This study aims to examine whether the adoption of the Global Reporting Initiative (GRI) Standards enhances carbon emission disclosure among banks in Indonesia. Furthermore, it provides empirical evidence that the presence of women on boards moderates the relationship between GRI adoption and carbon emission disclosure. The study was conducted on 40 conventional and Islamic banks listed on the Indonesia Stock Exchange (IDX) during the period 2015–2021. The analysis employs Ordinary Least Squares (OLS) regression, with robustness tests conducted using alternative measurement variables to ensure the consistency of the results. The findings consistently demonstrate that the adoption of GRI Standards positively influences carbon emission disclosure in Indonesian banks. The presence of women on boards promotes banks’ engagement in global climate change agendas, aligning with the implementation of Sustainable Development Goals (SDGs) 5, 8, and 13. This study reinforces stakeholder theory and Critical Mass Theory, indicating that a minimum threshold of female board members is necessary to influence strategic decisions, particularly in encouraging voluntary disclosures such as carbon emission reporting. Notably, the study also finds that carbon emission disclosure is valued by banking stakeholders in Indonesia. Therefore, policymakers are encouraged to establish regulations that mandate GRI adoption and ensure a minimum representation of women in strategic decision-making positions within the banking sector.

The paper examines the challenges of training educators to organize an inclusive educational environment in the context of the existential threat to the Ukrainian nation. It is stated that epistemic injustice, which the authors consider in the aspects of hermeneutical and testimonial injustice caused by the colonial policies of the aggressor state, must be addressed through mechanisms that ensure the resilience of the multi-ethnic Ukrainian nation. It is determined that this national identity comprises a complex of individual and community identities, the formation of which requires a decolonial and inclusive approach. The authors describe a study exploring the understanding of the historical period of the Ukrainian Sich Rifles among future teachers, students with special educational needs, parents, and community members. The study also examines the influence of this historical period on the formation of national identity and statehood in the first half of the 20th century and its connection to contemporary realities. It was found that respondents lack well-structured knowledge and skills in analytically comparing historical periods and the present. A methodology was developed and proposed for preparing educators and fostering inclusive interaction between teachers and students with hearing disorders. This methodology synthesizes elements of national-patriotic education using materials from the historical epoch of the Ukrainian Sich Rifles. The hypothesis was confirmed that the sign language used by deaf and hard-of-hearing Ukrainians contains elements of the calqued Russian language but lacks unique signs to denote many nationally significant linguistic units. The study substantiates the following tasks: equipping future educators and students with a contextual understanding of the historical era of the Ukrainian Sich Rifles, focusing on its educational and cultural dimensions during the liberation movements of the early 20th century; developing methods for analyzing the ideological foundations and cultural practices of that period for modern students and schoolchildren through the awareness and formation of generational continuity and connections; incorporating elements of patriotic education into inclusive practices; fostering a nationally conscious sign-language identity; and informing the international community about more than a century of Ukraine's efforts to assert its nationhood. The article emphasizes that access for young people with hearing disorders to the historical, cultural, and linguistic heritage of the nation is a vital aspect of their inclusion in the creation and defense of the state.

Regional development is the main vector of the state's regional economic policy. Policies aimed at stimulating economic activity in a specific region of the country are always important. As a rule, the object of regional policy is economically backward compared to its neighboring territories. After Georgia gained independence, regional economic policy was implemented on various scales and using various instruments. However, due to the political and economic processes developing in the country in the first decade, these efforts were minimal. The paper discusses in detail the specifics of the formation of gross domestic product and regional characteristics in Georgia, and analyzes the contribution of regions to GDP generation. The differentiation of regions according to types of economic activity and the difficulties caused by the asymmetric development of regions are presented. The irrational and asymmetrical distribution of resources among regions is the main condition for the weakening of the country. This is reflected in development inequalities and socio-economic problems. The joint efforts of the regions in terms of integrating labor, financial, and natural resources will contribute to solving the problems of regional economic development. It is necessary to develop standards for territorial economic development strategies, a unified methodology, tools, and performance indicators for the strategic planning process. This requires the implementation of legislative and other regulatory and normative changes. It is necessary to conduct regular analysis of regional opportunities, the resulting rankings of which will allow us to assess investment attractiveness and identify challenges.

