Kajian Teologis 1 Petrus 5:7 tentang Perlindungan Allah terhadap Orang Percaya di Tengah Pandemi Covid-19
Authors: Santo Joseph Christ , Arifianto Yonatan Alex
Published: August 2021

The Covid-19 pandemic has had a very heavy impact on humans to survive. The problem that is felt by all elements of society is related to the economy and the fulfilment of the necessities of life, but also the fear of being exposed to this virus haunts believers. Therefore, governments in affected countries must enact regulations that make the economy's wheels stagnate, as a result, economic problems are a serious problem in the fight against the Coronavirus. This research aims to answer how the concept of protection guarantees for believers is applied in the study of God's word, as a basis and insight to be able to survive and continue the opportunity to live in God's prerogative amidst the threat of the Covid 19 pandemic and the continuing impact that follows. With the formulation of the problem, the literature research method is used with a descriptive qualitative approach. It can be concluded that God's protection is a guarantee of God's providence that occurred in the Old and New Testament times which became the reference for the concept of God's care and protection during the pandemic period to bring believers to become obedient individuals to God by obeying the rules made by the government as a means of maintaining believers.AbstrakPandemi Covid-19 telah memberikan dampak yang sangat berat bagi manusia untuk bertahan hidup. Masalah yang dirasakan seluruh elemen masyarakat adalah berkenaan dengan ekonomi dan pemenuhan kebutuhan hidup, tetapi juga rasa kuatir akan terpapar virus ini menghantui orang percaya. Oleh sebab itu pemerintah di negara-negara terpapar harus memberlakukan peraturan yang membuat roda perekonomian tersendat, akibatnya masalah ekonomi menjadi problem yang serius dalam upaya melawan virus Corona. Peneli-tian ini bertujuan untuk menjawab bagaimana penerapankonsep jaminan perlin-dungan bagi orang percaya dalam kajian firman Tuhan, sebagai dasar dan wawasan untuk dapat bertahan dan melanjutkan kesempatan hidup dalam prerogatif Allah di tengah ancaman pandemi Covid 19 dan dampak berkelanjutan yang mengikutinya. Dengan rumusan masalah tersebut, maka digunakan metode penelitian pustaka dengan pendekatan kualitatif deskriptif. Disimpulkan bahwa God’s protection adalah jaminan pemeliharaan Tuhan yang terjadi dalam masa Perjanjian Lama dan Perjanjian Baru yang menjadi acuan konsep pemeliharaan dan proteksi Allah pada masa pandemi untuk membawa orang percaya menjadi pribadi yang taat kepada Tuhan dengan menaati aturan yang dibuat pemerintah sebagai sarana untuk meme-lihara orang percaya.

Published: August 2021

The Maitake (Grifola frondosa) is useful in treating diseases, specifically hypertension. Research on the maitake mycelia’s biological properties, nevertheless, are limited in the literature. This study aimed to (i) produce mushroom biomass adopting submerged fermentation, and (ii) investigate the Angiotensin-I Converting Enzyme inhibitory activity. Maitake mycelia’s yield after 14 days of fermentation under controlled conditions (approx. 1.32 g/L) were freeze-dried into powder and later were hydrolysed for analyses of Angiotensin-I Converting Enzyme inhibitory activity. Current results showed that the degree of hydrolysis increased in line with hydrolysis time, as the protein concentration for hydrolysed sample was 283.61 ± 7.14 µg/mL, however, the non-hydrolysed sample resulted in lesser protein content (46.76 ± 1.09 µg/mL). The hydrolysate maitake mycelia has higher Angiotensin-I Converting Enzyme inhibitory activity (46.48%) as compared to the non-hydrolysate maitake mycelia (20.19 ± 0.17%). This finding suggested maitake mycelia hydrolysate can be a source of potential bioactive peptides used in treating hypertension.

Published: August 2021

The textile industry is the largest industry contributing to the wastewater pollution and is a concern for the environment today. This pollution occurs when wastewater from the textile industry discharges the water into the river and it will affect both aquatic and human life. There are several ways to overcome this pollution problem but the current method is very expensive and its effectiveness depends on the colour of the dye. In this research, activated carbon of rice husk was used as an adsorbent to remove the methyl red dye from the wastewater. To detect the effectiveness of rice husk, two materials were used which were raw rice husk and also activated carbon to remove methyl red dyes from wastewater. There are four parameters used to investigate the optimum level which are the effect of initial dye concentrations ranges from (2 mg/L-10 mg/L), contact time (20-100 minutes), pH (2-10) and adsorbent dosage (0.5-2.5 g). The percentage of dye is calculated and recorded to see the comparison between raw rice husk and also activated carbon of rice husk. The results show that the rice husk can be used as a potential adsorbent to remove methyl red from the waste water.

