Hållbarhetens påverkan vid beslutsfattande : En kvalitativ flerfallstudie om SMEs med en hållbarhetsprofil

Alm, Emil, Andersson, Fanny January 2022 (has links)
Corporate social responsibility (CSR) and sustainability are concepts that have become increasingly more relevant, where it is no longer accepted by society that companies only prioritize the interests of shareholders without also looking to the interests of society. This has led to large companies being obligated to make sustainability reports in order to report their impact on society. This does not apply to small and medium-sized enterprises (SME) and therefore we have chosen to investigate how SMEs that have a clear sustainability profile are affected by sustainability in their decision-making. There has been some research on why one chooses to be more sustainable as an SME, but there has been little research on how this affects the SMEs who work with sustainability in their day-to-day business decisions when they have more than the shareholders to answer to. To investigate this phenomenon, we have done five case studies where we have interviewed five people who are involved in the decision-making in different SMEs. The purpose is to understand how small and medium-sized enterprises that have a clear sustainability profile work with sustainability and how that in turn affects their decision-making. To descriptively describe how decisions are made in relation to sustainability we have used several theories to capture the overall multifaceted reality that these SMEs are faced with in their decision-making. This in turn has made it possible for us to describe this reality by understanding to what extent the companies work with sustainability, how that in turn affects the reference points the companies have and how the interpretation of risk becomes a determining factor in how a SME makes its decisions.  What we have seen is that decisions are governed by aspects such as the extent to which sustainability permeates the company which in turn affects the reference point that is chosen when weighing the utility of different decisions. We have also seen how companies interpret risk affects to what extent they choose to compromise in their sustainability work. Industry aspects have also been an affecting factor as some companies are more dependent on other stakeholders for their operations which creates a complicated balance between how you weigh the financial against the sustainable. / Corporate social responsibility (CSR) och hållbarhet är något som har blivit alltmer relevant, där det inte längre accepteras av samhället att företag bara prioriterar aktieägarnas intressen utan att man också ser till samhällets intressen. Detta har lett till att stora företag har blivit tvungna att göra hållbarhetsrapporteringar för att redovisa deras påverkan på samhället. Detta gäller inte små och medelstora företag (SME) och därför har vi valt att undersöka hur SME som har en tydlig hållbarhetsprofil påverkas i sitt beslutsfattande när det kommer till hållbarhet. Det har forskats en del om varför man väljer att vara mer hållbar som SME men det har forskats lite kring hur detta påverkar SMEs med en hållbarhetsprofil i sina dagliga beslut när man har fler intressenter att svar till. För att undersöka detta fenomen har vi gjort fem fallstudier där vi har intervjuat fem personer i en beslutsfattande position i olika SMEs. Syftet är att förstå hur små och medelstora företag som har en tydlig hållbarhetsprofil arbetar med hållbarhet och hur det påverkar deras affärsbeslut. För att deskriptivt beskriva hur beslut tas gentemot hållbarhet har vi nyttjat flera teorier för att på en övergripande nivå fånga den multifacetterade verklighet som dessa SME ställs inför i sina beslut. Detta har gjort att vi har kunnat beskriva denna verklighet genom att förstå i vilken utsträckning man arbetar med hållbarhet, hur det i sin tur påverkar de utgångspunkter man har och hur tolkningen av risk blir avgörande för hur dess SME tar sina beslut. Det vi har sett är att beslut styrs av aspekter som i vilken utsträckning hållbarhet genomsyrar företaget vilket i sin tur påverkar mot vilken referenspunkt företaget värderar sina beslut. Detta påverkar i sin tur hur man upplever nyttan av olika beslut. Vi har också sett att hur man tolkar risk leder till i vilken utsträckning man är villig att kompromissa i sitt hållbarhetsarbete. Branschaspekter har också haft en påverkan då vissa företag är mer beroende av andra intressenter för sin verksamhet vilket skapar en mer komplicerad balansgång mellan hur man väger det finansiella mot det hållbara.

Problems and prospects of teaching chemical equilibrium at the further education and training (FET) band

