The aim of this study was to highlight how a combination of TVET and entrepreneurship education can be harnessed to address the problem of unemployment as well as underutilisation of human resources, in Lusaka Province, Zambia, to foster sustainable social economic development. A questionnaire was administered to TVET students. A representative sample of 480 respondents was targeted. Interview respondents included TVET instructors, TVET administrators, TVET government officers, Industry experts and parents of TVET learners. The sample was proportionately shared among the eight districts in Lusaka province. The study was conducted from April 2018 to March 2019. This was a mixed methods research. Quantitative data was analysed using Statistical Package for Social Sciences (SPSS) and qualitative data through thematic approach. The findings indicated that unemployment as well as underutilisation of human resources can be addressed by tapping into the entrepreneurial ambitions of TVET Learners; encouraging, enticing and appealing to students by asking them to consider entrepreneurship as a vocation or career pathway; offering entrepreneurship education to TVET learners; sensitisation and robust rollout of TVET and entrepreneurship education national wide through policy directives; and, developing appropriate curriculum to support the awareness and recognition that TVET learners that acquire entrepreneurship knowledge and skills are potential productive human resource for different industry sectors to drive sustainable economic development.
IMU Mounting Angle Calibration for Pipeline Surveying Apparatus

Odometer and nonholonomic constraints are crucial external aids for inertial navigation systems (INSs) to achieve desirable positioning accuracy for pipeline inspection gauges (PIGs). Exploiting the maximum potential of these constraints requires the accurate knowledge of the inevitably existing misalignment in the attitudes of the inertial measurement unit (IMU) with respect to the host vehicle (i.e., the IMU mounting angle relative to the PIG). In this paper, we address the mounting angle calibration of a PIG without using sophisticated equipment. Instead, the proposed method only requires the PIG to be placed on a simple leveled frame and rotated about its longitudinal axis. In this case, the existing IMU mounting angles will make the IMU’s pitch and heading angles vary with rotation. Closed-form analytic solutions for the IMU’s attitude angles are obtained under this specific condition and show that the magnitude and phase of the IMU’s pitch and heading angles have a linear relation with the corresponding pitch and heading misalignment angles. Then, a method for the misalignment angle estimation is presented based on this principle. Simulations are performed to validate the proposed method and investigate the related error sources that influence the estimation accuracy. The results of the real tests indicate that the mounting angles can be accurately estimated and compensated through this simple and convenient calibration.
A Rectifier Circuit Insensitive to the Angle of Incidence of Incoming Waves Based on a Wilkinson Power Combiner

In this paper, a novel high-efficiency, low-cost, and low-complexity RF-to-dc converter was designed for RF energy harvesting in the 2.4-GHz band. The proposed design has two RF inputs and maintains high efficiency over a wide range of incoming incident wave angles. The circuit is based on a Wilkinson power combiner and has two single-diode rectifiers. One rectifier is connected at the combiner’s output and collects the energy coming from the two inputs. The second rectifier replaces the isolation resistor of the combiner in order to collect the power that would, otherwise, be dissipated in it. The second rectifier is used for recycling the wasted power when the input signals do not have the same phase. The novel RF-to-dc converter was fabricated using the commercially available components and a low-cost FR-4 substrate. A prototype was designed, and its efficiency was optimized for low-power input levels. The measured system efficiency was 16.2% for in-phase input signals with an available input power of −17 dBm. When the relative phase of input signals varied from 0° to 360°, a variation in efficiency between 15.3% and 22% was observed. For an input power of 3 dBm, the efficiency varies from 26% to 39% between 0° and 360° phase difference.
Shaping Tastes and Values Through the Law: Law and Economics Meets Cultural Economics