Published: August 2021

Natural extract from plant-based has grown in popularity as protective properties in extender for preserving animal semen. Date palm pollen grain (DPPG) is commercially used for male fertility by enhancing sperm count, motility and DNA quality because DPPG contains flavonoids. Thus, the present study aimed to evaluate the effect of a) extender supplementation with different concentration of DPPG on sperm motility, viability and membrane integrity b) different preservation storage of chilled and frozen bovine semen after seven days. The semen was collected through electrical stimulation and assigned to four treatment groups. The semen were diluted in Tris citric fructose egg yolk (TCFY) diluent (control group; CG) or supplemented with DPPG with different concentration (G1 = 2%, G2 = 4% and G3 = 6% in 20 mg DPPG/40 mL of Tris citric fructose (TCF). Semen samples were chilled (experiment 1) in the refrigerator (4°C) for seven days and cryopreserved in liquid nitrogen (experiment 2) prior to dilution to four treatments. The samples were thawed in a water bath (37 °C) and analysed for motility, membrane integrity and viability by conventional laboratory methods. No significant difference was observed among treatment groups in experiment 1. However, in the second experiment, the addition of 6% DPPG resulted significantly higher (p<0.05) in sperm viability compared to control groups (71.25±1.04) vs (56.47±4.69). The supplementation of 6% DPPG showed the ability to protect the viability of bovine sperm, respectively.

Published: August 2021

The architectural style of buildings in Bali must be able to display the traditional Balinese architectural style (ATB) that is in harmony, balanced and integrated with the environment based on Balinese culture. Globalization and modernization encourage the creation of new technologies in the building materials industry to be more effective and efficient. Through a sociological juridical approach, it was found that the influence of globalization and modernization caused a shift in the architectural paradigm in Bali. Globalization and modernization have led to an identity crisis and the degradation of ATB towards a modern and minimalist direction as well as disharmony of traditional values ​​as the ancestral heritage of the people in Bali. The architectural paradigm shift in Bali has begun to shift and has deviated from the existing rules. The results of the study indicate that there has been a violation of the provisions on building architecture that have been stipulated through the Bali Provincial Regulation No. 5, 2005. Violations that take place seem to be left unchecked, ignorance or also a lack of public understanding of the norms that have been set. This is caused by the legal structure, legal substance and legal culture not working properly.

Recursos Estratégicos e Vantagens Competitivas na Gestão Pública Municipal: Um Estudo a partir da Percepção de Agentes Públicos com base na Resource Based-View
Authors: Soares Cristiano , Rosa Fabricia Silva da
Published: August 2021

Com objetivo de analisar os recursos estratégicos e as fontes geradoras de vantagens competitivas utilizadas na gestão pública municipal, com base na Resource-based View (RBV) foi realizada uma pesquisa qualitativa, exploratória e descritiva, por meio de estudo de caso no município de Santa Maria/RS. A coleta de dados ocorreu por meio de documentos, observações e entrevistas com agentes públicos. O uso da RBV no setor público pode auxiliar no desenvolvimento de indicadores de avaliação do desempenho da organização. Os resultados ressaltam a necessidade e escassez dos recursos financeiros e o reconhecimento dos recursos humanos e organizacionais como estratégicos, emergindo o recurso político como contribuição à teoria. O estudo conclui que os critérios componentes do modelo VRIO (valor, raridade, inimitabilidade e organização) carecem de adaptações, tendo em vista que a geração da vantagem competitiva se dá em relação aos entes da mesma esfera governamental.
Understanding Korean Immigrants and Major League Baseball Fandom
Authors: Kim Jiho , Shin Stepehn Hankil
Published: August 2021