Marumure, Godfrey Pisirai 11 1900 (has links)
Several misconceptions show up when learners answer questions on Chemical Equilibrium during examinations. Literature from other researchers shows similar trend of misconceptions (Johnstone, 2000; Morais, Paiva and Barros, 2007; Adesoji and Babatunde, 2008) for example, ‘apply pressure to the reactants’ (Johnstone, 2000). This shows that Chemistry has no meaning to these learners and they end up with misconceptions as they try to memorise facts in order to pass examinations. Learners are taught before writing these examinations, but how are they taught the concepts of Chemical Equilibrium? A descriptive approach was used on an exploratory survey conducted in Thohoyandou Cluster among Physical Science (Chemistry) FET band Educators. Cluster sampling of 40 educators from 18 randomly sampled schools responded to questionnaires. Five ‘well experienced’ educators who have been producing ‘good’ results at Grade 12 NSC examinations and two Physical Sciences subject advisors were interviewed. Using Spearman Brown Split-Half statistical method a 0,891 reliability coefficient was obtained. Research results show lack or under utilisation of laboratory equipment, teaching strategies which promote rote learning. Lack of confidence of educators due to deficiency in topic content knowledge and pedagogical skills which promote conceptual understanding were identified. Problem of English language leading to communication breakdown between educator-learners and between learner-subject leading to emergency of knowledge gaps in learners. Educators consider professional development through re-training and workshops on subject content matter and teaching strategies as the way forward to improve the quality of teaching. Topic specific PCK focusing on problem-solving strategy was recommended as a means to increasing educators’ efficiency in teaching and enhance learners’ comprehension and achievement in Physical Science. / Science and Technology Education / M.

A Structural Analysis of the Simpson Mountains

Briscoe, Hyrum A. 07 June 2023 (has links) (PDF)
The Simpson Mountains have long been of economic interest and have renewed interest in their potential value. Field mapping of the project area redefined structural relationships between stratigraphic units. Geometric and kinematic analysis of structures in the Simpson Mountains show the range is deformed by the three most recent tectonic events: the Sevier Orogeny, the Laramide Orogeny, and Basin and Range Extension. Laramide structures define the range with a significant E-W normal fault and an E-W thrust fault, which are both likely related to Eocene-age igneous intrusions. Principal component analysis (PCA) of regional quartzite X-ray Fluorescence (XRF) data resulted in distinctive populations between the Eureka Quartzite and the Mutual and Prospect Mountain Quartzites. The PCA was paired with petrographic analysis of regional quartzites where samples were diagnostically classified to help validate the PCA results. XRF analysis of volcanic rocks show volcanic arc origin. 40Ar/39Ar dating of the volcanic rocks associated with the intrusions yield new ages of 34.09±0.10 to 37.05±0.06 Ma and 19.11±0.02 to 19.18±0.03. Lithostratigraphy of the map area was validated by identification of fossil samples. The Eocene intrusions are likely sources of mineralization in the range along older Sevier structures.

Unga investerare : Risktagande på börsen / Young investors : Risk taking on the stock market

Ström, Anton, Svensson, Linda January 2023 (has links)
En granskning har avslöjat att många svenska ungdomar lockas med att köpa dyra utbildningar för att lära sig handel med riskfyllda finansiella instrument. Med argument att slippa traditionella heltidsarbeten samt drömmen om ekonomisk frihet väljer allt fler ungdomar att tillträda börsen och handla med finansiella instrument. Antalet svenska aktieinvesterare har de senaste fem åren ökat från 2,1 till 2,7 miljoner där största faktorn är att unga hittat till börsen. Hoppet om god avkastning är anledningen till att personer väljer att placera tillgångar i värdepapper i stället för att spara på sparkontot. Sammantaget i takt med att investeringsalternativen blivit allt fler bör det finnas en ökad ofrivillig riskbenägenhet hos unga investerare. Då risktagande är en av de mest centrala delarna vid investering av finansiella instrument kan en monetär förlust avskräcka en ung investerare från börsen om inte risk tas med i beaktningen. Syftet med studien är därmed att undersöka unga människors attityd till risktagande gällande investeringar på börsen. Vidare undersöks unga investerares syn på risk för att bilda en förståelse kring varför allt fler unga agerar som de gör på börsen. Denna studies syfte besvaras med hjälp av en kvantitativ forskningsmetod och med utgångspunkt i portföljteorin, prospektteorin, beslutsteorin och det kulturella riskperspektivet. Studien har gjorts i syfte att bidra med kunskap och förståelse kring unga människors investeringsstrategi för att kunna öka riskmedvetenheten bland unga investerare. Datamaterialet har inhämtats via en enkätundersökning som belyser hur de 611 respondenter ser på risk. Studiens resultat påvisar att det finns högmod bland unga investerare vilket betyder att de underskattar sitt risktagande eller rentav inte förstår vilken risk de utsätter sig för. Studien bekräftar att lockelsen av att tjäna snabba pengar genom handel med riskfyllda finansiella instrument kan komma att ta över den unga investerares rationella och välgrundade investeringsbeslut. / An investigation has revealed that many Swedish young people are lured into buying expensive training courses to learn how to trade risky financial instruments. With the argument of avoiding traditional full-time jobs and the dream of financial freedom, more young people choose to join the stock exchange and trade in financial instruments. In the last five years, the number of Swedish investors has increased from 2.1 to 2.7 million, where the biggest factor is that young people have found the stock market. The hope of a good return is the reason why people choose to invest assets in financial instruments instead of holding it at a savings account. Overall, as the investment alternatives have become more abundant, there should be an increased involuntary risk propensity among young investors. As risk taking is one of the most central parts of investing in financial instruments, a monetary loss can discourage a young investor from the stock market if risk is not taken into consideration. The purpose of the study is thus to examine young people's attitude to risk-taking regarding investments on the stock market. Furthermore, young investors' view of risk is examined to form an understanding of why more and more young people act as they do on the stock market. The purpose of this study is answered using a quantitative research method and based on portfolio theory, prospect theory, decision theory and the cultural risk perspective. The study has been done with the aim of contributing knowledge and understanding about young people's investment strategy in order to increase risk awareness among young investors. The data has been collected through a survey that highlights how the 611 respondents view risk. The results of the study show that there is arrogance among young investors, which means that they underestimate their risk-taking or even do not understand the risk they are exposing themselves to. The study confirms that the lure of making quick money by trading in risky financial instruments can overtake the young investor's rational and informed investment decisions.