Abstract This article elaborates on the point made by Guido Calabresi in his recent book “The Future of Law and Economics: Essays in Reform and Recollection”, where he holds that Law and Economics should inform law-makers and policy-makers regarding what tastes and values are more desirable than others. Calabresi invites economists to depart from the approach traditionally embraced in economic analysis holding that “De gustibus non est disputandum”. He proposes instead to dialogue with law-makers in order to openly engage in the promotion of welfare-enhancing tastes and values. My main argument is that recent empirical findings in Economics support Calabresi’s invitation to normatively engage in shaping cultural traits – at least for a specific set of tastes and values.
Price, Product Quality, and Exporter Dynamics: Evidence from China

This article develops a model of heterogeneous firms that endogenously choose prices and product quality to build demand in export markets. New exporters optimally charge relatively low prices and produce low‐quality goods upon entry. Product quality, prices, and sales increase as demand grows. We structurally estimate model parameters using Chinese customs data. The estimated incentive to build future demand reduces average export prices by 0.7% and increases export sales by 4% upon entry. Endogenous demand accumulation causes estimated export prices, product quality, and sales to grow by 2.2%, 12%, and 79%, respectively, over the following five years.
Impact of cooperative learning on teamwork competence

PurposeThe purpose of this paper is to analyze the impact of a classroom application of the cooperative learning (CL) methodology on nine dimensions of business students’ teamwork competence (TC). Design/methodology/approachThe authors used a quasi-experimental pre-post design with a previous cohort as control group (first-year students from the year prior to treatment application), applying treatment to a sample of 228 first-year students in a School of Economics and Business at a Chilean University (114 as treatment and 114 as control). FindingsThe authors’ results show that CL had a positive, significant influence on five dimensions of TC: collective efficacy, planning, goal setting, problem solving and conflict management.Research limitations/implicationsThis paper upholds the importance and effectiveness of CL in developing TC. However, the evidence suggests that the effectiveness of the CL methodology was limited to development and improvement of less complex dimensions of TC. More complex dimensions require a longer period of time to be developed.Practical implicationsThis research is an important contribution to the design and implementation of appropriate methodologies for developing a widely needed area of competence in the workplace, considering its multidimensional nature, whether in academia or business.Originality/valueThis is the first study to seek empirical evidence that would link the CL methodology with TC. In addition, it fills a gap in the literature on the development of TC in its multiple dimensions. It particularly addresses the training of business professionals.
Realizing the Performance Benefits of Workforce Diversity in the U.S. Federal Government: The Moderating Role of Diversity Climate

Conventional wisdom in diversity research holds that biodemographic diversity is harmful to performance, whereas job-related diversity is beneficial to performance. Empirical evidence in this area, however, remains mixed and inconclusive. Due to this inconsistency, scholars have recently called for a search for moderators of the relationship between diversity and performance to expand the theoretical perspectives on organizational diversity. In this context, we examine how biodemographic (gender, race, and age) and job-related (function and tenure) diversity influence organizational performance and how diversity climate as a potential moderator shapes the relationships between the two dimensions of diversity and performance. Using panel data from the U.S. federal government, we find that racial and tenure diversity have positive relationships with organizational performance, whereas functional diversity has a negative relationship. Further analysis reveals that a diversity climate positively moderates the relationship between racial diversity, functional diversity, tenure diversity, and organizational performance. Theoretical and practical implications are discussed.
Synthesis and Structure of Copper Complexes of a N6O4 Macrocyclic Ligand and Catalytic Application in Alcohol Oxidation