Currently, there are more than 40 million immigrants in the United States, and immigrant sports consumers have been considered a significant niche market in the sport industry. In particular, Major League Baseball (MLB) teams have realized that Korean immigrants, along with Japanese immigrants, are among the most attractive Asian immigrant MLB markets in the U.S., because of their large populations in the U.S. and the popularity of baseball in their native countries (Kim & Jeon, 2008). However, there has been limited research regarding Asian immigrants’ team identification with MLB teams.
The theoretical framework of this study is drawn from acculturation theory (Berry, 1997) and social identity theory (Tajfel, 1982). Berry defines acculturation as “the general processes and outcomes (both cultural and psychological) of intercultural contact” (Berry, p. 8). Acculturation theory has been widely used to explain the adaptation patterns of immigrants to a new society. This theory further explains not only how immigrants evolve in new cultural contexts resulting from migration, but also how they retain their original cultural contexts and beliefs while in their new society (Berry, 1997). According to Berry (1980), there are four types of acculturation strategies: integration, assimilation, separation, and marginalization. These four acculturation strategies differ according to immigrants’ efforts to adapt to new cultural contexts as well as the extent of their relationships with their new as well as with their old societies.
Social identity theory (Tajfel, 1982) is a useful theoretical framework for team identification. Social identity is defined as “the part of the individual’s self-concept which derives from their knowledge of their membership in a social group together with the value and emotional significance attached to that membership (p.2)”. Team identification research has been developed based on social identity theory and identity theory (Kwon, Trail, & James, 2007). Team identification is an extension of self-identity that results from a sports fan’s psychological connection to a team (Fink, Trail, & Anderson, 2002). The purpose of this study is to understand the Major League Baseball fandom of Korean immigrants by exploring factors associated with recent Korean immigrants’ team identification with MLB teams in the U.S.

Published: August 2021

Competitions in sport games can cause athletes to become overly immersed, and it can lead to violent incidents. In Korea, structural violence and animosity between senior and junior athletes and between coaches and athletes have been rampant in the field of sports (Sohn, 2011). Although criminal acts under the code of criminal procedure have been applied in many different cases of violence and the perpetrators have been punished, structural violence in sports community is still a chronic problem in Korea. The purpose of this study was to find and analyze specific examples of structural violence and actual cases of sports crimes occurring in sports to present countermeasures and mitigation measures against structural violence in the Korean sports community.

Irrigation management strategies for winter wheat using AquaCrop model
Authors: Ali M.H. , Abustan I.
Published: August 2021

Many regions of the world face the challenge to ensure high yield with limited water supply. This calls for utilization of available water in an efficient and sustainable manner. Quantitative models can assist in management decision and planning purposes. The FAO’s newly developed crop-water model, AquaCrop, which simulates yield in response to water, has been calibrated for winter wheat and subsequently used to simulate yield under different sowing dates, irrigation frequencies, and irrigation sequences using 10 years daily weather data. The simulation results suggest that “2 irrigation frequency” is the most water-efficient schedule for wheat under the prevailing climatic and soil conditions. The results also indicate decreasing yield trend under late sowing. The normal/recommended sequence of irrigation performed better than the seven-days shifting from the normal. The results will help to formulate irrigation management plan based on the resource availability (water, and land availability from previous crop).
Household Drought Risk Index (HDRI): Social-Ecological Assessment of Drought Risk in the Cuvelai-Basin
Authors: Luetkemeier Robert , Liehr Stefan
Published: August 2021

Droughts threaten many regions worldwide, in particular semi-arid environments of sub-Saharan Africa such as the Cuvelai-Basin in Angola and Namibia, as the population depends on critical water-related ecosystem services. Since droughts are multi-layered phenomena, risk assessment tools that capture the societal relations to nature and identify those individuals that are most threatened are required. This study presents the integrated Household Drought Risk Index (HDRI) that builds upon empirical data from the study area to provide insights into drought hazard and vulnerability conditions of households in different socio-economic and environmental settings. The composite indicator integrates environmental measures of drought (frequency, severity, duration) from multiple remote sensing products (precipitation, soil moisture, vegetation) and the vulnerability of households (sensitivity, coping capacity) obtained from a structured survey that comprised 461 households. The results reveal that the Angolan population shows higher levels of risk, particularly caused by less developed infrastructural systems, weaker institutional capabilities and less coping capacities. Overall, urban dwellers follow less drought-sensitive livelihood strategies, but are still connected to drought conditions in rural areas due to family relations with obligations and benefits. The study results provide knowledge for decision-makers to respond to drought in the short and long-term. The latter may build upon the extension of centralized and decentralized water and food supply/production systems as well as the support of households via targeted educational and community-building measures. Specific HDRI components may be included in census surveys to receive continuous drought risk data.
Indoor Fine Particle (PM2.5) Pollution and Occupant Perception of the Indoor Environment During Summer of the First Passivhaus Certified Dwelling in Latin America
Authors: Moreno-Rangel Alejandro , Sharpe Tim , Musau Filbert , McGill Gráinne
Published: August 2021