Global warming can be caused by various sectors, one of which is the transportation sector. The use of gasoline is one of the main contributors to energy consumption. Conventional cars typically use gasoline as fuel to support the mobility of their users. The use of this fuel can have negative impacts on the environment, such as greenhouse gas emissions and air pollution. Therefore, electric vehicles could be a potential solution to reduce these impacts. However, it cannot be denied that there are several barriers to the adoption of electric vehicles. Through the Theory of Planned Behavior (TPB) analysis, this study explores the influence of attitudes toward behavior, subjective norms, and perceived behavioral control on the intention to purchase electric vehicles among millennials. Additionally, it examines the motivations of millennials in their purchase intentions and the moderating role of gender in the intention to buy electric vehicles. The study sample consists of millennials living in the Jabodetabek area with an interest in electric vehicles. A quantitative method with a Structural Equation Modeling (SEM)-PLS approach is used to analyze the relationships among the variables studied. The results show that TPB and motivation influence the intention to purchase electric vehicles among millennials in Jabodetabek. Meanwhile, gender moderation only influences the relationship between perceived behavioral control and the intention to buy electric vehicles among millennials in Jabodetabek.

A search for the decay $B^0 \rightarrow φφ$ is made using $pp$ collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of $9$ fb$^{-1}$. No significant signal is observed, and an upper limit on the branching fraction of $1.3~(1.4)\times 10^{-8}$ at $90 ~(95) \%$ confidence level is set. This result supersedes the previous LHCb study and improves the upper limit by a factor of two.

The first evidence for the decay $B^-\rightarrow D^{**0}τ^-\overline{ν_τ}$ is obtained using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb$^{-1}$ , at centre-of-mass energies of 7, 8 and 13 Tev. Here, the $D^{**0}$ meson represents any of the three excited charm mesons $D_{1}(2420)^{0}$, $D_{2}^{*}(2460)^{0}$, and $D_{1}^{'}(2400)^{0}$. The $B^-\rightarrow D^{**0}τ^-\overline{ν_τ}$ signal is measured with a significance of 3.5 $σ$, including systematic uncertainties. The combined branching fraction $BR(B^-\rightarrow D^{**0}_{1,2}τ^-\overline{ν_τ})\times BR(D^{**0}_{1,2}\rightarrow D^{*+}π^-)$, where $D^{**0}_{1,2}$ denotes both $D_{1}(2420)^{0}$ and $D_{2}^{*}(2460)^{0}$ contributions, is measured to be $(0.051\pm0.013(stat)\pm 0.006(syst)\pm 0.009(\rm{ext}) )\%$, where the last uncertainty reflects that of the branching fraction of the normalisation channel $B^-\rightarrow D^{**0}_{1,2}D_s^{(*)-}$. The ratio between the tauonic and muonic semileptonic $B$ decays, with the latter taken from world average values, is also determined and found to be ${\cal R}(D^{**0}_{1,2})=0.13\pm0.03(stat)\pm0.01(syst)\pm0.02\,(\rm{ext})$.

A sample of $pp$ collision data, corresponding to an integrated luminosity of 5.4 fb$^{-1}$ and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of the lifetime of the ${\itΞ}_b^0$ baryon to that of the ${\itΛ}_b^0$ baryon, $r_τ\equivτ_{{\itΞ}_b^0}/τ_{{\itΛ}_b^0}$. The value ${r_τ^{\rm Run\,2}=1.004\pm0.009\pm0.006}$ is obtained, where the first uncertainty is statistical and the second systematic. This value is averaged with the corresponding value from Run 1 to obtain ${r_τ = 1.004\pm0.008\pm0.005}$. Multiplying by the known value of the ${\itΛ}_b^0$ lifetime yields ${{τ_{{\itΞ}_b^0}} = 1.475\pm0.012\pm0.008\pm0.009~{\rm ps}}$, where the last uncertainty is due to the limited knowledge of the ${\itΛ}_b^0$ lifetime. This measurement improves the precision of the current world average of the ${\itΞ}_b^0$ lifetime by about a factor of two, and is in good agreement with the most recent theoretical predictions.

