The influence of bribery on new venture disbanding in China

This research extends bribery research toward entrepreneurial theory and practice by examining how bribery impacts new venture disbanding in China. Existing research suggests that bribery may enhance firms’ competitive advantage; however, building off of resource-based view and taking into consideration the institutional context in China, the current study proposes that firm bribery activity hurts new ventures by increasing the hazard of venture disbanding. Further, guided by resource dependence theory, this study examines how local economic development and organizing activity moderate the relation between bribery and disbanding. In particular, it is proposed that when local economic development is suffering, or when firms are not engaging in appropriate organizing activities, bribery will lead to higher chance of new venture disbanding. Data from Chinese entrepreneurs support these hypotheses.
Sonochemical effect induced by hydrodynamic cavitation: Comparison of venturi/orifice flow geometries

This study presents comparative assessment of four cavitation devices (3 venturis and an orifice) in terms of cavitational yield. A 4-fold approach was adopted for assessment, viz. CFD simulations of cavitating flow, simulations of individual cavitation bubble dynamics, high speed photographs of cavitating flow and model reaction of potassium iodide oxidation. Influence of design parameters of cavitation devices on nature of cavitation produced in the flow was studied. Number density of cavitation bubbles in the flow and interactions among bubbles had critical influence on cavitation yield. Orifice gave the highest cavitational yield per unit energy dissipation in flow (despite lower working inlet pressure) due to low density of cavitation bubbles in flow. On contrary, occurrence of large cavitation bubble clouds in venturi flow had adverse effect on cavitational yield due to high interactions among cavitation bubbles resulting in inter-bubble coalescence and recombination of oxidizing radicals generated from cavitation bubbles.

Synthesis, characterization and antiurease activities of a novel Mannich base 1-[(4-methoxyphenyl)(2-methylidenecyclohexyl)methyl]pyrrolidine (MMP) and its complexes with Cu (II), Ni (II), Co (II), and Fe (II) ions

ABSTRACT Mannich base 1-[(4-methoxyphenyl)(2-methylidenecyclohexyl)methyl]pyrrolidine (MMP) was synthesized by condensing cyclohexanone, 4-methoxybenzaldehyde, and pyrrolidine together using ethanol as solvent. The synthesized ligand was further made to react with CuCl2, NiCl2, CoCl2, and FeCl2 to afford their respective complexes. Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1H NMR), carbon thirteen nuclear magnetic resonance (13C NMR), thermogravimetric analysis (TGA), and mass spectrometry (MS) were used to characterize the ligand and its complexes. The proposed geometries of the complexes were established on the basis of metal–ligand ratio through atomic absorption spectroscopy (AAS). The synthesized compounds were analyzed for their antiurease potential. Mannich base showed moderate antiurease activity with an IC50 value of 224.83 ± 0.84 μM. Complexes with Ni (II) and Fe (II) exhibited potent antiurease activity (4.41 ± 0.003, 5.21 ± 0.003 μM, respectively) while the Co (II) complex showed excellent (46.52 ± 0.05 μM) antiurease activity and poor antiurease activity was shown by the Cu (II) complex (424.32 ± 0.96 μM) as compared with the standard thiourea (21.25 ± 0.15 μM). Docking studies of the ligand were also consistent with the experimental results.
Oregano oil use in broiler diet increases accumulation of carvacrol and thymol in breast meat

Oregano oil is an aromatic used in poultry industry as a natural additive. This research was designed to quantify thymol and carvacrol in chicken breast meat. In total, 320 Broilers were fed on basal corn soybean meal diet contained crude soybean oil (CSO) or acidulated soybean oil (ASO) as a resource of energy with or without oregano oil (OO). Identification and measurement of compounds in meat was performed by gas chromatography (GC) and mass spectrometry (MS). Data obtained were transformed and analyzed parametrically, a significant increase of thymol and carvacrol was found in chicken breast meat supplemented with oregano oil ( p < 0.05). Breast meat of broilers fed with oregano oil and CSO accumulated more thymol and carvacrol: 333% and 366%, respectively. Breast meat of broilers fed with oregano oil and ASO accumulated thymol, but more carvacrol: 552% and 648% respectively, compared with control. In conclusion, oregano oil supplementation in diet increased deposition of thymol and carvacrol in broiler meat.
Control and stability analysis of DC microgrid system including wind and solar generation sources and grid‐connected voltage source converter

The study system in this paper is a grid‐connected DC microgrid system comprising PV and wind generation sources, resistive and constant power loads (CPLs), and grid‐connected VSC. The VSC keeps the DC link voltage constant, and the wind and PV sources operate in maximum power point tracking (MPPT) mode, and thus, the DC–DC converters related to these sources act such as controlled current sources behaving similar to negative CPLs. The study system suffers from the stability under high CPL penetration and weak AC grid conditions. Hence, this paper investigates and enhances the system stability under both high CPL penetration and weak AC grid conditions. To do this, modal and small‐signal stability analysis of the system is carried out, and then, as the main findings, impacts of the wind and PV sources output powers, CPL power, and AC grid short‐circuit power on the system stability are studied. Next, as the main contribution, VSC control structure is modified by adding stabilizing signals to enhance the system stability under high CPL penetration, reduced output powers of the wind and PV sources, and weak AC grid conditions. At the end, several simulation results verify the theoretical results at different conditions.
Are People Willing to Tell Pareto White Lies? A Review and New Experimental Evidence