Reactions between N6O4 macrocyclic 1,4,19,22,25,40-hexaaza-10,13,31,34-tetraoxa-6,14,27,35(1,4)-tetrabenzenacyclopentacontane (L) and several copper salts (viz. trifuoromethane and toluene sulfonates, nitrate, perchlorate, benzoate, and acetate) led to the formation of dinuclear compounds [Cu2(OSO2CF3)2(DMF)2L](SO3CF3)2 (1), [Cu2(p-OSO2C6H4Me)2L(DMF)2](SO3C6H4Me)2 (2), [Cu2(ONO2)2L(DMF)2](NO3)2 (3), [Cu2(OClO3)2(DMF)2L](ClO4)2 (4), [Cu2(OOCPh)2L(H2O)2](O2CPh)2 (5), and [Cu2(OOCMe)4L] (6), which were characterized by IR, elemental analysis and TG-DTA (thermogravimetric-differential thermal analysis), as well as by single-crystal X-ray diffraction, EPR (electron paramagnetic resonance) spectroscopy, and electrochemical techniques (cyclic voltammetry and controlled potential electrolysis). The molecular structures of compounds 1–6 reveal a considerable conformational flexibility of the ligand L, which allowed its readjustment for the formation of the metal compounds and confirmed the presence of dinuclear endo macrocyclic species. In every case, the L ligand coordinates to each copper cation via three nitrogen atoms, with the remaining coordination positions of the metal square pyramid environment being accomplished by neutral or anionic ligands. The macrocyclic cavities appear to be adequate for the enclosure of a neutral species as proved by compound 6 with 1,4-dioxane. The compounds, in combination with the TEMPO (2,2,6,6-tetramethyl-piperidinyloxyl) radical and in alkaline aqueous solution, act as efficient catalysts in the aerobic oxidation of different alcohols to the corresponding aldehydes (yields up to 99% and TON up 232) after 20 h at 70 °C. In addition, the microwave-assisted solvent-free peroxidative oxidation (by tert-butylhydroperoxide, TBHP) of 1-phenylethanol led to acetophenone yields up to 99% and TOF of 1.1 × 103 after 0.5 h, without any additive.
One-Step Persymmetric GLRT for Subspace Signals

We exploit persymmetric structures to design a generalized likelihood ratio test for detecting subspace signals in homogeneous Gaussian clutter with unknown covariance matrix. The subspace model is employed to account for mismatches in the target steering vector. An exact but finite-sum expression for the probability of false alarm of the proposed detector is derived, which is verified using Monte Carlo simulations. This expression is irrelevant to the clutter covariance matrix, indicating that the proposed detector exhibits a constant false alarm rate property against the clutter covariance matrix. Numerical examples show that the proposed detector has strong robustness to the target steering vector mismatch.
Age and growth of Alburnus mossulensis Heckel, 1843 in Azad Dam Reservoir and Komasi River in Kordestan Province, Iran

The aim of the present study was to estimate the population parameters including length weight relationship (LWR), condition factor (KF), relation condition factor (Kn), age, growth and mortality of Alburnus mossulensis in Azad dam and Komasi river from Kordestan province, Iran. Of 522 specimens, the fork length, total length and weight of A. mossulensis ranged from 70 to 164, 75-175 mm, and 4.3 to 48.1 g and averaged (±SD) 114.0 (±15.97), 127.5 (±25.29) mm and 18.2 (±5.61) g, respectively. The length-weight regression was W=0.0003×FL2.7434 indicating a negative allometric growth. The sex ratio (M:F) was 1:0.49, for adult A. mossulensis (n=134) which differed significantly from the expected 1:1 (P<0.001). The von Bertalanffy growth parameters were estimated as L∞ = 170.3 mm, K = 0.46 yr-1, t0 = -0.59 yr. The instantaneous coefficient of natural mortality was estimated as 0.85 yr-1. The average of condition factor (KF) was 1.27±0.161. Statistically significant differences were found in KF among seasons (P<0.001). There was a significantly negative correlation between FL and KF (r2 = 0.60). The average of relative condition factor (Kn) was 1.06±0.130. In the present study, the Kn of A. mossulensis were close to 1 and greater than 1 in Komasi river and lake, respectively. These results suggested that the well-being of the fish was good in Azad dam region.
A bacterial effector protein prevents MAPK-mediated phosphorylation of SGT1 to suppress plant immunity

