Optimal Exploitation and Management of a Highly Variable Fishery: Preliminary Results from the Falkland Islands Loligo Squid Fishery

Loligo gahi (Patagonian longfin squid) has been the target of a major trawl fishery in the waters around the Falkland Islands since the early 1980s. The catch of this short-lived species can fluctuate markedly due to variation in seasonal recruitment. Ex-vessel prices of loligo are also variable due to international market conditions and variation in the average size of squid landed. Given the importance of the fishery to the Falkland Islands, there is considerable interest in exploring opportunities to improve the value of the fishery through alternative harvest strategies, industry involvement in downstream market sectors, and by establishing rights-based management regimes. To evaluate these opportunities, cost and market data were collected. Hedonic output price and input cost models were empirically estimated and used to determine revenues and profits for three years from 1999 through 2001. Results show that the industry as currently structured has been relatively profitable at moderate stock and recruitment levels but may be unprofitable at low stock and recruitment levels. The implications of these findings for developing an integrated bioeconomic model of the fishery are discussed.
A Study on Pygmalion Effect: A Case of Academic Training in a Military Unit

The purpose of this study is to investigate the impact of leaders' expectations and behavior on subordinates' performance in order to validate the theory of Pygmalion effect in a training unit of Pakistan Air Force. For this research, questionnaires have been adopted from the study of (Hsu, et al., 2009). These questionnaires include three variables namely: Perceived Behavior of Leader (independent variable), Performance of Subordinate (dependent variable) and Self-Efficacy (mediating variable). The trainers of a PAF training unit are the leaders and the Junior Commissioned Officers (JCOs) trainees are the subordinates. The questionnaires of Perceived Behavior of Leader and Self-Efficacy have been filled by 150 subordinates while the questionnaire on their Performance has been filled by the leaders. The questionnaire has shown high internal consistency. The findings also provide support for the basic relationship proposed in the traditional Pygmalion model. Results have suggested that when the trainers have been supportive, collaborative, resourceful and encouraging then the trainees have shown high self-belief resulting in high performance. The results support the notion that leaders trigger the sense making of the subordinates which is required for better performance. The study has been conducted in a military environment; therefore, the results of this study may vary in an open environment like universities and colleges. The results are limited to JCOs only, however the same study can provide different perspective for PAF Officer or military personnel of sister services. The results can be helpful to the authorities in acting more precisely to increasing the performance of the trainees through Pygmalion effect. The study can provide a basis for future research in the field of military training. Keywords: Pygmalion Effect, Self Efficacy, Perceived Behavior of Leader, Junior Commissioned Officers, Pakistan Air Force.
Cascade Reliability of Stress-Strength system when Strength follows mixed Exponential distribution

Abstract: Cascade reliability model is a special type of StressStrength model. The nCascade system is a hierarchical standby redundancy system, where the standby component taking the place of failed component with decreased value of stress and independently distributed strength. In assessing system reliability it is first necessary to define and categorize different modes of system failures. The individual distributions that are combined to form the mixture distribution are called mixer components. In this paper it has been discussed that the reliability of ncascade system when strength follows mixed exponential distribution and stress follows exponential distribution.
Position control and vibration suppression of a flexible overhead crane system

Trolley positioning and payload swinging control problem of a flexible overhead crane system is addressed in this paper. The system’s equations of motion that couple the crane’s cable and actuators dynamics are derived via extended Hamilton’s principle. The control signal is designed based on the Lyapunov direct method and backstepping control. The stability of the closed loop system is proven. Numerical simulations are included to demonstrate the effectiveness of the proposed control.
Quantifying the Sources of Firm Heterogeneity

We develop and structurally estimate a model of heterogeneous multiproduct firms that can be used to decompose the firm-size distribution into the contributions of costs, “appeal” (quality or taste), markups, and product scope. Using Nielsen bar-code data on prices and sales, we find that variation in firm appeal and product scope explains at least four fifths of the variation in firm sales. We show that the imperfect substitutability of products within firms, and the fact that larger firms supply more products than smaller firms, implies that standard productivity measures are highly dependent on implicit demand system assumptions and probably dramatically understate the relative productivity of the largest firms. Although most firms are well approximated by the monopolistic competition benchmark of constant markups, we find that the largest firms that account for most of aggregate sales depart substantially from this benchmark, and exhibit both variable markups and substantial cannibalization effects.
Characterization of ZnSe Nanolayers by Spectroscopic Ellipsometry

