Leaders and subordinates perceptions concerning leader and climate dimensions in a Swedish company

This dissertation is part of an MSc program in International Project Management, at the University of Chalmers Lindholmen (Sweden) and Northumbria University (England). This dissertation studies the organisational climate and the existing leadership styles in a Swedish company. The aim was to investigate leaders and employees perceptions about the existing leadership styles and explore the organisational climate. It includes a study about leadership and climate dimension based on theory as well as empiric data. The theoretical part includes background to the subjects' leadership and organisational climate. Background to the subject was obtained by studying literature and research articles. The empirical part includes data gathered through a questionnaire. The ambition with the study was also to provide the management with information that could encourage development within the company. If management understands the needs of their employees, the quality on work could be improved. The results of the empirical study shows that there were no significant differences in perceptions regarding leadership style dimensions between neither leaders nor subordinates. However, regarding the climate dimension significant differences were found in perceptions between the two groups. Psychometrical analysis was made in order to distinguishing correlation between leadership style and work climate. Leaders result revealed that there were no significant correlations, though samples from subordinates showed significant correlations. The result was analysed and compared with reference data concerning both leadership styles and climate dimensions and several differences were found. The result indicated that both inquired dimensions; leadership and climate where scored significantly higher compared to reference data. The conclusions of the study are that result found in this research supports theories concerning both leadership styles and climate dimensions. The study reveals differences in between leaders and subordinates perceptions of the climate dimensions and in deeper analysis it was indicated that the result of the subordinates had a higher degree of correlation with references data. Leaders' awareness of differences in perception of their leadership style and what co-workers perceive are critical for leadership success. A large discrepancy reveals lack of self knowledge and poor leadership, which in turn could leads to a negative organisational climate. A company with a positive organisational climate gives a good hearsay and are most probably more competitive committing competent personnel and it most certainly gives higher quality on the work performed by the employees.
Doping and alloying of kesterites

Attempts to improve the efficiency of kesterite solar cells by changing the intrinsic stoichiometry have not helped to boost the device efficiency beyond the current record of 12.6%. In this light, the addition of extrinsic elements to the Cu2ZnSn(S,Se)4 matrix in various quantities has emerged as a popular topic aiming to ameliorate electronic properties of the solar cell absorbers. This article reviews extrinsic doping and alloying concepts for kesterite absorbers with the focus on those that do not alter the parent zinc-blende derived kesterite structure. The latest state-of-the-art of possible extrinsic elements is presented in the order of groups of the periodic table. The highest reported solar cell efficiencies for each extrinsic dopant are tabulated at the end. Several dopants like alkali elements and substitutional alloying with Ag, Cd or Ge have been shown to improve the device performance of kesterite solar cells as compared to the nominally undoped references, although it is often difficult to differentiate between pure electronic effects and other possible influences such as changes in the crystallization path, deviations in matrix composition and presence of alkali dopants coming from the substrates. The review is concluded with a suggestion to intensify efforts for identifying intrinsic defects that negatively affect electronic properties of the kesterite absorbers, and, if identified, to test extrinsic strategies that may compensate these defects. Characterization techniques must be developed and widely used to reliably access semiconductor absorber metrics such as the quasi-Fermi level splitting, defect concentration and their energetic position, and carrier lifetime in order to assist in search for effective doping/alloying strategies.
Paleomagnetism and Counterclockwise Tectonic Rotation of the Eocene-Oligocene Lyre, Quimper, and Marrowstone Formations, Northeast Olympic Peninsula, Washington State, USA

The Eocene-Oligocene Lyre, Quimper, and Marrowstone formations on the northeast Olympic Peninsula of Washington are an important sedimentary sequence whose age has long been controversial. They were thought to span the Eocene-Oligocene transition. In addition, previous paleomagnetic studies on the un- derlying volcanic rocks produced a counterclockwise tectonic rotation. We sampled three sections: West In- dian Island, West Marrowstone Island, and near Woodman's Wharf on Discovery Bay. After both AF and ther- mal demagnetization, all three formations produced a single-component remanence held largely in magnetite which passes a reversal test and is rotated counterclockwise by about 35°. This is consistent with the results from the underlying lower Eocene Port Townsend volcanics. It is also consistent with counterclockwise ro- tations obtained from the lower Eocene Metchosin volcanics and upper Oligocene Sooke Formation on the southern tip of Vancouver Island, showing that the counterclockwise rotation is widespread in the region. Based on magnetobiostratigraphic correlations with other sections in the region, we correlate the Lyre For- mation with late middle Eocene Chrons C15r-C16r (35.0-36.5 Ma). The Quimper Sandstone spans the Chron C15n and probably the lowermost part of Chron C13r (34.6-35.0 Ma), so the Eocene-Oligocene boundary probably lies in the middle of the Quimper Sandstone, as previously suspected. The Marrowstone Shale is correlated with late Chron C13r.
Local velocity measurements in the Shrek experiment at high reynolds number