Nucleotide-binding domain and leucine-rich repeat-containing (NLR) proteins function as sensors that perceive pathogen molecules and activate immunity. In plants, the accumulation and activation of NLRs is regulated by SUPPRESSOR OF G2 ALLELE OF skp1 (SGT1). In this work, we found that the plant pathogen Ralstonia solanacearum secretes an effector protein, named RipAC, inside plant cells, and it associates with SGT1 to suppress NLR-mediated SGT1-dependent immune responses. RipAC does not affect the accumulation of SGT1, NLRs, or their interaction. However, RipAC inhibits the interaction between SGT1 and MAP kinases, and the phosphorylation of a MAPK target motif in the C-terminal domain of SGT1, which is required for the interaction with NLRs. Such phosphorylation releases the interaction between SGT1 and the NLR RPS2, and contributes to the activation of RPS2-mediated responses. Our results shed light onto the mechanism of activation of NLR-mediated immunity, and suggest a positive feedback loop between MAPK activation and SGT1-dependent NLR activation. Significance Statement The activation of immune receptors that perceive pathogen molecules and initiate immune signaling is tightly regulated. In plants and animals, SGT1 is a major regulator of the accumulation and activation of such receptors, although the mechanisms of this regulation are not well understood. In this work, we found that the plant pathogenic bacteria Ralstonia solanacearum, causal agent of the bacterial wilt disease, secretes an effector protein inside plant cells that suppresses the phosphorylation-dependent activation of SGT1, which in turn inhibits the activation of SGT1-dependent immune receptors. These findings provide new insights into a general mechanism of regulation of immunity, and uncover a new virulence strategy employed by a bacterial pathogen to contribute to disease development.
Risk Sharing, Creditor Diversity, and Bank Regulation

We examine the effectiveness of bank regulation in the light of creditor diversity. Our theory suggests a bank can increase its value by matching the riskiness of its securities and the risk tolerance of its diverse creditors. Even a well-capitalized bank might not eliminate financial fragility in the absence of creditor diversity, because it cannot utilize this matching mechanism. Our simulation finds supporting evidence that capital regulation can improve a bank’s solvency and eliminate financial fragility only when it has diverse creditors. If financial fragility is persistent, we suggest liquidity requirements can mitigate excessive risk-taking.
Physical activity versus nutritional habits of children and teenagers in Ciechanów district

Introduction. One of the most important factors causing the civilisation illnesses is lower physical activity, sedentary lifestyle and unfavourable nutritional habits. Among the young the growing problem is obesity which is the result of the previously mentioned factors. The obesity problem touches 2.5–12% of Polish population. Regular exercises with appropriate strength is considered to be the vital factor in obesity prevention. Aim of the study. To get to know the level of physical activity and nutritional behaviour as well as the link between those among the young form Ciechanów district. Material and methods. The research was conducted with a survey among 899 students of primary, junior and secondary schools both in the town and in the villages. The results were analysed statistically and using hypothesis analysis. Results. Four hundred and fifty seven boys and 442 girls took part in the research. The results show that 28% of the questioned presented an average level of physical activity, 22% satisfactory, 20% low, 16% unsatisfactory. The lowest percentage (14%) was characterised by high level of activity. Among 50% of the questioned represented average nutritional behaviour, as high as 30% low and 9% unsatisfactory. Satisfying habits were shown among 10% of the questioned. The high level of nutritional behaviour was found among only 1% of the surveyed. P R A C A O R Y G I N A L N A
The Development of a Standardized Assessment Framework for Animal Exhibits

Abstract Science centers, zoos, and aquariums share the common goal of engaging visitors in learning about the physical and natural world. Exhibits in zoos and aquariums, however, focus primarily on living organisms. Interactive exhibits are less common in these institutions and this differentiates the way visitors engage with exhibits from that of a typical science center visit. Based on the usefulness of the Visitor-Based Learning Framework (Barriault & Pearson, 2010) as an exhibit assessment tool in science centers, the purpose of this research was to develop a similar tool that assesses the potential learning impact of live animal exhibits in zoos and aquariums. A comprehensive framework of learning-related behaviors was developed and field-tested with a total of 900 visitors. The resulting Visitor-Based Assessment Framework for Animal Exhibits provides zoo and aquarium researchers and practitioners with a valuable tool to assess exhibits through observable behavioral indicators.
INCIDENCE OF CHEMOTHERAPY-INDUCED PERIPHERAL NEUROPATHY IN CANCER PATIENTS IN CLINICAL PRACTICE