Single layers of ZnSe with thicknesses of 30, 40, 50, 70 and 100 nm are deposited at room substrate temperature by thermal evaporation of ZnSe powder in vacuum. The layers surface morphology has been investigated by atomic force microscopy. Structural characterization by the Raman scattering measurement revealed the existence of randomly oriented crystalline ZnSe particles in all layers, and the presence of amorphous phase in layers thinner than 100 nm. The ellipsometric measurements were performed in the range from 1.5 to 5 eV at room temperature in air. To interpret the experimental results, the Bruggeman eective medium approximation of dielectric function of ZnSe layers has been used, representing the layers as dierent mixtures of crystalline ZnSe (c-ZnSe), amorphous ZnSe (a-ZnSe), and voids. The assumption of polycrystalline ZnSe layers modeled as mixture of porous c-ZnSe (with volume fraction of voids … 0:17) and a-ZnSe gives the best fit of ellipsometric experimental data. Single layer thicknesses similar to those expected from preparation conditions have been obtained by this fitting procedure. It has been also found that decrease in the layer thickness causes an increase of the volume fraction of a-ZnSe. Thus, c-ZnSe/a-ZnSe ratio, porosity and layer thickness obtained by spectroscopic ellipsometry, provides useful information about crystallinity and micro-/nanostructure of ZnSe nanolayers.
Tilburg University Non-deterministic attribute selection in reference production

In producing identifying descriptions, speakers often overspecify and manifest preferences for certain attributes. However, current computational models which incorporate this observation tend not to make precise predictions about when and how much speakers do this. The present paper proposes and evaluates two alternative models, based on the results of a new experiment. Unlike current models, the new ones are nondeterministic and seek to make precise quantitative predictions about the extent to which speakers overspecify.
Embedded design consideration for the implementation of food intake monitoring system:validated using LabVIEW software

Memory loss is a common problem found among old people, the person may forget mealtime altogether due to memory loss. This paper proposes an idea for a monitoring system which will monitor the old people food intake from a remote place and generate an alarm locally. A wearable system is designed usingpiezoelectric sensor that will sense the trachea movement during food ingestion and produces an output signal with variations in the frequencies over time. Based on the detected frequency, food type is classified. Food classification algorithm is depends on Time-Frequency analysis of the piezoelectric output and the wearable design transmits the signals to PC via Bluetooth module. The received signal is processed by LabVIEW and accuracy is tested.
Exploration and exploitation: Do actual behaviors match individuals' perceptions?

Research on contextual ambidexterity assumes that an organizationOs capacity to pursue simultaneously exploration and exploitation leverages on organizational solutions encouraging a balance between these two learning orientations. However, limited attention has as yet been devoted to the investigation of contextual ambidexterity at the individual level of analysis. Starting from this gap, this paper addresses the following research questions: How do individuals perceive the learning orientation required of them by their job? Do individualsO behaviors match their perceived orientation? How can the matching/mismatching between perceptions and behaviors be explained? To address these issues a multiple case study of 16 managers and assistants in the R&D and Sales units of four medium enterprises located in Northeast Italy was carried out. Our findings show that perceptions and actual behaviors, as dimensions of the personal ambidexterity, are independent of each other and can determine a misalignment with the organizational ambidexterity. Accordingly, we propose a conceptual and operational framework, in which the interplay among individual factors such as prior work experiences and personal characteristics, through the mechanism of role stressors, mold both dimensions of personal ambidexterity.
Measurements of Higgs boson production and properties in the ZZ decay channel using the CMS detector