We report preliminary results obtained using new local velocity probes in the Superfluid Helium high REynold number von Karman flow (SHREK) experiment for different forcing conditions. The presentation will focus on the validation of the signals obtained from a hot-wire and a total head pressure tube in both normal and superfluid phases of liquid helium.
Innovation Spaces: Towards a Framework for Understanding the Role of the Physical Environment in Innovation

Firms are paying increasing attention to the physical environments in which creative and innovative activities take place. These environments reflect the firm's strategic intentions towards innovation and provide a physical embodiment of their desired modes of working. To date, this new phenomenon has received little academic attention. Based on both literature and also the authors' combined experiences through observing firms in Europe, this paper proposes a simple framework to aid practitioners and academics to better understand the design, role and goals of such spaces.
Aboveground biomass in Prosopis pallida (Humb. and Bonpl. ex Willd.) H. B. K. ecosystems using Landsat 7 ETM+ images

La importancia del trabajo de campo en estudios de teledeteccion radica en la necesidad de proveer una validacion a los valores de reflectividad incluidos en los datos de los sensores remotos. La diversidad ecologica del medio forestal y la evaluacion de grandes superficies de dificil acceso hacen de la combinacion del inventario forestal y de la teledeteccion una herramienta compleja y util en el analisis del medio terrestre. El presente trabajo muestra la aplicacion de un inventario sistematico estratificado sobre un millon de hectareas de bosque tropical seco de Prosopis pallida en el Departamento de Piura (Peru) en la validacion de diferentes tipos de clasificacion realizadas sobre dicho ecosistema mediante el uso de imagenes Landsat ETM+. El inventario recoge las principales variables del ecosistema y de los individuos, tomadas en parcelas de 1 hectarea, que posteriormente fueron relacionadas con los valores de reflectividad de las imagenes mediante el uso de indices de vegetacion. Se hallaron ecuaciones de regresion entre valores de fraccion de suelo cubierto y cinco indices de vegetacion, obteniendose resultados con R2 de hasta 72 %. Los niveles de significacion hallados mediante el uso de los indices NDVI y EVI permiten una estimacion razonable del estado del bosque seco de Prosopis pallida del Departamento de Piura de una forma economica, facil de repetir en el tiempo y aplicable a zonas que dificilmente pueden ser evaluadas mediante inventarios convencionales
Implementation of findings of generation theories in engineering studies

M. McCrindledetermined generation borders and defined them sociologically.A lot of answers were found out about the peculiarities of nowadays students initiating changes in the study process at a higher school and education in general. The aim of the article is to assess the findings of generation theories and to analyze the opportunities of their implementation in higher education, and particularly in engineering studies. Cultural, historical, technological differences and their cross-influenceare analysed in the article in the context typical for each generation. Particular attention is paid to Generation Zbelonging students’ habits and values. It is stressed in the article that Generation’s Z challenges will be life in a dinamically changing world with various catastrophies, ecological and demographic crises, development of IT, including artificial intelligence as well as opportunities to choose the form of work (distance, at any time, regular). One of the main tasks of Generation Z will be to take complex decisions and solve problems for dynamically changing uncertain future. Therefore, a study at Jelgava Secondary School No. 5 had been carried out. The survey reflected answers of 55 respondents on motives of the choice of a profession and work values. 77 Latvia University of Life Sciences and Technologies (LLU) first year engineering students’ survey was done on their spending time in the Internet, relations with authoritarian teachers and expression of ideas freely.41educators of the LLUparticipated in the study analysing their strong and weak sides, opportunities and threats in relation to Generation Z. Studies had been done in the period from 2016 to 2018. Considering the theoretical and empirical results recommendations for the improvement of engineering studies were worked out.
THE MESOPROTEROZOIC VOLCANO-SEDIMENTARY SERRA DO ITABERABA GROUP OF THE CENTRAL RIBEIRA BELT, SÃO PAULO STATE, BRAZIL: IMPLICATIONS FOR THE AGE OF THE OVERLYING SÃO ROQUE GROUP

