Published: October 2022

Ikan nilem (Osteochilus hasselti) memiliki nilai ekonomis tinggi dan potensi besar untuk dikembangkan menjadi komoditas unggulan. Ikan nilem termasuk ikan yang memijah hanya pada saat musim penghujan yang mengakibatkan benih tidak tersedia secara kontinyu. Musim penghujan dan kemarau memiliki kondisi lingkungan yang berbeda. Hal ini mengakibatkan ikan-ikan yang memijah pada saat musim penghujan akan mengalami kondisi kurang optimal pada saat sedang berlangsungnya musim kemarau sehingga ikan tidak mampu memproduksi hormon reproduksi secara optimal. sGnRH-a dan anti dopamin dapat merangsang hormon gonadotropin meningkat sehingga pemijahan dapat dilakukan diluar musim pemijahan ikan nilem. Penelitian ini bertujuan mengetahui pengaruh sGnRH-a dan anti dopamin terhadap performa reproduksi ikan nilem dan mengetahui dosis terbaiknya. Penelitian dilaksanakan pada bulan Mei-Juni di LPKIL Muntilan, Magelang-Jawa Tengah. Hewan uji yang digunakan yaitu induk ikan nilem dengan bobot ikan betina ± 250 gr dan jantan ± 200 gr. Penelitian ini menggunakan metode eksperimental dengan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dan 3 ulangan yakni Perlakuan A (NaCl fisiologis 0,2 ml/kg induk), Perlakuan B (0,3 ml/kg nduk), Perlakuan C (0,4 ml/kg induk), dan Perlakuan D (0,5 ml/kg induk). Data yang diamati meliputi waktu laten, derajat pembuahan, derajat penetasan, derajat kelulushidupan dan kualitas air. Hasil penelitian menunjukkan bahwa perlakuan B menghasilkan performa reproduksi yang lebih baik dengan nilai waktu laten yaitu 9 jam, derajat pembuahan (FR) sebesar 88.50±5.29%, derajat penetasan (HR) 84.67±4.65% dan derajat kelulushidupan (SR) 68.54±5.90%. Hasil pengukuran kualitas air variabel suhu adalah 22,6ºC – 27,7ºC, DO 4,7 – 5,8 ppm dan pH 7 – 7,9. Disimpulkan bahwa penyuntikan sGnRH-a dan anti dopamin dengan dosis 0.3 ml/kg dapat meningkatkan performa reproduksi induk ikan nilem. Kata kunci: sGnRH-a dan anti dopamin, performa reproduksi, induk, Ikan nilem
The influence of vacuum heat treatment on the pore structure of earlywood and latewood of larch
Authors: Sun Bailing , Su Yingying , Wang Xiaoqing , Chai Yubo
Published: October 2022

To investigate the changes in the pore structure of earlywood and latewood (EW and LW) in larch during the heat treatment process, this study applied nitrogen adsorption and mercury intrusion porosimetry (MIP) to measure wood pore characteristics. Wood samples were heat treated within a vacuum atmosphere at temperatures between 180 and 220 °C for 6 h. Analysis conducted on nitrogen adsorption isotherms indicated that the micropores and mesopores in the cell walls were present in both untreated and heat-treated EW and LW, and that the mesopores appeared as slit-shaped pores. More pores were detected in EW compared to LW, and these primarily absorbed in the range of 1.5–4 nm. Compared with the untreated wood, the total pore volume of treated wood decreased with increasing temperatures, with decreased pore volumes at 220 °C of 63 and 42% for EW and LW, respectively. The MIP results showed a greater porosity of EW compared to LW. Compared with the untreated wood, the porosity of heat-treated EW and LW first increased with increasing temperature, and then decreased at 220 °C. For treatment temperatures lower than 200 °C, heat treatment increased the proportion of macropores with pore sizes in the ranges of 100–1000 nm and 10,000–40,000 nm.
Clinical implications of anti-idiotype antibodies in COVID-19
Authors: Shukla Ajay Kumar , Misra Saurav
Published: October 2022