Chemotherapy-induced peripheral neuropathy (CIPN) is major neurologic toxic event, with a negative impact on patient’s quality of life (QoL), and frequently requires dose modification or treatment discontinuation. The prevalence of CIPN is expecting to increase as cancer survival continue to improve. The study was conducted on 163 eligible patients with neurotoxic chemotherapy, from the Oncology Department of Clinical Emergency Hospital of Constanța, Romania between January 2017 and June 2018. Patients received a taxane paclitaxel or docetaxel, platinum-based agents cisplatin, carboplatin or oxaliplatin, either as single agent or combination. The incidence of CIPN was 68.09%. The highest incidence of CIPN was associated with paclitaxel (73.14%), and with oxaliplatin (72.22%), followed by cisplatin (30%), and with docetaxel (23.07%). Cumulative dose, regimen schedule, and treatment duration are important risk factors for the development of chemotherapy-induced peripheral neuropathy. Advanced age does not seem to be a significant risk factor of CIPN in our analysis in patients without significant comorbidity.

Community-Based Tourism as a Sustainable Direction in Destination Development: An Empirical Examination of Visitor Behaviors

Community-based tourism is an emerging form of sustainable tourism. Community-based tourism often brings various financial/non-financial benefits to local communities and maximizes sustainability at the local level. The present study was designed to uncover the role of community-based tourism performance in elucidating travelers’ post-purchase decision-making process for sustainable destination products by considering the moderating effect of sense of belonging. A quantitative approach was adopted for the achievement of the research objective. A field survey conducted at community-based tourism destinations was utilized for data collection. The acceptable level of the measurement quality was demonstrated. The results of the structural equation modeling provided empirical evidence that community-based tourism performance significantly affects the formation of travelers’ post-purchase intentions. In addition, the adequacy of the higher-order structure of community-based tourism performance was identified. The community-based tourism performance and intention relationship was also moderated by sense of belonging. With a lack of empirical research about community-based tourism, the findings of this research significantly add to the existing body of knowledge in sustainable tourism.
Redundant and specific roles of cohesin STAG subunits in chromatin looping and transcriptional control

Cohesin is a ring-shaped multiprotein complex that is crucial for 3D genome organization and transcriptional regulation during differentiation and development. It also confers sister chromatid cohesion and facilitates DNA damage repair. Besides its core subunits SMC3, SMC1A, and RAD21, cohesin in somatic cells contains one of two orthologous STAG subunits, STAG1 or STAG2. How these variable subunits affect the function of the cohesin complex is still unclear. STAG1- and STAG2-cohesin were initially proposed to organize cohesion at telomeres and centromeres, respectively. Here, we uncover redundant and specific roles of STAG1 and STAG2 in gene regulation and chromatin looping using HCT116 cells with an auxin-inducible degron (AID) tag fused to either STAG1 or STAG2. Following rapid depletion of either subunit, we perform high-resolution Hi-C, gene expression, and sequential ChIP studies to show that STAG1 and STAG2 do not co-occupy individual binding sites and have distinct ways by which they affect looping and gene expression. These findings are further supported by single-molecule localizations via direct stochastic optical reconstruction microscopy (dSTORM) super-resolution imaging. Since somatic and congenital mutations of the STAG subunits are associated with cancer (STAG2) and intellectual disability syndromes with congenital abnormalities (STAG1 and STAG2), we verified STAG1-/STAG2-dependencies using human neural stem cells, hence highlighting their importance in particular disease contexts.
