Female Leadership Challenges : A Comparative Study Between Afghanistan and the Netherlands

Adesanya, Ruth, Tareen, Noorullah, Veldhuis, Bas January 2022 (has links)
Although the topic is trending globally, clear steps forward for female leadership are yet to be made. This is impacted even more by the fact that little empirical research has been conducted to examine the attitudes towards females in managerial positions from different countries' point of view. Therefore, the aim of this research is to get an understanding of the current state of affairs of female leadership in a more global context, with input from both developed and developing countries. Specifically, it explores the similarities and differences of female leadership challenges in Afghanistan and The Netherlands. To explore challenges experienced by, as well as strategies of, Afghan and Dutch female leaders, a qualitative study was conducted. Ten semi-structured interviews were done in-person and through video calls, consisting of 5 interviews for each country. Ten participants, meeting the criteria of holding a leadership/management position, were chosen through convenience sampling. The results showed significant similarities and differences in female leadership challenges, as well as strategies.  The unfortunate entanglement of culture in Afghanistan, under Taliban rule, has resulted in the oppression of female leaders. In the Netherlands, female leadership progress appears idealized. Nevertheless, female leaders in both countries share similar strength and strategies to cope with challenges themselves because society seemingly fails to bring change. As the results also show leadership skills specific to female leaders, societies and organizations worldwide should spread awareness and take action in gender equality, unlocking the full potential of female leadership.

Mångfald i arbetsmarknaden : Ett osynligt tak för människor med utländsk härkomst / Diversity in the labor market : An Invisible ceiling for immigrants

Samuel Asfaha, Johan Joel, Uludag, Can Ahmet January 2022 (has links)
Diskriminering är ett globalt fenomen som i dagens samhälle är oacceptabelt i många länder och kulturer. Det är något som drabbar många människor runt om i världen och många gånger är det av skäl man som person inte kan ändra på. Med den ökande globaliseringen och medvetenheten om vad som kan betraktas som acceptabelt och oacceptabelt har diskrimineringen hamnat högre upp på agendan. Detta har medfört att diskriminering inte bara prioriteras utav stater men också inom den privata sektorn. I denna kvalitativa studie undersöks hur diskriminering mot minoritetsgrupper påverkar de i arbetslivet. De delar som berörs under undersökningen är anställningsprocessen, arbetet och grupperingar i arbetet men även karriärmöjligheter. Undersökningsmetoden bestod utav kvalitativa intervjuer där respondenterna fick svara på frågor hur de uppfattade de olika sakerna baserat på deras arbetslivserfarenheter. Undersökningen omfattade sju personer där alla hade en kandidatexamen inom ekonomi, de olika respondenterna arbetade på olika arbetsplatser och olika arbetsuppgifter. Den teorier som använts är teorier som behandlar rekryteringsprocesser, diskriminering, stigmatisering och organisationsteori. Efter att ha analyserat det empiriska data och teorierna så visar forskningen på att det finns en viss del diskriminering på arbetsmarknaden. Dock är den väldigt beroende på faktorer som vart man arbetar och vilken typ av medarbetare man har på arbetsplatsen. / Discrimination is a global phenomenon today and is unacceptable in various countries and cultures. It is something that affect people around the world and often it’s for reasons that cannot change. With the increasing globalization and awareness of what can be acceptable and unacceptable discrimination has ended up higher in the agenda. This means that discrimination is not only prioritized by states but also in the private sector. This qualitative study examines how discrimination against minority groups affects them in working life. The parts that are affected during the survey are the hiring process, the work and groupings at work, but also career opportunities. The survey method consisted of qualitative interviews where the respondents had to answer questions about how they perceived the different things based on their work experiences. The theories used are theories that deal with recruitment processes, discrimination, stigma and organizational theory. After analyzing the empirical data and theories, the research shows that there is a certain amount of discrimination in the labor market. However, it is very dependent on factors such as where you work and what type of employee you have in the workplace.