Idiotype-based therapeutics have failed to deliver their promise, necessitating rethinking of the concept and its potential to develop a viable immunotherapy method. The idiotype based hypothesis is discussed in this paper in order to produce effective anti-idiotype vaccinations. Polyclonal anti-idiotype reagents have been shown to be more successful in animal models, and a better understanding of the immune response in humans supports the idea that polyclonal anti-idiotype vaccines will be more effective than monoclonal-based anti-idiotype vaccines. This innovative approach can be used to produce therapeutic antibodies in a Biotech-standard manner. The idiotype network has been tweaked in the lab to provide protection against a variety of microbiological diseases. Antibodies to image-idiotype antigens, both internal and non-internal, can elicit unique immune responses to antigens. The current outbreak of severe acute respiratory syndrome 2 (SARS-2) has presented a fantastic chance to use idiotype/anti-idiotype antibodies as a protective regimen, which might be used to treat COVID-19 patients. The development of various effective vaccinations has been crucial in the pandemic’s management, but their effectiveness has been limited. In certain healthy people, the development of viral variations and vaccinations can be linked to rare off-target or hazardous effects, such as allergic responses, myocarditis and immune-mediated thrombosis and thrombocytopenia. Many of these occurrences are most likely immune-mediated. The current analysis reveals successful idiotype/anti-idiotype antibody uses in a variety of viral illnesses, emphazising their importance in the COVID-19 pandemic.

Nicotinamide riboside supplementation ameliorated post-ovulatory oocyte quality decline
Authors: Li Hui , Wang Huan , Xu Jianmin , Zeng Xinxin , Sun Yingpu , Yang Qingling
Published: October 2022

In brief

Oocyte quality and its NAD+ level decrease with time during in vitro culture. This study shows that nicotinamide riboside (NR) supplementation improves early embryonic development potential in post-ovulatory oocytes by decreasing the reactive oxygen species (ROS) levels and reducing DNA damage and apoptosis which could potentially increase the success rate of assisted reproductive technology (ART).

The quality of post-ovulatory oocytes deteriorates over time, impacting the outcome of early embryonic development during human ART. We and other groups have found that NAD+, a prominent redox cofactor and enzyme substrate, decreases in both aging ovaries and oocytes. In this study, we found that the NAD+ levels decreased in the post-ovulatory mouse oocytes during in vitro culture and this decrease was partly prevented by NR supplementation. NR treatmenty restored MII oocyte quality and enhanced the early embryonic development potential of post-ovulatory oocytes via alleviating mitochondrial dysfunction and maintaining normal spindle/chromosome structure. Also, treatment with NR decreased ROS levels and reduced DNA damage and apoptosis in post-ovulatory oocytes. Taken together, our findings indicated that NR supplementation increases the oocyte quality and early embryonic development potential in post-ovulatory oocytes which could potentially increase the success rate of ART.

Subject and Purpose. Studying the time variations shown by the critical frequencies of the ionospheric F2 layer through comparative analysis of ionosonde data and observations of type III solar radio bursts. Methods and Methodology. In this work, two independent methods have been used for identifying critical frequencies in the ionosphere, namely that of vertical sounding and observations of type III solar radio bursts near their cut-off frequency in the ionosphere. One of the ionosondes used for vertical sounding was located near Zmiiv (Kharkiv Region), rather close to the UTR-2 radio astronomy observatory where the solar bursts were observed. The radiation from such bursts represented probe signals for transmissive sounding. The solar radiation was received with an element of a low-frequency (1 to 40 MHz) antenna array. Results. On May 22, 2021 variations in the critical frequency f0F2 of the ionospheric F2-layer were followed between 07:00 and 17:00 UT. The value reached a maximum of 5.9 MHz at 07:45 to 08:00 UT and then decreased smoothlyto 4.9 MHz, stayіng there from 15:30 till 16:45 UT. At that time, a storm of type III solar bursts was recorded with the antenna for radio observations at 1…40 MHz, revealing a cut-off effect for the bursts. As has been found,their cut-off frequency can be used for estimating the critical frequency f0F2 in the ionosphere. Conclusions. The comparative analysis of solar burst observations and frequency-and-time measurements with an ionosonde has shown possibilities for evaluating the critical frequency f0F2 in the ionosphere from the data on the cut-off frequency for solar radio-frequ