We explore whether individuals are averse to telling a Pareto white lie—a lie that benefits both themselves and another. We first review and summarize the existing evidence on Pareto white lies. We find that the evidence is relatively limited and varied in its conclusions. We then present new experimental results obtained using a coin-tossing experiment. Results are provided for both the UK and China. We find evidence of willingness to tell a partial lie (i.e., inflating reports slightly) and high levels of aversion to telling a Pareto white lie that would maximize payoffs. We also find no significant difference between willingness to tell a Pareto white lie and a selfish black lie—a lie that harms another. We find marginal evidence of more lying in China than the UK, but the overall results in the UK and China are very similar.
An Agent Based Model of a Thinly Traded Land Market in an Urbanizing Region

: We have developed a model of a multi-period agent-based land market based on the theory of thinly traded land markets. This new model builds upon the stylized fact that land demand (supply) decreases (in-creases) across the urban-rural gradient. The effect of heterogeneous amenities are also included in the model. We simulated the model for a growing urbanizing region and investigated the evolution of land development patterns. We found that this simple model can replicate/reproduce many interesting observed features. For instance, scattered development can emerge in transitory periods due to the land demand (supply) decreases (increases) over the urban-rural gradient. Furthermore, increases in transportation costs and the number of in-migrants tend to decrease both the intensity and persistence of scattered development. area, but that it disappears as the region becomes more populated and competition for land increases. The simulation results show that the intensity and persistence of scattered development are systematically related to key economic factors of the model, like market competition condition, transportation costs, migration rate.

Review of efficiency enhancement techniques and linearization techniques for power amplifier

Power amplifier is one of the most important module of transceiver design. Linearity and efficiency are the two main areas of improvement in power amplifier design. Fifth generation (5G) mobile communication is one of the most important application of power amplifier, which require power amplifiers that are extremely linear and efficient. In this paper, review of different efficiency enhancement and linearization techniques has been undertaken. Basic architecture, advantages, and challenges of efficiency enhancement techniques—outphasing, Doherty, and envelope tracking—have been discussed. Linearization techniques—feedback, feedforward, and predistortion—have also been discussed in this paper.
A Multi-Tier Security Analysis of Official Car Management Apps for Android

Using automotive smartphone applications (apps) provided by car manufacturers may offer numerous advantages to the vehicle owner, including improved safety, fuel efficiency, anytime monitoring of vehicle data, and timely over-the-air delivery of software updates. On the other hand, the continuous tracking of the vehicle data by such apps may also pose a risk to the car owner, if, say, sensitive pieces of information are leaked to third parties or the app is vulnerable to attacks. This work contributes the first to our knowledge full-fledged security assessment of all the official single-vehicle management apps offered by major car manufacturers who operate in Europe. The apps are scrutinised statically with the purpose of not only identifying surfeits, say, in terms of the permissions requested, but also from a vulnerability assessment viewpoint. On top of that, we run each app to identify possible weak security practices in the owner-to-app registration process. The results reveal a multitude of issues, ranging from an over-claim of sensitive permissions and the use of possibly privacy-invasive API calls, to numerous potentially exploitable CWE and CVE-identified weaknesses and vulnerabilities, the, in some cases, excessive employment of third-party trackers, and a number of other flaws related to the use of third-party software libraries, unsanitised input, and weak user password policies, to mention just a few.
Teams Do Inflict Costly Third-Party Punishment as Individuals Do: Experimental Evidence

Initiated by the seminal work of Fehr and Fischbacher (Evolution and Human Behavior (2004)), a large body of research has shown that people often take punitive actions towards norm violators even when they are not directly involved in transactions. This paper shows in an experimental setting that this behavioral finding extends to a situation where a pair of individuals jointly decides how strong a third-party punishment to impose. It also shows that this punishment behavior is robust to the size of social distance within pairs. These results lend useful insight since decisions in our everyday lives and also in courts are often made by teams.
Cross Inhibition of MPK10 and WRKY10 Participating in the Growth of Endosperm in Arabidopsis thaliana