Performance analysis and validation of high-temperature cooling panels in passive geothermal system

JImenez Lopez, Carlos January 2018 (has links)
High Temperature Cooling, HTC, is a thermal conditioning strategy, which aims to reducemixing and transfer heat losses. Cooling capacity strongly depends on heat transfer coefficientsand offers a great response and several advantages in terms of efficiency and sustainability.Among the advantages, there is evidence that HTC offers an increment of energy efficiency ofHVAC systems, provision of healthier and more comfortable indoor climate and provide widepotentials for the applications of renewable. This principle leads to a higher energy efficiency ofwater-based radiant cooling systems.This paper intends to focus on the research of the thermal capacity and performance of a newalternative. This is where Cooling Radiant Ceiling Panels, CRCP, becomes a major innovationwithin the sector and begin to take on certain relevance. The cooling capacity curve of thisparticular CRCP panels has been only measured in an idealized room environment according toDIN EN 14240. Thus, further studies of this key parameter through climate chamber testingand Computational Fluid Dynamics simulations, CFD, are necessary. CFD particularly focuseson fluids in motion, their behavior and their influences in complex processes such as heat transfer.The fluid motion can be described through fundamental mathematical equations and it isbecoming widely used within the building sector.Two different cases are going to be investigated. The first case will determine the mostoptimal peripheral gap to enhance cooling performance through Natural Convection, NC. Thisstudy states the existence of a peripheral gap around the panels has proven to be inefficientin terms of enhancing natural convection in the climate chamber. The second case is aboutcalculating the cooling capacity as a function of the internal heat loads. The cooling capacity ofthe CRCP panels followed an expected behavior. The R-squared factor of the linear regressionwas found to be 0.986, hence, it does not affect the performance of the CRCP panels dependingon the inclusion of the IHLs.This thesis provides the necessary information for the implementation of CRCP panels anddifferent possible operating environments, including considerations, limitations and recommendationsfor future implementation of this strategy.

Kvinnor på toppen - en karriär i motvind? : En kvalitativ studie om kvinnors utmaningar i toppositioner / Women on top - a career in headwind? : A qualitative research about women’s challenges in top positions

Falk, Thilda, Ekvall, Evelina January 2023 (has links)
Näringslivet kantas av en stundande underrepresentation av kvinnor på toppositioner. Därav är syftet med studien att skapa en förståelse kring vad det innebär och hur det upplevs för kvinnor att nå toppositioner i mansdominerade branscher. Vi kommer också att belysa vilka möjligheter och utmaningar kvinnorna fått möta under sin karriärväg till den toppositionen de idag besitter. Vår ambition är att undersöka den kvinnliga närvaron i toppskiktets upplevelser och erfarenheter av att vara minoritet i en svensk kontext. Studien bygger på en kvalitativ forskningsmetod med det empiriska insamlade materialet bestående av 8 stycken intervjuer med kvinnor i ledande befattning i högt uppsatt position verksamma inom olika, till synes mansdominerade branscher, runt om i Skåne, Blekinge och Västra Götaland. För att till fullo förstå den sociala företeelse som studeras, har vi konstruerat en teoretisk referensram som inkluderar relevanta teorier för studien. Vår studie resulterade i att kvinnor till största del anställs till en topposition utav män för att ersätta en annan man då organisationen befinner sig under mindre stabila förutsättningar. Resultaten visar på att de faktorer som gynnat kvinnorna i deras karriärväg är personliga egenskaper, kompetens och nätverk. Kvinnorna upplever utmaningar i de höga toppositionerna genom olika strukturella hinder till följd av deras könstillhörighet som kvinnor i många avseenden skapar själva. En reflektion från resultatet är därför att en jämställdhet i toppskiktet och en jämnare maktfördelning skulle leda till nyansering och ökad lönsamhet men framförallt leda till en jämnare könsfördelning fördelaktigt utifrån moral och social rättvisa. Sammanfattningsvis har vi kunnat fastställa att jämställdhetsprocessen förändras långsamt i toppskiktet, till följd av ökade institutionella krav från omvärlden. / *: Business life is edged by an imminent underrepresentation of women in top positions. Hence, the aim of the study is to create an understanding of what it means and how it has felt for women to reach top positions in male-dominated industries. We will also highlight the opportunities and challenges the women had to face during their career path to the top position they hold today. Our ambition is to investigate the female presence in the top layer's experiences and experiences of being a minority in a Swedish context. The study is based on a qualitative research method with the empirically collected material consisting of 8 interviews with women in senior positions in high-ranking positions active in various, seemingly male-dominated industries, around Skåne, Blekinge and Västra Götaland. To fully understand the social phenomenon that studies, we have constructed a theoretical frame of reference that includes relevant theories for study. Our study resulted in that women mostly being hired to a top position by men to replace a man when the organization is under less stable conditions. The results show that factors that have benefited women in their career path are personal characteristics, competence and networks. The women experience challenges in the high top positions through various structural obstacles as a result of their gender, which women in many respects create themselves. A reflection from the result is therefore that equality in the top layer and a more even distribution of power would lead to nuance and increased profitability, but above all lead to a more even gender distribution advantageously based on morality and social justice. In summary, we have been able to determine that the equality process is changing slowly in the top layer, as a result of increased institutional demands from the outside world. This thesis is written in Swedish.