One of the fundamental problems to understanding the evolution of volcano-sedimentary sequences in southeastern Brazil is constraining their depositional ages. Brasiliano tectonic and metamorphic overprinting either obscured or destroyed primary features, such as unconformities, as well as other geologic relationships. This problem is exemplified by the Serra do Itaberaba and Sao Roque groups, where the lack of data about the timing of their deposition has prevented resolution of proposed one- and two-stage geotectonic/depositional models. Recent U-Pb zircon data obtained from metavolcanic rocks in the Sao Roque Group indicate that it was deposited between 628 and 607 Ma. New U-Pb zircon data of 1395 + 10 Ma for a metandesite in the basal Morro da Pedra Preta Formation (Serra do Itaberaba Group) indicate the maximum age for the beginning of the deposition of the pelites overlying MORB-like basalt. A metarhyolite of the upper unit, the Nhangucu Formation, contains two zircon populations. One yielded an age of 619 + 3 Ma, which defines the crystallization age of the rock, and the other an age of 1449 ± 3 Ma, interpreted as inherited xenocrystal grains from older units of the Serra do Itaberaba Group. The younger metarhyolite was affected only by the S, foliation, generated during the Brasiliano orogenesis, whereas the Middle Proterozoic metavolcano-sedimentary sequence records additional metamorphic and deformational events, confirming the presence of two different geotectonic cycles.

Antecedent Factors Impacting Country of Origin (COO): An Investigation into Food Provenance in China

This paper reports a study that sought to investigate the antecedent factors influencing consumer COO perceptions. A review of the literature revealed that most previous studies consider these factors independently, however, it is now widely accepted that consumer decision making does not involve the consideration of variables one-at-a-time but rather as a small group of factors often referred to as the evoked set. This study, therefore, set out to fill a gap in the knowledge regarding the factors influencing consumer COO when considered collectively. A model of the antecedent factors impacting COO was developed from the literature and a three stage methodology involving both qualitative and quantitative techniques was then used to test the model. The findings not only confirm COO as an important factor in the decision making process of Chinese consumers when purchasing food products but go on to suggest that the role played by the antecedent factors of COO is much more complex than the existing literature might suggest. The main limitations of the study related to the work being conducted in just one country (China) and the inherent issues associated with research that is based on sampling. Despite the limitations, the paper makes an original contribution to knowledge regarding antecedent factors impacting COO and presents a number of implications for both practicing marketing managers and academic theorists.
Making Sense of Out Phrasal Verbs: the Instruction of Out Senses

The issue of phrasal verb learning has caused much discussion and attracted vigorous investigation. Inspired by the theory of conceptual metaphor, a pedagogical experiment was conducted to investigate whether an approach focussing on sense extension of particle out in terms of conceptual metaphors can enhance the learning of phrasal verbs containing out. One control group was instructed with general reading materials embedded with various phrasal verbs, and two experimental groups with self-constructed lessons, in which six sense types of out were identified and corresponding phrasal verbs were selected, and in addition, an L1 lexical item was employed to illustrate the mechanism of metaphorical extension for one experimental group. The result showed that learners receiving a cognitive inspired approach to instruction achieved significantly better learning outcomes than those receiving the traditional approach, not only on taught items but also on untaught items. However, the use of L1 lexical items to illustrate sense extension was not as effective as expected in boosting the learning of out-phrasal verbs . It was concluded by discussing the benefit of the proposed approach to phrasal verb instruction and, more importantly, the need of teaching materials providing more profound understanding of phrasal verbs so as to facilitate phrasal verb learning.
Rock properties of Greywacke Basement hosting geothermal reservoirs, New Zealand: preliminary results

Geothermal resources in New Zealand are known to be hosted in greywacke basement rocks. Fluid flow in these reservoirs and the wells that access them is controlled by fracture networks. As such it is of vital importance to understand how these structures are impacted by the mechanical and thermal properties of this basement rock, and how these in turn are affected by changing temperature and pressure conditions at depth. This paper details the results of an initial set of laboratory tests of two New Zealand greywacke basement terranes, in which geothermal reservoirs are known to be hosted. The aim of the study was to provide an initial understanding of the rocks mechanical properties so that further, more refined testing could be applied. Low permeability and porosity measurements are consistent with the current understanding that fractures control fluid flow in the basement. Preliminary mechanical testing suggests a systematic difference between greywacke from the Waipapa and Torlesse Terranes, with the Waipapa Terrane being mechanically stronger, potentially as a result of a coarser grain size and/or composition differences. Tensile strength testing of whole rock and fractures in Waipapa greywacke rock show lower tensile strengths for the fractures. This indicates that geothermal fluid flow makes use of existing fracture networks via crack-seal mechanisms rather than through the generation of new fractures. Further work, including mechanical testing at; high temperature conditions, variable grain size, and variable composition will provide us with a better insight into the role increasing pressure and temperature conditions play in fracture controlled geothermal fluid flow as we approach the change from brittle to ductile deformation. This in combination with a rigorous investigation of the effects of the character and heterogeneity of greywacke basement in New Zealand will inform us on how best New Zealand can explore for and utilize deep (>3km), fracture dominated, geothermal resources.
Genetic and adaptive trait variation in seedlings of European beech provenances from Northern Germany