The product of double fertilization produces seed, which contains three components: triploid endosperm, diploid embryo, and maternal seed coat. Amongst them, the endosperm plays a crucial role in coordinating seed growth. Mitogen-activated protein kinase (MAPK) cascades are conserved in eukaryotes and involved in signal transduction of plant development. MPK3, MPK6, and MPK10 form a small group of MPKs family in Arabidopsis thaliana. MPK3 and MPK6 are extensively studied and were found to be involved in diverse processes including plant reproduction. However, less is known about the function of MPK10. Here, we found WRKY10/MINI3, a member of HAIKU (IKU) pathway engaging in endosperm development, and MPK10 is high-specifically expressed in the early developmental endosperm but with opposite gradients. We further proved that MPK10 and WRKY10 cross-inhibit the expression of each other. The inhibition effect of MPK10 on gene expression of WRKY10 and the downstream targets is supported by the fact that MPK10 interacts with WRKY10 and suppresses the transcriptional activity of WRKY10. Constantly, mpk10 mutants produce big seeds while WRKY10/MINI3 positively regulate seed growth. Altogether, our data provides a model of WRKY10 and MPK10 regulating endosperm development with a unique cross inhibitory mechanism.
Bacterial Gamma-Glutamyl Transpeptidase, an Emerging Biocatalyst: Insights Into Structure–Function Relationship and Its Biotechnological Applications

Gamma-glutamyl transpeptidase (GGT) enzyme is ubiquitously present in all life forms and plays a variety of roles in diverse organisms. Higher eukaryotes mainly utilize GGT for glutathione degradation, and mammalian GGTs have implications in many physiological disorders also. GGTs from unicellular prokaryotes serve different physiological functions in Gram-positive and Gram-negative bacteria. In the present review, the physiological significance of bacterial GGTs has been discussed categorizing GGTs from Gram-negative bacteria like Escherichia coli as glutathione degraders and from pathogenic species like Helicobacter pylori as virulence factors. Gram-positive bacilli, however, are considered separately as poly-γ-glutamic acid (PGA) degraders. The structure–function relationship of the GGT is also discussed mainly focusing on the crystallization of bacterial GGTs along with functional characterization of conserved regions by site-directed mutagenesis that unravels molecular aspects of autoprocessing and catalysis. Only a few crystal structures have been deciphered so far. Further, different reports on heterologous expression of bacterial GGTs in E. coli and Bacillus subtilis as hosts have been presented in a table pointing toward the lack of fermentation studies for large-scale production. Physicochemical properties of bacterial GGTs have also been described, followed by a detailed discussion on various applications of bacterial GGTs in different biotechnological sectors. This review emphasizes the potential of bacterial GGTs as an industrial biocatalyst relevant to the current switch toward green chemistry.
TOX Acts as a Tumor Suppressor by Inhibiting mTOR Signaling in Colorectal Cancer

The treatment and prognosis of advanced colorectal cancer (CRC) remain a challenging clinical research focus. Here, we describe a new CRC tumor suppressor and potential therapeutic target: thymocyte selection associated high mobility group box (TOX) protein. The expression of TOX was lower in CRC than para-CRC. With the increase of tumor stage, TOX expression decreased, indicating the presence of TOX relates to better overall survival (OS). TOX suppressed the mechanistic target of rapamycin kinase (mTOR) signaling to inhibit cell proliferation, migration, invasion, and change the epithelial-mesenchymal transition (EMT) process. In addition, TOX promoted apoptosis. As tumor mutation burden and tumor microenvironment play vital roles in the occurrence and development of tumors, we analyzed the TOX expression in the immune microenvironment of CRC. The high TOX expression was negatively correlated with TumorPurity. Moreover, it was positively related to ImmuneScore, StromalScore, microsatellite instability (MSI) status, and Consensus Molecular Subtypes (CMS) 3 typing. Based on gene set enrichment analysis (GSEA), the reduced expression of TOX activated mTOR. We found rapamycin, a mTOR inhibitor, partly inhibited cell proliferation, invasion, and migration in shTOX HCT116 cells. Lastly, TOX suppressed tumorigenesis and lung metastasis of CRC in vivo. Rapamycin alone or combined with PD1 inhibitor is more effective than PD1 inhibitor alone in a tumor model. Taken together, these findings highlight the tumor-suppressive role of TOX in CRC, especially in MSI CRC, and provide valuable information that rapamycin alone or combined with PD1 inhibitor has therapeutic potential in CRC.
How Finnish and Portuguese Parents’ Implicit Beliefs About Learning Actualize at Home

The purpose of this qualitative study was to explore parental engagement in the home learning environment, and parents’ implicit beliefs about learning underlying such engagement. Nineteen parents of school children between 7 and 12 years old were interviewed in two different cultural contexts, Finland (N = 10) and Portugal (N = 9). The interviews were subjected to inductive and deductive content analysis. Forms of parental engagement at home were similar in both countries, divided between two main categories: engagement with their child’s holistic development and engagement with the child’s schooling process. Parental narratives about engagement were, for the most part, embedded in a growth mindset (or an incremental meaning system). The most common actualizations of engagement included considering the child’s learning contexts and emotions; encouraging effort, persistence and practice; approaching difficulties as a natural part of learning and suggesting strategies for overcoming them. Parental practices of engagement were combined with the actualization of their implicit beliefs to create parental engagement–mindset profiles. Twelve parents were classified as having a growth mindset to support the child’s holistic development profile, and the other seven were distributed amongst the three remaining profiles. The study contributes to the growing interest on the association between parental engagement and their learning-related implicit beliefs, giving clear first-person illustrations of how both occur and interact in the home learning environment. Implications for practice are discussed.