Heating, ventilating and air-conditioning system energy demand coupling with building loads for office buildings

Korolija, Ivan January 2011 (has links)
The UK building stock accounts for about half of all energy consumed in the UK. A large portion of the energy is consumed by nondomestic buildings. Offices and retail are the most energy intensive typologies within the nondomestic building sector, typically accounting for over 50% of the nondomestic buildings’ total energy consumption. Heating, ventilating and air conditioning (HVAC) systems are the largest energy end use in the nondomestic sector, with energy consumption close to 50% of total energy consumption. Different HVAC systems have different energy requirements when responding to the same building heating and cooling demands. On the other hand, building heating and cooling demands depend on various parameters such as building fabrics, glazing ratio, building form, occupancy pattern, and many others. HVAC system energy requirements and building energy demands can be determined by mathematical modelling. A widely accepted approach among building professionals is to use building energy simulation tools such as EnergyPlus, IES, DOE2, etc. which can analyse in detail building energy consumption. However, preparing and running simulations in such tools is usually very complicated, time consuming and costly. Their complexity has been identified as the biggest obstacle. Adequate alternatives to complex building energy simulation tools are regression models which can provide results in an easier and faster way. This research deals with the development of regression models that enable the selection of HVAC systems for office buildings. In addition, the models are able to predict annual heating, cooling and auxiliary energy requirements of different HVAC systems as a function of office building heating and cooling demands. For the first part of the data set development used for the regression analysis, a data set of office building simulation archetypes was developed. The four most typical built forms (open plan sidelit, cellular sidelit, artificially lit open plan and composite sidelit cellular around artificially lit open plan built form) were coupled with five types of building fabric and three levels of glazing ratio. Furthermore, two measures of reducing solar heat gains were considered as well as implementation of daylight control. Also, building orientation was included in the analysis. In total 3840 different office buildings were then further coupled with five different HVAC systems: variable air volume system; constant air volume system; fan coil system with dedicated air; chilled ceiling system with embedded pipes, dedicated air and radiator heating; and chilled ceiling system with exposed aluminium panels, dedicated air and radiator heating. The total number of models simulated in EnergyPlus, in order to develop the input database for regression analysis, was 23,040. The results clearly indicate that it is possible to form a reliable judgement about each different HVAC system’s heating, cooling and auxiliary energy requirements based only on office building heating and cooling demands. High coefficients of determination of the proposed regression models show that HVAC system requirements can be predicted with high accuracy. The lowest coefficient of determination among cooling regression models was 0.94 in the case of the CAV system. HVAC system heating energy requirement regression models had a coefficient of determination above 0.96. The auxiliary energy requirement models had a coefficient of determination above 0.95, except in the case of chilled ceiling systems where the coefficient of determination was around 0.87. This research demonstrates that simplified regression models can be used to provide design decisions for the office building HVAC systems studied. Such models allow more rapid determination of HVAC systems energy requirements without the need for time-consuming (hence expensive) reconfigurations and runs of the simulation program.