This study compares the only residential Passivhaus in Mexico (located in Mexico City) to a conventional building-practice home in terms of indoor environmental quality during summer, specifically indoor air quality (IAQ) and the occupants’ perceptions towards it. Temperature, relative humidity, carbon dioxide, and PM2.5 were monitored during May, June and July 2016 in the living room, bedroom and kitchen of each home. Simultaneous outdoor air measurements were collected from the local pollution monitoring network. Online surveys were used to obtain data on building-related illnesses; while occupant perception of IAQ and thermal comfort and occupant diaries helped to provide insights into occupant behavior. Results from this case study suggest that Passivhaus design strategies could help to protect building occupants from outdoor air pollution, based on the lower concentrations of PM2.5 that were found in the Passivhaus apartment compared to the external environment. This contrasted with the results of the control home where PM2.5 levels were higher than ambient levels. Whilst the results cannot be generalized, they do provide much needed evidence on the indoor environmental performance of a Passivhaus-certified dwelling in Latin America, highlighting areas for improvement and providing recommendations to help inform future developments adopting these principles in a subtropical highland climate.

Burnout among the working population. Results of the Maastricht Cohort Study

IJ. Kant, N.W.H. Jansen, L.G.P.M. van Amelsvoort, D.C.L. Mohren & G.M.H. Swaen, Gedrag & Organisatie, volume 17, February 2004, nr. 1, pp. 5-17.

The aim of this study was to describe the prevalence of burnout among the Dutch working population in a large study sample. Data of the Maastricht Cohort Study on Fatigue at Work (N=12,140) were analyzed. This study shows that burnout has a one-year incidence of 6.1% and is highly prevalent (16.4%) among the working population, and is strongly associated with both objective situational job and family characteristics and health status. However, burnout appeared to be associated with organizational aspects as well. Our approach of comparing prevalences between different groups, based on a large study sample, is suitable for detecting and describing possible risk groups for burnout. Furthermore, this study shows large differences in the prevalence of burnout, both between companies within one occupational sector and between departments within one company. It is concluded that the detection of burnout risk groups should be based on (objective) job and family characteristics and health, rather than solely on occupation.

To stress or relax: neurochemical aspects of activity and rest

M. Tops, M.M. Lorist, A.A. Wijers & T.F. Meijman, Gedrag & Organisatie, volume 17, February 2004, nr. 1, pp. 32-42.

In this paper we formulate ideas about acute and chronic fatigue (especially burnout) in terms of brain neuromodulator functions. We describe dopaminergic, serotonergic and norepinephrinergic functions in energy expenditure and their role in the initiation and maintenance of behavior. We specifically focus on a dopaminergic approach-system, since there is accumulating evidence that dopaminergic systems play a central role in the symptomotology of fatigue. We argue that many symptoms of both acute fatigue and burnout can be seen as reflecting a decreased approach-motivation. Within the neuromodulator framework we propose two possible mechanisms for the development of burnout. We hope that our attempt to offer a physiological substrate for psychological ideas concerning fatigue and burnout will lead to new insights at a more applied level.

Social perception as entrance for systemwide organizational change: Change through a social constructionist' strategy

A.T.M. van Nistelrooij, Gedrag & Organisatie, volume 17, august 2004, nr. 4, p. 242-521

By developing a strategy that links up with normative-re-educative assumptions of the Organization Development approach this article tries to extend the understanding of producing intentional change from a social-constructionist' perspective. This strategy is based on unfolding a dialogue with the whole system. A social-constructionist' approach respects the unique reality of each stakeholder, pays attention to the context, emphasises the symmetric and mutual nature of dialogue in which meanings are (re-)produced. The article points out that one of the most basic mechanism of realizing change is to discover in a conversational process that the interpretation that someone else puts on a concept is different from one's own. Regarding the planned change nature of OD there are some implications for the way a dialogue should be organized, the role of management and the selection of a suiting intervention method.