Abstract European beech (Fagus sylvatica L.) will most likely be threatened by climate change. Therefore, more knowledge of its adaptation potential to changing environmental conditions is required. Several studies showed differences in adaptive traits for beech populations from across Europe, but there is also growing evidence for microevolutionary processes occurring within short geographic distances in this species, or even a lack of local adaptation. Hence, a more regional perspective for adaptation research in beech might be appropriate. Here, we investigated the performance (height, height increment and mortality) and genetic structure based on microsatellite markers of 2400 beech seedlings from provenances growing along a temperature and precipitation gradient in Northern Germany in a common garden experiment. Differences for all traits were found among provenances. Provenances from lower precipitation areas did not perform better than provenances from higher precipitation areas at the common garden site, which was located near the lower precipitation limit of beech. Further, neighboring provenances growing on either sandy or loamy soils showed more different adaptive trait variation than distant provenances. We detected minor genetic structure among provenances and a high genetic diversity within them. Thus, small-scale adaptive trait variation in beech can occur, despite low but significant genetic population structure among provenances.
Oligocene fossils bearing on the origins of the Todidae and the Momotidae (Aves: Coraciiformes)

A new genus and species of tody, f okeofoduf ernyyt, is described from the "middle" Oligocene (Orellan land mammal stage) of Wyoming, providing the first record of the modem family Todidae outside the West Indies. The fossil bird frofomif gbrmffwis from the lower Oligocene of Switzerland is removed from the Alcedinidae to the Momotidae to provide the first occurrence of the latter family outside the New World. The Todidae and Momotidae appear to be more closely related to each other than either is to any other family of Coraciiformes. The Momotidae were evidently derived from the Old World. The Todidae appear to have been derived from a momotid-like ancestor in the Oligocene or earlier. The present distribution of these two families in the New World tropics is relictual. The Coraciiformes appear to have been one of the prevalent groups of small land birds in the Oligocene.
Extra Skeletal Ewing's Sarcoma: a Case Report

Ewing's sarcoma is an uncommon malignancy primarily affecting bone tissue and usually occurs in adolescents and young adults. This paper reports a rare case of extra-skeletal Ewing’s sarcoma of the oral cavity soft tissue. In the clinical examination, a mass of 1.5×1.5cm in diameter was observed in the right mandibular vestibule. Radiographic examination revealed no involvement of mandible. Microscopically, the tumor was composed of malignant small round cell tumor that exhibited immunoreactivity for CD99. Enucleation surgery under local anesthesia was performed for the patient and prognosis was excellent. The patient remained symptom-free after 13 months of follow-up.
GOCE-Derived Coseismic Gravity Gradient Changes Caused by the 2011 Tohoku-Oki Earthquake

In contrast to most of the coseismic gravity change studies, which are generally based on data from the Gravity field Recovery and Climate Experiment (GRACE) satellite mission, we use observations from the Gravity field and steady-state Ocean Circulation Explorer (GOCE) Satellite Gravity Gradient (SGG) mission to estimate the coseismic gravity and gravity gradient changes caused by the 2011 Tohoku-Oki Mw 9.0 earthquake. We first construct two global gravity field models up to degree and order 220, before and after the earthquake, based on the least-squares method, with a bandpass Auto Regression Moving Average (ARMA) filter applied to the SGG data along the orbit. In addition, to reduce the influences of colored noise in the SGG data and the polar gap problem on the recovered model, we propose a tailored spherical harmonic (TSH) approach, which only uses the spherical harmonic (SH) coefficients with the degree range 30–95 to compute the coseismic gravity changes in the spatial domain. Then, both the results from the GOCE observations and the GRACE temporal gravity field models (with the same TSH degrees and orders) are simultaneously compared with the forward-modeled signals that are estimated based on the fault slip model of the earthquake event. Although there are considerable misfits between GOCE-derived and modeled gravity gradient changes (ΔVxx, ΔVyy, ΔVzz, and ΔVxz), we find analogous spatial patterns and a significant change (greater than 3σ) in gravity gradients before and after the earthquake. Moreover, we estimate the radial gravity gradient changes from the GOCE-derived monthly time-variable gravity field models before and after the earthquake, whose amplitudes are at a level over three times that of their corresponding uncertainties, and are thus significant. Additionally, the results show that the recovered coseismic gravity signals in the west-to-east direction from GOCE are closer to the modeled signals than those from GRACE in the TSH degree range 30–95. This indicates that the GOCE-derived gravity models might be used as additional observations to infer/explain some time-variable geophysical signals of interest.