A test of lepton universality between muons and electrons is performed using $B^+\to K^+\ell^+\ell^-$ decays (where $\ell$ = $e$, $μ$), in the dilepton invariant-mass-squared region above 14.3 GeV$^2/c^4$. The data used for the measurement consists of beauty meson decays produced in proton-proton collisions, corresponding to an integrated luminosity of 9 $\text{fb}^{-1}$, collected by the LHCb experiment between 2011 and 2018. The ratio of branching fractions for $B^+\to K^+μ^+μ^-$ and $B^+\to K^+e^+e^-$ decays is measured to be $R_K = 1.08^{+0.11}_{-0.09}\;(\text{stat})\;^{+0.04}_{-0.04}\;(\text{syst})$, which is consistent with the Standard Model prediction of unity. This constitutes the most precise test of lepton flavour universality using $B^+\to K^+\ell^+\ell^-$ decays with dilepton invariant-mass-squared above the $ψ(2S)$ mass, whilst being the first of its kind at a hadron collider.

An amplitude analysis of $B^-\rightarrow D^- D^0 K_\mathrm{S}^0$ decays is performed using proton-proton collision data, corresponding to an integrated luminosity of $9\,\text{fb}^{-1}$, collected with the LHCb detector at center-of-mass energies of 7, 8, and 13$\mathrm{\,Te\kern -0.1em V}$. A resonant structure of spin-parity $0^+$ is observed in the $D^0 K_\mathrm{S}^0$ invariant-mass spectrum with a significance of $5.3\,σ$. The mass and width of the state, modeled with a Breit$-$Wigner lineshape, are determined to be $2883\pm11\pm8\mathrm{\,Me\kern -0.1em V\!/}c^2$ and $87_{-47}^{+22}\pm17\mathrm{\,Me\kern -0.1em V}$ respectively, where the first uncertainties are statistical and the second systematic. These properties and the quark content are consistent with those of the open-charm tetraquark candidate $T_{cs 0}^{*}(2870)^0$ observed previously in the $D^+ K^-$ final state of the $B^-\rightarrow D^- D^+ K^-$ decay. This result confirms the existence of the $T_{cs 0}^{*}(2870)^0$ state in a new decay mode. The $T_{cs1}^{*}(2900)^0$ state, reported in the $B^-\rightarrow D^- D^+ K^-$ decay, is also searched for in the $D^0 K_\mathrm{S}^0$ invariant-mass spectrum of the $B^- \rightarrow D^- D^0 K_\mathrm{S}^0$ decay, without finding evidence for it.

Lepton flavour universality in rare $b\rightarrow s$ transitions is tested for the first time using $B_s^0$ meson decays. The measurements are performed using $pp$ collision data collected by the LHCb experiment between 2011 and 2018, corresponding to a total integrated luminosity of 9$\,{\rm fb}^{-1}$. Branching fraction ratios between the $B_s^0 \rightarrow φe^+e^-$ and $B_s^0 \rightarrow φμ^+μ^-$ decays are measured in three regions of dilepton mass squared, $q^2$, with $0.1 < q^2 < 1.1$, $1.1 < q^2 < 6.0$, and $15 < q^2 < 19\,{\rm GeV}^2/c^4$. The results agree with the Standard Model expectation of lepton flavour universality.