Mental fatigue and goal-oriented behaviour: effects of task context on behaviour guidance

Dimitri van der Linden, Gedrag & Organisatie, Volume 17, August 2004, nr. 4, pp. 252-271.

As mental fatigue is related to performance and safety, it has received considerable interest from researchers in work psychology. Nevertheless, much is unknown about the specific way fatigue affects task behaviour and performance. In the current article we argue that fatigue affects behaviour through a decreased impact of conscious goals and behavioural rules on choice of actions. This would manifest itself as a diminished cognitive flexibility and as difficulties in executing or initiating planning. We present two experiments in which we investigate whether fatigue-induced participants show less flexibility and planning than non-fatigued participants. In experiment 1 (n = 65), participants had to explore a computer application unfamiliar to them. In experiment 2 (n = 58) participants worked on standard neuropsychological tests that assessed flexibility and planning. The results of both experiments showed that, compared to the non-fatigued participants, fatigue participants were less flexible and displayed less effective or less efficient planning. These results support the idea of decreased influence of conscious goals and rules under fatigue. This conclusion has practical implications for as it may support the prediction and prevention of fatigue-related errors and accidents.

The paradox of time and the future of W&O-psychology research

The paradox of time and the future of W&O-psychology research

Robert A. Roe, Gedrag & Organisatie, Volume 17, October 2004, nr. 5, pp. 342-350

Although the behavioral phenomena studied by W&O-psychology are essentially time-based, research almost completely ignores the time factor. This paradox is the focus of the present article. The consequences of neglecting the time aspect are discussed. Using a ficticious dataset that includes 2 variables, 10 respondents and 10 moments of measurement, and which is analyzed in six different ways, it is demonstrated that neglect of the time factor can lead to distorted results and wrong conclusions about the relationships between the variables. A plea is made for careful reporting on the ways in which the factor time is represented in studies. This is considered to be a first step towards an approach of theory and research that centers on temporal aspects of behavioral phenomena. It is expected that such an approach, which requires entirely new conceptualizations and alternative research methods, will lead to a W&O-psychology that offers a deeper understanding of human behavior in organizations than current insights.

The role of physical strain, psychosocial and psychological factors in relation to temporary and long-lasting lower back pain and sick leave in an occupational setting

The role of physical strain, psychosocial and psychological factors in relation to temporary and long-lasting lower back pain and sick leave in an occupational setting

Ellen Wijnen, Els Gheldof, J. Bart Staal & Jan Vinck, Gedrag & Organisatie, Volume 18, February 2005, nr. 1, pp. 32-46

This cross-sectional study examines a number of work related physical, psychosocial and psychological correlates of temporary and long-lasting lower back pain and sick leave among 712 employees of a Belgian metallurgical plant. Associations have been studied through multiple logistic regressions, while controlling for relevant confounders. The main conclusion is that physical strain is related to temporary lower back pain, and that physical strain and psychosocial factors such as job demands, power of decision and social support are associated with long-lasting lower back pain. A remarkable finding is that a lack of power of decision and a high level of fear of movement are significantly related to sick leave. Finally, the results show that the variables psychological job demands and power of decision clearly interact in their effect on sick leave.

Participative change management: a case study of the implementation of Customer Relationship Management

Participative change management: a case study of the implementation of Customer Relationship Management

Jelle T. Bouma & Ben J.M. Emans, Gedrag & Organisatie, Volume 18, April 2005, nr. 2, pp. 122-138

Participative change management is supposed to enhance employees' acceptance of intended changes and thus to contribute to their successful implementation. In a more refined view, it is hypothesized that additional mediating factors play a role in the relationship between participative leadership and successful organizational change. Among them are positive (success enhancing) factors, such as employees' understanding of the goal of intended changes and the fit of organizational change with local conditions on the one hand, and negative (success reducing) factors, such as stress and conflict, on the other. This view has been tested in a survey among 118 insurance employees, involved in a change process concerning the implementation of Customer Relationship Management (CRM). Results indicate an overall positive influence of participation. However, the hypothesized negative consequences did not occur. A possible explanation could be that the level of participation in the organization under study was rather low, that is, not surpassing the level of 'being informed', whereas negative participation effects may result only at high levels of participation ('being consulted' levels and higher).
Citation analysis in research evaluation