Subject and Purpose. The phase shifters intended for controlling the phase of radio signals are widely used in ultra-high frequency technology, communication systems, radar, and a variety of measuring and special-purpose radio equipment. Designers of phased array antennas face the need of providing for broad beam scanning angles and high antenna gains, which leads to the necessity of greatly increasing the number of array elements, each of which is to be controlled by a phase shifter. Therefore, the development and creation of quick-acting phase shifters is an urgent task. The purpose of this work is to develop high-speed, controllable phase shifters for performing phase angle adjustments and thus provide, at an acceptable cost, for desirable parameters of phased antenna arrays, frequency stabilizing systems of magnetrons, etc. Methods and Methodology. The functional diagram of the proposed quick-acting, controllable phase shifter has been analyzed mathematically and modelled numerically. Results. The controllable phase shifter can be successfully implemented through the use of two parallel-connected resonators at the input of a specific receiver. Analysis of the signal amplitude and phase at the output of the phase shifter in dependence on the values at the input confirms the possibility of adjusting the phase of the output signal over a wide range of angles. Conclusions. A design concept of quick-acting, controllable phase shifters for producing adjustable phase angles has been developed. The device can be employed in phased antenna arrays or frequency stabilizing systems as a means of improving their operation parameters and reducing their cost at that.

Published: October 2022

Subject and Purpose. The work has been aimed at developing and implementing a novel method of aeronomic observations in the Earth's stratosphere, applicable in the microwave range of the electromagnetic spectrum. The research is centered on a study of the measurement errors arising when the method proposed is employed for observations of the ozone spectral line (142 GHz). Methods and Methodology. The method is based on a simplified calibration procedure, in what concerns the hardware and the technology employed. In contrast to the common calibration techniques using special-purpose sources of the reference signal, we suggest resorting to natural sources, like internal noise of the receiver and the thermal radiation from the Earth's surface and the lower atmospheric layer. The measurement errors (both calculated and evaluated experimentally) have been analyzed within standard mathematical statistics techniques. Results. The tests performed during observations of the spectral line (142 GHz) of atmospheric ozone allow considering the new method as a success. The estimated magnitude of the relative error specific to the observation method proposed does not exceed 1.5%. The experimental estimate accounting for all potential error sources does not exceed 5% (with a 1 hour accumulation period), which result corresponds to the current state of the art. Conclusions. The possibility of an essential simplification of the radio optical part of the spectrometer has been demonstrated. The novel calibration technique, as well as the technical implementation thereof, can be recommended as a basis for prospective spectrometers at microwave frequencies.

Este artigo tem como objetivo analisar os dispositivos institucionais que estruturam as desigualdades educacionais no ensino médio brasileiro. Com isso, visa-se fazer uma reflexão sobre as constituições brasileiras e a legislação infraconstitucional, bem como analisar as pesquisas empíricas que versam sobre as desigualdades educacionais. Enquanto método de investigação, o estudo caracteriza-se como pesquisa bibliográfica de abordagem qualitativa, cujo levantamento foi realizado a partir da análise do desenvolvimento histórico das constituições brasileiras, da legislação infraconstitucional relacionada ao ensino médio e das pesquisas empíricas associadas à desigualdade educacional na educação básica. Concluiu-se que, no Brasil, as instituições políticas e econômicas presentes favoreceram uma histórica desigualdade estruturada em um sistema econômico, político, jurídico e educacional que não garantiu os padrões mínimos de qualidade e equidade para assegurar o acesso, permanência e o êxito dos estudantes do ensino médio. Além disso, o Estado foi incapaz de proporcionar as condições políticas, jurídicas, econômicas, sociais e educacionais para o desenvolvimento humano e o surgimento de uma educação de qualidade que garantisse a equidade e a justiça educacional, e promovesse a emancipação por meio da aquisição dos conhecimentos, habilidades, competências e atitudes oriundos do processo de educação formal.

Published: October 2022

Dentists have a high risk of contracting COVID-19, they needed to be aware of the major challenge that represents the dental practice and COVID-19. Accordingly, this study aimed: 1) to investigate the knowledge of dentists regarding COVID-19, 2) to investigate the attitudes of dentists concerning the use of personal protective equipment and, 3) to investigate the attitudes of dentists on stopping their dental practices in the framework of a contingency plan for the COVID-19 outbreak.  An online cross-sectional survey was applied to dentists (n=822). Dentists in Mexico answered the survey, which was administered before the contingency plan for the COVID-19 outbreak. Results were analyzed with descriptive statistics and with a Chi-square test (P≤0.05). Of the respondents, 99% of dentists indicated knowing what COVID-19 is, knowing most, but not all, of its signs and symptoms and knowing its mode of transmission. The 89% of dentists indicated that they always used personal protective equipment. But they did not use always wear face masks, protective eyewear, face shields, disposable gowns, and caps. Dentists were aware of the risk of performing dental procedures during the COVID-19 outbreak. The 90% of dentists indicated that they would treat only patients requiring emergency treatment, and 10% indicated that they would not treat any patients. The dentists had limited knowledge about the COVID-19 disease. They did not use personal protective equipment consistently, and they indicated that they might continue working during the COVID-19 outbreak.
When not to use machine learning: A perspective on potential and limitations
Authors: Carbone Matthew R.
Published: October 2022