The $C\!P$ asymmetry and branching fraction of the CKM-suppressed decay $B^+\!\to J\mskip -3mu/\mskip -2muψ\,π^+$ are precisely measured relative to the favoured decay $B^+\!\to J\mskip -3mu/\mskip -2muψ\,K^+$, using a sample of proton-proton collision data corresponding to an integrated luminosity of $5.4~\mathrm{fb}^{-1}$ recorded at center-of-mass energy of $13~\mathrm{TeV}$ during 2016--2018. The results of the $C\!P$ asymmetry difference and branching fraction ratio are \begin{align*} Δ\mathcal{A}^{C\!P} &\equiv \mathcal{A}^{C\!P}(B^+ \to J\mskip -3mu/\mskip -2muψ\,π^+) - \mathcal{A}^{C\!P}(B^+ \to J\mskip -3mu/\mskip -2muψ\,K^+) = (1.29 \pm 0.49 \pm 0.08) \times 10^{-2}, \end{align*} \begin{equation*} \mathcal{R}_{π/K} \equiv \frac{\mathcal{B}(B^+ \!\to J\mskip -3mu/\mskip -2muψ\,π^+)}{\mathcal{B}(B^+ \!\to J\mskip -3mu/\mskip -2muψ\,K^+)} = (3.852 \pm 0.022 \pm 0.018) \times 10^{-2}. \end{equation*} where the first uncertainties are statistical and the second systematic. A combination with previous LHCb results based on data collected at $7$ and $8~\mathrm{TeV}$ in 2011 and 2012 yields $Δ\mathcal{A}^{C\!P} = (1.42 \pm 0.43 \pm 0.08) \times 10^{-2}$ and $\mathcal{R}_{π/K} = (3.846 \pm 0.018 \pm 0.018) \times 10^{-2}$. The combined $Δ\mathcal{A}^{C\!P}$ value deviates from zero by 3.2 standard deviations, providing the first evidence for direct $C\!P$ violation in the amplitudes of beauty decays to charmonium final states.

An amplitude analysis of the $D_{s1}(2460)^+\to D_{s}^{+}π^{+}π^{-}$ transition is performed simultaneously in $B^{0}\to D^{-}D_{s}^{+}π^{+}π^{-}$, $B^{+}\to{\bar{D}}^{0} D_{s}^{+}π^{+}π^{-}$, and $B^{0}\to D^{*-}D_{s}^{+}π^{+}π^{-}$ decays. The study is based on a data sample of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of $\sqrt{s}=7,8,$ and $13\,$TeV, corresponding to a total integrated luminosity of $9\,\rm{fb}^{-1}$. A clear double-peak structure is observed in the $m(π^{+}π^{-})$ spectrum of the $D_{s1}(2460)^{+}\to D_{s}^{+}π^{+}π^{-}$ decay. The data can be described either with a model including $f_0(500)$, $f_0(980)$ and $f_2(1270)$ resonances, in which the contributions of $f_0(980)$ and $f_2(1270)$ are unexpectedly large, or with a model including $f_0(500)$, a doubly charged open-charm tetraquark state $T_{c\bar{s}}^{++}$ and its isospin partner $T_{c\bar{s}}^{0}$. If the former is considered implausible, the $T_{c\bar{s}}$ states are observed with high significance, and the data are consistent with isospin symmetry. When imposing isospin constraints between the two $T_{c\bar{s}}$ states, their mass and width are determined to be $2327\pm13\pm13\,$MeV and $96\pm16\,^{+170}_{-23}\,$MeV, respectively, where the first uncertainty is statistical and the second is systematic. The mass is slightly below the $DK$ threshold, and a spin-parity of $0^+$ is favoured with high significance.

A study of $\itΛ_{\it{b}}^\rm{0}$ and $\itΞ_{\it{b}}^\rm{0}$ decays to $\itΛ h^{+} h^{\prime -}$ $(h^{(\prime)}=π, K)$ is performed using $pp$ collision data collected by the LHCb experiment during LHC Runs 1$-$2, corresponding to an integrated luminosity of $9~\rm{fb}^{-1}$. The branching fractions for these decays are measured using the $\itΛ_{\it{b}}^\rm{0}\to\itΛ_{\it{c}}^+(\to\itΛπ^+)π^-$ decay as control channel. The decays $\itΛ_{\it{b}}^\rm{0}\to\itΛπ^+π^-$ and $\itΞ_{\it{b}}^\rm{0}\to\itΛK^-π^+$ are observed for the first time. For decay modes with sufficient signal yields, $CP$ asymmetries are measured in the full and localized regions of the final-state phase space. Evidence is found for $CP$ violation in the $\itΛ_{\it{b}}^\rm{0}\to\itΛK^+K^-$ decay, interpreted as originating primarily from an asymmetric $\itΛ_{\it{b}}^\rm{0} \to \it{N}^{*+} \it{K}^-$ decay amplitude. The measured $CP$ asymmetries for the other decays are compatible with zero.