Het Institute for Scientific Information (ISI) introduceerde in 1964 de zogenaamde impact factor (IF), een grootheid die aangeeft hoe vaak het gemiddelde artikel in een bepaald wetenschappelijk tijdschrift gedurende een bepaalde periode na verschijning (gewoonlijk maximaal twee jaar) wordt aangehaald in andere wetenschappelijke publicaties. Dergelijke impactfactoren worden de laatste jaren steeds vaker gebruikt als instrument om inzicht te verkrijgen in de kwaliteit van wetenschappelijke tijdschriften, onderzoeksprogramma's, publicaties, individuele onderzoekers en onderzoeksgroepen. De achterliggende redenering is eenvoudig. Publicaties die vaak worden aangehaald zijn blijkbaar interessant voor een grote groep onderzoekers, wat suggereert dat die publicatie veel impact heeft op het onderzoek dat in een bepaald veld wordt verricht. Tijdschriften waarin veel van dergelijke veelaangehaalde artikelen verschijnen zijn dientengevolge van groot belang voor het veld; datzelfde geldt voor onderzoekers en onderzoeksgroepen die veel publicaties met een hoge impact realiseren. Kortom, impact is gelijk aan invloed is gelijk aan kwaliteit en prestige. Omdat de IF ook nog eens gemakkelijk en aan de hand van objectieve en duidelijke criteria te berekenen is, is deze grootheid een ideaal instrument om de kwaliteit van tijdschriften, onderzoekers en hun onderzoek in kaart te brengen en te beoordelen.

Stress or learning? Test of Karasek's growth and strain hypothesis among young workers in their first job

Stress or learning? Test of Karasek's growth and strain hypothesis among young workers in their first job

Hans De Witte, Elsy Verhofstadt & Eddy Omey, Gedrag & Organisatie, Volume 19, September 2006, nr. 3, pp. 232-250

Both hypotheses of Karasek's 'Job Demand Control' model are tested: high job demands (workload) and low job control (autonomy) are associated with strains (job dissatisfaction; strain hypothesis), whereas the combination of high job demands and high job control are associated with growth and development in the job (here: learning new skills in the first job; growth hypothesis). Both hypotheses are tested in two ways: (a) the mere combination of both job characteristics is associated with the expected outcomes, and (b) a statistical interaction between both job characteristics in predicting the outcomes is hypothesized. A large scale dataset of young workers in their first job is used to test all hypotheses. The results confirm both the strain and the growth hypothesis. We find evidence for a combined effect of both job characteristics, as well as for a statistical interaction between both variables. The lowest level of job satisfaction is found in the 'high strain' job, whereas the highest increase in skills is found in the 'active' job.

Emotions in work and organizations: An introduction to the theme

B.A. Nijstad, G.A. van Kleef & J. de Jonge, Gedrag & Organisatie, Volume 19, November 2006, nr. 4, pp. 313-322

The guest editors introduce the theme of this special issue on the role of emotions in work and organizations. The concepts of affect, emotion, and mood are defined, and the study of affect in organizations is put in a historic context. Examples of theoretical and empirical research in this field are given, in which the role of affect as a consequence, affect as a cause, and affect as a mediator is discussed. Finally, the five contributions to this special issue are briefly introduced. It is concluded that emotions in work and organizations is, and will be, an important issue for both society and science.
Emoties en distributieve rechtvaardigheid in organisaties: De rol van coördinatieregels

Emotions and distributive justice in organizations: The role of coordination rules

Emotions and distributive justice in organizations: The role of coordination rules

J. Stouten, Gedrag & Organisatie, Volume 19, November 2006, nr. 4, pp. 387-402

Distributive justice is an important factor in the emergence of emotional reactions in organizations. The present paper argues that two distributive coordination rules (the equality and proportionality rule) are especially related to people's emotions in situations in which there is a conflict between the individual and collective interests. If these coordination rules (or the conditions that give rise to these rules) are violated people react with negative emotions because important values are broken. In addition, it is shown that these emotional reactions induce retributive reactions, such as excluding or punishing the person who is responsible. A better understanding of these distributive coordination rules is needed in order to create a more complete picture of the influence of emotional reactions on behavior in organizations.