The unparalleled success of artificial intelligence (AI) in the technology sector has catalyzed an enormous amount of research in the scientific community. It has proven to be a powerful tool, but as with any rapidly developing field, the deluge of information can be overwhelming, confusing, and sometimes misleading. This can make it easy to become lost in the same hype cycles that have historically ended in the periods of scarce funding and depleted expectations known as AI winters. Furthermore, although the importance of innovative, high-risk research cannot be overstated, it is also imperative to understand the fundamental limits of available techniques, especially in young fields where the rules appear to be constantly rewritten and as the likelihood of application to high-stakes scenarios increases. In this article, we highlight the guiding principles of data-driven modeling, how these principles imbue models with almost magical predictive power, and how they also impose limitations on the scope of problems they can address. Particularly, understanding when not to use data-driven techniques, such as machine learning, is not something commonly explored, but is just as important as knowing how to apply the techniques properly. We hope that the discussion to follow provides researchers throughout the sciences with a better understanding of when said techniques are appropriate, the pitfalls to watch for, and most importantly, the confidence to leverage the power they can provide.

The subject of the article are considerations regarding the cooperation between the society, the investor and the commune authorities in determining the legal conditions for the location and implementation of a housing investment Considerations are conducted on the basis of the so-called Special Purpose Flat Construction Act of 5 July 2018. The article presents possible forms of cooperation. Such possibilities exist in several areas, i.e.: when concluding an agreement on social and technical infrastructure, another example is taking into account the voices of the society in discretionary decision on the consent to the location of the investment, and yet another way of cooperation can be considered the creation by the commune of conditions for the application of the provisions of the special act, for example, by changing The Study of Determinants and Trends in Spatial Development findings as necessary. As a result of the considerations, conclusions were formulated regarding informal as well as formal forms of cooperation of the above-mentioned partners in the location and implementation of a housing investment. The article refers to the achievements of German doctrine on this subject.

Published: October 2022

The aim of the article is to show that the principles of democracy and social solidarity play a very important role in the process of organizing and conducting public collections. Thanks to the constitutionally guaranteed freedom of association, many different organizations (e.g. non-governmental organizations, social committees, social cooperatives, joint-stock companies or limited liability companies) have been allowed to participate in the implementation of public tasks, which may be financed with funds from public donation.

Authors:   Uniwersytet Rzeszowski, Polska, Kubas Sabina
Published: October 2022

Membership in an international organization is an important stage in the implementation of external and internal activities. It is the legal bond linking the state with the organization from which the rights and obligations arise. From the point of view of individual states that are members, activity in the forum of the organization is an important element of foreign policy. Diplomacy, usually developed by states on the forum of international organizations, is treated as an important instrument of international cooperation. The importance of international organizations is evidenced by the efforts of individual countries to submit their own initiatives in the forum of organizations and efforts to ensure the representation of their country in the main organs of the organization. One of the non-member statuses of participation in an international organization is partial membership, which enables full participation in one or more organs of the organization in the interest of itself and of the organization itself.

Public procurement is an area of public administration intended to serve the common good in economic growth. Ensuring efficient and competitive procedures is supposed to enable the optimal use of public funds despite increasingly difficult social or budgetary conditions. The professionalisation of public procurement should be an effective means of achieving these objectives.The changes introduced to the public procurement system have highlighted the supportive role of the President of the Public Procurement Office in activities aimed at more effective conduct of tender procedures. He has become the primary entity responsible for disseminating knowledge about public procurement. The conduct of actions aiming at permanent professionalisation will not be possible without the cooperation of the President of the Public Procurement Office with other entities involved in forming the public procurement system, only some of which perform tasks within the scope of public administration. In contrast, others are located outside the public administration structure. They include, among others: public administration bodies, administrative establishments, associations, universities or entrepreneurs. The necessity of undertaking wider and broader cooperation with entities from outside public administration is justified by a new look at the essence of public administration. It serves – first of all – the implementation of the common good. This translates into going beyond the framework of a classical approach to cooperation.