The first study of $J/ψφ$ production in diffractive processes in proton-proton collisions is presented. The study is based on an LHCb dataset recorded at centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5 fb$^{-1}$. The data disfavour a nonresonant $J/ψφ$ production but are consistent with a resonant model including several resonant states observed previously only in $B^+ \to J/ψφK^+$ decays. The $χ_{c0}(4500)$ state is observed with a significance over $6σ$ and the $χ_{c1}(4274)$ is confirmed with a significance of more than $4σ$.

A search for the fully reconstructed $B_s^0 \rightarrow μ^+μ^-γ$ decay is performed at the LHCb experiment using proton-proton collisions at $\sqrt{s}=13$\,TeV corresponding to an integrated luminosity of $5.4\,\mathrm{fb^{-1}}$. No significant signal is found and upper limits on the branching fraction in intervals of the dimuon mass are set \begin{align} {\cal B}(B_s^0 \rightarrow μ^+μ^-γ) < 4.2\times10^{-8},~&m(μμ)\in[2m_μ,~1.70]\,\mathrm{GeV/c^2} ,\nonumber {\cal B}(B_s^0 \rightarrow μ^+μ^-γ) < 7.7\times10^{-8},~&m(μμ)\in[1.70,~2.88]\,\mathrm{GeV/c^2},\nonumber {\cal B}(B_s^0 \rightarrow μ^+μ^-γ) < 4.2\times10^{-8},~&m(μμ)\in[3.92 ,~m_{B_s^0}]\,\mathrm{GeV/c^2},\nonumber \end{align} at 95\% confidence level. Additionally, upper limits are set on the branching fraction in the $[2m_μ,~1.70]\,\mathrm{GeV/c^2}$ dimuon mass region excluding the contribution from the intermediate $φ(1020)$ meson, and in the region combining all dimuon-mass intervals.

The four decays, $Λ_{b}^{0} \rightarrow Σ_c^{(*)++} D^{(*)-} K^{-}$, are observed for the first time using proton-proton collision data collected with the LHCb detector at a centre-of-mass energy of $13\,\rm{TeV}$, corresponding to an integrated luminosity of $6\,\rm{fb}^{-1}$. By considering the $Λ_b^0 \rightarrow Λ_c^{+} \overline{D}^0 K^{-}$ decay as reference channel, the following branching fraction ratios are measured to be $$\frac{\cal{B} (Λ_{b}^{0} \rightarrow Σ_{c}^{++} \rm{D}^{-} {K}^{-})}{\cal{B}(Λ_{b}^{0} \rightarrow Λ_c^{+} \rm \overline{D}^0 {K}^{-})} = {0.282}\pm{0.016}\pm{0.016}\pm{0.005}, \frac{\cal{B}(Λ_{b}^{0} \rightarrow Σ_{c}^{*++} \rm {D}^{-} {K}^{-})}{\cal{B}(Λ_{b}^{0} \rightarrow Σ_c^{++} \rm {D}^{-} {K}^{-})} = {0.460}\pm{0.052}\pm{0.028}, \frac{\cal{B}(Λ_{b}^{0} \rightarrow Σ_{c}^{++} \rm {D}^{*-} {K}^{-})}{\cal{B}(Λ_{b}^{0} \rightarrow Σ_c^{++} \rm {D}^{-} {K}^{-})} = {2.261}\pm{0.202}\pm{0.129}\pm{0.046}, \frac{\cal{B}(Λ_{b}^{0} \rightarrow Σ_{c}^{*++} \rm D^{*-} K^{-})}{\cal{B}(Λ_{b}^{0} \rightarrow Σ_c^{++} \rm D^{-} K^{-})} = {0.896}\pm{0.137}\pm{0.066}\pm{0.018},$$ where the first uncertainties are statistical, the second are systematic, and the third are due to uncertainties in the branching fractions of intermediate particle decays. These initial observations mark the beginning of pentaquark searches in these modes, with more data set to become available following the LHCb upgrade.