Properties of the Higgs boson are measured in the H→ ZZ→ 4` (`= e,μ) decay channel. A data sample of proton-proton collisions at a center-of-mass energy of 13 TeV is used, corresponding to an integrated luminosity of 41.5 fb−1 recorded in 2017 by the CMS detector at the LHC. The signal-strength modifier μ , defined as the ratio of the observed Higgs boson rate in the H→ ZZ → 4` decay channel to the standard model expectation, is measured to be μ = 1.10+0.19 −0.17 at mH = 125.09 GeV, the combined ATLAS and CMS measurement of the Higgs boson mass. The signal-strength modifiers for the main Higgs boson production modes are also constrained. Combination with data recorded in 2016 by the CMS detector at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 35.9 fb−1 is reported. All results are found to be compatible with the standard model predictions.
Title : Process Development and J 1 odeliIf Thin

approved: John F 'jim Transistors. A class of high-performance thin-film transistor (TFT) channel materials has emerged involving oxides composed of heavy-metal cations (HMCs) with (n-1)d'°ns° (n4) electronic configurations. This thesis is devoted to the pursuit of three topics involving the development of these materials for TFT applications: modeling TFT currentvoltage characteristics, an exploratory method for the evaluation of multicomponent HMC oxide systems, and passivation of zinc tin oxide TFTs. The first topic involves generic, modeling of the current-voltage characteristics of a TFT. Initially, a general equation, the conductance integral equation, is derived. This equation expresses the drain current as an integral of the channel conductance with respect to the gate voltage. The utility of the conductance integral equation is demonstrated via derivation of the square-law model current-voltage equation, which constitutes the basic TFT model. Finally, a comprehensive current-voltage equation expressing 'D for a depletion-mode field-effect transistor is derived from the conductance integral equation. The second topic relates to the development of a novel deposition methodology which is employed for exploratory development of HMC oxides for channel layers in TFTs. The method involves sequential RF sputter deposition of thin, single cation oxide layers and subsequent post-deposition annealing in order to obtain a multi-component oxide thin film. The viability of this rapid materials development Redacted for Privacy methodology is demonstrated through the realization of high-performance TTFTs with channel layers composed of combinations of zinc oxide/tin oxide, and tin oxide/indium oxide. The third topic concerns the development of a methodology for the passivation of bottom-gate TFTs utilizing zinc tin oxide as the channel layer and silicon dioxide as the passivation layer. This methodology involves annealing of the TFT after channel layer deposition and an additional anneal after thermal evaporation of a silicon dioxide passivation layer. Passivated zinc tin oxide TFTs possess electrical characteristics equivalent to those of unpassivated, air-exposed devices. In contrast, TFT electrical performance is dramatically degraded if a zinc tin oxide TFT is covered with a dielectric layer and does not undergo both types of anneal. In addition to silicon dioxide, successful passivation of zinc tin oxide TFTs is accomplished using thermally evaporated calcium fluoride, germanium oxide, strontium fluoride, or antimony oxide as passivation dielectrics. ©Copyright by David Hong June 3, 2005 All Rights Reserved Process Development and Modeling of Thin-Film Transistors.

A modi ed test for detecting in uential decision-making units in data envelopment analysis

In data analyses based on a deterministic or stochastic approach, using pre-study is very important to identify observations that are not suitable to data in general. Among such observations, those that have a high tendency to change results negatively are called in uential observations. In this paper, we propose a new method to identify in uential observations in Data Envelopment Analysis (DEA). Our method is a modi ed version of the one proposed by Pastor et al. [12]. Both methods are compared by using two well-known data sets and the outcomes are discussed. A comparative analysis indicates that our method is an e ective alternative to the Pastor et al. [12] method to identify in uential observations in DEA.
In Vitro Regeneration via Somatic Embryogenesis of Schizozygia Coffeoides Baill (Mpelepele)