Authors:   Uniwersytet Łódzki, Polska, Białkowska Paula
Published: October 2022

The types and characteristics of guarantees created to shield Polish legal professional secrecy are the subject of this article. It is inseparably connected with the character and role of it in performing legal profession. Those guarantees are one of the most important factors in protecting legal professional confidentiality – not only crucial for the client but also for the whole legal protection system. Additionally, the main issues of lawyer’s secrecy in a criminal trial associated with a conflict of goods protected by the legal system have also been noted. Therefore, the author noticed the importance of evidence bans that are a guarantor and an element that creates trust between the parties who entrusted themselves with secrets in the process of communication related – in the case of lawyer secrets – to legal services. Moreover, there is now an increased need to protect the right to privacy, which was also observed and emphasized in this article.
Tajemnica adwokacka w polskim procesie karnym – w kierunku attorney-client privilege?
Authors:   Uniwersytet Gdański, Polska, Cora Łukasz
Published: October 2022

The article refers to the issue of attorney-client privilege in Polish criminal proceedings. The author critically evaluates the current solution based on the dichotomy of defence secret and advocacy secret, pointing to basic normative and axiological problems connected with weakening of confidential attorney-client relationship based on mutual trust. In the following part, he refers to the attorney-client privilege, which is, in his opinion, much more guaranteeing having in particular in mind the special relationship between the advocate and the client. The whole argument ends with conclusions in which the author points out the disproportionate nature of the existing solutions regarding the possibility of waiving attorney-client privilege and questioning an advocate as a witness.

Published: October 2022

Este artigo apresenta as especificidades e implicações da espiritualidade e religiosidade na velhice. Por meio da revisão integrativa da literatura, com a recuperação de estudos produzidos no período de 2015 a dezembro de 2020, foi possível constatar que a espiritualidade e religiosidade podem ser atribuídas como um mecanismo interno e externo que propiciam influências positivas na qualidade de vida, bem-estar, saúde física e emocional em população idosa, implicando diretamente no envelhecimento bem sucedido. Conclui-se que, estes, são fatores protetivos diretamente atrelados a qualidade de vida da pessoa idosa, com repercussões positivas diretas nos aspectos existenciais na velhice.
A ideologia como imanentização do eschaton: um estudo introdutório da perspectiva de Eric Voegelin
Authors: Teixeira Carlos Flavio , Fransoze Marcelo Souza
Published: October 2022

Existem diversas possibilidades de definição de ideologia, notadas nos âmbitos filosófico, político ou sociológico. Este breve estudo busca apresentar a definição de ideologia proposta por Eric Voegelin e evidenciar como o autor identifica as ideologias políticas modernas com uma imanentização do eschaton cristão. Adotando o método de revisão bibliográfica, recapitula alguns autores que formularam o conceito de ideologia, analisa as abordagens críticas em relação a ideologia, e apresenta o conceito formulado por Voegelin. Em seguida expõe o conceito de transcendência presente na escatologia cristã e finaliza apontando como se excluiu o elemento transcendente, assim criando uma escatologia secular.
O papel da espiritualidade/religiosidade na saúde mental de minorias sexuais: revisão integrativa da literatura
Authors: Da Rosa Zoé Tiago Silva , Esperandio Mary Rute Gomes
Published: October 2022