Experimental investigation of heat exchange between thermal mass and room environments

Hudjetz, Stefan January 2012 (has links)
The different technologies of passive cooling concepts have to rely on a good thermal coupling between a building's thermal mass and indoor air. In many cases, the ceiling is the only surface remaining for a good coupling. Further research is necessary to investigate discrepancies between existing correlations. Therefore, the overall aim of the work described in this thesis is the investigation of heat transfer at a heated ceiling in an experimental chamber. Acoustic baffles obstruct the surface of the ceiling and impede heat transfer. However, there is nearly no published data about the effect of such baffles on heat transfer. Available results from simulations should be verified with an experimental investigation. Consequently, one of the primary aims of this work was to experimentally determine the influence of such acoustic baffles. A suitable experimental chamber has been built at Biberach University of Applied Sciences. The thesis describes the experimental chamber, the experimental programme as well as results from five different test series. With a value of ±0.1Wm⁻²K⁻¹ for larger temperature differences, uncertainty in resulting convective heat transfer coefficients for natural convection is comparable to that of results from an existing recent experimental work often recommended for use. Additionally, total heat transfer (by convection and radiation) results are presented. Results are given for natural, forced and mixed convection conditions at an unobstructed heated ceiling. Furthermore, results for acoustic baffles in both an unventilated and a ventilated chamber are shown. Natural convection results show a very good agreement with existing correlations. Under mixed convection conditions, convective heat transfer at an unobstructed ceiling decreases to the limiting case described by natural convection. Installation of acoustic baffles leads to a reduction in total heat transfer (convection and radiation) between 20% and 30% when compared to the case of an unobstructed ceiling.