Schizozygia coffeoides (Mpelepele) is an endangered medicinal shrub with substantial antifungal and antibacterial properties. The sustainable utilization of this shrub is hindered by its limited regeneration potential since there exists no protocol for In vitro regeneration of not only this plant but the entire Apocynaceae family. The aim of this study was to develop an appropriate sterilization and regeneration protocol for In vitro regeneration of S. coffeoides using leaf discs, with the specific aims of determining the best NaOCL concentrations for explant sterilization as well as the appropriate plant growth hormone combinations for development of embryogenic calli, shoot development and rooting. Sterilization was optimized using NaOCl at the concentrations of 5.2mM, 7.8mM, 10.4mM and 13mM at exposure times of 10, 15, 20 and 25 minutes. The different concentrations of NaOCl had a significant effect on the survival of explants to sterilization (P=<0.0001), with the lower concentrations (5.2mM and 7.8mM) showing high levels of explant contamination and high concentration (13mM) leading to explant scotching. Similarly, the time explants were subjected to the sterilization substances was also found to significantly affect their ability to survive the sterilization process (P=0.0027). The best time and NaOCl concentration interaction for the sterilization of leaf explants was found out to be 10.4mM for 20 minutes. This time-NaOCl concentration interaction was found out to significantly produce a higher number of clean surviving explants than all other interactions (P=<0.0001). The best callus formation frequency of 68% was observed in MS media supplemented with 2.0mg/lBAP+0.8mg/lKin+0.4mg/l NAA+0.5mg/lTDZ, compared to a 39% callus formation frequency observed in media supplemented with 1.5mg/lBAP+0.8mg/lKin+0.4mg/lNAA+0.5mg/lTDZ and a 13% callus formation frequency observed in media supplemented with 1mg/lBAP+0.4mg/lKin+0.2mg/lNAA+0.05mg/lTDZ. Although somatic embryos formed in all media types, only media supplemented with 2.0mg/lBAP+0.8mg/lKin+0.4mg/lNAA+0.5mg/lTDZ formed most somatic embryos which survived to maturity and formed shoots, as most calli and embryos forming in other PGR supplementations died with subsequent subcultures. Roots only formed in shoots cultured in media supplemented with 1.0 BAP+0.5 IBA. The successful development of this regeneration protocol is expected to greatly contribute to mass production and conservation of this important shrub.
Vibrational feedback control of time delay systems

This paper applies vibrational feedback control to time-lag systems. Both stabilization and transient issues are discussed. An illustrative example is given which demonstrates that the proposed controller: 1) provides superior system gain and phase margin in comparison to time invariant controllers when applied correctly; 2) is not robust with respect to unknown delays; and 3) does not have zero placement capabilities, in the sense defined in the paper.
Alternative Sigma Factor HrpL of Pectobacterium carotovorum 35 is Important for the Development of Soft-rot Symptoms

A bacterial artificial chromosome library of Pectobacterium carotovorum 35 was constructed to characterize the genome and to sequence its hrp region. The hrp cluster of P. carotovorum 35 consisted of 26 open reading frames in five operons. A promoter-based green fluorescent protein technology was used to identify the genes regulated by the alternative sigma factor, HrpL, in P. carotovorum 35. The majority of the selected clones contained the hrpJ operon promoter sequence, which harbors a hrp box, but no putative hrp boxes were detected within the promoter sequences of two other hrpL-regulated genes encoding for pectate lyase and large repetitive protein. Although the promoters of five other hrp operons also contained hrp boxes, their expression was not HrpL-dependent in the promoter-based selection in E. coli. However, transcriptional analysis showed that expression from all operons harboring hrp boxes, except for the hrpN operon, was reduced significantly in the hrpL mutant. The severity of soft-rot symptoms when the hrpL mutant was applied to the surface of tobacco leaves, mimicking natural infection, was greatly attenuated. These results indicate that the hrpL gene of P. carotovorum 35 may be involved in the development of soft-rot symptoms.
Corporate Governance and Firm Performance: Results from Greek Firms

In this paper, we construct a Governance Index for a sample of Greek companies quoted on the Athens Stock Exchange. We then classify firms, using each firm governance index, into three governance portfolios. Furthermore, the Fama and French model, extended to include a momentum variable, is tested for each of the three governance portfolios. Our findings suggest that most of the firms in our sample are semi-democracies followed by democracies and dictatorships respectively. Good governance appears to be of value in as much as we found higher Tobin’s q ratios for democracies followed by semi-democracies and dictatorships. We, also, report significant negative abnormal returns for shareholder-friendly and manager-friendly firms. The findings of significant negative abnormal returns are consistent with inefficient capital markets. At a practitioner level, the results imply that firms should practice vigorously good governance, as it is a policy of value to shareholders and possibly to other stakeholders.