Diversas pesquisas têm demonstrado os inúmeros benefícios decorrentes da integração da espiritualidade nos cuidados em saúde, contudo entre minorias sexuais essa relação é mais complexa e paradoxal. Buscou-se, por meio deste estudo de revisão integrativa da literatura, verificar o papel da espiritualidade/religiosidade (E/R) na saúde mental de minorias sexuais. O levantamento foi realizado no mês de julho de 2020, nas seguintes bases de dados: SciELO; PUBMED; Biblioteca Virtual de Saúde; Biblioteca Digital Brasileira de Teses e Dissertações e Portal de Periódicos da CAPES. Foram selecionados para análise 27 estudos. Estes estudos evidenciaram que elementos espirituais/religiosos podem funcionar tanto como fatores de risco de piores resultados em saúde mental quanto fatores de proteção. Contudo, apesar da evidência de que a E/R pode ser um recurso de resiliência e força para melhor lidar com o sofrimento, experiências negativas com a E/R têm um impacto mais proeminente na saúde mental destas populações. Estes resultados sugerem a necessidade de um cuidado em Saúde que seja sensível às crenças e práticas espirituais de minorias sexuais, potencializando recursos protetivos que auxiliem no enfrentamento e ressignificação de experiências negativas. Especialistas em assistência espiritual poderiam contribuir no atendimento das demandas específicas destas populações por meio de uma assistência espiritual inclusiva livre de qualquer tipo de julgamentos e condenações.
A terapêutica do religioso na pandemia: uma leitura sociofilosófica da questão
Authors: Hahn Noli Bernardo , Vianna Lucas Oliveira , Mendonça Matheus Thiago Carvalho
Published: October 2022

A crise sanitária desencadeada pela pandemia de Covid-19 ensejou a rápida implementação de medidas de distanciamento social. Decretos públicos implicaram a suspensão irrestrita de liturgias religiosas públicas. Nesse contexto, desenvolve-se uma análise sociológica e filosófica da questão: as medidas excepcionais adotadas avaliaram adequadamente a relevância socioantropológica e terapêutica do fenômeno religioso? Adotando a revisão bibliográfica e a análise qualitativa como metodologia principal, o trabalho harmoniza os conceitos de secularismo moderno (Taylor), vida e religião como bens humanos básicos incomensuráveis (Finnis) e espiritualidade como elemento constitutivo central do sujeito (Frankl) para, por fim, abordar casos limítrofes da ponderação entre saúde pública e liberdade religiosa, a fim de avaliar a proporcionalidade das medidas empregadas.

New interventions and sustainable solutions: Reappraising illegal artisanal mining in South Africa
Authors: Mkhize Mbekezeli Comfort
Published: October 2022

Despite being recognised as a significant contributor in the South African economy, the mining industry is riddled with illegal mining activities. Though it remains difficult to precisely measure the extent of the activities in financial terms, it is estimated that more than R72 Billion have been lost. Lack of research on illegal mining partly compounds the problem. In view of this knowledge-gap, this article argues that whilst there is a multiplicity of stakeholders who deal directly with unlawful activities, poor integration of capacities at different levels remain discernible. The article assesses available literature and employs two theoretical perspectives as lenses through which to view the underlying reasons and the measures that can be put in place to quell illegal mining. The article concludes that an integrated model needs to be put in place in order to quell illegal mining in South Africa. The article recommends that the resources need to be pulled together and collaborative efforts need to be enhanced at all levels.
A losing battle? Assessing the detection rate of commercial crime
Authors: Budhram Trevor , Geldenhuys Nicolaas
Published: October 2022

The South African Police Service (SAPS) is finding it increasingly difficult to protect victims from the scourge of commercial crime which threatens the economy, corrodes scarce and valuable resources, and inhibits growth and development. Official statistics from the SAPS show that the annual detection rate in respect of reported fraud cases was 35.77% in 2014/15 and 34.08% in 2015/16. Although the detection rate for serious commercial crime for 2014/15 is reported as 94.8% and 96.75% for 2015/16, it is likely that these figures are inaccurate and in reality are much lower. This article provides an overview of the incidence of commercial crime, assesses the detection rate reported by the SAPS and seeks to determine whether they are losing the fight against these crimes.
Mass killings and calculated measures: The impact of police massacres on police reform in South Africa
Authors: Lamb Guy
Published: October 2022

Over the past two centuries, the police have perpetrated massacres in response to protest action in numerous countries. Available scholarly literature has typically focused on the circumstances that contributed to such mass killings, but rarely has there been consideration of the impact that such massacres subsequently may have had on the police organisation. Hence, this article will explore the relationship between massacres perpetrated by the police and police reform, with a particular focus on South Africa. The article concludes that, in the context of public order policing, massacres perpetuated by the police can contribute towards relatively immediate police reforms, particularly in terms of police strategies and tactics. In some circumstances, massacres have even led to some restructuring of the police organisation. The nature of the government and the policing environment appeared to be key determinants of the types of police reforms, post-massacre.