兩性平權之研究─以女性警官陞遷為例

王芳美 Unknown Date (has links)
隨著婦女就業情形的普遍,兩性議題也愈顯得重要,欲落實兩性平權,法律是最根本之道,從近年政府制定「兩性工作平等法」及「性別平等教育法」對於推進兩性平權,均具有劃時代的意義。所謂「玻璃天花板效應」(glass ceiling effect),就是一種不易被察覺的、人為的或組織的偏差所造成的無形阻礙,使得女性在事業生涯方面,無法獲得與男性公平競爭的機會。本研究藉由對玻璃天花板、陞遷、性別角色等相關理論與實務之檢視,對我國女性警官陞遷潛藏之問題進行探討,期能依據研究結果,提出一些建議,以供女性警官個人及有關機關參考。 在研究方法方面,本研究係採用問卷調查法為主,以我國女性警官為普測對象,取得回收有效問卷525份。研究問卷內容包含影響陞遷之「社會心理」構面、「歧視偏差」構面、「系統結構」構面與「陞遷發展」構面及女性警官個人基本資料等量表。問卷調查所得資料運用電腦統計套裝軟體SPSS for Windows 10.0版,以描述性統計分析、t考驗、單因子變異數分析及Pearson積差相關等統計分析方法進行資料處理: 本研究經由實證分析之後,歸納結論如下: 一、就各構面之認知程度而言:其同意程度依次為影響陞遷之「社會心理」構面,其次是「陞遷發展」構面,再次是「歧視偏差」構面,最後為「系統結構」構面。 二、就各構面之認知差異情形而言:在「社會心理」構面上,因年齡、婚姻、子女數、教育程度、警官年資、職務官階、服務單位、有無進修、現任職位及代理主管的不同而有顯著差異存在;在「歧視偏差」構面上,因婚姻、職務官階、工作內容、現任職位及代理主管的不同而有顯著差異存在;在「系統結構」構面上,因工作照顧、教育程度、職務官階、有無進修及代理主管的不同而有顯著差異存在;在「陞遷發展」構面上,因有無進修、現任職位及代理主管的不同而有顯著差異存在。 三、就各構面之相關分析而言:本研究所探討的四個構面的關連非常強,不論是整體或是其各個的因素之間均達顯著水準的正相關。 / With the rise of female employment rate in workplace, gender issues have been of higher importance in recent years. To realize gender equality in workplace, legislation serves to be the most fundamental solutions of all. Following the enactment of the Gender Equality in Employment Law and the Gender Equality Education Law, Taiwan female employees have seen landmark on their workplace status. But the so-called glass-ceiling effects, are less perceivable, man-made or organizational bias still persist, which deprive female employees of an equal opportunity as those bestowed on their male counterparts. In this study, the author will discuss the obstacles posed for Taiwan’s female police officers in their quest organizational positions based on the observation from the theoretical and practical sides of glass-ceiling effects, promotional and gender roles, and will further propose suggestions for improvements for female police officers. Methodologically, this study uses questionnaire survey research, with female police officers as subjects and results in 525 successful samples. Contents of the questionnaire include facets of promotional importance, such as socio-psychology, discrimination bias, systematic structures, promotional development and personal information. With the analysis of descriptive statistics, t-test, one way ANOVA and the Pearson product-moment correlation coefficient supported by SPSS for Windows 10.0, information gathered from the results of questionnaire is processed: After empirical analysis, our conclusions are: 1.On the acknowledgement level of each facet: respondents find most of their agreements on the importance of obstacles to their promotion, are socio-psychology, promotional development, discrimination bias and systematic structure. 2.On the perceptional difference of each facet: on the socio-psychological aspect, there are differences according to the age, marital status, children number, educational level, years of working as police officer, rank, current position, deputy supervisor, further education. On the discrimination bias facet, there are differences according to marital status, rank, job description, current position and deputy supervisor. On the systematic structure facet, the differences exists among respondents of different educational level, rank, further education and deputy supervisor. On the promotional development facet, there are differences according to further education, current position and deputy supervisor. 3.On the correlation analysis of each facet: the four facets discussed in the study has strong correlations, no matter individual factor or integral whole has all reached a high standard level of positive relationship.

Snedrekrytering och mansdominans som organisationskulturellt fenomen

Sjögren, Fredrik, Sällvik, Fredrik January 2007 (has links)
<p>The purpose of this paper is to present a possible understanding of why the company Tekola is segregated according to sex. In accordance to this purpose, an understanding of how the segregation affects the employees in relation to power, values and possibilities is discussed. The theoretical understanding is that the organization of men and women within Tekola is done in close connection to creation of the meaning of gender in Tekola. This, in turn, affects and is affected by the recruitment to and within the company. Through the study of statistics from a survey, five interviews with employees and former employees and Tekolas’ equality plan, we are able to see the possible existence of a glass ceiling, and a culture of homosociality, which affects the possibilities of women to enter the company and also to gain full entrance to power-positions in a negative way. There is also a possibility that sexual harassment exists in Tekola. There is a clear feminization of one of the departments, a phenomenon that affects acts directed at and around that department. Also, we are able to see that there is a gap between the actual segregation between men and women in Tekola, and the employees’ perception of their possibilities.</p> / <p>Syftet med denna undersökning är att presentera en möjlig förståelse av varför företaget Tekola är könssegregerat. I linje med detta skapas även en förståelse av vad könssegregeringen betyder för medarbetarna i företaget i relation till makt, värderingar och möjligheter. Utgångspunkten för förståelsen av företagets organisering av kön är att könssegregeringen hänger samman med hur kön skapas i företaget, samt att detta påverkar och har samband med den interna och externa rekryteringen av män och kvinnor. Materialet som studeras består av statistik som skapats genom bearbetning av en enkätundersökning på företaget, fem djupintervjuer med anställda och före detta anställda samt Tekolas jämställdhetsplan. Analysen av materialet visar bland annat tendenser till förekomsten av ett glastak och en homosocial kultur vilket negativt påverkar kvinnors möjligheter att ta sig in på företaget samt att avancera. Det förekommer även troligtvis könsmässiga trakasserier. Samtidigt sker en tydlig märkning av en avdelning som kvinnlig, vilket påverkar olika handlingar riktade mot och kring denna avdelning. Det verkar även ha skapats en förståelse av att alla har samma möjligheter, något som motsägs av hur könsfördelningen faktiskt ser ut.</p>