Effects of Behavioral Decision-Making in Game-theoretic Frameworks for Security Resource Allocation in Networked Systems

Mustafa Abdallah (13150149) 26 July 2022 (has links)
<p>Facing increasingly sophisticated attacks from external adversaries, interdependent systems owners have to judiciously allocate their (often limited) security budget in order to reduce their cyber risks. However, when modeling human decision-making, behavioral economics has shown that humans consistently deviate from classical models of decision-making. Most notably, prospect theory, for which Kahneman won the 2002 Nobel memorial prize in economics, argues that humans perceive gains, losses and probabilities in a skewed manner. While there is a rich literature on prospect theory in economics and psychology, most of the existing work studying the security of interdependent systems does not take into account the aforementioned biases.</p> <p><br></p> <p>In this thesis, we propose novel mathematical behavioral security game models for the study of human decision-making in interdependent systems modeled by directed attack graphs. We show that behavioral biases lead to suboptimal resource allocation patterns. We also analyze the outcomes of protecting multiple isolated assets with heterogeneous valuations via decision- and game-theoretic frameworks, including simultaneous and sequential games. We show that behavioral defenders over-invest in higher-valued assets compared to rational defenders. We then propose different learning-based techniques and adapt two different tax-based mechanisms for guiding behavioral decision-makers towards optimal security investment decisions. In particular, we show the outcomes of such learning and mechanisms on four realistic interdependent systems. In total, our research establishes rigorous frameworks to analyze the security of both large-scale interdependent systems and heterogeneous isolated assets managed by human decision makers, and provides new and important insights into security vulnerabilities that arise in such settings.  </p>

Právní úprava rybářství / The Legal Regulation of Fishery

Lubovský, Zbyněk January 2014 (has links)
IN THE ENGLISH LANGUAGE The subject of my doctoral dissertation is an exploration of fishing rights as a collection of a wide range of legal norms regulating the behavior of the recipients only in the performance of fishing, but also in civil, administrative and criminal relations with the breeding and hunting fish related. Due to the current lack of scientific literature on this topic, the thesis also basic definition and status of the Czech Fishing rights in the legal system of the Czech Republic and important connections not only in relation to the institutions of environmental law, but also of civil and criminal law. Basic Institutes of fishing rights are always described as in historical context, as from the time of its inception developed, as well as in international comparisons of countries that their cultures are very close to us.

台灣證券交易所投資人交易行為與股票報酬關係之研究 / Investor Trading Behavior and Stock Returns in Taiwan Stock Exchange

夏清田, Hsia, Ching-Tian Unknown Date (has links)
This paper investigates the investor trading behavior and the relationship between investor sentiment and stock returns. First we explore whether individual investors behave as the Disposition Effect stated — hold their losers too long while realize their winners too soon. Second, we apply four sentiment indicators — number of recommended stocks, margin purchase value, net fund redemption and odd-lot trade value — to examine relationship between investor sentiment and stock returns. We would like to see if past returns have anything to do with current sentiment, and if sentiment provides predictive power to future returns. First of all, from our analysis to over eight hundreds cash accounts trading records in two research periods, January to March and September to December in 2000, we found the Disposition Effect holds in average but not statistically. Second, the number of recommended stocks, weighted number of recommended stocks, margin purchase value, change in margin purchase value, net fund redemption and odd-lot trade value as proxies of investor sentiment are good at measuring the effect of past 4-week and 26-week returns on sentiment. Third, the margin purchase value, net fund redemption and odd-lot trade value provide predictive power to future 26-week returns in our study, which also implies there is likely underlying mean-reversion within half year during the research period.  Finally, exploiting the change in margin purchase value as proxy of investor sentiment, we found the past 4-week returns volatility is inversely related with the indicator. That is, investors are scared on facing with high returns volatility.