星空下的玻璃天花板現象─以警政單位女性警官升遷為例 / Glass ceiling effect among female police officers

林祐慈 Unknown Date (has links)
台灣女性勞動參與率逐年提高,越來越多的女性勞動力進入就業市場,然而,女性晉升至中高階層職位之人數並無明顯增加。顯然女性的職涯發展似乎受到一定程度的限制,此限制即為玻璃天花板現象。玻璃天花板現象存在於各行各業中,但於警界之程度更為嚴重。此現象之原因乃警界人為與體制上的排除女警官人數,導致整個警界中的女性人數稀少,更遑論通往高階之女性所遇之玻璃天花板現象更甚一般企業或公務體系人員。因此本研究透過質性訪談方式,藉此試圖探討警政中、高層女性所占比例極低的原因何在,其中人為或非人為因素為何?   本研究發現警界升遷制度隱性侷限女警升遷發展,以績效導向為主導致功獎多寡牽制著積分排名順序,而主管評分比重過高亦會影響女警官升遷;再者由於警察組織性別化的工作指派,在偏好男性的外勤工作能夠快速與大量的累積分數之下,女警官敘獎機會較少,相對不容易累積積分;此外警界必須運用交際應酬的手段維繫良好的人際關係,但女警官不擅進入男性應酬圈,男性網絡之官場文化間接造影響女警官們的升遷發展;最後女性被賦予養兒育女之母職天性,家庭責任之重擔落在女性身上,一但女警官走入婚姻,即必須在工作與家庭上做取捨,工作與家庭實為難以兼顧。   因此建議國家應放寬警大入學名額的性別設限並推動國家照顧工作;對於警界之職務分派勿侷限性別,重視女警人才,並且減少組織內外勤工作差異,再者建議主官建立公平的考核原則,破除性別刻板印象之成見,以及建立兩性平等的教育訓練;建議女警官破除自我設限的迷思,並強化女警官之人際網絡;以及女警官人力資本之維持。 / The female labor participation rate has gradually increased in Taiwan, more and more Female labor force has been entered the labor market. However, the number of female senior positions who is not increases significantly. Women's career advancement has seemed to be limited to a certain extent; this restriction shall be the glass ceiling. The glass ceiling exists in all walks of life; particularly the police are more serious than the general business and public service system. The reason is artificial and institutional exclusion, not to mention the number of women with the senior positions. Therefore, this study through qualitative interviews so as to explore the low proportion of women in senior positions. The study found that promotion system limited women's career advancement, the performance-oriented approach the award amount in order to contain the standings, while the chief rates with a high proportion will also affect female police officer promotion; Furthermore, due to the gender-based assignment of work in police organizations, female police officers award fewer opportunities that is not easy to accumulate points; In addition to maintain good interpersonal relationships in police, female police officers is hard to enter the male entertainment circle; the last is that women has the nature of motherhood, so family responsibilities falls on women which must be choice between work and family. The government should be relax the gender-based retractions of Central Police University and to promote the care work of the state; the Police should not limit the duties assigned in gender and to value the talent of female police officers ,also it should reduce the differences in the police work of the organization .Moreover the chief should set the fair principal on assessment, and break the gender stereotypes with the prejudices. Also it should be establish the gender equality in education and training; finally suggesting that female police officers should get rid of the myth of self-handicapping, and to strengthen the interpersonal networks of female police officers; as well as the maintenance of female police officers in human capital.
